Researchers and practitioners in basic and applied ecology provide to private or public clients assessment documents on various concern topics, such as the state of ecosystem components, the type of threats and their regime or the level of pressure and impact on biodiversity. These assessments, carried out by ecological field studies, may be strategic in addressing conservation research, plans and actions. Therefore, data provided in these documents should be characterized by a high reliability, that is, they should be based on standard methods and protocols, independence of data samples, absence of pseudo-replication, control of different levels of detectability among sampled individuals or species, high level of precision and accuracy etc. In this paper we propose a simple two-data-sheet format for a data reliability assessment of a professional study that may facilitate a rapid check of the more important requirements of a correct ecological field research. This format may be useful to students, technicians, professionals and researchers as well as public or private commissioning agencies (e.g. to evaluate the suitability of the study, possibly suggesting additions or modifications).

Abstract The potential of the reflective collective portfolio as a method of teaching, learning and assessment needs to be emphasized. The objectives is to assess and validate the quality of the collective portfolio as a method of teaching, learning and assessment in the training of health professional. Portfolio quality was analyzed using an inventory of analysis that was adapted and tested for this study. In total, 70 portfolios were analyzed. The Kappa test was used to analyze reproducibility, confirming the level of agreement between the appraisers. Descriptive analysis and the t-test were performed to compare results from the years the portfolios were produced. The constructs (layout and organization, comprehensive, reflective, critical and creative thought) exhibited Cronbach alpha values above 0.7, confirming the high reliability of the tool. The weighted Kappa test revealed an elevated and significant agreement (+90%) between the appraisers. Notably, certain items and constructs exhibited significant differences over the years. All of the constructs were assessed better from 2011 onwards, when the assessment and self-assessment tool was implemented. The success of the portfolio depends on strategies that provide students with greater clarity and forms of developing the method.

In this article we present the results of an evaluative study of an educational practice that focused on the training of participating referees at an international football tournament. The aim was to provide referees with a self-assessment instrument for analyzing and evaluating their refereeing performances at the tournament. The instrument also provided the teaching team with a source of information for detecting the referees’ daily needs and facilitating dialogical feedback processes in the context of a formative evaluation. Feedback was conducted at training meetings characterized by a participative, interactive and collaborative methodology in which video was used as a fundamental didactic resource. This case study employed a range of complementary methodological, qualitative and quantitative techniques and instruments. We analyzed 371 self-assessment reports produced after the matches by the 28 participating referees and evaluated the usefulness and contributions of the self-assessment tool. We also evaluated the referees’ level of satisfaction with the training proposal by analyzing their responses to a questionnaire and holding discussions with their trainers. The results revealed a high level of satisfaction and acceptance of both the instrument and the methodology developed at the work meetings. They also highlight the value of video content as teaching material, the quality of the feedback received, and the participatory, interactive and collaborative approach adopted at the sessions. This proposal is intended to be transferable to other situations and training contexts.

AbstractBackground: Comprehensive cardiac rehabilitation (CR) is a process designed to restore full physical, psychological and social activity and to reduce cardiovascular risk factors. Fear of movement may contribute to the occurrence and intensification of hypokinesia, and consequently affect the effectiveness of therapy. The aim of the study was to determine the level of barriers of physical activity in patients undergoing cardiac rehabilitation. The relationship between selected determinants (age and health selfassessment) and the kinesiophobia level were also examined.Material/Methods: 115 people aged 40-84 years were examined: 50 females (x = 63.46; SD = 11.19) and 65 males (x = 64.65; SD = 10.59) - patients undergoing cardiac rehabilitation at the Upper-Silesian Medical Centre in Katowice. In the present study, the Polish version of questionnaires: Kinesiophobia Causes Scale (KCS) and Short Form Health Survey (SF-36) were used. Questionnaires were supplemented by authors’ short survey.Results: The patients presented an elevated level of kinesiophobia, both in general as well as in individual components. In women, the kinesiophobia level was higher than in men. The psychological domain was a greater barrier of physical activity than the biological one. Strong, negative correlations of psychological and biological domains of kinesiophobia to physical functioning (SF-36) were noted in women. In the case of men, correlations were weaker, but also statistically significant.Conclusions: 1. Sex differentiates patients in their kinesiophobia level 2. Poor self-assessment of health is associated with a greater intensification of kinesiophobia 3. A high level of kinesiophobia may negatively affect cardiac rehabilitation process

The report shows the results of the Russian-Ethiopian historic and ethnographic expedition – a joint scientific project of two countries, successfully implemented in the early 1990s. Advanced results achieved by this expedition were much owed to participation of several leading Russian and Ethiopian scientific centers and universities – the Institute for African Studies, the Institute of Asian and African Countries at Lomonosov Moscow State University, Addis Ababa University and Institute for Ethiopian Studies, The Primakov Institute of World Economy and International Relations, and others. The participants of the expedition gathered and summarized a large body of data acquired during opinion polls, held in the course of the visits to a number of educational, medical, economic and manufacturing centers and organizations, including workshops, agricultural farms, banks, scientific centers. The collected scientific data has allowed, based on multi-factor analysis, to specify the nature of evolutionary processes in communal relations, efficiency of various aspects of federalism policy in a cosmopolitan country. Its value is reflected by applicability and sharp demand for a scientific view on one of the most troubled sides of social and political life of many African countries, and of the modern world. Based on the field research, a high number of articles and monographs have been prepared and published in the Russian Federation. They include “Report on Field Studies of Ethiopia Carried Out by Russian Historical, Ethnic, Sociological, Expedition, 1990–1992”, “Ethiopia: History, Culture and Ethnicity”, “Ethiopia: the Particular Features of Federalism”, “Drama in Modern Ethiopian Literature and Theatre”, “Mission in Ethiopia. African Policy of the USSR in the eyes of the Soviet Diplomat. 1956–1982”, two volumes of “Africa” encyclopedia and others.

IntroductionAdherence to cardioprotective dietary patterns can reduce risk for developing cardiometabolic disease. Rates of diet assessment and counselling by physicians are low. Use of a diet screener that rapidly identifies individuals at higher risk due to suboptimal dietary choices could increase diet assessment and brief counselling in clinical care.MethodsWe evaluated the relative validity and reliability of a 9-item diet risk score (DRS) based on the Healthy Eating Index (HEI)-2015, a comprehensive measure of diet quality calculated from a 160-item, validated food frequency questionnaire (FFQ). We hypothesised that DRS (0 (low risk) to 27 (high risk)) would inversely correlate with HEI-2015 score. Adults aged 35 to 75 years were recruited from a national research volunteer registry (ResearchMatch.org) and completed the DRS and FFQ in random order on one occasion. To measure reliability, participants repeated the DRS within 3 months.ResultsIn total, 126 adults (87% female) completed the study. Mean HEI-2015 score was 63.3 (95% CI: 61.1 to 65.4); mean DRS was 11.8 (95% CI: 10.8 to 12.8). DRS and HEI-2015 scores were inversely correlated (r=−0.6, p<0.001; R2=0.36). The DRS ranked 37% (n=47) of subjects in the same quintile, 41% (n=52) within ±1 quintile of the HEI-2015 (weighted κ: 0.28). The DRS had high reliability (n=102, ICC: 0.83). DRS mean completion time was 2 min.ConclusionsThe DRS is a brief diet assessment tool, validated against a FFQ, that can reliably identify patients with reported suboptimal intake. Future studies should evaluate the effectiveness of DRS-guided diet assessment in clinical care.Trial registration detailsClinicalTrials.gov (NCT03805373).

AbstractField studies were conducted over six seasons to determine the critical period for weed control (CPWC) in high-yielding cotton, using common sunflower as a mimic weed. Common sunflower was planted with or after cotton emergence at densities of 1, 2, 5, 10, 20, and 50 plants m−2. Common sunflower was added and removed at approximately 0, 150, 300, 450, 600, 750, and 900 growing degree days (GDD) after planting. Season-long interference resulted in no harvestable cotton at densities of five or more common sunflower plants m−2. High levels of intraspecific and interspecific competition occurred at the highest weed densities, with increases in weed biomass and reductions in crop yield not proportional to the changes in weed density. Using a 5% yield-loss threshold, the CPWC extended from 43 to 615 GDD, and 20 to 1,512 GDD for one and 50 common sunflower plants m−2, respectively. These results highlight the high level of weed control required in high-yielding cotton to ensure crop losses do not exceed the cost of control.

Abstract Background High quality health promotion (HP) depends on a competent workforce for which professional development programmes for practitioners are essential. The “CompHP Core Competencies Framework in HP” defines crucial competency domains but a recent review concluded that the implementation and use of the framework is lacking. The aim was to develop and validate a self-assessment tool for HP competencies, which should help evaluate training courses. Methods A brief self-assessment tool was employed in 2018 in Austria. 584 participants of 77 training courses submitted their post-course assessment (paper-pencil, RR = 78.1%). In addition, longitudinal data are available for 148 participants who filled in a pre-course online questionnaire. Measurement reliability and validity was tested by single factor, bifactor, multigroup, and multilevel CFA. A SEM proved for predictive and concurrent validity, controlling gender and age. Results A bifactor model (X2/df=3.69, RMSEA=.07, CFI=.95, sRMR=.07) showed superior results with a strong general CompHP factor (FL&gt;.65, wH=.90, ECV=.85), configurally invariant for two training programmes. On course level, there was only minimal variance between trainings (ICC&lt;.08). Structurally, there was a significant increase in HP competencies when comparing pre- and post-course measurements (b=.33, p&lt;.01). Participants showed different levels of competencies due to prior knowledge (b=.38, p&lt;.001) and course format (b=.16, p&lt;.06). The total scale had good properties (m = 49.8, sd = 10.3, 95%-CI: 49.0-50.7) and discriminated between groups (eg by training length). Conclusions The results justify the creation of an overall scale to assess core HP competencies. It is recommended to use the scale for evaluating training courses. The work compensates for the lack of empirical studies on the CompHP concept and facilitates a broader empirical application of a uniform competency framework for HP in accordance with international standards in HP and public health. Key messages The self-assessment tool provides a good and compact foundation for assessing HP competencies. It provides a basis for holistic, high quality and sustainable capacity building or development in HP.
