description: In this thesis, we reconsider some continuous-time stochastic control problems in finance and insurance. To incorporate some well-documented behavioural features of human beings, we consider the situation where the discounting is non-exponential. This situation is far from trivial and renders the optimisation problem to be a non-standard one, namely, a time-inconsistent stochastic control problem since Bellman’s principle of optimality does not hold. In this situation, the optimal control is time-inconsistent, namely, a strategy that is optimal for the initial time may not be optimal later. Three self-contained papers are included in this thesis, each of which is concerned with one specific optimisation problem. We analyse these problems within a game theoretic framework and try to find the time-consistent equilibrium strategies for each problem. In Chapter 2, we study the dividend maximisation problem in a diffusion risk model and try to find an equilibrium strategy within the class of feedback controls. We assume that the dividends can only be paid at a bounded rate and consider the ruin risk in the dividend problem. We obtain an equilibrium HJB equation and verification theorem for a general discount function, and get closed-form solutions in two examples. In Chapter 3, we investigate the defined benefit pension problem, where the aim of the decision-maker is to minimise two types of risks: the contribution rate risk and the solvency risk, by considering a quadratic performance criterion. In our model, we assume that the benefit outgo is constant and the pension fund can be invested in a riskfree asset and a risky asset whose return follows a geometric Brownian motion. We characterise the time-consistent equilibrium strategy and value function in terms of the solution of a system of integral equations. The existence and uniqueness of the solution is verified and the approximation of the solution is obtained. In Chapter 4, we consider the consumption-investment problem with logarithmic utility in a non-Markovian framework. The coefficients in our model are assumed to be adapted stochastic processes. We first study an N-person differential game and adopt a martingale method to solve an optimisation problem of each player and characterise their optimal strategies and value functions in terms of the unique solutions of BSDEs. Then by taking the limit, we show that a time-consistent equilibrium consumption-investment strategy of the original problem consists of a deterministic function and the ratio of the market price of risk to the volatility, and the corresponding equilibrium value function can be characterised by the unique solution of a family of BSDEs parameterised by a time variable.

description: The observation of a sharp spectral feature in the gamma-ray sky would be one of the cleanest ways to identify dark matter and pinpoint its properties. Over the years a lot of attention has been paid to two specific features, namely gamma-ray lines and internal bremsstrahlung. Here, we explore a third class of spectral signatures, box-shaped gamma-ray spectra, that naturally arise in dark matter cascade annihilations or decays into intermediate particles that in turn decay into photons. Using Fermi-LAT data, we derive constraints on the dark matter parameter space for both annihilating and decaying dark matter, and show explicitly that our limits are competitive to strategies employing standard spectral features. More importantly, we find robust limits even in the case of non-degenerate dark matter and intermediate particle masses. This result is particularly relevant in constraining dark matter frameworks with gamma-ray data. We conclude by illustrating the power of box-shaped gamma-ray constraints on concrete particle physics scenarios.

description: Floquet topological insulators are topological phases of matter generated by the application of time-periodic perturbations on otherwise conventional insulators. We demonstrate that spatial variations in the time-periodic potential lead to localized quasi-stationary states in two-dimensional systems. These states include one-dimensional interface modes at the nodes of the external potential, and fractionalized excitations at vortices of the external potential. We also propose a setup by which light can induce currents in these systems. We explain these results by showing a close analogy to px+ipy superconductors.

title: Domestic Dislocations: Home-loss and the Second World War in Urban Britain
Creators: name: Mallon, Jacinta
Publisher: name: University of Kent
Year: 2025

description: The urban home in Second World War Britain was a space increasingly exposed to disruption and destruction. Most obviously, this period saw an extension of aerial warfare, which shook domestic lives out of their routines and often threatened to dismantle them entirely. At the same time, emergency powers of requisitioning gave the state unprecedented control over private property and allowed the government to take possession of dwellings, therefore constructing another means for citizens to be dislocated from their homes. This thesis examines how the threat or reality of losing one's home in either - or both - of these ways was understood and navigated by urban citizens between 1914 and 1960. 

Antecedent experiences of air raids and requisitioning during the First World War are explored first, highlighting the ways in which this conflict laid the groundwork for later understandings of wartime home-loss. The central chapters of the thesis are concerned with the Second World War itself, considering how the arrival of this conflict disrupted the domestic sphere more broadly; how affective responses to the loss of this site were constructed and policed; and how different experiences of loss were understood in relation to one another. Finally, the postwar legacies of home-loss are traced up to 1960, the point at which requisitioning came to a legal end. Throughout the thesis, emotional and spatial methodologies are employed in order to elucidate the relationship between citizens and their dwellings. 

It is argued that the loss of home - whether at the hands of the enemy, or of one's own state - mattered deeply in wartime Britain. Practically, economically, politically, and emotionally, this was an event with significant ramifications for both individuals and wider society. Accordingly, it was also an experience which bled into broader social and political debates, and in particular those that dissected the shifting nature of citizenship. This thesis thus highlights the utility of using the home - and its loss - as an interpretive lens through which to examine the urban experience of war on the British home front. In so doing, it charts a path by which we might better understand how individuals, communities, and governments prepare themselves for the possibility of conflict and violence, and how they navigate the inherent vulnerability of intimate, everyday spaces to modern forms of war.

Subjects: menstruation, gender equality

description: EcoFeminita (https://ecofeminita.com/) is a non-profit civil association which aims to show and address gender inequality by disseminating data, statistics, academic content and original research targeting all audiences. For this talk, I’d like to present our report called “How much does it cost to menstruate?”, which estimates the annual cost of menstrual management products —pads and tampons— based on data obtained through web scraping the government's open-data source Precios Claros (https://www.preciosclaros.gob.ar/). This report is done in the context of the #MenstruAcción campaign, which attempts to accomplish two main goals. Firstly, to expose the importance of providing menstrual management products for free, since they are a basic healthcare element to which not all the population have access. Secondly, to break down the menstruation taboo and promote research and socialization of data about this topic. My talk will address the main demands of the campaign, and the importance of using data in order to fight inequality. I will also explain our open-data methodology, the results of our report, and the recent challenges we’ve been facing due to the lack of transparency of Precios Claros.

description: Our aims were to: (1) estimate the prevalence of essential tremor (ET) in a community-based study in northern Manhattan, New York, N.Y., USA; (2) compare prevalence across ethnic groups, and (3) provide prevalence estimates for the oldest old. Methods: This study did not rely on a screening questionnaire. Rather, as part of an in-person neurological evaluation, each participant produced several handwriting samples, from which ET diagnoses were assigned. Results: There were 1,965 participants (76.7 ± 6.9 years, range = 66–102 years); 108 had ET [5.5%, 95% confidence interval (CI) = 4.5–6.5%]. Odds of ET were robustly associated with Hispanic ethnicity versus white ethnicity [odds ratio (OR) = 2.19, 95% CI = 1.03–4.64, p = 0.04] and age (OR = 1.14, 95% CI = 1.03–1.26, p = 0.01), i.e. with every 1 year advance in age, the odds of ET increased by 14%. Prevalence reached 21.7% among the oldest old (age ≥95 years). Conclusions: This study reports a significant ethnic difference in the prevalence of ET. The prevalence of ET was high overall (5.5%) and rose markedly with age so that in the oldest old, more than 1 in 5 individuals had this disease.

Multilingual communication the role of gaze, physical contact, and time perception and organization in intercultural interactions
Creators: name: Facciani, Chiara

Publisher: name: De Europa
Year: 2023

description: Research on multilingualism and intercultural communication has been gaining large recognition. However, a number of subject areas are still largely underexplored. For example, verbal communication is prioritised while little emphasis is given to the multimodality of multilingual and multicultural interactions. Also, while some studies focus on the role of gestures in intercultural communication, elements such as gaze, physical contact, and time are far less researched. However, the lack of attention to some non-verbal elements can create misunderstandings, particularly when people share a spoken code only partially, as is the case with non-native speakers. Thus, non-verbal language should be given a wider scope in multilingual and intercultural research. This paper is a preliminary investigation of how intercultural differences in the use and interpretation of non-verbal codes of communication can affect interactions between migrants and social workers in Italy. The focus is on gaze, physical contact, and time perception and organization. The paper provides a qualitative analysis of focus groups and online questionnaires submitted to social workers working in northern Italy and supporting migrants in their daily integration in the society. The results show that the use and interpretation of gaze, physical contact and time vary considerably depending on the individual migrant as well as their culture of origin. Considerations are drawn on the extent to which cultural differences in the interpretation of non-verbal codes can create misunderstandings and undermine migrants’ integration.

description: Blood concentrations of harmane, a tremor-producing neurotoxin, are elevated in essential tremor (ET). Harmane is also a comutagen. Using a case-control design, we compared the prevalence of cancer in ET cases vs. controls, and determined whether blood harmane concentrations are elevated among ET cases with cancer. 66/267 (24.7%) ET cases vs. 55/331 (16.6%) controls had cancer (adjusted OR 1.52, 95% CI 1.01 — 2.30, P = 0.04). Among specific cancer types, colon cancer was more prevalent in ET cases than controls (2.6% vs. 0.6%, P = 0.04). Log blood harmane concentration was higher in ET cases vs. controls (P = 0.02) and in participants with vs. without cancer (P = 0.02). Log blood harmane concentration was highest in ET cases with cancer when compared with other groups (P = 0.009). These links between cancer and ET and between high blood harmane and cancer in ET deserve further study.

description: Non-biased systematic sampling using the principles of stereology provides accurate quantitative estimates of objects within neuroanatomic structures. However, the basic principles of stereology are not optimally suited for counting objects that selectively exist within a limited but complex and convoluted portion of the sample, such as occurs when counting cerebellar Purkinje cells. In an effort to quantify Purkinje cells in association with certain neurodegenerative disorders, we developed a new method for stereologic sampling of the cerebellar cortex, involving calculating the volume of the cerebellar tissues, identifying and isolating the Purkinje cell layer and using this information to extrapolate non-biased systematic sampling data to estimate the total number of Purkinje cells in the tissues. Using this approach, we counted Purkinje cells in the right cerebella of four human male control specimens, aged 41, 67, 70 and 84 years, and estimated the total Purkinje cell  number for the four entire cerebella to be 27.03, 19.74, 20.44 and 22.03 million cells, respectively. The precision of the method is seen when comparing the density of the cells within the tissue: 266,274, 173,166, 167,603 and 183,575 cells/cm3, respectively. Prior literature documents Purkinje cell  counts ranging from 14.8 to 30.5 million cells. These data demonstrate the accuracy of our approach. Our novel approach, which offers an improvement over previous methodologies, is of value for quantitative work of this nature. This approach could be applied to morphometric studies of other similarly complex tissues as well.

description: Sustainable Development Goal 2 is hinged on achieving zero hunger, worldwide, by the year 2030. Many developing countries, especially African countries, are faced with extreme hunger often caused or compounded by bad governance, conflicts and climate change. In this paper, we review patterns of Global Hunger Index scores across Africa from 2000 to 2018 noting advances and setbacks in the fight against hunger in relation to the underlying causes of hunger in these nations, using Nigeria, the poverty capital of the world, as a case study. We also review selected policies of the Nigerian government and development partners aimed at reducing hunger in Nigeria and proffer solutions that can help actualise the target of zero hunger by 2030
Validity of Gauge-Fixing Conditions and the Structure of Propagators in Open Superstring Field Theory

description: We make a detailed analysis on validity of gauge-fixing conditions and the structure of propagators in the Wess-Zumino-Witten-type open superstring field theory. First, we generalize the gauge-fixing conditions considered in JHEP 03 (2012) 030 [arXiv:1201.1761] by the present author et al., and propose a large class of conditions characterized by zero modes of world-sheet oscillators. Then we demonstrate its validity: we prove that gauge degrees of freedom allow us to impose the conditions, and that the conditions fix the gauges completely. Moreover, we elucidate how the information about the gauge choices is reflected in the structure of propagators. The results can be readily extended to the case in which gauge-fixing conditions involve linear combinations of the world-sheet oscillators, including nonzero modes. We investigate also such extended gauges, which are the counterpart of linear $b$-gauges in bosonic string field theory, and obtain the corresponding propagators.

Labelled glossaries in the context of migration: a proposal for Italian and English
Creators: name: Longobardi, Ferdinando
name: Pastorino, Valeria
Publisher: name: De Europa
Year: 2023

description: This paper investigates the way in which the words used to talk about migration are described by international organisations and public administrations. It proposes a more detailed description of the words that takes into account the morphological characteristics of each word, starting from corpora drawn from the Italian version of the EMN Glossary on Asylum and Migration and the English version of the IOM Glossary on Migration. The study introduces original excerpts of morphologically labelled glossaries comprising of the most frequent words in the migration context. The labelled glossaries present the description of the word units and an explanation of their grammatical behaviours, using tools and techniques from the Lexicon-Grammar theory to account for words’ features usually considered as mere irregularities. The addition of these morphological labels to describe the behaviour of the words in the context of migration would allow them to be used with confidence by speakers, even those whose first language is not that of the country in which they find themselves, thus putting the individual at the core of the issue by giving those most effected the power to voice their opinions.

description: The response of matter to an optical excitation consists essentially of absorption and emission. Traditional spectroscopy accesses the frequency-resolved and time-integrated response, while the temporal evolution stays concealed. However, we will demonstrate here that the temporal evolution of a virtual single-photon transition can be mapped out by a second pulsed electromagnetic field. The resulting optical signal shows previously unexpected optical gain and loss, which can be gated and controlled via the relative delay of the electromagnetic fields. The model presented here can be applied to any system that assumes a two-level character through near-resonant optical dipole excitation, whether they are of atomic, molecular or even solid-state nature. These theoretical observations are in excellent qualitative agreement with our transient absorption spectroscopy study in helium. The presented results can act as starting point for a new scheme for creating optical gain, which is a prerequisite for the operation of lasers. It may be possible to open the doors to spectral regions, which were difficult to access until now, e.g. in the extreme ultraviolet.

description: We study variational regularization methods in a general framework, more precisely those methods that use a discrepancy and a regularization functional. While several sets of sufficient conditions are known to obtain a regularization method, we start with an investigation of the converse question: How could necessary conditions for a variational method to provide a regularization method look like? To this end, we formalize the notion of a variational scheme and start with comparison of three different instances of variational methods. Then we focus on the data space model and investigate the role and interplay of the topological structure, the convergence notion and the discrepancy functional. Especially, we deduce necessary conditions for the discrepancy functional to fulfill usual continuity assumptions. The results are applied to discrepancy functionals given by Bregman distances and especially to the Kullback-Leibler divergence.

description: We explore models in which weakly interacting massive particle (WIMP) dark matter annihilation is directly responsible for baryogenesis, thereby connecting dark matter with baryogenesis. We call this process "WIMPy baryogenesis". The dark matter relic density in these models, as with conventional WIMP models, is obtained with only order one couplings and TeV-scale masses according to the WIMP miracle. Thus, WIMPy baryogenesis models naturally accommodate weak-scale dark matter. Furthermore, an extension of the WIMP miracle simultaneously explains the observed baryon asymmetry and the correct dark matter abundance. The models we present have the further feature that they create the baryon number asymmetry at the weak scale, thereby avoiding the problems in some models of baryogenesis associated with high reheat temperatures in supersymmetric theories. Some of these models yield observable consequences in ongoing and future experiments.

Le multilinguisme, levier de légitimation pour la présidente de la Commission Européenne ? Représentation d’Ursula von der Leyen en figure d’autorité polyglotte
Creators: name: Charbonneaux, Juliette
Publisher: name: De Europa
Year: 2023

description: Depuis son arrivée à la tête de la Commission Européenne en 2019, Ursula von der Leyen s’est fait (re)connaître, notamment, par sa capacité à s’exprimer en plusieurs langues de l’Union. Ses différents « discours sur l’État de l’Union » ont ainsi été l’occasion pour elle de manifester son aisance dans sa langue maternelle, l’allemand, mais aussi en anglais ou en français, aisance qui n’a pas manqué d’être relevée et soulignée par les médias couvrant cet événement discursif et politique bien ritualisé. Partant de ce constat, cet article entend interroger le rôle légitimant, pour le politique, que peut endosser le multilinguisme dans le cas de la communication d’une institution bien spécifique, la Commission Européenne, et de la « figure d’autorité » (Wrona&Seignobos 2017) qui la dirige. Dans quelle mesure l’occupation du terrain politique européen passe-t-elle par une conquête sémiotique qui connote « l’hospitalité langagière » (Ricoeur 1992) ? En quoi cette hospitalité et la polyphonie qui l’accompagne permettent-elle alors à la figure et à l’institution qui la promeuvent de faire autorité en s’attirant la reconnaissance des médias ? Reprenant à notre compte la théorie de Louis Marin, nous postulons que l’autorité passe immanquablement par un travail de représentation sémiotique, lui-même condition de possibilité de la reconnaissance (Marin 1981).

English Language and Brexit: A Linguistic Analysis of the Legal Texts of the EU
Creators: name: Guarino, Ornella
Publisher: name: De Europa
Year: 2023

description: To this date, English is one of the working languages of the EU and, most importantly, it is the ‘de facto’ lingua franca of the EU, as the source language of most European documents is mainly English (Crystal 2017). Despite Brexit, English remains the most studied language in Europe (Kużelewska 2020), not to mention the fact that it is the language of globalization. However, the UK’s exit from the EU prompts the question as to what will be the development of English in the post-Brexit landscape. In light of this, the present article aims at conducting a linguistic analysis of Euro-English in order to assess if and how such type of English differs from the Standard English (SE). If yes, is it possible that the Brexit phenomenon will contribute even further to the consolidation of a new variety of English in its own terms? There is an ongoing debate on this issue, which is perhaps more topical today than ever before. The purpose of this article is therefore to analyze the current status of the English language used in EU legislation. In order to do so, this article provides a brief introduction of the linguistic landscape of the EU, by assessing the historical process of multilingualism and the EU egalitarian language policy. Subsequently, the article goes on to the analysis of a corpus of EU legislation (Directives, Regulations, Decisions, Recommendations, Opinions) drawn up in English in the last decades (1992-2022) to assess whether Euro-English has specific linguistic features at the lexical, morphosyntactic, and textual levels. The selected corpus of EU legal texts is compared to a corpus of UK legislation elaborated during the same time frame and the data are processed using the WordSmith Tools 8.0 software. Keywords: English Language; Euro-English; Brexit; Legal Discourse; Legislative Drafting.

Comment encadrer juridiquement la communication internet des institutions européennes en matière de multilinguisme ?
Creators: name: Clement -Wilz, Laure
Publisher: name: De Europa
Year: 2023

description: Les institutions de l’Union européenne ont depuis longtemps investi dans les politiques de communication (D’Ambrosi 2019) et apparaissent pionnières de la communication sur internet (Badouard et Malherbe 2015 : 33). Elles communiquent en ligne sur différents supports, comme les sites institutionnels et les réseaux sociaux. Si la politique de communication trouve un fondement juridiquei, son encadrement juridique en matière d’usage des langues est quasiment inexistant. Les règles juridiques qui s’appliquent en matière linguistique, issues du droit primaire (c’est-à-dire du traité sur l’Union européenne, du traité sur le fonctionnement de l’Union européenne et de la Charte des droits fondamentaux), du droit dérivé (c’est-à-dire le Règlement n°1/58, dit Règlement No 1, portant fixation du régime linguistique de la Communauté Économique Européenne et le Règlement n°31/62 fixant le statut des fonctionnaires et le régime applicable aux autres agents de la Communauté économique européenne et de la Communauté européenne de l'énergie atomique), et de la jurisprudence de la Cour de justice de l’Union européenne, préservant leur marge de manœuvre formelle en matière de communication sur internet.

Reclaiming the public through the establishment of a senate in a nascent university
Creators: name: McGillivray, Judith
Publisher: name: University of British Columbia
Year: 2013

description: This thesis is an attempt to respond to the governance challenges created by the establishment of five new "teaching-intensive" universities in British Columbia in 2008 with particular reference to Kwantlen Polytechnic University. Like each of the other new universities, Kwantlen had a substantial institutional history, in Kwantlen's case as a college, then university-college; becoming a university invoked new values, new traditions that were, ironically, anchored in centuries old conversations about what it means to be a university-and who made decisions about what. To reflect its new status, Kwantlen's governance structure was changed overnight from unicameral, centralized and hierarchical to one that aimed to be bicameral, devolved and egalitarian. As provost of Kwantlen Polytechnic University I can testify that the lived experience of the transition was not so swift. The clash of governance approaches provides an opportunity to consider the purpose of university governance-and of universities themselves.The history of Western and Islamic universities is one of struggle for intellectual independence, with concern for faculty primacy in academic decision-making and institutional autonomy from church and/or state, leading to a complex and symbiotic relationship between universities and democracy. To better understand the connection between the university as a democratic institution and bicameral governance, I turn to one of the most influential democratic theorists of the 20th century, Hannah Arendt, and her diagnosis and suggested remedies for current problems of democracy. Arendt argues that democracy depends on a robust public space where people can appear to one another and debate how they can live together-a space that has been "darkened" by the incursions of a social-bureaucratic space that creates "rule by nobody." Her remedy is the creation of new public spaces, which, ironically, depend on a parallel development of private spaces in which to prepare for the agonal public. I attempt to take advantage of Kwantlen's transition from college to university to "think what we are doing" (Arendt, 1958, p. 5) by appropriating Arendt's ideas to understand how a new university can govern itself more democratically.

Multilinguisme et Union européenne : Introduction
Creators: name: Hermand, Marie-Hélène
name: Niessen, Annie
Publisher: name: De Europa
Year: 2023

description: Les diverses langues présentes au sein des États membres de l’Union européenne (UE) constituent probablement l’une des expressions les plus directes de sa devise “Unie dans la diversité”. La politique linguistique de l’Union européenne repose sur le respect de cette diversité, notamment au travers de la reconnaissance de 24 langues officielles. Cette ouverture au multilinguisme entretenue par l’UE amène à s’intéresser aux contextes, aux dispositifs et aux usages linguistiques élaborés par l’UE pour s’adresser à ses citoyens, à ses partenaires politiques et économiques, aux populations fragiles (en difficulté économique ou migrantes) ou encore aux médias.

description: We report the experimental verification of metamaterial cloaking for a 3D object in free space. We apply the plasmonic cloaking technique, based on scattering cancellation, to suppress microwave scattering from a finite-length dielectric cylinder. We verify that scattering suppression is obtained all around the object in the near- and far-field and for different incidence angles, validating our measurements with analytical results and full-wave simulations. Our near-field and far-field measurements confirm that realistic and robust plasmonic metamaterial cloaks may be realized for elongated 3D objects with moderate transverse cross-section at microwave frequencies.

On functors preserving skeletal maps and skeletally generated compacta

description: A map $f:X\to Y$ between topological spaces is skeletal if the preimage $f^{-1}(A)$ of each nowhere dense subset $A\subset Y$ is nowhere dense in $X$. We prove that a normal functor $F:Comp\to Comp$ is skeletal (which means that $F$ preserves skeletal epimorphisms) if and only if for any open surjective open map $f:X\to Y$ between zero-dimensional compacta with two-element non-degeneracy set $N^f=\{x\in X:|f^{-1}(f(x))|>1\}$ the map $Ff:FX\to FY$ is skeletal. This characterization implies that each open normal functor is skeletal. The converse is not true even for normal functors of finite degree. The other main result of the paper says that each normal functor $F: Comp\to Comp$ preserves the class of skeletally generated compacta. This contrasts with the known Shchepin's result saying that a normal functor is open if and only if it preserves openly generated compacta.

description: Creation of the guideline was driven by a use case involving a collaborative agreement with the United States (U.S.) Social Security Administration (SSA) to leverage clinical natural language processing to improve the disability determination process.  The research purpose was to develop tools that automate the detection of relevant functional information in electronic health records (EHR) to support medical record review by adjudicators. This guideline aims to standardize self-care and domestic life information documented in free-text EHRs and provide a process for annotating this information. These efforts resulted in the creation of a gold standard corpus, which has been used to develop computational models of functioning.   

Contents of the guideline include an (1) Introduction that recommends how the guideline should be used, a description of the ICF as the conceptual framework, and an explanation of how self-care and domestic life functioning is conceptualized; (2) Annotation data description; (3) Annotation tool description; (4) Annotation schema, including the entity, attribute, and value definitions, ICF codes and SNOMED clinical terms codes used, and their definitions and operationalization with examples of annotated text; (5) General annotation considerations; (6) Domain specific considerations; (7) Edge or difficult cases; (8) Acknowledgements; (9) References, and (10) four Appendices including an example of an annotated  note and a troubleshooting guide. 

This guideline was developed by clinical rehabilitation domain experts with backgrounds in occupational therapy, physical therapy, and primary care medicine, and individuals with public health and data science expertise.  The International Classification of Functioning, Disability, and Health (ICF) is used as a framework for this work and aims to develop analytic tools for clinical natural language processing and vocabularies of function. 
description: Version 1.1 of the Self-Care & Domestic Life (SCDL) annotation guideline includes minor changes to the annotation schema to standarize nomenclature (all labels are now lowercase, use underscores to replace spaces, and change "type" to "source"). These changes have been updated in all text, tables, and figures within the guideline. This version also includes a revised Figure 6 and updates to two examples to correct the assigned Action polarity.

description: Objective: To determine the motor phenotype of LRRK2 G2019S mutation carriers. LRRK2 mutation carriers were previously reported to manifest the tremor dominant motor phenotype, which has been associated with slower motor progression and less cognitive impairment compared with the postural instability and gait difficulty (PIGD) phenotype. Design: Cross-sectional observational study. Setting: Thirteen movement disorders centers. Participants: Nine hundred twenty-five early-onset Parkinson disease cases defined as age at onset younger than 51 years. Main Outcome Measures: LRRK2 mutation status and Parkinson disease motor phenotype: tremor dominant or PIGD. Demographic information, family history of Parkinson disease, and the Unified Parkinson's Disease Rating Scale score were collected on all participants. DNA samples were genotyped for LRRK2 mutations (G2019S, I2020T, R1441C, and Y1699C). Logistic regression was used to examine associations of G2019S mutation status with motor phenotype adjusting for disease duration, Ashkenazi Jewish ancestry, levodopa dose, and family history of Parkinson disease. Results: Thirty-four cases (3.7%) (14 previously reported) were G2019S carriers. No other mutations were found. Carriers were more likely to be Ashkenazi Jewish (55.9% vs 11.9%; P < .001) but did not significantly differ in any other demographic or disease characteristics. Carriers had a lower tremor score (P = .03) and were more likely to have a PIGD phenotype (92.3% vs 58.9%; P = .003). The association of the G2019S mutation with PIGD phenotype remained after controlling for disease duration and Ashkenazi Jewish ancestry (odds ratio, 17.7; P < .001). Conclusion: Early-onset Parkinson disease G2019S LRRK2 carriers are more likely to manifest the PIGD phenotype, which may have implications for disease course.
