The importance of MERISE for structuring and analyzing data is underlined, as it enables the measurement of the adequacy between training and the needs of the labor market. The innovation of the study lies in the adaptation of the MERISE model to the local context, the development of innovative indicators, and the integration of a participatory approach including all relevant stakeholders. Contextual adaptation and local innovation: The study suggests adapting MERISE to the specific context of the Republic of Congo, considering the local particularities of the labor market. Development of innovative indicators and new measurement tools: It proposes creating indicators to assess skills matching and employer satisfaction, which are crucial for evaluating the effectiveness of vocational training. Participatory approach and inclusion of stakeholders: The study emphasizes actively involving training centers, employers, and recruitment agencies in the evaluation process. This participatory approach ensures that the perspectives of all stakeholders are considered, leading to more relevant and practical outcomes. Using the MERISE model allows for: • Rigorous data structuring, organization, and standardization: Clearly defining entities and relationships facilitates data organization and standardization, crucial for effective data analysis. • Facilitation of monitoring, analysis, and relevant indicators: Developing both quantitative and qualitative indicators helps measure the effectiveness of training in relation to the labor market, allowing for a comprehensive evaluation. • Improved communication and common language: By providing a common language for different stakeholders, MERISE enhances communication and collaboration, ensuring that all parties have a shared understanding. The study’s approach and contribution to existing research lie in: • Structured theoretical and practical framework and holistic approach: The study offers a structured framework for data collection and analysis, covering both quantitative and qualitative aspects, thus providing a comprehensive view of the training system. • Reproducible methodology and international comparison: The proposed methodology can be replicated in other contexts, facilitating international comparison and the adoption of best practices. • Extension of knowledge and new perspective: By integrating a participatory approach and developing indicators adapted to local needs, the study extends existing research and offers new perspectives on vocational training evaluation.展开更多

Using factor analysis,we derive that the model includes three factors: skill literacy,relationship literacy and basic literacy. The weights of each factor are 0. 580,0. 244 and 0. 174 8,respectively. Skill literacy is affected by skill level,learning ability,career aspiration,ability to analyze problems,physical health status and other factors. Relationship literacy is affected by the sense of teamwork,interpersonal skills,social support and other factors. Basic literacy is affected by educational level,hardworking spirit and other factors. According to the results,we put forth the following recommendations to improve the new generation migrant workers' employability: strengthening the vocational skill training; coordinating the vocational education resources.展开更多

However, learning therapist skills is a sensitive process that will be affected by the processes which occur within the group. Objective: The aim was to examine prospective psychotherapists’ attitudes to group assessments based on the revised version of the Cognitive Therapy Scale (CTS-R). Method: Participants were 56 students with an average age of 45.65 years (range = 31 - 64). They were recruited from psychotherapy training at the Gothenburg University and the Evidens University College in Sweden. A questionnaire was constructed in which the questions were answered by check on visual analogue scales (VAS). Results: A majority of students consisting of 38 participants (68%) had a very positive approach to group assessments, while a minority of 18 participants (32%) was more negative. Most crucial for how to answer the question of group assessments was whether they considered themselves as fairly evaluated by their student colleagues within the group and whether or not only the supervisor should make the assessments. The view of group assessments (negative or positive) was not related to age, gender, and level of education in CBT or profession. In addition, both groups had a very positive view of both the CTS-R and the supervisors. Conclusion: It was concluded that more studies with the same focus are needed to determine the extent to which the results are generalizable.展开更多

Valuation of ecosystem services is favorable for people realizing the importance of natural ecosystem to human being, and considering its long-term influence on sustainable development of human society when making decisions. Besides, it is an attempt of ecology, geography and other natural sciences to influence social decision process by economic methods. The Value of the World's Ecosystem Services and Natural Capital, written by Robert Costanza et al., in 1997, is generally regarded as a masterpiece for the research of valuing ecosystem services. However, the classifying standard of ecosystem services, the method of various services summation and the purpose for static global value, had confronted many criticisms. Still to now, accurately valuing ecosystem services is not easy, because of the complexity of natural ecosystem, the weak capability of economic system to pricing ecosystem services and the lack of more study in this field. Based on the criticisms summarizing and comprehensive analysis, further study suggestions of ecosystem services valuation is presented: multi-scale integrated and community participation applied in evaluation, dynamic changes of material value and intangible value of ecosystem services, investigation and simulation studies of the marginal value when ecosystem services changed, associated with related areas like ecological compensation research, and research on the market-oriented evaluation of ecosystem's intangible values.展开更多

First, the alternativesunder each risk state are rated using linguistic terms, and' thelinguistic decision matrix is constructed. Secondly, thelinguistic terms are transformed into triangular fuzzy numbers,so that the linguistic evaluations can be changed into numericalforms. Thirdly, with the aid of the prospect theory, theprobability weight functions and the linguistic value functionscan be computed, based on which the prospective values of thealternatives are obtained. Finally, the alternatives are rankedwith respect to the prospective values combined of probabilityweight and linguistic value functions. Thus, the optimalchoice is made. The decision process takes the psychologicalpreferences of the decision maker into consideration.

Furthermore, the day to day variability of gastric emptying for solids should be assessed. Methods 13 C octanoic breath tests were performed in 15 type 1 diabetic subjects on two separate days within one week. The influence of metabolic control on gastric emptying was prospectively examined over a mean of 8 months in 14 patients with newly diagnosed type 1 diabetes and 44 long term diabetic patients (type 1: n=31; type 2: n=13).Patients with longterm diabetes were stratified according to their HbA 1c at follow up (group 1: HbA 1c U7.5%, n=17; group 2 HbA 1c >7.5%, n=27). 13 C octanoic breath tests were sampled with an isotope selective non dispersive infrared spectrometer. The gastric emptying parameters were calculated using nonlinear regression analysis of the time course of 13 CO 2 exhalation:half emptying time (t 1/2 ) and lag phase (t lag ). Results The intraindividuell coefficient of variation was 17.8% for t 1/2 , and 28.2% for t lag . Mean t 1/2 and t lag in newly diagnosed type 1 diabetics were normal at baseline and were significantly increased at follow up. In patients with longterm diabetes, gastric emptying was unchanged during follow up. Gastric emptying was significant delayed in group 2 compared with group 1 at baseline and follow up respectively. There was a significant correlation between HbA 1c and t 1/2 , t lag at follow up. Conclusions 13 C octanoic breath test has a relatively good reproducibility in patients with type 1 diabetes. Gastric emptying times are already significantly increased after few months in newly diagnosed type 1 diabetes. There is a more pronounced delay of gastric emptying in longterm diabetic subjects with poor compared to patients with good metabolic control.展开更多
