Mounting environmental issues have prompted reconsideration of the human–nature relationship. Accordingly, attitudes to nature, as an important dimension of human–nature interactions, have become a research focus. How feelings and attitudes towards nature are influenced by evolutionary and social-cultural constructions, and whether there is variation between different cultural groups, demands more attention. Using a survey of visitors to two very different National Parks, the New Forest National Park, England and Jiuzhaigou Scenic Area, China, this paper shows that of nationality and living environment, differences between the two nationalities were significant in respect of both attitudes and feelings. Specifically, it demonstrates that the biophilia thesis, which purports that people have an innate and a genetically inherited need for affiliation with nature, is influenced by their socio-cultural environment, in particular their national culture, but also by their current living place. The study contributes to our understanding of sustainable tourism in natural areas.  相似文献

Aims: To better understand the impact of the clinical course of multiple sclerosis (MS) and disability on employment, absenteeism, and related factors.

Materials and methods: This study included respondents to the North American Research Committee on Multiple Sclerosis Registry spring 2015 update survey who were US or Canadian residents, aged 18–65 years and reported having relapsing-remitting MS (RRMS), secondary progressive MS (SPMS), or primary progressive MS (PPMS). The RRMS and SPMS participants were combined to form the relapsing-onset MS (RMS) group and compared with the PPMS group regarding employment status, absenteeism, and disability. Multivariable logistic regression was used to examine the relationship between employment-related outcomes and factors that may affect these relationships.

Results: Of the 8004 survey respondents, 5887 (73.6%) were 18–65 years of age. The PPMS group (n?=?344) had a higher proportion of males and older mean age at the time of the survey and at time of diagnosis than the RMS group (n?=?4829). Female sex, age, age at diagnosis, cognitive and hand function impairment, fatigue, higher disability levels, ≥3 comorbidities, and a diagnosis of PPMS were associated with not working. After adjustment for disability, the employed PPMS sub-group reported similar levels of absenteeism to the employed RMS sub-group.

Limitations: Limitations of the study include self-report of information and the possibility that participants may not fully represent the working-age MS population.

Conclusions: In MS, employment status and absenteeism are negatively affected by disability, cognitive impairment, and fatigue. These findings underscore the need for therapies that prevent disability progression and other symptoms that negatively affect productivity in persons with MS to enable them to persist in the workforce.  相似文献

The purpose of this study was to develop a systematic process that other educational institutions and programs could follow to establish a consistent and accurate evaluation method for a capstone course. Hospitality industry professionals and hospitality management faculty were interviewed through focus-group discussions, and a post-focus-group survey was conducted to determine a weighted percentage for each of the nine determined content domains. A test blueprint for a hospitality management capstone course was developed to measure programmatic student learning outcomes based on the weighted domains determined through this study. The results provide a usable instrument for hospitality and tourism management programs to enhance their current assessment methodology.  相似文献

This research examined how operational outcomes, relational outcomes and business performance are affected by a collaboration project between buyers and suppliers in a supply chain. It is hypothesized that interdependence of knowledge and process, supply chain partner insight, and the level of collaboration between the firms affect the outcomes of a collaboration project. Survey data from buyers and suppliers from a wide range of industries and organizations were used in this analysis. Among these participants, higher levels of collaboration led to improvements in operational and relational outcomes, which together led to improvements in asset utilization, competitive position, organizational performance, and profitability.  相似文献

Amidst the IASB's post-implementation review of IFRS 8, we examine how the standard's adoption changed the reporting of segments by European blue chips (i.e. companies comprising the top tier index of 14 European stock exchanges). We focus on anticipated benefits articulated in the IASB's Basis for Conclusions and concerns expressed by IFRS 8 opponents.In addition to convergence with U.S. GAAP, IFRS 8 results in the reporting of significantly more operating segments on average. However, most companies report the same number or fewer segments. Refuting claims regarding the loss of geographic data at the entity-wide level, we identify an improvement in the fineness of disclosures and a significant increase in the disclosure of geographic groupings. We do not identify an improvement in consistency of segment disclosures with other sections of the annual report, which is due to the consistency already achieved under IAS 14R.IFRS 8 results in a significant decline in the number of reportable segment information items (notably liabilities) and a significant decline in the reporting of capital expenditures at the entity-wide level. Furthermore, adoption of the standard produces a lack of comparability in segment profitability measures and extensive reporting of non-IFRS measures. However, almost all companies report a measure of segment profitability tied to a number on the consolidated income statement or reconciled to the income statement.  相似文献

The study of welfare participation in the United States prior to the 1996 Welfare Reform Act and afterward has primarily focused on comparing native and immigrant households. Analyses that have gone beyond this broad classification have focused on comparisons across race, with particular focus on Hispanic immigrants. This paper moves away from the existing literature by investigating whether there is a difference in welfare usage among immigrant based on their birthplace. Using a probit model, we investigate this potential difference by testing two related hypotheses. Our results suggest that the probability of welfare usage for immigrants with similar characteristic, differ for some immigrant groups. We also find that for some immigrant groups, citizen and noncitizens differ with respect to welfare usage.  相似文献
