description: For a coherent system the Barlow-Proschan importance index, defined when the component lifetimes are independent, measures the probability that the failure of a given component causes the system to fail. Iyer (1992) extended this concept to the more general case when the component lifetimes are jointly absolutely continuous but not necessarily independent. Assuming only that the joint distribution of component lifetimes has no ties, we give an explicit expression for this extended index in terms of the discrete derivatives of the structure function and provide an interpretation of it as a probabilistic value, a concept introduced in game theory. This enables us to interpret Iyer's formula in this more general setting. We also discuss the analogy between this concept and that of system signature and show how it can be used to define a symmetry index for systems.

description: Ogni sapere è solidale con una rete fitta e intricata di saperi e pratiche nascoste, la cui continuità è tutt'uno con una dimensione di ininterrotto oblio. Il sapere comune è continuamente riattivato e trasferito entro nuovi contesti, dimenticato come tale e rilanciato. La filosofia è una pratica che, insieme, dipende da quello sfondo e riconfigura quello sfondo. Anch'essa si perde di continuo, e anch'essa si salva, di continuo, in figure inedite e luoghi imprevisti, se guardati con gli occhi della sua tradizione e della sua intenzionalità passata.

The Complexity of Linear Tensor Product Problems in (Anti-) Symmetric Hilbert Spaces
Creators: name: Weimar, Markus
Publisher: name: arXiv
Year: 2011
Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: We study linear problems defined on tensor products of Hilbert spaces with an additional (anti-) symmetry property. We construct a linear algorithm that uses finitely many continuous linear functionals and show an explicit formula for its worst case error in terms of the singular values of the univariate problem. Moreover, we show that this algorithm is optimal with respect to a wide class of algorithms and investigate its complexity. We clarify the influence of different (anti-) symmetry conditions on the complexity, compared to the classical unrestricted problem. In particular, for symmetric problems we give characterizations for polynomial tractability and strong polynomial tractability in terms of the amount of the assumed symmetry. Finally, we apply our results to the approximation problem of solutions of the electronic Schrödinger equation.

description: Over a million people sought asylum in Germany between 2014 and 2016. During this time, many Germans began volunteering in various ways to help refugees and mentorship pro- grams in particular gained significance. As this report shows, participating in a mentorship program has a positive impact on refugees: They improve their language skills and become more socially active. Mentors experience the relationship positively and want to continue their volunteer work with refugees. The results presented in this report emphasize the importance of interaction between refugees and Germans. In the future, access to mentorship programs should be facilitated for additional groups, such as refugee women and refugees in rural areas.

An exploration of factors influencing Public Health Nurses' capacity to engage in health promotion
Creators: name: Dhari, Ranjit Kaur
Publisher: name: University of British Columbia
Year: 2013

description: In the 1980s Canada was viewed as a leader in health promotion with the articulation of a framework to move health promotion into nursing practice, which was influential in structuring public health programs (Crichton, 2000; Richard et al., 2010; Stewart, 2000). Over time, public health nursing has experienced a shift in emphasis from health promotion—characterized by building healthy public policy, creating supportive environments, strengthening community action, developing personal skills, and reorienting health services (Ward & Verrinder, 2008)—to population health, with its emphasis on the management of risk factors through activities such as screening, disease prevention, and immunizations. The objective of this research inquiry was to understand the range and nature of influences on Public Health Nurses’ capacity to engage in health promotion work in a public health agency. Institutional ethnography methodology was utilized to understand the ruling relations, the forces that have the power to shape the day-to-day realities for Public Health Nurses and the agencies they work in. Interviews from 12 experienced Public Health Nurses, from different practice settings, were examined as an “entry into the social relations of the setting” (Smith, 2006, p. 92). The following influences have diminished the Public Health Nurse’s role in health promotion: (a) the changing context and increasing acuity of public health nursing practice; (b) operational influences on Public Health Nurses’ capacity to engage in health promotion (including time, budget, and other factors); (c) weakening relationships with community partners; (d) organizational leaders’ perceived lack of understanding of the Public Health Nurse’s role; and (e) centralized decision making. Public Health Nurses’ conceptualizations of health promotion are affected by these factors. The implications of these findings for public health nursing practice are discussed and recommendations for future research are made.

Se esiste infatti una possibilità di definizione, per il pensiero e l'opera di Emil Michel Cioran, essa risiede proprio in questa parola così affilata e, al contempo, così vaga. Eterodosso rispetto a qualunque ortodossia, Cioran corrisponde al suo destino di pensatore dispiegando un pensiero frammentario che si declina come feccia, come residuo. E donandoci un'opera miracolosa per tono e stile, per la capacità di mostrare il lavorio del silenzio attraverso le parole, per la possibilità di dire nascondendo.

description: The coronavirus pandemic has affected the Gulf countries in a particular way. In addition to the direct consequences of the pandemic, the spread of the coronavirus has led to a collapse in demand for the Gulf countries’ most important source of revenue: oil. Its price, which had fallen initially due to the price war between Saudi Arabia and Russia, collapsed in spring 2020. Although it recovered somewhat afterwards, no rebound is in sight. Market simulations by DIW Berlin that analyze the future price development demonstrate there is a clear risk of the downward trend continuing in the short term. As a result, export revenue is likely to further decline in the Gulf states. The countries’ fiscal space will shrink due to pandemic-related additional expenses as well. Generally, long-term challenges faced by this region, such as diversification and the possibility of a global energy transition, are at the risk of not being properly addressed

description: A remarkable hardening (~ 30 cm-1) of the normal mode of vibration associated with the symmetric stretching of the oxygen octahedra for the Ba2FeReO6 and Sr2CrReO6 double perovskites is observed below the corresponding magnetic ordering temperatures. The very large magnitude of this effect and its absence for the anti-symmetric stretching mode provide evidence against a conventional spin-phonon coupling mechanism. Our observations are consistent with a collective excitation formed by the combination of the vibrational mode with oscillations of local Fe or Cr 3d and Re 5d occupations and spin magnitudes.

description: The high international capital positions of offshore financial centers (OFCs) have led to increasing research in the area. However, many unanswered questions remain, as OFC activities are secretive by nature and data is sparse. It is, for example, not even clear whether the financial industry actually physically operates on OFCs or if it artificially books services from other countries. Using a new research approach that examines the effects of extreme storm events such as Hurricane Irma on local conditions and financial service activities on small islands, this paper shows that offshore services are likely booked primarily from other countries. If this is the case, the current approach of regulating offshore financial services through regulation targeting the offshore financial center is inherently limited.

description: As the world’s largest payments for ecosystem services (PES) program, China’s Sloping Land Conversion Program (SLCP) is designed to combat soil erosion and land degradation by converting cropland on steep slopes into forests. Operating through an incentive-based approach, the SLCP involved 32 million rural households as core agents. This paper aims to fill a research gap regarding how socioeconomic and institutional conditions influence rural households to reach the primary environmental goals. Using fuzzy-set qualitative comparative analysis (fsQCA), we conclude that at the household level, the different pathways to environmental success or failure have been shaped by socioeconomic and institutional conditions in a combinatory manner rather than single conditions alone. Specifically, the combination of household involvement and effective monitoring plays a fundamental role in capacity-building between government and households. We found that financial incentives have a trade-off effect, as they could not only create a positive interaction but also trigger failure in situations with different conditions. Finally, the potential and limits of QCA were discussed, and we call for a more serious reflection on the added value of QCA as an alternative or complementary method to conventional approaches in environmental governance research.

description: Two traditional options for reforming Ehegattensplitting, the joint taxation of married couples with full income splitting, are de facto income splitting (Realsplitting) or individual taxation with a transferable personal allowance. However, these proposals do not significantly reduce the marginal tax burden on the secondary earner’s income and therefore only minimally encourage married women to participate in the labor market. Another option for reform is an additional personal allowance for married couples, but this concept is difficult to understand and further benefits dual income couples with middle and high incomes. Moreover, alternative methods of taxing married couples in Germany must adhere to specific legal regulations. A satisfactory compromise would thus be de facto income splitting for married couples with a transferable amount equal to the personal allowance. This proposal fulfills the legal criteria, is easily understandable, generates a certain amount of additional tax revenue, avoids burdening the lower and middle income brackets, and encourages secondary earners to participate in the labor market.

description: If the expansion of the early Universe was not close to de Sitter, the statistical imprints of the primordial density perturbation on the cosmic microwave background can be quite different from those derived in slow-roll inflation. In this paper we study the inflationary signatures of all single-field models which are free of ghost-like instabilities. We allow for a rapid change of the Hubble parameter and the speed of sound of scalar fluctuations, in a way that is compatible with a nearly scale-invariant spectrum of perturbations, as supported by current cosmological observations. Our results rely on the scale-invariant approximation, which is different from the standard slow-roll approximation. We obtain the propagator of scalar fluctuations and compute the bispectrum, keeping next-order corrections proportional to the deviation of the spectral index from unity. These theories offer an explicit example where the shape and scale-dependences of the bispectrum are highly non-trivial whenever slow-roll is not a good approximation.

description: The optimisation of two-dimensional (2D) lattice ion trap geometries for trapped ion quantum simulation is investigated. The geometry is optimised for the highest ratio of ion-ion interaction rate to decoherence rate. To calculate the electric field of such array geometries a numerical simulation based on a "Biot-Savart like law" method is used. In this article we will focus on square, hexagonal and centre rectangular lattices for optimisation. A method for maximising the homogeneity of trapping site properties over an array is presented for arrays of a range of sizes. We show how both the polygon radii and separations scale to optimise the ratio between the interaction and decoherence rate. The optimal polygon radius and separation for a 2D lattice is found to be a function of the ratio between rf voltage and drive frequency applied to the array. We then provide a case study for 171Yb+ ions to show how a two-dimensional quantum simulator array could be designed.

description: As the German constitution aims for equal living conditions, a huge number of political measures to enhance the conditions in the new states were undertaken after unification (known as the “Aufbau Ost”). In the new states, expenditure per capita rose significantly over the average expenditure of the old states and their municipalities and huge budget deficits occurred. Beginning in the mid-1990s, expenditure in the new states developed noticeably more reservedly than in the old states. Although the gradual consolidation of public finances has been made significantly more difficult due to the population decline, the majority of budgets in the new states have had budget surpluses for nearly 15 years now. Despite this, the demographic change will soon again pose problems for eastern German budgets. The foreseeable population development will create permanent pressure on public expenditure, which will be much higher in the new states than in the old states. As a result, the eastern states’ leeway in public budgets will be smaller compared to the western states’, posing the danger that investments will be neglected and that regional policy measures for an economic catch-up process will be neglected. Therefore, policymakers should consider integrating the shrinking and aging German population as a factor in the federal fiscal equalization system.

description: Spin Hall nano-oscillators convert DC to magnetic auto-oscillations in the microwave regime. Current research on these devices is dedicated to creating next-generation energy-efficient hardware for communication technologies. Despite intensive research on magnetic auto-oscillations within the past decade, the nanoscale mapping of those dynamics remained a challenge. We image the distribution of free-running magnetic auto-oscillations by driving the electron spin resonance transition of a single spin quantum sensor, enabling fast acquisition (100 ms/pixel). With quantitative magnetometry, we experimentally demonstrate for the first time that the auto-oscillation spots are localized at magnetic field minima acting as local potential wells for confining spin-waves. By comparing the magnitudes of the magnetic stray field at these spots, we decipher the different frequencies of the auto-oscillation modes. The insights gained regarding the interaction between auto-oscillation modes and spin-wave potential wells enable advanced engineering of real devices.

description: A uniform parametrization for the irreducible spin representations of Weyl groups in terms of nilpotent orbits is recently achieved by Ciubotaru (2011). This paper is a generalization of this result to other real reflection groups. Let $(V_0, R, V_0^{\vee}, R^{\vee})$ be a root system with the real reflection group $W$. We define a special subset of points in $V_0^{\vee}$ which will be called solvable points. Those solvable points, in the case $R$ crystallographic, correspond to the nilpotent orbits whose elements have a solvable centralizer in the corresponding Lie algebra. Then a connection between the irreducible spin representations of $W$ and those solvable points in $V_0^{\vee}$ is established.

description: Many proposals for solid-state photonic implementations of quantum information processing utilize high-quality optical resonators to achieve strong coupling between guided fields and heterogeneously incorporated qubits. Given the practical difficulty of accurately placing quantum dots, vacancy centers, or other such atom-like emitters throughout a complex nanophotonic circuit, it would be natural to consider whether high-quality resonators could be used in conjunction with bulk optical nonlinearities to create optically-coupled qubit degrees of freedom via lithographic patterning of a homogeneous medium. A recent limit theorem for quantum stochastic differential equations can be used to prove rigorously that this should be possible, in principle, using resonators incorporating a strongly Kerr-nonlinear, $χ^{(2)}$-nonlinear, or two-photon absorbing material with very low loss at the fundamental optical wavelength.

Automated diagnoses of safety problems at collision prone intersections using computer vision techniques
Creators: name: Mahiban, Aaron
Publisher: name: University of British Columbia
Year: 2013

description: Road safety studies attempt to develop solutions to deficiencies by identifying causes and prescribing remedies. Most often, traffic safety engineers use collision information to detect potential problem locations and to provide assessments of treatments. The main short-coming of this technique is that it analyzes past information to determine whether a problem exists. This reactive approach requires an expert tasked to improve safety having to stand by and wait for collisions to occur. Many experts have recognized the need for a more proactive approach in order to reduce the analysis period and provide timely safety improvements. One particularly promising alternative is the use of traffic conflicts as surrogates to actual collisions. Conflict data collection offers many benefits to that of collisions, including their relative frequency, and marginal social cost. Traffic conflict studies can be deployed in any location, need little planning, and do not require a vigilant database maintenance. However, since trained human reviewers are required there are significant costs associated with in-situ conflict observation studies. Furthermore, traffic conflict studies also rely on human judgement, which introduces subjectivity into results. The goal, therefore, is to find a way to harness data-rich traffic conflicts that is both efficient and fundamentally objective. This thesis presents the novel use of an automated traffic conflict detection tool to diagnose safety issues at intersections with known safety deficiencies. Two intersections were analyzed to determine which movement types were over-represented. Once the most dangerous movements were identified, characteristics of the road user, environment, and conflicts themselves were analyzed to provide an educated recommendation for safety improvement. When the treatments had been implemented for some time, additional data was collected and similarly analyzed to determine whether it had achieved the intended goal. The outcomes of this research provide evidence that objective and surrogate safety indicators can effectively be used to identify safety problems at intersections. In addition, the rich data collected using the automated traffic conflict technique can be mined to understand the mechanisms leading to and resulting in offending conflicts. This information can help traffic safety experts make informed decisions for focused countermeasure implementation.

description: In this paper we present a new algorithm for the solution of Hamilton-Jacobi-Bellman equations related to optimal control problems. The key idea is to divide the domain of computation into subdomains which are shaped by the optimal dynamics of the underlying control problem. This can result in a rather complex geometrical subdivision, but it has the advantage that every subdomain is invariant with respect to the optimal dynamics, and then the solution can be computed independently in each subdomain. The features of this dynamics-dependent domain decomposition can be exploited to speed up the computation and for an efficient parallelization, since the classical transmission conditions at the boundaries of the subdomains can be avoided. For their properties, the subdomains are patches in the sense introduced by Ancona and Bressan [ESAIM Control Optim. Calc. Var., 4 (1999), pp. 445-471]. Several examples in two and three dimensions illustrate the properties of the new method.

description: Work and family life arrangements differed greatly between the east and west before German reunification in 1990. Since reunification, however, the employment rates of mothers with children requiring childcare have converged. This trend is accompanied by a growing approval of maternal employment, especially in western Germany. However, differences in actual working hours remain. Mothers in the east work full time markedly more often compared to mothers in the west. However, women in younger age cohorts approve less of working mother with toddlers compared to women in older age cohorts, especially in the east. It remains to be seen whether a further expansion of day care in childcare centers and elementary schools will lead to a change in attitudes and thus also in the full-time employment of mothers with young children.

description: Vaginal progesterone and cervical pessary are both shown to be effective in preventing preterm. We conducted a meta-analysis to evaluate whether the combination of these two interventions has any additional benefit in preventing preterm birth and improving perinatal outcomes in asymptomatic women with a singleton gestation who had a midtrimester sonographic short cervix compared with vaginal progesterone alone. Five databases were searched from their inception to 21 February 2019. We estimated relative risk (RR) and 95% confidence intervals (CIs) for dichotomous outcomes. The primary outcome was preterm birth <34 weeks, and second outcomes included low birth weight (LBW) delivery, perinatal death, and neonatal intensive care unit (NICU) admission. Three RCTs with a total of 820 participants were identified. Cervical pessary had no significant prevention effect of preterm birth when combined with vaginal progesterone compared to the control group with vaginal progesterone alone (RR = 0.91; 95% CI, 0.47–1.77). No significant difference has been revealed between groups in LBW delivery (RR = 1.13; 95% CI, 0.86–1.48), perinatal death (RR = 1.27; 95% CI, 0.58–2.78) and NICU admission (RR = 1.24; 95% CI, 0.84–1.85). Comparing with vaginal progesterone alone, cervical pessary plus vaginal progesterone did not reduce the rates of preterm birth at <34 weeks of gestation. There was no difference in LBW delivery, perinatal death, and NICU admission. We need more evidence to balance the benefit and side effects on the combination of vaginal progesterone and cervical pessary for preventing preterm birth.

description: The aim of this paper is to study the relationship between Hamiltonian dynamics and constrained variational calculus. We describe both using the notion of Lagrangian submanifolds of convenient symplectic manifolds and using the so-called Tulczyjew's triples. The results are also extended to the case of discrete dynamics and nonholonomic mechanics. Interesting applications to geometrical integration of Hamiltonian systems are obtained.

description: The German economy has bottomed out, but its recovery is going to be long and arduous. Nevertheless, following the almost two-digit slump in economic output in the second quarter of 2020, recovery is likely to be accompanied by above-average rates. However, it is assumed that a second wave will not occur and lockdown-like measures will not be reimplemented. Private consumption in particular will markedly increase over the third and fourth quarters of 2020. Short-time work is declining, contributing to the increase in disposable income. Additionally, households saved considerably during the height of the pandemic in spring 2020 and are spending their savings gradually over the second half of the year. The VAT reduction and further stimulus program measures are supporting consumption and thus the economy. In contrast, the recovery in foreign demand for German products is likely to be more protracted. The economy and labor markets in many countries have been hit much harder than in Germany, and demand for consumer durables and capital goods – the focus of Germany’s export industry – in particular is likely to be subdued. The pre-crisis level of economic activity will likely not be reached until early 2022. In 2020, German GDP is expected to drop by an annual average of 6.0 percent and grow by 4.1 and 3.0 percent in 2021 and 2022, respectively.

description: The coronavirus pandemic caused a global market crash in the first half of 2020. Following a massive slump of around four percent in the first quarter, global GDP decreased in the second by five percent. Lower rates of new infections, together with far-reaching monetary and fiscal policy measures to dampen the economic impact of the pandemic, ensure that production and the trust of consumers and firms will slowly return. Notably, China’s quick economic recovery is inspiring hope. As long as the rate of new infections does not con- tinue to rise, global production in the third quarter is likely to increase markedly. DIW Berlin calculates that global produc- tion will shrink by 4.0 percent in 2020. During the forecast period, the global economy is likely to grow at quite strong rates of 5.8 percent in 2021 and 4.0 percent in 2022. However, risks still exist: if infection rates grow substantially again, a sig- nificant increase in insolvencies, combined with a rise in loan defaults, could destabilize the financial markets and ultimately threaten the solvency of some states

ABSTRACT:
The purpose of the paper consists in examining the cases submitted to the European Court of Human Rights in which religious freedom (art. 9 of European Convention of Human Rights) is, in a specific way, related to the right to education (art. 1 of Protocol 1). The fields where arise most important problems are as follows: family relationship, denominational Schools, compulsory denominational (confessional) instruction in Schools, religious symbols in State Schools. From the latest judgments at Strasbourg Court, it seems to emerge a new perspective of the principle of laicità, clearly open to social pluralism. As the Court stated concerning educative pluralism: “the possibility of pluralism in education […] is essential for the preservation of the “democratic society” as conceived by the Convention”.
