Different Levels

Multiple theories of working memory are described in the chapters of this book and often these theories are viewed as being mutually incompatible, yet each is associated with a supporting body of empirical evidence. This chapter argues that many of these differences reflect different research questions, different levels of explanation, and differences in how participants perform their assigned tasks in different laboratories, rather than fundamental theoretical adversity. It describes a version of a multiple component working memory in which a range of specialized cognitive functions (or mental tools) act in concert, giving the impression, at a different level of explanation, of a unified cognitive system. The chapter argues that more rapid and more substantial scientific progress on the understanding of the concept of working memory would be achieved through identifying the levels of explanation explored within each theoretical framework, and attempting to integrate theoretical frameworks rather than perpetuating debate with no clear resolution in sight.

Materiality communicates complex information, often about the perspectives of people whose voices are silenced, or left off historical records. Material cultures provide indirect archives of such social histories, values and feelings. Examining the expressive qualities of material culture, we draw on data from the trans-national research project ‘Interfaith Childhoods’. This project generates and documents community perspectives on faith, identity and belonging. In response to our data generated through arts workshops with children and focus group discussions with parents, we develop a theoretical framework which observes how the materiality of religion can shape the ways young people and their parents build relationships with those from different religions. Here, we theorise how our empirical evidence makes a case for thinking through visual and material cultures of religion.

Russian Market

This paper examines the expansion (or internationalization) of Brazilian firms into the Russian market, by applying the revised model of Uppsala in the context of emerging economies. The study is an exploratory descriptive study based on case studies of four Brazilian meatpackers with operations in Russia. The results show that the revised model of Uppsala partially explains the internationalization of the firms studied. Some evidence regarding the influence of the business network was empirically found. However, some concepts proposed by the revised model, such as the manner in which a network limits company expansion, were not found. This study contributes empirical evidence to support the theoretical framework and opens avenues for further research on business networks among emerging countries.

Expert Surveys

Regional economic organizations (REOs) proliferate in the developed and developing world. However, there is wide variation in both their institutional structure and the degree to which they achieve their goals. This article presents a theoretical framework and empirical evidence to explain the variance in the institutional design and effectiveness of these agreements. It argues that the conditions that produce effective and broad agreements are not a function of design, but rather of exogenous factors. If countries within the REO have fewer options for world trade beyond the REO, they will develop strong institutions and make substantial use of them. This study presents a new cross-regional dataset, compiled from expert surveys, to test these arguments. It shows that expert evaluations of how well a REO functions - including its ability to meet its own goals and the ambition of those goals—hinge less on that agreement's legalization and more on the trade opportunities that REO members faced when the institution was formed.

Constant Proportion Portfolio Insurance

ABSTRACTIn recent years, Constant Proportion Portfolio Insurance (CPPI) has been the most widely recognised form of portfolio insurance among market practitioners, despite a lack of theoretical framework to support it. This paper presents a revised formulation of Option Based Portfolio Insurance (OBPI) and shows, through a case study, how it can be used as a structured product and applied in practice as a dynamic investment strategy for insurance and pensions funds such as with-profits funds. CPPI and the Revised Option Based Portfolio Insurance (ROBPI) technique adopted in this paper are similar in the sense that they rely on dynamic allocation between risky and risk-free assets to provide downside protection. Comparison between the two methods shows that ROPBI is more efficient and forward looking, giving more information about downside risk and producing less volatile asset allocation, which reduces transaction costs and any market impact.

The role of cultural group selection in explaining human cooperation is a hard case to prove

Theoretical Issues

AbstractWe believe cultural group selection is an elegant theoretical framework to study the evolution of complex human behaviours, including large-scale cooperation. However, the empirical evidence on key theoretical issues – such as levels of within- and between-group variation and effects of intergroup competition – is so far patchy, with no clear case where all the relevant assumptions and predictions of cultural group selection are met, to the exclusion of other explanations.
