Design and implementation of a single-phase buck-type inverter via an efficient hybrid control technique
Authors: Yalcin Faruk , Arifoglu Ugur , Yazici Irfan 
Published: May 2022

Purpose
This paper aims to present the design and implementation of a new general-purpose single-phase buck-type inverter.

Design/methodology/approach
The operation of the proposed inverter is based on the general-purpose buck converter. The proposed buck-type inverter topology is designed with reduced numbers of passive and active elements to minimize design cost and complexity. Also, an efficient hybrid control technique based on the proportional‐integral‐derivative (PID) supported by open-loop control signal is offered for the control of the proposed inverter. The proposed hybrid control method improves the performance of the PID controller during the change of inverter operation parameters. A close to single-phase sine wave output voltage with low total harmonic distortion (THD) can be produced by the proposed inverter in a wide range of voltage and frequency lower than the inverter input voltage value.

Findings
Simulation and experimental test studies are applied to the proposed inverter. The experimental laboratory setup is built for 0–50 Hz, 0–100 Vp, 0.5 kW. Both the simulation and the experimental test results show that the single-phase inverter can produce close to sine wave output voltage with THD level under 5% in a wide range of frequency for various operating conditions and for different loads.

Originality/value
In this paper, a new topology and a new hybrid control technique that are patented by the corresponding author are implemented for a single-phase buck-type inverter through a scientific project. The operating results of the study reveal the efficient operating capability with a simple topology structure.

Authors: Stylios Ioannis , Skalkos Andreas , Kokolakis Spyros , Karyda Maria 
Published: May 2022

Purpose
This research aims to build a system that will continuously. This paper is an extended version of SECPRE 2021 paper and presents a research on the development and validation of a behavioral biometrics continuous authentication (BBCA) system that is based on users keystroke dynamics and touch gestures on mobile devices. This paper aims to build a system that will continuously authenticate the user of a smartphone.

Design/methodology/approach
Session authentication schemes establish the identity of the user only at the beginning of the session, so they are vulnerable to attacks that tamper with communications after the establishment of the authenticated session. Moreover, smartphones themselves are used as authentication means, especially in two-factor authentication schemes, which are often required by several services. Whether the smartphone is in the hands of the legitimate user constitutes a great concern and correspondingly whether the legitimate user is the one who uses the services. In response to these concerns, BBCA technologies have been proposed on a large corpus of literature. This paper presents a research on the development and validation of a BBCA system (named BioPrivacy), which is based on the user’s keystroke dynamics and touch gestures, using a multi-layer perceptron (MLP). Also, this paper introduces a new BB collection tool and proposes a methodology for the selection of an appropriate set of BB.

Findings
The system achieved the best results for keystroke dynamics which are 97.18% accuracy, 0.02% equal error rate, 97.2% true acceptance rate and 0.02% false acceptance rate.

Originality/value
This paper develops a new BB collection tool, named BioPrivacy, by which behavioral data of users on mobile devices can be collected. This paper proposes a methodology for the selection of an appropriate set of BB. This paper presents the development of a BBCA system based on MLP.
Investigating the determinants of medical crowdfunding performance: a signaling theory perspective
Authors: Chen Yuangao , Zhou Shasha , Jin Wangyan , Chen Shenqing 
Published: May 2022

PurposeThis study examines the determinants of medical crowdfunding performance. Drawing on signaling theory, the authors investigate how funding-related signals (funding goal and duration), story-related signals (text length, text sentiment, and use of first-person pronouns), and donor-related signals (donor identity disclosure) affect medical crowdfunding performance.Design/methodology/approachThis study analyzed the data of 754 medical crowdfunding projects collected from the Qingsongchou platform in China to test the proposed model.FindingsThe empirical findings reveal that both funding goal and funding duration exhibit a U-shaped relationship with crowdfunding performance. Additionally, the authors find evidence that story text length and donor identity disclosure are positively related to crowdfunding performance, whereas the use of first-person pronouns is negatively related to crowdfunding performance.Originality/valueThis study extends the understanding of the determinants of medical crowdfunding performance through the signaling theory. Specifically, this study provides new insights into the roles of funding goal and funding duration in predicting medical crowdfunding performance and identifies several new predictors of crowdfunding performance, including the use of first-person pronouns in project story text and donor identity disclosure.
Transformational leadership practices of nurse managers: the effects on the organizational commitment and job satisfaction of staff nurses
Authors: Uslu Sahan Fatma , Terzioglu Fusun 
Published: May 2022

Purpose
This study aims to investigate the perception of nurse managers and staff nurses regarding the transformational leadership (TL) style of nurse managers and determine the effects of the TL practices on organizational commitment and job satisfaction of staff nurses.

Design/methodology/approach
This cross-sectional and descriptive study was conducted with 153 nurses (17 nurse managers and 136 staff nurses) working in a university hospital. Data were collected from participants through a demographic questionnaire, leadership practices inventory (self/observer), organizational commitment scale and job satisfaction scale.

Findings
The self-assessment of the TL practices of the nurse managers were more favourable than the assessment of the leadership practices made by staff nurses. The TL practices of the nurse managers accounted for 9% of the total organizational commitment and 24% of the total job satisfaction of the staff nurses.

Originality/value
The results indicated that leadership practices by nurse managers need to show greater awareness of the effects of these leadership practices on the organizational commitment and job satisfaction of their staff nurses. Hospitals need to consider how they develop, support and encourage because of the positive impact TL has on health priorities and retention of staff.
Responsible managing as educational practice
Authors: Bispo Marcelo de Souza 
Published: May 2022

Purpose
This study aims to theoretically introduce the notion of responsible managing as educational practice (RMEP).

Design/methodology/approach
The study is an essay. Traditionally assumed as individual-driven, rational, neutral and unproblematic, the author alternatively considers management not as managerialism but as a social practice that needs to be responsible.

Findings
The author posits that responsible management involves educational experiences enacted through practical wisdom. In this context, education herein is understood not as a scholastic practice taught in business schools or offered within professional training, but that may occur in informal contexts such as managing.

Originality/value
RMEP may contribute to a better comprehension of responsible management in practice. The author draws on the epistemology of practices and the notion of phronesis to support his thesis – that managing can be responsible when assumed as an educative practice performed through practical wisdom and people’s mutual education.
Assessing the correlates of CALEA accreditation: a state-of-the-art review
Authors: Abner Gordon , Rush Sarah 
Published: May 2022

PurposeThe purpose of this study is to synthesize empirical research on the correlates of Commission on Accreditation for Law Enforcement Agencies (CALEA) accreditation.Design/methodology/approachThe authors performed keyword searches across 132 criminal justice, policing, and public administration journals to identify peer-reviewed articles that examine the relationship between CALEA accreditation and any output or outcome. Two keyword searches were utilized “commission on accreditation for law enforcement agencies” and “commission on accreditation of law enforcement agencies” in the event that authors misnamed the accrediting body. Only quantitative articles that utilized inferential statistics were included in the sample given that the authors aimed to assess the relationship between CALEA law enforcement accreditation and outputs and outcomes.FindingsOverall, there is a paucity of research on the relationship between CALEA accreditation and outputs and outcomes. Only nineteen, peer-reviewed, studies that utilize inferential statistics have been published on the topic as of the end of 2021. The largest number of studies explore the relationship between CALEA accreditation and community-oriented policing and gender representation. Given the dearth of quantitative studies on CALEA accreditation, and the lack of studies using experimental or quasi-experimental designs, current findings on the topic should not be viewed as proof of cause and effect relationships but as correlations.Originality/valueThis article represents the first systematic review of the correlates of CALEA accreditation.

PurposeThis paper examines the effect of the holy month of Ramadan on the returns and conditional volatility of cryptocurrency markets.Design/methodology/approachThe closing prices of six cryptocurrencies have been considered. The study employs different classical tests for checking if the efficiency behaviour is similar during Ramadan celebration days and non-Ramadan days. Besides, dummy variable regression technique for assessing this anomaly on returns and volatilities has been applied.FindingsAlthough no significant effect on returns and volatility for Litecoin has been found, the results provide evidence about the existence of the Ramadan effects in cryptocurrency markets. The results of the mean equations show the existence of Ramadan effect for Ethereum, Ripple, Stellar and BinanceCoin for all considered models. Significant effect on Bitcoin returns is found with an autoregressive model of order 1. The results of conditional volatility show Ramadan effect on volatility is not detected.Originality/valueFirst, a new contribution in the incipient study of cryptocurrency analysis. Second, a comprehensive review of recently published empirical articles about Ramadan effect on traditional assets has been carried out. Third, unlike most of the papers focussed on the study of Bitcoin, this study has been extended to six cryptocurrencies. Ramadan effect have not been analysed in cryptomarkets yet. This study come to fill this gap and analyses Ramadan effect, previously documented for traditional assets, in particular, stock index from Muslim countries, but not yet analysed in the cryptocurrency markets.
lncR26319/miR‐2834/EndophilinA axis regulates oogenesis of the silkworm, Bombyx mori

Published: May 2022

AbstractOocyte maturation is critical for insect reproduction. Vitellogenesis, the timely production and uptake of vitellogenin (Vg), is crucial for female fecundity. Vg is synthesized in fat body and absorbed by the oocytes through endocytosis during insect oogenesis. In the silkworm, Bombyx mori, we discovered that a nucleus‐enriched long‐noncoding RNA (lncRNA) lncR26319 regulates Endophilin A (EndoA) – a member of the endophilin family of endocytic proteins – through competitive binding to miR‐2834. The lncR26319‐miR‐2834‐EndoA axis was required for Vg endocytosis in the silkworm; loss of EndoA or overexpression of miR‐2834 significantly reduced egg numbers in virgin moths. In addition, accumulation of miR‐2834 resulted in pupal and adult deformation and reduced fecundity in females. The expression of Vg, 30‐kDa (30K) protein, and egg‐specific protein (Esp) decreased after knockdown of EndoA or overexpression of miR‐2834, while knockdown of miR‐2834 had an opposite effect on the expression of Vg, 30K protein gene, and Esp. These results suggest that the lncR26319‐miR‐2834‐EndoA axis contributes to the endocytic activity in the Vg uptake and leads to the normal progression of oogenesis in the silkworm. Thus, miR‐2834 and EndoA are crucial for female reproduction and could be potential targets for new pest management strategies in lepidopterans.
Building Type, Housing Density, and Water Use: Denver Water Data and Agent‐Based Simulations
Authors: Sampson David A. , Quay Ray , Horrie Mitch 
Published: May 2022

AbstractThis study examined simulated changes in total (and outdoor) water demand with increased dwelling units per unit area (DUUA) for seven building types (BTs) in the Denver Water service area. We utilized the Denver Water Demand Model — a spreadsheet tool that uses inputs such as BT, population, household size, number of units, etc. — to develop an “agent‐based” simulator to permit scenario analyses of future water use for different mixes of BTs. We examined household “movement” for new residents from lower density to higher density classifications. Increased residential density can be achieved through multiple pathways. For instance, a family could move from a large single‐family (LSF) unit to a single‐family home with a smaller lot footprint (SSF). Or, a family could move into a multi‐family housing development from a SSF. Our results suggest uneven, nonlinear efficiency gains in water use with increased density, depending on the specific BT movements. Simulation outputs indicate that the greatest gains in water savings per unit change in DUUA can be achieved with short movements over the lowest density classes (e.g., LSF to a SSF). In addition, results suggest that increasing irrigation efficiency (less water applied per unit area irrigated) may decrease total residential water demand by 5% to 25% over baseline; efficiency of irrigation may prove to be as effective, if not more, at reducing residential water demand as increasing housing density.
A continuous‐score occupancy model that incorporates uncertain machine learning output from autonomous biodiversity surveys
Authors: Rhinehart Tessa A. , Turek Daniel , Kitzes Justin 
Published: May 2022

Abstract

Ecologists often study biodiversity by evaluating species occupancy and the relationship between occupancy and other covariates. Occupancy models are now widely used to account for false absences in field surveys and to reduce bias in estimates of covariate relationships. Existing occupancy models take as inputs binary detection/non‐detection observations of species at each visit to each site. However, autonomous sensing devices and machine learning models are increasingly used to survey biodiversity, generating a new type of observation record (i.e. continuous‐score data) that reflects the model's confidence a species is present in each autonomously sensed file, instead of binary detection/non‐detection data. These data are not directly compatible with traditional binary occupancy modelling methods.

Here, we develop a new occupancy model that models continuous scores on a visit level as a Gaussian mixture, combining a distribution of scores for files that do contain the species of interest and a distribution of scores for files that do not. The model takes as input continuous scores for each autonomously sensed and classified file, along with an optional small number of binary, manually verified detection and non‐detection annotations.

We present a simulation study that shows that over a range of empirically realistic parameters, our model outperforms traditional occupancy models that are based on binary annotation alone. We also apply this new model to an empirical case study using data generated from five machine learning classifiers applied to autonomous acoustic recordings gathered in the eastern United States.

Because our occupancy model generalizes allowable input data beyond binary observations, it is particularly well‐suited to the increasing volume of machine learning classified data in ecology and conservation.

AbstractPurposeAngiostatic agents have proven effective in the treatment of macular oedema in patients with branch retinal vein occlusion (BRVO). However, treatment is inconvenient and expensive, and novel treatment regimens are warranted. We aimed to evaluate if combination treatment of navigated central retinal laser and aflibercept lowered the treatment burden in these patients.MethodsTreatment‐naïve patients with BRVO and macular oedema were included at two centres and randomized 1:1 to three monthly injections of 2.0 mg aflibercept with (Group A) or without (Group B) navigated central laser, followed by aflibercept as needed from month 4 through 12. Re‐treatment need was evaluated, and secondary endpoints included functional and anatomical outcomes and safety evaluated by retinal microperimetry.ResultsWe evaluated 41 eyes of 41 patients with a mean age of 69.6 years. Baseline median best‐corrected visual acuity (BCVA) was 70.0 letters, and median central retinal thickness (CRT) was 502 μm with no difference between Groups A (n = 21) and B (n = 20). Percentage of patients needing re‐treatment after month three was 71% and 80% (p = 0.72). At month 12, groups did not differ in number of injections after loading (1 versus 2, p = 0.43), change in BCVA (+12.8 versus +15.1 letters, p = 0.48), CRT (−195 versus −181 μm, p = 0.82), or retinal sensitivity (+3.3 versus +4.1 dB, p = 0.67).ConclusionIn treatment‐naïve BRVO patients, addition of navigated central laser to aflibercept did not lower treatment burden or affect functional or anatomical outcomes. A low number of intravitreal injections were needed for successful outcome in both treatment arms.
Team personality composition and team innovation implementation: The mediating role of team climate for innovation
Authors: Chatzi Sofia , Nikolaou Ioannis , Anderson Neil 
Published: May 2022

AbstractThe purpose of this study is first to explore the direct effects of team personality on team innovation implementation using different operationalizations for team‐level conscientiousness and emotional stability. Second, although past research offers guidance for the role of team personality in shaping team climate, only a few empirical studies have demonstrated this link. Thus, we examine how the operationalizations of the two personality characteristics at team level predict team innovation implementation via team climate for innovation. We test our model using a sample of 192 employees nested within 49 teams from different medium to large Greek organizations. Our results indicate that no effects for team mean personality are observed, but a range of effects emerge for team personality diversity. More specifically, team emotional stability diversity has a significant negative relation to team innovation implementation, whereas team conscientiousness diversity has not a direct effect on the performance criterion. However, team conscientiousness diversity is significantly related to team innovation implementation via its negative effect on team climate for innovation. Theoretical and practical implications for building innovative teams are discussed, and suggestions for future research are provided.

AbstractStress‐induced neuroepigenetic programming gains growing more and more interest in the studies of the etiology of posttraumatic stress disorder (PTSD). However, seldom attention is focused on DNA demethylation in fear memory generalization, which is the core characteristic of PTSD. Here, we show that ten‐eleven translocation protein 3 (TET3), the most abundant DNA demethylation enzyme of the TET family in neurons, senses environmental stress and bridges neuroplasticity with behavioral adaptation during fear generalization. Foot shock strength dependently induces fear generalization and TET3 expression in nucleus accumbens (NAc) in mice. Inhibition of DNA demethylation by infusing demethyltransferase inhibitors or AAV‐Tet3‐shRNA virus in NAc enhances the fear generalization and anxiety‐like behavior. Furthermore, TET3 knockdown impairs the dendritic spine density, PSD length, and thickness of neurons, decreases DNA hydroxymethylation (5hmC), reduces the expression of synaptic plasticity‐related genes including Homer1, Cdkn1a, Cdh8, Vamp8, Reln, Bdnf, while surprisingly increases immune‐related genes Stat1, B2m, H2‐Q7, H2‐M2, C3, Cd68 shown by RNA‐seq. Notably, knockdown of TET3 in NAc activates microglia and CD39‐P2Y12R signaling pathway, and inhibition of CD39 reverses the effects of TET3 knockdown on the fear memory generalization and anxiety. Overexpression of TET3 by Crispr‐dSaCas9 virus delivery to activate endogenous Tet3 in NAc increases dendritic spine density of neurons in NAc and reverses fear memory generalization and anxiety‐like behavior in mice. These results suggest that TET3 modulates fear generalization and anxiety via regulating synaptic plasticity and CD39 signaling pathway.
