This study provides an overview of components of teacher identity that are found in quantitative measurement instruments; and reports on the psychometric quality of these measurement in- struments. Our search included studies that assessed components of teacher identity published in English-written, peer-reviewed articles between 2000 and 2018. We analyzed a total of 59 components in 20 studies. After we categorized the components on the basis of a substantive analysis, six main domains of teacher identity became apparent: Self-image, Motivation, Commitment, Self-efficacy, Task perception, and Job satisfaction. Whereas the overall psycho- metric properties of the measurement instruments used in the different studies were acceptable to good, our systematic overview revealed several conceptual and methodological issues that need to be resolved. The results may contribute to the further operationalization of the complex construct of teacher identity.
OBJECTIVES: The INTERMED Self-Assessment questionnaire (IMSA) was developed as an alternative to the observer-rated INTERMED (IM) to assess biopsychosocial complexity and health care needs. We studied feasibility, reliability and validity of the IMSA within a large and heterogeneous international sample of adult hospital in- and outpatients, and its predictive value for health care utilization (HCU) and quality of life (QoL).METHODS: 850 participants aged 17 to 90 from 5 countries completed the IMSA and were evaluated with the IM. The following measurement properties were determined: feasibility by percentages of missing values; reliability by Cronbach's alpha; interrater agreement by intraclass correlation coefficients (ICCs); convergent validity of IMSA scores with mental health (SF-36 emotional well-being subscale and HADS), medical health (CIRS) and QoL (EQ-5D) by Spearmans rank correlations; predictive validity of IMSA scores with HCU and QoL by (generalized) linear mixed models.RESULTS: Feasibility, face validity and reliability (Cronbach's alpha 0.80) were satisfactory. ICC between IMSA and IM total scores was .78 (95% CI .75-.81). Correlations of the IMSA with the SF-36, HADS, CIRS and EQ-5D (convergent validity) were -.65, .15, .28 and -.59, respectively. The IMSA significantly predicted QoL and also HCU (emergency room visits, hospitalization, outpatient visits, and diagnostic exams) after 3 and 6 months follow-up. Results were comparable between hospital sites, in- and outpatients, and age groups.CONCLUSION: The IMSA is a generic and time-efficient method to assess biopsychosocial complexity and to provide guidance for multidisciplinary care trajectories in adult patients, with good reliability and validity across different cultures.
OBJECTIVE: Ever since Engel's Biopsychosocial Model (1977) emotions, thoughts, beliefs and behaviors are accepted as important factors of health. The Brief Illness Perception Questionnaire (Brief IPQ) assesses these beliefs. Aim of this study was to cross-culturally adapt the Brief IPQ into the Brief IPQ Dutch Language Version (Brief IPQ-DLV), and to assess its face validity, content validity, reproducibility, and concurrent validity. METHODS: Beaton's guideline was used for cross-culturally adaptation. Face and content validity were assessed in 25 patients, 15 physiotherapists and 24 first-grade students. Reproducibility was established in 27 individuals with chronic obstructive pulmonary disease using Cohen's kappa coefficient (K(w)) and the Smallest Detectable Change (SDC). Concurrent validity was assessed in 163 patients visiting 11 different physical therapists. RESULTS: The Brief IPQ-DLV is well understood by patients, health care professionals and first-grade students. Reliability at 1 week for the dimensions Consequences, Concern and Emotional response K(w)>0.70, for the dimensions Personal control, Treatment control, Identity, K(w)<0.70. A time interval of 3 weeks, reliability coefficients were lower for almost all dimensions. SDC was between 2.45 and 3.37 points for individual measurement purposes and between 0.47 and 0.57 points for group evaluative measurement purposes. Concurrent validity showed significant correlations (P<.05) for four out of eight illness perceptions (IPs) dimensions. CONCLUSION: The face and content properties were found to be acceptable. The reproducibility and concurrent validity needs further investigated
The ENCHANT project aims to clarify the differences between circular Calcium Carbonate (CCC) and grounded Calcium Carbonate (GCC), in order to expand the applications of the circular alternative CCC in the paint and coating industry. CCC is produced by pyrolysis from paper waste in an innovative process developed by the company Alucha Works B.V., and it can be applied again as filler or binder in consumer products (e.g. plastics, rubbers, paints and coatings) in a cost-effective manner. Products containing CCC have a higher content of circular resources, which minimizes their carbon footprint, and reduces the exploitation of primary resources. Performances of CCC in oil-based paints, however, is not optimal, due to a larger oil adsorption as compared to GCC. A physical and chemical characterization of CCC and GCC samples, including competitive oil-water adsorption measurements, would help Alucha to formulate a solution to match the properties of CCC and GCC, either adjusting the recycling process or applying a surface modification treatment to CCC. This would enable Alucha to expand the market for CCC, making oil-based formulation products more circular.
Human kind has a major impact on the state of life on Earth, mainly caused by habitat destruction, fragmentation and pollution related to agricultural land use and industrialization. Biodiversity is dominated by insects (~50%). Insects are vital for ecosystems through ecosystem engineering and controlling properties, such as soil formation and nutrient cycling, pollination, and in food webs as prey or controlling predator or parasite. Reducing insect diversity reduces resilience of ecosystems and increases risks of non-performance in soil fertility, pollination and pest suppression. Insects are under threat. Worldwide 41 % of insect species are in decline, 33% species threatened with extinction, and a co-occurring insect biomass loss of 2.5% per year. In Germany, insect biomass in natural areas surrounded by agriculture was reduced by 76% in 27 years. Nature inclusive agriculture and agri-environmental schemes aim to mitigate these kinds of effects. Protection measures need success indicators. Insects are excellent for biodiversity assessments, even with small landscape adaptations. Measuring insect biodiversity however is not easy. We aim to use new automated recognition techniques by machine learning with neural networks, to produce algorithms for fast and insightful insect diversity indexes. Biodiversity can be measured by indicative species (groups). We use three groups: 1) Carabid beetles (are top predators); 2) Moths (relation with host plants); 3) Flying insects (multiple functions in ecosystems, e.g. parasitism). The project wants to design user-friendly farmer/citizen science biodiversity measurements with machine learning, and use these in comparative research in 3 real life cases as proof of concept: 1) effects of agriculture on insects in hedgerows, 2) effects of different commercial crop production systems on insects, 3) effects of flower richness in crops and grassland on insects, all measured with natural reference situations
In het PRIMa mond CARE project wordt onderzocht in hoeverre de mondgezondheid bijdraagt aan de voorspelling van kwetsbaarheid bij thuiswondende ouderen.Doel Het doel van het PRIMa mond CARE project is te onderzoeken in hoeverre mondgezondheid bijdraagt aan de voorspelling van kwetsbaarheid bij thuiswonende ouderen. Resultaten Voor het onderzoek zijn 1202 ouderen geïncludeerd, waarvan 45% mannen. De gemiddelde leeftijd van de participanten was 73 jaar. De eerste resultaten laten verbanden zien tussen kwetsbaarheid en onderstaande gezondheidsfactoren: • het bezoeken van de tandarts voor een spoedconsult; • het ervaren van ongemakken in de mond; • het aanpassen van de voeding als gevolg van ongemakken in de mond en • het dragen van een gebitsprothese. De volgende artikelen over dit onderzoek zijn inmiddels gepubliceerd: 'Probing problems and priorities in oral health among community dwelling elderly in the Netherlands' in het International Journal of Health Sciences and Research. In het International Journal of Health Services is het artikel 'Needs in Sevice Provision for Older People: An comparison Between Greater Manchester (United Kingdom) and Utrecht (the Netherlands)' gepubliceerd. Recentelijk verscheen ‘’Measurement properties of oral health assessments for non-dental professionals in older people: a systematic review’’ in het BMC Geriatrics. Looptijd 01 november 2016 - 01 juli 2020 Aanpak De huisarts brengt met een softwareprogramma genaamd ‘’U-PRIM’’ de groep potentieel kwetsbare ouderen in kaart. De mensen uit deze screening komen in fase twee: U-CARE. Zij ontvangen een vragenlijst: de Groningen Frailty Indicator. Met de uitkomsten van de vragenlijsten worden de domeinen van kwetsbaarheid gedefinieerd. Deze mensen krijgen huisbezoek van een praktijkverpleegkundige die een zorgplan op maat maakt. De verpleegkundige screent tijdens dit bezoek de oudere ook op mondgezondheidsproblemen, naast de algemene gezondheidscontrole. Daarnaast zijn de gegevens uit het tandartsenbestand gekoppeld aan de gegevens van de huisarts. Ook zijn twee vragen over mondgezondheid toegevoegd aan de Groningen Frailty Indicator. Aan de deelnemers van het onderzoek is toestemming gevraagd om de tandartsgegevens op te vragen bij de tandarts en deze te koppelen aan de huisartsgegevens. Daarnaast zijn alle gegevens anoniem verwerkt.
