Increasing Access to Clean Cooking: The Practicality of Pay-Go in Promoting Adoption of Bottled Gas in Kinondoni, Dar Es Salaam, Tanzania

The majority of the population in developing countries have limited access to clean energy. To increase access to clean energy, the governments and other stakeholders have been working hard to create enabling environments for their adoption and utilization. For the household cooking sector, technological innovations such as improved biomass fuels, improved biomass cookstove, solar cooking, biogas and recently bottled gas service have been or are being deployed to scale up clean cooking. Nevertheless, a good number of the innovations intended for upscaling clean cooking in developing countries have failed to meet the desired goals due to limited support from the national governments or the international community. Pay-Go is among the recent innovations in the East African region intended for promoting the use of bottled gas (liquefied petroleum gas-LPG). This study evaluates the practicality of Pay-Go innovation on bottled gas, popularly known as Pay-as-you-Cook. Specifically, the article examines the evolution of Pay-as-you-Cook, its execution, usefulness and challenges;and its implications on household energy sector development. The study was conducted in Kinondoni Municipality, Dar es Salaam, Tanzania between 2018 and 2020. The study used both qualitative and quantitative approaches. Purposive and non-random sampling techniques were used in selecting respondents. Purposive sampling was used to identify key informants while snowball sampling was used to find household respondents. Information was gathered from KopaGas (Pay-as-you-Cook innovator) headquarter-Kinondoni Morocco;and from Pay-as-you-Cook clients in Kinondoni Moscow, Mkwajuni and Hananasif. Methods of data collection involved semi-structured interviews and observation. Instruments of data collection included interview guides and observation checklists. Data analysis was accomplished with Nvivo 12. Findings show that Pay-as-you-Cook innovation was intended for promoting bottled gas adoption mainly to low-income households. The innovation was discovered to be convenient to many low- income households as it enabled them to use bottled gas for cooking without necessarily climbing the economic ladder. Yet, the innovation presents several challenges which are doubtful to its practicality.

Understanding the Human Rights of Modern Individuals—Revisiting Habermas’s Dual Critique and the Reconstruction of Intersubjectivity

Human rights are not only pivotal in depicting the relationship between individuals and communities but also a focal point of political philosophical concerns oriented towards reality. The inseparability of human rights from individual self-identity reveals a contradiction between practicality and historicity in understanding individuals, as highlighted in the debate between liberalism and communitarianism. In order to reconcile this contradiction, Habermas,drawing from German classical philosophy, examines practicality and historicity separately: while Fichte intertwines objectivity in self-identity, revealing the practicality of individuals but neglecting their real elements, Hegel interprets self-identity under the concept of unity,examining individuals from a historical dimension but letting rational rules dominate reality. Ultimately, Habermas reconstructs the process of modern individual self-identity from the theory of communicative action by critiquing the shackles of subjective philosophy. He not only reconciles the divergence between practicality and historicity in self-identity, but also elucidates the intersubjective core inherent in human rights.

Shock index and its variants as predictors of mortality in severe traumatic brain injury

BACKGROUND The increase in severe traumatic brain injury(sTBI)incidence is a worldwide phenomenon,resulting in a heavy disease burden in the public health systems,specifically in emerging countries.The shock index(SI)is a physiological parameter that indicates cardiovascular status and has been used as a tool to assess the presence and severity of shock,which is increased in sTBI.Considering the high mortality of sTBI,scrutinizing the predictive potential of SI and its variants is vital.AIM To describe the predictive potential of SI and its variants in sTBI.METHODS This study included 71 patients(61 men and 10 women)divided into two groups:Survival(S;n=49)and Non-survival(NS;n=22).The responses of blood pressure and heart rate(HR)were collected at admission and 48 h after admission.The SI,reverse SI(rSI),rSI multiplied by the Glasgow Coma Score(rSIG),and Age multiplied SI(AgeSI)were calculated.Group comparisons included Shapiro-Wilk tests,and independent samples t-tests.For predictive analysis,logistic regression,receiver operator curves(ROC)curves,and area under the curve(AUC)measurements were performed.RESULTS No significant differences between groups were identified for SI,rSI,or rSIG.The AgeSI was significantly higher in NS patients at 48 h following admission(S:26.32±14.2,and NS:37.27±17.8;P=0.016).Both the logistic regression and the AUC following ROC curve analysis showed that only AgeSI at 48 h was capable of predicting sTBI outcomes.CONCLUSION Although an altered balance between HR and blood pressure can provide insights into the adequacy of oxygen delivery to tissues and the overall cardiac function,only the AgeSI was a viable outcome-predictive tool in sTBI,warranting future research in different cohorts.

Assessment of soil erosion in the Irga watershed on the eastern edge of the Chota Nagpur Plateau,India

Human activities to improve the quality of life have accelerated the natural rate of soil erosion.In turn,these natural disasters have taken a great impact on humans.Human activities,particularly the conversion of vegetated land into agricultural land and built-up area,stand out as primary contributors to soil erosion.The present study investigated the risk of soil erosion in the Irga watershed located on the eastern fringe of the Chota Nagpur Plateau in Jharkhand,India,which is dominated by sandy loam and sandy clay loam soil with low soil organic carbon(SOC)content.The study used the Revised Universal Soil Loss Equation(RUSLE)and Geographical Information System(GIS)technique to determine the rate of soil erosion.The five parameters(rainfall-runoff erosivity(R)factor,soil erodibility(K)factor,slope length and steepness(LS)factor,cover-management(C)factor,and support practice(P)factor)of the RUSLE were applied to present a more accurate distribution characteristic of soil erosion in the Irga watershed.The result shows that the R factor is positively correlated with rainfall and follows the same distribution pattern as the rainfall.The K factor values in the northern part of the study area are relatively low,while they are relatively high in the southern part.The mean value of the LS factor is 2.74,which is low due to the flat terrain of the Irga watershed.There is a negative linear correlation between Normalized Difference Vegetation Index(NDVI)and the C factor,and the high values of the C factor are observed in places with low NDVI.The mean value of the P factor is 0.210,with a range from 0.000 to 1.000.After calculating all parameters,we obtained the average soil erosion rate of 1.43 t/(hm^(2)•a),with the highest rate reaching as high as 32.71 t/(hm^(2)•a).Therefore,the study area faces a low risk of soil erosion.However,preventative measures are essential to avoid future damage to productive and constructive activities caused by soil erosion.This study also identifies the spatial distribution of soil erosion rate,which will help policy-makers to implement targeted soil erosion control measures.

An optimized strategy of nitrogen-split application based on the leaf positional differences in chlorophyll meter readings

Modern rice production faces the dual challenges of increasing grain yields while reducing inputs of chemical fertilizer.However,the disequilibrium between the nitrogen(N)supplement from the soil and the demand for N of plants is a serious obstacle to achieving these goals.Plant-based diagnosis can help farmers make better choices regarding the timing and amount of topdressing N fertilizer.Our objective was to evaluate a non-destructive assessment of rice N demands based on the relative SPAD value(RSPAD)due to leaf positional differences.In this study,two field experiments were conducted,including a field experiment of different N rates(Exp.I)and an experiment to evaluate the new strategy of nitrogen-split application based on RSPAD(Exp.II).The results showed that higher N inputs significantly increased grain yield in modern high yielding super rice,but at the expense of lower nitrogen use efficiency(NUE).The N nutrition index(NNI)can adequately differentiate situations of excessive,optimal,and insufficient N nutrition in rice,and the optimal N rate for modern high yielding rice is higher than conventional cultivars.The RSPAD is calculated as the SPAD value of the top fully expanded leaf vs.the value of the third leaf,which takes into account the non-uniform N distribution within a canopy.The RSPAD can be used as an indicator for higher yield and NUE,and guide better management of N fertilizer application.Furthermore,we developed a new strategy of nitrogen-split application based on RSPAD,in which the N rate was reduced by 18.7%,yield was increased by 1.7%,and the agronomic N use efficiency was increased by 27.8%,when compared with standard farmers'practices.This strategy of N fertilization shows great potential for ensuring high yielding and improving NUE at lower N inputs.

Research on the development methodology for clinical practice guidelines for organic integration of traditional Chinese medicine and Western medicine

Integrated traditional Chinese medicine(TCM)and Western medicine(WM)is a new medical science grounded in the knowledge bases of both TCM and WM,which then forms a unique modern medical system in China.Integrated TCM and WM has a long history in China,and has made important achievements in the process of clinical diagnosis and treatment.However,the methodological defects in currently published clinical practice guidelines(CPGs)limit its development.The organic integration of TCM and WM is a deeper integration of TCM and WM.To realize the progression of"integration"to"organic integration",a targeted and standardized guideline development methodology is needed.Therefore,the purpose of this study is to establish a standardized development procedure for clinical practice guidelines for the organic integration of TCM and WM to promote the systematic integration of TCM and WM research results into clinical practice guidelines in order to achieve optimal results as the whole is greater than the sum of the parts.

Contraceptive behaviors and awareness in an urban slum community of south India

Objective:To assess the factors associated with knowledge,attitude and behavior of contraception use among urban slum population in Chennai.Methods:A cross-sectional study was conducted in the urban slum of Anakaputhur,Chennai.Married couples between ages of 19-49 years and living in slum areas were taken up for the study by simple random sampling.Pregnant women,postnatal and postmenopausal women were excluded from the study.Data collection was done using a pretested structured questionnaire focusing on details regarding contraception knowledge,attitude,and practices.Data analysis was done using IBM SPSS version 22.Analytical test like Chi square and odds ratio(OR)were used to identify association between knowledge,attitude,and behavior of contraception with the associated variables and enter method of logistic regression analysis was done.Results:Out of the 360 respondents,228 were females,with a mean age of(34±5)years.Approximately 43%demonstrated adequate knowledge of contraception use,and 91%were aware of at least one contraceptive method.Notably,72%exhibited a positive attitude towards contraceptive use.Nevertheless,43%(155 individuals)did not utilize any contraceptive method.Among contraceptive users,intrauterine devices were the most commonly adopted,followed by barrier methods and female sterilization.There was significant association between knowledge of contraception and education(aOR 7.29,95%CI 2.93-18.10,P<0.05),age(aOR 2.04,95%CI 1.19-3.50,P<0.05)and socioeconomic class(aOR 3.66,95%CI 1.71-7.85,P<0.05;aOR 3.97,95%CI 2.12-7.49,P<0.05).Regarding attitude towards contraception use,education(aOR 8.54,95%CI 2.35-31.03,P<0.05),sex(aOR 0.15,95%CI 0.06-0.37,P<0.05),age(aOR 0.53,95%CI 0.28-0.99,P<0.05),socio-economic class(aOR 4.42,95%CI 1.97-9.92,P<0.05;aOR 9.83,95%CI 3.63-26.58,P<0.05)and number of children(aOR 10.04,95%CI 4.26-23.66,P<0.05)were the variables that had a significant association.Conclusions:These findings underscore the imperative for enhanced dissemination of health education pertaining to contraception use within the slum population.The health sectors of the area and other stakeholders need to make sure to extend penetration of family planning related services to the urban slum population.

Water and nitrogen footprint assessment of integrated agronomic practice management in a summer maize cropping system

The footprints of water and nitrogen(WF and NF)provide a comprehensive overview of the type and quantity of water consumption and reactive nitrogen(Nr)loss in crop production.In this study,a field experiment over two years(2019 and 2020)compared three integrated agronomic practice management(IAPM)systems:An improved management system(T2),a high-yield production system(T3),and an integrated soil-crop management system(ISCM)using a local smallholder farmer’s practice system(T1)as control,to investigate the responses of WF,Nr losses,water use efficiency(WUE),and nitrogen use efficiency(NUE)to IAPM.The results showed that IAPM optimized water distribution and promoted water use by summer maize.The evapotranspiration over the whole maize growth period of IAPM increased,but yield increased more,leading to a significant increase in WUE.The WUE of the T2,T3,and ISCM treatments was significantly greater than in the T1 treatment,in 2019 and 2020respectively,by 19.8-21.5,31.8-40.6,and 34.4-44.6%.The lowest WF was found in the ISCM treatment,which was 31.0%lower than that of the T1 treatment.In addition,the ISCM treatment optimized soil total nitrogen(TN)distribution and significantly increased TN in the cultivated layer.Excessive nitrogen fertilizer was applied in treatment T3,producing the highest maize yield,and resulting in the highest Nr losses.In contrast,the ISCM treatment used a reduced nitrogen fertilizer rate,sacrificing grain yield partly,which reduced Nr losses and eventually led to a significant increase in nitrogen use efficiency and nitrogen recovery.The Nr level in the ISCM treatment was34.8%lower than in the T1 treatment while NUE was significantly higher than in the T1 treatment by 56.8-63.1%in2019 and 2020,respectively.Considering yield,WUE,NUE,WF,and NF together,ISCM should be used as a more sustainable and clean system for sustainable production of summer maize.

Knowledge, attitudes, and practices regarding Covid-19 and their relationship with Covid-19 booster vaccination status among women with infertility

Objective:To elucidate the relationship among knowledge,attitudes,and practices regarding Covid-19 and their relationship with booster vaccination status among women with infertility.Methods:This questionnaire-based cross-sectional study was performed online and offline among women with infertility who visited an infertility clinic in Jakarta,Indonesia.We assessed the patient’s knowledge,attitudes,and practices regarding Covid-19 and their relationship with booster vaccination status and sociodemographic profile.Results:A total of 178 subjects participated in this study,and most participants(92.6%)had received booster Covid-19 vaccines.From the questionnaire,74.2%had good knowledge,and 99.4%had good attitudes regarding Covid-19;however,only 57.9%of patients had good practices.A weak positive correlation existed between knowledge and attitudes(r=0.11,P=0.13)and a moderate negative correlation between attitudes and practices(r=-0.44,P=0.56).Participants’knowledge about vaccines and infertility was correlated with booster vaccination status(P=0.04).Academic background(P=0.01)and attitudes(P=0.01)were also correlated with booster vaccination status.The significant determinants of hesitance of receiving Covid-19 booster vaccines were high school education or below(OR=0.08,95%CI 0.02-0.36)and poor practices(OR=0.21,95%CI 0.05-0.95).Conclusions:The majority of the participants had received the Covid-19 booster vaccine and had good knowledge and attitudes but poor practices regarding Covid-19.Most participants had poor knowledge about the relationship between infertility and the Covid-19 vaccine.The general population should be more informed and reminded about practices to prevent Covid-19 and the relationship between vaccination and fertility to increase the number of people who receive Covid-19 booster vaccines.

The response of roots and the rhizosphere environment to integrative cultivation practices in paddy rice

Integrative cultivation practices(ICPs)are essential for enhancing cereal yield and resource use efficiency.However,the effects of ICP on the rhizosphere environment and roots of paddy rice are still poorly understood.In this study,four rice varieties were produced in the field.Each variety was treated with six different cultivation techniques,including zero nitrogen application(0 N),local farmers’practice(LFP),nitrogen reduction(NR),and three progressive ICP techniques comprised of enhanced fertilizer N practice and increased plant density(ICP1),a treatment similar to ICP1 but with alternate wetting and moderate drying instead of continuous flooding(ICP2),and the same practices as ICP2 with the application of organic fertilizer(ICP3).The ICPs had greater grain production and nitrogen use efficiency than the other three methods.Root length,dry weight,root diameter,activity of root oxidation,root bleeding rate,zeatin and zeatin riboside compositions,and total organic acids in root exudates were elevated with the introduction of the successive cultivation practices.ICPs enhanced nitrate nitrogen,the activities of urease and invertase,and the diversity of microbes(bacteria)in rhizosphere and non-rhizosphere soil,while reducing the ammonium nitrogen content.The nutrient contents(ammonium nitrogen,total nitrogen,total potassium,total phosphorus,nitrate,and available phosphorus)and urease activity in rhizosphere soil were reduced in all treatments in comparison with the non-rhizosphere soil,but the invertase activity and bacterial diversity were greater.The main root morphology and physiology,and the ammonium nitrogen contents in rhizosphere soil at the primary stages were closely correlated with grain yield and internal nitrogen use efficiency.These findings suggest that the coordinated enhancement of the root system and the environment of the rhizosphere under integrative cultivation approaches may lead to higher rice production.
