Instant‐count sampling was tested on four municipal recreation areas in Athens, Georgia. Users were counted instantaneously on the areas at randomly selected times. From these counts, estimates of use and standard errors were achieved with a minimum of sampling time required. Errors ranged from 10.2 to 37.8 percent of estimated use and did not exceed 23.6 percent for total use.  相似文献

Approximately 40 quality assurance labels are in operation throughout the UK, namely for meat, salmon, milk, cereals, eggs, fruit and vegetables. Fresh meat quality labels are the most prevalent, thus requiring consumers to recognize and learn not only about the many nationally organized quality labels, but also the in-house retail labels. This paper identifies the meat purchasing behaviour of consumers and their perceptions, attitudes and knowledge towards the main quality assurance labels. Results indicate consumers' purchase preferences to be more influenced by quality labels co-ordinated by producer-led organizations, and that recognition and knowledge of retail labels are low in comparison. This raises questions regarding the relevance and communication strategies of in-house retail ‘quality assurances’ to consumers.  相似文献

This study investigated the meanings attached to leisure by low-income young consumers. In order to achieve this research objective, the study was conducted in a low-income community in the city of Rio de Janeiro. We used semi-structured interviews with community leaders and observation to acquire a preliminary knowledge of the field. We then interviewed 80 young people with ages varying from 15 to 25?years old. The data were treated qualitatively and quantitatively, using cluster analysis. The results showed, as expected, that these consumers have limited resources for leisure activities, due to lack of money, time or both. However, although the subjects recognise leisure as an important part of their lives, they attribute different meanings to it. Also, their understanding of free time and leisure varies somewhat. The findings provide evidence that these consumers' view of leisure, to some extent, resembles a pre-industrial understanding of leisure, associated with time for rest and time with family and friends. The results also permitted the identification of four different clusters, based on the meanings attributed to leisure and free time, individual aspirations and demographic characteristics.  相似文献

流行音乐作为当代艺术的一个重要门类,其传播方式和手段与传统社会大相径庭。现代商业社会的艺术传播,其效果不只是单纯由艺术水平来决定,而是由传播手段、传播方式与传播技巧等各种因素共同作用的结果。周杰伦歌曲创作的流行不失为现代艺术传播的经典案例。他的成功,除了他的音乐天赋之外,还在于他的创新意识,并善于体味和捕捉同时代年轻人的情感特点和欣赏习惯,将其融入自己的创作之中。同时其经纪人杨峻荣出色的商业运作,也是他获得巨大成功不可或缺的因素。  相似文献

Using a case study of a large public sector department the relationship between communication and change in a public sector department and the human resource implications of that relationship are considered. Senior administrators of the department signified their intention to change the culture from one that was considered to be bureaucratic, technically oriented and inward-looking to one more outward-looking, continually learning, more relationship-oriented internally and inclusive of broader ‘whole of government’ objectives such as commercialization, the environment, social justice and community relations. Findings from the research indicate that, despite an objective of shifting to a state of continual change with the mode of communication becoming two-way and dialogic, the communication mechanism has faltered due to a failure to address the need of lower-level staff for a set vision and stated future direction. Implications of these findings are drawn for public sector organizations in general.  相似文献
