Can Supportive Coaching Behaviors Facilitate Boundary Spanning and Raise Job Satisfaction? An Indirect-Effects Model
Authors: Marrone Jennifer A. , Quigley Narda R. , Prussia Gregory E. , Dienhart John
Published: April 2021

As organizations encounter unpredictable external environments, expectations are changing for managers and team leaders toward providing more facilitative, less directive coaching in order to stimulate more flexibility and adaptability. Prior research has underscored the role of team leader supportive coaching behaviors in reinforcing and growing team member capabilities to work independently from the leader. What is not yet understood, however, is if and how supportive coaching behaviors relate to team member engagement in boundary-spanning behaviors, which are team member efforts to establish and maintain relationships with key parties external to their team. This study examines how team leaders’ supportive coaching of boundary spanning—defined as a set of behaviors that (a) encourages team members to engage in frequent and open collaborations with key parties external to the team and (b) grants team members the latitude to engage external parties in ways the team members deem necessary—relates to team member boundary-spanning behavior and job satisfaction through a motivational pathway. We test a hypothesized indirect-effects model within a field sample of 256 engineering employees working in teams. Results indicate that leaders’ supportive coaching of boundary spanning is positively related to team member boundary-spanning self-efficacy, which in turn is positively related to team member engagement in boundary-spanning behavior for their teams. Also, team members who reported more boundary-spanning behavior experienced greater job satisfaction. The findings have important implications for organizations, team leaders, and team members.
Purpose in the For-Profit Firm: A Review and Framework for Management Research
Authors: George Gerard , Haas Martine R. , McGahan Anita M. , Schillebeeckx Simon J. D. , Tracey Paul
Published: April 2021

Purpose is a concept often used in managerial communities to signal and define a firm’s benevolent and pluralistic approach to its stakeholders beyond its focus on shareholders. While some evidence has linked purpose to positive organizational outcomes such as growth, employee satisfaction, innovation, and superior stock market performance, the definition and application of purpose in management research has been varied and frequently ambiguous. We review literature streams that invoke purpose in the for-profit firm and propose a unifying definition. Next, we develop a framework to study purpose that decouples its framing and formalization within firms from its realization, thus helping to avoid conflation of the presence of purpose with positive organizational outcomes. The framework also highlights internal and external drivers that shape the framing of purpose as well as the influence of the institutional context on its adoption and effectiveness. Finally, we provide a rich agenda for future research on purpose.

Authors: Hott Brittany , Randolph Kathleen M. , Josephson Janet , Heiniger Sarah
Published: April 2021

The purpose of this study was to explore the efficacy of an electronic check-in, check-out (eCICO) intervention. The district’s case manager (i.e., guidance counselor) implemented the eCICO intervention remotely via FaceTime on an iPad in collaboration with the bus driver who facilitated student wireless internet access to a mobile hot spot. Results of the single-case multiple baseline across behaviors study suggest a functional relation between eCICO and the target bus behaviors of two rural students with emotional and behavioral disabilities. Further, low rates of target behaviors were maintained after eCICO was withdrawn. Implications for implementing eCICO interventions, limitations, and future research directions are discussed. Results of the study are reported using visual analysis, Tau-U, and percentage of non-overlapping data points.
International Migration and the (Un)happiness Push: Evidence from Polish Longitudinal Data
Authors: Brzozowski Jan , Coniglio Nicola
Published: April 2021

This article analyzes the impact of (un)happiness on the international migration decision. It uses a rich longitudinal household-level database, the Polish Social Diagnosis, to identify migration intentions, as well as subsequent actual migration, allowing us to overcome the issue of reverse causality present in previous studies of the nexus between happiness and migration. In addition, we assess the role of individual and household levels of happiness on migration behaviors and find that unhappy individuals from unhappy households are significantly more likely to declare their intentions to migrate abroad. In terms of actual migration, however, the unhappiness push significantly affects the odds of international migration only for selected subgroups, such as women and employed individuals. For other individuals, the unhappiness-induced migration plans remain mostly unrealized. Our article shows that push and pull factors, including happiness, might exert heterogenous effects on migration intentions and actual realizations. As a consequence, migration scholars should be careful when drawing conclusions on the determinants of actual migration behaviors by looking at determinants of migration intentions.
Does Emancipation Matter? Fertility of Chinese International Migrants to the United States and Nonmigrants during China’s One-child Policy Period
Authors: Nie Wanli , Baizan Pau
Published: April 2021

This article investigates the impact of international migration to the United States on the level and timing of Chinese migrants’ fertility. We compare Chinese women who did not leave the country (non-migrants) and were subject to restrictive family policies from 1974 to 2015 to those who moved to the United States (migrants) and were, thus, “emancipated” from these policies. We theoretically develop and empirically test the emancipation hypothesis that migrants should have a higher fertility than non-migrants, as well as an earlier timing of childbearing. This emancipation effect is hypothesized to decline across birth cohorts. We use data from the 2000 US census, the 2005 American Community Survey, the 2000 Chinese census, and the 2005 Chinese 1 percent Population Survey and discrete-time event history models to analyze first, second, and third births, and migration as joint processes, to account for selection effects. The results show that Chinese migrants to the United States had substantially higher childbearing probabilities after migration, compared with non-migrants in China, especially for second and third births. Moreover, our analyses indicate that the migration process is selective of migrants with lower fertility. Overall, the results show how international migration from China to the United States can lead to an increase in migrant women’s fertility, accounting for disruption, adaptation, and selection effects. The rapidly increased fertility after migration from China to the United States might have implications on other migration contexts where fertility in the origin country is dropping rapidly while that in the destination country is relatively stable.
Aorto-left common carotid artery bypass with off-pump coronary artery bypass
Authors: Nagata Tomoki , Yamada Takashi , Johno Hiroyuki
Published: April 2021

Background

Although carotid artery disease can occur in patients who have coronary artery disease (CAD), ostial stenosis of a left common carotid artery (CCA) along with CAD is a rarely reported condition.

Case report

We describe a rare case of severe stenosis of the left CCA ostium and CAD, which were successfully treated with an off-pump coronary artery bypass and aorto-left CCA bypass. This strategy minimizes the risk of perioperative strokes. Furthermore, an aorto-supra aortic trunk bypass provides a more physiological blood flow pattern than cerebral approaches. This approach would be a safe and effective treatment option.
Pneumomediastinum in COVID-19 disease: Outcomes and relation to the Macklin effect
Authors: Brito João , Gregório Paulo , Mariani Alessandro , D’ambrosio Paula , Filho Mauro , Ferreira Lorena , Sawamura Marcio , Pêgo-Fernandes Paulo Manuel
Published: April 2021

Aim

Pneumomediastinum (PM) is associated with several etiologies and mechanisms. Although it has been described more than 100 years ago, the literature is limited to small retrospective studies. This study aimed to follow patients with coronavirus disease (COVID-19) that developed PM during hospitalization and describe their clinical and radiological evolution.

Methods

A prospective cohort was developed with patients with PM, excluding those with aerodigestive trauma, inside a hospital COVID-19 dedicated hospital. Clinical variables including onset of symptoms, hemodynamic instability, associated complications, the need of interventions, and disease course were all recorded. Also, radiological findings such as the presence of the Macklin effect, extension of lung involvement by COVID-19, and characteristics of the PM were analyzed.

Results

Twenty-one patients with non-traumatic PM were followed, resulting in an overall incidence of 0.5% during the study period. Seven (33%) patients had associated pneumothorax and malignant/tension PM was observed in three (14%) cases. The Macklin effect could be found in 11 patients (52%) and the majority of them had more than 50% of lung involvement due to COVID-19. The mortality rate was 49%; however, no deaths were directly related to the PM.

Conclusions

PM incidence is probably increased in the severe acute respiratory syndrome caused by COVID-19, especially in those with greater involvement of the lungs, and the Macklin effect may be an important underlying mechanism of this complication. Usually, PM has a benign course, but complications like tension/malignant PM may occur requiring prompt detection and intervention.
Disparities in access to palliative care facilities for patients with and without cancer: A retrospective review
Authors: Lau Christine , Meaney Christopher , Morgan Matthew , Cook Rose , Zimmermann Camilla , Wentlandt Kirsten
Published: April 2021

Background:

To date, little is known about the characteristics of patients who are admitted to a palliative care bed for end-of-life care. Previous data suggest that there are disparities in access to palliative care services based on age, sex, diagnosis, and socioeconomic status, but it is unclear whether these differences impact access to a palliative care bed.

Aim:

To better identify patient factors associated with the likelihood/rate of admission to a palliative care bed.

Design:

A retrospective chart review of all initiated palliative care bed applications through an electronic referral program was conducted over a 24-month period.

Setting/participants:

Patients who apply and are admitted to a palliative care bed in a Canadian metropolitan city.

Results:

A total of 2743 patients made a total of 5202 bed applications to 9 hospice/palliative care units in 2015–2016. Referred and admitted cancer patients were younger, male, and more functional than compared to non-cancer patients (all p < 0.001). Referred and admitted patients without cancer were more advanced in their illness trajectory, with an anticipated prognosis <1 month and Palliative Performance Status of 10%–20% (all p < 0.001). On multivariate analysis, a diagnosis of cancer and a prognosis of <3 months were associated with increased likelihood and/or rate of admission to a bed, whereas the presence of care needs, a longer prognosis and a PPS of 30%–40% were associated with decreased rates and/or likelihood of admission.

Conclusion:

Patients without cancer have reduced access to palliative care facilities at end-of-life compared to patients with cancer; at the time of their application and admission, they are “sicker” with very low performance status and poorer prognoses. Further studies investigating disease-specific clinical variables and support requirements may provide more insights into these observed disparities.

Much ado about eating: Intermittent fasting and post-stroke neuroprotection
Authors: Vemuganti Raghu , Arumugam Thiruma V
Published: April 2021

A proper diet is important for health and longevity. Controlling the amount of food consumed is immensely beneficial as it promotes multiple cellular and molecular protective mechanisms and simultaneously prevents toxic mechanisms. Intermittent fasting (IF) is a flexible and easy-to-adopt dietary modification that helps to mitigate metabolic disorders like diabetes and hypertension, and thus the devastating age-related diseases like heart attack, stroke and dementia. The benefits of IF seem to be mediated by altered epigenetic and transcriptional programming leading to reduced oxidative stress, inflammation, mitochondrial damage and cell death.
Diagnostic performance of computed tomography and diffusion-weighted imaging as first-line imaging modality according to the International Myeloma Working Group (IMWG) imaging algorithm for monoclonal plasma cell disorders
Authors: Yoon Min A , Chee Choong Guen , Chung Hye Won , Lee Dong Hyun , Kim Kyung Won
Published: April 2021

Background

The latest International Myeloma Working Group (IMWG) guideline recommends low-dose whole-body (WB) computed tomography (CT) as the first-line imaging technique for the initial diagnosis of plasma cell disorders.

Purpose

To evaluate diagnostic performances of CT and diffusion-weighted imaging (DWI) as the first-line imaging modalities and assess misclassification rates obtained following the guideline.

Material and Methods

Two independent radiologists analyzed CT (acquired as PET/CT) and DWI (3-T; b-values = 50 and 900 s/mm2) of patients newly diagnosed with plasma cell disorder, categorizing the number of bone lesions. Diagnostic performance of CT and DWI was compared using the McNemar test, and misclassification rates were calculated with a consensus WB-MRI reading as the reference standard. Differences in lesion number categories were assessed using marginal homogeneity and kappa statistics.

Results

Of 56 patients (36 men; mean age = 63.5 years), 39 had myeloma lesions. DWI showed slightly higher sensitivity for detecting myeloma lesions (97.4%) than CT (84.6%–92.3%; P > 0.05). CT showed significantly higher specificity (88.2%) than DWI (52.9%–58.8%; P<0.05). CT had a higher additional study requirement rate than DWI (7.7%–15.4% vs. 2.6%), but a lower unnecessary treatment rate (11.8% vs. 41.2%–47.1%). Both readers showed significant differences in categorization of the number of lesions on CT compared with the reference standard ( P < 0.001), and one reader showed a significant difference on DWI ( P = 0.006 and 0.098).

Conclusion

CT interpreted according to the IMWG guideline is a diagnostically effective first-line modality with relatively high sensitivity and specificity. DWI alone may not be an acceptable first-line imaging modality because of low specificity.
Sarcoidosis during treatment of pulmonary tuberculosis: a rare case report and review of the literature
Authors: Cho Hye Soo , Kim Sung Jin , Yoo Jin Young
Published: April 2021

The coexistence of pulmonary tuberculosis and pulmonary sarcoidosis is rare. Further, the morphological features of pulmonary tuberculosis with comorbid pulmonary sarcoidosis are similar to those of tuberculosis alone. There are obvious clinical, histological, and radiological similarities between sarcoidosis and tuberculosis, which makes differential diagnosis very challenging, particularly in countries with a high burden of tuberculosis. Here, a rare case of computed tomography (CT) findings of sarcoidosis that developed during tuberculosis treatment is reported. The 46-year-old male patient had no significant symptoms and was undergoing treatment for Mycobacterium tuberculosis infection. Chest CT revealed enlargement of multiple lymph nodes, without cystic or necrotic changes, in the mediastinum and both hili, and post-infectious changes consistent with the sequelae of tuberculosis infection in the left upper lobe. Chest radiographic evidence was accompanied by compatible clinical features and noncaseating granulomas on biopsy. As the patient was clinically stable, corticosteroid treatment was not initiated. To date, the patient remains without specific symptoms and outpatient follow-ups continue. Although rare, sarcoidosis may occur during treatment of pulmonary tuberculosis, and requires attention for diagnosis and treatment. The present case draws a radiological picture of how tuberculosis evolved to sarcoidosis.

Authors: Ma Yibo , Liu Shuiqing , Yang Min , Zou Yun , Xue Dong , Wang Yufeng , Xie Xiao , Chen Hui , Liu Yanping
Published: April 2021

Objective

To investigate the factors involved in early and mid-term complications after catheter insertion for peritoneal dialysis and to establish prediction models.

Methods

A total of 158 patients with peritoneal dialysis in the Department of Nephrology of our hospital were retrospectively analyzed. General information, laboratory indices, early complications (within 1 month after the operation), mid-term complications (1–6 months after the operation), and other relevant data were recorded. Multivariate logistic regression analysis was performed to establish a prediction model of complications and generate a nomogram. Receiver operating characteristic (ROC) curve analysis was used to evaluate the efficacy of the model.

Results

Among the patients, 48 (30.8%) had early complications, which were mainly catheter-related complications, and 29 (18.4%) had mid-term complications, which were mainly abdominal infection and catheter migration. We constructed a prediction model for early complications (area under the curve = 0.697, 95% confidence interval: 0.609–0.785) and mid-term complications (area under the curve = 0.730, 95% confidence interval: 0.622–0.839). The sensitivity was 0.750 and 0.607, and the specificity was 0.589 and 0.765, respectively.

Conclusions

Our prediction model has clinical significance for risk assessment of early and mid-term complications and prevention of complications after catheterization for peritoneal dialysis.

Authors: Wang Yongfeng , Lai Rongtao , Zong Peilan , Xu Qingling , Shang Jia , Zhang Xia , Zhong Wei , Tang Jieting , Han Xi’an , Chen Chengwei , Mao Yimin
Published: April 2021

Objective

To evaluate the efficacy and safety of bicyclol in patients with drug-induced liver injury (DILI) using a nationwide database.

Methods

We retrospectively analyzed the clinical data of DILI patients in the DILI-R database. Propensity score matching was performed to balance the bicyclol and control groups, and alanine aminotransferase (ALT) recovery was compared between the two groups. Factors associated with ALT recovery and safety were identified.

Results

The analysis included the data of 25,927 patients. Eighty-seven cases were included in the bicyclol group, with 932 cases in the control group. One-to-one propensity score matching created 86 matched pairs. The ALT normalization rate in the bicyclol group was significantly higher than that in the control group (50.00% vs. 24.42%), and statistical significance was found in the superiority test. After adjustment of baseline ALT levels, baseline total bilirubin levels, sex, age, acute or chronic liver diseases, and suspected drugs in the multivariate logic regression analysis, the major influencing factors for ALT recovery included the time interval between ALT tests (days) and the group factor (bicyclol treatment). There were no differences in the proportion of renal function impairment or blood abnormalities between the two groups.

Conclusions

Bicyclol is a potential candidate for DILI.
Gender Differences in Theory of Mind, Empathic Understanding, and Moral Reasoning in an Offending and a Matched Non-Offending Population
Authors: Spenser Karin A. , Bull Ray , Betts Lucy , Winder Belinda
Published: April 2021

Previous research suggests that a lack of pro-social skills is characteristic of an offending personality. Two hundred male and female offenders and matched controls completed measures to assess: Theory of Mind, empathic understanding, and moral reasoning. Significant differences between the offenders and the control group, as well as between the male and female participants, were detected in theory of mind, empathic understanding and moral reasoning with offenders scoring lower than the control group, and with males scoring lower than females on most tests. The ability to assess Theory of Mind, empathic understanding, and moral reasoning, and subsequently to identify reduced ability, is not only useful for researchers but will also allow practitioners to tailor existing (or develop new) interventions specific to the needs of individuals. This could be particularly useful in terms of recidivism when applied to those involved in anti-social or offending behavior.

Published: April 2021

Self-harm is one of the most common reasons for admission to an intensive care unit (ICU). While most patients with self-harm survive the ICU admission, little is known about their outcomes after hospital discharge. We conducted a retrospective cohort study of patients in the Barwon region in Victoria admitted to the ICU with self-harm (between 1998 and 2018) who survived to hospital discharge. The primary objective was to determine mortality after hospital discharge, and secondarily estimate relative survival, years of potential life lost, cause of death and factors associated with death. Over the 20-year study period, there were 710 patients in the cohort. The median patient age was 37 years (interquartile range (IQR) 26–48 years). A total of 406 (57%) were female, and 527 (74%) had a prior psychiatric diagnosis. The incidence of ICU admission increased over time (incidence rate ratio 1.05; 95% confidence interval (CI) 1.03–1.06 per annum). There were 105 (15%) patients who died after hospital discharge. Relative survival decreased each year after discharge, with the greatest decrement during the first 12 months. At ten years, relative survival was 0.85 (95% CI 0.81–0.88). The median years of potential life lost was 35 (IQR 22–45). Cause of death was self-harm in 27%, possible self-harm in 32% and medical disease in 41%. The only factors associated with mortality were male sex, older age and re-admission to ICU with self-harm. Further population studies are required to confirm these findings, and to understand what interventions may improve long-term survival in this relatively young group of critically ill patients.
LMA® Gastro™: A paediatric experience
Authors: Taylor Charlotte L , Wilson Steven R , Burgoyne Laura L , Endlich Yasmin
Published: April 2021

The laryngeal mask airway, the LMA® Gastro™ (Teleflex Medical, Athlone, Ireland), is a novel airway device which permits upper gastrointestinal (GI) endoscopy to be performed via a dedicated large calibre oesophageal lumen. It has been validated in adult studies, but to our knowledge, there have been no data published regarding its use in a paediatric population. Following a brief education programme, the LMA Gastro was introduced on a trial basis at our institution and made freely available. Over a four-month period, our pre-existing endoscopy audit framework captured data on a total of 55 patients who had the LMA Gastro device chosen as the primary airway for elective upper GI endoscopy. These data were collected prospectively by the treating anaesthetist and included a range of airway and endoscopy outcomes. Of the 55 patients, the LMA Gastro provided an adequate airway in 52 (94.5%). Forty-six (88.5%) were sited on first attempt, and 50 (96.2%) insertions were rated ‘easy’ by the anaesthetist. Aside from three insertion failures, there were no airway events. The endoscopy success rate was 100% in the 52 patients who had an LMA Gastro airway successfully inserted. First-pass oesophageal access was achieved in 51 (98%) cases, and 100% of insertions were rated ‘easy’ by the gastroenterologist. Despite our relative inexperience with it, the device had a high success rate for airway maintenance and oesophageal access in our paediatric patient population. In our institution, the LMA Gastro provided a useful airway option in older children undergoing elective upper GI endoscopy.
Simulation of Potential Use Cases for Shared Mobility Services in the City of Ann Arbor
Authors: Twumasi-Boakye Richard , Cai Xiaolin , Fishelson James , Broaddus Andrea
Published: April 2021

In this paper, we model and simulate special use cases of on-demand shared mobility services for the City of Ann Arbor, MI. We define shared mobility as any motor-vehicle-served transportation option between private vehicles and public transit, such as taxis, demand-responsive transit, and dynamic shuttles. Here, we present and evaluate a suite of four diﬀerent service types that could potentially complement existing transportation services in Ann Arbor. A novel aspect of this study is that it tests scenarios that were developed in consultation with city planners looking for insights into real-world problems. This study used fleet simulation software to test four service configuration scenarios for a hypothetical on-demand shared mobility service: citywide shuttle, a corridor-based downtown shuttle, a park and ride shuttle, and a transit-complementary service. Three levels of demand were tested for each scenario: 3%, 9%, and 15% of all private vehicle trips in the city. Findings indicated that citywide on-demand shared mobility services struggled to achieve higher vehicle occupancies than private vehicles at approximately 1.4. Service configurations with aggregated trip density resulted in slightly improved occupancies, as found in downtown- and park and ride shuttle scenarios. More impactful was aggregating demand by moving from “many-to-many” routing as with citywide floating services to “many-to-one” routing as with downtown- or park and ride shuttle services, which increased vehicle occupancy from 1.4 to almost 2. Lastly, we also discuss the potential beneﬁts of reduced congestion and parking needs.
Evaluation of the Circles Measurement and the ABC Classification of Acromioclavicular Joint Injuries
Authors: Murphy Richard J. , Moor Beat K. , Lesniewski Piotr J. , Hayoz Annabel , Alcantara Wolfan , Zumstein Matthias A.
Published: April 2021

Background:

Acromioclavicular joint (ACJ) injuries are common. Despite this, it remains unclear how best to assess, classify, and manage these cases. A simple, reliable, valid, and accurate radiographic parameter to measure ACJ displacement would allow improved consistency of diagnosis and subsequent treatment pathways.

Purpose:

To evaluate “the circles measurement” and associated “ABC classification” as a tool for assessing ACJ displacement and injury classification.

Study Design:

Descriptive laboratory study.

Methods:

The circles measurement is taken from a lateral Alexander radiograph of the shoulder. The measurement is the center-to-center distance between 2 circles drawn to define the lateral extent of the clavicle and the anteromedial extent of the acromion; it is independent of the displacement plane, judging total ACJ displacement in any direction rather than trying to quantify vertical and/or horizontal displacement. When utilized clinically, the circles measurement is a single measurement calculated as the difference between values recorded for the injured and uninjured sides. Validation of the circles measurement was performed using lateral Alexander radiographs (including ±20° projection error in all planes) and computed tomography of standardized ACJ injury simulations. We assessed inter- and intrarater reliability, convergent validity, and discriminant validity of the circles measurement and subsequently generated a classification of ACJ injury based on displacement.

Results:

Reliability and validity of the circles measurement was excellent throughout. Interrater reliability (ICC [intraclass correlation coefficient] [2,1], 95% CI; n = 78; 4 observers) was 0.976 (0.964-0.985). Intrarater reliability (ICC [2,1]; 95% CI; n = 78; 2 measures) was 0.998 (0.996-0.998). Convergent validity (Pearson correlation coefficient, r) was 0.970 for ideal radiographs and 0.889 with ±20° projection error in all planes. Discriminant validity, with 1-way analysis of variance, showed a P value of <.0001 and effect size ( η2) of 0.960, with the ability to distinguish between the previously defined stable (Rockwood IIIA) and unstable (Rockwood IIIB) injuries. The results permitted objective, statistically sound parameters for the proposed ABC classification system.

Conclusion:

The circles measurement is a simple, reliable, valid, accurate, and resilient parameter for assessing ACJ displacement and can be used in conjunction with the proposed ABC classification to define ACJ injuries more accurately and objectively than previously described.

Clinical Relevance:

This novel parameter has the potential to standardize the initial assessment and possibly the subsequent clinical management of ACJ injuries, in addition to providing a standardized measure for future research.
Love or Bread? Public Service Motivation and Fringe Benefits in the Retention of Police Forces in Beijing City
Authors: Hu Wei , Huang Irving Yi-Feng , Yang Weiwen
Published: April 2021

Drawing upon the job demands-resources model (JD-R) and self-determination theory, this study investigates whether a set of fringe benefit initiatives taken by the police organization was able to relieve perceived work–family conflict and further reduce policemen’s intention to leave the job. A survey of 421 respondents from Beijing City Police Bureau revealed a positive relationship between work pressure, work–family conflict (WFC), and turnover intention (TI), showing that the satisfaction of fringe benefits (SFB) can moderate the linkage between WFC and TI. However, the moderating role of SFB would be crowded out when the participants possess higher level of public service motivation (PSM). This suggests that organizational support via fringe-benefit policy helps to decrease turnover intention only among employees who possess lower PSM. These findings demonstrate a special interaction of external benefits and PSM in the context of retaining police forces.
Traditional and Modern Convenience Samples: An Investigation of College Student, Mechanical Turk, and Mechanical Turk College Student Samples
Authors: Weigold Arne , Weigold Ingrid K.
Published: April 2021

Two of the most popular populations for convenience sampling used in the psychological sciences are college students and Mechanical Turk (MTurk) workers. College students represent a traditional type of convenience sample, whereas MTurk workers provide a more modern source of data. However, little research has examined how these populations differ from each other in salient characteristics. Additionally, no research to date has investigated how MTurk college students (a traditional sample collected using modern methods) compare to either population. The current study examined 1,248 participants comprising three samples: MTurk noncollege workers ( n = 533), MTurk college students ( n = 385), and traditional college students ( n = 330). We compared the samples on demographic characteristics, study completion time, attention, and individual difference variables (i.e., personality, social desirability, need for cognition, personal values, and social attitudes). We examined the individual difference variables in terms of mean responses, internal consistency estimates, and subscale intercorrelations. Results indicated the samples were distinct from each other in terms of all variables assessed; in addition, adding demographic characteristics as covariates to the analyses of individual difference variables did not effectively account for sample differences. We conclude that research using convenience samples should take these differences into account.

Published: April 2021

An experimental study is conducted to show the influence of the tubes material type of the heat exchanger on the refrigeration system performance. The system is operated by using R134a as a working fluid, 2 mm internal diameter, and different lengths of capillary tubes which were 120, 135, and 150 cm. The experimental results showed that when increasing the refrigerant mass flowrates led to reducing each of the performance coefficient COP, number of transfer unit NTU and evaporator effectiveness ε. However, the highest improvement had appeared for each parameter COP, NTU, and ε which were 21%, 113.38%, and 59.42% respectively at a capillary tube length of 120 cm and [Formula: see text] = 3.19 g/s compared to the length of capillary tube 150 cm. Besides, it was found an increase in [Formula: see text] with the incrementing in the capillary tube length from 120 cm to 150 cm. The biggest percentage of compression power was 23% at the capillary tube length of 150 cm compared to others at [Formula: see text] = 3.71 g/s. Finally, the experimental results of COP and [Formula: see text] were validated by comparing them with other publications.
Research on driving proneness in car-following behaviours based on multi-source real driving data
Authors: Li Shiwu , Zhao Shishu , Guo Mengzhu
Published: April 2021

There is little research on the degrees of drivers’ short-term behaviours regarding driving safety. To solve this problem, this paper investigated the concept of driving proneness and evaluated the propensities of different drivers to engage in different operations for the following scenarios of urban traffic. From the real driving data of sixteen drivers on a city road, car-following data fragments were extracted and six key parameters were obtained: throttle percentage, change rate of throttle percentage, brake pressure, change rate of brake pressure, absolute value of steering angle and absolute value of steering angle speed. Symbolic Aggregate Approximation was used to reduce the dimensionality of the parameters. The input of the Hidden Markov Model-Viterbi was obtained by the use of statistical methods. The output of the model is the probability of the three proneness states of introversion, neutrality and extroversion, from which the proneness value of each driver was calculated. The weighted proneness value of each driver was obtained by the use of the entropy weight method to assign weights to each parameter. The operating characteristics of the drivers were also analysed and described. The method presented in this paper can provide accurate and real-time warning in network-driven environments.

Published: April 2021

A comprehensive analysis of the intake valve opening duration (IVOD) effects on the performance of an Atkinson cycle engine is conducted in this work using numerical simulation and experimental validation. Through one-dimensional simulation, the relationship between the range of IVOD and the compression ratios is firstly investigated under the constraint of compression pressure. Two representative IVOD, 295 and 314°CA, are then respectively applied to the performance simulation and experiment of a practical Atkinson cycle engine. The simulation shows the combination of a late intake valve opening timing (IVO) angle and a late exhaust valve opening timing (EVO) angle is profitable for improving the fuel economy under part load operating conditions (i.e. 2000 rpm@2 bar and 3000 rpm@3 bar). The experimental results present the Atkinson cycle engine under both IVOD scenarios considerably improves the brake specific fuel consumption (BSFC) and reduces the pumping mean effective pressure (PMEP) compared to those of the original Otto cycle engine. Meanwhile, the comparison between two IVOD scenarios show that the shorter IVOD leads to an improvement of indicated thermal efficiency, especially at lower load. Considering fuel economy, a shorter IVOD is more favorable at part load for the Atkinson cycle engine. Two main contributions of this work are to numerically quantify the IVOD range for the Atkinson cycle engine under part load, and to experimentally validate the effectiveness of simulation. The findings of this work are expected to support the design of Atkinson cycle engines and provide a guideline of IVOD optimization under part load.
Ecological footprint, human capital, and urbanization
Authors: Chen Yang , Lee Chien-Chiang , Chen Ming
Published: April 2021

The rapid development of the world economy has been accompanied by a significant increase in ecological footprint. Represented by population agglomeration, urbanization has exacerbated environmental pressure, but the improvements in the levels of human capital may offset this negative impact. This research thus uses cross-country data from 110 economies over the period 1990–2016 to explore the correlations among human capital, urbanization, and ecological footprint. The findings show that first, from a global perspective, human capital initially increases and then reduces ecological footprint. The analysis based on sub-samples shows that human capital of the high-income group decreases ecological footprint, whereas human capital of the low-income group and that of countries with large populations raise ecological footprint. Second, urbanization plays a linear moderating role in human capital’s impact on the ecological footprint. The higher the level of urbanization is, the higher is the turning point of human capital that is needed to improve environmental quality. Third, when the population size is larger or ecological footprint is greater, the turning point of human capital is higher under the same urbanization level. Therefore, countries should continue to enhance human capital to promote the upgrading of industrial structure, green technology innovation, and changes in energy-saving lifestyle. Moreover, it is beneficial for countries to pay close attention to the negative impact of population size or accelerated urbanization on environmental quality.
Ethical realism before social constructionism
Authors: Bøe Tore Dag
Published: April 2021

In this article, I explore the idea that there is a fundamental ethical aspect that precedes social constructionism. I suggest that within social constructionism we can identify a development from seeing knowledge as socially constructed ( epistemological social constructionism) to seeing not only knowledge, but also corporeal ways of being as socially constructed ( ontological social constructionism). As a next step, I propose incorporating what I refer to as ethical realism in social constructionist perspectives. In the encounter with the other human being, I argue that there is a real ethical impulse that precedes social constructionism and puts it in motion. This impulse is real in the sense that it is neither constructed within, nor is it dependent upon, any particular social–cultural–historical context. In this paper I consider the ethical aspects of human encounters that allow for a constructionist epistemology and ontology to emerge in the first place. I make use of ideas from Emmanuel Levinas and Jacques Rancière and consider how these thinkers are used in the work of Gert Biesta. The ideas are discussed in relation to findings from a previous study by the author and his colleagues exploring the experiences of adolescents taking part in mental health services.
Nailfold capillaroscopy findings in cutaneous lupus erythematosus patients with or without digital lesions and comparison with dermatomyositis patients: A prospective study

Published: April 2021

Background

Differential diagnosis between cutaneous lupus erythematosus (CLE) and dermatomyositis (DM) may be challenging if digital lesions occur.

Objectives

To compare nailfold capillaroscopy (NFC) findings in CLE patients with or without digital involvement, and to compare capillaroscopic findings between CLE patients with digital lesions and DM patients.

Methods

Prospective monocentric study including CLE and DM patients. NFC was performed and standardized items were recorded.

Results

Fifty-one CLE patients and 10 DM patients with digital lesions were included. A scleroderma pattern was found in 6 patients (12%): in 5 out of 17 patients with digital lesions, compared with only 1 out of 34 patients without digital lesions (p = 0.01). In multivariate analysis, CLE digital lesions and digital ulcerations were statistically associated with scleroderma pattern. CLE digital lesions were significantly associated with architectural disorganization (p = 0.0003) and capillary rarefaction (p = 0.0038). A scleroderma pattern was significantly more frequent in DM patients (80%) than in CLE patients with digital lesions (30%, p = 0.018). Capillaroscopic findings were not significantly different between CLE patients with digital lesions and DM patients.

Conclusion

Although scleroderma pattern is more frequent in DM patients than in CLE patients with digital lesions, NFC cannot formally distinguish CLE from DM.
For or against genetically modified foods: Different discursive strategies in Chinese social media
Authors: Lin Jinrong
Published: April 2021

This study investigates the discourse of a long-lasting social debate over the safety of genetically modified food in China. Based on data from the social media platform WeChat, it adopts the perspective of critical discourse analysis to analyze what strategies are used in discourses of Chinese genetically modified foods to construct identities of the two opposing sides in genetically modified debates. The two sides use different rhetorical devices, argumentative strategies, and intertextual historical elements. Specifically, opponents of genetically modified food are inclined to use metaphors, moralization, intertextual proverbs, and revolutionary inflection to legitimize their position, while supporters often use irony, authorization, and historical allusions to legitimate as well as enhance their hegemony. I suggest that exploring how each side strategically constructs a discourse may facilitate better understanding and mitigate conflict between the two polarized viewpoints represented in social media.
Diffusion of Banking Products in Financial Inclusion Linked Savings Accounts: A Case Study Based on Pradhan Mantri Jan Dhan Yojana in India
Authors: Singh Vinay Kumar , Prasad Rohit
Published: April 2021

The slow rate of adoption of savings and transaction accounts opened under financial inclusion programmes is a challenge for policymakers across the globe. We use the experience of a large-scale financial inclusion programme in India—Pradhan Mantri Jan Dhan Yojana (PMJDY)—to model the adoption of simple banking products, namely deposit, withdrawal, fund transfer and ATM usage. Based on account-level transaction data, we create a dataset to capture the adoption of each product over time. We use this data to estimate three growth models: Bass, Gompertz and logistic. The Bass model which is based on diffusion of innovations theory is found to be the best fit across products. The role of social influence in the diffusion of the four products studied is found to be much lower when compared to other products in subsistence marketplaces. Social network effect is comparatively stronger in the adoption of fund transfer and ATM. We discuss the mechanisms underlying this phenomenon and contend that information transfer by word of mouth and network effects are the most probable reasons for the observed adoption behaviour.
Urban-Rural Compliance Variability to COVID-19 Restrictions of Indigenous Fijian (iTaukei) Funerals in Fiji
Authors: Vave Ron
Published: April 2021

Research on coronavirus disease 2019 (COVID-19) has focused primarily on impacts in Western societies despite emerging evidence of increased vulnerability among indigenous peoples such as Pacific Islanders. Using Facebook public posts, this research assessed compliance to COVID-19 restrictions such as social gatherings (SG) and social distancing (SD) in non-COVID-19, indigenous Fijian ( iTaukei) funerals in Fiji. Results showed 95% of the 20 funerals exceeding SG limits with greater, and highly variable crowd sizes in rural than urban communities. Additionally, 75% of the 20 funerals did not adhere to the 2-m SD requirement of which 80% were in rural areas. Higher SG and SD compliance in urban funerals could be partially explained by the presence of a recognized authority who enforced crowd size limits, and the heterogeneous urban community who were more likely to flag breaches than their collectivistic, homogeneous, close-knit, rural counterparts. Ultimately, health authorities need to utilize a social lens that incorporates etic and emic differences in culture to ensure maximum compliance.
