La enseñanza de las ciencias sociales en la formación docente : más allá del texto escrito, el aporte de los lenguajes artísticos

A partir de la Ley Nacional de Educación del año 2006 que extendió la obligatoriedad de la enseñanza al nivel medio, nuevos sectores sociales accedieron a la escuela secundaria. Algunos de los que egresaron, pudieron iniciar carreras de Formación Docente. Lograr el aprendizaje de estos nuevos alumnos planteó un desafío para todos los profesores, entre ellos, los de Ciencias Sociales. Justamente, este trabajo tiene como objetivo compartir algunas reflexiones sobre una experiencia educativa realizada en el marco de una investigación que recibió un subsidio del INFD. El proyecto, “Más allá del texto escrito: la potencialidad de diversos objetos culturales en la formación de docentes", planteaba explorar las potencialidades didácticas de los objetos culturales para la enseñanza de las ciencias sociales, en un contexto de desigualdad y de diversidad cultural. Específicamente, para la investigación se seleccionaron solo los objetos artísticos.Fil: Pipkin, Diana . Universidad de Buenos Aire

Synthesis and transdermal delivery of dual functional phenothiazine ionic liquids

Many pharmaceuticals presently available on the market have disadvantages associated with the solid state (i.e., multiple crystalline states, decreased bioavailability/aqueous solubility, etc.). Prior research has proven that conversion of active pharmaceutical ingredients (APIs) in the solid state to a liquid form (i.e., ionic liquid or IL) is highly advantageous, in that the drug has increased solubility in water or simulated body fluids, improved bioavailability/dissolution, and increased delivery through a skin-mimicking membrane. These liquid state APIs (API-ILs) can also be dual functional, where both drugs forming the IL retain their functionality as well as have synergistic effects. Phenothiazine drugs (PHZ) are good candidates for liquid conversion as they 1.) have disadvantages associated with the solid form, and 2.) have no analgesic effect. Conversion to a liquid form and combination with an NSAID can rectify both of these issues. Here, we synthesized API-ILs of various combinations, with PHZs acting as cations and NSAIDs as anions. Each new API-IL was then purified and analyzed with NMR and IR spectroscopic methods. A select cation and anion were then tested against their respective API-IL combinations via transdermal delivery experiments in order to determine if conversion to a liquid form improved upon the drugs’ delivery through a skin-mimicking membrane

An Analysis of the Tanzanian Public Response to Tanzanian Leadership During the COVID-19 Pandemic

This thesis discusses the similarities and differences in Tanzanian COVID-19 policies implemented by the late President John Pombe Magufuli and his successor, President Samia Suluhu Hassan. It also analyzes the responses of Tanzanian citizens to these different policies as expressed in the media. The conclusions that were made in this thesis are based on qualitative analysis of articles published in Tanzanian-based newspapers during specific time periods surrounding significant policy changes during each presidency. The situation of COVID-19 policies in Tanzania is unique due to the differences in the COVID-19 policies implemented in comparison to those implemented by other countries and also due to the change in leadership in the midst of the pandemic following Magufuli’s tragic death while he was in office. The results of this analysis show that Magufuli and Samia utilized considerably different responses to the pandemic, which Magufuli using a more conservative approach in which citizens choose their individual responses to COVID-19 and Samia using a more involved and scientific approach where citizens are encouraged to follow the recommendations made by the Tanzanian COVID-19 taskforce. Also, this analysis showed that neither president was particularly favored over another in the media, but both presidents received more supportive opinions expressed in the media when they acted in accordance with global health recommendations than when they changed their policies

Essays om det russiske elektrisitets- og kapasitetsmarked

During the past decade the Russian power sector has undergone a dramatic reform. This has created a need for better understanding of the drivers and development of the sector. This dissertation describes the functioning of the Russian power market since 2006 by focusing on price formation, market power and the main regulatory obstacles for competition. Paper I focuses on time regularities in Russian power prices and compares these for the Siberian and the European zones. A set of distinct time regularities is revealed and discussed: “Day-of-the-week pattern”, “Weekend pattern” and “Time-of-the-day pattern”. The magnitudes of the price differences and time lag between the zones raise the question of extending the interconnectors between the zones. The persistence and magnitude of time regularities in power prices in the European zone imply that technologies that allow for flexibility, either on the supply or demand side, can be profitable. Paper II tests for market power in Northwest Russia using the Bresnahan–Lau framework by estimating residual demand and supply curves for thermal producers. I find that price mark-ups are close to 7–8% on average for the hours between 10 am and 9 pm and 2–3% for the remaining hours of the day. The residual demand curve elasticity is relatively high during peak hours. In addition, demand from Finland/Baltic states and Center FFZ24 have different profiles, such that total demand is most elastic during peak hours and least elastic during the periods of rapid change in consumption. The increase in natural gas prices was reflected directly in electricity prices in Northwest Russia in the analysed period. The domestic prices for natural gas are expected to increase to the level of European net-back prices, and given that natural gas will still be the main fuel in electricity production, this price increase will also be reflected in electricity prices. The objective of Paper III is to take into account the mathematical formulation of the Russian power market in the calculation of concentration measures and investigate the role of transmission constraints using the more detailed framework of the transmission constrained residual supply index (TCRSI). The analysis supports the previous findings of high market concentration in the Russian power market, but for different reasons. The adjusted HHI is below 1400 on average for all price zones and UESs and the adjusted RSI shows that there exist pivotal generators for more than 5% of hours in the analysed period only in two of 21 free-flow zones. Nevertheless, the TCRSI reveals that market concentration is critical for most FFZs in Russia in the UC auctions, day-ahead (DAM) and capacity markets. Market concentration decreases the higher is the share of hydro producers and transmission capacity to the neighbouring regions in the Russian power market in general and in addition depends on the share of fixed generation in the DAM. Paper IV investigates the main challenges and obstacles to competition in the Russian power market, especially regarding the role of the SO. The transmission constraints between the European and Siberian zones forced by the SO led to enormous subsidization of the Siberian zone by customers in the European zone in the DAM. In addition, must-run generation forced by the system security constraint and demand for heat affects competition in the capacity market and the UC auctions, which lead to distortions of DAM. The linear demand curve for capacity by price zone provides incentives to exert market power, price cap constraints the potential profits of generators, whereas the lower bound given by the total installed capacity reduces the incentives for competition. On the basis of these findings, I present the following policy recommendations: facilitate consumer response to variation in electricity and capacity prices and invest in flexible technology on supply or demand side; upgrade the existing transmission capacity to discourage the exercise of market power and to deal with the supply security concerns; introduce competitive pricing of heat and fuel (natural gas and coal)

Enhancing the Performance of Anaerobic Bioreactors for the Biological Degradation of Volatiles Organic Compounds in Groundwater Using Alternate Electron Acceptors

Engineered anaerobic bioreactors (ABR) constructed from mixed media and sand can biodegrade high concentrations of volatile organic compounds (VOCs). Sustainable treatment of benzene, toluene, ethylbenzene, and xylenes (BTEX), chlorinated ethenes and ethanes were used to investigate the use of engineered ABRs, while also analyzing the system performance of a full-scale ABR system. Experimentations conducted on environmental and biological factors that affect ABR system performance was conducted through serum bottles, columns, and reactor studies. Column and reactor ABR systems were designed to treat VOCs via biodegradation in groundwater with varying terminal electron acceptors (TEAs). Laboratory-scale column ABRs were constructed to treat BTEX compounds while simultaneously adjusting the TEA processes in the bed between methanogenic and sulfate-reducing conditions. Analysis of the groundwater showed that amending the contaminated water with sulfate lead to higher percentages of degradation of BTEX. Experimentations showed that sizing of a full-scale ABR treatment bed would be controlled by benzene due to the lower removal efficiency and lower required discharge limits. A two-phase pilot-scale ABR system was operated through the use of sequential anaerobic/aerobic ABRs to reductively dechlorinate 1,1,1-trichloroethane (TCA) to chloroethane (CA), followed by aerobic oxidation of CA. Two duplicate reactors operated in parallel in an up-flow mode were prepared for aerobic treatment studies of CA. Pure oxygen was supplied through a porous silastic tube under pressure with a pure oxygen gas cylinder. Investigations concluded that complete mineralization of chloroethane was observed in the effluents from the aerobic zone of the ABR system. During both studies, TEA changes were confirmed by using a 16S rRNA assessment of microbial populations within the ABR beds, which indicated a shift in bacteria and/or archaea to a more effectual degrading community structure. Two full-scale ABR beds were analyzed for system performance through two sampling trips to the ReSolve, Inc. Superfund Site. Groundwater samples were collected along the length of both ABRs for analysis of chlorinated ethenes and ethanes, while suspended and attached bacteria samples were collected via groundwater and core sampling. Data collected from the Site determined that the ABRs displayed consistent losses of chlorinated ethenes and ethanes, with the exception of minor CA accumulation in the ABRs in 2014, with CA degradation occurring in 2015, showing that the system performance improved over the course of the year

Identifying Team Dysfunctions within Two Natural Resources Conservation Service Offices

Many teams fail to recognize what causes dysfunction within their team. The purpose of this study is to examine team dynamics and produce an example of applied leadership research for leadership educators. By identifying the causes of dysfunction, teams will be able to advance the functionality and success of their team by achieving a higher level of cohesiveness and production for the customers and communities in which they serve. Leadership educators will be able to use this study in discussing how team functionality can be studied and improved. NRCS offices in two counties were given the opportunity to participate in this study to evaluate dysfunction within their team. One instrument was used during this study for data collection, a Team Dysfunction Assessment Questionnaire (Lencioni, 2002). The Team Dysfunction Assessment Questionnaire was developed as a diagnostic tool for evaluating team susceptibility to five dysfunctions (Lencioni, 2002). The mean scores for NRCS Office One indicated all five dysfunctions could be a problem. The mean scores for NRCS Office Two indicated the dysfunctions were not a problem except for avoidance of accountability. The mean score for avoidance of accountability indicated the dysfunction could be a problem. Based upon the findings of this study, recommendations for future research were made. After results are shared with each office, a follow-up study should be conducted to determine if the dysfunctions are continuing to persist, and what techniques and team exercises were effective or not effective when seeking to correct the dysfunction. Future research should determine if the case study is an effective exercise in helping undergraduate students acquire the skills and dispositions needed to be better team members and leaders
