Characteristics and factors influencing fast food intake of young adult consumers in Johannesburg, South Africa
MK Van Zyl, NP Steyn, ML Marais
South African Journal of Clinical Nutrition , 2010,
Abstract: Objectives: To determine fast food consumption patterns, socio-economic characteristics and other factors that influence the fast food intake of young adults from different socio-economic areas in Johannesburg, South Africa. Methods: A descriptive, cross-sectional study was undertaken, using an interviewer-administered, validated questionnaire to elicit the characteristics of the study population (adults aged from 19 to 30 years), their reasons for and frequency of fast food consumption, their specific fast food choices, and their attitudes towards health. Results: The study population (n = 341) consisted primarily of young working adults (n = 242) with at least a secondary education. Almost half (42%, n = 102) of the employed participants earned less than R5 000 per month, but spent more than R200 on fast food per month. Twenty-one per cent of all participants had fast food at least once a week, while 27.6% had it two to three times a week. Socio-economic group (SEG) and gender were significantly related to fast food intake (p < 0.01), with a larger proportion of participants (65%, n = 76) in the lower socio-economic group (LSEG) showing more frequent use. Males consumed fast food more frequently than females. The most popular fast foods consumed were burgers (69.5%), pizza (56.6%) and fried chicken (38.4%). Soft drinks were the most popular beverage consumed (56%). The main reasons for choosing fast food were time limitations (58.9%), convenience (58.2%) and taste (52.5%). The majority of the participants were concerned about their health (93.3%) and indicated a fear of becoming overweight (44.3%). Seventy-eight per cent of all the participants would have chosen a healthier option if it had been available on the menu. Television was reported to be the most effective medium influencing their food choices. Conclusion: Fast food intake appears to be very common in this group of young South African adults. Various factors that influence fast food intake were identified that provide health educators and policy makers with useful information for health promotion.
Who is the nutrition workforce in the Western Cape?
H Goeiman, D Labadarios, NP Steyn
South African Journal of Clinical Nutrition , 2011,
Abstract: Objectives: The aim of the present study was to determine the current nutrition staffing profile of the Integrated Nutrition Programme (INP) in Department of Health in the Western Cape, and establish whether it is adequate to meet the objectives of the INP. Method: Self-administered questionnaires compiled in English were used as the main data collection instrument for nutrition staff in districts and at hospitals (n = 647). Eight individual questionnaires, one per staff category, were developed and utilised in the study. Results: Foodservice workers were the largest group of nutrition personnel (n = 509; 79%), followed by dietitians (n = 64; 10%), managers (n = 31; 5%), auxiliary workers (n = 28; 4%), and administrative workers (n = 15; 2%). Sixty-two per cent of the nutrition workforce was located in urban areas and 38% in rural districts. Hospital and district dietitians experienced common problems, as well as specific differences. Regarding problems, both categories referred to limited resources, inadequate number of available posts, and lack of acknowledgement and support from administrative and supply chain management. District dietitians were also hampered by lack of space for consultations, poor referrals from doctors, insufficient posts for nutrition advisers, and difficulty in communicating with Xhosa-speaking patients. Hospital dietitians were hampered by insufficient interaction with district dietitians and lack of dietitians for specialised units. They also mentioned that poor salaries were affecting morale. Conclusion: Recommendations such as additional posts for dietitians, improved conditions of service and salaries, increased advocacy for nutrition, and a number of human resources recommendations were made, and should be considered if the INP objectives are to be met.
Nutrition interventions in the workplace: Evidence of best practice
NP Steyn, W Parker, EV Lambert, Z Mchiza
South African Journal of Clinical Nutrition , 2009,
Abstract: Aim: The aim of this desktop study was to review all workplace interventions having a nutrition component, published in peer-reviewed literature between 1995 and 2006 by WHO, and to document activities that were successful, as well as possible barriers to their success. Methodology: A systematic review of workplace studies revealed 41 interventions, of which 30 complied with the predetermined search criteria. The following outcome measures were considered in the evaluation of the interventions: (i) changes in nutritional knowledge, attitudes, self-efficacy, intentions and stage of change; (ii) changes in dietary behaviours; (iii) changes in clinical/physical markers, such as: body weight or body-mass index (BMI), blood pressure (BP) or serum cholesterol concentrations; and (iv) process and/or policy outcomes. Results: A large number of diverse workplace interventions were successful in changing outcomes positively in the interventions evaluated. The following were key success factors: i) there was a nutrition and physical activity component; ii) dietitians were involved in nutrition education; iii) changes occurred in the cafeteria/canteen, which increased the availability of healthy food options and advertised them accordingly; iv) tailored feedback on diet (and clinical values) was given to subjects; v) employees were involved in planning and managing programmes; vi) the reduced prices (of healthy food items) in vending machines encouraged employees to buy healthier options; and vii) the stages of change theory was most commonly associated with best practice outcomes. Conclusions: Numerous workplace interventions have shown significant improvements in employees’ health and behaviours. However, it is necessary to plan intervention programmes based on the existing evidence of best practice.
A review of school nutrition interventions globally as an evidence base for the development of the HealthKick programme in the Western Cape, South Africa
NP Steyn, EV Lambert, W Parker, Z Mchiza, A De Villiers
South African Journal of Clinical Nutrition , 2009,
Abstract: Aim: The aim of this study was to review all school interventions having a nutrition component, published in peer-reviewed literature between 1995 and 2006, and to document activities that were successful as well as those that were possible barriers in order to develop a best practice school intervention for the Western Cape Province, South Africa. Methodology: A systematic review of school studies revealed 85 interventions that complied with the predetermined search criteria. The following outcome measures were considered in the evaluation of the interventions: (i) changes in nutritional knowledge, attitudes and selfefficacy and stage of change; (ii) changes in dietary behaviours; (iii) changes in clinical/physical markers such as body weight or body mass index, blood pressure or serum cholesterol concentrations; and (iv) process and/or policy outcomes. Results: Key success factors of school-based interventions appeared to be the following: A nutrition-based curriculum offered at school by trained teachers generally improved behavioural outcomes. A physical activity programme and parental component were associated with most of the best practice clinical and behavioural outcomes. Furthermore, all best practice studies were grounded on a firm theory of behaviour, such as social cognitive, social marketing or stages of change. Most of the interventions that included a food service component had best practice behavioural outcomes. Conclusions: Numerous school-based nutrition interventions have shown significant improvements in children’s nutritional behaviours. Consequently, it is necessary to plan programmes based on existing evidence of best practice. The lessons learnt from this review have been applied in the development of the HealthKick programme initiated in schools in the Western Cape in 2007.
Rosmini’s metaphysical evidence for the existence of God
NP Swartz
Acta Theologica , 2009,
Abstract: Rosmini is of the opinion that the soul consists of both a bodily (natural) and a godly component. Both components unite in humankind. In Rosmini’s cosmology, humankind is viewed in relation to God and the world (cosmos). Cosmology cannot be comprehensively explained without linking ontology and theology, in particular. Rosmini treats human knowledge of God’s existence ontologically. According to Rosmini, we will not comprehend metaphysical or spiritual matters without understanding temporal matters (cosmology). Cosmology forms part of a higher science, namely ontology and even more so theology. Ontology treats being in its essence, in terms of which Rosmini identifies three forms, namely the ideal, the real (or actual) and the moral. The essence of being in all three forms should be similar, yet these forms differ. Although humankind is equal to the godly image, God and humankind differ in essence. Humankind shares in the ideal, the actual and the moral forms by means of the soul. Rosmini is of the opinion that the moral form, in relation to reality, forms the ideal Being. The ideal Being is infinite and essentially perfect. The infinite perfect Being can therefore not be humankind. Humankind is unable to fully comprehend the perfect Being (God). The perfect Being (God) in his totality and completeness is thus not subject to human knowledge or existence. Human reason can only know what is revealed to it through nature. According to Rosmini, we can know God in a way that surpasses human intelligence, and we can therefore not form a positive but raher a negative understanding of God.

Thomas Aquinas: On Law, Tyranny and Resistance
NP Swartz
Acta Theologica , 2010,
Abstract: Thomas Aquinas’s notion on law, tyranny and resistance served as a limitation on governmental powers. When those who bear the law command things which exceed the competence of such authority, the subject is free to obey or disobey. The function of the law culminates in two maxims: quantum ad vim coactivam legis and quantum ad vim directivam. With regard to the former, the prince is above the law (legibus solutus). It implies the principle of Salus reipublicae suprema lex, which means that the safety of the state is the supreme law. According to this principle property, liberty and life (basic individual rights) are subordinate to or even sacrificed for the supposed public good. With regard to the latter, the prince’s power should be subject to the law. The vis directiva limits the authority of the prince. This principle is in accordance with the rule of law. This notion is concomitant with the constitutional principles entrenched in the Constitution of South Africa, Act 108 of 1996. The idea of the Constitution is also bolstered by the entrenchment of the rule of law. The purpose of the rule of law is to protect basic individual rights. Hereafter the rule of law requires the prince or state to act in accordance with the law. It also means that the prince or branches of state must obey the law. If the prince or state acts without legal authority, it is acting lawlessly, which is against the notion of a constitutional democracy.

On Locally Convex Topological Vector Space Valued Paranormed Function Space Defined by Orlicz Function
NP Pahari
Nepal Journal of Science and Technology , 2013, DOI: 10.3126/njst.v14i2.10423
Abstract: The aim of this paper is to introduce and study a new class (l ∞ (X , Y , Φ, ξ, w , L ), H U ) of locally convex space Y- valued functions using Orlicz function Φ as a generalization of some of the well known sequence spaces and function spaces. Besides the investigation pertaining to the linear topological structures of the class (l ∞ (X , Y , Φ, ξ, w , L) , H U ) when topologized it with suitable natural paranorm , our primarily interest is to explore the conditions pertaining the containment relation of the class l ∞ (X , Y , Φ, ξ, w) in terms of different ξ and w so that such a class of functions is contained in or equal to another class of similar nature.

Die Afrikaans van die bybelvertaling van 19331
JC Steyn
Acta Theologica , 2009,
Abstract: The first translators of the Bible had to start their work before the standardisation of Afrikaans. This article firstly explores the difficulties encountered by the Bible translators in breaking with the language of the Statenbijbel. Secondly, it is indicated how translators were able to utilise the insights of linguists and language practitioners who were in the process of standardising the Afrikaans language. The article explores difficulties encountered by the 1933 translators regarding vocabulary, pronouns, verbs and adjectives. From the translations it is clear that by 1922 the Afrikaans is/was/wees already fell into disuse regarding verbs referring to movement and the changing of state. Not one of the translators considered the imperfect seriously; only in the 1933 translation was the historical present tense used in a stylistically satisfactory manner. The plurals of adjectives in a substantive function, and the negative imperative, were not used consistently in the 1933 translation. Article text in Afrikaans.
