Dup discourses on violence and their impact on the northern ireland peace process

This paper analyses the Democratic Unionist Party's (DUP) discourses about paramilitary violence in Northern Ireland. Drawing on narrative analysis of DUP discourses reported in Northern Ireland's largest unionist newspaper, the News Letter (1998-2006), it explores the relationship between the party's identity, its discourses about republican and loyalist paramilitaries, and the impact of these words on the DUP's electoral success and on the peace process. The paper argues that these discourses may haunt the progress of peace-building, not least because the DUP will find it hard to disentangle itself from a history of scepticism and nay-saying even as it takes a leading role in a devolved Executive designed by an Agreement it longscorned.

Impact of political violence, social trust, and depression on civic participation in Colombia

Civic participation is important for peacebuilding and democratic development; however, the role of mental health has been largely overlooked by policymakers aiming to stimulate engagement in civil society. This study investigated antecedents of civic participation in Colombia, a setting of protracted political conflict, using bootstrapped mediation in path analysis. Past exposure to violence, experience with community antisocial behavior, and perceived social trust were all significantly related to civic participation. In addition, depression mediated the impact of past exposure to political violence and perceived social trust, but not community antisocial behavior, on civic participation. In this context, findings challenged depictions of helpless victims and instead suggested that when facing greater risk (past violence exposure and community antisocial behavior), individuals responded in constructive ways, taking on agency in their communities. Social trust in one’s neighbors and community also facilitated deeper engagement in civic life. Relevant to the mediation test, interventions aiming to increase civic participation should take mental health into account. Limitations and possible future research are discussed.

Identification of lactic acid bacteria strains modulating incretin hormone secretion and gene expression in enteroendocrine cells

Glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) are incretin hormones released from intestinal enteroendocrine (EE) cells and have well-established glucose-lowering actions. Lactic acid bacteria (LAB) colonise the human intestine, but it is unknown whether LAB and EE cells interact. Acute co-culture of LAB with EE cells showed that certain LAB strains elicit GLP-1 and GIP secretion (13-194-fold) and upregulate their gene expression. LAB-induced incretin hormone secretion did not appear to involve nutrient mechanisms, nor was there any evidence of cytolysis. Instead PCR array studies implicated signalling agents of the toll-like receptor system, e.g. adaptor protein MyD88 was decreased 23-fold and cell surface antigen CD14 was increased 17-fold. Mechanistic studies found that blockade of MyD88 triggered significant GLP-1 secretion. Furthermore, blocking of CD14 completely attenuated LAB-induced secretion. A recent clinical trial clearly shows that LAB have potential for alleviating type 2 diabetes, and further characterisation of this bioactivity is warranted.

Promoting Harmonious Relations and Equitable Well-Being: Peace Psychology and “Intractable” Conflicts

The chapter explores Bar-Tal’s legacy in relation to key concepts, perspectives, and findings that comprise the growing field of peace psychology, specifically the promotion of sustainable peace through the indivisible constructs of harmonious relations and equitable wellbeing. Analyzed through a peace psychology lens, Bar-Tal’s work highlights both the barriers to and bridges for achieving sustainable peace. Central concepts from his work, such as fear, insecurity, and an ethos of conflict, demonstrate key obstacles to fostering harmonious intergroup relations based on social justice. Bar-Tal’s work also identifies processes that can overcome these barriers, which is consistent with peace psychology’s emphasis on the development of constructive responses to violence and conflict. For example, the chapter outlines how confidence-building mechanisms, mutually respectful identities, and reconciliation processes, may help foster an ethos of peace that can be embedded in the structure of societies through peace education. The chapter concludes with implications and suggestions for future research, with a focus on the role of young people in settings of prolonged intergroup division and generational approaches to peacebuilding, as conceptualized through a peace psychology lens.

Insulin and insulin-like growth factor signaling increases proliferation and hyperplasia of the ovarian surface epithelium and decreases follicular integrity through upregulation of the PI3-kinase pathway

BACKGROUND: The ovarian surface epithelium responds to cytokines and hormonal cues to initiate proliferation and migration following ovulation. Although insulin and IGF are potent proliferative factors for the ovarian surface epithelium and IGF is required for follicle development, increased insulin and IGF activity are correlated with at least two gynecologic conditions: polycystic ovary syndrome and epithelial ovarian cancer. Although insulin and IGF are often components of in vitro culture media, little is known about the effects that these growth factors may have on the ovarian surface epithelium morphology or how signaling in the ovarian surface may affect follicular health and development.

METHODS: Ovaries from CD1 mice were cultured in alginate hydrogels in the presence or absence of 5 μg/ml insulin or IGF-I, as well as small molecule inhibitors of IR/IGF1R, PI 3-kinase signaling, or MAPK signaling. Tissues were analyzed by immunohistochemistry for expression of cytokeratin 8 to mark the ovarian surface epithelium, Müllerian inhibiting substance to mark secondary follicles, and BrdU incorporation to assess proliferation. Changes in gene expression in the ovarian surface epithelium in response to insulin or IGF-I were analyzed by transcription array. Extracellular matrix organization was evaluated by expression and localization of collagen IV.

RESULTS: Culture of ovarian organoids with insulin or IGF-I resulted in formation of hyperplastic OSE approximately 4-6 cell layers thick with a high rate of proliferation, as well as decreased MIS expression in secondary follicles. Inhibition of the MAPK pathway restored MIS expression reduced by insulin but only partially restored normal OSE growth and morphology. Inhibition of the PI 3-kinase pathway restored MIS expression reduced by IGF-I and restored OSE growth to a single cell layer. Insulin and IGF-I altered organization of collagen IV, which was restored by inhibition of PI 3-kinase signaling.

CONCLUSIONS: While insulin and IGF are often required for propagation of primary cells, these cytokines may act as potent mitogens to disrupt cell growth, resulting in formation of hyperplastic OSE and decreased follicular integrity as measured by MIS expression and collagen deposition. This may be due partly to altered collagen IV deposition and organization in the ovary in response to insulin and IGF signaling mediated by PI 3-kinase.

Seeking the New Normal? Troubled Spaces of Encountering Visible Differences in Warsaw

In times of globalisation and super-mobility, ideas of normality are in turmoil. In different societies in, across and beyond Europe, we face the challenge of undoing specific notions of normality and creating more inclusive societies with an open culture of learning to live with differences. The scope of
the paper is to introduce some findings on encounters with difference and negotiations of social values in relation to a growing visibility of difference after 1989 in Poland, on the background of a critique of normality/normalisation and normalcy.On the basis of interviews conducted inWarsaw, we investigate how normality/normalisation discourses of visible homosexuality and physical disability are incorporated into individual self-reflections and justifications of prejudices (homophobia and disabilism). More specifically we argue that there are moments of ‘cultural transgressions’ present in everyday practices towards ‘visible’sexual and (dis)ability difference.

Civic engagement in a divided society: the role of Queen’s University Belfast in Northern Ireland

The purpose of this paper is to examine the role of a university in a society emerging from decades of political violence and to show ways in which public engagement can help promote democratic practice and contribute to the strengthening of peace. Our understanding of the concept of public engagement follows the UK National Coordinating Centre for Public Engagement definition:

'Public engagement describes the myriad of ways in which the activity and benefits of higher education and research can be shared with the public. Engagement is by definition a two-way process, involving interaction and listening, with the goal of generating mutual benefit .'

The case study is provided by the example of Queen's University Belfast. We will begin by examining some of the history and context of the university, then discuss the political and social context of Northern Ireland, before going on to examine some of the publicly engaged work being carried out by Queen's and consider how this might be taken forward.

Speaking Out Online:The Benefits and Risks of Speaking About Sexual Violence for Young People

Speaking out about sexual violence has been a fundamental part of feminist politics since the 1970s. The practice of narrating experiences of violence, either publicly or to friends and family aims to combat the culture of silence and stigmatisation that surrounds sexual violence while also helping individuals to gain a sense of empowerment and connect with other survivors. However, speaking out also contains inherent risks, especially for young people. Survivors may meet with stigmatising or disbelieving responses, and they may lose control over who knows their story and the way in which it is told and retold.
These risks and benefits are altered, and potentially exacerbated, in an online environment. While social media may increase survivors’ ability to contact and connect with others with similar experiences it also makes it harder to control when and how their story is shared. The disjuncture between online and offline environments may also increase feelings of stigmatisation and isolation.
There is a need to explore the specific risks and benefits of speaking out online given both young people’s extensive use of social media for social interactions and the increasing tendency for support and educational services targeted at young people to make use of social media and online environments. This paper draws on literature and some preliminary research to consider both risks and benefits of speaking out online and to open a conversation about the creation of supportive spaces and mechanisms for young people to speak about sexual violence in online environments.

Gender and Material Culture in Britain since 1600

What does material culture tell us about gendered identities and how does gender reveal the meaning of spaces and things?

If we look at the objects that we own, covet and which surround us in our everyday culture, there is a clear connection between ideas about gender and the material world. This book explores the material culture of the past to shed light on historical experiences and identities. Some essays focus on specific objects, such as an eighteenth-century jug or a twentieth-century powder puff, others on broader material environments, such as the sixteenth-century guild or the interior of a twentieth-century pub, while still others focus on the paraphernalia associated with certain actions, such as letter-writing or maintaining eighteenth-century men's hair.

Written by scholars in a range of history-related disciplines, the essays in this book offer exposés of current research methods and interests. These demonstrate to students how a relationship between material culture and gender is being addressed, while also revealing a variety of intellectual approaches and topics.

Lost in Transition? Emerging forms of residential architecture in Kathmandu

Kathmandu has been the last few cities in the world which retained its medieval urban culture up until twentieth century. Various Hindu and Buddhist religious practices shaped the arrangement of houses, roads and urban spaces giving the city a distinctive physical form, character and a unique oriental nativeness. In recent decades, the urban culture of the city has been changing with the forces of urbanisation and globalisation and the demand for new buildings and spaces. New residential design is increasingly dominated by distinctive patterns of Western suburban ideal comprising detached or semi-detached homes and high rise tower blocks. This architectural iconoclasm can be construed as a rather crude response to the indigenous spaces and builtform. The paper attempts to dismantle the current tension between traditional and contemporary 'culture' (and hence society) and housing (or builtform) in Kathmandu by engaging in a discussion that cuts across space, time and meaning of building. The paper concludes that residential architecture in Kathmandu today stands disoriented and lost in the transition.

Research by Peaceful Means: Methodologies in Peace Psychology

Methodologies in Peace Psychology (Bretherton & Law, 2016) offers a multidisciplinary perspective on the relation between research and methodologies, making it a useful read not only for those interested in peace psychology, but also for all researchers and practitioners interested in mixed and participative methods. The edited volume offers a multifaceted approach to the topic, incorporating global authors with different backgrounds and perspectives who are at diverse stages of their academic careers. Thus, it complements a traditional Western-focused approach, making a unique contribution to the literature.

Reconciliation's Contributions to Quality Peace

In this chapter we ask what unique contributions reconciliation can make toward building quality peace. We begin by briefly reviewing some of the diverse approaches to understanding the term reconciliation, and settle on a formulation consistent with the emerging perspective of a quality of peace. We then identify three levels – international, state-citizen, intergroup – at which reconciliation can impact peace. We explore how reconciliation may function at each level and how specific factors may advance a more robust and lasting peace process. We synthesize this analysis by identifying key aspects of reconciliation that advance our understanding of a quality of peace: inclusive participation, balancing symbolic and material actions, integrating psychosocial processes, and emphasizing generational approaches. The chapter concludes with suggestions of possible indicators and future research that may support the links between reconciliation and peace processes.

Mitochondrial Transfer via Tunneling Nanotubes (TNT) is an Important Mechanism by which Mesenchymal Stem Cells Enhance Macrophage Phagocytosis in the in vitro and in vivo Models of ARDS

Mesenchymal stromal cells (MSC) have been reported to improve bacterial clearance in pre-clinical models of Acute Respiratory Distress Syndrome (ARDS) and sepsis. The mechanism of this effect is not fully elucidated yet. The primary objective of this study was to investigate the hypothesis that the anti-microbial effect of MSC in vivo depends on their modulation of macrophage phagocytic activity which occurs through mitochondrial transfer. We established that selective depletion of alveolar macrophages (AM) with intranasal (IN) administration of liposomal clodronate resulted in complete abrogation of MSC anti-microbial effect in the in vivo model of E.coli pneumonia. Furthermore, we showed that MSC administration was associated with enhanced AM phagocytosis in vivo. We showed that direct co-culture of MSC with monocyte-derived macrophages (MDMs) enhanced their phagocytic capacity. By fluorescent imaging and flow cytometry we demonstrated extensive mitochondrial transfer from MSC to macrophages which occurred at least partially through TNT-like structures. We also detected that lung macrophages readily acquire MSC mitochondria in vivo, and macrophages which are positive for MSC mitochondria display more pronounced phagocytic activity. Finally, partial inhibition of mitochondrial transfer through blockage of TNT formation by MSC resulted in failure to improve macrophage bioenergetics and complete abrogation of the MSC effect on macrophage phagocytosis in vitro and the anti-microbial effect of MSC in vivo.

Collectively, this work for the first time demonstrates that mitochondrial transfer from MSC to innate immune cells leads to enhancement in phagocytic activity and reveals an important novel mechanism for the anti-microbial effect of MSC in ARDS.

Bringing down the walls: Is the notion of ‘promoting shared space’ commensurate with effective transformation of contested places in Belfast?

This article is a reflexive and critical examination of recent empirical research on effective practice in the management and ‘transformation’ of contested urban space at sectarian interfaces in Belfast. By considering the development of interfaces, the areas around them and policy responses to their persistence, the reality of contested space in the context of ‘peace building’ is apparent; with implications for local government as central to the statutory response. Belfast has developed an inbuilt absence of connectivity; where freedom of movement is particularly restricted and separation of contested space is the policy default position. Empirical research findings focus attention on the significance of social and economic regeneration and fall into three specific areas that reflect both long-term concerns within neighbourhoods and the need for adequate policy responses and action ‘on the ground’. Drawing on Elden and Sassen we reconfigure the analytical framework by which interfaces are defined, with implications for policy and practice in post-conflict Belfast. Past and current policy for peace-building in Northern Ireland, and transforming the most contested space, at interfaces in Belfast, is deliberately ambiguous and offers little substance having failed to advance from funding-led linguistic compliance to a sustainable peace-building methodology.
