Social innovation within transnational flows of knowledge: The example of student mobility from Bulgaria

Taking the example of Bulgarians who studied abroad, this paper explores the motives and practices of graduates regarding socially innovative knowledge transfer in order to deliver social benefits for the local community. The paper shows how both stayers and returnees act within a transnational social space, which develops and deepens during and after student mobility. Engaging in socially innovative knowledge transfer is motivated by altruistic stances, by a feeling of loyalty towards the home country and by the desire to lead a meaningful life. The effectiveness of knowledge transfer is related to framing conditions such as local knowledge and the existence of social networks, notably transnational social networks. The results show that the mobility of highly qualified young adults from and to Bulgaria aligns with major European mobility regimes, with an increase of circulatory mobility processes and thus an increase of circulating knowledge and social innovation.
A randomized controlled trial of an app-delivered mindfulness program among university employees: effects on stress and work-related outcomes

The purpose of this paper is to evaluate the impact on stress and work-related outcomes of an app-delivered mindfulness-based program (MBP; Headspace®) offered to employees in a UK higher education (HE) institution. ,Using a randomized waitlist control trial design, participants were randomly allocated to be offered a mindfulness-based program (MBP) immediately for 2 months or after a waiting list period of 2 months (WLC). Data were analyzed using Intention to Treat (ITT; MBP n = 62; WLC n = 63); with supplementary analysis restricting to those who completed all measures; (MBP n = 45; WLC n = 56) and then further restricting the MBP group to those who completed at least foundation level 1 of the app; (MBP n = 31; WLC n = 56). ,The ITT analysis showed significant increases in several aspects of mindfulness and a significant reduction in perceived stress but no significant effects for work-related outcomes. Analysis restricted to MBP participants who completed the app foundation course showed a similar pattern but in addition showed significant increases in work-life balance and the emotional aspect of job engagement. ,The offer of the Headspace® app in the HE sector may result in reduced perceived stress. If improvements in work-related outcomes are also to be seen, then users need to be encouraged to complete a minimum level of practice. ,Effect size estimates for stress and work-related outcomes of an app-delivered MBP contribute to the evolving picture of MBPs in the workplace.
Coaches’ influence on team dynamics in sport: A scoping review

ABSTRACT Although extensive sport research has been dedicated to understanding coach effectiveness, this work has largely explored how coaches’ behaviours influence individual athletes rather than considering the total team. Accordingly, we sought to examine the breadth of existing research involving the influence of coaches on team dynamics. Adhering to PRISMA for Scoping Review guidelines, 9,454 peer–reviewed studies were identified using four electronic databases, with 82 ultimately meeting inclusion criteria. Studies were grouped based on interpersonal, intrapersonal, and professional coach behaviours. Within these groups, team dynamics frameworks were used to explore the team–level variables. The results demonstrated that the majority of research has focused on coaches’ interpersonal behaviours on teams’ emergent states, while largely overlooking the influence of coaches’ intrapersonal or professional behaviours on teams’ structures or processes. We advocate for the diversification of methodologies employed and targeted investigations guided by established frameworks to better understand coaches’ influence on team dynamics.
Platform Encroachment and Own-Content Bias

This paper presents a model of platform encroachment, in which a platform not only acts as an intermediary between consumers and third-party sellers, but also sells its first-party products. When encroaching, the platform chooses between fair and biased search engines. Under the fair search, all products are equally likely to appear in search results, whereas the first-party product is more likely to appear under biased search. Biased encroachment makes the platform impose a lower commission on sellers, which leads to a lower equilibrium price which consequently attracts more consumers. Increased consumer participation can raise seller participation through indirect network externalities.
Weakly nonlinear Holmboe waves

Holmboe waves are long-lived traveling waves commonly found in environmental stratified shear flows. Here we study their finite-amplitude properties in the nonlinear but nonturbulent regime, with a weakly nonlinear temporal stability analysis. Using a versatile amplitude expansion method, we analyze supercritical bifurcation diagrams both in Reynolds number and Richardson number, transient phase portraits, and the vertical structures of all components modes up to third order. We believe these results provide a basis for a future fully nonlinear analysis of the Holmboe dynamical system.
Strength in numbers? Understanding the effect of team-level PSM on team effectiveness

Abstract To date, public service motivation (PSM) has been investigated only as an individual-level phenomenon. We argue that, in order better to understand team effectiveness in public organizations, it is essential that team characteristics are also taken into consideration. This study provides a key contribution to public management research by exploring the relationship between PSM and team effectiveness at the group level. Specifically, we introduce the concepts of team-level PSM, which describes the average level of PSM within a team, and PSM differentiation, which refers to the variance in PSM that exists across different members of a team. The data used for this study are based on a two-wave survey of 122 teams of public sector employees in Switzerland. Findings show that team-level PSM is indirectly related to team effectiveness through the process of team identification and that this relationship is strengthened when there is less variability in PSM within the team. The implications of our findings for theory and practice are discussed.
Growth Performance of Indian Major Carps at Pond System Using Shrimp Industry Waste in their Diet

A study was carried out to observe the growth performance of Indian major carp utilizing the shrimp industry waste in their supplementary diets in pond system during 1st January to 30th June, 2015. Two types of diet namely Diet-1 (Formulated feed with shrimp waste), Diet-2 (Formulated feed with plants source ingredients) were prepared while Diet-3 (Commercial feed) were purchased from the market and assigned to three treatments viz. T1, T2 and T3. Protein percentage of diets were 28.42%, 28.13% and 27.32%, respectively. The water quality parameters of the experimental ponds were monitored at 10 days interval. Diet-1 resulted better growth with Labeo rohita (153.68g), Gibelion catla (170.14g) and Cirrhinus cirrhosus (84.83g) compared to Diet-2 (138.99g, 152.94g, 68.39g respectively). The highest SGR (%/day) value was obtained with Labeo rohita (2.66%/day), Gibelion catla (2.59%/day) and Cirrhinus cirrhosus (2.62%/day) for Diet-3. The average protein efficiency ratio (PER) for Diet-1 (2.19) differed much to that of Diet-2 (2.03) where Diet-3 (2.38) showed highest PER value. The highest survival rate (%) with Labeorohita (93.93%), Gibelioncatla (92.86%) Cirrhinuscirrhosus (94.44%) were found for Diet-3. Therefore, it could be recommended that shrimp industry waste can be replaced with fish meal in the diets of Indian major carps along with other available feed ingredients.
On the Choice of Metric to Calibrate Time-Invariant Ensemble Kalman Filter Hyper-Parameters for Discharge Data Assimilation and Its Impact on Discharge Forecast Modelling

An important step when using some data assimilation methods, such as the ensemble Kalman filter and its variants, is to calibrate its parameters. Also called hyper-parameters, these include the model and observation errors, which have previously been shown to have a strong impact on the performance of the data assimilation method. Many metrics can be used to calibrate these hyper-parameters but may not all yield the same optimal set of values. The current study investigated the importance of the choice of metric used during the hyper-parameter calibration phase and its impact on discharge forecasts. The types of metrics used each focused on discharge accuracy, ensemble spread or observation-minus-background statistics. The calibration was performed for the ensemble square root Kalman filter over two catchments in Canada using two different hydrologic models per catchment. Results show that the optimal set of hyper-parameters depended heavily on the choice of metric used during the calibration phase, where data assimilation was applied. These sets of hyper-parameters in turn produced different hydrologic forecasts. This influence was reduced as the forecast lead time increased, because of not applying data assimilation in the forecast mode, and accordingly, convergence of model state ensembles produced in the calibration phase. However, the influence could remain considerable for a few days up to multiple weeks depending on the catchment and the model. As such, a preliminary analysis would be recommended for future studies to better understand the impact that metrics can have within and outside the bounds of hyper-parameter calibration.
Effects of Mixtures on Liquid and Solid Fragment Size Distributions

Abstract : Mixing naturally occurs when the tensile strain rates that drive fragmentation vary with time and/or space. Understanding such mixtures requires understanding the ingredients, i.e., simple fragmentation driven by steady uniform strain rates in a fixed dimension. Theoretical proofs are given showing that simple fragmentation as well as its inverse, simple coagulation leads to an infinite but discrete set of universal size distributions. This conclusion is a middle ground between previous studies which found one universal, two universals, or an infinite continuum of non-universals. This paper finds that complex multi-stage fragmentation events may often be treated, in aggregate, as virtual simple single-stage fragmentation events.
Strategy as learning in multi-academy trusts in England: strategic thinking in action

ABSTRACT Multi-academy trusts are groups of schools in England led by an Executive Head Teacher and a Board of Trustees. High profile failures of these organisations raise questions over the way they are strategically led. Leadership studies argue that the absence of strategic thinking is a major detractor from performance & sustainability. However, creating strategy for a single organisation is very different to creating it for a collaboration. This article adopts a schema-based approach to examine the ways in leadership boards approach strategy as learning. Drawing on 42 qualitative interviews it asks: What evidence is there that strategy is a learning activity; What organisational implications are there for this? What are the implications of this for Trustee and CEO development in this area? And what theoretical contribution does this study make to what is known about strategy learning in multi-level organisations? The paper concludes that there is evidence to suggest that respondents view strategy as learning, whilst also suggesting areas for professional development for school leaders. From a theoretical perspective, the paper adds to knowledge on the role of metacognition in a strategy as learning approach to strategic decision-making.
Determinants on COVID-19 Case Fatality Rates of Cities in China: A Logit-NB Hurdle Model Analysis

Background: The ongoing Coronavirus Disease 2019 (COVID-19), a global pandemic with high infectiousness and high mortality, has seriously threatened human health, life safety and caused enormous economic losses. This study investigates the influencing factors on the case fatality rate (CFR) of COVID-19 at the city level in China. Methods: A logistic-negative binomial (Logit-NB) hurdle model is employed to examine the determinants on the probability of death and the value of CFR with COVID-19, based on confirmed cases and deaths by 13 March 2020 and 25 January 2021 at the city level in China and related environmental, demographic, and socioeconomic data.Results: We found that the probability of death from COVID-19 will increase by 1% with 1 newly increased confirmed case and increase by 4% in response to a rise of 1 unit in the air quality index. CFR will feebly increase with the number of confirmed cases, with the estimator being 2.81E-05. As the number of doctors increases by 10,000, CFR will decrease by 0.18%. Each 1% increase in the humidity leads to a 0.02% decrease in CFR, and each 1-unit increase in the population density causes a 0.09% decline in CFR. The comparison between the two research periods confirms the robustness of the results.Conclusions: The number of confirmed cases and the air quality are closely associated with the death probability, while the number of confirmed cases, the medical resources, the humidity, and the population density significantly affect the CFR. Furthermore, the air quality and population density stand out in the first wave of epidemic outbreak, while they become non-significant in the second wave.
Cardiovascular Risk in Reproductive-aged Women With Polycystic Ovary Syndrome According to Body Mass Index: a Systematic Review and Meta-analysis

Background: To evaluate the association between cardiovascular risk and reproductive-aged women with polycystic ovary syndrome (PCOS) according to body mass index (BMI) categories.Methods: A literature search was conducted in MEDLINE, EMBASE, Cochrane Library and PubMed. Blood pressure (BP) [including systolic BP (SBP), diastolic BP (DBP) and hypertension prevalence] and plasma lipids [triglyceride, high-density lipoprotein (HDL)-cholesterol, nonHDL-cholesterol and low-density lipoprotein (LDL)-cholesterol] were calculated at different BMI levels.Results: SBP [MD (95% CI): 2.96 mmHg (1.62, 4.30), P < 0.001] and DBP [MD (95% CI): 1.64 mmHg (0.03, 3.24), P = 0.046] increased in reproductive-aged women with PCOS, however, hypertension prevalence had no difference [OR (95% CI): 1.56 (0.76, 3.06), P = 0.198]. HDL-cholesterol were [SMD (95% CI): -0.24 (-0.39, -0.09), P = 0.002] lower and triglyceride [SMD (95% CI): 0.37 (0.26, 0.48), P < 0.001] higher in reproductive PCOS women. Besides, LDL-cholesterol [SMD (95% CI): 0.25 (0.17, 0.34), P < 0.001] and nonHDL-cholesterol [SMD (95% CI): 0.38 (0.29, 0.47), P < 0.001] were higher in reproductive-aged PCOS. In the subgroup analysis, SBP and LDL-cholesterol were increased in BMI of < 25 kg/m2 and BMI of ≥ 30 kg/m2, but had no difference in BMI of 25-< 30 kg/m2. Triglyceride and nonHDL-cholesterol increased in all BMI categories. However, DBP and hypertension prevalence had no difference in all BMI categories.Conclusion: High baseline BP and dyslipidemia is represented in reproductive PCOS. Besides, reproductive PCOS women are significantly associated with increased cardiovascular risk independent of BMI categories.
THE EFFECTS OF IMPLICIT AND EXPLICIT CLASSROOM FEEDBACK ON BILINGUAL SPEECH PRODUCTION

Recent research on the role of classroom feedback has pointed out that learning is easier and quicker when students receive detailed feedback that tells them precisely what they have done wrong and what they should have done instead. Our study aimed to investigate how two different types of classroom feedback influence the development of bilingual oral production. Fifty-four English L2 learners were divided into an implicit feedback group and an explicit feedback group. Both groups were exposed to a two-month-hybrid experience for the development of oral production. The implicit group received implicit feedback based on the general content of their oral production. The explicit group received explicit feedback based on grammar, pointing out corrections in relation to the form of their oral production. Through a preand post-test, we verified whether the different types of feedback impacted the participants' oral production, in terms of grammatical accuracy, weighted lexical density and fluency. Results show that explicit feedback was more effective in improving learner ́s L2 grammatical accuracy after the two months of intervention. However, there were no significant differences between the two types of feedback in relation to developing lexical density or fluency over time.
The impact of out-of-home placement characteristics with regard to suicidal risk among adult survivors of childhood abuse

Background: Childhood abuse is associated with increased lifetime suicidal risk (SR). Among victims of abuse, children in out-of-home care are also at risk. Out-of-home placement is aimed at stopping further exposure to maltreatment and at providing the necessary security for proper development. Research suggests that placement arrangements may impact children’s mental health outcomes. Objective: The study was aimed at examining (1) the direct effects of different placement characteristics (i.e. age at first placement, number of placements, placement disruptions, total time in care, contact with biological parents, contact with siblings, placement with siblings) on SR and (2) whether these characteristics moderate the link between maltreatment and SR. Participants: The sample consisted of 77 adults (52 women; 25 men; mean age: 26.6 years) who received out-of-home care during childhood. Method: Participants completed the Childhood Trauma Questionnaire and the Mini International Neuropsychiatric Interview (for SR). Participants’ records were used to determine placement characteristics and maltreatment. Results: PLS-PM analyses suggest a significant role of risk (age at first placement, number of placements, placement disruptions, contact with biological parents) and protective factors (contact with siblings, foster home placement) on SR. Risk factors also moderate the link between maltreatment and SR. Conclusions: Interventions aimed at limiting risk factors during placement seem important to reduce SR.
Examining Home and International Students’ Awareness of, Attitudes Towards and Participation in Intercultural Activities on Campus

Internationalization in higher education and the promotion of intercultural interaction are becoming increasingly prevalent globally. Conducted in Hong Kong, this mixed-methods study investigated one facet of these initiatives, namely intercultural activities on campus. Both home (n = 305) and international (n = 127) students’ awareness of, attitudes toward, and participation in these activities were examined. The results showed that these three variables were significantly inter-correlated, and awareness and attitude together explained 36% of the variance in participation. While both groups had similar levels of awareness and participation, the international students were slightly more positive toward these activities than the home students were. Lack of time, absence of company, and uninteresting activities were found to be the top three reasons for low/no participation. Follow-up semi-structured interviews were conducted with 18 participants, who elaborated on awareness-raising promotion platforms for these activities, motivators, and demotivators for participation, and the general differences between home and international students. The article ends with a discussion on these findings.
Efficiency and Effect of Regulatory Policies on the Online Peer-to-peer (P2P) Lending Industry

ABSTRACT We investigated the influential power of regulatory policies on 463 peer-to-peer lending platforms in China to understand the effectiveness of their regulatory policies. Our results showed that the influence of regulatory policies varies across platforms. Notably, 1) the platforms controlled by the listed firms face more difficulties than others with strict supervision; 2) the platforms with little registered capital and a shorter period of establishment are more susceptible to regulatory policies; and 3) the platforms with a short duration of debt transfer have a greater risk of bank runs and serious fluctuations in trading volume due to the policy release.
Financial Literacy and the Perceived Value of Stress Testing: An Experiment Using Students in Brazil

ABSTRACT We run an experiment to test how consumers of banking services value stress tests performed by their banks. We query respondents about the extent to which they would be willing to trade profitability if banks conduct stress tests, maybe for greater bank financial stability. Our paper connects and innovates in the banking literature by providing empirical evidence of the value of communicating bank stress tests routines to the public from the consumer perspective rather than the regulator’s usual perspective or of the bank itself. By performing stress tests and communicating them to their customers, we find that consumers accept lower remuneration rates of their deposits, suggesting they value stress testing. Our experimental design also contains several queries to estimate the degree of financial literacy of respondents. By combining both perspectives, we find that respondents with higher financial literacy levels are more conservative and replace more profitable banks with less profitable banks that perform and communicate stress testing routines to the public. We explicitly consider measurement error in our data collection process of respondents’ rather subjective financial literacy indicator by introducing external instruments. Such consideration aims at mitigating attenuation bias. We also run several robustness tests with subsets of our sample and non-linear models, such as Probit.
Survey of ICU Teaching Rounds: Secrets to Improve Learner Satisfaction

Background: Unique challenges of teaching in the ICU come from the complexity of critically ill patients. This study was designed to examine the different teaching patterns and learners’ emotion load to achieve learners satisfaction on rounds. Methods: The survey of learners was performed on their practices and perceptions of rounds using social media. Results: A total of 82 learners with 195 responses were received. Pathophysiology-based analysis on worsened conditions, problem-based teaching and feedback, discussion about past experience were top three teaching behaviors on rounds, in addition, interesting and storytelling presentation, and evidence-based medicine were significantly correlated with learner satisfaction. However, the leaners still have the expectations for further improvement of some teaching behaviors. During rounding, tense, calm, nervous, relaxed and excited were the most top learners’ emotions, only excited was significantly correlated with learners satisfaction. Conclusions: Pathophysiology-based analysis on worsened conditions, problem-based teaching and feedback, discussion about past experience are top three teaching behaviors during the rounding, however, learners might be dissatisfied barely with these teaching pattens. Teachers should focus on key skills on rounds to enhance satisfaction.
