Evaluation of Changes in Psychophysical Performance during the Afternoon Drop off in Work Capacity after the Exposure to Specific Color of Light

The aim of the study was to define whether changes in psychophysical performance will occur after the exposure to light of a specific color during the early afternoon decrease in work capacity. The evaluation of psychophysical performance was carried out on a group of 50 subjects using the following tools: Grandjean Scale, Attention and Perceptiveness Test (TUS), and GONOGO test. The study was performed for exposure to reference light, white light enriched by blue light (WBL), and white light enriched by red light (WRL). The analysis of psychophysical performance results indicates the positive influence of a specific color of light on different factors of psychophysical performance. Exposure to WRL among participants from the 22–34 subgroup contributed to an increase in the number of correct tests and the speed of work as well as a decrease in the number of mistakes, less boredom, and higher performance. The exposure to WBL among participants from the 55+ subgroup decreased the number of mistakes and reduced the response time. The results are consistent with the outcomes of previous research carried out on an international level, confirming that blue and red light are effective at increasing psychophysical performance. It was demonstrated that the psychophysical performance increases also when blue or red light is a significant component in the spectrum of white light.

Perception of Greed and Unfairness

In the past decade, interest in greed among empirical business scholars has emerged. It starts with the trailblazing attempt to analyze greed by Wang and Murnighan (2011), followed by the development of the Dispositional Greed Scale by Seuntjens et. al. (2015a, 2015b), which serves as a basis for the research done by Zhu et. al. (2019) and Bao et. al. (2020). However, since Seuntjens’ work, the overwhelming focus has been on greed as a disposition to “always want more and never being satisfied with what one currently has” (Seuntjens et. al., 2015b). Independently, Cheung (2019) proposed a more sophisticated philosophical analysis of greed, which argues that there are three dimensions of greed, and its dimension of unfairness has largely been neglected. This article reports on our investigation of that neglected dimension of greed. Our cross-cultural study (n=395) shows that when the rating of greediness was not very high, the perception of greed went hand in hand with the perception of unfairness, such that there was a positive linear association between the two. The demographics of the participants suggests that the sample is diverse enough to make a broad generalization. The result of this study confirms the conception of greed in Cheung (2019), which claims that the perception of unfairness, i.e., (2) above, is a significant component of perceived greed. Cheung’s account of greed can also explain the data when the rating of greediness is very high, but logically there could be other explanations.

Levers of family firms’ resilience in times of crisis

Although the academic literature argues that family firms are more resilient than non-family firms, the reasons for this presumed superiority are still not clearly identified. In addition, while family firms are a significant component of the economic landscape, research has evidenced variations in this organizational form such that some family firms seem to be more resilient than others. The following reflection will seek to provide some elements of analysis of the resilience of these companies in times of crisis.

PEDAGOGICAL CREATIVITY AS A SIGNIFICANT COMPONENT IN THE PROCESS OF PROFESSIONAL TRAINING OF THE FUTURE PRIMARY SCHOOL TEACHER

The main components that make up the professional activity of a teacher are professional knowledge and skills, didactic, communicative, organizational, research and creative abilities. Among the mentioned components of the pedagogical activity, one of the most significant is creative, because today society needs a specialist who has not only a functional readiness for professional activity but also develops as a creative person with clear goals. The new Ukrainian school needs a primary school teacher, who is creative in his work with junior schoolchildren. The effectiveness of the activities largely depends on how creative their pedagogical position will be, the formation of which takes place in the higher education environment of the university. The article analyses pedagogical creativity as a significant component in the process of professional training of future primary school teachers. The concept of “creativity”, “pedagogical creativity” in the context of professional training of future primary school teachers of higher education institutions is considered. The paper reveals that the formation of pedagogical creativity is facilitated by the introduction of technological elements of personality-oriented learning in lectures, seminars and practical classes. The author emphasized that the foundation for the formation of pedagogical creativity of future primary school teachers is pedagogical interaction, in which the teacher and the applicant are subjects of the educational environment of the pedagogical institution of higher education, the formation of cognitive interests and needs of students, control and self-control. It was found that pedagogical creativity is a significant component in the professional activity of primary school teachers, and hence in the training of future primary school teachers in higher education, as it is a necessary condition for the educational process, which gives teachers the opportunity to act original and creative in different situations that optimizes the learning process of junior students. Keywords: creativity; pedagogical creativity; future primary school teacher; professional training; educational environment; higher education institution; professional competencies; junior schoolchildren; pedagogical interaction.

Marine Biopolymers: Applications in Food Packaging

Marine sources are gaining popularity and attention as novel materials for manufacturing biopolymers such as proteins and polysaccharides. Due to their biocompatibility, biodegradability, and non-toxicity features, these biopolymers have been claimed to be beneficial in the development of food packaging materials. Several studies have thoroughly researched the extraction, isolation, and latent use of marine biopolymers in the fabrication of environmentally acceptable packaging. Thus, a review was designed to provide an overview of (a) the chemical composition, unique properties, and extraction methods of marine biopolymers; (b) the application of marine biopolymers in film and coating development for improved shelf-life of packaged foods; (c) production flaws and proposed solutions for better isolation of marine biopolymers; (d) methods of preparation of edible films and coatings from marine biopolymers; and (e) safety aspects. According to our review, these biopolymers would make a significant component of a biodegradable food packaging system, reducing the amount of plastic packaging used and resulting in considerable environmental and economic benefits.

Phase separation near the charge neutrality point in FeSe1-xTex crystals with x < 0.15

Our study of FeSe$ _ {1-x}$Te$ _ {x}$ crystals with x $<$ 0.15 shows that the phase separation in these compositions occurs into phases with a different stoichiometry of iron. This phase separation may indicate structural instability of the iron plane in the studied range of compositions. We tentatively propose an explanation of the structural instability of the iron plane in the studied layered compounds in terms of the possible change in the bond polarity and the peculiarity of the direct $d-d$ exchange in the iron plane in the framework of the basic phenomenological description such as the Bethe-Slater curve. With this approach, when the distance between iron atoms is close to the value at which the sign of the magnetic exchange for some $d$ orbitals changes, structural and electronic instability can occur. Anomalies in the crystal field near the point of charge neutrality can also be a significant component of this instability.

The Opportunities for Specialist Academic Libraries to Integrate Information Literacy into Faculty Curricula

<p>This research project sought to determine the opportunities for librarians in specialist academic libraries to integrate information literacy into faculty curricula. Information literacy is becoming recognized as increasingly important as a graduate competency by universities, and is a significant component of lifelong learning. The ability of librarians to collaborate with academic faculty staff in order to provide information literacy instruction to students is crucial. The researcher employed a qualitative methodology for the project, interviewing subject librarians who worked with faculty from two specialist academic libraries at the University of Auckland. The theoretical framework of the project was based on the works of Hardesty and Farber, when considering factors relating to librarian-faculty relationships, and of Owusu-Ansah and Grafstein, among others, on factors relating to information literacy. Analysis of data collected yielded results falling within three main areas. Subject librarians within the specialist academic libraries studied considered themselves to be highly accessible, being able to be contacted in person very easily by the academics whose subject discipline resources they administered. They also felt that they were visible, both within the libraries themselves, and within the wider faculty area within which the libraries were situated. The ability to employ information literacy components which were tailor-made for particular courses, grounded within specific subjects facilitated both lecturer and student buy-in. These three factors contribute to the inclusion which subject librarians in specialist academic libraries feel within a community involving all members of faculty, united by geographical location and subject discipline, and which greatly facilitates the integration of information literacy into curricula.</p>

Form-Based Regulations to Prevent the Loss of Urbanity of Historic Small Towns: Replicability of the Monte Carasso Case

Small towns are a significant component of the landscape in Europe and a key element of its cultural heritage. Currently, they face socio-economic crisis and spatial disintegration. Against this background, the spatial transformation of the Swiss town of Monte Carasso is of particular interest. It was initiated in the 1970s as a design intervention made by the architect Luigi Snozzi and eventually constituted a local spatial policy with a scope to maintain or even restore town urbanity and identity. This paper describes the case through its decomposition into primal elements such as context, main procedure elements, supplementary action, and obtained results. The results were measured by calculating urban parameters and observations compared with the adjacent town of Sementina, whereby they proved that the policy is effective. In the next step, a synthetic diagram was proposed that describes the interrelation between specific elements of the procedure. It was then modified to serve as a model for other possible contexts. Finally, its main potentials and limitations were described. It was concluded that the construction of the Monte Carasso urban regulatory mechanism has the potential to be replicated elsewhere. However, some of its features need to be rethought—mainly the role of an individual architect, which was highly exposed in the original case.

The ubiquitous creeping segments on oceanic transform faults

Oceanic transform faults are a significant component of the global plate boundary system and are well known for generating fewer and smaller earthquakes than expected. Detailed studies at a handful of sites support the hypothesis that an abundance of creeping segments is responsible for most of the observed deficiency of earthquakes on those faults. We test this hypothesis on a global scale. We relocate Mw ⩾5 earthquakes on 138 oceanic transform faults around the world and identify creeping segments on these faults. We demonstrate that creeping segments occur on almost all oceanic transform faults, which could explain their deficiency of earthquakes. We also find that most of the creeping segments are not associated with any large-scale geological structure such as a fault step-over, indicating that along-strike variation of fault zone properties may be the main reason for their existence.
