Postvisit Destination Loyalty Judgments: Developing and Testing a Comprehensive Congruity Model

Previous research has established the effect of self-congruity on both pre- and postvisit constructs, but its predictive power has appeared minimal. Departing from both classical and contemporary approaches to human needs and values, this study proposes a comprehensive model explaining more variance in postvisit destination loyalty judgments. The model comprises six explanatory variables, in addition to self-congruity: functional, hedonic, leisure, economic, safety, and m oral congruity. Based on a large-scale web survey among tourists (N = 973), the results provide good support for the proposed model (64% explained variance). Each of the seven congruity components exerts a significant influence on postvisit loyalty, but their relative contributions differ considerably. Other than self-congruity, functional, hedonic, leisure, and safety congruity exert the greatest influence on postvisit loyalty judgments; in contrast, economic and moral congruity have lesser influences. The authors discuss the results in light of their theoretical and practical implications for destination marketing. (author's abstract

Balanced Islands in Two Colored Point Sets in the Plane

Let $S$ be a set of $n$ points in general position in the plane, $r$ of which are red and $b$ of which are blue. In this paper we prove that there exist: for every $\alpha \in \left [ 0,\frac{1}{2} \right ]$, a convex set containing exactly $\lceil \alpha r\rceil$ red points and exactly $\lceil \alpha b \rceil$ blue points of $S$; a convex set containing exactly $\left \lceil \frac{r+1}{2}\right \rceil$ red points and exactly $\left \lceil \frac{b+1}{2}\right \rceil$ blue points of $S$. Furthermore, we present polynomial time algorithms to find these convex sets. In the first case we provide an $O(n^4)$ time algorithm and an $O(n^2\log n)$ time algorithm in the second case. Finally, if $\lceil \alpha r\rceil+\lceil \alpha b\rceil$ is small, that is, not much larger than $\frac{1}{3}n$, we improve the running time to $O(n \log n)$

Flip Graphs of Degree-Bounded (Pseudo-)Triangulations

We study flip graphs of triangulations whose maximum vertex degree is bounded by a constant $k$. In particular, we consider triangulations of sets of $n$ points in convex position in the plane and prove that their flip graph is connected if and only if $k > 6$; the diameter of the flip graph is $O(n^2)$. We also show that, for general point sets, flip graphs of pointed pseudo-triangulations can be disconnected for $k \leq 9$, and flip graphs of triangulations can be disconnected for any $k$. Additionally, we consider a relaxed version of the original problem. We allow the violation of the degree bound $k$ by a small constant. Any two triangulations with maximum degree at most $k$ of a convex point set are connected in the flip graph by a path of length $O(n \log n)$, where every intermediate triangulation has maximum degree at most $k+4$.Comment: 13 pages, 12 figures, acknowledgments update

Drivers of Human‒wildlife interactions in a co-existence area: a case study of the Ngorongoro conservation area, Tanzania

Communities in Africa bordering national parks or protected areas commonly overlap with wildlife. However, it is unclear to what degree such overlaps result in interactions with wildlife. The Ngorongoro Conservation Area (NCA) was designated a multiple land-use conservation area in 1959. Maasai and Datoga pastoralists and Hadzabe hunter-gatherers reside with protected wildlife in NCA. The study was carried out in four Maasai villages within the NCA, including Kayapus, Endulen, Meshili, and Nainokanoka. A cross-sectional study was used to assess drivers of human‒wildlife interactions using questionnaire surveys, focus group discussions, and field visits. A total of 396 households participated in the survey. The collected data were analysed using qualitative data analysis techniques and descriptive statistics such as frequencies and means. The habitat, which comprises water, pasture, shelter, and space, accounted for 100% of interactions, indicating that it is the primary driver of human‒wildlife conflict. Other driving factors for human‒wildlife interactions are the increase in wildlife, collections of firewood, domestic animals kept, and influence of community sleeping arrangements, searching for traditional medicines, and killing of lions for ritual purposes or defense. Large household sizes (36 family members) coupled with climate change have also driven and fuelled human‒wildlife interactions. Challenges identified as threatening human‒wildlife co-existence are injuries, deaths, disease transmission, and destruction of property. To mitigate human‒wildlife conflicts, the following are recommended: the increase in boarding schools coupled with the increase in enrolment of students in boarding schools or providing reliable transport, distribution of tap water, increasing food assistance to the community living in poverty, controlling population increase through reallocation the population in other areas, introducing zero-grazing, using biogas, discouraging community sleeping arrangements, i.e., humans with calves in the same house, improving record-keeping of the wildlife attacks, provisional dissemination of research findings to the community

Domesticating the ‘troubled family’: Racialised sexuality and the postcolonial governance of family life in the UK

This article examines how the UK’s Troubled Families Programme (TFP) works as a strategy of domestication which produces and delimits certain forms of ‘family life’. Drawing upon critical geographies of home and empire, the article explores how the TFP works to manage the troubled family as part of a longer history of regulating unruly households in the name of national health and civilisation. Viewing the TFP as part of the production of heteronormative order, highlights how the policy remobilises and reconfigures older forms of colonial rule which work to demarcate between civility/savagery, the developable/undevelopable. In examining the postcolonial dimension of neoliberal social policy, the article stresses how the TFP relies on racializing and sexualised logics of socio-biological control borrowed from imperial eugenics. Reading the TFP in this way contributes to our understanding of neoliberal rule. That the troubled family can be either domesticated or destroyed (through benefit sanctions and eviction) equally reveals the extent to which domesticity works as a key site for the production of both ‘worthy’ and ‘surplus’ life

Socioeconomic Assessment of Pigeonpea and Groundnut Production Conditions – Farmer Technology Choice, Market Linkages, Institutions and Poverty in Rural Malawi. Market Institution and Policy Research Report no.6

The Food and Agriculture Organization (FAO) of the United Nations (2008) reports that about 850 million people worldwide went hungry each year from the years 2002 to 2007. Furthermore, the United Nations (2008) reports, as the international financial crisis deepens, for the first time in history, one billion people were expected to go hungry in 2009. Agricultural growth is said to be the most effective means of addressing poverty. Consistent with this notion, the Department for International Development (2003) estimated that a 1% increase in agricultural productivity could reduce the percentage of poor people living on less than 1 dollar a day by between 0.6 and 2 percent. No other economic activity generates the same benefit for the poor. In Malawi, agriculture remains an important component of the economy; employing 85 percent of the labor force, accounting for about 39% of the Gross Domestic Product (GDP) and 83% of Malawi’s foreign exchange earnings (Chirwa 2007). The agricultural sector is subdivided into sub-sectors; estates and smallholder farmers. The latter accounts for 78% of the cultivated land and generates about 75% of Malawi’s total agricultural output, suggesting that Malawi’s agriculture is largely smallholder agriculture. More than 72% of the smallholder farms are less than one hectare, a size too small to achieve food self sufficiency at the household level with the current rudimentary farming methods. This notion is consistent with the Benin et al.(2008) report, that Malawi is the third most densely populated country in mainland sub-Saharan Africa (at 2.3 rural people per hectare of agricultural land) after Rwanda (3.8 people per hectare) and Burundi (2.7 people per hectare). Such small land holdings are a serious challenge to the transformation of Malawi’s agriculture. The principal crops grown in Malawi are maize, tea, sugarcane, groundnut, cotton..........
