Deployment Issues And Security Concerns With Wireless Local Area Networks: The Deployment Experience At A University

This paper presents and discusses various issues pertaining to the deployment of Wireless Local Area Networks (WLANs).  The popularity of WLANs has steadily increased in the last two years and has led to their deployment in a variety of organizations.  Yet, making a business case for WLANs is an important step in their deployment.  In addition to highlighting the need for a business case for WLAN deployment, the paper outlines the reasons for, benefits of, and security problems associated with, their deployment.  The latter part of this paper presents a case study about the deployment of a WLAN at the University of Akron.  Therein, it discusses the context for the deployment, the process that was used to justify the deployment, and the efforts made to protect users’ information from security deficiencies of wireless networks

Off-Shoring And Outsourcing

Because of a dramatic decrease in transportation and telecommunication costs, the digital revolution, and the forces of globalization, off-shoring has accelerated in the past few years.  While there is little doubt that off-shoring has brought hardship to thousands of workers and communities, there is also little doubt that it has benefited many worker and communities.  Today, off-shoring continues to generate considerable debate on the long-run impact. Also, there is considerable misunderstanding about this phenomenon.  In this paper, the authors make a distinction among the terms outsourcing, offshore outsourcing, and off-shoring.  Off-shoring has been facilitated by a deconstruction of the value chain, allowing firms to evaluate all activities as potential candidates for being performed outside the firm.  Reasons for the acceleration of off-shoring are outlined.  An explanation of why off-shoring is not a villain for the developed economies is also provided

Role Of Institutions In Growth Of Countries

The purpose of this paper was to look at the role of institutions in growth of countries. We compared income and quality of institutions’ data among 87 developing countries to see if institutions that promote economic freedom and investment lead to higher economic growth. In addition, we wanted to look at the role of institutions in economic growth at the local level in a country. For this analysis, we compared income and quality of institutions’ data for different states in India. In both cases, we found that growth is significantly affected by the quality of institutions

Directive versus empowering leadership: A field experiment comparing impacts on task proficiency and proactivity

Using a field experiment in the United Arab Emirates, we compared the impacts of directive and empowering leadership on customer-rated core task proficiency and proactive behaviors. Results of tests for main effects demonstrated that both directive and empowering leadership increased work unit core task proficiency, but only empowering leadership increased proactive behaviors. Examination of boundary conditions revealed that directive leadership enhanced proactive behaviors for work units that were highly satisfied with their leaders, whereas empowering leadership had stronger effects on both core task proficiency and proactive behaviors for work units that were less satisfied with their leaders. We discuss implications for both theory and practice. © Academy of Management Journal

BCL2 Translocation Defines a Unique Tumor Subset within the Germinal Center B-Cell-Like Diffuse Large B-Cell Lymphoma

Gene expression profiling of diffuse large B-cell lymphoma (DLBCL) has revealed prognostically important subgroups: germinal center B-cell-like (GCB) DLBCL, activated B cell-like (ABC) DLBCL, and primary mediastinal large B-cell lymphoma. The t(14;18)(q32;q21) has been reported previously to define a unique subset within the GCB-DLBCL. We evaluated for the translocation in 141 cases of DLBCL that were successfully gene expression profiled. Using a dual-probe fluorescence in situ hybridization assay, we detected the t(14;18) in 17% of DLBCLs and in 34% of the GCB subgroup which contained the vast majority of positive cases. In addition, 12 t(14;18)-positive cases detected by polymerase chain reaction assays on additional samples were added to the fluorescence in situ hybridization-positive cases for subsequent analysis. Immunohistochemical data indicated that BCL2, BCL6, and CD10 protein were preferentially expressed in the t(14;18)-positive cases as compared to t(14;18)-negative cases. Within the GCB subgroup, the expression of BCL2 and CD10, but not BCL6, differed significantly between cases with or without the t(14;18): 88% versus 24% for BCL2 and 72% versus 32% for CD10, respectively. In the GCB-DLBCL subgroup, a heterogeneous group of genes is overexpressed in the t(14;18)-positive subset, among which BCL2 is a significant discriminator. Interestingly, the t(14;18)-negative subset is dominated by overexpression of cell cycle-associated genes, indicating that these tumors are significantly more proliferative, suggesting distinctive pathogenetic mechanisms. However, despite this higher proliferative activity, there was no significant difference in overall or failure-free survival between the t(14;18)-positive and -negative subsets within the GCB subgroup

Are the GCC FDI Location Determinants Favorable?

Diversifying income sources is one of the main challenges the GCC countries currently face. FDI can be beneficial in this regard. FDI can help the GCC countries gain access to technology, adopt innovation in the production process, obtain new expertise and managerial know-how, and expand production, marketing, transport, and communication networks. Despite the FDI potential benefits to and the FDI potential of the GCC countries, FDI flows declined in absolute and relative terms. This paper examines the question of whether the location determinants are favorable to FDI in the GCC region. Using panel data for the period 1980-2002, panel data model estimates suggest that market size, as measured by real GDP per capita, and trade openness have positive influence on FDI flows, while institutional quality has a statistically significant positive influence when the period 1980-1982 was dropped from the sample period. Surprisingly human capital deters FDI flows

Competition and Market Strategies in the Swiss Fixed Telephony Market. An estimation of Swisscom’s dynamic residual demand curve.

Fixed telephony has long been a fundamentally important market for European telecommunications operators. The liberalisation and the introduction of regulation in the end of the 1990s, however, allowed new entrants to compete with incumbents at the retail level. A rapid price decline and a decline in revenues followed. Increased retail competition consequently led a number of national regulators to deregulate this market. In 2013, however, many European countries (including Switzerland) continued to have partially binding retail price regulation. More than a decade after liberalisation and the introduction of wholesale and retail price regulation, sufficient data is available to empirically measure the success of regulation and assess its continued necessity. This paper develops a market model based on a generalised version of the traditional “dominant firm – competitive fringe” model allowing the incumbent also more competitive conduct than that of a dominant firm. A system of simultaneous equations is developed and direct estimation of the incumbent‟s residual demand function is performed by instrumenting the market price by incumbent-specific cost shifting variables as well as other variables. Unlike earlier papers that assess market power in this market, this paper also adjusts the market model to ensure a sufficient level of cointegration and avoid spurious regression results. This necessitates introducing intertemporal effects. While the incumbent's conduct cannot be directly estimated using this framework, the concrete estimates show that residual demand is inelastic (long run price elasticity of residual demand of -0.12). Such a level of elasticity is, however, only compatible with a profit maximising incumbent in the case of largely competitive conduct (conduct parameter below 0.12 and therefore close to zero). It is therefore found that the Swiss incumbent acted rather competitively in the fixed telephony retail market in the period under review (2004-2012) and that (partial) retail price caps in place can no longer be justified on the basis of a lack of competition
