  3. Selected cost considerations for geothermal district heating in existing single-family residential areas

    Energy Technology Data Exchange (ETDEWEB)

    Rafferty, Kevin

    1996-06-01

    In the past, district heating (geothermal or conventionally fueled) has not been widely applied to the single-family residential sector. Low-heat load density is the commonly cited reason for this. Although it's true that load density in these areas is much lower than for downtown business districts, other frequently overlooked factors may compensate for load density. In particular, costs for distribution system installation can be substantially lower in some residential areas due to a variety of factors. This reduced development cost may partially compensate for the reduced revenue resulting from low-load density. This report examines cost associated with the overall design of the system (direct or indirect system design), distribution piping installation, and customer branch lines. It concludes with a comparison of the costs for system development and the revenue from an example residential area.

  5. Existence families, functional calculi and evolution equations

    CERN Document Server

    deLaubenfels, Ralph

    1994-01-01

    This book presents an operator-theoretic approach to ill-posed evolution equations. It presents the basic theory, and the more surprising examples, of generalizations of strongly continuous semigroups known as 'existent families' and 'regularized semigroups'. These families of operators may be used either to produce all initial data for which a solution in the original space exists, or to construct a maximal subspace on which the problem is well-posed. Regularized semigroups are also used to construct functional, or operational, calculi for unbounded operators. The book takes an intuitive and constructive approach by emphasizing the interaction between functional calculus constructions and evolution equations. One thinks of a semigroup generated by A as etA and thinks of a regularized semigroup generated by A as etA g(A), producing solutions of the abstract Cauchy problem for initial data in the image of g(A). Material that is scattered throughout numerous papers is brought together and presented in a fresh, ...

  11. Familial Breast and Bowel Cancer: Does It Exist?

    Directory of Open Access Journals (Sweden)

    2004-02-01

    Full Text Available Abstract There is much debate in the literature about familial predispositions to breast and bowel cancers yet little evidence is forthcoming to suggest that there are susceptibility genes that can account for such kindreds. Within the context of known susceptibility genes the most controversial syndrome is hereditary non-polyposis colorectal cancer (HNPCC. In HNPCC, breast cancers do occur yet their incidence overall is no different to that of the general population yet when studied at the molecular level these tumours often display DNA microsatellite instability suggesting that they do indeed belong to this genetic entity. In this review we examine the relationship between breast and bowel cancer and suggest a possible explanation for the diverse points of view described in the literature.

  15. Parental experience of family resources in single-parent families having a child with cancer.

    Science.gov (United States)

    Huang, I-Chen; Mu, Pei-Fan; Chiou, Tzeon-Jye

    2008-10-01

    The purpose of this study was to explore the essence of family experiences in terms of family resources and how these assist a single-parent caring for a child with cancer. When families face stresses caused by cancer, they need to readjust their roles, interactive patterns and relationships, both inside and outside the family. During the adaptation process, family resources may assist recovery from stress and a return to equilibrium. Most research has emphasised the support resources available to two-parent families during the treatment process. There is a lack of information on the experiences of single-parent families and their available resources together with the functions and roles played by family resources during the adjustment process. Qualitative. Five major themes were identified: (i) facing the disease with courage; (ii) hope kindled by professionals; (iii) constructing parental role ability; (iv) assisting the children to live with the illness; and (v) family flexibility. The results of the current study demonstrate that single-parent families with a child suffering from cancer employ family resources to assist family adjustment and to maintain family function/equilibrium. These results explain the dynamic interactions between the multiple levels of resources available to the family. The study results provide evidence-based information that identifies the nature of family resources in single-parent families and describes how these resources can be applied to assist the families.

  1. Family strengths, motivation, and resources as predictors of health promotion behavior in single-parent and two-parent families.

    Science.gov (United States)

    Ford-Gilboe, M

    1997-06-01

    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.

  6. Cost of Incremental Expansion of an Existing Family Medicine Residency Program.

    Ashkin, Evan A; Newton, Warren P; Toomey, Brian; Lingley, Ronald; Page, Cristen P

    2017-07-01

    Expanding residency training programs to address shortages in the primary care workforce is challenged by the present graduate medical education (GME) environment. The Medicare funding cap on new GME positions and reductions in the Health Resources and Services Administration (HRSA) Teaching Health Center (THC) GME program require innovative solutions to support primary care residency expansion. Sparse literature exists to assist in predicting the actual cost of incremental expansion of a family medicine residency program without federal or state GME support. In 2011 a collaboration to develop a community health center (CHC) academic medical partnership (CHAMP), was formed and created a THC as a training site for expansion of an existing family medicine residency program. The cost of expansion was a critical factor as no Federal GME funding or HRSA THC GME program support was available. Initial start-up costs were supported by a federal grant and local foundations. Careful financial analysis of the expansion has provided actual costs per resident of the incremental expansion of the residencyRESULTS: The CHAMP created a new THC and expanded the residency from eight to ten residents per year. The cost of expansion was approximately $72,000 per resident per year. The cost of incremental expansion of our residency program in the CHAMP model was more than 50% less than that of the recently reported cost of training in the HRSA THC GME program.

  9. On the methodology of dialectology of language families : determining the existence of a dialect areal

    Directory of Open Access Journals (Sweden)

    Simona Klemenčič

    2010-12-01

    Full Text Available The author treats the processes that lead to the establishment of a prehistorical dialect area, in other words, a connection between two or more proto-related languages in a known or unknown geographical territory. The dialectology of linguistic families must, as every inductive inquiry, frequently allow a certain degree of vagueness if it is to come to any conclusions. However, the discrepancy between a good and bad interpretation of linguistic material can be significant. This is demonstrated by the analysis of examples that linguists have adduced in support of a prehistorical ancient Balkan-Baltic-Slavic dialect areal. By examining the argumentation theory, the author reveals typical fallacies and questionable methods in the process of reaching conclusions. These are: 1 the attempt to interpret material from a poorly attested language (the linguistic laws are unknown, etymologies unverifiable; 2 comparison of roots (because of the small number of elements and the typically simple structures, there is high probability that the similarity is coincidental; 3 circular reasoning, in which the author explains a fact with an unproven premise; examples where the author is led to a decision among variant readings by a preferred outcome; 4 drawing equivalencies among various types of proper nouns and appellatives without consideration of the methodological problems surrounding them; 5 ignorance of facts concerning a linguistic phenomenon that exists outside of the areal under consideration, as well as failure to consider the full weight of the evidence; 6 uncritical appropriation of findings from other disciplines and the transfer of these findings to comparative linguistics; 7 the explanation of poorly attested material with further poorly attested material; 8 explanation failing to follow logically from the material. With the aid of some of the procedures adduced we can prove the existence of dialect areals that are known never to have existed in

  10. Familiality of co-existing ADHD and tic disorders: evidence from a large sibling study

    2016-07-01

    Full Text Available AbstractBackground: The association of attention-deficit/hyperactivity disorder (ADHD and tic disorder (TD is frequent and clinically important. Very few and inconclusive attempts have been made to clarify if and how the combination of ADHD+TD runs in families. Aim: To determine the first time in a large-scale ADHD sample whether ADHD+TD increases the risk of ADHD+TD in siblings and, also the first time, if this is independent of their psychopathological vulnerability in general. Methods: The study is based on the International Multicenter ADHD Genetics (IMAGE study. The present sub-sample of 2815 individuals included ADHD-index patients with co-existing TD (ADHD+TD, n=262 and without TD (ADHD-TD, n=947 as well as their 1606 full siblings (n=358 of the ADHD+TD index patients and n=1248 of the ADHD-TD index patients. We assessed psychopathological symptoms in index patients and siblings by using the strength and difficulties questionnaire (SDQ and the parent and teacher Conners’ long version Rating Scales (CRS. For disorder classification the Parental Account of Childhood Symptoms (PACS-Interview was applied in n = 271 children. Odds ratio with the GENMOD procedure (PROCGENMOD was used to test if the risk for ADHD, TD and ADHD+TD in siblings was associated with the related index patients’ diagnoses. In order to get an estimate for specificity we compared the four groups for general psychopathological symptoms.Results: Co-existing ADHD+TD in index patients increased the risk of both comorbid ADHD+TD and TD in the siblings of these index patients. These effects did not extend to general psychopathology. Interpretation: Co-existence of ADHD+TD may segregate in families. The same holds true for TD (without ADHD. Hence, the segregation of TD (included in both groups seems to be the determining factor, independent of further behavioral problems. This close relationship between ADHD and TD supports the clinical approach to carefully assess ADHD in

    Lateral nanostructures in membranes, so-called rafts, are believed to strongly influence membrane properties and functions. The experimental observation of rafts has proven difficult as they are thought to be dynamic structures that likely fluctuate on nano- to microsecond time scales. Using neutron diffraction we present direct experimental evidence for the co-existence of gel and fluid lipid domains in a single-component phospholipid membrane made of DPPC as it undergoes its main phase transition. The coherence length of the neutron beam sets a lower limit for the size of structures that can be observed. Neutron coherence lengths between 30 and 242A used in this study were obtained by varying the incident neutron energy and the resolution of the neutron spectrometer. We observe Bragg peaks corresponding to co-existing nanometer sized structures, both in out-of-plane and in-plane scans, by tuning the neutron coherence length. During the main phase transition, instead of a continuous transition that shows a pseudo-critical behavior, we observe the co-existence of gel and fluid domains.

    2015-01-01

    Evidence suggests that regular family meals protect against unhealthy eating and obesity during childhood and adolescence. However, there is limited information on ways to promote family meals as part of health promotion and obesity prevention efforts. The primary aim of this review was to synthesize the literature on strategies to promote family meals among families with school-aged children and adolescents. First, we reviewed interventions that assess family meals as an outcome and summarized strategies that have been used in these interventions. Second, we reviewed correlates and barriers to family meals to identify focal populations and target constructs for consideration in new interventions. During May 26–27, 2014, PubMed and PsycInfo databases were searched to identify literature on family meals published between January 1, 2000 and May 27, 2014. Two reviewers coded 2,115 titles/abstracts, yielding a sample of 139 articles for full-text review. Six interventions and 43 other studies presenting data on correlates of or barriers to family meals were included in the review. Four interventions resulted in greater family meal frequency. Although there were a small number of interventions, intervention settings were diverse and included the home, community, medical settings, the workplace, and the Internet. Common strategies were goal setting and interactive group activities, and intervention targets included cooking and food preparation, cost, shopping, and adolescent influence. Although methodological nuances may contribute to mixed findings, key correlates of family meals were employment, socioeconomic and demographic factors, family structure, and psychosocial constructs. Barriers to consider in future interventions include time and scheduling challenges, cost, and food preferences. Increasing youth involvement in mealtime, tailoring interventions to family characteristics, and providing support for families experiencing time-related barriers are suggested

    Homeless Mentally Ill (HMI) patients pose a challenge in treatment, management and rehabilitation services. HMI patients are often difficult to engage in treatment, and associated with relapse and rehospitalization, even after recovery. Family plays an important role in treatment engagement and care of the mentally ill person in India. Here, we report two unknown psychiatric patients who were reintegrated to their families using newer technologies with existing service. Newer technologies have helped in early identification of HMI families and reintegration into them. The early reintegration reduced the unnecessary detention of HMI patients inside the hospital after recovery. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available We report a family with a rare genetic disorder arising out of mutation in the gene that encodes for the enzyme lecithin-cholesterol acyltransferase (LCAT. The proband presented with nephrotic syndrome, hemolytic anemia, cloudy cornea, and dyslipidemia. Kidney biopsy showed certain characteristic features to suggest LCAT deficiency, and the enzyme activity in the serum was undetectable. Mother and younger sister showed corneal opacity and dyslipidemia but no renal or hematological involvement. These two members had a milder manifestation of the disease called fish eye disease. This case is presented to emphasize the importance of taking family history and doing a good clinical examination in patients with nephrotic syndrome and carefully analyze the lipid fractions in these subset of patients.

    Full Text Available This work deals with the operation, modeling, simulation, and cost evaluation of two different cold storage systems for a single-family house in Italy, that differ from one another on the cold storage material. The two materials used to perform the numerical simulations of the cold storage systems are represented by cold water and a phase change material (PCM, and the numerical simulations have been realized by means of numerical codes written in Matlab environment. The main finding of the present work is represented by the fact that, for the considered user characteristics, and under the Italian electricity tariff policy, the use of a proper designed cold storage system characterized by an effective operation strategy could represent a viable solution from an economical point of view.

    This paper presents a method for forecasting the load for space heating in a single-family house. The forecasting model is built using data from sixteen houses located in Sønderborg, Denmark, combined with local climate measurements and weather forecasts. Every hour the hourly heat load for each...... house the following two days is forecasted. The forecast models are adaptive linear time-series models and the climate inputs used are: ambient temperature, global radiation and wind speed. A computationally efficient recursive least squares scheme is used. The models are optimized to fit the individual...... noise and that practically all correlation to the climate variables are removed. Furthermore, the results show that the forecasting errors mainly are related to: unpredictable high frequency variations in the heat load signal (predominant only for some houses), shifts in resident behavior patterns...

    Full Text Available Peroxisome proliferators-activated receptor (PPAR gene family members exhibit distinct patterns of distribution in tissues and differ in functions. The purpose of this study is to investigate the evolutionary impacts on diversity functions of PPAR members and the regulatory differences on gene expression patterns. 63 homology sequences of PPAR genes from 31 species were collected and analyzed. The results showed that three isolated types of PPAR gene family may emerge from twice times of gene duplication events. The conserved domains of HOLI (ligand binding domain of hormone receptors domain and ZnF_C4 (C4 zinc finger in nuclear in hormone receptors are essential for keeping basic roles of PPAR gene family, and the variant domains of LCRs may be responsible for their divergence in functions. The positive selection sites in HOLI domain are benefit for PPARs to evolve towards diversity functions. The evolutionary variants in the promoter regions and 3′ UTR regions of PPARs result into differential transcription factors and miRNAs involved in regulating PPAR members, which may eventually affect their expressions and tissues distributions. These results indicate that gene duplication event, selection pressure on HOLI domain, and the variants on promoter and 3′ UTR are essential for PPARs evolution and diversity functions acquired.

    Haagerup, Christian Deichmann

    from 2003 to 2006. The activity in the construction sector has been increasing too, but with some time lag caused by what seems to be an inelastic supply. In the long run, house prices will be determined by the replacement cost of houses, e.g. the cost of constructing a similar house including the cost...... of land. This can be used as a guide as to how much prices are to fall, in order to bring them back to the fundamental value. It can also be seen as a warning or indication of a price bubble. This paper presents a calculation of the value of Tobin's q for single-family houses in Denmark from 1968 to 2008....... It shows that the value of Tobin's q has risen by around 40 percent from 2003 to 2006, caused by increasing house prices. This was not a sustainable development, and prices and the value of Tobin's q are now falling. In order for the value of Tobin's q to reach its fundamental value of 1, prices have...

  1. National impacts of the Weatherization Assistance Program in single-family and small multifamily dwellings

    1993-05-01

    Since 1976, the US Department of Energy (DOE) has operated one of the largest energy conservation programs in the nation -- the low-income Weatherization Assistance Program. The program strives to increase the energy efficiency of dwellings occupied by low-income persons in order to reduce their energy consumption, lower their fuel bills, increase the comfort of their homes, and safeguard their health. It targets vulnerable groups including the elderly, people with disabilities, and families with children. The most recent national evaluation of the impacts of the Program was completed in 1984 based on energy consumption data for households weatherized in 1981. DOE Program regulations and operations have changed substantially since then: new funding sources, management principles, diagnostic procedures, and weatherization technologies have been incorporated. Many of these new features have been studied in isolation or at a local level; however, no recent evaluation has assessed their combined, nationwide impacts to date or their potential for the future. In 1990, DOE initiated such an evaluation. This evaluation is comprised of three ``impact`` studies (the Single-Family Study, High-Density Multifamily Study, and Fuel-Oil Study) and two ``policy`` studies. Altogether, these five studies will provide a comprehensive national assessment of the Weatherization Assistance Program as it existed in the 1989 Program Year (PY 1989). This report presents the results of the first phase of the Single-Family Study. It evaluates the energy savings and cost effectiveness of the Program as it has been applied to the largest portion of its client base -- low-income households that occupy single-family dwellings, mobile homes, and small (2- to 4-unit) multifamily dwellings. It is based upon a representative national sample that covers the full range of conditions under which the program was implemented in PY 1989.

    Full Text Available For the effective and safe management of complex care needs for patients in community settings, high quality family medicine (FM training programmes are needed. In less primary care oriented countries, training standards statements for FM postgraduate training are less commonly found. The aim of this study was to review international training standards statements in FM postgraduate training and to catalogue these statements to be used as a best practice standard guide for FM training programs in Germany.A structured three-tiered search was performed: a systematic literature search in MEDLINE®; a search of international indicator databases; and a search in grey literature, consisting of a survey of international experts and a search in "Google (Scholar". From all identified documents, training standards statements were extracted, translated and summarized into categories referring to the same quality aspect.The search strategy revealed 25 relevant documents (MEDLINE® n = 15, databases n = 2, experts n = 7, "Google" n = 1, containing 337 training standards statements. These were summarized into 80 statements. They covered structure quality (n = 35; process quality (n = 43; and two training standards statements referred to outcome quality (n = 2.A broad range of internationally sourced training standards statements for FM postgraduate training could be identified from countries with well-established primary care systems. Only few statements internationally referred to outcome quality, expressing the difficulty in assessing outcome. The resulting inventory of training standards statements for FM postgraduate training can serve as a resource for institutions seeking to formalise and systematise FM training at regional or national levels.

    To examine whether family-based treatment (FBT) for adolescent bulimia nervosa (BN), which emphasizes family involvement in helping to reduce binge eating and purging behaviors, is differentially efficacious in single-parent families versus two-parent families. Forty-one adolescents (97.6% female; 16.0 +/- 1.7 years old) with either BN (n = 18) or subthreshold BN (n = 23) were randomized to FBT as part of a larger randomized controlled trial studying treatments for adolescent BN. Two-parent (n = 27; 65.9%) and single-parent (n = 14; 34.2%) families were compared on demographic variables, presence of comorbid psychiatric illnesses, and symptoms of BN at baseline, post, and 6-month follow-up. ANOVA and chi-square analyses revealed no statistically significant differences between two-parent and single-parent families on any variables with the exception of ethnicity, for which a greater proportion of Caucasians and Hispanic families had two- parent families compared with African-American families (chi(2) = 8.68, p = .01). These findings suggest that FBT may be an appropriate and efficacious treatment for single-parent families as well as two-parent families, despite the reliance on parental intervention to reduce bulimic symptoms and normalize eating patterns.

    This study was done to compare factors influencing children's self-esteem between two parent families and single parent families. The participants were 692 children aged 11 to 13 yr (388 in two parent families and 304 in single parent families) recruited from 20 community agencies and 5 elementary schools in Gyeonggi Province and Seoul City, South Korea. Data were collected from May to July, 2007 using a survey questionnaire containing items on self-esteem, internal control, problematic behavior, school record, family hardiness, parent-child communication and social support. The data were analyzed using SPSS 15.0 program and factors affecting children's self-esteem were analyzed by stepwise multiple regression. Scores for the study variables were significantly different between the two groups. The factors influencing children's self-esteem were also different according to family type. For two parent families, internal control, problematic behavior, school record, and parent-child communication significantly predicted the level of self-esteem (adjusted R(2)=.505, psingle parent families, social support, family hardiness, internal control, problematic behavior, school record, and parent-child communication significantly predicted the level of self-esteem (adjusted R(2)=.444, p<.001). Nurse working with children should consider family type-specific factors influencing their self-esteem.

    Cross-sectional and longitudinal research has shown that family meals are protective for adolescent healthful eating behaviors. However, little is known about what parents think of these findings and whether parents from single- vs dual-headed households have differing perspectives about the findings. In addition, parents' perspectives regarding barriers to applying the findings on family meals in their own homes and suggestions for more widespread adoption of the findings are unknown. The current study aimed to identify single- and dual-headed household parents' perspectives regarding the research findings on family meals, barriers to applying the findings in their own homes, and suggestions for helping families have more family meals. The current qualitative study included 59 parents who participated in substudy of two linked multilevel studies-EAT 2010 (Eating and Activity in Teens) and Families and Eating and Activity in Teens (F-EAT). Parents (91.5% female) were racially/ethnically and socioeconomically diverse. Data were analyzed using a grounded theory approach. Results from the current study suggest that parents from both single- and dual-headed households have similar perspectives regarding why family meals are protective for healthful eating habits for adolescents (eg, provides structure/routine, opportunities for communication, connection), but provide similar and different reasons for barriers to family meals (eg, single-headed=cost vs dual-headed=lack of creativity) and ideas and suggestions for how to increase the frequency of family meals (eg, single-headed=give fewer options vs dual-headed=include children in the meal preparation). Findings can help inform public health intervention researchers and providers who work with adolescents and their families to understand how to approach discussions regarding reasons for having family meals, barriers to carrying out family meals, and ways to increase family meals depending on family structure.

    This is a cross-sectional study which objectives are 1) to determine the predictors for perceived quality of life and 2) to analyze the differences between women from single-parent families and bi-parent families, about their quality of life, depression and familiar income. We worked with a non-probabilistic sample of 140 women from Monterrey, N.L, Mexico, 107 are from bi-parent families and 33 from single parent families. Some of the results show that women from single-parent families have lower quality of life (Z = -2.224, p = .026), lower income (Z = -2.727, p = .006) and greater depression (Z = -6.143, p = .001) than women from bi-parental families. The perceived quality of life's predictors, using a multiple regression model (n = 140) were depression, income and number of children, those variables explaining 25.4% of variance.

    Nursing interventions that aim to enhance the family environment are necessary to help single-parent families with children to improve family functioning. The cultural and social factors that are unique to Japan's remote islands should be considered to assess the influence of this unique setting on family functioning. The objectives of this study were to evaluate the family functioning of child-rearing single-parent families living in different environments and to investigate the association between family demographics and family functioning. A self-administered questionnaire, the Japanese version of the Survey of Family Environment, was used to evaluate the sufficiency of family functioning. The participants were families with children enrolled in nurseries and kindergartens who were either living in remote, rural islands or in an urban city on the mainland in Japan. Family functioning was significantly higher for single-parent families living on the islands than for those living in the city in terms of media use, participation in community activities, and the collaboration of family members in child-rearing. Family functioning of single-parent families correlated significantly with household income, the parent's gender, family members' health, and family life cycle. Single-parent families living on Japanese offshore islands maintained family functioning through mutual support and the effective use of information technology. Nevertheless, single-parent families require additional support to improve their healthcare and financial situations.

    in promoting oxidative protein folding in the ER has been extended in recent years to include roles in other processes such as ER-associated degradation (ERAD), trafficking, calcium homeostasis, antigen presentation and virus entry. Some of these functions are performed by non-catalytic members of the family...... that lack the active-site cysteines. Regardless of their function, all human PDIs contain at least one domain of approximately 100 amino acid residues with structural homology to thioredoxin. As we learn more about the individual proteins of the family, a complex picture is emerging that emphasizes as much...... their differences as their similarities, and underlines the versatility of the thioredoxin fold.

    2014-01-01

    The number of multi-family housing complexes (MFHCs) over 15 yr old in South Korea is expected to exceed 5 million by 2015. Accordingly, the demand for energy retrofit in the deteriorating MFHCs is rapidly increasing. This study aimed to develop a decision support model for establishing the optimal energy retrofit strategy for existing MFHCs. It can provide clear criteria for establishing the carbon emissions reduction target (CERT) and allow efficient budget allocation for conducting the energy retrofit. The CERT for “S” MFHC, one of MFHCs located in Seoul, as a case study, was set at 23.0% (electricity) and 27.9% (gas energy). In the economic and environmental assessment, it was determined that scenario #12 was the optimal scenario (ranked second with regard to NPV 40 (net present value at year 40) and third with regard to SIR 40 (saving to investment ratio at year 40). The proposed model could be useful for owners, construction managers, or policymakers in charge of establishing energy retrofit strategy for existing MFHCs. It could allow contractors in a competitive bidding process to rationally establish the CERT and select the optimal energy retrofit strategy. It can be also applied to any other country or sector in a global environment. - Highlights: • The proposed model was developed to establish the optimal energy retrofit strategy. • Advanced case-based reasoning was applied to establish the community-based CERT. • Energy simulation was conducted to analyze the effects of energy retrofit strategy. • The optimal strategy can be finally selected based on the LCC and LCCO 2 analysis. • It could be extended to any other country or sector in the global environment

    Highlights: ► In the Nordic countries there is significant primary energy saving potential in single-family houses from 1970s. ► There are several behavioral, economical and market related hindrances to adoption of energy efficiency measures. ► One-stop-shop business models to offer full service energy renovation packages are slowly emerging. ► Marketing strategies and policy measures are required to promote full service energy renovation of single-family house. - Abstract: In Nordic countries significant primary energy saving potential exists in houses built before 1980. These old houses need to be renovated, which provides an opportunity for implementation of energy efficiency measures. However, there are several economic and market hindrances and the renovation markets are dominated by handicraft-based individual solutions. In this paper we have analyzed the opportunities for implementation of one-stop-shop business models where an overall contractor offers full-service renovation packages including consulting, independent energy audit, renovation work, follow-up (independent quality control and commissioning) and financing. A comparative assessment of emerging business models in the Nordic countries shows that different types of actors can provide such a service. Financing is included in some models. There are differences in how customers are contacted, while the similarities are on how the service is provided. Even though there is strong business potential for one-stop-shop energy renovation concept, still it has been somewhat difficult to start or run such a business. Various options to overcome the hindrances to promote energy efficient renovation of detached houses are discussed

  8. Family socioeconomic status and child executive functions: the roles of language, home environment, and single parenthood.

    The association between family socioeconomic status (SES) and child executive functions is well-documented. However, few studies have examined the role of potential mediators and moderators. We studied the independent and interactive associations between family SES and single parenthood to predict child executive functions of inhibitory control, cognitive flexibility, and working memory and examined child expressive language abilities and family home environment as potential mediators of these associations. Sixty families from diverse SES backgrounds with a school-age target child (mean [SD] age = 9.9 [0.96] years) were evaluated. Child executive functioning was measured using a brief battery. The quality of the home environment was evaluated using the Home Observation for the Measurement of the Environment inventory. Family SES predicted the three child executive functions under study. Single parent and family SES were interactively associated with children's inhibitory control and cognitive flexibility; such that children from low SES families who were living with one parent performed less well on executive function tests than children from similarly low SES who were living with two parents. Parental responsivity, enrichment activities and family companionship mediated the association between family SES and child inhibitory control and working memory. This study demonstrates that family SES inequalities are associated with inequalities in home environments and with inequalities in child executive functions. The impact of these disparities as they unfold in the lives of typically developing children merits further investigation and understanding.

    Objectives. We modeled rates of family and single-adult homelessness in the United States in metropolitan and nonmetropolitan regions and as a function of community-level demographic, behavioral, health, economic, and safety net characteristics. Methods. We entered community-level characteristics and US Department of Housing and Urban Development point-in-time counts for a single night in January 2009 into separate mixed-effects statistical analyses that modeled homelessness rates for 4 subpopulations: families and single adults in metropolitan and nonmetropolitan regions. Results. Community-level factors accounted for 25% to 50% of the variance in homelessness rates across models. In metropolitan regions, alcohol consumption, social support, and several economic indicators were uniquely associated with family homelessness, and drug use and homicide were uniquely associated with single-adult homelessness. In nonmetropolitan regions, life expectancy, religious adherence, unemployment, and rent burden were uniquely associated with family homelessness, and health care access, crime, several economic indicators, and receipt of Supplemental Security Income were uniquely associated with single-adult homelessness. Conclusions. Considering homeless families and single adults separately enabled more precise modeling of associations between homelessness rates and community-level characteristics, indicating targets for interventions to reduce homelessness among these subpopulations.

    2017-06-01

    To explore whether and how spatial aspects of children's hospital wards (single and shared rooms) impact upon family-centred care. Family-centred care has been widely adopted in paediatric hospitals internationally. Recent hospital building programmes in many countries have prioritised the provision of single rooms over shared rooms. Limited attention has, however, been paid to the potential impact of spatial aspects of paediatric wards on family-centred care. Qualitative, ethnographic. Phase 1; observation within four wards of a specialist children's hospital. Phase 2; interviews with 17 children aged 5-16 years and 60 parents/carers. Sixty nursing and support staff also took part in interviews and focus group discussions. All data were subjected to thematic analysis. Two themes emerged from the data analysis: 'role expectations' and 'family-nurse interactions'. The latter theme comprised three subthemes: 'family support needs', 'monitoring children's well-being' and 'survey-assess-interact within spatial contexts'. Spatial configurations within hospital wards significantly impacted upon the relationships and interactions between children, parents and nurses, which played out differently in single and shared rooms. Increasing the provision of single rooms within wards is therefore likely to directly affect how family-centred care manifests in practice. Nurses need to be sensitive to the impact of spatial characteristics, and particularly of single and shared rooms, on families' experiences of children's hospital wards. Nurses' contribution to and experience of family-centred care can be expected to change significantly when spatial characteristics of wards change and, as is currently the vogue, hospitals maximise the provision of single rather than shared rooms. © 2016 John Wiley & Sons Ltd.

    To evaluate the efficacy of ziv-aflibercept as a treatment for established corneal neovascularization (NV) and to compare its efficacy to that of bevacizumab following ocular chemical insult of sulfur mustard (SM) in the rabbit model. Chemical SM burn was induced in the right eye of NZW rabbits by vapor exposure. Ziv-aflibercept (2 mg) was applied once to neovascularized eyes by subconjunctival injection while subconjunctival bevacizumab (5 mg) was administered twice a week, for 3 weeks. Non-treated exposed eyes served as a control. A clinical follow-up employed by slit-lamp microscope, was performed up to 12 weeks following exposure and digital photographs of the cornea were taken for measurement of blood vessels length using the image analysis software. Eyes were taken for histological evaluation 2, 4 and 8 weeks following treatment for general morphology and for visualization of NV, using H&E and Masson Trichrome stainings, while conjunctival goblet cell density was determined by PAS staining. Corneal NV developed, starting as early as two weeks after exposure. A single subconjunctival treatment of ziv-aflibercept at 4 weeks post exposure, significantly reduced the extent of existing NV already one week following injection, an effect which lasted for at least 8 weeks following treatment, while NV in the non-treated exposed eyes continued to advance. The extensive reduction in corneal NV in the ziv-aflibercept treated group was confirmed by histological evaluation. Bevacizumab multiple treatment showed a benefit in NV reduction, but to a lesser extent compared to the ziv-aflibercept treatment. Finally, ziv-aflibercept increased the density of conjunctival goblet cells as compared to the exposed non-treated group. Subconjunctival ziv-aflibercept single treatment presented a highly efficient long-term therapeutic benefit in reducing existing corneal NV, following ocular sulfur mustard exposure. These findings show the robust anti-angiogenic efficacy of ziv

    African American youth from single-mother homes continue to be overrepresented in statistics on risk behavior and delinquency, a trend that many be attributed to father-absence, socioeconomic disadvantage, and compromises in parenting more typical of single than two-parent families. Yet, this risk-focused perspective ignores a long-standing strength of the African American community, the involvement and potential protective impact of extended family members in childrearing. This study describes the experiences of 95 African American single mothers and their nonmarital coparents who participated in a study of African American single-mother families with an 11-16-year-old child. Specifically, the study examines: (a) the extent to which nonmarital coparents are involved in childrearing; (b) the relative levels of risk (i.e., depression, mother-coparent conflict) and protective (i.e., parenting) associated with maternal and coparent involvement; and (c) how similarly and/or differently coparent and mother variables operate with regard to youth externalizing problems. Findings reveal that a range of family members and other adults actively participate in childrearing in African American single-mother families, coparents do not differ from mothers on certain study variables (i.e., depression and mother-coparent conflict) but do for others (parenting), and coparent involvement is associated with youth adjustment in ways that are similar to our more established understanding of maternal involvement. The potential clinical implications of the findings are discussed and future research directions are highlighted. © 2014 FPI, Inc.

    In South Asian countries like India, family system lays a strong foundation in societies and therefore, the context and consequences of single parent family structures are markedly different from that of the West. In these societies single parenthood is mainly an outcome of untimely death of any one of the parents. This study tried to examine the influence of parents' survival status on the mental health of youth in India. "Youth in India: situation and Needs (2006-2007)" survey data was used in the present study. We compared two groups of unmarried young population aged 15-24 y (n = 28 637): one having both parents alive and another having only one parent alive. Bivariate and multivariate techniques were applied to analyze the data. Results revealed that around 11% of the unmarried youth belonged to single parent families. Findings underscored a significant association between parent's survival and mental health of youth; respondents from single parent families were more likely to report metal health problems Moreover, effects of parents' survival were significant on females' mental health rather than males'. Policies must focus on reducing stress of young people growing up in single parent families through enhanced educational and employment opportunities.

  17. Quantifying riverine and storm-surge flood risk by single-family residence: application to Texas.

    2013-12-01

    The development of catastrophe models in recent years allows for assessment of the flood hazard much more effectively than when the federally run National Flood Insurance Program (NFIP) was created in 1968. We propose and then demonstrate a methodological approach to determine pure premiums based on the entire distribution of possible flood events. We apply hazard, exposure, and vulnerability analyses to a sample of 300,000 single-family residences in two counties in Texas (Travis and Galveston) using state-of-the-art flood catastrophe models. Even in zones of similar flood risk classification by FEMA there is substantial variation in exposure between coastal and inland flood risk. For instance, homes in the designated moderate-risk X500/B zones in Galveston are exposed to a flood risk on average 2.5 times greater than residences in X500/B zones in Travis. The results also show very similar average annual loss (corrected for exposure) for a number of residences despite their being in different FEMA flood zones. We also find significant storm-surge exposure outside of the FEMA designated storm-surge risk zones. Taken together these findings highlight the importance of a microanalysis of flood exposure. The process of aggregating risk at a flood zone level-as currently undertaken by FEMA-provides a false sense of uniformity. As our analysis indicates, the technology to delineate the flood risks exists today. © 2013 Society for Risk Analysis.

    The National Savings and Loan League (NSLL) has been researching techniques that may be used to finance energy-conservation measures in the residential sector. Twelve techniques developed and tested by NSLL are: future-advances clause under open-end mortgages; borrowing against existing savings accounts; home-improvement loans; variable-rate mortgages; second trusts or second mortgages; variable-payment mortgages; balloon-payment mortgages; deferred monthly payments for periods of excessive energy use; renegotiation of terms at set intervals; lower interest rates offered on mortgages in return for lender sharing in equity appreciation of the property; graduated payments; and deferred-interest loans. The testing took place in Pittsburgh, PA. The program consisted of 8 specific tasks, including several directed at different financial innovations for the financing of retrofits. Details are presented on findings; legal research; relationship of utilities to installation of retrofits; financing techniques applicable to retrofits; and national energy program for single-family residences. Some extensive attachments include information on: legal aspects, energy loan advertisements, and potential savings to be realized from various residential retrofit energy-conservation measures.

    Full Text Available The aim of the paper is a comparison of psychological readiness of the child to go to school in nuclear and single parent families. To obtain the objectives of the paper the following methods were used: 1 methods “Two schools” by L.A Venger to identify the level of formation of internal position of the student; 2 the method “Motivational research studies in older preschoolers” by M.R. Ginsburg; 3 method “Pattern” by L.I. Tsehanskaya to determine the degree of development of skills training activities; 4 method “Graphic dictation” by D. El’konin to study the ability to follow adult instructions. The investigated group consisted of 40 students from first grade secondary school - 20 students from nuclear families (12 girls and 8 boys and 20 students from single parent families (9 girls and 11 boys. As a result of qualitative, comparative and correlation analysis it was shown that readiness of children to go to school susbstantially depends on completness of their families. The children from families have a higher level of skill training and internal position than children from single parent families. This occurs because both parents pay more attention to the children in the forming of a willingness to learn in school. The studies have shown that in the group of children from nuclear families dominate the highest level of development of skills training activities, increased formation of internal positions and childrens social motivation. These indicators are the hallmarks of readiness to learn at school. Also, some recommendations to teachers are provided as for increase of motivation to learn in children from single parent families.

    To review the literature on teaching-skills training programs for family medicine residents and to identify formats and content of these programs and their effects. Ovid MEDLINE (1950 to mid-July 2008) and the Education Resources Information Center database (pre-1966 to mid-July 2008) were searched using and combining the MeSH terms teaching, internship and residency, and family practice; and teaching, graduate medical education, and family practice. The initial MEDLINE and Education Resources Information Center database searches identified 362 and 33 references, respectively. Titles and abstracts were reviewed and studies were included if they described the format or content of a teaching-skills program or if they were primary studies of the effects of a teaching-skills program for family medicine residents or family medicine and other specialty trainees. The bibliographies of those articles were reviewed for unidentified studies. A total of 8 articles were identified for systematic review. Selection was limited to articles published in English. Teaching-skills training programs for family medicine residents vary from half-day curricula to a few months of training. Their content includes leadership skills, effective clinical teaching skills, technical teaching skills, as well as feedback and evaluation skills. Evaluations mainly assessed the programs' effects on teaching behaviour, which was generally found to improve following participation in the programs. Evaluations of learner reactions and learning outcomes also suggested that the programs have positive effects. Family medicine residency training programs differ from all other residency training programs in their shorter duration, usually 2 years, and the broader scope of learning within those 2 years. Few studies on teaching-skills training, however, were designed specifically for family medicine residents. Further studies assessing the effects of teaching-skills training in family medicine residents are

    2017-03-01

    Parental involvement in keeping their children safe at work has been examined in a handful of studies, with mixed results. Evidence has suggested that non-work injury risk is higher among children from single-parent families, but little is known about their risk for work-related injuries. Five survey cycles of the Canadian Community Health Survey were pooled to create a nationally representative sample of employed 15-19-year old students (N = 16,620). Multivariable logistic regression estimated the association between family status and work injury. Risk of work-related repetitive strains (OR:1.24, 95%CI: 0.69-2.22) did not differ by family type. However, children of single parents were less likely to sustain a work injury receiving immediate medical care (OR:0.43, 95%CI: 0.19-0.96). Despite advantages and disadvantages related to family types, there is no evidence that work-related injury risk among adolescents from single parent families is greater than that of partnered-parent families.

    Generalized formula of the x-ray stress analysis for a single crystal with unknown stress-free lattice parameter was proposed. This method enables us to evaluate the plane stress states with any combination of diffraction planes. We can choose and combine the appropriate x-ray sources and diffraction plane families, depending on the sample orientation and the apparatus, whenever diffraction condition is satisfied. The analysis of plane stress distributions in an iron single crystal was demonstrated combining with the diffraction data for Fe{211} and Fe{310} plane families

    Short interspersed nuclear elements (SINEs) are non-long terminal repeat retrotransposons that are highly abundant, heterogeneous, and mostly not annotated in eukaryotic genomes. We developed a tool designated SINE-Finder for the targeted discovery of tRNA-derived SINEs. We analyzed sequence data of 16 plant genomes, including 13 angiosperms and three gymnosperms and identified 17,829 full-length and truncated SINEs falling into 31 families showing the widespread occurrence of SINEs in higher plants. The investigation focused on potato (Solanum tuberosum), resulting in the detection of seven different SolS SINE families consisting of 1489 full-length and 870 5' truncated copies. Consensus sequences of full-length members range in size from 106 to 244 bp depending on the SINE family. SolS SINEs populated related species and evolved separately, which led to some distinct subfamilies. Solanaceae SINEs are dispersed along chromosomes and distributed without clustering but with preferred integration into short A-rich motifs. They emerged more than 23 million years ago and were species specifically amplified during the radiation of potato, tomato (Solanum lycopersicum), and tobacco (Nicotiana tabacum). We show that tobacco TS retrotransposons are composite SINEs consisting of the 3' end of a long interspersed nuclear element integrated downstream of a nonhomologous SINE family followed by successfully colonization of the genome. We propose an evolutionary scenario for the formation of TS as a spontaneous event, which could be typical for the emergence of SINE families.

    Hereditary sensory and autonomic neuropathy type I (HSAN I) is an autosomal dominant disorder of the peripheral nervous system characterized by marked progressive sensory loss, with variable autonomic and motor involvement. The HSAN I locus maps to chromosome 9q22.1-22.3 and is caused by mutations in the gene coding for serine palmitoyltransferase long chain base subunit 1 (SPTLC1). Sequencing in HSAN I families have previously identified mutations in exons 5, 6 and 13 of this gene. Here we report the clinical, electrophysiological and pathological findings of a proband in a Chinese family with HSAN I. The affected members showed almost typical clinical features. Electrophysiological findings showed an axonal, predominantly sensory, neuropathy with motor and autonomic involvement. Sural nerve biopsy showed loss of myelinated and unmyelinated fibers. SPTLC1 mutational analysis revealed the C133W mutation, a mutation common in British HSAN I families.

    The need for energy retrofitting of the Danish single-family houses is massive, especially for the high proportion of single-family houses built in the 1960s and 1970s. But even though the potential benefits are many, only few families embark on a major energy retrofit. There may be many reasons...... for this. An obvious one may be limited knowledge of non-energy benefits, e.g. in relation to the indoor climate. The objective of this study was to explain this limited effort to save energy by identifying barriers and incentives among house owners in relation to energy retrofitting of one’s own house....... Moreover, it was investigated among house owners, who had carried out energy retrofitting, whether a number of factors, including the perceived indoor climate, became better or worse after retrofitting. A questionnaire survey was carried out among 1,990 house owners in a municipality north of Copenhagen...

  6. A guild of 45 CRISPR-associated (Cas protein families and multiple CRISPR/Cas subtypes exist in prokaryotic genomes.

    Directory of Open Access Journals (Sweden)

    Daniel H Haft

    2005-11-01

    Full Text Available Clustered regularly interspaced short palindromic repeats (CRISPRs are a family of DNA direct repeats found in many prokaryotic genomes. Repeats of 21-37 bp typically show weak dyad symmetry and are separated by regularly sized, nonrepetitive spacer sequences. Four CRISPR-associated (Cas protein families, designated Cas1 to Cas4, are strictly associated with CRISPR elements and always occur near a repeat cluster. Some spacers originate from mobile genetic elements and are thought to confer "immunity" against the elements that harbor these sequences. In the present study, we have systematically investigated uncharacterized proteins encoded in the vicinity of these CRISPRs and found many additional protein families that are strictly associated with CRISPR loci across multiple prokaryotic species. Multiple sequence alignments and hidden Markov models have been built for 45 Cas protein families. These models identify family members with high sensitivity and selectivity and classify key regulators of development, DevR and DevS, in Myxococcus xanthus as Cas proteins. These identifications show that CRISPR/cas gene regions can be quite large, with up to 20 different, tandem-arranged cas genes next to a repeat cluster or filling the region between two repeat clusters. Distinctive subsets of the collection of Cas proteins recur in phylogenetically distant species and correlate with characteristic repeat periodicity. The analyses presented here support initial proposals of mobility of these units, along with the likelihood that loci of different subtypes interact with one another as well as with host cell defensive, replicative, and regulatory systems. It is evident from this analysis that CRISPR/cas loci are larger, more complex, and more heterogeneous than previously appreciated.

There is a large potential for achieving energy savings in this sector, especially among the large number of single-family houses built in the 1960s and 1970s...... that the use of this approach produced a better renovation with a larger energy saving. The initial evaluation helped the house owners identify a maintenance backlog, and the use of an independent advisor helped ensure quality throughout the process. Renovations are too often carried out for just one purpose......: maintenance, to update functions or to reduce energy consumption. But a lot can be gained by combining these efforts, which can reduce expenses for planning and execution and avoid doing things twice.

    The advanced access (AA) model is a highly recommended innovation to improve timely access to primary healthcare. Despite that many studies have shown positive impacts for healthcare professionals, and for patients, implementing this model in clinics with a teaching mission for family medicine residents poses specific challenges. To identify these challenges within these clinics, as well as potential strategies to address them. The authors adopted a qualitative multiple case study design, collected data in 2016 using semi-structured interviews (N = 40) with healthcare professionals and clerical staff in four family medicine units in Quebec, and performed a thematic analysis. They validated results through a discussion workshop, involving many family physicians and residents practicing in different regions Results: Five challenges emerged from the data: 1) choosing, organizing residents' patient; 2) managing and balancing residents' appointment schedules; 3) balancing timely access with relational continuity; 4) understanding the AA model; 5) establishing collaborative practices with other health professionals. Several promising strategies were suggested to address these challenges, including clearly defining residents' patient panels; adopting a team-based care approach; incorporating the model into academic curriculum and clinical training; proactive and ongoing education of health professionals, residents, and patients; involving residents in the change process and in adjustment strategies. To meet the challenges of implementing AA, decision-makers should consider exposing residents to AA during academic training and clinical internships, involving them in team work on arrival, engaging them as key actors in the implementation and in intra- and inter-professional collaborative models.

  11. Detail, Facture, and Colour in the Architecture of Polish Single-Family Houses after 1989

    2017-10-01

    The article presents single-family houses architecture transformations since 1989, with particularly close attention paid to the significance of detail, facture, and colour. The article presents the architecture as an art of designing and building facilities with both use and aesthetic value, an art of shaping space and building forms. Architectural work should correspond to the intended function, technique, economic and aesthetic requirements, thus shaping all elements of human immediate environment, both inside and outside of the building. Architecture of the building is perceived as form, structure, and function, as well as detail, facture, and colour. Facture and colour are created through materials used for external finishes. The solid of the building is noticed first while looking at the building, then the finishes detail such as colour, facture, and detail. Materials for external finishes are commonly selected for their aesthetic value equally with their technical characteristics. The detail was always a characteristic element of style. However, currently the fashion for details can be observed, the fashion for usage of materials for external finishes and inter-connected with that colour and facture. The architecture of Polish single-family houses underwent considerable metamorphosis after system change of 1989 - from destitute in form, devoid in detail and colour socmodernism, to architecture extremely varied in terms of form, utilised structures, materials, and detail. Hence, appearance of the phenomenon called fashion can be observed in the architecture, understood as constant changeability, seeking novelty, and creation based on opinion-forming centres. The architectural fashion consists of form, function, structure, building materials, detail, facture, and colour trends, e.g. after rejecting socmodernism, steep roofs characteristic for single-family houses trend started. After 1989, initially individual single-family house projects were created; however

    Although research consistently suggests that adolescents in single-mother families are at increased risk for depression, the mechanisms that explain this relationship are unclear. In a community sample of adolescents (N = 368; ages 12-16; 50 % female; 50 % White) and their mothers (42 % single), adolescents completed measures of depressive symptoms, rumination, and depressogenic inferential style at baseline and two yearly follow-ups. Mothers reported on stressful events that occurred in the child's life from birth until baseline. Adolescents raised by single mothers, relative to partnered mothers, experienced more childhood stressors and higher rumination levels at 1-year follow-up. Additionally, higher rumination mediated the relationship between single motherhood and greater youth depressive symptoms at the 2-year follow-up. Clinical implications and developmental considerations are discussed.

    Based upon reflections from the Moynihan report of 1965, this author notes that the root causes of the growth in single-parent families have yet to be well identified, making it difficult to figure out where to go next. However, from 1965 onward, social policies have influenced the rate of growth in single-parent families. What is needed is a…

    The responses of single bullfrog olfactory neurons to various odorants were measured with the whole-cell patch clamp which offers direct information on cellular events and with the ciliary recording technique to obtain stable quantitative data from many neurons. A large portion of single olfactory neurons (about 64% and 79% in the whole-cell recording and in the ciliary recording, respectively) responded to many odorants with quite diverse molecular structures, including both odorants previously indicated to be cAMP-dependent (increasing) and independent odorants. One odorant elicited a response in many cells; e.g. hedione and citralva elicited the response in 100% and 92% of total neurons examined with the ciliary recording technique. To confirm that a single neuron carries different receptors or transduction pathways, the cross-adaptation technique was applied to single neurons. Application of hedione to a single neuron after desensitization of the current in response to lyral or citralva induced an inward current with a similar magnitude to that applied alone. It was suggested that most single olfactory neurons carry multiple receptors and at least dual transduction pathways.

  19. Out of the picture: a study of family drawings by children from step-, single-parent, and non-step families.

    Investigated the family drawings of 180 children ages 5 to 7 years in various family settings, including stepfather, single-parent, complex stepfamilies, and 2-parent control families. The relations of family type and biological relatedness to omission of family members and grouping of parents were examined. Children from step- and single-parent families were more likely to exclude family members than children from "control" non-step families, and exclusion was predicted from biological relatedness. Children who were biologically related to both resident parents were also more likely to group their parents together. Omission of family members was found to be associated with children's adjustment (specifically more externalizing and internalizing behavior) as reported by teachers and parents. The results indicate that biological relatedness is a salient aspect of very young children's representations of their families. The association between adjustment and exclusion of family members and grouping of parents indicates that family drawings may be useful research and clinical tools, when used in combination with other methods of assessment.

  20. Comparison of adolescents' perceptions and behaviors in single- and two-parent families.

    1980-10-01

    This study investigated the self-concepts, school achievement, occupational aspirations, vocational maturity, and perceptions of parents of children from two-parent and single-parent homes. The sample contained 559 children, 19% from single-parent homes. A multivariateF indicated children from two-parent homes had significantly higher school grades and occupational aspirations. There were also significant differences in children's perceptions of relationships with fathers, but not with mothers. It was argued that family structure has an impact on adolescents' perceptions and behaviors.

    Germline mutations are responsible for familial cancer syndromes which account for approximately 5-10% of all types of cancers. These mutations mainly occur at tumor suppressor genes or genome stability genes, such as DNA repair genes. Here we have identified a cancer predisposition family, in which eight members were inflicted with a wide spectrum of cancer including one diagnosed with lung cancer at 22years old. Sequencing analysis of tumor samples as well as histologically normal specimens identified two germline mutations co-existing in the familial cancer syndrome, the mutation of tumor suppressor gene P53 V157D and mismatch repair gene PMS2 R20Q. We further demonstrate that P53 V157D and/or PMS2 R20Q mutant promotes lung cancer cell proliferation. These two mutants are capable of promoting colony formation in soft agar as well as tumor formation in transgenic drosophila system. Collectively, these data have uncovered the important role of co-existing germline P53 and PMS2 mutations in the familial cancer syndrome development. Copyright © 2013 Elsevier Ireland Ltd.

    Land cover composition is a valuable indicator of the ecological performance of a city. Single-family housing areas constitute a substantial part of most cities and may as such play an important role for sustainable urban development. From aerial photos we performed detailed GIS-based mapping...... of land cover in three detached single-family housing areas in Denmark of different urban form but comparable housing densities (ranging from 10.0 to 11.3 houses per hectare). The findings were subjected to statistical analysis and landscape metrics. Land cover varied with urban form: A traditional...... spatial configuration with rectangular parcels contained significantly more vegetation and less impervious surfaces per parcel than newer Radburn-inspired configurations with more quadratic parcels. Correlation analysis showed size of paved access ways to be positively correlated with distance from road...

    Whereas many studies have investigated quantitative aspects of book reading (frequency), few have examined qualitative aspects, especially in very young children and through direct observations of shared reading. The purpose of this study was to determine possible differences in book-reading styles between mothers and fathers and between mothers from single- and dual-parent families. It also related types of parental verbalizations during book reading to children's reported language measures. Dual-parent (29) and single-parent (24) families were observed in shared book reading with their toddlers (15-month-olds) or young preschoolers (27-month-olds). Parent-child dyads were videotaped while book reading. The initiator of each book-reading episode was coded. Parents' verbalizations were exhaustively coded into 10 categories. Mothers completed the MacArthur Communicative Development Inventory, and the children were given the Bayley scales. All parents differentiated their verbalizations according to the age rather than the gender of the child, but single mothers imitated female children more than males. Few differences in verbalizations were found between mothers and fathers or between mothers from single- and dual-parent families. Fathers allowed younger children to initiate book-reading episodes more than mothers. For both age groups of children, combined across families, verbalizations that related the book to the child's experience were correlated with reported language measures. Questions and imitations were related to language measures for the older age group. The important types of parental verbalizations during shared book reading for children's language acquisition are relating, questions and imitations.

    This study aimed to explore attitudes towards family formation in single or cohabiting childless women of advanced age. The design comprised semi-structured qualitative interviews of 20 women aged 34-39 years attending the Fertility Assessment and Counselling Clinic, Rigshospitalet, Copenhagen. A sample of 10 single women and 10 cohabiting women was chosen with equal distribution of postgraduate education length. Data were analysed using content analysis following the method of Graneheim and Lundman and consolidated criteria for reporting qualitative research (COREQ). The general attitude towards family formation was characterized by a fear of the consequences of choosing motherhood on one hand, and a 'ticking biological clock' and a wish to establish a nuclear family on the other. The women idealized the perception of perfect mothering in terms of uncompromising expectations of child rearing and showed an increasing awareness of solo motherhood as a possible solution to advanced age, the wish of a child and single status compared to earlier studies. Our study contributes to knowledge and understanding of personal considerations related to childbearing in nullipara women in their mid- to late 30s and may be useful in a fertility assessment and counselling setting.

    To investigate the relationships between symptoms compatible with the sick building syndrome (SBS) in adults and building dampness and ventilation in single-family houses. Within the Swedish BETSI study, a national sample of single-family houses were inspected by professional building experts, and adults living in the houses answered a questionnaire on SBS. Relationships between building factors and SBS were analysed using logistic regression. Of the respondents, 23% reported having had weekly SBS symptoms during the last three months. A large proportion of houses exhibited building or construction problems. In total, 40% of houses had dampness problems in the foundation, and this was related to a higher prevalence of both mucous and dermal symptoms, and any SBS symptoms. Furthermore, high air humidity was related to more symptoms, with the relationship with absolute humidity being stronger than that with relative humidity or moisture load. Symptoms were also more prevalent in houses with a high U value, reflecting a poor thermal insulation. Compared to natural ventilation, living in a house with mechanical supply and exhaust ventilation was related to a lower prevalence of general symptoms and any SBS symptoms, but there were only weak associations between measured air exchange rate and symptoms. A large proportion of single-family houses have dampness problems in the foundation, and pollutants may enter the living space of the house and affect the health of the occupants. Furthermore, absolute air humidity should be measured more often in indoor air studies.

    The crude divorce rate has been increasing steadily for over a decade in China. Consequently, more and more children have to face the challenge of growing up in single parent families. The current study investigated the mediating effects of problem-oriented and emotion-oriented coping on the relationship between parental attachment and psychological resilience among a sample of Chinese adolescents from single parent families and intact families. Participants were 975 high school students (44.30% males; aged 15-19 years, M = 16.32 years, SD = 0.74), 871 from intact families and 104 from single parent families. Structural equation modeling showed that security in maternal attachment was positively associated with resilience through the indirect effect of reduced emotion-oriented coping among adolescents from single parent families. Among adolescents from intact families, security in maternal attachment was both directly associated with resilience and indirectly through enhanced problem-oriented and reduced emotion-oriented coping. Security in paternal attachment was associated with resilience both directly and indirectly through enhanced problem-oriented coping as well among those from intact families. Female adolescents exhibited significantly lower levels of resilience than male adolescents did regardless of the marital status of their parents. Limitations and suggestions for future research are discussed.

    2012-01-01

    BACKGROUND This paper explores recent developments in female contraception, using them to illustrate how adaptation of existing methods, improved service delivery and understanding contraceptive behaviour might increase contraceptive uptake and correct and consistent use, and how the development of new methods holds some promise for capitalizing on the potential non-contraceptive benefits. METHODS Searches were performed in Medline and other databases. Selection criteria included high-quality studies and studies relevant to clinical reproductive medicine. Summaries were presented and discussed by the European Society of Human Reproduction and Embryology (ESHRE) Workshop Group. RESULTS The topics discussed include: adapted regimens for combined oral contraceptive pills, non-invasive methods of female sterilization, the need to improve the awareness of pregnancy risk to increase the use of emergency contraception, improvements in the evidence base for the safety and service delivery of intrauterine methods, emphasis on the potential benefits of combined oral contraceptives for women with hirsutism and acne, the potential of female sterilization to prevent ovarian cancer, and the promise of anti-progesterones and new approaches to dual protection. CONCLUSIONS Although great strides have been made in recent years in increasing contraceptive use among women in many countries where contraceptive prevalence is low or there is a high unmet need for contraception, much more can, and needs to, be done.

We also provide a list of families of aquatic insects in Latin America, with an initial assignment to FFGs. We recommended caution when assigning FFGs based on gut contents, as it can provide misleading information. Overall, FFG is a very useful tool to understand the role of aquatic macroinvertebrates in stream ecosystems and comparisons among studies will benefit from consistency in their use. Rev. Biol.

    Full Text Available This study explored the experiences of work-family conflict amongst a group of twenty single working mothers with pre-school age children. Dubin’s (1992 theory of Central Life Interests was utilised to fully understand how the differential importance of the roles played by the women informed the level and nature of the conflict experienced. A two-phase research design was employed in which questionnaire responses from the first phase formed the basis for the second phase of in-depth qualitative interviews. Results indicated that participants viewed motherhood as their Central Life Interest and that this priority could lead them to experience greater conflict between work and family demands. Although work was rated second in importance when compared to family, it was still seen as being of great significance, not only for instrumental reasons, but also for the intellectual stimulation that it provided and opportunities to exercise independence and responsibility. Opsomming Die werk-en-familie konflik-ervarings van twintig werkende enkel-moeders met voorskoolse kinders is ondersoek in hierdie projek. Dubin (1992 se teorie van sentrale lewensbelangstellings is gebruik om te bepaal hoe die belangrikheid van die twee rolle die vlak en aard van die konflik bepaal het. Die navorsing is in twee fases gedoen: ‘n vraelys in die eerste fase, opgevolg deur in-diepte kwalitatiewe onderhoude. Resultate het gewys dat die deelnemers moederskap as hul sentrale lewensbelangstelling beskou het, en dat hierdie prioriteit kon lei tot groter konflik tussen die eise van werk en familie. Alhoewel werk as ondergeskik aan familie beoordeel is, was dit nogtans van groot belang. Aan die een kant was dit vir instrumentele redes, maar dit het ook intellektuele stimulasie verskaf en geleenthede gegee om onafhanklik en verantwoordelik op te tree.

  15. Design architecture for multi-zone HVAC control systems from existing single-zone systems using wireless sensor networks

    Redfern, Andrew; Koplow, Michael; Wright, Paul

    2007-01-01

    Most residential heating, ventilating, and air-conditioning (HVAC) systems utilize a single zone for conditioning air throughout the entire house. While inexpensive, these systems lead to wide temperature distributions and inefficient cooling due to the difference in thermal loads in different rooms. The end result is additional cost to the end user because the house is over conditioned. To reduce the total amount of energy used in a home and to increase occupant comfort there is a need for a better control system using multiple temperature zones. Typical multi-zone systems are costly and require extensive infrastructure to function. Recent advances in wireless sensor networks (WSNs) have enabled a low cost drop-in wireless vent register control system. The register control system is controlled by a master controller unit, which collects sensor data from a distributed wireless sensor network. Each sensor node samples local settings (occupancy, light, humidity and temperature) and reports the data back to the master control unit. The master control unit compiles the incoming data and then actuates the vent resisters to control the airflow throughout the house. The control system also utilizes a smart thermostat with a movable set point to enable the user to define their given comfort levels. The new system can reduce the run time of the HVAC system and thus decreasing the amount of energy used and increasing the comfort of the home occupations.

  16. Effects of workplace, family and cultural influences on low back pain: what opportunities exist to address social factors in general consultations?

    Shaw, William S; Campbell, Paul; Nelson, Candace C; Main, Chris J; Linton, Steven J

    2013-10-01

    Social factors are widely acknowledged in behavioural models of pain and pain management, but incorporating these factors into general medical consultations for low back pain (LBP) can be challenging. While there is no compelling evidence that social factors contribute to LBP onset, these factors have been shown to influence functional limitation and disability, especially the effects of organisational support in the workplace, spousal support, family conflict and social disadvantage. A number of barriers exist to address such social factors in routine medical encounters for LBP, but there is emerging evidence that improving social and organisational support may be an effective strategy to reduce the negative lifestyle consequences of LBP. For clinicians to address these factors in LBP treatment requires a clearer psychosocial framework in assessment and screening, more individualised problem-solving efforts, more patient-centred interventions involving family, peers and workplace supports and a less biomechanical and diagnostic approach.

  17. Female-partnered and single women's contact motivations and experiences with donor-linked families.

    2015-06-01

    What are female-partnered and single mothers' motivations and experiences at one donor insemination (DI) program with regard to contacting other families who share the same sperm donor? By and large, women reported seeking contact to obtain (i) support for their children and/or themselves, and (ii) information about shared traits and medical problems, ultimately describing a range of contact experiences, both positive (e.g. special bond created) and negative (e.g. uncomfortable encounters). There is a growing phenomenon of donor insemination families-parents and/or offspring-seeking others who share their donor (i.e. are 'donor-linked'). There is limited understanding about parental motivations and experiences-especially in the presence of a second parent-due to the methodological constraints of previous quantitative studies. Semi-structured telephone interviews were conducted with 50 donor insemination mothers (14 single, 36 female-partnered). Participants were recruited by email invitation to parent members of a family-matching service at one donor insemination program in the USA. The criterion for inclusion was having matched to at least one donor-linked family. Among the 50 mothers interviewed, all had at least one child conceived via donor insemination, who was between ages 0 and 15 years at first contact. Families matched with a median of three donor-linked families (range 1-10). Interview data were analyzed through qualitative (i.e. thematic) analysis. Overarching themes emerged of seeking contact to obtain (i) support and (ii) information about children's shared physical and psychological traits. Some wanted to increase their child's family network, through adding a sibling, but more often as extended family. Data, from partnered parents especially, revealed the challenges of balancing the boundaries of family formed without the genetic link with the perceived benefits of exploring the child's donor origins. Interviews focused on openness and information

    2017-01-04

    This study investigated the extent to which single mothers of children with atopic eczema experience disease-related stress. A total of 96 mothers were divided into 4 groups: mothers living with a partner, who had or did not have a child with atopic eczema, and single mothers, who had or did not have a child with atopic eczema. The following questionnaires were used to assess psychological burden: Short Stress Questionnaire (Kurzer Fragebogen zur Erfassung von Belastung; KFB), Satisfaction with Life Questionnaire (Fragebogen zur Lebenszufriedenheit; FLZ), General Depression Scale (Allgemeine Depressions-Skala; ADS), and the Questionnaire for Parents of Children with Atopic Eczema (Fragebogen für Eltern von Neurodermitis kranken Kindern; FEN). Single mothers had higher levels of helplessness and aggression due to their child's scratching behaviour than did mothers living with a partner and a child with atopic eczema. Single mothers of children with atopic eczema had the highest scores regarding experienced stress in the family and the lowest scores concerning general life satisfaction. Special care should be provided for single mothers with higher stress, in order to teach them how to deal with the scratching behaviour of their children.

    The quality of the environment is an essential point in the care of preterm newborns. The design of neonatal intensive care units (NICUs) (open-bay, single-patient room, single-family room) directly affects both the preterm newborns and their caregivers (parents, healthcare staff). The aim of this systematic review was to evaluate the impact of single-family rooms on the preterm newborn, its parents, and the staff. Single-family rooms improve outcome for the preterm newborn, with increasing parental involvement and better control of the environment (fewer inappropriate stimulations such as high levels of noise and illumination). This kind of NICU design also improves parental and staff satisfaction. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Preterm infants are at an increased risk for neurodevelopmental delay. They have to endure many stressors in early life, including parent-infant separation, noise and painful procedures during hospitalisation in the highly technological environment of the modern neonatal ward. Currently, a shift is being noticed in the architectural design of neonatal wards towards single family rooms instead of the common open bay units. The influence of the hospital environment on health and specifically neurodevelopment in this vulnerable patient population remains under discussion. To assess the effect of single family rooms during hospitalisation primarily on neurodevelopment in preterm infants. Secondary outcome measures will be neonatal (ie, breastfeeding rates, sepsis, growth during hospital stay, length of hospital stay) and parental (ie, parental stress, satisfaction, participation, presence and self-efficacy). The PRISMA-P 2015 (Preferred Reporting Items for Systematic reviews and Meta-Analyses for Protocols 2015) 17 items checklist was used for the generation of the protocol for this review. The following PICO was formulated: Population: preterm infants with need of hospitalisation in the neonatal ward; Intervention: single family rooms; Comparison: standard neonatal care in open bay units; Outcome: neurodevelopmental outcome of infants from 9 months onwards. If at least two studies, with low or moderate risk of bias, suitable for inclusion are found a meta-analysis will be performed. If quantitative synthesis is not appropriate the data will be presented descriptively. This will be the first review, systematically assessing the effect of single family rooms on neurodevelopmental outcome in preterm infants. Clinical practice could possibly be optimised to ameliorate neurodevelopment in this vulnerable patient population based on these insights. This systematic review will be published in an international peer-reviewed journal. We registered this systematic review

  1. On the thermal inertia and time constant of single-family houses

    Energy Technology Data Exchange (ETDEWEB)

    Hedbrant, J.

    2001-08-01

    Since the 1970s, electricity has become a common heating source in Swedish single-family houses. About one million small houses can use electricity for heating, about 600.000 have electricity as the only heating source, A liberalised European electricity market would most likely raise the Swedish electricity prices during daytime on weekdays and lower it at other times. In the long run, electrical heating of houses would be replaced by fuels, but in the shorter perspective, other strategies may be considered. This report evaluates the use of electricity for heating a dwelling, or part of it, at night when both the demand and the price are low. The stored heat is utilised in the daytime some hours later, when the electricity price is high. Essential for heat storage is the thermal time constant. The report gives a simple theoretical framework for the calculation of the time constant for a single-family house with furniture. Furthermore the comfort time constant, that is, the time for a house to cool down from a maximum to a minimum acceptable temperature, is derived. Two theoretical model houses are calculated, and the results are compared to data from empirical studies in three inhabited test houses. The results show that it was possible to store about 8 kWh/K in a house from the seventies and about 5 kWh/K in a house from the eighties. The time constants were 34 h and 53 h, respectively. During winter conditions with 0 deg C outdoor, the 'comfort' time constants with maximum and minimum indoor temperatures of 23 and 20 deg C were 6 h and 10 h. The results indicate that the maximum load-shifting potential of an average single family house is about 1 kw during 16 daytime hours shifted into 2 kw during 8 night hours. Upscaled to the one million Swedish single-family houses that can use electricity as a heating source, the maximum potential is 1000 MW daytime time-shifted into 2000 MW at night.

  2. Automatic single questionnaire intensity (SQI, EMS98 scale) estimation using ranking models built on the existing BCSF database

    2013-12-01

    In charge of intensity estimations in France, BCSF has collected and manually analyzed more than 47000 online individual macroseismic questionnaires since 2000 up to intensity VI. These macroseismic data allow us to estimate one SQI value (Single Questionnaire Intensity) for each form following the EMS98 scale. The reliability of the automatic intensity estimation is important as they are today used for automatic shakemaps communications and crisis management. Today, the automatic intensity estimation at BCSF is based on the direct use of thumbnails selected on a menu by the witnesses. Each thumbnail corresponds to an EMS-98 intensity value, allowing us to quickly issue an intensity map of the communal intensity by averaging the SQIs at each city. Afterwards an expert, to determine a definitive SQI, manually analyzes each form. This work is time consuming and not anymore suitable considering the increasing number of testimonies at BCSF. Nevertheless, it can take into account incoherent answers. We tested several automatic methods (USGS algorithm, Correlation coefficient, Thumbnails) (Sira et al. 2013, IASPEI) and compared them with 'expert' SQIs. These methods gave us medium score (between 50 to 60% of well SQI determined and 35 to 40% with plus one or minus one intensity degree). The best fit was observed with the thumbnails. Here, we present new approaches based on 3 statistical ranking methods as 1) Multinomial logistic regression model, 2) Discriminant analysis DISQUAL and 3) Support vector machines (SVMs). The two first methods are standard methods, while the third one is more recent. Theses methods could be applied because the BCSF has already in his database more then 47000 forms and because their questions and answers are well adapted for a statistical analysis. The ranking models could then be used as automatic method constrained on expert analysis. The performance of the automatic methods and the reliability of the estimated SQI can be evaluated thanks to

    radiator sizes and heating demands in 4 existing Danish single-family houses from the 1930s. A year-long dynamic simulation was performed for each of the houses to evaluate the potential to lower the heating system temperatures. The results indicate that there is a large potential to use low......-temperature district heating in existing single-family houses. In order to obtain the full potential of low-temperature district heating, critical radiators must be replaced. Based on a novel method, a total of nine radiators were identified to be critical to ensure thermal comfort and low return temperatures in two...

    There is a high and increasing proportion of single-parent families in Jamaica. This has raised concerns about the potential impact of single-parent families on the social, cognitive and behavioural development of children, including their sexual relationships. The aim of this study was to investigate the association between being raised in a single-parent family and age of sexual debut among young people in Jamaica. The study was cross-sectional in design, and based on a multi-stage sampling procedure. The study was conducted in July/September 2016. The study sample comprised 233 respondents (110 males and 123 females) aged from 18 to 35 years (mean 26.37 years; SD 5.46). Respondents completed a self-administered questionnaire with questions on socio-demographic characteristics, family structure, sexual debut and current sexual behaviour. Ninety-seven (41.7%) respondents grew up in single-parent families. A total of 201 (86.3%) had had sex (102 males and 99 females). Their mean age of sexual debut was 15.51 years (SD 3.41). Sixty-five (32.3%) had early sexual debut (single-parent families were more likely to have had early sexual debut (56.9%; n=37) compared with those from two-parent families (43.1%, n=28; p=0.004). Only 44.6% (n=29) of those who experienced early sexual debut used a condom during their first sexual encounter compared with 73% (n=100) of those who had a later sexual debut (≥16 years; p=single-father family structure was a significant predictor of early sexual debut (AOR 5.5; 95%CI: 1.1-25.8). The study found a significant association between single-parent family structure and age of sexual debut.

    Typical approaches for assessing energy efficiency potential in buildings use a limited number of prototypes, and therefore suffer from inadequate resolution when pass-fail cost-effectiveness tests are applied, which can significantly underestimate or overestimate the economic potential of energy efficiency technologies. This analysis applies a new approach to large-scale residential energy analysis, combining the use of large public and private data sources, statistical sampling, detailed building simulations, and high-performance computing to achieve unprecedented granularity - and therefore accuracy - in modeling the diversity of the single-family housing stock. The result is a comprehensive set of maps, tables, and figures showing the technical and economic potential of 50 plus residential energy efficiency upgrades and packages for each state. Policymakers, program designers, and manufacturers can use these results to identify upgrades with the highest potential for cost-effective savings in a particular state or region, as well as help identify customer segments for targeted marketing and deployment. The primary finding of this analysis is that there is significant technical and economic potential to save electricity and on-site fuel use in the single-family housing stock. However, the economic potential is very sensitive to the cost-effectiveness criteria used for analysis. Additionally, the savings of particular energy efficiency upgrades is situation-specific within the housing stock (depending on climate, building vintage, heating fuel type, building physical characteristics, etc.).

    2015-01-01

    This exploratory research brief presents a single case study of the resiliency of "Mary B." She grew up in an Old Order Amish family where isolation, secrecy, and patriarchy masked repeated sexual assaults by her older brothers that began at age 7. By the age of 20, Mary alleged she had been raped on more than 200 separate occasions by members of her Amish family. After years of pleading with her mother and church officials to intervene, she sought therapy outside the Amish community. This led to three of her brothers being incarcerated. Her family disowned her and she was banned from the Amish community, leaving with an 8th grade education and little more than the clothes she was wearing. In less than 2 years, Mary had moved to a new town, completed her GED, obtained a car and driving license, maintained a small home, and worked as a certified nursing assistant. She consented to tape recorded interviews and completed several quantitative diagnostic measures. Scores on the diagnostic measures placed her within the normal range on self-esteem, competency, depression, stress, social support, and life skills. Analysis of interviews revealed Mary rebounded from her past by reframing her experiences. Themes identified within the interviews supported 6 of the 7 types of resiliencies (insight, independence, initiative, relationships, humor, and morality) outlined in the therapeutic Challenge Model.

    The aim of this study was to examine the potential relationship between Jamaican secondary students’ alcohol drinking habits and their family structure. Methods: Data collected from a nationally representative survey of 3,365 students were analysed. Descriptive and inferential statistics were performed. Results: Out of the 3,365 students, 1,044 (31.0%) were from single-parent families. Single-parent families, married-parent families and common law-parent families were significantly associated with lifetime use of alcohol (AOR= 1.72, 95% CI= 1.06 - 2.79; AOR= 1.73, 95% CI= 1.07- 2.81, AOR= 1.94, 95%CI= 1.17- 3.21 respectively). However, family structure was not significantly associated with past year and past month alcohol use. Students whose parents “sometimes” knew their whereabouts were significantly less likely to use alcohol in their lifetime compared to students whose parents “Always” knew where the students were. Conclusion: Family structure is an independent predictor of alcohol use among high school students in Jamaica. Being from single-parent families, married-parent and common- law parent families were significantly associated with increased likelihood for lifetime alcohol use.

    Full Text Available Background and Purpose: Family is the first and the most important structure in human civilization in which social lifestyles, mutual understanding, and compatibility is learned. Studies have shown that parenting style, is one the most important and fundamental factors in personality development. The purpose of this study was comparison of parenting style in single child and multiple children families. Materials and Methods: This study, in total, 152 mothers from Andimeshk city, Iran, were selected by random sampling. Data were collected from a health-care center was chosen randomly, mothers who had 5-7 years old children were enrolled in this study. The data collecting tool was the questionnaire which investigates permissive, authoritative, and authoritarian parenting styles in parents. After data entry in SPSS software, the collected data were analyzed by ANOVA, independent t-test, and Pearson correlation test. Results: The mean age of the participants was 32.71 ± 5.39 years old participated in this study. 69 mothers (45.4% had one child, 53 (34.9% had 2 children, and 30 mothers (19.7% had 3 and more children. The mean score of permissive parenting style was 19.97 ± 5.13 in single child families; the mean score of authoritative (19.56 ± 4.70 and authoritarian parenting style (34.50 ± 2.81 that difference was significantly (P < 0.050. Conclusion: According to the results of this study, it seems that having more children would make parents more logical and paves the way for upbringing children. Therefore, it is recommended to plan some educational programs about this issue for parents.

    2009-12-01

    In this paper, we advance and test an integrative model of the effects of employment status, nonstandard work schedules, male employment, and women's perceptions of economic instability on union formation among low-income single mothers. Based on longitudinal data from 1,299 low-income mothers from the 3-city Welfare Study, results indicate that employment status alone is not significantly associated with whether women marry or cohabit. We find that nonemployed mothers and mothers working nonstandard schedules were less likely to marry compared to those working standard schedules. Mothers' perceptions of economic well-being were associated with marriage at Wave 2. In contrast, cohabitation outcomes were not explained by economic factors, but were related to the perception of child care support. The policy implications of these results are discussed, in particular, as they relate to welfare reform's work and family goals.

    The first family of rare-earth-based single chain magnets is presented. Compounds of general formula [M(hfac)3(NITPhOPh)], where M = Eu, Gd, Tb, Dy, Ho, Er, or Yb, and PhOPh is the nitronyl-nitroxide radical (2,4'-benzoxo-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide), have been structurally characterized and found to be isostructural. The characterization of both static and dynamic magnetic properties of the whole family is reported. Dy, Tb, and Ho compounds display slow relaxation of the magnetization, and ac susceptibility shows a thermally activated regime with energy barriers of 69, 45, and 34 K for Dy, Tb, and Ho compounds, respectively, while only a frequency-dependent susceptibility is observed for Er below 2.0 K. In Gd and Yb derivatives, antiferromagnetic interactions dominate. The pre-exponential factors differ by about 4 orders of magnitude. Finite size effects, due to naturally occurring defects, affect the static and dynamic properties of the compounds differently.

    Full Text Available Mercury pollution (MeHg up the aquatic food chains in the Amazonian ecosystems has been a major concern in environmental health. Riverside people (ribeirinhos along the Upper Madeira river are heavy fish eaters. Hair is the best biomarker for MeHg exposure. By assuming a constant hair growth rate, it is possible to evaluate a temporal profile of Hg exposure over the recent defined past. In this paper we present the segmental total hair Hg concentrations from a single family from which some of the 10 persons investigated had high hair Hg concentrations (peak of 339 ppm. We also presented the hair MeHg content from 4 out of the 10 family members investigated. There was a wide variation in total hair Hg concentrations (8 to 339 ppm among these individuals, who were mostly sharing their meals; there was also a wide variation in total Hg concentrations in the same individual over time (136 to 274 ppm. Hg speciation showed a mean and standard deviation in the MeHg content of 62% and 6%, respectively. The wide variation in total hair Hg concentration strongly indicated that it is possible to mitigate critical Hg exposure levels by conducting a fish advisory.

    In this study we investigate whether there are differences between adolescents who grow up in single-parent families and those who grow up in nucleus families. We have decided that there are no differences in the physical development between the adolescents who are growing up in single parent families and those growing up in nucleus families. There is no difference in the self-concept between these two groups, except in the ethical and moral self-image of adolescents living with one parent. Adolescents living in single-parent families have a weaker moral self-image. It can thus be concluded that physical development and positive self-concept (a favorable image of oneself) in adolescents do not depend on whether an adolescent is growing up in a single-parent or a nucleus family, but on the different characteristics of parents and their relationship with children, whether they are married or not. For the children development the best is healthy marriage of their parents.

    2015-01-01

    African American youth from single mother homes continue to be overrepresented in statistics on risk behavior and delinquency, a trend that many be attributed to father-absence, socioeconomic disadvantage, and compromises in parenting more typical of single than two-parent families. Yet, this risk-focused perspective ignores a long-standing strength of the African American community, the involvement and potential protective impact of extended family members in childrearing. This study describes the experiences of 95 African American single mothers and their non-marital coparents who participated in a study of African American single mother families with an 11 to 16 year old child. Specifically, the study examines: 1) the extent to which nonmarital coparents are involved in childrearing; 2) the relative levels of risk (i.e., depression, mother-coparent conflict) and protective (i.e., parenting) associated with maternal and coparent involvement; and 3) how similarly and/or differently coparent and mother variables operate with regard to youth externalizing problems. Findings reveal that a range of family members and other adults actively participate in childrearing in African American single mother families, coparents do not differ from mothers on certain study variables (i.e., depression and mother-coparent conflict) but do for others (parenting), and coparent involvement is associated with youth adjustment in ways that are similar to our more established understanding of maternal involvement. The potential clinical implications of the findings are discussed and future research directions are highlighted. PMID:24479612

    Especially for single older adults with chronic diseases, physical inactivity and a poor social network are regarded as serious threats to their health and independence. The Active Plus intervention is an automated computer-tailored eHealth intervention that has been proven effective to promote physical activity (PA) in the general population of adults older than 50 years. The aim of this study was to report on the methods and results of the systematic adaptation of Active Plus to the wishes and needs of the subgroup of single people older than 65 years who have one or more chronic diseases, as this specific target population may encounter specific challenges regarding PA and social network. The Intervention Mapping (IM) protocol was used to systematically adapt the existing intervention to optimally suit this specific target population. A literature study was performed, and quantitative as well as qualitative data were derived from health care professionals (by questionnaires, n=10) and the target population (by focus group interviews, n=14), which were then systematically integrated into the adapted intervention. As the health problems and the targeted behavior are largely the same in the original and adapted intervention, the outcome of the needs assessment was that the performance objectives remained the same. As found in the literature study and in data derived from health professionals and focus groups, the relative importance and operationalization of the relevant psychosocial determinants related to these objectives are different from the original intervention, resulting in a refinement of the change objectives to optimally fit the specific target population. This refinement also resulted in changes in the practical applications, program components, intervention materials, and the evaluation and implementation strategy for the subgroup of single, chronically impaired older adults. This study demonstrates that the adaptation of an existing intervention is an

    This study aimed to evaluate the effects of the gender-role types and child-rearing gender-role attitude of the single-parents, as well as their children's gender role traits and family socio-economic status, on social adjustment. We recruited 458 pairs of single parents and their children aged 8-18 by purposive sampling. The research tools included the Family Socio-economic Status Questionnaire, Sex Role Scales, Parental Child-rearing Gender-role Attitude Scale and Social Adjustment Scale. The results indicated: (a) single mothers' and their daughters' feminine traits were both higher than their masculine traits, and sons' masculine traits were higher than their feminine traits; the majority gender-role type of single parents and their children was androgyny; significant differences were found between children's gender-role types depending on different raiser, the proportion of girls' masculine traits raised by single fathers was significantly higher than those who were raised by single mothers; (b) family socio-economic status and single parents' gender-role types positively influenced parental child-rearing gender-role attitude, which in turn, influenced the children's gender traits, and further affected children's social adjustment. © 2018 International Union of Psychological Science.

  6. No More Second-Class Taxpayers: How Income Splitting Can Bring Fairness to Canada’s Single Income Families

    Directory of Open Access Journals (Sweden)

    Matt Krzepkowski

    2013-04-01

    Full Text Available The Canadian personal income tax system does not pay much attention to whether the amount of money an individual brings home is supplemented by the income of a spouse or not. That means that families where one spouse earns more than the other get taxed at a higher rate than families where two working partners earn the same total income split evenly between two paycheques. In fact, a family with just a single earner making $70,000 a year pays 30 per cent more in taxes every year than a family with two partners making $35,000 a year. A single-earner family taking in $120,000 a year pays the same income tax as a dualearning couple making $141,000 between them. The federal Conservative government has at least suggested it wants to finally level that playing field — nearly six decades after a royal commission recommended that the income tax system be changed to recognize total family household income, rather than focusing on each individual’s income. Given that Canada’s income tax system aims to treat people in similar circumstances as equally as possible, it is certainly time to let couples split their income so they do not face a penalty in higher tax rates than those faced by couples bringing home the same amount of total pay. While couples with just a single earner enjoy some advantages, a dual-earning couple does not — namely the extra time the stay-at-home spouse is able to use to raise children and produce other unpaid, home-based benefits — that can be accounted for using other means. Specifically, cutting out the transferability of the unused portion of the basic personal tax exemption for couples splitting income — requiring couples splitting their income to each earn money in order to use this credit — is one way to account for the difference in unpaid benefits that single-income families do typically enjoy more than dual-income couples. That is one mechanism; there may still be others the government might consider. But the

  7. Variable myopathic presentation in a single family with novel skeletal RYR1 mutation.

    Directory of Open Access Journals (Sweden)

    Ruben Attali

    Full Text Available We describe an autosomal recessive heterogeneous congenital myopathy in a large consanguineous family. The disease is characterized by variable severity, progressive course in 3 of 4 patients, myopathic face without ophthalmoplegia and proximal muscle weakness. Absence of cores was noted in all patients. Genome wide linkage analysis revealed a single locus on chromosome 19q13 with Zmax = 3.86 at θ = 0.0 and homozygosity of the polymorphic markers at this locus in patients. Direct sequencing of the main candidate gene within the candidate region, RYR1, was performed. A novel homozygous A to G nucleotide substitution (p.Y3016C within exon 60 of the RYR1 gene was found in patients. ARMS PCR was used to screen for the mutation in all available family members and in an additional 150 healthy individuals. This procedure confirmed sequence analysis and did not reveal the A to G mutation (p.Y3016C in 300 chromosomes from healthy individuals. Functional analysis on EBV immortalized cell lines showed no effect of the mutation on RyR1 pharmacological activation or the content of intracellular Ca(2+ stores. Western blot analysis demonstrated a significant reduction of the RyR1 protein in the patient's muscle concomitant with a reduction of the DHPRα1.1 protein. This novel mutation resulting in RyR1 protein decrease causes heterogeneous clinical presentation, including slow progression course and absence of centrally localized cores on muscle biopsy. We suggest that RYR1 related myopathy should be considered in a wide variety of clinical and pathological presentation in childhood myopathies.

  8. Microevolution of Helicobacter pylori during prolonged infection of single hosts and within families.

    2010-07-01

    Full Text Available Our understanding of basic evolutionary processes in bacteria is still very limited. For example, multiple recent dating estimates are based on a universal inter-species molecular clock rate, but that rate was calibrated using estimates of geological dates that are no longer accepted. We therefore estimated the short-term rates of mutation and recombination in Helicobacter pylori by sequencing an average of 39,300 bp in 78 gene fragments from 97 isolates. These isolates included 34 pairs of sequential samples, which were sampled at intervals of 0.25 to 10.2 years. They also included single isolates from 29 individuals (average age: 45 years from 10 families. The accumulation of sequence diversity increased with time of separation in a clock-like manner in the sequential isolates. We used Approximate Bayesian Computation to estimate the rates of mutation, recombination, mean length of recombination tracts, and average diversity in those tracts. The estimates indicate that the short-term mutation rate is 1.4 x 10(-6 (serial isolates to 4.5 x 10(-6 (family isolates per nucleotide per year and that three times as many substitutions are introduced by recombination as by mutation. The long-term mutation rate over millennia is 5-17-fold lower, partly due to the removal of non-synonymous mutations due to purifying selection. Comparisons with the recent literature show that short-term mutation rates vary dramatically in different bacterial species and can span a range of several orders of magnitude.

    Due to the Accreditation Council for Graduate Medical Education (ACGME)/American Osteopathic Association (AOA) single-accreditation model, the specialty of family medicine may see as many as 150 programs and 500 trainees in AOA-accredited programs seek ACGME accreditation. This analysis serves to better understand the composition of physicians completing family medicine residency training and their subsequent certification by the American Board of Family Medicine. We identified residents who completed an ACGME-accredited or dual-accredited family medicine residency program between 2006 and 2016 and cross-tabulated the data by graduation year and by educational background (US Medical Graduate-MD [USMG-MD], USMG-DO, or International Medical Graduate-MD [IMG-MD]) to examine the cohort composition trend over time. The number and proportion of osteopaths completing family medicine residency training continues to rise concurrent with a decline in the number and proportion of IMGs. Take Rates for USMG-MDs and USMG-IMGs seem stable; however, the Take Rate for the USMG-DOs has generally been rising since 2011. There is a clear change in the composition of graduating trainees entering the family medicine workforce. As the transition to a single accreditation system for graduate medical education progresses, further shifts in the composition of this workforce should be expected. © Copyright 2017 by the American Board of Family Medicine.

    It is currently unknown how the intensive and often prolonged treatment of childhood cancer impacts on the lives of single parents. Our aims were to determine whether single parents differ from parents from two-parent families in terms of caregiver demand (the time and effort involved in caregiving), and health-related quality of life (HRQL). Forty single parents and 275 parents from two-parent families were recruited between November 2004 and February 2007 from five pediatric oncology centers in Canada. Parents were asked to complete a questionnaire booklet composed of items and scales to measure caregiver demand and HRQL (SF-36). The booklet also measured the following constructs: background and context factors, child factors, caregiving strain, intrapsychic factors, and coping factors. Single parents did not differ from parents from two-parent families in caregiving demand and physical and psychosocial HRQL. Compared with Canadian population norms for the SF-36, both groups reported clinically important differences (i.e., worse health) in psychosocial HRQL (effect size ≥ -2.00), while scores for physical HRQL were within one standard deviation of population norms. Our findings suggest that the impact of caregiving on single parents, in terms of caregiving demand and HRQL is similar to that of parents from two-parent families.

    A growing body of literature examines urban water sustainability with increasing evidence that locally-based physical and social spatial interactions contribute to water use. These studies however are based on single-city analysis and often fail to consider whether these interactions occur more generally. We examine a multi-city comparison using a common set of spatially-explicit water, socioeconomic, and biophysical data. We investigate the relative importance of variables for explaining the variations of single family residential (SFR) water uses at Census Block Group (CBG) and Census Tract (CT) scales in four representative western US cities - Austin, Phoenix, Portland, and Salt Lake City, - which cover a wide range of climate and development density. We used both ordinary least squares regression and spatial error regression models to identify the influence of spatial dependence on water use patterns. Our results show that older downtown areas show lower water use than newer suburban areas in all four cities. Tax assessed value and building age are the main determinants of SFR water use across the four cities regardless of the scale. Impervious surface area becomes an important variable for summer water use in all cities, and it is important in all seasons for arid environments such as Phoenix. CT level analysis shows better model predictability than CBG analysis. In all cities, seasons, and spatial scales, spatial error regression models better explain the variations of SFR water use. Such a spatially-varying relationship of urban water consumption provides additional evidence for the need to integrate urban land use planning and municipal water planning.

  13. The building process of single-family houses and the embeddedness (or disembeddedness) of energy

    People building their own houses have, at least theoretically, substantial autonomy when choosing, for example, a heating system and windows. In this article, focus is on the process of building new single-family houses and how energy efficiency and energy-efficient technology are incorporated into the building process. The conclusions emphasize energy as only one factor in housing purchase decisions. It is a big challenge to make low-energy building important to consumers. Consumer preferences for new products are unlikely to fully develop unless individuals have the opportunity to interact with them. It is difficult for consumers to know what to ask for if they lack experience of energy-efficient technologies. In the studied cases, the building codes and established standards became extremely decisive for how energy issues were included in the process. There is a need to change the design of incentives so as to make the least energy-efficient choice the most expensive. The most energy-efficient solution should be standard, and if the buyer wants to depart from that standard and build using less energy-efficient construction, then that should cost more. -- Highlights: •Actors do not see energy efficiency as a critical problem. •Factors other than costs and price were important in the decision making. •Energy issues just one factor in housing purchase decisions. •The consumers don′t know what to ask for. •Building norms should require the most energy efficient solution

    Full Text Available Abstract Background Hypertrophic cardiomyopathy (HCM is an extremely heterogeneous disease. An under recognized and very often missed subgroup within this broad spectrum concerns patients with left ventricular (LV apical aneurysms in the absence of coronary artery disease. Case presentation We describe a case of HCM with midventricular obstruction and apical aneurysm formation in 3 patients coming from a single family. This HCM pattern was detected by 2D-echocardiography and confirmed by cardiac magnetic resonance imaging. A cardioverter defibrillator was implanted in one of the patients because of non-sustained ventricular tachycardia detected in 24-h Holter monitoring and an abrupt drop in systolic blood pressure during maximal exercise test. The defibrillator activated 8 months after implantation by suppression of a ventricular tachycardia providing anti-tachycardia pacing. The patient died due to refractory heart failure 2 years after initial evaluation. The rest of the patients are stable after a 2.5-y follow-up period. Conclusion The detection of apical aneurysm by echocardiography in HCM patients may be complicated. Ventricular tachycardia arising from the scarred aneurysm wall may often occur predisposing to sudden death.

    An instrumented single family residence in Greenville, South Carolina, has approximately 1086 square feet on conditioned space. Solar energy is used for space heating the home and preheating domestic and water (DHW). Solar energy enters the attic through a 416 square foot aperture which is double glazed with corrugated, translucent, fiberglass reinforced, acrylic panels. Warm air accumulates in the peak of the attic roof and circulates through the conditioned space or through storage by an air handler. Solar energy is stored in an 870 cubic foot storage bin containing 85,460 pounds of crushed rock located under the house. cold water is preheated in the attic by thermosiphoning water from the 80 gallon preheat tank through a manifold system of copper tubes. These tubes are attached to black sheet metal plates. Preheated city water is stored in the preheat tank and supplied, on demand, to a conventional 80 gallon DHW tank. When solar energy is insufficient to satisfy the space heating load, a water to air heat exchanger in the hot air supply duct provides auxiliary energy for space heating. A gas fired water heater provides auxiliary energy for the water to air heat exchanger and the DHW.

    In the near future, fuel cell-based residential micro-CHP systems will compete with traditional methods of energy supply. A micro-CHP system may be considered viable if its incremental capital cost compared to its competitors equals to cumulated savings during a given period of time. A simplified model is developed in this study to estimate the operation of a residential solid oxide fuel cell (SOFC) system. A comparative assessment of the SOFC system vis-à-vis heating systems based on gas, oil and electricity is conducted using the simplified model for a single-family house located in Ottawa and Vancouver. The energy consumption of the house is estimated using the HOT2000 building simulation program. A financial analysis is carried out to evaluate the sensitivity of the maximum allowable capital cost with respect to system sizing, acceptable payback period, energy price and the electricity buyback strategy of an energy utility. Based on the financial analysis, small (1-2 kW e) SOFC systems seem to be feasible in the considered case. The present study shows also that an SOFC system is especially an alternative to heating systems based on oil and electrical furnaces.

    2016-02-17

    Solar water heating systems are not new, but they have not become prevalent in most of the U.S. Most of the country is cold enough that indirect solar thermal systems are required for freeze protection, and average installed cost of these systems is $9,000 to $10,000 for typical systems on single-family homes. These costs can vary significantly in different markets and with different contractors, and federal and regional incentives can reduce these up-front costs by 50% or more. In western Massachusetts, an affordable housing developer built a community of 20 homes with a goal of approaching zero net energy consumption. In addition to excellent thermal envelopes and PV systems, the developer installed a solar domestic water heating system (SDHW) on each home. The Consortium for Advanced Residential Buildings (CARB), a research consortium funded by the U.S. Department of Energy Building America program, commissioned some of the systems, and CARB was able to monitor detailed performance of one system for 28 months.

    This exploratory, observational study was designed to reveal descriptive information regarding therapists' actual practices with preschool- and school-aged children in a single session of family therapy and to investigate change mechanisms in family play therapy that have been proposed to make this approach effective. A purposive sample of 30 families receiving family therapy was recruited and video-taped during a family session where at least one child between the ages of 4 and 12 was present. Following the session, the therapist and parent(s) completed questionnaires while one of the children (aged 4-12) was interviewed. Session recordings were coded, minute-by-minute, for participant talk time, visual aids or props used, and therapy technique type (e.g., play-based/activity vs. talk-only techniques). Hierarchical regression and canonical correlational analyses revealed evidence supporting the theory that play-based techniques promote young children's participation, enhance the quality of the child-therapist relationship, and build positive emotional experiences in family therapy. © 2013 American Association for Marriage and Family Therapy.

    Full Text Available Adolescence is a phase of emotionl turmoil and stress. If not balanced with religious practice, it may cause adolescents to fall into moral and social problems such as breach of school discipline, delinquency, drug addiction and sexual permissiveness. Religiosity is one way for adolescents to deal with challenges in life thereby avoiding immoral activities. This is because religiosity may help to balance adolescent emotional, cognitive and social developments.The purpose of this study is to identify the behaviour and level of religiosity among 30 adolescents from single parents families who settle in government-subsidised area of residence, namely known as the Federal Land Development Authority (FELDA. The area is located in the state of Pahang, situated on the eastern part of Malaysia. These adolescents have been selected as research respondents. This research was conducted as a survey using questionnaire as the research instrument. It was constructed based on the guidelines of Islamic Practice Instrument (IPI (Fariza, 2012 and has already been verified in terms of its validity and reliability. The data analysis has adopted the method of descriptive statistics explained in table form. The research results have found that religiosity or religious behaviour that the adolescents most frequently abide by are staying away from gambling, having good thoughts and expectations of Allah, feeling awed and fear of Allah’s power (taqwa, staying away from fornication (zina and supplication (doa to Allah facing the direction of Qibla. The level of religiosity is medium for most adolescents. This factor explains why not many respondents are involved in moral and disciplinary problems at school. This research finds that generally, religiosity protects adolescents from being involved in immoral activities and other vices.

    This study examined the frequency of personality, language, and social-behavioral characteristics believed to comprise the broad autism phenotype (BAP), across families differing in genetic liability to autism. We hypothesized that within this unique sample comprised of multiple-incidence autism families (MIAF), single-incidence autism families (SIAF), and control Down syndrome families (DWNS), a graded expression would be observed for the principal characteristics conferring genetic susceptibility to autism, in which such features would express most profoundly among parents from MIAFs, less strongly among SIAFs, and least of all among comparison parents from DWNS families, who should display population base rates. Analyses detected linear expression of traits in line with hypotheses, and further suggested differential intrafamilial expression across family types. In the vast majority of MIAFs both parents displayed BAP characteristics, whereas within SIAFs, it was equally likely that one, both, or neither parent show BAP features. The significance of these findings is discussed in relation to etiologic mechanisms in autism and relevance to molecular genetic studies. (c) 2007 Wiley-Liss, Inc.

    Single phase rare earth manganites have attracted scientific interest due to their interesting magnetic, electrical and structural properties. Bulk GdMnO 3 has metamagnetic features with a transition from antiferromagnetic to weak-ferromagnetic state upon cooling. Recently we have found promising magnetic behaviour when GdMnO 3 is doped with strontium. Magnetic behaviour of doped rare earth manganites in the form of Gd 1-x SrMnO 3 has attracted scientific interest due to their promising technological applications in data storage, as catalysts, as electrode materials and sensors. Irreversibility and sharp anomalies has been observed in the magnetization studies of polycrystalline Gd 0.99 Sr 0.01 MnO 3 perovskite synthesized by wet solid state reaction method. X-ray diffraction pattern of the system confirms the single phase orthorhombically distorted perovskite structure. The Field Cooled (FC) and Zero Field Cooled (ZFC) magnetization obtained as a function of temperature with external magnetic field 25Oe, 50Oe, and 200Oe showed thermal irreversibility along with a cusp below the ordering temperature indicating the appearance of spin glass state. The origin of this spin glass state is attributed to spin frustrations, due to the rare earth ions forming a deformed Kagome lattice. Under a magnetic field of 25Oe, the splitting between FC and ZFC magnetization is observed at 70K with a cusp in M ZFC at 45K and when the field is increased to 50Oe and 200Oe, the splitting becomes narrower and shows a shift in the irreversible temperature (T irr ) to lower temperatures 59K and 50K respectively. The spins are frozen in random directions due to a lack of long range magnetic interactions, when the system is cooled through its freezing temperature T f to T f . Room temperature variation of magnetization with applied field indicates the existence of ferromagnetic clusters of glass over antiferromagnetic background. Thermal irreversibility between FC and ZFC below T irr with a

    The synthesis and magnetic properties of three isostructural hexadecametallic manganese clusters [Mn(16)O(16)(OMe)(6)(O(2)CCH(2)Ph)(16)(MeOH)(6)] (1), [Mn(16)O(16)(OMe)(6)(O(2)CCH(2)Cl)(16)(MeOH)(6)] (2), and [Mn(16)O(16)(OMe)(6)(O(2)CCH(2)Br)(16)(MeOH)(6)] (3) are reported. The complexes were prepared by a reductive aggregation reaction involving phenylacetic acid, chloroacetic acid or bromoacetic acid, and NBu(n)()(4)MnO(4) in MeOH. Complex 1 crystallizes in the monoclinic space group C2/c and consists of 6 Mn(IV) and 10 Mn(III) ions held together by 14 mu(3)-O(2)(-), 2 mu-O(2)(-), 4 mu-MeO(-), and 2 mu-O(2)CCH(2)Ph(-) groups. The remaining 14 mu-O(2)CCH(2)Ph(-) ligands, 2 mu-MeO(-) groups, and 6 terminal MeOH molecules constitute the peripheral ligation in the complex. Variable-temperature, solid-state dc magnetic susceptibility measurements on 1-3 in the temperature range 5.0-300 K reveal that all three complexes are dominated by intramolecular antiferromagnetic exchange interactions. Low-lying excited states preclude an exact determination of the spin ground state for 1-3 by magnetization measurements. Alternating current susceptibility measurements at zero dc field in the temperature range 1.8-10 K and a 3.5 G ac field oscillating at frequencies in the 5-1488 Hz range display, at temperatures below 3 K, a nonzero, frequency-dependent chi(M)"signal for complexes 1-3, with the peak maxima lying at temperatures less than 1.8 K. Single-crystal magnetization versus dc field scans down to 0.04 K for complex 1 show hysteresis behavior at SMM family. No clear steps characteristic of quantum tunneling of magnetization (QTM) were observed in the hysteresis loops.

  7. Retrofitting Domestic Hot Water Heaters for Solar Water Heating Systems in Single-Family Houses in a Cold Climate: A Theoretical Analysis

    Directory of Open Access Journals (Sweden)

    2012-10-01

    Full Text Available One of the biggest obstacles to economic profitability of solar water heating systems is the investment cost. Retrofitting existing domestic hot water heaters when a new solar hot water system is installed can reduce both the installation and material costs. In this study, retrofitting existing water heaters for solar water heating systems in Swedish single-family houses was theoretically investigated using the TRNSYS software. Four simulation models using forced circulation flow with different system configurations and control strategies were simulated and analysed in the study. A comparison with a standard solar thermal system was also presented based on the annual solar fraction. The simulation results indicate that the retrofitting configuration achieving the highest annual performance consists of a system where the existing tank is used as storage for the solar heat and a smaller tank with a heater is added in series to make sure that the required outlet temperature can be met. An external heat exchanger is used between the collector circuit and the existing tank. For this retrofitted system an annual solar fraction of 50.5% was achieved. A conventional solar thermal system using a standard solar tank achieves a comparable performance for the same total storage volume, collector area and reference conditions.

    This study investigated the resilience of single-family housing values in walkable versus unwalkable neighborhoods during the economic downturn from 2008 to 2012 in Dallas, Texas. Using propensity score matching and difference in differences methods, this study established a natural experimental design to compare before-and-after value changes of single-family (SF) homes in walkable neighborhoods with unwalkable neighborhoods during the Great Recession. Two thousand seven hundred ninety-nine SF homes within 18 Tax Increment Financing (TIF) districts were categorized into walkable (Walk Score ≥50) and unwalkable (economic benefit. Increased awareness of the sustained value of walkable communities can be used by lenders who finance and by policy makers who regulate placemaking. Results from this study can be integrated with research that demonstrates health-care cost savings of walkable environments to create an even more comprehensive set of evidence-based interventions to increase their supply.

    2012-01-01

    The stocks and flows of six major structural wood products (SWPs)-lumber, plywood, oriented strand board [OSB], glue laminated timber, I-joists, and laminated veneer lumber (LVL)-in US single family homes were modeled from 1950 to 2010. The consumption of these products in US single family homes...... and their emissions as construction and demolition wastes were estimated. The net consumption of SWPs decreased from 119 kg/m2 constructed in 1986 to 82 kg/m2 in 2010. Softwood lumber was consistently the predominant SWP, but its usage intensity decreased from 95 kg/m2 in 1986 to 52 kg/ m2 in 2010. Since the 1980s......, modern SWPs, such as I-joists, LVL, and OSB, have replaced lumber and plywood products. The needs of the US single family housing industry have been met by a smaller mass of SWPs per unit area constructed. The mass of SWP present in construction wastes was influenced strongly by building cycles...

    Viruses infecting archaea show a variety of virion morphotypes, and they are currently classified into more than ten viral families or corresponding groups. A pleomorphic virus morphotype is very common among haloarchaeal viruses, and to date, several such viruses have been isolated. Here, we propose the classification of eight such viruses and formation of a new family, Pleolipoviridae (from the Greek pleo for more or many and lipos for lipid), containing three genera, Alpha-, Beta-, and Gammapleolipovirus. The proposal is currently under review by the International Committee on Taxonomy of Viruses (ICTV). The members of the proposed family Pleolipoviridae infect halophilic archaea and are nonlytic. They share structural and genomic features and differ from any other classified virus. The virion of pleolipoviruses is composed of a pleomorphic membrane vesicle enclosing the genome. All pleolipoviruses have two major structural protein species, internal membrane and spike proteins. Although the genomes of the pleolipoviruses are single- or double-stranded, linear or circular DNA molecules, they share the same genome organization and gene synteny and show significant similarity at the amino acid level. The canonical features common to all members of the proposed family Pleolipoviridae show that they are closely related and thus form a new viral family.

    Family members and friends of patients with advanced chronic illness are increasingly called on to assist with ever more complex medical care and treatment decisions arising late in the course of illness. Our goal was to learn about the experiences of family members and friends of patients with advanced kidney disease. As part of a study intended to identify opportunities to enhance advance care planning, we conducted semistructured interviews at the Veterans Affairs Puget Sound Health Care System with 17 family members and friends of patients with advanced kidney disease. Interviews were conducted between April of 2014 and May of 2016 and were audiotaped, transcribed, and analyzed inductively using grounded theory to identify emergent themes. The following three themes emerged from interviews with patients' family members and friends: ( 1 ) their roles in care and planning were fluid over the course of the patient's illness, shaped by the patients' changing needs and their readiness to involve those close to them; ( 2 ) their involvement in patients' care was strongly shaped by health care system needs. Family and friends described filling gaps left by the health care system and how their involvement in care and decision-making was at times constrained and at other times expected by providers, depending on system needs; and ( 3 ) they described multiple sources of tension and conflict in their interactions with patients and the health care system, including instances of being pitted against the patient.

    . These benefits can be maximized if district heating temperatures are lowered as much as possible. In this paper we report on a project where 18 Danish single-family houses from the 1980s were supplied by ultra-low temperature district heating with a supply temperature as low as 45 degrees C for the main part...... of the year. The houses were heated by the existing hydraulic radiator systems, while domestic hot water was prepared by use of district heating and electric boosting. This paper evaluated the heating system temperatures that were necessary in order to maintain thermal comfort in four of the houses. First...... the four houses were modelled in the building simulation tool IDA ICE. The simulation models included the actual radiator sizes and the models were used to simulate the expected thermal comfort in the houses and resulting district heating return temperatures.

    Neuronal migration disorders can now be recognised by MRI. This paper reports two families in which the mothers had subcortical laminar heterotopia and four of their children had either similar heterotopia (two girls) or severe pachygyria or lissencephaly (two boys). Laminar heterotopia was more evident on MRI T2 weighted images. The patients had mild to severe epilepsy and mental retardation depending on the extent of cortical abnormalities. In these families, subcortical laminar heterotopia, pachygyria, and lissencephaly seem to share the same X linked or autosomal dominant gene. No chromosomal abnormalities, especially of chromosome 17, could be identified. For appropriate genetic counselling of the family of a child with lissencephaly or subcortical laminar heterotopia, MRI should be performed in parents or siblings with mental retardation or epilepsy.

    2011-11-01

    Research into the process of becoming mother or father shows very conclusively that this important life transition is accompanied by both a decrease in marital quality and a more traditional division of labour. In this paper these changes are analyzed with special emphasis on the relationships between them and exploring the role played in this process by the mother's work status. Results showed a significant link between the development of marital quality and violated expectations regarding father involvement on childrearing. Dual-earner families were characterized by a specific pattern of changes, with greater stability than single-earner families in marital and parental roles during transition to parenthood and a significant role played by spouse support as a partner, but not as a parent.

    Considerable progress has been made in recent years in developing effective treatments for child and adolescent anorexia nervosa, with a general consensus in the field that eating disorders focussed family therapy (often referred to as Maudsley Family Therapy or Family Based Treatment) currently offers the most promising outcomes. Nevertheless, a significant number do not respond well and additional treatment developments are needed to improve outcomes. Multifamily therapy is a promising treatment that has attracted considerable interest and we report the results of the first randomised controlled trial of multifamily therapy for adolescent anorexia nervosa. The study was a pragmatic multicentre randomised controlled superiority trial comparing two outpatient eating disorder focussed family interventions - multifamily therapy (MFT-AN) and single family therapy (FT-AN). A total of 169 adolescents with a DSM-IV diagnosis of anorexia nervosa or eating disorder not otherwise specified (restricting type) were randomised to the two treatments using computer generated blocks of random sizes to ensure balanced numbers in the trial arms. Independent assessors, blind to the allocation, completed evaluations at baseline, 3 months, 12 months (end of treatment) and 18 months. Both treatment groups showed clinically significant improvements with just under 60% achieving a good or intermediate outcome (on the Morgan-Russell scales) at the end of treatment in the FT-AN group and more than 75% in the MFT-AN group - a statistically significant benefit in favour of the multifamily intervention (OR = 2.55 95%; CI 1.17, 5.52; p = 0.019). At follow-up (18 months post baseline) there was relatively little change compared to end of treatment although the difference in primary outcome between the treatments was no longer statistically significant. Clinically significant gains in weight were accompanied by improvements in mood and eating disorder psychopathology. Approximately

    Primary ciliary dyskinesia (PCD) is a rare autosomal recessive disorder characterised by abnormal ciliary motion and impaired mucociliary clearance, leading to recurrent respiratory infections, sinusitis, otitis media and male infertility. Some patients also have laterality defects. We recently reported the identification of three disease-causing PCD genes in the Irish Traveller population; RSPH4A, DYX1C1 and CCNO. We have since assessed an additional Irish Traveller family with a complex phenotype involving PCD who did not have any of the previously identified PCD mutations.

  16. Why preeclampsia still exists?

    2013-08-01

    Preeclampsia (PE) is a deadly gestational disease affecting up to 10% of women and specific of the human species. Preeclampsia is clearly multifactorial, but the existence of a genetic basis for this disease is now clearly established by the existence of familial cases, epidemiological studies and known predisposing gene polymorphisms. PE is very common despite the fact that Darwinian pressure should have rapidly eliminated or strongly minimized the frequency of predisposing alleles. Consecutive pregnancies with the same partner decrease the risk and severity of PE. Here, we show that, due to this peculiar feature, preeclampsia predisposing-alleles can be differentially maintained according to the familial structure. Thus, we suggest that an optimal frequency of PE-predisposing alleles in human populations can be achieved as a result of a trade-off between benefits of exogamy, importance for maintaining genetic diversity and increase of the fitness owing to a stable paternal investment.

    2013-06-01

    Full Text Available Citizens protest development when they consider it undesirable. One type of development commonly perceived as undesirable by single-family home owners is proximate multifamily housing, often considered a cause of property devaluation. This study assesses multifamily housing, by typology, and its monetary association with proximate single-family housing prices. The research design is a cross-sectional study using multivariate regression. The unit of analysis is the detached single-family dwelling. The study population is a sample taken from all arms-length owner-occupied, primary residence, detached single-family property transactions recorded in Tallahassee-Leon County, Florida, USA, during 2008. The key findings show no statistically significant negative associations between multifamily housing and single-family property selling prices in the sample; in fact, the two were positively correlated. These findings address single-family homeowner concerns about proximate multifamily housing and should bolster the political feasibility of Smart Growth policy, which recommends denser urban infill.

    Based on a sample of 432 poor Chinese single-mother families (mean age of adolescents = 13.7 years; 51.2% girls; mean age of mothers = 43.5 years) in Hong Kong, the interaction effect of mother-reported and adolescent-reported maternal control on filial piety of Chinese adolescents was examined. Results of polynomial multiple regression analyses showed that the interaction between mother-reported and adolescent-reported maternal control predicted perceived filial piety in adolescents. At high levels of mother-reported maternal control, high adolescent-perceived parental control was associated with higher filial piety. At low levels of mother-reported maternal control, filial piety increased initially and then decreased when adolescents reported higher levels of maternal control. Using multiple group analyses, these associations were found to be stable across gender and age. The present findings provide insights on how congruencies and discrepancies between mother-reported and adolescent-reported maternal control predict filial piety of Chinese adolescents growing up in poor single-mother families.

    The family Chlamydiaceae (order Chlamydiales, phylum Chlamydiae) comprises important, obligate intracellular bacterial pathogens of humans and animals. Subdivision of the family into the two genera Chlamydia and Chlamydophila has been discussed controversially during the past decade. Here, we have revisited the current classification in the light of recent genomic data and in the context of the unique biological properties of these microorganisms. We conclude that neither generally used 16S rRNA sequence identity cut-off values nor parameters based on genomic similarity consistently separate the two genera. Notably, no easily recognizable phenotype such as host preference or tissue tropism is available that would support a subdivision. In addition, the genus Chlamydophila is currently not well accepted and not used by a majority of research groups in the field. Therefore, we propose the classification of all 11 currently recognized Chlamydiaceae species in a single genus, the genus Chlamydia. Finally, we provide emended descriptions of the family Chlamydiaceae, the genus Chlamydia, as well as the species Chlamydia abortus, Chlamydia caviae and Chlamydia felis.

    Neonatal intensive care units have historically been constructed as open units or multiple-bed bays, but since the 1990s, the trend has been toward single family room (SFR) units. The SFR design has been found to promote family-centered care and to improve patient outcomes and safety. The impact of the SFR design NICU on staff, however, has been mixed. The purposes of this study were to compare staff nurse perceptions of their work environments in an open-pod versus an SFR NICU and to compare staff nurse perceptions of the impact of 2 NICU designs on the care they provide for patients/families. A prospective cohort study was conducted. Questionnaires were completed at 6 months premove and again at 3, 9, and 15 months postmove. A series of 1-way analyses of variance were conducted to compare each group in each of the 8 domains. Open-ended questions were evaluated using thematic analysis. The SFR design is favorable in relation to environmental quality and control of primary workspace, privacy and interruption, unit features supporting individual work, and unit features supporting teamwork; the open-pod design is preferable in relation to walking. Incorporating design features that decrease staff isolation and walking and ensuring both patient and staff safety and security are important considerations. Further study is needed on unit design at a microlevel including headwall design and human milk mixing areas, as well as on workflow processes.

  1. Replacing critical radiators to increase the potential to use low-temperature district heating – A case study of 4 Danish single-family houses from the 1930s

    Low-temperature district heating is a promising technology for providing homes with energy-efficient heating in the future. However, it is of great importance to maintain thermal comfort in existing buildings when district heating temperatures are lowered. This case study evaluated the actual radiator sizes and heating demands in 4 existing Danish single-family houses from the 1930s. A year-long dynamic simulation was performed for each of the houses to evaluate the potential to lower the heating system temperatures. The results indicate that there is a large potential to use low-temperature district heating in existing single-family houses. In order to obtain the full potential of low-temperature district heating, critical radiators must be replaced. Based on a novel method, a total of nine radiators were identified to be critical to ensure thermal comfort and low return temperatures in two of the case-houses. If these radiators were replaced it would be possible to lower the average heating system temperatures to 50 °C/27 °C in all four houses. - Highlights: • Comparison of dynamically calculated heat demands and radiator sizes. • Method for identification and evaluation of critical radiators was tested. • Existing houses can be heated with low-temperature heating for most of the year. • Replacing critical radiators helps ensure comfort and low return temperatures.

    Full Text Available We assessed differences in the rates of smoke-free homes among single-parent households with regard to parental race/ethnicity and smoking status. We identified two cohorts representative of the U.S. single-parent households with underage children (children under the age of 18 based on the Tobacco Use Supplement to the Current Population Survey: 2010–11 (n=6474 and 2014–15 (n=6114. The interviews were conducted by phone and in-person. Statistical analysis was performed in 2017. The overall rate of smoke-free homes was 82% in 2010–11 and 86% in 2014–15. The rate of a smoke-free home was highest for Non-Hispanic (NH Asian (94% and Hispanic (92% parents and lowest for NH Multiracial (77% in 2010–11 and 82% in 2014–15 in both survey periods. However, 2014–15 model-based comparisons relative to NH Whites indicated only one significant difference: the rate was lower for NH Blacks (OR=0.46, 99% CI=0.32:0.66. The smoke-free homes were least prevalent among daily smokers, followed by occasional smokers, followed by former smokers, and most prevalent among never smokers in each survey period. The 2010–11 and 2014–15 rates were 45% and 54% for daily, 64% and 72% for occasional, 89% and 91% for former, and 93% and 94% for never smokers. The gap in the rates of smoke-free homes for diverse parental racial/ethnic groups observed in 2010–11 decreased by 2014–15. While smoke-free homes became more prevalent in 2014–15, the rates remain drastically different among families with different parental smoking behaviors. Exposure to secondhand smoke at home remains common among single-parent households where the parent smokes.

    2007-02-01

    Much of the documented work on families headed by single mothers is based on empirical evidence from North America and a few Anglo-Saxon countries. Many researchers consider single-mother families to be at a disadvantage because of nonsupportive family policies. This paper uses data from a social context that differed hugely in this respect-the German Democratic Republic (GDR). The GDR provided extensive state support to single-mother families and, thus, was vastly different from other countries. Based on a literature review and using Hill's family stress theory, this paper is based on the hypothesis that adolescents living in mother-headed single-parent families and those living with their biological parents would have near-similar social outcomes (display of psychosomatic symptoms, perception of stress, display of delinquent behaviour, life satisfaction, academic self-efficacy, and academic grades) and family-related outcomes (relationship with parents and perception of family environment). Further, it was hypothesized that adolescents from stepfather families would display more negative social and family-related outcomes when compared with respondents from the other two family types. The sample comprised 1302 adolescents (M  =  13.82 years, SD  =  1.88) who were recruited from the city of Leipzig in the year immediately following German unification, 1991. Respondents reported on measures of psychosomatic symptoms, stress, delinquency, life satisfaction, academic achievement, and family-related variables. ANCOVAs, with a control for income adjusted for household size, indicated adolescents from single-mother families to have very similar experiences to respondents living with their biological parents on all measures except for their assessment of family environment. Adolescents living in stepfather families reported the least favourable experiences. Results are indicative of a social context in Germany that, despite unification and the early hardships for

    Full Text Available The article is devoted to one of the problems of personality development of today’s teenagers pertaining to their self-attitude and psychological defence. It presents the results of a comparative analysis of self-attitude development specifics and manifestation of defence mechanisms in teenagers from full and single-parent families as well as special traits of interconnection of self-attitude main components and some types of psychological defence that are typical for them. Better well-being and greater disposition to approve of themselves has been revealed among those raised in full families as against a tendency to self-disparagement, besides the more intensive use of psychological defence, of their peers from single-parent families. It has been established that family structure defined by the principle “full” - “single-parent” is an important factor of self-attitude development and manifestation of psychological defence in teenagers.

    This paper reports on the experiences and views of children and young people of single-parent families, as findings from a European Union-funded research project undertaken in England, Greece and Cyprus. The objectives of the research project were to investigate how children and young people of single-parent families understand and experience their worlds as members of these families: whether and to what extent they experience poverty and social exclusion and how they cope with the challenges that this confronts them with. Methodology was replicated in each of the countries; however, this paper draws on the English experiences. Semistructured interviews (40) and focus groups (four) were undertaken with children of single parents. In addition, focus groups were undertaken with children of two-parent families (four), focus groups with single parents, focus groups with two-parent families (four) and individual interviews with key professionals. Detailed discussion guides were followed, with open-ended questions to allow participants to express their feelings and ideas in their own words. The research sample included children from single-parent and two-parent families, aged 6 years to 16 years, balanced in terms of age, gender and geographical location. Findings demonstrate the children's and young people's understanding of the impact of poverty and social exclusion on their family life and their everyday experiences. The positive benefits of being in a single-parent family are highlighted, with 'time poverty' raised as a significant issue. Children and young people are aware of their poverty and how it influences exclusion from friendships, play, leisure and community activities. Policy needs to take account of the systematic reality of children's experiences; alliances with adults that support meaningful involvement and participation by children and young people will make a significant contribution to this.

    and the calculated indoor temperatures and radiator return temperatures were compared to temperatures measured in the case house. The results showed that the detail of the simulation model has a large influence on the results obtained. The estimated return temperatures from the radiators varied by up to 16 degrees C...... depending on the assumptions made in the simulation model. The results indicated that a detailed building simulation model can provide a good estimate of the actual heating system operation, provided that actual radiators and realistic indoor temperatures are taken into account in the model.

    A radiation dose consequence analysis has been performed for a postulated scenario in which an exploratory gas or oil well-bore penetrates the repository and intercepts a brine reservoir in the Castile formation. The brine, corings and drilling mud are contained in a one acre holding pond on the surface. Upon the completion of drilling activities the dried holding pond area is reclaimed with a bulldozer to its original topographic conformation. The estimated radiation bone dose commitments to (1) a bulldozer operator, and (2) a member of a farm family 500 meters down wind are summarized for three penetration event times. The highest estimated 50 year bone dose commitment to an individual reclaiming the contaminated holding pond area was determined to be 590 mrem from the inhalation of CH-TRU wastes resuspended into the atmosphere at an event time of 100 years post-closure. A second dose model using a specific activity approach is developed in Appendix C for this same individual where an upper 50 year dose commitment of 450 mrem is calculated. Both of these derived estimates may be compared to the 5800 mrem to bone surfaces which may be expected from natural background radiation to an individual in the United States over a fifty year period

    Sheeppox, goatpox and peste des petits ruminants (PPR) are highly contagious ruminant diseases widely distributed in Africa, the Middle East and Asia. Capripoxvirus (CPV)-vectored recombinant PPR vaccines (rCPV-PPR vaccines), which have been developed and shown to protect against both Capripox (CP) and PPR, would be critical tools in the control of these important diseases. In most parts of the world, these disease distributions overlap each other leaving concerns about the potential impact that pre-existing immunity against either disease may have on the protective efficacy of these bivalent rCPV-PPR vaccines. Currently, this question has not been indisputably addressed. Therefore, we undertook this study, under experimental conditions designed for the context of mass vaccination campaigns of small ruminants, using the two CPV recombinants (Kenya sheep-1 (KS-1) strain-based constructs) developed previously in our laboratory. Pre-existing immunity was first induced by immunization either with an attenuated CPV vaccine strain (KS-1) or the attenuated PPRV vaccine strain (Nigeria 75/1) and animals were thereafter inoculated once subcutaneously with a mixture of CPV recombinants expressing either the hemagglutinin (H) or the fusion (F) protein gene of PPRV (10(3) TCID50/animal of each). Finally, these animals were challenged with a virulent CPV strain followed by a virulent PPRV strain 3 weeks later. Our study demonstrated full protection against CP for vaccinated animals with prior exposure to PPRV and a partial protection against PPR for vaccinated animals with prior exposure to CPV. The latter animals exhibited a mild clinical form of PPR and did not show any post-challenge anamnestic neutralizing antibody response against PPRV. The implications of these results are discussed herein and suggestions made for future research regarding the development of CPV-vectored vaccines. Copyright © 2014 Elsevier Ltd.

    Full Text Available Abstract Background The nuclear envelope that separates the contents of the nucleus from the cytoplasm provides a surface for chromatin attachment and organization of the cortical nucleoplasm. Proteins associated with it have been well characterized in many eukaryotes but not in plants. SUN (Sad1p/Unc-84 domain proteins reside in the inner nuclear membrane and function with other proteins to form a physical link between the nucleoskeleton and the cytoskeleton. These bridges transfer forces across the nuclear envelope and are increasingly recognized to play roles in nuclear positioning, nuclear migration, cell cycle-dependent breakdown and reformation of the nuclear envelope, telomere-led nuclear reorganization during meiosis, and karyogamy. Results We found and characterized a family of maize SUN-domain proteins, starting with a screen of maize genomic sequence data. We characterized five different maize ZmSUN genes (ZmSUN1-5, which fell into two classes (probably of ancient origin, as they are also found in other monocots, eudicots, and even mosses. The first (ZmSUN1, 2, here designated canonical C-terminal SUN-domain (CCSD, includes structural homologs of the animal and fungal SUN-domain protein genes. The second (ZmSUN3, 4, 5, here designated plant-prevalent mid-SUN 3 transmembrane (PM3, includes a novel but conserved structural variant SUN-domain protein gene class. Mircroarray-based expression analyses revealed an intriguing pollen-preferred expression for ZmSUN5 mRNA but low-level expression (50-200 parts per ten million in multiple tissues for all the others. Cloning and characterization of a full-length cDNA for a PM3-type maize gene, ZmSUN4, is described. Peptide antibodies to ZmSUN3, 4 were used in western-blot and cell-staining assays to show that they are expressed and show concentrated staining at the nuclear periphery. Conclusions The maize genome encodes and expresses at least five different SUN-domain proteins, of which the PM3

    Full Text Available Abstract Background Dengue virus type 1 (DENV-1 have been mostly circulating silently with dominant serotypes DENV-2 and DENV-3 in India. However recent times have marked an increase in DENV-1 circulation in yearly outbreaks. Many studies have not been carried out on this virus type, leaving a lacunae pertaining to the circulating genotypes, since its earliest report in India. In the present study, we sequenced CprM gene junction of 13 DENV-1 isolated from Delhi and Gwalior (North India between 2001–2007 and one 1956 Vellore isolate as reference. For comparison, we retrieved 11 other Indian and 70 global reference sequences from NCBI database, making sure that Indian and global isolates from all decades are available for comparative analysis. Results The region was found to be AT rich with no insertion or deletion. Majority of the nucleotide substitutions were silent, except 3 non-conservative amino acid changes (I → T, A → T and L → S at amino acid positions 59,114 and 155 respectively in the Indian DENV-1 sequences, sequenced in this study. Except two 1997–98 Delhi isolates, which group in genotype I; all other Indian isolates group in genotype III. All Indian genotype III DENV-1 exhibited diversity among them, giving rise to at least 4 distinct lineages (India 1–4 showing proximity to isolates from diverse geographic locations. Conclusion The extensive phylogenetic analysis revealed consistent existence of multiple lineages of DENV-1 genotype III during the last 5 decades in India.

    We assessed differences in the rates of smoke-free homes among single-parent households with regard to parental race/ethnicity and smoking status. We identified two cohorts representative of the U.S. single-parent households with underage children (children under the age of 18) based on the Tobacco Use Supplement to the Current Population Survey: 2010-11 ( n  = 6474) and 2014-15 ( n  = 6114). The interviews were conducted by phone and in-person. Statistical analysis was performed in 2017. The overall rate of smoke-free homes was 82% in 2010-11 and 86% in 2014-15. The rate of a smoke-free home was highest for Non-Hispanic (NH) Asian (94%) and Hispanic (92%) parents and lowest for NH Multiracial (77% in 2010-11 and 82% in 2014-15) in both survey periods. However, 2014-15 model-based comparisons relative to NH Whites indicated only one significant difference: the rate was lower for NH Blacks (OR = 0.46, 99% CI = 0.32:0.66). The smoke-free homes were least prevalent among daily smokers, followed by occasional smokers, followed by former smokers, and most prevalent among never smokers in each survey period. The 2010-11 and 2014-15 rates were 45% and 54% for daily, 64% and 72% for occasional, 89% and 91% for former, and 93% and 94% for never smokers. The gap in the rates of smoke-free homes for diverse parental racial/ethnic groups observed in 2010-11 decreased by 2014-15. While smoke-free homes became more prevalent in 2014-15, the rates remain drastically different among families with different parental smoking behaviors. Exposure to secondhand smoke at home remains common among single-parent households where the parent smokes.

  17. Retrofitted Solar Domestic Hot Water Systems for Swedish Single-Family Houses—Evaluation of a Prototype and Life-Cycle Cost Analysis

    2016-11-01

    Full Text Available According to recent technology road maps, system cost reductions and development of standardised plug-and-function systems are some of the most important goals for solar heating technology development. Retrofitting hot water boilers in single-family houses when installing solar collectors has the potential to significantly reduce both material and installation costs. Previous studies have investigated such retrofitting, using theoretical simulations and laboratory tests, but no actual installations were made and tested in practice. This article describes the installation, measured performance and cost effectiveness of a retrofitting solution that converts existing domestic hot water heaters to a solar domestic hot water system. The measured performance is characterised by the monthly and annual solar fractions. The cost effectiveness is evaluated by a life-cycle cost analysis, comparing the retrofitted system to a conventional solar domestic hot water system and the case without any solar heating system. Measurements showed that approximately 50% of the 5000 kWh/year of domestic hot water consumption was saved by the retrofitted system in south Sweden. Such savings are in agreement with previous estimations and are comparable to the energy savings when using a conventional solar domestic hot water system. The life-cycle cost analysis showed that, according to the assumptions and given climate, the return on investment of the retrofitted system is approximately 17 years, while a conventional system does not reach profitability during its lifetime of 25 years.

    Moving beyond simply documenting that political violence negatively impacts children, we tested a social-ecological hypothesis for relations between political violence and child outcomes. Participants were 700 mother-child (M = 12.1 years, SD = 1.8) dyads from 18 working-class, socially deprived areas in Belfast, Northern Ireland, including single- and two-parent families. Sectarian community violence was associated with elevated family conflict and children's reduced security about multiple aspects of their social environment (i.e., family, parent-child relations, and community), with links to child adjustment problems and reductions in prosocial behavior. By comparison, and consistent with expectations, links with negative family processes, child regulatory problems, and child outcomes were less consistent for nonsectarian community violence. Support was found for a social-ecological model for relations between political violence and child outcomes among both single- and two-parent families, with evidence that emotional security and adjustment problems were more negatively affected in single-parent families. The implications for understanding social ecologies of political violence and children's functioning are discussed.

    Sézary Syndrome (SS/L-CTCL) is a rare but aggressive variant of cutaneous T cell lymphoma (CTCL), characterized by erythroderma, lymphadenopathy, and the presence of a circulating memory CD4(+) T cell malignant clone with a skin homing behavior, lacking CD26 and CD49d and over-expressing CD60. The availability of a panel of monoclonal antibodies recognizing distinct TCR-Vβ families, allows to typify the clone by flow cytometry in about 70 % of cases. The TCR-Vβ repertoire of 533 individuals, comprising 308 patients affected by CTCL, 50 healthy donors, and subjects affected by various non-neoplastic dermatological affections was evaluated by flow cytometry. Statistical analyses were performed using the SPSS statistical software package for Microsoft Windows (SPSS, version 21, Chicago, IL). TCR-Vβ2 levels below 5.4 % or above 39.5 %, within total CD4(+) T cells, showed the best balance between sensitivity (98.1 %) and specificity (96 %) to identify the presence of a clone in the peripheral blood of patients affected by SS. Based on this observation, a "two-step" procedure in the detection of the malignant T cell clone in CTCLs is herein suggested. TCR-Vβ2 assessment in all cases (first step). In the case of TCR-Vβ2 levels above 39.5 %, the presence of a clonal expansion of this family is suggested, deserving further confirmation by means of T cell gene rearrangement evaluation. In patients having a TCR-Vβ2 reactivity below 5.4 % (second step), the entire TCR-Vβ repertoire should be evaluated to typify the expanded clone. In conclusion, the single TCR-Vβ2 expression check, instead of the entire repertoire assessment, represents an easy and cost-effective method for the recognition of CTCL aggressive leukemic variant.

    This study combines micro-level data on families with children from the Panel Study of Income Dynamics with neighborhood-level industrial hazard data from the Environmental Protection Agency and neighborhood-level U.S. census data to examine both the association between family structure and residential proximity to neighborhood pollution and the micro-level, residential mobility processes that contribute to differential pollution proximity across family types. Results indicate the existence of significant family structure differences in household proximity to industrial pollution in U.S. metropolitan areas between 1990 and 1999, with single-mother and single-father families experiencing neighborhood pollution levels that are on average 46% and 26% greater, respectively, than those experienced by two-parent families. Moreover, the pollution gap between single-mother and two-parent families persists with controls for household and neighborhood socioeconomic, sociodemographic, and race/ethnic characteristics. Examination of underlying migration patterns reveals that single-mother, single-father, and two-parent families are equally likely to move in response to pollution. However, mobile single-parent families move into neighborhoods with significantly higher pollution levels than do mobile two-parent families. Thus, family structure differences in pollution proximity are maintained more by these destination neighborhood differences than by family structure variations in the likelihood of moving out of polluted neighborhoods.

    Family history of cancer is a risk factor for gastric cancer. In this study, we investigated the prognoses of gastric cancer patients with family history of cancer. A total of 1805 gastric cancer patients who underwent curative gastrectomy from 2000 to 2008 were evaluated. The clinicopathologic parameters and prognoses of gastric cancer patients with a positive family history (PFH) of cancer were compared with those with a negative family history (NFH). Of 1805 patients, 382 (21.2%) patients had a positive family history of cancer. Positive family history of cancer correlated with younger age, more frequent alcohol and tobacco use, worse differentiation, smaller tumor size, and more frequent tumor location in the lower 1/3 of the stomach. The prognoses of patients with a positive family history of cancer were better than that of patients with a negative family history. Family history of cancer independently correlated with better prognosis after curative gastrectomy in gastric cancer patients.

    The majority (67%) of African American youth live in single-parent households, a shift in the family structure that has been linked to increased risk for both internalizing and externalizing problem behaviors. Although the majority of single mothers endorse the assistance of another adult or family member in child rearing, relatively little is known about who is engaged in this nonmarital coparenting role (i.e., grandmother, father/social father, aunt, and female family friend) and how it relates to coparenting quality, maternal parenting, and youth psychosocial outcomes (i.e., internalizing and externalizing problems). This question, which is critical to the advancement of family focused programming for youth in these families, is addressed in this study. The participants examined in the current study were 159 African American single-mother child dyads. Adolescents' maternal grandmothers constituted the largest proportion of coparents in the sample (37.2%), followed by the mothers' female family friends (22.5%), adolescents' maternal aunts (12.7%), and adolescents' fathers/social fathers (11%). Differences emerged among groups of coparents in support and conflict with the mother. Specifically, grandmothers, aunts, and female family friends provided significantly more instrumental support than fathers. Furthermore, grandmothers and fathers had more conflict with the mother, both generally and specifically in front of the child, than aunts or female family friends. In turn, these differences were associated directly and indirectly through maternal parenting with internalizing and externalizing problems. Clinical implications and future directions are discussed.

    This paper explores how changes in regulatory requirements for energy efficiency in buildings (in the US also known as building energy codes) affect household energy consumption. The focus in this paper is on natural gas consumption by Danish single-family owner-occupied houses. Unlike most other papers investigating household energy consumption this paper uses a unique panel data set constructed by merging several administrative data bases. The data set describes house and household characteristics, outdoor temperature and actual metered natural gas consumption over 6 years (1998-2003). Applying advanced econometric methods we examine differences in heating energy consumption due to different building regulation requirements at the time of house construction. As for the effect of the building regulation, we find that changes in Danish building regulations have led to significant reductions in energy used for heating. The latest revision of the Danish building regulation covered by this paper is that of 1998. This revision has resulted in a 7 percent reduction in natural gas consumption. (Author)

    Approximately 10% of amyotrophic lateral sclerosis (ALS) cases are familial (known as FALS) with an autosomal dominant inheritance pattern, and ~25% of FALS cases are caused by mutations in Cu/Zn superoxide dismutase (SOD1). There is convincing evidence that mutant SOD1 (mtSOD1) kills motor neurons (MNs) because of a gain-of-function toxicity, most likely related to aggregation of mtSOD1. A number of recent reports have suggested that antibodies can be used to treat mtSOD1-induced FALS. To follow up on the use of antibodies as potential therapeutics, we generated single chain fragments of variable region antibodies (scFvs) against SOD1, and then expressed them as 'intrabodies' within a motor neuron cell line. In the present study, we describe isolation of human scFvs that interfere with mtSOD1 in vitro aggregation and toxicity. These scFvs may have therapeutic potential in sporadic ALS, as well as FALS, given that sporadic ALS may also involve abnormalities in the SOD1 protein or activity. Copyright © 2013 Elsevier Inc.

    Familial subvalvular aortic stenosis (SAS) is one of the most common congenital heart defects in dogs and is an inherited defect of Newfoundlands, golden retrievers and human children. Although SAS is known to be inherited, specific genes involved in Newfoundlands with SAS have not been defined. We hypothesized that SAS in Newfoundlands is inherited in an autosomal dominant pattern and caused by a single genetic variant. We studied 93 prospectively recruited Newfoundland dogs, and 180 control dogs of 30 breeds. By providing cardiac screening evaluations for Newfoundlands we conducted a pedigree evaluation, genome-wide association study and RNA sequence analysis to identify a proposed pattern of inheritance and genetic loci associated with the development of SAS. We identified a three-nucleotide exonic insertion in phosphatidylinositol-binding clathrin assembly protein (PICALM) that is associated with the development of SAS in Newfoundlands. Pedigree evaluation best supported an autosomal dominant pattern of inheritance and provided evidence that equivocally affected individuals may pass on SAS in their progeny. Immunohistochemistry demonstrated the presence of PICALM in the canine myocardium and area of the subvalvular ridge. Additionally, small molecule inhibition of clathrin-mediated endocytosis resulted in developmental abnormalities within the outflow tract (OFT) of Xenopus laevis embryos. The ability to test for presence of this PICALM insertion may impact dog-breeding decisions and facilitate reduction of SAS disease prevalence in Newfoundland dogs. Understanding the role of PICALM in OFT development may aid in future molecular and genetic investigations into other congenital heart defects of various species.

Much less research, however, has focused specifically on the psychological well-being of single mothers who are employed, despite their growing presence in the labor force. Of the research which has considered employment, the focus has been on employment status per se rather than on other important work-related factors which may impact psychological health, such as psychosocial work quality and work-family conflict. The aim of this study was to: (1 compare employed single mothers and employed partnered mothers on measures of psychological distress, psychosocial work quality and work-family conflict; and (2 explore the potential role of work-family conflict and psychosocial work quality as explanations for any observed differences in psychological distress based on partner status. Method Analysis of data obtained from a cross-sectional telephone survey of employed parents in a mid-sized Western Canadian city. Analyses were based on 674 employed mothers (438 partnered and 236 single, who were 25-50 years old, with at least one child in the household. Results Compared to employed single mothers, employed partnered mothers were older, had more education and reported fewer hours of paid work. Single mothers reported higher levels of psychological distress, financial hardship, work-family conflict and poor psychosocial work quality. Statistical adjustment for income adequacy, psychosocial work quality and work-family conflict each independently resulted in single motherhood no longer being associated with psychological distress. Conclusions While single employed mothers did experience higher levels of psychological distress than their partnered counterparts, differences between these

    . The distinctive radiological signs and the X-linked mode of inheritance make it easy to diagnose. Here a four-generation Chinese SEDT family has been analyzed and the disease-causing mutation has been found. After polymerase chain reaction (PCR)-single strand conformation polymorphism (SSCP) analysis and DNA...... sequencing, a previously unreported deletion of T in exon 5 of SEDL gene (i.e. 293delT) was observed and seven individuals in the family carried the mutation. It results in frameshift and a putative truncated protein with the 97 N-terminal amino acids, and 9 changed amino acids. Therefore, loss of function...

    Ternes, M.P.

    2001-01-01

    During the winter of 1985-86, a retrofit field test was performed in 66 occupied, low-income, single-family homes in Madison, Wisconsin. The primary objectives of the field test were to (1) determine the measured energy savings and the relative benefits of a combination of envelope and mechanical equipment retrofits that were selected following a new audit-directed retrofit procedure, (2) determine the energy savings and benefits due to performing infiltration reduction work following a recently developed infiltration reduction procedure, and (3) study general occupant behavior and house thermal characteristics and their possible change following retrofit installation. This report provides an overview of the project and summarizes the findings which will be presented in detail in separate reports. Major findings from the field test include: (1) The audit-directed retrofit procedure produced an average savings of 207 therms/year/house. The procedure also more than doubled the overall cost-effectiveness of the low-income weatherization assistance program as compared with the priority system formerly used in Wisconsin. Wall insulation and condensing furnaces were the major retrofits (predicted annual energy savings greater than 100 therms/year) most often selected under the procedure. The respective average energy savings of the houses receiving wall insulation and condensing furnace. s was 14.6 and 14.3 therms/year for each$100 spent on them under the program. (2) The blower-door-guided infiltration reduction procedure reduced expenditures for infiltration reduction to about one-fourth of previous program costs (from$570/house to$106/house). The procedure also reduced the average air leakage rate in the treated houses by 16%, whereas, in a previous study, no significant reduction was found following the installation of typical infiltration reduction measures. (3) Twenty to 60% of the deviation between predicted and measured savings can be attributed to incorrect

  17. Multilocus genetic models of handedness closely resemble single-locus models in explaining family data and are compatible with genome-wide association studies.

    Right- and left-handedness run in families, show greater concordance in monozygotic than dizygotic twins, and are well described by single-locus Mendelian models. Here we summarize a large genome-wide association study (GWAS) that finds no significant associations with handedness and is consistent with a meta-analysis of GWASs. The GWAS had 99% power to detect a single locus using the conventional criterion of P < 5 × 10(-8) for the single locus models of McManus and Annett. The strong conclusion is that handedness is not controlled by a single genetic locus. A consideration of the genetic architecture of height, primary ciliary dyskinesia, and intelligence suggests that handedness inheritance can be explained by a multilocus variant of the McManus DC model, classical effects on family and twins being barely distinguishable from the single locus model. Based on the ENGAGE meta-analysis of GWASs, we estimate at least 40 loci are involved in determining handedness. © 2013 New York Academy of Sciences.

  19. Social anthropological and interdisciplinary research on the conversion of electrically heated single family houses to heating by combined pellet-solar systems

    Henning, Annette

    2004-01-01

    The social anthropological research presented here is part of the interdisciplinary research project PESTO, which focuses on the (partial or complete) conversion of single family houses from electric heating to heating by combined pellet-solar heating systems. Basic to this research is the assumption that it is more likely that energy conversions are carried through, and that they are successful on a long-term basis, if the new products are designed to fit as well as possible into the everyday lives of people. The anthropological interest in the project can be divided into two parts; motives for or against a conversion among men and women in Swedish households, and product design and placement in (previously) electrically heated single-family houses. Literature studies and semi-structured qualitative interviews are the main methods used in the anthropological part of the project. During the next 3-year project period, these investigations will be used to support information and marketing, and to formulate recommendations for conversion practice of electrically heated single-family houses to combined pellet-solar heating.

    Full Text Available The paper presents the results of a study of the psychological characteristics of boys and girls from complete and incomplete families. In addition to the type of family, the authors consider the educational tactics of mothers. The combined effects of the type of family and educational tactics on psychological characteristics of the adolescent were investigated. Adolescence was chosen as a period, when on the one hand, a relatively stable personality structure is developed, and on the other hand, the importance of the immediate social environment is extremely high. For our study we selected the psychological characteristics, to the utmost revealing the reaction of children to their parents' divorce: the level of subjective control (degree of responsibility for their own lives, and the sovereignty of the psychological space (clearnesse of psychological boundaries. It is shown that the largest influence on the psychological characteristics of adolescents, regardless of the type of family, is rendered by hostility in maternal education. The dependence of psychological characteristics of maternal directiveness occurs only at high values of such educational tactics that highlights the consistency of the obtained results with the classical studies of single-parent families.DOI: http://dx.doi.org/10.12731/2218-7405-2013-3-6

    2012-08-01

    Data from the 2002, 2006 and 2010 Scottish Health Behaviour in School-aged Children (HBSC) surveys were analysed using logistic multilevel regression for outcome variable irregular breakfast consumption (IBC). IBC prevalence in Scotland was higher among young people from reconstituted and single parent families, and particularly single father families. Family characteristics, found previously to be associated with breakfast consumption, such as number of siblings, perceived parenting, parental involvement and family affluence, differed by family structure. Family structure inequalities in IBC existed, also after adjustment for year and child's sex, age, grade and ethnicity. Across all family structures, IBC was more prevalent at the older age groups, among those who had difficult communication with their parents, and where household routines were infrequent. Greater number of siblings and lower family affluence were associated with higher odds of IBC in single mother and both parent families, while having a second home was associated with higher odds in reconstituted households. Fair parenting and being close to at least one parent was associated with reduced odds of IBC in single mother households, while being close to all parents was in single father households. In single mother homes, having a working mother was also positively associated with IBC. Family structure differences should be considered when addressing irregular breakfast consumption in adolescence. Copyright © 2012 Elsevier Ltd. All rights reserved.

    2005-01-01

    The diagnosis of hereditary non-polyposis colorectal cancer (HNPCC) is often confirmed by a mutation in one of several mismatch-repair genes, in particular MLH1, MSH2 and MSH6. Presymptomatic diagnosis requires the identification of a mutation causing the disease. Three different deletions......, identified after mutation screening of MSH2 and MLH1. All patients in the families were haplotyped using markers flanking the MSH2 gene. The haplotypes revealed that the five families with high probability descended from only two founders. The N596del segregated with the HNPCC phenotype with lod scores of 3.......2 and 2.0 at the recombination fraction of 0.0 in the two founder families. Sequencing of MSH2 and MLH1 did not reveal other pathogenic mutations, and N596del was not identified in 50 healthy controls. The mutation has previously been found expressed in mRNA, and is located in a conserved domain...

    A total of 452 samples from hot water systems of randomly selected single family residences in the suburbs of two German cities were analysed for the occurrence of Legionella. Technical data were documented using a standardized questionnaire to evaluate possible factors promoting the growth of the bacterium in these small plumbing systems. All houses were supplied with treated groundwater from public water works. Drinking water quality was within the limits specified in the German regulations for drinking water and the water was not chlorinated. The results showed that plumbing systems in private houses that provided hot water from instantaneous water heaters were free of Legionella compared with a prevalence of 12% in houses with storage tanks and recirculating hot water where maximum counts of Legionella reached 100,000 CFU/100ml. The presence of L. pneumophila accounted for 93.9% of all Legionella positive specimens of which 71.8% belonged to serogroup 1. The volume of the storage tank, interrupting circulation for several hours daily and intermittently raising hot water temperatures to >60 degrees C had no influence on Legionella counts. Plumbing systems with copper pipes were more frequently contaminated than those made of synthetic materials or galvanized steel. An inhibitory effect due to copper was not present. Newly constructed systems (water preparation had a marked influence. More than 50% of all houses using district heating systems were colonized by Legionella. Their significantly lower hot water temperature is thought to be the key factor leading to intensified growth of Legionella. Although hot water systems using solar energy to supplement conventional hot water supplies operate at temperatures 3 degrees C lower than conventional systems, this technique does not seem to promote proliferation of the bacterium. Our data show convincingly that the temperature of the hot water is probably the most important or perhaps the only determinant factor for

    Investigate neurodevelopmental outcomes at 3 years corrected age in infants with a birth weight ≤1250 g born to single parents. Infants born between 1995 and 2010 with a birth weight ≤1250 g were considered eligible. Primary outcome was neurodevelopmental impairment; considered present if a child had any of the following: cerebral palsy, cognitive delay, visual impairment, or deafness/neurosensory hearing impairment. Univariate and multivariate analyses were performed. A total of 1900 infants were eligible for inclusion. Follow-up data were available for 1395; 88 were born to a single parent. Infants in the single-parent group had higher mortality (18% vs. 11%, p = 0.009), IQ ≥1 SD below the mean (40% vs. 21%, p = 0.001) and any neurodevelopmental impairment (47% vs. 29%, p = 0.003). Single-parent family status, maternal education, bronchopulmonary dysplasia and severe neurological injury were significant predictors of intellectual impairment at 3 years corrected age. Preterm infants with a birth weight ≤1250 g born to single parents at birth have poorer intellectual functioning at 3 years corrected age.

    Women with a significant family history of breast cancer are often offered more intensive and earlier surveillance than is offered to the general population in the National Breast Screening Programme. Up to now, this strategy has not been fully evaluated. To evaluate the benefit of mammographic surveillance for women aged 40-49 years at moderate risk of breast cancer due to family history. The study is referred to as FH01. This was a single-arm cohort study with recruitment taking place between January 2003 and February 2007. Recruits were women aged women were offered annual mammography for at least 5 years and observed for the occurrence of breast cancer during the surveillance period. The age group 40-44 years was targeted so that they would still be aged women, 94% of whom were aged women aged 40-49 years with a significant family history of breast or ovarian cancer is both clinically effective in reducing breast cancer mortality and cost-effective. There is a need to further standardise familial risk assessment, to research the impact of digital mammography and to clarify the role of breast density in this population.

    Bone health may be negatively impacted by childhood socio-environmental circumstances. We examined the independent associations of single-parent childhood and parental death or divorce in childhood with adult bone strength indices. Longer exposure to a single-parent household in childhood was associated with lower bone strength in adulthood. Because peak bone mass is acquired during childhood, bone health may be negatively impacted by childhood socio-environmental disadvantage. The goal of this study was to determine whether being raised in a single-parent household is associated with lower bone strength in adulthood. Using dual-energy X-ray absorptiometry data from 708 participants (mean age 57 years) in the Midlife in the United States Biomarker Project, we examined the independent associations of composite indices of femoral neck bone strength relative to load (in three failure modes: compression, bending, and impact) in adulthood with the experience of single-parent childhood and parental death or divorce in childhood. After adjustment for gender, race, menopause transition stage, age, and body mass index, each additional year of single-parent childhood was associated with 0.02 to 0.03 SD lower indices of adult femoral neck strength. In those with 9-16 years of single-parent childhood, the compression strength index was 0.41 SD lower, bending strength index was 0.31 SD lower, and impact strength index was 0.25 SD lower (all p values divorce during childhood was not by itself independently associated with adult bone strength indices. The magnitudes of these associations were unaltered by additional adjustment for lifestyle factors and socioeconomic status in childhood and adulthood. Independent of parental death or divorce, growing up in a single-parent household is associated with lower femoral neck bone strength in adulthood, and this association is not entirely explained by childhood or adult socioeconomic conditions or lifestyle choices.

    The health and well-being of single-parent families living in violent neighbourhoods in US cities who participate in housing programmes is not well described. This two-phase, mixed-methods study explores the health status of families who were participants in a housing-plus programme in Philadelphia, Pennsylvania between 2011 and 2013 and the relationship between the characteristics of the neighbourhoods in which they lived and their perceptions of well-being and safety. In phase 1, data collected with standardised health status instruments were analysed using descriptive statistics and independent sample t-tests to describe the health of single parents and one randomly selected child from each parent's household in comparison to population norms. In a subset of survey respondents, focus groups were conducted to generate an in-depth understanding of the daily lives and stressors of these families. Focus group data were analysed using content analysis to identify key descriptive themes. In phase 2, daily activity path mapping, surveys and interviews of parent-child dyads were collected to assess how these families perceive their health, neighbourhood and the influence of neighbourhood characteristics on the families' day-to-day experience. Narratives and activity maps were combined with crime data from the Philadelphia Police Department to analyse the relationship between crime and perceptions of fear and safety. Phase 1 data demonstrated that parent participants met or exceeded the national average for self-reported physical health but fell below the national average across all mental health domains. Over 40% reported moderate to severe symptoms of depression. Parents described high levels of stress resulting from competing priorities, financial instability, and concern for their children's well-being and safety. Analysis of phase 2 data demonstrated that neighbourhood characteristics exert influence over parents' perceptions of their environment and how they permit

    A pilot project of the solar water heating system combined with a low temperature air source heat pump (ASHP) unit was established in 2014 in a detached residential house in the rural region of Beijing, in order to investigate the system application prospect for single family houses via system...... optimization design and economic analysis. The established system was comprised of the glass heat-pipe based evacuated tube solar collectors with a gross area of 18.8 m2 and an ASHP with a stated heating power of 8 kW for the space heating of a single family rural house of 81.4 m2. The dynamic thermal...... with good building insulation were undertaken to figure out the system economical efficiency in the rural regions of Beijing. The results show that the payback periods of the solar space heating system combined with the ASHP with the collector areas 15.04-22.56 m2 are 17.3-22.4 years for the established...

  3. Optimized Use of Low-Depth Genotyping-by-Sequencing for Genomic Prediction Among Multi-Parental Family Pools and Single Plants in Perennial Ryegrass (Lolium perenne L.

    Full Text Available Ryegrass single plants, bi-parental family pools, and multi-parental family pools are often genotyped, based on allele-frequencies using genotyping-by-sequencing (GBS assays. GBS assays can be performed at low-coverage depth to reduce costs. However, reducing the coverage depth leads to a higher proportion of missing data, and leads to a reduction in accuracy when identifying the allele-frequency at each locus. As a consequence of the latter, genomic relationship matrices (GRMs will be biased. This bias in GRMs affects variance estimates and the accuracy of GBLUP for genomic prediction (GBLUP-GP. We derived equations that describe the bias from low-coverage sequencing as an effect of binomial sampling of sequence reads, and allowed for any ploidy level of the sample considered. This allowed us to combine individual and pool genotypes in one GRM, treating pool-genotypes as a polyploid genotype, equal to the total ploidy-level of the parents of the pool. Using simulated data, we verified the magnitude of the GRM bias at different coverage depths for three different kinds of ryegrass breeding material: individual genotypes from single plants, pool-genotypes from F2 families, and pool-genotypes from synthetic varieties. To better handle missing data, we also tested imputation procedures, which are suited for analyzing allele-frequency genomic data. The relative advantages of the bias-correction and the imputation of missing data were evaluated using real data. We examined a large dataset, including single plants, F2 families, and synthetic varieties genotyped in three GBS assays, each with a different coverage depth, and evaluated them for heading date, crown rust resistance, and seed yield. Cross validations were used to test the accuracy using GBLUP approaches, demonstrating the feasibility of predicting among different breeding material. Bias-corrected GRMs proved to increase predictive accuracies when compared with standard approaches to

    Although child neglect and substance abuse co-occur in greater than 60% of child protective service cases, intervention outcome studies are deplorably lacking. Therefore, a home-based Family Behavior Therapy is described in the treatment of a woman evidencing child neglect, substance dependence, domestic violence and other co-occurring problems. Treatment included contingency management, self control, stimulus control, communication and child management skills training exercises, and financial management components. Results indicated improvements in child abuse potential, home hazards, domestic violence, and drug use, which were substantiated by objective urinalysis testing, and tours of her home. Validity checks indicated the participant was being truthful in her responses to standardized questionnaires, and assessors were “blind” to study intent. Limitations (i.e., lack of experimental control and follow-up data collection) of this case example are discussed in light of these results. PMID:23226920

    Usher syndrome is rare genetic disorder impairing two human senses, hearing and vision, with the characteristic late onset of vision loss. This syndrome is divided into three types. In all cases, the vision loss is postlingual, while loss of hearing is usually prelingual. The vestibular functions may also be disturbed in Usher type 1 and sometimes in type 3. Vestibular areflexia is helpful in making a proper diagnosis of the syndrome, but, often, the syndrome is misdiagnosed as a nonsyndromic hearing loss. Here, we present a Polish family with hearing loss, which was clinically classified as nonsyndromic. After excluding mutations in the DFNB1 locus, we implemented the next-generation sequencing method and revealed that hearing loss was syndromic and mutations in the USH2A gene indicate Usher syndrome. This research highlights the importance of molecular analysis in establishing a clinical diagnosis of congenital hearing loss.

    Nuclear factor-κB (NF-κB) family plays an important role in the development of sepsis in critically ill patients. Although several single nucleotide polymorphisms (SNPs) have been identified in the NF-κB family genes, only a few SNPs have been studied. A total of 753 patients with major blunt trauma were included in this study. Tag SNPs (tSNPs) were selected from the NF-κB family genes (NFKB1, NFKB2, RELA, RELB and REL) through construction of haplotype blocks. The SNPs selected from genes within the canonical NF-κB pathway (including NFKB1, RELA and REL), which played a critical role in innate immune responses were genotyped using pyrosequencing method and analyzed in relation to the risk of development of sepsis and multiple organ dysfunction (MOD) syndrome. Moreover, the rs842647 polymorphism was analyzed in relation to tumor necrosis factor α (TNF-α) production by peripheral blood leukocytes in response to bacterial lipoprotein stimulation. Eight SNPs (rs28362491, rs3774932, rs4648068, rs7119750, rs4803789, rs12609547, rs1560725 and rs842647) were selected from the NF-κB family genes. All of them were shown to be high-frequency SNPs in this study cohort. Four SNPs (rs28362491, rs4648068, rs7119750 and rs842647) within the canonical NF-κB pathway were genotyped, and rs842647 was associated with sepsis morbidity rate and MOD scores. An association was also observed between the rs842647 A allele and lower TNF-α production. rs842647 polymorphism might be used as relevant risk estimate for the development of sepsis and MOD syndrome in patients with major trauma.

    The industrial and transportation revolutions of nineteenth-century America separated work from home (at least for the growing middle class) and intensified the development of masculine and feminine spheres devoted to success and domesticity, respectively. This development tended to reduce the husband's traditional patriarchal roles to that of provider only, while leaving the wife and mother with enhanced authority over household management and child rearing, a development with consequences for feminism. This article examines two extreme cases of separation of work from home: absent husbands, respected professional men, who left their wives alone for months or years and, while they provided financial support, surrendered all household authority to "single" wives.

    Tetrairon(III) Single-Molecule Magnets (SMMs) with a propeller-like structure exhibit tuneable magnetic anisotropy barriers in both height and shape. The clusters [Fe4(L1)2(dpm)6] (1), [Fe4(L2)2(dpm)6] (2), [Fe4(L3)2(dpm)6].Et2O (3.Et2O), and [Fe4(OEt)3(L4)(dpm)6] (4) have been prepared by reaction of [Fe4(OMe)6(dpm)6] (5) with tripodal ligands R-C(CH2OH)3 (H3L1, R = Me; H3L2, R = CH2Br; H3L3, R = Ph; H3L4, R = tBu; Hdpm = dipivaloylmethane). The iron(III) ions exhibit a centered-triangular topology and are linked by six alkoxo bridges, which propagate antiferromagnetic interactions resulting in an S = 5 ground spin state. Single crystals of 4 reproducibly contain at least two geometric isomers. From high-frequency EPR studies, the axial zero-field splitting parameter (D) is invariably negative, as found in 5 (D = -0.21 cm(-1)) and amounts to -0.445 cm(-1) in 1, -0.432 cm(-1) in 2, -0.42 cm(-1) in 3.Et2O, and -0.27 cm(-1) in 4 (dominant isomer). The anisotropy barrier Ueff determined by AC magnetic susceptibility measurements is Ueff/kB = 17.0 K in 1, 16.6 K in 2, 15.6 K in 3.Et2O, 5.95 K in 4, and 3.5 K in 5. Both |D| and U(eff) are found to increase with increasing helical pitch of the Fe(O2Fe)3 core. The fourth-order longitudinal anisotropy parameter B4(0), which affects the shape of the anisotropy barrier, concomitantly changes from positive in 1 ("compressed parabola") to negative in 5 ("stretched parabola"). With the aid of spin Hamiltonian calculations the observed trends have been attributed to fine modulation of single-ion anisotropies induced by a change of helical pitch.

    Blended phenotypes or co-occurrence of independent phenotypically distinct conditions are extremely rare and are due to coincidence of multiple pathogenic mutations, especially due to consanguinity. Hereditary fibrinogen deficiencies result from mutations in the genes FGA, FGB, and FGG, encoding the three different polypeptide chains that comprise fibrinogen. Neurodevelopmental abnormalities have not been associated with fibrinogen deficiencies. In this study, we report an unusual patient with a combination of two independently inherited genetic conditions; fibrinogen deficiency and early onset cortical atrophy. The study describes a male child from consanguineous family presented with hypofibrinogenemia, diffuse cortical atrophy, microcephaly, hypertonia and axonal motor neuropathy. Through a combination of homozygosity mapping and exome sequencing, we identified bi-allelic pathogenic mutations in two genes: a homozygous novel truncating mutation in FGG (c.554del; p.Lys185Argfs*14) and a homozygous missense mutation in TBCD (c.1423G > A;p.Ala475Thr). Loss of function mutations in FGG have been associated with fibrinogen deficiency, while the c.1423G > A mutation in TBCD causes a novel syndrome of neurodegeneration and early onset encephalopathy. Our study highlights the importance of homozygosity mapping and exome sequencing in molecular prenatal diagnosis, especially when multiple gene mutations are responsible for the phenotype.

    Full Text Available As part of their struggle against inequality and social exclusion, many countries are trying to reform their redistributive system and low-income support measures to encourage return to work, and reduce inactivity traps. The purpose of this article is to propose a reflection on the social and fiscal policies. The analysis focuses on three measures in three different countries: the Earned Income Tax Credit (EITC in the United States, the Working Tax Credit (WTC in the UK and the Active Solidarity Income (RSA in France. The emphasis is placed on the effects of such policies on the situation of single parents, in particular as part of their transition from welfare (social assistance to the labor market.

    The report gives, for the first time, results of an extensive study of the effect of ventilation on radon concentrations and radon entry rate in a single-family dwelling. Measurements of radon concentrations, building dynamics, and environmental parameters made in Princeton University research houses over several seasons and under different building operating conditions show the functional dependence of radon entry rate on basement depressurization. The work clarifies the role of natural ventilation in reducing indoor radon concentrations. The work shows conclusively that natural ventilation can decrease radon levels two ways: (1) by simple dilution, and (2) by providing a pressure break (defined as any opening in the building shell that reduces the outdoor/indoor differential pressure). This reduces building depressurization and thus the amount of radon-contaminated soil gas that is drawn into the building

    VNG - Verbundnetz Gas Aktiengesellschaft of Leipzig, Germany, has pioneered the development of a decentral home energy system combining very high efficiencies with extremely low emissions. The company has installed the world`s first fuel cell total energy system using natural gas as an energy source to generate both heat and power in a single-family home. It replaces the gas-fired mini power station operated as part of the VNG natural gas house project which was instrumental in the rapid advancement of small-scale co-generation technology. The objective of VNG and its project partners is to collect reliable data for advancing fuel cell technology development, allowing appliance manufacturers to design a competitive system for introduction on the market within a few years. Discerning consumers will then be able to opt for an innovative, highly efficient system to meet all their household energy needs. (orig.)

  14. A Meta-Analysis of Single-Family Deep Energy Retrofit Performance in the U.S.

    Energy Technology Data Exchange (ETDEWEB)

    Less, Brennan; Walker, Iain

    2014-03-01

    The current state of Deep Energy Retrofit (DER) performance in the U.S. has been assessed in 116 homes in the United States (US), using actual and simulated data gathered from the available domestic literature. Substantial airtightness reductions averaging 63% (n=48) were reported (two- to three-times more than in conventional retrofits), with average post-retrofit airtightness of 4.7 Air Changes per House at 50 Pascal (ACH50) (n=94). Yet, mechanical ventilation was not installed consistently. In order to avoid indoor air quality (IAQ) issues, all future DERs should comply with ASHRAE 62.2-2013 requirements or equivalent. Projects generally achieved good energy results, with average annual net-site and net-source energy savings of 47%±20% and 45%±24% (n=57 and n=35), respectively, and carbon emission reductions of 47%±22% (n=23). Net-energy reductions did not vary reliably with house age, airtightness, or reported project costs, but pre-retrofit energy usage was correlated with total reductions (MMBtu). Annual energy costs were reduced $1,283±$804 (n=31), from a pre-retrofit average of $2,738±$1,065 to $1,588±$561 post-retrofit (n=25 and n=39). The average reported incremental project cost was $40,420±$30,358 (n=59). When financed on a 30-year term, the median change in net-homeownership cost was only $1.00 per month, ranging from $149 in savings to an increase of $212 (mean=$15.67±$87.74; n=28), and almost half of the projects resulted in reductions in net-cost. The economic value of a DER may be much greater than is suggested by these net-costs, because DERs entail substantial non-energy benefits (NEBs), and retrofit measures may add value to a home at resale similarly to general remodeling, PV panel installation, and green/energy efficient home labels. These results provide estimates of the potential of DERs to address energy use in existing homes across climate zones that can be used in future estimates of the technical potential to reduce household

    2014-07-01

    On the basis of data from KiGGS Wave 1, the following manuscript investigates potential differences in the health status of children and adolescents aged 3-17 years according to the family form they live in: nuclear, single-parent, or stepfamily (n = 10,298). Additionally, we investigate whether differences persist after controlling for age, gender, living area, parental social status, and getting along in the family. Parent-rated health, chronic diseases, emotional or behavior problems, health-related quality of life, and daily consumption of fruits and vegetables were analyzed (prevalence, odds ratios). While the parent-rated health was independent of the family form, the prevalence of the other outcomes differed significantly according to the family form. Emotional or behavior problems were measured more often among children and adolescents growing up in single-parent families (OR 1.62; 95% CI 1.17-2.26) or stepfamily households (OR 2.36; 95% CI 1.63-3.41) than among those growing up in nuclear families, after adjusting for age, gender, living area, social status, and getting along in the family. Additionally, children and adolescents from single-parent families had chronic diseases (OR 1.53; 95% CI 1.20-1.96) more often than their counterparts who lived together with both parents. Compared with those growing up in nuclear families, children and adolescents from stepfamilies showed a greater risk of lower health-related quality of life (OR 2.91; 95% CI 1.76-4.80) and of lower daily consumption of fruits and vegetables (OR 1.30; 95% CI 1.01-1.67). The results indicate the importance of the family context for the health of children and adolescents.

One issue is that commonly used questionnaires are multidimensional, but expressed as summary scores. Using the example of low back pain (LBP, the aim of this study was to explore and descriptively compare the application of LCA when using questionnaire summary scores and when using single items to subgrouping of patients based on multidimensional data. Materials and methods: Baseline data from 928 LBP patients in an observational study were classified into four health domains (psychology, pain, activity, and participation using the World Health Organization’s International Classification of Functioning, Disability, and Health framework. LCA was performed within each health domain using the strategies of summary-score and single-item analyses. The resulting subgroups were descriptively compared using statistical measures and clinical interpretability. Results: For each health domain, the preferred model solution ranged from five to seven subgroups for the summary-score strategy and seven to eight subgroups for the single-item strategy. There was considerable overlap between the results of the two strategies, indicating that they were reflecting the same underlying data structure. However, in three of the four health domains, the single-item strategy resulted in a more nuanced description, in terms

    Bioethicists disagree over methods, theories, decision-making guides, case analyses and public policies. Thirty years ago, the thinking of many scholars coalesced around a principlist approach to bioethics. That mid-level mode of moral reasoning is now one of many approaches to moral deliberation. Significant variation in contemporary approaches to the study of ethical issues related to medicine, biotechnology and health care raises the question of whether bioethics exists as widely shared method, theory, normative framework or mode of moral reasoning.

    2012-08-15

    There are about 1.1 million single-family houses in Finland. 75% of these houses were built before year 1990. Majority of the houses remain at the energy- and eco-efficiency level of their construction time. If all of these houses were renovated to meet the state-of-the- art energy-efficiency requirements, the savings in nationwide consumption of heating energy would be 11.8 TWh. There are lots of typical single-family houses in the Finnish housing stock from the construction period. Renovation concepts with typical solutions can be developed for these typical houses. However, it must always be ensured that the selected concept suits the particular house. Comprehensive, full-service or one-stop-shop service models can be developed based on the renovation concepts. These may also include other services such as a building condition survey or a study, energy certificate, equipment and system installations, financial services, operation and maintenance services, and energy-monitoring and consumption analysis. It is natural to connect the one-stop-shop service model into the renovation process. The process includes stages for marketing, preliminary building inspection and energy audit, a detailed building inspection and energy analysis, a proposal for an integrated solution, the actual repair work, and quality assurance and continuous commissioning. Different stages involve different actors and service providers. There are several options for which type of organization or agent takes the main responsibility for the one-stop-shop service. Depending on the responsible organization, the content provider's business model and priorities differ. The one-stop-shop services business has been a narrow part of actors' whole business, so far. Some actors have already stopped providing the services, either due to the lack of demand or unprofitableness of the services. In an ideal model, the value promise and the main features of the model are the same, but the service

    2014-07-01

    Research supports that child parent relationship therapy (CPRT), a filial therapy approach, has strong effects on participating parents and children. Some speculate that filial therapy improves the family system; however, minimal research exists to support this claim. Using a single-case design, researchers examined CPRT's impact on the functioning of 8 families. Results revealed that 6 families experienced statistically significant improvements in targeted areas of family functioning. Results from self-reported measures indicated that 7 families improved in family satisfaction, 4 in cohesion, 3 in communication, and 1 in flexibility. Observational measures also revealed improvements: 5 families in flexibility, 4 families in cohesion, and 4 families in communication. The results support that the benefits of CPRT may extend to the family system. © 2013 American Association for Marriage and Family Therapy.

  6. Single Nucleotide Polymorphisms in Taste Receptor Genes Are Associated with Snacking Patterns of Preschool-Aged Children in the Guelph Family Health Study: A Pilot Study

    Full Text Available Snacking is an integral component of eating habits in young children that is often overlooked in nutrition research. While snacking is a substantial source of calories in preschoolers’ diets, there is limited knowledge about the factors that drive snacking patterns. The genetics of taste may help to better understand the snacking patterns of children. The rs1761667 single nucleotide polymorphism (SNP in the CD36 gene has been linked to fat taste sensitivity, the rs35874116 SNP in the TAS1R2 gene has been related to sweet taste preference, and the rs713598 SNP in the TAS2R38 gene has been associated with aversion to bitter, green leafy vegetables. This study seeks to determine the cross-sectional associations between three taste receptor SNPs and snacking patterns among preschoolers in the Guelph Family Health Study. Preschoolers’ snack quality, quantity, and frequency were assessed using three-day food records and saliva was collected for SNP genotyping (n = 47. Children with the TT genotype in TAS1R2 consumed snacks with significantly more calories from sugar, and these snacks were consumed mostly in the evening. Total energy density of snacks was highest in the CC and CG genotypes compared to the GG genotype in TAS2R38, and also greater in the AA genotype in CD36 compared to G allele carriers, however this difference was not individually attributable to energy from fat, carbohydrates, sugar, or protein. Genetic variation in taste receptors may influence snacking patterns of preschoolers.

    Full Text Available System cost reductions and development of standardised plug-and-function systems are some of the most important goals for solar heating technology development. Retrofitting hot water boilers in single-family houses when installing solar collectors has the potential to significantly reduce both material and installation costs. In this study, the TRNSYS simulation models of the retrofitting solar thermal system were validated against measurements. Results show that the validated models are in good agreement with measurements. On an annual basis a deviation of 2.5% out of 1099 kWh was obtained between the auxiliary energy from results and from the simulation model for a complete system. Using the validated model a system optimization was carried out with respect to control strategies for auxiliary heating, heat losses and volume of auxiliary storage. A sensitivity analysis was carried out regarding different volumes of retrofitted hot water boiler, DHW profiles and climates. It was estimated that, with adequate improvements, extended annual solar fractions of 60%, 78% and 81% can be achieved for Lund (Sweden, Lisbon (Portugal and Lusaka (Zambia, respectively. The correspondent collector area was 6, 4 and 3 m2, respectively. The studied retrofitted system achieves a comparable performance with conventional solar thermal systems with the potential to reduce the investment cost.

    Indoor thermal conditions and energy performance were simulated, by the aid of EESLISM as a common simulation program for indoor thermal conditions and energy systems, for an actual two-storied single family house equipped with solar-heated floors and a domestic hot water (DHW) heating system, in order to investigate applicability of the simulation program. The house, built in Shibuya Ward in Tokyo, has a total floor area of 164m{sup 2}, with a living room, dining room and study heated by the solar system for a total floor area of 35m{sup 2}. A heat-storage tank is provided, dedicated to the DHW system. The solar collector is of flat type, with selectively light-absorbing planes, having a total collector area of 11.46m{sup 2}. The operating conditions of the floor-heating and DHW systems are almost reproduced. It is necessary to take surrounding conditions into consideration; solar radiation in daytime will be overestimated if adjacent buildings are neglected to give higher temperature in the space and on the wall on the south than the observed level. 6 refs., 5 figs., 1 tab.

    Full Text Available The paper presents energy use for heating and ventilation (one of the energy performance components determined in three ways. A case of a single family building located near Wroclaw in Poland is analyzed. The first and the second variant are both computational and the third presents actual measured energy consumption. Computational variants are based on the Polish methodology for the EPC (the Energy Performance Certificate. This methodology is based on ‘the Energy Performance of Buildings Directive 2010/31/EU’. Energy use for heating and ventilation is calculated using monthly method presented in EN ISO 13790. In the first computational option standard input data (parameters such as indoor and outdoor air temperature etc. are taken from standards and regulations are implemented. In the second variant this input data are partially taken from measurements. The results of energy use from both computational variants are compared to the actual measured energy consumption. On the basis of this comparison the influence of three factors: solar radiation heat gains, building air tightness and the SCOP of the heat pump on energy use calculations are analyzed. Conclusions aim to point the differences between them and the actual energy consumption.

    Full Text Available It is well known that the notion of measure and integral were released early enough in close connection with practical problems of measuring of geometric figures. Notion of measure was outlined in the early 20th century through H. Lebesgue’s research, founder of the modern theory of measure and integral. It was developed concurrently a technique of integration of functions. Gradually it was formed a specific area todaycalled the measure and integral theory. Essential contributions to building this theory was made by a large number of mathematicians: C. Carathodory, J. Radon, O. Nikodym, S. Bochner, J. Pettis, P. Halmos and many others. In the following we present several abstract sets, classes of sets. There exists the sets which are not Lebesgue measurable and the sets which are Lebesgue measurable but are not Borel measurable. Hence B ⊂ L ⊂ P(X.

    Supergiant Fast X-ray Transients (SFXTs) are one of the most interesting (and unexpected) results of the INTEGRAL mission. They are a new class of HMXBs displaying short hard X-ray outbursts (duration less tha a day) characterized by fast flares (few hours timescale) and large dinamic range (10E3-10E4). The physical mechanism driving their peculiar behaviour is still unclear and highly debated: some models involve the structure of the supergiant companion donor wind (likely clumpy, in a spherical or non spherical geometry) and the orbital properties (wide separation with eccentric or circular orbit), while others involve the properties of the neutron star compact object and invoke very low magnetic field values (B 1E14 G, magnetars). The picture is still highly unclear from the observational point of view as well: no cyclotron lines have been detected in the spectra, thus the strength of the neutron star magnetic field is unknown. Orbital periods have been measured in only 4 systems, spanning from 3.3 days to 165 days. Even the duty cycle seems to be quite different from source to source. The Energetic X-ray Imaging Survey Telescope (EXIST), with its hard X-ray all-sky survey and large improved limiting sensitivity, will allow us to get a clearer picture of SFXTs. A complete census of their number is essential to enlarge the sample. A long term and continuous as possible X-ray monitoring is crucial to -(1) obtain the duty cycle, -(2 )investigate their unknown orbital properties (separation, orbital period, eccentricity),- (3) to completely cover the whole outburst activity, (4)-to search for cyclotron lines in the high energy spectra. EXIST observations will provide crucial informations to test the different models and shed light on the peculiar behaviour of SFXTs.

    Profilicollis chasmagnathi Holcman-Spector, Mañé-Garzón & Dei-Cas, 1977 (Acanthocephala: Polymorphidae) has been reported to parasitise different grapsid species as intermediate hosts along the South Atlantic shores, i.e. Cyrtograpsus angulatus (Dana) and Neohelice granulata (Dana) in Uruguay and Cyrtograpsus altimanus (Rathbun) in Argentina. Larvae of a similar acanthocephalan described as Profilicollis antarcticus Zdzitowiecki, 1985 were recorded in the crab Hemigrapsus crenulatus (Milne-Edwards) from an estuarine habitat on the Southeast Pacific shore in Chile. Earlier studies have questioned the specific assignation of the Chilean estuarine populations of Profilicollis Meyer, 1931. The aim of this study was to re-examine the identification of these acanthocephalans by means of morphological and molecular analyses of cystacanths of Profilicollis spp. gathered from C. angulatus, N. granulata, C. altimanus and H. crenulatus. Our analyses showed that a single species of Profilicollis, P. chasmagnathi, parasitises these four crab species. The assessment of specimens from the South Shetlands Islands, the type-locality of P. antarcticus, is needed before formally proposing that P. antarcticus is a junior subjective synonym of P. chasmagnathi.

    A series of structurally related pseudocubic metal cyanide clusters of Re(II) and 3d metal ions [{MX}4{Re(triphos)(CN)3}4] (M = Mn, Fe, Co, Ni, Zn; X = Cl, I, -OCH3) have been prepared, and their magnetic and electrochemical properties have been probed to evaluate the effect of changing the identity of the 3d metal ion. Electrochemistry of the clusters reveals several rhenium-based oxidation and reduction processes, some of which result in cluster fragmentation. The richest electrochemistry was observed for the iron congener, which exists as the Re(I)/Fe(III) cluster at the resting potential and exhibits six clear one-electron reversible redox couples and two, closely spaced one-electron quasi-reversible processes. The [{MnIICl}4{ReII(triphos)(CN)3}4] complex exhibits single molecule magnetism with a fast tunneling relaxation process observed at H = 0 determined by micro-SQUID magnetization measurements. A comparative evaluation of the magnetic properties across the series reveals that the compounds exhibit antiferromagnetic coupling between the metal ions, except for [{NiIICl}4{ReII(triphos)(CN)3}4] that shows ferromagnetic behavior. Despite the large ground-state spin value of [{NiIICl}4{ReII(triphos)(CN)3}4] (S = 6), only manganese congeners exhibit SMM behavior to 1.8 K.

    This paper addresses the viability of converting single-family residential buildings in Brazil into zero energy buildings (ZEBs). The European Union and the United States aim ZEBs implementation to address ‘peak oil’ and environmental concerns. However, literature shows no agreement on a consensual definition of ZEB. Seeking a Brazilian ZEB definition, this paper addresses PassivHaus and thermal comfort standards for hot climates, source metrics for ZEB, Brazil′s energy mix, residential energy end uses and Brazilian legal framework for residential photovoltaic (PV) generation. Internal Rate of Return for PV systems in two Brazilian cities is calculated under various scenarios. It shows grid parity was reached from April 2012 to November 2012 assuming residential electric tariffs of that period and the financial conditions given by the Brazilian government for the construction of new dams in the Amazon and the lowest rates offered by Brazilian banks to private individuals. Governmental decision to lower electric residential tariffs in November 2012 reduced the scope of grid parity. Later revocation of a tax exemption in April 2013 ended grid parity in Brazil. It concludes, conversely to developed countries, it is the volatile Brazilian energy policy, instead of economical barriers, the main obstacle for ZEB viability in Brazil. - Highlights: • Critique on super insolated buildings as a good solution for hot climates. • PV parity already reached in some parts of Brazil. • Proposal for a zero energy building definition for Brazil. • Critique of the source metric for energy balance in zero energy buildings. • Average roof area in Brazil enough for PV array to meet average energy consumption

    An evaluation of a variety of efficient water heating strategies for an all-electric single family home located in a mixed-humid climate is conducted using numerical modeling. The strategies considered include various combinations of solar thermal, heat pump, and electric resistance water heaters. The numerical model used in the study is first validated against a year of field data obtained on a dual-tank system with a solar thermal preheat tank feeding a heat pump water heater that serves as a backup. Modeling results show that this configuration is the most efficient of the systems studied over the course of a year, with a system coefficient of performance (COP sys ) of 2.87. The heat pump water heater alone results in a COP sys of 1.9, while the baseline resistance water heater has a COP sys of 0.95. Impacts on space conditioning are also investigated by considering the extra energy consumption required of the air source heat pump to remove or add heat from the conditioned space by the water heating system. A modified COP sys that incorporates the heat pump energy consumption shows a significant drop in efficiency for the dual tank configuration since the heat pump water heater draws the most heat from the space in the heating season while the high temperatures in the solar storage tank during the cooling season result in an added heat load to the space. Despite this degradation in the COP sys , the combination of the solar thermal preheat tank and the heat pump water heater is the most efficient option even when considering the impacts on space conditioning.

    The exact mode of transmission of leprosy is not clearly understood; however, many studies have demonstrated active transmission of leprosy around a source case. Families of five active leprosy cases and their household contacts were chosen from a high endemic area in Purulia. Fifty-two soil samples were also collected from different areas of their houses. DNA was extracted from slit-skin smears (SSS) and soil samples and the Mycobacterium leprae-specific RLEP (129 bp) region was amplified using PCR. Molecular typing of M. leprae was performed for all RLEP PCR-positive samples by single nucleotide polymorphism (SNP) typing and confirmation by DNA sequencing. SSS of these five patients and six out of the total 28 contacts were PCR positive for RLEP whereas 17 soil samples out of 52 showed the presence of M. leprae DNA. SNP typing of M. leprae from all RLEP PCR-positive subjects (patients and smear-positive contacts) and 10 soil samples showed the SNP type 1 genotype. M. leprae DNA from the five leprosy patients and the six contacts was further subtyped and the D subtype was noted in all patients and contacts, except for one contact where the C subtype was identified. Typing followed by subtyping of M. leprae clearly revealed that either the contacts were infected by the patients or both patients and contacts had the same source of infection. It also revealed that the type of M. leprae in the soil in the inhabited areas where patients resided was also of the same type as that found in patients. © 2013 The Authors Clinical Microbiology and Infection © 2013 European Society of Clinical Microbiology and Infectious Diseases.

    The potential benefits of hydrogen as a transportation fuel will not be achieved until hydrogen vehicles capture a substantial market share. However, although hydrogen fuel cell vehicle (FCV) technology has been making rapid progress, the lack of a hydrogen infrastructure remains a major barrier for FCV adoption and commercialization. The high cost of building an extensive hydrogen station network and the foreseeable low utilization in the near term discourages private investment. Based on the past experience of fuel infrastructure development for motor vehicles, innovative, distributed, small-volume hydrogen refueling methods may be required to refuel FCVs in the near term. Among small-volume refueling methods, home and neighborhood tri-generation systems (systems that produce electricity and heat for buildings, as well as hydrogen for vehicles) stand out because the technology is available and has potential to alleviate consumer's fuel availability concerns. In addition, it has features attractive to consumers such as convenience and security to refuel at home or in their neighborhood. The objective of this paper is to provide analytical tools for various stakeholders such as policy makers, manufacturers and consumers, to evaluate the design and the technical, economic, and environmental performances of tri-generation systems for home and neighborhood refueling. An interdisciplinary framework and an engineering/economic model is developed and applied to assess home tri-generation systems for single family residences (case studies on neighborhood systems will be provided in a later paper). Major tasks include modeling yearly system operation, exploring the optimal size of a system, estimating the cost of electricity, heat and hydrogen, and system CO{sub 2} emissions, and comparing the results to alternatives.

    In the Swedish Building Energy, Technical Status and Indoor environment study, a total of 1160 adults from 605 single-family houses answered a questionnaire on respiratory health. Building inspectors investigated the homes and measured temperature, air humidity, air exchange rate, and wood moisture content (in attic and crawl space). Moisture load was calculated as the difference between indoor and outdoor absolute humidity. Totally, 7.3% were smokers, 8.7% had doctor' diagnosed asthma, 11.2% current wheeze, and 9.5% current asthma symptoms. Totally, 50.3% had respiratory infections and 26.0% rhinitis. The mean air exchange rate was 0.36/h, and the mean moisture load 1.70 g/m 3 . Damp foundation (OR=1.79, 95% CI 1.16-2.78) was positively associated while floor constructions with crawl space (OR=0.49, 95% CI 0.29-0.84) was negatively associated with wheeze. Concrete slabs with overlying insulation (OR=2.21, 95% CI 1.24-3.92) and brick façade (OR=1.71, 95% CI 1.07-2.73) were associated with rhinitis. Moisture load was associated with respiratory infections (OR=1.21 per 1 g/m 3 , 95% CI 1.04-1.40) and rhinitis (OR=1.36 per 1 g/m 3 , 95% CI 1.02-1.83). Air exchange rate was associated with current asthma symptoms (OR=0.85 per 0.1/h, 95% CI 0.73-0.99). Living in homes with damp foundation, concrete slabs with overlying insulation, brick façade, low ventilation flow, and high moisture load are risk factors for asthma, rhinitis, and respiratory infections. © 2016 John Wiley & Sons A/S.

    In order to reduce the energy consumption of the building stock, a major trend is to drastically reduce the space-heating (SH) needs by improving the thermal performance of the envelope. In general, this measure is combined with efficient heating systems to minimize the delivered energy and greenhouse gas emissions. Nevertheless, these better systems are often more expensive so that the extra-investment could be hardly recovered for small-scale energy consumption. The main objective of the article is to show how equilibria between cost-effectiveness and environmental performance of heating systems are changed when small SH needs are considered (i.e. for passive and low-energy houses). The scope is limited to new single-family dwellings. Furthermore, the passive house standard provides means of simplifying the SH by using the ventilation air: the idea is that savings should counterbalance the extra-investment in super-insulation. In theory, a new global economic optimum is generated at the passive house level. The second objective of the work is to study which conditions could lead to this new optimum. Only a detached-house typology is investigated to address this last issue. Regarding methodology, all the investigations are done considering the Belgian context. Energy and environmental performance is evaluated using a method that complies with the EN-15603 and EN-15316 standards. - Highlights: ► Cost-benefit analysis is performed without incentives and is based on the Belgian market. ► Equilibria between cost-effectiveness and environmental performance of heating systems are changed for very low-energy houses. ► The space-heating simplification at the passive house level can hardly produce a new global economic optimum.

    Little information has been published in the literature regarding survival outcomes of patients with Ewing's sarcoma family tumors (ESFTs) of the spine. The purpose of this study is to explore factors that may affect the prognosis of patients with non-metastatic spinal ESFTs. A retrospective analysis of survival outcomes was performed in patients with non-metastatic spinal ESFTs. Univariate and multivariate analyses were employed to identify prognostic factors for recurrence and survival. Recurrence-free survival (RFS) and overall survival (OS) were defined as the date of surgery to the date of local relapse and death. Kaplan-Meier methods were applied to estimate RFS and OS. Log-rank test was used to analyze single factors for RFS and OS. Factors with p values ≤0.1 were subjected to multivariate analysis. A total of 63 patients with non-metastatic spinal ESFTs were included in this study. The mean follow-up period was 35.1 months (range 1-155). Postoperative recurrence was detected in 25 patients, and distant metastasis and death occurred in 22 and 36 patients respectively. The result of multivariate analysis suggested that age older than 25 years and neoadjuvant chemotherapy were favorable independent prognostic factors for RFS and OS. In addition, total en-bloc resection, postoperative chemotherapy, radiotherapy and non-distant metastasis were favorable independent prognostic factors for OS. Age older than 25 years and neoadjuvant chemotherapy are favorable prognostic factors for both RFS and OS. In addition, total en-bloc resection, postoperative chemotherapy, radiotherapy and non-distant metastasis are closely associated with favorable survival.

    Microorganisms are known to produce a range of volatile organic compounds, so-called microbial VOC (MVOC). Chamber studies where humans were exposed to MVOC addressed the acute effects of objective and/or subjective signs of mucosal irritation. However, the effect of MVOC on inhabitants due to household exposure is still unclear. The purpose of this epidemiological study was to measure indoor MVOC levels in single family homes and to evaluate the relationship between exposure to them and sick building syndrome (SBS). All inhabitants of the dwellings were given a self-administered questionnaire with standardized questions to assess their symptoms. Air samples were collected and the concentrations of eight selected compounds in indoor air were analyzed by gas chromatography/mass spectrometry - selective ion monitoring mode (GC/MS-SIM). The most frequently detected MVOC was 1-pentanol at a detection rate of 78.6% and geometric mean of 0.60 μg/m 3 . Among 620 participants, 120 (19.4%) reported one or more mucous symptoms; irritation of the eyes, nose, airway, or coughing every week (weekly symptoms), and 30 (4.8%) reported that the symptoms were home-related (home-related symptoms). Weekly symptoms were not associated with any of MVOC, whereas significant associations between home-related mucous symptoms and 1-octen-3-ol (per log 10 -unit: odds ratio (OR) 5.6, 95% confidence interval (CI): 2.1 to 14.8) and 2-pentanol (per log 10 -unit: OR 2.3, 95% CI: 1.0 to 4.9) were obtained after adjustment for gender, age, and smoking. Associations between home-related symptoms and 1-octen-3-ol remained after mutual adjustment. However, concentrations of the selected compounds in indoors were lower than the estimated safety level in animal studies. Thus, the statistically significant association between 1-octen-3-ol may be due to a direct effect of the compounds or the associations may be being associated with other offending compounds. Additional studies are needed to evaluate

    A randomized controlled trial was carried out to measure the impact of an intervention on ventilation, indoor air contaminants, and asthma symptoms of children. Eighty-three asthmatic children living in low-ventilated homes were followed over 2 years. Several environmental parameters were measured during the summer, fall, and winter. The children were randomized after Year 1 (43 Intervention; 40 Control). The intervention included the installation of either a Heat Recovery Ventilator (HRV) or Energy Recovery Ventilator (ERV). During the fall and winter seasons, there was a significant increase in the mean ventilation rate in the homes of the intervention group. A statistically significant reduction in mean formaldehyde, airborne mold spores, toluene, styrene, limonene, and α-pinene concentrations was observed in the intervention group. There was no significant group difference in change in the number of days with symptoms per 14 days. However, there was a significant decrease in the proportion of children who experienced any wheezing (≥1 episode) and those with ≥4 episodes in the 12-month period in the intervention group. This study indicates that improved ventilation reduces air contaminants and may prevent wheezing. Due to lack of power, a bigger study is needed. Positive findings from this study include the fact that, upon recruitment, most of the single family homes with asthmatic children were already equipped with a mechanical ventilation system and had relatively good indoor air quality. However, the 8-h indoor guideline for formaldehyde (50 μg/m3) was frequently exceeded and the ventilation rates were low in most of the homes, even those with a ventilation system. Both ERVs and HRVs were equally effective at increasing air exchange rates above 0.30 ACH and at preventing formaldehyde concentrations from exceeding the 50 μg/m3 guideline during the fall and winter seasons. Furthermore, the ERVs were effective at preventing excessively low relative

    Full Text Available The process of precarization is analysed in different manners in most literature concerning contemporary stakes of western welfare states. In comparison to other countries, Belgium has known a rather specific and delimited effect of the economic crisis from 2008, but certain groups face rather an ongoing effect of precarization on multiple and intertwined aspects. The aim of the article is to analyse the situation of precarity of single-parent families in the Brussels-Capital Region. The attention to that group is related to its higher risk of precarity and poverty. Furthermore it allows analysing the limits of public policies in the fight against poverty and precarity, that are clearly inadequate. Various options in terms of public policies and legal measures in the fight against poverty are discussed from three different angles of perspective: socioeconomic positions, social integration and the subjective experience (Dubet 1994. The tension between recognition and redistribution measures is central (Fraser 2011 in the argumentation for a balanced vision of policy measures to address single-parent poverty. La literatura científica sobre las apuestas contemporáneas de los estados de bienestar occidentales analiza de forma diferente el proceso de precarización. En comparación con otros países, Bélgica ha vivido desde 2008 un efecto de la crisis económica bastante específico y delimitado. Sin embargo, algunos grupos se enfrentan a un proceso de precarización continuo en numerosos aspectos, interrelacionados entre sí. El objetivo de este artículo es analizar la situación de precariedad de las familias monoparentales de la región de Bruselas capital. La atención a ese grupo está relacionada con su mayor riesgo de precariedad y pobreza. Además, permite analizar los límites de las políticas públicas en la lucha contra la pobreza y la precariedad, que son claramente insuficientes. Se analizan desde tres puntos de vista diversas

    Full Text Available Introduction: gastric cancer is the most frequent gastrointestinal malignancy in Mexico and the proportion of patients younger than 40 years is one of the highest reported in the world literature. Recently several families with familial diffuse gastric cancer have been identified at the National Institute of Medical Sciences and Nutrition. Germline mutations in the E-cadherin gene (CHD1 have been described that result in the development of diffuse hereditary gastric cancer in young patients. Methods: the complete coding sequence at exons 1 to 16 and the promoter region of CDH1 was amplified by polymerase chain reaction in peripheral blood samples of two patients with early onset familial diffuse gastric cancer. Results: no germline inactivating mutations of CHD1 were found on either patient. Single nucleotide polymorphisms -160 C→A were detected in the promoter region of CDH1 in both patients. Conclusions: the polymorphism -160 C→A theoretically confers an increased risk of developing diffuse gastric cancer. The relatives of these patients may an increased risk of gastric cancer among other tumors. There is presently not enough evidence to consider the -160 C→A polymorphism an etiologic factor of diffuse gastric cancer in these patients since the frequency and type of genetic alterations of CDH1 are largely unknown in the Mexican population. It will be necessary to conduct epidemiologic studies in the Mexican population to determine the influence that genetic alterations have on the genesis of diffuse gastric carcinoma.Introducción: el cáncer gástrico es la neoplasia más frecuente del tracto gastrointestinal en México y la proporción de pacientes menores de 40 años es una de las más altas reportadas en la literatura mundial.

    The Schulhof family, a tight cluster of small asteroids around the central main belt body (2384) Schulhof, belongs to a so far rare class of very young families (estimated ages less than 1 Myr). Characterization of these asteroid clusters may provide important insights into the physics of the catastrophic disruption of their parent body. The case of the Schulhof family has been up to now complicated by the existence of two proposed epochs of its origin. In this paper, we first use our own photometric observations, as well as archival data, to determine the rotation rate and spin axis orientation of the largest fragment (2384) Schulhof. Our data also allow us to better constrain the absolute magnitude of this asteroid, and thus also improve the determination of its geometric albedo. Next, using the up-to-date catalog of asteroid orbits, we perform a new search of smaller members in the Schulhof family, increasing their number by 50%. Finally, the available data are used to access Schulhof's family age anew. We now find that the younger of the previously proposed two ages of this family is not correct, resulting from a large orbital uncertainty of single-opposition members. Our new runs reveal a single age solution of about 800 kyr with a realistic uncertainty of 200 kyr.

    Full Text Available The paper presents the results of a study of the psychological characteristics of boys and girls from complete and incomplete families. In addition to the type of family, the authors consider the educational tactics of mothers. The combined effects of the type of family and educational tactics on psychological characteristics of the adolescent were investigated. Adolescence was chosen as a period, when on the one hand, a relatively stable personality structure is developed, and on the other hand, the importance of the immediate social environment is extremely high. For our study we selected the psychological characteristics, to the utmost revealing the reaction of children to their parents' divorce: the level of subjective control (degree of responsibility for their own lives, and the sovereignty of the psychological space (clearnesse of psychological boundaries. It is shown that the largest influence on the psychological characteristics of adolescents, regardless of the type of family, is rendered by hostility in maternal education. The dependence of psychological characteristics of maternal directiveness occurs only at high values ​​of such educational tactics that highlights the consistency of the obtained results with the classical

    Corbett, K

    2001-07-01

    Family stories lie at the heart of psychoanalytic developmental theory and psychoanalytic clinical technique, but whose family? Increasingly, lesbian and gay families, multiparent families, and single-parent families are relying on modern reproductive technologies to form families. The contemplation of these nontraditional families and the vicissitudes of contemporary reproduction lead to an unknowing of what families are, including the ways in which psychoanalysts configure the family within developmental theory. This article focuses on the stories that families tell in order to account for their formation--stories that include narratives about parental union, parental sexuality, and conception. The author addresses three constructs that inform family stories and that require rethinking in light of the category crises posed by and for the nontraditional family: (1) normative logic, (2) family reverie and the construction of a family romance, and (3) the primal scene. These constructs are examined in tandem with detailed clinical material taken from the psychotherapy of a seven-year-old boy and his two mothers.

    The Drosophila protein Turtle and the vertebrate proteins immunoglobulin superfamily (IgSF), member 9 (IGSF9/Dasm1) and IGSF9B are members of an evolutionarily ancient protein family. A bioinformatics analysis of the protein family revealed that invertebrates contain only a single IGSF9 family gene......, the longest isoforms of the proteins have the same general organization as the neural cell adhesion molecule family of cell adhesion molecule proteins, and like this family of proteins, IGSF9 family members are expressed in the nervous system. A review of the literature revealed that Drosophila Turtle...... facilitates homophilic cell adhesion. Moreover, IGSF9 family proteins have been implicated in the outgrowth and branching of neurites, axon guidance, synapse maturation, self-avoidance, and tiling. However, despite the few published studies on IGSF9 family proteins, reports on the functions of both Turtle...

    Full Text Available This study attempted to find a correlation between the trauma of family members of war and exile, and the characteristics of family functioning and lasted from 1992-1995. The term “family resilience” refers to the processes of adaptation and coping in the family as a functional unit. This paper presents a study of refugee families from Bosnia, who lived in refugee camps in Macedonia during the war of 1992- 1995. Data were obtained by interviews, observations, and a number of psychological instruments especially for children and parents, which measured the effects of psychological stress and family relationships. Based on the results obtained by quantitative and qualitative analysis, and application of theoretical models of systemic theory and family therapy, existence for four types of refugee families has been found and described, depending on the structure and the level of functionality.

  6. Summary of existing uncertainty methods

    International Nuclear Information System (INIS)

    Glaeser, Horst

    2013-01-01

    A summary of existing and most used uncertainty methods is presented, and the main features are compared. One of these methods is the order statistics method based on Wilks' formula. It is applied in safety research as well as in licensing. This method has been first proposed by GRS for use in deterministic safety analysis, and is now used by many organisations world-wide. Its advantage is that the number of potential uncertain input and output parameters is not limited to a small number. Such a limitation was necessary for the first demonstration of the Code Scaling Applicability Uncertainty Method (CSAU) by the United States Regulatory Commission (USNRC). They did not apply Wilks' formula in their statistical method propagating input uncertainties to obtain the uncertainty of a single output variable, like peak cladding temperature. A Phenomena Identification and Ranking Table (PIRT) was set up in order to limit the number of uncertain input parameters, and consequently, the number of calculations to be performed. Another purpose of such a PIRT process is to identify the most important physical phenomena which a computer code should be suitable to calculate. The validation of the code should be focused on the identified phenomena. Response surfaces are used in some applications replacing the computer code for performing a high number of calculations. The second well known uncertainty method is the Uncertainty Methodology Based on Accuracy Extrapolation (UMAE) and the follow-up method 'Code with the Capability of Internal Assessment of Uncertainty (CIAU)' developed by the University Pisa. Unlike the statistical approaches, the CIAU does compare experimental data with calculation results. It does not consider uncertain input parameters. Therefore, the CIAU is highly dependent on the experimental database. The accuracy gained from the comparison between experimental data and calculated results are extrapolated to obtain the uncertainty of the system code predictions

    This study evaluated the yield of ajmaline testing and assessed the occurrence of confounding responses in a large cohort of families with unexplained cardiac arrest (UCA) or sudden unexplained death (SUD). Ajmaline testing to diagnose Brugada syndrome (BrS) is routinely used in the evaluation of SUD and UCA, but its yield, limitations, and appropriate dosing have not been studied in a large cohort. We assessed ajmaline test response and genetic testing results in 637 individuals from 482 families who underwent ajmaline testing for SUD or UCA. Overall, 89 individuals (14%) from 88 families (18%) had a positive ajmaline test result. SCN5A mutations were identified in 9 of 86 ajmaline-positive cases (10%). SCN5A mutation carriers had positive test results at significantly lower ajmaline doses than noncarriers (0.75 [range: 0.64 to 0.98] mg/kg vs. 1.03 [range: 0.95 to 1.14] mg/kg, respectively; p genetic diagnosis accounting for UCA/SUD (5 cases) or noncosegregation of positive ajmaline response and arrhythmia (2 cases). The rate of confounding responses was significantly higher in positive ajmaline responses obtained at >1 mg/kg than in those obtained at ≤1 mg/kg (7 of 48 vs. 0 of 41 individuals; Fisher's exact test: p = 0.014). In line with previous, smaller studies, a positive ajmaline response was observed in a large proportion of UCA/SUD families. Importantly, our data emphasize the potential for confounding possibly false-positive ajmaline responses in this population, particularly at high doses, which could possibly lead to a misdiagnosis. Clinicians should consider all alternative causes in UCA/SUD and avoid ajmaline doses >1 mg/kg. Copyright © 2017 American College of Cardiology Foundation. Published by Elsevier Inc.

    Individuals with insulin resistance and type 2 diabetes have an impaired ability to switch appropriately between carbohydrate and fatty acid oxidation. However, whether this is a cause or consequence of insulin resistance is unclear, and the mechanism(s) involved in this response is not completely elucidated. Whole-body fat oxidation and transcriptional regulation of genes involved in lipid metabolism in skeletal muscle were measured after a prolonged fast and after consumption of either high-fat (76%) or high-carbohydrate (76%) meals in individuals with no family history of type 2 diabetes (control, n = 8) and in age- and fatness-matched individuals with a strong family history of type 2 diabetes (n = 9). Vastus lateralis muscle biopsies were performed before and 3 h after each meal. Insulin sensitivity and fasting measures of fat oxidation were not different between groups. However, subjects with a family history of type 2 diabetes had an impaired ability to increase fatty acid oxidation in response to the high-fat meal (P FAT)/CD36 (P fat meal in both groups, but it was not changed after the high-carbohydrate meal. In conclusion, an impaired ability to increase fatty acid oxidation precedes the development of insulin resistance in genetically susceptible individuals. PGC1alpha and FAT/CD36 are likely candidates in mediating this response.

    1995-03-01

    We have identified three mutations associated with transferase-deficiency galactosemia in a three-generation family including affected members in two generations and have modeled all three mutations in a yeast-expression system. A sequence of pedigree, biochemical, and molecular analyses of the galactose-1-phosphate uridyltransferase (GALT) enzyme and genetic locus in both affected and carrier individuals revealed three distinct base substitutions in this family, two (Q188R and S135L) that had been reported previously and one (V151A) that was novel. Biochemical analyses of red-blood-cell lysates from the relevant family members suggested that each of these mutations was associated with dramatic impairment of GALT activity in these cells. While this observation was consistent with our previous findings concerning the Q188R mutation expressed both in humans and in a yeast-model system, it was at odds with a report by Reichardt and colleagues, indicating that in their COS cell-expression system the S135L substitution behaved as a neutral polymorphism. To address this apparent paradox, as well as to investigate the functional significance of the newly identified V151A substitution, all three mutations were recreated by site-directed mutagenesis of the otherwise wild-type human GALT sequence and were expressed both individually and in the appropriate allelic combinations in a GALT-deficient strain of the yeast Saccharomyces cerevisiae. The results of these yeast-modeling studies were fully consistent with the patient data, leading us to conclude that, at least within the context of the cell types studied, in the homozygous state Q188R is a mutation that eliminates GALT activity, and S135L and V151A are both mutations that impair GALT activity to <6% of wild-type values. 22 refs., 5 figs.

    There is limited data regarding outcomes of Ewing's sarcoma family of tumors in adolescents and adults compared with the same tumors in childhood. The aim of the study was to analyze prognostic factors and treatment results in a cohort of adolescents and adults with non-metastatic skeletal Ewing's sarcoma family of tumors. From 1992-2008, 90 adolescents and adults with Ewing's sarcoma family of tumors of the bone were referred to our institution. Sixty-five (72%) non-metastatic patients with analyzable data and treated in our institution were retrospectively evaluated. All patients were treated with alternated chemotherapy regimens administered every 3 weeks. The local treatment modality was selected according to tumor and patient characteristics. The median age was 21 years (range, 13-50). Most patients (74%) were >17 years of age. Forty-six percent of the tumors were located in the extremities. Local therapy was surgery in 45 patients and radiotherapy alone in 19 patients. Twenty-one patients received preoperative and 13 patients postoperative radiotherapy. Median follow-up was 43 months (range, 7-167). The 5-year event-free and overall survival rates for all patients were 44% and 49%, respectively. On univariate survival analysis, event-free and overall survival were worse for patients >17 years of age, tumor size >8 cm in diameter, an axial location, positive surgical margins, and poor histopathological response (<90% necrosis). Age, tumor site and tumor size on event-free and overall survival remained significant on multivariate analysis. We identified age, tumor size, and tumor site as independent prognostic factors, in accord with the Western literature. These patients require novel treatment modalities.

    Temperature-induced packing polymorphism is observed for vitamin K 3 (menadione, 3-methyl-1,4-naphthoquinone, 1). Form 1a crystallizes at 300 K and 1b at 277 K both in the same space group P2 1/ c. Form 1b contains one molecule per asymmetric unit, performing anisotropy in g-factor viz. g z = 2.0082, g y = 2.0055 and g x = 2.0025, whereas form 1a contains two molecules in its asymmetric unit. Vitamin K 3 family members 2, [2-hydroxy vitamin K 3] and 3, [2-hydroxy-1-oximino vitamin K 3] also perform intrinsic neutral active naphthosemiquinone valence tautomers even in dark having spin concentrations due to hydrogen bonding and aromatic stacking interactions which are compared to vitamin K 3. The significant lateral C-H⋯O and O-H⋯π bifurcated or π-π ∗ interactions are discussed for molecular associations and radical formations. X-ray structure of 3 revealed π-π ∗ stack dimers as radicals signatured in EPR as triplet with five hyperfine splits [ Ā( 14N) = 11.9 G]. The centrosymmetric biradicals in 3 show diamagnetism at high temperature but below 10 K it shows paramagnetism with μeff as 0.19 B.M. Vitamin K 3 and its family members inhibit biological activities of acid phosphatase ( APase), which are proportional to their spin concentrations. This may relate to their probable anti-oncogenic candidature in future.

    After minimal sample preparation, two different HPLC methodologies, one based on a single gradient reversed-phase HPLC step, the other on multiple HPLC runs each optimised for specific components, were used to investigate the composition of flavonoids and phenolic acids in apple and tomato juices. The principal components in apple juice were identified as chlorogenic acid, phloridzin, caffeic acid and p-coumaric acid. Tomato juice was found to contain chlorogenic acid, caffeic acid, p-coumaric acid, naringenin and rutin. The quantitative estimates of the levels of these compounds, obtained with the two HPLC procedures, were very similar, demonstrating that either method can be used to analyse accurately the phenolic components of apple and tomato juices. Chlorogenic acid in tomato juice was the only component not fully resolved in the single run study and the multiple run analysis prior to enzyme treatment. The single run system of analysis is recommended for the initial investigation of plant phenolics and the multiple run approach for analyses where chromatographic resolution requires improvement.

    Full Text Available O presente artigo apresenta um estudo comparativo entre as crenças de agentes comunitários de saúde sobre possibilidades de resiliência em famílias monoparentais e de baixa renda e as estratégias de enfrentamento das adversidades que emergem nas histórias de vida destas famílias. Tomou-se como base a noção de resiliência aplicada à Psicologia, que se refere aos processos que explicam a superação de adversidades. Foram entrevistados quatro agentes comunitários de saúde e quatro famílias monoparentais. As estratégias metodológicas foram: entrevistas semi-estruturadas, histórias de vida, entrevista reflexiva e a análise dos dados através da grounded-theory. Os resultados revelaram crenças pessimistas dos agentes comunitários sobre o funcionamento das famílias pobres, em contraposição aos fatores indicativos de resiliência constatados nas histórias de vida destas famílias. Os resultados sinalizam para a necessidade de transformar e adequar as percepções dos agentes sociais acerca de grupos que vivem situação de pobreza.This article presents a comparative study on the health community agent's beliefs about the possibilities of resilience in low-income single-parent families and the coping strategies of these families in adverse situations that emerge from their life stories. The notion of resilience as applied in Psychology was taken as reference, which refers to the processes that explains how people overcome adversities. Four health agents and four single parent families were interviewed. The methodological strategies to guide the data analysis were: open interviews, life stories, reflexive interviews and grounded-theory. The results showed that the community agents hold pessimist beliefs about the poor families functioning in opposition to the elements that indicate resilience in these families' life stories. The results point to the need of transforming and adjusting the social agent's perceptions on groups who

    Family violence is a serious public health problem, the scale of which is seriously increasing in Morocco. Although it has existed for a long time, we ignore the real characteristics of this plague in our country; our work consisted in an epidemiological approach of family violence in Marrakech during 2006. After elaborating a questionnaire, which allows the study of the demographic and social profile of the families, the study of violence exercised in the family and the evaluation of the depression in the women, we led an inquiry amongst 265 women. Analysis of the results obtained has allowed us to underline the following characteristics: 16.6% of the women in our sample had been physically beaten; the young age is a risk factor; the age range most affected by violence is in women between the ages of 30 and 40 and which represent 39% of the battered women; domestic violence touches all the social, economic and cultural classes: in our study, 63% of the women having undergone violence were housewives, 25% were managers and 3% senior executives; family problems were the most important cause of violence in our study, representing 32.32%. Requests for money was the cause in 11.3% of the cases, and imposed sexual relations were found in 6.8% of the cases; alcoholism is an aggravating factor of family violence; 27.3% of the spouses who assaulted their wives were drunk; 52% of the assaulted women were victims of violence in childhood and 36% had been witness to their father's violence; in 63.6% of the cases of violence, the children were witnesses, and in 25% of the cases the children were victims of violence at the same time as their mothers; 50% of the women victims of violence did not react, while 38.6% left home, and 9.1 filed for divorce. Thirty-two percent of the assaulted woman had been traumatised by the aggression; the association of depression and violence was very high, 343% of the battered women in our study suffered from severe depression.

    The increasing number of new and renovated buildings with reduced heating requirements will soon make traditional District Heating (DH) systems uneconomic. To keep DH competitive in the future, the heat loss in DH networks needs to be reduced. One option is to reduce the supply temperature of DH...... as much as possible. This requires a review of the behaviour of the whole domestic hot water (DHW) supply system with focus on the user comfort and overall costs. This paper describes some practical approaches to the implementation of this Low Energy District Heating (LEDH) concept. It reports...... on the testing of the dynamic behaviour of an Instantaneous Heat Exchanger Unit(IHEU) designed for DHW heating and space heating in detached family houses supplied by LEDH ensuring an entry-to-substation temperature of 51 °C. We measured the time it takes for the IHEU to produce DHW with a temperature of 42 °C...

    The HERV-W family of human endogenous retroviruses represents a group of numerous sequences that show close similarity in genetic composition. It has been documented that some members of HERV-W-derived expression products are supposed to play significant role in humans' pathology, such as multiple sclerosis or schizophrenia. Other members of the family are necessary to orchestrate physiological processes (eg, ERVWE1 coding syncytin-1 that is engaged in syncytiotrophoblast formation). Therefore, an assay that would allow the recognition of particular form of HERV-W members is highly desirable. A peptide nucleic acid (PNA)-mediated technique for the discrimination between multiple sclerosis-associated retrovirus and ERVWE1 sequence has been developed. The assay uses a PNA probe that, being fully complementary to the ERVWE1 but not to multiple sclerosis-associated retrovirus (MSRV) template, shows high selective potential. Single-stranded DNA binding protein facilitates the PNA-mediated, sequence-specific formation of strand invasion complex and, consequently, local DNA unwinding. The target DNA may be then excluded from further analysis in any downstream process such as single-stranded DNA-specific exonuclease action. Finally, the reaction conditions have been optimized, and several PNA probes that are targeted toward distinct loci along whole HERV-W env sequences have been evaluated. We believe that PNA/single-stranded DNA binding protein-based application has the potential to selectively discriminate particular HERV-W molecules as they are at least suspected to play pathogenic role in a broad range of medical conditions, from psycho-neurologic disorders (multiple sclerosis and schizophrenia) and cancers (breast cancer) to that of an auto-immunologic background (psoriasis and lupus erythematosus).

    The article describes general principles and basis of evaluation of existing railway bridges based on the concept of load-carrying capacity determination. Compared to the design of a new bridge, the modified reliability level for existing bridges evaluation should be considered due to implementation of the additional data related to bridge condition and behaviour obtained from regular inspections. Based on those data respecting the bridge remaining lifetime, a modification of partial safety factors for actions and materials could be respected in the bridge evaluation process. A great attention is also paid to the specific problems of determination of load-caring capacity of steel railway bridges in service. Recommendation for global analysis and methodology for existing steel bridge superstructure load-carrying capacity determination are described too.

    A single-step multiplex PCR (here referred to as a duplex PCR) has been developed for simultaneous detection and diagnosis of Fasciola hepatica and F. gigantica. These species overlap in distribution in many countries of North and East Africa and Central and Southeast Asia and are similar in egg morphology, making identification from fecal samples difficult. Based on a comparative alignment of mitochondrial DNA (mtDNA) spanning the region of cox1-trnT-rrnL, two species-specific forward primers were designed, FHF (for F. hepatica) and FGF (for F. gigantica), and a single reverse primer, FHGR (common for both species). Conventional PCR followed by sequencing was applied using species-specific primer pairs to verify the specificity of primers and the identity of Fasciola DNA templates. Duplex PCR (using three primers) was used for testing with the DNA extracted from adult worms, miracidia, and eggs, producing amplicons of 1,031 bp for F. hepatica and 615 bp for F. gigantica. The duplex PCR failed to amplify from DNA of other common liver and intestinal trematodes, including two opisthorchiids, three heterophyids, an echinostomid, another fasciolid, and a taeniid cestode. The sensitivity assay showed that the duplex PCR limit of detection for each Fasciola species was between 0.012 ng and 0.006 ng DNA. Evaluation using DNA templates from 32 Fasciola samples (28 adults and 4 eggs) and from 25 field-collected stools of ruminants and humans revealed specific bands of the correct size and the presence of Fasciola species. This novel mtDNA duplex PCR is a sensitive and fast tool for accurate identification of Fasciola species in areas of distributional and zonal overlap. PMID:22692744

  10. Magneto-structural correlations in a family of Fe(II)Re(IV)(CN)2 single-chain magnets: density functional theory and ab initio calculations.

    Until now, the expressions of the anisotropic energy barriers Δξ and ΔA, using the uniaxial magnetic anisotropy D, the intrachain coupling strength J, and the high-spin ground state S for single-chain magnets (SCMs) in the intermediate region between the Ising and the Heisenberg limits, were unknown. To explore this relationship, we used density functional theory and ab initio methods to obtain expressions of Δξ and ΔA in terms of D, J, and S of six R4Fe(II)-Re(IV)Cl4(CN)2 (R = diethylformamide (1), dibutylformamide (2), dimethylformamide (3), dimethylbutyramide (4), dimethylpropionamide (5), and diethylacetamide (6)) SCMs in the intermediate region. The ΔA value for compounds 1-3 was very similar to the magnetic anisotropic energy of a single Fe(II), while the value of Δξ was predicted using the exchange interaction of Fe(II) with the neighboring Re(IV), which could be expressed as 2JSReSFe. Similar to compounds 1-3, the anisotropy energy barrier ΔA of compounds 4 and 5 was also equal to (Di - Ei)SFe(2), but the correlation energy Δξ was closely equal to 2JSReSFe(cos 98.4 - cos 180) due to the reversal of the spins on the opposite Fe(II). For compound 6, one unit cell of Re(IV)Fe(II) was regarded as a domain wall since it had two different Re(IV)-Fe(II) couplings. Thus, the Δξ of compound 6 was expressed as 4J″SRe1Fe1SRe2Fe2, where J″ was the coupling constant of the neighboring unit cells of Re1Fe1 and Re2Fe2, and ΔA was equal to the anisotropic energy barrier of one domain wall given by DRe1Fe1(S(2)Re1Fe1 - 1/4).

  11. The EXIST Mission Concept Study

    EXIST is a mission designed to find and study black holes (BHs) over a wide range of environments and masses, including: 1) BHs accreting from binary companions or dense molecular clouds throughout our Galaxy and the Local Group, 2) supermassive black holes (SMBHs) lying dormant in galaxies that reveal their existence by disrupting passing stars, and 3) SMBHs that are hidden from our view at lower energies due to obscuration by the gas that they accrete. 4) the birth of stellar mass BHs which is accompanied by long cosmic gamma-ray bursts (GRBs) which are seen several times a day and may be associated with the earliest stars to form in the Universe. EXIST will provide an order of magnitude increase in sensitivity and angular resolution as well as greater spectral resolution and bandwidth compared with earlier hard X-ray survey telescopes. With an onboard optical-infra red (IR) telescope, EXIST will measure the spectra and redshifts of GRBs and their utility as cosmological probes of the highest z universe and epoch of reionization. The mission would retain its primary goal of being the Black Hole Finder Probe in the Beyond Einstein Program. However, the new design for EXIST proposed to be studied here represents a significant advance from its previous incarnation as presented to BEPAC. The mission is now less than half the total mass, would be launched on the smallest EELV available (Atlas V-401) for a Medium Class mission, and most importantly includes a two-telescope complement that is ideally suited for the study of both obscured and very distant BHs. EXIST retains its very wide field hard X-ray imaging High Energy Telescope (HET) as the primary instrument, now with improved angular and spectral resolution, and in a more compact payload that allows occasional rapid slews for immediate optical/IR imaging and spectra of GRBs and AGN as well as enhanced hard X-ray spectra and timing with pointed observations. The mission would conduct a 2 year full sky survey in

  16. 2D DIGE Does Not Reveal all: A Scotopic Report Suggests Differential Expression of a Single "Calponin Family Member" Protein for Tetany of Sphincters!

    Science.gov (United States)

    Chaudhury, Arun

    2015-01-01

    Using 2D differential gel electrophoresis (DIGE) and mass spectrometry (MS), a recent report by Rattan and Ali (2015) compared proteome expression between tonically contracted sphincteric smooth muscles of the internal anal sphincter (IAS), in comparison to the adjacent rectum [rectal smooth muscles (RSM)] that contracts in a phasic fashion. The study showed the differential expression of a single 23 kDa protein SM22, which was 1.87 fold, overexpressed in RSM in comparison to IAS. Earlier studies have shown differences in expression of different proteins like Rho-associated protein kinase II, myosin light chain kinase, myosin phosphatase, and protein kinase C between IAS and RSM. The currently employed methods, despite its high-throughput potential, failed to identify these well-characterized differences between phasic and tonic muscles. This calls into question the fidelity and validatory potential of the otherwise powerful technology of 2D DIGE/MS. These discrepancies, when redressed in future studies, will evolve this recent report as an important baseline study of "sphincter proteome." Proteomics techniques are currently underutilized in examining pathophysiology of hypertensive/hypotensive disorders involving gastrointestinal sphincters, including achalasia, gastroesophageal reflux disease (GERD), spastic pylorus, seen during diabetes or chronic chemotherapy, intestinal pseudo-obstruction, and recto-anal incontinence. Global proteome mapping may provide instant snapshot of the complete repertoire of differential proteins, thus expediting to identify the molecular pathology of gastrointestinal motility disorders currently labeled "idiopathic" and facilitating practice of precision medicine.

    Structure in the Uranian ring system as observed in recent occultations may contain indirect evidence for the existence of undiscovered satellites. Using the Alfven and Arrhenius (1975, 1976) scenario for the formation of planetary systems, the orbital radii of up to nine hypothetical satellites interior to Miranda are computed. These calculations should provide interesting comparisons when the results from the Voyager 2 encounter with Uranus are made public. 15 refs., 1 fig., 1 tab

  2. Using the Rasch Measurement Model in Psychometric Analysis of the Family Effectiveness Measure

    Background Valid assessment of family functioning can play a vital role in optimizing client outcomes. Because family functioning is influenced by family structure, socioeconomic context, and culture, existing measures of family functioning--primarily developed with nuclear, middle class European American families--may not be valid assessments of families in diverse populations. The Family Effectiveness Measure was developed to address this limitation. Objectives To test the Family Effectiveness Measure with data from a primarily low-income African American convenience sample, using the Rasch measurement model. Method A sample of 607 adult women completed the measure. Rasch analysis was used to assess unidimensionality, response category functioning, item fit, person reliability, differential item functioning by race and parental status, and item hierarchy. Criterion-related validity was tested using correlations with five other variables related to family functioning. Results The Family Effectiveness Measure measures two separate constructs: The effective family functioning construct was a psychometrically sound measure of the target construct that was more efficient due to the deletion of 22 items. The ineffective family functioning construct consisted of 16 of those deleted items but was not as strong psychometrically. Items in both constructs evidenced no differential item functioning by race. Criterion-related validity was supported for both. Discussion In contrast to the prevailing conceptualization that family functioning is a single construct, assessed by positively and negatively worded items, use of the Rasch analysis suggested the existence of two constructs. While the effective family functioning is a strong and efficient measure of family functioning, the ineffective family functioning will require additional item development and psychometric testing.

    This draft final report for the Swiss Federal Office of Energy (SFOE) presents the results obtained from measurements made in eight single-family homes built to the Swiss 'Minergie' standard. The project served to validate partly simplified simulations concerning the summertime thermal behaviour of low energy consumption buildings built of wood. The eight various 'Minergie' houses are described, as is the measurement concept chosen. The results obtained and the conclusions drawn are presented in detail and discussed, as is the implementation of measures derived from the project. Heat storage effects in the various building components are discussed. The results of the measurements are compared with the theoretical values obtained from calculations. Recommendations are presented. The report is augmented with a comprehensive appendix which includes the detailed measurement results for the buildings examined.

  4. Aircraft family design using enhanced collaborative optimization

    Roth, Brian Douglas

    Significant progress has been made toward the development of multidisciplinary design optimization (MDO) methods that are well-suited to practical large-scale design problems. However, opportunities exist for further progress. This thesis describes the development of enhanced collaborative optimization (ECO), a new decomposition-based MDO method. To support the development effort, the thesis offers a detailed comparison of two existing MDO methods: collaborative optimization (CO) and analytical target cascading (ATC). This aids in clarifying their function and capabilities, and it provides inspiration for the development of ECO. The ECO method offers several significant contributions. First, it enhances communication between disciplinary design teams while retaining the low-order coupling between them. Second, it provides disciplinary design teams with more authority over the design process. Third, it resolves several troubling computational inefficiencies that are associated with CO. As a result, ECO provides significant computational savings (relative to CO) for the test cases and practical design problems described in this thesis. New aircraft development projects seldom focus on a single set of mission requirements. Rather, a family of aircraft is designed, with each family member tailored to a different set of requirements. This thesis illustrates the application of decomposition-based MDO methods to aircraft family design. This represents a new application area, since MDO methods have traditionally been applied to multidisciplinary problems. ECO offers aircraft family design the same benefits that it affords to multidisciplinary design problems. Namely, it simplifies analysis integration, it provides a means to manage problem complexity, and it enables concurrent design of all family members. In support of aircraft family design, this thesis introduces a new wing structural model with sufficient fidelity to capture the tradeoffs associated with component

    The aim of our study was to investigate the association of five single nucleotide polymorphisms in interleukin-1 (IL-1) gene with susceptibility to systemic sclerosis (SSc) in a Chinese population. A total of 58 SSc patients and 113 healthy controls were enrolled. TaqMan allele discrimination assay was performed to detect the genotyping of IL-1A -889C/T (rs1800587), IL-1B -511C/T (rs16944), IL-18 -607C/A (rs1946518), IL-18 -137G/C (rs187238) and IL-33 rs7044343. The association between these SNPs and SSc risk was analyzed. Furthermore, a meta-analysis of relevant studies on the association of IL-1A -889C/T (rs1800587) and IL-1B -511C/T (rs16944) with the susceptibility to SSc was performed. Through the genotyping, significant associations for SSc were found for: IL-1A -889C/T genotype frequencies (P = 0.000), dominant model (P = 0.000), recessive model (P = 0.001) and allele T frequency (P = 0.000). Among SSc patients, dyspnea was significantly associated with IL-18 -607C/A genotype frequency and IL-33 rs7044343 allele frequency (P = 0.037, P = 0.042, respectively). In addition, elevated erythrocyte sedimentation rate was significantly associated with IL-18 -137G/C (rs187238) genotype and allele frequency (P = 0.019, P = 0.006, respectively). While meta-analysis showed there was no significant association between IL-1A -889C/T polymorphism and SSc, for IL-1B -511C/T (rs16944), significant associations were found in the comparison of allele C versus T (OR 1.267, 95 % CI 1.016-1.580) by combined different outcomes. Results showed that IL-1A -889C/T (rs1800587) was associated with SSc susceptibility in the Chinese population. However, this association was not supported by a meta-analysis of all relevant studies. Further investigations are required to verify our findings.

  6. Quantum logics with existence property

    Schindler, C.

    1991-01-01

    A quantum logic (σ-orthocomplete orthomodular poset L with a convex, unital, and separating set Δ of states) is said to have the existence property if the expectation functionals on lin(Δ) associated with the bounded observables of L form a vector space. Classical quantum logics as well as the Hilbert space logics of traditional quantum mechanics have this property. The author shows that, if a quantum logic satisfies certain conditions in addition to having property E, then the number of its blocks (maximal classical subsystems) must either be one (classical logics) or uncountable (as in Hilbert space logics)

  7. Another way to teach family: family nursing game

    2014-10-01

    Full Text Available Current paper describes the application of an innovative strategy to teach family, within a hospital context, by sensitizing nurses on the family subject through the use of a game. Given the hospitalization of a relative, the family faces changes in its dynamics caused by the crisis it is exposed to. It is the relevance for including the family within the care process. Since nurses are expected to assume a key role for which they need specific competence to intervene in families when experiencing an eventual crisis. The in-service education becomes a strategy of generating new skills and enhances human capital to improve the quality of nursing care. Considering the importance of including family in the care context, a playful tool called Family Nursing Game has been invented for teaching the family, especially by passing a model of family intervention. The strategy is based on the belief of the existence of relationship between game and learning.

    2012-01-01

    Hypersexual Disorder has been proposed as a new psychiatric disorder for DSM-V, characterized by an increased frequency and intensity of sexually motivated fantasies, arousal, urges, and enacted behavior in association with an impulsivity component. Excessive appetitive and consummatory behaviors, including hypersexuality, can become a non-chemical addiction. Sexual addiction afflicts people having paraphilic or nonparaphilic behaviors associated with progressive risk-taking sexual behaviors, escalation or progression of sexual behaviors (tolerance), loss of control and significant adverse psychosocial consequences, such as unplanned pregnancy, pair-bond dysfunction, marital separation, financial problems and sexually transmitted diseases including HIV. The most common behaviors involved in sexual addiction are fantasy sex, compulsive masturbation, pornography, cybersex, voyeuristic sex, anonymous sex and multiple sexual partners. These behaviors are intended to reduce anxiety and other dysphoric affects (e.g., shame and depression). Axis I psychiatric diagnosis, especially mood disorders, psychoactive substance abuse disorders and attention deficit hyperactivity disorders, are common comorbid disorders with sexual addiction. There are significant gaps in the current scientific knowledge base regarding the clinical course, development risk factors and family history and data on women with sexual addiction are lacking.

    The results of investigation of cold nuclear fusion on palladium are given both for electrolysis of heavy water D 2 O and mixture D 2 O + H 2 O) (1:1) and for palladium saturation with gaseous deuterium. The possibility of existance of this phenomenon was examined by detection of neutrons and gamma quanta from reactions: d + d → 3 He + n + 3.27 MeV, p + d → 3 He + γ + 5.5 MeV. Besides these reactions were identified by measuring the characteristic X radiation of palladium due to effect of charged products 3 He, p, t. The upper limits of the intensities of hypothetical sources of neutrons and gamma quanta at the 95% confidence level were obtained to be Q n ≤ 2x10 -2 n/sxcm 3 Pd, Q γ ≤ 2x10 -3 γ/sxcm 3 Pd. 2 refs.; 4 figs.; 2 tabs

    2014-01-01

    One of the least studied universal deformations of incompressible nonlinear elasticity, namely the straightening of a sector of a circular cylinder into a rectangular block, is revisited here and, in particular, issues of existence and stability are addressed. Particular attention is paid to the system of forces required to sustain the large static deformation, including by the application of end couples. The influence of geometric parameters and constitutive models on the appearance of wrinkles on the compressed face of the block is also studied. Different numerical methods for solving the incremental stability problem are compared and it is found that the impedance matrix method, based on the resolution of a matrix Riccati differential equation, is the more precise.

    There exists a discrepancy between calculated destruction rates of grains in the interstellar medium and postulated sources of new grains. This problem was examined by modelling the global life cycle of grains in the galaxy. The model includes: grain destruction due to supernovae shock waves; grain injection from cool stars, planetary nebulae, star formation, novae, and supernovae; grain growth by accretion in dark clouds; and a mixing scheme between phases of the interstellar medium. Grain growth in molecular clouds is considered as a mechanism or increasing the formation rate. To decrease the shock destruction rate, several new physical processes, such as partial vaporization effects in grain-grain collisions, breakdown of the small Larmor radius approximation for betatron acceleration, and relaxation of the steady-state shock assumption are included

Los resultados sugieren que las configuraciones familiares investigadas no afectan, necesariamente, los comportamientos y las prácticas educativas maternas, ni mucho menos los comportamientos infantiles.Eventual differences in maternal behavior, childrearing practices and children’s behaviors in single-mother and two-parent families are analyzed. Fourteen families, 7 constituted by single mothers (mother and child and 7 by married mothers (mother, father and child, selected in hospitals and health units of Porto Alegre RS Brazil, participated in the study. The families were matched according to age, education and socioeconomic level. Using a protocol with several categories an observation session of the family at lunchtime in the participants’ home, when the children were 30-36 months old, was used to examine the maternal behavior and childrearing practices, as well as the children’s behaviors. Mann-Whitney test indicated no significant differences between single and married mothers for the categories examined. Results suggest that the family structure investigated do not necessarily affect maternal behaviors, childrearing practices and children’s behaviors.

    The acronym IDEALS summarizes family physicians' obligations when violence is suspected: to identify family violence; document injuries; educate families and ensure safety for victims; access resources and coordinate care; co-operate in the legal process; and provide support for families. Failure to respond reflects personal and professional experience and attitudes, fear of legal involvement, and lack of knowledge. Risks of intervention include physician burnout, physician overfunctioning, escalation of violence, and family disruption. PMID:21228987

  1. Axions from chiral family symmetry

    International Nuclear Information System (INIS)

    Chang, D.; Pal, P.B.; Maryland Univ., College Park; Senjanovic, G.

    1985-01-01

    We investigate the possibility that family symmetry, Gsub(F), is spontaneously broken chiral global symmetry. We classify the interesting cases when family symmetry can result in an automatic Peccei-Quinn symmetry U(1)sub(PQ) and thus provide a solution to the strong CP problem. The result disfavors having two or four families. For more than four families, U(1)sub(PQ) is in general automatic. In the case of three families, a unique Higgs sector allows U(1)sub(PQ) in the simplest case of Gsub(F)=[SU(3)] 3 . Cosmological consideration also puts strong constraint on the number of families. For Gsub(F)=[SU(N)] 3 cosmology singles out the three-family (N=3) case as a unique solution if there are three light neutrinos. Possible implication of decoupling theorem as applied to family symmetry breaking is also discussed. (orig.)

    This report made for the Swiss Federal Office of Energy (SFOE) presents the results of a study made at the University of Applied Science in Lucerne, Switzerland, on the improvements obtained as a result of the refurbishment of a single-family home in Huenenberg, Switzerland. The house, which was originally built in the 1960s, was refurbished in 1999 and well insulated. Its oil-fired heating system was replaced in 2000 with a wood-fired oven. The study presents the results of measurements made on the building concerning energy consumption and air-tightness etc., as well as on the efficiency of various components of the heating system (wood-fired oven, warm-air distribution system, heat recovery etc.). Weaknesses in the system that were thus discovered are listed and discussed. The increased fuel requirements caused by inefficiencies, non-appropriate user behaviour and the insufficient air-tightness of the building shell are quantified. General recommendations are made on the use of wood-fired ovens with warm-air heat distribution, in particular with respect to the insulation and air-tightness characteristics of the buildings.

    Non destructive testing are determined to be correlated with resistance to compression and flexion of elements belonging to prefabricated system of columns and floor tiles for single family homes of a level. The characteristics of the non destructive testing are described, such as: measurer of permeability, Schmidt sclerometer, determination of wave velocity by ultrasound and metal detector. The columns and floor tiles are elaborated with 2 mixtures of different resistances at 28 days. The first more than 30 MPa and the second less than 25 MPa are sampled together with the control cylinders necessary to obtain the actual resistance according to ASTM C39. Last resistance testings to compression and Schmidt sclerometer are realized to control cylinders to 1, 2, and 4 weeks after being cast. Non destructive testings (permeability meter Torrent, Schmidt sclerometer and determination of wave velocity by ultrasound) are performed in columns and floor tiles to 1, 2, and 4 weeks after being cast. Last resistance testings to flexion is obtained by means of destructive tests of the columns and floor tiles sampled. The correlation of the data obtained is determined to derive values of compression resistance from non destructive testing [es

    This report provides technical documentation for a software package called PEAR (Program for Energy Analysis of Residences) developed by LBL. PEAR offers an easy-to-use and accurate method of estimating the energy savings associated with various energy conservation measures used in site-built, single-family homes. This program was designed for use by non-technical groups such as home builders, home buyers or others in the buildings industry, and developed as an integral part of a set of voluntary guidelines entitled Affordable Housing Through Energy Conservation: A Guide to Designing and Constructing Energy Efficient Homes. These guidelines provide a method for selecting and evaluating cost-effective energy conservation measures based on the energy savings estimated by PEAR. This work is part of a Department of Energy program aimed at conducting research that will improve the energy efficiency of the nation's stock of conventionally-built and manufactured homes, and presenting the results to the public in a simplified format.

    The study of the family in the Caribbean originated with European scholars who assumed the universality of the patriarchal nuclear family and the primacy of this structure to the healthy functioning of society. Matrifocal Caribbean families thus were seen as chaotic and disorganized and inadequate to perform the essential tasks of the social system. This article provides a more current discussion of the Jamaican family. It argues that its structure is the result of the agency and adaptation of its members and not the root cause of the increasing marginalization of peoples in the developing world. The article focuses on families living in poverty and how the family structure supports essential family functions, adaptations, and survival.

    There has been considerable debate recently over the ages of the Hirayama families, and in particular if some of the families are very oung(u) It is a straightforward task to estimate the characteristic time of a collision between a body of a given diameter, d_o, by another body of diameter greater of equal to d_1. What is less straightforward is to estimate the critical diameter ratio, d_1/d_o, above which catastrophic disruption occurs, from which one could infer probable ages of the Hirayama families, by knowing the diameter of the parent body, d_o. One can gain some insight into the probable value of d_1/d_o, and of the likely ages of existing families, from the plot below. I have computed the characteristic time between collisions in the asteroid belt of a size ratio greater of equal to d_1/d_o, for 4 sizes of target asteroids, d_o.

  10. Functional Coverage of the Human Genome by Existing Structures, Structural Genomics Targets, and Homology Models.

    Directory of Open Access Journals (Sweden)

    2005-08-01

    Full Text Available The bias in protein structure and function space resulting from experimental limitations and targeting of particular functional classes of proteins by structural biologists has long been recognized, but never continuously quantified. Using the Enzyme Commission and the Gene Ontology classifications as a reference frame, and integrating structure data from the Protein Data Bank (PDB, target sequences from the structural genomics projects, structure homology derived from the SUPERFAMILY database, and genome annotations from Ensembl and NCBI, we provide a quantified view, both at the domain and whole-protein levels, of the current and projected coverage of protein structure and function space relative to the human genome. Protein structures currently provide at least one domain that covers 37% of the functional classes identified in the genome; whole structure coverage exists for 25% of the genome. If all the structural genomics targets were solved (twice the current number of structures in the PDB, it is estimated that structures of one domain would cover 69% of the functional classes identified and complete structure coverage would be 44%. Homology models from existing experimental structures extend the 37% coverage to 56% of the genome as single domains and 25% to 31% for complete structures. Coverage from homology models is not evenly distributed by protein family, reflecting differing degrees of sequence and structure divergence within families. While these data provide coverage, conversely, they also systematically highlight functional classes of proteins for which structures should be determined. Current key functional families without structure representation are highlighted here; updated information on the "most wanted list" that should be solved is available on a weekly basis from http://function.rcsb.org:8080/pdb/function_distribution/index.html.

    Full Text Available The demographic picture of Serbia over the last few decades has featured a negative trend, particularly fueled by the negative aspects of the transition process and adjustment to the new models of life functioning, and therefore the harmonization of family relationships is seriously undermined by the increased number of divorces, single-parent families and delayed parenthood. The research has confirmed that the parents opted for a larger number of children under the changed circumstances should relate to the government to take greater responsibility in this area. Programs do not necessarily have to be of material nature. They may include a variety of content-creative measures aimed at increasing the birth rate and the quality of family life by activating various discussions in the local community. National measures that would contribute to a harmonious family life are associated with an increased level of security, extended work of preschool institutions in order to harmonize work and family life and the introduction of discounts on equipment and clothing for the preschool children. In addition to reproductive functions, other functions of the family are: psychological, educational and socializing over the last decade (particularly after the introduction of compulsory pre-school program, which has led to the transformation of active strategies of the state and legislation in this regard and acceptance of the principle of lifelong learning in which preschool foundation plays a crucial role in the adaptation of compulsory education by providing equal starting conditions for all children. The existence of new forms of institutions such as family centers with a differentiated system of services (consulting, information, educational should compensate deficiencies of the existing system only on the basis of social protection embodied in the social welfare centers, which are available mostly in cases of pre-existing problems.

    Full Text Available The economic, cultural, and social transformation, growth of women's economic strength as well as the level of their education, and development of ideas of equal rights of women and men on the labour market and in social life cause changes in gender relation in the family. Poles more and more often declare and support egalitarian family, and a new model of a family appears among existing ones – dual-career family.The main aim of the article is to consider the sources of its rise, description of gender positions in marital relation, the division of tasks and responsibilities, possible dilemmas and conflicts, but also emotional, intellectual and social advantages. The analysis were put into context of changes in defining and describing family, and also in context of different family discourses. One of them was underlined the most – egalitarian one as the most approximate to the way of defining and understanding dual-career family model.

  15. Four RNA families with functional transient structures.

    Zhu, Jing Yun A; Meyer, Irmtraud M

    2015-01-01

    Protein-coding and non-coding RNA transcripts perform a wide variety of cellular functions in diverse organisms. Several of their functional roles are expressed and modulated via RNA structure. A given transcript, however, can have more than a single functional RNA structure throughout its life, a fact which has been previously overlooked. Transient RNA structures, for example, are only present during specific time intervals and cellular conditions. We here introduce four RNA families with transient RNA structures that play distinct and diverse functional roles. Moreover, we show that these transient RNA structures are structurally well-defined and evolutionarily conserved. Since Rfam annotates one structure for each family, there is either no annotation for these transient structures or no such family. Thus, our alignments either significantly update and extend the existing Rfam families or introduce a new RNA family to Rfam. For each of the four RNA families, we compile a multiple-sequence alignment based on experimentally verified transient and dominant (dominant in terms of either the thermodynamic stability and/or attention received so far) RNA secondary structures using a combination of automated search via covariance model and manual curation. The first alignment is the Trp operon leader which regulates the operon transcription in response to tryptophan abundance through alternative structures. The second alignment is the HDV ribozyme which we extend to the 5' flanking sequence. This flanking sequence is involved in the regulation of the transcript's self-cleavage activity. The third alignment is the 5' UTR of the maturation protein from Levivirus which contains a transient structure that temporarily postpones the formation of the final inhibitory structure to allow translation of maturation protein. The fourth and last alignment is the SAM riboswitch which regulates the downstream gene expression by assuming alternative structures upon binding of SAM. All

    Washington State has been developing plans and procedures for responding to nuclear accidents since the early 1970s. A key part of this process has been formulating a method for calculating ingestion pathway concentration guides (CGs). Such a method must be both technically sound and easy to use. This process has been slow and frustrating. However, much technical headway has been made in recent years, and hopefully the experience of the State of Washington will provide useful insight to problems with the existing guidance. Several recommendations are offered on ways to deal with these problems. In January 1986, the state held an ingestion pathway exercise which required the determination of allowed concentrations of isotopes for various foods, based upon reactor source term and field data. Objectives of the exercise were not met because of the complexity of the necessary calculations. A major problem was that the allowed concentrations had to be computed for each isotope and each food group, given assumptions on the average diet. To solve problems identified during that exercise, Washington developed, by March 1986, partitioned CGs. These CGs apportioned doses from each food group for an assumed mix of radionuclides expected to result from a reactor accident. This effort was therefore in place just in time for actual use during the Chernobyl fallout episode in May 1986. This technique was refined and described in a later report and presented at the 1987 annual meeting of the Health Physics Society. Realizing the technical weaknesses which still existed and a need to simplify the numbers for decision makers, Washington State has been developing computer methods to quickly calculate, from an accident specific relative mix of isotopes, CGs which allow a single radionuclide concentration for all food groups. This latest approach allows constant CGs for different periods of time following the accident, instead of peak CGs, which are good only for a short time after the

  18. Family intervention for schizophrenia.

    It has been showed that people with schizophrenia from families that express high levels of criticism, hostility, or over involvement, have more frequent relapses than people with similar problems from families that tend to be less expressive of their emotions. Psychosocial interventions designed to reduce these levels of expressed emotions within families now exist for mental health workers. These interventions are proposed as adjuncts rather than alternatives to drug treatments, and their main purpose is to decrease the stress within the family and also the rate of relapse. To estimate the effects of family psychosocial interventions in community settings for the care of those with schizophrenia or schizophrenia-like conditions compared to standard care. Electronic searches of the Cochrane Library (Issue 2, 1998), the Cochrane Schizophrenia Group's Register (June 1998), EMBASE (1981-1995) and MEDLINE (1966-1995) were undertaken and supplemented with reference searching of the identified literature. Randomised or quasi-randomised studies were selected if they focused on families of people with schizophrenia or schizoaffective disorder and compared community-orientated family-based psychosocial intervention of more than five sessions to standard care. Data were reliably extracted, and, where appropriate and possible, summated. Peto odds ratios (OR), their 95% confidence intervals (CI) and number needed to treat (NNT) were estimated. The reviewers assume that people who died or dropped out had no improvement and tested the sensitivity of the final results to this assumption. Family intervention may decrease the frequency of relapse (one year OR 0.57 CI 0.4-0.8, NNT 6.5 CI 4-14). The trend over time of this main finding is towards the null and some small but negative studies may not have been identified by the search. Family intervention may decrease hospitalisation and encourage compliance with medication but data are few and equivocal. Family intervention does not

    First members of a new family of heterometallic Mn/Ni complexes [Mn(2)Ni(3)X(2)L(4)(LH)(2)(H(2)O)(2)] (X = Cl: 1; X = Br: 2) with the new ligand 2-{3-(2-hydroxyphenyl)-1H-pyrazol-1-yl}ethanol (H(2)L) have been synthesized, and single crystals obtained from CH(2)Cl(2) solutions have been characterized crystallographically. The molecular structures feature a quasi-linear Mn(III)-Ni(II)-Ni(II)-Ni(II)-Mn(III) core with six-coordinate metal ions, where elongated axes of all the distorted octahedral coordination polyhedra are aligned parallel and are fixed with respect to each other by intramolecular hydrogen bonds. 1 and 2 exhibit quite strong ferromagnetic exchange interactions throughout (J(Mn-Ni) ≈ 40 K (1) or 42 K (2); J(Ni-Ni) ≈ 22 K (1) or 18 K (2)) that lead to an S(tot) = 7 ground state, and a sizable uniaxial magnetoanisotropy with D(mol) values -0.55 K (1) and -0.45 K (2). These values are directly derived also from frequency- and temperature-dependent high-field EPR spectra. Slow relaxation of the magnetization at low temperatures and single-molecule magnet (SMM) behavior are evident from frequency-dependent peaks in the out-of-phase ac susceptibilities and magnetization versus dc field measurements, with significant energy barriers to spin reversal U(eff) = 27 K (1) and 22 K (2). Pronounced quantum tunnelling steps are observed in the hysteresis loops of the temperature- and scan rate-dependent magnetization data, but with the first relaxation step shifted above (1) or below (2) the zero crossing of the magnetic field, despite the very similar molecular structures. The different behavior of 1 and 2 is interpreted in terms of antiferromagnetic (1) or ferromagnetic (2) intermolecular interactions, which are discussed in view of the subtle differences of intermolecular contacts within the crystal lattice.

  8. Optimizing Whole House Deep Energy Retrofit Packages: A Case Study of Existing Chicago-Area Homes

    Directory of Open Access Journals (Sweden)

    Honnie Aguilar Leinartas

    2015-05-01

    Full Text Available Improving the energy efficiency of the residential building stock plays a key role in mitigating global climate change. New guidelines are targeting widespread application of deep energy retrofits to existing homes that reduce their annual energy use by 50%, but questions remain as to how to identify and prioritize the most cost-effective retrofit measures. This work demonstrates the utility of whole building energy simulation and optimization software to construct a “tool-box” of prescriptive deep energy retrofits that can be applied to large portions of the existing housing stock. We consider 10 generally representative typology groups of existing single-family detached homes built prior to 1978 in the Chicago area for identifying cost-optimal deep energy retrofit packages. Simulations were conducted in BEopt and EnergyPlus operating on a cloud-computing platform to first identify cost-optimal enclosure retrofits and then identify cost-optimal upgrades to heating, ventilation, and air-conditioning (HVAC systems. Results reveal that prescriptive retrofit packages achieving at least 50% site energy savings can be defined for most homes through a combination of envelope retrofits, lighting upgrades, and upgrades to existing HVAC system efficiency or conversion to mini-split heat pumps. The average upfront cost of retrofits is estimated to be ~$14,400, resulting in average annual site energy savings of ~54% and an average simple payback period of ~25 years. Widespread application of these prescriptive retrofit packages across the existing Chicago-area residential building stock is predicted to reduce annual site energy use by 3.7 × 1016 J and yield approximately $280 million USD in annual energy savings.

    Family oriented innovative programs extend the reach of many traditional out-of-school venues to involve the entire family in learning in comfortable and fun environments. Research shows that parental involvement is key to increasing student achievement outcomes, and family-oriented programs have a direct impact on student performance. Because families have the greatest influence on children's attitudes towards education and career choices, we have developed a Family Science program that provides families a venue where they can explore the importance of science and technology in our daily lives by engaging in learning activities that change their perception and understanding of science. NASA Family Science Night strives to change the way that students and their families participate in science, within the program and beyond. After three years of pilot implementation and assessment, our evaluation data shows that Family Science Night participants have positive change in their attitudes and involvement in science.  Even after a single session, families are more likely to engage in external science-related activities and are increasingly excited about science in their everyday lives.  As we enter our dissemination phase, NASA Family Science Night will be compiling and releasing initial evaluation results, and providing facilitator training and online support resources. Support for NASA Family Science Nights is provided in part through NASA ROSES grant NNH06ZDA001N.

  11. Family unification in five and six dimensions

    International Nuclear Information System (INIS)

    Babu, K.S.; Barr, S.M.; Kyae, Bumseok

    2002-01-01

    In family unification models, all three families of quarks and leptons are grouped together into an irreducible representation of a simple gauge group, thus unifying the standard model gauge symmetries and a gauged family symmetry. Large orthogonal groups, and the exceptional groups E 7 and E 8 , have been much studied for family unification. The main theoretical difficulty of family unification is the existence of mirror families at the weak scale. It is shown here that family unification without mirror families can be realized in simple five-dimensional and six-dimensional orbifold models similar to those recently proposed for SU(5) and SO(10) grand unification. It is noted that a family unification group that survived to near the weak scale and whose coupling extrapolated to high scales unified with those of the standard model would be evidence, accessible in principle at low energy, of the existence of small (Planckian or GUT-scale) extra dimensions

  12. Tyrosine kinase inhibitors: Multi-targeted or single-targeted?

    Science.gov (United States)

    Broekman, Fleur; Giovannetti, Elisa; Peters, Godefridus J

    2011-02-10

    Since in most tumors multiple signaling pathways are involved, many of the inhibitors in clinical development are designed to affect a wide range of targeted kinases. The most important tyrosine kinase families in the development of tyrosine kinase inhibitors are the ABL, SCR, platelet derived growth factor, vascular endothelial growth factor receptor and epidermal growth factor receptor families. Both multi-kinase inhibitors and single-kinase inhibitors have advantages and disadvantages, which are related to potential resistance mechanisms, pharmacokinetics, selectivity and tumor environment. In different malignancies various tyrosine kinases are mutated or overexpressed and several resistance mechanisms exist. Pharmacokinetics is influenced by interindividual differences and differs for two single targeted inhibitors or between patients treated by the same tyrosine kinase inhibitor. Different tyrosine kinase inhibitors have various mechanisms to achieve selectivity, while differences in gene expression exist between tumor and stromal cells. Considering these aspects, one type of inhibitor can generally not be preferred above the other, but will depend on the specific genetic constitution of the patient and the tumor, allowing personalized therapy. The most effective way of cancer treatment by using tyrosine kinase inhibitors is to consider each patient/tumor individually and to determine the strategy that specifically targets the consequences of altered (epi)genetics of the tumor. This strategy might result in treatment by a single multi kinase inhibitor for one patient, but in treatment by a couple of single kinase inhibitors for other patients.

  15. Mandolin Family Instruments

    Science.gov (United States)

    Cohen, David J.; Rossing, Thomas D.

    The mandolin family of instruments consists of plucked chordophones, each having eight strings in four double courses. With the exception of the mandobass, the courses are tuned in intervals of fifths, as are the strings in violin family instruments. The soprano member of the family is the mandolin, tuned G3-D4-A4-E5. The alto member of the family is the mandola, tuned C3-G3-D4-A4. The mandola is usually referred to simply as the mandola in the USA, but is called the tenor mandola in Europe. The tenor member of the family is the octave mandolin, tuned G2-D3-A3-E4. It is referred to as the octave mandolin in the USA, and as the octave mandola in Europe. The baritone member of the family is the mandocello, or mandoloncello, tuned C2-G2-D3-A3. A variant of the mandocello not common in the USA is the five-course liuto moderno, or simply liuto, designed for solo repertoire. Its courses are tuned C2-G2-D3-A3-E4. A mandobass was also made by more than one manufacturer during the early twentieth century, though none are manufactured today. They were fretted instruments with single string courses tuned E1-A1-D2-G2. There are currently a few luthiers making piccolo mandolins, tuned C4-G4-D5-A5.

  17. Changing families, changing workplaces.

    Science.gov (United States)

    Bianchi, Suzanne M

    2011-01-01

    American families and workplaces have both changed dramatically over the past half-century. Paid work by women has increased sharply, as has family instability. Education-related inequality in work hours and income has grown. These changes, says Suzanne Bianchi, pose differing work-life issues for parents at different points along the income distribution. Between 1975 and 2009, the labor force rate of mothers with children under age eighteen increased from 47.4 percent to 71.6 percent. Mothers today also return to work much sooner after the birth of a child than did mothers half a century ago. High divorce rates and a sharp rise in the share of births to unmarried mothers mean that more children are being raised by a single parent, usually their mother. Workplaces too have changed, observes Bianchi. Today's employees increasingly work nonstandard hours. The well-being of highly skilled workers and less-skilled workers has been diverging. For the former, work hours may be long, but income has soared. For lower-skill workers, the lack of "good jobs" disconnects fathers from family obligations. Men who cannot find work or have low earnings potential are much less likely to marry. For low-income women, many of whom are single parents, the work-family dilemma is how to care adequately for children and work enough hours to support them financially. Jobs for working-class and lower middle-class workers are relatively stable, except in economic downturns, but pay is low, and both parents must work full time to make ends meet. Family income is too high to qualify for government subsidized child care, but too low to afford high-quality care in the private market. These families struggle to have a reasonable family life and provide for their family's economic well-being. Bianchi concludes that the "work and family" problem has no one solution because it is not one problem. Some workers need more work and more money. Some need to take time off around the birth of a child

    Full Text Available Abstract Background Large genomes contain families of highly similar genes that cannot be individually identified by microarray probes. This limitation is due to thermodynamic restrictions and cannot be resolved by any computational method. Since gene annotations are updated more frequently than microarrays, another common issue facing microarray users is that existing microarrays must be routinely reanalyzed to determine probes that are still useful with respect to the updated annotations. Results PICKY 2.0 can design shared probes for sets of genes that cannot be individually identified using unique probes. PICKY 2.0 uses novel algorithms to track sharable regions among genes and to strictly distinguish them from other highly similar but nontarget regions during thermodynamic comparisons. Therefore, PICKY does not sacrifice the quality of shared probes when choosing them. The latest PICKY 2.1 includes the new capability to reanalyze existing microarray probes against updated gene sets to determine probes that are still valid to use. In addition, more precise nonlinear salt effect estimates and other improvements are added, making PICKY 2.1 more versatile to microarray users. Conclusions Shared probes allow expressed gene family members to be detected; this capability is generally more desirable than not knowing anything about these genes. Shared probes also enable the design of cross-genome microarrays, which facilitate multiple species identification in environmental samples. The new nonlinear salt effect calculation significantly increases the precision of probes at a lower buffer salt concentration, and the probe reanalysis function improves existing microarray result interpretations.

    Between 1901-1921, India gained 12.9 million people because mortality remained high. The death rate fell between 1921-1951, but birth rates remained the same. Therefore 110 million people were added--2 times the population increase between 1891-1921. Between 1951-1981, the population increased to 324 million. Socioeconomic development was responsible for most of the downward trend in the birth rate during the 20th century. Even though large families were the norm in early India, religious leaders encouraged small family size. The 1st government family planning clinics in the world opened in Mysore and Bangalore in 1930. Right before Independence, the Bhore Committee made recommendations to reduce population growth such as increasing the age of marriage for girls. Since 1951 there has been a change in measures and policies geared towards population growth with each of the 7 5-Year Plans because policy makers applied what they learned from each previous plan. The 1st 5-Year Plan emphasized the need to understand what factors contribute to population growth. It also integrated family planning services into health services of hospitals and health centers. The government was over zealous in its implementation of the sterilization program (2nd 5-Year Plan, 1956-1961), however, which hurt family planning programs for many years. As of early 1992, sterilization, especially tubectomy, remained the most popular family planning method, however. The 7th 5-Year Plan changed its target of reaching a Net Reproductive Rate of 1 by 2001 to 2006-2011. It set a goal of 100% immunization coverage by 1990 but it did not occur. In 1986, the Ministry of Health and Family Welfare planned to make free contraceptives available in urban and rural areas and to involve voluntary organizations. The government needs to instill measures to increase women's status, women's literacy, and age of marriage as well as to eliminate poverty, ensure old age security, and ensure child survival and

    Available data on the impact of certain types of families is lacking, and the results are often misleading with respect to maladjustment. Following a description of variations in delinquent activity and behaviour problems according to family type, the authors analyse the difficulties in the operation of family systems. Comparisons of six family types apply to data from 763 boys aged 10, 319 female and 426 male adolescents, aged 14 and 15: intact families, father-based and mother-based single-parent families, father-based and mother-based reconstituted families and substitute families. The article's data show that in the late eighties, nearly 40 per cent of children and adolescents living in low-income districts in Montreal belonged to disunited families. In addition, the data confirm a classic observation: in comparison with intact families, disunited families are underprivileged in relation to living conditions, deficient in relation to psychosocial functioning, and propitious to behaviour problems and delinquent activity. In addition, it has been established that certain disunited family types represent a considerable risk factor. The damaging effect of family structure increases in the following order: intact families, mother-based single-parent families, mother-based reconstituted families, substitute families, father-based reconstituted families and father-based single-parent families. Finally, certain intervention methods are suggested to help prevent behaviour and family problems.

    The existence of equilibrium solutions for a lubricated system consisting of an articulated body sliding over a flat plate is considered. Though this configuration is very common (it corresponds to the popular tilting-pad thrust bearings), the existence problem has only been addressed in extremely simplified cases, such as planar sliders of infinite width. Our results show the existence of at least one equilibrium for a quite general class of (nonplanar) slider shapes. We also extend previous results concerning planar sliders.

  16. Does GaH5 exist?

    The existence or nonexistence of GaH5 has been widely discussed [N. M. Mitzel, Angew. Chem. Int. Ed. 42, 3856 (2003)]. Seven possible structures for gallium pentahydride have been systematically investigated using ab initio electronic structure theory. Structures and vibrational frequencies have been determined employing self-consistent field, coupled cluster including all single and double excitations (CCSD), and CCSD with perturbative triples levels of theory, with at least three correlation-consistent polarized-valence-(cc-pVXZ and aug-cc-pVXZ) type basis sets. The X˜A'1 state for GaH5 is predicted to be weakly bound complex 1 between gallane and molecular hydrogen, with Cs symmetry. The dissociation energy corresponding to GaH5→GaH3+H2 is predicted to be De=2.05kcalmol-1. The H-H stretching fundamental is predicted to be v =4060cm-1, compared to the tentatively assigned experimental feature of Wang and Andrews [J. Phys. Chem. A 107, 11371 (2003)] at 4087cm-1. A second Cs structure 2 with nearly equal energy is predicted to be a transition state, corresponding to a 90° rotation of the H2 bond. Thus the rotation of the hydrogen molecule is essentially free. However, hydrogen scrambling through the C2v structure 3 seems unlikely, as the activation barrier for scrambling is at least 30kcalmol-1 higher in energy than that for the dissociation of GaH5 to GaH3 and H2. Two additional structures consisting of GaH3 with a dihydrogen bond perpendicular to gallane (C3v structure 4) and an in-plane dihydrogen bond [Cs(III) structure 5] were also examined. A C3v symmetry second-order saddle point has nearly the same energy as the GaH3+H2 dissociation limit, while the Cs(III) structure 5 is a transition structure to the C3v structure. The C4v structure 6 and the D3h structure 7 are much higher in energy than GaH3+H2 by 88 and 103kcalmol-1, respectively.

  17. Familial macrocephaly

    We reported 63 macrocephalic children with special emphasis on 16 cases with familial macrocephaly. Of the 16 children with familial macrocephaly, 13 were boys. Foureen parents (13 fathers and 1 mother) had head sizes above 98th percentile. Three of 5 brothers and 5 of 8 sisters also had large heads. The head circumference at birth was known for 14 of the children and it was above the 98th percentile in 7 patients. Subsequent evaluations have shown the head size of these children to be following a normal growth curve. Some of the children were hypotonic as infants, but their development was generally normal. CT scans usually clearly distinguished these children from those with hydorocephalus. The familial macrocephalic children had ventricular measurements which were within the normal range, but absolute measurements of the ventricular size may be misleading, because the CT appearance was of mildly dilated ventricles in half of them.

    The study on phenomena in the super high energy region, Σ E j > 1000 TeV revealed events that present a big dark spot in central region with high concentration of energy and particles, called halo. Six super families with halo were analysed by Brazil-Japan Cooperation of Cosmic Rays. For each family the lateral distribution of energy density was constructed and R c Σ E (R c ) was estimated. For studying primary composition, the energy correlation with particles released separately in hadrons and gamma rays was analysed. (M.C.K.)

  4. Recent disruption of an asteroid from the Eos family

    A key difficulty with searching for partially differentiated asteroids arises from the fact that a crust covers the exterior of the body, and, consequently, should hide the melted interior. This motivates an alternative approach of examining members of asteroid families, i.e., fragments of single large bodies, many of which were in the size regime capable of igneous differentiation, that have been disrupted by catastrophic collisions. Such families could provide a stratigraphic cross section across the interior of the parent asteroid [1]. With more than 10,000 known members, the Eos dynamical family is one of the most numerous and earliest recognized asteroid families [2]. Interestingly, the estimated ˜220-km-diameter parent body [3] is well within the size range capable of differentiation. Thus, existing family members should contain fragments of the deep interior. The Eos family has the highest diversity of taxonomic classes than any other known family [4]. Many members are of K spectral type, which is uncommon outside the family, and is similar to the spectra of CV, CK, CO, and CR carbonaceous chondrites [5]. This diversity leads to the suggestion that the Eos parent body was partially differentiated [4,6]. Thus, the Eos family may not only be a remnant of a partially differentiated parent body, but it could be the source of the CV-CK meteorite group. Here we report the discovery of a young subfamily of the Eos asteroid family. It may help understanding the mineralogical nature of the Eos asteroid family and of its parent body. By applying the hierarchical clustering method [7], we find an extremely compact 16-body cluster within the borders of the Eos family. We name the cluster (6733) 1992 EF, after its largest member. The statistical significance of this new cluster is estimated to be above 99%, indicating that its members share a common origin. All members of the cluster are found to be dynamically stable over long timescales. Backward numerical orbital

    1981-01-01

    We present a model for the unification of fermion families based on the gauge symmetry SO(15). It is a minimal SO(n) model which can accommodate the known fermions within a single irreducible representation. The model predicts four ordinary fermion families and four families of mirror fermions. The latter have V + A weak interactions, and their mass scale is predicted to be 10 2 GeV/c 2 . We argue that radiative corrections to the fermion masses can cause non-negligible mixing between ordinary and mirror fermions. The implications of these mixings for the weak interaction phenomenology and solar neutrinos are discussed. (orig.)

    We survey some known facts and open questions concerning the global properties of 3+1 dimensional space--times containing a compact Cauchy surface. We consider space--times with an $\\ell$--dimensional Lie algebra of space--like Killing fields. For each $\\ell \\leq 3$, we give some basic results and conjectures on global existence and cosmic censorship. For the case of the 3+1 dimensional Einstein equations without symmetries, a new small data global existence result is announced.
