Type I error and test power of different tests for testing interaction effects in factorial experiments

A simulation study was conducted to investigate the effect of non normality and unequal variances on Type I error rates and test power of the classical factorial anova F‐test and different alternatives, namely rank transformation procedure (FR), winsorized mean (FW), modified mean (FM) and permutation test (FP) for testing interaction effects. Simulation results showed that as long as no significant deviation from normality and homogeneity of the variances exists, generally all of the tests displayed similar results. However, if there is significant deviation from the assumptions, the other tests are observed to be affected at considerably high levels except FR and FP tests. As a result, when the assumptions of factorial anova F‐test are not met or, in the case those assumptions are not tested whether met, it can be concluded that using FR and FP tests is more suitable than the classical factorial anova F‐test.     

Interaction of organizational commitment and job satisfaction of nurses and medical secretaries in Turkey

The main aims of this study is to explain the relationship between job satisfaction and organizational commitment and to investigate the effects of gender, education level, age, monthly income, ownership type of the employed hospital, length of employment in the hospital, job and marital status on organizational commitment and job satisfaction. The research was carried out in three hospitals in Turkey. The research population includes 872 people: 677 nurses and 195 medical secretaries. All the questions on the research instruments were answered by 55.4% of the population. A significant and positive relationship was found between job satisfaction and organizational commitment.     

Manipulation through political endorsements

We study elections with three candidates under plurality voting. A candidate is a Condorcet loser if the majority of the voters place that candidate at the bottom of their preference rankings. We first show that a Condorcet loser might win the election in a three-way race. Next we introduce to the model an endorser who has private information about the true probability distribution of the preferences of the voters. Observable endorsements facilitate coordination among voters who may otherwise split their votes and lead to the victory of the Condorcet loser. When the endorser has an ideological bias towards one of the candidates, the coordination impact of endorsements remains unaltered, moreover the endorser successfully manipulates the outcome of the election in favor of his bias, even if his ideological bias is known by the voters. The results are true for any endorsement cost and any magnitude of bias as long as the electorate is large enough.     

HRM and performance—The role of talent management as a transmission mechanism in an emerging market context

This paper investigates the link between HRM practices, talent management (TM), and firm performance and examines the role of HRM/business strategy alignment in an emerging market context. Through survey evidence gathered from 198 respondent firms, this study shows that TM, when focused on a series of practices aimed at developing workforce networks and social capital, is a key transmission mechanism mediating the relationship between HRM and firm performance. HRM strategy and business strategy alignment increases these performance impacts but is not an essential component in the HRM‐TM‐performance link.     

Population heterogeneity and growth

I investigate the robustness of the link between growth and heterogeneity in a population along ethnic, linguistic, religious, and socio-economic class lines using cross-country data covering the period 1960–92 and 72 countries. In addition to 21 distinct explanatory variables extensively used in the empirical growth literature, I consider several fragmentation and polarization indices capturing the heterogeneity in a population to deal with measurement uncertainty, and utilize Bayesian Model Averaging techniques to address uncertainty issues regarding model specification. My results indicate that while substantial data evidence favors the inclusion of population heterogeneity as a theory when proxied by fragmentation indices, it does not support the inclusion of this theory when proxied by polarization indices. Furthermore, the religious fragmentation index has the strongest evidence in favor of its inclusion as opposed to ethnic and linguistic fragmentation indices and income inequality.     

How do supply chain management and information systems practices influence operational performance? Evidence from emerging country SMEs

This study first provides a comparative analysis of the impact of supply chain management (SCM) and information systems (IS) practices on operational performance (OPER) of small- and medium-sized enterprises (SMEs) operating in two neighbouring emerging country markets of Turkey and Bulgaria. Then, we investigate moderating effects of both SCM–IS-linked enablers and inhibitors on the links between SCM and IS practices and OPER of SMEs. To this end, we first empirically identify the underlying dimensions of SCM and IS practices, and SCM–IS-related enabling and inhibiting factors. Second, a series of regression analyses are undertaken to estimate the impact of the study's constructs on OPER of SMEs. The results are discussed comparatively within the contexts of both Turkish and Bulgarian SMEs and beyond. The study makes a significant contribution to the extant literature through obtaining and analysing cross-national survey data of SCM and IS practices in emerging country markets.     

Democracy in the neighborhood and foreign direct investment

The determinants of foreign direct investment (FDI) have been extensively studied. Even though there is extensive research in the area, most of it is based on analyzing the effects of host country characteristics on FDI flows, and yet there is little research on how neighboring country characteristics play a role in facilitating FDI flows to host countries. This paper analyzes the association between the democracy level in neighboring countries and FDI flows to host countries. Using bilateral FDI flows from the OECD countries, with a large host country sample, we find that countries surrounded by democratic countries attract higher FDI flows. Furthermore, we find evidence that countries that are surrounded by neighboring countries with good institutions tend themselves to have better institutions, experience lower civil conflict, and have higher political stability and hence indirectly attract higher FDI flows. Our findings suggest that if neighboring countries act in such way as to become more democratic, FDI flows to these countries would be higher since not only does improving the quality of democracy attract more FDI inflows, but also being surrounded by neighboring advanced democratic countries will also lead to higher FDI flows to them.
