This paper is concerned with the estimation of the Weibull generalized exponential distribution parameters based on the adaptive Type-II progressive censored sample. Maximum likelihood estimation, maximum product spacing, and Bayesian estimation based on Markov chain Monte Carlo methods have been determined to find the best estimation method. The Monte Carlo simulation is used to compare the three methods of estimation based on the ATIIP-censored sample, and also, we made a bootstrap confidence interval estimation. We will analyze data related to the (...) distribution about single carbon fiber and electrical data as real data cases to show how the schemes work in practice. (shrink)

Statistical distributions play a prominent role for modeling data in applied fields, particularly in actuarial, financial sciences, and risk management fields. Among the statistical distributions, the heavy-tailed distributions have proven the best choice to use for modeling heavy-tailed financial data. The actuaries are often in search of such types of distributions to provide the best description of the actuarial and financial data. This study presents a new power transformation to introduce a new family of heavy-tailed distributions useful for modeling heavy-tailed (...) financial data. A submodel, namely, heavy-tailed beta-power transformed Weibull model is considered to demonstrate the adequacy of the proposed method. Some actuarial measures such as value at risk, tail value at risk, tail variance, and tail variance premium are calculated. A brief simulation study based on these measures is provided. Finally, an application to the insurance loss dataset is analyzed, which revealed that the proposed distribution is a superior model among the competitors and could potentially be very adequate in describing and modeling actuarial and financial data.

La riche collection d'objets en faïence du musée gréco-romain d'Alexandrie, dont nous préparons la publication complète, comprend plus de mille trois cents pièces découvertes, pour la majeure partie d'entre elles, à Alexandrie ou dans sa région. Nous présentons ici un tableau de la vaisselle ptolémaïque et romaine en insistant plus particulièrement sur les procédés de fabrication et la typologie de ces objets et offrons un état de la question sur la localisation des ateliers et le commerce de cette vaisselle.

Cet article présente, dans une première partie, les fondements éthiques de la gestion de crise qui s’apparentent au pragmatisme et à l’écologie humaniste et s’appliquent dans une approche systémique axée sur l’apprentissage et le dialogue. Dans une deuxième partie, il discute de quelques questions éthiques dans le domaine de la sécurité civile en s’appuyant principalement sur les observations empiriques de l’auteur au Québec. Dans le cadre de sa mission en tant que boursier du Programme canadien de bourses de la Francophonie, (...) l’auteur termine par un examen des défis culturels relatifs à son aspiration d’établir une éthique et une culture de gestion de crise dans son pays, l’Égypte.

L'article constitue la publication du décor peint des deux tombes de la nécropole de Kom el-Chougafa à Alexandrie. Ces deux tombes, creusées dans les parois d'une salle du second hypogée de Kom el-Chougafa, sont connues depuis le début du siècle, mais leur décor peint, en majeure partie effacé, n'a pu être rendu visible que récemment grâce à l'emploi de la lumière dans le spectre ultraviolet. Chaque tombe est constituée d'une niche qui se compose d'un sarcophage, surmonté de trois parois, et (...) d'un plafond. L'ensemble des parties était recouvert d'un enduit peint. La surface des trois parois est divisée en deux registres : le registre supérieur porte des peintures de style égyptien, tandis que le registre inférieur porte des peintures de style grec. Les scènes égyptiennes représentent, de gauche à droite, l'offrande du faucon (promesse d'immortalité), l'embaumement d'Osiris et la résurrection du dieu. Les scènes grecques, quant à elles, représentent, toujours de gauche à droite, Perséphone cueillant des fleurs avec ses compagnes, l'enlève ment de Perséphone, son retour du monde des morts vers celui des vivants. La correspondance des deux séries de scènes superposées est évidente, comme les têtes de Méduse et de Bès sur la partie/supérieure des pilastres. Différente du « style mixte » — personnages de style grec inclus dans une scène égyptienne — qui caractérise certaines représentations funéraires de l'Alexandrie impériale comme du Fayoum, cette combinaison iconographique est unique.

Après une première présentation de la vaisselle en faïence du Musée gréco-romain d'Alexandrie (BCH 117 [1993], p. 565-602), nous étudions ici, à travers une sélection d'objets inédits, la petite plastique en faïence de style et de thèmes grecs ou gréco- égyptiens. Cette dernière offre un bon exemple de l'adaptation d'une technique traditionnelle à un nouveau répertoire iconographique et permet, par l'examen des contextes de découverte, d'apporter une contribution aux études sur les pratiques religieuses dans l'Egypte gréco-romaine.

Este trabajo analiza el lenguaje subjetivo empleado por el intelectual y político andalusí Lisān al-Dīn Ibn al-Ḫaṭīb (m. 1375) en su obra de exilio Nufāḍat al-ǧirāb. El objetivo es explorar la utilidad de un enfoque lingüístico en la comprensión del lugar que ocupa este texto dentro del proceso de transición cultural del Occidente islámico hacia el paradigma moderno europeo. El estudio se divide en tres partes: en la primera, se hace una breve introducción al autor, a su contexto socio-político y (...) al contenido de la obra; en la segunda, se plantea una metodología cuantitativo-cualitativa a través de la cual se estructura el texto misceláneo digitalizado en función de sus géneros y se especifica un esquema de anotación que permite extraer las instancias de los fenómenos lingüísticos más destacados; y en la tercera, se procede al análisis de los datos obtenidos en torno a la acción, la emoción y la evaluación. El análisis muestra una compleja codificación de la subjetividad en la Nufāḍa donde, a diferencia del Taʿrīf de Ibn Ḫaldūn, las marcas de expresión en primera persona, aunque significativas, son escasas. Sin embargo, se identifica un abundante uso de adjetivos evaluativos a lo largo de la obra, con una riqueza léxica que permite revelar de forma explícita el punto de vista del sujeto autor. Este hallazgo demuestra la utilidad de una metodología híbrida en la aproximación a textos histórico-literarios premodernos, así como la necesidad de incorporar el análisis lingüístico, empírico y comparativo al estudio de la transición epistemológica señalada.

The study aimed to investigate the impact of behavioral biases on herding for Islamic financial products with the mediation of shariah literacy. An adopted questionnaire from several published studies was used to collect data. The data were collected from 410 respondents and were analyzed with SmartPLS. The results for the direct impact showed that self-attribution, illusion of control, and information availability have a positive and significant impact on herding for Islamic financial products while shariah literacy showed an insignificant impact on (...) herding. The results for mediation showed that previously significant and positive impact turned to insignificant when shariah literacy was introduced as mediating variable between the illusion of control, self-attribution, information availability, and herding. From a theoretical perspective, this study would contribute to the existing body of knowledge of financial decision making from shariah literacy point-out. On the other hand, the findings of this study may be useful for investors to avoid herding in the Islamic financial markets. The authors synthesize the contribution made by behavioral finance studies in extending the knowledge of herding behavior in Islamic financial products with a mediating role of shariah literacy. The key limitation of the study includes data that were collected from three districts of Punjab, Pakistan. (shrink)

The ternary xV2O5–(40 − x)Li2O–60B2O3 glass system, where x = 1, 2, 3, 4 and 6 mol%, was prepared by normal quenching. Ultrasonic velocities and attenuation were measured at room temperature using a pulse-echo technique. Various parameters, such as elastic moduli, micro-hardness, Poisson's ratio and Debye temperature, were determined from the measured densities and velocities. The composition dependence of these parameters, in addition to the glass-transition temperature, suggested that vanadium ions were incorporated into these glasses as a network modifier, resulting (...) in the reconversion of BO4 tetrahedra to BO3 triangles by the breaking of B–O–B linkages and the formation of nonbridging oxygens (NBOs). The outcome was a reduction in network connectivity and rigidity with increasing V2O5 content. The results are explained quantitatively in terms of fractal bond connectivity, average atomic volume, network dimensionality, packing density, number of network bonds per unit volume, cross-link density and atomic ring size. The Makishima and Mackenzie model appears to be valid for the studied glasses when the fate of BO4 tetrahedra and creation of NBOs are taken into account. (shrink)

Autophagy functions in both selective and non‐selective ways to maintain cellular homeostasis. Endoplasmic reticulum autophagy (ER‐phagy) is a subclass of autophagy responsible for the degradation of the endoplasmic reticulum through selective encapsulation into autophagosomes. ER‐phagy occurs both under physiological conditions and in response to stress cues, and plays a crucial role in maintaining the homeostatic control of the organelle. Although specific receptors that target parts of the ER membrane, as well as, internal proteins for lysosomal degradation have been identified, the (...) molecular regulation of ER‐phagy has been elusive. Recent work has uncovered novel regulators of ER‐phagy that involve post‐translational modifications of ER‐resident proteins and functional cross‐talk with other cellular processes. Herein, we discuss how morphology affects the function of the peripheral ER, and how ER‐phagy modulates the turnover of this organelle. We also address how ER‐phagy is regulated at the molecular level, considering implications relevant to human diseases. (shrink)

This article investigates the impacts of proper modeling of the wake effects and wind speed delays, between different wind turbines' rows, on the dynamic performance accuracy of the wind farms models. Three different modeling scenarios were compared to highlight the impacts of wake effects and wind speed time-delay models. In the first scenario, wind wake effect and time delay are ignored. Consequently, all wind turbines are assumed subjected to the same wind speed profile. The second scenario considers the wind wake (...) effect, and it was modeled by reducing the incident wind speed values by 0.5 m/s from one row to the next row facing the wind. The last scenario, the proposed model, used the wind wake effect model developed for wind turbines micrositting applications and considered the effect of the delay time between the wind speed profiles incident on the different wind turbines' rows.

In this study, some new hypotheses and techniques are presented to obtain some new analytical solutions to the generalized Kawahara equation. As a particular case, some traveling wave solutions to both Kawahara equation and modified Kawahara equation are derived in detail. Periodic and soliton solutions to this family are obtained. The periodic solutions are expressed in terms of Weierstrass elliptic functions and Jacobian elliptic functions. For KE, some direct and indirect approaches are carried out to derive the periodic and localized (...) solutions. For mKE, two different hypotheses in the form of WSEFs are used to derive the periodic and localized solutions. Also, the cnoidal wave solutions in the form of JEFs are obtained. As a realistic physical application, the solutions obtained can be dedicated to studying many nonlinear waves that propagate in plasma. (shrink)

In this paper, some novel analytical and numerical techniques are introduced for solving and analyzing nonlinear second-order ordinary differential equations that are associated to some strongly nonlinear oscillators such as a quadratically damped pendulum equation. Two different analytical approximations are obtained: for the first approximation, the ansatz method with the help of Chebyshev approximate polynomial is employed to derive an approximation in the form of trigonometric functions. For the second analytical approximation, a novel hybrid homotopy with Krylov–Bogoliubov–Mitropolsky method is introduced (...) for the first time for analyzing the evolution equation. For the numerical approximation, both the finite difference method and Galerkin method are presented for analyzing the strong nonlinear quadratically damped pendulum equation that arises in real life, such as nonlinear phenomena in plasma physics, engineering, and so on. Several examples are discussed and compared to the Runge–Kutta numerical approximation to investigate and examine the accuracy of the obtained approximations. Moreover, the accuracy of all obtained approximations is checked by estimating the maximum residual and distance errors. (shrink)

The problem of finding optimal sampling schemes has been resolved in two models. The novelty of this study lies in its cost efficiency, specifically, for the applied problems with expensive sampling process. In discussed models, we show that some observations counteract other ones in prediction mechanism. The autocovariance function of underlying process causes mentioned result. Our interesting result is that, although removing neutralizing observations convert sampling scheme to nonredundant case, it causes to worse prediction. A simulation study confirms this matter, (...) too. (shrink)

A multifaceted, holistic approach to identifying potential predictors is needed to eradicate workplace bullying. The current study investigated the impact of an unfavourable organisational climate that plays a role in breeding workplace bullying. The present study also postulated that individual personality differences mediate between a caring climate and workplace bullying. Similarly, the interaction between workplace bullying and personality impacts PTSD. We also checked the role of workplace bullying as a mediator between a caring climate and PTSD. This research tested all (...) the proposed hypotheses, and the study was conducted in Pakistan. The data is analysed using the two-step partial least square structural equation modelling procedure. The first part assesses the measurement model, while in the second step, the structural model is evaluated. The results supported all the proposed hypotheses of this study. Type A behaviour moderated the caring climate—person-related bullying relationship, whereas it did not moderate the caring climate—work-related bullying in the suggested direction. Type A behaviour is moderated for both types of bullying and PTSD. Results also show significant indirect effects of a caring climate on PTSD through workplace bullying. This study will contribute theoretically to filling the literature gap on studies of climate-bullying and bullying-stress using contingency factors. (shrink)

BackgroundThe nursing profession requires ethical and legal regulations to guide nurses’ performance. Ethical climate plays a part in shaping nurses’ ethical practice. Therefore, ethico-legal aspects and ethical climate contribute to improving nurses’ ethical practice and competencies with reducing medical errors in hospital settings.ObjectiveThis study examined the effect of ethico-legal aspects and ethical climate on managing safe patient care and medical errors among nurses.Materials and methodsA cross-sectional correlational study was carried out on 548 nurses. Data were collected through self-administered questionnaires about (...) nurses’ knowledge in both ethical and legal aspects, ethical practice, competencies, ethical climate and experience with medical error.ResultsThe main sources of nurses’ knowledge of ethical and legal aspects were undergraduate lectures, job experience and colleagues. Nurses’ knowledge in both ethical and legal aspects, nurses’ ethical practice and competencies were insufficient. Nurses fairly perceived their ethical climate. Also, nurses experienced medical errors about 22.6% in their units. Nurses’ knowledge of ethical and legal aspects, as well as the ethical climate were positive predictors of inadequate nurses’ ethical practice and competencies. Additionally, nurses’ knowledge in both ethical and legal aspects, ethical climate and practice had a negative influence on the occurrence of medical errors.ConclusionEnhancing nurses’ knowledge in both ethical and legal aspects as well as ethical climate could significantly influence improving nurses’ ethical practice, competencies and reducing medical errors in the study units. Therefore, planning for enhancing the nurses’ ethico-legal learning and ethical climate seems to be mandatory. (shrink)
