Prevalence of intestinal parasites in dogs from public shelters in Serbia

Data on endoparasitic infections in dogs from dog shelters in Southeastern Europe are limited; thus, this study aimed to add to the existing knowledge on this topic by reporting on the prevalence of intestinal parasites in dogs from public dog shelters in the Republic of Serbia. In 2017 and 2018, individual and pooled fecal samples, were collected from 1267 dogs from six shelters. All samples were qualitatively examined for parasites using flotation tests. Seven taxa of intestinal parasites were identified: Cystoisospora spp., ascarids: Toxocara canis and Toxascaris leonina, hookworms, Trichuris vulpis, taeniids and Dipylidium caninum. The overall prevalence of intestinal parasites was 58. 3 % (78. 1 % in young dogs and 53.1 % in adult dogs). The parasites detected in both young (<1 year old) and adult dogs (>1 year old) were Cystoisospora spp. (20 % and 4.9 %), T. canis (33.5 % and 14.7 %), T. leonina (7.7 % and 2.3 %), and hookworms (16.9 % and 15 %), respectively. However, T. vulpis (9.6 %), taeniids (1.3 %), and D. caninum (5.4 %) were detected only in adult dogs. In the Belgrade shelter, young dogs had a higher prevalence of endoparasitic infections (18.9 %, 49/260) than adult dogs (14.8 %, 149/1007). In the Subotica, Jagodina and Niš shelters, young dogs had significantly higher (p < 0.001 and p < 0.05, respectively) prevalence of endoparasitic infections (10 %, 12.3 % and 14.6 %) than adult dogs (5.3 %, 8 % and 7.2 %). These results will be useful for establishing health care programs in dog shelters and implementing effective strategies for the control of intestinal parasites.     

Introduction to the International Symposium on Lipid Science and Health and research progress in lipid science and health

The International Symposium on Lipid Science and Health (ISLSH), which was organized annually by Oil Crops Research Institute of Chinese Academy of Agricultural Sciences (OCRI-CAAS) since 2016, has gained a strong reputation and attracted hundreds of delegates from around the world for discussion of lipid research trends and advances every year, to promote research and academic exchanges in the fields of lipid science and health. The 5th International Symposium on lipid Science and Health was successfully held in Wuhan, China, from October 23rd to 25th, 2020, to celebrate the 60th anniversary of OCRI-CAAS. The two-day symposium gathered well-known experts specialized in lipid science to share the current state of lipid research with emphasis on aspects covering: (1) lipid profiling and characterization, (2) lipid preparation and modification, (3) lipid improvement and regulation, and (4) lipid nutrition and health. The symposium was conducted by a combination of on-site and network meeting. More than 250 distinguished delegates from academia and industry participated in the on-site multidisciplinary meeting, and thousands of scholars attended the virtual event. This paper is as a record of the symposium proceedings and a brief summary of the advances and trends in 4 aspects of lipid science and health.     

Societal expectations of livestock farming in relation to environmental effects in Europe

The potential environmental effects of livestock farming are mainly associated with intensification of poultry, pig and dairy cow production systems. The major impacts are mainly caused by housing of livestock, which can lead to air and water pollution associated with nitrogen and phosphorus emissions and losses from manure. European countries regulate the potential for these types of pollution through a number of mechanisms, which have received wide public acceptance. In grazing systems, nitrogen pollution, associated with the use of nitrogen fertilizer, is also the subject of legislation. Perhaps because of this regulatory approach, surveys of the public have found that human food quality and animal welfare are more important issues than effects on air and water quality when considering livestock systems.Variation in stocking rates of grazing ruminants can change the structure and composition of pastures with potential impacts on biodiversity and the production of methane, a greenhouse gas. In European countries, maximum stocking rates have been set to reduce these impacts. Surveys of the European public have suggested that they are willing to pay for the mitigation of these environmental effects but that they also value strongly the cultural component of grazed livestock systems. There are few underlying concepts about how society views the environmental impacts of livestock systems. These are used to conclude that current attitudes are likely to prevail in the next decade.

与谢芜村的俳句、绘画艺术与中国文化

从规模与结构两方面，实证分析了我国社会性基本公共服务财政支出对居民消费的影响，同时对城乡差异性在社会性基本公共服务供给方面的表现进行了分析。实证发现：2007~2012年间，我国社会性基本公共服务财政支出对居民消费的影响不显著，并具有明显的城乡差异性。从分项来看，教育支出对居民消费的影响效果不显著，在城乡差异表现方面，教育支出对城镇居民消费的影响效果不显著，但对农村居民消费却有着一定的挤入效应；社会保障和就业支出对居民消费具有一定的挤出效应，但在城乡差异表现方面，这种影响都不显著；医疗卫生支出对居民消费具有一定的挤入效应，且挤入作用在城乡之间的差异较小。     

论青少年体质健康的耗散结构*

目的：从耗散结构理论的角度研究解决我国青少年体质健康普通下降的严重问题，对解决我国青少年体质健康问题不仅具有独特的理论价值，而且具有显著的实践意义。方法：理论思辨法和逻辑分析法。结论：1.青少年体质健康普通下降的重要原因是其系统的耗散结构无法形成；2.解决青少年体质健康问题的重要途径在于促进其系统的耗散结构形成；3.开放性,远离平衡与非线性是青少年体质健康系统形成耗散结构的前提；4.满足青少年自我实现的愿望和体育锻炼的需求是青少年体质健康系统能够形成耗散结构的关键。     

Citizens’ perception of and satisfaction with urban forests and green space: Results from selected Southeast European cities

In this paper the results of the first comprehensive study on perception of and satisfaction with urban forests and green space in seven Southeast European cities are presented. The aims of the paper are to analyse 1) citizen perceptions of the current state of urban forests and green space in their cities, 2) to what extent current urban forests and green space meet their needs and how this can be improved. A cross-sectional study was conducted by using a common face-to-face survey questionnaire. Respondents were selected based on census data though a stratified sampling procedure by taking into account age, gender and city district (n = 384 in each city). The results showed that citizens genuinely care for urban forests and green space in their cities, but are not satisfied with their current state. The respondents found issues related to misbehaviour of other users, the presence and quality of facilities, as well as the presence and quality of management or maintenance the most pressing. There were more statistically significant differences than similarities between cities. Socioeconomic variables explained perceptions only to some extent. Citizens were very supportive of educational campaigns about the importance of urban forests and green space as well as of better enforcement of the existing regulations though having more community wardens that were expected to tackle current unsatisfactory situations. Urban planning and urban forest and green space management in these cities are facing many problems characteristic for post-socialist countries. Study findings are expected to contribute to decision making in urban planning and natural resource management.
