description: We study in detail certain brane solutions with compact extra dimensions M^4 x K in the IKKT matrix model, with K being a two-dimensional rotating torus embedded in R^6. We focus on the compactification moduli and the fluctuations of K \subset R^6 and their physical significance. Mediated by the Poisson tensor, they contribute to the effective 4-dimensional metric on the brane, and thereby become gravitational degrees of freedom. We show that the zero modes corresponding to the global symmetries of the model lead to Ricci-flat 4-dimensional metric perturbations, wherever the energy-momentum tensor vanishes. Their coupling to the energy momentum tensor depends on the extrinsic curvature of the brane.

description: 1. Aceria capsellae (Nalepa 1890)
 Nalepa 1890a— Anz. kais. Akad. Wiss., Math-Natur Kl., Wien, 27(1): 2 (nomen nudum); Nalepa 1890b— Sitzb. kaiser. Akad. Wiss. Math.-Naturwiss., Wien, 99(2): 66 no. 23 (nomen nudum); Nalepa 1891 — Nova Acta Leop. Akad., 55(6): 371–373 (no fig.).
 Type data. Capsella bursa-pastoris (L.) Medik. (= C. Bursa pastoris Mönch. as reported by Nalepa 1890a; 1929), Chinese cress, shepherd's purse; collection locality was not stated by the author even though Austria is presumed.
 General distribution. Palaearctic (presumed to be only Austria).
 Relation to the host. This mite was associated with the deformation of flowers.
 Remarks. No morphological description is available for this species. Most reports consist of catalogue citations. However, Nalepa (1891) compared plant deformation and mites, and established that the flower abnormalities on Camelina sativa (L.) Crantz, Capsella bursa-pastoris, Cardaria draba (L.) Desv. (originally listed as Lepidium draba L.) and Descurainia sophia (L.) Webb ex Prantl (originally listed as Sisymbrium sophia L.), were caused by the same mite or, at most, its varieties. On the basis of quite clear morphological differences in mite populations, Nalepa linked Aceria longior to C. sativa and D. sophia; A. longior var. capsellae to C. bursa-pastoris and A. longior var. drabae to C. draba. Later, A. capsellae was made a junior synonym of A. drabae (Nalepa 1898; 1929). Amrine and Stasny (1994) elevated this species name to the rank of species but they were doubtful about the real taxonomic status of A. capsellae. Without any further details allowing for the clear characterisation of this species, its synonymy with A. drabae was continued in the Fauna Europaea checklist by de Lillo (2004).

description: In this work, we consider the existence of global solution and the exponential decay of a nonlinear porous elastic system with time delay. The nonlinear term as well as the delay acting in the equation of the volume fraction. In order to obtain the existence and uniqueness of a global solution, we will use the semigroup theory of linear operators and under a certain relation involving the coefficients of the system together with a Lyapunov functional, we will establish the exponential decay of the energy associated to the system.

description: Energy in a multipartite quantum system appears from an operational perspective to be distributed to some extent non-locally because of correlations extant among the system's components. This non-locality allows users to transfer, in effect, locally accessible energy between sites of different system components by LOCC (local operations and classical communication). Quantum energy teleportation is a three-step LOCC protocol, accomplished without an external energy carrier, for effectively transferring energy between two physically separated, but correlated, sites. We apply this LOCC teleportation protocol to a model Heisenberg spin particle pair initially in a quantum thermal Gibbs state, making temperature an explicit parameter. We find in this setting that energy teleportation is possible at any temperature, even at temperatures above the threshold where the particles' entanglement vanishes. This shows for Gibbs spin states that entanglement is not fundamentally necessary for energy teleportation; correlation other than entanglement can suffice. Dissonance---quantum correlation in separable states---is in this regard shown to be a quantum resource for energy teleportation, more dissonance being consistently associated with greater energy yield. We compare energy teleportation from particle A to B in Gibbs states with direct local energy extraction by a general quantum operation on B and find a temperature threshold below which energy extraction by a local operation is impossible. This threshold delineates essentially two regimes: a high temperature regime where entanglement vanishes and the teleportation generated by other quantum correlations yields only vanishingly little energy relative to local extraction and a second low-temperature teleportation regime where energy is available at B only by teleportation.

description: The bondage number of a graph is the smallest number of its edges whose removal results in a graph having a larger domination number. We provide constant upper bounds for the bondage number of graphs on topological surfaces, improve upper bounds for the bondage number in terms of the maximum vertex degree and the orientable and non-orientable genera of the graph, and show tight lower bounds for the number of vertices of graphs 2-cell embeddable on topological surfaces of a given genus. Also, we provide stronger upper bounds for graphs with no triangles and graphs with the number of vertices larger than a certain threshold in terms of the graph genera. This settles Teschner's Conjecture in positive for almost all graphs.

description: Another morphological substrate of cognitive impairment in hypertension may be diffuse injury of this white matter, cortical atrophy, and cerebral hypoperfusion caused by specific structural changes in small intracerebral arterioles. Cortical (granular) atrophy of the hemispheres develops due to the death of neurons, which explains the functional disorders. Several small focal lesions in the deep parts of the brain, spongiosis of the white matter, impairment of higher mental functions lead to scattering of brain structures, particularly the temporal, parietal, as well as limbic-reticular complex structures of the frontal regions.
Experienced clinicians understanding and approach to treatment with male survivors of child sexual abuse

description: The number of males abused sexually as children are significant and while the awareness of the needs of this population has increased, the process in treatment has not been sufficiently examined. The purpose of this study was to explore experienced clinicians' approach and understanding within treatment with adult male survivors of child sexual abuse. A qualitative research design was utilized, using purposeful expert sampling procedures. In this study, data was collected from phone interviews with five participants who were identified as highly experienced clinicians in the area of male survivors of child sexual abuse treatment. Using qualitative methods within phenomenological inquiry, several themes emerged as clinical considerations and implications within the assessment, treatment and termination phases of therapy with male survivors of child sexual abuse; respect for client's direction and pace, multi-focus in treatment, somatic interventions, safety to address feelings of shame and inadequacy, and insight used to understand latent effects of the abuse.
Sentence Processing at the Interfaces – Dependency Relations Across Levels of Representation

description: One of the hallmark features of language is that linguistic elements (from morphemes to words and phrases) commonly relate to each other, thus instantiating a dependency relation between different parts of the linguistic input. Within psycholinguistics, key questions have been how comprehenders keep track of such dependencies and what (top-down and bottom-up) cognitive mechanisms are engaged during the resolution of dependency relations. In this thesis, I investigate the processing and comprehension of three different types of dependency relations for a state-of-the-art perspective onto the shared, and the unique, mechanisms engaged to resolve linguistic dependency relations. The thesis has two major components: In its first part, focusing on expectation-based processing mechanisms, it provides novel empirical evidence for the engagement of expectations in adults’ processing of dependencies at various levels of linguistic representation—from the syntactic dependency between German determiners and relative clauses to the discourse-level dependency relation in concessive discourse relations. In its second part, focused on the particular dependency relation between polarity sensitive expressions and their (anti-)licenser, the thesis combines theoretical and empirical linguistic perspectives to illuminate the mechanisms involved in the licensing, comprehension, processing, and acquisition of polarity sensitive expressions. Therein, the included studies demonstrate comprehenders’ immediate sensitivity to semantic and pragmatic properties of the sentential contexts in which negative polarity items appear, and attest to dependency-specific memory effects in adults’ processing and comprehension. From the developmental perspective, these findings are complemented by a study showing that the acquisition of polarity sensitive expressions extends at least into early adolescence, with substantial variation that may be due to pragmatic development and input-related differences. The combined findings from both sections of this thesis have impact on linguistic theory and psycholinguistics alike.

 Type data. Cardamine bellidifolia L., alpine bitter cress; Saana, Lapponia enontekiöensis, Finland.
 General distribution. Palaearctic (only Finland).
 Relation to the host. Upward rolling of the leaf margin giving the lamina a narrow and distorted appearance; the plant remains sterile.
 Remarks. Roivainen (1950) set A. cardaminesbellidifoliae as a synonym of A. drabae and this was underlined again by Liro & Roivainen (1951). The mite described by Liro is provided with complete median and admedian lines, granules on the lateral sides of the prodorsal shield while no granules were depicted in the median field. Amrine & Stasny (1994) elevated this name to the rank of species but they were doubtful about the real taxonomic status of A. cardaminisbellidifoliae.

description: Over the years, Machine Learning models have been successfully employed on neuroimaging data for accurately predicting brain age. Deviations from the healthy brain aging pattern are associated to the accelerated brain aging and brain abnormalities. Hence, efficient and accurate diagnosis techniques are required for eliciting accurate brain age estimations. Several contributions have been reported in the past for this purpose, resorting to different data-driven modeling methods. Recently, deep neural networks (also referred to as deep learning) have become prevalent in manifold neuroimaging studies, including brain age estimation. In this review, we offer a comprehensive analysis of the literature related to the adoption of deep learning for brain age estimation with neuroimaging data. We detail and analyze different deep learning architectures used for this application, pausing at research works published to date quantitatively exploring their application. We also examine different brain age estimation frameworks, comparatively exposing their advantages and weaknesses. Finally, the review concludes with an outlook towards future directions that should be followed by prospective studies. The ultimate goal of this paper is to establish a common and informed reference for newcomers and experienced researchers willing to approach brain age estimation by using deep learning models

description: We use a semantic interpretation to investigate the problem of defining an expressive but decidable type system with bounded quantification. Typechecking in the widely studied System Fsub is undecidable thanks to an undecidable subtyping relation, for which the culprit is the rule for subtyping bounded quantification. Weaker versions of this rule, allowing decidable subtyping, have been proposed. One of the resulting type systems (Kernel Fsub) lacks expressiveness, another (System Fsubtop) lacks the minimal typing property and thus has no evident typechecking algorithm. We consider these rules as defining distinct forms of bounded quantification, one for interpreting type variable abstraction, and the other for type instantiation. By giving a semantic interpretation for both in terms of unbounded quantification, using the dinaturality of type instantiation with respect to subsumption, we show that they can coexist within a single type system. This does have the minimal typing property and thus a simple typechecking procedure. We consider the fragments of this unified type system over types which contain only one form of bounded quantifier. One of these is equivalent to Kernel Fsub, while the other can type strictly more terms than System Fsubtop but the same set of beta-normal terms. We show decidability of typechecking for this fragment, and thus for System Fsubtop typechecking of beta-normal terms.

description: In an attempt to utilize spectrum resources more efficiently, protocols sharing licensed spectrum with unlicensed users are receiving increased attention. From the perspective of cellular networks, spectrum underutilization makes spatial reuse a feasible complement to existing standards. Interference management is a major component in designing these schemes as it is critical that licensed users maintain their expected quality of service. We develop a distributed dynamic spectrum protocol in which ad-hoc device-to-device users opportunistically access the spectrum actively in use by cellular users. First, channel gain estimates are used to set feasible transmit powers for device-to-device users that keeps the interference they cause within the allowed interference temperature. Then network information is distributed by route discovery packets in a random access manner to help establish either a single-hop or multi-hop route between two device-to-device users. We show that network information in the discovery packet can decrease the failure rate of the route discovery and reduce the number of necessary transmissions to find a route. Using the found route, we show that two device-to-device users can communicate with a low probability of outage while only minimally affecting the cellular network, and can achieve significant power savings when communicating directly with each other instead of utilizing the cellular base station.

Blameworthiness and dangerousness: An analysis of violent female capital offenders in the United States and China
Creators: name: LaHaie, Courtney Brooke
Publisher: name: University of Nevada, Las Vegas
Year: 2010

description: The United States and China represent two of the leading nations that retain the death penalty in both law and practice. Research suggests that judges' sentencing decisions are based primarily on two factors, blameworthiness and dangerousness. Studies involving gender and sentencing in capital punishment cases tend to provide inconsistent findings. The current study uses case narratives to examine the direct and conjunctive effects of various factors on the sentencing decisions of violent female capital offenders in the United States and China. The findings suggest that the concepts of blameworthiness and dangerousness are distinctly defined in the United States and China. The study proposes that the differences observed in the capital offense sentencing practices of these two countries can be attributed to the distinct political, legal and social systems of the United States and China.

description: The specifics of data layout can be important for the efficiency of functional programs and interaction with external libraries. In this paper, we develop a type-theoretic approach to data layout that could be used as a typed intermediate language in a compiler or to give a programmer more control. Our starting point is a computational interpretation of the semi-axiomatic sequent calculus for intuitionistic logic that defines abstract notions of cells and addresses. We refine this semantics so addresses have more structure to reflect possible alternative layouts without fundamentally departing from intuitionistic logic. We then add recursive types and explore example programs and properties of the resulting language.

description: Οι αιμοσφαιρινοπάθειες είναι μια ομάδα νόσων που είναι ιδιαίτερα συχνή παγκοσμίως. Αυτές χωρίζονται ανάλογα με το αποτέλεσμα της μετάλλαξης που τις προκαλεί: αν η με-τάλλαξη επηρεάζει την ποσότητα της αιμοσφαιρίνης που παράγεται (θαλασσιαμίες) ή την ποιότητα αυτής (ποιοτικές διαταραχές της δομής αιμοσφαιρίνης). Στην παρούσα ερ-γασία σκοπός ήταν να παρουσιαστούν οι αιμοσφαιρινοπάθειες, ο μηχανισμός ανάπτυ-ξης αυτών και οι διαθέσιμες θεραπευτικές επιλογές. Αρχικά παρουσιάζεται η δομή και η λειτουργία της αιμοσφαιρίνης, στη συνέχεια ο γενικός μηχανισμός ανάπτυξης των αιμο-σφαιρινοπαθειών και παρουσιάζονται επιδημιολογικά στοιχεία των φορέων μεταλλαγ-μένων αιμοσφαιρινών σε διάφορες χώρες του κόσμου. Στη συνέχεια γίνεται ταξινόμηση των αιμοσφαιρινοπαθειών σε κατηγορίες και σύντομη αναφορά στο γονότυπο και την κλινική και φαινοτυπική εικόνα αυτών. Το κύριο μέρος της εργασίας χωρίζεται σε δύο κεφάλαια όπου παρουσιάζονται οι ποσοτικές και ποιοτικές αιμοσφαιρινοπάθειες αντί-στοιχα. Οι ποσοτικές αιμοσφαιρινοπάθειες -ή αλλιώς θαλασσαιμικά σύνδρομα- χωρίζο-νται σε α-θαλασσαιμίες και β-θαλασσαιμίες, ανάλογα με το ποια γονίδια επηρεάζονται. Και στις δύο περιπτώσεις παρατηρείται σημαντική ποικιλομορφία ως προς τη βαρύτητα της νόσου. Η πιο συχνή ποιοτική αιμοσφαιρινοπάθεια είναι η δρεπανοκυτταρική νόσος που προκαλείται από υποκατάσταση αμινοξέος στο έκτο υπόλειμμα της υπομονάδας β-σφαιρίνης (β6-Glu→Val). Άλλες ποιοτικές μεταλλάξεις που οδηγούν σε αιμοσφαιρινοπά-θεια προκαλούν αλλαγή στη σταθερότητα της αιμοσφαιρίνης, τη συγγένεια στο οξυγόνο, την παραγωγή μεθαιμοσφαιρίνης και τη μεταμεταφραστική τροποποίηση των αιμο-σφαιρινών. Σε ήπιες μορφές συνήθως δεν απαιτείται η χορήγηση κάποιες θεραπείας ή σε ορισμένες περιπτώσεις μπορεί να χορηγούνται συμπληρώματα φυλλικού οξέος ή/και σιδήρου. Σε πιο βαριές περιπτώσεις πραγματοποιούνται μεταγγίσεις. Ανάλογα με το αν επηρεάζονται άλλα όργανα και συστήματα μπορεί να χορηγείται συμπληρωματική συ-μπτωματική θεραπεία. Ακόμα, έχουν καταγραφεί και επίκτητες αιμοσφαιρινοπάθειες οι οποίες αναφέρονται. Σε αυτή την περίπτωση για τη θεραπεία συνήθως επαρκεί η απο-μάκρυνση του παράγοντα που προκάλεσε την αιμοσφαιρινοπάθεια, ενώ σε οξείες περι-πτώσεις μπορεί να χρειαστούν και πιο δραστικές θεραπείες, όπως μετάγγιση.

Αποτελέσματα: Η αυτόλογη μετάγγιση γίνεται ολοένα και πιο αποδεκτή από τη επιστημονική κοινότητα, ενώ και ένας μεγάλος αριθμός ασθενών και των φροντιστών τους έχει ενημερωθεί για τα οφέλη αυτής της τεχνικής. Στα οφέλη της συμπεριλαμβάνεται η αποφυγή της εξάπλωσης ασθενειών μέσω του αίματος, αλλά και την αντιμετώπιση αναγκών αίματος σε περιπτώσεις όπου δεν υπάρχει πρόσβαση στον τύπο αίματος που απαιτείται. Συμπεράσματα: Αν και η τεχνική της αυτόλογης μετάγγισης αίματος χρησιμοποιείται πλέον για την αντιμετώπιση περιπτώσεων αναιμίας και αιμορραγίας σε χειρουργικές επεμβάσεις, είναι σημαντικό να πραγματοποιηθούν περαιτέρω μελέτες με σκοπό τη διερεύνηση αποτελεσματικότητας και της ασφάλειας των μεθόδων αυτόλογης μετάγγισης αίματος, αλλά και τη σχέση κόστους – αποτελέσματος.

description: In this paper, it is proved that (strict) copositivity of a symmetric tensor $\mathcal{A}$ is equivalent to the fact that every principal sub-tensor of $\mathcal{A}$ has no a (non-positive) negative $H^{++}$-eigenvalue. The necessary and sufficient conditions are also given in terms of the $Z^{++}$-eigenvalue of the principal sub-tensor of the given tensor. This presents a method of testing (strict) copositivity of a symmetric tensor by means of the lower dimensional tensors. Also the equivalent definition of strictly copositive tensors is given on entire space $\mathbb{R}^n$.

Category-Graded Algebraic Theories and Effect Handlers
Creators: name: Sanada, Takahiro
Publisher: name: arXiv
Year: 2022
Subjects: subject: Programming Languages (cs.PL)
subject: FOS: Computer and information sciences

description: We provide an effect system CatEff based on a category-graded extension of algebraic theories that correspond to category-graded monads. CatEff has category-graded operations and handlers. Effects in CatEff are graded by morphisms of the grading category. Grading morphisms represent fine structures of effects such as dependencies or sorts of states. Handlers in CatEff are regarded as an implementation of category-graded effects. We define the notion of category-graded algebraic theory to give semantics of CatEff and prove soundness and adequacy. We also give an example using category-graded effects to express protocols for sending receiving typed data.
Special event recycling: The future of UNLV's recycling program
Creators: name: Baker, Katherine A.
Publisher: name: University of Nevada, Las Vegas
Year: 2000

description: The current recycling program on the University of Nevada Las Vegas (UNLV) campus does not have a special event recycling aspect. The purpose of this study was to develop a special event recycling program and make recommendations of how to effectively implement it on the UNLV campus. In order to develop this special event recycling program data was collected through surveys and a pilot study. The data collected was then used to formulate recommendations. Recycling two different kinds of events, a walk and a concert tested those recommendations. Waste stream analyses were done on each event. The waste stream diversion rates were determined to be significantly better than the diversion rate of the pilot study.

description: A bibliometric analysis of the Scopus database was performed to identify research trends related to cross-laminated timber (CLT) from 2006, when the earliest publication was found, to 2018. The analysis revealed a rapidly increasing number of annual publications, great contribution of conference papers to the total scientific production regarding this topic, a high degree of transdisciplinary collaboration, and a particularly remarkable contribution by Canada and Italy. The applied bibliometric network analysis was useful to determine the strategic diagram of topic clusters and their evolution through time. Number of cited papers and analysis of frequent keywords provided insight to identify the most relevant research topics: the seismic performance of CLT structures, and the mechanical properties of connections between different CLT substructures.

description: In this paper we characterize those accessible $\mathcal V$-categories that have limits of a specified class. We do this by introducing the notion of companion $\mathfrak C$ for a class of weights $Ψ$, as a collection of special types of colimit diagrams that are compatible with $Ψ$. We then characterize the accessible $\mathcal V$-categories with $Ψ$-limits as those accessibly embedded and $\mathfrak C$-virtually reflective in a presheaf $\mathcal V$-category, and as the $\mathcal V$-categories of $\mathfrak C$-models of sketches. This allows us to recover the standard theorems for locally presentable, locally multipresentable, and locally polypresentable categories as instances of the same general framework. In addition, our theorem covers the case of any weakly sound class $Ψ$, and provides a new perspective on the case of weakly locally presentable categories.

description: 6. Aceria longior (Nalepa 1891).
 Nalepa 1891 — Nova Acta Leop. Akad., 55(6): 371–373, pl. 1 figs 1‒2.
 Type data. Camelina sativa (L.) Crantz, gold of pleasure; collecting locality was not stated by the author even though Austria is presumed.
 Alternative hosts. Alyssum alyssoides (L.) L. (previously listed as Alyssum calicynum L.), Berteroa incana (L.) DC., C. bursa-pastoris, C. draba, Daucus carota L. (family Umbelliferae), D. sophia (previously listed as S. sophia).
 General distribution. Palaearctic (Austria; Bosnia Herzegovina; Hungary)
 Relation to the host. This species was associated with flower greening and deformation.
 Remarks. Nalepa (1891) at first described either A. longior or its two varieties drabae and capsellae. Later, he elevated drabae to the rank of species and synonymised A. longior and A. capsellae with it (Nalepa 1929). Amrine and Stasny (1994) listed this species as a junior synonym of A. drabae and this synonymy was retained in the Fauna Europaea checklist by de Lillo (2004). Examining carefully the drawings of Nalepa (1891d), a few differences can be observed on the prodorsal shield pattern such as a complete submedian line ending on the rear shield margin between the admedian line and the sc tubercles.

description: This paper aims to study the mechanical, thermal and hygroscopic behavior of Okan (Cylicodiscus gabunensis) and Ayous (Triplochiton scleroxylon), two African hardwood species grown in southern Cameroon. The mechanical characterization of wood at 10%, 15%, 20%, 25% and 30% was investigated using tensile and bending tests. The thermal parameters were measured at the same moisture content levels by using the asymmetrical hot plate method. Sorption isotherms were obtained using the static gravimetric method. Mechanical properties decreased with moisture content. Okan wood, which Guitard and Brazilian models was not suitable for, presented very good properties compared to Ayous wood. Its flexural strength varied between 100 and 140 MPa and was 2.5 times higher than Ayous wood. Thermal conductivity increased with moisture content and was ranged from 0.1 to 0.56 W/mK. There was no significant difference between the radial thermal conductivities of the two species. The volumetric heat capacity was not influenced by the heat flow and the species. Experimental data showed a good fitting with the GAB model concerning sorption isotherms. Okan wood was less hygroscopic than Ayous wood. The annual equilibrium moisture content of the two species was determined and the cities of Bafoussam and Douala presented the best stabilization trend.
Anomalous magnetoresistance and magnetocaloric properties of NdRu2Ge2

description: It is found that the polycrystalline NdRu2Ge2 undergoes two successive magnetic transitions at Tt=10 K and TN=19 K. Evidence of metamagnetic transition is detected in the magnetization isotherm data in the antiferromagnetic regime. Temperature dependence of magnetoresistance (MR) show that the relative magnitudes of MR at TN and Tt change considerably as the field is increased from 10 kOe to 30 kOe. Moreover, the MR is found to be positive below 9 K for 30 kOe field although the material is ferromagnetic at these temperatures. The highest value of negative MR near TN is about 42% in a field of 30 kOe, while the positive MR is about 35 % at 3 K in a field of 50 kOe. Like MR, the magnetocaloric effect at TN and Tt also shows anomalous behavior. The relative magnitudes of MCE at these temperatures are found to change with increase in field. It appears that the high field (>10 kOe) magnetic state below TN is complex, giving rise to some antiferromagnetic-like fluctuations, affecting the MR and MCE behavior.

description: Constraints are placed on the spin-independent interaction cross section of dark matter with regular matter by refining two methods. First, dark matter--cosmic ray interactions are considered, wherein cosmic ray protons collide with dark matter to contribute to the gamma ray sky. This constraint is developed using the NFW and Moore dark matter density profiles and new data from the Fermi gamma ray space telescope. Second, the Earth capture scenario is considered, wherein particles that are captured self-annihilate at Earth's center, thus adding to its internal heat flow. The constraint presented here is developed based on analysis of the drift time of dark matter particles through Earth, modeled as a core composed of iron and a mantle composed of oxygen with linear density gradients between layers. An analysis of the cosmic ray constraint (which rules out dark matter--regular matter interaction cross sections greater than its value) shows that it overlaps significantly with the Earth drift time constraint (which rules out cross sections smaller than its value), closing the window on strongly interacting dark matter particles up to a mass of about 10^{17} GeV when combined with other exclusions.

description: How can social scientists design and focus their research to ensure they can answer questions using existing data? How do researchers find relevant data for a specific project? In this webinar, three research fellows working on the Infra4NextGen project share their experience in navigating the wealth of publicly available survey data. The webinar covers strategies to design a social research question and focus on how to answer it. This considers both a bottoms up approach (what data is available in this field to study the concepts of interest?) and a top-down one (where and how can I find relevant data for a specific topic?)

description: A recurring problem in game semantics is to enforce uniformity in strategies. Informally, a strategy is uniform when the Player's behaviour does not depend on the particular indexing of moves chosen by the Opponent. In game semantics, uniformity is used to define a resource modality !, that can be exploited for the semantics of programming languages. In this paper we give a new account of uniformity for strategies on event structures. This work is inspired by an older idea due to Melliès, that uniformity should be expressed as "bi-invariance" with respect to two interacting group actions. We explore the algebraic foundations of bi-invariance, adapt this idea to the language of event structures and define a general notion of uniform strategy in this context. Finally we revisit an existing approach to uniformity, and show how this arises as a special case of our constructions.

description: The scope of this article is an inter-industry study of the Swedish Wood Manufacturing Sector (WMS), examined from the perspective of the Structure-Conduct-Performance (SCP) paradigm in the theoretical field of Industrial Organization. The four research questions are: (1) identify the industries within the sector, (2) construct a contextually adapted SCP model and form the basis for hypotheses of relationships between the different variables in the model, (3) establish quantitative correlations between the variables, and finally (4) present a basically qualitative, explanatory interpretive analysis. The empirical investigation is a total population study of 311 firms. Nine industries are identified, and an SCP model is presented including four explanatory variables – exposure to international competition, value-added scope, domestic demand growth potential and (domestic industry) seller concentration – and two performance variables – industry profitability (ROA) and industry growth. The combined qualitative and quantitative explanatory analysis identifies some important relationships in the SCP model. The most prominent findings are the strong negative relationships between exposure to international competition and industry profitability and industry growth. Another finding is that strong positive relationships are found between the degree of value-added scope and industry profitability and industry growth.
