3D forward modeling of upgoing and downgoing wavefields using Hilbert transform
Authors: Zheng Yikang , Wang Yibo , Chang Xu
Published: October 2017

The separation of upgoing and downgoing wavefields is an important technique in the processing of vertical seismic profiling data and ocean bottom cable data. It is also used in reverse time migration (RTM) based on the two-way wave equation to suppress low-frequency, high-amplitude noises and false images. Therefore, we model upgoing and downgoing wavefields directly in the wavefield propagation. There are several methods to obtain separated wavefields. The methods using the Fourier transform require storage of the wavefields, which is not practical due to the extremely high disk-space requirements. Methods using Poynting vectors have an ambiguity problem when crossing a peak or a trough of the wavefields. To improve the accuracy and stability of the modeled upgoing and downgoing wavefields in a complicated velocity model, we evaluate an efficient forward-modeling approach purely based on the Hilbert transform in 3D acoustic wavefield simulation. This method is implemented by the Hilbert transform along the time and depth axis, instead of the Fourier transform. We explicitly derive the formulas for upgoing and downgoing wavefield propagation and attach reproducible source codes. Applications to synthetic models indicate that this method can forward propagate upgoing and downgoing wavefields effectively and improve the imaging quality in migration. This method has various potential applications, e.g., 3D seismic imaging with high computation efficiency.

Published: October 2017

Context

Insulin action in the human brain influences eating behavior, cognition, and whole-body metabolism. Studies investigating brain insulin rely on intranasal application.

Objective

To investigate effects of three doses of insulin and placebo as nasal sprays on the central and autonomous nervous system and analyze absorption of insulin into the bloodstream.

Design, Participants, and Methods

Nine healthy men received placebo or 40 U, 80 U, and 160 U insulin spray in randomized order. Before and after spray, brain activity was assessed by functional magnetic resonance imaging, and heart rate variability (HRV) was assessed from electrocardiogram. Plasma insulin, C-peptide, and glucose were measured regularly.

Setting

General community.

Results

Nasal insulin administration dose-dependently modulated regional brain activity and the normalized high-frequency component of the HRV. Post hoc analyses revealed that only 160 U insulin showed a considerable difference from placebo. Dose-dependent spillover of nasal insulin into the bloodstream was detected. The brain response was not correlated with this temporary rise in circulating insulin.

Conclusions

Nasal insulin dose-dependently modulated regional brain activity with the strongest effects after 160 U. However, this dose was accompanied by a transient increase in circulating insulin concentrations due to a spillover into circulation. Our current results may serve as a basis for future studies with nasal insulin to untangle brain insulin effects in health and disease.
“One Can Veil and Be a Singer!”
Authors: Hemmasi Farzaneh
Published: October 2017

This article explores the media controversy surrounding the victory of Ermia, a veiled female vocalist, on the 2013 expatriate Iranian talent competition Googoosh Music Academy (GMA). A historically and ethnographically informed “ethnotextual” analysis of a selection of Persian-language television programs, articles and news reports, weblogs, and Facebook posts responding to Ermia reveals how a reality television contestant came to disturb simplistic but powerful binaries of modest/immodest, religious/secular, Iranian/Western, and national/diasporic as she combined signifying elements of these positions into one unsettling figure. The article shows how Ermia’s case gathered political valence through the contentious transnational Iranian mediascape and the televised talent genre’s premise—representing “real,” “ordinary” contestants and fostering audience participation. I argue that GMA became a space for publicly playing with cultural norms, political participation, and the politics of piety at some distance from the pressures that make publicly living difference so challenging.
Online and Off the Field: Predicting School Choice in College Football Recruiting from Social Media Data
Authors: Bigsby Kristina Gavin , Ohlmann Jeffrey W. , Zhao Kang
Published: October 2017

This study explores predictors of school choice decisions in American college football recruitment. We combine data about individual athletes’ recruiting activities with social media data to predict which school the athlete will choose among those that have offered him a scholarship. While previous works have approached school choice as a rational decision process, our results indicate that a bounded rationality model incorporating social factors and heuristics may be more appropriate. We explore how the actions taken by athletes during recruitment can be interpreted as early signals of athletes’ preferences and find that models incorporating social media features consistently outperform the baseline model with only off-line recruiting features. In addition to better understanding the school choice decision, this work can help coaches to effectively allocate recruiting resources and inform social media strategies during recruitment.
A Direct Test of Agency Theories of Debt: Evidence from Residential Mortgage-Backed Securities
Authors: Huang Yilin , Nadauld Taylor D.
Published: October 2017

When a firm is facing default, equity holders have incentives to engage in asset substitution, underinvest, or directly transfer wealth. Few papers document investment distortions on account of debt-equity agency conflicts, only that the threat of distortions influence ex ante financing costs. A nonagency residential mortgage-backed security deal represents an entity that is highly leveraged where, ex ante, equity holders know they will face default. This provides an ideal laboratory for testing whether the threat of default creates any of the distortions predicted in theory. We estimate a lower bound on agency costs associated with direct wealth transfers to be in the range of $.018 per dollar.

Ideal Clutters That Do Not Pack
Authors: Abdi Ahmad , Pashkovich Kanstantsin , Cornuéjols Gérard
Published: October 2017

For a clutter 𝒞 over ground set E, a pair of distinct elements e, f ∈ E are coexclusive if every minimal cover contains at most one of them. An identification of 𝒞 is another clutter obtained after identifying coexclusive elements of 𝒞. If a clutter is nonpacking, then so is any identification of it.

Inspired by this observation, and impelled by the lack of a qualitative characterization for ideal minimally nonpacking (mnp) clutters, we reduce ideal mnp clutters even further by taking their identifications. In doing so, we reveal chains of ideal mnp clutters, demonstrate the centrality of mnp clutters with covering number two, as well as provide a qualitative characterization of irreducible ideal mnp clutters with covering number two. At the core of this characterization lies a class of objects, called marginal cuboids, that naturally give rise to ideal nonpacking clutters with covering number two. We present an explicit class of marginal cuboids, and show that the corresponding clutters have one of Q6, Q2, 1, Q10 as a minor, where Q6, Q2, 1 are known ideal mnp clutters, and Q10 is a new ideal mnp clutter.
Palliative care for people living with end-stage pulmonary disease
Authors: Pople Josephine
Published: October 2017

Twenty years ago, the case was made for people with life-limiting medical conditions other than cancer to receive specialist palliative care services. The recommendation came from the National Council for Hospice and Specialist Palliative Care Services ( Addington Hall, 1998 ). Since then, research and practice have developed to make this a reality. We now see people with non-curative medical conditions, often referred to as being in the end stages of their chronic condition, receiving care and treatment by palliative care practitioners. There is, however, a long way to go before the rhetoric of ‘palliative care for all’ becomes a reality. Few people with end-stage pulmonary disease have access to hospice and specialist palliative care services. This article focuses on end-stage pulmonary disease, a term that encompasses all non-malignant, chronic lung conditions that progress to end-of-life care. An overview of the pathophysiology of the condition is given. Focus is placed on the stages of the disease and common patient problems, using case studies to highlight how the disease processes develop to become end stage and require palliative care. The article highlights the need for care planning at the end of life and the palliative care measures required to ensure good quality care centred on both physical and psychosocial aspects.

Palliative care for people with advanced major neuro-cognitive disorders
Authors: Crowther Jacqueline , Costello John
Published: October 2017

Major neuro-cognitive disorders are life-limiting illnesses. However, unlike other life-limiting illnesses, the disease trajectory is often long, protracted and unpredictable. Prognostication of end of life can be problematic and access to specialist palliative care services, including hospice, are limited, variable and inequitable, resulting in negative experiences at this time. Major neuro-cognitive disorders will be discussed initially in broad terms, considering the most common types and symptoms. Palliative and end-of-life care, including legal and ethical issues, are addressed and awareness raised of different types of major neuro-cognitive disorders, common symptoms and common nursing problems associated with major neuro-cognitive disorders at end of life. The needs of family and lay caregivers, who form an important part of the overall experience of major neuro-cognitive disorders, are also highlighted. Advance Care Planning is an important part of end-of-life care. Some of the challenges involved in facilitating Advanced Care Planning (ACP) with people with major neuro-cognitive disorders and caregivers are also considered. The need for palliative care practitioners to recognise the individuality of the patient and be aware that not all patients experiencing major neuro-cognitive disorders share the same set of symptoms, as in other life limiting illnesses, is also highlighted. It is important for specialist palliative care practitioners to recognise the transferability of existing knowledge, skills and expertise to the care of people with advanced major neuro-cognitive disorders as end of life approaches. Collaboration, partnership and the sharing of knowledge and skills is crucial to the development of good end-of-life care for people with these conditions, development of the workforce and the creation of positive experiences and subsequent memories after death.

Lost in translation? The challenges of measuring informal care among children and young people
Authors: Kelly Grace , Devine Paula , McKnight Martina
Published: October 2017

This article uses data from the 2015 Young Life and Times and Kids’ Life and Times surveys to discuss the methodological challenges of identifying young carers in surveys. The article considers how children’s interpretation of ‘caring’ might not correspond with the definition of ‘young carer’ that adults wish to capture. This article discusses how prior consultation with young carers to improve understanding did not have the outcome anticipated. It advises that consultation should be carried out with young carers and their non-caregiving peers together, allowing space for ‘co-reflexive practice’.
PHDA: Afinal, qual a sua origem? Uma revisão dos fatores etiológicos
Authors: Oliveira Luís , Medeiros Maria , Serrano Ana
Published: October 2017

A Perturbação de Hiperatividade/Défice de Atenção (PHDA) e as suas possíveis causas continuam a ser motivo de controvérsia. Este artigo resulta de uma pesquisa atualizada em diferentes revistas e livros da especialidade e pretende dar uma explicação acerca das principais causas etiológicas da PHDA: (i) genéticas/hereditárias; (ii) neurobiológicas e neuropsicológicas; (iii) outros fatores etiológicos com origem pré, péri e pós-natal; e (iv) fatores contextuais. Atualmente, sabe-se que a PHDA é uma condição de natureza multidimensional, cuja confluência de diferentes fatores endógenos e exógenos resulta numa expressão heterogénea dos seus principais sintomas ao longo da vida (i.e., desatenção, hiperatividade e impulsividade). Conhecendo realmente a natureza do problema, saberemos (todos, mas em particular os professores e outros agentes educativos) melhor como agir com estes sujeitos, principalmente em contexto escolar.

Authors: França Matheus Filipe de Moraes Sousa , Vilela Michelle Souza , Costa Anne Pinheiro , Nogueira Isadora , Pires Márcio De Carvalho , Souza Nara Oliveira Silva
Published: October 2017

Basil (Ocimum spp.) is an essential oil producing plant and it is used as a condiment for diferent foods, besides serving as raw material for medicinal purposes. This crop has also been showing great importance as an ornamental plant in recent years. However, basil lacks studies concerning its different usages with special regards to its ornamental potential. Therefore, this study aimed at evaluating the vegetative development and the ornamental potential of the basil cultivars ‘Grecco a Palla’ (O. minimum), ‘Alfavaca Basilicão Vermelho’ (O. basilicum), and ‘Thai Basil’ (O. basilicum), under protected cultivation. The following characteristics were evaluated: germination percentage, germination speed index, plant canopy diameter (cm), leaf and inflorescence length (cm), plant height (cm), and fresh and dry leaf mass (g). The ornamental potential was estimated based on visual evaluations of plant canopy volume; leaf shape, texture, size, and color; stem and flower color; and number of days to flowering. Cultivar ‘Thai Basil’ presented the highest leaf dry mass and ‘Grecco a Palla’ showed the highest germination speed index and seed germination percentage. All cultivars bloomed within 60 days after planting and exhibited color and brightness variability, which are desirable traits for a landscape composition. ‘Grecco a Palla’ stood out for its short and compact inflorescences, dwarf size and globular shape when grown as a potted plant. The studied cultivars demonstrated favorable characteristics for ornamental usage based on visual assessments.
Predictors of High-Sensitivity Cardiac Troponin T Elevation in Patients with Acute Paroxysmal Supraventricular Tachycardia and Ischemic Heart Disease

Published: October 2017

We studied the predictors and patterns of high-sensitivity cardiac troponin T (hs-cTnT) elevation in patients with paroxysmal supraventricular tachycardia (PSVT) in the presence and absence of ischemic heart disease.

During calendar year 2013, we enrolled 70 of 72 consecutive adult patients with PSVT who presented at our center within 4 hours after the onset of tachycardia. On the basis of increased hs-cTnT at either of 2 initial measurements, we divided patients into groups (hs-cTnT–positive and hs-cTnT–negative), to study the predictors of enzyme elevation. We then divided the hs-cTnT–positive patients into 2 groups—those with and those without ischemic heart disease—and compared hs-cTnT changes.

We observed hs-cTnT elevation in 52 of the 70 patients (74.3%). The hs-cTnT–positive patients were significantly older (P=0.008) and had a significantly higher duration of tachycardia (P=0.01). Older age, the presence of chest pain, lower diastolic blood pressure, and longer duration of tachycardia increased the odds of enzyme elevation. Among patients with elevated hs-cTnT levels, the baseline and maximal hs-cTnT levels were significantly higher in ischemic patients (P=0.01 and P=0.003, respectively). The increase in hs-cTnT seemed to be higher and longer in ischemic patients, although this was not statistically significant (P=0.908). Finally, hs-cTnT did not decrease to baseline levels within 48 hours in either group.

We found that hs-cTnT levels increased in all our patients with PSVT, more so in those with ischemic heart disease.

Published: October 2017

Understanding plaque formation in patients at risk for coronary artery disease—the leading cause of morbidity and death in the world—enables physicians to better determine whether and how to treat these individuals. We used computed tomographic angiography to quantitatively evaluate the progression of nonculprit coronary plaques along the full length of the right coronary artery in 21 patients with acute coronary syndrome. Each right coronary artery was analyzed in sequential, 3-mm-long segments, and the minimum luminal area, plaque burden, and plaque volume within each segment were evaluated at baseline and at 12-month follow-up. Serial remodeling of the right coronary artery was also evaluated. In total, 625 arterial segments were analyzed. At 12-month follow-up, the plaque burden had increased slightly by 0.34% (interquartile range [IQR], −4.32% to 6.35%; P=0.02), and the plaque volume was not significantly changed (0.33 mm3; IQR, −3.05 to 3.54; P=0.213). The minimum luminal area decreased 0.05 mm2 (IQR, −1.33 to 0.87 mm2; P=0.012), and this was accompanied by vessel reduction, as evidenced by negative remodeling in 43% of the 625 segments. We conclude that serial computed tomographic angiography can be used to quantitatively evaluate the morphologic progression of coronary plaques.
Tolerance of Sustained Ventricular Fibrillation During Continuous-Flow Left Ventricular Assist Device Support

Published: October 2017

The widespread use of continuous-flow left ventricular assist devices for mechanical circulatory support has shown that long-term hemodynamic support is possible, even when a clinical “pulse” cannot be detected. We present the incidental discovery of ventricular fibrillation in 6 alert, hemodynamically stable patients supported only by a continuous-flow device (HeartMate II, n=5; Jarvik 2000, n=1). Ventricular fibrillation was found in 3 patients during routine outpatient follow-up visits and in 3 awaiting discharge from the hospital after device placement. Diagnosis was confirmed by electrocardiographic and echocardiographic studies.

The average duration of mechanical circulatory support before ventricular fibrillation occurred was 221 ± 362 days (range, 5–864 d). All patients were conscious and ambulatory at the time of the arrhythmia. Three patients reported symptoms—primarily fatigue, nausea, and exertional dyspnea—that prompted evaluation. Serum chemistry analysis of blood drawn immediately after diagnosis showed no changes that suggested end-organ dysfunction. Three patients died of unrelated complications an average of 3.9 yr (range, 360–2,270 d) after the event. Two of the remaining 3 patients eventually underwent successful pump explantation, and one is on ongoing support.

Our experience shows that it is possible for patients with continuous-flow left ventricular assist devices to remain hemodynamically stable while in ventricular fibrillation. Additional investigation is needed to determine whether defibrillator settings for these patients should be adjusted to limit delivery of shock therapy.
Left Circumflex Coronary Artery as the Culprit Vessel in ST-Segment-Elevation Myocardial Infarction

Published: October 2017

The prevalence of the left circumflex coronary artery (LCx) as the culprit vessel in ST-segment-elevation myocardial infarction (STEMI) is reportedly lowest among that of the 3 main epicardial arteries, and has not been described for non-STEMI (NSTEMI) and stable angina pectoris. We sought to define the distribution of culprit arteries in these clinical presentations and suggest mechanisms for the differences.

We reviewed 189 coronary angiograms of patients with STEMI, 203 with NSTEMI, and 548 with stable angina (n=940), and compared distributions of stenotic and culprit coronary arteries (lesions prompting intervention).

Obstructive coronary lesions (≥50% narrowing) were more prevalent in the left anterior descending coronary artery (LAD) (36%–38%) and similar in the LCx and right coronary artery (RCA) (27%–29%), regardless of clinical presentation (P <0.01). In NSTEMI and stable angina, culprit vessels and total obstructive disease had the same distribution. In STEMI, however, a culprit LCx was significantly less prevalent (17%) than was total obstructive disease (27%; P <0.01), or a culprit LAD (47%) or RCA (34%) (both P <0.001). In our computed tomographic angiographic model of coronary longitudinal strain (percentage of shortening), LCx strain was only 1.5% ± 2.4%, versus 9.5% ± 2.9% for LAD strain and 10.1% ± 3.9% for RCA strain.

In STEMI, LCx plaques seem less prone to rupturing. Culprit and total disease distributions are similar in NSTEMI and angina, suggesting a different ischemic pathophysiology in these presentations. Lower LCx longitudinal strain might contribute to reduced plaque rupture in STEMI.
Managing Stenotic Septal Perforator Branches
Authors: Saidi Abdulfattah , Tandar Anwar , Welt Frederick G.P. , Owan Theophilus
Published: October 2017

Coronary artery disease of the septal perforator branches can lead to clinical ischemia and conduction abnormalities. Performing interventional procedures in these vessels is frequently impossible because they are small, which makes it difficult to approach them and to select appropriate equipment. Larger septal perforator branches have been treated percutaneously in a few patients; however, the clinical effectiveness and long-term outcomes are not known. We present our experience in managing obstructive septal perforator branch stenosis in 4 patients.

Published: October 2017

Allergy to contrast media is hazardous in patients who need multiple cardiac catheterizations. We describe the case of a 16-year-old boy who presented with fatigue and cyanosis. He had undergone a Fontan operation 14 years previously, after which he developed an allergy to iodinated contrast media. Contrast echocardiograms by manual injection of microbubbles suggested the presence of a venovenous collateral vessel from the brachiocephalic vein draining into the pulmonary vein. We used intravascular ultrasound as the sole imaging method to identify the target vessel and to guide deployment of an Amplatzer Vascular Plug II. The patient experienced immediate improvement in his systemic saturation. Our experience shows that intravascular ultrasound may be a feasible alternative to standard imaging methods in patients with congenital heart disease who need cardiac interventional procedures and are allergic to contrast media.
Gender Equality in Climate Change Adaptation: A Case of Cirebon, Indonesia
Authors: Pratiwi Nila Ardhyarini H. , Rahmawati Yovi Dzulhijjah , Setiono Ivo
Published: October 2017

Climate change will greatly affect many aspects of Indonesia’s economy, society, and environment. The vulnerability of individuals to climate change will depend on their adaptive capacity and manifestations of gender inequality can affect this capacity. It is generally acknowledged that women may be more vulnerable to climate change impact than men. Therefore, gender inequality becomes the critical issue on climate change adaptation. However, it is not yet mainstreamed into climate change adaptation program in Indonesian cities. With regard to such circumstance, this study assessed the gender dimensions in the context of climate change vulnerability, and how to mainstream gender-sensitive into climate change adaptation program at the local level with a case of Cirebon, Indonesia, in urban and rural areas. Mixed methods were employed for this study by combining quantitative and qualitative analysis through explanatory and comprehensive analysis. We examined the gender differences on socio-economic condition by using the socio-ecological model with various variables consisting of literacy and education, livelihood, access to and control over resources, health, mobility, female-headed household, and roles in decision-making. The results highlight that there are different gender’s adaptive capacities between urban and rural areas to climate change, and gender mainstreaming in climate change adaptation in an urban area is easier to be implemented than in a rural area which influenced by the level of society and policymakers ability and awareness.

The Diffusion of the Codex
Authors: Harnett Benjamin
Published: October 2017

The adoption of the codex for literature in the Roman world was one of the most significant developments in the history of the book, yet remains poorly understood. Physical evidence seems to contradict literary evidence from Martial's epigrams. Near-total adoption of the codex for early Christian works, even as the book roll dominated non-Christian book forms in the first centuries of our era, has led to endless speculation about possible ideological motives for adoption. What has been unquestioned is the importance of Christian scribes in the surge of adoption from 300 C.E. onward. This article reexamines the foundation of many theories, the timeline for non-Christian adoption sketched by Roberts and Skeat in their study, The Birth of the Codex, and reevaluates it through the lens of “diffusion of innovations theory” in order to reconcile the evidence and elevate practical considerations once and for all over ideological motives.
An Australian Our Lady
Authors: Kahl Janet
Published: October 2017

This article offers a description of three Australian Marian pilgrimage sites—Penrose Park (Roman Catholic), Yankalilla (Anglican), and Coogee (post-Christian). At Penrose Park, devotion to the Virgin Mary reveals its deep roots in Catholicism through the presence of traditional motifs found at global Marian shrines such as Czestochowa, Lourdes, and Fatima. The Yankalilla shrine, formed within traditional Anglican parameters, also contains familiar Marian symbolism but has adopted non-institutional and non-Christian ideas that are attractive to spiritual seekers and are part of popular culture. At Coogee, the Virgin Mary emerged outside the confines of formal religious tradition. Thus is the Australian “Our Lady” framed by international motifs from transnational shrines yet identified with uniquely local bushland and beach settings along with elements from Australian culture and history.
Our Lady of Zeitoun (1968–1971)
Authors: Westbrook Donald A.
Published: October 2017

This article situates the mass mariophanies reported at Zeitoun (Cairo), Egypt, from 1968 to 1971 in their historical, political, interfaith, and ecumenical contexts. The series of luminous apparitions above St. Mary’s Coptic Orthodox Church were first observed by nearby Muslim public transit workers. Soon after, the site attracted tens of thousands of Christian and Muslim pilgrims, many of whom observed bright light in the form of the Virgin Mary in addition to other manifestations, such as dove-shaped lights hovering above or near the church. Miraculous healings were also reported. The Zeitoun apparitions serve as a unique instance within the broader study of Marian apparitions by providing a non-Catholic example that took place within a Muslim-majority nation over a span of nearly three years. Moreover, full contextualization of the events in Zeitoun requires interdisciplinary attention spanning Middle Eastern, Islamic, and ecumenical studies; as such, the apparitions invite further and fuller examination in the secondary literature.

Published: October 2017

Durante la Edad Moderna, las elites eclesiásticas: obispos, capellanes, predicadores o confesores, especialmente cuando formaban parte de la corte o participaban en los principales órganos de la Administración –consejos, juntas, secretarías...- tendieron a ejercer una doble influencia no sólo como guias espirituales, sino como consejeros políticos. En este contexto, el objetivo de nuestro trabajo es prestar atención a la labor del confesor del rey en la Monarquía hispánica durante el siglo XVII, intentando ofrecer una primera aproximación en relación a su integración, influencia y actitud en diferentes instituciones de la Administración.

El objetivo de este trabajo es ofrecer una lectura de la realidad que afectó a las órdenes religiosas y al clero regular durante el siglo XVIII que no se agote en el estudio de la acción política del reformismo borbónico. Las consideraciones sobre los regulares y su papel fueron cada vez más críticas. Mostraremos, por un lado, cómo esas opiniones fueron compartidas por diferentes sectores de la sociedad, más allá de las élites gobernantes y de la minoría de intelectuales y presentaremos algunas de las manifestaciones e indicativos más claros de lo que entendemos fue un proceso de desafección social y no sólo política. Por otro lado, explicaremos cómo algunas de las líneas de la acción ilustrada y de la política reformista repercutieron también en la situación de los religiosos, erosionando las bases sobre las que se asentaba su poder y su economía y veremos cómo además esas medidas que se iban tomando encontraron el respaldo de las autoridades locales y de otros sectores de las villas y poblaciones, es decir, tuvieron un apoyo social más amplio.

Nuestros objetivos en este artículo han sido dos: a) Medir, a partir de las fuentes existentes para la segunda mitad del siglo XVIII, la extensión del régimen señorial gallego y de sus distintas modalidades, tanto en población sometida como en extensión superficial, lo que ha permitido conocer y poderar a los titulares del señorío; b) Establecer, a través de muestras representativas, una evaluación de peso de las cargas señoriales para los vasallos y del beneficio material para los señores, en cada una de las diferentes modalidades del señorío.
Un estudio sobre el entorno urbano de la Coruña en el S. XVIII: el ámbito de lo cotidiano
Authors: Sampaio Seoane Eva
Published: October 2017

A partir de los inventarios post-morten hemos intentado reconstruir la vida cotidiana de la Coruña de finales del Antiguo Régimen. De esta forma hemos pasado revista a cuestiones en apariencia banales como la distribución interior de las viviendas, ubicación y composición de los muebles más frecuentes, así como los motivos decorativos más usuales. Quizá lo más destacable sea la sobriedad y precariedad de medios en las condiciones de vida, austeridad que cambia radicalmente durante el último tercio del siglo XVIII para dar paso a un lujo y una suntuosidad inimaginables décadas atrás, que afecta a todos los grupos sociales, aunque se ponga de manifiesto más rapidamente en las categorías socioeconómicas más elevadas.

Familia y explotación agropecuaria del interior coruñés a mediados del siglo XVIII
Authors: Sandoval Verea Francisco M.
Published: October 2017

Partiendo del Catastro de la Ensenada (1752) se ofrece una aproximación, en clave demográfica y socioeconómica, a la familia de una zona de transición a la Galicia interior -comarca de Ordes (A Coruña)-. Un área geográdica caracterizada por bajas densidades humanas, un desigual reparto de la riqueza rústica, y predominio de hogares de estructura nuclear y tamaño medio. Se comprueba como a lo largo del ciclo familiar se produce un ajuste permanente entre las características del agregado doméstico y las de la explotación agropecuaria.
Los productos alimentarios de ultramar en la agricultura de los países mediterráneos
Authors: Eiras Roel Antonio
Published: October 2017

Se contempla en este trabajo el impacto de los nuevos cultivos traídos de América por los españoles (calabaza, tomate, pimiento, etc. y principalmente habichuela, maíz y patata) en la economía agraria y en la alimentación de los países mediterráneos. Utilizando el criterio de análisis del costo por kilocaloría, se deduce que su incidencia en la economía popular fue muy superior a la de un remoto precursor índico, el arroz. Se intenta trazar el periplo cronológico de la difusión de los nuevos cultivos, y las razones de su rápida adaptación; así como sus efectos en relación con el crecimiento demográfico y con la evolución del poder adquisitivo del salario de las masas urbanas.
La transformación de la familia europea, siglos XVI-XX
Authors: Wall Richard
Published: October 2017

Con una gama mayor de datos respecto a los empleados en su día por J. Hajnal y P. Laslett, se pretende en este trabajo afinar la regionalización que ambos abordaron a partir de las variaciones de las formas familiares en Europa. También precisar cual ha sido la evolución de dichas formas en el contexto europeo entre 1750 y 1950, el caso inglés y la defnición de las cateracterísticas de los sistemas familiares y de los hogares en la Europa del pasado.
Sobre los fundamentos teóricos de un concepto del discurso histórico: civilización
Authors: Goberna Falque Juan Ramón
Published: October 2017

El concepto de civilización sirve, en buena medida, para ocultar una serie de hechos que no se considera conveniente explicitar: a saber, el de su asociación con una clase o grupo de privilegiados que son los creadores y detentadores del mismo, y el hecho de que se basa en una estructura catóptrica, es decir, la estructura de un espejo. La noción de civilización, o su consideración como "hecho" es un espejo en el que el historiador se puede contemplar con satisfacción, al comprobar que la "realidad" corresponde a las más nítidas de sus aspiraciones y a los más reconditos de sus deseos. El historiador puede, pues, disfrutar de su propia contemplación sin sentirse culpable, a la vez que impone su propia figura, toda su esencia, al resto de la colectividad.
Una visión en panorámica de la hidalguía gallega
Authors: Migués Rodríguez Vítor Manuel
Published: October 2017

Se trata de un estudio en panorámica de una pequeña nobleza europea del Antiguo Régimen (en este caso la gallega -fidalguía-), con características más autóctonas que la gran nobleza, más homogénea a nivel europeo.Un análisis más profundo de las fuentes reveló la importancia de las mismas y su perniciosidad para los estudios de la fidalguía, una clase social poco tocada por la historiografía tradicional gallega. A fin de paliar este vacío se estudió la Casa de San Fiz de Asma y sus agregadas, precipitado institucional con una clara estrategia de reproducción social: el matrimonio.La formación dominial de la hidalguía y sus actividades económicas revelan una base rentista fundamentada en un intenso programa de compras que están capitalizadas por una o varias personalidades individuales que fundaron y desarrollaron estas Casas, muchas veces asentadas en pocas generaciones. Por otra parte, las anexiones de solares, agudizadas en el siglo XVIII, provocaron una reordenación institucional de la pequeña nobleza gallega, que a finales del Antiguo Régimen está representada por un grupo de Casas de gran poder.El nivel de vida del grupo se analiza a través de la casa física -en minúscula-, exterior e interiormente, revelando una gran variedad y austeridad como norma común. Además, el concepto de hidalguía aplicado a esta élite se basa en la opinión y sanción populares más que en fundamentos legales.La hidalguía gallega se mantuvo firme y dominadora en el siglo XIX, ascendiendo en muchos casos a la titulación, pero revelando una actitud conservadora muy diferente a la manifestada durante su crecimiento y desarrollo a finales del siglo XVI y primera mitad del XVII.

Atypical Case of Partial Anomalous Pulmonary Venous Connection Misdiagnosed as Primary Pulmonary Arterial Hypertension
Authors: Lu Shuyang , Wei Lai , Wang Chunsheng
Published: October 2017

In this case report, we present the delayed diagnosis of an atypical partial anomalous pulmonary venous connection, which was initially misdiagnosed as primary pulmonary arterial hypertension. It was difficult to make a conclusive diagnosis using transthoracic echocardiography (TTE), because the two high right superior pulmonary veins drained into the superior vena cava and limited the shunt of patent foramen ovale. Preoperative TTE only showed right heart volume overload, pulmonary arterial hypertension, and severe tricuspid valve insufficiency. A chest CT-angiography (angio-CT) finally found the anomalous right superior pulmonary venous connection, which was further confirmed by surgery. The postoperative course was uneventful.

Background: Legitimacy of entry-oriented therapy for DeBakey I aortic dissection is of eminent importance in the era of emerging ascending aorta endovascular therapy. This study aims to evaluate early, midterm, and reintervention results of entry-oriented operative strategy compared to more aggressive strategies for treatment of DeBakey type I aortic dissection with an isolated intimal tear in the ascending aorta.Methods: This study prospectively followed 98 consecutive patients who received an operation for DeBakey type I aortic dissection with the intimal tear in the ascending aorta between 2007 and 2013 for up to 6 years. Follow-up included survival, medical therapy, CT-imaging results, and reinterventions. Patients were grouped into entry-oriented (group I) receiving an isolated replacement of the ascending aorta and/or hemiarch (65 patients); and aggressive therapy (group II) receiving a replacement of the ascending aorta and complete aortic arch (33 patients). Results: The in-hospital mortality was 19% and 23% respectively. The 3-year survival was 52% and 47% respectively (P = .193). Group II showed no advantage regarding persistence or progression of the dissection, thrombosis of false lumen, increase in aortic diameter, peripheral organ malperfusion (as assessed by follow-up computed tomography imaging) or freedom from reintervention. Conclusion: In treating DeBakey I aortic dissection with an entry tear in the ascending aorta, it might be legitimate to adopt an entry-oriented operative strategy. Further research is also needed to clearly describe the indication of extending the operative strategy in such cases.
