Abstract The study about the resilience of Rubiaceae to the influence of anthropogenic factors was conducted along the altitudinal gradient of 300–3900 m asl. in Western Bhutan. The survey covered three types of forest, categorized based on the prevalence of anthropogenic disturbances and assessed the diversity of Rubiaceae species in each forest type. The study recorded a total of 54 Rubiaceae species belonging to 41 genera from the study sites. The high diversity of Rubiaceae in the intermediately disturbed forest as revealed by Simpson and Shannon-Wiener diversity analysis and further strengthened by a between-group one-way ANOVA analysis contradicts the presumed description of Rubiaceae as ecologically sensitive. The wider adaptability range exhibited by Ceriscoides (Hook.f.) Tirvendadum, Himalrandia Yamazaki, Uncaria Schreber, and Leptodermis Wall. showing presence in all the forest categories indicates a higher survival rate of these genera. On the contrary, the species showing a higher rate of confinement to a specific habitat bears higher risk of extinction due to ever-rising anthropogenic disturbances. As such, an exhaustive research assessing the impact of different categories of anthropogenic factors on different species of Rubiaceae is required to understand the overall resilience of the family to the anthropogenic disturbances.

Economic security is a fundamental cord that would enhance the empowerment levels of women. In the patriarchal family structure, women have little or no access to economic resources, making them vulnerable. Social sanction for femicide, social and cultural discriminatory practices, and violence against women have curtailed women's choices and freedom. The impact of the elimination of girl children and strong son preference has deprived women of their economic entitlements. The case study is of particular interest as it is undertaken in Usilampatti taluk in Tamil Nadu, India, which is notorious for the practice of female foeticide and infanticide leading to low sex ratio. This chapter is an attempt to identify how rural women who have escaped femicide negotiate with gender asymmetry, reorganize the power relations within the family and market structure, manage economic resources, and emerge as independent leaders both in the private and public domains.

A disability experienced by one family member impacts on all individuals in the family unit and influences their typical pattern of interaction. The process of individual and family adjustment to disability, a family crisis, is seen in a case study of Sam and his diagnosis of multiple sclerosis. The individual, family and social adjustment issues, including redefinition of family, social, sexual and work roles, are examined in a real live context. Tentative recommendations for professionals working with families in which an individual becomes disabled are developed from personal interviews with Sam and his family.

This article draws on in-depth qualitative interviews with ten practitioners who specialise in working with young carers, to examine how members of the emerging profession of ‘young carers’ worker’ view their partnerships with social services. It focuses particularly on one case study area (Town Z), where partnerships between social services and the voluntary sector around young carers were relatively highly developed. It explores the practitioners’ comments about the impact of their organisations’ partnerships with social services on their work. This is done in the context of their conceptualisations of care and family relationships. In particular, the themes of identifying young carers and working with the family as a whole are discussed, and young carers’ workers views are compared to the conceptualisations that come across in literature from both disability studies and social work perspectives. It is concluded that young carers’ workers conceptualisations of care and disability do differ markedly from the perspectives that appear to dominate both social work theory and practice, and that this impacting on how the former view their partnerships with the latter.

Abstract This article presents the problem of the functioning of a family with a child suffering from two painful, chronic and incurable diseases - cystic fibrosis and short bowel syndrome. Its aim is to learn about the impact of these diseases on the occurrence and course of mental disorders in a child and on the functioning of the whole family in which such a child is brought up. Like any long-term illness of a child, it has influenced changes in the functioning of the family system. The parents’ functioning and the flexibility of the family system conditioned the acceptance of the diagnosis and determined further participation of the family in the treatment process. This article also discusses the risk of unfavorable attitudes of parents towards the child’s illnesses, which may contribute to the development of mental disorders in the child patient, as well as in his/her parents or siblings. In the process of treatment and rehabilitation, the necessity for cooperation of medical staff, the patient and his/her parents has been emphasised.

Abstract Taxon sampling is a central aspect of phylogenetic study design, but it has received limited attention in the context of total-evidence dating, a widely used dating approach that directly integrates molecular and morphological information from extant and fossil taxa. We here assess the impact of commonly employed outgroup sampling schemes and missing morphological data in extant taxa on age estimates in a total-evidence dating analysis under the uniform tree prior. Our study group is Pimpliformes, a highly diverse, rapidly radiating group of parasitoid wasps of the family Ichneumonidae. We analyze a data set comprising 201 extant and 79 fossil taxa, including the oldest fossils of the family from the Early Cretaceous and the first unequivocal representatives of extant subfamilies from the mid Paleogene. Based on newly compiled molecular data from ten nuclear genes and a morphological matrix that includes 222 characters, we show that age estimates become both older and less precise with the inclusion of more distant and more poorly sampled outgroups. These outgroups not only lack morphological and temporal information, but also sit on long terminal branches and considerably increase the evolutionary rate heterogeneity. In addition, we discover an artefact that might be detrimental for total-evidence dating: “bare-branch attraction”, namely high attachment probabilities of certain fossils to terminal branches for which morphological data are missing. Using computer simulations, we confirm the generality of this phenomenon and show that a large phylogenetic distance to any of the extant taxa, rather than just older age, increases the risk of a fossil being misplaced due to bare-branch attraction. After restricting outgroup sampling and adding morphological data for the previously attracting, bare branches, we recover a Jurassic origin for Pimpliformes and Ichneumonidae. This first age estimate for the group not only suggests an older origin than previously thought, but also that diversification of the crown group happened well before the Cretaceous-Paleogene boundary. Our case study demonstrates that in order to obtain robust age estimates, total-evidence dating studies need to be based on a thorough and balanced sampling of both extant and fossil taxa, with the aim of minimizing evolutionary rate heterogeneity and missing morphological information.

This study is the first comprehensive empirical study to examine the relationship between the family business and the firm’s performance in Uzbekistan. In this research, we investigate the relationship between family firms and financial performance using enough extensive unbalanced panel data from 2012 through 2015 on 3148 non-banking/non-government firms. Moreover, we analyze the impact of tax cut policy on SMEs, including family firms from a case study of Uzbekistan by using the difference-in-difference estimator. These two will be a major contribution to the family business study field in Uzbekistan.

BackgroundSchwartz Center Rounds®(Rounds) were introduced into the UK in 2009 to support health-care staff to deliver compassionate care, something the Francis report (Francis R.Report of the Mid Staffordshire NHS Foundation Trust Public Inquiry. London: The Stationery Office; 2013) identified as lacking. Rounds are organisation-wide forums that prompt reflection and discussion of the emotional, social and ethical challenges of health-care work, with the aim of improving staff well-being and patient care.ObjectivesHow, in which contexts and for whom Rounds participation affects staff well-being at work, increases social support for staff and improves patient care.Design(1) A scoping review of Rounds literature and comparison with alternative interventions; (2) mapping Rounds providers via a survey, telephone interviews and secondary data; (3) a two-wave survey of (i) new attenders/non-attenders in 10 sites to determine the impact on staff engagement and well-being; and (ii) interviews with Rounds attenders, non-attenders, facilitators, clinical leads, steering group members, board members and observations in nine case study sites to (4) describe experiences and (5) test candidate programme theories by which Rounds ‘work’ (realist evaluation).Setting(1) International literature (English); (2) all Rounds providers (acute/community NHS trusts and hospices) at 1 September 2014 (survey/interview) and 15 July 2015 (secondary data); (3) 10 survey sites; and (4 and 5) nine organisational case study sites (six of which also took part in the survey).Participants(1) Ten papers were reviewed for Rounds and 146 were reviewed for alternative interventions. (2) Surveys were received from 41 out of 76 (54%) providers and interviews were conducted with 45 out of 76 (59%) providers. (3) Surveys were received from 1140 out of 3815 (30%) individuals at baseline and from 500 out of 1140 (44%) individuals at follow-up. (4 and 5) A total of 177 interviews were conducted, as were observations of 42 Rounds, 29 panel preparations and 28 steering group meetings.Results(1) The evidence base is limited; compared with 11 alternative interventions, Rounds offer a unique organisation-wide ‘all staff’ forum in which disclosure/contribution is not essential. (2) Implementation rapidly increased between 2013 and 2015; Rounds were implemented variably; challenges included ward staff attendance and the workload and resources required to sustain Rounds; and costs were widely variable. (3) There was no change in engagement, but poor psychological well-being (12-item General Health Questionnaire) reduced significantly (p < 0.05) in Rounds attenders (25% to 12%) compared with non-attenders (37% to 34%). (4 and 5) Rounds were described as interesting, engaging and supportive; four contextual layers explained the variation in Rounds implementation. We identified four stages of Rounds, ‘core’ and ‘adaptable’ components of Rounds fidelity, and nine context–mechanism–outcome configurations: (i) trust, emotional safety and containment and (ii) group interaction were prerequisites for creating (iii) a countercultural space in Rounds where staff could (iv) tell stories, (v) self-disclose their experiences to peers and (vi) role model vulnerability; (vii) provide important context for staff and patient behaviour; (viii) shining a spotlight on hidden staff and patient stories reduced isolation and enhanced support/teamwork; and (ix) staff learned through reflection resulting in ripple effects and outcomes. Reported outcomes included increased empathy and compassion for colleagues and patients, support for staff and reported changes in practice. The impact of Rounds is cumulative and we have identified the necessary conditions for Rounds to work.LimitationsRounds outcomes relied on self-report, fewer regular attenders were recruited than desired, and it was not possible to observe staff post Rounds.ConclusionRounds offer unique support for staff and positively influence staff well-being, empathy and compassion for patients and colleagues.Future workThe adaptation of Rounds to new contexts and to increase reach needs evaluation.FundingThe National Institute for Health Research Health Services and Delivery Research programme.

Abstract. The impact of anoxia on meiobenthic copepod species was assessed by means of a field experiment. Four plexiglass chambers were deployed in situ in 24 m depth to simulate an anoxic event of 9 days, 1 month, 2 months and 10 months. From normoxic to anoxic conditions, we recorded a drop in copepod density and species richness. With increasing duration of anoxia the relative abundance of the individuals of the family Cletodidae increased, and they survived the 1 month and 2 month anoxia, the latter with few specimens. They were the true "winners" of the experimentally induced anoxia. Dominance did not increase in the deployments because not one, but several species from this family were tolerant to anoxia. The overall rate of survival was the same for males and females, but no juvenile stages of copepods survived in anoxia. During a recovery phase of 7 days after a short-term anoxia of 9 days, harpacticoid copepod density did not increase significantly, and there was only a slight increase in species diversity. We concluded that no substantial colonisation from the surrounding sediment took place. The survivors, however, showed a high potential for recovery according to the number of gravid females, whose number increased significantly once the oxygen was available again. These findings imply that substantial energy is allocated to reproduction in the recovery phase.

Only a few studies have quantified and measured ecosystem services (ES) specifically related to soil. To address this gap, we have developed and applied a methodology to assess changes in ecosystem services, based on measured or estimated soil property changes that were stimulated by soil management measures (e.g., mulching, terracing, no-till). We applied the ES assessment methodology in 16 case study sites across Europe representing a high diversity of soil threats and land use systems. Various prevention and remediation measures were trialled, and the changes in manageable soil and other natural capital properties were measured and quantified. An Excel tool facilitated data collection, calculation of changes in ecosystem services, and visualization of measured short-term changes and estimated long-term changes at plot level and for the wider area. With this methodology, we were able to successfully collect and compare data on the impact of land management on 15 different ecosystem services from 26 different measures. Overall, the results are positive in terms of the impacts of the trialled measures on ecosystem services, with 18 out of 26 measures having no decrease in any service at the plot level. Although methodological challenges remain, the ES assessment was shown to be a comprehensive evaluation of the impacts of the trialled measures, and also served as an input to a stakeholder valuation of ecosystem services at local and sub-national levels.
