Europa después de la Paz de Westfalia

Europa després de la Pau de Westfalia L'autor examina la situació d'Europa després de 1648 partint del Tractat de Pau de Westfalia. Comença per recordar breument la fortuna històrica d'aquesta "célèbre paix"- en paraules de Voltaire- i després estudia en quina mesura està justificada la valoració favorable de la que aquesta pau s'ha beneficiat. L´'Europa transformada, que ha sorgit de Westfalia, devia la seva transformació al tractat de pau o bé a les dures proves que havia patit durant la guerra a la que aquest acord havia posat fi? Aquestes dures experiències van arribar al seu paroxisme amb els trastorns polítics i socials del decenni de 1640, els quals podrien haver fet néixer una nova necessitat d'estabilitat, com semblen testimoniar-ho en nombrosos països la consolidació i el reforçament del poder reial. Quina incidència va tenir aquest reforçament del poder reial sobre la cultura en la cort de França i en la de l'Imperi? Va conèixer l'Europa posterior a 1648 una accentuació de la separació entre les societats catòliques i pro testants en el moment que s'estava formant una nova república europea de les Lle tres, fonamentada sobre un renovat entusiasme per la ciència i la raó?Europe after the Peace of Westphalia The author studies Europe after 1648 under the light of the Treaty of Westpha lia. He begins by remembering the historical fortune of this célèbre paix, in Voltai re's words, and then considers how much the common favourable judgement on this peace is justified. If the Europe that emerged from this treaty was really a transfor med Europe, was its transformation due to the treaty or rather to the strains that Euro pe experienced through the war finished by the agreement? These strains, which rea ched their paroxysm with the upheavals of the 1640s, could make grow a new need of stability - as the consolidation and strengthening of royal power seem to suggest in many countries. Which was the impact of the strengthening of royal power on the culture of the French and Imperial courts? Did Europe know after 1648 an accen tuation of the division between Catholic and Protestant societies, just when a new European Republic of Letters was forming on a renewed enthusiasm for science and reason?-

Temple versus Household in Luke-Acts: A contrast in social institutions

This social-scientific study of Luke-Acts advances the thesis that in the Lucan economy of salvation, the Temple and the Household represent opposed types of social institutions and economic relations, only one of which, the Household, is capable of embodying socially, symbohcally and ideologically the structures, values and goals of an inclusive gospel of universal salvation

The product of a Petrine circle? A reassessment of the origin and character of 1 Peter

© 2002 SAGE PublicationsRecent studies of 1 Peter, especially by John Elliott, have sought to rescue the letter from its assimilation to the Pauline tradition and to establish the view, now widely held, that 1 Peter is the distinctive product of a Petrine circle. After examining the traditions in 1 Peter, both Pauline and non-Pauline, and the names in the letter (Silvanus, Mark and Peter), this essay argues that there is no substantial evidence, either inside or outside the letter, to support the view of 1 Peter as originating from a specifically Petrine group. It is much more plausibly seen as reflecting the consolidation of early Christian traditions in Roman Christianity. Despite the scholarly majority currently in its favour, the view of 1 Peter as the distinctive product of a Petrine tradition from a Petrine circle should therefore be rejected

Multidimensional collaboration; reflections on action research in a clinical context

This paper reflects on the challenges and benefits of multidimensional collaboration in an action research study to evaluate and improve preoperative education for patients awaiting colorectal surgery. Three cycles of planning, acting,observing and reflecting were designed to evaluate practice and implement change in this interactive setting, calling for specific and distinct collaborations. Data collection includes: observing educational interactions; administering patient evaluation questionnaires; interviewing healthcare staff, patients and carers; patient and carer focus groups; and examining written and audiovisual educational materials. The study revolves around and depends on multi-dimensional collaborations. Reflecting on these collaborations highlights the diversity of perspectives held by all those engaged in the study and enhances the action research lessons. Successfully maintaining the collaborations recognises the need for negotiation, inclusivity, comprehension, brokerage,and problem-solving. Managing the potential tensions is crucial to the successful implementation of changes introduced to practice and thus has important implications for patients’ well-being. This paper describes the experiences from an action research project involving new and specific collaborations, focusing on a particular healthcare setting. It exemplifies the challenges of the collaborative action research process and examines how both researchers and practitioners might reflect on the translation of theory into educational practices within a hospital colorectal department. Despite its context-specific features, the reflections on the types of challenges faced and lessons learned provide implications for action researchers in diverse healthcare settings across the world

Lines, Circles, Planes and Spheres

Let $S$ be a set of $n$ points in $\mathbb{R}^3$, no three collinear and not all coplanar. If at most $n-k$ are coplanar and $n$ is sufficiently large, the total number of planes determined is at least $1 + k \binom{n-k}{2}-\binom{k}{2}(\frac{n-k}{2})$. For similar conditions and sufficiently large $n$, (inspired by the work of P. D. T. A. Elliott in \cite{Ell67}) we also show that the number of spheres determined by $n$ points is at least $1+\binom{n-1}{3}-t_3^{orchard}(n-1)$, and this bound is best possible under its hypothesis. (By $t_3^{orchard}(n)$, we are denoting the maximum number of three-point lines attainable by a configuration of $n$ points, no four collinear, in the plane, i.e., the classic Orchard Problem.) New lower bounds are also given for both lines and circles.Comment: 37 page

Charged Higgs boson in the next-to-minimal supersymmetric standard model with explicit CP violation

The phenomenology of the explicit CP violation in the Higgs sector of the next-to-minimal supersymmetric standard model (NMSSM) is investigated, with emphasis on the charged Higgs boson. The radiative corrections due to both quarks and scalar-quarks of the third generation are taken into account, and the negative result of the search for the Higgs bosons at CERN LEP2, with the discovery limit of 0.1 pb, is imposed as a constraint. It is found that there are parameter regions of the NMSSM where the lightest neutral Higgs boson may even be massless, without being detected at LEP2. This implies that the LEP2 data do not contradict the existence of a massless neutral Higgs boson in the NMSSM. For the charged Higgs boson, the radiative corrections to its mass may be negative in some parameter regions of the NMSSM. The phenomenological lower bound on the radiatively corrected mass of the charged Higgs boson is increased as the CP violation becomes maximal, i.e., as the CP violating phase becomes $\pi/2$. At the maximal CP violation, its lower bound is about 110 GeV for 5 $\leqslant \tan \beta \leqslant$ 40. The vacuum expectation value (VEV) of the neutral Higgs singlet is shown to be no smaller than 16 GeV for any parameter values of the NMSSM with explicit CP violation. This value of the lower limit is found to increase up to about 45 GeV as the ratio ($\tan \beta$) of the VEVs of the two Higgs doublets decreases to smaller values ($\sim$ 2). The discovery limit of the Higgs boson search at LEP2 is found to cover about a half of the kinematically allowed part of the whole parameter space of the NMSSM, and the portion is roughly stable against the CP violating phase.Comment: Latex, 24 pages, 6 figure

Clouds, shadows, or twilight? Mayfly nymphs recognise the difference

1. We examined the relative changes in light intensity that initiate night-time locomotor activity changes in nymphs of the mayfly, Stenonema modestum (Heptageniidae). Tests were carried out in a laboratory stream to examine the hypothesis that nymphs increase their locomotion in response to the large and sustained reductions in relative light intensity that take place during twilight but not to short-term daytime light fluctuations or a minimum light intensity threshold. Ambient light intensity was reduced over a range of values representative of evening twilight. Light was reduced over the same range of intensities either continuously or in discrete intervals while at the same time nymph activity on unglazed tile substrata was video recorded. 2. Nymphs increased their locomotor activity during darkness in response to large, sustained relative light decreases, but not in response to short-term, interrupted periods of light decrease. Nymphs did not recognise darkness unless an adequate light stimulus, such as large and sustained relative decrease in light intensity, had taken place. 3. We show that nymphs perceive light change over time and respond only after a lengthy period of accumulation of light stimulus. The response is much lengthier than reported for other aquatic organisms and is highly adaptive to heterogeneous stream environments

Perioperative complications among head and neck surgery patients with COVID-19

Background: Patients undergoing surgery for head and neck cancer (HNC) have potentially high perioperative complication rates. Recent studies indicate that preoperative COVID-19 infection poses increased risk for postoperative complications in other fields. However, to date, there has not been data showing the effect of COVID-19 on complication rates for HNC. Here, a large database was employed to assess if perioperative COVID-19 increased the risk of perioperative complications among those undergoing HNC surgery. Methods: A retrospective investigation was conducted using a multi-institutional research database. Subjects who underwent HNC surgery from January 2020 to September 2022 were identified using the International Classification of Diseases and Current Procedure Terminology codes. Thirty-day surgical and medical complications were assessed for those diagnosed with COVID-19 infection from 7 days before or after surgery compared to those who were COVID-19 negative. Cohorts were propensity scores matched by age, sex, and race. Results: Perioperative COVID-19 was present in n = 208 and absent in n = 15 158 subjects that underwent HNC surgery. For unmatched analyses, there was a statistically significant increased risk in the 30-day postoperative period in COVID-19-positive patients for the following surgical complications: surgical site fistula, free tissue transfer (FTT) complication, FTT failure, and death. Additionally, there was a statistically significant increased risk in the 30-day postoperative period in COVID-19-positive patients for the following medical complications: ventilator support, pneumonia, vasopressor, acute renal failure, and myocardial infarction. Conclusion: This large, retrospective populational study suggests HNC patients are at increased risk for death and several perioperative complications. This investigation is the first to address this clinical question

Random field sampling for a simplified model of melt-blowing considering turbulent velocity fluctuations

In melt-blowing very thin liquid fiber jets are spun due to high-velocity air streams. In literature there is a clear, unsolved discrepancy between the measured and computed jet attenuation. In this paper we will verify numerically that the turbulent velocity fluctuations causing a random aerodynamic drag on the fiber jets -- that has been neglected so far -- are the crucial effect to close this gap. For this purpose, we model the velocity fluctuations as vector Gaussian random fields on top of a k-epsilon turbulence description and develop an efficient sampling procedure. Taking advantage of the special covariance structure the effort of the sampling is linear in the discretization and makes the realization possible
