Dipterocarpus dyeri is a typical plant of tropical evergreen moist forest at Southeast Vietnam. These plants have been planted popularly at parks and urban streets for the shade and it has been commonly materials for timber industry. Multiplication of Dipterocarpus dyeri at nurseries could face to some diseases, such as the withered disease cause serial death. Our study isolated three disease fungi strains from the root areas of the diseased Dipterocarpus dyeri planted Ma Da nursery, Dong Nai province. Result of 28s rDNA sequencing showed these fungi belong to Ophiostoma eucalypticagena, Aspergillus nidulans and Collectotrichum gloeosporioides. This result is base for conducting the following studies to control the withered disease on Dipterocarpus dyeri at the nursery.

The increasing popularity of street redesigns highlights the intense competition for street space between their different users. More and more cities around the world mention in their planning documents their intention to rebalance streets in favor of active transportation, transit, and green infrastructure. However, few efforts have managed to formalize quantifiable measurements of the balance between the different users and usages of the street. This paper proposes a method to assess the balance between the three fundamental dimensions of the street—the link, the place, and the environment—as well as a method to assess the adequation between supply and demand for the link dimension at the corridor level. A series of open and government georeferenced datasets were integrated to determine the detailed allocation of street space for 11 boroughs of the city of Montréal, Canada. Travel survey data from the 2013 Origine-Destination survey was used to model different demand profiles on these streets. The three dimensions of the street were found to be most unbalanced in the central boroughs of the city, which are also the most dense and touristic neighborhoods. A discrepancy between supply and demand for transit users and cyclists was also observed across the study area. This highlights the potential of using a distributive justice framework to approach the question of the fair distribution of street space in an urban context.

Incident Duration

The effect of incidents on capacity is the most critical parameter in estimating the influence of incidents on network performance. The Highway Capacity Manual 2010 (HCM 2010) provides estimates of the drop in capacity resulting from incidents as a function of the number of blocked lanes and the total number of lanes in the freeway section. However, there is limited information on the effects of incidents on the capacity of urban streets. This study investigated the effects on capacity of the interaction between the drop in capacity below demand at a midblock urban street segment location and upstream and downstream of signalized intersection operations. A model was developed to estimate the drop in capacity at the incident location as a function of the number of blocked lanes, the distance from the downstream intersection, and the green time–to–cycle length (g:C) ratio of the downstream signal. A second model was developed to estimate the reduction in the upstream intersection capacity resulting from the drop in capacity at the midblock incident location as estimated by the first model. The second model estimated the drop in capacity of the upstream links feeding the incident locations as a function of incident duration time, the volume-to-capacity (V/C) ratio at the incident location, and distance from an upstream signalized intersection. The models were developed on the basis of data generated with the use of a microscopic simulation model calibrated by comparison with parameters suggested in HCM 2010 for incident and no-incident conditions and by comparison with field measurements.

The Relationship

The relationship between masculinity, crime, and violence has a long history, whereby hegemonic masculinity is utilized as a resource to create and sustain tough reputations “on road”, where everyday lives are played out on urban streets. Within the context of road culture—of which gangs are part—this is particularly significant given the hypermasculine focus. This paper considers Raewyn Connell’s (1995; 1997; 2000) work on hegemonic masculinity and emphasized femininity and develops it in new directions by exploring how these hegemonic identities are inscribed on women’s bodies. In the English context, the dominant discourse around young women “on road” is of that of passivity, as they are victims first and offenders second. An underexplored area is their role as perceived “honorary men” when adopting behavior associated with hegemonic masculinity, therefore how they bargain with patriarchy within these spaces is explored.

Square dancing is a popular music-related group physical exercise for health benefits in China mainly participated by mid-aged women and elderly people. This paper investigates the soundscape and enjoyment of the square dancing in urban streets through a case study in Lichuan, a county level city in southwest China, in December 2017. It examines the impact of gender, age, participation and places on perceptions of square dancing soundscape. Two sites along two main urban streets in the city were selected to conduct onsite investigations where residents spontaneously perform square dancing on a daily basis. Ethnographical observations were conducted to identify the social-physical features and sounds of both sites during the dance and without dance. Sound pressure measurements (LAeq and LAmax) were also conducted under the two conditions. An off-site survey was distributed through the local social media groups to understand residents’ everyday experiences and perceptions of square dancing in the city; 106 responses were received for the off-site survey. T-tests and Chi-squared tests were used for statistical analysis of the survey data. The results show gender does appear to be a factor influencing the regularity of participation in square dancing, with a bias towards more female participants. Participation frequency of square dance has an impact on the enjoyment of square dancing. There is no correlation between the dislike of watching square dancing, or dislike of the music and a desire to restrict locations for square dancing.
