Authors: Putri Anisa
Published: June 2023

Strategi pembelajaran konvensional adalah strategi pembelajaran yang menekankan kepada proses penyampaian materi secara verbal dari seorang guru kepada siswa agar dapat menguasai materi pembelajaran secara optimal menurut suparman(2021) bahwa strategi pembelajaran berkenan dengan pendekatan dalam mengajar dengan mengelola kegiatan pembelajaran untuk menyampaikan materi secara sistematis sehingga dapat dikuasai oleh siswa secara efisien.Motorik merupakan perkembangan pengendalian gerakan tubuh melalui kegiatan yang terkoodinir antara susunan saraf,otot dan perkembangan motorik.Motorik meliputi motorik kasar dan halus motorik kasar adalah gerakan tubuh yang menggunakan otot besar yang dipengaruhi oleh kematangan anak itu sendiri.Perkembangan motorik anak dibagi menjadi dua 1) Keretampilan atau gerakan. 2) Keterampilan motorik halus atau keterampilan manipulasi. Perkembangan motorik anak berbeda setiap individu setiap anak yang memiliki keterbatasan fisik berpengaruh dalam perkembangan motorik.Perkembangan motorik beriringan dengan proses pertumbuhan secara genetis atau kematangan fisik anak.
A unifying method to study Respiratory Sinus Arrhythmia dynamics implemented in a new toolbox
Authors: Ghibaudo Valentin , Granget Jules , Dereli Matthias , Buonviso Nathalie , Garcia Samuel
Published: June 2023

Respiratory sinus arrhythmia (RSA), the natural variation in heart rate synchronized with respiration, has been extensively studied in emotional and cognitive contexts. Various time or frequency-based methods using the cardiac signal have been proposed to analyze RSA. In this study, we present a novel approach that combines respiratory phase and heart rate to enable a more detailed analysis of RSA and its dynamics throughout the respiratory cycle. To facilitate the application of this method, we have implemented it in an open-source Python toolbox called physio. This toolbox includes essential functionalities for processing ECG and respiratory signals, while also introducing this new approach for RSA analysis. Inspired by previous research conducted by our group, this method enables a cycle-by-cycle analysis of RSA providing the possibility to correlate any respiratory feature to any RSA feature. By employing this approach, we aim to gain a more accurate understanding of the neural mechanisms associated with RSA.

Authors: Sumirah R.R. Dhewi Putri Ayu
Published: June 2023

Dalam perspektif Islam, kebijakan moneter harus diatur dengan prinsip-prinsip syariah yang melarang praktik riba dan gharar. Bank sentral dalam sistem ekonomi Islam harus memastikan bahwa kebijakan moneter yang diterapkan tidak merugikan masyarakat dan tidak mengarah pada praktik riba. Selain itu, bank sentral juga harus memastikan bahwa pasokan uang diatur dengan baik agar tidak terjadi inflasi atau deflasi yang berlebihan. Bank sentral juga harus memperhatikan stabilitas nilai tukar mata uang agar tidak terjadi ketidakstabilan ekonomi yang merugikan masyarakat. Dalam ekonomi Islam, kebijakan moneter juga harus memperhatikan distribusi kekayaan yang adil dan mengurangi kesenjangan sosial. Dengan menerapkan kebijakan moneter yang sesuai dengan prinsip-prinsip syariah, ekonomi makro Islam dapat menciptakan lingkungan bisnis yang adil dan berkelanjutan, serta memberikan manfaat bagi seluruh masyarakat.

Predictors of Listening-Related Fatigue in Adolescents with Hearing Loss
Authors: Klein Kelsey , Harris Lauren , Humphrey Elizabeth , Noss Emily , Sanderson Autumn , Yeager Kelly
Published: June 2023

Purpose: Self-reported listening-related fatigue in adolescents with hearing loss (HL) was investigated. Specifically, the extent to which listening-related fatigue is associated with school accommodations, audiologic characteristics, and listening breaks was examined.Method: Participants were 144 adolescents with HL, ages 12-19. Data were collected online via Qualtrics. The Vanderbilt Fatigue Scale-Child Version was used to measure listening-related fatigue. Participants also reported on their use of listening breaks and school accommodations, including an Individualized Education Program (IEP) or 504 plan, remote microphone system, closed captioning, preferential seating, sign language interpreter, live transcription, and note taker.Results: After controlling for age, HL laterality, and self-perceived listening difficulty, adolescents with an IEP or 504 plan reported lower listening-related fatigue than adolescents without an IEP or 504 plan. Adolescents who more frequently used remote microphone systems or note takers reported higher listening-related fatigue than adolescents who used these accommodations less frequently, whereas increased use of a sign language interpreter was associated with decreased listening-related fatigue. Among adolescents with unilateral HL, higher age was associated with lower listening-related fatigue; no effect of age was found among adolescents with bilateral HL. Listening-related fatigue did not differ based on hearing device configuration.Conclusions: Adolescents with HL should be considered at-risk for listening-related fatigue regardless of the type of hearing devices used or the degree of HL. The individualized support provided by an IEP or 504 plan may help alleviate listening-related fatigue, especially by empowering adolescents with HL to be self-advocates in terms of their listening needs and accommodations in school. Additional research is needed to better understand the role of specific school accommodations and listening breaks in addressing listening-related fatigue.
Behavioural expressions of loss-chasing in gambling: A systematic scoping review
Authors: Banerjee Nilosmita , Chen Zhang , Clark Luke , Noël Xavier
Published: June 2023

Loss-chasing, the tendency to continue and/or intensify gambling following losses, is a key clinical symptom in gambling disorder and a central feature in problem gambling, endorsed by at-risk problem gamblers. Despite its centrality, the extant literature has often operationalised loss-chasing across distinct behavioural expressions. The current systematic scoping review aimed to map the heterogeneous operationalisations of loss-chasing in the literature. The reviewed studies defined loss-chasing either between-sessions (n=39) or within-sessions (n=38), as a long-recognised distinction. For both categories, further behavioural expressions could be distinguished. Between-session loss-chasing was captured by endorsing an item ‘returning another day/time to recoup losses’, or behaviourally as the interval between successive sessions, or as increasing stakes on the next visit. Within-session loss-chasing was defined as continuing to gamble, and/or intensifying betting either by increased risk-taking, stake size, or speed of play. Additionally, much heterogeneity was observed in gambling contexts examined, the exact definition of loss, and the potential delineation of win-chasing. Open questions and future directions are discussed. Overall, this paper severs as a first step towards more conceptual clarity of loss-chasing.
Social recovery in psychosis: Evaluating the validity of the short form Social Role Participation Questionnaire (s-SRPQ)
Authors: Wierdsma André I. , Rietveld R. , van Aken B.C.
Published: June 2023

The Social Role Participation Questionnaire (SRPQ) was developed to assess role salience, physical difficulties, and satisfaction with role performance across different domains in patients with arthritis. In this study, the shortened version of the SRPQ was used to evaluate the validity of the questionnaire in patients diagnosed with a psychotic disorder. Data from 298 patients participating in an observational cohort study of recovery processes over time were used to investigated the validity and temporal stability of several indicators of social role participation. Correlations were low between satisfaction with role performance and role salience and between role salience and physical difficulty. More satisfaction corresponded to less physical difficulties. Temporal stability analysis showed no reliable change for sum scores or averaged scores, but a categorical approach showed less role participation for 18.5% of patients whereas 30.4% improved to partial or full social recovery after twelve months. Convergent validity estimates showed moderate associations and concurrent validity was considered adequate: 65% of patients in clinical remission showed partial or full social recovery and personal recovery scores correlated .40 to .45 with role participation indices. We conclude that the s-SRPQ can be used for measuring social recovery in psychiatric patients, in the process of which different indices could be applied.
“It’s illegal to buy drugs from street dealers” - A Video-Based Pre-Post Study of a Behavioral Intervention to Displace Dealers from an Amsterdam Open-Air Drug Market
Authors: Ejbye-Ernst Peter , Moeller Kim Kristian , Liebst Lasse Suonperä , Thomas Josephine , Sexton Melissa M. , Lindegaard Marie Rosenkrantz
Published: June 2023

Objectives: A high number of street dealers operate in the Red Light District in Amsterdam, The Netherlands. To displace the dealers, the Municipality of Amsterdam installed text-based light projections in a street attracting a high number of dealers. Methods: To evaluate the intervention, we did a pre-post analysis of video footage from two CCTV cameras located in the street. In total, we analyzed 765 one-minute segments of footage from before and after the implementation.Results: The implementation was followed by a four percentage point reduction in street dealers. However, the estimated effect shows fragileness with wide confidence intervals, a p-value just below 0.05, and a Bayesian robustness analysis suggests that the intervention was not associated with the outcome.Conclusions: Analyzing CCTV-footage offers a unique avenue for evaluating small scale interventions in open-air drug markets. While we observed a decrease in the presence of dealers, the intervention still needs further validation.
Normal Congruency Sequence Effects in Psychopathology: A Behavioral and Electrophysiological Examination Using a Confound-Minimized Design
Authors: Clayson Peter E , Shuford John , Rast Philippe , Baldwin Scott , Weissman Daniel H. , Larson Michael J.
Published: June 2023

Clinical studies of adaptive control emphasize the role disruptions in control play in psychopathology. However, many studies used confound-laden designs and examined only one type of psychopathology. Recent studies of event-related potentials (ERPs) suggest that robust congruency sequence effects (CSEs) – a popular index of adaptive control – appear in confound-minimized designs. Thus, the present study sought to determine whether a confound-minimized CSE paradigm could identify adaptive control dysfunction in people with major depressive disorder (MDD), generalized anxiety disorder (GAD), and obsessive-compulsive disorder (OCD). We predicted that participants with MDD and GAD would show smaller ERP CSEs and that participants with OCD would show larger ERP CSEs than healthy controls. Data from 44 people with GAD, 51 people with MDD, 31 people with OCD, and 56 healthy comparison participants revealed normal CSEs as indexed by response times (RTs) and ERPs in the psychopathology groups. Moreover, psychiatric symptoms did not moderate these CSEs. Finally, we observed a strong mean-variance relationship in RT CSEs, such that participants with stronger post-recruitment of control in mean RT scores showed the most consistent post-conflict responses (i.e., the least intraindividual variability). These findings suggest that prior findings from confound-laden tasks indicating altered CSEs in psychopathology stem from processes that are unrelated to adaptive control. Future research should employ experimental designs that isolate these processes to advance our understanding of abnormal CSEs in psychopathology.
“It’s Like Coding in the Dark”: The need for learning cultures within coding teams
Authors: Hicks Catherine
Published: June 2023

This report presents data from a qualitative research project with software engineers anddevelopers. Twenty-five full-time code writers completed a “debugging” task and an in-depthinterview on their learning, problem-solving, and feedback experiences while onboarding to anunfamiliar, collaborative codebase. This report applies a learning science lens to inform anunderstanding of how to help code writers can thrive and collaborate.● Themes from these interviews revealed an important learning tension: the work that codewriters needed to do to understand code often did not feel like what was rewarded in theevaluation of their work. Code review often did not recognize code writers’ effort when it didnot result in lines of code. Despite stated ideals about knowledge sharing (e.g., documentationand collaboration), this work was often contradicted with negative cues from colleagues aboutwhat was “truly” valued. This tension was exacerbated by code writers’ fears about “not lookinglike an engineer,” and their desire to perform to the expectations of their environments.● Code writers navigated this by divesting from their own learning and from the “invisible” work ofknowledge transfer, leaving future collaborators without guidance in their own ramp-up tounfamiliar code. As a result, code writers frequently expressed a poignant loneliness, even inhighly resourced teams.● This maladaptive cycle can be understood as Learning Debt. Research from learning sciencedescribes how environments that discourage sharing mistakes and valuing “in-draft” effort leadto long-term costs in people’s motivation, wellbeing, and learning. Under this discouragement,even formal processes which are ostensibly meant to maintain productivity and provide support(e.g., code review, conversations with senior code authors) can reinforce these negative norms.
Development and validation of Emotional Climate Change Stories (ECCS) stimuli set
Authors: Zaremba Dominika , Michałowski Jarosław M. , Klöckner Christian Andreas , Marchewka Artur , Wierzba Małgorzata
Published: June 2023

Climate change is widely recognized as an urgent issue, and the number of people concerned about it is increasing. While emotions are among the strongest predictors of behaviour change in the face of climate change, researchers have only recently begun to investigate this topic experimentally. This may be due to the lack of standardised, validated stimuli that would make studying such a topic in experimental settings possible. Here, we introduce a novel Emotional Climate Change Stories (ECCS) stimuli set. ECCS consists of 180 realistic, short stories about climate change, designed to evoke five distinct emotions - anger, anxiety, compassion, guilt, and hope - in addition to neutral stories. The stories were created based on qualitative data collected in two independent studies: one conducted among individuals highly concerned about climate change, and another one conducted in the general population. The stories were rated on the scales of valence, arousal, anger, anxiety, compassion, guilt, and hope in the course of 3 independent studies. First, we explored the underlying structure of ratings (Study 1; n = 601). Then we investigated the replicability (Study 2; n = 307) and cross-cultural validity (Study 3; n = 346) of ECCS. The collected ratings were highly consistent across the studies. Furthermore, we found that the level of climate change concern explained the intensity of elicited emotions. Altogether, the ECCS dataset is available in Polish, Norwegian and English and can be employed for experimental research on climate communication, environmental attitudes, climate action taking, or mental health and wellbeing.
Mental Accounting in Negotiations: Solving Negotiators’ Cognitive Dilemmas in Multi-Issue Negotiations
Authors: Zhang Hong , Warsitzka Marco , Majer Johann M. , Trötschel Roman
Published: June 2023

Five experiments (N = 1275) investigate how negotiators cognitively process proposals and outcomes when a broad set of issues are negotiated simultaneously. Based on seminal research on mental accounting, we predict that negotiators strive to reduce complexity in multi-issue negotiations by mentally creating subsets of issues (i.e., topical mental accounting; Thaler, 1999; Tversky & Kahneman, 1981). We propose that such mental accounting processes play out as a double-edged sword: creating mental accounts on issues that include the integrative potential within subsets of issues will help negotiators to reduce complexity and explore beneficial tradeoffs. By contrast, creating mental accounts on issues that scatter the integrative potential between subsets of issues will impede the discovery of win-win agreements. Experiment 1 explored the cognitive process of mental parsing (i.e., creating cognitive subsets of issues) in multi-issue negotiations. Experiments 2 and 3 investigated how the way the issue subsets were created impacted parties’ perceptions, behaviors, and outcomes. Experiments 4 and 5 sought to investigate a cognitive tool (i.e., integrated outcome editing, Thaler, 1999) that helps parties to overcome detrimental effects arising from the mental accounting process. Overall, our findings highlight when, how, and why mental accounting helps versus hurts negotiators in complex multi-issue negotiations.
Processing fluency for visual synchrony perception
Authors: Bamford Joshua Silberstein , Tarr Bronwyn , Cohen Emma
Published: June 2023

Prior research has found that interpersonal synchrony increases social closeness and cooperation: this is often referred to as the synchrony-bonding effect. Most explanations for this synchrony-bonding effect rely upon higher-order social cognition (e.g. shared goals or self-other merging). Relatively little attention has been given to the perceptual experience of synchrony, and the low-level perceptual mechanisms involved, such as processing fluency. In two pre-registered experiments, we tested the novel hypothesis that synchrony (congruent movement) is easier to process than non-synchrony. In Study 1, no effect of direction congruency on performance was detected. However, Study 2 found a significant effect of speed congruency. This indicates decreased processing load when stimuli are moving at the same speed. We then discuss how these reduced visual stimuli may relate to naturalistic periodic movement. Crucially, the effect observed here does not rely upon social stimuli and may operate at an early stage of perceptual processing. This is an initial step in establishing a novel theory of the synchrony-bonding effect, based upon the principles of processing fluency.
Why targeting attitudes often fails to elicit sustainable tourist behaviour
Authors: Dolnicar Sara , Demeter Csilla
Published: June 2023

Recent reviews of field experiments aiming to entice tourists to behave in more environmentally sustainable ways conclude that attitudes – while the primary target – do not perform as well as expected. This critical review analyses in detail when attitudes have or have not been successful as behavioural change targets and proposes a conceptual framework of possible explanations. In so doing, the study represents the first theoretical – rather than empirical – challenge to the currently dominant theoretical understanding of environmentally significant tourist behaviours and offers alternative theoretical constructs tourism researchers aiming to make tourists behave in more sustainable ways could investigate in future.We investigate in detail experiments where attitude-based behavioural change approaches failed. Based on the insights from this analysis, we propose a conceptual framework offering five potential explanations. We also discuss alternative theoretical constructs that could be used for behavioural change interventions. We derive five potential explanations for why attitudes often fail to trigger behavioural change in the context of environmentally sustainable tourist behaviour: tourists do not notice messages attempting to change their attitudes; tourists are unwilling to cognitively process behavioural change messages; tourists develop reactance to behavioural change requests; attempts to alter attitudes do not influence habits; attempts to alter attitudes do not reduce the effort associated with displaying the desired behaviour. This is the first theoretical investigation of possible reasons why attitudes have performed poorly as targets of behavioural change interventions aiming to trigger environmentally sustainable tourist behaviours. Implications – This critical review broadens research attention to alternative theoretical constructs that may be more effective in making tourists behave in more sustainable ways and opens opportunities for new measures tourism businesses and destinations can implement to influence tourist behaviour.

Introduction/framework/objectives Sometimes some oncological pathologies may be associated with certain working conditions; in relation to Ovarian Cancer, publications are scarce. The aim of this review was to summarize what was most relevant in relation to this topic. Methodology This is a Bibliographic Review, initiated through a search carried out in January 2022 in the databases “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina and RCAAP”. Content Ovarian Cancer is the 6th or 8th most common in females worldwide and the fifth most frequent in Europe and USA, that is, it is responsible for about 4% of female oncological pathology. Of all gynecological cancers, it has the highest mortality. Discussion and Conclusions Although some defend that there have been no proven associations between some work characteristics and this pathology; others highlight asbestos, talcum powder, trichlorethylene, silica and ionizing radiation, as well as shift work. However, the relationships are complex. It would be desirable for the topic to be further investigated and the data disseminated, so that scientific knowledge progresses and workplaces become a little safer. KEYWORDS: ovarian cancer, occupational health, occupational medicine and safety at work.

BIG DATA SUPPORT FOR PROJECT MANAGEMENT IN THE CONDITIONS OF WAR: THE EXPERIENCE OF UKRAINE
Authors: Horobets Olena  , Motuzka Olena
Published: June 2023

The article contains a review of the unique Ukrainian experience of launched and implemented projects in the conditions of a global risk, i. e. the war. It is highlighted that the large-scale invasion of the Russian Federation on the Ukrainian territory caused global threats and risks for public and business organizations and the Ukrainian society as a whole. The emphasis is made on top innovative projects of Ukraine launched and implemented (or being rapidly developed) due to the intensive use of digitalized processes. The authors presented a review of global reforms in the areas of strategic importance for Ukraine: development of road infrastructures in Ukraine, modernization of heath protection sector, reduction of Ukraine’s dependence on energy imports (especially on Russia), development of digitalized processes, improvement of the education quality and bringing the domestic education system in conformity with European standards. These reforms involved the development of megaprojects that could be successfully implemented several years before the beginning of the war and continue to be extensively used in daily activities of Ukrainian citizens. The issue of big data implementation as a useful ground for the successful accomplishment of projects in the conditions of war and the future postwar period is elaborated on.
DISEASE HISTORY OF A COMORBID PATIENT

Published: June 2023

In real clinical practice, more and more doctors encounter comorbid pathology. The combination of cardiovascular diseases with the pathology of other internal organs dictates the need to prescribe a variety of drugs. A comorbid patient is a serious problem for any clinician, since in this case it is necessary to take into account several components of therapy, which makes it difficult to control the effectiveness of the treatment, increases polypharmacy, the likelihood of developing local and systemic side effects of drugs, and also reduces adherence to therapy. The article presents a discussion of the clinical case of a comorbid patient, which required a broad outlook of the therapist in the field of not only cardiological aspects of diagnosis and treatment, but also nephrological, rheumatological. The stages of the performed diagnostic search with the verification of the clinical diagnosis and the tactics of the prescribed pharmacotherapy are given. Based on the presented data, it is shown that in conditions of comorbidity it is difficult for a doctor to avoid polypharmacy.
