Understanding environmental influences on walking - Review and research agenda

Background: Understanding how environmental attributes can influence particular physical activity behaviors is a public health research priority. Walking is the most common physical activity behavior of adults; environmental innovations may be able to influence rates of participation. Method: Review of studies on relationships of objectively assessed and perceived environmental attributes with walking. Associations with environmental attributes were examined separately for exercise and recreational walking, walking to get to and from places, and total walking. Results: Eighteen Studies were identified. Aesthetic attributes, convenience of facilities for walking (sidewalks, trails); accessibility of destinations (stores, park, beach); and perceptions about traffic and busy roads were found to be associated with walking for particular purposes. Attributes associated with walking for exercise were different front those associated with walking to get to and from places. Conclusions: While few studies have examined specific environment-walking relationships, early evidence is promising. Key elements of the research agenda are developing reliable and valid measures of environmental attributes and walking behaviors, determining whether environment-behavior relationships are causal, and developing theoretical models that account for environmental influences and their interactions with other determinants.

Effects of tourism development on the local poor people - Case study in Taibai Region China

In China, protected areas are one of the main destinations attracting tourists and homeland for many poor people living in and around them. Based on a case study, the paper focuses on correlation between tourism and poverty alleviation by tracing the cash flows to the local poor. It also reviews the social and environmental effects of tourism on local area. The case study is conducted in a group of protected areas in Qinling Mountain Region in Shaanxi, a western province in China. Qinling Mountain is one of the most important distribution zones for Giant Panda and some other endangered wildlife such as Golden Takin and Golden Monkey. The tourism development in the region is happening. Research indicates that there is 29.33%, of tourist expenditure is going to local households, directly or indirectly. Tourist spends US$7.11 (13.67%) in food and beverage, and US$6.39 (12.23%) in accommodation service, which are the greatest contributors to local households in terms of tourism benefits. Local households can get US$8.15 from food/beverage and accommodation sectors, taking 56.64% of total income from tourism. Generally, tourism development benefits all stakeholders. However, poor people get less benefit. The paper analyses the barriers for the poor to be involved in tourism development, and discusses the government roles, major issues in implementation of Sustainable Tourism-Eliminating Poverty (ST-EP) model.

Tourists and beach safety in Queensland, Australia

Surf Life Saving Queensland (SLSQ) is a leading authority on beach safety, providing patrol, education, and rescue services to both tourists and local residents along the coast of Queensland, Australia. SLSQ recognizes that tourists are a target group requiring special attention due to their unfamiliarity with ocean beaches and surfing activities, and in some cases having the additional challenge of poor swimming skills, language barriers, and disorientation in a foreign vacation environment. This article describes SLSQ initiatives to provide beach safety for tourists through a focus on service delivery and partnerships with the tourism industry and relevant government agencies. The positive involvement of SLSQ in tourism is a model for other coastal destinations, given that drowning is the second most frequent cause of injury death among international travelers.

Arf6-independent GPI-anchored protein-enriched early endosomal compartments fuse with sorting endosomes via a Rab5/phosphatidylinositol-3 '-kinase-dependent machinery

In the process of internalization of molecules from the extracellular milieu, a cell uses multiple endocytic pathways, consequently generating different endocytic vesicles. These primary endocytic vesicles are targeted to specific destinations inside the cell. Here, we show that GPI-anchored proteins are internalized by an Arf6-independent mechanism into GPI-anchored protein-enriched early endosomal compartments (GEECs). Internalized GPI-anchored proteins and the fluid phase are first visualized in GEECs that are acidic, primary endocytic structures, negative for early endosomal markers, Rab4, Rab5, and early endosome antigen (EEA)1. They subsequently acquire Rab5 and EEA1 before homotypic fusion with other GEECs, and heterotypic fusion with endosomes containing cargo from the clathrin-dependent endocytic pathway. Although, the formation of GEECs is unaffected by inhibition of Rab5 GTPase and phosphatidylinositol-3'-kinase (PI3K) activity, their fusion with sorting endosomes is dependent on both activities. Overexpression of Rab5 reverts PI3K inhibition of fusion, providing evidence that Rab5 effectors play important roles in heterotypic fusion between the dynamin-independent GEECs and clathrin- and dynamin-dependent sorting endosomes.

Neighborhood environmental factors correlated with walking near home: Using SPACES

Purpose: The physical environment plays an important role in influencing participation in physical activity, although the specific factors that are correlated with different patterns of walking remain to be determined We examined correlations between physical environmental factors and self-reported walking for recreation and transport near home. Methods: The local neighborhood environments (defined as a 400-m radius from the respondent's home) of 1678 adults were assessed for their suitability for walking. The environmental data were collected during 2000 using the Systematic Pedestrian and Cycling Environmental Scan (SPACES) instrument together with information from other sources. We used logistic regression modeling to examine the relationship between the attributes of the physical environment and the self-reported walking behavior undertaken near home. Results: Functional features were correlated with both walking for recreation (odds ratio (OR) 1.62; 95% confidence interval (Cl): 1.20-2.19) and for transport (OR 1.30; 95% Cl: 0.97-1.73). A well-maintained walking surface was the main functional factor associated with walking for recreation (OR 2.04; 95% Cl: 1.43-2.91) and for transport (OR 2.13; 95% Cl: 1.53-2.96). Destination factors, such as shops and public transport, were significantly correlated with walking for transport (OR 1.80; 95% Cl: 1.33-2.44), but not recreation. Conclusion: The findings suggest that neighborhoods with pedestrian facilities that are attractive and comfortable and where there are local destinations (such as shops and public transport) are associated with walking near home.

Stormy Outlook? Domestic students' impressions of international students at an Australian University

The education of international students in Australian universities has grown significantly over recent years, with Australia now having the highest ratio of international students to domestic students among the major English-speaking destinations popular with international students. While there is a variety of research that examines the learning experiences of international students, little research has been conducted that examines the impact that international students have on their domestic counterparts. This paper reports on research that solicits the perceived advantages and disadvantages held by 301 domestic students, who are sharing their educational experience with international students studying hospitality and tourism management. The study reveals that there is a sizable proportion of domestic students (28%) who consider that there are too many international students on campus; that domestic and international students do not readily mix and it also highlights the fact that racist incidents occur. It is suggested that institutions wishing to increase their number of international students must take into consideration the feelings and concerns of their domestic students.

Sustainable tourism planning: A content analysis of local tourism plans

Tourism planning has been advocated by many as a possible means of alleviating some of the negative impacts of tourism. While a number of approaches have evolved, tourism planning based on the philosophies of sustainability has emerged as the most comprehensive approaches. To investigate the tourism planning approaches of local tourism destinations in Queensland, particularly the extent to which tourism plans exhibit the sustainable approach to tourism planning, 30 local tourism planning documents have been reviewed. Despite claims that sustainable tourism planning is one of the most accepted approaches the study has shown that this is not necessarily the case in practice. It was found that although a number of plans addressed the issue of sustainability, the subsequent strategies and actions suggest that the sustainable approach is not the dominant planning approach, but in fact the economic and infrastructure approaches are the primary planning methods.

Achieving key dimensions of sustainability: Strategic visioning as a tourism destination planning tool

Tourism has had, and is continuing to have, a profound impact upon destinations, economically, environmentally and socially. The negative impacts of tourism have been attributed, among other things, to inadequate or non-existent planning frameworks for tourism development, and it has therefore been advocated that tourism planning is vital to offset some of these negative impacts. While several different approaches have been supported over the years, tourism planning based on the philosophies of sustainability has emerged as one ofthe most comprehensive approaches. However, two critical concepts have been identified as precursors to sustainable development: a strategic Qrientation towards tourism planning and enhanced levels of multiple stakeholder participation in the tourism planning process (Simpson 2001 ). While both strategic tourism planning and stakeholder participation and collaboration, have received considerable attention in the academic literature, there has been relatively little written about its practical application. However, the somewhat recent emergence of the strategic visioning concept as a destination planning tool may provide the necessary practical framework for incorporating stakeholder collaboration into destination strategic planning and management. This paper will provide a synthesis of the stakeholder collaboration, strategic planning and strategic visioning literatures, before conceptually examining the potential applicability._ of the strategic visioning process in achieving meaningful stakeholder participation and collaboration in destination planning.

Multi-threaded Communicating Agents in Qu-Prolog

In this tutorial paper we summarise the key features of the multi-threaded Qu-Prolog language for implementing multi-threaded communicating agent applications. Internal threads of an agent communicate using the shared dynamic database used as a generalisation of Linda tuple store. Threads in different agents, perhaps on different hosts, communicate using either a thread-to-thread store and forward communication system, or by a publish and subscribe mechanism in which messages are routed to their destinations based on content test subscriptions. We illustrate the features using an auction house application. This is fully distributed with multiple auctioneers and bidders which participate in simultaneous auctions. The application makes essential use of the three forms of inter-thread communication of Qu-Prolog. The agent bidding behaviour is specified graphically as a finite state automaton and its implementation is essentially the execution of its state transition function. The paper assumes familiarity with Prolog and the basic concepts of multi-agent systems.
