Factors impacting knowledge transfer success in information systems outsourcing

Despite increased research interest on knowledge transfer in information systems (IS) outsourcing, the field still lacks sound and holistic understanding of the key factors influencing knowledge transfer success. The present paper attempts to provide a synthesis of existing theoretical perspectives and empirical findings related to the factors that facilitate or hamper knowledge transfer success in IS outsourcing. The data collection method is discussed and the key findings are presented. Conclusion is drawn and further research is suggested

Micro-fading spectrometry: investigating the wavelength specificity of fading

A modified microfading spectrometer incorporating a linear variable filter is used to investigate the wavelength dependence of fading of traditional watercolour pigments, dosimeters and fading standards at a higher spectral resolution and/or sampling than had previously been attempted. While the wavelength dependence of photochemical damage was largely found to correlate well with the absorption spectra of each material, exceptions were found in the case of Prussian blue and Prussian green pigments (the latter includes Prussian blue), for which an anti-correlation between the spectral colour change and the absorption spectrum was found

An investigation of knowledge brokering during service encounters

Service encounters present excellent opportunities for obtaining and exchanging so called tacit and explicit knowledge between customers and organisations. Recently, the role of frontline employees as knowledge brokers between organisations and their customers has received attention from scholars and practitioners. Despite the significant role played by frontline employees in obtaining knowledge from customers and sharing it during service encounters, there is a lack of research that provides a comprehensive framework intended to explain their role during such engagements. Following an extensive literature review we developed a research model that identifies (1) the role of frontline employees as knowledge brokers for customers and organisations and (2) the factors that influence their roles as knowledge brokers during service encounters. In total, thirty (30) semi-structured interviews with different informants (i.e. managers and employees) from three top commercial banks in Jordan(X, Y, Z) were administered through three case studies. We adopted a qualitative ‘interpretative’ methodological approach to the analysis of the empirical data. Our findings from an evidence-based analysis suggest that the knowledge brokering engaged in by frontline employees during service encounters is affected by four sets of factors (organisational–level, individual-level, technology-level, and knowledge–level)

An investigation of knowledge transfer in information systems (IS) outsourcing

Inter-organisational knowledge transfer is of central interest both as an academic topic and in business practice. However, despite the attention given to the importance of this subject from different perspectives in various contexts, little is known about how knowledge is transferred from vendors to clients in information systems (IS) outsourcing. This research attempts to address this apparent theoretical and empirical deficiency by providing a deeper understanding and more holistic analysis of the key factors which facilitate or inhibit knowledge transfer success in IS outsourcing. This study employed a qualitative, multiple case study approach in the interpretive paradigm. Data was collected mainly from the IS departments of three public sector organisations in Oman. Oman was chosen as the context for the study due to its rapid growth in recent years and the opportunity to consider the many major IS outsourcing projects which have been undertaken by its public sector. Through semi-structured interviews, this study explored the perspectives of the internal IS staff on their experience of knowledge transfer and learning from vendors through various IS outsourcing projects. Written and electronic documentations as well as non-participant observations also served as important triangulation and complementary sources in understanding the phenomenon being studied and as means of gaining additional perspectives and further insights on key issues. The empirical evidence demonstrated that there are five sets of factors which facilitate or inhibit knowledge transfer success in IS outsourcing. These are: knowledge (knowledge tacitness and knowledge complexity), client (learning intent, absorptive capacity and motivation), vendor (vendor capability, vendor credibility and vendor openness), relationship (relationship quality, relationship duration, relationship governance and organisational distance) and knowledge transfer mechanisms (formal and informal). The findings of this study contributed and extended the growing body of research on IS outsourcing by developing a novel, holistic conceptual framework which examined five sets of factors that impact knowledge transfer success. Additionally, it provided prescriptive value for practitioners seeking to realise efficient and effective knowledge transfer in IS outsourcing.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

Using cases as a teaching tool in IS education

Educators use many methods in their classrooms to aid in teaching. One commonly used method of instruction is the use of cases as a teaching tool in IS education. Cases can allow students to develop high-order reasoning skills, bring real world examples into the classroom, allow students to learn by doing, bring organizational impacts, social values, and ethical issues to the forefront of discussion, and include realistic content, objectives and knowledge transfer. As part of its mission to support Information Systems (IS) education, JISE is pleased to publish this special issue devoted to IS teaching cases. The twelve teaching cases in this issue are divided into five IS areas. These teaching cases may be copied and used by IS faculty for any teaching purposes

The D allele of angiotensin-converting enzyme gene is associated with greater hemodynamic response to resistance exercises

HYPOTHESIS/INTRODUCTION: The association of ACE I/D polymorphism and hemodynamic response to exercise have been limited to primarily aerobic exercises. We hypothesized that D allele carriers would show greater hemodynamic response to resistance exercise, as has been observed with aerobic. This study aimed to investigate the association of ACE I/D polymorphism and hemodynamic (blood pressure (BP), heart rate (HR) and rate-pressure product (RPP)) response to resistance exercise in young healthy subjects.MATERIALS AND METHODS: ACE I/D polymorphisms were studied by PCR analysis from 75 healthy men. Subjects completed a resistance exercise session of three sets of 10 knee extension repetitions with loads of 50, 75 and 100% of 10RM and two-minute rest intervals. Hemodynamic measures were recorded before and immediately after each set. Analysis of variance was used to identify significant differences among ACE genotypes. RESULTS: ACE I/D polymorphism is associated with hemodynamic response to resistance exercise, as healthy subjects with ACE D allele were prone to higher responses. In addition, this phenotypic difference seems to be a load-dependent trend. CONCLUSION: ACE DD carriers exhibit greater heart work during resistance exercise. Future studies should focus on the influence of resistance training period with different workloads on the hemodynamic response in healthy individuals with different ACE genotypes

Prognostic model to predict postoperative acute kidney injury in patients undergoing major gastrointestinal surgery based on a national prospective observational cohort study.

Background: Acute illness, existing co-morbidities and surgical stress response can all contribute to postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. The aim of this study was prospectively to develop a pragmatic prognostic model to stratify patients according to risk of developing AKI after major gastrointestinal surgery. Methods: This prospective multicentre cohort study included consecutive adults undergoing elective or emergency gastrointestinal resection, liver resection or stoma reversal in 2-week blocks over a continuous 3-month period. The primary outcome was the rate of AKI within 7 days of surgery. Bootstrap stability was used to select clinically plausible risk factors into the model. Internal model validation was carried out by bootstrap validation. Results: A total of 4544 patients were included across 173 centres in the UK and Ireland. The overall rate of AKI was 14·2 per cent (646 of 4544) and the 30-day mortality rate was 1·8 per cent (84 of 4544). Stage 1 AKI was significantly associated with 30-day mortality (unadjusted odds ratio 7·61, 95 per cent c.i. 4·49 to 12·90; P < 0·001), with increasing odds of death with each AKI stage. Six variables were selected for inclusion in the prognostic model: age, sex, ASA grade, preoperative estimated glomerular filtration rate, planned open surgery and preoperative use of either an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker. Internal validation demonstrated good model discrimination (c-statistic 0·65). Discussion: Following major gastrointestinal surgery, AKI occurred in one in seven patients. This preoperative prognostic model identified patients at high risk of postoperative AKI. Validation in an independent data set is required to ensure generalizability

Mammalian Kinesin-3 Motors Are Dimeric In Vivo and Move by Processive Motility upon Release of Autoinhibition

Kinesin-3 motors drive the transport of synaptic vesicles and other membrane-bound organelles in neuronal cells. In the absence of cargo, kinesin motors are kept inactive to prevent motility and ATP hydrolysis. Current models state that the Kinesin-3 motor KIF1A is monomeric in the inactive state and that activation results from concentration-driven dimerization on the cargo membrane. To test this model, we have examined the activity and dimerization state of KIF1A. Unexpectedly, we found that both native and expressed proteins are dimeric in the inactive state. Thus, KIF1A motors are not activated by cargo-induced dimerization. Rather, we show that KIF1A motors are autoinhibited by two distinct inhibitory mechanisms, suggesting a simple model for activation of dimeric KIF1A motors by cargo binding. Successive truncations result in monomeric and dimeric motors that can undergo one-dimensional diffusion along the microtubule lattice. However, only dimeric motors undergo ATP-dependent processive motility. Thus, KIF1A may be uniquely suited to use both diffuse and processive motility to drive long-distance transport in neuronal cells
