Background: Nigeria is one of the hyper-endemic countries for hepatitis B with national prevalence rate of 11%. No study has been done in Nigeria to the best of authors’ knowledge to assess the level of immunity among children vaccinated against HBV. Objective: To assess prevalence of Hepatitis B surface antigen, determine the presence of antibodies to hepatitis B surface antigen (anti-HBs) and determine the titre levels of anti-HBs among those who have anti-HBs. Design: This was a pilot and a cross-sectional study. Methods: Consecutive children aged between 2 and 17 years seen at the outpatient clinic of NAUTH, Nnewi, Nigeria were recruited. Questionnaire was interviewer-administered. Venous blood was collected from each participant, analyzed for HBV serological markers and anti-HBs titre. Results: A total of sixty children were recruited. There was equal male and female distribution. 36.7% were aged 10-14 years. One child did not receive HBV vaccine. There was no incidental finding of HbsAg positivity. 15% of respondents had their immunity assessed after completing vaccination. There was presence of antibodies to HBsAg in19 children, and the anti-HBs titre was protective in 78.9% of those who had antibodies. Conclusion: After 18 years of introduction of the HBV vaccine into the NPI and routine infant immunization against hepatitis B virus in Nigeria, this pilot study has shown immunity against hepatitis B is not usually assessed after immunization and a significant proportion of children who were adequately immunized are not adequately protected against HBV. A large-scale study would be desirable for confirmation.
COMMUNITY SOCIAL CONSTRUCTION OF THE REALITY OF THE MEANING OF TLEMBOK IN THREE DISTRICTS (Pekalongan, Pemalang and Tegal.)
Authors: Elisabeth Diva
Published: June 2023

The community's point of view in interpreting something is, of course, different between districts and sub-districts. Differences in meaning when talking to someone with a different understanding will change that person's meaning. "Tlembok" may not be popular among urban people or outside Java. Unlike the Regencies of Pekalongan, Pemalang, and Tegal, "Tlembok" has a different perspective in interpreting or interpreting it. This difference in meaning is, of course, an interesting issue to examine in more depth what the meaning of "Tlembok" is. This research was done to know what "Tlembok" means in the Pekalongan area, Pemalang, and Tegal, and how the origins of why the fried food is named plaster by using Peter L Berger's theory of social reality construction. This study uses a qualitative method with a descriptive approach, which focuses more on collecting and analyzing data in numbers than the data processed, from examination to modeling. The results of this analysis indicate that the meaning of "Tlembok" in West Pekalongan Regency and Pemalang Regency is fried food made from leftover tofu dregs and also tempeh dregs which are then processed again to become Tlembok. Meanwhile, in Tegal and East Pekalongan Regencies, Tlembok means prostitutes, night butterflies, Jablay, and the like. The origin of this fried food is called Tlembok because it is made from leftover tofu dregs and leftover dregs from making tempeh, which is likened to a woman who often plays sex or includes leftovers from other people.

The Effects of Charismatic Aspects of Transformational Leadership on Personal Outcomes: An Empirical Literature Review
Authors: Chunhui Lin , Azar Ali Sorayyaei , Ahmad Albattat
Published: June 2023

Idealized influence, combined with inspirational motivation, constitutes the charismatic-based aspect of transformational leadership. However, few researchers examined the influence of these two traits exerting on the employee’s personal outcomes in the workplace and more research should be conducted. The goal of this paper turns to identify and analyze empirical articles on the effect of the charismatic aspect of transformational leadership on personal outcomes from the year 2013 to 2022. Such online databases like Google Scholar, ERIC, Web of Science and ProQuest were used to collect the literature. Induction analysis, narrative synthesis was utilized to analyze the articles and three conclusions can be drawn: 1) A positive impact of Idealized influence and inspirational motivation on related personal outcomes like job performance, job satisfaction and the job engagement was confirmed but the impact on job performance seems having received more concerns than the influence on job satisfaction and the engagement. 2) Most of the research are conducted in countries like Kenyan, Indonesia, Yemen, Jorden. Industries mainly involved in business sector like state-owned enterprises and private businesses, so the research context should be expanded to other places and countries and include more industries. 3) Future researchers are advised to concentrate more on the influence of idealized influence and inspirational motivation on personal outcomes such as job satisfaction, job engagement, job commitment, and the explanatory mechanism need to be more creative and innovative when supporting with a new theoretical foundation.
Beyond the First Tipping Points of Southern Hemisphere Climate
Authors: O'Kane Terence , Frederiksen Jorgen , Frederiksen Carsten , Horenko Illia
Published: June 2023

Analysis of observations, reanalysis and model simulations, including via machine learning methods specifically designed for regime identification, have revealed changes in aspects of the Southern Hemisphere (SH) circulation and Australian climate and extremes over the last half century that point to transitions to new states. In particular, our analysis shows a dramatic shift in the metastability of the SH climate occurred in the late 1970s, associated with a large scale regime transition in the SH atmospheric circulation with systematic changes to the subtropical jet, blocking, zonal winds and storm tracks. Analysis via nonstationary clustering reveals a regime shift was coincident with a sharp transition to warmer oceanic sea surface temperatures and increased baroclinicity in the large scales of the Antarctic Circumpolar Circulation (ACC), extending across the whole hemisphere. At the same time, the background state of the tropical Pacific thermocline shoaled, leading to increased likelihood of El Ni\~{n}o events. These changes in the dynamics have preceded additional regional tipping points associated with reductions in mean and extreme rainfall in South-west Western Australia (SWWA) and streamflow into Perth dams, and also with increases in mean and extreme rainfall over Northern Australia since the late 1970s. The drying of South-eastern Australia (SEA) occurred against a background of accelerating increases in average and extreme temperatures across the whole continent since the 1990s, implying further inflection points may have occurred. Through climate model simulations capturing the essence of these observed shifts our analysis indicates these systematic changes will continue into the late 21st century under high greenhouse gas emission scenarios. Here we review two decades of work, revealing for the first time, that tipping points characteristic of first and second order regime transitions are inferred to have already occurred in the SH climate system.
The Influence of Hatha Yoga on Stress, Anxiety, and Suppression: A Randomized Controlled Trial

Published: June 2023

Engaging in yoga may mitigate stress and anxiety in individuals. It can also potentially enhance one's capacity to manage distractions. Our research aimed to explore the relation between these two outcomes: Can an eight-week yoga program foster distraction suppression, thereby reducing stress and discomfort? To answer this question, we used Hatha Yoga, the most commonly practiced form of Yoga. We tested if the intervention improved participants’ ability to selectively suppress distractions, and decreased self-reported stress and stress reactivity, besides increasing mindfulness. Our study included 98 healthy yoga novices between 18 and 40 years that were randomly assigned to either an experimental or a waitlist condition, with each participant completing pre- and post-intervention assessments of said functions, including questionnaires, electrophysiological and behavioral measures. After eight weeks of yoga practice, significant reductions in self-reported stress and stress reactivity levels, as well as increased mindfulness were observed among those receiving the intervention relative to those in the waitlist control group; however, there were no significant changes in state, nor trait anxiety due to the intervention. Also, the stress changes did not correlate with increased suppression in the experimental task: Suppression was not affected by our intervention and was not responsible for found stress reductions. Overall, our findings suggest that regular participation in Hatha Yoga can improve mental health outcomes, without impacting cognitive functioning directly related to distractor suppression.
From Everyday Exposure to Pragmatic Mastery: The COME Perspective
Authors: Wermelinger Stephanie , Daum Moritz M. , Gampe Anja
Published: June 2023

In this paper, we review recent findings on the development of communicative behaviour of monolingual and bilingual toddlers and preschoolers. We describe how the unique experience of growing up with two (or more) languages affects children’s everyday experiences and the pragmatics of their communicative behaviour. Deriving from this literature, we introduce a novel perspective on children’s development of communicative behaviour (COMmmunicative-Experience, COME), discussing potential mechanisms behind this pragmatic behaviour. It assumes that children experience communicative situations of varying efficiency and that these experiences shape their communicative behaviour: The more experiences children have with non-effective communicative situations, the larger their communicative repertoire becomes and the more flexibly this repertoire can be applied in a given situation. Notably, the COME perspective is not limited to bilingual communicative development but can be applied to a variety of other pragmatic contexts. Therefore, we broaden the discussion by identifying open questions for future research.
Effects of Basic Metronomic Meters on Beat-Synchronized Walking
Authors: Shay Gregory Dean
Published: June 2023

Background: This study was conducted to determine if a basic component of rhythm and music can elicit the human urge to move in time with the beat. Beat supports meter, meter supports rhythm, and rhythm is an indispensable element of music. Groove music – music that elicits the pleasurable urge to move – has one or more stimulating quality elements, and certain rhythms have been strongly associated with the groove phenomenon. In this study, a range of basic meter – meter without secondary accenting and therefore without rhythm – is created with, and along with metronome and examined for effect on synchronous walking speed. A comparison is made with quadruple meter groove music and a free walking silent condition at equivalent cadence.Methods: Employing a single–case full factorial design randomized with six replicates for each paired tempo–meter condition, participant synchronous walking speeds were examined at four metronome tempi (112, 116, 117, and 120 bpm) and seven basic meter time signatures of increasing beat homogeneity (2/4, 3/4, 4/4, 5/4, 7/4, 10/4, and [no meter] plus stimulating 4/4 music and a linear regression determined silent condition. Internal basic meter was created by repetitively whisper counting time signatures over conventional metronome beats. External basic meter was created with an accenting metronome at one tempo (116 bpm). With walking confirmed at 100% synchrony and the 2.044 mi lap distance a constant, average lap speeds for each paired condition were determined from lap times with high accuracy. Results: Over the range of increasing metronome time signatures from 2/4 to [no meter], a peak in walking speed was observed at 4/4 meter for even tempi and at 3/4 meter for the single odd tempo of 117 bpm with peak meters nearly as stimulating as the 4/4 music. The results for external and internal meter were quite similar, and as time signatures increased beyond the speed apex, vigor declined to the approximate level of [no meter] and the silent condition. The 2/4 time signature seemed an anomaly as it was without stimulating quality similar to [no meter].Conclusions: 1) basic meters at or adjacent to the 4/4 time signature are quite stimulating, 2) stimulating basic meters are a potential underlying element of groove, 3) the stimulating quality of quadruple meter supports a human preference for a four-beat meter, and 4) basic meters with high beat homogeneity lack stimulation Potential Benefits: The findings of this study may have performance implications for walkers, runners, and perhaps others engaged in rhythmic physical activities. The findings may also contribute to a further understanding of the human auditory sensorimotor system and to possible intervention for human gait disorders.
Contextual coherence increases perceived numerosity independent of semantic content
Authors: Qu Chuyan , Bonner Michael F. , DeWind Nicholas K. , Brannon Elizabeth M.
Published: June 2023

Number perception emerges from multiple stages of visual processing. Understanding how systematic biases in number perception occur within a hierarchy of increasingly complex feature representations helps uncover the multi-stage processing underlying our visual number sense. Recent work demonstrated that reducing coherence of low-level visual attributes such as color and orientation systematically reduces perceived number. Here we ask when in the visual processing hierarchy coherence affects numerosity perception and specifically whether the coherence effect is exclusive to low-level visual features or instead whether it can be driven by contextual or semantic relationships. We tested adults in an ordinal numerical comparison task with contextual coherence mathematically manipulated using a statistical model of visual object co-occurrence. Across several experiments, we found that arrays with high contextual coherence were perceived as numerically larger than arrays with low contextual coherence. This contextual coherence effect was not attenuated even when we reduced objects to texforms (unrecognizable images that preserve mid-level visual features) or removed semantic content from the images through box scrambling and diffeomorphic warping. Together, these results suggest that visual coherence derived from natural statistics of object co-occurrence systematically alters perceived numerosity at low-level visual processing, even before later stages at which items can be explicitly categorized and identified.
A Multi-Modal Assessment of Fear Conditioning in Adolescent Anorexia Nervosa
Authors: Murray Stuart B , Strober Michael , Le Grange Daniel , Schauer Rebecca , Craske Michelle , Zbozinek Tomislav
Published: June 2023

Background: Anorexia nervosa (AN) is a pernicious psychiatric disorder which is principally characterized by a fear of weight gain. Notwithstanding the centrality of fear in the psychopathology of AN, controlled assessments of negative valence systems are lacking. Herein we investigate whether deficits in either fear acquisition or fear extinction are evident among adolescent females with AN.Methods: Adolescent girls (Mage = 14.6 years) with DSM-5 diagnoses of AN (N=25) and age-matched control girls (Mage = 14.8 years) with no DSM-5 diagnoses (N=25) completed structured clinical interviews and participated in a classical three-phase Pavlovian fear conditioning paradigm. Skin conductance response (SCR) was measured, alongside self-reported fear, valence and fear expectancy ratings.Results: Both groups demonstrated significant differential acquisition across all four measures. Regarding group comparisons, no differences emerged for self-reported fear, valence and fear expectancy ratings during acquisition, although for SCR, those with AN demonstrated reduced physiological arousal relative to controls. Both groups demonstrated significant differential extinction for US expectancy, self-report fear, and self-report valence. No statistically significant group differences were evident during extinction to the CS+, on any outcome measure. However, controls reported more positive valence to the CS- than those with AN.Conclusions: Contrary to our hypotheses we did not find support for elevated fear responding among adolescent girls with AN with regards to fear acquisition or extinction. These data do not support the notion that elevated fear acquisition underpins AN psychopathology, but suggest that exposure treatments may be helpful, since extinction learning is intact in AN.
German-Style Shadow Education: The Role of Private Tutoring for School Allocation in a Highly Stratified Education System
Authors: Entrich Steve Richard , Lauterbach Wolfgang
Published: June 2023

The present article aims to contribute to research on extended education and inequality in educational attainment in two ways: First, we draw on insights from two competing theoretical strands of argumentation from social stratification and mobility research to better explain the role of ‘shadow education’ (SE) for educational success in a highly stratified education system. Second, we empirically examine the effects of SE on the transitions to upper secondary and tertiary education using data from the German National Education Panel Study (NEPS). We provide a first empirical study on the impact of SE on school allocation in this country.Contrasting to international results, our findings show that SE in Germany is primarily used by low performing students who seek to complete their school degrees before leaving the education system—largely independent of their socioeconomic status (SES). Effects of SE on upper secondary school and university transition are generally negative and more pronounced among more selective institutions. Our analyses further confirm the higher likelihood of high SES students to achieve higher vertical and horizontal educational outcomes, but cannot confirm any role of SE for success in the allocation process.In conclusion, our results stronger support a social mobility perspective, indicating that low SES strata are equally likely to achieve their (relatively higher) educational goals through SE, but do not advance to educational tracks with the highest expectable returns.

Authors: Rizkiyah Fitri , Ristanto Rizhal Hendi , Miarsyah Mieke
Published: June 2023

Plant classification material is one of the materials listed in the basic competence of the curriculum applied in Indonesia and is less attractive to students because the characteristics of plants are quite difficult to identify so that the classification is complicated. It is known that most middle-level students really like games which are integrated in learning activities. Therefore, this study aims to develop a media called Plant-Puzzle Games (PPG) which is expected to have a positive effect in the form of increasing the learning motivation of junior high school students in studying plant classification material. The research method used in this study is a research and development method with the ASSURE model as the research design. Based on the results of the media validation test by experts, an average value of 3.25 was obtained, which indicates that the media was included in the valid category. Based on the results of the effectiveness test with the calculation of N-Gain, the average value is 0.49. This shows that, after using PPG media, the learning motivation of students has increased which is in the sufficient category.

This study sought to identify the effect of using alternative evaluation in improving educational outcomes. (Cognitive, psychological, skill) for university courses for students (the scientific research methodology course as a model). To achieve the objectives of the study, the researchers used the quasi-experimental method. The sample of the study consisted of (40) students enrolled in the course of scientific research methods at Al- Istiqlal University. They were distributed randomly into two groups: the experimental group used the alternative evaluation.  However, the control group used traditional evaluation. The results of the study showed that there is an effect of using the alternative evaluation in improving the educational outcomes (cognitive, psychological, and skills) of the experimental group students. In light of these results, the researchers recommended a review of current evaluation practices that use traditional tests.  In addition, there is a need to amend the regulations and instructions regulating the evaluation policy in accordance with the university's modernization and developing in line with modern strategies for evaluation, and the use of alternative evaluation tools in evaluating students' work in university courses.

Impact of National Election-2017/18 on Corporate Performance: An Analysis of Insurance Companies in Nepal
Authors: Oli Sudan Kumar
Published: June 2023

This paper analyzes the impact of the national election on corporate performance by using panel data from listed insurance companies over the period 2015 to 2021 with 126 observations. The proxy variables of corporate performance have used market price per share (MPS), dividend payout ratio (DPS), and return on assets (ROA) for market performance, investor’s performance, and firm’s performance respectively. This study uses the generalized least squared (GLS) method for the final impact assessment. Empirical analysis shows that the beta coefficient of D-election is significantly negative with all performance proxy variables in random effect estimates. This indicates that there is a random effect of the national election on corporate performance and provides a negative impact on corporate performance after the national election-2017-18. Similarly, analysis of fixed effects also support a similar impact except for the DPS because DPS is not significant. For the robust test, this paper has performed the Breusch-Pagan test and Hausman test which supports consistency of the analysis. Overall analysis suggests that the four levels of elections: local level, provincial level, federal level, and national assembly election do affect adversely the corporate performance of insurance industries in Nepal.
