The problems of constructing a multiphase model of the phase field for the processes of phase transitions of the first kind are considered. Based on the Gibbs energy of the complete system expressed in terms of antisymmetrized combinations of phase fields, it is shown that the equations of dissipative dynamics of a locally nonequilibrium system follow from the condition of its monotonic decrease, preserving the normalization of the sum of variables by one and the following properties of the previously known two-phase model.

AbstractThe aim of this study is to develop a descriptive phase model for problem-posing activities based on structured situations. For this purpose, 36 task-based interviews with pre-service primary and secondary mathematics teachers working in pairs who were given two structured problem-posing situations were conducted. Through an inductive-deductive category development, five types of activities (situation analysis, variation, generation, problem-solving, evaluation) were identified. These activities were coded in so-called episodes, allowing time-covering analyses of the observed processes. Recurring transitions between these episodes were observed, through which a descriptive phase model was derived. In addition, coding of the developed episode types was validated for its interrater agreement.

BACKGROUND: Systemic Constellations Work (SCW) is a non-conventional method of dealing with organizational development and change that has been gaining popularity since the 1990s. OBJECTIVE: The goal of this study was to understand how kinesthetic and spatial sensations gained through SCW translate into knowledge with a particular focus on the longer-term organizational effects. METHODS: We performed semi-structured interviews and used triangulation of sources (constellator and clients) and methods (inductive, deductive coding and ethnographic approach). RESULTS: The study identified a phase model of SCW process revolving around organizational trauma enmeshed in the context of personal, organizational and social systemic fields. CONCLUSIONS: The results imply that SCW is a valid method of trauma healing and prevention.

This conceptual paper explores the development of coaching, as an expression of applied positive psychology. It argues that coaching is a positive psychology dialogue which has probably existed since the emergence of sophisticated forms of language, but only in the past few 1000years, has evidence emerged of its use as a deliberate practice to enhance learning. In the past 50years, this dialectic tool has been professionalised, through the emergence of professional bodies, and the introduction of formal training and certification. In considering the development of the coaching industry, we have used Rostow’s model of sector development to reflect on future possible pathways and the changes in the coaching industry with the clothing sector, to understand possible futures. We have offered a five-stage model to conceptualise this pathway of development. Using this insight, we have further reviewed past research and predicted future pathways for coaching research, based on a new ten-phase model of coaching research.

The Tromsø Interest Questionnaire (TRIQ) is the first suite of self-report subscales designed for focused investigations on how interest is experienced in relation to Hidi and Renninger’s four-phase model of interest development. In response to the plethora of varied interest measures that already exist in terms of theoretical grounding, form, and tested quality, the TRIQ subscales were designed with a consistent form to measure general interest, situation dependence, positive affect, competence level, competence aspirations, meaningfulness, and self-regulation answered in relation to some object of interest. Two studies testing the subscales’ performance using different objects of interest (self-chosen “object-general,” and prespecified “object-specific”) provide evidence of the subscales’ internal consistency, temporal reliability, and phase-distinguishing validity. Patterns across the two studies demonstrate that the TRIQ is a sufficiently reliable and valid domain-tailorable tool that is particularly effective at distinguishing phase 1 (triggered situational) from phase 4 (well-developed individual) interest. The findings raise interesting questions for further investigation about the distinction and distance between all interest phases, the push-pull factors that influence how interests evolve and additional subscales to add to the suite.
