Purpose
Student mental well-being is a matter of increasing concern on university campuses around the world. Social, psychological, academic and career aspects of graduate learning are enriched through peer mentorship. Peer-mentoring experiences and the impacts of these relationships on the mental well-being of graduate students remain underexplored in the scholarship of teaching and learning. The purpose of this study was to explore how engagement in formal and informal peer mentorship, as described by students across four academic disciplines, impacts the social connectedness and well-being of graduate students.

Design/methodology/approach
A convergent mixed methods research design was used, with quantitative and qualitative data gathered in parallel to gain a comprehensive, corroborated and integrated understanding of graduate students’ perspectives and experiences with peer mentorship. Online survey and interview data were collected from graduate thesis-based master’s EdD and PhD students in education, medicine, nursing and social work. The data were analyzed using descriptive statistics and thematic analysis.

Findings
The authors found a commonality of graduate student experiences across disciplines with respect to the diverse psychosocial impacts of graduate peer mentorship. Peer-mentoring relationships offered mentees emotional support, motivation and a sense of community and offered mentors opportunities for self-development and gratification.

Originality/value
This research is unique in its in-depth exploration of the interdisciplinary perspectives and experiences of graduate students from Education, Nursing, Medicine and Social Work. While further research is needed to explore the implementation of structural approaches to support the development of peer-mentoring relationships in graduate education, the multidisciplinary focus and depth and breadth of this inquiry suggest the potential transferability of the study findings to other disciplines and academic settings. The findings from this study further highlight the need for strategic activation of existing program resources to foster greater connectedness and well-being among graduate students.
INFINITI HR – professional employer organizations
Authors: White Susan , Hallows Karen 
Published: March 2021

Theoretical basis
Students need to know basic capital budgeting techniques to value INFINITI and its competitors. Issues include how to: handle taxes in a discounted cash flow analysis when valuing an S Corp. where incentives depend on current (known) and future (unknown) tax provisions; value a firm using comparable multiples analysis and transactions data; assess the costs and benefits of acquiring a firm versus being acquired; and analyze an industry and perform a ratio and financial statement analysis.

Research methodology
The case information was obtained through interviews with co-founder Mark Schwaiger. In addition, the authors researched industry and comparable company data, along with current events relating to the professional employer organization (PEO). Financial data was obtained from the owners and competitor data was obtained from Thomson One and Bloomberg.

Case overview/synopsis
INFINITI HR was a PEO providing comprehensive human resources to their clients. Co-founders Scott Smrkovski and Mark Schwaiger were at a crossroads at the end of 2015 trying to determine the best course of action to take with their company to grow and prosper. One option was for INFINITI to be acquired by a larger company and the second option was for INFINITI acquire a smaller company. In this case, students have the opportunity to do a financial analysis and evaluation of INFINITI and its competitors to determine which option is the best.

Complexity academic level
This case is intended for an advanced undergraduate or an MBA corporate finance class.
Telemedicine co‐design and value co‐creation in public health care
Authors: Leite Higor , Hodgkinson Ian R. 
Published: March 2021

AbstractCOVID‐19 has presented significant challenges for public healthcare systems across the globe. The critical challenge for public healthcare organisations is to provide effective health care to patients, while simultaneously keeping frontline staff safe. Telemedicine has emerged as a prominent service intervention to this end. Telemedicine integrates technologies into medical practices to alleviate the need for face‐to‐face interactions through video consultations. The study explores how physicians and patients can, together, co‐create service value both within the telemedicine ecosystem and under crisis. Secondary qualitative data from physicians and patients active on Twitter and from across multiple countries are used to this end. Thematic analysis reveals seven themes that inform a new integrative telemedicine value co‐creation framework, which provides a platform for inclusive, equitable, and sustainable telemedicine services. The study provides a new understanding of the service triad ‒ telemedicine co‐design, value co‐creation, and service improvement ‒ highlighting the roles of co‐design and value co‐creation for public health care under crises.
Determining the chronological sequence of inks deposited with different writing and printing tools using ion beam analysis

Published: March 2021

AbstractDetermining the sequence of inks in a questioned document is important in forensic science. Conventional and micro beam‐based ion beam analysis using Rutherford backscattering spectrometry (RBS) and particle‐induced X‐ray emission were employed to study the depth distribution of chemical elements in plain paper and inks/toner deposited by different pens as well as inkjet and laser printers. Composition depth profiling with high lateral resolution was performed with focus on areas where two different coloring agents overlapped. We identify under which conditions the sequence of inks deposited can be reconstructed, analyzing the continuity of characteristic contributions to the obtained signals, with a focus on the depth‐resolved RBS data. The order of deposition was correctly determined for combinations of two different laser printers and in certain cases for pens. Results indicate a potential for analysis, depending on the composition of staining agent, that is, in particular if heavy species are present in sufficiently high concentration. In such cases, also characters obscured or modified by an agent of different composition can be revealed. Changing the probing depth by modifying the beam energy could yield additional information.
Distinguishing between recent balancing selection and incomplete sweep using deep neural networks
Authors: Isildak Ulas , Stella Alessandro , Fumagalli Matteo 
Published: March 2021

AbstractBalancing selection is an important adaptive mechanism underpinning a wide range of phenotypes. Despite its relevance, the detection of recent balancing selection from genomic data is challenging as its signatures are qualitatively similar to those left by ongoing positive selection. In this study, we developed and implemented two deep neural networks and tested their performance to predict loci under recent selection, either due to balancing selection or incomplete sweep, from population genomic data. Specifically, we generated forward‐in‐time simulations to train and test an artificial neural network (ANN) and a convolutional neural network (CNN). ANN received as input multiple summary statistics calculated on the locus of interest, while CNN was applied directly on the matrix of haplotypes. We found that both architectures have high accuracy to identify loci under recent selection. CNN generally outperformed ANN to distinguish between signals of balancing selection and incomplete sweep and was less affected by incorrect training data. We deployed both trained networks on neutral genomic regions in European populations and demonstrated a lower false‐positive rate for CNN than ANN. We finally deployed CNN within the MEFV gene region and identified several common variants predicted to be under incomplete sweep in a European population. Notably, two of these variants are functional changes and could modulate susceptibility to familial Mediterranean fever, possibly as a consequence of past adaptation to pathogens. In conclusion, deep neural networks were able to characterize signals of selection on intermediate frequency variants, an analysis currently inaccessible by commonly used strategies.

Published: March 2021

AbstractBackgroundMidwifery continuity of care models are the only health system intervention associated with both a reduction in preterm birth (PTB) and an improvement in perinatal survival; however, questions remain about the mechanisms by which such positive outcomes are achieved. We aimed to uncover theories of change by which we can postulate how and why continuity of midwifery care models might affect PTB.MethodsWe followed Pawson's guidance for conducting a realist review and performed a comprehensive search to identify existing literature exploring the impact of continuity models on PTB in all pregnant women. A realist methodology was used to uncover the context (C), mechanisms (M), and outcomes (O) and to develop a group of CMO configurations to illuminate middle‐range theories.ResultsEleven papers were included from a wide variety of settings in the United Kingdom, Australia, and the United States. The majority of study participants had low socioeconomic status or social risk factors and received diverse models of midwifery continuity of care. Three themes—woman‐midwife partnership, maternity pathways and processes, and system resources—encompassed ten CMO configurations. Building relationships, trust, confidence, and advocacy resulted in women feeling safer, less stressed, and more secure and respected, and encouraged them to access and engage in antenatal care with more opportunities for early prevention and diagnosis of complications, which facilitated effective management when compliance to guidelines was ensured. Organizational infrastructure, innovative partnerships, and robust community systems are crucial to overcome barriers, address women's complex needs, ensure quality of care, and reduce PTB risk.ConclusionsPregnant women living in different contexts in the United Kingdom, Australia, and the United States at low and mixed risk of complications and with low socioeconomic status or social risk factors experienced continuity models in similar ways, and similar underlying mechanisms may have influenced PTB outcomes. Further research is required to understand how continuity models may influence behavioral change, physiological stress levels, ethnic disparities in PTB and care coordination, and navigation of health services.

AbstractMore than 1 year after the outbreak of COVID‐19, Canadian fruit and vegetable markets continue to adjust to the evolving landscape. In this article, we focus on three key measures of input and output market performance that serve as indicators of the stability of fruit and vegetable markets in Canada in the medium‐term, and offer some insight for how these markets will continue to adjust in the longer run. Specifically, we use data to highlight the most recent trends in (1) the production and aggregate movement for major fruit and vegetable crops in the United States and Canada, (2) labor supply and immigration visa patterns, and (3) U.S.–Canada trade patterns for fruits and vegetables. We provide evidence that the fresh produce supply chain in Canada, and for markets in their largest trade partner in the United States, has remained relatively robust.

AbstractDetermining metapopulation persistence requires understanding both demographic rates and patch connectivity. Persistence is well understood in theory but has proved challenging to test empirically for marine and other species with high connectivity that precludes classic colonisation–extinction dynamics. Here, we assessed persistence for a yellowtail anemonefish (Amphiprion clarkii) metapopulation using 7 years of annual sampling data along 30 km of coastline. We carefully accounted for uncertainty in demographic rates. Despite stable population abundances through time and sufficient production of surviving offspring for replacement, the pattern of connectivity made the metapopulation unlikely to persist in isolation and reliant on immigrants from outside habitat. To persist in isolation, the metapopulation would need higher fecundity or to retain essentially all recruits produced. This assessment of persistence in a marine metapopulation shows that stable abundance alone does not indicate persistence, emphasising the necessity of assessing both demographic and connectivity processes to understand metapopulation dynamics.
Stable isotope signatures in historic harbor seal bone link food web‐assimilated carbon and nitrogen resources to a century of environmental change

AbstractAnthropogenic climate change will impact nutrient cycles, primary production, and ecosystem structure in the world's oceans, although considerable uncertainty exists regarding the magnitude and spatial variability of these changes. Understanding how regional‐scale ocean conditions control nutrient availability and ultimately nutrient assimilation into food webs will inform how marine resources will change in response to climate. To evaluate how ocean conditions influence the assimilation of nitrogen and carbon into coastal marine food webs, we applied a novel dimension reduction analysis to a century of newly acquired molecular isotope data derived from historic harbor seal bone specimens. By measuring bulk δ13C and δ15N values of source amino acids of these top predators from 1928 to 2014, we derive indices of primary production and nitrogen resources that are assimilated into food webs. We determined coastal food webs responded to climate regimes, coastal upwelling, and freshwater discharge, yet the strength of responses to individual drivers varied across the northeast Pacific. Indices of primary production and nitrogen availability in the Gulf of Alaska were dependent on regional climate indices (i.e., North Pacific Gyre Oscillation) and upwelling. In contrast, the coastal Washington and Salish Sea food webs were associated with local indices of freshwater discharge. For some regions (eastern Bering Sea, northern Gulf of Alaska) food web‐assimilated production was coupled with nitrogen sources; however, other regions demonstrated no production‐nitrogen coupling (Salish Sea). Temporal patterns of environmental indices and isotopic data from Washington state varied about the long‐term mean with no directional trend. Data from the Gulf of Alaska, however, showed below average harbor seal δ13C values and above average ocean conditions since 1975, indicating a change in primary production in recent decades. Altogether, these findings demonstrate stable isotope data can provide useful indices of nitrogen resources and phytoplankton dynamics specific to what is assimilated by food webs.

Published: March 2021

AbstractPlant–pollinator interactions are highly relevant to society as many crops important for humans are animal pollinated. However, changes in climate and land use may put such interacting patterns at risk by disrupting the occurrences between pollinators and the plants they pollinate. Here, we analyse how the co‐occurrence patterns between bat pollinators and 126 plant species they pollinate may be disrupted given changes in climate and land use, and we forecast relevant changes of the current bat–plant co‐occurrence distribution patterns for the near future. We predict under RCP8.5 21% of the territory will experience a loss of bat species richness, plants with C3 metabolism are predicted to reduce their area of distribution by 6.5%, CAM species are predicted to increase their potential area of distribution up to 1% and phanerophytes are predicted to have a 14% reduction in their distribution. The potential bat–plant interactions are predicted to decrease from an average of 47.1 co‐occurring bat–plant pairs in the present to 34.1 in the pessimistic scenario. The overall changes in suitable environmental conditions for bats and the plant species they pollinate may disrupt the current bat–plant co‐occurrence network and will likely put at risk the pollination services bat species provide.

AbstractChitin deacetylases (CDAs) convert chitin into chitosan and play crucial roles in the insect biological processes, including growth and development. In this study, two CDA‐encoding genes, HcCDA1 and HcCDA4, were identified from Hyphantria cunea. Conserved Domain Database for HcCDA1 identified a chitin‐binding peritrophin‐A domain (ChBD), a low‐density lipoprotein receptor class A domain (LDLa), and a putative CDA‐like catalytic domain (CDA), whereas HcCDA4 lacked the LDLa domain. Phylogenetic comparison with other insect CDAs revealed that HcCDA1 belonged to the insect group I CDA and HcCDA4 belonged to group III. qRT‐PCR results showed that HcCDA1 and HcCDA4 were more highly expressed in newly moulted 5th‐instar larvae, and HcCDA1 was highly expressed in the integument, whereas HcCDA4 was abundantly transcribed in the integument and hindgut. Western blot revealed that the expression of HcCDA1 and HcCDA4 in translational levels were consistent with the transcription. Double‐stranded RNA injection of HcCDA1 and HcCDA4 into H. cunea larvae significantly reduced HcCDA transcript levels, resulted in larval–pupal moulting difficulty, and produced high larval mortality. These results demonstrate important contributions of HcCDA1 and HcCDA4 to insect moulting and development and provide potential new targets for designing effective double‐stranded RNA‐based pesticides to protect crops.
The relative number of anti‐takeover provisions and the market for corporate control

Published: March 2021

AbstractUsing propensity score matching, we provide new evidence of a nonmonotonic relation between the number of anti‐takeover provisions (ATPs) a firm adopts, relative to peer‐matched firms, and takeover likelihood. Firms with either a relatively low or high number of ATPs are significantly less likely to be a takeover target. We argue that this outcome is a result of the expected benefits versus costs of targeting firms in the left and right tails of the peer‐matched ATP distribution. In particular, firms in the left tail with a relatively small number of ATPs tend to have high market valuations, indicative of management optimizing shareholder welfare and hence being less concerned about the threat of a takeover. Overall, our findings have important implications for both corporate and regulatory policy.

Published: March 2021

AbstractBackgroundPotentially inappropriate medication (PIM) use is a risk factor for hospitalization and mortality. However, there were few studies focusing on the impact of provider type on PIM use.ObjectiveWe aimed to estimate the initial and refill PIM prescribing rate for physician visits and nurse practitioner (NP) visits and the impact of provider type on PIM prescribing.Research DesignWe used 100% Texas Medicare data to define physician visits and NP visits in 2016. The rate of visits with a PIM prescription from the same provider was measured, distinguishing between initial and refill prescription to estimate the PIM rate and adjusted odds ratio (OR) by provider type.ResultsThere were 24.1 per 1000 visits with a prescription for a PIM: 9.0 per 1000 visits for an initial PIM and 15.1 per 1000 visits for a refill PIM. A visit to an NP was less likely to result in an initial (OR = 0.74, 95% confidence interval [CI] = 0.70–0.79) or refill (OR = 0.54, 95% CI = 0.51–0.57) PIM. The association of lower odds of receiving a prescription for an initial PIM from an NP was substantially stronger among black enrollees than white enrollees (OR = 0.44, 95%CI = 0.30–0.65 for blacks and OR = 0.73, 95%CI = 0.68–0.78 for white enrollees). The association of an NP provider with lower odds of receiving a PIM refill was more pronounced in older patients and in those with more comorbidities.ConclusionsNPs prescribed fewer initial PIMs and were less likely to refill a PIM after an outpatient visit than physicians. The lower odds of receiving PIMs during an NP visit varied by age, race/ethnicity, rurality, and number of comorbidities.

AbstractObjectivesTo explore the relationship between parents' practices and the oral health‐related quality of life of children according to the child's point of view.MethodsIt is a cross‐sectional study with all children (response rate 75.6 percent, n = 329) from fourth grade of Elementary School to the third grade of High School in 2016 in a small city of southern Brazil. Oral health related quality of life was measured using the oral impact on daily performances (OIDP) using the prevalence of any impact as outcome (OIDP score > 0). Seven parenting practices were evaluated by the inventory of parenting Styles for both father and mother. Logistic regression models were fitted to estimate the association of each parenting practice with OIDP score > 0, and adjusted by sex, age, family equivalent income, mother and father's educational level.ResultsAbout 55.3 percent of the children had at least one impact on daily performances. Respectively, the parenting practices with the highest and lowest percentage for both parents' risk behavior was physical abuse (28.8 percent) and negative monitoring (7.8 percent), while families in which both parents' risk behavior for negligence was 14.7 percent. In the adjusted models, families in which both parents' risk behavior on negligence [odds ratio (OR) = 2.74, 95% confidence intervals (95%CI): 11.27–6.23] and physical abuse (OR = 2.16, 95%CI: 1.13–4.19) and (lack of) positive monitoring (OR = 2.99, 95%CI: 1.32–7.40) had a greater impact on daily life compared to those in which no parents' had risk behavior.ConclusionsHaving any impact on OIDP was associated with negligence, physical abuse, and lack of monitoring among children and adolescents.
