description: A lot of studies are showing an increased tendency to use more than one
mode of administration to collect data for a particular analysis ([10];[1];[16];[9]).
Thus, understand if different data collection methods influence answers becomes
a concern. The problem of self selection into different interview modes demands
attention especially when the assignment to one or another collection method is
not randomly controlled and respondents might self select in one data collection
method over another. This paper shows an empirical case concerning the evalua-
tion of two different data collection method: the CAWI (Computer Assisted Web
Interview) method and the CATI (Computer Assisted Telephone Interview) method.
If self-selection exists both mode of data collection and characteristics of the re-
spondents influence answers. Hence, the mode effect may be confounded. In order
to estimate an unbiased mode effect, this paper proposes a data driven multivariate
approach to monitor self-selection that allows to disentangle interview’s modes ef-
fects on answers from the effect of self-selection. We will work through the use of
the monitoring system with an empirical case. In particular, we will use AlmaLaurea
data and compare results of our approach to PS adjustment method that AlmaLaurea
usually applies to control data quality as documented in various reports and analysis
conducted by the AlmaLaurea Consortium .

description: A C*-algebra is n-homogeneous (where n is finite) if every its nonzero irreducible representation acts on an n-dimensional Hilbert space. An elementary proof of Fell's characterization of n-homogeneous C*-algebras (by means of their spectra) is presented. A spectral theorem and a functional calculus for finite systems of elements which generate n-homogeneous C*-algebras are proposed.

description: In den vergangenen Jahren wurde die Akquise privater Spenden in Deutschland immer mehr zu einem Pfeiler der Finanzierung der Arbeit vieler Non-Profit-Organisationen. Die Interessen der Spender als „Stakeholder“ einer Organisation rückten dabei in den Vordergrund. Auch auf der wissenschaftlichen Ebene wurden Spender stärker zu einem Untersuchungsfeld und ihre Einstellungen zu einem Indikator der relevanten Wandlungsprozesse im „Dritten Sektor“. Dem gegenüber sind die Spendenmotive für den deutschen Raum nur sehr marginal erforscht, so dass kaum Hypothesen zu den Spendenmotiven und –motivstrukturen möglich sind. Diese Arbeit möchte zur Schließung dieser Lücke durch eine explorative, qualitative Studie beitragen. Hierfür wurden 30 Spender mittels teilnarrativer, biographischer Interviews befragt und eine Spendertypologie entwickelt. Darüber hinaus wurden fallübergreifende Aspekte wie Spenden in der Herkunftsfamilie oder die Herstellung von Betroffenheit anhand der Daten weitergehend beleuchtet.

description: Additional file 2 Adjusted linear mixed model for the Substance Use Severity Index (SUSI) for patients with two or more SUSI measurements (N = 170). CI: Confidence Interval; OAT: Opioid Agonist Therapy; cSUSI: Mean Change in Substance Use Severity Index; SUD: Substance Use Disorder. 1) The SUSI is a continuous variable ranging from 0 to 1, where 0 indicates no substance use and 1 indicates daily substance use for all substances (cannabis, amphetamines, cocaine, opioids, benzodiazepines, and alcohol). 2) The value shows the difference in adjusted SUSI between “going to inpatient detoxification” and “not going to inpatient detoxification” at baseline (before detoxification). 3) Interpretation: the cSUSI per year from baseline of a constant predictor and its comparator (e.g., the cSUSI of “ongoing injecting substance use” (constant predictor) and “no ongoing inject substance use” (constant comparator) per year from baseline). 4) Interpretation: the cSUSI of a time-varying predictor and its time-varying comparator per year from baseline (e.g., the cSUSI per year of “going to inpatient detoxification” and “not going to inpatient detoxification” from baseline). The table displays a linear mixed model analysis (Restricted Maximum Likelihood regression) evaluating the impact of inpatient intoxication, injecting substance use, age, and gender on the SUSI at baseline and from baseline (over time) among patients undergoing outpatient SUD treatment with two or more substance use measurements.
Cardiovascular risk and disease among people with mental health disorders in Canada
Creators: name: Goldie, Catherine Lindsay
Publisher: name: University of British Columbia
Year: 2014

description: Although research has revealed that there is excess cardiovascular morbidity among persons with mental health disorders (MHD), there is limited evidence specific to the Canadian context. It is also unclear if elevated rates of cardiovascular disease (CVD) can be attributed to MHDs themselves or to exposure to psychoactive medications. Moreover, few researchers have extended their investigations to account for psychiatric comorbidity or have applied cardiovascular risk prediction algorithms to conduct comprehensive assessments of this population’s heart health. Three studies were undertaken utilizing cross-sectional data obtained via the Canadian Community Health Survey Cycle 1.2. MHDs were assessed using the World Mental Health Composite International Diagnostic Interview. Frequency of psychoactive medication use, the presence of heart disease, and stroke and cardiovascular risk factors were also assessed. Framingham risk prediction algorithms were used to calculate cardiovascular risk. Descriptive statistics were employed to estimate the prevalence of CVD in people with a range of MHDs and psychoactive medication use. Associations between MHDs, psychoactive medication use, and cardiovascular risk and CVD were analyzed with logistic regression. Confidence intervals for the proportions and odds ratios were calculated using weighted bootstrapped estimates to take into account the complex survey design and nonresponse. Our examination of psychiatric comorbidity revealed that a small proportion of Canadians suffer from a heavy burden of MHDs and that disorders often co-occur. Respondents with any lifetime MHD were twice as likely to have a history of heart disease or stroke, and those without heart disease or stroke were more likely to be at high risk of developing CVD within 30-years compared to people without a diagnosis of a MHD. Similarly, people reporting psychoactive medication use were twice as likely to have heart disease, three times as likely to report having had a stroke, and more likely to be in the highest 30-year risk category for CVD compared to people not reporting psychoactive medication use. Negligible confounding was found between the effects of psychoactive medication use and having a MHD on heart health. These findings underscore the need for continued monitoring of CVD among Canadians with MHDs and development of effective preventative strategies.
A New Strategy for Reducing Selection Bias in Non-Experimental Evaluations, and the Case of How Public Assistance Receipts Affects Charitable Giving.

description: Prior work has analyzed the extent to which welfare recipients engage in giving money and time to charitable causes (Brooks, 2002, 2004; Author4 & Author1, 2009; Author1 & Author4, 2011), finding that public assistance is negatively associated with donating money with the relationship to volunteering being unclear. Nevertheless, sticky issues of selection bias compel more deliberate thinking about the strength of assertions about cause and effect. In response, we now conduct a multivariate cluster-based subgroup analysis approach to more confidently infer causality about the ways in which welfare receipt affects charitable activity. This approach to dealing with the problem of selection bias capitalizes on the known treatment-associated variance in the X matrix, transforming data to estimate unbiased treatment effects. We contribute to both the substantive and methodological literatures with this work.

description: We live in a computerized and networked society where many of our actions leave a digital trace and affect other people's actions. This has lead to the emergence of a new data-driven research field: mathematical methods of computer science, statistical physics and sociometry provide insights on a wide range of disciplines ranging from social science to human mobility. A recent important discovery is that query volumes (i.e., the number of requests submitted by users to search engines on the www) can be used to track and, in some cases, to anticipate the dynamics of social phenomena. Successful exemples include unemployment levels, car and home sales, and epidemics spreading. Few recent works applied this approach to stock prices and market sentiment. However, it remains unclear if trends in financial markets can be anticipated by the collective wisdom of on-line users on the web. Here we show that trading volumes of stocks traded in NASDAQ-100 are correlated with the volumes of queries related to the same stocks. In particular, query volumes anticipate in many cases peaks of trading by one day or more. Our analysis is carried out on a unique dataset of queries, submitted to an important web search engine, which enable us to investigate also the user behavior. We show that the query volume dynamics emerges from the collective but seemingly uncoordinated activity of many users. These findings contribute to the debate on the identification of early warnings of financial systemic risk, based on the activity of users of the www.

Examination of test equivalence between French and English language versions of Progress in International Reading Literacy Study 2011
Creators: name: Goodrich, Shawna
Publisher: name: University of British Columbia
Year: 2014

description: In Canada, international large-scale assessments (LSAs), such as the Progress in International Reading Literacy Study (PIRLS), are administered in the two official languages, French and English. The validity of decisions made from these assessments depends on the equivalence of different language versions and the comparability of scores across language groups. Previous research examining French and English language versions of large-scale assessments administered in Canada indicates that equivalence cannot be assumed when tests are adapted (Ercikan, Gierl, McCreith, Puhan & Koh, 2004; Ercikan & McCreith, 2002; Gierl, 2000; Oliveri & Ercikan, 2011). Research has shown that the quality of test adaptation is particularly important to ensure comparability, interpretability and consequential equity across language groups. The purpose of this study is to examine test equivalence and score comparability at the item and test level between French and English language groups administered PIRLS 2011. Confirmatory factor analysis and two methods of differential item functioning were conducted to examine score comparability. Four bilingual expert reviewers with expertise in reading literacy conducted independent blind linguistic and cultural reviews to identify the degree of test equivalence and potential sources of differences between the French and English language versions of released items from PIRLS 2011. As a whole, evidence from this study indicates there are important scale level differences between the French and English language versions of PIRLS 2011 that call for further investigation and on average 25% of items across thirteen booklets function differently at the item level. Reviews by experts of released items indicate that there are many differences between the two language versions for both statistically identified DIF items and non-statistically identified items. Reviewers concluded that inappropriate translation produced unintended differences in content and difficulty levels between the two language versions.

description: Quantum discord, a measure of quantum correlation beyond entanglement, is initially defined as the discord between two classically equivalent while quantum discordant definitions of mutual information. In this paper, we report some new interpretations of discord which rely on the differences between measurement induced effects on the local measured system and the whole system. Specifically, with proper quantitative definitions introduced in [Buscemi, Hayashi and Horodecki, Phys. Rev. Lett. 100, 2210504 (2008)], we find that quantum discord can be interpreted as the differences of measurement induced disturbance or information gain on the local measured system and on the whole system. Combined with previous similar results based on measurement induced entanglement and decoherence, our results provide a unified view on quantum discord.

description: The scope of the Deliverable 6.1 is to introduce the causal qualitative model developed in the context
of the PERCEIVE project, as a part of the Working Package 6. The report begins with a short introduction
that highlights the necessity of developing a model for simulating: (i) the manner in which the European
Cohesion Policy funds are distributed among the regions under study and the factors that affect the related
absorption, along with the (ii) the diverse streams of communication of the European Cohesion Policy
projects and outcomes that influence the citizens awareness. The analysis of the system is focused on the
EU structural funds, namely the European Regional Development Fund (ERDF) and the European Social
Fund (ESF) during the two previous programming periods (i.e. 2000-2006, 2007-2013). In fact, the multilevel
nature of the system (i.e. EU, regions, beneficiaries), the dynamic behaviour over the programming
periods, as well as the complexity reflected through the multiple intertwined feedback loops render the
System Dynamics methodology as the appropriate approach to map and model the system under study.
Thus, we briefly present the basic elements and procedures of System Dynamics technique.

description: In this paper, we use subword complexes to provide a uniform approach to finite type cluster complexes and multi-associahedra. We introduce, for any finite Coxeter group and any nonnegative integer k, a spherical subword complex called multi-cluster complex. For k=1, we show that this subword complex is isomorphic to the cluster complex of the given type. We show that multi-cluster complexes of types A and B coincide with known simplicial complexes, namely with the simplicial complexes of multi-triangulations and centrally symmetric multi-triangulations respectively. Furthermore, we show that the multi-cluster complex is universal in the sense that every spherical subword complex can be realized as a link of a face of the multi-cluster complex.

intensity of the policy in the region and with the effectiveness in which the funds
allocated are finally spent? Is there a relationship between the deviation in funds’
allocations and actual expenditures, and the socio-economic characteristics of the
region? Finally, are citizens in growing and, particularly, converging regions more
prone to support the European project and have positive attitudes towards the
EU?

description: Der Übergang von der Trächtigkeit zur Frühlaktation (Transitzeit) stellt aufgrund einer sprunghaften Steigerung des Energiebedarfs eine hohe metabolische Belastung für die Milchkuh dar, wodurch inflammatorische Prozesse im tierischen Stoffwechsel aktiviert werden. Dies ist verbunden mit einer Induktion von Stress im endoplasmatischen Retikulum (ER) in der Leber von hochleistenden Milchkühen, welcher zur Entwicklung des Fettlebersyndroms und zur Ketose führen kann. Durch Hinzugabe eines polyphenolreichen Pflanzenextrakts (Traubentrester, Pflanzenprodukt aus Grüntee und Curcuma) kann sowohl die Inflammation, als auch der ER Stress in der Leber von Hochleistungskühen in der Frühlaktation verringert werden, was zur Verbesserung der Tiergesundheit und somit zu einer verbesserten Milchleistung führt.
description: The transition period, spanning the period of 3 weeks pre-partum to 3 weeks post-partum, is widely recognised as the most metabolically challenging time in the production cycle of high-yielding dairy cows due to metabolic and inflammatory stimuli, which are associated with the development of stress of the endoplasmic reticulum (ER) in the liver, which contributes to the development of liver-associated diseases. Supplementing a plant extract rich in flavonoids (grape seed and grape marc meal extract (GSGME), plant product consisting of green tea and curcuma extract) attenuates inflammation and ER stress in the liver of dairy cows in early lactation which leads to an enhancement of animal health associated with a significantly improved milk yield.

description: The primordial inflation dilutes all matter except the quantum fluctuations which we see in the cosmic microwave background (CMB) radiation. Therefore the last phases of inflation must be embedded within a beyond the Standard Model (SM) sector where the inflaton can directly excite the SM quarks and leptons. In this paper we consider two inflaton candidates LLe and udd whose decay can naturally excite all the relevant degrees of freedom besides thermalizing the lightest supersymmetric particle (LSP) during and after reheating. In particular, we present the regions of the parameter space which can yield successful inflation with the right temperature anisotropy in the CMB, the observed relic density for the neutralino LSP, and the recent Higgs mass constraints from LHC within the MSSM with non-universal Higgs masses -- referred to as the NUHM2 model. We found that in most scenarios, the LSP seems strongly mass degenerated with the next to lightest LSP (NLSP) and the branching ratio B_s -> mu^+ mu^- very close to the present bound, thus leading to falsifiable predictions. Also the dark matter interactions with XENON nuclei would fall within the projected range for the XENON1T experiment. In the case of a positive signal of low scale supersymmetry at the LHC, one would be able to potentially pin down the inflaton mass by using the associated values for the mass of the stau, the stop and the neutralino.

Corresponding probability distributions and their cumulants are derived analytically. We show that the conservation of baryon number results in a substantial decrease of higher order cumulants. Based on our studies, we propose an observable that is insensitive to the modifications due to baryon number conservation.

description: Projective measurements of a single two-level quantum mechanical system (a qubit) evolving under a time-independent Hamiltonian produce a probability distribution that is periodic in the evolution time. The period of this distribution is an important parameter in the Hamiltonian. Here, we explore how to design experiments so as to minimize error in the estimation of this parameter. While it has been shown that useful results may be obtained by minimizing the risk incurred by each experiment, such an approach is computationally intractable in general. Here, we motivate and derive heuristic strategies for experiment design that enjoy the same exponential scaling as fully optimized strategies. We then discuss generalizations to the case of finite relaxation times, T_2 < \infty.

description: A short review of Algebraic Geometry tools for the decomposition of tensors and polynomials is given from the point of view of applications to quantum and atomic physics.
Examples of application to assemblies of indistinguishable two-level bosonic atoms are discussed using modern formulations of the classical Sylvester's algorithm for the decomposition of homogeneous polynomials in two variables. In particular, the symmetric rank and symmetric border rank of spin squeezed states is calculated as well as their Schr\"odinger-cat-like decomposition as the sum of macroscopically different coherent spin states; Fock states provide an example of states for which the symmetric rank and the symmetric border rank are different.

description: A report on the spectroscopic and multi-color photometric observations of high galactic latitude classical nova KT Eridani (Nova Eridani 2009) is presented. After 12.2 days from maximum light, broad and prominent emission lines of Balmer series, He I, He II, N II, N III and O I can be seen on the spectra. The FWHM of H$α$ line yields an expansion velocity of approximately 3400 km s$^{-1}$. After 279.4 days from maximum light, we can see prominent emission lines of He II and [O III] on the spectrum. Among them, [O III] (4959, 5007) lines show multiple peaks. From the obtained light curve, KT Eri is classified to be a very fast nova, with a decline rate by two magnitude of $6.2 \pm 0.3$ days and three of $14.3 \pm 0.7$ days. We tried to estimate the absolute magnitude ($M_V$) using the Maximum Magnitude versus Rate of Decline relationship and distance of KT Eri. The calculated $M_V$ is approximately -9. Accordingly, the distance and galactic height are approximately 7 kpc and 4 kpc, respectively. Hence, KT Eri is concluded to be located outside of the galactic disk.

description: In this paper, we present a novel single-ended
active integrated bandpass filter employing recursive
principles. This circuit is based upon an original method to
combine input and delayed feedback signals of a first-order
recursive structure thanks to a differential pair
combination. The chip surface is 1.12 mm². The filter
performs a simulated gain close to 10 dB with a 160 MHz
bandwidth. Power consumption is about 32 mW. Noise
figure is 4.6 dB at the center frequency. Philips QUBIC4 Si
BiCMOS technology is used [1].

description: In this paper a novel low-cost SMD package
for high-power MMICs is presented. Due to the special
design this package has a very low thermal resistance and
low parasitic ground inductance. 3D EM simulations of a
packaged through-line correspond well with measurements.
Measurement results of a 1 Watt 40 GHz HPA before and
after packaging are presented. The gain reduction at
40 GHz caused by the package is only 1 dB. Experimental
results are given for different package options: with or
without compensation circuit on the package and with or
without bondwire compensation on the MMIC.

description: A central quantity in mean-field magnetohydrodynamics is the mean electromotive force EMF, which in general depends on the mean magnetic field. It may however have a part independent of the mean magnetic field. Here we study an example of a rotating conducting body of turbulent fluid with non-zero cross-helicity, in which a contribution to the EMF proportional to the angular velocity occurs (Yoshizawa 1990). If the forcing is helical, it also leads to an alpha effect, and large-scale magnetic fields can be generated. For not too rapid rotation, the field configuration is such that Yoshizawa's contribution to the EMF is considerably reduced compared to the case without alpha effect. In that case, large-scale flows are also found to be generated.

description: Four low noise amplifiers for 94 GHz cloud radar are presented. One LNA is designed using coplanar
waveguides and the others use microstrip lines. 
The designed amplifiers were manufactured with a metamorphic high electron mobility transistor (MHEMT) technology and the chip size is 2.1 mm x 1.1 mm. 
The four stage LNAs have either 2x25 µm or 4x25 µm size MHEMTs. The scattering parameters and the noise figures of the amplifiers were measured at W-band and the results are presented. The best measured gain at 94 GHz was 16 dB and the noise figure 5.7 dB using a 2.5 V supply voltage and a drain current of 15 mA per stage. Furthermore, one of the amplifiers was assembled in a package that has WR-10 waveguide interfaces. The packaged chip exhibited 10.8 dB of gain and the noise figure was 8 dB at 94 GHz.

description: Trotz des Potentials von Bioenergie, Treibhausgasemissionen zu senken oder die energetische Versorgungssicherheit zu erhöhen, können regionale soziale und ökologische Effekte auftreten. Diese werden in bisherigen Bewertungen kaum berücksichtigt. Dieses Projekt hat die Ziele, für Biomasseproduktion zu testen, (i) ob Zertifizierungssysteme als dominierendes Governanceinstrument für regionale Umweltfolgen eine verlässliche Umweltbewertung zulassen, (ii) ob Faktoren auf Landschaftsebene die Bereitstellung von Ökosystemdienstleistungen (ÖSD) beeinflussen und (iii) wie Umweltfolgentrotz naturräumlicher Heterogenität zwischen verschiedenen Regionen verglichen werden können (Südosten der USA, Tansania undMitteldeutschland). Die Ergebnisse zeigen, dass Zertifizierungssysteme kaum regionale Treiber und Umweltfolgen der Biomasseproduktion berücksichtigen. Für Fallstudien im Südosten der USA wurden mehr als 30 % der Varianz in der Bereitstellung von ÖSD durch die Struktur und Natürlichkeit der Landschaft erklärt.Wirtschaftswald (Mitteldeutschland) hat die höchsten positiven Umweltfolgen.Es wurden drei Ansätze entwickelt, um Umweltfolgen trotz naturräumlicher Heterogenität weltweit vergleichbar zu machen.
description: Despite the potential of bioenergy to reduce greenhouse gas emissions or to guarantee energy supply, several regional social and environmental impacts could occur. These impacts are hardly considered in existing assessments. This project aims to test for biomass production for bioenergy (i) whether certification schemes as major governance mechanism allow a reliable environmental assessment, (ii) whether regional-scale factors drive the supply of multiple ecosystem services (ESS), and (iii) how environmental impacts could be compared despite environmental heterogeneity between different world regions (Southeastern US, Tanzania, and Central Germany). The results showed that certification schemes missed to assess regional-scale drivers and impacts of biomass production on the environment. For case studies in the Southeastern US, more than 30 % of the variance in ESS supply depended on regional factors, landscape structure and naturalness. Managed forests in Central Germany had the most positive environmental impact values. Three approaches have been developed to make environmental impacts worldwide comparable despite environmental heterogeneity.

description: To improve sensitivity of optical receivers, a
special integration concept is chosen that includes a pinphotodiode, high-electron mobility transistors (HEMT) and
heterostructure bipolar transistors (HBT) on a single
substrate. This work focuses on the optimization of the
amplifier design to achieve lowest input noise currents of a
transimpedance amplifier, and thus highest receiver
sensitivity. The respective advantages of the components
used are investigated with respect to the noise behaviour.
Different circuits have been simulated and an amplifier
design is presented that best fits the requirements for high
optical sensitivity.

description: We consider time reversal transformations to obtain twofold orthogonal splittings of any tensor on a Lorentzian space of arbitrary dimension n. Applied to the Weyl tensor of a spacetime, this leads to a definition of its electric and magnetic parts relative to an observer (i.e., a unit timelike vector field u), in any n. We study the cases where one of these parts vanishes in particular, i.e., purely electric (PE) or magnetic (PM) spacetimes. We generalize several results from four to higher dimensions and discuss new features of higher dimensions. We prove that the only permitted Weyl types are G, I_i and D, and discuss the possible relation of u with the WANDs; we provide invariant conditions that characterize PE/PM spacetimes, such as Bel-Debever criteria, or constraints on scalar invariants, and connect the PE/PM parts to the kinematic quantities of u; we present conditions under which direct product spacetimes (and certain warps) are PE/PM, which enables us to construct explicit examples. In particular, it is also shown that all static spacetimes are necessarily PE, while stationary spacetimes (e.g., spinning black holes) are in general neither PE nor PM. Ample classes of PE spacetimes exist, but PM solutions are elusive, and we prove that PM Einstein spacetimes of type D do not exist, for any n. Finally, we derive corresponding results for the electric/magnetic parts of the Riemann tensor. This also leads to first examples of PM spacetimes in higher dimensions. We also note in passing that PE/PM Weyl tensors provide examples of minimal tensors, and we make the connection hereof with the recently proved alignment theorem. This in turn sheds new light on classification of the Weyl tensors based on null alignment, providing a further invariant characterization that distinguishes the types G/I/D from the types II/III/N.
