In the learning process, teachers must be able to create an effective and fun learning atmosphere, so that students are able to concentrate on understanding learning. One of the things that teachers can do in improving student concentration is to apply the picture and picture method. This learning strategy has advantages, such as the teacher can better know the abilities of each student, students are trained to think logically and systematically, students are assisted to learn to think from the point of view of the subject matter, students' motivation to learn is increasingly developed, and students are involved in class planning and management. However, this strategy also has drawbacks, such as requiring a lot of time, some students become passive, there is concern that there will be chaos in class, there are certain students who do not like to work with others, and the need for adequate facilities, tools, and costs. This article describes the stages in implementing the picture and picture method. From the results of the study it can be concluded that the picture and picture learning model can be used as a way to increase student concentration in learning.

Published: April 2024

Objective: We aimed to evaluate bidirectional genetic relationships between posttraumatic stress disorder (PTSD) and COVID-19. Methods: We investigated potential causal associations between PTSD and two COVID-19 conditions (COVID-19 hospitalization and SARS-CoV-2 infection) via Mendelian randomization (MR) analyses. Three genome-wide association study (GWAS) summary datasets were used in the study, including PTSD (N = 174,659), SARS-CoV-2 infection (N = 2,597,856), and COVID-19 hospitalization (N = 2,095,324). We performed a literature-based analysis to uncover molecular pathways connecting PTSD and COVID-19. Results: We found that PTSD exerts a causal effect on SARS-CoV-2 infection (odds ratio (OR): 1.10, 95% confidence interval (CI): 1.00–1.21, p = 0.048) and hospitalized COVID-19 (OR: 1.34, 95% CI: 1.07–1.67, p = 0.001). However, both SARS-CoV-2 infection and hospitalized COVID-19 were not associated with the risk of PTSD. Pathway analysis revealed that several immunity-related genes may link PTSD to COVID-19. Conclusions: Our study suggests that PTSD was associated with increased risks for COVID-19 susceptibility and severity. Early diagnosis and effective treatment of PTSD in individuals infected with the coronavirus may improve the management of the outcomes of COVID-19.
Pre-Excited Atrial Fibrillation in Wolff-Parkinson-White (WPW) Syndrome: A Case Report and a Review of the Literature
Authors: Schiavone Marco , Filtz Annalisa , Gasperetti Alessio , Zhang Xiaodong , Forleo Giovanni B. , Santangeli Pasquale , Biase Luigi Di
Published: April 2024

Wolff-Parkinson-White (WPW) syndrome is defined by specific electrocardiogram (ECG) changes resulting in ventricular pre-excitation (the so-called WPW pattern), related to the presence of an accessory pathway (AP), combined with recurrent tachyarrhythmias. WPW syndrome is characterized by different supraventricular tachyarrhythmias (SVT), including atrioventricular re-entry tachycardia (AVRT) and atrial fibrillation (AF) with rapid ventricular response, with AVRT being the most common arrhythmia associated with WPW, and AF occurring in up to 50% of patients with WPW. Several mechanisms might be responsible for AF development in the WPW syndrome, and a proper electrocardiographic interpretation is of pivotal importance since misdiagnosing pre-excited AF could lead to the administration of incorrect treatment, potentially inducing ventricular fibrillation (VF). Great awareness of pre-excited AF’s common ECG characteristics as well as associated causes and its treatment is needed to increase diagnostic performance and improve patients’ outcomes. In the present review, starting from a paradigmatic case, we discuss the characteristics of pre-excited AF in the emergency department and its management, focusing on the most common ECG abnormalities, pharmacological and invasive treatment of this rhythm disorder.

Published: April 2024

The optimal management of heart valve disease (HVD) is still debated and many studies are underway to identify the best time to refer patients for the most appropriate treatment strategy (either conservative, surgical or transcatheter interventions). Exercise pulmonary hypertension (PH) can be detected during exercise stress echocardiography (ESE) and has been demonstrated to have an important prognostic role in HVD, by predicting symptoms and mortality. This review article aims to provide an overview on the prognostic role of exercise PH in valvulopathies, and its possible role in the diagnostic-therapeutic algorithm for the management of HVD.

Published: April 2024

Background: Women are frequently underrepresented in clinical trials and databases focusing on ventricular arrhythmias (VAs). However, understanding sex-based differences in risk factors and the prognosis of VAs is essential for tailoring personalized prevention and treatment strategies. This study aimed to investigate sex differences in the epidemiology, risk factors, and prognosis of VAs in patients with sepsis. Methods: We conducted a comprehensive analysis of 27,139 sepsis patients (mean [SD] age, 66.6 [16.2] years; 15,626 [57.6%] male), among whom 1136 (4.2%) developed VAs during their hospitalization. We evaluated VAs incidence and potential risk elements in both male and female patients, along with in-hospital mortality. Results: Men had a significantly higher likelihood of developing VAs compared to women (odds ratio [OR]: 1.70, 95% confidence interval [CI]: 1.50–1.94, p < 0.001). In the case of non-ischemic cardiomyopathy (NICM), the association with VAs was stronger in men than in women (relative risk ratio [RRR] = 1.63, 95% CI: 1.10–2.40, interaction p = 0.014). Furthermore, we observed significant sex-specific interactions in the relationship between incident VAs, congestive heart failure (CHF) (RRR = 1.35, 95% CI: 1.03–1.76, interaction p = 0.031), and pneumonia (RRR = 1.33, 95% CI: 1.02–1.74, interaction p = 0.036) when considering the adjusted model. The presence of VAs was associated with a nearly twofold increase in the risk of in-hospital mortality, a result that was observed in both sexes. Conclusions: In sepsis patients, the emergence of VAs independently escalates the risk of in-hospital mortality, with a notable correlation between male sex and an increased VAs risk. The impacts of CHF, NICM and pneumonia on incident VAs were significantly influenced by sex.
ScholarOne - Why Institutions Matter for M&A
Authors: wang hui
Published: April 2024

Why and how do M&A overall destroy value? This study of two mergers and
acquisitions (M&A) cases generates propositions exploring that
question. The human capital entering the merged firm was shaped in
congruence with pre-M&A institutional constraints (e.g., rules,
incentives) and is institution specific. The human capital value is
dependent on, not independent of, pre-M&A institutions. However, the
combining of two firms likely alters the firm institutions and gives
rise to the incongruence of institutions and the human capital. This
incongruence precipitates the devaluation of the human capital, which
causes post-M&A production loss. This study improves the firm-specific
human capital theory by connecting institutions as the key attribute of
a firm to human capital and thus explains human capital devaluation in
M&A, in which workers mostly do not change firm. This study also
highlights the practical importance of assessing a target’s
institutional fit pre-transaction and avoiding unnecessary institutional
changes post-transaction.
ScholarOne - The effectiveness of integrating e-commerce and logistics management in higher education programmes
Authors: Zhang Baohua
Published: April 2024

With global e-commerce’s rapid growth, cross-border e-commerce has begun
driving international trade. To meet the demand for skilled
professionals, higher education institutions have integrated
cross-border e-commerce and logistics management courses into their
curricula. However, scholars and educators still debate this
integration’s effectiveness. This systematic literature review
summarizes the literature on the effectiveness of the new curricular
integration, finding that it enhances students’ learning, improves
employability, increases engagement, broadens international perspective,
and improves courses’ industry relevance. However, the new curriculum
faces a lack of a standardized curriculum and faculty expertise, limited
resources, a rapidly changing landscape, and evaluation and assessment
challenges.
Nano scattering particle: an approach to improve quality of the commercial led
Authors: Anh Nguyen Doan Quoc
Published: April 2024

The light-emitting diodes (LEDs) have emerged as a sustainable illumination solution in the lighting industry. However, the commercial LEDs suffer from low chromatic rendition performance. This work proposes a feasible approach to enhance the quality of commercial LED packages via regulating scattering factors. The TiO2 nano scattering particles are added into the YAG:Ce3+ compound to enhance the internal scattering performance, inducing the blue-light conversion and extraction. In this work, TiO2 concentration varies from 0 wt% to 20 wt%. Results show that 5 wt% of TiO2 is the right concentration to achieve the optimal scattering performance for improvements in luminosity and color rendition of the LED. If the TiO2 concentration is beyond 5 wt%, these two parameters decline owing to too intensive light scattering. Meanwhile, 10 wt% is the most appropriate concentration of TiO2 to enhance the color uniformity of the LED.

Power-law behavior and inequality in the upper tail of wealth, income and consumption: evidence from India
Authors: Kumar Rishabh
Published: April 2024

This paper analyzes the upper tails of wealth, income, and consumption in India over the period 2012-18 using rich- lists, wealth surveys, income tax returns and consumer expenditure surveys. We find the upper tail to obey a power- law in all three economic resources. Comparing our estimates in 2012 – where we possess data on wealth, income, and consumption simultaneously – we find that the upper tail of wealth is most concentrated, income slightly less, and consumption is much less concentrated. Unlike wealth and income, the Pareto coefficients for consumption are estimated to have a well-defined mean and variance.

Previous studies have widely demonstrated that inhibition of return (IOR) with audiovisual targets decreases due to audiovisual integration (AVI). It is currently unclear, however, whether the impaired AVI in children with attention-deﬁcit/hyperactivity disorder (ADHD) has effects on IOR. The present study used the cue-target paradigm to explore differences between the IOR of audiovisual targets and the IOR of visual targets in ADHD and typically developing (TD) children. The results showed that, there was a smaller magnitude of IOR with audiovisual targets as compared with visual targets in the two groups. Importantly, the reduction of IOR in audiovisual conditions was significantly smaller in children with ADHD than in children with TD. Race model analyses further confirmed that differences in IOR between ADHD and TD are due to deficits of audiovisual integration in ADHD. The results indicated that children with ADHD have impaired audiovisual integration, which has a minimal impact on IOR.
Navigating Mental Health in the New Social Media Age: The Effects of Consuming Online Mental Health Information on Adolescents Well-being
Authors: Tian Weiqi , de Looper Melanie
Published: April 2024

The growing influence of new social media platforms centered around Online Short Videos (OSVs) in everyday life has raised important questions about its effects of usage durations on well-being of young adults. This transition towards new social media provides an abundance of information, including mental health-related content, whose effects on well-being are not yet fully understood. The current study was prompted by the urgent needs to understand these effects, including a focus on examining whether young adults’ varying levels of anxiety and depression would moderate these relationships. Following a person-specific approach, a sample of N=64 participants was included in a three-week experience sampling method (ESM) study to examine their new social media usage, OSVs consumption, exposure to anxiety/depression-related content, as well as their momentary well-being. Contrary to expectations, the study did not yield statistically significant results. These results underline the complexity of the relationship between new social media use, OSV consumption, anxiety/depression-related content exposure, and well-being, highlighting the need for further comprehensive research in this field.

Observational learning allows us to learn to make decisions by observing the behaviors of others. The quality of such learning depends not only on the ability of the observed other, the demonstrator, but also on our beliefs about their abilities. We have previously demonstrated that observers learned to avoid an aversive outcome better from demonstrators described as high in ability, regardless of the demonstrator’s actual performance. Building on these findings, our study aimed to replicate these findings, and to investigate the neural mechanisms underlying description-sensitive observational learning. Forty-five participants engaged in an observational aversive learning task while undergoing functional magnetic resonance imaging. We manipulated the descriptions of the abilities of the demonstrators, while keeping their actual abilities low. We hypothesized that participants would perform better when demonstrators were described as having a high vs. low ability. We further investigated if brain activity in regions associated with observational learning, social impression formation and mentalizing were sensitive to the demonstrator’s described ability. Contrary to expectations, participants performed equally well regardless of the description of demonstrator ability. Subsequent analyses revealed however, that described ability influenced the level of copying, such that participants copied the choices of the demonstrators more when these were described as having high rather than low ability. Our findings point to the involvement of mentalizing processes combined with more general learning and decision-making processes in driving the behavioral effects of biased observational learning.
On the Dearth of Retractions in Social Work: A Preliminary Analysis of Ten Leading Journals
Authors: Dunleavy Daniel J.
Published: April 2024

Both qualitative and quantitative-oriented journals play a key role in the cultivation and dissemination of social work knowledge. Editors and peer reviewers support this role –ostensibly – by serving as a form of quality control. Though the published literature is in some ways validated by prepublication peer review, errors, omissions, and even cases of outright fraud are inevitably published, contaminating the professional literature. Publishers and journal editors have a series of tools at their disposal to respond, such as errata, corrigenda, and expressions of concern. In extreme cases (e.g., fraud, research misconduct, plagiarism), a paper may be retracted and removed from the published record altogether. When appraising journals or publishers, the presence of retractions is not necessarily problematic – in moderation, this may indicate a robust ability to self-correct. However, when retractions are scarce or altogether absent, it may signify suboptimal mechanisms for self-correction within both journals and the broader scientific community. The preliminary analysis presented here suggests this latter scenario is likely the case for the discipline of social work – where retractions are effectively absent at ten leading journals. This is curious, given the notable increases in retractions across the biomedical and social sciences over the past few decades. Reasons for this absence are explored and recommendations to enhance the integrity of social work research and journals are discussed. Particular emphasis is placed on tools editors and peer reviewers can employ now.
Unbiased Confidence Intervals in Psychological Testing: The Regression-Based True Score Approach With Scale Correction
Authors: Schmukle Stefan C.
Published: April 2024

Two different approaches for calculating confidence intervals (CIs) for individual scores in psychological testing practice have been discussed in the literature within the framework of classical test theory, but unfortunately, both approaches can lead to biased estimates. The traditional approach (CI: observed score ± z · standard error of measurement) fails to take into account the phenomenon that, with imperfect measurement, true scores will be closer to the population average than observed scores will be (regression to the mean). On the other hand, the regression approach (CI: regression-based true score estimate ± z · standard error of the estimate) takes regression to the mean into account. However, this approach leads to confidence intervals that are on a different scale than the observed scores. The different scaling occurs because true scores have a smaller standard deviation than observed scores, and the extent of this shrinkage depends on the reliability of the test. It is thus incorrect, for example, to interpret true scores as falling on a standard scale (like T-scores) even when the observed scores were measured on such a scale. Here, I suggest a scale correction for the regression-based true score estimate to preserve the scaling, and thus to ensure both the accuracy and interpretability of the confidence intervals. Simulations indicate that this approach has the desired properties and outperforms the two existing approaches. The regression approach with scale correction is therefore recommended for calculating confidence intervals for individual scores in psychological testing practice.
Durably reducing conspiracy beliefs through dialogues with AI

Conspiracy theories are a paradigmatic example of beliefs that, once adopted, are extremely difficult to dispel. Influential psychological theories propose that conspiracy beliefs are uniquely resistant to counterevidence because they satisfy important needs and motivations. Here, we raise the possibility that previous attempts to correct conspiracy beliefs have been unsuccessful merely because they failed to deliver counterevidence that was sufficiently compelling and tailored to each believer’s specific conspiracy theory (which vary dramatically from believer to believer). To evaluate this possibility, we leverage recent developments in generative artificial intelligence (AI) to deliver well-argued, person-specific debunks to a total of N = 2,190 conspiracy theory believers. Participants in our experiments provided detailed, open-ended explanations of a conspiracy theory they believed, and then engaged in a 3 round dialogue with a frontier generative AI model (GPT-4 Turbo) which was instructed to reduce each participant’s belief in their conspiracy theory (or discuss a banal topic in a control condition). Across two experiments, we find robust evidence that the debunking conversation with the AI reduced belief in conspiracy theories by roughly 20%. This effect did not decay over 2 months time, was consistently observed across a wide range of different conspiracy theories, and occurred even for participants whose conspiracy beliefs were deeply entrenched and of great importance to their identities. Furthermore, although the dialogues were focused on a single conspiracy theory, the intervention spilled over to reduce beliefs in unrelated conspiracies, indicating a general decrease in conspiratorial worldview, as well as increasing intentions to challenge others who espouse their chosen conspiracy. These findings highlight that even many people who strongly believe in seemingly fact-resistant conspiratorial beliefs can change their minds in the face of sufficient evidence.

Male infertility constitutes a public health problem today in developing countries. But populations are faced with very high costs and difficult access to specialized centers in order to benefit from quality care. These obstacles lead couples in distress to turn to medicinal plants to treat possible causes of infertility. The aims of this study is to evaluated effects of Flueggea virosa and Heliotropium indicum, two plants from northern Ivory Coast on spermatogenesis in Wistar rats male. Aqueous and hydro-ethanolic extracts of the two plants leaves were first analysed through phytochemical screening by the staining and precipitation methods. Then effects of their two aqueous extracts were evaluated on spermatogenesis in Wistar rats. Each extract was administrated at concentration of 100 mg/kg body weight orally to test Wistar rats. A reference standard fertilizer product, Fertilo Forte Denk (FFD) was used at 5 mg/kg body weight as positive control to treat Wistar rats. After 30 and 60 days of treatment, mobility, viability, density and morphology of rat’s spermatozoa were evaluated by observation under an optical microscope. Phytochemical screening revealed the presence of polyphenols, flavonoids, gallic tannins, catechic tannins, alkaloids and saponosides in all the aqueous and hydroethanolic extracts of F. virosa and H. indicum. For spermatogenesis effects in Wistar rats, the study highlights that aqueous extracts from leaves of F. virosa and H. indicum induce an increase in the number, an improvement of the mobility and viability of spermatozoa after 60 days of treatment. But this increase is more significant (P < 0.001) in rats treated with F. virosa compared to control and group treated with FFD. According to these results, aqueous extracts from F. virosa and H. indicum leaves improve quality of sperm in rats. These data might justify the use of these two plants in treatment of certain cases of male infertility.
