How organizational systemic constellations foster organizational trauma healing

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.

EVALUATION OF SURVIVABILITY OF A SHIP AFTER DAMAGE WITH APPLICATION OF A RISK CALCULATION METHOD

This paper contains calculations of risk for a selected damage case scenario. The calculations took place with use of a risk model designed for evaluating the safety of ships and were compared with the available and published industry standard (as included in SOLAS 2009) as well. The comparison of results is presented in the form of a discussion and concludes that exact risk levels can be obtained at any stage of the vessel's life. The currently valid method as included in SOLAS 2009 regulation provides limited information about the actual survivability of a vessel in emergency conditions. It is hence very difficult to compare the current probabilistic model with risk based survivability calculations to evaluate the actual safety provided by an investigated vessel should it subsequently be severely damaged.

Dietary assessment of schoolchildren: is food record a valid method?

Objective: To verify the relative validity of 24-hour Dietary Recall (R24h) as an assessment tool of schoolchildren´s food intake. Methods: A cross-sectional study of 41 students of a big Brazilian urban center, with a mean age of 0.25–8.35 years and 22% had excess weight. The R24h was applied a day after direct observation of intake (reference method). Weight and height were measured and the participants were categorized according to nutritional status (excess weight or not). The median energy, macronutrients (carbohydrate, protein and lipid) and micronutrients intake (iron, calcium and vitamin A) was compared. The Mann-Whitney test was conducted. Also, Spearman and kappa correlation coefficients were calculated. Results: Median energy and nutrient intake irrespective of nutritional status was similar according to the test and reference methods. Higher correlations were found for protein (r= 0.87) and iron (r = 0.71) but the values were more accentuated among students with excess weight. Kappa coefficient was low for vitamin A, moderate for carbohydrate and lipid, good for iron and protein, and very good for energy. Conclusions: R24h is a valid method for the assessment of food intake among schoolchildren. It is a potential practical and economical food assessment method, which can find application in epidemiological studies focused on food intake in early life.

Validity of Psychiatric Evaluation of Asylum Seekers through Telephone

The goal of the psychiatric assessment of asylum seekers is to evaluate the asylum seeker’s mental health and credibility. The shortage of mental health providers trained in this particular type of evaluation makes in-person evaluation not always feasible. Telephonic interview has been occasionally utilized to fill this void. The validity of such evaluations in assessing credibility has yet to be fully established. In the case of telephonic interviews, evaluators are limited with no access to facial or body language cues that can indicate deception or honesty. We will present a case of a client evaluated via telephone that was deemed credible and eventually released to pursue asylum in the US. Assessment of credibility relied solely on cues obtained from the client’s narrative, reported symptoms, and their style of interaction with the evaluator. We will highlight the findings from the client’s interview that supported credibility in the case and discuss the challenges of assessing asylum seeker’s credibility via telephonic interview. Telephonic evaluation of credibility can be considered a valid method despite major challenges, but psychiatric evaluators should be aware of the limitations of telephonic evaluations given the high possibility of secondary gains and deception.

Rich-Colour Mechanochromism of a Cyanostilbene Derivative with Chiral Self-Assembly

Mechanochromic luminophores exhibiting rich-colour transitions among multiple states have important potential applications, but few such compounds are known. Herein, chiral self-assembly fabrication is proposed as a valid method to realize...

Logical Principles of a Topological Explanation

We aim to demonstrate the applicability of Peirce’s iconic logic in the context of current topological explanations in the philosophy of science. We hold that the logical system of Existential Graphs is similar to contemporary topological approaches, thereby recognizing Peirce’s iconic logic (Beta Graphs) as a valid method of scientific representation. We base our thesis on the nexus between iconic logic and the so-called NonReduction Theorem. We illustrate our assumptions with examples derived from biology (protein folding).

Studies on the Pressure Buildup and Shear Flow Factors in the Cavitation Regime

Modeling tribological contacts is commonly based on the Reynolds equation. This study discusses the validity of conventional, averaged Reynolds simulations for systems including starvation regimes. Two fundamental assumptions that are used as common practice in many elasto-hydrodynamic (EHD) calculations, are debated. First, the use of a cavitation pressure (in most cases assumed to be zero) independent of the microscopic roughness. Second, the application of a shear flow factor, which is determined on a microscopic scale with a fully filled gap. The validity of these two assumptions is analyzed with simulations on the microscopic scale. For this purpose, simulations of partially filled contacts are carried out using the partially filled gaps model developed by the authors. The topographies, the filling level and the fluid distribution were varied. The simulations comply with established models for the fully filled state and show a distinct behavior for partial filling and different fluid distributions. Neglecting the contribution to pressure buildup and shear flow of partially filled domains is a valid method in most cases. However, as this study shows, near the fully filled regime, the domains should be handled with care.
