The love of a sage or the command of a superior: The natural law doctrines of Leibniz and Pufendorf

The study of natural law theories is presently one of the most fruitful areas of research in the studies of early modern intellectual history, and moral and political theory. Likewise the historical significance of the Enlightenment for the development of modernisation' in many different forms continues to be the subject of controversy. This collection therefore offers a timely opportunity to re-examine both the coherence of the concept of an early Enlightenment', and the specific contribution of natural law theories to its formation. The works of major thinkers such as Grotius, Hobbes, Locke, Malebranche, Pufendorf and Thomasius are reassessed, and the appeal and importance of the discourse of natural jurisprudence both to those working inside conventional educational and political structures and to those outside - such as in the Huguenot diaspora - is evaluated. This volume will therefore be of importance to all those readers concerned to study the character of the debates in the period 1650-1750 surrounding moral and political agency, sovereignty and obligation, and the legitimation of religious toleration in the divergent states and patriotic contexts of Europe.

Fed State Protein Turnover in Healthy Older Persons under a Usual Protein-Rich Diet

The objective of this study was to verify the protein turnover rates of healthy older persons under a usual protein-rich diet and to compare values to those described in the literature. This cross-sectional study was conducted at Metabolism Unit, Univ. Hospital of the School of Medicine of Ribeirao Preto, Univ. of Sao Paulo, Brazil. In this study, 7 healthy older persons aged 65.4 +/- 2.8 y, with BMI 22.7 +/- 2.4 kg/m(2) and a mean daily protein intake of 1.34 g of protein/kg were studied. A 9-h whole-body (15)N-glycine single-dose study was performed after an overnight fast. During the study, each subject received 6 isoenergetic, isonitrogenous meals at 2-h intervals based on their average intake. Ammonium, urea, and total nitrogen were quantified and analyzed by mass spectrometry, with the determination of total protein turnover rates by the (15)N-glycine method. The results show that total nitrogen output was 3.2 +/- 0.96 g/N and intake 7.7 +/- 1 g/N, (15)N nitrogen flux was 30.6 +/- 6.3 g/9 h. Endogenous nitrogen balance was positive (4.5g +/- g/N in 9 h). In conclusion, the protein turnover of healthy older persons under a usual protein-rich diet is positive during the fed state and has synthesis and degradation rates similar to those previously described in studies involving diet adaptation periods.

Differentially expressed genes in eutopic and ectopic endometrium of women with endometriosis

Objective: To elucidate the potential mechanisms involved in the physiopathology of endometriosis. We analyzed the differential gene expression profiles of eutopic and ectopic tissues from women with endometriosis. Design: Prospective laboratory study. Setting: University hospital. Patient(s): Seventeen patients in whom endometriosis was diagnosed and 11 healthy fertile women. Intervention(s): Endometrial biopsy specimens from the endometrium of healthy women without endometriosis and from the eutopic and ectopic endometrium tissues of patients with endometriosis were obtained in the early proliferative phase of the menstrual cycle. Main Outcome Measure(s): Six paired samples of eutopic and ectopic tissue were analyzed by subtractive hybridization. To evaluate the expression of genes found by rapid subtraction hybridization methods, we measured CTGF, SPARC, MYC, MMP and IGFBP1 genes by real-time polymerase chain reaction in all samples. Result(s): This study identified 291 deregulated genes in the endometriotic lesions. Significant expression differences were obtained for SPARC, MYC, and IGFBP1 in the peritoneal lesions and for MMP3 in the ovarian endometriomas. Additionally, significant differences were obtained for SPARC and IGFBP1 between the peritoneal and ovarian lesions. No significant differences were found for the studied genes between the control and the eutopic endometrium. Conclusion(s): This study identified 291 genes with differential expression in endometriotic lesions. The deregulation of the SPARC, MYC, MMP3, and IGFBP1 genes may be responsible for the loss of cellular homeostasis in endometriotic lesions. (Fertil Steril(R) 2010;93:1750-73.

Microbial and sensory changes throughout the ripening of Prato cheese made from milk with different levels of somatic cells

The objective of this research was to evaluate the effects of 2 levels of raw milk somatic cell count (SCC) on the composition of Prato cheese and on the microbiological and sensory changes of Prato cheese throughout ripening. Two groups of dairy cows were selected to obtain low-SCC (<200,000 cells/mL) and high-SCC (>700,000 cells/mL) milks, which were used to manufacture 2 vats of cheese. The pasteurized milk was evaluated according to the pH, total solids, fat, total protein, lactose, standard plate count, coliforms at 45 degrees C, and Salmonella spp. The cheese composition was evaluated 2 d after manufacture. Lactic acid bacteria, psychrotrophic bacteria, and yeast and mold counts were carried out after 3, 9, 16, 32, and 51 d of storage. Salmonella spp., Listeria monocytogenes, and coagulase-positive Staphylococcus counts were carried out after 3, 32, and 51 d of storage. A 2 x 5 factorial design with 4 replications was performed. Sensory evaluation of the cheeses from low- and high-SCC milks was carried out for overall acceptance by using a 9-point hedonic scale after 8, 22, 35, 50, and 63 d of storage. The somatic cell levels used did not affect the total protein and salt: moisture contents of the cheeses. The pH and moisture content were higher and the clotting time was longer for cheeses from high-SCC milk. Both cheeses presented the absence of Salmonella spp. and L. monocytogenes, and the coagulase-positive Staphylococcus count was below 1 x 10(2) cfu/g throughout the storage time. The lactic acid bacteria count decreased significantly during the storage time for the cheeses from both low- and high-SCC milks, but at a faster rate for the cheese from high-SCC milk. Cheeses from high-SCC milk presented lower psychrotrophic bacteria counts and higher yeast and mold counts than cheeses from low- SCC milk. Cheeses from low- SCC milk showed better overall acceptance by the consumers. The lower overall acceptance of the cheeses from high-SCC milk may be associated with texture and flavor defects, probably caused by the higher proteolysis of these cheeses.

Can the durability of one-step self-etch adhesives be improved by double application or by an extra layer of hydrophobic resin?

Objectives: This study evaluated the immediate and 6-month resin-dentin mu-bond strength (mu TBS) of one-step self-etch systems (Adper Prompt L-Pop [AD] 3M ESPE; Xeno III [XE] Dentsply De Trey; iBond [iB] Heraeus Kulzer) under different application modes. Materials and methods: Dentin oclusal surfaces were exposed by grinding with 600-grit SiC paper. The adhesives were applied according to the manufacturer`s directions [MD], or with double application of the adhesive layer [DA] or following the manufacturer`s directions plus a hydrophobic resin layer coating [HL]. After applying the adhesive resins, composite crowns were built up incrementally. After 24-h water storage, the specimens were serially sectioned in ""x"" and ""y"" directions to obtain bonded sticks of about 0.8 mm 2 to be tested immediately [IM] or after 6 months of water storage [6M] at a crosshead speed of 0.5 mm/min. The data from each adhesive was analyzed by a two-way repeated measures ANOVA (mode of application vs. storage time) and Tukey`s test (alpha = 0.05). Results: The adhesives performed differently according to the application mode. The DA and HL either improved the immediate performance of the adhesive or did not differ from the MD. The resin-dentin bond strength values observed after 6 months were higher when a hydrophobic resin coat was used than compared to those values observed under the manufacturer`s directions. Conclusions: The double application of one-step self-etch system can be safety performed however the application of an additional hydrophobic resin layer can improve the immediate resin-dentin bonds and reduce the degradation of resin bonds over time.

Phenotypic and genetic analyses of a short measure of psychosis-proneness in a large-scale Australian twin study

Previous genetic analyses of psychosis proneness have been limited by their small sample size. For the purposes of large-scale screening, a 12-item questionnaire was developed through a two-stage process of reduction from the full Chapman and Chapman scales. 3685 individuals (including 1438 complete twin pairs) aged 18–25 years and enrolled in the volunteer Australian Twin Registry returned a mail questionnaire which included this psychosis proneness scale and the Eysenck Personality Questionnaire. Despite the brevity of the questionnaire, item and factor analysis identified four unambiguous and essentially uncorrelated scales. There were (1) Perceptual Aberration – Magical Ideation; (2) Hypomania – Impulsivity/Nonconformity; (3) Social Anhedonia and (4) Physical Anhedonia. Model-fitting analyses showed additive genetic and specific environmental factors were sufficient for three of the four scales, with the Social Anhedonia scale requiring also a parameter for genetic dominance. There was no evidence for the previously hypothesised sex differences in the genetic determination of psychosis-proneness. The potential value of multivariate genetic analysis to examine the relationship between these four scales and dimensions of personality is discussed. The growing body of longitudinal evidence on psychosis-proneness suggests the value of incorporating this brief measure into developmental twin studies.

Rice Culture of Divine Right

O texto pretende localizar os ritmos do comércio de Bengala durante as oito hegemonias sucessivas que dominaram a Ásia meridional e a Ásia do Sudeste entre 2000 BC e 1750 AD. Estas foram: 1) A transição inicial de tribalismo para Estados sob a orientação do Bramanismo; 2) Budismo; 3) Revivalismo brâmane (purânico) nos séculos IX e X; 4) A revolução comercial no Golfo de Bengala no século XI; 5) A ordem mongol; 6) A primeira rede islâmica; 7) O sistema-mundo europeu do tipo português; 8) O sistema de Estados no século XVI – um segundo sistema-mundo islâmico. O texto sugere que Bengala manifestou fortes potencialidades comerciais nas fases 2,4 e 6. Esta força ficou reduzida no século XVI devido a uma combinação de factores: As ligações com o ocidente desde o período de Husain Shahi e continuadas nos tempos dos Mongóis, as ligações riverinas oesteleste dos séculos XVI –XVIII, o declínio do comércio oriental, a retirada chinesa, a queda do Aração e o declínio do comércio português no Golfo de Bengala.

A "civilização dos índios" no século XVIII: da legislação pombalina ao "Plano" de Domingos Barreto

Este artigo analisa o surgimento da ideia de "civilização dos índios" no contexto da política colonial lusitana para os povos indígenas do Brasil, na segunda metade do século XVIII, com ênfase na legislação pombalina, e o "Plano sobre a civilização dos índios do Brasil", de Domingos Barreto. A documentação analisada sugere que o ideal de "civilização dos índios" difundido a partir da década de 1750 contrapunha-se ao sistema de catequese seguido pelos jesuítas e outros religiosos desde o século XVI, visando diminuir o papel da Igreja e das ordens religiosas na sociedade colonial e promover a equiparação dos índios aos demais vassalos do reino.

Modificação de estruturas zeolíticas por dessilicação: caracterização da porosidade e da acidez por técnicas de adsorção e catálise

Este trabalho experimental teve como objectivo a dessilicação dos zeólitos MOR, BEA, MFI e FER de acordo com condições experimentais descritas na literatura e ainda a optimização das condições de dessilicação para o zeólito MOR, onde se variaram os parâmetros: temperatura, tempo e concentração de solução de NaOH. As amostras foram caracterizadas recorrendo a técnicas de caracterização estrutural, morfológica, textural e de acidez, nomeadamente difracção de raios X, microscopia electrónica de varrimento, adsorção de azoto a baixa temperatura, espectroscopia de infravermelho, “cracking” do n-heptano e adsorção de piridina seguida de espectroscopia de infravermelho. Nas estruturas dessilicadas, de acordo com a literatura registaram-se diferenças relativamente aos resultados publicados, o que pode dever-se às diferentes características dos materiais estudados, nomedamente a razão Si/Al e o tamanho dos cristais. Verificou-se assim que o desenvolvimento de mesoporosidade é fortemente influenciado pelas propriedades dos materiais de partida. No estudo de optimização das condições de dessilicação para a estrutura MOR, verificou-se que a amostra que conduziu a melhores resultados de propriedades texturais, estruturais, morfológicas e de acidez foi a amostra sujeita a tratamento alcalino com uma solução de NaOH com uma concentração de 0,2 M, à temperatura de 85 ºC durante 2 horas. O tratamento alcalino resultou no desenvolvimento de mesoporosidade, evidenciado pelo aumento de número de moles adsorvidas a pressões relativas elevadas e também devido à presença de uma forma de histerese do tipo H4. A extracção de sílicio da rede do zeólito através do tratamento alcalino foi alcançado. Este facto pode ser comprovado através da análise dos espectros de infravermelho, concretamente através da análise da região correspondente às bandas estruturais, verificando-se um desvio de banda correspondente ao estiramento assimétrico das ligações T-O-T, sensivelmente a 1090 cm-1, para valores menores. Por fim, procedeu-se à realização do tratamento alcalino com recurso à radiação microondas, tendo-se obtido resultados idênticos aos de algumas amostras cuja dessilicação foi realizada convencionalmente, mas num tempo de tratamento inferior.

Motivations in volunteer work

The objective of this paper is to review and discuss the literature about volunteers’ motivations to donate their time to NGOs (Non Governmental Organisations). According to Parboteeah, Cullenb & Lim (2004) management research has not paid much attention to voluntarism, however, voluntarism is a substantial part of productive work for many societies. Wilson & Pimm (1996) show that in Great Britain about 39% of the adult population has been involved in some volunteer activity for some period of time. In the U.S.A. these values reach 50% (Wilson & Pimm, 1996). Considering the benefits that voluntarism can bring to an organisation, we understand that more attention must be devoted to this phenomenon. The more an organisation knows volunteers, the better this organisation will be able to meet the needs and expectations of these individuals. We present a literature review that illustrates and compares the different motivations associated with volunteer work. The paper includes a bibliographical databases search in specialised journals. The search used the key words “motivations” and “voluntarism” (in the heading and text body) and covered all numbers between 2000 and 2007. We identify the existence of repeated motivations (Holmberg & Söderlung, 2005; Prouteau & Wolff, 2008; Soupourmas & Ironmonger, 2001; Yavas & Riecken, 1997), which allow the establishment of a typology of volunteers’ motivations, based on four categories: altruism, social needs, self-esteem, learning and self-development. Finally we identify three main gaps in the literature that justify further research. First, research focusing on the differences between motivations related to volunteers’ "Attraction" versus "Retention" in NGO’s is nil. Second, the great majority of the studies rely on north American (USA and Canada) and Australian context, which demands for further research in European countries. Third, the majority of NGOs researched are related to sport, art or the environment, and it would be interesting to explore the relationship between motivation and NGO type. These questions may obtain interesting answers for NGO management, in particular with regard to volunteer attraction and retention.

Alcipe, Nathercia e Tirse: Considerações sobre as luzes no feminino no Portugal de setecentos

O presente artigo desenvolve-se em torno de três damas esclarecidas da sociedade portuguesa de setecentos: D. Leonor de Almeida (1750-1839), ou Alcipe; D. Catarina de Lencastre (1749-1824), ou Nathercia; e D. Teresa de Mello Breyner (1739-1798?), ou Tirse. Sabendo que o século XVIII foi um período marcado por mudança e controvérsia, pela emergência de novos paradigmas, pelo reequacionamento de estruturas mentais e tradições seculares – ainda que em Portugal se experimentasse uma certa resistência às teorias filosóficas emergentes – a questão que lançamos e procuramos analisar é: qual o reflexo destas transformações no universo feminino? Assim, partindo dos três exemplos referidos e a eles tornando, pretendemos problematizar três questões centrais no discurso iluminista – educação, leituras e viagens – observando como estas matérias, assaz discutidas e teorizadas ao longo do século XVIII, se repercutiram na formação feminina em solo português e, por outro lado, analisar o modesto mas expressivo papel que as referidas damas assumiram na propagação da cultura das luzes em Portugal.

Avaliação do impacto energético resultante da utilização de repetidores em sistema LTE

Actualmente uma grande preocupação global refere-se ao continuo aumento do custo da energia, resultante da procura e do impacto ambiental. A escalada do custo da energia obriga a procura sistemática de melhores sistemas que permitam diminuir esse custo. Nas comunicações móveis sem fios a economia de energia obtida pelo aumento da eficiência do equipamento das estaçõesbase é insuficiente, pelo qual é necessário também encontrar soluções ao nível da arquitectura. O LTE define os repetidores como um recurso de baixo consumo para aumentar a cobertura e ou capacidade da rede. Nesta dissertação é avaliado um método de economia de energia baseado na substituição de uma estação-base central, circundada por outras estações-base, por um determinado número de repetidores. A cobertura e a capacidade resultante é avaliada assim como a energia poupada. Os resultados obtidos permitem verificar que se pode poupar até 1 000,00 € anuais e 20 kW diários com a substituição de uma estação-base, completamente rodeada por outras estações, por um número de repetidores compreendido entre 1 e 9 dependendo da ISD (até 1750 m). Verifica-se ainda um ganho de eficiência energética de até 13% ao nível do sistema.
