Does The Presence Of Family Members Reduce Audit Quality?: Evidence From Family Firm In Indonesia
Authors: Muslim Ade Imam , Maghriby Bimbim , Ramdani Dani
Published: February 2025

Our research aims to investigate family presence on audit quality. We use a total of 1,960 observations from 182 family companies listed on the Indonesia Stock Exchange. The research method that we use is explanatory research through logistic regression. The results of the study provide empirical evidence that the presence of the family, especially the founder as president director and family members who sit on directors and commissioners, is indicated to reduce audit quality. Our research also provides indications of a stronger entrenchment effect in reducing audit quality in family firms in Indonesia. Family companies in Indonesia tend to pay lower audit fees and use local public accounting firms. Our research has broad implications for two things. The first is for investors in investing, especially to assess the audit quality of family companies. Investors are also expected to assess audit quality as one of the considerations in making an investment. Second, for family companies in improving corporate governance and credibility by involving KAPs from Big4.

Stability of Cephalosporins in Solution in Terms of the Colour of Solution and Impurities
Authors: Kuleshova S. I. , Denisova I. A. , Pshenichnykh T. I.
Published: February 2025

I

INTRODUCTION. Cephalosporins are injectable antibiotics, which are mainly free from excipients. Testing for impurities (degradation products) and the colour of solution can help evaluate degradation processes in cephalosporin active substances. Therefore, such testing is important for the quality control of cephalosporins.

AIM. This study aimed to evaluate the stability of cephalosporins in aqueous solutions in terms of impurities and the colour of solution and explore the relationship between these quality parameters.

MATERIALS AND METHODS. This study focused on cephalosporin active substances, including cefazolin, cefuroxime, ceftriaxone, and a combination of ceftriaxone and sulbactam (2:1). The colour intensity of aqueous solutions of these antibiotics was examined by visual comparison with reference standards and by spectrophotometry. The absorbance values of 10% cefazolin solution were measured at 430 nm at fixed intervals for 6 days, and those of 1.2% ceftriaxone and ceftriaxone–sulbactam solutions were determined at the maximum absorption wavelength of 450 nm for 11 days and 16 days, respectively. High-performance liquid chromatography (HPLC) was used to determine the content of related substances in solutions of cefazolin (10% and 0.25%), ceftriaxone (1.2% and 0.03%), and the ceftriaxone–sulbactam combination (1.2%, calculated as ceftriaxone). Ceftriaxone solutions were studied for 16 days, and cefuroxime solutions (10% and 0.1%) were studied for 2 days (48 hours). All the test solutions were stored at room temperature in natural light (away from direct sunlight).

RESULTS. During the test period, all the test solutions gradually acquired an intense yellow colour, and their absorbance and related substance content increased accordingly. Diluted solutions of cefazolin, ceftriaxone, and cefuroxime degraded significantly faster than the solutions of these antibiotics of a higher concentration. The experiment showed that the content of only one or two impurities increased during the first 24–96 hours of degradation, while the content of the remaining related substances changed insignificantly. Cefuroxime proved to be the least stable in aqueous solutions; the content of dezarbomoyl cefuroxime exceeded the limit specified by the regulatory requirements by 2.5 times after 24 hours of storage. The colour of 1.2% ceftriaxone deviated from the regulatory requirements after 24 hours, and the content of individual impurities exceeded the applicable limit for after 72 hours.

CONCLUSIONS. The study has shown that the stability of cephalosporins in aqueous solutions in terms of impurities and the colour of solution depends on the chemical structure of the substance, the concentration of the solution, and the duration of storage in natural light. A correlation has been demonstrated between the absorbance of cefazolin and ceftriaxone solutions and the content of individual impurities.
The influence of the timing of bud collection and meteorological factors on the effectiveness of introducing black currant accessions into in vitro culture
Authors: Dunaeva S. E. , Tikhonova O. A. , Malyshev L. L. , Gavrilenko T. A.
Published: February 2025

Background. The introducing of the accessions from the field collection into in vitro culture ensures their preservation under controlled environmental conditions. The literature sources offer contradictive information on the seasonal periods considered as the optimal ones for introducing samples of black currant Ribes nigrum L. into in vitro culture. This may be due to both the influence of abiotic factors and the genotypic characters of the accessions, as well as the characteristics of the explants and their cultivation conditions. In this regard, the purpose of this study was to analyze the influence of the period of buds’ isolation, and of the meteorological factors, such as temperature, precipitation, and humidity, on the results of introducing diverse black currant accessions from the field collection into in vitro culture. Materials and methods. The plant material included 30 black currant accessions from the VIR field collection. In different months of the summer periods of 2019-2022, buds were isolated from annual shoots to introduce them as explants into in vitro culture. All stages of introducing buds into in vitro culture were carried out in accordance with the Methodological Guidelines of VIR. Meteorological data were obtained from the VIR Department of Automated Information Systems for Plant Genetic Resources. The data were statistically processed using the “Statistica 10.0” package. Results. A strong contingency was found between the effectiveness of introducing explants into in vitro culture and the genotype, as well as the month and year in which the buds were selected. Meteorological factors influencing the results of introducing black currant explants into in vitro culture include temperature and air humidity on the day of bud collection and air humidity in the decade before taking explants. The duration of the period from the beginning of plants vegetation in the field collection to the date of bud sampling also had a significant impact on the result of introducing the explant into in vitro culture. Conclusion. In the case of bud selection in June, the proportion of infected explants is significantly lower, and the proportion of viable explants is higher, compared to buds taken in subsequent summer months. For the successful introducing of buds from a field collection into in vitro culture, the optimal weather conditions are low air humidity and relatively high temperature on the day of buds’ collection, as well as low air humidity in the decade before taking buds from plants of the field collection.

Published: February 2025

During excavations of historical monuments, archaeologists find various artifacts that testify to the existence and everyday life of our distant ancestors. Particular attention is paid to the remains of living organisms. They not only provide evidence of the economic activity of ancient farmers, but also help to identify phylogenetic relationships and domestication processes in the world's centers of diversity. Due to the long-term presence of paleontological objects in the environment that is not conducive to preservation, they often get destroyed and it becomes impossible to determine which species they belong to. Therefore, archaeologists increasingly resort to the help of paleogeneticists. The works on studies of ancient DNA (aDNA) from human and animal remains are known in Russia. However, paleogenetic studies of fossil plant remains such as pollen, seeds, and timber are few. In 2019, carbonized grains of cereal crops were found on the territory of the Usvyaty settlement in Pskov Region. The findings date back to the 12th century. The morphological analysis of the seed mixture resulted in finding grains, the degree of destruction of which prevented determination of the species they belong to by analyzing their microrelief. Therefore, the aim of this study was to develop taxon-specific primers that yield a short amplification product for the analysis of fragmented aDNA from the destroyed barley caryopses. As a result, a PCR test named HORDELF was developed, which is recommended for the identification of plant residues (carbonized seeds) belonging to the genus Hordeum L.

Stres adalah sesuatu yang dialami oleh semua orang, terutama mahasiswa fakultas kedokteran. Stres biasanya muncul dari masalah atau tugas yang belum terselesaikan, seperti pengerjaan skripsi bagi mahasiswa. Stres memiliki berbagai tingkat dan dipengaruhi oleh berbagai faktor. Penelitian ini bertujuan untuk mengevaluasi perbedaan tingkat stres antara mahasiswa yang sedang mengambil skripsi dengan mahasiswa yang tidak sedang mengambil skripsi di Fakultas Kedokteran Universitas Tarumanagara pada tahun 2024. Penelitian ini dilakukan dengan pendekatan kuantitatif dengan desain cross-sectional dan melibatkan 166 mahasiswa sebagai responden. Data penelitian diambil menggunakan metode random sampling serta dianalisis secara chi-square. Tingkat stres diukur menggunakan Perceived Stress Scale (PSS-10). Hasil penelitian menunjukkan bahwa terdapat perbedaan signifikan dalam tingkat stres antara kedua kelompok dengan p-value sebesar 0,048. Mahasiswa yang sedang mengambil skripsi cenderung memiliki tingkat stres yang lebih tinggi dibandingkan dengan mahasiswa yang tidak sedang mengambil skripsi. Data menunjukkan bahwa di antara mahasiswa yang sedang mengambil skripsi, 11 (18,96%) mengalami stres ringan, 42 (72,41%) mengalami stres sedang, dan 5 (8,62%) mengalami stres berat. Sementara itu, di antara mahasiswa yang tidak sedang mengambil skripsi, 39 (35,77%) mengalami stres ringan, 66 (60,55%) mengalami stres sedang, dan 4 (3,66%) mengalami stres berat. Temuan ini menyoroti adanya hubungan yang signifikan antara pengerjaan skripsi dan tingkat stres mahasiswa. Faktor-faktor seperti beban akademik, tenggat waktu, dan tekanan berkontribusi terhadap tingginya stres pada mahasiswa yang sedang mengambil skripsi. Disarankan agar fakultas memberikan edukasi manajemen stres dan kesehatan mental secara berkala serta melakukan evaluasi dan pemantauan rutin terhadap tingkat stres mahasiswa untuk meningkatkan kesadaran dan menyediakan intervensi yang sesuai.

Using the Information Metric to Analyze Clinical Rating Scales
Authors: Ramsay James O. , Li Juan , Bernstein Charles N. , Marrie Ruth Ann , Wallmark Joakim , Wiberg Marie
Published: February 2025

A rating scale is a set of categories designed to obtain information about a quantitative or a qualitative attribute. Item response theory (IRT) proposes that a probability function over a single latent variable represents the overall attribute evolution that the scale is designed to assess. Here we utilize an information theory approach to IRT to analyze rating scale data. The proposed IRT analyses, based on surprisal, offer new tools for assessing raters, rated items, and the whole rating scale. The information transformation from probability to surprisal is a new lens from which to view choice data and is an important augmentation of probability-based IRT. It also offers new graphical tools to measure the amount of information captured by an item in an additive metric, and to measure covariation among items using mutual information. The proposed methodology is illustrated using two scales from real clinical data and the proposed approach is compared with analyses made with the commonly used parametric IRT graded response model. Practical implications of the proposed methodology are provided.

تمارس السلطة التشريعية اختصاصاتها الواردة في الدستور الذي يعد صاحب سيادة في الدولة، وتكون بذلك تحت الرقابة المباشرة للقاضي الدستوري، كما أن المشرع قد يلجأ الى تسخير سلطته التشريعية لتحقيق أهداف شخصية أو فئوية أو حزبية لا علاقة لها بالمصلحة العامة, حيث ينحرف بذلك عن ممارسة وظيفته، ويتحقق الانحراف التشريعي بمخالفة القانون الصادر من قبل السلطة التشريعية لقواعد الاختصاص الدستوري أو الاجراءات التي رسمها الدستور للعملية التشريعية، أو المبادئ والأحكام العامة التي تهيمن على قواعد الدستور, أو بتجاوز غاياته لروح الدستور، وهنا يلزم القضاء الدستوري السلطة التشريعية بالسير في الحدود الدستورية التي رسمتها الوثيقة الدستورية, وتحقيق مبدأ الشرعية وحماية مبدأ سيادة القانون الذي يتوجب عدم خروج التشريعات على أحكام الدستور
الدبلوماسية الروسية إتجاه ثورة المستعمرات البريطانية في أمريكا الشمالية: (1763-1783)
Authors: م.د. بهجت شبيب فشاخ

برزت أهمية الدبلوماسية الروسية خلال حرب المستعمرات البريطانية في أمريكا الشمالية، بصورة كبيرة في واقع العلاقات الدولية، لا سيما مع محاولات أثبات الإمبراطورية الروسية قدرتها في الدفاع عن السلم الدولي، بعد فشل كل محاولات التدخل الدبلوماسي لدول القارة الاوروبية "الغرب" في مسألة أنهاء الحرب، إذ فضل الروس الخوض في غمار البحث عن حلول مقبولة عبر نافذة الحياد، بعد أنتظار تهيئة الظروف المناسبة لطرح مقترح تدعيم دبلوماسية الوساطة بين بريطانيا من جهة، وبين المستعمرات الأمريكية الثائرة وحلفائها من جهة أخرى، بعد اعلان تحالف فرنسا واسبانيا الدفاع عن المستعمرات الأمريكية، وبذلك أصبحت الساحة الدولية متاحة للتدخل الروسي، لكون الدول الثلاث الكبرى منشغلة بالحرب، الى جانب رفض وتعنت كلا الطرفين في قبول التسويات السياسية، لا بل ذهبا الى استمالة واشراك دول اخرى في الحرب ضناً منهم خيار الهزيمة او النصر هو الحل الأمثل. هيأة تلك الظروف الدولية الارضية الملائمة للتدخل الروسي بعد التراجع السياسي والاقتصادي الكبير في ميادين السياسة الدولية، وكانت الرؤية الروسية قد ركزت على تخليص المستعمرات من الاحتلال البريطاني عبر أساليب دبلوماسية، ولكن على أن لا يكون ذلك العمل الدبلوماسي بمثابة التدخل في الشؤون البريطانية، لذلك لابد من إيجاد طريقة لا تثير استعداء بريطانيا لروسيا.

“Stepping outside the red line": An exploration of two co-design methodologies exploring lived experiences of remote support for eating disorders throughout COVID-19 and beyond (Design4Health Conference, 2024)
Authors: Murphy-Morgan Claire Naomi , Branley-Bell Dawn
Published: February 2025

The COVID-19 pandemic necessitated the rapid transition to online support for eating disorders (Brothwood et al. 2021; Lewis et al. 2021). Beyond the context of the pandemic, remote support continues to be widely adopted and requested. The benefits of online support include its role as a virtual lifeline during the pandemic, its subsequent ability to provide a wider range of support methods, the convenience for recipients being able to access support at home and, for service providers, its cost-effectiveness and flexibility (Murphy-Morgan and Branley-Bell, 2022). Remote support also presents challenges in terms of accessibility, issues of digital self-efficacy and potentially problematic affordances of platforms. Examples include the potential anxiety of the recipient seeing their own self-image on camera during a video call, or a therapist's concern regarding individuals being able to hide behind the camera to mask the severity of their symptoms (Murphy-Morgan and Branley-Bell 2022: Waller et al. 2020). However, online services can provide an accessible form of support, including for individuals without diagnosis who are often left with no access to clinical services (Yim et al. 2021). Through interactive workshops, semi-structured interviews and a national survey, our research programme has gathered a range of perspectives about the challenges and opportunities presented by online support for eating disorders. Currently, there is little research exploring the diverse narratives of lived experiences of such support, what future interventions could be considered in improving provision, and how these decisions can be made. Co-design methodologies allow for a phenomenological approach in considering these questions, and the opportunity to redress potential power imbalances through allowing lived experience narratives to shape the interpretation and dissemination of research findings (Çarçani et al. 2023). It allows for a range of perspectives to be explored and is valuable in aiding identification of any overlooked aspects of new interventions (Marion and Cornish 2023). Creative approaches to co-design can provide new ways of understanding and articulating lived experiences (Vaart, Hoven, and Huigen 2018). In this paper, we explore, and reflect upon, two creative co-design approaches we have used: generating an animation portraying online support experiences, and a good practice toolkit for online support.
Social Comparison and Motivation
Authors: Diel Kathi , Crusius Jan , Hofmann Wilhelm , Friese Malte
Published: February 2025

Social comparison is a fundamental aspect of daily life with major implications for motivation and goal pursuit. By observing others, individuals can be inspired to set new goals and observe the steps needed to achieve them. Upward comparisons with more successful people typically drive self-improvement, while downward comparisons with less successful individuals may reduce motivation by providing a sense of reassurance and self-enhancement (i.e., coasting). This chapter delves into the varied motivational effects of social comparisons, examining both upward and downward comparisons, as well as the extremity of these comparisons. It also explores the emotional responses elicited by these comparisons and their subsequent influence on motivation. Further, the chapter examines the opposite direction of how different motivational states influence the selection of comparison targets and discusses how the different motivational impacts of upward and downward comparisons can be strategically applied in intervention studies to enhance motivation and goal attainment.
CHANGES IN SLEEP PATTERNS IN ADOLESCENTS IS MORE ASSOCIATED WITH PUBERTAL INDICATORS THAN AGE: A PERFECT STORM WITH A DASH OF HORMONES

Older adolescents tendo to stay awake longer in the evening and prefer to rise later but it is still unclear if these sleep changes occur as adolescents become older or more pubertally mature. This was investigated in a cross-sectional study with a community sample of 121 9-to-17-year-old Brazilian adolescents who informed on their circadian preferences (Morningness-Eveningness Scale for Children: MESC) and sleep habits [bed/rise times on weekdays and weekends, time in bed (TIB) and social jetlag]. We analyzed changes in these factors according to four development measured: age (in months), self-assessed pubertal status [Pubertal Development Scale (measures adrenal and gonadal changes) and Tanner pubertal staging by clinician (pubic hair and breast/genitalia development, respectively associated with adrenal and gonadal maturation), controlling for sex and socioeconomic status. Older age related only to later bedtimes on weekdays. Later bedtimes and less TIB on weekdays and weekends were more associated with Tanner ratings, particularly pubic hair maturation, whereas evening preference (MESC scores) was found in participants with higher PDS scores and genital/breast Tanner ratings. Adolescents’ age and pubertal maturation do not equally map onto sleep/circadian alterations. Adrenal maturation associates more with later bedtime and less TIB, while circadian phase-delay may be more gonadally-related.

The use of children's drawings to examining their conceptual understanding has been proven to be an effective method, but there are two major problems with previous research: 1. The content of the drawings heavily relies on the task, and the ecological validity of the conclusions is low; 2. The interpretation of drawings relies too much on the subjective feelings of the researchers. To address this issue, this study uses the Large Language Model (LLM) to identify 1420 children's scientific drawings (covering 9 scientific themes/concepts), and uses the word2vec algorithm to calculate their semantic similarity. The study explores whether there are consistent drawing representations for children on the same theme, and attempts to establish a norm for children's scientific drawings, providing a baseline reference for follow-up children's drawing research. The results show that the representation of most drawings has consistency, manifested as most semantic similarity>0.8. At the same time, it was found that the consistency of the representation is independent of the accuracy (of LLM’s recognition), indicating the existence of consistency bias. In the subsequent exploration of influencing factors, we used Kendall rank correlation coefficient to investigate the effects of "sample size", "abstract degree", and "focus points" on drawings, and used word frequency statistics to explore whether children represented abstract themes/concepts by reproducing what was taught in class. It was found that accuracy (of LLM’s recognition) is the most sensitive indicator, and data such as sample size and semantic similarity are related to it; The consistency between classroom experiments and teaching purpose is also an important factor, many students focus more on the experiments themselves rather than what they explain. In addition, most children tend to use examples they have seen in class to represent more abstract themes/concepts, indicating that they may need concrete examples to understand abstract things.
