Supporting group work in Scottish primary classrooms:Improving the quality of collaborative dialogue

A large body of research has demonstrated the value of fostering peer interaction in the context of collaborative group work as an effective strategy to facilitate learning. The present study attempted to enable teachers in a varied sample of 24 Scottish primary classrooms to improve the quality of collaborative group work interaction among their pupils. Observations were carried out at three time points during the year of the intervention, both during whole class teaching and planned group work activity. A global rating instrument was also used to evaluate the overall quality of classroom environment created by participating class teachers to support group work sessions. The results showed significant increases both in the observed frequencies of children's collaborative dialogue and in the rated quality of classroom learning environments over the course of the study. The implications of these results are discussed in the context of current curricular reform.

The executive committee of the Greek Professional Association of Social Work in an age of austerity: examining its response

This paper explores the response by the Greek Association of Social Workers (SKLE) to Greece's current economic crisis. Socioeconomic conditions in Greece have deteriorated rapidly since the imposition of a Structural Adjustment Programme as a condition of the loan Troika provided to Greece to address its class-based public debt crisis. Interviews were conducted with SKLE Executive Committee members to examine SKLE's response in the context of newly raised inequalities. Research results show that SKLE recognised the negative consequences to both service users and its members. However, SKLE continues to reformulate its strategy mostly as a social partner. SKLE's previous strategy entailed amongst other things the analysis of policy proposals and participation in welfare related government committees. This strategy is no longer relevant because decision-making powers have been transferred to transnational bodies. This paper elaborates on these findings and discusses the barriers that prohibit SKLE from differentiation of its strategy. Although the research is country specific, it has implications for the broader global debate because professional associations must reformulate their strategies for better serving of both their constituents and the collective good based on the social justice mandate of the profession.

Theorizing temporary spatial clusters and institutional boundary-work in industrial markets

To better understand the nature of temporary spatial clusters (TSC’s) in industrial marketing settings, this conceptual paper first provides a theoretical synthesis of spatial understanding from the industrial marketing (IM) and economic geography (EG) fields, focusing particularly on Doreen Massey’s work on relational space. This leads to a conceptual schema for organizing the IM literature in terms of spatiality, and which also helps clarify the ontological nature of TSCs. We then move to introduce the notion of institutional boundary-work, drawing on the work of Thomas Gieryn, and Andrea Brighenti’s examination of territorology, to conceptualize the activities of market actors engaged in the ongoing social accomplishment of TSCs. Such activities, we suggest, involve these actors ‘marching’ boundaries to assume network influence and maintain market order in IM settings. In summary, therefore, our paper addresses two fundamental questions: i) How do we conceptualize the form of TSCs in IM settings? And, ii) what function(s) are TSCs performing (and how is this being undertaken) in IM? The paper closes by providing methodological guidance for how a research agenda on TSCs within IM activity might be developed, followed by a summary of the managerial implications that emerge from our theorizations.

Measuring work and heat in ultracold quantum gases

We propose a feasible experimental scheme to direct measure heat and work in cold atomic setups. The method is based on a recent proposal which shows that work is a positive operator valued measure (POVM). In the present contribution, we demonstrate that the interaction between the atoms and the light polarization of a probe laser allows us to implement such POVM. In this way the work done on or extracted from the atoms after a given process is encoded in the light quadrature that can be measured with a standard homodyne detection. The protocol allows one to verify fluctuation theorems and study properties of the non-unitary dynamics of a given thermodynamic process.

Mental Health Social Work and the Troubles in Northern Ireland: A Study of Practitioner Experiences

• Summary: During the last decade increasing attention has been paid to the impact of the Troubles1 on social work in Northern Ireland. In this paper, the authors describe the first survey used to test some of the assumptions which exist in the literature. An 87-item questionnaire was applied to a range of social work staff currently working in, or associated with, mental health settings. One hundred and one questionnaires were returned: it is estimated that this represented over 70 per cent of mental health social workers in Northern Ireland. • Findings: The design of the questionnaire elicited both qualitative and quantitative data. The findings reveal a workforce with complex religious and national identities and many of the respondents have experienced relatively high levels of Troubles-related incidents whilst carrying out their duties in a variety of organizational and geographical settings. High proportions of respondents received minimal agency support and training to equip them to deal with Troubles-related problems faced by them during this period. • Applications: The authors conclude that the profession and employing agencies should pay greater attention to past and present effects of the Troubles on social work practice and develop appropriate strategies for supporting, training and resourcing staff in this neglected area.

Child Protection Work and Family Support Practice in Five Family Centres

Academic interest in the work of family centres in the United Kingdom has largely been concerned with categorising the work of such centres in terms of issues of childcare ideology, working practices and degree of service user control. Meanwhile, the re-focusing of child protection services in order to develop child welfare services has largely dominated childcare social work in recent years, with scant attention paid to the role of family centres in relation to this debate. This study is concerned with examining the perspectives of staff and service users in five 'client focussed' family centres in Northern Ireland in relation to how child protection issues are understood and dealt with. It was found that staff enter into negotiations with both referrers and service users to conceptually reframe child protection work as family support practice. This leads to the development of partnership relationships between staff and service users based upon mutual high regard. The work of such centres leaves them well placed to provide integrated services to children in need in line with current government priorities, but could leave some children vulnerable where child protection issues are not amenable to conceptual reframing along family support lines.

Lean software process

This paper shows how the concepts of lean manufacturing can be successfully applied to software development. The key lean concept is to have a minimum of work in progress, which forces problems into the open. The time is then taken to fix the production system so the errors will not occur again.

Experimental Investigation of Stretch Blow Molding, Part 2: Analysis of Process Variables, Blowing Kinematics, and Bottle Properties

The work presented in this paper takes advantage of newly developed instrumentation suitable for in process monitoring of an industrial stretch blow molding machine. The instrumentation provides blowing pressure and stretch rod force histories along with the kinematics of polymer contact with the mould wall. A Design of Experiments pattern was used to qualitatively relate machine inputs with these process parameters and the thickness distribution of stretch blow molded PET (polyethylene terephtalate) bottles. Material slippage at the mold wall and thickness distribution is also discussed in relation to machine inputs. The key process indicators defined have great potential for use in a closed loop process control system and for validation of process simulations.

Domain Wall Propagation in Meso and Nanoscale Ferroelectrics

As part of an ongoing programme to evaluate the extent to which external morphology alters domain wall mobility in ferroelectrics, the electrical switching characteristics of single-crystal BaTiO3 nanorods and thin film plates have been measured and compared. It was found that ferroelectric nanorods were more readily switched than thin plates; increasing the shape constraint therefore appears to enhance switchability. This observation is broadly consistent with previous work, in which local notches patterned along the length of nanorods enhanced switching (McMillen et al 2010 Appl. Phys. Lett. 96 042904), while antinotches had the opposite effect (McQuaid et al 2010 Nano Lett. 10 3566). In this prior work, local enhancement and denudation of the electric field was expected at the notch and antinotch sites, respectively, and this was thought to be the reason for the differences in switching behaviour observed. However, for the simple nanorods and plates investigated here, no differences in the electric field distributions are expected. To rationalise the functional measurements, domain development during switching was imaged directly by piezoresponse force microscopy. A two-stage process was identified, in which narrow needle-like reverse domains initially form across the entire interelectrode gap and then subsequently coarsen through domain wall propagation perpendicular to the applied electric field. To be consistent with the electrical switching data, we suggest that the initial formation of needle domains occurs more readily in the nanorods than in the plates.
