Helicopter helping in the organization: its conceptualization, key characteristics and possible antecedents and consequences
Authors: Chou Shih Yung , Barron Katelin , Ramser Charles 
Published: February 2022

PurposeSince its inception, helping behavior has been viewed as a cooperative and affiliative behavior with prudent employee involvement. The paradox of employee involvement, however, implies that helping behavior can be intrusive and obstructive. The primary purpose of this article is to conceptualize helicopter helping as an intrusive and obstructive type of discretionary workplace behavior. In addition, the authors discuss possible antecedents and consequences of helicopter helping.Design/methodology/approachTo conceptualize helicopter helping, the authors utilized the ABI/INFORM Global, Academic Search Complete, Business Source Complete, PsycARTICLES and JSTOR Archive Collection databases focusing on the helping behavior and helicopter parenting research. In particular, the authors applied the hovering nature of helicopter parenting to the conceptualization of helicopter helping exhibited by an employee in the organization. Additionally, the authors discuss antecedents and consequences of helicopter helping by integrating the bright and dark side of helping behavior research.FindingsThe authors conceptualize helicopter helping as an employee's excessive involvement in and interference with coworkers' task environment. Based upon the conceptualization of helicopter helping, the authors further propose that the need for achievement, Type-A personality, group rewards, high-performance group norms, a hierarchy organizational culture and strong social ties are possible antecedents of helicopter helping. Furthermore, the authors suggest that helicopter helping can result in reduced organization-based self-esteem, general self-efficacy, group creativity and innovation, quality of social-exchange relationships, learning and development and increased organizational vulnerability.Originality/valueThis article is one of the few studies exploring helping behavior from an intrusive and invasive perspective. Theoretically, the authors advance the dark side of helping behavior literature. Drawing upon the propositions, the authors offer some managerial recommendations that help managers mitigate the intrusive and obstructive type of helping in the organization.
Poverty-alleviation programs in Tunisia: selection processes and targeting performance indicators at the regional level
Authors: Nasri Khaled 
Published: February 2022

PurposeThis paper aims to evaluate the social safety nets in Tunisia using targeting performance indicators which consider the divergence observed between the beneficiary selection process at the regional level and the official identification of poor.Design/methodology/approachIn the first part of this research, the author intend to quantify the degree of association between social programs coverage and poverty incidence, with special emphasis on the contribution of the center's targeting of regions and on the efforts of the regions themselves to reach their poor households. Next, the author measure four targeting errors: inclusion and exclusion errors, by eligibility and by poverty. These targeting errors help policymakers to understand how well a program is performing in terms of its specific eligibility criteria and knowing whether a social transfer is reaching poor people at the regional level.FindingsThe author’s empirical findings show there is a positive targeting differential which rejects the nullity of independence between poverty incidence and coverage of the program in Tunisia. The author then found that the overall targeting differential is accounted for by the intra-region component. After estimating the eligibility thresholds at the regional level, the author found that the targeting performance differs from one region to another, while some recorded gains that others did not.Originality/valueTo the best of our knowledge, no research has addressed the distinction between eligibility and poverty in the measurement of targeting errors. Thus, this paper contains research to fill this gap. It differs from previous studies in two important ways. First, the targeting errors will be estimated on the basis of the official eligibility criteria used at the regional level. Second, we estimate the eligibility thresholds by considering the programs coverage rate variations between regions based on quotas allocated to each governorate by the Ministry of Social Affairs (MSA).
Remote workers' experiences with electronic monitoring during Covid-19: implications and recommendations
Authors: Jeske Debora 
Published: February 2022

PurposeThis conceptual article outlines the known effects of employee monitoring on employees who are working remotely. Potential implications, as well as practitioner suggestions, are outlined to identify how practitioners can create more supportive employee experiences as well as apply these to workplace health management scenarios.Design/methodology/approachThis overview is based on a selective and practically oriented review of articles that hitherto considered the health implications of remote workers being monitored electronically over the last two years. This overview is subsequently complemented by a discussion of more recent findings that outline the potential implications of monitoring for remote employees, employees' work experience and workplace health management.FindingsSeveral practitioner-oriented suggestions are outlined that can pave the way to a more supportive employee experience for remote workers, who are monitored electronically by their employers. These include the various health and social interventions, greater managerial awareness about factors that influence well-being and more collaboration with health professionals to design interventions and new workplace policies. Organizations would also benefit from using audits and data analytics from monitoring tools to inform their interventions, while a rethink about work design, as well as organizational reviews of performance and working conditions further represent useful options to identify and set up the right conditions that foster both performance as well as employee well-being.Originality/valueThe article outlines practitioner-oriented suggestions that can directly and indirectly support employee well-being by recognizing the various factors that affect performance and experience.

Authors: Zhang Jiaqi , Cong Ming , Liu Dong , Du Yu , Ma Hongjiang 
Published: February 2022

Purpose
This paper aims to get rid of the traditional basic principle of using the motor as the variable stiffness drive source, simplify the structure of the exoskeleton and reduce the quality of the exoskeleton. This paper proposes to use shape memory alloys (SMA) as the variable stiffness drive source.

Design/methodology/approach
In this study, SMA is used to construct the active variable stiffness unit, the Brinson constitutive model is used to establish a dynamic model to control the active variable stiffness unit and the above active variable stiffness unit is used to realize the force control function and construct a lightweight, variable stiffness knee exoskeleton.

Findings
The dynamic model constructed in this paper can preliminarily describe the phase transformation process of the active variable stiffness unit and realize the variable stiffness function of the knee exoskeleton. The variable stiffness exoskeleton can effectively reduce the driving error under the high-speed walking condition.

Originality/value
The contribution of this paper is to combine SMAs to construct an active variable stiffness unit, build a dynamic model for controlling the active variable stiffness unit and construct a lightweight, variable stiffness knee exoskeleton.
Social media reviewing channels: the role of channel interactivity and vloggers’ self-disclosure in consumers’ parasocial interaction
Authors: Fazli-Salehi Reza , Jahangard Mahshid , Torres Ivonne M. , Madadi Rozbeh , Zúñiga Miguel Ángel 
Published: February 2022

Purpose
The purpose of this study is to examine the role of interaction-based features of social media reviewing channels and vloggers’ self-disclosure in consumers’ parasocial interaction with vloggers.

Design/methodology/approach
The study was conducted using an online survey, and data was collected using Amazon MTurk. The respondents were asked to think of an online reviewing channel that they watch regularly and subsequently responded to a series of questions. The analysis was conducted using structural equation modeling via AMOS.

Findings
Both channel interactivity and vloggers’ self-disclosure displayed a positive impact on consumers’ parasocial interaction with vloggers, which eventually led to perceived trustworthiness, brand identification, communal–brand connection with the channel, purchase intention toward the recommended products and willingness to pay a premium price for extra services.

Research limitations/implications
Future research can examine the robustness of the findings by using a sample of internet users who are similar in terms of frequency, enthusiasm and duration of active usage.

Originality/value
Marketing managers can benefit from the findings of this study by understanding the dynamics of how influencers shape consumer perception and behavior. Owners of reviewing channels can gain insight on how to strengthen their bond with their viewers.
Audit committee effectiveness, internal audit function, firm-specific attributes and internet financial reporting: a managerial perception-based evidence
Authors: Bananuka Juma , Nkundabanyanga Stephen Korutaro 
Published: February 2022

Purpose
This study aims to examine the contribution of audit committee effectiveness (ACE), internal audit function (IAF) and firm-specific attributes to internet financial reporting (IFR). It also seeks to understand which ACE and IAF attributes contribute to variances in IFR.

Design/methodology/approach
Data are collected through a questionnaire survey of 40 financial services firms.

Findings
The analysis shows that ACE and IAF significantly contribute to positive variances in IFR. It also shows that among the firm-specific attributes, only capital structure significantly contributes to positive variances in IFR. Audit committee meetings and authority contribute significantly to positive variances in IFR unlike audit committee expertise and independence. In terms of the IAF attributes, the risk management role and the regulatory compliance role contribute significantly to positive variances in IFR as compared to the governance processes role and evaluation of the internal control role.

Originality/value
This study enhances our understanding of the relationship between ACE, IAF, firm-specific attributes and IFR in an environment where IFR is not mandated and where corporate governance practices are very much in infancy. This is especially so given that for the first time, to the best of the authors’ knowledge, the contribution made by ACE, IAF and firm-specific attributes in IFR using evidence from an African developing country (Uganda) is now documented in a single study.
The role of virtual reality interactivity in building tourists’ memorable experiences and post-adoption intentions in the COVID-19 era

Published: February 2022

PurposeThis study aims to examine the impact of virtual reality (VR) interactivity elements, including synchronicity, two-way communication and active control, on tourists’ VR memorable experiences, and the subsequent effect on tourists’ word-of-mouth (WOM) and VR continuance intention.Design/methodology/approachThe research model was tested using self-administrated survey data from 285 Chinese tourists who were experienced in travel and VR tourism activities. Partial least squares–structural equation modelling was adopted to perform latent variable analysis.FindingsVR interactivity elements, including synchronicity, two-way communication and active control, play a considerable role in driving tourists’ VR memorable experiences, which in turn drive tourists’ WOM and VR continuance intention.Research limitations/implicationsCross-sectional, single country data was used and thus the generalisability of the findings may be limited. Future research is recommended adopting a longitudinal approach to compare the relationship between constructs in countries with diverse cultures.Practical implicationsThe findings provide guidance for tourism marketers to use the interactive features of VR, including synchronicity, two-way communication and active control, to drive tourists’ memorable experiences and thereby strengthen tourists’ referral and continuance intention.Originality/valueScholarly attention on the importance of VR interactivity in driving tourists’ memorable experiences and behavioural intention is limited. This study contributes to the tourism marketing literature by empirically testing the research model to reveal the importance of VR interactivity elements, including synchronicity, two-way communication and active control, to drive tourists’ VR memorable experiences and behavioural intentions.
Migration tactics and connectivity of a Nearctic–Neotropical migratory shorebird
Authors: Herbert John A. , Mizrahi David , Taylor Caz M. 
Published: February 2022

Abstract

During long‐distance spring migrations, birds may rest and refuel at numerous stopover sites while minimizing the time to reach the breeding grounds. If habitat is limited along the migration route, pre‐breeding birds optimize flight range by having longer stopovers at higher quality sites compared to poorer quality sites. Stopover duration also depends on distance remaining to breeding grounds, ecological barriers and individual characteristics.

We assessed spring migration tactics and connectivity of a Nearctic–Neotropical migratory shorebird, the semipalmated sandpiper Calidris pusilla, at two sites with known relative habitat quality on the northern Gulf of Mexico (NGOM) coast, the first land encountered after crossing the Gulf of Mexico (GOM).

We used automated radio telemetry (Motus) to estimate stopover duration and probability of departure. Migration speed was estimated for individuals detected at subsequent receivers on the Motus network. To measure migratory connectivity, we used morphometrics and the Motus network to assign general breeding regions. Additionally, feather stable isotope ratios of C and N provided coarse information about overwintering regions.

Stopover duration declined with higher fuel loads at capture as expected under a time‐minimizing strategy. After accounting for fuel load, stopover duration was approximately 40% longer at the higher quality site. We found no detectable effect of age, sex or breeding location on stopover behaviour. The probability of departure was strongly affected by humidity and also by tailwind and weather conditions. Birds stopping at the higher quality site had earlier apparent arrival to the breeding grounds. The Louisiana coast is an apparent stopover hub for this species, since the individuals were departing to range‐wide breeding regions and isotope values suggested birds were also using widespread wintering regions.

Our study shows how high‐quality, coastal wetlands along the NGOM coast serve a critical role in the annual cycle of a migratory shorebird. Stopover behaviour indicated that high‐quality habitat may be limited for this species during spring migration. As threats to the GOM coast increase, protection of these already limited wetlands is vitally important.
Plant life‐history traits rather than soil legacies determine colonisation of soil patches in a multi‐species grassland

Abstract

Interactions between plants and soil biota are increasingly shown to play critical roles in plant species coexistence processes. Plant species coexistence is thought to be promoted via biotic legacies that plant species leave behind in the soil after a plant disappears. These soil legacies are hypothesised to supress colonisation success when the preceding plant is of the same species, that is, when a plant species encounters its own, species‐specific soil antagonists.

However, colonisation of vacant spots in plant communities is in the first place determined by the ability of plants to reach such vacant locations. We currently lack an understanding of the explicit role of soil legacy effects and their relative contribution to colonisation processes in plant communities consisting of plant species inherently differing in colonisation ability.

In experimental, outdoor plant communities consisting of eight grassland species, we tested the effect of five differently conditioned soil patches on plant species colonisation success over three consecutive growing seasons. We found that colonisation success was largely determined by the species' reproductive strategy, lateral spread and growth rate, and not by the plant species that conditioned the soil patch. Fast spreading, clonal plant species reached the soil patches first and initially attained the highest biomass inside the patch. One year later, slower spreading plant species colonised the patch via seedlings. Species with intrinsically high growth rates attained the highest biomass, decreasing biomass of the initial colonisers. While subtle differences between conditioned soil patches did occur, these were not strong enough to overcome the inherent differences in colonisation ability between the various plant species.

Synthesis. Our results reject the hypothesis that colonisation of vacant soil patches in plant communities is strongly affected by the legacy that is left behind by the preceding plant species. Instead, plant species life‐history strategy plays a prominent role, driving sequential plant species replacements. Based on our results and recent accounts in literature we present a conceptual model for local cyclic dynamics in grassland communities, where soil legacy plays a role in affecting the performance of established plant species rather than colonisation of vacant patches.
Maternal cannabis use during pregnancy and maternal and neonatal outcomes: A retrospective cohort study
Authors: Koto Prosper , Allen Victoria M. , Fahey John , Kuhle Stefan 
Published: February 2022

AbstractObjectiveTo examine the relationship between reported prenatal cannabis use and neonatal and maternal outcomes and whether the legalisation of cannabis in Canada affected the rates of reported use or the association with maternal and neonatal outcomes.DesignPopulation‐based retrospective cohort study.SettingRoutinely collected data in a real‐world setting.PopulationAll women in the Canadian province of Nova Scotia with singleton births between 1 January 2004 and 30 June 2021.MethodsThe association between cannabis use and maternal and neonatal outcomes was examined using generalised linear models with inverse probability weighting.Main outcome measuresMaternal and neonatal outcomes in the peripartum and postpartum period.ResultsRates of reported cannabis use in pregnancy increased from 1.3% to 7.5% over the study period with no appreciable change in slope after legalisation in 2018. Infants of mothers reporting cannabis use in pregnancy were more likely to have major anomalies and a 5‐minute Apgar score ≤7, require neonatal intensive care unit admission, and had lower birthweight, head circumference and birth length than infants of mothers not reporting cannabis use. These associations did not differ before and after legalisation.ConclusionsReported cannabis use during pregnancy is associated with early postnatal complications and reduced fetal growth, even after taking into account a range of confounding factors. Rates of reported cannabis use during pregnancy increased over the past 5 years in Nova Scotia with no apparent additional effect of legalisation.
The relation of childhood adversity and antisociality to suicide attempts in men admitted to forensic psychiatric hospital
Authors: Hui Jeanette , Hilton N. Zoe 
Published: February 2022

AbstractSuicide is a leading cause of death in custody. Although previous studies with prison inmates suggest a strong relation between childhood adversity and suicidal behavior, as well as between childhood adversity and antisociality, this has not been explored in the forensic psychiatric system. We compared 211 men admitted to a forensic hospital having a lifetime history of suicide attempts with 275 men with no suicide history in the same institution. Data were retrospectively coded from information gathered during their assessment and medical records. We examined associations of adverse childhood events and antisociality with suicide attempt history in a series of regression analyses. Childhood adversity was present in majority of individuals and significantly more common for individuals with a history of suicide attempts (76.8%) than those with no suicide attempts (63.3%). The suicide attempt group also experienced a greater number of adverse childhood events. Physical abuse, parental separation, and parental psychiatric history during childhood were associated with suicide attempts. Men with a suicide attempt history had higher antisociality scores than the comparison group and adult antisocial behavior partially mediated the relationship between adverse childhood experiences and suicide attempts. Men in forensic hospital who have suffered multiple experiences of childhood adversity are at increased risk for exhibiting antisocial behavior and engaging in suicidal attempts. Early interventions targeted toward antisociality and trauma‐informed care in the forensic hospital are needed to support the mental health of the forensic population.
Heat and let dye: Fixing blood‐contaminated fingermarks using heat

Published: February 2022

AbstractBlood‐contaminated fingermarks are significant evidence for forensic investigators in high‐profile cases providing a direct link between the suspect and the crime. Although these marks are often visible, blood enhancement techniques are operationally used to recover maximal ridge detail. The standard protein dye‐staining procedure includes a chemical blood‐fixing step, which requires an initial, prolonged drying period, for natural coagulation to occur. However, in special cases, when it is crucial to detect forensic traces quickly, there is a need to speed up the enhancement process. This study explored, both theoretically and empirically, the use of heat as an alternative method to the standard chemical fixing. Three consecutive experiments were conducted in which blood‐contaminated fingerprints were deposited on different types of surfaces (car parts, glass, and flooring tiles), and heated for different periods, prior to development by amido black solution. The results showed that heat was successful in fixing blood, while the required temperature and heating durations, were inversely proportional. This observation was in correlation with theoretical heat‐transfer data, calculated by the Lumped Heat Capacity model, also demonstrating the impact of the thermal time constant of each surface, on the conditions required for the full fixing of blood. The experimental findings led to a design of a portable, and tailor‐made heating device, examined for the use in crime scenes, allowing to shorten the necessary fixing process from hours to minutes. For future crime‐scene work, this novel approach may be utilized for a rapid blood‐fixing, especially in cases when the scene cannot be preserved.
