The purpose of this study is to identify the association between risky sexual behaviors and migration intentions among adolescents living in Guanajuato, Mexico.

Data were collected by self‐administered questionnaires to students enrolled in an alternative schooling system in Guanajuato, Mexico, during the school year of 2006‐2007. The sample size for this study includes 538 unmarried students, 35 percent male, ages 14‐19. Ordinal logistic regression is used to estimate the odds of engaging in risky sexual behaviors.

The results reveal that male adolescents with higher intentions to migrate have significantly higher odds of engaging in risky sexual behaviors than both males who are less interested in migrating and females, regardless of their migration intentions.

Interventions on both sides of the US/Mexico border are needed in order to address this concern particularly among males who express a desire to migrate to the US someday.

These findings highlight the importance of examining risky sexual behaviors even before migration to the US occurs. By engaging in high risk sexual behaviors prior to migrating, adolescents are putting themselves and both their sexual partners in Mexico and their future sexual partners in the US at increased risk of contracting STIs and HIV.

The study examined risky sexual behavior of adolescents in Mexico prior to migration. Knowledge about risky sexual behaviors prior to departure is vital for policy makers and researchers as they seek to design and implement interventions aimed at quelling this growing public health concern.

Age at migration is commonly utilized as a proxy measure for assimilation in health behavior research. We reconsider this approach by examining the role of continued connection with places of origin on alcohol use, an important marker of health behavior and overall population health. Cross-border connections may buffer the association between earlier age at migration and alcohol use by providing an alternative channel of influence for behavioral norms. Alternatively, a stress and coping perspective on cross-border ties suggests potentially countervailing adverse impacts of these connections on alcohol use. We used data from the 2002/2003 National Latino and Asian American Study (NLAAS) (n = 1,641/1,630 Asian and Latino origin respondents, respectively). We first estimated the association between age at migration (child/adolescent versus adult migrant) and any past-year alcohol use. We subsequently tested the interaction between age at migration and two measures of cross-border connections. All models were stratified by region of origin and gender. For Latin American-origin women, cross-border ties were associated with increased risk of past-year alcohol use among those who migrated early in life. In contrast, Asian-origin men and women who migrated as adults and had contact with family and friends abroad had the lowest predicted probabilities of past-year alcohol use. The results among Asians support the idea that cross-border ties may be alternative influences on health behavior outcomes, particularly for adult migrants. Overall, we find qualified support for both transnational and assimilationist perspectives on alcohol use behaviors among US immigrants – as well as the interaction between these two frameworks. The joint influences of cross-border ties and age at migration were observed primarily for immigrant women, and not always in expected directions. We nevertheless urge future research to consider both US and country of origin influences on a wider range of health and health behavior outcomes for immigrants, as well as the potential intersection between US and cross-border connections.

Evidence suggests that retail investors who invest in individual stocks are, in the long run, largely outperformed by market indexes such as the MSCI World. While some turn to exchange traded funds (ETFs) to invest in such market indexes, few migrate completely to ETFs. This study aims to shed light on the rationale behind retail investors' partial and complete migration from stocks to ETFs.

Drawing from the pull-push-mooring framework, a qualitative study (N = 21) informs a quantitative study (N = 282) by following established mixed methods guidelines. This study develops propositions for partial and complete migration intention to ETFs.

Results reveal that perceived investment possibilities, perceived risk reduction, perceived administrative effort, perceived expensiveness and monetary loss costs influence the migration from stocks to ETFs. This study shows that three configurations of perceptions result in partial migration intention and one configuration results in complete migration intention.

This study explains why some migrate partially from stocks to ETFs and others migrate completely. Findings show that both migration behaviors are subject to the same perceptions, but the configurations that form the behaviors are different. While only some identified perceptions must be present for a partial migration, all of them must be present for a complete migration, as it requires retail investors to sell their stocks and accept the costs incurred to invest in ETFs instead.

Since Poland's accession to the European Union in 2004, migration from Poland to the UK has increased substantially. These migrants are generally young and highly educated, and are migrating for reasons of economic improvement and self-fulfilment. Many are women migrating independently, an emerging trend in migration in general. Information behaviour research around migration has tended to focus on populations such as refugees; less research has been done on the information behaviour of economic migrants. This paper, therefore, investigates the role of information in the migration experience of young Polish women in the UK.

This study takes an interpretivist, constructionist perspective. An exploratory study was conducted, involving expert and pilot interviews and analysis of secondary data. In the main study, 21 participants were interviewed using a semi-structured technique. Data were analysed thematically.

The paper provides insights into the information behaviour and experience of this migrant group. They were found to be confident and successful information users, partly because their migration was planned, their language skills were high and cultural differences from their host country were not substantial. Weak ties were an important source of information. The paper contextualises these findings against previous research on migration in information science, and presents a model of the underlying factors shaping the relationship between migration and information behaviour.

The paper examines the migration experience of a relatively understudied group, drawing attention to a broader range of experience and demonstrating that a wider conceptualisation of migration is required in information behaviour. It presents a model of key factors shaping information behaviour around migration, which is relevant not only to the information field, but also to a wider range of areas. It also delivers practical recommendations for migrants and those working with them.

A general framework for mobile Web services ‐ which are Web services with the ability to migrate from one host to another ‐ is proposed. In this framework, a mobile Web service is composed of a combination of a BPEL process description, service components to be carried, and migration behavior descriptions using simple but expressive rules. The semantics of the descriptions are defined using Mobile Ambients, namely, a formal model of concurrent mobile processes. With this framework, it is thus possible to add or change migration behaviors without having to modify the BPEL process.

The purpose of this paper is to ensure power efficiency in wireless sensor networks (WSNs) through a new framework-oriented middleware, based on a biologically inspired mechanism that uses an evolutionary multi-objective optimization algorithm. The authors call this middleware framework multi-objective optimization for wireless sensor networks (MONet).

In MONet, the middleware level of each network node autonomously adjusts its routing parameters according to dynamic network conditions and seeks optimal trade-offs among performance objectives for a balance of its global performance. MONet controls the cooperation between agents (network nodes) while varying transmission paths to reduce and distribute power consumption equitably on all the sensor nodes of network. MONet-runtime uses a modified TinyDDS middleware platform.

Simulation results confirm that MONet allows power efficiency to WSN nodes while adapting their sleep periods and self-heal false-positive sensor data.

The framework implementation is lightweight and efficient enough to run on resource-limited nodes such as sensor nodes.

For decades, northern Thailand has been a hub for migration in the Greater Mekong Sub-region, particularly for migrants from Myanmar. HIV prevalence among Myanmar/Burmese migrants is higher than in the general Thai population. This study aims to focus on Shan migrants living with HIV in Chiang Mai, the metropolitan centre of northern Thailand and to examine two related aspects: migrants’ sexual risk behaviour and their HIV knowledge and beliefs. The study aims to understand circumstances in which mobility increases HIV risk behaviour and prevalence.

Using a qualitative study, the authors conducted in-depth interviews in 2017 with 43 HIV-infected Shan migrants (21 males and 22 females), and 29 health-care providers who work in district hospitals in Chiang Mai.

The authors found that social and economic vulnerability associated with migration, and AIDS-related mortality, increased migrants’ likelihood of having multiple serial partners. Confusion about HIV symptoms, stigmatization of HIV positive women and low risk perceptions, particularly among men, increased their risk behaviours.

To the best of the authors’ knowledge, this paper is the first to study the way of life, sexual behaviour and HIV knowledge and beliefs of Shan Migrants from Myanmar Living with HIV in Thailand.

The health challenges that characterise most of the migrants' urban slums raises a lot of concern for their well-being. Health-seeking behaviour becomes an important step towards maintaining a healthy life. The importance of contextual issues is necessary to help meet specific community health needs and programmes. Therefore, this study aims to bridge the knowledge gap by investigating health-seeking behaviour disparity among rural–urban labour migrant's slum dwellers before and after migration to the urban slums of Madina in the Greater Accra Region, Ghana.

The author used explanatory sequential approach of research investigation. Questionnaire and interview guides were used to collect data from the respondents however, in the absence of an existing reliable sampling frame, the various communities were selected by the use of cluster sampling proportional to size. At the second stage, a simple random sampling was used to select the various household heads. A total of 241 questionnaires were retrieved from the respondents representing a response rate of 100%. The author used purposive sampling technique to conduct eight in-depth interviews and six key informants' interviews.

The author found various discrepancies in many of the activities that could fulfil substantial health-seeking behaviour in the slum as compared to migrant's places of origin. The reason for coming to the slum amidst many settlements needs and low education background are the factors that accounted for this. This study, therefore, contradicts the proposition held by the health belief model. It is, therefore, important to note that contextual issues are key, in this case, rural–urban migrant slums present a different dynamic that must be taken into account when designing health programmes for such settings.

Many, if not all the, studies on health-seeking behaviour have focused on urban slums without taking into account urban migrants' slums. Such a failure to take into account the variations of the health needs of migrants' urban slum settings can eventually lead to a mismatch of health programmes meant to address their challenges. Therefore, this study brings to the fore such variations that must be taken into account when designing health programmes. The study also indicates that even with the same people, there were disparities in terms of health-seeking behaviour in the slum and at places of origin.

This article explores the migration intentions (MIs) embedded in population movements from rural to urban areas in Bangladesh. In this country, urban-centric development policies have made cities epicentres of commerce and industrialisation, offering significant employment and livelihood opportunities. This rapid transformation has generated several socio-psychological factors that are influencing the willingness of rural populations to migrate to cities for better jobs, lifestyles and services.

The present study adopted the theory of planned behaviour (TPB) as a conceptual model to assess the behavioural and psychological factors underlying MIs.

The results of the structural equation modelling (SEM) indicate that MIs are mainly influenced by subjective norms (SN) and, to a lesser extent, attitudes towards migration (ATM) and perceived behavioural control (PBC).

The analysis drew on an original dataset built through interviews with migrants from rural areas employed in the ready-made garment (RMG) industry in four selective areas of the Metropolitan City of Chittagong.

The evolution in developed countries has taken a role in global warming and natural disasters such as flash flood, El-Nino, earthquake and groundwater contamination. The underground storage tank leakage problems and spillage of hydrocarbon liquid leading to the contamination of non-aqueous phase liquids (NAPLs) into the groundwater could reduce the quality of groundwater. This chapter is intended to investigate the behaviour and the pattern of NAPL migrations in double-porosity soil under vibration and intact conditions. The experimental model is developed by using kaolin soil type S300 and toluene as NAPLs. The kaolin soil was mixed with 25% of moisture content to produce kaolin granules in the soil column and vibrate under 0.98 Hz of frequency within 60 seconds. As a result, both specimen liquids completely migrated to the bottom of soil column: sample 1 has higher permeability compared to sample 2. This is due to the fracture in double-porosity soil under vibration effect and loosened the soil structure in sample 1 compared to good intact soil sample 2 with stronger and compact soil structure. In conclusion, this study proves that the dangerous hydrocarbon NAPL migration in fractured double-porosity soil has very harmful effect on the environment and groundwater resources.
