Tourism, a global industry, brings with it a number of public health problems, one of which is the spread of sexually transmitted infections transmitted between travellers and hosts. Previous studies have largely focused on sex workers and sex tourists. This study assesses sexual behaviour, knowledge and condom use among male trekking guides in Nepal. A self-administered questionnaire survey (n...

background many countries conduct health impact assessment (hia) of their projects and policies to predict their positive and negative health impacts. in recent years many guides have been developed to inform hia practice, largely reflecting local developments in hia. these guides have often been designed for specific contexts and specific need, making the choice between guides difficult. the o...

Responding to natural language requires performing two major tasks: information processing (cognition), and decision making (conation). In order to motivate and best guide an entity performing such complex tasks, motivation must originate in the self-interest of the entity. This motivation guides cognitive and conative processes at the lowest possible level by assigning values (measures of impo...

We study two-component spatial optical solitons carrying an angular momentum and propagating in a self-focusing saturable nonlinear medium. When one of the components is small, such vector solitons can be viewed as a self-trapped vortex beam that guides either the fundamental or first-order guided mode, and they are classified as single- and double-vortex vector solitons. For such composite vor...

one of the factors which limits the transmission capacity of the fiber optics communication channel is the material dispersion. exact analytical study of the material dispersion is often complex and involves calculating the derivatives of the refractive index of the core. these calculations are too cumbersome to do, especially for high-order derivatives. so material dispersion has only been stu...

Objective The paper provides a review of current practices related to evaluation support services reported by seven biomedical and research libraries. Methods A group of seven libraries from the United States and Canada described their experiences with establishing evaluation support services at their libraries. A questionnaire was distributed among the libraries to elicit information as to p...

Self-differentiation refers to the differentiation of past “I” and present “I”, which exists in all self-narratives. In “Araby”, third story Dubliners, adult narrator tells his adolescent love for neighbour’s sister. The either language or “I”. Therefore, alternate, causing difference consciousness narrator. With both unity division, tension two narrative voices is caused, on one hand enriches ...
