Transformational leadership, transactional leadership, organizational cultural behaviors and effectiveness of knowledge management practices in higher educational institutions

The purpose of this study is to examine the relationship between critical success factors such as transactional leadership, transformational leadership, and cultural behavior and knowledge management (KM) effectiveness in the context of higher education. A questionnaire survey will be employed to collect data in 3 US-based universities and colleges. Statistical analysis methods such as multiple regression analysis, the multivariate analysis will be performed to find a correlation between the different variables

Knowledge Sharing and the Psychological Contract: Managing Knowledge Workers across Different Stages of Employment

Purpose – An employee’s willingness to share knowledge may be contingent on whether the organization equitably fulfills its reward obligations. This paper seeks to examine how managers and organizations can be vehicles for managing psychological contract perceptions favoring knowledge sharing among current employees, newcomers, and applicants. Design/methodology/approach – The authors propose an integrative model to discuss psychological contract issues within each stage of employment and HRM initiatives that can encourage knowledge-sharing behaviors. Findings – The implicit psychological contracts that often influence knowledge worker attitudes for sharing knowledge are easy to overlook and challenging to manage. Managers must properly assess the nature of psychological contracts maintained by such workers so that knowledge-sharing messages address employees’ key motivators. Different psychological contracts exist at various stages of employment. Several prescriptions for effectively managing each type of psychological contract and reducing perceptions of PC breach were offered. Research limitations/implications – Empirical studies should seek to investigate whether different psychological contracts actually exist within a field setting. In addition, how workers move between transitional, transactional, balanced and relational psychological contracts should be empirically examined. Originality/value – The authors sought to better understand the different psychological contract perceptions of knowledge workers at various stages of employment, which has not been done to date. Such workers are keenly aware of the impact of their knowledge and effective management for sharing rather than hoarding becomes a critical success factor for knowledge-intensive organizations

Tuning the Level of Concurrency in Software Transactional Memory: An Overview of Recent Analytical, Machine Learning and Mixed Approaches

Synchronization transparency offered by Software Transactional Memory (STM) must not come at the expense of run-time efficiency, thus demanding from the STM-designer the inclusion of mechanisms properly oriented to performance and other quality indexes. Particularly, one core issue to cope with in STM is related to exploiting parallelism while also avoiding thrashing phenomena due to excessive transaction rollbacks, caused by excessively high levels of contention on logical resources, namely concurrently accessed data portions. A means to address run-time efficiency consists in dynamically determining the best-suited level of concurrency (number of threads) to be employed for running the application (or specific application phases) on top of the STM layer. For too low levels of concurrency, parallelism can be hampered. Conversely, over-dimensioning the concurrency level may give rise to the aforementioned thrashing phenomena caused by excessive data contention—an aspect which has reflections also on the side of reduced energy-efficiency. In this chapter we overview a set of recent techniques aimed at building “application-specific” performance models that can be exploited to dynamically tune the level of concurrency to the best-suited value. Although they share some base concepts while modeling the system performance vs the degree of concurrency, these techniques rely on disparate methods, such as machine learning or analytic methods (or combinations of the two), and achieve different tradeoffs in terms of the relation between the precision of the performance model and the latency for model instantiation. Implications of the different tradeoffs in real-life scenarios are also discussed

Law Firm Selection and the Value of Transactional Lawyering

Following the contraction in demand for law firms’ services during the Great Recession, “Big Law” was widely diagnosed as suffering from several maladies that would spell its ultimate demise, including excessive fees, excessive size, increased competition from in-house counsel, the commoditization of legal work, and the decline in demand for “relationship firms.” While each of these market pressures is only too real for certain segments of the law-firm population, their threat to the most elite U.S. law firms has been largely misunderstood. Even as many firms reduce their fees and contract in size, we should expect certain firms to continue to charge more and grow bigger. The current prescriptions for fixing Big Law fail to recognize that the top-tier firms within the group serve a unique market function. Focusing on a particular type of legal work – major corporate transactions – this Article proposes a novel theory of the value created by elite law firms: their private information about “market” deal terms, acquired through repeated exposure to the same types of transactions, provides clients with a significant bargaining advantage in deal negotiations. By aggregating expertise in the ever-changing and ever-increasing set of deal terms for certain transactions, law firms help their clients price such terms more accurately and thereby maximize their surplus from the deal. This pricing function – traditionally thought to be limited to investment banks – is one that cannot be replicated or subsumed by in-house counsel, other service providers, or commoditized contracts

Relationship Between Internal Branding Practices, Brand Commitment and Employees' Brand Citizenship Behavior

Despite the growing popularity of the concept of internal branding in aligning employees’ brand behavior, little is known on how internal branding practices affect employees’ behavior toward the organization’s brand. The dearth of research in this field also limits the understanding of what is the appropriate employees’ behavior that could enhance their organization’s brand performance. Therefore, this study attempts to link the relationship of internal brand practices (namely brand knowledge, brand leadership and brand rewards) on employees’ brand citizenship behavior . Built based on Stimulus-Organism-Response Model, this study also attempts to test the mediation role of employees’ brand commitment on the initial relationship. 288 employees from twelve hotels in northern region of Malaysia in Perlis, Kedah and Penang consisted of three to five star rating participated in this study. Two parts of regression analyses were conducted. The first part dealt with general model specifically to answer the main hypotheses while the second part specifically conducted to answer subhypotheses of relationship between dimensions of each variable. The findings revealed that brand knowledge, brand leadership and brand rewards have a significant positive relationship with brand citizenship behavior as well as brand commitment. However, brand commitment only partially mediates the relationship between brand knowledge and brand leadership on brand citizenship behavior and fully mediate the relationship between brand rewards on brand citizenship behavior. The test of subhypotheses revealed that brand meaning, responsibility to deliver brand promise, transformational brand leadership and brand rewards have a significant positive relationship with helping behavior and self-brand-development. Sportsmanship is influenced by transactional and transformational brand leadership and brand rewards while brand endorsement is influenced by transactional brand leadership and brand rewards. Brand compliance partially mediates the relationship between brand rewards on sportsmanship while brand engagement partially mediates the relationship of (1) transformational brand leadership on helping behavior and (2) brand meaning and transformational brand leadership on self-brand-development

Analytical/ML Mixed Approach for Concurrency Regulation in Software Transactional Memory

In this article we exploit a combination of analytical and Machine Learning (ML) techniques in order to build a performance model allowing to dynamically tune the level of concurrency of applications based on Software Transactional Memory (STM). Our mixed approach has the advantage of reducing the training time of pure machine learning methods, and avoiding approximation errors typically affecting pure analytical approaches. Hence it allows very fast construction of highly reliable performance models, which can be promptly and effectively exploited for optimizing actual application runs. We also present a real implementation of a concurrency regulation architecture, based on the mixed modeling approach, which has been integrated with the open source Tiny STM package, together with experimental data related to runs of applications taken from the STAMP benchmark suite demonstrating the effectiveness of our proposal. © 2014 IEEE

"I can decide to use the property I have to make money": HIV vulnerability of bar workers and bar patrons in Kumasi, Ghana

This study was implemented by Boston University in collaboration with the Kwame Nkrumah University of Science and Technology with support from the President’s Emergency Plan for AIDS Relief (PEPFAR) through the U.S. Agency for International Development under Project SEARCH Task Order No. GHH‐I‐00‐07‐00023‐00, beginning August 27, 2010. The content and views expressed here are the authors’ and do not necessarily reflect the opinion or policy of USAID or the U.S. Government.This report provides the findings from a qualitative study exploring the social, economic and behavioral vulnerability to HIV of women working in bars and restaurants in Kumasi, Ghana’s second largest city. This research was conducted by a collaborative team comprised of researchers from Boston University’s Center for Global and Health and Development (CGHD) and the Kwame Nkrumah University of Science and Technology (KNUST) School of Medical Sciences. It is one of nine studies under the Operations Research on Key Populations project funded by the United States Agency for International Development (USAID). The study was designed and carried out in collaboration with the Ghana AIDS Commission (GAC). Reducing vulnerability to HIV infection among key populations in Ghana is a major goal for the National AIDS Control Program (NACP) and the GAC. While a number of studies have explored HIV risk behaviours among self-identified female sex workers and their partners in Ghana, little is known about the vulnerability of women working in small bars and restaurants who may be involved in transactional sex. Further, we have little information about how best to reach this population with services that will enable them and their clientele to protect themselves from HIV and reduce other vulnerabilities related to their health and well-being. To address this gap, this study aimed to explore behavioural, social, and economic factors that contribute to HIV vulnerability; types and extent of transactional sex; the relationship between alcohol/drug use, unsafe sex and transactional sex; and the health and social service needs of this population. The study findings are meant to inform the development and implementation of HIV prevention programs for bar workers and bar patrons.Support from the President’s Emergency Plan for AIDS Relief (PEPFAR) through the U.S. Agency for International Development under Project SEARCH Task Order No. GHH‐I‐00‐07‐00023‐00, beginning August 27, 201

Exploring the Behavior of Highly Effective CIOs Using Video Analysis

Although recently several studies have addressed the required skills of effective CIOs, little is known of the actual behavior successful CIOs. In this study, we explore the behavior of highly effective CIOs by video-recording CIOs at work. The two CIOs videotaped were nominated as CIO of the year. We analyze the data in an innovative and systematic way by developing and using a behavioral leadership coding scheme. The analysis indicates that highly effective CIOs are good listeners. They also often verify previously made agreements; structure the conversation; and provide subordinates with factual information. We also compare the behavior of the highly effective CIOs to a sample of 25 highly effective middle managers. Whereas the CIOs spend little time defending themselves against their subordinates and are mostly involved in steering, middle-managers spend much more time defending themselves and show more support for their subordinates. We conclude that our new video observation-and-coding method is viable to analyze and better understand the behavior of CIOs

Research report: "Using what you have to get what you want": Vulnerability to HIV and prevention needs of female post‐secondary students engaged in transactional sex in Kumasi, Ghana

This study was implemented by Boston University in collaboration with the Kwame Nkrumah University of Science and Technology with support from the President’s Emergency Plan for AIDS Relief (PEPFAR) through the U.S. Agency for International Development under Project SEARCH Task Order No. GHH‐I‐00‐07‐00023‐00, beginning August 27, 2010. The content and views expressed here are the authors’ and do not necessarily reflect the opinion or policy of USAID or the U.S. Government.This report presents findings from a qualitative study examining vulnerability to HIV of female post‐secondary students engaged in transactional sex in Kumasi, Ghana and their prevention needs. The study was conducted by Boston University’s Center for Global and Health and Development (CGHD) and the Kwame Nkrumah University of Science and Technology (KNUST) as part of Project SEARCH funded by the United States Agency for International Development Ghana. Participants were recruited from five post‐secondary institutions in the greater Kumasi area. Our objective is to provide academic institutions, the Ghana AIDS Commission (GAC), the National AIDS Control Program, donors, and other stakeholders with rich data to inform research and programmatic efforts in Kumasi specifically, as well as academic institutions in general. We set out to document what forms of transactional sex female students are engaging in, who their partners are, and what motivates them to participate. We asked students about the individual and structural vulnerabilities for HIV reported by female post‐secondary students involved in transactional sex and what their prevention needs are. We also interviewed a small sample of faculty, residence hall matrons, and hotel staff to get their perspective on the behavior of female students practicing transactional sex that might put them at risk for HIV. The findings of this study can be used as well to inform the design of future studies of young women engaging in transactional sex in Ghana. With such limited understanding of HIV transmission among young female post‐secondary students engaged in transactional sex, research is needed to determine how this group contributes to the overall HIV epidemic. The Ghana AIDS Commission has recognized the need for further research among communities engaged in less well‐defined risky sex practices in the National Strategic Plan for Most‐at – Risk Populations (MARP) 2011‐2015.4 This study attempts to fill in gaps in the research regarding transactional sex, taking into account the complexities and nuances of the practice, in addition to examining the needs of female students for targeted HIV prevention programs.Support from the President’s Emergency Plan for AIDS Relief (PEPFAR) through the U.S. Agency for International Development under Project SEARCH Task Order No. GHH‐I‐00‐07‐00023‐00, beginning August 27, 201
