“…Once the ideal cluster solution was determined according to the criteria set out by Hair et al [ 58 ], the profiles of the different groups were determined, using all those variables not included in the cluster analysis. Chi-square tests, calculating the value of the Contingency Coefficient (C 2 ) to verify the size effect and the intensity of the association between the qualitative variables compared the results through the performance of the ANOVA test for the continuous variables and for the qualitative variables [ 61 ]. The significance level was established at a value of p ≤ 0.05.…”

The current COVID-19 pandemic has paralysed whole countries, which have had to confine their entire population and this changed people’s lives worldwide. The aim of this study is to identify the reasons for and the level of commitment to physical activity among the Spanish population during confinement and the return to the “new normal”. A sample of 1025 amateurs, 534 males and 491 females with an average age of 35 years old were interviewed using an online survey that collected their motives for practising sport and their commitment to physical activity. A cluster analysis combining hierarchical and non-hierarchical methods was performed, identifying three groups of amateurs: High Commitment (n = 650), Moderate Commitment (n = 324), and Low Commitment (n = 81). The main motives shown by the different groups were psychological motives related to an improved or managed general or emotional well-being. Regarding commitment, all the groups showed higher scores in enthusiasm for physical activity than affliction from sport. The variables referring to gender, educational level and sports habits showed differences that enabled the identification of the different groups. These findings highlight the importance of conducting segmentation studies that provide specific population profiles to improve the action strategies of governments and specialists.

“…Differences in the adjusted days of MVPA between disability groups and with no disabilities were tested. A conversion of standard deviation of the adjusted mean number of days was used by the 95% confidence intervals to then be used to measure effect sizes from Cohen’s d. Measurement of effect sizes through differences of means were used to determine the practical significance in addition to the p -values given from the statistical significance [40]. Interpretations of these effect sizes were based on Cohen’s d interpretation that values between 0.20–0.49 were small, 0.50–0.79 were medium and over 0.80 were large [41].…”

Evidence suggests that adolescent males take part in more moderate-to-vigorous physical activity (MVPA) than females, and that adolescents with disabilities participate in even less. Public health data are typically based on the international physical activity (PA) recommendations of at least 60 minutes of MVPA daily. However, it appears that data are lost because a person who reports MVPA 0–6 days a week is grouped together and is considered as ‘inactive’. Therefore, the purposes of this study were to report differences among adolescents with and without disabilities who were ‘active’ and ‘inactive’ and to explore differences by sex. A complete enumeration study (2017 School Health Promotion Survey; n = 128,803) of Finnish adolescents aged between 14–19 years old was conducted. The single item self-report MVPA was used with items from the Washington Group on Disability Statistics. Data were grouped into physiological and cognitive disabilities and were split into active and inactive adolescents based on the PA recommendations; subsequently, binary logistic regression analyses were performed. Data from the inactive participants were analyzed with multivariate analysis of covariance and effect sizes were reported. Approximately 10% of males and 17% of females reported disabilities. There were fewer adolescents with disabilities who took part in daily PA (OR = 0.90, CI = 0.85–0.94), especially among those with cognitive disabilities (OR = 0.86, CI = 0.82–0.91). There were more active male than female adolescents (OR = 1.48, CI = 1.43–1.52). Of the inactive adolescents, females reported similar MVPA to males, with and without disabilities after controlling for age, school type, and family financial situation. Inactive adolescents with walking difficulties reported the least amount of MVPA (males; mean = 2.24, CI = 2.03–2.44, females; mean = 2.18, CI = 1.99–2.37). The difference in means with adolescents without disabilities according to Cohen’s d effect size was medium for males (0.56) and females (0.58). The effect sizes from all other groups of disabilities were small. The difference in PA between males and females has diminished among the inactive groups, yet there is still a need to improve the gap between males and females, especially for those who meet the PA recommendations. More strategies are needed to improve MVPA among adolescents with disabilities, especially those with cognitive disabilities.

“…However, this statistical test is used to interpret what local communities view on conservation, and this is not just to accept or reject null hypothesis (Peeters 2016). In addition, sample size is also relatively large (Khalilzadeh and Tasci 2017). In this study, a p-value greater than 0.05 but less than 0.1 is considered important or has some significant influence on conservation supports by local communities.…”

Sudrajat J, Sawerah S, Permatasari N, Suharyani A, Karmoni A, Anshari GZ, Wardhana D, Rossanda D. 2018. People’s viewstowards Gunung Palung National Park, West Kalimantan, Indonesia. Biodiversitas 19: 1138-1146. It is a common belief that themanagement of national park prevents local communities from accessing the park and using the park resources. Illegal logging and otherunwanted encroachments to the park become a big problem, as national park authority has a limited capacity to monitor the whole park.This research aimed to study how local communities viewed Gunung Palung National Park, which is located in Ketapang and KayongUtara District, West Kalimantan Province, Indonesia. A total of 91 respondents from seven villages were interviewed. In general, about70% of respondents viewed the importance of economic benefits, resulting from limited access to traditional gardens in the use zone ofthe park and the supply of clean water. Approximately 67% of these respondents viewed the protection of natural resources in the parkwas not important. This view was possibly due to their little knowledge of the park management and the use of zoning system in thepark. It was reported that park officers have some activities, but the collaboration and relationship between park officers and localcommunities need more time to mature. It seems that the poor and the youth tend to exploit more and put higher pressures on the parkthan the elderly groups.
