"Roll Up and Spend Your Last Dime". The Merry-go-round of Children`s Extra-curricular Activities in Modern Society.

"Step up and play" begins the famous hit song 'Penny Arcade'. And so it
was for thousands of Australian families, as their eldest child began school
this year, and the associated endless merry-go-round of extra-curricular
activities also began. But how many of those families realise that the song ends "Roll up and spend your last dime!"? While the perceived benefits of
children's involvement in extracurricular activities are many and are widely accepted, there are also costs, not only in terms of money but also in terms
of time. Evidence from a study conducted in Melbourne highlights the fact that, for many families such as those on low incomes and those headed by a single parent, both the time and the money costs may be prohibitive. This article highlights parents' perceptions of the benefits·and costs of children's extra-curricular activities, and explores the implications of changing family and household structures for families' capacity to sustain such activities.

Extra relationship involvement among women: are they different from men?

Factors related to three types ofExtra Relationship Involvement (ERI) in women were explored: emotional ERI, sexual ERJ, and II combination ofsexual and emotional ERIs . A model, based on a decision-making model of male ERI and the additional variable of commitment, was evaluated. The research involved two studies with female participants (N = 112, N = 44) who had been involved in heterosexual relationships of at least 6-month duration. The major finding was that women engage in emotional and combined ERIs but rarely enter into solely sexual ERIs. It was demonstrated that social norms, planning, relationship satisfaction, and commitment were influential in predicting emotional and combined ERI intentions. Past ERI behavior was a strong predictor offuture emotional and combined ERI behavior, but planning also added to the prediction of combined ERI behavior. Women who had engaged in emotional ERIs and combined ERIs indicated romantic affect as the main reasonfor their ERI behavior. Overall, it was demonstrated that women's intentions to engage in ERI were related to cognitive processes and relationship variables, and that ERI behavior, although generally habitual, was also predicted by cognitive processes.

Consumption of 'extra' foods (energy-dense, nutrient poor) among children aged 16-24 months from western Sydney, Australia

Objective: This study evaluates the contribution of energy-dense, nutrient-poor ‘extra’ foods to the diets of 16–24-month-old children from western Sydney, Australia.

Design:   An analysis of cross-sectional data collected on participants in the Childhood Asthma Prevention Study (CAPS), a randomised trial investigating the primary prevention of asthma from birth to 5 years. We collected 3-day weighed food records, calculated nutrient intakes, classified recorded foods into major food groups, and further classified foods as either ‘core’ or ‘extras’ according to the Australian Guide to Healthy Eating.

Setting:  Pregnant women, whose unborn child was at risk of developing asthma because of a family history, were recruited from all six hospitals in western Sydney, Australia. Data for this study were collected in clinic visits and at participants’ homes at the 18-month assessment.

Participants: Four hundred and twenty-nine children participating in the CAPS study; 80% of the total cohort.

Results:  The mean consumption of ‘extra’ foods was xs223C150 g day− 1 and contributed 25–30% of the total energy, fat, carbohydrate and sodium to the diets of the study children. ‘Extra’ foods also contributed around 20% of fibre, 10% of protein and zinc, and about 5% of calcium. Children in the highest quintile of ‘extra’ foods intake had a slightly higher but not significantly different intake of energy from those in the lowest quintile. However, significant differences were evident for the percentage of energy provided by carbohydrate and sugars (higher) and protein and saturated fat (lower). The intake of most micronutrients was also significantly lower among children in the highest quintile of consumption. The intake of ‘extra’ foods was inversely associated with the intake of core foods.

Conclusions:  The high percentage of energy contributed by ‘extra’ foods and their negative association with nutrient density emphasise the need for dietary guidance for parents of children aged 1–2 years. These preliminary data on commonly consumed ‘extra’ foods and portion sizes may inform age-specific dietary assessment methods.

Using organizational justice to predict in-role and extra-role performance works in different ways for men relative to women

Distributive, procedural, interpersonal and informational justices were included in this study of gender differences in in-role and extra-role behavior. Distributive justice predicted performance, organizational commitment and OCB for men but only performance and job satisfaction for women. Procedural justice predicted job satisfaction for men and did not predict any outcomes for women. Informational justice predicted job satisfaction for both male and female respondents. Informational justice predicted female but not male organizational commitment and in-role performance. Interpersonal justice predicted male but not female organizational citizenship behavior. The study demonstrates important distinctions between the four organizational justice types and how men and women respond differently to those distinctions. The differences in the drivers of in-role performance between men and women may also have practical implications for managers. For example, distributive justice was a direct in-role performance driver for both genders, but informational justice provides an incremental direct effect for women.

Predicting in-role and extra-role performance by gender

Men and women are said to perceive justice differently, with women proposed to be more concerned with relational issues and men focused more on material issues. In this study, the potential for differential effects of justice on performance by gender was analyzed across the four contemporary types of justice. Respondents were 265 male and 113 female occupationally diverse employees in a single organization. The results show significant differences in how men and women respond to the four justice types with only one - informational justice - acting similarly by gender. Women were more interested in maintaining social harmony than men. The results appear to strongly support the use of the justice judgment model over the group-value model as a means of explaining the gender differences. Implications for management include the importance of informational justice both generally and within the performance appraisal process

Sensory characterization of the irritant properties of oleocanthal, a natural anti-inflammatory agent in extra virgin olive oils

Oleocanthal is an olive oil phenolic possessing anti-inflammatory activity. Anecdotal evidence suggests that oleocanthal elicits a stinging sensation felt only at the back of the throat (oropharynx). Due to this compound possessing potentially health-benefiting properties, investigation into the sensory aspects of oleocanthal is warranted to aid in future research. The important link between the perceptual aspects of oleocanthal and health benefits is the notion that variation in sensitivity to oleocanthal irritation may relate to potential differences in sensitivity to the pharmacologic action of this compound. The current study assessed the unique irritant attributes of oleocanthal including its location of irritation, temporal profile, and individual differences in the perceived irritation. We show that the irritation elicited by oleocanthal was localized to the oropharynx (P < 0.001) with little or no irritation in the anterior oral cavity. Peak irritation was perceived 15 s postexposure and lasted over 180 s. Oleocanthal irritation was more variable among individuals compared with the irritation elicited by CO₂ and the sweetness of sucrose. There was no correlation between intensity ratings of oleocanthal and CO₂ and oleocanthal and sucrose (r = –0.15, n = 50, P = 0.92 and r = 0.17, n = 84, P = 0.12, respectively), suggesting that independent mechanisms underlie the irritation of CO₂ and oleocanthal. The unusual spatial localization and independence of acid (CO₂) sensations suggest that distinct nociceptors for oleocanthal are located in the oropharyngeal region of the oral cavity.

Oleocanthal, a natural anti-Inflammatory compound in extra virgin olive oil

Recent research on the olive oil phenolic, oleo canthal has led to speculation that it may confer some of the health benefits associated with a traditional Mediterranean diet. Oleocanthal produces a peppery, stinging sensation at the back of the throat similar to that of the non-steroidal anti-inflammatory drug (NSAID), ibuprofen. This led to the hypothesis that the perceptual similarity between oleocanthal and ibuprofen may indicate similar pharmacological properties. Subsequent studies have proved the hypothesis and oleocanthal was shown not only to inhibit inflammation in the same way as ibuprofen does, but it was found to be substantially more potent than this NSAID. It is important to note that inflammation has been demonstrated to playa significant role in the development of a number of chronic diseases, such as cardiovascular disease (CVD) and certain types of cancers. Therefore, as a result of dietary feeding with olive oil as a part of the traditional Mediterranean diet, a reduction in inflammation produced by oleocanthal is speculated to be the potential mechanism that is partially responsible for the health benefits associated with this dietary pattern. This review summarizes the current knowledge on oleocanthal, in tenns of its physiological and sensory properties, as well as a discussion on the factors that have the ability to affect oleocanthal concentrations in extra virgin olive oils (EVOOs).

Antimicrobial, antioxidant and anti-inflammatory phenolic activities in extra virgin olive oil

The Mediterranean diet is associated with a lower incidence of chronic degenerative diseases and higher life expectancy. These health benefits have been partially attributed to the dietary consumption of extra virgin olive oil (EVOO) by Mediterranean populations, and more specifically the phenolic compounds naturally present in EVOO. Studies involving humans and animals (in vivo and in vitro) have demonstrated that olive oil phenolic compounds have potentially beneficial biological effects resulting from their antimicrobial, antioxidant and anti-inflammatory activities. This paper summarizes current knowledge on the biological activities of specific olive oil phenolic compounds together with information on their concentration in EVOO, bioavailability and stability over time.

The influence of job, team and organizational level resources on employee well-being, engagement, commitment and extra-role performance : test of a model

Purpose – Worker well-being continues to be fundamental to the study of work and a primary consideration for how organizations can achieve competitive advantage and sustainable and ethical work practices (Cartwright and Holmes; Harter, Schmidt and Keyes; Wright and Cropanzano). The science and practice of employee engagement, a key indicator of employee well-being, continues to evolve with ongoing incremental refinements to existing models and measures. This study aims to elaborate the Job Demands-Resources model of work engagement (Bakker and Demerouti) by examining how organizational, team and job level factors interrelate to influence engagement and well-being and downstream outcome variables such as affective commitment and extra-role behaviour.

Design/methodology/approach – Structural equations modelling of survey data obtained from 3,437 employees of a large multi-national mining company was used to test the important direct and indirect influence of organizational focused resources (a culture of fairness and support), team focused resources (team climate) and job level resources (career development, autonomy, supervisor support, and role clarity) on employee well-being, engagement, extra-role behaviour and organizational commitment.

Findings – The fit of the proposed measurement and structural models met criterion levels and the structural model accounted for sizable proportions of the variance in engagement/wellbeing (66 percent), extra-role-behaviour (52 percent) and commitment (69 percent).

Research limitations/implications – Study limitations (e.g. cross-sectional research design) and future opportunities are outlined.

Originality/value – The study demonstrates important extensions to the Job Demands-Resources model and provides researchers and practitioners with a simple but powerful motivational framework, a suite of measures, and a map of their inter-relationships which can be used to help understand, develop and manage employee well-being and engagement and their outcomes.
