A Characterization of the Circumstellar Gas of WD 1124−293 Using Cloudy
Authors: Steele Amy , Debes John , Xu 许偲 Siyi 艺 , Yeh Sherry , Dufour Patrick 
Published: April 2021

Abstract
Between 30% and 50% of white dwarfs (WDs) show heavy elements in their atmospheres. This pollution is thought to arise from the accretion of planetesimals perturbed by outer planet(s) to within the WD’s tidal disruption radius. A small fraction of these WDs show either emission or absorption from circumstellar (C-S) gas. The abundances of metals in the photospheres of WDs with C-S gas are mostly similar to the bulk composition of the Earth. The C-S component arises from gas produced through collisions and/or the sublimation of disintegrating planetesimals. High-resolution spectroscopic observations of WD 1124−293 reveal photospheric and C-S absorption of Ca in multiple transitions. Here, we present high signal-to-noise ratio spectra, an updated WD atmosphere analysis, and a self-consistent model of its C-S gas. We constrain the abundances of Ca, Mg, and Fe in the photosphere of WD 1124−293, and find agreement with the abundances of these three species in the C-S gas. We find the location of the C-S gas is ∼100 white dwarf radii, the C-S and photospheric compositions are thus far consistent, the gas is not isothermal, and the amount of C-S Ca has not changed in two decades. We also demonstrate how to use Cloudy to model C-S gas viewed in absorption around polluted WDs. Modeling the abundances of gas around polluted WDs with Cloudy provides a new method to measure the composition of exoplanetesimals and will allow a direct comparison to the composition of rocky bodies in the solar system.
Cyclopropenone (c-C3H2O) as a Tracer of the Nonequilibrium Chemistry Mediated by Galactic Cosmic Rays in Interstellar Ices

Published: April 2021

Abstract
While gas-phase astrochemical reaction networks nicely replicate the abundance of hydrogen-deficient organics like linear cyanopolyynes, pathways to complex organic molecules (COMs)—organic molecules with six or more atoms—have not been completely understood, with gas-phase models often significantly underestimating fractional abundances of the astronomically observed organics by orders of magnitude. Here, by exploiting cyclopropenone (c-C3H2O) as a tracer, laboratory experiments on the processing of an ice mixture of acetylene(C2H2) and carbon monoxide (CO) by energetic electrons coupled with astrochemical model simulations expose a previously poorly explored reaction class leading to COMs via galactic cosmic-ray-mediated nonequilibrium chemistry. These processes occur within interstellar ices at ultralow temperatures, but not through traditional radical–radical pathways on grain surfaces in the warm-up phase of the ices as hypothesized for the last decades, but more likely through barrierless excited state reactions during the irradiation.

Abstract
We present a 5 Å–100 μm spectral energy distribution (SED) of the ultracool dwarf star TRAPPIST-1, obtained as part of the Mega-MUSCLES Treasury Survey. The SED combines ultraviolet and blue-optical spectroscopy obtained with the Hubble Space Telescope, X-ray spectroscopy obtained with XMM-Newton, and models of the stellar photosphere, chromosphere, transition region, and corona. A new differential emission measure model of the unobserved extreme-ultraviolet spectrum is provided, improving on the Lyα–EUV relations often used to estimate the 100–911 Å flux from low-mass stars. We describe the observations and models used, as well as the recipe for combining them into an SED. We also provide a semiempirical, noise-free model of the stellar ultraviolet spectrum based on our observations for use in atmospheric modeling of the TRAPPIST-1 planets.
Ascodipteron sanmingensis sp. nov., a new bat fly (Hippoboscidae: streblid grade) from Fujian, China
Authors: Sun Haoran , Ding Liang , Yan Liping , Pape Thomas , Zhang Dong 
Published: April 2021

The bat fly genus Ascodipteron Adensamer, 1896 currently contains 15 species, all of which occur in tropical and subtropical areas of the Eastern Hemisphere. A new species of endoparasitic bat fly, Ascodipteron sanmingensis sp. nov., was collected from the Great Himalayan Leaf-nosed Bat, Hipposideros armiger (Hodgson, 1853), during ecological studies on bats in Fujian, China.
A new species, Ascodipteron sanmingensis sp. nov., is described, based on dealate neosomic females and is supported by molecular data from a 368 bp fragment of the cytochrome B (Cytb) gene. Habitus and diagnostic details, as well as the attachment sites on the host, are documented with photographs. A detailed comparison of the new species with related species is provided and the new species is accommodated in the most recent key to the world species of Ascodipteron.
En quête d’identité
Authors: Barillot Patrick 
Published: April 2021

Le sujet n’a de cesse de s’interroger sur son identité. À son « qui suis-je ? », la réponse de l’identité apportée par le signifiant ne tarit pas sa revendication identitaire. C’est que l’identité signifiante est de structure différentielle et n’indexe pas, de ce fait, la singularité de l’identité propre au parlêtre. Cependant le névrosé se tient à distance de ce qui le singularise, il réclame la différence mais refuse la singularité. La psychanalyse offre la possibilité, à celui qui en a le courage, de répondre durablement au questionnement identitaire en partant de son Sans-Nom de névrosé pour arriver à son identité de jouissance, celle qui lui est propre et fixée dans son inconscient.
Le trait : du Réel à l’identification
Authors: Gaye-Bareyt Hervé 
Published: April 2021

L’identification est consubstantielle à la perte, celle de l’objet aimé pour Freud, celle qui autorise l’incise du Réel par le signifiant pour Lacan et qu’il nomme trait unaire en référence à la deuxième identification de Freud. Comment cette question du trait se décline-t-elle dans les différentes structures ? Lacan nous invite à découvrir l’œuvre de Tœpffer inaugurale de la bande dessinée, avec ces « histoires en estampes » qui nous permettent d’articuler la question de la division du sujet avec celle de la quête de l’objet aimé, et d’apprécier comment le trait fera le nom de l’auteur. Un cas clinique suivi en hôpital de jour viendra montrer, en contrepoint, comment le principe de coupure est posé dans le Réel et quelle inventivité va procéder à en pacifier la jouissance.
La phobie interroge le père dans sa fonction
Authors: Puig Lina 
Published: April 2021

Du père au père réel : j’ai tenté de me frayer un chemin dans les textes de Freud et de Lacan. Puis du père réel au réel du père, avec la part incastrable – reste et témoignage de l’opération de la castration symbolique chez le père – j’ai essayé de repérer ce fil, dans les textes lacaniens de l’année 1975.
Le narcissisme du désir
Authors: Izcovich Luis 
Published: April 2021

Avec la promotion des objets de consommation, notre civilisation a mis en valeur, tout spécialement, la dimension du regard et ses incidences négatives. Le regard, qui est au premier plan de la convoitise liée à l’envie et participe de la jalousie, est différent du regard comme objet cause du désir. Pour dégager le regard comme cause du désir, notre proposition sera de distinguer le désir qui prend appui sur une identification et qui est au service du narcissisme, du désir inconscient qui nécessite un écart avec le narcissisme. C’est ce que le parcours d’une analyse démontre : l’émergence d’un désir qui ne serait pas lié au désir de l’Autre.
« La possibilité d’un troisième sexe »
Authors: Geneste Bruno 
Published: April 2021

Lacan a évoqué sur la fin de son enseignement « la possibilité d’un troisième sexe », brièvement et énigmatiquement, à l’appui d’une configuration nodale inédite, le nœud borroméen généralisé. Ce nœud, dont il sera ici explicité les caractéristiques, permet-il de répondre des mouvements « troisième sexe » déjà interrogés par Freud et de jeter une lumière nouvelle sur le « neutre », ou est-il moyen pour mettre à jour de nouvelles conséquences du nouage sinthomatique mis au point à partir du séminaire Le Sinthome ?
Quel choix du sexe ?
Authors: Touchon Fingermann Dominique 
Published: April 2021

Les névrosés ne sont pas « des victimes de la civilisation ou de l’hérédité mais des estropiés de la sexualité », écrivait Freud en 1898. L’anatomie, qui ne fait pas le destin mais fait la différence, la malédiction sur le sexe, le pourtous phallique, l’obstination acéphale de la pulsion, le hasard des rencontres bonnes ou mauvaise qui prennent le corps par surprise, l’heure de vérité de la rencontre avec l’autre sexe : peut-on vraiment parler de choix ? La clinique psychanalytique avec les adolescents en particulier, nous met à l’écoute des chemins hasardeux qui mènent à l’évidence du « pas de rapport » et à la solution singulière de chacun frayée avec ou malgré les « choix » multiples proposés par le siècle.
Effectiveness of Self-Instructional Packages in Staff Development Activities
Authors: Rufo Kathryn L 
Published: April 2021

ABSTRACT
Developing productive, cost-effective instruction for frustrating hospital orientation is examined. Ten self-instructional packages used in orientation were tested to determine if learning gained from self-instruction and from lectures and/or demonstrations were equal.
Detailed description of the interpretation of statistical data, differences in learning, and advantages and disadvantages are presented to encourage nurses to examine how research can affect practice.
Is Retrospective Chart Audit a Viable Base for Continuing Education?
Authors: Ottoson Judith M , Stearns Norman S 
Published: April 2021

ABSTRACT
Using retrospective chart audit (RCA) to identify educational needs, Patient Care Related Reading (PCRR), a hospital-based continuing education program for nurses was developed. The study determined that, used alone, RCA was an inadequate tool for developing continuing education. First, deficiencies in patient care identified through RCA were frequently attributed to administrative rather than educational factors. Second, the audit process itself was unreliable due to inaccurate and delayed documentation (procedures) as well as a narrow focus. Thus, educational needs identified solely through RCA were frequently outdated, limited in scope, and not always relevant to current educational program planning. To best reflect current nursing care practices as well as administrative and staff interests, the RCA should be combined with other approaches to identify educational needs.
Academic Advisement and the RN-to-BSN Student
Authors: Kearney Rose T 
Published: April 2021

ABSTRACT
Recognizing the advisement needs of registered nurse students pursuing a baccalaureate in nursing while managing employment, family, and academic obligations is important. The most useful academic advising functions identified were advice on requirements and registration with respondents indicating self-monitoring of their degree progress. Respondents represented characteristics of adult learners who preferred scheduled interviews for advisement with apparent themes of firmness and availability of the academic adviser and flexibility in requirements.
Answer Changing: A Meta-Analysis of the Prevalence and Patterns
Authors: Waddell Donna L , Blankenship Jane C 
Published: April 2021

ABSTRACT
In order to determine the prevalence and patterns of answer-changing behavior, a meta-analysis of 61 studies was conducted. The findings of the individual primary studies were supported, which increased confidence in the conclusion that most students will change answers and this behavior will likely improve test scores. Moreover, neither age, gender, academic ability, personality traits, beliefs about answer changing, nor item characteristics systematically influenced answer-changing behavior. Practitioners of continuing nursing education need to know the effect of answer changing on test scores so that they may appropriately advise nurses who are preparing for objective tests.
Basic Academic Preparation of Foreign-Educated Nurses: A Base for Developing Continuing Education Courses
Authors: Bohnen Mollyn V , Balantac Deanna D 
Published: April 2021

ABSTRACT
This international investigation was conducted to determine curricular factors that may explain the high failure rate on the Nurse Certification Licensure Examination for Registered Nurses (NCLEX-RN) of foreign-educated nurses (FENs) seeking licensure in the United States. The framework was the existence of basic knowledge as a starting point for adapting and modifying practices (Alfano, 1971).
Onsite visits were used to conduct a curricular review of basic academic preparation of FENs at 19 nursing programs in 10 selected countries. Curricular factors found common to all schools and country-specific elements may explain the academic difficulties of FENs relative to licensure and nursing practice. Delineated curricular elements discussed can serve as a base for developing continuing education courses for foreign-educated nurses.
Outcomes of Nurse (RN) Refresher Courses in a Midwestern City
Authors: Kalnins Irene , Phelps Sharon L , Glauber Walter 
Published: April 2021

ABSTRACT
Graduates of RN refresher courses offered by three hospitals in a midwestern city from 1981 to 1991 were surveyed (N = 179) to compare the nurses who returned to work (n = 148, 82.7%) with those who did not return to work (n = 26, 14.5%) on demographic and career characteristics, personal responsibilities, and attitudes toward professional nursing (5 nurses [2.8%] did not respond to this item). The non-returning group had fewer mean years of experience prior to leaving nursing, more mean years since last nursing position, and lower mean scores on the Professional Attitude scale used in this study, but the differences were not statistically significant.
Reliability and Validity of Critical Care Orientation Tests
Authors: Recker Diane , O'Brien Colleen 
Published: April 2021

ABSTRACT
The purpose of this study was to establish the reliability and validity of the multiple choice orientation tests used in one critical care unit. A criterion-referenced measurement framework was used to develop 10 orientation tests covering five content areas, two tests for each content area. A sample of 40 critical care nurses (CCNS) and 31 medical-surgical nurses completed the tests. Standard reliability and validity measures were performed including: test-retest, parallel forms, construct and decision validity and item analysis. Parallel form correlations ranged from .46 to .90 (P<.05). Test-retest correlations ranged from .56 to .93 (P<.01). A significant (P<.01) difference was found between the scores of the critical care nurses and medical-surgical nurses for nine of the tests. Reliability and validity were supported for the tests. This study identifies one process that can be used in test development.
Gaming: A Technique That Adds Spice to Learning?
Authors: Kuhn Merrily A 
Published: April 2021

ABSTRACT
Gaming, as a teaching strategy, offers a unique method of reinforcing facts and allows for acquisition of knowledge and process skills. Gaming facilitates problem solving, and sometimes critical thinking, and can monitor results of the learners' actions. Gaming also allows students to challenge the thinking and hypotheses of others. This article, designed for all nurse educators, reviews the advantages and disadvantages of certain gaming techniques. These ideas are obtained from surveying the literature for game ideas that have been developed over the last 15 years.
Preparing Nurses for the Challenge of the New Focus on Community Mental Health Nursing
Authors: Bunn Helen 
Published: April 2021

ABSTRACT
Canada has endorsed the concept of primary health care and the need to increase community-based mental health care. Mental health nurses in Canada have been reluctant to adopt a primary health care model. Canadian nursing education programs, to this point, have not prepared nurses adequately for this change. In response to these issues, a Community Mental Health Nursing course, based on Canadian health care principles, was developed and implemented for practicing registered nurses enrolled in the BScN program (Post-RN) at the University of Ottawa, Canada. Feedback elicited from students and clinical preceptors has been positive.
Characteristics and Outcomes of a Statewide Nurse Refresher Project
Authors: Bellack Janis P 
Published: April 2021

ABSTRACT
This article describes a 3-year, federally funded statewide nurse refresher course offered by the South Carolina Area Health Education Consortium (S.C. AHEC) to address the state's nursing shortage. A total of 222 inactive RNs enrolled in the 160-hour course during the project period. A follow-up survey of the first 160 graduates of the course revealed that 76% had returned to active nursing practice, the majority in hospital staff nurse positions. Forty percent of respondents returned to work full-time, the remainder part-time. Respondents were employed in 72 health care facilities in 36 different communities in the state. Nearly 25% reported working in rural, underserved areas designated as health professions shortage areas. A survey of employers of course graduates revealed a high degree of satisfaction with their performance. As health care reform takes shape and nursing roles shift, the nurse refresher course will be revised and updated to assure its continued relevance for current and future practice.
Reconsidering Rituals: A Vehicle for Educational Change
Authors: DeLuca Ellen Kathleen 
Published: April 2021

ABSTRACT
Rituals continue to be a component of nursing practice. Their origins may be related to the historical antecedents of physician domination, the experience of sacred events such as birth and death, and an unconscious need of nurses not purely explained by logic. Educators will be most able to promote changes in practice by incorporating the meaning of ritual in educational programs through discussing issues and interacting with nurses on an individual basis as they master new practice techniques. It is essential that educators become one with the environments of nurses so an understanding of context and values can impact educational strategy and reform nursing practice.
Pain Assessment and Management in Surgical Cancer Patients: Pilot and Evaluation of a Continuing Education Program
Authors: Francke Anneke L , Abu-Saad Huda Huijer , Grypdonck Mieke 
Published: April 2021

ABSTRACT
In a pilot study, a continuing education program on pain assessment and management was implemented and evaluated. Questionnaires were completed by the nurse participants at the beginning, the end, and 2 months after the end of the pilot program. After the pilot program, participants reported having engaged in qualitatively improved psychosocial pain-reducing interventions. Findings from the pilot study were used to develop a definitive program and questionnaires of a larger intervention study. This article illustrates the usefulness of initially conducting research on a small-scale basis.
From Outside the Walls: A Qualitative Study of Nurses Who Recently Changed From Hospital-Based Practice to Home Health Care Nursing
Authors: Murray Teri A 
Published: April 2021

ABSTRACT
Acute care facilities are no longer viewed as the center of the health care network. Efforts to reduce hospital length of stay will continue to spur the growth of care delivered in homes. With the downsizing of many hospitals, the need for nurses in acute care settings will decline. Many acute care nurses are finding themselves seeking employment opportunities in home health care settings. The purpose of this study was to examine nurses' experiences when they change from hospital-based practice to home health care nursing. The qualitative mode of inquiry was used to conduct taped-recorded interviews of 25 baccalaureate-prepared nurses in a large metropolitan area. Stressors experienced by the nurses were identified as well as adaptations required to minimize role stress. Continuing education programs can provide information and skills needed to improve nurses' competencies to function in a health care system projected to be more community-based, which includes home health care.
Evaluation of an HIV/AIDS Continuing Education Program
Authors: Sowell Richard , Seals Greg , Wilson Barbara , Robinson Carole 
Published: April 2021

ABSTRACT
An HIV/AIDS education model was implemented for rural nurses as a demonstration project in Georgia. The overall goal of the project was to increase the quality of and access to HIV/AIDS-specific services in rural communities. Public health and community nurses were the focus of this effort due to their current roles in providing health care to rural and underserved populations and their potential for networking across health care and social services agencies to form an HIV/AIDS response network.
One hundred and seventy-five nurses completed the program. Program evaluations revealed that, after completing the HIV/AIDS course, participants' professional preparedness, attitudes toward people with HIV/AIDS, and knowledge had improved. Consistently, participants' scores in each of these areas increased from the pretest to the posttest. Additionally, nurses participating in the program reported in a follow-up survey that they felt better prepared to care for people with HIV/AIDS. While there is a need for further HIV/AIDS education in rural communities, results of the program support its potential use as a model for other rural communities.
Teaching Community Health Nursing by Distance Methods: Development, Process, and Evaluation
Authors: Blakeley Judith A , Curran-Smith Janet 
Published: April 2021

ABSTRACT
In 1995, 23 post-RN (RN-to-BSN) students successfully completed the first clinical nursing course offered by distance methods at Memorial University of Newfoundland. Distance delivery improved access to the course for RNs dealing with conflicting work and family demands. Students rated the course favorably overall and found they had learned and applied new knowledge and skills. Community health nurses, who acted as field guides, and their supervisors were satisfied with their roles and responsibilities. However, one need identified was for detailed information about the course, and another was for more frequent communication with the course instructors during the term. Evaluation found students were able to meet their course objectives and perform as well as students who had completed a similar on-campus course.
Accreditation of Continuing Education: The Critical Elements
Authors: DeSilets Lynore D 
Published: April 2021

ABSTRACT
Accreditation in nursing continuing education (CNE) is central to professional values such as accountability, competence, and knowledgeable practice. Organizations choosing to participate in the accreditation/approval system make a commitment to quality. This article reviews the history of accreditation, defines the language, describes the system and process, and discusses agency/institution characteristics that should be in place before beginning an accreditation application process. The American Nurses Credentialing Center Commission on Accreditation model is used as the prototype.
