On the Comparison of Run Orders of Unreplicated 2<Superscript><Emphasis Type="Italic">k</Emphasis>–<Emphasis Type="Italic">p</Emphasis></Superscript> Designs in the Presence of a Time Trend

The response from a factorial experiment carried out in a time sequence may be affected by uncontrollable variables that are highly correlated with the time in which they occur. In such a situation, one possibility is to randomize the run order of the experiment. Another possibility is to use a systematic run order that is robust against time trends. Since randomized run orders make the time trend part of the error, it can be hoped that systematic run orders will be more effective to identify truly active factors. In this paper, a simulation study is used to compare the performances of the randomized and the systematic run orders. The response from an experiment where we have observed a strong time trend is used to demonstrate the influence of a realistic time trend on the run orders under consideration. The performance of the run orders is then measured by taking the probabilities of false rejection and the probabilities of detection of active contrasts. Our results show that the randomized run order managed to keep the nominal level, while the systematic did not. Additionally, when there were active factors, then the systematic run orders did not achieve more power than did the randomized run order.     

Nonparametric density estimates consistent of the order of <Emphasis Type="Italic">n</Emphasis><Superscript>−1/2</Superscript> in the <Emphasis Type="Italic">L</Emphasis><Subscript>1</Subscript>–norm

We introduce an approximate minimum Kolmogorov distance density estimate of a probability density f₀ on the real line and study its rate of consistency for n. We define a degree of variations of a nonparametric family of densities containing the unknown f₀. If this degree is finite then the approximate minimum Kolmogorov distance estimate is consistent of the order of n^–1/2 in the L₁-norm and also in the expected L₁-norm. Comparisons with two other criteria leading to the same order of consistency are given.Received June 2002     

Hotelling’s <Emphasis Type="Italic">T</Emphasis><Superscript>2</Superscript> control chart with two adaptive sample sizes

Some quality control schemes have been developed when several related quality characteristics are to be monitored. The familiar multivariate process monitoring and control procedure is the Hotelling’s T ² control chart for monitoring the mean vector of the process. It is a direct analog of the univariate shewhart [`(x)]{\bar{x}} chart. As in the case of univariate, the ARL improvements are very important particularly for small process shifts. In this paper, we study the T ² control chart with two-state adaptive sample size, when the shift in the process mean does not occur at the beginning but at some random time in the future. Further, the occurrence time of the shift is assumed to be exponentially distributed random variable.     

When the difference makes a difference – the regional embeddedness of entrepreneurship

Abstract

Regional determinants of new firm formation are of interest to researchers and policymakers. In the analysis of new firm formation, most studies use econometric approaches that mask intra-unit variations, not recognizing counterbalancing and dilution effects as a result. Recent advances in spatial statistics such as Geographically Weighted Regression (GWR) take local variations into account. However, these approaches operate only on a bivariate level, making it impossible to detect the homogenous parts of the area under examination with regard to a number of relationships between new firm formation and its determinants. Based on a sample of 412 German regions, we apply GWR and subsequent graph-partitioning clustering to identify multi-relationally homogeneous sub-areas. Being that the results suggest a four-cluster solution, ‘one size fits all’ policies and premature unit zoning can be called into question.     

Widening the ‘representation gap'? The implications of the ‘lobbying act’ for worker representation in the UK

The Transparency of Lobbying, Non‐Party Campaigning and Trade Union Administration Act 2014 (the ‘Lobbying Act’) imposes tight restrictions on the campaigning and lobbying activities of civil society organisations in the UK, diminishing their capacity to represent the interests of working people and thus likely compounding the ‘representation gap’ within British workplaces. Along with austerity measures and employment law reforms, the legislation exemplifies the UK government's attempts to shift the balance of power further towards employers.     

Forecasting clients’ reactions: How does the perception of strategic behavior influence the acceptance of advice?

Because they want high quality information, people often follow advice from advisors with high levels of expertise and confidence, and a reputation for accuracy. However, clients cannot always be sure that an advisor is actually using a knowledge advantage to act in the client’s best interests. In two studies we investigated the influence of an advisor’s perceived degree of self-interested intention on the client’s intention to accept and use their advice. We report two experiments in which clients received the same advice from a supposed representative of either a profit or a non-profit organization. The results of our first study suggest that clients who were confronted with an advisor from an organization with a profit-oriented background ascribed higher levels of self-interested intentions to the advisor and perceived the advisor to be less trustworthy. Furthermore, clients were less willing to rely on the advisor’s recommendation, and this effect was mediated by the perceived trustworthiness of the advisor. In our second study we conceptually replicated the findings of Study 1 using behavioral measures, and also differentiated three different facets of trustworthiness (competence, benevolence and integrity) in the interaction between advisor and client.     

Predictors of the adoption of work–care arrangements: a study of South African firms

This study examines predictors of work–care arrangements in South African organisations. It investigates the adoption of 23 work–care arrangements in organisations listed on the Johannesburg Stock Exchange. Organisational size, female presence in the organisation and in trade unions, female leadership and trade union density are tested as predictors of the adoption of these arrangements. In addition, foreign ownership, a previously untested variable predicting the adoption of work–care arrangements, is included in this study. The findings show that the level of adoption of work–care arrangements in South African organisations is low. Organisational size and female presence in senior managerial positions are found to be associated with the greater adoption of work–care arrangements. The study adds to existing work–family research by examining work–care integration in a non-Western context. Furthermore, the study is innovative in the addition of foreign ownership as an independent variable and the inclusion of a broader range of work–care arrangements in the study. The study is relevant for other developing nations and extends the existing research on employer involvement in work and care in developed nations.     

On the linearity of the wage–profit relation in a Sraffa’s model: a mathematical summing-up

This paper sums up in a common analytical structure the main results, scattered in economic literature, concerning the linearity between rate of profit and real wage in a simple Sraffa’s model. The paper is mainly based on previous results of one of the two authors and on results of Miyao (Int Econ Rev 18:151–162, 1977) and Schefold (Zeitschrift für angewandte Mathematik und Physik 27:873–875, 1976a; Zeitschrift für National?konomie 36:21–48, 1976b).     

The expatriate’s family as a stakeholder of the firm: a responsibility viewpoint

In this paper we argue for the recognition of the expatriate’s family as a stakeholder of the firm during the expatriation. We demonstrate why the expatriate’s family can be regarded as a stakeholder of the parent company and what kind of a stakeholder the family is. Additionally, we argue that the parent company needs to develop and apply a holistic well-being orientation to show stakeholder responsibility in the international assignment (IA) arena. We apply the theory of stakeholder salience to the IA relationship because it provides a theoretical framework for integrating the family into the expatriation process. Yet this theory does not necessarily provide a framework for assessing the social functioning of expatriates and their family members. Since expatriation often leads to a radical shift in family roles and living circumstances, family members (or indeed the expatriates themselves) cannot replicate all elements of their previous lives in the host country. Therefore, we use the capabilities approach to complete the theoretical framework, as this approach provides an evaluative mechanism which highlights how a socially responsible relationship between the company and the family can be advanced to foster well-being and quality of life for the family members as well as the expatriate, even if their functioning abroad differs from their functioning in their own country.     

Varieties of capitalism,neoliberalism and the economic crisis of 2008–?

This article examines the responses of national governments to the economic crisis that commenced in 2008. We argue that the current search for new bases for accumulation is leading to reforms designed to weaken the position of labour. Moreover, the tendency towards a weakening of labour's position was already evident across different ‘varieties of capitalism’ before the crisis erupted. We discuss the implications for comparative institutional analysis and stress the need for a renewed focus on the underlying dynamics of capitalist economies.     

Public servants’ workplace learning: a reflection on the concept of communities of practice

Workplace learning is not only for the purpose of improving work skills, but also of establishing linkages between different social resources. Scholars such as Lave and Wenger (Situated Learning: Legitimate Peripheral Participation, 1991) suggest that a community of practice (CoP) is formed by members’ common interests with a friendly informal atmosphere, within which the participants may feel free, to sharpen their skills and broaden their horizons. The concept of CoPs actually highlights the importance of using social resources to optimize the knowledge within the context of organization. However, because the learning situation is very informal, some scholars suggested that learning within a CoP may be too scattered to manage it well. For this study, the researchers use the concept of CoPs to examine public servants’ workplace learning and lay the focus on shared practices in the public sector in order to reflect on the concept of CoPs. The semi-structured interview method was employed, and most of viewpoints in this study were derived from 10 personnel departments in the public sector in Taiwan including 22 interviewees. The research supports the view that shared practices which are derived from the public servants’ daily official tasks are an important key to members’ informal learning. The concept of official tasks implies a compulsory atmosphere which enables related interactions to be compelled to happen. This will hopefully provide a solution for the loose discipline learning in CoPs.     

Who is ‘most valuable’? Measuring the player's production of wins in the National Basketball Association

How does one measure the productivity of an individual participating in a team sport? The purpose of this inquiry is to answer this question via an econometric model that links the player's statistics in the National Basketball Association (NBA) to team wins. This model will then be employed in the measurement of each player's marginal product. Such a measurement is useful in answering the question offered in the title, or a broader list of questions posed by both industry insiders and other interested observers.

The competitive advantage of cluster firms: the priority of regional network position over extra-regional networks – a study of a French high-tech cluster

This paper extends research on industry clusters by unbundling network from cluster effects and by analysing how network effects drive the performance of cluster firms. The results show that a firm's connectedness in a regional network is positively associated with firm performance. However, we found that for cluster firms, it is even more important to build strong network positions by developing rather exclusive alliance networks. In addition, a weak position within a cluster cannot be compensated for by strong extra-regional networking activities. From this perspective, cluster-specific advantages are firm-specific and the basis for competitive advantage. Regional competitiveness is therefore a non-substitutable pre-condition for the overall performance of cluster firms.     

The dynamics of entrepreneurs’ networks in a transitioning economy: the case of Russia

Despite its theoretical and practical importance, the evolution and development of entrepreneurs’ networks has attracted a little attention of researchers. The emerging research literature on this topic found that the dynamics of entrepreneurial networks were contingent upon venture lifecycle, industry and region, and resource needs of the firm. In addition and contrast to the previous research, this article examines the effects of the initial network structure, and firm performance of previous years on the changes in entrepreneurs' network structure, relations, and resources over 4 years. The empirical data is composed of the face-to-face interviews with 75 Russian entrepreneurs in 1995, and the follow-up interviews with 56 original respondents in 1999. I found that the greater the initial network size, the less the increase in network size, strong and weak ties, and resources over time. Further, the findings indicate that revenue growth of previous years predicts the changes in networks in the reverse manner. Thus, I found that the greater the average revenue growth, the less the increase in network size, weak ties, and resources over time.     

The role of wasta in repatriates’ perceptions of a breach to the psychological contract: a Saudi Arabian case study

This study examines the influence of a national cultural dimension, specifically a strong orientation towards collectivism/reliance on network relationships, referred to as ‘wasta’, on the way in which psychological contracts form and change in a Saudi organisation. Specifically, it focuses upon how the psychological contract is perceived to have been breached by repatriates because of the role that wasta plays in shaping formal and informal HR practices pre- and post-assignment. The analysis demonstrates that prior to international assignment, wasta was taken for granted and only implicitly acknowledged as influencing selection criteria for assignments and individuals’ expectations and obligations associated with their psychological contract. Once repatriated, wasta was foregrounded and perceived as highly problematic in terms of career advancement. This shaped repatriates’ perceptions that their psychological contract had been breached, influencing their intentions to leave. These findings suggest that the psychological contract can be viewed as highly context-specific, as well as a person-centred phenomenon. We consider the implications of our research in terms of the influence of national cultural characteristics on individual’s perceptions of breaches to the psychological contract and highlight the possible implications generally for Saudi Arabia, which is aiming to be less reliant on foreign labour.

Trust in the supervisor and the development of employees’ social capital during organizational entry: a conservation of resources approach

Abstract

This article aims to understand how trust in the supervisor contributes to the development of employees’ social capital using Conservation of Resources theory as a theoretical framework and networking ability as an indicator of social capital development. We hypothesize that the relationship between newcomers’ trust in the supervisor and networking ability will be mediated by feedback seeking from the supervisor and moderated by emotional exhaustion. Based on a three-wave time-lagged study of newcomers (N = 224), we found trust in the supervisor to be indirectly and positively related to networking ability through the mediating influence of feedback seeking from the supervisor. In addition, feedback seeking interacted with emotional exhaustion in predicting networking ability such that it was more positively related to it at high levels of emotional exhaustion. The indirect relationship of trust to networking ability as mediated by feedback seeking was also stronger at high levels of emotional exhaustion. We discuss this study’s implications for our understanding of supervisors’ role and newcomers’ experience during entry, as well as for social capital research.
