Background
Integration of mobile health data collection methods into cohort studies enables the collection of intensive longitudinal information, which gives deeper insights into individuals’ health and lifestyle behavioral patterns over time, as compared to traditional cohort methods with less frequent data collection. These findings can then fill the gaps that remain in understanding how various lifestyle behaviors interact as students graduate from university and seek employment (student-to-work life transition), where the inability to adapt quickly to a changing environment greatly affects the mental well-being of young adults.

Objective
This paper aims to provide an overview of the study methodology and baseline characteristics of participants in Health@NUS, a longitudinal study leveraging mobile health to examine the trajectories of health behaviors, physical health, and well-being, and their diverse determinants, for young adults during the student-to-work life transition.

Methods
University students were recruited between August 2020 and June 2022 in Singapore. Participants would complete biometric assessments and questionnaires at 3 time points (baseline, 12-, and 24-month follow-up visits) and use a Fitbit smartwatch and smartphone app to continuously collect physical activity, sedentary behavior, sleep, and dietary data over the 2 years. Additionally, up to 12 two-week-long bursts of app-based ecological momentary surveys capturing lifestyle behaviors and well-being would be sent out among the 3 time points.

Results
Interested participants (n=1556) were screened for eligibility, and 776 participants were enrolled in the study between August 2020 and June 2022. Participants were mostly female (441/776, 56.8%), of Chinese ethnicity (741/776, 92%), undergraduate students (759/776, 97.8%), and had a mean BMI of 21.9 (SD 3.3) kg/m2, and a mean age of 22.7 (SD 1.7) years. A substantial proportion were overweight (202/776, 26.1%) or obese (42/776, 5.4%), had indicated poor mental well-being (World Health Organization-5 Well-Being Index ≤50; 291/776, 37.7%), or were at higher risk for psychological distress (Kessler Psychological Distress Scale ≥13; 109/776, 14.1%).

Conclusions
The findings from this study will provide detailed insights into the determinants and trajectories of health behaviors, health, and well-being during the student-to-work life transition experienced by young adults.

Exploración sobre el grado de cumplimiento de los derechos de los médicos residentes en México
Authors: Castro Roberto , Sarmiento-Chavero Mauricio , Romay-Hidalgo Frida , Castañeda-Prado Andrés 
Published: April 2024

Introducción: A pesar de la legislación que garantiza los derechos de los médicos residentes, existen prácticas que van en contra de esta normativa. Se ha documentado el maltrato y la violencia sufrida por los médicos residentes, pero hay pocos estudios desde la perspectiva jurídica.
Objetivo: Determinar el grado de cumplimiento de los derechos de los médicos residentes según la normativa vigente en México.
Método: Se aplicó una encuesta en línea a médicos residentes sobre diferentes áreas temáticas relacionadas con el entorno académico y laboral, experiencias de violencia y conocimiento y ejercicio de sus derechos tales como conocimiento de su programa de formación, asistencia médica, apoyos para la atención y otros. Construimos un índice de cumplimiento de derechos basado en siete dimensiones.
Resultados: Contestaron la encuesta 678 médicos residentes. Se observan deficiencias en el cumplimiento de los derechos de quienes cursan la residencia. Se identificaron problemas en el conocimiento del programa, asistencia médica, apoyo para la atención de pacientes, violencia por parte de pares o superiores, supervisión y observancia de derechos básicos. El índice de cumplimiento de derechos mostró que el 33.7% de los residentes tenía un índice de cumplimiento de derechos de .5 o menor.
Discusión: Los resultados son consistentes con lo que se reporta en diversos estudios que documentan diversas formas de maltrato y abuso que experimentan los residentes.
Conclusiones: Se requiere tomar medidas para combatir la violencia y asegurar el cumplimiento de los derechos establecidos. La principal limitación de esta investigación es el carácter no aleatorio de la muestra. Sin embargo, los resultados muestran la necesidad de ampliar la investigación.

Published: April 2024

Introducción: Las actividades de simulación clínica a menudo se acompañan de un material instruccional de apoyo que se entrega previamente. Este, paradójicamente, puede implicar aumento de la demanda de recursos mentales para poder procesarlos. La teoría de la carga mental propone una capacidad limitada de la memoria de trabajo, por tanto, se hace necesaria la medición de la carga mental asociada con el material instruccional.
Objetivo: Evaluar la carga mental en simulaciones de baja fidelidad en estudiantes de enfermería, con y sin el uso de material instruccional interactivo.
Método: Estudio cuantitativo, experimental, diseño de caso y control. La muestra fue de 105 estudiantes, de tipo censal, con asignación aleatoria al grupo control y caso. El grupo caso fue expuesto a material instruccional tipo video y lectura de guía de aprendizaje, versus el grupo control, expuesto solo a lectura. Se midió la carga mental con instrumento NASA-TXL, después de una simulación de baja fidelidad.
Resultados: Las medias de puntaje para los grupos control y caso, fueron, respectivamente: demanda mental 5.69 ± 1.93 vs 6.24 ± 2.17 (p > 0.05), demanda física 3.22 ± 1.91 vs 3.47 ± 2.13 (p > 0.05), demanda temporal 4.89 ± 2.32 vs 5.49 ± 2.71 (p >0.05), esfuerzo 6.98 ± 1.78 vs 7.61 ± 1.83 (p < 0.05), nivel de frustración 4.81 ± 2.50 vs 6.02 ± 2.83 (p < 0.05) y rendimiento 7.91 ± 1.49 vs 7.71 ± 1,45 (p > 0.05)
Conclusiones: Existieron diferencias significativas en las escalas esfuerzo y nivel de frustración. En las escalas demanda mental, física y temporal, el grupo caso presenta mayores puntajes, sin diferencias significativas. El rendimiento auto percibido fue menor en el grupo caso.
New food plants for insects Vilbasteana oculata (Hemiptera: Cicadellidae) and Otiorhynchus smreczynskii (Coleoptera: Curculionidae) in the Baltic region
Authors: Stalažs Arturs 
Published: April 2024

Vilbasteana oculata (hemipteran) and Otiorhynchus smreczynskii (beetle) are alien species in countries around the Baltic Sea, and they are continuing to spread. Sometimes when entering new areas where other plant species are found, herbivores tend to add to their range of food plants. Knowledge of the feeding trends of particular insect species can be useful in predicting possible changes in insect-plant trophic relationships in other regions where they expanding in range. This study looks at the feeding trends of two insect species – V. oculata and O. smreczynskii. The study was carried out mainly in Latvia, as well as in other expeditions in Estonia, Lithuania, Poland and Sweden. In this study, four Fraxinus and four Ligustrum species were confirmed as the new food plants for V. oculata. The main food plants for adults of O. smreczynskii probably originally belonged to the genera Ligustrum and Syringa. In this study, a number of alternative food plants have been recorded for the first time, generally woody and some herbaceous plants. Most of the newly registered food plants for O. smreczynskii belong to the families Oleaceae and Rosaceae. Other food plants belong to the families Adoxaceae, Celastraceae, Elaeagnaceae, Ericaceae, Grossulariaceae, and Rhamnaceae. V. oculata was confirmed in Poland (2017) and Sweden (2019) for the first time.

Published: April 2024

The aim of the present study was to compare morphological and physiological responses to increasing salinity of the two subspecies of Mertensia maritima during in vitro propagation in two different systems, and subsequent ex vitro cultivation. Plants were brought into culture using seeds and further propagated on Murashige and Skoog medium supplemented with thidiazuron and naphthaleneacetic acid either on agar-solidified or liquid medium with a temporary immersion system (Plantform bioreactors). Salinity tolerance were tested both in tissue culture and with ex vitro greenhouse-cultivated plants. Low concentration of NaCl increased explant biomass in agar-solidified medium, with no negative consequences even at high concentration. However, the effect of salinity on liquid medium was genotype-specific. Explants in Plantform bioreactors showed several-fold higher biomass in comparison to that on agar-solidified medium, but the multiplication potential was not significantly affected. Ex vitro plants were negatively influenced by increasing NaCl concentration in substrate. In contrast to in vitro plants, accumulation potential of Na⁺ in ex vitro plants was low. One of adaptations to salinity at the whole plant level was maintenance of adequate tissue mineral nutrient homeostasis, as mineral nutrient concentrations were not negatively affected by increasing salinity.

AI and assessment in higher education
Authors: Deneen Christopher 
Published: April 2024

Generative artificial intelligence (genAI) has shown immense potential for revolutionising education. Revolutions are disruptive, however. They carry potential for both positive change and high-stakes failure. In higher education, the implications of the genAI revolution for educational assessment are high profile and high stakes. Assessment is the primary mechanism for determining students’ outcome achievement. Quality of assessment and the resulting data determines the legitimacy of progressing students through their formal study and conferral of degrees. Will genAI enhance or impede these essential educational functions?
This Trendsetter talk will address this question through exploring dynamic tensions around the relationship of genAI to assessment in higher education. The speaker will address the possibilities genAI presents for repositioning students in critical, authentic ways relative to assessment. We will also explore potential advantages posed by genAI for teachers, such as enhancing efficiency in feedback and marking. Conversely, we will identify and discuss how to offset the very real problems posed by genAI to academic integrity, ethical practice, and validity of assessment results. The talk will conclude with suggestions on pathways we may take to increase the likelihood of this as a successful revolution and minimise high-staked failures.

Authors: Giyanti Giyanti , Oktaviyanthi Rina 
Published: April 2024

Abstract:Mathematical decision-making abilities are mathematical information processing through risk evaluation and investigation of various possibilities and perspectives. However, the evaluation of mathematical decision-making abilities is still limited to high, medium, and a low level based on test scores and is not predictive naturally. The purpose of this study is to identify the parameter k in the k-nearest neighbor technique, which serves as the nearest-neighbor value determining the mathematical decision-making abilities of students to be predicted. The process of data exploration to prediction is employed by the data mining approach with the k-Nearest Neighbor method. A total of 65 first-year students taking Calculus I included as research samples. The research results show that a parameter value of k=15 is better at predicting the closeness of the mathematical decision-making with an accuracy of 93.33%, associated with the excellent category. The parameter value representing the closeness of the decision-making abilities level among students serves as a reference for teacher predictions to categorize students and create diversified teaching materials.Abstrak:Kemampuan pengambilan keputusan matematis merupakan pemrosesan informasi secara matematis melalui evaluasi risiko dan penyelidikan berbagai kemungkinan dan sudut pandang.

The “autumn effect” in the gold market—does it contradict the Adaptive Market Hypothesis?
Authors: Potrykus Marcin , Augustynowicz Urszula 
Published: April 2024

Abstract
The present study aims to verify the autumn effect in the gold market, first presented 10 years ago by Dirk Baur in the paper “The autumn effect of gold” and to investigate the calendar effects occurring for other precious metals. This empirical research is presented in a way to place the results obtained in the context of the Efficient Market Hypothesis (EMH) and the more current Adaptive Market Hypothesis (AMH). The study was conducted as an extended reproduction of the Baur study. The main conclusion is that, the autumn effect on the gold market has been reversed and replaced by the winter effect, which is linked to the AMH. An equally interesting calendar effect was observed for silver. Platinum and palladium saw an increase in prices in January, but given the patterns in the gold market, it is very likely that this phenomenon will also change over time.
