Positively experienced relationships with family, partners and friends are the most important source of meaning in life for older persons. At the same time, Western countries are confronted with a growing number of socially isolated older adults who lack those relationships. This study aims to explore whether and how older adults who live in social isolation experience meaning in life. Data were collected via in-depth, semi-structured interviews with 24 socially isolated older adults, ranging in age from 62 to 94, all living in Rotterdam, The Netherlands. The criterion-based sampling of participants took place in close consultation with social workers of a mentoring project for socially isolated older adults. Follow-up interviews with 22 participants improved the credibility of findings and contributed to the breadth and depth of the researched casuistry. Data were analysed using an analytical framework based on seven needs of meaning identified by Baumeister (purpose, values, efficacy, self-worth) and Derkx (coherence, excitement, connectedness). The study demonstrates that isolated older adults may find anchors for meaning in life, although not all needs for meaning are satisfied, and there can also be tension between different needs. The needs-based model provides concrete distinctions for enabling care-givers to recognise elements of meaning.

Several instruments have been developed to measure the human beings-nature relationship, one of which is the Love and Care for Nature Scale. Three studies were conducted with the aim of analyzing to what extent the construct of love and care for nature, responds to two empirically different dimensions, as well as conducting a psychometric study of the scale. The analysis of construct components showed a large cluster formed by two others (connectedness and well-being), considered “love for nature”, and one two-items cluster referring to “care” (Study 1, n = 51). Considering the “love” items, it was found that ten of the items present adequate psychometric properties (Study 2, n = 1071), and adequate levels of reliability and validity (Study 3, n = 151). Consequently, an appropriate measure of love of nature is established, while an interesting future research line would be to separately study the scale’s two components.

Supported playgroups are a common form of intervention offered in Australian early childhood education. This study used interviews and quantitative measures to examine whether attending supported playgroups benefits culturally and linguistically diverse (CALD) parents’ or carers’ social support, connectedness, and parental self-efficacy (PSE). Thirty-five playgroup attendees completed three validated measures assessing social support, isolation, and PSE. Seven mothers, two carers, and two playgroup staff participated in semistructured interviews. The quantitative and qualitative data indicated that CALD parents and carers show high levels of isolation and low social support. The qualitative data indicated that most parents or carers felt more supported and connected as a result of attending the playgroup, and just over half stated that the playgroup had improved their confidence. This study highlights the need to consider the social resources of CALD families when planning and delivering services, and calls for future longitudinal studies of the benefits of playgroups.

Les interventions visant à réduire la morbidité et la mortalité après une tentative de suicide et qui s’avèrent efficaces restent peu nombreuses et parfois difficiles à mettre en œuvre, alors qu’une grande majorité de patients quitte l’hôpital après un temps de séjour relativement court et que l’adhésion aux soins proposés est de l’ordre d’un compromis qui reste fragile. Le psychiatre Jérôme Motto a été un précurseur dans un nouveau type d’approche visant à proposer le maintien d’un contact avec ces patients au moyen de l’envoi réguliers de lettre s’inquiétant de leur santé, de leur devenir, et ce de manière personnalisée. Par la suite, de nouvelles modalités de recontact ont été testées, et chacune s’est avérée avoir des propriétés intrinsèques qui semblent les rendre plus opérantes sur certains patients cibles, que ce soit par la mise à disposition de cartes ressources, d’envoi de cartes postales ou d’appels téléphoniques. Depuis, des stratégies visant à combiner ces approches complémentaires en s’appuyant sur des algorithmes définissant le meilleur type de « recontact » ont été testées avec des résultats encourageants. L’intérêt de l’algorithme est qu’il peut être complété au fur et à mesure des avancées scientifiques et intégrer de nouvelles modalités de veille, par SMS par exemple. Ce type de programme a l’avantage d’être peu coûteux et facile à déployer, il ne se substitue pas aux soins classiques et cherche d’ailleurs au contraire à les compléter, tandis que les enquêtes qualitatives montrent qu’ils sont très bien acceptés par les patients auxquels ils s’adressent.

We consider the possible disentanglements of holomorphic map germs f: (ℂn, 0) → (ℂN, 0), 0 < n < N, with nonisolated locus of instability Inst (f). The aim is to achieve lower bounds for their (homological) connectivity in terms of dim Inst (f). Our methods apply in the case of corank 1.

We construct a family of self-affine tiles in $\mathbb{R}^{d}$ ($d\geqslant 2$) with noncollinear digit sets, which naturally generalizes a class studied originally by Q.-R. Deng and K.-S. Lau in $\mathbb{R}^{2}$, and its extension to $\mathbb{R}^{3}$ by the authors. We obtain necessary and sufficient conditions for the tiles to be connected and for their interiors to be contractible.

The current study examines the interaction between mobility limitations and social networks in relation to activity in later life. Although the importance of activity participation to successful ageing has been well established, it is still unclear what contributes to higher levels of activity. This research addresses this issue, using data from the Survey of Health, Ageing and Retirement in Europe. The analysis focuses on a sub-sample of respondents aged 60 and older, from 13 countries, who participated in two specific waves, in 2011 and 2013. Multivariate analysis of the longitudinal data was conducted using hierarchical generalised Poisson regression and incorporating a new comprehensive social network scale. The inquiry found that having multiple mobility limitations is associated with less activity and that having a resourceful social network contributes to more activity. The research further revealed that social network is particularly beneficial to those with multiple mobility limitations because it mitigates the negative association with activity. This conclusion furthers the understanding of the relationship between different key dimensions in the successful ageing paradigm. Specifically, the findings imply the significance of having a social network among those who are functionally challenged. This finding has important implications for active ageing policies.

We analysed the supportive social networks associated with the conservation of six threatened Australian bird taxa, in one of the first network analyses of threatened species conservation programmes. Each example showed contrasting vulnerabilities. The Alligator Rivers yellow chat Epthianura crocea tunneyi had the smallest social network and no real action was supported. For the Capricorn yellow chat Epthianura crocea macgregori the network was centred on one knowledgeable and committed actor. The orange-bellied parrot Neophema chrysogaster had a strongly connected recovery team but gaps in the overall network could limit communication. The recovery teams for the swift parrot Lathamus discolor and Baudin's black-cockatoo Calyptorhynchus baudinii had strong links among most stakeholders but had weak ties to the timber industry and orchardists, respectively, limiting their capacity to manage threatening processes. Carnaby's black cockatoo Calyptorhynchus latirostris seemed to have the most effective social network of any of the taxa studied but may be vulnerable to skill shortages. In each case the network analysis pointed to gaps that could be filled to enhance the conservation effort, and highlighted the importance of recovery teams. The research suggests that formal network analysis could assist in the design of more effective support mechanisms for the conservation of threatened species.

We show that the space of actions of every finitely generated, nilpotent group by $C^1$ orientation-preserving diffeomorphisms of the circle is path-connected. This is done via a general result that allows any given action on the interval to be connected to the trivial one by a continuous path of topological conjugates.

During the transition from primary to secondary school, students typically experience a new social environment, moving from primary school with small intact classes throughout the day with one main teacher, to a larger secondary school with teachers, classrooms and often classmates changing throughout the day. During this time, students report a reduced sense of connectedness, which has been associated with symptoms of depression and anxiety. This study investigated the temporal association between feeling connected to school and mental health prior to and over the transition period. Data were obtained from 3,459 students in a longitudinal study of adolescents’ knowledge, attitudes and experiences of bullying victimisation and perpetration during the transition from primary school to secondary school. Students completed a questionnaire at four time points from Grade 7 to the end of Grade 9. Path analysis was used to model relationships between school connectedness, depression and anxiety. The findings suggest reciprocal relationships between connectedness and mental health where increased connectedness to school is associated with decreased depression and anxiety; conversely, increased depression and anxiety is associated with decreased connectedness to school. The significant reciprocal associations found in the cross-lag models in the first two years of secondary school indicate the need to intervene during the transition period to improve students’ social and mental health outcomes.

Families, peer groups, and schools are important environments for children's positive growth and development. A theoretical model that linked children's perceptions of parenting, sense of connectedness to family, peers and school, along with peer group type, to adjustment was developed and tested. Data were collected from students and their parents. The model was supported and explained 56% of the variance with respect to children's reports. Family, school, and peer connectedness all independently predicted child reported adjustment. Differences were apparent between children's and parents’ reports, and the model did not convincingly predict parental views of their child's adjustment. There was evidence that non-familial social environments can have a positive, compensatory impact on children's emotional functioning — a most important finding for school personnel interested in student wellbeing.

Let $R$ be a commutative ring. The regular digraph of ideals of $R$, denoted by $\Gamma (R)$, is a digraph whose vertex set is the set of all nontrivial ideals of $R$ and, for every two distinct vertices $I$ and $J$, there is an arc from $I$ to $J$ whenever $I$ contains a nonzero divisor on $J$. In this paper, we study the connectedness of $\Gamma (R)$. We also completely characterise the diameter of this graph and determine the number of edges in $\Gamma (R)$, whenever $R$ is a finite direct product of fields. Among other things, we prove that $R$ has a finite number of ideals if and only if $\mathrm {N}_{\Gamma (R)}(I)$ is finite, for all vertices $I$ in $\Gamma (R)$, where $\mathrm {N}_{\Gamma (R)}(I)$ is the set of all adjacent vertices to $I$ in $\Gamma (R)$.

Using data on age at 100 kg of three pig breeds (Large White, Landrace and Duroc) the connectedness between herds in China was evaluated by the connectedness rating (CR) method. The results show that most herds in China have low average CR (0–3.59%) with other herds. In Large White, of the 36 herds analyzed there are 20 herds, which are connected with at least one other herd. In Landrace and Duroc, of the 27 and 18 herds analyzed, only four and five herds, respectively, were found having connectedness with other herds. Generally, the connectedness exists only among two or few herds in the same region. A certain degree of connectedness between herds is a precondition for cross-herd genetic evaluation. A national or regional cross-herd genetic evaluation is not practicable at the present time in China. More intense efforts are needed to establish and enhance the connectedness between herds by means of extensively using artificial insemination (AI) in the swine industry in China.

Mobility can affect a learner's participation in different communities that support language learning. In this paper we report on our experience with supporting a course in which language students are encouraged to travel to a country where the target language is spoken. On the one hand, students who travel abroad get in contact with local communities,which can promote their learning of the language and the culture. On the other hand, they risk losing contact with their classmates and the support that they provide. In this context we introduced a mobile community blog with the aim of extending the learning arena and promoting the sharing of knowledge among the students, independently of their location. This paper discusses the design considerations for the blog and describes its use to support students' sense of community. An evaluation and analysis of the usage of the blog is presented. These results suggest that the learners lack an identity within the community of language learners and there was no sense of community among the members. Reflecting on these results, we suggest that while a blog might be an appropriate tool for promoting knowledge sharing, it lacks functionalities to promote connectedness among learners and foster their identity as a community.

More realistic approaches are needed to understand the complexity of ecological systems. Emergent properties of real systems can be used as a basis for a new, neither reductionist nor holistic, approach. Three systems, termed here BUBBLEs, WAVEs and CRYSTALs, have been identified as exhibiting emergent properties. They are non-hierarchical assemblages of individual components, with amplification and connectedness being two main principles that govern their build-up, maintenance and mutual relationships. Examples from various fields of biological and ecological science are referred to, ranging from individual organisms to landscapes.
