AbstractProtein-based materials are considered versatile biomaterials, and their biodegradability is an advantage for sustainable development. Bagworm produces strong silk for use in unique situations throughout its life stages. Rigorous molecular analyses of Eumeta variegata suggested that the particular mechanical properties of its silk are due to the coexistence of poly-A and GA motifs. However, little molecular information on closely related species is available, and it is not understood how these properties were acquired evolutionarily or whether the motif combination is a conserved trait in other bagworms. Here, we performed a transcriptome analysis of two other bagworm species (Canephora pungelerii and Bambalina sp.) belonging to the family Psychidae to elucidate the relationship between the fibroin gene and silk properties. The obtained transcriptome assemblies and tensile tests indicated that the motif combination and silk properties were conserved among the bagworms. Furthermore, our analysis showed that C. pungelerii produces extraordinarily strong silk (breaking strength of 1.4 GPa) and indicated that the cause may be the C. pungelerii -specific balance of crystalline/amorphous regions in the H-fibroin repetitive domain. This particular H-fibroin architecture may have been evolutionarily acquired to produce strong thread to maintain bag stability during the relatively long development period of Canephora species relative to other bagworms.

Active Child

The quality and stability of sibling relationships during adulthood were assessed by comparing TAT themes of sibling affiliation, conflict, and separation at the period of active child-rearing (CR) and the empty nest (EN). Thirty men and thirty women, divided equally between the two life stages, were randomly selected from a pool of individuals who had a same-sex, closely-spaced sibling. The Sibling Thematic Apperception Test (S-TAT) was developed to elicit underlying feelings about the relationship, because traditional methods of assessment have failed to tap its negative qualities. Contrary to previous findings, results showed no differences in affiliation or conflict theme frequencies between the CR and EN periods. Separation themes, however, were more frequent during the CR than the EN period, suggesting that concerns over separation from siblings reflect a developmental process which might be related to bonding with the family of procreation. Although there were no sex differences within life periods, women's stories about sisters across life period had more conflict themes than did men's stories about brothers.

Model Family

According to the intergenerational solidarity model, family members who share similar values about family obligations should have a closer relationship and support each other more than families with a lower value consensus. The present study first describes similarities and differences between two family generations (mothers and daughters) with respect to their adherence to family values and, second, examines patterns of relations between intergenerational consensus on family values, affectual solidarity, and functional solidarity in a sample of 51 mother-daughter dyads comprising N = 102 participants from Luxembourgish and Portuguese immigrant families living in the Grand Duchy of Luxembourg. Results showed a small generation gap in values of hierarchical gender roles, but an acculturation gap was found in Portuguese mother-daughter dyads regarding obligations toward the family. A higher mother-daughter value consensus was related to higher affectual solidarity of daughters toward their mothers but not vice versa. Whereas affection and value consensus both predicted support provided by daughters to their mothers, affection mediated the relationship between consensual solidarity and received maternal support. With regard to mothers, only affection predicted provided support for daughters, whereas mothers’ perception of received support from their daughters was predicted by value consensus and, in the case of Luxembourgish mothers, by affection toward daughters.

Csr Engagement

The objective of this paper is to find the relationship between family firms’ CSR engagement and their non-family member employees’ organisational identification. Drawing upon the existing literature on social identity theory, corporate social responsibility and family firms, the author proposes that family firms engage actively in CSR programs in a balanced manner to increase non-family member employees’ organisational identification. The findings of the research suggest that by developing and implementing balanced CSR programs, and actively getting engaged in CSR activities, family firms may help their non-family member employees better identify themselves with the firms. The article points out that due to unbalanced CSR resource allocation, family firms face the problem of inefficient CSR program implementation, and are suggested to switch alternatively to an improved scheme. Family firms may be advised to take corresponding steps to select right employees, communicate better with non-family member employees, use resources better and handle firms’ succession problems efficiently. The paper extends employees’ identification and CSR research into the family firm research domain and points out some drawbacks in family firms’ CSR resource allocation while formerly were seldom noticed.

Children, brought up in foster families, experience various problems (diffi culties in interpersonal relationships with parents, diffi culties in communicating with peers, emotional instability), which lead to confl icts, quarrels, running away from home, destructive phenomena, etc. One of the eff ective forms of working with children brought up in foster families is individual counselling. Individual counselling is used by various specialists (psychologists, educators, psychotherapists), where a special place is taken by a social educator. His or her activity involves the implementation of social-protective, preventive, educational, informational, advisory functions. In the process of organizing individual counseling, the social educator takes into account the social situation of the family and the child, personal characteristics, social conditions, social and cultural characteristics and the nature of the relationship with the social environment. To organize individual counseling, a social educator needs to master various and eff ective techniques, and take into account a number of recommendations. An analysis of the literature and practical socio-pedagogical experience led to an understanding of the insuffi cient degree of elaboration of this issue. The purpose of this article was the solution to this problem.

Undeserving Poor

This chapter examines the sociocognitive dimensions of cultural categorizations of deservingness. The social issue of poverty has been a persistent source of debate in the American system of policy development, influenced by conceptual distinctions between the “haves” and “have-nots,” “working moms” and “unemployed dads,” and the “deserving poor” and the “undeserving poor.” Although there is a wealth of literature discussing the ideological underpinnings of stratification systems, these discussions often focus on categorical distinctions between the poor and the nonpoor, with much less discussion of distinctions made among the poor. Moreover, while scholars of culture and policy have long referenced the importance of cultural categories of worthiness in policy development, the theoretical significance of these distinctions has been largely understudied. I expand the discourse on the relationship between cultural representations of worth and social welfare policy by exploring how these categories are conceptualized. Drawing on analytical tools from a sociology of perception framework, I create a model that examines deservingness along continuums of morality and eligibility to highlight the taken-for-granted cultural subtleties that shape perceptions of the poor. I focus on social filters created by norms of poverty, welfare, and the family to explore how the deserving are differentiated from the undeserving.

Abstract Anxiety and depression are one of the most distressing symptoms for the family caregivers. Little is known about the relationship between sleep impairments and anxiety/depression in this population and how objective and subjective sleep measures differ in relation to anxiety. This study was designed to examine the relationship between sleep impairments and anxiety/depression in people with dementia, using both subjective and objective sleep measures. Among the 170 study participants, 50% (n=85) reported to have anxiety/depression. In univariate logistic regression analyses on anxiety/depression, adjusting for dementia stage, people with more subjective sleep impairment had higher odds of having anxiety/depression (OR=1.111; 95% CI: 1.020-1.211, p=0.016) and people with poorer subjective sleep quality had higher odds of having anxiety/depression (OR=1.702; 95% CI: 1.046-2.769, p=0.032). Objective sleep measures from actigraphy did not show any significant relationships to anxiety/depression. The results suggest that subjective sleep measures are closely related to anxiety/depression in this population.
