Analysis of prospective physics teacher misconceptions about friction force with three tier tests and clinical interviews

A good and correct understanding of concepts is a fundamental thing that prospective Physics teachers must have before graduated from college. Therefore, it is necessary to identify the conception to ensure that there are no students who have misconceptions and do not understand the concept. This study aims at identifying the misconceptions experienced by prospective Physics teachers at the final level, especially in the friction force material. This is descriptive research conducted in a university in Mataram with 12 students involved. The instrument used was a three-tier test in the form of a multiple-choice test with open reasons. A total of 10 items with 30 questions were used in this study. Data collection techniques used was tests and interviews. The data that has been collected was then analyzed using descriptive statistics. Based on the results of the data analysis, it was found that 46.29% of the students had misconceptions with details of 50.00% of the students experienced misconceptions in determining the type of friction force, 43.75% in determining the direction of friction force, and 47.22% in determining the magnitude of the friction force. The results of this study indicate that there are still many students of prospective Physics teachers have misconceptions. Therefore, we need an alternative learning that can be used to reduce the misconceptions had by prospective Physics teachers.
Phase angle as a screening method for sarcopenia in community-dwelling older adults

ABSTRACT Objective We investigated the utility of the phase angle as a screening tool for sarcopenia. Methods We performed a cross-sectional study that included 169 active community-dwelling elderly women. The phase angle was determined using tetrapolar bioelectrical impedance, and sarcopenia was diagnosed based on skeletal muscle mass, muscle strength, and physical performance using bioelectrical impedance analysis, a handheld dynamometer, and the gait speed test, respectively. Receiver operating characteristic curve analysis was performed to investigate the role of the phase angle as a predictor of sarcopenia. Results The prevalence of sarcopenia was 12.4%. The median phase angle was 5.30°; elderly women with sarcopenia had lower phase angles than those without sarcopenia (p=0.006). The phase angle cutoff for the detection of sarcopenia was ? 5.15°, with an area under the curve of 0.685, sensitivity 81.0%, specificity 60.8%, and accuracy 63.31%. Elderly women with a low phase angle show a high risk of presenting with reduced muscle mass. Conclusions The phase angle was shown to be a useful screening tool in elderly women with sarcopenia.
Absence of Vitamin D Deficiency Among Outdoor Workers With Type 2 Diabetes Mellitus in Southern West Bengal, India

Background: Vitamin D deficiency is widespread globally and is associated with type 2 diabetes mellitus (T2DM). Studies suggest markedly lower prevalence of vitamin D deficiency in outdoor workers compared to indoor workers. However, data on the vitamin D status of outdoor workers with T2DM is lacking. Aims: We assessed the vitamin D status of outdoor workers with T2DM residing across several districts of Southern West Bengal, India. Design: The present study is a descriptive observational study. Material and methods: A total of 128 outdoor workers with T2DM were assessed for serum 25-hydroxyvitamin D (25(OH)D) during December 2019 after excluding common confounders except sun exposure (which was detailed using a questionnaire). Hospital staff were indoor controls, and vitamin D status was classified as per the Institute of Medicine guidelines. Results: The mean serum 25(OH)D of outdoor workers with T2DM was 21.79 ± 6.31 ng/mL, with only 2.34% (n = 3) having vitamin D deficiency and 57.03% (n = 73) having sufficient serum 25(OH)D levels. The mean serum 25(OH)D of indoor controls was significantly lower at 16.67 ± 9.82 ng/mL (p = 0.003), with 33.33% being vitamin D deficient. Serum 25(OH)D in outdoor workers with T2DM did not have a significant correlation with indices of sun exposure. Conclusions: Vitamin D deficiency is practically absent in outdoor workers with T2DM residing in Southern West Bengal, India.
Single-Island Endemism despite Repeated Dispersal in Caribbean Micrathena (Araneae: Araneidae): An Updated Phylogeographic Analysis

Island biogeographers have long sought to elucidate the mechanisms behind biodiversity genesis. The Caribbean presents a unique stage on which to analyze the diversification process, due to the geologic diversity among the islands and the rich biotic diversity with high levels of island endemism. The colonization of such islands may reflect geologic heterogeneity through vicariant processes and/ or involve long-distance overwater dispersal. Here, we explore the phylogeography of the Caribbean and proximal mainland spiny orbweavers (Micrathena, Araneae), an American spider lineage that is the most diverse in the tropics and is found throughout the Caribbean. We specifically test whether the vicariant colonization via the contested GAARlandia landbridge (putatively emergent 33–35 mya), long-distance dispersal (LDD), or both processes best explain the modern Micrathena distribution. We reconstruct the phylogeny and test biogeographic hypotheses using a ‘target gene approach’ with three molecular markers (CO1, ITS-2, and 16S rRNA). Phylogenetic analyses support the monophyly of the genus but reject the monophyly of Caribbean Micrathena. Biogeographical analyses support five independent colonizations of the region via multiple overwater dispersal events, primarily from North/Central America, although the genus is South American in origin. There is no evidence for dispersal to the Greater Antilles during the timespan of GAARlandia. Our phylogeny implies greater species richness in the Caribbean than previously known, with two putative species of M. forcipata that are each single-island endemics, as well as deep divergences between the Mexican and Floridian M. sagittata. Micrathena is an unusual lineage among arachnids, having colonized the Caribbean multiple times via overwater dispersal after the submergence of GAARlandia. On the other hand, single-island endemism and undiscovered diversity are nearly universal among all but the most dispersal-prone arachnid groups in the Caribbean.
Molecular Dynamics in the Study and Development of Molecularly Imprinted Materials – Status Quo, Quo Vadis?

The past two decades have witnessed the introduction of and then a steady increase in the use of computational techniques in the study and development of molecularly imprinted polymers (MIPs). Molecular dynamics (MD) based studies have had a significant role in this development as they can provide insights concerning the mechanisms governing the molecular level events underlying MIP synthesis and MIP-ligand interactions and can be used for the identification of preferred monomer compositions and for the prediction of MIP properties. We here review the role that MD has played in the development of molecular imprinting and examine the different types of MD strategies that have been used, including their advantages and challenges. Recent trends in the application of MD to the study of MIPs are presented, along with a perspective on the future importance of MD-based studies for the development of molecular imprinting science and technology.
Inhomogeneous spin excitations in weakly coupled spin-
12
 chains

We present a systematic inelastic neutron scattering and neutron diffraction study of the magnetic structure of the quasi-1D spin-1/2 magnet SrCo2V2O8, where the interchain coupling in the Neel-type antiferromagnetic ground state breaks the static spin lattice into two independent domains. At zero magnetic field, we observe two new spin excitations with small spectral weights inside the gapped region defined by the spinon bound states. In an external magnetic field along the chain axis, the Neel order is partially destabilized above 2 T and completely suppressed at 3.9 T, above which a quantum disordered Tomonaga-Luttinger liquid (TLL) prevails. We propose that the two new modes at zero field are spinon excitations inside the domain walls. Since they have a smaller gap than those excited in the Neel domains, the underlying spin chains enter the TLL state via a local quantum phase transition at 2 T, making a stable Neel / TLL coexistence until the excitation gap closes in the Neel state at 3.9 T.
Physical intimate partner violence in India: how much does childhood socialisation matter?

ABSTRACT While a large number of studies assumed gendered socialisation leads to partner abuse, little evidence exists for India. We bridge this crucial gap by exploring the pathways between childhood socialisation and intimate partner violence, using data from ‘Youth in India: Situation and Need Study (2006–2007)’ for 5573 young married men (15–29 years). Nearly 17 per cent of men inflicted physical IPV in the past 12 months. Seventy-seven per cent recognized the experience of gender discrimination in their family and reported exposure to violence in two ways—one-third witnessed fathers abusing their mothers and 48 per cent were beaten by their parents. Adverse childhood experiences were associated with IPV perpetration. The structural equation model indicated significant pathways between IPV and childhood socialisation in the forms of experienced violence and gender discrimination. Findings underscore the importance of a violence-free, gender-neutral family environment for young generations and call for a comprehensive policy to ameliorate the impacts of IPV.
A comprehensive review of the articles published in the field of health in emergencies and disasters in Iran

Introduction Iran is one of the most disaster-prone countries in the world. A research-based approach is essential to reduce the effects of disasters and provide effective responses. This study aims to review the articles published in the field of emergencies and disasters in Iran. Methods a combination of descriptive and qualitative content analysis using Hsieh and Shannon´s method was done. Since the first and most well-known specialized journal in the field of emergencies and disasters in Iran is the Health in emergencies and Disasters Quarterly (HDQ), all articles published in this journal were examined in terms of theme and scientometric indicators. Results regarding the type of research, 103 were quantitative (66.5%), 18 were qualitative (11.6%), and 4 (2.6%) were performed by mixed method. Most of the articles (n=116, 76.3%) were original research. The most frequently studied risk was traffic accidents (n=17, 10.96%) followed by earthquakes (n=10, 6.45%) and floods (n=8, 5.16%). In terms of theme and content, 103 published articles were related to one of the 4 main phases of the disaster risk management cycle where most of them were related to preparedness (n=48, 46.6%) followed by mitigation (n=26, 25.24%), response (n=20, 19.42%), and recovery (n=9, 8.47%) phases. Conclusion although there are studies related to the four phases of disaster risk management cycle in Iran, most of them are related to assessing preparedness followed by mitigation. In addition, qualitative and mixed studies could have more significant contribution to this field of research, accelerating this process requires the development of disaster research methodology training and researcher training programs as well as their organized and financial support.
Dilated cardiomyopathy mutation E525K in human beta-cardiac myosin stabilizes the interacting-heads motif and super-relaxed state of myosin

The auto-inhibited, super-relaxed (SRX) state of cardiac myosin is thought to be crucial for regulating contraction, relaxation, and energy conservation in the heart. We used single ATP turnover experiments to demonstrate that a dilated cardiomyopathy (DCM) mutation (E525K) in human beta-cardiac myosin increases the fraction of myosin heads in the SRX state (with slow ATP turnover), especially in physiological ionic strength conditions. We also utilized FRET between a C-terminal GFP tag on the myosin tail and Cy3ATP bound to the active site of the motor domain to estimate the fraction of heads in the closed, interacting-heads motif (IHM); we found a strong correlation between the IHM and SRX state. Negative stain EM and 2D class averaging of the construct demonstrated that the E525K mutation increased the fraction of molecules adopting the IHM. Overall, our results demonstrate that the E525K DCM mutation may reduce muscle force and power by stabilizing the auto-inhibited SRX state. Our studies also provide direct evidence for a correlation between the SRX biochemical state and the IHM structural state in cardiac muscle myosin. Furthermore, the E525 residue may be implicated in crucial electrostatic interactions that modulate this conserved, auto-inhibited conformation of myosin. Significance Statement Dilated cardiomyopathy can be caused by single point mutations in cardiac muscle myosin, the motor protein that powers contraction of the myocardium. We found that the E525K DCM mutation in the cardiac myosin heavy chain stabilizes the auto-inhibited, super-relaxed state, suggesting a mechanism by which this mutation reduces muscle force and power. The E525K mutation also highlights critical electrostatic interactions important for forming the conserved, auto-inhibited conformational state of striated muscle myosins.
Metastatic role of galectin-1 in neuroendocrine cervical cancer

Cervical cancer is ranked top ten in the ranking of female cancer and the metastasis of cervical cancer is one of the main causes of decreasing five-year-survival rates. Neuroendocrine cervical cancer belongs to rare type of cervical cancer and is one of the more malignant cancer type, compared to squamous cell carcinoma and adenocarcinoma. In the previous work, we have carried out proteomics-based 2D-DIGE and MALDI-TOF-MS to analyze the differentially modulated proteins in neuroendocrine cells (HM-1) and other types of cervical cancer cells (Caski, ME-180, HeLa). In which, galectin-1 (LGALS1) was selected as the candidate protein due to high expression of LGALS1 in HM-1 cells. In this study, use small interfering RNA (siRNA) to knockdown LGALS1 expression in HM-1and HM-2 which isolated from human tissue. The migration ability and proliferation ability of neuroendocrine cervical cancer cells are effectively inhibited. Also, the de-regulation of cell cycle progression was observed during LGALS1 silencing. As a result, LGALS1 affects the migration and proliferation ability in neuroendocrine cervical cancer. The protein is potential to be a candidate to detect and treatment of neuroendocrine cervical cancer.
Supply Chain Management Strategy and Capital Structure of Global Information and Communications Technology Companies

Supply chain management (SCM) plays an important role in international work distribution mechanisms. This phenomenon has shifted to an SCM-to-SCM competition rather than corporate-to-corporate competition in the global market. Apple and Samsung Electronics are the two major global information and communications technology (ICT) companies, each choosing different SCM strategies to stabilize production while minimizing inventory and maintaining ongoing partnerships with suppliers. To analyze the relationship between strategic differences in SCM structure of the ICT companies and capital, while employing the generalized method of moments, this study analyzed partnerships with suppliers from a financial perspective for long-term growth and stable production. Results identified that the target debt ratio of Apple’s parts suppliers was 38%, which was slightly higher than that of US companies (33%). In the relationship between capital structure and SCM structures, the company’s debt ratio decreases if the strength of the strategic alliance and the strength of the horizontal integration of global parts suppliers are higher. Specifically, Apple’s parts suppliers with non-equity alliances, such as technological and R&D alliances, have reduced debt ratios more than companies with equity alliances. In the case of Samsung Electronics’ parts suppliers, primary vendors had a lower debt ratio than secondary vendors. These results indicates that if the strength of the vertical integration with the international strategic alliances is greater, they are more likely to adopt a lower debt ratio policy. Identifying the relationship between SCM strategic difference and capital structure, this study provides valuable insights for corporate sustainability.
Identifying Barriers to Mental Health Help-Seeking in French University Students during the Covid-19 Pandemic

The Covid-19 pandemic has dramatically impacted university student’s mental health, a population already known to be vulnerable for developing mental disorders and to demonstrate poor help-seeking behaviours for their mental health. Identifying why university students may choose not to seek help event if needed is an important step towards facilitating early access to mental health services and improving psychological wellbeing. This study aims to investigate help-seeking behaviour and barriers to help-seeking in university students. In December 2020, 182 students from a French university in Bourgogne Franche-Comté participated in an online survey that measured help-seeking behaviours and barriers to accessing mental help. Results showed that 63% of participants reported they would not seek any formal or informal help if dealing with an emotional or mental health difficulty. Most of students reported a preference toward informal help from friends and family compared to help form professionals. Seeking mental health-related information and support on the internet was also a relatively common behaviour. University students perceive a number of barriers to help-seeking for mental health problems. These include a preference for self-reliance, poor emotional competence and mental health literacy, and cost and time constraints. We discussed how the results of the present survey provide crucial information for policymakers to adopt strategies for improving help-seeking by university students.
KNOWLEDGE MANAGEMENT AND ORGANIZATIONAL PERFORMANCE OF SELECTED DEPOSIT MONEY BANKS IN NIGERIA

This study examined knowledge management and organizational performance of selected deposit money banks in Nigeria. Specifically it determines the relationship between them and hence the effect of knowledge acquisition, knowledge conversion, knowledge application and knowledge protection on the performance of deposit money banks in Nigeria. In pursuance of the above, the study employs the survey research design. Data was obtained from the employees of the five banks by simple random sampling technique method. Taro Yamane’s formula was used to determine the sample size of 400 respondents. Proportionate representation was used to get the 400 respondents since the number of employees was not the same in each of the five banks. Data analyzed was subjected to simple percentage, descriptive statistics, and normality test. Correlation and OLS linear regression analysis was also carried out. The result revealed that knowledge acquisition practices have significant positive relationship on performance by deposit money banks in Nigeria, that knowledge conversion practices have significant positive relationship with performance of deposit money banks in Nigeria, that knowledge application practices have significant positive relationship with performance of deposit money banks in Nigeria and knowledge protection practices have significant positive relationship with performance of deposit money banks in Nigeria. The contributions to knowledge were that the study affirmed knowledge acquisition facilitates organizational performance through its increased marketing effort, that knowledge conversion enhances organizational performance by way of expertise and efficiency, that knowledge application helps in the area of better risk management and that knowledge protection enhances competitive advantage of the organization. The study demonstrated a hybrid of resourced based theory and left brain and right brain management theory. The study recommends among others that deposit money banks should encourage knowledge conversion practices so that their performance will improve.
Examining the Associations between COVID-19-Related Psychological Distress, Social Media Addiction, COVID-19-Related Burnout, and Depression among School Principals and Teachers through Structural Equation Modeling

This study aims to investigate the relationships between COVID-19-related psychological distress, social media addiction, COVID-19-related burnout, and depression. The research, which was designed according to the relational survey model, was conducted with the participation of 332 school principals and teachers who received graduate education in the field of educational administration. Research data were collected through online surveys and then structural equation modeling (SEM) was used to test and analyze the proposed hypotheses. The study’s findings revealed that COVID-19-related psychological distress strongly predicted COVID-19-related burnout. In this context, as the psychological distress associated with COVID-19 increased, the sense of burnout associated with COVID-19 also increased. However, it was found that burnout associated with COVID-19 significantly and positively predicted depression. SEM results revealed that COVID-19-related psychological distress directly affected COVID-19-related burnout, depression, and social media addiction. In addition, it was determined that an indirect effect of COVID-19-related burnout and social media addiction exists in the relationship between COVID-19-related psychological distress and depression.
