Abstract:
La France est le pays industrialisé le plus touché par le paludisme d’importation avec environ 4735 de cas importés et répertoriés en 2016. Les voyageurs migrants, originaires des pays où sévit le paludisme et résidant en France, représentent 82,2 % des cas d’infections palustres. Cette thèse cherche principalement à analyser la question du recours à la prévention du risque palustre auprès des voyageurs migrants originaires des pays d’Afrique Subsaharienne de Bordeaux. À partir d’observations directes et d’entretiens individuels avec différents acteurs, cette recherche montre une hétérogénéité des situations d’exposition au risque palustre lors du retour temporaire au pays d’origine. Ce risque dépend des situations expérientielles, et socio-économiques, ainsi que des charges qu’il est supposé y assumer. Lorsque ces charges sont importantes, le voyageur migrant a tendance à hiérarchiser les risques, avec une non-priorisation du palustre au profit du risque de « toubabisation », socialement moins accepté. La non-priorisation du risque de paludisme est accentuée par une perception banalisante, ordinaire et quotidienne du paludisme en contexte de migration et par le non-remboursement de la chimioprophylaxie par la Caisse Nationale Assurance Maladie. Ce travail montre que le non recours à la chimioprophylaxie est influencé par l’absence d’expérience du paludisme en France et de paludisme grave dans le pays d’origine. Souvent, il faut que l’expérience de cette maladie soit vécue et perçue dans le pays d’accueil pour qu’elle induise un changement de perception et donc, un recours futur à la prévention. Sur le plan thérapeutique, cette thèse met en évidence des retards de diagnostic du paludisme en médecine générale. Ces retards sont causés par l’absence d’association de la « fièvre du retour » et des symptômes associés à un accès palustre, et par son « exotisme » en France. À ce titre, cette recherche apporte une contribution aux réflexions dans les champs de l’anthropologie de la santé et de l’anthropologie du risque lié au voyage avec comme exemple les voyageurs migrants exposés au risque palustre<br>France is the industrialized country most assigned by import malaria with around 4735 imported and registered cases in 2016. Migrant travelers from malaria-affected countries residing in France account for 82.2% of all malaria cases. malaria infections. This thesis mainly seeks to analyze the issue of the use of malaria risk prevention among migrant travelers from sub-Saharan African countries in Bordeaux. Based on direct observations and individual interviews with different actors, this research shows the heterogeneity of situations of exposure to malaria risk during temporary return to the country of origin. This risk depends on the experiential and socio-economic situations, as well as the burdens it is supposed to assume. When these burdens are significant, the migrant traveler tends to prioritize the risks, with a non-prioritization of malaria control in favor of the risk of “toubabisation”, socially less accepted. The non-prioritization of the risk of malaria is accentuated by a banal, ordinary and daily perception of malaria in the context of migration and by the non-reimbursement of chemoprophylaxis by the National Health Insurance Fund. This work shows that the non-use of chemoprophylaxis is influenced by the lack of experience of malaria in France and severe malaria in the country of origin. Often, the experience of this disease must be experienced and perceived in the host country to induce a change of perception and therefore a future use of prevention. Therapeutically, this thesis highlights delayed diagnosis of malaria in general practice. These delays are caused by the lack of association of the “return fever” and symptoms associated with malaria, and by its “exoticism” in France. As such, this research contributes to reflections in the fields of anthropology of health and anthropology of travel risk, with the example of migrant travelers exposed to malaria risk

Full text
Abstract:
Drug-induced acute tubulointerstitial nephritis (ATIN) is the most common aetiology of ATIN and a potentially correctable cause of acute kidney injury (AKI). An interval of 7–10 days typically exists between drug exposure and development of AKI, but this interval can be considerably shorter following re-challenge or markedly longer with certain drugs. It occurs in an idiosyncratic and non-dose-dependent manner. Antibiotics, NSAIDs, and proton pump inhibitors are the most frequently involved agents, but the list of drugs that can induce ATIN is continuously increasing. The mechanism of renal injury is postulated to involve cell-mediated immunity, supported by the observation that T cells are the predominant cell type comprising the interstitial infiltrate. A humoral response underlies rare cases of ATIN, in which a portion of a drug molecule (i.e. methicillin) may act as a hapten, bind to the tubular basement membrane (TBM), and elicit anti-TBM antibodies. The classic symptoms of fever, rash, and arthralgia may be absent in up to two-thirds of patients. Diagnostic studies, such as urine eosinophils and renal gallium-67 scanning provide only suggestive evidence. Renal biopsy remains the gold standard for diagnosis, but it may not be required in mild cases or when clinical improvement is rapid after removal of an offending medication. Pathologic findings include interstitial inflammation, oedema, and tubulitis. The time until removal of such agents and the severity of renal biopsy findings provide the best prognostic value for the return to baseline renal function. Poor prognostic indicators are the long duration of AKI (&gt; 3 weeks), a patient’s advanced age, and the high degree of interstitial fibrosis. Early recognition and appropriate therapy are essential to the management of drug-induced ATIN, because patients can ultimately develop chronic kidney disease. The mainstay of therapy is timely discontinuation of the causative agent, whereas controversy persists about the role of steroids.

Abstract:
Asylum-seekers are those who have applied for international protection. Asylum status is still governed by the 1951 United Nations Convention relating to the Status of Refugees. ‘Refugees and asylum-seekers’ explains the changing geography of refugees and the causes and consequences of refugee movements. Refugees tend not to travel very far, putting strain on the poorest countries, and mostly settle in camps, which suffer from aid misappropriation. There are three durable solutions for refugees: voluntary repatriation, local integration, and third-country settlement. Each can be problematic and none is working well at the moment, as demonstrated by rising numbers of refugees, the increasing proportion of protracted refugee situations, and fewer returns.

Abstract:
Bacteria of the genus Rickettsia belong to the family Rickettsiaceae in the order Rickettsiales and have for long been described simply as short, Gram-negative, strict intracellular rods that retain basic fuchsin when stained by the method of Gimenez (Raoult and Roux 1997). These bacteria are associated with ticks, lice, fleas or mites. To date the Rickettsia genus contains 24 recognized species classified into three groups based on their antigenic, morphological, and ecologic patterns: 1) the typhus group, 2) the spotted fever group and 3) Rickettsia bellii (Fournier and Raoult 2007). Most spotted fever group (SFG) rickettsiae are closely associated with ticks belonging to the family Ixodidae (also called “hard” ticks) (Parola et al. 2005). Ticks can act as vectors, reservoirs, and/or amplifiers of SFG rickettsiae and require optimal environmental conditions which determine the geographic distribution of the vectors and consequently the risk areas for rickettsioses. Many Rickettsia species are strictly associated with one genus of ticks and the transmittion to people is made through the tick bite, which generally implies that the Rickettsia can localize to their salivary glands. Therefore, since larvae, nymphs, and adults may all be infective for susceptible vertebrate hosts, the ticks must be regarded as the main reservoir host of rickettsiae. Humans are not considered as good reservoirs for Rickettsiae, as they are seldom infested with ticks for long periods and rickettsiaemia has normally short duration, especially with antibiotic intervention.

Abstract:
American higher education is at a crossroads. Technological innovations and disruptive market forces are buffeting colleges and universities at the very time their financial structure grows increasingly fragile. Disinvestment by states has driven up tuition prices at public colleges, and student debt has reached a startling record-high of one trillion dollars. Cost-minded students and their families--and the public at large--are questioning the worth of a college education, even as study after study shows how important it is to economic and social mobility. And as elite institutions trim financial aid and change other business practices in search of more sustainable business models, racial and economic stratification in American higher education is only growing. In American Higher Education in Crisis?: What Everyone Needs to Know, Goldie Blumenstyk, who has been reporting on higher education trends for 25 years, guides readers through the forces and trends that have brought the education system to this point, and highlights some of the ways they will reshape America's colleges in the years to come. Blumenstyk hones in on debates over the value of post-secondary education, problems of affordability, and concerns about the growing economic divide. Fewer and fewer people can afford the constantly increasing tuition price of college, Blumenstyk shows, and yet college graduates in the United States now earn on average twice as much as those with only a high-school education. She also discusses faculty tenure and growing administrative bureaucracies on campuses; considers new demands for accountability such as those reflected in the U.S. Department of Education's College Scorecard; and questions how the money chase in big-time college athletics, revelations about colleges falsifying rankings data, and corporate-style presidential salaries have soured public perception. Higher education is facing a serious set of challenges, but solutions have also begun to emerge. Blumenstyk highlights how institutions are responding to the rise of alternative-educational opportunities and the new academic and business models that are appearing, and considers how the Obama administration and public organizations are working to address questions of affordability, diversity, and academic integrity. She addresses some of the advances in technology colleges are employing to attract and retain students; outlines emerging competency-based programs that are reshaping conceptions of a college degree, and offers readers a look at promising innovations that could alter the higher education landscape in the near future. An extremely timely and focused look at this embattled and evolving arena, this primer emphasizes how open-ended the conversation about higher education's future remains, and illuminates how big the stakes are for students, colleges, and the nation.

AbstractThis case addresses the challenge of leadership succession in a highly respected master’s program at a university in Australia. The director, who was also the program’s lead professor, was due to retire, and the distinctive nature of the program made it particularly difficult to find a suitable replacement. To complicate the challenge, the university’s central administration was not supportive of that master’s degree, whereas it achieved the highest satisfaction ratings in the university from students and enjoyed good support from industry; the director’s insistence on quality of educational experience resulted in tight control of student admission, fewer students, and lower revenue than competing programs.A highly engaged group of students and alumni took on this challenge, working with the outgoing director to sustain impressive results over a 5-year period.

Abstract:
Travel-related problems have been reported in up to two-thirds of travellers to developing countries and approximately 10% of them seek medical advice during or after return from abroad. Furthermore, global migration from the developing to the developed world has increased over the past decades and these individuals may present with tropical infections soon after arrival in non-endemic settings. Fever, with or without localizing symptoms or signs, is a common presenting symptom in returning travellers. Most unwell travellers seek medical attention within one month of return from abroad. Travellers who visit friends and relatives (VFRs) in their countries of origin are disproportionately affected by the burden of imported infections, e.g. 70% of patients with imported malaria in the United Kingdom (UK) are VFRs. While most febrile travellers have common infections such as respiratory or urinary tract infection, it is of paramount importance not to miss potentially life-threatening tropical infections. Evaluation of fever in returning travellers requires an understanding of the geographical distribution of infectious diseases, risk factors for acquisition, incubation periods, and major clinical syndromes of travel-associated infections. The following points should be considered when assessing febrile international travellers: A. Travel dates: the relationship between the timing of the onset of symptoms and travel dates should be assessed. B. Geography: ● travel destination: a detailed itinerary is required. ● local setting: urban vs rural locations; type of accommodation, e.g. air-conditioned hotel room, outdoor camping, etc. C. Risk factors for acquiring infectious diseases: ● purpose of travel: visiting friends and family; social gatherings (e.g. funerals and weddings); mass gatherings (e.g. Hajj pilgrimage, Kumbh Mela religious festival, Olympic games, etc.); tourism; business; voluntary work. ● contact with unwell individuals. ● activities while abroad (examples): ■ food consumption: street food, seafood, raw food, unpasteurized dairy products, exotic foods, bush meat, etc. ■ contact with animals: visits to game parks, farms, caves, bites or scratches by bats or terrestrial animals, visits to ‘wet markets’, birding events, etc. ■ bites: ticks, insects, snakes, spiders, etc. ■ use of local healthcare system: dental or surgical procedures, blood transfusion, dialysis, tattoos, acupuncture.

Abstract:
By 1927, Crystal Eastman had been living as the freelance journalist she never wanted to be, pitching article after article to conservative or capricious editors. She had recently covered the momentous International Woman Suffrage Alliance congress in Paris, but was generally exhausted from childcare and homemaking, frustrated by declining health, and almost always behind in her bills. She longed to return to home. Paul Kellogg advised patient planning and supplied a prescient idea for new line of work, but she returned to New York quite hastily, with only a short speaking engagement planned. Three weeks later, Walter died of a cerebral hemorrhage. Deep in mourning, Eastman began a temporary job organizing a celebration for The Nation. Her colleagues noticed she was fighting a tremendous battle. In fact, she was mortally ill. Her kidneys, damaged long ago by scarlet fever, were now giving out. Ten months later, she passed away.

Abstract:
The chapter describes Venizelos's activities after his return to Crete from Athens in 1889. Family affairs were important, starting with marriage to Maria in December 1890, followed by the birth of Kyriakos (1892) and Sophocles (1894). Maria died of puerperal fever after the birth of Sophocles. Venizelos took this hard, his friends reporting his excessive display of grief, and statement that he would never marry again. This was a time of family concerns but also of legal work. He argued for exerting pressure on the Ottomans for reconvening the Assembly, but acting always within the law. In his legal practice he took on unpopular cases where necessary, and was quick to defend his honor when it was attacked. Meanwhile he extended his range of friends, mainly among liberals, and including the consuls general of the Powers, in which his improving English and French and skill at bridge paid off. He made clear e.g. to the journalist Dimitrios Kaklamanos his belief that Crete must adapt to circumstances and to the policies of the Powers.

Abstract:
A new method is introduced for combining the long-term distribution of sea states with the short-term distribution of individual wave or crest heights, conditional on sea state. The method uses a Monte Carlo approach to simulate random realisations of the maximum wave or crest height in each sea state. A peaks-over-threshold analysis is conducted on the random maxima in each sea state in order to estimate the long-term distribution of individual wave or crest heights. The new method is significantly simpler than existing methods such as the equivalent storm approach, requires fewer assumptions and has similar computational times. The new method is applied to a 35 year dataset of wave buoy measurements and is shown to produce almost identical estimates of return values of individual crest heights to the equivalent storm method.

Abstract:
Maintenance, especially in a Marine environment, is continuous and costly. Life Cycle Management of a Marine Gas Turbine system encompasses many costs, of which repair parts, labor and equipment downtime associated with failures and maintenance are a significant portion. In fact, people (labor) make up the largest component of overall maintenance costs. Investing in people the largest cost driver to life cycle cost has a direct return in the long run, in terms of maintenance effectiveness and efficiencies. Applying and reinforcing knowledge and skills in a maintenance environment translates to improved reliability outcomes, longer operating time, fewer parts needs, and ultimately costs savings. However, given today’s constrained fiscal environment, the value of spending money for training rather than buying more parts or applying more maintenance, may not appear obvious. Such thinking is short sighted, and ultimately leads to reduced reliability and increased maintenance in the long run. This paper will explore these areas, and recommend how training programs can be effective predictive, proactive and responsive.

Abstract The paper describes the design and status of development of a new open volumetric air receiver prototype. This receiver design, though developed in two phases, constitutes one deliverable in a Spanish project carried out by CIEMAT, IAER and INABENSA. The project, called SIREC, is partially financed by the European Funds for the Regional Development program (FEDER). The receiver prototype is now in fabrication and will be tested in the Sulzer volumetric receiver test facility at the Plataforma Solar de Almería (PSA) in Spain. Testing is scheduled for April, 2001. The prototype design includes an air return system and modular absorber elements, to facilitate their replacement and reduce manufacturing costs. The absorber is wire mesh. A computer code has been set up to select the mesh size (wire diameter and mesh distance) and number of screens. A sensitivity analysis for a variety of operating conditions has been carried out with this code to guide the absorber design and its testing.

Full text
Abstract:
Abstract A review of the utilization of Drilling Equipment highlighted an opportunity to lower operational cost for the Operator, reduce Capital Employed for the Service Company, and reduce industry Scope 1 CO2 emissions. The Operator and the Oilfield Services Company set the objective of developing a risk-based probability model that could be used to assess the positive and negative financial impacts of reducing, or perhaps entirely removing, the need for backup drilling tools in the historically risk-averse UK North Sea. The scope of the analysis was to be a drilling campaign on a single rig contracted by the Operator (Rig A). The last three years of Drilling tool reliability data from North Sea operations, as recorded by the Drilling Service Provider, were used as an input. To assess the probability of failure, a Binomial Model was developed to create a Binomial Distribution for each tool, before determining the probability of failure of a given drilling string. The method calculates the probability of having 0 to X failures for a selected Drilling tool/string for a given number of runs. Three Binomial Models were developed to analyze the effect of "Easy", "Moderate" and "Challenging" drilling environments on drilling tool reliability. A financial risk model was developed that balanced the probability-weighted cost of failure for the Operator against the lower costs resulting from reduced tool provision by the Service Provider. In order to better estimate the risks and financial impacts on the project, Sensitivity Analysis was performed on the financial risk model using the three Binomial Models. Scope 1 CO2 emission reductions result from fewer logistical movements and diminished backup tool manufacturing requirements. As a result of the analysis, it was shown that recent improvements in tool reliability support a reduction in backup Drilling tools for the majority of North Sea drilling scenarios, meeting the objective of reducing well construction cost while lowering carbon footprint. Open discussions, focused on maximizing economic hydrocarbon recovery, reducing costs for the Operator, improving Return on Capital Employed for the Oilfield Services Provider and reducing Scope 1 CO2 emissions, resulted in a commercial model that could deliver a Win-Win scenario for all parties. It was observed that the approach was scalable, and would deliver further benefit from a broader workscope, generating "network" benefits when applied to a cluster of rigs, and/or an entire play/basin. In addition, the risk model can be applied to alternative industry scenarios where strong reliability data exist.

Abstract:
Background: Driving is a complex day-to-day activity that employs a variety of cognitive and psychomotor functions in harmony, many of which are known to be affected acutely by CNB intoxication which could in turn pose a significant public health risk. The recent legalization of both recreational and/or medicinal marijuana in several states has thus created an urgent need to better understand the effects of CNB on such functions in the context of driving. The present study employs a longitudinal, double-blind, placebo- 2 active dose study to investigate the effects of CNB on a variety of driving-related behaviors in a controlled, naturalistic simulated environment. Methods: The current study employed N=37 subjects (N=25 male, frequent cannabis users, mean age 24.25+7.01), each exposed to a placebo, low and high dose of CNB on three separate days. On each day, following a single acute inhaled 0.5 g dose of either 0%, 3% or 5-7% of THC via a desktop vaporizer, subjects drove a virtual driving simulator (RTI SimVehicle platform) three times inside an MRI scanner and once out of scanner, randomized, and dispersed throughout an eight hour daily period. During each driving session three distinct real time behavioral tasks corresponding to lane-keeping following simulated wind gusts (operational), lead car following (tactical) and safe overtaking (strategic) were assessed and corresponding behavioral data were computed using custom Matlab scripts. Data were analyzed using a mixed model framework in SPSS v24 which included dose, session, instrument (desktop v MRI), dose*session, dose*instrument and session*instrument as primary factors, covarying for age and sex. Results: Intoxicated subjects made significantly fewer gas pedal corrections (p&lt;0.02) during the car following task and similarly fewer corrections to the steering reversal rate (p&lt;0.02) during the lane weaving task, suggesting reduced awareness under the influence of cannabis. In addition we found that several variables showed significant differences in terms of estimates captured throughout the day suggesting that overall risk taking lessened as the day progressed and CNB effects wore off. Also, data trends suggested that under the high dose subjects took longer to return to baseline from their ‘impaired’ driving patterns. Key metrics that showed such significant daily effects included mean headway (p&lt;0.001) and time to collision (p=0.02) from the car following task, deviation of lane position (p=0.03) from the lane weaving task, median gap (p=0.02) and overtaking speed (p=0.02) from the overtaking task. Although many driving measurements differed depending on whether driving was done in MRI or at a desktop setting, these differences had no relationship to different drug dose levels. Conclusion: In summary, key driving functions affected under higher doses of CNB largely agreed current cross sectional literature. Generally, largest impairments in driving behavior seemed to occur within 1-4 hours after drug exposure, which might have important implications for real life driving situations. Our preliminary analyses yield numerous metrics that changed throughout the day, suggesting broad-based impairment on many metrics commonly used to quantify driving performance and risk.

Abstract:
Wireless handheld communications has identified significant benefits of tuning that include fewer dropped calls, increased battery life and improved user experience. The tuning can be part of the antenna, power amplifier (PA), filtering, or part of a fully integrated radio front end (FE). RF MEMS tunable capacitors have been integrated with 0.18 μm RF HVCMOS to address the need for tuning in wireless communications. These integrated, MEMS tunable capacitors are hermetically encapsulated at the wafer level, but the integrity of the encapsulation must be maintained during BEOL operations. The BEOL operations include shipping and handling, passivation coat and cure, solder bumping (screen printed or electroplated), backside grinding (BSG), dicing, and pick and place. In this paper we will describe, the flip chip packaging of the wafer level encapsulated MEMS devices including finite element analysis. The flip chip packaging of ASIC die is primarily concerned with solder bump reliability during such qualification stresses as temperature cycling and drop testing. The flip chip packaging of a wafer level encapsulated MEMS device has additional concerns that include encapsulation integrity and device package sensitivity. The die thickness, underfill, and encapsulation dimension have been varied to minimize the deflection and stress associated with the encapsulation. The primary failure mode associated with the overstress of the encapsulation is a cracked lid that will lead to the ingress of moisture and a rise in the cavity pressure from to atmospheric conditions. The failure can be detected by an increase in the MEMS switching time and frequency response or by a return to zero failure (RTZ) associated with device stiction. A low modulus and low CTE UF has been implemented for the lowest deflection and stress. The lowest deflection and stress is provided by eliminating the UF, but this is not feasible for the purpose of solder bump reliability. In practice, the MEMS encapsulation is robust to the printed solder bumping process that includes placement and removal of the bump screen and the squeegee of solder past into the solder screen. The MEMS encapsulation is robust to the attachment and removal of BSG tape and the pressures associated with BSG. The final dicing operation has not demonstrated any detrimental impact on the MEMS encapsulation. The final demonstration of success is the assembly of the MEMS tunable capacitor die to a laminate substrate using lead-free solder and underfill.

Abstract:
Increasingly stringent regulations on emissions in the gas turbine industry require novel designs to minimize the environmental impact of oxides of nitrogen (NOx). The development of advanced low-NOx technologies depends on accurate and reliable thermochemical mechanisms to achieve emissions targets. However, current combustion models have high levels of uncertainty in kinetic rates that, when propagated through calculations, yield significant variations in predictions. A recent study identified and optimized nine elementary reactions involved in CH formation to accurately capture its concentration and improve prompt-NO predictions. The current work quantifies the uncertainty on peak CH concentration and NOx emissions generated by these nine reaction rates only, when propagated through the San Diego mechanism. Various non-intrusive spectral methods are used to study atmospheric alkane-air flames. 1st- and 2nd-order total-order expansions and tensor-product expansions are compared against a reference Monte Carlo analysis to assess the ability of the different techniques to accurately quantify the effect of uncertainties on the quantities of interest. Sparse grids, subsets of the full tensor-product expansion, are shown to retain the advantages of tensor formulation compared to total-order expansions while requiring significantly fewer collocation points to develop a surrogate model. The high resolution per dimension can capture complex probability distributions witnessed in radical species concentrations. The uncertainty analysis of lean to rich flames demonstrated a high variability in NOx predictions reaching up to 400 % of nominal predictions. Wider concentration intervals were observed in rich conditions where prompt-NOx is the dominant contributor to emissions. The high variability and scale of uncertainty in NOx emissions originating from these nine elementary reactions demonstrate the need for future experiments and data assimilation to constrain current models to accurately capture CH for robust NOx emissions predictions.

Abstract:
A prosthetic limb is an artificial device that replaces missing body part, or parts. Prosthetic limbs are used for many different applications however the application of prosthetic limbs focused in this paper categorized as prosthetic enhancements. Prosthetic enhancements are special prosthetic that allow the patients to participate in more rigorous recreational activities, such as running. These prosthetic limbs now have started to arise in major sporting events like the Olympics. Some researchers say that the legs use only 25% of the energy that an able bodied leg would use. High performance prosthetic running legs made of carbon fiber, show great advantages over their metal counterparts. Including being lighter and being able to retain more strain energy, current carbon fiber running blades offered by Ossur provide the best performance in the market. In this study, prosthetic racing legs known as blades were analyzed using finite element analysis technique. Performance improvements of these blades were sought by creating mechanical models of the current Ossur products using the finite element analysis software ANSYS and incorporating better performing composite materials into the mechanical simulations. Two different composite materials have taken in consideration by which the legs are created from, these are thermoplastic values for polyethylene epoxy and Vinylester. The use of a new composite material reduces the strain in each of the existing blade geometries, and it permits fewer layers of carbon fiber to be required in the construction of these running blades, which reduces the weight of each leg. Three different blade designs such as Cheetah blade, Flex-Run blade and Flex-Sprint blade have been considered in this study. Also two different loading conditions on the blade such as standing and running conditions have been considered.

Abstract:
In this Insight Note, we report results of a phone survey that the RISE Tanzania Research team conducted with 2,240 parents (or alternate primary care-givers) of primary school children following the school closures in Tanzania. After the first case of COVID-19 was confirmed in Tanzania on 16 March 2020, the government ordered all primary schools closed the following day. Schools remained closed until 29 June 2020. Policymakers and other education stakeholders were concerned that the closures would lead to significant learning loss if children did not receive educational support or engagement at home. To help stem learning loss, the government promoted radio, TV, and internet-based learning content to parents of school-age children. The primary aims of the survey were to understand how children and families responded to the school closures, the education related activities they engaged in, and their strategies to send children back to school. The survey also measures households’ engagement with remote learning content over the period of school closures. We supplement the findings of the parent survey with insights from interviews with Ward Education Officers about their activities during the school closures. The survey sample is comprised of primary care-givers (in most cases, parents) of students enrolled in Grades 3 and 4 during the 2020 school year. The survey builds on an existing panel of students assessed in 2019 and 2020 in a nationally representative sample of schools.4 The parent surveys were conducted using Computer Assisted Telephonic Interviewing (CATI) over a two-week period in early September 2020, roughly two months after the re-opening of primary schools. We report the following key findings from this survey: *Almost all (more than 99 percent) of children in our sample were back in school two months after schools re-opened. The vast majority of parents believed it was either safe or extremely safe for their children to return to school. *Only 6 percent of households reported that their children listened to radio lessons during the school closures; and a similar fraction (5.5 percent) tuned into TV lessons over the same period. Less than 1 percent of those surveyed accessed educational programmes on the internet. Households with access to radio or TV reported higher usage. *Approximately 1 in 3 (36 percent) children worked on the family farm during the closures, with most children working either 2 or 3 days a week. Male children were 6.2 percentage points likelier to work on the family farm than female children. *Households have limited access to education materials for their child. While more than 9 out of 10 households have an exercise book, far fewer had access to textbooks (35 percent) or own reading books (31 percent). *One in four parents (24 percent) read a book to their child in the last week.
