AbstractAs Industry 4.0 will greatly challenge employee mental workload (MWL), research on objective wearable MWL-monitoring is in high demand. However, numerous research lines validating such technology might become redundant when employees eventually object to its implementation. In a pilot study, we manipulated two ways in which employees might perceive MWL-monitoring initiatives. We found that framing the technology in terms of serving intrinsic goals (e.g., improving health) together with an autonomy-supportive context (e.g., allowing discussion) yields higher user acceptability when compared to framing in terms of extrinsic goals (e.g., increasing productivity) together with a controlling context (e.g., mandating use). User acceptability still panned out neutral in case of the former, however - feeding into our own and suggested future work.

Introduction. Development of methodical base of information hygiene, systematization of data on levels of information loadings and degree of their influence on working conditions of workers is actual.The purpose of the study was to measure and evaluate the levels of information mental load of office workers, to study the patterns of development of adverse functional States in this professional group.Materials and methods. The pilot study included 25 employees of scientific and educational institutions aged 25 to 65 years. Measurement of information mental load of workers was carried out on the basis of a point assessment. Psychodiagnostics of performance of participants of research was carried out by means of a package of standard techniques. Heart rate telemetry was carried out in employees in the conditions of professional activity.Results. The integral indicator of information mental load of the studied professional group was 37.3±7.2 points and was in direct connection with the coefficient of comfort of the workplace (r=0.5, p=0.01). A reliable dependence of the speed of information processing on the length of work experience (r=0.71, p=0.0001) was also established. In the low-stress group, high indices of stress, fatigue, monotony were recorded in the workers, in the senior group — signs of chronic fatigue. The employees during the shift registered an increase in sympathetic activation.Conclusions. The results of the psychophysiological survey of employees indicate the need to regulate the information load, the development and implementation of preventive measures to reduce professional stress.

: Various research showed that antioxidants can effectively overcome the damage caused by free radicals to the human health. Therefore, antioxidants are identified as one of the main directions in the development of health care and cosmetics products due to high demand in the market. This review mainly focuses on the phycocyanin, a type of natural antioxidant mainly found in cyanobacteria. This mini review summarizes the phycocyanin sources and numerous extraction methods of phycocyanin along with the analytical methods in determining its ability to suppress free radicals. Phycocyanin has been proven to play an important role in scavenging free radicals and enhancing the body’s antioxidant capacity. However, there are lack of long-term randomized clinical trial results that can be used as evidence in showing the benefits of phycocyanin. The existing phycocyanin extraction methods using solvents, ultrasonic-assisted, freeze-thaw and etc. can extract high-quality phycocyanin efficiently and quickly. Scientists are also trying to incorporate advanced technologies such as "Industry 4.0" to optimize and enhance the industrial production of phycocyanin. Lastly, this review also describes the difficulties faced during the phycocyanin production or extraction process and financial obstacles in order to achieve the popularization of phycocyanin.

The need for students to engage in critical thinking, collaboration, communication, and creativity when utilizing digital technologies is well established given the current push to prepare our students for future work expectations, often referred to as Industry 4.0. In this chapter, 54 Grade 5 students participated in online collaborative mathematical problem solving over a period of 9 weeks. Text-based discussion and software derived artefacts were investigated in an effort to understand how this approach aligns with these expectations. An examination of the frequency/density of technical mathematical vocabulary use and identified examples, Talk Types is used as a means to understand how often students within the online environment are likely to be engaged in work that might be considered productive. The findings of this study suggest that utilizing online synchronous and asynchronous collaborative learning platforms for the purposes of mathematical problem solving is a small but important approach to preparing students for the era of Industry 4.0.

PurposeThe purpose of this paper is to investigate how and when intrinsic (personal growth, affiliation, community contribution, health) and extrinsic (financial success, fame, physical appearance) goals affect individuals’ entrepreneurial intentions (EIs). The study uses goal contents theory to propose that intrinsic and extrinsic goals positively influence individuals’ EIs. The authors further argue that the collectivism moderates the effect of intrinsic and extrinsic goals on individuals EIs.Design/methodology/approachA survey was designed to collect data from business graduates at a university in Pakistan. The measurement model and the hypothesized model were tested using the structural equation modeling technique in MPlus 7.0.FindingsThe results suggest that all four intrinsic goals and three extrinsic goals positively affect individuals’ EIs. However, financial success and fame appear to be the most prominent determinants of EIs. Similarly, personal growth and contribution to community are strong predictors of individuals’ EIs. Conversely, health, physical appearance and affiliation motives were found to have a weaker effect on individuals’ EIs. Moreover, the results show that collectivist orientation negatively moderates the effect of intrinsic goals on individuals’ EIs, but positively moderates the effect of extrinsic goals. These results suggest that the EIs of individuals with high collectivist orientation are mainly induced by extrinsic goals, whereas intrinsic factors play a greater role in stimulating the EIs of individuals with low collectivism.Originality/valueExtant research has paid little attention to intrinsic and extrinsic goals as determinants of individuals’ EIs. Thus, this study explores how and when intrinsic and extrinsic goals develop individuals’ EIs. This study is the first of its kind to highlight the importance of individuals’ cultural orientation (collectivism) to determine the alternative role of intrinsic and extrinsic goals in developing individuals’ EIs. In addition, this study was conducted in a different cultural setting (i.e. South Asia), which provides an opportunity to expand the boundary conditions of the phenomenon by offering an alternative perspective on this issue.

The introduction of innovative digital tools for supporting manufacturing processes has far-reaching effects at an organizational and individual level due to the development of Industry 4.0. The FACTS4WORKERS project funded by H2020, i.e., Worker-Centric Workplaces in Smart Factories, aims to develop user-centered assistance systems in order to demonstrate their impact and applicability at the shop floor. To achieve this, understanding how to develop such tools is as important as assessing if advantages can be derived from the ICT system created. This study introduces the technology of a workplace solution linked to the industrial challenge of self-learning manufacturing workplaces. Subsequently, a two-step approach to evaluate the presented system is discussed, consisting of the one used in FACTS4WORKERS and the one used in the “Heuristics for Industry 4.0” project. Both approaches and the use case are introduced as a base for presenting the comparison of the results collected in this paper. The comparison of the results for the presented use case is extended with the results for the rest of the FACTS4WORKERS use cases and with future work in the framework.

Abstract Background People who smoke drugs (PWSD) are at high risk of both infectious disease and overdose. Harm reduction activities organized by their peers in the community can reduce risk by providing education, safer smoking supplies, and facilitate access to other services. Peers also provide a network of people who provide social support to PWSD which may reinforce harm reducing behaviors. We evaluated the numbers of supportive network members and the relationships between received support and participants’ harm-reducing activities. Methods Initial peer-researchers with past or current lived drug use experience were employed from communities in Abbotsford and Vancouver to interview ten friends from their social networks who use illegal drugs mainly through smoking. Contacts completed a questionnaire about people in their own harm reduction networks and their relationships with each other. We categorized social support into informational, emotional, and tangible aspects, and harm reduction into being trained in the use of, or carrying naloxone, assisting peers with overdoses, using brass screens to smoke, obtaining pipes from service organizations and being trained in CPR. Results Fifteen initial peer researchers interviewed 149 participants who provided information on up to 10 people who were friends or contacts and the relationships between them. People who smoked drugs in public were 1.46 (95% CI, 1.13-1.78) more likely to assist others with possible overdoses if they received tangible support; women who received tangible support were 1.24 (95% CI; 1.02-1.45) more likely to carry and be trained in the use of naloxone. There was no relationship between number of supportive network members and harm reduction behaviors. Conclusions In this pilot study, PWSD who received tangible support were more likely to assist peers in possible overdoses and be trained in the use of and/or carry naloxone, than those who did not receive tangible support. Future work on the social relationships of PWSD may prove valuable in the search for credible and effective interventions.

Psychometric Studies

It is presented the structure and psychometric studies of the “School Motivation Questionnaire”. The SMQ is a self-report questionnaire with 101 items, organized in sixteen scales that measure the students' goal orientations, the perceived classroom goal structures, the perceived teacher's autonomy support and the use of learning strategies. Twelve scales are adapted from the “Learning Climate Questionnaire”, “Perceptions of Instrumentality” and “Cuestionário a Estudiantes”. Four scales and five additional items are created new. The psychometric studies rely on a convenience sample consisting of 9thand 12thgrade students (N= 485) of Portuguese schools. The factorial and construct validity, verified through several exploratory factorial analyses to the data, presents a final solution of six factors, labelled Strategies (F1), Teacher Extrinsic Goals (F2), Student Extrinsic Goals, Externally Regulated (F3) Teacher Intrinsic Goals (F4), Student Extrinsic Goals, Internally Regulated (F5), and Student Intrinsic Goals (F6). The six-factor solution explains a significant variance of the scale results (53.95%). Good coefficients of internal consistency are obtained for all factors, never below (.858; F6). In sum there is strong evidence to support the multi-dimensionality of SMQ, upholding that the data obtained is exploratory and applies for future validation studies.

Extrinsic Goal

We examined relationships among goal attributes (difficulty and affective value) and goal types (mastery, performance, intrinsic, and extrinsic). Goal attributes of positive affect value and relative salience of positive value were higher for intrinsic goals, mastery goals, and more difficult goals, qualified by an interaction between difficulty and type of goal. Intrinsic goals were more affectively positive than extrinsic goals and mastery goals were more positive than performance goals, but these differences vanished if goals were also perceived as difficult. Results were consistent with goal-orientation theories and suggest the usefulness of integrating incentive-attribute concepts with goal-orientation theories.
