Epidemiological patterns of suicide terrorism in the civilian Pakistani population

In this study, we assessed the epidemiological patterns of suicide terrorism in the civilian population of Pakistan. Information about suicide terrorism-related events, deaths and injuries was extracted from the South-Asian Terrorism Portal (SATP) for the period from 2002 to October 2009. Of 198 events, civilians were involved in 194 events. Civilians accounted for 74.1% (N?=?2017) of those who died and 93.8% (N?=?6129) of those who were injured. In nine districts, mortality rates were more than one death per 100,000 inhabitants per year. The yearly trend showed a shift of attack targets from foreigners and sectarian targets in 2002-2005 to security forces or general public in 2006-2009. Attacks on public installations (mosques) or political gatherings resulted in a significantly greater (P?≤?0.02) number of deaths (22 vs. 8) and injuries (59 vs. 24) per event compared with security installations. These results show that prevention might focus on political negotiation with armed groups and that appropriate measures should be taken to protect mosques and political gatherings.     

Diversification evidence from international equity markets using extreme values and stochastic copulas

Tail dependence plays an important role in financial risk management and determination of whether two markets crash or boom together. However, the linear correlation is unable to capture the dependence structure among financial data. Moreover, given the reality of fat-tail or skewed distribution of financial data, normality assumption for risk measure may be misleading in portfolio development. This paper proposes the use of conditional extreme value theory and time-varying copula to capture the tail dependence between the Australian financial market and other selected international stock markets. Conditional extreme value theory enables the model adequacy and the tail behavior of individual financial variable, while the time-varying copula can fully disclose the changes of dependence structure over time. The combination of both proved to be useful in determining the tail dependence. The empirical results show an outperformance of the model in the analysis of tail dependence, which has an important implication in cross-market diversification and asset pricing allocation.     

Conditioning manager alphas on economic information: another look at the persistence of performance

This article presents evidence on persistence in the relativeinvestment performance of large, institutional equity managers.Similar to existing evidence for mutual funds, we find persistentperformance concentrated in the managers with poor prior-periodperformance measures. A conditional approach, using time-varyingmeasures of risk and abnormal performance, is better able todetect this persistence and to predict the future performanceof the funds than are traditional methods.     

Is quality management a prime requisite for globalization? Some facts from the sports industry

Countries have progressed during the decades through internationalization of their products. Pakistan is also trying hard to internationalize its products and has succeeded as far as the textile and sport ware industries are concerned. Pakistani Sports industry, though always relying on high quality products, lacked a formal quality management program till 1990’s. It was during this decade that most sports industries adopted a formal quality management program in the shape of ISO-9000. This paper encompasses different aspects of quality management and establishes its role in internationalization. Research findings presented in this paper are carried out in two phases. In phase-I, the detailed analysis of 6 sports industries is done, whereas in phase-II, a survey of one hundred industries was conducted and the role of quality management was established based on obtained results. It was found that 85% companies adopted ISO-9000 as a formal quality management program. The quality impact on internationalization was probed and it was found that the following quality management programs increased the sale, exports, profitability and the well being of the owner and the workers.     

US domestic airline alliances: does the national welfare impact turn on strategic international gains?

The six largest U.S. airlines announced in the beginning of 1998 the formation of three domestic alliances, but the size and scope of these alliances spurred significant public interest concerns. GAO analysis suggests a rough equivalence between the domestic costs and benefits of alliances, yet the international competitive effects have not been considered. I argue that the national welfare merits of domestic airline alliances turn on positive international competitive effects. Empirical tests - run on comprehensive panel data covering the international airline markets among 21 nations over the 1983–1992 period - support domestic market concentration resulting in strategic international gains; hence, domestic airline alliances likely improve national welfare.     

Countering Service Information Challenges in the Internet of Services

Business Webs apply the idea of value networks to the WWW. The underlying delivery platform is commonly referred to as the Internet of Services and will certainly have to deal with a great variety and amount of information about services along several service information dimensions. As soon as brokerage, discovery, or community feedback parts are decentralized, there emerge a number of service information challenges (modeling the information in a holistic way, documentation, interlinkage, tool interoperability, distributed querying, inconsistent information, and cooperation of different stakeholders). In this paper, we propose to counter such service information challenges by two artifacts. First, we contribute a Service Ontology based on a sound and rigid foundational ontology. The Service Ontology provides a holistic and consistent way of capturing service information. We apply the recommendations of the W3C Semantic Web Activity whose recent standardization has already opened new possibilities for tool interoperability, interlinkage of information, and distributed querying on the web. However, building and prescribing an ontology in standardized languages is not enough to address all service information challenges. Therefore, as a second contribution, we provide a method around the ontology including a governance framework, guidelines for applying the W3C Semantic Web recommendations, a lifecycle-spanning tool chain, and different levels of applicability. We label our method Semantic Business Web approach, since we build on W3C Semantic Web standards, use and extend them in the Business Web setting. Both artifacts are constructed in an interdisciplinary way by experts participating in the German lighthouse project THESEUS/TEXO. The project’s scenario also serves as a proof of concept evaluation of the artifacts.     

SOME EVIDENCE ON MEAN REVERSION IN EX ANTE REAL INTEREST RATES

Ex ante real interest rates and their differentials are tested for mean reversion using quarterly data on three-month treasury bill rates and consumer prices for 12 major industrial countries over the period 1972:l-1993:3. The results are strongly supportive of mean reversion, particularly when less conventional tests are employed. The conclusion that can be derived from the empirical evidence is that goods, capital and foreign exchange markets have become highly integrated in the countries under consideration.     

The key performance indicators (KPIs) and their impact on overall organizational performance

The concept of performance management is used by most of the organizations to ensure that either they are going on the right path or not. For managing the performance the organizations are required to know about the performance indicators. This paper explores the key performance indicators (KPIs) and impact of these KPIs on the overall organizational performance in manufacturing sector in Pakistan. The data for present study collected from the top level management of the 84 best manufacturing organizations in Pakistan by using a structured questionnaire and the impact of KPIs on the overall performance of the manufacturing organizations were evaluated. The results show that the manufacturing organizations put more focus on the customer satisfaction and Delivery reliability in terms of performance measurement. And measuring the performance in terms of cost, financial, quality, time, flexibility, delivery reliability, safety, customer satisfaction, employees’ satisfaction and social performance indicators have positive significant impact on the overall organization’s performance. This paper puts together all important performance indicators used by organizations in a single list and check their impact on the overall performance indicator index of the Organizations. As Pakistan is among the developing countries, this study will serve as a valuable guideline for several manufacturing organizations operating in other developing countries of the world.
