Sequence of Structural and Magnetic Phase Transitions in (NO)Mn6(NO3)13.

New nitrosonium manganese(II) nitrate, (NO)Mn6(NO3)13, has been synthesized and structurally characterized. In the temperature range of 45-298 K, the crystal is hexagonal (centrosymmetric sp. gr. P63/m). Mn2+ ions are assembled into tubes along axis c with both NO3- filling and coating. The nitrosonium cation is located in the framework cavity and is disordered by a 3-fold axis. At the temperature TS1 = 190 K, a structural phase transition related to the libration of the intertube NO3 group and a small variation of Mn polyhedron is observed. Moreover, the anomalies in physical properties of (NO)Mn6(NO3)13 allow suggesting that ordering of NO+ units occurs at low temperatures. The antiferromagnetic ordering in this compound is preceded by the formation of a short-range correlation regime at about 25 K and takes place in two steps at TN1 = 12.0 K and TN2 = 8.4 K.

Depressive symptoms among people living with HIV in permanent supportive housing: Findings from a community-based participatory study in Vancouver, Canada.

Permanent supportive housing (PSH) is an intervention addressing housing needs among marginally housed individuals. Little is known about whether and how PSH influences depressive symptoms among people living with HIV (PLHIV). This article shares results from a community-based study that, in 2016-2017, interviewed 24 residents of a PSH facility designated for PLHIV in Vancouver, Canada. The themes of taking control; social connectedness; conviviality; and relationships and supports described how the PSH environment affected depressive symptoms among the residents.

The "Sticky Notes" Method: Adapting Interpretive Description Methodology for Team-Based Qualitative Analysis in Community-Based Participatory Research.

Community-based participatory research (CBPR) has a long history within HIV research, yet little work has focused on facilitating team-based data analysis within CBPR. Our team adapted Thorne's interpretive description (ID) for CBPR analysis, using a color-coded "sticky notes" system to conduct data fragmentation and synthesis. Sticky notes were used to record, visualize, and communicate emerging insights over the course of 11 in-person participatory sessions. Data fragmentation strategies were employed in an iterative four-step process that was reached by consensus. During synthesis, the team created and recreated mind maps of the 969 sticky notes, from which we developed categories and themes through discussion. Flexibility, trust, and discussion were key components that facilitated the evolution of the final process. An interactive, team-based approach was central to data co-creation and capacity building, whereas the "sticky notes" system provided a framework for identifying and sorting data.

Finding the Balance: Embracing the Two-Eyed Seeing Approach to Understand what Cultural Safety in Care Means to Older Adults Living with HIV.

Older adults living with HIV (OALHIV) are a fast-growing demographic who rely on home and community care (HCC) services. Cultural safety (an environment free of racism that fosters feelings of safety and respect) is integral to HCC services. We conducted 27 semi-structured interviews with OALHIV in Vancouver, British Columbia about their HCC experiences. Excerpts about cultural safety were qualitatively analyzed using Two-Eyed Seeing. Our themes-Voices from across Turtle Island, Voices from the African continent, Western Perspectives, and Universal Principles-indicate that cultural safety is important yet lacking. While specific aspects of culturally safe HCC services varied between and within cultural groups, some aspects were shared by participants across groups (e.g., respect, compassion, and non-judgment).

Ising-like Magnetism in Quasi-Two-Dimensional Co(NO3)2·2H2O.

The appearance of electrically neutral water molecules in the structure of cobalt dinitrate dihydrate, Co(NO3)2⋅2H2O, drastically changes its magnetic properties as compared to its waterless counterpart, Co(NO3)2. The title compound shows Ising-like behavior reflected in its thermodynamic properties. It experiences long-range antiferromagnetic order at TN = 20.5 K and metamagnetic transition at µ0HC = 0.76 T. First-principles calculations produce the values of leading exchange interactions J1 ~ 10 K and J2 ~ 0.5 K and single-ion anisotropy D ~ 1 K which allows us to consider Co(NO3)2⋅2H2O as a quasi-two-dimensional magnetic system.

The Importance of Community Consultations for Generating Evidence for Health Reform in Ukraine.

BACKGROUND: The paper presents the results of community consultations about the health needs and healthcare experiences of the population of Ukraine. The objective of community consultations is to engage a community in which a research project is studying, and to gauge feedback, criticism and suggestions. It is designed to seek advice or information from participants directly affected by the study subject of interest. The purpose of this study was to collect first-hand perceptions about daily life, health concerns and experiences with the healthcare system. This study provides policy-makers with additional evidence to ensure that health reforms would include a focus not only on health system changes but also social determinants of health (SDH). METHODS: The data collection consisted of the 21 community consultations conducted in 2012 in eleven regions of Ukraine in a mix of urban and rural settings. The qualitative data was coded in MAXQDA 11 software and thematic analysis was used as a method of summarizing and interpreting the results. RESULTS: The key findings of this study point out the importance of the SDH in the lives of Ukrainians and how the residents of Ukraine perceive that health inequities and premature mortality are shaped by the circumstances of their daily lives, such as: political and economic instability, environmental pollution, low wages, poor diet, insufficient physical activity, and unsatisfactory state of public services. Study participants repeatedly discussed these conditions as the reasons for the perceived health crisis in Ukraine. The dilapidated state of the healthcare system was discussed as well; high out-of-pocket (OOP) payments and lack of trust in doctors appeared as significant barriers in accessing healthcare services. Additionally, the consultations highlighted the economic and health gaps between residents of rural and urban areas, naming rural populations among the most vulnerable social groups in Ukraine. CONCLUSION: The study concludes that any meaningful reforms of the health sector in Ukraine must include a broad range of factors, including the healthcare system but importantly, must extend to SDH approach and include the prioritization of health promotion, limiting alcohol and tobacco availability and enforcing environmental protection.
