The New Institutionalism and Africa
After briefly reviewing the new institutionalism, this article uses the history of political reform in Africa to test its key tenet: that power, if properly organised, is a productive resource. It does so by exploring the relationship between changes in political institutions and changes in economic performance, both at the macro- and the micro level. The evidence indicates that political reform (Granger) causes increases in GDP per capita in the African subset of global data. And, at the micro level, it demonstrates that changes in national political institutions in Africa strongly relate to changes in total factor productivity in agriculture.African and African American StudiesGovernmen

The State of Democracy in Sub-Saharan Africa
Africa experienced a wave of democratization over the past 20 years and this increase in democracy, we find, positively and significantly affects income per capita. Our dynamic panel data results suggest that countries only slowly converge to their long-run income values as predicted by current democracy levels, however. African countries may therefore be currently too democratic relative to their income levels. In keeping with this possibility, a significant number of countries are experiencing political ‘back sliding’: elections are won by the use of illicit tactics, term limits on political leaders have been overturned and there have been unconstitutional seizures of power.Governmen
Exploring rationales for branding a university: Should we be seeking to measure branding in UK universities?
Although branding is now widespread among UK universities, the application of branding principles in the higher education sector is comparatively recent and may be controversial for internal audiences who question its suitability and efficiency.
This paper seeks to investigate how and whether the effectiveness of branding activity in the higher education sector should be evaluated and measured, through exploratory interviews with those who often drive it; UK University marketing professionals.
Conclusions suggest that university branding is inherently complex and therefore application of commercial approaches may be over simplistic. Whilst marketing professionals discuss challenges they do not necessarily have a consistent view of the objectives of branding activity although all were able to clearly articulate branding objectives for their university, including both qualitative and, to some extent, quantitative metrics. Some measures of the real value of branding activity are therefore suggested but a key debate is perhaps whether the objectives and role of branding in higher education needs to be clarified, and a more consistent view of appropriate metrics reached? Various challenges in implementing branding approaches are also highlighted
How and When Socially Entrepreneurial Nonprofit Organizations Benefit From Adopting Social Alliance Management Routines to Manage Social Alliances?
Social alliance is defined as the collaboration between for-profit and nonprofit organizations. Building on the insights derived from the resource-based theory, we develop a conceptual framework to explain how socially entrepreneurial nonprofit organizations (SENPOs) can improve their social alliance performance by adopting strategic alliance management routines. We test our framework using the data collected from 203 UK-based SENPOs in the context of cause-related marketing campaign-derived social alliances. Our results confirm a positive relationship between social alliance management routines and social alliance performance. We also find that relational mechanisms, such as mutual trust, relational embeddedness, and relational commitment, mediate the relationship between social alliance management routines and social alliance performance. Moreover, our findings suggest that different types of social alliance motivation can influence the impact of social alliance management routines on different types of the relational mechanisms. In general, we demonstrate that SENPOs can benefit from adopting social alliance management routines and, in addition, highlight how and when the social alliance management routines–social alliance performance relationship might be shaped. Our study offers important academic and managerial implications, and points out future research directions
Protease-activated receptor-2 mediates the expression of inflammatory cytokines, antimicrobial peptides, and matrix metalloproteinases in keratinocytes in response to Propionibacterium acnes
Propionibacterium acnes (P. acnes) has been known to produce various exogenous proteases, however, their role in acne pathogenesis remains largely unknown. Proteases elicit cellular responses, at least in part, via proteinase-activated receptor-2 (PAR-2), which is known to mediate inflammation and immune response. In this study, we investigated whether proteases from P. acnes could activate PAR-2 on keratinocytes and induce pro-inflammatory cytokines, antimicrobial peptides (AMPs), and matrix metalloproteinases (MMPs) via PAR-2 signaling. We examined PAR-2 expression and protease activity in acne lesions using immunofluorescence staining and in situ zymography. The effect of the culture supernatant of P. acnes on Ca2+ signaling in immortalized keratinocytes (HaCaT) was measured using a fluorescence method. HaCaT cells were treated with P. acnes strain ATCC 6919 culture supernatant, with or without pretreatment with serine protease inhibitor or selective PAR-2 antagonist and the gene expression of pro-inflammatory cytokines, AMPs, and MMPs was detected using real-time reverse transcription-polymerase chain reaction. We found that the protease activity and PAR-2 expression were increased in acne lesions. The P. acnes culture supernatant induced calcium signaling in keratinocytes via PAR-2 and stimulated the mRNA expression of interleukin (IL)-1α, -8, tumor necrosis factor (TNF)-α, human beta defensin (hBD)-2, LL-37, MMP-1, -2, -3, -9, and -13 in keratinocytes, which was significantly inhibited by serine protease inhibitor as well as selective PAR-2 specific antagonist. These results indicate that PAR-2 plays an important role in the pathogenesis of acne by inducing inflammatory mediators in response to proteases secreted from P. acnes

International Assistance After Conflict: Health, Transitional Justice, and Opportunity Costs
After violent conflicts, international actors face difficult choices about whether and how to provide assistance. These decisions can have immense consequences. As aid always occurs under conditions of scarcity, theoretical reflection is crucial to reveal the opportunity costs and potential tensions between alternative courses of action. Yet, there has been relatively little scholarly reflection on what should constitute priorities for post-conflict assistance and why. This paper advances this debate by comparing two very different areas of assistance that both embody compelling values and goals: public health and transitional justice. It argues that aid for public health deserves greater attention based on powerful normative considerations and its impressive empirical record. It also suggests the need to examine not only clearly underperforming areas, but also tough cases. Transitional justice, despite its strong normative foundations, faces challenges and limitations that justify reform and a reconsideration of the emphasis commonly placed on it. Our intention is not to suggest that long-standing commitments ought to be abandoned or that all aid should be allocated to health. Rather, by scrutinizing the priorities of international assistance, we hope to start a general discussion about how the international community can best help societies heal after conflict
Inducible cAMP Early Repressor (ICER) and Brain Functions
The inducible cAMP early repressor (ICER) is an endogenous repressor of cAMP-responsive element (CRE)-mediated gene transcription and belongs to the CRE-binding protein (CREB)/CRE modulator (CREM)/activating transcription factor 1 (ATF-1) gene family. ICER plays an important role in regulating the neuroendocrine system and the circadian rhythm. Other aspects of ICER function have recently attracted heightened attention. Being a natural inducible CREB antagonist, and more broadly, an inducible repressor of CRE-mediated gene transcription, ICER regulates long-lasting plastic changes that occur in the brain in response to incoming stimulation. This review will bring together data on ICER and its functions in the brain, with a special emphasis on recent findings highlighting the involvement of ICER in the regulation of long-term plasticity underlying learning and memory
