Differentiation in leader–member exchange: A hierarchical linear modeling approach

This paper explores possible antecedents and consequences of leader–member exchange (LMX) differentiation. LMX differentiation is a group-level construct, defined as the degree to which members working with the same leader differ in terms of their LMX relationship quality with their leader. Specifically, we hypothesize that leaders’ personal universalistic values are negatively correlated with LMX differentiation. LMX differentiation, in turn, moderates the lower-level effect that LMX has on performance evaluation. Using surveys from leaders and subordinates as well as archival data from six companies, we found support for these arguments. However, we did not find support for a hypothesized cross-level moderation effect of differentiation on the effect LMX has on interactional justice. Implications for theory and discussion of future research directions are also addressed.     

Accountability and value for money: a theoretical framework for the relationship in public–private partnerships

There is an implicit assumption in the UK Treasury’s publications on public-private partnerships (PPP)—also more commonly known in the United Kingdom as private finance initiative (PFI)—that accountability and value for money (VFM) are related concepts. While recent academic studies on PPP/PFI (from now on as PFI) have focused on VFM, there is a notable absence of studies exploring the ‘presumed’ relationships between accountability and VFM. Drawing on Dubnick’s (Dubnick and Romzek in American public administration, politics and the management of expectations. Macmillan, New York, 1991, Research in public administration. JAI, Greenwich, 1993; Dubnick in Public service ethics and the cultures of blame, 1996, Public sector ethics: finding and implementing values. Routledge, London, 1998, Int J Org Theory Behav 6(3):405–441, 2003, Public Perform Manage Rev 28(3):376–417, 2005; Dubnick and Justice in But can you trust them to be ethical, 2002) framework for accountability and PFI literature, we develop a research framework for exploring potential relationships between accountability and VFM in PFI projects by proposing alternative accountability cultures, processes and mechanisms for PFI. The PFI accountability model is then exposed to four criteria—warrantability, tractability, measurability and feasibility. Our preliminary interviews provide us guidance in identifying some of the cultures, processes and mechanisms indicated in our model which should enable future researchers to test not only the UK Government’s claimed relationships between accountability and VFM using more specific PFI empirical data, but also a potential relationship between accountability and performance in general.     

Transnational marketing joint ventures: a viable market penetration strategy in the EU?

This article investigates the performance of EU-based transnational marketing joint ventures (MJVs) through a set of case studies. The results emphasise the instability inherent in MJVs, and in most cases instability reflected poor performance rather than the evolution of a successful venture in the foreign market. Companies were found to undertake MJVs in order to protect and control existing market positions in the foreign country rather than gain access. Little attempt was made to transfer knowledge and expertise between the partners. Under these conditions instability resulted in the failure of the parent company to achieve its primary objective: the protection of marketing assets in the foreign market. Exporters should consider mechanisms through which local expertise can be transferred within the MJV.     

Half integer extreme points in the linear relaxation of the 2-edge-connected subgraph polyhedron

This paper studies the graphs for which the linear relaxation of the 2-connected spanning subgraph polyhedron has integer or half-integer extreme points. These graphs are called quasi-integer. For these graphs, the linear relaxation of the k-edge connected spanning subgraph polyhedron is integer for all k=4r, r≥1. The class of quasi-integer graphs is closed under minors and contains for instance the class of series-parallel graphs. We discuss some structural properties of graphs which are minimally non quasi-integer graphs, then we examine some basic operations which preserve the quasi-integer property. Using this, we show that the subdivisions of wheels are quasi-integer.     

The role of the board in shaping foundations’ strategy: an empirical study

This paper investigates the relationships of the choice of philanthropic strategy with board capital (diversity and networks), board activities (board processes, internal board committees, and board effectiveness), and CEO leadership. Using a sample of 110 Italian foundations, the research shows that board processes have the strongest positive association with an evolved strategic approach to philanthropic institutional grant-giving, while board diversity and strong CEO leadership are associated with the strategic approach only under certain conditions. In particular, good governance processes (e.g., training the board, self-evaluation of trustees, setting the stage for effective board and committee meetings, implementing control software, and steering meetings to improve the board’s analysis) are positively associated with evolved strategic approaches to philanthropy (e.g., signaling other funders for the best grantees, improving the performance of grant recipients, and advancing selected social fields’ state of knowledge and practice).     

Human resource strategy to improve organizational performance: a route for firms in Britain?

Performance, in the context of organization, is not only a broad concept which has been used synonymously with productivity, efficiency, effectiveness and, more recently competitiveness, it has also been a subject of study for social scientists from a wide range of disciplinary perspectives. More recently, efforts have been made by human resource management (HRM) theorists to try to establish a causal link between HRM and performance. This has led to a growing number of studies which examine the potential contribution that good human resource policy can make to improving organizational performance. This paper is not concerned with the conceptual debate of HRM and performance. Rather, it explores whether adopting good HR practices to improve performance is a practicable approach to organizations in the UK. Drawing on existing empirical evidence from other studies, the paper reviews the strategies British firms deploy to improve labour productivity. In particular, the issue of whether they use the 'high-road' HRM or 'low-road' HRM strategy to enhance performance is investigated. This paper concludes by suggesting that high-road HRM may lead to better organizational performance, but it may not be a strategy that firms opt for, given the historical, social and institutional context of employment relationships in Britain.     

Paving the way for coopetition: drivers for work–life balance policy implementation

An extensive literature provides evidence that conflict between employees’ family and work duties is associated with stress and poor well-being, which have negative consequences for firms and their employees. This paper analyzes the role of two internal and two external drivers that encourage (or discourage) organizations to adopt and implement work–life balance policies. The role of external financial assistance and specific laws (external drivers), together with budgetary provision for work–life balance policies and managers’ perceptions regarding problems due to work–life conflict (internal drivers), are analyzed. Fuzzy-set qualitative comparative analysis is used to pursue the study’s research goals. Analysis of data on 132 SMEs suggests that financial issues (external financial assistance and/or a specific budget within the company) are key factors for the implementation or lack of implementation of work–life balance policies. Moreover, to implement these policies, managers need not necessarily perceive problems due to work–life conflict. Finally, work–life balance legislation seems not to play an explicit role in the relationships discussed herein. Consequences of these findings are discussed in the final section of the paper.     

“Modest doubt is called the beacon of the wise”—Incorporating uncertainty in risk analysis from Shakespeare to today

“Modest doubt is call'd the beacon of the wise.”—William Shakespeare, Troilus and Cressida. Although the character Hector warns his fellow Trojans with this line not to engage in war against the Greeks, Shakespeare's works are replete with characters who do not incorporate modest doubt, or any consideration of uncertainty, in their risk decisions. Perhaps Shakespeare was simply a keen observer of human nature. Although risk science has developed tremendously over the last five decades (and scientific inquiry over five centuries), the human mind still frequently defaults to conviction about certain beliefs, absent sufficient scientific evidence—which has effects not just on individual lives, but on policy decisions that affect many. This perspective provides background on the Shakespearean quote in its literary and historical context. Then, as this quote is the theme of the 2023 Society for Risk Analysis Annual Meeting, we describe how “modest doubt”—incorporating the notion of uncertainty into risk analysis for individual and policy decisions—is still the “beacon of the wise” today.     

An empirical examination of the science–technology relationship in the biotechnology industry

Understanding how a firm's scientific capability influences its technology development has important implications on the firm's research and development (R&D) strategies. However, the current literature reveals a puzzling outcome in its empirical investigations on the science–technology relationship. While many studies show the positive influence of a firm's scientific capability on its technological performance, a few others indicate that if a firm focuses its attention more on cutting edge science, its overall technological performance will suffer. We suggest that these findings can be reconciled by conceptualizing and measuring the scientific capability of the firm differently. This paper attempts to demonstrate how different notions of scientific capability are associated with different performance outcomes. Furthermore, a firm's scientific capability facilitates the integration of new knowledge to produce valuable technologies when a firm broadens its search for new knowledge. The paper highlights the nuances of conceptualizing and measuring the firm's scientific capability in two different ways: number of scientific publications and non-patent references. The findings also shed light on the mechanism through which science accelerates technological progress inside a firm.     

Nordhaus–Gaddum type result for the matching number of a graph

For a graph G, \(\alpha '(G)\) is the matching number of G. Let \(k\ge 2\) be an integer, \(K_{n}\) be the complete graph of order n. Assume that \(G_{1}, G_{2}, \ldots , G_{k}\) is a k-decomposition of \(K_{n}\). In this paper, we show that (1)

$$\begin{aligned} \left\lfloor \frac{n}{2}\right\rfloor \le \sum _{i=1}^{k} \alpha '(G_{i})\le k\left\lfloor \frac{n}{2}\right\rfloor . \end{aligned}$$

(2) If each \(G_{i}\) is non-empty for \(i = 1, \ldots , k\), then for \(n\ge 6k\),

$$\begin{aligned} \sum _{i=1}^{k} \alpha '(G_{i})\ge \left\lfloor \frac{n+k-1}{2}\right\rfloor . \end{aligned}$$

(3) If \(G_{i}\) has no isolated vertices for \(i = 1, \ldots , k\), then for \(n\ge 8k\),

$$\begin{aligned} \sum _{i=1}^{k} \alpha '(G_{i})\ge \left\lfloor \frac{n}{2}\right\rfloor +k. \end{aligned}$$

The bounds in (1), (2) and (3) are sharp. (4) When \(k= 2\), we characterize all the extremal graphs which attain the lower bounds in (1), (2) and (3), respectively.

     

Uncertainty in competitive bidding – a framework for product–service systems

Owing to servitisation, manufacturing companies are increasingly required to compete through the provision of services around their products. The contracts for these services are often allocated through competitive bidding where the potential suppliers submit a price bid to the customer. The pricing decision is influenced by various uncertainties. This article proposes a conceptual framework depicting these influencing uncertainties on the bidding strategy. This framework is based on three empirical studies with industry investigating different viewpoints on the decision-making process. The intention is to support the pricing decision when competitively bidding for a service contract. The framework can be applied to specific competitive bidding situations to identify the influencing uncertainties, model them and depict their influences on the pricing decision.     

Planning for the older manager— Collaborative research in Norwegian business

This action learning/action research project involves 12 of Norway's largest companies who have committed themselves to study upward and downward management mobility. Two larger reports have been completed, one in Norwegian and one in English. New projects are being started with groups of companies in Sweden and the Federal Republic of Germany with a possibility of other projects in the United States, England and Denmark. This paper represents a brief summary of the project and is divided into two parts. In the first part the four phases of the project are reviewed, including both quantitative and qualitative methodologies. The second part contains some of the results obtained.     

Hierarchical production planning for multi-product lines in the beverage industry¶

Multi-commodity production and distribution scheduling is one of the most complex and crucial problems facing many manufacturing companies. For a major European manufacturer specialising in bottling juices and drinks, we have designed and developed a hierarchical decomposition approach to the solution of the multi-commodity production planning problem. In this paper we focus our attention on the coarsest decomposition level, called multi-commodity aggregate production planning (MCAP). It concerns the choice of the best feasible production plan for a set of products (commodities) over an extended time horizon so as to meet forecast aggregate demands throughout the horizon. At this level, the problem constraints include hard constraints (such as production lines having a maximum capacity and products having short life-times), and soft constraints (budgetary concerns.) The objective is to determine the production plan that covers each period's demands as best as possible, while minimizing all relevant costs. Our method for solving MCAP produces optimal plans in negligible times in commodity PC workstations.     

Narrowing the gap—Equal Pay in Britain 1970–1986

In 1970, Britain introduced the Equal Pay Act aiming at eliminating wage differentials between women and men employed on the ‘same’ or ‘like’ work. Later, the European Communities Commission took infringement proceedings against Britain on the grounds that the equal Pay Act (1970) did not fully implement the European Community directive on the principle of equal pay for work of ‘equal value’. As a result, an amendment was introduced in 1984 to cover also the latter requirement. This paper focuses on the effects of the original Act upon female pay. It concludes that female pay increased significantly during the 1970s because of the Equal Pay Act (1970). The impact of legislation is then attributed to the peculiar way of female wage determination before equal pay was introduced rather than to the sophistication of the Act.     

Estimating Evacuation Shelter Deficits in the Houston–Galveston Metropolitan Area

Evacuation is frequently used by emergency managers and other officials as part of an overall approach to reducing the morbidity and mortality associated with hurricane landfall. In this study, the evacuation shelter capacity of the Houston–Galveston Metropolitan Statistical Area (MSA) was spatially assessed and shelter deficits in the region were estimated. These data provide essential information needed to eliminate shelter deficits and ensure a successful evacuation from a future storm. Spatial statistical methods—Global Moran's I, Anselin Local Moran's I (Local Indicators of Spatial Association [LISA]), and Hot Spot Analysis (Getis-Ord Gi*) were used to assess for regional spatial autocorrelation and clustering of evacuation shelters in the Houston–Galveston MSA. Shelter deficits were estimated in four ways—the aggregate deficit for the Houston–Galveston MSA, by evacuation Zip-Zone, by county, and by distance or radii of evacuation Zip-Zone. Evacuation shelters were disproportionately distributed in the region, with lower capacity shelters clustered closer to evacuation Zip-Zones (50 miles from the Coastal Zip-Zone), and higher capacity shelters clustered farther away from the zones (120 miles from the Coastal Zip-Zone). The aggregate shelter deficit for the Houston–Galveston MSA was 353,713 persons. To reduce morbidity and mortality associated with future hurricanes in the Houston–Galveston MSA, authorities should consider the development and implementation of policies that would improve the evacuation shelter capacity of the region. Eliminating shelter deficits, which has been done successfully in the state of Florida, is an essential element of protecting the public from hurricane impacts.     

Opportunism in buyer–supplier exchange: a critical examination of the concept and its implications for theory and practice

Abstract

Claims that opportunism is widespread in the process of buyer–supplier exchange are commonplace, but direct supporting evidence for such claims is largely absent from the relevant literature. This article offers a critique of the treatment of opportunism in supply chains by re-establishing the importance of guile in the concept and investigates existing published, empirical measures of buyer and supplier opportunistic behaviour. This article offers evidence that, despite the frequency with which the concept is discussed in the literature and applied in research and the emphasis given to the risks it generates for management, opportunism with guile between buyers and suppliers appears to be rare in practice. This article is the first critical assessment of the concept’s treatment in the Operations Management field, and it argues that practitioners are currently being poorly advised with respect to the phenomenon, as well as drawing conclusions for both practitioners and researchers that differ radically from the prevailing consensus on the subject.     

Is Imperfect Competition in the Product Market Relevant for Labour Markets?

Recent research in macroeconomics emphasises the importance of imperfect competition in the product market for labour market outcomes. We investigate one aspect of this issue by specifying a dynamic labour demand model where firms face different degrees of competition in the product market and test its predictions for 299 US manufacturing industries. We find that the long-run equilibrium level of industry employment as well as the speed of labour demand adjustment decreases with market power. Our results imply that imperfect competition in the product market explains part of the observed labour market rigidities and also sheds new light on two “stylized facts” in industrial organisation, the observation of procyclical movements in productivity and price–cost margins in concentrated industries.     

Part-Time Work in the Nordic Countries: A Trap for Women?

Abstract. The aim of the study is to examine the consequences of part-time employment at the individual level, especially for women. Are part-time jobs precarious as compared to full-time jobs, and are they traps, or perhaps rather bridges, in the labour market? The results indicate that the situation of part-timers varies in the Nordic countries. On one hand, the gap between part-time and full-time work has narrowed in Sweden and Norway, which may reflect a normalization of part-time work in these countries. On the other, part-timers' situation in the Finnish labour market still seems more precarious than that of full-timers. However, in most cases part-time work is a bridge rather than a trap in the Nordic labour market.
