EVOLUTION AND INFLUENCING FACTORS OF THE GREEN DEVELOPMENT SPATIAL ASSOCIATION NETWORK IN THE GUANGDONG-HONG KONG-MACAO GREATER BAY AREA
Authors: Feng Zhijun , Chen Zinan , Cai Hechang , Yang Zaoli
Published: March 2022

Accurately grasping the structural characteristics and influencing factors of green development spatial association are significant for green coordinated development and ecological civilization construction in the Guangdong-Hong Kong-Macao Greater Bay Area (GBA). This study evaluates the GBA’s green development performance from 2015 to 2019 based on duality theory, and uses social network analysis to explore the structural characteristics and evolution of the green development spatial association network, and then uses the exponential random graph model to reveal the influencing factors of network formation. we find that: (1) the GBA’s green development is steady. Its spatial association network became increasingly complex, and tends to be tight. (2) As important hubs, Guangzhou, Shenzhen, and Hong Kong have the dominant positions in the GBA’s green development spatial association network. Huizhou, Jiangmen, Zhaoqing, and Macao are at the edge of the network, and their interoperability with other cities is relatively weak. (3) Four subgroups exist in the GBA during different periods, with obvious gradient characteristics between them, and the multilevel transmission mechanism of the green development network gradually forms. (4) Economic development and urbanization level, ecological environment endowment, and geographical, institutional, and industrial proximity all have significant impacts on the formation of the GBA’s green development spatial association network.

The Extremely Large Telescope and the Thirty Meter Telescope will use state of the art multiconjugate adaptive optics (MCAO) systems to obtain the full D
4 advantage that their apertures can provide. However, to reach the full astrometric potential of these facilities for on-sky science requires understanding any residual astrometric distortions from these systems and find ways to measure and eliminate them. In this work, we use Gemini multiconjugate adaptive optic system (GeMS) observations of the core of NGC 6723 to better understand the on-sky astrometric performance of MCAO. We develop new methods to measure the astrometric distortion fields of the observing system, which probe the distortion at the highest possible spatial resolution. We also describe methods for examining the time-variable and static components of the astrometric distortion. When applied to the GeMS Gemini South Adaptive Optics Imager (GSAOI) data, we are able to see the effect of the field rotator at the subpixel level, and we are able to empirically derive the distortion due to the optical design of GeMS/GSAOI. We argue that the resulting distortion maps are a valuable tool to measure and monitor the on-sky astrometric performance of future instrumentation. Our overall astrometry pipeline produces high-quality proper motions with an uncertainty floor of ∼45 μas yr−1. We measure the proper motion dispersion profile of NGC 6723 from a radius of ∼10″ out to ∼1′ based on ∼12,000 stars. We also produce a high-quality optical–near infrared color–magnitude diagram, which clearly shows the extreme horizontal branch and main-sequence knee of this cluster.
An Automatic Identification Method for the Photoelectron Boundary at Mars
Authors: Wang Yuqi , Cao Yutian , Cui Jun , Wei Yong , Rong Zhaojin
Published: March 2022

The photoelectron boundary (PEB) at Mars is defined to be the boundary separating the photoelectron-dominated ionosphere from the external plasma environment. Extensive studies have been presented to analyze the PEB variation in the Martian dayside ionosphere. However, the PEB was identified manually in previous studies because of the difficulty in detecting the faint photoelectron features at high altitudes. In this study, we develop an algorithm to detect these faint features and identify the location of PEB from energetic electron measurements automatically. We apply the algorithm to the measurements by the Solar Wind Electron Analyzer instrument on board the Mars Atmosphere and Volatile Evolution mission and identify a total number of 15,681 PEB crossing events accumulated from 2015 January to 2019 October, of which 9169 PEB are on the dayside and 6912 are on the nightside. Our analysis indicates that the altitude of the identified PEB tends to increase with solar extreme ultraviolet radiation and crustal magnetic field strength, in agreement with previous findings. By contrast, the PEB altitude on the nightside tends to increase dramatically with solar zenith angle but is found to be weakly influenced by the crustal magnetic field strength.

Published: March 2022

We present ALMA high-angular-resolution (∼50 au) observations of the Class I binary system SVS13-A. We report images of SVS13-A in numerous interstellar complex organic molecules: CH3OH, 13CH3OH, CH3CHO, CH3OCH3, and NH2CHO. Two hot corinos at different velocities are imaged in VLA4A (V
sys = +7.7 km s−1) and VLA4B (V
sys = +8.5 km s−1). From a non-LTE analysis of methanol lines, we derive a gas density of 3 × 108 cm−3 and gas temperatures of 140 and 170 K for VLA4A and VLA4B, respectively. For the other species, the column densities are derived from an LTE analysis. Formamide, which is the only N-bearing species detected in our observations, is more prominent around VLA4A, while dimethyl ether, methanol, and acetaldehyde are associated with both VLA4A and VLA4B. We derive in the two hot corinos abundance ratios of ∼1 for CH3OH, 13CH3OH, and CH3OCH3; ∼2 for CH3CHO; and ∼4 for NH2CHO. The present data set supports chemical segregation between the different species inside the binary system. The emerging picture is that of an onion-like structure of the two SVS13-A hot corinos, caused by the different binding energies of the species, also supported by ad hoc quantum chemistry calculations. In addition, the comparison between molecular and dust maps suggests that the interstellar complex organic molecules emission originates from slow shocks produced by accretion streamers impacting the VLA4A and VLA4B disks and enriching the gas-phase component.
Lack of genetic structure suggests high connectivity of Parnassius phoebus between nearby valleys in the Alps
Authors: Jaun Andreas , Wymann Hans-Peter , Lucek Kay
Published: March 2022

The spatial scale of intraspecific genetic connectivity and population structure are important aspects of conservation genetics. However, for many species these properties are unknown. Here we used genomic data to assess the genetic structure of the small Apollo butterfly (Parnassius phoebus Fabricius, 1793; Lepidoptera: Papilionidae) across three nearby valleys in the Central Swiss Alps. One of the valleys is currently used for hydropower production with future plans to raise the existing dam wall further. We found no significant genetic structure, suggesting a currently high connectivity of this species in our studied region.
Caring for Patients While Respecting Their Privacy: Renewing Our Commitment
Authors: Erickson Jeanette , Millar Sally
Published: March 2022

In 1996, HIPAA or the Health Insurance Portability and Accountability Act (HIPAA) was enacted into law. This law has had a significant impact on the health care industry including the need for numerous changes in the way we communicate with our patients, their families, and with each other. This law provides rights to patients and safeguards for employees. It affects everyone in a health care setting. Since the days in which the Nightingale Pledge was written, nursing has stressed the importance of confidentiality regarding all patient matters. The current Code of Ethics for Nurses (ANA, 2001) is clear in intent and meaning as it relates to the nurse’s role in promoting and advocating for patient’s rights related to privacy and confidentiality. For nurses, HIPAA is an endorsement of our previously articulated responsibility to our patients. The purpose of this article is to remind nurses of the importance of keeping patient information private. This reminder will come first as HIPAA is reviewed and the implications of this Act for nurses is discussed. The reminder will also come as challenges to maintaining privacy and strategies for promoting privacy are presented.
Notes on the Tension Between Privacy and Surveillance in Nursing
Authors: Johnson Martin
Published: March 2022

Given their 24 hour responsibility for care in many settings, nurses are the main arbiters of the privacy afforded or denied to patients. In this article the author delineates four aspects of privacy, namely: bodily privacy, space privacy, information privacy, and privacy of individual behaviour. He draws on a range of recent evidence that points to people's experiences of health care being unsatisfactory in terms of privacy, and offers explanations as to why much patient privacy is impossible. He argues that the patients’ need for privacy is to a large extent in competition with the professional need for surveillance, noting that while nurses and others do maintain some patient expectations of privacy, these expectations are artificially low on the part of nurses, who are predisposed to invade privacy as an unconscious aspect of their maintenance of professional power. The author provides a discussion of the theoretical basis of this viewpoint, drawing on important insights from Foucault and Goffman, and concludes that an awareness of these issues can help to re-balance the tension between the need for privacy and the need for surveillance.
Perspectives on Suicide Prevention among American Indian and Alaska Native Children and Adolescents: A Call for Help
Authors: Gary Faye , Baker Martha , Grandbois Donna
Published: March 2022

Suicide rates among American Indian Alaska Native (AIAN) children and adolescents are the highest in the United States. Risk factors for suicide among AIAN youth include: strained interpersonal relationships, family instability, depression, low self-esteem, and alcohol use or substance abuse. Protective factors include: caring family relationships, supportive tribal leaders, and positive school experiences. Carefully planned, culturally sensitive, comprehensive programs that address the social determinants of health outcomes such as poverty, school failure, familial conflicts, and limited access to health care, should be the focus of blueprints for change for these vulnerable children. Moreover, culturally competent providers are key elements associated with reducing the suicide rates among AIAN children and adolescents.
Regard normativiste sur l'indépendance du juge
Authors: Regis Nicolas
Published: March 2022

L'article s'efforce de définir l'indépendance du juge selon une double contrainte de cohérence et de parcimonie dans la description d'une structure normative. L'indépendance peut en ce sens être définie comme l'interdiction d'adresser au juge des instructions individuelles dans l'exercice de sa compétence, ce qui implique l'interdiction de le sanctionner directement ou indirectement du fait de ses décisions. Cette définition, moins ambitieuse que celles que donnent actuellement la doctrine et la jurisprudence, permet néanmoins de comprendre en quoi l'indépendance du juge est une garantie de bonne justice et l'une des conditions de l'État de droit.

Heterogeneous Stefan problem and permafrost models with P0-P0 finite elements and fully implicit monolithic solver
Authors: Bigler Lisa , Peszynska Malgorzata , Vohra Naren
Published: March 2022

We consider heat conduction models with phase change in heterogeneous materials. We are motivated by important applications including heat conduction in permafrost, phase change materials (PCM), and human tissue. We focus on the mathematical and computational challenges associated with the nonlinear and discontinuous character of constitutive relationships related to the presence of free boundaries and material interfaces. We propose a monolithic discretization framework based on lowest order mixed finite elements on rectangular grids well known for its conservative properties. We implement this scheme which we call P0-P0 as cell centered finite differences, and combine with a fully implicit time stepping scheme. We show that our algorithm is robust and compares well to piecewise linear approaches. While various basic theoretical properties of the algorithms are well known, we prove several results for the new heterogeneous framework, and point out challenges and open questions; these include the approximability of fluxes by piecewise continuous linears, while the true flux features a jump. We simulate a variety of scenarios of interest.
Eventos agroalimentarios y de productos típicos: instrumentos de promoción para un territorio del sur de Italia
Authors: Di Gregorio Donatella , Guida Arturo , Laganà Valentina Rosa , Cannavò Serafino , Nicolosi Agata
Published: March 2022

Para la mayor parte de las zonas serranas, montañosas y del interior, los productos agroalimentarios locales y típicos representan una importante herramienta para generar ingresos, garantizar la seguridad alimentaria y nutricional, dando respuesta a las necesidades humanas básicas y al deseo de mejorar la calidad de vida. La supervivencia de estas áreas está fuertemente ligada a la persistencia de estos productos, que, además de tener que ser rentables para las comunidades que los producen y que viven de ellos, también deben imponerse en el marco de la competitividad que imponen los mercados. De hecho, sucede que, para muchos de ellos, si bien las condiciones de producción garantizan la calidad y la seguridad alimentaria, no se puede decir lo mismo de su capacidad para competir con la mayoría de las producciones semi-industriales. Gracias a una encuesta a los consumidores, este estudio propone una evaluación de las relaciones entre los eventos / manifestaciones gastronómicas y vinícolas de un área de interior del sur de Italia y algunos productos alimenticios locales que se ofrecen en los puestos de comida con motivo de tales eventos. Desde el punto de vista metodológico, se optó por aplicar el “Análisis de Redes Sociales” (ARS), comparando los eventos gastronómicos, folclóricos y culturales que se detectaron en la zona y con algunos productos alimenticios locales presentes en los puestos. El área considerada es muy interesante en cuanto a los productos típicos y tradicionales, entre los que la trufa es la menos conocida y extendida, y sólo ha comenzado a consolidarse recientemente. Los resultados mostraron que algunos de los productos tomados en consideración son recurrentes, es decir, siempre presentes en los diversos eventos de la zona, otros menos. Los datos muestran el atractivo que estos eventos y jornadas gastronómicas son capaces de suscitar en los consumidores y el interés y propensión a comprar los alimentos de tradición local. En particular, los turistas buscan la experiencia de la gastronomía local y la cultura e identidad del destino visitado. El análisis de estos datos proporciona información sobre la fuerza competitiva que pueden suscitar los eventos enogastronómicos y las producciones locales. Eventos y manifestaciones como los destacados en el trabajo ayudan a preservar la identidad y la autenticidad de las tradiciones locales.
Un sentiment en action
Authors: Luca Fruci Gian
Published: March 2022

La notion de fraternité en 1848 dans la péninsule italienne est non seulement énigmatique, ambiguë, fluide, fuyante et polymorphe, mais elle se caractérise particulièrement par sa valeur opérative en se plaçant comme un vecteur (émotionnel) de rassemblement et un facteur (pré) politique de mobilisation. Avant d’être un principe politique ou une vertu civique, la fraternité du long 1848 italien se présente comme un sentiment en action qui domine aussi bien les élans et rituels pacifiques d’identification nationale patriotique que leur déclinaison – envisagée ou réelle – guerrière. Un sentiment en action typique de la « nouvelle politique » mais que l’on peut rapporter aussi bien à l’imaginaire médiéval (isant) et catholique qu’à l’expérience de la Révolution française et du triennio républicain italien 1796-1799. Ce sentiment représente donc efficacement les caractères ascriptifs et généalogique-parentaux du canon national patriotique du Risorgimento et, d’une manière plus générale, du discours nationaliste du long XIXe siècle européen.
« Più amico che fratello »
Authors: Riall Lucy
Published: March 2022

Au cours du Risorgimento, la famille a représenté une base importante pour l’appartenance politique à la gauche ou à la droite, tout à la fois en termes pratiques et symboliques. Elle était une source de soutien matériel et de réconfort émotionnel, et une image forte d’appartenance politique et/ ou religieuse. À cet égard, les frontières entre public et privé devinrent alors (ou demeurèrent) floues. À travers la vie de Roberto, Prospero et Massimo d’Azeglio, l’article étudie le modèle de la fraternité en tant que forme de politique démocratique. L’étude de la relation entre les trois frères témoigne qu’il est important de considérer les symboles génériques de l’appartenance nationale, comme la famille et le lien fraternel, avec leur impact et leur réception individuels. Elle témoigne, en outre, de l’existence d’un espace privé restreint qui a pu constituer un refuge intime contre la rudesse de la vie publique, mais qui suggère aussi que cette sphère domestique n’était pas exclusivement du domaine des femmes. L’amitié durable entre Prospero et Massimo montre l’importance d’étudier la vie privée des personnages publics : les aspects qui ont été tenus cachés au grand public sont, pour les historiens, souvent plus éclairants que les éléments de leur vie privée utilisés pour atteindre leurs objectifs politiques.
Des frères aux fils, des sœurs au mères
Authors: Bertilotti Teresa
Published: March 2022

En s’appuyant sur une multitude de sources (lettres, affiches, opuscules, monuments, plaques commémoratives etc.) l’article examine le large recours au terme de fraternité fait durant la période de mobilisation et du conflit, semblant mettre au second plan des hiérarchies, celle militaire par exemple. Il analyse ensuite sa transformation avec le passage des « frères » aux « fils » et la redéfinition du rôle des autres figures parentales, dès 1918, pour enfin s’arrêter sur les commémorations et la construction de la mémoire. La solidarité née de l’expérience des tranchées se transforme alors en camaraderie tandis qu’aux femmes, exclues, ne reste que le rôle de veuves ou mères de victimes.
Tra lealtà alla Corona e fedeltà a Roma : I cardinali degli Stati sabaudi dalla Restaurazione alla fine del XIX secolo
Authors: Cozzo Paolo , Merlotti Andrea
Published: March 2022

Nel corso del XIX secolo il regno di Sardegna visse una evoluzione territoriale : dapprima (1815) con l’acquisizione della Liguria, poi, con la cessione di Nizza e della Savoia alla Francia (1860). Nella composizione del Sacro Collegio tali mutamenti non furono privi di significato. A rappresentare la monarchia sabauda nel collegio cardinalizio a metà Ottocento (periodo segnato da tensioni fra la Santa Sede e il governo subalpino) si vennero a trovare diverse porpore (in particolare quelle dei cardinali liguri) che con casa Savoia avevano vincoli di fedeltà esili e recenti, mentre i cardinali piemontesi, specialmente quelli di estrazione nobiliare, dovettero cercare un equilibrio fra la lealtà ad un papato assediato dal neonato regno d’Italia, ed una dinastia che, per cingere la corona di quel regno, non aveva esitato a porre fine al potere temporale della Chiesa.
Cardinaux étrangers dans le Sacré Collège : présence à Rome et en Curie
Authors: Virot Audrey
Published: March 2022

La présence de cardinaux étrangers au sein du Sacré Collège est attestée depuis le Moyen Âge. Cette situation est entérinée par le concile de Trente qui invite à choisir les cardinaux au sein de toutes les nations, pour représenter l’universalité de l’Église. L’existence de cardinaux étrangers se traduit en matière d’équilibre des nationalités au sein du groupe des cardinaux, mais aussi dans les principales congrégations, pour déterminer à partir de quand les grandes responsabilités en curie sont remises à des cardinaux non italiens. Au-delà de la volonté pontificale, qui reste à déterminer, de favoriser l’expression de l’universalité de l’Église, les puissances séculières œuvrent pour accroître leur influence au sein du collège cardinalice dont la principale mission est de choisir le nouveau pontife.
Quand les cardinaux font de la politique : les relations entre les cardinaux américains et Washington pendant les présidences de Ronald Reagan et George H. W. Bush (1981-1993)
Authors: Gayte Marie
Published: March 2022

De par les spécificités de l’Église catholique aux États-Unis, les cardinaux américains occupent depuis toujours une place singulière sur la scène politique de leur pays, faisant office d’interlocuteurs entre Rome et Washington. De patriotes ardents, ils deviennent dans les années 1970, à l’instar de la hiérarchie dont ils font partie, beaucoup plus critiques à l’égard de leur gouvernement. Cet article a pour but d’étudier le rôle joué par les cardinaux américains dans les stratégies déployées par les présidents Reagan et Bush père dans les années 1980 pour neutraliser cette opposition, tout en cherchant à définir la nature du pouvoir que ces cardinaux peuvent exercer dans l’arène politique.
Gasparri, Merry del Val et le gouvernement de Pie XI
Authors: Levant Marie
Published: March 2022

Rivalités internes et groupes de pression ont toujours traversé la Curie romaine. Dans la première partie du pontificat de Pie XI, une quasi guerre des clans s’incarne dans la rivalité entre deux figures clés : les cardinaux Gasparri, secrétaire d’État, et Merry del Val, secrétaire du Saint-Office. L’antagonisme, nourri par des origines et des personnalités éloignées, repose sur des réseaux curiaux différents, que l’on peut ramener à celui de l’intégrisme et celui du consalvisme. Un conflit aiguisé se dessine donc, qui put fragiliser un temps l’autorité du nouveau pontife. Trois périodes apparaissent : celle du Pie XI débutant, peinant à manœuvrer entre des vents contraires ; celle de l’épreuve de force et de sa résolution, sur un mode autoritaire et institutionnel ; tandis que la fin des années vingt correspond à une forme d’équilibre à la fois doctrinal, politique, et personnel.
Pratiques de collection, restauration et commercialisation des fragments de peinture murale romaine à l’époque moderne et contemporaine
Authors: Burlot Delphine
Published: March 2022

Cet article développe un aspect de l’histoire matérielle des fragments d’enduit peint romains, des premières découvertes à la Renaissance jusqu’à aujourd’hui. Avant le XVIIIe s., les peintures romaines sont rarement collectionnées, pour des raisons esthétiques mais aussi pratiques, les fragments d’enduit étant plus fragiles et plus difficiles à extraire de fouille que les marbres. Si la préférence est d’abord donnée aux peintures représentant des sujets historiques ou mythologiques, les fragments recueillis au XIXe s. présentent des thèmes plus modestes, que l’on n’hésite pas à compléter et à décliner, quitte à recomposer entièrement le décor, à la limite de la falsification. Le XXe s. voit apparaître une fétichisation du fragment et un accroissement de la valeur accordée à sa matérialité par rapport à sa valeur esthétique. Le fragment apparaît comme digne d’être collecté par le simple fait qu’il appartient au passé.
Un mare ancora bizantino? L’Adriatico tra Ravenna e Venezia nell’alto Medioevo
Authors: Gelichi Sauro
Published: March 2022

Questo contributo intende analizzare, utilizzando essenzialmente le fonti archeologiche, i processi insediativi che hanno riguardato la fascia nord Adriatica dopo l’età antica. Punti di riferimento, anche topografici, sono Ravenna, capitale dell’Impero romano e poi dell’esarcato (da una parte), e Venezia, la nuova città che dominerà l’Adriatico dal secolo XI in avanti (dall’altra).Questo processo verrà analizzato soprattutto dal punto di vista dei nuovi insediamenti; e le aree prese in considerazione sono nello specifico due, la laguna di Comacchio (a sud del Po) e quella di Venezia. Queste due lagune (ancora formalmente bizantine) sembrano interessate, tra Tarda Antichità ed Alto Medioevo, da processi evolutivi molto simili. Esse rappresentano, inoltre, le aree più dinamiche (sul piano sociale ed economico) tra VII e IX secolo di tutto il nord Italia.Il primo aspetto di analogia è costituito dal fatto che ambedue questi territori sono privi di città nel mondo antico. Il secondo aspetto è che gli insediamenti nuovi che si sviluppano, lo fanno all’interno di un ambiente di carattere pienamente lagunare (Comacchio e Venezia delle origini sono abbastanza simili). Il terzo aspetto è che le comunità che danno vita a questi insediamenti sembrano muoversi in maniera abbastanza autonoma rispetto ai poteri centrali. L’ultimo aspetto di analogia è rappresentato dalla particolare vocazione mercantile che le aristocrazie di ambedue questi centri esprimono.I tempi di sviluppo di questi centri sono invece leggermente differenti e rispondono a logiche politico-economiche diverse. Comacchio, funzionale ad un sistema economico imperniato sull’asse padano, si sviluppa principalmente tra l’ultimo quarto del secolo VII e la fine dell’VIII; mentre Venezia, invece, più legata agli interessi dei Franchi, a partire proprio dagli inizi del IX secolo.
Les diplômes du dīwān sicilien et le passé byzantin de la Sicile
Authors: Nef Annliese
Published: March 2022

Cet article envisage la question de l’éventuel héritage byzantin au sein de la Sicile des XIe-XIIe siècle, non pas d’un point de vue génétique, tant les discontinuités et les réinterprétations constantes d’éléments qui pourraient sembler voisins abondent en Sicile entre le IXe et le XIe siècle, mais d’un point de vue «structurel» . Un point commun des époques byzantine, islamique et normande est le rôle de l’impôt et donc la conception de l’État, toutes choses étant égales par ailleurs. De ce point de vue, un certain nombre d’évolutions affectant notamment le monde rural sicilien peuvent être mieux comprises en observant non seulement ce que nous savons des pays du dār al-Islām, dont la Sicile sort avec la conquête normande, mais aussi ce que nous savons de Byzance. On relira à la lumière de ce comparatisme ce que nous disent les jarā’id-platee et les dafātir al-ḥudūd siciliens de l’organisation des campagnes insulaires.
Mercato della terra e commercio mediterraneo nel versante tirrenico tra X e XI secolo
Authors: Feniello Amedeo
Published: March 2022

A partire dai primi decenni del 900 nel commercio della terra scompaiono i tradizionali strumenti di pagamento, in argento o in solidi di Bisanzio, sostituiti dalla moneta d’oro di provenienza musulmana e siciliana, il tarì. Questa trasformazione è frutto del principale coefficiente dello sviluppo dell’economia rurale: il commercio; la fascia tirrenica si trova proiettata all’interno del flusso di scambi in «import» ed «export» che animano il Mediterraneo musulmano. Commercio alimentato lungo tutta la costa prevalentemente da operatori di origine amalfitana e che fornisce il più valido aiuto all’agricoltura locale. Insomma, la chiave della fortuna del mondo rurale tirrenico sta tutta nell’inserimento delle città meridionali in uno spazio economico mediterraneo prevalentemente musulmano.

Understanding the E-Banking Channel Selection Behavior of Elderly Customers
Authors: Cui Xiaolei , Xu Jianzhong
Published: March 2022

To reveal the influence mechanism of e-banking channel selection of elderly customers, according to the analysis of elderly customers’decision-making process, a threshold model is proposed by using small world customer relationship network and variable setting in this study. The multi-agent simulation of e-banking channel selection behavior of elderly customers is carried out from the perspectives of channel diffusion speed and customer channel selection proportion in the context of Covid-19 pandemic. The research shows that channel performance and individual differences of customers affect the adoption of e-banking by elderly customers. This study also has found that network size and network density can regulate the impact of channel performance on the selection behavior of elderly groups. However, they could play a regulatory role under certain conditions. Finally, this study puts forward some suggestions to improve the channel diffusion efficiency, such as building an elderly friendly e-financial service channel and construction of elderly business market culture.
Predicting User Satisfaction of Mobile Healthcare Services Using Machine Learning
Authors: Lee Haein , Lee Seon Hong , Nan Dongyan , Kim Jang Hyun
Published: March 2022

The outbreak of COVID-19 led to rapid development of the mobile healthcare services. Given that user satisfaction is of great significance in inducing marketing success in competition markets, this research explores and predicts user satisfaction with mobile healthcare services. Specifically, the current research aimed to design a machine learning model that predicts user satisfaction with healthcare services using big data from Google Play Store reviews and satisfaction ratings. By dealing with the sentimental features in online reviews with five classifiers, the authors find that logistic regression with term frequency-inverse document frequency (TF-IDF) and XGBoost with bag of words (BoW) have superior performances in predicting user satisfaction for healthcare services. Based on these results, the authors conclude that such user-generated texts as online reviews can be used to predict user satisfaction, and logistic regression with TF-IDF and XGBoost with BoW can be prioritized for developing online review analysis platforms for healthcare service providers.
18 Months Computed Tomography Follow-Up after Covid-19 Interstitial Pneumonia
Authors: Barini Michela , Percivale Ilaria , Danna Pietro S.C. , Longo Vittorio , Costantini Pietro , Paladini Andrea , Airoldi Chiara , Bellan Mattia , Saba Luca , Carriero Alessandro
Published: March 2022

Background

Our aim is to evaluate the possible persistence of lung parenchyma alterations, in patients who have recovered from Covid-19.

Design and methods

We enrolled a cohort of 115 patients affected by Covid-19, who performed a chest CT scan in the Emergency Department and a chest CT 18 months after hospital discharge. We performed a comparison between chest CT scan 18 months after discharge and spirometric data of patients enrolled. We obtained quantitative scores related to well-aerated parenchyma, interstitial lung disease and parenchymal consolidation. A radiologist recorded the characteristics indicated by the Fleischner Society and “fibrotic like” changes, expressed through a CT severity score ranging from 0 (no involvement) to 25 (maximum involvement).

Results

115 patients (78 men, 37 women; mean age 60.15 years old ±12.52). On quantitative analysis, after 18 months, the volume of normal ventilated parenchyma was significantly increased (16.34 points on average ±14.54, p<0.0001). Groundglass opacities and consolidation values tend to decrease (-9.80 and -6.67 points, p<0.0001). On semiquantitative analysis, pneumonia extension, reactive lymph nodes and crazy paving reached statistical significance (p<0.0001). The severity score decreased by 2.77 points on average (SD 4.96; p<0.0001). There were not statistically significant changes on “fibrotic-like” changes correlated with level of treatment and there was not a statistically significant correlation between CT lung score and spirometric results obtained 18 months after discharge.

Conclusions

Patients recovered from Covid-19 seem to have an improvement of ventilated parenchyma and “fibrotic-like” alterations. The level of treatment does not appear to influence fibrotic changes.
Breast Cancer and Communication: Monocentric Experience of a Self-Assessment Questionnaire
Authors: Longo Vittorio , Abruzzese Flavia , Miserocchi Vittoria , Carriero Serena , Gambaro Anna Clelia , Saba Luca , Carriero Alessandro
Published: March 2022

Background

The communication of the diagnosis of breast cancer induces to the patient a strong psychological trauma. Radiologists are at the forefront of communicating, either for a biopsy or the probable diagnosis of malignancy. This is a complex task, which requires the knowledge and application of correct “communicative models”, among which the SPIKES protocol represents a fundamental reference.

Design and methods

110 patients, with a history of breast cancer, filled out a questionnaire consisting of six questions: five aimed at defining communication compliance with the SPIKES protocol, the sixth, consisting of six feelings, aimed at the knowledge of the next emotional state.

Results

Regarding compliance with various “strategic points” of the SPIKES protocol, questionnaires show that 70% of patients reported no omissions, while the remaining 30% reported omissions relatively to perception (56%), emotions (23%), setting (13%), knowledge (6%) and invitation (2%). The results showed the existence of a correlation between the final emotional state and the correct application of the SPIKES protocol; in fact, patients who reacted with a positive final emotional state-reported greater adherence to the strategic points of the SPIKES protocol.

Conclusions

In healthcare, knowing the communicative compliance of a team in giving “bad news” is fundamental, especially in breast cancer. The SPIKES protocol is recognized by the Literature as a fundamental reference able to affect “positively” the emotional state of patients. The proposed questionnaire is a valid tool to identify the weak points of communication and related criticalities, to improve clinical practice.

Acute scrotal pain (ASP) requiring surgical exploration is common in the pediatric population, but little has been reported on this subject with regard to the adult population. The aim of this study was to investigate the demographic and clinical characteristics and outcomes of scrotal explorations performed on adult patients. Patients over 21 years of age who underwent surgical exploration for ASP with suspected testicular torsion (TT) at 14 French hospitals between January 2005 and December 2019 were included in this study. The main outcome measures were demographic characteristics, pathology found during scrotal exploration, and perioperative outcomes. Logistic regression was used to perform univariate and multivariate analyses to identify predictors of TT. Data for 1329 men were analyzed. The median age was 30 (interquartile range [IQR]: 25–35; range: 21–89) years. Regarding the clinical examination, 867 (65.2%) patients presented with an elevation of the testicle, 613 (46.1%) patients with scrotal edema or erythema, and 211 (15.9%) patients with nausea or vomiting. Operative findings identified TT in only 684 (51.5%) patients, epididymo-orchitis in 112 (8.4%) patients, a tumor in 16 (1.2%) patients, and no causes in 475 (35.7%) patients. Orchiectomy for nonviable testes was required in 101 (7.6%) patients. In multivariate analysis, an elevation of the testicle, erythema/swelling, and the presence of nausea/vomiting were found to be associated with the occurrence of TT. Testicular torsion is not exclusive to children and adolescents, so must be considered in males of any age with acute scrotal findings. However, one-third of scrotal explorations in adults did not lead to a diagnosis.
Comparative Evaluation of Autogenous Bone Graft and Autologous Platelet-Rich Fibrin with and Without 1.2 mg in situ Rosuvastatin Gel in the Surgical Treatment of Intrabony Defect in Chronic Periodontitis Patients
Authors: Gautam Kompal , Kapoor Anjali , Mathur Setu , Ali A. Rizwan , Choudhary Aparna , Shekhawat Arpana
Published: March 2022

Context:

Rosuvastatin (RSV) is a new synthetic, hydrophilic statin with potent anti-inflammatory and osseodifferentiation actions. Autogenous bone graft (ABG) is still considered the gold standard in reconstructive bone surgery. Addition of platelet-rich fibrin (PRF) to ABG provides sustained release of various growth factors and facilitates survival of the graft.

Aims:

The study aims to clinically and radiographically compare the effectiveness of ABG and PRF with and without 1.2 mg RSV gel in the surgical treatment of intrabony defect in chronic Periodontitis patient.

Settings and Design:

This was a randomized controlled clinical trial.

Subjects and Methods:

Thirty-nine patients (one site per participant) with chronic periodontitis were randomly divided into three groups: Group 1 (open flap debridement [OFD] + placebo), Group 2 (OFD + ABG + PRF), and Group 3 (OFD + ABG + PRF + 1.2 mg RSV). Relative attachment level (RAL) and probing pocket depth (PPD) were recorded at baseline, 3, 6, and 9 months. Radiographic measurements such as defect height (A and B) and defect width (C) were calculated at baseline and 9 months.

Statistical Analysis Used:

Intergroup comparison was done using Kruskal–Wallis ANOVA. An intragroup comparison was done using Friedman test and Wilcoxon signed-rank test.

Results:

The mean PPD reduction and mean RAL gain were highly significant in Group 3 and Group 2 than Group 1. For Group 3, a significant reduction of defect height and width and a significant amount of bone fill were achieved than Group 2 and Group 1.

Conclusions:

Addition of 1.2 mg RSV gel, PRF, and ABG has synergistic effects, explaining their role as a regenerative material in the treatment of intrabony defects.
Impact of the COVID-19 pandemic on patients with cancer and cancer survivors
Authors: Shrivastava Saurabh RamBihariLal , Shrivastava Prateek Saurabh
Published: March 2022

The coronavirus disease-2019 (COVID-19) pandemic has impacted the healthcare system. Patients with cancer have been severely affected by the pandemic and have not been able to utilize the required healthcare services in a timely manner. This review is aimed at assessing the clinical and psychological impact of the COVID-19 pandemic on patients with cancer and cancer survivors. A comprehensive literature search was performed for this review in the PubMed database and Google Scholar database using the keywords, “COVID-19,” “cancer,” and “impact” in the title. Of a total of 30 relevant studies, 27 articles were included in the review. In addition, the World Health Organization website was extensively searched for relevant information. For patients with cancer who are affected by COVID-19, it has been advocated that post recovery from COVID-19, the therapeutic management of cancer should resume at the earliest to minimize cancer-related mortality. The COVID-19 pandemic has caused massive disruptions in the prevention, screening, diagnosis, and management of cancer. Therefore, minimizing the effect of the COVID-19 infection and improving the healthcare services offered to the patients with cancer by strengthening the healthcare system is the need of the hour.
COVID-19 vaccination status in Indian patients with cancer
Authors: Batra Ullas , Nathany Shrinidhi , Bansal Nitin , Sharma Mansi
Published: March 2022

Background:

Patients with cancer are at an increased risk of severe coronavirus disease-2019 (COVID-19). Hence, safe and efficacious vaccination against COVID-19 may play a crucial role in conferring protection to this group of patients.

Objectives:

As there are no dedicated trials testing the safety and efficacy of COVID-19 vaccines in immunocompromised individuals or patients with cancer, we conducted this study to assess the vaccination status of Indian patients with cancer.

Materials and Methods:

This single-center observational study was conducted in the Department of Medical Oncology at the Rajiv Gandhi Cancer Institute and Research Centre, Delhi, India, between March and June 2021. Patients with cancer were interviewed telephonically to obtain information related to their vaccination status. The primary endpoint was the proportion of patients with cancer who received a COVID-19 vaccine. The Chi-squared test and McNemar's test were used to determine the associations between the different variables and the vaccination status.

Results:

Of the 752 patients included in the study, 219 (29.1%) had received at least one dose of the COVID-19 vaccine. Of these, 34 (15.5%) patients subsequently developed COVID-19. They were treated in domiciliary care and did not require hospitalization. Of the 533 patients (70.9%) who were not vaccinated, 117 (21.9%) tested positive for COVID-19 and 14 (11.9%) succumbed to the disease.

Conclusion:

Our study suggests that there is probably a lack of awareness or fear related to vaccination, which should be addressed to avoid COVID-19-related cancer mortality.
Vocal fold leukoplakia – An underestimated premalignant lesion of the larynx
Authors: Swain Santosh Kumar , Kar Dattatreya
Published: March 2022

Vocal fold leukoplakia is the clinical term for a whitish patch on the vocal fold mucosa. It is caused by prolonged tobacco smoking, consumption of alcohol, and excessive drying or vocal abuse. Histopathologically, it displays varying degrees of dysplasia and hyperkeratosis. The presence of dysplastic cells in the vocal fold leukoplakia denotes a premalignant lesion. The common clinical presentations of vocal fold leukoplakia include hoarseness of voice, foreign-body sensation, and irritation in the throat. The prognosis of this lesion is uncertain, and it can vary from a non-dysplastic leukoplakia to a squamous cell carcinoma. Early diagnosis and treatment of vocal fold leukoplakia are often challenging, and its management includes excision of the lesion, close follow-up, and avoiding exposure to risk factors such as tobacco smoking and alcohol consumption. For this review, we identified 134 articles from the Scopus, PubMed, Cochrane, and Medline databases and Google Scholar using the search terms, “vocal fold leukoplakia,” “premalignant diseases of the larynx,” “laryngeal keratosis,” “vocal cord leukoplakia,” “glottis,” and “precancerous lesions of glottis.” A total of 52 articles were included in the review. We aimed to assess the epidemiology, etiopathology, clinical presentation, diagnosis, and the current treatment options of vocal fold leukoplakia.

Authors: Padmanabhan Maya , Balasubramanian Satheesan , Muhammed Sha E. K. , Malodan Riyas
Published: March 2022

Background:

Despite the advances in the field of oncology, the diagnosis of cancer is often considered a death sentence, owing to the misconceptions and myths about cancer treatment. Moreover, improvements in health literacy and awareness about cancer have also not been able to change the attitude of people toward cancer-related health behaviors.

Objective:

In this study, we aimed to evaluate the knowledge, perception, and attitude of the general population toward cancer and cancer care.

Materials and Methods:

This cross-sectional study was conducted at Malabar Cancer Center, a tertiary cancer center in Kerala, India, between June 2017 and February 2018. A survey was conducted in the general population in the northern part of Kerala in the districts of Kannur, Kasargod, and Wayanad during a medical camp. People who were aged above 18 years and could read the Malayalam language were included in the study. The participants were administered a questionnaire comprising 26 questions, and the knowledge, perception, and attitude of the general population toward cancer and cancer care were evaluated.

Results:

A total of 487 people responded to the survey. Of these, 354 (72.7%) were women and 133 (27.3%) were men. The mean age of the cohort was 43.7 years. About 74% of the participants disagreed that all cancers can be treated using the same treatment modalities. A total of 84% of the participants agreed that cancer can be detected early with screening. Almost 95% of the participants were aware of the importance of cancer screening and strongly recommended establishing cancer screening clinics in government setups.

Conclusion:

There is a positive attitude among the general public toward cancer. Almost all the people surveyed were interested in attending cancer awareness programs, believed in the role of screening and felt that establishing cancer screening programs would be useful. This may help provide a road map for cancer policy-makers.
