Families with a child on chronic peritoneal dialysis have to assume a significant burden of care, intensifying the demands and the reorganization of roles in the families of children. The purpose of this study is to describe the implications of role changes in families of children with chronic renal disease on peritoneal dialysis. This is a case study of four families of children with chronic renal disease on peritoneal dialysis. Fourteen family members participate in the study. After the childs chronic kidney failure and the start of treatment, each relatives ways, acts and functions are changed, maintained or adapted to the new family dynamics, imposed by the child`s treatment conditions. Appropriate role assessment provides the nurse and the families of children with chronic renal failure on peritoneal dialysis with insight regarding current and potential health problems and aids in identifying the needs of the families.; Sao Paulo State (FAPESP); National Council for Scientific and Technological Development (CNPq); Coordination for the Improvent of Higher Education Personnel ( CAPES)

Genetic variability in S(1) families from different maize populations. The objectives of the present work were directed towards the study of genetic: variablilty In seven maize populations with a broad genetic base, as a guide for population improvement. The field evaluation was conducted in completely randomized blocks, at one location (Anhembi, Sao Paulo state) with different groups, of S(1) families Obtained from seven populations (GO-D: dent type, GO-F: flint type, GO-L: long car, GO-G: thick Car; and composites G3, G4 and GO-S). Estimates were obtained for genetic variance (progeny mean basis), phenotypic variance of families means, and coefficient of heritability (broad sense) for progeny means. Estimates of heritability were high for Car weight (0,89 to 0.94), car length (0.77 to 0.88) and car diameter (0.77 to 0.92); and lower for plant height (0.58 to 0.80) and Car height (0.54 to 0.84), thus showing the high Potential of the populations for recurrent selection based oil S, families. Ear yield in the base populations used as controls varied front 11,200 kg ha(-1) (GO-D) to 12,800 kg ha(-1) (G3). The means of S(1) families varied from 6,070 kg ha(-1) (GO-F) to 7,380 kg ha(-1) (G4); the Inbreeding depression in S(1) Families varied front 37.5% (G4) to 48.0% (G3) relative to the non-inbred population.

Background: We studied the characteristics of family functioning in bipolar children and healthy comparison children. We hypothesized that the family environment of bipolar children would show greater levels of dysfunction as measured by the Family Environment Scale (FES). Methods: We compared the family functioning of 36 families that included a child with DSM-IV bipolar disorder versus 29 comparison families that included only healthy children. All subjects and their parents were assessed with the K-SADS-PL interview. The parents completed the FES to assess their current family functioning. Multivariate analysis of variance was used to compare the family environment of families with and without offspring with bipolar disorder. Results: Parents of bipolar children reported lower levels of family cohesion (p<0.001), expressiveness (p=0.005), active-recreational orientation (p<0.001), intellectual-cultural orientation (p=0.04) and higher levels of conflict (p<0.001) compared to parents with no bipolar children. Secondary analyses within the bipolar group revealed lower levels of organization (p=0.03 1) and cohesion (p=0.014) in families where a parent had a history of mood disorders compared to families where parents had no history of mood disorders. Length of illness in the affected child was inversely associated with family cohesion (r=-0.47...

No contexto de estruturação do Sistema Único de Assistência Social, no qual os profissionais da psicologia passam a compor obrigatoriamente as equipes de atenção a famílias e indivíduos em situação de vulnerabilidade social, o objetivo desta pesquisa foi refletir sobre as possibilidades teórico-práticas da psicologia na proteção social básica, com base na interlocução com famílias de um garimpo de cassiterita na Amazônia Ocidental. Para tanto, realizou-se um estudo de cunho etnográfico, de incursões com frequencia semanal, durante aproximadamente um ano, no qual foram realizadas observações participantes, conversas informais e entrevistas semiestruturadas com os residentes do local. Buscou-se entender o contexto histórico e social do garimpo; as histórias familiares; os aspetos do cotidiano familiar; os sentidos e as expectativas de futuro das famílias; as formas de organização coletiva e participação social; bem como, os sentidos e experiências das famílias com a psicologia. A análise foi realizada à luz da abordagem teórica da psicologia histórico-cultural, que busca articular as dimensões subjetiva e objetiva, singular e coletiva, para o entendimento dos sujeitos e dos sentidos/significados por eles atribuídos às suas vivências. Os resultados revelaram como as condições objetivas de pobreza...

Investigações epidemiológicas apontam que as taxas de incidência e prevalência da negligência são as mais altas em vários países do mundo, bem como no Brasil. No nosso contexto, as investigações sobre o tema são raras e o conhecimento limitado. Buscando contribuir para uma melhor compreensão da negligência no contexto Brasileiro, o presente estudo teve como objetivo estudar a manifestação da negligência em casos notificados ao Conselho Tutelar, tentando apreender os mecanismos de produção subjacentes, de modo a se estabelecer parâmetros com vistas à avaliação dos casos. Para tal, utilizou-se proposições teóricas já estabelecidas pela literatura científica atinentes a critérios relacionados à manifestação do problema e aos mecanismos relacionados à sua produção. O delineamento metodológico foi o de Estudo de Casos Múltiplos, dentro de uma abordagem qualitativa de pesquisa. A coleta de dados ocorreu no contexto de vida das famílias, em um contexto de acompanhamento psicossocial, que teve a duração de 10 meses, utilizando-se de observação participante, entrevistas e utilização de instrumentos padronizados. No total, 12 famílias foram estudadas. As informações, coletadas por meio das diferentes estratégias...

## Lower order terms in the 1-level density for families of holomorphic cuspidal newforms

The Katz-Sarnak density conjecture states that, in the limit as the conductors tend to infinity, the behavior of normalized zeros near the central point of families of L-functions agree with the N -> oo scaling limits of eigenvalues near 1 of subgroups of U(N). Evidence for this has been found for many families by studying the n-level densities; for suitably restricted test functions the main terms agree with random matrix theory. In particular, all one-parameter families of elliptic curves with rank r over Q(T) and the same distribution of signs of functional equations have the same limiting behavior. We break this universality and find family dependent lower order correction terms in many cases; these lower order terms have applications ranging from excess rank to modeling the behavior of zeros near the central point, and depend on the arithmetic of the family. We derive an alternate form of the explicit formula for GL(2) L-functions which simplifies comparisons, replacing sums over powers of Satake parameters by sums of the moments of the Fourier coefficients lambda_f(p). Our formula highlights the differences that we expect to exist from families whose Fourier coefficients obey different laws (for example, we expect Sato-Tate to hold only for non-CM families of elliptic curves).

Ahlswede and Khachatrian's diametric theorem is a weighted version of their complete intersection theorem, itself an extension of the $t$-intersecting Erd\H{o}s-Ko-Rado theorem. Their intersection theorem says that the maximum size of a family of subsets of $[n] = \{1, \dots, n\}$, every pair of which intersects in at least $t$ elements, is the size of certain trivially intersecting families proposed by Frankl. We address a cross intersecting version of their diametric theorem. Two families $\mathcal{A}$ and $\mathcal{B}$ of subsets of $[n]$ are {\em cross $t$-intersecting} if for every $A \in \mathcal{A}$ and $B \in \mathcal{B}$, $A$ and $B$ intersect in at least $t$ elements. The $p$-weight of a $k$ element subset $A$ of $[n]$ is $p^{k}(1-p)^{n-k}$, and the weight of a family $\mathcal{A}$ is the sum of the weights of its sets. The weight of a pair of families is the product of the weights of the families. The maximum $p$-weight of a $t$-intersecting family depends on the value of $p$. Ahlswede and Khachatrian showed that for $p$ in the range $[\frac{r}{t + 2r - 1}, \frac{r+1}{t + 2r + 1}]$, the maximum $p$-weight of a $t$-intersecting family is that of the family $\mathcal{F}^t_r$ consisting of all subsets of $[n]$ containing at least $t+r$ elements of the set $[t+2r]$. In a previous paper we showed a cross $t$-intersecting version of this for large $t$ in the case that $r = 0$. In this paper...

The goal of this paper is to compute the cuspidal Calogero-Moser families for all infinite families of finite Coxeter groups, at all parameters. We do this by first computing the symplectic leaves of the associated Calogero-Moser space and then by classifying certain "rigid" modules. Numerical evidence suggests that there is a very close relationship between Calogero-Moser families and Lusztig families. Our classification shows that, additionally, the cuspidal Calogero-Moser families equal cuspidal Lusztig families for the infinite families of Coxeter groups.; Comment: 40 pages.

We are proposing a new way of describing families of quarks and leptons, using the approach unifying all the internal degrees of freedom, proposed by one of us. Spinors, living in d(=1+13)-dimensional space, carry in this approach only the spin and interact with only the gravity through vielbeins and two kinds of the spin connection fields - the gauge fields of the Poincare group and the second kind of the Clifford algebra objects. All the quarks and the leptons of one family appear in one Weyl representation of a chosen handedness of the Lorentz group, if analyzed with respect to the Standard model gauge groups: the right handed (with respect to SO(1,3)) weak chargeless quarks and leptons and the left handed weak charged quark and leptons. A part of the starting Lagrange density of a Weyl spinor in d=1+13 transforms right handed quarks and leptons into left handed quarks and leptons manifesting as the Yukawa couplings of the Standard model. The second kind of Clifford algebra objects generates families and contributes to diagonal and off diagonal Yukawa couplings. The approach predicts an even number of families, treating leptons and quarks equivalently. In this paper we investigate within this approach the appearance of the Yukawa couplings within one family of quarks and leptons as well as among the families (without assuming any Higgs fields). We present the mass matrices for four families and investigate whether our way of generating families might explain the origin of families of quarks and leptons as well as their observed properties - the masses and the mixing matrices. Numerical results are presented in the paper following this one.; Comment: 34 pages...

This contribution is an attempt to try to understand the matter-antimatter asymmetry in the universe within the {\it spin-charge-family-theory} if assuming that transitions in non equilibrium processes among instanton vacua and complex phases in mixing matrices are the sources of the matter-antimatter asymmetry, as studied in the literature for several proposed theories. The {\it spin-charge-family-theory} is, namely, very promising in showing the right way beyond the {\it standard model}. It predicts families and their mass matrices, explaining the origin of the charges and of the gauge fields. It predicts that there are, after the universe passes through two $SU(2)\times U(1)$ phase transitions, in which the symmetry breaks from $SO(1,3) \times SU(2) \times SU(2) \times U(1) \times SU(3)$ first to $SO(1,3) \times SU(2) \times U(1) \times SU(3)$ and then to $SO(1,3) \times U(1) \times SU(3)$, twice decoupled four families. The upper four families gain masses in the first phase transition, while the second four families gain masses at the electroweak break. To these two breaks of symmetries the scalar non Abelian fields, the (superposition of the) gauge fields of the operators generating families, contribute. The lightest of the upper four families is stable (in comparison with the life of the universe) and is therefore a candidate for constituting the dark matter. The heaviest of the lower four families should be seen at the LHC or at somewhat higher energies.; Comment: 21 pages...

Primary Cosmic Ray Chemical Composition is investigated in energy region close to 10**16 eV. Studies are based on comparisons of gamma-hadron families observed by Pamir and Pamir-Chacaltaya Collaboration, with families generated by means of quasi-scaling model MC0. It is shown, that all characteristics of observed families, including their intensity, are in a very good agreement with simulated event properties at the normal chemical composition and are in disagreement at heavy dominant compositions. Code CORSICA with VENUS and DPM models also contradicts with experimental data of families. One- and multi-dimensional methods of recognition of Fe-like families is worked up and approved. They are based on family characteristics sensitive to atomic number of induced nuclei and are not correlated between each others. It is shown that the fraction of Fe-like families is consistent with the normal chemical composition and strongly contradicts to heavy dominant ones. The success of MC0 model, in description of families properties, is due to large inelasticity coefficient of soft interactions at superhigh energies.; Comment: 32 pages (REVTeX), 10 eps figures.

Aydinian et al. [J. Combinatorial Theory A 118(2)(2011), 702-725] substituted the usual BLYM inequality for L-Sperner families with a set of M inequalities for $(m_1,m_2,...,m_M;L_1,L_2,...,L_M)$ type M-part Sperner families and showed that if all inequalities hold with equality, then the family is homogeneous. Aydinian et al. [Australasian J. Comb. 48(2010), 133-141] observed that all inequalities hold with equality if and only if the transversal of the Sperner family corresponds to a simple mixed orthogonal array with constraint M, strength M-1, using $m_i+1$ symbols in the $i^{\text{th}}$ column. In this paper we define $k$-dimensional $M$-part Sperner multi-families with parameters $L_P: P\in\binom{[M]}{k}$ and prove $\binom{M}{k}$ BLYM inequalities for them. We show that if k

We consider a supercritical branching population, where individuals have i.i.d. lifetime durations (which are not necessarily exponentially distributed) and give birth (singly) at constant rate. We assume that individuals independently experience neutral mutations, at constant rate $\theta$ during their lifetimes, under the infinite-alleles assumption: each mutation instantaneously confers a brand new type, called allele or haplotype, to its carrier. The type carried by a mother at the time when she gives birth is transmitted to the newborn. We are interested in the sizes and ages at time $t$ of the clonal families carrying the most abundant alleles or the oldest ones, as $t\to\infty$, on the survival event. Intuitively, the results must depend on how the mutation rate $\theta$ and the Malthusian parameter $\alpha>0$ compare. Hereafter, $N\equiv N_t$ is the population size at time $t$, constants $a,c$ are scaling constants, whereas $k,k'$ are explicit positive constants which depend on the parameters of the model. When $\alpha>\theta$, the most abundant families are also the oldest ones, they have size $cN^{1-\theta/\alpha}$ and age $t-a$. When $\alpha<\theta$, the oldest families have age $(\alpha /\theta)t+a$ and tight sizes; the most abundant families have sizes $k\log(N)-k'\log\log(N)+c$ and all have age $(\theta-\alpha)^{-1}\log(t)$. When $\alpha=\theta$...

The RNA world hypothesis, that RNA genomes and catalysts preceded DNA genomes and genetically-encoded protein catalysts, has been central to models for the early evolution of life on Earth. A key part of such models is continuity between the earliest stages in the evolution of life and the RNA repertoires of extant lineages. Some assessments seem consistent with a diverse RNA world, yet direct continuity between modern RNAs and an RNA world has not been demonstrated for the majority of RNA families, and, anecdotally, many RNA functions appear restricted in their distribution. Despite much discussion of the possible antiquity of RNA families, no systematic analyses of RNA family distribution have been performed. To chart the broad evolutionary history of known RNA families, we performed comparative genomic analysis of over 3 million RNA annotations spanning 1446 families from the Rfam 10 database. We report that 99% of known RNA families are restricted to a single domain of life, revealing discrete repertoires for each domain. For the 1% of RNA families/clans present in more than one domain, over half show evidence of horizontal gene transfer, and the rest show a vertical trace, indicating the presence of a complex protein synthesis machinery in the Last Universal Common Ancestor (LUCA) and consistent with the evolutionary history of the most ancient protein-coding genes. However...

A minimal family of curves on an embedded surface is defined as a 1-dimensional family of rational curves of minimal degree, which cover the surface. We classify such minimal families using constructive methods. This allows us to compute the minimal families of a given surface. The classification of minimal families of curves can be reduced to the classification of minimal families which cover weak Del Pezzo surfaces. We classify the minimal families of weak Del Pezzo surfaces and present a table with the number of minimal families of each weak Del Pezzo surface up to Weyl equivalence. As an application of this classification we generalize some results of Schicho. We classify algebraic surfaces which carry a family of conics. We determine the minimal lexicographic degree for the parametrization of a surface which carries at least 2 minimal families.

This is the final version of the article. It was first available from BioMed Central via http://dx.doi.org/10.1186/s12889-015-2497-4; Purpose: Family-based interventions present a much-needed opportunity to increase children?s physical activity levels. However, little is known about how best to engage parents and their children in physical activity research. This study aimed to engage with the whole family to understand how best to recruit for, and retain participation in, physical activity research. Methods: Families (including a ?target? child aged between 8 and 11 years, their parents, siblings, and others) were recruited through schools and community groups. Focus groups were conducted using a semi-structured approach (informed by a pilot session). Families were asked to order cards listing the possible benefits of, and the barriers to, being involved in physical activity research and other health promotion activities, highlighting the items they consider most relevant, and suggesting additional items. Duplicate content analysis was used to identify transcript themes and develop a coding frame. Results/findings: Eighty-two participants from 17 families participated, including 17 ?target? children (mean age 9.3 ? 1.1 years...

This dissertation examines racial socialization in Afro-Brazilian families in order to understand how phenotypically diverse families negotiate racial hierarchies and ideologies of white supremacy. As an inductive, qualitative project, this research is based on over fourteen months of ethnographic fieldwork in Salvador, Bahia, Brazil in fifteen poor and working-class Bahian families and 116 semi-structured interviews with family members and informants. Findings suggest that one of the most prominent features of racial socialization is the pervasive devaluation of black/African influences, which is conveyed through implicit and explicit messages as well as concrete practices (including rituals) that promote the stigmatization of negatively valued racialized physical features. The study reveals a pattern of unequal distribution of affection based on racial appearance (phenotype), which is evident in parent-child, sibling, extended family, and romantic relationships. Findings suggest that negative appraisals of racial phenotype may significantly compromise affective bonds in families and have social psychological consequences impacting self-esteem and sense of belonging, while also eliciting suicidal ideations and anxieties. These outcomes are most pronounced for Afro-Brazilian females. Racial socialization also conveys the "strategically ambiguous" logic of color and racial classification...
