Authors: Liang Junhui , Xu Jia , Xie Shiwei , Cao Junming , Tan Beiping
Published: May 2022

Since lots of researches using qPCR technique have addressed gene expression in groupers, the suitable housekeeping genes are needed to obtain reliable and precise results. In this study, by using different mathematical algorithms (Genorm, normFinder, BestKeeper and comparative ΔCt method) and the comprehensive ranking software (RefFinder), the stability of seventeen housekeeping genes were assessed in eleven tissues of the hybrid grouper (Epinephelus fuscoguttatus ♀ × E. lanceolatus ♂). Results showed that the stability of housekeeping genes were various in different tissues and the newly identified housekeeping genes were likely more stable than that of commonly used. In conclusion, the expression stability of housekeeping genes showed a tissue-specific manner, and the conserved oligomeric Golgi complex subunit 5 (cog5) and peroxisomal biogenesis factor 14 (pex14) could be universally used as appropriate housekeeping genes across different tissues in hybrid grouper. The present study provides the foundation for more accurate results of qPCR assay in hybrid grouper and other groupers.

Authors: Alkhatib Mohammed Hassan , Yahiaoui Nacira , Awaja Ahmed Rawhy , Awaja Doaa Said
Published: May 2022

In this aggressive competition taking place around the world, knowledge management is recognized as the main vehicle for organizations to achieve a competitive advantage: to compete and provide higher quality and better services that satisfy customers. Linking knowledge management to service quality could make a strong contribution in convincing managers of organizations about the need to adopt knowledge management strategies. Taking these issues into account, this study introduces the pathway to service quality (SQ) with the role of knowledge management capabilities (KMC) (knowledge infrastructure capability KIC and knowledge process capability KPC) and organizational commitment (OC). This paper aims at investigating the role of KMC in enhancing the quality of service in Higher Education Institutions (HEIs) through the mediating effect of OC. Based on the analysis conducted on 352 responses from academic middle managers and teaching staff selected from HEIs of Palestine- Gaza Strip. The results exhibit significant positive influence of knowledge management capabilities on enhancing service quality, and organizational commitment partially mediates the relationship between knowledge management capabilities and SQ. These results provide new avenues for managers to enhance service quality of Education institutions using KMC at prime level; with updated technology, sufficient structure, and supportive culture, in addition to ensuring effective implementation of knowledge processes. Additionally, these capabilities will help to increase the level of commitment in organizations, which will lead to quality of service, innovation, competitive advantage and enhanced overall performance.
„Złego sługę malarze tak figurowali”. Źródła wizerunków dobrego i złego sługi oraz dobrej i złej żony z czwartego rozdziału Źwierzyńca Mikołaja Reja
Authors: Grześkowiak Radosław

“Złego sługę malarze tak figurowali” (“A bad servant was so depicted”): Sources of the Images of a Good and Bad Servant and of a Good and Bad Wife in Chapter 4 of Mikołaj Rej’s Źwierzyniec (‘The Bestiary’)

The chapter of Mikołaj Rej’s Źwierzyniec (‘The Bestiary’), entitled Jako starych wieków przypadki świeckie ludzie sobie malowali (‘As People Painted Secular Shapes from Old Times’), is a collection of epigrams accompanied by visual illustrations of various human features and vices. As proved in 1893 by Ignacy Chrzanowski, some of the pieces were inspired by Andrea Alciato’s emblems, hence the search for Rej’s sources focused on emblem literature. However, despite the evidence that Rej’s epigrams were intended as comments to illustrations, they still may be rooted in literary texts.

This article deals with the sources of four epigrams, namely, the one depicting a bad servant, a good servant, a good wife and a bad wife. The epigram Sługa dobry (IV 31, ‘The Good Servant’) may have been modeled on the popular treaty Οίκετηςsive De officio famulorum, written in 1535 by Gilbert Cousin, who described an image of a good servant, subsequently painted in French nobles’ chambers. It presented a human silhouette with a pig’s face, donkey’s ears and deer’s legs, which captured the idea of the servant being easy to feed, eager to listen and fast to follow the master’s orders. This image was widely popularized in 16th-century drawings, however none of them is known to have been familiar to Rej before 1562 and used by him as a pattern for his epigram.

Since a pig’s snout is associated with gluttony in Rej’s other texts, in the epigram Sługa dobry it is replaced by a bull’s head. The image of the snout is exploited in Zły sługa (IV 30, ‘The Bad Servant’). Rej equipped the bad servant with a wolf ’s ears – he will pretend to misunderstand orders for his own benefit, a bear’s paws –he steals, and a dog’s tail – he flatters his master.

The two epigrams presenting the images of a good wife and a bad wife, were inspired by verses that were echoed in Rej’s other works, for instance in Postylla (1557, ‘Postil’) and Żywot człowieka poczciwego (1568, ‘Life of a Virtuous Man’). The epigram Żona poczciwa (IV 32, ‘The Virtuous Wife’) alludes to Ps. 128(127):3, whereas Żona wszeteczna (IV 33, ‘The Profligate Wife’) to Prov. 11:22.

Indonesia is a country consisting of islands and oceans. The existence of ships as a means of sea transportation plays an important role in connecting between regions separated by the ocean in human distribution and logistics needs. Part of the ships that often suffers damage due to operational and corrosive environments is the hull. One of the protections for the hull is paint coating. As a protector on the ship the paint layer is thinning due to friction with water media which can cause damage to the paint layer and reduce the protection function of the ship's hull plate from corrosion. This study aims to determine the effect of the flow of seawater, fresh water and brackish water on the hull paint. This research uses an experimental method, with the experimental variables were three types of paint which are applied to the steel plate remaining from the ship's hull installation. In this study, a comparison of the paint layer was calculated before and after the specimen placement process on water variable media for 7 days with a constant flow rate. The results of this study indicate that seawater media has the highest level of depletion in the hull paint layer.

Authors:   Department of Statistics, Ekiti State University, Ado-Ekiti, Ekiti State, Nigeria, Peter Ajewole Kehinde
Published: May 2022

The ordinary least squares (OLS) method had been extensively applied to estimation of different classes of regression model under specific assumptions. However, this estimation procedure OLS does not perform well with outliers and small sample sizes. As a result, this work considered the application of the maximum likelihood method for polynomial regression model using sample sizes as against the large sample assumption in OLS. The efficiency of the maximum likelihood (ML) estimation technique was put to test by comparing its model fit to that of the OLS using some real world data sets. The results of analysis of these data sets using both methods showed that the ML outperformed the OLS since it gave better estimates with lower mean square error (MSE) values in all the four data sets considered and higher coefficient of determination (R2) values. Although, both methods resulted in overall good fit, but the ML is more efficient than the OLS because it resulted in lower MSE for small sample sizes.

Published: May 2022

Purpose - This study focuses on analyzing the role of spiritual marketing in strengthening millennial’s purchase intention at Islamic banks through brand positioning and brand personality. There are several reasons to focus on spiritual marketing as an aspect of branding, such as marketing that prioritizes spiritual values makes the brand better. It is also able to improve the brand inner-side. Moreover, there is an opportunity and great hopes that the future market segmentation of Islamic banks is not only filled by Muslim market segments, but also filled by the non-Muslim market segment. Design / methodology / approach - This research is a quantitative study, using a sample of 150 respondents in Jakarta who represent the millennial generation as the population of the study. Data analysis uses the Structural Equation Modeling (SEM) technique with the Analysis of Moment Structure (AMOS) program to test the role of spiritual marketing in strengthening millennial’s purchase intention at Islamic banks through brand positioning and brand personality. Findings - The statistical results show that brand positioning has no positive effect on purchase intention, while brand personality has a positive effect on purchase intention. This study also reveals the importance of the role of spiritual marketing as a valuable moderating dimension of brand positioning and brand personality in strengthening purchase intention. Other findings reveal that brand positioning and brand personality have mutual interventions on the purchase intention of millennials at Islamic banks. Limitations / research implications - Future research can develop a wider sample of millennials so that they can expand better results and concepts in implementing spiritual marketing as an important element in strengthening purchase intention. Originality / value - This study departs from the scarcity of research on the application of branding theory to the concept of spiritual marketing by using the dimensions of brand positioning and brand personality in influencing purchase intention.

The performance and life of a li-ion battery is affected by the working temperature of the battery, the heat generated when the battery is operating can cause problems with the battery, such as reducing its life and in the worst case an explosion will occur. This study aims to determine the economic feasibility of applying heat pipes to the disposal of thermal waste batteries for electric vehicles). Economic analysis is studied in terms of optimizing battery costs with a heat pipe cooling system against batteries without a cooling system. The process of calculating the economic value carried out includes calculating the BCR (Benefit Cost Ratio) value and NPV (Net Present Value) value. The BCR value obtained shows the number 1.28. The NPV value shows a figure of IDR 2,050,740 which exceeds the number 0. The use of heat pipes can be an alternative for managing battery thermal waste. The BCR value minimizes the level of risk from investing in a project or unit. The NPV value also shows that the project can be accepted economically and the next process can be carried out.
The role of the World Trade Organization in achieving the interests of developing countries “Egypt Case”
Authors:   Economics Department, Vice Dean Faculty of Politics &Economics, Beni-Suef University, Beni-Suef, Egypt, M. Elgayish Mosaad
Published: May 2022

The principles of the World Trade Organization (WTO) included a set of exceptions to help developing countries to speed up the process of their economic development. Therefore, the research problem focused on the extent to which developing countries benefit from these exceptions, and by applying it to the Egyptian case. The researchers used the threshold regression model to measure this benefit based on the data of the World Bank. The research concluded that most of the exports of developing countries, including Egypt, are raw materials that Industrial countries seek to innovate alternatives for them and thus do not benefit the optimum benefit from the export subsidy exception, just as the developing countries opened up to the world and entered the competition market without being qualified enough to compete. Although the WTO allowed the protection of nascent and emerging national industries in a manner that does not contradict the foundations adopted in its 1994 WTO agreement, the developing countries did not achieve the maximum benefit because they did not have the conditions for competition in the global market, and some developing countries also accepted to sign the Government Procurement Agreement Because of the political pressures that achieve the interests of the developed countries that have interests. The research recommended the need to request re-negotiations to try to extend the transitional period to allow the advancement of emerging and nascent industries in developing countries, and the importance of accelerating the upgrading of the industries of developing countries in order to be eligible to enter the global competition, in addition to the need to maintain the value of commodity and service exports and the added value in manufacturing. And the net inflows of foreign direct investment in Egypt at levels lower than the threshold in order to promote economic growth in Egypt.
ADOPTING E-COMMERCE PLATFORMS IN ABIDJAN (CÔTE D’IVOIRE) BASED ON IMPULSIVE BUYING BEHAVIOUR THEORY
Authors: Yoboué Wiliam Kouame
Published: May 2022

Purpose: This study concentrated on the adoption of e-commerce platforms base on impulsive buying behaviour, using technology for sustainable development of governments’ institutions, small medium enterprises and individual consumers or customers in Abidjan.

Methodology: The research adopted a Quantitative approach and the data collection instrument used in this study is the survey questionnaire. The focus in this research was on the buyer (the individual who is involved in any buying and selling of goods over the internet). Therefore, the set of questionnaires was administered to users of e-commerce in Abidjan-Cote d’Ivoire. The survey questions were developed based on an adaptation process of e-commerce envisaged in our proposed framework. Data was gathered from April, 2020 through September, 2020 and convenient sampling technique was used. In this quantitative case study, a total of 523 questionnaires were administered randomly among users of e-commerce in Abidjan. The users cut across all walks of life and private organizations. The organizations within a particular sector were randomly selected but with fair coverage and representation with only one commonality, i.e. they’re all having some form of secular education at a level. Out of the 523 questionnaires distributed, 500 of the questionnaires were returned which represents 95.6% of the total number administered in this particular study.

Findings: As regards to the results, Impulsive buying behavior constructs have a significant relationship with Ecommerce adoption strategy with behavioral intention to adopt Ecommerce as a moderator. Unfortunately, no significant relationships were found between social influence, perceived awareness/education and experience with respect to behavioral intention to adopt e-commerce. Therefore, most of the model fit indices in this research obtained after an extensive modeling and improvements with covariance was however below the optimal requirement. It is concluded that this model is not a very good fit to describe the factors affecting the behavioral intention to adopt e-commerce.

Recommendation: This model can be recommended for more research in the future because the proposed model requires further testing and thorough empirical validation.

Authors:   Bicol Unversity, Arena Eliza Ann A. , Bernal Mae Breech R. , Imperial Jazzlyn T.
Published: May 2022

Endophytic fungi were isolated from Capsicum annuum (siling labuyo) from three ecological zones in the province of Albay, Philippines and were identified through morpho-cultural characteristics and by molecular analysis of the internal transcribed spacer (ITS) region of the 18S ribosomal DNA. Eight fungal endophytes were isolated from the leaves and fruits. Seven were identified as Colletotrichum gloeosporioides, Lasiodiplodia pseudotheobromae, Nigrospora sphaerica, Guignardia mangiferae, Coprinopsis cinerea, Colletotrichum siamense and Colletotrichum truncatum while one remained unidentified. The extracted metabolites from the isolates were then screened for their antibacterial activities at 1,000 µg/mL. Among the fungal isolates, C. cinerea was found to be the most active against Staphylococcus aureus and Escherichia coli with zones of inhibition (ZOI) of 16.00 ± 1.00 and 17.00 ± 1.53 mm, respectively. Phytochemical screening showed that C. cinerea produced a variety of secondary metabolites such as flavonoids, alkaloids, terpenoids and quinones. The other fungal endophytes were also found to synthesize various secondary compounds that may be responsible for their antibacterial activities.

A reprodução social camponesa se constitui no universo da subordinação da terra ao capital, representando um paradoxo que é próprio do capitalismo. Inúmeras são as estratégias dessa reprodução, entre elas, a família, o trabalho e a religiosidade, características que, no decorrer deste trabalho, foram identificadas na comunidade do Cravo, localizada no Nordeste paraense, uma região marcada por conflitos em função do avanço do agronegócio do dendê. Assim, a partir deste recorte espacial, buscamos discutir como o campesinato se reproduz na Amazônia, frisando a importância da terra e do território e, quais as especificidades que carrega consigo.
Um exercício metodológico para a detecção de apropriações privadas de terras públicas federais: o caso do município de Pacajá, Pará
Authors: Terence Marcelo Fernando
Published: May 2022

O presente artigo discute a formação da propriedade capitalista da terra no Brasil a partir da apropriação privada de terras públicas federais. A análise foi feita a partir de dados sobre a malha fundiária do município de Pacajá/PA e de um caso específico de apropriação particular em terras públicas nessa localidade. O objetivo principal é trazer uma reflexão sobre a continuidade de um verdadeiro caos fundiário e construir uma metodologia de verificação dessas apropriações que possa ser aplicada em qualquer parte do país, com a utilização dos dados oficiais disponíveis. Esses dados sobre a malha fundiária só existem atualmente porque uma série de normativas e instrumentos tecnológicos foram elaborados e implementados pelo Estado brasileiro nas últimas décadas. Não obstante, o descontrole sobre a utilização privada das terras públicas permanece. O estudo do caso do complexo de fazendas Gramane, localizado no município estudado, trará luz sobre a principal força de resistência às formas ilegais de apropriação de terras públicas, qual seja, a atuação de movimentos sociais de luta pela terra.

A pesquisa fala o modo como se deu a formação de um assentamento do município de Goiás. Investigou-se o processo que fez surgir o assentamento e as condições de moradia e de vida das famílias existentes nesse espaço, bem como a territorialização das famílias que moram nele, desde aquelas que participaram do processo de conquista de terra até aquelas que, posteriormente, acessaram os lotes do assentamento por meio de transações como compra e concessões. A criação de assentamentos rurais de reforma agrária é fruto de ações e políticas públicas contraditórias e reflete interesses conflituosos. Mesmo assim, considerando todos estes aspectos de contradições e conflitos de interesses, os assentamentos podem se constituir em referência para a efetivação do acesso à terra alterando a situação fundiária em municípios como e estudado. Percebemos que a convivência entre os moradores nas unidades produtivas é permeada desses conflitos de como se procedeu o acesso e a permanência no assentamento.

O modelo socioeconômico vigente culmina em um desenvolvimento insustentável que coloca interesses econômicos à frente das populações humanas,  da fauna e flora que servem como subsistências desses povos. Os conflitos socioambientais são respostas de comunidades vulnerabilizadas para restabelecimento de justiça ambiental. Nesses espaços sociais é possível observar violações de direitos, diretamente, através dos abusos das empresas e, indiretamente, através do silêncio da mídia e autoridades públicas. O estudo teve como objetivo realizar mapeamento de conflitos socioambientais no território do Complexo Industrial de Suape (CIPS) e expor as desigualdades e injustiças nesta região em prol do desenvolvimento insustentável. Trata-se de estudo descritivo de abordagem qualitativa. Foram utilizados dados secundários do banco de dados “mapeamento de conflitos socioambientais no território de Suape”, adequando-os aos critérios do Mapa Global de Justiça Ambiental (Ejatlas). Foi identificado conflitos socioambientais, relacionados a problemáticas em torno da propriedade da terra/moradia e a violência contra moradores residentes nas comunidades de Suape. Foi evidenciado que os conflitos socioambientais existentes são movimentos antigos, porém, historicamente silenciados.  Dar visibilidade aos conflitos socioambientais existentes pode contribuir para luta socioambiental dessas comunidades.

Prescribing techniques of KwaZulu-Natal homoeopathic practitioners for paediatric patients
Authors:   , Khumalo Mzwandile
Published: May 2022

Introduction The homoeopathic practice is polarised between the theoretical foundations of traditional homoeopathy and the contemporary practices as employed by homoeopathic practitioners in their respective practices. To date, the process of case taking and prescribing techniques for paediatric patient in homeopathy is largely unexplored and little is understood about its reliability. Despite a plethora of research showing the effectiveness of homoeopathic remedies in the treatment of paediatric patients. Little is known about the different skills and techniques used by homoeopathic practitioners in prescribing for paediatric patients. The objectives of this study were to expand the database of knowledge regarding the prescribing techniques of homoeopathic practitioners when treating children, by investigating practitioners’ diagnostic framework in the treatment of paediatric patients. The study was guided by the questions: to what theoretical and applied foundations do homoeopaths base their prescription for paediatric patients? Methodology A qualitative, explorative, descriptive and contextual design was employed. Qualitative research in this study was considered the most appropriate method to gain an in-depth understanding of the prescribing techniques of homoeopathic practitioners. Convenience sampling was used to recruit a minimum of 10 and maximum of 15 potential research participants from qualified and registered homoeopathic practitioners, but the sample size was only determined once data saturation was obtained. The study population were experienced homoeopathic practitioners with a minimum of five(5) year experience in practice and treating children. The data was collected and analysed using Tesch’s eight-step procedure. Results Results obtained from this study showed that the study cohort had experienced challenges in the treatment of paediatric patients in their early practice, such challenges stem from the inability of children to sensationally express their symptoms. Homoeopathic practitioners have to rely on their own observation, physical examination and secondary information from the parent. Homoeopathic practitioners further added that homoeopathy is perceived as safe by the parents. Though homoeopathic practitioners foreground their practice on individualization principle, majority of the study groups reported that their focus is on the constitutional prescribing whilst also acquiring an in-depth knowledge of the child’s past medical history, pregnancy and labour, physical symptoms and own observation of the child. Furthermore, the practitioners reported that general symptoms of the paediatric patient are very important as they are less subjected to interpretation.

Purpose. By studying the relationship between vocational education and social and economic development, this paper further clarifies the internal relationship between them, and then puts forward the strategies for vocational education to adapt to social and economic development.

Results. Through the investigation and analysis of the problems between vocational education and socio-economic development, we conclude that the strategies to enhance the ability of vocational education to adapt to socio-economic development are: firstly, we should strengthen the reform of vocational education serving socio-economic development, improve the vocational education and training system, pay attention to the cultivation of students’ key employability, and actively and deeply integrate the development of regional economy. Secondly, we should carefully analyze the uncoordinated and incompatible problems between vocational education and economic development, and solve them as soon as possible. Finally, the government should evaluate the ability of vocational education to promote social and economic development, strengthen the macro control of vocational education, give play to the important role of enterprises in the process of vocational education, introduce big data management, and set a good direction for vocational education, so as to support the sustained and rapid development and progress of the economy.

Scientific novelty. This paper carefully analyzes the related problems between vocational education and social and economic development. In view of the combing and analysis of these problems, this paper obtains the relevant strategies to enhance the ability of vocational education to adapt to social and economic development, and points out the direction for the cultivation of technical and skilled talents that that will promote economic development.

Practical value. Through the investigation and analysis of the relationship between vocational education and social and economic development, we find that there are some uncoordinated and incompatible problems between the current situation of vocational education and economic growth. By carefully combing and analyzing these problems, we can establish the direction of vocational education reform and development, and combined with the development trend of modern economic system, draw the strategy of how vocational education can adapt to social and economic development.
Limitations of a proposed correction for slow drifts in decision criterion

Published: May 2022

Trial history biases in decision-making tasks are thought to reflect systematic updates of decision variables, therefore their precise nature informs conclusions about underlying heuristic strategies and learning processes. However, random drifts in decision variables can corrupt this inference by mimicking the signatures of systematic updates. Hence, identifying the trial-by-trial evolution of decision variables requires methods that can robustly account for such drifts. Recent studies (Lak’20, Mendonça‘20) have made important advances in this direction, by proposing a convenient method to correct for the influence of slow drifts in decision criterion, a key decision variable. Here we apply this correction to a variety of updating scenarios, and evaluate its performance. We show that the correction fails for a wide range of commonly assumed systematic updating strategies, distorting one’s inference away from the veridical strategies towards a narrow subset. To address these limitations, we propose a model-based approach for disambiguating systematic updates from random drifts, and demonstrate its success on real and synthetic datasets. We show that this approach accurately recovers the latent trajectory of drifts in decision criterion as well as the generative systematic updates from simulated data. Our results offer recommendations for methods to account for the interactions between history biases and slow drifts, and highlight the advantages of incorporating assumptions about the generative process directly into models of decision-making.

Abstract. A record-breaking severe ozone (O3) pollution episode occurred in the Pearl River Delta (PRD) in early Autumn 2019 when PRD was under the influence of a Pacific subtropical high followed by Typhoon Mina. In this study, we analyzed the effects of meteorological and photochemical processes on the O3 concentration in PRD during this episode by carrying out the Weather Research Forecast-Community Multiscale Air Quality (WRF-CMAQ) model simulations. Results showed that low relative humidity, high boundary layer height, northerly surface winds and strong downdrafts were the main meteorological factors contributing to O3 pollution. Moreover, delayed sea breezes that lasted into the night would transport O3 from the sea back to land and resulted in secondary O3 maxima at night. In addition, O3 and its precursors stored in the residual layer above the surface layer at night can be mixed down to the surface in the next morning, further enhancing the daytime ground-level O3 concentration the following day. Photochemical production of O3, with daytime average production rate of about 7.2 ppb/h, is found to be the predominate positive contributor to the O3 budget of the boundary layer (0–1260 m) during the entire O3 episode; while the horizontal and vertical transport fluxes are the dominant negative contributors. This O3 episode accounted for 10 out of the yearly total of 51 days when the maximum daily 8-h average (MDA8) O3 concentrations exceeded the national standard of 75 ppb in PRD in 2019. Based on these results, we propose that the enhanced photochemical production of O3 during the episode is a major cause of the most severe O3 pollution year since the official O3 observation started in PRD in 2006. Moreover, since this O3 episode is a synoptic scale phenomenon covering the entire eastern China, we also suggest that the enhanced photochemical production of O3 in this O3 episode is a major cause of the extraordinary high O3 concentrations observed in eastern China in 2019.

Abstract. Aerosol particles in the atmosphere interact with solar radiation through scattering and absorption. Accurate aerosol optical properties are needed to reduce the uncertainties of climate predictions. The aerosol optical properties can be obtained via optical modeling based on the measured particle size distribution. This approach requires knowledge or assumptions on the particle refractive index and shape. Meanwhile, integrating nephelometry provides information on the aerosol scattering properties directly. However, their measurements are affected by angular non-idealities, and their data need to be corrected for angular truncation and illumination to provide the particle scattering coefficient. We performed an extensive closure study, including a laboratory and a simulated experiment, aiming to compare different nephelometer angular truncation and illumination corrections (further referred to as “angular corrections”). We focused on coarse-mode irregularly shaped aerosols, such as mineral dust, a worldwide abundant aerosol component. The angular correction of irregular particles is found to be only ∼2 % higher than the angular correction of volume-equivalent spheres. If the angular correction is calculated with Mie theory, the particle size distribution is needed. Our calculations show that if the particle size distribution is retrieved from optical particle spectrometer measurements and the irregular shape effect is not considered, the angular correction can be overestimated by about 5 % and up to 22 %. For mineral dust, the traditional angular correction based on the wavelength dependency of the scattering coefficient seems more accurate. We propose a guideline to establish the most appropriate angular correction depending on the aerosol type and the investigated size range.

Abstract. W.A.T.E.R. stands for Workshop on Advanced measurement Techniques and Experimental Research. It is an initiative started in 2016 in association with the Experimental Methods and Instrumentation (EMI)
committee of the International Association for Hydro-Environment Engineering and Research (IAHR) aimed at advancing the use of experimental techniques in hydraulics and fluid mechanics research. It provides a structured approach for the learning and training workshop series to postgraduate students (aiming specifically
at doctoral students), young researchers, and professionals with an
experimental background in fluid mechanics. It offers an opportunity to
learn about state-of-the-art instrumentation and measurement techniques and
the latest developments in the field by partnering with manufacturers. W.A.T.E.R. brings together academics, instrumentation manufacturers and
public sectors in a structured setting to share knowledge and to learn from
good practices. It is about training people who already have a certain knowledge and skill level but who need to go deeper and/or wider in the field of measurement and experimental research.

Abstract. Landfast ice is a common coastal feature in the Arctic Ocean and around the Antarctic continent. One contributing and stabilizing mechanism is the grounding of sea ice ridges in shallow water. Recently, a grounding scheme representing this effect on sea ice dynamics was developed in order to improve the simulation of landfast ice by continuum-based sea ice models. This parameterization assumes that the ridged keel thickness is proportional to the mean thickness. Results demonstrated that this simple parameterization notably improves the simulation of landfast ice in many regions such as in the East Siberian Sea, the Laptev Sea and along the Alaskan coast. Nevertheless, a weakness of this approach is that it is based solely on the mean properties of sea ice. Here, we extend the parameterization by taking into account subgrid-scale ice thickness distribution and bathymetry distribution, which are generally non-normal, and by computing the maximum seabed stress as a joint probability interaction between the sea ice and the seabed. The probabilistic approach shows a reasonably good agreement with observations and with the previously proposed grounding scheme while potentially offering more physical insights into the formation of landfast ice.
