    Full Text Available The aim of this study is the investigation of parents’, living in rural areas or urban areas and with children 5-6 years of age, difference in their attitudes towards children according to demographic characteristics and living conditions, rural and urban areas. The study group of the research includes 200 parents who have 5-6 years old children taking pre-school education. 100 of them live in rural areas and 100 of them live in the city center. Instruments of study are Personal Information Form and PARI (Family Life and Child-Rearing Attitude Scale. Independent samples t-test, ANOVA and Regression Analysis were used for data analysis. According to findings, mothers are more over-protective, more democratic and less disciplined than fathers. Parents living urban areas are more over-protective, more democratic and less disciplined than parents living rural areas. Moreover, parents living in extended families are more disciplined, less over-protective and less democratic egalitarian in terms of attitudes than parents live in nucleus families. As a result, educational status, gender, family type and location are predictors for parents’ child-rearing attitude. However, the variables of age and number of children do not contribute to the total variance significantly.

    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.

  11. [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

  13. Child Odors and Parenting: A Survey Examination of the Role of Odor in Child-Rearing

    Parental caregiving is critical for the survival of our young and continuation of our species. In humans, visual and auditory signals from offspring have been shown to be potent facilitators of parenting. However, whether odors emitted by our young also influence human parenting remains unclear. To explore this, we conducted a series of questionnaire surveys targeting parents with children under 6 years old. First, we collected episodes on experiencing odors/sniffing various parts of a child’s body (n = 507). The prevalence of experiencing events described in those episodes was examined in a separate survey (n = 384). Based on those results, the Child Odor in Parenting scale (COPs) was developed, and subsequently used in the main survey (n = 888). We found COPs to have adequate content validity, concurrent validity, and reliability. Responses to the COPs demonstrated that parents, especially mothers with infants, are aware of odors from their offspring, and actively seek them in daily child-rearing. The factor structure and content of the COPs items indicated that child odors have both affective and instrumental roles. Affective experiences induce loving feeling and affectionate sniffing, while instrumental experiences pertain to specific hygienic needs. The head was the most frequent source of affective experiences, and the child’s bottom of instrumental. Each was experienced by more than 90% of the mothers with a child below 1 year of age. Affective experiences significantly declined as the child grew older, possibly associated with the decline of physical proximity between parents and child. This age-related decline was not prominent for instrumental experiences, except for the bottom, which significantly declined after 3 years of age. The present findings suggest that child odors play roles in human parenting, and that their nature and significance change during the course of a child’s development. PMID:27138751

    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

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

    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. PMID:22858900

    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.

  1. Family issues in child anxiety: attachment, family functioning, parental rearing and beliefs.

    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 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.

  5. Parenthood, child-rearing and fertility in England, 1850-1914.

    Pooley, Siân

    2013-03-01

    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.

    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. Material and Method This is a survey study and research population is consisted of all male and female students of high schools and their parents in Ahvaz, out of which 384 subjects were selected by using Cochran’s formula and through multistage cluster sampling method.

Cereal based diet was the commonest complementary feeding administered by 23% of the mothers. Commonest traditional practices followed included oil massage (97.72% and use of amulets/talisman (97.72% in the study population. Conclusion: Beneficial infant feeding practices such as early initiation of breastfeeding and feeding of colustrum among rural Goan mothers was low despite accessible antenatal care and health care services. However, though some of the traditional children rearing practices followed such as oil massage, delivery at parents' home were as per the recommended norms, some of the beliefs/practices such as kajal application, bathing the newborn immediately after birth, need to be replaced by sound and scientific methods.

    Nurturing attitudes and behaviors among seven married couples, each of which contained one partner who had manic-depressive illness, and their young children were compared with those of normal control families. 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.

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.

    Full Text Available CONTEXTO: Práticas maternas são comportamentos específicos, por meio dos quais as mães/cuidadores desempenham suas tarefas maternais. Estas práticas poderiam influenciar o desenvolvimento motor de lactentes. OBJETIVO: verificar a influência de práticas maternas, utilizadas no cuidado diário de lactentes saudáveis, sobre seu desenvolvimento motor do 6º ao 12º meses de vida. MÉTODO: Selecionados 14 lactentes, nascidos a termo e saudáveis, avaliados longitudinalmente no 6º, 9º e 12º meses de vida, utilizando-se a Alberta Infant Motor Scale. Em cada avaliação/idade a mãe respondeu a um questionário fechado sobre práticas, predominantemente adotadas no cuidado diário do lactente durante os períodos de vigília. Considerou-se neste estudo a postura predominantemente adotada pelo lactente, local preferencial de permanência e a forma de carregar o lactente no colo. RESULTADOS: No 9º mês de vida o desempenho motor dos lactentes foi influenciado positivamente pela predominância na postura de quatro apoios, em relação à sentada e prono ou supino e pela permanência no chão em relação ao carrinho de bebê. No 12º mês houve influência positiva da predominância na postura de quatro apoios e em pé. A postura predominante no 6º mês de vida e a forma de carregar o lactente no 6º, 9º e 12º meses de vida não influenciaram o desempenho motor do grupo estudado. CONCLUSÃO: Os resultados sugerem que as práticas que estimulam a adoção da postura de quatro apoios e a utilização do chão como local de permanência influenciam positivamente o desenvolvimento motor de lactentes saudáveis a partir do 6º mês de vida.BACKGROUND: Child-rearing practices are defined as specific behavioral patterns used during maternal duties.

    This thesis describes the effects of different rearing strategies for young rabbit does on body development and reproduction performance. In current rearing, does are often fed to appetite from weaning to first insemination. First insemination is applied when 75 to 80% of mature body weight (BW) is reached, that occurs around 14 to 16 weeks of age. Under current rearing, young does loose significant part of their fat and energy reserves during first lactation. This seems related to the decrea...

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

    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. PMID:6916808

    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

    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

  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.

  7. 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

  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

  11. Recent developments in medfly mass rearing

    International Nuclear Information System (INIS)

    Continuous light in the adult stage increased by 15-20% the number of eggs produced by artificially reared Mediterranean fruit flies as compared with a 14:10 h light:dark regime. This increase was not apparent when the flies were kept in high density mass rearing cages because of a steep increase in insect mortality owing to the continuous light. An oviposition net, with hole size similar in diameter to the female's ovipositor, almost doubled the number of eggs produced per female as compared with oviposition nets with large holes. The increased degree of egg 'sticking' observed on the net with small holes was reduced significantly when the net was treated with a lubricant release agent. In a 'starter-finisher' standard IAEA Seibersdorf Laboratory larval diet, sugar could be replaced in the finisher diet with molasses. In an all-molasses diet, the quantity of molasses could be reduced by 50% in the finisher diet without any substantial effect on insect production or quality. The spent finisher larval diet, heat treated to kill the remaining larvae or pupae, could be used for successful second larval production, provided it was mixed again with water and small amounts of sugar and combined with a fresh starter diet. Collection of all larvae within the first 'popping' day by a 'tumbling' machine, and subsequent pupation in wheat bran, resulted in the smallest pupae, but longest living adults, as compared with four day popping and pupation in wheat bran, sand, talc and 'naked' pupation. The latter resulted in a significant decrease in adult survival. Pupal handling procedures for sterile insect technique release reduced both adult emergence and flight ability. The percentage of emergence was substantially reduced by mechanical sorting, irradiation, storage at low temperature and packing in airtight plastic bags, while flight ability was affected substantially by fluorescent powder treatment for adult marking and, to a lesser extent, by irradiation and low temperature

  12. INTERGENERATIONAL EDUCATIONAL ATTAINMENT, FAMILY CHARACTERISTICS AND CHILD OBESITY.

    Jones, Antwan

    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

    A hot-cell facility was constructed at the IMEF building for the demonstrate ACP process. ACP hot-cell consists of process cell and maintenance cell, and each cell has rear door. Since this facility was constructed at basement floor, all process materials, equipment and radioactive materials are take in and out through the rear door. Also, this door can be an access route of workers for the maintenance works. Therefore ACP hot-cell rear doors must maintain the radiation shielding, sealing, mechanical and structural safety. This report presents design criteria, design contents of each part and driving part. It was confirmed that the rear doors sufficiently maintain the safety through the structural analysis and shielding analysis. Also, it was confirmed that the rear doors were constructed as designed by the gamma scanning test after the installation.

    A range of rear surface structures have been developed and studied for the purpose of improving the performance of buried contact solar cells (BCSC). In particular, improved results are reported for the double grooved BCSC with oxidized p-type rear surface, with V{sub oc} of 685 mV having been demonstrated. The importance of including an alneal treatment is clearly evident with open circuit voltages typically degrading 60 mV without its inclusion. Devices with the same structure but with a rear floating junction are also evaluated within the study and again the dependence on an alneal is evident for cells with low surface phosphorus concentration. In the highest voltage devices, the rear boron diffused grooves contribute almost 30% of the total device dark saturation current, with test devices achieving V{sub oc} as high as 694 mV for a BCSC with the rear grooves replaced by photolithographically defined boron diffused contact regions.

  16. Behavioral and hormonal effects of attachment object separation in surrogate-peer-reared and mother-reared infant rhesus monkeys.

    Meyer, J S; Novak, M A; Bowman, R E; Harlow, H F

    1975-09-01

    Mother-reared and surrogate-peer-reared rhesus monkeys were separated from their respective attachment objects at 6 months of age and tested for the following 9 weeks to determine their home-cage behavior and their pituitary-adrenocortical responses to stress. Both groups displayed a strong immediate behavioral response to separation which was characterized by increased vocalization, increased locomotion, and decreased self-play. However, the surrogate-peer-reared infants showed a subsequent recovery in their levels of self-play whereas the mother-reared infants instead developed stereotypic behavior patterns such as repetitive pacing. The 2 groups displayed similar plasma cortisol responses to weekly sessions in an apparatus equipped with animated toy "monsters". Mother-reared but not surrogate-peer-reared subjects, however, also manifested elevated cortisol levels when an animal in an adjacent cage was captured and removed for stress testing. Mother-reared infant monkeys thus responded in a stronger and more prolonged manner to the loss of their attachment object than surrogate-peer-reared infants. These results suggest that infant rhesus monkeys form stronger attachments to monkey mothers than to inanimate surrogate mothers, a phenomenon which has not been as clearly demonstrated using other indices of attachment strength.

    1994-05-01

    In, 1993, two successful fish-rearing pilot projects were conducted in Hanford Site 100 K Area water treatment pools (K Pools) that are excess to the US Department of Energy needs. Beginning this spring, two larger cooperative fish programs will be undertaken in the K Pools. One program will involve the Yakama Indian Nation, which will rear, acclimate, and release 500,000 fall chinook salmon. The other program involves the Washington Department of Fish and Wildlife, which will rear warm-water specie (walleye and channel catfish) for planting in state lakes. Renewed economic vitality is the goal expected from these and follow-on fish programs.

    There is a vast literature describing the importance of child rearing aspects as vulnerability factors predisposing to depression, anxiety and alcohol use in adulthood. Much of the research in the field uses a variety of methods and theoretical bases, making conclusions difficult to draw.

  2. Welfare aspects in rabbit rearing and transport

    Directory of Open Access Journals (Sweden)

    Claudio Cavani

    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.

    2009-05-01

    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.

  4. Maternal beliefs as long-term predictors of mother-child interaction and report.

    Science.gov (United States)

    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. PMID:2083506

  10. Rearing Temperature Influences Adult Response to Changes in Mating Status.

    Westerman, Erica; Monteiro, Antónia

    2016-01-01

    Rearing environment can have an impact on adult behavior, but it is less clear how rearing environment influences adult behavior plasticity. Here we explore the effect of rearing temperature on adult mating behavior plasticity in the butterfly Bicyclus anynana, a species that has evolved two seasonal forms in response to seasonal changes in temperature. These seasonal forms differ in both morphology and behavior. Females are the choosy sex in cohorts reared at warm temperatures (WS butterflies), and males are the choosy sex in cohorts reared at cooler temperatures (DS butterflies). Rearing temperature also influences mating benefits and costs. In DS butterflies, mated females live longer than virgin females, and mated males live shorter than virgin males. No such benefits or costs to mating are present in WS butterflies. Given that choosiness and mating costs are rearing temperature dependent in B. anynana, we hypothesized that temperature may also impact male and female incentives to remate in the event that benefits and costs of second matings are similar to those of first matings. We first examined whether lifespan was affected by number of matings. We found that two matings did not significantly increase lifespan for either WS or DS butterflies relative to single matings. However, both sexes of WS but not DS butterflies experienced decreased longevity when mated to a non-virgin relative to a virgin. We next observed pairs of WS and DS butterflies and documented changes in mating behavior in response to changes in the mating status of their partner. WS but not DS butterflies changed their mating behavior in response to the mating status of their partner. These results suggest that rearing temperature influences adult mating behavior plasticity in B. anynana. This developmentally controlled behavioral plasticity may be adaptive, as lifespan depends on the partner's mating status in one seasonal form, but not in the other. PMID:26863319

  13. 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.)

    Injuries from road traffic accidents are set to become the second highest cause of disability-adjusted life years lost in developing countries by 2020. The number of injuries and deaths are disproportionately high in low income countries, which account for only 40% of all motor vehicles. Human behaviour is thought to be a major factor in most accidents. In Oman wearing a seat belt is compulsory in the front seats but not in the rear. Wearing a seat belt can reduce the severity of injuries when sitting in rear seats. This study examines the use of seat belts in cars entering a university and hospital campus in Oman to determine the degree of seat belt wearing in the rear. At peak times on a selected day, cars were stopped at the university's entrance barrier. The type of driver was identified - student, employee, hospital patient or visitor - and the degree of seat belt wearing among driver and passengers was noted. A total of 1,066 cars were stopped. Of this total, 90.1% of drivers and 80.9% of front seat passengers were wearing a restraint complying with Local traffic regulations. However, only 1.4% of back seat passengers wore a seat belt. Only 3.7% of children under the age of five were restrained in a child seat and only 16.7% of five- to 12-year-olds were strapped in. A third (34.6%) of under-fives were sitting in the front seat. In cars with child occupants, 40% of the time parents wore seat belts but the children did not. Occupants conformed to the law but behaviour indicated a lack of awareness of the dangers of not wearing seat belts, especially towards children. Traffic regulations need to be updated and the public educated about the need to wear seat belts. Health agencies could be more active in educating the public about road safety behaviour and should also be involved in the overall strategy to reduce injuries and deaths. PMID:15602998

  19. Child Care Gifts to Bolster Astronomy

    Science.gov (United States)

    Nemiroff, Robert J.; Allen, Alice

    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.

    The present study aimed to explore the prevalence and frequency of child psychological maltreatment and its correlated factors in Chinese families. A cross-sectional investigation was conducted among 1,002 parents of primary school students in Yuncheng City, China. Data were collected using the self-report questionnaire anonymously. Results showed that 696 (69.5%) surveyed parents had different extents of psychological maltreatment toward their children in the past 3 months. The high prevalence of parental psychology maltreatment was significantly associated with high scores on parental over-reactivity and low scores on recognition of child psychology maltreatment. These findings indicate that it is urgent to develop cultural interventions to raise parents' awareness of preventing child psychological maltreatment and to help parents use nonviolent child rearing in China.

    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. In this article, it was aimed to discuss psychosocial factors related to the development of OCD symptoms, by examining a case in detail, who had childhood traumatic experiences and has been raised in an environment where negative parenting styles exist, and who physically abused her own child.

    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.

    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 implications of child care subsidies for child development. In this paper, we provide a systematic assessment of the impact of subsidy receipt on a wide ran...

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

    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.

    In side collision accidents, the head is the most frequently injured body region for child occupants seated in a child restraint system (CRS). Accident analyses show that a child's head can move out of the CRS shell, make hard contact with the vehicle interior, and thus sustain serious injuries. In order to improve child head protection in side collisions, it is necessary to understand the injury mechanism of a child in the CRS whose head makes contact with the vehicle interior. In this research, an SUV-to-car oblique side crash test was conducted to reconstruct such head contacts. A Q3s child dummy was seated in a CRS in the rear seat of the target car. The Q3s child dummy's head moved out beyond the CRS side wing, moved laterally, and made contact with the side window glass and the doorsill. It was demonstrated that the hard head contact, which produced a high HIC value, could occur in side collisions. A series of sled tests was carried out to reproduce the dummy kinematic behavior observed in the SUV-to-car crash test, and the sled test conditions such as sled angle, ECE seat slant angle and velocity-time history that duplicated the kinematic behavior were determined. A parametric study also was conducted with the sled tests; and it was found that the impact angle, harness slack, chest clip, and the CRS side wing shape affected the torso motion and head contact with the vehicle interior.

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

    Science.gov (United States)

    Ng, Choy Peng; Law, Teik Hua; Wong, Shaw Voon; Kulanthayan, S

    2013-01-01

    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

    2004-01-01

    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.

    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.

    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.

  9. 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. PMID:26468514

    2013-12-01

    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

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.

Despite a series of policy initiatives, recent reports suggest that the child poverty rate may now be comparable to that in 1989. The apparent persistence of child poverty in Canada might reflect socioeconomic developments, or something about the way that child poverty is measured. Using micro data covering the period 1986 to 2000 we find little support for these explanations.

    Driver distraction represents a well-documented and growing contribution to the road safety problem. This study used a naturalistic, observational approach to examine if children in vehicles are a significant source of driving distraction. Families with children aged between 1 and 8 years drove an instrumented "study vehicle" on their regular trips for 3 weeks. A discrete video recording system in the vehicle provided images of the driver and front seat passenger, the rear seat child passengers and the traffic ahead. The video-recordings inside and outside the vehicle were analysed to identify potential distracting activities, where 'distraction' was broadly defined as any activity that distracted the driver or competed for their attention while driving. In addition, all potentially distracting activities that involved the driver looking away from the forward roadway for more than 2s while the vehicle was in motion were also coded. Video-recordings were analysed for 92 driving journeys undertaken by 12 families including 25 children and 19 drivers. The mean journey duration was approximately 16 min (range: 2 min-3h 34 min). Most journeys were undertaken during the day (89%), with the mother driving (65%) and without a front seat passenger (64%). Driving journeys were predominantly undertaken in urban areas (97%), on suburban roads/streets (94%), and under low complexity traffic conditions (91%). Most journeys involved some source of potential driver distraction (98%), with drivers distracted for 18% of the driving journey. The most frequent types of distracting activities that drivers engaged in included: touching their head or their face (35%), interacting with child passengers in the rear seat (12%), and engaging with the front seat passenger (9%). Almost three-quarters of these potentially distracting activities were engaged in by the driver while the study vehicle was in motion (72%) and 14% of all potentially distracting activities involved the driver's eyes

  9. Quality evaluation of the mass reared Asian corn borer, Ostrinia furnacalis Guenee

    International Nuclear Information System (INIS)

    W.D. Guthrie et al. reported that the European corn borer (ECB), Ostrinia nubilalis Huebner, mass reared continuously on a meridic diet for over 14 generations, will eventually lose its virulence to susceptible inbred lines of maize. However, the present paper indicates that this is not the case with the Asian corn borer (ACB), Ostrinia furnacalis Guenee, when mass reared on a semi-artificial diet developed by the first author. Larvae reared continuously for as many as 26 generations still maintain their ability to cause serious whorl and stalk damage to susceptible maize materials. It cannot be concluded, however, that the diet and rearing technique for ACB are superior to those for ECB unless the two diets are used to rear the two Ostrinia species at the same time and under the same rearing conditions.

    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.

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.

  15. Genetic versus rearing-environment effects on phenotype: hatchery and natural rearing effects on hatchery- and wild-born coho salmon.

    Directory of Open Access Journals (Sweden)

    Cedar M Chittenden

    Full Text Available With the current trends in climate and fisheries, well-designed mitigative strategies for conserving fish stocks may become increasingly necessary. The poor post-release survival of hatchery-reared Pacific salmon indicates that salmon enhancement programs require assessment. The objective of this study was to determine the relative roles that genotype and rearing environment play in the phenotypic expression of young salmon, including their survival, growth, physiology, swimming endurance, predator avoidance and migratory behaviour. Wild- and hatchery-born coho salmon adults (Oncorhynchus kisutch returning to the Chehalis River in British Columbia, Canada, were crossed to create pure hatchery, pure wild, and hybrid offspring. A proportion of the progeny from each cross was reared in a traditional hatchery environment, whereas the remaining fry were reared naturally in a contained side channel. The resulting phenotypic differences between replicates, between rearing environments, and between cross types were compared. While there were few phenotypic differences noted between genetic groups reared in the same habitat, rearing environment played a significant role in smolt size, survival, swimming endurance, predator avoidance and migratory behaviour. The lack of any observed genetic differences between wild- and hatchery-born salmon may be due to the long-term mixing of these genotypes from hatchery introgression into wild populations, or conversely, due to strong selection in nature--capable of maintaining highly fit genotypes whether or not fish have experienced part of their life history under cultured conditions.

    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 diversity of both wild and reared Pseudosciaena crocea (Richardson) col-lected from Guan-Jing-Yang in Ningde, China in May 1999 was investigated by random amplified poly-morphic DNA (RAPD) in the present study. The polymorphism and mean difference of the wild popula-tion as revealed by RAPD were 18.9% and 0.0960 respectively, and those of the reared stocks were rel-atively lower, with 16.7% in polymorphism and 0.0747 in mean difference. 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.

    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.

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

    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

    2010-01-01

    This article has its roots in the basic contradictions, which go back to the eighteenth and nineteenth centuries, between the self-interest and the care of others, exemplified by the delegation of responsibility for the care of children and other vulnerable persons. 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

    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

    Most embryological studies of lampreys in the Great Lakes have been conducted with filtered water from Lake Huron. Although this water was entirely satisfactory for the earlier work, the present need for knowledge of the effects of various compounds on embryological development requires that the initial medium be sterile. The purpose of the present study was to determine whether sea lamprey embryos could be successfully reared in distilled water. Mature sea lampreys were collected from the Ocqueoc River, Presque Isle County, Michigan, and transferred to the Hammond Bay Biological Station where eggs were stripped and fertilized according to the method of Piavis. After activation was ascertained to be 90-100% complete, the embryos were washed 3-5 timesexperimentals with commercially obtained U.S.P. distilled water and controls with filtered Lake Huron water.

    This paper surveys many aspects and issues of child labor, including its causes and effects as well as policies associated with it. Child labor has come to be considered an expression of poverty, both a cause and an effect of underdevelopment. Child labor cannot be viewed in isolation from educational, health, fertility, and technological issues; and is not necessarily an aberration but a rational household response to an adverse economic environment. With this in mind, the following proposit...

    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

    In order to meet government supervision of pork production safety as well as consumeŕs right to know what they buy, this study adopts animal identification, mobile PDA reader, GPRS and other information technologies, and put forward a data collection method to set up rearing files of pig in smallhold pig farming, and designs related metadata structures and its mobile database, and develops a mobile PDA embedded system to collect individual information of pig and uploading into the remote central database, and finally realizes mobile links to the a specific website. The embedded PDA can identify both a special pig bar ear tag appointed by the Ministry of Agricultural and a general data matrix bar ear tag designed by this study by mobile reader, and can record all kinds of inputs data including bacterins, feed additives, animal drugs and even some forbidden medicines and submitted them to the center database through GPRS. At the same time, the remote center database can be maintained by mobile PDA and GPRS, and finally reached pork tracking from its origin to consumption and its tracing through turn-over direction. This study has suggested a feasible technology solution how to set up network pig electronic rearing files involved smallhold pig farming based on farmer and the solution is proved practical through its application in the Tianjińs pork quality traceability system construction. Although some individual techniques have some adverse effects on the system running such as GPRS transmitting speed now, these will be resolved with the development of communication technology. The full implementation of the solution around China will supply technical supports in guaranteeing the quality and safety of pork production supervision and meet consumer demand.

    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.

    We build a model of child labor and study its implications for welfare. We assume that there is a trade-off between child labor and the accumulation of human capital. Even if parents are altruistic and child labor is socially inefficient, it may arise in equilibrium because parents fail to fully internalize its negative effects. This occurs when bequests are zero or when capital markets are imperfect. We also study the effects of a simple ban on child labor and derive conditions under which i...

  8. What defines successful integration into a social group for hand-reared chimpanzee infants?

    Bashaw, Meredith J; Gullott, Rebecca L; Gill, Emily C

    2010-04-01

    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.

    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).

    2016-03-01

    Full Text Available Purpose. To analyze the results of rearing and provide aquaculture-biological characteristic of peled reared in polyculture with sturgeons and cyprinids based on pond technology. Methodology. The material for the studies were fry, young-of-the-year, yearlings and age-1+ peled produced from eggs exported in March 2009 from Russian Federation. Rearing of peled was carried out based on the technology developed by the All-Union Scientific and Research Institute of Pond Fish Culture for coregonids with the use of methodical recommendations on the biotechnology of industrial rearing of seed coregonids. Studies were carried out at the pond fish farm “Korop” of Lviv region. Water supply of rearing ponds was done by self-flow. The investigation of fish diet and hydrobiological studies were carried out using conventional methods. Findings. We performed a study of fish egg incubation and produced larvae with their further rearing in floating cages to the fingerling stage. Rearing of peled in polyculture allows increasing the fish productivity parameters at the first year of rearing by 1.3%, at the second year by 0.9%. Average weights of age-1 and age-1+ peled were 185.3 g and 450 g, respectively. In these rearing conditions, daily growth of the young-of-the-year was within 0.1-1.5 g, age-1+ – 1.1-3.3 g. As a positive result of rearing, we should note high weight gain during winter period that was more than 50%. We also investigated qualitative and quantitative composition of zooplankton and peled juvenile diet. Originality. The works of peled rearing based on pond technology in polyculture with sturgeons and cyprinids were carried out in the conditions of Ukraine for the first time. Practical value. The results of the performed works along with similar previous works on peled rearing in ponds will be used for the creation of methodical recommendations on rearing of peled seeds, which will be used by Ukrainian fish farms in future.

    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.

  12. 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.)

  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.

    2016-04-01

    In salmonids, the release of hatchery-reared fish has been shown to cause irreversible genetic impacts on wild populations. However, although responsible practices for producing and releasing genetically diverse, hatchery-reared juveniles have been published widely, they are rarely implemented. Here, we investigated genetic differences between wild and early-generation hatchery-reared populations of the purple sea urchin Paracentrotus lividus (a commercially important species in Europe) to assess whether hatcheries were able to maintain natural levels of genetic diversity. To test the hypothesis that hatchery rearing would cause bottleneck effects (that is, a substantial reduction in genetic diversity and differentiation from wild populations), we compared the levels and patterns of genetic variation between two hatcheries and four nearby wild populations, using samples from both Spain and Ireland. We found that hatchery-reared populations were less diverse and had diverged significantly from the wild populations, with a very small effective population size and a high degree of relatedness between individuals. These results raise a number of concerns about the genetic impacts of their release into wild populations, particularly when such a degree of differentiation can occur in a single generation of hatchery rearing. Consequently, we suggest that caution should be taken when using hatchery-reared individuals to augment fisheries, even for marine species with high dispersal capacity, and we provide some recommendations to improve hatchery rearing and release practices. Our results further highlight the need to consider the genetic risks of releasing hatchery-reared juveniles into the wild during the establishment of restocking, stock enhancement and sea ranching programs.

    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.

    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

    Full Text Available Child abuse is harm to, or neglect of, a child by another person, whether adult or child. Child abuse happens in all cultural, ethnic, and income groups. Child abuse can be physical, emotional - verbal, sexual or through neglect. Abuse may cause serious injury to the child and may even result in death. A problem that is only beginning to come into light in India rape, sexual abuse, and sexual harassment are worldwide issues of gender violence. There is very little research done in this area in India and only a few books have been written, keeping the subject even further from the consciousness of the country. However, the problem persists with staggering incidence, and Indians unique profile adds to the complexity of an already difficult subject. Fortunately, the issue of child sexual abuse is slowly becoming a more recognized issue, and for this reason, this paper will focus much on sexual abuse against minor children: the laws, victims, and perpetrators. Finally, an analysis of the aspects of Indian culture that make this issue particularly difficult to understand and cope with will be presented.

    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 birds were housed in individual cages in a environmentally controlled room(T=18÷20°C; 16L:8D and fed ad libitum standard breeder diet. A sample of thirty eggs was analysed for each phase of thelaying period (beginning, peak and end. The following chemico-physical parameters: egg, albumen, yolk and shell weight;yolk colour; egg and shell dry matter (DM; shell thickness (blunt end, pointed end and middle part were measured. Theprotein, lipid, and cholesterol content was evaluated; the fatty acid (FA profile analysed. We observed: egg weight averageof 34.5g ; a high proportion of yolk (37% in the whole egg (Y/E, consequently, a high lipid content of 13.9%; a protein contentDM of 44.3%; the fatty acid composition was similar to that of chicken egg and the oleic acid (36.4% was the majorproportion of the total fatty acids, as in the domestic fowl. The rearing pheasant’s egg has a high nutritive concentration, dueto high ratio yolk/whole egg, with biological and nutritional characteristics similar to domestic fowl’s egg.

    The effect of the addition of zeolite to pig feed ration was studied in the cage rearing system under production conditions. Zeolite was mixed in the COS I and COS II feed mixtures directly in the feed plant, the mixing ratio being 100 kg feed mixture + 5 kg zeolite. The feed mixture was administered in granular form ad libitum. The test group had 648 weanlings and the control group 674 weanlings; the piglets, kept in two-story cages in four sections, were arranged so that the test group could be a mirror-like reflection of the control group. The trial lasted 45 days. The piglets given the fortified feed ration had daily weight gains higher by 0.017 kg and feed consumption lower by 0.234 kg per 1 kg of gain, as compared with the control animals. The costs of the feed ration required for producing a kilogram of gain were 8.55 Cz. crowns in the zeolite group and 9.422 crowns in the control group. PMID:6312666

    Full Text Available The present work aimed at determining the tolerance of Nile tilapia juveniles to highly acidic rearing waters and the effects of water acidity on the quality of tank effluents. The experimental design consisted of four treatments with different water pH values (4.12 ± 0.84; 5.13 ± 0.74; 6.14 ± 0.64 and 8.06 ± 0.48, with five replicates each. No exchange of water was performed throughout the study, only water replenishment to maintain the initial level. Variables of water quality, soil, growth performance, metabolism and effluents were monitored for eight weeks. Despite the lower total ammonia nitrogen (TAN concentration in the pH 8 tanks, their levels of non-ionized ammonia (NH3 were the highest ones. At the end, the lowest body weight of fish was observed in the pH 8 tanks. There was a significant improvement in feed conversion ratio (FCR and protein efficiency ratio (PER due to to water acidification. There were reduced concentrations of NH3 in the acidified tanks’ effluents. It was concluded that the gradual water acidification up to pH 4 can improve the Nile tilapia juveniles’ growth performance.

    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 pecentage 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.

    Inkjet printing of photoresist material may provide a new route for low-cost fabrication of patterned oxide passivation layer of solar cells that require fine patterning and simple process. However, printing by liquid-based, environmentally friendly ink and printing device required development efforts aimed at achieving a fine patterning and long used inkjet nozzles under corrosive influence. This work was demonstrated a concept for grooved silicon oxide patterning for rear localized contact of p-n junction solar cells by chemical etching after photoresist patterning obtained. This article reviews the silicon dioxide fabrication on p-Si substrate from sol-gel technique for oxide passivation layer of solar cells. The aluminium was deposited on the patterned oxide layer and then heated at its Al-Si eutectic temperature. Finally, an aluminium-induced solid-phase epitaxial growth of p+ forming into the openings of the oxide passivation layer was presented. The sheet resistance of n-emitter layer, carrier life-time and surface recombination velocity values are investigated. Photoconductive measurements were performed on the prepared samples after each thermal process to measure the effective lifetime of the minority carriers. Carrier lifetime up to 60 microseconds has been measured on c-Si wafer passivated by the opened SiO2 layer. It was shown that the patterned SiO2 passivation has obtained high passivation quality making by the proposed inkjet printing method.

  12. The influence of rearing order on personality development within two adoption cohorts.

    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. PMID:10934690

    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.

    The aim of this study was to determine serological values of lysozyme, hemolytic complement levels (alternative pathway), and bactericidal activity of serum in turkeys kept in different rearing systems (industrial, backyard, and experimental). Results showed that the values for serum bactericidal activity and hemolytic complement levels increased with age, and their values were higher in experimental and in industrial turkeys than in turkeys reared in backyard. Lysozyme concentration showed a similar pattern; its value was higher in the industrial and experimental groups than in the backyard group. Data obtained suggest that rearing system can have an influence on the natural immune parameters considered; experimental and industrial groups showed a similar trend, differentiated from that observed in the backyard group. In the backyard group, the values observed may suggest that hybrid turkeys, selected for high production, have difficulty with being reared outside where predators (foxes and weasels) and weather conditions could be responsible for a stress situation.

    Full Text Available This ethological study was  carried out to establish the occurrence of psychosis in dogs, reared both in-home (as a pet and in dog kennels. The dogs housed in kennels were reared either individually (as working animals or in groups (in kennels. All the pet dogs were reared alone in the households. The highest occurrence of psychotic states was encountered in stray dogs housed in kennels and followed by the pet dogs. These states were very rarely observed in individually reared dogs at farms and working dogs. The possible explanation is that they were submitted to less stressors due to good management at farms and the proper approach on the basis of their temperaments, i.e. their welfare was at the highest level.

    As part of ongoing ecological studies and reproduction enhancement efforts for macaws in southwestern Peru, a health survey of parent- and hand-reared scarlet macaws (Ara macao) and blue and gold macaws (Ara ararauna) was conducted in 1994. Thirty-three birds were examined during handling procedures, and blood samples were collected from 27 (9 parent reared, 18 hand reared) for laboratory analysis. All but one bird appeared to be in good condition, with no abnormality noted during physical examination. Hematology, plasma chemistries, and plasma vitamin and mineral levels were studied and correlated with the results of bacterial and viral serology. Positive antibody titers for Salmonella and psittacine herpesvirus were found. These diseases have the potential to affect wildlife population dynamics, and Salmonella may have public health significance. Serological tests for avian influenza, infectious laryngotracheitis, paramyxovirus-1, -2, -3, polyoma virus, chlamydiosis, and aspergillosis were negative. Differences in disease prevalence were found between rearing situations. PMID:9523629

    2002-04-01

    To determine if the defences of sockeye salmon (Oncorhynchus nerka) raised in captivity are affected by the rearing temperature or their life-cycle stage, various indices of the humoral and cellular immune functions were measured in fish reared at either 8 or 12 degrees C for their entire life-cycle. Measures of humoral immunity included the commonly used haematological parameters, as well as measurements of complement, and lysozyme activity. Cellular assays quantified the ability of macrophages from the anterior kidney to phagocytise Staphylococcus aureus cells, or the activities of certain bactericidal systems of those cells. The T-dependent antibody response to a recombinant 57 kDa protein of Renibacterium salmoninarum was used to quantify the specific immune response. Fish were sampled during the spring and fall of their second, third and fourth years, corresponding to a period that began just before smolting and ended at sexual maturation. Fish reared at 8 degrees C tended to have a greater percentage of phagocytic kidney macrophages during the first 2 years of sampling than the fish reared at 12 degrees C. During the last half of the study the complement activity of the fish reared at 8 degrees C was greater than that of the 12 degrees C fish. Conversely, a greater proportion of the blood leucocytes were lymphocytes in fish reared at 12 degrees C compared to the fish reared at 8 degrees C. Fish reared at 12 degrees C also produced a greater antibody response than those reared at 8 degrees C. Results suggested that the immune apparatus of sockeye salmon reared at 8 degrees C relied more heavily on the non-specific immune response, while the specific immune response was used to a greater extent when the fish were reared at 12 degrees C. Although a seasonal effect was not detected in any of the indices measured, varying effects were observed in some measurements during sexual maturation of fish in both temperature groups. At that time there were dramatic

  20. 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.

    Early life adversity is associated with a broad scope of life-long health and behavioral disorders. Particularly critical is the role of the mother. A possible mechanism is that these effects are mediated by “epigenetic” mechanisms. Studies in rodents suggest a causal relationship between early life adversity and changes in DNA methylation in several “candidate genes” in the brain. This study examines whether randomized differential rearing (maternal versus surrogate-peer rearing) of rhesus m...

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.

  10. The investigation on the stratification phenomenon of aluminum rear alloyed layer in silicon solar cells

    International Nuclear Information System (INIS)

    Highlights: • A stratification phenomenon of Al rear alloyed layer in solar cells is found. • The stratification phenomenon is related to the formula of the paste. • From the analyses, the stratification phenomenon is redundant and deleterious. • The highest cell's efficiency without stratification phenomenon is close to 20%. - Abstract: A stratification phenomenon of aluminum rear alloyed layer was found in the study of aluminum rear emitter N-type solar cells. It is related to the composition of the paste. The outer aluminum alloyed layer can be called as aluminum doped emitter, and it gives the contribution to the junction formation. The inner layer is only the Al/Si mixed layer. The aluminum atoms in this layer are not bonded with silicon atoms. This inner layer will ruin the quality of the rear junction. The shunt resistance, reverse current density and the junction electric leakage value are getting worse when the thickness of the inner layer increases. The thickness of the inner Al/Si mixed layer increases with the increasing of firing temperature, while the depth of the aluminum doped emitter almost does not change. From the analyses, the inner Al/Si mixed layer is redundant and deleterious. Only a single deep aluminum doped rear emitter is needed for N-type solar cells. The highest power conversion efficiency of 19.93% for aluminum rear emitter N-type cells without the stratification phenomenon has been obtained

    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 The effects of sublethal pesticide exposure on queen emergence and virus titers were examined. Queen rearing colonies were fed pollen with chlorpyrifos (CPF alone (pollen-1 and with CPF and the fungicide Pristine® (pollen-2. Fewer queens emerged when larvae from open foraging (i.e., outside colonies were reared in colonies fed pollen-1 or 2 compared with when those larvae were reared in outside colonies. Larvae grafted from and reared in colonies fed pollen-2 had lower rates of queen emergence than pollen-1 or outside colonies. Deformed wing virus (DWV and black queen cell virus were found in nurse bees from colonies fed pollen-1 or 2 and in outside colonies. The viruses also were detected in queen larvae. However, we did not detect virus in emerged queens grafted from and reared in outside colonies. In contrast, DWV was found in all emerged queens grafted from colonies fed pollen-1 or 2 either reared in outside hives or those fed pollen-1 or 2. The results suggest that sublethal exposure of CPF alone but especially when Pristine® is added reduces queen emergence possibly due to compromised immunity in developing queens.

    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.

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.

    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

    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

  1. Investigations into the causes and methods of reducing airflow induced buffeting over vehicle rear windows

    Science.gov (United States)

    Deaton, Larry

    Rear Window Buffeting (RWB) is the low-frequency, high amplitude, helicopter-type sound that results in many 4-door vehicles when driven 30-70 mph with one rear window lowered. This event is a cause for concern among the occupants of an affected vehicle, and may result in great discomfort to the occupants if actions are not taken to reduce the magnitude of the event. In this dissertation, a comparison is made between moon roof buffeting and rear window buffeting, and data are presented where Sound Pressure Levels approaching 130 dB have been measured. This level may actually be causing ear pain in some people. Various explanations are presented in the literature for the root causes of rear window buffeting. This dissertation presents the results of an investigation to determine the root cause of rear window buffeting in a compact Sport Utility Vehicle. A brief synopsis of the types of flow-induced noises is provided, and three types of wind noises are described. Comparison between the classic spring-mass-damper system is made to the Helmholtz resonator, and the application of the Helmholtz resonator system to a vehicle cabin is discussed. A comprehensive explanation is provided to explain the mechanism resulting in the closely related moon roof buffeting problem. The presence of frequency lock-on is discussed, and data are provided demonstrating lock-on. Data are presented showing how rear window buffeting also exhibits lock-on, and three regions of differing air flow patterns along the side of the test vehicle are described. Data are presented supporting the three region concept and how the various attachments and geometries of the vehicle interact that make some vehicles more susceptible to the rear window buffeting problem. A comparison between the relative magnitudes of Moon Roof Buffeting and Rear Window Buffeting is made and an explanation is provided. Previously published computational fluid dynamics (CFD) work advocating that the root cause of rear window

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

    Science.gov (United States)

    Hesse, Saskia; Thünken, Timo

    2014-04-01

    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.

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

    Science.gov (United States)

    Janczak, Andrew M; Riber, Anja B

    2015-07-01

    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

    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.

    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

    Full Text Available Postembryonic rearing of carp larvae in closed recirculatory system was conducted in 2009 at the fish farm Ribnjak LLC, Donji Miholjac, Croatia. The research was conducted in two test groups (A and B with three iterations in each with a control group (C. Test group A (3 tanks x 250 l consisted of 150 000 larvae (density of 200 larvae•l-1, test group B (3 tanks x 500 l consisted of 600 000 larvae (density of 400 larvae•l-1, and the control group (C was a mud fish pond T-6 which was stocked by 800 000 larvae•ha-1 under standard production conditions. In this research, basic physical and chemical water parameters were controlled (temperature, oxygen, pH, total ammonia and nitrites. Initial measuring of carp larvae total length (TL was conducted prior to their placement into tanks (N=120. On the fourth, sixth, eighth and tenth day of research 20 larvae (N=140 were taken out of every tank as well as out of control group and measured. Feeding with live feed began on the third day after hatching (larval TL 6.00±0.36 mm. Ten minutes after feeding live feed to larvae for the first time, 20 larvae (N=120 were taken out of every tank and a high portion of larvae that accepted live feed (89.17±3.76% was determined by a magnifying glass. Feeding artificial feed began on the seventh day after the hatching. After ten minutes, a high portion of larvae who accepted artificial feed (96.67±2.58% was determined. Since the end of the research, the determined length increment (ITL per day was 0.41±0.04 mm, a very high survival rate was established (group A: 96%, group B: 93%. Feeding frequency was four times a day in five-hour intervals (at 06:00, 11:00,16:00 and 21:00 hours. The research was terminated after ten feeding days due to deteriorating condition of zoohygienic filter. The total of 3807 g of live feed and 1080 g of artificial feed was used.

    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.

    2014-05-01

    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.

    General practitioners and pediatricians are on the front line to detect atypical developmental trajectories in children, They have to inform parents and to guide them toward specialized centers where further multidisciplinary evaluation will be conducted. It is admitted that early intervention is a factor of better prognosis in autism. To help starting early intervention, general practitioners may first indicate sensorymotor or language and communication evaluations. A specific project will then be defined for each child according to the results of the multidisciplinary evaluation. Each individualized project will be based on different behavioral and developpemental interventions, speech therapy, sensorymotor therapy, and psychotherapy. General practitioners and pediatricians will keep up following the child evolution as part of the child care team with parents and specialized centers. PMID:20402134

    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.

  3. 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.

    Full Text Available Productive performance and egg characteristics of Ancona laying hens reared under three different rearing systems (conventional, organic and organic-plus were compared during an experimental period of one year. Three-hundred-sixty Ancona female chicks at 28 days of age were divided in three groups and assigned to different rearing systems. The organic group had 4m2 pasture/hen according to the requirements imposed by the EC Regulation 1804/99, whereas the organic-plus group had a larger grass paddock (10m2/hen. The Control group was reared in cages under standard housing conditions. The following egg characteristics were recorded and analysed during the year-long cycle: egg weight and egg mass laid/d, weight of egg components, shell thickness, Haugh index and yolk colour. Egg quality was affected by the pasture available. The hens that ingested grass (organic-plus, produced eggs with higher shell weight and percentage, darker yolk colour and higher α-tocopherol, carotenoid and polyphenol contents. The other egg traits were not affected by rearing system.

    2002-04-01

    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 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.

  6. 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)

    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

  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.

    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.

    2001-09-13

    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.

  11. The contribution of genetics and early rearing experiences to hierarchical personality dimensions in chimpanzees (Pan troglodytes).

    2015-11-01

    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.

  12. Is child work necessary?

    OpenAIRE

    Bhalotra, Sonia

    2000-01-01

    This paper investigates whether the income from child wage work is necessary to the survival of rural households in Pakistan. It is by no means obvious that it is. For instance, children may work because the returns to work exceed the returns to school, or because parents are selfish or short-sighted. It is argued here that, if child work is necessary, then the income effect of a wage change will dominate the substitution effect and the labour supply curve will be "forward falling" or negativ...

  11. 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)

    2006-01-01

    Pyemotidae mites have been reported as ectoparasites of a large number of arthropods, especially of insects. These mites are frequently found attacking insects in different habitats, including insect rearing. This paper reports the occurrence of Pyemotes sp., ventricosus group, in colonies of Tuta absoluta (Meyerick) (Lepidoptera: Gelechiidae), Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) and Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae), in the insect rearing laboratory of ESALQ-USP, in Piracicaba, State of São Paulo, provoking dematitis in those involved with the rearing. This is the first report of a Pyemotes species parasitizing T. absoluta and S. zeamais. Considering the capacity of Pyemotes to cause dermatitis in human beings, demonstrated by other authors, the direct use of the Pyemotes species found in this work for the control of the reported insect species may not be promising.

    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.

    2003-01-01

    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.

    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 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.

Internet is a perfect environment for children, for exploring the world, learning and having fun. However, access to illegal sites that contain violence and sexuality, and contact dangerous people are among the particular risks for children using the internet. It is a known fact that, internet and developing technology make the production and distribution of child pornography cheaper and easier. There has been consensus on the need of creating a plan and increasing the awareness in the community for the fight against child pornography. Because of the increasing internet use and the risk for children mentioned, nurses got new responsibilities. Nurses have to inform society, especially families and children, about safe internet use. In this review, legal regulations about the fight against child pornography on the internet, the reasons that lay the ground for child pornography and their negative effects on children has been addressed.

  10. 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)

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

    Science.gov (United States)

    Baer, L. A.; Chowdhury, J. H.; Wade, C. E.; Ronca, A. E.; Dalton, Bonnie (Technical Monitor)

    2002-01-01

    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.

  12. Incorporation of diapause into codling moth mass rearing: Production advantages and insect quality issues

    International Nuclear Information System (INIS)

    The codling moth (CM), Cydia pomonella L. (Lepidoptera: Tortricidae) is a widely distributed species and the key pest of apples and pears in orchards of the Pacific Northwest. CM possesses facultative diapause and the mature 5th instar larva is the overwintering stage (Brown 1991). British Columbia, Canada, is attempting to eradicate CM using the sterile insect technique (SIT). The Okanagan-Kootenay Sterile Insect Release (SIR) Program began releasing sterile CM in 1994 (Dyck et al. 1993, Bloem and Bloem 1996) and results in recent years have been excellent. Despite the fact that standard rearing operations have gone extremely well, and weekly CM production has increased from 8.7 million CM per week in 1994 to 14.2 million per week in 1997, the ability to mass rear diapausing CM holds a number of advantages that are currently not available. The ability to stockpile CM larvae in diapause throughout the fall and winter months when the mass rearing facility is underutilised would: 1) provide additional CM for release during the spring/summer field season, 2) provide back-up material to guard against colony losses due to operational failures and/or pathogen outbreaks, 3) allow for a potentially more cost-effective use of the facility by maintaining production year round, 4) facilitate the development of mass rearing techniques for key parasitoids that attack the overwintering stage, 5) allow for the easy shipment (and sale) of CM to researchers around the world. Here we outline the current standard CM mass rearing procedures and discuss research that has allowed diapausing CM to be mass reared (Bloem et al. 1997). We also discuss research that suggests diapaused CM are more competitive than standard non-diapaused CM (Bloem et al. 1998)

Goat rearing annually produce about 177.6 millions tons of milk (FAO, 1992) and about 3.5 millions tons of meat (FAO, 1996), with an increasing request of product, that in the last decade has driven the increase of the number of heads reared (Knights et al., 1997)...

    We examine the key factors that influence a firm's decision whether to use front-loaded or rear-loaded incentives. When using price packs, direct mail coupons, FSI coupons or peel-off coupons, consumers obtain an immediate benefit upon purchase or a front-loaded incentive. However, when buying products with in-pack coupons or products affiliated with loyalty programs, promotion incentives are obtained on the next purchase occasion or later, i.e., a rear-loaded incentive. Our analysis shows th...

  19. Aeroelastic tailoring using lamination parameters: drag reduction of a Formula One rear wing

    OpenAIRE

    Thuwis, G. A. A.; De Breuker, R.; Abdalla, M.M.; Gürdal, Z.

    2009-01-01

    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. A fibre reinforced composite torsion box ...

    Rpe65 knockout mice (Rpe65-/-) are unable to synthesize the visual pigment chromophore 11-cis retinal; however, if these animals are reared in complete darkness, the rod photoreceptors accumulate a small amount of 9-cis retinal and its corresponding visual pigment isorhodopsin. Suction-electrode recording of single rods from dark-reared Rpe65-/- mice showed that the rods were about 400 times less sensitive than wild-type control rods and that the maximum responses were much smaller in amplitude. Spectral sensitivity measurements indicated that Rpe65-/- rod responses were generated by isorhodopsin rather than rhodopsin. Sensitivity and pigment concentration were compared in the same mice by measuring light responses from rods of one eye and pigment concentration from the retina of the other eye. Retinas had 11-35% of the normal pigment level, but the rods were of the order of 20-30 times less sensitive than could be accounted for by the loss in quantum catch. This extra desensitization must be caused by opsin-dependent activation of the visual cascade, which leads to a state equivalent to light adaptation in the dark-adapted rod. By comparing the sensitivity of dark-reared Rpe65-/- rods to that produced in normal rods by background light, we estimate that Rpe65-/- opsin is of the order of 2.5x10(-5) as efficient in activating transduction as photoactivated rhodopsin (Rh*) in WT mice. Dark-reared Rpe65-/- rods are less desensitized than rods from cyclic light-reared Rpe65-/- mice, have about 50% more photocurrent and degenerate at a slower rate. Retinas sectioned after 9 months in darkness show a larger number of photoreceptor nuclei in dark-reared animals than in cyclic light-reared animals, though both have fewer nuclei than in cyclic light-reared wild-type retinas. Both also have shorter outer segments and a lower free-Ca2+ concentration. These experiments provide the first quantitative measurement of opsin activation in physiologically responding mammalian rods

    1983-08-01

    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

    Children have rights, as enumerated in the Declaration of the Rights of the Child, and need protection from violence, exploitation, and abuse. Global threats to child safety exist. These threats include lack of basic needs (food, clean water, sanitation), maltreatment, abandonment, child labor, child marriage, female genital mutilation, child trafficking, disasters, and armed conflicts/wars. Recent disasters and armed conflicts have led to a record number of displaced people especially children and their families. Strategies and specific programs can be developed and implemented for eliminating threats to the safety of children. PMID:26613687

    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.

  11. CHILD LABOR DISGRACE

    Institute of Scientific and Technical Information of China (English)

    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.

  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

    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.

The research was conducted at 25 ± 1ºC, RH 60 ± 10% and photophase of 14 hours. Six artificial diets were compared: a whole wheat flour (48.5%, ground rice (48.5% and sugar (3%; b ground rice (97% and sugar (3%; c whole wheat flour (48.5%, rice flour (48.5% an sugar (3%; d whole wheat flour (97% and yeast (3%; e wheat germ (97% and yeast (3%; f rice bran (94%, sugar (3% and yeast (3%; f rice bran (94%, sugar (3% and yeast (3%. All of the diets studied permitted the development of C. cephalonica although the diets with wheat germ and yeast and that consisting of rice bran, sugar and yeast proved to be the most adequate for rearing the moth. These diets reduced the total (egg-adult cycle, shortened the egg laying period, and produced heavier adults. Studies on the fertility life tables showed that higher net reproduction rates (Ro and finite ratio of increase (lambda were obtained from adults reared on these diets.

    Frost, Deborah; McAuley, W.; Maynard, Desmond

    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.

  7. Development of a Natural Rearing System to Improve Supplemental Fish Quality, 1991-1995 Progress Report.

    Energy Technology Data Exchange (ETDEWEB)

    Maynard, Desmond J.; Flagg, Thomas A.; Mahnken, Conrad V.W.

    1996-08-01

    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.

    Julio Marcos Melges Walder

    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.

  11. 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)

    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.

    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.

    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. 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. PMID:26328769

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.

  2. Demographic and quality control parameters of Anastrepha Fraterculus (Diptera: Tephritidae) maintained under artificial rearing

    International Nuclear Information System (INIS)

    The integration of the sterile insect technique (SIT) in the management of the South American fruit fly Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) is a promising alternative to chemically-based control in those areas where it is sympatric with Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) or other tephritid species for which the SIT is being used. Implementation of the SIT requires the development of a cost effective mass-rearing protocol. In this work, we present demographic and quality control parameters for the A. fraterculus strain reared at the Estacion Experimental Agroindustrial Obispo Colombres, Tucuman, Argentina. Considering the rearing cage as the reproduction unit, we observed that fecundity is optimal during the first 3 weeks after the onset of oviposition. Fertility was constant during this period. During 2003 and 2004, some improvements were made to the existing rearing protocol, which resulted in increased larval viability, pupal weight, and adult emergence. Current weekly egg production is 1 million per week. These eggs are used to maintain the colony and to assess quality parameters. Finally, research needs leading to improved yields and fly quality are discussed. (author)

  3. Injury risk for rear-seated occupants in small overlap crashes.

    2013-01-01

    Small overlap crashes, where the primary crash engagement is outboard from the longitudinal energy absorbing structures of the vehicle, have received recent interest as a crash dynamic that results in high likelihood of injury. Previous analyses of good performing vehicles showed that 24% of crashes with AIS 3+ injuries to front seat occupants were small overlap crashes. However, similar evaluations have not been conducted for those rear seated. Vehicle dynamics suggest that rear seat occupants may be at greater risk due to lack of lateral seating support and a steering wheel to hold, making them more sensitive to lateral movement seen in these crashes. Thus, the objective was to calculate injury risk for rear-seated occupants in small overlap collisions. AIS 2+ and AIS 3+ injury risk was calculated from NASS-CDS data from 2000-2011. Inclusion criteria were vehicles of model year 2000 or later, with CDC codes of "FL" or "FR", and an occupant in the second or third row. AIS2+ injury risk was 5.1%, and AIS3+ injury risk was 2.4%. Of note, half of the occupants were Occupants seated near side were nearly three times as likely to sustain an AIS2+ injury than occupants seated far side. Particular attention should be paid to the prominence of head injuries in this crash dynamic and consideration given to their mitigation. Additional research should determine whether countermeasures being implemented for front seat occupants can be beneficial to rear seat occupants. PMID:24406964

    Child marriages have been practiced in India for thousands of years. Even though its popularity has now decreased due to changes in law and society, it is still a major problem, causing a great deal of hardship. Even though laws prohibited child marriage as early as 1860, statistics show that, on the average, Indians marry very young (1972: females at age 17; males at age 22 years of age; 34 females and 13 males under age 15). The following are incentives to marry young and have large families: 1) religion teaches that only those with descendants go to heaven; 2) unmarried women are traditionally scorned; and 3) most importantly, economic reasons encourage people to have large families as soon as possible, e.g., male children are encouraged to marry to obtain the dowry as soon as possible and children are considered a source of income in India. Child marriage in India causes the following problems: 1) a high infant mortality rate, as much as 75% in rural areas; 2) an imbalance in the male to female ratio (1901: 970 females/1000 males; 1971: 930 females/1000 males) because women who marry young tend to lose their health earlier; 3) a population explosion: in 1971, the Indian population was found to be increasing at the rate of 225/1000.

    Full Text Available Child labour is conventionally defined to include all ‘economically active’ children in the age group 5-14 years. A person is treated as economically active or gainfully employed if she does work on a regular basis and receives remuneration for it. The ILO defied child labor as “work that deprives children of their childhood and their dignity, which hampers their access to education and the acquisition if skills, and which is performed under deplorable conditions harmful to their health and their development.” Child work, on the other hand, includes all paid and unpaid work for the household or for the market whether it is full time or part time. Participation in household activities on a regular basis and for several hours in a day to relieve adults for wage employment is also included in this definition. The ILO argues tat it sis not concerned with children helping in family farms or doing household chores.

    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

    This article discusses the state of social change and the disparity between India's Constitutional aims and actual practice in addressing gender inequality and the special risks of female children in India. The second part of this article summarizes Constitutional articles and laws relating to protection of women and a girl child. Before birth, a female child is at risk of fetal death. A woman is at risk of poorly performed abortions and maternal mortality. After birth, a girl child is at risk of child care of younger siblings, housework, lack of education, wage work for the household, sexual abuse, vulnerability at work or school or on the street, murder by her parents, abuse, malnutrition, and desertion. The SAARC summit declared 1990 the Year of the Girl Child. UN conventions and a world summit focused on the Rights of the Child. A child has a right to freedom from exploitation, neglect and abuse, and access to food, health care, and education. Articles 14, 15, and 16 of India's Constitution guarantee protection from discrimination on grounds of religion, race, caste, sex, or place of birth and equality of opportunity in public employment. Article 23 prohibits trafficking in humans and forced labor. Article 24 prohibits child labor under the age of 14 years. Article 39 assures an adequate means of livelihood, equal pay, and protection from child abuse and economic pressure to work in jobs unsuitable to a child's age and strength. Article 45 provides for free and compulsory education up to 14 years of age. Article 51 prohibits derogatory practices against women. Article 325 and 326 prohibits sex discrimination. Other laws pertain to dowry, marriage age, prostitution, abortion, juvenile justice, kidnapping, obscenity, procurement of a minor, sexual offenses, divorce and child support, child care, maternity benefits, and cruelty by a husband or relatives. The girl child in India continues to live in perpetual threat, both physiological and psychological. PMID

    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.

    Phorid flies have been considered viable options for biological control of leaf-cutter ants because they are highly specific to these hosts, producing direct mortality and also affecting the normal functioning of colonies. Designing protocols for mass rearing of these insects requires knowing the temperature and humidity conditions that optimize their development in terms of duration, survivorship and longevity of adults. We reared Apocephalus setitarsus Brown, Eibesfeldtphora trilobata Disney, and Myrmosicarius brandaoi Disney, which are specific leaf-cutter ant parasitoids of Atta vollenweideri Forel, and Apocephalus neivai Borgmeier and Myrmosicarius catharinensis Borgmeier, which are parasitoids of Acromyrmex lundii Guérin-Méneville. Phorids were maintained under one of five different rearing conditions, 20°C high humidity (20HH), 24°C low and high humidity (24LH and 24HH), and 28°C low and high humidity (28LH and 28HH). Flies from all species could complete their development under all the conditions tested. As expected, the 20HH treatment significantly lengthened all developmental periods in all species, whereas the shortest duration was achieved under 28HH. Although pupal survivorship was highest at 24HH, the greatest longevity of adults was achieved at 20HH. Percentage of pupae obtained and pupal survivorship also exhibited the highest values at 24HH. The rearing efficiency index was highest for all species at 24HH. Therefore, we suggest this temperature and humidity combination as the most suitable for rearing these species, whereas the 20HH treatment is ideal for maintaining adults for longer periods, which would be advantageous for synchronizing matings and mass releases of adults in the field.

  13. 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

    In this paper, we show how coordination failures may explain the prevalence of child labor in developing countries. We do so within a simple game-theoretic setup. Child labor arises in our environment because of the lack of a coordination mechanism between parental decisions to invest in the human capital of their children and firm's decisions to invest in skill-intensive technology. Governmental policies that help coordinate expectations lead to the disappearance of child labor.

  6. The Supply of Child Labour

    OpenAIRE

    2004-01-01

    The paper develops a theoretical framework, and a diagrammatic apparatus, for explaining the supply of child labour. It examines the effect of credit, insurance, and poverty (defined as more than just low income). It also explains bonded child labour, a modern form of slavery closely associated with the worst forms of child exploitation. The analysis is positive, but provides some of the elements for a normative judgement.

    It is often forgotten that child labor is part of a multi-generational problem due in part to the failure to educate girls. Although the literacy rate for women has improved over the last two decades, in many countries it is less than half that of their male counterparts. This in turn leads to nutritional deficiencies, poverty, and poor health. While many researchers address the immediate health effects of child labor on the child laborers, this article addresses the issue of child labor from...

  10. Communication and community development: early child development programs.

    Wood, F; Reinhold, A J

    1993-01-01

    Community-based groups are organized around particular aspects of early childhood development (ECD), such as literacy, parent education, and early childhood activities. In the Colombian national program, community households call upon women to devote a portion of their home to organized child care for minimal material reward. The Indian Child Development Service subsidizes the payment of organizers; and Kenyan parents construct basic preschool facilities, provide school lunches, and subsidize a teacher. In such cases the government plays a subordinate role, while the burden of program maintenance is carried by the community. These programs share the characteristics that children and adults learn side by side; adult learning ranges from women's literacy, to health, organizational issues, or small-scale economic development; a strong cultural component emphasizes mother tongue language learning, indigenous child-rearing practices, and local working models; physical structures are in homes; capacity-building for the adults is central which will be transferred to other spheres of community life. In the remote coastal villages of Colombia, an organization called Promesa works with mothers on designing their preschool children's educational activities. Promesa began to confront other priority needs in the villages, especially in environmental health and malaria control. A 1990 assessment related that participants' pride, self-confidence, and ability to solve problems regarding the healthy development of their children increased; groups learned to make use of the physical, human, and institutional resources from their environments; and participants' children remained in school and performed better. Conclusions from a decade of loose experimentation suggest that through communication community women can be organized to provide basic early education and early childhood activities can help rural children over the cultural barrier of school.

  11. 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.

  12. Curbing child marriages.

    Science.gov (United States)

    Rajan, S I

    Demographers are interested in marriage age because women who marry early are exposed to conceptions through the most fecund years of their lives. Women who marry young are exposed comparatively to a longer duration and tend to shorten the intergenerational years, consequently influencing the fertility to be higher. In India, despite the law, child marriages occur in many states, more prevalent among the backward conservative communities. According to India's Child Marriage Restraint Act, a woman must be 18 to marry (a man 21), but in fact in 1981 the marriage age of females was 15. This young marriage age is substantiated by available survey and report data. For example, in a mass marriage solemnized at Wardha village in Vidisha district in 1981, there was not 1 of the 110 couples of the prescribed marriage age. 55 of the brides were below age 10 and 48 were between 10-12 years. Only 8 brides were older than 14 years. A survey conducted by the Population Research Center, Lucknow University, revealed that more than half of the females surveyed were married before age 15. The census data for 1981 provide the following information: 1.19 million or 2.63% of the total 45.18 million boys aged 10-14 years and 2.67 million or 6.59% of the total 40.49 million girls were married. Christians had the highest mean age at marriage followed by Sikhs and Jains, but all religious groups had shown an improvement in their age at marriage. Several factors are responsible for child marriage. Consequently, a multidimensional approach to dealing with the problem is needed. The way to bring about this change is through creating more job and educational opportunities for women. PMID:12280896

    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

    Recent studies have revealed that parents in different cultures endorse different child-rearing practices. Studies in the West suggest that there is a cluster of behavioral characteristics in children that are linked with each type of parenting styles. Mixed results, however, were found in non-Western countries. This study examined (1) parenting practices in Canadian and Chinese mothers, and (2) the relevance between parenting practices and child behaviors in Canada and China. Forty Canadian children (average age = 5.40) and 39 Chinese children (average age = 4.84) and their mothers participated in the study. Information on maternal authoritative and authoritarian behaviors and children's behaviors, including coercive request, polite request, and assertiveness, was obtained from observations of mother-child interactions in a laboratory situation. The results indicated that Chinese mothers were less authoritative and more authoritarian than Canadian mothers. Both cross-cultural differences and similarities were found on the associations between maternal parenting practices and child behaviors. PMID:20132462

  9. Early rearing interacts with temperament and housing to influence the risk for motor stereotypy in rhesus monkeys (Macaca mulatta).

    Vandeleest, Jessica J; McCowan, Brenda; Capitanio, John P

    2011-06-01

    Laboratory and zoo housed non-human primates sometimes exhibit abnormal behaviors that are thought to reflect reduced wellbeing. Previous research attempted to identify risk factors to aid in the prevention and treatment of these behaviors, and focused on demographic (e.g. sex or age) and experience-related (e.g. single housing or nursery rearing) factors. However, not all animals that display abnormal behavior possess these risk factors and some individuals that possess a risk factor do not show behavioral abnormalities. We hypothesized that other aspects of early experience and individual characteristics might identify animals that were more likely to display one specific abnormal behavior, motor stereotypy (MS). Using logistic regression we explored the influence of early rearing (involving four different types of rearing conditions), and variation in temperament, on likelihood of displaying MS while controlling for previously identified risk factors. Analyses indicated that having a greater proportion of life lived indoors, a greater proportion of life-indoors singly-housed, and a greater number of anesthesias and blood draws significantly increased the risk of displaying MS (P < 0.001). Rearing condition failed to independently predict the display of MS; however significant interactions indicated that single housing had a greater impact on risk for indoor-reared animals versus outdoor-reared animals, and for indoor mother-reared animals versus nursery-reared animals. There were no main effects of temperament, although interactions with rearing were evident: scoring high on Gentle or Nervous was a risk factor for indoor-reared animals but not outdoor-reared animals. The final model accounted for approximately 69.3 % of the variance in the display of MS, and correctly classified 90.6% of animals. These results indicate that previously identified risk factors may impact animals differently depending on the individual's early rearing condition. These results are
