Building relationship innovation in global collaborative partnerships: big data analytics and traditional organizational powers

This study examines how relationship innovation can be developed in global collaborative partnerships (alliances, joint ventures, mergers, and acquisitions). The recently emerging theory of big data analytics linked with traditional organizational powers has attracted a growing interest, but surprisingly little research has been devoted to this important and complex topic. Therefore, after developing the theoretical foundations, our study empirically quantifies the links between the theoretical constructs based on the data collected from chief executive officers, managing directors, and heads of departments who work in contemporary global data‐and‐information driven collaborative partnerships. The results from structural equation modeling indicate that the relationship innovation depends on the power of big data analytics and non‐mediated powers (NMP, expert and referent). The power of big data analytics also mediates the correlation between NMP and relationship innovation. However, mediated powers (coercive and manipulative) negatively affect the power of big data analytics and relationship innovation. The interaction effects further depict that analytically powered partnerships have better relationship innovation compared with those which focus less on the analytical power. Consequently, the contributions of this study provide a deeper understanding of mechanisms of how modern collaborative partnerships can use big data analytics and traditional organizational powers to co‐create relationship innovation.     

Effect of public programs on family size,child education and health

"A bulk of public resources in developing countries is devoted to the subvention of population control and health investments. The effects of these programs have been evaluated in this study with household and community data from Bangladesh. The results suggest that subsidy on family planning and secondary school would be most effective in the achievement of harmonious goals of reducing fertility and mortality and fostering investments in child education."     

Minimising emergency response time of ambulances through pre-positioning in Dhaka city,Bangladesh

This study conducted a large-scale survey in Dhaka, Bangladesh; the survey involved 95 major hospitals, more than 3000 emergency room patients, and 2 of the largest ambulance operators. Currently, most ambulances are parked within the vicinity of hospitals and are either dispatched or fetched by the acquaintances of the patient on demand, resulting in lengthy round trips. Reducing the response time of ambulances would certainly improve the emergency service, and pre-positioning of the ambulances could be a solution to reducing the response time. This study used two approaches to address the problem. First, the location-allocation problem was solved to find the optimal number of ambulance locations by maximising the demand coverage. Second, separate location-allocation for the peak and off-peaks, using K-means clustering, was applied to systematically optimise the ambulance positioning in small clusters near demand points. These approaches could substantially improve the existing emergency response time. Distributing ambulances near demand points yielded greater improvements in response time than when the ambulances are stationed near hospitals.     

Market Risk Disclosures and Investment Efficiency: International Evidence from the Gulf Cooperation Council Financial Firms

This study examines the association between market risk disclosures (MRDs) and the investment efficiency of financial firms from six emerging markets in the Gulf Cooperation Council (GCC) region. Based on a sample of 553 firm‐year observations over the 2007–2011 period, we find that MRDs are significantly and negatively associated with both under‐investment and over‐investment and that this association is more pronounced for larger firms. We also find that the association between MRDs and under‐investment is moderated during periods of economic distress such as the Global Financial Crisis of 2008 and that the association between MRDs and over‐investment is magnified during periods of reduced financial distress. Our results are consistent with the idea that MRDs reduce information asymmetry, which ultimately improves investment efficiency. We contribute to the literature in an emerging market context by providing empirical evidence on the association between MRDs and investment efficiency across six emerging GCC capital markets. This study also fills a gap in the literature by providing evidence on the factors affecting the investment efficiency of financial firms.     

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.     

Organizational differences in managerial compensation and benefits in Chinese firms

More than two decades of economic reforms have brought profound changes in human resource management practices in both the state and non-state sectors in China. This study focuses on the impact of organizational factors on compensation and benefits for Chinese managers in state-owned enterprises (SOEs), publicly listed firms (PLFs), and foreign-invested enterprises (FIEs). The empirical investigation of 465 firms located in three major Chinese cities, Shanghai, Nanjing and Guangzhou, provides evidence that organizational factors, such as ownership, firm size, firm age, location and industrial sector, have significant impacts on the variances in Chinese managers' compensation levels, compensation structures and benefits. The trends in the development of compensation and benefits for Chinese managers are also discussed as the Chinese economy moves closer to a more globalized, highly dynamic economy after China's accession to the World Trade Organization in 2001.     

Reprint of: Stock salience and the asymmetric market effect of consumer sentiment news

We document asymmetric announcement effects of consumer sentiment news on United States stock and stock futures markets. While a negative market effect occurs upon the release of bad sentiment news, there is no market reaction for the counterpart good news. This supports the “negativity effect” hypothesis. Notably, this effect seems most likely to occur in salient stocks, which is consistent with the availability heuristic.     

TD-LTE抢占无线全新商机

如今,为了努力满足用户对移动数据日益增长的需求,大部分运营商的网络和频段都在满负荷运行。据相关数据显示,2010年用户每月使用的数据流量已经超过了5GB。由于数据增长的关键驱动因素——smartphone的普及率在全球仍低于20%,运营商预计用户每月使用的数据流量仍将继续增长。因此,如何充分利用自身的频谱资源、开发包括TD-LTE在内的不同技术选择的潜力,就成为运营商极为关注的重要课题。     

Modelling of narrow money demand in Australia: an ARDL cointegration approach, 1970–2009

Using annual data for the period 1970?C2009, this paper deploys the ARDL cointegration approach to determine whether there exists an economically meaningful, stable narrow money demand relationship in Australia. The statistical results suggest the presence of a long-run equilibrium relationship between real narrow money balances, real income, a representative domestic interest rate (e.g., the yield on Australian government short-term bonds) and the nominal effective exchange rate of the Australian dollar. The statistical tests suggest no significant instability in the narrow money demand relationship despite financial deregulation and innovation in Australia since the early 1980s. In contrast, the paper reports statistical results which suggest no meaningful, stable broad money demand relationship in Australia over the sample period.
