The connections between science and civic culture in the Victorian period have been extensively, and intensively, investigated over the past several decades. Limited attention, however, has been paid to Irish urban contexts. Roman Catholic attitudes towards science in the nineteenth century have also been neglected beyond a rather restricted set of thinkers and topics. This paper is offered as a contribution to addressing these lacunae, and examines in detail the complexities involved in Catholic engagement with science in Victorian Belfast. The political and civic geographies of Catholic involvement in scientific discussions in a divided town are uncovered through an examination of five episodes in the unfolding history of Belfast's intellectual culture. The paper stresses the importance of attending to the particularities of local politics and scientific debate for understanding the complex realities of Catholic appropriations of science in a period and urban context profoundly shaped by competing political and religious factions. It also reflects more generally on how the Belfast story supplements and challenges scholarship on the historical relations between Catholicism and science.

The bladder mucosa consists of the urothelium, basement membrane, and lamina propria (LP). Although the urothelium has been given much attention, it may be regarded as one part of a signaling system involving another equally important component of the bladder mucosa, namely, the LP. The LP lies between the basement membrane of the mucosa and the detrusor muscle and is composed of an extracellular matrix containing several types of cells, including fibroblasts, adipocytes, interstitial cells, and afferent and efferent nerve endings. In addition, the LP contains a rich vascular network, lymphatic vessels, elastic fibers, and smooth muscle fascicles (muscularis mucosae). The roles of the LP and its components in bladder function have not been definitively established, though it has been suggested to be the capacitance layer of the bladder, determining bladder compliance and enabling adaptive changes to increasing volumes. However, the bladder LP may also serve as a communication center, with an important integrative role in signal transduction to the central nervous system (nociception, mechanosensation). The LP may also, by means of its different components, make it possible for the urothelium to transmit information to other components of the bladder wall, contributing to activation of the detrusor muscle. In addition, the LP may serve as a source for production of factors influencing the growth of both the overlying urothelium and the underlying detrusor muscle.

Efficient formation of early GCs depends on the close interaction between GC B cells and antigen-primed CD4+ follicular helper T cells (TFH). A tight and stable formation of TFH/B cell conjugates is required for cytokine-driven immunoglobulin class switching and somatic hypermutation of GC B cells. Recently, it has been shown that the formation of TFH/B cell conjugates is crucial for B-cell differentiation and class switch following infection with Leishmania major parasites. However, the subtype of DCs responsible for TFH-cell priming against dermal antigens is thus far unknown. Utilizing a transgenic C57BL/6 mouse model designed to trigger the ablation of Langerin+ DC subsets in vivo, we show that the functionality of TFH/B cell conjugates is disturbed after depletion of Langerhans cells (LCs): LC-depleted mice show a reduction in somatic hypermutation in B cells isolated from TFH/B cell conjugates and markedly reduced GC reactions within skin-draining lymph nodes. In conclusion, this study reveals an indispensable role for LCs in promoting GC B-cell differentiation following cutaneous infection with Leishmania major parasites. We propose that LCs are key regulators of GC formation and therefore have broader implications for the development of allergies and autoimmunity as well as for future vaccination strategies.

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.

The efficiency of solar-energy-conversion devices depends on the absorption region and intensity of the photon collectors. Organic chromophores, which have been widely stabilized on inorganic semiconductors for light trapping, are limited by the interface between the chromophore and semiconductor. Herein we report a novel orange zinc germanate (Zn-Ge-O) with a chromophore-like structure, by which the absorption region can be dramatically expanded. Structural characterizations and theoretical calculations together reveal that the origin of visible-light response can be attributed to the unusual metallic Ge-Ge bonds which act in a similar way to organic chromophores. Benefiting from the enhanced light harvest, the orange Zn-Ge-O demonstrates superior capacity for solar-driven hydrogen production.

Higher education in the UK is in a state of flux and this is having particular impact on the humanities. On the one hand the pressure to support a STEM agenda is seen by some as forcing higher education down a narrow economic agenda, while government requirements for assessing the social and economic impact of research has raised concerns about excessive utilitarianism and a downgrading of ‘disinterested enquiry’. This paper argues that these concerns may be misplaced. The research impact agenda has the potential to promote more socially engaged research and more democratic engagement in the creation and dissemination of knowledge. In the US concerns about the democratic role of higher education more often seem to focus on the student experience. By contrast, in the UK concerns about citizenship education and democratic participation more often focus on high school students, perhaps because university students are more likely to have a formal role in institutional governance. The paper concludes that the papers in this forum have a very American feel, but the issues they address resonate on a much wider scale.

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.
