Social Music Curation That Works

Social interactions, such as sharing songs and listening together, are fundamental to the experience of music. Yet our understanding of these interactions and how they influence social dynamics with today's streaming platforms is lacking. To better understand successful instances of social music practice, we conducted a two-part study to investigate real-world usage of collaborative playlists (CPs). Using an exploratory survey, we queried CP users on characteristics---Who, What, When, Where, Why, and How---and practices around favorite CPs, which serve as concrete examples of successful social music curation on streaming platforms. We found these playlists to vary in group sizes, purposes, listening contexts, engagement behaviors, and content attributes. We also observed significant cross-category interactions; for one, group size led to differences in perceived roles and frequency of actions within users' favorite CPs. Subsequent interviews confirmed favorite CPs as being exemplary of success, and users further elucidated factors that engender and hinder CP success. Together, our results underscore the importance of social motivations for engaging in CPs and of building greater understanding around these experiences. To these point we derived six design implications to inform development of CP platforms and online music platforms at large.
Effect of Cost Control Systems on Performance of Medium Scale Enterprises in Kericho Town

Costing control systems is not only crucial but also specific in any production and services rendered in any business irrespective of the enterprise. This is because it is an important instrument for business operation used by management in undertaking crucial decisions, helps to facilitate and manage information to improve management. It is therefore a significant insight in the determination of earnings, boom, growth, and development of organizations and business enterprises. Despite the role of Costing control systems, it’s effectiveness in MSEs is not clear thus the need to carry out the study. The purpose of the study is to investigate the effect of cost control systems on performance of medium scale enterprises. The understanding of the relationship between the two components of costing control system will enable the medium-scale evaluate their performance and instruct their employees to work according to the plan and provide a basis of control as well as help the government to design the best strategies for the sector. The research design was a cross-sectional study and adopted a survey research design. The target population was the 313 medium scale enterprises within Kericho town. Using Kothari's (2004) formula of the finite population the sample of 173 medium scale enterprises were selected. Questionnaires and data extraction forms was the main research tools of data collection. The key informants included the business’ finance, operation, and accounts manager/director. The questionnaires were tested and retested using Cronbach's Alpha for reliability and experts' opinions was sought to ensure instrument validity. The data obtained were analysed using Ordinary Least Squares Regression Analysis at a 5% significance level. Based on the results from the regression analysis, it was established that the selected costing control systems classified as independent variables accounts to 99.9% of the variance in the business performance. It can be deduced that costing control systems have an impact on medium scale enterprises performance therefore crucial for the implementation of the systems for effective performance. Costing control systems has a positive impact on performance (p = .000, p<0.05), this means that increased use of costing systems will improve performance of medium scale enterprise. Conclusions were made that the costing control system has significant effect on the performance of medium scale enterprise. The study recommended for implementation of these costing control systems for effective performance in the enterprises.
Preliminary Assessment of Ground Motion Duration Effects on Structural Collapse

SUMMARY: The 2010 M8.8 Chile and 2011 M9.0 Tohoku earthquakes are reminders of the potential for large magnitude earthquakes to produce ground motions with long durations. While it is generally recognized that long duration ground motions are more damaging than shorter duration motions, previous research on duration effects are inconclusive, and current design practice does not explicitly consider duration effects. This paper summarizes preliminary results of a study to assess the significance of ground motion duration effects on structural collapse. First, the findings of a preliminary investigation to identify the ideal duration metric for the evaluation of structural response are described, where the ideal duration metric is one which is uncorrelated from spectral acceleration and free from peculiarities in response spectra and acceleration record characteristics. Finally, the effects of ground motion duration on the collapse capacity of a 3-story steel special concentrically braced frame are presented.
Fusobacterium nucleatum is associated with inflammation and poor survival in early-stage HPV-negative tongue cancer

Abstract Persistent pathogen infection is a known cause of malignancy, although with sparse systematic evaluation across tumor types. We present a comprehensive landscape of 1060 infectious pathogens across 239 whole exomes and 1168 transcriptomes of breast, lung, gallbladder, cervical, colorectal, and head and neck tumors. We identify known cancer-associated pathogens consistent with the literature. In addition, we identify a significant prevalence of Fusobacterium in head and neck tumors, comparable to colorectal tumors. The Fusobacterium-high subgroup of head and neck tumors occurs mutually exclusive to human papillomavirus, and is characterized by overexpression of miRNAs associated with inflammation, elevated innate immune cell fraction and nodal metastases. We validate the association of Fusobacterium with the inflammatory markers IL1B, IL6 and IL8, miRNAs hsa-mir-451a, hsa-mir-675 and hsa-mir-486-1, and MMP10 in the tongue tumor samples. A higher burden of Fusobacterium is also associated with poor survival, nodal metastases and extracapsular spread in tongue tumors defining a distinct subgroup of head and neck cancer.
Audit of Electricity Generation in University of Lagos, Nigeria

Electricity is indispensable to a nation’s economic development. In this paper, analysis of energy sources was carried out to ascertain their costs. The selected energy alternatives are PHCN 132 kV/33 kV/11 kV Substation and Captive Cummings Diesel generator. The case study-site was University of Lagos, Akoka located within Lagos, a commercial city in Nigeria. Practical surveys and data collection were carried out from the power house coupled with their load estimation to obtain the total cost of electricity consumed. The results indicate that, on a monthly basis, the university spends about $820,000 on diesel generator and $228,500 on PHCN.The results also show that other alternative energy sources should be included in the overall energy mix in order to minimise the total power cost of the university.
Prevalence and determinants of death registration and certification uptake in Uganda

Death registration in Uganda remains extremely low, yet mortality statistics are vital in health policy, planning, resource allocation and decision-making. According to NIRA, only 1% of deaths are registered annually, while Uganda Bureau of Statistics estimates death registration at 24% for the period 2011–2016. The wide variation between the administrative and survey statistics can be attributed to the restriction to only certified death registration by NIRA while survey statistics relate to all forms of death notification and registration at the different sub-national levels. Registration of deaths is of critical importance to individuals and a country’s government. Legally, it grants administrative rights in management of a deceased’s estate, and access to social (insurance and pension) benefits of a deceased person. It is also essential for official statistics and planning purposes. There is an urgent need for continuous and real-time collection of mortality data or statistics in Uganda. These statistics are of significance in public health for identifying the magnitude and distribution of major disease problems, and are essential for the design, implementation, monitoring, and assessment of health programmes and policies. Lack of such continuous and timely data has negative consequences for the achievement of both national and Sustainable Development Goals 3, 11, 16, and 17. This study assessed the determinants of death registration and certification, using a survey of 2018–2019 deaths in 2,100 households across four administrative regions of Uganda and Kampala district. Multivariate–binary logistic regression was used to model factors associated with the likelihood of a death being registered or certified. We find that around one-third of deaths were registered while death certificates were obtained for less than 5% of the total deaths. Death registration and certification varied notably within Uganda. Uptake of death registration and certification was associated with knowledge on death registration, region, access to mass media, age of the deceased, place of death, occupation of the deceased, relationship to household head and request for death certificate. There is need for decentralization of death registration services; massive sensitization of communities and creating demand for death registration.
“I am my own doctor”: A qualitative study of the perspectives and decision-making process of Muslims with diabetes on Ramadan fasting

Background Many Muslims with diabetes choose to fast against medical advice during Ramadan, potentially increasing their risk of acute complications. Patients are often reluctant to disclose fasting to their health care providers, and their needs regarding Ramadan are not met in consultations. For healthcare professionals to provide patient-centred care, it is important to gain more insight into patients’ decision-making process. This study therefore aims to explore how Muslims with diabetes decide whether to fast during Ramadan. Methods A qualitative study was conducted consisting of 15 focus groups with Muslims with diabetes within a constructivist paradigm. Convenience sampling was used. All focus groups were transcribed verbatim and analyzed using Braun and Clarke’s reflexive thematic analysis. Results Four themes were found to be important in the decision on whether to fast: (1) values and beliefs concerning Ramadan, (2) experiences and emotions concerning Ramadan, (3) the perception of illness, and (4) advice from health care professionals, imams and family. Many participants indicated fasting against medical advice and trusting their subjective assessments on whether they could fast. Moreover, three main stages in the decision-making process for eventually refraining from fasting were identified: (1) the stage where positive experiences with fasting dominate, (2) the stage where one encounters challenges but their determination to fast prevails and (3) the stage where one decides to refrain from fasting after experiencing too many physical difficulties with fasting. Conclusions Muslims with diabetes experience autonomy in their decisions on Ramadan fasting. The decision to refrain from fasting often resulted from a difficult and dynamic decision-making process and was often made after participants reached their physical limits. These findings highlight the importance of not only shared decision-making to empower patients to make well-informed decisions on Ramadan fasting but also pre-Ramadan diabetes education to help people with diabetes have a safe Ramadan.
The magnitude of neonatal asphyxia and its associated factors among newborns in public hospitals of North Gondar Zone, Northwest Ethiopia: A cross-sectional study

Introduction Birth asphyxia is a prominent and avoidable cause of infant illness and death worldwide, particularly in underdeveloped countries such as Ethiopia. Early identification and control of the underlying contributory factors would help to alleviate the situation. As a result, the goal of this study was to assess the magnitude and determinants of neonatal asphyxia among live newborns at the northern Gondar public Hospitals in northwest Ethiopia. Materials and methods From April 1 to May 2, 2020, 357 newborns were studied in an institution-based cross-sectional study. The sample size was proportionally distributed among three public hospitals, namely Gondar referral teaching hospital, Debark general hospital, and Kola-Diba District Hospital, which was chosen at random. The number of deliveries given at each hospital six months prior to the data collecting period was used to allocate the hospitals. To get all participants, a systematic random sampling approach was adopted based on hospital delivery registration. The physicians’ evaluation of an APGAR score of 7 in the first and fifth minutes of birth was used as the confirmation of birth asphyxia. Data was collected using a standardized and pretested questionnaire. Variables having p-values less than 0.25 were entered into a multivariable logistic regression analysis in the bivariable analysis. At a p-value of 0.05, a statistically significant level was reported. Results As per the study, the total prevalence of neonatal asphyxia was found to be 27.1 (95% CI: 21.4, 32.7). In a multivariable logistic regression analysis, neonates born to rural mothers (AOR = 2.441, 95% CI: 1.137, 5.241), primiparity (AOR = 5.521 95%CI: 1.691, 8.026), premature rupture of membrane, (AOR = 3.202, 95% CI: 1.484, 6.909) and low birth weight (< 2.5kg) (AOR = 3.706, 95%CI: 3.307, 4.152) were all found to be independent predictors of birth asphyxia. Conclusion This study identified that rural residence, primiparity, premature rupture of membrane, and birth weight were found to be the independent predictors of birth asphyxia. The majority of variables that cause birth asphyxia can be controlled.
Mouse model and human patient data reveal critical roles for Pten and p53 in suppressing POLE mutant tumor development

Abstract Mutations in the exonuclease domain of POLE are associated with tumors harboring very high mutation burdens. The mechanisms linking this significant mutation accumulation and tumor development remain poorly understood. Pole+/P286R;Trp53+/– mice showed accelerated cancer mortality compared to Pole+/P286R;Trp53+/+ mice. Cells from Pole+/P286R mice showed increased p53 activation, and subsequent loss of p53 permitted rapid growth, implicating canonical p53 loss of heterozygosity in POLE mutant tumor growth. However, p53 status had no effect on tumor mutation burden or single base substitution signatures in POLE mutant tumors from mice or humans. Pten has important roles in maintaining genome stability. We find that PTEN mutations are highly enriched in human POLE mutant tumors, including many in POLE signature contexts. One such signature mutation, PTEN-F341V, was previously shown in a mouse model to specifically decrease nuclear Pten and lead to increased DNA damage. We found tumors in Pole+/P286R mice that spontaneously acquired PtenF341V mutations and were associated with significantly reduced nuclear Pten and elevated DNA damage. Re-analysis of human TCGA (The Cancer Genome Atlas) data showed that all PTEN-F341V mutations occurred in tumors with mutations in POLE. Taken together with recent published work, our results support the idea that development of POLE mutant tumors may involve disabling surveillance of nuclear DNA damage in addition to POLE-mediated hypermutagenesis.
Don’t you tweet me badly: Anxiety contagion between leaders and followers in computer-mediated communication during COVID-19

Do organizational leaders’ tweets influence their employees’ anxiety? And if so, have employees become more susceptible to their leader’s social media communications during the COVID-19 pandemic? Based on emotional contagion and using machine learning algorithms to track anxiety and personality traits of 197 leaders and 958 followers across 79 organizations over 316 days, we find that during the pandemic leaders’ tweets do influence follower state anxiety. In addition, followers of trait anxious leaders seem somewhat protected by sudden spikes in leader state anxiety, while followers of less trait anxious leaders are most affected by increased leader state anxiety. Multi-day lagged regressions showcase that this effect is stronger post-onset of the COVID-19 pandemic compared to the pre-pandemic crisis context.
High Low-Density Lipoprotein Cholesterol Levels are Associated with Osteoporosis Among Adults 20–59 Years of Age

Background Serum lipids are highly inheritable and play a major role in bone health. However, the relationship between low-density lipoprotein cholesterol (LDL-C) and bone mineral density (BMD) remains uncertain. The goal of this study was to see if there was a link between LDL-C levels and BMD in persons aged 20 to 59. Methods Using data from the National Health and Nutrition Examination Survey (NHANES) 2011–2018, multivariate logistic regression models were utilized to investigate the association between LDL-C and lumbar BMD. Fitted smoothing curves and generalized additive models were also used. Results The analysis included a total of 4909 adults. After controlling for various variables, we discovered that LDL-C was negatively linked with lumbar BMD. The favorable connection of LDL-C with lumbar BMD was maintained in subgroup analyses stratified by gender and race in both males and females, Whites and Mexican Americans, but not in Blacks and other races. The relationship between LDL-C and lumbar BMD in other races was an inverted U-shaped curve with the inflection point: 2.327 (mmol/L). Conclusion In people aged 20 to 59, our research discovered a negative relationship among LDL-C and lumbar BMD. Among races other than Whites, Blacks, Mexican Americans, this relationship followed an inverted U-shaped curve (inflection point: 2.327mmol/L). LDL-C measurement might be used as a responsive biomarker for detecting osteoporosis early and guiding therapy.
Analysis of the gut microbiota composition of myostatin mutant cattle prepared using CRISPR/Cas9

Myostatin (MSTN) negatively regulates muscle development and positively regulates metabolism through various pathways. Although MSTN function in cattle has been widely studied, the changes in the gut microbiota due to MSTN mutation, which contribute to host health by regulating its metabolism, remain unclear. Here, high-throughput sequencing of the 16S rRNA gene was conducted to analyze the gut microbiota of wild-type (WT) and MSTN mutant (MT) cattle. A total of 925 operational taxonomic units (OTUs) were obtained, which were classified into 11 phyla and 168 genera. Alpha diversity results showed no significant differences between MT and WT cattle. Beta diversity analyses suggested that the microbial composition of WT and MT cattle was different. Three dominant phyla and 21 dominant genera were identified. The most abundant bacterial genus had a significant relationship with the host metabolism. Moreover, various bacteria beneficial for health were found in the intestines of MT cattle. Analysis of the correlation between dominant gut bacteria and serum metabolic factors affected by MSTN mutation indicated that MSTN mutation affected the metabolism mainly by three metabolism-related bacteria, Ruminococcaceae_UCG-013, Clostridium_sensu_stricto_1, and Ruminococcaceae_UCG-010. This study provides further insight into MSTN mutation regulating the host metabolism by gut microbes and provides evidence for the safety of gene-edited animals.
Empirical investigation of ISO 9001 quality management systems' impact on organisational learning and process performances

This article studies the impact of ISO 9001 management systems on some dimensions of organisational learning and how this latter affects processes performance. Following the research of Mukherjee et al. (1998) which identifies the organisational learning constructs and shows their impact on project performance in the Total Quality Management (TQM) context, this article investigates the case for French companies. It is based on nine indepth interviews and on a quantitative study of 85 industrial processes of ISO 9001 certified companies. On the one hand, it evaluates the validity of the results of these authors. On this point, we find some significant differences, especially in terms of the impact of the factor scope. On the other hand, this study is broader than that of these authors in the sense that it contains a qualitative research on the impact of the ISO management system on knowledge creation and exchange.
Using Linguistic Ethnography to Study Video Consultations: A Call to Action and Future Research Agenda

Video consultations are a rapidly growing service model, particularly in secondary care. Studies, mainly using trials and post-hoc surveys, have routinely documented that they can be a safe and effective means to deliver care at a distance. While video offers new opportunities to provide health services, it also constrains how patients and clinicians can interact, raising questions about feasibility, quality, and safety—questions that cannot be adequately addressed with prevailing methods and approaches. To support successful and appropriate implementation, use and spread of video consultations, we need to investigate how video changes the interaction. In this article, we use two worked examples to demonstrate how Linguistic Ethnography, a methodological approach combining ethnographic with linguistic analysis, enables a detailed understanding of how communication in video consultations works, providing an evidence base to support patients and clinicians with using this service model.
Prevalence, Evolution, and Predictive Factors of Symptoms of Postpartum Posttraumatic Stress Disorder Iin a French-Speaking Cohort.

BACKGROUND Identifying factors that are predictive for postpartum posttraumatic stress disorder (PTSD) is important to inform clinical and research practice. Yet prospective longitudinal studies investigating symptoms of postpartum PTSD and their prevalence, evolution, comorbidities, and predictors remain limited. The aim of this study was to estimate the prevalence of women's symptoms of PTSD at different times in the postpartum period and to identify comorbidities and predictive factors in a French-speaking sample. METHODS A total of 168 women participated in this longitudinal study, which included 3 assessment points: immediate postpartum, 2 months postpartum, and 6 months postpartum. Participants filled out questionnaires regarding sociodemographic characteristics, pregnancy, and birth outcomes; subjective perceptions of birth; and symptoms of depression, anxiety, and PTSD. RESULTS Among the participants, 11.7% reported having symptoms of PTSD 2 months after birth and 10.5% reported having symptoms 6 months after birth. Regarding comorbidities and associated factors, depressive symptoms, poor marital adjustment, and impaired maternal-infant bonding were significantly and positively correlated with symptoms of PTSD. Peritraumatic distress, negative perceived childbirth experience, and complications and perceived difficulties during birth were predictive factors for postpartum PTSD. DISCUSSION More than 1 in 10 women experienced symptoms of postpartum PTSD. Health care professionals need to be aware of symptoms of postpartum PTSD, predictive factors, and comorbidities to be able to better identify women presenting those symptoms and refer them for appropriate psychological support.
