We assessed all 148 wetland nature reserves in China and the distribution of the four taxa of endemic and threatened terrestrial vertebrates, reptiles, amphibians, birds and mammals. Assessment of the wetland nature reserves was combined with the governmental list of the endemic and threatened vertebrates to identify the richness of the species. Species richness was scored as high, medium or low using a factor analysis method, and 31 wetland ecosystems were marked as high protection areas. The relationship between the threatened species and the endemic species in the reserves was also analyzed. We found that both richness patterns were similar. Based on the richness study, a nature reserve classification system with corresponding.

AIM: This study aims to identify psychological factors against vaccine rejection in Indonesia. The study also provides a review of the group of different factors on psychological factors in social media. METHODS: This study uses secondary data sourced from Facebook, Twitter, YouTube and Instagram about vaccines rejection from 2018 to 2019. That text is labeled based on seven psychological factors that influence vaccine rejection. The factor analysis method is used to determine the relationship between vaccine rejection and psychological factors. RESULTS: Dimension 1 focused on individual and group influences, where the correlation value between factors such as vaccine misinformation, health worker trust, perception of side effect is 0.906 (>0.5). Dimension 2 used different factors such as trust in the goverment, negative opinion about vaccine efficacy, and social influence as contextual/environmental influencers,with a correlation value of 0.866 (>0.5). Meanwhile, Dimension 3 with general perception is a factor in vaccine and vaccination specific problems with a correlation value of 0.940 (>0.5). CONCLUSION: Psychological factors are mainly associated with vaccine rejection. Stakeholders need to observe these factors in identifying conditions for childhood vaccines rejection posted on social media in Indonesia.

Dynamic capabilities are regarded as a strategic premise to creating, maintaining and upgrading sustainable competitiveness. Considering organizational learning as a mediator variable, this study tests the relationship between entrepreneurial capabilities and dynamic capabilities. More specifically, the factor analysis method was employed to verify that dynamic capabilities are comprised of four dimensions, i.e. environmental sensing capabilities, change and renewal capabilities, technological and organizational flexibility capabilities. The research used UMKM in Yogyakarta and Solo as research sample. It was found that entrepreneurial capabilities has a significantly positive effect on dynamic capabilities, while organizational learning, which has significantly positive effect on dynamic capabilities, plays a partial mediating role between the two. These findings indicate that companies can build dynamic capabilities through different levels of organizational learning in the context of innovative and proactive atmosphere. Keywords: Entrepreneurial Capabilities, Organizational Learning, Dynamic Capabilities,

Orchids are one of the most species-rich families in the world, and many species are under threat in numerous countries. Biodiversity research focusing on the relationship between the richness of orchid species and ecological factors was performed across the Cerová vrchovina Mts (Western Carpathians) testing impact of 26 explanatory variables. We aimed to determine the main ecological predictors controlling species richness and to predict potential species richness patterns. Altogether, 19 orchid species were found in the studied area, with Cephalanthera damasonium and Epipactis microphylla being the most common. Four environmental predictors (minimal longitude, carbonate-containing sediments, maximal yearly solar irradiation, and agricultural land) had statistically significant effects on orchid richness following regression analysis. Predictive models for the nine most frequent species using MaxEnt software showed (i) that land cover and geological substrate had the highest contribution to the explained variance in the models and (ii) strong potential for occurrence of given orchids in several poorly mapped parts of the studied area.

At the present stage of investigative activities modernization, there is a need to improve the methodological support of pre-trial investigation of criminal offenses. The investigating authorities of the pre-trial investigation of the National Police of Ukraine have a large number of methods in their arsenal; however, there are methods that have not found a theoretical and methodological justification and description. Among these methods the method of factual analysis it should be highlighted. The author considers the factual analysis as a method of extracting facts (or individual elements, parts, parts of factual data) from an array of criminal offense data for their further aggregation (holistic association) and establishing the degree of evidence. The article deals with an algorithm for applying the method of factual analysis during the pre-trial investigation of criminal offenses. It is determined the main tasks and the main conditions for their quality solution at the preparatory, main and final stages of the implementation of the method. It is noted that in the general context, the algorithm for the implementation of the method of methodological analysis occurs in five interrelated areas of activity of subjects of pre-trial investigation, namely: search-forming, primary factor analysis, program and factographic, presentation and secondary factor analysis. It is noted that during the pre-trial investigation of a criminal offense, the application of the method of factual analysis will allow: 1) to clarify the components (parts, segments, elements) of the actual data due to the multidimensional presentation of logical connections; 2) to identify the components (parts, segments, elements) associated with a criminal offense; 3) to identify the relationship between the components (parts, segments, elements) of the actual data; 4) to identify various non-obvious (hidden) connections and graphically interpret the degree of intensity of these connections; 5) to investigate the internal structure of the components (parts, parts, elements) of the actual data; 6) graphically represent the relationship between the various components (parts, segments, elements) of the actual data; 7) conduct multidimensional comparisons of components (parts, parts, elements) – from two to four; 8) to identify the relationships of individual factors that have causal relationships; 9) to systematize a large array of data and their components (parts, parts, elements), etc. Therefore, the expected results from the process of applying the method of factual analysis is that it will contribute to the factual proof that the available body of evidence about the facts and circumstances of the criminal offense are appropriate, permissible and reliable evidence; interconnected and sufficient to make an appropriate procedural decision.

The vegetation of inland plains and hills of the Andrew’s Field and Tsaba-Tsaba Nature Reserve, Bredasdorp District, Western Cape was classified using TWINSPAN and Braun-Blanquet procedures. The resulting four plant communities and nine subcommunities were described and interpreted ecologically. The vegetation was sampled using 97 randomly stratified plots. The floristic composition, Braun-Blanquet cover-abundance of each species, and various environmental variables were recorded in each sample plot. The relationship between the vegetation units and the associated environmental gradients was confirmed by ordination, using the DECORANA computer program, applied to the floristic data set. The conservation priority of each vegetation unit was determined by taking the occurrence of Red Data List species, limestone endemic species and Cape Floristic Region endemic species into consideration. TTie distribution of the plant communities can mainly be ascribed to differences in the clay/sand content of the soil and the degree of exposure of the vegetation to the dominating winds (southeastern and northwestern) of the area.

Explaining species richness patterns over broad geographic scales is a central issue of biogeography and macroecology. In this study, we took spatial autocorrelation into account and used terrestrial vertebrate species richness data from 211 nature reserves, together with climatic and topographical variables and reserve area, to explain terrestrial vertebrate species richness patterns in China and to test two climatically based hypotheses for animals. Our results demonstrated that species richness patterns of different terrestrial vertebrate taxa were predicted by the environmental variables used, in a decreasing order, as reptiles (56.5%), followed by amphibians (51.8%), mammals (42%), and birds (19%). The endothermic vertebrates (mammals and birds) were closely correlated with net primary productivity (NPP), which supports the productivity hypothesis, whereas the ectothermic vertebrates (amphibians and reptiles) were strongly associated with both water and energy variables but weakly with NPP, which supports the physiologically based ambient climate hypothesis. The differences in the dependence of endothermic and ectothermic vertebrates on productivity or ambient climate may be due in part to their different thermoregulatory mechanisms. Consistent with earlier studies, mammals were strongly and positively related to geomorphologic heterogeneity, measured by elevation range, implying that the protection of mountains may be especially important in conserving mammalian diversity.

Demotivation can negatively influence the learner’s attitudes and behaviors, and result in negative learning outcomes. This paper investigates factors contributing to demotivation in learning Japanese as a foreign language in Indonesia, and the relationship between demotivating factors and present proficiencies. A seventeen-item questionnaire was completed by 157 Indonesian university students. As the result of exploratory factor analysis, questionnaire items consequently grouped to four categories: Course difficulty, Speaking anxiety, Devalued learning, and Boredom.The validity of the four-factor structure was verified by the confirmatory factor analysis method. In addition, two-way ANOVA was performed to investigate the relationship between demotivational factors and proficiency level. As a result, statistically significant differences were found between Low and High groups in all the factors, and between Middle and High groups in the factors expect for Devalued learning. In addition, the scores of Speaking anxiety and Boredom consistently scored the highest among the four factors. However, the degree of demotivation was decreased as the learners’ Japanese proficiency improved. Findings from this study indicated that teachers should strive to make classes not only less anxious but also more interesting. Moreover, teachers should scaffold learners, especially low proficient beginners to prevent or minimize their demotivation.

The concept of entrepreneurial orientation, which emerges with the development of strategic management, refers to entrepreneurship orientations of businesses. The businesses need resources in other words organizational slack in order to develop their entrepreneurial trends. The organizational slack consists of three slack type. These slack types are available slack, recoverable slack and potential slack. The purpose of this study is to examine whether organizational slack in the businesses has an effect on entrepreneurial orientation. The relationship between organizational slack and entrepreneurial orientation was investigated through 20 companies that were traded in Borsa Istanbul Corporate Governance Index for 2010-2014 period using panel data analysis method. The results of the study indicate the existence of a statistically significant relationship between and the available slack and the recoverable slack with the entrepreneurial orientation in the businesses. According to findings; there was no statistically significant relationship between potential slack and entrepreneurial orientation.
