This study investigated factors affecting the adjustment of parentally bereaved children by reviewing existing literature and comparing it to observations made by professional social workers. Interviewees had between 1 1/2 and 22 years of experience in counseling bereaved children. The specific factors examined were age and sex of the bereaved child, circumstances of the death, and adjustment of remaining caregiver. Participants (n = 5) responded to an interview instrument specifically designed for this study which contained seven in-depth, open-ended questions. Participants’ replies were mostly in accordance with the literature, but also generated some new perspectives that had not been previously considered for this study and had not appeared in the literature. This study has implications for practice with parentally bereaved children and their surviving caregivers.Rebecca M.

This article investigates and compares the dominant concepts of public policy concerning the employment-parenthood interface in the UK and Austria. These two countries have been chosen because they represent very different public policy conceptions, particularly in approaching the work-family issue. In order to show the consequences of these policies the paper focuses on working time and time away from employment, when children are very young, and relates these aspects to currently introduced and changed regulatory structures, such as working time regulations and statutory parental leave. The active labour market and family policy in Austria, generally, supports the reconciliation of employment and parenthood. However, the Austrian work-family 'system' suffers from the underlying notion of the male breadwinner model in public support structures and low normative support of employed mothers. The cultural barriers for a more equal distribution of the burdens of combining employment and parenthood seem to be lower in the UK. The market as the political focus, in general, allows more equal opportunities for (qualified) women in the labour market and within families. But the highly flexible and polarised labour market, passive public policy and weak legal protection of employed parents creates a difficult relationship between paid work and family life for many parents, in particular for low-skilled, low-paid parents, above all mothers. These analyses provide the basis for conclusions for public policy aiming at the reconciliation of paid work and parenthood. Ce texte cherche à comparer les concepts dominants de la politique gouvernementale concernant l'interface travail-parent en Grande-Bretagne et en Autriche. Ces deux pays ont été choisis parce qu'ils présentent des concepts de politique gouvernementale très différents, en particulier en ce qui concerne la question de la famille et le travail. Ce texte montre les conséquences de la pratique de ces politiques sur le temps au travail rémunéréet le temps passé à l'extérieur de l'emploi ou sans emploi, et ce, dans un contexte o[ugrave] les enfants sont jeunes. Le texte fait la relation entre ces éléments et la pratique des structures de contrôle existantes et modifiées telles que les lois (ou: les règlements) sur le temps passéau travail et sur les congé parentaux. En général, le marché du travail et la politique de la famille en Autriche encourage la conciliation entre l'emploi et la responsabilité de parent. Par contre, ce système de travail- famille autrichien est un concept qui est fondé à la fois sur le modèle de l'homme comme fournisseur principal du revenu familial dans les structures de soutien public ainsi que sur normes de soutien peu élevées pour les mères employées. Les barrières culturelles face àune distribution plus égalitaire de la responsabilité travail-famille semblent être moins élevées en Grande-Bretagne. En général, le marché et la politique du marché du travail ont offerts plus d'opportunités aux femmes qualifiées. Mais la volatilité (et la polarisation) du marché du travail, la politique gouvernementale passive et la faible protection légale pour les parentstravailleurs créent tous une relation difficile pour les parents entre le travail rémunéré et la vie de famille--en particulier pour ceux qui sont moins qualifiés et mal rémunérés, dont surtout les mères de famille. Cette analyse nous guide vers la nécessité d'une politique gouvernementale qui vise la conciliation entre le travail rémunéré et la responsabilité parentale. 相似文献

Clinical implications and ethical dilemmas of the use of confidential case material in clinical writing are examined, including
a review of the discourse among professionals who publish clinical work. This literature is applied to a clinical illustration
of psychotherapy with a client who gave consent for publication and read the clinical write-up of her case material. It is
suggested that clinical writing may increase client “self-reflection” if there is a “secure base” of attachment between therapist/author
and the client. The impact on the client’s treatment process is examined, in addition to a discussion of ethical questions
and professional recommendations.

Siblings who have suffered severe trauma and disrupted attachment relate to one another in ways that interfere with individual development, the chance to benefit from connections with adults, the establishment of healthy sibling relationships, and the working through of traumatic experiences. The authors use case examples to illustrate four distinct sibling patterns: absent, adult lockout, half and half, and trauma shield. The authors highlight the importance of recognizing these types and then varying the therapist's treatment stance to pursue five goals. These include suspending problematic sibling relationships to create room for bonding with caring adults, transferring attachment behaviors and impulses to a receptive adult, resuming healthy individual development, forming more adaptive sibling connections, and expressing shared traumatic content. 相似文献

Having demonstrated its credentials as one of the more elegant and robust conceptualisations of human relationships, attachment theory has considerable relevance to social work. Attachment‐based research has flourished over the past few years and it now includes an impressive array of studies across the lifespan. This article considers four different measures used in attachment‐based research, although more discussion is devoted to interview and projective measures because they specifically embrace a psychodynamic approach in their design and analytic focus. The aim of the article is to provide a brief overview of each measure and to offer some illustrative examples using practice‐related material. 相似文献

Effortful Control Mediates Relations Between Children's Attachment Security and their Regard for Rules of Conduct 下载免费PDF全文
J. K. Nordling Lea J. Boldt Jessica O'Bleness Grazyna Kochanska 《Social Development》2016,25(2):268-284
Although attachment security has been associated with children's rule‐compatible conduct, the mechanism through which attachment influences early regard for rules is not well established. We hypothesized that effortful control would mediate the link between security and indicators of children's emerging regard for rules (discomfort following rule violations, internalization of parents’ and experimenter's rules, few externalizing behaviors). In a longitudinal study, the Attachment Q‐Set was completed by parents, effortful control was observed, and Regard for Rules was observed and rated by parents. The proposed model fit the data well: Children's security to mothers predicted their effortful control, which in turn had a direct link to a greater Regard for Rules. Children's security with fathers did not predict effortful control. The mother‐child relationship appears particularly important for positive developmental cascades of self‐regulation and socialization. 相似文献

Social capital has been considered a cause and consequence of various uses of new information and communication technologies (ICTs). However, there is a growing divergence between how social capital is commonly measured in the study of ICTs and how it is measured in other fields. This departure raises questions about the validity of some of the most widely cited studies of social capital and ICTs. We compare the Internet Social Capital Scales (ISCS) developed by Williams [2006. On and off the ’net: scales for social capital in an online era. Journal of Computer-Mediated Communication, 11(2), 593–628. doi: 10.1111/j.1083-6101.2006.00029.x] – a series of psychometric scales commonly used to measure ‘social capital’ – to established, structural measures of social capital: name, position, and resource generators. Based on a survey of 880 undergraduate students (the population to which the ISCS has been most frequently administered), we find that, unlike structural measures, the ISCS does not distinguish between the distinct constructs of bonding and bridging social capital. The ISCS does not have convergent validity with structural measures of bonding or bridging social capital; it does not measure the same concept as structural measures. The ISCS conflates social capital with the related constructs of social support and attachment. The ISCS does not measure perceived or actual social capital. These findings raise concerns about the interpretations of existing studies of ‘social capital’ and ICTs that are based on the ISCS. Given the absence of measurement validity, we urge those studying social capital to abandon the ISCS in favor of alternative approaches. 相似文献

The author integrated attachment theory with social cognitive career theory (SCCT) to examine how attachment styles influence the career search self‐efficacy activities of interviewing, networking, job searching, and personal exploration. Using an undergraduate sample (N = 275, 81% women), the author tested a structural model. Results indicated that anxious attachment style was negatively related to interviewing self‐efficacy, whereas avoidant attachment style was negatively related to networking, job searching, and personal exploration self‐efficacy. Theoretical implications based on these findings provide support for an integrative model of attachment theory with SCCT. Career counselors are encouraged to consider clients’ attachment styles when working with individuals who are searching for employment. To help address the limitations of the study, future researchers could test the applicability of the current model with a more diverse sample. 相似文献
