Compulsory income management: Combatting or compounding the underlying causes of homelessness?

Compulsory Income Management (CIM) is a form of conditional welfare that involves the mandatory quarantining of a portion of welfare recipients’ social security payments. Quarantined funds are accessible via a government-issued debit card, with restrictions surrounding where and on what funds can be spent. Official justifications of CIM have framed these policies as attempts to combat substance abuse and gambling problems, and to thus secure better outcomes for welfare recipients and their families. Central to this narrative has been the argument that welfare quarantining will ensure more money is spent on ‘essentials’, including accommodation. No existing studies, however, have specifically interrogated the impacts of CIM on housing security. This article responds to this gap in the literature by reviewing existing research concerning CIM's impacts and locating this research within broader debates regarding the causes of homelessness and the efficacy of individualised policy interventions. In doing so, it highlights CIM's potential to exacerbate housing insecurity not only through technical issues such as rental transfer failures, but also by contributing to underlying stressors such as economic disadvantage; relationship difficulties, poor health and addiction; and social stigma. The article concludes that – far from addressing the structural causes of homelessness – CIM has enflamed them.     

Looking into the ‘black box’ – unlocking the effect of integration on acquisition performance

Extending research on the performance of Mergers and Acquisitions (M&As), this paper seeks to explain how the post-acquisition integration phase affects acquisition performance. Despite extensive research efforts, there remains a scant understanding of how acquisition implementation, particularly in the post-acquisition integration phase, impacts the performance of M&As. Based on an extensive study of eight acquisitions, in this paper, a grounded model detailing the mechanisms by which the post-acquisition integration phase affects acquisition performance is developed. The model posits that integration-related factors do not bear directly upon acquisition performance. Instead, their effect is mediated by functional organizations in both firms. When focusing into these functional mediating dynamics, we observe that integration-related processual, behavioral and cultural factors affect the identified functional mediators in different ways. Going forward, we echo calls for integrated perspectives to the study of M&A and M&A performance in particular.     

Dependence and uncertainty in broker strategies of research intermediaries

This study examines how a research intermediary can successfully manage collaboration among research partners, while mitigating resource dependence in multi-partner programs. For that purpose, two fundamentally different strategies are explored: tertius gaudens and tertius iungens. Previous literature has not addressed the possibility that the effective deployment of tertius broker strategies may be contingent on multiple factors. Using a qualitative in-depth case study, we contribute to the literature by showing that the effective development of the tertius broker strategies in our study context is contingent on partner type, business integration and product readiness.     

Reinforced structural holes

Holes in social structure are variably reinforced by the social organization around the hole. The more reinforced the hole, the greater the difficulty in bridging it, but the more likely a successful bridge will carry information novel, and so potentially valuable, to people on the other side. To study how reinforcement varies with access to structural holes, and the achievement associated with access, I propose a measure of access to reinforced structural holes (RSH), and present results predicting achievement in an integrated banker organization and a balkanized supply-chain organization. In both study populations, the people who have access to structural holes also have access to reinforced structural holes, and all measures of access have a statistically significant association with achievement. However, there is no consistent prediction advantage from incorporating reinforcement in measures of access to structural holes. The reinforced-holes measure predicts compensation better or as well as network constraint and betweenness, but is weaker or no better than a count of nonredundant contacts. I do not infer from the results a rank-order of alternative measures so much as substitutability. I expect achievement to be associated with access to structural holes, but I expect the association to vary across alternative measures depending on how achievement is achieved in a specific population.     

Restaurant Revenue Management at Chevys: Determining the Best Table Mix

Revenue management has been used in a variety of industries and generally takes the form of managing demand by manipulating length of customer usage and price. Supply mix is rarely considered, although it can have considerable impact on revenue. In this research, we focused on developing an optimal supply mix, specifically on determining the supply mix that would maximize revenue. We used data from a Chevys restaurant, part of a large chain of Mexican restaurants, in conjunction with a simulation model to evaluate and enumerate all possible supply (table) mixes. Compared to the restaurant's existing table mix, the optimal mix is capable of handling a 30% increase in customer volume without increasing waiting times beyond their original levels. While our study was in a restaurant context, the results of this research are applicable to other service businesses.     

Acquisition of Telecommunications Bandwidth Under Economies of Scale in Size and Duration of Contracts*

Significant advances in information technology have brought about increased demand for bandwidth. Buyers of bandwidth often encounter bandwidth prices that are decreasing over time. Additionally, bandwidth prices at any point in time are decreasing in total bandwidth purchased and length of contracts. Therefore, buyers face complex decisions in terms of the number of contracts to buy, their bandwidth, and their lengths. In this article, we formulate models for the acquisition of bandwidth from a buyer's perspective. We begin with a model that allows varying contract durations under deterministic demand and without allowing shortages or overlapping contracts. We then formulate a simpler model, which restricts contract lengths over the planning horizon to be equal. We also solve the problem under probabilistic demand and allowing for shortages, which are satisfied by buying additional bandwidth at a premium. We perform numerical sensitivity analysis to compare the results of the models and illustrate the results with numerical examples. The numerical analyses illustrate that using relatively simple equal‐length contracts produces approximately the same results as the more complicated unequal‐length contract strategy.

Time management as a moderator of relations between stressors and employee strain

The purpose of this study was to examine whether time management behaviours moderated relations between stressors (role conflict, role overload, work-family conflict, and family-work conflict) and strain, as measured by scores on the General Health Questionnaire. It was predicted that use of time management behaviours would be negatively associated with strain. These relations, however, were expected to be mediated by feelings of control over time. It was further predicted that the use of time management behaviours would attenuate stressor-strain relations. Data collected from 525 employed men and women indicated, as predicted, that use of time management behaviours was negatively associated with strain. These relations were partially mediated by feelings of control over time. Moderator tests failed to provide support for time management behaviour as a moderator of stressor-strain relations. Implications of findings are discussed and future directions for time management research are suggested.     

A PLAGUE ON THE PANOPTICON: Surveillance and power in the global information economy

With technological advances in data-manipulation, the increased 'informability' of our daily lives and the potential for social management, surveillance has become a key site for understanding the workings of power within the global informational economy. Jeremy Bentham's Panopticon has, courtesy of Foucault, become a dominant metaphor in surveillance studies. This central eye, aimed at the moral reform of institutionalized bodies and operating through a de facto closure of individual agency, tends to limit our conception of the complex ways surveillance serves and disrupts power. Through analysis of commercial and workplace surveillance, this paper shows that power is contested and agency never completely closed down. To comprehend this negotiated relationship, an alternative framework - 'plague management' - is presented. This envisions surveillance within a social setting operated by multiple agents who themselves are open to the gaze of those surveyed. The aim of this project is to categorize rather than to reform and cure, and moreover space is available for resistance. On the global scale, new technologies have opened up space for informal, local surveillances to be effectively linked to media and Internet audiences. These 'surveillance networks', informal alliances of a variety of actors, have the potential to radically alter orthodox relations of power by evading the information controls of the state and connecting a local gaze with the global community. This paper concludes that although surveillance studies has rightly been concerned with the control capacities of IT, a balance must be actively sought with the facilitative, enabling and even democratic impulses nascent in the new technology.     

Economic Production Lot Sizing with Periodic Costs and Overtime*

Traditional approaches for modeling economic production lot‐sizing problems assume that a single, fixed equipment setup cost is incurred each time a product is run, regardless of the quantity manufactured. This permits multiple days of production from one production setup. In this paper, we extend the model to consider additional fixed charges, such as cleanup or inspection costs, that are associated with each time period's production. This manufacturing cost structure is common in the food, chemical, and pharmaceutical industries, where process equipment must be sanitized between item changeovers and at the end of each day's production. We propose two mathematical problem formulations and optimization algorithms. The models' unique features include regular time production constraints, a fixed charge for each time period's production, and the availability of overtime production capacity. Experimental results indicate the conditions under which our algorithms' performance is superior to traditional approaches. We also test the procedures on a set of lot‐sizing problems facing a national food processor and document their potential economic benefit.
