This paper aims to explore the effects of bank diversification (i.e. diversification of income and diversification of assets) on Bangladeshi banks’ profitability.

Using a dynamic panel data model with system generalized methods of moments, the authors examine an unbalanced panel data from 32 banks spanning 318 bank-year observations from 2007 to 2016.

The findings indicate a significant positive association of income diversification and asset diversification on bank profitability. Therefore, the results show that banks can generate profit from diversification of income and diversification of assets.

One of the rare attempts to investigate the relationship between diversification and profitability in Bangladesh’s banking sector is this report. The authors anticipate the results to have major consequences for Bangladeshi bank regulators and other related economies.

Presents the manipulation methods of a low powered direct‐drive robot‐arm for heavy object manipulation using a suspension device. Considers manipulation of a suspended tool in the horizontal plane. Presents the algorithm of the hybrid position/force tracking scheme with respect to the dynamic behavior of suspended tools in the horizontal plane. To manipulate the suspended robot‐arm vertically, the hybrid position/force dynamic model has been developed by considering the gravity compensation of the spring balancer. In order to show the possible industrial applications chamfering operations have been carried out. Simulations and experiments demonstrate the feasibility of the proposed systems.

Although corporate social responsibility is a well-researched concept, very few studies have studied organizational social responsibility in the face of internal/external crises. Therefore, this paper aims to examine various firms' organizational social responses to COVID-19 as an external crisis, particularly in terms of the way organizations use their resources to address social problems and the real intention behind these, and the changing organizational drivers influencing such behaviors.

The authors explore the initiatives of seven organizations from three different industries in several countries and their actions in the wake of the COVID-19 pandemic. A case study approach was taken to collect data and reach a conclusion. A combination of interviews, online communication using semi-structured questionnaires and documentary information available in the public domain was used to collect data and analyze and triangulate the events.

Similar internal resources and capacities of the seven organizations resulted in similar responses as they launched proactive initiatives to prepare sanitizers. This research indicates that these organizations pursued other goals besides economic one. When society needed help, these organizations responded quickly, using and reorganizing their resources to assist communities in need. Different organizations from different sectors all behaved in a similar manner, making genuine contributions to the pandemic as each was uniquely capable of doing. These organizations also used their unique capabilities to offer their resources to local communities and governments.

During the COVID-19 pandemic, efforts by corporate entities to facilitate social reform and recovery have been seen around the globe. The findings could help in understanding the responses of organizations engaging in socially responsible behaviors to overcome external crises. This paper also identifies changing organizational values and their possible impact on society and overall industry philanthropy practices in the future.

COVID-19 pandemic has significantly impacted the lives of people and businesses around the world in different ways. France, Spain, Italy and the UK are among the worst affected countries by this pandemic. The purpose of this paper is to identify and compare different corporate social responsibility (CSR) activities taken by the clubs and player of the major football leagues of these four countries to develop a more comprehensive model of intervention.

This paper has analyzed the initiatives taken by these football clubs and players to address financial vulnerabilities, mental health problems and domestic violence among the stakeholders and compared them with the existing CSR and humanitarian models. A case study approach has been used to collect and analyze data related to the CSR activities taken by the players and club management. Official websites of the clubs, newspaper and journal articles were among the major sources used to collect data for the paper.

Football clubs and players of the four major leagues have raised funds through different campaigns and delivered foods and essential medical supplies to the communities and hospitals to address financial vulnerabilities, mental health issues and domestic violence within their communities during the COVID-19 pandemic. They have provided guidance to their followers using social and television media to improve their physical and mental health during the pandemic. Online competitions, quizzes or virtual hangouts have also been used by the players to engage the stakeholders on a frequent basis. Football clubs have also initiated campaigns to raise awareness within the community on available medical services for the victims of domestic violence and also provided them with shelter, food, medical, legal and online counseling services.

Football clubs and players of the major leagues were always at the forefront to help the communities and hospitals to address issues related to mental health problems, financial vulnerabilities and domestic violence during the COVID-19 pandemic. The findings of this paper could help and guide other entities in designing a more comprehensive model of CSR interventions during pandemics or crisis situations to address financial vulnerabilities, mental health problems and domestic violence within their communities.

The issue of empty truck trips is largely ignored in the current literature. In order to cover this important research gap, the purpose of this paper is to explore, describe, categorize and rank the potential truck-sharing constraints for container trucks traveling empty around the port gates.

In order to contribute empirically to the current body of knowledge and understandings of truck-sharing constraints, this paper adopts a multi-method empirical approach involving both qualitative interviews and quantitative questionnaire surveys.

Among many key constraints that influence the future of truck-sharing opportunities, the authors determine, for example, that a carrier’s ability to earn the trust of its competitors is one of the top most important factors of success for a fruitful truck-sharing event. The problem is, perhaps, further complicated because of the increasing competitive environment in the container transport industry, as well as the lack of effective coordination between the key parties involved.

None of the earlier studies has provided a broad understanding and ranking of the truck-sharing constraints that should be considered in truck-sharing events, although the empty trips issue has been limitedly mentioned in the recent academic literature.

Empty truck trips are wasted miles. Wasted empty miles decrease transport capacity in the container distribution chain along with causing an increase in carbon emission, traffic congestion, fuel consumption and environmental pollution. The research results can be used by policy makers to underpin effective measures to prevent the low utilization of trucks.

This study addresses an important gap. To the authors’ knowledge, this is the first study in the area that ranks truck-sharing constraints to reduce empty trucks trips.

Maternal mortality is an acute problem for many countries around the world, particularly those at the bottom of the pyramid (BoP). Most remote locations in these underdeveloped nations, for instance, in Africa, have to cope with the problem of interrupted electricity supply making healthcare practitioners often experience a helpless compulsion to compromise in providing quality medical attention, especially during childbirth. Along with many public, private and nongovernment initiatives, WE CARE Solar (hereafter WCS) – a social innovation venture comes with an idea of developing portable solar suitcases to respond to this intransigent problem.

This paper introduces a social enterprise that established its operation in Africa and so far has served in more than 30 similarly impoverished economies. Data was collected, analyzed using documentary research method. The authors have also collected and correlated the statements from the founder of WCS to complement the authors’ findings. With this paper, the authors intend to establish the type of innovation tools that are needed to provide value with a social innovation initiative in the health sector in the least developed country perspective. To facilitate better social outcomes and to ensure greater good, innovation requires to be accompanied by stakeholders’ involvement.

The findings indicate that WE CARE Solar has a positive social contribution toward ensuring safe motherhood and childbirth in underdeveloped countries by providing access to reliable solar power sources. The six-step social innovation process can be adopted by other social ventures to propose innovative solutions to social needs. Analyzing WCS's service delivery from the perspective of the 4As framework and value co-creation model, it is suggested that sustainable social change can be established with value co-creation through community engagement with multiple stakeholders.

This research was solely focused on one organization alone. Future research could look into the model to ascertain its acceptability in similar social innovation in healthcare initiatives.

This paper attempts to address a gap in social innovation in healthcare and its adaptability using the 4As framework with the value co-creation model. The authors propose this model from the data accumulated throughout the research, which could also serve to assist organizations looking for scalable and sustainable change.

A seaport is an essential part of a supply chain, but many ports experience truck shortages, creating pressure for port authorities from shippers who need more trucks that move cargo. This study explores and ranks the motives for adopting a truck-sharing concept (where shippers share the same truck for delivery) as a mechanism to improve transport capacity.

This study adopts a multi-method approach – both interviews and surveys. Interviews are first conducted with shippers to explore truck-sharing usage motives. Next, quantitative surveys of both shippers and carriers are conducted to rank those motives.

The study identifies five motives (operational efficiency goal, quick transport solution, sustainability policy, convenience-seeking behavior and secure transport process) for truck-sharing, four critical transport attributes (lower charges for freight, distance travelled, full capacity utilization and environmental recognition), four psychological consequences (monetary savings, greater safety, instant availability of trips and clarification of environmental values), and six core values (secure transport process, being careful of money, ease of doing business, sustainability, status in the community and recognition by customers of shippers).

The qualitative results will help researchers better understand how usage motives influence shippers' willingness to share a truck for transport needs. The quantitative results are useful for ranking truck-sharing motives by their importance.

Based on the findings, managers of carriers can categorize shippers according to their specific needs and thereby customize promotions to attract more shippers.

The findings provide the first, exploratory insights into shippers' motives.
