I dubbi sul sacramento del matrimonio e la questione dei matrimoni misti nella casistica delle congregazioni romane (secc. XVI-XVIII)
Authors: Scaramella Pierroberto 
Published: April 2018

All’inizio del XVII secolo a gestire le questioni matrimoniali miste, e a dirimerne i dubia che incessantemente arrivavano da quelle regioni dove, di fatto, convivevano cattolici e protestanti, vennero a trovarsi ben tre Congregazioni, quella del Sant’Ufficio, quella del Concilio e quella De Propaganda Fide. Accanto ad esse, la preminenza giurisdizionale veniva arrogata sovente dal potere vescovile.
Scopo del presente lavoro è quello di seguire l’iter degli atti giurisdizionali attraverso i quali, a partire dai presupposti teologici e dalle decisioni che ne scaturivano, si risolvevano i dubbi che provenivano da regioni dalla politica religiosa incerta per la Chiesa, o sostanzialmente ostile. Si tratta di un punto di osservazione ottimale per comprendere le logiche corali del cattolicesimo postridentino, ma anche le sue incessanti lacerazioni interne, le ricomposizioni, sino all’idea che il giudizio pratico nasca non su presupposti teorici, ma de agendo, utilizzando cioè i principi diplomatici dell’utilità pratica.
La storia dei matrimoni misti è ancora un prolungamento della storia della Riforma protestante e dello scontro con le comunità religiose da essa scaturite. È proprio in materia matrimoniale, segnatamente in quelle regioni a confessione religiosa mista, che si riflettono non soltanto le ansie che scaturivano dal contatto con gli «eretici» e con i loro fautori, ma anche la riflessione teologica e politica sulla realtà non soltanto sacramentale, ma anche contrattuale del matrimonio, ed offre tutto il senso delle unioni cristiane tipico dell’epoca pretridentina.

Abstract
The most robust way for determining the distance of quasar absorption outflows is the use of troughs from ionic excited states. The column density ratio between the excited and resonance states yields the outflow number density. Combined with a knowledge of the outflow’s ionization parameter, a distance from the central source (R) can be determined. Here we report results from two surveys targeting outflows that show troughs from S iv. One survey includes 1091 SDSS and BOSS quasar spectra, and the other includes higher-quality spectra of 13 quasars observed with the Very Large Telescope. Our S iv samples include 38 broad absorption line (BAL) outflows and four mini-BAL outflows. The S iv is formed in the same physical region of the outflow as the canonical outflow-identifying species C iv. Our results show that S iv absorption is only detected in 25% of C iv BAL outflows. The smaller detection fraction is due to the higher total column density (N
H) needed to detect S iv absorption. Since R empirically anticorrelates with N
H, the results of these surveys can be extrapolated to C iv quasar outflows with lower N
H as well. We find that at least 50% of quasar outflows are at distances larger than 100 pc from the central source, and at least 12% are at distances larger than 1000 pc. These results have profound implications for the study of the origin and acceleration mechanism of quasar outflows and their effects on the host galaxy.
Expression of p53 & epidermal growth factor receptor in glioblastoma
Authors: Karnam Sameera , Kottu Radhika , Chowhan Amit Kumar , Bodepati Prasad Chandramouleswara 
Published: April 2018

Background & objectives:
Glioblastoma (GB) is the most frequent brain tumour, manifesting at any age, with a peak incidence between 45 and 75 years. Primary and secondary GBs constitute relatively distinct disease entities in evolution, in expression profiles and in therapeutic response. Histopathologically, primary and secondary GBs are indistinguishable. The aim of this investigation was to study the immunohistochemical (IHC) expression of p53 and epidermal growth factor receptor (EGFR) in GB with the objective of categorizing the morphological variants of GB into primary and secondary based on the presence of low-grade areas and knowing the variable expression of p53 and EGFR in primary and secondary GB.

Methods:
A total of 28 patients with GB were studied and categorized into primary and secondary based on the presence of low-grade areas, i.e. discernible astrocytic morphology, gemistocyte and oligodendroglia. Tumours with the presence of combination of the above features or any one of the above features were taken as secondary GB, whereas tumours with highly pleomorphic areas were considered as primary GB. IHC was done on the representative tissue blocks for p53 and EGFR.

Results:
Majority of the patients were in the fifth and sixth decades of life with a mean age of 46.96±13 yr with male preponderance (male:female 2.5:1). Mean age of presentation was 48.93±12 yr in primary and 44.69±15 yr in secondary GB. All cases of GB were classified into primary (53.57%) and secondary (46.43%) based on morphology. EGFR was more frequently expressed than p53. Based on IHC, 50 per cent of cases were classified into primary, three per cent into secondary and 47 per cent as unclassified.

Interpretation & conclusions:
Histopathological features, i.e. presence of low-grade areas, may play a role in classifying GB into primary and secondary. EGFR has a pivotal role in gliomagenesis. Combination of p53 and EGFR alone may not be sufficient to clarify GB into primary and secondary.

Published: April 2018

Background & objectives:
The snakebites are considered to be an occupational hazard in agriculture workers and the snake handlers, resulting in a considerable morbidity, mortality and economical implications. This study was conducted to determine the incidence, clinical presentation, renal injury and clinical outcome in snakebite victims who developed acute kidney injury (AKI).

Methods:
This hospital-based prospective, observational study was done on 100 cases who were admitted for the management of snakebite and found to develop AKI in a tertiary care hospital at Hyderabad, India. Renal function tests, complete blood picture, urine routine examination, ultrasound examination of abdomen and coagulation profile were done and the prognosis was assessed by noting recovery, mortality, morbidity and/or progress to chronic stage.

Results:
A total of 100 patients with a mean age of 43.80±12.63 yr (range 18-70); 62 males and 38 females were studied. All had bites on lower limbs. A total of 86 patients arrived in the hospital within 24 h, and 14 arrived after 24 h. Oliguria was found in 60, bleeding tendencies in 64, haemodynamic instability noted - tachycardia in 86. Systolic blood pressure (BP) was <120 mm Hg in 68 and BP was not recordable in four patients. Twelve patients were in stage III kidney disease and needed haemodialysis. Of the 100 cases of snakebite-induced acute kidney failure, 86 recovered and six died. On follow up, after six months eight patients developed chronic kidney failure.

Interpretation & conclusions:
A cascade of events tends to occur in severe haemotoxic envenomation such as bleeding disorders, hypotension/circulatory shock, intravascular haemolysis, disseminated intravascular coagulation and acute respiratory disease syndrome (ARDS). The findings of this study showed that early hospitalization, quick antisnake venom administration and adequate supporting care provided promising results.

Published: April 2018

Objective: Nursing services are considered strategic in the functioning of health organizations, therefore the study of intellectual capital (human capital, structural capital, relational capital of nursing services) in innovation as a contribution to decision policies, practice and research. The main focus is to promote critical thinking on the condition of nursing services in an innovative perspective. This study aims to adapt and validate the psychometric properties of the Questionnaire of Intellectual Capital and Innovative Capacity (already used in business management, automobile) and apply it to the Nursing Services (QICICNS).Methods: A cross-sectional and quantitative study was carried out on a sample of 1,388 Portuguese nurses enrolled in the Nurses’ Order. For the analysis of the psychometric properties of the instrument we used the factorial analysis of main components with varimax rotation of the scale items and the calculation of the Cronbach Alpha coefficient.Results: The QICICNS analysis revealed good internal consistency (global scale = 0.95, constructs between 0.83 and 0.97) and good quality of the items (KMO = 0.95), with four factors being extracted: human capital, relational capital, structural capital and innovation.Conclusions: The positive indices of internal consistency and the sensitivity of this questionnaire show the validity of the reliable and robust data collection instrument in the studied context. Implications for nursing management: QICICNS, due to its multifaceted nature, can be a management tool in the decision making support by nursing managers. The characteristics of each intellectual capital construct may influence the management of services and future investigations.
Nursing management and leadership approaches from the perspective of registered nurses in Portugal
Authors: Fernandes Rita , Araújo Beatriz , Pereira Fátima 
Published: April 2018

Background: The leadership role in nursing reflects the complexity and rapid transformations which take place in healthcare. The influences of this catalyst of change are important for nurses’ identity and professional development, as well as for evolving and innovating nursing practices.Objective: This study is part of a larger research project on doctoral Leadership in Nursing, aims to identify nurses’ perceptions regarding their similarities and differences compared to nurses in manager roles, in order to understand and recognise the influences and barriers to leadership in the nursing hierarchy.Methods: A descriptive cross-sectional study of a qualitative nature, involved the participation of 19 registered nurses (RNs), based on the Zavalloni Ego-Ecological Theory.Results: From the dimension of identification emerged two major themes - the vision of the profession and the competency skills required. The major theme of competency skills includes subthemes of relational, technical/scientific, leadership and management competencies. From the dimension of differentiation emerged two major themes - the vision of the profession and the competency skills. The major theme competency skills included two subthemes - the deficit of relational and management competency skills.Conclusions: Nurse-managers may choose to distance or influence nurses; influence can be achieved through not only a combination of leadership and management competencies but also on the nurse-managers’ evidence-based expertise and relational skills alongside a vision to support team unity in order to create a positive environment which encourages the nurses to be involved in high quality and innovative practices.Implications for nursing management: This study may help to understand the approaches undertaken by leaders in nursing and subsequently enhance their performance. It may also inform future leadership training for nurses.

Published: April 2018

Background and objective: Elevated pressure within the cavity of the abdomen is a serious complication that can threat the life of critically ill patients. Thus, there is an intense need to highlight the outcomes of intra-abdominal hypertension (IAH) that can face critical care nurses. This work aimed to explore the deterioration of mechanical ventilated patients in the presence of IAH.Methods: Design: A non-randomized prospective study. Procedures: This trial was implemented in trauma and general intensive care in the period between December 2015 and August 2016. The pressure within the abdomen was measured for each patient, three times with 8-hr interval, at the third day of mechanical ventilator (MV). Sepsis-related organ failure assessment score was measured for all patients at first day of admission. All patients who had normal intra-abdominal pressure (IAP) or developed IAH were observed, monitored and evaluated for the clinical outcomes until discharged. Results: Of the 60 MV patients, 83.3% developed IAH. Higher mean of MV and stay period among patients with increased pressure within the abdomen (14.04 ± 10.30 and 16.30 ± 9.36) than normotensive patients (6.90 ± 2.80 and 11.000 ± 3.77) with significant difference (p = .001). Non-survivor had a significantly higher mean IAP than survivor (23.266 ± 2.37 vs. 7.91 ± 3.17) (p value < .001).Conclusions: The occurrence of IAH complicated 83.3% of mechanical ventilated clients in the study period: like longer stay and use of ventilator, and high mortality rate.
Monetary Seigniorage in an Emerging Economy: Empirical Evidences
Authors: Chakraborty Lekha 
Published: April 2018

It is often emphasised that monetary seigniorage financing of public sector deficits is technically a “free lunch” if the economy has not attained the full employment levels. However, conservative macroeconomic policies in many emerging and developing economies, especially in the last two decades, have moved away from seigniorage financing to debt financing of deficits to give greater autonomy to the central banks. Against this backdrop, the paper analyses the fiscal and monetary policy co-ordination in India by constructing a monetary seigniorage Laffer curve. If such a curve exists, it is possible to derive a seigniorage-maximizing inflation rate to estimate the optimal level of seigniorage financing of deficits. The illustrative estimates from the Indian data using error correction mechanism models confirm the possibility of a monetary seigniorage Laffer curve.
Clark measures and a theorem of Ritt
Authors: Chalendar Isabelle , Gorkin Pamela , Partington Jonathan R. , Ross William T. 
Published: April 2018

We determine when a finite Blaschke product $B$ can be written, in a non-trivial way, as a composition of two finite Blaschke products (Ritt's problem) in terms of the Clark measure for $B$. Our tools involve the numerical range of compressed shift operators and the geometry of certain polygons circumscribing the numerical range of the relevant operator. As a consequence of our results, we can determine, in terms of Clark measures, when two finite Blaschke products commute.
Pencils and nets on curves arising from rank $1$ sheaves on K3 surfaces
Authors: Rasmussen Nils Henry 
Published: April 2018

Let $S$ be a K3 surface, $C$ a smooth curve on $S$ with $\mathcal{O} _S(C)$ ample, and $A$ a base-point free $g^2_d$ on $C$ of small degree. We use Lazarsfeld-Mukai bundles to prove that $A$ is cut out by the global sections of a rank $1$ torsion-free sheaf $\mathcal{G} $ on $S$. Furthermore, we show that $c_1(\mathcal{G} )$ with one exception is adapted to $\mathcal{O} _S(C)$ and satisfies $\operatorname{Cliff} (c_1(\mathcal{G} )_{|C})\leq \operatorname{Cliff} (A)$, thereby confirming a conjecture posed by Donagi and Morrison. We also show that the same methods can be used to give a simple proof of the conjecture in the $g^1_d$ case.In the final section, we give an example of the mentioned exception where $h^0(C,c_1(\mathcal{G} )_{|C})$ is dependent on the curve $C$ in its linear system, thereby failing to be adapted to $\mathcal{O} _S(C)$.
Kernelized relative entropy for direct fault detection in industrial rotary kilns
Authors: Hamadouche Anis , Kouadri Abdelmalek , Bensmail Abderazak 
Published: April 2018

SummaryThe objective of this work is to use a 1‐dimensional signal that reflects the dissimilarity between multidimensional probability densities for detection. With the modified Kullback‐Leibler divergence, faults can be directly detected without any normality assumption or joint monitoring of related test statistics in different subspaces such as theT2andSPEin principal component analysis–based methods. To relieve the difficulty associated with asymptotic high‐dimensional density estimates, we have estimated the density ratio rather than the densities themselves. This can be done by approximating the density ratio with kernel basis functions and learn the weights from the available data. The developed algorithm is generic and can be applied to any industrial system as long as process historical data is available. As a case study, we apply this algorithm to a real rotary kiln in operation, which is an integral part of the cement manufacturing plant of Ain El Kebira, Algeria.
Fault detection and identification for a class of continuous piecewise affine systems with unknown subsystems and partitions
Authors: Moustakis Nikolaos , Zhou Bingyu , Le Quang Thuan , Baldi Simone 
Published: April 2018

SummaryThis paper establishes a novel online fault detection and identification strategy for a class of continuous piecewise affine (PWA) systems, namely, bimodal and trimodal PWA systems. The main contributions with respect to the state‐of‐the‐art are the recursive nature of the proposed scheme and the consideration of parametric uncertainties in both partitions and in subsystems parameters. In order to handle this situation, we recast the continuous PWA into its max‐form representation and we exploit the recursive Newton‐Gauss algorithm on a suitable cost function to derive the adaptive laws to estimate online the unknown subsystem parameters, the partitions, and the loss in control authority for the PWA model. The effectiveness of the proposed methodology is verified via simulations applied to the benchmark example of a wheeled mobile robot.
Robust RBF neural network–based backstepping controller for implantable cardiac pacemakers
Authors: Karar Mohamed Esmail 
Published: April 2018

SummaryImplantable cardiac pacemaker is a standard medical device to treat heart rhythm disorders. In this paper, a new adaptive backstepping controller is developed to enhance the performance of dual‐sensor pacemakers for regulating the heart rate based on radial basis function neural networks. The robust design of adaptive backstepping controller using Lyapunov functions allows to guarantee the stability and performance of the rate‐adaptive pacing system for accurately accomplishing the heart rate regulation at different preset or desired values. The developed control system has been successfully validated using 12 cases of the preset heart rates for 4 patients during 3 body activities, namely, at rest, walking, and jogging. The resulting root mean square error and maximum error are less than 0.9 and 1.7%, respectively. Moreover, the comparative results of this study showed that the performance of developed backstepping controller is superior to other pacemaker controllers in the previous studies. Therefore, it is potentially valid to be applied in dual‐sensor cardiac pacemakers for the clinical use.
Mechanically Robust, Ultraelastic Hierarchical Foam with Tunable Properties via 3D Printing
Authors: Chen Qiyi , Cao Peng‐Fei , Advincula Rigoberto C. 
Published: April 2018

AbstractA mechanically robust, ultraelastic foam with controlled multiscale architectures and tunable mechanical/conductive performance is fabricated via 3D printing. Hierarchical porosity, including both macro‐ and microscaled pores, are produced by the combination of direct ink writing (DIW), acid etching, and phase inversion. The thixotropic inks in DIW are formulated by a simple one‐pot process to disperse duo nanoparticles (nanoclay and silica nanoparticles) in a polyurethane suspension. The resulting lightweight foam exhibits tailorable mechanical strength, unprecedented elasticity (standing over 1000 compression cycles), and remarkable robustness (rapidly and fully recover after a load more than 20 000 times of its own weight). Surface coating of carbon nanotubes yields a conductive elastic foam that can be used as piezoresistivity sensor with high sensitivity. For the first time, this strategy achieves 3D printing of elastic foam with controlled multilevel 3D structures and mechanical/conductive properties. Moreover, the facile ink preparation method can be utilized to fabricate foams of various materials with desirable performance via 3D printing.
Perovskite‐Initiated Photopolymerization for Singly Dispersed Luminescent Nanocomposites
Authors: Wong Ying‐Chieh , De Andrew Ng Jun , Tan Zhi‐Kuang 
Published: April 2018

AbstractMetal halide perovskites have demonstrated rich photophysics and remarkable potential in photovoltaic and electroluminescent devices. However, the photoactivity of perovskite semiconductors in chemical processes remains relatively unexplored. Here, a general approach toward the synthesis of luminescent perovskite–polymer nanocomposites is reported, whereby perovskite nanocrystals are used as photoinitiators in the polymerization of vinyl monomers. The white‐light illumination of a perovskite–monomer mixture triggers a free‐radical chain‐growth polymerization process, giving rise to high molecular weight polymers of ≈200 kDa. The in situ growth of polymer chains from the perovskite crystal surface allows the formation of individually dispersed nanocrystal cores within an encapsulating polymer matrix, and leads to a significant threefold enhancement in photoluminescence quantum yield. This photoluminescence enhancement is attributed to the spatial separation of the perovskite nanocrystals and hence the deactivation of energy transfer to dark crystals. The resulting perovskite–polymer nanocomposites exhibit excellent stability against moisture and are shown to be useful as functional downconversion phosphor films for luminescent displays and lighting.
Care Like Kin: Community Based Youth Serving Organizations and the Social Reproduction of Disconnected Youth in Rural America
Authors: Visser M. Anne 
Published: April 2018

AbstractIncreasing economic insecurity faced by older youth in rural America presents a crisis of social reproduction for disconnected youth in these areas. Increasingly community based youth serving organizations (CBYSOs) are recognizing and responding to the social reproduction needs of this particularly vulnerable youth population. Such responses are often hidden from funders, government agencies, and community residents. Yet these institutions play an important substitution function for disconnected youth and provide critical social support and social leverage for this population. Based on case studies of three CBYSOs in the San Joaquin Valley of California, this article explores how and why CBYSOs play a substitution function for disconnected youth in rural communities. It is the argument of this article that the social reproduction work of CBYSOs is undertaken with a ethic of care that may have the capacity to transform the political, social, and economic contexts that face this marginalized youth population.
