A Qualitative Evaluation of Patient-Perceived Benefits and Barriers to Participation in a Telephone Care Management Program
Authors: Jubelt Lindsay E. , Volpp Kevin G. , Gatto Dana E. , Friedman Joelle Y. , Shea Judy A. 
Published: January 2015

Purpose. To examine why high-risk individuals targeted for a telephone care management program participated at low rates. Design. Study design consisted of qualitative, semistructured interviews. Setting. The setting was a large national insurer's telephone-based care management program. The program employed registered nurses to provide individually tailored education and counseling about health and health care. Subjects. Study subjects comprised members of a national insurer who were recruited to participate in a care management program but had either dropped out of the program after a short period of initial engagement or had never participated despite recruitment efforts. Measures. Interview content was divided into four categories: knowledge of the case management program, barriers to program participation, perceptions of benefits of the program, and suggestions for program improvement. Analysis. Investigators conducted a directed content analysis. Results. The most commonly cited barriers to participation were a lack of perceived need and a sense of distrust toward the program and its staff. The most commonly cited benefits were psychosocial support and goal setting. Conclusion. Care management programs may benefit from changes to how insurance plan members are selected for the program and from adjusting program content to address perceived needs among members.

Purpose To describe in vivo longitudinal modifications of the Ozurdex intravitreal implant using spectral-domain optical coherence tomography (SD-OCT) over a 6-month period in an eye treated for retinal vein occlusion (RVO). Methods Case report. Results An 82-year-old woman with severe macular edema secondary to branch RVO received an Ozurdex intravitreal implant in the left eye. At day 1, SD-OCT showed that the implant was completely filled with highly reflective dexamethasone. At day 30, complete resolution of macular edema on SD-OCT was noted. At day 60, macular edema started to relapse; SD-OCT scans over the implant showed highly reflective borders that appeared irregular and focally retracted, while the majority of the internal drug had been washed out. At day 180, macular edema returned to baseline levels; SD-OCT scans over the implant showed that the device was contracted with almost complete absence of the internal lumen and drug. Conclusions Using SD-OCT, we demonstrated that 60 days postinjection most dexamethasone had been released from the Ozurdex implant, which showed multiple irregularities. This was associated with recurrence of macular edema that became worse after 180 days, when there was no residual dexamethasone remaining in the shrunken implant. Low steady levels of the drug in the vitreous and lower biological activity in the retina after the 2-month high-dose release phase may explain why a large number of patients lose clinical improvement 60 days postinjection, as shown by pivotal clinical trials.

Purpose About 8 years ago, we approached an intraoperative transluminal angioplasty (ITA) performed during the arteriovenous fistula (AVF) creation, to treat arterial or venous stenosis diagnosed by a preliminary ultrasound examination. Objective of this study is to validate the efficacy of ITA. Methods Early failure (EF) and failure to mature (FTM) were evaluated in 69 AVFs with ITA created in 58 patients in the last 3 years. In the same period, 160 patients received 188 AVFs without ITA and were considered control group. Of the two groups, age, comorbid factors, sex, primary and secondary patency rate (PR) were also analysed. Results The two groups were homogeneous for gender and age (70.4 + 11.1 years of ITA group vs. 66.3 + 14.4, p = 0.059). The incidence of diabetes, heart disease and peripheral artery disease was higher in the ITA group (43% vs. 17%, p<0.0001, 35% vs. 6%, p<0.0001 and 56% vs. 15%, p<0.0001, respectively). EF and FTM occurred in seven and eight cases in the ITA group and in 15 and 13 cases in the controls, respectively. Total failure occurred in 24% of ITA group and 14% of the controls (p = 0.2). The primary PR at 6, 12 and 24 months was 78%, 72% and 59% for ITA group and 85%, 78% and 78 % for control group (p<0.01). The secondary PR at 6, 12 and 24 months was 91%, 86% and 80% for ITA group and 95%, 95% and 92% for the controls (p<0.01). Conclusions Our ITA approach has allowed satisfactory results in patients at a high risk of AVF failure.
Resolution of severe vertigo in a remote location by the modified Epley maneuver

Published: January 2015

Benign paroxysmal positional vertigo (BPPV) is an extremely common cause of peripheral vertigo. BPPV is believed to be caused by the presence of tiny crystals in the semicircular canals. It is typically diagnosed from a patient's history and examination.
A 55-year-old lady dialed the emergency services due to severe vertigo and vomiting for about two hours. The previous night she travelled around 250 miles in her caravan to North Wales, UK, for a holiday. No ambulance was available to be dispatched, hence the ambulance control contacted the local general practitioner doctor on duty to attend to the patient. The patient was suffering from recurrent vertigo symptoms for nearly two years, despite being on medications. She described her symptoms as room spinning when she wanted to get out of the bed which was associated with vomiting. History and examination revealed no signs attributing to acute stroke.
After performing the Dix-Hallpike test, the doctor confirmed the diagnosis of posterior canal BPPV and the patient was offered the modified Epley maneuver. Post-maneuver, a significant improvement in her symptoms was noticed within a few minutes. On arrival of ambulance crew after an hour, the patient decided not to go to hospital as her symptoms were almost 90 percent better. This case highlights the need for awareness among family medicine and emergency doctors to diagnose and treat BPPV with a physical maneuver rather than medications.
Interaction of von Willebrand factor with platelets and the vessel wall
Authors: Mendolicchio G. L. , Ruggeri Z. M. 
Published: January 2015

SummaryThe initiation of thrombus formation at sites of vascular injury to secure haemostasis after tissue trauma requires the interaction of surface-exposed von Willebrand factor (VWF) with its primary platelet receptor, the glycoprotein (GP) Ib-IX-V complex. As an insoluble component of the extracellular matrix (ECM) of endothelial cells, VWF can directly initiate platelet adhesion. Circulating plasma VWF en-hances matrix VWF activity by binding to structures that become exposed to flowing blood, notably collagen type I and III in deeper layers of the vessel along with microfibrillar collagen type VI in the sub endothelium. Moreover, plasma VWF is required to support platelet-to-platelet adhesion – i. e. aggregation – which promotes thrombus growth and consolidation. For these reasons, understanding how plasma VWF interaction with platelet receptors is regulated, particularly any distinctive features of GPIb binding to soluble as opposed to immobilized VWF, is of paramount importance in vascular biology.This brief review will highlight knowledge acquired and key problems that remain to be solved to elucidate fully the role of VWF in normal haemostasis and pathological thrombosis.
Aproximación a la figura de una matrona romana culta y poderosa. El caso de Julia Domna.
Authors: Caravaca Guerrero Consuelo Isabel 
Published: January 2015

El propósito de este trabajo es realizar una síntesis de las fuentes primarias que hablan de Julia Domna – destacando a Dión Casio, Herodiano, Historia Augusta y Flavio Filóstrato – y los estudios modernos principales, con el objetivo de conocer el papel e influencia que debió de ejercer esta mujer. Su papel no solo se basó en ser matrona, sino que consiguió ser esposa y madre de emperadores. Honrada con numerosos adjetivos como Augusta, Pía, Felix o mater Augustorum y mater castrorum, su influencia se extendió por todo el Imperio. Nos encontramos así, ante una figura que se salió de los márgenes impuestos por la sociedad romana a las mujeres.
This work is aimed to do a synthesis of every primary source that speaks about Julia Domna – specially Dion Casio, Herodiano, Historia Augusta and Flavio Filostrato – as well as the main modern studies, with the objective of knowing the role and influence this woman might have exercised.Her role was not only based on the fact she was a midwife, but she also managed to be a wife and an emperor’s mother. Honoured with several adjectives such as Augusta, Pía, Felix or mater Augustorum and mater castrorum, her influence spread all over the Empire. Therefore, we are dealing with a figure that went out from the margins imposed to women by the Roman society.
Odiseo a través de la parodia. Desmitificación e ironía de una Ítaca nostálgica en Prometeo de Pérez de Ayala y ¿Por qué corres, Ulises? de Gala.
Authors: López López Carmen María 
Published: January 2015

El objetivo de este artículo es proponer un estudio crítico-comparado a partir de las variaciones del modelo épico en dos obras de la literatura española del siglo XX: Prometeo de Ramón Pérez de Ayala y ¿Por qué corres, Ulises? de Antonio Gala. Para ello, se trazará una perspectiva histórica de acuerdo con algunos de los episodios homéricos insertos en la Odisea: la estancia del héroe con Nausica en la tierra de los feacios, con la ninfa Calipso en Ogigia, con la maga Circe en la isla de Eea, en la tierra de los Lotófagos, la Nekuia o descenso al Hades y el reencuentro con Penélope.Por último, este artículo pretende analizar el sentido de la risa desde la tradición, con la finalidad de atender a la reinterpretación del mito como parodia e ironía respecto del relato homérico.
The aim of this article is to propose a critical and comparative study beginning from the epic model variations on the Spanish Literature from the twentieth century: Prometeo by Ramón Pérez de Ayala and ¿Por qué corres, Ulises? by Antonio Gala. To this purpose, a historic perspective will be designed, according to some Homeric episodes inside of the Odisea: the stay of the hero with Nausicaa in the phaeacians’ land, with the nymph Calypso in Ogygia, with the magician Circe in the Eea’s island, in the Lotofagi’s land, the Nekuia and the re-encounter with Penelope. To conclude, this article pretends to analyze the sense of the laugh from the tradition, to deal with the reinterpretation of the myth as a parody and an irony regarding the Homeric narration.

Discrete event simulation of Maglev transport considering traffic waves
Authors: Cha Moo Hyun , Mun Duhwan 
Published: January 2015

Abstract
A magnetically levitated vehicle (Maglev) system is under commercialization as a new transportation system in Korea. The Maglev is operated by an unmanned automatic control system. Therefore, the plan of train operation should be carefully established and validated in advance. In general, when making a train operation plan, statistically predicted traffic data is used. However, a traffic wave often occurs in real train service, and demand-driven simulation technology is required to review a train operation plan and service quality considering traffic waves. We propose a method and model to simulate Maglev operation considering continuous demand changes. For this purpose, we employed a discrete event model that is suitable for modeling the behavior of railway passenger transportation. We modeled the system hierarchically using discrete event system specification (DEVS) formalism. In addition, through implementation and an experiment using the DEVSim++ simulation environment, we tested the feasibility of the proposed model. Our experimental results also verified that our demand-driven simulation technology can be used for a priori review of train operation plans and strategies.
Tangible AR interaction based on fingertip touch using small-sized nonsquare markers
Authors: Park Hyungjun , Jung Ho-Kyun , Park Sang-Jin 
Published: January 2015

Abstract
Although big-sized markers are good for accurate marker recognition and tracking, they are easily occluded by other objects and deteriorate natural visualization and level of immersion during user interaction in AR environments. In this paper, we propose an approach to exploiting the use of rectangular markers to support tangible AR interaction based on fingertip touch using small-sized markers. It basically adjusts the length, width, and interior area of rectangular markers to make them more suitably fit to longish objects like fingers. It also utilizes convex polygons to resolve the partial occlusion of a marker and properly enlarges the pattern area of a marker while adjusting its size without deteriorating the quality of marker detection. We obtained encouraging results from users that the approach can provide better natural visualization and higher level of immersion, and be accurate and tangible enough to support a pseudo feeling of touching virtual products with human hands or fingertips during design evaluation of digital handheld products.
Interannual variability of the northwestern Iberia deep ocean: Response to large‐scale North Atlantic forcing
Authors: Prieto E. , González‐Pola C. , Lavín A. , Holliday N. P. 
Published: January 2015

AbstractThe oceanic hydrography of the north‐easternmost region of the North Atlantic subtropical gyre has been monitored since 2003 by three sections extending between 100 and 200 nautical miles from the Spanish NW and N coast into the Atlantic and the Bay of Biscay. The sections were occupied twice a year from 2003 to 2010, annually after that, and measure the whole water column (>5000 m). Correlation of series in the vertical and among sections, autocorrelation and estimates of the effect of the noise induced by the mesoscale field, all indicate that observed signatures are robust changes of water masses at the regional scale. The hydrographic time series are not characterized by smooth trends but instead by shifts that persist through consecutive cruises. The most notable features include a shift to more saline central waters around 2005 after which they remained stable, and a decrease in thermohaline properties of the Labrador Sea Water from autumn 2008 to 2010. Years with a strong winter North Atlantic Oscillation (NAO) index are characterized by shifts in thermohaline properties across most of the intermediate levels, with the most notable event being the warming and increasing salinity that followed the large NAO index drop of 2010. The observations are consistent with current understanding of the large‐scale functioning of the North Atlantic, which predicts a northeastward expansion of subtropical temperate waters in the eastern boundary as a response to NAO forcing. The observed variability is discussed in relationship to large‐scale circulation.
Auditor Independence
Authors: Gwilliam David , Marnet Oliver 
Published: January 2015

AbstractThe concept and notion of auditor independence has been of key importance to the audit profession, and to the variety of stakeholders who rely upon the work of auditors, for more than one hundred and fifty years. This contribution seeks to bring forward a number of the issues which underpin the concept together with a brief review both of recent regulatory developments and empirical evidence which seeks to consider whether auditors are in fact independent in practice.At one level the economic dependence of auditors on clients on whose financial statements they are providing an opinion suggests a prima facie lack of independence. Beyond this however there are perhaps wider and more subtle issues as to the manner in which auditors obtain, collate and evaluate the information which they rely upon to come to their opinion – sometimes termed epistemological independence – and, and to an extent interlinked, the range and variety of behavioural, cultural and judgemental biases which may act to impact on that opinion.There are however a range of factors which act to constrain auditors from behaving in a non‐independent manner. These include the professional training of auditors, the significant adverse economic out‐turns which may result from the provision of an inappropriate audit opinion, and the range of regulatory review and indeed sanctions – including those relating to corporate governance – which seek to ensure that auditors do carry out their work and make their judgements in an independent manner.The nature of regulatory and governance change at both national and supra‐national levels in recent years is reviewed briefly as is the quite extensive, albeit rather mixed, empirical evidence as to the nature of auditor independence. This empirical evidence focuses on both stakeholder perceptions and also attempts to link aspects of independence with both client reporting behaviour and actual auditor judgements. The reader is directed to references which allow this literature to be explored in greater depth.
AIDS
Authors: Dunn Craig P. 
Published: January 2015

AbstractAIDS is an acronym for “acquired immunodeficiency syndrome.” AIDS is generally, although not universally, thought to be associated with the presence of HIV, the human immunodeficiency virus. Evidence suggests that HIV is spread through transmission of bodily fluids typically associated with intimate sexual contact and/or intravenous drug use, though cases of in utero mother‐to‐child transmission are on the rise. HIV is fragile once outside the body, and is therefore not transmittable through casual contact. AIDS is treatable but not curable. With proper treatment, it is not unusual for individuals to live 10 years or even longer from time of initial diagnosis with HIV to eventual death. Ethical questons around addressing AIDs in the workplace highlight tensions among competing rights, utilitarian concepts for the greatest good, communitarian concerns and the ethics of care.
Economic Justice
Authors: Shaw William H. 
Published: January 2015

AbstractOn what basis should economic goods and services be distributed? There are various intuitively plausible principles, such as need or desert, which seem to work in some circumstances, but not others. Accordingly, some philosophers have advanced more comprehensive accounts of economic justice, in particular, utilitarianism, libertarianism, and Rawls's social contract theory. Recently, increased attention has been given to questions of global economic justice.
Advertising, Ethics of
Authors: Laczniak Gene R. 
Published: January 2015

AbstractThe economic importance of advertising and its social visibility brings it under great public scrutiny. Advertising is by definition, one‐sided persuasive communications using mass media to promote a product or service. Critics argue that it violates the principle of fairness by depriving consumers of unbiased input necessary to make an informed decision. Supporters contend that the vast majority of advertisers provide useful information allowing consumers to glean facts that enhances the efficiency of the product selection process. Government regulation and controls, industry self‐regulation, and the inherent professional ethic in the industry all serve to mitigate the most obvious forms of deception and unfairness.
Bribery
Authors: D'Andrade Kendall 
Published: January 2015

Abstract
Interest in bribery as a topic in business ethics comes from claims that certain payment should not be counted as bribes, or that, even though they are bribes, they are still acceptable, generally as the lesser of two evils. To retain our moral intuitions that bribery and extortion are morally objectionable, we will need to accept some limits on freedom of exchange. If the payments have some effect on the recipient, even one he is unaware of, then they function to affect his action and his reasons for choosing, and so are bribes.
