In the last few years, several organizations have been looking for strategies to meet the needs of users of Information Technology (IT). The decentralization of IT and the empowerment of nonprofessional users have been a viable option among these strategies. This study aimed to identify the End-User Development (EUD) strategies adopted by organizations. A systematic mapping was performed in order to provide for a structured body of knowledge and find potential research gaps. The results show that EUD methods and techniques are the most common strategies addressed in the literature. Also, most of the EUD strategies identified a focus either on EUD managerial issues, such as risk management, or on more technical elements, such as the implementation of components for EUD applications. The benefits and barriers to the adoption of EUD by organizations are also presented in this study. In general, defining EUD processes is a common gap in EUD surveys. We reinforce the need to carry out more research on the adoption of EUD in organizations, with a high level of evidence to validate the results.

Electronic Service Quality (e-SQ) is a topic that has been reviewed by several authors and, given the situation we live in, has become more relevant in the world; therefore, it is of vital importance to generate an effective measurement of the service being provided, which will allow companies to know the needs and expectations of their customers and how they evaluate the service received. This article considers an exploratory-descriptive research, which through a systematic literature mapping (MSL) reviews the methods and techniques that have been applied for the validity of the scales derived from e-SQ, thus generating a focused view of the methods applied in scientific research in the last five years. With the results obtained, a theoretical model for validating a scale is generated and proposed, which could be useful for researchers seeking to confirm and validate their scales or who are in the process of developing a research project.

State Of Affairs

Purpose The business intelligence (BI) literature is in a flux, yet the knowledge about its varying theoretical roots remains elusive. This state of affairs draws from two different scientific communities (informatics and business) that have generated multiple research streams, which duplicate research, neglect each other’s contributions and overlook important research gaps. In response, the authors structure the BI scientific landscape and map its evolution to offer scholars a clear view of where research on BI stands and the way forward. For this endeavor, the authors systematically review articles published in top-tier ABS journals and identify 120 articles covering 35 years of scientific research on BI. The authors then run a co-citation analysis of selected articles and their reference lists. This yields the structuring of BI scholarly community around six research clusters: environmental scanning (ES), competitive intelligence (CI), market intelligence (MI), decision support (DS), analytical technologies (AT) and analytical capabilities (AC). The co-citation network exposed overlapping and divergent theoretical roots across the six clusters and permitted mapping the evolution of BI research following two pendulum swings. This study aims to contribute by structuring the theoretical landscape of BI research, deciphering the theoretical roots of BI literature, mapping the evolution of BI scholarly community and suggesting an agenda for future research. Design/methodology/approach This paper follows a systematic methodology to isolate peer-reviewed papers on BI published in top-tier ABS journals. Findings The authors present the structuring of BI scholarly community around six research clusters: ES, CI, MI, DS, AT and AC. The authors also expose overlapping and divergent theoretical roots across the six clusters and map the evolution of BI following two pendulum swings. In light of the structure and evolution of the BI research, the authors offer a future research agenda for BI research. Originality/value This study contributes by elucidating the theoretical underpinnings of the BI literature and shedding light upon the evolution, the contributions, and the research gaps for each of the six clusters composing the BI body of knowledge.

SummaryWe evaluated the evidence in support of the suggestion that the risk of deep vein thrombosis after hip surgery is lower with regional than with general anesthesia. A literature search was performed to retrieve all articles which reported on the incidence of postoperative thrombosis in both fractured and elective hip surgery. Articles were included if the method of anesthesia used was reported and if they used mandatory venography. Based upon the quality of study design the level of evidence provided by a study was graded.In patients who did not receive prophylaxis there were high level studies in elective and fractured hip surgery. All studies showed a statistically significantly lower incidence of postoperative deep vein thrombosis with regional anesthesia (relative risk reductions of 46-55%). There were no direct comparative studies in patients who received prophylaxis. However, between study comparisons did not show even a trend towards to lower incidence of postoperative thrombosis with regional anesthesia.

Aim/Purpose: This paper presents a study of Virtual Communities of Practice (VCoP) evaluation methods that aims to identify their current status and impact on knowledge sharing. The purposes of the study are as follows: (i) to identify trends and research gaps in VCoP evaluation methods; and, (ii) to assist researchers to position new research activities in this domain. Background: VCoP have become a popular knowledge sharing mechanism for both individuals and organizations. Their evaluation process is complex; however, it is recognized as an essential means to provide evidences of community effectiveness. Moreover, VCoP have introduced additional features to face to face Communities of Practice (CoP) that need to be taken into account in evaluation processes, such as geographical dispersion. The fact that VCoP rely on Information and Communication Technologies (ICT) to execute their practices as well as storing artifacts virtually makes more consistent data analysis possible; thus, the evaluation process can apply automatic data gathering and analysis. Methodology: A systematic mapping study, based on five research questions, was carried out in order to analyze existing studies about VCoP evaluation methods and frameworks. The mapping included searching five research databases resulting in the selection of 1,417 papers over which a formal analysis process was applied. This process led to the preliminary selection of 39 primary studies for complete reading. After reading them, we select 28 relevant primary studies from which data was extracted and synthesized to answer the proposed research questions. Contribution: The authors of the primary studies analyzed along this systematic mapping propose a set of methods and strategies for evaluating VCoP, such as frameworks, processes and maturity models. Our main contribution is the identification of some research gaps present in the body of studies, in order to stimulate projects that can improve VCoP evaluation methods and support its important role in social learning. Findings: The systematic mapping led to the conclusion that most of the approaches for VCoP evaluation do not consider the combination of data structured and unstructured metrics. In addition, there is a lack of guidelines to support community operators’ actions based on evaluation metrics.

Abstract Background Wrist arthrolysis is a viable option in wrist stiffness and can be performed via open or arthroscopic techniques. Purpose The aim of the study is to describe and evaluate the available techniques of open and arthroscopic arthrolysis of the radiocarpal joint and the distal radio ulnar joint (DRUJ) in posttraumatic wrist stiffness. Methods A systematic literature search was performed in PubMed to identify studies reporting on open and arthroscopic wrist arthrolysis. Key words included “open wrist arthrolysis,” “arthroscopic wrist arthrolysis,” “post-traumatic wrist stiffness,” and “DRUJ arthrolysis.” Data were extracted independently by a pair of reviewers. Results Overall, 637 studies were identified; 13 additional articles were found through previous publications (total 650 articles). A total of 612 records resulted after duplicates was removed. Fourteen studies were selected and only eight respected the inclusions criteria. One study focused on volar open arthrolysis and four studies on arthroscopic arthrolysis of the radiocarpal joint; two studies reported on open arthrolysis and two studies on arthroscopic DRUJ arthrolysis. Range of motion following open and arthroscopic wrist arthrolysis improved in all studies. Conclusion Both arthroscopic and open arthrolysis can lead to similar and satisfactory results in radiocarpal joint and DRUJ stiffness.. Level of Evidence This is a level 3a study.

Background: High-level athletes (HLAs) have been shown to have better short-term outcomes than nonathletes (NAs) after hip arthroscopy. Purpose: (1) To report midterm outcomes of HLAs after primary hip arthroscopy and (2) to compare their results with a propensity-matched cohort of NA patients. Study Design: Cohort study; Level of evidence, 3. Methods: Data were prospectively collected and retrospectively reviewed between February 2008 and November 2015 for HLAs (professional, college, or high school) who underwent primary hip arthroscopy in the setting of femoroacetabular impingement syndrome (FAIS). HLAs were included if they had preoperative, minimum 2-year, and minimum 5-year follow-up data for the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), and Hip Outcome Score Sports-Specific Subscale (HOS-SSS). Radiographic and intraoperative findings, surgical procedures, patient-reported outcomes (PROs), patient acceptable symptomatic state (PASS), minimal clinically important difference (MCID), and return to sport were reported. The HLA study group was propensity-matched to a control group of NA patients for comparison. Results: A total 65 HLA patients (67 hips) were included in the final analysis with mean follow-up time of 74.6 ± 16.7 months. HLAs showed significant improvement in all PROs recorded, achieved high rates of MCID and PASS for mHHS (74.6% and 79.4%, respectively) and HOS-SSS (67.7% and 66.1%, respectively), and returned to sport at high rates (80.4%). When compared with the propensity-matched NA control group, HLAs reported higher baseline but comparable postoperative scores for the mHHS and NAHS. HLA patients achieved MCID and PASS for mHHS at similar rates as NA patients, but the HLA patients achieved PASS for HOS-SSS at higher rates that trended toward statistical significance (66.1% vs 48.4%; P = .07). NA patients underwent revision arthroscopic surgery at similar rates as HLA patients (14.9% vs 9.0%, respectively; P = .424). Conclusion: Primary hip arthroscopy results in favorable midterm outcomes in HLAs. When compared with a propensity-matched NA control group, HLAs demonstrated a tendency toward higher rates of achieving PASS for HOS-SSS but similar arthroscopic revision rates at minimum 5-year follow-up.

Category: Other Introduction/Purpose: Hallux rigidus is one of the most common pathologies afflicting the foot. Various joint salvage techniques have been described with a multitude of different implants. Recently, a synthetic cartilage implant composed of polyvinyl alcohol (PVA) received FDA premarket approval for treatment of arthritis of the great toe and has been used in over 4,000 cases. The purpose of this study was to systematically review the clinical evidence supporting the use of a PVA implant in hallux rigidus. Methods: A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Using the terms “cartiva OR polyvinyl alcohol OR synthetic cartilage OR hemiarthroplasty AND hallux rigidus OR great toe arthritis OR first toe arthritis “ we searched the PubMed/Medline database in December 2017. In addition, the reference list of publications were scanned for further relevant studies. Results: 4 studies met the inclusion criteria, all of which were derived from a single randomized controlled trial. At short-term follow-up (2 years), patients undergoing placement of a PVA implant had significant improvement in Foot and Ankle Ability Measure (FAAM) sports and activity of daily living, as well as VAS pain scores. The outcomes of the surgery were found to be noninferior compared to arthrodesis. At intermediate follow-up (5 years), the improvement in clinical outcomes persisted and implant survivorship was 96%. Conclusion: There are limited studies available detailing the outcomes of a PVA implant for hallux rigidus, however the results that are available demonstrate a high level of evidence. There are no long-term publications assessing the outcomes of a PVA implant for hallux rigidus.

Geotechnical complexity in mining often leads to geotechnical uncertainty which impacts both safety and productivity. However, as mining progresses, particularly for strip mining operations, a body of knowledge is acquired which reduces this uncertainty and can potentially be used by mining engineers to improve the prediction of future mining conditions. In this paper, we describe a new method to support this approach based on modelling and neural networks. A high-level causal model of the mining operations based on historical data for a number of parameters was constructed which accounted for parameter interactions, including hydrogeological conditions, weather, and prior operations. An artificial neural network was then trained on this historical data, including production data. The network can then be used to predict future production based on presently observed mining conditions as mining proceeds and compared with the model predictions. Agreement with the predictions indicates confidence that the neural network predictions are properly supported by the newly available data. The efficacy of this approach is demonstrated using semi-synthetic data based on an actual mine.

ABSTRACT Introduction: Sports injury is an important reason to interfere with sports training and physical exercise since it will not only bring unnecessary pain to the injured body, but also bring out negative emotions in athletes. Objective: To study the sports injury characteristics of high level competitive aerobics athletes in China. Methods: Literature data, questionnaire survey, expert interviews, field observation, mathematical statistics and physiotherapy tracking were used. Results: Wrists, ankles, waist and knees were the most frequently injured parts in high level competitive aerobics athletes in China. The main type of injury was acute injury, but chronic injury (48.18%) could not be ignored. Ninety percent of active high-level competitive aerobics athletes train with injuries, and 10 percent of them completely stop training because of injuries. Conclusions: Athletes should pay attention to their physical reserve and strengthen physical training. They must also be attentive to self-supervision, their own subjective feelings, and control the amount of exercise done. Level of evidence II; Therapeutic studies - investigation of treatment results.
