Stochastic Modelling of Times to Temperature for Furnaces Supplying Titanium Blooms to a Rolling Mill at TIMET

In conjunction with TIMET at Waunarlwydd (Swansea, UK) a model has been developed that will optimise the scheduling of various blooms to their eight furnaces so as to minimise the time taken to roll these blooms into the finished mill products. This production scheduling model requires reliable data on times taken for the various furnaces that heat the slabs and blooms to reach the temperatures required for rolling. These times to temperature are stochastic in nature and this paper identifies the distributional form for these times using the generalised F distribution as a modelling framework. The times to temperature were found to be similarly distributed over all furnaces. The identified distributional forms were incorporated into the scheduling model to optimise a particular campaign that was run at TIMET Swansea. Amongst other conclusion it was found that, compared to the actual campaign, the model produced a schedule that reduced the makespan by some 35%.     

The contemporary crisis and the social relations department at Harvard: A case study in hegemony and disintegration

The history of sociology is marked by periods of theoretical pluralism and hegemony. Their interplay has resulted in the slow and uneven development of the discipline. Today, however, bodies of theory and practice have become so diverse that many scholars worry that sociology is in a state of disintegration. The theoretical career of Talcott Parsons provides a microcosm in which to explore similar processes. Building on the success of The Structure of Social Action, Parsons led a movement that transformed Harvard's Department of Sociolgy into the Department of Social Relations. There he attempted a grander, but failed synthesis in Toward A General Theory of Action. His case provides a situation in which to explore features of disciplinary integration and fragmentation. The comparison stimulates one to fashion an informed sense of whether sociology is now facing its latest crisis or may be in the process of decomposition as a corpus of study. This research was supported by grants from the American Sociological Association's Fund for the Advancement of the Discipline and by Indiana University Northwest through a sabbatical leave.     

From the 30s to the 60s: The folk music revival in the United States

Conclusion Woody Guthrie's ashes were spread by the wind over the water from a Coney Island, New York pier a few days after he died on Oct. 3, 1967. His wife and children, including his 19-year-old son Arlo, were present as America's greatest folksinger was laid to rest. One of the last things Woody heard before he died was Arlo's recorded voice singing the draft-dodging tale of Alice's restaurant. He must have sensed that the spirit had been passed on. Woody Guthrie died just as the second great wave of popular interest in American folk music was coming to an end. Alice's Restaurant was in many ways one of its last echoes. The symbolism could not have been more poignant. At the center of the first folk revival, Woody Guthrie was a vital source of inspiration for the second.The new generation of singer-songwriters who marked the second wave was largely composed of those with at least some contact with the new mass higher education and those multi-versities that were built to dispense it. They were neither members of a déclassé elite, as could be said of Charles and Pete Seeger and John and Alan Lomax, nor were they authentic folk singers, like Woody Guthrie. Nor could they be. By the 1960s, the conditions that had created the possibility for the first wave of the movement had been irretrievably altered. After the Second World War, with a postwar economic expansion and population explosion under way, America was a different place. Besides, the first folk revival had already claimed authenticity as its own. For the most part, if there was any aspiration toward authenticity amongst the topical singer-songwriters (those in New York City in any case), it was to be as close a copy of the first generation, Guthrie and Seeger, as possible. Purism was the second wave's answer to the authenticity of the first.Being part of an expanding generation of white, college-educated youths affected the form and content of the music that characterized the second wave. The most obvious aspect of this was the arena of performance and the audience who filled it. Gone were the union halls, the singing in working-class bars and beerhalls and at Party functions, all of which had characterized the first wave. These were replaced first by coffee shops and small clubs, either in Greenwich Village or those surrounding college campuses. The forays into the South in support of the civil-rights movement were for the most part short-lived and highly symbolic, not to say self-serving. The real mass audience arrived with the antiwar activity and was largely university centered.It was also this audience that filled the auditoriums and concert halls for the more obviously commercial performances by the singer-songwriters of the second wave. This overlapping public provided the grounds for a new mass market in folk music. Peter, Paul, and Mary, who sang in front of many mass demonstrations in protest against the war in Vietnam or in support of civil rights, were, although they saw themselves as carrying on in the spirit of the Weavers, an entirely commercial creation. In the article from the East Village Other cited above, written just after the first big concert in America against the war in Vietnam, Izzy Young angrily notes that everybody was a part of it except the people managed by Albert Grossman - Peter, Paul and Mary, and Bob Dylan. When the war in Vietnam became popular, three years later, Peter, Paul and Mary flew down to Washington, D.C. to take their place in front of the cameras.Commercial rationality was much more a factor in defining the second folk revival than the first. The possibilities were greater and the structure of the music industry was different. With a new mass market still in the process of formation and thus unspecified in terms of taste, the larger record companies could afford to take a liberal attitude and to include under their label, all the revolutionaries, as Columbia Records proudly announced in its contemporary advertising. Commercial possibilities thus were more important in shaping the musical form and content of second folk revival than politics, which were so central to the first. As opposed to the old left, the new left was a loosely organized contingent of organizations and groups with little coordination between them. In fact, many if not most of the organizations were ad hoc committees formed for a specific strike or demonstration. No one group was thus in a position to exert ideological hegemony. Following from this, at least during the period under discussion, there was little political dogmatism to be found. With no powerful organization to impose it, there was no clear political line to defend and thus to sing about. Even the notion of the people, so central to the first folk revival, was relatively absent in the second. Who were the people addressed? Certainly not the working class or even the common man. I am just a student, Sir, I only want to learn, sang Phil Ochs.During the second folk revival, the people had become the silent majority, the province of the conservative right. Neither in music nor in politics did the new left make many attempts to reach the common man in the street. The people had been massified, according to new left theory, and in the new one-dimensional mass society the grounds of political and social identity were always shifting. Besides, country music had already established itself as the musical genre of the rural, southern, western and white, common man. From a commercial point of view, there was little need to look for authenticity or the people; the market was sufficiently large and getting larger as more and more young people entered the institutions of higher education. Politically, this was not a serious problem either, as long as the aim was not revolution as it had been for the old left. It was sufficient, then, to address the masses of youngsters gathering together at institutions of higher education. If there was a revolution at foot, this was it.While the first wave practically had to invent folk music, the second could draw on the reservoir of public culture that to a large extent resulted from this invention. The networks and institutional support provided by the old left and the personal authority of a figure like Alan Lomax made possible the imposition of rather strict criteria for determining in what exactly folk music consisted. Neither networks nor gatekeepers were so determinate to the second wave. With the folksong and folksinger already invented, the new generation could pick and choose from a rather wide range of options. In addition, by the time the new left and the topical-song movement achieved at least a semblance of cohesion, folk music was already institutionally supported by radical entrepreneurs like Izzy Young and the more commercial recording industry. There were, thus, strong institutional bases for folk music outside of politics. Politics, in other words, was not the only game in town. But neither was commerce. The civil-rights movement and the new social movements that developed out of it opened for a short period a space, a public arena, in which the idea of folk music could be reinvented anew. Within this space the traditions constituted during the first wave of folk revival were experimented with and modified in light of the new social and historical context. America was not the same place in the 1960s as it had been in the 1930s and neither could its folk music be. The actors, the setting, and the songs were all different, yet still the same.In attempting to account for both this continuity and change in the two waves of folk revival we have drawn from both the cognitive approach to the study of social movements, which calls attention to the creative role of social-movement actors in the production of knowledge, and the production of culture perspective, which highlights the effects of institutional arrangements in the production of cultural goods. From the former, we have focused on the changing character of movement intellectuals, those to whom Ralph Rinzler in the epigraph that begins this article gave special place; from the latter, we have noted how, among other things, the changing nature of the recording industry helped recast the folk music revival. We hope that the foregoing has demonstrated that in combining these approaches, as well as areas of research interest, we have uncovered aspects of the folk revival others may have missed.     

Building relational capital: The contribution of episodic and relational community engagement

In this study, we provide evidence of the theorized connection between community engagement and the development of social capital, and the perceived value or worth of relationships among organizations and stakeholders. Using thematic analysis to understand the policy and practice frameworks of community engagement in Australian local government organizations, our analyses reveal two different types of community engagement—relational and episodic—each of which has the potential to contribute to relational dimension of social capital. The study introduces and develops new thinking around the ideas of episodic and relational engagement within the context of community engagement, and their respective contributions to the development of relational capital. Recognizing and identifying episodic and relational community engagement as separate phenomena allows researchers and practitioners to understand the theoretical dimensions of community engagement as a framework for practice.     

Human capital,family structure and religiosity shaping British Muslim women’s labour market participation

Economic activity among Muslim women in the UK remains considerably lower and their unemployment rate significantly higher than among the majority group even after controlling for qualifications and other individual characteristics. This study utilises two data sets to explore possible factors underlying these differences, such as overseas qualifications, language skills and religiosity. It reveals that while religiosity is negatively associated with labour market participation among British Christian-White women, economic activity among Muslim women are not negatively affected by high religiosity. Furthermore, family structure and the presence of dependent children were among the most important factors explaining the latter’s labour market participation, although these relationships were moderated by qualifications. More women with higher qualifications were economically active even if married and with children, although some of them experienced greater unemployment, probably due to discrimination in recruiting practices and choices and preferences on religious grounds.     

Improving Expatriation Success: The Roles of Regulatory Focus and Burnout

The study empirically and theoretically contributes to the human resource management discipline by developing and testing a cohesive model drawing on the pertinent literature from expatriate management, burnout and regulatory focus theory. Drawing on data from 233 expatriate managers, the study aims to examine the relationships between expatriate adjustment and the outcomes of job satisfaction and withdrawal cognitions via expatriate burnout. Specifically, the findings reveal that (a) higher levels of both work adjustment and interaction adjustment lead to reduced expatriate burnout, with the former having a greater effect on burnout than the latter; (b) burnout serves as a full mediator between work adjustment and withdrawal cognitions, and a partial mediator between work adjustment and job satisfaction; and (c) regulatory focus serves to moderate expatriate adjustment–outcome consequences, i.e. promotion‐focused (as opposed to prevention‐focused) expatriates demonstrate a stronger burnout–job satisfaction relationship. Several implications are extracted from the study for regulatory theory, burnout and expatriation management practices as well as suggested avenues for future research.     

Mistreatment and self-reported emotional symptoms: results from the National Elder Mistreatment Study

Many community-residing older adults in the United States report past year mistreatment; however, little is known about mental health correlates of abuse. This study investigated whether a recent history of emotional, physical, or sexual abuse is associated with self-reported emotional symptoms (e.g., anxiety, depression) among a representative sample of older adults. Results demonstrated that each abuse type increased likelihood of reporting emotional symptoms; when other known correlates were controlled, only emotional abuse remained a significant predictor. Additional study of mistreatment-related correlates of depression and anxiety is needed, with a focus on the often overlooked category of emotional mistreatment.     

Peer Victimization,Self‐esteem,and Ego Resilience Types in Adolescents: A Prospective Analysis of Person‐context Interactions

This study examined bidirectional, longitudinal associations between peer victimisation and self‐esteem in adolescents, and tested for moderator effects of undercontrolling, overcontrolling, and ego‐resilient personality types in these associations. Data were used from 774 adolescents ages 11–16 years who participated in a three‐wave (i.e., 2005, 2006, and 2007) longitudinal study. Structural equation modelling analyses in Mplus demonstrated that, controlling for earlier levels of self‐esteem, self‐reported peer victimization was associated with lower self‐esteem across one‐year time intervals. Vice versa, however, low self‐esteem was not predictive of subsequent self‐reported victimization. Evidence was also found for a moderator effect of personality type on the longitudinal associations between self‐esteem and victimization. Only in the subgroup of overcontrolling adolescents was lower self‐esteem related to subsequently higher levels of peer victimization; their undercontrolling and ego‐resilient peers were unaffected.     

The derivation of a brief Student Nurse Stress Index

The lack of an adequate measure of perceived sources of stress for student nurses led to the construction of the Student Nurse Stress Index (SNSI). Responses from 235 first-year student nurses to 35 items from the Beck and Srivastava Stress Inventory (Beck, and Srivastava, 1991), and 15 new items, were subjected to exploratory factor analysis using principal components analysis and oblimin rotation. A reliable 22-variable solution with a simple oblique structure including Academic load, Clinical sources, Interface worries, and Personal problems factors was obtained in this initial sample, and confirmed at an exploratory level in a further independent validation sample of 188 first-year students. Confirmatory factor analysis established the four-factor model in the first sample, but required that three variables load onto more than one factor. This more complex four-factor model was confirmed using independent data from the validation sample, and the total invariance of factor loadings and factor covariances of this more complex four-factor model was established in both data sets simultaneously using multi-sample techniques. The SNSI shows cross-sample factor congruence, good internal reliabilities, and concurrent and discriminant validity across a range of reporting conditions.
