Pro-tourism and anti-tourism community groups at a world heritage site in Turkey

This empirical study deepens our understating of support for sustainable tourism development (SSTD) from the perspectives of various community groups in Pamukkale, a world natural and cultural heritage inscribed on the UNESCO list. A quota sampling technique was used to survey the views of three communities: business, farmers, and the government. Occurrences of contrarian cases were checking using cross-tabulation analyses. Complexity theory and fuzzy-set qualitative comparative analysis (fsQCA), as an innovative approach, were applied to develop and test a configurational model for predicting both high and low SSTD scores for three community groups. The fsQCA results revealed that causal recipes for achieving pro-tourism behaviour are not simply mirror opposites of the conditions leading to anti-tourism behaviour. The complex configurational models indicating high/low SSTD were unique to each community group, indicating that a specified strategy must be developed for community-based tourism management. The evidence-of-fit validity of the measurement model and the predictive validity of the configurational model were provided. Support for the fsQCA results in the key tenets of complexity theory confirms that this theory explained the heterogeneity and complex interactions of SSTD antecedents well. The study outcomes provide a guideline for managing conditions to both increase SSTD and hinder SSTD negation for various community groups. The limitations and implications for further research are discussed.     

Pattern extraction for high-risk accidents in the construction industry: a data-mining approach

Accidents involving falls and falling objects (group I) are highly frequent accidents in the construction industry. While being hit by a vehicle, electric shock, collapse in the excavation and fire or explosion accidents (group II) are much less frequent, they make up a considerable proportion of severe accidents. In this study, multiple-correspondence analysis, decision tree, ensembles of decision tree and association rules methods are employed to analyse a database of construction accidents throughout Iran between 2007 and 2011. The findings indicate that in group I, there is a significant correspondence among these variables: time of accident, place of accident, body part affected, final consequence of accident and lost workdays. Moreover, the frequency of accidents in the night shift is less than others, and the frequency of injury to the head, back, spine and limbs are more. In group II, the variables time of accident and body part affected are mostly related and the frequency of accidents among married and older workers is more than single and young workers. There was a higher frequency in the evening, night shifts and weekends. The results of this study are totally in line with the previous research.     

The Politics of Resistance: Informal banks in the Caribbean

Informal banks are as relevant as they were in slave times because they are creating financial alternatives for marginalized people. I explore this issue with an empirical study of 398 business people in the slums of Jamaica and Guyana. I use intersectionality theorizing to explain that poor women organize local banks as a form of contestation against the threat of violence, partisan and informal politics. Women from poor communities mobilize economic resources through mutual aid to resist dependence on corrupt political systems and exclusionary financial institutions. I argue that the banker ladies reorganize money markets for themselves and others. By organizing inclusive financial programs the banker ladies also build social capital through managing locally-based economic resources.     

Nonpoint Source Pollution Control under Incomplete and Costly Information

We analyze the efficient management of nonpoint source pollution (NPS) under a limited pollution control budget and incomplete information. We focus on the tradeoff between data collection and pollution abatement efforts by incorporating information acquisition into a NPS pollution control model. Comparative static results show conditions under which (i) a favorable change in the abatement costs at one source may lead to an increase in the treatment level at all sources, and vice versa, (ii) an increase in data collection cost leads to an increase in data collection level, and (iii) an increase in the efficiency of information acquisition leads to a decrease in the level of data collection. More importantly, the model simulations illustrate that acquiring and exploiting information on heterogeneity of sediment loading distributions across polluting sources leads to a more efficient budget allocation and hence a greater reduction in pollution damage than would be the case without such information.     

Existence of a Universal Comparative Statics Matrix for Differentiable Optimization Problems

A universal existence theorem is established that yields exhaustive and constraint-free comparative statics information for a general, differentiable optimization problem in the preferred form of a semidefinite matrix. It subsumes all comparative statics formulations of differentiable optimization problems. Its relationship to comparative statics methods extant is establishedWe are grateful to an anonymous referee for a particularly helpful comment on the contents of this paper.     

Jump Spillover in International Equity Markets

In this article we study jump spillover effects between a numberof country equity indexes. In order to identify the latent historicaljumps of each index, we use a Bayesian approach to estimatea jump-diffusion model on each index. We look at the simultaneousjump intensities of pairs of countries and the probabilitiesthat jumps in large countries cause jumps or unusually largereturns in other countries. In all cases, we find significantevidence of jump spillover. In addition, we find that jump spilloverseems to be particularly large between countries that belongto the same regions and have similar industry structures, whereas,interestingly, the sample correlations between the countrieshave difficulties in capturing the jump spillover effects.
