This paper describes efforts by the Institute of Geography and Earth Sciences at the University of Wales, Aberystwyth, to develop effective strategies with which to develop students’ skills in communications and information technology (C&IT). The strategy adopted was to develop these skills within modules that tackle traditional earth science subjects rather than devise a specific skills development module. Two modules were utilised: Geohazards and the Malta Fieldcourse, which specified the achievement of C&IT skills as key objectives. The results of the first year’s experiment were surprising. Students on the Geohazards module, who received extensive practical instruction in C&IT skills, did not demonstrate appreciable attainment of C&IT skills. In contrast, many students on the Malta Fieldcourse, who received no practical C&IT instruction, created Web pages for assessment. The reasons for these results were evaluated and alterations made to both modules, mainly in respect of the learning environment. Results in 1998 were dramatically improved and demonstrate the importance of creating and maintaining an experiential learning environment to encourage students to develop and demonstrate C&IT skills.

A theoretical extension of Berger, Webster, Ridgeway, and Rosenholtz's (1986) theory of status cues is proposed, which argues that task cues which contradict expectations based on categorical cues may reduce or overcome the effects of the latter on status processes. Possible mechanisms for these differential effects were suggested. Two studies examined the relative impact of verbal fluency and ethnic accent on perceptions of competence, and on acceptance of influence in a group task. In Study 1 tape-recorded passages read by Greek- and Anglo-Australian speakers were judged by independent groups on rating scales which tapped three dimensions: intelligence, competence/education, (referred to as status dimensions), and solidarity. Fluency of speaker affected raters' judgments of confidence and intelligence, but not solidarity; ethnic identity of speaker affected only ratings of intelligence. Tape

This chapter aims to review evidence of the relationships between dog ownership, dog walking and overall walking and the factors associated with dog walking. It reviews the evidence using a social ecological framework. The chapter finds that dog ownership and dog walking are associated with higher levels of walking. A number of social ecological factors are associated with dog walking. Motivation and social support provided by the dog to walk and a sense of responsibility to walk the dog are associated with higher levels of dog walking. Positive social pressure from family, friends, dog owners and veterinarians is also associated with higher levels of dog walking. Built and policy environmental characteristics influence dog walking, including dog-specific factors such as access to local attractive public open space with dog-supportive features (off-leash, dog waste bags, trash cans, signage), pet-friendly destinations (cafes, transit, workplaces, accommodation) and local laws that support dog walking. Large-scale intervention studies are required to determine the effect of increased dog walking on overall walking levels. Experimental study designs, such as natural and quasi-experiments, are needed to provide stronger evidence for causal associations between the built and policy environments and dog walking. Given the potential of dog walking to increase population-levels of walking, urban, park and recreational planners need to design neighbourhood environments that are supportive of dog walking and other physical activity. Advocacy for dog walking policy-relevant initiatives are needed to support dog walking friendly environments. Health promotion practitioners should make dog walking a key strategy in social marketing campaigns.

The purpose of this chapter is to review how well walking interventions have increased and sustained walking, and to provide suggestions for improving future walking interventions. A scoping review was conducted of walking interventions for adults that emphasised walking as a primary intervention strategy and/or included a walking outcome measure. Interventions conducted at the individual, community, and policy levels between 1990 and 2015 were included, with greater emphasis on recent interventions. Walking tends to increase early in interventions and then gradually declines. Results suggest that increased walking, and environmental-change activities to support walking are more likely to be sustained when they are immediately followed by greater economic benefits/time-savings, social approval, and/or physical/emotional well-being. Adaptive interventions that adjust intervention procedures to match dynamically changing environmental circumstances also hold promise for sustaining increased walking. Interventions that incorporate automated technology, durable built environment changes, and civic engagement, may increase cost-efficiency. Variations in outcome measures, study duration, seasons, participant characteristics, and possible measurement reactivity preclude causal inferences about the differential effectiveness of specific intervention procedures for increasing and sustaining walking. This review synthesises the effects of diverse walking interventions on increasing and sustaining walking over a 25-year period. Suggestions are provided to guide future development of more effective, sustainable walking interventions at the population level.

Uncertainty-identity theory serves as our guiding theoretical framework to explore subjective uncertainty, especially uncertainty about self and identity, and the ways in which communication within groups provides valuable social identity information to group members as a means to manage subjective uncertainty.

We review and synthesize research in communication science and social identity theory, specifically uncertainty-identity theory, to compare diverse understandings of uncertainty and the identity-shaping function of communication within groups.

Uncertainty inherent in dyadic interactions has received extensive attention in communication science. However, the identity-defining function of communication that flows within and between groups as a means to resolving uncertainty about subjectively important matters has received little attention in both social psychology and communication science.

We explore how communication that flows from in-group sources (e.g., leaders) serves to shape a shared reality and identity for group members while providing a framework for self-definition. We propose an agenda for future research that would benefit from an articulation of the importance of communication in the shaping and management of identity-uncertainty.

Uncertainty arousing rhetoric by influential in-group sources, such as leaders and the media can have serious implications for intergroup relations, as uncertain individuals seek distinctive and tight-knit groups and autocratic leaders under conditions of heightened uncertainty. The role that communication plays in shaping clear and distinct identities as a panacea for identity-uncertainty has implications for the intragroup normative structure of the group and for intergroup relations.

Assesses the effect of an international business person′s accent on Guatemalan subjects′ perception of the business person′s effectiveness, credibility, competence, friendliness, as well as the Guatemalan subject′s intentions to buy. Graduate students at a Guatemalan university listened to tape recordings of three presenters speaking Guatemalan Spanish and three presenters speaking Spanish with a foreign accent. The findings suggest that, for the Guatemalan audience, a sales pitch in Guatemalan Spanish evoked more favourable judgements on all measured dimensions than the same sales pitch in foreign accented Spanish. Females, however, evaluated the Guatemalan Spanish presenters more positively and evaluated the foreign accented presenters more negatively than their male counterparts.

In a previous article we have called attention to the danger of eating tinned and bottled vegetables which have been coloured by the addition of salts of copper and we have urged upon the public that no such preparations should be purchased without an adequate guarantee that they are free from copper compounds. Copper poisoning, however, is not the only danger to which consumers of preserved foods are liable. Judging from the reports of cases of irritant poisoning which appear with somewhat alarming frequency in the daily press, and from the information which we have been at pains to obtain, there can be no question that the occurrence of a large number of these cases is to be attributed to the ingestion of tinned foods which has been improperly prepared or kept. It is not to be supposed that the numerous cases of illness which have been ascribed to the use of tinned foods were all cases of metallic poisoning brought about by the action of the contents of the tins upon the metal and solder of the latter. The evidence available does not show that a majority of the cases could be put down to this cause alone; but it must be admitted that the evidence is in most instances of an unsatisfactory and inconclusive character. It has become a somewhat too common custom to put forward the view that so‐called “ptomaine” poisoning is the cause of the mischief; and this upon very insufficient evidence. While there is no doubt that the presence in tinned goods of some poisonous products of decomposition or organic change very frequently gives rise to dangerous illness, so little is known of the chemical nature and of the physiological effects of “ptomaines” that to obtain conclusive evidence is in all cases most difficult, and in many, if not in most, quite impossible. A study of the subject leads to the conclusion that both ptomaine poisoning and metallic poisoning—also of an obscure kind—have, either separately or in conjunction, produced the effects from time to time reported. In view of the many outbreaks of illness, and especially, of course, of the deaths which have been attributed to the eating of bad tinned foods it is of the utmost importance that some more stringent control than that which can be said to exist at present should be exercised over the preparation and sale of tinned goods. In Holland some two or three years ago, in consequence partly of the fact that, after eating tinned food, about seventy soldiers were attacked by severe illness at the Dutch manœuvres, the attention of the Government was drawn to the matter by Drs. VAN HAMEL ROOS and HARMENS, who advocated the use of enamel for coating tins. It appears that an enamel of special manufacture is now extensively used in Holland by the manfacturers of the better qualities of tinned food, and that the use of such enamelled tins is insisted upon for naval and military stores. This is a course which might with great advantage be followed in this country. While absolute safety may not be attainable, adequate steps should be taken to prevent the use of damaged, inferior or improper materials, to enforce cleanliness, and to ensure the adoption of some better system of canning.
