Unmet Needs of Unaccompanied Minors from Central America: Perceptions of Professionals from Multiple Sectors
Background: In recent years, there has been a significant influx of Central American youth who cross the U.S.-Mexico border without a parent or legal guardian. While federal procedures are established to oversee the treatment and placement of unaccompanied minors, less is known about the needs of unaccompanied minors and available services afterthey are placed in appropriate custody.
Methods: Purposive and strategic sampling of professionals from medical, social work, education and legal fields was conducted. Fourteen informants were recruited across the U.S. for confidential semi-structured interviews, which were audio recorded and transcribed in 2016 to 2017. Standard anthropological methods were employed, including immersion and crystallization techniques that incorporated within-case and across-case analytic strategies.
Results: Recruited informants had previous or current direct experience working with immigrant minors for three or more years in addition to extensive public health experience.
Unaccompanied minors were described as predominantly adolescent boys, ranging from 2 to 18 years old. Children faced unmet mental, medical and psychosocial needs that are interconnected and largely unmet due to children’s legal status and ineligibility to access services in most jurisdictions. The most pressing challenge affecting the health of youth was their immigration status.
Across sectors,informants revealed an imbalance between the growing demand for services, including legal counsel, and the limited supply of professionals and well-funded services to meet children’s complex needs. Informants emphasized the value of trauma-informed practice, Spanish language proficiency, child-informed practice and intercultural awareness and humility towards their clients as key features of equipped professionals working with this vulnerable population. Regardless of sector, professionals emphasized the importance of culturally-informed care to immigrant youth. Building these skills is associated with greater confidence to provide services to unaccompanied minors, many of whom have experienced as significant burden of childhood trauma.
Conclusions: The health needs of unaccompanied minors are complex and span across medical, social work, education, and legal fields. Interdisciplinary collaboration is needed to address the challenges faced by unaccompanied minors in their efforts to integrate themselves into their new communities and promote their resilience. Promising initiatives include co-location of inter-sector services for increased access and efficiency of services and development of professional trainings and resources for professionals in sectors that serve this population
In vivo biocompatibility and pacing function study of silver ion-based antimicrobial surface technology applied to cardiac pacemakers
INTRODUCTION
Evidence suggests that the rate of cardiovascular implantable electronic device (CIED) infections is increasing more rapidly than the rates of CIED implantation and is associated with considerable mortality, morbidity and health economic impact. Antimicrobial surface treatments are being developed for CIEDs to reduce the risk of postimplantation infection within the subcutaneous implant pocket.
METHODS AND ANALYSIS
The feasibility of processing cardiac pacemakers with the Agluna antimicrobial silver ion surface technology and in vivo biocompatibility were evaluated. Antimicrobially processed (n=6) and control pacemakers (n=6) were implanted into subcutaneous pockets and connected to a part of the muscle using an ovine model for 12 weeks. Pacemaker function was monitored preimplantation and postimplantation.
RESULTS
Neither local infection nor systemic toxicity were detected in antimicrobial or control devices, and surrounding tissues showed no abnormal pathology or over-reactivity. Semiquantitative scores of membrane formation, cellular orientation and vascularity were applied over five regions of the pacemaker capsule and average scores compared. Results showed no significant difference between antimicrobially processed and control pacemakers. Silver analysis of whole blood at 7 days found that levels were a maximum of 10 parts per billion (ppb) for one sample, more typically ≤2 ppb, compared with <2 ppb for preimplantation levels, well below reported toxic levels.
CONCLUSIONS
There was no evidence of adverse or abnormal pathology in tissue surrounding antimicrobially processed pacemakers, or deleterious effect on basic pacing capabilities and parameters at 12 weeks. This proof of concept study provides evidence of basic biocompatibility and feasibility of applying this silver ion-based antimicrobial surface to a titanium pacemaker surface
Family–Teacher Relationships and Child Engagement in Early Care and Education
Young children’s positive interactions with teachers and peers in early care and education (ECE) settings support the development of their social and academic skills. Identifying malleable factors that contribute to children’s positive engagement in these interactions is important in supporting early development. The current study examines one potential malleable factor that could be bolstered through supports for families and teachers alike: family–teacher relationships. We investigate associations between three specific domains of family–teacher relationships and children’s engagement in ECE, so that findings are specific and relevant to intervention. We examine data from Oregon’s Quality Rating Improvement System Validation Study; a diverse sample of 492 preschool-aged children in center-based ECE participated. Children’s engagement was directly observed; parents reported their perception of family–teacher relationships. Multilevel models examined the associations between family–teacher relationships and children’s positive engagement with teachers and peers in ECE classrooms. Results indicate a positive significant relationship between practices and children’s positive engagement with teachers. Although this association was not causal, it suggests that teachers who collaborate and communicate with families, respond to family feedback and cultural values, and demonstrate a family-focused concern may help children engage more positively with teachers. Findings are discussed, limitations addressed, and future directions provided

Construct validity of the Dissociative Experiences Scale (DES): I. The relationship between the DES and other self-report measures of DES
p. 185-188The present study attempted to expand the construct validity of the Dissociative Experiences Scale (DES) by comparing it to: (a) other self-report measures of dissociation (e.g., the Tellegen Absorption Scale [TAS] and the Perceptual Alteration Scale [PAS]); (b) the construct
of "ambiguity intolerance" (assessed by the Yellen Ambiguity Intolerance Scale [YAIS]); and (c) the Jenkins Activity Schedule (JAS: which measures the degree of Type A behavior). Three hundred
and eleven undergraduates participated in an experiment on "Hypnotizability and Personality, " and filled out the DES TAS, PAS, YAIS, and JAS. The DES total score (and three DES factor scores) correlated with the TAS and PAS in the range of .24 - .52 (all correlations were significant at the .001 level, two-tailed). Furthermore, the DES total score (and the three DES factor scores) correlated significantly with the YAIS overall score (r's ranged from .22 - .24, all p's < .001), but did not correlate significantly with the JAS (r's ranged from -.03 - .04, ns). The findings suggest that DES scores (i.e., total scores and each of the three DES factor scores) show good
levels of convergent validity as they correlate significantly with other self-report measures of dissociation. However, the intercorrelations were not high enough to consider the different dissociation measures as interchangeable. Furthermore, subjects reporting high levels of
dissociative experiences also reported higher levels of ambiguity intolerance. However, no significant association was observed between DES scores and the Type A behavior pattern

Could renting be the 'new buying'? Perspectives on consumers' role in prolonging product lifetimes.
The circular economy (CE) has caught the interest of different stakeholders recently as a response to many of the current ‘grand challenges’ exemplified by the UN sustainable development goals. Whilst CE research outputs have increased exponentially, microlevel studies focusing on the role of users in the CE are limited to date. A lack of understanding of consumers’ attitudes is one of biggest challenges facing companies wishing to transition towards more circular production forms. This paper empirically examines consumer attitudes and perceptions towards renting everyday durable consumer goods (e.g., clothes, toys, baby clothes, leisure equipment) and explores online rental business owners’ perspectives of the challenges linked to these circular business models. It comprises an online survey with a large UK sample of 18-54 years (n=1,300) and 10 semi-structured interviews with platform owners. Drawing on and extending two established key frameworks to explain pro-environmental behaviour, i.e. the Norm Activation Theory and the Theory of Planned Behavior, we demonstrate that personal norms (i.e. perceived moral obligation to choose renting consumer goods), perceived behavioural control (i.e. perceived ability to renting consumer goods) and outcome efficacy (i.e., perceived feeling to be able to address environmental problems) are the main direct predictors of the intention to rent consumer goods for a fee. We provide empirical support for the role of personal norms as mediator and further provide insights into how personal norms are activated in the context of access-based consumption. This study has important managerial and policy implications for the transition to circular economy
The intricate determination of magnetic anisotropy in quasi-octahedral vanadium(III): An HF-EPR and magnetic study
We report here the synthesis and a preliminary characterization of the tetranuclear complex of formula [Ga3V(LEt)2(dpm)6], Ga3VEt, in which H3LEt = 2-Ethyl-2-(hydroxymethyl)-propane-1,3-diol and Hdpm = dipivaloylmethane, containing a single paramagnetic vanadium(III) center, from a structural, magnetic, and spectroscopic point of view. Structural characterization by X-ray diffraction evidenced that this derivative is isostructural with the star-shaped Single-Molecule Magnet [Fe3V(LEt)2(dpm)6], Fe3VEt, and can, thus, be considered a model to analyze the magnetic anisotropy of the vanadium(III) ion in that system. The observed results confirm the complexity in obtaining a rationalization of the magnetic behavior of this metal ion, with magnetization data and High Field Electron Paramagnetic Resonance (HF-EPR) spectroscopy providing apparently conflicting results. Indeed, the former were rationalized assuming a rhombic distortion of the ligand field and a dominant easy-axis type anisotropy (equivalent to D ≈ −14.1 cm−1, E ≈ 1.2 cm−1), while a simple axial Spin Hamiltonian approach could explain HF-EPR data (|D| ≈ 6.98 cm−1)
Emergence of good conduct, scaling and Zipf laws in human behavioral sequences in an online world
We study behavioral action sequences of players in a massive multiplayer
online game. In their virtual life players use eight basic actions which allow
them to interact with each other. These actions are communication, trade,
establishing or breaking friendships and enmities, attack, and punishment. We
measure the probabilities for these actions conditional on previous taken and
received actions and find a dramatic increase of negative behavior immediately
after receiving negative actions. Similarly, positive behavior is intensified
by receiving positive actions. We observe a tendency towards anti-persistence
in communication sequences. Classifying actions as positive (good) and negative
(bad) allows us to define binary 'world lines' of lives of individuals.
Positive and negative actions are persistent and occur in clusters, indicated
by large scaling exponents alpha~0.87 of the mean square displacement of the
world lines. For all eight action types we find strong signs for high levels of
repetitiveness, especially for negative actions. We partition behavioral
sequences into segments of length n (behavioral `words' and 'motifs') and study
their statistical properties. We find two approximate power laws in the word
ranking distribution, one with an exponent of kappa-1 for the ranks up to 100,
and another with a lower exponent for higher ranks. The Shannon n-tuple
redundancy yields large values and increases in terms of word length, further
underscoring the non-trivial statistical properties of behavioral sequences. On
the collective, societal level the timeseries of particular actions per day can
be understood by a simple mean-reverting log-normal model.Comment: 6 pages, 5 figure
