RESUMO

OBJECTIVE: Brief alcohol interventions (BAIs) have historically centered on young adults attending 4-year predominantly white institutions. The purpose of this scoping review is to determine BAIs evaluated among young adults with one or more marginalized/understudied racial, ethnic, sexual, gender, and military/Veteran identities and/or who are embedded in an understudied context based on houselessness, attending a 2-year institution, or not attending college. A secondary objective is to explore definitions of the constructs young adult and brief to inform subsequent systematic reviews. METHOD: Sources had to be published in English between January 1, 1999 and December 31, 2019 and report the evaluation of an intervention ≤ 5 hr long, delivered over ≤ 4 weeks, among participants aged 18-30 years (or 16-30 in college contexts) within a specified marginalized/understudied subpopulation/context wherein alcohol use and/or consequences were a primary outcome. Systematic searches were conducted in APA PsycNet, the EBSCO Psychology and Behavioral Sciences Collection, PubMed, Sociological Abstracts, and Web of Science. Screening was independently performed by two coders who also extracted data. RESULTS: Of 4,825 identified records, 158 provided data; 86 described interventions fitting our definition of brief; of these, only 21 met criteria based on our definition of young adult, with nine meeting full inclusion criteria based on young adult subpopulation. CONCLUSIONS: Findings signify a need for additional research evaluating BAIs among young adult subpopulations and highlight the importance of carefully defining and reporting participant characteristics. Increased attention to sociocultural considerations and strengths relevant to the diverse contexts and intersecting identities of young adults may strengthen extant BAIs and equitably mitigate alcohol-related harm.

RESUMO

BACKGROUND: Cigarette smoking is 5 times more prevalent among homeless individuals than in the general population, and homeless individuals are disproportionately affected by smoking-related morbidity and mortality. Homeless smokers report interest in changing their smoking behavior; however, established smoking cessation interventions are neither desirable to nor highly effective for most members of this population. The aim of this study was to document homeless smokers' perceptions of established smoking interventions as well as self-generated, alternative smoking interventions to elucidate points for intervention enhancement. METHODS: Participants (N=25) were homeless smokers who responded to semistructured interviews regarding smoking and nicotine use as well as experiences with established and alternative smoking interventions. Conventional content analysis was used to organize data and identify themes. RESULTS: Participants appreciated providers' initiation of conversations about smoking. They did not, however, feel simple advice to quit was a helpful approach. Instead, they suggested providers use a nonjudgmental, compassionate style, offer more support, and discuss a broader menu of options, including nonabstinence-based ways to reduce smoking-related harm and improve health-related quality of life. Most participants preferred engaging in their own self-defined, alternative smoking interventions, including obtaining nicotine more safely (e.g., vaping, using smokeless tobacco) and using behavioral (e.g., engaging in creative activities and hobbies) and cognitive strategies (e.g., reminding themselves about the positive aspects of not smoking and the negative consequences of smoking). Abrupt, unaided quit attempts were largely unsuccessful. CONCLUSIONS: The vast majority of participants with the lived experience of homelessness and smoking were uninterested in established smoking cessation approaches. They did, however, have creative ideas about alternative smoking interventions that providers may support to reduce smoking-related harm and enhance quality of life. These ideas included providing information about the relative risks of smoking and the relative benefits of alternative strategies to obtaining nicotine and avoiding smoking.

RESUMO

The scale and magnitude of complex and pressing environmental issues lend urgency to the need for integrative and reproducible analysis and synthesis, facilitated by data-intensive research approaches. However, the recent pace of technological change has been such that appropriate skills to accomplish data-intensive research are lacking among environmental scientists, who more than ever need greater access to training and mentorship in computational skills. Here, we provide a roadmap for raising data competencies of current and next-generation environmental researchers by describing the concepts and skills needed for effectively engaging with the heterogeneous, distributed, and rapidly growing volumes of available data. We articulate five key skills: (1) data management and processing, (2) analysis, (3) software skills for science, (4) visualization, and (5) communication methods for collaboration and dissemination. We provide an overview of the current suite of training initiatives available to environmental scientists and models for closing the skill-transfer gap.

RESUMO

This study is the first to document suicidality among chronically homeless people with alcohol problems (N = 134) and examine its trajectory following exposure to immediate, permanent, low-barrier housing (i.e., Housing First). Suicidal ideation, intent, plans, and prior attempts were assessed at baseline and during a 2-year follow-up. Baseline suicidal ideation was over four times higher than in the general population. Two-year, within-subjects, longitudinal analyses indicated severity of suicidal ideation decreased by 43% from baseline to follow-up. Significant decreases were also found for intent and clinical significance of ideation. No participants died by suicide during the 2-year follow-up.

RESUMO

Syntheses, structural, and spectroscopic characterization of multinuclear tris(amidate) lanthanide complexes is described. Addition of K3[N(o-PhNC(O)(t)Bu)3] to LnX3 (LnX3 = LaBr3, CeI3, and NdCl3) in N,N-dimethylformamide (DMF) results in the generation of dinuclear complexes, [Ln(N(o-PhNC(O)(t)Bu)3)(DMF)]2(µ-DMF) (Ln = La (1), Ce (2), Nd(3)), in good yields. Syntheses of tetranuclear complexes, [Ln(N(o-PhNC(O)(t)Bu)3)]4 (Ln = Ce (4), Nd(5)), resulted from protonolysis of Ln[N(SiMe3)2]3 (Ln = Ce, Nd) with N(o-PhNCH(O)(t)Bu)3. In the solid-state, complexes 1-5 exhibit coordination modes of the tripodal tris(amidate) ligand that are unique to the 4f elements and have not been previously observed in transition metal systems.

RESUMO

A series of tetravalent An(IV) complexes with a bis-phenyl ß-ketoiminate N,O donor ligand has been synthesized with the aim of identifying bonding trends and changes across the actinide series. The neutral molecules are homoleptic with the formula An((Ar)acnac)(4) (An = Th (1), U (2), Np (3), Pu (4); (Ar)acnac = ArNC(Ph)CHC(Ph)O; Ar = 3,5-(t)Bu(2)C(6)H(3)) and were synthesized through salt metathesis reactions with actinide chloride precursors. NMR and electronic absorption spectroscopy confirm the purity of all four new compounds and demonstrate stability in both solution and the solid state. The Th, U, and Pu complexes were structurally elucidated by single-crystal X-ray diffraction and shown to be isostructural in space group C2/c. Analysis of the bond lengths reveals shortening of the An-O and An-N distances arising from the actinide contraction upon moving from 1 to 2. The shortening is more pronounced upon moving from 2 to 4, and the steric constraints of the tetrakis complexes appear to prevent the enhanced U-O versus Pu-O orbital interactions previously observed in the comparison of UI(2)((Ar)acnac)(2) and PuI(2)((Ar)acnac)(2) bis-complexes. Computational analysis of models for 1, 2, and 4 (1a, 2a, and 4a, respectively) concludes that both the An-O and the An-N bonds are predominantly ionic for all three molecules, with the An-O bonds being slightly more covalent. Molecular orbital energy level diagrams indicate the largest 5f-ligand orbital mixing for 4a (Pu), but spatial overlap considerations do not lead to the conclusion that this implies significantly greater covalency in the Pu-ligand bonding. QTAIM bond critical point data suggest that both U-O/U-N and Pu-O/Pu-N are marginally more covalent than the Th analogues.

RESUMO

Ecology is evolving rapidly and increasingly changing into a more open, accountable, interdisciplinary, collaborative and data-intensive science. Discovering, integrating and analyzing massive amounts of heterogeneous data are central to ecology as researchers address complex questions at scales from the gene to the biosphere. Ecoinformatics offers tools and approaches for managing ecological data and transforming the data into information and knowledge. Here, we review the state-of-the-art and recent advances in ecoinformatics that can benefit ecologists and environmental scientists as they tackle increasingly challenging questions that require voluminous amounts of data across disciplines and scales of space and time. We also highlight the challenges and opportunities that remain.

RESUMO

A diiron(II) complex containing two µ-1,3-(κN:κO)-amidate linkages has been synthesized using the 2,2',2''-tris(isobutyrylamido)triphenylamine (H(3)L(iPr)) ligand. The resulting diiron complex, 1, reacts with dioxygen (or iodosylbenzene) to effect intramolecular C-H bond activation at the methine position of the ligand isopropyl group. The ligand-activated product, 2, has been isolated and characterized by a variety of methods including X-ray crystallography. Electrospray ionization mass spectroscopy of 2 prepared from(18)O(2) was used to confirm that the oxygen atom incorporated into the ligand framework is derived from molecular oxygen.

RESUMO

Ecology is a synthetic discipline benefiting from open access to data from the earth, life, and social sciences. Technological challenges exist, however, due to the dispersed and heterogeneous nature of these data. Standardization of methods and development of robust metadata can increase data access but are not sufficient. Reproducibility of analyses is also important, and executable workflows are addressing this issue by capturing data provenance. Sociological challenges, including inadequate rewards for sharing data, must also be resolved. The establishment of well-curated, federated data repositories will provide a means to preserve data while promoting attribution and acknowledgement of its use.

RESUMO

The ligand bis(2-isobutyrylamidophenyl)amine has been prepared and used to stabilize both mononuclear and dinuclear cobalt(II) complexes. The nuclearity of the cobalt product is regulated by the deprotonation state of the ligand. Both complexes catalytically oxidize triphenylphosphine to triphenylphosphine oxide in the presence of O(2).

RESUMO

The synthesis and characterization of nickel complexes supported by a family of open-chain, tetradentate, tris(amidate) ligands, [N(o-PhNC(O)R)(3)](3-) ([L(R)](3-) where R = (i)Pr, (t)Bu, and Ph) is described. The complexes [Ni(L(iPr))](-), [Ni(L(tBu))](-), and [Ni(L(Ph))(CH(3)CN)](-) have been characterized by solution-state spectroscopic methods and single crystal X-ray diffraction. Each ligand gives rise to a different primary coordination sphere about the nickel centre. These studies indicate that the ligands' acyl substituents can be used to regulate the coordination mode of the amidate donors to nickel and the coordination number of the nickel centres. In addition, the ability of these complexes to bind cyanide has been explored. These experiments demonstrate that only one of these complexes, [Ni(L(iPr))](-), is able to irreversibly bind cyanide and can be used to assemble [Et(4)N](3)[Ni(L(iPr))(mu(2)-CN)Co(L(iPr))], a cyanide bridged, heterobimetallic complex. The synthesis and characterization of the cyanide containing complexes, including magnetic susceptibility studies, are described.

RESUMO

Ecology is inherently cross-disciplinary, drawing together many types of information to address questions about the natural world. Finding and integrating relevant data to assist in these analyses is crucial, but is difficult owing to ambiguous terminology and the lack of sufficient information about datasets. Ontologies provide a formal mechanism for defining terms and their relationships, and can improve the location, interpretation and integration of data based on its inherent meaning. Ontologies have assisted other disciplines (e.g. molecular biology) in unifying and enriching descriptions of data, and ecology can benefit from similar approaches. We review ontology efforts in ecology, and describe how these can benefit research by enhancing the location and interpretation of relevant data for confronting crucial ecological questions.

RESUMO

The syntheses of two phenylamine-based ligand systems, N(o-PhNH(2))(3) and N(o-PhNHC(O)(i)Pr)(3), are reported. These ligands readily coordinate to Co(II) to form monomeric complexes. X-ray diffraction studies establish that the [N(o-PhNC(O)(i)Pr)(3)](3-) ligand stabilizes the Co(II) ion in a trigonal-monopyramidal coordination environment. The axial coordination site in this complex is accessible and, upon cyanide coordination, generates an electrochemically active species.
