The aim of this study was to validate a scale of learning strategies, as derived from the educational literature, in an organizational context. Participants were 628 call centre employees. Both exploratory and confirmatory factor analyses suggested that a six-factor structure most accurately represented the learning strategies examined. Specifically, three cognitive (extrinsic work reflection, intrinsic work reflection, reproduction) and three behavioural strategies (interpersonal help seeking, help seeking from written material, practical application) were found.

Background Qualitative research makes an important contribution to our understanding of health and healthcare. However, qualitative evidence can be difficult to search for and identify, and the effectiveness of different types of search strategies is unknown. Methods Three search strategies for qualitative research in the example area of support for breast-feeding were evaluated using six electronic bibliographic databases. The strategies were based on using thesaurus terms, free-text terms and broad-based terms. These strategies were combined with recognised search terms for support for breast-feeding previously used in a Cochrane review. For each strategy, we evaluated the recall (potentially relevant records found) and precision (actually relevant records found). Results A total yield of 7420 potentially relevant records was retrieved by the three strategies combined. Of these, 262 were judged relevant. Using one strategy alone would miss relevant records. The broad-based strategy had the highest recall and the thesaurus strategy the highest precision. Precision was generally poor: 96% of records initially identified as potentially relevant were deemed irrelevant. Searching for qualitative research involves trade-offs between recall and precision. Conclusions These findings confirm that strategies that attempt to maximise the number of potentially relevant records found are likely to result in a large number of false positives. The findings also suggest that a range of search terms is required to optimise searching for qualitative evidence. This underlines the problems of current methods for indexing qualitative research in bibliographic databases and indicates where improvements need to be made.

The aim of this paper is to explore the engineering lecturers' experiences of generic skills assessment within an active learning context in Malaysia. Using a case-study methodology, lecturers' assessment approaches were investigated regarding three generic skills; verbal communication, problem solving and team work. Because of the importance to learning of the assessment of such skills it is this assessment that is discussed. The findings show the lecturers' initial feedback to have been generally lacking in substance, since they have limited knowledge and experience of assessing generic skills. Typical barriers identified during the study included; generic skills not being well defined, inadequate alignment across the engineering curricula and teaching approaches, assessment practices that were too flexible, particular those to do with implementation; and a failure to keep up to date with industrial requirements. The emerging findings of the interviews reinforce the arguments that there is clearly much room for improvement in the present state of generic skills assessment.

With few exceptions (e.g. Fincham & Clark, 2002; Lounsbury, 2002, 2007; Montgomery & Oliver, 2007), we know little about how emerging professions, such as management consulting, professionalize and establish their services as a taken-for-granted element of social life. This is surprising given that professionals have long been recognized as “institutional agents” (DiMaggio & Powell, 1983; Scott, 2008) (see Chapter 17) and professionalization projects have been closely associated with institutionalization (DiMaggio, 1991). Therefore, in this chapter we take a closer look at a specific type of entrepreneurship in PSFs; drawing on the concept of “institutional entrepreneurship” (DiMaggio, 1988; Garud, Hardy, & Maguire, 2007; Hardy & Maguire, 2008) we describe some generic strategies by which proto-professions can enhance their “institutional capital” (Oliver, 1997), that is, their capacity to extract institutionally contingent resources such as legitimacy, reputation, or client relationships from their environment.

The article looks first into the nature of the relations between Germany and the CEE countries a decade since the accession of the CEE countries to the EU. The relations are characterized as normalised and intensive with diverse levels of closeness and co-operation reflecting of the conceptual and ideological compatibility/differences. Next, the article focuses on the German attitude to the euro zone crisis. Germany has become a hegemon in the rescue effort aimed at stabilisation and economic invigoration of the euro zone. However, German hegemony has developed by default, not by design: her leading position is linked with considerable political and financial costs. Germany moved central stage and took the position of a reluctant hegemon. However, German role is contested internationally (it has not the support of the French government in key areas) as well as internally (particularly by the Federal Constitutional Court and the Bundesbank).The article argues that the new situation makes the German-CEE relations increasingly relevant for both sides. The German leadership of the EU increasing split along the north-south divide requires backing by the Northern group countries to which the CEE in general belongs. Given a number of reasons the CEE countries implement three distinctive strategies of co-operation with Germany in European politics. Also military co-operation, which remained rather limited so far, may receive new impulses, given the financial austerity. © 2013 The Regents of the University of California.

Inter-organisational knowledge transfer is very important for SMEs. However, compared to knowledge transfer within an organisation, its ‘boundary paradox’ makes its process more complicated and difficult to understand. In order to solve the ‘paradox’, inter-organisational knowledge transfer strategies need to be developed for SMEs. Through a review of the literature on knowledge transfer, this paper proposes an inter-organisational knowledge transfer process model that contains four stages (initiation, selection, interaction and conversion). It classifies three situations in which an SME exchanges knowledge with a customer (whether a larger company or an SME). It then applies a coordinating mechanism to analyse knowledge transfer strategies for the SME when it is a knowledgegiving firm and knowledge-receiving firm respectively, in the different stages of each situation.

The Foot-and-Mouth Disease (FMD) outbreak of 2001 in the UK was completely unprecedented in its scale and severity, with over four million animals culled and a cost to the Exchequer of over £4 billion. Local authorities were at the front line in dealing with the outbreak, in coordinating the cull of livestock, the disposal of carcasses as well as attempting to deal with its aftermath and, in particular, the impact on the wider rural economy. This article examines the impacts of this crisis on three local authorities, Devon, Herefordshire and Cumbria. It examines how far the crisis acted as a catalyst in developing strategies to deal with a future outbreak as well as new local initiatives to promote regeneration in the areas most adversely affected. It focuses on developments that can be directly attributed to the crisis and shows that FMD had a considerable impact on communications and 'joined-up' activity within local authorities and with local stakeholders. © 2006, LEPU, South Bank University.

This dissertation studies the process of operations systems design within the context of the manufacturing organization. Using the DRAMA (Design Routine for Adopting Modular Assembly) model as developed by a team from the IDOM Research Unit at Aston University as a starting point, the research employed empirically based fieldwork and a survey to investigate the process of production systems design and implementation within four UK manufacturing industries: electronics assembly, electrical engineering, mechanical engineering and carpet manufacturing. The intention was to validate the basic DRAMA model as a framework for research enquiry within the electronics industry, where the initial IDOM work was conducted, and then to test its generic applicability, further developing the model where appropriate, within the other industries selected. The thesis contains a review of production systems design theory and practice prior to presenting thirteen industrial case studies of production systems design from the four industry sectors. The results and analysis of the postal survey into production systems design are then presented. The strategic decisions of manufacturing and their relationship to production systems design, and the detailed process of production systems design and operation are then discussed. These analyses are used to develop the generic model of production systems design entitled DRAMA II (Decision Rules for Analysing Manufacturing Activities). The model contains three main constituent parts: the basic DRAMA model, the extended DRAMA II model showing the imperatives and relationships within the design process, and a benchmark generic approach for the design and analysis of each component in the design process. DRAMA II is primarily intended for use by researchers as an analytical framework of enquiry, but is also seen as having application for manufacturing practitioners.

This research project focused upon the design strategies adopted by expert and novice designers. It was based upon a desire to compare the design problem solving strategies of novices, in this case key stage three pupils studying technolgy within the United Kingdom National Curriculum, with designers who could be considered to have developed expertise. The findings helped to provide insights into potential teaching strategies to suit novice designers. Verbal protocols were made as samples of expert and novice designers solved a design problem and talked aloud as they worked. The verbalisations were recorded on video tape. The protocols were transcribed and segmented, with each segment being assigned to a predetermined coding system which represented a model of design problem solving. The results of the encoding were analysed and consideration was also given to the general design strategy and heuristics used by the expert and novice designers. The drawings and models produced during the generation of the protocols were also analysed and considered. A number of significant differences between the problem solving strategies adopted by the expert and novice designers were identified. First of all, differences were observed in the way expert and novice designers used the problem statement and solution validation during the process. Differences were also identified in the way holistic solutions were generated near the start of the process, and also in the cycles of exploration and the processes of integration. The way design and technological knowledge was used provided further insights into the differences between experts and novices, as did the role of drawing and modelling during the process. In more general terms, differences were identified in the heuristics and overall design strategies adopted by the expert and novice designers. The above findings provided a basis for discussing teaching strategies appropriate for novice designers. Finally, opportunities for future research were discussed.

This thesis is organised into three parts. In Part 1 relevant literature is reviewed and three critical components in the development of a cognitive approach to instruction are identified. These three components are considered to be the structure of the subject-matter, the learner's cognitive structures, and the learner's cognitive strategies which act as control and transfer devices between the instructional materials and the learner's cognitive structures. Six experiments are described in Part 2 which is divided into two methodologically distinct units. The three experiments of Unit 1 examined how learning from materials constructed from concept name by concept attribute matrices is influenced by learner or experimenter controlled sequence and organisation. The results suggested that the relationships between input organisation, output organisation and recall are complex and highlighted the importance of investigating organisational strategies at both acquisition and recall. The role of subjects previously acquired knowledge and skills in relation to the instructional material was considered to be an important factor. The three experiments of Unit 2 utilised a "diagramming relationships methodology" which was devised as one means of investigating the processes by which new information is assimilated into an individual's cognitive structure. The methodology was found to be useful in identifying cognitive strategies related to successful task performance. The results suggested that errors could be minimised and comprehension improved on the diagramming relationships task by instructing subjects in ways which induced successful processing operations. Part 3 of this thesis highlights salient issues raised by the experimental work within the framework outlined in Part 1 and discusses potential implications for future theoretical developments and research.

It is advantageous to develop controlled release dosage forms utilising site-specific delivery or gastric retention for those drugs with frequent or high dosing regimes. Cimetidine is a potent and selective H2 -reception antagonist used in the treatment of various gastrointestinal disorders and localisation in the upper gastrointestinal tract could significantly improve the drug absorption. Three strategies were undertaken to prepare controlled release systems for the delivery of cimetidine to the GI tract. Firstly, increasing the contact time of the dosage form with the mucus layer which coats the gastrointestinal tract, may lead to increased gastric residence times. Mucoadhesive microspheres, by forming a gel-like structure in contact with the mucus, should prolong the contact between the delivery system and the mucus layer, and should have the potential for releasing the drug in sustained and controlled manner. Gelatin microspheres were prepared, optimised and characterised for their physicochemical properties. Crosslinking concentration, particle size and cimetidine loading influenced drug release profiles. Particle size was influenced by surfactant concentration and stirring speed. Mucoadheisve polymers such as alginates, chitosans, carbopols and polycarbophil were incorporated into the microspheres using different strategies. The mucoadhesion of the microspheres was determined using in vitro surface adsorption and ex vivo rat intestine models. The surface-modification strategy resulted in highest levels of microsphere adhesion, with chitosan, carbopols and polycarbophil as the most successful candidates for improvement of adhesion, with over 70% of the microspheres retained ex vivo. Specific targeting agent UEA I lectin was conjugated to the surface of gelatin microspheres, which enhanced the adhesion of the microspheres. Alginate raft systems containing antacids have been used extensively in the treatment of gastro-oesophageal disease and protection of the oesophageal mucosa from acid reflux by forming a viscous raft layer on the surface of the stomach content, and could be an effective delivery system for controlled release of cimetidine.

Physically based distributed models of catchment hydrology are likely to be made available as engineering tools in the near future. Although these models are based on theoretically acceptable equations of continuity, there are still limitations in the present modelling strategy. Of interest to this thesis are the current modelling assumptions made concerning the effects of soil spatial variability, including formations producing distinct zones of preferential flow. The thesis contains a review of current physically based modelling strategies and a field based assessment of soil spatial variability. In order to investigate the effects of soil nonuniformity a fully three dimensional model of variability saturated flow in porous media is developed. The model is based on a Galerkin finite element approximation to Richards equation. Accessibility to a vector processor permits numerical solutions on grids containing several thousand node points. The model is applied to a single hillslope segment under various degrees of soil spatial variability. Such variability is introduced by generating random fields of saturated hydraulic conductivity using the turning bands method. Similar experiments are performed under conditions of preferred soil moisture movement. The results show that the influence of soil variability on subsurface flow may be less significant than suggested in the literature, due to the integrating effects of three dimensional flow. Under conditions of widespread infiltration excess runoff, the results indicate a greater significance of soil nonuniformity. The recognition of zones of preferential flow is also shown to be an important factor in accurate rainfall-runoff modelling. Using the results of various fields of soil variability, experiments are carried out to assess the validity of the commonly used concept of `effective parameters'. The results of these experiments suggest that such a concept may be valid in modelling subsurface flow. However, the effective parameter is observed to be event dependent when the dominating mechanism is infiltration excess runoff.
