In the middle of 2019, Thailand introduced an urgent measure to solve the haze and fine particles problem caused by preharvest sugarcane. The measure is to eradicate the burning of sugarcane before harvesting within the next four years. This study focuses on estimation of future reduced air emissions from the implementation of this measure. The study results showed that without the implementation of the measure in the production season 2022/23, the amount of burned sugarcane will be as high as 102.4 ± 1.0 Mt/yr, resulting in the release of small particulate matter of 2.5 microns or less in diameter (PM2.5) emissions into the atmosphere at 30.6 ± 8.6 kt/yr, which is about a 21% increase in emissions from the 2018/19 season. However, with the government’s enforcement of the measure to reduce burned sugarcane, the amount of air emissions will immediately be reduced in the first year. In order to effectively implement the sugarcane burning reduction measure, in which the harvesting methods will change from cutting burned sugarcane to cutting fresh sugarcane with human labor and with machinery, the government must provide financial support, to farmers, of approximately 3.3 USD per ton of fresh sugarcane for the use of human labor and 2.9 USD per ton of fresh sugarcane for the use of machinery. The costs of investment to reduce PM2.5 emissions can be calculated in the range of 9.7−11.0 million USD per kiloton of PM2.5.

The Government of Indonesia plans to build 9 gas power plants in South Kalimantan, South Sulawesi and Southeast Nusa Tenggara with a total power capacity of 780 MW with an estimated actual gas demand of 46.56 MMSCFD which are planned to be supplied by the Bontang terminal, DS-LNG, Masela LNG, and Tangguh LNG. LNG-C logistics optimization is needed to get the best transportation scenario regarding the eastern region which consists of scattered islands and inadequate infrastructure. This study analyzes and evaluates the best-case scenarios by comparing the time and cost variables. The process of planning the supply chain starts from determining the upstream-downstream distribution scheme and then calculates the shipping distance which results in the determination of the quantity, capacity and shipping of the LNG-C. Based on the analysis and calculation of the logistics, it is concluded that there are 3 divisions of clusters of Kalimantan-Sulawesi, NTT and NTB having estimated needs in a row of 18.06, 18.8, and 9.7 MMSCFD with the Milk-Run transportation method. Logistics optimization results show that scenario 1 has an efficiency value of 87% with an LNG-C transport capacity of 0.35 MMSCF, a roundtrip cruise time of 8.6 days and the number of shipments is 36 / year. The detailed analysis of costs in scenario A is 1-2 USD / MMBTU for the milk and run transportation method, 1.49-1.73 USD / MBTU for LNG-C transport costs, and regasification costs which are 1.0-3.7 USD / MMBTU. Based on the above results it can be calculated that the price of gas in the first year of implementation was 13.4 USD / MMBTU, so the total value below this supply chain was Rp.8,812,876,800.00. Therefore, this idea was created as a solution for the initial steps for the utilization of the domestic natural gas distribution

The ideological struggle deployed between the Syrian opposition groups and the government during the first year of the Syrian popular uprising is examined in this paper. Force alone was not enough for the regime to crush the revolt, at least during its first twelve months, while protesters were unable to bring down the government. The battle for cultural hegemony had to be won by one of the two sides. Protesters and the regime alike had to deploy their discourses along frames that resonated with the values, hopes and fears of Syrians. The effectiveness of the regime in securing the support of large sections of urban dwellers and its systematic violent repression led to frustration on the part of demonstrators, who ended up supporting at least morally the armed struggle. A stalemate was reached. This led to divergent framing activity within the opposition, which in turn led to its division.Spanish El artículo examina la lucha ideológica que se dio entre los grupos sirios de oposición y el gobierno durante el primer año del levantamiento popular en Siria. Durante los primeros 12 meses a partir de marzo de 2011, al régimen no le bastó con la fuerza bruta para aplastar la revuelta, aunque los manifestantes tampoco lograron tumbar al gobierno. Se dio un combate por la hegemonía cultural y uno de los bandos necesitaba ganarla. Tanto los opositores como el régimen frasearon sus discursos alrededor de aristas conceptuales (frames) en armonía con los valores, esperanzas y temores de la población siria. La e ficacia del régimen en obtener el apoyo de amplios sectores de los habitantes de las principales ciudades y la represión violenta sistemática condujeron a un sentimiento de frustración entre los manifestantes, que terminaron ofreciendo un apoyo al menos moral a la lucha armada. Se llegó a un impasse. Esto a su vez llevó a que diferentes grupos de oposición reconstruyeran su discurso en torno de aristas distintas, lo que generó división.French L'article étudie la lu e idéologique menée entre les groupes d'opposition et le gouvernement pendant la première année du soulèvement populaire en Syrie. Pendant les douze premiers mois, à dater du mois de mars de 2011, la force brute n'a pas suffiau régime pour écraser le mouvement, bien que les manifestants à leur tour n'aient pas réussi à faire tomber le gouvernement. Une lu e pour l'hégémonie culturelle s'est développée et un des deux côtés devait la gagner. L'opposition ainsi que le régime ont encadré (frame) leurs discours de sorte à qu'ils parlent aux valeurs, espoirs et peurs des syriens. Le succès du régime à gagner l'appui (ou le recul) de grands secteurs de la population des villes principales et la répression violente systématique ont produit un sentiment de frustration parmi les manifestants, qui ont fini par soutenir la lu e armée au moins moralement. La situation est arrivée à une impasse. Dans cet état, différents groupes d'opposition ont reformulé leurs discours au tour d'encadrements divergents, ce qui a mené à leur division.

Abstract The paper analyzes the relations between the government and Civil Society Organizations (CSOs) during the COVID-19 pandemic in Israel. The paper presents the inconsistent policy of the government, which has been influenced by various interest groups and the very limited financial support allocated to CSOs during the health, economic and social crisis. The paper describes the government’s alienated attitude toward the CSOs as well as the reasons for that behavior. Special attention is devoted to the government’s misunderstanding of the mission and roles of CSOs in modern society, especially at times of crisis and national disasters. The paper also analyzes the organizational and strategic behavior of CSOs toward the government, which has also contributed to the alienated attitude of the government toward them. I argue that relations between CSOs and the government should be based on more trust, mutuality, and understanding on the part of both actors in order to change power-dependence relations, and that there is a need to establish more cross-sectoral partnerships for the benefit of citizens.

Objective. To investigate the role of CD4+CD25+T cells (Tregs) in protecting fine particulate matter (PM-) induced inflammatory responses, and its potential mechanisms.Methods. Human umbilical vein endothelial cells (HUVECs) were treated with graded concentrations (2, 5, 10, 20, and 40 µg/cm2) of suspension of fine particles for 24h. For coculture experiment, HUVECs were incubated alone, with CD4+CD25−T cells (Teff), or with Tregs in the presence of anti-CD3 monoclonal antibodies for 48 hours, and then were stimulated with or without suspension of fine particles for 24 hours. The expression of adhesion molecules and inflammatory cytokines was examined.Results. Adhesion molecules, including vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1), and inflammatory cytokines, such as interleukin (IL-) 6 and IL-8, were increased in a concentration-dependent manner. Moreover, the adhesion of human acute monocytic leukemia cells (THP-1) to endothelial cells was increased and NF-κB activity was upregulated in HUVECs after treatment with fine particles. However, after Tregs treatment, fine particles-induced inflammatory responses and NF-κB activation were significantly alleviated. Transwell experiments showed that Treg-mediated suppression of HUVECs inflammatory responses impaired by fine particles required cell contact and soluble factors.Conclusions. Tregs could attenuate fine particles-induced inflammatory responses and NF-κB activation in HUVECs.

Tax compliance is the willingness of taxpayers to obey tax rules of a nation, whilst tax noncompliance is the unwilling behaviour of citizens to act under tax regulations. Taxpayer compliance enables the government to collect tax revenues, which is one of the most important sources of government income. Altering the non-compliant behaviour of citizens is an important barometer for increasing tax revenues that contribute to the socio-economic development of a nation. Numerous quondam studies have been conducted strikingly in the past few decades on taxpayer compliance. However, there is a dearth of sufficient research currently on tax noncompliance behaviour. Moreover, the phenomenon of tax noncompliance has limited exploration from the vantage point of meta-analysis of primary research studies conducted, focussing on interrogating, and systematically categorising their results. Resultantly, the purpose of this study was to examine the previously related primary studies to determine those factors that have been judged to have influenced the tax compliance behaviour of citizens. This study has adopted the quantitative research approach and followed the preferred reporting items for systematic review (PRISMA) method and meta-analysis to provide an accurate estimate of the relationship that exists in a population of relevant tax noncompliance behavioural studies. The population comprised of 45 international studies conducted between the period 2015 to 2020 is selected for analysis. The study results indicate that the quality of tax administration systems and public trust in institutional governance are factors that have influenced taxpayer compliance positively. Poor government accountability mechanisms entrenched tax gaps, and developing public trust in government institutions were found to be universal to promote voluntary taxpayer compliance. This study has contributed significantly to the open discussion on tax compliance among researchers, governments, and businesses.

Purpose Retention is one of the key performance indicators in university quality assurance processes. The purpose of this paper is to identify the causes leading to low retention rates for first-year undergraduate computing students in a UK higher education institution (HEI). Design/methodology/approach The study applies Tinto’s student integration theory, and connects it with the behavioural patterns of students. Data were collected from 901 students using Pascarella and Terenzini’s questionnaire (integration scales). This data were combined with student enrolment information and analysed using the structural equation modelling technique. Findings The study results indicate that Tinto’s student integration theory is useful in analysing student retention, but this accounts for only a modest amount of variance in retention. Nevertheless, important relationships amongst student’s initial and later academic goals and commitments have been identified through this new approach to analysing retention. The largest direct effect on retention was accounted for by initial goals and institutional commitments, followed by later goals and institutional commitments. In addition, the results show that academic and social integration constructs can have an influence on the student retention processes. When all, or some, of these relationships are operating towards students’ benefits, appropriate services or programmes, such as student support systems, can have their maximum benefits. Originality/value The authors mapped behavioural-related retention factors using a learning community lens. The study explored students’ social and learning experiences within the context of a UK HEI by employing Tinto’s model. This is the first time the model has been tested in this context.

This study explores electronic portfolios and their potential to assess student literacy and self-regulated learning in elementary-aged children. Assessment tools were developed and include a holistic rubric that assigns a mark from 1 to 5 to self-regulated learning (SRL) and a mark to literacy, and an analytical rubric measuring multiple sub-scales of SRL and literacy. Participants in grades 4, 5 and 6 across two years created electronic portfolios, with n=369 volunteers. Some classes were excluded from statistical analyses in the first year due to low implementation and some individuals were excluded in both years, leaving n=251 included in analyses. All portfolios were coded by two coders, and the inter-rater reliability explored. During the first year Cohen’s kappa ranged from 0.70 to 0.79 for literacy and SRL overall, but some sub-scales were unacceptably weak. The second year showed improvement in Cohen’s kappa overall and especially for the sub-scales, reflecting improved implementation of the portfolios and use of the assessment tools. Validity was explored by comparing the relationship of portfolio scores to other measures, including the government scores on the open-response literacy questions for the Canadian Achievement Tests (version 4), the scores we assigned to the CAT-4s using our assessment tools, and scores on the Student Learning Strategies Questionnaire (SLSQ) measuring SRL. The portfolio literacy scores correlated (p

Air quality in Kampala, the capital of Uganda, has deteriorated significantly in the past two decades. We made spot measurements in Mpererwe district for airborne particulate matter PM2.5(fine particles) and coarse particles. PM was collected on Teflon-membrane filters and analyzed for mass, 51 elements, 3 anions, and 5 cations. Both fine and coarse particle concentrations were above 100 µg/m3in all the samples collected. Markers for crustal/soil (e.g., Si and Al) were the most abundant in the PM2.5fraction, followed by primary combustion products from biomass burning and incinerator emissions (e.g., K and Cl). Over 90% of the measured PM2.5mass can be explained by crustal species (41% and 59%) and carbonaceous aerosol (33%–55%). Crustal elements dominated the coarse particles collected from Kampala. The results of this pilot study are indicative of unhealthy air and suggest that exposure to ambient air in Kampala may increase the burden of environmentally induced cardiovascular, metabolic, and respiratory diseases including infections. Greater awareness and more extensive research are required to confirm our findings, to identify personal exposure and pollution sources, and to develop air quality management plans and policies to protect public health.
