Emerging managerial competencies of professionals in the Tanzanian construction industry

The managerial competencies required by professionals in the construction industry in Tanzania to operate effectively in a business environment which is changing as a result of a transition from a socialist to a free-enterprise economy, economic liberalization, globalization and regionalization are explored through a qualitative study. The study reveals that local Tanzanian construction firms are finding it difficult to compete with foreign companies for projects. This is mainly because Tanzanian professionals lack the competencies required to compete and manage projects in a liberalized market economy.

The study thus highlights the need for Tanzanian construction professionals to acquire a better grasp of both occupational and organizational competencies. In this respect, it is suggested that they need post-experience training in order to acquire the competencies required to function successfully in a commercial environment.     

Internationalization of multi-source feedback systems: a six-country exploratory analysis of 360-degree feedback

In the past few years, few human resource practices have received as much attention as multi-source feedback systems (MSFSs). In the US and Canada, it is estimated that over one-third of organizations are using some form of MSFS and recent surveys show that this practice is still gaining popularity. Concurrently, a substantial amount of literature has focused on the effectiveness of this performance management practice. However, while few would dispute the popularity of MSFS, relatively little has been published on the use of these systems outside North America and thus little is known about their form and effectiveness in international contexts. This paper outlines the results of an international survey of MSFS. Interview data from HR managers and consultants from Argentina, Australia, China, Slovakia, Spain and the UK demonstrate that MSFS are being implemented, in slightly different ways, in each of these six countries. The main challenges in the application of MSFS in these various countries are the communication efforts necessary before and after implementation, and the inherent difficulty in giving and receiving feedback. The results of this study also provide data as to the perceived future of MSFS in each of the countries surveyed.     

Gender,family ties,and international mobility: Cultural distance matters

This study empirically tests a model of associations between family-domain variables and willingness to accept an international assignment, and applies the general model to sub-samples of men and women to examine gender differences in the pattern of relationships. We further explore these patterns in culturally similar and culturally distant country destinations. Analyses conducted with a sample of 148 men and 79 women employed MBA graduates from dual-earner couples revealed that perceived spouse willingness to relocate, beliefs regarding spouse and couple mobility, relative income, and the presence of children are associated with willingness to accept an international assignment. Moreover, consistent with social role theory, significant gender differences in willingness were found across low and high cultural distance country destinations.     

Employee commitment in MNCs: Impacts of organizational culture,HRM and top management orientations

This article tests a model of organizational commitment in multinational corporations (MNCs). According to the model, organizational culture and human resource management (HRM) affect employee commitment directly as well as indirectly through top management team orientations. Szpecifically, we examined the effect of top management team global orientation and geocentric orientation, which are seen as contributing uniquely to employee commitment in MNCs. The model was tested on a sample of 1664 core employees working in 39 affiliates of 10 MNCs. We found strong overall support for the model. In particular, organizational culture characterized by high adaptability and a HRM system characterized by high performance work practices were found to have a significant and direct effect on employee commitment. In addition, we found that the effect of these traditional elements of the human organization is partially mediated through top management orientations, specific to international firms. The validity and generalizability of these results are reinforced by the control of a set of demographic variables as well as nationality of parent company.     

Could HRM support organizational innovation?

Nowadays, it has become clear that the capacity of organizations to innovate and manage their human resources can be sources of competitive advantage. Recently, literature also asserts a positive relationship between human resource management and innovation. However, very little empirical research has specifically addressed those relationships. Using structural equations modelling with data collected from 173 Spanish firms, this study analyses them. Our findings show that innovation contributes positively to business performance and that human resource management enhances innovation. Implications for both academics and managers as well as future research lines are discussed.     

Expatriate adjustment from the inside out: an autoethnographic account

This paper identifies some of the dynamics of expatriate adjustment using an autoethnographic account of situations experienced by the first author during her first year of work at a financial services company in Hong Kong. Success in this cross-cultural assignment is dependent on the expatriate's ability to adjust to and master the new culture. Our theoretical analysis of the autoethnographic account suggests that culture shock may be a discontinuous process. Further, the analysis suggests that cultural acceptance can play a critical role in expatriate adjustment.     

Convergence and performance of the peeling wavelet denoising algorithm

This note is devoted to an analysis of the so-called peeling algorithm in wavelet denoising. Assuming that the wavelet coefficients of the useful signal are modeled by generalized Gaussian random variables and its noisy part by independent Gaussian variables, we compute a critical thresholding constant for the algorithm, which depends on the shape parameter of the generalized Gaussian distribution. We also quantify the optimal number of steps which have to be performed, and analyze the convergence of the algorithm. Several implementations are tested against classical wavelet denoising procedures on benchmark and simulated biological signals.     

Corporate hyperlink network relationships in global corporate social responsibility system

This study analyzed the hyperlink (co-link) network structure among companies in global Corporate Social Responsibility (CSR) system. This study measured network variables such as density and centrality, including degree centrality, eigenvector centrality, closeness, and betweenness. The results indicated that European companies had relatively central roles in the global CSR system. In addition the higher performing companies are more active their CSR practices. Also, the results revealed that the industrial type of companies was not significantly associated with its CSR practices.     

Double symmetry model and its decompositions in square contingency tables having ordered categories

In this paper, we have employed the non-standard log-linear models to fit the double symmetry models and some of its decompositions to square contingency tables having ordered categories. SAS PROC GENMOD was employed to fit these models although we could similarly have used GENLOG in SPSS or GLM in STATA. A SAS macro generates the factor or scalar variables required to fit these models. Two sets of \(4 \times 4\) unaided distance vision data that have been previously analyzed in (Tahata and Tomizawa, Journal of the Japan Statistical Society 36:91–106, 2006) were employed for verification of results. We also extend the approach to the Danish \(5 \times 5\) Mobility data as well as to the \(3 \times 3\) Danish longitudinal study data of subjective health, firstly reported in (Andersen, The Statistical Analysis of Categorical Data, Springer:Berlin, 1994) and analyzed in (Tahata and Tomizawa, Statistical Methods and Applications 19:307–318, 2010). Results obtained agree with those published in previous literature on the subject. The approaches suggest here eliminate any programming that might be required in order to apply these class of models to square contingency tables.
