Nutrition: Whose Responsibility?

The population is spending increasing amounts of money for food away from the home. At the same time people are eating in a more healthful manner. The author discusses what the food service industry can and should do to better meet the needs and demands of consumers.

African American and Hispanic adolescent STI and pregnancy prevention: Whose responsibility is it, anyway?

This dissertation utilized quantitative and qualitative methods to examine the role of responsibility in the prevention of sexually transmitted infections (STIs) and pregnancy through condom use and other sexual behaviors among young adolescents. Data were analyzed across race and gender and three papers were developed. The quantitative portion used logistic regression to assess associations between personal responsibility, as well as other know correlates, and reported condom use and condom use intentions as a means of STI and pregnancy prevention among 445 inner-city, high school adolescents. Responsibility to prevent pregnancy by providing the condom was associated with condom use at last sex and consistent condom use. Responsibility to prevent acquiring a STI by using a condom was significantly associated with consistent condom use. No significant associations were found between responsibility and condom use intentions. ^ The qualitative section of the dissertation project involved conducting 28 in-depth interviews among 9th and 10th grade, African American and Hispanic students who attended a large urban school district in South Central Texas. Perceptions of responsibility for preventing STIs and unintended pregnancy, as well as for condom use, were explored. Male and female adolescents expressed joint responsibility to prevent a STI or pregnancy. Perceptions of responsibility for providing and using the condoms were mixed. Despite the indication of both partners, mostly all participants implied that females, more so than the males, had the final responsibility to prevent contracting a STI, a pregnancy, to provide a condom, and to make sure a condom was used. Participants expressed the role of parents' involvement for preventing these outcomes as well as the need for more sexual health education and access to preventative methods. ^ The last section of this dissertation involved qualitative inquiry to ascertain perceptions of reasons why adolescents engage in anal and oral (non-coital) sex. Pleasure-seeking and giving as well social influence and pressure were described as the main reasons why teenagers have non-coital sex. Other reasons included conveniences of participating in these behaviors such as ease of performing oral sex and anal sex as a convenient alternative to vaginal sex. Sexual inexperience was an indicator for why anal sex occurs. Many of the reasons involved misperceptions and adolescents who practice these sexual behaviors place themselves at-risk for contracting a STI. ^ This dissertation increased the current knowledge base about adolescent sexual responsibility and non-coital behaviors. Future studies should explore perceptions of responsibility and actual sexual activity practices among adolescents to reduce the burden of STIs and pregnancy as well as help public health professionals develop programs for adolescent populations, schools, and communities where these issues persist.^

Öljyvahinkojätteiden käsittely alusonnettomuuden jälkeen Kymenlaakson alueen näkökulmasta

Työn tavoitteena oli selvittää Suomenlahden rannalta merkittävän suuruisen alusöljyvahingon jälkeen kerättävän öljyisen jätteen käsittelymahdollisuudet ja -kapasiteetit sekä loppusijoitusmahdollisuudet ja -kapasiteetit Kymenlaakson alueen näkökulmasta. Tarkoituksena oli selvittää, missä jätteiden käsittely voidaan toteuttaa sekä, miten öljyisiä jätteitä voidaan esikäsitellä välivarastoinnin aikana puhdistuksen ja loppusijoituksen tehostamiseksi. Tutkimuksen kohteena oli sekä rannalta kerättävät kiinteät öljyiset ainekset että öljyinen merivesi. Työn alussa on perehdytty jätehuoltovastuuseen, eli kenen vastuulla öljyalusonnettomuuksissa syntyvät öljyiset jätteet ovat. Työssä on esitelty lyhyesti öljyvahinkojätteille teknisesti soveltuvien käsittelymenetelmien periaatteet ja menetelmien rajoituksia käsitellä öljyvahinkojätetteitä. Työssä on myös mainittu aiemmin Suomea koskettaneiden tai maailmalla tapahtuneiden alusöljyvahinkojen jätemääriä ja tapauksissa käytettyjä jätteiden käsittelymenetelmiä. Työ painottuu esittelemään Kymenlaakson alueen laitosten, Riihimäen Ekokem Oy Ab:n ja siirrettävien laitteistojen mahdollisuuksia käsitellä öljyisiä jätteitä. Lisäksi on esitelty öljyisen meriveden käsittelyyn soveltuvia laitoksia Kymenlaakson alueen näkökulmasta. Tietoja on kerätty puhelimitse ja sähköpostitse yritysten edustajilta vuoden 2007 aikana. Kymenlaakson alueella voidaan polttaa voimalaitosten leijupedeissä puhtaaseen polttoaineeseen sekoitettuja öljyisiä orgaanisia aineksia ja murskautuvia puhdistustyössä käytettyjä varusteita noin 10 000 t/a, homogenoitua öljyistä orgaanista ainesta voidaan polttaa Leca-soratehtaan rumpu-uunissa noin 1 200 t/a. Alueen polttokapasiteetti kasvaa, kun työn aikana rakenteilla oleva jätteenpolttolaitos valmistuu ja jätettä voidaan polttaa laitoksen arinalla. Haihtuvilla öljy-yhdisteillä pilaantuneita maa-aineksia voidaan alipainekäsitellä, jos yhdisteet eivät ole haihtuneet jo merellä. Erityisesti öljyiset maaainekset voidaan käsitellä alhaisilla öljypitoisuuksilla (öljypitoisuus noin alle 1-2 %) bitumistabiloimalla, aumakompostoimalla tai pesemällä siirrettävällä pesulaitteistolla. Kymenlaakson alueelle voidaan tuoda myös alueen ulkopuolelta siirrettäviä laitteistoja. Siirrettävät termodesorptiolaitteistot on tehty pilaantuneen maa-aineksen ensisijaiseen käsittelyyn, mutta samalla voidaan käsitellä myös muita jätejakeita, joilla on pieni partikkelikoko (alle 5-10 cm). Savaterra Oy:n siirrettävän termodesorptiolaitteiston kapasiteettiarvio on 100 000 t/a. Myös Niska & Nyyssönen Oy:llä on siirrettävä termodesorptiolaitteisto. Doranova Oy:n siirrettävän pesulaitteiston kapasiteettiarvio on 30 000- 50 000 t/a öljyistä maa-ainesta. Tutkimuksessa on ollut mukana myös Riihimäen Ekokem Oy Ab:n jätevoimala, jonka kapasiteettiarvio on 40 000-45 000 t/a erityisesti öljyisille orgaanisille aineksille, varusteille ja kuolleille eläimille. Riihimäen Ekokem Oy Ab:n ongelmajätelaitoksen rumpuuuneissa voidaan käsitellä arviolta 80 000-100 000 t/a öljyisiä maa-aineksia eli kiinteitä jätteitä, joiden partikkelikoko on suunnilleen alle 10 cm, ja 20 000 t/a nestemäisiä öljyisiä jätteitä. Työn loppupuolella on esitelty myös öljyisen meriveden käsittelyyn soveltuvia laitoksia ja niiden rajoituksia käsitellä kyseistä jätettä. Kyseisten laitosten kapasiteetit selviävät usein vasta onnettomuuden sattuessa. Kaikkiin annettuihin kapasiteettiarvioihin vaikuttaa merkittävästi jätteen koostumus. Raportin lopussa on esitelty alustava toimintasuunnitelma öljyvahinkojätteen käsittelemiseksi. Suunnitelmaan sisältyvät eri jätejakeille laaditut kaaviot, joista voi nähdä muun muassa eri jätekoostumuksille teknisesti soveltuvat käsittelymenetelmät ja käsittelymenetelmiä suorittavat yritykset. Öljyalusonnettomuuden sattuessa soveltuviin yrityksiin tulee ottaa yhteyttä ja selvittää kyseisellä hetkellä vapaana oleva käsittelykapasiteetti. Raportissa on myös esitelty käsittelykustannuksiin vaikuttavia tekijöitä ja arvioitu aiheutuvia kuljetuskustannuksia. Saadut tutkimustulokset ovat hyödynnettävissä erityisesti Kymenlaakson alueella. Tiedot käsittelymenetelmistä ja niiden rajoitteista ovat hyödynnettävissä valtakunnallisesti.

El desorden territorial en el Área Central de Asturias y la responsabilidad de la Administración Autonómica

En las últimas décadas el núcleo interno del Área Central de Asturias se ha venido configurado como un espacio periurbano en el que la deficiente articulación y control del proceso difusor ha generado un notable desorden territorial; desorden cuya responsabilidad debe atribuirse, en primer lugar, a la propia Administración Autonómica.

Time spent with children and working parents' willingness to medicate ADHD-like behaviors

ADHD, which refers to one of the most common behavioral problems among children, is subject to controversial arguments surrounding its nature and its primary treatment with psychiatric medications. At the heart of the problem are parents, whose responsibility includes providing pivotal information to clinicians for the diagnosis and deciding whether their children will receive medications. This study investigates the relationship between working parents' willingness to medicate ADHD-like behaviors and the time they are able to spend with their children during a regular workday. The importance of time spent with children derives from the observation that it is likely to influence not only parents' judgments of their children's behaviors but the behaviors themselves. The relationship was investigated using a subsample of 551 working parents (452 parents reporting no child with problems and 99 parents reporting child with problems) drawn from a population-based telephone survey of parents in the Miami-Dade and Broward counties of Florida. A series of path analyses, controlling for selected socio-demographic and family variables, showed that spending more time with their children during a regular workday was significantly related to being less willing to medicate ADHD-like behaviors. The association was stronger for parents reporting having a child with emotional and behavioral problems (β = −.20) and faint for other parents (β = −.06). The interpretation of the study findings emphasizes the vagueness surrounding the nature of ADHD and the events and procedures leading to the diagnosing of a child, as well as the delicate situations in which parents find themselves.

Cellular polarity in aging: role of redox regulation and nutrition

Cellular polarity concerns the spatial asymmetric organization of cellular components and structures. Such organization is important not only for biological behavior at the individual cell level, but also for the 3D organization of tissues and organs in living organisms. Processes like cell migration and motility, asymmetric inheritance, and spatial organization of daughter cells in tissues are all dependent of cell polarity. Many of these processes are compromised during aging and cellular senescence. For example, permeability epithelium barriers are leakier during aging; elderly people have impaired vascular function and increased frequency of cancer, and asymmetrical inheritance is compromised in senescent cells, including stem cells. Here, we review the cellular regulation of polarity, as well as the signaling mechanisms and respective redox regulation of the pathways involved in defining cellular polarity. Emphasis will be put on the role of cytoskeleton and the AMP-activated protein kinase pathway. We also discuss how nutrients can affect polarity-dependent processes, both by direct exposure of the gastrointestinal epithelium to nutrients and by indirect effects elicited by the metabolism of nutrients, such as activation of antioxidant response and phase-II detoxification enzymes through the transcription factor nuclear factor (erythroid-derived 2)-like 2 (Nrf2). In summary, cellular polarity emerges as a key process whose redox deregulation is hypothesized to have a central role in aging and cellular senescence.

Nutrition dans la bronchopneumopathie chronique obstructive [Nutrition in chronic obstructive bronchopneumopathy]

The respiratory system and nutrition are linked. Obesity is sometimes seen in chronic obstructive pulmonary disease (COPD), but its prevalence, the morbidity and mortality induced by it are not known. In addition, the prevalence of malnutrition is high in COPD and the more severe the COPD is, the higher percentage of malnutrition is present. Emphysematous patients are more frequently undernourished than those suffering from chronic bronchitis. Malnutrition is the consequence of the hypermetabolism induced by the higher cost of breathing in emphysema. The survival rate of these patients is negatively affected by malnutrition. A careful assessment of nutritional status must be performed in all COPD patients, especially during an episode of acute respiratory failure. When signs of malnutrition are present, a nutritional intervention should be initiated rapidly. An amount of calories sufficient to meet the energy expenditure increased by the disease must be given. Excessive intake may overstress the respiratory system whose functional reserve is limited in COPD. The diet must include a well balanced percentage of fat, carbohydrates and proteins. Preservation of the fat-free mass is the minimum goal to reach in acute respiratory failure. After the resolution of the acute phase, a gain of weight should be attempted within a rehabilitation program.

Consumption and portion sizes of tree nuts, peanuts and seeds in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohorts from 10 European countries

Tree nuts, peanuts and seeds are nutrient dense foods whose intake has been shown to be associated with reduced risk of some chronic diseases. They are regularly consumed in European diets either as whole, in spreads or from hidden sources (e.g. commercial products). However, little is known about their intake profiles or differences in consumption between European countries or geographic regions. The objective of this study was to analyse the population mean intake and average portion sizes in subjects reporting intake of nuts and seeds consumed as whole, derived from hidden sources or from spreads. Data was obtained from standardised 24-hour dietary recalls collected from 36 994 subjects in 10 different countries that are part of the European Prospective Investigation into Cancer and Nutrition (EPIC). Overall, for nuts and seeds consumed as whole, the percentage of subjects reporting intake on the day of the recall was: tree nuts = 4. 4%, peanuts = 2.3 % and seeds = 1.3 %. The data show a clear northern (Sweden: mean intake = 0.15 g/d, average portion size = 15.1 g/d) to southern (Spain: mean intake = 2.99 g/d, average portion size = 34.7 g/d) European gradient of whole tree nut intake. The three most popular tree nuts were walnuts, almonds and hazelnuts, respectively. In general, tree nuts were more widely consumed than peanuts or seeds. In subjects reporting intake, men consumed a significantly higher average portion size of tree nuts (28.5 v. 23.1 g/d, P<0.01) and peanuts (46.1 v. 35.1 g/d, P<0.01) per day than women. These data may be useful in devising research initiatives and health policy strategies based on the intake of this food group.

Child labour in India

This thesis entitled “Child labour in india”Children are "supremely important assets" of the nation, India proudly asserts in the National Policy for Children (1974) gracefully acknowledging that they are future citizens on whose shoulders the destiny of our nation rests.Childhood is a time of discovery as the world and all it contains are new to children. It is a time of excitement and anticipation. lt is a time of dreams and fantasies. And it is a time of receiving love and appreciation. Paradoxically, a picture of contrast is a common experience in India as a vast majority of children who are starved of basic needs of nutrition, health and education are made to work at an early age in exploitative conditions. The specter of child labour is a glaring anomaly in a country graciously adorning human right. In an exposition of the problem involving human rights abuse, Chapters from Two to Five of this study have shot into focus the human rights jurisprudence with special reference to the rights of children. Children have a particular identity as children and they also have a universal identity as human beings.The concern for mankind expressed unequivocally and transcending the globe will be real and moving and not mere rhetoric and ritual if and only when it begins with children, as, to quote the words of Nehru, the human being counts much more as a child than as a grown up.The first three of these rights namely right to health, right to nutritive food and right to education are dealt with in Chapter Four. Finally, the positive effects of education have been sketched in that chapter to impress upon its significance in the development of human capitals.legitimization. The theme of legitimacy was rationalised on the ground of poverty as a strategy for achieving eradication of child labour ultimately by enforcing minimum wages, shorter working hours, leave compensation, non-formal education etc., as the employer would soon discover that child labour is not cheap and would be obliged to substitute adult labour. However, humanising the work life is only a promise to the detriment of children as the Act of 1986 enacted as a part of the new strategy is nearingcompletion of a decade of existence but nowhere near the fulfilment of the mission.As similar urge is more necessary and overdue, it has been suggested that a special body be established with all powers for cognisance of human rights abuse of children.It is proposed to conclude this study with a brief summary of the inferences drawn from the foregoing chapters along with a few suggestions emerging out of those inferences

'Response and Responsibility: Theories of the Implied Reader in Children's Literature Criticism'

Reader Response Theory remains popular within Children's Literature Criticism. It seems to offer a sensible resolution to the question of whether meaning derives from text or reader. Through a close reading of one example of this criticism, I suggest that its dualisms are constantly collapsing into appeals to singular authority. at various stages the text or the reader is wholly responsible for meaning. I further suggest that the criticism bypasses the question of interpretation through claiming knowledge of a child reader whose opinions and reactions can be unproblematically accessed. We do not have to worry about reading texts, because we can, apparently, know the child's response to them with certainty. Anything other than this claim to certainty is taken to be a failure of responsibility, a wallowing in the subjective, obscure and perverse. My intention is to reinstate reading as the responsibility of criticism.

Speech acts, responsibility and commitment in poetry

Philosophy has tended to regard poetry primarily in terms of truth and falsity, assuming that its business is to state or describe states of affairs. Speech act theory transforms philosophical debate by regarding poetry in terms of action, showing that its business is primarily to do things. The proposal can sharpen our understanding of types of poetry; examples of the ‘Chaucer-Type’ and its variants demonstrate this. Objections to the proposal can be divided into those that relate to the agent of actions associated with a poem, those that relate to the actions themselves, and those that relate to the things done. These objections can be answered. A significant consequence of the proposal is that it gives prominence to issues of responsibility and commitment. This prominence brings philosophical debate usefully into line with contemporary poetry, whose concern with such issues is manifest in characteristic forms of anxiety.

Whose peace? Local ownership and UN peacebuilding

In recent years, there has been an increasing emphasis on the participation of national actors in United Nations peace operations, reflecting what has become a near orthodox commitment to ‘local ownership.’ Advocates of local ownership assert that it: (1) increases the legitimacy of UN peacebuilding efforts; (2) increases the sustainability of peacebuilding activities after the departure of the UN; and (3) increases democratic governance in post-conflict states. While such thinking about local ownership has informed UN peacebuilding policy to a large extent, the UN has, to date, assumed these positive benefits without critically examining the causal mechanisms that allegedly produce them, specifying the conditions under which this correlation holds, or providing convincing evidence for these assertions. Moreover, exactly what local ownership is, what is being owned, and who local ‘owners’ are remain unclear. Indeed a closer examination of ownership’s relation with legitimacy, sustainability, and democratization reveal a plethora of contradictions that imply that local ownership may in fact decrease the UN’s ability to deliver peacekeeping results. Crucially, however, the UN persists in adopting a local ownership approach to peacebuilding, suggesting that it does so because it is normatively appropriate rather than operationally effective.

Maternal nutrition and oral health factors in early childhood caries

Background. Early Childhood Caries (ECC) is the most common chronic infectious disease of childhood worldwide. Seven of ten American children have one or more decayed or filled primary teeth by age five. ECC prevalence is especially high in lower socio-economic ethnic populations. Commonly recognized as a diet-induced disease, focal etiological factors include cariogenic bacteria, fermentable carbohydrates, and a susceptible newly erupted tooth. Sequencing of breast and/or bottle feeding and introduction of beikost come at a time when children's defense mechanisms and, perhaps maternal direction of children's dietary patterns, are not yet fully developed or mature. To date, most research has examined biological factors, while maternal factors, especially psychosocial ones, have received scant attention. Objective. To examine the association of psychosocial factors in terms of maternal nutrition and oral health knowledge, attitudes, and beliefs, as well as social support and self-efficacy (KABS2) in a population of socio-economically disadvantaged infants and young children. A secondary aim was to describe ECC prevalence in this population. Methods. This study examined cross-sectionally the relationship between selected maternal psychosocial variables and ECC in a convenience sample of Mexican-American women and very young children participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in San Antonio, Texas. Mothers were surveyed by use of a criteria- and content-valid, reliable questionnaire, and dental examinations were conducted on 191 children, aged 5 to 47 months old. Results. Thirty-nine percent of the children had ECC. As assessed on a 30-question scale, women in whose children were diagnosed with ECC were found to demonstrate lower Knowledge ( p=0.03), Attitudes (p=0.02), Beliefs (p=0.04), and Social Support (p<0.01) scores, compared to women whose children were found to be caries-free. No differences in Self-Efficacy scores were found between the groups. Conclusions. These data indicate that current etiological model depicting relevant factors associated with ECC in Mexican-American infants and children of low socio-economic status should be broadened to include consideration of maternal psychosocial factors such as nutrition and oral health knowledge, attitudes, beliefs, and social support, and that these factors should be considered when planning educational approaches to reduce the occurrence of ECC. ^
