Doctor of Philosophy / Department of Family Studies and Human Services / Walter R. Schumm / Abstract This study seeks to clarify a controversy in the literature about which characteristics of families are most responsible for facilitating the development of empathy in children. The study utilized a correlational research design and self-report questionnaires. The Balanced Emotional Empathy Scale measured the criterion variable, subjects’ levels of emotional empathy. The Circumplex Model of Marital and Family Systems’ accompanying questionnaire, the fourth version of the Family Adaptability and Cohesion Evaluation Scales (FACES IV) measured the two key predictor variables, levels of family cohesion and family flexibility, in the subjects’ families of origin. The central hypothesis of the Circumplex Model is that healthy family functioning would be predicted by balanced functioning on both of these key dimensions of family life. The first predictor variable, family cohesion, appears to encompass those factors emphasized by researchers who have asserted that positive family affective bonds would be the family characteristic most predictive of higher levels of empathy in children. The second predictor variable, family flexibility, appears to encompass those factors emphasized by researchers who have asserted that the style of parental discipline would be the family characteristic most predictive of higher levels of empathy in children. Participants in this study were all students at a mid-size, public, Midwestern university. A purposive convenience sample was utilized. Correlational statistics and multiple regression analyses were used to test hypotheses. The results suggested several conclusions. Balanced levels of family cohesion were positively associated with higher levels of emotional empathy, as predicted. The prediction that balanced levels of family flexibility would also be positively associated with higher levels of emotional empathy was not supported. Instead, higher levels of empathy were associated with a somewhat strict or rigid style of parental discipline. Various alternative explanations for these results are discussed, as are limitations of the study, recommendations for future research, and implications for practitioners.

Denna kvalitativa studie syftade till att undersöka två skolors verksamheter utifrån begreppet flexibilitet. Skolpersonal intervjuades med hjälp av sex semistrukturerade intervjuer om sina upplevelser av möjligt handlingsutrymme, samt bredd och variation av arbetsuppgifter. Studiens syfte var att ta reda på vilka lärprocesser och kompetenser som utvecklades för att hantera kravet på flexibilitet. Resultatet visade att skolpersonals arbete var oförutsägbart, föränderligt, varierande och kravfyllt från olika håll. Respondenterna fick utföra fler arbetsuppgifter av administrativ karaktär idag och deras yrkesroller har blivit komplexa och breddade. Många arbetade på sin fritid för att känna att de "hann med" arbetet. Upplevelsen var att organisationen inte var flexibel, men att den förväntade sig att medarbetarna var flexibla och att de arbetade för att nå målen med begränsat handlingsutrymme. Respondenterna menade att det krävs en större samverkan mellan utbildning och arbetsliv så att utbildningarna blir mer verklighetsförankrade och uppdaterade. Kollegor i form av arbetslag, tillsammans med erfarenhet, verkade vara det viktigaste för att uppleva hanterbarhet kring kraven på flexibilitet. Lärare upplevde, i större utsträckning än övrig personal, ett större handlingsutrymme och mer tid i arbetslaget. De hade därmed större möjlighet till utvecklingsinriktat lärande och kompetens som utveckling, snarare än anpassning. Andra yrkesgrupper menade att planeringstid och delaktighet i arbetslag krävs i större utsträckning för kompetensutveckling och utvecklingsinriktat lärande. Resultatet av denna studie visar likheter med tidigare forskning, men att det också finns behov av lärande – och kompetensutvecklingsstrategier kring komplexa arbeten, och hur skolpersonals yrken ska hanteras på ett sätt som är stärkande för professionen. Denna studie skulle kunna vara ett bidrag till underlag för en sådan forskning. / This qualitative study aimed to examine the organization of two schools by the term flexibility. School personnel was interviewed, using six semi-structured interviews, about their experiences of possible latitude and the breadth and variety of tasks. The study's purpose was to find out which learning processes and competences developed to cope with the requirement for flexibility. The study showed that school personnel work was unpredictable, changeable, diverse and demanding from different directions. The respondents had more tasks of an administrative nature nowadays and their professional roles have become complex and broadened. Many worked in their spare time to feel they "catch up" on work. It was felt that the organization wasn't flexible, but that it expected that employees were flexible and worked to achieve the goals with limited latitude. Respondents believed that a greater synergy between education and employment was required, so that the programs are more reality-based and updated.Colleagues, along with experience, appeared to be the most important to manage the requirements for flexibility. Teachers experienced, to a greater extent than other employees, more freedom and more time with colleagues and thus had greater opportunities for development-oriented learning and competence development, rather than adaptation-oriented learning. Other professionals believe that planning time and involvement in work teams is required to a greater extent for competence and learning development. This study has some similarities to earlier research, but it also shows that there is a need for more research in this area. There is a need for learning - and skills development strategies for complex jobs and how they should be managed in an empowering way. My study could be a contribution to a basis for such research.

This thesis examines the nature of transition expertise which enables individuals to make repeated successful transitions over the course of their career. It addressed four areas that contribute to transition expertise: 1) cognitive flexibility that enables the generalisation of expert knowledge and processes; 2) inferential and inductive cognitive mechanisms that enable expertise to be generalised; 3) personal intelligences that are used to support transitions; and 4) practical intelligence as it supports performance contextually during transitions. The study used retrospective interviews to gather data from elite performers in three fields who had made successful career transitions: sports people who become national coaches or heads of national bodies; successful musicians who become heads of faculty or principals of a conservatoire; successful business people who become senior vice presidents or CEOs. Participants were able to generalise expert knowledge and processes beyond their primary domains, contrary to widely held views about the domain specificity of expertise. Cognitive flexibility enabled this generalisation and was developed through broad based training, early exposure to multiple domains and the early use of generative cognitive processes during the development of primary domain expertise. Inductive, inferential and analogical cognitive mechanisms were the main tools through which expertise was generalised during transitions. Personal intelligence contributed to transition expertise. Intrapersonal intelligence enabled individuals to understand how their abilities, values and motivations shaped their career progression. Interpersonal intelligence enabled individuals to respond effectively to the requirements of their peers, direct reports, stakeholders and organisational context. Contrary to expectations, self regulatory processes did not play a central role in the management of transitions. Practical intelligence enabled transition expertise. It involved more than applying subject-area and tacit knowledge. It encompassed the abilities to: identify and resolve problems; manipulate environmental objects in the form of administrative tasks, schedules and plans; utilise resources in terms of people and materials; and shape their environment, corporate structures and culture. Transition expertise develops and evolves over the course of a career as it uses convergent and divergent cognitive processes, inductive mechanisms, personal awareness and cognitive pragmatics to address issues of increasing scope and implication. While motivational factors, self belief and personality resiliency are important contributors to transition expertise they did not form part of this study.

Personality is one of the most broad and complex areas in psychology. This has led to many researchers attempting to reduce this complexity by focusing solely on how habitual personality differs between each individual (inter-individual differences). This is important to study, but it has been focused on so heavily that research into how each individual personality varies within the person (intra-individual differences) has been neglected in comparison. Recent research has started to examine intra-individual variation in personality more thoroughly. One research aim of this programme was to establish the nature of several different types of within person variability including inter-item variation (variation within the test responses for a personality trait), and cross-contextual variation in personality (variation according to context), to see whether these types of variability are associated with psychological outcomes. Three research questions were examined to this end: 1) What is the extent of meaningful variability in personality trait test responding? 2) What are the predictors of intra-individual variability in personality? 3) What is the relative importance of the person and situational factors in personality variability? The first question was developed to try and determine whether the individual can display meaningful inter-item variation in ratings of specific behaviours within personality trait measures. Trait questionnaires are usually only analysed at the between subject level, and within subject variation in inter-item ratings have not been extensively examined in relation to meaningful psychological outcomes. The second and third questions were developed to look into the nature of cross-contextual personality, and establish whether within person personality differences are influenced more strongly by the person or situation. The studies conducted towards answering these questions demonstrated a person-based capacity to display intra-individual variability. A second aim of the research programme was to see whether the capacity to display these types of variability can be utilised in behaviour change. The fourth research question was developed to try and understand how a person can display intra-individual variability, yet still be resistant to changing negative habits: 4) How do the different aspects in personality variability help explain why some people are resistant to change, especially with regard to behaviours that are bad for them? This question was answered by theoretically discussing the findings from the three previous studies which proposed that positive or problematic behaviour could be interpreted with a simple path to understand the process of behavioural action: The individual receives feedback from a behaviour response which either validates or invalidates their action in the situation context (does or does not receive a desired outcome). Reinforcement of the behaviour happens if it is validated by positive feedback. Alternately reconstruction of the situation happens if the behaviour is invalidated. This allows for two types of intra-individual variability. One is flexibility in behaviour responses to different situations under the individual’s control. The other is change according to the situation, where the behaviour is invalidated and an alternative is attempted. A problematic behaviour may have benefit in stopping something invalidating, but if repeated it may become a habit needed for psychological functioning. As part of the second research aim a behaviour change strategy was developed and piloted to try and bring the individual closer to their construct of the ideal self. Instructions were provided for the individual to experiment with that differed from their disposition. The programmes had varied degrees of success depending on the participant. The implications for personality research and behaviour change are discussed.

This doctoral dissertation examines the mode and efficacy of environmental and climate policy in China’s automotive sector. The ascent of China’s automobile market to the largest worldwide has detrimental effects on the country’s energy security situation, worsens environmental pollution, and increases greenhouse gas emissions. Environmental and climate policy measures to ameliorate these repercussions are the most apt tools available to the Chinese government. The objective of this dissertation is to identify the dominant mode of environmental and climate policies in China’s automotive industry and to assess the efficacy of select policy instruments. It does so by asking whether a uniform national approach to policy instrument adoption can be discerned that reflects China’s institutional and administrative history or whether modal exceptions exist. Secondly, if modal differences exist, to what extent do different instruments confirm the current understanding of the advantages and pitfalls of individual policy instrument types? And finally, how do Chinese instruments compare to those in other ambits in terms of policy mode and instrument efficacy? The literature on policy instruments holds that, due to their alleged efficiency advantages, incentive-based instruments dominate the political agenda of industrialised countries and international organisations (environmental consensus). This favouring of flexible instruments in academic and political circles contrasts with an evident lack of incentive-based instruments in practice and an observed lack of efficiency of some of those instruments actually implemented. Moreover, the policy mode adopted in developing countries and emerging markets has not yet received sufficient academic attention despite significant differences in institutional design, enforcement capacities, resources, and development paths that may imply reason for modal deviation. Applying a blend of qualitative and quantitative social sciences research methods, I add the case of China to the comparative literature and show that command-and-control regulation indeed forms the backbone of environmental and climate policy in China’s automotive industry. At the same time, modal differences exist between national regulation and local/ municipal incentive-based policy as well as in the electric vehicle sector, which shows a trend towards more incentive-based instruments and flexibility mechanisms in conventional regulation. Compared to other ambits, China has established a relatively flexible policy regime, at least for the case of vehicle efficiency standards. For the time being, incentive-based instruments remain comparatively ineffective and flexibility mechanisms in conventional regulation have an erosive effect on instrument stringency.

Objective of the present study is the development of methods for the assessment of manufacturing systems complexity and the investigation of flexibility and complexity relationship. Towards this target, a complete approach based on information theory permitting the analytical, quantitative and systematic modeling and quantification of both static and dynamic manufacturing complexity is proposed. Static complexity concerns the structure of the manufacturing systems, namely the products, the processes, the resources that constitute the systems as well as their interconnections. Static complexity is treated as the information that is required for the description of a manufacturing system. Multi domain matrices modeling the relationships between products, processes and resources are formalized as networks following the notions of graph theory. The information content of each matrix is assessed employing Shannon entropy measure and their aggregation yields the static complexity. Dynamic complexity is related to the uncertainty in the behaviour of a manufacturing system and in the present study is associated with the unpredictability of the performance indicators timeseries. The unpredictability of the performance indicators timeseries, which are provided by computer simulation, is captured employing the Lempel Ziv algorithm that calculates the Kolmogorov complexity. The dynamic complexity is either the unpredictability of a specific timeseries or the weighted mean of a series of performance indicators timeseries produced under different product demand scenarios. The relationship between flexibility and complexity is investigated for a group of 19 different configurations of a manufacturing system. In particular, operation flexibility that refers to the system’s ability to produce a set of products through different machines, materials, operations and sequences of operations and total complexity, and both static and dynamic are examined employing a utility function. As a case study, two assembly lines producing three car floor model types at three different product mixes are investigated. The dynamic complexity of each assembly line is assessed and the relationship between product mix and dynamic complexity is studied. The evaluation of the case study revealed the efficiency of the suggested approach validated its applicability to industrial environments. / Αντικείμενο της παρούσας διατριβής είναι η ανάπτυξη μεθόδων για την εκτίμηση πολυπλοκότητας συστημάτων παραγωγής και η διερεύνηση της σχέσης ευελιξίας και πολυπλοκότητας. Προς αυτή την κατεύθυνση προτείνεται μια ολοκληρωμένη προσέγγιση βασισμένη στην θεωρία της πληροφορίας που επιτρέπει μια αναλυτική, ποσοτικοποιημένη και συστηματική προτυποποίηση και εκτίμηση τόσο της στατικής όσο και της δυναμικής πολυπλοκότητας των συστημάτων παραγωγής. Η στατική πολυπλοκότητα αφορά την δομή των συστημάτων παραγωγής, και σχετίζεται με τα προϊόντα, τις διεργασίες, τους παραγωγικούς πόρους που αποτελούν το σύστημα καθώς και τις μεταξύ τους σχέσεις. Η στατική πολυπλοκότητα αντιμετωπίζεται ως η πληροφορία που απαιτείται για να περιγραφεί ένα σύστημα παραγωγής. Πολυ-πεδιακοί πίνακες αναπαριστούν τις σχέσεις μεταξύ προϊόντων, διεργασιών και πόρων και προτυποποιούνται ως δίκτυα ακολουθώντας την θεωρία γράφων. Το πληροφοριακό περιεχόμενο κάθε πίνακα εκτιμάται με την χρήση της εντροπίας Shannon και το άθροισμα για όλους τους πίνακες δίνει την στατική πολυπλοκότητα. Η δυναμική πολυπλοκότητα σχετίζεται με την αβεβαιότητα της συμπεριφοράς των συστημάτων παραγωγής και στην παρούσα διατριβή συνδέεται με την απροβλεψιμότητα των χρονοσειρών δεικτών απόδοσης ενός συστήματος. Οι χρονοσειρές των δεικτών απόδοσης προκύπτουν από υπολογιστική προσομοίωση και η απροβλεψιμότητα τους εκτιμάται με των αλγόριθμο Lempel Ziv ο οποίος υπολογίζει την πολυπλοκότητα Kolmogorov. Η δυναμική πολυπλοκότητα είναι η απροβλεψιμότητα είτε μιας συγκεκριμένης χρονοσειράς είτε ο σταθμισμένος μέσος όρος ενός συνόλου χρονοσειρών δεικτών απόδοσης. Η σχέση ευελιξίας – πολυπλοκότητας διερευνάται για 19 διαμορφώσεις ενός συστήματος παραγωγής. Συγκεκριμένα, η ευελιξία λειτουργίας που αναφέρεται στην ικανότητα ενός συστήματος να παράγει ένα σύνολο προϊόντων χρησιμοποιώντας διαφορετικές μηχανές και διεργασίες και πολυπλοκότητα τόσο η στατική όσο και η δυναμική μελετώνται με μια συνάρτηση χρησιμότητας. Ως περίπτωση μελέτης εξετάζονται δύο γραμμές συναρμολόγησης που παράγουν τρία δάπεδα αμαξιού σε τρία μείγματα παραγωγής. Η δυναμική πολυπλοκότητα κάθε γραμμής και η σχέση μείγματος παραγωγής και δυναμικής πολυπλοκότητα μελετώνται. Η αξιολόγηση της περίπτωσης μελέτης αποδεικνύει την αποτελεσματικότητα των προτεινόμενων μεθόδων σε βιομηχανικό περιβάλλον.

While the gestural communication of apes is widely recognised as intentional and flexible, their vocal communication still remains considered as mostly genetically determined and emotionally bound. Trying to limit the direct projections of linguistic concepts, that are far from holding a unified view on what constitute human language, this thesis presents a detailed description of the pant-grunt vocalisation usage and development in the chimpanzees (Pan troglodytes schweinfurthii) of the Budongo forest, Uganda. Pant-grunts are one of the most social vocalisations of the chimpanzee vocal repertoire and are always given from a subordinate individual to a dominant. The question of how such a signal is used and develops is critical for our understanding of chimpanzee social and vocal complexity in an ontogenetical and phylogenetical perpective. Results suggest that pant-grunt vocalisations can be used in a flexible way, both in their form and usage within a social group. More specifically, chimpanzees seemed to take into account the number and identity of surrounding individuals before producing these vocalisations. At the acoustic level, pant-grunts seem to be very variable vocalisations that corresponded to different social situations commonly encountered. Grunts are one of the first vocalisations produced by babies but they are not first produced in social contexts. Although some modifications of the social grunts form and usage could not entirely be attributed to maturation only, the role of the mother seemed to be restricted. Her direct influence was perhaps more visible in the rhythmic patterns of chorusing events. Taken together, this thesis suggests that chimpanzee vocalisations are more flexible in their usage, production and acquisition than previously thought and might therefore be more similar to gestural communication.

Flexibility and Interoperability have become important characteristics for organisations and their business processes. The need to control flexible business processes within an organisation’s boundaries and between organisations imposes major requirements on a company’s process control capabilities. Workflow Management Systems (WFMS) try to fulfil these requirements by offering respective product features. Evidence suggests that the achievement of flexible business processes and an inter-organisational process control is also influenced by implementation processes for Workflow Management Applications (WFMA). [A WFMA comprises the WFMS and "all WFMS specific data with regard to one or more business processes" [VER01]]. The impact of a WFMA implementation methodology on the fulfilment of these requirements is the research scope of the project. The thesis provides knowledge in the following areas: 1. Review of the relationship between workflow management and the claim for process flexibility respectively -interoperability. 2. Definition of a research-/evaluation framework for workflow projects. This framework is composed of all relevant research variables that have been identified for the thesis. 3. Empirical survey of relevant workflow-project objectives and their priority in the context of process flexibility and –interoperability. 4. Empirical survey of the objectives’ achievement. 5. Empirical survey of methodologies / activities that have been applied within workflow projects. 6. Derivation of the project methodologies’ effectiveness in terms of the impact that applied activities had on project objectives. 7. Evaluation of existing workflow life-cycle models in accordance with the research framework. 8. Identification of basic improvements for workflow implementation processes with respect to the achievement of flexible and interoperable business processes. The first part of the thesis argues the relevance of the subject. Afterwards research variables that constitute the evaluation framework for WFMA implementation processes are stepwise identified and defined. An empirical study then proves the variables’ effectiveness for the achievement of process flexibility and –interoperability within the WFMA implementation process. After this the framework is applied to evaluate chosen WFMA implementation methodologies. Identified weaknesses and effective methodological aspects are utilised to develop generic methodological improvements. These improvements are later validated by means of a case study and interviews with workflow experts.

The nurturing of creative thinking skills is one of the cornerstones of Outcomes-Based Education (OBE). This study investigated to what extent teachers nurture the development of creative thinking through the choice of teaching methods, which include the application of teaching strategies and the utilization of resources, in the Grade 9 Social Sciences classroom. A literature study was undertaken to highlight the importance and nature of the development of creative thinking skills, and to establish which teaching methods, strategies and resources nurture the development of creative thinking in Social Sciences classrooms. The literature review provided the conceptual framework for the study, as well as the framework for designing a questionnaire that was utilized to obtain the perceptions of learners regarding the teaching methods, strategies and resources that their teachers use to nurture the development of creative thinking in the Grade 9 Social Sciences classroom. By means of a sequential explanatory mixed method research design, quantitative data were collected by means of a self-constructed questionnaire that was administrated to a convenient sample of a purposively selected group of Grade 9 Social Sciences learners (n=399) in the D7 district of the Gauteng Department of Education. Following this, a qualitative interview, which was constructed from the findings in the questionnaire, was conducted with purposively selected Grade 9 Social Sciences teachers (n=6) in order to ascertain the reasons behind the quantitative findings. The combination of quantitative and qualitative data revealed differences and similarities in opinion related to the teaching methods, strategies and resources that teachers use for nurturing creative thinking. In essence, the data revealed that teachers are, to some extent, nurturing creative thinking through their choice of teaching methods and strategies as well as the questioning techniques that they choose. However, the responses did not convincingly indicate to the researcher that the nurturing of creative thinking skills takes place on a regular and frequent basis. According to the learner responses, it appeared that teaching and learning methods and strategies that promote indirect, independent, interactive and experiential learning, are under-used by the Grade 9 Social Sciences teachers. In addition, resources that nurture creative elaboration such as political cartoons and photographs appear to be under-utilized. This study is concluded with recommendations to teachers concerning which teaching methods, strategies and resources could be implemented in order to promote the nurturing of creative thinking in the Grade 9 Social Sciences classroom. / Thesis (MEd (Learning and Teaching))--North-West University, Vaal Triangle Campus, 2013

Developing high-end aerospace components is a complex and highly competitive business. Hence methods for decreasing lead-time, while still providing the same quality and at a lower cost, has to be developed. This thesis is conducted at Research & Technology - GKN Aerospace in Trollhättan Sweden. A multidisciplinary analysis system known internally as Engineering Workbench, forms the base for implementation of the methods and tools developed in this thesis work. The system applies set-based engineering approach to develop new components. The evaluation of the design space is performed through parametric studies to find relations between the design parameters and performance metrics of the design. The engineering workbench allows GKN to define and evaluate a large design space within a limited timeframe. This thesis will look to improve the current producibility assessment system within the EWB by increasing the robustness and flexibility of the system. This is done by re-designing the producibility analysis part system and into a modular knowledge-based system that implements various techniques to increase the robustness and flexibility of the system. The re-designed system is automated, flexible and robust and is able to perform user defined weld assessments on a various designs and provides GKN with weld producibility data.
