Traces of functions in Fock spaces on lattices of critical density

Following a scheme of Levin we describe the values that functions in Fock spaces take on lattices of critical density in terms of both the size of the values and a cancelation condition that involves discrete versions of the Cauchy and Beurling-Ahlfors transforms.

Hardy���s inequalities for monotone functions on partly ordered measure spaces

We characterize the weighted Hardy inequalities for monotone functions in Rn +. In dimension n = 1, this recovers the standard theory of Bp weights. For n > 1, the result was previously only known for the case p = 1. In fact, our main theorem is proved in the more general setting of partly ordered measure spaces.

Parking for Person With Disabilities, June 16, 2010

Persons with disabilities may find it challenging to fully use and enjoy their dwelling without adequate accessible parking. The State of Iowa has specific laws and regulations regarding accessible parking for persons with disabilities. Iowa Code Chapter 321L (1990); 661Iowa Admin. Code Chapter 18 (321L) (2010). In addition, there are state and federal fair housing laws that prohibit discrimination in parking for persons with disabilities ��� the federal ���Fair Housing Act,��� the ���Americans with Disabilities Act��� (ADA), and the ���Iowa Civil Rights Act of 1965.��� 42 U.S.C. ���� 3600- 3620; 42 U.S.C. �� 12101; and Iowa Code Chapter 216. It may at times be challenging for a housing provider to fully understand and correctly apply all of these laws to their particular off-street parking situations and needs; however, by reviewing these laws and answering certain key questions, this paper will assist providers in achieving greater understanding and help insure greater compliance with these laws.

Commercial Vehicle Parking, 1999

The purpose of the study was to review Iowa's public policy issues related to the state provision of overnight commercial truck parking and to make recommendations regarding the same. It was decided to limit the research and data gathering to a study of national trends in public commercial truck parking at facilities along and adjacent to Iowa's interstate highways.

The normal distribution in some constrained sample spaces

Phenomena with a constrained sample space appear frequently in practice. This is the case e.g. with strictly positive data, or with compositional data, like percentages or proportions. If the natural measure of difference is not the absolute one, simple algebraic properties show that it is more convenient to work with a geometry different from the usual Euclidean geometry in real space, and with a measure different from the usual Lebesgue measure, leading to alternative models which better fit the phenomenon under study. The general approach is presented and illustrated using the normal distribution, both on the positive real line and on the D-part simplex. The original ideas of McAlister in his introduction to the lognormal distribution in 1879, are recovered and updated

Bayes linear spaces

Linear spaces consisting of ��-���nite probability measures and in���nite measures (improper priors and likelihood functions) are de���ned. The commutative group operation, called perturbation, is the updating given by Bayes theorem; the inverse operation is the Radon-Nikodym derivative. Bayes spaces of measures are sets of classes of proportional measures. In this framework, basic notions of mathematical statistics get a simple algebraic interpretation. For example, exponential families appear as af���ne subspaces with their suf���cient statistics as a basis. Bayesian statistics, in particular some well-known properties of conjugated priors and likelihood functions, are revisited and slightly extended

How diverse is Cologne Carnival? How migrants appropriate popular art spaces

The present article contributes to the ongoing academic debate on migrants' appropriation of artistic and political spaces in Germany. Cologne, one of the largest cities in Germany, is an interesting example of the tension between political discourse centred around multiculturalism and cultural segregation processes. The 'no fool is illegal' carnival organised by asylum seekers shows their capacity to act, as they reinvent an old local tradition by reinterpreting medieval rituals. Today, different groups and associations appropriate this festive art space: migrants, gays and lesbians, feminists and far-left groups either organise their own parties or take part in the official parties and parades as separate groups. As a result, the celebration of diversity figures on the local political agenda and becomes part of the official carnival festivities. This leads to a blurring of boundaries, whereby mainstream popular culture becomes more and more influenced by multicultural elements.

Invisible Environments: Old Age and its spaces

Despite the progressive ageing of a worldwide population, negative attitudes towards old age have proliferated thanks to cultural constructs and myths that, for decades, have presented old age as a synonym of decay, deterioration and loss. Moreover, even though every human being knows he/she will age and that ageing is a process that cannot be stopped, it always seems distant, far off in the future and, therefore, remains invisible. In this paper, I aim to analyse the invisibility of old age and its spaces through two contemporary novels and their ageing females protagonists ���Maudie Fowler in Doris Lessing ���s The Diary of a Good Neighbour and Erica March in Rose Tremain ���s The Cupboard. Although invisible to the rest of society, these elderly characters succeed in becoming significant in the lives of younger protagonists who, immersed in their active lives, become aware of the need to enlarge our vision of old age.

Better-quasi-order : ideals and spaces

This thesis deals with combinatorics, order theory and descriptive set theory. The first contribution is to the theory of well-quasi-orders (wqo) and better-quasi-orders (bqo). The main result is the proof of a conjecture made by Maurice Pouzet in 1978 his th��se d'��tat which states that any wqo whose ideal completion remainder is bqo is actually bqo. Our proof relies on new results with both a combinatorial and a topological flavour concerning maps from a front into a compact metric space. The second contribution is of a more applied nature and deals with topological spaces. We define a quasi-order on the subsets of every second countable To topological space in a way that generalises the Wadge quasi-order on the Baire space, while extending its nice properties to virtually all these topological spaces. The Wadge quasi-order of reducibility by continuous functions is wqo on Borei subsets of the Baire space, this quasi-order is however far less satisfactory for other important topological spaces such as the real line, as Hertling, Ikegami and Schlicht notably observed. Some authors have therefore studied reducibility with respect to some classes of discontinuous functions to remedy this situation. We propose instead to keep continuity but to weaken the notion of function to that of relation. Using the notion of admissible representation studied in Type-2 theory of effectivity, we define the quasi-order of reducibility by relatively continuous relations. We show that this quasi-order both refines the classical hierarchies of complexity and is wqo on the Borei subsets of virtually every second countable To space - including every (quasi-)Polish space. -- Cette th��se se situe dans les domaines de la combinatoire, de la th��orie des ordres et de la th��orie descriptive. La premi��re contribution concerne la th��orie des bons quasi-ordres (wqo) et des meilleurs quasi-ordres (bqo). Le r��sultat principal est la preuve d'une conjecture, ��nonc��e par Pouzet en 1978 dans sa th��se d'��tat, qui ��tablit que tout wqo dont l'ensemble des id��aux non principaux ordonn��s par inclusion forme un bqo est alors lui-m��me un bqo. La preuve repose sur de nouveaux r��sultats, qui allient la combinatoire et la topologie, au sujet des fonctions d'un front vers un espace m��trique compact. La seconde contribution de cette th��se traite de la complexit�� topologique dans le cadre des espaces To �� base d��nombrable. Dans le cas de l'espace de Baire, le quasi-ordre de Wadge est un wqo sur les sous-ensembles Bor��liens qui a suscit�� ��norm��ment d'int��r��t. Cependant cette relation de r��duction par fonctions continues s'av��re bien moins satisfaisante pour d'autres espaces d'importance tels que la droite r��elle, comme l'ont fait notamment remarquer Hertling, Schlicht et Ikegami. Nous proposons de conserver la continuit�� et d'affaiblir la notion de fonction pour celle de relation. Pour ce faire, nous utilisons la notion de repr��sentation admissible ��tudi��e en �� Type-2 theory of effectivity �� initi��e par Weihrauch. Nous introduisons alors le quasi-ordre de r��duction par relations relativement continues et montrons que celui-ci �� la fois raffine les hi��rarchies classiques de complexit�� topologique et forme un wqo sur les sous-ensembles Bor��liens de chaque espace quasi-Polonais.

Use and perception of urban green spaces in Barcelona

Background: Although the mechanisms are not well understood yet, evidence exists of the benefits of urban green spaces for human health. As a consequence, one of the concerns of public health interventions must be to promote the use of urban green spaces within cities. Aims: This study aims to explore the citizens��� purposes of use of urban green spaces as well as the elements related to the characteristics of these places that condition their use. Methods: In-depth interviews were conducted with non-hospitalised people living in different areas of Barcelona, with different socioeconomic status and different residential distance to urban green spaces (n = 20). Thematic content analysis of the qualitative data was performed. Results: Physical pursuits and attention restoration were identified as prominent purposes of use of urban green spaces. The natural features of urban green spaces were identified as the most relevant determiners for the use of these places. Conclusions: To promote the use of urban green spaces, qualitative findings from this study suggest that purpose-built places should be provided. Moreover, natural features of urban green spaces must be particularly taken into account when designing and maintaining them.

The Emergence of Regional ICT Regulatory Spaces

This paper examines the role that existing Latin American policy institutions and regulatory coordination mechanisms (otherwise referred to as ���regional regulatory spaces���) play in innovation and development of the ICT sector. In doing so, it recognizes that sector regulation does not currently match regional development, thereby limiting its potential progress. In order to shed light on the role that the ���regional regulatory space��� could potentially play, the author addresses three main questions: �� Is there a hierarchy of policies by which it is presumed easy to ���coordinate within well-defined technical subjects��� but extremely challenging to ���agree in matters of public policy?��� �� What would happen if policy divergence became more important than convergence? Is it reasonable to consider creating ���regional regulatory spaces?��� or should we focus solely on technological coordination? �� Do institutions capable of serving as effective regional regulatory spaces already exist in Latin America or should we consider modifying existing institutions or creating new institutions? After analyzing these three overarching areas of concern, this paper then discusses the need to create a regional space in order to harmonize ICT regulatory frameworks and public policies. Ultimately, this work aims to advance the institutional formulation beyond pre-existing efforts.

Mediating the Immediate ��� Endogenous meanings and simulated narratives in ludic spaces

The thesis discusses games and the gaming experience. It is divided into two main sections; the first examines games in general, while the second concentrates exclusively on electronic games. The text approaches games from two distinct directions by looking at both their spatiality and their narrativity at the same time. These two points of view are combined right from the beginning of the text as they are used in conceptualising the nature of the gaming experience. The purpose of the thesis is to investigate two closely related issues concerning both the field of game studies and the nature of games. In regard to studying games, the focus is placed on the juxtaposition of ludology and narratology, which acts as a framework for looking at gaming. In addition to aiming to find out whether or not it is possible to undermine the said state of affairs through the spatiality of games, the text looks at the interrelationships of games and their spaces as well as the role of narratives in those spaces. The thesis is characterised by discussing alternative points of view and its hypothetical nature. During the text, it becomes apparent that the relationship between games and narratives is strongly twofold: on one hand, the player continuously narrativizes the states the game is in while playing, while the narratives residing within the game space form their own partially separate narrative spaces, on the other. These spaces affect the conception the player has of the game states and the events taking place in the game space itself.
