DELIVER! - An educational game for teaching Earned Value Management in computing courses

Abstract: Context: To meet the growing need for education in Software Project Management, educational games have been introduced as a beneficial instructional strategy. However, there are no low-cost board games openly available to teach Earned Value Management (EVM) in computing programs. Objective: This paper presents an educational board game to reinforce and teach the application of EVM concepts in the context of undergraduate computing programs complementing expository lessons on EVM basics. Method: The game has been developed based on project management fundamentals and teaching experience in this area. So far, it has been applied in two project management courses in undergraduate computing programs at the Federal University of Santa Catarina. We evaluated motivation, user experience and the game's contribution to learning through case studies on Kirkpatrick's level one based on the perception of the students. Results: First results of the evaluation of the game indicate a perceived potential of the game to contribute to the learning of EVM concepts and their application. The results also point out a very positive effect of the game on social interaction, engagement, immersion, attention and relevance to the course objectives. Conclusion: We conclude that the game DELIVER! can contribute to the learning of the EVM on the cognitive levels of remembering, understanding and application. The illustration of the application of EVM through the game can motivate its usefulness. The game has proven to be an engaging instructional strategy, keeping students on the task and attentive. In this respect, the game offers a possibility to complement traditional instructional strategies for teaching EVM. In order to further generalize and to strengthen the validity of the results, it is important to obtain further evaluations.

Percepção da imagem corporal de crianças e adolescentes com diferentes níveis socio-econômicos na cidade de Florianópolis, Santa Catarina, Brasil

Abstract: OBJETIVOS: identificar a percepcao da imagem corporal em diferentes niveis socioeconomicos de criancas e adolescentes. METODOS: estudo transversal realizado no municipio de Florianopolis, Santa Catarina, no ano de 2006. Quatrocentos e dois escolares, com media de idade de 11,35 ± 1,98 anos, matriculados nas series finais do ensino fundamental, foram investigados. A percepcao da imagem corporal foi identificada por meio do protocolo de silhuetas de Stunkard e o nivel socioeconomico pelos criterios propostos pela Associacao Nacional de Empresas e Pesquisa (ANEP). Foram calculadas razoes de prevalencias para insatisfacao pelo excesso de peso e pela magreza. RESULTADOS: no sexo masculino, a silhueta 3 foi a mais citada nas classes alta e media e a 4 na baixa; no feminino a silhueta 2 foi a mais citada nas classes alta e baixa e a 3 na media considerando a percepcao real de sua silhueta. A silhueta 3 para o sexo masculino e a 2 para o feminino foram consideradas ideais pelo maior percentual de escolares. Os jovens da classe baixa apresentaram maiores prevalencias de insatisfacao pelo excesso de peso em relacao os da classe alta. CONCLUSOES: houve uma tendencia dos escolares das classes mais altas apresentarem insatisfacao pela magreza e das mais baixas pelo excesso de peso.

Fatores de risco cardiovascular em adolescentes de município do sul do Brasil: prevalência e associações com variáveis sociodemográficas

Abstract: OBJETIVO: Determinar a prevalencia de fatores de risco cardiovascular e analisar sua associacao com variaveis sociodemograficas em adolescentes do municipio de Tres de Maio/RS. METODOS: Estudo transversal de base escolar com amostra probabilistica, estratificada por sexo e nivel economico, composta por 660 adolescentes de 14 a 19 anos, 343 mocas (52%). Foram investigadas as prevalencias dos fatores de risco comportamentais (sedentarismo, dieta aterogenica, tabagismo) e biologicos (excesso de peso, excesso de adiposidade abdominal, pre-hipertensao/hipertensao arterial, hiperglicemia e dislipidemias) e sua associacao com variaveis sociodemograficas (sexo, idade e nivel economico). As associacoes foram testadas por meio do teste qui-quadrado e razao de prevalencia (intervalo de confianca de 95%) entre os fatores de risco e as variaveis sociodemograficas. RESULTADOS: Os fatores de risco mais prevalentes foram: dieta aterogenica (98,3%), sedentarismo (61,2%), excesso de adiposidade abdominal (32,6%), baixos niveis de lipoproteina de alta densidade (25,9%) e colesterol total elevado (20,3%). Foram encontradas associacoes significativas entre sexo feminino, sedentarismo [razao de prevalencia (RP) = 1,33 (1,17 - 1,50)], excesso de adiposidade abdominal [RP = 2,44 (1,89 - 3,16)] e colesterol total elevado [RP = 1,89 (1,36 - 2,62)]; e, entre o sexo masculino, baixos niveis de lipoproteina de alta densidade [RP = 2,22 (1,67 - 2,94)] e pre-hipertensao/hipertensao arterial [RP = 4,87 (1,67 - 14,23)]. Verificou-se tambem,associacao entre a idade de 17 a 19 anos e o tabagismo [RP = 1,84 (1,05 - 3,22)] e pre-hipertensao/hipertensao arterial [RP = 3,36 (1,43 - 7,90)]. O nivel economico nao foi associado aos fatores de risco cardiovascular na amostra estudada. CONCLUSAO: Os resultados indicam a necessidade de intervencoes que promovam um estilo de vida saudavel, com enfase a adocao de habitos alimentares adequados e ao aumento dos niveis de atividade fisica.

The clustering of diet, physical activity and sedentary behavior in children and adolescents: a review

Abstract: This paper reviews studies using empirical, data-driven methodologies, such as cluster analysis and latent class analysis, to identify clustering patterns of diet, physical activity and sedentary behavior among children or adolescents and their associations with socio-demographic indicators, and overweight and obesity.

Living in two worlds: the plant and insect lifestyles of Xylella fastidiosa.

Abstract: Diseases caused by Xylella fastidiosa have attained great importance worldwide as the pathogen and its insect vectors have been disseminated. Since this is the first plant pathogenic bacterium for which a complete genome sequence was determined, much progress has been made in understanding the process by which it spreads within the xylem vessels of susceptible plants as well as the traits that contribute to its acquisition and transmission by sharpshooter vectors. Athough this pathogen shares many similarities with Xanthomonas species, such as its use of a small fatty acid signal molecule to coordinate virulence gene expression, the traits that it utilizes to cause disease and the manner in which they are regulated differ substantially from those of related plant pathogens. Its complex lifestyle as both a plant and insect colonist involves traits that are in conflict with these stages, thus apparently necessitating the use of a gene regulatory scheme that allows cells expressing different traits to co-occur in the plant.
