Asymptotic behavior of Laplacian eigenvalues of subspace inclusion graphs

Let $\text{Fl}_{n,q}$ be the simplicial complex whose vertices are the non-trivial subspaces of $\mathbb{F}_q^n$ and whose simplices correspond to families of subspaces forming a flag. Let $\Delta^{+}_k(\text{Fl}_{n,q})$ be the $k$-dimensional weighted upper Laplacian on $\text{Fl}_{n,q}$. The spectrum of $\Delta^{+}_k(\text{Fl}_{n,q})$ was first studied by Garland, who obtained a lower bound on its non-zero eigenvalues. Here, we focus on the $k=0$ case. We determine the asymptotic behavior of the eigenvalues of $\Delta_{0}^{+}(\text{Fl}_{n,q})$ as $q$ tends to infinity. In particular, we show that for large enough $q$, $\Delta_{0}^{+}(\text{Fl}_{n,q})$ has exactly $\left\lfloor n^2/4\right\rfloor+2$ distinct eigenvalues, and that every eigenvalue $\lambda\neq 0,n-1$ of $\Delta_{0}^{+}(\text{Fl}_{n,q})$ tends to $n-2$ as $q$ goes to infinity. This solves the $0$-dimensional case of a conjecture of Papikian

News from the motherland: a content analysis of existential tourism magazines in Southern China

Ethnic Chinese who reside outside of mainland China proper constitute an enormous opportunity for tourism and economic development in China (Lew & Wong, 2003). Overseas Chinese have a strong sense of common origin, based on both racial and cultural grounds, which are further enhanced by business, social, and familial ties. These ties often take the form of existential tourism, which Cohen (1979) defined as travel back to a personal or spiritual “center” located away from one's home. This article presents the results of a content analysis of publications from Guangdong Province in China for ethnic Chinese residing outside of China. The content analysis results indicated that very strong existential tourism ties exist between Guangdong Province and the US and Canada in North America, and to adjacent Hong Kong and Macau. Examples of efforts to strengthen common origins included 56 articles on biographies of overseas Chinese individuals and 24 articles on overseas Chinese society and culture (out of 176 articles examined). Other major topics included efforts to build networks and investments, domestic news articles, donation story articles, education-related articles, investment-related articles, and articles on activities of local overseas Chinese Affairs Offices. Stories of rootfinding visits and the theme of “Love of -Country” were also prominent. These magazines indicated how local overseas Chinese Affairs Offices are proactive in strengthening ties with overseas Chinese through travel and tourism, upon which social and then business networks can be established

Perceptions of tourists and tour guides in Singapore

Significant differences exist between tourists and professional tour guides in their perceptions of place. A survey conducted in Singapore of English-speaking foreign tourists and their local tour guides found this to be the case. Tour guides highlighted the major hotels and attractions, while downplaying less prominent sites and events. Tourists also seek the major attractions, but at the same time want a broader and more complex experience. These differences can be attributed to the roles of tourists as guests and tour guides as culture brokers, and in the behavioral space associated with these roles. Survey results demonstrate the importance of understanding these roles in international and cross-cultural tourism

Long Tail tourism: New geographies for marketing niche tourism products

The Long Tail concept refers to the Internet-based economy that has enabled company success through a focus on highly specialized services and products that are not in high volume demand, but maybe in high-value demand. The concept of the post-tourist, for example, is a Long Tail phenomenon. Long Tail marketing approaches are proving success due to advances in technology and social networking that have given more people access to a broader range of goods and services and information. The Long Tail is not without its challenges, including increased global competition, and has not abandoned geographic considerations. Geography, in fact, can help to differentiate niche products and must still be overcome to consummate the tourist experience

Modeling tourist movements - A local destination analysis

Models depicting the spatial movement patterns of tourists within a destination are proposed in this paper. The models are developed using an inductive approach based on urban transportation modeling and tourist behavior, to identify explanatory factors that could influence movements. Factors identified included a set of destination characteristics and a set of tourist characteristics that influence decision making and behavior. These factors influence movement patterns in two ways, resulting in four types of territorial models and three linear path models. Understanding the movement of tourists within a destination has practical applications for destination management, product development and attraction marketing

Social media for academic programs & departments

Social media for organizations, such as an academic department or a degree program, consist of a range of web-based applications that allow anyone to disseminate information to online communities. The principle reasons for creating a social media presence for an academic department or program include: (1) Create an online social community for current students; (2) Create an extended community of alumni and friends; and (3) Create an awareness of the department or program among potential students
