Psychodiabetology: The Challenge of the Future?

The number of people suffering from diabetes, including type 1, is constantly increasing both in Poland and worldwide. Type 1 diabetes is a chronic disease characterized by uncertain prognosis and relapses, as well as permanent, irreversible, and progressive changes in health status. The ongoing disease results in dysfunction or disability, and the patient requires specialized supervision, care, and rehabilitation. However, the success of therapy does not depend solely on the perfection of treatment, but also on the patient's readiness to change their lifestyle and cooperate with the therapeutic team. The patient's constant alertness in making therapeutic decisions does not always lead to expected treatment results, and the risk of hypoglycemia associated with intensive insulin treatment depletes the patient's motivation for treatment, leading over time to the development of 'therapeutic burnout' and psychiatric disorders. This narrative review is an attempt to summarize the knowledge and possible future solutions in diabetes type 1 in Poland as well as highlight the importance of comprehensive care, including psychological care, which appears fundamental in a chronic disease such as type 1 diabetes. Therefore, the aim of the study was to present generational changes and psychosocial problems of patients with type 1 diabetes and to identify urgent challenges in diabetic care. Attention should be paid to the deteriorating mental condition of the young generations, who, in the course of diabetes, are exposed to additional psychological and psychiatric health problems. The next generation of patients will require more psychological care, which is why the challenge of the future is to create psychodiabetology centers.

Role Modeling Kindness at the Bedside

Compassion and kindness are interchangeable attitudes and behaviors in society. As evidence shows the importance of compassion and kindness in healthcare, there has been a push to nurture and teach compassion through experiential learning in medical schools. However, there is not much evidence of educating learners on the importance of kindness as the complement or foundation of compassion and empathy. Kindness is the ability to act positively and appropriately and can be provided without emotion, judgment, or expecting anything in return. Kindness does not require the receiver to be in severe distress or suffering. Acts of kindness can be random acts done to anyone, anytime, with or without illness or suffering. Research shows that kindness elevates the healthcare profession for both clinicians and patients. Compassion and kindness must be taught through the integrated approach of role modeling, observation, practice, experience, and reflection in the classroom and in the clinical environment. It is vital that medical schools and healthcare institutions' faculty and staff make kindness to patients, families, and staff a key behavior, along with compassion and empathy. There is more that can be done to encourage acts of kindness through everyday actions; educators can display kindness toward colleagues and medical students in their learning. Kindness can improve conversations with patients and improve the emotional and social well-being of learners. Displaying kindness during bedside or classroom teaching would engrain its importance in the professional identity formation of future generations of physicians.

Generational Differences in Food Choices and Consumer Behaviors in the Context of Sustainable Development

(1) Background: This study examines diverse food choices and sustainable consumption behavior across four generations of Poles: Baby Boomers, Generation X, Generation Y, and Generation Z. (2) Methods: The research employed an online survey with a quota sample of 1000 individuals, representing the Polish population in terms of gender, residence, and education (categorized into two groups). (3) Results: For Poles, the crucial factors in food selection were product quality (69.0%), price (68.6%), and information about the product's composition (41.0%). Older cohorts (Baby Boomers and Generation X) prioritized food quality, while younger generations (Generation Y and Generation Z) emphasized price. Statistically significant differences emerged between generations regarding the product's country of origin, with older generations emphasizing its importance more. The oldest group (Baby Boomers) considered ecological certification most important. As much as 85.9% of Poles checked product expiration dates while buying products, and 82.8% bought only as much as they needed. Baby Boomers most often exhibited these two behaviors and can be considered the most responsible among all generations. (4) Conclusions: This article highlights the importance of comprehensive sustainability efforts in the context of food choices. It takes into account the socio-cultural and historical circumstances of each generation that influence their consumer habits.

Shoulder dystocia by severity in families: A nationwide population study

INTRODUCTION

Previous studies have established a history of shoulder dystocia as an important risk factor for shoulder dystocia, but studies on shoulder dystocia by severity are scarce. It is unknown if shoulder dystocia tends to be passed on between generations. We aimed to assess the recurrence risk of shoulder dystocia by severity in the same woman and between generations on both the maternal and paternal side. We also assessed the likelihood of a second delivery and planned cesarean section after shoulder dystocia.

MATERIAL AND METHODS

This was a population-based cohort study, using data from the Medical Birth Registry of Norway. To study recurrence in the same mother, we identified 1 091 067 pairs of first and second, second and third, and third and fourth births in the same mother. To study intergenerational recurrence, we identified an individual both as a newborn and as a mother or father in 824 323 mother-offspring pairs and 614 663 father-offspring pairs. We used Bayesian log-binomial multilevel regression to calculate relative risks (RR) with 95% credible intervals.

RESULTS

In subsequent deliveries in the same woman the unadjusted RR of recurrence was 7.05 (95% credible interval 6.39-7.79) and 2.99 (2.71-3.31) after adjusting for possible confounders, including current birthweight. The RRs were higher with severe shoulder dystocia as exposure or outcome. With severe shoulder dystocia as both exposure and outcome, unadjusted and adjusted RR was 20.42 (14.25-29.26) and 6.29 (4.41-8.99), respectively. Women with severe and mild shoulder dystocia and those without had subsequent delivery rates of 71.1, 68.9 and 69.0%, respectively. However, the rates of planned cesarean section in subsequent deliveries for those without shoulder dystocia, mild and severe were 1.3, 5.2 and 16.0%, respectively. On the maternal side the unadjusted inter-generational RR of recurrence was 2.82 (2.25-3.54) and 1.41 (1.05-1.90) on the paternal side. Corresponding adjusted RRs were 1.90 (1.51-2.40) and 1.19 (0.88-1.61), respectively.

CONCLUSIONS

We found a strong recurrence risk of shoulder dystocia, especially severe, in subsequent deliveries in the same woman. The inter-generational recurrence risk was higher on the maternal than paternal side. Women with a history of shoulder dystocia had more often planned cesarean section.

The intensification of parenting and generational fracturing of spontaneous physical activity from childhood play in the United Kingdom

Despite an increased drive over the past two decades in Western societies to promote children's physically active play to improve their health, there are concerns that childhood has become less physically active. There are also fears that a previously naturally occurring aspect of childhood has become less authentically playful. Both trends highlight changes over time in the amount and type of play practiced by children and are often cited as consequences of generational shifts. Yet, research which analytically employs the concept of generation to connect changes to childhood with relevant social transformations is lacking. Inspired by Mannheim's conceptualisation of generations, this paper draws on life history interviews with 28 United Kingdom residents born between 1950 and 1994 to propose a fracturing of naturally occurring physical activity from childhood play. As shifts in childhood and parenting have become inextricably linked, this argument illustrates the impact of an intensification to parenting upon greater parental surveillance of increasingly organised forms of childhood physical activity at the expense of spontaneous play. Future physical activity policy should be sensitive to the social climate in which recommendations for children are made, as this places expectations upon parents due to how childhood is currently understood within neoliberal contexts.

Generations, events, and social movement legacies: Unpacking social change in English football (1980-2023)

This article critically employs the case of association football in England, from 1980 to 2023, as a social movement timescape, to examine the political consciousness and long-term mobilisations of a generation of football supporter activists, and their capacity to influence politics, and respond to new, emerging, critical junctures, through networks of trust and shared memories of historical events. This is of crucial importance to sociology because it reveals the tensions between what are considered legitimate and illegitimate social practices which characterise contemporary society's moral economy. Focusing on temporal contestations over regulation, policing, governance and cultural rituals, the article deconstructs the role of generations in social movements, and critically synthesises relational-temporal sociology and classic and contemporary work on the sociology of generations, to show how legacy operates as a multifaceted maturing concept of power and time. In English football's neoliberal timescape, the supporters' movement has reached a critical juncture; the future will require a new generation of activists, to negotiate, resist and contest the new hegemonic politics of social control and supporter engagement.

Active around the year: Butterflies and moths adapt their life cycles to a warming world

Living in a warming world requires adaptations to altered annual temperature regimes. In Europe, spring is starting earlier, and the vegetation period is ending later in the year. These climatic changes are leading not only to shifts in distribution ranges of flora and fauna, but also to phenological shifts. Using long-term observation data of butterflies and moths collected during the past decades across northern Austria, we test for phenological shifts over time and changes in the number of generations. On average, Lepidoptera adults emerged earlier in the year and tended to extend their flight periods in autumn. Many species increased the annual number of generations. These changes were more pronounced at lower altitudes than at higher altitudes, leading to an altered phenological zonation. Our findings indicate that climate change does not only affect community composition but also the life history of insects. Increased activity and reproductive periods might alter Lepidoptera-host plant associations and food webs.

Digital Leadership's Influence on Individual Creativity and Employee Performance: A View through the Generational Lens

Today's digitalized business atmosphere places significant emphasis on digital leadership, as digital transformation can only be successful for leaders who are capable of overseeing the entire digitalization process. In this study, we examine the employee-level outputs of digital leadership in terms of individual creativity and employee performance. Based on the data of 348 employees and by using PLS-SEM, we find that (i) digital leadership is a significant antecedent of individual creativity, and (ii) individual creativity fully mediates the relationship between digital leadership and employee performance. When digital leadership abilities are a matter of concern, it becomes necessary to mention the importance of generational differences between those leaders, as OB studies also underline the generational differences toward new technologies. Hence, we also conducted a multigroup analysis (MGA) to determine if those interrelationships among digital leadership, individual creativity, and employee performance differ due to the generations of the managers. Surprisingly, the MGA results reveal minor differences. The findings of this study highlight the importance of embracing digital leadership in fostering a creative and high-performing work environment and provide insights for organizations aiming to harness the unique strengths and talents of their multigenerational workforce. Digital leaders who foster a culture of innovation, adaptability, and open communication can inspire employees to think creatively and come up with novel ideas. By leveraging digital tools and providing a supportive environment, digital leaders can also enhance employee creativity and performance.

A panoramic view of technological landscape for bioethanol production from various generations of feedstocks

Bioethanol is an appropriate alternate energy option due to its renewable, nontoxic, environmentally friendly, and carbon-neutral nature. Depending upon various feedstocks, bioethanol is classified in different various generations. First-generation ethanol created a food vs fuel problem, which was overcome by second-generation, third-generation and fourth-generation ethanol. The considerable availability of lignocellulosic biomass makes it a suitable feedstock, however, its recalcitrant nature is the main hurdle in converting it to bioethanol. The present study gives a comprehensive assessment of global biofuel policies and the current status of ethanol production. Feedstocks for first-generation (sugar and starch-based), second-generation (lignocellulosic biomass and energy crops), third-generation (algal-based) and fourth-generation (genetically modified algal biomass or crops) are discussed in detail. The study also assessed the process for ethanol production from various feedstocks, besides giving a holestic background knowledge on the bioconversion process, factors affecting bioethanol production, and various microorganisms involved in the fermentation process. Biotechnological tools also play a pivotal role in enhancing process efficiency and product yield. In adddition, most significant development in the field of genetic engineering and adaptive evolution are also highlighted.

The pros and cons of fertility awareness and information: a generational, Swedish perspective

Being aware of factors that affect fertility can help people make informed decisions about their reproductive futures. To some, however, fertility information leads to worry and self-blame. In this paper, we explore how people from different generations discuss fertility and reproductive decision-making, along with their perceptions of fertility information. The study was conducted in southern Sweden with 26 focus-group discussions that included a total of 110 participants aged 17-90 years. The material was analysed thematically. Our results show that fertility knowledge and openness to talking about fertility problems have increased over generations. Participants who were assigned female at birth were more often concerned about their fertility than those who were not, and fertility concerns were transferred from mothers to daughters. While age-related fertility concerns had been uncommon in older generations, participants aged 25-40 often expressed these concerns. Young adults appreciated being knowledgeable about fertility but simultaneously expressed how fertility information could lead to distress. Our conclusion is that fertility information was best received by high-school students, and efforts to improve fertility education in schools are therefore recommended.

Kinship and socio-economic status: Social gradients in frequencies of kin across the life course in Sweden

The influence of kin on various outcomes is heavily debated. However, kinship size itself conditions the probability of potential effects. Socio-economic gradients in the prevalence, variance, and types of kin are, therefore, a vital aspect of the functions of kin. Unfortunately, these parameters are largely unknown. We used Swedish register data to enumerate consanguine and in-law kin across the life course of the 1975 birth cohort. We calculated differences in kinship size between this cohort's income quartiles and educational groups. We decomposed how specific kin relations, generations, and demographic behaviours contributed to these differences. Among low socio-economic status (SES) groups, higher fertility in earlier generations resulted in more kin compared with high-SES groups. Low-SES groups had more horizontal consanguine kin, while high-SES groups had more in-laws. Lower fertility and higher union instability among low-SES men substantially narrowed SES differences in kinship size. Kinship size varied substantially within SES groups.

Effect of childbearing-age women's family status on the health status of three generations: evidence from China

It is widely recognized that inequalities in social status cause inequalities in health. Women in a family often directly influence three generations-women themselves, their children and their parents -yet the effect of women's family status on their own health status and that of the two generations before and after is not clear. Taking data from the China Family Panel Studies, this study used an ordered response model to investigate the effect of childbearing-age women's family status on the health status of three generations. The results showed that increases in childbearing-age women's family status improved the health status of the women themselves and their children. Unlike previous studies, however, we found that higher family status did not improve parents' health status but decreased it. The mechanism analysis indicated that women's family status influenced the health status of three generations through economic conditions, resource allocation, and child discipline. The results held after robustness testing. Our findings contribute to knowledge in related fields and provide theoretical support for policies that empower women.

At your service: supportiveness of servant leadership, communication frequency and communication channel fostering job satisfaction across generations

Introduction

The present study contributes to the conversations on the role of 'autonomy supportive' factors in employee wellbeing in remote work contexts by examining the relationships between servant leadership, communication frequency - overall and via synchronous (i.e., individual video-calls, individual telephone calls) and asynchronous communication channels (i.e., e-mail messages, and WhatsApp) - on the one hand, and job satisfaction, on the other, and the moderating role of generation (Baby Boomers and Gen X versus Gen Y) in these relationships.

Method

Building on self-determination theory, incorporating insights from servant leadership, telework, and media richness and synchronicity literatures, we developed hypotheses that were tested via multilevel analysis (273 employees nested in 89 managers).

Results

In line with expectations, servant leadership had a positive relationship with job satisfaction. Total communication frequency, however, was not related to job satisfaction. Further analyses per communication channel showed that only level 2 e-mail communication frequency was positively related to job satisfaction. In contrast to expectations, the relationships studied were not moderated by generation.

Discussion

We concluded that, for all generations, both servant leadership and frequent (e-mail) communication can be regarded as 'autonomy supportive' factors in employee wellbeing. Paradoxically, whereas servant leadership, considered as a human-centric leadership style, suggests close trust-based employment relationships, employees valued frequent asynchronous communication (via e-mail). Having access to information and knowledge when needed may satisfy employees' need for autonomy (and perhaps for flexibility to engage in work and non-work activities). The insights gained in our study can inform organizations, managers, and employees, particularly in future remote work contexts.

Do applicants from Generation X, Y, Z differ in personality traits? data from selection procedures in aviation (1987-2019)

Introduction

The objective of this study is to research personality trait differences across generations and the impact of age, gender and self-presentation on these traits.

Methods

A total of 82,147 applicants (aged 17-24) for aviation training (pilot, air traffic controller), born between 1965 and 2002, were divided into three cohorts (Generation X, Y, Z). We analysed data from the temperament structure scales (TSS) personality questionnaire, which was collected during selection procedures between 1987 and 2019. Generational differences were analysed by ANCOVAs with generation and gender as group factors, controlled by age and self-presentation (social desirability).

Results

Age had no significant impact, but we observed slight gender differences in emotional stability, vitality, empathy, and self-presentation across all generations. The generational differences found exhibited extremely small effect sizes, suggesting that applicants have become more extraverted, controlled (with lower aggression and higher rigidity), and inclined to present themselves in a more favourable manner.

Discussion

We discuss the implications of these findings for the aviation industry and the applicability of Generation theory in personality trait research.

Workout Logging Through an mHealth App for Weight Reduction Among Different Generations: Secondary Analysis of the MED PSU×ThaiSook Healthier Challenge

BACKGROUND

Being overweight or obese presents a major risk factor for noncommunicable diseases (NCDs) such as cardiovascular disease, diabetes, and musculoskeletal disorders. These problems are preventable and solvable via weight reduction and increased physical activity and exercise. The number of adults who are overweight or affected by obesity has tripled in the last 4 decades. Using mobile health (mHealth) apps can help users with health issues, including reducing their weight by restricting their daily calorie intake, which can be recorded along with other parameters, such as physical activity and exercise. These features could further enhance health and prevent NCDs. ThaiSook, a Thai mHealth app developed by the National Science and Technology Development Agency, aims to promote healthy lifestyles and reduce the risk behaviors of NCDs.

OBJECTIVE

This study aimed to determine whether ThaiSook users were successful in 1-month weight reduction and identify which demographic factors or logging functions were associated with significant weight reduction.

METHODS

A secondary data analysis was performed using data collected from the "MED PSU×ThaiSook Healthier Challenge," a month-long challenge to encourage a healthy lifestyle. We enrolled 376 participants to evaluate the study outcomes. The variables, comprising demographic characteristics (ie, sex, generation, group size, and BMI), were classified into 4 groups: normal (18.5-22.9 kg/m²), overweight (23-24.9 kg/m²), obese I (25-29.9 kg/m²), and obese II (BMI ≥30 kg/m²). Logging functions (ie, water, fruit and vegetables, sleep, workout, step, and run) were classified into 2 groups: consistent (≥80%) and inconsistent (<80%) users. Weight reduction was categorized into 3 groups: no weight reduction, slight weight reduction (0%-3%), and significant weight reduction (>3%).

RESULTS

Of 376 participants, most were female (n=346, 92%), had normal BMI (n=178, 47.3%), belonged to Generation Y (n=147, 46.7%), and had a medium group size (6-10 members; n=250, 66.5%). The results showed that 56 (14.9%) participants had 1-month significant weight loss, and the median weight reduction of the group was -3.85% (IQR -3.40% to -4.50%). Most participants (264/376, 70.2%) experienced weight loss, with an overall median weight loss of -1.08% (IQR -2.40% to 0.00%). The factors associated with significant weight reduction were consistently logging workouts (adjusted odds ratio [AOR] 1.69, 95% CI 1.07-2.68), being Generation Z (AOR 3.06, 95% CI 1.01-9.33), and being overweight or being obese compared to those with normal BMI (AOR 2.66, 95% CI 1.41-5.07; AOR 1.76, 95% CI 1.08-2.87, respectively).

CONCLUSIONS

More than half of the "MED PSU×ThaiSook Healthier Challenge" participants achieved a slight weight reduction, and 14.9% (56/376) of users lost significant weight. Factors including workout logging, being Generation Z, being overweight, and being obese were associated with significant weight reduction.

Clinical performance of various bonding agents in noncarious cervical defects

Aim

Four bonding agents and a composite restorative resin were evaluated in patients having noncarious cervical defects.

Materials and Methods

This clinical trial was conducted in patients having at least 4 noncarious cervical defects in posterior teeth evaluating the clinical effectiveness in relation to retention, discoloration at margins, and postoperative sensitivity of 5th, 6th, 7th, and 8th generations of bonding agents over a period of baseline, 3, 6, 12, and 24 months.

Statistical Analysis

Data were recorded and put into statistical analysis using Chi-square tests.

Results

At 24 months, retention rate was found out to be 92.6% for the 7th generation which was better than 5th (66.7%) and 6th (70.4%) generation whereas significant marginal discoloration was seen at 6 months follow-up in which 5th generation showed maximum results. However, all the four generations have an equal score of postoperative sensitivity at all the time intervals.

Conclusions

The 7th generation adhesives performed better than other generations in terms of retention. Changes in marginal discoloration were detected at 6 months with maximum score in 5th generation adhesives.

The Influence of Birth Cohorts on Future Cognitive Decline

BACKGROUND

Slowed rates of cognitive decline have been reported in individuals with higher cognitive reserve (CR), but interindividual discrepancies remain unexplained. Few studies have reported a birth cohort effect, favoring later-born individuals, but these studies remain scarce.

OBJECTIVE

We aimed to predict cognitive decline in older adults using birth cohorts and CR.

METHODS

Within the Alzheimer's Disease Neuroimaging Initiative, 1,041 dementia-free participants were assessed on four cognitive domains (verbal episodic memory; language and semantic memory; attention; executive functions) at each follow-up visit up to 14 years. Four birth cohorts were formed according to the major historical events of the 20th century (1916-1928; 1929-1938; 1939-1945; 1946-1962). CR was operationalized by merging education, complexity of occupation, and verbal IQ. We used linear mixed-effect models to evaluate the effects of CR and birth cohorts on rate of performance change over time. Age at baseline, baseline structural brain health (total brain and total white matter hyperintensities volumes), and baseline vascular risk factors burden were used as covariates.

RESULTS

CR was only associated with slower decline in verbal episodic memory. However, more recent birth cohorts predicted slower annual cognitive decline in all domains, except for executive functions. This effect increased as the birth cohort became more recent.

CONCLUSION

We found that both CR and birth cohorts influence future cognitive decline, which has strong public policy implications.

Current updates on generations, approvals, and clinical trials of CAR T-cell therapy

Chimeric antigen receptor (CAR) T-cell therapy is a novel, customized immunotherapy that is considered a 'living' and self-replicating drug to treat cancer, sometimes resulting in a complete cure. CAR T-cells are manufactured through genetic engineering of T-cells by equipping them with CARs to detect and target antigen-expressing cancer cells. CAR is designed to have an ectodomain extracellularly, a transmembrane domain spanning the cell membrane, and an endodomain intracellularly. Since its first discovery, the CAR structure has evolved greatly, from the first generation to the fifth generation, to offer new therapeutic alternatives for cancer patients. This treatment has achieved long-term and curative therapeutic efficacy in multiple blood malignancies that nowadays profoundly change the treatment landscape of lymphoma, leukemia, and multiple myeloma. But CART-cell therapy is associated with several hurdles, such as limited therapeutic efficacy, little effect on solid tumors, adverse effects, expensive cost, and feasibility issues, hindering its broader implications.

Digital (in)equalities and user emancipation: Examining the potential of Adorno's maxim of Mündigkeit for critical intergenerational learning

The widespread use of mobile technologies has penetrated the lives of people across all age groups with the usage of smartphones and wearables appearing "natural" and without alternatives. The digitalisation of everyday life means that communication and negotiation of social and societal meanings are co-constructed by users and mobile technologies thereby blurring the boundary between on- and off-line as well as social and private spheres. At the same time, the global-market logic that has driven the extent and speed of this social transformation raises questions as to how individuals retain influence and agency over the digital technologies that have come to define both social and private spheres and that surround them at all times. Against this backdrop, this theoretical paper discusses the role of Adorno's maxim of emancipation toward autonomy (Mündigkeit) for education (Erziehung) and critical learning about and living with digital technologies. The paper suggests a way forward through intergenerational learning as a didactical method of enhancing emancipation among younger and older generations of "users" in their joint efforts of becoming critical agents in an age of digitally enhanced data markets.

Prevalence of Child Sexual Abuse in Spain: A Representative Sample Study

The prevalence of child sexual abuse (CSA) is difficult to assess, and rates vary widely across studies due to methodological and sample differences. In Spain, prevalence data from representative samples are lacking. The objective of this study was to determine the prevalence of different CSA experiences in a sample that was representative of the Spanish population in terms of gender, age, and region. The sample comprised 1,071 (539 male and 532 female) Spanish adults (M_age = 45.37; SD = 14.84). Participants completed an anonymous online survey about different types of CSA and were asked whether they had disclosed the experience at the time. Prevalence was analyzed as a function of gender and generation. Results indicated prevalence rates ranging from 2.8% to 18.5%, depending on the type of experience. The most common experience suffered during childhood was being shown pornographic material, while that with the lowest prevalence was being forced to perform a sexual act involving penetration. Prevalence was higher in females than males for eight of the ten experiences considered. Young adults from Generation Z were the most likely to report having suffered three of the CSA experiences, two of them related to technology. Only 27.5% of respondents said that they had told someone about the abuse at the time, mainly their mother (more common among females) or a friend/peer (more frequent among males). The results suggest that CSA is prevalent in Spain, with considerable rates for several types of abusive experience, especially among females and the youngest generation. The implications of the results are discussed. The findings may inform social policy and the development of effective prevention programs.

Relationship between Personal Values and Intentions to Purchase Plant-Based Meat Alternatives: Application of the Dual Concern Theory

This study examines consumers' intentions to purchase plant-based meat alternatives (PBMA), which have been created to protect animal rights, the global environment, and consumers' health. Data from 319 Korean consumers were analyzed to establish a causal relationship among personal values (egoistic, biospheric, and social-altruistic), the dual concern theory (anticipated positive effect and empathetic concern), and PBMA purchase intentions. Multigroup analysis was performed for all paths according to generation, divided into Generation MZ and the older generation; "MZ" is a compound term referring to millennials and Generation Z, who have grown up in a digital environment; this collective generation comprises individuals born after 1980. Our analysis revealed that, among personal values, biospheric and social-altruistic values had positive effects on both anticipated positive effect and empathetic concern. In turn, these aspects positively influenced PBMA purchase intentions. Particularly, anticipated positive effect had a strong influence. Finally, a moderating effect was confirmed for two paths, and only Generation MZ demonstrated the enhancing influence of biospheric value on both anticipated positive effect and empathetic concern. This study has several implications and contributes to the sustainable growth and development of PBMA and the overall food service industry.

Prevalence of cannabis use for pain management in Quebec: A post-legalization estimate among generations living with chronic pain

Background

Medical cannabis has been legal in Canada since 2001, and recreational cannabis was legalized in October 2018, which has led to a widespread increase in the accessibility of cannabis products.

Aims

This study aimed to estimate the prevalence of cannabis use among adults living with chronic pain (CP) and investigate the relationship between age and cannabis use for CP management.

Methods

A cross-sectional analysis of the COPE Cohort data set, a large Quebec sample of 1935 adults living with CP, was conducted. Participants completed a web-based questionnaire in 2019 that contained three yes/no questions about past-year use of cannabis (i.e., for pain management, management of other health-related conditions, recreational purposes).

Results

Among the 1344 participants who completed the cannabis use section of the questionnaire, the overall prevalence of cannabis use for pain management was 30.1% (95% confidence interval 27.7-32.7). Differences were found between age groups, with the highest prevalence among participants aged ≤26 years (36.5%) and lowest for those aged ≥74 years (8.8%). A multivariable logistic model revealed that age, region of residence, generalized pain, use of medications or nonpharmacological approaches for pain management, alcohol/drug consumption, and smoking were associated with the likelihood of using cannabis for pain management.

Conclusions

Cannabis is a common treatment for the management of CP, especially in younger generations. The high prevalence of use emphasizes the importance of better knowledge translation for people living with CP, rapidly generating evidence regarding the safety and efficacy of cannabis, and clinicians' involvement in supporting people who use cannabis for pain management.

"I Was Always Trying to Figure It Out… on My Own Terms": Structural Barriers, the Internet, and Sexual Identity Development among Lesbian, Gay, Bisexual, and Queer People of Different Generations

Recognizing the historical grounding of sexual identity development, we examined the spontaneous narration of the internet's significance among a diverse sample of three distinct birth cohorts of sexual minority adults (n = 36, ages 18-59) in the United States. Thematic analysis revealed two structural barriers and four roles of the internet in sexual identity development. Structural barriers were being in a heterosexual marriage (exclusive to members of the older cohort), and (2) growing up in a conservative family, religion, or community (which cut across cohorts). Roles of the internet included: learning about LGBQ+ identities and sex; watching pornography (which appeared only in narratives of the younger cohort); finding affirming community; and facilitating initial LGBQ+ romantic and sexual experiences (which appeared mostly in narratives of the younger cohort). Most participants who described the internet as playing a role in sexual identity development were members of the younger (ages 18-25) and middle (ages 34-41) cohorts. We discuss how the internet has assumed a unique role in history in the development of sexual minority people. Further, our findings highlight that sexual identity development occurs across the lifespan, and how that process and the roles of the internet vary by generation and structural realities.

Historical and generational forces in the Iridescent Life Course of bisexual women, men, and gender diverse older adults

PURPOSE

Little is known about the life course of bisexual older adults. This study examines life events and experiences of bisexuals by generation: Pride Generation, born 1950-1964; Silenced Generation, born 1935-1949; and Invisible Generation, born 1934 or earlier, as well as by gender among women, men, and gender diverse older adults.

METHODS

Aging with Pride: National Health, Aging, and Sexuality/Gender Study is the first national longitudinal study of LGBTQ older adults in the US. We utilize the Iridescent Life Course to examine the life events and life course experiences of bisexual older adults (N = 216) using 2014 survey data. The Iridescent Life Course frames this study for comparing generational and gender differences in five key areas: identity development; work; kin and social relationships; bias-related experiences; and physical and mental health.

FINDINGS

The Invisible Generation, the oldest generation, compared to the two younger generations, reports significant risks related to social relationships, the lowest levels of openly disclosing, and fewer bias-related experiences. They also demonstrate important signs of resilience and better mental health. Bisexual men and gender diverse older adults report higher rates of bias-related experiences and fewer social resources than bisexual women.

CONCLUSION

Based on the Iridescent Life Course, we document important differences in the heterogeneity and intersectionality in bisexual lives, particularly for those in late life and those gender diverse. It is essential to document the distinct nature of bisexuals' life course, as it provides both historical and contemporary insights into aging and the reframing of future research.

Birth Cohorts and Cognitive Reserve Influence Cognitive Performances in Older Adults

BACKGROUND

Evidence suggests birth cohort differences in cognitive performance of older adults. Proxies of cognitive reserve (CR), such as educational attainment and occupational complexity, could also partly account for these differences as they are influenced by the sociocultural environment of the birth cohorts.

OBJECTIVE

To predict cognitive performance using birth cohorts and CR and examine the moderating influence of CR on cognitive performance and structural brain health association.

METHODS

Using ADNI data (n = 1628), four birth cohorts were defined (1915-1928; 1929-1938; 1939-1945; 1946-1964). CR proxies were education, occupational complexity, and verbal IQ. We predicted baseline cognitive performances (verbal episodic memory; language and semantic memory; attention capacities; executive functions) using multiple linear regressions with CR, birth cohorts, age, structural brain health (total brain volume; total white matter hyperintensities volume) and vascular risk factors burden as predictors. Sex and CR interactions were also explored.

RESULTS

Recent birth cohorts, higher CR, and healthier brain structures predicted better performance in verbal episodic memory, language and semantic memory, and attention capacities, with large effect sizes. Better performance in executive functions was predicted by a higher CR and a larger total brain volume, with a small effect size. With equal score of CR, women outperformed men in verbal episodic memory and language and semantic memory in all cohorts. Higher level of CR predicted better performance in verbal episodic memory, only when total brain volume was lower.

CONCLUSION

Cohort differences in cognitive performance favor more recent birth cohorts and suggests that this association may be partly explained by proxies of CR.

Difference in Body Weight at Breeding Affects Reproductive Performance in Replacement Beef Heifers and Carries Consequences to Next Generation Heifers

Simple Summary

The effect of prebreeding feeding to attain 55% vs. 65% of mature cow body weight (MBW; 545 kg) at breeding on the reproductive performance of beef heifers and its offspring was investigated. Angus-cross dam heifers from weaning were randomly fed to attain 55% (n = 1622) vs. 65% (n = 1578) of MBW and off-spring (F1) heifers born to dam heifers in both 55% (n = 1285) vs. 65% (n = 1324) groups were fed to attain 65% of MBW. Results showed that restricted feeding negatively affected puberty, breeding season pregnancy and 21-day calving rates. F1 generation heifers that were fed normal diets but were born to dams that were fed restricted diets also had reduced puberty, breeding season pregnancy and 21-day calving rates. In conclusion, restricted feeding during the prebreeding period of dam heifers reduced post-pubertal fertility and fertility of their heifer offspring that were fed normal prebreeding diets.

Abstract

Nutrition imprinting carries consequences across generations. The effect of 55% vs. 65% of mature cow body weight (MBW; 545 kg) at breeding on the reproductive performance of heifers and their offspring was investigated. Angus-cross dam heifers were randomly fed to attain 55% (n = 1622) vs. 65% (n = 1578) of MBW, and offspring (F1) heifers born to dam heifers [55% (n = 1285) vs. 65% (n = 1324)] were fed to attain 65% of MBW. Bodyweight and reproductive indices were recorded throughout the study. In dam heifers, puberty (44% vs. 53%), breeding season pregnancy (86.4% vs. 90.6%) and 21-day calving rates (55.2% vs. 65.4%) did vary, but dystocia rate (8.7% vs. 9.0%) did not differ between 55% and 65% MBW groups. Puberty (49.2% vs. 58.2%), breeding season pregnancy (87.2% vs. 92.8%) and 21-day calving rates (53.8% vs. 64.1%) did differ (p < 0.05), but dystocia rate (8.4 vs. 9.2%) did not differ between F1 heifer groups. In conclusion, 55% of MBW at breeding negatively affected the reproductive performance of heifers and its offspring heifers. The recommendation is to feed heifers a balanced diet to reach 65% of MBW at breeding with consideration of production traits.

Gender Identity Milestones, Minority Stress and Mental Health in Three Generational Cohorts of Italian Binary and Nonbinary Transgender People

Transgender and gender nonconforming (TGNC) people experience high rates of minority stress and associated risk for negative health outcomes. However, during the last years, significant positive socio-cultural changes have happened, and younger cohorts of TGNC individuals are having diverse experiences compared to older cohorts. By integrating the minority stress theory and the life course perspective, this cross-sectional, web-based study aimed to explore in 197 Italian TGNC people aged 18 to 54 years (M = 29.82, SD = 9.64) whether the average ages of gender identity milestones (i.e., first insights about being TGNC, self-labeling as a TGNC person, and coming out), minority stress, and mental health vary among three generational cohorts (i.e., Generation Z, Millennials, and Generation X). Compared with older cohorts, younger participants: (a) were more likely to be in the trans-masculine spectrum; (b) self-labeled as TGNC and came out earlier; (c) had more negative expectations and lower levels of disclosure; and (d) had higher levels of mental health problems. No generational differences related to first insights about being TGNC and distal minority stressors were found. Furthermore, compared with binary individuals, participants with a non-binary identity: (a) reported later ages for the gender identity milestones; (b) had higher negative expectations; and (c) had higher levels of mental health problems. Overall, our findings indicated that changes in the social environments have a limited impact on stigmatization processes and mental health of Italian TGNC people.

Preconditions to parenthood: changes over time and generations

Reproductive decision-making and fertility patterns change with time and place, and are influenced by contemporary societal factors. In this paper, we have studied biosocial aspects of reproductive decision-making over time and generations in a Nordic setting. The aim was to explore intergenerational changes and influences on decision-making, especially regarding preconditions to first birth. Twenty-six focus group interviews were conducted in southern Sweden, including a total of 110 participants aged 17-90 years. The analysis of the interviews resulted in six themes: (i) 'Providing security - an intergenerational precondition'; (ii) 'A growing smorgasbord of choices and requirements'; (iii) 'Parenthood becoming a project'; (iv) 'Stretched out life stages'; (v) '(Im)possibilities to procreate'; and (vi) 'Intergenerational pronatalism'. Our findings reflect increasing expectations on what it means to be prepared for parenthood. Despite increasing awareness of the precariousness of romantic relationships, people still wish to build new families but try to be as prepared as possible for adverse events. The findings also show how increasing life expectancy and medical advancements have come to influence people's views on their reproductive timeline.

Intergenerational Commensality: A Critical Discussion on Non-Familial Age Groups Eating Together

Connecting intergenerational relationships and commensality has been a neglected area in research and conceptual development within both food and life-course studies. This has been especially true of relations beyond the family. Here, public and private settings are explored in order to examine the relationship between eating together and generationally intelligent empathy. This is to help the discovery of spaces where different generations can interact positively around food and mealtimes. Contemporary social and public health challenges include: to adapt to increased longevity and to build solidarity between generations; to repair the relations between generations arising from institutional segregation; and to increase experiences of generational connection and social inclusion. As age-based cohorts are led to see themselves as separate from each other, we must find ways of building and negotiating new complementary roles for different parts of the life-course. Commensality, eating together at the same table provides an important cultural location and opportunity around which complementary understandings between generations may be built. A new framework is proposed to help identify and critically examine the variables underpinning non-familial intergenerational commensal spaces.

Generation Gaps in Digital Health Literacy and Their Impact on Health Information Seeking Behavior and Health Empowerment in Hungary

Background: Today the internet is a major source of health information, and younger generations have more confidence in their digital information seeking skills and awareness of online resources than older generations. Older generations, however, are more in demand of health services. The aim of our study was to explore these generational differences as related to self-perceived eHealth literacy and health care system utilization.

Methods: A cross-sectional survey study with 522 subjects was done in Hungary. Every subject belonged to one of four generations (Baby boomers, X, Y, and Z). The Web-based survey was designed and tested in English-speaking countries and translated into Hungarian for the present study. Variables include Internet health information seeking, eHealth literacy (measured by eHeals score), the self-perceived gain in empowerment by that information, and the number of health care appointments. One-way ANOVA was used for comparing the scores of the generations, and correlational and linear regression analysis was employed within the generations for further data analysis.

Results: We found significant differences among the generations in eHealth literacy as well as in the self-perceived gain in empowerment: while Boomers were the generation with the lowest eHeals scores, they showed the highest empowerment. Internet health information seeking behavior showed no differences. While subjects who use the Internet more frequently to search for health information have worse self-rated health status, the ones with higher eHeals scores report better subjective health status. We also identified the associations of the above variables within the older generations (Boomers and X) with the frequency of using health-care services: within the generation of Boomers the number of health care appointments was only associated with Internet health information seeking, while in Generation X with eHeals.

Conclusions: Baby boomers seek Internet health information as often as the younger generations, which provides a solid motivation for developing their eHealth literacy skills. We find it crucial to plan the Hungarian health promotion programmes utilizing this high frequency of Internet health information seeking, since the eHealth literacy skills of older generations have an effect on their subjective health status, and they are the most capable of applying information in making decisions.

Learning in virtual space: an intergenerational pilot project

Introduction: More and more educational institutions are discovering the advantages of settings for digital teaching and learning and the technology of virtual reality (VR). This also holds true for the BZ Pflege in the field of continuing education with age-heterogeneous groups of participants. The question arises whether baby-boomers and X and Y generation learners accept, understand and perceive the digital form of learning with VR glasses as beneficial for their learning.

Project description: A course has been developed with the goal of teaching the anatomy of the heart by immersive visualisation. A questionnaire was used to determine how the use of VR glasses influenced participants` learning, acceptance, understanding and cognitive load.

Results: The participants reacted positively to the VR technology. The new learning technology did not lead to cognitive overload. Participants indicated that they were able to link new knowledge with already existing knowledge. They also found the VR glasses easy to use.

Conclusion: From the perspective of participants and project management alike, it can be said that age- heterogeneous groups present no obstacle for new innovative teaching methods, such as the use of VR glasses.

Sulfonimide-Based Dendrimers: Progress in Synthesis, Characterization, and Potential Applications

There are more than 50 families of dendrimers, and some of which, such as polyamidoamine PAMAM, are well studied, and some are just starting to attract the attention of researchers. One promising type of dendrimers is sulfonimide-based dendrimers (SBDs). To date, SBDs are used in organic synthesis as starting reagents for the convergent synthesis of higher generations dendrimers, in materials science as alternative electrolyte solutions for fuel cells, and in medicinal chemistry as potential substances for drug transfer procedures. Despite the fact that most dendrimers are amorphous substances among the SBDs, several structures are distinguished that are prone to the formation of crystalline solids with melting points in the range of 120-250 °C. Similar to those of other dendrimers, the chemical and physical properties of SBDs depend on their outer shell, which is formed by functional groups. To date, SBDs decorated with end groups such as naphthyl, nitro, methyl, and methoxy have been successfully synthesized, and each of these groups gives the dendrimers specific properties. Analysis of the structure of SBD, their synthesis methods, and applications currently available in the literature reveals that these dendrimers have not yet been fully explored.

The Coming-Out Process in Family, Social, and Religious Contexts Among Young, Middle, and Older Italian LGBQ+ Adults

The coming out (CO) process is fundamental for identity integration among LGBQ+ people, and its impact can vary greatly depending on personal and contextual factors. The historical, cultural, and social contexts in which LGBQ+ people develop their sexual identity can mediate the relationship between CO and health outcomes. The present study aimed at clarifying the CO process in three generations of Italian LGBQ+ people (young adults: aged 20-40 years; middle adults: aged 41-60 years; older adults: aged 61-80 years) by providing data on: (a) sexual orientation milestones, such as age of first awareness, age of first self-label, and age of first CO, as well as the rate of disclosure during different life stages; (b) the rate and average age of CO to significant others; and (c) CO within the religious context and its effect on participants' minority stress experiences. A total of 266 Italian LGBQ+ people participated in the study, with ages ranging from 20 to 80 years (M = 41.15, SD = 16.13). Findings indicated that, on average, the older adult group became self-aware, self-labeled, and disclosed their sexual identity at a significantly older age than the other groups. Older adults were also more Catholic and had CO more frequently to their Catholic community, relative to young and middle adults. CO within the Catholic context was associated with distal and proximal minority stressors, such as discrimination, vigilance, and internalized sexual stigma. Catholic community reactions to participants' CO were distinguished through thematic analysis in three main types: unconditional acceptance, invitation to change, and open rejection. The present research extended current knowledge on CO and minority stress experiences in different generations of LGBQ+ people. Several differences emerged between generational groups on sexual orientation milestones, highlighting the potential impact of historical and cultural contexts in determining sexual minorities' experiences related to sexual identity. It is recommended that mental health professionals working with LGBQ+ clients implement targeted interventions based on their clients' multiple salient aspects, including age and religious background. Clinicians should also be aware of the potentially detrimental effects of CO within an unsupportive context, rather than encouraging CO tout court.

Long-lasting effects of antibiotics on bacterial communities of adult flies

Insect symbionts benefit their host and their study requires large spectrum antibiotic use like tetracycline to weaken or suppress symbiotic communities. While antibiotics have a negative impact on insect fitness, little is known about antibiotic effects on insect microbial communities and how long they last. We characterized the bacterial communities of adult cabbage root fly Delia radicum in a Wolbachia-free population and evaluated the effect of tetracycline treatment on these communities over several generations. Three D. radicum generations were used: the first- and second-generation flies either ingested tetracycline or not, while the third-generation flies were untreated but differed with their parents and/or grandparents that had or had not been treated. Fly bacterial communities were sequenced using a 16S rRNA gene. Tetracycline decreased fly bacterial diversity and induced modifications in both bacterial abundance and relative frequencies, still visible on untreated offspring whose parents and/or grandparents had been treated, therefore demonstrating long-lasting transgenerational effects on animal microbiomes after antibiotic treatment. Flies with an antibiotic history shared bacterial genera, potentially tetracycline resistant and heritable. Next, the transmission should be investigated by comparing several insect development stages and plant compartments to assess vertical and horizontal transmissions of D. radicum bacterial communities.

Consumers' Attitude towards the Sustainability of Different Food Categories

Currently, poverty, climate change, environmental pollution and the depletion of natural resources have generated a greater concern for sustainability. The objective is the survival of the human species and the persistence of all components of the biosphere. To achieve sustainability, human participation is essential; sustainable consumption depends on consumers’ perceptions of sustainability and how they affect their behavior. The aim of this study was to understand consumers’ perceptions and attitudes towards food sustainability based on country, age, gender, income and education level. An online survey was carried out in countries in Europe, America and Asia. Consumers were asked questions organized into food categories. The results showed that consumers’ attitude towards sustainability is understood differently in each country, even within the same food category. Consumers with lower education level showed the lowest knowledge and concern about food sustainability. Older generations were less aware of sustainability and its related problems. While income level presented unclear results, gender did not affect attitude towards food sustainability. Therefore, to achieve a sustainable future, raising awareness among the population is increasingly necessary. Consequently, segmenting training campaigns according to the group they are aimed at will provide a greater impact and, therefore, greater awareness.

Job Embeddedness: The Differences Between Registered Nurses and Healthcare Assistants

Retention of registered nurses (RNs) and health care assistants continue to be a challenge in acute care settings. This descriptive, comparative study examined differences of job embeddedness (JE) scores between RNs and health care assistants (HCAs) in acute care facilities. Generational differences for JE scores were also compared. A convenience sample of RNs and HCAs from medical and surgical units at two Texas hospitals completed the surveys. RNs valued community sacrifices significantly higher than HCAs. Total JE scores between baby boomers and millennials were significantly different, while organizational links scores among all three generations showed statistical significantly differences. Organizational fit, organizational sacrifice, and level of education added statistical significance to the prediction of job satisfaction.

Parenting Warmth and Strictness across Three Generations: Parenting Styles and Psychosocial Adjustment

Recent emergent research is seriously questioning whether parental strictness contributes to children’s psychosocial adjustment in all cultural contexts. We examined cross-generational differences in parental practices characterized by warmth and practices characterized by strictness, as well as the relationship between parenting styles (authoritative, indulgent, authoritarian, and neglectful) and psychosocial adjustment in adulthood. Parenting practices characterized by warmth (affection, reasoning, indifference, and detachment) and strictness (revoking privileges, verbal scolding, and physical punishment) were examined. Psychosocial adjustment was captured with multidimensional self-concept and well-being (life satisfaction and happiness). Participants were 871 individuals who were members of three generations of Spanish families: College students (G3), their parents (G2), and their grandparents (G1). Results showed two different cross-generational patterns in parenting practices, with an increased tendency toward parental warmth (parents use more affection and reasoning but less indifference across generations) and a decreased tendency toward parental strictness (parents use revoking privileges, verbal scolding, and physical punishment less across generations). Interestingly, despite cross-generational differences in parenting practices, a common pattern between parenting styles and psychosocial adjustment was found: indulgent parenting was related to equal or even better self-concept and well-being than authoritative parenting, whereas parenting characterized by non-warmth (authoritarian and neglectful) was related to poor scores.

Audiovisual Media Communications in Adult Education: The case of Cyprus and Greece of Adults as Adult Learners

Nowadays, audiovisual media technologies and audiovisual content (audiovisual media communications) play an important role in our physical/psychological health, education, and lifelong learning, causing the redefinition of the teaching methodology. As presented in the literature, the use of audiovisual media communications presuppose a new way of approaching effective teaching, which requires the educators on all educational levels and disciplines to display with competence many advanced skills and abilities. The aim of this research is to provide data that will contribute to the effective teaching utilizing audiovisual media communications in adult education. This research is a secondary research from two researches, which are qualitative and based on a quantitative method of analyzing. The primary data were collected through experiment method from adults (18 years and older), in Cyprus and Greece. The results confirm the current debate of using audiovisual media technologies within the educational process in technology-enhanced learning in education, both from the literature, and from the findings and results of various researches. This research is part of a larger, ongoing research that explores the multidisciplinary field that incorporates media, audiovisual content, and education (MACE), information and communications technologies (ICTs) in adult education (in Greece and Cyprus).

Meaning-Making of War Experiences: Stories From Kosova

The research evidence shows that war had many detrimental effects on the mental health, wellbeing, and social functioning of the people of Kosova, which is similar to the findings in many other postconflict societies. However, there are few studies focusing on the process of meaning-making of war experiences and their impacts on resilience and growth. This phenomenological study aimed to explore the lived war experiences of citizens of Kosova from the perspectives of three generations (grandparents, parents and children) through semistructured interviews, which were conducted with 37 participants. Thematic analysis revealed that the journey of the meaning-making of war experiences in Kosova is rather dynamic and reflects the context in which each generational cohort lived and grew. The findings provide a deeper understanding of the strategies used by each generation for meaning-making and how these strategies contributed to resilience and growth. The implications for mental health counselors, social workers, and policymakers are discussed.

The gendered relationship with drunkenness among different generations in Mediterranean and Nordic countries

The study adopts a qualitative comparative approach to better understand how different dimensions affect social norms regulating alcohol consumption. Female and male attitudes towards drunkenness were analysed on the basis of data from 27 focus groups involving a total of 166 participants from Italy, Finland and Sweden, grouped by age cohort (17–20 and 50–65 years) and educational level. Results suggest that gendered drinking norms may be affected more by the drinking culture than by the degree of gender equality, thus providing a possible explanation of why gender differences in drinking are not always consistent with broader gender inequalities.

On the future of the individual longitudinal age-crime curve

BACKGROUND

This article serves as our memorial for the outstanding contribution of Rolf Loeber to developmental criminology. His salient paper on the future of the study of the age-crime curve (2012) is the focal point.

AIMS

Follow some research trails that Rolf Loeber proposed in his 2012 paper.

METHODS

Recent data on official offending from the Montréal Two Samples Four Generations Cross-sectional and Longitudinal Studies (MTSFGCLS) are analysed. The data were gathered for two generations of juvenile court males; five birth cohorts born around 1960 and followed from age 8 to 61, and five birth cohorts born around 1980, males and females traced from age 12 to 45. The age-crime curves are presented for the total prevalence. Epidemiological data are displayed for career descriptors: number of years active in offending, frequency, variety, onset, offset and duration.

RESULTS

The age-crime curves of the two generations display the habitual shape reported in the literature. The epidemiological data shows that the population sample has a much lower curve in comparison to the court sample; this sort of difference is also observed between females and males.

CONCLUSION

The difference between the two generations in the age-crime curves are interpreted in light of three evolutions in Québec from 1960 to 2000: (a) a radical change in the delinquency law, social and criminal justice policies, and treatment for juvenile delinquents; (b) a reduction of the juvenile and adult crime rates; (c) a significant increase in the wellbeing of the population on education, health and welfare services.

The association between religiosity and pregnancy acceptability among Latino/a young adults: does generational status matter?

The US Latino/a population is considered to be at high risk for unintended pregnancy; some research indicates that Latino/a parents are more likely to express happiness about an unintended pregnancy than other racial/ethnic groups. Associations between pregnancy attitudes and factors such as religiosity and nativity have also been documented in the Latino/a population, but existing research is sparse, dated and primarily focused on women of Mexican heritage. This study sought to expand this literature by examining the relationship between religiosity and pregnancy acceptability and assessing effect modification by generational status and gender in a national sample of young Latino/a cisgender women and men of various ancestral backgrounds currently in relationships. In multivariable logistic regression models, there was a positive association between importance of religion and pregnancy acceptability for both men and women; being highly or moderately religious was associated with elevated odds of finding a pregnancy acceptable. Effect modification by generational status was significant for women, but not for men. Results suggest that religiosity, gender and generational status have differential influences on and relationships to pregnancy orientations for Latina women and Latino men and should be considered in the design and delivery of family planning care for Latino/a clients.

Dynamics of genomic architecture during composite breed development in cattle

Some livestock breeds face the challenge of reduced genetic variation, increased inbreeding depression owing to genetic drift and selection. Hybridization can reverse these processes and increase levels of productivity and adaptation to various environmental stressors. Samples from American Brangus were used to evaluate the indicine/taurine composition through nine generations (~45 years) after the hybridization process was completed. The purpose was to determine how hybridization alters allelic combinations of a breed over time when genetic factors such as selection and drift are operating. Furthermore, we explored genomic regions with deviations from the expected composition from the progenitor breeds and related these regions to traits under selection. The Brangus composition deviated from the theoretical expectation, defined by the breed association, of 62.5% taurine, showing taurine composition to be 70.4 ± 0.6%. Taurine and indicine proportion were not consistent across chromosomes. Furthermore, these non‐uniform areas were found to be associated with traits that were probably under selection such as intermuscular fat and average daily gain. Interestingly, the sex chromosomes were predominantly taurine, which could be due to the composite being formed particularly in the final cross that resulted in progeny designated as purebred Brangus. This work demonstrated the process of new breed formation on a genomic level. It suggests that factors like genetic drift, selection and complementarity shift the genetic architecture into a uniquely different population. These findings are important to better understand how hybridization and crossbreeding systems shape the genetic architecture of composite populations.

Zirconia and its novel compositions: What do clinicians need to know?

For several years, there has been a clear trend in the dental market towards monolithic tooth-colored restorations. In this context, further developments, particularly in the field of zirconia ceramics, have led to considerable improvement in the materials' optical properties. Modern zirconia materials can be divided into several cohorts, differing from each other with respect to their optical and mechanical properties. The knowledge about indications and limitations of each zirconia cohort is essential for a correct clinical application. Clinical long-term experience for the zirconia of the newest generations is still scarce and only in-vitro data are available. Despite all advancements, clinical long-term success remains closely linked to the specific indications, preparation, material selection, knowledge, and experience of the dental practitioner and dental technician, as well as an adequate luting mode and occlusal concept. Due to the high innovation rate within materials and CAD/CAM technology in general, clinicians and dental technicians need to be well informed in order to be able to work successfully with the various options.

A study of Genomic Prediction across Generations of Two Korean Pig Populations

Simple Summary

Commercial genotyping has become accessible at a relatively low cost and nowadays it is widely used by breeders to predict production and economic traits. Many studies explored the benefits of using DNA information in breeding programs, and many methods have been established to optimize the use of such information. To date, however, very few studies have explored how prediction accuracies change across generations. Here we present a short evaluation across five generations in two pig breeds and evaluate the accuracy of the prediction of relevant production traits using different generational groups.

Abstract

Genomic models that incorporate dense marker information have been widely used for predicting genomic breeding values since they were first introduced, and it is known that the relationship between individuals in the reference population and selection candidates affects the prediction accuracy. When genomic evaluation is performed over generations of the same population, prediction accuracy is expected to decay if the reference population is not updated. Therefore, the reference population must be updated in each generation, but little is known about the optimal way to do it. This study presents an empirical assessment of the prediction accuracy of genomic breeding values of production traits, across five generations in two Korean pig breeds. We verified the decay in prediction accuracy over time when the reference population was not updated. Additionally we compared the prediction accuracy using only the previous generation as the reference population, as opposed to using all previous generations as the reference population. Overall, the results suggested that, although there is a clear need to continuously update the reference population, it may not be necessary to keep all ancestral genotypes. Finally, comprehending how the accuracy of genomic prediction evolves over generations within a population adds relevant information to improve the performance of genomic selection.

Exploring intergenerational differences in burnout and how they relate to work engagement, norms, and values: a mixed-methods study

BACKGROUND

Burnout has been on the rise in recent years. Is this increasing prevalence due to changing working circumstances, or also to a changing societal context?

AIM

The aim of the study was to explore intergenerational differences in burnout.

DESIGN & SETTING

The study used a mixed quantitative and qualitative design, and tested the theory of the job demands-resources model (JD-RM). The target group of this research was the working population in Belgium, aged between 21-65 years. The study was performed in a public setting with people recruited through social media.

METHOD

A quantitative web survey was distributed among the participants to explore the prevalence of burnout, work ethic, work engagement, and norms and values. The second part of the study used a focus group technique to explore in depth the eight statements that were formulated from the quantitative survey.

RESULTS

A total of 309 people participated in the web survey and 21.5% met the criteria for 'burnout', while 22.6% scored high on the criteria for 'engagement'. It was found that 12.6% of all men and 3.0% of all women could not identify with the portrait of 'equivalence'. The value 'benevolence' was positively rated by 100%. In the youngest generation, 71.3 % identified with the portrait of 'stimulation', while 70.8% of older men identified with the portrait 'traditions'. The results also revealed that 43.1% of the younger generation agreed with the statement: 'I often think I would be more successful if I gave up certain pleasures' CONCLUSION: Burnout is more common among young people. In the older generation, a good ability to put things into perspective, a good balance between work and leisure, and a strong sense of tradition appear to be resources to aid against burnout. The younger generation often deals with stressors. This younger generation appears to have a higher work ethic and commitment.

Collective Memory from a Psychological Perspective

Social scientists have studied collective memory for almost a century, but psychological analyses have only recently emerged. Although no singular approach to the psychological study of collective memory exists, research has largely: (i) explored the social representations of history, including generational differences; (ii) probed for the underlying cognitive processes leading to the formation of collective memories, adopting either a top-down or bottom-up approach; and (iii) explored how people live in history and transmit personal memories of historical importance across generations. Here, we discuss these different approaches and highlight commonalities and connections between them.

Materials for Photovoltaics: State of Art and Recent Developments

In recent years, photovoltaic cell technology has grown extraordinarily as a sustainable source of energy, as a consequence of the increasing concern over the impact of fossil fuel-based energy on global warming and climate change. The different photovoltaic cells developed up to date can be classified into four main categories called generations (GEN), and the current market is mainly covered by the first two GEN. The 1GEN (mono or polycrystalline silicon cells and gallium arsenide) comprises well-known medium/low cost technologies that lead to moderate yields. The 2GEN (thin-film technologies) includes devices that have lower efficiency albeit are cheaper to manufacture. The 3GEN presents the use of novel materials, as well as a great variability of designs, and comprises expensive but very efficient cells. The 4GEN, also known as "inorganics-in-organics", combines the low cost/flexibility of polymer thin films with the stability of novel inorganic nanostructures (i.e., metal nanoparticles and metal oxides) with organic-based nanomaterials (i.e., carbon nanotubes, graphene and its derivatives), and are currently under investigation. The main goal of this review is to show the current state of art on photovoltaic cell technology in terms of the materials used for the manufacture, efficiency and production costs. A comprehensive comparative analysis of the four generations is performed, including the device architectures, their advantages and limitations. Special emphasis is placed on the 4GEN, where the diverse roles of the organic and nano-components are discussed. Finally, conclusions and future perspectives are summarized.
