description: Purpose: Buying behaviour can be interpreted as a signal of social identity. For example, individuals may purchase specific cars to indicate their social status and income, or they may dress in particular ways to show their taste in fashion or their membership in a social group. This paper aims to focus on the identification of market place influencers in a social identity context, in order to better market products and services to social groups. Design/methodology/approach: A structural model linking consumers' individual capital (motivation to influence), social capital (opportunistic use of social influence), and social leadership ability (persuasive "power") is introduced. Hypotheses on the interrelations of these factors are proposed and the model is empirically tested using causal analysis. The survey data were collected in Germany in the context of socially influenced automotive buying behavior (428 valid questionnaires). Findings: The proposed model supports significant relations between individual capital and social capital and social leadership ability. The results suggest which factors (individual and social capital) describe social influencers, helping to identify powerful social influencers in a social identity context. Different types of social influence leaders and followers are presented and characterized. Originality/value: This paper offers marketing researchers and practitioners a new integrative approach to target consumers with specific social identities via social influencers. © Emerald Group Publishing Limited.
Impact of a low-energy enhancement in the gamma-ray strength function on the radiative neutron-capture

description: A low-energy enhancement of the gamma-ray strength function in several light and medium-mass nuclei has been observed recently in 3He-induced reactions. The effect of this enhancement on (n,gamma) cross-sections is investigated for stable and unstable neutron-rich Fe, Mo and Cd isotopes. Our results indicate that the radiative neutron capture cross sections may increase considerably due to the low-energy enhancement when approaching the neutron drip line. This could have non-negligible consequences on r-process nucleosynthesis calculations.

description: Semichiral sigma models with a four-dimensional target space do not support extended N=(4,4) supersymmetries off-shell arXiv:0903.2376, arXiv:0912.4724. We contribute towards the understanding of the non-manifest on-shell transformations in (2,2) superspace by analyzing the extended on-shell supersymmetry of such models and find that a rather general ansatz for the additional supersymmetry (not involving central charge transformations) leads to hyperkähler geometry. We give non-trivial examples of these models.

Solar Irradiance Variability

Year: 2012
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: The Sun has long been considered a constant star, to the extent that its total irradiance was termed the solar constant. It required radiometers in space to detect the small variations in solar irradiance on timescales of the solar rotation and the solar cycle. A part of the difficulty is that there are no other constant natural daytime sources to which the Sun's brightness can be compared. The discovery of solar irradiance variability rekindled a long-running discussion on how strongly the Sun affects our climate. A non-negligible influence is suggested by correlation studies between solar variability and climate indicators. The mechanism for solar irradiance variations that fits the observations best is that magnetic features at the solar surface, i.e. sunspots, faculae and the magnetic network, are responsible for almost all variations (although on short timescales convection and p-mode oscillations also contribute). In spite of significant progress important questions are still open. Thus there is a debate on how strongly irradiance varies on timescales of centuries (i.e. how much darker the Sun was during the Maunder minimum than it is today). It is also not clear how the solar spectrum changes over the solar cycle. Both these questions are of fundamental importance for working out just how strongly the Sun influences our climate. Another interesting question is how solar irradiance variability compares with that of other cool dwarfs, particularly now that observations from space are available also for stars.

Compressible Air Entrapment in High-Speed Drop Impacts on Solid Surfaces

Year: 2012
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: Using high-speed photography coupled with optical interference, we experimentally study the air entrapment during a liquid drop impacting a solid substrate. We observe the formation of a compressed air film before the liquid touches the substrate, with internal pressure considerably higher than the atmospheric value. The degree of compression highly depends on the impact velocity, as explained by balancing the liquid deceleration with the large pressure of compressed air. After contact, the air film expands vertically at the edge, reducing its pressure within a few tens of microseconds and producing a thick rim on the perimeter. This thick-rimmed air film subsequently contracts into an air bubble, governed by the complex interaction between surface tension, inertia and viscous drag. Such a process is universally observed for impacts above a few centimeters high.

description: Purpose: Over the last few decades, corporate social responsibility (CSR) has received a large amount of attention in research and in practice. As a response to the growing awareness of and concern about social and environmental issues, an increasing number of companies are proactively publishing their CSR-related principles and activities. The overall research question of this study is derived from legitimacy theory and is aimed at elucidating the relationship between industry sector and CSR communication. The paper aims to discuss these issues. Design/methodology/approach: The empirical examination encompasses a sample that includes the annual reports of all German DAX-30 companies from 1998 to 2009. First, based on a content analysis, categories of CSR-related communication are defined. Second, these categories are used in a quantitative analysis with a longitudinal perspective to evaluate the hypothesis that companies in controversial industries communicate their CSR more intensely than companies in non-controversial industries. Findings: The qualitative study leads to a category system that accounts not only for CSR-related activities but also for CSR philosophies and motives as the normative basis of CSR communication. The quantitative results support the hypothesis that companies in controversial industries are more active in CSR communication than companies in non-controversial industries. Originality/value: Existing studies analysing CSR communication activity have been largely inconsistent and often use unsystematic approaches in choosing industries for comparison. Therefore, in this study, to overcome some of these deficiencies, a combination of quantitative and qualitative approaches addresses the concept of controversial industries. © Emerald Group Publishing Limited.

description: We have investigated the spontaneous polarization in Fe$_3$O$_4$ thin films by using dynamic and static pyroelectric measurements. The magnetic and dielectric behavior of Fe$_3$O$_4$ thin films grown on Nb:SrTiO$_3$(001) substrates was consistent with bulk crystals. The well-known metal-insulator (Verwey) transition was observed at 120 K. The appearance of a pyroelectric response in the Fe$_3$O$_4$ thin films just below the Verwey temperature shows that spontaneous polarization appeared in Fe$_3$O$_4$ at the charge ordering transition temperature. The polar state characteristics are consistent with bond- and site- centered charge ordering of Fe$^{2+}$ and Fe$^{3+}$ ions sharing the octahedral $B$ sites. The pyroelectric response in Fe$_3$O$_4$ thin films was dependent on the dielectric constant. Quasi-static pyroelectric measurement of Pd/Fe$_3$O$_4$/Nb:SrTiO$_3$ junctions showed that magnetite has a very large pyroelectric coefficient of 735 nC/cm$^{2}$K at 60 K.

description: Purpose-A deeper understanding of the key drivers of consumer wine perception is a major challenge in the domain of wine marketing. The purpose of this paper is to examine the various dimensions of customer-perceived value that lead the customers-in general and divided into different age groups-to choose and consume a certain wine. Design/methodology/approach-In the exploratory study context of examining value-related consumer attitudes and behavioural effects, the drivers and outcomes of wine consumption based on a cross-generation sample, PLS path modelling was considered for the empirical tests of our hypotheses. Findings-Though there exist differences between Generation X and Generation Y consumers, the empirical results are supportive of the hypothesized positive relations between financial, functional, individual and social perceptions that influence the desire for and the consumption of wine. Research limitations/implications-For future research, the findings presented in the paper support the importance of enlarging the size of the sample and collecting data in different countries to compare the results on an international level. Practical implications-Successful wine marketing strategies should focus on the customer’s subjective expectations and individual value perceptions by addressing the specific value aspects that are highly relevant for consumer loyalty. Originality/value-The study results are valuable for researchers, managers and marketers because they address the question of how to measure and forecast the perceived value with the greatest influence on consumers’ wine choices. © Emerald Group Publishing Limited.
Tasting green: An experimental design for investigating consumer perception of organic wine

description: Purpose: There is empirical evidence that the image of organic products has a stronger effect on consumer perception than the intrinsic characteristics. Against this background, the aim of this paper is twofold; first, to ascertain if the stimulus "organic food", placed by storytelling, influences the perception of wine. Based on this, the study tries to discover wherein a positive perception of organic wine might be reflected (e.g. willingness to pay premium prices, better taste perception). Design/methodology/approach: Focusing on the consumer perception and evaluation of conventional versus organic wine, it was decided to use an experimental design with a blind taste test procedure. The prediction was that subjects would rank a wine described as organic higher than a conventional wine - even if there is no objective difference. Consumer perceptions and attitudes toward the wines were assessed using a questionnaire including wine preference, buying and recommendation intention, and willingness to pay. Besides, consumer wine knowledge and consumer personal environmental orientation were measured as individual constructs. Findings: In accordance with existing research insights, consumers tend to prefer organic products over conventional ones. In this context, the experiment shows that adding information on the product's process during a blind test leads consumers to increase their ratings in favour of the "organic wine". Interesting is that consumers even give a better rating for "conventional wine" just described as being "organic", indicating that the appearance and taste are perceived to be better, and the price intention is higher - thus, a pure signalling effect is achieved. Originality/value: The key finding of the study was that even if they tasted the identical product, the respondents ascribe a significantly better taste to the organic-labelled wine compared to the conventional alternative. Besides, the willingness to recommend the organic wine and the willingness to pay differed significantly from the evaluation of the red wine presented as "conventional". Moreover, regardless of their knowledge and attitude towards organic products in general, all respondents rated the so-called organic wine higher in all given attributes. © Emerald Group Publishing Limited.
Kant on Race and Barbarism: Towards a More Complex View on Racism and Anti-Colonialism in Kant

description: Whether Kant’s late legal theory and his theory of race are contradictory in their account of colonialism has been a much-debated question that is also of highest importance for the evaluation of the Enlightenment’s contribution to Europe’s colonial expansion and the dispossession and enslavement of native and black peoples. This article discusses the problem by introducing the discourse on barbarism. This neglected discourse is the original and traditional European colonial vocabulary and served the justification of colonialism from ancient Greece throughout the Renaissance to the eighteenth century. Kant’s explicit rejection of this discourse and its prejudices reveals his early critical stance toward colonial judgements of native peoples even before he developed his legal theory. This development of his critical position can be traced in his writings on race: although he makes racist statements in these texts, his theory of race is not meant to ground moral judgements on ‘races’ or a racial hierarchy but to defend the unity of mankind under the given empirical reality of colonial hierarchies.

description: Alluvial fans record climate-driven erosion and sediment-transport processes and allow reconstructing past environmental conditions. Here we investigate the sedimentation history of two alluvial fans located in formerly glaciated valleys of the Cordillera Oriental, Peru. 10Be exposure ages from the fan surfaces and radiocarbon ages from the fan interiors constrain the final stages of fan formation. The 10Be and 14C ages cluster mainly between 13.3–9.3 ka and 11,500–9700 cal yr BP, respectively. Our age data set indicates that—after deglaciation—large amounts of fan sediment were deposited until ∼10 ka, when sedimentation rates declined rather abruptly. This pattern is supported by 10Be erosion rates for the fan catchments, because under the assumption of constant erosion the time needed to erode the material stored in the fans significantly exceeds their age. Correlating our ages with regional climate records indicates that precipitation exerts the primary control on fan sedimentation. Two periods with elevated lake levels and increased precipitation between 18 and 14.5 ka and from 13 to 11.5 ka resulted in rapid deposition of large fan lobes. Subsequently, lower precipitation rates decreased erosion in the catchments and sediment delivery to the fans, which have remained largely inactive since ∼9.5 ka.

description: We provide sufficient conditions to factorise an equivariant spectral triple as a Kasparov product of unbounded classes constructed from the group action on the algebra and from the fixed point spectral triple. We show that if factorisation occurs, then the equivariant index of the spectral triple vanishes. Our results are for the action of compact abelian Lie groups, and we demonstrate them with examples from manifolds and θ-deformations. In particular, we show that equivariant Dirac-type spectral triples on the total space of a torus principal bundle always factorise. Combining this with our index result yields a special case of the Atiyah–Hirzebruch theorem. We also present an example that shows what goes wrong in the absence of our sufficient conditions (and how we get around it for this example).

description: The purpose of the article is analysis of factors of the diversity of opinions regarding marriage and parenthood in European countries as well as in Russia based on European Social Survey-2018. Dependent variables are opinions regarding the rights of homosexual people to live their own life, the rights of same-sex couples to adopt children, childlessness, cohabitation, fragile families, divorcing with children and regarding of mothers, who has a full-time job while she has children aged under 3 years old. It found that the problems of same-sex couples and conscious childlessness are the most topical among habitants of European countries. The main independent variables hypothetically influencing these opinions in European countries: behavior of inhabitants (measured by statistic indicators: total fertility rate, birthrate outside marriage, cohabitations and divorces) and legislation. Opinions and behaviors in most European countries correspond in relation to childlessness, cohabitation and outside marriage births. The links between legislation and opinions are ambiguous. These connections are established in relation to new social practices (same-sex unions, adoption of children by them), but not in relation to divorce, that is, the already established norm of behavior. Such variables of intra-Russian differences as gender, the presence of children, age group, education and religiosity were analyzed. It is shown that the most differentiating factor of opinions about marriage and parenthood in Russia is the generation. The opinions of Russians are more liberal in younger age groups and more conservative in older ones. As for cohabitation, in Russia the difference between age groups is greater than the difference between European countries.

The health care, prevention, and treatment of ethnic minorities have improved and improved significantly. However, access to preventive and curative medical services for ethnic minorities still has many issues that need to be addressed. The conduct of ethnic minority people in the prevention and treatment of diseases is still limited, such as self-treatment, spiritual healing, and local practices, lack of knowledge, and subjectivity when suffering from illness. From there, they will choose different types of health services. This reflects the awareness, practical ability, and the level of medical culture of the people. Therefore, raising awareness and change the perception of ethnic minorities in disease prevention and treatment are essential issues to improve access to health services in the mountainous areas today.

description: $^{75}$As and $^{45}$Sc NMR measurements unravel the electronic state for Fe-based superconductors with perovskite-type blocking layers Ca$_4$(Mg,Ti)$_3$Fe$_2$As$_2$O$_{8-y}$ ($T_c^{onset}=47$ K) and Ca$_5$(Sc,Ti)$_4$Fe$_2$As$_2$O$_{11-y}$ ($T_c^{onset}=41$ K). In Ca$_5$(Sc,Ti)$_4$Fe$_2$As$_2$O$_{11-y}$, the nuclear spin relaxation rate $1/T_1$ shows pseudogap behavior below $\sim80$ K, suggesting that the electronic state is similar to that of LaFeAs(O,F) system with moderate electron doping. The presence of the pseudogap behavior gives an interpretation that the hole-like band (so-called $γ$ pocket) is located just below the Fermi level from the analogy to LaFeAs(O,F) system and the disappearance of the $γ$ pocket yields the suppression of the low-energy spin fluctuations. On the other hand, in Ca$_4$(Mg,Ti)$_3$Fe$_2$As$_2$O$_{8-y}$ satisfying the structural optimal condition for higher $T_c$ among the perovskite systems, the extrinsic contribution, which presumably originates in the Ti moment, is observed in $1/T_1T$; however, the moderate temperature dependence of $1/T_1T$ appears by its suppression under high magnetic field. In both systems, the high $T_c$ of $\sim40$ K is realized in the absence of the strong development of the low-energy spin fluctuations. The present results reveal that the structural optimization does not induce the strong development of the low-energy spin fluctuations. If we consider that superconductivity is mediated by spin fluctuations, the structural optimization is conjectured to provide a benefit to the development of the high-energy spin fluctuations irrespective to the low-energy part.

description: The high quality spectra required for radial velocity planet searches are well-suited to providing abundances for a wide array of elements in large samples of stars. Abundance ratios of the most common elements relative to Fe are observed to vary by more than a factor of two in planet host candidates. This level of variation has a substantial impact on the evolution of the host star and the extent of its habitable zone. We present stellar models of 1 solar mass stars with custom compositions representing the full range of these non-solar abundance ratios. We find that the effects derived from variation over the observed range of [O/Fe] are particularly dramatic. Habitability lifetimes for some classes of orbits can vary by gigayears for the observed range in [O/Fe].

description: We develop a theoretical framework to investigate the interplay between quantum size effect (QSE) and strain effect on the stability of metal nanofilms. The QSE and strain effect are shown to be coupled through the concept of "quantum electronic stress. First-principles calculations reveal large quantum oscillations in the surface stress of metal nanofilms as a function of film thickness. This adds extrinsically additional strain-coupled quantum oscillations to surface energy of strained metal nanofilms. Our theory enables a quantitative estimation of the amount of strain in experimental samples, and suggests strain be an important factor contributing to the discrepancies between the existing theories and experiments.

description: Let W⊂GL(V) be a complex reflection group and A(W) the set of the mirrors of the complex reflections in W. It is known that the complement X(A(W)) of the reflection arrangement A(W) is a K(π,1) space. For Y an intersection of hyperplanes in A(W), let X(A(W)Y) be the complement in Y of the hyperplanes in A(W) not containing Y. We hope that X(A(W)Y) is always a K(π,1). We prove it in case of the monomial groups W=G(r,p,ℓ). Using known results, we then show that there remain only three irreducible complex reflection groups, leading to just eight such induced arrangements for which this K(π,1) property remains to be proved.

description: Using the quasi-classical formalism we provide the description of the temperature and field-direction dependence of the in-plane upper critical field in layered superconductors, taking into account the interlayer Josephson coupling and the paramagnetic spin splitting. We generalize the Lawrence-Doniach model for the case of high magnetic fields and show that the re-entrant superconductivity is naturally described by our formalism when neglecting the Pauli pair breaking effect. We demonstrate that in layered superconductors the in-plane anisotropy of the onset of superconductivity exhibits four different\ temperature regimes: from the Ginzburg-Landau type in the vicinity of the critical temperature $T_{c0}$ with anisotropies of coherence lengths, up to the FFLO type induced by the strong interference between the modulation vector and the orbital effect. Our results are in agreement with the experimental measurements of the field-angle dependence of the superconducting onset temperature of the organic compound (TMTSF)$_{2} $ClO$_{4}$.

description: We prove that a Kummer surface defined over a complete strictly Henselian discretely valued field K of residue characteristic different from 2 admits a strict Kulikov model after finite base change. The Kulikov models we construct will be schemes, so our results imply that the semistable reduction conjecture is true for Kummer surfaces in this setup, even in the category of schemes. Our construction of Kulikov models is closely related to an earlier construction of Künnemann, which produces semistable models of Abelian varieties. It is well known that the special fibre of a strict Kulikov model belongs to one of three types, and we shall prove that the type of the special fibre of a strict Kulikov model of a Kummer surface and the toric rank of a corresponding Abelian surface are determined by each other. We also study the relationship between this invariant and the Galois representation on the second ℓ-adic cohomology of the Kummer surface. Finally, we apply our results, together with earlier work of Halle–Nicaise, to give a proof of the monodromy conjecture for Kummer surfaces in equal characteristic zero.

description: We analyze the emergence of synchronization in a population of moving integrate-and-fire oscillators. Oscillators, while moving on a plane, interact with their nearest neighbor upon firing time. We discover a non-monotonic dependence of the synchronization time on the velocity of the agents. Moreover, we find that mechanisms that drive synchronization are different for different dynamical regimes. We report the extreme situation where an interplay between the time-scales involved in the dynamical processes completely inhibit the achievement of a coherent state. We also provide estimators for the transitions between the different regimes.

The no-core shell model with general radial bases

description: Calculations in the ab initio no-core shell model (NCSM) have conventionally been carried out using the harmonic-oscillator many-body basis. However, the rapid falloff (Gaussian asymptotics) of the oscillator functions at large radius makes them poorly suited for the description of the asymptotic properties of the nuclear wavefunction. We establish the foundations for carrying out no-core configuration interaction (NCCI) calculations using a basis built from general radial functions and discuss some of the considerations which enter into using such a basis. In particular, we consider the Coulomb-Sturmian basis, which provides a complete set of functions with a realistic (exponential) radial falloff.

description: Against the background of the emergence of macroeconomic imbalances within the European Monetary Union (EMU), we investigate in this paper the macroeconomic consequences of cross-border banking in monetary unions such as the Euro area. For this purpose, we incorporate a union-wide banking sector along the lines in an otherwise standard two-region monetary union DSGE model, accounting for borrowing constraints of entrepreneurs and impatient households and an internal constraint on the bank's leverage ratio. We illustrate in particular how rule-of-thumb lending standards based on the macroeconomic performance of the core region within the monetary union can translate into destabilizing spill-over effects into the other region, resulting in an overall higher macroeconomic volatility. Thereby, we demonstrate a channel through which the financial sector may have exacerbated the emergence of macroeconomic imbalances within the EMU. This effect may be mitigated by macroprudential policies, where especially policies that force the bank's lending standards to be less procyclical prove to be effective in stabilizing output in both regions of the monetary union.
Partial parameterization of orthogonal wavelet matrix filters

description: In this paper we propose a procedure which allows the construction of a large family of FIR d x d matrix wavelet filters by exploiting the one-to-one correspondence between QMF systems and orthogonal operators which commute with the shifts by two. A characterization of the class of filters of full rank type that can be obtained with such procedure is given. In particular, we restrict our attention to a special construction based on the representation of SO(2d) in terms of the elements of its Lie algebra. Explicit expressions for the filters in the case d = 2 are given, as a result of a local analysis of the parameterization obtained from perturbing the Haar system.

Test for changes in the modeled solvency capital requirement of an internal risk model

description: In the context of the Solvency II directive, the operation of an internal risk model is a possible way for risk assessment and for the determination of the solvency capital requirement of an insurance company in the European Union. A Monte Carlo procedure is customary to generate a model output. To be compliant with the directive, validation of the internal risk model is conducted on the basis of the model output. For this purpose, we suggest a new test for checking whether there is a significant change in the modeled solvency capital requirement. Asymptotic properties of the test statistic are investigated and a bootstrap approximation is justified. A simulation study investigates the performance of the test in the finite sample case and confirms the theoretical results. The internal risk model and the application of the test is illustrated in a simplified example. The method has more general usage for inference of a broad class of law-invariant and coherent risk measures on the basis of a paired sample.

description: Analyzing several developed and emerging international markets, I test the ability of global, regional, and local models to explain a large set of 134 cross-sectional anomalies. My main finding is that both global and regional factor models create substantially larger average absolute alphas than local factor models. Annual (absolute) anomaly portfolio alphas are on average 1.7 and 1.1 percentage points higher, respectively, with global and regional than with local factor models. Even for the most recent period, there is no evidence of a catch-up of global and regional factor models. There is substantial potential for international diversification of anomaly strategies.

description: We present the first blind interferometric detection and imaging of a millisecond radio transient with an observation of transient pulsar J0628+0909. We developed a special observing mode of the Karl G. Jansky Very Large Array (VLA) to produce correlated data products (i.e., visibilities and images) on a time scale of 10 ms. Correlated data effectively produce thousands of beams on the sky that can localize sources anywhere over a wide field of view. We used this new observing mode to find and image pulses from the rotating radio transient (RRAT) J0628+0909, improving its localization by two orders of magnitude. Since the location of the RRAT was only approximately known when first observed, we searched for transients using a wide-field detection algorithm based on the bispectrum, an interferometric closure quantity. Over 16 minutes of observing, this algorithm detected one transient offset roughly 1' from its nominal location; this allowed us to image the RRAT to localize it with an accuracy of 1.6". With a priori knowledge of the RRAT location, a traditional beamforming search of the same data found two, lower significance pulses. The refined RRAT position excludes all potential multiwavelength counterparts, limiting its optical luminosity to L_i'<1.1x10^31 erg/s and excluding its association with a young, luminous neutron star.
