This paper discusses the 'social' nature of employment management problems in sub-Saharan Africa (SSA). 'Applied' Western HRM is largely based on unitarist conceptions of organizational reality. Where conceptions suggest a 'stakeholder' perspective, they tend to follow orthodox formulations of pluralism. In that regard, notions of 'stakeholding' refer to the divergent internal organizational interests (mainly economic) of labour and management. In the SSA context, however, the broader social and moral issues of the wider community have a decisive influence on the employment relationship. And internal employment relations structures, such as trade unions, do not constitute the main representative channels for employee grievances. Consequently, established Western employment frames of reference do not represent suitable theoretical frameworks for analysing all the relevant social factors that influence the SSA employment relationship. This paper proposes a modified version of Ackers' (2002) 'neo-pluralist' theoretical framework as the basis for understanding and resolving some of issues involved in HRM in SSA. From this analysis, it proposes a model of HRM that attempts to institutionalize some elements of the 'African social system' into formal HRM policies and strategies.  相似文献

The problem of allocating the sample numbers to the strata in multivariate stratified surveys, where, apart from the cost involved in enumerating the selected individuals in the sample, there is an overhead cost associated with each stratum, has been formulated as a non-linear programming problem. The variances of the posterior distributions of the means of various characters are put to restraints and the total cost is minimized. The main problem is broken into subproblems for each of which the objective function turns out to be convex. When the number of subproblems happens to be large an approach has been indicated for obtaining an approximate solution by solving only a small number of subproblems.  相似文献

This paper complements prior studies on the public accounts committees (PACs) by considering the notions of ‘agency’ and ‘structure’ of institutional theory in tandem in understanding the changes in structures and activities of the PAC of a less‐developed democratic country – Bangladesh. While prior studies examined ‘external’ institutional pressures on the development and operation of the PAC in various settings, the role of internal and external institutional agents in this context has not been their primary focus. Our empirical evidence from a qualitative field study indicates that over the past two decades, Bangladesh's PAC underwent significant changes to its internal governance structures and administrative processes. While these changes were indirectly driven by pressures from international donor agencies, PAC members and the national audit office played a key role as institutional agents in initiating and institutionalising the changes in PAC governance and operation.  相似文献

This paper investigates the dynamic relationships between research and development (R&D) expenditure and productivity growth in Australian broadacre agriculture using aggregate time series data for the period 1953 to 2009. The results show a cointegrating relationship between R&D and productivity growth and a unidirectional causality from R&D to TFP (total factor productivity) growth in Australian broadacre agriculture. Using the dynamic properties of the model, data from beyond the sample period are analysed by employing the variance decomposition and the impulse response function. The findings reveal that R&D can be readily linked to the variation in productivity growth beyond the sample period. Furthermore, the forecasting results indicate that a significant out‐of‐sample relationship exists between public R&D and productivity in broadacre agriculture.  相似文献

The purpose of this study was to explore the relationship between online reviews and ratings through text mining and empirical techniques. An Indian food delivery portal ( Zomato.com ) was used, where 50 restaurants on Presence Across Nation (PAN) basis were selected through stratified random sampling. A total of 2530 reviews were collected, scrutinized, and analysed. Using the NVivo software for qualitative analysis, seven themes were identified from collected reviews, out of which, the ‘delivery’ theme was explored further for identifying sub-themes. Linear regression modelling was used to identify the variables affecting delivery ratings and sentiment analysis was also performed on the identified sub-themes. Regression results revealed that hygiene and pricing (delivery subthemes) demonstrated lower delivery ratings. These variables can be established as indicators for restaurants and related online food delivery services to build their business model around them. Similarly, negative sentiments were observed in pricing and hygiene sub-themes. Restaurants and online food services can enhance hygiene levels of their food delivery process in order to receive higher delivery ratings. Similarly, pricing of food items can be modified such that customers are not deterred from ordering the items—food and ordering service do not become cost-prohibitive. This study devised a standardized methodology for analysing vast amounts of online user-generated content (UGC). Findings from this study can be extrapolated to other sectors and service industries such as, tourism, cleaning, transportation, hospitals and engineering especially during the pandemic.  相似文献

We investigate the economic feasibility of bioelectricity production from biomass in Malaysia and its impact on greenhouse gas (GHG) emissions and storage, agricultural prices, agricultural employment and deforestation. For this purpose, we develop a partial equilibrium model that projects agricultural prices, production, imports, exports, domestic consumption and land use in 5‐year increments between 2015 and 2065. Our results show that by 2030 biomass‐generated electricity can supply 36.5 per cent of the electricity generated in Malaysia, 16 times more than the 2016 electricity supply from biomass. Increased bioelectricity production from biomass will significantly reduce GHG emissions and will help Malaysia meet its commitment in the Paris Agreement to mitigate GHG emission by 45 per cent before 2030. Our modelling shows that biomass‐generated electricity creates a derived demand for waste biomass that expands the area of oil palm plantations. The expansion lowers agricultural prices, boosts agricultural employment and leads to some deforestation as landowners clear rainforest to plant oil palm trees. Nonetheless, the deforestation does not increase GHG emissions since GHG gains from bioelectricity significantly exceed GHG losses from deforestation.  相似文献

The global growth of Islamic banking is taking advantage of the diversity and flexi‐bility in the fiqh opinions (often referred to as Shariah) to meet the challenges of growth. While the flexibility in fiqh opinion is presently contributing to global growth, it may soon become a constraining factor in the global growth of the industry if the challenges arising out of the use of diversity and flexibility in fiqh are not properly rec‐ognized and regulated. Though the infrastructure for standardizing the supervision and monitoring of the global expansion of the Islamic finance industry is rapidly growing, institutional arrangement for a regulated use of diversity and flexibility in Shariah rules is still a missing link. Such an institutional arrangement is needed not only to prepare the industry to play a bigger role in the development of global economy but also to ensure the adherence to the very specific element that makes the industry an “Islamic” industry. © 2007 Wiley Periodicals, Inc.  相似文献

Introduction

The study examines the importance of intertemporal substitution in import demand considering the role of habit formation. A two-goods version of the permanent income model is used in which time-non-separability in consumers’s preferences is assumed. The model is estimated using annual data for Pakistan at disaggregated level covering the period from 1977 to 2017.

Objectives

The objective of the study is to estimate elasticities of substitution along with parameters of habit formation for consumption goods at a disaggregated level.

Method

The study employs co-integration for the estimation of parameters of elasticities of substitution and generalized method of moments (GMM) for the estimation of the parameters of habit formation from Euler equations.

Findings

The estimates of intertempral elasticity of substitution suggest that the nature of commodity group (necessity/luxury) plays an important role when consumers are making intertemporal choices. Moreover, the study finds that intratemporal elasticity of substitution is larger than intertempral elasticity of substitution in almost all cases in Pakistan, suggesting that imported and domestic goods are best described as substitutes in Edgeworth-Pareto sense. In addition, the inclusion of habit formation delivers results with plausible signs and the habit formation process seems significant for certain commodity groups including tea, beverages, tobacco products and drugs.

Conclusion

The study concludes that there is a possibility of crowding out effect on domestic consumption and the depreciation of local currency may improve Pakistan’s balance of trade.

This article investigates how the response to devaluation of trade balance is affected, compared to J-curve hypothesis, by the presence of imported inputs in the production of exports. Using first the Almon lag technique and then the cointegration and the generalized impulse response function analysis, the J-curve effect is examined in two sectors of Turkish economy (manufacturing and mining), which use imported inputs at different rates. Based on the data covering the period from the first quarter of 1986 to the third quarter of 1998, our results indicate that in neither sector J-curve exists and that the violation of the J-curve effect is more severe in the sector with higher import content  相似文献
