Informational Barriers

Even with significant breakthroughs in the production and delivery of meteorological information, most farmers are not able to utilize such information properly and pertinently. Up to the present time, a standardized scale has not been developed to examine farmers’ sustainability barriers to meteorological information use (BMIU). Furthermore, there is no doubt that identifying indicators and dimensions of sustainability barriers to meteorological information and weather forecasts’ usage by farmers can play a major role in their adaptation and resilience to the risks of climate change. Therefore, the present study aimed to generate and validate a scale for BMIU by farmers through an eight-step approach. Accordingly, the statistical population included 9006 Iranian farmers, 368 of whom were selected as study samples. The principal component factor analysis (PCFA) and second-order confirmatory factor analysis (CFA) were further practiced to develop the scale for meteorological information and weather forecasts’ use. Factor analysis also led to the emergence of five latent factors including “educational–communicative barriers (ECBs)”, “normative barriers (NBs)”, “informational barriers (IBs)”, “infrastructural–political barriers (IPBs)”, and “professional–economic barriers (PEBs)”. The second-order CFA correspondingly confirmed these five factors and their 25 related indicators. Given the challenges facing academic scholars, decision makers, and authorities in the application and facilitation of meteorological information, the developed multidimensional scale in this study along with its implementation steps can be effective in examining the limitations of utilizing such information and measuring its impacts in different agricultural communities.

Metacognitive Beliefs

Metacognition is a higher-level cognition of identifying one’s own mental status, beliefs, and intentions. This research comprised a survey of 184 people with schizophrenia to verify the reliability of the metacognitive rating scale (MCRS) with the revised and supplemented metacognitions questionnaire (MCQ) to measure the dysfunctional metacognitive beliefs of people with schizophrenia by adding the concepts of anger and anxiety. This study analyzed the data using principal component analysis and the varimax method for exploratory factor analysis. To examine the reliability of the extracted factors, Cronbach’s α was used. According to the results, reliability was ensured for five factors: positive beliefs about worry, negative beliefs about uncontrollability and danger of worry, cognitive confidence, need for control, and cognitive self-consciousness. The negative beliefs about uncontrollability and danger of worry and the need for control on anger expression, which were both added in this research, exhibited the highest correlation (r = 0.727). The results suggest that the MCRS is a reliable tool to measure the metacognition of people with schizophrenia.

The construct validity and reliability of the 1987 Perceived Physical Competence Scale of Lintunen were examined to assess the applicability of the instrument for use with adolescents with disabilities. Subjects were 51 girls and 34 boys ( M age = 15.1 yr.) from several schools in central Finland. Principal component factor analysis with varimax rotation yielded the same two factors for adolescents with disabilities as reported for nondisabled adolescents in the related literature. Cronbach alphas for the two factors were .89 and .56. It was concluded that the scale is an appropriate measure for adolescents with disabilities. Statistical analysis indicated no gender differences for adolescents with disabilities. When compared with nondisabled groups in the related literature, these adolescents had perceived fitness similar to nondisabled peers but significantly lower than that of athletes without disabilities.

The purpose of this study is to develop a reliable and valid measurement tool to explore views about organisational justice in schools and to examine teachers' and school administrators' views about organisational justice in primary schools. The sample of the study consisted of a total of 455 participants, 176 school administrators and 279 teachers from the primary schools in the Centre of Van. The Organisational Justice Scale, developed by the authors, was employed as data gathering tool. Principal Component Factor Analysis was used to determine the content and construct validities of the scale and Confirmatory Factor Analysis was employed to evaluate the obtained results. As a result of the study, the developed Organisational Justice Scale (OJS) was found to be a valid and reliable measurement tool for school applications.

The incidence of clinically apparent asymmetric profiles of neuropsychological deficits in Alzheimer's disease (AD) patients similar to those reported in the PET literature is currently unclear. This study investigated lateral neuropsychological asymmetry using principal component factor analysis in a sample of 153 patients diagnosed with probable AD. Using factor scores, patients were classified into groups exhibiting asymmetric or symmetric profiles of neuropsychological deficits. In the analysis of lateral asymmetry, 27.5% of patients were classified as asymmetric (10% verbally and 17% visuospatially). Consistent with reports of continued asymmetry beyond the mild dementia stage, asymmetry was exhibited in the mild, moderate, and severely demented groups. These findings of neuropsychological asymmetry across stages of dementia are consistent with the picture of significant neuropsychological heterogeneity in AD that has been emerging in the decade.

One hundred and fifty-two grandparents who had experienced the death of a grandchild in the preceding three years or so served as subjects for two separate but related studies investigating the multidimensional nature of the grief reactions of grandparents. In Study 1, subjects responded to an open-ended questionnaire which asked for brief descriptions of their grief reactions immediately following the death of the grandchild, and perceived changes in their affective and behavioral responses with the passage of time. A principal component factor analysis procedure was used to identify the major dimensions in the grief reactions of grandparents. Of the six factors that emerged, Factor 1 (Emotional Rupturing) and Factor 2 (Survivor Guilt) accounted for 21.0 percent and 18.6 percent, respectively, of the total variance. In Study 2, a six-month longitudinal follow-up of seventeen grandparents was conducted by means of in-depth interviews. Subjects provided detailed personal accounts of their coping and recovery processes. Interview data were analyzed using a qualitative approach. The results of Study 2 corroborated and supported the factor analysis results obtained in Study 1. Both studies highlight the continuing need for gerontologists to investigate the complexity of grandparents' grief reactions. The studies draw attention to the mental health implications for older adults who have experienced loss and bereavement.

Background and Purpose: This study was done to develop and psychometrically test the Collaboration in the Clinical Learning Environment (CCLE) tool. The researcher acknowledged 2 distinct populations that required input into this particular tool development: staff nurses and nursing faculty members. Both have influence into student learning. Methods: Research followed the 8-step methodology for tool development as defined by DeVellis. Results: Reliability testing was done on the 24-item CCLE, which confirmed a Cronbach’s alpha of .96. Exploratory factor analysis with principal component factor analysis was done to examine the structure of the instrument. Validity was supported through the content expert review, along with concurrent validity. Conclusions: Although collaboration has been emphasized for many years in the clinical learning environment, the construct has never been successfully operationalized. Implications for nursing education, practice, and theory are discussed.

Strong Orientation

This study presents a tourist ecological orientation (TEO) construct based on the responses of participants who were asked to state the importance of various ecological features of planned tourist sites. The higher the TEO score, the more sensitive the person's attitudes toward the ecological requirements and responsibilities of tourist sites. A principal component factor analysis reveals two alternative dimensions of the TEO concept: ‘destination oriented’ and ‘visitor oriented’. The higher score that was given to the latter dimension supports the argument that successful implementation of ecological values at tourist sites requires a strong orientation towards consumer needs in addition to an ideological commitment to the environment. In addition, differences in ecological orientation patterns and structure were analysed along age and nationality.

OBJECTIVES: To assess the factors that influences the participation and engagement of dental students in online classes. METHODOLOGY: A descriptive cross-sectional study was conducted using a pre-validated questionnaire with 45 barriers items used. The Cronbach Alpha value after removing certain items in our study was calculated to be 0.934, which resulted in 35 barrier items. Recorded data were coded and entered using SPSS version 23.0. Nominal data were presented as frequency and percentage, whereas all numerical data was entered as mean and standard deviation. Factor analysis on questions pertaining to barriers to e-learning was done. RESULTS: The underlying construct of the data was identified using principal component factor analysis. The type of rotation used was Varimax. The value of Kaiser-Meyer-Olkin measure for sampling adequacy (MSA) was 0.880. The criteria used for identifying factors were the latent root criteria. A total of six factors were identified. The overall variance explained by these factors was 61.9%. The barriers ranked the highest were those pertaining to motivational problems and time interruptions (2.8667±0.88524). The barriers that were ranked the lowest were those pertaining to instructors and personal problems (2.3894±0.81059). CONCLUSION: The biggest barrier was found to be motivational problems in attending online classes. The second-highest ranked barrier was social problems. The third barrier included a lack of support services. Technical barriers were ranked fourth. The barrier that was ranked fifth was a lack of pre-requisite skills. The barriers that were reported to be the least were problems pertaining to the instructor and personal problems.
