Parental state and offspring recognition in the biparental cichlid fish Pelvicachromis pulcher

Alloparental care was investigated in the biparental West African cichlid, Pelvicachromis pulcher. Non-breeding adults typically consumed young conspecifics but this trait was inhibited in both sexes during reproductive attempts. Alien conspecific young were accepted into the brood if they were of a similar age/developmental stage to the parents' own young but not if they were much older or much younger. If not accepted they were consumed by whichever adult located them. Parents separated from their brood for up to 4 days accepted their young on reunion but separation for more than 4 days resulted in the young being consumed. This latter response occurred if chemical stimuli from the young were available during the separation but not if visual stimuli were available. In this latter case parental responsiveness was maintained. Both sexes of this externally fertilizing species appeared to have the same information about their young and showed the same changes in responsiveness and the same discriminatory abilities.

Korean Parental Beliefs About ELT From the Perspective of Teachers

In South Korea, as in many other parts of the world, children begin learning English when they are very young. Korean parents want their children to learn English as quickly as possible and often make heavy financial and other investments in their children’s English language education. English language teachers of school-age learners in Korea often feel pressure and in some cases criticism from parents regarding English language instruction. This article reports the results of a study designed to begin examining the perceptions that Korean parents hold regarding English language instruction. It illustrates how some of their beliefs reflect the latest language teaching research, whereas others are more indicative of traditional Korean belief systems, educational approaches, and methodologies.

Trophic dynamics within a hybrid zone - interactions between an abundant cyprinid hybrid and sympatric parental species

1. Recent proliferation of hybridisation in response to anthropogenic ecosystem change, coupled with increasing evidence of the importance of ancient hybridisation events in the formation of many species, has moved hybridisation to the forefront of evolutionary theory.

2. In spite of this, the mechanisms (e. g. differences in trophic ecology) by which hybrids co-exist with parental taxa are poorly understood. A unique hybrid zone exists in Irish freshwater systems, whereby hybrid offspring off two non-native cyprinid fishes often outnumber both parental species.

3. Using stable isotope and gut content analyses, we determined the trophic interactions between sympatric populations of roach (Rutilus rutilus), bream (Abramis brama) and their hybrid in lacustrine habitats.

4. The diet of all three groups displayed little variation across the study systems, and dietary overlap was observed between both parental species and hybrids. Hybrids displayed diet, niche breadth and trophic position that were intermediate between the two parental species while also exhibiting greater flexibility in diet across systems.

Understanding Parental Influence on Educational Outcomes Among 9 Year Olds in Ireland: The Mediating Role of Resources, Attitudes and Children's Own Perspectives

The relationship between parental background and children's educational outcomes has been a dominant theme within the sociology of education. There has been an on-going debate as to the relative merits of explanations which focus on the role of socio-cultural reproduction and those which focus on rational choice. However, many empirical studies within the social stratification tradition fail to allow for children's own agency in shaping the relationship between social background and schooling outcomes. This paper draws on the first wave of a large-scale longitudinal study of over 8,000 nine-year-old children in Ireland, which combines information from parents, school principals, teachers and children themselves. Both social class and parental education are found to have significant effects on reading and mathematics test scores among nine year olds. These effects are partly mediated by home-based educational resources and activities, parents' educational expectations for their child, and parents' formal involvement in the school. More importantly, children's own engagement with, and attitudes to, school significantly influence their academic performance. The influence of children's own attitudes and actions can thus reinforce or mitigate the effect of social background factors. The analysis therefore provides a bridge between the large body of research on the intergenerational transmission of inequality and the emerging research and policy literature on children's rights.

In Two Minds? Parental Attitudes toward Physical Punishment in the UK

Since the Millennium, the use of physical punishment in the home has been a widely debated topic across the UK. Reliance on public opinion has been an important feature of this debate with a variety of UK surveys showing that many find physical punishment acceptable and do not support a complete ban on smacking. Drawing on the results from a comprehensive review of the literature, this article highlights that public/parental opinion is less than straightforward. Parents are often ambivalent about physical discipline, do not view it as an optimal method of behaviour management and are more prone to smack when stressed or angry. Likewise, a survey of the disciplinary practices and attitudes of 1000 parents in Northern Ireland shows that majority of parents have negative attitudes towards physical discipline. Nonetheless, many parents continue to smack despite the fact they do not believe it to be effective. Lack of parental support for legislative reform should be reconsidered in the light of this ambivalence. Most important, the UK Government needs to reframe the smacking debate in terms of children's rights rather than relying on public opinion if it is to fulfil its commitment to protect children from harm as set out in the United Nations Convention on the Rights of the Child.

Parental Disputes, Religious Upbringing and Welfare in English Law and the ECHR

This article assesses the position of English law concerning parental disputes about the religious upbringing of children. Despite the strong emphasis on both parents being able to direct their child’s religious upbringing, courts have interpreted the child’s welfare to restrict the exposure of the child to parental religious beliefs or practices in some circumstances: preserving the child’s future choice of religion, the physical integrity of the child, the child’s contact and relationship with both parents, the child’s educational choices, and the child’s relationship with both parents’ religious community. It is suggested that courts should have a wide understanding of welfare and should be wary to prohibit parents teaching their minority beliefs. This article also compares the position of the European Court of Human Rights (ECtHR) and suggests that, despite the stronger emphasis by the ECtHR on parental rights, English law is generally not that much at odds with the ECtHR.

Parental care influences social immunity in burying beetle larvae

In this study, evidence is provided of social immunity in the offspring of a sub-social species, the burying beetle, Nicrophorus vespilloides. Nicrophorus vespilloides is a carrion breeder and, in a similar fashion to the adult beetles, the offspring produce exudates that exhibit lytic activity, which are used to coat the breeding resource. This strategy defends against the microbial community. The lytic activity in larval exudates declines as the brood develops, perhaps being most beneficial at the start of the breeding bout. Changing levels of parental care through widowing/orphaning affects lytic activity in the larval exudates, with levels decreasing in the absence of both parents.

The influence of parents, older siblings, and non-parental care on infant development at nine months of age

Background: The majority of research examining the influence of social environment on early child development suggests benefits to two-parent households, but contradictory evidence for the effects of siblings. The aims of the present study were to examine the influence of the child's proximal social environment, and the effects of interactions between socioeconomic status and social environment on developmental outcomes.

Methods: Primary caregivers of a representative sample of 10,748 nine-month-old infants in Ireland completed the Ages and Stages Questionnaire and provided information on social environment. Adjustment was made for infant and maternal characteristics, household income, and area where the child was living at the time of the study. Further analyses tested for interactions between social environment and household income.

Results: Binary logistic regressions indicated no effects for number of parents in the household. However, the presence of siblings in the household was a consistent predictor of failing to reach milestones in communication, gross motor, problem-solving, and personal-social development. Furthermore, there was a gradient of increasing likelihood of failing in gross motor, problem-solving, and personal-social development with increasing numbers of siblings. Care by a grandparent decreased the likelihood of failing in communication and personal-social development.

Conclusions:These findings do not support the majority of research that finds positive benefits for two-parent households. Similarly, the findings suggest limited effects for non-parental care. However, the observed negative effects of siblings support both the confluence and resource dilution models of sibling effect. Examination of follow-up data may elucidate current findings.

Parental leave regulations and the persistence of the male breadwinner model: Using fuzzy-set ideal type analysis to assess gender equality in an enlarged Europe

his paper uses fuzzy-set ideal type analysis to assess the conformity of European leave regulations to four theoretical ideal typical divisions of labour: male breadwinner, caregiver parity, universal breadwinner and universal caregiver. In contrast to the majority of previous studies, the focus of this analysis is on the extent to which leave regulations promote gender equality in the family and the transformation of traditional gender roles. The results of this analysis demonstrate that European countries cluster into five models that only partly coincide with countries’ geographical proximity. Second, none of the countries considered constitutes a universal caregiver model, while the male breadwinner ideal continues to provide the normative reference point for parental leave regulations in a large number of European states. Finally, we witness a growing emphasis at the national and EU levels concerning the universal breadwinner ideal, which leaves gender inequality in unpaid work unproblematized.
