Published: December 2023

IntroductionPlant A/T-rich protein and zinc-binding protein (PLATZ) are plant-specific transcription factors playing a role in plant development and stress response. To assess the role of PLATZs in vascular system development and wood formation in poplar, a functional study for PtaPLATZ18, whose expression was associated with the xylem, was carried out. MethodsPoplar dominant repressor lines for PtaPLATZ18 were produced by overexpressing a PtaPLATZ18-SRDX fusion. The phenotype of three independent transgenic lines was evaluated at morphological, biochemical, and molecular levels and compared to the wild type.ResultsThe PtaPLATZ18-SRDX lines showed increased plant height resulting from higher internode length. Besides, a higher secondary xylem thickness was also evidenced in these dominant repression lines as compared to the wild type suggesting an activation of cambial activity. A higher amount of lignin was evidenced within wood tissue as compared to the wild type, indicating an alteration in cell wall composition within xylem cell types. This latter phenotype was linked to an increased expression of genes involved in lignin biosynthesis and polymerization. DiscussionThe phenotype observed in the PtaPLATZ18-SRDX lines argues that this transcription factor targets key regulators of plant growth and vascular tissues development.

IntroductionMany studies indicate a considerable impact of optimal pacing on long-distance running performance. Given that the amount of carbohydrates in metabolic processes increases supralinearly with the running intensity, we may observe differences between the pacing strategies of two long-distance races and different performance levels of runners. Accordingly, the present study aimed to examine the differences in pacing strategies between marathon and half-marathon races regarding the performance levels of runners.MethodsThe official results and split times from a total of 208,760 (marathon, N = 75,492; half-marathon, N = 133,268) finishers in the “Vienna City Marathon” between 2006 and 2018 were analyzed. The percentage of the average change of speed for each of the five segments (CS 1–5), as well as the absolute change of speed (ACS) were calculated. The CS 1–5 for the marathon are as follows: up to the 10th km, 10th – 20th km, 20th – 30th km, 30th – 40th km, and from the 40th km to the 42.195 km. For the half-marathon, the CS 1–5 are half of the marathon values. Four performance groups were created as quartiles of placement separately for sexes and races: high-level (HL), moderate to high-level (MHL), moderate to low-level (MLL), and low-level (LL).ResultsPositive pacing strategies (i.e., decrease of speed) were observed in all performance groups of both sex and race. Across CS 1–5, significant main effects (p &lt; 0.001) were observed for the segment, performance level, and their interaction in both sex and race groups. All LL groups demonstrated higher ACS (men 7.9 and 6.05%, as well as women 5.83 and 5.49%, in marathon and half-marathon, respectively), while the HL performance group showed significantly lower ACS (men 4.14 and 2.97%, as well as women 3.16 and 2.77%, in marathon and half-marathon, respectively). Significant main effects (p &lt; 0.001) for the race were observed but with a low effect size in women (ŋ2 = 0.001).DiscussionBetter runners showed more even pacing than slower runners. The half-marathoners showed more even pacing than the marathoners across all performance groups but with a trivial practical significance in women.

BackgroundSymptoms of anxiety and depression are prevalent among young adults and are a significant public health issue. College students are at a higher risk of experiencing poor mental health than other young people due to several factors, including moving away from home, financial pressures, heavy workload, poor time management skills, competitivity, new processes of socialization and insufficient coping mechanisms, among others. In addition, nursing students’ mental and physical health may also be affected by unhealthy lifestyle habits and health-related behaviors.AimTo determine the prevalence of symptoms of depression and anxiety, and the association between these symptoms and health-related behaviors, in a population of Spanish student nurses.MethodsCross-sectional study on a sample of 339 nursing students. We used the Hospital Anxiety and Depression Scale, the International Physical Activity Questionnaire-Short form, the Spanish Healthy Eating Index and an “ad hoc” questionnaire for sociodemographic variables. The association between psychological symptoms and health-related behaviors was analyzed through binary logistic regression models.ResultsThe prevalence of symptoms of depression and anxiety was 3.8% and 24.5%, respectively. Negative health-related behaviors were frequent, namely tobacco and alcohol consumption, suboptimal physical activity and diet. Moderate physical activity was associated with a lower probability of experiencing depressive symptoms. Symptoms of anxiety were related to a low level of physical activity, an unhealthy diet and alcohol consumption ≥2 times a week.ConclusionStudent nurses could benefit from the implementation of both physical and mental health promotion initiatives.

Objectives: With limited social security and health protection in Ghana, intergenerational support is needed by those living with NCDs, who incur recurrent costs when seeking NCD care. We measured the level of informal support received by NCD patients and identified factors that influence support provision.Methods: We surveyed 339 NCD patients from three hospitals in Ghana, who listed their social ties and answered questions about their relationship and support frequency. We analyzed the relationship between social support, demographic and health information, characteristics of social ties, and network characteristics.Results: Participants described 1,371 social ties. Nearly 60% of respondents reported difficulties in their usual work or household duties due to chronic illness, which was also the strongest predictor of support. Patients with higher wellbeing reported less social support, while older age and having co-habitant supporters were negatively associated with support, indicating caregiver burnout.Conclusion: Ghanaian NCD patients receive support from various caregivers who may not be able to handle the increasing healthcare and social needs of an aging population. Policies should therefore enhance resource pooling and inclusiveness for old age security.
Dreaming in the Digital Age
Authors: Krebs Victor J. 
Published: December 2023

This article explores one way of understanding how digital media are affecting our ability to distinguish reality from fantasy, by reading Bernard Stiegler’s diagnosis of our current cultural crisis, alongside Wilfred Bion’s dream theory. The central claim of the paper is that we can understand the technological pharmakon, its both poisonous and therapeutic nature, in terms of Bion’s definition of dreaming, as the commerce between consciousness and the unconscious negotiated by the “alpha function”. Understanding how the digital impacts our capacity to dream provides us with a tool to counteract its toxicity and to combat the thanatic impulse triggered by technological power.
From a binocular point of view – both from Stiegler’s perspective of our technical or “organological” evolution and from Bion’s perspective on the constitution of reality in dreaming – we can begin to see more clearly how to modulate our technological drive, in order to prevent the pharmakon from short-circuiting the very psychic function necessary to distinguish between reality and illusion. The paper ends with a discussion of the algorithmic effects on the living imagination in support of this contention.

Authors: Saudale Gillberth Cornelis Benjamin , Lerik Mariana Dinah Ch , Anakaka Dian Lestari 
Published: December 2023

Students have responsibilities as students of knowledge and complete academic tasks. The assignments given can help students to improve their understanding of the material presented. One of the problems that can be experienced by students related to academic assignments is that students often delay doing assignments in an academic context or what is known as academic procrastination. Academic procrastination is thought to be the result of a failure of self-regulation that adversely affects the well-being and academic performance of students. This problem was also found in students of the Psychology Study Program, Faculty of Public Health, Nusa Cendana University class 2017. One thing that can be done to overcome this problem is to provide Self-Regulated Learning training to students who often delay their academic assignments. This research was conducted to see the effect of Self-Regulated Learning training to reduce the level of academic procrastination behavior among students. This type of research is Quasi Experimental research. Participants in this study amounted to 13 students who have met the research requirements. The results of the analysis of research data indicate that Self-Regulated Learning training has an effect on reducing student academic procrastination behavior.

Abstract
In this study, we have separately evaluated the radiative and non-radiative recombination lifetimes for InGaN quantum well (QW) samples with different amounts of ion-implantation damage, and have investigated their temperature dependence. The radiative and non-radiative recombination lifetimes were calculated from photoluminescence (PL) decay time measured by time-resolved PL measurements, combined with the absolute internal quantum efficiency values estimated by the simultaneous photoacoustic and PL measurements. As a result, the experimentally observed radiative recombination lifetimes are almost the same for all samples, while the non-radiative recombination lifetimes are shorter for samples with larger ion-implantation damage. These findings will lead to a comprehensive understanding of carrier dynamics in InGaN-QW optical devices.

Published: December 2023

Abstract
Development (the dissolution of resist films in developer) is an important lithographic process. However, details of the dissolution of resist polymers remain unclarified. In this study, the viscosity of 2.38 wt% tetramethylammonium hydroxide (TMAH) aqueous solution with poly(4-hydroxystyrene) (PHS) was investigated using a quartz crystal microbalance method. The relationship between PHS concentration and the viscosity of 2.38 wt% TMAH aqueous solution with PHS was measured. The kinetics (temporal change) of viscosity and PHS concentration during development was clarified. The maximum PHS concentration achievable during development approximately corresponded to the TMAH concentration independently of the film thickness.

Published: December 2023

Abstract
Magnesium (Mg)-induced lateral crystallization (Mg-ILC) of amorphous germanium (Ge) on a SiO2 stacked structure was investigated. From Raman mapping images, the critical annealing temperature necessary to induce Mg-ILC of amorphous Ge was estimated to be about 350 °C. Furthermore, the Mg-ILC length was truly narrow (∼2 μm) compared with other metal catalysts after annealing at 350 °C for 1 h. To enhance the Mg-ILC, we have examined a two-step annealing method for Mg-ILC of amorphous Ge on SiO2. The Mg-ILC length is significantly enhanced (∼4.5 times) by using a two-step annealing process, which is due to the enhancement of Mg diffusion into amorphous Ge during first-stage low-temperature annealing.

المقاصد العامة في نظام الميراث
Authors: خليفه السنوسي ميلاد أ.سالمة 
Published: December 2023

تعد المقاصد الشريعة أحد أهم علوم الشريعة التي يحتاجها الناظر في أحكام الكتاب والسنة ,كما تعد أيضا من أكثر المطالب التي يحتاجها الفقيه قصد استنباط الأحكام من نصوصها.
وتتنوع المقاصد تنوعات كثيرة باعتبارات مختلفة فهي باعتبار تعلقها بعموم الأمة تنقسم إلى ثلاثة أنواع المقاصد العامة ,الخاصة والجزئية.
فالمقاصد العامة في الشريعة الإسلامية تلاحظ في جميع وأغلب أبواب الشريعة ومجالاتها ,فيدخل في هذا أوصاف الشريعة وغاياتها الكبرى, وهي التي تمت مراعاتها وثبتت إرادة تحقيقها على صعيد الشريعة كلها, فتدخل في مجال العبادات والمعاملات والعادات والعقوبات .
والناظر في نظام الميراث في الشريعة الإسلامية يجد أن الشارع قد راعى فيه الكثير من المقاصد العامة منها مقصد تحقيق مصالح الناس, الضرورية والحاجية والتحسينية, فالمقاصد الضرورية تتمثل في حفظ الدين والنفس والعقل والمال والنسل, حفظ الدين يتحقق في منع المرتد من الميراث ,وجعل إختلاف الدين مانع من موانع الميراث ,وحفظ النفس في حرمان القاتل من الميراث وحفظ النسل يتحقق في منع ميراث ولد الزنا وولد اللعان وتحريم الميراث بسبب التبني ,وحفظ العقل يتحقق في إخراج الخمر وجميع أنواع المسكرات من عناصر التركة , وحفظ المال اعتبر الإسلام المال ضرورة من ضروريات الحياة وشرع من التشريعات توجيهات ما يشجع على اكتسابه وتحصيله وطريقة انتقاله بعد الموت عن طريق الميراث الشرعي , ومن المقاصد الحاجية مثلا تجهيز الميت , ومن المقاصد التحسينية تجهيز الزوجة من تركة زوجها .
والتشريع الإسلامي ملئ بالأمثلة أيضا التي تدل على التدرج وعلى تحقيق العدل مثل العول والرد ومراعاة الفطرة السليمة, فأحكام الميراث جاءت متفقة مع الفطرة السليمة لذلك قدم في الميراث الابن على ابن الابن , وابن الابن على ابن ابن الابن وهكذا . ومقصد التيسير والتخفيف على الناس يتحقق في التخارج .
إذا نجد أن نظام الميراث في الإسلام نظام محكم كل شيء فيه محدد تحديدا دقيقا وثابتا.
