Negation in Musgum
Authors: Adam Brahim
Published: April 2021

This paper studies the negation construction in musgum language.We collect the musgum data on negation from native users and analyse them in terms of Kayne’s (1994) antisymmetry and Rizzi’s (1997) split CP approaches. We identify the free negation element (á:à) and several negation markers (kài, kirkài, kài tiŋ and kirkài tiŋ) that close independent and complex clauses. In complex structures with completive and relative clauses, the main clause cannot contain a negation marker. In complex structure with adverbial clause, negation marker can be present in main and adverbial clauses. We discover that Negation Phrase is the highest projection, higher than Force Phrase, rejecting the split‐CP projections order of Rizzi (1997). When the negation head is generated, Inflexion Phrase is subject to heavy pied‐piping. It occupies the specifier of Negation Phrase.

Rethinking the Insights from Good Language Learner Studies: Moroccan Learners of EFL as a Case Study
Authors: Nadif Bendaoud , Benattabou Driss
Published: April 2021

Over the recent decades, there has been a growing research interest in placing learners at the heart of any enterprise pertaining to foreign language learning and teaching. Alongside the growth of new perspectives and theories in cognitive psychology and foreign language learning and teaching, research has shifted its focus from the teacher and learning outcomes to the learners and the learning processes. Correspondingly, researchers emphasize the significance of making the learning and teaching paradigms more supportive and responsive to learners’ needs and interests to fully play more active and participatory roles. Drawing on researchers’ contributions in the area of good language learner studies, this paper sets out to examine the relationship between the characteristics of GLLs and language achievement. For this purpose, a sample of (N = 98) senior Moroccan high school students took an EFL achievement test and responded to the GLL questionnaire as designed and developed by Constantinides (2013). Using a Spearman correlational coefficient test and regression analysis, results show that GLLs’ scores significantly correlate (r = .81) and reliably predict the respondents’ achievement test scores. The paper ends with a conclusion and some pedagogical implications to promote EFL learning and teaching.
An Analysis of Engagement Resources in Courtroom Closing Arguments: A Case Study of Jodi Arias Case
Authors: Liang Songman
Published: April 2021

Closing arguments are the last chance for prosecutors and defense lawyers to persuade a judge or jury during the trial, and they play an important role in the court trial, and engagement resources can help enhance the objectivity and persuasiveness of closing arguments. Therefore, this paper adopts engagement system to make a comparative analysis in the closing arguments of the prosecutor and the defense lawyer in Jodi Arias case and to explore the effects of engagement resources in arguments. The study found that dialogic contraction resources help compress the rebuttal space of the opposed views and that dialogic expansion resources help enhance the persuasiveness and objectivity of the arguments. Lawyers on both sides often use dialogic contraction resources, while the defense lawyer uses disclamation resources more frequently and the prosecutor uses proclamation resources more frequently.

Authors: Zainon Hamizatul Hamiza , Yamat Hamidah
Published: April 2021

Blended learning is a combination of traditional teaching method and the use of technology to provide a more organized learning approach in which it gives students extra control over the time, situation and ways of learning. This study investigates the effects of blended learning on motivating secondary level of students to learn English language. A pilot study was conducted. The sample consists of sixty secondary levels of students in a particular school in Shah Alam district, Selangor, Malaysia. The pre and posttest were used to test students’ achievement and the survey adapted from Gardner’s Attitude/Motivation Test Battery was implied to determine students’ motivation level before and after the use of blended learning. The analysis through paired-sample t-test revealed that, there was improvement on the level of motivation of the students and there were significant differences on student’s achievement whereas they performed better after the use of blended learning. The use of blended learning has a positive impact in individual professional development and instead of measuring the effect of blended learning towards student’s achievement; attitude or motivation to learn a language, further studies should also measure the other impact of blended learning itself especially in education.

Authors: Khamkaew Suthee
Published: April 2021

This study aimed to study the effects of integrating online learning in schools during the outbreak of COVID-19 in Thailand from mid-March to July 2020. The participants were 508 students consisting of grade 10-12 levels from five different schools in each province of Thailand. The questionnaire employed via “Poll Feature Line Group” was separated into three categories; 1) The general informations of the students, 2) The advantages of online learning, and 3) The limitations of online learning. 508 students gave the feedback by checking the items of the questionnaires via “Poll Feature Line Group”. The researchers took two weeks to complete the survey in October 2020. The results of the questionnaire were calculated into the statistical values in Percentage, Mean Range and Standard Deviation. The results revealed that the majority of the students studying online studied in grade 12 in science-mathematics program, and Thai and English subjects were primarily available online. The most three advantages were – 1) Online learning promotes the social distancing., 2) Online learning helps students save time and cut on expenses especially transport costs., and 3) Students can communicate via various platforms like Line, Email, Facebook, and Google Classroom. On the contrary, the most limitations were – 1) Students have no chance to participate in extracurricular activities in school., 2) The mere presence of a smartphone reduces students' ability to focus on the lessons., and 3) It can be hard to find answers to questions or resolve difficulties, especially when discussion forum participation is low.

Authors: Rodrigues Ramos Eduardo , Elesbão Heloisa , Borfe Leticia , Mayer Sandra Mara
Published: April 2021

Os atos de violência no ambiente escolar tem se agravado muito nos últimos anos, causando sérios problemas para aqueles envolvidos e muita preocupação aos familiares, comunidade escolar e sociedade em geral. O objetivo deste estudo é fazer uma reflexão a cerca do fenômeno bullying no ambiente escolar através de uma revisão narrativa da literatura sob o ponto de vista teórico e contextual. Utilizou-se como metodologia a busca de materiais relacionados ao tema em bases eletrônicas do SciELO, Portal de Periódicos CAPES, livros e e-books gratuitos publicados nos últimos 10 anos. Para melhor discussão sobre o assunto, foram criados tópicos referentes ao tipo de bullying, forma de envolvimento e ações de enfrentamento ao bullying. São inúmeras as formas de violência que podemos observar no ambiente escolar, sendo que estas possibilitam problemas ainda maiores naqueles que a sofrem. Contudo, situações adversas do convívio familiar saudável tem se associado de diferentes maneiras ao bullying, tornando o agressor passível de promover e reproduzir de forma agressiva essas situações que já ocorrem em seu convívio. As ações que visam enfrentar e inibir os atos de violência no ambiente escolar ainda precisam ser melhor pensados. Estratégias que envolvam a comunidade escolar juntamente com a família e o poder público devem ser elaboradas para que, além da escola, as informações sobre este tema tão importante possa ser discutido e ter maior conscientização da população em geral.
Frères de douleur. Récit d’un ethnologue en pèlerinage à Lourdes
Authors: Amiotte-Suchet Laurent
Published: April 2021

Que connaissent de Lourdes celles et ceux qui ne s’y sont jamais rendus ? Quelques images tout au plus : d’énormes basiliques aux architectures variées qui se chevauchent autour de la grotte des apparitions, des magasins de bondieuseries qui envahissent toute la ville, d’interminables files d’attente de malades en chaise roulante qui prient la Vierge Marie pour qu’elle soulage leur existence… Au début des années 2000, l’auteur a choisi de participer à des pèlerinages à Lourdes pour mieux saisir, de l’intérieur, ce qui pouvait bien motiver ces hommes et ces femmes à effectuer un si long voyage pour réciter des chapelets devant une statue de pierre. Il a revêtu le costume des brancardiers et s’est impliqué dans une association diocésaine franc comtoise. Durant plusieurs années, il a côtoyé les pèlerins, accompagné les personnes malades, partagé la vie d’équipe des brancardiers et des hospitalières, assisté aux offices et aux réunions. Fidèle à la démarche ethnographique, il a consigné dans son journal de terrain tout ce qui lui était donné à voir et à entendre afin de mieux comprendre ce que vivent et partagent les pèlerins de Lourdes.

«ZAKERZONNIA» AS A CONCEPT: THE LINE-THE BORDER-THE TERRITORY-THE LOST REGION?
Authors: ARTYMYSHYN Yuliia
Published: April 2021

The circumstances and context of creating the concept of «Zakerzonnia», which is used for the generalized definition of the whole region of modern Ukrainian-Polish ethnic borderland, are analyzed. The main approaches to explaining the term «Zakerzonnia» and related with it the notion of Curzon Line in encyclopedic articles are defined. In a brief historiographical review emergence and application of the term Curzon Line to the formation of the Polish-Russian and Polish-Soviet border are observed. The settlement's names through which the demarcation line went, its use's political contexts are given. Both the informational and analytical articles in the press of Ukrainian emigration in Europe and proclamation of the leadership of OUN of «Zakerzon Territory» of the late 1940s are considered. These materials highlight the problem of the Polish-Ukrainian border, the forced displacement of Ukrainians. It is noticed, that generally the first description of «Ukrainians living beyond the Curzon Line» was used in these publications. It is confirmed that this interpretation was later transformed into the term «Zakerzonnia» in periodicals of foreign units of OUN of the late 1940s-early 1950s, that is, the territory of the «Western Ukrainian lands», from which the Ukrainians were deported. It is shown that in the Ukrainian centers of the Lemko community of Canada and the USA in the early 1960s, in particular on the pages of periodicals of the Organization of Defense of the Lemkivschyna, the term «Zakerzonnia» is used less frequently than names of historical and ethnographic regions: Lemkivshchyna (Lemko region), Kholmshchyna (Kholm region), Pidliashia, Nadsiannia (Posiannia, Sian region). It is claimed that the active use of the term «Zakerzonnia» occurred in the 1990-2000s due to the activities of social-cultural organizations of deported Ukrainians from Poland.

Keywords: Curzon Line, «Zakerzonnia», concept, Ukrainian-Polish borderland

Currency Substitution and Exchange Rate Volatility in Nigeria: An Autoregressive Distributed Lag Approach
Authors: O. Ajibola Isaiah , U. Udoette Sylvanus , A. Muhammad Rabia , O. Anigwe John
Published: April 2021

This study investigates the relationship between exchange rate volatility and currency substitution in Nigeria, using Autoregressive Distributed Lag (ARDL) model. After accounting for the presence of structural breaks, evidence from the findings shows that domestic interest rate and expected changes in exchange rate are important determinants of currency substitution. In addition, there is empirical support for a positive relationship between exchange rate volatility and currency substitution both in the short- and long-run. This implies that higher real exchange rate volatility is associated with an increased level of currency substitution. In view of these findings, the paper calls for sustained efforts by the monetary authority in containing exchange rate volatility and inflation as a way of curbing the spate of currency substitution in the country.

Published: April 2021

Neste estudo o queijo fundido foi produzido com substituição total e parcial da goma xantana pelo extrato da semente de Moringa e armazenado a 4ºC. Foram estudados a composição química pH, acidez, cor, textura e reologia. A composição química diferiu significativamente (p <0,05) entre as amostras. O teor de proteína foi maior para a amostra contendo apenas extrato de Moringa. A acidez diferiu significativamente (p <0,05) apenas no último dia de armazenamento. Os valores de pH permaneceram dentro dos limites de qualidade estabelecidos (pH ≥ 6,0) para todas as amostras durante os 21 dias de armazenamento. A adição do extrato afetou a cor e a microestrutura das amostras; Queijos processados ​​com extrato adicionado apresentaram partículas de menor tamanho de glóbulos de gordura e distribuídos sem uniformidade. O extrato de Moringa interferiu na textura do produto, revelando-se um grande substituto parcial e / ou total dos conservantes químicos. A amostra com maior substituição de goma pelo extrato de Moringa teve dureza igual à amostra controle. Além disso, esta amostra (T4 - 0,15% goma e 0,35% extrato de Moringa) apresentou maior índice de consistência (K). As amostras não apresentaram diferenças significativas durante o período de armazenamento para coesividade. O perfil reológico mostrou que todas as amostras apresentaram um perfil não newtoniano (pseudoplástico). Dessa forma, acredita-se que a semente da Moringa tenha potencial para uso como substituto de espessante.

Published: April 2021

Radish yield and quality are factors influenced by water stress that may occur during periods of drought or irrigation handled inappropriately, interfering negatively in plants development, producing radishes of inferior quality and in lesser quantity. In addition to irrigation, which makes water available in the system, it is important to maintain it with the use of water-retaining products such as hydrogel. The aim of this work was to evaluate radish yield, submitted to three different hydrogel doses combined with two water slides. The experimental design was in factorial scheme 3 x 2, with three water slides (50%, 75% and 100% Eto – reference evapotranspiration estimate) and two hydrogel doses (40 and 60 g m-2) with four replicates. Number of leaves, horizontal and vertical root diameter (mm), total and shoot length (cm), fresh mass of root and shoot (g), dry mass of shoot and root (g) and yield (t ha-1) were evaluated. The best results, regarding radish production and development, were obtained when using 50% of Eto with 60 g m-2 of hydrogel in combination. Thus, radish cultivation in oxisoil was influenced by the use of hydrogel, which provided a more efficient water level use.

Published: April 2021

O objetivo desta pesquisa foi avaliar a geração de resíduos de pescado e a percepção ambiental dos peixeiros quanto aos impactos ambientais causados pelo armazenamento temporário e a disposição final dos resíduos gerados em três feiras livres do município de Marabá – Pará. O método utilizado foi o indutivo com abrangência quantitativa e qualitativa. Foram efetuadas quatro visitas in loco, para obtenção de dados primários. Os secundários foram obtidos em links eletrônicos de acesso livre. A análise dos dados obtidos indicou que são comercializados nove gêneros de pescados; a maior quantidade comercializada ocorreu na Feira da 28 (2.114,9 kg/mês); foram identificados e quantificados três tipos de residuos orgânicos: um (peles: 77,4±0,0); dois (carcaça, 14,0±4,7) e três (outros 88,4±21,6); o armazenamento temporário é realizado em baldes (8,3±1,5) e sacos plásticos de 100 L (2,3±1,5), foi observada que não há segregação residual (6,7±3,1); todos os indivíduos amostrados (n = 36: 100%) informaram que os resíduos coletados pela prefeitura, são destinados ao aterro controlado sem o tratamento adequado. Em relação a percepção ambiental de impactos causados pelo descarte inadequado, ainda há desconhecimento disso (7,0±2,0); a grande maioria deles não tem conhecimento sobre as alternativas sustentáveis para os resíduos orgânicos (7,3±0,6), mas a minoria conhece (3,7±2,9), e citaram ração animal (5,0±2,7) e adubo orgânico (2,0±3,1) como solução adequada. Logo, as condições higiênico sanitárias nas três feiras não são adequadas e que necessitam urgentemente de correções para adequação às legislações sanitárias e ambientais como, por exemplo, a Resolução CONAMA 275/01.
Desain Koalisi Permanen Partai Politik dalam Sistem Pemerintahan Indonesia
Authors: Siboy Ahmad
Published: April 2021

The pattern of political party coalitions that fluctuate ahead of the general election indicates that the coalitions are not built based on substantial interests but pragmatic interests. As a result, the status of each party becomes unclear, which one acts on the side of the government and which one acts as the opposition. This study aims to discuss the options of permanent coalition patterns that can be applied. The research problem of this study was “What is the permanent coalition design that can be applied in the Indonesian government system?”. This study used normative legal research with statutory, conceptual, and case-study approaches. The results indicated that a permanent coalition is needed to strengthen the coalition pattern of political parties as a support for the Indonesian government system. The permanent coalition design that can be applied is a two-pole model, in which there will only two coalition groups of political parties: parties supporting the government and parties opposing the government. This two-pole model can be balanced in terms of the power between a coalition of government parties and a coalition of opposition parties. Another design that can be adopted is the coalitions which are established based on the similarity of the ideology of each political party.
Environmental predictors of sediment denitrification rates within restored green-lipped mussel Perna canaliculus beds
Authors: Sea MA , Thrush SF , Hillman JR
Published: April 2021

Benthic processes in coastal marine environments can enhance the natural removal of bioreactive nitrogen through denitrification (DNF), a valuable ecosystem service as nutrient over-enrichment intensifies globally. Enhancing ecosystem services is an important justification for restoring coastal ecosystems, and while it is known that epifaunal bivalves (oysters or mussels) are capable of influencing nitrogen cycling, empirical measurement of the role of particular species across a range of environmental conditions is missing. Bivalves within shellfish beds are not uniformly distributed and thus clumps and empty patches within restored beds may differentially impact DNF given the importance of local biogeochemistry. This study reports DNF and respiration rates in 4 restored beds that vary in sediment composition, while identifying which ecological and biogeochemical factors best explain the observed variability in measured fluxes. We deployed benthic chambers in sediments with and without mussels at these sites, and measured net N2 fluxes through membrane inlet mass spectroscopy. Sediment organic matter proved to be the most significant predictor of DNF rates in regression tree and random forest models, suggesting that biodeposition by green-lipped mussels enhances nitrogen removal at these sites and that these effects occur across beds despite differences in mussel density. Greatest DNF rates corresponded to lower sediment chlorophyll a concentrations and higher nitrate/nitrite effluxes measured within chambers. Determining the influence of subtidal mussel restoration on significant sediment processes informs future restoration efforts aiming to maximise this nitrogen removal service, while providing insights on underrepresented oligotrophic systems of the southern hemisphere.
1956: Deleuze and Foucault in the Archives, or, What Happened to theA Priori?
Authors: Gray Chantelle
Published: April 2021

When Gilles Deleuze, in his book on Michel Foucault, asks, ‘who would think of looking for life among the archives?’, he uncovers something particular to Foucault's philosophy, but also to his own: a commitment to the question of what it means to think, and think politically. Although Foucault and Deleuze, who first met in 1952, immediately felt fondness for each other, a growing animosity had settled into the friendship by the end of the 1970s – a rift deepened by theoretical differences. Notwithstanding these difficulties, Foucault and Deleuze shared a love for Nietzsche, as well as a curious fascination with Kant. Kant's influence, which was met with more opposition, is precisely the tension I tease out in this article, showing how Foucault critiques Kant's a priori through his own concept of the historical a priori, along with regularity and resistance, while Deleuze and Guattari, if more obliquely, critique Kant's a priori by further developing Foucault's notion of the historical a priori through their own method of pragmatics, particularly in three chapters of A Thousand Plateaus, namely ‘The Geology of Morals’, ‘Postulates of Linguistics’ and ‘On Several Regimes of Signs’. What I am interested in, then, is Deleuze and Guattari's treatment of redundancy, a concept mentioned seventy times in A Thousand Plateaus. Although not one of their main or most developed concepts, redundancy is a thread that can be traced back to Deleuze's first book, Empiricism and Subjectivity. Moreover, their more developed concepts, for example the diagram, the abstract machine, becoming, micro-politics and the ritornello, as well as their political philosophy, are grounded in their understanding of redundancy, which moves their philosophy beyond mapping out the conditions of possibility (Kant) and demonstrating that the historical a priori emerges as a contingent function of its own expression (Foucault) to the genesis of thought.

During the last couple of decades, the state of the Swedish welfare society has deteriorated. Political decisions concerning the labour market, housing and education have significantly increased precarious conditions for many people. Income inequality and economic difficulties have increased. Changes in the welfare system make it harder to receive adequate support, while the repressive elements have also increased. We argue that critical and radical perspectives in social work can help reverse this negative development. What students learn in their social work education will affect their ways of understanding social problems, their practice, and their ability to work for change. We therefore regard social work education as an important arena for social change. But what is the state of such perspectives at our Swedish universities? This article examines the presence of critical and radical perspectives in the Swedish social work curriculum and attempts to answer the question ”How well equipped are future social workers to work in a critical and radical way?” The study shows that a critical perspective is common in the social work curriculum of some universities, but that critical and radical perspectives in general are absent. We argue that this

The huge biological diversity of the Brazilian Cerrado is an important source of economically interesting microbial agents. The phylum Actinobacteria plays an important role in nutrient cycling, potentially improving their availability to plants. In this study, we isolated an actinobacteria (strain 3AS4) from wheat rhizospheres of crops cultivated in the Cerrado biome. Strain 3AS4 was identified as belonging to the genus Streptomyces and had phosphorus mobilization ability, mineralizing approximately 410 μg ml–1 from phytate, 300 μg ml–1 from calcium phosphate, and 200 μg ml–1 from rock phosphate. The analysis of the actinobacteria crude extract by spectrometric techniques revealed the presence of gluconic and 2-ketogluconic acid, and a greenhouse experiment was carried out to evaluate its plant growth promotion activity in soybean. Soil in its natural condition (with no phosphorus addition), 40 kg ha–1 rock phosphate from Bayovar (RP) added to soil, and triple super phosphate (SPT) added to soil were used. Significant differences in plant height were observed at 6 weeks when the plants were inoculated with the 3AS4 strain. The growth of inoculated plants in natural condition was promoted in 17% compared with the RP and SPT non-inoculated conditions, suggesting that inoculation can enable plants to grow with lower chemical P fertilizers. In the plants that were inoculated with the 3AS4 strain in the RP condition, the plant height increased by approximately 80% and the shoot:root ratio was approximately 30% higher compared to control conditions (non-inoculated plants in natural conditions). 3AS4 has P-solubilizing potential and can be exploited as an inoculant for soybean cultivation. These results suggest that this actinobacterium is a valuable resource for sustainable agriculture and will allow the reduction of phosphate fertilization in the future.

A large proportion of infertility and miscarriage causes are unknown. One potential cause is a defective sperm centriole, a subcellular structure essential for sperm motility and embryonic development. Yet, the extent to which centriolar maladies contribute to male infertility is unknown due to the lack of a convenient way to assess centriole quality. We developed a robust, location-based, ratiometric assay to overcome this roadblock, the Fluorescence-based Ratiometric Assessment of Centrioles (FRAC). We performed a case series study with semen samples from 33 patients, separated using differential gradient centrifugation into higher-grade (pellet) and lower-grade (interface) sperm fractions. Using a reference population of higher-grade sperm from infertile men with morphologically standard sperm, we found that 79% of higher-grade sperm of infertile men with substandard sperm morphology have suboptimal centrioles (P = 0.0005). Moreover, tubulin labeling of the sperm distal centriole correlates negatively with age (P = 0.004, R = −0.66). These findings suggest that FRAC is a sensitive method and that patient age and sperm morphology are associated with centriole quality.
Reactive Oxygen Species-Based Nanomaterials for Cancer Therapy
Authors: Li Yingbo , Yang Jie , Sun Xilin
Published: April 2021

Nanotechnology advances in cancer therapy applications have led to the development of nanomaterials that generate cytotoxic reactive oxygen species (ROS) specifically in tumor cells. ROS act as a double-edged sword, as they can promote tumorigenesis and proliferation but also trigger cell death by enhancing intracellular oxidative stress. Various nanomaterials function by increasing ROS production in tumor cells and thereby disturbing their redox balance, leading to lipid peroxidation, and oxidative damage of DNA and proteins. In this review, we outline these mechanisms, summarize recent progress in ROS-based nanomaterials, including metal-based nanoparticles, organic nanomaterials, and chemotherapy drug-loaded nanoplatforms, and highlight their biomedical applications in cancer therapy as drug delivery systems (DDSs) or in combination with chemodynamic therapy (CDT), photodynamic therapy (PDT), or sonodynamic therapy (SDT). Finally, we discuss the advantages and limitations of current ROS-mediated nanomaterials used in cancer therapy and speculate on the future progress of this nanotechnology for oncological applications.
Data-Driven Computational Social Network Science: Predictive and Inferential Models for Web-Enabled Scientific Discoveries
Authors: Emmert-Streib Frank , Dehmer Matthias
Published: April 2021

The ultimate goal of the social sciences is to find a general social theory encompassing all aspects of social and collective phenomena. The traditional approach to this is very stringent by trying to find causal explanations and models. However, this approach has been recently criticized for preventing progress due to neglecting prediction abilities of models that support more problem-oriented approaches. The latter models would be enabled by the surge of big Web-data currently available. Interestingly, this problem cannot be overcome with methods from computational social science (CSS) alone because this field is dominated by simulation-based approaches and descriptive models. In this article, we address this issue and argue that the combination of big social data with social networks is needed for creating prediction models. We will argue that this alliance has the potential for gradually establishing a causal social theory. In order to emphasize the importance of integrating big social data with social networks, we call this approach data-driven computational social network science (DD-CSNS).
Factors Controlling Natural Gas Accumulation in the Southern Margin of Junggar Basin and Potential Exploration Targets

In this paper, factors controlling natural gas accumulation in the southern margin of Junggar Basin were mainly discussed by a comparison with natural gas generation and accumulation in the Kuqa Depression of Tarim Basin. The southern margin of Junggar Basin and the Kuqa Depression of Tarim Basin are located on the north and south sides of the Tianshan Mountains respectively, and they share the similar sedimentary stratigraphy and tectonic evolution history. In recent several decades, many large gas fields have been found in the Kuqa Depression of Tarim Basin, but no great breakthrough in the southern margin of Junggar Basin. Our results suggest that natural gas in the southern margin of Junggar Basin is mainly thermogenic wet gas, and can be divided into three types as coal-derived gas, mixed gas and oil-associated gas, of which the former two types are dominated. The Jurassic coal measures are the main source rocks of natural gas, and the main gas generation time from this set of source rocks matched well with the formation time of the anticline structures, resulting in favorable conditions for natural gas accumulation. In the western part of the southern margin in the Junggar Basin, the Permian lacustrine and the Upper Triassic lacustrine-swamp source rocks could be important sources of natural gas, and the main gas generation time also matched well with the formation time of traps. Compared with the Kuqa Depression of Tarim Basin, natural gas sources are better in the southern margin of Junggar Basin, and the geologic conditions are favorable for the formation of large oil and gas fields in the southern margin of Junggar Basin. The deep Permian-Jurassic-Cretaceous petroleum system is the most favorable petroleum system for natural gas exploration in the southern margin of Junggar Basin. The western part and the central part of the southern margin in the Junggar Basin could be the first targets for the discovery of the Jurassic coal-derived oil and gas reservoirs. The shallow Cretaceous-Neogene petroleum system is the second target for natural gas exploration.
