Authors: Nigussie Likimyelesh , Minh Thai Thi , Senaratna Sellamuttu Sonali 
Published: May 2024

Abstract
Many countries in Sub-Saharan Africa (SSA) have made youth inclusion a top priority in their development agendas. This is aimed at overcoming social, technical, and institutional obstacles and providing fair and significant opportunities for the growth of young people. Inclusive agricultural value chain development (VCD) is being used to address youth unemployment in the region. The Nigerian government and its partners have invested in aquaculture VCD to create employment opportunities for young men and women, but the participation rate is low, at around 2%. Further, research and practices focusing on rural youth inclusion in VCD is scant, with biases towards urban youth inclusion. This study explored youth engagement in the aquaculture value chain and how the chain features and context shape inclusive mechanisms/patterns of youth inclusion in VCD processes. We used the integrated livelihood asset framework, access approach, and VCD approaches to present an analysis of conditions influencing the inclusion of young men and women in the aquaculture VCD in Nigeria. Accordingly, two youth inclusion strategies were identified: investment and risk management strategies. Young men and women from better-off households adopt investment strategy and dominate the production function. They use their resources, social networks and support from youth-focused aquaculture projects to invest in production functions. Those adopting a risk management strategy dominate the processing, distribution, and marketing functions. They dominantly use social networks, support from aquaculture projects, and Information Communication Technologies (ICTs) to mitigate risks. The high demand for fresh and processed fish, supportive policies, and youth-centered aquaculture projects encourages the engagement of young men and women to adopt either of the strategies. However, they face challenges such as high-cost and low-quality inputs, lack of tailored services, inadequate infrastructure, and sociocultural norms. This study contributes to youth inclusion literature, provides a comprehensive theoretical lens for understanding youth inclusion in VCD, and offers insights into the specific case of young men and women’s engagement in the aquaculture sector in Nigeria.
Biotechnology towards energy crops
Authors: Dida Gudeta 
Published: May 2024

Abstract
Our world is experiencing an unprecedented surge in energy demand due to rapid economic growth and population expansion. This escalating need for energy poses a significant challenge as reliance on fossil fuels leads to severe environmental pollution. Consequently, the exploration of renewable energy sources, such as biofuels, emerges as a prudent solution to mitigate the energy crisis. The cultivation of novel crops and the implementation of advanced cultivation systems are gradually gaining traction, aiming to minimize dependence on depleting fossil fuel reserves and foster resilience to global climate change. These promising biological resources hold immense potential as bioenergy feedstocks, offering a versatile and sustainable means to meet the energy requirements of modern society on a daily basis. Biotechnology, in particular, can play a critical role in developing superior genotypes of energy crops, specifically tailored for efficient bioprocessing and subsequent utilization. By applying cutting-edge molecular techniques, a wide range of important traits can be enhanced, encompassing total biomass yield, production, quality, and resistance to different biotic and abiotic stresses. These advancements have the potential to significantly improve the efficiency, cost-effectiveness, and environmental benefits of biofuels. This comprehensive review aims to evaluate the potential of biotechnological applications in the development of advantageous bioenergy crops, spanning from feedstock enhancement to sustainable biofuel production. Furthermore, it provides compelling examples of cutting-edge research in the field, showcasing the prospects of energy crop innovation.
Trade Secret Protection and the Integration of Information Within Firms
Authors: Andreicovici Ionela , Bormann Sara , Hombach Katharina 
Published: May 2024

We examine the effect of trade secret protection laws on internal information integration (i.e., the extent to which economic agents are provided with access to decision-relevant information from other economic agents within a firm). We argue that stronger trade secret protection laws increase firms’ internal information integration because they reduce the proprietary costs of information leakage. To test our prediction, we measure a firm’s internal information integration by the share of its sites integrated into its enterprise management system. Exploiting the staggered adoption of trade secret protection laws via the Uniform Trade Secrets Act (UTSA), we find that these laws increase firms’ internal information integration. This effect is stronger (weaker) for firms with higher proprietary costs (coordination benefits). Further, we provide evidence that the UTSA-induced increase in internal information integration translates into improvements of firms’ internal information quality and decision-making quality. Taken together, our results enhance the understanding of the economic trade-offs shaping firms’ internal information environment. This paper was accepted by Ranjani Krishnan, accounting. Funding: S.

Bank Specialization and Zombie Lending
Authors: De Jonghe Olivier , Mulier Klaas , Samarin Ilia 
Published: May 2024

We study whether banks internalize congestion externalities when lending to zombie firms. We conjecture that banks should be better informed about the presence of zombie firms and the congestion externalities that such firms exert on healthy borrowers in industries where banks are specialized and show that banks’ credit supply to zombie firms relates negatively to their industry specialization. This relation is stronger when congestion externalities are likely to have stronger adverse effects, namely when zombie firms take a higher fraction of resources in the industry or when the industry is geographically more concentrated. Additionally, this relation is weaker in industries with higher asset specificity as zombie firms’ default (and potential asset fire sales) could reduce healthy borrowers’ collateral value.

The Double-Edged Sword of Exemplar Similarity
Authors: Majzoubi Majid , Zhao Eric Yanfei , Zuzul Tiona , Fisher Greg 
Published: May 2024

We investigate how a firm’s positioning relative to category exemplars shapes security analysts’ evaluations. Using a two-stage model of evaluation (initial screening and subsequent assessment), we propose that exemplar similarity enhances a firm’s recognizability and legitimacy, increasing the likelihood that it passes the initial screening stage and attracts analyst coverage. However, exemplar similarity may also prompt unfavorable comparisons with exemplar firms, leading to lower analyst recommendations in the assessment stage. We further argue that category coherence, distinctiveness, and exemplar typicality influence the impact of exemplar similarity on firm evaluation. Leveraging natural language processing (NLP) techniques to analyze a sample of 7,603 U.S. public firms from 1997 to 2022, we find robust support for our predictions. By highlighting the intricate role of strategic positioning vis-à-vis category exemplars in shaping audience evaluations, our findings have important implications for research on positioning relative to category exemplars, category viability, optimal distinctiveness, and security analysts.

Authors: Scoglio Arielle A. J. , Nishimi Kristen , Choi Karmel W. , Koenen Karestan C. , Sampson Laura A. , Jha Shaili C. , Kubzansky Laura D. 
Published: May 2024

Background and objective
This study examined the potential influence of pre-pandemic psychological resilience on use of approach or avoidant coping styles and strategies to manage stress during the COVID-19 pandemic. We hypothesized that higher resilience would be associated with more approach coping and less avoidant coping.

Design and methods
Longitudinal cohort data were from the Nurses’ Health Study II, including 13,143 female current and former healthcare professionals with pre-pandemic lifetime trauma. Pre-pandemic resilience was assessed between 2018–2019 and current coping during the outbreak of the pandemic in the United States (May-August 2020). Multiple linear regression model results identified associations between continuous pre-pandemic resilience scores and use of approach and avoidant coping styles, as well as individual coping strategies, adjusting for relevant covariates.

Results
Greater resilience was associated with higher use of approach coping (ß = 0.06, 95% CI 0.05, 0.08) and lower use of avoidant coping styles (ß = -0.39, 95% CI -0.41, -0.38). Higher pre-pandemic resilience was also associated with use of eight (distraction [ß = -0.18, 95% CI -0.20, -0.16], substance use [ß = -0.15, 95% CI -0.17, -0.13], behavioral disengagement [ß = -0.29, 95% CI -0.30, -0.27], self-blame [ß = -0.44, 95% CI -0.45, -0.42], emotional support (ß = 0.03, 95% CI 0.01, 0.05), positive reframing [ß = 0.13, 95% CI 0.12, 0.15], humor [ß = 0.03, 95% CI 0.01, 0.05] and religion [ß = 0.06, 95% CI 0.04, 0.08]) of the nine coping strategies in expected directions.

Conclusion
Findings have important implications for intervention or even prevention efforts to support vulnerable groups, such as women with prior trauma histories, during this and other immensely stressful times. Supporting or building psychological resilience following trauma may promote effective coping in times of future stress.

Published: May 2024

Background
Benefit finding has become a central construct in the evolution of positive psychology and attracted attention in recent literature. This study aimed to translate and validate the General Benefit Finding Scale (GBFS) in Chinese college students.

Methods
Forward- and back-translation of the GBFS was followed by the assessment of semantic equivalence and content validity. A sample of 589 college students was recruited in China to conduct reliability and validity analysis. The construct validity was assessed using exploratory (EFA) and confirmatory factor analysis (CFA). Concurrent validity was assessed using Pearson’s correlation coefficients of the GBFS with the Perceived Stress Scale (PSS) and World Health Organization-Five Well-Being (WHO-5). Internal consistency and two-week test-retest reliability were also evaluated.

Results
The content validity index for each item ranged from 0.83 to 1.00. EFA revealed a six-factor model, which exhibited acceptable goodness of fit in CFA (standardized root mean square residual = 0.031, root mean square error of approximation = 0.059, goodness-of-fit index = 0.860, comparative fit index = 0.904, Tucker-Lewis index = 0.890, chi-squared/degree of freedom = 2.07). The concurrent validity of the GBFS was supported by its statistically significant correlations with PSS (r = –0.271, p<0.001) and WHO-5 (r = 0.354, p<0.001). Moreover, the internal consistency for the overall scale was satisfactory, with Cronbach’s α coefficient of 0.93 and McDonald’s omega reliability of 0.94. The test-retest reliability was 0.82.

Conclusions
Although the Chinese version of GBFS was examined in a homogeneous convenience sample of college students, it provides a reliable and valid instrument for assessing benefit finding in the Chinese context.
Inverse association of the systemic immune-inflammation index with serum anti-ageing protein Klotho levels in individuals with osteoarthritis: A cross-sectional study
Authors: Zhao Jinlong , Lai Yinhua , Zeng Lingfeng , Liang Guihong , Jin Xiao , Huang Hetao , Luo Minghui , Liu Jun 
Published: May 2024

Background
The association between the systemic immune-inflammation index (SII) and the serum soluble-Klotho concentration (pg/ml) in osteoarthritis (OA) patients is unknown. This study aimed to investigate the relationship between the SII and serum soluble-Klotho levels in OA patients.

Methods
All study data were obtained from the National Health and Nutrition Examination Survey (NHANES) database (n = 1852 OA patients; age range = 40–79 years). The SII and serum Klotho measurement data are from the NHANES mobile examination centre. The SII values were divided into quartiles (Q1-4: 0.02–3.36, 3.36–4.78, 4.79–6.70, and 6.70–41.75). A multivariate linear regression model was constructed to evaluate the association between the SII and serum Klotho levels in OA patients; interaction tests were conducted to test the stability of the statistical results.

Results
Multivariate linear regression revealed a negative linear relationship between the SII and serum Klotho concentration in OA patients (β = -6.05; 95% CI: -9.72, -2.39). Compared to Q1, Q4 was associated with lower serum Klotho concentrations (β = -59.93; 95% CI: -96.57, -23.28). Compared with that of Q1, the β value of Q2-Q4 showed a downwards trend as the SII increased (Ptrend <0.001). The stratified analysis results indicated that the SII had a greater sensitivity in predicting serum Klotho concentrations in OA patients aged 60–79 years (Pinteraction = 0.028).

Conclusions
There was a significant negative linear correlation between the SII and serum Klotho concentration in OA patients. The SII can serve as a predictive indicator of serum Klotho concentrations in OA patients. Klotho may be a potential anti-inflammatory drug for OA treatment.
Heart Transplantation in a Patient With Rheumatic Heart Disease and Severe Left Atrial Calcification
Authors: Song Kyungsub , Lee Seonhwa , Kim Yun Seok 
Published: May 2024

Abstract
A 62-year-old woman who had undergone mitral valve replacement 24 years ago was admitted to the hospital with congestive heart failure. She needed heart transplantation for stage D heart failure. Preoperative cardiac computed tomographic scans showed a severely calcified left atrium and a large right atrium. Given that the left atrium's calcification was too severe to suture, the calcified left atrial wall was broadly resected, and the resected left atrial wall was reconstructed with a bovine pericardial patch for anastomosis with the donor's left atrial wall. The operation was completed without heavy bleeding, and the patient was discharged from the hospital with no complications.
A switching lung mechanics model for detection of expiratory flow limitation

Published: May 2024

Abstract
Expiratory flow limitation (EFL) is an often unrecognized clinical condition with a multitude of negative implications. A mathematical EFL model is proposed to detect flow limitations automatically. The EFL model is a switching one-compartment lung mechanics model with a volume-dependent airway resistance to simulate the dynamic behavior during expiration. The EFL detection is based on a breath-by-breath model parameter identification and validated on clinical data of mechanically ventilated patients. In the severe flow limitation group 93.9 % ± 5 % and in the no limitation group 10.2 % ± 13.7 % of the breaths are detected as EFL. Based on the high detection rate of EFL, these results support the usefulness of the EFL detection. It is a first step toward an automated detection of EFL in clinical applications and may help to reduce underdiagnosis of EFL.

Published: May 2024

Abstract
In recent years, robotic arm exoskeletons have emerged as promising tools, finding widespread application in the rehabilitation of neurological disorders and as assistive devices for everyday activities, even alleviating the physical strain on labor-intensive tasks. Despite the growing prominence of exoskeletons in everyday life, a notable knowledge gap exists in the availability of open-source platforms for classroom-ready usage in educational settings. To address this deficiency, we introduce an open-source educational exoskeleton platform aimed at Science, Technology, Engineering, and Mathematics (STEM) education. This platform represents an enhancement of the commercial EduExo Pro by AUXIVO, tailored to serve as an educational resource for control engineering and biomedical engineering courses.
Analysis of undergraduate chemistry students’ responses to substitution reaction mechanisms: a road to mastery

Published: May 2024

Abstract
This study analyzed third-year undergraduate Chemistry major students’ drawings and written explanations of substitution reactions. Seventy (70) students were purposively selected for this study. The main data collection instrument was a diagnostic test and students’ responses were analyzed using deductive coding. The study aimed to unearth students’ conceptual understanding and difficulties on substitution reactions to provide significant insights into improving teaching strategies and learning outcomes. The findings revealed that: 1. Students were more familiar with SN2 reaction mechanisms and could answer questions on SN2 reaction mechanisms better than SN1 reaction mechanisms; 2. Students’ use of ‘chemical vocabulary’ did not translate into an understanding of electron movement and causal mechanistic explanation; 3. About 97 % of the students who gave a correct/partially correct description provided a description of what was happening in the reaction without any further explanation of why the reaction occurred; 4. Students had a slightly better understanding of drawing the correct mechanisms than providing accurate explanations. This study recommends that, in teaching organic reaction mechanisms, instructors should emphasize on electron-pushing formalisms and explain how and why reactions occur to encourage mechanistic thinking in students. Also, students should be given ample practice in organic reaction mechanisms to improve mastery.
Preferences, Institutions, and Policy Makers: The Case of the New Institutionalization of Science, Technology, and Innovation Governance in Colombia
Authors: Pardo Martínez Clara Inés , Cotte Poveda Alexander 
Published: May 2024

Abstract
Science, technology, and innovation (STI) are fundamental elements for achieving development and sustainable growth. Developing STI is also currently the main challenge faced by countries, especially those with emerging economies, making it essential that these countries implement comprehensive policies to generate a knowledge-based society. Institutions and policy-makers are responsible for defining the rules by which a society is governed. In particular, it is widely held that institutions should place special emphasis on establishing property rights, legal systems, customs, and the political systems based on which central planners should govern. From this perspective, this study integrates qualitative and quantitative analysis through a preference model with three types of STI policy-makers and projections to better clarify the requirements for new STI institutions in Colombia. It does so by using the time series of STI spending generated by the Administrative Department of STI (Colciencias) from 1968 to 2018. The simulation results show that among the chosen agents, the STI policy preferences of the scientist-manager yield economic outcomes closest to the optimal level. In contrast, the yield of the politician’s preferences is suboptimal and even negative at certain points. These results have implications for public policy, as poor policy choices may lead to undesirable results in terms of STI policy application, implementation, and execution. These findings are important for strengthening STI policy. They also indicate the important role of the government in transforming Colombia from being a receiver of technology to being a generator of knowledge, technology, and innovation in line with the requirements of the country’s population and its natural resource endowments.
Pelvic joint stiffness and fear of falling in patients over 75 years of age: a prospective cohort study of 100 patients
Authors: Laizeau Chloe , Jochmans Sebastien , Aufaure Sylvie 
Published: May 2024

Abstract

Context
A third of the population aged 65 and over experiences a fall during a given year, often with severe traumatic consequences, dependence, and consequently, a decline in quality of life. The fear of falling itself leads to avoidance behavior from daily activities leading to a downward spiral of dependence, loss of confidence, and therefore an increased risk of falling. Joint stiffness is often observed during clinical examination of elderly people. However, the association between lumbopelvic stiffness and fear of falling has not been studied.

Objectives
Osteopathic manipulative treatment/medicine (OMT/OMM), targeted to improve the stiffness of the pelvic girdle, may improve the prognosis of patients afraid of falling and slow down their loss of autonomy.

Methods
We performed a prospective cohort study enrolling hospitalized patients and nursing home residents over 75 years of age. Patients able to walk and without significant cognitive impairment completed the International Fall Efficacy Scale (FES-I) questionnaire to assess their intensity of fear of falling. The modified Schober test and hip goniometry (flexion and extension) were measured and compared to the FES-I score.

Results
A total of 100 patients were included. A high fear of falling (FES-I≥28) was associated with female sex (31 [79.5 %] vs. 29 [47.5 %]; p=0.002) and with a reduction in the amplitudes tested by the Schober test (2 [1.5–3] vs. 3 [2–4]; p=0.002), the hip extension goniometry (7 [4–10] vs. 10 [7–15]; p<0.001) and the hip flexion goniometry (70 [60–77] vs. 82 [71–90]; p<0.001). The association between FES-I score and each anthropometric variable was strongly linear (p<0.001 for all), especially with hip flexion goniometry (R2=30 %).

Conclusions
Lumbopelvic stiffness, especially in hip flexion, is strongly associated with a high fear of falling in patients over 75 years of age. When combined with other movement-based therapies, OMM targeted to improve the stiffness of the pelvic girdle may improve the prognosis of patients afraid of falling and slow down their loss of autonomy.
