Tracking land-use/land-cover change in a watershed of the Cordillera Blanca

Climate change is a global phenomenon with differing regional impacts. One region that stands to be severely affected is the Cordillera Blanca mountain range in northwestern Peru, home to the world’s highest concentration of tropical glaciers. The glaciers in the range have lost 11-30 percent of their area over the last four decades, prompting concern for the region’s future hydrological resources. The flow of the region’s primary river, the Rio Santa, has been found to be declining over the last few decades; one hypothesis is that land-use/land-cover change (LULCC) in the river’s watershed has affected the river’s flow. This thesis examines LULCC in the Rio Santa Watershed region to help contribute social research to the physical research being done in the area. A simple supervised classification was performed on four Landsat satellite images from May/September 1986 and 2006, and the results were compared. The results indicated that wetlands and agricultural areas expanded while forested areas declined; however, methodological and data quality issues impaired the validity of the study’s findings. Future research in the area is needed to provide a holistic view of the region’s systems in order to assist planners and agencies in this dynamic landscape. Advisor: Bryan G. MarkNo embarg

Research priorities for adolescent health in low- and middle-income countries: A mixed-methods synthesis of two separate exercises.

BACKGROUND: In order to clarify priorities and stimulate research in adolescent health in low- and middle-income countries (LMICs), the World Health Organization (WHO) conducted two priority-setting exercises based on the Child Health and Nutrition Research Initiative (CHNRI) methodology related to 1) adolescent sexual and reproductive health and 2) eight areas of adolescent health including communicable diseases prevention and management, injuries and violence, mental health, non-communicable diseases management, nutrition, physical activity, substance use, and health policy. Although the CHNRI methodology has been utilized in over 50 separate research priority setting exercises, none have qualitatively synthesized the ultimate findings across studies. The purpose of this study was to conduct a mixed-method synthesis of two research priority-setting exercises for adolescent health in LMICs based on the CHNRI methodology and to situate the priority questions within the current global health agenda. METHODS: All of the 116 top-ranked questions presented in each exercise were analyzed by two independent reviewers. Word clouds were generated based on keywords from the top-ranked questions. Questions were coded and content analysis was conducted based on type of delivery platform, vulnerable populations, and the Survive, Thrive, and Transform framework from the United Nations Global Strategy for Women's, Children's, and Adolescents' Health, 2016-2030. FINDINGS: Within the 53 top-ranked intervention-related questions that specified a delivery platform, the platforms specified were schools (n = 17), primary care (n = 12), community (n = 11), parenting (n = 6), virtual media (n = 5), and peers (n = 2). Twenty questions specifically focused on vulnerable adolescents, including those living with HIV, tuberculosis, mental illness, or neurodevelopmental disorders; victims of gender-based violence; refugees; young persons who inject drugs; sex workers; slum dwellers; out-of-school youth; and youth in armed conflict. A majority of the top-ranked questions (108/116) aligned with one or a combination of the Survive (n = 39), Thrive (n = 67), and Transform (n = 28) agendas. CONCLUSIONS: This study advances the CHNRI methodology by conducting the first mixed-methods synthesis of multiple research priority-setting exercises by analyzing keywords (using word clouds) and themes (using content analysis)

Exploring the effectiveness of the output-based aid voucher program to increase uptake of gender-based violence recovery services in Kenya: a qualitative evaluation

This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/2.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.Background: Few studies in Africa have explored in detail the ability of output-based aid (OBA) voucher programs to increase access to gender-based violence recovery (GBVR) services. Methods: A qualitative study was conducted in 2010 and involved: (i) in-depth interviews (IDIs) with health managers, service providers, voucher management agency (VMA) managers and (ii) focus group discussions (FGDs) with voucher users, voucher non-users, voucher distributors and opinion leaders drawn from five program sites in Kenya. Results: The findings showed promising prospects for the uptake of OBA GBVR services among target population. However, a number of factors affect the uptake of the services. These include lack of general awareness of the GBVR services vouchers, lack of understanding of the benefit package, immediate financial needs of survivors, as well as stigma and cultural beliefs that undermine reporting of cases or seeking essential medical services. Moreover, accreditation of only hospitals to offer GBVR services undermines access to the services in rural areas. Poor responsiveness from law enforcement agencies and fear of reprisal from perpetrators also undermine treatment options and access to medical services. Low provider knowledge on GBVR services and lack of supplies also affect effective provision and management of GBVR services. Conclusions: The above findings suggest that there is a need to build the capacity of health care providers and police officers, strengthen the community strategy component of the OBA program to promote the GBVR services voucher, and conduct widespread community education programs aimed at prevention, ensuring survivors know how and where to access services and addressing stigma and cultural barriers.The Bill and Melinda Gates Foundatio

Reproductive Health and Bodily Integrity in Tanzania

Several policy initiatives support the empowerment of women to improve their reproductive health. Little is known, however, about the inverse effect that reproductive health might have on women’s empowerment. Women are pressured to conform to their reproductive role, and an inability to do so might affect their empowerment, including control over their own body. This study uses a panel dataset of 504 married women in Northern Tanzania. We find that women who suffered a pregnancy loss show more tolerant views of partner violence (regr. coefficient -0.363; p-value: 0.001), and that child mortality lowers their perceived control over the sexual relationship with their spouse (odds ratio 0.262; p-value: 0.016). The number of children alive did not affect bodily integrity. These results confirm that women’s bodily integrity is partly dependent on the ability to fulfil their reproductive role. They strengthen the case for policies and programmes that improve women’s reproductive health, and underline the importance of counselling after pregnancy or child loss

Prevalence of Parasitaemia, Anaemia and treatment outcomes of Malaria among School Children in a Rural Community in Ghana

A cross-sectional survey was conducted in the Ejisu-Juaben District to determine the prevalence of asymptomatic malaria and anaemia, and treatment outcomes in pupils of seven public schools public schools in a rural community in the forest belt of Ghana. Children with confirmed malaria parasites were randomly assigned to be treated with Artemisinin-based combination therapies available on the Ghanaian market. Post-treatment days 14 and 28 follow-up blood samples were taken to determine the treatment outcomes on peripheral parasitaemia and haemoglobin (Hb) concentrations. Out of 812 pupils (without malaria symptoms) who were screened, the baseline parasitaemia prevalence was 58.6%. Parasitaemia prevalence across the seven (7) public schools ranged from 49.7% to 71.0% (p =0.002). Post-treatment parasitaemia among the different treatment regimes were significant only at day 28 (p<0.001). The mean Hb concentration on the screening day was 10.5g/dl and over 60% of pupils were mildly anaemic (Hb <11.0g/dl) whereas 14% had Hb <8.0g/dl. Post-treatment Hb concentrations of pupils by days 14 and 28 were 11.4g/dl and 11.7g/dl with an improvement of 0.7g/dl and 0.9g/dl respectively over the baseline Hb concentration (p<0.001). The overall proportion of children with Hb concentrations <11.0g/dl was 32.6% and 25.3% by days 14 and 28 respectively. The burden of malaria and anaemia among school children is high and warrants investment to reduce these levels. These findings could be a reflection of the health situation that pertains in the basic public schools especially in the rural forest areas of Ghana.Keywords: asymptomatic malaria, parasitaemia, anaemia, pupils, rural Ghan

Preserved differentiation between physical activity and cognitive performance across young, middle, and older adulthood over 8 years.

Objectives: A critical question in the activity engagement literature is whether physical exercise alters the trajectory of age-related cognitive decline (differential preservation) or is associated with enhanced baseline cognitive ability (preserved differentiation). Further, investigations considering that these relations may differ across young, middle, and older adulthood are rare. Method: We evaluated data from the PATH Through Life Project, where participants aged 20-24, 40-44, and 60-64 years at baseline (n = 6,869) completed physical activity (PA; mild, moderate, and vigorous) and cognitive measurements thrice over 8 years. Results: Multilevel models accounting for employment status, sex, education, health, and mental and social activity showed that between-person differences in PA participation positively predicted baseline performance on fluid cognitive ability (perceptual speed, short-term memory, working memory, and episodic memory). These effects were similar across age groups, but strongest for the youngest cohort, for whom there was also evidence of covariation between within-person change in PA and cognitive score. PA was not associated with change in cognition over time. DISCUSSION: Results support preserved differentiation, where physically active adults have higher initial cognitive ability, and the advantage is maintained over time. PA appears to be unique in showing differences across young, middle, and older adulthood in predicting cognition
