A systematic review of knowledge management and knowledge sharing: Trends, issues, and challenges

Abstract This study aims to highlight and summarize the possible antecedents and factors that facilitate or impede knowledge management and knowledge sharing in organizations. A meta-review of 64 articles for the years 2010–2015 has been conducted. It includes both quantitative and qualitative studies related to antecedents and barriers to knowledge management and knowledge sharing. Cooperation bias was the most frequent limitation in most studies included in this meta-review as the respondents were likely to over-estimate their participation in knowledge management (KM) and knowledge sharing (KS). Future studies of knowledge management and knowledge sharing can be focused on exploring the same issues in developing countries in different sectors. Relationship of knowledge sharing and transfer can be further explored with social media, organizational politics, and communication in the organizations. The result of meta-review will generate nomothetic knowledge implications by scrutinizing the antecedents and barriers to knowledge sharing and transfer.
Project time–cost trade-off: a Bayesian approach to update project time and cost estimates

Abstract Uncertainties among time and cost items are important to consider because of their immense impacts on the overall performance of any project. In this paper, a project’s cost and time elements are improved by crashing and a Bayesian Belief Network (BBN) model is developed to handle the uncertainties. BBN provides a framework for presenting causal relationships and enables probabilistic inference among a set of variables. The approach used in this paper can explicitly quantify the cost amount and time taken in various circumstances considering all the relevant uncertainties among the elements. The total cost and time of any project can be projected in this approach very effectively with certain probabilities. Sensitivity analysis is also performed to find the most important tasks of the project in terms of cost and time. The capabilities of the proposed approach are explained by an empirical example and the results of the proposed method are compared with those of other popular project management tools.
Walking Control Based on Step Timing Adaptation

Step adjustment can improve the gait robustness of biped robots; however, the adaptation of step timing is often neglected as it gives rise to nonconvex problems when optimized over several footsteps. In this article, we argue that it is not necessary to optimize walking over several steps to ensure gait viability and show that it is sufficient to merely select the next step timing and location. Using this insight, we propose a novel walking pattern generator that optimally selects step location and timing at every control cycle. Our approach is computationally simple compared to standard approaches in the literature, yet guarantees that any viable state will remain viable in the future. We propose a swing foot adaptation strategy and integrate the pattern generator with an inverse dynamics controller that does not explicitly control the center of mass nor the foot center of pressure. This is particularly useful for biped robots with limited control authority over their foot center of pressure, such as robots with point feet or passive ankles. Extensive simulations on a humanoid robot with passive ankles demonstrate the capabilities of the approach in various walking situations, including external pushes and foot slippage, and emphasize the importance of step timing adaptation to stabilize walking.
Effects of Laminate Arrangement on the Failure Behaviour of Hybrid Composite Plates under Transverse Sinusoidal Load

The present work deals with the effects of laminate arrangement on the failure behaviour of hybrid composite plates under transverse sinusoidal load. Failure analysis has been a subject under study for many years, especially for composite materials. This is largely due to the spontaneous nature of composite materials when it fails without warning. Hybrid composite are commonly utilized to improve the unexpected and instantaneous failure mode of composites. Nevertheless, the failure behaviour of hybrid composites is still not well understood. Moreover, studies have not exploited the effects on sinusoidal transverse loading on hybrid composites. Therefore, the first and last ply failure of the hybrid composite laminate was simulated and analysed using built in failure criteria function in ANSYS. The hybrid composite consisted of graphite (GR) and glass (GL), with lamination schemes of [GL/GL/GL/GL], [GL/GL/GL/GR] and [GR/GL/GL/GL] were subjected of transverse sinusoidal loading. The laminate failure was predicted using the Maximum Stress Theory. Prior to determining the first and last ply failure of the hybrid composite plate, numerical validation was conducted to ensure the accuracy of the finite element software. The failure curves of the first ply failure and last ply failure were plotted and the results showed significant difference in the correlation of loadings that caused first and last ply failures and the lamination scheme of the hybrid composite plates. Thus, it can be said that the present work proves to be of importance and valuable in the field of study as well as enriching the knowledge regarding the failure behaviour of hybrid composite plate under transverse sinusoidal load of different laminate arrangement.
Influence of Different Fin Configurations on Small-Signal Performance and Linearity for AlGaN/GaN Fin-HEMTs

In this paper, AlGaN/GaN high-electron mobility transistors (HEMTs) with different fin configurations are fabricated and analyzed. Through S-parameter measurements and modeling of the designed devices, a detailed RF investigation on small-signal model parameters is performed under different biasing conditions. Good agreements between measured and simulated scattering parameters up to 40 GHz illustrate the validity and accuracy of the model. The influence of different fin structures on model parameters and linearity improvement is examined, and this can help to improve the frequency characteristics of fin structure by optimizing the fin length, fin width, and trench width. The significant linearity of Fin-HEMTs is confirmed by the analysis of the model parameters, which is the first time to study the small-signal characteristic of AlGaN/GaN Fin-HEMTs in detail.
Get out of fines free: Recruiting student usability testers via fine waivers

Abstract St. John Fisher College's Lavery Library's Access Services and Systems departments began a pilot project in which students with overdue fines tested usability of library Web sites in exchange for fine waivers. Circulation staff promoted the program and redeemed fine waiver vouchers at the Checkout Desk, while Systems staff administered testing and provided vouchers to participants. Staff evaluated the pilot to be a success, as qualitative data were collected to enable iterative changes to library Web sites, and users had a positive customer service experience. The piloted method may be applied in the future to assess other programs and services.
Development of a Modified Plug-Flow Anaerobic Digester for Biogas Production from Animal Manures

Traditional plug-flow anaerobic reactors (PFRs) are characterized by lacking a mixing system and operating at high total solid concentrations, which limits their applicability for several kinds of manures. This paper studies the performance of a novel modified PFR for the treatment of pig manure, characterized by having an internal sludge mixing system by biogas recirculation in the range of 0.270–0.336 m3 m−3 h−1. The influence on the methane yield of four operating parameters (recirculation rate, hydraulic retention time, organic loading rate, and total solids) was evaluated by running four modified PFRs at the pilot scale in mesophilic conditions. While the previous biodegradability of organic matter by biochemical methane potential tests were between 31% and 47% with a methane yield between 125 and 184 LCH4 kgVS−1, the PFRs showed a suitable performance with organic matter degradation between 25% and 51% and a methane yield of up to 374 LCH4 kgVS−1. Operational problems such as solid stratification, foaming, or scum generation were avoided.
Closed-Form Analysis of Metastability Voltage in 28-nm UTBB FD-SOI CMOS Technology

In this brief, analytical expressions for the metastability voltage of latch-type comparators at sub-threshold operation are advanced. Drain induced barrier lowering (DIBL) and body bias effects are investigated in order to achieve an appropriate model for fully depleted silicon-on-insulator (FD-SOI) CMOS technology. Since, metastability voltage variations have been widely studied as the major cause of latch input offset, statistical expressions are also derived to estimate the yield of latch-type comparators. The analytical results show close agreement with extensive HSPICE simulations using a 28-nm ultra-thin body and buried oxide (UTBB) FD-SOI CMOS technology.
Comparative Evaluation of Compacting Process for Base Materials using Lab Compaction Methods

Precise characterization of the compactability of aggregates and soils in the laboratory has always been a challenge to pavement technologists. The present study investigated compactability of aggregates and soils through the comparison of three laboratory compaction methods, the Superpave Gyratory Compactor, the Marshall impacting hammer, and a vibratory compacting machine. Accelerometers were attached to the Marshall impacting hammer and a laboratory scale vibratory compactor to capture the dynamic response of soils and aggregates during compaction. The results from this comparative experiment indicated that there was a consistent relationship between the stiffness of soils and aggregates and the dynamic responses from impaction and vibration, which can be used to better characterize the compactability of different paving materials through laboratory testing.
Study on the Connection Between the Set Transient in RRAMs and the Progressive Breakdown of Thin Oxides

In this paper, the transition rate (TR) from the high-resistance state to the low-resistance state of a HfO2-based resistive random access memory (RRAM) is investigated. The TR is statistically characterized by applying constant voltage stresses in the range from 0.45 to 0.65 V. It is found that TR follows a voltage dependence which closely resembles the one exhibited by metal-insulator-semiconductor / metal-insulator-metal structures when subjected to constant voltage stress, but with remarkably different fitting parameters. This result suggests a common underlying mechanism in both evolutionary behaviors. Furthermore, the investigation provides additional evidence supporting the micro-structural changes in the oxide after the forming step as well as the role played by the atomic species during the SET event.

Current Control of a Seven-Level Voltage Source Inverter

Demanding higher power, higher power quality, lower switching loss, and eliminating interface transformers in industrial applications caused significant attention toward multilevel converters. This paper presents current control of a seven-level topology for medium-voltage high-power applications. This topology has fewer active switches and components, and less control complexity in comparison to the other existing classic and advanced seven-level topologies. A comprehensive review has been done on seven-level topologies to demonstrate the advantages of this topology in this paper. A control method based on model predictive control (MPC) is developed to balance the flying capacitors of this topology at their desired values and control the output currents without the need of pulsewidth modulation blocks, and proportional-integral (PI) controllers, which is the advantage of MPC in power electronics applications. In order to evaluate the performance of the seven-level topology and the developed control method effectiveness, experimental results are shown for different conditions, which demonstrate the feasibility of the seven-level topology and the developed control technique.
Experiment on the Breakup of Liquid Jets in Different Cross-Airflows

The experiment is conducted with a high-speed camera to investigate the breakup processes of liquid jets in uniform, shear-laden, and swirling cross-airflows. The liquid used in the test is water, the nozzle diameter is 2 mm, and the liquid-to-air momentum flux ratio q ranges from 5 to 3408.5. The results indicate that liquid jets break up to form small droplets in the uniform cross-airflow. There is an exponential relation between the broken position and q. In the shear-laden cross-airflow, the penetration depth of the jet is similar to that of the uniform case, both of which increase with the increase of q. When q and the mean Weber number are the same as the uniform case, the penetration depth of the jet increases by 25% when the velocity ratio of the upper and lower inlets is UR=5; the jet penetration depth decreases by 47.2% when the ratio of UR=0.2 and the jet breaks up quickly and the atomization effect will be better. In the swirling cross-airflow, the jet trajectory is similar to the uniform case and also satisfies the exponential property. When the swirl is weak (swirling number SN=0.49), the jet penetration depth increases compared to the uniform case; when the swirl is strong (SN=0.82), the cross-swirling airflow restrains the jet penetration depth.
Corporate governance and earnings management: An Australian perspective

This study examines the extent to which the first-time adoption of the Australian Stock Exchange (ASX) Corporate Governance Council‟s corporate governance principles and recommendations was associated with lower levels of earnings management. Cross-sectional results indicate that the existence of an audit committee was associated with lower levels of earnings management in pre-, but not post-, recommendations. Lower director ownership was associated with higher levels of earnings management pre-, but not post-, recommendations. On the other hand, the existence of a remuneration committee was associated with lower levels of earnings management preand postrecommendations. In addition, longitudinal analysis shows that, following the first-time adoption, the only governance mechanism associated with reductions in earnings management was the establishment of a remuneration committee.
Using an Interactive Online Quiz to Recalibrate College Students’ Attitudes and Behavioral Intentions About Phishing

Despite improved spam filtering technology, phishing continues to be a prevalent threat for college students. The current study found that approximately 4-in-10 of the students surveyed (N = 462) indicate they do not know what phishing is and the threat it poses. Students also report initially overestimating their confidence to successfully recognize phishing attempts, and underestimating their susceptibility to being the victim of an attack. By completing an interactive online phishing quiz, which explained what to look for in both counterfeit and legitimate email messages, students’ self-efficacy to identify phishing attempts increased, as did their perceived susceptibility to phishing attacks, their perceptions of the severity of phishing, their intentions to learn more about the topic, and their intentions to discuss phishing with others. These results indicate that a simple, interactive online phishing quiz could be used as an effective teaching tool to supplement existing educational attempts regarding phishing on college campuses.
Consumers’ values and behaviour in the Brazilian coffee-in-capsules market: promoting circular economy

Coffee consumption is changing. Monodose, flavoured coffee capsules provide new experiences beyond the traditional custom of brewing coffee. These pods allow access to a selection of premium coffee worldwide but create huge quantities of plastic-aluminium packaging waste. The paper examines the novelty of coffee capsule consumption in Brazil in terms of consumers’ perspectives about ethical enterprise and environmental stewardship. We argue for ‘waste to resource’ management and applying reverse logistics to the coffee production supply chain. Based on circular economy principles and fuelled by the ‘green’ awareness of Brazilian coffee consumers, we propose a conceptual framework to support business decision-making by adopting a systemic intervention from the consumer viewpoint. To structure the situation, we conducted over 40 interviews, using purposive sampling. Analytic hierarchy process, value focused thinking and Rich Picture technique informed our problem structuring approach. Findings illustrate that reverse logistics supply chain in coffee capsule manufacturing presents real challenges to achieving circular practice. Yet, the eco-values of Brazilian coffee enthusiasts may be partly considered a ‘wealth of information flow’ and a potential driving force for change. This paper should be of interest to researchers/practitioners exploring how consumers may contribute to behavioural change, towards more circular business.
Artificial Intelligence in FinTech: understanding robo-advisors adoption among customers

Purpose Considering the increasing impact of Artificial Intelligence (AI) on financial technology (FinTech), the purpose of this paper is to propose a research framework to better understand robo-advisor adoption by a wide range of potential customers. It also predicts that personal and sociodemographic variables (familiarity with robots, age, gender and country) moderate the main relationships. Design/methodology/approach Data from a web survey of 765 North American, British and Portuguese potential users of robo-advisor services confirm the validity of the measurement scales and provide the input for structural equation modeling and multisample analyses of the hypotheses. Findings Consumers’ attitudes toward robo-advisors, together with mass media and interpersonal subjective norms, are found to be the key determinants of adoption. The influences of perceived usefulness and attitude are slightly higher for users with a higher level of familiarity with robots; in turn, subjective norms are significantly more relevant for users with a lower familiarity and for customers from Anglo-Saxon countries. Practical implications Banks and other firms in the finance industry should design robo-advisors to be used by a wide spectrum of consumers. Marketing tactics applied should consider the customer’s level of familiarity with robots. Originality/value This research identifies the key drivers of robo-advisor adoption and the moderating effect of personal and sociodemographic variables. It contributes to understanding consumers’ perceptions regarding the introduction of AI in FinTech.

CROP LOAD REGULATION WITH CHEMICAL THINNERS IN DEVECI PEAR (PYRUS COMMUNIS L.)

The efficacy of three different doses of ammonium thiosulfate (ATS), potassium thiosulfate (KTS) and BA (6-benzyladenine) on fruit quality, yield and return bloom was evaluated in this present experiment on ‘Deveci’ pear (Pyrus communis, L.). All treatments were compared to an unsprayed control and hand fruit thinning. The highest fruit set was achieved with BA treatments. It was significantly reduced in KTS rates compared to control and other thinning treatments. KTS sprays create a statistically significant increase in fruit diameter and fruit weight, while ATS and BA have had no dramatic effect. Hand fruit thinning has resulted in heavier fruit at harvest similar to KTS with 2%. Thinners increased the percentage of fruit to 75 mm in diameter and proportions to 250-500 g fruit weight. In the control trees, the ratio of fruit to 75 mm diameter was 57%, the 75% or more of which was in hand thinning and chemical thinners. The proportion of fruits within 250-500 g fruit weight group was found in the highest KTS doses. No physiological disorder as bitter pit, water core, and aging disorder and phytotoxicity were observed in fruit samples. Study results show that 2% KTS significantly reduce crop load and increased fruit quality in ‘Deveci’ pear. Therefore, it can be used as an alternative to hand fruit thinning in the ‘Deveci’ pear to achieve high fruit quality. But, neither flower nor fruit thinners induced return bloom in ‘Deveci’ pear.
Public Libraries and the Opioid Crisis, Part 2: Community-Centered Responses

ABSTRACT Numerous articles from major national newspapers have covered the fact that as the opioid crisis has become a pervasive problem in the United States, overdoses in public libraries have become a somewhat common occurrence. Many of these discussions center on librarians being trained to use the overdose reversal drug Naloxone, and that was the primary focus of the first part of this two-part study. However, this second article discusses what libraries are doing to mitigate the impacts of the crisis and help persons from vulnerable populations before matters escalate to become emergency situations. The authors document how libraries are attempting to educate their communities about the opioid crisis, ways they have partnered with community organizations to help opioid dependent persons, and how they have addressed various facilities and security concerns for their buildings.
