The study of phase formation in the system CsCl – CoCl2 – H2O at 25 °C was carried out for the first time. The concentration ranges of crystallization and the nature of solubility were determined for five compounds: CsCl, Cs3CoCl5, Cs2CoCl4, CsCoCl3·2H2O, and CoCl2·6H2O. It has been established that the Cs3CoCl5 crystal is incongruently soluble (in a slight excess of CsCl), the Cs2CoCl4 crystal is congruently soluble, and the CsCoCl3·2H2O crystal is incongruently soluble (in a significant excess of CoCl2·6H2O). Single crystals of double cesium-cobalt chlorides were obtained for the first time by the method of isothermal evaporation. The size and quality of the obtained crystals made it possible to indicate the external faceting of the crystals. It has been established that the method of obtaining crystals based on a controlled decrease in the temperature of a saturated solution is not suitable for double cesium-cobalt chlorides due to their weak temperature dependence of solubility. The optical spectra of double cesium-cobalt chloride crystals were studied in the range of 200 – 800 nm. It has been established that the transmission spectra of the Cs3CoCl5 and Cs2CoCl4 crystals are largely close to each other, while the transmission spectrum of the CsCoCl3·2H2O crystal differs from them. Such spectral characteristics are primarily due to the structure of the nearest coordination environment of cobalt atoms in the structures of the studied crystals. In Cs3CoCl5 and Cs2CoCl4 crystals, cobalt atoms are in a tetrahedral chlorine environment ([CoCl4]), while in a CsCoCl3·2H2O crystal they are in an octahedral water–chlorine environment ([CoCl4(H2O)2]).

The thermal stability of a bimetallic wire made of four novel aluminum alloys Al – 0.25 % Zr with different Sc and Hf contents has been investigated. A wire made of pure aluminum A99 was studied as an object of comparison. Alloys were obtained by injection molding in vacuum. Cast samples were subjected to severe plastic deformation and annealing, which ensured the formation of a uniform microstructure and the release of stabilizing Al3(Zr,Sc,Hf) nanoparticles. The wire ∅ 0.26 mm was obtained by joint deformation of an aluminum alloy with a copper shell by rolling in rolls. The effect of 30-minute annealing in the temperature range from 200 to 500 °C on the parameters of the microstructure and physical and mechanical properties (microhardness, strength, plasticity, specific electrical resistivity) of the wire was studied. The wire has high strength and increased thermal stability. After annealing at a temperature of 500 °C, a homogeneous fine-grained structure with a grain size of 3 – 5 µm was formed in the wire, increased hardness and strength of the samples was observed due to the separation of Al3(Zr,Sc,Hf) particles. There is an intense diffusion of copper from the shell into the surface layers of the aluminum alloy, which can lead to embrittlement of the wire.

The paper presents the results of a study of the influence of the concentration and particle size of the filler on the thermomechanical properties of composite materials based on polypropylene and waste from waste processing industry (thermal ash). Three grindings of thermal ash were used with particle sizes: 90 nm, 300 – 500 nm and 1200 – 2000 nm. It has been established that with an increase in the size of thermal ash particles, the deformation curve in the region of the viscous-flow state shifts to the region of high temperatures. As a compatibilizer used functionalized with 5.6 wt. % maleic anhydride polypropylene grade Exxelor PO1020 to improve miscibility and compatibility of non-polar polypropylene with thermal ash particles. It is shown that the introduction of different amounts of the cross-linking agent dicumyl peroxide contributes to a significant change in the pattern of deformation of nanocomposites with temperature. The concentration of dicumyl peroxide was varied within 0.25 – 2.0 wt. %. Peroxide crosslinking using 0.25 – 0.5 wt. % dicumyl peroxide contributed to the appearance of a region of highly elastic deformation on composites with 5.0 and 40 wt. % thermal ash. With an increase in the concentration of dicumyl peroxide over 0.5 wt. % vitrification of nanocomposites was observed. In this state, the samples are completely crosslinked and pass into the infusible state. Such an infusible state is highly undesirable since it is not possible to process them by injection molding and extrusion.

The conditions for the preparation of a compound with an eulithine crystal structure (ESS) during the crystallization of a stoichiometric melt in the Bi2O3 – GeO2 system by casting have been investigated. The initial components (Bi2O3 and GeO2) were placed in a platinum crucible and heated to a temperature in zone C at a rate of ~ 20 °C/min, with holding under isothermal conditions for 1 h. Then, the melt was poured from the crucible onto a heated platinum plate. The macrostructure of the surface of the crystallized samples was observed using a Stemi 2000 stereoscope (Carl Zeiss), the microstructure was observed using a Carl Zeiss Axio Observer A1m optical microscope on microsections. X-ray phase analysis (XRD) of the powder was performed on a Shimadzu XRD 6000 diffractometer (Cu Kα radiation). Atomic absorption spectrometry was carried out on a SOLAAR M device. For the first time, the possibility of obtaining Bi4Ge3O12 with the eulithine crystal structure (ESS) by fusing a stoichiometric mixture of initial oxides and subsequent cooling of the melt by casting was experimentally shown. It is shown that when using this method, it is possible not only to achieve record rates of synthesis, but also to reduce the content of platinum (which is a harmful impurity) in the resulting material by 2 times.

Falls from height (FFH) isa significant threat to the construction environment and are the leading cause of serious and fatal injuries for construction workers. Working at a height increases the likelihood of being involved in a fall from a height accident. Since the construction industry is carried out in risky environments, it isexperiencing accidents at different severity rates, some causing minor injuries, some causing severe injuries, and some resulting in fatalities. Most fall from height accidents will affect the individual, such as permanent disabilities, worker fatalities,and affect the psychology of workers. This research objective is to find the cause and effect of fall from height accidents and mitigation measures in Malaysia. The findings of this research indicate that individual attitude is the main contributing factor to falls from height accidents, with the top five highest Relative Important Index (RII) ranking. The main causes of fall from height accidents are individual attitudes, which is workers' negligence toward safety rules with RII=0.901. Then, the respondent strongly agrees that the humanitarian categories of injuries or permanent disabilities with RII=0.899 are the adverse effects of fall from height accidents. After that, the utmost possible mitigation measures with the highest RII ranking are in the health protection categories, which forbid working at height if alcohol or drugs have been detected on workers with RII=0.930. Lastly, the identified causes of FFH accidents were selected to be used in the Loughborough ConAC Model. The establishment of the model is important to clearly represent the FFH accident and ultimately to reduce the fall from height accidents in Malaysia.

Published: November 2022

Vibration issues of floor areas in relation to human comfort perception in an open working space are very common. This paper discusses the results of a human comfort assessment before and after strengthening of a a post-tensioned reinforced concrete flooring structure. All floors experience structural vibration, which arises from various sources inside and outside of the building. This paper investigated the vibration issue of a problematic flooring slab area on Level 3 of a four storey building, which vibrations induced by people walking through the working station area. Two types of tests were conducted, namely a (1) shaker test and a (2) walking test. Accelerometers were attached to the floor according tothe sensor points and recorded all acceleration responses on the floor system. The highly sensitive KS 48C accelerometer was used in this study. The accelerometers were placed at the same locations for both shaker and walking tests. The floor slab which was initially reported as problematic structure on Level 3 was found that its peak acceleration exceeded the recommended human comfort limitation. A passive vibration isolation technique was used in order to tackle the vibration issue. A laminated elastomeric bearing was chosen as one of the methods in passive vibration isolation. The natural frequency for both results before and after strengthening remained as low-frequency floor classes. However, peak acceleration excitation was reduced after the strengthening work was completed.

The Malaysian construction industry contributes more than one-third of fatalities out of all industries and further proves that safety performance in the construction industry lags behind most other industries. One of the causes is due to the lack integration of technological system and people in safety and health (OSH). This study suggests that one of the ways to avoid accidents at construction site is through an effective OSH management planning tool, with proper management of the interaction between technological systems and people. As an initial step towards the development of the tool, this study aims to investigate the contractors’ compliance with OSH legislation in the Malaysian construction industry. It also attains construction stakeholder’s perceptions of the current situation and intervention to improve OSH performance in the construction industry by providing information or creating a system that can provide information according to the acts and regulations. The information was collected through interviewing selected respondents from several organizations and enforcers in construction industry. The results revealed that the majority of construction organizations followed the OSH requirements, though they did not comprehensively follow them. Lack of knowledge about OSH was also acknowledged by the organizations, even though they were aware about the OSH requirements. The findings also revealed that there is no available tool that can provide information about legislation on OSH requirements which can facilitate the construction teams effectively and lead to prevent an accident happens at the construction site.Therefore, it is essential to improve the safety performances including provide the guidelines of the OSH according to the acts and requirements and enhancing the management in improving the safety at construction sites.

Published: November 2022

This study aims to determine the future expectation of university students studying in the field of sports sciences and to examine how it affects their attitudes toward brain migration. The "Brain Migration Scale", developed by Öncü et al. (2018), was used to evaluate the attitude toward brain migration, and the "Future Expectation Scale", developed by Şimşek (2012), was used to measure the future expectation of the students. The approval of the ethics committee was obtained for the study. This program data was collected by applying Sports in different universities with Sports Management program in Istanbul. 299 students responded to the survey questions via the google form link. The data were analyzed with SPSS 25.0 package program. It was determined that the data showed normal distribution. Multiple regression analysis and Pearson Product-Moment correlation tests were applied to the research data. According to the results of the research, it was found that there are significant and positive relationships between the participants' attitudes towards brain migration and their personal and professional future expectations, educational, economic, and total future expectations. On the other hand, it has been determined that there is no significant relationship between students' attitudes toward brain migration and their expectations for a social future. When looking at the impact force, it was seen that students' economic future expectation was more effective in predicting the attitude toward brain migration than their future expectation of education. In this context, it is important to ensure economic stability and improve working conditions in our country.

Published: November 2022

The International Olympic Committee, as the main sports organization in the world, has several criteria for handing over the Olympic Games to the host city. One of the most critical concerns in hosting sports events is paying attention to environmental aspects and sustainable development. In fact, the applicant cities must have practical environmental goals and action plans. Basically, the host cities have made significant initiatives to improve the environment in previous Olympic Games, but according to the data and studies, this major sporting event has also had detrimental consequences on the environment. Given the importance of sustainable development and environmental protection, this study examines the negative impacts of mega-sporting events on the environment. Therefore data were collected from qualitative interviews, library studies, and previous research. Fifteen experts in the sports and environment field were selected as a sample by snowball distribution method and the interview steps were performed until the theoretical saturation was reached (20-40 min in 3 sessions). After summarizing and analyzing the data, it was found that the negative environmental externalities mainly occur in the Infrastructure and construction, Transportation, and Waste management domains. Emphasizing the findings, the result of this research can be used to identify key local environmental concerns, and pressure points and provide part of the solution for organizers seeking to use their time and resources as efficiently as possible in achieving environmental goals.

Cancelaram a velhice
Authors: Duque Marilia
Published: November 2022

Este artigo propõe um paralelo entre a Cultura do Cancelamento e os mecanismos de comparação social, vigilância e exclusão mapeados durante etnografia conduzida com idosos de um bairro de classe média em São Paulo. Observou-se que as redes sociais viabilizam a performance do idoso ativo, saudável e produtivo em conformidade com a autonomia construída como moralmente desejável e condicionante do status de Terceira Idade. Essa performance funciona como lastro e possibilita o ocultamento de declínios do corpo e sinais de dependências e ociosidade, cujo flagrante promoveria o cancelamento desse status e a reclassificação do idoso na Quarta Idade.

The current study explored the understandings and experiences of Asian international students (AISs) in terms of mental health, disclosure and help-seeking within higher education (HE) in Scotland, UK. A qualitative study using individual semi-structured interviews with AISs (n=20) was used and an inductive thematic approach to analysis was conducted. Three major themes were developed: (1) Negative beliefs, stigma and fear of judgment impacting on understandings and disclosure of mental health issues (mental health as taboo and collective pressures to succeed), (2) Adaptation and acculturation difficulties (lack of sense of belonging), and (3) Barriers in communication, social disconnection and loneliness. Supporting AISs involves challenging negative judgements surrounding mental health, increasing mental health literacy and addressing barriers in overcoming adaptation, acculturation and communication difficulties that may inhibit disclosure and help-seeking behaviour. The need for culturally sensitive mental health practitioners and awareness of diverse understandings of mental health issues is essential.
Competing theories of eyewitness identification
Authors: McCormick Kym Michelle
Published: November 2022

Psychological researchers have put forward several theories of eyewitness identification behavior, each of which offers differing hypotheses relating to eyewitness memory and identification task difficulty. While earlier (informal) models of eyewitness identification behavior provide a sense of understanding in ways that are both intuitive and accessible, recently introduced formal (mathematical) models provide researchers with improved precision and the potential for strengthening theory via hypothesis testing. This paper describes two distinct formal model classes within the eyewitness identification theory set—continuous models and discrete-state models—and how each model set aligns with the existing informal models. I suggest that the theoretical conflict between these competing model sets has created an ethical dilemma between either viewing eyewitnesses as ‘fallible observers’ who act in good faith, or as ‘poor decision makers’ who cannot be trusted to provide evidence of any probative value. This a dilemma that must be resolved if we are to gain a better understanding of eyewitness identification processes.
How Loneliness Undermines Close Relationships and Persists Over Time: The Role of Perceived Regard and Care
Authors: Lemay Edward , Cutri Jennifer , Teneva Nadya
Published: November 2022

Although loneliness has been associated with negative perceptions of social life in past research, little is known about the implications of loneliness for interpersonal perception within close relationships. The current research includes three studies (total N = 1,197) suggesting that loneliness is associated with a negative bias in perceiving relationship partners’ regard and care, and that this bias partially accounts for the effects of loneliness on lower relationship quality and problematic interpersonal behaviors. Loneliness was associated with perceiving family members (Study 1), friends (Studies 1 and 2), and romantic partners (Studies 1-3) as less admiring and caring, and these effects were independent of a variety of accuracy benchmarks, including partners’ self-reports (Studies 1-3), reports from informants (Study 2), and objective observers’ assessments of partners’ responsive behavior (Study 3). Loneliness also predicted changes in perceptions of partners’ regard over time (Study 3), and indirectly predicted lower relationship satisfaction, commitment, self-disclosure, and support provision through negative perceptions of relationship partners’ regard and care (Studies 1-3). Studies 2 and 3 replicated these results in terms of day-to-day experiences (total daily observations = 16,064). The negative perceptions of partners’ regard and care associated with loneliness predicted subsequent loneliness (Studies 2-3). Loneliness effects were statistically independent of self-esteem and attachment insecurity in all studies. Taken together, these findings suggest that, due to negative biases in perceiving relationship partners’ regard and care, loneliness may compromise the quality of close relationships, motivate interpersonally problematic behaviors, and become persistent. Implications are discussed.
Sounds and speech: Individual differences in unfamiliar voice recognition
Authors: Sunilkumar Dolly , Kelly Steve , Stevenage Sarah V , Rankine Dillon , Robertson David J
Published: November 2022

In several applied contexts (e.g., earwitness testimony), the accurate recognition of unfamiliar voices can be a critical part of the person identification process. However, recognising unfamiliar voices is prone to error. While such errors could be reduced by testing the proficiency of listeners, the established tests of unfamiliar voice matching (BVMT) and memory (GVMT) may be limited by their choice of stimuli (i.e., vowel-sounds) and their design (i.e., using identical sounds at learning and test; GVMT). Here, we examine whether these sound-based tests are predictive of performance on more naturalistic speech-based tasks, and whether performance is consistent across task-domain (matching/memory) and task-modality (voices/faces). The findings show that while the BVMT was a robust predictor of speech-based voice matching, this was not the case for the GVMT and speech-based voice memory. In addition, we provide evidence for a potential common person recognition factor ‘p’. The theoretical and applied implications are discussed.
Comments on the use of mathematical models in eyewitness identification research
Authors: McCormick Kym Michelle
Published: November 2022

Mathematical models of eyewitness identification provide frameworks within which researchers may be supported in their attempts to improve the measurement of identification outcome variables, access the full richness of eyewitness memory data, including metacognitive information, and develop stronger theories of eyewitness memory. This paper provides an overview of the ways in which signal detection theory (SDT) models of eyewitness identification provide measurement tools, such as ROC curve analysis, while also providing a framework for the development of eyewitness identification behavior theory through the exploration of model constraints, such as zero correlation between stimuli values, filler equivalence, and fixed criterion. Consideration of future research and the dissemination and uptake of new analytical tools is provided.
EVALUATING THE PSYCHOMETRIC PROPERTIES OF THE FIVE-FACET MINDFULNESS QUESTIONNAIRE: AN ITEM RESPONSE THEORY ANALYSIS
Authors: Bowman Angela S. , Kim Jwa , Crooks Catherine , Fuller Dana K.
Published: November 2022

Mindfulness has been extensively studied and a large body of research delineates the relationship between mindfulness and well-being. The Five-Facet Mindfulness Questionnaire (FFMQ) measures the dominant facets of mindfulness. The FFMQ has been shown to have solid classical test properties, but often the factor structure does not hold up under factor analysis, thus an item analysis was conducted. Data were analyzed from 644 individuals. Reliability of each facet of the FFMQ (observing, describing, acting with awareness, non-judging of inner experiences, and non-reactivity to inner experiences) were found to have mediocre to good classical test properties. Under Samejima’s graded response model, the pattern of results revealed poor discrimination and little information provided at all levels of the trait for each item of the observing and non-reactivity to inner experiences scales. However, the remaining scales appeared to discriminate well and provided adequate information at a range the trait. Limitations and future directions are discussed.
