Objective. Social media have become one of the main technologies for promoting the university library. The purpose of the work is to characterize the main stages of organizing work in social media for librarians (SMM specialists and a working group) of the Scientific Library of the Belarusian National Technical University (BNTU). Methods. Statistical analysis tools made it possible to study in detail the corporate networks of the BNTU Library. A comparative analysis of the experience of maintaining BNTU accounts in social media by an SMM specialist and a working group of employees from various library departments was carried out. Results. The advantages and risks in the work of the group are summarized. The following areas highlighted: Team building; Communication and work organization; Creativity and creative power; Overcoming the challenges of group work; Content formation techniques; Potential. Conclusions. Working in a group produces creative and interesting content in large volumes. The experience of managing the process of forming a content policy in 2020 proves that the process has become more flexible and independent of the personality of an SMM specialist.

Abstract A general formalism is developed to evaluate the amount of work extractable from energy fluxes. It covers nonequilibrium cases when the concept of exergy is not relevant. The rate of work deficiency, which has been previously introduced as the total loss of exergy, is defined here as the total loss of work, which would have resulted if all the work were lost to the environment. New performance indicators are proposed. First, the work content factor gives the proportion of extractable work in a given amount of energy. Second, the work deficiency factor is a measure of the potential of improvement for the operation of energy conversion systems. Previous results reported in literature are particular cases of the general results obtained here. The formalism is used to evaluate the work rate extractable from the solar energy flux. Results are shown in cases where solar radiation interacts with materials without energy bandgap (metals) and with energy bandgaps (semiconductors), respectively.

Abstract Detecting the forces behind the success or failure of cultural products, such as books or films, remains a challenge. Three such forces are drift, context-biased selection, and selection based on content—when things succeed because of their intrinsic appeal. We propose a tool to study content-biased selection in sets of cultural collections—e.g. libraries or movie collections — based on the “shortlist effect”: the fact that smaller collections are more selective, more likely to favour highly appealing items over others. We use a model to show that, when the shortlist effect is at work, content-biased cultural selection is associated with greater nestedness in sets of collections. Having established empirically the existence of the shortlist effect, and of content-biased selection, in 28 sets of movie collections, we show that nestedness contributions can be used to estimate to what extent specific movies owe their success to their intrinsic properties. This method can be used in a wide range of datasets to detect the items that owe their success to their intrinsic appeal, as opposed to “hidden gems” or “accidental hits”.

Motivated by a recent disagreement about the claim that fluctuations in the free energy operator bound the charging power of a quantum battery, we present a critical analysis of the original derivation. The analysis shows that the above claim does not hold for both closed- and open-system dynamics. Our results indicate that the free energy operator is not a consistent quantifying operator for the work content of a charging quantum battery.

Introduction. With the growing number of females employed as factory workers, it is important to look into the phenomenon of burnout and related organizational climate affecting these workers. Objectives. The study's objectives were: 1) to come up with the indices of burnout among Filipino female factory workers and; 2) to come up with indices of organizational climate components of job autonomy, the content of the job, and nature of management through exploratory factor analysis. Methods. The secondary data used for this study were from a cross-sectional study involving 344 female factory workers. The indicators of the organizational climate were derived through exploratory factor analysis of items in the dataset. Exploratory Factor Analysis was used to reduce the variables into a fewer set of “Component Variables.” The technique explored the relationship of each indicator and then grouped them according to which component they were highly correlated. Using the factor loadings as weights, the index score was generated. The organizational climate indices were derived from the factor loading scores. Burnout Score was derived from respondents’ answers on nine items relating to burnout. The organizational climate indexes were also generated using factor analysis with these components- job autonomy, content of the job, and nature of management. Cronbach alpha was generated for all the items under each index to show the internal consistency and scale reliability. Results. There were 344 female respondents with a mean age of 26 (SD=5.02), and the majority were single (69.21%). Nine items were measured with the lowest average response “work is boring” (0.259 ± .560) for burnout indices. The highest mean answer for the item “work requires new skills or upskilling regularly” at 1.619 ± .762, suggesting that most respondents were required to upskill regularly. “Salary is not enough to meet worker’s needs” also has a high average response, suggesting that most respondents felt that their salary was insufficient to sustain their daily needs. The total burnout score indicates that workers experienced moderate burnout. The indices for burnout have good internal consistency and scale reliability (Cronbach alpha= 0.712). The organizational climate was grouped into Indexes through factor analysis, namely, Autonomy on Quality Index, Autonomy on Rest Index, Skilled work content Index, Physical work content Index, Hazardous work content Index, Health, Safety, and Compensation Index, and Training Index. Autonomy on Quality Index has a mean of 66.877 ± 31.934, suggesting that the autonomy on quality for respondents was moderately high, while Autonomy on Rest Index was 24.159 ± 30.788, suggesting that respondents have low autonomy on rest. The skilled work content index was high at an average of 70.801 ± 22.87, while physical work content and hazardous work content index were low at 29.398 and 25.377, respectively. Health, Safety, and Compensation index average was very low at 8.891 ± 8.524. Conclusion. This study came up with indices of burnout unique to female factory workers. The indexes were boredom/boring work, repetitious tasks, fast-paced work, work pressure, not sufficient compensation, work-home conflicts, upskilling, physically tiring, mentally tiring, and salary is not sufficient to meet basic needs. This study also came up with the indexes of organizational climate relating to job autonomy, content of job, and nature of management. The several items under each of these components were subjected to Factor Analysis to come up with indexes of organizational climate. Thus, the contribution of this study is coming up with a burnout index unique to the Filipino factory worker, not just based on subjective expert opinion, but data-driven and statistically derived.

Abstract Aim Surgical trainees deal with long hours and stressful work content. We aimed to assess the burnout levels in London trainees, and trial a mindfulness intervention. Method London core surgical trainees (CST1) were asked to complete an online survey including validated burnout scoring system (Oldenburg Inventory). 54 of a possible 78 trainees responded (69%). We then asked them to take part in a 2-week mindfulness intervention (approximately 5 minutes a day using the app Headspace). We later resurveyed. Results 60% of trainees who answered the survey feel ‘somewhat’ or ‘completely’ burnt out. Oldenburg burnout inventory calculates 85% of trainees to be ‘disengaged’ and 93% ‘exhausted’. 13/54 trainees completed the mindfulness training. 10 out of 13 trainees found this to be ‘somewhat’ or ‘massively’ helpful for burnout. Conclusions A high percentage of year one surgical trainees can be categorised as burnt out. The low uptake of mindfulness may speak to lack of capacity trainees have to invest in resources that will self-resolve this. We cannot say with significance whether mindfulness helped burnout (and length of trial could be too short) but the majority who did trial report positive experience with mindfulness.

AbstractIn recent years, the increasing concern about the labour market implications of technological change has led economists to look in more detail at the structure of work content and job tasks. Incorporating insights from other traditions of task analysis, in particular from the labour process approach, as well as from recent research on skills, work organisation and occupational change, in this paper we propose a comprehensive and detailed taxonomy of tasks. Going beyond existing broad classifications, our taxonomy aims at connecting the substantive content of work with its organisational context by answering two key questions: what do people do at work and how do they do their work? For illustrative purposes, we show how our approach allows a better understanding of the impact of new technologies on work, by accounting for relevant ongoing transformations such as the diffusion of artificial intelligence and the unfolding of digital labour platforms.

The present study examined the processes of supervisees’ non-disclosure in the supervision of psychotherapy. The purpose of the study was to determine the frequency of non-disclosure by supervisees, the content of non-disclosure and the reasons for it. The study involved 50 supervisees (42 women and 8 men), with different professional developmental levels and belonging to various psychotherapeutic schools. Study participants completed the Questionnaire of Significant Aspects of Supervision after each of two consecutive supervision sessions. Half of the sessions were conducted in individual and half of the sessions in group settings. Altogether, 90 completed questionnaires were used in the study. Interviews were performed with ten of the supervisees.Data was coded according to principles of grounded theory (Corbin and Strauss, 2015). Our findings revealed that non-disclosure was present in 21% of the sessions. Supervisees conceal dissatisfaction with supervisors and their work, content related to the supervision group, information related to psychotherapeutic work, personal topics and topics related to wider professional activity. The reasons for non-disclosure were: not feeling safe enough in the supervisory relationship or the supervision group, concern for the supervisor, shame and self-criticism. These findings are significant both for the practice and for further research of supervision.
