The hard magnetic (Sm,Zr)(Co,Fe,Cu)z alloys intended for the application as powder filler in bonded magnets are considered. The microstructure and intrinsic coercive force of the Sm0.87Zr0.13(Co0.702Cu0.088Fe0.210)6.7, Sm0.81Zr0.19(Co0.702Cu0.088Fe0.210)6.3, and Sm0.85Zr0.15(Co0.690Cu0.070Fe0.240)6.8 alloys, the structural and magnetic states of which were prepared at different aging temperatures and cooling rates, are studied. The formation of the high coercive force and adequate squareness of the magnetic hysteresis loop for alloy powders under study was observed at grain and subgrain sizes of the 2:17 phase of 10 – 20 μm. It is shown that the anisotropic powders of the Sm0.87Zr0.13(Co0.702Cu0.088Fe0.210)6,7 alloy can be prepared for manufacturing bonded magnets with a coercive force of 14 – 20 kOe and higher, which are intended for the application in electric machines.

Influence of surface electron-beam processing on character of fatigue cracks propagation and crack growth rates under cyclic tension in a mode of low-cycle loading of TiNi samples before and after irradiation by low-energy high-current electron beam (LEHCEB) is studied in the work. Correlation between stages of fatigue cracks propagation and formation of plastic zones on surfaces of failure in TiNi samples before and after LEHCEB treatments is established. The LEHCEB treatment of specimen surfaces was carried out at the electron-beam installation “RITM-SP” with the electron beam parameters: energy density ES = 3.7 J/cm2, pulse duration τ = 2.5 μs, number of pulses n = 5. Differences in the stages of propagation of main fatigue cracks during cyclic stretching of TiNi samples before and after LEHCEB have been revealed. Preferential mechanisms of quasistatic and fatigue fracture at different stages of crack propagation are determined. It is shown that LEHCEB treatment leads to a shift of fatigue fracture initiation and the beginning of all stages by ∆N ≥ 3000, increasing the cyclic durability of the specimens by ~ 1.5 times. The greatest influence of surface modification is shown on Stage I of fatigue crack propagation. The lower rate of fatigue crack propagation at this stage in irradiated specimens leads to an increase in its duration as compared to unirradiated specimens. It is concluded that to effectively increase the fatigue life of TiNi specimens by means of LEHCEB treatments it is necessary to create conditions for increasing the number of cycles before the Stage I initiation and maximizing the duration of this stage.

Porous sinters of solid solutions were obtained from the elements by the SHS method and then crushed in a ball mill to a fraction of d50 < 10 µm. Single-phase (Hf1 – хTах)B2 solid solutions with a wide range of compositions were obtained by a hot pressing. Detailed investigations of structure and properties were carried out. The plotted lattice parameters vs. solid solution stoichiometry diagrams confirmed the Vegard’s law. SEM, TEM, and EDX structural analysis demonstrated the existence of a HfВ2 – TaB2 single-phase solution region. The structure of samples (lamellas) of (Hf0.8Ta0.2)B2 and (Hf0.6Ta0.4)B2 solid solutions was analyzed by TEM. It has been established that with an increase in the content of tantalum, the size of subgrains decreases to 0.2 – 1 µm. This correlates with the CSR size determined by the X-ray diffraction method. Studies of mechanical properties of single-phase solid solutions have shown that (Hf0.8Ta0.2)B2 and (Hf0.6Ta0.4)B2 possessed extremely high hardness of 63–70 GPa and elastic modulus of 550 – 587 GPa. Electrical resistance dependence on temperature was investigated, values of heat capacity, thermal diffusivity and thermal conductivity coefficients were determined in a wide range of (Hf 1 – xTax)B2 solid solution compositions.

This paper presents the results of research on the development of technology for plastic deformation of polymer blanks based on polytetrafluoroethylene (PTFE) and carbon fibers of the UVIS-AK-P brand in order to increase their strength and creep resistance. The dependence of the physico-mechanical and tribotechnical characteristics of the obtained composites is investigated and compared with a composite of the same composition, but obtained using a previously developed technology. It is established that the use of plastic deformation technology for the properties of PCM based on PTFE and carbon fibers of the brand UVIS-AK-P is an effective solution for obtaining high-strength, wear-resistant composites, characterized by increased resistance to tensile loads. The developed composites obtained using plastic deformation are characterized by 3 times increased tensile strength and 22 – 29 times reduced creep compared to the original PTFE obtained by standard technology. Structural studies of the technology of plastic deformation of polymer blanks have shown that this technology leads to the orientation of the carbon fiber (CF) in the direction of the flow of the material and a change in the spiral conformation of macromolecules with a transition to a more stable conformation, which favorably affects its operational properties. The use of this method will make it possible to obtain high-strength polymer materials with increased resistance to deformation, promising for use for loading schemes with high tensile loads.

The objective of this research is to study urban expansion surrounding archaeological attractions by Normalized Difference Built-up Index (NDBI) technique at ancient civilization site of Haripunjaya Kingdom in Mueang Lamphun District, Lamphun Province, Thailand. From the survey area on October 18-20, 2022, the data was collected on important ancient sites that still appear traces around the city of Lamphun. The study found that there are a total of 13 archaeological sites, each of which is classified into 3 categories: 8 Ancient Religious sites, 4 Acient City Wall sites, and 1 Historical site. Then, surveys of urban and built-up land cover found that within the past 20 years, light urban and built-up land, urban areas and buildings with sparse density increased by 534.45%, or about 5 times, appearing around the old city in Nai Mueang sub-district and the area where the main road passes in a corridor pattern. In addition, the medium urban and built-up land area has also grown more than three times. It can be seen that urban expansion direction in the northern and central of the study area is most located in the 5 sub-district areas: Makhuea Chae, Ban Klang, Wiang Yong, Pa Sak, and Nai Mueang. The NDBI analysis revealed that the archaeological attractions that were most affected by urbanization were the Victory Shrine Pagoda. At present, it has become a historical site in the middle of the community area. It is located in the middle of the shopping mall parking lot, and there are buildings surrounding it, causing the archaeological site to be invaded and damaged greatly. The results of this study can be used to effectively manage cultural tourism planning, especially in the ancient civilization sites in Mueang Lamphun District, to be sustainable in the future.
A systematic review on the effectiveness of children’s interactive reading applications for promoting their emergent literacy in the multimedia context
Authors: Chuang Chen , Jamiat Nurullizam
Published: February 2023

Emergent literacy is the term used to describe the reading and writing experiences of young children before they learn to write and read conventionally, and it is important for the construction of children’s early reading skills and the enhancement of their later reading performance. The systematic review was conducted to examine the effectiveness of children’s interactive reading apps in promoting emergent literacy for children between the ages of three and eight over the last decade (2013-2022). A total of 50 studies were included in this review, and it can be concluded that multimedia features (e.g., a dictionary, background music, and animated pictures) in children’s interactive reading apps are effective for enhancing emergent literacy. Conversely, interactive functions (such as games and hotspots) may distract children’s attention, leading to poor reading performances. This review also demonstrated the positive effects of children’s interactive reading apps on improving their learning outcomes and behavior. In addition, the results indicated that well-designed apps could promote children’s emerging literacy skills. However, more in-depth studies will be required in the future to provide designers with a well-defined guideline for designing reading apps for children.

This study aims to find out how these three components are related and influence each other. This study specifically analyzes the effect of teacher certification and teacher motivation on teacher performance in several Islamic elementary schools in South Jakarta. This study uses a regression analysis method with a quantitative approach. The quantitative method was chosen to be used in this study because the specifications of this design were systematic, planned, and clearly structured from the start of the creation of the research design. This research will also take a descriptive approach in order to adequately describe the research object or research results. The population in this study are teachers who have received a teacher certification allowance for at least five years and have had teaching experience for approximately ten years. Based on research data and discussion regarding the effect of teacher certification and teacher work motivation on teacher performance at Madrasah Ibtidaiyah as KKMI Kebayoran Lama, the following conclusions can be drawn: First, teacher certification has a partially positive effect on teacher performance. This is indicated by the value of the X1 regression coefficient of 1,401, which states that every 2 percent increase in teacher certification will increase teacher performance by 1,401 percent. The probability value is less than 5%, namely 0.000 < 0.05 indicating that teacher certification has a positive effect on teacher performance. Second, teacher work motivation partially has a positive effect on teacher performance.

Published: February 2023

Currently, Instagram is widely used as a media campaign for nationalism and feminism. There are several feminists and nationalist figures in Indonesia who also actively use Instagram social media, namely Retno Marsudi and Susi Pudjiastuti. The purpose of this research is to analyze the effectiveness of Instagram as a media campaign for nationalism and feminism among teenagers in Batam City. This research is an interpretative qualitative research with Roland Barthes's semiotic analysis. Primary data sources were obtained from Instagram posts in the form of image snippets and image elements, captions and netizens, and comments contained in these Instagram posts. While secondary data obtained was from books, journals (online), and articles (online). Data collection in this study was obtained by using documentation techniques. The collected data were then analyzed by interpreting the two stages of sign from Roland Barthes' semiotic theory. The results of the study show that feminism in Indonesia is considered very minimal when compared to nationalism. There is a gap between women and men. This is due to the strong culture and beliefs of the Indonesian people who think that women should not exceed men in various aspects.

Does Twitter data mirror the European North-South family ties divide? A comparative analysis of tweets about family.
Authors: Gil-Clavel Soﬁa , Mulder Clara H.
Published: February 2023

Previous research on the relationship between geographical distance and the frequency of contact between family members has shown that the strength of family ties differs between Northern and Southern Europe. However, little is known about how family ties are reflected in peoples’ conversations on social media, despite research showing the relevance of social media data for understanding users’ daily expressions of emotions and thoughts based on their immediate experiences. This work investigates the question of whether Twitter use patterns in Europe mirror the North-South divide in the strength of family ties by analyzing potential differences in family-related tweets between users in Northern and Southern European countries. This study relies on a longitudinal database derived from Twitter collected between January 2012 and December 2016. We perform a comparative analysis of Southern and Northern European users’ tweets using Bayesian generalized multilevel models together with the Linguistic Inquiry and Word Count software. We analyze the association between regional differences in the strength of family ties and patterns of tweeting about family. Results show that the North-South divide is reflected in the frequency of tweets that are about family; that refer to family in the past versus in the present tense; and that are about close versus extended family.

Sievert (2023): The Limited Impact of Reference Groups’ Symbolic Gender Representation on Willingness to Coproduce
Authors: Sievert Martin
Published: February 2023

Previous literature presents a strong rationale for the positive impact of symbolic representation in coproduction contexts. However, empirical studies yield inconclusive findings indicating that meaningful effects are limited if citizens face high levels of uncertainty. This article combines symbolic representation with signaling theory, suggesting that the representativeness of central reference groups might reduce uncertainty. The theoretical framework suggests that the representation of supervisors and existing coproducers might positively affect citizens’ willingness to coproduce. Contrary to the theoretical expectations, the empirical results from two preregistered factorial survey experiments (n = 2,979), situated in prisoner rehabilitation and refugee integration, indicate that the symbolic gender representation of these reference groups has a limited impact. Only a balanced representation of coproducers exhibits a positive treatment effect on citizens’ willingness to coproduce. The results oppose central arguments in the representative bureaucracy literature. At least for gender categories, symbolic representation is less important than expected.

Willingness to experience unpleasant thoughts, emotions, and bodily sensations at admission does not predict treatment outcome in inpatients with obsessive–compulsive disorder
Authors: Zisler Eva , Meule Adrian , Koch Stefan , Voderholzer Ulrich
Published: February 2023

Background: Willingness to experience unpleasant thoughts, emotions, and bodily sensations (WTE) has been found to predict treatment outcome in patients with obsessive–compulsive disorder (OCD). Yet, these findings are limited to few studies. Methods: We examined whether WTE at admission predicted treatment outcome in a sample of 324 inpatients with OCD who received a multimodal treatment that included cognitive-behavioral therapy with exposure and response prevention sessions. Results: Obsessive–compulsive symptoms (based on OCD-specific self-report questionnaires) decreased and global functioning (based on therapist ratings) increased from admission to discharge. In contrast to previous findings, however, WTE did not predict treatment outcome. Conclusions: On the one hand, these results indicate that higher WTE at the beginning of inpatient treatment does not facilitate improvements in obsessive–compulsive symptoms from admission to discharge. On the other hand, they also indicate that lower WTE at the beginning of inpatient treatment does not adversely affect treatment outcome, that is, even patients who indicate that they are unwilling to face the negative experiences associated with exposure and response prevention can still achieve considerable symptom reductions. While the current findings suggest that WTE at the beginning of treatment only plays a minor role at most in treating OCD, future studies may examine session-to-session changes in WTE and obsessive–compulsive symptoms during treatment which may reveal a dynamic interplay as therapy progresses.
Mixed-Effects Regression Weights for Advice Taking and Related Phenomena of Information Sampling and Utilization
Authors: Rebholz Tobias R. , Biella Marco , Hütter Mandy
Published: February 2023

Objective: Advice taking and related research is dominated by deterministic weighting indices, specifically ratio-of-differences-based formulas for investigating informational influence. Their arithmetic is intuitively simple, but they pose several measurement problems and restrict research to a particular paradigmatic approach. As a solution, we propose to specify how strongly peoples’ judgments are influenced by externally provided evidence by fitting corresponding mixed-effects regression models. Method: Our approach explicitly distinguishes between endogenous components, such as updated beliefs, and exogenous components, such as independent initial judgments and advice. Crucially, mixed-effects regression coefficients of various exogenous sources of information also reflect individual weighting, but are based on a conceptually consistent representation of the endogenous judgment process. The formal derivation of the proposed weighting measures is accompanied by a detailed elaboration on their most important technical and statistical subtleties. Results: We use this modeling approach to revisit empirical findings from several paradigms investigating algorithm aversion, sequential collaboration, and advice taking. In summary, we replicate and extend the original finding of algorithm appreciation, and initially demonstrate a lack of evidence for both systematic order effects in sequential collaboration as well as differential weighting of multiple pieces of advice. Conclusions: In addition to opening new avenues for innovative research, appropriate modeling of information sampling and utilization has the potential to increase the reproducibility and replicability of behavioral science. Furthermore, the proposed method is relevant beyond advice taking, as mixed-effects regression weights can also inform research on related cognitive phenomena such as multidimensional belief updating, anchoring effects, hindsight bias, or attitude change.
Pay Justice and Pay Satisfaction: The Influence of Reciprocity, Social Comparisons, and Standard of Living
Authors: Adriaans Jule , Sauer Carsten , Moya Cristóbal
Published: February 2023

This study compares two pay evaluations: pay justice and pay satisfaction. Conceptually, pay justice entails a moral assessment and is more specific to work, whereas pay satisfaction is a broader attitude that includes non-work-related factors. We analyzed German employee data and found overall similarity in determinants but differences in proximity to work contexts. Pay satisfaction was more strongly associated with private pay comparisons and standard of living, whereas pay justice was more strongly associated with reciprocity in the employer-employee relationship through working hours, and comparisons at work. The results therefore suggest that employers can influence pay justice more easily than pay satisfaction by means of addressing imbalances in the employer-employee exchange and within organizational pay structures.

Published: February 2023

Объект: Ипотечное кредитование и строительная отрасль РК. Предмет исследования: выявление особенностей ипотечного кредитования и его влияния на развитие строительной отрасли в период пандемии. Цель исследования — установление рисков ипотечного кредитования на основе проведенного анализа и выявленных тенденций строительной отрасли в периоды до начала пандемии и после.Методы: В исследовании были использованы экономико-статистический метод, рассчитаны относительные показатели, применен анализ, дедукция и метод визуализации данных исследования.Результаты: Жилищное строительство — единственная отрасль, которая в период пандемии пострадала меньше всего. Сохраненные объемы развития строительной отрасли способствовали наряду с другими факторами значительному росту ипотечного кредитования. Следует отметить, что, несмотря на реализованные карантинные меры, увеличивалось количество безработных. В работе проведен литературный обзор актуальных исследований по данной проблематике, рассмотрены причины быстрого роста отрасли в период пандемии, исследована динамика показателей, определены риски возникновения ипотечного пузыря.Выводы: Инвестиции в строительство увеличиваются с каждым годом, предложение на рынке растет, спрос на недвижимость не падает. Проанализировав индексы реальных доходов, цен в строительстве, а также средней стоимости 1 кв м нового жилья, можно прийти к выводу, что рост цен на недвижимость вызван искусственно, рынок подстроился под высокие цены. Параллельно развитию строительного бизнеса и ипотечных программ наблюдается значительное снижение уровня платежеспособности населения, вследствие снижения темпов экономического роста национальной экономики на фоне введенных карантинных мер, что может привести к образованию «ипотечного пузыря».

Methylprednisolone (MP) to treat acute traumatic spinal cord injury (ATSCI) remains controversial since the release of the second National Acute Spinal Cord Injury Study (NASCIS2) in 1990. As two historical studies, NASCIS2 and Sygen in ATSCI, used identical MP dosages, it was possible to construct a new case-level pooled ATSCI data set satisfying contemporary criteria and able to clarify the effect of MP.

METHODS

The new pooled data set was first modernized by excluding patients with injury levels caudal to T10, lower-extremity American Spinal Injury Association (ASIA) motor scores (LEMSs) ≥ 46, Glasgow Coma Scale scores ≤ 11, and age < 15 or > 75 years, and then standardized to the ASIA grading and scoring format. A new updated NASCIS2 data set from this pooled data set contained 31.6% fewer patients than the 1990 NASCIS2 data set.

RESULTS

In the new pooled data set, recovery of LEMSs from baseline to 26 weeks, the primary outcome variable, was separated statistically into five different injury severity cohorts (p < 0.0001). The severity cohorts contained groups with severe floor (62.9%) and ceiling (10.7%) effects, which do not contribute to drug effects. The new NASCIS2 data set duplicated the p value for MP versus placebo in the sub-subgroup analysis of MP initiated ≤ 8 hours (the subgroup) and recovery of motor function on only the right side of the body (a further subgroup within the ≤ 8-hour subgroup), presented as the positive MP effect in the original NASCIS2 reporting. However, current statistical interpretation considers results seen only in post hoc sub-subgroups, without multi-test corrections, to be random effects without clinical significance. The combined case-level pooled data set from the NASCIS2 and Sygen studies increased the MP group from 106 to 431 patients, creating a new MP combined group. This new data set served as a surrogate for a contemporary MP study and found that administration of MP did not enhance ASIA motor score improvement in the lower extremities at 26 weeks. Secondary analysis of descending ASIA motor and sensory cervical neurological levels in cervical ATSCI patients at 26 weeks also found no MP drug effect.

CONCLUSIONS

Analysis of both the new updated NASCIS2 data set and the new case-matched pooled data set from two historical ATSCI studies revealed that administration of MP after spinal cord injury did not demonstrate any enhancement in neurological recovery at 26 weeks. The results of this analysis warrant review by clinical guideline groups.
