Pro-environmental behaviours of visitors to Thailand’s national parks and factors discriminating the behaviours

ABSTRACT

The objectives of this study were to classify types of pro-environmental behaviours (PEBs) and to investigate factors discriminating PEBs of visitors to national parks in Thailand. The questionnaire was used to collect data from 800 Thai visitors. Data was analysed using factor analysis and discriminant analysis. The findings demonstrated that PEBs were classified into three groups. Perceived controllability represented the key variable discriminating the PEBs of visitors. The recommendations for provoking PEBs are 1) improving basic facilities to encourage PEBs of visitors, and 2) creating effective interpretive messages, which address the beneficial consequences when action is taken with appropriate behaviour.     

Identifying the factors behind fatal and non-fatal road crashes: a case study of Lahore,Pakistan

ABSTRACT

The study identifies the factors behind fatal and non-fatal road crashes in Lahore, Pakistan, by investigating 461 reported cases to Traffic Police Lahore that occurred during January–November 2014. Road crashes are categorized into fatal and non-fatal crashes and, because of the binary nature of the dependent variable, logistic regression is used to identify the factors behind these crashes. As a follow-up, discriminant analysis is employed to classify the factors related to fatal and non-fatal crashes. The logistic regression results reveal that females are at higher risk of fatalities than male drivers. Among vehicle types, rickshaws and cars are more involved in fatal accidents because both are growing at large on roads. Long trucks and trailers are also involved in fatal accidents, mainly because of their huge size and drivers’ risky driving behaviours. It is also noted that risk of fatalities is higher in case where two vehicles bumped each other. Speeding and overloading are the common behaviours resulting in fatal crashes. Better urban transport systems and strict compliance with traffic rules and regulations may improve road safety in Pakistan.

A Typology of Partial-Order: The Case of Drug Use in Israel

A frequent variety of typology is that which results when a given population is classified simultaneously by several criteria, the categories of each criterion being ordered in a sense common to all the criteria. Such simultaneous orderings automatically define a partial order typology.The empirical problem is to ascertain the dimensionality and the substantive meaning of the partial order. This is illustrated here by characterization of the Jewish population of Israel by the frequencies of use of a variety of drugs. The data analysis approach adopted is that of Partial Order Structuple (Scalogram) Analysis (POSA). The particular computer program used is POSAC (POSA with Base Coordinates).The analysis revealed that it is possible to portray the distinct profiles (structuples) of the respondents according to drug use in a two-dimensional space, with a substantive regularity relating both to legal (pain relievers) and illegal drugs (marijuana, methadon). This space also serves as a basis for discriminant analysis for age as an external background variable.
