Community leadership cycles and the consolidation of neighbourhood coalitions in the new local governance

The success of the new patterns of local governance depends on engaging communities in a range of partnerships at various geographic scales and administrative levels. In practice, this usually falls to a handful of community leaders in any given locality. Our research on area regeneration partnerships in the UK reveals a community leadership cycle, which proceeds through five phases. The first phase consists of the emergence of a first generation of leaders early on in a partnership, in the second phase their position in the partnership is consolidated and loyalty to the partnership developed, followed by a third phase of the cultivation of a second generation of leaders. Then comes a fourth phase in which the new generation of leaders raise their voices to challenge the established patterns of representation in the partnership. In the final phase, individual leaders exit from the partnership. This community leadership cycle is part of building multi-sector leadership coalitions in the neighbourhoods through strategies combining loyalty, voice and exit.     

Emerging managerial competencies of professionals in the Tanzanian construction industry

The managerial competencies required by professionals in the construction industry in Tanzania to operate effectively in a business environment which is changing as a result of a transition from a socialist to a free-enterprise economy, economic liberalization, globalization and regionalization are explored through a qualitative study. The study reveals that local Tanzanian construction firms are finding it difficult to compete with foreign companies for projects. This is mainly because Tanzanian professionals lack the competencies required to compete and manage projects in a liberalized market economy.

The study thus highlights the need for Tanzanian construction professionals to acquire a better grasp of both occupational and organizational competencies. In this respect, it is suggested that they need post-experience training in order to acquire the competencies required to function successfully in a commercial environment.     

Stochastic labelling of biological images

Many hypotheses made by experimental researchers can be formulated as a stochastic labelling of a given image. Some stochastic labelling methods for random closed sets are proposed in this paper. Molchanov (I. Molchanov, 1984, Theor. Probability and Math. Statist. 29 , 113–119) provided the probabilistic background for this problem. However, there is a lack of specific labelling models. Ayala and Simó (G. Ayala and A. Simó, 1995, Advances in Applied Probability 27 , 293–305) proposed a method in which, given the whole set of connected components, every component is classified in a certain phase or category in a completely random way. Alternative methods are necessary in case the random labelling hypothesis is not reliable. A different kind of labelling method is proposed that considers the environment: the type of every connected component is a function of its location.
Two different biphase images are studied: a cross section of a nerve from a rat, and a cross section of an optic nerve from a lizard.     

Probabilistic Models for Bacterial Taxonomy

We give a survey of different partitioning methods that have been applied to bacterial taxonomy. We introduce a theoretical framework, which makes it possible to treat the various models in a unified way. The key concepts of our approach are prediction and storing of microbiological information in a Bayesian forecasting setting. We show that there is a close connection between classification and probabilistic identification and that, in fact, our approach ties these two concepts together in a coherent way.     

A financial accelerator in the business sector of a macroeconometric model of a small open economy

We have incorporated a financial accelerator mechanism operating through investments in the business sector in a dynamic macroeconometric model of the Norwegian economy. In this new and amended model aggregated credit and equity prices are determined simultaneously in a system characterized by a two-directional contemporaneous causal link, which has been designed and estimated by a new procedure for simultaneous structural model design. Combined with a mechanism where credit and asset prices are mutually influenced by real investments, this creates a financial accelerator amplified by a credit-asset price spiral. Simulations illustrate how the introduction of a financial accelerator significantly reinforces and extends the economic cycles in projections and forecasts, in particular when confronted by a severe shock. Furthermore, monetary policy has a markedly stronger effect in the short and medium term, while the impact of fiscal policy is affected to a relatively small degree as it is more remotely linked to financial markets.     

Multinationals and human resource practices in Ireland: a rejection of the 'new conformance thesis': a reply

This paper reports on a study of 398 people employed in two UK service organizations: a hospital and two divisions of a high street bank. The main purpose of the study was to determine the degree to which dispositional factors (predisposition to trust and trait anxiety) and situational factors (seven aspects of the job environment) predicted a person's reported trust in their managers. Two types of managers were investigated: a person's immediate line manager and ‘senior managers in their industry’. It was hypothesized that the dispositional factors would have a greater influence on trust in managers in the industry and that situational factors would have a greater influence on trust in one's immediate line manager. The first hypothesis was supported, but the second was not. It was found that trust in both types of managers was best predicted by a combination of general disposition to trust (not trait anxiety) and situational factors: five of the seven situational factors had a role in predicting intention to trust. This reflects the complexity involved in predicting trust at work and the managerial challenge of creating a trusting culture.

An Investigation of Justice in supply chain relationships and their performance impact

Justice is important in improving performance of supply chain relationships. However, the role of justice in improving performance in supply chain relationships is an under-investigated subject in the literature. In studying the joint impact of justice dimensions, the traditional assumption is that the three forms of justice interact with each other in a multiplicative manner. However, this assumption creates a managerial problem as discussed in this paper. We outline a different view of how the justice dimensions interact with one another utilizing the constraining factor model (CFM). We show that the CFM resolves some of the problems arising from the choice of multiplicative interaction of justice measures on performance. Specifically, we demonstrate that an increase in procedural, distributive or interactional justice results in a significant and positive improvement in performance only if the specific justice dimension is the constraining factor in the relationship. Overall, our analysis suggests that all three dimensions are important and a high level of one of the justice elements will not compensate for a low level of another, a view that is put forward by a number of past research studies in justice. We discuss the theoretical and managerial implications of our findings.     

On startups and doublethink – resistance and conformity in negotiating the meaning of entrepreneurship

Startup entrepreneurship is – in the literature, in the discourse of those engaging in it, and in cultural representations of the same – presented both as resistance against prevailing corporate logics and as a path towards becoming a corporate entity. Resistance, claimed or otherwise, is not just a reaction to a perceived outrage or a power imbalance, but is in itself a constitutive part of contemporary entrepreneurship, particularly as this is culturally constructed. We study this paradox, where a discourse of resistance becomes a productive part of entrepreneurial culture, by way of a case study of a successful startup. We analyze the manner in which people working in the startup utilize ‘doublethink’ to portray the organization both as resistance to an assumed, more corporate, ‘Other’ and also as a budding corporation unto itself. By doing so, we highlight how a discourse of resistance works as a value in entrepreneurship culture as well as a productive element of the same. In our case, resistance and corporate conformity come together in a way that defies easy classification; one where notions of resistance exist as easy-to-adopt identity positions and where doublethink becomes a productive way of dealing with corporate success.     

Casinos,casino size,and crime: A panel data analysis of Michigan counties

Growth in legal gaming in the United States over the past quarter century or so is well-documented. One important factor fueling this growth was the passage of the Indian Gaming Regulatory Act of 1988, which permitted Native American tribes to establish, under agreements or “compacts” with the states in which they are located, casinos offering what is known as Class III gaming: slot machines, blackjack, roulette, and other games. Since the passage of the Act, there have been 21 Native American casinos established in Michigan. Also, three non-Native American casinos opened in Detroit in 1999 and 2000. This growth in the number of casinos has sparked a wide-ranging debate over the social and economic impacts of casino development.The purpose of this research is to focus on the crime issue in the broader casino debate. We investigate the impact of these Michigan casinos on the rates of burglary, robbery, larceny and motor vehicle theft (property crimes) in casino host counties as well as in nearby counties. We employ a panel data set with annual observations on all 83 Michigan counties for the period 1994–2010. The dataset includes crime rates taken from the FBI crime data series, variables for the presence of a casino in a county or in a nearby county, the scale of a casino's operations as measured by revenues, and a variety of control variables suggested by the broader literature investigating the factors that determine crime rates generally.Our results suggest that in most cases the property crime rates studied are not affected by the presence or size of a casino in a county or in a nearby county. The largest such impact, which is negative, is for motor vehicle theft. The size of a casino does have a small positive effect on the motor vehicle theft rate.
