The role of market orientation in developing and sustaining market relationships : an empirical study in Taiwan

Ting, Shuyun January 2008 (has links)
Significant work has taken place in the development of our understanding of business dyadic relationships but much work remains to be done in determining the antecedents, particularly our understanding of cultural contexts. This research aims to add to the debate about what counts in developing a long-term orientation in channel relationships by investigating the role of the concept of market orientation; it explores the possible interface existing between the marketing concept and development of channel relationships. The context is relationships between distributors and suppliers in Taiwan. This study examines the relationship literature from a social exchange theoretical perspective and conducts multiple-case in-depth interviews at the dyadic ends to develop an integrated research model for analysing potential effects of market orientation on the relationship factors influencing long-term oriented relationship building. Quantitative mixed-mode questionnaire surveys were undertaken to test the research model and hypotheses drawn from the model. Data were collected from 158 distributors from four selected business sectors, including both commodity and noncommodity ones. The results confirm the applicability of the marketing concept to an eastern country: Taiwan, and provide empirical evidence that adoption of the marketing concept can be a strategy for stimulating and sustaining long-term oriented channel relationships while mediated by a number of relationship constructs. Communication and shared value are highlighted as the primary mediators while satisfaction signals an inclination to continue a relationship. Market orientation is found to exert significant direct effects on communication and shared value and indirect effects on the other relationship components: trust, cooperation, commitment, conflict and satisfaction, which all contribute to a continuing relationship.

Exploiting abstract syntax trees to locate software defects

Shippey, Thomas Joshua January 2015 (has links)
Context. Software defect prediction aims to reduce the large costs involved with faults in a software system. A wide range of traditional software metrics have been evaluated as potential defect indicators. These traditional metrics are derived from the source code or from the software development process. Studies have shown that no metric clearly out performs another and identifying defect-prone code using traditional metrics has reached a performance ceiling. Less traditional metrics have been studied, with these metrics being derived from the natural language of the source code. These newer, less traditional and finer grained metrics have shown promise within defect prediction. Aims. The aim of this dissertation is to study the relationship between short Java constructs and the faultiness of source code. To study this relationship this dissertation introduces the concept of a Java sequence and Java code snippet. Sequences are created by using the Java abstract syntax tree. The ordering of the nodes within the abstract syntax tree creates the sequences, while small sub sequences of this sequence are the code snippets. The dissertation tries to find a relationship between the code snippets and faulty and non-faulty code. This dissertation also looks at the evolution of the code snippets as a system matures, to discover whether code snippets significantly associated with faulty code change over time. Methods. To achieve the aims of the dissertation, two main techniques have been developed; finding defective code and extracting Java sequences and code snippets. Finding defective code has been split into two areas - finding the defect fix and defect insertion points. To find the defect fix points an implementation of the bug-linking algorithm has been developed, called S + e . Two algorithms were developed to extract the sequences and the code snippets. The code snippets are analysed using the binomial test to find which ones are significantly associated with faulty and non-faulty code. These techniques have been performed on five different Java datasets; ArgoUML, AspectJ and three releases of Eclipse.JDT.core Results. There are significant associations between some code snippets and faulty code. Frequently occurring fault-prone code snippets include those associated with identifiers, method calls and variables. There are some code snippets significantly associated with faults that are always in faulty code. There are 201 code snippets that are snippets significantly associated with faults across all five of the systems. The technique is unable to find any significant associations between code snippets and non-faulty code. The relationship between code snippets and faults seems to change as the system evolves with more snippets becoming fault-prone as Eclipse.JDT.core evolved over the three releases analysed. Conclusions. This dissertation has introduced the concept of code snippets into software engineering and defect prediction. The use of code snippets offers a promising approach to identifying potentially defective code. Unlike previous approaches, code snippets are based on a comprehensive analysis of low level code features and potentially allow the full set of code defects to be identified. Initial research into the relationship between code snippets and faults has shown that some code constructs or features are significantly related to software faults. The significant associations between code snippets and faults has provided additional empirical evidence to some already researched bad constructs within defect prediction. The code snippets have shown that some constructs significantly associated with faults are located in all five systems, and although this set is small finding any defect indicators that transfer successfully from one system to another is rare.

The integration of personal and professional ethical decision making constructs in trainee clinical psychologists

Jenkin, Angela January 2018 (has links)
Ethical decision-making is an important but challenging aspect of the role of a clinical psychologist. Little research has been conducted concerning how clinical psychologists make ethical decisions, with even less known about how trainees manage the process during professional training. The current study aimed to examine how trainees make ethical decisions, and how this process differs between more and less experienced trainees. Thirty-nine trainee clinical psychologists were recruited from a total of 17 doctoral training programmes in the United Kingdom. The sample recruited was demographically similar to the training population. A cross-sectional design was used to examine differences between first year (n = 19) and third year (n = 20) trainees. An online version of The Defining Issues Test questionnaire (DIT-2, Rest et al., 1999) was used to measure level of sophistication of ethical development, and individual face to face or Skype repertory grid interviews examined the integration of trainees’ personal and professional ethical decision-making construct subsystems. The vast majority of trainees were found to adopt a sophisticated approach to ethical decision-making, with half of all ethical decisions made from within a postconventional schematic approach. However, a small minority operated from within schemata based on maintenance of societal norms or personal interests. A deterioration in sophistication of thinking was demonstrated for more experienced trainees. Less experienced trainees were found to rely comparatively more heavily on their personal construct subsystems than more experienced trainees and vice versa. Increased integration between the subsystems over the course of training was demonstrated. The study demonstrates support for an acculturation process occurring throughout training. Implications of this and ideas for future research are discussed.

Ariadne’s Thread: Women and Labyrinths in the Fiction of A.S. Byatt and Iris Murdoch

Tomazic, Elizabeth Mary, res.cand@acu.edu.au January 2005 (has links)
This thesis is an investigation of the journeys towards a sense of identity or selfhood, achieved through honest and accurate appreciation of the lives of others, made by several female characters in the fiction of A.S. Byatt and the late Iris Murdoch. I believe that because Byatt and Murdoch value literature as a serious business that teaches as well as entertains, their writing can play a significant role in illuminating the lives of women by means of its portrayal of the resolution of women’s struggles. Women’s lives, despite the rise of feminism, are still not equitable. While many women strive to attain a balance of independence and intimacy – what Thelma Shinn calls a “meronymic” relationship – and connection within community, many do not succeed in this endeavour. The numerous challenges they face are difficult and confronting, and the stories of their efforts resemble journeys through a labyrinth or maze. Byatt acknowledges Murdoch as her literary mother, frequently citing Murdoch’s belief in the ability of literature to improve human life. While Byatt and Murdoch are interested in what characters learn about their relations to others and the world, they make it clear that characters are constructs, not real people. Yet their fiction is an ongoing exploration of the nature of reality and the nature of selfhood, particularly that of women. According to feminist theories, women are more constrained than men, and are therefore the focus of this study, but their experience of constraint is a more complex matter than experience of mere undifferentiated oppression, and is better represented by the structure of the labyrinth than that of the simple, linear journey. I agree with Byatt’s and Murdoch’s view of the importance of fiction as a means of commenting on human relationships, particularly with the notion of the need for connection within community. The labyrinth, together with the Bildungsroman, provides a paradigm for the complex experiences of Byatt’s and Murdoch’s female characters. All the characters in this study struggle to flee from restraint, seek purpose and agency in the world through interaction with others, and escape a feminised Plato’s Cave by learning to see more accurately, and all but one emerge from the maze into an autonomous and independent existence in community with others.

Business Relationships in the context of De-internationalization : A Case Study of Swedish SMEs

Deplasse, Julien, Jacinaite, Lina January 2013 (has links)
Every firm in the world in one way or another is touched by the prevailing globalization trend. In order to survive in the 21st century businesses in every industry are taking steps to expand through trade outside their home markets.  Thus this global expansion evokes stimulus by firms to internationalize. The internationalization process of firms has been studied extensively among various business scholars with the main focus on the growth or positive development of firms. However, an area which has received fairly limited attention is the de-internationalization process. In this field the role of small and medium sized enterprises (SMEs) under non-crisis conditions, where this phenomenon is seen as a strategic decision of firms or subsequence of internationalization process rather than a market failure, has been underestimated. This paper aims to contribute to the theoretical understanding of cross-border activities of small firms by looking into business relationships as a new perspective on analyzing de-internationalization motives. This was studied through a qualitative case study of Swedish SMEs operating globally. Interviews with sales and marketing directors of the companies together with secondary data compose the gathered empirical data for analyzing de-internationalization process. The study sheds light on business relationship constructs - dependence, bond, investment, and atmosphere - and their influence on the key factors for internationalization - trust, knowledge and commitment - which in turn determine the strategic decision by firms to reduce their market involvement in foreign markets. It has been found out that these key factors of internationalization were affected by the relationship constructs mostly negatively: the market knowledge in majority of cases was lacking due to the weak bond, the commitment determined by unbalanced dependence and reduced investment has gradually decreased along the time and the level of trust influenced by a negative atmosphere was not sufficient enough which played a decisive role on the reduced level of market involvement by firms. Thus the results of the study indicate that unfortunate business relationships influenced the decision of three case companies to de-internationalize through the key factors of internationalization.

Preferences And Evaluation Criteria Of Preschool Children Related To Different Types Of Play Materials

Ozan, Ezgi 01 September 2008 (has links) (PDF)
In this study, semi-structured interviews adopted from repertory grid studies are conducted with ten 5-year-old preschool children, during which children are asked to evaluate four types of construction play materials and four types of metallophones.In the study, the important design attributes of these two types of play materials preferred by preschool children are analyzed by gathering their own evaluation criteria. Based on the interview data, children&rsquo / s preferences, evaluation criteria and the reasons behind their preferences are tried to be identified. The results of the study show that, children evaluated construction play materials considering method of construction, form of the pieces, color, size, types of pieces, types of constructions, ease of construction and material. Children evaluated metallophones considering color, placement of the keys, sound, being in the openbeing closed, form, size, storage of the mallets, weight, size of the mallets, form of the keys, coding, number of mallets, number of keys, height and material. The study also includes the analysis of the relationships between children&rsquo / s evaluation criteria for each product group and comparison of the evaluation criteria related to construction play materials and metallophones.

The use of perfluorocarbons in encapsulated cell systems: their effect on cell viability and function and their use in noninvasively monitoring the cellular microenvironment

Goh, Fernie 01 April 2011 (has links)
Implantation of tissue engineered pancreatic constructs can provide for a physiologic regulation of blood glucose levels. A major concern in designing such constructs is ensuring sufficient oxygenation of the cells, as oxygen is usually the limiting nutrient affecting cell viability and function. Furthermore, in vivo factors influencing construct oxygenation often lead to implant failure, and are detected primarily on end physiologic effects. The ability of perfluorocarbons (PFCs) to dissolve large amounts of oxygen and their high fluorine content makes these compounds a potentially valuable oxygen delivery tool and good 19F Nuclear Magnetic Resonance (NMR) markers for dissolved oxygen concentration (DO). Experimental studies and simulations showed that although the addition of 10 vol% PFC increased construct oxygenation, this improvement was minimal and had limited benefits on the growth and function of encapsulated bTC-tet cells under normoxic and hypoxic conditions. A dual PFC method that utilizes 19F NMR spectroscopy was developed to noninvasively monitor DO within a tissue construct and in its surroundings. In vitro studies using an NMR-compatible bioreactor demonstrated the feasibility of this method to monitor the DO within alginate beads containing metabolically active bTC-tet cells, relative to the DO in the culture medium, under perfusion and static conditions. In vivo, the method was capable of acquiring real-time DO measurements in murine models. Measured DO can be correlated with the physiological state of the implant examined post-explantation and was compatible with the therapeutic function of the implant.
