The impact of ecotourism on the environment in Nyanga is also examined. The paper employs both literature review(secondary data) and a field survey(primary data) to achieve these objectives. To gather socioeconomic data of households and tourist traits, questionnaires were administered to120 households and 30 tourists in the study area. Key informant interviews were held in the survey to gather expert knowledge about ecotourism trends and environmental data in the area.Data were analyzed using Statistical Package for Social Sciences. Descriptive and inferential analyses were used for quantitative data while content and structural-functional analyses were used for qualitative data. The research revealed that ecotourism offers the highest salaries when compared to other sources of formal employment. Ecotourism activities were shown to positively impact the environment through the protection, preservation, and management of natural resources. The study concludes that ecotourism is a useful and sustainable poverty alleviation strategy which has not yet been fully exploited in Zimbabwe.展开更多

Contemporary CGSNs, such as Dianping and Trip Advisor, are often the targets of click farming in which fake reviews are posted in order to boost or diminish the ratings of listed products and services simply through clicking. Click farming often emanates from a collection of multiple fake or compromised accounts, which we call click farmers. In this paper, we conduct a three-phase methodology to detect click farming. We begin by clustering communities based on newly-defined collusion networks. We then apply the Louvain community detection method to detecting communities. We finally perform a binary classification on detected-communities. Our results of over a year-long study show that(1) the prevalence of click farming is different across CGSNs;(2) most click farmers are lowly-rated;(3) click-farming communities have relatively tight relations between users;(4) more highly-ranked stores have a greater portion of fake reviews.展开更多

Al-Wardi was the main person who established the first department of sociology in Iraq and the spiritual father or the real father of sociology in the country. He wrote prestigious works about the Iraqi society including some hypotheses focusing on the Iraqi personality, such as the dual personality and social dissonance. These findings and hypotheses are not above criticism of course. The method we depend on here is the content analysis methodology. The paper consists of seven parts; part one is the introduction which includes a short glimpse on the subject and A1-Wardi's methodology. Part two deals with Al-Wardi and studying Iraqi personality. Part three, discusses the dual personality, and part four, the social dissonance. Part five, exposures tackling the problem where Al-Wardi suggests some points. Part six deals with the discussion. Finally, there is a conclusion under the part seven.展开更多

In this direction, the International Accounting Standards Board (IASB) has highlighted some content elements recognised as being fundamental for guaranteeing the usefulness of the management commentary. With reference to these elements, it is interesting to analyse the level of disclosure of the financial reporting. These analyses aim to identify the themes dealt with most extensively by the companies and those that require greater attention so that the narrative section of the financial statement is, on the one hand, at least consistent with the suggestions of the guideline and, on the other hand, contains information that is useful for the users. Lastly, in the light of the relevant European Union (EU) directives, the results of the analysis will help to formulate considerations on the ability of the IASB guideline to improve the completeness of the narrative section. All this is examined in a cross-country dimension: Financial reports in Italy and the United Kingdom (UK) are examined. The content analysis methodology is applied. Within the financial reporting, the management discussion is examined in particular. The analysis is performed considering 2008. This qualitative paper will contribute to the studies on disclosure and usefulness of the information provided.展开更多

The study is organized as follows. After reviewing the relevant literature on financial disclosure and MC, this paper examines the content of the Italian management's report-----known as "Relazione sulla Gestione" and that of the recent IASB's IFRS practice statement. Hence, it applies a self-constructed disclosure index and a multiple correspondence analysis (MCA) on MC of a sample of 66 Italian non-financial listed firms. The results show that the level of disclosures provided by the Italian listed firms does not seem to be affected by the IASB's guidelines. However, the survey highlights large differences in the level and type of disclosure provided in MC among the sectors and firms. This paper aims to contribute to the financial reporting debate by understanding the IASB's guidelines and their impacts on the voluntary disclosure practices of Italian listed firms.展开更多

However, in the field of the concession addresses, the studies on this kind of political text are limited. The winners of presidential election always draw much attention from the world and their speeches, for example, presidential inaugural address has been a hot study topic of linguistics. Nevertheless, the losers of presidential election are always neglected by the world and the study on concession address is scarce and rare. Therefore, the meaning of study on the concession speech helps fill the gap of the discourse analysis. This thesis applies the PDA under the framework of appraisal theory to analyze five concession speeches with a combination of qualitative and quantitative approaches. This study aims to complement CDA (Critical Discourse Analysis) to emphasize positive social construction of political discourse.展开更多

WS community as a mean to provide an ontological organization of WSs that share the same domain of interest has realized this kind of fancy in the sense that providers can work together to compete against others outside the community. Service selection in WS community is different from the traditional service selection, since WS community should take into account its own benefits. Therefore, we propose a hybrid approach to make service selection in WS community. The approach considers the profits of both WS community and the services within it. The experimental evaluation shows that the approach has a great advantage over other approach without consideration of community's benefits.展开更多

Proceeding from...Barrington Moore's "No bourgeoisie, no democracy" made democracy a monopoly of the bourgeoisie. Today, this has evolved into Huntington's thesis that the middle class has brought with it democracy. Proceeding from the relationship between the history of the socialist movement and comparative institutional change, we find that democracy has experienced a process of development involving the combination of positive and negative, from its original purpose of realizing majority rule in which everyone is equal to a tool for protecting the property rights of the minority, viz. the bourgeoisie, and thence to a tool for the mass of the people to realize equal rights today. In the course of its development, the main contribution of the bourgeoisie has been constitution-building and elite democracy, while the advent of mass democracy should be attributed to the workers' movement with the lower classes as its main force and to the struggles of other non-bourgeois strata. To gain a renewed awareness of the socialist attribute of democracy on the basis of an examination of the historical course of democracy helps us question the universality of a social science shaped by particular experiences.展开更多
