Fabrication of macro–mesoporous titania/alumina core–shell materials in oil/water interface

A series of macro–mesoporous TiO2/Al2O3 nanocomposites with different morphologies were synthesized. The materials were calcined at 723 K and were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Transmission electron microscope (TEM), N2 adsorption/desorption, Infrared Emission Spectroscopy (IES), X-ray photoelectron spectroscopy (XPS) and UV–visible spectroscopy (UV–visible). A modified approach was proposed for the synthesis of 1D (fibrous) nanocomposite with higher Ti/Al molar ratio (2:1) at lower temperature (<100 °C), which makes it possible to synthesize such materials on industrial scale. The performance–morphology relationship of as-synthesized TiO2/Al2O3 nanocomposites was investigated by the photocatalytic degradation of a model organic pollutant under UV irradiation. The samples with 1D (fibrous) morphology exhibited superior catalytic performance than the samples without, such as titania microspheres.

A theoretical framework for designing and evaluating strategies to identify cases of serious child abuse and neglect

A central dimension of the State’s responsibility in a liberal democracy and any just society is the protection of individuals’ central rights and freedoms, and the creation of the minimum conditions under which each individual has an opportunity to lead a life of sufficient equality, dignity and value. A special subset of this responsibility is to protect those who are unable to protect themselves from genuine harm. Substantial numbers of children suffer serious physical, emotional and sexual abuse, and neglect at the hands of their parents and caregivers or by other known parties. Child abuse and neglect occurs in a situation of extreme power asymmetry. The physical, social, behavioural and economic costs to the individual, and the social and economic costs to communities, are vast. Children are not generally able to protect themselves from serious abuse and neglect. This enlivens both the State’s responsibility to protect the child, and the debate about how that responsibility can and should be discharged. A core question arises for all societies, given that most serious child maltreatment occurs in the family sphere, is unlikely to be disclosed, causes substantial harm to both individual and community, and infringes fundamental individual rights and freedoms. The question is: how can society identify these situations so that the maltreatment can be interrupted, the child’s needs for security and safety, and health and other rehabilitation can be met, and the family’s needs can be addressed to reduce the likelihood of recurrence? This chapter proposes a theoretical framework applicable for any society that is considering justifiable and effective policy approaches to identify and respond to cases of serious child abuse and neglect. The core of the theoretical framework is based on major principles from both classical liberal political philosophy (Locke and Mill), and leading political philosophers from the twentieth century and the first part of the new millennium (Rawls, Rorty, Okin, Nussbaum), and is further situated within fundamental frameworks of civil and criminal law, and health and economics.

Transdisciplinary synthesis for ecosystem science, policy and management: The Australian experience

Mitigating the environmental effects of global population growth, climatic change and increasing socio-ecological complexity is a daunting challenge. To tackle this requires synthesis: the integration of disparate information to generate novel insights from heterogeneous, complex situations where there are diverse perspectives. Since 1995, a structured approach to inter-, multi- and trans-disciplinary1 collaboration around big science questions has been supported through synthesis centres around the world. These centres are finding an expanding role due to ever-accumulating data and the need for more and better opportunities to develop transdisciplinary and holistic approaches to solve real-world problems. The Australian Centre for Ecological Analysis and Synthesis (ACEAS ) has been the pioneering ecosystem science synthesis centre in the Southern Hemisphere. Such centres provide analysis and synthesis opportunities for time-pressed scientists, policy-makers and managers. They provide the scientific and organisational environs for virtual and face-to-face engagement, impetus for integration, data and methodological support, and innovative ways to deliver synthesis products. We detail the contribution, role and value of synthesis using ACEAS to exemplify the capacity for synthesis centres to facilitate trans-organisational, transdisciplinary synthesis. We compare ACEAS to other international synthesis centres, and describe how it facilitated project teams and its objective of linking natural resource science to policy to management. Scientists and managers were brought together to actively collaborate in multi-institutional, cross-sectoral and transdisciplinary research on contemporary ecological problems. The teams analysed, integrated and synthesised existing data to co-develop solution-oriented publications and management recommendations that might otherwise not have been produced. We identify key outcomes of some ACEAS working groups which used synthesis to tackle important ecosystem challenges. We also examine the barriers and enablers to synthesis, so that risks can be minimised and successful outcomes maximised. We argue that synthesis centres have a crucial role in developing, communicating and using synthetic transdisciplinary research.

In Perpetual Motion: Theories of Power, Educational History, and the Child

"In Perpetual Motion is an "historical choreography" of power, pedagogy, and the child from the 1600s to the early 1900s. It breaks new ground by historicizing the analytics of power and motion that have interpenetrated renditions of the young. Through a detailed examination of the works of John Locke, Jean-Jacques Rousseau, Johann Herbart, and G. Stanley Hall, this book maps the discursive shifts through which the child was given a unique nature, inscribed in relation to reason, imbued with an effectible interiority, and subjected to theories of power and motion. The book illustrates how developmentalist visions took hold in U.S. public school debates. It documents how particular theories of power became submerged and taken for granted as essences inside the human subject. In Perpetual Motion studiously challenges views of power as in or of the gaze, tracing how different analytics of power have been used to theorize what gazing could notice."--BOOK JACKET.

(Ap)pointing the canon Rousseau's Émile, visions of the state, and education

Jean-Jacques Rousseau’s Émile, ou de I’Education (Émile, or on Education) has been described by Rousseau scholars in latter twentieth century English-language philosophy as an educational classic. In 1995 Robert Wokler argued that together with Montesquieu, Hume, Smith, and Kant among his contemporaries, Rousseau had exerted the most profound influence on modern European intellectual history, “perhaps even surpassing anyone else of his day." For Wokler Émile is “the most significant work on education after Plato’s Republic.” Earlier in 1977, Allan Bloom questioned why Émile had not been the subject of analysis in philosophy relative to the rest of Rousseau‘s work, for “Émile is truly a great book, one that lays out for the first time and with the greatest clarity and vitality the modern way of posing the problems of psychology.” Bloom also saw Émile as “one of those rare total or synoptic books... a book comparable to Plato’s Republic, which it is meant to rival or supersede” and argued that Rousseau himself was at the source of a new tradition: “Whatever else Rousseau may have accomplished, he presented alternatives available to man more comprehensively and profoundly and articulated them in the form which has dominated discussion since his time." Even Peter Gay’s earlier commentary on John Locke and education in 1964 could not escape this central positioning of the text. The significance of Locke’s Some Thoughts on Education is weighed in relation to its impact on Rousseau‘s Émile. For Gay, the latter is “probably the most influential revolutionary tract on education that we have.”

New genetic loci link adipose and insulin biology to body fat distribution

Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10−8). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms.

Genetic studies of body mass index yield new insights for obesity biology

Obesity is heritable and predisposes to many diseases. To understand the genetic basis of obesity better, here we conduct a genome-wide association study and Metabochip meta-analysis of body mass index (BMI), a measure commonly used to define obesity and assess adiposity, in up to 339,224 individuals. This analysis identifies 97 BMI-associated loci (P < 5 × 10−8), 56 of which are novel. Five loci demonstrate clear evidence of several independent association signals, and many loci have significant effects on other metabolic phenotypes. The 97 loci account for ~2.7% of BMI variation, and genome-wide estimates suggest that common variation accounts for >20% of BMI variation. Pathway analyses provide strong support for a role of the central nervous system in obesity susceptibility and implicate new genes and pathways, including those related to synaptic function, glutamate signalling, insulin secretion/action, energy metabolism, lipid biology and adipogenesis.

Defining the role of common variation in the genomic and biological architecture of adult human height

Using genome-wide data from 253,288 individuals, we identified 697 variants at genome-wide significance that together explained one-fifth of the heritability for adult height. By testing different numbers of variants in independent studies, we show that the most strongly associated approximately 2,000, approximately 3,700 and approximately 9,500 SNPs explained approximately 21%, approximately 24% and approximately 29% of phenotypic variance. Furthermore, all common variants together captured 60% of heritability. The 697 variants clustered in 423 loci were enriched for genes, pathways and tissue types known to be involved in growth and together implicated genes and pathways not highlighted in earlier efforts, such as signaling by fibroblast growth factors, WNT/beta-catenin and chondroitin sulfate-related genes. We identified several genes and pathways not previously connected with human skeletal growth, including mTOR, osteoglycin and binding of hyaluronic acid. Our results indicate a genetic architecture for human height that is characterized by a very large but finite number (thousands) of causal variants.

Overparenting and homework: The student’s task, but everyone’s responsibility

A high level of parental involvement is widely considered to be essential for optimal child and adolescent development and wellbeing, including academic success. However, recent consideration has been given to the idea that extremely high levels of parental involvement (often called ‘overparenting’ or ‘helicopter parenting’) might not be beneficial. This study used a newly created overparenting measure, the Locke Parenting Scale (LPS), to investigate the association of overparenting and children’s homework. Eight hundred and sixty-six parents completed online questionnaires about their parenting beliefs and intentions, and their attitudes associated with their child’s homework. Parents with higher LPS scores tended to take more personal responsibility for the completion of their child’s homework than did other parents, and ascribed greater responsibility for homework completion to their child’s teacher. However, increased perceived responsibility by parents and teachers was not accompanied by a commensurate reduction in what they perceived was the child’s responsibility. Future research should examine whether extreme parental attitudes and reported behaviours translate to validated changes in actual homework support.

Ennaltamäärätty kääntymys: Predestinaatio ja vapaan tahdon ongelma Jonathan Edwardsin teologiassa

Tämän tutkielman tehtävänä on ollut selvittää onko ihmisellä vapaata tahtoa Jonathan Edwardsin mukaan. Lähteenäni minulla on ollut Edwardsin Freedom of the Will -teos sekä Miscellaneous- sarjasta Concerning the Divine Degrees -kirjoitus. Metodina minulla on ollut systemaattinen analyysi. Edwardsin taustana oli puritanismi. Esimerkiksi sakramenteilla ei ollut puritanismin piirissä samaa ratkaisevaa merkitystä uskon synnyttäjänä ja ylläpitäjänä kuin perinteisissä kristillisissä kirkoissa oli ollut. Puritanistien keskeinen armonväline oli saarna. Saarnalla pyrittiin vaikuttamaan ihmisen tahtoon antamalla rationaalisia perusteita Raamatun pelastustapahtumasta. Tämä on nähtävissä myös Jonathan Edwardsin teologiassa. Deismi ja valistus vaikuttivat myös Edwardsin aikaiseen ajatteluun voimakkaasti. Edwardsin Berkeleytä muistuttava idealismi kuitenkin takasi sen, että Jumala ei irronnut maailmasta vaan oli kaikessa koko ajan läsnä. Erityisesti Locke Newtonin luonnontieteiden filosofina vaikutti Edwardsin filosofiseen ajatteluun tahdon vapaus -kysymyksen osalta. Edwards pyrki Locken ja Newtonin avulla puolustamaan perinteistä kalvinistista kristillisyyttä. Tämän kilpailijaksi puritanismin piirissä oli tullut ajan henkeen sopiva järkiperäinen arminiolaisuus, joka edusti myös anti-revivalismia. Tähän arminiolaisuuteen liittyi perinteisistä kristillisistä opeista luopuminen. Tämä arminiolaisuus oli kehittynyt antropologisempaan suuntaan Remonstranssin ajoista korostaen ihmisen vapaita tahdon akteja. Näin ihminen pystyi päättämään uskoiko hän vai ei. Edwardsille usko ja pelastuminen perustuivat Jumalan valintaan, jossa kolmiyhteinen Jumala otti ihmisen yhteyteensä. Tämä kääntymys ilmeni kommuuniona ja uniona Kristuksen kanssa. Edwardsin ajattelua tahdon vapauden osalta avaa kompatibilismi. Kompatibilismin mukaan ennaltamäärääminen ei ole ristiriidassa vapaan tahdon kanssa, vaan päinvastoin sen lähtökohta ja perusta. Kääntymissä olemme eri näkökulmista täysin passivisia ja täysin aktiivisia. Kompatibilismin myötä Edwardsin kirjoitusten pohjalta pystytään johtamaan ennalta määrätty uskonratkaisu. Myöhemmin Edwardsin seuraajat New Lights harppasivat ironisesti arminiolaiseen suuntaan korostaen juuri uskonratkaisua. Vaikka Jumalalla on sanan varsinaisessa merkityksessä vapaa tahto, niin silti Hän toimii välttämättä pyhästi. Samoin Jeesus Kristus on linkkinä ihmisten välttämättömälle, mutta vastuulliselle toiminnalle. Jeesuksen valinta on kaikkien pyhien valinnan perusta. Ne, jotka Jumala hylkää helvettiin saavat oikeudenmukaisen rangaistuksen, koska Jumala rankaisee heissä itsessään olevaa pahaa. Se, miksi Jumala valitsee toiset ja hylkää toiset, kuuluu Jumalan salattuun tahtoon. Jumalan ilmoitetun tahdon mukaan Hän tahtoo kaikkien pelastuvan. Arminiolaiset hylkäävät ennaltamääräämisen, mutta hyväksyvät ennalta tietämisen. Edwardsille nämä ovat sama asia. Edwardsin mukaan välttämättömyys ei ole ristiriidassa vapauden kanssa. Luonnollisella ja moraalisella välttämättömyydellä on yhteys. Arkikielessä moraalista välttämättömyyttä ei oleteta. Koko tahdon vapaus -kysymys on pitkälti kielellinen. Arkikielessä ja filosofisessa kielessä on ero. Tahto ei ole agentti, joka voi valita itsenäisesti. Vapaus on ihmisen, ei tahdon ominaisuus. Siksi kysymys tahdon vapaudesta tulisi esittää onko ihminen vapaa. Edwards ja arminiolaiset ymmärtävät vapauden eri tavoin. Edwardsin mukaan tahdolla on oltava alku, eikä tahto voi koskaan arminiolaisten tavoin neutraali. Arminiolaiset hylkäävät perisyntiopin klassisessa merkityksessä, mistä seuraa erilainen lähtökohta. Sellaisena kuin arminiolaiset esittävät vapaan tahdon, meillä ei sitä Edwardsin mukaan ole. Vaikka kaikki tapahtuu Edwardsin mukaan välttämättä, niin silti olemme vastuullisia moraalisia agentteja.

El problema del innatismo en Antonio Rosmini : (parte II)

Resumen: Esta parte del artículo repasa las principales teorías modernas sobre el innatismo, analizando sus puntos fuertes y débiles a partir de la teoría rosminiana de la presencia innata de la idea de ser. Se subraya la simplicidad de esta teoría, lo que le confiere un elevado carácter explicativo, en contraste con los dificultades que suscitan las filosofías de Descartes, Locke, Leibniz, Malebranche y Kant.

La teoría aristotélica de la abstracción y su olvido moderno

Resumen: Este estudio analiza la teoría aristotélica de la abstracción, tratando de rescatar su sentido originario a partir de los textos del autor, así como los aportes de los aristotélicos medievales más relevantes, especialmente Tomás de Aquino. Y luego se pasa a describir algunos hitos fundamentales de la evolución posterior de dicha teoría en la historia de la Filosofía, como son: 1) La contraposición entre abstracción e intuición en Duns Escoto y Guillermo de Ockham. 2) el intuicionismo de Descartes 3) La reinterpretación empirista de la abstracción en J. Locke 4) La ausencia de la abstracción en el Espinoza, Leibniz y Kant, así como su sustitución por la “aufhebung” en Hegel. 5) La peculiar aproximación husserliana a la abstracción a partir de su método fenomenológico y 6) la relación de la teoría de la abstracción con el pensamiento de algunos autores contemporáneos como Zubiri, Polo y, especialmente, Heidegger.

Fundação do PMDB e PT no Distrito Federal: redemocratização e formação dos diretórios

Analisa o processo de organização dos diretórios regionais do Partido do Movimento Democrático Brasileiro (PMDB) e do Partido dos Trabalhadores (PT) no Distrito Federal (DF). Analisa também o movimento pela autonomia política do DF e inclui pesquisa com filiados para levantar informações de caráter socioeconômico e político. As pesquisas documentais, consultas à literatura e entrevistas demonstram que a atividade político-partidária ocorreu no DF, apesar das proibições vigentes ao longo da década de 1970 até meados da década de 1980. Inicialmente, as atividades eram realizadas sob a coordenação de entidades de caráter suprapartidário. O trabalho apresenta ainda a evolução histórica do pensamento político e do conceito de democracia. Desde Sócrates, Platão e Aristóteles até luminares da teoria política, como Maquiavel, Hobbes, Locke, Montesquieu e Rousseau. Um relato histórico mostra também como surgiram as primeiras agremiações partidárias em países como a Inglaterra, França, Alemanha e Itália e também nos Estados Unidos. Outra parte apresenta a evolução da vida partidária no Brasil ao longo dos anos.

Senso comum e filosofia

Verifica-se, no correr da história da filosofia, dois sentidos próximos, mas divergentes, no emprego da expressão senso comum. Propõe-se a designação de senso comum natural para um e a de senso comum cultural para o outro, designações estas que unificam razoavelmente, dentro de suas próprias vertentes, os conceitos de senso comum e às quais corresponde algo de concreto, segundo definições estritas. A partir dessas definições, estuda-se o relacionamento entre a filosofia e o senso comum, procurando estabelecer até que ponto se trata de uma relação de antagonismo ou de dependência, na busca de um conhecimento que possa ser tido por verdadeiro.
