Two thought experiments are discussed which suggest, first, a geometric interpretation of the concept of a (say, vector) potential (i.e., as a kinematic quantity associated with a transformation between moving frames of reference suitably related to the problem) and, second, that, in a quantum treatment one should extend the notion of the equivalence principle to include not only the equivalence of inertial forces with suitable “real” forces, but also the equivalence of potentials of such inertial forces and the potentials of (...) suitable real forces. The two types of cancellation are physically independent of each other, because of the Aharonov-Bohm effect. Finally, we show that the latter effect itself can be understood “geometrically” as a kinematic effect arising upon the transformation between the two reference frames. (shrink)

We interpret the (formal) postulates of measurement in quantum theory in terms of measurement procedures that can be done in the laboratory (at least in principle).

Upshot: In the model simulation and the human experiment, we observed that attention shifted from a tool to a task. This was accompanied by bodily extension. However, our experiments lack a sense of bodily incorporation (the sense of ownership. Based on the valuable commentaries, we would like to discuss the necessary conditions for possible bodily incorporation in terms of redundant degrees of freedom, synchronous visual tactile stimulation, and 1/f noise.

Open peer commentary on the article “Consciousness as Self-Description in Differences” by Diana Gasparyan. Upshot: Gasparyan’s article ignores the inherent tension of being a human who is both a subject and an object at the same time. Any theory of consciousness must include both of these dimensions.

Suffering repeated experiences of moral distress in intensive care units due to applications of futility reflects on nurses’ patient care negatively, increases their burnout, and reduces their job satisfaction. This study was carried out to investigate the levels of job satisfaction and exhaustion suffered by intensive care nurses and the relationship between them through the futility dimension of the issue. The study included 138 intensive care nurses. The data were obtained with the futility questionnaire developed by the researchers, Maslach Burnout (...) Inventory and Minnesota Satisfaction Questionnaire. It was determined that nurses who agreed to the proposition that the application of futility demoralizes health-care professionals had low levels of job satisfaction but high levels of depersonalization. It was determined that nurses had moderate levels of job satisfaction, emotional exhaustion, and personal achievements but high levels of sensitivity. Nurses’ job satisfaction and sensitivities are positively affected when they consider that futility does not contradict the purposes of medicine. (shrink)

There is a need for empirically based research on social and ethical challenges related to informed consent processes, particularly in studies focusing on adolescent sexual and reproductive health. In a pilot study of a school-based pregnancy prevention intervention in rural Zambia, the majority of the guardians who were asked to consent to their daughters’ participation, refused. In this paper we explore the reasons behind the low participation in the pilot with particular attention to challenges related to the community engagement and (...) informed consent process. The pilot was implemented in two schools and examined the acceptability of a package of interventions including economic support to families to keep their girls in school, pocket money for girls, youth club meetings on reproductive health, and community meetings to sensitize the community. Focus group discussions were conducted with girls who participated in the pilot, boys in their class and with parents. Individual semi-structured interviews were conducted with teachers, peer educators and community health workers involved in the coordination of the intervention as well as with religious and traditional leaders. Data were analyzed through thematic analysis. The findings indicate that inadequate use of recognized community communication channels during the community engagement process and dissemination of information about the pilot resulted in limited understanding of the pilot concept by the community. This surfaced through uncertainty and fear that the intervention may result in loss of control over daughters, worries about why money was provided unconditionally to girls, and suspicion of links to satanism. The sense of insecurity appeared to be exacerbated by low literacy levels, poverty, fear of loss of bride wealth, perceived disregard for local perceptions of social status, and scanty trust in the actors implementing the pilot. Inadequate use of locally appropriate channels in the dissemination of information created room for interpretation and facilitated development of mistrust, undermining the conditions for community engagement and actual informed consent. A key lesson learnt is the importance of taking seriously the complexity of local values and structures that may impact people’s capability to consent or not consent to a study in an informed manner.

В статті досліджуються механізми виникнення концептосфери Інтернету «розумних» речей. Представлено розуміння процесів трансферу з ментального плану людини у простір культури концептів. Дослідження вказує на важливість еволюції ментального плану людини для процесів трансформації когнітивно перетворювальної практики людини. Такий феномен техніки, як ІРР, сформував нове ментальне середовище – концептосферу «ІРР», яка має важливе значення для формування ментального плану людини. Концептосфера «ІРР» має вплив у всіх сферах діяльності людини: науці, техніці, культурі, медицині, економіці, побуті тощо. Концептосфера «ІРР», як і сама техносфера ІРР, характеризується (...) аутопоезисом та автономністю. (shrink)

This study had two purposes: to explore the components of the pedagogical content knowledge (PCK) of an experienced elementary science teacher and to reveal the presumed interactions among these components. A naturalistic inquiry was conducted as a single case study in which in-depth qualitative data were gathered through semi-structured interview questions. After the theory-based and data-driven analysis of the qualitative data, the verbal communication was quantitated into numerical data for the enumerative analysis. The results revealed that the teacher’s knowledge of (...) students’ understanding and difficulties, knowledge of the elementary science curriculum and knowledge of instructional strategies and representations were found to be mostly intersected PCK components, whereas orientations towards teaching science and knowledge of assessment in science had limited connections to the other components. Further discussions and context-based suggestions are given regarding professional development programmes. (shrink)
