I ask whether the highly confrontational collective bargaining in the airlines is unique to that industry or a sign of a deepening
crisis in union–management relations nationally. First, airline labor relations are reviewed in the context of extremely contentious
negotiations, intense industry competition, complex and fragmented bargaining structures, frequent bankruptcies, and unpredictable
external shocks. Next, concessionary bargaining in the airlines is discussed, and a new and extreme form of concessionary
bargaining is identified. The emergence of the new concessionary bargaining in the airlines and its spread to the automobile
sector is then interpreted as the early signs of a fundamental transformation of collective bargaining. The implications of
the new concessionary bargaining are then described at the workplace, company, union, and societal levels.
A laboratory experiment examined the effects of applying decision support system (DSS) technology to decision making in ill-structured problem environments under varying information conditions. Marketing executives participated in the experiment which investigated the effects of DSS availability, DSS training, and data availability on dependent variables that included: (1) the number of alternatives considered by a subject during decision making, (2) the period of time spent by a subject to complete the decision-making process, (3) the subject's perceived confidence in the decisions he or she had made, (4) the amount of data considered by a subject's during decision making, (5) the individual subject's decision processing, and (6) the subject's performance overall. Our results indicate that all three factors significantly affect the number of alternatives considered by subjects during the decision-making process. We therefore suggest that DSS training be coordinated with decision training in order to realize the potential of DSSs as described in the DSS literature. 相似文献
The implications of constrained dependent and independent variables for model parameters are examined. In the context of linear model systems, it is shown that polyhedral constraints on the dependent variables will hold over the domain of the independent variables when a set of polyhedral constraints is satisfied by the model parameters. This result may be used in parameter estimation, in which case all predicted values of the dependent variables are consistent with constraints on the actual values. Also, the implicit constraints that define the set of parameters for many commonly used linear stochastic models with an error term yield values of the dependent variables consistent with the explicit constraints. Models possessing these properties are termed “logically consistent”. 相似文献
Sociologists have examined how structural economic change affects household social organization and generation of household income from different sources. The introduction of elements of a market economy into rural Russia in the early 1990s provides a unique opportunity to examine these relationships. Much of the work on this topic, however, has been conducted in black earth zone, agriculturally dependent regions. Less attention has been given to non‐black‐earth zone, forest resource dependent regions. This article addresses this limitation by comparing the relationships between household income generation strategies and household social organization in a 2009 survey of villages in three forest resource dependent regions in northwest Russia with findings from a 2006 survey of households in nine agricultural regions of Russia. Income generated from enterprises based on household social organization—household labor and social helping networks—is substantially greater in agriculturally dependent than in forest resource dependent regions. We discuss the implications of these findings for understanding intranational regional differences in the relationship between economic systems, household social organization, and rural household economies as well as the obstacles facing policymakers and environmentalists who attempt to shift household income generation strategies away from an environmentally harmful lumber industry to income generation activities that are less harmful to the environment. 相似文献
Moral panics are central to social work policy and practice. Voluntary agencies and statutory bodies (including governments) create and sustain moral panics in order to raise awareness of, and win support for, their own understandings of social issues and problems. This is not a neutral enterprise; on the contrary, moral panics often have consequences that are negative, whether intended or unintended. Far from leading to greater social justice and a more equal society, they may reinforce stereotypes and lead to fearful, risk-averse practice. This paper discusses one such moral panic in 2013 that centred on the story of ‘Maria’, a Bulgarian Roma child living in Greece. The paper explores the meaning and use of the concept of moral panic before unpacking this case-study example in more detail. We argue that the moral panic over ‘Maria’ has much to tell us about ideas of welfare and protection, institutional racism and children and childhood, as well as the connections between ‘private troubles’ and ‘public issues’. We conclude that social work as a profession must stand up to complexity, and in doing so, be aware of its own role in relation to moral panics. 相似文献
The widely used methods for estimating adult mortality rates from sample survey responses about the survival of siblings, parents, spouses, and others depend crucially on an assumption that, as we demonstrate, does not hold in real data. We show that when this assumption is violated so that the mortality rate varies with sibship size, mortality estimates can be massively biased. By using insights from work on the statistical analysis of selection bias, survey weighting, and extrapolation problems, we propose a new and relatively simple method of recovering the mortality rate with both greatly reduced potential for bias and increased clarity about the source of necessary assumptions. 相似文献
This paper describes a simulation experiment to evaluate the relative effectiveness of rescheduling policies in capacity-constrained, just-in-time (JIT) make-to-stock production environments. Three performance measures were analyzed: average finished goods inventory, total units of sales lost, and a measure of schedule instability. Among the three loading methods we studied (level loading, front loading, and back loading), none was superior across all three performance measures. Level loading was the most robust, while back loading had an interaction effect with forecasting model and capacity level. Time fence scenario was found not to be as significant a factor in system performance as reported by previous research. Once an acceptable time fence scenario is selected, attempts to optimize this factor do not appear to offer significant improvement. It was found that higher demand variation, larger forecast errors, and tight capacity lead to the degradation of system performance. Judicious use of slack capacity helps a system to incorporate the periodic schedule changes typical of JIT systems. 相似文献
Micro-sociological theory has traditionally stressed interactional pressures towards alignment: actors’ attempts to co-construct a shared definition of the situation. We argue that this model provides an insufficient account of the coordination of action and of the emergence of intersubjectivity among actors. To complement the focus on alignment, we develop a theory of disruption—a perceived misalignment of the dramaturgical structure of interaction in coordinating expected lines of action. We develop a theory of the interaction order that takes the interplay between interactional alignment and disruption as a foundational challenge both for sociology and for actors in their everyday lives. We focus on the practical ways in which actors negotiate both interactional breaches and wider relational ruptures, and how they differentiate between disruptions-of relations and disruptions-for them. By doing so, we connect the interaction order to a wider relational order, providing a bridge between micro-level interactionism and the sociology of culture.
This commentary critiques Betthäuser, Bourne and Bukodi's (2020) paper which finds that cognitive ability does not substantially mediate class of origin effects on educational and occupational outcomes. From these results, they conclude that cognitive ability is only of minor importance for social stratification, reasserting their view of the primacy of class origins for social stratification. The central issue surrounding cognitive ability in social stratification is its effects on socioeconomic attainments vis-à-vis socioeconomic origins, not the extent that cognitive ability mediates classorigin effects. Their analytical strategy of estimating the extent that cognitive ability mediates class origineffects is misleading because: it ignores the only moderate associations of socioeconomic origins with educational and occupational outcomes; the stronger direct effects of cognitive ability; the associations of parents’ ability with their own socioeconomic attainments; and the genetic transmission of cognitive ability and other traits relevant to social stratification from parents to their children. 相似文献
This paper examines the wider social impacts of hosting the London 2012 Olympic Games and its 'legacy' ambitions in East London, emphasizing securitization as an inbuilt feature of the urban regeneration project. Drawing on extensive original empirical research, the paper analyses the modalities of Olympic safety and security practices within the Olympic Park itself and their wider impact, while also connecting this research to theorization and debates in urban sociology and criminology. In this complex setting, a raft of formal and informal, often subtle, regulatory mechanisms have emerged, especially as visions of social ordering focused on 'cleansing' and 'purifying' have 'leaked out' from the hyper-securitized 'sterilized' environment of the Olympic Park and become embedded within the Olympic neighbourhood. In such complex circumstances, applying Douglas' (1966) work on purity and danger to the spatial realm provides a key conceptual framework to understand the form and impact of such processes. The imposition of order can be seen to not only perform 'cleansing' functions, but also articulate multiple symbolic, expressive and instrumental roles. 相似文献
