Dubai in the ‘Middle’

In the early 2000s, Dubai seemed the apotheosis of the global city model. Lauded as an embodiment of globalist ideals, or harshly criticized as a representation of the dangers of contemporary urbanism, it was clearly under the spotlight. Then, like the concept of the ‘global city’ itself, it disappeared from the headlines, to be subject only to sporadic and cynical attention. Today some are heralding a ‘return’ of Dubai from the anonymity of the middle ground of global city hierarchies and rankings. What is often forgotten, however, is that urbanism in Dubai did not stop. On the contrary, Dubai's continuous ‘worlding’ offers a productive opportunity for the encounter of ‘global’ and ‘ordinary’ modes of urban analysis. By unpacking the construction of a global Dubai, this article advocates greater sensitivity to the multiscalar politics that shape its continuity. Stepping beyond rumours of crisis and decline, it aims to connect the global fortunes and everyday processes that jointly characterize the development of global cities. ‘Global’ and ‘ordinary’ urbanism, it argues, are but two registers of how we could, in Warren Magnusson's words, ‘see like a city’.     

Social Intermediation in Base‐of‐the‐Pyramid Markets

Our study explores the structuring decisions made by intermediaries seeking to alleviate poverty by connecting base‐of‐the‐pyramid markets with more developed markets. Using intermediation theory to ground our study, we collected qualitative data on 29 social intermediation projects located within Latin America, Africa, and Asia. Our findings suggest that ‘socializing’ intermediation theory to more accurately explain and predict structural outcomes across more diverse contexts requires three key modifications: (1) the attenuation of opportunism, which creates an internalizing social force; (2) the accommodation of non‐monetary objectives, which creates an externalizing social force; and (3) the perception of transaction capabilities as tractable, which serves as a guidepost for reconciling these two opposing social forces.     

The ‘science’ and ‘practice’ of HRM in small firms

This paper looks at the ‘science’ and ‘practice’ of human resource management in small firms. While there is growing evidence that the practice of human resource management in small firms is characterized by informality, there is less evidence about the science, or explaining why this is the case. We look to writing on strategic human resource management, which has at its heart the resource based view of the firm, for possibilities offered to understanding the science of human resource management in small firms.     

Inference by the <Emphasis Type="Italic">m</Emphasis> out of <Emphasis Type="Italic">n</Emphasis> bootstrap in nonparametric frontier models

It is well-known that the naive bootstrap yields inconsistent inference in the context of data envelopment analysis (DEA) or free disposal hull (FDH) estimators in nonparametric frontier models. For inference about efficiency of a single, fixed point, drawing bootstrap pseudo-samples of size m < n provides consistent inference, although coverages are quite sensitive to the choice of subsample size m. We provide a probabilistic framework in which these methods are shown to valid for statistics comprised of functions of DEA or FDH estimators. We examine a simple, data-based rule for selecting m suggested by Politis et al. (Stat Sin 11:1105–1124, 2001), and provide Monte Carlo evidence on the size and power of our tests. Our methods (i) allow for heterogeneity in the inefficiency process, and unlike previous methods, (ii) do not require multivariate kernel smoothing, and (iii) avoid the need for solutions of intermediate linear programs.     

The ‘Urban Age’ in Question

Foreboding declarations about contemporary urban trends pervade early twenty‐first century academic, political and journalistic discourse. Among the most widely recited is the claim that we now live in an ‘urban age’ because, for the first time in human history, more than half the world's population today purportedly lives within cities. Across otherwise diverse discursive, ideological and locational contexts, the urban age thesis has become a form of doxic common sense around which questions regarding the contemporary global urban condition are framed. This article argues that, despite its long history and its increasingly widespread influence, the urban age thesis is a flawed basis on which to conceptualize world urbanization patterns: it is empirically untenable (a statistical artifact) and theoretically incoherent (a chaotic conception). This critique is framed against the background of postwar attempts to measure the world's urban population, the main methodological and theoretical conundrums of which remain fundamentally unresolved in early twenty‐first century urban age discourse. The article concludes by outlining a series of methodological perspectives for an alternative understanding of the contemporary global urban condition.

The <Emphasis Type="Italic">focus groups</Emphasis> in social research: advantages and disadvantages

The focus group (FG) technique has been recently rediscovered by social scientists. It has become the subject of important methodological discussions and it is now considered a very innovative research method. However, such a widespread use of FG seems to have become a fashionable research technique. The impression is that FG is often adopted without any prior consideration of whether it really is the most suitable research technique for achieving the cognitive goals of the research. At the same time, it seems that the FG is often adopted only because it is considered an easy-to-organise and inexpensive technique. The goal of this paper is to evaluate the nature of the FG, analyse its advantages and disadvantages and identify the cognitive problems that it helps to face. In order to discuss these two points, I will focus on the two main characteristics that differentiate the FG from other techniques of information gathering in social research. Firstly, in FGs the informative source is a group. Secondly, the heuristic value of this technique lies in the kind of interaction that emerges during the debate. Several researchers have indicated these two aspects as the main characteristics of FG; but only few authors have translated these comments into serious epistemological and methodological knowledge, thus allowing the FG to give its best results.     

The Network‐Performance Relationship in Knowledge‐Intensive Contexts—A Meta‐Analysis and Cross‐Level Comparison

This study examines the generalizability of the network‐performance relationship across individual and group levels, focusing on knowledge‐intensive contexts. Drawing on a meta‐analytical approach, we synthesize the results of 102 empirical studies to test whether network characteristics such as centrality, brokerage, and tie strength similarly influence the job performance of individuals and groups. Results show that while there are no differences in the direction of the network‐performance relationship across levels, there are substantial differences in magnitude. Individual performance profits more strongly from a high number of direct connections, whereas groups reap higher benefits from brokerage positions. Additional analyses reveal that the network measurement method, tie content, and performance criteria function as moderators of the network performance relationship, but their influence is consistent neither across network characteristics nor across levels. By meta‐analytically comparing and contrasting the network‐performance relationship for individuals and groups, we contribute to multilevel research on networks and organizations. Particularly, we move toward the development of a multilevel homology theory of networks. Implications for theory, practice, and future research are discussed. © 2017 Wiley Periodicals, Inc.     

About “strategy” and “strategies” in supply management

This article addresses the context and content of a generic supply strategy and discusses its strategy-making process. Building mostly on fundamental strategic management theories, the authors explain the role of supply strategy in its managerial context. In so doing, some light is shed on the meaning and use of the terms “strategy” and “strategies”. Also, a practical conceptual framework for supply strategy formulation is provided. The generic checklist, built by segmenting supply management decisions, is intended to guide supply professionals in addressing strategic issues to create value to customers, avoiding confusion and optimising resource allocation.

Adjusting for Non‐Response in Population‐Based Case‐Control Studies

In this paper we discuss the analysis of data from population‐based case‐control studies when there is appreciable non‐response. We develop a class of estimating equations that are relatively easy to implement. For some important special cases, we also provide efficient semi‐parametric maximum‐likelihood methods. We compare the methods in a simulation study based on data from the Women's Cardiovascular Health Study discussed in Arbogast et al. (Estimating incidence rates from population‐based case‐control studies in the presence of non‐respondents, Biometrical Journal 44, 227–239, 2002).     

Evidence‐Based Scope for Reducing “Fire‐Fighting” in Project Management

This paper reviews the problems of project management as reported by 1,879 individuals employed in the construction, manufacturing, process, and service industries in North‐West Europe over 23 years. Data obtained by a written questionnaire confirms that organizational relationships need the most attention. The data exhibits no trends over the 23 years. It indicates that many of the problems of project management are “institutional”; in other words, they are due to organizational cultures rather than inherent in project work. The evidence supports the view that poor discipline at the front‐end of projects results in too much “fire‐fighting” in project execution to overcome problems that could have been prevented. Prevention of these institutional problems requires action at the level of corporate governance, above the level of project management.     

<Emphasis Type="Italic">Notes and Comments:</Emphasis> Profitability in a multiple strategy market

The link between martingales and arbitrage is well-known in financial theory: arbitrage is not available if and only if there exists an equivalent measure such that the discounted prices are martingales with respect to this measure (MME). As a consequence, under MME, any previsible (non-anticipative) strategy cannot have secure (without risk) profit. Moreover, a careful reading of a bootstrap proof of the first fundamental theorem of asset pricing (see Schachermeier (1992)) underlines the fact that, if there is no possibility of arbitrage during any unit interval, then no arbitrage is allowed with any finite temporal horizon strategy.

‘Green’ value chain practices in the furniture industry

This paper draws on the results of interviews with five environmental managers in the furniture industry to develop a taxonomy of environmentally-friendly (‘green’) best practices within the operations management value chain. This taxonomy is then extended to develop a group of propositions concerning the role of management in promoting environmentally-friendly practices. The results suggest that in order to be successful, environmental management strategies must be integrated into all stages of the value chain, which includes all of the processes spanning product design, procurement, manufacturing and assembly, packaging, logistics, and distribution. While the potential for environmental performance improvement in all five of the companies is evident, all of them demonstrated ‘pockets’ of environmentally-friendly practices (EFP) in different areas of their respective value chain functions. The propositions and results emerging from the analysis also suggests that reacting to regulations is no longer sufficient. World-class EFP must anticipate and pre-empt changing environmental regulations and customer expectations, and proactively prepare products, processes and infrastructure for these changes without sacrificing competitive advantage.
