    It has been claimed that there are universal goals of child-rearing, such as survival of the child or the promotion of their capacity to contribute to economic and social reproduction. Yet in certain circumstances parents appear to pursue child-rearing practices that actively harm children, threaten their survival and inhibit their ability to grow…

  6. Funding child rearing: child allowance and parental leave.

    Science.gov (United States)

    Walker, J R

    1996-01-01

    This article proposes two financing plans to address what the author identifies as the two primary concerns in the child care field: (1) a child allowance for poor and near-poor households to address the child care problems of low-income families, and (2) a program of voluntary parental leave, available to all parents at child birth or adoption, to ensure the adequacy of infant care. The child allowance plan would cover the first three children in families up to 175% of the poverty level (more than 22 million children) at an annual cost of $45 billion. The author suggests that the allowance could be financed by redirecting funds from existing income support (for example, Aid to Families with Dependent Children), tax credit, and tax deduction programs. Financing the parental leave program would require new revenues, generated by an employee-paid increase in payroll tax totaling 3.5%. Each employee's contributions would create a parental leave account (PLA). Families could use the funds in these accounts to cover the cost of a one-year leave from work after the birth or adoption of a child. If families did not have enough dollars in their accounts to cover the cost of the leave, the federal government would extend a low-interest loan to them, which they would have to pay back. The amount individuals receive through Social Security would be adjusted upward or downward according to the balances in their parental leave accounts at retirement. The author suggests that both proposals would help parents balance work and family obligations and protect parental freedom of choice over the care and upbringing of their children.

    Full Text Available BACKGROUND: The experiences of the commercial sex workers as they fulfill the role of being a parent, have rarely been reported. Considering their socioeconomic background, profession and work pattern, the women are bound to face major challenges. AIMS: To describe child bearing, family support, dietary practices and various placement options for raising children. STUDY DESIGN : A cross-sectional descriptive study of brothel- based commercial sex workers. STATISTICAL ANALYSIS : X2 test, Fisher′s Exact test RESULTS: Some commercial sex workers continued pregnancy with the hope of security and support, while others were compelled to do so, as they report late for medical termination of pregnancy. A group of sex workers (Devdasis received support during pregnancy, delivery, puerperium and child-rearing. The role and responsibilities of raising the child, depended upon the kind of family support available to the mothers. Being a single parent, stigma of the profession, odd working hours and variable family support were major challenges, while the fact that the women were earning, availability of rehabilitation centers, the homogeneous groups within the brothels, supportive peers and local non governmental organizations were factors which helped them in the process of raising their children. CONCLUSIONS : Day care centers and night shelters should be opened up in the red light area where the children can be looked after, during the working hours. The sex workers should be educated about weaning and nutrition. The role of peer workers and NGOs was very important in helping the women raise their children.

  13. [Recalled parental rearing and the wish to have a child - are there associations?].

    2002-07-01

    The present study concerns the impact of recalled parental rearing behaviour on both the intensity of the wish to have a child and on different motives to have a child. Until now there are no empirical studies as to this objective. Our study is based on a representative sample of 1509 persons aged 18 to 50 years. The statistical analyses were restricted to those subjects who lived in partnership and reported an actual wish to have a child (n = 331). The data were assessed by self-reporting scales: The Questionnaire of Recalled Parental Rearing Behaviour "Fragebogen zum erinnerten elterlichen Erziehungsverhalten, FEE", the Partnership Questionnaire "Partnerschaftsfragebogen, PFB", and the Leipzig Questionnaire of Motives to Have a Child "Leipziger Fragebogen zu Kinderwunschmotiven, LKM". A recalled parental rearing behaviour, which was characterized as having been rejective, overprotective and less emotionally warm was associated with such motives which do not promote the wish to have own children (fear of personal restrictions and a low degree of social support). Simultaneously, a negative parental rearing behaviour was correlated with a stronger desire for social recognition by an own child. The recalled maternal rearing behaviour was altogether stronger associated with motives to have a child than the paternal. On the other hand, no relevant associations could be found between the recalled parental rearing behaviour and the intensity of the wish to have a child. PMID:12181772

    2000-09-01

    This study was an exploratory examination of the influence of mothers' teaching behaviors, strategies, and child-rearing attitudes on their children's ability to delay gratification. In an externally imposed delay of gratification situation, 30 mothers from a rural university community taught their children strategies that could help them refrain from touching a brightly wrapped present when the mothers left the room. Results showed that mothers of children who did not delay gratification exhibited teaching behaviors and child-rearing attitudes consistent with a permissive parenting style, whereas mothers of children who did delay gratification exhibited teaching behaviors and child-rearing attitudes consistent with an authoritative parenting style. The results of this study are discussed with respect to the development of children's self-control and self-regulatory abilities. PMID:10971908

  19. The relationships of child and parent factors with children's anxiety symptoms: parental anxious rearing as a mediator.

    2012-10-01

    A considerable body of research has identified various child and parent factors that contribute to and maintain anxiety symptoms in children. Yet relatively few studies have examined child factors (including threat-based cognitive bias, neuroticism, gender, puberty and age) as well as parent factors (including maternal anxiety and child-rearing style) in association with child anxiety symptoms, and the extent to which these factors serve as unique predictors of child anxiety. Moreover, research is lacking on whether parent factors such as child-rearing style, which is often targeted in early intervention and treatment programs, might mediate the association between child factors such as neuroticism, and child anxiety symptoms. In a sample of 85 children between 7 and 12 years of age with varying levels of anxiety, including those with diagnosed anxiety disorders, results showed that children were more anxious when they were reported to be more advanced in pubertal status by their parents, when they had a tendency to interpret more threat in ambiguous situations, and when they self-reported more neuroticism. Regarding parent factors, maternal self-reported trait anxiety and children's perceptions of their mother as having an anxious child-rearing style were associated with higher levels of child anxiety. Moreover, when these correlates of child anxiety were examined in a multivariate model to identify those that had direct as well as indirect associations via maternal anxious child-rearing style, child neuroticism remained as a significant and unique predictor of child anxiety that was also mediated by maternal anxious-rearing. Child neuroticism also mediated the relationship between child pubertal stage and anxiety symptoms. Results are discussed in terms of relevant theory and empirical evidence regarding the roles of both child and parent factors in the development of child anxiety.

  20. [Supporting the Love, Marriage, and Child-Rearing of Persons with Schizophrenia].

    Persons with schizophrenia and their families have strong interests and hopes for love, marriage, pregnancy, and child-rearing. These experiences often lead to recovery from schizophrenia. There are many partners with schizophrenia who enjoy fruitful lives even with their disability. However, only some persons can enter into such lives in the real world in Japan and other countries. This leads persons with schizophrenia to develop a discouraged and disappointed attitude, and also causes professionals of mental health to develop indifference or pessimism about these issues. Schizophrenics are thought to have interests in love and sexual behavior just as strong as the general population. I discuss with my patients about these issues and working life early in the course of treatment. Because they lose their chance to learn adult behavior in social lives with peers due to the beginning of schizophrenia, they need an opportunity to participate in a social situation to learn knowledge and skills of dating and related behaviors, and systematic education such as psycho-education and social skills training should be provided. Continuing married life and child-rearing require more support from experts with rich experience and knowledge. Psychiatrists are required to participate in shared decision-making about medication during pregnancy and breast-feeding, as well as provide knowledge on the benefits and risks of antipsychotics. Net-working with the family, professionals of child welfare, and the community is necessary to support child-rearing. Urakawa Bethel's House was introduced as a pioneering concept to support love, marriage, and child-rearing. Finally, professionals' negative or indifferent attitudes toward these issues are discussed in the setting of treatment. I hope that professionals of mental health will think about these issues from the standpoints of persons with schizophrenia and their families.

    The effects of maternal child-rearing attitudes, as measured by the Child Rearing Practices Report, on 5-yr.-old children's Verbal IQ and Performance IQ were investigated in a Scandinavian sample of 108 boys and 126 girls. The maternal child-rearing attitude of Restrictiveness, as defined by scores on the Report, showed negative relations to the cognitive measures. However, the significant negative relation between Restrictiveness and Verbal IQ, obtained for both sexes, disappeared when the effects of maternal IQ and socioeconomic status were controlled. The maternal child-rearing attitude of Nurturance, as defined by scores on the Report, was significantly related to Verbal IQ and Performance IQ for boys only. Significant relationships between scores on Nurturance and cognitive abilities of boys remained when the effects of maternal IQ and socioeconomic status were controlled. PMID:8873781

    1987-04-01

    Longitudinal data involving 106 children and their parents were used to test preschool child-rearing implications of Carl Rogers's theory of creativity-fostering environments (Rogers, 1954). Indices were developed for each parent and for each mother-father combination that reflected the degree to which the parents' child-rearing practices and interactions with their preschool children matched the recommendations implicit in Rogers's description of a creativity-fostering environment. The three indices of Rogers-prescribed child-rearing practices each correlated positively (rs = .38 to .46) and significantly (all ps less than .001) with a composite index of creative potential in early adolescence, 7 to 11 years later. Rogers-prescribed preschool child-rearing practices also emerged as significant antecedents of adolescent creative potential in regression/path analyses that held constant the influence of sex, preschool intelligence, and preschool creative potential. Theoretical and methodological aspects of the study are discussed.

    This study elucidated the skills of mothers who used to build positive interpersonal relationships with people they met through child-rearing. The research method was qualitative descriptive study. The participants were 24 mothers who had children between ages of one and four years. These participants were recruited at child-rearing salons and childcare centers located in various municipalities in Japan. The survey period was from September 2013 to July 2014. The mothers' interpersonal relationship-building skills were described by six categories: “ability to strive for new encounters,” “ability to try to interact socially with others,” “ability to choose compatible people,” “ability to continuously maintain good relationships,” “ability to take action suitable to a situation,” and “ability to build positive relationships with parents-in-law.” Cognitive aspects of assessing and understanding the interactions that occur during exchanges and behavioral aspects guided by these cognitions were identified within these skills. This study contributed to providing a framework to understand mothers' interpersonal relationship-building skills for public health nurses involved in child-rearing support.

    Bögels, Susan M; Brechman-Toussaint, Margaret L

    2006-11-01

    Family studies have found a large overlap between anxiety disorders in family members. In addition to genetic heritability, a range of family factors may also be involved in the intergenerational transmission of anxiety. Evidence for a relationship between family factors and childhood as well as parental anxiety is reviewed. Four groups of family variables are considered: (I) attachment; (II), aspects of family functioning, such as marital conflict, co-parenting, functioning of the family as a whole, and sibling relationships; (III) parental rearing strategies; and (IV) beliefs that parents hold about their child. The reviewed literature provides evidence for an association between each of these family factors and child anxiety. However, there is little evidence as yet that identified family factors are specific to child anxiety, rather than to child psychopathology in general. Moreover, evidence for a relationship between child anxiety and family factors is predominantly cross-sectional. Therefore, whether the identified family factors cause childhood anxiety still needs to be investigated. Further research that investigates mechanisms mediating the relationship between family factors and child anxiety is also called for. Finally, parental beliefs are identified as important predictors of parental behaviour that have largely not been investigated in relation to child anxiety disorders. PMID:16473441

    Full Text Available Introduction Domestic violence against children is a global issue which devastates family bonds and threatens individuals' health in mental, physical as well as sexual aspects (Sajadifar 2002:11. There are a lot of factors involving in domestic violence against children. It seems that the parents' child-rearing style is an important factor that plays a pivotal role in decrease or increase of violence against children. Child-rearing style can act as a predicator of social and mental development, academic performance, welfare and even the potentiality of children's problematic behaviors in the future. Child-rearing style can be both the facilitator and inhibitor of antisocial behavior, like domestic violence against adolescent and children. Those studies that talk about antisocial behavior as a result of offensive child-rearing styles have mainly emphasized autocratic parents (Adams, Mount & Mayer 1998. Many studies have indicated that unstable and unorganized child-rearing style is more likely to increase in domestic violence against children. On the other hand, other studies talk about those child-rearing styles which reduce violence against children, emphasizing stable and controlled punishments, in proportion to improper behavior committed by children, which may decrease violence against them (Denton & Kaspf 1994, Krunkuych & Gyrdan 1987. Therefore, with regard to this issue and the importance of the role that parenting styles play in child-rearing, the aim of this study is to examine the relationship between parents' child-rearing styles and domestic violence against children in Ahvaz city.

    2014-10-01

    Full Text Available Background: Child-rearing remains a concern within our communities, especially because families of today lack primary parents due to multifaceted challenges such as working mothers, diseases and violence. Health-promoting school initiatives are necessary because they allow a multifaceted approach to child-rearing. They further provide a conducive environment for continued schoolchild-rearing moving from home to school. Objectives: This study promotes an integrated approach to school care using the African concept of Ubuntu – solidarity and sense of community – as a point of departure. The socio-ecological model was used, which includes the work of the school healthcare nurse in contributing to holistic health services. Method: An integrative review was conducted in January 2013, which included methodology studies, a theory review and a variety of studies related to school health. The studies were categorised according to school health, Ubuntu and the socio-ecological model. Findings: The role of school healthcare nurses entails acting as a liaison officer between a variety of stakeholders who work together to shape the future of children. Conclusion: Ubuntu, together with the socio-ecological model, can assist us to involve an entire community to raise children. This knowledge serves as a background to the planning of a school health programme. The role of the nurse in school health can also assist in collaborative efforts to formulate the programme and develop the competencies that will inform school health nurse training curricula.

    Fertility declines across Europe and the Anglo-world have been explained as the result of reversals of intergenerational flows of wealth. According to this theory, the child was transformed from an economically-useful household asset to an emotionally-valued parental burden. This article is based on a comparative study of changing understandings of parenthood in three provincial English localities between 1850 and 1914. It works from the premise that in order to make sense of reproductive behaviour, it is essential to examine the meanings that men and women attached to childlessness, child-rearing and parenthood. It is argued that there was not a universal shift that made children into burdens. New understandings of the duties of parenthood did develop, but these were founded on class-, gender- and place-specific interpretations. These encouraged a minority of fathers and mothers to believe that together they had the capacity to improve the lives of their sons and daughters in pioneering ways. Given that husbands and wives had distinct motives for avoiding rearing many children and that the discussion of reproduction was shrouded in silence, the dissemination and use of new ideals of family was crucial in enabling birth control to be thought about respectably within marriage.

    The correspondence between self-reported child-rearing attitudes and practices and actual child management was examined among 68 mothers of young children. Data on mothers' verbal and physical control techniques along with children's responses (cooperation vs. resistance) were obtained during 90 min of spontaneous interaction in a naturalistic setting. Self-report data (the Block Q-Sort) were obtained 1-2 weeks later. The Block Q-Sort factors were combined to represent authoritarian and authoritative patterns of attitudes. The authoritarian pattern was positively associated with the use of direct commands, physical enforcements, reprimands, and prohibitive interventions, and negatively associated with the use of suggestions. The authoritative pattern was positively related to the use of suggestions and positive incentives, and negatively related to the use of physical enforcements, prohibitive interventions, and direct commands. Mothers' enjoyment of the parental role and their negative affect toward the child, as expressed in the Block Q-Sort, were more a result of the child's cooperation/resistance during the interaction than predictors of maternal control strategies.

    1995-01-01

    Abstract A Questionnaire for the Parent-Child Interaction (VOKI) has been developed by adapting Krohne's German ESI for the Flemish high school population. The psychometric characteristics of the adaptation are satisfying. The ESI factor structure has been replicated and the VOKI scales are perfectly comparable to the original German scales. Further research on the VOKI and two questionnaires assessing achievement related concepts such as test anxiety, procrastination and achievement motivation yielded correlational patterns partly predicted from Krohne's Two-Process Model. The relations between parental child-rearing styles and competence and consequence expectancies are in line with this model, whereas test anxiety and procrastination seem more complexly determined.

    Full Text Available Background: India contributes a large proportion to global under-five child mortality. One of the determinants of child morbidity and mortality is the "child rearing practices." Socio-economic environment, child rearing practices and nutritional status play a synergistic role. Materials and Methods: Information was collected by exit interviews from married women attending out-patient departments of three primary health centers. Data was collected during December, 2009 using pretested questionnaire Married women in reproductive age group with youngest child in the age group of 1-5 years were eligible for inclusion. To assess the child rearing knowledge and practices (CRKP, a composite score was calculated based on 10 variables and categorized into satisfactory and unsatisfactory. Results: A total of 100 eligible married women were included in the study. About half of the women were in the age group of 25-35 years, 80% belonged to social class V and VI majority (63% were literate and 70% had ≥2 children. With the increase in literacy status, there was the increase in proportion of women who had satisfactory CRKP and decrease in proportion of women who had given pre-lacteal feed. Among women who had three children, 15 out of 39 (38% had fully immunized their first child as compared with 25 out of 39 (64% for the second child and 38 out of 39 (97% for the third child. Immunization coverage increased as the birth order increased.

    This study examined the association between recollected parental child-rearing strategies and individual differences in self-regulation, socio-emotional adjustment, and psychopathology in early adulthood. Undergraduate participants (N = 286) completed the EMBU - a measure of retrospective accounts of their parents' child-rearing behaviors - as well as self-report measures of self-regulation and socio-emotional adjustment across the domains of eating disorder symptoms, physically risky behavior, interpersonal problems, personal financial problems, and academic maladjustment. A subset of participants also completed the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF). Parental warmth was found to be related to overall better self-regulation and improved interpersonal and academic adjustment. In contrast, both parental rejection and overcontrol were found to be related to general deficits in self-regulation as well as adjustment difficulties and psychopathology. Parental rejection was most closely related to internalizing clinical presentations like anxiety, depression, and somatization, whereas overcontrol was most aligned with increased hypomanic activation and psychoticism. Mediation analyses demonstrated that the relationships between parental child-rearing strategies and socio-emotional adjustment and psychopathology were partially mediated by self-regulation. Future directions are suggested, including basic and translational research related to better understanding the roles of parental child-rearing and self-regulation in the development of internalizing symptoms, activation, and psychotic symptoms.

Mothers from index families, in contrast to control mothers, were less attentive to their children's health needs, emphasized performance in some achievement-related areas, were more overprotective, and reported more negative affect toward the child. They also were more disorganized, less active with their children, and more unhappy, tense, and ineffective. Index parents secured lower scores in the areas of family interaction and social adjustment, and they experienced situational problems of considerable severity, including clinical depression in the well parent.

    Full Text Available Abstract Background Parenting programmes are effective in enhancing parenting practices and child development. This study evaluated the effects of a intervention with psychosocial stimulation (PS on the quality of the home environment and mothers’ child-rearing practices in a community-based trial with severely malnourished Bangladeshi children. Method Severely underweight children (n = 507, 6–24 months of age, were randomly assigned to five groups: PS; food supplementation (FS; PS + FS; clinic-control (CC; and, hospital-control (CH. PS included fortnightly follow-up visits for six months at community clinics where a play leader demonstrated play activities and gave education on child development and child rearing practices. FS comprised cereal-based supplements (150–300 kcal/day for three months. All groups received medical care, micronutrient supplements and growth monitoring. Mothers were given the Home Observation for Measurement of the Environment (HOME inventory and a questionnaire on parenting at baseline and after six months to assess the outcome. Results 322 children completed the study. After six months of intervention the PS + FS and PS groups benefitted in the total HOME score (depending on the comparison group, effect sizes varied from 0.66 to 0.33 SD The PS + FS and PS groups also benefitted in two HOME subscales: maternal involvement (effect sizes: 0.8 to 0.55 SD and play materials, (effect sizes: 0.46 to 0.6 SD, and child-rearing practices scores (effect size: 1.5 to 1.1 SD. The PS + FS group benefitted 4.0 points in total HOME score compared with CH, 4.8 points compared with CC and 4.5 points compared with FS (p  Conclusions Child-rearing practices of mothers of severely malnourished children and the quality of their home environment can be improved through community-based psychosocial stimulation with or without food supplementation. This may be of importance to promote child development.

    2015-12-01

    Full Text Available Background: Experiencing abuse during childhood affects the psychological well-being of individuals throughout their lives and may even influence their offspring by enhancing the likelihood of an intergenerational transmission of violence. Understanding the effects of childhood maltreatment on child-rearing practices and intimate partner violence might be of particular importance to overcome the consequences of violent conflicts in African societies. Objective: Using Burundi as an example, we aimed to explore the associations between childhood maltreatment, intimate partner violence, perceived partner intimidation, gender and the probability of violently acting out against one's own children or romantic partner. Methods: Amongst a sample of 141 men and 141 women in the capital of Burundi, we identified those who had biological children and those who lived or had lived in relationships. Using culturally appropriate instruments, we enquired about their exposure to childhood maltreatment and partner violence as well as their inclinations to act out violently. Results: We found that childhood maltreatment and perceived partner intimidation were strong predictors for the perpetration of violence against children. Moreover, we found that women were more likely to use violence against children if they experienced partner violence and less likely to resort to violence if they felt intimidated. Men were more likely to perpetrate violence against their partner. Childhood maltreatment was again a strong predictor. The more women experienced partner violence, the more they fought back. Conclusions: Childhood maltreatment is a strong predictor for domestic violence and has to be addressed to interrupt the cycle of violence in post-conflict countries.

    The aim of the study is to investigate metaparenting (effortful, deliberate cognition about parenting) in parents of children at risk for ADHD including predictors, correlates, and intervention outcomes. Parents (n = 68) of children with significant ADHD symptoms (i.e., ≥ 6 inattentive or hyperactive/impulsive symptoms with impairment in ≥ 2 settings, mostly un-medicated) provided ratings of metaparenting, parenting stress and practices, and child ADHD symptoms before and after parent training. Parents were predominantly Caucasian, in their upper thirties, and most had schooling beyond high school. We investigated the relation between metaparenting and baseline predictors, and whether metaparenting predicted (1) parenting behaviors at baseline, (2) attrition, and (3) parenting stress and parent/child behaviors at outcome. More educated mothers, with fewer people living in the home, and higher levels of parenting stress, reported more metaparenting. Parents with lower problem-solving and assessing scores reported more inconsistent parenting, and those with lower problem-solving scores were more likely to drop out of parent training. Higher problem-solving and reflecting scores at baseline were associated with more parental stress. Higher reflecting at baseline predicted child hyperactivity/impulsivity at outcome. Our findings indicate metaparenting is associated with parenting behaviors and decisions to complete parent training. Furthermore, metaparenting appears to be a complex, finely nuanced construct with both positive and negative associations with reports of parenting practices and stress.

    2004-02-01

    Semi-structured interviews of 76 Sami mothers and 58 Sami fathers, and 86 Norwegian mothers and 58 Norwegian fathers of four-year olds, revealed consistent cross-cultural differences in parenting. ANCOVA results showed that parental permissiveness was higher in the Sami group. Moreover, the effect of ethnicity was different for boys and girls (mothers' reports). Co-sleeping and self-regulation of food and sleep were commonly practiced in the Sami, but not in the Norwegian families. Sami children were more socially independent than their Norwegian peers. Indirect or internal types of control were used more by Sami parents, and they were less tolerant of child aggression, in the form of temper tantrums and displays of jealousy. These patterns are similar to those found in other indigenous cultures in the circumpolar region. The results are discussed with reference to the Individualism-Collectivism dimension. The study challenges the Individualism-Collectivism construct for apparently confounding the individualism common in European liberalism with the individual autonomy commonly encountered among hunting-gathering peoples.

    -graders from public and private schools in Southeastern Brazil. Standardized instruments were administered to parents/caretakers by trained interviewers, including screening questionnaires for mental health problems among children and parents/caretakers; a questionnaire on beliefs and attitudes; and a questionnaire for socio-economic status. Chi-square tests and logistic regression models were used for statistical analysis. RESULTS: We found 35.2% prevalence of clinical/borderline cases among students. Parents/caretakers that believed in corporal punishment as a child-rearing method used physical aggression towards their children more frequently (64.8%. Logistic regression models showed that the act of hitting the child with a belt was associated to conduct problems and to overall mental health problems among schoolchildren in the presence of other risk factors: child gender (male, parents/caretakers with mental health problems, and adverse socioeconomic conditions. CONCLUSIONS: The high prevalence of mental health problems among schoolchildren and its association with child-rearing methods and mental health problems among parents/caretakers indicate the need for psycho-educational interventions aimed to reduce physical abuse and mental health problems in childhood.

    A large number of studies have proved that father's participation is important to the healthy growth of children. However, the relevant survey shows that the phenomenon of"father absence"is widespread in our country at present, which is not conducive to the development of young children, and will have a negative impact on the quality of human resources and national competitiveness as well. Based on the introduction of the current situation of father involvement in child rearing in China and the US, the comparison shows that the amount of time and participation patterns of Chinese fathers are obviously insufficient. And drawing lessons from the experience of the US, this study summs up that China should starts from the legislation, policy, educa⁃tion institutions, communities and families, etc., to promote fathers’participation in early childhood education.%大量研究证明,父亲参与对幼儿健康成长具有重要价值。然而,相关调查显示,目前我国“父亲缺失”的现象普遍存在。这既不利于幼儿发展,也将对我国未来人力资源质量和国家竞争力产生不利影响。比较分析中美父亲参与幼儿教养的现状发现,我国父亲在参与时间量和参与方式上都存在明显不足。美国经验启示我国应从立法、政策、教育机构、社区和家庭等方面入手,促进父亲参与幼儿教养。

    organizados en temas y categorías. ANÁLISIS DEL DISCURSO: Los resultados señalaron la restricción de los discursos de los entrevistados en función de sus condiciones de producción. Hubo diversidad de concepciones sobre educación y formas de educar, teniendo como puntos comunes el relato de la práctica de la punición física por todos los padres, inclusive entre aquellos que la condenan. Los discursos fueron marcados por la heterogeneidad y polifonía, sobresaliéndose el discurso de la tradición, el discurso religioso y el discurso científico popularizado. No fue observada expresión de concepto de interdicción legal de la práctica o de sus excesos por los participantes. CONCLUSIONES: La cultura de castigo físico se encuentra en transición, en que la tradición de permisividad se debilita y la interdicción se inicia lentamente. Refuerzo de acciones de represión legal a la práctica podría contribuir para acelerar el proceso de interdicción del castigo físico.OBJECTIVE: To describe parents' current perception of corporal punishment associated to child rearing and its practices.

    Full Text Available The study examined associations between parents' childrearing practices, behavior problems and pre-school children's social competence. A total of 48 mothers and 33 fathers, when their firstborn children were aged six, completed an interview about child-rearing practices and the Social Skills Rating System that also assesses behavior problems. Spearman correlations indicated positive associations between maternal coercive practices and children's behavior problems, especially those related to externalizing. Positive correlations were also found between fathers' coercive practices and internalizing problems, as well as among fathers' inductive and non-interference practices with children's cooperation and assertiveness, respectively. Girls' mothers reported higher levels of self-control and social competence than did boys' mothers. Moreover, lower SES mothers referred more coercive practices while higher SES mothers reported more inductive practices. Findings underscore the relationship between fathers' inductive practices and children's social competence. In addition, results suggested associations among both mothers' and fathers' coercive practices and children's behavior problems.O estudo investigou a relação das práticas educativas parentais, problemas de comportamento e a competência social de crianças pré-escolares.

  1. Familism, machismo and child rearing practices among Mexican Americans.

    Science.gov (United States)

    Tamez, E G

    1981-09-01

    Mexican Americans form the 2nd largest minority group in the US. Fertility is 50% higher than in any other ethnic group. Income levels are inordinately low. In 1970, 42% of Mexican Americans were indigent, making approxiamtely 4200 annually. The Mexican American poor can be categorized into newly arrived aliens or 2nd or 3rd generation American citizens. In the 1st instance, the couple is young and English is not spoken. 2nd or 3rd generation Mexican Americans speak English. The persistent socioeconomic status of the Mexican American relates directly to the level of education. 52% of all Mexican Americans do not finish high school. Paz and Remos described the Mexican in terms of Adler's inferiority model. Murillo stated that to an individual, the family--whether nuclear or extended--is the center of life. The inherent responsibility is that the individual behave properly lest the family be disgraced. The family provides emotional and material security. Familism was seen as a deterrant to utilization of health care services, although some studies claim opposing views. Familism and occupational stability related positively to seeking medical care when ill. Hayden believed that supreme male dominance, individualism, pride, wife beating, aversion to contraceptives, and other characteristics were attributable to machismo. A predominant pattern in Mexican American culture is that of elders' ordering young men and women to establish obedience and male dominance. The husband represents authority and the wife-mother maintains a role of complete devotion to her husband and children. Role differentiation is taught implicitly and explicitly from infancy. Studies on the psychological differences between the sexes indicated that females were oppressed and had lower self esteem than males. 18-24 year old Mexican Americans are becoming less insistent upon strict separation of sex roles and are beginning to reject the traditional Mexican notion of masculine superiority. The word machismo is derived from macho, which means male. The real macho possesses many traits of honor, dignity, and courage. he exemplifies masculine aggressiveness and sexual virility. The negative extremes of machismo center on absolute power in the form of violence and exploitation. Machismo is the underlying cause of family conflicts.

  10. [Child raising without violence--a right for every child].

    Science.gov (United States)

    Köhler, Marie; Lucas, Steven

    The view of children and child rearing has undergone a marked change in our country over the past 50 years. As the first country in the world, Sweden passed legislation 1979 on the prohibition of corporal punishment in the home. Many countries have followed suit, but at present, only 5,4% of the world's children have legal protection against violence and abuse. Children's rights are on the agenda, including work towards implementing the Convention on the Rights of the Child. Child abuse is nevertheless a major public health problem with serious implications in both childhood and adulthood, and is tied into both economic and social disadvantage. The childhood adversity we see is only the tip of the iceberg and continued efforts are necessary to identify and reduce the vulnerability of children and protect children's rights. Health care professionals have an important role to play. PMID:25405625

    1990-05-01

    To replicate and explore the associations of drawing genitalia on a human figure, child-rearing practices, and a history of alleged sexual abuse, we designed a cross-sectional study of 109 alleged child sexual abuse victims, ages 3 through 8 years, and a group of 109 comparison children matched for age, sex, race, and socioeconomic status but with no history of abuse. A standardized format was used to collect drawings, administer the Peabody Picture Vocabulary Test, and gather background data on medical, developmental, and child-rearing issues. Seven alleged sexual abuse victims and one comparison child spontaneously drew genitalia (p = 0.02, one-tailed Fisher Exact Test, estimated relative risk 7.96). No differences in drawing maturity (Draw-A-Man score) were identified, although Peabody Picture Vocabulary Test scores were higher in comparison children (82.1 vs. 91.0, p less than 0.01). Neither drawing genitalia nor history of alleged sexual abuse were significantly associated with histories of medical problems, enuresis, encopresis, urinary tract infection, or child-rearing practices related to sleeping, nudity, bathing, sexual abuse education, or exposure to sexually explicit materials. The similar patterns of child-rearing practices in both samples should make professionals cautious in attributing allegations of abuse to specific child-rearing practices. This study confirms our previous report that the presence of genitalia spontaneously drawn on a child's drawing of a human figure is associated with alleged sexual abuse. PMID:2329432

    While a number of factors have been linked with excessive anxiety (e.g., parenting, child temperament), the impact of stressful life events remains under-studied. Moreover, much of this literature has examined bivariate associations rather than testing more complex theoretical models. The current study extends the literature on life events and child anxiety by testing a theory-driven meditational model. Specifically, one child factor (child cognitions/locus of control), two parent factors (parent psychopathology and parenting stress), and two parent-child relationship factors (parent-child dysfunctional interaction and parenting style) were examined as mediators in the relationship between stressful life events and severity of child anxiety. One hundred and thirty anxious parents and their nonanxious, high-risk children (ages ranged from 7 to 13 years) participated in this study. Results indicated that levels of parenting stress, parental anxious rearing, and dysfunctional parent-child interaction mediated the association between stressful life events and severity of anxiety symptoms. Child cognition and parent psychopathology factors failed to emerge as mediators. Findings provide support for more complex theoretical models linking life events and child anxiety and suggest potential targets of intervention.

  1. Validation of a new larval rearing unit for Aedes albopictus (Diptera: Culicidae mass rearing.

    Directory of Open Access Journals (Sweden)

    Fabrizio Balestrino

    Full Text Available The mosquito larval rearing unit developed at the Insect Pest Control Laboratory (IPCL of the FAO/IAEA Joint Division was evaluated for its potential use for Aedes albopictus (Skuse, 1895 mass rearing in support of the development of a sterile insect technique (SIT package for this species. The use of the mass rearing trays and rack did not adversely affect larval development, pupation and survival rates and allowed the management of large larval rearing colonies with reduced space requirements in comparison with classical individual trays. The effects of larval density, water temperature and diet composition on pupal production and size differentiation for sex separation efficacy were analyzed for individual mass rearing trays as well as multiple trays stacked within the dedicated rack unit. Best results were obtained using eighteen thousand larvae per tray at a density of 3 larvae per ml of deionized water at a temperature of 28°C on a diet consisting of 50% tuna meal, 36% bovine liver powder, 14% brewer's yeast and, as an additive, 0.2 gr of Vitamin Mix per 100 ml of diet solution. Pupae were harvested on the sixth day from larval introduction at L1 stage and males were separated out by the use of a 1400 µm sieve with 99.0% accuracy with a recovery rate of ca. 25% of the total available males. With the use of this larval rearing unit, an average production of 100,000 male pupae per week can be achieved in just 2 square meter of laboratory space. Compared to previous laboratory rearing method, the same pupal production and sex separation efficacy could only be achieved by use of ca. 200 plastic trays which required the space of two 5 square meter climatic-controlled rooms.

  4. Genetic quality control in mass-reared melon flies

    International Nuclear Information System (INIS)

    Quality control in mass-reared melon flies, Bactrocera cucurbitae, after eradication is discussed, based on the results of artificial selection experiments. First, a brief history of quality control in mass-rearing of insects is described. In practical mass- rearing of melon fly, many traits have already been differentiated between mass-reared and wild flies. These differing traits are reviewed and the factors which caused these differences are considered. It was considered that the differences between wild and mass-reared melon flies depended on the selection pressures from the mass-rearing method. Next, the results of several artificial selection experiments using the melon fly are reviewed. Finally, consideration is given to some correlated responses to artificial selection in mass-rearing. Longevity that is correlated to early fecundity was successfully controlled by artificial selection for reproduction in the mass-rearing system. On the basis of these results, an improved method for quality control in mass-reared melon fly with considerations for quantitative genetics is discussed

    2016-08-01

    This study used US National Longitudinal Study of Youth data to explore how exposure to different socioeconomic conditions (proxied by maternal education) before birth can shape child weight. Using endogenous selection regression models, the findings suggest that educational selectivity affects weight gain. Mothers whose mothers graduated from high school were more likely to complete high school, and mothers reared in an intact family had higher levels of education. However, mothers who had given birth as a teenager had the same educational outcomes as mothers who gave birth in their post-teenage years. Based on this intergenerational educational selectivity, caretaking (e.g. breast-feeding) was found to be associated with a lower child body mass index (BMI), while negative maternal characteristics (e.g. mothers with high BMIs) were associated with higher child BMIs. Thus, educational selectivity influences child health through values passed on to the child and the lifestyle in which the child is reared. Maternal education may be tied to parenting, which relates to child obesity risk. PMID:26314353

  8. A filter rearing system for mass reared genetic sexing strains of Mediterranean fruit fly (Diptera: Tephritidae)

    International Nuclear Information System (INIS)

    The Mediterranean fruit fly (Medfly), Ceratitis capitata (Wied.), is arguably the world's most widespread pest of fresh fruit production. With mounting controversy over using chemicals against insect pests, the sterile insect technique (SIT) has become increasingly more important as a successful technology in controlling or eradicating many insect pests. However, the wider adoption of SIT for Medflies has been hindered by damage to fruit from sterile female stings (Hendrichs et al. 1995). Moreover, the release of sterile females in SIT for Medflies is not efficacious (Hendrichs et al. 1995), a point validated in the field in Hawaii (McInnis et al. 1994) and Guatemala (Rendon, personal communication). Hendrichs et al. (1995) list many other advantages for releasing only male Medflies including improved economy, increased safety and improved field monitoring. Genetic systems for the separation of sexes have been developed for Medflies (Franz and Kerremans 1994, Willhoeft et al. 1996) and they allow for large-scale releases of only males. Genetic sexing strains (GSS), as they are known, are based upon selectable characters linked to the male sex by using a Y-autosome translocation (Franz et al. 1996). There are two types of GSS used in mass rearing. First, strains based upon a recessive mutation (wp) change the pupal colour from brown to white. In these strains, females emerge from white pupae and males from brown pupae. A machine is used to sort the pupae based upon colour. First described by Robinson and Van Heemert (1982), the most recent strain, SEIB 6-96 based upon the T(Y;5) 2-22 translocation, is relatively stable in small scale rearing (Franz et al. 1994). Second are the temperature sensitive lethal strains (wp/tsl) which carry a temperature sensitive lethal (tsl) mutation in addition to wp. In tsl strains, female embryos are killed by exposing eggs to a 3 C temperature during development (Franz et al. 1996). Male embryos are not temperature sensitive and

  14. Child abuse

    International Nuclear Information System (INIS)

    Child abuse is common in most, if not all, Western nations; it probably occurs worldwide. It may be a major factor in the increase in violence throughout much of the world. Radiologists who treat children should think of the possibilitys of abuse whenever they diagnose a fracture, intracranial bleed, ar visceral injury, especially when the history is not compatible with their findings. Metaphyseal 'corner' fractures in infants usually are caused by abuse. Less than 20% of abused children, however, present injuries that can be recognized by radiologic techniques. Consequently normal roentgenograms, nuclear medicine scans, ultrasound studies, and computed tomograms do not exclude child abuse. (orig.)

    Kochanska, G

    1990-12-01

    2 kinds of parental beliefs: endorsed rearing philosophy (authoritative-authoritarian dimension) and affective attitude toward child (positive-negative affect dimension) were examined in 20 normal and 36 depressed mothers as long-term predictors of their rearing behaviors and interaction patterns with their children, and of their ratings of child externalizing problems (Achenbach CBCL). The beliefs were measured when the children were toddlers (Time 1), and maternal behaviors 2-3 years later (Time 2). Mothers' endorsement of the belief in authoritative parenting predicted their frequent avoidance of prohibitive interventions. It also predicted maternal autonomy-granting to the child (more compliant and liberal responses to child-initiated control interventions). Endorsed child-rearing philosophy was a relatively more important predictor of behavior for normal mothers, and affective attitude toward child for the behavior of depressed mothers. Both actual child noncompliance and parental beliefs predicted mothers' ratings of externalizing problems in their children. The former was relatively more important for normal and latter for depressed mothers.

    2010-01-01

    Full Text Available The review starts with the description of the rabbits’ (Oryctolagus cuniculus main habits and the current situation concerning the rabbit husbandry and management systems, as well as their effects on the welfare of these animals. As far as the intensive rabbit husbandry systems are concerned, the main problems are related to the time since rabbits have been domesticated and their adaptive capacity and coping styles as respects the farming environment and management systems. Both these aspects have implications in the present and future of rabbit rearing for different purposes. Examples are given on the effects of different housing and management systems on rabbit welfare, as well as examples of the ethological, physiological and productive indicators used to evaluate these effects. Transportation and, more generally, preslaughter phases including catching, fasting and lairage at the abattoir are considered major stressors for farmed rabbits and might have deleterious effects on health, well-being, performance, and finally, product quality. A general statement of the recent scientific studies considering the effects of pre-slaughter factors on physiological and productive measurements are reported. Finally, some indications in order to improve rabbit welfare, already present at the European level, are also outlined, together with the European Food Safety Authority opinions.

    Full Text Available The camel is one of the typical and the best adopted animals of the desert, capable of enduring thirst and hunger for days and is the most patient of land animals. For desert nomads of Pakistani Cholistan, it is a beloved companion, a source of milk and meat, transport facility provider and a racing/dancing animal, thus, playing an important role in the socioeconomic uplift of the local community. Camels of Marrecha or Mahra breed are mainly used for riding and load carrying but may be trained for dancing or racing. Berella is another heavy and milch breed of camel famous for milk production and can produce upto 10-15 liters of milk per day. This breed is also suitable for draught purpose, though comparatively slow due to heavy body. The present paper also describes the traditional camel rearing system used by nomads of Cholistan desert. Some aspects of camel health, production, feeding, socio-economic values, marketing and some constraints and suggestions are also given so that the policy makers may consider them for the welfare of this animal.

    2016-01-01

    Caring for children should not derail potentially excellent future astronomers. It is therefore suggested that a mechanism be created for established astronomers to voluntarily will 10 percent of their estate to a fund that helps aspiring astronomers reduce child care costs. Statistics indicate that many scientists delay child rearing until they have secure jobs. This delay appears to be based on the early relative cost of child care and the perception that time spent raising children negatively impacts job performance and future employability. Having even a portion of child care expenses covered may increase the efficiency of early-career education and productivity of early-career scientific research. It is hoped that some established astronomers may be inspired to contribute by remembering their own lives as aspiring astronomers, while also wishing to add to their legacy. Only an expression of interest is requested here, both from established astronomers who might be interested in taking such a donation pledge, and from aspiring astronomers who feel their careers would be helped by child care assistance.

    During five years (1939-43) of nutritional research on pen-reared bobwhite quail at the Patuxent Research Refuge, Bowie, Maryland, observations on picking among birds of all ages showed the following results: 1. Picking occurred on all grains tested: corn, wheat, oats, oat groats, barley, millet, buckwheat, kaffir, and mixtures of cereals. The lowest incidence was with buckwheat as the sole grain in a growing diet....2. Picking occurred on all levels of fiber from one to 11per cent in a growing diet....3. Picking occurred on various grinds of corn, barley, and oats, but was least when these cereals were ground in a hammer mill with 3/32 inch mesh screen....4. The incidence was as high on diets containing animal protein as on those containing no animal protein. ....5. After picking began, the addition of one or two per cent of salt to the diet for several days was effective, in many instances, in checking the disorder. Results at the Refuge and the answers to questionnaires from 222 private propagators of gamebirds showed that in two-thirds. of the cases, treatment with an increased quantity of salt successfully stopped the trouble. As a preventative, however, salt was of little value. Picking occurred on both low and high levels of salt.....6. Supplementing the regular diet with certain feed concentrates such as fishmeal, soybean oil meal, liver meal, or chopped greens offered in a separate feeder for a day or two, was as efficacious as the addition of salt.....7. More picking occurred among quail chicks on a 22 per cent level of protein than on higher levels.....8. There was less picking on diets relished by the birds than on those seemingly unpalatable.....9. There was no correlation. between the amount of floor space per chick and the incidence of picking.....10. Increasing the feeding and drinking space seemed to have a marked beneficial effect.....11. Some adult birds on wire floors resorted to self-picking of their feet after the toes were frost-bitten.

    Full Text Available It was suggested that along with genetic factors various psychosocial factors may play a role in the development of Obsessive Compulsive Disorder (OCD. Parents’ childrearing styles and childhood traumatic experiences are among the mostly investigated ones. In literature it was indicated that child rearing styles and childhood traumatic experiences may play a role in the development of OCD. There are studies which show that child rearing styles including excessive protection, critical and rejective are associated with the development of OCD. However, it is still controversial that which child rearing styles lead to the OCD through which mechanisms. Besides, in literature it was shown that emotional traumatic experiences lead to the development of OCD through various factors. In addition, understanding what kind of conflict and problems are reflected by people with OCD diagnosis into the relationship with their children is important in terms of interventions that protect the mental health of the child.

    Chao, Ruth K.

    This study investigated whether certain broad cultural notions, such as "chiao shun" (training children in appropriate behavior or morals) and "guan" (a positive notion expressing parental concern, caring, or involvement) better distinguish the Chinese parent from the European-American than do the concepts of "authoritarian" and "restrictive."…

    The 'Organic' product label guarantees a production process that avoids the use of synthetic fertilisers, pesticides and hormones and minimises recourse to pharmaceuticals or veterinary drugs; however, the product's quality remains an issue that needs to be addressed in response to consumer demand. Consequently, this study was conducted to compare the sensory and nutritional qualities of meat and carcasses from pasture-fed lambs reared organically (O) or conventionally (C). Mean lamb growth profile was kept similar between the two treatments to avoid confounding effects with lamb age or weight at slaughter. The experiment was conducted over 3 years (2005 to 2007) with 12 O and 12 C lambs each year. The O and C treatments differed in the level of on-pasture mineral N fertilisation inducing a higher proportion of white clover in the organic pasture than the conventional pasture. Lambs were slaughtered when they attained a fat class of 2 to 3, and carcass and meat quality were evaluated. Lambs were slaughtered at an average weight and age of 35.3 kg and 156 days in the O treatment, respectively, and 35.2 kg and 155 days in the C treatment, respectively. Sensory evaluation indicated that loin chops from the O treatment had a higher level of abnormal fat odour compared with the C treatment. Carcasses from the O treatment had a softer subcutaneous fat one among 3 years (2007) compared to the C treatment. These results are probably due to a higher proportion of white clover in the diet. Organically reared lambs did offer the slight advantage of muscle fatty acid containing a higher level of stearic acid, which may have positive effects in the prevention of cardiovascular disease in humans. This may be the result of a higher rumen bio-hydrogenation of C18:3n-3 due to differences in the botanical composition between the O and the C pasture. Production system had no effect on the colour characteristics of the meat and subcutaneous fat, except lightness of subcutaneous dorsal

    Newbold, Lindsay K; Oliver, Anna E; Cuthbertson, Leah; Walkington, Sarah E; Gweon, Hyun S; Heard, Matthew S; van der Gast, Christopher J

    2015-08-01

    Bumblebees are ecologically and economically important as pollinators of crop and wild plants, especially in temperate systems. Species, such as the buff-tailed bumblebee (Bombus terrestris), are reared commercially to pollinate high-value crops. Their highly specific gut microbiota, characterized by low diversity, may affect nutrition and immunity and are likely to be important for fitness and colony health. However, little is known about how environmental factors affect bacterial community structure. We analysed the gut microbiota from three groups of worker bumblebees (B. terrestris) from distinct colonies that varied in rearing and foraging characteristics: commercially reared with restricted foraging (RR); commercially reared with outside foraging (RF); and wild-caught workers (W). Contrary to previous studies, which indicate that bacterial communities are highly conserved across workers, we found that RF individuals had an intermediate community structure compared with RR and W types. Further, this was shaped by differences in the abundances of common operational taxonomic units (OTUs) and the diversity of rare OTUs present, which we propose results from an increase in the variety of carbohydrates obtained through foraging.

  11. Rearing history and allostatic load in adult western lowland gorillas (Gorilla gorilla gorilla) in human care.

    Science.gov (United States)

    Edes, Ashley N; Wolfe, Barbara A; Crews, Douglas E

    2016-03-01

    Disrupted rearing history is a psychological and physical stressor for nonhuman primates, potentially resulting in multiple behavioral and physiological changes. As a chronic, soma-wide stressor, altered rearing may be best assessed using a holistic tool such as allostatic load (AL). In humans, AL estimates outcomes of lifetime stress-induced damage. We predicted mother-reared gorillas would have lower AL than nursery-reared and wild-caught conspecifics. We estimated AL for 27 gorillas housed at the Columbus Zoo and Aquarium between 1956 and 2014. AL estimates were calculated using biomarkers obtained during previous anesthetic events. Biomarkers in the high-risk quartile were counted toward a gorilla's AL. Rearing history was categorized as mother-reared, nursery-reared, and wild-caught. Using ANCOVA, rearing history and AL are significantly associated when age and sex are entered as covariates. Wild-caught gorillas have significantly higher AL than mother-reared gorillas. Neither wild-caught nor mother-reared gorillas are significantly different from nursery-reared gorillas. When examined by sex, males of all rearing histories have significantly lower AL than females. We suggest males face few stressors in human care and ill effects of rearing history do not follow. Wild-caught females have significantly higher AL than mother-reared females, but neither is significantly different from nursery-reared females. Combined with our previous work on AL in this group, wherein females had twofold higher AL than males, we suggest females in human care face more stressors than males. Disrupted rearing history may exacerbate effects of these stressors. Providing opportunities for females to choose their distance from males may help reduce their AL.

    2003-04-01

    The comparison of the contents of nutrients determined in commercial hand rearing diets with the nutrient requirements of growing budgerigars and lovebirds estimated by the factorial method revealed satisfactory protein, lysine and arginine concentrations. Regarding sulphur amino acids, a number of products showed marginal methionine and cystine contents. Mineral contents generally met all requirements and were even excessive in some cases. Ultimately, the results gained in this study demonstrate that nestlings' substantial requirements for sulphur amino acids for plumage development are often underestimated, while their calcium requirements in connection with bone mineralization are frequently overestimated. The primary obstacle to successful hand rearing, however, probably lies not so much in energy and nutrient contents, but rather--as revealed by first results of feeding trials with lovebirds--in the passage of the suspended diet through the gastrointestinal tract (e.g. crop disorders) and/or errors regarding feed quantities and feeding frequency.

    Full Text Available The aim of this research was to compare slaughtering traits of two pig genotypes when reared in two different ways, and to determine the influence of pig housing on carcass characteristics and muscle tissue quality. The research was carried out on 68 fattening pigs of both sex, divided into two groups: the first group was kept on deep litter, and the second one was housed in flat deck pens without deep litter. Each group consisted of pigs of two genotypes, i.e. three-way crossbreeds of Large White and German Landrace (LW x GL in the dam line and of German Landrace and Pietrain (P in the sire line. At the end of the experiment, pigs were slaughtered and the following values were determined: the pH45 and pH24 values, electric conductivity values (EC45, EC24, the “a” and “b” carcass length, loin values and the values of backfat and muscle thickness, aiming to evaluate the share of muscular tissue in carcass by applying the two-points method. Pigs reared on deep litter had statistically significantly smaller live weights (P<0.05 and warm carcass weights in comparison to pigs reared on flat deck without deep litter. Pigs crossed with Pietrain, which were kept without deep litter had significantly thicker muscles than the ones crossed with German Landrace, kept on deep litter (P<0.05. Fattening pigs of both genotypes, reared without deep litter, had significantly smaller pH45 values in loins and in MLD, when compared to pigs crossed with Pietrain and kept on deep litter (P<0.05. The influence of genotype was statistically significant for the EC45 value in loin, as well as for the muscle thickness and percentage share of muscular tissue (P<0.05. Interaction between the way of fattening and genotype did not have any effect on carcass and meat quality.

    Small founder populations of whooping cranes are managed to maximize egg production for the purpose of reintroducing young to the wild. This results in an excessive number of hatched chicks that cannot be naturally reared by parents. Hand-rearing techniques have been developed to raise the additional hatches. However, hand rearing may affect the behavior of the birds and their chances of survival later in life. The objectives of this study were to determine the impact of rearing practices on the behavior of whooping crane chicks. The birds were reared under three commonly used rearing techniques: parent reared (PR), hand reared (HR), and hand reared with exercise (HRE). Fifty-six whooping crane chicks were observed by focal animal sampling from hatch to 20 weeks of age. During these observations, occurrences of comfort behavior, aggression, foraging, nonvigilance, sleep, vigilance, and other types of behavior were collected. Data were analyzed using mixed models repeated measures analysis of variance (ANOVA). Behavior was affected by rearing treatment, age, and time of day. PR birds spent more time being vigilant than HR and HRE birds. An inverse correlation was found between percentage of time foraging and vigilant (r = -0.686, P < 0.0001). However, there were no differences in the behavior of birds reared in HR or HRE programs.

  7. Factors related to seatbelt-wearing among rear-seat passengers in Malaysia.

    The benefit of wearing a rear seatbelt in reducing the risk of motor vehicle crash-related fatalities and injuries has been well documented in previous studies. Wearing a seatbelt not only reduces the risk of injury to rear-seat passengers, but also reduces the risk of injury to front-seat occupant who could be crushed by unbelted rear-seat passengers in a motor vehicle crash. Despite the benefits of wearing a rear seatbelt, its rate of use in Malaysia is generally low. The objective of this study was to identify factors that are associated with the wearing of a seatbelt among rear-seat passengers in Malaysia. Multinomial logistic regression analysis of the results of a questionnaire survey of 1651 rear-seat passengers revealed that rear-seat passengers who were younger, male, single and less educated and who had a perception of a low level of legislation enforcement, a lower risk-aversion and less driving experience (only for passengers who are also drivers) were less likely to wear a rear seatbelt. There was also a significant positive correlation between driver seatbelt and rear seatbelt-wearing behaviour. This implies that, in regards to seatbelt-wearing behaviour, drivers are more likely to adopt the same seatbelt-wearing behaviour when travelling as rear-seat passengers as they do when driving. These findings are crucial to the development of new interventions to increase the compliance rate of wearing a rear seatbelt. PMID:22633252

In particular, the belief that child abuse determination is obvious. However, this assumption fails to make a distinction between nineteenth century’s emphasis on impoverished environments and the twentieth century introduction of the pathological child abuser. Moreover, the proliferation of kinds of child abuse, and the need to distinguish child abusers from non-abusers, means knowledge is now spread across an array of disciplines and professions, which necessarily destabilizes the definition of child abuse. The increasing exposure of alternate care systems as potentially abusive has similarly destabilized the old common sense solution to neglected children—namely removal. Finally, as uncertainty increases, and definitions become more divergent, the question of what child abuse is, and what should be done about it, becomes increasingly politicized.

  13. Experience and geometry: controlled-rearing studies with chicks.

    2010-05-01

    Animals can reorient making use of the geometric shape of an environment, i.e., using sense and metric properties of surfaces. Animals reared soon after birth either in circular or in rectangular enclosures (and thus affording different experiences with metric properties of the spatial layout) showed similar abilities when tested for spatial reorientation in a rectangular enclosure. Thus, early experience in environments with different geometric characteristics does not seem to affect animals' ability to reorient using sense and metric information. However, some results seem to suggest that when geometric and non-geometric information are set in conflict, rearing experience could affect the relative dominance of featural (landmark) and geometric information. In three separate experiments, newborn chicks reared either in circular- or in rectangular-shaped home-cages were tested for spatial reorientation in a rectangular enclosure, with featural information provided either by panels at the corners or by a blue-coloured wall. At test, when faced with affine transformations in the arrangement of featural information that contrasted with the geometric information, chicks showed no evidence of any effect of early experience on their relative use of geometric and featural information for spatial reorientation. These findings suggest that, at least for this highly precocial species, the ability to deal with geometry seems to depend more on predisposed mechanisms than on learning and experience after hatching.

  14. Managing Ammonia Emissions From Screwworm Larval Rearing Media.

    2016-02-01

    Mass production, sterilization, and release of screwworms (Cochliomyia hominivorax (Coquerel)) that were competitive in the field significantly contributed to the successful application of the sterile insect technique for eradication of screwworms from continental North America. Metabolic byproducts resulting from protein-rich diets required for larval screwworms lead to ammonia liberation, sometimes at high levels, within the mass rearing facility. Until recently a sodium polyacrylate gel bulking agent was used for the larval media and adsorbed much of the ammonia. A need to replace the gel with an environmentally "friendly" bulking agent, while not increasing ammonia levels in the rearing facility, led to a series of experiments with the objective of developing procedures to reduce ammonia emissions from the larval media bulked with cellulose fiber. Additives of ammonia-converting bacteria, potassium permanganate, and Yucca schidigera Roezl ex Otrgies powder extract, previously reported to reduce ammonia levels in organic environments, were evaluated. Ammonia-converting bacteria did not have a positive effect. Addition of Y. schidigera powder extract (∼1% of total volume), potassium permanganate (∼250 ppm), and a combination of these two additives (at these same concentrations) kept ammonia at equivalent levels as when larval media was bulked with gel. Potassium permanganate also had sufficient antimicrobial properties that the use of formaldehyde in the diet was not necessary. Further testing is needed, at a mass rearing level, before full implementation into the screwworm eradication program.

  15. Resting Behaviour of Broilers in Three Different Rearing Systems

    2003-09-01

    Full Text Available The highest number of broilers is reared in the intensive fattening system on the floor with litter. Besides the intensive systems some sustainable rearing ways are also brought forward (ecological, biologic-dynamic, organic, etc.. The aim of this study was to establish the possible differences in resting behaviour of broilers in three rearing systems: intensive on the floor, free range, and organic system. The results showed great varieties between intensive and less intensive systems. In the intensive system on the floor animals rested statistically highly significantly more than in other two systems. However no differences in the behaviour of broilers in the stall were noticed, ifcompared to broilers in free range and those in the organic system. Comparison of the outdoor area showed that broilers rested statistically significantly more in the organic system. The reasons for different resting behaviour could be in leg weakness, body weight, group size, health problems, age, housing system, etc. Our research did not confirm our hypothesis that the older broilers rest more.

    Mass production, sterilization, and release of screwworms (Cochliomyia hominivorax (Coquerel)) that were competitive in the field significantly contributed to the successful application of the sterile insect technique for eradication of screwworms from continental North America. Metabolic byproducts resulting from protein-rich diets required for larval screwworms lead to ammonia liberation, sometimes at high levels, within the mass rearing facility. Until recently a sodium polyacrylate gel bulking agent was used for the larval media and adsorbed much of the ammonia. A need to replace the gel with an environmentally "friendly" bulking agent, while not increasing ammonia levels in the rearing facility, led to a series of experiments with the objective of developing procedures to reduce ammonia emissions from the larval media bulked with cellulose fiber. Additives of ammonia-converting bacteria, potassium permanganate, and Yucca schidigera Roezl ex Otrgies powder extract, previously reported to reduce ammonia levels in organic environments, were evaluated. Ammonia-converting bacteria did not have a positive effect. Addition of Y. schidigera powder extract (∼1% of total volume), potassium permanganate (∼250 ppm), and a combination of these two additives (at these same concentrations) kept ammonia at equivalent levels as when larval media was bulked with gel. Potassium permanganate also had sufficient antimicrobial properties that the use of formaldehyde in the diet was not necessary. Further testing is needed, at a mass rearing level, before full implementation into the screwworm eradication program. PMID:26468514

    Child care subsidies are an important part of federal and state efforts to move welfare recipients into employment. One of the criticisms of the current subsidy system, however, is that it overemphasizes work and does little to encourage parents to purchase high-quality child care. Consequently, there are reasons to be concerned about the…

  18. Child-to-Child programme in Malaysia.

    Even though Malaysia is a relatively prosperous country amongst the developing nations, it is still be set by problems of a rapidly increasing population. The economic cake is also unevenly distributed and there are pockets of poverty in the slums surrounding the towns as well as in the rural areas. Added to that is the problem of ignorance and superstition especially amongst its adult population. It is due to these problems that the Child-to-Child programme has found special application in Malaysia. The Child-to-Child has been introduced through either the government agencies or the voluntary organizations. Through the Ministry of Education, the concept has found its ways through the schools and the state department of education. The Ministry of Information and Broadcasting has also introduced the concept of Child-to-Child in the media. The voluntary organizations have also introduced the concept of Child-to-Child in their projects. The Sang Kancil project has to some extent used the idea in the running of its activities. The Health and Nutrition Education House have found that by applying the concept and using older children to help in running its activities, its over all objective which is the improvement of the health of the children in the slums could be reached more easily.

  19. What makes a child a 'competent' child?

    2015-12-01

    Competence is a vital component of the informed consent process. The perceived level of a child's competence may influence their degree of participation in health decisions that affect them. It is the responsibility of the health professional to gauge a child's level of competence. Child competence, however, is not a static attribute that is linked to age. Rather, it is dynamic, changing in nature and dependent on a child's previous experiences, personal attributes, network of relationships around them and cultural and environmental context. Consequently, there is no single verified assessment tool to assist in the recognition of competence for New Zealand children. Adding to this complexity are the unclear interpretations of New Zealand health legislation and policy regarding whether or not a child can legally consent or refuse healthcare advice and treatment without the consent of a legal guardian. Under the Care of Children Act 2004 and the Code of Health and Disability Services Consumers' Rights 1996, the Health and Disability Commissioner states "a child may consent themselves [to health treatment] if and when the child achieves sufficient understanding and maturity to understand fully what is proposed". This paper poses the question: What is 'competency' and how is this decided? For the purpose of this article, 'child' pertains to those under the age of 16 years. PMID:26913912

    The fostering of an autistic child deemed to be a child at risk leads one to question one's professional practices. In a children's home, an approach guided by psychoanalysis can recognise the benefits of behavioural or cognitive approaches. The aim of the professional's particular educational position is therefore to construct a relationship with each child.

  5. From child to child: children as communicators.

    Science.gov (United States)

    Phinney, R; Evans, J

    1993-01-01

    Older children commonly care for their younger siblings while parents work to provide for the household. Through play, dance, and talk, children tend to interact with each other more intensely than do adults. In so doing, messages and awareness are exchanged more effectively. Child-to-Child is an active, child-centered learning approach which aims to capitalize on this phenomenon by training older siblings to be effective communicators. This approach has been formally practiced in over 70 countries since 1979. Child-to-Child encourages children to learn the meaning and importance of health messages on their own. Children will then be most likely to retain and communicate information throughout the family, to neighbors, and to the general community. No blueprint exists, however, on which program planners may base the design of new programs. Programs should instead be adapted by those living within the community and culture to fit local needs and circumstances. Nonetheless, the Aga Khan Foundation supported the study of 7 highly different Child-to-Child projects over 3 years in India to obtain some sense of which program elements are successful and potentially useful in other settings. The study revealed that all of the programs helped increase the health knowledge of children and teachers. Little information was obtained on the extent to which information was diffused by children within the community. Overall, the study produced the following results: planners should consider using Child-to-Child projects in schools; teacher training should be made a priority; administrative support should be provided; entire staffs should be made to feel involved in the decision making process; obstacles to changing teaching methods should not be underestimated; teaching materials should be locally made; projects should be integrated into official curricula; program topics should be relevant to local realities; respected authorities should be called upon to reinforce the validity

    Spodoptera cosmioides (Walker) (Lepidoptera: Noctuidae) is a polyphagous pest that threatens more than 24 species of crop plants including those used for biodiesel production such as Ricinus communis (castor bean), Jatropha curcas (Barbados nut), and Aleurites fordii (tung oil tree). The development and leaf consumption by S. cosmioides reared on leaves of these three species were studied under controlled laboratory conditions. The egg-to-adult development time of S. cosmioides was shortest when reared on castor bean leaves and longest when reared on tung oil tree leaves. Larvae reared on castor bean and Barbados nut leaves had seven instars, whereas those reared on tung oil tree leaves had eight. Females originating from larvae reared on castor bean and Barbados nut leaves showed greater fecundity than did females originating from larvae reared on tung oil tree leaves. Insects fed on castor bean leaves had shorter life spans than those fed on tung oil tree and Barbados nut leaves although the oviposition period did not differ significantly. The intrinsic and finite rates of increase were highest for females reared on castor bean leaves. Total leaf consumption was highest for larvae reared on tung oil tree leaves and lowest for those reared on Barbados nut leaves. We conclude that castor bean is a more appropriate host plant for the development of S. cosmioides than are Barbados nut and tung oil tree. PMID:27193276

    This study characterizes pediatric wheelchair kinematic responses and wheelchair tiedown and occupant restraint system (WTORS) loading during rear impact. It also examines the kinematic and loading effects of wheelchair headrest inclusion in rear impact. In two separate rear-impact test scenarios, identical WC19-compliant manual pediatric wheelchairs were tested using a seated Hybrid III 6-year-old anthropomorphic test device (ATD) to evaluate wheelchair kinematics and WTORS loading. Three wheelchairs included no headrests, and three were equipped with slightly modified wheelchair-mounted headrests. Surrogate WTORS properly secured the wheelchairs; three-point occupant restraints properly restrained the ATD. All tests used a 26km/h, 11g rear-impact test pulse. Headrest presence affected wheelchair kinematics and WTORS loading; headrest-equipped wheelchairs had greater mean seatback deflections, mean peak front and rear tiedown loads and decreased mean lap belt loads. Rear-impact tiedown loads differed from previously measured loads in frontal impact, with comparable tiedown load levels reversed in frontal and rear impacts. The front tiedowns in rear impact had the highest mean peak loads despite lower rear-impact severity. These outcomes have implications for wheelchair and tiedown design, highlighting the need for all four tiedowns to have an equally robust design, and have implications in the development of rear-impact wheelchair transportation safety standards.

    Full Text Available New method for rearing Spodoptera frugiperda in laboratory shows that larval cannibalism is not obligatory. Here we show, for the first time, that larvae of the fall armyworm (FAW, Spodoptera frugiperda (Lepidoptera, Noctuidae, can be successfully reared in a cohort-based manner with virtually no cannibalism. FAW larvae were reared since the second instar to pupation in rectangular plastic containers containing 40 individuals with a surprisingly ca. 90% larval survivorship. Adult females from the cohort-based method showed fecundity similar to that already reported on literature for larvae reared individually, and fertility higher than 99%, with the advantage of combining economy of time, space and material resources. These findings suggest that the factors affecting cannibalism of FAW larvae in laboratory rearings need to be reevaluated, whilst the new technique also show potential to increase the efficiency of both small and mass FAW rearings.

    In vitro rearing is an important and useful tool for honey bee (Apis mellifera L.) studies. However, it often results in intercastes between queens and workers, which are normally are not seen in hive-reared bees, except when larvae older than three days are grafted for queen rearing. Morphological classification (queen versus worker or intercastes) of bees produced by this method can be subjective and generally depends on size differences. Here, we propose an alternative method for caste cla...

    Full Text Available The objective of this work was to compare the morphometry of hatchery-reared and wild-caught mangrove crab (Ucides cordatus megalopae. Ten U. cordatus megalopae of each group (hatchery-reared and wild-caught were individually analyzed using a stereoscopic microscope equipped with an ocular micrometer. Length, width, and height of all megalopae were measured, and the size of body appendices was determined. The results indicate that the hatchery-reared megalopae are more robust than the wild ones. Furthermore, some significant differences in the size of certain appendices can be cues of the kind of alterations that hatchery-reared individuals experience.

    Full Text Available Proper securement of wheelchairs in motor vehicles is vital to providing wheelchair users an adequate level of safety in a crash. Thus far, wheelchair tiedown and occupant restraint systems (WTORS loading has mostly been examined under frontal impact conditions. Because of the inherent crash dynamic differences, rear-impact loading of WTORS is expected to differ greatly. In this study, three identical, reinforced, manual, folding, X-braced ANSI/RESNA WC19 wheelchairs were subjected to an International Organization for Standardization-proposed rear-impact crash pulse. WTORS loads (front tiedowns, rear tiedowns, lap belt, and shoulder belt were measured and compared with frontal impact WTORS loading. Rear impact produced substantially higher loads (up to 7,851 N in the front tiedowns than frontal impact. The rear tiedowns experienced relatively negligible loading (up to 257 N in rear impact, while rear-impact dynamics caused the lap belt (maximum load of 1,865 N to be loaded substantially more than the shoulder belt (maximum load of 68 N. Considering differences in frontal and rear impact WTORS loading is important to proper WTORS design and, thus, protection of wheelchair-seated occupants subjected to rear-impact events.

    2002-07-01

    The black soldier fly, Heretia illucens (L.), is a nonpest tropical and warm-temperate region insect that is useful for managing large concentrations of animal manure and other biosolids. Manure management relying on wild fly oviposition has been successful in several studies. However, confidence in this robust natural system was low and biological studies were hampered by the lack of a dependable source of eggs and larvae. Larvae had been reared easily by earlier investigators, but achieving mating had been problematic. We achieved mating reliably in a 2 by 2 by 4-m screen cage in a 7 by 9 by 5-m greenhouse where sunlight and adequate space for aerial mating were available. Mating occurred during the shortest days of winter if the sun was not obscured by clouds. Adults were provided with water, but no food was required. Techniques for egg collection and larval rearing are given. Larvae were fed a moist mixture of wheat bran, corn meal, and alfalfa meal. This culture has been maintained for 3 yr. Maintainance of a black soldier fly laboratory colony will allow for development of manure management systems in fully enclosed animal housing and in colder regions. PMID:12144307

The genetic distance be-tween the two stocks was 0.0041. From the comprehensive investigation, the main reasons for the loss of genetic diversity were probably overilshing, small number of parents as broodstocks and the debatable arti-ficial ranching. Results from this study also showed that the large yellow croaker populations distributed along Fujian coastal waters including Guan-Jing-Yang still potentially wide genetic variability. It is sug-gested that genetic management and prevention should be scientifically conducted in order to maintain and improve the genetic diversity of the P. crocea population.

    Objective: To carry out an experimental study with the main objective of mass rearing of sheep flies (Lucilia sericata). Methods: Hand collection and beef- or cattle liver-baited net traps were used for field fly sampling from April, 2010 to November, 2010. The samples collected from different places were placed in properly labeled tubes and sent to the Entomology Laboratory. Since maggot identification is important in inducing mortality, they were kept under insectary condition to develop to adult stage and identified using systematic keys. Results: A total of 218 flies were collected in three rounds of sampling from the field of Tehran and Karaj Counties. In the first generation, 433 flies including 135 (31.17%) male, and 298 (68.82%) female were yielded. The female/male of parent ratio was calculated as 1.72 in Tehran and in Karaj areas, whereas it was 2.20% and 1.81%, respectively in F1 and F2 generations, respectively. Conclusions: During this study, the mass rearing of sheep blow fly has been established at the School of Public Health, Tehran University of Medical Sciences and can be used for producing flies for maggot therapy.

This splitting of human life-supporting activities has sealed women's dependence on men by setting off the lucrative area from the private, non-lucrative sphere of activities. These contradictions become paradoxical as soon as we consider the delegation of responsibility for the care of a child to someone not related to the child. This article addresses the question of how the child's developmental needs can be met without damage to his/her sensitivity, and his/her perception of others or of the cooperation involved. As soon as it is born, the child, a thoroughly interactive being, discerns the relationships it entertains with those who are in charge of him/her. The persons - mostly women - who take care of the child are not interchangeable, since they bring their own subjectivity into their dealings with the child and this is reciprocal. The women's skills, frequently thought to be “undefinable”, but which many women, whether related or not to the child, have developed or should develop, are brought into play and are either transmitted or acquired in the course of their care of the child; these skills are not by nature “feminine skills”, but they require a great deal of reactivity and sensitivity and therefore, many child professionals, mothers' aids and children's care-takers in the home are hurt and insulted by the low esteem in which they are held. These skills and human qualities, which are the result of feelings more than of formalised knowledge, techniques or theories - albeit these are also necessary - make child care and child rearing an art. These skills seem to be in total contradiction with those that are current in the world of labour, where the tempo of work, flexibility of working

    We quantified the aggression, feeding, dominance, position choice, and territory size of naturally reared steelhead Oncorhynchus mykiss fry stocked with two types of hatchery-reared fry (from conventional and enriched rearing environments) at two densities in experimental flumes to determine how rearing environment and fish density affect the behavior of steelhead fry. We found that fry density had a significant effect on most response variables but that rearing treatment did not. The rates of threats and attacks were positively correlated with fry density, but the overall feeding rate was negatively correlated. Naturally reared fry were dominant more often at low densities, and hatchery-reared fry were dominant more often at high densities. There were no significant effects of hatchery rearing treatment on aggression, feeding, dominance, or territory size. The only significant effect of rearing treatment was on the position of naturally reared fry, which occupied more upstream positions when stocked with conventional than with enriched hatchery-reared fry. Overall, rearing environment had relatively little influence on the behavior of steelhead fry. Our results indicate that stocking hatchery-reared steelhead fry at low densities may have effects on similar-size wild fish comparable to an equivalent increase in the density of wild fish. We suggest that releasing hatchery-reared steelhead fry as a supplementation strategy may have few direct negative ecological effects on wild fry.

  15. Development of a Natural Rearing System to Improve Supplemental Fish Quality, 1999-2003 Progress Report.

    Energy Technology Data Exchange (ETDEWEB)

    Maynard, Desmond J.

    2003-02-25

    The National Marine Fisheries Service (NMFS) has been conducting Natural Rearing Enhancement System (NATURES) research since the early 1990s. NATURES studies have looked at a variety of mechanisms to enhance production of wild-like salmonids from hatcheries. The goal of NATURES research is to develop fish culture techniques that enable hatcheries to produce salmon with more wild-like characteristics and increased postrelease survival. The development of such techniques is called for in the Columbia Basin Fish and Wildlife Program. This document is the draft report for the Supplemental Fish Quality Contract DE-AI79-91BP20651 Over the history of the project, the effects of seminatural raceway habitats, automated underwater feeders, exercise current velocities, live food diets, and predator avoidance training have been investigated. The findings of these studies are reported in an earlier contract report (Maynard et al. 1996a). The current report focuses on research that has been conducted between 1999 and 2002. This includes studies on the effect of exercise on salmon and steelhead trout, effects of predator avoid training, integration of NATUES protocols into production hatcheries, and the study of social behavior of steelhead grown in enriched and conventional environments. Traditionally, salmon (Oncorhynchus spp.) are reared in barren concrete raceways that lack natural substrate, in-stream structure, or overhead cover. The fish are fed in an unnatural manner with artificial feeds mechanically or hand broadcast across the water surface. This traditional approach has increased the egg-to-smolt survival of hatchery-reared fish by an order of magnitude over that experienced by wild-reared salmon. However, once hatchery-reared fish are released into the wild their smolt-to-adult survival is usually much lower than wild-reared salmon. The reduced postrelease survival of hatchery-reared fish may stem from differences in their behavior and morphology compared to wild-reared

  8. The battered child syndrome

    International Nuclear Information System (INIS)

    The recognition of a battered child represents a challenge for all groups of adults dealing with children. Radiology plays a special role in this setting. By detection typical injuries, imaging is able to confirm the suspicion of a battered child. Recognition of those injuries on films, taken for other reasons, gives the caretaker an important hint, thus maybe preventing a fatal outcome for the child. One of the most important injury types is represented by the so called ''shakin baby syndrome''. The infant is held by the thorax and shaken. Thus causing a repetitive acceleration-deceleration trauma, which leads to the typical paravertebral rib fractures, intracranial bleeding and eye injuries. After shaking the child is thrown away, with subsequent injuries. The aim of this article is the presentation of an overview regarding the radiology of the battered child. Typical examples will be shown. (orig.)

    Child prostitution is an old, global and complex phenomenon, which deprives children of their childhood, human rights and dignity. Child prostitution can be seen as the commercial sexual exploitation of children involving an element of forced labour, and thus can be considered as a contemporary form of slavery. Globally, child prostitution is reported to be a common problem in Central and South America and Asia. Of all the south-east Asian nations, the problem is most prolific in Thailand. In Thailand, there appears to be a long history of child prostitution, and this article explores the factors that underpin the Thai child sex industry and the lessons and implications that can be drawn for health care and nursing around the world.

    Appropriate rearing is essential for ensuring the welfare and productivity of laying hens. Early experience has the potential to affect the development of fearfulness. This study tested whether rearing in aviaries, as opposed to cages, reduces the fearfulness of laying hens after transfer to furnished cages. Fear responses were recorded as avoidance of a novel object in the home cage. Lohmann Selected Leghorns were reared in an aviary system or conventional rearing cages and then transported to furnished cages at 16 weeks, before the onset of lay. Observations of a selection of birds were conducted at 19 (N = 50 independent cages) and 21 (N = 48 independent cages) weeks of age. At 19 and 21 weeks, cage-reared birds showed higher levels of fearfulness indicated by spending more time away from the novel object compared to aviary-reared birds. These results suggest that rearing in an enriched aviary environment reduces fearfulness up to the fifth week after transfer to a new housing system, compared to rearing in cages. PMID:26955634

    1998-02-01

    In this study, the effect of genetic constitution (stock) and rearing temperature on the occurrence of hemorrhages in thighs and breasts of water bath stunned broilers was investigated. Particular attention was given to the relation between the susceptibility for hemorrhages, body composition, and adaptations in blood variables induced by low rearing temperatures. A factorial experiment was performed with five parental stocks, differing with respect to growth rate, feed conversion, and body composition, and two temperature regimens (thermoneutral and below the zone of thermoneutrality). Hemorrhage scores in thighs were dependent on rearing temperature, not on stock, and were highest in broilers reared at low temperatures. In all stocks, high scores in the thighs were accompanied by an increased carbon dioxide pressure and bicarbonate and triiodothyronine concentration of the venous blood, and by an increased relative heart weight, hematocrit, and blood loss at slaughter. Hemorrhage scores in breasts were dependent on stock, confounded with day of scoring. An effect of rearing temperature was present only for the leanest, slow-growing stock having the lowest feed conversion ratio at thermoneutral rearing conditions. Scores in breasts were related neither to body composition nor to metabolic and hemodynamic adaptations to low rearing temperatures. It is concluded that high hemorrhage scores in thighs are related to hemodynamic and metabolic adaptations to an increased need for energy and oxygen caused by low rearing temperatures. Hemorrhage scores are not related to stock-dependent differences. PMID:9495502

The crop fungi of attine fungus-growing ants are suspected to have enhanced genetic variation reminiscent of polyploidy, but this has never been quantified with cytological data and genetic markers. We estimated...... the number of nuclei per fungal cell for 42 symbionts reared by 14 species of Panamanian fungus-growing ants. This showed that domesticated symbionts of higher attine ants are polykaryotic with 7-17 nuclei per cell, whereas nonspecialized crops of lower attines are dikaryotic similar to most free......-living basidiomycete fungi. We then investigated how putative higher genetic diversity is distributed across polykaryotic mycelia, using microsatellite loci and evaluating models assuming that all nuclei are either heterogeneously haploid or homogeneously polyploid.

  3. Dairy Heifer Rearing in Hot Arid Zone: An Economic Assessment

    Directory of Open Access Journals (Sweden)

    M. A. Razzaque

    2010-01-01

    Full Text Available Problem statement: Economic losses due to high mortality in young calves born in hot arid zone including Kuwait and a high cost of rearing are the main constraints to this region. Therefore, dairy producers have to depend on importation of pregnant heifers for herd replacement. Research data on cost of heifer rearing from their weaning to first lactation were lacking. The objectives of the present investigation were to compare the costs/benefits of raising heifers born in Kuwait without and with intervention measures and project the future financial benefits. Approach: Present study methods involved using cost-benefit model where without and with intervention scenarios were compared using a total of 58 herd parameters. These variables included in the spreadsheets in the model could be varied during each year of projection period. Production turnoff of 3 herds each of 245 cows in three scenarios namely baseline, improved and future were evaluated. Input costs of imported heifers (baseline, locally raised heifers with interventions (improved and projected 10 year (future and the income generated from these scenarios were analyzed. Results: Total income generated from baseline, improved and the future projection were KD 268,715/-, 281,246/-and 342,251/-respectively (1 KD Kuwaiti Dinar = US $3.45; total operating costs of these scenarios were KD 249,372/-, 242,276/-and 205,929/-respectively. Financial analyses showed that benefits were double when interventions were applied KD 19,343/-Vs KD 38,970/-in baseline and improved operation respectively. Conclusion: Fifty percent of the total heifers needed for herd replacement could be sourced locally showing an increased net income as an outcome of intervention measures. Locally born adapted heifers could be used for dairying in this hot arid zone with a phase-wise increase in their herd size reducing dependence on imported dairy cattle.

  4. Alternative diets for maintaining and rearing cephalopods in captivity.

    1989-07-01

    The requirement of live marine prey for cephalopod mariculture has restricted its practicality for inland research laboratories, commercial enterprises and home aquarists. We evaluated acceptability and resultant growth on: (a) frozen marine shrimps, (b) live and frozen marine polychaete worms, (c) live and frozen marine crabs, (d) frozen marine fishes, (e) live adult brine shrimp, (f) live freshwater fish and (g) live freshwater crayfish. The diets were presented for periods of 2 to 11 weeks to octopuses, cuttlefishes or squids and in most trials the results were compared to animals fed control diets of live marine shrimps, crabs or fish. Overall, frozen marine shrimp proved to be the best alternative diet tested. Adult Octopus maya on frozen marine shrimp diets grew as well as those on control diets at 2.8% body weight per day (%/d) compared to 2.0%/d on live freshwater crayfish, 1.4%/d on live marine polychaete worms and 0.8%/d on live freshwater fish (Tilapia sp.). Juvenile Octopus maya and Octopus bimaculoides also grew comparably to controls when fed frozen marine shrimps; growth rates ranged from near 3.0%/d at 3 months of age to nearly 2.5%/d at 6 months of age. Thus, these alternatives are acceptable as the octopuses end their exponential growth phase at an age of 3 - 5 months. Attempts to rear O. maya hatchlings and juveniles (up to 1 month of age) on dead foods resulted in high mortality and slow or negative growth. No live or dead alternative diet has been found yet that will promote good growth and survival in hatchling octopuses. Hatchling F3 generation Sepia officinalis (the European cuttlefish) were reared for 6 weeks exclusively on adult brine shrimp (Artemia salina).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2761235

    Full Text Available The study was conducted to evaluate the influence of the rearing system on the muscle fibre characteristics of two meat chicken breeds such as the Ross and the Livorno characterized by extremely fast and extremely slow growth speed respectively. No differences between the breeds were found in the conventional rearing system except for muscle fibre area. On the other hand, in the free range rearing system, differences in muscle fibre composition were evidenced between the breeds especially in the Ileotibialis lateralis muscle with the Livorno having a greater percentage of αR fibres (57,71 vs 36,65. A higher percentage of αR fibres (57,71 vs 46,90 was found in the Ileotibialis lateralis of the free range reared Livorno chickens compared to the conventionally reared ones.

    The National Marine Fisheries Service (NMFS), in cooperation with Idaho and BPA, has established captive broodstocks to aid recovery of endangered Snake River sockeye salmon. NMFS is currently maintaining four separate Redfish Lake sockeye Salmon captive broodstocks; all these broodstocks are being reared full-term to maturity in fresh (well) water. Experiments are also being conducted on nonendangered 1990 and 1991-brood Lake Wenatchee (WA) sockeye salmon to compare effects on survival and reproduction to maturity in fresh water and seawater; for both brood-years, fish reared in fresh water were larger than those reared in seawater. Data from captive rearing experiments suggest a ranking priority of circular tanks supplied with pathogen-free fresh water, circular tanks supplied with pumped/filtered/uv-sterilized seawater, and seawater net-pens for rearing sockeye salmon to maturity.

    Simple diffuse rear reflectors can enhance the light path length of weakly absorbed near infrared light in silicon solar cells and set a benchmark for more complex and expensive light trapping structures like dielectric gratings or plasmonic particles. We analyzed such simple diffuse rear reflectors systematically by optical and electrical measurements. We applied white paint, TiO2 nanoparticles, white backsheets and a silver mirror to bifacial silicon solar cells and measured the enhancement of the external quantum efficiency for three different solar cell geometries: planar front and rear side, textured front and planar rear side, and textured front and rear side. We showed that an air-gap between the solar cell and the reflector decreases the absorption enhancement significantly, thus white paint and TiO2 nanoparticles directly applied to the rear cell surface lead to the highest short circuit current density enhancements. The short circuit current density gains for a 200 um thick planar solar cell reached up to 1.8 mA/cm2, compared to a non-reflecting black rear side and up to 0.8 mA/cm2 compared to a high-quality silver mirror rear side. For solar cells with textured front side the short circuit current density gains are in the range between 0.5 and 1.0 mA/cm2 compared to a non-reflecting black rear side and do not significantly depend on the angular characteristic of the rear side reflector but mainly on its absolute reflectance.

    Hand-rearing of captive great ape infants is sometimes necessary but can have negative behavioral consequences. Modern hand-rearing protocols, including early integration into a diverse group of conspecifics, appear to reduce the negative consequences of hand-rearing, but the process of integration is not well studied. We investigated six potential metrics of success during the introduction of two hand-reared chimpanzee infants into a troop of nine other chimpanzees at the Maryland Zoo in Baltimore. Little aggression was observed and the infants continue to be maintained in the troop at publication. As we predicted, during the introduction the hand-reared infants showed consistent levels of stress-related behaviors, participated in affiliative interactions with all available partners, and acted, received, and mutually engaged in these interactions. Solitary behaviors by these infants were similar to a mother-reared infant in the same group. Each infant also formed a relationship with a specific female that involved nest-sharing, carrying, retrieval, and intervening to reduce risk to the infant; these relationships could be classified as allomothering because they involved maternal behavior but occupied significantly less of the infants' time than a maternal relationship. Contrary to our prediction, the hand-reared infants therefore spent significantly less time in social behavior than a mother-reared infant of the same age. In addition, the hand-reared infants continued to show strong social preferences for each other as introductions progressed and to direct a low but consistent number of nonfeeding social behaviors to humans. The successful introduction of hand-reared infants appeared to involve adding conspecific social relationships to the infants' social repertoire, but not eliminating social interactions directed at humans.

    Child maltreatment is a global problem but is more difficult to assess and manage in developing countries such as India where one-fifth of the world's total child population resides. Certain forms of maltreatment such as feticide, infanticide, abandonment, child labour, street-begging, corporal punishment and battered babies are particularly prevalent in India. Most physicians still need to be sensitized in order to suspect child abuse on the basis of unexplained trauma, multiple fractures, parental conflict and other corroborative evidence. This article summarizes the various aspects of this major problem in resource-poor settings in the hope that it will assist in the planning of services addressing child physical and sexual abuse and neglect in India and in other developing countries. A culture of non-violence towards children needs to be built into communities in order to provide an environment conducive to the overall development of the child. Rehabilitation of abused children and their families requires a multi-disciplinary service including paediatricians, child psychologists and social workers, and the training of police forces in how to tackle the problem.

    The objectives of the present study were 1) to validate the Antisocial Process Screening Device (APSD) in a sample of Russian juvenile delinquents; 2) to examine subgroups of delinquents with higher versus lower levels of childhood problem behaviors with respect to the APSD subscales, personality traits, and parental rearing; and 3) to attempt to replicate the previous finding that the APSD subscale measuring callous/unemotional traits can differentiate subgroups of delinquents with different precursors for problem behaviors (predominantly biological versus predominantly social). A group of 250 Russian juvenile inmates (mean age=16.4) was examined by means of the APSD completed by the staff at the correctional institution. The inmates completed several self-reports assessing their current and childhood behavior problems, personality traits and experienced parental rearing practices. A factor structure of the APSD was obtained that is similar, albeit not identical, to that from the original studies by Frick and colleagues [Frick, P.J., O'Brien, B.S., Wootton, J.M., McBurnett, K., (1994).

    This study describes results on sexual maturation and characteristics of natural spawned eggs to develop a method for the production of stable, healthy fertilized eggs from captive-reared yellowtail kingfish, Seriola lalandi. A total of 59 yellowtail kingfish were captured off the coast of Jeju Island, after which the broodstock was cultured in indoor culture tank (100 m(3)) until they were 6.1-14.9 kg in body weight. As part of the rearing management for induced sex maturation, the intensity of illumination was maintained at 130 lux. The photoperiod (light/dark; L/D) was set to a 12 L/12 D from October 2013 to January 2014, and 15 L/9 D from February 2014 to June 2014. Feeds comprised mainly EP (Extruded Pellets), with squid cuttlefish added for improvement of egg quality, and was given from April to June 2014. The first spawning of yellowtail kingfish occurred in May 3, 2014, at a water temperature of 17.0°C. Spawning continued until June 12, 2014, with the water temperature set at 20.5°C. Time of spawning was 26 times at this period. The total number of eggs that spawned during the spawning period was 4,449×10(3). The buoyant rate of spawning eggs and fertilization rate of buoyant eggs during the spawned period were 76.1% and 100%, respectively. The diameters of the egg and oil globule were 1.388 ± 0.041 mm and 0.378 ± 0.029 mm, respectively, which was higher in early eggs than in those from late during the spawned period. PMID:27660829

    Full Text Available Identifying alternative dietary protein sources and new types of outdoor rearing techniques that enhance animal welfare, thus optimising costs and production performance, are among the main objectives of nutritionists and breeders. The aim of this study was to compare two types of rations where pea and potato concentrate completely substituted soybean in intensively and extensively bred swine. Forty Large White × Duroc piglets weighing about 40 kg were divided into 4 groups of 10 sex- and weightmatched individuals: Indoor rearing + Control diet, Indoor rearing + Experimental diet, Outdoor rearing + Control diet, Outdoor rearing + Experimental diet. Different diets were formulated for the growing phase (40-100 kg and the fattening period (100-slaughter; pigs, weighed individually every 40 days to estimate the average daily gain and feed conversion rate, were slaughtered when they reached the weight for Italian ham production. The following measurements were obtained: carcass weight, slaughtered yield, weight of lean cuts, pH 45 minutes and 24 hours post mortem. 40 semimembranosus muscle samples were analysed for colour parameters (L*, a* and b*, moisture, fat, protein and ash while the energy values were calculated. Semimembranosus intramuscular fat and ham backfat were analysed for fatty acid profile. Statistical analysis of performances data was conducted using design with repeated measures and the slaughterhouse, meat and fat composition data were subjected to ANOVA. The results show that soybean can be completely substituted with other protein crops. Rearing and slaughterhouse performances were not affected by the diet, whereas significant differences emerged with the rearing system. Diet composition significantly affected lean meat proportion (50.0 vs 48.2 and fat thickness of 3/4 Thoracic Vertebra (25.3 vs 28.3 mm, while the rearing system significantly affected all carcass quality measures.

    Objective] This study presents a method for mass rearing of Aphidius gi-fuensis, a dominant endoparasitoid of Myzus persicae on tobacco in Southwest Chi-na. [Method] The tobacco cultivar Honghuadajinyuan (Nicotiana tabacum) was used as the host plant and M. persicae was the host insect. In a greenhouse, tobacco seedlings were reared in plastic trays. The seedlings at three-true-leaf stage were inoculated with two to three aphids per plant using aphid source with a parasitism rate of 47%±3.9%. [Result] By this inoculation method, the aphids and parasites were simultaneously inoculated on host plants. After approximately 25 d of rearing, we were able to produce 82.5±5.17 aphid mummies per tobacco seedling. A total of 445 500 aphid mummies were produced in one greenhouse (36 rearing trays per greenhouse) during an approximately 50-day rearing period. The emergence rate was 93.4%±2.76%, and 54% of the mummies were females. [Conclusion] The demonstrated technological feasibility of using tobacco seedlings for the mass rear-ing of A. gifuensis increases the potential for the biological control of M. persicae.

    The bean pod borer, Maruca vitrata Fabricius (Lepidoptera: Crambidae), is a serious pantropical pest of grain legumes. A suitable artificial diet is desirable for producing uniform insects for commercial purposes or research. Three previously described artificial diets, 1 newly-developed artificial diet, and cowpea (Vigna unguiculata (L.) Walp. (Fabales: Fabaceae)), the natural hostplant of M. vitrata, were used for rearing M. vitrata, and the life parameters were examined. The results indicated that insects completed a full life cycle only when the larvae were fed cowpea or the diet reported by Onyango and Ochieng'-Odero ( 1993 ), called the "D-OO diet." However, the rearing efficiency (i.e., larval and pupal survival, longevity of adults, and fecundity) on the D-OO diet was inferior to the rearing efficiency on cowpea. Subsequently, a new artificial diet was formulated based on soybean powder, Glycine max (L.) Merr. (Fabales: Fabaceae), and wheat germ, Triticum aestivum L. (Poales: Poaceae). The egg production, egg hatching, larval developmental duration, and pupal survival of the M. vitrata reared on the new artificial diet were found to be significantly improved relative to the D-OO diet, but were not significantly better than on the host-plant cowpea. The optimum rearing density was 15-25 larvae per box. There were no significant changes in reproductive potential after 8 successive generations of rearing on the new diet. These results indicated that the newly developed diet could serve as a viable alternative to cowpea plant for continuous rearing of M. vitrata.

  13. Environmental effects on behavioural development consequences for fitness of captive-reared fishes in the wild.

    Science.gov (United States)

    Johnsson, J I; Brockmark, S; Näslund, J

    2014-12-01

    Why do captive-reared fishes generally have lower fitness in natural environments than wild conspecifics, even when the hatchery fishes are derived from wild parents from the local population? A thorough understanding of this question is the key to design artificial rearing environments that optimize post-release performance, as well as to recognize the limitations of what can be achieved by modifying hatchery rearing methods. Fishes are generally very plastic in their development and through gene-environment interactions, epigenetic and maternal effects their phenotypes will develop differently depending on their rearing environment. This suggests that there is scope for modifying conventional rearing environments to better prepare fishes for release into the wild. The complexity of the natural environment is impossible to mimic in full-scale rearing facilities. So, in reality, the challenge is to identify key modifications of the artificial rearing environment that are practically and economically feasible and that efficiently promote development towards a more wild-like phenotype. Do such key modifications really exist? Here, attempts to use physical enrichment and density reduction to improve the performance of hatchery fishes are discussed and evaluated. These manipulations show potential to increase the fitness of hatchery fishes released into natural environments, but the success is strongly dependent on adequately adapting methods to species and life stage-specific conditions.

    The vector species Aedes albopictus (Skuse, 1894) was recorded in Turkey for the first time, near the Greek border, in 2011 and a high risk of expansion towards Aegean and Mediterranean coasts of Turkey was estimated. A preliminary study was planned to evaluate the possibility of creating a satellite mass rearing facility for this species and manage a larval rearing procedure by using the new mass-rearing technology proposed by the International Atomic Energy Agency (IAEA). For this purpose, the effects of different larval densities (1, 2, 3 and 4 larvae per ml) on the preimaginal development were evaluated by observing pupal, adult and male productivity using life cycle trials. Geometric morphometric analyses were also performed to define all phenotypic differences that occurred on the wing size and shape morphology of adult stage at the four different rearing conditions tested. A high pupation productivity was obtained with a larval density of 2 larvae/ml while adult emergence ratio was not affected by the densities tested. No significant difference was observed in shape of the wings among different densities in males and females. Nevertheless, a significant difference in female's centroid sizes was observed between the treatment groups 1-2 and 3-4 larvae/ml and in males centroid size reared at 1 larvae/ml versus the other densities.

Music, as a therapy was shown to have positive effects in child care, such as in premature infants, children in emergency care, children receiving surgery, children in oncology departments and handicapped children. The aim of this review was to study the therapeutic effects of music in child care at hospital. The method οf this study included bibliography research from both the review and the research internatio nal literature, which was referred to the therapeutic effects of music in Children's Hospital. Results: Most studies focus on the beneficial effects of music to child. The results of the study showed that music is widely used to enhance well‐being and appears to exert direct effects to child, which are mainly related to physiology and psychology, including changes in the vital signs, reductions in anxiety and pain, distraction of attention from unpleasant sensations and better communication with the environment at hospital. Furthermore, music exerts indirect effects to child since is able to cause positive modifications in nurses' behaviour and conduces to better performance in their duties. Conclusions: Music consists a low-cost "therapeutic instrument" for nurses to apply to child-patient and is found to be effective in producing positive outcomes. The nurses' knowledge of music therapy need to be improved and the therapeutic impact of music must be a result from systematic professional application.

    This paper presents preliminary outcomes associated with an experimental, longitudinal study of a Multiple Family Group (MFG) service delivery approach set within thirteen urban outpatient clinics serving children and their families living in inner-city, primarily African American and Latino communities. Specifically, this paper focuses on parent reports of child oppositional behavior and parenting stress over time. MFG is a flexible, protocol-driven approach designed to address the most common reason for referral to outpatient child mental health clinics, childhood behavioral difficulties. The MFG also aims to enhance family-level engagement and retention in ongoing care. Further, the service delivery model was collaboratively developed with intensive input from parents rearing children with conduct difficulties, parent advocates, community-based child mental health providers and services research staff in order to ultimately expand the number of effective service models that can be situated within "real world," urban child mental health settings.

    Rearing treatments used in captivity to prepare animals for reintroduction to the wild may have a profound effect on behavior and, possibly, affect their survival after reintroduction. This study examined the behaviors of captive-reared whooping cranes (Grus americana) upon their release in Florida to determine if rearing treatments may affect the behavior of the birds and how these affect their chances of survival in the wild. Individually tagged birds were observed at the rearing facility, the U.S. Geological Survey Patuxent Wildlife Research Center in Maryland, from hatch to 20 weeks of age and at the release site in Central Florida for up to 6 weeks post release. The rearing treatments were parent reared (PR), hand reared (HR), and hand reared with exercise (HRE). Observations at the rearing facility are described in a previous paper. At the release site, each bird was observed for 5 min every morning (0700?1000 h) and late afternoon (1500?1800 h) during the 6-week study period. Our results indicated that most of the time, the n = 34 birds were foraging (46.03 ? 1.48%), followed by nonvigilant (20.89 ? 0.73%), vigilant (19.21 ? 0.72%), or performing comfort behaviors (11.61 ? 1.28%). Data were analyzed using mixed models repeated measures ANOVA. There were no significant behavioral differences between HR and HRE birds. PR birds were found in larger groups than HR birds during the first 2 weeks post release and greater than HR and HRE birds afterwards. This may be interpreted as an antipredator strategy for birds that relied on parental guidance during rearing. HR and HRE birds foraged more than PR birds during the first 2 weeks post release and PR birds were more vigilant during the first 2 weeks post release. Across rearing treatments, the percentages of time spent foraging and engaged in vigilant behaviors during rearing were positively correlated with their behavior upon release. If any of these behaviors can be demonstrated to have relevance for the

    Male chickens belonging to three Italian purebreds – Ermellinata di Rovigo (ER), Robusta lionata (RL) and Robusta maculata (RM) – were studied. All the birds were reared under the same rearing conditions (from May until autumn). Chickens were reared under infra-red lamps from birth until 4 weeks of age with a 24L:0D photoperiod. Then they were kept outdoor: the photoperiod changed according to the season (from 16L:8D to 12L:12D). At 138 and 168 days of age 20 birds/breed were weighed and then...

    The broiler industry has become an important economic activity in Argentina. Global production of broiler meat has been growing in Argentina faster than for any other meats, possibly due to declining poultry prices and increasing incomes. Modern rearing systems can produce broilers ready to slaughter in 50 days, with the required 2.7kg of weight and a feed conversion of about 1.6kg feed/kg of meat. Nevertheless, broilers raised under these intensive conditions are exposed to various stressors every day. For many years, feed supplementation with antibiotics was widely used to stabilize the gut flora, improve general parameters and prevent avian diseases. However, the utility of antibiotics has been questioned because of the emergence and spread of antibiotic-resistant bacteria in meat. Therefore, there is a renewed interest in finding viable alternatives to antibiotics. One potential method is the supplementation of broiler diets with probiotics. This review provides an updated summary of the use of probiotics to improve sanitary conditions and enhance performance in broilers, demonstrating the role of probiotics as a reliable option to replace antimicrobial growth promoters.

    The effects of Mycoplasma gallisepticum (MG) infections on egg production, fertility, and hatchability were studied in captive-reared wild turkeys (Meleagris gallopavo). Three groups of adult birds, each consisting of four hens and two toms, were exposed to MG by the respiratory route at the beginning of their breeding season. Fourteen control birds received sterile growth medium. Although no mortality of infected or control birds occurred, egg production during the first breeding season after infection was reduced. The mean number of eggs/hen/day produced by infected groups the first breeding season postexposure (PE) was significantly lower than the control value. The mean number of eggs produced daily by the same hens 1 yr later was unaffected by MG infection. The percentage of fertile eggs produced by infected groups was slightly reduced in both the first and second breeding seasons PE. Hatchability of fertile eggs from infected hens was significantly lower than eggs from control hens. Productivity may be impaired if MG infections occur in free-ranging wild turkey populations.

    Results from a controlled study on a sample of 91 imprisoned drug dependents on perceived parental rearing practices using the EMBU and on parental family characteristics are presented. While few differences were observed between drug dependents and imprisoned controls-father less warm and mother more permissive in drug dependent group--comparisons of drug dependents with a general population sample revealed more differences between the two populations: drug dependents perceive both parents compared to the general population group as less rejective, very permissive, their mother as warmer and more overprotective and their father more inconsistent and less favouring them than siblings. Supportive evidence on the dependents' family psychopathology is provided by studying family characteristics. While our findings seem to support the prevailing view in the literature on the role of the mother of the drug dependent characterised by strong emotional bonds and overprotection as well as of the rather emotionally distant father, the question is raised on the contribution of other factors, such as psychopathic personality, on the above findings.

    Full Text Available Vehicle detection in traffic scenes is an important issue in driver assistance systems and self-guidedvehicles that includes two stages of Hypothesis Generation (HG and Hypothesis Verification (HV. Theboth stages are important and challenging. In the first stage, potential vehicles are hypothesized and in thesecond stage, all hypotheses are verified and classified into vehicle and non-vehicle classes. In this paper,we present a method for detecting front and rear on-road vehicles without lane information and priorknowledge about the position of the road. In the HG stage, a three-step method including shadow, textureand symmetry clues is applied. In the HV stage, we extract Pyramid Histograms of Oriented Gradients(PHOG features from a traffic image as basic features to detect vehicles. Principle Component Analysis(PCA is applied to these PHOG feature vectors as a dimension reduction tool to obtain the PHOG-PCAvectors. Then, we use Genetic Algorithm (GA and linear Support Vector Machine (SVM to improve theperformance and generalization of the PHOG-PCA features. Experimental results of the proposed HVstage showed good classification accuracy of more than 97% correct classification on realistic on-roadvehicle dataset images and also it has better classification accuracy in comparison with other approaches.

    Full Text Available Abstract:The objective of this work was to define the traits that should be included as breeding objectives for Nellore cattle, according to simulations with a bio-economic model for rearing systems. The economic values (EVs of the traits were calculated as the differences between the profits due to an increased performance of 1% in each trait, with the others traits remaining constant. To determine the impact of each selection on the revenue system, two scenarios were simulated based on the traits being selected. In the first scenario, the adopted selection criteria were: weaning weight (WW, weaning rate (WR, yearling weight (YW, and mature cow weight (MCW. In the second scenario, the cumulative productivity (CP of dams was used as an indirect evaluation of the performance of calves, with all the other traits included, except WW. In the first scenario, an EV of R$ 1.44 kg-1 was obtained for WW. In the second scenario, an EV of R$ 2.91 kg-1 was obtained for CP. The trait with the highest EV in both scenarios was WR, which enhanced the profits by R$ 3.21 for each 1% increased performance. The meat price paid to the producer is the factor with the greatest impact on the EVs of all examined traits.

    Physico-chemical characteristics and quality traits of the raw ingredients (muscle cuadriceps femoris, liver and adipose tissue) and the pâtés made from extensively reared Iberian pigs and intensively reared white pigs, were evaluated. The differences found between muscles, livers and adipose tissues from Iberian and white pigs influenced the characteristics of the pâtés. Compared to pâtés from white pigs, pâtés from Iberian pigs had a higher content of heme iron (27.5 μg/g vs 11.5 μg/g; p<0.05) and lower content of non-heme iron (27.5 μg/g vs 33.7 μg/g; p<0.05). Pâtés from Iberian pigs exhibited a darker colour (L (∗):18.6 vs 15.9, p<0.05) with less redness (a (∗) values: 9.1 vs 11.3; p<0.05) and yellowness (b (∗) values: 13.1 vs 14.8, p<0.05). Thus, pâtés from white pigs had higher values of chroma (18.6 vs 15.9, p<0.05) and smaller values of hue (52.5 vs 55.2, p<0.05) that those from Iberian pigs' pâtés. In fatty acid composition, pâtés from white pigs had higher proportions of SFA (37.9% vs 32.8%, p<0.05) and PUFA (14.4% vs 9.6%, p<0.05) than pâtés from Iberian pigs and lower percentages of oleic (53.4% vs 43.6%, p<0.05) and total of MUFA (57.5% vs 47.6%, p<0.05). Pâtés from Iberian pigs had a lower n-6/n-3 values (13.2 vs 17.2; p<0.05).

    2011-01-01

    Full Text Available We describe a rearing protocol that allowed us to raise the threatened butterfly, Argynnis diana (Nymphalidae, while bypassing the first instar overwintering diapause. We compared the survival of offspring reared under this protocol from field-collected A. diana females from North Carolina, Georgia, and Tennessee. Larvae were reared in the lab on three phylogenetically distinct species of Southern Appalachian violets (Viola sororia, V. pubescens, and V. pedata. We assessed larval survival in A. diana to the last instar, pupation, and adulthood. Males reared in captivity emerged significantly earlier than females. An ANOVA revealed no evidence of host plant preference by A. diana toward three native violet species. We suggest that restoration of A. diana habitat which promotes a wide array of larval and adult host plants, is urgently needed to conserve this imperiled species into the future.

    2000-08-01

    There is an extensive literature on the relationship between birth order and psychological traits, but no previous study has investigated the influence of ordinal position on personality development within adoptive siblings. Such a design is important because it effectively separates the effects of biological birth order and rearing order. Here we report data from two adoption cohorts in which subjects were biological first-borns reared in various ordinal positions. Data were analyzed with reference to Sulloway's (1996) evolutionarily based sibling rivalry theory of birth order effects. Between- and within-family analyses indicated that rearing order's influence on personality was very weak. The only clear difference was for conscientiousness, on which first-reared siblings scored higher. We draw possible implications for Sulloway's theory and speculate upon an alternative, prenatal biological process that may produce birth order differences.

    Child life programs are an important component of pediatric hospital-based care to address the psychosocial concerns that accompany hospitalization and other health care experiences. Child life specialists focus on the optimal development and well-being of infants, children, adolescents, and young adults while promoting coping skills and minimizing the adverse effects of hospitalization, health care, and/or other potentially stressful experiences. Using therapeutic play, expressive modalities, and psychological preparation as primary tools, in collaboration with the entire health care team and family, child life interventions facilitate coping and adjustment at times and under circumstances that might otherwise prove overwhelming for the child. Play and developmentally appropriate communication are used to: (1) promote optimal development; (2) educate children and families about health conditions; (3) prepare children and families for medical events or procedures; (4) plan and rehearse useful coping and pain management strategies; (5) help children work through feelings about past or impending experiences; and (6) establish therapeutic relationships with patients, siblings, and parents to support family involvement in each child's care.

  3. Rearing tsetse flies for use in sterile insect technique vector control programmes

    International Nuclear Information System (INIS)

    In past years, considerable progress has been achieved in the mass rearing of tsetse flies for use in vector control programmes. This was made possible through the introduction of the membrane feeding system and the development of strict quality control procedures for different developmental stages of tsetse and for various aspects that are relevant to insect production, such as bloods diet quality screening. The maintenance of large tsetse fly colonies, e.g. more than 100,000 producing females that may provide more than 12,000 reproductively sterile males and equal numbers of surplus female material, is feasible without major efforts. Calculations of labour requirements and the costs involved for different mass rearing systems can now be conducted. Depending on the purpose for which the insects are reared, different types of mass rearing facilities may be erected (a small stationary insect factory, large breeding centre or mobile production plant). Sexually sterile tsetse from a mass rearing system may be used for different reasons in tsetse control or eradication campaigns, namely for eradication or control through the sterile insect technique, for ecological monitoring of a target tsetse population, particularly if it is under advanced control, and for transtaxon control of closely related species (or subspecies). Bottlenecks for a larger scale field use of mass reared tsetse remain for the time being: (a) the relatively long process of strain adaptation to mass rearing conditions, (b) laborious sexing procedures of mature insects upon emergence and after mating and (c) unavailability of simple genetic tools to collect baseline information on the suitability of a mass reared strain to combat an identified target population and to assess the degree of isolation of a target population.

    1992-01-01

    Captive-reared Mississippi sandhill cranes (Grus canadensis pulla) reared at the Patuxent Wildlife Research Center (Patuxent) have been released at the Mississippi Sandhill Crane National Wildlife Refuge (MSCNWR) since 1981. Of 131 birds released through December 1990, 103 were reared by foster parents. The remaining 28 were experimentally hand-reared in 1989 and 1990. After refining release procedures, parent-reared birds have integrated into the wild flock, many have survived, and some have bred. Releases of hand-reared cranes elsewhere in the 1970's were largely unsuccessful, at least in part due to the lack of a lengthy acclimation period. A new hand-rearing protocol holds promise in producing release-worthy birds. The technique employs some features first used in the 1960's (e.g., a costume for the human caretaker and model crane heads used to train chicks to feed). In the mid-1980's, the following features were added: (1) the costumed caretaker was given a visor and feathers, (2) a taxidermic crane head or a hand puppet was held or suspended from the ceiling for use in stimulating chicks to feed, (3) a taxidermic mount of a brooding crane supplied warmth, (4) a full-sized live crane was maintained in an adjacent pen and in visual contact with neonatal young to provide an imprinting model, and (5) a small group of adult (or subadult) cranes was penned adjacent to the outdoor chick pens to provide socialization models. Recent releases of Mississippi sandhill cranes hand-reared according to this protocol and released in Mississippi have had high first-year survival rates. The now-operational technique holds promise for producing large numbers of release-worthy birds.

    2012-05-01

    The requirement for efficient mosquito mass rearing technology has been one of the major obstacles preventing the large scale application of the Sterile Insect Technique against mosquitoes. At the Food and Agriculture Organization/International Atomic Energy Agency (FAO/ IAEA) Insect Pest Control Laboratories we developed a larval rearing unit based on the use of a stainless steel rack that operates 50 thermoformed ABS plastic trays and is expected to be able to successfully rear 140,000-175,000 Anopheles arabiensis (Patton) adult mosquitoes per rack. The mechanized rearing unit is simple to handle, maintains minimal water temperature variation and negligible water evaporation and allows normal larval development. The mosquito mass-rearing tray was designed to provide a large surface area of shallow water that would closely mimic natural breeding sites. The trays stack into a dedicated rack structure and filling and draining were easily performed. The close stacking of the trays in the rack and the possibility to tightly line up several racks makes this rearing unit a valid solution for maximal use of the space thus reducing construction, heating, and cooling costs. The low amount of labor required to operate the system also reduces labor costs that represent one of the main expenditures in any mass rearing facility operation. Preliminary experiments performed on Aedes albopictus (Skuse) also confirm the possibility of successfully extending the use of this technology to other mosquito species. Our larval rearing unit could enhance any mosquito control strategy in which large-scale releases of mosquitoes are needed to suppress or replace natural populations. PMID:22679867

    An electronic spreadsheet is described which helps users to design, equip and operate facilities for the mass rearing of insects for use in insect pest control programmes integrating the sterile insect technique. The spreadsheet was designed based on experience accumulated in the mass rearing of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), using genetic sexing strains based on a temperature sensitive lethal (tsl) mutation. The spreadsheet takes into account the biological, production, and quality control parameters of the species to be mass reared, as well as the diets and equipment required. All this information is incorporated into the spreadsheet for user-friendly calculation of the main components involved in facility design and operation. Outputs of the spreadsheet include size of the different rearing areas, rearing equipment, volumes of diet ingredients, other consumables, as well as personnel requirements. By adding cost factors to these components, the spreadsheet can estimate the costs of facility construction, equipment, and operation. All the output parameters can be easily generated by simply entering the target number of sterile insects required per week. For other insect species, the biological and production characteristics need to be defined and inputted accordingly to obtain outputs relevant to these species. This spreadsheet, available under http://www-naweb.iaea.org/nafa/ipc/index.html, is a powerful tool for project and facility managers as it can be used to estimate facility cost, production cost, and production projections under different rearing efficiency scenarios.

    The biological parameters ofMacrolophuspygmaeus Rambur after prolonged rearing in the absence of plant materials were compared with those of conventionally plant-reared predators.When eggs of Ephestia kuehniella Zeller were provided as food,developmental and reproductive fitness of M.pygmaeus reared for over 30 consecutive generations using artificial living and oviposition substrates was similar to that of predators kept on tobacco leaves.Plantless-reared fifth instars of the predator also had similar predation rates on second instars of the tobacco aphid,Myzus persicae nicotianae Blackman,as their peers maintained on plant materials.In a further experiment,predation on aphid prey by fifth instar M.pygmaeus fed one of two egg yolk-based artificial diets was compared with that of nymphs fed E.kuehniella eggs.Despite their lower body weights,predators produced on either artificial diet killed similar numbers of prey as their counterparts reared on lepidopteran eggs.Our study indicates that artificial rearing systems may be useful to further rationalize the production of this economically important biological control agent.

    Reproduction is a demanding activity, since organisms must produce and, in some cases, protect and provision their progeny. Hence, a central tenet of life-history theory predicts that parents have to trade parental care against body maintenance. One physiological cost thought to be particularly important as a modulator of such trade-offs is oxidative stress. However, evidence in favour of the hypothesis of an oxidative cost of reproduction is contradictory. In this study, we manipulated the brood size of wild barn swallows Hirundo rustica soon after hatching of their nestlings to test whether an increase in nestling rearing effort translates into an increased oxidative damage and a decreased antioxidant protection at the end of the nestling rearing period. We found that, while plasma oxidative damage was unaffected by brood size enlargement, females rearing enlarged broods showed a decrease in plasma non-enzymatic antioxidants during the nestling rearing period. This was not the case among females rearing reduced broods and among males assigned to either treatment. Moreover, individuals with higher plasma oxidative damage soon after the brood size manipulation had lower plasma non-enzymatic antioxidants at the end of the nestling rearing period, suggesting that non-enzymatic antioxidants were depleted to buffer the negative effects of high oxidative damage. Our findings point to antioxidant depletion as a potential mechanism mediating the cost of reproduction among female birds.

    The present study compared vertebral deformities of hatchery-reared and wild-caught juvenile Japanese flounder, Paralichthys olivaceus. A total of 362 hatchery-reared flounder (total length 122.5-155.8 mm) were collected from three commercial hatcheries located in Yantai, East China, and 89 wild fish (total length 124.7-161.3 mm) were caught off Yangma Island near Yantai City (37°27'N, 121°36'E). All the fish were dissected, photographed, and images of the axial skeleton were examined for vertebral deformities. Compared with wild-caught flounder in which no deformed vertebrae were detected, 48 (13.3%) hatcheryreared fish had deformed vertebrae. The deformities were classified as compression, compression-ankylosis, and dislocation-ankylosis. The vertebral deformities were mainly localized between post-cranial vertebra 1 and 3, with vertebrae number 1 as the most commonly deformed. The causative factors leading to vertebral deformities in reared Japanese flounder may be related to unfavorable temperature conditions, inflammation, damage, or rupture to the intervertebral ligaments under rearing conditions. Furthermore, no significant difference in the total number of vertebral bodies was observed between wild-caught (38.8±0.4) and hatchery-reared flounder (38.1±0.9) ( P>0.05). However, the number of vertebral bodies of hatchery-reared and wild-caught flounder ranged from 35 to 39 and from 38 to 39, respectively.

    Full Text Available Our research focuses on developing techniques to rear ladybird beetles (Coleoptera: Coccinellidae. We evaluated the effects of rearing density on survival, growth, and development of Coleomegilla maculata. The hypothesis that a low to moderate rearing density has limited or no effects on survival and development was tested. C. maculata first instars were reared to pupae at a density of 1, 5, 10, 15, or 20 individuals per arena (2.5 cm high, 9.0 cm diameter, and 159 cm3 volume and fed powdered brine shrimp (Artemia franciscana eggs. More larvae survived at the 1 and 5 densities, but no differences were detected between the 10, 15, or 20 densities. Median survival rate was at least 90% for larvae and 100% for pupae at the 10, 15, and 20 densities. Development time, body weight, and sex ratio were unaffected by rearing density. Overall, this study suggests that C. maculata larvae can be reared successfully at a density of 20 larvae/159 cm3 (≈ 0.126 larvae/cm3 in containers provisioned with powdered A. franciscana eggs. Scaling-up the size of containers, and C. maculata density in these containers, should be possible.

    Full Text Available The aim of this review is to summarise the main causes of poor welfare in intensively reared dairy cows. Intensive farming systems are considered, both from a structural and a managerial point of view, for their constraints that may limit animal welfare: possible physical activity; acceptable interactions with humans and other animals; feeding and watering, protection from climate, parasites, and diseases. The dairy farms managed according to the organic rules do not always guarantee, per se, better welfare conditions; organic or low input dairy farming needs to consider the right interaction among cattle breed and herd management, focusing on the actual quality of feedstuffs meet face cow requirements. The considered structural aspects evidence how special care must be given to the rest area (straw yard or cubicle; to the floors that should be not too hard or abrasive and not slippery; to the cubicle bedding material to ensure hygiene, softness, and dryness; to the feeding (and watering area to reduce conflicts; to a microclimate control system, to avoid heat stress during summer time. The importance of proper management for animal welfare is evidenced for buildings and equipment, to have clean and comfortable stables and well functioning milking machines; nutritive and storage quality of feeds; diet suitability (energy, protein, physically efficient fibre, buffers etc., in the different phases of a dairy cow’s life (dry period, close-up, transition, and lactation; feed distribution (frequency and time, and 24h availability. Special attention has to be paid to the social aspects, regarding both animal competition (stocking density, group size, and human/animal interactions (methods of management and manipulation. The interaction between welfare and health requires special attention. Poor welfare can cause immune depression, thus increasing the risk of disease. In turn, any disease that causes an inflammatory response may determine depression

    The association between family structure instability and children’s life chances is well documented, with children reared in stable, two-parent families experiencing more favorable outcomes than children reared in other family arrangements. This study extends prior research by distinguishing between father-entrances into and father-exits from the household, by distinguishing between the entrance of a biological father and a social-father, and by testing for interactions between family structure instability and children’s age, gender and genetic characteristics. Using data from the Fragile Families and Child Wellbeing Study (n=2493) and focusing on changes in family structure between birth and age 9, we find that father-exits are associated with increases in children’s anti-social behavior, which is a strong predictor of health and wellbeing in adulthood. The pattern for father-entrances is more complicated, with biological father entrances being associated with lower anti-social behavior among boys, and social-father entrances being associated with higher anti-social behavior among boys with certain genetic variants. Child’s age at the time of family change does not moderate the association with children’s behavior. However, incorporating genetic information into our models sharpens the findings substantially, showing how such data can enrich our understanding of the intergenerational mobility process.

    2006-01-01

    The side-effects of pesticides (insecticides, fungicides, herbicides and plant growth regulators) used on cotton were tested on adults and pupae of Trichogramma pretiosum Riley reared in the laboratory on two different hosts, the Angoumois grain moth (Sitotroga cerealella Olivier) and the Mediterranean flour moth (Ephestia kuehniella (Zeller)). The eggs of the host enclosing the parasitoid pupae received direct pesticide sprays, while the adults of the parasitoid were exposed to the pesticides through contact with residues on sprayed eggs offered to parasitism. Alpha-cypermethrin, carbosulfan, deltamethrin, endosulfan, profenofos and zeta-cypermethrin were highly noxious to the parasitoid, significantly reducing the percentage of emergence and parasitism of T. pretiosum developing in E. kuehniella or S. cerealella eggs. However, the pupal stage of the parasitoid developing in S. cerealella eggs was less susceptible to alpha-cypermethrin and deltamethrin. Lufenuron and metamidophos greatly reduced the percentage of adult emergence from eggs of both hosts, while novaluron only interfered on this variable when the wasps were developing in E. kuehniella eggs. However, lufenuron and monocrotophos had no effect on the parasitoid pupae of T. pretiosum developing in E. kuehniella eggs. Chlorfluazuron, diafenthiuron, diflubenzuron, fentin hydroxide, mepiquat chloride, novaluron, thiacloprid and triflumuron did not affect T. pretiosum emergence when eggs of S. cerealella enclosing pupae of the wasps were surface treated. The pesticides azoxystrobin, carbendazin + thiram, mepiquat chloride and novaluron had no effect on the ability of the wasps to parasitise E. kuehniella eggs. However, only mepiquat chloride did not affect the percentage of F1 wasps emerging from E. kuehniella eggs. The remaining pesticides moderately reduced the percentage of emergence and parasitism of the wasps when they had contact with the chemicals during their pupal or adult stage. Thus there were

    Full Text Available Information from 150 females was obtained during the year 1998-99 to investigate status of backyard chicken in Chitral. Estimated human population and number of backyard birds in Chitral were 0.295 and 0.747 million, respectively. Average household flock size was 23.14 ± 1.97 birds, representing 8.04 ± 1.23, 6.83 ± 1.13, 5.67 ± 0.85 and 2.60 ± 0.27 number of Saso, Desi (non-descript indigenous chicken, Rhode Island Red (RIR and Fayumi birds, respectively. Household flock size and per capita available birds were higher in double than in transitional crop zone. Training status of the farmers, vaccination schedule and crop production zone affected egg production and mortality in backyard chickens. Average mortality in a flock was 13.56 ± 1.38%, representing higher mortality (P<0.05 in Saso as compared to non-descript indigenous Desi chicken. Total annual number of eggs obtained by a household from backyard chicken was 2975.95 ± 71.22 eggs, representing 378.28 ± 17.45 and 128.61 ± 21.14 eggs per capita and per bird, respectively. Saso chicken (176.22 ± 21.23 eggs as compared to non-descript indigenous Desi chicken (58.83 ± 5.27 eggs produced higher number of eggs per bird. Average number of eggs used for hatching purpose and per capita eggs consumed was 56.34 ± 3.37 and 137.68 ± 23.61, respectively. Mixed rearing practice of exotic birds with Desi chicken resulted in non-broodiness problem that adversely affected hatching performance as reported by most of the farmers. Proper health coverage, provision of training in poultry production, higher flock size, introduction of exotic birds, avoiding haphazard breeding and reduction in mortality were suggested as key factors for better backyard chicken productivity in Chitral.

    The bean pod borer, Maruca vitrata Fabricius (Lepidoptera: Crambidae), is a serious pantropical pest of grain legumes. A suitable artificial diet is desirable for producing uniform insects for commercial purposes or research. Three previously described artificial diets, 1 newly-developed artificial diet, and cowpea (Vigna unguiculata (L.) Walp. (Fabales: Fabaceae)), the natural hostplant of M. vitrata, were used for rearing M. vitrata, and the life parameters were examined. The results indicated that insects completed a full life cycle only when the larvae were fed cowpea or the diet reported by Onyango and Ochieng'-Odero ( 1993 ), called the "D-OO diet." However, the rearing efficiency (i.e., larval and pupal survival, longevity of adults, and fecundity) on the D-OO diet was inferior to the rearing efficiency on cowpea. Subsequently, a new artificial diet was formulated based on soybean powder, Glycine max (L.) Merr. (Fabales: Fabaceae), and wheat germ, Triticum aestivum L. (Poales: Poaceae). The egg production, egg hatching, larval developmental duration, and pupal survival of the M. vitrata reared on the new artificial diet were found to be significantly improved relative to the D-OO diet, but were not significantly better than on the host-plant cowpea. The optimum rearing density was 15-25 larvae per box. There were no significant changes in reproductive potential after 8 successive generations of rearing on the new diet. These results indicated that the newly developed diet could serve as a viable alternative to cowpea plant for continuous rearing of M. vitrata. PMID:24785903

    Feenders, Gesa; Bateson, Melissa

    2011-01-01

    Pending changes in European legislation ban the use of wild-caught animals in research. This change is partly justified on the assumption that captive-breeding (or hand-rearing) increases welfare of captive animals because these practices result in animals with reduced fear of humans. However, there are few actual data on the long-term behavioural effects of captive-breeding in non-domestic species, and these are urgently needed in order to understand the welfare and scientific consequences of adopting this practice. We compared the response of hand-reared and wild-caught starlings to the presence of a human in the laboratory. During human presence, all birds increased their general locomotor activity but the wild-caught birds moved away from the human and were less active than the hand-reared birds. After the human departed, the wild-caught birds were slower to decrease their activity back towards baseline levels, and showed a dramatic increase in time at the periphery of the cage compared with the hand-reared birds. We interpret these data as showing evidence of a greater fear response in wild-caught birds with initial withdrawal followed by a subsequent rebound of prolonged attempts to escape the cage. We found no effects of environmental enrichment. However, birds in cages on low shelves were less active than birds on upper shelves, and showed a greater increase in the time spent at the periphery of their cages after the human departed, perhaps indicating that the lower cages were more stressful. In demonstrating reduced fear of humans in hand-reared birds, our results support one of the proposed welfare benefits of this practice, but without further data on the possible welfare costs of hand-rearing, it is not yet possible to reach a general conclusion about its net welfare impact. However, our results confirm a clear scientific impact of both hand-rearing and cage position at the behavioural level. PMID:21364770

  12. Review of rearing-related factors affecting the welfare of laying hens.

    Laying hens may face a number of welfare problems including: acute and chronic pain caused by beak trimming; exaggerated fearfulness that may cause stress and suffocation; difficulties in locating resources, resulting potentially in emaciation and dehydration; frustration and boredom, caused by an environment that is barren; feather pecking; cannibalism; foot lesions; and bone fractures. In Europe, a greater proportion of laying hens are housed in non-cage systems compared to the rest of the world. The extent of the different welfare problems may therefore vary between countries as the type of housing system influences the risk of suffering. More generally, many of these welfare problems are influenced by the rearing environment of the pullets. This article therefore focuses on welfare problems in laying hens that can be traced back to rearing. Factors that have been studied in relation to their effects on bird welfare include beak trimming, housing type, furnishing, enrichment, feeding, stocking density, flock size, sound and light levels, concentration of gasses, age at transfer from rearing to production facilities, similarity between rearing and production facilities, competence of staff, and interactions between bird strain and environment. The present review aims to summarize rearing-related risk factors of poor welfare in adult laying hens housed according to European Union legislation. It aims to identify gaps in current knowledge, and suggests strategies for improving bird welfare by improving rearing conditions. Two main conclusions of this work are that attempts should be made to use appropriate genetic material and that beak trimming should be limited where possible. In addition to this, the rearing system should provide constant access to appropriate substrates, perches, and mashed feed, and should be as similar as possible to the housing system used for the adult birds. Finally, young birds (pullets) should be moved to the production facilities before

  13. Growth and social behavior in a cichlid fish are affected by social rearing environment and kinship

    Living in groups is a widespread phenomenon in many animal taxa. The reduction of predation risk is thought to be an important cause for the formation of groups. Consequently, grouping behavior is particularly pronounced during vulnerable life stages, i.e., as juveniles. However, group living does not only provide benefits but also imposes costs on group members, e.g., increased competition for food. Thus, benefits of grouping behavior might not be evident when predation risk is absent. The adaptive significance of living and also developing in a group independent from predation risk has received relatively little attention although this might have important implications on the evolution and maintenance of group living. The first aim of the present study was to examine whether the social environment affects juvenile performance in the cichlid fish Pelvicachromis taeniatus and, secondly, whether kinship affects social behavior. Kin selection theory predicts benefits from grouping with kin. Here, we demonstrate that juveniles reared in a group grow on average faster compared to juveniles reared in isolation under standardized laboratory conditions without predation risk. Furthermore, we found significant differences in social behavior between juveniles reared in a group and reared in isolation. Fish reared in isolation were significantly more aggressive and less willing to shoal than group-reared fish. As expected, genetic relatedness influenced social behavior in group-reared fish as well: dyads of juveniles consisting of kin showed increased group cohesiveness compared to non-kin dyads. We discuss the potential benefits of group living in general and living with kin in particular.

    As one phase of a comprehensive canopy load investigation, conventional front and rear sliding canopies which are typified by installation on the SB2C-4E airplane, were tested in the Langley full-scale tunnel to determine the pressure distributions and the aerodynamic loads on the canopies. A preliminary analysis of the results of these tests is presented in this report. Plots are presented that show the distribution of pressure at four longitudinal stations through each canopy for a range of conditions selected to determine the effects of varying canopy position, yaw, lift coefficient, and power. The results indicate that the maximum loads, based on the external-internal pressure differential, for the front and rear canopies were obtained with the airplane simulating the high speed flight condition. The highest loading on the front canopy was in the exploding direction for the configuration with the front and rear canopies closed. The highest loads on the rear canopy were in the crushing direction with the front canopy open and the rear canopy closed. For most of the simulated flight conditions, the highest loads on the front canopy, per unit area, were over twice as great as the highest loads on the rear canopy when the comparison was made for the most critical canopy configuration in each case. The external pressure distribution over the front and rear canopies, which were fairly symmetrical to 0 degree angle of yaw, were greatly distorted at other yaw attitudes, particularly for the propeller operating conditions. These distorted pressure distributions resulted in local exploding and crushing loads on both canopies which were often considerably higher than the average canopy loads.

    Parasitoids of the Encarsia genus (Hymenoptera: Aphelinidae) are important biological control agents against whiteflies. Some of the species in this genus not only parasitize their hosts, but also kill them through host feeding. The whitefly parasitoid, Encarsia formosa Gahan, was examined to determine whether the rearing host species affects its subsequent host-feeding capacity and parasitism. E. formosa wasps were reared on Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae) and Bemisia tabaci (Gennadius) 'Q', and their subsequent host-feeding capacity and parasitism of T. vaporariorum and B. tabaci were examined. E. formosa reared on T. vaporariorum were significantly larger in body size than those reared on B. tabaci, but these wasps killed a similar number of whitefly nymphs by host feeding when they attacked the same host species on which they were reared. Regardless of the species on which it was reared, E. formosa fed significantly more on the B. tabaci nymphs than on the T. vaporariorum nymphs. The number of whitefly nymphs parasitized by E. formosa differed between the wasps reared on T. vaporariorum and those reared on B. tabaci depending on which whitefly species was offered as a host. In addition, the wasps reared on T. vaporariorum parasitized significantly more on T. vaporariorum than those reared on B. tabaci. The wasps reared on B. tabaci, however, parasitized similar numbers of whiteflies of both host species. The results indicated that the host-feeding capacity of E. formosa was affected more by the host species attacked than by the rearing host species, but the parasitism was affected by the host species attacked and the rearing host species. Generally, E. formosa reared on T. vaporariorum killed more T. vaporariorum nymphs by parasitism and host feeding than those reared on B. tabaci. Additionally, a similar number of B. tabaci nymphs were killed by parasitism and host feeding regardless of the rearing host species. Currently

    Full Text Available The periwinkle Littorina littorea (L. is a common prosobranch gastropod at the North Atlantic coasts, ranging from Greenland to New Jersey in America and, from Portugal to the White Sea in Europe (Johannesson, 1988. It presents a planktonic development; females release planktonic egg capsules that are pelagic, asymmetrically biconvex with a flat peripheral rim. The egg capsules contain a maximum of nine eggs (Linke, 1933; more commonly, they contain one to three (Cummins et al, 2002. Upon release, the egg capsules swell osmotically and burst after five to six days. Each egg hatches into a free swimming veliger larva and remains in this planktonic stage for six to seven weeks (Fish, 1979. At hatching larvae measure about 180 micrometers long and are competent to settle after spending 2-6 weeks in the plankton and reaching about 300-360 micrometers in length (Hohenlohe, 2002. Metamorphosis may be delayed if conditions are not suitable and it results in considerable variation of settlement times, with larvae settling on the shore throughout several months of the year. Adults of L. littorea species are ecologically similar, so this genus is a potential model system for testing the hypothesis that gene flow among populations should be higher in species with planktonic larvae because of their greater dispersal capacity (Jablonski and Lutz, 1983. L. littorea is of economic interest in Portugal where it is highly appreciated as shellfish food, being the peak season of consumption in summer. Since the local production is not sufficient to meet demand, it has been necessary to import stocks from abroad (mainly from Scotland and Ireland in order to satisfy market needs. For this reason, the development of strategies to produce L. littorea in Portugal is crucial. This work aims to determine basic rearing conditions and obtain data on L. littorea larval development and growth rate. These results are important to establish the conditions for cultivating

    Full Text Available The paper presents an overview of research findings on influence of family environment, especially parental behaviour, on child's development. Contemporary authors question early socialization researchers' claims that family characteristics and parental behaviour have important influence on behaviour of their children. Later researchers examined the size and durability of possible effects of family environment on child development. In addition, they focused on establishing whether it is actually the parental behaviour that influences child's development or, on the contrary, parental behaviour represents mainly a reaction to child's characteristics. Behaviour genetic studies have provided evidence that many traditional measures of family environment, including measures of parental behaviour, show genetic influence, thus reflecting genetically influenced child characteristics. Behaviour geneticists also suggest that environmental influences on child (personality development include predominantly non-shared environment, i.e. individual child's specific experiences, his/her own perceptions and interpretations of objectively same events. Based on empirically determined significant genetic effects on most behavioural traits and inconclusive results of studies on effects of family environment on child development some authors believe that it is not the parents, but rather genetic factor and/or peers who have the key role in child development. With respect to findings of behaviour genetics numerous recent studies of relations between family environment and child development involve child specific measures of (extrafamilial environment and examine the interactions between characteristics of an individual and those of his/her environment.

    2015-09-01

    Full Text Available The present study compares the efficiency of ovarian maturation and spawning success between wild-caught and pond-reared Penaeus monodon females after unilateral eyestalk ablation. The earliest spawning time after eyestalk ablation was 5.9 days in wild-caught females, which is significantly shorter than the spawning time in pond-reared females (10.5 days. Both wild-caught and pond-reared females repeatedly spawned after eyestalk ablation. On average, each wild-caught female spawned 2.94 times while each pond-reared female spawned only 1.09 times. The spawning induction rate, egg hatching rate, and the number of eggs per spawning were significantly greater in wild-caught females than in pond-reared females. However, the egg size was not significantly different between wild-caught and pond-reared females. Four shrimp sizes (60, 80, 100 and 120 (± 1.0 g were tested in this study and body weight significantly affected ovarian induction in pond-reared females but not in wild-caught females. Within the same body-weight class, the egg number per spawn in wild-caught females was significantly greater than that in pond-reared females. The egg production per spawn of the pond-reared females in the 120-g size group was two times higher than that in the pond-reared females in the 80-g size group. In conclusion, the fecundity of wild-caught P. monodon females is significantly higher than that of pond-reared P. monodon females. In breeding pond-reared P. monodon, the recommended minimum body weight of females is over 80 g, and the desirable body weight is over 100 g.

  1. Study on the SiN_x/Al rear reflectance performance of crystalline silicon solar cells

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    The performance of internal rear surface reflectance of crystalline silicon solar cells is becoming more and more important with the decrease of thickness of the silicon wafers. In this paper PC1D was used to simulate the correlations between the rear surface reflectance and the electrical as well as optical properties of the solar cells. The results showed that the short circuit current, open circuit voltage and quantum efficiency were all enhanced with the increase of the rear reflectance. When the rear reflectance increased from 60% to 100%, the short circuit current, open circuit voltage and maximum output power were improved by about 0.128 A, 0.007 V, and 0.066 W, respectively. The internal quantum efficiency was improved by 39.9%, the external quantum increased by 17.4%, and the efficiency of the solar cells was enhanced by 0.4% at 1100 nm wavelength. The screen-printing was selected to prepare SiNx/Al reflector, and experimental results showed that the SiNx/Al reflector has desired characteristic of internal rear reflectance, with the reflectivity of 15% higher than that of conventional aluminum BSF at 1100 nm wavelength.

    A reliable literature finds that traits are related to each other in an organized hierarchy encompassing various conceptualizations of personality (e.g., Big Three, five-factor model). Recent work suggests the potential of a similar organization among our closest nonhuman relative, chimpanzees (Pan troglodytes), with significant links to neurobiology suggesting an evolutionarily and neurobiologically based hierarchical structure of personality. The current study investigated this hierarchical structure, the heritability of the various personality dimensions across levels of the hierarchy, and associations with early social rearing experience in a large sample (N = 238) of socially housed, captive chimpanzees residing in 2 independent colonies of apes. Results provide support for a hierarchical structure of personality in chimpanzees with significant associations with early rearing experiences. Further, heritabilities of the various dimensions varied by early rearing, with affective dimensions found to be significantly heritable among mother-reared apes, whereas personality dimensions were largely independent of relatedness among the nursery-reared apes. Taken together, these findings provide evidence for the influence of both genetic and environmental factors on personality profiles across levels of the hierarchy, supporting the importance of considering environmental variation in models of quantitative trait evolution.

    This report covers the 1996-1998 Natural Rearing Enhancement System (NATURES) research for increasing hatchery salmon postrelease survival and producing fish with more wild-like behavior, physiology, and morphology prior to release. Experiments were conducted evaluating automatic subsurface feeders; natural diets; exercise systems; seminatural raceway habitat enriched with cover, structure, and substrate; and predator avoidance conditioning for hatchery salmonids. Automatic subsurface feed delivery systems did not affect chinook salmon depth distribution or vulnerability to avian predators. Live-food diets only marginally improved the ability of chinook salmon to capture prey in stream enclosures. A prototype exercise system that can be retrofitted to raceways was developed, however, initial testing indicated that severe amounts of exercise may increase in culture mortality. Rearing chinook salmon in seminatural raceway habitat with gravel substrate, woody debris structure, and overhead cover improved coloration and postrelease survival without impacting in-culture health or survival. Steelhead fry reared in enriched environments with structure, cover, and point source feeders dominated and outcompeted conventionally reared fish. Exposing chinook salmon to caged predators increased their postrelease survival. Chinook salmon showed an antipredator response to chemical stimuli from injured conspecifics and exhibited acquired predator recognition following exposure to paired predator-prey stimuli. The report also includes the 1997 Natural Rearing System Workshop proceedings.

    This study examined the haemolytic effects of an interval-based running task in fore-foot and rear-foot striking runners. Nineteen male distance runners (10 fore-foot, 9 rear-foot) completed 8 × 3 min repeats at 90% vVO2peak on a motorised treadmill. Pre- and post-exercise venous blood samples were analysed for serum haptoglobin to quantify the haemolytic response to running. Vertical ground reaction forces were also captured via a force plate beneath the treadmill belt. Haptoglobin levels were significantly decreased following exercise (P = 0.001) in both groups (but not between groups), suggesting that the running task created a haemolytic stress. The ground reaction force data showed strong effect sizes for a greater peak force (d = 1.20) and impulse (d = 1.37) in fore-foot runners, and a greater rate of force development (d = 2.74) in rear-foot runners. The lack of difference in haptoglobin response between groups may be explained by the trend for fore-foot runners to experience greater peak force and impulse during the stance phase of their running gait, potentially negating any impact of the greater rate of force development occurring from the rear-foot runners' heel strike. Neither type of runner (fore-foot or rear-foot) appears more susceptible to technique-related foot-strike haemolysis. PMID:26618486

  5. Rearing technique and biological traits of Atheloca subrufella (Hulst) (Lepidoptera: Phycitidae) in coconut fruits

    International Nuclear Information System (INIS)

    Larvae of the coconut moth Atheloca subrufella (Hulst) develop in flowers and fruits of coconut, Cocos nucifera, causing precocious abscission of these structures and, hence, yield decrease. This work studied a feasible and suitable rearing technique for A. subrufella using fruits of coconut. We first determined the appropriate density of larvae to be reared per coconut fruit (among two, three, four or five larvae) and later tested the suitability of this rearing technique for three successive generations. The storage of egg and pupal stages during 0, 5, 10 and 20 days was also studied at 12 deg C. Based on the fertility life table parameters, the best results were achieved by rearing two or three larvae per fruit as they yielded the best net reproductive rate and intrinsic rate of population increase. In addition, eggs and pupae of A. subrufella can be stored at 12 deg C up to five days with viability higher than 90%. Adult moths emerged from pupae stored for five days at 12 deg C produced an average of 219.4 eggs and lived 18.8 days. Storage periods for eggs and pupae over 10 days significantly reduced egg viability and adult fecundity, respectively. Thus, the technique in here described was shown to be suitable for the continuous rearing of A. subrufella in laboratory conditions. (author)

    Full Text Available To investigate the effects of genotype and rearing system on innate immunity and oxidative status, 40 weaned commercial hybrid (H rabbits and 40 rabbits of a local population (LP were assigned to two rearing systems: cage (17 rabbits/m2 and pen (1x2 m, 10 rabbits/m2. Rearing H rabbits in pen resulted in a higher lysozyme concentration (P<0.05, an increased bactericidal ac- tivity (P<0.05 and a lower complement haemolytic activity (P<0.05 with respect to those reared in cage. Opposite results were obtained for LP rabbits. In addition, genotype H was more susceptibility to inflammation than LP in pen, whereas genotype LP suffered more in cage. A higher lipid (P<0.05 and protein (P<0.05 oxidation was found in Longissimus dorsi and Biceps femoris of rabbits H in pen compared to those in cage. An opposite trend was observed for LP rabbits. In cage, LP rabbits were more susceptible to oxidative stress than H rabbits. Taken together, our results show that immune and oxidative resistance ascribed to a specific genotype are important factors to be considered when a specific rearing system should be adopted. Considering this, rabbit LP seem to better adapt to larger spaces during growing.

  7. Interaction of rearing environment and reproductive tactic on gene expression profiles in Atlantic salmon

    Organisms that share the same genotype can develop into divergent phenotypes, depending on environmental conditions. In Atlantic salmon, young males of the same age can be found either as sneakers or immature males that are future anadromous fish. Just as the organism-level phenotype varies between divergent male developmental trajectories, brain gene expression is expected to vary as well. We hypothesized that rearing environment can also have an important effect on gene expression in the brain and possibly interact with the reproductive tactic adopted. We tested this hypothesis by comparing brain gene expression profiles of the two male tactics in fish from the same population that were reared in either a natural stream or under laboratory conditions. We found that expression of certain genes was affected by rearing environment only, while others varied between male reproductive tactics independent of rearing environment. Finally, more than half of all genes that showed variable expression varied between the two male tactics only in one environment. Thus, in these fish, very different molecular pathways can give rise to similar macro-phenotypes depending on rearing environment. This result gives important insights into the molecular underpinnings of developmental plasticity in relationship to the environment. ?? 2005 The American Genetic Association.

  8. Improvements on Rearing Procedures and its Benefits to Fly Production for SIT Application

    International Nuclear Information System (INIS)

    The status of tsetse mass rearing relative to that which has been developed for other SIT targeted pest, is a major constrain for the wider application of this technique for tsetse. Being K selected and obligate haematophagous, the reproduction rate is very low and in nature they are adapted to feed on sterile blood obtained directly from blood vessels of host animals. So, cleanliness in the lab and in vitro feeding equipment is important for tsetse survival and reproduction. Also, fly handling procedures have to be reduced in number and scope to enable a more economic production of flies to be accomplished. Traditional tsetse rearing procedures were described by Nash et al., (1968) and Tarimo et al., (1984). However in order to have excess males for release on Zanzibar, several improvements had to be done to improve the rearing conditions in order to have a steady producing colony for production of quality sterilized males. Years of rearing at TTRI, plus the collaboration with the Tsetse group at Seibersdorf has demonstrated that many procedures can be simplified without compromising fly production and quality. Several of these procedures were adopted for G. austeni colony and enabled the increase in colony size, increased pupae production which led to the increase in excess males for release. The end result was the successful eradication of G. austeni in Unguja Island (Msangi et al, 2000). Factors behind the success in tsetse rearing in Tanga are reviewed below.

    The National Marine Fisheries Service (NMFS) Northwest Fisheries Science Center, in cooperation with the Idaho Department of Fish and Game and the Bonneville Power Administration, has established captive broodstock and captive rearing programs to aid recovery of Snake River sockeye salmon (Oncorhynchus nerka) listed as endangered under the U.S. Endangered Species Act (ESA). Captive broodstock and captive rearing programs are a form of artificial propagation that are emerging as an important component of restoration efforts for ESA-listed salmon populations that are at critically low numbers. Captive broodstocks, reared in captivity for the entire life cycle, couple the salmon's high fecundity with potentially high survival in protective culture to produce large numbers of juveniles in a single generation for supplementation of natural populations. The captive broodstocks discussed in this report were intended to protect the last known remnants of sockeye salmon that return to Redfish Lake in the Sawtooth Basin of Idaho at the headwaters of the Salmon River. This report addresses NMFS research from 1 September 2000 to 31 August 2001 on the Redfish Lake sockeye salmon captive broodstock and captive rearing program. NMFS currently has broodstock in culture from year classes 1997, 1998, 1999, and 2000 in both the captive broodstock and captive rearing programs. Offspring from these programs are being returned to Idaho to aid recovery efforts for the species.

  10. [Conscious instead of instinctive behavior: efficient replacement of the mother-child relationship in residential nurseries].

    Falk, J

    1980-01-01

    When the mother of the human baby must be permanently replaced, a solution must be found which is not based upon the spontaneous behavior of the substitute. The nurse-child relationship in any residential nursery, efficiently replacing the mother-child relationship, differs from that relation in its essential characteristics. The origins, motivation and the elements composing the relationship are different, as well as its future. Any demand on the nurse to assume an attitude similar to the instinctive maternal one is false and dangerous. While intensifying the personal characteristics of care, the nurse should always keep in mind that it is not her own child she is rearing. In spite of her devotion, feelings and affectionate exchanges with the child, she must consciously remain in line with her profession. While showing warmth to all the children in her guard, the residential nursery nurse must control her attachment to prevent the children from becoming objects of her unlimited and uncontrolled emotions. The results of catamnestic studies on former pupils of the Loczy Institute in Budapest seem to prove that the institutional model used protects the child from serious deficiencies, insures good development and organization of the personality and gives him a good basis for relationships with other people.

    2007-01-01

    The Shanxi Province child labor scandal has shocked China to its core. Over 1,000 children were forced into illegal labor by morally bankrupt brick kiln businesses, throwing a depressing shroud over China’s rapid development. Uncovering these tales of abduction, death and the physical and mental abuse endured by these children has been a proud moment for China’s press. Several hundred of the kiln slave children have now been reunited with their families. Kiln owners, contractors and accomplices are being brought to justice or hunted down, some even charged with murder.However, in all this gloom some good has surfaced.Public and government attention is now focused on erasing child labor once and for all and for better protecting workers’ rights, hopefully ridding China of such disgraces in the future.

    Immigrant and native child poverty in Denmark, Norway, and Sweden 1993–2001 is studied using large sets of panel data. While native children face yearly poverty risks of less than 10 percent in all three countries and for all years studied the increasing proportion of immigrant children...... with an origin in middle- and low-income countries have poverty risks that vary from 38 up to as much as 58 percent. At the end of the observation period, one third of the poor children in Norway and as high as about a half in Denmark and in Sweden are of immigrant origin. The strong overrepresentation...... of immigrant children from low- and middle-income countries when measured in yearly data is also found when applying a longer accounting period for poverty measurement. We find that child poverty rates are generally high shortly after arrival to the new country and typically decrease with years since...

  15. Cohabitation and Child Wellbeing.

    Science.gov (United States)

    Manning, Wendy D

    2015-01-01

    In recent decades, writes Wendy Manning, cohabitation has become a central part of the family landscape in the United States-so much so that by age 12, 40 percent of American children will have spent at least part of their lives in a cohabiting household. Although many children are born to cohabiting parents, and cohabiting families come in other forms as well, the most common cohabiting arrangement is a biological mother and a male partner. Cohabitation, Manning notes, is associated with several factors that have the potential to reduce children's wellbeing. Cohabiting families are more likely than married families to be poor, and poverty harms children in many ways. Cohabiting parents also tend to have less formal education-a key indicator of both economic and social resources-than married parents do. And cohabiting parent families don't have the same legal protections that married parent families have. Most importantly, cohabitation is often a marker of family instability, and family instability is strongly associated with poorer outcomes for children. Children born to cohabiting parents see their parents break up more often than do children born to married parents. In this way, being born into a cohabiting family sets the stage for later instability, and children who are born to cohabiting parents appear to experience enduring deficits of psychosocial wellbeing. On the other hand, stable cohabiting families with two biological parents seem to offer many of the same health, cognitive, and behavioral benefits that stable married biological parent families provide. Turning to stepfamilies, cohabitation's effects are tied to a child's age. Among young children, living in a cohabiting stepfamily rather than a married stepfamily is associated with more negative indicators of child wellbeing, but this is not so among adolescents. Thus the link between parental cohabitation and child wellbeing depends on both the type of cohabiting parent family and the age of the

  19. Mass rearing of the oriental tobacco budworm for sterile insect technique programs

    International Nuclear Information System (INIS)

    The main purpose of the study is to find out a proper technique for mass rearing the oriental tobacco budworm, Helicoverpa assulta Guenee. The oriental tobacco budworms larvae were reared with different formulation diets and kept in traditional glass test tubes or in specially-designed cell-unit devices. When the diets including vitamin C and tomato source, and the ratio of corn and soybean powder was set as 1:2, the pupae weight, moth weight, pupation, emergence, fecundity and hatchability were increased significantly. When reared in cell-units, there is no significant difference in insect compared with those in glass test tubes, but the production efficiency was much higher and the cost was lower than the latter. The results of this study provide a key technical support for the application of sterile insect technique in control of oriental tobacco budworm. (authors)

    Numerical investigation was performed to examine the effect of rear barrier pillar on stress distribution around a longwall face. Salamon theoretical formula was used to calculate the parameters of the caving zone, which was later assigned to double yield constitutive model in FLAC3 D. Numerical results demonstrate that high stress concentration zone exists above the region where the second open-off cut intersects with the rear barrier pillar due to stress transfer and plastic zone expansion. It is also found that the maximum vertical stresses with varied distance to the seam floor are all within the projective plane of the rear barrier pillar and their positions concentrate on the barrier pillar adjacent to the connection corner of the second open-off cut. In addition, position of the maximum vertical stresses abruptly transfer from the connection corner adjacent to former panel to that adjacent to current panel along the panel direction.

    Full Text Available In this study the relationship of parental self-esteem, parental rearing and adolescent adult attachment was investigated. A total 448 senior high school students completed EMBU(Egna Minnen av Barndoms Uppfostran, or ―Own memories of parental rearing‖, Perris et al., 1980, the Experiences in Close Relationships Scale (ECR; Brennan, Clark, &Shaver, 1998, and their parents completed The Rosenberg Self-Esteem Scale (SES; Rosenberg, 1965. The results suggested that parental global self-esteem has no effect on the adolescent attachment to parents. Parental positive rearing behaviors have been significantly associated with avoidance to parents. Furthermore, the negative rearing behaviors, such as paternal denying and rejecting, maternal punitiveness, maternal overinvolved and overprotective behavior, can predict the adolescent avoidance and anxiety to parents.

  3. Rear wheel torque vectoring model predictive control with velocity regulation for electric vehicles

    2015-11-01

    In this paper we propose a constrained optimal control architecture for combined velocity, yaw and sideslip regulation for stabilisation of the vehicle near the limit of lateral acceleration using the rear axle electric torque vectoring configuration of an electric vehicle. A nonlinear vehicle and tyre model are used to find reference steady-state cornering conditions and design two model predictive control (MPC) strategies of different levels of fidelity: one that uses a linearised version of the full vehicle model with the rear wheels' torques as the input, and another one that neglects the wheel dynamics and uses the rear wheels' slips as the input instead. After analysing the relative trade-offs between performance and computational effort, we compare the two MPC strategies against each other and against an unconstrained optimal control strategy in Simulink and Carsim environment.

    Full Text Available Morphometric changes of A1, A1' and A2 protocerebral dorsomedial neurosecretory neurons, total brain protein content and brain protein profiles were analyzed in 4th instar Lymantria dispar larvae under elevated rearing density, i.e. under intense stress when 5 larvae were kept in a petri dish (V = 80 ml, less intense stress when 5 larvae were kept in a plastic cup (V = 300 ml. In the control samples the larvae were reared in isolated conditions. Protein pattern changes in the brain were observed. Proteins with the following molecular masses: 30, 14, 10 and 3.4-2.5 kD were detected in the experimental groups. The size and cytological characteristics of protocerebral dorsomedial neurosecretory neurons were changed under elevated rearing density.

    2015-06-01

    Rear impact collisions are mostly low severity, but carry a very high societal cost due to reported symptoms of whiplash and related soft tissue injuries. Given the difficulty in physiological measurement of damage in whiplash patients, there is a significant need to assess rear impact severity on the basis of vehicle damage. This paper presents fundamental impact equations on the basis of an equivalent single vehicle to rigid barrier collision in order to predict relationships between impact speed, maximum dynamic crush, mean and peak acceleration, time to common velocity and vehicle stiffness. These are then applied in regression analysis of published staged low speed rear impact tests. The equivalent mean and peak accelerations are linear functions of the collision closing speed, while the time to common velocity is independent of the collision closing speed. Furthermore, the time to common velocity can be used as a surrogate measure of the normalized vehicle stiffness, which provides opportunity for future accident reconstruction.

    Body weights of rat pups reared during exposure to hypergravity (hg) are significantly reduced relative to 1 g controls. In the present study, we examined in hg-reared rat pups two major contributors to growth and development, namely growth hormone (GH) and insulin-like growth factor-1 (IGF-1). Beginning on Gestational day (G)11 of the rats 22 day pregnancy, rat dams and their litters were continuously exposed to either 1.5-g or 2.0-g. On Postnatal day (P)l0, plasma GH and IGF-1 were analyzed using radioimmunoassay (RIA). Both hormones were significantly elevated in hg pups relative to 1-g control pups. Together, these findings suggest that GH and IGF-1 are not primary determinants of reduced body weights observed in hg-reared pups. The significant elevations in pup GH and IGF-1 may be related to increased physical stimulation in hypergravity.

    Despite significant reductions in the number of children killed in motor vehicle crashes over the past decade, crashes continue to be the leading cause of death for children 4 years and older. Therefore, the American Academy of Pediatrics continues to recommend inclusion of child passenger safety anticipatory guidance at every health-supervision visit. This technical report provides a summary of the evidence in support of 5 recommendations for best practices to optimize safety in passenger vehicles for children from birth through adolescence that all pediatricians should know and promote in their routine practice. These recommendations are presented in the revised policy statement on child passenger safety in the form of an algorithm that is intended to facilitate their implementation by pediatricians with their patients and families. The algorithm is designed to cover the majority of situations that pediatricians will encounter in practice. In addition, a summary of evidence on a number of additional issues that affect the safety of children in motor vehicles, including the proper use and installation of child restraints, exposure to air bags, travel in pickup trucks, children left in or around vehicles, and the importance of restraint laws, is provided. Finally, this technical report provides pediatricians with a number of resources for additional information to use when providing anticipatory guidance to families. PMID:21422094

  11. Dispersal and longevity of wild and mass-reared Anastrepha Ludens and Anastrepha Obliqua (Diptera: Tephritidae)

    International Nuclear Information System (INIS)

    The rates of dispersal and survival of sterile mass-reared laboratory flies and sterile wild flies of Anastrepha ludens (Loew) and Anastrepha obliqua (Macquart) were estimated and compared with a regular rectangular array of 64 food-baited traps spaced 60 m between traps around the release point in Tapachula Chiapas, Mexico. The traps were scored every day during the first week, and then every 3 d over a 30-d period. For A. obliqua, the number of males recaptured was higher than that of females, while for A. ludens, females were recaptured more frequently than males. The recapture rate for the wild strains ranged from 0.6-24.8% for A. ludens and 1.3-16.2% for A. obliqua and the corresponding ranges for the mass-reared strains were 0.5-7.1% and 0.5-3.0% respectively. The life expectancy was 4.7 d for wild and 4.3 d for mass-reared A. obliqua males but 3 and 2 d, respectively, for wild and mass-reared A. ludens males. The net displacement of A. ludens and A. obliqua ranged approximately from 100-250 m and took place mostly on the first day. Wild A. ludens moved to the northwest from the release point while the mass-reared strain moved to the west. The A. obliqua wild flies moved to the west, while the mass-reared strain shifted to the southwest. We discuss the implications of our findings as to the spacing and frequency of sterile fly releases for the suppression of wild populations. (author)

    For Pacific salmon, estuaries are typically considered transitional staging areas between freshwater and marine environments, but their potential as rearing habitat has only recently been recognized. The objectives of this study were two-fold: (1) to determine if Coho Salmon Oncorhynchus kisutch were rearing in estuarine habitats, and (2) to characterize and compare the body length, age, condition, and duration and timing of estuarine occupancy of juvenile Coho Salmon between the two contrasting estuaries. We examined use of estuary habitats with analysis of microchemistry and microstructure of sagittal otoliths in two watersheds of south-central Alaska. Juvenile Coho Salmon were classified as estuary residents or nonresidents (recent estuary immigrants) based on otolith Sr : Ca ratios and counts of daily growth increments on otoliths. The estuaries differed in water source (glacial versus snowmelt hydrographs) and in relative estuarine and watershed area. Juvenile Coho Salmon with evidence of estuary rearing were greater in body length and condition than individuals lacking evidence of estuarine rearing. Coho Salmon captured in the glacial estuary had greater variability in body length and condition, and younger age-classes predominated the catch compared with the nearby snowmelt-fed, smaller estuary. Estuary-rearing fish in the glacial estuary arrived later and remained longer (39 versus 24 d of summer growth) during the summer than did fish using the snowmelt estuary. Finally, we observed definitive patterns of overwintering in estuarine and near shore environments in both estuaries. Evidence of estuary rearing and overwintering with differences in fish traits among contrasting estuary types refute the notion that estuaries function as only staging or transitional habitats in the early life history of Coho Salmon.

  13. Effects of Hypergravity Rearing on Growth Hormone (GH) Secretion In Preweanling Rats

    We previously reported that rat pups reared at 1.5-g, 1.75 or 2.0-g hypergravity weigh 6-15% less than 1.0-g controls. To account for these findings. we measured the lactational hormones, prolaction (Prl) and oxytocin (OT), in the pups' mothers. Gravity related differences in Prl were not observed whereas OT of lactating dams was significantly reduced relative to controls. Milk transfer from dam to pup was not impaired in hypergravity-reared litters tested at 1-g. Together, these findings suggest that impaired lactation and milk transfer do not account for reduced body masses of postnatal rats reared in hypergravity. In the present study, we analyzed growth hormone (GH) secretion and maternal licking in pups reared in hypergravity and in 1.0-g controls. Recent reports using dwarfing phenotypes in mouse mutants have provided evidence for postnatal dependence on GH and insulin-like growth factors (IGFs). Beginning on Gestational day (G)11 of the rats' 22 day pregnancy, rat dams and their litters were exposed to either 1.5-g, 1.75-g or 2.0-g. On Postnatal day (P)10, we measured plasma GH using enzyme immunoassay (EIA). Contrary to our hypothesis, GH was significantly elevated in pups reared at 2.0-g relative to 1.0-g controls. Pup-oriented behaviors of the hypergravity dams were also changed, possibly accounting for the increase in pup GH. GH alone does not appear to play a role in reduced body weights of hypergravity-reared pups.

    Full Text Available In this paper, a rear-end collision control model is proposed using the fuzzy logic control scheme for the autonomous or cruising vehicles in Intelligent Transportation Systems (ITSs. Through detailed analysis of the car-following cases, our controller is established on some reasonable control rules. In addition, to refine the initialized fuzzy rules considering characteristics of the rear-end collisions, the genetic algorithm is introduced to reduce the computational complexity while maintaining accuracy. Numerical results indicate that our Genetic algorithm-optimized Fuzzy Logic Controller (GFLC outperforms the traditional fuzzy logic controller in terms of better safety guarantee and higher traffic efficiency.

    The bacteria in the genus Vibrio are heterothrophic, which exist in the larval rearing water of Crustacea and often show diverse pathogenicities to marine animals. In order to assess the bacterial diversity associated with Crustacean seed production, 32 strains were isolated from black tiger shrimp (Penaeus monodon ) and mangrove crab (Scylla paramamosain ) larvae and their rearing-water and characterized using biochemical and molecular approaches. Two or more genotypically different species were identified. The vibriosis of black tiger shrimp was caused by V. harveyi, V. alginolyticus and Vibrio spp.predominantly, while that of crab by V. harveyi and V. alginolyticus only.

    The perceived parental rearing practices and attitudes of social phobics, agoraphobics, height phobics and non-patient normal controls were investigated, employing the EMBU, an inventory for assessing memories of upbringing. Findings revealed that, as compared with the controls, social phobics and height phobics scored both parents not only as lacking in emotional warmth, but also as having been rejective and overprotective. Agoraphobics reported both parents as having lacked emotional warmth, but only their mothers as being rejecting. Interestingly, the perception of negative rearing practices of parents appeared to be stronger in height phobics than in either social phobics or agoraphobics. PMID:6616119

    The aim of the present work is to passively reduce the induced drag of the rear wing of a Formula One car at high velocity through aeroelastic tailoring. The angle-of-attack of the rear wing is fixed and is determined by the required downforce needed to get around a turn. As a result, at higher velocity, the amount of downforce and related induced drag increases. The maximum speed on a straight part is thus reduced due to the increase in induced drag.

    In schema therapy (ST), early maladaptive schemas (EMS) are proposed to be the defining core of personality disorders. Adverse relational experiences in childhood are assumed to be the main cause for the development of EMS. The present study explored the links between perceived parental rearing behaviours, EMS, and personality disorder symptoms in a clinical sample (N=108). Results from mediation analyses suggest that EMS mediate the relationships between recalled parenting rearing behaviours and personality disorder symptoms. Findings give support to the theoretical model ST is based on.

  4. Does rearing laying hens in aviaries adversely affect long-term welfare following transfer to furnished cages?

    Directory of Open Access Journals (Sweden)

    Fernanda M Tahamtani

    Full Text Available This study tests the hypothesis that hens that are reared in aviaries but produce in furnished cages experience poorer welfare in production than hens reared in caged systems. This hypothesis is based on the suggestion that the spatial restriction associated with the transfer from aviaries to cages results in frustration or stress for the aviary reared birds. To assess the difference in welfare between aviary and cage reared hens in production, non-beak trimmed white leghorn birds from both rearing backgrounds were filmed at a commercial farm that used furnished cage housing. The videos were taken at 19 and 21 weeks of age, following the birds' transition to the production environment at 16 weeks. Videos were analysed in terms of the performance of aversion-related behaviour in undisturbed birds, comfort behaviour in undisturbed birds, and alert behaviour directed to a novel object in the home cage. A decrease in the performance of the former behaviour and increase in the performance of the latter two behaviours indicates improved welfare. The results showed that aviary reared birds performed more alert behaviour near to the object than did cage reared birds at 19 but not at 21 weeks of age (P = 0.03. Blood glucose concentrations did not differ between the treatments (P>0.10. There was a significant difference in mortality between treatments (P = 0.000, with more death in aviary reared birds (5.52% compared to cage birds (2.48%. The higher mortality of aviary-reared birds indicates a negative effect of aviary rearing on bird welfare, whereas the higher duration of alert behavior suggests a positive effect of aviary rearing.

    The death of a child is a sentinel event in a community, and a defining marker of a society's policies of safety and health. Child death as a result of abuse and neglect is a tragic outcome that occurs in all nations of the world. The true incidence of fatal child abuse and neglect is unknown. The most accurate incidence data of such deaths have been obtained from countries where multi‐agency death review teams analyse the causes of child fatalities, as is done in the United States and Austra...

    Passage of the Adoption and Safe Families Act of 1997 has placed the child at the center of the child welfare system. Courts bear the ultimate responsibility for the safety and well-being of these children, including those with disabilities. Findings from the Child and Family Service Reviews, however, indicate less-than-optimal conformity in a number of states regarding the physical and mental well-being of children. A multidisciplinary approach involving jurisprudence, science, and financing is required to bring about better compliance. Collaboration among legal, medical, dental, and child advocacy organizations is necessary for healing children in the welfare system to become a national imperative. PMID:17566535

    Objective To study the characteristics of college students' empathy and parental rearing patterns,as well as the mutual influence between them. Methods Six hundred and three medical students served as the samples and tested by using the parental rearing patterns ( Egma Minnen av Bardndosnauppforstran, EMBU) and Interpersonal Reactivity Index (IRI). Results Boys scored lower than girls on parental emotional warmth and understanding, refusal and deny, but boys scored higher than girls on paternal stern punishment and overprotection. The only-child scored higher than the non-only-child on parental over intervention and maternal emotional warmth and understanding and stern punishment, but the only child scored lower than non-only child on paternal partiality. The urban students scored higher than the rural on parental emotional warmth and understanding , but the rural ones scored higher than the urban ones on parental partiality (P<0. 05 ). The boys scored lower than girls on imagination, empathy concerns and personal pains; the only-child- scored lower than the non-only-child on empathy concerns and personal pains; the urban students scored lower than the rural ones on empathy concerns) P<0. 01). Parental rearing patterns were obviously correlated with some factors of IRI.

    Previous investigations of the linguistic capacities of apes have focused on the ape's ability to produce words, and there has been little concern for comprehension. By contrast, it is increasingly recognized that comprehension precedes production in the language development of normal human children, and it may indeed guide production. It has been demonstrated that some species can process speech sounds categorically in a manner similar to that observed in humans. Consequently, it should be possible for such species to comprehend language if they have the cognitive capacity to understand word-referent relations and syntactic structure. Popular theories of human language acquisition suggest that the ability to process syntactic information is unique to humans and reflects a novel biological adaptation not seen in other animals. The current report addresses this issue through systematic experimental comparisons of the language comprehension skills of a 2-year-old child and an 8 year-old bonobo (Pan paniscus) who was raised in a language environment similar to that in which children are raised but specifically modified to be appropriate for an ape. Both subjects (child and bonobo) were exposed to spoken English and lexigrams from infancy, and neither was trained to comprehend speech. A common caretaker participated in the rearing of both subjects. All language acquisition was through observational learning. Without prior training, subjects were asked to respond to the same 660 novel sentences. All responses were videotaped and scored for accuracy of comprehension of the English language. The results indicated that both subjects comprehended novel requests and simple syntactic devices. The bonobo decoded the syntactic device of word recursion with higher accuracy than the child; however, the child tended to do better than the bonobo on the conjunctive, a structure that places a greater burden on short-term memory. Both subjects performed as well on sentences that

  20. Child sexual abuse

    International Nuclear Information System (INIS)

    Background: Child sexual abuse with significant impact on victim's physical, mental and social health has now been recognized as existing on an appreciable scale worldwide. Diversity of opinions exist about the concept, types, prevalence and repercussions along with a paucity of systematic and scientific work in the developing world including Pakistan. Objective: This paper aims at reviewing the literature for clarification of concept, update of estimates and correlates, and to identify lines for future research. Data sources: The literature was search through BMJ-Medline for international data, supplemented by local data through CPSP-MEDLIP service. The search term child sexual abuse with associated sub-heads were used. No constraint of time period, publication type or source applied except english Language version Comparative findings: Wide variations identified in conceptual boundaries with consequent impact on prevalence estimates. Agreement found for its existence as an international problem with rates ranging from 7% - 36% for women and 3% - 29% for men. Female abused 1.5-3 times more than male with exponential high rates in age group 3-6 years and 8-11 years. In 2/3 cases the perpetrator identified belonged to nuclear or extended family. Significant association exists with early onset of psychiatric ailments like substance abuse, eating disorders, personality disorders, dissociative disorders and depression. Conclusion and Suggestion: The need for extensive research studies in immense in developing countries like Pakistan where environmental circumstances suggest its presence at rates higher than the identified elsewhere. In addition to facilitate awareness and perhaps to clarify the concept as well as the prevalence of child sexual abuse researchers need to select methodologies and instruments with international comparison in mind.

    Colombia is a country with major problems, mainly a high degree of inequality and an unacceptably high level of violence (both armed military conflict and crime related). There are unacceptably high variations in health and health provision. Despite these difficulties, there are important steps being taken by both the government and independent organisations to try and improve child health and to achieve the Millennium Development Goals in relation to poverty, hunger and health issues. The participation of different sectors and stakeholders (including government, non-governmental organisations and other organisations of civil society) is essential to overcome Colombian history and to promote a better place for children.

In the control group, single larvae were reared in a Petri dish. Morphometric changes in L1, L2 and L2’ dorsolateral neurosecretory neurons (nsn were analyzed. After keeping 5 larvae in a Petri dish, the size of L2 neurosecretory neurons (nsn significantly increased. Rearing 5 larvae in a plastic cup significantly increased the size of L1 nsn nuclei and the number of L2’nsn. A decrease in relative band densities in the region of molecular masses (11-15 kD that correspond to prothoracicotropic hormones in the gypsy moth was observed in the electrophoretic profiles that were obtained after both treatments in comparison to the control group.

    2012-12-01

    Full Text Available Ceratitis capitata is one of the most important pests of fruits for exportation, and Sterile Insect Technique (SIT has been the most efficient and environmental friendly technique used to control fruit fly populations around the world. A key goal in achieving a successful SIT program is a mass rearing system producing high quality insects at low cost. Providing adults with an artificial diet containing hydrolysed protein has been the major obstacle for bio-production facilities in Brazil, because it is expensive and has to be imported. Two other commercial products, autolysed yeast (AY and yeast extract (YE, of domestic origin and low cost, were tested as substitutes of the imported hydrolyzed protein. To compare their efficiency we observed the female fecundity, adult survival and egg viability of flies raised on diets containing one of each of the different protein products. Flies reared on the domestic yeast products had equivalent or superior performance to the flies reared on imported protein. Both AY and YE can be a possible substitute for imported hydrolyzed protein for C. capitata mass-rearing, as they are cheaper and are readily available in the national market.

    2014-08-01

    Full Text Available Some species of the genus Anastrepha (Diptera: Tephritidae are successfully managed by matching the sterile insect technique with parasitoid releases. Such strategies used in integrated pest management can be implemented only where insect mass-rearing programs are feasible. In this study, we show the process of domestication, rearing technology and quality control data obtained from 54 generations of Anastrepha sp.1 aff. fraterculus (Wiedemann, 1830 kept under fully artificial conditions. Eggs were collected by an artificial oviposition panel consisting of one side of the cage made of blue voile fabric externally covered with a thin layer of silicon rubber. They were then air-bubbled in water at 25 ºC for 48 h before seeding. Larvae were reared on the regular laboratory artificial diet with 66 % of agar reduction turning over a semi-liquid diet, which reduced costs and improved insect quality. The adult and larval diets were composed of local ingredients including hydrolyzed yeast. When large-scale production of this fly is contemplated, the critical stage is larval development. This system of artificial rearing for A. fraterculus sp.1 developed in Brazil, allows for the production of a large number of insects of excellent quality using local ingredients and less agar in diet composition than the original medium used for this species. By reducing the interval of egg collection, the system might be optimized in terms of insect yield and, therefore, meet the demands of A. fraterculus sp.1 with regard to integrated pest management purposes.

    Wildlife managers are challenged with the task of deciding whether a management measure is appropriate or not, and furthermore they have to convince others about the merits of their decision. Population decline of some hare species (genus Lepus) has resulted in their Red Listing and conservation measures are being undertaken. Release or restocking is a frequent measure in some countries, and thousands of hares are released annually, mainly for hunting purposes. These hares can be obtained by either intensive or extensive rearing or translocation of the wild animals. Each method entails difficulties and different survival rates in the wild. Survival rates in the wild are low for hares intensively reared in cages but are higher for hares reared extensively in enclosures and wild translocated hares. The benefits of the hare release practice are significantly lower than the action's implementation cost. Hare releases have not increased significantly the wild hare population or the hunting harvest in areas where the practice has been applied. The risk of genetic and evolutionary degradation and pathogen transmission is possible in wild populations. The need for wise management of this practice is evident and the term `Permitted Transferring Units' should be introduced to denote regions where hares should not be transferred for rearing and release.

    In this report, the National Marine Fisheries Service (NMFS), in collaboration with the Bonneville Power Administration (BPA), the Washington State Department of Fish and Wildlife (WDFW), and the US Fish and Wildlife Service (USFWS), presents research findings and guidelines for development and evaluation of innovative culture techniques to increase postrelease survival of hatchery fish. The Natural Rearing Enhancement System (NATURES) described in this report is a collection of experimental approaches designed to produce hatchery-reared chinook salmon (Oncorhynchus tshawytscha) that exhibit wild-like behavior, physiology, and morphology. The NATURES culture research for salmonids included multiple tests to develop techniques such as: raceways equipped with cover, structure, and natural substrates to promote development of proper body camouflage coloration; feed-delivery systems that condition fish to orient to the bottom rather than the surface of the rearing vessel; predator conditioning of fish to train them to avoid predators; and supplementing diets with natural live foods to improve foraging ability. The underlying assumptions are that NATURES will: (1) promote the development of natural cryptic coloration and antipredator behavior; (2) increase postrelease foraging efficiency; (3) improve fish health and condition by alleviating chronic, artificial rearing habitat-induced stress; and (4) reduce potential genetic selection pressures induced by the conventional salmon culture environment. A goal in using NATURES is to provide quality fish for rebuilding depleted natural runs.

Posture-prediction models for female and male passengers were separately developed by stepwise regression using age, body dimensions, seat configurations and two-way interactions as potential predictors. Passenger posture was significantly associated with age and the effects of other two-way interaction variables depended on age. A set of posture-prediction models are presented for women and men, and the prediction results are compared with previously published models. This study is the first study of passenger posture to include a large cohort of older passengers and the first to report a significant effect of age for adults. The presented models can be used to position computational and physical human models for vehicle design and assessment. Practitioner Summary: The significant effects of age, body dimensions and seat configuration on rear seat passenger posture were identified. The models can be used to accurately position computational human models or crash test dummies for older passengers in known rear seat configurations.

  20. Reconstruction of Low Speed Rear-End collisions - Technical Means of Assessing Cervical Spine Injuries

    OpenAIRE

    Hitzemann, Martin

    2003-01-01

    In recent years, an increasing number of cervical spine injuries sustained by vehicle occupants in collisions at comparatively low speeds have been reported to insurance companies and in civil litigation. The reported injuries occur in both rear-end and side impact collisions. The paper describes how a detailed assessment of such cases requires interdisciplinary teamwork involving technical, biomechanical and medical experts.

    Few statistical models of rear seat passenger posture have been published, and none has taken into account the effects of occupant age. This study developed new statistical models for predicting passenger postures in the rear seats of automobiles. Postures of 89 adults with a wide range of age and body size were measured in a laboratory mock-up in seven seat configurations. Posture-prediction models for female and male passengers were separately developed by stepwise regression using age, body dimensions, seat configurations and two-way interactions as potential predictors. Passenger posture was significantly associated with age and the effects of other two-way interaction variables depended on age. A set of posture-prediction models are presented for women and men, and the prediction results are compared with previously published models.

    1987-01-01

    Four solar cell types of current manufacture were irradiated through the front and rear surfaces with protons in the energy range between 1 and 10 MeV. The solar cell parameters varied for this study were cell thickness and back surface field (BSF) vs. no BSF. Some cells were irradiated at normal incidence and an equal number were irradiated with simulated isotropic fluences. The solar cell electrical characteristics were measured under simulated AM0 illumination after each fluence. Using the normal incidence data, proton damage coefficients were computed for all four types of cells for both normal and omnidirectional radiation fields. These were found to compare well with the omnidirectional damage coefficients derived directly from the rear-incidence radiation data. Similarly, the rear-incidence omnidirectional radiation data were used to compute appropriate damage coefficients. A method for calculating the effect of a spectrum of energies is derived from these calculations. It is suitable for calculating the degradation of cells in space when they have minimal rear-surface shielding.

    2003-04-01

    The National Marine Fisheries Service (NMFS) Northwest Fisheries Science Center, in cooperation with the Idaho Department of Fish and Game and the Bonneville Power Administration, has established captive broodstock programs to aid recovery of Snake River sockeye salmon (Oncorhynchus nerka) listed as endangered under the U.S. Endangered Species Act (ESA). Captive broodstock and captive rearing programs are a form of artificial propagation that are emerging as an important component of restoration efforts for ESA-listed salmon populations that are at critically low numbers. Captive broodstocks, reared in captivity for the entire life cycle, couple the salmon's high fecundity with potentially high survival in protective culture to produce large numbers of juveniles in a single generation for supplementation of natural populations. The captive broodstocks discussed in this report were intended to protect the last known remnants of sockeye salmon that return to Redfish Lake in the Sawtooth Basin of Idaho at the headwaters of the Salmon River. This report addresses NMFS activities from 1 September 2001 to 31 August 2002 on the Redfish Lake sockeye salmon captive broodstock and captive rearing program. NMFS currently has broodstocks in culture from year classes 1997, 1998, 1999, 2000, and 2001 in both the captive breeding and captive rearing programs. Offspring from these programs are being returned to Idaho to aid recovery efforts for the species.

  9. Cutting techniques of reinforced concrete by wire sawing rear cutting tests for separation of radioactive concrete

    International Nuclear Information System (INIS)

    The biological shielding wall of the reactor is very thick and high density reinforced concrete structures. The wall is partially activated by neutron exposure, and the activation level gradually decrease from the reactor side to outside and then the outermost side is not activated quite. Activated part and non-activated part should be separately dismantled, so that high activated and low activated area is also rationally discriminated on the point of radioactive waste management. Moreover, waste treatment and disposal of dismantled blocks will become ready to reuse or disposal in comparison with the trash from smash techniques, controlled pyrotechnical explosion, excavator and rock drill. A rear cutting technique is necessary in order to cut off the activated concrete block from the biological shielding wall. Therefore, devising and manufacturing by way of trial the unrestricted pulley, the practicability of rear cutting technique has been confirmed. On the rear cutting, wire saw has to be set up into the about 11 mm kerf width at the determined depth point. Assistant arm and pulley allowed for remote set up of the wire saw. The cutting efficiency of the rear cutting method is about 1 m2/h almost equal to the pushing method. (author)

    2014-01-01

    Full Text Available A study was carried out to determine the relationship between linear body measurements and live weight in Landrace and Large White pigs reared under different management conditions in Zimbabwe. Data was collected for body length, heart girth, and live weight in 358 pigs reared under intensive commercial conditions. The stepwise multiple linear regression method was done to develop a model using a random selection of 202 records of pigs. The model showed that age, body length, and heart girth were useful predictors of live weight in these pigs with significantly high positive correlations observed. The model was internally validated using records of the remaining 156 pigs and there was a significantly high positive correlation between the actual and predicted weights. The model was then externally validated using 40 market age pigs reared under communal conditions and there was a significantly low positive correlation between the actual and predicted weights. The results of the study show that while linear measurements can be useful in predicting pig weights the appropriateness of the model is also influenced by the management of the pigs. Models can only be applicable to pigs reared under similar conditions of management.

    The dominancy of semi-wild and hatchery-reared white-spotted charr Salvelinus leucomaenis juveniles was evaluated using pair-wise enclosure tests and field stocking tests. The semi-wild S. leucomaenis originated in a hatchery, being stocked into the test stream as eyed-eggs. In the pair-wise enclosure test, the semi-wild S. leucomaenis dominated the hatchery S. leucomaenis that were of a similar standard length (L(S) ). The semi-wild S. leucomaenis were subordinate to hatchery S. leucomaenis that were > 11% larger in LS . In the field stocking test, the abundance and growth of semi-wild S. leucomaenis was decreased in the presence of larger hatchery S. leucomaenis (14% larger LS ). Taken together, these results suggest that larger hatchery S. leucomaenis ecologically suppress the smaller semi-wild S. leucomaenis. Salvelinus leucomaenis juveniles that are stocked with the intention of supplementing natural populations should be < 10% larger than their wild counterparts at the time of stocking to minimize their competitive advantage. The semi-wild and hatchery S. leucomaenis used in both tests were genetically similar individuals, suggesting that the differences are due to the early rearing environment of either a natural stream or hatchery. The hatchery S. leucomaenis have lower levels of aggression as a result of selection in the hatchery rearing environment. Rearing in a natural stream from the eyed-egg stage is likely to increase their lowered aggression.

    2014-12-01

    Effect of rearing temperature on growth and thermal tolerance of Schizothorax (Racoma) kozlovi Nikolsky larvae and juveniles was investigated. The fish (start at 12d post hatch) were reared for nearly 6 months at five constant temperatures of 10, 14, 18, 22 and 26°C. Then juvenile fish being acclimated at three temperatures of 14, 18 and 22°C were chosen to determine their critical thermal maximum (CTMax) and lethal thermal maximum (LTMax) by using the dynamic method. Growth rate of S. kozlovi larvae and juveniles was significantly influenced by temperature and fish size, exhibiting an increase with increased rearing temperature, but a decline with increased fish size. A significant ontogenetic variation in the optimal temperatures for maximum growth were estimated to be 24.7°C and 20.6°C for larvae and juveniles of S. kozlovi, respectively. The results also demonstrated that acclimation temperature had marked effects on their CTMax and LTMax, which ranged from 32.86°C to 34.54°C and from 33.79°C to 34.80°C, respectively. It is suggested that rearing temperature must never rise above 32°C for its successful aquaculture. Significant temperature effects on the growth rate and thermal tolerance both exhibit a plasticity pattern. Determination of critical heat tolerance and optima temperature for maximum growth of S. kozlovi is of ecological significance in the conservation and aquaculture of this species.

    To reduce the risk of enteric disease in poultry, knowledge of how bird gut innate defences mature with age while also responding to different rearing environments is necessary. In this study the gut innate responses of two phylogenetically distinct lines of poultry raised from hatch to 35days, in conditions mimicing high hygiene (HH) and low hygiene (LH) rearing environments, were compared. Analyses focussed on the proximal gut antimicrobial activities and the duodenal and caecal AvBD1, 4 and 10 defensin profiles. Variability in microbial killing was observed between individual birds in each of the two lines at all ages, but samples from day 0 birds (hatch) of both lines exhibited marked killing properties, Line X: 19±11% (SEM) and Line Y: 8.5±12% (SEM). By day 7 a relaxation in killing was observed with bacterial survival increased from 3 (Line Y (LY)) to 11 (Line X (LX)) fold in birds reared in the HH environment. A less marked response was observed in the LH environment and delayed until day 14. At day 35 the gut antimicrobial properties of the two lines were comparable. The AvBD 1, 4 and 10 data relating to the duodenal and caecal tissues of day 0, 7 and 35 birds LX and LY birds revealed gene expression trends specific to each line and to the different rearing environments although the data were confounded by inter-individual variability. In summary elevated AvBD1 duodenal expression was detected in day 0 and day 7 LX, but not LY birds, maintained in LH environments; Line X and Y duodenal AvBD4 profiles were detected in day 7 birds reared in both environments although duodenal AvBD10 expression was less sensitive to bird age and rearing background. Caecal AvBD1 expression was particularly evident in newly hatched birds. These data suggest that proximal gut antimicrobial activity is related to the bird rearing environments although the roles of the AvBDs in such activities require further investigation.

  16. Hand-rearing reduces fear of humans in European starlings, Sturnus vulgaris.

    Directory of Open Access Journals (Sweden)

    Gesa Feenders

    Full Text Available Pending changes in European legislation ban the use of wild-caught animals in research. This change is partly justified on the assumption that captive-breeding (or hand-rearing increases welfare of captive animals because these practices result in animals with reduced fear of humans. However, there are few actual data on the long-term behavioural effects of captive-breeding in non-domestic species, and these are urgently needed in order to understand the welfare and scientific consequences of adopting this practice. We compared the response of hand-reared and wild-caught starlings to the presence of a human in the laboratory. During human presence, all birds increased their general locomotor activity but the wild-caught birds moved away from the human and were less active than the hand-reared birds. After the human departed, the wild-caught birds were slower to decrease their activity back towards baseline levels, and showed a dramatic increase in time at the periphery of the cage compared with the hand-reared birds. We interpret these data as showing evidence of a greater fear response in wild-caught birds with initial withdrawal followed by a subsequent rebound of prolonged attempts to escape the cage. We found no effects of environmental enrichment. However, birds in cages on low shelves were less active than birds on upper shelves, and showed a greater increase in the time spent at the periphery of their cages after the human departed, perhaps indicating that the lower cages were more stressful. In demonstrating reduced fear of humans in hand-reared birds, our results support one of the proposed welfare benefits of this practice, but without further data on the possible welfare costs of hand-rearing, it is not yet possible to reach a general conclusion about its net welfare impact. However, our results confirm a clear scientific impact of both hand-rearing and cage position at the behavioural level.

    Griest, K J; Zumwalt, R E

    1989-01-01

    Drowning as a form of subtle fatal child abuse is difficult to distinguish from accidental immersion or from sudden unexpected natural death when the circumstances of immersion are concealed. Homicidal drownings are unwitnessed, usually occurring in the home, and the victims are young, either infants or toddlers. Accidental drownings are more likely to involve toddlers or older children in public areas such as swimming pools, drainage ditches, lakes, and rivers. This is especially true in rural areas. In cities, bathtubs remain a major site of accidental childhood drownings. Perpetrators of deliberate drownings often fit the sociopathologic profile of a child abuser. Because there is often a survival interval between immersion and death, pathologic findings consistent with postimmersion syndrome suggest the cause of death. Foreign material in the lungs, if immersion was other than in clear tap water, and injuries of the face are other positive correlating factors. A thorough investigation of the circumstances and cooperation between the investigating agency and the pathologist are essential to determine the correct manner of death in these cases.

  3. Flight Muscle Development in the Males of Glossina Pallidipes Reared for the Sterile Insect Technique

    International Nuclear Information System (INIS)

    The project's main goal was to study the influence of laboratory conditions on the development of flight muscles and the ability to fly in males of Glossina pallidipes Austen. Flight muscles can serve as an important criterion in the quality control of mass reared tsetse flies. All experiments were performed in the research and training facility in Bratislava which provided the flies. The experiments were generally performed by comparing different age groups and groups with different flight activity. To acquire data, several approaches were employed, i.e. classical measurements (residual dry weight, thoracic surface) as well as other alternatives - flight mill, electron microscopy and immunohistochemistry - to visualize and analyse muscle development. The results clearly identified differences in age groups. Slight changes in the development of flight muscles regarding different chances to fly were also detected, but these were not sufficiently significant to decrease the quality of males produced in mass rearing facilities. No distinct trends (rising or declining of amount of metabolites) in the groups studied were detected. The differences were in the amount of analysed metabolic components and the structure of the flight muscles. Our results suggest that, similar to other Glossina species, in G. pallidipes males the first days after emergence are crucial for successful muscle development. On the other hand, rearing in cages does not negatively influence the quality of males with respect to their ability to fly and actively search for females in the wild after release. We also compared the mating behaviour of irradiated and non-irradiated males. We initiated the development of a functional walk-in field cage in which to rear a small colony of G. pallidipes under semi-natural conditions. Our work suggested that outside climatic conditions and suitable cage components, e.g. food source, limit the successful realization of using such a cage for rearing tsetse flies

  4. Is socioeconomic status of the rearing environment causally related to obesity in the offspring?

    Full Text Available We attempt to elucidate whether there might be a causal connection between the socioeconomic status (SES of the rearing environment and obesity in the offspring using data from two large-scale adoption studies: (1 The Copenhagen Adoption Study of Obesity (CASO, and (2 The Survey of Holt Adoptees and Their Families (HOLT. In CASO, the SES of both biological and adoptive parents was known, but all children were adopted. In HOLT, only the SES of the rearing parents was known, but the children could be either biological or adopted. After controlling for relevant covariates (e.g., adoptee age at measurement, adoptee age at transfer, adoptee sex the raw (unstandardized regression coefficients for adoptive and biological paternal SES on adoptee body mass index (BMI: kg/m(2 in CASO were -.22 and -.23, respectively, both statistically significant (p = 0.01. Controlling for parental BMI (both adoptive and biological reduced the coefficient for biological paternal SES by 44% (p = .034 and the coefficient for adoptive paternal SES by 1%. For HOLT, the regression coefficients for rearing parent SES were -.42 and -.25 for biological and adoptive children, respectively. Controlling for the average BMI of the rearing father and mother (i.e., mid-parental BMI reduced the SES coefficient by 47% in their biological offspring (p≤.0001, and by 12% in their adoptive offspring (p = .09. Thus, despite the differing structures of the two adoption studies, both suggest that shared genetic diathesis and direct environmental transmission contribute about equally to the association between rearing SES and offspring BMI.

    This is the second part of a historical review of the New Zealand child health and development record book (also known as the Well Child/Tamariki Ora Health book or Plunket book). It focuses on the years between 1945 and 2000. The first article highlighted how the book documented the development of "scientific mothering", which marginalized women-generated mothering knowledge. The present article highlights how during the reviewed time period women began to challenge notions of "scientific mothering", these changes are signaled in the content of the Well Child/Tamariki Ora Health book over time. In addition, women's movements, such as LaLeche league and Parent Centre, reflected significant societal changes during this era in relation to mothering and child-rearing practices, the influence of which had a significant impact on the Plunket book's development. However, tensions between health professionals and women in relation to the value placed on types of knowledge continued to exist as evidenced by the language employed in the Plunket books throughout the time period reviewed. Being mindful of the tensions that exist between competing discourses and knowledge sources is important as they call us to engage with how we value and develop our relationships with women and mothers as health care professionals.

    A nationwide survey in Japan on child abuse and neglect revealed that 10% of the victims were products of multiple births. None of the victims who were singletons had multiple-birth siblings, and only in a few cases were both twins abused. The findings indicated that one rather than both of a pair of twins was likely to be abused in Japan. Abuse of both twins was likely when there were serious parental or family problems, whereas abuse of one twin was associated with the child's medical problems or non-home care. There was no instance of abuse of a pair of twins when both were handicapped. Comparisons of the abused twin with the non-abused co-twin and examination of the abuser's attitude to the victim suggested that the difference between twins in their development or in their response to parents increased the stress of child-rearing and encouraged favouritism, which resulted in abuse of only one twin. Comparison by parents of children with their siblings may be a common factor in general child abuse because it is a natural thing for parents to do. PMID:1978124

    Full Text Available Each year, millions of children around the world are the victims and witnesses of physical, sexual and emotional violence. Child maltreatment is a major global problem with a serious impact on the victims’ physical and mental health, well-being and development throughout their lives and, by extension, on society in general. Family physicians who are involved in the care of children are likely to encounter child abuse and should be able to recognize its common presentations. There is sufficient evidence that child maltreatment can be prevented. The ultimate goal is to stop child maltreatment before it starts.In this paper, the characteristics of the perpetrators and victims of child maltreatment, maltreatment types, risk factors, differential diagnosis and discuss about strategies for preventing were summarized.

    2001-04-01

    During 1999, the Idaho Department of Fish and Game (IDFG) continued developing techniques for the captive rearing of chinook salmon Oncorhynchus tshawytscha. Techniques under development included protocols for rearing juveniles in freshwater and saltwater hatchery environments, and fieldwork to collect brood year 1998 and 1999 juveniles and eggs and to investigate the ability of these fish to spawn naturally. Fish collected as juveniles were held for a short time at the Sawtooth Fish Hatchery and later transferred to the Eagle Fish Hatchery for rearing. Eyed-eggs were transferred immediately to the Eagle Fish Hatchery where they were disinfected and reared by family groups. When fish from either collection method reached approximately 60 mm, they were PIT tagged and reared separately by brood year and source stream. Sixteen different groups were in culture at IDFG facilities in 1999. Hatchery spawning activities of captive-reared chinook salmon produced eyed-eggs for outplanting in streamside incubation chambers in the West Fork Yankee Fork Salmon River (N=2,297) and the East Fork Salmon River (N=1,038). Additionally, a number of these eggs were maintained at the Eagle Fish Hatchery to ensure adequate brood year 1999 representation from these systems, and produced 279 and 87 juveniles from the West Fork Yankee Fork and East Fork Salmon River, respectively. Eyed-eggs were not collected from the West Fork Yankee Fork due to low adult escapement. Brood year 1998 juveniles were collected from the Lemhi River (N=191), West Fork Yankee Fork Salmon River (N=229), and East Fork Salmon River (N=185). Additionally, brood year 1999 eyed-eggs were collected from the Lemhi River (N=264) and East Fork Salmon River (N=143). Sixty-two and seven maturing adults were released into Bear Valley Creek (Lemhi River system) and the East Fork Salmon River, respectively, for spawning evaluation in 1999. Nine female carcasses from Bear Valley Creek were examined for egg retention, and of

    Children in foster care need more from health providers than routine well-child care. The changes in legislation that were designed to prevent children from languishing in foster care also necessitate a plan that works with the child, the biological family, and the foster family in ensuring the best outcome for the child. This approach acknowledges that most foster children will return to the biological family. Recent research on the effect of adverse childhood experiences across all socioeconomic categories points to the need for specifically designed, focused, and coordinated health and mental health services for children in foster care.

    Better health and nutrition are thought to improve children's performance in school, and therefore their productivity after school. Most literature ignores the fact that child health and schooling reflect behavioral choices, so the estimated impact of health and nutrition on a child's schooling reflects biases in the studies. Using an explicit dynamic model for preferred estimates, the authors use longitudinal data to investigate how children's health and nutrition affect school enrollment in...

  11. Sterile insect technique: a field evaluation of the quality of mass-reared fruit flies

    International Nuclear Information System (INIS)

    To optimize the use of the sterile insect technique it is essential to establish precise programmes for the evaluation of mass-reared flies in comparison with the natural population. This video presents a programme carried out at the island of Prosida which represents an extremely favourable habitat for the development of the flies; the flies are a new strain mass-reared in the IAEA's Laboratory at Seibersdorf, Austria. The technique employed is the Marked Release Recapture Technique, which consists of colouring a predetermined number of flies with fluorescent powder before they are released, and then recapturing them. This method provides valuable data about the flies' adaptability, orientation to the habitat, motility, sexual activity and reproduction

    The present study examined changes in retinal tyrosine hydroxylase (TH) expression in rats having undergone optic nerve transection and housed under a normal day/night cycle or in the dark. The aim was to investigate the effects of amacrine cells on axonal regeneration in retinal ganglion cells and on the synapses that transmit visual signals. The results revealed that retinal TH expression gradually decreased following optic nerve transection in rats housed under a normal day/night cycle, reaching a minimum at 5 days. In contrast, retinal TH expression decreased to a minimum at 1 day following optic nerve transection in dark reared rats, gradually increasing afterward and reaching a normal level at 5-7 days. The number of TH-positive synaptic particles correlated with the TH levels, indicating that dark rearing can help maintain TH expression during the synaptic degeneration stage (5-7 days after optic nerve injury) in retinal amacrine cells.

    2011-01-01

    Leaf beetles Gastrophysa viridula have attracted recently increased research interest from various points of view, since they are: (i) pest insects in rhubarb crops; (ii) potential biocontrol agents of dock plants Rumex spp. in grasslands; and (iii) a model species in ecological studies on insect population dynamics, biochemistry, behavior, biomechanics and biomimetics. The continuous rearing of beetles at standardized conditions may help to unify the fitness state of different individuals, allowing a better comparison of experimental results. The present communication suggests a modular space- and time-saving rearing method of G. viridula in stackable faunariums under laboratory conditions, which has been successfully established and continuously used over the last 5 years. Several developmental stages were kept in separate boxes, and multiple generations were kept simultaneously, depending on the required number of beetles.

    Experiments were conducted to study the life cycle of Dermestes maculatus and to establish the total developmental time and the developmental time of immature stages, in relation with six different temperatures. We also analyzed the variations in size, morphology, and other indicators of temporal variation during life cycle of D. maculatus, in relation with temperature. One hundred larvae were selected per experiment, reared individually. The remaining larvae were reared to evaluate and establish temporal variations among the instars (length, cephalic width, and dry weight). In all trials, survivorship was greater than 50% and seven larval instars were found. Data of the average developmental time of immature stages and of the total cycle, at different temperatures, are provided. This is of relevance when estimating particularly, a minimum PMI. No relation between morphometric parameters and temperature was found, suggesting that other random factors may have been involved. Thus, this indicates that the method of isomegalen diagrams could not be used for calculating PMI. PMID:26477981

    2011-01-01

    Full Text Available An active noise control scenario of simple ducts is considered. The previously suggested technique of using an single loudspeaker and its rear sound to cancel the upstream sound is further examined and compared to the bidirectional solution in order to give theoretical proof of its advantage. Firstly, a model with a new approach for taking damping effects into account is derived based on the electrical transmission line theory. By comparison with the old model, the new approach is validated, and occurring differences are discussed. Moreover, a numerical application with the consideration of damping is implemented for confirmation. The influence of the rear sound strength on the feedback-path system is investigated, and the optimal condition is determined. Finally, it is proven that the proposed source has an advantage of an extended phase lag and a time delay in the feedback-path system by both frequency-response analysis and numerical calculation of the time response.

    The effects of acute and chronic exposure to either ethylene dibromide (EDB) or mercuric chloride (MC) were studied in laboratory-reared Octopus joubini, O. maya and O. bimaculoides. The advantages of using octopuses were that the responses were immediate, highly visible and sensitive. All species demonstrated signs of toxicity to acute and chronic exposure to EDB and to MC. A dosage-sensitive relationship for the loss and subsequent recovery of locomotor response and of chromatophore expansion was found for each species after acute exposure. For each species the LC50 for chronic exposure occurred within 12 hr at 100 mg/l for EDB and within 3 hr at 1,000 mg/l for MC. This study demonstrated the potential usefulness of laboratory-reared octopuses in evaluating the toxicity of marine environmental pollutants. PMID:3072470

    The issue of whether encoding of geometric information for navigational purposes crucially depends on environmental experience or whether it is innately predisposed in the brain has been recently addressed in controlled rearing studies. Non-human animals can make use of the geometric shape of an environment for spatial reorientation and in some circumstances reliance on purely geometric information (metric properties and sense) can overcome use of local featural information. Animals reared in home cages of different geometric shapes proved to be equally capable of learning and performing navigational tasks based on geometric information. The findings suggest that effective use of geometric information for spatial reorientation does not require experience in environments with right angles and metrically distinct surfaces.
