AbstractSnow depth on the interior of Tibetan Plateau (TP) in state-of-the-art reanalysis products is almost an order of magnitude higher than observed. This huge bias stems primarily from excessive snowfall, but inappropriate process representation of shallow snow also causes excessive snow depth and snow cover. This study investigated the issue with respect to the parameterization of fresh snow albedo. The characteristics of TP snowfall were investigated using ground truth data. Snow in the interior of the TP is usually only some centimeters in depth. The albedo of fresh snow depends on snow depth, and is frequently less than 0.4. Such low albedo values contrast with the high values (~0.8) used in the existing snow schemes of land surface models. The SNICAR radiative transfer model can reproduce the observations that fresh shallow snow has a low albedo value, based on which a fresh snow albedo scheme was derived in this study. Finally, the impact of the fresh snow albedo on snow ablation was examined at 45 meteorological stations on TP using the land surface model Noah-MP which incorporated the new scheme. Allowing albedo to change with snow depth can produce quite realistic snow depths compared with observations. In contrast, the typically assumed fresh snow albedo of 0.82 leads to too large snow depths in the snow ablation period averaged across 45 stations. The shallow snow transparency impact on snow ablation is therefore particularly important in the TP interior, where snow is rather thin and radiation is strong.
Does Trade Liberalisation Policy Enhance Performance of Non-Oil Export Trade in Nigeria?

Published: March 2020

Decades after the trade liberalisation policy shift, poor performance problem of non-oil export in Nigeria (a net-oil exporting economy) persists. Against this backdrop, and given the lack of analytical depth among Nigerian-specific studies, this study empirically provided answer to the question of whether trade liberalisation policy enhances non-oil export trade in Nigeria. The study adopted an Autoregressive Distributed Lag model approach to the analysis of the impact of trade liberalisation policy on non-oil export trade. Evidence provided support for trade liberalisation policy as the growth driver for non-oil export, a sector that exports more but earns little in terms of revenue. As a result, the study recommends a well thought-out public–private partnership arrangement for the efficiency of the private sector (a major player in non-oil export trade), to optimally harness the benefits of liberalisation in Nigeria’s non-oil trade sub-sector.

Preface to the Special Issue on Human Factors and Advanced Vehicle Automation: Of Benefits, Barriers, and Bridges to Safe and Effective Implementation
Authors: Horrey William J. , Lee John D. 
Published: March 2020

Objective The aim of this special issue is to bring together the latest research related to driver interaction with various types of vehicle automation. Background Vehicle technology has undergone significant progress over the past decade, bringing new support features that can assist the driver and take on more and more of the driving responsibilities. Method This issue is comprised of eight articles from international research teams, focusing on different types of automation and different user populations, including driver support features through to highly automated driving systems. Results The papers comprising this special issue are clustered into three categories: (a) experimental studies of driver interactions with advanced vehicle technologies; (b) analysis of existing data sources; and (c) emerging human factors issues. Studies of currently available and pending systems highlight some of the human factors challenges associated with the driver–system interaction that are likely to become more prominent in the near future. Moreover, studies of more nascent concepts (i.e., those that are still a long way from production vehicles) underscore many attitudes, perceptions, and concerns that will need to be considered as these technologies progress. Conclusions Collectively, the papers comprising this special issue help fill some gaps in our knowledge. More importantly, they continue to help us identify and articulate some of the important and potential human factors barriers, design considerations, and research needs as these technologies become more ubiquitous.

Published: March 2020

Objective We examine whether surgical teams can handle changes in task requirements better when their formal leader and strategic core role holder—that is, the main surgeon—is central to team coordination. Background Evidence regarding the benefits of shared leadership for managing complex tasks is divided. We tested whether a strategic core role holder’s centrality in team coordination helps teams to handle different types of task complexity. Method We observed coordination as specific leadership behavior in 30 surgical teams during real-life operations. To assess the strategic core role holder’s coordination centrality, we conducted social network analyses. Task complexity (i.e., surgical difficulty and unexpected events) and surgical goal attainment were rated in a questionnaire. Results In the critical operation phase, surgical difficulty impaired goal attainment when the strategic core role holder’s coordination centrality was low, while this effect was nonsignificant when his/her coordination centrality was high. Unexpected events had a negative effect on surgical goal attainment. However, coordination centrality of the strategic core role holder could not help manage unexpected events. Conclusion The results indicate that shared leadership is not beneficial when teams face surgical difficulty during the critical operation phase. In this situation, team coordination should rather be centralized around the strategic core role holder. Contrarily, when unexpected events occur, centralizing team coordination around a single leader does not seem to be beneficial for goal attainment. Application Leaders and team members should be aware of the importance of distributing leadership differently when it comes to managing different types of task complexity.
A Virtuous Appraisal of Heritable Genome Editing
Authors: Reilly Christopher M. 
Published: March 2020

The ethics of heritable genome editing (HGE), or germline engineering, are currently being debated vigorously among scientists and bioethicists, and the Catholic Church has declared the procedure to be morally illicit. While these judgments are based mostly on the justice and consequences of the act, a fruitful approach is to consider HGE from the perspective of the virtuous Christian. This article examines participation in HGE according to the virtues of charity, justice, hope, faith, fortitude, temperance, and prudence. HGE does not appear to be consonant with the virtuous life of a Christian person. Summary: The article evaluates heritable genome editing (HGE or genetic engineering of embryos) according to the Christian virtues of charity, justice, hope, faith, fortitude, temperance, and prudence. HGE does not seem to be consonant with the virtuous life of a Christian person.
What Can a Jump Tell Us About Elbow Injuries in Professional Baseball Pitchers?
Authors: Mayberry John , Mullen Scott , Murayama Scott 
Published: March 2020

Background: The incidence rate of elbow injuries has been rising in recent years among professional baseball pitchers. Determining valid screening procedures that allow practitioners to identify pitchers at an increased risk of such injuries is therefore of critical importance. Purpose: To validate the use of countermovement jump (CMJ) tests as a diagnostic tool for pitcher conditioning. Study Design: Case-control study; Level of evidence, 3. Methods: More than 500 pitchers at a single professional baseball organization performed preseason CMJ assessments on a force plate before the 2013 to 2018 seasons. Three measurements were extracted from ground-reaction force data during the test: eccentric rate of force development (ERFD), average vertical concentric force (AVCF), and concentric vertical impulse (CVI). Athletic trainers at the organization collected detailed information on elbow and shoulder injury rates as well as workload (pitch count) throughout the rest of the season. Poisson regression models were fit to investigate the dependency of injury rates on CMJ test performance. Results: ERFD, CVI, and AVCF were all significant predictors of elbow injury risk after accounting for pitcher age, weight, and workload. The analysis identified 3 specific indicators of heightened risk based on the results of a CMJ scan: low ERFD, a combination of low AVCF and high CVI, and a combination of high AVCF and low CVI. In contrast, shoulder injury risk was roughly independent of all 3 CMJ test measurements. Conclusion: This study supports the hypothesis of the entire kinetic chain’s involvement in pitching by establishing a link between CMJ test performance and elbow injury risk in professional baseball pitchers. CMJ assessment may be a powerful addition to injury risk alert and prevention protocols. Pitchers in high-risk groups can be prescribed specific exercise plans to improve movement imbalances.

Published: March 2020

Background: Patients who undergo hip arthroscopy inevitably experience pain postoperatively; however, the efficacy and safety of adjunct analgesia to prevent or reduce pain are not well-understood. Purpose: To perform a comprehensive qualitative synthesis of available randomized controlled trials evaluating the effect of adjunct analgesia on postoperative (1) pain, (2) opioid use, and (3) length of stay (LOS) in patients undergoing hip arthroscopy. Study Design: Systematic review. Methods: PubMed, OVID/MEDLINE, and Cochrane Controlled Register of Trials were queried for studies pertaining to analgesia interventions for patients undergoing hip arthroscopy. Two authors independently assessed article bias and eligibility. Data pertaining to changes in pain scores, additional analgesia requirements, length of hospital stay, and complications were extracted and qualitatively reported. Network meta-analyses were constructed to depict mean pain, opioid use, and LOS among the 3 analgesia categories (blocks, local infiltration analgesia, and celecoxib). Results: Fourteen level 1 studies were included; 12 (85.7%) reported pain reductions in the immediate and perioperative period after hip arthroscopy. Of the 7 studies that assessed an intervention (2 celecoxib, 1 fascia iliaca block, 1 lumbar plexus block, 1 femoral nerve block, 1 intra-articular bupivacaine, 1 extracapsular bupivacaine) versus placebo, more than half reported that patients who received an intervention consumed significantly fewer opioids postoperatively than patients who received placebo (lowest P value = .0006). Of the same 7 studies, 2 reported significantly shortened LOS with interventions, while 4 reported no statistically significant difference in LOS and 1 did not report LOS as an outcome. Conclusion: The majority of studies concerning adjunct analgesia for patients undergoing hip arthroscopy suggest benefits in pain reduction early in the postoperative period. There is mild evidence that adjunct analgesia reduces postoperative opioid use and currently inconclusive evidence that it reduces length of hospital stay. Furthermore, it appears that local infiltration analgesia may provide the greatest benefits in reductions in pain and opioid consumption. We recommend the use of adjunct analgesia in appropriately selected patients undergoing hip arthroscopy without contraindication who are at a high risk of severe postoperative pain.

Published: March 2020

Background: Frailty and palliative performance scores are 2 markers used in the measurement of functional decline in oncology and hospice care. Objective: To evaluate the frailty and palliative performance scores of a long-term care resident community and determine whether frailty and palliative performance scores can predict hospital readmissions (HR) and survivability of the long-term care resident. Methods: One hundred seventy-one long-term care residents from 2 urban facilities were evaluated for functional decline using the Clinical Frailty Scale (CFS) and Palliative Performance Scale (PPS). Sociodemographic, HR, and survival data for 1 year from study initiation were recorded. Results: The 171 long-term care residents, of lower socioeconomic status, primarily Medicare/Medicaid or dual-eligible, evaluated for functional decline using the CFS and PPS, had mean age of 73.1 years, 52.6% female, 94.7% African American, with 18.1% having HR and 87.1% surviving more than a year. There was a negative association between age and HR ( P = .384). Among functional evaluation scales, CFS was positively associated with age ( P = .013) but not PPS ( P = .673). The residents scored 6.0 ± 1.2 on CFS and 52.8 ± 13.2 on PPS (%) with those residents readmitted to hospital having poorer outcomes. Readmission to hospital and survivability of the long-term care resident were both strongly associated with CFS ( P = .001) and PPS ( P = .001). Conclusion: There is a strong association between the 2 markers used in the measurement of functional decline— Frailty measured by CFS and Palliative Performance Score measured by PPS. Frailty and palliative performance scores can strongly predict HR and survivability of the long-term care resident.
Effect of Tourniquet Use During Ankle Fracture Fixation on Wound Healing and Infectious Complications
Authors: Benedick Alex , Rivera Trenton , Vallier Heather A. 
Published: March 2020

Background: Tourniquets are common during extremity surgery; however, effects of tourniquets on complications following ankle fracture surgery have not been well described. The purpose was to evaluate effects of tourniquet usage on wound complications and infections after ankle fracture fixation. Methods: Consecutive patients (N = 903) treated operatively for torsional ankle injury were identified. Patients for whom a tourniquet was used intraoperatively (n = 523) were compared to those without (n = 380). Subgroup analysis included patients possibly sensitive to tissue ischemia (diabetes, obesity, tobacco, age >65 years, and open fracture). Multiple logistic regression analysis was performed. Results: A tourniquet was used in 523 (57.9%) of cases. Overall, 22.9% of patients had open fractures in the group with no tourniquet, vs 11.3% ( P < .001), with no differences in fracture pattern or medical comorbidities, except tobacco use was more frequent in the no tourniquet group (51.9% vs 44.4%, P = .032). No significant differences in complications were noted, including superficial infection (4.2% [no tourniquet] vs 5.2%), deep infection (2.1% vs 2.3%), and wound healing problems (6.3% vs 4.0%). Similarly, subgroup analysis failed to reveal any differences in complications based on diabetes, obesity, tobacco use, age, or open fracture. However, patients with open fractures or diabetes were more likely to experience deep infection (OR 3.73, P = .014, and OR 4.01, P = .021, respectively). Conclusions: Tourniquet use did not affect rates of wound healing problems or infections. However, patients with open fractures or diabetes were at higher risk. Tissue ischemia produced by a tourniquet did not appear to result in more wound healing or infectious complications. Level of Evidence: Level III, prognostic, comparative study
Perceived social stigmatisation of gambling disorders and coping with stigma
Authors: Dąbrowska Katarzyna , Wieczorek Łukasz 
Published: March 2020

Aim: This study concerns perceived social stigmatisation of gambling disorder and its determinants, the self-perceptions of people with gambling disorder (self-stigma) and how they cope with stigma. Design: In total, 30 interviews with persons with gambling disorder and 60 with professionals were conducted. Selective sampling procedures were employed in the recruitment phase. In the case of professionals, the inclusion criteria were employment in facilities where treatment of gambling disorder is offered, and profession. For people with gambling disorder, the criterion was a diagnosis confirmed by a psychiatrist. Results: Elements revealed in past research on stigma-creation processes were reflected in respondents’ statements. The type of gambling, the occurrence of negative consequences, the possibility of hiding, personal responsibility, social status and contact with stigmatised populations are perceived determinants of problem gamblers’ stigmatisation. Gambling disorder sufferers experience anxiety associated with the possibility of rejection and a fear related to their condition being revealed to others. Various manifestations of cognitive distancing and hiding were coping mechanisms identified in the study. Conclusions: People with gambling disorder experience anxiety associated with the possibility of rejection, and they often conceal their disorder, which may hinder their treatment. Therefore the issue of stigma should be addressed in therapy.
“It’s like being stuck on an unsafe and unpredictable rollercoaster”: Experiencing substance use problems in a partner
Authors: Weimand Bente M , Birkeland Bente , Ruud Torleif , Høie Magnhild M 
Published: March 2020

Living with a partner with substance abuse problems may induce strains in an individual’s everyday life, including poor health, disrupted family life, and social isolation; this may lead to dropping out of education or work, a lack of safety and support, and facing various dilemmas and stigma. Aim: The purpose of this study was to explore these partners’ everyday life experiences, including their parental roles. Method: A qualitative design comprising qualitative interviews with ten partners and ex-partners was performed, and a thematic analysis was used. Results: The findings demonstrated that sharing their lives, including parenthood, with a partner with substance use problems affected every aspect of the participants’ lives, and entailed being influenced by their partner’s ups and downs. The overall theme, “being stuck on an unsafe and unpredictable rollercoaster”, is explored through three themes: “dilemmas, stigma, and shame”, “lack of safety, security, and support,” and “searching for hope and meaning.” Conclusion: As a result of the negative impact of their circumstances on their everyday lives, these individuals need support to handle the challenges that they face, but often find it difficult to ask for help. Peer support groups seemed helpful in enabling them to find ways out of their situation.
Lateral-Only Kirschner-Wire Fixation of Type-3 Supracondylar Humerus Fractures in Children with a Special Attention to Technical Issues
Authors: Hannonen J. , Pokka T. , Serlo W. , Sinikumpu J.-J. 
Published: March 2020

Background and Aims: Lateral-only Kirschner-wire pinning of supracondylar humerus fracture is superior in avoiding surgery-related ulnar nerve injury. Their disadvantageous effects on stability may be a consequence of inappropriate surgical techniques. We analyzed whether the surgeon’s preference for lateral-only fixation is associated with his or her orthopedic competence. We also analyzed the surgical technique–related risk factors of redisplacement. Materials and Methods: All children, aged <16 years, with a distal humerus fracture in 2000–2009 were preliminary included (N = 861). Altogether, 24 of the 165 type-3 supracondylar fractures were operated by lateral-only pinning. Loss of reduction in the follow-up was the main outcome, while the close characteristics of the surgical technique and treating surgeon’s orthopedic competence were the explanatory variables. Results: Orthopedic surgeons used lateral-only method in 23.5% of the type-3 fractures (N = 16/68), and other surgeons in 8.2% (N = 8/97)(difference = 15.3%, 95% confidence interval = 4.6%–27.6%, p = 0.005). One-third of the lateral-only treated fractures (29.2%, 95% confidence interval = 12.6%–51.1%) redisplaced. Lateral-entry pins that crossed at the level of the fracture were associated with failure (87.5%), while no patient with appropriate pin configuration failed (difference = 87.5%, 95% confidence interval = 52.1%–97.8%). A shorter distance (<5 mm) between the entry points of the pins was associated with redisplacement (80% vs. 15.8%, difference = 64.2%, 95% confidence interval = 16.1%–86.9%). Open reduction (p = 0.07), insufficient (<4 mm) bone contact (p = 0.28), monocortical pins (p = 0.569), low diverging angle (p = 0.13) or parallel pins (p = 1.0), residual coronal displacement (p = 1.0), >5° changed Bauman angle (p = 0.11), rotational displacement (p = 0.25), and the experience or specialty of the surgeon were not associated with redisplacement. Conclusion: Lateral-only pins resulted in poor stability in one in three of the patients. Appropriate configuration of the pins was associated with good fracture healing, but crossing the pins at the fracture level and introducing them close to each other were associated with redisplacement. Surgeons with more orthopedic competence selected lateral-only fixation more usually.
