Un anti-héros des deux mondes ? Ronald MacIver et l’histoire atlantique du volontariat armé (1860-1880)
Authors: Collectif 1
Published: October 2019

Cet article se propose d’étudier la trajectoire d’un volontaire armé du xix e  siècle, Ronald MacIver (1841-1907), à partir des biographies qui lui ont été consacrées à la fin du xix e  siècle. Hors du commun, son parcours compte une quinzaine d’engagements différents dans les années 1860 et 1870, principalement en Europe et en Amérique. Le propos de l’article n’est pourtant pas de retracer ce parcours, ni même d’en analyser les étapes. La pérégrination transatlantique de MacIver est prise comme point d’observation des mutations qui marquent à cette époque le monde atlantique. L’un des objectifs de l’article est d’ailleurs de défendre la pertinence d’une telle échelle d’analyse par la mise en évidence de la connexion entre théâtres européens et américains à travers ces circulations transnationales. La réflexion s’attache d’abord à examiner les dimensions personnelles du parcours de MacIver : s’il correspond à une carrière militaire qui s’élabore par-delà les frontières, il est aussi motivé par des considérations politiques conservatrices. L’accent est ensuite mis sur les dimensions concrètes et pratiques de la trajectoire de MacIver : par l’examen des conditions de possibilité du volontariat dans la seconde moitié du xix e  siècle, l’article se propose de mettre en lumière l’insertion du volontariat militaire dans des logiques complexes et contradictoires à l’échelle du monde atlantique. Le dernier moment de la réflexion réconcilie en quelque sorte échelle individuelle et échelle globale en se centrant sur les réseaux de combattants et sur leur rôle dans l’émergence, y compris du point de vue des acteurs du temps, d’un monde atlantique espace d’engagement militaire et d’action politique.
Le dialogue au travail comme source de bien commun. Une étude exploratoire auprès d’une structure associative à vocation sociale et éducative
Authors: Moneyron Jean-Didier
Published: October 2019

La recherche dans le domaine de l’éthique questionne aujourd’hui les organisations sur leur implication dans le bien commun. Cette étude qualitative a été menée dans une association nationale à vocation éducative et sociale. 89 entretiens semi-directifs ont été réalisés ainsi que 8 focus groups et 25 observations non participantes. Elle montre que le travail peut être géré comme un commun au bénéfice de ses bénéficiaires : salariés, managers, institutions et usagers. Cette gestion se met en place grâce aux espaces de dialogue lorsque les attentes des salariés concernant la sécurisation de leur activité sont satisfaites par l’activité de l’encadrement, selon une dynamique de don/contre-don. A ces conditions, le dialogue au travail devient source de bien commun, et l’attention portée à ce dernier renforce la coopération.
Les contributions des pratiques managériales participatives à l’engagement organisationnel affectif des salariés. Une analyse tétraclasse
Authors: Valéau Patrick , Llosa Sylvie
Published: October 2019

Les pratiques managériales participatives étaient initialement envisagées comme des « facteurs plus » favorisant l’engagement organisationnel affectif. Notre étude montre que certaines de ces pratiques sont devenues, avec le temps, des « facteurs clés » avec des effets sur l’engagement, mais aussi, lorsqu’elles sont insuffisamment développées, des effets sur le désengagement. Nous avons exploré cette proposition initiale sur sept pratiques en appliquant l’analyse tétraclasse aux données recueillies auprès de 230 salariés d’un groupe agroalimentaire. Nos résultats soulignent que la gestion des carrières et la reconnaissance sont des pratiques clés dont le développement contribue à l’engagement et dont les absences se traduisent par du désengagement. Dans l’organisation étudiée, la participation et l’information descendante, mais aussi la formation et l’autonomie, restent des pratiques comparativement moins impactantes. De façon inattendue, l’équité salariale apparaît comme une pratique contribuant uniquement à l’engagement, mais dont les manques n’ont que peu d’effets sur le désengagement. Ces résultats contribuent à la réflexion théorique sur le management participatif, tout en fournissant un outil de hiérarchisation aisément accessible aux praticiens.
Le paysage paradisiaque du jardin d’Éden (Gn 2-3)
Authors: Titus Joseph
Published: October 2019

La nature est l’un des moyens par lesquels Dieu s’est révélé à l’humanité. Dans la Bible, Dieu se manifeste d’abord à travers le jardin d’Éden décrit en Gn 2-3. Cet article porte sur le paysage du jardin d’Éden en Gn 2 et tente de comprendre comment le second récit de la création élabore le paysage paradisiaque de ce jardin, premier lieu de rencontre avec Dieu, et comment ce don de Dieu va être abîmé par le péché de l’homme en Gn 3. Ce récit n’évoque pas qu’une situation perdue, mais un projet de vie pour les humains. Il met également en évidence la manière dont le paysage d’Éden nous conduit à une meilleure compréhension de Dieu qui nourrit nos âmes de sa présence aimante et associe les êtres humains à sa création.
Jardin, ville, Venise
Authors: Carraud Christophe
Published: October 2019

La Bible nous mène du jardin à une ville. De part et d’autre du temps, ces images règlent la réalité où nous sommes. Elles la règlent et elles la hantent. Comment faire, s’agissant des lieux que nous habitons, pour ne pas voir dans ces grandes références bibliques de simples métaphores ? C’est à cette question que l’on entend répondre, afin de montrer que ce dispositif imaginaire est nécessaire à une pensée de la ville et du paysage. Oublier l’un des deux termes, c’est condamner le travail du présent à l’aporie, et répondre à ce que l’on croit des mythes pour favoriser soit l’utopie constructiviste de la ville, soit l’utopie régressive du jardin. Or, l’invisible ou l’image est un principe de discernement. La part d’invisibilité de la ville, c’est le jardin ; la part d’invisibilité du jardin, c’est la ville. Telle est la négociation humaine entre les deux termes en tension – au point qu’on peut appeler paradis, par métaphore en effet, le degré le plus humain de la négociation : ce qui reçoit sa mesure de l’accomplissement ici même de ces deux dimensions. C’est en fonction de cela que se juge notre manière d’habiter. Venise est un exemple de cette négociation. Elle montre, dans la réussite de sa négociation propre, qu’ailleurs ce n’est pas le Paradis qu’on a perdu, ni la ville vers laquelle tendre (et s’il s’agit de mythes, la question, précisément, ne se pose pas dans l’histoire), mais le milieu, l’ ici même dans la tension qui le constitue.
Nietzsche : méditation alpestre et volonté de puissance
Authors: Métayer Guillaume
Published: October 2019

L’article décrit le poème «  An die Melancholie  » (1871) de Friedrich Nietzsche comme un moment charnière et essentiel de l’évolution de la philosophie de Nietzsche, celui d’une première intuition de la notion de « volonté de puissance » («  Wille zur Macht  »). Le philosophe y détourne la longue tradition allemande des hymnes à la mélancolie, en même temps qu’il subvertit les poèmes philosophiques – darwiniens notamment – de son temps, pour dépasser son pessimisme schopenhauerien. Plus qu’un décor, le paysage alpestre de Gimmelwald (Suisse) joue un rôle crucial dans ce dépassement comme cadre d’une explication avec la Mélancolie allégorique de Dürer.
Alfred Baudrillart répond à l’appel de Dieu : le récit d’une conscience libérée
Authors: Bordeyne Philippe
Published: October 2019

Un récent dépôt aux archives de l’Institut catholique de Paris permet de publier une lettre inédite dans laquelle Alfred Baudrillart annonce à Mgr Maurice d’Hulst, le 18 septembre 1887, sa décision de devenir prêtre. En introduction à cette lettre, l’article resitue, en s’appuyant sur d’autres documents inédits, les liens intellectuels et spirituels unissant le premier recteur de l’Institut au jeune historien qui allait en devenir le troisième en 1907, et ce jusqu’en 1942. La lettre de Baudrillart nous fait pénétrer dans le contexte religieux de l’époque à partir du débat intérieur de sa conscience : crainte de pécher gravement contre Dieu en négligeant son appel, difficulté pour un brillant normalien de renoncer à la tradition familiale du service de l’université publique en devenant clerc, force émouvante d’une réponse de liberté forgée dans un colloque intime avec Dieu.
Joseph Rambaud, professeur d’économie à la faculté catholique de droit de Lyon, et la question sociale
Authors: Biscay Myriam
Published: October 2019

Le xix e siècle marque l’émergence de l’enseignement de l’économie politique au sein de différentes structures et, à la fin du siècle, les facultés catholiques de droit nouvellement créées ne négligent pas cette discipline. Ainsi, Joseph Rambaud, notable lyonnais, dispense à la Faculté catholique de droit de Lyon de 1885 à 1919 le cours d’économie politique ; ses différents manuels et articles témoignent de son intérêt pour la matière. Le xix e siècle se caractérise également par ce que l’on nomme « la question sociale », et, à ce titre, différentes positions sont prises par les spécialistes d’économie pour répondre à ce contexte de revendications ouvrières. Les catholiques se montrent globalement soucieux de cette « question sociale », il suffit de songer au mouvement du catholicisme social qui apparaît à cette époque ; toutefois ils se divisent cependant en deux écoles opposées par la conception qu’elles se font du rôle de l’État dans la résolution des problèmes sociaux. La pensée de Joseph Rambaud sur la question sociale est ainsi analysée à l’aune de ce contexte.
Jérémie 36 : la revendication d’un texte d’autorité ?
Authors: Van Hoi Nguyen
Published: October 2019

Le chapitre 36 du livre de Jérémie a été souvent étudié pour expliquer la chute de Jérusalem à cause du rejet de la Parole par le roi Yoyaqim, décrit comme antitype de son père Josias en 2 R 22-23. Mais à y regarder de près, Jr 36 accorde une grande importance à l’écriture et à la figure de Jérémie qui est décrit avec des traits mosaïques. Il s’avère qu’en valorisant l’autorité de Jérémie l’auteur de Jr 36 suggère que le rouleau prophétique doit être considéré comme texte d’autorité, à l’instar du livre de la Loi, décrit en 2 R 22-23.
Expérience de Dieu et expérience transcendantale chez Karl Rahner
Authors: Sendrez David
Published: October 2019

Le mot « expérience » est décisif dans la théologie de Karl Rahner et se trouve paradoxalement accolé au qualificatif « transcendantal ». Cet article tâche de démêler les rapports entre expérience transcendantale et expérience de Dieu, à partir de l’examen du plan du Traité fondamental de la foi (TFF) et de l’analyse de deux textes majeurs de l’ouvrage, la « méditation sur le mot Dieu » et « L’expérience de la Résurrection chez les premiers disciples ». L’aboutissement de ces analyses honore l’arrière-plan trinitaire et mystique de la démarche théologique du TFF.
Mystique et subjectivisation. Mystique – autonomie – foi trinitaire
Authors: Holzer Vincent
Published: October 2019

L’ouvrage fascinant de Leszek Kolakowski, Chrétiens sans Église. La conscience religieuse et le lien confessionnel au xvii e siècle , traite de la christologie de Pierre de Bérulle en la qualifiant de « mystique réifiée ». Ce faisant, Kolakowski relance le débat autour de l’interprétation d’une « théologie mystique » puissamment nourrie d’une spéculation théologique trinitaire dont il apparaît difficile de déterminer parfaitement le but. L’étude proposée consiste à apporter une contribution à ce débat complexe, en analysant la manière dont Bérulle réordonne la taxis trinitaire et radicalise l’autonomie et l’indépendance du Verbe dans sa relation conjointe au Père et à l’Esprit. Cette surprenante théologie supporte des interprétations en tension, sans qu’aucune d’elles ne puisse prétendre à s’imposer univoquement.

Published: October 2019

Education is a processor effort carried out by someone to gain knowledge, skills, and habits in life. Today education in Indonesia is much influenced by globalization and the development of technology, information, and communication (ICT). ICT has become one of the aspects that is very much considered in the world of education from now on. The use of ICT in planning, process, and evaluation of learning is a very lively discussion discussed by Indonesian education practitioners. The teacher must be able to process the development of ICT in a positive direction so that students do not forget their original culture as the Indonesian nation. many things teachers can do by using Tats in the learning process. Teachers can find more educational references, teachers can use ICT as a learning medium. By using e-learning, students will become more motivated in learning. One form of e-learning based learning is to use a 3D page flip book application. The e-book is an innovative book that is designed to produce printed books because it produces products in the form of soft and economical distribution files. The ethnic-constructivistic module developed here will use a professional 3D page flip. In this research, we will see how the implementation of e-learning-based learning, ethnoconstuctivist multimedia with module uses a 3D page flip book. In addition, in this study, it will also be seen how students' responses and motivation after learning using the 3D page flip book application.

Published: October 2019

To supplement conventional teaching methods, use of new technology have recently being adapted in the current education system. Such examples are implementing simulators and quiz kits in a classroom session to assist teachers in providing standardized evaluation or practical and more direct examples of concepts that are being taught. Additionally, the well-known issue of attracting student interest in a so-called uninteresting conventional lecture may be solved by using this technological method. The objective of this works to provide methods on developing a prototype training kit (named as e-Logic trainer kit or e-LTK) which comprises of an electronic simulator and quiz assessment module to evaluate subject knowledge on logic gates. The e-LTK is developed by using Arduino Mega 2560 as the base microcontroller, equipped with keypad and display module as the user input/output interface. The quiz assessment module contained in the prototype also allows conversion of inputs by combinatorial logic circuits into output in the form of timing diagram. This equipment enables electrical engineering students to simulate several combinations of logic circuit, reinforcing the understanding of logic circuit operation. The effectiveness of using this prototype in educational settings have been evaluated through a survey on students and instructors at Faculty of Technology in Engineering (FTK) in Universiti Teknikal Malaysia Melaka (UTeM). Response has been positive, with 60% of the correspondence has shown positive feedbacks, indicating the usefulness of the prototype kit.
Secondary prevention of hidradenitis suppurativa
Authors: Kurzen Hjalmar , Kurzen Marina
Published: October 2019

Hidradenitis suppurativa (HS) is a multifactorial disease with many facets of uncertain importance for optimal treatment and prevention. In order to explore options for secondary prevention in HS, we randomly and retrospectively selected 40 patients with HS that were analyzed on the basis of supposed trigger factors and proposed prevention measures. 67% of our HS patients were current smokers. They had started smoking on average 8 years prior to abscess formation. 35% complained of digestive problems and had tried different sorts of diet. We identified 2 cases of gluten-sensitive enteropathy, in which HS improved after introduction of gluten-free diet. In 7 further patients, introduction of low dairy/low carbohydrate diet considerably improved HS. 77.5% had never used any skin care in the intertriginous areas. Implementing secondary prevention by reducing irritation, avoiding shaving, improving skin care, performing laser epilation or applying fusidic acid/betamethasone cream led to an improvement in 62.5% of patients. We suggest a structured approach in daily practice in order to identify individual trigger factors. The crucial point for secondary prevention is the improvement of patient education.
Honeybush (Cyclopia spp.) phenology and associated arthropod diversity in the Overberg region, South Africa
Authors: Slabbert Eleonore L. , Malgas Rhoda R. , Veldtman Ruan , Addison Pia
Published: October 2019

Background: Cyclopia is endemic to regions of the Cape Floristic Region across the Eastern and Western Cape provinces of South Africa and is commonly known as honeybush. Honeybush has historically been used as an herbal tea, and has proven medicinal properties. Honeybush biomass and extracts are used in the functional foods and cosmetics sectors, both locally and overseas. The growing demand for honeybush calls for increased agricultural production and a shift away from the predominantly wild harvested supply.Objectives: The current study aimed to address the lack of baseline knowledge on honeybush phenology and its associated arthropod community to advance sustainable production of commercially valued plants in the genus.Method: The study was conducted on wild and cultivated Cyclopia species (Cyclopia maculata and Cyclopia genistoides) at respective sites in the Overberg region. Sampling took place from April 2014 to April 2015 using qualitative methods for recording seasonal honeybush phenology and suction sampling for aboveground arthropods. Focal insect taxa (Coleoptera, Hemiptera, Thysanoptera, Lepidoptera and Hymenoptera) were sorted and identified to family level and classified into functional feeding guilds.Results: Qualitative phenology observations of wild C. maculata and cultivated C. genistoides indicated a high level of congruency in seasonality of phenophase stages. Associated arthropod assemblages contained a diversity of families per functional feeding group, namely phytophagous, zoophagous and omnivorous taxa, with high seasonal variability.Conclusion: Findings highlight the complexity of ecological elements to be taken into consideration for ecologically sound honeybush cultivation. Outcomes can be applied to land management practices and governance policies promoting sustainable agroecosystems in honeybush production areas.
Invasive alien plants occurring in Lesotho: Their ethnobotany, potential risks, distribution and origin
Authors: Kobisi Khotso , Seleteng-Kose Lerato , Moteetee Annah
Published: October 2019

Background: Several recent studies have documented the ethnobotanical uses of plants used in Lesotho, in particular those used for medicinal purposes. However, these reports did not make a distinction between indigenous, naturalised or invasive alien plants. Furthermore, the existing records on the status of the occurrence of these plants in the country are not up to date.Objectives: The aim of this article is to present information on the current knowledge regarding the status of invasive alien plant species in Lesotho and to discuss their ethnobotanical uses, distribution in the country, origin and safety. We further assess the existing legislation designed to regulate the spread of such plants and make a comparison with the invasiveness and regulation of such plants in the neighbouring South Africa.Method: This article is based mainly on a literature survey of published information obtained from various databases, such as Google Scholar, Science Direct and Scopus, as well as from unpublished data such as technical reports, dissertations and theses.Results: A total of 57 species, comprising one pteridophyte, one gymnosperm and 56 flowering plants (52 dicotyledons and 4 monocotyledons) are documented. Although these plants are invasive in nature, they are utilised for a variety of purposes including food, treatment of various medical conditions, cosmetics and functional uses. However, some of the species are reported to be poisonous to both animals and humans, with a majority of the plants causing skin irritation. Most of these species are widely distributed throughout the country and most of them originated from America, Europe and Asia. Although a number of reports on the occurrence of invasive alien plants have been generated, the information therein has not yet been published.Conclusion: This study has identified knowledge gaps in terms of safety and distribution of the species, as well as shortfalls in the policies intended to regulate invasive alien species (IAS) in Lesotho. Further research in this regard is therefore recommended.
The mind’s eye: A neuro-ophthalmological perspective on Niemann-Pick type C disease
Authors: Beedasy Priyanka , Moodley Anand , Marais Adrian D.
Published: October 2019

Niemann-Pick disease type C (NPC) is a rare autosomal recessive genetic disease caused by mutations in the NPC1 and NPC2 genes with an estimated incidence of 1:120 000 live births. The clinical presentations vary across the ages. Children present with visceral symptoms related to cholesterol accumulation in the liver and adults have predominantly neuropsychiatric features such as dementia. However, vertical supranuclear gaze palsy can be present from the first year of life and is a strong feature in the diagnosis of NPC, which can be confirmed by a skin biopsy. A 36-year-old female with long-standing depression was referred for an evaluation of dystonia. She had progressive cognitive decline, dysarthria, dysphonia, dystonia of the trunk and limbs, ataxia and supranuclear gaze palsy. A similar course of illness affected her brother. Her parents were first cousins. She had positive Filipin stain of fibroblasts cultured from her skin biopsy, confirming the diagnosis of NPC. Miglustat, the approved drug for treatment, was not accessible. She had been on simvastatin since diagnosis, with a poor response, and had ongoing severe cognitive and physical disability. There are few conditions that present with neuropsychiatric symptoms and supranuclear gaze palsy. This patient had been managed as chronic depression with psychosis since her teenage years and her diagnosis was reviewed only when she had developed dystonia. Supranuclear gaze palsy is an early diagnostic clinical clue that could be present from infancy and should be sought in patients with neurocognitive presentations.
The crown of virginity, paradise regained: A study of Jerome’s ascetic exegesis in a selection of his works
Authors: Lamprecht Johanna C.
Published: October 2019

This article explores, in the first place, Jerome’s creation of pro-virginal propaganda in a selection of his treatises and letters, through the employment of scriptural justification by means of ascetic exegesis and rhetorical strategies. The study focuses, in particular, on his Epistulae 22 and 130, both addressed to virgins, and his treatise Adversus Iovinianum. Jerome interpreted and deployed carefully selected biblical texts and employed classical rhetorical conventions to construct his ascetic ideal mainly based on sexual renunciation. The article argues that by extolling the virginal body through metaphorical figurations and careful textualisation, this ‘apostle of virginity’ aimed to create, in the first instance, for ascetically minded virgins, a means of achieving perfection and union with God, and receiving the awards of heaven. The analysis of the selected works and of Jerome’s ascetic exegesis, however, also reveals some significant markers, indicating his own carefully disguised quest for personal redemption and regaining paradise.
Advancing justice in the search for peace: An exegetical study of Micah 6:8 as a recipe for peace in Africa
Authors: Tushima Cephas T.A.
Published: October 2019

Peace has been elusive to the greater part of the African continent. For peace to thrive in any place, certain fundamentals for societal cohesion must be entrenched in its social fabric. This essay studies Micah 6:8, with the aim of identifying such important biblical fundamental principles for societal peace. This article employs rhetorical analysis with the historical grammatical method of textual analysis to exegete Micah 6:8. The article begins with an exploration of the biblical concepts of peace and justice. It then exegetes Micah 6:8 in its historical and literary contexts, explaining the three critical demands of YHWH in the verse, namely, to act justly (both in the judicial administration of justice and in the maintenance of right relationships in the community), to love mercy (highlighting loyal loving commitment to God and the brotherhood in covenant) and to walk humbly with God (a basic call to discipleship). This is followed by an analysis of the African crisis situation, pointing out the similarities between the socio-economic conditions of Micah’s times and ours. Ultimately, these biblical principles are interconnected with the African situation, showing how the implementation of Micah’s justice agenda (employing the retributive, restorative and redistributive elements of justice) is a recipe for peace in Africa.Intradisciplinary and/or interdisciplinary implications: This essay challenges the approaches towards the pursuit of peace in Africa and calls for a biblical justice approach for finding peace. It works across the disciplinary fields of biblical studies, biblical theology, public theology and social justice.

A COMPARISON BETWEEN EXPERIENTIAL AND ECMWF REANALYZED CONDENSED MOISTURE PROFILE OVER THE NORTHEASTERN SPHERE
Authors: Wang X. Z. , Hu B. H. , Wang J. , Huang H. , Zhang W. J. , Lin F. K.
Published: October 2019

Abstract. Base on January and July 4-times daily ECMWF Interim data from 2009 to 2018 over the Northeast Sphere (0–180E,0–90N), the condensed moisture profile of experiential methods and that of ECMWF analysis are compared. The result shows that, the meridional-height distribution of mean cloud condensed moisture has a maximum slab spreading near ground in the Arctic region in July, and the maximum takes a circular shape at 700 hPa above 30N latitude in January. The distribution feature unlike the universal profile, it distributes in a single or double peak function manner, instead of a constant value. The quick decreasing level height and thickness varies with latitude, especially in January. The second experiential profile concerning warm cloud assumes air parcel lifting adiabatically, the liquid water path (LWP) is compared for general information. The result shows that the experiential LWP is much larger than that of the reanalysis by 1 to 2 order, decreasing with latitudes. The possible reason of LWP difference is from the critic water content value of cloud boundary identification. If the value is small, the thickness of warm cloud will be large, temperature and pressure at the cloud base are both large too, results in a larger LWP. These results will enrich the knowledge of the condensed moisture characteristics of ECMWF reanalysis and the experiential moisture profile methods.

In order to evaluate the accuracy of three AATSR aerosol optical depth (AOD) datasets, and to improve the spatial coverage and accuracy of AATSR AOD dataset, this study completed two works: the first part is validated the accuracy of three AOD datasets; the second part is fused three AATSR AOD datasets based on uncertainty of each dataset. After comparing with AERONET and CARSNET ground-based data over China, results show that the root-mean-square error (RMSE) for ADV v3.11, ORAC v4.10, SU v4.32 and fused AOD are 0.22, 0.17, 0.18, 0.17 respectively.

Abstract. We projected incident surface solar radiation (SSR) over China in the middle (2040–2059) and end (2080–2099) of the 21st century in the Representative Concentration Pathway (RCP) 8.5 scenario using a multi-model ensemble derived from the weighted average of seven global climate models (GCMs). The multi-model ensemble captured the contemporary (1979–2005) spatial and temporal characteristics of SSR and reproduced the long-term temporal evolution of the mean annual SSR in China. However, it tended to overestimate values compared to observations due to the absence of aerosol effects in the simulations. The future changes in SSR showed increases over eastern and southern China, and decreases over the Tibetan Plateau (TP) and northwest China relative to the present day. At the end of the 21st century, there were SSR increases of 9–21 W m−2 over northwest, central, and south China, and decreases of 18–30 W m−2 over the TP in June–July–August (JJA). In northeast China, SSR showed seasonal variation with increases in JJA and decreases in December–January–February. The time series of annual SSR had a decreased linear trend for the TP, and a slightly increased trend for China during 2006–2099. The results of our study suggest that solar energy resources will likely decrease in the TP under future climate change scenarios.

Abstract. The Advanced Himawari Imager (AHI) onboard Himawari-8, a next-generation geostationary meteorological satellite, provided firstly the full-disk aerosol observations every 10 min at sub-kilometer spatial resolution(5 km). This is responsible for retrieving the ground-level particulate matter of fewer than 2.5 micrometers and improving assimilation model. However, the representativeness of AHI L3 hourly Aerosol Optical Thickness (AOT) products remains unclear under different air quality conditions, Especially, over frequently polluted urban areas that feature complex surface characteristics and aerosol models. In this study, One-to-one comprehensive comparisons were conducted to evaluate the performance of three types of AHI L3 AOT products (version 3.0) based on the Aerosol Robotic NETwork (AERONET) aerosol measurements over Beijing. The overall comparisons of AHI and ground AOTs show the AHI merged AOT perform best, which the R is 0.87, RMSE is 0.25 and 52.5% of retrievals fall within the envelope of Expect Error (EE, ±(0.05 + 0.2 * AOTground)). For the different primary pollutants, the results suggested the three types AHI hourly AOT products are more suitable for the fine particulate matters (PM2.5) retrievals, especially the merged AOT with 0.87 of R, 0.29 of RMSE and 58.8% of within EE. Furthermore, when the slight and moderate pollution happened over Beijing, the AHI hourly AOT products perform well. And when the heavy pollution happened, the performance of the AHI merge AOT and L2 mean AOT is better. a case during low to high pollution suggested that AHI merged AOT can capture the similar spatial pattern to the MODIS (Deep Blue) DB or (Dark Target) DTDB merged AOT and has good consistency with ground-based air quality monitoring. These results demonstrate the AHI hourly merged AOT is a promising aerosol retrieval for air quality.

Abstract. Cirrus plays an important role in atmospheric radiation. It affects weather system and climate change. Satellite remote sensing is an important kind of observation for cloud. As a passive remote sensing instrument, large bias was found for thin cirrus cloud top height retrieval from MODIS (Moderate Resolution Imaging Spectroradiometer). Comparatively, CALIOP (Cloud-Aerosol Lidar with Orthogonal Polarization) aboard CALIPSO (Cloud–Aerosol Lidar and Infrared Pathfinder Satellite Observation) which is an active remote sensing instrument can acquire more accurate characteristics of thin cirrus cloud. In this study, CALIPSO cirrus cloud top height data was used to correct MODIS cirrus cloud top height. The data analysis area was selected in Beijing-Tianjin-Hebei region and data came from 2013 to 2017. Linear fitting method was selected based on cross-validation method between MODIS and CALIPSO data. The results shows that the difference between MODIS and CALIPSO changes from −3~2 km to −2.0~2.5 km, and the maximum difference changes from about −0.8 km to about 0.2 km. In the context of different vertical levels and cloud optical depth, MODIS cirrus cloud top height is improved after correcting, which is more obvious at lower cloud top height and optical thinner cirrus.

Abstract. In order to study the on-board processing technology of meteorological satellites, a decision tree cloud detection algorithm is proposed by taking FY-4A satellite data as an example. According to the channel setting of the Advanced Geosynchronous Radiation Imager (AGRI) on FY-4A satellite, the 0.65 μm, 1.375 μm, 3.75 μm, and 10.7 μm bands are selected as the cloud detection channels, and the reflectance, brightness temperature or bright temperature difference of the four channels are used as the cloud detection indicators, the thresholds of the four cloud detection indicators are obtained through statistics. On this basis, the decision tree cloud detection model is constructed and validated using FY-4A satellite data. The results show that the algorithm is simple, convenient and efficient, and the overall effect of cloud detection is good. It is an effective way for meteorological satellite cloud detection on-board processing technology.
PROCESSING JUMP POINT OF LIDAR DETECTION DATA AND INVERSING THE AEROSOL EXTINCTION COEFFICIENT

Abstract. For a long time, the research of the optical properties of atmospheric aerosols has aroused a wide concern in the field of atmospheric and environmental. Many scholars commonly use the Klett method to invert the lidar return signal of Mie scattering. However, there are always some negative values in the detection data of lidar, which have no actual meaning，and which are jump points. The jump points are also called wild value points and abnormal points. The jump points are refered to the detecting points that are significantly different from the surrounding detection points, and which are not consistent with the actual situation. As a result, when the far end point is selected as the boundary value, the inversion error is too large to successfully invert the extinction coefficient profile. These negative points are jump points, which must be removed in the inversion process. In order to solve the problem, a method of processing jump points of detection data of lidar and the inversion method of aerosol extinction coefficient is proposed in this paper. In this method, when there are few jump points, the linear interpolation method is used to process the jump points. When the number of continuous jump points is large, the function fitting method is used to process the jump points. The feasibility and reliability of this method are verified by using actual lidar data. The results show that the extinction coefficient profile can be successfully inverted when different remote boundary values are chosen. The extinction coefficient profile inverted by this method is more continuous and smoother. The effective detection range of lidar is greatly increased using this method. The extinction coefficient profile is more realistic. The extinction coefficient profile inverted by this method is more favorable to further analysis of the properties of atmospheric aerosol. Therefore, this method has great practical application and popularization value.

Abstract. The chemical composition of aerosols was investigated using regular environmental air quality observation, a single particle aerosol mass spectrometer (SPAMS 0515) and an ambient ion monitor (URG 9000D) in Xiamen in 2018. The results showed that the annual average mass concentrations of PM2.5 was 22 μm/m3, and concentrations of water-soluble inorganic ions was 9.94 μm/m3 which accounted for 45.2% of PM2.5. SO42−, NO3− and NH4+ were main components of secondary reactions which contributed more than 77 percent of water-soluble inorganic ion concentration. As a coastal city, Cl− and Na+ contributed 13.9 percent of water-soluble inorganic ion concentration. Based on single particle aerosol mass spectrometer analysing, mobile sources emission was the most important sources of particle matter which contributed over 30%.

Identifying students’ learning styles is advantageous for both teachers and students. Awareness of students’ learning styles allows teachers to plan lessons to reach each student in the classroom by providing proper activities and classroom materials that suit every individual. Furthermore, students can raise their own awareness of the learning process and maximize their opportunities to learn by knowing their preferred learning styles. Using the Perceptual Learning Style Preference Questionnaire, this study aims to investigate Saudi EFL students’ preferred learning styles and explore whether these learning styles are affected by students’ academic majors. The participants were 120 Saudi students at a private college in four different majors. The results show that the kinaesthetic learning style is the most commonly preferred learning style among students of all majors. Based on the findings, pedagogical implications and directions for further research are highlighted.
