description: We show that dark energy and dark matter can be described simultaneously by ordinary Einstein gravity interacting with a single scalar field provided the scalar field Lagrangian couples in a symmetric fashion to two different spacetime volume-forms (covariant integration measure densities) on the spacetime manifold - one standard Riemannian given by the square-root of the determinant of the pertinent Riemannian metric and another non-Riemannian volume-form independent of the Riemannian metric, defined in terms of an auxiliary antisymmetric tensor gauge field of maximal rank. Integration of the equations of motion of the latter auxiliary gauge field produce an a priori arbitrary integration constant that plays the role of a dynamically generated cosmological constant or dark energy. Moreover, the above modified scalar field action turns out to possess a hidden Noether symmetry whose associated conserved current describes a pressureless "dust" fluid which we can identify with the dark matter completely decoupled from the dark energy. The form of both the dark energy and dark matter that results from above class of models is insensitive to the specific form of the scalar field Lagrangian. By adding appropriate perturbation, which breaks the above hidden symmetry and along with this it couples dark matter and dark energy, we also suggest a way to obtain growing dark energy in the present universe's epoch without evolution pathologies.

description: 1. Acquisition of a two-way shuttle-box avoidance response is facilitated by ethanol. This facilitated acquisition of an avoidance response to ethanol was attenuated during withdrawal from chronic-ethanol diet intake (i.e. tolerance developed by ethanol). The deficit in the avoidance task after chronic ethanol treatment could be overcome by increasing the dose of ethanol. 2. Flumazenil, a benzodiazepine antagonist, also facilitated acquisition of the avoidance response in control rats. This response to flumazenil was significantly reduced during withdrawal from chronic-ethanol treatment. This reduced avoidance responding during withdrawal also could be overcome by increasing the dose of flumazenil. 3. The benzodiazepine-inverse agonist, RO 15-4513, produced a deficit in avoidance responding that was antagonized by both ethanol and flumazenil in a dose-related manner. 4. To determine whether flumazenil has the properties of a benzodiazepine agonist, it was established that, unlike the benzodiazepine chlordiazepoxide, flumazenil did not enhance the ethanol-induced deficit in the aerial righting reflex. Additionally, flumazenil blocked the action of chlordiazepoxide in this procedure, consistent with the benzodiazepine antagonist action of flumazenil. 5. Data collected are consistent with the hypothesis that an endogenous substance with the properties of a benzodiazepine-inverse agonist antagonizes the anticonflict actions of acutely administered ethanol during withdrawal from chronic-ethanol exposure.

description: 1 Stimulation of P2Y‐purinoceptors on turkey erythrocytes and many other cell types results in activation of phospholipase C. In contrast, we have observed recently that P2Y‐purinoceptors on C6 rat glioma cells are not coupled to phospholipase C., but rather, inhibit adenylyl cyclase. 2 In this study we investigated the pharmacological selectivity of the P2‐purinoceptor antagonists, suramin, reactive blue 2, and pyridoxal phosphate 6‐azophenyl 2′,4′‐disulphonic acid (PPADS) for phospholipase C‐ and adenylyl cyclase‐coupled P2Y‐purinoceptors. 3 In C6 glioma cells, suramin and reactive blue 2 competitively antagonized the inhibitory effect of 2MeSATP on adenylyl cyclase (pK B = 5.4 ± 0.2 and 7.6 ± 0.1, respectively), whereas PPADS at concentrations up to 100 μm had no effect. 4 In contrast, in the turkey erythrocyte preparation, PPADS at concentrations up to 30 μm was a competitive antagonist of P2Y‐purinoceptor‐stimulated phospholipase C activity (pK B = 5.9 ± 0.1). Suramin and reactive blue 2 produced both a shift to the right of the concentration‐effect of 2MeSATP for the activation of phospholipase C and a significant decrease in the maximal inositol phosphate response. 5 Turkey erythrocytes also express a phospholipase C‐coupled β‐adrenoceptor. Concentrations of PPADS that competitively inhibited the P2Y‐purinoceptor‐mediated response had only minimal effects on the activation of phospholipase C by β‐adrenoceptors. In contrast, suramin and reactive blue 2 produced a non‐competitive inhibition, characterized by decreases in the maximal response to isoprenaline with no change in the potency of this β‐adrenoceptor agonist. 6 The differential effect of PPADS on P2Y‐purinoceptors of C6 glioma cells and turkey erythrocytes adds further support to the idea that different P2Y‐purinoceptor subtypes mediate coupling to adenylyl cyclic and phospholipase C.
Improvement of the envelope theory with the dominantly orbital state method

description: The envelope theory, also known as the auxiliary field method, is a simple technique to compute approximate solutions of Hamiltonians for $N$ identical particles in $D$ dimensions. The quality of the approximate eigenvalues can be improved by adding a free parameter in the characteristic global quantum number of the solutions. A method is proposed to determine the value of this parameter by comparing the eigenvalues computed with the envelope theory to the corresponding ones computed with a $N$-body generalization of the dominantly orbital state method. The accuracy of the procedure is tested with several systems.

description: 1. Analogues of adenine nucleotides inhibited beta-adrenoceptor-stimulated cyclic AMP accumulation in C6 rat glioma cells with a pharmacological selectivity consistent with that for involvement of a P2Y-purinoceptor. 2. The inhibitory effect of adenine nucleotides was completely prevented by pretreatment of cells with pertussis toxin. 3. The capacity of a series of recently synthesized 2-thioether analogues of adenine nucleotides to inhibit cyclic AMP accumulation was examined. Several ATP analogues, e.g. 2-cyclohexylthio and 2-hexylthio ATP, inhibited cyclic AMP accumulation with EC50 values of approximately 30 pM. These values represent 100,000 fold increases in potency over ATP. 4. Analogues of ADP exhibited the same remarkable increase in potency relative to their natural congener and diphosphates were at least as potent as the corresponding triphosphates at the C6 cell P2Y-purinoceptor. 5. The relative potencies of a broad series of agonists at the C6 cell receptor did not correspond to the relative potencies of the same compounds for activation of P2Y-purinoceptors on turkey erythrocyte membranes. Some agonists, particularly 2-thioether derivatives were more potent for stimulation of the C6 cell receptor, whereas other agonists were more potent in the turkey erythrocyte system. 6. These results add further support to the view that the adenylyl cyclase-linked P2Y-purinoceptor of C6 rat glioma cells is a different subtype from the phospholipase C-linked P2Y-purinoceptor of turkey erythrocyte membranes and several mammalian tissues.

description: We investigate the nonlinear wave dynamics of origami-based metamaterials composed of Tachi-Miura polyhedron (TMP) unit cells. These cells exhibit strain softening behavior under compression, which can be tuned by modifying their geometrical configurations or initial folded conditions. We assemble these TMP cells into a cluster of origami-based metamaterials, and we theoretically model and numerically analyze their wave transmission mechanism under external impact. Numerical simulations show that origami-based metamaterials can provide a prototypical platform for the formation of nonlinear coherent structures in the form of rarefaction waves, which feature a tensile wavefront upon the application of compression to the system. We also demonstrate the existence of numerically exact traveling rarefaction waves. Origami-based metamaterials can be highly useful for mitigating shock waves, potentially enabling a wide variety of engineering applications.

description: Animal coloration has traditionally been the target of genetic and evolutionary studies. However, until very recently, the study of the genetic basis of animal coloration has been mainly restricted to model species, whereas research on non-model species has been either neglected or mainly based on candidate approaches, and thereby limited by the knowledge obtained in model species. Recent high-throughput sequencing technologies allow us to overcome previous limitations, and open new avenues to study the genetic basis of animal coloration in a broader number of species and colour traits, and to address the general relevance of different genetic structures and their implications for the evolution of colour. In this review, we highlight aspects where genome-wide studies could be of major utility to fill in the gaps in our understanding of the biology and evolution of animal coloration. The new genomic approaches have been promptly adopted to study animal coloration although substantial work is still needed to consider a larger range of species and colour traits, such as those exhibiting continuous variation or based on reflective structures. We argue that a robust advancement in the study of animal coloration will also require large efforts to validate the functional role of the genes and variants discovered using genome-wide tools.This article is part of the themed issue ‘Animal coloration: production, perception, function and application’.

description: 1. A series of chain-extended 2-thioether derivatives of adenosine monophosphate were synthesized and tested as agonists for activation of the phospholipase C-linked P2Y-purinoceptor of turkey erythrocyte membranes, the adenylyl cyclase-linked P2Y-purinoceptor of C6 rat glioma cells, and the cloned human P2U-receptor stably expressed in 1321N1 human astrocytoma cells. 2. Although adenosine monophosphate itself was not an agonist in the two P2Y-purinoceptor test systems, eleven different 2-thioether-substituted adenosine monophosphate analogues were full agonists. The most potent of these agonists, 2-hexylthio AMP, exhibited an EC50 value of 0.2 nM for activation of the C6 cell receptor. This potency was 16,000 fold greater than that of ATP and was only 10 fold less than the potency of 2-hexylthio ATP in the same system. 2-hexylthio adenosine was inactive. 3. Monophosphate analogues that were the most potent activators of the C6 cell P2Y-purinoceptor were also the most potent activators of the turkey erythrocyte P2Y-purinoceptor. However, agonists were in general more potent at the C6 cell receptor, and potency differences varied between 10 fold and 300 fold between the two receptors. 4. Although 2-thioether derivatives of adenosine monophosphate were potent P2Y-purinoceptor agonists no effect of these analogues on the human P2U-purinoceptor were observed. 5. These results support the view that a single monophosphate is sufficient and necessary for full agonist activity at P2Y-purinoceptors, and provide insight for strategies for development of novel P2Y-purinoceptor agonists of high potency and selectivity.
"Regularity Singularities" and the Scattering of Gravity Waves in Approximate Locally Inertial Frames

description: It is an open question whether solutions of the Einstein-Euler equations are smooth enough to admit locally inertial coordinates at points of shock wave interaction, or whether "regularity singularities" can exist at such points. The term {\it regularity singularity} was proposed by the authors as a point in spacetime where the gravitational metric tensor is Lipschitz continuous ($C^{0,1}$), but no smoother, in any coordinate system of the $C^{1,1}$ atlas. An existence theory for shock wave solutions in $C^{0,1}$ admitting arbitrary interactions has been proven for the Einstein-Euler equations in spherically symmetric spacetimes, but $C^{1,1}$ is the requisite smoothness required for space-time to be locally flat. Thus the open problem of regularity singularities is the problem as to whether locally inertial coordinate systems exist at shock waves within the larger $C^{1,1}$ atlas. To clarify this open problem, we identify new "Coriolis type" effects in the geometry of $C^{0,1}$ shock wave metrics and prove they are essential in the sense that they can never be made to vanish within the atlas of {\it smooth} coordinate transformations, the atlas usually assumed in classical differential geometry. Thus the problem of existence of regularity singularities is equivalent to the question as to whether or not these Coriolis type effects are essentially non-removable and `real', or merely coordinate effects that can be removed, (in analogy to classical Coriolis forces), by going to the less regular atlas of $C^{1,1}$ transformations. If essentially non-removable, it would argue strongly for a `real' new physical effect for General Relativity, providing a physical context to the open problem of regularity singularities.

description: Using the two dimensional $XY-(S(O(3))$ model as a test case, we show that analysis of the Fisher zeros of the canonical partition function can provide signatures of a transition in the Berezinskii-Kosterlitz-Thouless ($BKT$) universality class. Studying the internal border of zeros in the complex temperature plane, we found a scenario in complete agreement with theoretical expectations which allow one to uniquely classify a phase transition as in the $BKT$ class of universality. We obtain $T_{BKT}$ in excellent accordance with previous results. A careful analysis of the behavior of the zeros for both regions $\mathfrak{Re}(T) \leq T_{BKT}$ and $\mathfrak{Re}(T) > T_{BKT}$ in the thermodynamic limit show that $\mathfrak{Im}(T)$ goes to zero in the former case and is finite in the last one.

Social Capital and the Functioning of Welfare Systems

Publisher: name: QuiEdit
Year: 2015
Subjects: welfare system; social capital; social expenditures

description: The object of this paper is a reflection on the role that social capital can play in the processes of innovation and reform of the welfare system. The analysis is based on the following assumptions: 1. global society requires  higher levels of trust, but has no systems involving unfair sentencing of ; 2. the processes of individualization require high levels of social capital, but are not able to regenerate it; 3. growing inequality, together with the reduction of the redistributive welfare systems, not only makes people 'less equal', but also less 'trusty'. The complex society requires a lot of social capital at macro and micro level, but does not seem able to produce it. In the analysis of  the welfare system, social capital is inserted as a new intervening variable that, depending on the perspective, it is considered as a condition for the proper functioning of the system or as a result of its proper functioning. The social capital may be defined as a set of resources (material and non-material) embedded in the structure of relationships of trust and solidarity. In relation to the functioning of the welfare system, social capital, from a macro perspective, it can be identified with forms of action structures of civil society; from the standpoint of micro, as structures of interpersonal relationships (networks) based on trust and solidarity. To examine the role that social capital can play in the reform of the welfare system, it is necessary to overcome the dichotomies of micro-and macro, cause and effect, and consider the welfare state as an institution that incorporates within it the function of production and consumption of the social capital.

description: A methodology of science must satisfy two requirements: (i) It must be ampliative: the theories which it generates must make statements that go far beyond any data or observations that may have motivated those theories in the first place. (ii) It must be epistemically probative: it must somehow provide a warrant for believing that the theories so produced are correct, or at least partially correct, even if they can never be fully confirmed. These two requirements pull in opposite directions, and attempts to specify the “scientific method” often focus on one to the exclusion of the other. On a few points there now exists something approaching a consensus. (i) Scientific hypotheses — including, particularly, statements about unobserved or unobservable entities or mechanisms — remain conjectural, no matter how frequently predictions based on those hypotheses are found to coincide with data. (ii) A good (best?) indicator of a theory’s verisimilitude is its ability to successfully predict phenomena which it was not specifically designed to predict. I discuss these ideas with particular reference to cosmological theories.

description: 1. The coding sequence of the P2Y1-purinoceptor was cloned from a human genomic library. 2. The open reading frame encodes a protein of 373 amino acids that is 83% identical to the previously cloned chick and turkey P2Y1-purinoceptor and is > or = 95% homologous to the recently cloned rat, mouse, and bovine P2Y1-purinoceptors. 3. The human P2Y1-purinoceptor was stably expressed in 1321N1 human astrocytoma cells using a retroviral vector. Although the P2Y1-purinoceptor agonist, 2MeSATP, had no effect on inositol phosphate accumulation in cells infected with the P2Y1-purinoceptor virus. No effect of 2MeSATP on cyclic AMP accumulation was observed in P2Y1-receptor-expressing 1321N1 cells. 4. The pharmacological selectively of 18 purinoceptor agonists was established for the expressed human P2Y1-purinoceptor. 2MeSATp was more potent than ATP but less potent than 2MeSADP. ADP also was more potent than ATP. A similar maximal effect was observed with most agonists tested. However, alpha, beta-MeATP had no effect and 3'-NH2-3'-deoxyATP and A2P4 were partial agonists. The order of potency of agonists for activation of the turkey P2Y1-purinoceptor, also stably expressed in 1321N1 cells, was identical to that observed for the human P2Y1-purinoceptor. 5. C6 glioma cells express a P2Y-purinoceptor that inhibits adenylyl cyclase but does not activate phospholipase C. Expression of the human P2Y1-purinoceptor in C6 cells conferred 2MeSATP-stimulated inositol lipid hydrolysis to these cells. The phospholipase C-activating human P2Y1-purinoceptor could be delineated from the endogenous P2Y-purinoceptor of C6 glioma cells by use of the P2-purinoceptor antagonist, PPADS, which blocks the P2Y1-purinoceptor but does not block the endogenous P2Y-purinoceptor of C6 cells. P2-purinoceptor agonists also exhibited differential selectivities for activation of these two P2Y-purinoceptors.

Subjects: : welfare systems; local welfare; k-mean cluster analysis

description: The reforms of welfare systems, which happened in different countries, have generated more differences at the local authority, thus the improvement of welfare organization has followed specific development methods providing different services for the citizenship living in the same country. The welfare classification research at cross-national level have not considered the heterogeneity of national welfare system, as underlined by Bertin’s (2012b) research, based on an Italian case study, which identified that the Italian welfare system could be classify in seven different welfare regimes. Thus, this analysis, using the same data of Bertin’s (2012b) analysis and applying a different cluster analysis method (K-mean), attempts to confirm the Bertin’s (2012b) classification. The results corroborate some models of welfare systems identified by previous research but other cluster groups suggest that it is useful to conduct deep analysis in order to distinguish some more welfare system features.

description: 1. The functional activity of deoxyadenosine 5'(alpha-thio)triphosphate (dATP alpha S) was assessed at the cloned human P2Y1 receptor stably expressed in 1321N1 human astrocytoma cells and transiently expressed in Cos-7 cells. 2. Cells expressing the receptor responded to adenine nucleotides with an increase in [3H]-inositol phosphate accumulation. Half-maximal responses were obtained at approximately 30 nM for 2-methylthioadenosine-5'-triphosphate (2MeSATP), 300 nM for dATP alpha S, and 1000 nM for adenosine 5'-triphosphate (ATP). dATP alpha S produced a maximal response that was only 37 +/- 4% of that produced by ATP or 2MeSATP. dATP alpha S also competitively antagonized the phospholipase C response to 2MeSATP with a KB of 644 +/- 14 nM. Thus dATP alpha S acts as a low potency partial agonist at P2Y1 receptors. 3. The selectivity of dATP alpha S for P2Y1 receptors was determined by examining its capacity to activate P2Y2, P2Y4 and P2Y6 receptors also stably expressed in 1321N1 cells. Although dATP alpha S was a partial agonist at P2Y1 receptors it was a full agonist at P2Y2 receptors, albeit with a potency that was two orders of magnitude lower than at P2Y1 receptors. No agonist or antagonist activity was observed at P2Y4 and P2Y6 receptors. 4. Although [35S]-dATP alpha S bound to a relatively high density (ca 10 pmol mg-1 protein) of binding sites in membranes from 1321N1 or Cos-7 cells expressing the P2Y1 receptor, no difference in the total density of sites was observed between membranes from wild-type, empty vector-transfected, or P2Y1 receptor-expressing cells. Moreover, adenine nucleotide analogues inhibited [35S]-dATP alpha S binding with an order of potency that differed markedly from that for the accumulation of inositol phosphates in intact transfected P2Y1 receptor-expressing cells. Saturation binding experiments demonstrated multiple affinity states for [35S]-dATP alpha S binding in wild-type Cos-7 cell membranes. These data from 1321N1 and Cos-7 cells suggest that cellular membranes exhibit a large number of high affinity binding sites for [35S]-dATP alpha S that are not related to P2Y receptor subtypes.

description: Animal coloration has traditionally been the target of genetic and evolutionary studies. However, until very recently, the study of the genetic basis of animal coloration has been mainly restricted to model species, whereas research on non-model species has been either neglected or mainly based on candidate approaches and thereby limited by the knowledge obtained in model species. Recent high-throughput sequencing technologies allow us to overcome previous limitations, and open new avenues to study the genetic basis of animal coloration in a broader number of species and colour traits, and to address the general relevance of different genetic structures and their implications for the evolution of colour. In this review, we highlight aspects where genome-wide studies could be of major utility to fill-in the gaps in our understanding of the biology and evolution of animal coloration. The new genomic approaches have been promptly adopted to study animal coloration although substantial work is still needed to consider a larger range of species and colour traits, such as those exhibiting continuous variation or based on reflective structures. We argue that a robust advancement in the study of animal coloration will also require large efforts to validate the functional role of the genes and variants discovered using genome-wide tools.This article is part of the themed issue ‘Animal coloration: production, perception, function and application’.

description: The relationship between human beings and landscape/place is an issue that cuts across human communities. However, even before it is formulated as a question, the landscape and what constitutes it reveal themselves as the very possibility of orientating ourselves in the world, of recognising meaning in it - before taking the landscape as an object of reflection, the landscape is always already an existential condition of the human being. Starting from this premise, the anthropologist must try to understand how different cultures articulate their 'answers' to the same question - the nature of the human-landscape relationship - and harmonise them with his/her own 'answers'. However, both inside and outside anthropology, many of the answers that have been given belong to a different type of question: questions that presuppose, from the outset, a human subject who is in opposition to the world, making judgements about it, attributing functions and properties to it. As a result, the landscape often becomes an object that we try to define or determine the conditions of perception/access to. For this talk, I will start by illustrating this objectifying tendency as I go through some of the literature on landscape. Then, in a second moment, I will try to elaborate a possible 'answer' that Japanese culture seems to articulate to the initial question (the nature of the human-landscape relationship). This 'answer', in turn, will include a reflection on (i) 'nature' in Japanese culture and (ii) the Japanese notion of 'furusato' ('native village' / 'native place') in its cultural, philosophical and ethnographic dimensions. The overall purpose of this talk lies in the possibility of taking this 'answer' as our own, reflecting on its human dimension and not just the cultural one.
The Invisible Interviewer: Old and New Methodological Issues in Online Research

Subjects: web interviewing; online research; web survey

description: Over the last two decades, computer-mediated and online research methods have been gaining ground over traditional data collection tools for research. As a consequence, the role of the interviewer is affected. In this article, the visibility or invisibility of  the interviewer is used to express the degree of control that the interviewer has in the interviewing process. For example, the interviewer has full control in face-to-face interviews, but this control decreases as the interviewer's level of visibility decreases, such as in phone interviews, and is nullified when the interviewer is missing entirely, such as in self-administered surveys on the web. This raises the question of how the visibility of the interviewer is currently surrogated and how the solutions adopted in social research may be suitable for describing the corresponding impact of digital technologies on social life. In concluding, possible scenarios of new digitally mediated solutions of data collection are presented. These scenarios take also into consideration data treatment technologies and their capacity to control the enormous amount of material that digitally mediated social life has produced.
