EFFICIENCY MEASUREMENT OF CUSTOMER SERVICE CALL CENTER
Authors: Ducic Aleksandra , Savic Gordana , Popovic Milena
Published: January 2021

Customer feedback has become an important policy instrument in the business company, and it is essential for the customer base and policy development. One of the evaluation methods of customer satisfaction and loyalty can be the reports that are created in the company's customer support center. Therefore, companies must maintain a high number of customers to be efficient and successful. Data Envelopment Analysis (DEA) is a linear programming based technique for measuring the relative efficiency of decision-making units (DMUs) where the presence of multiple inputs and outputs makes comparisons difficult. In this paper, the DEA method evaluates the efficiency rate of customer service in 29 call center companies. The study was conducted based on the obtained data for service performed through the telephone. DEA research is based on the data available for the period from September 2017 to April 2019. The main goal of this analysis is to determine which customer-suport call centers in the world are efficient and which are inefficient. Based on the results,, it was established that a small number of centers are efficient in the observed period. Furthermore, for inefficient centers, comparing those to efficient ones, the DEA method is giving us information why they are inefficient and could direct the future development policy.
UNTANGLING THE CORPORATE SOCIAL RESPONSIBILITY-FINANCIAL PERFORMANCE PARADOX: THE ROLE OF COMPETITIVE ACTIVITY
Authors: Lee Hun , Andrevski Goce , Ferrier Walter
Published: January 2021

A central debate in corporate social responsibility (CSR) research is whether CSR hurt or help shareholders. Our study suggests that this paradoxical tension between social and competitive activities of firms is a manageable resource-allocation decision. By disaggregating competitive activity into its different forms – intensity and complexity – we develop a model that explains how firms can alleviate the resource allocation tension to improve performance. High CSR firms can enhance short-term performance by reconfiguring its resource base and reducing competitive intensity – the frequency of competitive actions. Alternatively, they can increase long-term performance by transforming its resource base and increasing competitive complexity – the variety and novelty of competitive actions. Overall, our empirical findings suggest that the positive effect of CSR on firm performance is conditional on firms’ ability to adjust the intensity and complexity of their competitive activity. Our results are robust across competitive environments with different levels of competitive pressure.

Published: January 2021

In our research, we aim to extend the debate about the new role of universities as an entrepreneurial ecosystem, by examining some underlying and fundamental, but very important dimensions for further and deeper examinations of this subject such as university ownership, field of study and the entrepreneurial education concentration within, as well as the university environment and learning programs. The research considers an analysis based on major implications proposed by the GUESSS Project (Global University Entrepreneurial Spirit Students' Survey) to generate in-depth insights into students’ entrepreneurial intentions. A hierarchical multiple regression was run to determine the effect of different variables related to university ecosystem on entrepreneurial intention of student population. The data comes from the GUESSS survey 2018, conducted at state and private universities in North Macedonia, with undergraduate and postgraduate students. A sample of 398 respondents was collected. The study contributes to the existing literature on nascent entrepreneurship and start-up behaviour in understanding the impact of key elements of an entrepreneurial ecosystem within a university on student start-up activity.

ZERO KNOWLEDGE PASSWORD AUTHENTICATION PROTOCOL
Authors: DATTA NIVEDITA
Published: January 2021

In many applications, the password is sent as cleartext to the server to be authenticated thus providing the eavesdropper with opportunity to steal valuable data. This paper presents a simple protocol based on zero knowledge proof by which the user can prove to the authentication server that he has the password without having to send the password to the server as either cleartext or in encrypted format. Thus the user can authenticate himself without having to actually reveal the password to the server. Also, another version of this protocol has been proposed which makes use of public key cryptography thus adding one more level of security to the protocol and enabling mutual authentication between the client & server.
COMMUNICATING WITH AN ENERGY METER USING IEC 62056 THROUGH TCP/IP PROTOCOL
Authors: R RAJISHA , JAGANNIVAS JIJI , U SHAILESHWARI M
Published: January 2021

Device Language Message Specification (DLMS) is an application layer protocol designed to support messaging to and from energy distribution devices in a computer integrated environment. COSEM, the Companion Specification for Energy Metering, addresses the meter as an integrated part of a commercial process, which starts with the measurement of the delivered product (energy) and ends with the revenue collection. The DLMS/COSEM specification specifies a data model and communication protocols for data exchange with metering equipment. Communication with electricity metering equipment using the COSEM interface classes is based on the client – server paradigm, where the Meter plays the role of server and the client is a Meter Reading Instrument. Different types of communication media are used to retrieve parameters from energy meter. This paper aims to establish a communication with energy meter by using DLMS/COSEM and access meter data with TCP/IP based communication media.

Authors: DIGAL JEMIMAH , SMYS S.
Published: January 2021

The last mile access for residential user are asymmetric. As a result an equal split between the uplink and downlink channel cause inefficient bandwidth utilization. Improper allocation will severely affect the traffic. In this work the main focus is TCP performance during improper bandwidth allocation. The TDD framing in Wi-max is adaptive in the order to make the downlink to uplink bandwidth ratio vary with time. Adaptive channel split ratio, adjust the bandwidth ratio with the help of present traffic profile, transport layer parameters and wireless interference. This scheme will provide higher throughput. The performance of the proposed scheme is validated via ns-2 simulation.
MINIMIZATION OF MOBILE AD HOC NETWORKS ROUTING ATTACKS USING DS MATHEMATICAL THEORY
Authors: JASMINE SK. , SUBBARAO CH. , BABU P.
Published: January 2021

Mobile Ad hoc Networks (MANET) have been highly vulnerable to attacks due to the dynamic nature of its network infrastructure. Among these attacks, routing attacks have received considerable attention since it could cause the most devastating damage to MANET. Even though there exist several intrusion response techniques to mitigate such critical attacks, existing solutions typically attempt to isolate malicious nodes based on binary or naı¨ve fuzzy response decisions. However, binary responses may result in the unexpected network partition, causing additional damages to the network infrastructure, and naı¨ve fuzzy responses could lead to uncertainty in countering routing attacks in MANET. In this paper, we propose a risk-aware response mechanism to systematically cope with the identified routing attacks. Our risk-aware approach is based on an extended Dempster-Shafer mathematical theory of evidence introducing a notion of importance factors. In addition, our experiments demonstrate the effectiveness of our approach with the consideration of several performance metrics

Published: January 2021

Research of the past years has led to numerous novel developments and approaches for wireless sensor networks (WSNs). However, most previous work has focused on either mathematical analysis or theoretical algorithms with extensive simulation results. In this paper, in order to realistically understand the complexity of WSNs, a ZigBee/IEEE 802.15.4 platform has been designed and implemented. Based on an IEEE 802.15.4 radio and ZigBee protocol stack, the developed ITRI ZBnode is an autonomous wireless communication and computing platform aimed at fast prototyping and research in WSNs. The platform attempts to provide a low data rate, low power, and low cost wireless networking on the device-level communication. Finally, examples of tree and mesh network formation are provided to demonstrate practicability of the developed ZBnode platform.
A VLSI DSP DESIGN AND IMPLEMENTATION OF COMB FILTER USING UN-FOLDING METHODOLOGY
Authors: GUPTA PURU , RAWAT TARUN KUMAR
Published: January 2021

In signal processing, a comb filter adds a delayed version of a signal to itself, causing constructive and destructive interference. Comb filters are used in a variety of signal processing applications that is Cascaded Integrator-Comb filters, Audio effects, including echo, flanging, and digital waveguide synthesis and various other applications. Comb filter when implemented has lower through-put as the sample period can not be achieved equal to the iteration bound because node computation time of comb filter is larger than the iteration bound. Hence throughput remains less. This paper present the comb filter using one of the methodology needed to design custom or semi custom VLSI circuits named as Un-Folding which increases the throughput of the comb filter. Un-Folding is a transformation technique that can be applied to a DSP program to create a new program describing more than one iteration of the original program. It can unravel hidden con-currency in digital signal processing systems described by DFGs. Therefore, unfolding has been used for the sample period reduction of the comb filter for its higher throughput.

Authors: Souza Sandra , Oliveira Maria Auxiliadora
Published: January 2021

O presente estudo versa sobre a atuação dos professores da Educação Profissional de ensino médio com pessoas com deficiência e se constituiu, a partir da necessidade de se pesquisar, com maior profundidade, se esses docentes têm trabalhado, no seu dia a dia, nas salas de aulas, na perspectiva da Educação Inclusiva. Tendo em vista que a possibilidade de avanço na escolaridade tornou-se possível às pessoas com deficiência, essa modalidade educacional se apresenta como uma grande oportunidade de inserção desses sujeitos, tanto no mundo laboral quanto no societário. A pesquisa se configurou como uma pesquisa qualitativa, lançando-se mão de uma revisão bibliográfica dos trabalhos de, principalmente, Carvalho (1997), Duek (2014), Manica e Caliman (2015), Mazzotta (2005), Silva (2015) e Souza (2008), além de documentos nacionais e internacionais. Realizou-se, também, uma inserção no campo, na qual foram realizadas entrevistas semiestruturadas com docentes, estudantes e coordenadores de cursos técnicos de nível médio, de duas instituições da Rede Federal de Educação Profissional Científica e Tecnológica (RFEPCT), em Minas Gerais e duas Escolas de Educação Profissional, de nível médio, em Portugal. Nas instituições pesquisadas, tanto no Brasil quanto em Portugal, constatou-se um posicionamento que representa muitos professores no que tange ao processo inclusivo de estudantes com Necessidades Educacionais Especiais, em geral, e com deficiência, em particular. Dessa forma, foi possível, através dela, verificar como os professores têm lidado com o processo inclusivo nas salas de aulas, e que ações ainda precisam ser implementadas para que a Educação Inclusiva se concretize, efetivamente.
Inserção da mulher no mercado de trabalho brasileiro: violência simbólica e consolidação da dominação masculina nas relações de trabalho
Authors: Maia Eloiza , Quirino Raquel
Published: January 2021

Este artigo tem por objetivo trazer um breve histórico sobre a precária inserção da mulher no mercado de trabalho brasileiro, identificar as possíveis causas que motivam essa precarização e divulgar alguns dados do Instituto Brasileiro de Geografia e Estatísticas-IBGE, sobre estatísticas de gênero. A pesquisa é exploratória, tendo como instrumentos a pesquisa bibliográfica e análise de dados. O trabalho divide-se em três momentos. O primeiro traça um breve perfil que revela as condições subalternas em que as mulheres começam a entrar nesse universo assalariado. Na grande maioria das vezes, em funções menos qualificadas e com salários abaixo dos valores que se pagam aos homens, inclusive em situações quando exercem as mesmas funções, como no caso de empregados domésticos. No segundo momento, busca-se uma teoria de base fundada em Bourdieu, que evidencia a violência simbólica e a dominação masculina, inserida na sociedade pelo patriarcado, pelo racismo e pelo capitalismo, condição essa aceita por todos como uma “coisa normal”. No terceiro e último momento, são trazidos alguns dados do IBGE, publicados no boletim sobre Estatísticas de Gênero Indicadores Sociais das Mulheres no Brasil, com última atualização em junho de 2018, baseados na Pesquisa Nacional por Amostra de Domicílios contínua - PNAD. Com os resultados, fica evidente que, ainda há muita luta pela frente, para conscientizar a sociedade sobre mudanças nesse embate, que traz embutido, relações de poder entre os sexos, distribuídas de forma desigual, cabendo sempre à mulher uma posição inferior na organização social
Estratégias para acelerar a circulação econômica das mercadorias e seus efeitos patológicos sobre a saúde da classe trabalhadora
Authors: Andrade Vanessa , Antunes Ricardo
Published: January 2021

Este trabalho é parte de minha pesquisa de doutorado que está em andamento. Ela visa tentar compreender com maior profundidade a circulação econômica da mercadoria, por meio de duas estratégias econômicas contemporâneas utilizadas pelo capital para sua dinamização, principalmente na facilitação das trocas: o sistema de crédito e o papel da Neuroeconomia. Em específico, para a discussão aqui, trago apenas parte deste meu trabalho, a que corresponde à questão do papel do envolvimento do trabalhador e sua transformação em consumidor, que se deu pelo apelo a suas emoções, por intermédio: dos meios de comunicação e da publicidade, que foram usados para estimular a circulação econômica da mercadoria, mediante as encantadoras campanhas de venda ao longo do século XX e inicio do século XXI. Com alguns números alarmantes, referente a saúde do trabalhador, adentraremos na discussão das consequências ocasionadas pela forma de produzir e reproduzir do capital, que submete os indivíduos a persuasão de forma imperceptível, movimento este, primeiramente realizado pelos mecanismos da propaganda e pautados nos estudos da Psicologia, e atualmente articulam as novidades da Neurociência para aprimorar o ciclo de consumo. Principalmente, trago de maneira resumida, uma discussão dialética das relações sociais e de produção e reprodução capitalista, que produzem transtornos mentais e fisiológicos na classe trabalhadora. Em especifico discutirei sobre o Transtorno Compulsivo de Compras (TCC) e suas comorbidades.

Published: January 2021

O presente artigo é resultado das discussões realizadas no âmbito do grupo de pesquisa tecnologias digitais no contexto educacional amazônico. E que, diante da pandemia do Coronavírus, houve a necessidade de investigar como alunos e professores estavam mediando o ensino remoto em uma instituição educacional. As reflexões baseiam-se nos entendimentos teóricos e práticos dos autores: Kenski (2010), Mill e Pimentel (2013) e Belloni (2010). As análises apresentadas advêm dos dados coletados com professores coordenadores, alunos e pais, que utilizaram as tecnologias digitais, disponibilizadas pela escola no período da quarentena. Os resultados apontam que apesar do reconhecimento de que as tecnologias digitais contribuem com as práticas pedagógicas em EaD, no entanto, fatores relacionados a ausência de infraestrutura adequada bem como formação pedagógica e instrumentos tecnológicos insuficientes, caracterizam-se como obstáculos à articulação das tecnologias com as práticas que favoreçam o processo ensino aprendizagem na escola em questão.

In the Service of God and Humanity
Authors: Adeleke Tunde
Published: January 2021

An analysis of Black activist Martin R. Delany's humanist vision for a world where
everyone feels validated and empowered Martin R. Delany (1812–1885) was one of the
leading and most influential Black activists and nationalists in American history. His
ideas have inspired generations of activists and movements, including Booker T.
Washington in the late nineteenth century, Marcus Garvey in the early 1920s, Malcolm X
and Black Power in 1960s, and even today's Black Lives Matter. Extant scholarship on
Delany has focused largely on his Black nationalist and Pan-Africanist ideas. Tunde
Adeleke argues that there is so much more about Delany to appreciate. In the Service of
God and Humanity reveals and analyzes Delany's contributions to debates and discourses
about strategies for elevating Black people and improving race relations in the
nineteenth century. Adeleke examines Delany's view of Blacks as Americans who deserved
the same rights and privileges accorded Whites. While he spent the greater part of his
life pursuing racial equality, his vision for America was much broader. Adeleke argues
that Delany was a quintessential humanist who envisioned a social order in which
everyone, regardless of race, felt validated and empowered. Through close readings of
the discourse of Delany's humanist visions and aspirations, Adeleke illuminates many
crucial but undervalued aspects of his thought. He discusses the strategies Delany
espoused in his quest to universalize America's most cherished of values—life, liberty,
and the pursuit of happiness—and highlights his ideological contributions to the
internal struggles to reform America. The breadth and versatility of Delany's thought
become more evident when analyzed within the context of his American-centered
aspirations. In the Service of God and Humanity reveals a complex man whose ideas
straddled many complicated social, political, and cultural spaces, and whose voice
continues to speak to America today.

Published: January 2021

Neste artigo apresentamos levantamento da historiografia produzida nas últimas quatro décadas sobre o mundo do trabalho no Mato Grosso do Sul, destacando a diversidade de temas, sujeitos e fontes, que tem contribuído para ampliar e aprofundar a interpretação da região como constituinte do todo nacional em interfaces com a transnacionalidade, em vista de suas características fronteiriças que demarcam especificidades na formação da classe trabalhadora. Partimos de um debate sobre as noções – nem sempre explícitas e nem sempre publicamente admitidas – de centro e de periferia nas historiografias nacionais que contagiam, também, a historiografia social do trabalho. Para tanto, inicialmente, faz-se breve incursão sobre as fontes e a historiografia do movimento operário em países da Bacia Platina (Argentina, Uruguai e Paraguai), com foco na compreensão de dicotomias sintetizantes de regiões interioranas, presentes em parte do movimento operário e da historiografia desses países, tais como: ocidente/oriente, civilização/barbárie, centro/periferia, litoral/sertão.
Preliminary Test of the Potential of Contact With Dogs to Elicit Spontaneous Imitation in Children and Adults With Severe Autism Spectrum Disorder
Authors: Silva Karine , Lima Mariely , Fafiães Carla , Sinval Jorge , de Sousa Liliana
Published: January 2021

Importance: Finding strategies to enhance imitation skills in people with autism spectrum disorder (ASD) is of major clinical relevance.

Objective: To evaluate whether contact with dogs may be a useful approach to elicit spontaneous imitation in people with ASD.

Design: Participants completed a spontaneous imitation task under three experimental conditions: after a free-play interaction with a live dog, after a free-play interaction with a robotic dog, and after a waiting period that involved no stimuli.

Participants: Ten children and 15 adults diagnosed with severe ASD.

Outcomes and Measures: Imitation ratio, imitation accuracy, and indicators of social motivation.

Results: Children appeared more motivated and engaged more frequently in spontaneous imitation in the live dog condition than in the other conditions. No differences between conditions were found for adults for imitation or social motivation. However, correlations suggested a possible trend for adults in time spent engaging with the live dog before testing and in increased imitation frequency.

Conclusions and Relevance: The results are preliminary and do not indicate the utility of integrating (live) dogs into interventions aimed at promoting social motivation and enhancing imitation skills in people with ASD. However, they suggest that doing so holds promise. Larger scale studies are now needed.

What This Article Adds: This research calls for occupational therapy practitioners’ attention to the potential benefits that may derive from using dogs to promote spontaneous imitation, and increase imitation performance, in people with ASD, particularly children.
Circulating exosomal lncRNAs in patients with chronic coronary syndromes
Authors: Zheng Meili , Han Ruijuan , Yuan Wen , Chi Hongjie , Zhang Yeping , Sun Kai , Zhong Jiuchang , Liu Xiaoyan , Yang Xinchun
Published: January 2021

Introduction

The concept of chronic coronary syndrome (CCS) was first presented at the European Society of Cardiology Meeting in 2019. However, the roles of exosomal lncRNAs in CCS remain largely unclear.

Material and methods

A case-control study was performed with a total of
218 participants (137 males and 81 females), including 15 CCS patients and
15 controls for sequencing profiles, 20 CCS patients and 20 controls for the first validation, and 100 CCS patients and 48 controls for the second validation. Exosomes were isolated from the plasma of CCS patients and controls, and exosomal lncRNAs were identified by sequencing profiles and verified twice by qRT-PCR analysis. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic value of exosomal lncRNAs for CCS patients.

Results

A total of 152 significantly differentially expressed lncRNAs with over two-fold changes were detected in plasma exosomes of CCS patients, including 90 upregulated and 62 downregulated lncRNAs. Importantly, 6 upregulated lncRNAs with the top fold changes were selected for validations. Exosomal lncRNAs ENST00000424615.2 and ENST00000560769.1 were significantly elevated in CCS patients in both validations compared with controls. The areas under the ROC of lncRNAs ENST00000424615.2 and ENST00000560769.1 were 0.654 and 0.722, respectively. Additionally, exosomal lncRNA ENST00000560769.1 was significantly higher in the CCS patients with more diseased vessels (p = 0.028).

Conclusions

Exosomal lncRNA ENST00000424615.2 and ENST00000560769.1 were identified as novel diagnosis biomarkers for patients with CCS. Moreover, exosomal lncRNA ENST00000560769.1 was significantly higher in the CCS patients with more diseased vessels, and might be associated with a poor prognosis.

Introduction

Limited studies have suggested that calprotectin may take part in the pathophysiology of community-acquired pneumonia (CAP). Nevertheless, there is no clinical study analysing the role of S100A8 in CAP patients. The objective of this study was to analyse the association of serum S100A8 with the severity of CAP and determine the cut-off values of S100A8 for predictive power based on a cross-sectional study.

Material and methods

A total of 200 CAP patients and 100 normal subjects were recruited. Demographic data, clinical information, and serum were collected on admission. S100A8 and inflammatory cytokines were detected using ELISA and RT-PCR. All statistical analyses were performed with SPSS 19.0.

Results

Serum S100A8 was increased in CAP patients on admission. Serum S100A8 was gradually increased in parallel with CAP severity scores. Serum S100A8 was positively correlated with CAP severity scores, blood routine parameters, and inflammatory cytokines. Furthermore, univariate and multivariate logistical regression revealed that there were positive associations between serum S100A8 with CRB-65, PSI, and CURXO. Moreover, the predictive capacity of serum S100A8 was determined by ROC curve analysis. The area under the curves of S100A8 for CAP and CAP severity were 0.855 and 0.893, respectively. Mechanistic analysis found that S100A8 knockdown alleviated streptococcus pneumoniae-evoked inflammatory cytokines in A549 cells.

Conclusions

Serum S100A8 on admission was positively associated with the severity of CAP. S100A8 knockdown alleviates streptococcus pneumoniae-evoked inflammatory cytokines in A549 cells, indicating that S100A8 may exert a significant effect on the pathophysiology of CAP and could be an early serum diagnostic biomarker for CAP.

After the Relational Turn: The Problem of Social Identity
Authors: Szlachcicowa Irena
Published: January 2021

Relational sociology rejects substantialism and focuses its attention on the complexity and dynamics of all forms of social life and the subjective nature of action. Relational thinking is an alternative attitude to both functional structuralism and strongly individualistic-oriented theories. Relationality emphasizes the processual and emergent nature of reality. Actions— individual and collective—appear as successive stages of a specific process of events, and result from the configuration of relations and social interactions constituting a particular situation. Different conceptions of identity have been developed within relationally oriented sociology. The aim of the article is to summarize the narrative and realistic approaches, and to present how much they differ in their ontological assumptions. The constructionist concept of narrative identity presented by Margaret R. Somers, and Kenneth J. Gergen’s project of a “relational self,” illustrate the narrative approach. Pierpaolo Donati’s concept of the relational subject and the theory of agency developed by Margaret S. Archer exemplify the position of critical realism.
The Impact of Managerial Ability on the Relation between Real Earnings Management and Future Firm’s Performance: Applied Study
Authors: Hessian Mohamed
Published: January 2021

This study aims to investigate the managerial ability of executives’ managers’ role on mitigating the negative impact of real earnings management on future firm’s performance. The researcher operationalizes managerial ability by using a measure developed by Demerjian, Lev, and McVay (2012). This measure captures managers’ ability to efficiently convert firm resources into sales revenue relative to their industry peers. In other words, higher-ability managers are more likely to generate more sales revenue for a given set of resources compared to lower-ability managers. The researcher follows Roychowdhury (2006) and Kothari et al. (2016) to calculate abnormal sales, abnormal production costs, and abnormal discretionary expenses. To capture the total effects of three REM methods an aggregate REM that is a proxy for real earnings activities was used. Following Gunny (2010) and Huang & Sun (2017) future performance proxies are ROA and operating cash flows to total assets (CFO) for the next three years each year. Using a panel sample of 605 firm-year observations from 2005 to 2015. The study concluded that there is a positive significant relationship between the managerial ability of managers and earnings management through manipulating of real operational activities.

Abstract. As an important atmosphere constituent, sulfate aerosols exert profound impacts on climate, ecological environment, and human health. The Tibetan Plateau (TP), identified as the Third Pole, contains the largest land ice masses outside the poles and has attracted wide attention on its environment and climatic change. However, the mechanisms of sulfate formation in this specific region remain poorly characterized. Oxygen-17 anomaly (Δ17O) has been used as a probe to constrain the relative importance of different pathways leading to sulfate formation. Here, we report the Δ17O values in atmospheric sulfate collected at a remote site in the Mt. Everest region to decipher the possible formation mechanisms of sulfate in such a pristine environment. Throughout the sampling campaign (April–September 2018), the Δ17O in non-dust sulfate show an average of 1.7 ± 0.5 ‰ which is higher than most existing data in modern atmospheric sulfate. The seasonality of Δ17O in non-dust sulfate exhibits high values in the pre-monsoon and low values in the monsoon, opposite to the seasonality in Δ17O for both sulfate and nitrate (i.e., minima in warm season and maxima in cold season) observed from diverse geographic sites. This high Δ17O in non-dust sulfate found in this region clearly indicates the important role of the S(IV) + O3 pathway in atmospheric sulfate formation promoted by high cloud water pH condition. Overall, our study provides an observational constraint on atmospheric acidity in altering sulfate formation pathways particularly in dust-rich environments, and such identification of key processes provides an important basis for a better understanding of the sulfur cycle in the TP.
