Machine learning modeling for identifying predictors of unmet need for family planning among married/in-union women in Ethiopia: Evidence from performance monitoring and accountability (PMA) survey 2019 dataset
Authors: Kebede Shimels Derso , Mamo Daniel Niguse , Adem Jibril Bashir , Semagn Birhan Ewunu , Walle Agmasie Damtew
Published: October 2023

Unmet need for contraceptives is a public health issue globally that affects maternal and child health. Reducing unmet need reduces the risk of abortion or childbearing by preventing unintended pregnancy. The unmet need for family planning is a frequently used indicator for monitoring family planning programs. This study aimed to identify predictors of unmet need for family planning using advanced machine learning modeling on recent PMA 2019 survey data. The study was conducted using secondary data from PMA Ethiopia 2019 cross-sectional household and female survey which was carried out from September 2019 to December 2019. Eight machine learning classifiers were employed on a total weighted sample of 5819 women and evaluated using performance metrics to predict and identify important predictors of unmet need of family planning with Python 3.10 version software. Data preparation techniques such as removing outliers, handling missing values, handling unbalanced categories, feature engineering, and data splitting were applied to smooth the data for further analysis. Finally, Shapley Additive exPlanations (SHAP) analysis was used to identify the top predictors of unmet need and explain the contribution of the predictors on the model’s output. Random Forest was the best predictive model with a performance of 85% accuracy and 0.93 area under the curve on balanced training data through tenfold cross-validation. The SHAP analysis based on random forest model revealed that husband/partner disapproval to use family planning, number of household members, women education being primary, being from Amhara region, and previously delivered in health facility were the top important predictors of unmet need for family planning in Ethiopia. Findings from this study suggest various sociocultural and economic factors might be considered while implementing health policies intended to decrease unmet needs for family planning in Ethiopia. In particular, the husband’s/partner’s involvement in family planning sessions should be emphasized as it has a significant impact on women’s demand for contraceptives.

Published: October 2023

Due to the invasive nature of surgical procedures and the involvement of medical personnel, torture survivors may experience re-traumatization during surgical treatment. This study aimed to explore torture survivors’ experiences of re-traumatization during surgical treatment as well as the process by which trauma-related emotions and responses are evoked during surgical treatment for torture survivors. Eight men, aged 45 to 72, from four different countries, who have lived in Norway for 6–40 years, were recruited. We assessed torture and surgical care experiences through in-depth interviews, and the data were analyzed using thematic analysis, resulting in five themes: (1) Interactions with healthcare providers, (2) Reactions during treatment, (3) Triggers causing re-experiences, (4) Avoidance, and (5) Suggestions to healthcare providers. In this study, survivors reported challenges receiving surgical treatment, indicating re-traumatization and difficulty returning to daily life following treatment. Participants reported little collaboration in care-related decision-making processes, lack of recognition of torture by healthcare providers involved in surgical care and experiencing healthcare professionals’ attitudes as a source of perplexity, frustration, and despair. Exacerbation of torture memories throughout treatment and re-experiencing of trauma symptoms aggravated these difficulties. Our findings suggest that surgical treatment can remind torture survivors of the traumatic aspects of torture, eliciting strong reactions and feelings like those experienced during torture.
Gatekeepers in the health financing scheme: Assessment of knowledge, attitude, practices, and participation of Malaysian private general practitioners in the PeKa B40 scheme
Authors: Jamal Mohammad Husni , Abdul Aziz Aznida Firzah , Aizuddin Azimatun Noor , Aljunid Syed Mohamed
Published: October 2023

This is cross-sectional research done to assess the readiness of the private Malaysian general practitioners (GPs) for the implementation of the national health financing scheme. The study focused on their levels of knowledge and attitudes towards the types of health financing scheme, gatekeeper roles in the health financing scheme, and their participation in the PeKa B40 scheme. Their acceptance and level of participation in the national health financing scheme (NHFS) were also assessed. A set of self-designed and pre-tested questionnaires focusing on the aforementioned objectives were mailed to the respondents. The selection of respondents was done by stratified random sampling of the GPs in all 14 Malaysian states at both urban and rural levels. Out of a calculated number of 362 GPs targeted, 296 responses were received which represented a response rate of 81.7%. The respondents had a mean age of 50.7 years 165 (55.75%) were males and 131 (44.3%) were females. The rural respondents totalled 158 (53.4%) as compared to those from urban 138 (46.6%) areas. The outcomes observed were that GPs with PeKa B40 provider status, positive attitude towards health financing schemes, gatekeeper roles, and PeKa B40, were strongly associated with their acceptance and level of participation in the NHFS. The GPs possessed a positive attitude and were generally ready to participate in the NHFS, but the lower scores in knowledge levels would require definite education and training plans to further enhance their readiness. More incentives should be given to GPs to enrol as PeKa B40 providers. The results of this study should be strongly considered by the government in the efforts to engage the Malaysian private GPs in the forthcoming NHFS. Most importantly, the role of GPs as gatekeepers needed to be implemented, and the PeKa B40 scheme be greatly improved.
Manufacturer invasion and online sales mode strategy considering the level of service quality
Authors: Zhang Guanxiang , Liu Xinping , Su Guiping
Published: October 2023

This study investigates the decision process of own-brand intrusion by contract manufacturers and their selection of invasion sales modes under the consideration of service quality disparities between brand manufacturers and contract manufacturers. Specifically, the study constructs a three-tier supply chain system comprising a brand manufacturer, a contract manufacturer, and an e-commerce platform. The equilibrium profits under different sales mode combinations are determined by using reverse induction methodology, and the optimal sales mode combinations are analyzed and compared. The study reveals that the decision process of contract manufacturers’ own-brand invasion depends on the potential market demand. Furthermore, when brand manufacturers adopt the reselling mode, the service quality level does not affect the decision process of invasion sales modes. However, when brand manufacturers adopt the agency mode, contract manufacturers with low service quality levels are more suitable for invasion through the agency mode, whereas contract manufacturers with high service quality levels are better suited for invasion through the reselling mode. Additionally, for the equilibrium sales mode combination among members of the supply chain, it is observed that with lower commission rates, both brand manufacturers and contract manufacturers choose the agency mode, while with higher commission rates, both choose the reselling mode. When commission rates are moderate, brand manufacturers prefer the agency mode, whereas contract manufacturers prefer the reselling mode.
Changes in the prevalence of U.S. adults using diet, exercise, pharmaceuticals and diet products for weight loss over time: Analysis of NHANES 1999–2018
Authors: Kuk Jennifer L. , Daniels Simone B. , Ardern Chris I. , Pooni Rubin
Published: October 2023

To examine changes in the use of diet, exercise, and pharmacological/diet product weight loss (WL) practices over time, and differences in these trends by sex and obesity status, data from the National Health and Examination Survey (NHANES Continuous 1999–2018) was used. The prevalence of diet, exercise and use of WL drugs and products over time were examined in men and women with and without obesity in a series of cross-sectional nationally representative samples (n = 43,020). Women and those with obesity were more likely to engage in WL practices over the past year, with an increased prevalence of WL efforts over time (38.4 to 43.2%). Amongst those who engaged in WL attempts, diet-related WL was most common (87–93%), followed by exercise-related WL (47–68%), whereas use of WL drugs and products was the least common (5–21%). There were modest differences in the prevalence of diet or exercise WL over time, with some differences by sex and obesity status. Most notable was the increase in the prevalence of exercise WL practices in women with obesity, with no differences among men or women without obesity. When examining specific types of diets, there were more clear differences in the adoption of diets over time, with the use of more traditional calorie/portion/fat restriction diets becoming less prevalent, and sugar/carbohydrate restriction becoming more prevalent over time (P<0.005). Changes over time in the use of diets were, were however, similar in men and women with and without obesity. Use of pharmacotherapy/diet products tended to decline in prevalence over time but was consistently highest in women with obesity. Thus, there are differences in the types of WL strategies individuals have employed over time, with variations in their popularity of use by sex and obesity status. However, the pattern of changes over time were quite similar in men and women with and without obesity.
Predicting CRISPR-Cas12a guide efficiency for targeting using machine learning
Authors: O’Brien Aidan , Bauer Denis C. , Burgio Gaetan
Published: October 2023

Genome editing through the development of CRISPR (Clustered Regularly Interspaced Short Palindromic Repeat)–Cas technology has revolutionized many fields in biology. Beyond Cas9 nucleases, Cas12a (formerly Cpf1) has emerged as a promising alternative to Cas9 for editing AT-rich genomes. Despite the promises, guide RNA efficiency prediction through computational tools search still lacks accuracy. Through a computational meta-analysis, here we report that Cas12a target and off-target cleavage behavior are a factor of nucleotide bias combined with nucleotide mismatches relative to the protospacer adjacent motif (PAM) site. These features helped to train a Random Forest machine learning model to improve the accuracy by at least 15% over existing algorithms to predict guide RNA efficiency for the Cas12a enzyme. Despite the progresses, our report underscores the need for more representative datasets and further benchmarking to reliably and accurately predict guide RNA efficiency and off-target effects for Cas12a enzymes.

There is growing recognition that young people should be given opportunities to participate in the decisions that affect their lives, such as advisory groups, representative councils, advocacy or activism. Positive youth development theory and sociopolitical development theory propose pathways through which youth participation can influence mental health and wellbeing outcomes. However, there is limited empirical research synthesising the impact of participation on youth mental health and/or wellbeing, or the characteristics of activities that are associated with better or worse mental health and/or wellbeing outcomes. This scoping review seeks to address this gap by investigating the scope and nature of evidence detailing how youth participation initiatives can influence mental health and/or wellbeing outcomes for participants. To be eligible, literature must describe youth (aged 15–24) in participation activities and the impact of this engagement on participant mental health and/or wellbeing outcomes. A systematic scoping review of peer-reviewed and grey literature will be conducted using Scopus, PsycINFO, Embase, Medline and grey literature databases. The scoping review will apply established methodology by Arksey and O’Malley, Levac and colleagues and the Joanna Briggs Institute. Title, abstract, and full text screening will be completed by two reviewers, data will be extracted by one reviewer. Findings will be reported in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR), including a qualitative summary of the characteristics of youth participation and their influence on youth mental health outcomes. Youth advisory group members will be invited to deliver governance on the project from the outset; participate in, and contribute to, all stages of the review process; reflect on their own experiences of participation; and co-author the resulting publication. This scoping review will provide essential knowledge on how participation activities can be better designed to maximise beneficial psychosocial outcomes for involved youth.
Any Sound You Can Imagine: Then and now
Authors: Théberge Paul
Published: October 2023

During the 25 years since the publication of my book, Any Sound You Can Imagine: Making Music/Consuming Technology, a number of technological developments and theoretical trends have emerged: among them, the integration of music production within Digital Audio Workstation (DAW) platforms, and the rise of social media as a means for information sharing among musicians, on the one hand; and the emergence, in popular music studies, of practice-based and community-oriented forms of music research and pedagogy, on the other. In addition, new technologies and applications of artificial intelligence (AI) have begun to have an impact on music-making and listening at every level. These developments are discussed in relation to theoretical issues of innovation, production, consumption and gender found in my previous work and, more specifically, in relation to concerns raised in a number of articles in the present volume, using them as a springboard for further reflection and theorizing.

Although they are ordinary and almost everyone has them, genitals are riddled with controversies, taboos and anxieties. Despite their social and cultural importance, genitalia have been left out of systematic analysis and research in the context of social sciences and humanities. They are most often positioned in terms of dualisms that create, support and strengthen social distinctions, hierarchies and asymmetries. Transcending the essentialist gender ideas and binaries attributed to human bodies opens up space for new understandings of genitalia in movement, transformation and transition. The key question is: how do culture and media intersect/work through genital transformations? The papers featured here provide inspiring, innovative and research-stimulating responses to the complex presence and representation of genitalia through various media (online forums, novels, video art, performance art, television drama, reality television, mainstream news, feature film and vlogs). Each paper, as well as the entire thematic issue, represents a contribution to the further development of genital studies and strengthens the multidisciplinary questioning of genitalia, power, gender, differences, transgression and resistance.
Cult of the vulva vs. cult of the phallus: A case study of media presentations of some famous genitals
Authors: Holy Mirela , Borčić Nikolina
Published: October 2023

The society we live in is patriarchal, binary and hierarchically coded, evident from social and economic inequality and the stereotyping of men and women. Men are portrayed as active subjects and women as passive objects. Gender stereotyping extends to glorifying the male genitals as active, powerful, excellent and superior and objectifying the female genitals as passive, weak and corrupt. The social power of the media is essential in selecting information through agenda-setting and media framing. This article researches how the two most influential Croatian daily news portals, the progressive Jutarnji list and the conservative Večernji list, present female and male genitals in the media articles, mainly focusing on the genitals of celebrities. Famous people and celebrities are commodified into products created to influence the audience. The media presentation of their genitals can also affect the social perception of female and male sexuality. The research is based on a linguistic discourse analysis that includes language, context and interpretation on articles published in the digital extensions of Jutarnji list and Večernji list in the summer months of 2022 as units of analysis. The analytical matrix includes textual and visual ways of presenting the genitals of celebrities (attributes and connotations), their value and political orientation, and the valorization of sexuality along the axis of sex and gender. Research shows that digital extensions of Croatian daily newspapers (including the portal gloria.hr and sportski.jutarnji.hr), despite their different value orientations, are stereotypical and follow the accepted patriarchal binary dogma of male–female, positive–negative, active–passive, powerful–powerless, and that they depict male and female genitals with a visible cult-phallic media perspective.
Eurasia vol. 2: Mujer y agua
Authors: Doncel Abad David
Published: October 2023

El presente grupo de ensayos que el lector tiene en sus manos es una muestra del resultado de los trabajos presentados en las III Jornadas Internacionales coordinadas por el Grupo de Investigación Reconocido (GIR) «Humanismo Eurasia» de la Universidad de Salamanca, celebradas el 27-28 de mayo de 2021, en el Aula Magna de la Facultad de Filología. Este Grupo de Investigación se creó para ejercer una doble reivindicación en el ámbito de los estudios de Asia Oriental. Por un lado, es un ejercicio de resistencia desde el ámbito de las «viejas» humanidades frente al imperio tecnocrático de la novedad, impuesta por la incorporación de las ciencias humanas al modelo rentabilista e hiperproductivo de la sociedad del conocimiento, y amparada en la visión de «progreso» y «actualidad» de los ingenieros sociales de la Unión Europea. Por otro lado, este Grupo de Investigación debe entenderse como un lugar de reivindicación de un utopismo: Eurasia. Fruto de esta orientación en la iniciativa académica están siendo las Jornadas Internacionales de Investigación e intercambio que gestiona este GIR. La estructura de este volumen monográfico es fiel reflejo de las unidades de investigación que configuran el Grupo. Respecto al tema escogido, la cultura del agua y sus vinculaciones con el ámbito de la mujer, es reconocido como uno de los grandes tropos en el estudio tanto antropológico como literario, en todo el ámbito eurasiático. Se trata en todos los casos de apuntes de investigación, que invitan a una reflexión de largo recorrido que apunta hacia la configuración del gran proyecto de una Eurasia transcultural, solo posible en el ámbito del trabajo académico, como semilla de un renovado imaginario.

A felmérések azt mutatják, hogy a digitális érettségük elmarad a kkv szektor többi tagjától, a nagyvállaltokhoz képest pedig jelentősen. Tanulmányunkban egy Hajdú-Bihar megyei mikrovállalkozás digitalizációs fejlesztését mutatjuk be. A vállalkozóval készített interjú alapján megállapítottuk, hogy üzletmenetében az online, vagy IKT eszközök nem jellemzőek, nem is nagyon tudja mit és hogyan tudna alkalmazni. A folyamatainak feltárását követően egy személyre szabott applikációt fejlesztettünk, és néztük, hogyan hatott az eredményességére és hatékonyságára. Az eredmények azt mutatják, hogy egy kisebb beruházási költséggel is 30-50%-al növekedett mindkét mutatója a bevezetést követő 1-3 hónapban. Javasolt az eredményekre alapozva tevékenységét, az applikáció használatának sikerességét tovább figyelni és elemezni, ami alapot nyújthat a későbbi fejlesztéseknek.

At present, there are various traffic analysis approaches and tools accessible in all areas; nevertheless, there are not enough, or by all-means, resources, and supplies for the application of these tools, as these tools differ in their competencies, input supplies, and productivity. This paper aims to provide a new way for a cost-effective traffic analysis implementation, which does not require a lot of resources, combining two machine learning algorithms to count the vehicles, estimate their speed, and segment lanes from a video recording. The video recording can be done using a conventional mobile phone camera and can be processed using a simple hardware toolkit. To bear out the cost-effectiveness of the proposed procedure, we provide a cost comparison analysis with a radar-based mobile traffic counting device.

Nowadays businesses have become more aware about digitized value chains. Every business is trying their best to add values to their organizations. The adoption of digital technologies has changed organization in multiple ways at the same time. The food market is growing at global levels and various small businesses are coming up to promote and challenge their businesses to the big platforms and gaining benefit at enormous levels which automatically leads to the economic growth. But on the other hand, various Small and Medium sized Enterprises (SMEs) in food sector are facing problems to adopt digitization at every stage in terms of adding values to their firms due to various reasons. By adopting digitization in the value chains will not only results in the cost cutting, but also it will help the organizations to be more productive and efficient. In India, technology trends on daily basis and government is taking all possible steps to make the food industries fully digital, but still according to one of the surveys, it is observed that 53% of the corporates or businesses are far from their digital transformation goals. The main objective of this paper is to find out how the big firms of food industries are adding values to their organizations by accepting the digitization in their value chains. Also, this paper will identify different models and strategies used by famous organizations who are adding values in their organizations by adopting digitization at initial levels. Also, we will try to find out that what kind of budget friendly IoT devices are being operated by them which will also help the upcoming small enterprises in the near future.
Programa de liderazgo transformacional y su impacto en la cultura organizacional: caso Municipalidad Provincial de Huaura (Perú)
Authors: Coronado Espinoza Jesús Jacobo
Published: October 2023

Introduction/Objective: A transformational leader means originating and stimulating positive change in their followers. These leaders are not only involved and focused on the progress of each follower, but also on building a flexible organizational culture. The study sought to determine how the application of a transformational leadership program improves the organizational culture of the Provincial Municipality of Huaura, Peru. Methodology: Quantitative study, experimental design with pretest-posttest and control group, and explanatory scope. Data were collected through a pre- and post-test. The sample was random and included 60 workers of this entity, who were distributed in two groups of 30 elements each and were administered a 20-question questionnaire. Results: According to the Mann-Whitney U statistic, it was found that in the pretest the perception of organizational culture obtained a value of 0.216 higher than the theoretical Sig. (α = 0.05); however, after administering the program, in the posttest, the perception of the entity’s culture was 0.000 lower than the theoretical Sig. Conclusions: It was confirmed that the administration of a transformational leadership program significantly improved the organizational culture in the institution under study, since it contributed to the employees’ commitment to their work and the institution, to the sharing of new values and the assumption of better policies to face changing environments, as well as to innovate and accept risks, and to orient themselves as a team towards results.
New Biomarkers for Cardiovascular Disease

Published: October 2023

Cardiovascular disease is the leading cause of death and disability worldwide. Early detection and treatment of cardiovascular disease are crucial for patient survival and long-term health. Despite advances in cardiovascular disease biomarkers, the prevalence of cardiovascular disease continues to increase worldwide as the global population ages. To address this problem, novel biomarkers that are more sensitive and specific to cardiovascular diseases must be developed and incorporated into clinical practice. Exosomes are promising biomarkers for cardiovascular disease. These small vesicles are produced and released into body fluids by all cells and carry specific information that can be correlated with disease progression. This article reviews the advantages and limitations of existing biomarkers for cardiovascular disease, such as cardiac troponin and cytokines, and discusses recent evidence suggesting the promise of exosomes as cardiovascular disease biomarkers.
Retos de la psicología y la educación en contextos universitarios

Las Instituciones de Educación Superior tienen grandes retos como son la generación de conocimiento, formación de profesionales integrales, que sean competentes y con valores. Uno de los retos con el que nos encontramos es que el perfil del estudiante actual es diferente al de las generaciones anteriores. Son nativos digitales (han tenido un smartphone desde muy jóvenes) y están permanentemente conectados. El 90% de los adolescentes de los países tecnológicamente avanzados usa internet a diario, y buscan nuevos formatos de educación. Por ello, la universidad debe construir una experiencia de aprendizaje adecuada para los intereses y necesidades de ese perfil, porque la generación centennial, los nacidos a partir del 2000, va a representar el 75% de la fuerza laboral en los próximos años. El reto social es ineludible para las universidades, que no se podrán mantener al margen de esta transformación. De igual modo, el estudiante actual necesita nuevos formatos: Reducir la brecha con la sociedad (en conocimientos, competencias y aprendizaje). Y adaptarse a la nueva cultura digital.

El avance tecnológico impacta de forma determinante a la sociedad, en primer lugar, en lo que a sus modos de organización se refiere y, en consecuencia, en lo concerniente al despliegue de prácticas inscritas en diversos ámbitos ecológicos —en consideración del dispositivo conceptual de carácter ético y estético denominado ecosofía, propuesto por Felix Guattari (2005, p. 43), hacia la construcción sistemática de resistencia a los efectos del desarrollo interrelacionado, tanto de materias primas como de bienes de consumo a nivel global, algo característico del capitalismo tardío (Jameson, 1997)— y, de forma complementaria, en lo relativo a la capacidad de toma de decisiones, desde la consideración de los modos de organización y de las características de las prácticas en despliegue (Ascher, 2004; Castells, 2000; Hägerstrand, 1982).
Latin hypercubes for constrained design of experiments for data-driven models

Published: October 2023

The quality of data used for data-driven modeling affects the model performance significantly. Thus, design of experiments (DoE) is an important part during model development. The design space is constrained in many applications. In this work, the constrained case is investigated. An Latin hypercube based approach is applied and analyzed for strongly constrained design spaces. Contrary to commonly used optimization techniques, an incremental procedure is proposed. In every step, new data are added to the design. Each new point is selected by a distance-based criterion. The performance of the created designs is evaluated by the quality of the trained models. For different constraints, artificial data sets are created with a function generator. The performance of local model networks and Gaussian process regression models trained with those designs is evaluated and compared to models trained on data sets based on Sobol’ sequences.
Fast power tracking control of PV power plants for frequency support
Authors: Schulte Horst , Kusche Stephan
Published: October 2023

A power tracking controller for frequency support by photovoltaic power plants without battery storage is presented. Due to the decreasing inertia, regenerative systems such as wind turbines and photovoltaic power plants must provide an instantaneous reserve for fast frequency support in power systems. To provide grid support by PV power plants, a control scheme, and a design procedure are introduced to ensure power reserve by leaving the optimal operating point. A model-based generalized design procedure in the Takagi-Sugeno fuzzy framework for PV system with switched-mode DC-DC converter is presented to achieve the specified control objectives. Simulation studies show the applicability of the control scheme.
Hinzutreten, Verwandeltsein, Anderssein
Authors: Edinger Sebastian
Published: October 2023

Transformative theories of what distinguishes human beings from animals face the problem of conceptually managing the transition from animal to human. This paper will show that this transition contains logical problems that are more rhetorically glossed over than logically solved by the concept of second nature. In the first part, I develop two main concepts of transformative theories, namely that of Hinzutreten (additive capacities occurring in humans) and that of Verwandeltsein (humans already being of a different kind), before outlining in the second part Helmuth Plessner’s anthropological approach as one that elaborates not a transformation, but a holistic difference in the structure of human life as well as a non-metaphysical process of nature’s self-differentiation in human beings as opposed to animals.
