Thermal comfort in outdoor places a multicultural perception

The outdoor places are receiving more importance being contributing in the social cohesion and sustainability within societies. Providing comfortable sustainable urban places is an important factor affecting their success especially in multicultural areas where climatic conditions are perceived differently according to the diversity of users. Different design elements such as design form proved to be able to improve the outdoor thermal comfort. However, the integration of the climate dimension in the design process of outdoor places is lacking due to insufficient interdisciplinary work between urban climatology, and urban design. The main aim of the research is to examine the influence of cultural and climatic background on users’ thermal sensation and comfort within the same context. The methodology of the research is provided through quantitative analysis of a case study in Melbourne, Australia as one of the global cities characterized by the diversity and plurality of its population. The case study approach is adopted in order to examine the users’ thermal comfort within its contextual variables. Multiple sources of evidence such as climate measurements, questionnaires and observations are used to ensure the validity of results. The findings are to contribute to the quality and equality of design for outdoor urban places.

Effect of personal and cultural diversity on outdoor thermal comfort perception

The urban squares are the gathering places where people interact with each other. Therefore, they are seen as important places contributing in the integration and social cohesion within societies. To ensure equality in urban places, designers are to take into considerations the need of the diverse nature of different users. This task is hard especially in global cities where populations are characterized by their cultural plurality. To ensure the creation of successful urban places, the designer is to take the comfort of users into consideration. However, the outdoor thermal comfort is not easily assessed as it examines the climatic and personal variables for users. This paper aims to contribute in assessing the thermal comfort for users of different personal and cultural background in Melbourne city, Australia as one of the global cities characterized by the diversity and plurality of its population due to migration. A case study approach is adopted to examine the users’ thermal comfort within the contextual variables of Federation Square. Multiple sources of evidence such as climate measurements, observations and questionnaires will be used to ensure the validity of results. The findings are to contribute in the quality and equality of design for outdoor urban places in multicultural cities.

Effect of thermal adaptation on outdoor comfort perception

Thermal comfort in outdoor places has proven to have a strong relationship with their users’ attendance and behaviour [1]. Creating comfortable places is therefore to be considered a crucial part of the design process, as taking it into consideration help increasing the social integration between people and therefore fosters sustainability within cities [2]. With the increasing number of migrants within global cities, a new challenge has been facing thermal comfort studies. This challenge is related to the different cultural and climatic origins of those migrants and how they can adapt to the new climatic conditions they are to move in. This paper aims to explore the impact of thermal comfort adaptation on users’ thermal perception in multicultural cities. Consequently, a quantitative field study is applied in Melbourne city, Australia in order to investigate peoples’ outdoor thermal comfort. The analyses were based upon the measurement of climatic parameters that were monitored simultaneously with a questionnaire to determine users’ thermal comfort perception in relation to their time spent in the city. The findings of thermal comfort investigations could be applied into improving the quality of urban areas within global cities and therefore promote the integration within individuals in those societies.

Adolescents' perception of the relationship between movement skills, physical activity and sport

Movement skill competence is important to organised youth physical activity participation, but it is unclear how adolescents view this relationship. The primary aim of this study was to explore adolescents’ perception of the relationship between movement skills, physical activity and sport, and whether their perceptions differed according to extent of participation in organised physical activities. We recruited 33 (17 male) Grade 11 and 12 students (aged 16 to 18) from two secondary schools in Australia. Focus groups were allocated according to whether or not students participated in organised physical activity, where ‘organised activity’ was defined as activity which involved regular classes, training or competition, was reasonably structured or formal, or had a teacher, instructor or coach. There were three all-male ‘organised’ groups, one mixed-gender ‘organised’ group and one all-female ‘not-organised’ group. Students were asked about their attitudes towards physical activity and sport, the relationship between childhood skill proficiency and later physical activity and their perceptions of the appropriate time taken to learn movement skills. Group discussions lasted for approximately 50 minutes, were recorded and were then transcribed verbatim. Transcripts were read using a constant comparison method, in which quotes were continually compared to other quotes. A thematic analysis was conducted in which the transcripts were analysed inductively. Participation in organised sport had no bearing on opinions regarding whether lack of childhood skill development would negatively impact latter participation. It did, however, subtly influence opinions regarding whether skill could be successfully acquired later in life. When asked whether not having well-developed skills as a child would negatively impact on participation in sport/physical activity later in life, the response was mixed, but this was not related to their involvement in organised sport or activities. Students who believed early skill proficiency related to subsequent activity thought this was due to skill ability and motivation. An alternate view was that subsequent activity did not need to be based on skill proficiency; also, one’s environment might change, resulting in differing opportunities/constraints. Students felt skills could be learnt at any time in life (dependent on motivation), but that learning skills at a younger age would be easier and that skills learnt later would not be as developed. Fear of failure was identified as a barrier to learning when older. We conclude that motivation towards participation in sport and physical activity is affected by adolescents’ perception of their own movement skill ability. Therefore, developing children’s actual and perceived movement skills may help to increase adolescent physical activity. Since those with intrinsic achievement orientations were not as inclined towards organised activity, we may also need to provide physical activity options that resonate with intrinsic achievement motivations.

Health labelling can influence taste perception and use of table salt for reduced-sodium products

Objective : To investigate the effect of front-of-pack labels on taste perception and use of table salt for currently available and sodium-reduced soups.

Design : Within-subject design.

Setting : Sensory laboratory.

Subjects : Participants (n 50, mean age 34·8 (sd 13·6) years) were randomly served nine soups (250 ml each) across 3 d. Servings differed in: (i) health label (i.e. no health label, reduced-salt label or Heart Foundation Tick); and (ii) sodium reduction (no reduction – benchmark, 15 % less sodium or 30 % less sodium). Before tasting, participants rated their expected salt intensity and liking. After tasting, participants rated their perceived salt intensity and liking, after which they could add salt to the soup to make it more palatable.

Results : Reduced-salt labels generated a negative taste expectation and actual taste experience in terms of liking (P < 0·05) and perceived saltiness (P < 0·05). Perceived saltiness of sodium-reduced soups decreased more (P < 0·05), and consumers added more salt (P < 0·05), when soups carried the reduced-salt label. The tick logo and soups without health labels had no such influence on taste perception.

Conclusions : Emphasizing salt reduction by means of a front-of-pack label can have a negative effect on taste perception and salt use, especially when consumers are able to taste differences between their regular soup and the sodium-reduced soup. Overall health logos which do not emphasize the reduction in salt are less likely to affect perceived salt intensity and therefore are viable solutions to indicate the healthiness of sodium-reduced products.

How do drug and alcohol use relate to parental bonding and risk perception in university students?

Alcohol and drug use are major health concerns on university and college campuses. It has previously been found that parental rearing patterns are related to the frequency of substance use. Further, perceptions that drug use is dangerous have been found to be related to less substance use. However, little research has directly examined the impact of parental rearing patterns on substance use by university students, and no research has examined the effects of both risk perception and parenting on substance use. Therefore, this research surveyed the frequency and extent of alcohol, cigarette and illicit drug use by students (N = 336) at a Canadian university residence, classes and health services and examined the relationship between the results with parental bonding and risk perception. It was found that “affectionless control” parenting patterns in the mother, but not the father, were related to greater drinking and drinking problems and to the use of illicit substances. Lower perceptions of risk were related to greater use of alcohol, cigarettes, cannabis and other illicit substances. Unexpectedly, there was little relationship between parental rearing and risk perceptions, suggesting that there are other avenues whereby parenting leads to greater alcohol use. Implications are discussed.

Biopsychosocial correlates of weight status perception in Australian adolescents

This study examined the utility of the biopsychosocial model to predict accuracy of weight status perception among Australian adolescents. The factors included in this framework were: age, gender, and BMI-z (biological factors); satisfaction with body weight and shape (psychological factors); socioeconomic status, peer weight (social factors). Cross-sectional data, including measured height and weight, and self-reported weight status, was obtained from 2954 adolescents (mean age = 14.6, 56% male) who participated in the It's Your Move! study. Accuracy of weight status perception was associated with gender, BMI-z, SES, and weight and shape satisfaction. Gender differences in weight status perception were moderated by satisfaction with weight. In boys, weight satisfaction was associated with perceived healthy weight; in girls, it was associated with perceived healthy weight and underweight. Moderately overweight adolescents are most at risk of underestimating their weight status and could benefit from education about the boundaries of the healthy weight range.

Universal housing : Malaysian architect's perception on its implementation

Implementation of Universal Design (UD) in Malaysian built and natural environments is facing some barriers especially in housing. Irrespective of any age and ability, UD is a concept that seeks to positively respond to the needs of access to the physical environment which includes the right to live contentedly in one's house. The aim of this paper is to investigate the perceptions of Malaysian architects toward UD with an emphasis upon housing as a means in identifying the barriers of its implementation. The interview questions focus on perceptions, knowledge and understanding of architects in terms of terminology, legislation and standards, government and professional institute's initiatives and policies on UD. Findings show that among the barriers are confusion in terminology, biased knowledge, and misconceptions of the concept. The ongoing results of the study are presented in the paper together with suggestions for improvements and other implications.
