Abstract:
Interpretations of women's activism depend on the ways in which analysts conceptualize the relations between privacy, publicity, and politics, in this paper the relationship between women's standing in the public sphere and their activism is problematized. Women's activism is shaped by strategic, and sometimes opportunistic, choices to locate their activism either in public or in private spaces. These choices point to the importance of reconceptualizing publicity and privacy in ways that separate the content of actions from the spaces in which action is taken. Such a distinction creates the possibility of taking private actions into public spaces and of taking public actions in private spaces. When the content of action is separated from the spaces of action, women's activism is evaluated in terms of the efficacy of various actions in either public or private spaces, rather than in terms of women's presumed lack of access to the public sphere.

Abstract:
We address the following natural extension problem for group actions: Given a group [Formula: see text], a subgroup [Formula: see text], and an action of [Formula: see text] on a metric space, when is it possible to extend it to an action of the whole group [Formula: see text] on a (possibly different) metric space? When does such an extension preserve interesting properties of the original action of [Formula: see text]? We begin by formalizing this problem and present a construction of an induced action which behaves well when [Formula: see text] is hyperbolically embedded in [Formula: see text]. Moreover, we show that induced actions can be used to characterize hyperbolically embedded subgroups. We also obtain some results for elementary amenable groups.

Abstract:
<p>A Cauchy group (G,D,·) has a Cauchy-action on a filter space (X,C), if it acts in a compatible manner. A new filter-based method is proposed in this paper for the notion of group-action, from which the properties of this action such as transitiveness and its compatibility with various modifications of the G-space (X,C) are determined. There is a close link between the Cauchy action and the induced continuous action on the underlying G-space, which is explored here. In addition, a possible extension of a Cauchy-action to the completion of the underlying G-space is discussed. These new results confirm and generalize some of the properties of group action in a topological context.</p>

Abstract:
This article examines several key sites where Russia’s civic and religious bodies intersect in pursuit of social justice goals. Based on ethnographic fieldwork among religious communities and social justice organizations in Moscow, the article focuses on the physical, social, and legal spaces where church and state, secular and sacred, civic and personal intersect and the consequences of these intersections for how Russians understand new configurations of church and state, private and public, religious and political. Of particular concern is the emergence of new forms of religious and political pluralism that transcend any one particular space, such as for worship, community life, or political support or protest, and instead reveal shifting practices and ethics of social justice that are more pluralist, progressive, and tolerant than they may appear to be to outside observers.

Abstract:
Monte-Carlo Tree Search (MCTS) is the state-of-the-art online planning algorithm for large problems with discrete action spaces. However, many real-world problems involve continuous action spaces, where MCTS is not as effective as in discrete action spaces. This is mainly due to common practices such as coarse discretization of the entire action space and failure to exploit local smoothness. In this paper, we introduce Value-Gradient UCT (VG-UCT), which combines traditional MCTS with gradient-based optimization of action particles. VG-UCT simultaneously performs a global search via UCT with respect to the finitely sampled set of actions and performs a local improvement via action value gradients. In the experiments, we demonstrate that our approach outperforms existing MCTS methods and other strong baseline algorithms for continuous action spaces.

Abstract:
Any compact, connected Lie group which acts effectively on a closed aspherical manifold is a torus Tk with k ≤ rank of [Formula: see text], the center of π1 (M). When [Formula: see text], the torus action is called a maximal torus action. The authors have previously shown that many closed aspherical manifolds admit maximal torus actions. In this paper, a smooth maximal torus action is constructed on each solvmanifold. They also construct smooth maximal torus actions on some double coset spaces of general Lie groups as applications.

We show that a continuous action of a quantum semigroup [Formula: see text] on a finite quantum space (finite dimensional C*-algebra) preserving a faithful state comes from a continuous action of the quantum Bohr compactification [Formula: see text] of [Formula: see text]. Using the classification of continuous compact quantum group actions on M2, we give a complete description of all continuous quantum semigroup actions on this quantum space preserving a faithful state.

This thesis presents a new approach for a Navy unmanned undersea vehicle (UUV) to search for and detect an evading contact. This approach uses a contact position distribution from a generic particle filter to estimate the state of a single moving contact and to plan the path that minimizes the uncertainty in the location of the contact. The search algorithms introduced in this thesis will implement a motion planner that searches for a contact with the following information available to the decision system: (1) null measurement (i.e., contact not detected at current time), (2) timedated measurement (i.e., clue found at current time that indicates contact was at this location in the past), and (3) bearings measurement (i.e., angular measurement towards contact position detected at current time). The results of this thesis will be arrived at by evaluating the best methods to utilize the three types of information. The underlying distribution of the contact state space will be modeled using a generic particle filter, due to the highly non-Gaussian distributions that result from the conditions mentioned above. Using the particle filter distribution and the measurements acquired from the three conditions, this thesis will work towards implementing a path planning algorithm that creates dynamic action spaces that evaluate the uncertainty of position distribution. Ultimately, the path planner will choose the path that contains the position distribution and leads to sustained searches.

Abstract:
Thesis (Ph.D.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 1999.
Includes bibliographical references (p. 246-258).
This thesis presents new theory and technology for the representation and recognition of complex, context-sensitive human actions in interactive spaces. To represent action and interaction a symbolic framework has been developed based on Roger Schank's conceptualizations, augmented by a mechanism to represent the temporal structure of the sub-actions based on Allen's interval algebra networks. To overcome the exponential nature of temporal constraint propagation in such networks, we have developed the PNF propagation algorithm based on the projection of IA-networks into simplified, 3-valued (past, now, future) constraint networks called PNF-networks. The PNF propagation algorithm has been applied to an action recognition vision system that handles actions composed of multiple, parallel threads of sub-actions, in situations that can not be efficiently dealt by the commonly used temporal representation schemes such as finite-state machines and HMMs. The PNF propagation algorithm is also the basis of interval scripts, a scripting paradigm for interactive systems that represents interaction as a set of temporal constraints between the individual components of the interaction. Unlike previously proposed non-procedural scripting methods, we use a strong temporal representation (allowing, for example, mutually exclusive actions) and perform control by propagating the temporal constraints in real-time. These concepts have been tested in the context of four projects involving story-driven interactive spaces. The action representation framework has been used in the Intelligent Studio project to enhance the control of automatic cameras in a TV studio. Interval scripts have been extensively employed in the development of "SingSong ", a short interactive performance that introduced the idea of live interaction with computer graphics characters; in "It/I", a full-length computer theater play; and in "It", an interactive art installation based on the play "It /I" that realizes our concept of immersive stages, that is, interactive spaces that can be used both by performers and public.

Abstract:
Given a convergence space X, a continuous action of a convergence semigroup S on X and a compactification Y of X, under what conditions on X and the action on X is it possible to extend the action to a continuous action on Y. Similarly, given a Cauchy space X, a Cauchy continuous action of a Cauchy semigroup S on X and a completion Y of X, under what conditions on X and the action on X is it possible to extend the action to a Cauchy continuous action on Y. We answer the first question for some particular compactifications like the one-point compactification and the star compactification as well as for the class of regular compactifications. We answer the second question for the class of regular strict completions. Using these results, we give sufficient conditions under which the pseudoquotient of a compactification/completion of a space is the compactification/completion of the pseudoquotient of the given space.

The public role of effectively guiding, evaluating and prescribing the physical places, patterns and forms we produce and live in according to commonly held external socio-political ideals has been extremely constrained by our limited knowledge of the significance and consequences of the physical environments we produce and live in, and by incomplete social and planning theories that isolate intentions from actions, processes from ideals, individuals from institutions, and space from society . Central to all of these limits of knowledge and fragments of theory is an inadequately developed theory of human act, acting, and action in space and time. We are unable to identify the significant patterns of human activity , in their forms and consequences, and we are unable to do so in an easily understandable way. Action is confused with acts and acting. For there to be an effective, significant and qualitative public debate we must first extend our knowledge of the significance and consequences of the environments we produce and live in, to include a theory of human action in these environments. Only after this theory has been developed can we effectively debate the forms that we produce according to commonly held socio-political ideals. Justice can exist in environments, and environments do contribute to justice. They can and do if we understand environments as structures of human action in time and space, and if we understand justice as a complex ideal consisting of aspects of equality, liberty, opportunity, participation, and difference.

Abstract:
This research involves understanding the civic learning that emerged from the ways individuals in two civic action groups, Greenhill Historical Society (GHS) in Bonnybridge, a deindustrialised location, and Cumbernauld Village Action for the Community (CVAC) in Cumbernauld Village, a Conservation Area, enacted their citizenship through the spatial (geographical) and temporal (historical) characteristics of their place. I use a citizenship-as-practice conceptualisation, where citizenship is not a status ‘given’ to individuals who have successfully displayed pre-requisite outcomes, but is a continuous and indeterminate practice through exposure to real challenges. To understand the learning occurring for, from and through their practices, I used Biesta’s theory of civic learning (Biesta, 2011). It involves a socialisation conception of civic learning as the adoption of existing civic identities, where individuals adapt to a given political order, and a subjectification conception which focuses on how political agency is achieved. The theory connects learning and action together, where Biesta argues socialisation involves the individual requiring to learn something in order to carry out the ‘correct’ actions in the future; however, subjectification involves action preceding learning, where learning comes second, if at all. I used a case study design and a psychogeographic mapping methodology involving secondary data analysis, psychogeographic mapping interviews and observations. Civic action emerged as a more central component than civic learning through my empirical analysis. The civic actions of GHS emerged as a case of reconsideration (redefining, re-meaning their location through interventions in public), and CVAC of reconfiguration (actions physically altering the landscape). These actions concerning space and time involved spatial shifts from mapreading to mapmaking, and temporal shifts from histories ‘of’ and ‘for’ the public, towards histories ‘by’ the public. Respondents became ‘curators’ of their places: from spectators to participants in making and representing spaces and histories that opened their locations to interruptions of the continuities of time. Attending to practices of citizens with space and time contains possibilities for public pedagogies that work ‘with’ context rather than just ‘in’, towards opening up opportunities for citizens to ‘become public’ as practices that trouble pre-existing arrangements and configurations.

Abstract:
The potential of communities for sustainability learning and governance has generated substantial interest in sustainability discourses, but their specific roles and remits are not always critically examined. This thesis' original contribution to these discourses lies in the analysis of community projects as liminal spaces for pro-sustainable change that are limited in scope within wider political landscapes that do not sufficiently address wider challenges of an unravelling biosphere. The particular manifestation of community projects which emerges in Scotland as a result of Climate Challenge Fund funding made available by the Scottish Government is one example of sustainability governance at a local level. The present study draws upon data from field notes of eleven months of fieldwork, and semi-structured interviews with fifty-two informants, constructing two case studies with references to a third one. A transdisciplinary analysis of findings examines leadership and organisational structures and their implication for governance, and similarities and differences in practices and values identified within the case studies. Community projects are described as liminal spaces which facilitate the learning, practice-based and theoretical knowledge of sustainable practices (such as food growing or energy efficiency), and stimulate thinking on behalf of the group of participants or wider community. Community projects may also build temporary spaces demonstrating sustainable solutions visible to passers-by (such as raised vegetable beds in community gardens, or second-hand clothing in a swap shop). However, the longevity of these solutions is uncertain once the grant funding has come to an end. It is argued that in wider Scottish society, high-carbon lifestyles, inequalities and economic growth are the norm, and sustainable practices, community sustainability governance of tangible assets, and Education for Sustainable Development need to become less marginal and more widely embedded across all social and economic institutions.

Full text
Abstract:
This thesis is about the dynamic generalisation of continuous action spaces in reinforcement learning problems. The standard Reinforcement Learning (RL) account provides a principled and comprehensive means of optimising a scalar reward signal in a Markov Decision Process. However, the theory itself does not directly address the imperative issue of generalisation which naturally arises as a consequence of large or continuous state and action spaces. A current thrust of research is aimed at fusing the generalisation capabilities of supervised (and unsupervised) learning techniques with the RL theory. An example par excellence is Tesauro’s TD-Gammon. Although much effort has gone into researching ways to represent and generalise over the input space, much less attention has been paid to the action space. This thesis first considers the motivation for learning real-valued actions, and then proposes a set of key properties desirable in any candidate algorithm addressing generalisation of both input and action spaces. These properties include: Provision of adaptive and online generalisation, adherence to the standard theory with a central focus on estimating expected reward, provision for real-valued states and actions, and full support for a real-valued discounted reward signal. Of particular interest are issues pertaining to robustness in non-stationary environments, scalability, and efficiency for real-time learning in applications such as robotics. Since exploring the action space is discovered to be a potentially costly process, the system should also be flexible enough to enable maximum reuse of learned actions. A new approach is proposed which succeeds for the first time in addressing all of the key issues identified. The algorithm, which is based on the ubiquitous self-organising map, is analysed and compared with other techniques including those based on the backpropagation algorithm. The investigation uncovers some important implications of the differences between these two particular approaches with respect to RL. In particular, the distributed representation of the multi-layer perceptron is judged to be something of a double-edged sword offering more sophisticated and more scalable generalising power, but potentially causing problems in dynamic or non-equiprobable environments, and tasks involving a highly varying input-output mapping. The thesis concludes that the self-organising map can be used in conjunction with current RL theory to provide real-time dynamic representation and generalisation of continuous action spaces. The proposed model is shown to be reliable in non-stationary, unpredictable and noisy environments and judged to be unique in addressing and satisfying a number of desirable properties identified as important to a large class of RL problems.

Abstract:
In this paper we propose a hybrid architecture of actor-critic algorithms for reinforcement learning in parameterized action space, which consists of multiple parallel sub-actor networks to decompose the structured action space into simpler action spaces along with a critic network to guide the training of all sub-actor networks. While this paper is mainly focused on parameterized action space, the proposed architecture, which we call hybrid actor-critic, can be extended for more general action spaces which has a hierarchical structure. We present an instance of the hybrid actor-critic architecture based on proximal policy optimization (PPO), which we refer to as hybrid proximal policy optimization (H-PPO). Our experiments test H-PPO on a collection of tasks with parameterized action space, where H-PPO demonstrates superior performance over previous methods of parameterized action reinforcement learning.

Abstract:
Users' behaviors observed in many web-based applications are usually heterogeneous, so modeling their behaviors considering the interplay among multiple types of actions is important. However, recent collaborative filtering (CF) methods based on a metric learning approach cannot learn multiple types of user actions, because they are developed for only a single type of user actions. This paper proposes a novel metric learning method, called METAS, to jointly model heterogeneous user behaviors. Specifically, it learns two distinct spaces: 1) action space which captures the relations among all observed and unobserved actions, and 2) entity space which captures high-level similarities among users and among items. Each action vector in the action space is computed using a non-linear function and its corresponding entity vectors in the entity space. In addition, METAS adopts an efficient triplet mining algorithm to effectively speed up the convergence of metric learning. Experimental results show that METAS outperforms the state-of-the-art methods in predicting users' heterogeneous actions, and its entity space represents the user-user and item-item similarities more clearly than the space trained by the other methods.

Abstract:
This paper reports on the experience gained with an undergraduate Law module – LW3372 Environmental Law: Contemporary Issues in Governance, Regulation and Enforcement – in the academic year 2018/19. This module incorporates specific features designed to enable students to engage with environmental law ‘in action’ through experiential learning opportunities set in the context of a research-based approach to teaching and learning. In 2018/19, the module was restructured to map it on to the Connected Curriculum framework adopted by University College Cork (University College Cork, 2018). This involved, in particular, a stronger focus on the research component which forms part of the assessment for the module and more explicit linkages to law ‘in action’, specifically: how to engage Law to solve contemporary societal challenges. The module also sought to draw out and engage with implementation of the Sustainable Development Goals (SDGs) with a particular focus on Goal 13 Climate Action and Goal 16 Peace, Justice and Strong Institutions (UN General Assembly, 2015). The research objective underpinning this project was to explore and report on the experience of implementing selected elements of University College Cork’s Connected Curriculum framework in an undergraduate module. The project on which this paper is based drew on the detailed framework for curriculum design and renewal developed by Dilly Fung at University College London (UCL) (Fung, 2017). The core principle underpinning UCL’s Connected Curriculum initiative is that students learn through research and active enquiry. One particularly important dimension of the model developed by Fung involves connecting students with research and researchers. Early exposure to frontier research, together with the opportunity to connect directly with researchers and practitioners who are working to solve societal challenges, equips students with invaluable insights into their field of study. It also serves to demonstrate to students the fundamental role of research in society. Connecting effectively with research facilitates a further dimension of the Connected Curriculum framework – ‘outwardfacing student assessments’. In other words, the assessment element of a module or programme, as the case may be, is conceptualised and designed to be the ‘output’ of a student’s own research and enquiry. Depending on the particular model of assessment deployed, this ‘output’ may have an impact on local and wider audiences (e.g. policy briefs, research reports, blogs, podcasts, student-run events etc.). This outward-facing focus, and the emphasis on student-generated outputs, is a key element of delivering impactful experiential learning opportunities in the field of environmental law.

Abstract:
This Emerging Evidence Report shares evidence of how, for whom, and under what circumstances, Participatory Action Research (PAR) leads to innovative actions. A rapid realist review was undertaken to develop programme theories that explain how PAR generates innovation. The methodology included peer-reviewed and grey literature and moments of engagement with programme staff, such that their input supported the development and refinement of three resulting initial programme theories (IPTs) that we present in this report. Across all three IPTs, safe relational space, group facilitation, and the abilities of facilitators, are essential context and intervention components through which PAR can generate innovation. Implications from the three IPTs for evaluation design of the CLARISSA programme are identified and discussed. The report finishes with opportunities for the CLARISSA programme to start building an evidence base of how PAR works as an intervention modality, such as evidencing group-level conscientisation, the influence of intersecting inequalities, and influence of diverse perspectives coming together in a PAR process.
