Halal value creation: its role in adding value and enabling logistics service

Abstract

The need to implement halal value creation into logistics and supply chains has been recognised recently. Yet, there is a lack of efforts to leverage resources and capabilities in contributing to the halal value creation for competitive advantage and subsequently firm performance. The purpose of this paper is to understand the halal value creation of current practices and its role in adding value and enabling logistics service. A structure interview of seven third-party logistics (3PL) providers is conducted to provide more precise perception about works by viewing with the lens prescribed by practitioners rather than reviews. The results draw the novel practices of halal value creation in logistics, that have not been revealed and further identifies five emerging resources of ‘resource-based halal logistics’. These create innovation capability (ability to launch successful halal goods/services) in logistics services, which are transformed into benefits of profits for 3PLs and value for customers.     

Livelihood Assets and Vulnerability Context of Marine Park Community Development in Malaysia

This study assesses the community’s standard of living using the well-known Sustainable Livelihood Approach (SLA) as an analytical framework within the Marine Park Areas (MPAs) in Peninsular Malaysia. We focus on livelihood sustainability and environmental issues challenging MPAs. In order to protect and conserve vulnerable marine life, our efforts assess the residents’ wellbeing and identify major environmental issues associated with MPAs. The major findings of this study indicate that social and physical assets of the societies within the Marine Park Island improved with economic development, but they continue to lack in human capital, and financial and environmental assets. It is expected that this study would assist policy makers to formulate enhanced policies for conserving marine diversity as well as to improve the socio-economic status of the communities that reside therein.     

Regression model for surrogate data in high dimensional statistics

Abstract

This paper deals with the problem of estimating the regression of a surrogated scalar response variable given a functional random one. We construct an estimator of the regression operator by using, in addition to the available (true) response data, a surrogate data. We then establish some asymptotic properties of the constructed estimator in terms of the almost-complete and the quadratic mean convergences. Notice that the obtained results generalize a part of the results obtained in the finite dimensional framework. Finally, an illustration on the applicability of our results on both simulated data and a real dataset was realized. We have thus shown the superiority of our estimator on classical estimators when we are lacking complete data.     

Multivariate analysis of parity progression—based measures of the total fertility rate and its components

This article describes a methodology for applying a discrete-time survival model—the complementary log-log model—to estimate effects of socioeconomic variables on (1) the total fertility rate and its components and (2) trends in the total fertility rate and its components. For the methodology to be applicable, the total fertility rate (TFR) must be calculated from parity progression ratios (PPRs). The components of the TFR are PPRs, the total marital fertility rate (TMFR), and the TFR itself as measures of the quantum of fertility, and mean and median ages at first marriage and mean and median closed birth intervals by birth order as measures of the tempo or timing of fertility. The focus is on effects of predictor variables on these measures rather than on coefficients, which are often difficult to interpret in the complex models that are considered. The methodology is applicable to both period and cohort data. It is illustrated by application to data from the 1993, 1998, and 2003 Demographic and Health Surveys (DHS) in the Philippines.     

Job demands and work-related psychological responses among Malaysian technical workers: The moderating effects of self-efficacy

Abstract

Job design has long been found to affect the work-related psychological responses of employees, such as psychological strain, job satisfaction, and turnover intentions, but scholars have begun to question whether established theoretical relations regarding job design continue to hold given the enormous changes in the nature of work during the past two decades. It is also increasingly recognized that individual differences affect work behaviours in substantial ways, but few studies on work design have investigated these differences. We addressed these concerns with a two-wave longitudinal study among 245 technical workers at a telecommunications company in Malaysia, a country that has a collectivist culture and a high power distance between managers and subordinates. We examined the moderating effects of job control and self-efficacy on the relationships between job demands and employee responses. The results failed to support the job demands-control model, as job control variables did not moderate the impact of demands on employee work-related psychological responses. However, self-efficacy moderated their impact on psychological strain (although not on job satisfaction or turnover intentions). Our findings provide insight into the moderating effect of self-efficacy, and suggest that practitioners interested in reducing psychological strain should consider making efforts to increase self-efficacy among employees.     

On the wald,lagrangian multiplier and likelihood ratio tests when the information matrix is singular

Summary Modified formulas for the Wald and Lagrangian multiplier statistics are introduced and considered together with the likelihood ratio statistics for testing a typical null hypothesisH ₀ stated in terms of equality constraints. It is demonstrated, subject to known standard regularity conditions, that each of these statistics and the known Wald statistic has the asymptotic chi-square distribution with degrees of freedom equal to the number of equality constraints specified byH ₀ whether the information matrix is singular or nonsingular. The results of this paper include a generalization of the results of Sively (1959) concerning the equivalence of the Wald, Lagrange multiplier and likelihood ratio tests to the case of singular information matrices.     

Strategic Management in the Public Sector: Reflections on It’s Applicability to Iranian Public Organizations

Strategic management is a managerial story of private sector that has been transferred to the public sector. Many authors have challenged its applicability in public organizations. This paper discusses some important barriers to implementation of strategic management in the public sector empirically. After presenting a conceptual model, we examine several important factors that influence the failure or shortcomings of public sector strategic management. The last section of paper offers implications for theory and practice.     

Victimization in young urban adults and depressed mood: understanding the interplay of coping and gender

Violence exposure has a significant impact on victims' psychological well-being. This study examined the relationship between two types of violence exposures (threats and physical assaults), coping styles (emotion focused, avoidant, and problem focused), gender, and depression among 211 (147 females and 64 males) young urban adults (ages 18-24). Most participants (60%) endorsed being physically assaulted, whereas many (40%) endorsed being threatened. Hierarchical multiple regressions were conducted. As hypothesized, women reported using more emotion-focused coping and reported greater depression than men. Avoidant coping was a predictor for increased depression for both men and women. However, women who employed problem-focused coping after their first physical assault reported lower rates of depression. These findings have implications for designing early interventions.
