description: Children who have developmental disorders that involve memorial deficits and impairments in social interaction and communication, such as Autism Spectrum Disorders (ASD), can present challenges to professionals seeking their testimony when they are victims or witnesses of a crime. Most forensic interviews involve long delays after an event, underscoring the importance of conducting experimental studies which consider the effect of delay on children’s memory. In this research, fifty-nine children (age 6-15 years) with ASD (N=27) and without disabilities (N=32) were questioned about their participation in a set of activities after a two-week delay and again after a two-month delay, using the Revised National Institute of Child Health and Human Development (NICHD) Investigative Interview Protocol. A detailed coding scheme was designed to code and analyse the interviewers’ utterances and the children’s responses in 118 interviews. Transcripts were coded for completeness (with respect to the gist of the event), amount of narrative details, and accuracy. Results indicated that autistic children did not differ from typically developing (TD) peers on any dimensions of memory after both delays. Specifically, both groups of children provided equivalently complete accounts on both occasions. However, children in both groups provided significantly fewer narrative details about the event in the second interview, and the accuracy rates were lower. Recall prompts elicited more detailed and more accurate responses from children in both groups than recognition prompts. Although autistic children recalled fewer correct narrative details than TD peers when questioned using open-ended recall prompts, they were as accurate as TD peers in response to recognition prompts. The informativeness and accuracy of children's reports remained unchanged over time. Finally, social support was beneficial when children were interviewed for the first time but not after a longer delay. The findings indicate that autistic children can provide meaningful and reliable testimony about an event they personally experienced, but several aspects of their memory reports deteriorate over time.

inheritance taxation

description: In a recent representative survey, German citizens are asked whether or not inherited wealth beyond a certain amount should be taxed. Almost 60 percent stated that it should not be taxed. We use this survey to identify the factors that drive this fundamental opposition against the taxation of inherited wealth. We find monetary self-interest and redistributive preferences to drive citizens’ attitude in this matter. We account for other intra-familial transfers, in particular long-term care. Being at the heart of intra-familial exchange relations, women are more likely to oppose wealth transfer taxation than men are. Citizens’ attitude towards inheritance taxation does not depend on their personal experience in giving long-term care. Expecting the typical German family to reward intra-familial caregiving through a higher inheritance reduces the opposition against the taxation of inherited wealth.

data ownership

description: The discussion about appropriate legal rules for the digital economy has raised the question of the ownership of non-personal data, e.g. in the context of value networks of firms, smart manufacturing and connected cars. The article analyzes from an economic perspective whether there is a need for a new exclusive IPR on data. It is shown that there are no convincing economic arguments for the in-troduction of such a new IPR, especially due to the lack of an incentive problem for the production and analysis of data. On the contrary, a new IPR on data might lead to considerable problems and dangers for competition and innovation, especially for the digital economy, which depends on the access to a broad variety of data. Therefore problems of access to data might be a much more im-portant policy issue than exclusive property rights on data.

description: We study the properties of strange quark stars by employing a 3-flavor Nambu-Jona-Lasinio model with both scalar-isovector and vector-isovector interactions. Using the constraint on the vector-isoscalar interaction strength obtained from the elliptic flow splitting between particles and their antiparticles in relativistic heavy-ion collisions, we investigate the dependence of the properties of strange quark stars on the vector-isovector and the scalar-isovector interactions, and compare the results with the state-of-art astrophysical constraints on the compact star radius and mass as well as its tidal deformability from the GW170817 event. Results from our study reinforce the prospect of using both heavy-ion collisions and astrophysical observations to provide constraints on the isovector coupling strength in quark matter and thus the quark matter equation of state as well as the QCD phase structure at finite isospin chemical potentials.

description: We derive general bounds on the Type-III Seesaw parameters from a global fit to flavor and electroweak precision data. We explore and compare three Type-III Seesaw realizations: a general scenario, where an arbitrary number of heavy triplets is integrated out without any further assumption, and the more constrained cases in which only 3 or 2 (minimal scenario) additional heavy states are included. The latter assumption implies rather non-trivial correlations in the Yukawa flavor structure of the model so as to reproduce the neutrino masses and mixings as measured in neutrino oscillations experiments and thus qualitative differences can be found with the more general scenario. In particular, we find that, while the bounds on most elements of the dimension 6 operator coefficients are of order $10^{-4}$ for the general and 3-triplet cases, the 2-triplet scenario is more strongly constrained with bounds between $10^{-5}$ and $10^{-7}$ for the different flavours. We also discuss how these correlations affect the present CMS constraints on the Type-III Seesaw in the minimal 2-triplet scenario.

description: Understanding the role of climatic and ecological factors in limiting species to their distributions is becoming ever more important in a world where anthropogenic activities are increasingly threatening species persistence. Species with restricted distributions are often poorly known even though they may be most vulnerable to extinction. We investigated the influences of climate and ecology on the distribution of five understudied, endemic, rupicolous reptiles from the Soutpansberg Mountains in South Africa. Using Maxent, we developed ecological niche models that were used to provide baseline insights into the factors delimiting these species distributions. Results indicated that most species were limited by climatic factors, with the average temperature of the coolest quarter having the most influence on the majority of the species, where they were limited to areas with cooler temperatures. This suggests that they may be negatively affected by climate change in the future. Distribution maps revealed that there were no strong interspecific interactions influencing the distributions between the species investigated and identified potential new localities for two species. There was high endemic richness located in the western Soutpansberg and this is likely to have been driven by past climatic and erosion events. Overall this study highlighted that performing environmental niche models on understudied species can provide essential, baseline information on which to drive future research.

description: How does one lead a life of law, love and freedom? This inquiry has very deep roots in the Judeo-Christian tradition. Indeed, the divergent answers to this inquiry mark the transition from Judeo to Christian. This dissertation returns to those roots to trace the routes that these ideas have taken as they move from the sacred to the secular. The argument of this dissertation is threefold. First, it argues that the concepts of law, love and freedom are each internally polarized. Each concept contains, within itself, conflicting values. Paul’s equivocation in his letters is a striking manifestation of this internal polarization. Second, it argues that, while values are many, my life is one. Hence, one needs to combine the plurality of values within a singular life. Values find their coherence within a form of life. There are, at least, two ways of leading a life of law, love and freedom: monastic versus antinomian. Third, it argues that the Reformation transformed these religious ideals into political ideologies. The monastic ideal is politically manifested as constitutionalism, and the antinomian ideal is politically manifested as anarchism. There are, at least, two ways of creating a polity of law, love and freedom: constitutional versus anarchic. To mount the threefold argument, the dissertation deploys a whole range of disciplinary tools. The dissertation draws on analytic jurisprudence in its analysis of law; ethics and aesthetics in its analysis of love; political philosophy in its analysis of freedom; biblical scholarship in its interpretation of Paul; the history of ideas in its study of the formation and transformation of these ideas; and moral philosophy in concluding how one could lead a life of law, love and freedom.
The Phenomenon of Quiet Quitting: A Scoping Review

subject: Human resources management

description: The discourse of quiet quitting has recently emerged and become increasingly popular in social and public media. The phenomenon refers to situations in which employees do not want to undertake extra work responsibilities and only fulfil essential work requirements to maintain their employment. Academic interest in quiet quitting behaviour has also precipitated a significant increase in the number of publications over the last 2 years. This exploratory study investigated extant literature to discover the meaning, trends, motivations, consequences and theories associated with quiet quitting. To build research knowledge, a scoping review was conducted to examine the emergence of quiet quitting in the nascent academic literature. Twenty-five published academic articles were included in the analysis. The findings indicate that while quiet quitting appears to share similarities with many other established workplace phenomena, they are not the same. Quiet quitting has distinct underlying notions that should not be confused with other workplace phenomena. Toxic workplace cultures, inadequate remuneration, and decreased employee well-being all contributed to individuals’ engagement with quiet quitting behaviour. While quiet quitting challenges organisational productivity and innovation capabilities, it also provides opportunities for employees to regain their work-life balance and for organisations to reflect on their current managerial practices. The findings also show that social exchange theory, psychological contract theory, and equity theory are the most common analytical frameworks used to explain quiet quitting. The present research contributes several theoretical and practical insights that illuminate the understanding of this new phenomenon in contemporary workplaces.
Semiclassical Theory of the Magnonic Isospin in Antiferromagnets

Publisher: name: Carnegie Mellon University
Year: 2019
Subjects: subject: 20399 Classical Physics not elsewhere classified

description: In this dissertation, we introduce the concept of magnonic isospin, an internal degree of freedom for antiferromagnetic spin waves which carries spin but acts as a charge in reacting to the emergent electromagnetic fields of the underlying ground state. The isospin vector parameterizes the degenerate subspace of the two antiferromagnetic spin wave modes in the unperturbed Heisenberg model. To derive the dynamics of this isospin vector, we extend the nonabelian wavepacket theory by accounting for the unusual properties of the pseudo-Hermitian Hamiltonian generating the spin wave dynamics. Using the emergent
Schrödinger equation governing the isospin, we make several predictions about possible magnonic devices utilizing this new, nonabelian degree of freedom.

description: This paper presents an evaluation of several approaches of plants species distribution modeling based on spatial, environmental and co-occurrences data using machine learning methods. In particular, we re-evaluate the environmental convolutional neural network model that obtained the best performance of the GeoLifeCLEF 2018 challenge but on a revised dataset that fixes some of the issues of the previous one. We also go deeper in the analysis of co-occurrences information by evaluating a new model that jointly takes environmental variables and co-occurrences as inputs of an end-to-end network. Results show that the environmental models are the best performing methods and that there is a significant amount of complementary information between co-occurrences and environment. Indeed, the model learned on both inputs allows a significant performance gain compared to the environmental model alone.

description: Remittance inflows from overseas workers are an important source of for-
eign funding for developing and emerging economies. The literature is in-
conclusive about the cyclical nature of remittance inflows. To the extent remittances are procyclical they pose a challenge to monetary policy: a tightening of policy will be less effective if at the same time remittances increase strongly. The same is true for a policy easing under exceptionally weak remittance inflows. This paper estimates a series of nonlinear (smooth-transition) local projections to study the effectiveness of monetary policy under different remittance inflows regimes. The model is able to provide state-dependent
impulse response functions. We show that for Kenya, Mexico, Colombia and
the Philippines monetary policy indeed has a smaller domestic effect under
strong inflows of remittances. These results have important implications for
the design of inflation targeting in developing countries.

description: The timing properties of the millisecond pulsar PSR J1939+2134 -- very high rotation frequency, very low time derivative of rotation frequency, no timing glitches and relatively low timing noise -- are responsible for its exceptional timing stability over decades. It has been timed by various groups since its discovery, at diverse radio frequencies, using different hardware and analysis methods. Most of this timing data is now available in the public domain in two segments, which have not been combined so far. This work analyzes the combined data by deriving uniform methods of data selection, derivation of Dispersion Measure (DM), accounting for correlation due to "red" noise, etc. The timing noise of this pulsar is very close to a sinusoid, with a period of approximately $31$ years. The main results of this work are (1) The clock of PSR J1939+2134 is stable at the level of almost one part in $10^{15}$ over about $31$ years, (2) the power law index of the spectrum of electron density fluctuations in the direction of PSR J1939+2134 is $3.86 \pm 0.04$, (3) a Moon sized planetary companion, in an orbit of semi major axis about $11$ astronomical units and eccentricity $\approx 0.2$, can explain the timing noise of PSR J1939+2134, (4) Precession under electromagnetic torque with very small values of oblateness and wobble angle can also be the explanation, but with reduced confidence, and (5) there is excess timing noise of about $8$ $μ$s amplitude during the epochs of steepest DM gradient, of unknown cause.
Combinatorial DNA barcoding for security applications

Subjects: Uncategorized

description: Forensic tagging has been widely used in recent years – from the use in large companies or institutions, to preventing large scale cable theft to private home owners who want to protect their property. Such tagging can be done by applying a solution containing a unique DNA code to devices, doors or valuable objects. Another method for forensic tagging is a spraying device which also deploys a unique code onto intruders. This code can then be decoded and used to create a link between criminal and the house/institution where the device was deployed or the solution applied to property. The market for such forensic applications within the UK is largely dominated by SmartWater® and SelectaDNA®. However, both companies base their decoding method on the time-consuming and expensive technique of sequencing. In collaboration with the security company Spyral®, we have developed a combinatorial system which exploits the advantages of Real-Time PCR (qPCR). Synthetic oligonucleotide constructs were designed, consisting of primer pair amplification sites and a target site, the latter to which a fluorescent probe can bind. The original approach for the target site detection involved HyBeacons® which are already extensively used in forensic science. After encountering many difficulties using these probes, the experimental approach was changed and TaqMan® probes were used which are already well-established for qPCR experiments. Having established a stable detection system using TaqMan®, it was shown that, despite limitations, mixtures containing several oligonucleotides could be decoded. The final series of experiments showed a positive outcome for deployment and subsequent recovery of the oligonucleotides.

description: Vertical stacking of atomically thin layered materials opens new possibilities for the fabrication of heterostructures with favorable optoelectronic properties. The combination of graphene, hexagonal boron nitride and semiconducting transition metal dichalcogenides allows fabrication of electroluminescence (EL) devices, compatible with a wide range of substrates. Here, we demonstrate a full integration of an electroluminescent van der Waals heterostructure in a monolithic optical microcavity made of two high reflectivity dielectric distributed Bragg reflectors (DBRs). Owing to the presence of graphene and hexagonal boron nitride protecting the WSe$_2$ during the top mirror deposition, we fully preserve the optoelectronic behaviour of the device. Two bright cavity modes appear in the EL spectrum featuring Q-factors of 250 and 580 respectively: the first is attributed directly to the monolayer area, while the second is ascribed to the portion of emission guided outside the WSe$_2$ island. By embedding the EL device inside the microcavity structure, a significant modification of the directionality of the emitted light is achieved, with the peak intensity increasing by nearly two orders of magnitude at the angle of the maximum emission compared with the same EL device without the top DBR. Furthermore, the coupling of the WSe$_2$ EL to the cavity mode with a dispersion allows a tuning of the peak emission wavelength exceeding 35 nm (80 meV) by varying the angle at which the EL is observed from the microcavity. This work provides a route for the development of compact vertical-cavity surface-emitting devices based on van der Waals heterostructures.

description: We study the dynamics of a spectator Higgs field which stochastically evolves during inflation onto near-critical trajectories on the edge of a runaway instability. We show that its fluctuations do not produce primordial black holes (PBHs) in sufficient abundance to be the dark matter, nor do they produce significant second-order gravitational waves. First we show that the Higgs produces larger fluctuations on CMB scales than on PBH scales, itself a no-go for a viable PBH scenario. Then we track the superhorizon perturbations nonlinearly through reheating using the delta N formalism to show that they are not converted to large curvature fluctuations. Our conclusions hold regardless of any fine-tuning of the Higgs field for both the Standard Model Higgs and for Higgs potentials modified to prevent unbounded runaway.

Remittances

description: Remittances are transfers of money by foreign workers to their home countries. These remittance flows have been considered a very important source of finance for many developing countries accounting between 5-40% of the recipient country's GDP. This paper empirically examines whether remittance flows stabilize developing countries in the aftermath of sovereign defaults. To this end, we conduct Dynamic System Generalised Method of Moments (GMM) estimation techniques by Arellano and Bover (1995) and Blundell and Bond (1998) taking into account annual data cutting across 81 countries from 1990- 2010. We find that indeed remittances play a significant role in stabilizing a country which has defaulted on its sovereign debt. The findings of this study exhibit different results for different measures of default episodes. All in all our findings confirm yet another channel through which remittances can have a positive influence on recipient countries' economy since they support the hypothesis that the occurrence of a sovereign default spurs on an upsurge in remittances which play a stabilizing role.

This project collects randomly distributed 50'' x 50'' fields to investigate the cosmic shear effect on this scale. Analyzing the parallel observations having the Seyfert galaxy NGC625 as primary target, we recognized over the whole field of view a strong apparent tangential alignment of galaxy ellipticities towards the image center. The field shows several arclet-like features typical for images of massive galaxy clusters, but no obvious over-density of bright foreground galaxies. We also find a multiple image candidate. On the basis of the possible strong and weak lensing effect within the data, we discuss whether this could be compatible with a massive halo with no clear optical counterpart.

The theory is based on the Eilenberger equation to determine the order parameters and the Bogoliubov-de Gennes (BdG) equation to obtain the eigenenergies and the core magnetization. Within axisymmetric vortex configurations, we find several stable and metastable vortex configurations which depend on the strength of a magnetic field, similar to a $v$ vortex and $o$ vortex in $^3$He superfluids. We demonstrate that the $o$ vortex is the most stable axisymmetric vortex in the presence of a strong magnetic field, and we find two zero-energy Majorana fermion bound states in the $o$-vortex core. We show that the profiles of the core magnetization calculated using the BdG equation are drastically different from those calculated using only the order parameter profiles known before.

econometric analysis

description: Based on unique data from a representative computer-based survey among financial decision makers in Germany, this paper empirically examines the determinants of socially responsible investments (SRI). Our econometric analysis implies that the perceived financial performance of SRI matters for the shares of investments in SRI among all investments. However, our main result is that psychological motives, values, and norms like warm glow motives and ex-pectations of the social environment are even more relevant and thus have strong significant effects on SRI. This suggests that SRI investors gain strong non-financial utility from sustain-able investments. While the membership in Christian churches and the strength of Christian religiosity also seem to be positively correlated with SRI, these correlations become insignifi-cant if other psychological motives, values, and norms are included in the econometric analy-sis. Furthermore, a left-wing political orientation rather has significant negative effects on SRI. An explanation for this surprising result is the general aversion of a left-wing identifica-tion to the participation in stock markets, which is dominant in SRI.

Rare events in generalized Lévy Walks and the Big Jump principle

description: The prediction and control of rare events is an important task in disciplines that range from physics and biology, to economics and social science. The Big Jump principle deals with a peculiar aspect of the mechanism that drives rare events. According to the principle, in heavy-tailed processes a rare huge fluctuation is caused by a single event and not by the usual coherent accumulation of small deviations. We consider generalized Lévy walks, a class of stochastic processes with power law distributed step durations, which model complex microscopic dynamics in the single stretch. We derive the bulk of the probability distribution and using the big jump principle, the exact form of the tails that describes rare events. We show that the tails of the distribution present non-universal and non-analytic behaviors, which depend crucially on the dynamics of the single step. The big jump estimate also provides a physical explanation of the processes driving the rare events, opening new possibilities for their correct prediction.

description: This paper deals with the public acceptance of policies that pave the way for a more active role of family care assistants in long-term care provision. Family care assistants, i.e. non-relatives providing homecare services in the own private home of the care recipient, provide valuable help for adult children organizing long-term care for their parents. However, their support comes at the price of transferring more family-owned wealth to non-relatives. Based on a survey among German citizens, we provide empirical evidence on the factors that drive the support for a more active role of family care assistants. We find support to be higher among subjects who gave long-term care personally. Monetary self-interest is found to matter. In addition, we find evidence of a clear line of conflict: Citizens with alive parents are more likely to support a more active role of family care assistants than citizens whose parents are dead.

description: Inter-municipal cooperation (IMC) is promoted as a way in which small, fiscally weak munic-ipalities can cope with intensified interregional competition and demographic change. We pro-vide first evidence on citizens’ support for IMC using survey data from rural Germany. We cover different fields of public services and find the support for IMC to be lower for services where IMC implies intensified interaction with citizens from neighboring municipalities. The main research question asks whether citizens’ support for IMC is larger in municipalities that can – by the logic of normative theory – expect higher net benefits from IMC. The answer is largely negative: While support for IMC decreases in the travel-time to neighboring municipal-ities, we do not find the support for IMC to be higher among citizens in small and/or fiscally weak municipalities, nor do we find the available of suitable partners to matter. At the same time, citizens’ policy preferences strongly depends on individual-level factors. Believing that IMC reduces citizens’ influence and control reduces the support for IMC substantially. Trust in local politicians and a high degree of emotional attachment to the home municipality reduce citizens’ support for IMC.

description: We consider Schwinger type processes involving the creation of the charge and monopole pairs in the external fields and propose interpretation of these processes via corresponding brane configurations in Type IIB string theory. We suggest simple description of some new interesting nonperturbative processes like monopole/dyon transitions in the electric field and W-boson decay in the magnetic field using the brane language. Nonperturbative pair production in the strong coupling regime using the AdS/CFT correspondence is studied. The treatment of the similar processes in the noncommutative theories when noncommutativity is traded for the background fields is presented and the possible role of the critical magnetic field which is S-dual to the critical electric field is discussed.

description: Missing sentence generation (or sentence infilling) fosters a wide range of applications in natural language generation, such as document auto-completion and meeting note expansion. This task asks the model to generate intermediate missing sentences that can syntactically and semantically bridge the surrounding context. Solving the sentence infilling task requires techniques in natural language processing ranging from understanding to discourse-level planning to generation. In this paper, we propose a framework to decouple the challenge and address these three aspects respectively, leveraging the power of existing large-scale pre-trained models such as BERT and GPT-2. We empirically demonstrate the effectiveness of our model in learning a sentence representation for generation and further generating a missing sentence that fits the context.

Magnetic Interactions and Transport in (Ga,Cr)As

description: The magnetic, transport, and structural properties of (Ga,Cr)As are reported. Zincblende Ga$_{1-x}$Cr$_{x}$As was grown by low-temperature molecular beam epitaxy (MBE). At low concentrations, x$\sim$0.1, the materials exhibit unusual magnetic properties associated with the random magnetism of the alloy. At low temperatures the magnetization M(B) increases rapidly with increasing field due to the alignment of ferromagnetic units (polarons or clusters) having large dipole moments of order 10-10$^2$$μ_B$. A standard model of superparamagnetism is inadequate for describing both the field and temperature dependence of the magnetization M(B,T). In order to explain M(B) at low temperatures we employ a distributed magnetic moment (DMM) model in which polarons or clusters of ions have a distribution of moments. It is also found that the magnetic susceptibility increases for decreasing temperature but saturates below T=4 K. The inverse susceptibility follows a linear-T Curie-Weiss law and extrapolates to a magnetic transition temperature $θ$=10 K. In magnetotransport measurements, a room temperature resistivity of $ρ$=0.1 $Ω$cm and a hole concentration of $\sim10^{20}$ cm$^{-3}$ are found, indicating that Cr can also act as a acceptor similar to Mn. The resistivity increases rapidly for decreasing temperature below room temperature, and becomes strongly insulating at low temperatures. The conductivity follows exp[-(T$_1$/T)$^{1/2}$] over a large range of conductivity, possible evidence of tunneling between polarons or clusters.
