... expert judges' evaluation of the relevance and wording of the proposed dimensions can be observed in Table 3. The quantitative evaluation by the expert judges can be observed in Table 4. The items were validated in terms of relevance, obtaining values higher than the minimum established in the coefficient used (Aiken's V > 0.75; VI > 0.50). ...Citations
... Good reliability (Cronbach's alpha ¼ 0.8553), high levels of participant satisfaction, and high levels of understanding of the procedures and materials were all identified in the pilot method. The instrument is valid for measuring people's attitudes and knowledge about sustainable energy and renewable energy [27]. ...
... Through the different sections, socio-demographic information was gathered together with that referring to culinary and gastronomic practices prior and during the lockdown due to COVID-19 [17]. Similarly to the studies by Acosta-Banda et al. [40] or Napitupulu [41], in other fields, this initial questionnaire was qualitatively validated by the five members of the research team and other colleagues from the nutrition and gastronomy departments of the University of Alicante, who evaluated whether the indicators adequately covered the concepts described in the information objectives. ...
Introduction:
The third wave of COVID-19 had a large impact on the autonomous Region of Valencia, which gave rise to restrictions on movement and access to collective eating establishments. The objective of this study is to analyse the culinary and gastronomic behaviour exhibited by the population of the province of Alicante during the period of restrictions, in early 2021, in order to compare the results with an identical survey carried out during the first lockdown of 2020.
Methods:
observational and repeated cross-sectional study.
Results:
The frequency and time dedicated to cooking were similar, as was the tendency to cook as a family, although the percentage of meals ate alone increased and the presence of audiovisual devices during meals persisted. Recipes, cookbooks, websites and online courses became the principal sources of learning and the self-perception of improvements in culinary skills was greater. The cooking of traditional dishes of the Mediterranean diet predominated to the detriment of ready meals, but 41.6% of those surveyed preferred to improvise. The recipes most consulted were those for main courses.
Conclusions:
In spite of certain changes and setbacks, which in many cases led to a regression to the situation prior to the pandemic, many of the improvements made during the lockdown of 2020 persisted. Changes were made in culinary and gastronomic practices that can help to achieve a more conscious, healthy and sustainable diet but which require educational policies and actions to reinforce and consolidate them.
... The first phase develops the instrument items based on literature reviews and pre-existing instruments. The second involves the expert panel, and the third is the psychometric analysis(Acosta- Banda et al., 2021;Morgado et al., 2017). ...
... Expert judgement determines the validity of the content. In an expert review, some grammatical and spelling issues, as well as the correction of some answer descriptors, were fixed to improve the instrument's quality (Acosta-Banda et al., 2021). The content validity is assessed based on how well the instrument content represents the overall subject, and the knowledge level (aspects) will be measured. ...
... The content validity was determined using the content validity index (CVI) with a 4-point rating system of relevance level (from 1 = irrelevant and 4 = highly relevant), then re-recorded as 1 (relevance scale 3 or 4) and 0 (relevance scale 1 or 2). The CVI (I-CVI) judgement of the item is calculated as the number of experts giving the relevant rating divided by the total number of experts; the I-CVI is not lower than 0.78 (Yusoff, 2019) or 0.75 (Acosta-Banda et al., 2021). In this study, the instrument was approved after the experts' revision process. ...
Background: The visual analogue scale (VAS) instrument is proven to be reliable in measuring anxiety. Experts argue, however, that measuring the aspect of psychosocial trauma in a different language has limitations, especially among hospitalised children under the age of six. As a result, the study sought to revise and validate a trustworthy, child-friendly VAS for use in Indonesia. Methods: A preliminary survey was conducted among 81 respondents that met the inclusion criteria. An expert committee reviewed and revised the VAS-Anxiety-Indonesia for sensitivity and content validity. Thus, the Centre of Indonesia Language was charged with forward and backward translation from English to Indonesian and vice versa. In this study, data were collected in two phases. The first was the preliminary data collection from 21 respondents for face and content validity. The second phase recruited 60 respondents with retests and confirmations of modified items and components of VAS-A-Indonesia. Statistical analysis used a Pearson correlation coefficient of 0.05. The second test performed the content validity index, item correlation analysis, internal consistency for reliability testing, and Exploratory Factor Analysis. Results: The instrument consists of 12 items. With three factors to measure anxiety, they accounted for 65.2% of the overall variance. The content validity index was 0.825 (Aiken's V), item correlations ranged from 0.354 to 0.686, and Cronbach's alpha was 0.837. Conclusion: The Indonesian version of the VAS-A was a valid and reliable instrument for assessing the anxiety of preschoolers admitted to hospitals.
... Policy analysis in the WE nexus aims to identify strategic opportunities for linking decision-making processes and ultimately realizing higher resource-use efficiencies [25]. Individual perceptions, awareness, habits, and supports toward WE policies [26,27]; policymakers' response to public opinions [28]; and the participation of industrial sector [29] are all critical to managing WE resources in a more efficient and equitable manner. Due to quantitative methods that take resources interlinkages at an urban scale as a basis to identify strategic organizational linkages are largely absent in existing literature. ...
Urbanization in developing countries has imposed great pressure on the availability of water and energy (WE) resources, while single-sector strategies may cause several unanticipated consequences. To find sustainable solutions for resource management, this study develops an integrated approach to assess urban WE from a nexus perspective. With the city Shenzhen as a case study, the existing WE nexus on the supply and demand sides of urban areas is first quantified. Subsequently, a system dynamics model (SDM) is constructed to reveal the complex interactions in the urban nexus, and the trends of WE supply and demand by 2035 are simulated. To narrow the potential resources gap, a policy analysis considering the interest and influence of various stakeholders is conducted to formulate policy scenarios. As revealed from the results, the resources gap will expand continuously by 2035, especially for water resources. Compared to the demand side, the policies implemented on the supply side exhibit a better performance, and the scenario of import expansion could independently achieve the desirable result. Moreover, as the demand side displayed more complexities, the implementation of future policies should rigorously weigh the priorities and difficulties of a range of stakeholders’ involvements.
... A value of 1 is calculated when all experts choose the highest possible rating [75]. Values greater than 0.75 are in general accepted [76]. Finally, in order to assess content validity for the overall WF management construct, the average scale-CVI (S-CVI) was used, which is computed as the average of all items' CVI. ...
Common problems when carrying out water footprint (WF) assessments are obtaining specific primary data, dealing with the complexity of its computation, and the availability of quality data. In a supply chain context, inconsistencies are even more exacerbated. In order to fill in this research gap, this study proposes and evaluates the content validity of a survey scale to assess WF management initiatives implemented by companies, with a focus on supply chains and the agriculture industry. In order to do so, a literature review was performed to identify candidate survey items whose content was later validated with experts in terms of their relevance, clarity, and essentiality to measure WF management. Content validity was assessed using several indices (items’ content validity index (I-CVI), Kappa’s coefficient, Aiken’ V coefficient, and content validity ratio (CVR)), which indicated high content validity for the selected items. This study provides a set of measurement survey items that can be used to evaluate WF management initiatives implemented in agri-food supply chains in future empirical studies.
This study assesses the implementation of socioformation in Public Higher Education Institutions (HEIs) in Mexico, exploring its impact on the quality of education in the knowledge society. With a sample of 150 educators, gender-balanced (44.7% female, 55.3% male), and an average age of 43.7 years, the research employed a validated socioformative rubric. Significant progress was observed in analytical and creative thinking, while areas related to living conditions and entrepreneurship education showed slower development. The findings highlight the advancements in socioformation but advocate for further research, including classroom observation and student evidence collection. Gender differences, communication, and leadership emerged as critical factors influencing socioformation implementation. Women demonstrated deeper comprehension of the educational model, willingness to adopt innovative strategies, and emphasis on socioformation axes. As educators gain experience, their adaptability to new pedagogical approaches increases. The study underscores the universal relevance of effective communication, leadership, and stakeholder involvement in successful educational model implementation. The research contributes valuable insights, emphasizing the importance of openness to new approaches and collaboration to prepare students for the challenges of the evolving knowledge society.
This article focuses on the multi-generational social analysis of a region in Mexico that represents an important energy cluster. In general, social participation in energy sector projects needs to be strengthened to increase regional competitiveness. Data collection was carried out through a representative sample survey. Important findings on social confidence and energy poverty were obtained, which serve as a starting point for the design of new competitiveness initiatives for the energy cluster.
Increasing the use of biofuels to reduce pollution is an effort in many countries. An alternative that is starting to be marketed internationally, which reduces greenhouse gas emissions and applies circular economy for its production is second-generation bioethanol (E2G); however, in Peru there are no policies for its commercialization in the current gasohol blend. This study will determine consumer's willingness to pay (WTP) for E2G by applying surveys using the double-bounded dichotomous choice contingent valuation method (CVM). A total of 472 consumers of premium and regular gasohol in Metropolitan Lima were asked about their WTP for E2G, demographic characteristics, vehicle usage and level of perception related to the environment. It was found that users of premium and regular gasohol would be willing to pay a premium of 10.40% and 7.03% respectively. Likewise, it was obtained that people who have a higher perceived consumer effectiveness (PCE) are more likely to pay a premium for E2G.
La Formación Profesional para el Empleo (FPE) se define como aquella que responde a las necesidades del mercado laboral y se orienta a la adquisición, mejora y actualización continua de las competencias y cualificaciones profesionales, favoreciendo la formación a lo largo de toda la vida. Su finalidad es impulsar el desarrollo personal y profesional de las personas trabajadoras (ocupadas y desempleadas), al tiempo que promueve su empleabilidad. Considerando lo anterior, se presenta un estudio que responde al objetivo de determinar el conocimiento que poseen las empresas acerca de la oferta de formación profesional y los mecanismos que permiten su transferencia al puesto de trabajo. La metodología empleada es de corte cuantitativo, utilizando el cuestionario como instrumento de recogida de información (n= 331 empresas). Los resultados confirman, por un lado, el desconocimiento de las empresas acerca del funcionamiento, beneficios y oportunidades que ofrece la formación para el empleo, y por otro, la elevada valoración de las competencias de tipo transversal en la formación de los trabajadores/as, destacando su importancia para el diseño de los actuales planes de formación. Se concluye señalando la necesidad de una mayor difusión de las políticas activas de empleo centradas en la oferta de formación, así como la pertinencia de introducir las competencias transversales en su planificación.
