Is the perception of time pressure a barrier to healthy eating and physical activity among women?

Objectives To describe the proportion of women reporting time is a barrier to healthy eating and physical activity, the characteristics of these women and the perceived causes of time pressure, and to examine associations between perceptions of time as a barrier and consumption of fruit, vegetables and fast food, and physical activity.
Design A cross-sectional survey of food intake, physical activity and perceived causes of time pressure.
Setting A randomly selected community sample.
Subjects A sample of 1580 women self-reported their food intake and their perceptions of the causes of time pressure in relation to healthy eating. An additional 1521 women self-reported their leisure-time physical activity and their perceptions of the causes of time pressure in relation to physical activity.
Results Time pressure was reported as a barrier to healthy eating by 41 % of the women and as a barrier to physical activity by 73 %. Those who reported time pressure as a barrier to healthy eating were significantly less likely to meet fruit, vegetable and physical activity recommendations, and more likely to eat fast food more frequently.
Conclusions Women reporting time pressure as a barrier to healthy eating and physical activity are less likely to meet recommendations than are women who do not see time pressure as a barrier. Further research is required to understand the perception of time pressure issues among women and devise strategies to improve women’s food and physical activity behaviours.

Changing perception of average person's risk does not suffice to change perception of comparative risk

The direct method of assessing “unrealistic optimism” employs a question of the form, “Compared with the average person, what is the chance that event X will occur to you?” It has been proposed that when individuals construct their responses to this question (direct-estimates) they focus much more strongly on estimates of their own risk (self-estimates) than on estimates of the average person's risk (other-estimates). A challenge to this proposal comes from findings that interventions that alter other-estimates also change direct-estimates. Employing a novel intervention technique, we tested the possibility that such interventions may indirectly also change self-estimates and that this is what accounts for their effect on direct-estimates. Study 1 (n = 58) showed that an intervention which was designed to (and did) affect other-estimates also affected self-estimates, while Study 2 (n = 101) showed that it affected direct-estimates. Study 3 (n = 79) confirmed that we could modify the intervention so as to maintain the effect on other-estimates, but eliminate that on self-estimates. Study 4 (n = 112) demonstrated that when this was done, there was no longer any effect on direct-estimates. The findings are consistent with the proposal that direct-estimates are constructed largely just out of self-estimates. Implications for heath education programs are discussed.

Older persons' perception of risk of falling : implications for fall-prevention campaigns

Objectives. We examined older people's attitudes about falls and implications for the design of fall-prevention awareness campaigns.

Methods. We assessed data from (1) computer-assisted telephone surveys conducted in 2002 with Australians 60 years and older in Northern Rivers, New South Wales (site of a previous fall-prevention program; n=1601), and Wide Bay, Queensland (comparison community; n=1601), and (2) 8 focus groups (n=73).

Results. Participants from the previous intervention site were less likely than were comparison participants to agree that falls are not preventable (odds ratio [OR]=0.76; 95% confidence interval [Cl]=0.65, 0.90) and more likely to rate the prevention of falls a high priority (OR=1.31; 95% CI=1.09, 1.57). There was no difference between the groups for self-perceived risk of falls; more than 60% rated their risk as low. Those with a low perceived risk were more likely to be men, younger, partnered, and privately insured, and to report better health and no history of falls. Focus group data indicated that older people preferred messages that emphasized health and independence rather than falls.

Conclusions. Although older people accepted traditional fall-prevention messages, most viewed them as not personally relevant. Messages that promote health and independence may be more effective.

Weight status and perception barriers to healthy physical activity and diet behavior

Background : Physical inactivity and insufficient fruit and vegetable consumption are key risk factors for obesity and noncommunicable diseases. Weight perceptions may affect physical activity and diet behaviors. We report current prevalence estimates of Australian adults meeting recommended levels of leisure-time physical activity (LTPA) (150 min/week or more of at least moderate-intensity physical activity (including walking) on 5 days/week) and fruit (2 servings/day) and vegetable (5 servings/day) consumption for health benefits, by weight status and perceptions.
Methods : We conducted a cross-sectional survey analysis of data for 16 314 adults from the Australian National Health Survey 2004–2005. All variables were collected by self-report. Weighted estimates were age- and gender-specific, and data were analyzed using logistic regression with acceptable weight referent categories, adjusting for covariates.
Results : Among acceptable, overweight and obese adults, the prevalence of LTPA was 26.8, 26.1 and 19.3% for men, and 27.7, 23.7 and 19.7% for women, respectively. Approximately 55 and 15% of adults consumed sufficient fruit servings/day and vegetable servings/day, respectively, and less than 5% of adults met combined LTPA and diet guidelines. Overweight decreased the odds ratio for LTPA among women but not men, and obesity decreased the odds ratio for LTPA among both men and women. Overweight perception conferred odds ratios of 0.83 (95% CI 0.70–0.97, P=0.021) for overweight men, and of 0.74 (95% CI 0.62–0.88, P=0.001) and 0.69 (95% CI 0.59–0.80, P<0.001) for obese men and women, respectively; for LTPA, whereas no significant associations were found for acceptable weight perception. No consistent associations between weight status or perceptions and diet behaviors were found.
Conclusions : Overweight perception may be another barrier to physical activity participation among men and women with excess body weight. Public health strategies might need to focus on overcoming weight perception as well as weight status barriers to adopting healthy physical activity behaviors.

Rogue men and predatory women : female fan's perception of Australian footballers' sexual conduct

The 2004 Australian Football League and National Rugby League seasons started amidst claims made by women about players behaving inappropriately towards them. A raft of allegations surfaced in the media, prompting nationwide debate on the issue of sportsmen and violence. While sport sociologists have made important inroads toward understanding sexual misconduct by male athletes, much of this research appears to focus on the socio-cultural factors informing the perpetrators' actions. This study takes a different approach, analysing the perspectives of female Australian rules football fans to consider gendered narratives of sexual misconduct. Our findings demonstrate that discourses of individualism, along with a mix of socio-cultural and biological arguments, are used by women to reconcile players' misconduct with continuing support of their sport.

Value perception in music information systems

When referring to the value that IS adds to business and provides to consumers, we often (implicitly or explicitly) pertain to monetary value. However, perspectives exist regarding the notion of value which go beyond the monetary significance and maintain a direct influence on businesses and their performance. This paper explores the concept of value, its importance in IS, and the importance of understanding of how IS stakeholders perceive value. The paper focuses on the challenge of studying value in IS -although value manifests in properties of an information system, it can only be experienced and perceived subjectively through sense perception, experience and judgement of the system stakeholders. To address this challenge, the paper suggests the existence of a clearly shifting trend in the perception of IS technology and comments on the social impacts of end-users (consumers) being absorbed into the value-creation process for an information system in the music industry.

Students' perception of an online marketing subject : a qualitative approach

Extant literature supports the growing importance of offering flexible modes of learning delivery in order to meet the needs of a diverse student cohort. The increased use of information and communication technologies (ICT) has lead to an enriched learning experience, but has also posed a number of constraints and challenges for students. Although there is an abundance of research regarding students’ perceptions, attitudes and satisfaction with the online learning environment, most of this is taken from the perspective of the distance education student. The purpose of this qualitative study is to examine these issues from the perspective of a mixed cohort of students (both on and off campus), who are required to complete a core, undergraduate marketing unit exclusively online.

The impact of workload on wellbeing, mental health and depression : a longitudinal study of work perception

This paper explores the relationships between characteristics of the job (workload, control and support) and organizational justice (distributive, procedural, interpersonal and informational) at Time 1, onto three indicators of psychological health at Time 2 (psychological wellbeing, distress and depression). The sample consisted of sworn members of a state-based police force (n=143). Hierarchical regression analyses indicated that workload was associated with psychological wellbeing, distress and depression at the one-year follow-up. Specifically, high workload at Time 1 was associated with psychological distress and depression at Time 2, and low workload was associated with psychological wellbeing at Time 2. Further, there was a significant relationship between perceived informational justice at Time 1 and psychological wellbeing at Time 2. No significant interaction effects were demonstrated for the job characteristics or organizational justice onto psychological health status. That is, longitudinally, workload directly influences both positive and negative mental health, and informational justice is related to psychological wellbeing. The implications for the demand-control-support model are discussed. The injustice-as-stressor argument was generally not supported.

The relationship betwen NaCl concentration and taste perception of saltiness in bread

Background – Sodium (Na+ ) is present in food in the form of sodium chloride (NaCl). There is strong evidence that high dietary Na+ intakes increase the risk of developing various adverse health conditions. Many international organisations encourage Na+ reduction in both the diet and the food supply. One of the major dietary sources of NaCl is bread, where NaCl has the essential function of imparting flavour. At present, no literature has been published examining taste interactions that may play a role in limiting the maximum saltiness perception in bread.
Objective – To determine the extent the physical structure of bread inhibits salty taste perception. Additionally, to determine whether common commercial bread additives suppress saltiness of bread.
Design – Subjects (n=14, 12 females) tasted and rated samples with varying NaCl concentrations in water (0 – 1724 mg NaCl/100 g) and bread (125 – 1550 mg NaCl/100 g) using the general Labelled Magnitude Scale. Psychophysical curves plotting NaCl concentration against NaCl intensity were constructed for water and bread. Breads of fixed NaCl concentration (1125 mg NaCl/100 g) and various common additives (sucrose, soya flour, canola oil, gluten) were also rated to assess perceived saltiness.
Outcomes – There was a significant difference between Na+ psychophysical curves in water and bread (P<0.05) with the bread matrix suppressing maximum possible saltiness by 25% to 70%. Suppression of saltiness was observed after the addition of sucrose (55% decrease) or soya flour (60% decrease) during bread production compared to prototypical bread (both P<0.05).
Conclusions – The physical structure of bread and some common additives have a major influence on perceptual saltiness of bread. The removal of additives that suppress saltiness combined with strategies to modify the texture of bread could lead to significant reduction in dietary Na+, whilst maintaining optimal salty taste.

Investor perception of the business case for sustainable office buildings : evidence from New Zealand

Over recent years the global market for sustainable commercial property has been growing in importance, with rapid growth occurring overseas that has led to substantial changes in the property markets. The New Zealand property industry has been recently introduced to the concept of sustainability, and although still at an early stage is already noticing the accelerating uptake of sustainability in the industry. Although certain measures have been taken by the New Zealand Green Building Council and government mandates, there remains still a common assumption that there is considerable hesitation and skeptism in the market from both an investor’s and a building owner’s perspective.

The research presented in this paper reports on the results of an investigation into the market perception toward sustainable buildings from the investment community in New Zealand. Property developers and investors from New Zealand were surveyed about their perception of sustainable buildings in New Zealand and their actions with regards to their own commercial portfolios, as well as the impact sustainability is having upon investment decisions. This paper presents the results of research conducted into the relationship between the elements of sustainability and the market value of an office building. The paper provides an insight into the rapidly evolving area of sustainability and office buildings, with the emphasis placed on the valuation process that seeks to assess a hypothetical purchaser’s perspective of this relationship.

Health implications of body size perception and weight tolerance in older adults

Obesity is a well-recognized risk factor for Type II diabetes and cardiovascular disease. In this study a high percentage of older adults were either overweight or obese. The aims were to assess older adults' tolerance for excess weight, and to compare self-perceptions of an acceptable weight with national guidelines. Participants were 76 males and females aged between 65 and 97 years. Results indicated that 60 per cent accurately identified their own body size. Further, participants were more tolerant of excess weight in males compared to females, regardless of age. It was concluded that this cohort remains vulnerable to weight-related illnesses.

Postural neck pain : an investigation of habitual sitting posture, perception of 'good' posture and cervicothoracic kinaesthesia

Impairments of cervico-cephalic kinaesthesia and habitual forward head posture have been considered important in the aetiology of postural neck pain, yet these factors have not been specifically examined in a homogeneous clinical population. The objective of this study was to compare the habitual sitting posture (HSP), perception of good posture and postural repositioning error (PRE) of the cervico-thoracic (CT) spine in individuals with postural neck pain, with a matched group of asymptomatic subjects. Twenty-one subjects with postural neck pain and 22 asymptomatic control subjects were recruited into the study. An optical motion analysis system was used to measure the HSP and perceived ‘good’ sitting posture. PRE was measured over six trials where the subject attempted to replicate their self-selected ‘good’ posture. There was no difference between the groups in the HSP but significant differences were identified in the perception of ‘good’ posture. Posture repositioning error was higher for the head posture variables than for CT and shoulder girdle variables in both groups. However, there was no significant difference in posture repositioning error between groups for any of the posture measures. The findings suggest that individuals with postural neck pain may have a different perception of ‘good’ posture, but no significant difference in HSP or kinaesthetic sensibility compared with matched asymptomatic subjects.
