Perceptions of Place - evaluating experiential qualities of streetscapes

Working with a small set of 60 images from a collection of over 1000 digital photographs, the following paper presents ongoing research into the experiential qualities of street scapes. This paper examines the initial results of a survey of 75 voluntary based perceptive studies and focusses on a sample cohort of 30 participants (20 cognate and 10 non-cognate respondents) who were asked to evaluate a streetscape experience based on favourable and unfavourable perceptive qualities. Using a spatial sequencing process, akin to the 'Serial Vision' methodology of Gordon Cullen, respondents were asked to rate a section of urban fabric based on favourable (hot or warm) and unfavourable (cold or cool) traits and to digitally capture these images. The study yields results which highlight the importance of the quality and effect of green attributes within the overall street scape experience. The implications for urban design practice (streetscape greening), are briefly explored.

Value-added role of internal audit : an Ethiopian case study

Purpose – The purpose of this paper is to draw inferences – from the results of an Ethiopian public sector corporation (for-profit) case study – on how the attributes of a value-adding internal audit department would vary among organisations.

Design/methodology/approach – The case study strategy is employed. The internal audit function of a public sector corporation was examined using an analytical framework derived from the literature. Research evidence was gathered distributing questionnaires to managers and internal auditors, conducting a semi-structured interview with the internal audit department manager, and reviewing documents.

Findings – The results highlight that traditional/compliance audit is dominant in the organisation studied as contrasted with value-added auditing. The paper concludes that goals and strategies pursued and the level of risk faced by organisations to which internal audit provides service, appear to shape the attributes of a value-adding internal audit department. The study also demonstrates that the quality of strategic planning for, and marketing of, internal audit would influence the extent to which an appropriate value-added profile is attained in a particular context.

Research limitations/implications – Since a single unit of analysis is examined, universal generalisability of the findings cannot be claimed. Also, the research design assumed that the unit of analysis investigated falls within the scope of internal audit departments considered in the literature that served as a basis to develop the analytical framework and data collection instruments.

Originality/value – The paper is expected to inspire conclusive follow-on research on the role of internal audit in Ethiopia, or other countries with similar settings.

Education and work in service of the nation: Canadian and Australian girls' fiction, 1908-1921

This chapter compares early twentieth-century Australian novels by Ethel Turner, Mary Grant Bruce, and Lilian Turner to Canadian novels by Nellie McClung and L.M. Montgomery to demonstrate important differences in attitudes towards education and work. Girls’ fiction in these white settler colonies has many similarities, containing strong ideals related to domesticity, education, employment, and femininity. In the Canadian fiction, attitudes towards women’s higher education and employement are generally much more positive. Although both Australian and Canadian girls’ fiction typically conclude with marriage, Montgomery’s Anne of Green Gables and Nellie McClung’s Pearlie Watson are offered the opportunity to pursue higher education and use this education to teach others. In contrast, Lilian Turner’s Paradise and the Perrys, Ethel Turner’s Fair Ines, and Mary Grant Bruce’s ’Possum emphasise the importance of domesticity while also showing how girls sought to earn income without leaving home. Through our comparison of these Canadian and Australian novels, all published between 1908 and 1921, we demonstrate how the different feminine ideals embodied through these heroines are inevitably intertwined with the needs of the nation

Effect of changes to the school food environment on eating behaviours and/or body weight in children: a systematic review

Previous school obesity-prevention reviews have included multi-component interventions. Here, we aimed to review the evidence for the effect of isolated food environment interventions on both eating behaviours (including food purchasing) and/or body weight. Five electronic databases were searched (last updated 30 November 2013). Of the 1,002 unique papers identified, 55 reported on school food environment changes, based on a review of titles and abstracts. Thirty-seven further papers were excluded, for not meeting the inclusion criteria. The final selection consisted of 18 papers (14 United States, 4 United Kingdom). Two studies had a body mass index (BMI) outcome, 14 assessed purchasing or eating behaviours and two studies assessed both weight and behaviour. Seventeen of 18 papers reported a positive outcome on either BMI (or change in BMI) or the healthfulness of food sold or consumed. Two studies were rated as strong quality and 11 as weak. Only three studies included a control group. A school environment supportive of healthy eating is essential to combat heavy marketing of unhealthy food. Modification of the school food environment (including high-level policy changes at state or national level) can have a positive impact on eating behaviours. A need exists, however, for further high-quality studies.

Optimal design of traffic signal controller using neural networks and fuzzy logic systems

This paper aims at optimally adjusting a set of green times for traffic lights in a single intersection with the purpose of minimizing travel delay time and traffic congestion. Neural network (NN) and fuzzy logic system (FLS) are two methods applied to develop intelligent traffic timing controller. For this purpose, an intersection is considered and simulated as an intelligent agent that learns how to set green times in each cycle based on the traffic information. The training approach and data for both these learning methods are similar. Both methods use genetic algorithm to tune their parameters during learning. Finally, The performance of the two intelligent learning methods is compared with the performance of simple fixed-time method. Simulation results indicate that both intelligent methods significantly reduce the total delay in the network compared to the fixed-time method.

Epigallocatechin-3-gallate induces the apoptosis of hepatocellular carcinoma LM6 cells but not non-cancerous liver cells

Epigallocatechin-3-gallate (EGCG) is a constituent of green tea and has been associated with anticancer activity. In the present study, the inhibitory effect of EGCG on human hepatocellular cancer cells was examined by cell viability assay, in vitro apoptosis assay and cell cycle analysis. In addition, gene expression was measured to elucidate the molecular mechanisms of action of EGCG by mitochondrial membrane potential (MMP) determination and western blot analysis. We demonstrated that EGCG induced apoptosis, decreased mitochondrial membrane potential and promoted G0/G1 phase cell cycle arrest of HCCLM6 cells but not that of non-cancerous liver cells (HL-7702). The EGCG-induced apoptosis of HCCLM6 cells was associated with a significant decrease in Bcl-2 and NF-κB expression. In addition, the expression of Bax, p53, caspase-9 and caspase-3 increased, and cytochrome c was released. These results suggest that EGCG inhibits the progression of cancer through cytocidal activity and that it is a potential therapeutic compound for hepatocellular carcinoma (HCC).

BMI and healthcare cost impact of eliminating tax subsidy for advertising unhealthy food to youth

INTRODUCTION: Food and beverage TV advertising contributes to childhood obesity. The current tax treatment of advertising as an ordinary business expense in the U.S. subsidizes marketing of nutritionally poor foods and beverages to children. This study models the effect of a national intervention that eliminates the tax subsidy of advertising nutritionally poor foods and beverages on TV to children aged 2-19 years. METHODS: We adapted and modified the Assessing Cost Effectiveness framework and methods to create the Childhood Obesity Intervention Cost Effectiveness Study model to simulate the impact of the intervention over the 2015-2025 period for the U.S. population, including short-term effects on BMI and 10-year healthcare expenditures. We simulated uncertainty intervals (UIs) using probabilistic sensitivity analysis and discounted outcomes at 3% annually. Data were analyzed in 2014. RESULTS: We estimated the intervention would reduce an aggregate 2.13 million (95% UI=0.83 million, 3.52 million) BMI units in the population and would cost $1.16 per BMI unit reduced (95% UI=$0.51, $2.63). From 2015 to 2025, the intervention would result in $352 million (95% UI=$138 million, $581 million) in healthcare cost savings and gain 4,538 (95% UI=1,752, 7,489) quality-adjusted life-years. CONCLUSIONS: Eliminating the tax subsidy of TV advertising costs for nutritionally poor foods and beverages advertised to children and adolescents would likely be a cost-saving strategy to reduce childhood obesity and related healthcare expenditures.

Child and adolescent obesity: part of a bigger picture

The prevalence of childhood overweight and obesity has risen substantially worldwide in less than one generation. In the USA, the average weight of a child has risen by more than 5 kg within three decades, to a point where a third of the country's children are overweight or obese. Some low-income and middle-income countries have reported similar or more rapid rises in child obesity, despite continuing high levels of undernutrition. Nutrition policies to tackle child obesity need to promote healthy growth and household nutrition security and protect children from inducements to be inactive or to overconsume foods of poor nutritional quality. The promotion of energy-rich and nutrient-poor products will encourage rapid weight gain in early childhood and exacerbate risk factors for chronic disease in all children, especially those showing poor linear growth. Whereas much public health effort has been expended to restrict the adverse marketing of breastmilk substitutes, similar effort now needs to be expanded and strengthened to protect older children from increasingly sophisticated marketing of sedentary activities and energy-dense, nutrient-poor foods and beverages. To meet this challenge, the governance of food supply and food markets should be improved and commercial activities subordinated to protect and promote children's health.

Children's implicit recall of junk food, alcohol and gambling sponsorship in Australian sport

BACKGROUND: In Australia, sport is saturated by the promotion of junk food, alcohol and gambling products. This is particularly evident on player jerseys. The effect of this advertising on children, who are exposed to these messages while watching sport, has not been thoroughly investigated. The aim of this research study was to investigate: (1) the extent to which children implicitly recalled shirt sponsors with the correct sporting team; (2) whether children associated some types of sponsors with certain sporting codes more than others; and (3) whether age of the children influenced the correct recall of sponsoring brands and teams. METHOD: This experimental study conducted in New South Wales, Australia used projective techniques to measure the implicit recall of team sponsorship relationships of 85 children aged 5-12 years. Participants were asked to arrange two sets of magnets - one which contained sporting teams and one which contained brand logos - in the manner deemed most appropriate by them. Children were not given any prompts relating to sporting sponsorship relationships. RESULTS: Three quarters (77 %) of the children were able to identify at least one correct shirt sponsor. Children associated alcohol and gambling brands more highly with the more popular sporting code, the National Rugby League compared to the Australian Football League sporting code. Results showed that age had an effect on number of shirt sponsors correctly recalled with 9-12 year olds being significantly more likely than 5-8 year olds to correctly identify team sponsors. CONCLUSIONS: Given children's ability to implicitly recall shirt sponsors in a sporting context, Australian sporting codes should examine their current sponsorship relationships to reduce the number of unhealthy commodity shirt sponsors. While there is some regulation that protects children from the marketing of unhealthy commodity products, these findings suggest that children are still exposed to and recall these sponsorship relationships. Results suggest that the promotion of unhealthy commodity products during sporting matches is contributing to increased awareness amongst children of unhealthy commodity brands. Further investigation is required to examine the extent and impact of marketing initiatives during televised sporting matches on children.

Design of an optimal ANFIS traffic signal controller by using cuckoo search for an isolated intersection

An optimal design of Adaptive Neuro-Fuzzy Inference System (ANFIS) traffic signal controller is presented in this paper. The proposed controller aims to adjust a set of green times for traffic lights in a single intersection with the purpose of minimizing travel delay time and traffic congestion. The ANFIS controller is trained, to learned how to set green times for each traffic phase. This intelligent controller uses the Cuckoo Search (CS) algorithm to tune its parameters during the learning pried. Evaluating the performance of the proposed controller in comparison with the performance of a FLS controller (FLC) with predefined rules and membership functions, and also three fixed-Time controllers, illustrates the better performance of the optimal ANFIS controller against the other benchmark controllers.

O canal de distribuição para produtos cosméticos em Porto Alegre : uma análise com foco nos salões de beleza

As empresas estão participando de um mercado cada vez mais competitivo. Esta disputa acirrada das empresas pelos clientes tem propiciado canais alternativos de distribuição dos produtos aos diferentes segmentos de mercado. Os canais de distribuição estão adquirindo uma importância cada vez maior aos olhos dos fabricantes e dos clientes, principalmente na questão de serviços. De acordo com Ballou (2001, p.44), “o serviço ao cliente, inclui disponibilidade de estoques, rapidez na entrega, rapidez e acuracidade no preenchimento de pedidos”. A esses serviços pode ser somada uma gama variada de outros serviços a serem prestados pelos participantes do canal de distribuição ou pelos fabricantes. A empresa Ravel Produtos Cosméticos e Dermatológicos será a principal usuária dos resultados obtidos com este estudo, pois é fabricante de produtos cosméticos e tem seu foco de atuação principal na cidade de Porto Alegre. O objetivo deste trabalho foi analisar o canal de distribuição para produtos cosméticos destinados a consumidores de alta renda no mercado de Porto Alegre, procurando identificar os aspectos de serviços demandados, produtos utilizados e mix de produtos comercializados pelo canal de distribuição: salões de beleza. O estudo foi realizado através de pesquisa qualitativa, com entrevistas individuais junto aos proprietários dos salões, ou junto às pessoas que decidem o mix de produtos a ser utilizado ou comercializado pelos salões. O mix de produtos comercializados pelos salões de beleza em Porto Alegre conforme a pesquisa realizada, é o seguinte: xampus, cremes, máscaras, hidratantes, fluidos e géis.

The implications of embodiment and Putty-Clay to economic development

In this paper we construct and analyze a growth model with the following three ingredients. (i) Technological progress is embodied. (ii) The production function of a firm is such that the firm makes both technology upgrade as well as capital and labor decisions. (iii) The firm’s production technology is putty-clay. We assume that there are disincentives to the accumulation of capital, resulting in a divergence between the social and the private cost of investment. We solve a single firm’s problem in this environment. Then we determine general equilibrium prices of capital goods of different vintages. Using these prices we aggregate firms’ decisions and construct the theoretical analogues of National Income statistics. This generates a relationship between disincentives and per capita incomes. We analyze this relationship and show the quantitative and qualitative roles of embodiment and putty-clay. We also show how the model is taken to data, quantified and used to determine to what extent income gaps across countries can be attributed to disincentives.

Productivity of nations: a stochastic frontier approach to TFP decomposition

This Paper Tackles the Problem of Aggregate Tfp Measurement Using Stochastic Frontier Analysis (Sfa). Data From Penn World Table 6.1 are Used to Estimate a World Production Frontier For a Sample of 75 Countries Over a Long Period (1950-2000) Taking Advantage of the Model Offered By Battese and Coelli (1992). We Also Apply the Decomposition of Tfp Suggested By Bauer (1990) and Kumbhakar (2000) to a Smaller Sample of 36 Countries Over the Period 1970-2000 in Order to Evaluate the Effects of Changes in Efficiency (Technical and Allocative), Scale Effects and Technical Change. This Allows Us to Analyze the Role of Productivity and Its Components in Economic Growth of Developed and Developing Nations in Addition to the Importance of Factor Accumulation. Although not Much Explored in the Study of Economic Growth, Frontier Techniques Seem to Be of Particular Interest For That Purpose Since the Separation of Efficiency Effects and Technical Change Has a Direct Interpretation in Terms of the Catch-Up Debate. The Estimated Technical Efficiency Scores Reveal the Efficiency of Nations in the Production of Non Tradable Goods Since the Gdp Series Used is Ppp-Adjusted. We Also Provide a Second Set of Efficiency Scores Corrected in Order to Reveal Efficiency in the Production of Tradable Goods and Rank Them. When Compared to the Rankings of Productivity Indexes Offered By Non-Frontier Studies of Hall and Jones (1996) and Islam (1995) Our Ranking Shows a Somewhat More Intuitive Order of Countries. Rankings of the Technical Change and Scale Effects Components of Tfp Change are Also Very Intuitive. We Also Show That Productivity is Responsible For Virtually All the Differences of Performance Between Developed and Developing Countries in Terms of Rates of Growth of Income Per Worker. More Important, We Find That Changes in Allocative Efficiency Play a Crucial Role in Explaining Differences in the Productivity of Developed and Developing Nations, Even Larger Than the One Played By the Technology Gap

Evolução do conforto doméstico no estado de S. Paulo, 1980-2002: análise quantitativa

É nítida e rápida a popularização da maioria dos bens duráveis de consumo no Estado de São Paulo, nos últimos vinte anos. Colaboram para isso a universalização da oferta domiciliar de eletricidade, água encanada, esgotos, e a tendência ao barateamento dos bens. Entre outros efeitos, tal popularização deteriora a eficácia das escalas de classificação sócio- econômica baseadas na posse de itens de conforto doméstico, suscitando freqüentes revisões e discórdias no interior da comunidade de marketing. Este estudo sistematiza estatísticas sobre situação domiciliar e posse de itens de conforto doméstico no Estado de S. Paulo, e mostra como isso afeta o consumo material e cultural. Finalmente, aponta que é chegada a hora de se usar mais e melhor variáveis como educação, profissão, qualidade do domicílio, tal como se faz em países desenvolvidos, para o entendimento mais pleno das mudanças que implantam no Brasil a moderna sociedade de consumo.

Uma investigação empírico-exploratória acerca da rentabilidade dos clientes freqüentes e esporádicos no varejo eletrônico brasileiro

o presente estudo de caso investiga, empiricamente, a rentabilidade associada aos consumidores do varejo eletrônico de bens duráveis no Brasil. Para tal, o arcabouço teórico baseia-se em teorias rivais, notadamente as expostas na literatura tradicional do Marketing de Relacionamento - que discute os beneficios da retenção de clientes - e nas recentes publicações que questionam tal abordagem - argumentando que os consumidores esporádicos podem se mostrar mais valiosos que os freqüentes. Nas duas empresas investigadas, os clientes esporádicos demonstram-se mais rentáveis que os freqüentes. Entretanto, a análise exploratória dos dados qualitativos demonstra que ambas utilizam abordagens transacionais para interagir com os consumidores. O cruzamento das evidências quali-quantitativas sugere que o declínio do valor dos clientes freqüentes está associado a práticas gerenciais que não se encontram em conformidade com a literatura convencional de marketing. Por conseguinte, as evidências quantitativas parecem não representar anomalias perante a teoria vigente, segundo a qual os beneficios inerentes à retenção de consumidores fazem sentido apenas para as empresas que estiverem orientadas a clientes e puderem interagir de forma relacional com os mesmos. O estudo possibilita supor que o valor dos clientes está associado à forma como as empresas se relacionam com o mercado. A adoção de práticas transacionais, a baixa diferenciação e a competição baseada em descontos parece potencializar a sensibilidade ao preço por parte dos consumidores, principalmente daqueles mais freqüentemente.
