Factors that motivate RNs to return to school for the BSN and to remain in school to complete the degree

This exploratory descriptive study examined the factors that influence Registered Nurses (RNs) to return to school to pursue a Baccalaureate of Science in Nursing degree (BSN) and the factors that contribute to the decision to remain in school to complete the degree. Students (N = 226) enrolled in RN-BSN programs in three different universities in southeast Florida participated in the study by completing researcher developed questionnaires. The study group included 140 students who were newly enrolled in an RN-BSN program and 86 students who were preparing to graduate from an RN-BSN program. The instruments used in this study were two researcher developed questionnaires, the Corbett Nursing Educational Motivational Inventory - Form A (CNEMI-A), administered to the newly enrolled students, and the Corbett Nursing Educational Motivational Inventory - Form B (CNEMI-B), administered to the graduating students. The questionnaires included researcher-developed items in addition to items derived from a modified form of the Educational Participation Scale used by other researchers. Demographic data were also collected. Findings indicated that changes in health care, career goals, personal satisfaction, and flexible curriculum patterns are the major reasons why RNs return to school for the BSN. Less significant factors were social support, salary increase, and employer expectations. The factors considered most significant in the decision to remain in school to complete the degree were ranked in the following order: personal achievement, changes in health care, career change/advancement, enrollment options, faculty support, social support, and employer support. Implications for nurse educators related to the changing roles of RNs and the need to continue to assist RNs to adapt to new roles in health care. Recommendations for future research on RN-BSN nursing education included studies to identify the courses considered most useful by RN-BSN students as compared to courses considered repetitive of basic nursing programs. Studies were also recommended to examine the differences between the needs of RNs related to experience as an RN and recency of education. Additional studies were recommended to determine the feasibility of dual-enrollment ADN/BSN programs for last semester ADN students. ^

The knowledge and use of critical thinking teaching strategies of faculty in associate degree nursing education programs

The purpose of this study was to determine the knowledge and use of critical thinking teaching strategies by full-time and part-time faculty in Associate Degree Nursing (ADN) programs. ^ Sanders CTI (1992) instrument was adapted for this study and pilot-tested prior to the general administration to ADN faculty in Southeast Florida. This modified instrument, now termed the Burroughs Teaching Strategy Inventory (BTSI), returned reliability estimates (Cronbach alphas of .71, .74, and .82 for the three constructs) comparable to the original instrument. The BTSI was administered to 113 full-time and part-time nursing faculty in three community college nursing programs. The response rate was 92% for full-time faculty (n = 58) and 61% for part-time faculty (n = 55). ^ The majority of participants supported a combined definition of critical thinking in nursing which represented a composite of thinking skills that included reflective thinking, assessing alternative viewpoints, and the use of problem-solving. Full-time and part-time faculty used different teaching strategies. Full-time faculty most often used multiple-choice exams and lecture while part-time faculty most frequently used discussion within their classes. One possible explanation for specific strategy choices and differences might be that full-time faculty taught predominately in theory classes where certain strategies would be more appropriate and part-time faculty taught predominately clinical classes. Both faculty types selected written nursing care plans as the second most effective critical thinking strategy. ^ Faculty identified several strategies as being effective in teaching critical thinking. These strategies included discussion, case studies, higher order questioning, and concept analysis. These however, were not always the strategies that were used in either the classroom or clinical setting. ^ Based on this study, the author recommends that if the profession continues to stress critical thinking as a vital component of practice, nursing faculty should receive education in appropriate critical teaching strategies. Both in-service seminars and workshops could be used to further the knowledge and use of critical thinking strategies by faculty. Qualitative research should be done to determine why nursing faculty use self-selected teaching strategies. ^

Haematite natural crystals: non-linear initial susceptibility at low temperature

Several works have reported that haematite has non-linear initial susceptibility at room temperature, like pyrrhotite or titanomagnetite, but there is no explanation for the observed behaviours yet. This study sets out to determine which physical property (grain size, foreign cations content and domain walls displacements) controls the initial susceptibility. The performed measurements include microprobe analysis to determine magnetic phases different to haematite; initial susceptibility (300 K); hysteresis loops, SIRM and backfield curves at 77 and 300 K to calculate magnetic parameters and minor loops at 77 K, to analyse initial susceptibility and magnetization behaviours below Morin transition. The magnetic moment study at low temperature is completed with measurements of zero field cooled-field cooled and AC susceptibility in a range from 5 to 300 K. The minor loops show that the non-linearity of initial susceptibility is closely related to Barkhausen jumps. Because of initial magnetic susceptibility is controlled by domain structure it is difficult to establish a mathematical model to separate magnetic subfabrics in haematite-bearing rocks.

Postbrexit: una Europa confusa, entre el desánimo y la incertidumbre

Este Editorial reflexiona sobre las causas que han llevado al Brexit: el desprecio a las instituciones europeas, ocultar sus logros como propios de los Gobiernos, la inadecuada gestión de la crisis, la emergencia y la tolerancia hacia los partidos populistas, el declive del continente...También se analiza el procedimiento para la retirada (art. 50 TUE) -manteniendo la tesis del paralelismo entre procedimiento de adhesión y de retirada-, así como las adaptaciones institucionales necesarias, además de las respuestas de fondo para proseguir con un proceso que comenzó antes del ingreso del Reino Unido y proseguirá sin este país.

Análisis del establecimiento de la longitud telomérica durante el desarrollo temprano en los mamíferos

Los telómeros se encuentran en el foco de atención de muchas investigaciones por su papel en el mantenimiento de la integridad cromosómica y su implicación en procesos como el envejecimiento, el cáncer y la regeneración tisular. En ausencia de mecanismos compensatorios, el ADN telomérico sufre un acortamiento progresivo en cada división celular debido a la incapacidad de las ADN polimerasas convencionales de replicar el extremo 5’ de los cromosomas. La telomerasa, una ribonucleoproteína con actividad transcriptasa inversa (componente TERT), compensa el acortamiento telomérico sintetizando las secuencias teloméricas de novo en el extremo 3’ de los cromosomas utilizando como molde una molécula de ARN asociada (componente TERC). La mayoría de los tipos celulares presentan una actividad telomerasa limitada, acortándose los telómeros en cada división mitótica. Por ello, la actividad de la telomerasa y el acortamiento telomérico son factores limitantes en la esperanza de vida de los mamíferos, mientras que el acortamiento de los telómeros contribuye al envejecimiento limitando la regeneración tisular. Durante el desarrollo embrionario los telómeros se alargan, quedando determinadas las reservas teloméricas con las que contará el recién nacido. Por este motivo, el estudio de la dinámica de la elongación telómerica y su regulación durante el desarrollo embrionario temprano en mamíferos es de gran interés debido a las implicaciones que la longitud telomérica (LT) del recién nacido tiene en las etapas posteriores del desarrollo...

Error tolerance of topological codes with independent bit-flip and measurement errors

Topological quantum error correction codes are currently among the most promising candidates for efficiently dealing with the decoherence effects inherently present in quantum devices. Numerically, their theoretical error threshold can be calculated by mapping the underlying quantum problem to a related classical statistical-mechanical spin system with quenched disorder. Here, we present results for the general fault-tolerant regime, where we consider both qubit and measurement errors. However, unlike in previous studies, here we vary the strength of the different error sources independently. Our results highlight peculiar differences between toric and color codes. This study complements previous results published in New J. Phys. 13, 083006 (2011).

Design rationnel de nanothermomètres programmables à base d’ADN

Développer de nouveaux nanomatériaux, interrupteurs et machines nanométriques sensibles à de petites variations de température spécifiques devrait être de grande utilité pour une multitude de domaines œuvrant dans la nanotechnologie. De plus, l’objectif est de convaincre le lecteur que les nanotechnologies à base d’ADN offrent d’énormes possibilités pour la surveillance de température en temps réel à l’échelle nanométrique. Dans la section Résultats, nous exploitons les propriétés de l’ADN pour créer des thermomètres versatiles, robustes et faciles à employer. En utilisant une série de nouvelles stratégies inspirées par la nature, nous sommes en mesure de créer des nanothermomètres d’ADN capables de mesurer des températures de 25 à 95°C avec une précision de <0.1°C. En créant de nouveaux complexes d’ADN multimériques, nous arrivons à développer des thermomètres ultrasensibles pouvant augmenter leur fluorescence 20 fois sur un intervalle de 7°C. En combinant plusieurs brins d’ADN avec des plages dynamiques différentes, nous pouvons former des thermomètres montrant une transition de phase linéaire sur 50°C. Finalement, la vitesse de réponse et la précision des thermomètres développés et leur réversibilité sont illustrées à l’aide d’une expérience de surveillance de température à l’intérieur d’un unique puits d’un appareil de qPCR. En conclusion, les applications potentielles de tels nanothermomètres en biologie synthétique, imagerie thermique cellulaire, nanomachines d’ADN et livraison contrôlée seront considérées.
