Comparison of Physicochemical, Organoleptic and Nutritional Abilities of Eight Sweet Potato (Ipomoea batatas) Varieties  [PDF]
Emy Njoh Ellong, Corinne Billard, Sandra Adenet
Food and Nutrition Sciences (FNS) , 2014, DOI: 10.4236/fns.2014.52025
Abstract:

In Martinique (F.W.I.), biodiversity of vegetable varieties remain unexploited due to public unawareness or supply problems. To further enhance the sweet potato, physicochemical, sensory and nutritional characteristics of eight varieties of sweet potato were established. The eight sweet potatoes cultivars were noticeably diverse with phenotypic, sensory, physicochemical and nutritional characteristics which were very varied. The eight cultivars grown in Martinique were advantageously positioned in relation to the globally identified sweet potato, regarding fibre, starch, potassium, copper, vitamin B1, B3 and B9 contents. Compared to the ordinary potato, Martiniquan sweet potatoes have a much better nutritional potential. Energy value and vitamin C levels were twice as much as in normal potatoes. Martiniquan sweet potatoes cultivars were also richer in minerals and vitamins, with 2.7 times more vitamin B9 and 63 times more beta-carotene than the ordinary potato.

Physicochemical, Nutritional, Organoleptic Characteristics and Food Applications of Four Mango (Mangifera indica) Varieties  [PDF]
Emy Njoh Ellong, Sandra Adenet, Katia Rochefort
Food and Nutrition Sciences (FNS) , 2015, DOI: 10.4236/fns.2015.62025
Abstract: Physicochemical characteristics of four varieties of mango (Julie, Bassignac, Green and Moussache) from Martinique (F.W.I.) were examined at three ripening stages. All ripening protocols studied showed an evolution in parameters between the harvesting and the expandable stage. Fruit and pulp firmness, starch and vitamin C contents decreased whereas pulp pH and carotenoids content increased. Only fruit size and polyphenols content were the same during the ripening. Bassignac and Julie varieties were richer in vitamin C, polyphenols and carotenoids. Moussache variety was the most energetic with important carbohydrates content. The Green variety differed significantly with a light-coloured pulp, low fruity odour and mango flavour, and a specific slightly sweet, very sour, bitter and astringent taste. Moussache and Bassignac varieties had a very sweet taste unlike the Julie variety with a specific slightly sweeter taste. Different processing methods were tested for each variety. Mangoes technological ability processing had been validated.
Polyphenols, Carotenoids, Vitamin C Content in Tropical Fruits and Vegetables and Impact of Processing Methods  [PDF]
Emy Njoh Ellong, Corinne Billard, Sandra Adenet, Katia Rochefort
Food and Nutrition Sciences (FNS) , 2015, DOI: 10.4236/fns.2015.63030
Abstract: Thirty-five fruits and seventeen vegetables from Martinique were evaluated for total phenol content (TPC), Vitamin C and carotenoid content. TPC, Vitamin C and carotenoid contents ranged from 11.7 to 978.6 mg/100g, 0.1 to 2853.8 mg/100g and 9.7 to 9269.7 μg/100g respectively. Fruits and vegetables from Martinique have equivalent or higher TPC, Vitamin C and carotenoid contents than fruits and vegetables from temperate climates. Cashew apple had high values for all three parameters (55.8 mg/100g of Vitamin C, 603 mg/100g of TPC and 924 μg/100g of carotenoids). Bassignac mango and mamey apple had the highest carotenoid contents, with 3800.3 and 3199.7 μg/100g respectively. Acerola had the highest Vitamin C and polyphenol contents with 2853.8 μg/100g and 727.4 mg/100g respectively. Pigeon peas had high values for all three parameters (569.2 mg/100g of Vitamin C, 978.6 mg/100g of TPC and 364.3 μg/100g of carotenoids). Pumpkin and watercress had the highest carotenoid content, with 9269.7 and 4339 μg/100g respectively. TPC, Vitamin C and carotenoid content were significantly impacted by processing techniques. TPC, Vitamin C and carotenoid contents decreased by up to 75.78%, 100% and 70.18% respectively, depending on the processing technique used.
Territoires ruraux insulaires et développement durable

Abstract: Après avoir rappelé que comme concept de gestion des territoires, le développement durable peut s’inscrire dans un système territorial complexe, l’article s’interroge sur les imaginaires associés à la ruralité et à l’insularité. Largement issue du regard de nos sociétés urbaines, la critique des abus d’un modèle de développement insulaire peu respectueux d’un environnement détérioré et/ou à l’abandon, conduit à promouvoir une gestion des territoires intégrant également une dimension économique et socioculturelle, notamment un fort mouvement de patrimonialisation , sorte de réinvention de l’ le mythique, symbole d’un équilibre passé. Divers exemples ( le grecque de Skopelos, Corse, Martinique) montrent que ressources et savoir-faire spécifiques, difficilement transposables en dehors du contexte insulaire, peuvent être considérés comme un atout pour le développement ; ils renforcent l’identité d’une communauté et inspirent des dynamiques sociales renouvelées. Pour autant, il importe de réfléchir aux interactions entre des filières qui partagent les mêmes lieux, les mêmes ressources et impliquent les mêmes personnes. A l’évidence, la qualité du lien social augmente la résilience du système territorial même si cela passe par une redéfinition des règles collectives qui visent à inventer des solidarités durables passant davantage par des savoir-être ensemble que par des savoir-faire purement techniques. As a concept of territorial management, sustainable development can be analysed in the systemic vision allowed by complex territorial systems. This article wonders about the representations associated to rural areas and insularity. Largely encouraged by our modern societies, the critical vision of island development – not environmentally friendly models – promotes an integrated vision of development aiming at combining economical and sociocultural considerations. The great movement of cultural heritage, sort of reinvention of mythic islands symbolising a past equilibrium is then progressively supported. Different examples dealt with in this article (The Greek island of Skopelos, Corsica, Martinique) show that resources and specific know-how, not easily transferable out of the insular context, can be considered as strong advantages for development. They reinforce communities’ identity and favour new social dynamics. Obviously, quality ties increase the resilience of the territorial system even though it necessitates to redefine collective rules that aim at inventing sustainable solidarity relying mainly on knowing how to behave instead of pure technical know
Investigating the Suitability of Agile Methods for Requirements Development of Home Care Systems  [PDF]
Sandra Kelly, Frank Keenan
Journal of Software Engineering and Applications (JSEA) , 2010, DOI: 10.4236/jsea.2010.39104
Abstract: The ageing population in developed countries brings many benefits but also many challenges, particularly in terms of the development of appropriate technology to support their ability to remain in their own home environment. One particular challenge reported for such Home Care Systems (HCS) is the identification of an appropriate requirements development technique for dealing with the typical diverse stakeholders involved. Agile Methods (AMs) recognize this challenge and propose techniques that could be useful. This paper examines the desirable characteristics identified for requirements development in HCS and investigates the extent to which agile practices conform to these. It also sets out future work to improve the situation for the non compliant points found.
Recent Developments in the Nasal Immunization against Anthrax  [PDF]
Sandra Jesus, Olga Borges
World Journal of Vaccines (WJV) , 2011, DOI: 10.4236/wjv.2011.13008
Abstract: Bacillus anthracis is the causative agent of anthrax, a bacterial infection with a high mortality rate [1-3]. Although anthrax infection can be cutaneous, gastrointestinal or pulmonary, the pulmonary form is the most deadly [2,3]. Thus, the release of Bacillus anthracis spores that can be inhaled represents a potent bioterrorism threat; the capacity of B. anthracis spores to act as a bioterrorism weapon was demonstrated in 2001, with the intentional infection of 22 persons in the U.S.A. [2,4]. Until recently, the available vaccines were developed to confer protection against cutaneous infection; despite this, these vaccines demonstrated experimental efficacy against pulmonary infection in multiple animal models [1,2]. Nevertheless, there are many limitations for these vaccines to be considered successful and effective vaccine, including the intensity of the required vaccination schedule, the administration route and the presence of local adverse effects experienced after vaccination [1,3,5,6]. To develop more efficient vaccines against pulmonary anthrax, intranasal formulations with adjuvant have been studied. These formulations have advantages because they are easy to administer and because they are expected to induce both systemic and respiratory tract mucosal immune responses. Therefore, the main goal of this review is to compare the different experimental adjuvants used with anthrax antigens and the different approaches regarding the vaccination schedule and consecutive boosters.
Effect of Breed and Sex on Pork Meat Sensory Evaluation  [PDF]
Sandra Rodrigues, Alfredo Teixeira
Food and Nutrition Sciences (FNS) , 2014, DOI: 10.4236/fns.2014.57070
Abstract:

This work had an objective to evaluate the sensory quality of two categories of pork meat from a commercial pork meat and a selected meat from the Portuguese black pork (Preto Alentejano breed). Sixteen animals were used, 8 females and 8 males from each breed. Animals had 80 - 100 kg of live weight. The longissimus muscle between the 5th thoracic vertebra and the 10th lumbar vertebra was used in the analysis. Sensory analysis was performed by a trained taste panel of 10 elements, in 5 sessions. All evaluation conditions were standardized, and the attributes studied were odor intensity, toughness, juiciness and flavor intensity. The taste panel found differences mainly between breeds. The panellists scored Preto Alentejano meat as being juicier, tenderer, and with richer taste than Commercial meat. The higher juiciness score of Preto Alentejano meat was probably attributable to the higher intramuscular fat content compared with Commercial meat. The Commercial pork was characterized mainly by high toughness.

Trends in U.S. Voting Attitudes with a Consideration of Variation by Gender and Race/Ethnicity  [PDF]
Sandra L. Hanson
Open Journal of Political Science (OJPS) , 2016, DOI: 10.4236/ojps.2016.64038
Abstract: Low turnout rates and discussions of disaffected voters are receiving considerable attention as we approach the 2016 U.S. presidential elections. Do trends in American’s attitudes about voting and correlates of these attitudes (political involvement, efficacy, and social connectedness) confirm the pessimistic assessments and do voters across gender and race/ethnic groups think similarly? Data from the American National Election Studies (ANES) provide some reason for optimism. Trends over the past few presidential election periods show a majority of Americans intend to vote and this majority is increasing. Trends show increases or stability on numerous correlates of voting attitudes including political involvement and social connectedness. Trends in voting attitudes by gender and race/ethnicity show considerable variation. Women and race/ethnic minorities (especially African Americans) are an important element of the positive trends shown here. Findings on external efficacy are an exception to the generally optimistic trends with data showing a majority of respondents don’t believe public officials care what people like the respondent think. However, trends do not show an increase in negative attitudes about public officials. Implications of the findings are considered.
Early Children’s Literature and Aging  [PDF]
Sandra L. McGuire
Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.717245
Abstract: Increased longevity is a worldwide phenomenon placing emphasis on the need for preparation for life’s later years and for maximizing the potentials of these years. Today’s children will be the older adults of tomorrow. A resource that can help to educate them about aging and prepare them for the long life ahead is early children’s literature (Preschool-Primary). This literature can provide children with a holistic view of aging, teach them about aging and the aging process, promote positive attitudes about aging, and promote positive aging. Selecting early children’s literature for aging content, resources for finding early children’s literature to promote positive aging, and examples of early children’s literature to promote positive aging are presented.
Aging Education: A Worldwide Imperative  [PDF]
Sandra L. McGuire
Creative Education (CE) , 2017, DOI: 10.4236/ce.2017.812128
Abstract: Life expectancy is increasing worldwide. Unfortunately, people are generally not prepared for this long life ahead and have ageist attitudes that inhibit maximizing the “longevity dividend” they have been given. Aging education can prepare people for life’s later years and combat ageism. It can reimage aging as a time of continued growth, development?and?fulfillment. Unfortunately, aging education is not a common occurrence. This education needs to begin with children and continue throughout life. This article discusses why we need to teach about aging?and?aging education content, suggests a conceptual framework for aging education, and presents aging education resources. The concept of ageism is discussed and suggestions for combating ageism are proposed.
