When conducting forensic examinations of cultural property, various scientific and technical methods are used, including traceological research methods developed within the framework of forensic science. Traceological research methods are used, in particular, when it is necessary to study knots and loops: analyzing the images of knots and loops in works of painting, graphics, sculpture when resolving disputes regarding the attribution of products; decorative antique objects made using cords, ropes, threads, modern art installations; antique items of historical value. In this case, mainly classification and diagnostic tasks are solved. In some rare cases, identification problems can also be solved using the existing reference and information databases of knots and other fastening methods available to forensic tracers. New possibilities for studying knots and their images using artificial intelligence technologies seem promising.

Published: August 2024

This research aims to analyze the challenges and implementation of human rights in the personality development of elderly prisoners in Merauke Class IIB Prison. The research is limited to two main questions: How is, the personality development of elderly prisoners carriedis  out in the Merauke Class IIB Prison? Secon., what challenges are faced in implementing human rights in providing personality development to elderly prisoners in Merauke Class IIB Prison? This empirical juridical research examines legal regulations based on cases related to the implementation of personality development for elderly prisoners in Merauke Class IIB Prison. The research results show that first, the personality development activities for elderly prisoners carried out by the Merauke Class IIB Prison are limited to spiritual and moral development through direct and familial interaction between facilitators and inmates, systematic and planned development, and individual and group approaches. Second, Merauke Class IIB Prison faced several challenges in implementing human rights for elderly prisoners, such as inadequate provision of facilities and infrastructure, lack of socialization about human rights, which results in officers being less aware of prisoners' rights, and deficiencies in human resource capabilities and skills Necessary to direct organizational goals. Researchers suggest that the implementation of personality development for elderly prisoners must strictly adhere to the Minister of Law and Human Rights Regulation Number 32 of 2018. Every article in it can be taken carefully.

Authors: Mohammed Omar Abbas , Salih Ameen Ameen Mohammed
Published: August 2024

The governing differential equations about the seepage were resolved using the standard numerical. The research location was on the Darbandikhan dam, which is about 230 kilometres northeast of the governorate of Baghdad in the district of Sulaymaniyah on the Diyala River. The Geo-Studio program and its subprogram SEEP/W were used to examine the total water head through the dam and water flux, and exit gradient through the numerical model that represents the dam body to show how seepage affects the dam's stability. To run the dam numerical model, three upstream reservoir water levels at a Minimum water level of 434 m, Normal water level of 472 m, and flood water level of 485 m were selected to represent the model boundary conditions. Maximum total water head through the dam was found when the water level in the reservoir was 485 m while the maximum water flux through the dam was found when the water level in the reservoir was 472 m.  It was found the dam safety was ensured for all tested reservoir water levels.
Absurdities, Ironies, Hyper-Production and Artificial Bogeymen

Published: August 2024

This piece is an expanded version of a short letter to the editor about an article that appeared in Nature. The Nature article was titled "Is ChatGPT making scientists hyper-productive?" The original letter to the editor pointed out that the article made a temporal freeze frame error and was presented in a mode of disingenuous questioning that would hamper community wide self-examination into the issue of science production. The editors passed - no hard feelings. This piece expanded the letter to address issues related to what has come to be termed 'publication overload' (also called 'publication strain' in some studies).
Developing a Social Communication Screener for TBI
Authors: Birch Eleanor Scheidt , Stark Brielle C
Published: August 2024

Purpose:While speech-language pathologists (SLPs) play a pivotal role in identifying and treating social communication impairment in traumatic brain injury (TBI), there has been limited adoption of standardized assessments. SLPs report a lack of time, as well as a lack of competence in the administration of social communication assessments as primary barriers. Developing a feasible and valid screening tool is a viable solution to these barriers. The present study investigates a transcription-less rating scale as a screening tool for social communication impairment in TBI. Method:In a single-blind study, N=38 graduate clinicians listened to, and rated, six-minute conversation samples from ten speakers (5 TBI and 5 control [neurotypical]). Graduate clinician ratings were analyzed to determine if there were between-group differences in TBI and control speakers’ conversations, and whether raters had high agreement regarding speaker impairment. In addition, social communication ratings from the screener were compared to a gold standard of social communication measurement derived from transcribed analysis of the conversation samples. Results:Graduate clinicians significantly differentiated TBI from control speakers using the transcription-less rating scale and the ratings corresponded to patterns identified in the transcribed analyses. Given an exploratory “cut-off” score, raters identified speakers with TBI with 80% accuracy. Conclusions:These preliminary findings indicate that a brief, transcription-less rating scale holds promise to screen for social communication impairment in TBI to determine whether further assessment is warranted.
Emotion Regulation and Attachment as Mechanisms of Change in Schema Therapy and Cognitive Behaviour Therapy for Depression
Authors: Egli Samy , Badenbach Theresa , van Emmerik Arnold , Stefan Angelika Marlene , Kopf-Beck Johannes
Published: August 2024

Background. Psychotherapy is an efficacious treatment for depression; however, the rates of non-response and relapse remain unsatisfactory. In this study, we examined attachment and emotion regulation as two relevant mechanisms of change to improve treatment efficacy. We tested the hypotheses that schema therapy and cognitive behavior therapy have differential effects on these mechanisms, that changes in the mechanisms precede depressive symptoms and that the effects of schema therapy and cognitive behavior therapy on depressive symptoms are mediated by the mechanisms. Methods. We conducted a secondary analysis of data from a randomized controlled trial with 198 depressed patients treated with comprehensive psychiatric care and either schema therapy or cognitive behavior therapy for 7 weeks in an inpatient or day clinic setting. We calculated random intercept cross-lagged panel models (RI-CLPMs) within a Bayesian statistical framework separately for each of the mechanisms of change (anxious and avoidant attachment, emotion suppression and cognitive reappraisal). Results. The data did not support the hypotheses, but consistently supported the null hypotheses that schema therapy and cognitive behavior therapy do not have differential effects on the mechanisms of change, that the mechanisms of change do not predict subsequent symptom change, and that the mechanisms of change do not mediate treatment effects on depressive symptoms. Conclusions. Our analyses found that emotion suppression and cognitive reappraisal as emotion regulation strategies and avoidant and anxious attachment do not play a relevant role as mechanisms of change in psychotherapy for patients with depression in an inpatient or dayclinic psychiatric setting.
Introduction: "The Normalization of the Radical Right: A Norms Theory of Political Supply and Demand"
Authors: Valentim Vicente
Published: August 2024

Radical-right behavior is increasing across Western democracies, often very fast. Previous research has shown, however, that political attitudes and preferences do not change this fast. I argue that, to understand these patterns, one needs to appreciate the crucial role of social norms as drivers of political behavior. Building on a norms-based theory of political supply and demand, I argue that growing radical-right behavior is driven by individuals who already had radical-right views, but who did not act on them because they thought that they were socially unacceptable. If these voters do not express their preferences, politicians can underestimate how much latent support there is for radical-right policy. This leaves the radical right with less skilled leaders, who are unable to mobilize even radical-right voters to support them. However, if politicians realize that there is more private support for radical-right policy than is typically observable, they have an incentive to run for politics with a radical-right platform and mobilize silent radical-right views. Their electoral success, in turn, makes radical-right individuals become more comfortable showing their views, and impels more politicians to join the radical right. The argument of the book makes us rethink how political preferences translate into behavior, shows how social norms affect the interaction of political supply and demand, and highlights how a political culture that promotes inclusion can erode.
Sparse and Efficient Deep Neural Networks for remote PPg Applications
Authors: Ferreira Marlene , Gold Helene , Shah Aditya
Published: August 2024

This research presents an innovative approach to optimizing remote Photoplethysmography (rPPG) networks by employing pruning techniques. The goal is to create smaller, more efficient models that maintain high levels of performance, even with limited training data. The proposed method focuses on minimizing network complexity while preserving accuracy, making it particularly suitable for real-time applications. The study's experimental results demonstrate that the pruned networks can perform on par with their larger, more complex counterparts. This suggests that these streamlined models are a viable option for deployment in resource-constrained environments, where computational power and memory are limited. By achieving a balance between efficiency and accuracy, this research contributes to the practical application of rPPG technology in various real-world scenarios.
“There’s Only So Much the School Can Change About Itself… Before You Need to Change Something About Yourself”—a Qualitative Analysis of the Experiences of Neurodivergent Student Teachers
Authors: Jack Caryll , Crane Laura , Kenny Aisling , Blaisdell Caralyn , Davis Rachael
Published: August 2024

Background: In Scotland, to become qualified to teach children in primary schools (aged 4-11 years), student educators must complete degree programmes that include a combination of university and school-based placement learning environments. Previous studies have examined the experiences of neurodivergent students in other professional degree programmes, most notably in healthcare. Yet there is limited research considering the barriers and enablers for neurodivergent students in programmes leading to careers in education. Methods: This study contributes to the evidence base by examining the experiences of neurodivergent student participants from two Education Studies programmes run by one Scottish university: one including required professional placement experience in schools leading to professional teaching qualification status, and the other a theory-based course with flexible community placement options. Nine neurodivergent students, all originally following the professional placement strand, participated in a semi-structured interview. Data analysis was led by a neurodivergent educator, using reflexive thematic analysis. The resultant themes identified were named to reflect the lived experience of participants: Who we are matters; How we are matters; How we know matters and What we need matters. Results: Neurodivergent education students reported risk of withdrawal from and/or challenges within the professional strand programme, particularly emphasised in relation to placements. They felt that they needed to navigate additional systemic barriers to reach the same result as neurotypical peers. Further, they discussed how the accessibility and attitudes of others impact upon opportunities for disclosure, inclusion, and support. Our findings also suggest the possibility of an attitudinal hierarchy of neurodivergence acceptability occurring within educational environments. Conclusions: Neurodivergent students report a range of challenges when attempting to successfully complete education degree programmes leading to the teaching profession. Our findings identify the need for greater advocacy, support, and inclusion of neurodivergent participation, which attends to the nuanced experiences that education students face.
Retirement adjustment in the pandemic – did risk- and protective factors change?
Authors: Henning Georg , Segel-Karpas Dikla , Hyde Martin , Huxhold Oliver
Published: August 2024

The exit from the workforce and the transition to retirement often coincides with changes in important aspects of individuals’ daily life and social roles. This can be a demanding experience for some retirees, affecting their mental health. It is thus important to identify relevant psychosocial, health, and financial predictors of adjustment quality. Retiring during the Covid-19 pandemic may have been particularly challenging, as newly retired older adults had fewer opportunities to establish new leisure activities and social relationships due to limits on in-person meeting and travel. In the present study, we compared retirees who retired in or just before the first phase of the pandemic (2019-early 2021, n = 175) with those who retired long before the pandemic (2015-2017, n = 211) in terms of their retirement adjustment quality (reported in late 2020 / early 2021 or 2017, respectively). Retirement adjustment quality was measured by perceived adjustment difficulty and change in life satisfaction across the transition. We further investigated whether pre-retirement social activity, generalized self-efficacy, online activities or disease load were associated with later retirement adjustment in both groups. We found that groups did not differ in their retirement adjustment. In both groups, a higher generalized self-efficacy was associated with better adjustment. Social activities before retirement were only associated with increases in life satisfaction among those retiring before the pandemic. We discuss our findings with respect to the literature on predictors of retirement adjustment, as well as on the effects of the pandemic on psychosocial functioning.
Examining Linking Language and Causal Implications in Observational Psychological Capital Research
Authors: Mockett Elise , Williams Matt N , Gardner Dianne
Published: August 2024

The present study examines whether the issues with implied causal inference identified by Haber et al. (2022) in observational health research extend to the field of industrial-organisational (IO) psychology. Haber et al. found that causal relationships were implied through the language used to link exposures and outcomes and through recommendations for action. This small-scale conceptual replication applies Haber et al.’s approach to psychological capital (PsyCap), an increasingly popular construct in the domain of IO psychology. Specifically, we evaluate the causal strength of the language used to describe the nature of the connection between given variables when reporting findings and when making recommendations for action in 50 PsyCap articles. The majority of action recommendations were found to have strong causal implications (85% in abstracts, 84% in discussion sections), and most linking sentences implied some level of causality (64% in abstracts, 58% in discussion sections). This was despite very few articles explicitly stating an intention to estimate causal effects (10%) and many explicitly warning against drawing causal inferences (42%). No significant relationship was found between the causality implied in the linking sentences and the strength of causal implication of the action recommendations. These findings have important implications for how research is implemented, and very real consequences for those who are the focus of such implementations. Increased transparency about causal interests and reasoning is needed to uphold the credibility of findings and the integrity of applications of observational PsyCap research.
The light side of darkness? The dark triad of personality as positive and negative predictors of L2 language learning
Authors: Ebn-Abbasi Faramarz , Fattahi Nazila , Dewaele Jean-Marc , Botes Elouise
Published: August 2024

The duality of human nature, consisting of positive and negative personality traits, has intrigued a scholarly interest in different fields. Despite an overwhelming dominance of research on positive characteristics, particularly in the field of education, negative traits, such as those constituting the Dark Triad (DT; i.e. Psychopathy, Narcissism, and Machiavellianism) have been confirmed to be associated with both positive and detrimental outcomes. This paper aims to investigate the potential influence of these aversive traits on second language (L2) learning outcomes — i.e. L2 learning motivation, engagement, achievement, and willingness to communicate. L2 learners from a single country (n = 431) participated in this study. Multiple structural equation models (SEMs) were run to analyse the links and the directionality of significant effects. Overall, among the undesirable DT traits, Psychopathy and Narcissism were both positive and negative predictors of the L2 outcomes, while Machiavellianism unexpectedly emerged solely as a positive predictor. The intricacy of the results underscores the vague nature of the effects, pinpointing the need for more caution while examining negative personality traits in education and the L2 contexts. Based on the results of this study, implications and directions for future research on DT and language learning are suggested.

Learning environment has a great influence on learners’ motivation irrespective of whether the class is conducted physically or through online. As online education is expanding at a fast pace, online educators have a need to understand the learning environment of the students. In this context, the current study contributes to the existing knowledge on the learning environment, by studying what the teachers understand about the learning environment of the students. The study follows a quantitative method. Convenient sampling is done to obtain the samples. The lecturers and students of a pre university college formed the sample. The data collection tool used is the Online Learning Environment Survey (OLES) tool for teachers and students prepared by Curtin University and which has been tested for reliability, validity and consistency. The tool comprised of 8 Likert scales with 32 Likert items. Statistical tools for testing normality and non-parametric test such as Mann-Whitney U-test used to analyse the data obtained through the instrument. It is found that there is significant difference in the preference on online learning environment among teachers and students. The effect size was found out to be 0.39. The learning environment, computer usage had a large effect size of 0.46 compared to other learning environment teacher support, student interaction, personal relevance, authentic learning, student autonomy, equity and asynchronocity.

As brotações originaram-se de minicepas seminais, cultivadas em vasos plásticos de 3,0 L com aberturas na parte inferior com substrato composto por areia, fração fina e fertirrigadas de solução nutritiva em três concentrações: 25, 75 e 100% sendo realizada 6 coletas ao longo do tempo. A produção de miniestacas foi conduzida a partir do delineamento em blocos casualizados com arranjo fatorial (3x6) e parcelas subdivididas no tempo, sendo os fatores constituídos por solução nutritiva (S1 – 100%, S2 – 75%, S3 – 25%) e coleta de brotos (6 coletas), de acordo com a produtividade. A produção de miniestacas por metro quadrado ano (NM) variou significativamente em relação à solução nutritiva e as coletas de brotações e os resultados apresentaram oscilações ao longo das seis coletas. A solução de 100% e a 6ª coleta obtiveram a maior produção de NM. Palavras-chave: minijardim clonal, miniestaquia, propagação vegetativa. PRODUCTIVITY OF MINI STUMPS OF Eucalyptus urophylla S. T. Blake ON DIFFERENT NUTRITIONAL SOLUTIONS AND COLLECTION OF SPROUTS ABSTRACT This work aimed to quantify the production of mini stakes by mini stumps of Eucalyptus urophylla in relation to the collection of sprouts and concentrations of nutritive solution. The sprouts were originated from seminal mini stumps, cultivated in plastic pots capable to store 3.0 L, with openings at the bottom, with substrate composed of sand, thin layer, and fertigated with nutritive solution in three concentrations: 25, 75 and 100%, with the accomplishment of 6 collections over time. The production of mini stakes was conducted from a randomized block design with factorial arrangement (3x6) and plots subdivided in the time, with the factors being formed by nutritive solution (S1 – 100%, S2 – 75%, S3 – 25%) and collection of sprouts (6 collections), according to productivity. The annual production of mini stakes per square meter (NM) has significantly varied in relation to the nutritive solution, and the collections of sprouts and the results have shown oscillations over the six collections. The 100% solution and the 6th collection have obtained the greatest production of NM.

TENDÊNCIA TEMPORAL E FREQUÊNCIA DE PRECIPITAÇÕES MÁXIMAS EM CRUZEIRO DO SUL, ACRE A verificação de tendências temporais em séries históricas e a análise de frequência da ocorrência de eventos de precipitações máximas são importantes para o conhecimento da dinâmica dos processos hidrometeorológicos. Neste contexto, o presente trabalho objetivou verificar tendências em séries de dados observados de precipitações totais mensais máximas anuais em Cruzeiro do Sul, no estado do Acre, registrados na estação 82704 (7°38’S; 72°40’W), operada pelo Instituto Nacional de Meteorologia, além de realizar a análise de frequência, por meio da distribuição de probabilidades de Gumbel para eventos máximos. Os resultados obtidos por meio do teste de Mann-Kendall sugerem leve tendência temporal ascendente, porém, convergem para a não aceitação da hipótese de tendência significativa, ao nível de significância 5%, considerando-se análise compreendida entre os anos de 1971 e 2013. Quanto à análise de frequência, evidenciou-se que a distribuição de Gumbel foi apropriada para representar as precipitações máximas, por meio da aderência obtida pelos testes de Kolmogorov-Smirnov e do Qui-Quadrado, a 5% de probabilidade. Palavras-chave: séries de precipitações máximas, verificação de tendências, distribuição de probabilidades.   ABSTRACT The verification of temporal trends in historical series and the frequency analysis of maximum precipitations events are important for the understanding of the dynamics of the hydro-meteorological processes. In this context, this study aimed at verifying series trends in the observed data from the annual maximum monthly precipitations in Cruzeiro do Sul, Acre State, Brazil, registered at 82704 station (7°38’S; 72°40’W) operated by the National Meteorological Institute, besides performing the frequency analysis through Gumbel probabilistic distribution for the maximum events. The results obtained through Mann-Kendall test suggest a light increasing temporal trend; however, it converges on rejecting the hypothesis of a significant trend, at the significance level of 5%, considering the analysis between 1971 and 2013. Regarding the frequency analysis, it was shown that Gumbel’s distribution was appropriate to represent the maximum precipitation, through the adherence obtained by the Kolmogorov-Smirnov and the Chi-Square tests, to 5% probability. Keywords: maximum precipitation series, trend verification, probability distribution. DOI: http://dx.doi.org/10.14583/2318-7670.v04n02a08

POTENCIAL DE ATAQUE FÚNGICO PARA MADEIRAS NO ESTADO DO MATO GROSSOEste trabalho caracteriza a distribuição temporal e espacial do Potencial de Ataque Fúngico (PAF) para a madeira no Estado do Mato Grosso. Utilizou-se os dados meteorológicos de series temporais de 7 anos (2008-2014) de 30 estações meteorológicas automáticas (EMA’s), da rede de estações do Instituto Nacional de Meteorologia (INMET). Utilizou-se as médias mensais de temperatura do ar e o número de dias com chuva acima de 0,30 mm no mês. Empregou-se a interpolação pelo software Arcgis 10.0, com discretizações de PAF em meses, estações seca e chuvosa e anual. Os resultados apresentaram grande variação de PAF para o Mato Grosso, tendo os maiores e menores índices ocorrido em janeiro e julho. Na estação seca ocorre um baixo potencial de deterioração da madeira por fungos (PAF entre -2,70 à 3,40). Em contrapartida, na estação chuvosa, PAF variou de 16,60 a 25,90, em função da concentração de dias com precipitações acima de 0,30mm. O somatório total anual de PAF variou de 119 a 198, tendo a região norte do Estado os maiores valores por possuir altos índices pluviométricos. Recomenda-se atenção na secagem e armazenamento da madeira na estação chuvosa (outubro a abril) para as regiões Norte, Noroeste, Nordeste e Oeste do estado de Mato Grosso.Palavras-chave: biodeterioração, fungos xilófagos, variáveis ambientais. ABSTRACTThis work characterizes the temporal and spatial distribution of Fungal Attack Potential (FAP) for wood in Mato Grosso state, Brazil. The meteorological data of temporal series of 7 years (2008-2014) were used, from 30 automatic weather stations (AWS ‘s) of the stations network of the National Institute of Meteorology (INMET). The monthly average of air temperature and the number of days with rain over than 0.30 mm the month were used. The interpolation by Arcgis 10.0 software was used, with FAP discretization in months, dry and rainy and anual season. The results showed a great variation of FAP to Mato Grosso, with the highest and lowest rates, occurred in January and July. In the dry season, there is a low potential wood deterioration by the fungus (FAP between -2.70 to 3.40). In contrast, in the rainy season, FAP ranged from 16.60 to 25.90, depending on the concentration of days with precipitations over 0.30 mm. The total annual sum of FAP ranged from 119 to 198, and the north of the state showed the highest values by having high rainfall rates. It is recommended attention on drying and storage of wood in the rainy season (October to April) to the North, Northwest, Northeast and West of Mato Grosso state.Keywords: biodeterioration, wood decay fungus, environmental variables. DOI: http://dx.doi.org/10.14583/2318-7670.v04n03a07
