Molecular sex-typing in shorebirds: a review of an essential method for research in evolution, ecology and conservation

Knowing the correct sex of individuals is essential both for research in evolutionary ecology and for practical conservation. Recent molecular advances have produced cheap, quick and reliable methods for sexing birds including chicks, juveniles, immatures and adults. Shorebird researchers have not yet fully utilised these advances. Here we provide an overview of work in this area to date with two objectives: (i) to review the major applications of molecular sexing and findings of shorebird research so far, and (ii) to provide an essential guide on how to carry out molecular sexing using current methods whilst avoiding methodological pitfalls. We encourage shorebird researchers to make better use of molecular sex-typing techniques in studies of conservation, migration, foraging ecology and breeding behaviour.

Practical field use of eye-tracking devices for consumer research in the retail environment

Eye-tracking equipment is now affordable and portable, making it a practical instrument for consumer research. Engineered to best analyze gaze on a plane (e.g., a retail shelf), both portable eye-tracking glasses and computer monitor–mounted hardware can play key roles in analyzing merchandise displays to better understand what consumers view. Researchers and practitioners can use that information to improve the sales efficacy of displays. Eye-tracking hardware was nearly exclusively used to investigate the reading process but can now be used for a broader range of study, namely in retail settings. This article presents an approach to using glasses eye tracker (GET) and light eye tracker (LET) eye-tracking hardware for applied consumer research in the field. We outline equipment use, study construction, data extraction as well as benefits and limitations of the technology collected from several pilot studies.

Spoken mathematics as a distinguishing characteristics of mathematics classrooms in different countries

This paper reports research into the occurrence of spoken mathematics in some well-taught classrooms in Australia, China (both Shanghai and Hong Kong), Japan, Korea and the USA. The analysis distinguished one classroom from another on the basis of public “oral interactivity” (the number of utterances in whole class and teacher-student interactions in each lesson) and “mathematical orality” (the frequency of occurrence of key mathematical terms in each lesson). Our concern in this analysis was to document the opportunity provided to students for the oral articulation of the relatively sophisticated mathematical terms that formed the conceptual content of the lesson. Classrooms characterized by high public oral interactivity were not necessarily sites of high mathematical orality. The contribution of student-student conversations also varied significantly. Of particular interest are the different learning theories implicit in the role accorded to spoken mathematics in each classroom.

Development aid and growth in transition countries

Empirical studies normally analyze diverse and heterogeneous groups of countries, producing very mixed evidence on the effectiveness of development aid in promoting growth. We focus on whether aid promotes economic growth in transitional economies. We find that aid, on average, has had a positive impact on growth for this specific group of countries. This result is robust to samples, estimators, and the use of alternate instruments to address endogeneity. Aid effectiveness is not conditional on good policy and there is little evidence of non-linear growth effects arising from aid.

International study of perceived neighbourhood environmental attributes and Body Mass Index: IPEN Adult study in 12 countries

BACKGROUND: Ecological models of health behaviour are an important conceptual framework to address the multiple correlates of obesity. Several single-country studies previously examined the relationship between the built environment and obesity in adults, but results are very diverse. An important reason for these mixed results is the limited variability in built environments in these single-country studies. Therefore, the aim of this study was to examine associations between perceived neighbourhood built environmental attributes and BMI/weight status in a multi-country study including 12 environmentally and culturally diverse countries. METHODS: A multi-site cross-sectional study was conducted in 17 cities (study sites) across 12 countries (Australia, Belgium, Brazil, China, Colombia, Czech Republic, Denmark, Mexico, New Zealand, Spain, the UK and USA). Participants (n = 14222, 18-66 years) self-reported perceived neighbourhood environmental attributes. Height and weight were self-reported in eight countries, and measured in person in four countries. RESULTS: Three environmental attributes were associated with BMI or weight status in pooled data from 12 countries. Safety from traffic was the most robust correlate, suggesting that creating safe routes for walking/cycling by reducing the speed and volume of traffic might have a positive impact upon weight status/BMI across various geographical locations. Close proximity to several local destinations was associated with BMI across all countries, suggesting compact neighbourhoods with more places to walk related to lower BMI. Safety from crime showed a curvilinear relationship with BMI, with especially poor crime safety being related to higher BMI. CONCLUSIONS: Environmental interventions involving these three attributes appear to have international relevance and focusing on these might have implications for tackling overweight/obesity.

Economic edifice, urbanisation and rural education in developing countries

The nexus between economic edifice, urbanisation and education is a somewhat understudied area in the academic literature. This applies especially to the urban-rural nexus and its impact on transition in economic edifice, which are especially pronounced in developing countries. This article addresses some selected consequences of urbanisation on education in developing countries within a context of transition in economic edifice. It is argued that transitions in economic edifice are for rural populations at times unrestrained and precipitous. It is further argued that the transition economic edifice impacts on social, economic and personal interests of not only the school-aged population, but also of the working and retired population. Against this background, this article discusses factors relating to effects of urbanization within a context of urbanisation and urbanisation theories, including transition in economic edifice, globalization, employment and employability, and vocationalisation of education. In conclusion opportunities and challenges for education in the context of transforming an economic structure in rural areas in a contemporary context is brought to the fore.

Factorial invariance of the DASS-21 among adolescents in four countries

The use of scales to measure constructs in populations or contexts other than that in which they were established is highly controversial. Despite this, the use of scales without reference to "local" psychometric data is still widespread. In this study we examined the factor structure of the short 21-item form of the Depression, Anxiety, and Stress Scales (DASS-21), when it was applied to adolescent samples recruited from high schools in Australia (N = 371), Chile (N = 448), China (N = 558), and Malaysia (N = 388). Multigroup confirmatory factor analyses revealed that the purported three-factor structure of the DASS-21 was supported in each location with structural invariance across locations. While convergent and divergent validity studies are required to support this finding, the DASS-21 appears to be suitable for use with adolescents in these locations.

How the observed create ethical dilemmas for the observers: experiences from studies conducted in clinical settings in the UK and Australia

Observational research has a history of controversy, particularly when the research is conducted in a clinical setting. Existing ethical approval processes focus on protecting participants and the researcher's responsibilities, in particular where vulnerable populations are concerned. In this study, the authors explored the less overt and often understated ethical challenges that can arise when conducting observational research in a clinical setting. Reflecting on two recent studies conducted in different clinical settings, the authors described the challenges of blurring role boundaries, the risk of collecting redundant data, and the impact of reverse power relationships between researchers, clinicians, and managers. From their experiences, the authors suggested that the preparatory work undertaken with clinicians and managers onsite, which typically focuses on how the researchers will maintain the ethical robustness of the research and protect the rights of participants and the vulnerable, should also highlight the sometimes overlooked ethical issues associated with participatory research. This can help ensure that participants and managers understand the scope and limitations of the research, and consider the ways in which the observed can influence the researcher and the findings.

Doing educational research in Bangladesh: challenges in applying Western research methodology

Research methods are closely linked to specific cultures (Kee, 2004). Recognition of cultural values in the knowledge generation process is important if researchers are to produce culturally diverse interpretations of reality that facilitate meaningful progression. Asian scholars often depend on Western theories for understanding issues and creating knowledge in their own contexts (Papoutsaki, 2006). Many scholars relate this influence of the West on the non-West to neocolonization (Nguyen et al., 2009), neo-imperialism (Balogh, 1962) and globalization (Rizvi, 2004; Campbell, 2012). Scholars also see this influence as a unidirectional cultural flow, from 'the West' to 'the Rest' (Rizvi, 2004, p. 159). Such Western influences on knowledge-generating practices often pose challenges for researchers fro1n non-Western, particularly Asian, contexts when they employ Western methodologies in their own contexts. These challenges are embedded in differences in cultural values, beliefs and norms, as well as differences in orientation to research, because each society is unique in character and has specific knowledge needs that are culturally appropriate. Societal and local knowledge is, essentially, a contributory factor if research is to be locally appropriate and globally acceptable (Ma Rhea, 2004).

Article 27(3)(b) TRIPS and plant variety protection in developing countries

In comparison with industrialised countries, agriculture in developing countries accounts for a substantial share of GDP and involves a substantial sector of small-holders and traditional agriculturalists. In view of these differences, the biotechnology clause of Article 27.3.b TRIPS with its requirement of plant variety protection either by patents or an effective sui generis system or a combination of the two has been controversial. However, developing countries have made surprisingly little use of the freedom to design their own systems in this field. Instead, there has been a surge in UPOV membership among developing countries and some have gone as far as introducing patent protection for plant varieties. Such countries now have to consider the same exclusions and exceptions to patenting that are normally discussed in countries with much more advanced biotechnology industries. The chapter examines the scope for the use of orde public considerations under Article 27.2 TRIPS, of exclusions for research and experimental purposes under Article 30 TRIPS, compulsory licensing under Article 31 TRIPS as well as the advantages of a specific breeding exemption and it briefly comments on the various sui generis options. While liberal interpretations of the TRIPS exceptions remain possible, the chapter concludes that the majority of developing countries will be better off in more creatively using the freedom to develop sui generis systems suitable for their local conditions rather than struggling to introduce TRIPS conform ‘limited exceptions’ to patent protection for plant varieties.

Perceived neighborhood environmental attributes sssociated with walking and cycling for transport among adult residents of 17 cities in 12 countries: the IPEN study

INTRODUCTION: Prevalence of walking and cycling for transport is low and varies greatly across countries. Few studies have examined neighborhood perceptions related to walking and cycling for transport in different countries. Therefore, it is challenging to prioritize appropriate built-environment interventions. OBJECTIVES: The aim of this study was to examine the strength and shape of the relationship between adults' neighborhood perceptions and walking and cycling for transport across diverse environments. METHODS: As part of the International Physical activity and Environment Network (IPEN) adult project, self-reported data were taken from 13,745 adults (18-65 years) living in physically and socially diverse neighborhoods in 17 cities across 12 countries. Neighborhood perceptions were measured using the Neighborhood Environment Walkability Scale, and walking and cycling for transport were measured using the International Physical Activity Questionnaire-Long Form. Generalized additive mixed models were used to model walking or cycling for transport during the last seven days with neighborhood perceptions. Interactions by city were explored. RESULTS: Walking-for-transport outcomes were significantly associated with perceived residential density, land use mix-access, street connectivity, aesthetics, and safety. Any cycling for transport was significantly related to perceived land use mix-access, street connectivity, infrastructure, aesthetics, safety, and perceived distance to destinations. Between-city differences existed for some attributes in relation to walking or cycling for transport. CONCLUSIONS: Many perceived environmental attributes supported both cycling and walking; however, highly walkable environments may not support cycling for transport. People appear to walk for transport despite safety concerns. These findings can guide the implementation of global health strategies.

The impact of external forces on cartel network dynamics: direct research in the diamond industry

This paper describes the impact of external environmental forces on cartel networks. Using a case research approach, this report examines two leading business networks within one industry, over time. The results suggest that (a) bargaining power of intermediaries increases with the advent of new and powerful actors, (b) process activities that cartels previously controlled are being outsourced to new actors sometimes based in developing countries, (c) other actors are acquiring resources once dominated by a cartel, (d) external forces triggered by the illegal diamond trade, such as international regulatory constraints, no longer favour cartels like De Beers, and (e) over time, these and additional environment factors are forcing actors like De Beers who perform rigid process activities to become more flexible. For example, forces are moving cartels which relied previously on hand-picked intermediaries in highly controlled networks to market their products to adopt a flexible market-focused expansion of operations in retail contexts.

Global virtual engineering teams (GVETs): a fertile ground for research in Australian construction projects context

Implementation of global virtual engineering teams (GVETs) commenced since at least two decades ago, but construction has been behind other industries in terms of harnessing this new paradigm. Nevertheless, GVETs are receiving increasing attention within the construction context due to numerous potential benefits they can bring about for the projects. On the other hand, the research about GVETs in Australia is still in its embryonic stages. Australian scholars noticeably have paid scant attention to GVETs in comparison to their colleagues in other developed countries. This paper assumes the process of implementation of a GVET as an isolated project. The study then highlights the well-known main areas of necessary knowledge for managing a GVET project within the construction context based on a project lifecycle approach. Recognizing the weaknesses of existing literature, the paper sets out an agenda for further research within Australian construction projects.

A framework for electronic commerce research in small to medium-sized enterprises

It is believed that the recent emergence of electronic commerce (e-commerce) in the early '90s could provide different opportunities to small to medium-sized enterprises (SME's) in overcoming part of their technological, environmental, organizational, and managerial inadequacies. However, recent research portrays a gloomy picture about e-commerce uptake and use in SME's. Therefore, the implication here is twofold. Initially, there is a need to generate more e-commerce research that could penetrate much deeper into main impending issues pertaining to the SME’s in their potential uptake and use of e-commerce. On the other hand, e-commerce is characterized of being embryonic but growing very fast and fragmented across the different disciplines, which makes the task of capturing its different perspectives a very complex one. The preceding two implications represent the greatest challenge for researchers and professionals interested in undertaking e-commerce research in SME’s. In line with the above implications, the first objective of this research aims at capturing the different e-commerce perspectives from the SMEs' point of view, and the second objective aims at capturing the e-commerce perspective from the theoretical and the methodological point of view. Addressing the preceding implications in this research could shed some light into some of the gray areas in the e-commerce research in SMEs.
