Theoretical uncertainty in baryon oscillations

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We discuss the systematic uncertainties in the recovery of dark energy properties from the use of baryon acoustic oscillations as a standard ruler. We demonstrate that while unknown relativistic components in the universe prior to recombination would alter the sound speed, the inferences for dark energy from low-redshift surveys are unchanged so long as the microwave background anisotropies can measure the redshift of matter-radiation equality, which they can do to sufficient accuracy. The mismeasurement of the radiation and matter densities themselves (as opposed to their ratio) would manifest as an incorrect prediction for the Hubble constant at low redshift. In addition, these anomalies do produce subtle but detectable features in the microwave anisotropies.

subject: FOS: Mathematics

description: Based on stochastic differential equations (SDEs), we analyse the overall performance of heterogeneous power systems network, subject to spatially distributed and correlated noise with random initial conditions. We determine bounds on the H_2 norm of the heterogeneous system based on a closed-form of the norm of the homogeneous power system. Then, we formulate possible scenarios for performance optimization and link these to applications for network design and control problems in power systems. Our results are corroborated by numerical simulations from Kundur's four-machine two-area network after adaption to our setup.

description: We propose a new theoretical interpretation of the electron energy-loss spectroscopy results of Pichler {\it et al.} on bulk carbon nanotube samples. The experimentally found nondispersive modes have been attributed by Pichler {\it et al.} to interband excitations between localized states polarized perpendicular to the nanotube axis. This interpretation has been challenged by a theorist who attributed the modes to optical plasmons carrying nonzero angular momenta. We point out that both interpretations suffer from difficulties. From our theoretical results of the loss functions for individual carbon nanotubes based on a tight-binding model, we find that the nondispersive modes could be due to collective electronic modes in chiral carbon nanotubes, while the observed dispersive mode should be due to collective electronic modes in armchair and zigzag carbon nanotubes. Momentum-dependent electron energy-loss experiments on individual carbon nanotubes should be able to confirm or disprove this interpretation decisively.

description: Many Higher Education Institutions in India have started to include Massive Open Online Course (MOOC) as a part of their curriculum. Yet little research has been done to understand the factors that affect the users’ sustained interest to recurrently enroll and complete MOOC courses throughout their lifetime. A sample of 316 students from Higher Education Institutes in India participated in this survey. Partial Least Square Structural Equation Modeling (PLS-SEM) using smartPLS was employed to assess the structural model. The structural model used is a combination of constructs from technology acceptance theories namely perceived usefulness, perceived ease of use, attitude, facilitating condition and continuous use intention of MOOCs, with perceived reputation and MOOCs self-efficacy as external variables. The results not only proved the applicability of basic TAM constructs in understanding the behavioral intention of MOOCs but also the significance of external variables, particularly the role of perceived reputation in influencing the perceived usefulness of MOOCs.

description: L’objet de cet article est de tester l’hypothèse selon laquelle l’intensité de la concurrence fiscale est plus forte en milieu urbain qu’en milieu rural. Dans ce but, nous construisons un modèle spatial de choix fiscal communal qui tient compte des choix fiscaux des communes concurrentes en matière de taxe professionnelle. Plus particulièrement, nous testons l’hypothèse de l’existence d’interactions fiscales au sein de différents groupements intercommunaux et nous en mesurons la forme et l’intensité à l’aide des techniques d’économétrie spatiale. Nous relions ensuite ces mesures d’intensité aux caractéristiques de l’aire étudiée, en particulier à son statut dans le zonage en aires urbaines et en aires d’emploi de l’espace rural (ZAU-ER). Nous concluons à l’existence d’interactions fiscales entre les communes appartenant à l’espace à dominante urbaine. En revanche, l’hypothèse d’interactions fiscales horizontales n’est pas vérifiée dans les communes appartenant à l’espace à dominante rurale.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.

description: La réforme de la Politique agricole commune (PAC), décidée par le Conseil européen en juin 2003, modifie le mode d’intervention des pouvoirs publics au sein de l’agriculture européenne. En France, la mise en oeuvre d’un paiement unique découplé en substitution d’une partie des paiements compensatoires alloués historiquement sur la base des facteurs de production constitue une rupture importante, notamment dans le secteur bovin (lait et viande bovine). L’objectif de cet article est de mesurer les conséquences de cette réforme de la PAC sur l’évolution, à l’horizon de 2007, des aides directes et du paiement unique dans différentes catégories d’exploitations laitières et bovins-viande françaises. La simulation, qui est conduite sur la base des données individuelles du Réseau d'information comptable agricole (RICA) de l’exercice 2003, prend en compte des hypothèses de gains de productivité et traite de deux options de découplage : partiel (au sens des modalités retenues en France) et total (comme la réglementation communautaire le permet). Sur la base de la situation projetée, une discussion est ensuite engagée sur les possibilités offertes aux États membres d’une éventuelle redistribution des soutiens directs. Ce travail permet de souligner les principaux points suivants : le revenu de la très grande majorité des exploitations bovines deviendra, au terme de la réforme, fortement dépendant des soutiens directs ; le dispositif de modulation concernera plus de 95% des exploitations bovines ; le montant du paiement unique (rapporté à l'exploitation, à l’hectare ou aux résultats économiques) variera fortement selon la taille de l’exploitation, son système productif historique et son niveau d’intensification ; le principe de la régionalisation du paiement unique (articles n° 58 et 59 du règlement n° 1782) conduit, dans une région administrative donnée, à un transfert de soutiens directs des unités les plus intensives vers les unités les plus extensives, mais ne permet pas d’opérer, comme c’est le cas de l’article n° 69, une redistribution de fonds entre régions.

description: A novel and efficient heterogeneous gold(I)-catalyzed three-component reaction of aldehydes, alkynes, and orthoformates has been developed that proceeds smoothly in dichloroethane (DCE) at 83 °C in the presence of 5 mol% magnetic nanoparticles-anchored phosphine gold(I) complex (Fe3O4@SiO2-P-AuOTf) and offers a general and practical approach for the preparation of a variety of propargyl ethers with good yields. This heterogeneous gold(I) catalyst can be facilely recovered by simply applying an external magnetic field and recycled at least eight times without any apparent decrease in the catalytic efficiency.

description: Bursts of localized star formation in galaxies can levitate material from their midplanes. Spiral galaxies that are edge-on allow clear distinction of material that is levitated off the galaxies' midplanes. We used SOFIA to measure the vertical distribution of [C II] 157.7 micron line emission for two nearby, edge-on galaxies, NGC 891 and NGC 5907. We find that for the central region and actively-star-forming regions in the northern portion of NGC 891, and for NGC 5907, a thin (0.3 kpc) disk is supplemented by a thick disk with an exponential scale height of about 2 kpc. The [C II] is far more extended than mid-infrared emission (0.1 kpc, tracing present-day massive star formation) but not as extended as the H I (100 kpc, tracing low-metallicity circum/inter-galactic matter). The extraplanar [C II] may arise in walls of chimneys that connect the disk to the halo.

description: This thesis aims to investigate the advantages and limitations of starting up a business in Europe and the United States. This paper contributes to the discourse of where an entrepreneur will find the most suitable location for his or her business. In order to answer the research questions presented on this paper, a qualitative, exploratory and abductive methodology was chosen as appropriate. This thesis draws on findings from the field as well as academic papers. The author of this paper selected three major ways of gathering data: a 15-question survey given out to entrepreneurs and employees of SMB organizations, many in-depth semi-structured interviews with seven entrepreneurs and finally, complemented by literature research from studies, articles, books and other academic sources. The findings show that there are many factors that affect the rate at which entrepreneurs start and grow a business. On this study, a deep-down analysis is performed of each of the most repeated patterns and broken down into two categories, “Major” and “Minor” factors, an order given by a ranking that was provided by the interviewees and survey respondents. By analyzing the most important business-related aspects of each territory, based on quantitative data from each region the hope is the reader can build a model to choose which territory would work best for his or her specific scenario.

description: Our study makes an analysis of American’ multinationals foreign market entry strategies in the European Union agribusiness context. We have used a logistic regression analysis using generalized estimating equation method to make hypothesis about the multinationals’ choices. Our results suggest that American food companies operating in EU appear not to choose their mode of entry based merely on host country factors, but mostly on firm related factors, including firm-specific factors and firm financial performance. Despite the creation of a common institutional framework for M&As in the EU, they are still subject to peculiarities due mostly to organizational characteristics of investing firms.
Democracy by regions : emergence and development of a regime to protect democracy in the Americas
Creators: name: Franco Franco, Rodolfo
Publisher: name: University of British Columbia
Year: 2010

description: Recently regional organizations in Africa and the Americas have developed mechanisms to protect and develop democracy among their member states. Crucial to these developments has been the adoption of clauses for the ’collective protection of democracy’. Nevertheless, wide variations in the scope and reach of such mechanisms among regional organizations suggest that the so called ’global norm of democratic governance’ acquires different institutional forms across regions. Institutional developments in the Americas suggest that the norm and practice of defending elected governments within the region has produced particular institutional arrangements. Particular understandings about legitimate governance and legitimate state action within the Inter-American System structure the institutional choices available to states and decision makers within the regional construct. Regions, as are states, are social constructions which produce social realities for those belonging to them, whether states or individuals. It is possible to think of regions as social kinds, which hold an identity and enact certain patterns of interaction that can account for the type of regional arrangements they do (or do not) produce to promote democracy. Regional institutions and the mechanisms they put in place to promote and defend democracy respond to the particular historical and cultural development of each of the regions. The normative structures of the regional systems strongly influence ways in which the states within them decide to promote and develop democracy and the institutional choices they make for this aim.

description: The objective of this study is to assess the existence and magnitude of volatility spillovers between the extra virgin olive oil markets of Italy, Spain and Greece. These three Mediterranean countries are responsible for 95% of olive oil production within the European Union and they account for more than 50% of olive oil exports worldwide. In order to measure the degree of volatility transmission between these countries we estimate a vector error correction model along with the BEKK parameterization of a Multivariate Generalized Conditional Autoregressive Heteroskedasticity (M-GARCH) model. The empirical results reveal the presence of ARCH and GARCH effects suggesting this way the existence of volatility spillovers between the extra virgin olive oil markets of Italy, Greece and Spain. ARCH effects are the biggest in magnitude for the market between Spain and Italy. GARCH effects are the biggest in magnitude for the market between Greece and Italy.

description: We calculate the electromagnetic form factors of a bound proton. The Chiral Quark-Soliton model provides the quark and antiquark substructure of the proton, which is embedded in nuclear matter. This procedure yields significant modifications of the form factors in the nuclear environment. The sea quarks are almost completely unaffected, and serve to mitigate the valence quark effect. In particular, the ratio of the isoscalar electric to the isovector magnetic form factor decreases by 20% at Q^2=1 GeV^2 at nuclear density, and we do not see a strong enhancement of the magnetic moment.

description: We present a measurement of the rate of correlated neutron captures in the WATCHBOY detector, deployed at a depth of approximately 390 meters water equivalent (m.w.e.) in the Kimballton Underground Research Facility (KURF). WATCHBOY consists of a cylindrical 2 ton water target doped with 0.1% gadolinium, surrounded by a 40 ton undoped water hermetic shield. We present a comparison of our results with the expected rate of correlated neutron captures arising from high-energy neutrons incident on the outside of the WATCHBOY shield, predicted by a hybrid FLUKA/GEANT4-based simulation. The incident neutron energy distribution used in the simulation was measured by a fast neutron spectrometer, the 1.8-ton Multiplicity and Recoil Spectrometer (MARS) detector, at the same depth. We find that the measured detection rate of two correlated neutrons is consistent with that predicted by simulation. The result lends additional confidence in the detection technique used by MARS, and therefore in the MARS spectra as measured at three different depths. Confirmation of the fast neutron flux and spectrum is important as it helps validate the scaling models used to predict the fast neutron fluxes at different overburdens.

description: A toy model for gamma-ray burst-supernovae (GRB-SN) is discussed by considering the coexistence of baryon poor outflows from black holes (BHs) and a powerful spin-connection to surrounding disk, giving rise to consistent calorimetry as described by van Putten (2001a) in a variant of the Blandford-Znajek process (BZ, 1977). In this model the half-opening angle of the magnetic flux tube on the horizon is determined by the mapping relation between the angular coordinate on the BH horizon and the radial coordinate on the surrounding accretion disk. The GRB is powered by the baryon poor outflows in the BZ process, and the associated SN is powered by very small fraction of the spin energy transferred from the BH to the disk in the magnetic coupling (MC) process. The timescale of the GRB is fitted by the duration of the open magnetic flux on the horizon. It turns out that the data of several GRB-SNe are well fitted with our model.

description: Agency independence is understood to instil credibility in regulatory policy. This is a core tenet of regulation theory, foundational to the EU regulatory state’s own origin story. We put the assumption to rigorous testing, in addition to expanding on it theoretically. We expect that stakeholder perceptions of credibility depend not only on agencies’ institutional insulation, but also on whether regulatory outcomes are congruent with stakeholders’ prior beliefs and preferences. Focusing on EU food safety regulation and the European Food Safety Authority, we test, observationally and experimentally, whether the credibility of agency scientific outputs is enhanced when stakeholders perceive the agency as more independent. Some support for the theorised link is present observationally, yet we do not find consistent and reliable experimental causal evidence for the purported relationship. We further find that the credibility of agency outputs is greatly influenced by stakeholders’ prior positions on the issue, pointing at persistent contestation. The study advances our understanding of the factors that shape credibility perceptions, supplementing institutional accounts with individual-level considerations, namely the role of priors. Our study indicates independence is a necessary but partial solution in that it can enhance stakeholder perceptions of credibility but does not compensate for the negative effect of priors.
Third order optical nonlinearity of three dimensional massless Dirac fermions

description: We present analytic expressions for the electronic contributions to the linear conductivity $σ^{(1)}_{3d}(ω)$ and the third order optical conductivity $σ^{(3)}_{3d}(ω_1,ω_2,ω_3)$ of three dimensional massless Dirac fermions, the quasi-particles relevant for the low energy excitation of topological Dirac semimetals and Weyl semimetals. Although there is no gap for massless Dirac fermions, a finite chemical potential $μ$ can lead to an effective gap parameter, which plays an important role in the qualitative features of interband optical transitions. For gapless linear dispersion in three dimension, the imaginary part of the linear conductivity diverges as a logarithmic function of the cutoff energy, while the real part is linear with photon frequency $ω$ as $\hbarω>2|μ|$. The third order conductivity exhibits features very similar to those of two dimensional Dirac fermions, i.e., graphene, but with the amplitude for a single Dirac cone generally two orders of magnitude smaller in three dimension than in two dimension. There are many resonances associated with the chemical potential induced gap parameters, and divergences associated with the intraband transitions. The details of the third order conductivity are discussed for third harmonic generation, the Kerr effect and two-photon carrier injection, parametric frequency conversion, and two-color coherent current injection. Although the expressions we derive are limited to the clean limit at zero temperature, the generalization to include phenomenological relaxation processes at finite temperature is straightforward and is presented.

description: In the recent past, the Kenyan economy experienced persistent inflationary pressures, partly attributed to food price spikes. However, the quantitative role of food prices in inflation is not well understood or formally empirically analyzed in Kenya yet food occupies a weight of 36 percent in the consumer price index and contributes a monthly average of over 40 percent to overall inflation. Based on monthly data covering the period 1997-2012, this paper attempts to fill this gap by examining the relationship between food prices and inflation. The study used gap models and Phillips curve approaches to estimate the passthrough effects of food prices to both overall inflation and non-food non-fuel inflation. Based on gap models, the results confirm presence of second round effects from food prices to inflation while estimations of the Phillips curve suggest a domestic food price pass-through of 0.49 to overall inflation and 0.38 to non-food non-fuel inflation. The world food prices pass-through to overall inflation and non-food non-fuel inflation are estimated at 0.09 and 0.08, respectively. Thus this paper recommends usage of headline inflation to estimate trend inflation, enhanced communication to mitigate second round effects and that while monetary policy is very critical in anchoring inflationary expectations, there is mutual gain from a supportive fiscal policy in addressing supply side shocks.

description: In this paper, we develop a resource allocation framework to optimize the downlink transmission of a backhaul-aware multi-cell cognitive radio network (CRN) which is enabled with multi-carrier non-orthogonal multiple access (MC-NOMA). The considered CRN is composed of a single macro base station (MBS) and multiple small BSs (SBSs) that are referred to as the primary and secondary tiers, respectively. For the primary tier, we consider orthogonal frequency division multiple access (OFDMA) scheme and also Quality of Service (QoS) to evaluate the user satisfaction. On the other hand in secondary tier, MC-NOMA is employed and the user satisfaction for web, video and audio as popular multimedia services is evaluated by Quality-of-Experience (QoE). Furthermore, each user in secondary tier can be served simultaneously by multiple SBSs over a subcarrier via Joint Transmission (JT). In particular, we formulate a joint optimization problem of power control and scheduling (i.e., user association and subcarrier allocation) in secondary tier to maximize total achievable QoE for the secondary users. An efficient resource allocation mechanism has been developed to handle the non-linear form interference and to overcome the non-convexity of QoE serving functions. The scheduling and power control policy leverage on Augmented Lagrangian Method (ALM). Simulation results reveal that proposed solution approach can control the interference and JT-NOMA improves total perceived QoE compared to the existing schemes.

description: The blockchain and the Internet of Things (IoT) are emerging technologies. The blockchain can be described as a public, distributed ledger, which is built on a peer-to-peer (P2P) network. The IoT is an interconnection of sensing and actuating devices where information can be shared across platforms. Generally, it can be said that these two technologies operate in different application fields. However, the blockchain has the potential to solve challenges of the IoT. Despite of the popularity, the amount of approaches to use the blockchain in the IoT is limited. Additionally, the existing approaches focus on basic questions instead of using the blockchain technology in more complex applications. Thus, this thesis deals with the question how to use the blockchain in the IoT from a software engineering perspective. During the course of this thesis we design and implement the blockchain-IoT application which uses Ethereum. The application is able to collect data from sensors and distribute the data via two communication channels. The core of the application is a middleware which connects a sensor driver that collects the sensor data with clients that subscribe to the different communication channels. Furthermore, the IoT client is implemented which is able to monitor the delays of both communication channels and which tracks relevant information of the blockchain for the final evaluation. The developed application is evaluated on three different IoT devices, namely on an Intel Galileo Gen2, an Odroid-XU4 and a Raspberry Pi 3. One result of this thesis is the blockchain-IoT application and the IoT client. The whole framework is able to collect data from sensors and distribute it via a real-time channel and a channel with guaranteed integrity. Additionally, the IoT client is able to monitor the delays of both channels and the confirmation times of transactions in Ethereum. The evaluation results show that enabling Ethereum on the Intel Galileo Gen2 is not feasible. The setup of the developed application on the other devices is possible. However, different workloads show that the portability of the application is restricted. The best performance in terms of message losses is achieved on the Raspberry Pi 3.

description: The main objectives of this master thesis are to identify and analyze how the startup founders role changes during startup development and which factors drive these changes. After the review of available international literature, the interview method was chosen to receive a deep insight into the founders role development in tech startups. Interviews with founders in Europe and US were conducted, which showed that founders see their roles development as evolutional, but full of challenges. An empirical study confirmed that the acquisition of human, social and financial capital requires the attention of founders and balancing with multiple priorities. Hiring, delegation and building a culture within the team were emerging issues for the founders. They devote significant part of their time to those activities and sometimes even change the way of doing things and how they communicate with the team. The biggest supporters in those challenges were the founders own experience and advice from the founders community. Therefore, networking was identifies as an important driver for the founders development.

description: Fiscal preferences of populist radical right parties (PRRPs) typically entail a combination of lower tax rates and the maintenance of costly social spending categories, such as pension spending. Theoretically, this combination is doomed to inflate future public liabilities. In our mixed method study, we assess whether PRRPs in government indeed systematically cause higher deficits and to what extent the combination of tax and social policy explains their public finance. We theoretically discuss the evolution of tax policy and welfare preferences of PRRPs and contend that radical right fiscal preferences are driven by PRRPs’ ideological core claim of ‘native producerist deservingness’. Based on mixed effects models with entropy balanced weights, we show that PRRPs in government have significantly and substantially higher public deficits than governments without PRRPs and similar socio-economic starting conditions. This effect, however, is different in Eastern Europe, where PRRPs in government produce comparatively lower deficits, albeit signalling and implementing the same policy-mix as Western PRRPs. We trace the causes of the differences in outcome with an in-depth case study of the Fidesz government in Hungary from 2010 to 2014.

description: To enhance the skin whitening effect, tyrosinase activity and melanin biosynthesis needs to be suppressed in the skin. To achieve this goal, we examined the extract of Thymus quinquecostatus flowers, and identified a functional ingredient, galuteolin. Galuteolin effectively inhibited melanin biosynthesis in B16/F10 cells, partially suppressing tyrosinase activity. Therefore, this study suggests that galuteolin can be used as a cosmetic ingredient for skin whitening.

description: The role of SMEs for driving innovation in different industries is an essential element nowadays for the economic activity. To remain competitive in this changing environment it is necessary to have an alignment between the business strategy, levels of innovation and management decisions. There are sufficient evidences that we are in the midst of a paradigm change in terms of innovation drivers. We cannot consider firm size and financial capital as relevant as in the past since the boundaries of the firm cannot be clearly defined anymore due to complex alliances, collaboration, cooperation and other forms of open innovation models and structures alike in place. This way, the primary source of competitive advantage has shift from a financial capital centric one to another where knowledge and information are more relevant. The purpose of this study is to analyze the collaboration options and strategy fit in the actual and upcoming context of telecommunications industry SMEs. In the initial part of the paper are introduced different concepts used in the thesis to provide an academically background to address the research questions that conform the thesis. The concept of Open Innovation and the different collaboration taxonomy frameworks are used to better understand distinct collaboration ‘flavors. To analyze the strategic fit, the concept of Value Network is presented in the pater. Finally, we have introduced a categorization of innovation levels relevant in order to leverage innovation processes. The following section of the paper describes the exploratory approach of this research, based on several interviews with managers that have been working in the ICT and telecommunications industry. These professionals have faced collaborations in one or another stage of their careers. The structure of the interviews is conceived to identify changes in the industry and technologies that have had an impact on the collaboration as a phenome in the past. The answers of the participants have been analyzed using the theoretical background introduced in the initial part of the 5 | P a g e document to answers the research questions. The final part of the paper addresses future directions and expected changes and challenges in order to adapt the collaboration strategy to the always-changing.
Algebraic approach and Berry phase of a Hamiltonian with a general $SU(1,1)$ symmetry

description: In this paper we study a general Hamiltonian with a linear structure given in terms of two different realizations of the $SU(1,1)$ group. We diagonalize this Hamiltonian by using the similarity transformations of the $SU(1,1)$ and $SU(2)$ displacement operators performed to the $su(1,1)$ Lie algebra generators. Then, we compute the Berry phase of a general time-dependent Hamiltonian with this general $SU(1,1)$ linear structure.

description: International trade theory suggests that advanced trade integration may lead to higher levels of intra-industry trade (IIT). The enlargement of the European Union (EU) during last decade is as a good example for which to analyse the IIT in agri-food products. The aim of the paper is to analyse the pattern and drivers of horizontal IIT within the EU between 1999 and 2010. Previous empirical studies fail to provide an exact link between the theory and the data. Thus, a new empirical strategy developed to test the predictions of Helpman and Krugman (1985) model is employed. At the country level, Belgium, France, Netherlands and Germany report the highest levels of IIT within the EU. The calculations mainly support Cieslik’s (2005) proposal to find the missing link between empirics and theory of IIT. In addition, the results are robust to alternative subsamples.

description: Introduction: The variant NEGR1 rs2815752 has recently been linked with obesity in Caucasians. However, a very limited number of studies have examined the association of the NEGR1 rs2815752 with overweight/obesity in non-Caucasians with no such study ever performed in Pakistani population. Therefore, the present study was undertaken to seek the association of the rs2815752 with overweight, obesity, and related traits in Pakistanis. Subjects and methods: The study involved 112 overweight/control pairs (total 224) and 194 obese/control pairs (total 388). Anthropometric parameters were measured by employing standard procedures. Metabolic parameters were determined by biochemical assays. Behavioral information was collected through a questionnaire. The rs2815752 was genotyped via TaqMan allelic discrimination assay. Regression analyses were employed to analyze the data in SPSS software. Results: The study revealed significant gender-specific association of the rs2815752 with obesity (OR 3.03; CI 1.19–7.72, p = 0.020) and some obesity-related anomalous anthropometric traits (weight, BMI, waist circumference, hip circumference, and abdominal and supra-iliac skinfold thicknesses) in females according to dominant model (h = 0.023). However, no association of the rs2815752 with obesity-related behavioral and metabolic parameters was observed. Conclusion: The NEGR1 rs2815752 may be associated with obese phenotype and some of the related anthropometric traits in Pakistani females.

description: The new ECB leadership made it its explicit priority to make ECB’s policies greener. Although doubt remains about the scale and effectiveness of the policies implemented since then, the idea that the ECB has a role to play in the fight against climate change has become widely accepted. The main narrative in support of this idea states that the ECB’s pro-climate engagement is part of its primary mandate – price stability. However, until not long ago, ECB’s primary mandate was rather used by those opposing the greening of central banking, while it was largely ignored by pro-climate advocates. How has this narrative emerged and gained traction? This paper argues that this narrative results from a process of coalition-building between pro-climate central bankers and pro-climate politicians in the European Parliament. Building on a multi-method text analysis of original datasets of accountability communications as well as in-depth interviews, this paper documents the mechanisms through which pro-climate central bankers and pro-climate MEPs co-constructed the pro-climate narrative, using accountability relationships as a coalition-building arena. The paper contributes to ongoing discussions on central banks’ accountability, politicisation and role in the green transition.
