Published: January 2023

The crystal perfection of HgCdTe layers of heterostructures grown on (013)GaAs substrates with ZnTe and CdTe buffer layers and orientation rotation in the plane(angle φ) and perpendicular to the growth direction (angle theta) were studied by the method of second harmonic generation. A change in the angle φ for CdTe layers was observed depending on the GaAs substrate orientation and its non-monotonic change throughout thickness in the MCT layer of constant composition and graded widegap layers at its boundaries. An increase in the angle theta was observed when growing the upper graded widegap MCT layer. The absolute value of the angle theta can be used for a qualitative assessment of the crystalline perfection of the HgCdTe layers. Keywords: crystals of the sphalerite class, second harmonic, azimuthal angular dependencies, crystal perfection, CdxHg1-xTe heterostructures.

Heteroepitaxial Ge or Ge1-xSnx layers were grown by hot-wire chemical vapor deposition on Si(001) substrates doped heavily with a donor (As or Sb) impurity. The same layers were also grown on high-resistance Si(001) substrates for comparison. The depth profiles of carrier concentration were measured in both types of layers using the capacitance-voltage method, and carrier mobilities were measured additionally by the Hall effect method in layers on high-resistance silicon. It was found that the layers grown on high-resistance substrates were p-type, while the layers grown in the same regimes on heavily doped substrates were n-type with electron concentration n=(4-9)·1016 cm-3 in Ge layers and n=(2-4)·1017 cm-3 in GeSn layers. It was established experimentally and theoretically that the effect of autodoping of Ge and GeSn layers is lacking in the hot-wire chemical vapor deposition method. In our view, the growth of n-type Ge and GeSn layers on n+-Si(001) substrates doped heavily with a donor (As or Sb) impurity is associated with the segregation of this impurity in the process of growth of a buffer Si layer and its subsequent incorporation into growing Ge or GeSn layers. Keywords: epitaxy, doping, Ge, Si, Sn, concentration.

Recommendations From a Chinese-Language Survey of Knowledge and Prevention of Skin Cancer Among Chinese Populations Internationally: Cross-sectional Questionnaire Study
Authors: Chen Lily Ye , Niu Wei , Lim Kristina , Solomon James A
Published: January 2023

Background

There is a paucity of studies assessing awareness and prevention of skin cancer among Chinese populations.

Objective

The aim of the study is to compare attitudes and practices regarding skin cancer risks and prevention between Chinese Asian and North American Chinese populations and between Fitzpatrick scores.

Methods

A cross-sectional, internet-based, 74-question survey in Chinese was conducted focusing on Han Chinese participants internationally. The survey included Likert-type scales and multiple-choice questions. All participants were required to read Chinese and self-identify as being 18 years or older and Chinese by ethnicity, nationality, or descent. Participants were recruited on the internet over a 6-month period from July 2017 through January 2018 via advertisements in Chinese on popular social media platforms: WeChat, QQ, Weibo, Facebook, and Twitter.

Results

Of the 113 completed responses collected (participation rate of 65.7%), 95 (84.1%) were ethnically Han Chinese, of which 93 (96.9%) were born in China and 59 (62.1%) were female. The mean age of these 95 participants was 35.8 (SD 13.3) years; 72 (75.8%) participants were born after 1975. Few but more North American Chinese reported that Chinese Asian populations received annual skin checks (4/30, 4.2% vs 0/65, 0%; P=.009) and believed that their clinician provided adequate sun safety education (13/30, 43.3% vs 15/65, 23.1%; P=.04). Participants with higher Fitzpatrick scores less frequently received sun safety education from a clinician (4/34, 11.8% vs 22/61, 36.1%; P=.02). More participants with lower Fitzpatrick scores used sunscreen (41/61, 67.2% vs 16/34, 47.1%; P=.05), but alternative sun protection use rates are similar across groups.

Conclusions

Cultural differences and Fitzpatrick scores can affect knowledge and practices with respect to sun protection and skin cancer among social media–using Chinese Asian and North American Chinese communities based on respondent demographics. Most participants in all groups understood that people of color have some risk of skin cancer, but >30% of all groups across regions and Fitzpatrick scores are unaware of current skin protection recommendations, receive insufficient sun safety education, and do not use sunscreen. Outreach efforts may begin broadly with concerted public and private efforts to train and fund dermatologists to perform annual total body skin exams and provide more patient education. They should spark community interest through mass media and empower Chinese people to perform self-examinations and recognize risks and risk mitigation methods.
Effectiveness of Digital Mental Health Tools to Reduce Depressive and Anxiety Symptoms in Low- and Middle-Income Countries: Systematic Review and Meta-analysis
Authors: Kim Jiyeong , Aryee Lois M D , Bang Heejung , Prajogo Steffi , Choi Yong K , Hoch Jeffrey S , Prado Elizabeth L
Published: January 2023

Background

Depression and anxiety contribute to an estimated 74.6 million years of life with disability, and 80% of this burden occurs in low- and middle-income countries (LMICs), where there is a large gap in care.

Objective

We aimed to systematically synthesize available evidence and quantify the effectiveness of digital mental health interventions in reducing depression and anxiety in LMICs.

Methods

In this systematic review and meta-analysis, we searched PubMed, Embase, and Cochrane databases from the inception date to February 2022. We included randomized controlled trials conducted in LMICs that compared groups that received digital health interventions with controls (active control, treatment as usual, or no intervention) on depression or anxiety symptoms. Two reviewers independently extracted summary data reported in the papers and performed study quality assessments. The outcomes were postintervention measures of depression or anxiety symptoms (Hedges g). We calculated the pooled effect size weighted by inverse variance.

Results

Among 11,196 retrieved records, we included 80 studies in the meta-analysis (12,070 participants n=6052, 50.14% in the intervention group and n=6018, 49.85% in the control group) and 96 studies in the systematic review. The pooled effect sizes were −0.61 (95% CI −0.78 to −0.44; n=67 comparisons) for depression and −0.73 (95% CI −0.93 to −0.53; n=65 comparisons) for anxiety, indicating that digital health intervention groups had lower postintervention depression and anxiety symptoms compared with controls. Although heterogeneity was considerable (I2=0.94 for depression and 0.95 for anxiety), we found notable sources of variability between the studies, including intervention content, depression or anxiety symptom severity, control type, and age. Grading of Recommendations, Assessments, Development, and Evaluation showed that the evidence quality was overall high.

Conclusions

Digital mental health tools are moderately to highly effective in reducing depression and anxiety symptoms in LMICs. Thus, they could be effective options to close the gap in depression and anxiety care in LMICs, where the usual mental health care is minimal.

Published: January 2023

Background

The United Nations Sustainable Development Goals for 2030 include reducing premature mortality from noncommunicable diseases by one-third. Although previous modeling studies have predicted premature mortality from noncommunicable diseases, the predictions for cancer and its subcategories are less well understood in China.

Objective

The aim of this study was to project premature cancer mortality of 10 leading cancers in Hunan Province, China, based on various scenarios of risk factor control so as to establish the priority for future interventions.

Methods

We used data collected between 2009 and 2017 from the Hunan cancer registry annual report as empirical data for projections. The population-attributable fraction was used to disaggregate cancer deaths into parts attributable and unattributable to 10 risk factors: smoking, alcohol use, high BMI, diabetes, physical inactivity, low vegetable and fruit intake, high red meat intake, high salt intake, and high ambient fine particulate matter (PM2.5) levels. The unattributable deaths and the risk factors in the baseline scenario were projected using the proportional change model, assuming constant annual change rates through 2030. The comparative risk assessment theory was used in simulated scenarios to reflect how premature mortality would be affected if the targets for risk factor control were achieved by 2030.

Results

The cancer burden in Hunan significantly increased during 2009-2017. If current trends for each risk factor continued to 2030, the total premature deaths from cancers in 2030 would increase to 97,787 in Hunan Province, and the premature mortality (9.74%) would be 44.47% higher than that in 2013 (6.74%). In the combined scenario where all risk factor control targets were achieved, 14.41% of premature cancer mortality among those aged 30-70 years would be avoided compared with the business-as-usual scenario in 2030. Reductions in the prevalence of diabetes, high BMI, ambient PM2.5 levels, and insufficient fruit intake played relatively important roles in decreasing cancer premature mortality. However, the one-third reduction goal would not be achieved for most cancers except gastric cancer.

Conclusions

Existing targets on cancer-related risk factors may have important roles in cancer prevention and control. However, they are not sufficient to achieve the one-third reduction goal in premature cancer mortality in Hunan Province. More aggressive risk control targets should be adopted based on local conditions.
The Implementation of Federated Digital Identifiers in Health Care: Rapid Review (Preprint)
Authors: Ramamoorthi Karishini , Stamenova Vess , Liu Rebecca H , Bhattacharyya Onil
Published: January 2023

BACKGROUND

Federated digital identifiers (FDIs) have been cited to improve the interoperability of data and information management while enhancing the privacy of individuals verifying their identity on the web. Many countries around the world have implemented FDIs in various sectors, such as banking and government. Similarly, FDIs could improve the experience for those wanting to access their health care information; however, they have only been introduced in a few jurisdictions around the world, and their impact remains unclear.

OBJECTIVE

The main objective of this environmental scan was to describe how FDIs have been established and implemented to enable patients’ access to health care.

METHODS

We conducted this study in 2 stages, with the primary stage being a rapid review, which was supplemented by a targeted gray literature search. Specifically, the rapid review was conducted through a database search of MEDLINE and Embase, which generated a list of countries and their services that use FDIs in health care. This list was then used to conduct a targeted gray literature search using the Google search engine.

RESULTS

A total of 93 references from the database and targeted Google searches were included in this rapid review. FDIs were implemented in health care in 11 countries (Australia, Belgium, Canada, Denmark, Estonia, Finland, Iceland, Norway, Singapore, Sweden, and Taiwan) and exclusively used with a patient-accessible electronic health record system through a single sign-on interface. The most common FDIs were implemented nationally or provincially, and establishing them usually required individuals to visit a bank or government office in person. In contrast, some countries, such as Australia, allow individuals to verify their identities entirely on the web. We found that despite the potential of FDIs for use in health care to facilitate the amalgamation of health information from different data sources into one platform, the adoption of most health care services that use FDIs remained below 30%. The exception to this was Australia, which had an adoption rate of 90%, which could be correlated with the fact that it leveraged an opt-out consent model.

CONCLUSIONS

This rapid review highlights key features of FDIs across regions and elements associated with higher adoption of the patient-accessible electronic health record systems that use them, like opt-out registration. Although FDIs have been reported to facilitate the collation of data from multiple sources through a single sign-on interface, there is little information on their impact on care or patient experience. If FDIs are used to their fullest potential and implemented across sectors, adoption rates within health care may also improve.

Roles and Competencies of Doctors in Artificial Intelligence Implementation: Qualitative Analysis Through Physician Interviews (Preprint)
Authors: Tanaka Masashi , Matsumura Shinji , Bito Seiji
Published: January 2023

BACKGROUND

Artificial intelligence (AI) is a term used to describe the use of computers and technology to emulate human intelligence mechanisms. Although AI is known to affect health services, the impact of information provided by AI on the patient-physician relationship in actual practice is unclear.

OBJECTIVE

The purpose of this study is to investigate the effect of introducing AI functions into the medical field on the role of the physician or physician-patient relationship, as well as potential concerns in the AI era.

METHODS

We conducted focus group interviews in Tokyo’s suburbs with physicians recruited through snowball sampling. The interviews were conducted in accordance with the questions listed in the interview guide. A verbatim transcript recording of all interviews was qualitatively analyzed using content analysis by all authors. Similarly, extracted code was grouped into subcategories, categories, and then core categories. We continued interviewing, analyzing, and discussing until we reached data saturation. In addition, we shared the results with all interviewees and confirmed the content to ensure the credibility of the analysis results.

RESULTS

A total of 9 participants who belonged to various clinical departments in the 3 groups were interviewed. The same interviewers conducted the interview as the moderator each time. The average group interview time for the 3 groups was 102 minutes. Content saturation and theme development were achieved with the 3 groups. We identified three core categories: (1) functions expected to be replaced by AI, (2) functions still expected of human physicians, and (3) concerns about the medical field in the AI era. We also summarized the roles of physicians and patients, as well as the changes in the clinical environment in the age of AI. Some of the current functions of the physician were primarily replaced by AI functions, while others were inherited as the functions of the physician. In addition, “functions extended by AI” obtained by processing massive amounts of data will emerge, and a new role for physicians will be created to deal with them. Accordingly, the importance of physician functions, such as responsibility and commitment based on values, will increase, which will simultaneously increase the expectations of the patients that physicians will perform these functions.

CONCLUSIONS

We presented our findings on how the medical processes of physicians and patients will change as AI technology is fully implemented. Promoting interdisciplinary discussions on how to overcome the challenges is essential, referring to the discussions being conducted in other fields.
An End-to-End Framework for Extracting Observable Cues of Depression from Diary Recordings (Preprint)
Authors: Mlakar Izidor , Arioz Umut , Smrke Urška , Plohl Nejc , Šafran Valentino , Rojc Matej
Published: January 2023

BACKGROUND

Due to the prevalence of depression, its often chronic course, re-occurrences, and associated disability, early detection and non-intrusive monitoring present a crucial tool in timely diagnosing and treatment, remission of depression, prevention of relapse, and therefore limiting its impact on quality of life and well-being. Existing successful attempts in exploiting artificial intelligence for early classification of depression are mostly data-driven and thus non-transparent and lacking effective means to deal with uncertainties.

OBJECTIVE

We present an approach towards designing an explainable, knowledge-based artificial intelligence for classification of symptoms of depression. The aim of the study was to define and evaluate an end-to-end framework for extracting observable depression cues from diary recordings, and to evaluate the framework and explore the potential of the pipeline to present a feasible solution for detecting symptoms of depression automatically, using observable behavior cues.

METHODS

First, we defined an end-to-end framework for extracting depression cues (i.e., facial, speech, and language features), and stored them as a digital patient resource (i.e., the Fast Healthcare Interoperability Resource). Second, we extracted these cues from 28 video recordings from SymptomMedia dataset (14 simulating a variety of diagnoses of depression, and 14 simulating other mental health-related diagnoses), and 27 recordings from DAIC-WOZ dataset (12 classified as having moderate or severe symptoms of depression, and 15 without any depressive symptoms), and compared the presence of the extracted features between recordings of individuals with depressive disorder and those without.

RESULTS

We identified several cues consistent with previous studies in regard to their distinction between individuals with and without depressive disorders through both datasets among language (i.e., use of first-person singular pronouns, use of negatively valanced words, explicit mentions of treatment of depression, some features of language complexity), speech (i.e., speaking rate, voiced speech and pauses, low articulation rate, monotonous speech), and facial cues (i.e., rotational energy of heat movements. Other defined cues require further research.

CONCLUSIONS

The nature/context of the discourse, the impact of other disorders and physical/psychological stress as well as quality and resolution of recordings play an important role in alignment of digital features with relevant background. The work presented in this paper provides a novel approach for the extraction of wide array of cues, relevant for depression classification, and opens up new opportunities for further research.
Theory-Driven Statistics for the Digital Humanities: Presenting Pitfalls and a Practical Guide by the Example of the Reformation
Authors: Roller Ramona
Published: January 2023

The Digital Humanities face the problem of multiple hypothesis testing: Evermore hypotheses are tested until a desired pattern has been found. This practice is prone to mistaking random patterns for real ones. Instead, we should reduce the number of hypothesis tests to only test meaningful ones. We address this problem by using theory to generate hypotheses for statistical models. We illustrate our approach with the example of the European Reformation, where we test a theory on the role of opinion leaders for the adoption of Protestantism with a logistic regression model. Given our specific setting, including choice of data and operationalisation of variables, we do not find enough evidence to claim that opinion leaders contributed via personal visits and letters to the adoption of Protestantism. To falsify or to support a theory, it has to be tested in different settings. Our presented approach helps the Digital Humanities bridge the gap between the qualitative and quantitative camp, advance understanding of structures resulting from human activity, and increase scientific credibility.

EVROPSKA UNIJA KAO “ZAJEDNICA VREDNOSTI” U SVETLU RUSKO-UKRAJINSKOG SUKOBA
Authors: Radojicic Mirjana
Published: January 2023

U tekstu se razmatra odnos Evropske unije kao “zajednice vrednosti” prema tekućem ratu na prostorima Ukrajine. Oslanjajući se prvenstveno na metode kvalitativne analize i analize diskursa, autorka istražuje da li je i u kojoj meri EU u tom odnosu potvrdila svoju privrženost vrednostima koje afirmiše kao aksiološki sukus svog identiteta, u prvom redu vrednostima antifašizma i antinacizma, ozbiljno ugroženim dešavanjima u političkom životu Ukrajine od 2014. godine naovamo. U centralnom delu rada ona argumentuje u prilog svom stanovištu da se Unija, zajedno sa SAD kao prekookeanskim saveznikom u ovoj stvari, umesto zaštite ugroženih vrednosti sve vreme tekućeg rata rukovodila sopstvenim geopolitičkim interesom koji je definisala kao potpuni poraz Rusije u tom ratu. A njene kontinuirane isporuke oružja ukrajinskoj strani i mogući i sve izvesniji ruski nuklearni odgovor na te akte, prvi put nakon kubanske krize iz 60-ih godina prošlog veka doveli su svet na ivicu nuklearne katastrofe. Za EU, zaključuje autorka, antifašizam i antinacizam više ne postoje kao vrednosti, one više ne važe jer joj do njih – ukrajinski slučaj o tome nedvosmisleno svedoči – više nije stalo. Pitanje koje se po njenom mišljenju osnovano postavlja je: da li je ikada istinski i bilo?
ODJECI UKRAJINSKOG RATA NA BLISKOM ISTOKU
Authors: Jankovic Slobodan
Published: January 2023

U radu se analiziraju reagovanja bliskoistočnih zemalja na Ukrajinski rat i mogućnosti raspirivanja novih žarišta u regionu, u okviru globalnog rusko-zapadnog sukobljavanja, u kojem je Ukrajina najvidljivije bojište. Autor koristi italijansku neoklasičnu geopolitičku školu. On daje pregled odjeka po zemljama Bliskog istoka, od Libije do Irana i od Jemena do Turske. Konačno, autor zaključuje da je uopšteno, reagovanje zemalja regiona na rat u Ukrajini nezadovoljavajuće za Vašington i Brisel i dobro došlo u Moskvi. Nijedna zemlja u analiziranom području nije uvela sankcije Rusiji, pa čak i dugotrajni partneri SAD biraju neutralni status ili ekonomsku saradnju sa Rusiju. U pozadini američkog pristupa prema regionu je takođe konstantno rastući kineski ekonomski uticaj.

Знаменитый русский полководец генералиссимус Александр Суворов не проиграл ни одного сражения. Образ генералиссимуса очень популярен в России. В молодых государствах, которые появились после распада Советского Союза, образы исторических персонажей начали подвергаться коррекции. После государственного переворота на Украине в 2014 г. Александр Суворов стал восприниматься крайне негативно, потому что он олицетворял победу России. На Украине памятники Александру Суворову оказались под угрозой демонтажа. В Белоруссии крайне негативно к Александру Суворову относятся белорусские националисты, настроенные антироссийски. Для них Александр Суворов является врагом белорусского народа, потому что полководец подавил польское восстание Тадеуша Костюшко. Белорусские националисты воспринимают польское восстание белорусским.

Sexual communication between parents-adolescents during covid-19 pandemic in Malang
Authors: Maimunah Siti , Afiatin Tina , Febriani Arum
Published: January 2023

Implementing sexual communication between parents-adolescent is essential to protect adolescents’ sexual health. This research seeks to determine how parents-adolescents’ sexual communication was implemented during the COVID-19 pandemic. This research utilised a descriptive quantitative research method. One hundred sixty-seven parents participated in this study and were recruited through links that WhatsApp and Facebook shared. The parents must have adolescents between 11-19 years old and unmarried. The result revealed that the communication between parents and adolescents was more intense during the pandemic. Moreover, 16% of the time dedicated to it was increased. However, only a small number of parents (11.4%) recorded conducting sexual communication with their teenagers. 88% of respondents reported that the duration their teens spent online had increased, even though 55.6% of them implemented a limit on their internet time. The t-test independent sample result revealed communication differences assessed from gender (0.019) and age (0.025). However, there were no differences in education (0.081) and residential area (0.663). The expectation of this study’s outcome could be expected as a reference for the related government institutions and private organisations to enact an intervention program for parents about the importance of sexual communication for adolescents’ physical and mental health.

The current investigation stated that the antioxidant properties of Cissampelos pareira L. leaf extract of medicinal plants are a rich resource of ingredients that can be used in drug development for human life. The medicinal plant Cissampelos pareira with different solvents such as aqueous, acetone, ethanol, and methanol performed different concentrations like 100, 200, 300, 400, and 500μg/ml were carried out by three methods such as hydrogen peroxide scavenging (H2O2), DPPH and thiobarbituric acid assay. As per the antioxidant properties of C. pareira an aqueous extract of hydrogen peroxide scavenging (H2O2) showed the highest percentage of activity compared to the other methods of antioxidant. The minimum rate of antioxidant properties of DPPH in the C. pareira with 500 μg/ml in high activities than the low concentration. According to the acetone extracts of C. pareira leaf, the maximum percentage of inhibition in hydrogen peroxide scavenging (H2O2) whereas low percentages of inhibition by thiobarbituric acid activity at 500 μg/ml concentration, respectively. Although the extraction solvent ethanol reaction is a concern, the same trend of results of antioxidant properties of hydrogen peroxide scavenging (H2O2) assay showed excellent properties and minimum in thiobarbituric acid was found to be recorded with a maximum concentration of 500 μg/ml respectively. According to the methanolic extract of C. pareira leaf exhibited maximum antioxidant properties at 500μg/ml concentration and minimum percentage of activity at thiobarbituric acid, activity was found to be recorded respectively. Among the three methods, hydrogen peroxide scavenging (H2O2) showed excellent antioxidant activity compared with other methods and ascorbic acid as a standard. Antioxidant activities play a significant role in pharmacological functions because of bioactive ingredients. However, there are some health problems due to the deficiencies of macronutrients that establish an effective manner. This research article describes the current status of the world's herbal medicinal products and properties suggestions for facilitating C. pareira was better tomorrow in humanity.

Hydrodynamic modeling of rivers with flood simulation requires an accurate
description of the riverbed and inundation morphology. Depending on a
geodetic survey method and data collected, the digital elevation models with
different accuracy can be created. This paper describes the methodology for
creating a hybrid digital elevation model intended for hydraulic
calculations, analysis, and results systematization and interpretation. The
case study selected for illustration of the methodology is the flat ground
area surrounding the Tamis River in the Panonian Plain in Serbia. The
production steps, advantages and disadvantages of the created digital
elevation models with different surveying methods are explained, as well as
the application of the hybrid digital elevation model for the 1D- and 2D-
hydrodynamic modeling.

Dünyada ham petrolün azalması nedeniyle alternatif yakıt araştırmaları her geçen gün artmaktadır. Dizel motorlarda petrole alternatif yakıt kullanılmasının diğer bir amacıda çevreye daha az kirletici emisyon salmasıdır. Alternatif yakıtlarda dışarıya temiz emisyon salmasına karşın aynı zamanda motor veriminin de yüksek olması istenmektedir. Dizel motorlarında dizel yakıtına alternatif en iyi yakıt biyodizellerdir. Ayrıca motorlarda verim kaybının azaltılması segman-silinidir çifti arasındaki sürtünme ve aşınma miktarını azaltılması ile olmaktadır. Bu çalışmada; dizel motorlarda alternatif yakıt olarak yaygın kullanılan biyodizel yakıtının segman-silindir çifti arasındaki sürtünme ve aşınma davranışları dizel yakıtına göre karşılaştırılmıştır. Yapılan çalışma üç aşamadan oluşmaktadır. Çalışmanın birinci aşamasında Taguchi yöntemi kullanılarak sürtünme ve aşınma karakteristiklerinin optimum şartları verren deney parametreleri belirlenmiştir. İkinci aşamada, deneysel çalışma yapılarak dizel ve biyodizel yakıtının tribolojik özellikleri incelenmiştir. Çalışmanın son aşamasında ise segman-silindir çifti arasında oluşan aşınma mekanizması yapay sinir ağları (YSA) ile modellenmiştir. Yapılan çalışma ile; biyodizelin dizel yakıtına göre sürtünme katsayısının daha düşük olması ve bu nedenle aşınma miktarının daha düşük olduğu saptanmıştır. Aşınma miktarları karşılaştırıldığında optimum şartlar; biyodizel yakıtı, 150d/d ve 40 N yük altında elde edilmiştir. Deney sonuçlar YSA model ile tahmin edilmiştir. Bu sayede deney sayıları azaltılarak segman-silindir çifti arasındaki tribolojik özellikler incelenebilecektir.
Hvordan husker elever informationer i lineære tekster? En undersøgelse af elevers hukommelse for det læste ved læsning på iPad eller papir

Published: January 2023

Danmarks skoler digitaliseres samtidig med, at undersøgelser viser, at læsning af digitale tekster enten medfører ringere eller den samme læseforståelse, dog viser et nyt metastudie, at elevers læseforståelse generelt er dårligere ved læsning på skærm. I artiklen beskrives en undersøgelse af elevers læsning af tekster på hhv. iPad og papir (n = 239). Elever fra fem skoler inddeltes tilfældigt i to grupper og læste tre tekster med efterfølgende besvarelse af 35 spørgsmål med fokus på hukommelse for det læste. Forskellen i læsescore opgøres i forhold til læsning på papir (n = 117) eller iPad (n = 122) såvel som på køn (n (piger) = 128, n (drenge) = 104). Denne undersøgelse viser, at der ikke er nogen signifikant forskel mellem elevernes tekstlæsning på hhv. iPad og papir, dog med undtagelse af, at drenge læser signifikant bedre på iPad end på papir (p = 0,003, Cohens d = 0,307). Studiets resultater leder til overvejelser over, om drenge i højere grad skal tilbydes digitale tekster.
English abstract
English title: Students’ recall ability when reading linear texts on iPad or in print
In Denmark we see a rising digitalisation of schools and therefor also of reading on screen. Former studies has shown that reading on screen can lead to inferior reading comprehension, although some newer studies shows no difference. In this study students (N = 239) from five different schools were randomly divided into two groups to read three different texts on either iPad or in print and to fill out a multiple choice test with 35 questions focusing on lower level reading comprehension understood as the ability to recall information. The difference in reading score is found regarding reading on iPad (n = 122) or paper (n = 117) and gender (n (boys) = 104, n (girls) = 128). This study shows that there is no significant difference when it comes to reading comprehension understood as ability to recall text information. Taking gender into consideration, looking at boys performing on iPad or paper, the study shows a significant difference between the two reading medias. This study shows that boys perform better on iPad. The result should lead to considerations whether boys should be given reading tasks on iPad instead of in print.

The role of the community is one of the causes of the decline in the quality of drainage water. The decrease in the quality of drainage is related to behavior that is formed based on the characteristics of a person and their environment. The sample in this study is the community from 30 houses directly facing the drainage which is the object of research. The research aims to determine the effect of age, length of stay, and gender on people's behavior in managing household liquid waste and disposing of waste in trash cans. This research was analyzed quantitatively using SPSS, Paired Sample t-test for comparison test. The results of this study showed that the behavior of household wastewater management, age, length of stay, and gender did not have a significant effect. While the behavior of throwing garbage in the trash, only the age factor has a significant effect, while the length of stay and gender factors have no significant effect.
The Effect of Corporate Life Cycle on Corporate Restructuring
Authors: Sari Nur Afiqoh
Published: January 2023

This study aims to determine the effect of corporate life cycle on restructuring decisions with governance and financial distress as moderating variables in manufacturing companies listed on the Indonesia Stock Exchange in five years (2013-2017) and there are 480 data for the sample. The hypotheses tested using logistic regression. The results of this study indicate that life cycle has an effect on restructuring decisions. Financial distress strengthen the influence of the "birth" and "mature" stages to carry out managerial restructuring, and strengthen the "growth" stage to carry out operational restructuring and financial restructuring. However, financial distress does not moderate the influence of the life cycle on asset restructuring. Governance weakens the influence of the “birth” stage in managerial restructuring and also weakens the influence of the “birth” and “mature” stages in financial restructuring strategies. GCG does not moderate the effect of the life cycle on operational restructuring and asset restructuring.

Authors: Fasita Eta , Firmansyah Amrie , Irawan Ferry
Published: January 2023

This study investigates the association of transfer pricing aggressiveness, thin capitalization, and political connection with tax avoidance and the corporate governance's role in moderating these associations. The secondary data of this study are data and information obtained from financial reports and annual reports sourced from www.idx.co.id and www.idnfinancials.com. The analysis is conducted on 61 non-financial multinational companies listed on Indonesia Stock Exchange over the 2016-2019 period, chosen by the purposive sampling method resulting in 244 firm-year. Hypothesis testing employs regression analysis with a data panel.  The result suggests that transfer pricing aggressiveness and political connection are negatively associated with tax avoidance. In contrast, thin capitalization is positively associated with tax avoidance. However, corporate governance can weaken each of these associations. This study indicates that the Indonesian Tax Authority should consider multinational companies with large interest debt structures on the list of priorities in tax inspection policy. Also, this study shows Indonesian firms are less likely to use political connection and transfer pricing to avoid tax.

Background: University students are vulnerable to developing mental health problems due to constant exposure to academic demands. A situation that has been exacerbated by the COVID-19 pandemic and observed in several recent studies. Therefore, current practices require further research and identification of potentially protective factors for mental health. Objective: This study aimed to analyze academic self-efficacy as a protective factor against depression, anxiety, and stress in university students. Methods: A cross-sectional design was used with 3525 university students from Lima, Peru. The prevalence of depression, anxiety, and stress was measured using the DASS-21. Academic self-efficacy was measured with the EPAESA and defined as a predictor of the three mental health conditions. Structural equation modeling was used to test the model, together with a multigroup analysis for gender and working status. Results: One-third of the sample had severe to extremely severe symptoms of depression, anxiety, and stress. Academic self-efficacy was a moderately statistically significant predictor of the three mental health conditions. Relationships were invariant to gender and working status. Conclusions: Self-efficacy can be considered a protective factor for mental health. Interventions to promote academic self-efficacy may be effective in reducing depression, anxiety, and stress in university students. The findings are discussed together with current studies on the topic.
