description: Water is a key input in the production of many goods and services and under certain conditions can become a critical limiting factor with significant impacts on regional development. This is the case of many agricultural European Mediterranean basins, where water deficit during drought events is partially covered by illegal abstractions, mostly from aquifers, which are tolerated by the authorities. Groundwater overexploitation for irrigation has created in these areas an unprecedented environmental catastrophe that threatens ecosystems sustainability, urban water supply and the current model of development. Market-based drought insurance systems have the potential to introduce the necessary incentives to reduce overexploitation during drought events and remove the high costs of the drought indemnity paid by the government. This paper develops a methodology to obtain the optimum risk premium based on concatenated stochastic models. The methodology is applied to the agricultural district of Campo de Cartagena (Segura River Basin, Spain). Results show that the prices in a hypothetic competitive private drought insurance market would be reasonable and the expected environmental outcomes significant.

description: The electronic structure of nanoscopic oxide-coated aluminum islands is investigated using a tight-binding model that incorporates the geometry, chemistry and disorder of the particle. The oxide coat is found to significantly increase the volume accessible to electrons at the Fermi level. The level statistics agree with random matrix theory predictions. States near the Fermi level show pronounced clustering regardless of disorder. It is suggested that the observed clusters of tunneling resonances may have a more complex origin than if they were solely due to many-body non-equilibrium effects.

description: One of the applications of center-based clustering algorithms such as K-Means is partitioning data points into K clusters. In some examples, the feature space relates to the underlying problem we are trying to solve, and sometimes we can obtain a suitable feature space. Nevertheless, while K-Means is one of the most efficient offline clustering algorithms, it is not equipped to estimate the number of clusters, which is useful in some practical cases. Other practical methods which do are simply too complex, as they require at least one run of K-Means for each possible K. In order to address this issue, we propose a K-Means initialization similar to K-Means++, which would be able to estimate K based on the feature space while finding suitable initial centroids for K-Means in a deterministic manner. Then we compare the proposed method, DISCERN, with a few of the most practical K estimation methods, while also comparing clustering results of K-Means when initialized randomly, using K-Means++ and using DISCERN. The results show improvement in both the estimation and final clustering performance.

description: For S=1 system with general isotropic nearest-neighbor exchange, we derive the low-energy description of the spin nematic phase in terms of the RP^{2} nonlinear sigma-model. In one dimension, quantum fluctuations destroy long-range nematic (quadrupolar) ordering, leading to the formation of a gapped spin liquid state being an analog of the Haldane phase for a spin nematic. Nematic analog of the Belavin-Polyakov instanton with π_{2} topological charge 1/2 is constructed. In two dimensions the long-range order is destroyed by thermal fluctuations and at finite temperature the system is in a renormalized classical regime. Behavior in external magnetic field is discussed.

Reversible quantum Brownian heat engines for electrons

description: Brownian heat engines use local temperature gradients in asymmetric potentials to move particles against an external force. The energy efficiency of such machines is generally limited by irreversible heat flow carried by particles that make contact with different heat baths. Here we show that, by using a suitably chosen energy filter, electrons can be transferred reversibly between reservoirs that have different temperatures and electrochemical potentials. We apply this result to propose heat engines based on mesoscopic semiconductor ratchets, which can quasistatically operate arbitrarily close to Carnot efficiency.

Education as a public and common good: Revisiting the role of the State in a context of growing marketization
Creators: name: LOCATELLI, Rita
Publisher: name: Universit� degli studi di Bergamo
Year: 2017

description: The global education landscape is undergoing significant changes. These are characterized by the greater involvement of non-state actors in educational policy and provision, as well as by the growing scale of for-profit education at all levels. Under the trends of education privatization lies the assumption that the private sector can provide better quality education and, when functioning as corporate or business organizations, be more efficient also in the management of the education system. Moreover, the education decision-making process is shifting from a national to a global level. Indeed, regional and global initiatives are increasingly influencing national policies and practices, encouraging the development of for-profit private education. These dynamics enhance the adoption of free-market logics, notably those of choice, economic competition and performance.
The spread of market approaches in the education sector poses important questions about both the organization of education systems and the purposes of education itself. Whether education is considered to be a public or private marketable good is related to two different interpretations of ?education? in education policy. This study aims to analyze the implications that growing for-profit private engagement in schooling has for the role of the State and for the democratic governance of education. It aims to examine complementary frameworks for the governance of education that may favor democratic participation and a humanistic approach while countering neoliberal influences in the sector.
Understanding education as a public good implies that States are responsible for protecting fundamental principles of equity, equality, social justice, and human rights, as well as regulating, financing and providing education, particularly at basic and compulsory levels. While reaffirming the primary responsibility of the State in the governance of education, understanding education as a common good also requires that the process of producing and benefitting from education is intrinsically shared. Overcoming the utilitarian tradition of ?decomposable goods?, the notion of common goods suggests that education incorporates common understandings of its value, grounded in specific cultural and social backgrounds. This concept calls for the development, both at a national and at a global level, of political institutions that enable citizens to have greater voice in the decisions that affect their well-being.
Securely Computing the $n$-Variable Equality Function with $2n$ Cards

description: Research in the area of secure multi-party computation using a deck of playing cards, often called card-based cryptography, started from the introduction of the five-card trick protocol to compute the logical AND function by den Boer in 1989. Since then, many card-based protocols to compute various functions have been developed. In this paper, we propose two new protocols that securely compute the $n$-variable equality function (determining whether all inputs are equal) $E: \{0,1\}^n \rightarrow \{0,1\}$ using $2n$ cards. The first protocol can be generalized to compute any doubly symmetric function $f: \{0,1\}^n \rightarrow \mathbb{Z}$ using $2n$ cards, and any symmetric function $f: \{0,1\}^n \rightarrow \mathbb{Z}$ using $2n+2$ cards. The second protocol can be generalized to compute the $k$-candidate $n$-variable equality function $E: (\mathbb{Z}/k\mathbb{Z})^n \rightarrow \{0,1\}$ using $2 \lceil \lg k \rceil n$ cards.

description: Forsteropsalis tumida (Forster 1944) new combination
(Figs 124–127)
 Megalopsalis tumida Forster 1944: 188–189, figs 4–6.
 Material examined. Male holotype. WN. Khandallah, near Wellington, New Zealand, 1924, R.E. R. Grimmett (MONZ 2 /14).
 Description. MALE (N = 1). Prosoma length 3.8, width 5.2. Prosoma entirely unarmed; mottled dark brown and yellow-brown, with yellow U-shaped stripe around ocularium; metapeltidium not sclerotised. Ocularium yellow-brown with dark margins around eyes. Dorsum and venter of opisthosoma yellow-brown. Coxae yellowbrown, with black setae.
 Chelicerae (figs 125–126). Segment I 9.0, segment II 13.0. Orange; segment II enormously swollen, with long, thin fingers.
 Pedipalps (fig. 127). Femur 6.6, patella 3.0, tibia 3.6, tarsus 7.0. Orange; extraordinarily long; femur lightly denticulate; small, pointed patellar apophysis; small hypersetose areas on margin of apophysis and distal end of tibia; no tooth-row on claw.
 Legs. Leg I femur 10.0, patella 2.0, tibia 9.0; leg II femur 13.5, patella 2.5, tibia 14.0; leg III not preserved; leg IV femur 9.0, patella 2.0, tibia 10.0. Orange; femora dorsally denticulate. Tibia II with nine pseudosegments; tibia IV with two pseudosegments.
 Comments. This species is of doubtful validity. It is very similar to Forsteropsalis fabulosa, essentially being distinguished only by the more globular chelicerae which may represent individual variation. Forster (1944) failed to recognise a connection between his new species and F. fabulosa because he had confused the latter with the male of Forsteropsalis inconstans (see comments for F. fabulosa above).
 Forsteropsalis tumida has previously been recorded from the Waitomo cave system (Meyer-Rochow & Liddle 1988). The location of specimens used in that study (if they were preserved) is unknown (V. B. Meyer-Rochow, personal communication 2002), but a specimen photographed by Meyer-Rochow & Liddle (1988) is clearly distinct from F. tumida and represents an unknown species.

description: OBJECTIVES: To analyze empirical studies from the United States and Canada to gain an understanding on how nursing education affects nursing students' attitudes toward persons who are aged. DESIGN: An integrative literature review was completed using Garrard's (2011) Matrix Method. DATA SOURCES: Articles were identified through the electronic database search engines of CINAHL, Pub Med, and Academic Search Complete. Only peer reviewed research articles from 2009 to 2015 were reviewed. REVIEW METHODS: A review matrix was created to abstract information from 11 studies so that synthesis could occur. Information in the columns of the review matrix was used to compare the studies. Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) 27 item check list was used to help with reporting the findings. Studies were graded using the American Association of Critical Care Nurses' (AACN) level of evidence. RESULTS: A key finding is student engagement with gerontological content in the classroom or clinical setting results in improving nursing students' attitudes toward persons who are aged. CONCLUSIONS: Several gaps exist in the literature. Further research including longitudinal studies and large scale, multi-site samples would add to the existing knowledge.

description: This paper provides a detailed overview of the differences across EU member states’ labour markets,through the extensive use of descriptive statistics. The objective is two-fold: firstly, it identifies the commonalities and differences in rural labour markets across EU regions and their developments, with special regard to agriculture, and secondly it emphasises the constraints that may hinder the efficient functioning of labour markets. Therefore, the paper starts with a description of the main indicators in the general labour market theory, such as the structure of the population in terms of age and gender distribution, unemployment and activity rates, employment levels, quality of human capital, migration patterns, and so forth. Secondly, we focus on the differences among rural and urban areas to then look closely at the agricultural sector. The institutional framework in which labour market institutions operate is also included. Lastly, as an attempt to summarise the analysis and to classify the EU member states according to certain rural and specific agricultural indicators, cluster analysis is also employed. Policy implications include investment in human capital and vocational training, support to young farmers, promoting economic diversification and upgrading infrastructure, with special regard to the new member states and to the Southern parts of Europe.
The effect of velocity anisotropy on the antiferromagnetic instability of a d-wave superconductor

description: We consider the effective 2+1 dimensional electrodynamics (QED_3) of low-energy quasiparticles coupled to fluctuating vortex loops in the d-wave superconductor, with the velocity anisotropy: v_F not equal to v_Delta. This theory should be relevant to the quantum superconductor-insulator transition in underdoped cuprates. Working in the customary large-N approximation, we find that weak anisotropy is a marginally irrelevant perturbation to the Lorentz invariant QED_3, and that the critical number N_c of Dirac fields below which the theory suffers the antiferromagnetic (chiral) instability stays the same.

Radiative accelerations on Ne in the atmospheres of late B stars

description: Radiative accelerations on Ne are calculated for the atmospheres of main sequence stars with 11000 < Teff < 15000 K, corresponding to the range of the HgMn stars. The calculations take into account neon fine structure as well as shadowing of neon lines using the entire Kurucz line list, bound-bound, bound-free, and free-free opacity of H, He, and C as well as some NLTE effects. NLTE effects modify the radiative acceleration by a factor of order 100 in the outer atmosphere. The dependence of the radiative acelerations on the Ne abundance, Teff, and gravity is studied. Radiative accelerations are well below gravity in the entire range of Teff and it is predicted that in stable atmospheres Ne should sink and be observed as underabundant. This agrees with recent observations of low Ne abundances in HgMn stars.

description: An understanding of the diversity of community water systems (CWS) in the United States is essential when evaluating the financial implications of the 1986 and subsequent amendments to the Safe Drinking Water Act (SDWA). This diversity, in terms of size, primary water source, ownership, and existing levels of treatment, shape the nature of the technical, institutional, and financial issues that must be confronted in moving these systems toward compliance with SDWA regulations. This report provides a descriptive summary of these operating and design characteristics ofCWS's across the country. The data are organized to help provide a typology of representative public water systems that can be examined to better understand the regional effects of policy implementation. The focus of the analysis is on small water systems, those most burdened by the expanded montoring and treatment regulations; much of the data are also provided for larger systems for purposes of comparison and completeness. Emphasis is directed towards current water treatment objectives being pursued by CWS's and the treatment processes already in place. It is for those smaller systems that may require the addition of multiple water treatment processes that the financial implications are likely to be most severe. As would be expected, there is a shortfall between the number of systems serving fewer than 10,000 people employing multiple treatment processes and the estimated number required. There are systems, however, that have demonstrated success with a number of multiple treatment processes, particularly in the small and medium-size categories. The experience gained by these systems would seem invaluable in efforts to accelerate the process of field testing and approval of technologies applicable to systems serving lower population levels.

description: TIrroughout the debate over re-authorization of the Safe Drinking Water Act (SDWA), it has been clear that members of both Houses of Congress are keenly aware of the financial burden facing the owners of small water systems in their efforts to comply with the 1986 and future amendments to the SDWA. The most reliable source of funds for drinking water and wastewater improvements for small systems has been the Water and Waste Disposal Loan and Grant Program administered through the Rural Utilities Service (RUS) of the USDA's Rural Development mission area. This report provides some background of the RUS loan and grant program. Specific attention is directed towards New York's Rural Development efforts where we develop small system cost models related to treatment and distribution improvements. Over the past 50 years, RUS has been the primary source of low-cost financing to rural water and waste disposal systems, providing over 35,000 loan and grant funding packages totaling nearly $18 billion. Despite the recent increases in obligations in nominal terms, the real purchasing power of these funds has yet to rebound to pre-1980 levels. Due to EPA's efforts to enforce the 1986 and later amendments to the SDWA, combined with the aging of water system infrastructure, the demand for these funds consistently outweighs available obligation levels. Data from nearly 150 small water system improvement projects in New York State receiving RUS funding are evaluated to determine the extent of improvements related to SDWA regulations. Operating revenues and expenses are relatively similar across the state; however residual funds for future capital improvements after reducing net incomes by principle and interest payments are nonexistent. While public water systems should not accumulate large surplus funds, the small residuals remaining are surely insufficient to support any major capital improvements in the future. The costs of treatment varied widely by treatment technology and system size. An indirect cost function was specified regressing annualized treatment and operating costs on system population, water source, and treatment variables. While the economies are substantial for very small systems, for some technologies, they are nearly exhausted at service populations of around 3,300. An indirect cost function for distribution and transmission improvements was specified.

description: We analyze triple systems composed of the super massive black hole (SMBH) near the center of M87 and a pair of black holes (BHs) with masses in the range $10-10^3$ $M_{\odot}$. We consider the post Newtonian precession as well as the Kozai-Lidov interactions at the quadruple and octupole levels in modeling the evolution of binary black hole (BBH) under the influence of the SMBH. Kozai-Lidov oscillations enhance the gravitational wave (GW) signal in some portions of the parameter space. We identify frequency peaks and examine the detectability of GWs with LISA as well as future observatories such as $μ$Ares and DECIGO. We show examples in which GW signal can be observed with a few or all of these detectors. Multi-Wavelength GW spectroscopy holds the potential to discover stellar to intermediate mass BHs near the center of M87. We estimate the rate, $Γ$, of collisions between the BBHs and flyby stars at the center of M87. Our calculation suggests $Γ< 10$ $\rm{Gyr}^{-1}$ for a wide range of the mass and semi-major axes of the inner binary.

description: M. Lin defined a binary operation for two positive semi-definite matrices in studying certain determinantal inequalities that arise from diffusion tensor imaging. This operation enjoys some interesting properties similar to the operator geometric mean. We study this operation further and present numerous properties emphasizing the relationship with the operator geometric mean. In the end, we present an application toward Tsallis relative operator entropy.

description: Pandemics involve the high transmission of a disease that impacts global and local health and economic patterns. The impact of a pandemic can be minimized by enforcing certain restrictions on a community. However, while minimizing infection and death rates, these restrictions can also lead to economic crises. Epidemiological models help propose pandemic control strategies based on non-pharmaceutical interventions such as social distancing, curfews, and lockdowns, reducing the economic impact of these restrictions. However, designing manual control strategies while considering disease spread and economic status is non-trivial. Optimal strategies can be designed through multi-objective reinforcement learning (MORL) models, which demonstrate how restrictions can be used to optimize the outcome of a pandemic. In this research, we utilized an epidemiological Susceptible, Exposed, Infected, Recovered, Deceased (SEIRD) model: a compartmental model for virtually simulating a pandemic day by day. We combined the SEIRD model with a deep double recurrent Q-network to train a reinforcement learning agent to enforce the optimal restriction on the SEIRD simulation based on a reward function. We tested two agents with unique reward functions and pandemic goals to obtain two strategies. The first agent placed long lockdowns to reduce the initial spread of the disease, followed by cyclical and shorter lockdowns to mitigate the resurgence of the disease. The second agent provided similar infection rates but an improved economy by implementing a 10-day lockdown and 20-day no-restriction cycle. This use of reinforcement learning and epidemiological modeling allowed for both economic and infection mitigation in multiple pandemic scenarios.

Amplitude and phase representation of quantum invariants for the time dependent harmonic oscillator
Creators: name: Guasti, M. Fernandez
name: Moya-Cessa, H.
Publisher: name: arXiv
Year: 2002
Subjects: subject: Quantum Physics (quant-ph)

description: The correspondence between classical and quantum invariants is established. The Ermakov Lewis quantum invariant of the time dependent harmonic oscillator is translated from the coordinate and momentum operators into amplitude and phase operators. In doing so, Turski's phase operator as well as Susskind-Glogower operators are generalized to the time dependent harmonic oscillator case. A quantum derivation of the Manley-Rowe relations is shown as an example.

description: Tidal streams are highly sensitive to perturbations from passing dark matter (DM) subhalos and thus provide a means of measuring their abundance. In a recent paper, we analyzed the distribution of stars along the GD-1 stream with a combination of data from the Gaia satellite and the Pan-STARRS survey, and we demonstrated that the population of DM subhalos predicted by the cold dark matter (CDM) paradigm are necessary and sufficient to explain the perturbations observed in the linear density of stars. In this paper, we use the measurements of the subhalo mass function (SHMF) from the GD-1 data combined with a similar analysis of the Pal 5 stream to provide novel constraints on alternative DM scenarios that predict a suppression of the SHMF on scales smaller than the mass of dwarf galaxies, marginalizing over uncertainties in the slope and normalization of the unsuppressed SHMF and the susceptibility of DM subhalos in the inner Milky Way to tidal disruption. In particular, we derive a 95% lower limit on the mass of warm dark matter (WDM) thermal relics $m_{\rm WDM}>3.6\,\mathrm{keV}$ from streams alone that strengthens to $m_{\rm WDM}>6.2\,\mathrm{keV}$ when adding dwarf satellite counts. Similarly, we constrain the axion mass in ultra-light ("fuzzy") dark matter (FDM) models to be $m_{\rm FDM}>1.4\times10^{-21}\,\mathrm{eV}$ from streams alone or $m_{\rm FDM}>2.2\times10^{-21}\,\mathrm{eV}$ when adding dwarf satellite counts. Because we make use of simple approximate forms of the streams' SHMF measurement, our analysis is easy to replicate with other alternative DM models that lead to a suppression of the SHMF.

description: We report transport measurements down to T=60mK of SININ and SNIN structures in the diffusive limit. We fabricated Al-AlOx/Cu/AlOx/Cu (SININ) and Al/Cu/AlOx/Cu (SNIN) vertical junctions. For the first time, a zero bias anomaly was observed in a metallic SININ structure. We attribute this peak of conductance to coherent multi-reflections of electrons between the two tunnel barriers. This conductance maximum is quantitatively fitted by the relevant theory of mesoscopic SININ structures. When the barrier at the SN interface is removed (SNIN structure), we observe a peak of conductance at finite voltage accompagnied by an excess of sub-gap conductance.
