Trends and Economic Dynamics of Guar in India
Authors: Sindhuja Sambu
Published: January 2023

Guar was once a low-value crop, but recent changes in global markets have made guar crops that fetch large profits. The value of exports of Indian guar products increased at a galloping  pace from 602.95 to 21287.01 crores during 2000–2013, making guar products the largest agricultural export in those years. However, the value of exports later declined to 1949.07 crores in 2020–21. The proportion of guar gum powder in total guar products exported from India has remained high, ranging between 61-66 % (in terms of quantity) and 75 % (in terms of value) for the last five years. The study focused on the global production and trade of guar products, the composition of guar products exported from India, trends and variations in guar production, trends in prices, major aspects of demand and supply, uses of guar products, and their derivatives. The guar area, production, and productivity in India showed a positive trend in the last 20 years (2000-2020). Monthly and seasonal fluctuations in guar prices have been observed over time. As for the long-term trend, guar prices in Rajasthan, Gujarat, and Haryana increased gradually from January 2003 to June 2010 and, after that, continued to drop sharply. The supply of guar is greatly dependent on the amount and pattern of precipitation as its cultivation is restricted to dry regions of the country. Globally, oil drilling and mining is the primary consumer industry of guar gum. Farmers and industrialists confront significant obstacles, i.e., price instability, low productivity, unpredictable guar output, low investment in R&D, etc.
Households’ Willingness to Pay for Improved Water Supply System in the Dryland areas of West Bengal – an estimation using Double-Bounded Dichotomous-Choice Model
Authors: Chatterjee Nilendu
Published: January 2023

This study used double-bounded dichotomous-choice to estimate and analyze the factors affecting households’ willingness to pay (WTP) for water supply in the dryland areas of West Bengal as well as improvement in the existing water bodies. This study notes that although the households living in the four districts of drylands of West Bengal are very poor financially, majority of them have willingness to accept the higher bid in the double-bounded bidding process. It shows the importance as well as necessity of good water system, as a whole, to them, which could solve manifold problems. Pilot survey as well as final survey were conducted in the three districts of dryland area of West Bengal on 450 households and bids were set in such a manner which could be bearable for the people of these areas. Over 65% were willing to participate in the improvement of the water supply system in the area. Those who were “protest bidders”, showed socio-economic reasons for their decisions. We have followed the procedure suggested by NOAA (1993) panel for applying the CVM with full randomness being taken care of in the different stages of survey. What we have found is that apart from the amount of bid, several socio-economic variables play a part in people’s decision on selection of a bid.

Authors: Thakur Pankaj
Published: January 2023

The market channel choice are the contributing issues which has impact on production and sales of cauliflower crop. Despite their importance, yet adequate research has not been carried out on it, particularly in hill regions of India. Considering this, the present study focuses on the factors affecting cauliflower farmers’ choice of output marketing channels and what level their market choice influences the market participation in Himachal Pradesh. The field survey was employed on a sample of 200 farmers through field interviews based on a structured questionnaire. The multinomial logistic regression model was employed to determine the factors influencing farmers’ choice for output marketing channels. The finding of this paper reveals that there are five output marketing channels used by cauliflower growers in the study area, producer-retailer-consumer (1%) followed by producer-retailer-consumer (2.50%) producer-commission agent-retailer-consumer (39%), local trader-wholesaler-retailer-consumer (24%) and producer-wholesaler-retailer-consumer (33.50%) respectively. Further, the empirical results shows that education, farm income, experience, market distance market information found to be significant at 1%, 5% and 10% significant level which affects farmers choice to choose marketing channel. However, slows sale slow sales of cauliflower crop in marketing Channel-A affects farmers choice to participate in other marketing channels such as Channel-B, D and E. Moreover, the study concluded with the suggestion for development of suitable institutional support programmes, such as public–private partnerships, to better connect farmers to markets.

PT Jahermosa is an international freight forwarding company established in 2012. This company has experience handling several types of goods with various services and modes of transportation. The services provided include export-import goods delivery using sea, air, and land modes. Due to COVID-19, the company’s sales performance has decreased from 2019 to 2021. However, according to data from the Central Bureau of Statistics, Indonesia’s total exports and imports from 2020 to 2021 have experienced a drastic increase. This gap indicates an increase in the market for goods delivery services to and from Indonesia but did not accompany PT Jahermosa’s ability to absorb the market. Therefore, this study aims to provide strategic business proposals for PT Jahermosa in the freight forwarding industry to improve the company’s sales performance. This research is qualitative research using primary data and secondary data. Primary data was obtained through interviews with several customers and management participants. While secondary data is obtained through company financial reports, websites, journals, and articles. First, an analysis was carried out on the external and internal conditions of PT Jahermosa’s freight forwarding business. External analysis was conducted using the PESTEL Framework, Porter’s Five Forces Model, Customer Analysis, and Competitor Analysis. Meanwhile, internal analysis was carried out using the Resource Based View Model, VRIO Analysis, Porter Value Chain Analysis. After that, the internal and external analysis will be put into the Business Model Canvas. Then, SWOT analysis is used to evaluate the strengths, weaknesses, opportunities, and threats to assess the condition of PT Jahermosa using the data from external and internal analysis. Evaluation of these four factors forms the basis for formulating strategic alternatives using the TOWS Matrix. Finally, root cause analysis is carried out to find the real cause of the problems encountered using Problem Tree Analysis. Based on the results of this research, the strategy is formulated using the Diamond Strategy Model by considering four factors: vehicles, arenas, differentiators, speed, and economic logic. Value proposition canvas is used to support the proposed strategy. The limitation of this research is that financial reports need to be explained in detail to keep company documents secret. In addition, this research only covers PT Jahermosa as a freight forwarding and logistics service company. Further investigation can be made based on this research in the supply chain management, human resource management, and marketing strategy.

Published: January 2023

High turnover is one of the problems faced by companies, especially small and medium enterprises. PT Fakta Asia Jaya, or Fakta Retail or Fakta Group, is one of the oldest semi-modern paint chain retailers and experiences a high turnover rate, more than the average industry. The company services depended on employee knowledge and support. The higher turnover rate becomes the real problem with the cost of hiring, training, sales, and services, which might affect profitability in the long run. Many factors, such as age (generational differences), gender, length of work, marital status, job satisfaction, compensation satisfaction, and organizational culture, influence employees’ decision to leave the company. This research uses qualitative methodology through an in-depth interview approach with questions about job satisfaction, compensation satisfaction, and organizational culture conducts information collected. This approach was chosen to understand whether those factors significantly influence their decision. This study proposes a recommendation for the business situation and to retain the current employee, especially the millennial generation. Based on the result of the study, it was suggested that the factors related to the employee leaving are mainly personal reasons and related to job satisfaction and compensation benefit. The other aspect emphasized by millennials is looking for career advancement and work-life balance between the family. Also, it is found that the higher risk of the job tends to look at a higher salary or to be financially incentivized; the importance of being valued and communicating in every variable makes all generations feel satisfied and fulfilled.

Global business conditions and rupiah exchange rate fluctuations have also contributed to the oil and gas market decline since the outbreak of the novel coronavirus (Covid-19) pandemic in Indonesia in the first quarter of 2020. In addition, the existing state of oil and gas, which generally experiences periodic declines, is a challenge for the company to maintain the company’s business. Oil and gas companies, like other businesses, need people to carry out their activities and meet their production targets. The oil and gas business, by its very nature, requires sufficient human resources in terms of numbers and skills. If this is not regulated, it can lead to understaffing affecting goal achievement or over-employment, which can reduce company productivity. This study therefore aims to ensure adequate worker availability through workforce planning. Based on current personnel analysis and personnel planning strategy, PT. X has many flaws in its workforce planning/strategy, including its productivity, unstable headcount, lack of talent development and leadership skills The strategic manpower framework for the internal labor market will be implemented by filling out the main activities excluded from internal resources and open core activities over the next five years from external recruitment to enhance the core functionality. It is proposed to set up a skills development program to improve technical and managerial skills to ensure the use of temporary workers and their readiness for current and future positions.

The ordinary least squares (OLS) regression models only the conditional mean of the response and is computationally less expensive. Quantile regression on the other hand is more expensive and rigorous but capable of handling vectors of quantiles and outliers. Quantile regression does not assume a particular parametric distribution for the response, nor does it assume a constant variance for the response, unlike least squares regression. This paper examines the impact of various quantiles (tau vector) on the parameter estimates in the models generated by the quantile regression analysis. Two data sets, one with normal random error with non-constant variances and the other with a constant variance were simulated. It is observed that with heteroscedastic data the intercept estimate does not change much but the slopes steadily increase in the models as the quantile increase. Considering homoscedastic data, results reveal that most of the slope estimates fall within the OLS confidence interval bounds, only few quartiles are outside the upper bound of the OLS estimates. The hypothesis of quantile estimates equivalence is rejected, which shows that the OLS is not appropriate for heteroscedastic data, but the assumption is not rejected in the case of homoscedastic data at 5% level of significance, which clearly proved that the quantile regression is not necessary in a constant variance data. Using the following accuracy measures, mean absolute percentage error (MAPE), the median absolute deviation (MAD) and the mean squared deviation (MSD), the best model for the heteroscedastic data is obtained at the first quantile level (tau = 0.10).

Published: January 2023

We examine the efficiency and efficacy of the Arbitrage Pricing Theory model in explaining stock returns in the food and beverage industry. To that end, we analyze the relationship between macroeconomic variables and stock returns before and during the pandemic. In this paper, we use unexpected changes in economic growth, inflation, interest rate, exchange rate, and crude oil price as generating factors and find that these factors have come to explain stock returns movement. Using the generalized least square (GLS) technique, we study stocks from 19 firms listed in Indonesia Stock Exchange over sixteen months from 2018 to 2021. While most significant relations are negative, some are significantly positive. The significant associations suggest that the theory is supported in that estimated expected returns depend on selected generating factors. The result also shows that investors are rational because they consider these factors as systematic risks influencing their profit. Furthermore, we find that there is a difference in stock returns before and during the pandemic, with the average being greater during the pandemic. We assume that this is due to investors’ choice to seek out safe-haven assets in order to limit their exposure to losses.

Published: January 2023

After the occupation of their land by Europeans, the Australian Aboriginal and Torres Strait Islander people were expected to benefit from an education system based on that of the dominant Europeans. Gradually educators realized that Aboriginal culture has validity and strength and that all children learn differently. In this paper the characterization of the Aboriginal learner is examined and pedagogical strategies to assist in both students' learning and teachers' delivery are explored. The message that is conveyed in this paper has particular relevance to teaching mathematics to Aboriginal learners as well as to the general curriculum. It is also of considerable value in teaching non-Aboriginal students.

La crecida que se produjo el 1 de septiembre de 2021 en Les Cases d’Alcanar (Tarragona), es una de las de mayor magnitud del litoral mediterráneo occidental durante la época instrumental. Se ha realizado una reconstrucción post-evento determinando el caudal punta mediante el modelo hidráulico 2D IBER y la respuesta hidrológica de la cuenca a través del software hidrológico global HEC-HMS. Tras una lluvia de 251,9 mm en unas 3 horas, se estima que el pico fue de 159 m3·s-1 a la entrada de la población y el volumen de escorrentía fue de 1,15 hm3. El coeficiente de escorrentía alcanzó a 0,76. Gran parte del desbordamiento en el núcleo poblado fue debido a la oclusión de los drenajes transversales al torrente y a la falta de capacidad de drenaje del canal. Los datos reconstruidos se consideran de un gran valor para la planificación de estructuras en cuencas pequeñas que carecen de datos de aforo.

Mercury in Brown Booby (Sula leucogaster) Feathers from the São Pedro and São Paulo Archipelago as a Tool for Environmental Biomonitoring
Authors: Benedetti Beatriz , Hoppe Trevizani Tailisi , Montone Rosalinda Carmela , Petry Maria Virginia , Lopes Figueira Rubens Cesar
Published: January 2023

Seabirds are important bioindicators of environmental quality as their feathers contain records of metal concentration. Among the metals, mercury (Hg) is toxic, causing damage to the organism even in small concentrations. The objective of this study is to determine and evaluate the total Hg levels in brown booby feathers in the São Pedro and São Paulo archipelago (SPSPA) (0º55´02´´N; 29º20´42´´W), comparing to literature levels of metal in feathers of different Sula species in several locations from Brazil and elsewhere in the world. To determine Hg levels, the study uses the methodology of partial digestion of collected feathers, followed by the analysis by inductively coupled plasma optical emission spectrometry (ICP-OES). The average value of the Hg concentration was 2.6 ± 3.5 mg L-1, which is below the threshold for the occurrence of adverse effects due to mercury toxicity in seabirds. For the statistical analysis of comparison between sexes of the SPSPA population, and for comparison between species of the genus Sula in different places around the world, this study uses Analysis of Variance (ANOVA), followed by the Tukey test. There was no significant difference between sexes in Hg concentration. However, there was a significant difference between the compared sites, demonstrating that the SPSPA has a low Hg concentration, differing only from Daphne Island, Galapagos a region with high Hg atmospheric deposition due to its climatic conditions. Between the species of the genus Sula, the study detected a significant difference in the accumulation of Hg. The species S. leucogaster differed from the species S. granti, which is also associated with Galapagos. The other species displayed accumulation of Hg resembling that of S. leucogaster, confirming a similarity between their nourishment habits and their trophic niches. The results support future Hg monitoring programs in this important Marine Conservation Unit and Environmental Protection Area.
Urban Life in the Liao on the Eve of the Jurchen Conquests
Authors: Pursey Lance
Published: January 2023

The simultaneous existence of five urban centres labelled as ‘capitals’ in the Liao dynasty by the late eleventh century has perplexed scholars who presume that the Liao court must have resided in one of these capitals as the courts of most conventional ‘Chinese’ empires did. However, the Liao court never permanently resided in any one of these capitals; the court practised ‘imperial itinerance’, wherein they moved around according to an often loosely seasonal pattern but primarily from political expedience. This paper argues that the primary-auxiliary model of capitals does not apply to the Liao and therefore that neither Shangjing, the Upper Capital, nor Zhongjing, the Central Capital, can be considered to have been primary capitals. Rather, the Liao court exercised ‘urban ambivalence’, defined here as a selective attitude to the role of capitals in statecraft. This is done by first examining the frequency and purpose of imperial visits to the capitals, and then exploring the semantics of the capital names Upper and Central. This reassessment of Liao capitals invites us to eschew normative frameworks concerning capitals derived from Chinese empires, and highlights the explanatory potential of agency over adherence to ideological models to understand the Liao court attitude to capitals.
A Call for Self-criticism in Defending Values: From Human Rights in China to the War in Ukraine
Authors: Genoud Christelle
Published: January 2023

From the beginning of the Russian invasion, Western countries have rallied behind Ukraine and the war narrative of defending democracy against authoritarianism. Nevertheless, this binary narrative has been of limited appeal to developing countries and authors have discussed how the revival of great power competition around this narrative risks reinforcing the democratic decline. Considering these limitations, how can the academic community work to counteract a return to the kind of binary thinking that has been reanimated by the Russian invasion of Ukraine? To answer this question, I draw a parallel between responses to the war in Ukraine and how Western countries are handling the issue of human rights in China, including the emergence of a binary narrative that pits Chinese against Western visions of these rights. I argue that Western countries’ lack of self-reflectivity in defending values has hindered a genuine engagement with their own weaknesses. These weaknesses have thus been exploited by authoritarian countries. As democracy - like human rights - has been invoked as much to question oppression as to legitimate the status quo and economic interests, there is a need for scholars to scientifically engage with the geopolitical motives for defending values. We should not shy away from such research because of fears of instrumentalisation by authoritarian countries, as self-criticism will help rebuild the legitimacy and credibility that democracies increasingly lack.
ESTUDO SOBRE A FINASTERIDA COMBINADA COM MINOXIDIL
Authors: Garcia Diego Gabriel
Published: January 2023

A calvície afeta adultos de meia idade, sobretudo os homens. A causa para a queda de cabelo pode ser mediada por distúrbios hormonais, fármacos – como quimioterápicos – e doenças autoimunes. Como efeito secundário, o portador da calvície pode desenvolver problemas psicológicos e psiquiátricos. Com isto, diversas linhas de pesquisa vêm desenvolvendo métodos para retardar ou reverter a queda capilar. Os métodos mais acessíveis são o uso de princípios ativos tópicos ou orais que agem diretamente nos folículos pilosos, devolvendo a nutrição e fortalecendo os fios.Dentre esses, existe a Finasterida que é um medicamento oral indicado para controlar a queda capilar e o aumento da próstata em homens. No Brasil, não precisa de prescrição médica. No entanto, é importante se consultar com um especialista antes de começar a usar o componente. O medicamento atua como um inibidor da enzima 5-alfa-redutase, capaz de converter o hormônio testosterona, na sua forma ativa, o DHT (di-hidrotestosterona). A redução da ação dos níveis de DHT em casos de hiperplasia prostática benigna, por exemplo, ajuda a manter o tecido da próstata, a reduzir a obstrução da uretra, facilitando a eliminação da urina, além de diminuir a necessidade de cirurgias na glândula. A Finasterida é utilizada no tratamento da queda de cabelo em homens ao diminuir a quantidade do hormônio DHT (di-hidrotestosterona) no organismo. O DHT, formado a partir da testosterona, consegue atuar nos folículos capilares, promovendo a sua atrofia. A redução dos níveis da testosterona ativa, promovida pela finasterida, ajuda no crescimento capilar. Por outro lado, tem-se o Minoxidil que reduz a pressão arterial sistólica e diastólica por diminuição da resistência vascular periférica através de vasodilatação. A musculatura lisa dos vasos de resistência deve ser considerada o local de ação para o efeito relaxante do Minoxidil. No entanto, os mecanismos bioquímicos que produzem a redução da resistência periférica ainda não foram totalmente esclarecidos. Poderia ser demonstrado em estudos com animais que Minoxidil bloqueia a entrada de cálcio na membrana da célula durante a despolarização. Diversos estudos e observações sugerem que, após a administração de Minoxidil, são ativados mecanismos secundários que causam vasodilatação. Contudo, também é utilizado contra queda e enfraquecimento capilar.

Diante do exposto, o estudo objetiva revisar na literatura a importância da educação da população indígena como forma de arma para lidar com os colonizadores. Trata-se de uma revisão bibliográfica de literatura realizada através do google acadêmico, através das seguintes palavras-chave: “população indígena” e “educação”. Combinados entre si pelo operador booleano AND. Como critérios de inclusão: artigos disponíveis na íntegra, nos idiomas português, espanhol e inglês, que abordassem a temática. Como critérios de exclusão: artigos que não contemplavam o tema e estudos repetidos nas bases de dados. Emergiram as variáveis educação infantil, ensino fundamental e médio e ensino superior. Podemos perceber que os colonizadores tentaram dificultar a aprendizagem dos povos indígenas com objetivo de impor a sua cultura para eles.

Este artigo descreve as experiências vivenciadas no Estágio Supervisionado II, do Curso de Licenciatura em Computação, da Universidade do Estado do Amazonas-UEA, no Centro de Estudos Superiores de Itacoatiara - CESIT. Tendo como objetivo principal, proporcionar aos alunos os conhecimentos sobre os conceitos de funções matemáticas utilizando os softwares educacionais para a melhor compreensão e interação no processo ensino aprendizagem. A pesquisa assume uma abordagem qualitativa, pois se trata de um estudo descritivo relatando experiências na prática de estágio. A fundamentação teórica norteia-se os estudos sobre o estágio supervisionado, uso de softwares educativos e gamificação. As atividades foram elaboradas a partir da problemática observada durante o período de observação e coparticipação nas turmas do primeiro, segundo e terceiro ano do ensino médio na Escola Estadual Professora Mirtes Rosa Mendes de Mendonça Lima, com o apoio do professor supervisor de estágio, considerando as dificuldades apresentadas pelos alunos sobre as referidas problemáticas. Os participantes da pesquisa foram os alunos 1º anos do ensino médio. Diante do problema de pesquisa investigado e compartilhado sobre as dificuldades na disciplina de matemática, e diante do que foi observado, foi elaborado um plano de ação em que resultou na utilização do laboratório e a sala de aula para aplicação das atividades na plataforma Quizizz e o aplicativo GeoGebra. A plataforma aborda o ensino da matemática envolvendo a gamificação tendo como base proporcionar o espírito competitivo dos alunos, pois o site proporciona ranking dentro do jogo. O desafio consiste em que os alunos devem acertar as operações matemáticas inclusos por cartas que somente uma estaria certa, a cada acerto é mostrado na tela de ranking quantos alunos acertaram e quantos erraram a pergunta, logo após os três alunos que estão com pontuações elevadas são exibidos os nomes e a colocação. Os resultados obtidos foram gerados e discutidos com o professor supervisor em sala de aula. A utilização de tecnologia em sala de aula abre opções para se ensinar matemática ou qualquer área de conhecimento.

A paralisia cerebral descreve um grupo de desordens permanentes do movimento e postura atribuídos a um distúrbio não progressivo que ocorre durante o desenvolvimento do cérebro fetal ou infantil. Há uma grande variação nas formas como a PC se apresenta, estando diretamente relacionadas à extensão do dano neurológico, com diferentes graus de comprometimento motor e cognitivo. As alterações da parte motora incluem, problemas na marcha (como paralisia das pernas), hemiplegia (fraqueza em um dos lados do corpo), alterações do tônus muscular (espasticidade caracterizada por rigidez dos músculos) e contração involuntária dos membros. Uma das principais causas de paralisia Cerebral (PC) é a hipóxia, situação em que, por algum motivo relacionado ao parto, tanto referentes à mãe quanto ao feto, ocorre falta de oxigenação no cérebro, resultando em uma lesão cerebral. Crianças com PC que conseguem andar têm aproximadamente 36% a 82% da força muscular de crianças com desenvolvimento típico. A fraqueza muscular é frequentemente relatada como um fator importante que afeta a capacidade de andar.  Dessa forma, o presente estudo tem por objetivo identificar se há efetividade do treino de força em membros inferiores, aos pacientes pediátricos acometidos com paralisia infantil e sua melhora na marcha. Para o desenvolvimento deste trabalho, foi utilizada a pesquisa bibliográfica e qualitativa, realizada a partir na busca de base de dados: PEdro e Pubmed, nos idiomas português e inglês, entre os anos de 2018 e 2022. Foram encontrados 313 estudos e após leitura dos títulos e resumos por não se encaixarem à finalidade do estudo, de acordo com os critérios de exclusão, foram selecionados 8 estudos. Os estudos analisados nessa revisão tiveram em sua maioria resultados positivos em relação a melhora da marcha após o fortalecimento dos MMII, proveniente das intervenções aplicadas. Entretanto, alguns estudos ainda resistem ou não apoiam a eficiência das técnicas de fortalecimento para melhora da marcha em crianças com PC. Desse modo, torna-se imprescindível o aumento de comprovações científicas por meio de estudos que correlacionem a intervenção quanto ao tempo e uso de forma correta para a melhora da força e marcha de pacientes pediátricos, para que se comprove uma intervenção justificável e eficiente.

Para o concreto ser um material que apresente bom desempenho diante do processo construtivo e durante os esforços nos quais estarão submetidos durante o tempo de vida útil de uma construção, os materiais que os constitui deve ter qualidade assegurada mediante critérios normativos sobre materiais. Este artigo descreveu sobre o material concreto e sobre os seus constituintes. Além disso, obteve um traço racional de concreto com dois tipos diferentes de agregados graúdos utilizados na cidade de Passos. Durante o desenvolvimento dos trabalhos foi possível fazer uma dosagem de concreto com os traços obtidos e comparados com dois traços cujos comportamentos eram conhecidos. Ao final, pode se observar o melhor desempenho do concreto no estado fresco e endurecido quando se utilizou o diabásio.

Abstract. A cloud identification and profiling algorithm is being
developed for the multi-spectral imager (MSI), which is one of the four
instruments that the Earth Clouds, Aerosols, and Radiation Explorer
(EarthCARE) spacecraft will feature. During recent work, we noticed that the MSI response function could shift substantially among some wavelengths (0.67 and 1.65 µm bands) owing to the spectral misalignment (SMILE), in which a shift in the center wavelength appears as a distortion in the spectral image. We evaluated how SMILE affects the cloud retrieval product qualitatively and quantitatively. We chose four detector pixels from bands 1 and 3 with the nadir pixel as the reference to elucidate how the SMILE error
affects the cloud optical thickness (τ) and effective cloud droplet
radius (re) by simulating the MSI forward radiation with Comprehensive
Analysis Program for Cloud Optical Measurement (CAPCOM). We also evaluated
the error in simulated scenes from a global cloud system-resolving model and a satellite simulator to measure the effect on actual observation scenes. For typical shallow warm clouds (τ = 8, re = 8 µm), the SMILE error on the cloud retrieval was not significant in most cases (up to 6 % error). For typical deep convective clouds (τ = 8, re = 40 µm), the SMILE error on the cloud retrieval was even
less significant in most cases (up to 4 % error). Moreover, our results
from two oceanic scenes using the synthetic MSI data agreed well with the
forward radiation simulation, indicating that the SMILE error was generally
within 10 %. Generally, this negligible impact of the SMILE is true for
water surfaces, but it still needs to be investigated further for land
surfaces in future works.

Abstract. We derive an explicit (i.e. non-iterative) formula for the retrieval of the overlap function in an aerosol lidar with both elastic and Raman N2 or/and O2 channels used for independent measurements of aerosol backscatter and extinction coefficients. The formula requires only the measured, range-corrected, elastic and the corresponding Raman signals, plus an assumed lidar ratio. We assess the influence of the lidar ratio error in the overlap function retrieval and present retrieval examples.
