Understanding the role of corporate social responsibility and sustainable supply chain management in shaping the consumers’ intention to use sharing platforms

Sustainable supply chain management (SSCM) in sharing economy platforms supports resource management and achieves environmental sustainability. Corporate social responsibility (CSR) is an essential pillar of sustainability, but the link between CSR and SSCM has been missing in the literature. Therefore, the current study intends to examine the connection between CSR and SSCM practices in sharing economy-based platforms. This study has applied the means-end theory to understand customer intention in the sharing economy. The data of 379 respondents from five main cities of Pakistan have been collected through convenience sampling. Partial least square structural equation modeling (PLS-SEM) has been used to test the proposed conceptual model. The study results show that the corporate social responsibility approach adopted by the sharing economy platforms improves internal supply chain management that drives customers’ intention to use sharing economy platforms. Green concern has a significant moderating effect on customers’ tendency toward environmental issues and solutions. However, findings revealed that eco-design in the sustainable supply chain does not affect customer purchase intention in sharing economy platforms. The study findings provide practical implications to organizations focusing on sustainable supply chain management practices in the sharing economy.

Modeling teachers acceptance of learning management system in higher education during COVID-19 pandemic: A developing country perspective

The ubiquity of the World Wide Web has provided massive opportunities to teachers and learners around the globe to share knowledge anytime anywhere via learning management system. Hence, considering the needs of the students; universities have arranged the facilities of the learning management system. This study is an empirical evaluation of university faculty members' intention to use a learning management system. We extended Davis's (1989) Technology Acceptance Model (TAM) to evaluate faculty members' intention to use learning management system amid COVID-19. Data were obtained from the faculty members of Pakistani universities through the convenience sampling technique and analyzed using PLS-SEM. The outcomes of the study revealed that perceived ease of using a learning management system, user-interface design, and faculty members' innovativeness have a favorable impact on their intention to use learning management system. Facilitating conditions positively influenced intention to use learning management system. However, the positive relationship between facilitating conditions and perceived ease of using the learning management system was insignificant. The results indicate that the extended TAM model has effectively predicted faculty members' intention to use the learning management system. The findings of the current study can be used for the training and development of faculty members by institutions and regulatory bodies in developing countries.

Predicting household sign up for solar energy: an empirical study based on the extended theory of planned behavior

Purpose

This study aims to understand households’ adoption of small-scale solar energy to reduce carbon dioxide emissions that cause due to conventional energy consumptions.

Design/methodology/approach

This study is quantitative in nature and households were selected as unit of analysis. Online data has been collected from seven main cities of Pakistan to understand households’ intention to use small-scale solar energy for domestic consumption. A total of 370 valid data were analyzed through partial least square structural equation modeling.

Findings

The study findings reveal that publicity information, attitude green norm and perceived behavioral control are the strongest predictors of households’ intention to use small-scale solar energy.

Practical implications

The considered model practically contributes to the literature by understanding households’ intention to adopt solar technologies that are viable means to conserve conventional energy and preserve the environment through less emission of carbon dioxide. In addition to this, understanding the green norm of households is imperative in a developing country, Pakistan where climate risk is high. Understanding household’ green norms would help marketers and practitioners to design and introduce new and more efficient renewable technologies that maintain environmental sustainability.

Originality/value

This study has contributed to theory of planned behavior (TPB) by the inclusion of publicity information and green norms. Previous studies focused on the environmental benefits of using renewable energy sources. This study added novel antecedents into TPB that help to understand the adoption of small-scale solar energy for domestic consumption.

A Serial-Mediation Model to Link Entrepreneurship Education and Green Entrepreneurial Behavior: Application of Resource-Based View and Flow Theory

Eco-conscious behaviors have become a global imperative for entrepreneurs, as the consumer demand for products and services has become increasingly green. Hence, the purpose of this study is to identify the role of entrepreneurship education in environmental sustainability as measured by the launch of green ventures. This study also aims at extending the literature of resource-based view and flow theory by highlighting their application into the green venturing context. Data were collected from 420 Pakistani students having studied an entrepreneurship course in their university life by using the convenience sampling technique. The covariance based structural equation modeling (CB-SEM) was used to test the hypothesized relationships, and it was identified that entrepreneurship education evokes commitment to the environment, subsequently leading towards university green entrepreneurial support, environmental motivation, and green entrepreneurial behavior. University green entrepreneurial support also significantly influences green venturing; however, environmental motivation does not affect green entrepreneurial behavior. The findings of this study can be useful for policymakers in higher educational institutions, regulatory bodies, and diverse-government agencies dealing with UN sustainable development goals.

An empirical study of purchase intention of energy-efficient home appliances: the influence of knowledge of eco-labels and psychographic variables

Purpose

The purpose of this study is to empirically evaluate the antecedents of consumers’ purchase intention of energy-efficient home appliances.

Design/methodology/approach

A self-administered questionnaire has been used to gather data from the targeted representatives of the population. Quota based on age and convenience sampling techniques were used to select the participants of the study, as it is a suitable technique in situations where the possibility of getting a complete sampling frame is difficult. More than 73% of the population of Pakistan is aged below 34 years (Pakistan Bureau of Statistics, 2017). Based on this information, the current study has allocated more than 75% quota to consumers who are below 35 years.

Findings

The findings of the study reveal that all antecedents have significant impact on consumers’ purchase intention of energy-efficient home appliances. Environmental concern, green trust and products’ functional values are most influencing factors in the purchase of energy-efficient home appliances.

Originality/value

This study is related to energy-efficient home appliances in Pakistan. Systematic literature suggested the need to analyze the antecedents of energy-efficient appliances. This study helps the practitioners and marketers to understand consumers’ behavior regarding the purchase of energy-efficient home appliances.

An empirical study of consumers intention to purchase energy efficient appliances

Purpose

The purpose of this study is to develop a theoretical framework of consumers’ purchase intention of energy efficient home appliances.

Design/methodology/approach

Non-probability quota based on age and education and purposive sampling technique have been used to assess data collected by a questionnaire survey.

Findings

The findings of the study reveal that consumers’ knowledge of eco-labels, environmental concern and perceived consumer effectiveness are the important predictors of purchase intention. However, the positive relationship between green trust and products’ functional value was found insignificant. It is believed that consumers’ are skeptical about products’ functional benefits.

Research limitations/implications

Although this study has presented a holistic approach to assess consumer purchase intention for energy-efficient home appliances, there are some limitations of the current study. First, this study has focused on consumer intention to purchase energy-efficient home appliances rather than actual purchase of appliances. Ajzen (1991) argued that intention is the accurate and immediate measure of actual, but gaps exist between intention and the actual behavior of the consumers (Ajzen and Fishbein, 1980). Consumers’ intentions may not always result in actual behavior. Thus, to expand research applicability, researchers should include actual behavior of consumers by conducting interviews or collecting data from the same consumers after an interval of three to six months. Second, the study has focused on consumers’ psychographic variables, there may be many other factors such as technological variables, government and pressure group influence and media impact on consumer intention to purchase energy-efficient home appliances. Future studies can integrate the impact of these potential variables on consumer purchase intention of energy-efficient home appliances with the same model. The third limitation is related to the methodology of this study, the quantitative method has been used in this study. Future studies may use qualitative and mixed methods to better understand consumers’ inclination of purchase intention of energy-efficient home appliances in Pakistan. Besides, a qualitative study will be helpful to explore new variables that are essential in the decision-making of consumers for the purchase of energy-efficient home appliances in Pakistan. Pakistan is a developing country where the majority of the people are belonging to the middle-class; there may be many other important factors that affect consumers’ purchase intention of energy-efficient home appliances. Therefore, an in-depth qualitative study would be helpful to explore those variables in the context of a developing country.

Practical implications

Energy consumption has posed serious threats to the sustainability of the environment and endangered the lives of many species across the globe. Environmental degradation due to unsustainable consumptions has provided ample opportunities to the marketers that led to the development of sustainable products such as energy-efficient home appliances. In this study, the antecedent of purchase intention of energy-efficient appliances includes attitude, functional values, perceived consumer effectiveness, consumers’ knowledge of eco-labels, environmental concern and green trust. Although researchers have extended TBP to predict consumers’ purchase intention of energy-efficient appliances, studies lack to provide a holistic view from consumers’ perspective. Consumers’ concern for the safety of the environment depicts consumers tendency to purchase environmentally friendly products and promote less hazardous products. Marketers should incorporate environmentally friendly benefits to the product that serve to attract maximum consumers and maintain harmony with the environment. Consumers’ knowledge of eco-labels, green trust and functional values are a vital construct that needs focus in term of the energy-efficient appliances purchase decision. Eco-labels are one of the emerging marketing tools that serve to guide consumers related to products environmentally friendly attributes and contribute to the acceptability of products. Marketers can use eco-labels to differentiate green products from conventional and establishes consumers’ trust in product performance.

Originality/value

This study is relevant to energy-efficient home appliances. Systematic literature of previous studies suggested the need to conduct and examine the antecedents of energy-efficient home appliances in developing markets. This research highlights that perceived consumer effectiveness is the most influencing factor affecting intention. The implications of this study would be helpful in understanding consumers’ behavior toward the purchase of green products in developing markets.

Predicting eco-conscious consumer behavior using theory of planned behavior in Pakistan

Sustainability of the environment has become pivotal in the modern world, and there have been enormous efforts by the world leaders and organizations to reduce the effects of hazardous production on the environment. This has led companies to implement pro-environment programs and work on sustainability to shift consumption from conventional products to green products. This study incorporates green trust, environmental concerns, and intrinsic religious orientation as a moderator into the theory of planned behavior. It aims to validate the theory of planned behavior and its extended form to predict Pakistani consumers' eco-conscious behavior, and simultaneously assess the moderating effect of intrinsic religious orientation on consumers' attitude towards green products. The data for the study was collected from 300 respondents through purposive sampling from Karachi, the metropolitan city of Pakistan. Structural equation model (SEM) was applied to test the proposed hypotheses. The results of SEM indicate that all paths in the model are significant, except the path from attitude towards green products to eco-conscious behavior. The results also indicate that intrinsic religious orientation has no moderating effect on the green trust and attitude towards green products. This study contributes to understand the effects of new constructs in the theory of planned behavior and their relationship with other variables in the model. It also provides theoretical and managerial implications to academics and marketing professionals for understanding and promoting eco-conscious consumer behavior.

Use of Mechanical Circulatory Support in Patients Undergoing Percutaneous Coronary Intervention

Background—

Little is known about the contemporary use of intra-aortic balloon pump (IABP) and other mechanical circulatory support (O-MCS) devices in patients undergoing percutaneous coronary intervention (PCI) in the setting of cardiogenic shock.

Methods and Results—

We identified 76 474 patients who underwent PCI in the setting of cardiogenic shock at one of 1429 National Cardiovascular Data Registry CathPCI participating hospitals from 2009 to 2013. Temporal trends and hospital-level variation in the use of IABP and O-MCS were evaluated. No mechanical circulatory support was used in 41 286 (54%) patients, 29 730 (39%) received IABP only, 2711 (3.5%) received O-MCS only, and 2747 (3.6%) received both IABP and O-MCS. At the start of the study period, 45% of patients undergoing PCI in the setting of cardiogenic shock received an IABP and 6.7% received O-MCS. The proportion of patients receiving IABP declined at an average rate of 0.3% per quarter, whereas the rate of O-MCS use was unchanged over the study period. The predicted probability of IABP use varied significantly by site (hospital median 42%, interquartile range 33% to 51%, range 8% to 85%). The probability of O-MCS use was <5% for half of hospitals and >20% in less than one-tenth of hospitals.

Conclusions—

In this large national registry, the use of IABP in the setting of PCI for cardiogenic shock decreased over time without a concurrent increase in O-MCS use. The probability of IABP and O-MCS use varied across hospitals, and the use of O-MCS was clustered at a small number of hospitals.

Grave's disease associated with immunoglobulin A nephropathy: A rare association

Immunoglobulin A (Ig A) nephropathy is the most common form of primary glomerulonephritis. The association of Ig A nephropathy with Grave's disease has not been reported so far. We report a case of 20-year-old female with Grave's disease who presented with edema, facial puffiness, and decreased urine output. She was found to be hypertensive with renal failure and nephrotic range proteinuria. Renal biopsy revealed features of Ig A nephropathy. The patient was treated with oral corticosteroids (1 mg/kg/day). To our knowledge, this is the first case showing association of Grave's disease with Ig A nephropathy.

Safety and efficacy of thrombectomy in patients undergoing primary percutaneous coronary intervention for acute ST elevation MI: a meta-analysis of randomized controlled trials

BACKGROUND

Clinical trials comparing thrombectomy devices with conventional percutaneous coronary interventions (PCI) in patients with acute ST elevation myocardial infarction (STEMI) have produced conflicting results. The objective of our study was to systematically evaluate currently available data comparing thrombectomy followed by PCI with conventional PCI alone in patients with acute STEMI.

METHODS

Seventeen randomized trials (n = 3,909 patients) of thrombectomy versus PCI were included in this meta-analysis. We calculated the summary odds ratios for mortality, stroke, post procedural myocardial blush grade (MBG), thrombolysis in myocardial infarction (TIMI) grade flow, and post procedural ST segment resolution (STR) using random-effects and fixed-effects models.

RESULTS

There was no difference in risk of 30-day mortality (44/1914 vs. 50/1907, OR 0.84, 95% CI 0.54-1.29, P = 0.42) among patients randomized to thrombectomy, compared with conventional PCI. Thrombectomy was associated with a significantly greater likelihood of TIMI 3 flow (1616/1826 vs. 1533/1806, OR 1.41, P = 0.007), MBG 3 (730/1526 vs. 486/1513, OR 2.42, P < 0.001), STR (923/1500 vs. 715/1494, OR 2.30, P < 0.001), and with a higher risk of stroke (14/1403 vs. 3/1413, OR 2.88, 95% CI 1.06-7.85, P = 0.04). Outcomes differed significantly between different device classes with a trend towards lower mortality with manual aspiration thrombectomy (MAT) (21/949 vs.36/953, OR 0.59, 95% CI 0.35-1.01, P = 0.05), whereas mechanical devices showed a trend towards higher mortality (20/416 vs.10/418, OR 2.07, 95% CI 0.95-4.48, P = 0.07).

CONCLUSIONS

Thrombectomy devices appear to improve markers of myocardial perfusion in patients undergoing primary PCI, with no difference in overall 30-day mortality but an increased likelihood of stroke. The clinical benefits of thrombectomy appear to be influenced by the device type with a trend towards survival benefit with MAT and worsening outcome with mechanical devices.

Mucormycosis in patients with complicated cirrhosis

INTRODUCTION

Rhino-orbito-cerebral mucormycosis is a rapidly progressive and fatal disease that mostly occurs in patients with diabetes mellitus and immunocompromised status. Antifungal therapy with surgical debridement is the standard of care. Patients with cirrhosis of liver are more prone to develop different infections. Many of these also show glucose intolerance or frank diabetes mellitus. Little is known about the clinical presentation and outcome of mucormycosis in patients with cirrhosis. Treatment is difficult due to underlying coagulopathy and hepatic dysfunction.

METHODS

Medical records of the past five years were searched for the cirrhotic patients admitted with associated diagnosis of mucormycosis or fungal infection. Six patients with mucormycosis were identified.

RESULTS

Out of six patients, five were male. Age range was 15-57 years. Cause of cirrhosis was hepatitis C in four patients, hepatitis B in one patient and autoimmune hepatitis in one patient. Two patients had hepatocellular carcinoma. Four patients had diabetes mellitus, of which one patient was also on steroids for the autoimmune liver disease. Four patients had spontaneous bacterial peritonitis at the time of admission. All six patients presented with rhino-orbitocerebral mucormycosis with nasal discharge and upper motor neuron signs. Diagnosis of mucormycosis was made by culture of biopsy and scrapings taken from the palate and nasal sinuses. These patients received amphotericin B. Four patients died while in the hospital, while two patients died within next few days after discharge.

CONCLUSION

Mucormycosis in cirrhosis is not very common and has a poor prognosis. Patients with advanced cirrhosis and diabetes mellitus are at risk of developing infection.
