An Integrated Framework for Effective Tacit Knowledge Transfer

Effective tacit knowledge transfer is very critical for organizations. However, despite concerted efforts, many organizationsare finding it increasingly difficult to manage tacit knowledge transfer. This paper examines the characteristics of tacitknowledge and develops an integrated framework grounded in knowledge creation theory, social cognitive theory and mediarichness theory for transferring tacit knowledge effectively. The appropriateness and relevance of various knowledge transfermechanisms and the communication media types for different degrees of tacitness is discussed. This framework can guideorganizations in developing well suited knowledge transfer mechanisms to attain optimal tacit knowledge transfer

The Perceived Advantage of Agile Development Methodologies By Software Professionals: Testing an Innovation-Theoretic Model

Proponents of agile processes claim that agile practices result in higher quality software while allowing the flexibility to respond to evolving user requirements. Yet, to the best of our knowledge, no empirical study has really confirmed that benefits accrue to those who use agile processes. Grounded in the agility and diffusion of innovations literature, this research introduces a measure of process agility within the software development domain and relates it to constructs previously employed in the innovation literature. For agile methods, our study has provided empirical support for the proposal that agile development methods lead to developers’ beliefs that they are less complex, more compatible and provide increased benefits. Since developers believe that agility leads to increased benefits, they will be more likely to accept agile methods. For practitioners, this study provides valuable insights into the underlying factors that influence a developer’s beliefs about agile methods

BUSINESS PROCESS REDESIGN AND INFORMATION ARCHITECTURE: ESTABLISHING THE MISSING LINKS

Business Process Redesign (BPR) and Information Architecture (IA) have been recognized as high organizational priority agenda items in the 1990s. This paper provides tile premise for integrating these two critical issues. A model depicting the relationship between IA and BPR is presented. IA design and BPR share a common focus on business processes and, when properly conducted, IA design should produce a stable information architecture capable of supporting existing as well as improved business processes. Furthermore, selected IA methods and techniques are recommended for possible application in BPR. Future research is suggested concerning the need to validate this BPR and IA relationship and test the appropriateness of applying IA methodologies to BPR

Investigating the Role of Information Technology in Building Buyer-Supplier Relationships

A widely held position observed through the lens of transaction cost theory (TCT) has been the role of information technology in decreasing transaction costs between buyers and suppliers and in creating more market based governance structures. However, observations have not supported this contention. In particular, buyer-supplier dyads often engage in cooperative behavior that could offset opportunistic tendencies espoused by TCT. The role of IT in this structure is unclear. This paper examines the relationship between perceived transaction costs and the concept of relationalism within buyer-supplier dyads. The role of IT in mediating this relationship is also examined. Survey data from 203 buyers in the OEM electronics industry is used to test proposed hypotheses. All major constructs, transaction costs, relationalism, and IT use are operationalized using validated multidimensional scales. The results suggest a positive role of IT in partially offsetting the negative relationship between transaction costs and relationalism. The results suggest that the decision to use IT within the dyad can encourage a commitment to establishing relational behavior

Technology Architecture: Examining a Data Driven Model

The 1990s has been marked by the widespread transfer of new information technologies that can alter the fundamental nature of computing. Effective storage and multitasking processing technologies have combined with developments in telecommunications to create new opportunities for resource sharing and communication among computers. The importance of this revolution has been recognized by senior information systems executives, whom have identified the planning and development of corporate information technology structure (architecture) as the most critical issue of the decade (Niederman , Brancheau & Wetherbe, 91). This study, through the responses of 313 North American senior IS executives, will explore the nature of IT (information technology) structure and its relationship to organizational structure

Search for the Lepton-Number-Violating Decay Ξ−→pμ−μ−\Xi^- \to p \mu^- \mu^-

A sensitive search for the lepton-number-violating decay $\Xi^-\to p \mu^-\mu^-$ has been performed using a sample of $\sim10^9$ $\Xi^-$ hyperons produced in 800 GeV/$c$ $p$-Cu collisions. We obtain $\mathcal{B}(\Xi^-\to p \mu^-\mu^-)< 4.0\times 10^{-8}$ at 90% confidence, improving on the best previous limit by four orders of magnitude.Comment: 9 pages, 5 figures, to be published in Phys.

Different Types and Acceptability of Psychotherapies for Acute Anxiety Disorders in Children and Adolescents: A Network Meta-analysis

Importance: Anxiety disorders are common in children and adolescents, and uncertainty remains regarding the optimal strategy of psychotherapies in this population. Objective: To compare and rank the different types of psychotherapies and the different ways of delivering psychological treatments for anxiety disorders in children and adolescents. Data Sources: PubMed, Cochrane Central Register of Controlled Trials, EMBASE, PsycINFO, Web of Science, CINAHL (Cumulative Index to Nursing and Allied Health Literature), ProQuest Dissertations, LILACS (Literatura Latino Americana em Ciências da Saúde), international trial registers, and US Food and Drug Administration reports were searched from inception to November 30, 2017. Study Selection: Randomized clinical trials that compared any structured psychotherapy with another psychotherapy or a control condition for anxiety disorders in children and adolescents were selected. Data Extraction and Synthesis: Four researchers independently performed data extraction and quality assessment. Pairwise meta-analyses and Bayesian network meta-analysis within the random-effects model were used to synthesize data. Main Outcomes and Measures: Efficacy (change in anxiety symptoms) posttreatment and at follow-up, acceptability (all-cause discontinuation), and quality of life and functional improvement were measured. The certainty of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation framework. Results: A total of 101 unique trials including 6625 unique participants compared 11 different psychotherapies with 4 specific control conditions. The certainty of evidence was rated as low or very low for most comparisons. For efficacy, most psychotherapies were significantly more effective than the wait list condition posttreatment (standardized mean difference [SMD], -1.43 to -0.61) and at the longest follow-up (SMD, -1.84 to -1.64). However, only group cognitive behavioral therapy (CBT) was significantly more effective than the other psychotherapies and all control conditions posttreatment. For acceptability, bibliotherapy CBT had significantly more all-cause discontinuations than some psychotherapies and control conditions (range of odds ratios, 2.48-9.32). In terms of quality of life and functional improvement, CBT (delivered in different ways) was significantly beneficial compared with psychological placebo and the wait list condition (SMDs, 0.73 to 1.99). Conclusions and Relevance: Group CBT would be the more appropriate choice of psychotherapy for anxiety disorders in children and adolescents, based on these findings. Other types of psychotherapies and different ways of delivering psychological treatment can be alternative options. Further research is needed to explore specific anxiety disorders, disorder-specific psychotherapy, and moderators of treatment effect

Measurement of the Alpha Asymmetry Parameter for the Omega- to Lambda K- Decay

We have measured the alpha parameter of the Omega- to Lambda K- decay using data collected with the HyperCP spectrometer during the 1997 fixed-target run at Fermilab. Analyzing a sample of 0.96 million Omega- to Lambda K^-, Lambda to p pi- decays, we obtain alpha_Omega*alpha_Lambda = [1.33+/-0.33(stat)+/-0.52(syst)] x 10^{-2}. With the accepted value of alpha_Lambda, alpha_Omega is found to be [2.07+/-0.51(stat)+/-0.81(syst)] x 10^{-2}.Comment: 5 pages, 4 figures, to be appeared as a Rapid Communication in Phys. Rev.

HyperCP: A high-rate spectrometer for the study of charged hyperon and kaon decays

The HyperCP experiment (Fermilab E871) was designed to search for rare phenomena in the decays of charged strange particles, in particular CP violation in $\Xi$ and $\Lambda$ hyperon decays with a sensitivity of $10^{-4}$. Intense charged secondary beams were produced by 800 GeV/c protons and momentum-selected by a magnetic channel. Decay products were detected in a large-acceptance, high-rate magnetic spectrometer using multiwire proportional chambers, trigger hodoscopes, a hadronic calorimeter, and a muon-detection system. Nearly identical acceptances and efficiencies for hyperons and antihyperons decaying within an evacuated volume were achieved by reversing the polarities of the channel and spectrometer magnets. A high-rate data-acquisition system enabled 231 billion events to be recorded in twelve months of data-taking.Comment: 107 pages, 45 Postscript figures, 14 tables, Elsevier LaTeX, submitted to Nucl.
