The allocation of public places plays an extremely important role in the daily lives of inhabitants especially for recreational use that could enhance the quality of life of residents in the vicinity. To understand park users’ behavior is one of the most important prerequisites for as-sessing the participation in public service from the park users’ point of view. The pattern of park utilization on location and activity selection are important elements in behavioral study, while the public parks topograph may also influence the typical user’s be-havior. Questionnaire survey on park utilization was used to investigate the interaction between activity involvement and recrea-tional location with the use of linear discriminant analysis (LDA) model. The study found that public park users’ behavior is influenced not only by social characteristics but also by the recreational activities and their specific location characteristics. We found that about 45 percent of park visitors are local residents living within a radius of 3 km preferred travel to parks near their residential area. This implies that location selection behavior is correlated with travel distance, travel time and travel cost. Visit frequencies and on site expenditures reflect the recreation behavior for different type of activities. The overall information can be usefully applied by decision makers to launch appropriate public policy in consistence with the useful results of this study.展开更多

Focusing on the afterlives of photographic portraits produced during this “Occupy Gezi Movement”, the paper considers iconized digital portraitures as a peculiar genre of vernacular photography and focuses on its visual language, and cultural codes as a part of the underground resisting culture in daily life. It explores different contexts in which photographic portraits have been used as a tool of protest and their various kinds of remediation from the Gezi Park Protest onwards. Private portraits as an agent of resistance have been creatively modified, recreated, rematerialized and circulated in distinct ways during and after the protest: from city walls as stencils, stickers, and graffiti (in actual public spaces) to Facebook profile walls as online digital re-mastering (virtual spheres). This article concentrates on aesthetics of such iconized digital photographic portraitures in contemporary Turkey. It particularly focuses on one of the instances that have labeled the Occupy Gezi Movement: the death of Berkin Elvan, who turned 15 while in a coma who has been struck in the head by a tear gas canister, fired by police, while on his way to buy bread. This case has been a catalyst for further demonstrations against Turkey's ruling party and turned Elvan's high-spirited face and dark eyebrows, to one of the strong symbols of the resistance. The teenage boy's injury during the protests, his birthday while he was in a coma at the hospital, his death, funeral and commemorations have been stress points in which his photographic portrait have been modified and redesigned according to the occasion and circulated widely. The image of the youth symbol of the struggle and the different kinds of cultural work his photograph have performed is the main focus of this research. The digital social afterlives of Elvan's iconized imagery as illustrations and drawings; as stencils and graffiti at streets; as posters and framed photographs in political performances carried around in public spaces and commemorative acts; and as digital data circulated in social media both consisting of indexical and iconic dements regarding their photographic features. This transformation of the single analog vernacular photograph of Elvan to various digital versions and continuous re-interpretation and re-materialization is discussed depending on the local history of the occasion and the critical literature on photographic history and theories of photographic vernacularity. This research makes use of data collecting methods that netnographic research methodology uses. The paper focuses on the ways local vernacularity is historically produced and evolved in this particular time of Gezi Park Resistance.展开更多

In the montane forests of the Kahuzi-Biega National Park (KBNP) (East of DR Congo), it has been expanding very strongly for a decade, and is currently considered as having negative impacts on biodiversity conservation. In this paper, we test if S. scandens differs from three co-occurring, native, non spreading lianas (Gouania longispicata, Tacazzea apiculata and Adenia bequaertii) for functional traits which might influence plant expansion. For leaf traits (SLA, dry matter content, nitrogen concentration), S. scandens did not show extreme values compared to those of the three other lianas. In contrast, S. scandens had much higher biomass allocation to sexual reproduction. It also differs from the three other lianas for its reproductive strategy that combines both vegetative propagation and sexual reproduct/on, and propagule dispersal by wind. Moreover, S. scandens has larger leaves and a greater number of lateral branches per unit stem length. It is argued that the particular combination of functional traits exhibited by S.scandens may in part explain its propensity to behave as an opportunistic weed in the disturbed areas in the montane forests of Kahuzi-Biega.展开更多

The greening construction of the city can not meet the needs of the residents for the good environment. Recently, many large and medium-sized cities across the country have stepped up investment in country park, Its construction provides a good place to alleviate the pressure of life, Short-distance leisure for the city's residents. So it is worth exploring for Gucun Park that how to attract tourists in the fierce competition. The purpose of this paper is to stand in the height of the risk management system, putting forward the corresponding standardized risk response measures, which has great significance to the sustainable operation and development in the future.展开更多
