Some analytical aspects of sampling plans

This thesis reports on the results of the analyses of certain aspects of sampling inspection plans. The investigation has been confined to attributes (as distinct from variables) plans and in this respect.the analyses have been concerned with two main aspects of single and double plans. These are:- (i) the Average Outgoing Quality Limit (AOQL) of the plan. (ii) the Average Sample Number (ASN) of the plan. In the former connection the investigation has been concerned with the evaluation of the AOQL analytically and the determination of the fraction defective of the incoming material to give the AOQL. The analyses have been applied to both single and double sampling plans, In the latter connection the investigation has been concerned with the evaluation of the maximum ASN analytically and the determination of the fraction defective of the incoming material to give the maximum value of ASN. The analyses have been confined only to double sampling plans because in the case of single sampling the ASN is constant and is equal to n, the sample size.

An evaluation of motivations for studying pharmacy, career commitment and future career plans

It has been predicted that there will be a full time pharmacist workforce shortage of over 15,000 by 2013. It is therefore necessary to recruit more students of a suitable calibre to undergraduate pharmacy degree courses. This study was designed to investigate the motivations of pre-university and MPharm students for studying pharmacy. A series of focus groups was conducted with Year 12 students and a national survey of Year 13, 1st year MPharm and 4th year MPharm students was undertaken. The study found that amongst Year 12 students, pharmacy is perceived as a background profession and was also perceived as being of a lower status than medicine and dentistry. It was concluded that there was a need for greater promotion of pharmacy as a career amongst pre-university students, including the provision of structured work experience placements. Analysis of UCAS applicant data for pharmacy shows that the applicant pool is buoyant and that the majority of applicants are female. Female respondents to the surveys were significantly more likely than males to wish to work part time if they had a family. This could lead to further shortages in the full time workforce. The largest ethnic group of applicants to pharmacy degree courses were Asian. Business ownership and self-employment were motivations for entering the procession of pharmacy and career aims for significantly more Asian than White respondents. Ownership of independent pharmacies is declining and this could be a barrier to future recruitment to pharmacy degree courses. A high degree of interest in locum working may present a problem for continuity in commissioned services within community pharmacy practice. Further work is needed to examine the motivations for working as a locum pharmacist.

The political shaping of energy technology:combined heat and power in Britain

There has been negligible adoption of combined heat and power (CHP) for district heating (DH) in Britain, despite continued advocacy. This thesis constructs an account of the treatment of the option, and devises a framework for explanation. Analysis of technological development and adoption, it is argued, should be similar to that of other social processes, and be subject to the same requirements and criticisms. They will, however, show features peculiar to the institutions developing and selecting technologies, their relation to different social groups, and the forms of knowledge in and about technology. Conventional approaches - organisation and interorganisation theories, and analyses of policy-making - give useful insights but have common limitations. Elements of an analytical framework situating detailed issues and outcomes in a structured historical context are derived from convergent radical critiques. Thus activity on CHP/DH is essentially shaped by the development and relations of energy sector institutions: central and local government, nationalised industries and particularly the electricity industry. Analysis of them is related to the specific character of the British state. A few CHP and DH installations were tried before 1940. During postwar reconstruction, extensive plans for several cities were abandoned or curtailed. In the 1960s and 70s, many small non-CHP DH schemes were installed on housing estates. From the mid-70s, the national potential of CHP/DH has been reappraised, with widespread support and favourable evaluations, but little practical progress. Significant CHP/DH adoption is shown to have been systematically excluded ultimately by the structure of energy provision; centralised production interests dominate and co-ordination is weak. Marginal economics and political commitment have allowed limited development in exceptional circumstances. Periods of upheaval provided greater opportunity and incentive for CHP/DH but restructuring eventually obstructed it. Explanation of these outcomes is shown to require analysis at several levels, from broad context to detailed action.

Relational incentive policies in cross-border interfirm relationships

How an exporter can effectively craft a distributor agreement that encourages its network of foreign distributors to respond in pro-relational ways? This is an important issue as previous research has shown that relationship quality was linked to export performance. However, research failed to propose managerial tools that allowed exporters to foster relational phenomena in cross-border relationships. In this study, we suggest that exporters can influence importers' attitudes and behaviors with relational incentives policies. We also show that the impact of these policies is impervious to the noise, i.e., psychic distance and information asymmetry, that characterizes international business relationships. Our hypotheses are tested via structural equations modeling with data from a sample of French exporters.

Increased salience of gains versus decreased associative learning differentiate bipolar disorder from schizophrenia during incentive decision making

Background Abnormalities in incentive decision making, typically assessed using the Iowa Gambling Task (IGT), have been reported in both schizophrenia (SZ) and bipolar disorder (BD). We applied the Expectancy-Valence (E-V) model to determine whether motivational, cognitive and response selection component processes of IGT performance are differentially affected in SZ and BD. Method Performance on the IGT was assessed in 280 individuals comprising 70 remitted patients with SZ, 70 remitted patients with BD and 140 age-, sex-and IQ-matched healthy individuals. Based on the E-V model, we extracted three parameters, 'attention to gains or loses', 'expectancy learning' and 'response consistency', that respectively reflect motivational, cognitive and response selection influences on IGT performance. Results Both patient groups underperformed in the IGT compared to healthy individuals. However, the source of these deficits was diagnosis specific. Associative learning underlying the representation of expectancies was disrupted in SZ whereas BD was associated with increased incentive salience of gains. These findings were not attributable to non-specific effects of sex, IQ, psychopathology or medication. Conclusions Our results point to dissociable processes underlying abnormal incentive decision making in BD and SZ that could potentially be mapped to different neural circuits. © 2012 Cambridge University Press.

Planning the neighbourhood economy:land-use plans and the economic potential of urban residential neighbourhoods in the Netherlands

This article investigates the relationship between zoning by-laws, as put forward in governmental land-use plans and the viability of urban residential neighbourhood economies. The Dutch planning tradition has long been characterized by strict separation of functions and top-down planning. We argue that profound changes in social and economic structures make land-use planning practices less suitable for the current policy formula of "mixed urban milieus". Although the residential neighbourhood might not be the location of large firms, it definitely attracts small ones, and facilitates starting businesses whose presence (and potential growth) can be beneficial to the city as a whole. We present a typology of spatial patterns of neighbourhood economies based on land-use plans and describe whether these are related to the distinctive economic development of the neighbourhood over the period 1999-2007. © 2013 Taylor & Francis.
