Stone roof coverings have existed for hundreds of years now, but their application in contemporary representative architecture is quite different than it was in former times, and accordingly the underlying constructional details are much more complicated. The main role of the roof in today's architecture is to emphasize the abstract building volume and its homogeneity. The design (visual appearance) has priority over constructional considerations, while at the same time requirements for thermal insulation and the watertight buildup of the building envelope are rising. This is a big challenge for the design of the constructional details, since traditional methods do not apply anymore: almost all of the water gets under this exterior cladding where a completely waterproof underlayer is needed. Therefore a new type of constructions is borne. In this article I try to present innovative constructional alternatives for stone cladded roofs and try to define guidelines for their planning. These alternatives were created and refined based on analysis of historical and contemporary examples, the examination of the specific conditions and requirements that affect cladded roofs, their expected performance over their life-span, the difficulties that arise under construction and my work experience. I created seven groups, according to the method for fixing the individual stone elements, since this is the detail that most affects the buildup of the underlying structure. A new approach is needed with these unconventional constructions, with a much more detailed inventory of every little feature of the building in question. But since these features vary violently with the architectural conception the exact constructional solutions are usually unique as well.

Buildings consume over 40% of the total energy in modern societies, and improving their energy efficiency can significantly reduce our energy footprint. In this article, we present WattScale, a data-driven approach to identify the least energy-efficient buildings from a large population of buildings in a city or a region. Unlike previous methods such as least-squares that use point estimates, WattScale uses Bayesian inference to capture the stochasticity in the daily energy usage by estimating the distribution of parameters that affect a building. Further, it compares them with similar homes in a given population. WattScale also incorporates a fault detection algorithm to identify the underlying causes of energy inefficiency. We validate our approach using ground truth data from different geographical locations, which showcases its applicability in various settings. WattScale has two execution modes—(i) individual and (ii) region-based, which we highlight using two case studies. For the individual execution mode, we present results from a city containing >10,000 buildings and show that more than half of the buildings are inefficient in one way or another indicating a significant potential from energy improvement measures. Additionally, we provide probable cause of inefficiency and find that 41%, 23.73%, and 0.51% homes have poor building envelope, heating, and cooling system faults, respectively. For the region-based execution mode, we show that WattScale can be extended to millions of homes in the U.S. due to the recent availability of representative energy datasets.

Musical Context

Attention to subtle changes in music, whether inadvertent or purposeful, occupies a great deal of practice and rehearsal time for the performer. Regardless of the extremely subtle acoustic changes that have been found to be perceptible within almost all studies, it is the total overall effect that most occupies the individual listener. This study investigated perception of digitally edited performances of Johann Strauss's Blue Danube Waltz, all performed by the Vienna Philharmonic Orchestra with various conductors across an 18-year period. Two groups of string musicians in grades 7 through 12 participated ( N = 104). One group was an intact class; the second was a group of summer camp students. All participants listened to two conditions: (a) audio only and (b) audio-video combination. Results indicated that there were no significant differences between groups and that no one was able to identify correctly that there were five different conductors in the audio-only condition. Results were much the same as earlier research with college students. In addition, many students indicated that there were differences in the audio portions of the two conditions when in fact there were not.

In A Theory of Justice, John Rawls assumes that the principles of justice are for individuals in a society, and in general he assumes that the society is an ethnically homogeneous state. He thus follows the tradition associated with the dominant form of the social contract theory, which focuses on the individual and the state. His assumptions neglect the fact that almost all states are ethnically plural or heterogeneous, and that many of them confer special status and rights on ethnic groups as collective entities; for example, many of them confer special status and rights on indigenous groups, on groups disadvantaged by prior discrimination, and on minorities and other groups conceded a right to survive as distinct cultural entities. Status and rights for groups necessarily mean differentiation among individuals depending on their membership; and this in turn means that a theory of justice that focuses on the individual and neglects the group both fails to account for existing practices and fails to give guidance where the practices are at issue.

This article points out that the process of modernizing the Russian Federation’s education system is aimed at developing such a professional body of teachers that would be prepared to solve issues associated with improving the quality of education. Given such a situation, the need arises for finding effective means of developing the professional competencies of teachers. One direction for modernizing the education system would be a national system of advancement for teachers, which postulates the need for creating the right conditions for the formal and informal training of educators. Given the context, socio-professional teachers’ unions turn out to be especially vital. The goal of this study was to identify how active participation in the practices of such organizations is connected to a young teacher’s professional growth. The study was conducted in Orel Province. Members of the regional young math teachers’ association were selected to be the object of research, with questionnaire survey used as the research method. The study focused on several aspects of teaching: professional difficulties faced by young educators, the mentorship system, an educator’s value orientations, professional growth. The results of the study allowed for identifying three groups of educators, the first one being young teachers who do not actively participate in educational events. The second group included teachers who do not share their own methodical expertise, but partake in seminars and master classes. The third group consists of educators who publically share their experience and are prepared to think of new ideas for future events. The article shows that the Association’s active participation in various events significantly affected the individual value orientations of trade professionals. Those educators who shared their publically work experience demonstrated a higher degree of professional aptitude in performing their jobs within the national system of teachers’ training. ctive efforts as members of the Association helped young educators quickly adapt within their professional community and establish firm social connections with their colleagues. The authors suggest the need for developing a system of mentorship in educational institutions, which would utilize resources provided by socio-professional teachers’ unions.

The effect of the reportedly low ionizing radiation doses, such as those very often delivered to patients in interventional cardiology, remains ambiguous. As interventional cardiac procedures may have a significant impact on total collective effective dose, there are radiation protection concerns for patients and physicians regarding potential late health effects. Given that very low doses (<100 mSv) are expected to be delivered during these procedures, the purpose of this study was to assess the potency and suitability of current genotoxicity biomarkers to detect and quantitate biological effects essential for risk estimation in interventional cardiology. Specifically, the biomarkers γ-H2AX foci, dicentric chromosomes, and micronuclei, which underpin radiation-induced DNA damage, were studied in blood lymphocytes of 25 adult patients before and after interventional cardiac procedures. Even though the mean values of all patients as a group for all three endpoints tested show increased yields relative to baseline following medical exposure, our results demonstrate that only the γ-H2AX biomarker enables detection of statistically significant differences at the individual level (p < 0.001) for almost all patients (91%). Furthermore, 24 h after exposure, residual γ-H2AX foci were still detectable in irradiated lymphocytes. Their decline was found to vary significantly among the individuals and the repair kinetics of γ-H2AX foci was found to range from 25 to 95.6% of their maximum values obtained.

Research and commercial trawl catches of humpback shrimp Pandalus hypsinotus from the Tatar Strait (Japan Sea) in 2004–2020 were investigated, with bioanalysis of about 45 thousand specimens. Average timing of group molting, spawning, and eggs laying are determined, terms of gonads and eggs development are estimated. Prespawning and molting of the females occur between January-April, with the peaks in early February and middle February, respectively. All oviparous females have 30–40 days to lay eggs, and molt during 50–55 days; the peak of the eggs laying occurs in late June. The males molt in July-August, afterwards the largest individuals change gender and new intersexes are formed. The males have the second molting in October-December, with the peak in late November. In January, after finish of the males molting, a new annual reproduction cycle starts from the prespawning molting of females. Both vitellogenesis and embryogenesis are observed through the year, though females with developing gonads prevail from August to January (because of a long time span between winter and summer moltings while the egg carrying continued 15 months) but oviparous females — from February to July. The individual reproductive cycle of Pandalus hypsinotus in the Tatar Strait lasts 24 months, with 9 months of vitellogenesis (quick growth of gonads) and 15 months of embryogenesis. During the 2-year reproductive cycle, most of females pass through the following stages: i) gonads development (just after eggs laying) when almost all oviparous females (up to 95 % in May) have green gonads under carapace that corresponds to the stage of development «eggs laid — gonads weakly developed»; ii) summer molting from August when females lose hairs on pleopods and the gonads growth accelerates; iii) respawning in January-March (together with the firstly spawning intersexes, with slight delay of the latter); iv) initial developing of eggs during summer; v) stage of «eyed eggs» from December to March; and vi) eggs laying and molting from late March to late May; then the 2-year reproductive cycle repeats.

We cultured human umbilical cord blood erythropoietic precursors in methyl cellulose clonal assay and analyzed the synthetic rates of Hb A and Hb F in individual erythropoietic bursts. Hemoglobin was labeled with 14C-amino acids in culture, separated by slab gel isoelectric focusing techniques, and quantitated by fluorographic methods. Almost all bursts exhibited both Hb A and Hb F in varying ratios. Frequencies of the individual bursts differing in percentage Hb F biosynthesis had normal distributions. Natal erythropoietic precursors appeared to be randomly committed to Hb F synthesis.

The article analyzes the problem of professionalization of the individual in pedagogical activity. The results of an empirical study of the ideas of teachers of different ages about the object of their professional activity are presented. It is shown that at each stage of professionalization, with an increase in the length of teaching experience, the assessment of the attitude to time changes, and through this – the assessment of the individual's attitude to the surrounding reality in General, as well as to himself, his experience and future prospects. Significant relationships between indicators of teachers ' perceptions of the object of professional activity and indicators of the time perspective of teachers of different ages are shown. The study involved 148 College teachers. Work experience varies from 1 year to 40 years. Age limits from 20 to 63 years. To confirm the research hypothesis that there may be significant relationships between professional ideas and time perspectives among teachers of different ages, we used a set of methods, including: "Questionnaire aimed at the study of ideas about the object of activity (E. I. Rogova)," F. Zimbardo's time perspective Questionnaire (ZTPI)". Methods of mathematical and statistical processing, presentation of the obtained data: descriptive statistics, determination of the reliability of differences: according to the Kruskal-Wallace criterion. Empirically, it is established that there are significant relationships between the assessment of attitudes to time and ideas about the object of activity in teachers of different ages.

Abstract.Emotional intelligence is a set of skills that enable the individual to manage their own emotions and those of others, making it easier to achieve established objectives and create wellbeing at organizational, academic and personal level. Job satisfaction is a positive emotional assessment of work experience that is related to the productivity and well-being. In this regard, the aim of this study was to analyze to what extent emotional intelligence can increase job satisfaction. To achieve this goal are counted with a mixed sample of 377 workers (M = 172, F= 205) in public and private companies of Portugal, that answered a questionnaire previously validated by other authors, which mediates the three main variables of study: emotional intelligence, organizational stress and job satisfaction. The results obtained through the Pearson correlation tested the hypotheses in the expected direction with significant negative correlation between emotional intelligence and organizational stress and a significant positive correlation between emotional intelligence and job satisfaction. Emotional intelligence workers anticipated job satisfaction R multiple = .332, R2 = .111, F (6, 370) = 7.66, p <.001, the most significant variables as predictors of emotional intelligence, Auto - courage (? = .184, p = .001), and Empathy and emotional contagion (? =.141, p = .016).Keywords: Emotional Intelligence and Job Satisfaction.Resumen.La inteligencia emocional consiste en un conjunto de habilidades que permiten al individuo manejar sus propias emociones y las de los demás, por lo que es más fácil alcanzar los objetivos establecidos y crear bienestar a nivel organizacional, académico y personal. La satisfacción laboral representa una valoración emocional positiva sobre la experiencia de trabajo, que está relacionado con la productividad y el bienestar. En este sentido, el objetivo de este estudio es analizar hasta qué punto la inteligencia emocional puede aumentar la satisfacción laboral. Para llevar a cabo este objetivo se contó con una muestra mixta de 377 trabajadores (M = 172, F = 205) de empresas públicas y privadas de Portugal, que respondieron a un cuestionario previamente validado por otros autores, que medía las dos variables principales de este estudio: inteligencia emocional y satisfacción laboral. Los resultados obtenidos a través de la correlación de Pearson probaron la hipótesis en la dirección esperada, una correlación positiva significativa entre la inteligencia emocional y la satisfacción laboral. La inteligencia emocional de los trabajadores anticipa la satisfacción laboral R múltiplo = .332; R2 = .111, F (6, 370) = 7.66, p < .001, siendo las variables más significativas como predictores de inteligencia emocional, el Auto–coraje (? = .184, p= .001) y, la Empatía y el contagio emocional (? = .141, p = .016).Palabras claves: inteligencia emocional y satisfacción laboral.

This chapter presents a selection mainly of twentieth-century scholarly opinion, both Sunni and Shi’a, on wasaṭiyyah and its role and manifestation in the textual data and historical development of Islamic scholarship, as well as the management of community affairs. Wasaṭiyyah relates closely to justice, but it is multifaceted and tends to influence almost all aspects of the individual conduct, as well as relations in society and with the outside world. The chapter discusses how wasaṭiyyah begins in the inner self of the individual and from there spreads out to influence relations with others and one’s surrounding environment, concluding with the point that rejecting extremism and embracing moderation are the keys toward treating others with dignity, accepting our differences, and coexisting with each other in peace and harmony.
