Plant genome values: How much do we know?

Plants are the basis of life on earth. We cannot overemphasize their importance. The value of plant genome initiatives is self-evident. The need is to identify priorities for action. The angiosperm genome is highly variable, but the extent of this variability is unknown. Uncertainties remain about the number of genes and the number of species living. Many plants will become extinct before they are discovered. We risk losing both genes and vital information about plant uses. There are also major gaps in our karyotypic knowledge. No chromosome count exists for >70% of angiosperm species. DNA C values are known for only ≈1% of angiosperms, a sample unrepresentative of the global flora. Researchers reported new relationships between genome size and characters of major interest for plant breeding and the environment and the need for more data. In 1997, a Royal Botanic Gardens Kew workshop identified gaps and planned international collaboration to fill them. An electronic version of the Angiosperm DNA C value database also was published. Another initiative, which will make a very significant contribution to the conservation of plant genetic diversity on a global scale is Kew’s Millennium Seed Bank, partly funded by the U.K. Millennium Commission, celebrating the year 2000. Costing up to £80 million (£1 = $1.62), its main aims are to collect and conserve the seed of almost all of the U.K. spermatophyte flora by the year 2000, to collect and conserve a further 10% of the world spermatophyte flora principally from the drylands by 2009, and to provide a world class building as the focus of this activity by 2000.

Balancing immunity and tolerance: deleting and tuning lymphocyte repertoires.

Immunological self-tolerance is ensured by eliminating or inhibiting self-reactive lymphocyte clones, creating physical or functional holes in the B- and T-lymphocyte antigen receptor repertoires. The nature and size of these gaps in our immune defenses must be balanced against the necessity of mounting rapid immune responses to an everchanging array of foreign pathogens. To achieve this balance, only a fraction of particularly hazardous self-reactive clones appears to be physically eliminated from the repertoire in a manner that fully prevents their recruitment into an antimicrobial immune response. Many self-reactive cells are retained with a variety of conditional and potentially flexible restraints: (i) their ability to be triggered by antigen is diminished by mechanisms that tune down signaling by their antigen receptors, (ii) their ability to carry out inflammatory effector functions can be inhibited, and (iii) their capacity to migrate and persist is constrained. This balance between tolerance and immunity can be shifted, altering susceptibility to autoimmune disease and to infection by genetic or environmental differences either in the way antigens are presented, in the tuning molecules that adjust triggering set points for lymphocyte responses to antigen, or in the effector molecules that eliminate, retain, or expand particular clones.

Promoção, comunicação e educação em saúde: a prática da acupuntura e da fitoterapia

Esta pesquisa discute a Comunicação em Saúde no contexto das Práticas Integrativas e Complementares (PIC) no Sistema Único de Saúde (SUS), no que concerne ao tratamento do câncer realizado num hospital público de Campinas. O arcabouço teórico se debruça sobre as diretrizes do ideário da Promoção da Saúde e sobre as discussões da Educação em Saúde, por serem premissas fundamentais para que a Comunicação em Saúde seja participativa e democrática, e que a Comunicação das PIC conquiste maior espaço na Saúde Pública. O objetivo geral foi investigar o processo de comunicação entre profissionais de saúde e usuários do SUS participantes do Projeto de Construção do Cuidado Integrativo (PCCI). A metodologia utilizada foi a qualitativa tendo como instrumentos pesquisa documental e entrevistas semi-estruturadas para a coleta dos dados. Os participantes do estudo foram usuários que fizeram parte do grupo de Acupuntura e de Fitoterapia e usaram práticas complementares ao tratamento convencional do câncer, e também os profissionais de saúde envolvidos no PCCI realizado no Hospital de Clínicas da Universidade Estadual de Campinas (UNICAMP)/SP. Os dados foram analisados por meio da análise temática de conteúdo de Bardin, que permitiu identificar as seguintes categorias: Medo da intervenção, Analgesia como resultado, Continuidade do tratamento, Falta de informação e Divulgação das práticas. Os resultados mostraram que houve dificuldades de comunicação, indicando lacunas importantes em relação à infraestrutura, à falta de divulgação e continuidade do tratamento complementar com as PIC, a falta de valorização da participação popular e estímulo à autonomia como preconiza o ideário da Promoção da Saúde. Concluiu-se que o modelo de saúde vigente, de base biomédica, não tem permitido a participação dos usuários, e, mais ainda, tem dificultado o desenvolvimento da comunicação democrática, humanizada e solidária. O Projeto (PCCI) foi importante em sua execução, uma vez que trouxe resultados positivos com o uso das PIC por melhorar as condições da qualidade de vida dos usuários e ter promovido analgesia, conferido maior disposição e recuperação dos movimentos. Entretanto, o Projeto (PCCI) não teve potencial o suficiente para provocar uma mudança na lógica do tratamento convencional que está hegemonicamente imerso no modelo biomédico, com isso limitando a inserção e a comunicação das PIC na Saúde Pública e dificultando a abertura para o diálogo entre os diferentes saberes. Entende-se que este é um dos principais desafios da Medicina Tradicional e Complementar (MTC).

Expressões emocionais de sorriso e choro na relação do bebê com seus pares, na creche

A expressão emocional é um dos meios de comunicação primordiais do bebê humano, sendo sua manifestação um recurso que lhe garante a própria sobrevivência. Esta temática tem sido bastante estudada, usualmente, na relação do bebê com adultos, mais particularmente com a mãe, em condições de laboratório e ambiente doméstico. No entanto, novas configurações sociais emergiram, em que o cuidado da criança pequena tem sido cada vez mais compartilhado com instituições de educação infantil, onde os pares de idade são os parceiros mais frequentes. A revisão da literatura relacionada à expressividade emocional entre pares de bebês evidencia lacunas nesse campo, e há autores que afirmam o não reconhecimento da ocorrência mesmo da interação, já que a interação entre coetâneos nos dois primeiros anos de vida não é vista como viável. Com isso, traçamos o objetivo de verificar se ocorrem manifestações de expressividade emocional de sorriso e choro em interações de pares de bebês, no ambiente do berçário de uma creche. E, em ocorrendo, investigar como se dão. Com embasamento teórico-metodológico na Rede de Significações, realizamos um estudo longitudinal de casos múltiplos, com análise qualitativa. Participaram da pesquisa dezoito bebês de uma creche pública localizada no interior do Estado de São Paulo, e três educadoras responsáveis pela turma. Dentre os bebês, Tiago (cinco a dez meses de idade) e Bruno (oito meses a um ano e um mês de idade) foram sujeitos focais, sendo acompanhados durante cinco meses, através de videogravações semanais de trinta minutos para cada bebê. A análise do material empírico se dividiu em duas etapas: 1) mapeamento das ocorrências de sorriso e choro, discriminando os parceiros com os quais os bebês interagiram ao se expressar; e, 2) análise qualitativa dos episódios interativos nos quais Bruno e Tiago se expressaram emocionalmente com os pares. A partir das diferentes formas de expressão do bebê, tanto com base na literatura como no material empírico analisado, foram criadas as categorias de riso, sorriso, choramingo, choro e choro prolongado. Realizada a análise, não se verificou a ocorrência de risos nas interações dos bebês, pelo menos nos dias em que foram feitas as gravações. Com relação aos sorrisos de Tiago, observamos que se manifestaram em situações lúdicas, e se modificaram ao longo do tempo. Por volta dos oito / nove meses do bebê, os sorrisos passaram a ter repercussão nos parceiros, que brevemente reagiram à expressão. No caso de Bruno, também aos nove meses ele passou a manifestar alguns sorrisos que repercutiram e contagiavam os pares de idade. Os sorrisos de Bruno se manifestaram com uma riqueza de sentidos identificáveis nas interações, não sorrindo apenas aos pares, mas também dos pares e com os pares. Apesar das mudanças nos sorrisos dos bebês ao longo do tempo, o processo não se manifestou de modo linear. Nas expressões de choro dos bebês não se observou mudanças nas interações com os pares, apenas diferenças na qualidade e duração de tempo. As interações de pares em que Tiago chorou estavam relacionadas, em sua maioria, ao incômodo decorrente de invasões físicas sobre o bebê. Já no caso de Bruno, na maior parte das vezes, as interações compreendiam incômodo por situações de competição ou perda de brinquedos. Em ambas as expressões estudadas, observamos que sorrisos, apesar de menos frequentes entre os pares, contagiaram mais do que os choros, no sentido de haver alguma reação por parte dos pares. É oportuno apontar, neste momento, a relevância de estudos futuros sobre esta temática investigativa, haja vista a importância e a riqueza das manifestações de expressividade emocional nas interações de bebês que convivem em ambiente coletivo.

Alfabetização no ensino fundamental: novas bases curriculares

Esta dissertação apresenta dados e discussões oriundos de uma experiência coletiva de pesquisa cujo objetivo maior consistiu em articular as bases curriculares da alfabetização no ensino fundamental de nove anos. A partir da transição histórica e política ocorrida pela Lei 11.274/1996, na qual o ensino fundamental passou a ter um ano a mais de duração e a receber as crianças que anteriormente eram atendidas na educação infantil, uma nova configuração se fez necessária. Demonstramos ao longo do trabalho a necessidade de: 1. Um plano que considere as transições (seja entre anos ou entre ciclos) e que sustente as continuidades; 2. Assumir, a partir do ano de ingresso no ensino fundamental, a perspectiva do regime de ciclo, definindo responsabilidades, objetivos e estratégias articuladas a partir de um trabalho em equipe; 3. Aprofundar conhecimentos que permitam considerar os aspectos mais subjetivos da relação educativa, considerando sempre a infância em seu encantamento lúdico; 4. Estabelecer uma relação dinâmica e produtiva entre oralidade e escrita, entre língua e literatura; 5. Dar maior precisão ao manejo da heterogeneidade desde a série de ingresso enfatizando o acompanhamento de singularidades e diferenças como forma de resolver o problema dos desníveis em alfabetização. A perspectiva teórica parte da articulação de várias áreas e temas do conhecimento: a história da escrita; pesquisa sobre oralidade ou cultura oral em tensão com a escrita; a psicanálise e a educação. Pretendemos, a partir das experiências e reflexões apresentadas nesse trabalho, contribuir para as políticas públicas enfatizando a grande relevância do ensino da escrita e da leitura nas séries iniciais do ensino fundamental. Ao longo dessas experiências, constatamos que, para formar leitores e escritores de bom nível na escola pública brasileira, precisamos de um modelo de trabalho coletivo mais complexo, capaz de exercer um manejo pedagógico detalhado, e ampliamos nossa consciência de que nossas buscas metodológicas, nossas experiências e nossos esforços coletivos em torno da heterogeneidade, apesar de consistentes e relevantes, só poderão ser sustentados a partir de uma reorganização do trabalho escolar que insista em fazer da alfabetização e da leitura uma verdadeira prioridade.

Acting White Among Black College Students: A Phenomenological Study of Social Constructions of Race

This study was a qualitative examination of Black college students' experiences with the Acting White label. In conducting this study, two gaps in literature were addressed: (1) the lack of literature on Black college students and the acting white label, and (2) lack of attention to a US racial history and current structures which allow a label such as "acting white" to exist. Thus, the purpose of this study was to call attention to the experiences of Black college students as it relates to the acting white label. Additionally, the study calls attention to social constructions that allow the acting white label to exist and to be sustained. Data was collected from 14 Black college students at a predominantly white, private, liberal arts university in the west. Based on responses from students in the study, Black college students do hear that they are acting white. Yet, their reaction to hearing the label does not cause them to underachieve academically, but does have an impact on their social actions. The ways in which Black college students in the study were labeled as acting white was based on academic pursuits, speech patterns, dress, and hobbies. Student reactions to the label ranged from ignoring the label to challenging the accuser. In regards to how the acting white label is sustained, students in the study expressed that they learned what it meant to act white or black from family interactions, social interactions and observations from family and friends, and from media sources. It was concluded that Black college students, despite reactions, do hear the label and that the label seems to be used as a means to attack Black students and their identity.

A Qualitative Study of Potential Suicide Risk Factors Among Soldiers Transitioning From Operation Iraqi Freedom/Operation Enduring Freedom

Using qualitative methods, this study explored potential risk factors for suicide, as defined by Joiner's Interpersonal-Psychological Theory of Suicide (IPTS), in a population of Soldiers returning from deployment in Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF). Sixty-eight Soldiers participated in semi-structured interviews during the period of transition from deployment to the garrison environment. These Soldiers were asked about changes in perception of pain, experiences of perceived burdensomeness, and lack of belonging. Interviews were transcribed and analyzed. A phenomenological methodology was employed (Creswell, 2006). In response to questions about perception of pain, Soldiers discussed both positive and negative changes in their experience of physical and emotional pain. When asked about experiences of perceived burdensomeness, Soldiers described changes related to deployment, such as injuries and combat related guilt, as well as changes related to transition from combat, including care seeking, reintegration into family and society, and emotional distancing. Regarding the experience of lack of belonging, Soldiers described difficulties related to the deployment, such as combat injuries, leadership roles, and individual differences, as well as difficulties related to reintegration such as symptoms of emotional numbing and distancing. Findings highlight the potential utility of IPTS in exploring both acute and chronic suicide risk factors associated with deployment and transition, as well as potential treatment strategies that may reduce suicide risk in the population of Soldiers during reintegration.

The Future Direction of Delaware Law (Including a Brief Exegesis on Fee Shifting Bylaws)

Delaware sets the governance standards for most public companies. The ability to attract corporations could not be explained solely by the existence of a favorable statutory regime. Delaware was not invariably the first or the only state to implement management friendly provisions. Given the interpretive gaps in the statute and the critical importance of the common law in the governance process, courts played an outsized role in setting legal standards. The management friendly nature of the Delaware courts contributed significantly to the state’s attraction to public corporations. A current example of a management friendly trend in the case law had seen the recent decisions setting out the board’s authority to adopt bylaws under Section 109 of the Delaware General Corporation Law (DGCL), particularly those involving the shifting of fees in litigation against the corporation or its directors. The DGCL allows bylaws that address “the business of the corporation, the conduct of its affairs, and its rights or powers or the rights or powers of its stockholders, directors, officers or employees.” The broad parameters are, however, subject to limits. Bylaws cannot be inconsistent with the certificate of incorporation or “the law.” Law includes the common law. The Delaware courts have used the limitations imposed by “the law” to severely restrict the reach of shareholder inspired bylaws. The courts have not used the same principles to impose similar restraints on bylaws adopted by the board of directors. This can be seen with respect to bylaws that restrict or even eliminate the right of shareholders to bring actions against management and the corporation. In ATP Tour, Inc. v. Deutscher Tennis Bund the court approved a fee shifting bylaw that had littl relationship to the internal affairs of the corporation. The decision upheld the bylaw as facially valid.The decision ignored a number of obvious legal infirmities. Among other things, the decision did not adequately address the requirement in Section 109(b) that bylaws be consistent with “the law.” The decision obliquely acknowledged that the provisions would “by their nature, deter litigation” but otherwise made no effort to assess the impact of this deterrence on shareholders causes of action. The provision in fact had the practical effect of restricting, if not eliminating, litigation rights granted by the DGCL and the common law. Perhaps most significantly, however, the bylaws significantly limited common law rights of shareholders to bring actions against the corporation and the board. Given the high dismissal rates for these actions, fee shifting bylaws imposed a meaningful risk of liability on plaintiffs. Moreover, because judgments in derivative suits were paid to the corporation, shareholders serving as plaintiffs confronted the risk of liability without any offsetting direct benefit. By preventing suits in this area, the bylaw effectively insulated the behavior of boards from legal challenge. The ATP decision was poorly reasoned and overstepped acceptable boundaries. The management friendly decision threatened the preeminent role of Delaware in the development of corporate law. The decision raised the specter of federal intervention and the potential for meaningful competition from the states. Because the opinion examined the bylaw in the context of non-stock companies, the reasoning may remain applicable only to those entities and never make the leap to for-profit stock corporations. Nonetheless, the analysis reflects a management friendly approach that does not adequately take into account the impact of the provision on the rights of shareholders.

Governance and Uncertainty

Government actors create law against a backdrop of uncertainty. Limited information, unpredictable events, and lack of understanding interfere with accurately predicting a legal regime’s costs, benefits, and effects on other legal and social programs and institutions. Does the availability of no-fault divorce increase the number of terminated marriages? Will bulk-collection of telecommunications information about American citizens reveal terrorist plots? Can a sensitive species breed in the presence of oil and gas wells? The answers to these questions are far from clear, but lawmakers must act nonetheless. The problems posed by uncertainty cut across legal fields. Scholars and regulators in a variety of contexts recognize the importance of uncertainty, but no systematic, generally-applicable framework exists for determining how law should account for gaps in information. This Article suggests such a framework and develops a novel typology of strategies for accounting for uncertainty in governance. This typology includes “static law,” as well as three varieties of “dynamic law.” “Static law” is a legal rule initially intended to last in perpetuity. “Dynamic law” is intended to change, and includes: (1) durational regulation, or fixed legal rules with periodic opportunities for amendment or repeal; (2) adaptive regulation, or malleable legal rules with procedural mechanisms allowing rules to change; and (3) contingent regulation, or malleable legal rules with triggering mechanisms to substantively change to the rules. Each of these strategies, alone or in combination, may best address the uncertainty inherent in a particular lawmaking effort. This Article provides a diagnostic framework that lawmakers can use to identify optimal strategies. Ultimately, this approach to uncertainty yields immediate practical benefits by enabling lawmakers to better structure governance.

JRNL: Journal Retention and Needs Listing — A Software Tool for Managing Print Journal Archives

The Journal Retention and Needs Listing (JRNL) program: 1) allows libraries to expose lists of print journals for which they have made retention commitments; 2) express needs (or gaps) in their holdings; and 3) communicate offers to fill the gaps in other participating libraries’ holdings. Multiple library consortia and their member libraries use JRNL to facilitate communication between library staff to identify holding commitments, fill gaps, and guide deselection decisions. JRNL is commonly developed and governed by the participating consortia. Currently, those consortia are the Florida Academic Repository (FLARE), the Association of Southeastern Research Libraries (ASERL)/Washington Research Library Consortium (WRLC), and the Western Regional Storage Trust (WEST).

Modelling liquid–liquid equilibria for island type ternary systems

Closed miscibility gaps in ternary liquid mixtures, at constant temperature and pressure, are obtained if phase separations occur only in the ternary region, whilst all binary mixtures involved in the system are completely miscible. This type of behaviour, although not very frequent, has been observed for a certain number of systems. Nevertheless, we have found no information about the applicability of the common activity coefficient models, as NRTL and UNIQUAC, for these types of ternary systems. Moreover, any of the island type systems published in the most common liquid–liquid equilibrium data collections, are correlated with any model. In this paper, the applicability of the NRTL equation to model the LLE of island type systems is assessed using topological concepts related to the Gibbs stability test. A first attempt to correlate experimental LLE data for two island type ternary systems is also presented.

Looking twice at the gender equity index for public health impact

Background: It has been shown that gender equity has a positive impact on the everyday activities of people (decision making, income allocation, application and observance of norms/rules) which affect their health. Gender equity is also a crucial determinant of health inequalities at national level; thus, monitoring is important for surveillance of women’s and men’s health as well as for future health policy initiatives. The Gender Equity Index (GEI) was designed to show inequity solely towards women. Given that the value under scrutiny is equity, in this paper a modified version of the GEI is proposed, the MGEI, which highlights the inequities affecting both sexes. Methods: Rather than calculating gender gaps by means of a quotient of proportions, gaps in the MGEI are expressed in absolute terms (differences in proportions). The Spearman’s rank coefficient, calculated from country rankings obtained according to both indexes, was used to evaluate the level of concordance between both classifications. To compare the degree of sensitivity and obtain the inequity by the two methods, the variation coefficient of the GEI and MGEI values was calculated. Results: Country rankings according to GEI and MGEI values showed a high correlation (rank coef. = 0.95). The MGEI presented greater dispersion (43.8%) than the GEI (19.27%). Inequity towards men was identified in the education gap (rank coef. = 0.36) when using the MGEI. According to this method, many countries shared the same absolute value for education but with opposite signs, for example Azerbaijan (−0.022) and Belgium (0.022), reflecting inequity towards women and men, respectively. This also occurred in the empowerment gap with the technical and professional job component (Brunei:-0.120 vs. Australia, Canada Iceland and the U.S.A.: 0.120). Conclusion: The MGEI identifies and highlights the different areas of inequities between gender groups. It thus overcomes the shortcomings of the GEI related to the aim for which this latter was created, namely measuring gender equity, and is therefore of great use to policy makers who wish to understand and monitor the results of specific equity policies and to determine the length of time for which these policies should be maintained in order to correct long-standing structural discrimination against women.

Detección de puntos débiles de aislamiento acústico en edificación ya construida

El aislamiento acústico es un problema de difícil solución una vez que la obra ya está acabada. En el caso de que la obra esté finalizada y no se cumplan con los valores de calidad acústicos que nos marca la legislación, deben detectarse los puntos débiles que provocan esa deficiencia de aislamiento acústico. La publicación de catálogos de soluciones constructivas hace que el problema no sea el material elegido, sino cómo se han unido estos materiales entre sí. Por tanto, debe analizarse este problema y buscar mecanismos con los que determinar los puntos débiles. En este trabajo se propone un método para la determinación de caminos débiles de transmisión entre un recinto emisor y un recinto receptor. El método obtiene el índice de reducción vibracional, como indicador de estos caminos débiles. Se muestran en el trabajo varios casos estudiados en el propio edificio, y cómo valorar la transmisión que debilita el aislamiento global de todo el conjunto constructivo.

Are drawings dead? …and performance over aesthetics?

When the act of 'drawing' became what can only be called formalised, (whose growth can be said to have blossomed during the Renaissance), there developed a separation between the drawing and its procurement. Recently, David Ross Scheer, in his book ‘The Death of Drawing, Architecture in the Age of Simulation’ wrote: ‘…whereas architectural drawings exist to represent construction, architectural simulations exist to anticipate building performance.’ Meanwhile, Paolo Belardi, in his work ‘Why Architects Still Draw’ likens a drawing to an acorn, where he says: ‘It is the paradox of the acorn: a project emerges from a drawing – even from a sketch, rough and inchoate - just as an oak tree emerges from an acorn.’ He tells us that Giorgio Vasari would work late at night ‘seeking to solve the problems of perspective’ and he makes a passionate plea that this reflective process allows the concept to evolve, grow and/or develop. However, without belittling Belardi, the virtual model now needs this self-same treatment where it is nurtured, coaxed and encouraged to be the inchoate blueprint of the resultant oak tree. The model now too can embrace the creative process going through the first phase of preparation, where it focuses on the problem. The manipulation of the available material can then be incubated so that it is reasoned and generates feedback. This paper serves to align this shift in perception, methodologies and assess whether the 2D paper abstraction still has a purpose and role in today’s digital world!
