Authors: ESTOA PÉREZ ABEL
Published: August 2021

La Ley 24/2013, de 26 de diciembre, del sector eléctrico, regula un
nuevo modo de suministro, e introduce novedades en la actividad de comercialización.
Sobre esto último destacan las obligaciones exigibles a las empresas de comercialización.
En particular, la Ley 24/2013 aclara que el comercializador deberá
abonar al distribuidor los peajes devengados por el ejercicio de su actividad, incluso
en caso de impago del consumidor, cliente final, bajo amenaza de sanción al comercializador.
También son relevantes las nuevas obligaciones sobre protección del consumidor
que recaen sobre el comercializador. Entre los derechos de los consumidores
figura la posibilidad de someter controversias entre los clientes finales personas
físicas y los operadores al Ministerio de Industria, Energía y Turismo (MINETUR).

The Law 24/2013, of 26 December 2013, regarding the electricity
sector, establishes a new system of supply, and a new regime for the suppliers.
With regard to the latter, new obligations to suppliers must be highlighted. The Law
24/2013 establishes that the supplier must pay to the distributor the corresponding
tariffs even if the final costumer has failed to pay the bill, with the menace of an
administrative sanction to be imposed to the supplier. New obligations regarding
costumer protection are also very relevant. Among the new rights regarding
costumer protection we must point out the action before the Ministry of Industry,
Energy and Tourism (MINETUR), in case of dispute with the operator.

SIGNATURE VERIFICATION USING SIAMESE NEURAL NETWORK ONE-SHOT LEARNING
Authors: VAROL ARISOY Merve
Published: August 2021

With the acceleration of digitalization in all areas of our lives, the need for biometric verification methods is increasing. The fact that biometric data is unique and biometric verification is stronger against phishing attacks compared to password-based authentication methods, has increased its preference rate. Signature verification, which is one of the biometric verification types, plays an important role in many areas such as banking systems, administrative and judicial applications. There are 2 types of signature verification, online and offline, for identifying the identity of the person and detecting signature forgery. Online signature verification is carried out during signing and temporal dynamic data are available regarding the person's signature. Offline verification is applied by scanning the image after signing, and this verification is limited to spatial data. Therefore, the offline signature verification process is considered a more challenging task.
In this study, offline signature verification, independent of the writer, based on One-Shot Learning, was performed using Siamese Neural Network. Due to the fact that the Deep Convolution Neural Network requires a large amount of labeled data for image classification, real and fake signature distinction has been achieved by using the One-Shot Learning method, which can perform a successful classification by using less numbers of signature images. As a result of the experiments conducted on signature datasets, using the Siamese architecture, the proposed approach achieved percentage accuracy of 93.23, 92.11, 89.78, 91.35 verification in 4NSigComp2012, SigComp2011, 4NSigComp2010 and BHsig260 respectively.
A Theoretical and Experimental Approach to E-pH Diagram for the Niobium-Water System
Authors: Santandrea Rodney , Brasil Simone L.D.C. , Reznik Leila Y. , de Carvalho Ladimir J. , de Miranda Luiz Roberto M.
Published: August 2021

Potential-pH (E-pH) diagrams are usually built from thermodynamic databases available in the literature or from specific software. However, depending on the conditions and the chemical species defined for elaborating a diagram, they may present completely different immunity, passivation, and corrosion domains. In order to obtain a result closer to a real system, experimental E-pH diagrams can be built from polarization curves obtained in the evaluated conditions. This work discloses the construction of a diagram for the Nb-H2O system at 25°C from theoretical study and the specific selection of chemical species in the solutions through computer simulations. The polarization curves for the construction of the experimental diagram were gathered without the use of buffer solutions and under pH monitoring in the solution bulk throughout all assays. The methodology proposed was considered adequate because, from experimental data, a final result compatible with the classic diagram for the Nb-H2O system and the excellent corrosion resistance of niobium in aqueous media were achieved.

Factors Influencing Farmer’s Choice of Crop Production Response Strategies to Climate Change and Variability in Narok East Sub-county, Kenya
Authors: J. Kinuthia Kelvin , Inoti Shadrack K. , Nakhone Lenah
Published: August 2021

Climate change is considered one of the most serious threats to sustainable development in the world. As a sector, agriculture is very dependent on climatic conditions, which makes it extremely vulnerable to the impacts of climate change and variability. The semi-arid areas of the world are especially more vulnerable to the impacts of climate change and variability. The purpose of this study was to determine how farmers adapt to changing climate in Narok East, and determine the factors that influence their choice of response strategies. Data was collected from 223 household heads using a semi-structured questionnaire. Data was analysed using descriptive statistics to determine how farmers adapt to climate change and variability while Principal Component Analysis and a multivariate probit model were used to assess the factors that influence the choice of response strategies. The results showed that early planting, increased use of manure, use of terraces, increased use of inorganic fertilisers, and planting short season crops were the most widely used strategies while the least used were planting agroforestry trees, crop diversification and irrigation. Results of the multivariate probit model showed that the age of the household head, total household size, level of education of the household head, noticing changes in mean annual rainfall and onset of rains, receiving weather information, and the land tenure system were all significant factors that influence the choice of the response strategy. This study, therefore, recommends boosting more education and climate change awareness for the farmers of Narok East Sub-county.
Socio-Economic Factors of Small Hydropower and Biogas Plants and their Implications for Rural Energy Poverty Alleviation in Kirinyaga, Kenya
Authors: W. Njiru Christine , Letema Sammy C. , Maingi Simon. M.
Published: August 2021

Energy is essential for sustainable development and for improving the socio-economic welfare of a community. Sub-Saharan Africa suffers from severe rural energy poverty and minimal access to modern energy services. Adoption of renewable energy technologies is often viewed as a way to alleviate rural energy poverty, but uptake is slow. Socio-economic factors, mainly household income, electricity access, fuels used for cooking, and land tenure, influence adoption of renewable energy technologies. This paper assesses the contribution of small hydropower and biogas technologies in alleviating rural energy poverty in Kirinyaga County, Kenya, where the majority of the population relies on traditional sources of energy. A case study research design was used, with a sample size of 178. Data was collected using a questionnaire survey, the review of project documents, and interviews. Five indicators were used to assess energy poverty. The results indicate medium to low energy poverty and energy stacking; with reliance on traditional sources of energy. Socio-economic factors influence adoption of SHP and biogas. Therefore, adoption of renewable energy technologies does not alleviate rural energy poverty because SHP and biogas are used to supplement rather than replace the use of traditional fuels.
Analysis of Aquifer Pumping Test Data to Determine Deep Groundwater Security in Southeastern Bangladesh
Authors: Zahid Anwar , Islam Farhana , Rashidul Hassan M. , Islam Kamrul , Ahmed Nur
Published: August 2021

In southeastern Bangladesh, where water quality in the upper aquifers is a serious constraint, future development will likely be confined to deep fresh groundwater. Owing to the importance and pervasive use of deep groundwater, the sustainability of water use has received extensive attention. However, excessive extraction from deep aquifers may pose a threat to the storage as well as the quality of water due to the high susceptibility to salinization and arsenic contamination from upper aquifers. Hence, determining the extension of aquifer units and the characterizing aquifer sediments are very important to ensure sustainable development and management of limited fresh groundwater resources. The study area extends over six districts of the southeastern coastal region of Bangladesh. In order to assess and monitor deep fresh groundwater potential in the study area, aquifer pumping tests were performed at six locations with up to 72 h of constant-discharge prior to recovery. Different methods were used to analyze the drawdown and recovery data considering aquifers as confined or leaky-confined. Based on transmissivity values it was found that the studied deep aquifers have moderate to high potential for potable water supply. However, this deep fresh groundwater may not be safe for a longer period where upper aquifer units contain saline groundwater and where there is no significant aquitard encountered above or below the deep aquifer. Irrigation extraction of the deep groundwater is not recommended.

Consequences of temporary work and job insecurity in four European countries

Consequences of temporary work and job insecurity in four European countries

Hans De Witte, Katharina Näswall, Antonio Chirumbolo, Sjoerd Goslinga, Johnny Hellgren & Magnus Sverke, Gedrag en Organisatie, volume 17, June 2004, nr. 3, pp. 163-186.

This contribution analyzes whether temporary work and (the subjective perception of) job insecurity are associated with a reduction in job satisfaction and organisational commitment, as suggested in the literature. Furthermore, an interaction between temporary work and job insecurity is tested. Data from four European countries (Belgium, the Netherlands, Italy and Sweden) are used to test the robustness of the hypotheses. Results show that temporary work is not associated with a reduction in job satisfaction and organisational commitment. Job insecurity, however, is associated with a lower score on both outcome variables, as hypothesized. In two countries, an interaction was found: job insecurity was associated with a reduction in job satisfaction and organisational commitment, though only among workers with a permanent contract. These results suggest a violation of the psychological contract for this specific category of workers.

About the role of positive and negative emotions in managers' well-being: A study using the Job-related Affective Well-being Scale (JAWS)

W. Schaufeli & W. van Rhenen, Gedrag & Organisatie, Volume 19, November 2006, nr. 4, pp. 323-344

Generally speaking, emotions are classified using two dimensions: arousal and pleasure. The Job-related Affective Well-being Scale (JAWS), a self-report questionnaire that is used to assess emotions at work, also uses these two dimensions. The current study among 815 managers has two aims. The first aim is to introduce and validate the Dutch version of the JAWS. It appears that the original 30-item version of the JAWS can be reduced to 12 items, without significant loss of information. Furthermore, the predictive validity of the JAWS is illustrated by the fact that positive emotions are negatively related to duration and frequency of future absenteeism of managers. Secondly, a model that assumes that positive and negative emotions play a different role in manager's well-being is successfully tested. Negative emotions play a key role in a stress process that may lead to burnout and health complaints, whereas positive emotions play a key role in a motivational process that may lead to employee engagement and positive attitudes towards the organization.

Validation of the Dutch Core Self-evaluations Scale

Validation of the Dutch Core Self-evaluations Scale

I.E. de Pater, S. Schinkel & B.A. Nijstad, Gedrag & Organisatie, volume 20, maart 2007, nr. 1, pp. 82-100

In this article we investigated the reliability and validity of the Dutch version of the Core Self-evaluations scale (CSES, Judge, Erez, Bono & Thoresen, 2003). Research into the English version has shown that CSE is a valid construct, consistently correlating with important work related criteria such as work satisfaction and work performance. Because of the relevance of these findings, we developed a Dutch version of this scale (NCSES). Results from four different studies (total N = 1389) showed that the NCSES is internally consistent, has a high test-retest reliability and has the predicted factor structure. Additionally, the convergent and divergent validity of the NCSES are high, and the NCSES correlates with important work outcomes, such job characteristics, job performance, and affective outcomes. It can be concluded that the NCSES is a valuable and effective instrument for applied psychological research.

Work characteristics, well-being and organizational performance: an organizational-level test of the happy-productive worker hypothesis

T.W. Taris, P.J.G. Schreurs, K.J.L. Eikmans & P. van Riet, Gedrag & Organisatie, volume 21, March 2008, pp. 3-18.

The present study examined the associations among job characteristics (demands and control), worker well-being (satisfaction and exhaustion) and indicators of organizational performance (efficiency, absence rates, and client satisfaction) among 66 Dutch home care organizations. Based on previous research, we expected that demands would relate negatively and control would relate positively to well-being, and that positive well-being would be positively related to performance. Covariance structure modeling revealed that the expected relationships among job characteristics and well-being were largely confirmed. Further, satisfaction was positively related to client satisfaction; exhaustion was negatively related to client satisfaction and positively to absence; and exhaustion was negatively related to organizational efficiency. We conclude that more theorizing and more longitudinal research on the association between worker well-being and organizational performance is imperative to add to our understanding of this relationship.

Diversity and leadership: transformational leadership and its role in managing diversity

G. De Vries & A.C. Homan, Gedrag & Organisatie, volume 21, August 2008, nr. 3, pp. 295-309

The effect of diversity on performance in work-groups can both be positive and negative. The social categorization perspective assumes a negative effect because members of a diverse work-group are more positively inclined towards members who are similar to them than to members who are dissimilar. In contrast, the information/decision-making perspective states that people who are not alike benefit from an extended network and variety in perspectives. We argue that leadership may be very important in profiting from the positive effects and diminishing the negative effects of diversity. By integrating the dimensions of transformational leadership (Burns, 1978; Podsakoff, Mackenzie, Moorman & Fetter, 1990) with the categorization-elaboration model of Van Knippenberg, De Dreu and Homan (2004) we describe how leaders can make teams profit from their diversity. Practical and theoretical suggestions are given.

Learning agility as metacompetency: Developability and career outcomes

N. Dries, T. Vantilborgh, R. Pepermans & L. Venneman, Gedrag & Organisatie, volume 21, November 2008, nr. 4, pp. 365-385

The current study let supervisors rate subordinates in terms of learning agility and focused on two research questions: (1) is learning agility developable; and (2) in what way does learning agility manifest itself in the workplace and in the careers of individuals? As regards the first research question, we found no effect of age and work experience on learning agility; we did, however, find effects of career variety and educational level. As for the second research question, we saw our hypotheses largely confirmed. Learning agility was found to be a significant predictor of on-the-job learning and performance rating. As for promotions received however, we did not find full support for the hypothesized relationships with learning agility. Interestingly, the data demonstrated that the career variety of the rated subordinates was rather low, implying that their motivation to actively look for learning experiences outside of certain geographical, organizational and functional boundaries was low, regardless of their learning agility – it thus appears that the ideal type of the flexible, 'boundaryless' career is not yet a common reality.

Kwaliteitsstandaarden voor de ontwikkeling van instrumenten voor het evalueren van empowerment
Authors: Steenssens Katrien , Van Regenmortel Tine , Schalk René
Published: August 2021

Dit artikel gaat in op de vraag aan welke theoretische vereisten moet worden voldaan bij de ontwikkeling van instrumenten voor het evalueren van empowerment. Een gerichte literatuurstudie en een kritische reflectie op bestaande meet- en evaluatie-instrumenten resulteerden in het formuleren van vijf kwaliteitsstandaarden. In de empirische fase ging het in de eerste plaats om het nagaan of de toepassing van deze theoretische kwaliteitsstandaarden in de praktijk van instrumentontwikkeling haalbaar is: leiden ze tot een instrument en is dit instrument toepasbaar? De concrete focus van deze empirische toets lag op empowerment op het niveau van een organisatie, hetgeen betekent dat instrumenten werden ontwikkeld om in kaart te brengen hoe 'empowering' organisaties zijn voor hun medewerkers én hoe 'empowered' ze zijn in hun sociale omgeving. Deze instrumentontwikkelingstrajecten vonden plaats in een openbare en in een private eerstelijns welzijnsorganisatie in Vlaanderen. Het resultaat onderschrijft de haalbaarheid van de geformuleerde kwaliteitsstandaarden voor instrumentontwikkeling. De concrete uitwerking geeft meteen een overzicht van datgene waarover het gaat wanneer een organisatie zichzelf als een 'empowering' en 'empowered' organisatie wil evalueren en versterken.

Published: August 2021

Het realiseren van diversiteit in organisaties start met de instroom van nieuwe medewerkers en het implementeren van selectieprocedures die vrij zijn van discriminatie. Deze studie onderzoekt de mate waarin sollicitanten zonder en met een visueel stigma (nl. een wijnvlek of een tattoo) kans hebben om uitgenodigd te worden voor een vervolggesprek. Op basis van theorieën over categorisatie en informatieverwerking verwachtten we dat visuele stigma's zoals wijnvlekken en tattoos leidden tot discriminatie en dat dit meer uitgesproken was voor de controleerbare stigma's (zoals tattoos) dan voor de aangeboren stigma's (zoals wijnvlekken). In een experimentele studie beoordeelden 115 HR-studenten die deelnamen aan een HR-business game, video-cv's van kandidaten met en zonder visueel stigma. De resultaten toonden dat de kans om uitgenodigd te worden 4.29 keer kleiner was voor een sollicitant met een zichtbare tattoo dan voor een even geschikte sollicitant zonder visueel stigma, en dat deze 3.21 keer kleiner was voor een sollicitant met een zichtbare tattoo dan voor een even geschikte sollicitant met een zichtbare wijnvlek. Er was geen verschil in kans op uitnodiging voor de sollicitant zonder een visueel stigma in vergelijking met de sollicitant met een wijnvlek als visueel stigma. Zelfs in tijden van arbeidsmarktschaarste zijn zichtbare tattoos enigszins taboe. Wethouders en organisaties zouden hier rekening mee kunnen houden door niet alleen sollicitanten met een oncontroleerbaar visueel stigma (zoals een wijnvlek) maar ook sollicitanten met een controleerbaar visueel stigma (zoals een tattoo) beter te beschermen tegen discriminatie.

Onderzoek naar consignatiediensten is schaars en inzicht in de kenmerken en ervaring van consignatiediensten is beperkt. Dit onderzoek geeft een overzicht van de kenmerken van consignatiediensten en van de wijze waarop werknemers dergelijke diensten ervaren. Daarnaast is de relatie onderzocht tussen enerzijds consignatiekenmerken en -ervaringen en anderzijds vermoeidheid en slaapproblemen. Data werden in 2017 verzameld door middel van een online vragenlijst die werd uitgezet onder een grote steekproef van werknemers uit verschillende branches. De steekproef bestond uit ruim 2000 Nederlandse werknemers die in hun werk werden blootgesteld aan consignatiediensten. De resultaten laten zien dat de meeste werknemers regelmatig tot vaak opgeroepen worden tijdens consignatiediensten, en dat deze consignatiediensten door de meerderheid als behoorlijk ongunstig ervaren worden. Hiërarchische regressieanalyses laten zien dat vermoeidheid en slaapproblemen sterker gerelateerd zijn aan negatieve ervaringen van consignatiediensten dan aan blootstelling aan objectieve kenmerken van deze diensten (zoals de frequentie van consignatiediensten of de hoeveelheid en duur van de oproepen). Samenvattend wijst deze studie op een hoge prevalentie van ongunstige ervaringen van consignatiediensten. In het verlengde hiervan kan geconcludeerd worden dat zelfs consignatiediensten met een lage frequentie van oproepen een risicofactor kunnen vormen voor vermoeidheid en slaapproblemen.

POTENTIAL FOR REPLACEMENT OF PORTLAND CEMENT BY CERAMIC RESIDUE IN THE SOIL-CEMENT MIXTURE FOR APPLICATION IN PAVING LAYER
Authors: Albino de Sousa André , Santos da Silva Cinthya , Arruda dos Santos Robson , Amador de Abreu Alexandra , De Souza Dias Leonardo
Published: August 2021

In 2018, of a total extension of 87,563 kilometers of road network, only 34.2% of the total presented satisfactory conditions to users. One of the main reasons for this scenario is linked to the high cost of maintenance, including the need for soil stabilization, since the composition of the pavement layers is directly linked to its resistance and durability. In this scenario, the chemical stabilization technique with soil-cement emerges as an alternative for using the soil, which initially did not present corresponding parameters for the respective use. However, the growing demand for replacement of Portland Cement in engineering services, due to the carbon dioxide levels released into the atmosphere during its production, has supported research that deals with the substitution of binder by waste generated by the production sectors, namely, red ceramic waste from the ceramic block industry. This research aims to evaluate the carrying capacity of soils stabilized with cement and the partial replacement by red ceramic waste. Soil characterization tests were carried out, which provided parameters for the dosage of the materials, and subsequent performance of the compaction, expansion and penetration tests. Based on the need to stabilize the soil classified as clayey, group A-7-6, and susceptible to great variation in volume, the addition of 13% by weight of Portland Cement to the mixture was evaluated and subsequent replacement of the binder in percentages of 20 and 30%. The results demonstrated a reduction in specific mass by increasing the substitution by RCR (Red Ceramic Residue), and also for the expansion presented by the compounds. The CBR test evaluated the percentage of 20% replacement as the one with the highest load capacity. For paving purposes both percentages of substitution analyzed are within the parameters that satisfy their respective uses in sub-base layers of flexible pavement.

Surfactants are products widely used in many segments of the industry and because they exhibit many properties they can intensify or improve some properties of the products in which they are used. Natural surfactants are obtained by isolating material of animal or vegetable origin without undergoing chemical changes in its structure. An example of a natural surfactant is that obtained from the Juá husk. Considering the relevance of Juá for obtaining natural surfactants, this work will analyze the effects on physical and mechanical properties that the incorporation, in different proportions, of the powder additive produced from the husk of the trunk of Ziyphus Joazeiro Mart. can offer Portland cement mortar CP-II - Z. The study was carried out at the IFPB - Campus Cajazeiras facilities. Tests were carried out that seek to evaluate the surfactant properties provided by Ziziphus Joazeiro Mart. and its physical and mechanical effects in the mortar. The production of Portland cement mortar combined with the “husk” additive of Ziyphus Joazeiro may be able to result in structures with optimized physical and mechanical characteristics, especially with regard to the consumption of water in the mixture of water, aggregate and binder, in workability and mechanical resistance, consequences resulting from the surfactant properties inherent in the studied composite

The application of psychoanalytic interpretation, the most characteristic feature of which is the accentuation of senses and the assumption of the self-sufficiency of experience, has directed attention to the symbolism of the unconscious, universal meanings and psychological mechanisms inherent in the text. The material for the article was text fragments, photos and comments to them with a total volume of 912 units, which were posted during 2020 on the pages of the social network groups Facebook "Military service - Military Service", "Armed Forces of Ukraine". Results & discussions. Hero-rescuer mythological archetype is at the heart of the Ukrainian non-institutional military discourse. Permanent mythological plot can be traced in the military discourse. Thus, the typical stages of the mythological Hero odyssey were observed: the beginning of the mythological Hero’s adventures is provoked by a catastrophe, which is caused by criminal actions of his enemies; the Hero sets off for a journey to restore the broken harmony; the villains prevent but the Hero passes the trials and wins his reward. His triumph can be represented as the liberation of his country from tyrant. Addressing the mythological plot carries a pragmatic purpose to overcome stress: the military needs unshakable faith in happy end of the problem situation (military conflict in eastern Ukraine) and the idea of mythological Hero helps soldiers to increase self-confidence. Thus, the Ukrainian non-institutional military discourse shows a relationship between the call to the mythological consciousness and coping strategies. Then, there is tendency observed in the military discourse that Hero archetypal image deviates from the archaic archetype framework and the Hero model with an emphasis on the Christian eschatological paradigm dominates. The motif of sacrifice accompanying the Hero image forms the archetypal image of the Hero-holy man. Conclusion. Two Hero models dominate in the Ukrainian non-institutional military discourse. The first model is distinguished by exaggeration. It is a Hero-superman image defined by similarity to mythological heroes, gods, titans. However, this Hero model is not only always accepted by the Ukrainian military but can sometimes arise rejection and protest against Hero-superman image. The second model is a collective image of Ukrainian culture. The People’s Hero model actualizes the features of a toiler who is not a professional soldier, he is a peaceful man. This archetypal image is distinguished by realism and contrast to the Hero-superman image. Key words: Hero archetype, archetypal image, non-institutional military discourse.
A PSYCHOLINGUISTIC STUDY OF THE “THEORY OF MIND” OFTURKISH BILINGUAL CHILDREN
Authors: Kyuchukov Hristo
Published: August 2021

This article presentsthe results of a study with Turkish preschool bilingual children living in Berlin, Germany. This article aims to examine the influence between the level of proficiency in the mother tongue (first language L1) and the official language (second language L2) on the one hand and the “theory of mind” on the other, or more precisely, how the lexical knowledge of L1 and L2 and the understanding of interrogative sentences used with a verb indicating mental states helps to understand the ToM.Research methods and techniques. The study included 18 Turkish-German bilingual children attending a kindergarten in Berlin, Germany. The children were divided into two age groups: 1 g of 4–5 year-olds (8 children) and 2 gr. of 5-6 year-olds (10 children) and were tested in their native Turkish and then in German. The testing was performed in the kindergarten in a separate room, where only the experimenter and the examined child were present. The children are offered the classical tests for “theory of mind”, as well as language tests related to the comprehension of interrogative sentences, containing a verb showing a mental state and comprehension and production of vocabulary in native Turkish and German as a second language for them.The resultsshow that vocabulary is not an important factor, and mastery of interrogative sentences is the factor that helps to understand the “theory of mind”. The results obtained were analyzed statistically by means ofthe t-test.Children with German-Turkish bilingualism understand the vocabulary of their mother tongue well and it is obviously in their passive vocabulary, but this knowledge has not yet passed into their active vocabulary. German vocabulary predominates in the children's active vocabulary. With regard to the level of mastery of interrogative sentences, children are equally good at interrogative sentences in both languages.
Making It Personal? A Comparative Study of Institutional Constraints on Foreign Policy in Russia and China
Authors: Petersson Ivre Joel , Lee Eugene
Published: August 2021

By treating militarism and personalism as institutional constraints on foreign policy, this article examines the role and influence of these constraints on the foreign policies of Russia and China. By looking at empirical evidence the authors argue that domestic institutional constraints in each country have exhibited distinctly different patterns throughout the last twenty years, and this can to some extent explain the difference in their respective foreign policies. However, institutional personalism in China has recently become more similar to that of Russia. The authors argue that current Russian foreign policy bears some elements of similarity suggesting future developments in Chinese foreign policy.
Subgrid-scale Horizontal and Vertical Variations of Cloud Water in Stratocumulus Clouds: A case study based on LES and comparisons with in-situ observations

Published: August 2021

Abstract. Stratocumulus clouds in the marine boundary layer cover a large fraction of ocean surface and play an important role in the radiative energy balance of the Earth system. Simulating these clouds in Earth system models (ESMs) has proven to be extremely challenging, in part because cloud microphysical processes such as the autoconversion of cloud water into precipitation occur at the scales much smaller than typical ESM grid sizes. An accurate autoconversion parameterization needs to account for not only the local microphysical process (e.g., the dependence on cloud water content qc and cloud droplet number concentration Nc), but also the sub-grid scale variability of the cloud properties the determine the process rate. Accounting for subgrid-scale variability is often achieved by the introduction of a so-called enhancement factor E. Previous studies of E for autoconversion focused more on its dependence on cloud regime and ESM grid size, but largely overlooked the vertical dependence of E within the cloud. In this study, we use a large-eddy simulation (LES) model, initialized and constrained with in situ and surface-based measurements from a recent airborne field campaign, to characterize the vertical dependence of the horizontal variation of qc in stratocumulus clouds and the implications for E. Similar to our recent observational study (Zhang et al., 2021), we found that the inverse relative variance of qc, an index of horizontal homogeneity, generally increases from cloud base upward through the lower 2/3 of the cloud, and then decreases in the uppermost 1/3 of the cloud. As a result, E decreases from cloud base upward, and then increases towards the cloud top. We apply a decomposition analysis to the LES cloud water field to understand the relative roles of the mean and variances of qc in determining the vertical dependence of E. Our analysis reveals that the vertical dependence of the horizontal qc variability and enhancement factor E is a combined result of condensation growth throughout the lower portion of the cloud and entrainment mixing at cloud top. The findings from this study indicate that a vertically dependent E should be used in ESM autoconversion parameterizations.
Estimating radiative forcing efficiency of dust aerosol based on direct satellite observations: case studies over the Sahara and Taklimakan Desert
Authors: Tian Lin , Chen Lin , Zhang Peng , Bi Lei
Published: August 2021

Abstract. The direct radiative forcing efficiency of dust aerosol (DRFEdust) is an important indicator to measure the climate effect of dust. The DRFEdust is determined by the microphysical properties of dust, which vary with dust source regions. However,
there are only sparse in situ measurements of them, such as the distribution of the dust aerosol particle size and the complex refractive index in the
main dust source regions. Furthermore, recent studies have shown that the
non-spherical effect of the dust particle is not negligible. The
DRFEdust is often evaluated by estimating given microphysical
properties of the dust aerosols in the radiative transfer model (RTM).
However, considerable uncertainties exist due to the complex and variable
dust properties, including the complex refractive index and the shape of the
dust. The DRFEdust over the Taklimakan Desert and Sahara is derived from the satellite observations in this paper. The advantage of the proposed satellite-based method is that there is no need to consider the
microphysical properties of the dust aerosols in estimating the
DRFEdust. For comparison, the observed DRFEdust is compared with
that simulated by the RTM. The differences in the dust microphysical
properties in these two regions and their impacts on DRFEdust are
analyzed. The DRFEdust derived from the satellite observation is -39.6±10.0 W m-2τ-1 in March 2019 over Tamanrasset in the Sahara
and -48.6±13.7 W m-2τ-1 in April 2019 over Kashi in the Taklimakan Desert. According to the analyses of their
microphysical properties and optical properties, the dust aerosols from the
Taklimakan Desert (Kashi) scatter strongly. The RTM-simulated results (−41.5 to −47.4 W m-2τ-1 over Kashi and −32.2 to
−44.3 W m-2τ-1 over Tamanrasset) are in good agreement with
the results estimated by satellite observations. According to previous
studies, the results in this paper are proven to be reasonable and reliable. The results also show that the microphysical properties of the dust can
significantly influence the DRFEdust. The satellite-derived results can
represent the influence of the dust microphysical properties on the
DRFEdust, which can also validate the direct radiative effect of the
dust aerosol and the DRFEdust derived from the numerical model more directly.
