We combine 126 new galaxy-O vi absorber pairs from the CGM2 survey with 123 pairs drawn from the literature to examine the simultaneous dependence of the column density of O vi absorbers (N

O VI) on galaxy stellar mass, star-formation rate, and impact parameter. The combined sample consists of 249 galaxy-O vi absorber pairs covering z = 0–0.6, with host galaxy stellar masses M
* = 107.8–1011.2
M

⊥ = 0–400 proper kiloparsecs. In this work, we focus on the variation of N

O VI with galaxy mass and impact parameter among the star-forming galaxies in the sample. We find that the average N

O VI within one virial radius of a star-forming galaxy is greatest for star-forming galaxies with M
* = 109.2–1010
M
⊙. Star-forming galaxies with M

M
⊙ can explain most O vi systems with column densities greater than 1013.5 cm−2. Sixty percent of the O vi mass associated with a star-forming galaxy is found within one virial radius, and 35% is found between one and two virial radii. In general, we find that some departure from hydrostatic equilibrium in the CGM is necessary to reproduce the observed O vi amount, galaxy mass dependence, and extent. Our measurements serve as a test set for CGM models over a broad range of host galaxy masses.
The Evolution of the Orbital Lightcurve of Hercules X-1 with 35 Day Phase
Authors: Wang Yuyang , Leahy Denis
Published: March 2022

Hercules X-1/HZ Hercules (Her X-1/HZ Her) is an X-ray binary monitored by multiple X-ray missions since the last century. With the abundance of long-term observations, we present a complete set of orbital lightcurves of Her X-1/HZ Her during the six states of the 35 day cycle in multiple energy bands. These illustrate in detail the changing lightcurve caused by the rotating twisted-tilted accretion disk surrounding the neutron star. The orbital lightcurves during the main high state are analyzed in 0.05 35 day phase intervals. These show the regular occurrence of pre-eclipse dips that march to earlier orbital phases as the 35 day phases increase. From the multiband lightcurves, we derive the time-average orbital phase dependence of column density for photoelectric absorption and energy-independent transmission as a function of 35 day phase. The X-ray lightcurves during low states are similar in shape to the optical low-state lightcurve, but X-ray leads optical by ≃0.04–0.08 in orbital phase.

We report on observations of the candidate Be/X-ray binary (BeXRB) IGR J18219−1347 with the Swift/X-ray Telescope, the Nuclear Spectroscopic Telescope ARray, and the Neutron Star Interior Composition Explorer during Type-I outbursts in 2020 March and June. Our timing analysis revealed the spin period of a neutron star with P
spin = 52.46 s. This periodicity, combined with the known orbital period of 72.4 days, indicates that the system is a BeXRB. Furthermore, by comparing the spectral energy distribution of the infrared counterpart to that of known BeXRBs, we confirm this classification and set a distance of approximately 10–15 kpc for the source. The broadband X-ray spectrum (1.5–50 keV) of the source is described by an absorbed power law with a photon index Γ ∼ 0.5 and a cutoff energy at ∼13 keV.
A Giant Shell of Ionized Gas Discovered near M82 with the Dragonfly Spectral Line Mapper Pathfinder

Published: March 2022

We present the discovery of a giant cloud of ionized gas in the field of the starbursting galaxy M82. Emission from the cloud is seen in Hα and [N ii] λ6583 in data obtained though a small pathfinder instrument used to test the key ideas that will be implemented in the Dragonfly Spectral Line Mapper, an upcoming ultranarrow-bandpass imaging version of the Dragonfly Telephoto Array. The discovered cloud has a shell-like morphology with a linear extent of 0.°8 and is positioned 0.°6 northwest of M82. At the heliocentric distance of the M81 group, the cloud’s longest angular extent corresponds to 55 kpc and its projected distance from the nucleus of M82 is 40 kpc. The cloud has an average Hα surface brightness of 2 × 10−18

. The [N ii] λ6583/Hα line ratio varies from [N ii]/Hα ∼ 0.2 to [N ii]/Hα ∼ 1.0 across the cloud, with higher values found in its eastern end. Follow-up spectra obtained with Keck LRIS confirm the existence of the cloud and yield line ratios of [N ii] λ6583/Hα = 0.340 ± 0.003 and [S ii] λλ6716, 6731/Hα = 0.64 ± 0.03 in the cloud. This giant cloud of material could be lifted from M82 by tidal interactions or by its powerful starburst. Alternatively, it may be gas infalling from the cosmic web, potentially precipitated by the superwinds of M82. Deeper data are needed to test these ideas further. The upcoming Dragonfly Spectral Line Mapper will have 120 lenses, 40× more than in the pathfinder instrument used to obtain the data presented here.
A Statistical View of the Stable and Unstable Roche Lobe Overflow of a Tertiary Star onto the Inner Binary in Triple Systems
Authors: Hamers Adrian S. , Glanz Hila , Neunteufel Patrick
Published: March 2022

In compact stellar triple systems, an evolved tertiary star can overflow its Roche lobe around the inner binary. Subsequently, the tertiary star can transfer mass to the inner binary in a stable manner, or Roche lobe overflow (RLOF) can be unstable and lead to common-envelope (CE) evolution. In the latter case, the inner binary enters the extended envelope of the tertiary star and spirals in toward the donor’s core, potentially leading to mergers or ejections. Although studied in detail for individual systems, a comprehensive statistical view on the various outcomes of triple RLOF is lacking. Here, we carry out 105 population synthesis simulations of tight triples, self-consistently taking into account stellar evolution, binary interactions, and gravitational dynamics. Also included are prescriptions for the long-term evolution of stable triple mass transfer, and triple CE evolution. Although simple and ignoring hydrodynamic effects, these prescriptions allow for a qualitative statistical study. We find that triple RLOF occurs in ∼0.06% of all triple systems. Of these 0.06%, ∼64% of cases lead to stable mass transfer, and ∼36% to triple CE evolution. Triple CE is most often (∼76%) followed by one or multiple mergers in short succession, most likely an inner binary merger of two main-sequence stars. Other outcomes of triple CE are a binary+single system (∼23%, most of which do not involve exchange interactions), and a stable triple (∼1%). We also estimate the rate of type Ia supernovae involving white dwarf mergers following triple RLOF, but find only a negligible contribution.
Distribution and identification of the species in the genus Helicops Wagler, 1830 (Serpentes, Colubridae, Xenodontinae)
Authors: Schöneberg Yannis , Köhler Gunther
Published: March 2022

The aquatic snakes of the genusHelicopsare widely distributed throughout northern South America, but understudied concerning some aspects, including morphological traits and distribution. The most recent publication that provided an identification key to all species ofHelicopsis over 50 years old. This key is of limited value today since it includes taxa no longer recognised and lacks 8 of the 19 species currently recognised. There never was a publication trying to summarise distributional and morphological information of all species ofHelicops. Most knowledge of these species is distributed throughout many small publications, such as short observation notes.

Here, we present distribution maps (point records), an identification key and comments on identification for all species in this genus. We base our results on a comprehensive literature review of over 300 scientific publications and own examinations. Our examinations comprise 190 specimens of 10 of the 19 currently recognised species and oneHelicopssp. We report range extensions for the speciesH. danieli,H. infrataeniatus,H. leopardinus,H. pastazaeandH. polylepis.
An Overview of Enzyme Replacement Therapy for Lysosomal Storage Diseases
Authors: Bailey Laurie
Published: March 2022

The lysosomal storage diseases (LSDs) are a group of disorders heralding in a new era in the treatment of genetic diseases. Enzyme replacement therapy (ERT) moves the treatment of these disorders from symptomatic management to therapeutic interventions. ERT is not a cure for these disorders, but it can greatly modify or attenuate the phenotype. Treatment for LSDs is lifelong and the diseases affect multiple organ systems. It is possible that nurses in almost every specialty will encounter a patient with one of these conditions. Therefore knowledge of the conditions, the benefits and limitations of ERT, and its effective management are becoming more important for all nurses. This article will describe several LSDs, namely Gaucher disease, Fabry disease, Pompe disease, and the mucopolysaccharidoses. Each disease pathology, signs and symptoms, and effectiveness of ERT treatment will be discussed, as well as the administration of ERT, common side effects, management of the side effects, and nursing implications. Additionally drug costs and insurance concerns will be highlighted.
Genetic and Genomic Healthcare: Ethical Issues of Importance to Nurses
Authors: Lea Dale
Published: March 2022

The complete sequencing of the human genome in 2003 has opened doors for new approaches to health promotion, maintenance, and treatment. Genetic research is now leading to a better understanding of the genetic components of common diseases, such as cancer, diabetes, and stroke, and creating new, gene-based technologies for screening, prevention, diagnosis, and treatment of both rare and common diseases. Nurses are on the forefront of care, and therefore will participate fully in genetic-based and genomic-based practice activities such as collecting family history, obtaining informed consent for genetic testing, and administering gene-based therapies. This new direction in healthcare calls for all nurses to be able to effectively translate genetic and genomic information to patients with an understanding of associated ethical issues. This article will present six genetic and genomic healthcare activities involving ethical issues of importance to nurses. For each activity discussed, an overview of current and/or emerging ethical issues will be presented. Approaches nurses can use to integrate comprehensive and current knowledge in genetics and genomics into their practice to most fully meet the needs of their patients, families, and society will also be described.
The Cultural Lens of Genomics
Authors: Paniagua Carmen , Taylor Robert
Published: March 2022

Cultural diversity continues to increase in many countries around the world. In the United States this diversity has increased significantly over the past decade. It is essential that healthcare professionals provide genomic-focused care in a culturally sensitive manner, recognizing and respecting the cultural values and beliefs of each and every patient. The purpose of this article is to increase healthcare providers' awareness of basic cultural values that can influence the decisions made by members of diverse patient populations. This article will describe the concepts of culture, race, ethnicity, ethno-culture, and genetic diseases in specific populations. In addition, it will discuss ethno-cultural values of Hispanics, African Americans/Blacks, Native American Indians or Alaskan Natives, and Native Hawaiians or other Pacific Islanders that may influence patient and family responses to genomic healthcare, noting the need to incorporate an ethno-cultural lens in assessing patients and providing genomic interventions for them. The article will conclude with recommendations for providing care to diverse populations.
Critical Need to Address Accuracy of Nurses’ Diagnoses
Authors: Lunney Margaret
Published: March 2022

Studies published from 1966 to 2006 describe how nurses’ interpretations of clinical data vary widely, thus significant percentages of nurses’ diagnoses may be of low accuracy. This is important because data interpretations, or diagnoses, serve as the basis for selection of interventions and the subsequent achievement of patient outcomes. Accuracy of nurses’ diagnoses is defined as a rater’s judgment of the match between a diagnostic statement and patient data. Low accuracy can lead to wasted time and energy, harm to patients, absence of positive outcomes, and patient and family dissatisfaction. The purpose of this article is to appeal to nurses in both practice and education to address the accuracy of nurses’ diagnoses. This appeal is based on three factors: (a) research evidence indicates the need for greater consistency among nurses in making nurses diagnoses, (b) accuracy of nurses’ diagnoses will always be an issue of concern because diagnosis in nursing is complex, and (c) with implementation of electronic health records, the degree of accuracy of nurses’ diagnoses will have broad-based implications. In this article, the need for nurses to be accountable for addressing diagnostic accuracy is explained and strategies to improve accuracy related to the diagnostician, the diagnostic task, and the situational context are recommended. Some of these strategies include a greater focus on educational methods and content for development of nurses as diagnosticians, adoption of partnership models of nurse-patient relationships, an increase in opportunities for critical thinking and clinical decision making, selection of software with appropriate structures and content libraries, and a change in health care policies.
Nurses on the Move: Historical Perspective and Current Issues
Authors: Kingma Mireille
Published: March 2022

The number of international migrants on the move each year continues to increase. Women migrants are becoming agents of economic change as they enter the international labor market and participate in a new distribution of global wealth. Professionally active nurses are important players in an increasingly competitive, global labor market. Thousands of nurses migrate each year in search of better pay and working conditions, career mobility, professional development, a better quality of life, personal safety, or sometimes just novelty and adventure. In this article, the author looks at the characteristics and the effects of nurse migration, addresses the factors driving international nurse mobility, and discusses current issues regarding nurse migration. The author advises that rather than focusing on national and international recruitment, serious attention be given to retention strategies to successfully address the critical shortage of health professionals willing to remain in active practice.

Published: March 2022

This paper documents an exploratory meeting organized by the Pan American Health Organization, that gathered nurses from countries of Latin America, who identified the shortage and migration tendencies as an emerging area in need of investigation. The exploratory meeting was conducted under the direction of the Regional Advisor on Nursing and Allied Health Personnel at the Pan American Health Organization in collaboration with the nursing leadership of Latin America. Fifteen of the 19 Latin American Countries participated in the meeting including: Argentina, Bolivia, Brazil, Chile, Colombia, Dominican Republic, El Salvador, Ecuador, Guatemala, Honduras, Mexico, Panama, Peru, Uruguay, and Venezuela. All agreed that documentation was needed concerning the shortage and migration of nurses including its causes and effects, the distribution of professional nurses, and available public policies to support the needs of professional nurses in Latin America.
Globalization of Higher Education in Nursing
Authors: Baumann Andrea , Blythe Jennifer
Published: March 2022

The demand for higher education has increased worldwide and the response has been an impressive expansion of educational offerings both within and across countries. The purpose of this manuscript is to emphasize the necessity of common educational standards for nurses in a globalized world. Common standards are crucial in regulated professions, such as nursing, in which lives depend on the possession of specific competencies. This article defines and describes globalization and the internationalization of education, including nursing education, discusses the exporting of nursing education, identifies the challenges and current solutions related to nurse migration, and presents current standards and future trends in harmonizing nursing education internationally.

Published: March 2022

The national spotlight on the Registered Nurse shortage has helped to generate strong interest in nursing careers among those new to the workforce and those seeking a career change. With salaries climbing, opportunities expanding, and the demand for nursing services on the rise, now is an exciting time to join the nursing profession. This article discusses the traditional entry points into Registered Nursing, specifically Baccalaureate Degree Programs, Associate Degree Programs, and Diploma Programs, as well as emerging routes, which include entry-level master’s programs, community college-based baccalaureate programs, and degree completion programs for Licensed Practical Nurses and other allied health providers. With multiple opportunities for progression to advanced degrees in nursing, the authors also touch on graduate education options including online programs, baccalaureate to doctoral programs, along with Clinical Nurse Leader and Doctor of Nursing Practice programs.
Disaster Readiness: A Community - University Partnership
Authors: Adams Lavonne , Canclini Sharon
Published: March 2022

The aftermath of Hurricane Katrina heightened public awareness of vulnerability to disasters and the need for disaster preparedness. Disaster-preparedness studies tend to focus on formal systems of healthcare and frontline healthcare providers, such as hospital personnel, public health staff, or emergency medical services workers who care for community members having serious injuries. Community members who are not seriously injured, however, are expected to care for themselves immediately after a disaster occurs. To date, little is known about the community members’ level of preparedness to meet their basic, self-care needs immediately following a disaster or the effectiveness of such preparedness education for the community. Yet, the health and safety of the general community following a disaster depends on its citizens’ level of preparedness to meet the needs not only of the seriously injured, but also of those with minimal or no injuries. Schools of nursing can play a vital role in enhancing the general public’s self-care ability following a disaster. The authors of this article describe a clinical learning experience that involved nursing students in a health education project related to one community’s desire to better prepare themselves for future disasters. A participatory action research (PAR) approach, which included collaboration with a community, involvement of the target community, and project evaluation, provided a framework for this disaster-preparedness initiative.
Littératures en langues africaines
Authors: Baumgardt Ursula
Published: March 2022

Le Rwanda jouit d’une unité linguistique sans pareille et dispose d’une littérature orale connue, grâce notamment aux travaux d’Alexis Kagame qui a révélé au monde la richesse de la poésie dynastique, pastorale et guerrière. Les récits historiques et populaires, les contes, les proverbes et devinettes ont fait l’objet de plusieurs études et de quelques traductions en langues européennes. La littérature écrite aussi, entre autres les poèmes de quelques grands noms comme Alexis Kagame et Cyprien Rugamba, forment le corpus de quelques thèses et mémoires. Certains connaissent aussi F.-X. Gasimba qui a gagné à plusieurs reprises le Prix Kadima de l’OIF. Mais c’est surtout la littérature sur le génocide qui a fait exploser le champ littéraire rwandais par des publications essentiellement en français (voir F. Lagarde, 2014). Dans cet ensemble hétérogène, la littérature en kinyarwanda reste la mieux représentée, mais bien que relativement abondante, elle n’est diffusée ni enseignée dans les écoles et reste donc ignorée du grand public. Assez dynamique dans les années 1970-1980, elle a toujours été portée, sur le plan de la diffusion, par des bénévoles comme l’Église catholique qui a créé les Éditions rwandaises et le club Rafiki connu surtout pour la diffusion de pièces de théâtre. Après 1994, l’Association des écrivains Rwandais (IBARWA) a également joué un rôle capital dans la diffusion des œuvres littéraires en kinyarwanda. En dehors de ces quelques initiatives, le pays ne compte aucune maison d’édition classique ou numérique. Les auteurs doivent publier à leur propre compte. Il est clair que dans un tel climat d’indifférence, l’on ne peut évoquer la critique de cette littérature. Des quelques concours connus et organisés sur le territoire national, seul celui de 1971 avait pour objectif de la promouvoir, de même que celui organisé par sur le théâtre radiophonique l’ORINFOR (Office rwandais d’information) dès 1984, mais abandonné dix ans après. C’est donc une littérature qui parvient à exister malgré un contexte défavorable : absence de structure éditoriale et de réseau de distribution (deux petites librairies : Ikirezi et Caritas), une littérature inconnue du public parce que même là où elle est « enseignée », elle n’est pas disponible (seule la bibliothèque universitaire de Butare en possède quelques volumes).
Des scénarios énergétiques pour conjuguer soutenabilité et justice sociale
Authors: Marignac Yves , Gaudillière Jean-Paul
Published: March 2022

Depuis plus de vingt ans, l’association négaWatt fait figure de référence dans le paysage écologiste français. En donnant à voir des scénarios concrets et documentés sur les conséquences environnementales des politiques énergétiques et de la surconsommation énergétique en France, l’association entend réagir aux programmes initiés par le gouvernement et réorienter le débat public. Fondé sur une réflexion alliant sobriété, intelligence des usages et efficacité technique, négaWatt promeut les énergies renouvelables et l’idée d’une soutenabilité globale ; l’association élargit aujourd’hui son champ d’action en intégrant des questions d’ordre social, telles que l’emploi. Les derniers scénarios livrés présentent systématiquement une évaluation économique, allant jusqu’à proposer de véritables projets de société qui se confrontent à ceux du mouvement social, comme en témoigne la récente crise des Gilets jaunes.
À chaque crise suffit sa dette
Authors: Bourgine Xavier
Published: March 2022

Cet article discute de l’impact de mesures radicales de politique monétaire (annulation de dette ou monnaie hélicoptère) sur le capital des banques centrales et les risques que de telles mesures feraient peser sur leur indépendance et leur capacité à remplir leur mandat. A partir de quelques exercices empiriques, nous montrons qu’une annulation de dette publique détenue par l’Eurosystème, même de petite ampleur, prendrait beaucoup de temps à être absorbée par les profits habituels de l’Eurosystème, même si une dégradation du capital de la banque centrale ne mène pas nécessairement à de l’inflation, du moment que l’autorité monétaire conserve sa capacité à détruire la monnaie. Il est ainsi possible d’imaginer une banque centrale émettant une fraction des réserves sous forme de monnaie hélicoptère et le reste sous forme d’opérations conventionnelles. Le coût politique d’une telle opération apparaît cependant élevé à l’heure actuelle en zone euro. JEL : E4, E5, E6, H6
Confiance et épargne : un bilan de la littérature
Authors: Brookes Kevin , Facchini François
Published: March 2022

Cet article rend compte du rôle de plus en plus important que joue la confiance dans l’explication du volume et de la structure de l’épargne des ménages. Il s’articule autour de trois littératures qui s’ignorent : la macroéconomie de l’épargne, l’économie des institutions et l’économie de la confiance. Le concept de confiance est le mieux placé pour unifier ces trois pôles de la littérature sur les déterminants de l’épargne. Elle introduit dans l’explication de la dynamique une dimension éminemment subjective qui peut expliquer, d’une part, pourquoi les tests empiriques ont des résultats plutôt ambigus et confirmer d’autre part qu’en sciences sociales ce ne sont pas les faits objectifs, bruts qui sont importants, mais les faits perçus à travers les croyances des agents. L’article examine la relation théorique entre, d’un côté, la confiance en soi, la confiance dans les autres, la confiance dans les institutions, et de l’autre le comportement d’épargne. L’examen des articles empiriques prenant en compte cette dimension subjective fournit des résultats prometteurs. Les individus confient leur épargne sur la base des représentations qu’ils ont d’eux-mêmes, des autres et des institutions. Plus ils ont confiance, plus ils acceptent d’épargner dans des institutions financières et plus ils acceptent de prendre des risques avec leurs placements. Cet article se conclut par une discussion sur les conséquences que ces résultats ont sur la recherche en science économique et sur la détermination des politiques publiques susceptibles d’augmenter le volume d’épargne et de rendre sa structure plus efficiente.

La Revue d’Économie politique et la colonisation de l’Afrique de l’Ouest (1887-1920)
Authors: Roudaire Raphaël , Zouache Abdallah
Published: March 2022

L’article interroge le traitement de la colonisation de l’Afrique de l’Ouest par la Revue d’Économie Politique entre 1887 et 1920. Notre contribution repose sur trois résultats originaux. Premièrement, nous avons trouvé que la colonisation de l’Afrique de l’Ouest est régulièrement débattue, surtout à travers les chroniques et les bulletins bibliographiques, par les économistes phares de la revue, mais aussi par des non-économistes. Deuxièmement, l’analyse économique de la colonisation est construite à partir de présupposés racistes. Troisièmement, malgré une réticence vive quant au rôle du politique dans la colonisation économique, l’État est vue comme l’acteur principal de la colonisation car il doit sécuriser la propriété foncière, assurer la stabilité politique, promouvoir le commerce colonial avec la métropole afin de garantir l’investissement privé. La colonisation économique ne peut provenir des entreprises, dans le statut le plus souvent discuté, celui des compagnies privilégiées, car celles-ci mettent en péril la souveraineté nationale.

Quelques réflexions sur la légitimité du juge de Strasbourg
Authors: Ravarani Georges
Published: March 2022

Le concept protéiforme de légitimité du juge désigne autant sa légitimité « légale » que sa légitimité « par adhésion ». La légitimité du juge de Strasbourg a une dimension individuelle, visant son statut et l’exercice de ses fonctions, et collective, concernant l’efficacité de la Cour, sa mission de développer les droits de l’homme dans le respect de son rôle subsidiaire par rapport aux autorités nationales. Il se pose par ailleurs la question de possibles réformes pouvant renforcer la légitimité de la Cour.

L’enseignement à distance : l’oubli des corps au travail
Authors: Ganem Valérie , Perez Gabriel , Rebeyrat Jean-François
Published: March 2022

Cet article se propose d’analyser les conséquences du travail à distance dans les métiers de l’enseignement où la « classe virtuelle » s’est substituée à la « classe réelle ». À partir d’une description inspirée du sosie d’un professeur de philosophie, les auteurs interrogent la disparition des corps dans ce contexte. S’appuyant sur les analyses du travail vivant développées par la psychodynamique du travail et la phénoménologie de Michel Henry, les auteurs mettent en évidence les différences qui affectent « l’activité subjectivante » (Böhle et Milkau) de l’enseignant, lorsqu’il transite d’un contexte où le corps est d’abord présent, avant de s’exporter dans un environnement où il n’est plus qu’une image.

Immune checkpoint genes (ICGs) have recently been proven to perform instrumental functions in the maintenance of immune homeostasis and represent a promising therapeutic strategy; however, their expression patterns and prognostic values are not fully elucidated in hepatocellular carcinoma (HCC). In this investigation, we focused on establishing and validating a prognostic gene signature to facilitate decision-making in clinical practice. Clinical information, as well as transcriptome data, was obtained from the Cancer Genome Atlas (TCGA) and International Cancer Genome Consortium (ICGC) database. Univariate Cox regression and least absolute shrinkage and selection operator (LASSO) Cox method were employed to build a multi-gene signature in the TCGA database, while the ICGC database was used for validation. Subsequently, utilizing the six-gene signature, we were able to categorize patients into high- and low-risk groups. In two cohorts, survival analysis findings revealed a dismal outlook for the high-risk group. The receiver operating characteristic curves were utilized to estimate the gene signature's prediction ability. Moreover, correlation analysis showed high-risk group was linked to advanced pathological stage, infiltration of immune cells and therapeutic response. In summary, this unique gene profile might serve not only as a useful prognostic indicator but also as a marker of therapy responsiveness in HCC.
Le travail de l’histoire

Published: March 2022

Qu’est devenu aujourd’hui le « métier d’historien » dont parlait Marc Bloch ? En suivant le fil d’une expérience individuelle, ce livre s’interroge sur le travail de l’histoire, entendu dans un double sens. C’est d’abord le travail sur l’histoire, comme matériau de recherche, qui pose des questions intellectuelles mais aussi pratiques. Comment devient-on chercheur en histoire ? Que signifie lire, écrire, éditer des textes quand on est historien ? Quels sont les enjeux de l’enseignement de l’histoire ? Pourquoi participer à l’évaluation ou à l’administration au sein des institutions universitaires ? Qu’implique le fait d’intervenir dans la sphère publique ? Ces questions font le quotidien de l’historien autant, voire plus, que la fréquentation des archives et des bibliothèques. Mais, en filigrane, le travail de l’histoire désigne aussi, dans un sens qui mêle les dimensions personnelle et professionnelle, l’histoire au travail. Non seulement l’histoire comme flux temporel, qui transforme les êtres et les choses, mais aussi comme discipline, qui produit des effets sur celui qui la pratique et qui est, en retour, travaillé par cette histoire.
Habitat expansion of a tropical chironomid by seasonal alternation in use of littoral and profundal zones

The consistent warming of tropical lakes at all depths causes rapid development and long persistence of seasonal hypoxia in the hypolimnion, which greatly reduces the biodiversity of hypolimnetic benthic invertebrates. Full mixing of the water column in a typically annual cool-season creates a benthic habitat suitable for invertebrates but offers little time for colonization before the return of anoxia. In Lake Alchichica, Mexico, the endemic midge Chironomus alchichica has evolved a life cycle consisting of reproduction in waters of the littoral zone, which is suboptimal for development, followed by colonization of the hypolimnetic benthic zone during its oxic phase. As shown by the sampling of both littoral and benthic habitats over an annual cycle, the development of Ch. alchichica in the profundal zone is favoured by minimal competition (only one other invertebrate species present) and no significant predation. The rapid maturation of the midge leads to a high density of pupation before the seasonal anoxia.

Áp lực artesian từ tầng chứa nước ảnh hưởng đáng kể đến ứng xử của lớp đất yếu như quá trình cố kết và sự ổn định trong nền. Việc sử dụng các lời giải giải tích để xem xét ảnh hưởng của áp lực artesian đến quá trình phân tích ổn định còn khó khăn trong thực tế. Do đó, bài báo này sử dụng phương pháp số để đánh giá ứng xử của nền đường trên đất yếu chịu áp lực artesian, trong đó ứng xử cố kết và ổn định của nền đường sẽ được tập trung để phân tích và đánh giá. Trường hợp nghiên cứu áp lực artesian pressure ở khu vực nền đường Yangsan sẽ được phân tích chi tiết. Kết quả phân tích số cho thấy rằng, áp lực artesian gây cản trở đáng kể đến quá trình cố kết và làm giảm sự ổn định của công trình đường trên nền đất yếu. Độ lún của nền đất yếu chịu áp lực artesian lớn hơn đáng kể so với trường hợp không xét artesian do ứng suất hữu hiệu ban đầu giảm đáng kể khi có áp lực artesian. Từ các kết quả đạt được, các tác giả đề nghị rằng cần xem xét sự hiện diện của áp lực artesian và mức độ ảnh hưởng của nó để dự báo lún, tốc độ cố kết và ổn định cho công trình đường trên nền đất yếu.

Nguyễn Sinh Sắc là một nhà trí thức lớn vào đầu thế kỷ XX, mong muốn của ông là được đem trí tuệ và tài năng của mình để đóng góp cho dân tộc. Trong bối cảnh, xã hội Việt Nam đang trăn trở tìm phương hướng để giải phóng dân tộc thì cụ phải từ bỏ quan trường, đi vào Nam sống ẩn dật để tìm con đường phù hợp nhất cho việc truyền bá tư tưởng yêu nước. Khác với nhiều trí thức cùng thời, Nguyễn Sinh Sắc đi lên từ lớp nông dân nghèo khổ, đã bền chí, phấn đấu khổ học quyết vươn tới đỉnh cao của tri thức. Khi đỗ đạt cao, Nguyễn Sinh Sắc không hề quay lưng với người nghèo khổ, ngược lại sống hòa mình, hết lòng yêu nước, thương dân, sống thanh cao, chịu đựng nhiều nỗi đau truân chuyên. Trên cơ sở đối sánh các nguồn tư liệu, tác giả mạnh dạn đưa thêm một số ý kiến về hoạt động truyền bá tư tưởng yêu nước, khát vọng giành lại độc lập tự chủ dân tộc cho các tầng lớp nhân dân ở một số địa phương thuộc vùng đất Nam Kỳ của Phó bảng Nguyễn Sinh Sắc (1862 -1929), trong khoảng thời gian từ năm 1911 đến  năm 1929. Tác giả hy vọng, kết quả đạt được từ bài viết sẽ góp phần vào việc tìm hiểu, nghiên cứu về cuộc đời, sự nghiệp của Phó bảng Nguyễn Sinh Sắc.
Possible Linkage Between Tropical Indian Ocean SST Anomalies and the Date of First and Last Tropical Cyclones Landfalling in the Chinese Mainland
Authors: Qun ZHOU , Li-xin WEI , Min LI
Published: March 2022

Bases on the NCEP / NCAR reanalysis products, HadISST dataset, and data of tropical cyclone (TC)landfalling in the Chinese mainland during 1960-2019, the possible impacts of Indian Ocean Dipole (IOD) mode andIndian Ocean basin (IOB) mode on the last-TC-landfall date (LLD) and first-TC-landfall date (FLD), respectively, areinvestigated in this study. The LLD is in significantly negative correlation with autumn IOD on the interannual time-scale and their association is independent of El Niño-Southern Oscillation (ENSO). The LLD tends to be earlier when theIOD is positive while becomes later when the IOD is negative. An anomalous lower-level anticyclone is located aroundthe Philippines during October-November, resulting from the change of Walker circulation over the tropical Indo-westPacific Ocean forced by sea surface temperature (SST) anomalies related to a positive IOD event. The Philippinesanticyclone anomaly suppresses TCs formation there and prevents TCs from landfalling in the Chinese mainland due tothe anomalous westerly steering flows over southeast China during October-November, agreeing well with the earlierLLD. However, the robust connection between spring IOB and FLD depends on ENSO episodes in preceding winter.There is an anticyclonic anomaly around the Philippines caused by the tropical SST anomalies through modulating theWalker circulation during May-June when the IOB is warming in the El Niño decaying phase. Correspondingly, the TCsgenesis is less frequent near the Philippines and the mid-level steering flows associated with the expanded westernPacific subtropical high are disadvantageous for TCs moving towards southeast China and making landfall during May-June, in accordance with the later FLD. By contrast, cooling IOB condition in spring of a La Niña decaying year andnegative IOD cases during autumn could produce a completely reversed atmospheric circulation response, leading to anearlier FLD and a later LLD over the Chinese mainland, respectively.
