Cittadinanza, lavoro e diritti sociali nella crisi europea = Citizenship, work and social rights in the European crisis. WP C.S.D.L.E. “Massimo D’Antona”.INT – 100/2013

This paper explores the limits and potentials of European citizenship as a transnational form of social integration, taking as comparison Marshall's classical analysis of the historical development of social rights in the context of the national Welfare State. It is submitted that this potential is currently frustrated by the prevailing negative-integration dimension in which the interplay between Union citizenship and national systems of Welfare State takes place. This negative dimension pervades the entire case law of the Court of Justice on Union citizenship, even becoming dominant – after the famous Viking and Laval judgements – in the ways in which the judges in Luxembourg have built, and limited, what in Marshall’s terms might be called the European collective dimension of “industrial citizenship”. The new architecture of the economic and monetary governance of the Union, based as it is on an unprecedented effort towards a creeping constitutionalisation of a neo-liberal politics of austerity and welfare retrenchment, is destined to strengthen the de-structuring pressures on the industrial-relation and social protection systems of the member States. The conclusions sum-up the main critical arguments and make some suggestions for an alternative path for re-politicising the social question in Europe.

Action research in a collective organisation:Developing an education programme in a pressure group

The aim of this project was to develop the education work of an environmental pressure group. The research devised and implemented a project to produce multi-media teaching packs on the urban environment. Whilst this involved understanding environmental education it was necessary to research beyond this to include the various structural and dynamic constraints on change in the field. This presented a number of methodological difficulties; from the resolution of which a model of the research process involved in this project has been developed. It is argued that research oriented towards practical change requires the insights of an experienced practitioner to be combined with the rigours of controlled systematic enquiry. Together these function as a model-building process encompassing intuition, induction and deduction. Model testing is carried out through repeated intervention in the field; thus an interplay between researcher and client ensues such that the project develops in a mutually acceptable direction. In practice, this development will be both unpredictable and erratic. Although the conclusions reached here are based on a single case study they address general methodological issues likely to be encountered in different field settings concerned with different practical problems.

Institutional work at field-configuring events:shaping industry change within sustainable transitions

Adopting an institutional approach from organization studies, this paper explores the role of key actors on “purposeful governance for sustainability” (Smith, Voss et al. 2010: 444) through the case of smart metering in the UK. Institutions are enduring patterns in social life, reflected in identities, routines, rules, shared meanings and social relations, which enable, and constrain, the beliefs and behaviours of individual and collective actors within a field (Thornton and Ocasio 2008). Large-scale external initiatives designed to drive regime-level change prompt ‘institutional entrepreneurs’ to perform ‘institutional work’ – “purposive action aimed at creating, maintaining and disrupting institutions” (Lawrence and Suddaby, 2006). Organization scholars are giving increasing attention to ‘field-configuring events’ (FCEs) which provide social spaces for diverse organizational actors to come together to collectively shape socio-technical pathways (Lampel and Meyer 2008). Our starting point for this exploratory study is that FCEs can offer important insights to the dynamics, politics and governance of sustainability transitions. Methodologically, FCEs allow us to observe and “link field evolution at the macro-level with individual action at the micro-level” (Lampel and Meyer, 2008: 1025). We examine the work of actors during a series of smart metering industry forums over a three-year period (industry presentations [n= 77] and panel discussions [n= 16]). The findings reveal new insights about how institutional change unfolds, alongside technological transitions, in ways that are partial and aligned with the interests of powerful incumbents whose voices are frequently heard at FCEs. The paper offers three contributions. First, the study responds to calls for more research examining FCEs and the role they play in transforming institutional fields. Second, the emergent findings extend research on institutional work by advancing our understanding of a specific site of institutional work, namely a face-to-face inter-organizational arena. Finally, in line with the research agenda for innovation studies and sustainability transitions elaborated by Smith et al (2010), the paper illustrates how actors in a social system respond to, translate, and enact interventions designed to promote industrial transformation, ultimately shaping the sustainability transition pathway.

Organizational learning and emotion:constructing collective meaning in support of strategic themes

Missing in the organizational learning literature is an integrative framework that reflects the emotional as well as the cognitive dynamics involved. Here, we take a step in this direction by focusing in depth over time (five years) on a selected organization which manufactures electronic equipment for the office industry. Drawing on personal construct theory, we define organizational learning as the collective re-construal of meaning in the direction of strategically significant themes. We suggest that emotions arise as members reflect on progress or lack of progress in achieving organizational learning. Our evidence suggests that invalidation - where organizational learning fails to correspond with expectations - gives rise to anxiety and frustration, while validation - where organizational learning is aligned with or exceeds expectations - evokes comfort or excitement. Our work aims to capture the key emotions involved as organizational learning proceeds. © The Author(s) 2012.

Pleasure, pain and procrastination:reflections on the experience of doing memory-work research

The focus of this article is the process of doing memory-work research. We tell the story of our experience of what it was like to use this approach. We were enthused to work collectively on a "discovery" project to explore a method with which we were unfamiliar. We hoped to build working relationships based on mutual respect and the desire to focus on methodology and its place in our psychological understanding. The empirical activities highlighted methodological and experiential challenges, which tested our adherence to the social constructionist premise of Haug's original description of memory work. Combined with practical difficulties of living across Europe, writing and analyzing the memories became contentious. We found ourselves having to address a number of tensions emanating from the work and our approach to it. We discuss some of these tensions alongside examples that illustrate the research process and the ways we negotiated the collective nature of the memory-work approach. © 2012 Copyright Taylor and Francis Group, LLC.

Workplace Discrimination Climate and Team Effectiveness: The Mediating Role of Collective Value Congruence, Team Cohesion, and Collective Affective Commitment

This study explored the relationship between workplace discrimination climate on team effectiveness through three serial mediators: collective value congruence, team cohesion, and collective affective commitment. As more individuals of marginalized groups diversify the workforce and as more organizations move toward team-based work (Cannon-Bowers & Bowers, 2010), it is imperative to understand how employees perceive their organization’s discriminatory climate as well as its effect on teams. An archival dataset consisting of 6,824 respondents was used, resulting in 332 work teams with five or more members in each. The data were collected as part of an employee climate survey administered in 2011 throughout the United States’ Department of Defense. The results revealed that the indirect effect through M1 (collective value congruence) and M2 (team cohesion) best accounted for the relationship between workplace discrimination climate (X) and team effectiveness (Y). Meaning, on average, teams that reported a greater climate for workplace discrimination also reported less collective value congruence with their organization (a1 = -1.07, p < .001). With less shared perceptions of value congruence, there is less team cohesion (d21 = .45, p < .001), and with less team cohesion there is less team effectiveness (b2 = .57, p < .001). In addition, because of theoretical overlap, this study makes the case for studying workplace discrimination under the broader construct of workplace aggression within the I/O psychology literature. Exploratory and confirmatory factor analysis found that workplace discrimination based on five types of marginalized groups: race/ethnicity, gender, religion, age, and disability was best explained by a three-factor model, including: career obstruction based on age and disability bias (CO), verbal aggression based on multiple types of bias (VA), and differential treatment based on racial/ethnic bias (DT). There was initial support to claim that workplace discrimination items covary not only based on type, but also based on form (i.e., nonviolent aggressive behaviors). Therefore, the form of workplace discrimination is just as important as the type when studying climate perceptions and team-level effects. Theoretical and organizational implications are also discussed.

Role of Vinculin in Regulating Force-Sensitive Dynamics of Adherens Junctions During Collective Cell Migration

Dynamic processes such as morphogenesis and tissue patterning require the precise control of many cellular processes, especially cell migration. Historically, these processes are thought to be mediated by genetic and biochemical signaling pathways. However, recent advances have unraveled a previously unappreciated role of mechanical forces in regulating these homeostatic processes in of multicellular systems. In multicellular systems cells adhere to both deformable extracellular matrix (ECM) and other cells, which are sources of applied forces and means of mechanical support. Cells detect and respond to these mechanical signals through a poorly understood process called mechanotransduction, which can have profound effects on processes such as cell migration. These effects are largely mediated by the sub cellular structures that link cells to the ECM, called focal adhesions (FAs), or cells to other cells, termed adherens junctions (AJs).

Overall this thesis is comprised of my work on identifying a novel force dependent function of vinculin, a protein which resides in both FAs and AJs - in dynamic process of collective migration. Using a collective migration assay as a model for collective cell behavior and a fluorescence resonance energy transfer (FRET) based molecular tension sensor for vinculin I demonstrated a spatial gradient of tension across vinculin in the direction of migration. To define this novel force-dependent role of vinculin in collective migration I took advantage of previously established shRNA based vinculin knock down Marin-Darby Canine Kidney (MDCK) epithelial cells.

The first part of my thesis comprises of my work demonstrating the mechanosensitive role of vinculin at AJ’s in collectively migrating cells. Using vinculin knockdown cells and vinculin mutants, which specifically disrupt vinculin’s ability to bind actin (VinI997A) or disrupt its ability to localize to AJs without affecting its localization at FAs (VinY822F), I establish a role of force across vinculin in E-cadherin internalization and clipping. Furthermore by measuring E-cadherin dynamics using fluorescence recovery after bleaching (FRAP) analysis I show that vinculin inhibition affects the turnover of E-cadherin at AJs. Together these data reveal a novel mechanosensitive role of vinculin in E-cadherin internalization and turnover in a migrating cell layer, which is contrary to the previously identified role of vinculin in potentiating E-cadherin junctions in a static monolayer.

For the last part of my thesis I designed a novel tension sensor to probe tension across N-cadherin (NTS). N-cadherin plays a critical role in cardiomyocytes, vascular smooth muscle cells, neurons and neural crest cells. Similar to E-cadherin, N-cadherin is also believed to bear tension and play a role in mechanotransduction pathways. To identify the role of tension across N-cadherin I designed a novel FRET-based molecular tension sensor for N-cadherin. I tested the ability of NTS to sense molecular tension in vascular smooth muscle cells, cardiomyocytes and cancer cells. Finally in collaboration with the Horwitz lab we have been able to show a role of tension across N-cadherin in synaptogenesis of neurons.

The Art of Change Movement: an anti-oppressive Social Work initiative

This article presents the Art of Change Movement (Movimiento Arte del Cambio), which has developed out of a project of the Association of Social Workers Without Boundaries (Asociación Trabajadores/as Sociales Sin Fronteras), with the collaboration of the Faculty of Social Work at Universidad de Granada and of education professionals, incorporating theatrical creativity and musical expression as pedagogical and social intervention tools. The aim is for the initiative to become another instrument in the fight against oppression. Through a laboratory for collective creativity involving students and professionals from social work and other social science disciplines, the movement seeks social transformation through artistic expression, based on political commitment and sustainable development that empowers participants.

Community social innovation: a view of experiences of housing occupation from the Social Work perspective

This work aims to reflect on the concept of social innovation, questioning its explanatory capacity for the discipline of social work. For this purpose, certain on-going debates with regard to this concept are examined and certain minimum dimensions are offered to enable an analysis of the social innovation strategies that certain affected groups implement to meet social needs. The approach is to construct «glasses» that permit an analytical engagement with new realities and with the strategies used by certain social groups to resolve situations of severe vulnerability. Finally, a case study is presented: a strategic group known as the Corrala Utopía that seeks to respond to severe housing problems and is developing in the city of Seville. The article highlights the elements of community social innovation emerging from the experience studied.

“Art Will Not Disappear Into Nothing; It Will Disappear Into Everything“: The Black Audio Film Collective and Latin America

The development of Latin American cinema in the 1960s was underwritten by a number of key texts that outlined the aesthetic and political direction of individual filmmakers and collectives (Solanas and Getino, 1969; Rocha, 1965; Espinosa, 1969). Although asserting the specificity of Latin American culture, the theoretical foundations of its New Wave influenced oppositional filmmaking way beyond its own regional boundaries. This chapter looks at how movements in British art cinema, especially the Black Audio Film Collective, were inspired and propelled by the theories behind New Latin American cinema. Facilitated by English translations in journals such as Jump Cut in the early ‘80s, Cuban and Argentine cinematic manifestoes provided a radical alternative to the traditional language of film theory available to filmmakers in Europe and works such as Signs of Empire (1983-4); Handsworth Songs (1986) and Seven Songs for Malcolm X (1993) grew out of this trans-continental exchange. The Black Audio Film Collective represented a merging of politics, popular culture, and art that was, at once, oppositional and melodic. Fusing postcolonial discourse with pop music, the avant-garde and re-imaginings of subalternity, the work of ‘The Collective’ provides us with a useful example of how British art cinema has drawn from theoretical foundations formed outside of Europe and the West. As this chapter will argue however, the Black Audio Film Collective’s work can also be read as a reaction to the specificity of British socio-politics of the ‘80s and ‘90s. Its engagement with the aesthetico-political strategies of Latin American cinema, then, undercut what was a solidly British project, rooted in (post)colonial history and emerging ideas of disaporic identity. If the propulsive thrust of The Black Audio Film Collective’s art was shaped by Third Cinema, its images and concerns were self-consciously British.

L’inclusion scolaire dans l’enseignement primaire: L’évaluative formative comme source de progression collective?

Ce travail s’inscrit dans le champ des recherches concernant les pratiques inclusives en milieu scolaire ordinaire dans l’enseignement primaire. En France, le système éducatif propose de scolariser les élèves à besoins éducatifs particuliers soit en classe ordinaire, soit en classe spécialisée, bien que les gouvernements valorisent l’accueil en milieu ordinaire depuis la loi de 2005. Or, ceci questionne les pratiques des acteurs de l’école sur la prise en charge de ces élèves. Partant des travaux montrant que les enseignants utilisant l’évaluation formative gèrent mieux la diversité des élèves, nous étudions ici dans quelle mesure cette fonction de l’évaluation aiderait les élèves présentant des besoins éducatifs particuliers à acquérir des connaissances grâce aux feedbacks émis lors d’évaluations orales et de corrections collectives. L’analyse des données recueillies à l’aide d’entretiensavec des enseignants et d’observations d’élèves fait ressortir les attitudes des acteurs, les interactions et les régulations. (DIPF/Orig.)

Evolution of psychosocial factors at work in a French region

International audience

Do teacher stereotypes about school tracks function as expectations at the collective level and do they relate to the perception of obstacles in the classroom and to teachers’ self-efficacy beliefs?

The effects of individual teacher expectations have been the subject of intensive research. Results indicate that teachers use their expectations to adapt their interactions with their students to some degree (as summarized in a review by Jussim & Harber, 2005). This can in turn lead to expectancy-confirming student developments. While there are studies on the Pygmalion effect on individual students, there is only little research on teacher judgements of whole classes and schools. Our study aims to extend the perspective of teacher judgements at the collective level to stereotypes within the context of school tracking. The content and structure of teachers’ school track stereotypes are investigated as well as the question of whether these stereotypical judgements are related to teachers’ perception of obstacles to their teaching and their teaching self-efficacy beliefs. Cross-sectional data on 341 teachers at two different school types from the Panel Study at the Research School „Education and Capabilities“ in North Rhine-Westphalia (PARS) (see Bos et al., 2016) were used for two purposes: First, the structure of teachers’ stereotypes was identified via an exploratory factor analysis. Second, in follow-up regression analyses, the stereotype dimensions extracted were used to predict teachers’ perceptions of obstacles to their classroom work and their individual and collective teacher self-efficacy beliefs. Results showed that – after controlling for the average cognitive abilities and the average cultural capital of the students – teacher stereotypes were indeed related to perceived obstacles concerning their classroom work and their self-efficacy beliefs. After a discussion of the strengths and limitations of the present research, the article closes with a short proposal of a future research framework for collective Pygmalion effects. (DIPF/Orig.)

Guided Migration and Collective Behavior: Cell Dynamics during Cancer Progression

This dissertation focuses on gaining understanding of cell migration and collective behavior through a combination of experiment, analysis, and modeling techniques. Cell migration is a ubiquitous process that plays an important role during embryonic development and wound healing as well as in diseases like cancer, which is a particular focus of this work. As cancer cells become increasingly malignant, they acquire the ability to migrate away from the primary tumor and spread throughout the body to form metastatic tumors. During this process, changes in gene expression and the surrounding tumor environment can lead to changes in cell migration characteristics. In this thesis, I analyze how cells are guided by the texture of their environment and how cells cooperate with their neighbors to move collectively. The emergent properties of collectively moving groups are a particular focus of this work as collective cell dynamics are known to change in diseases such as cancer. The internal machinery for cell migration involves polymerization of the actin cytoskeleton to create protrusions that---in coordination with retraction of the rear of the cell---lead to cell motion. This actin machinery has been previously shown to respond to the topography of the surrounding surface, leading to guided migration of amoeboid cells. Here we show that epithelial cells on nanoscale ridge structures also show changes in the morphology of their cytoskeletons; actin is found to align with the ridge structures. The migration of the cells is also guided preferentially along the ridge length. These ridge structures are on length scales similar to those found in tumor microenvironments and as such provide a system for studying the response of the cells' internal migration machinery to physiologically relevant topographical cues. In addition to sensing surface topography, individual cells can also be influenced by the pushing and pulling of neighboring cells. The emergent properties of collectively migrating cells show interesting dynamics and are relevant for cancer progression, but have been less studied than the motion of individual cells. We use Particle Image Velocimetry (PIV) to extract the motion of a collectively migrating cell sheet from time lapse images. The resulting flow fields allow us to analyze collective behavior over multiple length and time scales. To analyze the connection between individual cell properties and collective migration behavior, we compare experimental flow fields with the migration of simulated cell groups. Our collective migration metrics allow for a quantitative comparison between experimental and simulated results. This comparison shows that tissue-scale decreases in collective behavior can result from changes in individual cell activity without the need to postulate the existence of subpopulations of leader cells or global gradients. In addition to tissue-scale trends in collective behavior, the migration of cell groups includes localized dynamic features such as cell rearrangements. An individual cell may smoothly follow the motion of its neighbors (affine motion) or move in a more individualistic manner (non-affine motion). By decomposing individual motion into both affine and non-affine components, we measure cell rearrangements within a collective sheet. Finally, finite-time Lyapunov exponent (FTLE) values capture the stretching of the flow field and reflect its chaotic character. Applying collective migration analysis techniques to experimental data on both malignant and non-malignant human breast epithelial cells reveals differences in collective behavior that are not found from analyzing migration speeds alone. Non-malignant cells show increased cooperative motion on long time scales whereas malignant cells remain uncooperative as time progresses. Combining multiple analysis techniques also shows that these two cell types differ in their response to a perturbation of cell-cell adhesion through the molecule E-cadherin. Non-malignant MCF10A cells use E-cadherin for short time coordination of collective motion, yet even with decreased E-cadherin expression, the cells remain coordinated over long time scales. In contrast, the migration behavior of malignant and invasive MCF10CA1a cells, which already shows decreased collective dynamics on both time scales, is insensitive to the change in E-cadherin expression.
