The Review of Economic Performance and Social Progress 2002: Towards a Social Understanding of Productivity

In this chapter, Quentin Grafton, Stephen Knowles and Dorian Owen examine the implications for productivity arising from the level of social diversity along a variety of dimensions, including ethnic, linguistic and religious differences and inequalities between rich and poor. Their basic intuition is that human beings tend to associate and communicate most readily with people similar to themselves, and their hypothesis is therefore that "social divergence" generates social barriers to communication among groups, inhibiting the diffusion of knowledge and lowering the level of productivity in the economy. As a consequence, the more diverse the society and the greater the number of distinct social groups, the higher are the communication costs and the greater are the barriers to the exchange of ideas and innovation.Social Divergence, Social Values, Social Capital, Total Factor Productivity, Multifactor Productivity, Multi-factor Productivity, Fractionalization, Homogeneity, Heterogeneity, Productivity, Labour Productivity, Labor Productivity, Growth, Inequality, Educational Inequality, Networks, Trust, Social Networks, Language, Education, Religion, Social Cohesion, Cohesion

Has multiculturalism failed in Britain?

This paper subjects the criticisms advanced against multiculturalism to empirical test. It asks whether ethno-religious groups lead ?parallel lives? and, in consequence, fail to integrate with the wider society. It looks in particular at the alleged corrosive effects of multiculturalism, specifically at the maintenance of an ethnic rather than a British identity, social distance from white people and willingness to contemplate violent protest, but finds that all groups alike have displayed major change across the generations in the direction of a British identity and reduced social distance. It finds no evidence that rates of intergenerational change have been slower among ethno-religious groups that have made successful claims for cultural recognition. In contrast, lower levels of integration are associated with perceptions of individual or group discrimination

An Experimental Study of Coconut Shell with Sugarcane Bagasse Ash as Partial Replacement of Coarse Aggregates and Cement to Concrete

High building material costs and demand can be a significant disadvantage for builders and contractors. The cost of raw materials such as wood, steel, and concrete is always growing, increasing the cost of projects. Due to the high demand for certain materials, they can be difficult to get on time, causing project delays. This is especially true when working on large-scale projects with short deadlines. This research presents an idea to minimize the problem by partially replacing the cement and coarse aggregates with sugarcane bagasse ash and coconut shell. The study has 3 main objectives: (1) To determine the effects of workability (slump cone test) and durability (water absorption test) of concrete when Coconut Shell and Sugarcane Bagasse Ash are used as partial replacements of cement and coarse aggregates after 7, 14, and 28 days of curing.The samples were tested using a Universal Testing Machine (UTM) and the outcomes of the experiment revealed that CS and SCBA have a positive result on the properties of standard concrete

SmartEx: a case study on user profiling and adaptation in exhibition booths

An investigation into user profiling and adaptation with exhibition booth as a case study is reported. First a review of the field of exhibitions and trade fairs and a summary introduction to adaptation and profiling are given. We then introduce three criteria for the evaluation of exhibition booth: effectiveness, efficiency and affect. Effectiveness is related the amount of information collected, efficiency is a measurement of the time taken to collect the information, and affect is the perception of the experience and the mood booth visitors have during and after their visit. We have selected these criteria to assess adaptive and profiled exhibition booths, we call smart exhibition (SmartEx). The assessment is performed with an experiment with three test conditions (non-profiled/non adaptive, profiled/non-adaptive and profiled adaptive presentations). Results of the experiment are presented along discussion. While there is significant improvements of effectiveness and efficiency between the two-first test conditions, the improvement is not significant for the last test condition, for reasons explained. As for the affect, the results show that it has an under-estimated importance in people minds and that it should be addressed more carefully

Elite athletes' genetic predisposition for altered risk of complex metabolic traits

BACKGROUND: Genetic variants may predispose humans to elevated risk of common metabolic morbidities such as obesity and Type 2 Diabetes (T2D). Some of these variants have also been shown to influence elite athletic performance and the response to exercise training. We compared the genotype distribution of five genetic Single Nucleotide Polymorphisms (SNPs) known to be associated with obesity and obesity co-morbidities (IGF2BP2 rs4402960, LPL rs320, LPL rs328, KCJN rs5219, and MTHFR rs1801133) between athletes (all male, n = 461; endurance athletes n = 254, sprint/power athletes n = 207), and controls (all male, n = 544) in Polish and Russian samples. We also examined the association between these SNPs and the athletes’ competition level (‘elite’ and ‘national’ level). Genotypes were analysed by Single-Base Extension and Real-Time PCR. Multinomial logistic regression analyses were conducted to assess the association between genotypes and athletic status/competition level. RESULTS: IGF2BP2 rs4402960 and LPL rs320 were significantly associated with athletic status; sprint/power athletes were twice more likely to have the IGF2BP2 rs4402960 risk (T) allele compared to endurance athletes (OR = 2.11, 95% CI = 1.03-4.30, P <0.041), and non-athletic controls were significantly less likely to have the T allele compared to sprint/power athletes (OR = 0.62, 95% CI =0.43-0.89, P <0.0009). The control group was significantly more likely to have the LPL rs320 risk (G) allele compared to endurance athletes (OR = 1.26, 95% CI = 1.05-1.52, P <0.013). Hence, endurance athletes were the “protected” group being significantly (p < 0.05) less likely to have the risk allele compared to sprint/power athletes (IGF2BP2 rs4402960) and significantly (p < 0.05) less likely to have the risk allele compared to controls (LPL rs320). The other 3 SNPs did not show significant differences between the study groups. CONCLUSIONS: Male endurance athletes are less likely to have the metabolic risk alleles of IGF2BP2 rs4402960 and LPL rs320, compared to sprint/power athletes and controls, respectively. These results suggest that some SNPs across the human genome have a dual effect and may predispose endurance athletes to reduced risk of developing metabolic morbidities, whereas sprint/power athletes might be predisposed to elevated risk

What is the 'dominant model' of British policymaking? Comparing majoritarian and policy community ideas

The aim of this article is to help identify the fundamental characteristics of the British policymaking system. It highlights an enduring conflict of interpretation within the literature. On the one hand, most contemporary analysts argue that the ‘Westminster model' is outmoded and that it has been replaced by modern understandings based on ‘governance'. On the other, key ideas associated with the Westminster model, regarding majoritarian government and policy imposition, are still in good currency in the academic literature, which holds firm to Lijphart's description of the United Kingdom as a majoritarian democracy. These very different understandings of British government are both commonly cited, but without much recognition that their conclusions may be mutually incompatible. To address this lack of comparison of competing narratives, the article outlines two main approaches to describe and explain the ‘characteristic and durable' ways of doing things in Britain: the ‘policy styles' literature initiated by Richardson in Policy Styles in Western Europe and the Lijphart account found in Democracies and revised in 1999 as Patterns of Democracy. The article encourages scholars to reject an appealing compromise between majoritarian and governance accounts

Evidence Use and the Institutions of the State: The Role of Parliament and the Judiciary

This chapter explores the role of parliaments and the judiciary in shaping evidence use in health policy making. Most analyses of the role of scientific evidence focus on the executive, i.e. national governments and ministries of health, as the key state actors in health policy and health system governance. This chapter shifts attention to the other two powers within the state, the legislative and the judiciary. Using the examples analysed in this book the chapter examines how parliaments can use evidence to inform legislative processes and to hold governments to account, although there are substantial differences between countries and political systems. However, there was little suggestion that such approaches were undertaken systematically. In cases in which policies are brought to court, judges may have to deal with scientific evidence within a country’s legal and constitutional framework, again with significant differences between national legal practices
