Neural network based harmonic elimination in single-phase inverters
Authors: Duranay Zeynep Bala 
Published: August 2022

Purpose
This study aims to present the experimental results for neural network (NN) based harmonic elimination technique for single-phase inverters.

Design/methodology/approach
Switching angles applied to power switches are determined using the NN technique based on the harmonics to be suppressed. Thus, besides controlling the output voltage, NN controller provides elimination of predetermined harmonics from output signal of single-phase inverter. Simulation and experimental results for the elimination of 15 and 20 low-order harmonics are presented. The switching angle values calculated by a NN , fuzzy logic and Newton–Raphson are compared for elimination of first 10 harmonics.

Findings
This paper provides the harmonic spectra showing that first 15 and 20 harmonics are suppressed from output signal. The NN is proved to give closest results to angle values calculated by Newton–Raphson’s numerical solution method.

Originality/value
The value of this paper is to verify the simulation results with the experimental result for the elimination of 15 and 20 low-order harmonics. Both the simulation and the experimental results demonstrate the success of the NN based selected harmonic elimination.

Published: August 2022

PurposeThe purpose of this study is to examine the components of the utilitarian and hedonistic dimensions of the quality of mobile banking services, their impact on customer satisfaction, as well as the effects of satisfaction on word of mouth (WOM) and intention to use.Design/methodology/approachThe analysis includes 307 mobile banking users in the Republic of Serbia. Reliability analysis, confirmatory factor analysis, structural equation modelling and multigroup analysis are applied in the paper.FindingsThe results show that security/privacy, perceived usefulness, perceived ease of use, design and enjoyment are important drivers of customer satisfaction, and that satisfaction has very strong effects on WOM and intention to use. In addition, there are apparent differences in the relationships between the two groups of respondents observed: innovators and followers.Originality/valueThe originality of the paper lies in the innovative model that includes a combination of the TAM model and the utilitarian/hedonistic dimension of the quality of mobile banking services. An element of the study which is of particular value is its segmentation of customers into innovators and followers – dividing respondents into two groups depending on whether they are among the first people in their environment to start using mobile banking services.
Mind the gap: public equity as a financing solution for medium-sized enterprises and the influence of national culture
Authors: Koch Lisa Paula , Crossan Kenny , Jaworski Piotr Marek 
Published: August 2022

PurposeThis research focuses on the demand from medium-sized firms to access public equity as a source of finance. The acceptance of public equity differs strongly between countries, particularly between the United Kingdom and Germany. Therefore, this research aims to identify the impact of national culture on the decision to go public in these two countries.Design/methodology/approachThe theoretical framework builds on the satisficing theory of rationality, the pecking-order theory as well as Hofstede's cultural dimension theory. Using a questionnaire, over 1,000 medium-sized businesses in the United Kingdom and Germany were surveyed.FindingsThe findings demonstrate that British medium-sized firms are more open to using public equity as a source of finance than their German counterparts. The results indicate that national culture not only affects the decision to go public but also has a negative impact on uncertainty avoidance and long-term orientation.Originality/valueThe originality of the research lies in the focus on medium-sized firms and the effects of cultural differences between the United Kingdom and Germany. No previous research has explored how culture influences the decision to go public using a dataset generated from medium-sized firms in the United Kingdom and Germany.
When morally good employees become bad: the role of unethical requests and wrong judgments at the workplace
Authors: Mumtaz Sana 
Published: August 2022

PurposeThis research focuses on the distinct group of high-status employees commonly referred to as workplace vigilantes, and conceptually investigates how unethical requests by these individuals impact the behavior and attitude of other employees over time using the social identity theory.Design/methodology/approachFor developing a conceptual model, literature from the domains of social identity, organizational behavior and general management was searched through Google Scholar. To search the literature, some key terms such as “unethical activities”, “Islamic work ethics” and “social identity” were searched and analyzed.FindingsUsing the social identity theory, a conceptual process model is developed which suggests that when high-status employees propose unethical requests to employees, individuals with high morality are likely to refuse those unethical requests to protect their self-categorizations. However, taking the unfair advantage of their illegitimate powers, high-status employees are likely to eventually make wrong judgments and give unnecessary punishments to moral employees. It is further argued that consistent victimization is likely to negatively impact the social identity of such employees and leads to irritability in moral employees, particularly when such individuals are unable to get the requisite social support from their leaders.Originality/valueWhile a considerable body of literature has focused on the antecedents and consequences of intense unethical business practices and the crucial role of leaders in such activities, limited attention has been given to the role of other employees and how they engage in mild unethical misconduct regularly, which is the key focus of this research. The novel conceptual framework needs to be tested in diverse contexts for further development and validation.

Abstract

Plants produce an astonishing diversity of specialized metabolites as defences against herbivores, pathogens or detrimental abiotic conditions. Plants growing at different elevations are exposed to different biotic and abiotic conditions and typically show pronounced differences in their chemistry. Understanding how these differences arise through changes in various measures of chemical diversity can inform us concerning factors that contribute to the variety of metabolites found among plants.

We focused on elevational changes in concentration, richness and intra‐ and interspecific variation in specialized chemistry in willows (Salix, Salicaceae) and compare them among metabolite classes with different functions. We aim to show how these various measures of chemical diversity change with elevation to reveal trends contributing to changes in plant chemistry along major ecological gradients.

We studied chemistry, herbivory and fungal pathogen damage in an assemblage of seven willow species along an elevational gradient in the Alps (800–2600 m a.s.l.). We examined trends in chemical diversity using untargeted metabolomics, and further quantified trends in three specific classes: proanthocyanidins and salicinoids involved in biotic interactions, and flavonoids involved mainly in abiotic protection. We use measures of willow chemistry that take structural relatedness of metabolites into account to show if the roles of structurally distinct metabolites change with elevation.

Willows from low elevations exhibited greater proanthocyanidin concentration and structural richness of flavonoids. In contrast, willows from high elevations showed greater structural richness of salicinoids and greater variation in total metabolite composition at both the intra‐ and interspecific levels. The trends in salicinoid richness and proanthocyanidin concentration were explained by elevational changes in temperature.

Our results show how elevational differences in plant chemistry arise through trends in various aspects of their chemical diversity. Willows at high elevations showed reduced structural richness of metabolites involved in abiotic protection. This may reflect focused investment in metabolites with the highest ecological benefit relative to their concentration in high‐elevation willows. At the same time, they possessed greater richness of metabolites involved in biotic interactions, while variation in microhabitat preferences among high‐elevation species likely contributed to the high variation in their total metabolite pool.

CODA: The Racial Ecologies of Urban Wetlands
Authors: Ranganathan Malini 
Published: August 2022

AbstractIn this coda to the intervention on slow violence and the administration of urban injustice I reflect on the role of racialization—broadly defined—in creating deeply unequal and risk‐laden wetland ecologies. I identify ‘racial ecologies’ and ‘ambivalence’ as two key concepts tying together wetland politics across the contexts of Philadelphia and Mumbai. While the concept of ‘racial ecologies’ underscores how systems of human valuation (including racism, casteism and religious discrimination) are ordered through ecological and property valuation, the concept of ‘ambivalence’ stresses the materiality and strategic governing logic which underpins wetland ecologies.
Does labour income react more to income tax or means‐tested benefits reforms?
Authors: Sicsic Michaël 
Published: August 2022

AbstractI provide estimates of compensated elasticities of labour income with respect to the marginal net‐of‐tax rate on the 2006–15 period for France, exploiting not only income tax reforms but also means‐tested benefits reforms. I use semi‐parametric graphical evidence and a classic two‐stage least‐squares estimation applied to a rich data set including both financial and socio‐demographic variables. I obtain an estimated compensated elasticity on the intensive margin around 0.2–0.3 in response to income tax reforms, and around 0.1 in response to in‐work benefit reforms, while I found no statistically significant response to family allowance reforms. I show that the difference between elasticities contradicts the theoretical prediction of the classical labour supply model. These asymmetric responses are very robust to a large number of robustness checks. The most plausible explanation is that income tax reforms are more salient and better perceived than benefit reforms. I also highlight an average compensated elasticity of 0.1 for all transfers on the intensive margin and provide heterogeneous elasticities depending on types of people, which could be used for optimal tax analyses.
Motivating Employees with Goal‐Based Prosocial Rewards*
Authors: Berger Leslie , Guo Lan , Presslee Adam 
Published: August 2022

ABSTRACTA recent trend in organizations is to motivate employees with goal‐based prosocial rewards, whereby employees must donate their rewards to charities upon goal attainment. We examine the motivational effects of goal‐based prosocial rewards versus cash rewards under different levels of goal difficulty. We develop our hypotheses based on affective valuation theory, which posits that when valuing uncertain outcomes by affect rather than calculation, individuals are largely insensitive to changes in probability of the outcomes, including probability of goal attainment. Experiment results support our hypotheses. Specifically, we find that employees who are rewarded with prosocial (vs. cash) goal‐based rewards are more likely to adopt an affective valuation approach. Consequently, when employees are assigned either an easy goal or a stretch goal, their effort is higher when incentivized with a goal‐based prosocial reward than a cash reward. Furthermore, there is a less curve‐linear relationship between goal difficulty and effort with prosocial (vs. cash) goal‐based rewards. These findings highlight for incentive system designers the motivational advantage of goal‐based prosocial rewards relative to traditional cash rewards. Furthermore, we extend the academic literature by showing how affect‐rich rewards such as prosocial rewards can influence employees' assessment of the probability of goal attainment.
The Harrah's epigraphic heritage: Arabic graffito from the Black Desert in north‐eastern Jordan referring to the Umayyad caliph Hishām b. ʿAbd al‐Malik
Authors: Alhatlani Abdullah Saad , Al‐Manaser Ali 
Published: August 2022

AbstractThe aim of this article is to republish, reread and interpret an Arabic inscription from the Black Desert, north‐eastern Jordan, to shed light on the practice of the dating system used before the Umayyad era, in which the dating of the inscription is linked to a specific event. The inscription was re‐discovered by the present authors during the 2019 Badia Epigraphic Survey. It dates to the death of Hishām, who, as can be assumed, is the Umayyad caliph Hishām b. ʿAbd al‐Malik (r. 724–743CE). In addition, this paper argues that according to the epigraphic records, when a caliph died, his title was removed.

AbstractObjectiveTo evaluate the influence of extensive genetic and psychosocial confounding on the association between early childhood infection and five major psychiatric disordersMethodsA case‐cohort study including participants from the Danish iPSYCH2012 sample, a case‐cohort sample where all cases born between May 1, 1981, and December 31, 2005, diagnosed with attention‐deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), bipolar affective disorder (BIP), Major Depressive Disorder (MDD) or schizophrenia (SCZ), were identified and pooled with a representative sample (subcohort) of the Danish population. We used Cox proportional hazards regression customized to the case‐cohort setup to calculate hazard ratios of outcome with 95% confidence intervals (CIs), following exposure to early childhood infection before the age of 5 years for ADHD and ASD, and before the age of 10 years for BIP, MDD, and SCZ. To evaluate psychosocial confounding we included sex, calendar period, sibling infections, urbanicity, parental socio‐economic status, parental mental health information, and polygenic risk scores for all five disorders, as covariates. To estimate how liability for psychiatric disorders measured through the PRS influenced the risk of early childhood infection, we calculated odds ratios (ORs) with 95% CIs, using logistic regressionResultsEarly childhood infection was associated with ADHD, ASD, MDD, and SCZ with number of childhood infections increasing the hazard. The HR was still significant in the model with full adjustments after 1 infection for ADHD (HR 1.29, 95% CI: 1.19–1.41), ASD (HR 1.28, 95% CI: 1.18–1.40), MDD (HR 1.23, 95% CI: 1.14–1.33), and SCZ (HR 1.21, 95% CI: 1.07–1.36), but not for BIP (HR1.17, 95% CI: 0.96–1.42). Probands exposed to sibling infections, but not own infection had an absolute risk of ADHD, BIP, MDD, and SCZ that closely approached the absolute risk for individuals exposed to own infections. We found evidence of gene–environment correlation with higher PRS of MDD and to some extent SCZ increasing the risk of infections and higher PRS of BIP associated with significantly decreased riskConclusionEarly childhood infection is significantly associated with ADHD, ASD, MDD, and SCZ and not explained by genetic or psychosocial confounding. Although we found evidence of gene–environment correlation, it had minor impact on the results

AbstractBackground and ObjectivesPublic health surveillance for overdose sometimes depends on nonfatal drug overdoses recorded in health records. However, the proportion of total overdoses identified through health record systems is unclear. Comparison of overdoses from health records to those that are self‐reported may provide insight on the proportion of nonfatal overdoses that are not identified.MethodsWe conducted a cohort study linking survey data on overdose from a national survey of Veterans to United States Department of Veterans Affairs (VA) health records, including community care paid for by VA. Self‐reported overdose in the prior 3 years was compared to diagnostic codes for overdoses and substance use disorders in the same time period.ResultsThe sensitivity of diagnostic codes for overdose, compared to self‐report as a reference standard for this analysis, varied by substance: 28.1% for alcohol, 23.1% for sedatives, 12.0% for opioids, and 5.5% for cocaine. There was a notable concordance between substance use disorder diagnoses and self‐reported overdose (sensitivity range 17.9%–90.6%).Discussion and ConclusionsDiagnostic codes in health records may not identify a substantial proportion of drug overdoses. A health record diagnosis of substance use disorder may offer a stronger inference regarding the size of the population at risk. Alternatively, screening for self‐reported overdose in routine clinical care could enhance overdose surveillance and targeted intervention.Scientific SignificanceThis study suggests that diagnostic codes for overdose are insensitive. These findings support consideration of alternative approaches to overdose surveillance in public health.

Published: August 2022

AbstractSince trimethoprim (TMP) dose‐dependently inhibits the excretion of potassium, a population kinetic–pharmacodynamic analysis was performed to establish an adequate dosing schedule and characterize factors of hyperkalaemia. Dataset was constructed using a retrospective observational cohort of hospitalized patients (>18 years) with oral sulfamethoxazole/trimethoprim formulation. The model integrated a kinetic model for TMP, a urinary TMP concentration–response curve and a kinetic model for serum potassium using an indirect response model. The model was a function of body weight, renal function, serum potassium levels and TMP dosing schedule. We evaluated covariates by the stepwise forward and backward selection methods. The Monte Carlo simulation determined the probability of hyperkalaemia (>5.5 or >6.0 meq/L) according to the dosing schedule, renal function and covariates. This study included 317 patients [age 62 (42–72) years] with 4359 serum potassium levels. The significant covariate was non‐steroidal anti‐inflammatory drugs (NSAIDs), with a 72.3% reduction in 50% inhibitory concentration. Monte Carlo simulation revealed that high‐dose TMP (400 mg thrice daily) co‐administered with NSAIDs led to mild hyperkalaemia (>10%) and severe hyperkalaemia (approximately 5%), regardless of renal function. In conclusion, clinicians should pay attention to hyperkalaemia with TMP high‐dose and co‐administered NSAIDs.
Sexual dysfunction among males and females with bipolar disorder and healthy subjects: The burden of illness severity

Published: August 2022

AbstractObjectivesSexual dysfunction has wide‐ranging impacts on the person's functioning and quality of life, being associated with higher severity of psychiatric illnesses and poor therapeutic response. Given the paucity of data on this topic in bipolar disorder (BD), we investigated sexual functioning among males and females with BD and healthy controls (HCs) as well as whether illness severity markers and subthreshold mood symptoms were associated with sexual dysfunctions in BD patients.MethodsThe study included 80 BD outpatients and 70 HCs. Sexual functioning was evaluated using the validated, gender‐specific Changes in Sexual Functioning Questionnaire (CSFQ‐14).ResultsBD patients had a significantly poorer sexual functioning than HCs (p < 0.00001). The odds of sexual dysfunction doubled given a one‐unit increase in the number of suicide attempts (adjusted OR = 2.01, 95% CI:1.23–3.55; p < 0.01) and increased by 60% for every additional hospitalization (p < 0.05). Greater illness duration was associated with arousal/orgasmic (p < 0.05) and overall sexual dysfunctions (p < 0.01). BD patients with more mixed or (hypo)manic episodes had a lower likelihood of libido loss and arousal/orgasmic disturbances (p < 0.01), respectively. Higher levels of subthreshold depressive symptoms increased by 20% the odds of sexual interest/frequency dysfunctions (p < 0.05), and up to 60% regarding orgasmic disturbances (p < 0.01).ConclusionsSexual functioning may be a useful proxy of illness severity as well as a relevant dimension to more deeply characterize BD patients. Further studies are warranted to replicate our findings, to evaluate temporal associations between sexual dysfunctions and illness severity across the BD mood and treatment spectrums and to explore neurobiological underpinnings of these associations.
Conducting video therapy with adults with an intellectual disability: A qualitative study of qualified and trainee psychologists' experiences
Authors: Blocksidge Hope , Willis Lara , Codd Jon 
Published: August 2022

AbstractBackgroundOnline therapy is becoming increasingly popular as well as necessary. There is little research regarding the experience of psychologists delivering online therapy to individuals with an intellectual disability.MethodThe study used online semistructured interviews and interpretive phenological analysis to explore the experiences of five psychologists delivering online therapy to individuals with an intellectual disability.FindingsFour superordinate themes were generated from the data: Environment: “You can't control the environment”; Person centred: “I do not think it's one size fits all”; Rapport: “slightly trickier to build”; and Clinician ability and experience: “it was a bit of a learning process”. Psychologists spoke of prior negative beliefs and a range of challenges to video therapy. Their discomfort with using this technology was noted; however, a motivation to continue offering therapy to clients overweighed this. All participants concluded with benefits to using video therapy, notably increased accessibility.ConclusionA hybrid model including face‐to‐face and online therapy appears preferable for future ways of working. Training is recommended for professionals and individuals supporting clients, and an assessment tool for the suitability of online therapy. Further research exploring online therapy experiences of people with intellectual disabilities is required.
