The article describes the importance of the development of the emotional sphere of modern preschool children from full versus incomplete families. Various points of view on this problem are considered. In order to identify the differences in the emotional sphere of modern preschool children from full and incomplete families, diagnostic methods necessary and significant for solving the tasks of our study were selected; the volume of the general aggregate sample determined, and independent samples of children as well as parents from either full or incomplete families were determined. The following diagnostic methods were chosen: the method of diagnosing the emotional sphere of the child (Lyudmila Strelkova), the projective game "Post office" (a modification of the test of Elwyn James Anthony and Eva Bene), methods of studying the emotional state (E.T. Dorofeyeva). So that we could determine the differences in the emotional sphere of preschool children from full and incomplete families, the method of mathematical statistics was used – the parametric Student's t-test calculated using IBM® SPSS® Statistics software platform. The presented results indicate lack of differences in the emotional sphere of modern preschool children from full and incomplete families, which is explained by the peculiarities of development of each of the children independently on the family composition. It is revealed that facial expressions and pantomimic are an expressive emotional component of psychophysiological nature. The verbalisation of the emotional state’s development features at various stages of preschool age is due to the pedagogic conditions of learning in the process of speech development; the graphic representation of emotions in older preschool children depends on the emotional experience, emotional activity of the particular child; unconsciousness of behaviour and natural sensitivity of children at the stage of older preschool age does take place.

The TPH-in-soil of three functional zones (industrial, residential, agro-residential) of Khabarovsk have been studied. Areas of acceptable, low, moderately hazardous, moderate, high and very high pollution levels have been identified. It has been found that the TPH-in-soil of different urban functional areas differs significantly. For statistical processing of experimental data, the Boxplots method ("box-and-whiskers diagram") has been used. It has been proposed to switch to the median value of the aggregate sample of the TPH-in-soil in residential and agro-residential areas as the baseline data.

A simple screening test was proposed in order to test coarse aggregates for their potential to cause damage when used in concrete due to the oxidation of sulphide phases. The test involves submerging an aggregate sample in an oxidizing agent and measuring the mass loss. Samples with no known oxidizable sulphides showed a mass loss of <1.0% after one week of testing at room temperature. Samples of oxidizable sulphides showed a mass loss higher than 3.5% and changes in the colour of the test solution. It is proposed that aggregates which achieve a mass loss of less than 0.50% and no colour change in the test solution be accepted.

AbstractWe investigated the significance of an economic crisis for organizations’ ethical behavior, employees’ unethical behavior, and association. To capture the effect of the “2008’ World economic crisis,” we compared the behaviors of organizations and employees’ unethical behavior during a crisis with their behavior in more favorable circumstances before and after the crisis. We used structural equation modeling to analyze answers collected from 2024 employees in Slovenian organizations between 2006 and 2016. The results showed significant growth of organizational engagement in ethical behavior, despite the crisis in the middle of the observed period. The employees’ unethical behavior was significantly less acceptable in crisis compared to before the crisis, while after the crisis, its acceptability increased again, despite not significant. The aggregate sample revealed a significantly negative influence of employee’s unethical behavior on organizations’ ethical behavior that was not significantly different across the considered periods. The research suggests the need to manage the organization’s ethical behavior in times of economic downturn, like in the present COVID 19. Additionally, managers need to devote more attention to prevent employees’ unethical behavior and its influence on organizations’ ethical behavior.

The study has been conducted in the adjoining regions of West Bengal and Bangladesh (erstwhile East Bengal) among various respondent groups. Both the regions have been archetypally known to share multiple cultural commonalities. Notwithstanding, there exists divergences in the culture, which have been tested using Hofstede's Cultural Dimensions Framework. Further, the study investigates whether there exist any divergences in how the personalities of the two smart phone brands, namely, Samsung and Xiaomi, are perceived in the two regions. An aggregate sample of 295 and 287 respondents have been selected conveniently from West Bengal, India and Bangladesh, respectively. The current study primarily aims to probe into the cultural dissimilarities between the two contiguous regions of West Bengal (in India) and Bangladesh. Subsequently, the study investigates the probable impact of such cross-cultural dissimilarities on consumers' perception concerning the personality of select smart phone brands, specifically Samsung and Xiaomi. The study provides good empirical insight into the fact that despite the uniform positioning of the two smart phone brands in the two West Bengal and Bangladesh regions, their personality traits are perceived differently by consumers dwelling in these cultures. The analysis yields that respondents from West Bengal and Bangladesh demonstrated notable congruencies in perceiving Xiaomi as a 'responsible' and ''aggressive' brand. However, Samsung is perceived as an 'aggressive' brand in Bangladesh and 'stable' in West Bengal. The perceptual deviations of the smart phone brands' personalities exist due to the cultural divergences between the two regions. The current study is unique in that it offers a new-fangled perspective to looking at cross-cultural research by comparing politico-administrative units instead of countries at large. Yet, it is bound by imperfections, such as limited sample size, making it difficult to make more detailed comments on individuals' perceptions towards the brand personality dimensions of smart phones. Although adequate care has been taken to eliminate the “made-in image” of the Chinese smart phones, respondents were generally biased towards the product quality, brand acquaintance and their overall perceptions towards the personality of the said brands. Brand personality plays an integral role in easing communications with customers. They can, resultantly, relate conveniently to the identity and the personality traits possessed by such brands. Marketing professionals can essentially aim to foster a brand-customer personality congruence, which would ideally enable them to position their product offerings accordingly and design tailored advertising and marketing communication messages. A well-defined brand personality initiates greater customer purchase willingness coupled with amplified emotional attachment, trust and loyalty, thereby enhancing the significance of branding to managers. They can help develop frameworks to analyze behavioral intentions concerning consumer perception of brand personality

The current investigation was a prospective field validity study examining the discrimination and calibration properties of a general risk-need tool (Level of Service Inventory–Saskatchewan Youth Edition [LSI-Sk]) in a diverse sample of 284 court adjudicated youths, rated by their youth workers on the measure and followed up an average of 9.3 years. The overall risk level and need total demonstrated moderate predictive accuracy for general, violent, and nonviolent recidivism in the aggregate sample, although area under the curve (AUC) magnitudes fluctuated among gender and Indigenous ethnocultural subgroups. Variability in AUC values for the measure’s eight criminogenic need domains further reflected greater salience of certain needs among subgroups. Finally, clinician rated level of gang involvement incrementally predicted recidivism to varying degrees after controlling for overall risk and need. Implications for responsible use of risk assessment tools as part of individualized and gender/ethnoculturally responsive risk assessment practices with youth are discussed.

Abstract Background Researchers and policy makers have long suspected that people have differing, and potentially nefarious, motivations for participating in stated-preference studies such as discrete-choice experiments (DCE). While anecdotes and theories exist on why people participate in surveys, there is a paucity of evidence exploring variation in preferences for participating in stated-preference studies. Methods We used a DCE to estimate preferences for participating in preference research among an online survey panel sample. Preferences for the characteristics of a study to be conducted at a local hospital were assessed across five attributes (validity, relevance, bias, burden, time and payment) and described across three levels using a starring system. A D-efficient experimental design was used to construct three blocks of 12 choice tasks with two profiles each. Respondents were also asked about factors that motivated their choices. Mixed logistic regression was used to analyze the aggregate sample and latent class analysis identified segments of respondents. Results 629 respondents completed the experiment. In aggregate “study validity” was most important. Latent class results identified two segments based on underlying motivations: a quality-focused segment (76%) who focused most on validity, relevance, and bias and a convenience-focused segment (24%) who focused most on reimbursement and time. Quality-focused respondents spent more time completing the survey (p < 0.001) and were more likely to identify data quality (p < 0.01) and societal well-being (p < 0.01) as motivations to participate. Conclusions This information can be used to better understand variability in motivations to participate in stated-preference surveys and the impact of motivations on response quality.
