Authors:   MIDDLE EAST TECHNICAL UNIVERSITY DEPARTMENT OF MATHEMATICS 06531 ANKARA, TURKEY E-mail address: marat@metu.edu.tr, AKHMET MARAT , KIVILCIM AYSEGUL
Published: April 2021

This paper examines impulsive non-autonomous periodic systems whose surfaces of discontinuity and impact functions are not depending on the time variable. The W−map which alters the system with variable moments of impulses to that with fixed moments and facilitates the investigations, is presented. A particular linearizion system with two compartments is utilized to analyze stability of a grazing periodic solution. A significant way to keep down a singularity in linearizion is demonstrated. A concise review on sufficient conditions for the linearizion and stability is presented. An example is given to actualize the theoretical results.

Зв'язок STEM-освіти з бізнес-школами в США як перспективний засіб модернізації освіти
Authors: Prymak O.
Published: April 2021

В статті обґрунтовано ідею, що STEM-освіта популяризується урядом з кожним роком дедалі більше через прийняття певних концепцій та стратегічних планів на майбутнє як в Україні, так і за кордоном. Проте STEM, як певний тип інтегрованих навчальних програм в США, було започатковано та активно підтримується не лише державними, а й бізнесовими структурами з метою розвитку країни та підприємницької діяльності. Проаналізовано та визначено досвід взаємодії бізнес-структур та закладів освіти США через залучення та пропагування освітніх програм STEM. Висвітлено, що це стосується не тільки ІТ-спеціалістів у високотехнологічних галузях, а й загалом економічно-активного населення, адже інноваційні технології стимулюють розвиток інформаційного суспільства. Особливу увагу приділено інтеграції бізнес-шкіл та студентів STEM-спеціальностей, як перспективному засобу модернізації освіти в Україні. Виділено й описано програми, що які підтримуються та заохочують активну молодь до здобуття інноваційної освіти, в тому числі й у бізнес-структурах. Простежено, що одним із найважливіших аспектів STEM-навчання є формування конкурентноспроможного фахівця у будь-якій галузі, здатного мислити критично, абстрактно й алгоритмічно. Визначено, що оновлені STEM-програми спрямовані на формування компетентностей, які є найбільш актуальними на ринку праці. Підкреслено актуальність питання інтегрованої освіти, що й досі залишається недостатньо дослідженим у нашій країні, тому українські вчені намагаються перейняти американський досвід упровадження інновацій в освіті. Виокремлено особливості інтегрованого навчання, в якому американські вчені вбачають майбутнє освіти та інноваційного бізнесу загалом. Зазначено, що зарубіжний досвід популяризації STEM може бути основою для проектування програм упровадження технологій інноваційного навчання в Україні, так як загальновідомо, що питання STEM-навчання залишаються недостатньо дослідженими в нашій країні.
Модель та алгоритми гранулярної фільтрації у задачі глобальної локалізації мобільного робота
Authors: Pantyeyev R. , Bidyuk P.
Published: April 2021

Методи оцінювання параметрів і станів динамічних систем – актуальна задача, результати розв’язання якої знаходять своє застосування у різних галузях діяльності, включаючи дослідження процесів у технічних системах, космологічних та фізичних дослідженнях, медичних діагностичних системах, економіці, фінансах, біотехнологіях, екології та інших. Незважаючи на значні наукові і практичні досягнення у цьому напрямі, дослідники багатьох країн світу продовжують пошуки нових методів оцінювання параметрів і станів досліджуваних об’єктів та удосконалення існуючих. Прикладом таких методів є цифрова та оптимальна фільтрація, які знайшли широке застосування у технічних  системах ще у середині минулого століття, зокрема, у обробці фінансово-економічних даних, фізичних експериментах та інших інформаційних технологіях самого різного призначення.
Розглядається модель та алгоритми гранулярної фільтрації на практичному прикладі – варіанті задачі глобальної локалізації мобільного робота (global localization for mobile robots) або задачі про викраденого робота (hijacked robot problem). В загальному варіанті вона полягає у визначенні положення робота за даними з сенсора. Ця задача була в цілому розв’язана рядом імовірнісних методів в кінці 90-х-початку 2000-х років. Задача є важливою і знаходить застосування у мобільній робототехніці та промисловості. Схожими за суттю є задачі позиціонування підводних човнів, літальних апаратів, автомобілів тощо. Також розглядається задача позиціонування робота. Нехай у темному лабіринті увімкнувся робот. Він має карту лабіринту та компас. У лабіринті в деяких точках встановлені позначені на карті станції, які можуть приймати і відбивати сигнал. Робот не знає, в якому місці лабіринту він знаходиться, але він може в кожний момент часу відправляти сигнал і з деякою похибкою дізнаватись відстань до найближчої до нього станції. Робот починає блукати лабіринтом, роблячи кожний крок у новому випадково обраному напрямку, але його компас також дає деяку несистематичну похибку. На кожному кроці робот визначає відстань до найближчої станції. Мета – з’ясувати координати робота у лабіринті в системі відліку, введеній на карті.
E-commerce and M-commerce as Global Trends of International Trade Caused by the Covid-19 Pandemic
Authors: Dumanska Ilona , Hrytsyna Lesya , Kharun Olena , Matviiets Olha
Published: April 2021

The article examines the impact of the COVID-19 pandemic on international trade and identifies e-commerce and m-commerce as its global trends. A scientific and methodological approach to the study of the vector and specifics of the development of e-commerce and m-commerce is formed given the lack of necessary statistical information to assess the state of e-commerce in a country and linguistic features of definitions. The influence of e-commerce and m-commerce on the online shopping and sales industry has been established. The global distribution of Internet sources used by consumers, global sales in m-commerce as a percentage of e-commerce and the impact of the coronavirus pandemic on online traffic and changes in transactions by industry are analyzed. The transition of e-commerce to m-commerce was revealed as a result of the increase in the share of mobile transactions in view of the development of markets in countries focused primarily on mobile devices and their active use. As a result of the post-pandemic forecast in the trends of international trade and e-business priorities, a promising increase in world sales in e-commerce has been established. The main trends of further development of e-commerce and m-commerce in the field of international trade are identified, such as: big data, personalization, e-mail marketing, transition of e-commerce to e-commerce, ordering services online and transition of retail to online, electronic public procurement, omnichannel and multichannel, socially oriented commerce, improved work with the community and the need for efficient logistics
Exemplars can Reciprocate Principal Components
Authors: Greer Kieran
Published: April 2021

This paper presents a clustering algorithm that is an extension of the Category Trees algorithm. Category Trees is a clustering method that creates tree structures that branch on category type and not feature. The development in this paper is to consider a secondary order of clustering that is not the category to which the data row belongs, but the tree, representing a single classifier, that it is eventually clustered with. Each tree branches to store subsets of other categories, but the rows in those subsets may also be related. This paper is therefore concerned with looking at that second level of clustering between the category subsets, to try to determine if there is any consistency over it. It is argued that Principal Components may be a related and reciprocal type of structure, and there is an even bigger question about the relation between exemplars and principal components, in general. The theory is demonstrated using the Portugal Forest Fires dataset as a case study. The Category Trees are then combined with other Self-Organising algorithms from the author and it is suggested that they all belong to the same family type, which is an Entropy-style of classifier. Some analysis of classifier types is also presented.

Arab Official Efforts to Raise Awareness of COVID-19: The Crisis and Emergency Risk Communication Model in the UAE
Authors: Aissani Rahima
Published: April 2021

This study aims to identify the contents of crisis communication used by the government of the United Arab Emirates (UAE) to raise awareness of the dangers of coronavirus (COVID-19) and reduce its spread in three phases – preparation, initial and maintenance – following the Crisis and Emergency Risk Communication model. The study implemented content analysis for three elements from the crisis and risk communication components introduced by the UAE government. At the start of the coronavirus pandemic crisis, the UAE government quickly drew up a national plan to deal with the crisis under the leadership of the National Emergency Crisis and Disaster Management Authority (NCEMA) and the Ministry of Health and Prevention (MOHAP). In the maintenance phase, it relied on a number of means to raise awareness of coronavirus and prevent its spread; these included press conferences, periodic media briefings, awareness campaigns, community-based initiatives, and electronic publications on official websites of the NCEMA and the MOHAP. It also provided diverse, honest, accurate and detailed crisis communication to explain the crisis. All the UAE government's communication content provided a variety of rich information on the new coronavirus. This helped to deal with the crisis efficiently and effectively and contributed to raising community awareness and highlighting the health system's ability to investigate and follow up in a timely manner.

Authors: Shahzad Hamza , Jabeen Hira , Arslan Hafiz Rana Muhammad , Ghouri Muhammad Hashim , Gondal Subhan Ali , Umar Muhammad , Arif Muhammad , Bibi Saima
Published: April 2021

Background: People nowadays have developed a new passion of weightlifting. Weightlifting focuses on vigorous muscle development. But injuries are also common in weightlifting. This study aims to compare the injury rates among supervised and non-supervised weightlifters.
Methods: A group of 138 weight lifters was divided into two groups i.e. who did training under supervision and the other who did training without any supervision. Injuries related to musculoskeletal system were identified using Nordic musculoskeletal questionnaire. Data was analyzed using SPSS. Chi square test was used to see the association of musculoskeletal pain among weightlifters with or without supervision.
Results: Significant association found between musculoskeletal injuries and supervision. Injuries lesser in number among supervised weightlifters as compared to unsupervised weightlifters. Mean age of weight lifters under supervision and without supervision was 21.99 (SD 3.81) and 24.64 (SD 5.01) respectively. Mean workout days /week among weight lifters under supervision was almost same i.e. 5.67 (SD .63) and was 5.62 (SD .81). Out of 51 participants who work-out for 46-60 min, 30 were not under supervision while 31 weightlifters who work-out for 61-90 min were working out under supervision. Injury rate was more in the region of shoulder in both groups supervised and unsupervised groups while hip/thigh region was less involved in both supervised and unsupervised groups.
Conclusion: Overall results showed significant association between musculoskeletal injuries and supervision. Injury rate was more among weightlifters who work without supervision as compared to those who work under supervision. Care should be taken and weight lifting and exercises must be performed under expert’s supervision.
Decent work for the digital platform workers. A preliminary survey in Beijing
Authors: Xu Y. , Liu D.
Published: April 2021

This paper discusses the status and implications of the employment relations and working conditions experienced by digital platform workers; the analysis is based on a survey conducted in 2017 on 1 338 workers engaged in work-on-demand via apps (WODVA) from 25 platforms in Beijing, of whom 48.8 % are full-time WODVA workers or take WODVA as their primary job. The survey ﬁnds that nearly a half of the respondents engage in platform work due to a lack of employment opportunities in formal labor markets or their permanent jobs providing insufﬁcient income. The respondents reveal substantial decent work deﬁcits in representation, compensation, job stability, social protection, working time, and health and safety: 1) WODVA workers seldom have any voice in labor dispute settlements and have a very low rate of unionization; 2) about one third of the full-time WODVA workers cannot earn a living wage and 7.6 % of them earn less than the minimum wage level; 3) three quarters of the full-time WODVA workers have no labor contract with the platforms or other employers, nor access to employer-contributed social insurances; 4) overtime work and underemployment coexist among full-time respondents, with nearly 10 % working for fewer than 4 hours per day while nearly 10 % work for more than 11 hours per day; 5) a majority of respondents run a higher risk of occupational health or physical risks, without any protection provided by the platforms or employers. To promote decent work by digital platform workers, the State needs to establish a portable social security system extending to all workers, to facilitate association and collective actions of platform workers either by extending the outreach of traditional unions or fostering new forms of organizations, to leverage digital technology to facilitate platform workers’ organization and information sharing, and even to promote universal basic income and a workers’ cooperative of platforms in the long run.
Digital law: The pursuit of certainty
Authors: Inozemtsev M I.
Published: April 2021

The article deals with the development o digital law as an instrument for regulating the digital economy. It is proved that, within the academic environment, the concept of “Internet law” is still more well-established than the concept of “digital law”. It is in this manner that the legal sphere responds to the challenges of the digital revolution and reflects the digital economy. The debate as to whether “Internet law” can be considered either as a separate branch of law or as a branch of legislation has not yet subsided. Nevertheless, “Internet law” is undoubtedly an independent academic discipline, textbooks on which are published in Russia. However, Russia needs to develop a digital economy; this is why the national project “Digital Economy of the Russian Federation” was adopted in 2018, regulatory support for which forms the basis of digital law in Russia. At the same time, the extensive experience of digital economy regulation in both its neighbouring countries and beyond is taken into account. Especially attractive is the national strategic model, which assumes the most rapid procedure for adopting changes and consequently adapting digital legislation, is aimed at the long-term perspective, and lets popular opinion — as well as the opinions of public organizations, the business community, and government representatives — be taken into account. In addition to foreign experience in regulating the digital economy, we should also use the best practices of domestic and foreign legal science.

Authors: Pautasso Diego , Nogara Tiago Soares , Ungaretti Carlos Renato , Doria Gaio
Published: April 2021

Este artigo visa discutir o papel da extensão da Nova Rota da Seda – ou Iniciativa do Cinturão e Rota (Belt and Road Initiative – BRI) – para a América Latina em um quadro de transição sistêmica. Argumentamos que, diante das dificuldades de articulação de soluções locais para os dilemas regionais, a oportunidade de adensamento das relações e da cooperação com a China tende a suprir lacunas necessárias para fazer avançar projetos de desenvolvimento dos países da região. Após a introdução, na segunda seção, trataremos do processo de ascensão internacional da China, reconhecendo a Nova Rota da Seda como vetor fundamental de sua projeção global. Na terceira seção, abordaremos o panorama de crescente sinergia entre os países da América Latina e a China, bem como as possibilidades esboçadas pela possível implementação da Nova Rota da Seda na região. Por fim, na quarta seção, discutiremos os dilemas latino-americanos nesse complexo quadro de transição sistêmica, abordando as conexões entre o recrudescimento da rivalidade sino-estadunidense e as questões pertinentes aos mecanismos de cooperação bilateral e multilateral hemisféricos.
A Ascensão chinesa, as transformações da economia-mundo capitalista e os impactos sobre os padrões de comércio na América Latina
Authors: Barbosa Alexandre de Freitas
Published: April 2021

Este artigo realiza uma discussão em torno do conceito de economia-mundo capitalista, procurando mostrar o seu potencial analítico para explicar o processo de transformação no funcionamento da economia global antes e depois da crise de 2008. Com base nesse aparato teórico são apresentados os diversos padrões de comércio estabelecidos entre a China e algumas regiões centrais e periféricas entre os anos 2000 e 2016, com o objetivo de apontar especialmente como isso impacta os países latino-americanos. A ascensão chinesa e os vários modelos de inserção externa desses países têm provocado um processo de desintegração e fragmentação da América Latina, sobretudo em termos econômicos, trazendo novos dilemas para o desenvolvimento da região.
Earthworm species in Musa spp. plantations in Brazil and worldwide
Authors: Cremonesi Marcus Vinicius , Santos Alessandra , Rozane Danilo Eduardo , Carolina Bartz Marie Luise , Brown George Gardner
Published: April 2021

Bananas and plantains are major commodity/food crops that represent an important habitat for earthworms, although so far, no review is available on earthworm communities associated with banana/plantain crops worldwide. The Vale do Ribeira region is among the largest banana producing areas in Brazil, but little is known of the earthworms living there. Hence, the present study assessed earthworm populations and species in three banana plantations and adjacent Atlantic forest fragments along the Ribeira de Iguape River using standard (hand sorting) methodologies. Furthermore, we review earthworm populations reported in banana/plantain plantations worldwide. Only two species (Pontoscolex corethrurus,Amynthas gracilis) belonging to two families (Rhinodrilidae, Megascolecidae) were found in the Ribeira River valley, occurring concurrently. Abundance was low (< 13 indiv. m-2) compared with other banana plantations worldwide, that frequently surpassed 100 indiv. m-2. More than 70 studies reported earthworms from >200 banana plantations in 28 countries, and mean species richness was 2.7 per site, ranging from 1 to 10 species. Exotics predominated in most sites andP. corethruruswas the most prevalent species encountered. Overall, more than 104 species from 10 families were reported, with around 61 native and 43 exotic widespread species, mainly of the Megascolecidae, Lumbricidae and Acanthodrilidae families. Richness was highest in India (27 spp.) and the Canary Islands (25 spp.), but native species dominated only in a few countries and sites, while exotics were prevalent especially in island countries and Brazil. Lower-input practices appear to be important for earthworm communities and banana plantations can have large earthworm populations in some cases, which may be contributing to soil processes and plant production, topics that deserve further attention. However, many important banana-producing countries have not yet been evaluated, so further work is warranted, both in terms of applied ecology and biodiversity.

L'éthique en contexte info-communicationnel numérique
Authors: Cansell Patrick , Desmoulins Lucile
Published: April 2021

« Esthétique du dedans », l’éthique est pourtant très valorisée dans les promesses et les relations commerciales. Subjective et personnelle, elle reste éminemment contextuelle car liée à la qualité de la relation entre un prestataire et un client (proximité, confiance, antériorité, affinité) et la diversité des situations de travail. Ce chapitre interroge les régimes de vérité au sens foucaldien et de sincérité auxquels se référent les prestataires de services en IE et qui sont à la fois invoqués et sémiotisés dans les documents fournis aux clients. Il questionne aussi les conditions de la confiance dans le cadre de relations hiérarchiques ou commerciales.
Pallier le manque de ressources dans une organisation liquide : le cas du service de neurologie d’un hôpital public
Authors: Rossano Maryline , Abord de Chatillon Emmanuel
Published: April 2021

L’hôpital va mal, comme en témoignent la recherche sur le sujet et les médias. Les personnels soignants dont les indicateurs de santé au travail se dégradent (Abord de Chatillon et al., 2017) parviennent malgré tout à trouver des solutions et «  sortir la production  » (de Terssac, 1992). Il parait donc important de saisir comment, malgré les contraintes qu’ils subissent, les personnels soignants réussissent à mobiliser des ressources suffisantes pour construire un travail de qualité. Pour comprendre comment les acteurs mobilisent ces ressources, 90 heures d’observation auprès des personnels (aides-soignants, infirmières, cadre de santé) d’un service de neurologie ont été réalisées ainsi que dix entretiens semi-directifs. L’enjeu de cette proposition est donc de mettre en lumière comment les individus dans un univers liquide prennent en main leur santé au travail en transformant des éléments de leur quotidien en ressources. La théorie de la conservation des ressources (Hobfoll, 1989, 1998) est mobilisée comme cadre théorique. Les résultats confirment d’une part le caractère liquide de l’organisation hospitalière et d’autre part mettent en lumière la capacité de résilience des individus lorsqu’ils construisent des ressources dans un environnement contraint prenant ainsi en main leur santé au travail.
La politique de défense de la Pologne dans le contexte du Brexit : Bilatérale, multilatérale ou flexilatérale ?
Authors: Zima Amélie
Published: April 2021

Cet article analyse les conséquences du Brexit sur la politique de défense des États membres de l’UE. Il prend comme exemple la Pologne. Premièrement, il présente les raisons de la défiance initiale des gouvernements polonais vis-à-vis des compétences de l’UE en matière de défense. Ensuite, l’article examine les raisons ayant conduit à la signature du traité bilatéral de défense avec le Royaume-Uni ainsi que son impact pour la coopération de défense au sein de l’UE et de l’OTAN. Enfin, il montre que la politique de sécurité de la Pologne témoigne moins d’un biais pro-atlantiste et d’une défiance envers le multilatéralisme que d’une approche flexilatérale où le Brexit n’a qu’un rôle limité.

Toutes les appellations autour du patient expert telles que patient-intervenant, patient-partenaire, patient-tuteur, patient-ressource, patient-enseignant… créent un flou qui nuit à la compréhension de sa place et de son rôle. Une psychologue clinicienne, une patiente experte et un cadre administratif, à l’origine de la création d’un dispositif de patients experts dans le parcours de soin du service d’addictologie de l’hôpital Bichat, donnent quelques points clés issus de leur expérience afin de permettre à chacun d’entamer ou de poursuivre une réflexion personnelle et institutionnelle.
Le parcours de rétablissement des usagers de drogues illicites : ce que révèlent les journaux de santé des personnes concernées
Authors: Greacen Tim , Simon Antoine , Jouet Emmanuelle
Published: April 2021

Au-delà de leur problème par rapport à l’addiction elle-même, les usagers de drogues illicites se trouvent souvent confrontés à des problèmes multiples d’abord d’ordre médical et psychologique, mais aussi relatifs à leur inscription dans la vie sociale en général. Si un nombre important d’études se sont focalisées sur la gestion des produits et des enjeux psychologiques qui les entourent, il existe peu de recherches s’adressant spécifiquement à la question de l’environnement social et de son impact sur le parcours de rétablissement des personnes. Dans le cadre de l’étude DURESS ( Drug Use Recovery, Environment and Social Subjectivity ), 25 usagers de drogues illicites suivis dans un centre parisien ont tenu des journaux de santé sur leur vie de tous les jours et les obstacles et facilitateurs rencontrés au cours de leurs parcours de rétablissement. Les questions de la vie familiale, de la vie sociale, du logement, de l’emploi et des contraintes administratives et juridiques y jouent un rôle majeur.

Teaching Staff to Cope with Patient Violence
Authors: Fein Beverly Ann , Gareri Elaine , Hansen Paul
Published: April 2021

In all areas of nursing practice from medicine fo psychiatry, circumstances may occur that precipitate patient violence. Injury to staff and patients and damage to property are possible outcomes when violence occurs. Fears of further danger may increase the anxiety level of the staff, leading to demoralization and decreased staff effectiveness. These problems are exacerbated when staff are unprepared and unable to cope with assault from patients. Resources and materials for teaching staff to cope and manage patient violence are absent in the nursing literature. This report describes an inservice course being taught by the authors on "the Management of Assaultive Behavior." The course includes eight units covering all aspects of management: a model of the assault cycle, anxiety awareness, patterns that predict assault, assaultive crises, physical interventions, restraints, seclusion, and assault reporting procedures. The couse format, its mode of presentation, and beginning evaluation results are presented.

Enhancing Quality Critical Care Education: Establishing a Consortium
Authors: Earp Jaibun K , Capka Mary B , Davis Alice E , McLain Rhonda M , Ney Cynthia A , Moorhead Joel
Published: April 2021

ABSTRACT

The demand for expanded knowledge and accountability in critical care nursing has increased the need for qualified critical care nurses and is tempered by requirements that their preparation be cost-effective. The Emory University School of Nursing (EUSN) has pioneered in meeting this challenge. Since June 1988, a Critical Care Consortium consisting of the EUSN and Emory-affiliated hospitals has been operational, providing uniform critical care education to multiple hospital nursing staffs. Instructional resources are being economically utilized, eliminating duplication of efforts. This collaboration between academic and service settings enhances productivity, quality patient care, professional growth, and promotes significantly greater interinstitutional cohesiveness.
Evaluation of a Critical Care Nursing Internship Program
Authors: Hartshorn Jeanette C
Published: April 2021

ABSTRACT

Many hospitals have developed internship programs to assist in the movement of new graduates into the critical care unit. The purpose of this study was to evaluate an existing critical care nurse internship program. Five research questions were developed to guide the evaluation process. Results suggest that the goals of the program were met. Specific weaknesses in preparation of preceptors and knowledge base of interns were identified. High burnout scores were also identified, suggesting that new graduates may find the experience of working in critical care very stressful. Implications for revisions of the existing program and for others involved in similar programs are discussed.
Reading Activities of Staff Nurses From States With Mandatory or Voluntary Continuing Education
Authors: Gessner Barbara A , Armstrong Myrna L
Published: April 2021

ABSTRACT

Reading activities of staff nurses (N = 269) residing in six states with mandated educational requirements for relicensure were compared with a similar number (N = 275) of staff nurses from states that have no legislative continuing education (CE) requirements. Time spent reading both professional and general literature was obtained. Nurses spent twice as much time reading general literature as professional literature. Both groups stated that conferences were the preferred method of CE; reading was the second choice in mandatory states and the third in voluntary states. However, nurses in voluntary states spent slightly more time reading professional literature.

Enjoyable Learning Experiences-An Aid to Retention?
Authors: Leidy Karen
Published: April 2021

ABSTRACT

Stress is related to job dissatisfaction and is a significant factor in high turnover rates for nursing staff. In the current labor market, all possible aids to retention need to be considered and innovative approaches need to be tried. Perhaps one of the most powerful retention tools, laughter, is being overlooked.

Research indicates that laughter and humor have positive effects by reducing stress and enhancing the immune system. Stress within the hospital environment contributes to burnout. Burnout results in absenteeism, decreased productivity, and turnover. Incorporating laughter and humor into educational programs is one strategy to reduce stress and may be an antidote for burnout.

A game called "Not So Trivial . . . Protective Pursuit" was used with 150 staff on the evening and night shift. The observed effects were very positive. The implications are that nurse educators can make a significant contribution to preventing hospital burnout by making learning experiences enjoyable.
Organizational Models and Staff Preparation: A Survey of Staff Development Departments
Authors: Blocker Virginia T
Published: April 2021

ABSTRACT

A national survey of staff development (SD) departments of hospitals was conducted to determine the organizational models (centralized, decentralized, or combination) used. The survey asked about departmental organization, instructor role, staff title, core responsibilities, percentage of work for various departments, SD department head and staff educational preparation, and demographic data. This article discusses the data obtained from the 48 responses (41%) that pertain to the organizational model (26 or 54% used combination model) and staff preparation (master's degree was most prevalent). The data and survey approach could be used by a SD department when choosing an organizational model.

Authors: Finnick Mary , Crosby Frances , Ventura Marlene R
Published: April 2021

ABSTRACT

An increasing demand is being placed on nurses who are practicing in long-term care settings to conduct and/or participate in quality assessment and improvement (QAI) activities. A local survey of directors of nursing in long-term care indicated both personal interest and interest on the part of their staff nurses to attend continuing education (CE) programs regarding quality of care to increase their competencies in this area. Specific interest areas and recommendations for an educational offering regarding quality assessment and improvement for long-term care nurses are described.
Informational Needs and Preferred Time to Receive Information for Phase II Cardiac Rehabilitation Patients: What CE Instructors Need to Know
Authors: Hanisch Patti
Published: April 2021

ABSTRACT

The purpose of this study was to determine the perceived importance of selected informational needs of cardiac rehabilitation patients and to determine the best time interval to provide this information. The findings of this study support previous studies showing that cardiac rehabilitation patients perceive all information as important and, as such, it is essential that patients and families receive daily information. Information should be provided simply and in nontechnical terms. With a trend toward shorter hospital stays, this study challenges the health care team to provide necessary information in less time. Implications for staff development are described.
Preparing for Mandatory Continuing Education-Assessing Interests
Authors: Cannon Christine A , Waters Linda D
Published: April 2021

ABSTRACT

Assessment of needs is the foundation of nursing practice as well as nursing education. To increase responsivity to the continuing education (CE) needs of registered nurses (RNs) within a small, yet diverse, mid-Atlantic state in which CE was recently mandated for relicensure, a telephone survey was used to gather information on a large nonrandomized sample of RNs. Preferences for types of programming, methods and locations for acquiring CE, scheduling, academic credit in addition to CE credit, and an automated service for maintaining CE attendance records were identified. This study presents an overview of survey results helpful in planning offerings most likely to attract and satisfy nurses.

DISTRACTION PINNING FOR RADIAL METAPHYSIS FRACTURES
Authors: Dabezies Eugene J , Chuinard Robert G , Kitziger Raymond F
Published: April 2021

ABSTRACT: Comminuted fractures of the distal radial metaphysis are inherently unstable. Reduction can be obtained utilizing traction, and then the fracture stabilized by placing pins proximal and distal to the fracture and incorporating these pins in a short -arm cast. The results of 36 patients treated in this manner were analyzed. An excellent result was achieved in 78% of the cases.
LEG LENGTH DISCREPANCY: HOW MUCH IS TOO MUCH?
Authors: Gross Richard H
Published: April 2021

ABSTRACT: A survey of 74 skeletally mature patients with leg length discrepancies of 1.5 cm or more revealed that patients with less than a 2.0-cm discrepancy did not consider their short leg to be a problem in any way. As the amount of discrepancy increased, there were more problems, although there was no critical "cutoff" point. Some patients functioned well athletically with discrepancies of over 2.5 cm. A survey of pediatric orthopedists reflected the wide variety of opinion regarding indications for equalization of leg length discrepancy noted in the literature. It is concluded that there seems little indication for equalization of discrepancies less than 2 cm. For larger amounts of discrepancy, "clinical judgment" still must be weighed on an individual basis, as individual variation among patients with leg length discrepancy confounds any precise classification of functional disability.

COMBINED ANTICONVULSANT OSTEOMALACIA AND PAGET'S DISEASE: A CASE REPORT
Authors: Sherk Henry H , Bellin Harvey
Published: April 2021

ABSTRACT: In a 71-year-old woman with severe anticonvulsant osteomalacia and Paget's disease, vitamin D (50,000 units orally twice/week and 400 units orally daily) produced dramatic subjective improvement. Bone biopsies showed a striking increase in areas of mineralized bone after treatment, although the pagetoid appearance of bone trabeculae remained unchanged. The patient's blood and urinary calcium levels were low initially, and did not increase significantly after vitamin D administration. When Paget's disease is associated with anticonvulsant osteomalacia, moderately high doses of vitamin D may safely reverse the course of the osteomalacia and induce remineralization of the skeleton.
INTERNAL FIXATION IN THE HAND: A REVIEW OF INDICATIONS AND METHODS
Authors: Lucas George L
Published: April 2021

ABSTRACT: Despite the infrequent need for open reduction of hand fractures, the orthopedic surgeon must be aware of the indications for open reduction and/or internal fixation and must be able to apply the different methods of fixation in the appropriate circumstances. Joint injuries, compound finger injuries, and alignment or stabilization problems with the hand skeleton may mandate some type of internal fixation. Availability of small implants and reliable one-hand operated pin drivers for placement of stabilizing wires or wire loops for interosseous fixation are definite advances in treatment of fractures of the hand. Rigid internal fixation, with plates or screws, cannot be considered a panacea, but interosseous wire loop techniques should be given more consideration for stabilization of phalangeal fractures, in view of the excellent opposition, rigidity, compression of fracture fragments, and ease of application that this method provides. This article reviews the variety of ways in which internal fixation techniques can be applied to injuries of the hand skeleton.

Cementless Total Shoulder Arthroplasty: Preliminary Experience With Thirteen Cases
Authors: Faludi D Dennis , Weiland Andrew J
Published: April 2021

ABSTRACT: From February 1978 to March 1981, 13 English-McNab cementless, semiconstrained, implant shoulder arthroplasties were performed in 12 people. The ages of the patients at the time of surgery ranged from 53 to 73 years with an average of 62 years. The preoperative diagnoses were rheumatoid arthritis, primary osteoarthrosis, posttraumatic osteoarthritis, avascular necrosis, and failed hemiarthroplasty. Followup ranged from 27 to 62 months with an average of 44.3 months. Criteria for total shoulder replacement were intractable pain commensurate with destruction of the glenohumeral joint on x-ray. The UCLA shoulder rating system was used for evaluation of pain, function, muscle power, and motion.

Preoperative UCLA mean scores were 1.7 for pain, 1.8 for function, 4.0 for muscle power and motion. At followup, mean scores were 6.6, 5.6, and 4.8 respectively. Significant complications occurred.

Our conclusions are that uncemented total shoulder arthroplasty with an unconstrained prosthesis can, in selected patients, offer significant relief of pain and increase overall function while modestly improving strength and motion. The complications are consistent with those reported in the literature although loosening of this prosthesis has not been noted.
