With the increase of social media usage in the workplace as a background, this paper specifically addresses social media efficacy's and social media privacy's impact on supervisor and subordinate trust, affective organizational commitment (AOC) and organizational citizenship behavior (OCB) through the theoretical lens of communication privacy management (CPM) theory.

An online survey of 337 full- and part-time workers was conducted.

Path models showed that social media efficacy positively influenced social media privacy which in turn impacted both supervisor trust and subordinate trust. Supervisor trust was positively related to AOC, while subordinate trust positively influenced OCB. t-tests revealed differences between workers who have social media relationships with supervisors and/or subordinates and those workers without such relationships.

If workers believe they are adept at using social media, they will also be less concerned about the company's ability to infringe upon privacy through unwanted access to social media content. If social media efficacy drives perceptions of social media privacy and indirectly influences trust and organizational outcomes then it may be worthwhile for organizations to help enhance workers' feelings of social media efficacy through professional development programs.

This study is the first to extend research on workplace communication privacy into the realm of social media. Social media relationships also influence the work environment. These findings can be used as information in future research as well as policy development and professional development programs.

We show that, in the US telecommunications industry, market participants have a sophisticated understanding of the political process, and behave strategically in their allocation of contributions to state legislators as if seeking to purchase influence over regulatory policy. We find that interests respond defensively to contributions from rivals, take into account the configuration of support available to them in both the legislature and the regulatory commission, and vary their contributions according to variations in relative costs for influence by different legislatures. This strategic behavior supports a theory that commercially motivated interests contribute campaign resources in order to mobilize legislators to influence the decisions of regulatory agencies. We also report evidence that restrictions on campaign finance do not affect all interests equally. The paper therefore provides positive evidence on the nature and effects of campaign contributions in regulated industries where interest group competition may be sharp.

The goal of this paper is to develop and test a model that explains information and communication channel (ICC) choice for knowledge sharing in work teams.

This paper reviews relevant literature in information and knowledge sharing and communication channel choices to develop the four-layered model. From the four-layered model, an online questionnaire was developed to look at the ICCs that participants have available to them, the ICCs they actually use when sharing information in teams, and their motivations for making their ICC choices.

Although participants reported having access to a wide variety of ICCs, they tended to rely on face-to-face interactions, telephone and e-mail for sharing knowledge. In accordance with the four-layer model, participants reported that ICC choice was impacted by the type of knowledge being shared. In addition, ease of use, reliability, convenience, and the ability of the channel to document communications were all factors motivating ICC selection.

The layered model provides a framework for further research to investigate the factors at the outer layers of the four-layered model and the interaction among the layers in affecting ICC choices.

The paper attempts to build a model that organizations can use as a guide to implementing strategies for information and knowledge sharing in teams.

This paper develops and partially tests a model to understand communication choices and information sharing. It provides a framework to examine “traditional” communication choices in the midst of the uproar of the availability of Web 2.0 technologies.

Agricultural education and training (AET) institutions will play a strategic role in helping to prepare Africa’s rapidly growing youth populations for productive careers in agriculture and related agri-businesses. The purpose of this paper is to examine the magnitude of skills and youth employment needs emanating from high-population growth rates. It then explores how agricultural education institutions are responding to these challenges in four different countries at different levels of food system development: South Africa tier 1, Tanzania in tier 2 and Malawi and Uganda in tier 3.

Demographic and school enrollment data provide information on the magnitude of job market entrants at different levels of education while Living Standards Measurement Studies in the respective countries provide a snapshot of current skill requirements in different segments of the agri-food system. In order to evaluate AET responses, the authors have conducted country-level reviews of AET systems as well as in-depth assessments at key tertiary AET institutions in each of the four case study countries.

Growth rates in primary school enrollments are high in sub-Saharan Africa. At the same time, because of budgetary constraints, transition rates decline rapidly – about 40 percent from primary to secondary and 7 percent from secondary to tertiary. As a result, substantial numbers of primary and secondary school graduates seek jobs.

The case study countries are limited to four. Had more financial resources and time been available, researchers could have spread further afield and in so doing increasing the precision of the results.

Estimation of the number of primary and secondary school leavers seeking employment because of failure to proceed to the next level of education. Estimation of the level of education shares in the various components of the agri-food system.

The purpose of this paper is to understand how the unfolding diet transformation in East and Southern Africa is likely to influence the evolution of employment within its agrifood system (AFS) and between that system and the rest of the economy. To briefly consider implications for education and skill acquisition.

The authors link changing diets to employment structure. The authors then use alternative projections of diet change over 15- and 30-year intervals to develop scenarios on changes in employment structure.

As long as incomes in ESA continue to rise at levels near those of the past decade, the transformation of their economies is likely to advance dramatically. Key features will be: sharp decline in the share of the workforce engaged in farming even as absolute numbers rise modestly, sharp increase in the share engaged in non-farm segments of the AFS, and an even sharper increase in the share engaged outside the AFS. Within the AFS, food preparation away from home is likely to grow most rapidly, followed by food manufacturing, and finally by marketing, transport, and other AFS services. Resource booms in Mozambique and (potentially) Tanzania are the main factor that may change this pattern.

Clarifying policy implications requires renewed research given the rapid changes in Africa over the past 15 years.

This is the first paper to explicitly link changing diets to changing employment within the AFS.

High performance computing (HPC) is used to solve complex calculations that personal computing devices are unable to handle. HPC offers the potential for small- and medium-size enterprises (SMEs) to engage in product innovation, service improvement and the optimization of resource allocation (Borstnar and Ilijas, 2019). However, the expensive infrastructure, maintenance costs and resource knowledge gaps that accompany the use of HPC can make it inaccessible to SMEs. By moving HPC to the cloud, SMEs can gain access to the infrastructure without the requirement of owning or maintaining it, but they will need to accept the terms and conditions of the cloud contract. This paper aims to improve how SMEs access HPC through the cloud by providing insights into the terms and conditions of HPC cloud contracts.

This paper adopts a systematic literature review by implementing a four-step approach. A comprehensive search was undertaken and results synthesized to enable this paper’s objectives to be met.

This paper proposes that SMEs could gain competitive advantage(s) by understanding their own needs and improving their contract negotiation abilities, service management skills and risk management abilities before accepting the terms and conditions of the cloud contract. Furthermore, a checklist, service-level agreement, easily ignored elements and risk areas are presented as guidance for SMEs when reviewing their HPC cloud contract(s).

While HPC cloud contracts are a niche research topic, it is one of the key factors influencing the ability of SMEs to access HPC through the cloud. It is, however, by no means a level playfield with SMEs at a distinct disadvantage because of not influencing the writing up of the HPC cloud contract. The added value of the paper is that it contributes to our overall understanding of the terms and conditions of HPC cloud contracts.

After Hurricane Katrina hit the coast of Louisiana on August 29, 2005, Wal-Mart initiated emergency operations that not only protected and reopened its stores, but also helped its employees and others in the community cope with the disaster's personal impact. This response was part of a wider effort by the company under CEO Lee Scott to improve its public image. Wal-Mart's efforts were widely regarded as the most successful of all corporations in the aftermath of the disaster and set the standard for future corporate disaster relief programs.

Move beyond the operational dimensions of disaster response and appreciate how disaster response is connected to the company's strategy and its position in the market place. Understand how disasters are different than other types of reputational crises and are subject to different expectation from the public. Understand how a company can do well by doing good: how it can do the right thing and benefit its business at the same time. Discuss the changing expectations of companies to act in the public interest.

Nowadays, star athletes are global brand personalities. The increased popularity of the professional sport has contributed to elevating exceptional athletes to international star status. This empirical study aims to assess the impact of athlete performance and brand social value on product involvement with the mediation effect of celebrity athlete endorsement.

A quantitative survey was conducted with 399 Chinese participants. PLS-SEM is adopted to examine the associated paths and the mediating effect of celebrity endorsement.

The results demonstrate the significant impact of athlete performance and brand social value on product involvement. Celebrity endorsement partially mediates the effects of athlete performance and brand social value on product involvement.

This study extends understanding of celebrity athlete endorsement and provides insight into the strategic implications for Chinese social media-based marketing initiatives in the context of the recent Olympic Game in Tokyo 2021.

The purpose of the paper is to examine how psychological characteristics predict membership of and transitions between states of higher vs lower financial vulnerability – and vice versa – over time.

This research uses a dynamic latent class model (latent transition analysis) to explore the dynamics of consumers’ financial vulnerability over time using longitudinal data obtained by repeatedly administering a measure of financial vulnerability.

This research finds that consumers in a state of lower vulnerability are “fragile” in having a relatively high likelihood of moving to a state of higher vulnerability, whereas those in a state of higher vulnerability are “entrenched” in having a relatively low likelihood of moving to a state of lower vulnerability. This pattern of results is called the “financial vulnerability trap.” While financial self-efficacy explains state membership, the consideration of future consequences drives state transitions.

Future research could follow consumers over a longer period and consider the role of alternative psychological characteristics besides those examined.

This research provides practitioners with actionable insights regarding the drivers of changes in consumers’ financial vulnerability across time, showing the value of financial self-efficacy and the consideration of future consequences when developing strategies to prevent consumers from sliding from a state of lower to higher financial vulnerability over time.

There is scant research on financial vulnerability. Further, prior research has not examined whether and how consumers’ psychological characteristics help explain their membership of and transitions between states of different levels of financial vulnerability over time.
