Soil and land health survey to characterize two-100 km2 sites using the Land Degradation Surveillance Framework (LDSF) within Babati district, Tanzania
Contributors: Winowiecki, Leigh
... This was Task 1.2. “Soil survey to characterize two sentinel sites” as part of Work Package 1 “Identification of the key biophysical production constraints to crops and livestock at farm and landscape levels” The aim of this task was to conduct an assessment of soil and land health in the Babati district in Tanzania covering the action villages of the USAID- AfricaRISING project. The Land Degradation Surveillance Framework (LDSF) was employed to conduct a systematic biophysical baseline of key land and soil health metrics, which was to be combined with agronomic survey data collected as part of the wider project. The LDSF is designed to provide a biophysical baseline at landscape level, and a monitoring and evaluation framework for assessing processes of land degradation and the effectiveness of rehabilitation measures (recovery) over time. Babati Agricultural District Office and Tanzania National Agricultural Research System as well as Sokoine University of Agriculture (SUA) staff were involved in two one-week trainings in the LDSF methodology at the Long and Matufa LDSF sites. Those trained include: Majid Suleiman (District Agricultural Officer), Edgar Wakurwa (District Agronomist), Mbwambo (Extension Officer), Prosper Massawe from Selian Agricultural Research Institute and Boniface Massawe, from SUA. George Sayula of SARI also helped coordinate the field efforts. Local farmers were also involved in the surveys and farmer knowledge on management practices and land use history was incorporated into the LDSF database.

... Purpose: Side effects related to radiation exposures are based primarily on the assumption that the detrimental effects of radiation occur in directly irradiated cells. However, several studies have reported over the years of radiation-induced non-targeted/ abscopal effects in vivo that challenge this paradigm. There is evidence that Cyclooxygenase-2 (COX2) plays an important role in modulating non-targeted effects, including DNA damages in vitro and mutagenesis in vivo. While most reports on radiation-induced non-targeted response utilize x-rays, there is little information available for heavy ions. Methods and Materials: Adult female transgenic gpt delta mice were exposed to an equitoxic dose of either carbon or argon particles using the Heavy Ion Medical Accelerator in Chiba (HIMAC) at the National Institute of Radiological Sciences (NIRS) in Japan. The mice were stratified into 4 groups of 5 animals each: Control; animals irradiated under full shielding (Sham-irradiated); animals receiving whole body irradiation (WBIR); and animals receiving partial body irradiation (PBIR) to the lower abdomen with a 1 x 1 cm2 field. The doses used in the carbon ion group (4.5 Gy) and in argon particle group (1.5 Gy) have a relative biological effectiveness equivalent to a 5 Gy dose of x-rays. 24 hours after irradiation, breast tissues in and out of the irradiated field were harvested for analysis. Induction of COX2, 8-hydroxydeoxyguanosine (8-OHdG), phosphorylated histone H2AX (γ-H2AX), and apoptosis-related cysteine protease-3 (Caspase-3) antibodies were examined in the four categories of breast tissues using immunohistochemical techniques. Analysis was performed by measuring the intensity of more than 20 individual microscopic fields and comparing the relative fold difference. Results: In the carbon ion group, the relative fold increase in COX2 expression was 1.01 in sham-irradiated group (p > 0.05), 3.07 in PBIR (p 0.05), 11.31 in PBIR (p 0.05), 8.41 in PBIR (p < 0.05) and 10.59 in WBIR (p < 0.05). Results for the argon particle therapy group showed a similar magnitude of changes in the various biological endpoints examined. There was no statistical significance observed in Caspase-3 expression among the 4 groups. Conclusions: Our data show that both carbon and argon ions induced non-targeted, out of field induction of COX2 and DNA damages in breast tissues. These effects may pose new challenges to evaluate the risks associated with radiation exposure and understanding radiation-induced side effects.
Vietnam (2013): TRaC behavioral survey among female sex workers and female sex workers who inject drugs in 7 provinces of Vietnam. Round 3.
Contributors: Chi, Le Thi Linh, Neukom, Josselyn
... The 2012 SW & SW-IDU Behavioral Survey is the third and final round of this survey conducted by the USAID Social Marketing for HIV Prevention Project with USAID/PEPFAR support. Research objectives include to monitor changes in risk reduction behaviors and factors associated with key behavioral indicators over time, as outlined in PMEP, to evaluate correlation between project coverage and changes in key PMEP behavioral and determinant indicators, to provide data/evidence to support the Low Dead S pace (LDS) syringe SM pilot, and to inform total market approach programming. Study respondents were recruited through RDS to facilitate reach of hidden SWs. A structured questionnaire was used, estimated to take 30-45 minutes to complete for each participant
Madagascar (2009): FoQus on Marketing Planning - Developing a positioning statement for Protector Plus
Contributors: PSI Research
... Designing the concept for a social marketing activity requires familiarity with the target audience and the context in which behavior change takes place. This study aims to gather data useful for designing the following eight elements of the concept for Protector Plus aimed at Malagasy men 25-44 years old, users and non users of Protector Plus. Photo narratives will be used to collect data for its ease of use and the richness of data produced when photos accompany narratives This study will be conducted in all Tana among different categories of men aged 25 - 44.

... The goal of this study is to monitor provider FP recommending practices to assess the effectiveness of the provider training and detailing activities. PSI/Nepal utilized mystery client survey technique to gather information from the network providers. This technique allowed PSI to determine the quality of service offered to clients. The purpose of this study is to establish a baseline for the next phase of the program and to provide monitoring information regarding network provider FP recommending practices and counseling behavior.
Vietnam (2013): Health seeking behaviors and Tuberculosis (TB) knowledge among people with TB symptoms
Contributors: Josselyn Neukom, Bui Hong Son
... In early 2013, PSI conducted a study to assess TB knowledge and health seeking behaviors among individuals with TB symptoms in 2 of the 3 project provinces. The study was designed to achieve the following objectives: (1) Understand health seeking behaviors in general, and related to TB, (2) Assess knowledge levels about TB among individuals at risk, (3) Identify motivations and barriers to seeking TB diagnosis/treatment among individuals at risk, and (4) Assess exposure to TB communications and associations between exposure to social marketing campaign and improved TB knowledge/health seeking behavior. The survey was conducted after approximately 6-9 months of program implementation in the two provinces.
