Published: January 2023

AbstractAccording to the upper echelon's theory, the decision‐making process in regard to competitive strategies by the top management has an enduring impact on firm performance (Hambrick & Mason, 1984). Moreover, the attributes of the individuals in top management may also affect the decision‐making process. The purpose of this research is to analyze the board gender diversity impact on the financial performance of the non‐financial companies of Pakistan. Qualitative comparative analysis (QCA) is employed which is premised on Boolean algebra that sets foundation for the theoretical framework of complexity theory. The sample comprises of 74 non‐financial firms listed on the KSE‐100 Index. The results are modelled as a component of the intermediate solutions with board‐ level variables and gender diversity for the outcome variable (i.e., EVA and Tobin's Q). From board level variables, the impact of gender diversity and foreign directors is identified among most of the combinations whereas leverage is the prominent variable within the firm level variables, the boards of which tend to be small. The results showed a heterogeneous nature of response as board gender diversity exhibited stronger association in some configurations and in some cases it exhibited weaker association similar to that of (Pandey et al., 2022).Originality: This study is an attempt to explore the of board gender diversity role in a firm's performance using board level and firm level variables. Therefore, this work adds to the prior research by adding a complementarity‐based methodology for analyzing board gender diversity.

Published: January 2023

AbstractObjectiveIn the wake of the COVID‐19 pandemic, the use of teletherapy has become more pervasive than ever. Many therapists faced this move to a remote setting with little experience or training. We aimed to qualitatively examine therapists' subjective experience of providing teletherapy, including changes in technique, the therapeutic relationship, and the therapeutic process.MethodsThirty‐one psychotherapists participated in semistructured interviews. Interviews were recorded, then transcribed and analyzed using the Consensual Qualitative Research method.ResultsTherapists typically reported a change in the therapeutic relationship in terms of an increased sense of disconnection as well as shifts in various aspects of the relational dynamics, and they also typically experienced differences in the therapy process due to changes in patient and therapist engagement in the therapeutic work. Additionally, some therapists also reported that they became more active and directive in sessions, took a more informal, personal, or relaxed approach to interacting with patients, and while the emotional connection changed and they missed the energy and intimacy of in‐person sessions, the relationship in telesessions felt more authentic and human for some, and teletherapy also provided a way to discuss new dimensions in the process.ConclusionOverall, these results suggest great variability in therapists' subjective experiences with teletherapy, and present teletherapy as a distinct therapy format in many aspects. Further process‐level research and subsequent training is needed to better equip therapists to navigate teletherapy's challenges and harness its unique opportunities.
Mentoring first‐generation college students: Examining distinct relationship profiles based on interpersonal characteristics, support provision, and educational capital
Authors: Hagler Matthew A. 
Published: January 2023

AbstractThe goal of this study was to identify distinct profiles among first‐generation college students' mentoring relationships based on interpersonal characteristics, provision of college‐related support, and mentors' educational capital. First‐year, first‐generation undergraduates (n = 176) identified up to six mentors, rating various relationship characteristics, the types and degrees of college‐related support each mentor provided, and each mentor's level of educational attainment. Ratings were used as indicators in a multilevel latent profile analysis among mentoring relationships (n = 254), accounting for clustering of multiple mentors within individual participants. A 3‐profile solution best fit the data. Profiles were distinguished by closeness, frequency of contact, degree of college‐related support provided, and mentors' educational attainment. Mentors with high educational attainment (“High‐Capital Mentors”) provided the most support for college‐related issues, even with relatively infrequent contact. During their transition to higher education, first‐generation college students appear to receive more active mentoring from adults with educational capital, although other adults may serve important functions not captured by the college‐specific measures used in this study.
mRNA m6A methylation in wood frog brain is maintained during freezing and anoxia

Published: January 2023

AbstractFreeze tolerance is an adaptive strategy that wood frogs (Rana sylvatica) use to survive the subzero temperatures of winter. It is characterized by a variety of metabolic and physiological changes that facilitate successful freezing and anoxia. As both mRNA regulation and posttranslation protein modification have been implicated in freeze tolerance, we hypothesized that posttranslational RNA regulation is also involved in coordinating freeze‐thaw cycles and metabolic rate depression. As such, we investigated the most abundant RNA modification, adenosine methylation (N6‐methyladenosine; m6A) in wood frog brains during 24 h periods of freezing and anoxia. This was followed by an examination of levels of RNA methyltransferases, demethyltransferases, and the readers of RNA methylation. Despite relative levels of methylation on mRNA remaining constant throughout freezing and anoxia, a significant increase in relative abundance of m6A methyltransferases METTL3 and METTL14 was observed. In addition, we investigated the effect of m6A RNA methylation on mRNA triaging to stress granules and report a significant increase in stress granule markers TIAR and TIA‐1 in both freezing and anoxia. Our findings are the first report of RNA posttranslational regulation during metabolic rate depression in the wood frog brain and suggest that the dynamic RNA methylation observed is not directly linked to mRNA regulation during periods of extreme metabolic reorganization, warranting future investigations.
Real‐world treatment outcomes of sofosbuvir‐based regimens for treatment of chronic hepatitis C with and without human immunodeficiency virus co‐infection

Published: January 2023

AbstractBackground and AimThe efficacy of sofosbuvir (SOF)‐based regimens in the treatment of chronic hepatitis C (HCV) patients with and without human immunodeficiency virus (HIV) co‐infected patients in real‐world setting is limited.MethodsThis was a retrospective cohort study, conducted between 1 January 2017 and 31 December 2021 at Bamrasnaradura Infectious Disease Institute, Thailand. All HCV patients received 12 weeks of SOF‐based regimens and had follow‐up for at least 12 weeks after therapy discontinuation. The primary outcome was sustained virological response (SVR) at 12 weeks after the end of treatment. Treatment outcomes were compared between HCV patients with and without HIV co‐infection.ResultsA total of 163 patients were included in the study, 130 (79.8%) were HCV/HIV co‐infected, and 33 (20.2%) were HCV mono‐infected. Of all, 106 (64%) patients received SOF and ledipasvir. Genotype 1 (GT1) was predominant at 66.4%, followed by GT3 at 22.2%, and GT6 at 11.4%. Overall SVR was 96.9%. SVR in HCV mono‐infected was 96.9% and SVR in HIV‐HCV co‐infected patients was 96.9%. The factor associated with SVR was HCV genotype (P = 0.001). Patients with HCV GT6 had lower SVR rates compared with GT1 and GT3 patients (83.3%, 100%, and 97.1% [P = 0.000] respectively). There was no association between SVR and other factors such as gender, age, BMI, underlying cirrhosis, baseline HCV viral load, or prior treatment history (all P > 0.05). All patients completed 12‐week SOF‐based treatment.ConclusionIn real‐world setting, HCV treatment with SOF‐based regimens between patients with and without HIV co‐infection showed high rates of SVR. SOF‐based regimens were highly efficacious and tolerated.
Entrepreneurs' mobile phone appropriation and technical efficiency of informal firms in Dakar (Senegal)

Published: January 2023

AbstractIn Africa, entrepreneurship remains predominantly informal, but the rapid spread of mobile phone and Internet use is often viewed as an opportunity to boost the productivity and output of informal firms. Yet little is known on how informal entrepreneurs use these technologies for their business. The purpose of this paper is to open the black box of ‘mobile usage’ and investigate its effects on the performance of informal micro and small enterprises. To do so, we develop an original conceptual framework of mobile usage and apply a three‐step empirical approach based on a unique dataset of informal firms in Dakar. The first step allows us to identify rich ‘mobile usage’ measures that examine the different economic functions supported by mobile phones (coordination, finance and management) and the multiple dimensions of use (range and intensity). The second step identifies four user profiles with specific forms of appropriation: disconnected entrepreneurs, networkers, Internet explorers and digital entrepreneurs. The third step uses a stochastic frontier approach to investigate whether these profiles increase the economic efficiency of informal firms. Our findings suggest that while the most advanced uses of mobile phones have an incremental impact on sales efficiency, the potential for improvement remains limited. Only networkers' coordination uses show a significant impact on value added and profit, while the ways in which Internet explorers and digital entrepreneurs use a mobile phone have only a limited impact.
Catty, bitchy, queen bee or sister? A review of competition among women in organizations from a paradoxical‐coopetition perspective

Published: January 2023

AbstractWomen in organizations must grapple with a double‐bind stemming from conflicting expectations toward them to exhibit both competition (per workplace norms) and cooperation (per societal gender‐specific norms), and they often suffer a backlash for conforming to one expectation at the expense of the other. Similarly, different streams of literature offer contrasting accounts of women's competitive attitudes and behavior. This systematic review is the first attempt to integrate research on competition among women in organizations across research disciplines to gain a nuanced insight into the pervasiveness, causes, dynamics, and manifestations of this phenomenon. In doing so, we draw on the wide research pertaining to women's intra‐gender competitive attitudes and behavior in structured competition within organizations, and on relevant intersectionality research that looks at diverse groups of women. We synthesize the research to suggest a paradoxical framework of coopetition (competitive‐cooperation) that can guide future theoretical insights and research directions, along with practical organizational tools, to effectively deal with the tension and inequality that result from paradoxical expectations and formulate important future research directions.

ABSTRACTPleistocene faunal assemblages are often highly fragmented, hindering taxonomic identifications and interpretive potentials. In this paper, we apply four different methodologies to morphologically unidentifiable bone fragments from the Neanderthal open‐air site of Salzgitter‐Lebenstedt (Germany). First, we recorded zooarchaeological attributes for all 1362 unidentifiable bones recovered in 1977. Second, we applied zooarchaeology by mass spectrometry (ZooMS) to 761 fragments, and calculated glutamine deamidation values. Third, we assessed the collagen preservation of 30 fragments by near‐infrared spectroscopy (NIR) and, finally, we pretreated 10 bones with high predicted collagen values for radiocarbon dating. All returned dates at, or beyond, the limit of radiocarbon dating, indicating an age of older than 51 000 years ago. The ZooMS faunal spectrum confirms a cold environment, dominated by reindeer, alongside mammoth, horse and bison. The low occurrence of carnivore modifications (1%) contrasts with an abundance of human modifications (23%). Cut marks and marrow fractures were observed across reindeer, horse and bison. The mammoth remains are less well preserved and show a lower degree of human modifications, indicating, perhaps, a different taphonomic history. Overall, this study illustrates the importance of retaining, studying and incorporating the unidentifiable bone fraction to optimize interpretations of site formation and subsistence behaviour at Palaeolithic sites.

Published: January 2023

AbstractHuman–wildlife conflict can cause major declines in wildlife populations and pose a threat to human safety and livelihoods. Large carnivores are among the most conflict‐prone species because they range widely, eat human‐associated foods, and can pose a risk to human safety. Legal harvest of carnivores by licensed hunters is an attractive method to attempt to reduce conflict; however, there is mixed evidence for its effectiveness. We leveraged a unique management project in Ontario, Canada in which a new spring American black bear (Ursus americanus) hunting season was implemented in selected wildlife management units in addition to the existing fall season. We examined human–bear interactions and incidents before (2012 and 2013) and after (2014 and 2015) this implementation in treatment and control areas. Further, using data from 2004–2019, we examined the longer‐term patterns of human–bear interactions and incidents before and after this management project when a spring season was implemented throughout the entire province beginning in 2016. Harvest increased significantly upon the implementation of the spring season in selected units, but there was no concomitant reduction in interactions or incidents, and these were higher in areas with the new spring season relative to control areas. Human–bear interactions, incidents, and harvest were strongly related to the availability of natural foods in all analyses. Regulated, presumably sustainable harvest was ineffective at reducing human–bear interactions and incidents in the near‐term and might have increased both. Our results support a long history of research showing that natural food availability is a primary driver of human–wildlife conflict. Programs promoting coexistence between people and wildlife, including education, capacity building, and management of unnatural food sources are likely to be the most successful at reducing conflicts between people and bears.
De Gruyter name change policy: Case study for learned publishing
Authors: Smith Christene , Schönwetter Charlott , Smith Christopher 
Published: January 2023

Key points
A name change policy ensures that any academic author wishing to change their name can do so ‘silently’ and without it being announced. This case study shares how De Gruyter designed and implemented a policy with a view to sharing its learning and experience with the wider publishing community.
While anyone can take advantage of a name change policy, they are particularly important for transitioning scholars who want to change their name without being publicly ‘outed’ by the traditional revisions process.
Academic publishers are increasingly seeing the importance of implementing name change policies. De Gruyter, alongside many others in the United States and Europe, are developing policies following COPE guidelines.
The impetus for De Gruyter's name change policy came from a group of proactive employees who formed a committee to drive the idea forward. Over 18 months, the group researched best practice and engaged all parts of the business to build understanding, cooperation and support for the initiative.
Introduced on 6th October 2022, De Gruyter's policy provides any academic author wishing to change their name with a ‘blind update’ of their name across all of their De Gruyter‐published material. The case study goes on to outline the personal learning points of the project leader, Dr. Christene Smith.

Published: January 2023

AbstractAn optical limiter (OL) is a nonlinear device that protects sensitive photodetectors or human eyes from high‐intensity illumination. However, current OLs have low open‐state transmittance and a limited turndown ratio in some cases. In this study, first it is demonstrated that combining the insulator‐to‐metal transition (IMT) of vanadium dioxide (VO2) with anti‐reflection layers can enable both high and broadband open‐state transmittance (>−0.9 dB at the peak wavelength) while preserving a large turndown ratio (>21.8 dB). Furthermore, optothermal simulation is conducted to analyze the performance of the VO2 OL under ultrafast laser irradiation. The result reveals that IMT of the VO2 OL occurs at 0.23 µs when the incident laser intensity is 90 kW cm−2. These benefits offer a promising alternative to OLs in technologies ranging from sensor protection to human eye defense.

Published: January 2023

AbstractDistributed RF systems are referred to as the fundamental structure for future wireless communication and sensors. To enable wideband coherent operation, synchronization across the distributed systems with massive parallel absolute time delay (ATD) measurements up to sub‐picosecond precision should be implemented. Traditional ways to achieve precise ATD measurements usually rely on probe signals with broad bandwidth, while that of RF systems is limited. Although an all‐optical solution has high precision, it is complex and not compatible with RF systems. Microwave photonics, which combines the merits of RF and photonics, potentially provides a low‐cost and high‐precision solution that can be deployed in existing RF systems. Here, ATD measurement with sub‐picosecond precision directly over an existing radio over free‐space optical (RoFSO) link, requiring no additional hardware beyond the link, is achieved. The bandwidth of the system is only 10 MHz, while the measurement results meet well with those obtained by optical combs. The measurement errors caused by atmospheric turbulence are well suppressed by a dynamic Kalman filter. The RoFSO links can be stabilized in a closed‐loop measurement. The standard deviation of the timing jitter is 0.28 ps, and the Allan variance is around 1.9 × 10−19 @ 1000 s, which is sufficient to synchronize millimeter‐wave signals.

AbstractThe corrosion behavior and corrosion products of three zinc alloy‐coated steel substrates with different Al and Mg contents such as hot‐dip galvanized steel (HDG), Zn–Al‐coated steel (ZA), and Zn–Al–Mg‐coated steel (ZM) substrates were investigated during 168 h of immersion in 0.1 M NaCl solution. The characteristics and morphology of corrosion products on all the substrates formed during exposure to electrolyte solution were observed by X‐ray diffraction, X‐ray photoelectron spectroscopy, and scanning electron microscopy/energy‐dispersive X‐ray spectroscopy. Their electrochemical behavior was investigated by open‐circuit potential, polarization curves, and electrochemical impedance spectroscopy. The addition of Al and Mg alloying elements affected the corrosion mechanism as well as the anticorrosion properties. The main crystalline corrosion products on the HDG surface were simonkolleite and zincite, while the ZnAl hydrotalcite was identified as the main corrosion product on ZA and ZM surfaces. The corrosion resistance of ZA and ZM substrates was improved compared to the HDG substrate due to the enhanced adhesion of the corrosion product layer.

Published: January 2023

AbstractHigh‐temperature oxidation behavior of IBN‐1 alloy, Ni–Cr thermally sprayed coating, Ni–Cr thermally sprayed coating with surface shot peening and grinding treatment in supercritical water have been investigated at 650°C under 25 MPa. The oxidation kinetics of IBN‐1 steel follows the parabolic law. Compared with substrate metals, the oxidation resistance of IBN‐1 steel with the three kinds of Ni–Cr coating treatment has been greatly improved due to the formation of Cr‐rich oxide and the oxidation kinetics deviated from the parabolic behavior seriously. The deviation may be attributed to differences in the oxide phase with an increase in oxidation time. Furthermore, the difference in oxidation rate among different Ni–Cr coating surface treatment processes can be observed. The related mechanism has been discussed.

Published: January 2023

AbstractUsing the M13 phage display, a series of 7‐ and 12‐mer peptides which interact with new sulfobetaine hydrogels are identified. Two peptides each from the 7‐ and 12‐mer peptide libraries bind to the new sulfobetaine hydrogels with high affinity compared to the wild‐type phage lacking a dedicated hydrogel binding peptide. This is the first report of peptides binding to zwitterionic sulfobetaine hydrogels and the study therefore opens up the pathway toward new phage or peptide/hydrogel hybrids with high application potential.
