Although general parenting styles and restrictive parental feeding practices have been associated with children's weight status, few studies have examined the association between feeding styles and proximal outcomes such as children's food intake, especially in multi-ethnic families with limited incomes. The purpose of this study was to evaluate the association of parental feeding styles and young children's evening food intake in a multiethnic sample of families in Head Start. Participants were 715 Head Start children and their parents from Texas and Alabama representing three ethnic groups: African-American (43%), Hispanic (29%), and White (28%). The Caregivers Feeding Styles Questionnaire (Hughes) was used to characterize authoritative, authoritarian (referent), indulgent or uninvolved feeding styles. Food intake in several food groups was calculated from 3 days of dietary recalls for the child for evening food intakes from 3 PM until bedtime. Compared to children of authoritarian parents, intakes of fruits, juice and vegetables were lowest among children of indulgent or uninvolved parents (1.77 +/- 0.09 vs 1.45 +/- 0.09 and 1.42 +/- 0.11 cups) as were intakes of dairy foods (0.84 +/- 0.05 vs 0.67 +/- 0.05 and 0.63+0.06 cups), respectively. Findings suggest that permissive parent feeding styles like indulgent or uninvolved relate negatively to children's intake of nutrient-rich foods fruit, 100% fruit juice, vegetables and dairy foods from 3 PM until bedtime.

The Cosmological Constant and Domain Walls in Orientifold Field Theories and N=1 Gluodynamics

2003-01-01

We discuss domain walls and vacuum energy density (cosmological constant) in N=1 gluodynamics and in non-supersymmetric large N orientifold field theories which have been recently shown to be planar equivalent (in the boson sector) to N=1 gluodynamics. A relation between the vanishing force between two parallel walls and vanishing cosmological constant is pointed out. This relation may explain why the cosmological constant vanishes in the orientifold field theory at leading order although the hadronic spectrum of this theory does not contain fermions in the limit N-->infinity. The cancellation is among even and odd parity bosonic contributions, due to NS-NS and R-R cancellations in the annulus amplitude of the underlying string theory. We use the open-closed string channel duality to describe interaction between the domain walls which is interpreted as the exchange of composite ``dilatons'' and ``axions'' coupled to the walls. Finally, we study some planar equivalent pairs in which both theories in the parent...

Class of very simple gauge theories which remain renormalizable even in the limit of infinite gauge coupling constant

International Nuclear Information System (INIS)

Kaptanoglu, S.

1983-01-01

A class of local gauge theories based on compact semisimple Lie groups is studied in the limit of infinite gauge coupling constant (g = infinity). In general, in this limit, the gauge fields become auxiliary in all gauge theories, and the system develops a richer structure of constraints. Unfortunately for most gauge theories, this limit turns out to be too singular to quantize and the theory ceases to be renormalizable. For a special class of gauge theories, however, where there are no fermions and there is only one multiplet of scalars in the adjoint representation, we prove that a consistent renormalizable quantum theory exists even in this very singular limit. We trace this exceptional behavior to a new local translationlike symmetry in the functional space that this class of gauge models possesses in the limit of infinite gauge coupling constant. By carrying out the constraint analysis, evaluating the Faddeev-Popov-Senjanovic determinant, and doing the functional integrations over the canonical momenta, the gauge fields, and most of the components of the scalar fields, we obtain an extremely simple result with no non-Abelian structure left in it. For example, for the group SU(2), the final answer reduces to the theory of a one-component self-interacting real phi 4 scalar field theory. Throughout this paper, we use functional methods and make no approximations; our results are nonperturbative and exact. We also discuss some of the possible implications of our results

When it is costly to have a caring mother: food limitation erases the benefits of parental care in earwigs

OpenAIRE

Meunier Joel; Koelliker Mathias

2012-01-01

The aggregation of parents with offspring is generally associated with different forms of care that improve offspring survival at potential costs to parents. Under poor environments, the limited amount of resources available can increase the level of competition among family members and consequently lead to adaptive changes in parental investment. However, it remains unclear as to what extent such changes modify offspring fitness, particularly when offspring can survive without parents such a...

Janvier, Annie; Lorenz, John M; Lantos, John D

2012-08-01

When physicians are asked for a consult for women in premature labour, they face a complex set of challenges. Policy statements recommend that women be given detailed information about the risks of various outcomes, including death, long-term disability and various specific neonatal problems. Both personal narratives and studies suggest that parents also base their decisions on factors other than the probabilistic facts about expected outcomes. Statistics are difficult to understand at any time. Rational decision-making may be difficult when taking life-and-death decisions. Furthermore, the role of emotions is not discussed in peri-viability guidelines. We argue against trying to tell parents every fact that we think might be relevant to their decision. This may be overwhelming for many parents. Instead, doctors should try to discern, on a case-by-case basis, what particular parents want and need. Information and delivery of information should be personalized. Unfortunately, evidence in this area is limited. © 2012 The Author(s)/Acta Paediatrica © 2012 Foundation Acta Paediatrica.

Experiential studies in paediatric palliative care are needed to enable an ongoing international agenda which supports the development of responsive family supports. To provide an in-depth exploration of the prevalent lived experiences of parents who are currently providing care for a child with a life-limiting condition in Australia. Cross-sectional, prospective, qualitative study guided by an advisory group and reported according to the consolidated criteria for reporting qualitative studies. Transcripts were subjected to a thematic analysis, underpinned by an interpretative phenomenological framework. Purposively sampled parents (n = 14) recruited from a statewide paediatric hospice who self-identified as a 'primary caregiver' for one or more children and/or adolescents (⩽18 years) with a life-limiting condition. Four key themes represented the prevalent experiences of parents: (1) trapped inside the house, (2) the protector, (3) living with the shadow and (4) travelling a different pathway. They describe parents' physical and social isolation, exclusion from the workforce, pervasive grief and associated impacts to their health and well-being. Limited professional and diminished social supports resulted in full ownership of care responsibility. Yet, parents embraced their role as 'protector', reporting acquired meaning and purpose. This study builds upon the growing body of evidence available in paediatric palliative care internationally. The key themes highlight the substantial demand for both physical and emotional support beyond what is currently offered and call for the implementation of carefully planned support services and other societal initiatives which seek to alleviate the broad health impacts to caregivers. © The Author(s) 2016.

Communication between parents and their children about parental life-limiting illness is stressful. Parents want support from health-care professionals; however, the extent of this support is not known. Awareness of family's needs would help ensure appropriate support. To find the current literature exploring (1) how parents with a life-limiting illness, who have dependent children, perceive health-care professionals' communication with them about the illness, diagnosis and treatments, including how social, practical and emotional support is offered to them and (2) how this contributes to the parents' feelings of supporting their children. A systematic literature review and narrative synthesis. Embase, MEDLINE, PsycINFO, CINAHL and ASSIA ProQuest were searched in November 2015 for studies assessing communication between health-care professionals and parents about how to talk with their children about the parent's illness. There were 1342 records identified, five qualitative studies met the inclusion criteria (55 ill parents, 11 spouses/carers, 26 children and 16 health-care professionals). Parents wanted information from health-care professionals about how to talk to their children about the illness; this was not routinely offered. Children also want to talk with a health-care professional about their parents' illness. Health-care professionals are concerned that conversations with parents and their children will be too difficult and time-consuming. Parents with a life-limiting illness want support from their health-care professionals about how to communicate with their children about the illness. Their children look to health-care professionals for information about their parent's illness. Health-care professionals, have an important role but appear reluctant to address these concerns because of fears of insufficient time and expertise.

arbitration in respect of matrimonial matters. Lastly, the cost of parenting coordination is indicated as an area of contention. To properly address these problems, various safeguards for and limitations on parenting coordination practice are considered. It is proposed that the internationally accepted term "parenting coordination" is also consistently used in South Africa. It is further proposed that adequate qualifications, proper training and sufficient experience for parenting coordinators are set. To counter the argument that parenting coordination is an unlawful delegation of judicial power, the necessary authority for courts to refer parties for parenting coordination is sought, firstly in the inherent power of the High Court as upper guardian to ensure the best interests of children, and secondly in the Children's Act and the Constitution of the Republic of South Africa, 1996 as far as the children's court and divorce courts are concerned. In addition, various limitations regarding the conditions under which and the stage at which a parenting coordinator should be appointed, the scope of a parenting coordinator's decision-making powers and the finality of his or her directives are suggested. Lastly, the issue of the affordability of parenting coordination is addressed and suggestions are made on ways to provide fair access to this new intervention

Adolescents' video gaming is increasing at a rapid rate. Yet, little is known about what factors contribute toward more hours of gaming per week, as well as what factors may limit or protect adolescents from excessive gaming. The aim of the present study was to examine associations between adolescents' accessibility to video gaming devices, the locations played (i.e., bedroom, shared rooms), parental regulation of technology use, and the amount of hours spent video gaming during the week (weekdays vs. weekends). Adolescents (N=422; age 16.3±2.0 years, 41% male) completed an online questionnaire battery, including demographics, video gaming behaviors (e.g., hours played weekdays/weekends, time of day played, devices owned, locations played, etc.), and a questionnaire measuring aspects of parents' regulation of game playing (e.g., rules, limit setting, co-gaming). Accessibility to the adolescents' own devices, but not shared devices or device portability, was predictive of hours gaming on weekdays and weekends. Location (i.e., bedroom) was associated with increased gaming across the week. Parents discussing cybersafety was predictive of lower hours of gaming (weekdays and weekends). However, limit setting, monitoring, and co-gaming showed no significant effects. Adolescents' access to their own gaming equipped devices, as well as gaming in their bedrooms, were linked to increased hours of gaming. The findings suggest that in order to curb the increase in hours gaming, parents are advised to delay the ownership of adolescents' devices, encourage use in shared rooms, and discuss aspects of cybersafety with their teenage children.

Pediatric palliative care is an evolving field of practice in social work. As such, research plays a critical role in informing best social work practices in this area. For parents, caring for a child with a life-limiting illness (LLI) is a stressful experience that compounds the usual challenges of parenting. The negative aspects of caring for a child with an LLI are well documented. In the face of such adversity, parent caregivers can also experience positive changes caring for children with even the most serious conditions. This article presents results from a research study of posttraumatic growth in parents who are caring for a child with a LLI. Using mixed methods, two overarching themes were prominent in both the quantitative and qualitative data. The first describes stress related to financial burden associated with caregiving. The second theme concerns the posttraumatic growth experienced by the parent caregivers. The quantitative and qualitative data have been woven together to underscore issues and parental perspectives related to these two themes. This provides a unique and important platform for parent caregivers' experiences that can inform the work of social workers and other pediatric palliative care professionals.

Limits to the expansion of Earth, Moon, Mars and Mercury and to changes in the gravitational constant

It is stated that new estimates of the palaeoradius of the Earth for the past 400 Myr from palaeomagnetic data limit possible expansion to less than 0.8%, sufficient to exclude any current theory of Earth expansion. The lunar surface has remained static for 4,000 Myr with possible expansion limited to 0.06%, the Martian surface suggests a small possible expansion of 0.6%, while the surface of Mercury supports a small contraction. Observations of Mercury, together with reasonable assumptions about its internal structure, indicate that G decreased at a rate of less than 8 x 10 -12 yr -1 , in constant mass cosmologies, and 2.5 x 10 -11 yr -1 in Dirac's multiplicative creation cosmology.

Children, parents and home energy use: Exploring motivations and limits to energy demand reduction

International Nuclear Information System (INIS)

Fell, Michael J.; Chiu, Lai Fong

2014-01-01

While almost 30% of UK households include children, little research has attempted to present children's perspectives on home energy use. This study used focus groups with children and parents at two primary (elementary) schools in London, UK, to explore home energy use and energy feedback. Energy was found to be a little-discussed subject at home. Children derived more motivation to save energy from responsibility conferred by school activities than other (e.g. environmental) concerns, and some connected energy saving with dangers of using electricity (e.g. fire). Material and social constraints (e.g. access to outside space, parents' environmental attitudes) meant that it was sometimes difficult for children to save energy even when motivated. However, parents showed greater inclination to pay attention to energy saving when framed as supporting their child's learning than as a financial or environmental concern. Children were disinclined to reduce energy-consuming activities such as watching television, and while parents complained about children's energy use most saw it as a low priority issue. Policy implications of these findings are considered, and the approach employed is argued to be an effective way of investigating children's perceptions around energy use. - Highlights: • Separate focus groups were conducted with children and parents on home energy use. • Children were motivated to save energy by being given responsibility. • Parents viewed saving energy more positively when framed as educating their child. • Material and social factors limit children's ability to save energy. • The method may encourage openness by decreasing power imbalances

Limitations of the Conventional Phase Advance Method for Constant Power Operation of the Brushless DC Motor

The brushless dc motor (BDCM) has high-power density and efficiency relative to other motor types. These properties make the BDCM well suited for applications in electric vehicles provided a method can be developed for driving the motor over the 4 to 6:1 constant power speed range (CPSR) required by such applications. The present state of the art for constant power operation of the BDCM is conventional phase advance (CPA)[1]. In this paper, we identify key limitations of CPA. It is shown that the CPA has effective control over the developed power but that the current magnitude is relatively insensitive to power output and is inversely proportional to motor inductance. If the motor inductance is low, then the rms current at rated power and high speed may be several times larger than the current rating. The inductance required to maintain rms current within rating is derived analytically and is found to be large relative to that of BDCM designs using high-strength rare earth magnets. Th us, the CPA requires a BDCM with a large equivalent inductance

1986-01-01

The limitation of various typical flux-limited diffusion theory and advantages of asymptotic diffusion theory with time absorption constant are analyzed and compared. The conclusions are as following: Though the flux-limited problem in neutron diffusion theory are theoretically solved by derived flux-limited diffusion equation, it's going too far to limit flux due to the inappropriate assumption in deriving flux-limited diffusion equation. The asymptotic diffusion theory with time absorption constant has eliminated the above-mentioned limitation, and it is more accurate than flux-limited diffusion theory in describing neutron transport problem

Parents who use drugs parent in a context of heightened concern regarding the damaging effects of parental drug use on child welfare and family life. Yet there is little research exploring how parents who use drugs account for such damage and its limitation. We draw here upon analyses of audio......-recorded depth qualitative interviews, conducted in south-east England between 2008 and 2009, with 29 parents who use drugs. Our approach to thematic analysis treated accounts as co-produced and socially situated. An over-arching theme of accounts was 'damage limitation'. Most damage limitation work centred...... on efforts to create a sense of normalcy of family life, involving keeping drug use secret from children, and investing heavily in strategies to maintain ambiguity regarding children's awareness. Our analysis highlights that damage limitation strategies double-up in accounts as resources of child protection...

Semiclassical analysis of the weak-coupling limit of SU(2) lattice gauge theory: The subspace of constant fields

International Nuclear Information System (INIS)

Bartels, J.; Wu, T.T.

1988-01-01

This paper contains the first part of a systematic semiclassical analysis of the weak-coupling limit of lattice gauge theories, using the Hamiltonian formulation. The model consists of an N 3 cubic lattice of pure SU(2) Yang-Mills theory, and in this first part we limit ourselves to the subspace of constant field configurations. We investigate the flow of classical trajectories, with a particular emphasis on the existence and location of caustics. There the ground-state wave function is expected to peak. It is found that regions densely filled with caustics are very close to the origin, i.e., in the domain of weak field configurations. This strongly supports the expectation that caustics are essential for quantities of physical interest

Parenting behaviours are influenced by a range of factors, including parental functioning. Although common, the influence of parental fatigue on parenting practices is not known. The first aim of this study was to investigate the relationship between fatigue and parenting practices. The second aim was to identify parental psychosocial factors significantly associated with fatigue. A sample of 1276 Australian parents, of at least one child aged 0-5 years, completed a survey. Demographic, psychosocial (social support, coping responses) and parental sleep and self-care information was collected. Hierarchical regression was performed to assess the contribution of fatigue (modified Fatigue Assessment Scale) to parental practices (warmth, irritability and involvement), and parenting experiences (Parenting Stress Index, Parenting Sense of Competence Scale). Hierarchical multiple regression assessed the contribution of a range of parental sleep, psychosocial (social support, coping responses) and self-care variables to fatigue when demographic characteristics were held constant. Higher fatigue was significantly associated with lower parental competence (β=-0.17, P parenting stress (β= 0.21, P parent-child interactions (β= 0.11, P parental fatigue, including inadequate social support, poorer diet, poorer sleep quality and ineffective coping styles including self-blame and behaviour disengagement. Fatigue is common, and results suggest that fatigue contributes to adverse parental practices and experiences. However, possible risk factors for higher fatigue were identified in this study, indicating opportunities for intervention, management and support for parents. © 2011 Blackwell Publishing Ltd.

Quasar absorption spectra at 21-cm and UV rest wavelengths are used to estimate the time variation of x [triple-bond] alpha(2)g(p)mu, where alpha is the fine structure constant, g(p) the proton g factor, and m(e)/m(p) [triple-bond] mu the electron/proton mass ratio. Over a redshift range 0.24 < or = zeta(abs) < or = 2.04, (Deltax/x)(weighted)(total) = (1.17 +/- 1.01) x 10(-5). A linear fit gives x/x = (-1.43 +/- 1.27) x 10(-15) yr(-1). Two previous results on varying alpha yield the strong limits Deltamu/mu = (2.31 +/- 1.03) x 10(-5) and Deltamu/mu=(1.29 +/- 1.01) x10(-5). Our sample, 8 x larger than any previous, provides the first direct estimate of the intrinsic 21-cm and UV velocity differences 6 km s(-1).

Limitation on the constant of heavy lepton radiative decay according to data of the e+e- → γ + γ reactions

Gakh, G.I.

1976-01-01

The effect of a heavy lepton in an intermediate state on the differential and total cross sections of the e + e - → γγ reaction has been investigated in order to obtain information on heavy lepton radiative decay L → eγ. On the basis of experimental data on the reaction the limitations on the constant lambda of the decay L → eγ are obtained as functions of the heavy lepton mass. It turns out that the upper limit for lambda rapidly increases with the heavy lepton mass and at m > 1 GeV lambda 2 > 0.1

One in 10 US adults of childbearing age has limited English proficiency (LEP). Parental LEP is associated with worse health outcomes among healthy children. The relationship of parental LEP to health outcomes for children with special health care needs (CSHCN) has not been systematically reviewed. To conduct a systematic review of peer-reviewed literature examining relationships between parental LEP and health outcomes for CSHCN. PubMed, Scopus, Cochrane Library, Social Science Abstracts, bibliographies of included studies. Key search term categories: language, child, special health care needs, and health outcomes. US studies published between 1964 and 2012 were included if: 1) subjects were CSHCN; 2) studies included some measure of parental LEP; 3) at least 1 outcome measure of child health status, access, utilization, costs, or quality; and 4) primary or secondary data analysis. Three trained reviewers independently screened studies and extracted data. Two separate reviewers appraised studies for methodological rigor and quality. From 2765 titles and abstracts, 31 studies met eligibility criteria. Five studies assessed child health status, 12 assessed access, 8 assessed utilization, 2 assessed costs, and 14 assessed quality. Nearly all (29 of 31) studies used only parent- or child-reported outcome measures, rather than objective measures. LEP parents were substantially more likely than English-proficient parents to report that their CSHCN were uninsured and had no usual source of care or medical home. LEP parents were also less likely to report family-centered care and satisfaction with care. Disparities persisted for children with LEP parents after adjustment for ethnicity and socioeconomic status. Parental LEP is independently associated with worse health care access and quality for CSHCN. Health care providers should recognize LEP as an independent risk factor for poor health outcomes among CSHCN. Emerging models of chronic disease care should integrate and

General and food-selection specific parenting style in relation to the healthfulness of parent-child choices while grocery shopping.

Past research has demonstrated that parenting style is related to children's health and eating patterns, and that parenting can vary across time and context. However, there is little evidence about similarities and differences between general, self-reported parenting style and observed parenting during grocery shopping. The goals of this study were to investigate links between general parenting style, parental warmth and limit setting (important dimensions of parenting style) during grocery shopping, and the healthfulness of foods chosen. Participants were 153 parent (88 mothers) - child (6-9 years old) dyads. Dyads were brought to a laboratory set up like a grocery store aisle and asked to choose two items from each of three categories (cookies/crackers, cereals, chips/snacks). Parents were observed in terms of warmth, responsiveness, autonomy granting, and limit setting; children were observed in terms of resistance and negotiation. Parents reported behaviors related to general parenting. Regression analyses were used to test study hypotheses. Observed parental limit setting was related to general parenting style; observed warmth was not. Observed limit setting (but not observed warmth or self-reported parenting style) was related to the healthfulness of food choices. Limit setting appears to be the dimension of parenting style that is expressed during grocery shopping, and that promotes healthier food choices. Implications are discussed regarding consistencies in parenting style across situations as well as contributions of parenting style to the development of children's healthy eating.

Connecting Fundamental Constants

A model for a black hole electron is built from three basic constants only: h, c and G. The result is a description of the electron with its mass and charge. The nature of this black hole seems to fit the properties of the Planck particle and new relationships among basic constants are possible. The time dilation factor in a black hole associated with a variable gravitational field would appear to us as a charge; on the other hand the Planck time is acting as a time gap drastically limiting what we are able to measure and its dimension will appear in some quantities. This is why the Planck time is numerically very close to the gravitational/electric force ratio in an electron: its difference, disregarding a π√(2) factor, is only 0.2%. This is not a coincidence, it is always the same particle and the small difference is between a rotating and a non-rotating particle. The determination of its rotational speed yields accurate numbers for many quantities, including the fine structure constant and the electron magnetic moment

Preschool-aged children spend substantial amounts of time engaged in screen-based activities. As parents have considerable control over their child's health behaviours during the younger years, it is important to understand those influences that guide parents' decisions about their child's screen time behaviours. A prospective design with two waves of data collection, 1 week apart, was adopted. Parents (n = 207) completed a Theory of Planned Behaviour (TPB)-based questionnaire, with the addition of parental role construction (i.e., parents' expectations and beliefs of responsibility for their child's behaviour) and past behaviour. A number of underlying beliefs identified in a prior pilot study were also assessed. The model explained 77% (with past behaviour accounting for 5%) of the variance in intention and 50% (with past behaviour accounting for 3%) of the variance in parental decisions to limit child screen time. Attitude, subjective norms, perceived behavioural control, parental role construction, and past behaviour predicted intentions, and intentions and past behaviour predicted follow-up behaviour. Underlying screen time beliefs (e.g., increased parental distress, pressure from friends, inconvenience) were also identified as guiding parents' decisions. Results support the TPB and highlight the importance of beliefs for understanding parental decisions for children's screen time behaviours, as well as the addition of parental role construction. This formative research provides necessary depth of understanding of sedentary lifestyle behaviours in young children which can be adopted in future interventions to test the efficacy of the TPB mechanisms in changing parental behaviour for their child's health. What is already known on this subject? Identifying determinants of child screen time behaviour is vital to the health of young people. Social-cognitive and parental role constructions are key influences of parental decision-making. Little is known about the

AC loss time constant measurements on Nb3Al and NbTi multifilamentary superconductors

International Nuclear Information System (INIS)

Painter, T.A.

1988-03-01

The AC loss time constant is a previously univestigated property of Nb 3 Al, a superconductor which, with recent technological developments, shows some advantages over the more commonly used superconductors, NbTi and Nb 3 Sn. Four Nb 3 Al samples with varying twist pitches and one NbTi sample are inductively measured for their AC loss time constants. The measured time constants are compared to the theoretical time constant limits imposed by the limits of the transverse resistivity found by Carr [5] and to the theoretical time constants found using the Bean Model as well as to each other. The measured time constants of the Nb 3 Al samples fall approximately halfway between the theoretical time constant limits, and the measured time constants of the NbTi sample is close to the theoretical lower time constant limit. The Bean Model adequately accounts for the variance of the permeability of the Nb 3 Al superconductor in a background magnetic field. Finally, the measured time constant values of the Nb 3 Al samples vary approximately according to the square of their twist pitch. (author)

Scalar-tensor cosmology with cosmological constant

Maslanka, K.

1983-01-01

The equations of scalar-tensor theory of gravitation with cosmological constant in the case of homogeneous and isotropic cosmological model can be reduced to dynamical system of three differential equations with unknown functions H=R/R, THETA=phi/phi, S=e/phi. When new variables are introduced the system becomes more symmetrical and cosmological solutions R(t), phi(t), e(t) are found. It is shown that when cosmological constant is introduced large class of solutions which depend also on Dicke-Brans parameter can be obtained. Investigations of these solutions give general limits for cosmological constant and mean density of matter in plane model. (author)

Ames, Kaitlin E; Rennick, Janet E; Baillargeon, Sophie

2011-06-01

The purpose of this study was to explore parents' perception of the parental role in a tertiary care Canadian university affiliated hospital's paediatric intensive care unit (PICU). A descriptive interpretive design was used with a purposive heterogeneous sample to reflect the range of children and parents normally admitted to the PICU. Semi-structured interviews were conducted with seven parents. Interview data were collected and analysed using the constant comparative method. Three main themes emerged: (1) being present and participating in the child's care; (2) forming a partnership of trust with the PICU health care team; and (3) being informed of the child's progress and treatment plan as the person who "knows" the child best. Enhanced understanding of the parental role in the PICU from the perspective of parents can help guide the development of strategies to more effectively support parents and promote parenting during this extremely stressful time.

Karimi, Arizo; Lindahl, Erica; Skogman Thoursie, Peter

2012-01-01

Women account for the majority of parental leave take-up, which is likely one of the major reasons for the gender gap in income and wages. Consequently, many countries exert effort to promote a more gender equal division of parental leave. Indeed, the last decades have seen an increase in fathers' take-up of parental leave benefits, but the gender earnings gap has remained fairly constant. In this paper we re-evaluate the labour supply responses of both mothers and fathers to three major refo...

With the emphasis on the effects of the density-dependent bag constant and the rotation of strange star the limiting mass of strange star is calculated. The obtained results show that the limiting mass and the corresponding radius of strange star increase as the rotation frequency increases, and tend to be lowered when the density-dependent bag constant is considered.

Cooperation between parents and school nurses in primary schools: parents' perceptions.

Mäenpää, Tiina; Astedt-Kurki, Päivi

2008-03-01

Cooperation between pupils' parents and school nurses is an important part of health promotion in primary schools. Developing frank and trusting relationships contributes to easy and uninhibited cooperation. Cooperation between parents and school nurses has not been widely researched internationally. This article reports on parents' views on cooperation with school nurses in primary schools. The study aims at contributing to school nurses' work so that instead of focusing only on the children, family nursing approaches could be improved. Nineteen parents from 13 families from southern Finland were interviewed for the study in 2004. The data were analysed by grounded theory and the constant comparative method was utilized. Six concepts describing parents' views on cooperation were generated on the basis of the data. Cooperation consists of supporting the child's well-being. School nurses take children's and parents' concerns seriously and intervene effectively if the child's health is threatened. School nurses' expertise is not very visible within school communities. Hoping to receive information and desiring parental involvement are important concepts of cooperation with the school nurse. The child's family is not sufficiently known or taken holistically into consideration when the child's health is promoted. Parents are the initiators of cooperation within school health care and parents describe this by the concept of one-sided communication. Parents do not know about school nurses' work and school health services. They would like to be more involved in school nursing activities. When developing children's health services, parents' expertise in their children's well-being should be paid more attention. This study enhances the knowledge of family nursing by describing Finnish parents' perceptions of cooperation with school nurses. The findings facilitate the understanding of cooperation in school health services.

Do parents of adolescents request the same universal parental support as parents of younger children? A random sample of Swedish parents.

Universal parental support intended to enhance parents' capacity for parenting is an important aspect of public health strategies. However, support has mostly been aimed at parents, especially mothers, of younger children. There is a gap in the research concerning parents of adolescents and fathers' interest in parenting support. To investigate and compare the interest in parenting support of parents of adolescents and younger children, potential differences between mothers and fathers, and their knowledge of what is being offered to them already, and to explore their requirements for future universal parental support. Telephone interviews were conducted with a random sample of 1336 parents. Quantitative methods were used to analyze differences between groups and qualitative methods were used to analyze open-ended questions in regard to parents' requirements for future universal parental support. About 82% of the parents of adolescents interviewed think that offering universal parental support is most important during child's adolescence. There is a substantial interest, particularly among mothers, in most forms of support. Despite their interest, parents have limited awareness of the support available. Only 7% knew about the local municipality website, although 70% reported a possible interest in such a website. Similarly, 3% knew that a parent phone line was available to them, while 59% reported a possible interest. It poses a challenge but is nevertheless important for municipalities to develop support targeted at parents of adolescents which is tailored to their needs, and to reach out with information.

Gravitational lensing limits on the cosmological constant in a flat universe

International Nuclear Information System (INIS)

Turner, E.L.

1990-01-01

Inflationary cosmological theories predict, and some more general aesthetic criteria suggest, that the large-scale spatial curvature of the universe k should be accurately zero (i.e., flat), a condition which is satisfied when the universe's present mean density and the value of the cosmological constant Lambda have certain pairs of values. Available data on the frequency of multiple image-lensing of high-redshift quasars by galaxies suggest that the cosmological constant cannot make a dominant contribution to producing a flat universe. In particular, if the mean density of the universe is as small as the baryon density inferred from standard cosmic nucleosynthesis calculations or as determined from typical dynamical studies of galaxies and galaxy clusters, then a value of Lambda large enough to produce a k = 0 universe would result in a substantially higher frequency of multiple-image lensing of quasars than has been observed so far. Shortcomings of the available lens data and uncertainties concerning galaxy properties allow some possibility of escaping this conclusion, but systematic searches for a gravitational lenses and continuing investigations of galaxy mass distributions should soon provide decisive information. It is also noted that nonzero-curvature cosmological models can account for the observed frequency of galaxy-quasar lens systems and for a variety of other constraints. 61 refs

Choi, Heeseung; Kim, Minju; Park, Chang Gi; Dancy, Barbara L

2012-09-01

This cross-sectional correlational study examined the association between Korean American adolescents' and their parents' reports of parent-child relationships. A total of 61 Korean American families completed a questionnaire assessing parental knowledge, parental/filial self-efficacy, parent-child communication, and parent-child conflicts. T tests, Pearson's correlations, a scatter diagram, and bivariate regression were used to analyze the data. Both Korean American adolescents and their parents reported that fathers were less knowledgeable about their child's school life and less likely to communicate with their children than were mothers. Fathers reported a significantly lower level of parental self-efficacy than mothers, and adolescents also reported a significantly higher level of filial self-efficacy in mother-child relationships than in father-child relationships. Positive correlations between parents' and adolescents' reports of parent-child relationships were observed. These findings indicated a need for parent education programs or counseling services for Korean American parents of adolescents, particularly fathers with inadequate parental skills and limited communication with their children.

A Randomized Controlled Trial Testing the Efficacy of the Creating Opportunities for Parent Empowerment Program for Parents of Children With Epilepsy and Other Chronic Neurological Conditions.

Duffy, Lisa V; Vessey, Judith A

Parents of children with epilepsy and other neurological conditions live with a feeling of constant uncertainty. The uncertainty associated with caring for a child with a neurological condition produces stress, which leads to decreased parental belief in caregiving skills, anxiety, and depression, ultimately altering parental functioning resulting in an increase in child behavioral problems. The stress associated with caring for children with neurological conditions is unlike caring for children with other chronic conditions. Neurological conditions are unpredictable, and there are often no warning signs before an acute event. This unpredictability accompanied with stigma results in social isolation and impacts family functioning. In addition, children with neurological conditions have a higher rate of psychological comorbidities and behavior problems when compared with children with other chronic conditions. This produces an additional burden on the parents and family. This randomized controlled trial tested the efficacy of the Creating Opportunities for Parent Empowerment intervention for parents of children with epilepsy and other neurological conditions. This intervention was administered at three intervals: (a) during hospital admission, (b) 3 days after hospital discharge by telephone, and (c) 4-6 weeks after hospital discharge. Forty-six parents of children admitted to the inpatient neuroscience unit at Boston Children's Hospital participated in the study. Several study limitations resulted in an inadequate sample size to obtain the power necessary to reach statistically significant results for most of the research questions. A one-between, one-within multivariate analysis of variance revealed that the main effect of time was significant for differences in state anxiety for both the usual care group and the intervention group, F(1, 20) = 9.86, p = .005, indicating that state anxiety for both groups combined was more pronounced during the hospitalization.

Coupling constants deduced for the resonances in kaon photo-production

International Nuclear Information System (INIS)

Cheoun, M. K.; Kim, K. S.; Choi, T. K.

2004-01-01

We deduced the coupling constants of nucleon and hyperon resonances, which participate in kaon productions as intermediate states that are formed by electro-magnetic probes and that finally decay into hadronic final states. We used an isobaric model based on an effective Lagrangian approach to describe the processes, in which relevant coupling constants regarding related resonances are effectively determined by fitting available experimental data. Our scheme to deduce the coupling constants was as follows: First, we calculated the lower and the upper limits on the coupling constants by using the experimental decay data available until now and/or theoretical predictions, such as those from quark models and SU(3) symmetry. Second, we exploited those limits as physical constraints on our fitting scheme for the kaon photo-production data. Finally, the deduced values and regions of the coupling constants, which satisfy not only the reaction data but also the decay data, are presented as figures with respect to the strong and the electro-magnetic coupling constants, and their multiplicative values. Our results for the coupling constants give physical values that are more restricted than those allowed by the experimental data nowadays.

2017-04-01

Long-term care (LTC) poses a significant strain on public health insurance financing. In response, there is policy interest in bolstering the private long-term care insurance (LTCI) market. Although families are central to LTC provision, their role in LTCI demand remains unclear. The purpose of this study was to obtain in-depth information concerning: (a) How do older parents evaluate the need for LTCI, (b) what role do adult children play? and (c) How do families communicate about parents' LTC preferences and plans, including LTCI purchase? We conducted focus groups with older parents and adult children in diverse markets. Two groups were conducted with older parents who had purchased LTCI and two with parents who had not purchased LTCI. Four groups were conducted with adult children, mixed as to whether their parents had purchased LTCI. Probes were informed by published reasons for purchasing or not purchasing LTCI. We analyzed transcriptions using directed content analysis and constant comparative method. Older parents valued autonomy for themselves and their children. Older parent purchasers regarded LTCI as supporting this value while nonpurchasers perceived limitations. Adult children described unstated expectations that they would care for their parents. Though discussions between parents and children about LTCI were rare, successful influence occurred when children appealed to shared values, specifically avoiding burden and remaining home. Messages that emphasize autonomy over LTC decisions and interventions that start the LTC conversation among families, with attention to shared values, could increase private LTCI uptake. © The Author 2014.

Radionuclide mass transfer rates from a pinhole in a waste container for an inventory-limited and a constant concentration source

1996-03-01

Analytical solutions for transient and steady state diffusive mass transfer rates from a pinhole in a waste container are developed for constant concentration and inventory-limited source conditions. Mass transport in three media are considered, inside the pinhole (medium 2), outside the container (medium 3) and inside the container (medium 1). Simple equations are developed for radionuclide mass transfer rates from a pinhole. It is shown that the medium with the largest mass transfer resistance need only be considered to provide a conservative estimate of mass transfer rates. (author) 11 refs., 3 figs

When it is costly to have a caring mother: food limitation erases the benefits of parental care in earwigs.

Science.gov (United States)

Meunier, Joël; Kölliker, Mathias

2012-08-23

The aggregation of parents with offspring is generally associated with different forms of care that improve offspring survival at potential costs to parents. Under poor environments, the limited amount of resources available can increase the level of competition among family members and consequently lead to adaptive changes in parental investment. However, it remains unclear as to what extent such changes modify offspring fitness, particularly when offspring can survive without parents such as in the European earwig, Forficula auricularia. Here, we show that under food restriction, earwig maternal presence decreased offspring survival until adulthood by 43 per cent. This effect was independent of sibling competition and was expressed after separation from the female, indicating lasting detrimental effects. The reduced benefits of maternal presence on offspring survival were not associated with higher investment in future reproduction, suggesting a condition-dependent effect of food restriction on mothers and local mother-offspring competition for food. Overall, these findings demonstrate for the first time a long-term negative effect of maternal presence on offspring survival in a species with maternal care, and highlight the importance of food availability in the early evolution of family life.

Elevated CO2 has been reported to stimulate plant growth under nitrogen-sufficient conditions, but the effects of CO2 on growth in a constantly nitrogen-limited state, which is relevant to most natural habitats of plants, remain unclear. Here, we maintained Arabidopsis seedlings under such conditions by growing a mutant with reduced nitrate uptake activity on a medium containing nitrate as the sole nitrogen source. Under nitrogen-sufficient conditions (i.e. in the presence of ammonium), growth of shoots and roots of both the wild type (WT) and the mutant was increased approximately 2-fold by elevated CO2. Growth stimulation of shoots and roots by elevated CO2 was observed in the WT growing with nitrate as the sole nitrogen source, but in the mutant grown with nitrate, the high-CO2 conditions stimulated only the growth of roots. In the mutant, elevated CO2 caused well-known symptoms of nitrogen-starved plants, including decreased shoot/root ratio, reduced nitrate content and accumulation of anthocyanin, but also had an increased Chl content in the shoot, which was contradictory to the known effect of nitrogen depletion. A high-CO2-responsive change specific to the mutant was not observed in the levels of the major metabolites, although CO2 responses were observed in the WT and the mutant. These results indicated that elevated CO2 causes nitrogen limitation in the seedlings grown with a constantly limited supply of nitrogen, but the Chl content and the root biomass of the plant increase to enhance the activities of both photosynthesis and nitrogen uptake, while maintaining normal metabolism and response to high CO2.

Loss of incoherence and determination of coupling constants in quantum gravity

International Nuclear Information System (INIS)

Giddings, S.B.; Strominger, A.

1988-01-01

The wave function of an interacting 'family' of one large 'parent' and many Planck-sized 'baby' universes is computed in a semiclassical approximation using an adaptation of Hartle-Hawking initial conditions. A recently discovered gravitational instanton which exists for general relativity coupled to axions is employed. The outcome of a single experiment in the parent universe is in general described by a mixed state, even if the initial state is pure. However, a sequence of measurements rapidly collapses the wave function of the family of universes into one of an infinite number of 'coherent' states for which quantum incoherence is not observed in the parent universe. This provides a concrete illustration of an unexpected phenomena whose existence has been argued for on quite general grounds by Coleman: Quantum incoherence due to information loss to baby universes is not experimentally observable. We further argue that all coupling constants governing dynamics in the parent universe depend on the parameters describing the particular coherent state into which the family wave function collapses. In particular, generically terms that violate any global symmetries will be induced in the effective action for the parent universe. These last results have much broader applicability than our specific model. (orig.)

We present some evidence which supports a surprising physical interpretation of the fundamental constants. First, we relate two of them through the renormalization group. This leaves as many fundamental constants as base units. Second, we introduce and a dimensional system of units without fundamental constants. Third, and most important, we find, while interpreting the units of the a dimensional system, that is all cases accessible to experimentation the fundamental constants indicate either discretization at small values or boundedness at large values of the corresponding physical quantity.

Problems of discipline are common among parents. These may be the results of the parents' pitfalls in disciplining their children. To find out common pitfalls of parents in disciplining their children. Parents of students with ages ranged between 60-72 months old in Bangkok-Noi district, Bangkok, were selected by random sampling. Total number of 1947 children ages between 60-72 months were recruited. Parents of these children were interviewed with a questionnaire designed to probe into problems in child rearing. There hindered and fifty questionnaires were used for data analyses. Parents had high concerns about problems in discipline their children and needed support from professional personnel. They had limited knowledge and possessed lots of wrong attitude towards discipline. Common pitfalls on the topics were problems in, 1) limit setting 2) rewarding and punishment 3) supervision on children watching TV and bedtime routines. Parents of children with ages 60-72 months old in Bangkok-Noi district, Bangkok, had several common pitfalls in disciplining their children, including attitude, knowledge and practice.

The role of Newton's constant in Einstein's gravity

International Nuclear Information System (INIS)

de Alfaro, V.

1983-01-01

The role of the Newton constant in Einstein particle physics is discussed. The troubles paguing the quantum theory of gravity, including the abscence of an effective cosmological constant, are discussed. The Planck length is studied. The key point is that gravity theory is invariant under general coordinate transformations (GCT). The law of transformations of a tensor under GCT, with attention on dilatations, is determined. The results are compared to the case of a conformal invariant theory in a flat space. The fields in the flat limit are redefined under this rule: in the flat limit the kinetic term must be invariant under conformal transformations. The procedure exhibits clearly the fundamental scale invariance of the Einstein theory

Fennell, D C; Fishel, A H

1998-01-01

To examine the effects of a structured, time-limited parent training group on abusive or potentially abusive parents. A pretest-posttest control group design was used with consenting parents (N = 18) to examine the effects of Systematic Training for Effective Parenting (STEP) on abusive parents' perceptions of their children's behaviors and on the parents' potential to physically abuse. The Adlerian Parental Assessment of Child Behavior Scale and the Child Abuse Potential Inventory were used to measure treatment effects. After participating in STEP, abusive parents had significantly more positive perceptions of their children and were significantly less potentially abusive. Using volunteers, the project cost an average of $100 for each parent. The research lends empirical support to individual psychology and family systems theory. Future research is indicated using larger samples to examine lay vs. professional leadership of the groups, as well as comparisons of different parenting programs with abusive parents.

In the first part of the study we have analyzed the rules of jurisdiction by establishing the jurisdiction of the court hearing with an application for parental responsibility, whether there are pending divorce proceeding or not. In the second part of the study, we have limited the analysis to the rules applicable to the law causes that have as object parental authority.

Vanishing cosmological constant in elementary particles theory

Pisano, F.; Tonasse, M.D.

1997-01-01

The quest of a vanishing cosmological constant is considered in the simplest anomaly-free chiral gauge extension of the electroweak standard model where the new physics is limited to a well defined additional flavordynamics above the Fermi scale, namely up to a few TeVs by matching the gauge coupling constants at the electroweak scale, and with an extended Higgs structure. In contrast to the electroweak standard model, it is shown how the extended scalar sector of the theory allows a vanishing or a very small cosmological constant. the details of the cancellation mechanism are presented. At accessible energies the theory is indistinguishable from the standard model of elementary particles and it is in agreement with all existing data. (author). 32 refs

Four-component relativistic calculations of (77)Se-(13)C spin-spin coupling constants have been performed in the series of selenium heterocycles and their parent open-chain selenides. It has been found that relativistic effects play an essential role in the selenium-carbon coupling mechanism and could result in a contribution of as much as 15-25% of the total values of the one-bond selenium-carbon spin-spin coupling constants. In the overall contribution of the relativistic effects to the total values of (1)J(Se,C), the scalar relativistic corrections (negative in sign) by far dominate over the spin-orbit ones (positive in sign), the latter being of less than 5%, as compared to the former (ca 20%). A combination of nonrelativistic second-order polarization propagator approach (CC2) with the four-component relativistic density functional theory scheme is recommended as a versatile tool for the calculation of (1)J(Se,C). Solvent effects in the values of (1)J(Se,C) calculated within the polarizable continuum model for the solvents with different dielectric constants (ε 2.2-78.4) are next to negligible decreasing negative (1)J(Se,C) in absolute value by only about 1 Hz. The use of the locally dense basis set approach applied herewith for the calculation of (77)Se-(13)C spin-spin coupling constants is fully justified resulting in a dramatic decrease in computational cost with only 0.1-0.2-Hz loss of accuracy.

Free energy correlation of rate constants for electron transfer between organic systems in aqueous solutions

Energy Technology Data Exchange (ETDEWEB)

Meisel, D

1975-07-15

Recent experimental data concerning the rate constants for electron transfer reactions of organic systems in aqueous solutions and their equilibrium constants is examined for possible correlation. The data is correlated quite well by the Marcus theory, if a reorganization parameter, lambda, of 18 kcal/mole is used. Assuming that the only contribution to lambda is the free energy of rearrangement of the water molecules, an effective radius of 5 A for the reacting entities is estimated. For the zero free energy change reaction, i.e., electron exchange between a radical ion and its parent molecule, a rate constant of about 5 X 10/sup 7/ M/sup -1/ s/sup -1/ is predicted. (auth)

Quantum symmetry, the cosmological constant and Planck-scale phenomenology

We present a simple algebraic mechanism for the emergence of deformations of Poincare symmetries in the low-energy limit of quantum theories of gravity. The deformations, called κ-Poincare algebras, are parametrized by a dimensional parameter proportional to the Planck mass, and imply modified energy-momentum relations of a type that may be observable in near future experiments. Our analysis assumes that the low energy limit of a quantum theory of gravity must also involve a limit in which the cosmological constant is taken very small with respect to the Planck scale, and makes use of the fact that in some quantum theories of gravity the cosmological constant results in the (anti)de Sitter symmetry algebra being quantum deformed. We show that deformed Poincare symmetries inevitably emerge in the small-cosmological-constant limit of quantum gravity in 2 + 1 dimensions, where geometry does not have local degrees of freedom. In 3 + 1 dimensions we observe that, besides the quantum deformation of the (anti)de Sitter symmetry algebra, one must also take into account that there are local degrees of freedom leading to a renormalization of the generators for energy and momentum of the excitations. At the present level of development of quantum gravity in 3 + 1 dimensions, it is not yet possible to derive this renormalization from first principles, but we establish the conditions needed for the emergence of a deformed low energy limit symmetry algebra also in the case of 3 + 1 dimensions

This study examined if parental TV viewing, parental self-efficacy or access to media equipment were associated with TV viewing among UK preschool-aged children. Data were derived from a cross-sectional survey of 252 parents of 3-5-year-old children. Parents reported child and parent TV viewing and the number of TVs, DVDs, computers, games consoles, hand-held games consoles, music players and laptop computers in the home. Parents also completed scales which assessed their self-efficacy to limit the screen viewing (SV) and promote the physical activity (PA) and their own PA self-efficacy. Analysis indicated that around two thirds of the children spent two or more hours per day watching TV while 75 % of parents watched ≥ 2 h of TV per day. Logistic regression models showed that children who had a parent who watched ≥ 2 h of TV per day were over five times more likely to also watch ≥ 2 h of TV per day. Each unit increase in parental self-efficacy to limit SV was associated with a 77 % reduction in the likelihood that the child watched ≥ 2 h of TV per day. Each additional piece of media equipment in the home was associated with a 28 % increase in the likelihood that parents watched ≥ 2 h of TV per day. Family-based interventions focusing on changing access to home media equipment and building parental self-efficacy to reduce child TV viewing could form part of efforts to reduce TV viewing among preschool children.

Internet plays a huge role in providing information about health care problems. However, it is unknown how parents use and perceive the internet as a source of information and how this influences health care utilisation when it comes to common complaints in infants. The objective was to evaluate the perception parents have on the role of internet in providing health care information on common symptoms in infants and its effects on health care utilisation. A qualitative design was chosen. Parents were recruited from a population-based birth-cohort and selected purposefully. Semi-structured interviews were used to receive information of parents' ideas. Thematic coding and constant comparison were used for interview transcript analysis. Ten parents were interviewed. Parents felt anxious and responsible when their child displayed common symptoms, and appeared to be in need of information. They tried to obtain information from relatives, but more so from the internet, because of its accessibility. Nevertheless, information found on the internet had several limitations, evoked new doubts and insecurity and although parents compared information from multiple sources, only the physician was able to take away the insecurity. The internet did not interfere in the decision to consult the physician. Parents need information about their children's symptoms and the internet is a major resource. However, only physicians could take away their symptom-related doubts and insecurities and internet information did not play a role in parental decision making. Information gathered online may complement the information from physicians, rather than replace it. Key points Internet plays an increasing role in providing health care information but it is unknown how this influences health care utilisation. Our study suggests that: Parents need information about their children's symptoms and the internet is a major resource. However, only physicians could take away their symptom-related doubts

Who's doing the talking? Teacher and parent experiences of parent-teacher conferences

Directory of Open Access Journals (Sweden)

E M Lemmer

2012-01-01

Full Text Available The most common form of direct communication between parents and teachers in schools worldwide is the parent-teacher conference. Purposeful parent-teacher conferences afford the teacher and the parent the opportunity to address a particular topic related to the child, such as academic progress and behaviour. However, teachers are seldom trained to interact with parents, and both parents and teachers often find such encounters stressful and ineffective. This paper investigates parent and teacher perspectives on the parent-teacher conference through a qualitative inquiry. This is framed by the contributions of ecological theorists to home-school communication and an overview of extant themes in the literature. In the present qualitative inquiry, teacher, parent and learner participants were selected by purposeful and snowball sampling and data were gathered by individual and focus group interviews, school visits and the perusal of written parent-teacher conference reports. The findings indicate that parent-teacher conferences are ritualised school events in all types of schools; parents and teachers' expectations of conferences are limited; teachers are not trained to conduct parent-teacher conferences; and conferencesare overwhelmingly directed at problem solution. Parent-teacher conferences are characterised by a client orientation to parents, rather than a partnership orientation to home-school relations.

A systematic review of interventions to promote social support and parenting skills in parents with an intellectual disability.

Wilson, S; McKenzie, K; Quayle, E; Murray, G

2014-01-01

The family support needs of parents with an intellectual disability (ID) are relatively unknown. This paper reviewed two types of intervention for parents with ID: those designed to strengthen social relationships and those teaching parenting skills. A literature search was conducted using electronic databases and a limited number of evaluative studies were found. The evidence for interventions aimed at strengthening social relationships was inconclusive; although positive changes were observed, there were limitations in study design which restricted the generalizability of the results. The evidence for parental skills teaching suggested that behavioural based interventions are more effective than less intensive forms such as lesson booklets and the provision of normal services, although these studies also had limitations. There is a need for further large scale controlled studies in this area to provide clearer evidence and to explore additional factors relating to child, parent and family which may impact on outcomes. © 2013 John Wiley & Sons Ltd.

Non-minimally coupled varying constants quantum cosmologies

International Nuclear Information System (INIS)

Balcerzak, Adam

2015-01-01

We consider gravity theory with varying speed of light and varying gravitational constant. Both constants are represented by non-minimally coupled scalar fields. We examine the cosmological evolution in the near curvature singularity regime. We find that at the curvature singularity the speed of light goes to infinity while the gravitational constant vanishes. This corresponds to the Newton's Mechanics limit represented by one of the vertex of the Bronshtein-Zelmanov-Okun cube [1,2]. The cosmological evolution includes both the pre-big-bang and post-big-bang phases separated by the curvature singularity. We also investigate the quantum counterpart of the considered theory and find the probability of transition of the universe from the collapsing pre-big-bang phase to the expanding post-big-bang phase

Parental language is associated with children's later language development. Parenting programmes, based on social learning theory, enhance a range of parenting behaviours, yet there is limited evidence for their effect on parental language. To assess the benefits of a behavioural-based parenting programme, which features components of language and communication, to enhance parental language. Parents of toddlers, aged 12 to 36 months, were recruited from eight Flying Start early intervention centres across Wales. Participants were randomised 2:1 either to a parenting programme (n = 60) or to a wait-list control group (n = 29). Researchers were blind to participant allocation throughout the trial. Fifteen-minute video-recorded observations of parents and children interacting during free-play, both at a pre-intervention and at 6-month follow-up, provided the data for the study. Five observed measures of parental language were assessed; quantity and variety, encouraging, critical, child-led and parent led interactions. The Incredible Years Parent-Toddler Programme (IYPTP) is a 12-week group-based behavioural intervention that teaches effective relationship and behavioural management skills including social, emotional and persistence coaching to enable parents to better support their children's development. Of 89 dyads that completed pre-intervention assessments 81 (54 intervention and 27 control) met the criteria for the current study. Intention to treat analysis indicated that child-led language interactions significantly benefited from the intervention [regression coefficient (B) = -1.44, 95% confidence intervals (CI) = -2.59 to -0.29, P = 0.015, effect size (ES) = 0.47] and a positive trend for encouraging language in favour of the intervention sample was evident. Per-protocol sample analysis replicated these findings with encouraging language reaching statistical significance (B = 1.07, 95% CI = 0.11 to 2.03, P = 0.03, ES = 0.52). No further benefits were evident

Purpose We examined timing of first voluntary sexual intercourse as a joint function of parental separation during childhood and parental history of alcoholism. Methods Data were drawn from a birth cohort of female like-sex twins (n=569 African Ancestry [AA], n=3415 European or other Ancestry [EA]). Cox proportional hazards regression was conducted predicting age at first sex from dummy variables coding for parental separation and parental alcoholism. Propensity score analysis was also employed comparing intact and separated families, stratified by predicted probability of separation. Results Earlier sex was reported by EA twins from separated and alcoholic families, compared to EA twins from intact nonalcoholic families, with effects most pronounced through age 14. Among AA twins, effects of parental separation and parental alcoholism were largely nonsignificant. Results of propensity score analyses confirmed unique risks from parental separation in EA families, where consistent effects of parental separation were observed across predicted probability of separation. For AA families there was poor matching on risk-factors presumed to predate separation, which limited interpretability of survival-analytic findings. Conclusions In European American families, parental separation during childhood is an important predictor of early-onset sex, beyond parental alcoholism and other correlated risk-factors. To characterize risk for African Americans associated with parental separation, additional research is needed where matching on confounders can be achieved. PMID:25907653

Elastic constants from microscopic strain fluctuations

Sengupta; Nielaba; Rao; Binder

2000-02-01

Fluctuations of the instantaneous local Lagrangian strain epsilon(ij)(r,t), measured with respect to a static "reference" lattice, are used to obtain accurate estimates of the elastic constants of model solids from atomistic computer simulations. The measured strains are systematically coarse-grained by averaging them within subsystems (of size L(b)) of a system (of total size L) in the canonical ensemble. Using a simple finite size scaling theory we predict the behavior of the fluctuations as a function of L(b)/L and extract elastic constants of the system in the thermodynamic limit at nonzero temperature. Our method is simple to implement, efficient, and general enough to be able to handle a wide class of model systems, including those with singular potentials without any essential modification. We illustrate the technique by computing isothermal elastic constants of "hard" and "soft" disk triangular solids in two dimensions from Monte Carlo and molecular dynamics simulations. We compare our results with those from earlier simulations and theory.

Developmental disorders, including intellectual disability and autism spectrum disorders, may limit an individual's capacity to conduct daily activities. The emotional and economic burden on families caring for an individual with a developmental disorder is substantial, and quality of life may be limited by a lack of services. Therefore, finding effective treatments to help this population should be a priority. Recent work has shown parent skills training interventions improve developmental, behavioural and family outcomes. The purpose of this review protocol is to extend previous findings by systematically analysing randomised controlled trials of parent skills training programmes for parents of children with developmental disorders including intellectual disabilities and autism spectrum disorders and use meta-analytic techniques to identify programme components reliably associated with successful outcomes of parent skills training programmes. We will include all studies conducted using randomised control trials designs that compare a group of parents receiving a parent skills training programme to a group of parents in a no-treatment control, waitlist control or treatment as usual comparison group. To locate studies, we will conduct an extensive electronic database search and then use snowball methods, with no limits to publication year or language. We will present a narrative synthesis including visual displays of study effects on child and parental outcomes and conduct a quantitative synthesis of the effects of parent skills training programmes using meta-analytic techniques. No ethical issues are foreseen and ethical approval is not required given this is a protocol for a systematic review. The findings of this study will be disseminated through peer-reviewed publications and international conference presentations. Updates of the review will be conducted, as necessary, to inform and guide practice. PROSPERO (CRD42014006993). Published by the BMJ Publishing

Full Text Available This work aimed to analyse Eucalyptus grandis W.Hill ex Maiden seed behaviour, under controlled deterioration, and to estimate viability equation constants for the species. Seeds were harvested in the growing season of 1999, and the moisture contents were adjusted from 11.3% to a range between 1.2 and 18.1% at 25ºC. The subsamples were sealed into laminate aluminium-foil packets, for storage in incubators at 40, 50 and 65±0.5ºC. The seeds presented orthodox performance, in which the constants for predicting seed longevity of E. grandis were K E = 9.661, C W = 6.467, C H = 0.03498 and C Q = 0.0002330. The usual and inverse relationship between water content and seed longevity was also observed. The lowest moisture content limit for application of the viability equation at 65ºC was 4.9%, estimated under hygroscopic equilibrium with 23% of relative humidity in the storage environment.Este trabalho teve como objetivos verificar o desempenho de sementes de Eucalyptus grandis W.Hill ex Maiden, após a deterioração em condições controladas, e obter as constantes da equação de viabilidade.

Parents' Lived Experiences During Their Children's Radiotherapy.

Gårdling, Jenny; Törnqvist, Erna; Edwinson Månsson, Marie; Hallström, Inger

The aim of radiotherapy is to provide a cure and/or symptomatic relief for children with cancer. Treatment is delivered on a daily basis, 5 days per week, over the course of 5 to 35 days. Many parents find that leaving their children alone during treatment and exposing them to radiation is a challenging experience. To gain an understanding of parents' lived experiences, 10 parents were asked to keep a diary while their children underwent radiotherapy. A descriptive inductive design with a hermeneutic-phenomenological approach was chosen to analyze the diaries. The parents were asked to write down their lived experiences while their children underwent radiotherapy. Daily notes, both short and long, were desirable. The parents described radiotherapy as a balancing act involving a constant attempt to maintain a balance between coercing and protecting their children in order to improve their children's chances of survival. Meanwhile, the parents themselves were struggling with their own despair and feelings of powerlessness. While protecting their children, they experienced a sense of hope and felt that they had gained control. Parents' daily written reflections are important for clinical practice and provide vital knowledge. Parents need support when focusing on coercing and protecting their children and help with information and routines that enable them gain control.

INITIAL VALIDATION OF THE ASSESSMENT OF PARENTING TOOL: A TASK- AND DOMAIN-LEVEL MEASURE OF PARENTING SELF-EFFICACY FOR PARENTS OF INFANTS FROM BIRTH TO 24 MONTHS OF AGE.

Parenting self-efficacy (PSE) includes parents' self-perceptions regarding their capabilities in performing the numerous and changing tasks associated with parenting a specific child (i.e., domain-specific PSE) as well as their self-perceptions in the parenting role overall (i.e., domain-general PSE). Prior literature has demonstrated PSE's relations with numerous constructs significant to mental health and the parent-infant relationship. Prior measures of PSE have been limited by focusing on only domain-specific or domain-general PSE, ignoring the importance of infant development to PSE, and other psychometric limitations. This article presents sound psychometric data for a new measure of PSE, the Assessment of Parenting Tool (APT). The APT includes task-level items on the Domain-Specific subscale (APT-DS) for each age-referenced version of the measure as well as a domain-general subscale that taps overall PSE within the first 24 months' postpartum. Initial construct validity of the measure is established, particularly for parents of infants aged 3 months and older. A stable, three-factor structure for the domain-general subscale includes "coping with being a parent," "attuned parenting," and "self-perceived model parenting." Future directions for the APT, including a revised checklist format for the domain-specific subscale, are included. © 2016 Michigan Association for Infant Mental Health.

There is growing support for the large-scale implementation of parenting programs for the prevention of child behavior disorders and child maltreatment in younger children. However, there is only limited evidence on the efficacy of parenting programs in modifying risk and protective factors relating to adolescent behavior problems. This study examined the efficacy of Group Teen Triple P (GTTP), an eight-session parenting program specifically designed for parents of young adolescents. Seventy-two families with adolescents aged between 12 and 15 years were randomly assigned to either GTTP (n = 35) or a care as usual (CAU) control condition (n = 37). Compared to CAU parents, parents who received GTTP reported significant improvements in parenting practices, parenting confidence, the quality of family relationships, and fewer adolescent problem behaviors at post-intervention. Several of the parent-reported effects were corroborated by reports from adolescents, including decreases in parent-adolescent conflict and increases in parental monitoring. Adolescents whose parents participated in GTTP also reported significantly fewer behavioral problems than adolescents in the CAU condition. Many of these improvements were maintained at 6-month follow-up.

Most studies of the effects of parental religiousness on parenting and child development focus on a particular religion or cultural group, which limits generalizations that can be made about the effects of parental religiousness on family life. We assessed the associations among parental religiousness, parenting, and children's adjustment in a 3-year longitudinal investigation of 1,198 families from nine countries. We included four religions (Catholicism, Protestantism, Buddhism, and Islam) plus unaffiliated parents, two positive (efficacy and warmth) and two negative (control and rejection) parenting practices, and two positive (social competence and school performance) and two negative (internalizing and externalizing) child outcomes. Parents and children were informants. Greater parent religiousness had both positive and negative associations with parenting and child adjustment. Greater parent religiousness when children were age 8 was associated with higher parental efficacy at age 9 and, in turn, children's better social competence and school performance and fewer child internalizing and externalizing problems at age 10. However, greater parent religiousness at age 8 was also associated with more parental control at age 9, which in turn was associated with more child internalizing and externalizing problems at age 10. Parental warmth and rejection had inconsistent relations with parental religiousness and child outcomes depending on the informant. With a few exceptions, similar patterns of results held for all four religions and the unaffiliated, nine sites, mothers and fathers, girls and boys, and controlling for demographic covariates. Parents and children agree that parental religiousness is associated with more controlling parenting and, in turn, increased child problem behaviors. However, children see religiousness as related to parental rejection, whereas parents see religiousness as related to parental efficacy and warmth, which have different

2006-04-01

Previous theorizing by clinical psychologists suggests that adolescent narcissism may be related to parenting practices (Kernberg, 1975; Kohut, 1977). Two studies investigated the relations between parenting dimensions (i.e., warmth, monitoring, and psychological control) and narcissism both with and without removing from narcissism variance associated with trait self-esteem. Two hundred and twenty-two college students (Study 1) and 212 high school students (Study 2) completed the Narcissistic Personality Inventory, a trait self-esteem scale, and standard measures of the three parenting dimensions. Parental warmth was associated positively and monitoring was associated negatively with both types of narcissism. Psychological control was positively associated with narcissism scores from which trait self-esteem variance had been removed. Clinical implications of the findings are discussed, limitations are addressed, and future research directions are suggested.

Parents of children with epilepsy, like parents of children with many other chronic conditions, are faced with a constant feeling of uncertainty about their child's condition. This uncertainty can lead to a decreased ability to cope as evidenced by increased stress levels, negative mood states, and impaired family functioning. Because altered coping in the parent may have a profound negative impact on the child's psychosocial adjustment to living with a chronic condition, it is important to identify ways to facilitate positive coping skills in the parent. The purpose of this review was to critically analyze the existing literature related to the challenges associated with parenting a child who has epilepsy. Interventions geared toward facilitating coping in parents will also be reviewed, and gaps in the literature will be identified. Lastly, future implications for nursing research will be discussed.

To report a grounded theory study to describe the process of parenting young children who have survived hypoplastic left heart syndrome to inform parent-focused interventions. Technological advances in paediatric cardiology worldwide have improved the survival rates for young children with hypoplastic left heart syndrome who undergo staged surgical palliation. These children, however, are at risk for life-threatening complications and parents are charged with the responsibility to monitor their children at home with minimal support and guidance from healthcare professionals once home. A constructivist grounded theory study. The study was conducted in 2006-2008. Participants were 25 parents (15 mothers, 10 fathers) and 28 grandparents (17 grandmothers, 11 grandfathers) of 15 young children (6 months-4·5 years) who had undergone the Sano surgical approach for hypoplastic left heart syndrome. The 53 interviews were digitally recorded, transcribed and analysed using open and focused coding, constant comparative analysis and memoing. A process of Parenting under Pressure emerged that was characterized by four overlapping and re-emerging phases: (1) realizing and adjusting to the inconceivable; (2) growing increasingly attached; (3) watching for and accommodating the unexpected; and (4) encountering new challenges. In-depth understanding of the phases of Parenting under Pressure provides direction for nurses to support parents of children who survive hypoplastic left heart syndrome. Interventions that help carers of children with complex health conditions move through the phases of our Parenting under Pressure process may help them safeguard the survival of their children, and their own survival as parents as they manage multiple demands. © 2012 Blackwell Publishing Ltd.

Sequential Gaussian Simulation (SGS) is a stochastic simulation technique commonly employed for generating realizations of Gaussian random fields. Arguably, the main limitation of this technique is the high computational cost associated with determining the kriging weights. This problem is compounded by the fact that often many realizations are required to allow for an adequate uncertainty assessment. A seemingly simple way to address this problem is to keep the same simulation path for all realizations. This results in identical neighbourhood configurations and hence the kriging weights only need to be determined once and can then be re-used in all subsequent realizations. This approach is generally not recommended because it is expected to result in correlation between the realizations. Here, we challenge this common preconception and make the case for the use of a constant path approach in SGS by systematically evaluating the associated benefits and limitations. We present a detailed implementation, particularly regarding parallelization and memory requirements. Extensive numerical tests demonstrate that using a constant path allows for substantial computational gains with very limited loss of simulation accuracy. This is especially the case for a constant multi-grid path. The computational savings can be used to increase the neighbourhood size, thus allowing for a better reproduction of the spatial statistics. The outcome of this study is a recommendation for an optimal implementation of SGS that maximizes accurate reproduction of the covariance structure as well as computational efficiency.

Parenting a child with complex needs or disabilities is a challenging proposition. This study, which drew upon of the experiences of the parents of 34 children (in 33 families), set out to explore the themes of impact, need for help and support and meaning/sense-making as they were related by parents. Data were collected using semi-structured interviews, and an emerging theoretical framework was validated through the use of a series of mind-maps(®) which were presented to individual parents as the basis for a second round (verificational) interview. Parents were nominated into the study by health care professions who were asked to identify the subject children to one of three separate sub-groups: children with a disability; children with a life-limiting/life-threatening illness or children with a technology dependence. Comparisons were made between the three study sub-groups in order to identify areas of consistency and of inconsistency. A fourth study theme - 'battleground' emerged from entirely within the data set. Sense-making occupied a central position within the overall theoretical framework for the study and parental perception of 'battleground' presented as significant element of parental sense-making, particularly in the context of their relationships with professional staff. © The Author(s) 2012.

Poor sleep quality impairs immune responses and pain tolerance, both key to recovery from acute illness. Hospitalised children and their co-sleeping parents also risk emotional lability and impaired coping skills when sleep-deprived. We aimed to study the experiences of children and parents during hospital admissions. Semi-structured interviews were conducted with parents within a week of their child's discharge. Questions explored parent and child sleep quality, factors contributing to this, perceived impact on day-time functioning and suggested improvements to ward sleep environment. Southampton Children's Hospital, UK. 17 co-sleeping parents of 16 children aged 3-12 years completed interviews. Children admitted for surgical procedures and those with established sleep disorders or nocturnal seizures were excluded. Constant comparative methods identified themes within the data using a grounded theory approach. Parents reported that they, and to a lesser extent their children, experienced reduced sleep quality. Noise and light as well as ward schedules were identified as key factors disrupting sleep. Parents reported that lack of sleep caused difficulties with their own emotional regulation and that of their child, affecting daytime parent-child relationships. Furthermore, they reported a negative impact of sleep deprivation on decision-making about their child's medical care. Parents identified poor sleep in hospital as a significant additional burden to their child's hospital admission. Importantly, they identified potential improvements to the ward sleep environment. Intervention studies that target modifiable, child-centred alterations to night-time ward culture are recommended, focusing on measurable child and parental outcomes.

Mahat, Ganga; Scoloveno, Mary Ann; Scoloveno, Robert

2016-01-01

The purpose of this study was to explore HIV/AIDS knowledge, self-efficacy for sexual risk behaviors, and parental monitoring in a sample of 140 7th and 9th grade adolescents studying in an urban high school in the United States. Further, the study examined differences in HIV/AIDS knowledge, self-efficacy and parental monitoring by grade and gender. This study also investigated the effectiveness of an HIV/AIDS peer education program, Teens for AIDS Prevention (TAP), on improving adolescents' HIV/AIDS knowledge. A quasi-experimental design was used to examine effects of the peer education program (TAP) on adolescents' HIV/AIDS knowledge. Pearson-product-moment correlation coefficients were calculated to examine the relationships among the variables. Independent t-tests were used to compare adolescents' HIV/AIDS knowledge, self-efficacy, and parental monitoring scores by grade and gender. Paired t-tests were used to determine differences in pre-intervention and post-intervention HIV/AIDS knowledge. The results showed that HIV/AIDS knowledge improved significantly in both 7th and 9th grade students after the intervention. HIV/AIDS knowledge was associated with self-efficacy; however it was not associated with parental monitoring. There were no significant differences in HIV/AIDS knowledge and self-efficacy by gender. However, there was a significant difference in parental monitoring by gender. Pediatric nurses are well-positioned to develop and implement evidence-based programs for adolescents. It is essential that pediatric nurses, in conjunction with other professionals and parent groups, take the initiative in implementing peer education programs in schools and community centers to promote healthy behaviors among adolescents.

Good parent-child communication is thought to help families adjust more easily during stressful events such as parental cancer. Families dealing with cancer who communicate openly have reported less psychological distress. The first year after diagnosis may be particularly stressful. The authors investigated parents' quality of life (QOL) and stress-response symptoms and parent-child communication during the first year after diagnosis and examined possible relationships between communication and parents' functioning. Recently-diagnosed cancer patients (N=70) and spouses (N=55) participated within 4 months of diagnosis (T1) and 6 months (T2) and 12 months later (T3). Parents reported on communication with the children (PACS) and on their own physical and psychosocial functioning (RAND-36) and stress-response symptoms (IES). Parent-child communication remained stable throughout the first year after diagnosis and was similar to communication in families 1 year to 5 years after diagnosis. Patients' functioning improved and cancer-related distress decreased significantly. Spouses' cancer-related distress decreased; their functioning fluctuated through the year. In concurrent analyses, patients' open communication with the children related only to T1 intrusion. Spouses' open communication related to T3 psychosocial functioning; problem communication related to T1 and T2 psychosocial functioning and T2 avoidance. In prospective analyses, no significant relationships were found between parent-child communication and change in parents' functioning. Communication between parents and children remained stable over time; patients' and spouses' functioning improved. Parent-child communication seems to have a limited affect on parents' functioning.

Parent-focused Redesign for Encounters, Newborns to Toddlers (PARENT), is a well-child care (WCC) model that has demonstrated effectiveness in improving the receipt of comprehensive WCC services and reducing emergency department utilization for children aged 0 to 3 in low-income communities. PARENT relies on a health educator ("parent coach") to provide WCC services; it utilizes a Web-based previsit prioritization/screening tool (Well-Visit Planner) and an automated text message reminder/education service. We sought to assess intervention feasibility and acceptability among PARENT trial intervention participants. Intervention parents completed a survey after a 12-month study period; a 26% random sample of them were invited to participate in a qualitative interview. Interviews were recorded, transcribed, and analyzed using the constant comparative method of qualitative analysis; survey responses were analyzed using bivariate methods. A total of 115 intervention participants completed the 12-month survey; 30 completed a qualitative interview. Nearly all intervention participants reported meeting with the coach, found her helpful, and would recommend continuing coach-led well visits (97-99%). Parents built trusting relationships with the coach and viewed her as a distinct and important part of their WCC team. They reported that PARENT well visits more efficiently used in-clinic time and were comprehensive and family centered. Most used the Well-Visit Planner (87%), and found it easy to use (94%); a minority completed it at home before the visit (18%). Sixty-two percent reported using the text message service; most reported it as a helpful source of new information and a reinforcement of information discussed during visits. A parent coach-led intervention for WCC for young children is a model of WCC delivery that is both acceptable and feasible to parents in a low-income urban population.

Parents' and Children's Perspectives of Parental Mediation Strategies in Association with Children's Internet Skills The purpose of this study was to examine the association of parental mediation strategies (from parents' and children's perspective) and children's internet skills. In total 194 parent-child dyads were questioned about their parent's mediation strategies. The children (fifth to ninth grade) additionally answered questions about their internet skills and the amount of time they spent daily on the internet. Parents' and children's ratings of the parental mediation strategies showed moderate associations. Parents reported to use more often mediation strategies than was perceived by their children. The mediation strategies had only limited value for the prediction of the children's internet skills. Parents' and children's perspective about restrictive content mediation were both negatively associated to children's internet skills. After controlling for children's age, sex and time spent daily on the internet, results showed that only congruencies between children's and parental perspectives regarding the parental restrictive content mediation were associated with decreased technical and social internet skills. Additionally, discrepancies between the children's and parental perspectives regarding the parental use of technical mediation were associated with decreased technical internet skills. Discrepancies regarding the parental mediation strategy monitoring were related to increased information navigation skills.

Cobham, Vanessa E; McDermott, Brett; Haslam, Divna; Sanders, Matthew R

2016-06-01

There is widespread support for the hypothesis that, post-disaster, children's mental health is impacted--at least in part--via the impact on parents, parenting, parent-child interactions, and the family environment. To some degree, the enthusiasm with which this hypothesis is held outstrips the evidence examining it. The current paper critically evaluates the empirical evidence for this hypothesis and concludes that although limited (both in terms of number of existing studies and methodological flaws), the extant literature indicates some parent-related variables, as well as some aspects of the family environment are likely to constitute risk or protective factors for children. Given that parenting is modifiable, it is proposed that the identified parent- and family-related factors represent important therapeutic targets, and a universal post-disaster parenting intervention (Disaster Recovery Triple P) is described.

Psychosocial Implications of DSD Treatment for Parents

Wisniewski, Amy B.

2017-01-01

Purpose of the review Historically, studies of caregivers of children with DSD have been limited. Recent findings Recent data reveal that parents of young children with DSD report increased stress, anxiety, depression and decreased quality of life (QoL) in ways that are similar to parents of children with other types of chronic illnesses. Also similar to other chronic illnesses of childhood, parents of children with DSD exhibit overprotective parenting and perceive their child as being vulnerable. These emotions and behaviors exhibited by parents are concerning as they may limit an affected child’s emotional and social development over time. Perhaps more unique to the situation of DSD is the perceived, or real, child-focused stigma experienced by parents of children with DSD. Summary Interventions to improve parents’ psychosocial adaptation to their child’s medical condition, including coaching in how to discuss their child’s condition in a manner that makes them feel safe and supported, are needed to optimize outcomes for families.

Due to high cervical cancer rates and limited research on human papillomavirus (HPV) vaccine acceptability in India, the research team examined parental attitudes toward HPV vaccines. Thirty-six interviews with parents were conducted to assess sexually transmitted infection (STI)-related knowledge and HPV-specific vaccine awareness and acceptability. Despite limited knowledge, parents had positive views toward HPV vaccines. Common barriers included concerns about side effects, vaccine cost, and missing work to receive the vaccine. Parents were strongly influenced by health care providers' recommendations. Our findings suggest that addressing parental concerns, health worker training and polices, and efforts to minimize cost will be central to successful HPV vaccine implementation.

Violent media exposure has been associated with aggressive behavior, and it has been suggested that child health professionals counsel families on limiting exposure. Effective violence prevention counseling requires an understanding of norms regarding parental attitudes, practices, and influencing factors. Both theories of reasoned action and planned behavior emphasize that subjective norms and attitudes affect people's perceptions and intended behavior. Few data exist on violent television viewing and monitoring from a cross-section of families. By understanding the spectrum of parental attitudes, community-sensitive interventions for violence prevention can be developed. The objective of this study was to assess attitudes about and monitoring of violent television viewing from the perspective of parents. An anonymous self-report assisted survey was administered to a convenience sample of parents/guardians who visited child health providers at 3 sites: an urban children's hospital clinic, an urban managed care clinic, and a suburban private practice. The parent questionnaire included questions on child-rearing attitudes and practices and sociodemographic information. A total of 1004 adults who accompanied children for health visits were recruited for the study; 922 surveys were completed (participation rate: 92%). A total of 830 (90%) respondents were parents and had complete child data. Of the 830 respondents, 677 had questions on television viewing included in the survey and were the focus of this analysis. Seventy-five percent of families reported that their youngest child watched television. Of these, 53% reported always limiting violent television viewing, although 73% believed that their children viewed television violence at least 1 time a week. Among television viewers, 81% reported usually or always limiting viewing of sexual content on television and 45% reported usually or always watching television with their youngest child. Among children who watched

Parenting gifted and talented children: what are the key child behaviour and parenting issues?

Science.gov (United States)

Morawska, Alina; Sanders, Matthew R

2008-09-01

The literature on gifted and talented children is limited. Little is known about the types and nature of difficulties experienced by gifted and talented children, and even less known about parenting issues related to parenting a gifted and talented child. The aim of the present study was to describe children's behavioural and emotional adjustment, and the factors that contribute to children's difficulties, as well as to examine the styles of discipline used by parents of gifted and talented children and their level of confidence in managing specific parenting tasks. A survey of parents of gifted and talented children was conducted, with 211 parents meeting criteria for the study. For a community sample, in general gifted and talented children exhibit no more behavioural difficulties than do other children. But children in this sample seemed to show higher levels of emotional symptoms and peer problems. Children's behavioural and emotional difficulties were best predicted by parenting factors, particularly parental confidence. Parents reported that they were less likely to be permissive with their child, but they tended to use a more authoritarian style of parenting characterized by lecturing and a strong reaction to any problems. There are a number of implications for future research, clinical practice, and the development of parenting interventions for this group of parents.

Pharmacotherapy for parents with attention-deficit hyperactivity disorder (ADHD): impact on maternal ADHD and parenting.

Science.gov (United States)

Chronis-Tuscano, Andrea; Stein, Mark A

2012-09-01

Given the high heritability of the disorder, attention-deficit hyperactivity disorder (ADHD) is common among parents of children with ADHD. Parental ADHD is associated with maladaptive parenting, negative parent-child interaction patterns and a diminished response to behavioural parent training. We describe our previous research demonstrating that stimulant medications for mothers with ADHD are associated with reductions in maternal ADHD symptoms. Although limited beneficial effects on self-reported parenting were also found in our study, the impact of ADHD medications on functional outcomes related to parenting and family interactions may not be sufficient for many families. Many questions remain with regard to how best to treat multiplex ADHD families in which a parent and child have ADHD. In particular, future studies are needed: (1) to evaluate how best to sequence pharmacotherapy, psychosocial treatment for adult ADHD and behavioural parenting interventions; (2) to determine the best approach to maintaining treatment effects over the long term for both parents and children; and (3) to identify individual predictors of treatment response.

High school drinking mediates the relationship between parental monitoring and college drinking: A longitudinal analysis

Directory of Open Access Journals (Sweden)

Vincent Kathryn B

2008-03-01

Full Text Available Abstract Background College drinking is a significant public health problem. Although parental monitoring and supervision reduces the risk for alcohol consumption among younger adolescents, few studies have investigated the impact of earlier parental monitoring on later college drinking. This study examined whether parental monitoring indirectly exerts a protective effect on college drinking by reducing high school alcohol consumption. Methods A longitudinal cohort of 1,253 male and female students, ages 17 to 19, attending a large, public, mid-Atlantic university was studied at two time points. First, data on high school parental monitoring and alcohol consumption were gathered via questionnaire during the summer prior to college entry. Second, during the first year of college, past-year alcohol consumption was measured via a personal interview. Multiple regression models tested the relationship between parental monitoring and past year alcohol use (i.e., number of drinks per drinking day. Results Holding constant demographics, SAT score, and religiosity, parental monitoring had a significant protective effect on both high school and college drinking level. However, the association between parental monitoring and college drinking level became non-significant once high school drinking level was held constant. Conclusion While parental monitoring did not directly influence college alcohol consumption, evidence for mediation was observed, whereby parental monitoring had an indirect influence on college drinking through reductions in high school drinking. Initiatives that promote effective parenting might be an important strategy to curb high-risk drinking among older adolescents. More research is needed to understand the nature and degree of parent-child communication that is necessary to extend the protective influence of parents into the college years.

Any variation of the fundamental physical constants, and more particularly of the fine structure constant, $\\alpha$, or of the mass of the electron, $m_e$, would affect the recombination history of the Universe and cause an imprint on the cosmic microwave background angular power spectra. We show that the Planck data allow one to improve the constraint on the time variation of the fine structure constant at redshift $z\\sim 10^3$ by about a factor of 5 compared to WMAP data, as well as to break the degeneracy with the Hubble constant, $H_0$. In addition to $\\alpha$, we can set a constraint on the variation of the mass of the electron, $m_{\\rm e}$, and on the simultaneous variation of the two constants. We examine in detail the degeneracies between fundamental constants and the cosmological parameters, in order to compare the limits obtained from Planck and WMAP and to determine the constraining power gained by including other cosmological probes. We conclude that independent time variations of the fine structu...

Weak decay constants of light and heavy pseudoscalar mesons

We investigate the weak leptonic decays of light and heavy pseudoscalar mesons in a relativistic quark model of independent quarks. We perform a static calculation of the decay constant f{sub M} purely on grounds of simplicity. In order to minimize the possible uncertainty in the static calculation, we estimate the ratios of the decay constants which are found to be in good agreement, in the heavy flavor sector, with the predictions of other models available in the literature and existing experimental data. However, there is a noticeable discrepancy in the current prediction for pion decay constant which demonstrates the inherent limitations of the static approximation in the study of non-strange light mesons.

Sensitivity of molecular vibrational dynamics to energy exchange rate constants

International Nuclear Information System (INIS)

Billing, G D; Coletti, C; Kurnosov, A K; Napartovich, A P

2003-01-01

The sensitivity of molecular vibrational population dynamics, governing the CO laser operated in fundamental and overtone transitions, to vibration-to-vibration rate constants is investigated. With this aim, three rate constant sets have been used, differing in their completeness (i.e. accounting for single-quantum exchange only, or for multi-quantum exchange with a limited number of rate constants obtained by semiclassical calculations, and, finally, with an exhaustive set of rate constants including asymmetric exchange processes, as well) and in the employed interaction potential. The most complete set among these three is introduced in this paper. An existing earlier kinetic model was updated to include the latter new data. Comparison of data produced by kinetic modelling with the above mentioned sets of rate constants shows that the vibrational distribution function, and, in particular, the CO overtone laser characteristics, are very sensitive to the choice of the model. The most complete model predicts slower evolution of the vibrational distribution, in qualitative agreement with experiments

Introduction Parenting has been shown to affect smoking among children in U.S. majority groups, but less is known about this association among multiethnic urban populations. Our study examines the role of parenting on smoking among a highly diverse sample. Methods Health surveys were collected from eighth graders (N =459) in 2 low-income urban schools. Structural equation models examined the direct and indirect effects of authoritative parenting on lifetime smoking.

Parenting has been shown to affect smoking among children in U.S. majority groups, but less is known about this association among multiethnic urban populations. Our study examines the role of parenting on smoking among a highly diverse sample. Health surveys were collected from eighth graders (N = 459) in 2 low-income urban schools. Structural equation models examined the direct and indirect effects of authoritative parenting on lifetime smoking. A moderated mediation analysis examined whether indirect effects of authoritative parenting vary among racial/ethnic groups. Authoritative controlling parenting, characterized by limit setting, was positively associated with anti-tobacco parenting. Anti-tobacco parenting was inversely associated with smoking, mediating the relationship between controlling parenting and smoking. There was no evidence that mediation was moderated by race/ethnicity. Parent training, which focuses on setting rules and expectations, can be an important and universal element of smoking prevention programs targeted to youth in diverse communities.

Han, Muxin; Huang, Zichang; Zipfel, Antonia

2018-04-01

In recent years, the calculation of the first nonvanishing order of the metric 2-point function or graviton propagator in a semiclassical limit has evolved as a standard test for the credibility of a proposed spin foam model. The existing results of spin foam graviton propagators rely heavily on the so-called double scaling limit where spins j are large and the Barbero-Immirzi parameter γ is small such that the area A ∝j γ is approximately constant. However, it seems that this double scaling limit is bound to break down in models including a cosmological constant. We explore this in detail for the recently proposed model [7 H. M. Haggard, M. Han, W. Kaminski, and A. Riello, Nucl. Phys. B900, 1 (2015), 10.1016/j.nuclphysb.2015.08.023.] by Haggard, Han, Kaminski, and Riello and discuss alternative definitions of a graviton propagator, in which the double scaling limit can be avoided.

Rate constants for the reactions of OH with HFC-134a (CF3CH2F) and HFC-134 (CHF2CHF2)

Science.gov (United States)

Demore, W. B.

1993-01-01

Measurements of rate constants for HFC-134 (CF2HCF2H) relative to CH3CCl3, HFC-125, and HFC-134a are reported. The measurements were made in a slow-flow, temperature controlled photochemical reactor, and were based on relative rates of disappearance of the parent compounds as measured by FTIR spectroscopy. Hydroxyl radicals were generated by 254-nm photolysis of O3 in the presence of water vapor. NASA/JPL rate constants for the reference compounds are used to derive temperature-dependent rate constants of both compounds. Rate constants obtained from the different reference compounds are in excellent agreement. The presently recommended rate constant for HFC-134a is about 25 percent too high.

Classically exact surface diffusion constants at arbitrary temperature

International Nuclear Information System (INIS)

Voter, A.F.; Cohen, J.M.

1989-01-01

An expression is presented for computing the classical diffusion constant of a point defect (e.g., an adatom) in an infinite lattice of binding sites at arbitrary temperature. The transition state theory diffusion constant is simply multiplied by a dynamical correction factor that is computed from short-time classical trajectories initiated at the site boundaries. The time scale limitations of direct molecular dynamics are thus avoided in the low- and middle-temperature regimes. The expression results from taking the time derivative of the particle mean-square displacement in the lattice-discretized coordinate system. Applications are presented for surface diffusion on fcc(100) and fcc(111) Lennard-Jones crystal faces

Incredible parenting with Incredible Years?: A Foucauldian analysis of New Zealand Government Perspectives on Parenting and their Implications for Parents and educators in Early Childhood Education

Full Text Available This paper takes a post-structural approach, examining what and how issues are framed in the parenting policy, Incredible Years, through Foucault’s (1977, 1980, 1991, 2003, 2004 notion of governmentality and discursive normalisation . By unpacking discourses of parenting produced by Incredible Years as an accepted parenting programme, it aims to reveal the norm of parenting that is promoted by the current system, and explores how this concept of truth in parenting influences the everyday life of families. The critical analysis of Incredible Years shows that the programme (reproduces the economic/neoliberal discourses as the normal/desirable norm of parenting, thus maintaining/reinforcing the existing power relations in society. The author argues that this notion of a curriculum for parents provides only a limited understanding of the issue, and intensifies inequality and injustice in the milieu. This paper aims to provide the insights for reconceptualising our understanding of parenting for future policy decisions and effective pedagogy.

Oxidative kinetics of amino acids by peroxydisulfate: Effect of dielectric constant

International Nuclear Information System (INIS)

Khalid, Mohammad A. A.

2008-01-01

The kinetics and mechanism of oxidation of alanine, asparagines, cysteine, glutamic acid, lysine, phenylalanine and serine by peroxydisulfate ion have been studied in aqueous acidic (sulfuric acid) medium at the temperature range 60-80C. The rate shows first order dependence on peroxydisulfate concentration and zero order dependence on amino acid concentration. The rate law observed is: -d [S2O82-] /dt = Kobs [S2O82-] [amino acid]0. An autocatalytic effect has been observed in amino acids oxidation due to formation of Schiff's base between the formed aldehyde and parent amino acid. A decrease in the dielectric constant of the medium-adding acetic acid (5-15% v/v) results in a decrease in the rate in all cases studied. Reactions were carried out at different temperature (60-80C) and the thermodynamics parameters have been calculated. The logarithm of the rate constant is linearly interrelated to the square root of the ionic strength. (author)

Multi-wavelength spectrophotometric determination of acidity constant of some newly synthesized Schiff bases and their QSPR study

Science.gov (United States)

Hemmateenejad, Bahram; Emami, Leila; Sharghi, Hashem

2010-01-01

The acidity constants of some newly synthesized Schiff base derivatives were determined by hard-model based multivariate data analysis of the spectrophotometric data in the course of pH-metric titration in 50% (v/v) methanol-water binary solvent. The employed data analysis method was also able to extract the pure spectra and pH-dependent concentration profiles of the acid-base species. The molecules that possess different substituents (both electron donating and withdrawing) on the ortho-, meta- and para-positions of one of the phenyl ring showed variable acidity constants ranging from 8.77 to 11.07 whereas the parent molecule had an acidity constant of 10.25. To investigate the quantitative effects of changing of substitution pattern on the acidity constant, a quantitative structure-property relation analysis was conducted using substituent constants and molecular descriptor. Some models with high statistical quality (measured by cross-validation Q2) were obtained. It was found that the acidity constant of the studied molecules in the methanol-water mixed solvent not only is affected by electronic features of the solutes but also by the lipophilic interaction between methanol part of solvent and the deprotonated solutes.

Castrucci, Brian C; Gerlach, Karen K

2006-03-01

Research on adolescent cigarette smoking has attempted to measure the role of parents in preventing smoking experimentation and uptake. However, aspects of parental influence have often been limited to parental smoking behavior or antismoking socialization. Only a limited number of studies considered the hypothesis that the influence of parenting on adolescent current cigarette smoking may extend beyond parental behavior and antismoking socialization to consider broader measures of the parent-child relationship, such as parenting style. The sample was nationally representative and included 17,287 high school students nationwide. Data were used to categorize the parenting style--authoritative, permissive, autocratic, and unengaged--experienced by each respondent. Logistic regression analysis was used to assess the association between parenting style and adolescent current cigarette smoking. Authoritative parenting was associated with a reduction in the odds of adolescent current cigarette smoking (OR: 0.74, 99% CI: 0.58, 0.95). When authoritative parenting is simultaneously considered with believing parents' opinions about smoking are important, authoritative parenting was no longer a significant correlate of adolescent current cigarette smoking, while believing parents' opinions about smoking are important was associated with a 45% (99% CI: 0.48, 0.64) reduction in the odds of adolescent current cigarette smoking. Authoritative parenting was associated with a more than three-fold increase (OR: 3.65, 99% CI: 2.87, 4.66) in the odds of believing parents' opinions about smoking are important. Interventions may want to educate parents about authoritative parenting, which includes the importance of having appropriate and routine conversations with their children, requiring chores, and implementing general rules and boundaries.

Riding the rapids: living with autism or disability--an evaluation of a parenting support intervention for parents of disabled children.

Evidence on the effectiveness of interventions to support parents of disabled children to manage their child's behaviour problems is limited. The aim of this study was to evaluate a group-delivered intervention (Riding the Rapids) which was specifically developed for parents of a child with a disability or autistic spectrum condition. This programme has been routinely delivered by a community-based mental health team across an urban, multi-ethnic locality for a number of years. A non-randomised controlled study design comprising an intervention group (n=48) and comparator (no intervention) group (n=28) was used to evaluate the effects of the intervention on child behaviour (Eyberg Child Behaviour Inventory; parent-set goals) and parenting efficacy and satisfaction (Parents Sense of Competence Scale) at post-intervention and six-month follow-up. Data on costs to the service provider of delivering the intervention were also collected. Receipt of the intervention was associated with significant reductions in parent-reported behaviour problems and significant improvements in parenting efficacy and satisfaction. At six-month follow-up, progress towards achieving parent-set child behaviour goals and parenting satisfaction had been maintained. Post hoc analysis suggests parents who do not have English as a first language may not benefit as much as other parents from this intervention. Findings suggest this is a promising intervention for parents of a child with a disability that is likely to be less resource intensive to service providers than individually delivered interventions. Limitations and implications for future research are discussed. Copyright © 2014 Elsevier Ltd. All rights reserved.

To examine whether parenting styles or practices were associated with children's television (TV) viewing. A total of 431 parent-child dyads (10- to 11-year-old children) from Bristol, United Kingdom, were included. Child and parent TV viewing were self-reported and categorized as 4 hours/day. Children reported maternal parenting style (authoritarian, authoritative, or permissive). Child-reported maternal and paternal sedentary restriction scores were combined to create a family-level restriction score. Multinomial logistic regression was used to examine whether child TV viewing was predicted by parenting style or family restriction. A greater proportion of children with permissive mothers watched >4 hours of TV per day, compared with children with authoritarian or authoritative mothers (P = .033). A greater proportion of children for whom both parents demonstrated high restriction watched 4 hours (vs 4 hours of TV per day was 5.2 times higher for children with permissive (versus authoritative) mothers (P = .010). Clinicians need to talk directly with parents about the need to place limitations on children's screen time and to encourage both parents to reinforce restriction messages.

Type 1 diabetes is a lifelong condition for children and their parents, the management for which imposes a vast responsibility. This study explores the mediating factors that affect Iranian parents' coping processes with their children's type 1 diabetes. Research was conducted using the grounded theory method. Participants were selected purposefully, and we continued with theoretical sampling. Constant comparative analysis was used to analyze the data. The mediating factors of the parental coping process with their child's diabetes consist of the child's cooperation, crises and experiences, economic challenges, and parental participation in care. Findings highlight the necessity of well-informed nurses with insightful understanding of the mediating factors in parental coping with juvenile diabetes in order to meet the particular needs of this group.

By considering the nonrelativistic limit of de Sitter geometry one obtains the nonrelativistic space-time with a cosmological constant and Newton Hooke (NH) symmetries. We show that the NH symmetry algebra can be enlarged by the addition of the constant acceleration generators and endowed with central extensions (one in any dimension (D) and three in D=(2+1)). We present a classical Lagrangian and Hamiltonian framework for constructing models quasi-invariant under enlarged NH symmetries that depend on three parameters described by three nonvanishing central charges. The Hamiltonian dynamics then splits into external and internal sectors with new noncommutative structures of external and internal phase spaces. We show that in the limit of vanishing cosmological constant the system reduces to the one, which possesses acceleration-enlarged Galilean symmetries.

Barriers to Participation in Parenting Programs: The Relationship between Parenting Stress, Perceived Barriers, and Program Completion.

Families experiencing child maltreatment or risk factors for child maltreatment often receive referrals to interventions focused on changing parenting practices. Compliance with specific parenting programs can be challenging as many of the stressors that place families at-risk may also interfere with program participation. Because families may receive limited benefit from programs they do not fully receive, it is critical to understand the relationship between parenting stress and barriers to program completion. We used structural equation modeling to examine the relationship among parenting stress, perceived barriers to program participation, and program completion in two datasets involving low-income parents. Data were collected at two time points from a sample of parents involved with child welfare services and a sample of parents considered at-risk of future involvement (total study n = 803). Direct paths from parenting stress at time 1 to barriers to participation and parenting stress at time 2, and from parenting stress at time 2 to program completion were significant. Interestingly, increased barriers to participation were related to increased parenting stress at time 2, and greater parenting stress was related to increased program completion. Results suggest that with increasing levels of parenting stress, parents have an increased likelihood of completing the program. Assessing and addressing the influence of perceived barriers and parenting stress on program participation may decrease the likelihood of treatment attrition.

The extent to which selected aspects of family health potential (strengths, motivation, and resources) predicted health work (health-related problem-solving and goal attainment behaviors) was examined in a Canadian sample of 138 female-headed single-parent families and two-parent families. The mother and one child (age 10-14) each completed mailed self-report instruments to assess the independent variables of family cohesion, family pride, mother's non-traditional sex role orientation, general self-efficacy, internal health locus of control, network support, community support, and family income, as well as the dependent variable, health work. With the effects of mothers' education held constant, the independent variables predicted 22 to 27% of the variance in health work in the total sample and each family type. Family cohesion was the most consistent predictor of health work, accounting for 8 to 13% of the variance. The findings challenge existing problem-oriented views of single-parent families by focusing on their potential to engage in health promotion behavior.

Using the pulsed-neutron source technique, the diffusion constant was measured in systems with empty channels. Plexiglas was used as the neutron diffusing material. From separate sets of measurements on rectangular blocks the diffusion constants parallel and perpendicular to channels were determined. The average value of the diffusion constant was also obtained experimentally from measurements on cubes. The difference between both diffusion constants, D{sub Double-Up-Tack} - D{sub Up-Tack }, agrees with theoretical predictions inside the limits of experimental errors, yet the average diffusion constant lies systematically below the predictions of Behrens' theory.

The current study employed a quasi-experimental design using both intent-to-treat and protocol adherence analysis of 155 moderate- to high-risk juvenile offenders to evaluate the effectiveness of Parenting with Love and Limits® (PLL), an integrative group and family therapy approach. Youth completing PLL had significantly lower rates of recidivism than the comparison group. Parents also reported statistically significant improvements in youth behavior. Lengths of service were also significantly shorter for the treatment sample than the matched comparison group by an average of 4 months. This study contributes to the literature by suggesting that intensive community-based combined family and group treatment is effective in curbing recidivism among high-risk juveniles. © 2015 Family Process Institute.

Inflation with a smooth constant-roll to constant-roll era transition

Science.gov (United States)

Odintsov, S. D.; Oikonomou, V. K.

2017-07-01

In this paper, we study canonical scalar field models, with a varying second slow-roll parameter, that allow transitions between constant-roll eras. In the models with two constant-roll eras, it is possible to avoid fine-tunings in the initial conditions of the scalar field. We mainly focus on the stability of the resulting solutions, and we also investigate if these solutions are attractors of the cosmological system. We shall calculate the resulting scalar potential and, by using a numerical approach, we examine the stability and attractor properties of the solutions. As we show, the first constant-roll era is dynamically unstable towards linear perturbations, and the cosmological system is driven by the attractor solution to the final constant-roll era. As we demonstrate, it is possible to have a nearly scale-invariant power spectrum of primordial curvature perturbations in some cases; however, this is strongly model dependent and depends on the rate of the final constant-roll era. Finally, we present, in brief, the essential features of a model that allows oscillations between constant-roll eras.

The ratios C 1 /C 2 of the constants defining the equipotential surfaces which describe the external forms of the components of a close binary system have been calculated on the basis of evolutionary models. Theoretical systems have been considered allowing for a wide range of input parameters (masses and separation) and taking into account the evolutionary effects on the radii of the stars during their Main-Sequence lifetime. The systems have not undergone any transfer of matter and are representative of detached binaries with Main-sequence components. The ratios of the constants are confined in limited intervals and, for the highest values of the mass-ratios, they are clustered around the unit. (Auth.)

Charlie Gard and the weight of parental rights to seek experimental treatment.

Science.gov (United States)

Birchley, Giles

2018-05-17

The case of Charlie Gard, an infant with a genetic illness whose parents sought experimental treatment in the USA, brought important debates about the moral status of parents and children to the public eye. After setting out the facts of the case, this article considers some of these debates through the lens of parental rights. Parental rights are most commonly based on the promotion of a child's welfare; however, in Charlie's case, promotion of Charlie's welfare cannot explain every fact of the case. Indeed, some seem most logically to extend from intrinsic parental rights, that is, parental rights that exist independent of welfare promotion. I observe that a strong claim for intrinsic parental rights can be built on arguments for genetic propriety and children's limited personhood. Critique of these arguments suggests the scope of parental rights remains limited: property rights entail proper use; non-personhood includes only a small cohort of very young or seriously intellectually disabled children and the uniqueness of parental genetic connection is limited. Moreover, there are cogent arguments about parents' competence to make judgements, and public interest arguments against allowing access to experimental treatment. Nevertheless, while arguments based on propriety may raise concerns about the attitude involved in envisioning children as property, I conclude that these arguments do appear to offer a prima facie case for a parental right to seek experimental treatment in certain limited circumstances. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

The inclusion of parents in adolescent-targeted interventions is intended to benefit the adolescent. Limited research has explored whether parents participating in these programs also benefit directly. We examined the impact of Caribbean Informed Parents and Children Together, the parenting portion of an adolescent-targeted HIV prevention intervention, on parent-reported measures. Bahamian parent-youth dyads (N = 1,833) participating in the randomized control trial were assigned to receive one of four conditions. Parents were assessed longitudinally at baseline and 6 and 12 months later. Through 12 months follow-up, parents exposed to Caribbean Informed Parents and Children Together showed higher knowledge of condom use skills, perceptions of improved condom use competence on the part of their youth, and perceived improved parent-child communication about sex-related information. Although youth were the targeted beneficiary, parents also benefited directly from the sexual risk reduction parenting program. Parents demonstrated improved perceptions and knowledge that would enable them to more effectively guide their child and also protect themselves from sexual risk. © 2015 Society for Public Health Education.

A low noise constant current source used for measuring the 1/f noise in disordered systems in ohmic as well as nonohmic regime is described. The source can supply low noise constant current starting from as low as 1 μA to a few tens of milliampere with a high voltage compliance limit of around 20 V. The constant current source has several stages, which can work in a standalone manner or together to supply the desired value of load current. The noise contributed by the current source is very low in the entire current range. The fabrication of a low noise voltage preamplifier modified for bias dependent noise measurements and based on the existing design available in the MAT04 data sheet is also described.

To characterise parent presentations of fussy eating and mealtime interactions at a point of crisis, through analyses of real-time recordings of calls to a parenting helpline. Qualitative analysis included an inductive thematic approach to examine clinical parent presentations of fussy eating and derive underlying themes relating to mealtime interactions. Calls made to the Child Health Line regarding feeding concerns were recorded and transcribed verbatim. From a corpus of 723 calls made during a 4-week period in 2009, twelve were from parents of children aged 6-48 months. Parents of infants (≤12 months, n 6) presented feeding concerns as learning challenges in the process of transitioning from a milk-based to a solid-based diet, while parents of toddlers (13-48 months, n 6) presented emotional accounts of feeding as an intractable problem. Parents presented their child's eating behaviour as a battle (conflict), in which their children's agency over limited intake and variety of foods (child control) was constructed as 'bad' or 'wrong'. Escalating parent anxiety (parent concern) had evoked parent non-responsive feeding practices or provision of foods the child preferred. Real-time descriptions of young children's fussy eating at a time of crisis that initiated parents' call for help have captured the highly charged emotional underpinnings of mealtime interactions associated with fussy eating. Importantly, they show the child's emerging assertion of food autonomy can escalate parents' emotional distress that, in the short term, initiates non-responsive feeding practices. The current study identifies the importance of educational and emotional support for parents across the period of introducing solids.

Validated measures of parental perceived child risk for development of type 2 diabetes mellitus, parental limit setting for sedentary behavior, and parental nurturance were evaluated as predictors of adolescent body mass index. Results. In this cross-sectional study, multiple linear regression demonstrated that parents of adolescents with higher zBMI reported worrying more about their child's risk of developing type 2 diabetes mellitus. Parent limit setting was also a significant predictor of adolescent zBMI. Contrary to expectations, higher levels of nurturance were associated with higher adolescent zBMI. Post hoc analyses revealed a trend towards a significant interaction between nurturance and limit setting, such that high levels of both parental nurturance and limit setting were associated with lower adolescent zBMI. Conclusions. Current findings suggest the importance of authoritative parenting and monitoring of adolescent health behaviors in the treatment of obesity.

Science homework with video directions for parents: The impact on parental involvement and academic achievement

Science.gov (United States)

Hooker, Kathy L.

The benefits of effective parental involvement in education have been well documented and can be far reaching. When educators make an effort to involve families, parental involvement can be even more meaningful. Homework is a commonly practiced and accepted connection between school and home and affords parents many opportunities to interact with their children on educational endeavors. However, parental involvement may be limited because educators do not reach out to parents, parents feel their children do not need their help, or parents are unfamiliar with the content and therefore unable to help. The purpose of this study was too develop and implement a tool to enhance parental involvement and academic achievement of fourth grade science students. The tool used in this study was a weekly science video to be viewed by parents when it accompanied science homework assignments. To begin, the researcher created six science videos for parents to watch that supplemented weekly homework assignments. Consequently, the researcher set up treatment and comparison groups to test the effectiveness of the supplemental videos in terms of parental involvement and academic achievement. A mixed methods approach was used to collect data from parents and students throughout the study. A combination of quantitative and qualitative data was collected throughout this study from both parents and students. Additionally, data was collected from a variety of sources including baseline, midpoint, and endpoint surveys; scores on homework assignments; and focus group interview sessions with parents and students. Data analysis revealed an overall positive impact on parental involvement and academic achievement when the videos were utilized.

A representation of the two-loop contribution to the pion decay constant in SU(3) chiral perturbation theory is presented. The result is analytic up to the contribution of the three (different) mass sunset integrals, for which an expansion in their external momentum has been taken. We also give an analytic expression for the two-loop contribution to the pion mass based on a renormalized representation and in terms of the physical eta mass. We find an expansion of F{sub π} and M{sub π}{sup 2} in the strange-quark mass in the isospin limit, and we perform the matching of the chiral SU(2) and SU(3) low-energy constants. A numerical analysis demonstrates the high accuracy of our representation, and the strong dependence of the pion decay constant upon the values of the low-energy constants, especially in the chiral limit. Finally, we present a simplified representation that is particularly suitable for fitting with available lattice data. (orig.)

The Parental Overprotection Scale: Associations with child and parental anxiety☆

Science.gov (United States)

Clarke, Kiri; Cooper, Peter; Creswell, Cathy

2013-01-01

Background Parental overprotection has commonly been implicated in the development and maintenance of childhood anxiety disorders. Overprotection has been assessed using questionnaire and observational methods interchangeably; however, the extent to which these methods access the same construct has received little attention. Edwards et al. (2008, 2010) developed a promising parent-report measure of overprotection (OP) and reported that, with parents of pre-school children, the measure correlated with observational assessments and predicted changes in child anxiety symptoms. We aimed to validate the use of the OP measure with mothers of children in middle childhood, and examine its association with child and parental anxiety. Methods Mothers of 90 children (60 clinically anxious, 30 non-anxious) aged 7–12 years completed the measure and engaged in a series of mildly stressful tasks with their child. Results The internal reliability of the measure was good and scores correlated significantly with observations of maternal overprotection in a challenging puzzle task. Contrary to expectations, OP was not significantly associated with child anxiety status or symptoms, but was significantly associated with maternal anxiety symptoms. Limitations Participants were predominantly from affluent social groups and of non-minority status. Overprotection is a broad construct, the use of specific sub-dimensions of behavioural constructs may be preferable. Conclusions The findings support the use of the OP measure to assess parental overprotection among 7–12 year-old children; however, they suggest that parental responses may be more closely related to the degree of parental rather than child anxiety.

The actions and behaviors of parents have been identified as key factors that influence a child's participation in physical activity. However, there is limited knowledge of how parents can be supported to embody facilitative roles. This study aimed to explore how an ecological intervention encourages parents of children with disabilities to develop as facilitators, to enable ongoing physical activity participation in a child's local environment. A qualitative design using grounded theory was employed. Forty four parents (26 mothers, 18 fathers) of 31 children with a range of disabilities (mean age 12y 6m (SD 2y 2m); 18 males) partaking in the Local Environment Model intervention at Beitostolen Healthsports Centre in Norway participated in the study. Data were derived from the triangulation of semi-structured interviews and participant observation. Data analysis was an iterative approach of constant comparison, where data collection, memo writing, open, axial and selective coding analysis, were undertaken simultaneously. Findings were consolidated into a model describing the central phenomenon and its relationship to other categories. Thematic concepts uncovered in this study describe a social process of parent learning and empowerment, comprising three primary components; (i) active ingredients of the intervention that enabled learning and empowerment to transpire, (ii) parent learning and empowerment as a process, and (iii) related outcomes. A family-centered approach, encompassing family-to-family support, may enhance physical activity participation outcomes for children and youth with disabilities.

The (φ4)3+1 theory with infinitesimal bare coupling constants

International Nuclear Information System (INIS)

Yotsuyanagi, I.

1987-01-01

We study the (φ 4 ) 3+1 theory by means of a variational method improved with a BCS-type vacuum state. We examine the theory with both negative and positive infinitesimal bare coupling constants, where the theory has been suggested to exist nontrivially and stably in the infinite ultraviolet cutoff limit. When the cutoff is sent to infinity, we find the instability of the vacuum energy at the end point value of the variational parameter in the case of the negative bare coupling constant. For the positive bare coupling constant, we can renormalize the vacuum energy without using the extremal condition with respect to the variational mass parameter. We do not find an instability for the whole range of parameters including the end point. We still have a possibility that the theory with this bare coupling constant is nontrivial and stable.

Apetroaia, Adela; Hill, Claire; Creswell, Cathy

2015-12-01

High levels of parental anxiety are associated with poor treatment outcomes for children with anxiety disorders. Associated parental cognitions and behaviours have been implicated as impediments to successful treatment. We examined the association between parental responsibility beliefs, maternal anxiety and parenting behaviours in the context of childhood anxiety disorders. Anxious and non-anxious mothers of 7-12 year old children with a current anxiety disorder reported their parental responsibility beliefs using a questionnaire measure. Parental behaviours towards their child during a stressor task were measured. Parents with a current anxiety disorder reported a greater sense of responsibility for their child's actions and wellbeing than parents who scored within the normal range for anxiety. Furthermore, higher parental responsibility was associated with more intrusive and less warm behaviours in parent-child interactions and there was an indirect effect between maternal anxiety and maternal intrusive behaviours via parental responsibility beliefs. The sample was limited to a treatment-seeking, relatively high socio-economic population and only mothers were included so replication with more diverse groups is needed. The use of a range of stressor tasks may have allowed for a more comprehensive assessment of parental behaviours. The findings suggest that parental anxiety disorder is associated with an elevated sense of parental responsibility and may promote parental behaviours likely to inhibit optimum child treatment outcomes. Parental responsibility beliefs may therefore be important to target in child anxiety treatments in the context of parental anxiety disorders. Copyright © 2015 The Authors. Published by Elsevier B.V.

Psychosocial implications of disorders of sex development treatment for parents.

Science.gov (United States)

Wisniewski, Amy B

2017-01-01

Historically, studies of caregivers of children with disorders of sex development (DSD) have been limited. Recent data reveal that parents of young children with DSD report increased stress, anxiety, depression, and decreased quality of life in ways that are similar to parents of children with other types of chronic illnesses. Also similar to other chronic illnesses of childhood, parents of children with DSD exhibit overprotective parenting and perceive their child as being vulnerable. These emotions and behaviors exhibited by parents are concerning as they may limit an affected child's emotional and social development over time. Perhaps, more unique to the situation of DSD is the perceived, or real, child-focused stigma experienced by parents of children with DSD. Interventions to improve parents' psychosocial adaptation to their child's medical condition, including coaching in how to discuss their child's condition in a manner that makes them feel safe and supported, are needed to optimize outcomes for families.

Full Text Available Background and Aim: Research indicates that impaired hearing is one of the most stressful disabilities. The parenting stress involved could lead to family malfunction and improper parenting. Therefore, this study aimed to evaluate the effects of positive parenting programs on the parenting stress of mothers with impaired hearing children.Methods: The statistical population comprised mothers of all 7-12-year-old impaired hearing children in Tehran city. Thereafter, using the random sampling method, 24 individuals were shortlisted as research participants and were randomly assigned to two groups: control and experimental. The experimental group was trained with a positive parenting program based on the Sanders program (1993 over eight sessions. The measurement instrument was the Abidin parenting stress questionnaire.Results: The mean score for grades in the experimental groups’ parent and child domains at the pre- and post-test stages had reduced more than that in the control group. In addition, the results of a multivariate covariance analysis indicated that positive parenting training was effective in the reduction of parenting stress scores, reinforcement, and child mood components in the child domain, and in the feelings of competence, relationships with the spouse, and role limitation components (p<0.05 in the parent domain.Conclusion : Considering the benefits of training parents for the reduction of parenting stress of mothers with impaired hearing children, this method is recommended in all learning centers for the deaf.

Language is an important aspect of health literacy and plays a vital role in families' ability to access and use health information and resources. Our study explored the role of communication and language in the healthcare experiences of immigrant parents of children with cancer living in Canada. We used a grounded theory approach. Chinese and South Asian parents of children 6 months post-diagnosis were recruited from six Canadian pediatric oncology centers. Semi-structured interviews were conducted in Cantonese, Mandarin, Hindi, Punjabi, Urdu, or English. Questions relevant to communication included: how parents navigated the healthcare system; nature of interpreter services and translated materials; and suggestions about how to improve services. Analysis involved line-by-line, focused and theoretical coding, and constant comparison. Thirty-one (62%) parents reported no difficulty communicating with healthcare providers in English, while 13 (26%) parents struggled with English, and six (12%) parents could not communicate in English. Communication challenges influenced parents' role in caring for their child and made it difficult to learn complex medical terminology. Interpreting services were sometimes inadequate or not accessible. Parents occasionally missed out on services and resources, reported limited availability of linguistically and culturally appropriate information, and experienced a lack of social integration in the healthcare process. Language ability played an essential role in parents' healthcare experiences for pragmatic and social purposes. Language challenges can heighten systemic and socio-cultural barriers to accessing health information and resources. The provision of enhanced culturally and linguistically sensitive services may support immigrant families in their caregiving role. Copyright © 2011 Wiley Periodicals, Inc.

Evidence-based pain-limiting strategies for pediatric immunizations remain underutilized, with barriers identified to date mostly pertaining to health care providers and systems of care. The present study sought to quantify and investigate parent attitudes toward pain management as another potential barrier to the routine use of pain-mitigating strategies during immunizations. Questionnaires measuring parent attitudes, willingness to pay, and perceived barriers for using pain management for immunizations were completed by 259 parent/guardians of children ages 0 to 5 years attending appointments at an urban primary care clinic in the Midwestern United States. Parent attitudes toward pain management for immunization were relatively normally distributed and varied from strongly positive to negative, with 33% of parents disagreeing that they were concerned about the pain their child may experience and 50% agreeing that there are no lasting negative effects from immunization pain. Negative parent attitudes were associated with willingness to spend less in money or time for pain management and with greater perceived significance of cost, time, and other barriers for using pain-mitigating strategies. Some parents perceive limited value in trying to reduce pain during immunizations such that they may be hesitant to invest much time or effort in interventions. Greater success of translating evidence-based pain management into practice therefore may require accounting for differences in parent attitudes by tailoring educational efforts and pain management options accordingly.

Passing It On: Parent-to-Adult Child Financial Transfers for School and Socioeconomic Attainment

Directory of Open Access Journals (Sweden)

Emily Rauscher

2016-10-01

Full Text Available As wealth inequality increases, the importance of parental financial transfers for socioeconomic attainment may also rise. Using data from the 2013 Panel Study of Income Dynamics Rosters and Transfers Module, this study investigates two questions: how parental financial transfers for education have changed over time, and what the relationship is between these transfers and adult socioeconomic outcomes. Results suggest that transfers for education have increased, have become more commonplace, and have become more dependent on parental wealth over time. Holding constant several individual and parental measures, the relationship between parental transfers for school and adult socioeconomic attainment is positive. This relationship holds when using three-stage least squares models to account for potential endogeneity of financial transfers for school. Overall, results support arguments that parental financial transfers for education facilitate the intergenerational transmission of socioeconomic standing.

In recent times, parents have become increasingly concerned, both subjectively and objectively, about their adolescents' body height/weight growth. Parent-adolescent interactions about this issue and the potential socio-psychological consequences of such interactions should be considered as an important influencing factor on the future of adolescents' sexual and reproductive health. To achieve a greater understanding of such concerns, it is necessary to further elucidate parents' experiences on this topic, so as to expand the existing literature. This study aimed to explain the perceptions of parents' concerns regarding their adolescents' growth characteristics in the socio-cultural context of Iran as a transitional society. This paper is part of a larger qualitative study designed using the Constructivist Grounded Theory Methodology (CGTM). We conducted open-ended intensive interviews with eleven parents individually and recruited them through purposeful and theoretical sampling from a teaching hospital, community, and a primary school in Tehran with theoretical sampling variation in terms of teenagers' age, sex, and birth order, place of residence, parents' occupation and education, and the self-reported socio-economic status. Using the analytical procedures of the CGTM, we performed analyses. In the findings, the concept of 'living with constant sense of uncertainty' emerged from the subcategories including 'feeling existing and potential concern about expected minimum and maximum bio-positions of growth,' 'feeling potential concern about biological health consequences,' 'feeling potential concern about the emergence of early/late maturity signs,' 'feeling potential concern about adolescent's emotional threat,' 'feeling concerned about future employment, education, marriage, and fertility,' and 'feeling potential concern about the society's view'. These findings suggest that parents are living with a constant sense of uncertainty about their teens' growth

The aim of this study was to evaluate the Parents Plus Adolescents Programme (PPAP)-a parent training course specifically targeting parents of young adolescents (aged 11-16 years)-when delivered as a preventative programme in community school settings. A sample of 126 parents (mean age of children = 12.34 years; range = 10-16 years) were randomly assigned to either a treatment (PPAP; n = 82) or a waiting-list control condition (WC; n = 44). Analyses are based on a study-completer sample post-treatment (n = 109 parents: PPAP n = 70; WC n = 39) and sample at 6 month follow up (n = 42 parents). Both post-treatment (between groups) and 6-month follow-up comparisons of study completers (within PPAP group) revealed significant positive effects of the parenting intervention with respect to adolescent behaviour problems and parenting stress. The post treatment comparisons demonstrated large effect sizes on global measures of child difficulties (partial eta squared = 0.15) and self-reported parent stress (partial eta squared = 0.22); there was a moderate effect size on the self-reported parent satisfaction (partial eta squared = 0.13). This study provides preliminary evidence that PPAP may be an effective model of parent-training implemented in a community-based setting. The strengths and limitations of the study are discussed.

Neurobiological basis of parenting disturbance.

Newman, Louise K; Harris, Melissa; Allen, Joanne

2011-02-01

It has been proposed that early attachment relationships shape the structure and reactivity of social brain structures that underlie later social capacities. We provide a review of the literature surrounding the development of neurological regulatory systems during infancy and outline recent research suggesting these systems go on to underlie adaptive parental responses. We review evidence in the peer-reviewed psychiatric literature including (i) observational human literature on the neurobiological and social sequelae of early parenting experiences, (ii) experimental animal literature on the effects of early maternal care on neurological development, (iii) experimental animal literature on the neurobiological underpinnings of parenting behaviours, (iv) observational and fMRI evidence on the neurobiological correlates of parenting behaviours, (v) functional and volumetric imaging studies on adults affected by borderline personality disorder. The development of infant regulatory systems is influenced by early parenting experiences. These frontolimbic regulatory systems are also heavily implicated in normal parental responses to infant cues. These frontolimbic disturbances are also observed in studies of borderline personality disorder; a disorder associated with poor emotional regulation, early trauma and disturbed parenting. While the current literature is limited to animal models of abnormal care giving, existing disorders associated with deficits in regulatory capacity and abnormal frontolimbic functioning may yet provide a human model of the neurobiology of parenting disturbance.

This article reviews the research literature on links between parental divorce and children's short-term and long-term adjustment. First, I consider evidence regarding how divorce relates to children's externalizing behaviors, internalizing problems, academic achievement, and social relationships. Second, I examine timing of the divorce, demographic characteristics, children's adjustment prior to the divorce, and stigmatization as moderators of the links between divorce and children's adjustment. Third, I examine income, interparental conflict, parenting, and parents well-being as mediators of relations between divorce and children's adjustment. Fourth, I note the caveats and limitations of the research literature. Finally, I consider notable policies related to grounds for divorce, child support, and child custody in light of how they might affect children s adjustment to their parents divorce. © 2009 Association for Psychological Science.

Large Dielectric Constant Enhancement in MXene Percolative Polymer Composites

Tu, Shao Bo

2018-04-06

near the percolation limit of about 15.0 wt % MXene loading, which surpasses all previously reported composites made of carbon-based fillers in the same polymer. With up to 10 wt % MXene loading, the dielectric loss of the MXene/P(VDF-TrFE-CFE) composite indicates only an approximately 5-fold increase (from 0.06 to 0.35), while the dielectric constant increased by 25 times over the same composition range. Furthermore, the ratio of permittivity to loss factor of the MXene-polymer composite is superior to that of all previously reported fillers in this same polymer. The dielectric constant enhancement effect is demonstrated to exist in other polymers as well when loaded with MXene. We show that the dielectric constant enhancement is largely due to the charge accumulation caused by the formation of microscopic dipoles at the surfaces between the MXene sheets and the polymer matrix under an external applied electric field.

Rapid and accurate determination of Stern-Volmer quenching constants

Goodpaster, John V.; McGuffin, Victoria L.

1999-01-01

In this work, a novel system has been designed, characterized, and validated for the determination of fluorescence quenching constants. Capillary flow injection methods are used to automate the preparation and mixing of the fluorophore and quencher solutions. Because of the small diameter of the capillary (75-200 μm), fluorescence measurements can be made without corrections for primary and secondary absorbance effects. The fluorescence spectrometer is equipped with a charge-coupled device (CCD) that has a detection limit of 3.0x10 -9 M (2.3 ppb) and a linear dynamic range of 10 5 for integration times of 0.01-10 s. This spectrometer has a 300 nm spectral range with 1 nm resolution, allowing the fluorescence quenching constants to be calculated at single wavelengths or over integrated wavelength ranges. This system was validated by comparison to traditional methods for the determination of Stern-Volmer constants for alternant and nonalternant polycyclic aromatic hydrocarbons with nitromethane and triethylamine.

Parenting behaviors and childhood experiences have played a central role in theoretical approaches to the etiology of narcissism. Research has suggested an association between parenting and narcissism; however, it has been limited in its examination of different narcissism subtypes and individual differences in parenting behaviors. This study investigates the influence of perceptions of parental invalidation, an important aspect of parenting behavior theoretically associated with narcissism. Correlational and hierarchical regression analyses were conducted using a sample of 442 Australian participants to examine the relationship between invalidating behavior from mothers and fathers, and grandiose and vulnerable narcissism. Results indicate that stronger recollections of invalidating behavior from either mothers or fathers are associated with higher levels of grandiose and vulnerable narcissism when controlling for age, gender, and the related parenting behaviors of rejection, coldness, and overprotection. The lowest levels of narcissism were found in individuals who reported low levels of invalidation in both parents. These findings support the idea that parental invalidation is associated with narcissism.

Research on mindful parenting, an extension of mindfulness to the interpersonal domain of parent-child relationships, has been limited by its reliance on self-report assessment. The current study is the first to examine whether observational indices of parent-youth interactions differentiate between high and low levels of self-reported mindful parenting. The Iowa Family Interaction Rating Scales (IFIRS) were used to code interactions between mothers and their 7th grade youth. Mothers drawn from the top and bottom quartiles (n = 375) of a larger distribution of self-reported interpersonal mindfulness in parenting (N = 804) represented clearly defined high and low mindful parenting groups. Discriminant function analysis (DFA) was used to analyze how well six composite IFIRS observational rating variables (e.g., parental warmth, consistent discipline) discriminated between high and low self-reports of mindful parenting. DFA results were cross-validated, with statistically significant canonical correlations found for both subsamples (p parenting and the observational ratings was also provided through hierarchical regression analyses conducted with a continuous predictor of mindful parenting using the full sample. Thus, the present study provides preliminary evidence for a link between self-reported mindful parenting and observed interactions between parents and youth. PMID:25844494

The transition to parenthood is a period of both joy and challenge for most parents. There is a recognized need to support parents during this period, yet existing interventions have shown limited evidence of efficacy. This study takes a consumer-focused approach to examine the needs and preferences of parents both prenatally (n = 77) and postnatally (n = 123) for parenting support. The study used a cross-sectional design with a purpose-built online survey. Parents were recruited via online forums, Facebook and parenting blogs, childcare centers, and playgroups. In general, all parents were satisfied with their current levels of both formal and informal support, and about one fourth of parents had accessed a parenting intervention. Parents expressed a moderate level of interest in additional parenting information, and parents expecting their first baby indicated preferences for information about basic baby care needs whereas postnatally, parents expressed more interest in topics around self-care and behavior management. The implications for developing interventions and engaging families are discussed. © 2018 Michigan Association for Infant Mental Health.

2013-01-01

Although researchers contend that racial-ethnic minorities experience more stress than whites, knowledge of racial-ethnic disparities in parenting stress is limited. Using a pooled time-series analysis of data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998–99 (n = 11,324), we examine racial-ethnic differences in maternal parenting stress, with a focus on structural and cultural explanations and variations by nativity and child age. In kindergarten, black mothers, albeit U.S.-born only, report more parenting stress than white mothers due to structural disadvantages and authoritarian parenting values. The black-white gap increases from kindergarten to third grade, and in third grade, U.S.-born black mothers’ higher stress than white mothers’ persists after controlling for structural and parenting factors. Hispanic and Asian mothers, albeit foreign-born only, report more stress than white mothers at both ages due to structural disadvantages and authoritarian values. Despite structural disadvantages, American Indian mothers report less stress. PMID:24026535

Parenting Practices that can Prevent or Reduce Childhood Obesity

Directory of Open Access Journals (Sweden)

Galen Eldridge

2011-06-01

Full Text Available Overweight in children is more prevalent than ever before. What can parents do to try to promote health and prevent obesity in their own children? The present paper reviews research related to parenting and childhood obesity. The review describes what food-related parenting practices may be helpful: modeling healthy eating behaviors, making time for family meals, making sure healthy food is available and accessible, becoming aware of appropriate portion sizes, encouraging children to eat breakfast, and limiting soda and fast food intake. The paper also discusses food-related parenting practices that may not work to help prevent obesity: pressure to eat, food rewards, restriction, permissiveness, and modeling of unhealthy eating behaviors. Additional parenting practices such as supporting and engaging in physical activity, encouraging an adequate amount of sleep, and limiting television and other screen-media may also help children to maintain healthy weights. Suggestions are also given for professionals working with youth.

Effective optical constants and effective optical properties of ultrathin trilayer structures

Haija, A.J.; Larry Freeman, W.; Umbel, Rachel

2011-01-01

This work presents an extension of the characteristic effective medium approximation (CEMA) to ultrathin trilayer systems. The extension has been carried out analytically and is supported by corresponding calculations of the effective optical constants of Cu-Au-Cu and Ag-SiO-Ag trilayer systems using the CEMA approximation. This work is in essence a generalization of the characteristic effective medium approximation introduced earlier for ultrathin bilayer structures. This method is used to derive the effective optical constants of a trilayer system, consisting of three thin layers with each constituent layer of thickness much less than the wavelength of the incident radiation. Within this regime a trilayer system is viewed as one effective layer referred to as an effective stack (ES) with well defined effective optical constants, which can be used to calculate the optical properties of the trilayer stack within a specified wavelength range. The CEMA based calculations of the effective optical constants are applied to two trilayer systems with a total of five stacks. Three are Cu-Au-Cu and two are Ag-SiO-Ag stacks. The thicknesses of the parent layers in the Cu-Au-Cu stack range from 3 to 30 nm for Cu and 4 to 40 nm for Au; in the Ag-SiO-Ag stack the constituent layers are 6 nm for Ag, but range from 5 to 10 nm for SiO. This study is for normal or near normal incidence spectroscopy in a wavelength range that extends from visible to near infrared. The agreement between CEMA based ES stack results and those of the standard CMT technique is very satisfactory.

2018-02-01

Parent- and sibling-directed aggression by minor children are two forms of family violence that often co-occur and have strong relations to prior exposure to domestic violence, yet are often overlooked in intervention efforts. In addition, current research does not examine these forms of family violence in tandem, and there is very limited research with samples exposed to domestic violence. To better understand how these forms of aggression operate within a domestic violence context, we interviewed 44 women residing in a domestic violence shelter with at least one child over 3.5 years of age who was aggressive toward them and/or siblings. Caregivers reported on their emotional reactions to children's parent-directed aggression and the types of and effectiveness of help they sought for parent- and/or sibling-directed aggression. In line with previous literature, caregivers endorsed a complex mix of emotional reactions to their children's parent-directed aggression, including anger, sadness, guilt, forgiveness, and worthlessness. In contrast to other studies, most caregivers (89%) had sought help for children's parent- and/or sibling-directed aggression and found it effective. Findings contribute to the literature on parent- and sibling-directed aggression and provide implications for how to effectively intervene.

Colloid-facilitated effects on migration of radionuclides in fractured rock with a kinetic solubility-limited dissolution model

International Nuclear Information System (INIS)

2010-01-01

Nuclides can move with groundwater either as solutes or colloids, where the latter mechanism generally results in much shorter traveling time as the nuclides interact strongly with solid phases, such as actinides. In the performance assessment, it is therefore essential to assess the relative importance of these two transport mechanisms for different nuclides. The relative importance of colloids depends on the nature and concentration of the colloids in groundwater. Plutonium (Pu), neptunium (Np), uranium (U) and americium (Am) are four nuclides of concern for the long-term emplacement of nuclear wastes at potential repository sites. These four actinides have a high potential for migrating if attached to iron oxide, clay or silica colloids in the groundwater.Strong sorption of the actinides by colloids in the groundwater may facilitate the transport of these nuclides along potential flow paths. The solubility-limited dissolution model can be used to assess the safety of the release of nuclear waste in geological disposal sites. Usually, it has been assumed that the solubility of the waste form is constant. If a nuclide reaches its solubility limit at an inner location near the waste form, it is unlikely that the same nuclide will reach its solubility limit at an outer location unless this nuclide has a parent nuclide. It is unlikely that the daughter nuclides will exceed their solubility limit due to decay of their parent nuclide. The present study investigates the effect of colloids on the transport of solubility-limited nuclides under the kinetic solubility-limited dissolution (KSLD) boundary condition in fractured media. The release rate of the nuclides is proportional to the difference between the saturation concentration and the inlet aqueous concentration of the nuclides. The presence of colloids decreases the aqueous concentration of nuclides and, thus, increases the release flux of nuclides from the waste form. (authors)

Communication concerning sexual matters between parents and their adolescent children serve as a protective factor and exerts a favourable influence on adolescents' sexual behaviours. As limited data regarding parent-adolescent sex communication are available in China, this study was undertaken with the aim of exploring the patterns and related factors of such communication and its relationship with adolescent sexual behaviour. Community-based data were collected in 2001 in Changchun, China. Unmarried adolescents 15-19 years of age (322 young men and 360 young women) were included in a survey using self-administered questionnaires. Overall, sex communication with parents was relatively infrequent. There was a significant gender difference in the pattern of sex communication, with male adolescents being more likely to talk with fathers and female adolescents with mothers. Logistic regression analysis revealed that gender of adolescents, quality of communication with mothers on general topics, and adolescent's perception of mother being the main source of sex knowledge were predictive of the level of sex communication between mother and her adolescent children. This study reveals that communication regarding sexual matters between parents and adolescents was limited in China. The quality of communication on general topics between parents and their adolescent children is one of the important factors related to sex communication between them. It is essential that Chinese parents are better informed and skilled to be involved, in addition to school and community, in the sex education of their adolescent children. They should be able to communicate appropriately on sex-related issues with them.

Parental affectionless control and suicidality.

Although poor parental bonding is a known risk factor for suicidality, current literature is inconsistent about the relative role of low parental care and parental overprotection, as well as the combination of the two, termed "affectionless control". This review presents the current state of knowledge of the relationship between suicidality and these two aspects of parental bonding. The computerized databases Medline, PubMed, PsychINFO, PsychLit, and Google Scholar were searched using combinations of the following keywords: suicidality, suicide, suicide attempt, suicidal behavior, parental bonding, and parental bonding instrument. Using the results, we reviewed the reports on the relationship between suicidality and parental bonding as measured by validated parental bonding instruments. Twelve papers were analyzed. All of them used the parental bonding instrument (PBI) and one used both the PBI and the object representation inventory (ORI). Most reports agreed that, in mothers, either lack of maternal care and/or overprotection was associated with an increase in suicidal behavior, while in fathers only low care was consistently associated with suicidality. This lack of constancy with regard to the effect of paternal overprotection appears to be due to cultural differences in fathers' role in child rearing. With these differences acknowledged, affectionless control in both parents emerges as the parenting style most strongly associated with suicidal behavior. Common methodological problems included low numbers of subjects, inconsistent control groups, and the lack of a uniform definition of suicidality. Despite methodological limitations, current literature consistently indicates that parental affectionless control is associated with suicidal behavior. Recognizing affectionless control as a risk factor for suicide and developing early interventions aimed at modifying affectionless and overprotective parenting style in families with a history of affective disorders

Background: This paper aimed to review the literature on the factors associated with parenting stress and resilience among parents of children with autism spectrum disorder (ASD) in the South East Asia (SEA) region. Methods: An extensive search of articles in multiple online databases (PsycNET, ProQuest, PudMed, EMBASE, CINAHL, Web of Science, and Google Scholar) resulted in 28 papers that met the inclusion criteria (i.e., conducted in the SEA region, specific to ASD only, published in a peer-reviewed journal, full text in English). Studies found were conducted in the following countries: Brunei, n = 1; Indonesia, n = 2; Malaysia, n = 12; Philippines, n = 5; Singapore, n = 5, Thailand, n = 2; and Vietnam, n = 1, but none from Cambodia, East Timor, Laos, and Myanmar were identified. Results: Across the studies, six main factors were found to be associated with parenting stress: social support, severity of autism symptoms, financial difficulty, parents' perception and understanding toward ASD, parents' anxiety and worries about their child's future, and religious beliefs. These six factors could also be categorized as either a source of parenting stress or a coping strategy/resilience mechanism that may attenuate parenting stress. Conclusion: The findings suggest that greater support services in Western countries may underlie the cultural differences observed in the SEA region. Limitations in the current review were identified. The limited number of studies yielded from the search suggests a need for expanded research on ASD and parenting stress, coping, and resilience in the SEA region especially in Cambodia, East Timor, Laos, and Myanmar. The identified stress and resilience factors may serve as sociocultural markers for clinicians, psychologists, and other professionals to consider when supporting parents of children with ASD.

Frykedal, Karin Forslund; Rosander, Michael; Barimani, Mia; Berlin, Anita

2018-01-01

The aim of this study was to describe and understand parental group (PG) leaders' experiences of creating conditions for interaction and communication. The data consisted of 10 interviews with 14 leaders. The transcribed interviews were analysed using thematic analysis. The results showed that the leaders' ambition was to create a parent-centred learning environment by establishing conditions for interaction and communication between the parents in the PGs. However, the leaders' experience was that their professional competencies were insufficient and that they lacked pedagogical tools to create constructive group discussions. Nevertheless, they found other ways to facilitate interactive processes. Based on their experience in the PG, the leaders constructed informal socio-emotional roles for themselves (e.g. caring role and personal role) and let their more formal task roles (e.g. professional role, group leader and consulting role) recede into the background, so as to remove the imbalance of power between the leaders and the parents. They believed this would make the parents feel more confident and make it easier for them to start communicating and interacting. This personal approach places them in a vulnerable position in the PG, in which it is easy for them to feel offended by parents' criticism, questioning or silence.

The transport environment presents a unique setting in which the feasibility, advantages, and disadvantages of passengers accompanying a patient must be assessed carefully. The purpose of this study was to describe the current practice of including parents as passengers during pediatric interfacility transport. One-hundred-eighty-eight critical care transport programs in the United States responded to a voluntary mail survey, providing information about current policies, practices, and crew perceptions of the advantages and disadvantages of carrying parents as passengers. Extra seating for passengers was available in 96% of ambulances, 86% of fixed-wing aircraft, and 54% of helicopters used for pediatric transport. Parents traveled as passengers in all types of vehicles; most frequently in ambulances and fixed-wing aircraft. Twenty percent of helicopter programs allowed parent passengers on more than half of their pediatric transports in this vehicle. Advantages of parent passengers included emotional benefit for the parent and child, availability of parents for history and consent, good public relations, and having the parent present if the child dies. Disadvantages included potential parent anxiety, crew distraction, and space limitations. This study reflects the widely diverse policies, practices, and opinions relevant to this topic and confirms a need for further study.

To test the validity and reliability of Brazilian Portuguese version of the Parental-Caregiver Perceptions Questionnaire (P-CPQ) (Aim 1) and to assess the agreement between parents and children concerning the child's oral health-related quality of life (OHRQoL) (Aim 2). The P-CPQ and the Brazilian Portuguese versions of the Child Perceptions Questionnaires (CPQ8-10 and CPQ11-14 ) were used. Objective 1 addressed in the study that involved 210 (validity and internal reliability) and 20 (test-retest reliability) parents and Objective 2 in the study that involved 210 pairs of parents and children. Construct validity was calculated using the Spearman's correlation and the Mann-Whitney/Kruskal-Wallis tests. Reliability was determined using Cronbach's alpha and intraclass correlation coefficient (ICC). Agreement between overall and subscale scores derived from the P-CPQ and CPQ was assessed in comparison and correlation analyses. The P-CPQ discriminated among the categories of malocclusion and dmft. The P-CPQ showed good construct validity, good internal consistency reliability, and excellent test-retest reliability. There was systematic under- and overreporting in parents' assessments for younger and older children, respectively. However, the magnitude of the directional differences was just small. At individual level, agreement between parents and children was excellent. However, it ranged from excellent to moderate or substantial in subscales for CPQ8-10 and CPQ11-14 groups, respectively. The Portuguese version of P-CPQ is valid and reliable. Some parents have limited knowledge about child OHRQoL. Given that parental and child reports measure different realities concerning the child's OHRQoL, information provided by parents can complement the child's evaluation. © 2015 American Association of Public Health Dentistry.

Oral hygiene is a crucial part of caring for young children. This problem is frequently marginalized or even ignored by parents/guardians, what affects child's whole further life. The assessment of parents' knowledge concerning oral hygiene and prevention of dental caries in infants and young children. The test group consisted of parents, as well as men and women currently expecting a child. The study was conducted in a form of a survey, using an original questionnaire, which was carried out in several hospitals in Lodz and online, on a popular local forum for parents. The data obtained were analyzed statistically, allowing the assessment of health awareness of respondents and the creation of various profiles of parental knowledge on the subject investigated. Most of respondents knew the age at which milk and permanent teeth erupt, gave the correct frequency of brushing child's teeth and were in favor of limiting sweets in the diet. A total of 59% correctly gave the number of deciduous teeth and 66% had heard of the "bottle tooth decay". All respondents thought that helping and controlling a child while brushing their teeth is indispensable, but they did not know the best time to start using the toothpaste with fluoride. The information about child's oral hygiene was more often looked for by women (67%) than by men (29%). The study also showed that if a training on the given subject was organized, 60% of respondents would be willing to participate in it. In the test group, pro-health awareness is insufficient to maintain the oral health of the offspring and requires constant developing.

Chronic non-cancer pain (CNCP) is a prevalent occurrence and is experienced by adults in their child-rearing years. Communication within the family about parental illness can be formidable, and family members are often uninformed about illness details. To date, there is no research exploring how children and adolescents understand parental chronic pain, a very complex phenomenon, and its related disability. The aim of this study was to develop a substantive theory that describes how adolescents manage the experience of living with a parent suffering with CNCP and environmental factors that help or hinder this process. Grounded theory was used, the focus of which was adolescents' processes of dealing with parental illness in the interpersonal and environmental contexts of their daily lives. A sample of 30 young adults was recruited in northeastern Ohio using theoretical sampling. During open-ended interviews, participants were asked to look back on their adolescence and talk about how they managed living with parental chronic pain. Interview transcripts and field notes were analyzed using constant comparative methods. Six ways of understanding parental chronic pain emerged from the data: noticing something is different, wrestling with not knowing, searching for answers, questioning the validity of pain, developing insight into the complexity of pain, and learning important life lessons. Findings shed light on how adolescents understand and attach meaning and significance to parental chronic pain and disability and serve as the basis for the development of personalized family interventions.

There is limited research on the links between grandparenting and adolescents' well-being, especially from the perspective of the adolescents. The study examined whether grandparent involvement varied in two-parent biological, lone-parent, and step-families and whether this had a different contribution to the emotional and behavioral adjustment of adolescents across different family structures. The study is based on a sample of 1,515 secondary school students (ages 11-16 years) from England and Wales who completed a structured questionnaire. Findings of hierarchical regression analyses showed that among the whole sample, greater grandparent involvement was associated with fewer emotional problems (p < .01) and with more prosocial behavior (p < .001). In addition, while there were no differences in the level of grandparent involvement across the different family structures, grandparent involvement was more strongly associated with reduced adjustment difficulties among adolescents from lone-parent and step-families than those from two-parent biological families. A possible implication is that the positive role of grandparent involvement in lone-parent and step- families should be more emphasized in family psychology.

The loss of a child is associated with an increased risk for developing psychological problems. However, studies investigating the impact of parents' faith and hope for a cure during the palliative phase on long-term parental psychological functioning are limited. The study's objective was to explore the role of faith and hope as a source of coping and indicator of long-term parental adjustment. Eighty-nine parents of 57 children who died of cancer completed questionnaires retrospectively, exploring faith, hope, and sources of coping, and measuring parents' current level of grief and depression. For 19 parents (21%) faith was very important during the palliative phase. The majority of parents remained hopeful for a meaningful time with their child (n=68, 76%); a pain-free death (n=58, 65%); and a cure (n=30, 34%). Their child (n=70, 79%) was parents' main source of coping. Twelve parents (14%) suffered from traumatic grief, and 22 parents (25%) showed symptoms of depression. Parents' faith was not associated with less long-term traumatic grief (OR=0.86, p=0.51) or symptoms of depression (OR=0.95, p=0.74), and parents' hope for a cure was not related to more long-term traumatic grief (OR=1.07, p=0.71) or symptoms of depression (OR=1.12, p=0.47). Faith was important for a minority of parents and was not associated with less long-term traumatic grief or symptoms of depression. The majority of parents remained hopeful. Hope for a cure was not associated with more long-term traumatic grief or symptoms of depression.

We study constant-roll inflation in the presence of a gauge field coupled to an inflaton. By imposing the constant anisotropy condition, we find new exact anisotropic constant-roll inflationary solutions which include anisotropic power-law inflation as a special case. We also numerically show that the new anisotropic solutions are attractors in the phase space. (orig.)

This distribution exhibits a density profile within the range found in the interstellar medium and an adequate matching of the metric components at its boundary. By identifying this constant curvature with the value of the cosmological constant and superimposing the spherical distributions arising from different matter sources throughout the universe, one is able to mimic a large-scale homogeneous cosmological constant solution.

Parenting Perfectionism and Parental Adjustment

OpenAIRE

Lee, Meghan A.; Schoppe-Sullivan, Sarah J.; Kamp Dush, Claire M.

2012-01-01

The parental role is expected to be one of the most gratifying and rewarding roles in life. As expectations of parenting become ever higher, the implications of parenting perfectionism for parental adjustment warrant investigation. Using longitudinal data from 182 couples, this study examined the associations between societal- and self-oriented parenting perfectionism and new mothers’ and fathers’ parenting self-efficacy, stress, and satisfaction. For mothers, societal-oriented parenting perf...

Technique for determination of the time constant for relay radioisotope instruments

International Nuclear Information System (INIS)

Gol'din, M.L.; Shestialtynov, V.K.

A technique for calculating time constant of a gamma relay used in radio isotope automatics is suggested. It is shown that the time constant of a radioisotope relay device (RRD) mainly depends on parameters of the intergrating circuit ratemeter. Considering the ratemeter as a real communication channel with a limited transmission band, the equation for the active front duration at a ratemeter outlet when applying abrupt voltage to its inlet is obtained. From the complex transmission function of a ratemeter the upper boundary cyclic transmission frequency the substitution of which in the equation of the active front durationg ives the RRD time constant is determined. On the example of calculating the ratemeter for the GR-6 gamma relay a satisfactory coincidence of calculational results with the certificate data is shown [ru

2002-01-01

A detailed study is carried out of the accuracy of molecular equilibrium geometries obtained from least-squares fits involving experimental rotational constants B(0) and sums of ab initio vibration-rotation interaction constants alpha(r)(B). The vibration-rotation interaction constants have been...... calculated for 18 single-configuration dominated molecules containing hydrogen and first-row atoms at various standard levels of ab initio theory. Comparisons with the experimental data and tests for the internal consistency of the calculations show that the equilibrium structures generated using Hartree......-Fock vibration-rotation interaction constants have an accuracy similar to that obtained by a direct minimization of the CCSD(T) energy. The most accurate vibration-rotation interaction constants are those calculated at the CCSD(T)/cc-pVQZ level. The equilibrium bond distances determined from these interaction...

Research has shown that authoritarian parents limit their children's freedom of expression and monitor their children's behavior according to their rules. Children of authoritative families tend to have high self-esteem and refer to internalized norms. Parenting is a cultural product. In this study the model presented is limited in the sense that it does not consider the cultural diversity. We must evaluate the identity not only with perceived parenting style but also within the socio-cultura...

TCP, quantum gravity, the cosmological constant and all that .

International Nuclear Information System (INIS)

Banks, T.

1985-01-01

We study cosmology from the point of view of quantum gravity. Some light is thrown on the nature of time, and it is suggested that the cosmological arrow of time is generated by a spontaneous breakdown of TCP. Conventional cosmological models in which quantum fields interact with a time-dependent gravitational field are shown to describe an approximation to the quantum gravitational wave function which is valid in the long-wavelength limit. Two problems with initial conditions are resolved in models in which a negative bare cosmological constant is cancelled by the classical excitation of a Bose field eta with a very flat potential. These models can also give a natural explanation for the observed value of the cosmological constant. (orig.)

1983-01-01

Stability constants of complexes formed with tetracycline (TC) and uranium have been determined by solvent extraction technique. The site on the tetracycline molecule at which uranyl ion may be bound has been studied by means of potentiometric titration and spectrophotometric techniques. The complex species with 1:1 and 1:2 for UO 2 : TC ratio have been identified by conductometric titration. Solvent extraction studies have also shown that the complexes are mononuclear of the type UO 2 (TC) sub (n) (n=1,2) and that no hidroxocomplexes or negatively charged complexes have been formed. Stability constant values have been calculated by numerical weighted least square method and by graphical methods of two parameters, of the average number of ligands and of the limiting value.

Children of parents with BED have more eating behavior disturbance than children of parents with obesity or healthy weight.

Science.gov (United States)

Lydecker, Janet A; Grilo, Carlos M

2017-06-01

A limited literature suggests an association between parental eating disorders and child eating-disorder behaviors although this research has focused primarily on restrictive-type eating disorders and very little is known about families with binge-eating disorder (BED). The current study focused on parents (N = 331; 103 fathers and 226 mothers), comparing parents with core features of BED (n = 63) to parents with obesity and no eating disorder (OB; n = 85) and parents with healthy-weight and no eating disorder (HW; n = 183). Parents with BED were significantly more likely than OB and HW parents to report child binge eating, and more likely than HW parents to report child overeating. Parents with BED felt greater responsibility for child feeding than OB parents, and felt more concern about their child's weight than OB and HW parents. Dietary restriction of the child by the parents was related to child binge eating, overeating, and child overweight, and parental group was related to child binge eating (parental BED), overeating (parental BED), and child weight (parental OB). Parents with BED report greater disturbance in their children's eating than OB and HW parents, and OB parents report higher child weight than HW parents. This suggests that it is important to consider both eating-disorder psychopathology and obesity in clinical interventions and research. Our cross-sectional findings, which require experimental and prospective confirmations, provide preliminary evidence suggesting potential factors in families with parental BED and obesity to address in treatment and prevention efforts for pediatric eating disorders and obesity. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:648-656). © 2016 Wiley Periodicals, Inc.

Is Asian American Parenting Controlling and Harsh? Empirical Testing of Relationships between Korean American and Western Parenting Measures.

Science.gov (United States)

Choi, Yoonsun; Kim, You Seung; Kim, Su Yeong; Park, Irene Kim

2013-03-01

Asian American parenting is often portrayed as highly controlling and even harsh. This study empirically tested the associations between a set of recently developed Korean ga-jung-kyo-yuk measures and several commonly used Western parenting measures to accurately describe Asian American family processes, specifically those of Korean Americans. The results show a much nuanced and detailed picture of Korean American parenting as a blend of Western authoritative and authoritarian styles with positive and-although very limited-negative parenting. Certain aspects of ga-jung-kyo-yuk are positively associated with authoritative style or authoritarian style, or even with both of them simultaneously. They were positively associated with positive parenting (warmth, acceptance, and communication) but not with harsh parenting (rejection and negative discipline). Exceptions to this general pattern were Korean traditional disciplinary practices and the later age of separate sleeping of children. The study discusses implications of these findings and provides suggestions for future research.

Parents' Executive Functioning and Involvement in Their Child's Education: An Integrated Literature Review.

Science.gov (United States)

Wilson, Damali M; Gross, Deborah

2018-04-01

Parents' involvement in their children's education is integral to academic success. Several education-based organizations have identified recommendations for how parents can best support their children's learning. However, executive functioning (EF), a high-ordered cognitive skill set, contributes to the extent to which parents can follow through with these recommendations. This integrative review of the literature describes how executive function can affect parents' ability to facilitate and actively participate in their child's education and provides strategies for all school staff to strengthen parent-school partnerships when parents have limitations in EF. EF skills are fluid and influenced by several factors, including parental age, sleep, stress, and mood/affect. Despite possible limitations in parental EF, there are strategies school personnel can employ to strengthen partnership with parents to support their children's academic success. As reforms in education call for increased customization and collaboration with families, parental EF is an important consideration for school personnel. Awareness and understanding of how parents' EF affects children's learning will help schools better support parents in supporting their children's academic success. © 2018 The Authors.

'The Unhealthy Other': How vaccine rejecting parents construct the vaccinating mainstream.

Science.gov (United States)

Attwell, Katie; Smith, David T; Ward, Paul R

2018-03-14

To address the phenomenon of vaccine hesitancy and rejection, researchers increasingly recognise the need to engage with the social context of parents' decision-making. This study examines how vaccine rejecting parents socially construct the vaccinating mainstream in opposition to themselves. We analyse qualitative data from interviews with parents in Adelaide, South Australia. Applying insights from Social Identity Theory (SIT), we show how these parents bolster their own sense of identity and self-belief by employing a discourse that casts vaccinators as an Unhealthy Other. We demonstrate how the parents identify vaccination as a marker of parental conformity to the 'toxic practices of mass industrial society', linking it to other ways in which membership of the consumerist mainstream requires individuals to 'neglect their health.' This is explored through themes of appearance, diet, (over) consumption of pharmaceuticals, inadequate parenting values and wilful or misguided ignorance. This construction of the Unhealthy Other elevates the self-concept of vaccine hesitant and rejecting parents, who see themselves as part of an enlightened, but constantly besieged, group of healthy and virtuous parents. It is common for the vaccinating mainstream to present vaccine hesitant and rejecting parents as a group subject to epistemic closure, groupthink, confirmation bias and over-confidence in their own expertise. However, vaccine hesitant and rejecting parents also see mainstream society as a group-a much larger one-subject to the same problems. We suggest the need to mitigate the 'groupness' of vaccination and non-vaccination by extending the practice of vaccination to recognisable practitioners of holistic health.

Running Newton constant, improved gravitational actions, and galaxy rotation curves

International Nuclear Information System (INIS)

Reuter, M.; Weyer, H.

2004-01-01

A renormalization group (RG) improvement of the Einstein-Hilbert action is performed which promotes Newton's constant and the cosmological constant to scalar functions on spacetime. They arise from solutions of an exact RG equation by means of a 'cutoff identification' which associates RG scales to the points of spacetime. The resulting modified Einstein equations for spherically symmetric, static spacetimes are derived and analyzed in detail. The modifications of the Newtonian limit due to the RG evolution are obtained for the general case. As an application, the viability of a scenario is investigated where strong quantum effects in the infrared cause Newton's constant to grow at large (astrophysical) distances. For two specific RG trajectories exact vacuum spacetimes modifying the Schwarzschild metric are obtained by means of a solution-generating Weyl transformation. Their possible relevance to the problem of the observed approximately flat galaxy rotation curves is discussed. It is found that a power law running of Newton's constant with a small exponent of the order 10 -6 would account for their non-Keplerian behavior without having to postulate the presence of any dark matter in the galactic halo

Gender equality and gender differences: parenting, habitus, and embodiment (the 2008 Porter lecture).

Science.gov (United States)

Doucet, Andrea

2009-05-01

Drawing on a four-year research project on Canadian primary caregiving fathers, as well two recent projects on the first year of parenting, this article highlights several theoretical and substantive issues in the study of gender equality and gender differences in parenting. First, I call for shifts from a focus on domestic tasks toward domestic and community-based responsibilities. Second, I argue that the political terrain underpinning the study of mothering and fathering calls for clarity on how researchers interpret the constant interplay between equality and differences. Third, while there has been some change over time, parental responsibilities remain gendered because they are deeply rooted in habitus and embodiment across specific spatial and temporal contexts.

Social Variations in Perceived Parenting Styles among Norwegian Adolescents.

Science.gov (United States)

Elstad, Jon Ivar; Stefansen, Kari

2014-01-01

Previous research has documented the associations between parenting and parenting styles and child and adolescent outcomes. Little is known, however, about the social structuring of parenting in contemporary Nordic welfare states. A possible hypothesis is that socioeconomic variations in parenting styles in present-day Norway will be small because of material affluence, limited income inequality, and an active welfare state. This study examines social variations in parenting as perceived by Norwegian adolescents ( N  = 1362), with a focus on four parenting style dimensions: responsiveness, demandingness, neglecting, and intrusive. Responsiveness seems to capture major divisions in parenting. Adolescents in families with fewer economic resources experienced their parents as somewhat less responsive, but responsiveness was not related to parents' education. Low parental education was on the other hand associated with perceptions of parents as neglecting and intrusive. Viewing parents as demanding did neither vary with parental education nor with family economy. Substantial variations in parenting styles persist in present-day Norway, and these variations correspond moderately with the families' placement in the social structure. Indicators of parenting and parenting styles may be useful indicators of some aspects of child and adolescent well-being.

Noncommuting limits of oscillator wave functions

International Nuclear Information System (INIS)

Daboul, J.; Pogosyan, G. S.; Wolf, K. B.

2007-01-01

Quantum harmonic oscillators with spring constants k > 0 plus constant forces f exhibit rescaled and displaced Hermite-Gaussian wave functions, and discrete, lower bound spectra. We examine their limits when (k, f) → (0, 0) along two different paths. When f → 0 and then k → 0, the contraction is standard: the system becomes free with a double continuous, positive spectrum, and the wave functions limit to plane waves of definite parity. On the other hand, when k → 0 first, the contraction path passes through the free-fall system, with a continuous, nondegenerate, unbounded spectrum and displaced Airy wave functions, while parity is lost. The subsequent f → 0 limit of the nonstandard path shows the dc hysteresis phenomenon of noncommuting contractions: the lost parity reappears as an infinitely oscillating superposition of the two limiting solutions that are related by the symmetry

Two-loop superstrings IV The cosmological constant and modular forms

International Nuclear Information System (INIS)

D'Hoker, E.; Phong, D.H.

2002-01-01

The slice-independent gauge-fixed superstring chiral measure in genus 2 derived in the earlier papers of this series for each spin structure is evaluated explicitly in terms of theta-constants. The slice-independence allows an arbitrary choice of superghost insertion points q 1 ,q 2 in the explicit evaluation, and the most effective one turns out to be the split gauge defined by S δ (q 1 ,q 2 )=0. This results in expressions involving bilinear theta-constants M. The final formula in terms of only theta-constants follows from new identities between M and theta-constants which may be interesting in their own right. The action of the modular group Sp(4,Z) is worked out explicitly for the contribution of each spin structure to the superstring chiral measure. It is found that there is a unique choice of relative phases which insures the modular invariance of the full chiral superstring measure, and hence a unique way of implementing the GSO projection for even spin structure. The resulting cosmological constant vanishes, not by a Riemann identity, but rather by the genus 2 identity expressing any modular form of weight 8 as the square of a modular form of weight 4. The degeneration limits for the contribution of each spin structure are determined, and the divergences, before the GSO projection, are found to be the ones expected on physical grounds

Parents' experiences of their children's presence in discussions with physicians about Leukemia.

2011-05-01

We aimed to examine parents' views regarding their preadolescent child's presence during discussions about serious illnesses. In-depth qualitative interviews with parents of children receiving treatment for acute lymphoblastic leukemia were conducted. Parents were sampled from 6 UK treatment centers. Analysis was informed by the constant comparative method and content analysis. We report on interviews with 53 parents (33 mothers, 20 fathers). Parents acknowledged the benefits of communicating openly with children, but few thought that their child's presence in discussions was straightforwardly desirable. They described how their child's presence restricted their own communication with physicians, made concentrating difficult, and interfered with their efforts to care for their child emotionally. Children's presence was particularly difficult when significant issues were being discussed, including prognoses, adverse results, and certain medical procedures. Parents felt that such discussions posed a potential threat to their child, particularly when they had not first had an opportunity to discuss information with the physician separately from the child. In contrast, separate meetings enabled parents to absorb information and to convey it to their child at an appropriate time and in a reassuring way. Some parents experienced difficulties in accessing separate meetings with physicians. The difficulties parents described could potentially be addressed by extending, beyond the diagnosis period, the practice of sequencing significant information so that it is communicated to parents in separate meetings before being communicated to the child and by periodically exploring with parents what information would be in each child's interests.

Parenting children with down syndrome: An analysis of parenting styles, parenting dimensions, and parental stress.

Science.gov (United States)

Phillips, B Allyson; Conners, Frances; Curtner-Smith, Mary Elizabeth

2017-09-01

Effective parenting is vital for a child's development. Although much work has been conducted on parenting typically developing children, little work has examined parenting children with Down syndrome. The purpose of the current study was to compare the parenting styles and dimensions in mothers of children with DS and mothers of TD children. Thirty-five mothers of children with DS and 47 mothers of TD children completed questionnaires about parenting, parental stress, child behavior problems, and child executive function. We found that mothers of children with DS use an authoritative parenting style less and a permissive parenting style more than mothers of TD children. Additionally, we found that mothers of children with DS use reasoning/induction and verbal hostility less and ignoring misbehavior more than mothers of TD children. All of these differences, except for those of reasoning/induction, were at least partially accounted for by the higher levels of parental stress in the DS group. Parenting interventions should be focused on reducing parental stress and training mothers to parent under stress in an effort to improve parenting techniques, which would, in theory, improve long-term child outcomes for children with DS.

Influence of the cosmological constant on gravitational lensing in small systems

International Nuclear Information System (INIS)

Sereno, Mauro

2008-01-01

The cosmological constant Λ affects gravitational lensing phenomena. The contribution of Λ to the observable angular positions of multiple images and to their amplification and time delay is here computed through a study of the weak deflection limit of the equations of motion in the Schwarzschild-de Sitter metric. Because of Λ the unresolved images are slightly demagnified, the radius of the Einstein ring decreases, and the time delay increases. The effect is however negligible for near lenses. In the case of a null cosmological constant, we provide some updated results on lensing by a Schwarzschild black hole

Welcoming expertise: Bereaved parents' perceptions of the parent-healthcare provider relationship when a critically ill child is admitted to the paediatric intensive care unit.

Science.gov (United States)

Butler, Ashleigh E; Copnell, Beverley; Hall, Helen

2017-11-15

Entering the paediatric intensive care unit with a critically ill child is a stressful experience for parents. In addition to fearing for their child's well-being, parents must navigate both a challenging environment and numerous new relationships with healthcare staff. How parents form relationships with staff and how they perceive both their own and the healthcare providers' roles in this early stage of their paediatric intensive care journey is currently unknown. This paper explores bereaved parents' perceptions of their role and their relationships with healthcare providers when their child is admitted to the intensive care unit, as part of a larger study exploring their experiences when their child dies in intensive care. A constructivist grounded theory approach was utilised to recruit 26 bereaved parents from 4 Australian intensive care units. Parents participated in audio-recorded, semi-structured interviews lasting 90-150min. All data were analysed using the constant comparative analysis processes, supported by theoretical memos. Upon admission, parents viewed healthcare providers as experts, both of their child's medical care and of the hospital system. This expertise was welcomed, with the parent-healthcare provider relationship developing around the child's need for medical care. Parents engaged in 2 key behaviours in their relationships with staff: prioritising survival, and learning 'the system'. Within each of these behaviours are several subcategories, including 'Stepping back', 'Accepting restrictions' and 'Deferring to medical advice'. The relationships between parents and staff shift and change across the child's admission and subsequent death in the paediatric intensive care unit. However, upon admission, this relationship centres around the child's potential survival and their need for medical care, and the parent's recognition of the healthcare staff as experts of both the child's care and the hospital system.

Stiffness-constant variation in nickel-based alloys: Experiment and theory

International Nuclear Information System (INIS)

Hennion, M.; Hennion, B.

1979-01-01

Recent measurements of the spin-wave stiffness constant in several nickel alloys at various concentrations are interpreted within a random-phase approximation, coherent-potential approximation (RPA-CPA) band model which uses the Hartree-Fock approximation to treat the intraatomic correlations. We give a theoretical description of the possible impurity states in the Hartree-Fock approximation. This allows the determination of the Hartree-Fock solutions which can account for the stiffness-constant behavior and the magnetic moment on the impurity for all the investigated alloys. For alloys such as NiCr, NiV, NiMo, and NiRu, the magnetizations of which deviate from the Slater-Pauling curve, our determination does not correspond to previous works and is consequently discussed. The limits of the model appear mainly due to local-environment effects; in the case of NiMn, it is found that a ternary-alloy model with some Mn atoms in the antiferromagnetic state can account for both stiffness-constant and magnetization behaviors

Earth’s gravity and the cosmological constant: a worked example

International Nuclear Information System (INIS)

Pereira, J A M

2016-01-01

The cosmological constant regained the attention of the scientific community following the recent discovery of the accelerated expansion of the Universe. Consequently, interest in the subject increased amongst the public such that it now often appears in the classroom and popular science publications. The purpose of this article is to use basic concepts of Newtonian mechanics, like dynamics, kinetic energy and potential energy diagrams, in a scenario where the cosmological constant’s action, considered as being an inertial force driven by the accelerated expansion of the Universe, could counteract Earth’s gravity. The effect that the cosmological constant might have near the Earth’s surface is discussed showing how everyday life would change. This is done in such a way that makes it accessible to students in their first year of college. Finally, the modern interpretation of the cosmological constant, associated with the existence of dark energy, is briefly discussed along with upper limit estimations for its value based on the anthropic principle.

We report on the computation of the B s meson decay constant in Heavy Quark Effective Theory on the lattice. The next to leading order corrections in the HQET expansion are included non-perturbatively. We estimate higher order contributions to be very small. The results are extrapolated to the continuum limit, the main systematic error affecting the computation is therefore the quenched approximation used here. The Generalized Eigenvalue Problem and the use of all-to-all propagators are important technical ingredients of our approach that allow to keep statistical and systematic errors under control. We also report on the decay constant f B s ' of the first radially excited state in the B s sector, computed in the static limit. (orig.)

Intra-Household Allocation of Parental Leave

OpenAIRE

Gobbi, Paula Eugenia; Parys, Juliane; Schwerhoff, Gregor

2015-01-01

We introduce childcare sharing in a collective model of household behavior to investigate which factors make spouses increase or decrease their share of parental leave. The concern about future consumption motivates parents to invest in their human capital and to limit their leave duration. Using relative income and the age difference between spouses as distribution factors, we cannot reject Pareto efficiency in childcare sharing. Higher relative incomes and larger age differences shift the c...

This article reports on the development of a brief 15-item parent-report risk index (Child Risk Index for Divorced or Separated Families; CRI-DS) to predict problem outcomes of children who have experienced parental divorce. A series of analyses using 3 data sets were conducted that identified and cross-validated a parsimonious set of items representing parent report of child behavior problems and family level risk and protective factors, each of which contributed to the predictive accuracy of the index. The index predicted child behavior outcomes and substance abuse problems up to 6 years later. The index has acceptable levels of sensitivity and specificity as a screening measure to predict problem outcomes up to 1 year later. The use of the index to identify the need for preventive services is discussed, along with limitations of the study.

Instrument Psychometrics: Parental Satisfaction and Quality Indicators of Perinatal Palliative Care.

Science.gov (United States)

Wool, Charlotte

2015-10-01

Despite a life-limiting fetal diagnosis, prenatal attachment often occurs in varying degrees resulting in role identification by an individual as a parent. Parents recognize quality care and report their satisfaction when interfacing with health care providers. The aim was to test an instrument measuring parental satisfaction and quality indicators with parents electing to continue a pregnancy after learning of a life-limiting fetal diagnosis. A cross sectional survey design gathered data using a computer-mediated platform. Subjects were parents (n=405) who opted to continue a pregnancy affected by a life-limiting diagnosis. Factor analysis using principal component analysis with Varimax rotation was used to validate the instrument, evaluate components, and summarize the explained variance achieved among quality indicator items. The Prenatal Scale was reduced to 37 items with a three-component solution explaining 66.19% of the variance and internal consistency reliability of 0.98. The Intrapartum Scale included 37 items with a four-component solution explaining 66.93% of the variance and a Cronbach α of 0.977. The Postnatal Scale was reduced to 44 items with a six-component solution explaining 67.48% of the variance. Internal consistency reliability was 0.975. The Parental Satisfaction and Quality Indicators of Perinatal Palliative Care Instrument is a valid and reliable measure for parent-reported quality care and satisfaction. Use of this instrument will enable clinicians and researchers to measure quality indicators and parental satisfaction. The instrument is useful for assessing, analyzing, and reporting data on quality for care delivered during the prenatal, intrapartum, and postnatal periods.

Separation of parent homopolymers from diblock copolymers by liquid chromatography under limiting conditions of desorption 4. Role of eluent and temperature.

Berek, Dušan

2010-11-01

Liquid chromatography under limiting conditions of desorption (LC LCD) enables fast, base-line discrimination of both parent homopolymers from various diblock copolymers in one single step. The low molecular admixtures are fully separated, as well. General rules are discussed in detail for selection of mobile phases and temperature applied in LC LCD of block copolymers. Typical practical separation examples are presented. It is shown that both the composition of the well-selected LC LCD mobile phase and the temperature of experiment may vary in a broad range without affecting the basics of method. This implies that the method is robust and user friendly.

The postpartum period represents a major transition in the lives of many women, a time when women are at increased risk for the emergence of psychopathology including depression and PTSD. The current study aimed to better understand the unique contributions of clinically significant postpartum depression, PTSD, and comorbid PTSD/depression on mother-infant bonding and observed maternal parenting behaviors (i.e., behavioral sensitivity, negative affect, positive affect) at 6 months postpartum. Mothers (n=164; oversampled for history of childhood maltreatment given parent study's focus on perinatal mental health in women with trauma histories) and infants participated in 6-month home visit during which dyads engaged in interactional tasks varying in level of difficulties. Mothers also reported on their childhood abuse histories, current depression/PTSD symptoms, and bonding with the infant using standardized and validated instruments. Mothers with clinically significant depression had the most parenting impairment (self-report and observed). Mothers with clinically significant PTSD alone (due to interpersonal trauma that occurred predominately in childhood) showed similar interactive behaviors to those who were healthy controls or trauma-exposed but resilient (i.e., no postpartum psychopathology). Childhood maltreatment in the absence of postpartum psychopathology did not infer parenting risk. Findings are limited by (1) small cell sizes per clinical group, limiting power, (2) sample size and sample demographics prohibited examination of third variables that might also impact parenting (e.g., income, education), (3) self-report of symptoms rather than use of psychiatric interviews. Findings show that in the context of child abuse history and/or current PTSD, clinically significant maternal depression was the most salient factor during infancy that was associated with parenting impairment at this level of analysis.

Full Text Available Background and Aim: Stress is the source of many problems in human-kind lives and threatens people's life constantly. Having hearing-impaired child, not only causes stress in parents, but also affects their marital satisfaction. The purpose of this study was comparing the stress and marital satisfaction status between the normal and hearing-impaired children's parents.Methods: This was a causal-comparative study. Eighty parents of normal children and 80 parents of hearing-impaired children were chosen from rehabilitation centers and kindergartens in city of Tabriz, Iran by available and clustering sampling method. All parents were asked to complete the Friedrich's source of stress and Enrich marital satisfaction questionnaires.Results: Parents of hearing-impaired children endure more stress than the normal hearing ones (p<0.001. The marital satisfaction of hearing-impaired children's parents was lower than the parents of normal hearing children, too (p<0.001.Conclusion: Having a hearing-impaired child causes stress and threatens the levels of marital satisfaction. This requires much more attention and a distinct planning for parents of handicap children to reduce their stress.

[Parenting styles and their relationship with hyperactivity].

2008-11-01

The present study aims to determine the relationship among factors that make up the parenting styles according to the PCRI (Parent-Child Relationship Inventory) and hyperactivity reported by parents through the BASC (Behaviour Assessment System for Children). We selected a sample of 32 children between 3 and 14 years old (23 male and 9 female) with risk scores in hyperactivity and another similar group with low scores in hyperactivity. After administering both instruments to the parents, we carried out a binomial logistic regression analysis which resulted in a prediction model for 84.4% of the sample, made up of the PCRI factors: fathers' involvement, communication and role orientation, mothers' parental support, and both parents' limit-setting and autonomy. Moreover, our analysis of the variance produced significant differences in the support perceived by the fathers and mothers of both groups. Lastly, the utility of results to propose intervention strategies within the family based on an authoritative style is discussed.

This study compared parent-child communication (PCC) patterns and parental role satisfaction (PRS) between women with breast cancer and healthy women. A limited number of studies have examined PCC and the impact of PRS between cancer patients and their children. It was a descriptive survey design comprising the Parent-Adolescent Communication Scale and a PRS measure. Data from 202 participants in total were analysed with two-way analyses of variance and t-tests. Closed communication was higher in both groups than open communication, but higher still in children of women with breast cancer than in children of healthy women. PRS was lower in women with breast cancer than in healthy women. Educational programs should be developed to support parents and children during the post-treatment adjustment period for mothers with breast cancer. Such programs should take a practical approach toward increasing open parent-child communication while considering personal characteristics and cultural backgrounds. Copyright © 2014 Elsevier Inc.

Dockery, Alfred; Li, Jianghong; Kendall, Garth

2009-02-01

Previous research demonstrates that non-standard work schedules undermine the stability of marriage and reduce family cohesiveness. Limited research has investigated the effects of parents working non-standard schedules on children's health and wellbeing and no published Australian studies have addressed this important issue. This paper contributes to bridging this knowledge gap by focusing on adolescents aged 15-20 years and by including sole parent families which have been omitted in previous research, using panel data from the Household, Income and Labour Dynamics in Australia Survey. Multilevel linear regression models are estimated to analyse the association between parental work schedules and hours of work and measures of adolescents' mental health derived from the SF-36 Health Survey. Evidence of negative impacts of parents working non-standard hours upon adolescent wellbeing is found to exist primarily within sole parent families.

Parent-child communication is associated with positive outcomes for youths' engagement in sexual behaviors. Limited data are available regarding parent-child communication in transitional countries. We present data from Vietnamese parent-youth dyads on parent reproductive health (RH) knowledge, comfort of communication, frequency of talk, and discordancy between youths' reported and parents' perceptions for engagement in relationships and sexually intimate behaviors. The cohort included 185 randomly selected parent-youth dyads in four communes in Hanoi and Khanh Hoa Province. Descriptive and comparative analysis included chi-squared tests, independent samples t-tests, and ANOVA. Linear regression analysis was used to assess relationships between parental knowledge, level of comfort, frequency of talk, and discordancy. Seventy-six percent of parents and 44% of youth were female. The mean age of youth was 17.2 years. The mean score for parental "RH knowledge" was 24.74 (SD, 3.84; range, 15-34). Lower parental RH knowledge was positively associated with lower levels of education (F = 2.983; df, 184; p = .014). Data indicate a linear model in which knowledge is related to "comfort" (β = .17; p = .048), and "comfort" to frequency of "talk" (β = .6; p sexual touching (β = .57; p = .60). Parent and youth in Vietnam are engaged in limited communication about RH. There is a need for more data to assess the effect of these communication patterns on youths' engagement in sexual behaviors and for development of family-centered interventions to increase parental knowledge and skills for positive communication.

It is shown that if a quantum field theory has to be consistent with gravity and holography, i.e. with an upper limit of storing information in a given area, the ultraviolet momentum cut-off is not the Planck mass, M_p, as naively expected, but M_p/N_U^(1/4) where N_U is the number of ...

Parent-child interaction: Does parental language matter?

Menashe, Atara; Atzaba-Poria, Naama

2016-11-01

Although parental language and behaviour have been widely investigated, few studies have examined their unique and interactive contribution to the parent-child relationship. The current study explores how parental behaviour (sensitivity and non-intrusiveness) and the use of parental language (exploring and control languages) correlate with parent-child dyadic mutuality. Specifically, we investigated the following questions: (1) 'Is parental language associated with parent-child dyadic mutuality above and beyond parental behaviour?' (2) 'Does parental language moderate the links between parental behaviour and the parent-child dyadic mutuality?' (3) 'Do these differences vary between mothers and fathers?' The sample included 65 children (M age  = 1.97 years, SD = 0.86) and their parents. We observed parental behaviour, parent-child dyadic mutuality, and the type of parental language used during videotaped in-home observations. The results indicated that parental language and behaviours are distinct components of the parent-child interaction. Parents who used higher levels of exploring language showed higher levels of parent-child dyadic mutuality, even when accounting for parental behaviour. Use of controlling language, however, was not found to be related to the parent-child dyadic mutuality. Different moderation models were found for mothers and fathers. These results highlight the need to distinguish parental language and behaviour when assessing their contribution to the parent-child relationship. © 2016 The British Psychological Society.

Whilst the Triple P Positive Parenting Program has a large evidence base (Sanders, Clinical Child and Family Psychology Review 2:71-90, 1999; Sanders, Journal of Consulting and Clinical Psychology 68:624-640, 2000) and preliminary evidence indicates that Stepping Stones Triple P is also efficacious (Roberts, Journal of Clinical Child and Adolescent Psychology, 35(2):180-193, 2006), to date Stepping Stones has not been evaluated with the ASD population. Fifty-nine families with a child with ASD aged between 2 and 9 participated in this randomized controlled trial. The results demonstrate significant improvements in parental reports of child behaviour and parenting styles with the treatment effects for child behaviour, parental over reactivity and parental verbosity being maintained at follow-up 6 months later. Further, the results suggest significant improvements in parental satisfaction and conflict about parenting as well as a sleeper effect for parental efficacy. The results indicate that Stepping Stones Triple P is a promising intervention for parents of children with ASD. Limitations and future research are also addressed.

Maternal and paternal depression has been associated with infants' behavioral sleep problems. Behavioral sleep interventions, which alter parental cognitions about infant sleep, have improved infant sleep problems. This study reports relationships between parental depression, fatigue, sleep quality, and cognitions about infant sleep pre and post-intervention for a behavioral sleep problem. This secondary analysis of data from Canadian parents (n = 455), with healthy infants aged 6-to-8-months exposed to a behavioral sleep intervention, examined baseline data and follow-up data from 18 or 24 weeks post intervention (group teaching or printed material) exposure. Parents reported on sleep quality, fatigue, depression, and cognitions about infant sleep. Data were analyzed using Pearson's r and stepwise regression analysis. Parents' fatigue, sleep quality, sleep cognitions, and depression scores were correlated at baseline and follow-up. At baseline, sleep quality (b = .52, 95% CI .19-.85), fatigue (b = .48, 95% CI .33-.63), doubt about managing infant sleep (b = .44, 95% CI .19-.69), and anger about infant sleep (b = .69, 95% CI .44-.94) were associated with mothers' depression. At baseline, fathers' depression related to sleep quality (b = .42, 95% CI .01-.83), fatigue (b = .47, 95% CI .32-.63), and doubt about managing infant sleep (b = .50, 95% CI .24-.76). At follow-up, mothers' depression was associated with sleep quality (b = .76, 95% CI .41-1.12), fatigue (b = .25, 95% CI .14-.37), doubt about managing infant sleep (b = .44, 95% CI .16-.73), sleep anger (b = .31, 95% CI .02-.59), and setting sleep limits (b = -.22, 95% CI -.41-[-.03]). At follow-up, fathers' depression related to sleep quality (b = .84, 95% CI .46-1.22), fatigue (b = .31, 95% CI .17-.45), sleep doubt (b = .34, 95% CI .05-.62), and setting sleep limits (b = .25, 95% CI .01-.49).

1991-03-01

Community based nurses have increasingly been involved in caring for the parents of drug abusing adolescents. They are in need of research data about how parents are coping with the problem. This study analyzed parental role formulation in response to their position as parents of deviant children. The method of inquiry was ethnographic. Data were gathered from nonparticipant observations, parent informant journals, and interviews with parents involved in a survival group. Parents move through three phases of role formation, the content of which has implications for nursing assessments. The similarities of these parents to those of physically and mentally handicapped children is striking. Both are outside the conventional norm and are constantly involved in interpreting situations with others as to their different parenting role. A pecularity in the findings is that the parents were less discredited by their family and friends than had been anticipated. They met their greatest discreditation from community institutions, including the school, police, and court systems, institutions that were expected to assist them in bringing their child's drug abuse under control.

There has been limited examination of the use of relationship based structured parenting programs that focus on emotional interactions in the parent-child dyad in families where a parent has a mental illness. There is also a lack of awareness of the practicalities of providing such interventions within adult mental health services. This study explores the process and outcomes of a nurse led emotional awareness based parenting program for adult clients of a mental health service. Participants demonstrated a significant reduction in difficult parenting moments and associated stress and distress as well as promising improvements in overall distress and emotional awareness.

The home environment, which includes parenting practices, is an important setting in which children develop their health behaviors. We examined the role of parenting practices in the home environment among underserved youth. We examined baseline data of a family-focused pediatric obesity intervention. Parenting practices (monitoring, discipline, limit setting of soda/snacks [SS] and screen media [SM], pressure to eat, and reinforcement) and availability of fruits/vegetables (FV) and sugar-sweetened beverages (SSBs), family meals, television (TV) watching during meals, TVs in the home, owning active video games/sports equipment, and household food security were assessed in 301 parent/caregivers of overweight/obese children (ages 7-12 years; BMI≥85th percentile). Associations were evaluated using Spearman's rank correlation coefficients and logistic regression models adjusted for potential confounders. Parents/caregivers (ages 22-67 years) were largely Hispanic/Latino (74.1%), female (92.4%), and reported high levels of limit setting SS and low levels of pressure to eat. Parent age, gender, country of birth, and years living in the United States accounted for differences among several parenting practices. Adjusted logistic regression models identified several statistically significant associations, including: Monitoring was positively associated with availability FV (odds ratio [OR]=2.19; 95% confidence interval [CI], 1.25, 3.82); limit setting SS was inversely associated with availability of SSBs (OR=0.40; 95% CI, 0.21, 0.75); and limit setting SM was inversely associated with TV viewing during family meals (OR=0.51; 95% CI, 0.31, 0.85). Nearly 40% of our population was food insecure, and food insecurity was positively associated with pressure to eat (OR=1.77; 95% CI, 1.01, 3.15). Parenting practices play an important role in the home environment, and longitudinal studies are needed to examine these associations in the context of family-focused pediatric obesity

A large number of U.S. children are identified as having special health care needs (CSHCN). Despite parents' central role in managing their child's needs, many parents report difficulties in navigating service systems, finding information about their child's condition, and accessing health care and community resources. Therefore, there is a need for interventions that "activate" parents of children with special health care needs to increase their knowledge, skills, and confidence in managing, coordinating, and advocating for their child's needs. This study sought to review the existing literature and examine the effects of parent support interventions that focus on parental activation either in part or whole, on child, parent, or family outcomes. Specific aims included (a) summarizing the nature and content of interventions; (b) describing changes in relevant outcomes; (c) identifying limitations and making recommendations for future research. Following electronic databases were searched: MEDLINE, EMBASE, PsycINFO via ProQuest, PubMed, Cumulative Index to Nursing and Allied Health via EBSCO, Education Resources Information Center (ERIC) via ProQuest, The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Cochrane Methodology Register), and Google Scholar. Twenty-two studies were selected, data were extracted, and quality was assessed using standardized procedures. Five intervention categories were identified: parent-to-parent supports, psycho-educational groups, content-specific groups, community health worker model, and self-management-based interventions. Although most studies showed positive effects of the intervention, evidence was inconsistent for parental outcomes such as self-efficacy, confidence, strain, depression, and perceived social support. Evidence was more consistent in showing improvement in parent coping and in use of community-based services and resources. There is a need to boost active

Limited research has addressed processes underlying parents' empathic responses to their child's pain. The present study investigated the effects of parental catastrophizing, threatening information about the child's pain, and child pain expression upon parental emotional and behavioral responses to their child's pain. A total of 56 school children participated in a heat pain task consisting of 48 trials while being observed by 1 of their parents. Trials were preceded by a blue or yellow circle, signaling possible pain stimulation (i.e., pain signal) or no pain stimulation (i.e., safety signal). Parents received either neutral or threatening information regarding the heat stimulus. Parents' negative emotional responses when anticipating their child's pain were assessed using psychophysiological measures- i.e., fear-potentiated startle and corrugator EMG activity. Parental behavioral response to their child's pain (i.e., pain attending talk) was assessed during a 3-minute parent-child interaction that followed the pain task. The Child Facial Coding System (CFCS) was used to assess children's facial pain expression during the pain task. Results indicated that receiving threatening information was associated with a stronger parental corrugator EMG activity during pain signals in comparison with safety signals. The same pattern was found for parental fear-potentiated startle reflex, particularly when the child's facial pain expression was high. In addition, parents who reported high levels of catastrophizing thought about their child's pain engaged, in comparison with low-catastrophizing parents, in more pain-attending talk when they received threatening information. The findings are discussed in the context of affective-motivational theories of pain. Copyright © 2011 International Association for the Study of Pain. Published by Elsevier B.V.

Single Mother Parenting and Adolescent Psychopathology.

Daryanani, Issar; Hamilton, Jessica L; Abramson, Lyn Y; Alloy, Lauren B

2016-10-01

Children raised in single-mother families are at increased risk for psychopathology, but the mechanisms that help explain this relationship are understudied. In a community sample of diverse adolescents (N = 385, 52 % female, 48 % Caucasian) and their mothers, we hypothesized that single mothers would be more likely than cohabitating mothers to engage in negative parenting behaviors, which would predict adolescent psychopathology prospectively. Single mothers were more likely to engage in psychologically controlling behaviors, which predicted to their adolescent offspring experiencing higher rates of depressive symptoms and externalizing disorders. Girls were more susceptible to depressive symptoms via psychologically controlling parenting than boys in single-mother families. Further, single mothers were more likely to engage in rejecting parenting behaviors, which predicted to a higher prevalence of adolescent externalizing disorders. Surprisingly, rejection in single-mother families predicted to less severe anxiety symptoms in adolescents relative to two-parent families. It is likely that single mothers are not inherently inferior parents relative to cohabitating mothers; rather, their parenting practices are often compromised by a myriad of demands and stressors. Consistent with this postulate, low socioeconomic status was associated with single motherhood and negative parenting behaviors. Clinical implications and study limitations are discussed.

We present preliminary results of the non-perturbative computation of the RI-MOM renormalization constants in a mass-independent scheme for the action with Iwasaki glue and four dynamical Wilson quarks employed by ETMC. Our project requires dedicated gauge ensembles with four degenerate sea quark flavours at three lattice spacings and at several values of the standard and twisted quark mass parameters. The RI-MOM renormalization constants are obtained from appropriate O(a) improved estimators extrapolated to the chiral limit. (orig.)

Parental control mechanisms and their reflection on identity styles of Turkish adolescents

Directory of Open Access Journals (Sweden)

Hacer Nermin Çelen

2009-04-01

Full Text Available Research has shown that authoritarian parents limit their children's freedom of expression and monitor their children's behavior according to their rules. Children of authoritative families tend to have high self-esteem and refer to internalized norms. Parenting is a cultural product. In this study the model presented is limited in the sense that it does not consider the cultural diversity. We must evaluate the identity not only with perceived parenting style but also within the socio-cultural context. The present study explored the relationships between identity styles and perceived parenting control patterns in late adolescents. Responses of 402 Turkish university students to the Berzonsky's Identity Style Inventory were factor-analyzed, and patterns of correlations between four identity statuses, Steinberg's Authoritative Parenting Scale, and Kağitçibaş1's Authoritarianism Scale and parental education were examined. The findings are discussed in relation to ways of incorporating the cultural context into the study of identity development.

The current study examined the congruence of parent and adolescent reports of positive and negative parenting with observations of parent-adolescent interactions as the criterion measure. The role of parent and adolescent depressive symptoms in moderating the associations between adolescent or parent report and observations of parenting also was examined. Participants were 180 parents (88.9 % female) with a history of clinical depression and one of their 9-to-15 year old children (49.4 % female). Parents and adolescents reported on parenting skills and depressive symptoms, and parenting was independently observed subsequently in the same session. Findings indicated adolescent report of positive, but not negative, parenting was more congruent with observations than parent report. For negative parenting, depressive symptoms qualified the relation between the parent or adolescent report and independent observations. For parents, higher levels of depressive symptoms were associated with more congruence with observed parenting (supporting a depressive realism hypothesis) whereas an opposite trend emerged for adolescents (providing some supporting evidence for a depression-distortion hypothesis).

Type Ia Supernovae Progenitor Problem and the Variation of Fundamental Constants

Directory of Open Access Journals (Sweden)

2016-01-01

Full Text Available Cosmological observations strongly suggest our universe is the interior of an expanding black hole. If the constant mass of the universe is assumed then from the equation for Schwarzschild radius: r S = 2 Gmc it follows that proportionality constant Gc depends linearly on the universe’s radius R u , identified with r S , i.e. Gc Because the Chandrasekhar limit M Ch relates to the speed of light and to the Newton’s constant as M Ch ( c = G 3 = 2 so expansion involves gradual decrease of M Ch . In result, a single white dwarf can alone become the Type Ia supernova progenitor, which provides a complementary solution to single-degenerate and double-degenerate models for SNe Ia. Both alternative scenarios: G R u and c R are analyzed in regard of their consistence with observations, and their consequences to cosmology.

Kamihara, Junne; Nyborn, Justin A; Olcese, Maura E; Nickerson, Taylor; Mack, Jennifer W

2015-05-01

Previous work suggests that parents of children with cancer can remain hopeful despite receiving prognostic information, but we know little about what hope means to such parents, or the extent to which parents can feel hopeful even while facing the child's impending death. We audiotaped conversations between clinicians and parents of 32 children with relapsed or refractory cancer, and then interviewed parents about their hopes and expectations for their child. Parent statements about prognosis in interviews mirrored those made by clinicians during discussions about the child's diagnosis with refractory or relapsed cancer. Clinicians used language referring to hope during these conversations but did not ask parents directly about their hopes. Parents expressed a range of hopes for their children, from hopes related to cure or treatment response, to quality of life, normalcy, and love and relationships for the child. For most parents, expectations about prognosis were not aligned with their hopes for the child; for example, many parents hoped for a cure and also reported that they did not believe cure was possible. Many parents were able to acknowledge this incongruence. Parents accurately conveyed the reality of their child's serious condition in the setting of advanced cancer, and yet maintained hope. Hopes were not limited to hope for cure/treatment response. Clinicians should be encouraged to engage in direct conversations about hope with parents as a means to elicit realistic hopes that can help to focus the most meaningful plans for the child and family.

Teenage parents and their offspring.

Science.gov (United States)

Kaufman, J

1996-06-18

Teenage parents are cast into adult roles before the role experimentation and identity development tasks of middle adolescence can be completed. Understanding the etiology of this social problem requires an ecological perspective encompassing individual characteristics, person-context variables, and societal factors such as race and social class. Risk factors identified in the literature on adolescent pregnancy in the US include: absence of a future orientation or aspirations, lack of assertiveness and interpersonal skills to control physical intimacy, low socioeconomic status and minority group membership, growing up in a single-parent family, a history of sexual abuse, five or more siblings, a sister or friend who became a teenage mother, lax parental supervision of dating and free time, low self-esteem, and dropping out or failing in school. The limited data on adolescent fathers suggest they have histories of substance use, delinquency, failure to graduate from high school, financial difficulty, and exposure to family violence. The offspring of adolescent parents show a higher incidence of developmental delays and mild mental retardation than children of adults and are at increased risk of child abuse and neglect. Teen parents raised in dysfunctional families tend to perpetuate destructive methods of child rearing and have unrealistic, age-inappropriate expectations for infants and toddlers. Teenage parents' lack of competence can be mitigated, however, by positive living arrangements, a supportive family of origin, peer support groups, quality child care, school-based services, and accurate information about parenting and child development.

Attachment, parenting styles and bullying during pubertal years.

Science.gov (United States)

van der Watt, Ronél

2014-01-01

Research that focuses on combining attachment, parenting styles, bullying and the reciprocal nature thereof in the parent-adolescent and peer relationships is limited. The bio-psychosocial changes that adolescents experience open up broader social realities and are perceived differently by parents and adolescents. Attachment processes and parenting styles may elicit dissimilar perceptions. These processes are also associated with the multifaceted dynamics of bullying. The aim of the article is to advocate for research on the possible link between the implications of attachment, parenting styles and bullying. Exploring the association between attachment, parenting styles and bullying can deepen the understanding of the developmental challenges within the parent-adolescent relationship, add insight to the different perceptions of adolescents and parents, and complement intervention programmes accordingly. Firstly, this article outlines bio-psychosocial changes in the pubertal years as related to the social realities of the adolescent. Secondly, a discussion on the concepts 'attachment', 'parenting styles', 'bullying', and the potential link between these concepts will follow. Thirdly, an outline of the clinical implications of the apparent association between these concepts is given. The article concludes with recommendations that researchers can consider while exploring the relationship between attachment, parenting styles, and bullying and the delineation thereof in the parent-adolescent relationship.

Maternal personality and psychopathology as determinants of parenting behavior: a quantitative integration of two parenting literatures.

Science.gov (United States)

McCabe, Jennifer E

2014-05-01

A substantial literature has examined the association between parenting behavior and maternal psychological characteristics (i.e., personality and psychopathology). Although research has provided evidence indicating that personality and psychopathology are not independent of one another, parenting research has mainly focused on these characteristics separately. In the present study, I quantitatively integrated these literatures through meta-analytic path analysis. First, meta-analyses were conducted on articles, book chapters, and dissertations that examined associations between personality or psychopathology and warmth or control in mothers of children age 12 months or older. Using mixed-effects regression, meta-analyses revealed significant, small effect sizes suggesting that low levels of neuroticism and psychopathology and high levels of agreeableness, extraversion, and conscientiousness were associated with adaptive parenting. Moderator analyses indicated that variability among individual studies was partially explained by report method, study design, and conceptualizations of parenting behavior. Meta-analytic path analyses showed that the observed associations between maternal personality/psychopathology and parenting behaviors as reported in the literature may be explained by variance shared among these psychological characteristics. Furthermore, some maternal psychological characteristics explained a significantly larger portion of variance in parenting behavior than others. Findings supported the proposal that maternal personality and psychopathology are not independent in the associations they demonstrate with parenting behaviors and that these areas of research can be integrated. The present study is limited by including only mothers, excluding infants, and using cross-sectional analyses. However, results have implications for future conceptualizations of maternal psychological characteristics as determinants of parenting behaviors and for the refinement

Parental feeding practices shape children's dietary preferences and behaviors, which can influence a child's weight status. Limited research exists on the precursors and contextual influences of feeding, particularly among Hispanic parents. Therefore, this study explored two areas potentially important for obesity prevention in young children: (1) precursors and contextual influences on parental feeding and (2) parental perceptions and knowledge of the child care food environment. Four focus groups (n=36) were held with Hispanic parents, predominantly mothers, of preschool children at two child care centers. Parents were asked about influences on what and how they feed their children, awareness of the child care center feeding environment, and current involvement in the child care center. Themes were coded using NVivo10 software (QSR International, Melbourne, Australia). Participants' childhood experiences influenced how they feed their children. Parents stated that both husbands and grandparents often indulged their children with unhealthy foods and thought this interfered with their efforts to maintain a healthy home environment. Participants reported that what their children ate while in child care sometimes influenced the home feeding environment. Cultural and environmental factors influence parental feeding and involvement in the child care setting. Consistent with socioecological system theory, exploring interactions between the environment and culture using a family focus framework, such as the Family Ecological Model, could provide a better understanding of these influences among Hispanic parents. Future obesity prevention interventions with Hispanic families should be culturally relevant and target the different environments where children spend their time.

Transformational change in parenting practices after child interpersonal trauma: A grounded theory examination of parental response.

Science.gov (United States)

Cummings, Jorden A

2018-02-01

Child interpersonal trauma is associated with a host of negative outcomes, both concurrently and in adulthood. Parental responses following trauma can play an important role in modulating child responses, symptoms, and post-trauma functioning. However, parents themselves are also impacted after their child experiences trauma, reporting distress, psychopathology, concerns about the child's safety, changes in discipline and protectiveness, and feelings of blame. Most of this previous research, however, suffers from methodological limitations such as focusing on description and correlations, providing static "one shot" assessments of parenting after trauma, and relying mainly on results related to child sexual abuse. This project developed a comprehensive, explanatory theory of the dynamic process by which parenting changes in response to a range of child trauma, using a sample of parents whose children had experienced a range of interpersonal trauma types. Grounded theory analyses revealed a three-phase dynamic model of discontinuous transformation, in which parents experienced destabilization, recalibration, and re-stabilization of parenting practices in response to child trauma. Parents were focused on Protecting and Healing the child victim, often at the expense of their own needs. Most parents reached a phase of posttraumatic growth, labelled Thriving Recovery, but processes that hindered this recovery are also discussed. This study provides the first evidence that dynamic systems of change as well as vicarious posttraumatic growth can apply to parents of child trauma victims. Generating an explanatory theory provides important avenues for future research as well as interventions and services aimed at families who have experienced child trauma. Copyright © 2017 The Author.

Molecular dynamics simulations of solutions at constant chemical potential

Perego, C.; Salvalaglio, M.; Parrinello, M.

2015-04-01

Molecular dynamics studies of chemical processes in solution are of great value in a wide spectrum of applications, which range from nano-technology to pharmaceutical chemistry. However, these calculations are affected by severe finite-size effects, such as the solution being depleted as the chemical process proceeds, which influence the outcome of the simulations. To overcome these limitations, one must allow the system to exchange molecules with a macroscopic reservoir, thus sampling a grand-canonical ensemble. Despite the fact that different remedies have been proposed, this still represents a key challenge in molecular simulations. In the present work, we propose the Constant Chemical Potential Molecular Dynamics (CμMD) method, which introduces an external force that controls the environment of the chemical process of interest. This external force, drawing molecules from a finite reservoir, maintains the chemical potential constant in the region where the process takes place. We have applied the CμMD method to the paradigmatic case of urea crystallization in aqueous solution. As a result, we have been able to study crystal growth dynamics under constant supersaturation conditions and to extract growth rates and free-energy barriers.

For homogeneous materials, the ultrasonic immersion method, associated with a numerical optimization process mostly based on Newton's algorithm, allows the determination of elastic constants for various synthetic and natural composite materials. Nevertheless, a principal limitation of the existing optimization procedure occurs when the considered material is at the limit of the homogeneous hypothesis. Such is the case of the woven bidirectional SiC matrix and SiC fibre composite material. In this study, we have developed two numerical methods for the determination of the elastic constants of the 2D SiC/SiC composite material (2D SiC/SiC). The first one is based on Newton's algorithm: the elastic constants are obtained by minimizing the square deviation between experimental and calculated velocities. The second method is based on the Levenberg-Marquardt algorithm. We show that these algorithms give the same results in the case of homogeneous anisotropic composite materials. For the 2D SiC/SiC composite material, the two methods, using the same measured velocities, give different sets of elastic constants. We then note that the Levenberg-Marquardt algorithm enables a better convergence towards a global set of elastic constants in good agreement with the elastic properties, which can be measured using classical quasi-static methods

Parenting programs based on cognitive-behavioral and social learning principles are effective in changing child behavior problems and parenting styles. However, such programs typically have limited population reach. The current study aimed to evaluate the efficacy of a brief radio series that provided parenting advice based on the Triple P-Positive Parenting Program. One hundred thirty-nine parents of children aged 2 to 10 years who had concerns about their child's behavioral and/or emotional adjustment were recruited, randomly assigned to either an intervention or waitlist control group, and completed online self-report measures. Parents in the intervention group were given access to seven Triple P podcasts online over a period of 2 weeks. Parents in the intervention group improved significantly more than parents in the control group, from pre- to postintervention, on measures of child behavioral problems and parenting style, self-efficacy, and confidence. These short-term intervention effects were maintained at the 6-month follow-up. These results suggest that brief radio and online parenting programs can be effective and have the potential to reach a large proportion of parents experiencing child behavior problems. Limitations, clinical significance, and future research suggestions are discussed.

Full Text Available The death of a child is difficult to the bereaved parents. Literature had associated the loss with marriage disruption. The issues on that the difficulties to communicate, gender-related coping mechanisms and sexual need were discussed as reasons for bereaved parents to have conflict in their relationship. However there is limited knowledge about this issue. A pilot study has been conducted among six bereaved parents. The bereaved parents were Malaysian Muslim bereaved parents. They were interviewed individually to explore the challenges or conflicts that they had experienced after the death of their child. This study revealed that there were situations which bereaved parents described as having difficulties in their relationship. However, this study also revealed that the mutual understanding and respect to each other are the most of important components for bereaved parents to maintain their relationship post-loss. This study suggested the importance of suggesting couple counselling to bereaved parents after the death of their child.

Full Text Available Parents influence on their young children's physical activity (PA behaviours was examined in a sample of 102 preschool-aged children (54 boys. Questionnaires regarding family sociodemographics and physical activity habits were completed. Results showed that children who received greater parental support for activity (B=.78, P<.10 and had parents who rated PA as highly enjoyable (B=.69, P<.05 were significantly more likely to engage in one hour or more of daily PA. Being an older child (B=−.08, P<.01, having older parents (B=−.26, P<.01, and watching more than one hour of television/videos per day (B=1.55, P<.01 reduced the likelihood that a child would be rated as highly active. Children who received greater parental support for PA were 6.3 times more likely to be highly active than inactive (B=1.44, P<.05. Thus, parents can promote PA among their preschoolers, not only by limiting TV time but also by being highly supportive of their children's active pursuits.

Association of parental health literacy with oral health of Navajo Nation preschoolers.

Health literacy is 'the capacity to obtain, process and understand basic health information and services needed to make appropriate health decisions'. Although numerous studies show a link between health literacy and clinical outcomes, little research has examined the association of health literacy with oral health. No large-scale studies have assessed these relationships among American Indians, a population at risk for limited health literacy and oral health problems. This analysis was conducted as part of a clinical trial aimed at reducing dental decay among preschoolers in the Navajo Nation Head Start program. Using baseline data for 1016 parent-child dyads, we examined the association of parental health literacy with parents' oral health knowledge, attitudes, and behavior, as well as indicators of parental and pediatric oral health. More limited health literacy was associated with lower levels of oral health knowledge, more negative oral health attitudes, and lower levels of adherence to recommended oral health behavior. Parents with more limited health literacy also had significantly worse oral health status (OHS) and reported their children to have significantly worse oral health-related quality of life. These results highlight the importance of oral health promotion interventions that are sensitive to the needs of participants with limited health literacy. © The Author 2015.

We discuss the leptonic decay constants of heavy-light mesons by means of Borel QCD sum rules in the local-duality (LD) limit of infinitely large Borel mass parameter. In this limit, for an appropriate choice of the invariant structures in the QCD correlation functions, all vacuum-condensate contributions vanish and all nonperturbative effects are contained in only one quantity, the effective threshold. We study properties of the LD effective thresholds in the limits of large heavy-quark mass m{sub Q} and small light-quark mass m{sub q}. In the heavy-quark limit, we clarify the role played by the radiative corrections in the effective threshold for reproducing the pQCD expansion of the decay constants of pseudoscalar and vector mesons. We show that the dependence of the meson decay constants on m{sub q} arises predominantly (at the level of 70-80%) from the calculable m{sub q}-dependence of the perturbative spectral densities. Making use of the lattice QCD results for the decay constants of nonstrange and strange pseudoscalar and vector heavy mesons, we obtain solid predictions for the decay constants of heavy-light mesons as functions of m{sub q} in the range from a few to 100 MeV and evaluate the corresponding strong isospin-breaking effects: f{sub D{sup +}} - f{sub D{sup 0}} = (0.96 ± 0.09) MeV, f{sub D}{sup {sub *}{sub +}} - f{sub D}{sup {sub *}{sub 0}} = (1.18 ± 0.35) MeV, f{sub B{sup 0}} - f{sub B{sup +}} = (1.01 ± 0.10) MeV, f{sub B}{sup {sub *}{sub 0}} - f{sub B}{sup {sub *}{sub +}} = (0.89 ± 0.30) MeV.

BACKGROUND Health Literacy is the ability to obtain, process, and understand health information to make knowledgeable health decisions. PURPOSE To determine baseline health literacy of NICU parents at a tertiary care hospital during periods of crucial information exchange. METHODS Health Literacy of English speaking NICU parents was assessed using the Newest vital Sign (NVS) on admission (n=121) and discharge (n=59). A quasi-control group of well newborn (WBN) parents (n=24) and prenatal obstetric clinic (PRE) parents (n=18) were included. A single, Likert-style question measured nurse’s assessment of parental comprehension with discharge teaching. Suspected limited health literacy (SLHL) was defined as NVS score of ≤3. FINDINGS / RESULTS Forty-three percent of parents on NICU admission and 32% at NICU discharge had SLHL (pNICU parents and 25% of WBN parents with SLHL at time of admission/infant birth had a college education. Nurse subjective measurement of parental comprehension of discharge instructions was not correlated to the objective measurement of health literacy (p=0.26). IMPLICATIONS FOR PRACTICE SLHL is common during peak time periods of complex health discussion in the NICU, WBN, and PRE settings. NICU providers may not accurately gauge parent’s literacy status. IMPLICATIONS FOR RESEARCH Methods for improving health communication are needed. Studies should evaluate SLHL in a larger NICU population and across different languages and cultures. PMID:27391562

Theory of space-charge polarization for determining ionic constants of electrolytic solutions

Science.gov (United States)

Sawada, Atsushi

2007-06-01

A theoretical expression of the complex dielectric constant attributed to space-charge polarization has been derived under an electric field calculated using Poisson's equation considering the effects of bound charges on ions. The frequency dependence of the complex dielectric constant of chlorobenzene solutions doped with tetrabutylammonium tetraphenylborate (TBATPB) has been analyzed using the theoretical expression, and the impact of the bound charges on the complex dielectric constant has been clarified quantitatively in comparison with a theory that does not consider the effect of the bound charges. The Stokes radius of TBA +(=TPB-) determined by the present theory shows a good agreement with that determined by conductometry in the past; hence, the present theory should be applicable to the direct determination of the mobility of ion species in an electrolytic solution without the need to measure ionic limiting equivalent conductance and transport number.

Strong Nuclear Gravitational Constant and the Origin of Nuclear Planck Scale

Directory of Open Access Journals (Sweden)

Seshavatharam U. V. S.

2010-07-01

Full Text Available Whether it may be real or an equivalent, existence of strong nuclear gravitational con- stant G S is assumed. Its value is obtained from Fermi’s weak coupling constant as G S = 6 : 9427284 10 31 m 3 / kg sec 2 and thus “nuclear planck scale” is defined. For strong interaction existence of a new integral charged “confined fermion” of mass 105.383 MeV is assumed. Strong coupling constant is the ratio of nuclear planck energy = 11.97 MeV and assumed 105.383 MeV. 1 s = X s is defined as the strong interaction mass gen- erator. With 105.383 MeV fermion various nuclear unit radii are fitted. Fermi’s weak coupling constant, strong interaction upper limit and Bohr radius are fitted at funda- mental level. Considering Fermi’s weak coupling constant and nuclear planck length a new number X e = 294.8183 is defined for fitting the electron, muon and tau rest masses. Using X s , X e and 105 : 32 = 0 : 769 MeV as the Coulombic energy constant = E c , en- ergy coe cients of the semi-empirical mass formula are estimated as E v = 16 : 32 MeV ; E s = 19 : 37 MeV ; E a = 23 : 86 MeV and E p = 11 : 97 MeV where Coulombic energy term contains [ Z ] 2 : Starting from Z = 2 nuclear binding energy is fitted with two terms along with only one energy constant = 0.769 MeV. Finally nucleon mass and its excited levels are fitted.

Parenting Interventions for Children with Tic Disorders: Professionals' Perspectives.

Evans, Gemma A L; Wittkowski, Anja; Butler, Hannah; Hedderly, Tammy; Bunton, Penny

Tic disorders can have an emotional and social impact on children and families, which can in turn have a reciprocal impact on tics. Research into parenting interventions within this population is limited. Twenty-five professionals' views on the acceptability, effectiveness, feasibility and utility of parenting interventions were explored using Q-methodology. Three highly correlated factors emerged, indicating three viewpoints with discrete elements that were underpinned by similar general perspectives. All factors endorsed a psychological approach, the importance of parenting practices, and theoretical and clinical justifications for parenting interventions. Discrete elements of the viewpoints debated the advocated focus, barriers and audience of interventions. Multidisciplinary professionals endorsed parenting interventions as a therapeutic tool within tic disorders. Results provide suggestions to further develop and implement interventions.

To explore whether changes in parenting self-efficacy after attending a parenting programme are related to changes in parenting stress and child behaviour. Adverse parenting is a risk factor in the development of a range of health and behavioural problems in childhood and is predictive of poor adult outcomes. Strategies for supporting parents are recognised as an effective way to improve the health, well-being and development of children. Parenting is influenced by many factors including the behaviour and characteristics of the child, the health and psychological well-being of the parent and the contextual influences of stress and support. Parenting difficulties are a major source of stress for parents, and parenting self-efficacy has been shown to be an important buffer against parenting stress. In all, 63 parents who had a child under the age of 10 years took part in the research. Of those, 58 returned completed measures of parenting self-efficacy, parenting stress and child behaviour at the start of a parenting programme and 37 at three-month follow-up. Improvements in parenting self-efficacy and parenting stress were found at follow-up, but there was less evidence for improvements in child behaviour. The findings clearly suggest a relationship between parenting self-efficacy and parenting stress; parents who are feeling less efficacious experience higher levels of stress, whereas greater parenting self-efficacy is related to less stress. This study adds to the evidence that parent outcomes may be a more reliable measure of programme effectiveness than child outcomes at least in the short term.

To determine parents' attitudes and awareness of food marketing to children. Computer-assisted telephone interviews of a random sample of 400 parents of children aged 5-17 years and who were the main grocery buyers for that household, living in NSW, Australia. The main outcome measures included parental awareness and attitudes relating to food marketing to children, the perceived role of government versus industry in food marketing regulation and children's food purchasing requests as a result of exposure to food marketing. The majority of parents were concerned about food marketing to children, with the highest level of concern registered for the positioning of food at supermarket checkouts (83% of parents concerned). Parental awareness of certain non-broadcast media food marketing (e.g. print, radio and premium offers) to children was low. The majority of parents (91%) did not trust the industry to protect children from food marketing. Most parents (81%) believed that the government should restrict the use of non-broadcast media marketing of unhealthy food to children. Parents of younger children were more likely to report that their child asked for advertised food products, compared with parents of adolescents (65% and 48% respectively, P channels used to market food to children is important as part of building family and policy efforts to limit exposure to this otherwise relatively unregulated media environment.

The Experience of Prisoners' Parents: A Meta-Synthesis of Qualitative Studies.

Gueta, Keren

2017-08-19

The parents of prisoners have long drawn the attention of researchers, due to their role in the etiology of criminality as well as the importance of their support of their offspring during and after incarceration. However, although studies have shown that the parents of prisoners experience high levels of distress, burden, and social stigma, research into their experience is only now beginning to emerge. This metasynthesis examined the limited body of qualitative research on the experience of prisoners' parents, as an exploratory step toward advancing the understanding of their experience. Relevant terms were used to systematically search key databases. Ten small-scale studies, which varied in focus, location, and disciplinary orientation, met the inclusion criteria. The synthesis produced four core themes, reflecting findings regarding parents' (primarily mothers') experience of their offspring's incarceration: parenting from a distance; the burden of care; troubled parental identity; and social reaction. Furthermore, the findings suggested a number of possible mediating factors of this experience, such as parents' social capital and their cognitive appraisal of their offspring's criminality. These themes imply a possible experience of "imprisonment by association" among the parents of inmates and illuminate features that may be unique to them. Given the inherent limitations regarding generalizability of a metasynthesis and the heterogeneity of the experiences of the parents represented by the articles reviewed, the findings call for future large-scale quantitative studies to explore the challenges and therapeutic needs of parents of prisoners regarding the themes identified. © 2017 Family Process Institute.

Karl Schwarzschild Lecture: The Ups and Downs of the Hubble Constant (With 12 Figures)

Tammann, G. Andreas

2006-01-01

A brief history of the determination of the Hubble constant H_0 is given. Early attempts following Lemaitre (1927) gave much too high values due to errors of the magnitude scale, Malmquist bias and calibration problems. By 1962 most authors agreed that 75< H_0 <130. After 1975 a dichotomy arose with values near 100 and others around 55. The former came from apparent-magnitude-limited samples and were affected by Malmquist bias. New distance indicators were introduced; they were sometimes claimed to yield high values of H_0, but the most recent data lead to H_0 in the 60's, yet with remaining difficulties as to the zero-point of the respective distance indicators. SNe Ia with their large range and very small luminosity dispersion (avoiding Malmquist bias) offer a unique opportunity to determine the large-scale value of H_0. Their maximum luminosity can be well calibrated from 10 SNe Ia in local parent galaxies whose Cepheids have been observed with HST. An unforeseen difficulty - affecting all Cepheid distances - is that their P-L relation varies from galaxy to galaxy, presumably in function of metallicity. A proposed solution is summarized here. The conclusion is that H_0 = 63.2 +/- 1.3 (random) +/- 5.3 (systematic) on all scales. The expansion age becomes then (with Omega_m=0.3, Omega_Lambda=0.7) 15.1 Gyr.

1976-01-01

Absolute rate constants have been determined by the pulse radiolysis technique for several electrophilic reactions of the benzyl, the benzhydryl, and the trityl cation in 1,2-dichloroethane solution. The rate constants for the reactions of these carbonium ions with chloride ion, with bromide ion, and with iodide ion are all very nearly the same, namely 6 x 10 10 M -1 s -1 at 24 0 C. The values very likely represent the diffusion controlled limit for the ion combination reactions. The rate constants for the reactions with triethylamine, tri-n-propylamine, and tri-n-butylamine range from 2.0 x 10 9 to 7 x 10 6 M -1 s -1 at 24 0 C. With increasing phenyl substitution, the decreasing trend in the magnitude of the rate constant is consistent with the combined electronic and steric effects. With increasing size of the amine, the decrease in the value of the rate constant seems to indicate that the steric effect predominates. The values of the rate constants for reactions of benzyl and benzhydryl cation with methanol, ethanol, and 2-propanol indicate the following. The rate constant is higher for reaction with the alcohol dimer in solution than with alcohol monomer. The rate constants for reaction with alcohol monomer have values of 1 x 10 8 M -1 s -1 or lower

Purpose Parent-child communication is associated with positive outcomes for youths’ engagement in sexual behaviors. Limited data are available regarding parent-child communication in transitional countries. We present data from Vietnamese parent-youth dyads on parent reproductive health knowledge, comfort of communication, frequency of talk, and discordancy between youths’ reported and parents’ perceptions for engagement in relationships and sexually intimate behaviors. Methods 185 randomly selected parent-youth dyads in four communes in Ha Noi and Khanh Hoa Province. Descriptive and comparative analysis included chi-square tests, independent samples t-tests, and ANOVA. Linear regression analysis was utilized to assess relationships between parental knowledge, level of comfort, frequency of talk, and discordancy. Results Seventy-six percent of parents and 44% of youth were female. Youth mean age was 17.2 years. For parental “reproductive health knowledge” mean score was 24.74 (SD 3.84: range 15–34). Lower parental reproductive health knowledge was positively associated with lower levels of education [F=2.983, df 184: p=0.014]. Data indicate a linear model in which knowledge is related to “comfort” (β =0.17; p=0.048) and “comfort” to frequency of “talk” (β =0.6; psexual touching (β =0.57; p=0.60). Conclusions Parent and youth in Viet Nam are engaged in limited communication about reproductive health. There is need for more data to assess the impact of these communication patterns on youths’ engagement in sexual behaviors and for development of family-centered interventions to increase parental knowledge and skills for positive communication.

The accuracy of diffusion reactor codes strongly depends on the quality of the groups constants processing. For many years, the generation of such constants was based on 1-D infinity cell transport calculations. Some developments using collision probability or the method of characteristics allow, nowadays, 2-D assembly group constants calculations. However, these 1-D and 2-D codes how some limitations as , for example, on complex geometries and in the neighborhood of heavy absorbers. On the other hand, since Monte Carlos (MC) codes provide accurate neutro flux distributions, the possibility of using these solutions to provide group constants to full-core reactor diffusion simulators has been recently investigated, especially for the cases in which the geometry and reactor types are beyond the capability of the conventional deterministic lattice codes. The two greatest difficulties on the use of MC codes to group constant generation are the computational costs and the methodological incompatibility between analog MC particle transport simulation and deterministic transport methods based in several approximations. The SERPENT code is a 3-D continuous energy MC transport code with built-in burnup capability that was specially optimized to generate these group constants. In this work, we present the preliminary results of using the SERPENT MC code to generate 3-D two-group diffusion constants for a PWR like assembly. These constants were used in the CITATION diffusion code to investigate the effects of the MC group constants determination on the neutron multiplication factor diffusion estimate. (author)

Evidence in promoting positive parenting through the Program-Guide to Develop Emotional Competences

Full Text Available This study aims at providing evidence of the effectiveness of the Program-Guide to Develop Emotional Competences in promoting positive parenting. Contextual, institutional, methodological and professional issues were taken into account to develop a social innovation experience to support parenting as a preventive measure to family conflicts. The study describes both the contents of the Program-Guide and the methodological and evaluation issues that trained professionals need to consider when delivering the Program-Guide to families in natural contexts. Information was gathered and analyzed from 259 parents with children of ages 1-18 who participated in 26 parent training groups. A pre- and post-test design showed that after finishing the sessions parents perceived themselves more competent as parents according to the five dimensions of parenting competences considered: (1 emotional self-regulation abilities; (2 self-esteem and assertiveness; (3 communication strategies; (4 strategies to solve conflicts and to negotiate; and (5 strategies to establish coherent norms, limits and consequences to promote positive discipline. The study presents a discussion on these results from evidence-based parenting programs, as well as some strengths and limitations of the study, together with some suggestions for further research.

Childhood cancer survivors' school (re)entry: Australian parents' perceptions.

McLoone, J K; Wakefield, C E; Cohn, R J

2013-07-01

Starting or returning to school after intense medical treatment can be academically and socially challenging for childhood cancer survivors. This study aimed to evaluate the school (re)entry experience of children who had recently completed cancer treatment. Forty-two semi-structured telephone interviews were conducted to explore parents' perceptions of their child's (re)entry to school after completing treatment (23 mothers, 19 fathers, parent mean age 39.5 years; child mean age 7.76 years). Interviews were analysed using the framework of Miles and Huberman and emergent themes were organised using QSR NVivo8. Parents closely monitored their child's school (re)entry and fostered close relationships with their child's teacher to ensure swift communication of concerns should they arise. The most commonly reported difficulty related to aspects of peer socialisation; survivors either displayed a limited understanding of social rules such as turn taking, or related more to older children or teachers relative to their peers. Additionally, parents placed a strong emphasis on their child's overall personal development, above academic achievement alone. Improved parent, clinician and teacher awareness of the importance of continued peer socialisation during the treatment period is recommended in order to limit the ongoing ramifications this may have on school (re)entry post-treatment completion. © 2013 John Wiley & Sons Ltd.

Cosmological constants and variations

2005-01-01

We review properties of theories for the variation of the gravitation and fine structure 'constants'. We highlight some general features of the cosmological models that exist in these theories with reference to recent quasar data that is consistent with time-variation in the fine structure 'constant' since a redshift of 3.5. The behaviour of a simple class of varying alpha cosmologies is outlined in the light of all the observational constraints. We also discuss some of the consequences of varying 'constants' for oscillating universes and show by means of exact solutions that they appear to evolve monotonically in time even though the scale factor of the universe oscillates

Parental Attitudes, Behaviors, and Barriers to School Readiness among Parents of Low-Income Latino Children

Full Text Available We sought to explore parental attitudes, behaviors, and barriers regarding school readiness in a county clinic serving low income, Latino children. Between December 2013–September 2014, we conducted a cross sectional survey of parents during 3–6 years well-child appointments about school readiness (SR across: (1 attitudes/behaviors; (2 barriers; and (3 awareness; and (4 use of local resources. Most parents (n = 210, response rate 95.6% find it very important/important for their child to know specific skills prior to school: take turns and share (98.5%, use a pencil and count (97.6%, know letters (99.1%, colors (97.1%, and shapes (96.1%. Over 80% of parents find education important and engage in positive SR behaviors: singing, practicing letters, or reading. Major barriers to SR were lack of knowledge for kindergarten readiness, language barriers, access to books at home, constraints on nightly reading, difficulty completing school forms, and limited free time with child. Awareness of local resources such as preschool programs was higher than actual utilization. These low-income, Latino parents value SR but lack knowledge to prepare their child for school and underutilize community resources such as free preschool programs. Pediatricians are uniquely positioned to address these needs, but more evidence-based interventions are needed.

Gadeyne, Els; Ghesquière, Pol; Onghena, Patrick

2004-06-01

We studied the predictive relations between reports of parenting behavior on the one hand and academic achievement and reported behavior problems of young children on the other hand. Data were gathered for 352 children and their parents from kindergarten to 2nd grade. The results indicated that in the academic domain, low supportive and high controlling parenting practices were modestly related to poor subsequent math achievement. Children's externalizing and attention problem behavior was clearly predictive of high levels of control in mothers and low levels of support in fathers. The combination of high parental support and control was especially associated with high levels of problem behavior. However, when previous parenting and child adjustment were taken into account, the magnitude of the predictive power of parenting for child adjustment, and of child adjustment for parenting, remained limited.

Estimation of the effective distribution coefficient from the solubility constant

Wang, Yug-Yea; Yu, C.

1994-01-01

An updated version of RESRAD has been developed by Argonne National Laboratory for the US Department of Energy to derive site-specific soil guidelines for residual radioactive material. In this updated version, many new features have been added to the, RESRAD code. One of the options is that a user can input a solubility constant to limit the leaching of contaminants. The leaching model used in the code requires the input of an empirical distribution coefficient, K d , which represents the ratio of the solute concentration in soil to that in solution under equilibrium conditions. This paper describes the methodology developed to estimate an effective distribution coefficient, Kd, from the user-input solubility constant and the use of the effective K d for predicting the leaching of contaminants

Källén’s constant $M$

Stora, Raymond

2014-01-01

In his Handbook Article [1] G. Källén states the asymptotic condition in quantum electrodynamics where the arrow stands for the “weak” asymptotic limit a la LSZ and M is a finite computable constant expressible in terms of the Källén-Lehmann weight function Π(a) for the photon two point function. All the time, there were conflicting points of view between Källén and LSZ, the former insisting on the canonical formulation (which is sick for coupled fields) and the latter who insist on the asymptotic condition. Amusingly enough followers of LSZ in the framework of LSZ assume [2] which turns out to be inconsistent with perturbative renormalizability. Now Källén’s asymptotic condition is perfectly compatible with LSZ since the free vector field A μ in (x) is associated with a reducible representation of the Poincaré group. The best way to sort this out is to look at massive QED (add a mass term to Källén’s Lagrangian in the Handbook Article, see below). The constant M produces in the cano...

2015-04-01

Children's screen viewing (SV) is associated with higher levels of childhood obesity. Many children exceed the American Academy of Pediatrics guideline of 2 hours of television (TV) per day. There is limited information about how parenting styles and parental self-efficacy to limit child screen time are associated with children's SV. This study examined whether parenting styles were associated with the SV of young children and whether any effects were mediated by parental self-efficacy to limit screen time. Data were from a cross-sectional survey conducted in 2013. Child and parent SV were reported by a parent, who also provided information about their parenting practices and self-efficacy to restrict SV. A four-step regression method examined whether parenting styles were associated with the SV of young children. Mediation by parental self-efficacy to limit screen time was examined using indirect effects. On a weekday, 90% of children watched TV for mediated associations between parental control and SV. Parental control was associated with lower levels of SV among 5- to 6-year-old children. This association was partially mediated by parental self-efficacy to limit screen time. The development of strategies to increase parental self-efficacy to limit screen-time may be useful.

2016-12-01

Parenting programs and self-help parenting interventions employing written materials are effective in reducing child conduct problems (CP) in the short-term compared to control groups, however evidence on the cost-effectiveness of such interventions is insufficient. Few studies have looked at the differences in effects between interventions in the same study design. This study aimed to determine the cost-effectiveness of four parenting programs: Comet, Incredible Years (IY), Cope and Connect, and bibliotherapy, compared to a waitlist control (WC), with a time horizon of 4 months, targeting CP in children aged 3-12 years. This economic evaluation was conducted alongside an RCT of the four parenting interventions and bibliotherapy compared to a WC. The study sample consisted of 961 parents of 3-12 year-old children with CP. CP was measured by the Eyberg Child Behavior Inventory. Effectiveness was expressed as the proportion of "recovered" cases of CP. The time horizon of the study was four months with a limited health sector perspective, including parents' time costs. We performed an initial comparative cost analysis for interventions whose outcomes differed significantly from the WC, and later a cost-effectiveness analysis of interventions whose outcomes differed significantly from both the WC and each other. Secondary analyses were performed: (i) joint outcome "recovered and improved", (ii) intervention completers, (iii) exclusion of parents' time costs, (iv) exclusion of training costs. All interventions apart from Connect significantly reduced CP compared to the WC. Of the other interventions Comet resulted in a significantly higher proportion of recovered cases compared to bibliotherapy. A comparative cost analysis of the effective interventions rendered an average cost per recovered case for bibliotherapy of USD 483, Cope USD 1972, Comet USD 3741, and IY USD 6668. Furthermore, Comet had an ICER of USD 8375 compared to bibliotherapy. Secondary analyses of

Beyond the Hubble Constant

about the distances to galaxies and thereby about the expansion rate of the Universe. A simple way to determine the distance to a remote galaxy is by measuring its redshift, calculate its velocity from the redshift and divide this by the Hubble constant, H0. For instance, the measured redshift of the parent galaxy of SN 1995K (0.478) yields a velocity of 116,000 km/sec, somewhat more than one-third of the speed of light (300,000 km/sec). From the universal expansion rate, described by the Hubble constant (H0 = 20 km/sec per million lightyears as found by some studies), this velocity would indicate a distance to the supernova and its parent galaxy of about 5,800 million lightyears. The explosion of the supernova would thus have taken place 5,800 million years ago, i.e. about 1,000 million years before the solar system was formed. However, such a simple calculation works only for relatively ``nearby'' objects, perhaps out to some hundred million lightyears. When we look much further into space, we also look far back in time and it is not excluded that the universal expansion rate, i.e. the Hubble constant, may have been different at earlier epochs. This means that unless we know the change of the Hubble constant with time, we cannot determine reliable distances of distant galaxies from their measured redshifts and velocities. At the same time, knowledge about such change or lack of the same will provide unique information about the time elapsed since the Universe began to expand (the ``Big Bang''), that is, the age of the Universe and also its ultimate fate. The Deceleration Parameter q0 Cosmologists are therefore eager to determine not only the current expansion rate (i.e., the Hubble constant, H0) but also its possible change with time (known as the deceleration parameter, q0). Although a highly accurate value of H0 has still not become available, increasing attention is now given to the observational determination of the second parameter, cf. also the Appendix at the

A constraint on the distance dependence of the gravitational constant

International Nuclear Information System (INIS)

Hut, P.

1981-01-01

Extended supergravity theories predict the existence of vector and scalar bosons, besides the gravitation, which in the static limit couple to the mass. An example is the gravitation, leading to antigravity. If these bosons have a small mass (approx. -4 eV), an observable Yukawa term would be present in the gravitational potential in the newtonian limit. This can be parametrized by a distance dependent effective gravitational constant G(γ). Defining G 0 = G (10 cm) and Gsub(e) = G (10 3 km), the comparison between theory and observations of the white dwarf Sirius B results in Gsub(c)/G 0 = 0.98 +- 0.08. (orig.)

Many parents diagnose food allergy in their child without seeking medical care and there is limited research on this group. This study investigated parental QoL and mental health in parents of children with parent-diagnosed food allergy (PA), medically diagnosed food allergy (MA), and a control group with no allergy (NA). Methods. One hundred and fifty parents from a general population completed validated measures of QoL, anxiety, depression, and stress. Results. Parents of children with food allergy (PA or MA) reported higher stress, anxiety, and depression than the control group (all p food allergy related QoL compared to parents of children with PA (p food allergy have significantly poorer mental health compared to healthy controls, irrespective of whether food allergy is medically diagnosed or not. It is important to encourage parents to have their child medically tested for food allergy and to recognise and refer for psychological support where needed.

This study describes attitudes and social and environmental factors that affect African American parents' intent to vaccinate their daughters against human papillomavirus (HPV). Thirty African American parents of daughters aged nine to 17 years and no history of HPV infection completed semi-structured interviews. Interviews addressed factors that influenced intent to vaccinate, perception of community norms related to vaccination, vaccination scenarios involving place of vaccination, and vaccination prior to or after the child's initiation of sexual activity. A recurring theme was the influence of physician recommendation on African American parents' intent to obtain HPV vaccination for their daughters. Most parents reported that they could overcome barriers to vaccination, except vaccine costs and lack of insurance. While religious beliefs were important to parents, they reported that they would not interfere with vaccination decisions; fears of early sexuality due to vaccination were limited. The implications of these findings are discussed.

Music therapy (MT) is a therapeutic practice where a therapist uses music to enhance the life quality for their patients. Children have an innate enjoyment of music, making music an effective medium for exploring their potential. In this study, we explore the parental perception of MT through an online survey. Contrary to the public perception that MT only addresses emotional needs, 47 out of 59 parents reported seeing improvements in other areas including behavioral, cognitive, linguistic, and social changes. All but one parent indicated that they would recommend MT to others. The survey results further revealed that even parents of children participating in MT had misconceptions regarding MT, which we describe in the paper. Parents reported inaccessibility and cost as other major limitations surrounding MT adoption. We conclude by discussing how technology solutions could mitigate issues with definition, distance, and cost, while maintaining the benefits of MT.

Tachyon constant-roll inflation

Mohammadi, A.; Saaidi, Kh.; Golanbari, T.

The constant-roll inflation is studied where the inflaton is taken as a tachyon field. Based on this approach, the second slow-roll parameter is taken as a constant which leads to a differential equation for the Hubble parameter. Finding an exact solution for the Hubble parameter is difficult and leads us to a numerical solution for the Hubble parameter. On the other hand, since in this formalism the slow-roll parameter η is constant and could not be assumed to be necessarily small, the perturbation parameters should be reconsidered again which, in turn, results in new terms appearing in the amplitude of scalar perturbations and the scalar spectral index. Utilizing the numerical solution for the Hubble parameter, we estimate the perturbation parameter at the horizon exit time and compare it with observational data. The results show that, for specific values of the constant parameter η , we could have an almost scale-invariant amplitude of scalar perturbations. Finally, the attractor behavior for the solution of the model is presented, and we determine that the feature could be properly satisfied.

Varying Constants, Gravitation and Cosmology

Directory of Open Access Journals (Sweden)

Jean-Philippe Uzan

2011-03-01

Full Text Available Fundamental constants are a cornerstone of our physical laws. Any constant varying in space and/or time would reflect the existence of an almost massless field that couples to matter. This will induce a violation of the universality of free fall. Thus, it is of utmost importance for our understanding of gravity and of the domain of validity of general relativity to test for their constancy. We detail the relations between the constants, the tests of the local position invariance and of the universality of free fall. We then review the main experimental and observational constraints that have been obtained from atomic clocks, the Oklo phenomenon, solar system observations, meteorite dating, quasar absorption spectra, stellar physics, pulsar timing, the cosmic microwave background and big bang nucleosynthesis. At each step we describe the basics of each system, its dependence with respect to the constants, the known systematic effects and the most recent constraints that have been obtained. We then describe the main theoretical frameworks in which the low-energy constants may actually be varying and we focus on the unification mechanisms and the relations between the variation of different constants. To finish, we discuss the more speculative possibility of understanding their numerical values and the apparent fine-tuning that they confront us with.

Parents of children with a life-limiting disease have to rely on themselves at home while adequate paediatric palliative care is lacking. In several countries, paediatric palliative care teams are introduced to ensure continuity and quality of care and to support the child and the family. Yet, little is known about how parents experience such multidisciplinary teams. To obtain insight into the support provided by a new paediatric palliative care team from the parents' perspective. An interpretative qualitative interview study using thematic analysis was performed. A total of 47 single or repeated interviews were undertaken with 42 parents of 24 children supported by a multidisciplinary paediatric palliative care team located at a university children's hospital. The children suffered from malignant or non-malignant diseases. In advance, parents had limited expectations of the paediatric palliative care team. Some had difficulty accepting the need for palliative care for their child. Once parents experienced what the team achieved for their child and family, they valued the team's involvement. Valuable elements were as follows: (1) process-related aspects such as continuity, coordination of care, and providing one reliable point of contact; (2) practical support; and (3) the team members' sensitive and reliable attitude. As a point of improvement, parents suggested more concrete clarification upfront of the content of the team's support. Parents feel supported by the paediatric palliative care team. The three elements valued by parents probably form the structure that underlies quality of paediatric palliative care. New teams should cover these three valuable elements.

Protonation constants of hydroquinone and stability constants of thorium hydroquinone complexes were determined in 1 M NaClO 4 medium at 25 ± 0.5 degC, by varying concentration of thorium, using pH titration technique. Protonation constants of hydroquinone (β 1H = [HQ]/[H][Q] and β 2H = [H 2 Q]/[H] 2 [Q]) were found to be β 1H = 11.404 ± 0.014 and β 2H = 21.402 ± 0.012. The analysis of titration data of thorium-hydroquinone system appears to indicate the formation of species Th(H 2 Q) 3 (OH) and Th(H 2 O) 4 (OH). Equilibrium constants obtained for these species are -log β 13-I = 48.51 ± 0.67 and -log β 14-1 64.86 ± 1.25 respectively which are not reported in the literature. (author)

2015-06-01

To examine factors which predict parenting stress in a longitudinal cohort of children born very preterm, and seen at age 7 years. We recruited 100 very preterm (≤32 weeks gestational age) child-parent dyads and a control group of 50 term-born dyads born between 2001 and 2004 with follow-up at 7 years. Parents completed the Parenting Stress Index, Ways of Coping Questionnaire, Child Behavior Check List, Beck Depression Inventory and the State Trait Anxiety Inventory questionnaires. Child IQ was assessed using the Wechsler Intelligence Scale-IV. After controlling for maternal education, parents of preterm children (95% CI 111.1 to 121.4) scored higher (p=0.027) on the Parenting Stress Index than term-born controls (95% CI 97.8 to 113.2). Regression analyses showed that child externalising behaviour, sex and parent escape/avoidance coping style, predicted higher parenting stress in the preterm group. Parents of preterm girls expressed higher levels of stress than those of boys. Maladaptive coping strategies contribute to greater stress in parents of very preterm children. Our findings suggest that these parents need support for many years after birth of a very preterm infant. Published by the BMJ Publishing Group Limited.

Clawson, Ashley H; Jurbergs, Niki; Lindwall, Jennifer; Phipps, Sean

2013-11-01

This study examined the relationships between parental posttraumatic stress symptoms (PTSS), child PTSS, and parent-child concordance for child PTSS. Participants were children with cancer (n = 199), and healthy children (n = 108) and their parents. Children self-reported on PTSS and parents completed measures of child and parent PTSS. In the cancer group, child and parent reports of child PTSS were significantly correlated with no mean differences between reporters. In contrast, correlations were non-significant in the control group, and parents reported significantly lower levels of child PTSS than children. Increased parental PTSS was associated with better concordance in the cancer group but not in the control group. In fact, in the cancer group, parent-child concordance was strongest at the highest level of parental PTSS. Parents of children with cancer were found to be accurate reporters of their children's distress, even with high levels of reported personal distress. In contrast, parents of healthy children appear primarily influenced by personal distress when reporting child PTSS. Although multiple informant assessments are always desirable, it appears that utilization of a single informant may be reasonable in the cancer setting when access to informants is limited.

Bedells, Ella; Bevan, Ann

2016-03-01

This article reviews the literature on nurses' and parents' self-perceived roles when caring for hospitalised children, focusing on research conducted since the Department of Health published the National Service Framework for Children: Standard for Hospital Services in 2003. Three main themes emerge from the review: nurses' perceptions, parents' perceptions, and negotiation. Clarification of what nurses and parents consider to be their respective roles when caring for hospitalised children is a prerequisite for negotiation of those roles. The family's background, life experiences and circumstances influence the effectiveness of negotiation between nurses and parents. The article explores potential barriers to negotiation, including poor communication and failure to provide information. Limitations of the research and the implications for practice are considered.

Emergence of the product of constant curvature spaces in loop quantum cosmology

Dadhich, Naresh; Joe, Anton; Singh, Parampreet

2015-01-01

The loop quantum dynamics of Kantowski–Sachs spacetime and the interior of higher genus black hole spacetimes with a cosmological constant has some peculiar features not shared by various other spacetimes in loop quantum cosmology. As in the other cases, though the quantum geometric effects resolve the physical singularity and result in a non-singular bounce, after the bounce a spacetime with small spacetime curvature does not emerge in either the subsequent backward or the forward evolution. Rather, in the asymptotic limit the spacetime manifold is a product of two constant curvature spaces. Interestingly, though the spacetime curvature of these asymptotic spacetimes is very high, their effective metric is a solution to Einstein’s field equations. Analysis of the components of the Ricci tensor shows that after the singularity resolution, the Kantowski–Sachs spacetime leads to an effective metric which can be interpreted as the ‘charged’ Nariai, while the higher genus black hole interior can similarly be interpreted as an anti Bertotti–Robinson spacetime with a cosmological constant. These spacetimes are ‘charged’ in the sense that the energy–momentum tensor that satisfies Einstein’s field equations is formally the same as the one for the uniform electromagnetic field, albeit it has a purely quantum geometric origin. The asymptotic spacetimes also have an emergent cosmological constant which is different in magnitude, and sometimes even its sign, from the cosmological constant in the Kantowski–Sachs and the interior of higher genus black hole metrics. With a fine tuning of the latter cosmological constant, we show that ‘uncharged’ Nariai, and anti Bertotti–Robinson spacetimes with a vanishing emergent cosmological constant can also be obtained.

2012-01-01

To examine beliefs about the role of parenting in feeding and childhood obesity among mothers of lower socioeconomic status. Individual semistructured, audiotaped interview with 91 mothers of preschool-aged children (49% of mothers obese, 21% of children obese) in the midwestern United States. Participant comments were transcribed and common themes were identified using the constant comparative method and NVivo software. Mothers often described their parents' feeding style as authoritarian or neglectful, and their own current style as comparatively indulgent and better. Mothers described parents of overweight children as inept or neglectful, but they never described their own parenting as such. Encouraging mothers to reflect on how they were fed as children, how it may influence their current parenting, and how the relationship between mothering and child obesity is complex are important nutrition education opportunities.

Associations of Parental Rules and Socioeconomic Position With Preschool Children's Sedentary Behaviour and Screen Time.

Science.gov (United States)

Downing, Katherine L; Hinkley, Trina; Hesketh, Kylie D

2015-04-01

There is little current understanding of the influences on sedentary behavior and screen time in preschool children. This study investigated socioeconomic position (SEP) and parental rules as potential correlates of preschool children's sedentary behavior and screen time. Data from the Healthy Active Preschool Years (HAPPY) Study were used. Participating parents reported their child's usual weekly screen time and their rules to regulate their child's screen time. Children wore accelerometers for 8 days to objectively measure sedentary time. Children whose parents limited television viewing spent significantly less time in that behavior and in total screen time; however, overall sedentary behavior was unaffected. An association between parents limiting computer/electronic game use and time spent on the computer was found for girls only. SEP was inversely associated with girls', but not boys', total screen time and television viewing. As parental rules were generally associated with lower levels of screen time, intervention strategies could potentially encourage parents to set limits on, and switch off, screen devices. Intervention strategies should target preschool children across all SEP areas, as there was no difference by SEP in overall sedentary behavior or screen time for boys.

Since parental personality traits are assumed to play a role in parenting behaviors, the current study examined the relation between parental personality and parenting style among 688 Dutch parents of adolescents in the SMILE study. The study assessed Big Five personality traits and derived parenting styles (authoritative, authoritarian, indulgent, and uninvolved) from scores on the underlying dimensions of support and strict control. Regression analyses were used to determine which personality traits were associated with parenting dimensions and styles. As regards dimensions, the two aspects of personality reflecting interpersonal interactions (extraversion and agreeableness) were related to supportiveness. Emotional stability was associated with lower strict control. As regards parenting styles, extraverted, agreeable, and less emotionally stable individuals were most likely to be authoritative parents. Conscientiousness and openness did not relate to general parenting, but might be associated with more content-specific acts of parenting.

On the evaluation of temperature dependence of elastic constants of martensitic phases in shape memory alloys from resonant ultrasound spectroscopy studies

International Nuclear Information System (INIS)

Landa, Michal; Sedlak, Petr; Sittner, Petr; Seiner, Hanus; Heller, Ludek

2008-01-01

Elastic constants of austenite and martensite phases in shape memory alloys reflect fundamental thermodynamic properties of these materials-i.e. important physical information can be deduced not just from the values of the constants but, mainly from their temperature and stress dependencies. As regards to the parent austenite phase, such information is available in the literature for most of the known shape memory alloys. For the martensitic phases, however, only few reliable experimental data exist, due to the experimental difficulties with the preparation of martensite single crystals as well as due to the difficulties with the ultrasonic measurement of elastic properties of strongly anisotropic media with low symmetry. In this work, the temperature dependence of all elastic constants of cubic austenite and orthorhombic 2H martensite phases in Cu-Al-Ni alloy determined by resonance ultrasound spectroscopy (RUS) is reported. Experimental and theoretical improvements of the RUS method which had to be made to perform the successful measurements on strongly anisotropic and martensitic phases are discussed

2018-05-30

Paid parental leave policies have the potential to strengthen economic supports, reduce family discord, and provide opportunities to empower women (Basile et al., 2016; Niolon et al., 2017). In this article, we present a theory of change and evidence to suggest how paid parental leave may impact intimate partner violence (IPV). In doing so, we present three mechanisms of change (i.e., reduction in financial stress, increase in egalitarian parenting practices, and promotion of child/parent bonding) through which paid parental leave could reduce rates of IPV. We also describe limitations of the current state of knowledge in this area, as well as opportunities for future research. Ultimately, our goal is to facilitate the identification and implementation of approaches that have the potential to reduce violence at the population level. Paid parental leave embodies the potential of policies to change societal-level factors and serve as an important prevention strategy for IPV. Copyright © 2018. Published by Elsevier Inc.

parents. Eight databases were searched for studies evaluating mindful parenting programs from 1997 to November 2014. A three-step search strategy was utilized to retrieve both published and unpublished studies written in English from PubMed, PsycINFO, EMBASE, Scopus, Psychological and Behavioral Sciences Collection, CINAHL, Cochrane Library and ProQuest Dissertations and Theses databases. A logic grid was developed for each of the eight databases to identify the indexing terms and synonyms for the keywords "mindful" and "parenting". Methodological limitations included small sample sizes leading to lack of statistical power, multiple testing leading to increased alpha errors in addition to information bias caused by a lack of blinding in the implementation and assessment phase. The data extraction process entailed using the standardized data extraction form from Joanna Briggs Institute Meta-analysis of Statistics Assessment and Review Instrument to extract data from the selected studies. The heterogeneity of the samples, the measurement tools and outcomes measured precluded data synthesis through meta-analysis. Conclusions on intervention effects were based on comparisons of the overall statistical significance of the outcomes data. The search yielded 1232 articles, from which seven randomized controlled trials met the inclusion criteria. The findings indicate mindful parenting programs may reduce parental stress, increase parents' emotional awareness of their 10-14-year-old children and reduce preschool children's symptoms associated with externalizing disorders. A recurring finding was that the mindful parenting programs reduced parents' emotional dismissal of their adolescents and preschoolers. At present, there is insufficient evidence to conclude that mindful parenting programs can improve parents' and children's wellbeing because of the methodological quality of the few studies that met the inclusion criteria. Although there is currently insufficient evidence

Risks to the offspring from parental occupational exposures

Risks to the offspring of workers with occupational chemical exposures may derive from mutagenic, teratogenic or carcinogenic effects of industrial agents to which the parents are exposed. Evidence for impaired pregnancies and hazards to the offspring of working populations with chemical exposures is, however, very limited. Evidence is reviewed for hazards to the offspring resulting from parental occupational exposure to vinyl chloride, benzene, chloroprene, radiation and petroleum-derived hydrocarbons. Other environmental and behavioral factors with major effects on pregnancy outcome are considered. These include smoking, alcohol, and drug exposures. An approach to surveillance for chromosomal abnormalities in offspring of occupationally exposed parents is outlined

to gain an in-depth understanding of the parenting experiences of bereaved parents in the years following an infant death. an exploratory qualitative study. semi-structured interview in the participants' homes. Data were collected over a five-month period in 2008 and analysed using thematic analysis. a purposive sample of 13 bereaved parents (10 mothers and three fathers) was used. Parents who had accessed the support services offered by two bereavement support agencies were recruited. Participants were asked to describe their experiences of raising their subsequent child. Interviews were conducted when the next born child was at least three years of age. the parents described a 'paradoxical' parenting style where they were trying to parent using two diametrically opposed unsustainable options. For example, they described trying to hold their subsequent child emotionally close but aloof at the same time. the results from this study indicate that the impact of a loss of an infant has far-reaching consequences on subsequent parenting. Support and early intervention at the time of the stillbirth and subsequent pregnancy are likely to be useful. However, further research is required to determine the extent to which early intervention can alter the tendency towards bereaved parents adopting a paradoxical parenting style. The impact of this style on mental health and the emotional health and well-being of the next born child/ren after perinatal loss should also be further examined. Copyright © 2010 Elsevier Ltd.

Hanna, K M; Dashiff, C J; Stump, T E; Weaver, M T

2013-09-01

Parent-adolescent shared responsibility for diabetes care is advocated by experts to achieve beneficial diabetes and psychosocial outcomes for adolescents with type 1 diabetes. Parental autonomy support may be a way to facilitate this sharing. In this dyadic study, we examined parental diabetes-specific autonomy support experienced by adolescents with type 1 diabetes and their parents (n = 89 dyads), and its association with their experience of shared diabetes care responsibility. Path analysis was used to test an Actor-Partner Interdependence Model for parental autonomy support effects on shared responsibility. This was a secondary analysis of data from 89 parent-early/mid-adolescent dyads. Actor effects were identified. Parents' and adolescents' perceptions of parental autonomy support were associated with their respective reports of shared diabetes care responsibility. One partner effect was identified. Adolescents' reports of parental autonomy support were associated with parents' reports of shared responsibility. Parents and adolescents held similar views of autonomy support but discrepant views of shared responsibility. Older adolescents perceived less parental autonomy support. Increasing parental autonomy support may facilitate parent-adolescent sharing of diabetes care responsibility. Adolescent and parent perceptions influence each other and need to be considered when working with them to strengthen parental autonomy support. © 2012 John Wiley & Sons Ltd.

Parent-Adolescent Sexual and Reproductive Health Communication Is Very Limited and Associated with Adolescent Poor Behavioral Beliefs and Subjective Norms: Evidence from a Community Based Cross-Sectional Study in Eastern Ethiopia.

Directory of Open Access Journals (Sweden)

Yadeta Dessie

Full Text Available While parent-adolescent sexual and reproductive health (SRH communication is one potential source of SRH information for adolescents, it appears to be inadequately practiced in Ethiopia. This study was designed to investigate the factors that limit or improve parent-adolescent SRH communication in Harar, Eastern Ethiopia.A community based cross-sectional study was done on 4,559 adolescents of age 13-18. SRH communication was measured using a nine-item scale whose response ranged from "not at all" to "always." Summated composite score ranging from 0-36 was generated; higher score indicates high SRH communication. A median value of the composite score was 4 out of the possible 36 with an Interquartile Range (IQR of 7. Respondents were ranked as very poor, poor and satisfactory communicators based on 33rd and 67th percentiles values. Generalized ordered logit model was applied to investigate the factors associated with SRH communication.Results showed that the adolescents who were more likely to practice poor-very poor/very poor SRH communication were those who had poor behavioral beliefs on and poor subjective norms of communicating sexual issues with parents and those who perceived their parents' reproductive health (RH knowledge as poor. Nonetheless, the probability of poor-very poor/very poor SRH communication was less with high adolescent-parent communication quality, television co-viewing and discussions, and self-disclosure.Curtailing the adolescents' underlying poor beliefs and norms, and improving adolescent-parent communication quality, self-disclosure, and television co-viewing and discussions are essential to engage the parents in sexual and reproductive health education of the adolescents.

Ellipses of constant entropy in the XY spin chain

International Nuclear Information System (INIS)

Franchini, F; Its, A R; Jin, B-Q; Korepin, V E

2007-01-01

Entanglement in the ground state of the XY model on the infinite chain can be measured by the von Neumann entropy of a block of neighbouring spins. We study a double scaling limit: the size of the block is much larger than 1 but much smaller than the length of the whole chain. The entropy of the block has an asymptotic limit in the gapped regimes. We study this limiting entropy as a function of the anisotropy and of the magnetic field. We identify its minima at product states and its divergencies at the quantum phase transitions. We find that the curves of constant entropy are ellipses and hyperbolas, and that they all meet at one point (essential critical point). Depending on the approach to the essential critical point, the entropy can take any value between 0 and ∞. In the vicinity of this point, small changes in the parameters cause large change of the entropy

RNA structure and scalar coupling constants

Tinoco, I. Jr.; Cai, Z.; Hines, J.V.; Landry, S.M.; SantaLucia, J. Jr.; Shen, L.X.; Varani, G. [Univ. of California, Berkeley, CA (United States)

Signs and magnitudes of scalar coupling constants-spin-spin splittings-comprise a very large amount of data that can be used to establish the conformations of RNA molecules. Proton-proton and proton-phosphorus splittings have been used the most, but the availability of {sup 13}C-and {sup 15}N-labeled molecules allow many more coupling constants to be used for determining conformation. We will systematically consider the torsion angles that characterize a nucleotide unit and the coupling constants that depend on the values of these torsion angles. Karplus-type equations have been established relating many three-bond coupling constants to torsion angles. However, one- and two-bond coupling constants can also depend on conformation. Serianni and coworkers measured carbon-proton coupling constants in ribonucleosides and have calculated their values as a function of conformation. The signs of two-bond coupling can be very useful because it is easier to measure a sign than an accurate magnitude.

Sibling comparison of differential parental treatment in adolescence: gender, self-esteem, and emotionality as mediators of the parenting-adjustment association.

Feinberg, M E; Neiderhiser, J M; Simmens, S; Reiss, D; Hetherington, E M

2000-01-01

This study employs findings from social comparison research to investigate adolescents' comparisons with siblings with regard to parental treatment. The sibling comparison hypothesis was tested on a sample of 516 two-child families by examining whether gender, self-esteem, and emotionality-which have been found in previous research to moderate social comparison-also moderate sibling comparison as reflected by siblings' own evaluations of differential parental treatment. Results supported a moderating effect for self-esteem and emotionality but not gender. The sibling comparison process was further examined by using a structural equation model in which parenting toward each child was associated with the adjustment of that child and of the child's sibling. Evidence of the "sibling barricade" effect-that is, parenting toward one child being linked with opposite results on the child's sibling as on the target child-was found in a limited number of cases and interpreted as reflecting a sibling comparison process. For older siblings, emotionality and self-esteem moderated the sibling barricade effect but in the opposite direction as predicted. Results are discussed in terms of older siblings' increased sensitivity to parenting as well as the report of differential parenting reflecting the child's level of comfort and benign understanding of differential parenting, which buffers the child against environmental vicissitudes evoking sibling comparison processes.

Early engagement in advance care planning (ACP) is seen as fundamental for ensuring the highest standard of care for children and young people with a life-limiting condition (LLC). However, most families have little knowledge or experience of ACP. To investigate how parents of children and young people with LLCs approach and experience ACP. Open-ended, semi-structured interviews were conducted with parents of 18 children; nine children who were currently receiving palliative care services, and nine children who had received palliative care and died. Verbatim transcripts of audiotaped interviews were analysed following principles of grounded theory while acknowledging the use of deductive strategies, taking account of both the child's condition, and the timing and nature of decisions made. Parents reported having discussions and making decisions about the place of care, place of death and the limitation of treatment. Most decisions were made relatively late in the illness and by parents who wished to keep their options open. Parents reported different levels of involvement in a range of decisions; many wished to be involved in decision making but did not always feel able to do so. This study highlights that parents' approaches to decision making vary by the type of decision required. Their views may change over time, and it is important to allow them to keep their options open. We recommend that clinicians have regular discussions over the course of the illness in an effort to understand parents' approaches to particular decisions rather than to drive to closure prematurely. © 2016 The Authors Health Expectations Published by John Wiley & Sons Ltd.

Parenting styles and conceptions of parental authority during adolescence.

Smetana, J G

1995-04-01

Reports of parenting styles were assessed in 110 primarily white, middle-class sixth, eighth, and tenth graders (M = 11.98, 13.84, and 16.18 years of age) and their parents (108 mothers and 92 fathers). Parents judged the legitimacy of parental authority and rated family conflict and rules regarding 24 hypothetical moral, conventional, personal, multifaceted (containing conventional and personal components), prudential, and friendship issues. Adolescents viewed their parents as more permissive and more authoritarian than parents viewed themselves, whereas parents viewed themselves as more authoritative than did adolescents. Parents' parenting styles differentiated their conceptions of parental authority, but adolescents' perceptions did not. Differences were primarily over the boundaries of adolescents' personal jurisdiction. Furthermore, conceptions of parental authority and parenting styles both contributed significantly to emotional autonomy and adolescent-parent conflict. The implications of the findings for typological models of parenting and distinct domain views of social-cognitive development are discussed.

Parental depression is a major risk factor in child development. Growing research suggests parenting programs can positively impact parental depressive symptoms, although the specific mechanisms that explain these effects are unknown. The current study examined parenting mediated effects of a parenting program on mothers' and fathers' depressive symptoms, as well as the role of child behavior in linking parenting to reductions in depressive symptoms. The study samples included 494 mothers and 288 fathers of Mexican origin adolescents who participated in a randomized trial of the Bridges to High School Program/Proyecto Puentes a la Secundaria, a universal prevention and promotion intervention that included parent training but did not directly target parental depressive symptoms. Parenting mediator models tested program effects on parental depressive symptoms through changes in harsh and supportive parenting. Results showed a significant indirect intervention effect on maternal depressive symptoms through changes in mothers' harsh parenting. Next, child behavior models revealed a partial mediation effect of harsh parenting and a full mediation effect of supportive parenting on maternal depressive symptoms through mothers' reports of child externalizing symptoms. Indirect effects of fathers' harsh and supportive parenting on paternal depressive symptoms were also found through fathers' reports of child behavior.

Parents are an important influence on children's dietary intake and eating behaviors. However, the lack of a conceptual framework and inconsistent assessment of food parenting practices limits our understanding of which food parenting practices are most influential on children. The aim of this study was to develop a food parenting practice conceptual framework using systematic approaches of literature reviews and expert input. A previously completed systematic review of food parenting practice instruments and a qualitative study of parents informed the development of a food parenting practice item bank consisting of 3632 food parenting practice items. The original item bank was further reduced to 110 key food parenting concepts using binning and winnowing techniques. A panel of 32 experts in parenting and nutrition were invited to sort the food parenting practice concepts into categories that reflected their perceptions of a food parenting practice conceptual framework. Multi-dimensional scaling produced a point map of the sorted concepts and hierarchical cluster analysis identified potential solutions. Subjective modifications were used to identify two potential solutions, with additional feedback from the expert panel requested. The experts came from 8 countries and 25 participated in the sorting and 23 provided additional feedback. A parsimonious and a comprehensive concept map were developed based on the clustering of the food parenting practice constructs. The parsimonious concept map contained 7 constructs, while the comprehensive concept map contained 17 constructs and was informed by a previously published content map for food parenting practices. Most of the experts (52%) preferred the comprehensive concept map, while 35% preferred to present both solutions. The comprehensive food parenting practice conceptual map will provide the basis for developing a calibrated Item Response Modeling (IRM) item bank that can be used with computerized adaptive testing

Farr, Rachel H; Grant-Marsney, Holly A; Grotevant, Harold D

2014-12-01

As adoptees transition to adulthood, their roles in the family may shift, providing them with opportunities to have increasing autonomy in their decisions about contact and initiating conversations about adoption. Research has often focused more on adoptees as children, yet in emerging adulthood, there are important shifts in the life roles and relationships of adoptees during which adoptive parents continue to be meaningful. This study examined associations among attachment and communication within the adoptive family during adulthood with emerging adult adoptees' experience of birth family contact (frequency of and satisfaction with birth family contact), in a sample of 167 emerging adults with varied contact with birth family (from no contact to frequent contact). Results suggest that perceptions of secure parent-child attachment relationships, as well as sensitive and open communication with adoptive parents about adoption, continue to be important for emerging adult adoptees and lead to greater satisfaction for adoptees with birth parent contact-regardless of whether adoptees actually have birth family contact. In particular, positive family communication about adoption during adulthood was predictive of satisfaction with birth parent contact. Limitations and implications are discussed. © 2014 Family Process Institute.

2012-01-01

Background This study tested the theoretical assumption that transformations of parent-child relationships in late childhood and adolescence would differ for boys following different offending trajectories. Methods Using longitudinal multiinformant data of 503 boys (ages 7–19), we conducted Growth Mixture Modeling to extract offending trajectories. Developmental changes in child reports of parent-child joint activities and relationship quality were examined using Latent Growth Curves. Results Five offending trajectories were found: non-offenders, moderate childhood offenders, adolescent-limited offenders, serious childhood offenders, and serious persistent offenders. Non-offenders reported high and stable levels of relationship quality between age 10 and 16. Adolescent-limited offenders reported a similarly high relationship quality as non-offenders at ages 7 and 10, but a lower and decreasing relationship quality in adolescence. Compared with non-offenders, serious persistent offenders reported poorer parent-child relationship quality at all ages, and a decreasing relationship quality in adolescence. Serious persistent offenders and adolescent-limited offenders reported similar levels and changes in parent-child relationship quality in adolescence. Although serious persistent offenders reported fewer joint activities at age 10 and 13 than non-offenders, a similar linear decrease in joint activities in early to middle adolescence was found for boys in each trajectory. Conclusion Developmental changes in parent-child relationship quality differ for different types of offenders. This finding has scientific and practical implications. PMID:22816682

The aim of this study was to better understand the utility of using the Parents' Evaluation of Developmental Status (PEDS) in well-child visits by analyzing themes and patterns in parents' written responses on the PEDS form. We reviewed a consecutive sample of medical records with PEDS forms for children aged 6 months to 9 years (site 1) and 3 to 5 years (site 2). We recorded the concerns that parents identified in response to the 10 PEDS questions along with demographic information. We then categorized parents' written comments about those concerns according to comment content. We used qualitative and quantitative methods for analysis. We collected 752 PEDS forms. Ninety percent of the parents endorsed at least 1 concern (94.6% on the English forms versus 69.7% on the Spanish forms; P Parents qualified 27.5% of their concerns with a written comment. In 23.9% of cases in which parents identified a concern and provided a written comment, the content of the comment did not match the question's intent; rates of mismatch were similar for the English and Spanish forms. Among comments regarding behavioral concerns, 12% reflected a misunderstanding of age-appropriate behavior. Medical concerns accounted for 14.1% of the comments; these concerns were more common on English forms (61.3%) than on Spanish forms (1.7%) (P Parents frequently used the PEDS forms to communicate additional concerns regarding their child or provide positive feedback on their child's progress. The inappropriate developmental expectations, limited health literacy, and culturally distinct comments on the PEDS forms reinforce the importance of using screening tools to enhance the care provided during visits but not to replace patient-provider communication.

2017-03-01

The increased prevalence of autism spectrum disorder (ASD) among Latino children, later diagnosis, limited access to bicultural specialist support, and worsened health outcomes when compared to non-Latinos points to the need for a culturally relevant parent education intervention. This pilot study examined the feasibility, acceptability, and preliminary outcomes of a culturally derived intervention, Parents Taking Action, for 19 Spanish-speaking mothers of children with ASD. This study introduces the Promotora de Salud Model of intervention delivery to the autism field. A mixed-methods design including one group pre- and posttest design and focus groups was used to evaluate the outcomes of PTA. We found that the intervention was both feasible to implement and acceptable to participants. We also found significant increases in empowerment oriented outcomes for parents between pre- and posttest suggesting that the intervention is promising. Suggestions for future research and practice are offered. © 2015 Family Process Institute.

Several studies have suggested that the genetic liability for autism may be expressed in non-autistic relatives of autistic probands, in behavioral characteristics that are milder but qualitatively similar to the defining features of autism. We employ a variety of direct assessment approaches to examine both personality and language in parents ascertained through having two autistic children (multiple-incidence autism parents) and parents of Down syndrome probands. Multiple-incidence autism parents had higher rates of particular personality characteristics (rigidity, aloofness, hypersensitivity to criticism, and anxiousness), speech and pragmatic language deficits, and more limited friendships than parents in the comparison group. The implications of these findings for future genetic studies of autism are discussed.

Despite numerous advances in the recognition, assessment, and management of pain in neonates over the past two decades, there has been limited improvement in the knowledge base regarding parental responses to their infant's pain. This study examined parents' views of their experiences observing and coping with their infant's pain in the neonatal intensive care unit (NICU). Twelve participants were recruited using purposive sampling from two groups: (a) parents who had infants currently receiving care in the NICU (n=6); and (b) parents whose infants had been discharged from the NICU and were enrolled in the outpatient follow-up clinic at each hospital (n=6). An exploratory, semi-structured format was used to interview parents individually (n=5) or in focus groups (n=7) regarding their infant's clinical course, infant pain experiences, and the parenting experience during and after the NICU stay. Thematic content analysis was used to develop conceptual categories. Two broad themes were identified: (a) infant pain as a source of parental distress and (b) relief of parental distress due to infant's pain.

Gulsrud, Amanda; Kasari, Connie

2016-01-01

Enhancing immediate and contingent responding by caregivers to children’s signals is an important strategy to support social interactions between caregivers and their children with autism. Yet, there has been limited examination of parents’ responsive behaviour in association with children’s social behaviour post caregiver-mediated intervention. Eighty-five dyads were randomized to one of two 10-week caregiver-training interventions. Parent–child play interactions were coded for parental responsivity and children’s joint engagement. Significant gains in responsivity and time jointly engaged were found post JASPER parent-mediated intervention over a psychoeducation intervention. Further, combining higher levels of responsive behaviour with greater adoption of intervention strategies was associated with greater time jointly engaged. Findings encourage a focus on enhancing responsive behaviour in parent-mediated intervention models. PMID:26797940

On the constant-roll inflation

2018-03-01

The primordial power spectra of scalar and tensor perturbations during slow-roll inflation are usually calculated with the method of Bessel function approximation. For constant-roll or ultra slow-roll inflation, the method of Bessel function approximation may be invalid. We compare the numerical results with the analytical results derived from the Bessel function approximation, and we find that they differ significantly on super-horizon scales if the constant slow-roll parameter ηH is not small. More accurate method is needed for calculating the primordial power spectrum for constant-roll inflation.
