description: Sugihara Chiune (1900–1986) was the only Japanese national recognized as a Righteous Among the Nations (or Righteous Gentile) by Yad Vashem in Jerusalem. He won this honor in 1985 because, in the summer of 1940, he issued 2160 transit visas to Japan that enabled some 6000 Jews, mostly Polish Jewish refugees, to escape from Lithuania by traveling via the Trans-Siberian Railway to Japan. After staying there for several months, most of the refugees moved on to Shanghai where they lived during the war; all survived. Sugihara was the Vice Consul of Japan in Kaunas at that time. Some of the people helped by Sugihara learned of his exploits in the late 1960s. His story spread and many myths followed. It was said that, by issuing the visas, he risked his own life and that of his family; that he was dismissed from the Japanese Foreign Ministry; and that he saved six thousand Jews from the Holocaust. Above all, many believed that he acted out of admiration for Jews. Recent research indicates that the story and his motivations were far more complex than they appear and that Sugihara acted for many reasons, among them his desire to help people in distress. The following essay will seek to dispel some of the myths and above all ask the question: Did he deserve the title of Righteous Among the Nations and if so, why was it awarded to him?

description: Edge shunts are among the main factors causing reduction in solar cell open circuit voltage that is why their isolation is one of the main steps in solar cell manufacturing. Many techniques have been employed to achieve this goal, e.g. plasma etching, grinding, wet etching, etc. Unfortunately, these methods have the disadvantages of being very expensive, single cell process and consume a lot of dangerous chemicals. This work introduces a simple technique for edge shunt isolation, by making a mechanical grove through the emitter and uses it as back contact. It was found that with this technique the solar cell open circuit voltage can be increased by an amount up to 200 mV. This technique is simple, cheap and environmentally friendly in the sense that it uses no chemicals.

description: Recently, strong AGN outbursts at the centers of galaxy clusters have been found. Using a simple model, we study particle acceleration around a shock excited by an outburst and estimate nonthermal emission from the accelerated particles. We show that emission from secondary electrons is consistent with the radio observations of the minihalo in the Perseus cluster, if there was a strong AGN outburst >~10^8 yrs ago with an energy of ~1.8x10^62 erg. The validity of our model depends on the frequency of the large outbursts. We also estimate gamma-ray emission from the accelerated particles and show that it could be detected with GLAST.

description: We present the observational results of Galactic HII region S294, using optical photometry, narrow-band imaging and radio continuum mapping at 1280 MHz, together with archival data from 2MASS, MSX and IRAS surveys. The stellar surface density profile indicates that the radius of the cluster associated with the S294 region is ~ 2.3 arcmin. We found an anomalous reddening law for the dust inside the cluster region and the ratio of total-to-selective extinction is found to be 3.8+-0.1. We estimate the minimum reddening E (B-V) = 1.35 mag and distance of 4.8+-0.2 kpc to the region from optical CC and CM diagrams. We identified the ionizing source of the HII region, and spectral type estimates are consistent with a star of spectral type ~ B0 V. The 2MASS JHKs images reveal a partially embedded cluster associated with the ionizing source along with a small cluster towards the eastern border of S294. The ionization front seen along the direction of small cluster in radio continuum and Halpha images, might be due to the interaction of ionizing sources with the nearby molecular cloud. We found an arc shaped diffuse molecular hydrogen emission at 2.12 micron and a half ring of MSX dust emission which surrounds the ionized gas in the direction of the ionization front. Self consistent radiative transfer model of mid- to far-infrared continuum emission detected near small cluster is in good agreement with the observed spectral energy distribution of a B1.5 ZAMS star. The morphological correlation between the ionised and molecular gas, along with probable time scale involved between the ionising star, evolution of HII region and small cluster, indicates that the star-formation activity observed at the border is probably triggered by the expansion of HII region.

Shrinking binary and planetary orbits by Kozai cycles with tidal friction
Creators: name: Fabrycky, Daniel

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: At least two arguments suggest that the orbits of a large fraction of binary stars and extrasolar planets shrank by 1-2 orders of magnitude after formation: (i) the physical radius of a star shrinks by a large factor from birth to the main sequence, yet many main-sequence stars have companions orbiting only a few stellar radii away, and (ii) in current theories of planet formation, the region within ~0.1 AU of a protostar is too hot and rarefied for a Jupiter-mass planet to form, yet many "hot Jupiters" are observed at such distances. We investigate orbital shrinkage by the combined effects of secular perturbations from a distant companion star (Kozai oscillations) and tidal friction. We integrate the relevant equations of motion to predict the distribution of orbital elements produced by this process. Binary stars with orbital periods of 0.1 to 10 days, with a median of ~2 d, are produced from binaries with much longer periods (10 d to 10^5 d), consistent with observations indicating that most or all short-period binaries have distant companions (tertiaries). We also make two new testable predictions: (1) For periods between 3 and 10 d, the distribution of the mutual inclination between the inner binary and the tertiary orbit should peak strongly near 40 deg and 140 deg. (2) Extrasolar planets whose host stars have a distant binary companion may also undergo this process, in which case the orbit of the resulting hot Jupiter will typically be misaligned with the equator of its host star.

description: We introduce a general operational characterization of information-preserving structures (IPS) -- encompassing noiseless subsystems, decoherence-free subspaces, pointer bases, and error-correcting codes -- by demonstrating that they are isometric to fixed points of unital quantum processes. Using this, we show that every IPS is a matrix algebra. We further establish a structure theorem for the fixed states and observables of an arbitrary process, which unifies the Schrodinger and Heisenberg pictures, places restrictions on physically allowed kinds of information, and provides an efficient algorithm for finding all noiseless and unitarily noiseless subsystems of the process.

description: In this paper we develop the theory of drift-diffusion on a semi-infinite Cayley tree with stochastic resetting. In the case of a homogeneous tree with a closed terminal node and no resetting, it is known that the system undergoes a classical localization-delocalization (LD) transition at a critical mean velocity $v_c= -(D/L)\ln (z-1)$ where $D$ is the diffusivity, $L$ is the branch length and $z$ is the coordination number of the tree. If $v v_c $ (diffusion-dominated delocalized state). This is equivalent to the transition between recurrent and transient transport on the tree, with the mean first passage time (MFPT) to be absorbed by an open terminal node switching from a finite value to infinity. Here we show how the LD transition provides a basic framework for understanding analogous phase transitions in optimal resetting rates. First, we establish the existence of an optimal resetting rate $r^{**}(z)$ that maximizes the steady-state solution at a closed terminal node. In addition, we show that there is a phase transition at a critical velocity $v_c^{**}(z)$ such that $r^{**}>0$ for $v>v_c^{**}$ and $r^{**}=0$ for $v

On the hybrid Davies like generator for quantum dissipation

Year: 2021
Subjects: subject: Quantum Physics (quant-ph)

description: We provide a class of quantum evolution beyond Markovian semigroup. This class is governed by a hybrid Davies like generator such that dissipation is controlled by a suitable memory kernel and decoherence by standard GKLS generator. These two processes commute and both of them commute with the unitary evolution controlled by the systems Hamiltonian. The corresponding memory kernel gives rise to semi-Markov evolution of the diagonal elements of the density matrix. However, the corresponding evolution needs not be completely positive. The role of decoherence generator is to restore complete positivity. Hence, to pose the dynamical problem one needs two processes generated by classical semi-Markov memory kernel and purely quantum decoherence generator. This scheme is illustrated for a qubit evolution.

description: The main purpose of this PhD dissertation was the investigation of the Water Footprint (WF) concept of the agricultural sector, on the Rhodes island. Initially the three WF components (blue, green and grey) of all the basic crops were calculated, with a distinction of rainfed and irrigated crops. In addition, WF benchmark values for the crops were estimated, as optimal reference levels and further investigation was performed on influence criteria of WF, in order to identify which factors are important in the development of WF benchmarks. Also, a financial index was calculated to investigate the correlation between the economic value and the blue WF of irrigated crops. Furthermore, a sensitivity analysis was performed on the values of blue, green, and grey WFs, taking into account fluctuations in the prices of certain key parameters. Finally, through a theoretical investigation, the WF contribution in correlation with the Green Marketing concept was identified.

description: We consider the formation of double white dwarfs (DWDs) through dynamical interactions in globular clusters. Such interactions can give rise to eccentric DWDs, in contrast to the exclusively circular population expected to form in the Galactic disk. We show that for a 5-year Laser Interferometer Space Antenna (LISA) mission and distances as far as the Large Magellanic Cloud, multiple harmonics from eccentric DWDs can be detected at a signal-to-noise ratio higher than 8 for at least a handful of eccentric DWDs, given their formation rate and typical lifetimes estimated from current cluster simulations. Consequently the association of eccentricity with stellar-mass LISA sources does not uniquely involve neutron stars, as is usually assumed. Due to the difficulty of detecting (eccentric) DWDs with present and planned electromagnetic observatories, LISA could provide unique dynamical identifications of these systems in globular clusters.

Patients' perceptions of risk factor modification following an acute myocardial infarction
Creators: name: Stewart, Sheila Margaret
Publisher: name: University of British Columbia
Year: 2010

description: This qualitative study was designed to explore the experience of risk factor modification from the perspective of patients who had sustained an acute myocardial infarction. Research has shown that modification of coronary risk factors including stopping smoking, reducing hypercholesterolemia and obesity, reducing hypertension, developing a habit of regular exercise, and developing methods to modify the coronary-prone behavior pattern reduces morbidity and mortality due to coronary heart disease. The literature reviewed indicated that cardiac rehabilitation programs are generally structured to provide the patient with information on coronary artery disease. However, it has been shown that information alone may not be enough to ensure that changes in behavior occur. Since there was a scarcity of information on measures to assist patients to modify their coronary risk factors, and as the literature indicated that the experience of risk factor modification had not been explored from patients' perspectives, a phenomenological design was therefore selected as the methodology for this study. Data were collected through twelve in-depth interviews with six participants. A guide of semi-structured questions was used for the initial interview and additional questions were generated from the data themselves. The constant comparative method of data analysis enabled the researcher to construct an analytic framework which represented patients' perceptions of their experiences in risk factor modification. In this framework, the central theme of patients' experiences was gaining mastery over their risk behavior(s). Gaining mastery occurred in three phases: searching for attribution, acknowledging risk, and attaining control. In attaining control, various cognitive and behavioral strategies were identified which led to a delineation of measures that could be provided to assist other patients in modifying their coronary risk factors. The findings demonstrated that a unique perspective of risk factor modification has been provided by patients based on their own experiences. It was also shown that intervention, consisting of teaching, counseling, and support, is essential to each phase of this process. The implications of this study focus on the importance of intervention in both in-hospital and out-patient cardiac rehabilitation programs. Intervention to assist patients to develop and use those skills that will enable them to gain a sense of mastery over their risk behaviors is essential if an initial or recurrent myocardial infarction is to be prevented. Implications for nursing practice, education, and research are outlined in light of the research findings.

description: In a quantum-noise limited system, weak-value amplification using post-selection normally does not produce more sensitive measurements than standard methods for ideal detectors: the increased weak value is compensated by the reduced power due to the small post-selection probability. Here we experimentally demonstrate recycled weak-value measurements using a pulsed light source and optical switch to enable nearly deterministic weak-value amplification of a mirror tilt. Using photon counting detectors, we demonstrate a signal improvement by a factor of $4.4 \pm 0.2$ and a signal-to-noise ratio improvement of $2.10 \pm 0.06$, compared to a single-pass weak-value experiment, and also compared to a conventional direct measurement of the tilt. The signal-to-noise ratio improvement could reach around 6 for the parameters of this experiment, assuming lower loss elements.

description: The aim of the present thesis was to investigate the expression level of Oct4B1 isoform and HERV-W1 transposable element, and the expression and methylation status of IGF2, MEST and PEG10 imprinted genes in samples of umbilical cord blood of newborns with different modes of conception and delivery. The groups examined were vaginal delivery, caesarean section with cephalic projection of the embryo, caesarean section with breech embryo projection and infants conceived through methods of assisted reproductive technology. These genes have a broad developmental effect on fetal growth and birth weight variation and their disruption is linked to low birth weight, metabolic disorders and cognitive impairment. On the other hand, Oct4B1 is a putative stem cell marker that warrants further investigation as a regulator of cellular stress response. There are studies reporting altered DNA methylation and expression levels of these genes after ART treatments. It is necessary to understand health risks and underlying molecular mechanisms of ART interventions, for the purpose of increasing the safety of these techniques. This doctorate thesis aims to stress the importance of evaluating the effect of environmental stressors on the epigenome. It can be considered as a starting point for more thorough investigations on the role of imprinted genes and Oct4B1 isoform on the regulation of human reproduction.

description: Recent results show that when non-linear electrodynamics is considered the no-scalar-hair theorems in the scalar-tensor theories (STT) of gravity, which are valid for the cases of neutral black holes and charged black holes in the Maxwell electrodynamics, can be circumvented. What is even more, in the present work, we find new non-unique, numerical solutions describing charged black holes coupled to non-linear electrodynamics in a special class of scalar-tensor theories. One of the phases has a trivial scalar field and coincides with the corresponding solution in General Relativity. The other four phases that we find are characterized by the value of the scalar field charge. The causal structure and some aspects of the stability of the solutions have also been studied. For the scalar-tensor theories considered, the black holes have a single, non-degenerate horizon, i.e., their causal structure resembles that of the Schwarzschild black hole. The thermodynamic analysis of the stability of the solutions indicates that a phase transition may occur.

description: Eclipsing planetary systems give us an important window on extrasolar planet atmospheres. By measuring the depth of the secondary eclipse, when the planet moves behind the star, we can estimate the strength of the thermal emission from the day side of the planet. Attaining a ground-based detection of one of these eclipses has proven to be a significant challenge, as time-dependent variations in instrument throughput and atmospheric seeing and absorption overwhelm the small signal of the eclipse at infrared wavelengths. We gathered a series of simultaneous L grism spectra of the transiting planet system TrES-1 and a nearby comparison star of comparable brightness, allowing us to correct for these effects in principle. Combining the data from two eclipses, we demonstrate a detection sensitivity of 0.15% in the eclipse depth relative to the stellar flux. This approaches the sensitivity required to detect the planetary emission, which theoretical models predict should lie between 0.05-0.1% of the stellar flux in our 2.9-4.3 micron bandpass. We explore the factors that ultimately limit the precision of this technique, and discuss potential avenues for future improvements.

description: We present a method to extract the phase shift of a scattering process using the real-time evolution in the early and intermediate stages of the collision in order to estimate the time delay of a wave packet. This procedure is convenient when using noisy quantum computers for which the asymptotic out-state behavior is unreachable. We demonstrate that the challenging Fourier transforms involved in the state preparation and measurements can be implemented in $1+1$ dimensions with current trapped ion devices and IBM quantum computers. We compare quantum computation of the time delays obtained in the one-particle quantum mechanics limit and the scalable quantum field theory formulation with accurate numerical results. We discuss the finite volume effects in the Wigner formula connecting time delays to phase shifts. The results reported involve two- and four-qubit calculations, and we discuss the possibility of larger scale computations in the near future.

description: In this paper, we study the feasibility of coupling the PN ranging with filtered high-order modulations, and investigate the simultaneous demodulation of a high-rate telemetry stream while tracking the PN ranging sequence. Accordingly, we design a receiver scheme that is able to perform a parallel cancellation, in closed-loop, of the ranging and the telemetry signal reciprocally. From our analysis, we find that the non-constant envelope property of the modulation causes an additional jitter on the PN ranging timing estimation that, on the other hand, can be limited by properly sizing the receiver loop bandwidth. Our study proves that the use of filtered high-order modulations combined with PN ranging outperforms the state-of-the-art in terms of spectral efficiency and achievable data rate, while having comparable ranging performance.

description: Οι ανθρώπινες σχέσεις αποτελούν ένα ενδιαφέρον πεδίο ερευνητικής δράσης ποικίλων επιστημών. Καθώς όμως η πολυπλοκότητα της άσκησης των καθηκόντων στα επαγγέλματα υγείας είναι τέτοια, ιδιαίτερη θέση στην ερευνητική δράση κατέχει η μελέτη της δυαδικής σχέσης ιατρού- ασθενούς. Το ενδιαφέρον για έρευνα επικεντρώνεται στην καταγραφή και ανάλυση της κοινωνικής θεωρίας, η οποία περικλείει τις πολύπλευρες κοινωνικό- ηθικές συνιστώσες της εν λόγω σχέσης. Αυτές οι συνιστώσες- ως καταγεγραμμένη παρακαταθήκη της ανθρώπινης διανόησης ανά τους αιώνες- βοηθούν στην αποκωδικοποίηση και την ερμηνεία της ανθρώπινης συμπεριφοράς. Η έρευνα η οποία ακολουθεί- ως μελέτη περίπτωσης- καταγράφει εμπειρικά την έκφραση της σχέσης ιατρού –ασθενούς, δια μέσου της ικανοποίησης των χρηστών – ασθενών από τις παρεχόμενες υπηρεσίες υγείας της Κλινικής του Εργαστηρίου Στοματολογίας του Οδοντιατρικού Tμήματος του Α.Π.Θ. Η δημιουργική σύζευξη θεωρητικού πλαισίου και ερευνητικής χροιάς προσδίδουν τα εχέγγυα καταγραφής προτάσεων βελτιωτικού τύπου, οι οποίες συντάσσονται υπέρ της βελτίωσης της ζωτικής επικοινωνίας του ιατρού με τον ασθενή και συνακολούθως υπέρ της περαιτέρω αναβάθμισης της ποιότητας των παροχών υγείας.
description: Human relations represent an interesting multidisciplinary research field. However, due to the complexity of the health professionals’ duties, the study of the physician-patient relationship plays a rather significant role in research. Interest focuses on recording and analysing social theory comprising all multiple socio-ethical components of the above mentioned relationship. Such components – as recorded over the centuries – promote deciphering and interpreting human behavior. The following study – as a case study – empirically captures the expression of the physician-patient relationship through user/patient satisfaction from the health services provided in the Dental Clinic of the Aristotle University of Thessaloniki. By creatively coupling theoretical framework with research, proposals for the improvements of the physician-patient vital communication and, consequently, the enhancement of health providers’ quality are guaranteed.

description: We performed optical-pump terahertz-probe measurements of a Mott insulator YTiO$_{3}$ and a band semiconductor Si using a laser diode (1.47 eV) and a femtosecond pulse laser (1.55 eV). Both samples possess long energy-relaxation times (1.5 ms for YTiO$_{3}$ and 15 $μ$s for Si); therefore, it is possible to extract terahertz complex conductivities of photoinduced carriers under equilibrium. We observed highly contrasting behavior - Drude conductivity in Si and localized conductivity possibly obeying the Jonscher law in YTiO$_{3}$. The carrier number at the highest carrier-concentration layer in YTiO$_{3}$ is estimated to be 0.015 per Ti site. Anisotropic conductivity of YTiO$_{3}$ is determined. Our study indicates that localized carriers might play an important role in the incipient formation of photoinduced metallic phases in Mott insulators. In addition, this study shows that the transfer-matrix method is effective for extracting an optical constant of a sample with a spatially inhomogeneous carrier distribution.

description: This dissertation explores the careers of nine mainstream African American female music stars that rose to fame during the second half of the twentieth century. The concept that motivates the entire study is that of the diva, with the main goal being the examination of how the latter term has determined these artists’ performances on their way in becoming influential figures in the broader American popular culture. Through a close reading of these artists’ body of work, including parts of their discography, filmography, videography, and memoirs this project aims at highlighting the diva as a timeless yet dynamic category of popular entertainment that is also a distinct musical product of America. This research also prompts an intense debate regarding matters of cultural, racial, and musical identities, while challenging established notions such as cultural authenticity and music genre. Ultimately, the diva emerges as an umbrella field that unifies all the different strands of the representations of black female musical artistry in America as they have come to fruition over a five decade period.
description: Η παρούσα διατριβή ερευνά εννέα δημοφιλείς Αφρικανο-Αμερικανίδες γυναίκες σταρ της μουσικής, των οποίων οι καριέρες αναπτύχθηκαν κατά το δεύτερο μισό του εικοστού αιώνα. Η κεντρική ιδέα της μελέτης συνολικά είναι η diva, ενώ ο κύριος στόχος είναι να αναδειχθεί η επιρροή αυτής της έννοιας στον τρόπο με τον οποίο έχει δομηθεί η παραστατική υπόσταση των συγκεκριμένων καλλιτέχνιδων στην διάρκεια της πορείας τους ως σημαίνουσες προσωπικότητες μιας ευρύτερης Αμερικανικής λαϊκής κουλτούρας. Μέσα από την μελέτη διαφόρων πτυχών του έργου τους, συμπεριλαμβανομένων της δισκογραφίας και φιλμογραφίας τους, όπως και των αυτοβιογραφιών τους, η διατριβή αυτή αναδεικνύει την diva ως μια διαχρονική αλλά και εξελίξιμη κατηγορία ψυχαγωγίας, η οποία ταυτόχρονα αποτελεί ένα χαρακτηριστικό μουσικό προϊόν της Αμερικής. Επιπλέον, επιχειρείται η επαναξιολόγηση ζητημάτων που άπτονται σε πολιτιστικές, φυλετικές, και μουσικές ταυτότητες, καθώς και σε έννοιες όπως η πολιτιστική αυθεντικότητα και το μουσικό είδος. Τέλος, η diva προβάλλεται ως ένα πεδίο-ομπρέλα το οποίο ενοποιεί τις ποικίλες διαστάσεις των αναπαραστάσεων της μαύρης γυναικείας μουσικής καλλιτεχνικότητας στην Αμερική όπως έχει αναπτυχθεί σε ένα διάστημα πέντε δεκαετιών.
Stephani-Schutz quantum cosmology

description: We study the Stephani quantum cosmological model in the presence of a cosmological constant in radiation dominated Universe. In the present work the Schutz's variational formalism which recovers the notion of time is applied. This gives rise to Wheeler-DeWitt equations which can be cast in the form of Schrödinger equations for the scale factor. We find their eigenvalues and eigenfunctions by using the Spectral Method. Then we use the eigenfunctions in order to construct wave packets and evaluate the time-dependent expectation value of the scale factor, which is found to oscillate between non-zero finite maximum and minimum values. Since the expectation value of the scale factor never tends to the singular point, we have an initial indication that this model may not have singularities at the quantum level.

description: We present the results of the Gemini Deep Planet Survey, a near-infrared adaptive optics search for giant planets and brown dwarfs around nearby young stars. The observations were obtained with the Altair adaptive optics system at the Gemini North telescope and angular differential imaging was used to suppress the speckle noise of the central star. Detection limits for the 85 stars observed are presented, along with a list of all faint point sources detected around them. Typically, the observations are sensitive to angular separations beyond 0.5" with 5-sigma contrast sensitivities in magnitude difference at 1.6 micron of 9.5 at 0.5", 12.9 at 1", 15.0 at 2", and 16.5 at 5". For the typical target of the survey, a 100 Myr old K0 star located 22 pc from the Sun, the observations are sensitive enough to detect planets more massive than 2 Mjup with a projected separation in the range 40-200 AU. Second epoch observations of 48 stars with candidates (out of 54) have confirmed that all candidates are unrelated background stars. A detailed statistical analysis of the survey results, yielding upper limits on the fractions of stars with giant planet or low mass brown dwarf companions, is presented. Assuming a planet mass distribution dN/dm m^{-1.2} and a semi-major axis distribution dN/da a^{-1}, the 95% credible upper limits on the fraction of stars with at least one planet of mass 0.5-13 Mjup are 0.28 for the range 10-25 AU, 0.13 for 25-50 AU, and 0.093 for 50-250 AU. The 95% credible interval for the fraction of stars with at least one brown dwarf companion having a semi-major axis in the range 25-250 AU is 0.019 (-0.015/+0.083), irrespective of any assumption on the mass and semi-major axis distributions. The stars HD 14802, HD 166181, and HD 213845 have been resolved into binaries for the first time.

The frequency and perceived effectiveness of coping strategies used by registered nurses returning to university
Creators: name: Thompson, Mary Catherine
Publisher: name: University of British Columbia
Year: 2010

description: This study examines the stress and coping behaviors of registered nurses returning to school to pursue a baccalaureate degree in nursing (returning RNs). The sample included 72 volunteers who were returning RNs currently enrolled in a nursing program. Data were collected using the Ways of Coping Checklist and the Personal Strain Questionnaire which assessed the causes of stress related to attending school/ the use of specific coping behaviors, and the effectiveness of those coping behaviors in reducing stress. The major sources of stress included: 1. school-related stressors such as lack of academic skills and concerns with the program and faculty, 2. social and domestic concerns, 3. lack of time, and 4. lack of money. The study concludes that coping strategies used most frequently were also rated as most effective. These coping strategies dealt directly with the stressor or the emotional reaction to it by problem-solving or seeking social support. Coping strategies seldom used and rated as ineffective, on the other hand, avoided dealing with the stressor, for example, by the use of wishful thinking. After an initial term at school, returning RNs, who had not been students for at least two years, had no more distress than returning RNs who had attended school recently. Returning RNs In the fourth year of the program were less stressed by school-specific stressors such as study skills and managing school assignments than were students in the third year. This implies that these students learn to cope with stressors, a process which could perhaps be facilitated through an orientation program. In summary, the majority of returning RNs cope quite well in the present structure by using the strategies of problem-solving and seeking social support. Implications for nursing education are discussed and areas for further research are identified.
