Abstract
Data‐centric storage is an efficient scheme to store and retrieve event data in sensor networks, but with the multi‐hop routing nature of sensor networks, the communication cost of the home nodes and their neighboring nodes tends to be much higher than the other nodes. These hot‐spots can adversely impact system lifetime by draining off their limited energy rapidly. In this paper, we present Zone‐Repartitioning, a load‐balancing mechanism that reduces the energy consumption of the hot‐spots by distributing their communication load while event frequency is high. The trade‐off between event storage cost and query cost makes Zone Repartitioning a competitive approach in different kinds of applications. We compare the performance of Zone Repartitioning against GHT and show that Zone Repartitioning provides better adaptability in various sensor network scenarios.

Abstract
Lewis Byrd, a partner in the private equity firm Opportunity Capital Partners, is managing a number of interconnected issues. First, in his role as investment professional responsible for the firm's investment in a doghouse manufacturing company called Dogloo, he has to manage a relationship with an entrepreneur who has behaved in a way that has made coinvestors nervous about his skills as a CEO. The CEO, Aurelio Barretto, is a Cuban immigrant who has established a close confiding relationship with Byrd, who is an African American. Barretto has increasingly relied on Byrd to run interference for him with investors, while also providing the strategic advice that typically supports an investor-entrepreneur relationship. Another issue is that there is a potentially costly lawsuit looming involving copyright infringement by a larger, well-funded competitor in the pet products market. Byrd has to manage potentially volatile relationships while determining what's best for his firm from an investment standpoint and how best to advise Barretto to proceed. The case provides insights into the challenges in private equity investing that occur after the striking of the financial deal. The case also provides information for students about the technical and legal structure of private equity financing.

Abstract
Investigates the differences in protocols between arbitral tribunals and courts, with particular emphasis on US, Greek and English law. Gives examples of each country and its way of using the law in specific circumstances, and shows the variations therein. Sums up that arbitration is much the better way to gok as it avoids delays and expenses, plus the vexation/frustration of normal litigation. Concludes that the US and Greek constitutions and common law tradition in England appear to allow involved parties to choose their own judge, who can thus be an arbitrator. Discusses e‐commerce and speculates on this for the future.

Abstract
The purpose of the current study was to assess the impact of information technology on strategic flexibility for small- and medium-sized enterprises (SMEs). Results of the study show that under conditions of low environmental dynamism, IT capabilities are associated with greater reactive strategic flexibility. Specifically, IT capabilities enabling the management of internal activities was significant. Under conditions of high environmental dynamism, IT capabilities are associated with greater proactive strategic flexibility. Specifically, IT capabilities enabling the management of competitor information was significant. Managerial as well as future research implications are discussed.

Abstract
We argue that voice – the sound that people produce when they speak – is an important resource for entrepreneurs, especially when they are pitching to potential investors. We integrate evidence from entrepreneurship, social psychology and linguistics to show that the voice can be regarded both as a tool for entrepreneurs to utilize and as a vital source of information allowing listeners to make judgements about the speaker and their message. To better understand how the voice may be used and interpreted in investment pitches, we develop a model of the relationship between the entrepreneurial voice and investor judgments. Voice depends on entrepreneurs’ characteristics including gender and communication goals but can be utilized to express emotions (purposefully or not) and signal qualities such as competence and trustworthiness. How potential investors interpret these displays depends on cultural expectations and stereotypes. Our review illustrates that female entrepreneurs may find it more difficult to persuade investors due to their naturally higher voice pitch and bias against speech patterns prevalent among young women. We highlight directions for future research exploring the voice as a unique cultural resource for entrepreneurs.

Abstract
This chapter reviews ethical challenges confronting nonprofit administration in relation to organizational managerial practices and leadership behaviors. Through a theoretical model of nonprofit-specific toxic leadership, it reviews the dynamics of destructive leaders, susceptible followers, and conducive environments in cases of unethical and corrupt nonprofit organizational behaviors. It provides a case for prioritizing oversight responsibilities of the board of directors, board supervision, promoting ethical culture in organizational leadership, and implementing policies for addressing destructive and corrupt nonprofit leaders. It reflects on how nonprofit toxic leadership primarily erodes public trust in the nonprofit sector and concludes with practical recommendations for recentering positive behaviors congruent with the nonprofit's social and public good mission.
