The importance of mealtime structure for reducing child food fussiness

The aim of this study was to explore how the structure of mealtimes within the family setting is related to children's fussy eating behaviours. Seventy-five mothers of children aged between 2 and 4 years were observed during a typical mealtime at home. The mealtimes were coded to rate mealtime structure and environment as well as the child's eating behaviours (food refusal, difficulty to feed, eating speed, positive and negative vocalisations). Mealtime structure emerged as an important factor which significantly distinguished children with higher compared with lower levels of food fussiness. Children whose mothers ate with their child and ate the same food as their child were observed to refuse fewer foods and were easier to feed compared with children whose mothers did not. During mealtimes where no distractors were used (e.g. no TV, magazines or toys), or where children were allowed some input into food choice and portioning, children were also observed to demonstrate fewer fussy eating behaviours. Findings of this study suggest that it may be important for parents to strike a balance between structured mealtimes, where the family eats together and distractions are minimal, alongside allowing children some autonomy in terms of food choice and intake.

Online-questionnaire design:establishing guidelines and evaluating existing eupport

As a new medium for questionnaire delivery, the internet has the potential to revolutionise the survey process. Online (web-based) questionnaires provide several advantages over traditional survey methods in terms of cost, speed, appearance, flexibility, functionality, and usability [1, 2]. For instance, delivery is faster, responses are received more quickly, and data collection can be automated or accelerated [1- 3]. Online-questionnaires can also provide many capabilities not found in traditional paper-based questionnaires: they can include pop-up instructions and error messages; they can incorporate links; and it is possible to encode difficult skip patterns making such patterns virtually invisible to respondents. Like many new technologies, however, online-questionnaires face criticism despite their advantages. Typically, such criticisms focus on the vulnerability of online-questionnaires to the four standard survey error types: namely, coverage, non-response, sampling, and measurement errors. Although, like all survey errors, coverage error (“the result of not allowing all members of the survey population to have an equal or nonzero chance of being sampled for participation in a survey” [2, pg. 9]) also affects traditional survey methods, it is currently exacerbated in online-questionnaires as a result of the digital divide. That said, many developed countries have reported substantial increases in computer and internet access and/or are targeting this as part of their immediate infrastructural development [4, 5]. Indicating that familiarity with information technologies is increasing, these trends suggest that coverage error will rapidly diminish to an acceptable level (for the developed world at least) in the near future, and in so doing, positively reinforce the advantages of online-questionnaire delivery. The second error type – the non-response error – occurs when individuals fail to respond to the invitation to participate in a survey or abandon a questionnaire before it is completed. Given today’s societal trend towards self-administration [2] the former is inevitable, irrespective of delivery mechanism. Conversely, non-response as a consequence of questionnaire abandonment can be relatively easily addressed. Unlike traditional questionnaires, the delivery mechanism for online-questionnaires makes estimation of questionnaire length and time required for completion difficult1, thus increasing the likelihood of abandonment. By incorporating a range of features into the design of an online questionnaire, it is possible to facilitate such estimation – and indeed, to provide respondents with context sensitive assistance during the response process – and thereby reduce abandonment while eliciting feelings of accomplishment [6]. For online-questionnaires, sampling error (“the result of attempting to survey only some, and not all, of the units in the survey population” [2, pg. 9]) can arise when all but a small portion of the anticipated respondent set is alienated (and so fails to respond) as a result of, for example, disregard for varying connection speeds, bandwidth limitations, browser configurations, monitors, hardware, and user requirements during the questionnaire design process. Similarly, measurement errors (“the result of poor question wording or questions being presented in such a way that inaccurate or uninterpretable answers are obtained” [2, pg. 11]) will lead to respondents becoming confused and frustrated. Sampling, measurement, and non-response errors are likely to occur when an online-questionnaire is poorly designed. Individuals will answer questions incorrectly, abandon questionnaires, and may ultimately refuse to participate in future surveys; thus, the benefit of online questionnaire delivery will not be fully realized. To prevent errors of this kind2, and their consequences, it is extremely important that practical, comprehensive guidelines exist for the design of online questionnaires. Many design guidelines exist for paper-based questionnaire design (e.g. [7-14]); the same is not true for the design of online questionnaires [2, 15, 16]. The research presented in this paper is a first attempt to address this discrepancy. Section 2 describes the derivation of a comprehensive set of guidelines for the design of online-questionnaires and briefly (given space restrictions) outlines the essence of the guidelines themselves. Although online-questionnaires reduce traditional delivery costs (e.g. paper, mail out, and data entry), set up costs can be high given the need to either adopt and acquire training in questionnaire development software or secure the services of a web developer. Neither approach, however, guarantees a good questionnaire (often because the person designing the questionnaire lacks relevant knowledge in questionnaire design). Drawing on existing software evaluation techniques [17, 18], we assessed the extent to which current questionnaire development applications support our guidelines; Section 3 describes the framework used for the evaluation, and Section 4 discusses our findings. Finally, Section 5 concludes with a discussion of further work.

Editorial

Full text: There are phrases in daily use today which were not so common a decade or so back, such as ‘ageing population’ or ‘climate changes’ or ‘emerging markets’ or even ‘social networking’. How do these things affect our lives is certainly interesting but for us as eye care practitioners how these changes affect our clinical work may be also relevant and sometimes more interesting. A recent advertisement for recruitment to the Royal Marine Corps of the British Army ended with a comment ‘find us on Facebook!’ The BCLA, IACLE and other organisations as well as many manufacturers have their own Facebook groups. In 2011 Chandni Thakkar was awarded the BCLA summer studentship and her project was based around increasing the contact lens business of a small independent optometric practice where contact lens sales were minimal. The practice typically recruited one new wearer per month. Chandni was able to increase the number of new patient fits with various strategies (her work was presented as poster at the 2012 BCLA conference in Birmingham). One of her strategies was to start a Facebook group and 655 joined the special group she started in just over a month. Interestingly she found that the largest single factor in convincing patients to trial contact lenses was recommendation by the eye care practitioner at the end of the examination, but nonetheless it is interesting that so many people used the social networking site to find out more information regarding contact lenses in her study. Moreover, we already see the use, by some practitioners, of smart phone ‘apps’ or electronic diaries or text messages when coordinating patient check-ups. Climate change has affected the way we think and act; we now leave out special recycle bins and we hope that the items that are recyclable are actually recycled and do not just join our other refuse somewhere down the track! How environmentally friendly are contact lenses? This was discussed by various speakers at this year's BCLA conference in Birmingham. Daily disposable lenses surely produce more contact lens waste but do not involve solutions in plastic bottles like monthly lenses. It is certainly something that manufacturers are taking seriously and of course there are environmental benefits but the cynic in each of us sees the marketing potential too. The way the ageing population is certainly something that will impact all healthcare providers. In the case of eye care with people living longer they will need refractive corrections for longer. Furthermore, since presbyopes are not resigning themselves to only gentle hobbies like knitting and gardening, but instead want to continue playing tennis or skiing or whatever, their visual demands are becoming more complex. This is certainly an area that contact lens manufacturers are focussing on (pun not intended!). Again the BCLA conference in Birmingham saw the launch of various new products by different companies to help us deal with our presbyopic contact lens wearers. It is great to have such choice and now with fitting methods becoming easier too we have no excuse not to try them out with our clients. Finally to emerging markets – well there was not a specific session at the BCLA conference in May discussing this but this most certainly would have been discussed by professional services managers and marketing directors of most of the contact lens companies. ‘How will we conquer China?’ ‘How can we increase our market share in Russia?’ Or ‘How should we spend our marketing budget in India?’ These topics as well as others would certainly have cropped up in backroom discussions. Certainly groups like IACLE (International Association of CL Educators) have increasing numbers of members and activities in developing markets to ensure that educators educate, to that practitioners can practice successfully and in turn patients can become successful contact lenses wearers. Companies also wish to increase their market share in these developing markets and from the point of view of CLAE we are certainly seeing more papers being submitted from these parts of the world. The traditional centres of knowledge are being challenged, I suppose as they have been throughout history, and this can only be a good thing for the pursuit of science. The BCLA conference in Birmingham welcomed more international visitors than ever, and from more countries, and long may that continue. Similarly, CLAE looks forward to a wider audience in years to come and a wider network of authors too.

Supercritical water gasification of RDF and its components over RuO2/γ-Al2O3 catalyst:new insights into RuO2 catalytic reaction mechanisms

Five samples including a composite refuse derived fuel (RDF) and four combustible components of municipal solid wastes (MSW) have been reacted under supercritical water conditions in a batch reactor. The reactions have been carried out at 450 °C for 60 min reaction time, with or without 20 wt% RuO2/gamma-alumina catalyst. The reactivities of the samples depended on their compositions; with the plastic-rich samples, RDF and mixed waste plastics (MWP), giving similar product yields and compositions, while the biogenic samples including mixed waste wood (MWW) and textile waste (TXT) also gave similar reaction products. The use of the heterogeneous ruthenium-based catalyst gave carbon gasification efficiencies (CGE) of up to 99 wt%, which was up by at least 83% compared to the non-catalytic tests. In the presence of RuO2 catalyst, methane, hydrogen and carbon dioxide became the dominant gas products for all five samples. The higher heating values (HHV) of the gas products increased at least two-fold in the presence of the catalyst compared to non-catalytic tests. Results show that the ruthenium-based catalyst was active in feedstock steam reforming, methanation and possible direct hydrogenolysis of C-C bonds. This work provides new insights into the catalytic mechanisms of RuO2 during SCWG of carbonaceous materials, along with the possibility of producing high yields of methane from MSW fractions.

Age Differences among Female Sex Workers in the Philippines: Sexual Risk Negotiations and Perceived Manager Advice

Consistent condom use among high risk groups such as female sex workers (FSWs) remains low. Adolescent female sex workers are especially at higher risk for HIV/STI infections. However, few published studies have compared the sexual risk negotiations among adolescent, emerging adult, and older age groups or the extent a manager’s advice about condom use is associated with an FSW’s age. Of 1,388 female bar/spa workers surveyed in the southern Philippines, 791 FSW who traded sex in the past 6 months were included in multivariable logistic regression models. The oldest FSWs (aged 36–48) compared to adolescent FSWs (aged 14–17) were 3.3 times more likely to negotiate condoms when clients refused condom use. However, adolescent FSWs received more advice from their managers to convince clients to use condoms or else to refuse sex, compared to older FSWs. Both adolescent and the oldest FSWs had elevated sexually transmitted infections (STIs) and inconsistent condom use compared to other groups. Having a condom rule at the establishment was positively associated with condom negotiation. Factors such as age, the advice managers give to their workers, and the influence of a condom use rule at the establishment need to be considered when delivering HIV/STI prevention interventions.

Ativismo Vegano em Natal: uma etnografia de mobilização política, alimentação ética e identidades

This research has vegan groups in the city of Natal-RN as interlocutors, although I also report to other research contexts, such as those located in the cities of Recife (Pernambuco State) and Campina Grande (Paraíba State). Moved by ethical principles based on animal rights, vegans refuse to consume any product with animal origin. To the extent that consumption habits can be considered powerful elements of identification, the relationship between consumption, food, identity, and politics is an important analytical key in the development of this work. As my main theoretical question, I follow the ways by which the vegan discourse (of abolitionist character) takes shape and materializes into actions, demonstrations and political mobilization. Therefore, I aim to present an ethnography of activities performed collectively by these individuals, such as those of a more ludic character (picnics, etc.) as well as those more politically oriented, especially protests and demonstrations in public places.

Autonomy-Oriented Social Movements and the Politics of Affect

Abstract This dissertation explores damaging tendencies that exist within autonomy-oriented activism in the West. I examine how affect shapes the way that internal conflict is approached and internal strife is dealt with in radical communities. I adopt Sara Ahmed’s proposition “that our emotions are bound up with the securing of the social hierarchy” (Ahmed, 2004b: 4) and given that autonomy-oriented practices are committed to dismantling existing hierarchies, it follows that the less oppressive social configurations sought by autonomous social movements must have different emotional underpinnings. My thesis involves applying critical theory on affect and emotion in social movements to interview data gathered from activists both currently and historically involved in autonomy-oriented social movement communities in Kingston, Ontario. I ask whether anglophone, western-based, autonomy-oriented social movements reproduced understandings of affect/emotions/feelings that underwrite the social order they are working against? I also ask, “how are our emotions conditioned by capitalism?”. The research that I engage with provides responses to these questions by pointing out how the dominant discourse on emotions in the West encourages and informs certain modes of identity production that affect the diminishing and sad practices of autonomy-oriented communities and the (re)production of oppressive practices found in the dominant order. My work critically places this psychologizing view of emotions, and its damaging effects on resistance, within the context of neoliberal capitalism. I argue that the way we understand the politics of affect is an important dimension of radical struggle, and will inform and impact upon our individual and collective capacities to respond to, and refuse to reproduce relations of control and domination. I look for an understanding of “why” and to “what extent” these determinations exists, and look for hope in a politics of affect which supports an autonomy-oriented ethic.

Relações de Vinculação dos Jovens Institucionalizados com os Cuidadores Formais

No quadro da teoria da vinculação, é possível estabelecer relações de vinculação ao longo de toda a vida, sendo que, apesar dos jovens institucionalizados rejeitarem estabelecer novas relações de vinculação numa fase inicial, acabam por procurá-las, desde que essa figura desempenhe funções de cuidador responsivo, de modo estável e apoiante. Este estudo tem como objetivo principal perceber se as crianças e jovens acolhidos em Lares de Infância e Juventude (LIJ) estabelecem relações de vinculação com os cuidadores formais e compreender como essa relação foi construída. Foram utilizados os questionários Important People Interview (IPI; Kobak e Rosenthal, 2010) e Hierarquização das Figuras Significativas por Campos de Vida (HFSCV), criado para incluir os jovens que consideram não terem desenvolvido relações de vinculação com os cuidadores formais do LIJ. Foi, ainda, realizada uma entrevista semiestruturada. Apesar de usarmos uma metodologia quantitativa para análise dos resultados dos dois primeiros questionários, esta investigação prima sobretudo pela abordagem qualitativa, através do recurso à técnica de análise conteúdo das entrevistas. O estudo foi realizado no LIJ “Comunidade Juvenil de São Francisco de Assis”, localizado em Coimbra, contando com a participação de 16 jovens de ambos os géneros, com idades entre os 13 e os 19 anos (M=16; DP=1,8), com tempo de permanência no LIJ igual ou superior a 2 anos contínuos. Estes 16 jovens constituem a amostra total da investigação, sobre a qual incidiu a primeira parte do estudo (abordagem quantitativa), ao que se seguiu a segunda parte do estudo (abordagem qualitativa), que contou com a participação de uma subamostra de 11 jovens, pertencentes à amostra total. Os resultados sugerem que a maioria dos jovens estabeleceu relações de vinculação com os cuidadores formais do LIJ, sendo que a maioria das hierarquias das figuras de vinculação foram constituídas com base nos laços de familiaridade e na ligação afetiva com os seus cuidadores formais. Os jovens destacaram a compreensibilidade, confiabilidade e disponibilidade para o auxílio como sendo as características que determinaram a sua preferência em relação aos cuidadores formais do LIJ. Refira-se, ainda, que as situações que ativam a procura destas figuras estão relacionadas com a necessidade de apoio e proteção. O presente estudo sugere que é possível um LIJ promover relações semelhantes às desenvolvidas em meio familiar e atuar de forma reparadora ao nível das relações de vinculação. / In the attachment theory framework, one can establish attachment relationships throughout one's life. In the case of institutionalized youngsters, even though at first they seem to refuse new attachment relationships, these adolescents end up looking for them, if the person is perceived as a responsive, stable and supportive caregiver. The main goal of this study is to understand whether children and young people taken into Child and Youth Residential Care establish attachment relationships with formal caregivers and, if so, understand how that relationship is built. We have used the questionnaires Important People Interview (IPI; Kobak & Rosenthal, 2010) and Hierarquização das Figuras Significativas por Campos de Vida (HFSCV) (Hierarchization of Significant Figures by Life Fields), created to include the youngsters who consider not have developed attachment relations with Residential Care's formal caregivers. We have also conducted a semi-structured interview. Even though we used a quantitative methodology to process the results of the two inquiries, this research nevertheless privileges a qualitative approach, thorough the technique of analysis of interview content. The study was conducted at the “Comunidade Juvenil de São Francisco de Assis” residential care institution, in Coimbra, Portugal. It had the participation of 16 youngsters of both genders, with ages between 13 and 19 (M=16; DP=1,8), who had been staying at the home for two or more years, non-interrupted. These 16 adolescents are therefore the total sample for this study, and all of them were submitted to the first part (the quantitative approach) of the research. For the second part (the qualitative approach) we worked with a subsample of 11 youngsters, chosen from the initial sample of 16. Results suggest that most young people have indeed developed attachment relationships with residential care's formal caregivers, and most hierarchies of attachment figures were built based on familiarity and affection bonds with their formal caregivers. The subjects have highlighted understanding, trustworthiness and helpfulness as the features that best determine their preference regarding formal caregivers. We must note that the need for protection and support is what enables young people to look out for attachment figures the most. The current study suggests that it is possible for Child and Youth Residential Care to promote relationships similar to those developed in family environment and acts as repairing in what concerns attachment relationships.

Produção de CDR a partir de resíduos industriais: caso de estudo da Recivalongo

A produção de combustível derivado de resíduos (CDR) resultou de uma decisão política que permitiu a instalação em Portugal de um significativo conjunto de processos, cuja avaliação técnico-económica e ambiental pode já ser feita. Este trabalho faz uma avaliação técnica e ambiental da linha de produção de CDR da Recivalongo. A avaliação técnica consistiu na análise dos caudais de material que entraram na linha de produção, na quantidade de CDR produzido, contabilizando também os gastos de recursos da linha (energia e materiais auxiliares). A avaliação da qualidade de CDR produzido a partir do ensaio laboratorial representou também uma parte muito significativa do trabalho produzido. A avaliação ambiental foi efetuada com base na metodologia da Avaliação de Ciclo de Vida (ACV). Os resultados obtidos permitiram concluir que o processo da Recivalongo transforma 69% do material de entrada, recuperando 2% em metais ferrosos e rejeitando para aterro a restante fração de 29%. As análises efetuadas ao CDR mostraram que apresenta um PCI compreendido entre 17 e 20 MJ/kg; o teor em cloro está compreendido entre 0,2 e 0,8% Conclui-se que neste processo o parâmetro mais difícil de controlar é o teor em cloro no CDR, pois existe uma grande diversidade de resíduos com grandes quantidades de cloro na sua constituição e que por muitas vezes são difíceis de identificar e/ou separar na primeira fase do tratamento dos resíduos. Da análise ciclo de vida efetuada à produção de CDR pode-se afirmar que esta operação de gestão de resíduos apresenta uma mais-valia quando comparada com a deposição dos resíduos em aterro, não sendo a diferença entre destinos tão significativa quanto o esperado. Desta avaliação pode concluir-se que a instalação operou muito abaixo da sua capacidade, sendo esta considerada uma das melhores linhas de produção de CDR a nível nacional.

MSW: from pollution/degradation source to resource

Municipal Solid Waste is one of the biggest challenges that cities are facing: MSW is considered of the main sources of energy consumption, urban degradation and pollution. This paper defines the major negative effects of MSW on cities and proposes new solutions to guide waste policies. Most contemporary waste management efforts are focused at regional government level and based on high tech waste disposal by methods such as landfill and incineration. However, these methods are becoming increasingly expensive, energy inefficient and pollutant: waste disposal is not sustainable and will have negative implications for future generations. In this paper are proposed all the principle solutions that could be undertaken. New policy instruments are presented updating and adapting policies and encouraging innovation for less wasteful systems. Waste management plans are fundamental to increase the ability of urban areas effectively to adapt to waste challenges. These plans have to give an outline of waste streams and treatment options and provide a scenario for the following years that significantly reduce landfills and incinerators in favor of prevention, reuse and recycling. The key aim of an urban waste management plan is to set out the work towards a zero waste economy as part of the transition to a sustainable economy. Other questions remain still opened: How to change people’s behavior? What is the role of environmental education and risk perception? It is sure that the involvement of the various stakeholders and the wider public in the planning process should aim at ensuring acceptance of the waste policy.

Expertise and forms of knowledge in the government of families

This paper examines the relationship between the state and the individual in relation to an aspect of mundane family life – the feeding of babies and young children. The nutritional status of children has long been a matter of national concern and infant feeding is an aspect of family life that has been subjected to substantial state intervention. It exemplifies the imposition upon women the ‘biologico-moral responsibility’ for the welfare of children (Foucault 1991b). The state’s attempts to influence mothers’ feeding practices operate largely through education and persuasion. Through an elaborate state-sponsored apparatus, a strongly medicalised expert discourse is disseminated to mothers. This discourse warns mothers of the risks of certain feeding practices and the benefits of others. It constrains mothers through a series of ‘quiet coercions’ (Foucault 1991c) which seek to render them self-regulating subjects. Using data from a longitudinal interview study, this paper explores how mothers who are made responsible in these medical discourses around child nutrition, engage with, resist and refuse expert advice. It examines, in particular, the rhetorical strategies which mothers use to defend themselves against the charges of maternal irresponsibility that arise when their practices do not conform to expert medical recommendations.

An Ethics of Refusal: Sympathy, Intimacy and Fidelity in British Romanticism

Despite a current emphasis in Romantic scholarship on intersubjectivity, this study suggests that we still have much to learn about how theories of intersubjectivity operate in Romantic-era writings that focus on the family—the most common vehicle for exploring relationships during the period. By investigating how sympathy, intimacy, and fidelity are treated in the works of Mary Hays, Felicia Hemans, and Mary Shelley, this dissertation discovers the presence of an “ethics of refusal” within women’s Romantic-era texts. Texts that promote an ethics of refusal, I argue, almost advocate for a particular mode of relating within a given model of the family as the key to more equitable social relations, but, then, they ultimately refuse to support any particular model. Although drawn towards models of relating that, at first, seem to offer explicit pathways towards a more ethical society, texts that promote an ethics of refusal ultimately reject any program of reform. Such rejection is not unaccountable, but stems from anxieties about appearing to dictate what is best for others when others are, in reality, other than the self. In this dissertation, I draw from feminist literary critiques that focus on ethics; genre-focused literary critiques; and studies of sympathy, intimacy, and fidelity that investigate modes of relating within the context of literary works and reader-textual relations. Psychoanalytic theory also plays an important role within my third chapter on Mary Shelley’s novel Falkner. Scholarship that investigates the dialectical nature of Romantic-era literature informs my entire project. Through theorizing and studying an ethics of refusal, we can more fully understand how intersubjective modes functioned in Romantic literature and discover a Romanticism uniquely committed to attempting to turn dialectical reasoning into a social practice.

Racialized Others in Frankenstein and Wuthering Heights

In my thesis I analyze two classic English novels, Emily Brontë’s Wuthering Heights and Mary Shelley’s Frankenstein from a postcolonial perspective. I focus on the two central characters in the novels, Heathcliff and Frankenstein’s monster, who are both outsiders and markedly racialized agents in the narratives. Using Edward Said’s theory on Orientalism and Anne McClintock’s theory on imperialism and domesticity, I argue that the Monster and Heathcliff represent European anxieties concerning various issues linked with imperial expansion and identity politics. The Monster and Heathcliff are both disruptive forces in the narratives and they ultimately reveal the problematic nature of colonial attitudes which also reflect domestic power structures of gender and class. Ultimately the Monster and Heathcliff are ambiguous characters who refuse to occupy any specific role in the narrative and remain as undefined and ambivalent figures in the story.
