Green Chemistry Teacher Professional Development in New York State High Schools: A Model for Advancing Green Chemistry.

Teaching green chemistry within the K-12 classroom has a positive impact on attitudes and perceptions of chemistry in society for future scientists and professionals, resulting in safer, less hazardous chemistry experiments and demonstrations. The state of New York has taken advantage of the benefits that green chemistry provide in the classroom and is a leader in professional development for high school teachers throughout the state. Between 2011 and 2016, Beyond Benign and Siena College implemented 14 workshops across the state as part of New York's Department of Environmental Conservation goal of reducing hazardous chemicals in schools. At these workshops, 224 teachers were introduced to green chemistry principles and practices and provided resources for replacing traditional laboratory experiments with alternatives that used safer materials. Two professional development models were implemented, a one-day introductory workshop and a three-day train-the-trainer style in-depth workshop, using collaborative, hands-on, intensive, and peer-learning techniques. In response to a 2021 follow-up survey, participants shared that they continue to use skills from the professional development they received and reported sharing about green chemistry with peers, parents, and administrators. The long-term engagement of the participants indicates that successful models were implemented to provide a path to develop teacher leaders. Professional development models are presented herein for sharing best practices and approaches for training high school teachers on green chemistry, providing numerous benefits to both teachers and students in high school classrooms.

Essential newborn care practice at four primary health facilities in conflict affected areas of Bossaso, Somalia: a cross-sectional study.

BACKGROUND: Newborn mortality is increasingly concentrated in contexts of conflict and political instability. However, there are limited guidelines and data on the availability and quality of newborn care in conflict settings. In 2016, an interagency collaboration developed the Newborn Health in Humanitarian Settings Field Guide- Interim version (Field Guide). In this study, we sought to understand the baseline availability and quality of essential newborn care in Bossaso, Somalia as part of an investigation to determine the feasibility and effectiveness of the Field Guide in improving newborn care in humanitarian settings. METHODS: A cross-sectional study was conducted at four purposely selected health facilities serving internally displaced persons affected by conflict in Bossaso. Essential newborn care practice and patient experience with childbirth care received at the facilities were assessed via observation of clinical practice during childbirth and the immediate postnatal period, and through postnatal interviews of mothers. Descriptive statistics and logistic regression were employed to summarize and examine variation by health facility. RESULTS: Of the 332 pregnant women approached, 253 (76.2%) consented and were enrolled. 97.2% (95% CI: 94.4, 98.9) had livebirths and 2.8% (95% CI: 1.1, 5.6) had stillbirths. The early newborn mortality was 1.7% (95% CI: 0.3, 4.8). Nearly all [95.7%, (95% CI: 92.4, 97.8)] births were attended by skilled health worker. Similarly, 98.0% (95% CI: 95.3, 99.3) of newborns received immediate drying, and 99.2% (95% CI: 97.1, 99.9) had delayed bathing. Few [8.6%, (95% CI: 5.4, 12.9)] received immediate skin-to-skin contact and the practice varied significantly by facility (p < 0.001). One-third of newborns [30.1%, (95% CI: 24.4, 36.2)] received early initiation of breastfeeding and there was significant variation by facility (p < 0.001). While almost all [99.2%, (95% CI: 97.2, 100)] service providers wore gloves while attending births, handwashing was not as common [20.2%, (95% CI: 15.4, 25.6)] and varied by facility (p < 0.001). Nearly all [92%, (95% CI: 86.9, 95.5)] mothers were either very happy or happy with the childbirth care received at the facility. CONCLUSION: Essential newborn care interventions were not universally available. Quality of care varied by health facility and type of intervention. Training and supervision using the Field Guide could improve newborn outcomes.

Uptake of postabortion care services and acceptance of postabortion contraception in Puntland, Somalia.

Unsafe abortion is responsible for at least 9% of all maternal deaths worldwide; however, in humanitarian emergencies where health systems are weak and reproductive health services are often unavailable or disrupted, this figure is higher. In Puntland, Somalia, Save the Children International (SCI) implemented postabortion care (PAC) services to address the issue of high maternal morbidity and mortality due to unsafe abortion. Abortion is explicitly permitted by Somali law to save the life of a woman, but remains a sensitive topic due to religious and social conservatism that exists in the region. Using a multipronged approach focusing on capacity building, assurance of supplies and infrastructure, and community collaboration and mobilisation, the demand for PAC services increased as did the proportion of women who adopted a method of family planning post-abortion. From January 2013 to December 2015, a total of 1111 clients received PAC services at the four SCI-supported health facilities. The number of PAC clients increased from a monthly average of 20 in 2013 to 38 in 2015. During the same period, 98% (1090) of PAC clients were counselled for postabortion contraception, of which 955 (88%) accepted a contraceptive method before leaving the facility, with 30% opting for long-acting reversible contraception. These results show that comprehensive PAC services can be implemented in politically unstable, culturally conservative settings where abortion and modern contraception are sensitive and stigmatised matters among communities, health workers, and policy makers. However, like all humanitarian settings, large unmet needs exist for PAC services in Somalia.

Twelve-month contraceptive continuation among women initiating short- and long-acting reversible contraceptives in North Kivu, Democratic Republic of the Congo.

CONTEXT: Despite the inclusion of sexual and reproductive health (SRH) services in the minimum standards of health care in humanitarian settings, access to SRH services, and especially to contraception, is often compromised in war. Very little is known about continuation and switching of contraceptive methods in these settings. An evaluation of a contraceptive services program in North Kivu, Democratic Republic of the Congo (DRC) was conducted to measure 12-month contraceptive continuation by type of contraceptive method (short-acting or long-acting). METHODS: A stratified systematic sample of women who initiated a contraceptive method 12-18 months prior to data collection was selected retrospectively from facility registers. A total of 548 women was interviewed about their contraceptive use: 304 who began a short-acting method (pills, injectables) and 244 who began a long-acting method (intra-uterine devices, implants). Key characteristics of short-acting method versus long-acting method acceptors were compared using chi-square statistics for categorical data and t-tests for continuous data. Unadjusted and adjusted Cox proportional hazard ratios were estimated to assess factors associated with discontinuation. RESULTS: At 12 months, 81.6% women reported using their baseline contraceptive method continuously, with more long-acting than short-acting contraceptive acceptors (86.1% versus 78.0%, p = .02) continuing contraceptive use. Use of a short-acting method (Hazard ratio (HR) 1.74 [95%CI 1.13-2.67]) and desiring a child within two years (HR 2.58 [95%CI 1.45-4.54]) were associated with discontinuation within the first 12 months of use. The vast majority (88.3%) of women reported no prior contraceptive use. CONCLUSION: This is the first study of contraceptive continuation in a humanitarian setting. The high percentages of women continuing contraceptive use found here demonstrates that women will choose to initiate and continue use of their desired contraceptive method, even in a difficult, unstable and low contraceptive prevalence setting like North Kivu.

The science of green chemistry and its role in chemicals policy and educational reform.

Over the past 10 years, the science of green chemistry has continued to evolve and has been adopted in research labs in industry and academia. At the same time, new innovations in chemicals policy have widened opportunities for legislative action to protect human health and the environment. This article addresses the mechanisms by which the science of green chemistry and chemicals policy can work together to help attain a more sustainable future. It also speaks to the pitfalls of inappropriately merging these two, and explores how such a merger could inhibit the creation of sustainable technologies. Green chemistry's role in educational reform is discussed as a means for training students who are prepared to create truly sustainable technologies.

Effect of pH on the viscosity of titanium dioxide aqueous dispersions with carboxylic acids.

Dispersions of titanium dioxide nanoparticles with terephthalic acid, isophthalic acid, salicylic acid, benzoic acid, and pyridine-2,5-dicarboxylic acid were prepared by aqueous grinding. The pH of the dispersions was adjusted by adding either HCl or NaOH, and the viscosity of the dispersions was measured. It was found that the viscosity of the system depends strongly on pH. The qualitative interpretation of the results based on the DLVO theory is presented. The evidence of the effect of bridging interactions on the viscosity of titanium dioxide-dicarboxylic acid dispersions is discussed.
