For a wide range of people with limited upper- and lower-body mobility, interaction with robots remains a challenging problem. Due to various health conditions, they are often unable to use standard joystick interface, most of wheelchairs are equipped with. To accommodate this audience, a number of alternative human-machine interfaces have been designed, such as single switch, sip-and-puff, brain-computer interfaces. They are known as low throughput interfaces referring to the amount of information that an operator can pass into the machine. Using them to control a wheelchair poses a number of challenges. This thesis makes several contributions towards the design of robotic wheelchairs controlled via low throughput human-machine interfaces: (1) To improve wheelchair motion control, an adaptive controller with online parameter estimation is developed for a differentially driven wheelchair. (2) Steering control scheme is designed that provides a unified framework integrating different types of low throughput human-machine interfaces with an obstacle avoidance mechanism. (3) A novel approach to the design of control systems with low throughput human-machine interfaces has been proposed. Based on the approach, position control scheme for a holonomic robot that aims to probabilistically minimize time to destination is developed and tested in simulation. The scheme is adopted for a real differentially driven wheelchair. In contrast to other methods, the proposed scheme allows to use prior information about the user habits, but does not restrict navigation to a set of pre-defined points, and parallelizes the inference and motion reducing the navigation time. (4) To enable the real time operation of the position control, a high-performance algorithm for single-source any-angle path planning on a grid has been developed. By abandoning the graph model and introducing discrete geometric primitives to represent the propagating wave front, we were able to design a planning algorithm that uses only integer addition and bit shifting. Experiments revealed a significant performance advantage. Several modifications, including optimal and multithreaded implementations, are also presented.

Any unexpected disruption to WDM (Wavelength Division Multiplexing) based optical networks which carry data traffic at tera-bit per second may result in a huge loss to its end-users and the carrier itself. Thus survivability has been well-recognized as one of the most important objectives in the design of optical Internet. This thesis proposes a novel survivable routing architecture for the optical Internet. We focus on a number of key issues that are essential to achieve the desired service scenarios, including the tasks of (a) minimizing the total number of wavelengths used for establishing working and protection paths in WDM networks; (b) minimizing the number of affected working paths in case of a link failure; (c) handling large scale WDM mesh networks; and (d) supporting both Quality of Service (QoS) and best-effort based working lightpaths. To implement the above objectives, a novel path based shared protection framework namely Group Shared protection (GSP) is proposed where the traffic matrix can be divided into multiple protection groups (PGs) based on specific grouping policy, and optimization is performed on these PGs. To the best of our knowledge this is the first work done in the area of group based WDM survivable routing approaches where not only the resource sharing is conducted among the PGs to achieve the best possible capacity efficiency, but also an integrated survivable routing framework is provided by incorporating the above objectives. Simulation results show the effectiveness of the proposed schemes.

This study was designed to assess the types of shared service arrangements and the degree of commitment as evidenced by the incorporation of policy statements displayed toward the sharing concept evident in the Dallas-Fort Worth hospitals. The purpose of this research, then, was to identify and evaluate present utilization of shared arrangements to establish a base for comparison and recommendations for future participation by the various categories of hospitals. The conclusions derived from the findings include the following: 1. Shared services promise to be a continuing factor in the operation of the health care industry in the future. 2. Governmental influence and regulation will expand into every area of health care. Hospital administrators must take every opportunity to contribute input to the formulation of these regulations. 3. The selection of products or services to be shared must be handled in a systematic manner complete with a control system to assure continued quality levels. 4. Standardization of product specifications is the single largest obstacle to the expansion of the shared service concept. This obstacle can be removed only through the committed involvement of the medical community. 5. The sharing of services, rather than products, appears to have great potential in terms of cost containment and the optimum utilization of facilities and equipment. 6. The acceptance of the need for policy development regarding shared services is at a low level among these administrators. There appears to be a great need for research in this area to provide guidelines

The purpose of our study was to explore multi-faceted connections between corporate welfare strategies (CWs) and local development. Although there are a large number of studies on the topic of CSR and CW, to this day, the plausible connection between CWs and local development has been largely overlooked from an academic viewpoint. Our original hypotheses assumed that there is a plausible relationship between CWs implementation and socio-economic development. In particular, CWs are likely to foster local economic diversification in related and unrelated sectors through knowledge and entrepreneurship spill-overs, as well as to strengthen local communitarian ties. Before investigating those plausible relations, we tried to put forth an acceptable, although non- conclusive, definition of corporate welfare, mainly relying on the CSR academic literature and the local development corpus of studies. Moreover, we referred to a multifaceted group of academic contributions and relied on social capital literature, Evolutionary Economic Geography’s concept of “related” and “unrelated” variety, as well as on local development studies. The mix of these three academic literatures allowed us to develop an interpretative schema that frames CWs within local development processes. In chapter 2, our analysis focused on Olivetti’s history and Adriano Olivetti’s political thought. We were inspired to dwell on this specific case for many reasons: 1) the Olivetti company is widely considered, by Italian academic literature, the ante litteram socially responsible enterprise. Therefore, for the sake of our study on CW and CSR, we could not avoid analyzing this paradigmatic case; 2) a more obvious hint came from Becattini’s comment on Porter and Kramer’s shared value (2011). Becattini’s reference to Olivetti led us to detect, what were so far, unexplored connections between Olivettian thought and Italian local development literature. Becattini’s reference to Olivetti’s case suggested an intellectual line of thought that, sometimes outwardly and often implicitly, connects AO’s social and political ideas to the local development literature. Hence, we went down this path of an ideal intellectual line of thought and reviewed Giorgio Fuà’s work (one of the few masters that Giacomo Becattini acknowledged), the theoretical cornerstones of Giacomo Becattini up to Porter and Kramer's shared value. We then proposed, relying on Olivetti’s, Becattini’s, Porter’s and Kramer’s works, a reassessment of the original concept of shared value, and called it "communitarian" shared value. We then analysed the implementation of CWs in a specific territorial context. We focused on the effects of CWs implemented by Ferrero and Miroglio, two Albese multinationals in the province of Cuneo. As aforementioned, by investigating the possible “external” effects that stem from larger enterprises’ CW policies - such as rising levels of local entrepreneurship, a growth in the number of firms operating in related and unrelated sectors, an increase in the levels of local trust relationships - our goal was to better understand this connection (that had never been fully explored academically) and add an original contribution to the subject of “internal” CSR with external effects. Lacking general research and quantitative data on the subject, we relied mostly on a qualitative/ethnographic approach based on a deep analysis of literary and historical works, on the results of a web-survey that we administered to 28,759 enterprises in the province of Cuneo and on approximately 80 in-depth interviews. The original hypotheses of research have not been confirmed directly. It is instead the “entrepreneurial style” of local multinationals to condition, in a sort of spurious relation, both the independent CW variable and the dependent variable “local socio-economic development”. Additionally, empirical research led us to better describe the “Cuneo system”, a macro productive system that encompasses a variety of LPSs and that present hybrid socio-economic features which we have defined as a “polycentric system of local productive systems”.

Contemporary higher education makes use of computers and the Internet more than ever before and the extent to which education is delivered via these media is only likely to increase in the future. While computer-mediated communication and education have been studied extensively, relatively little research has examined the potential impact of cultural background (e.g. social class) on students' experiences of different learning media. To address this gap, the current research uses a multi-sample (6 samples; n = 473), quasi-experimental approach to interrogate the relationship between student social class background and learning environment on various educational and individual outcomes. Examining a trichotomous (lower, middle, upper) conceptualization of social class across three distinct learning environments (face-to-face, computer-mediated, and fully-online) I find evidence of effects of student social class, learning environment and their interaction. In general, middle class students vary the least across conditions; lower class students tend to score lower on outcomes overall but with some notable exceptions for shared experience in face-to-face settings and comfort in online settings; and upper class students tend to experience a laboratory-based computer-mediated learning environment most positively. Implications for studying computer-mediated learning and social class are discussed, along with implications for real-world online education.

While capitalism can be held responsible for many of the numerous social and environmental issues that haunt us today, corporations hold great power and possibilities to compensate for the damage they cause. A solution can be the implementation of Creating Shared Value (CSV), which builds on identifying societal needs and approaching these as business opportunities. By doing so, value can be created for society whilst driving business results. The purpose of this thesis is to examine what factors influence the implementation of CSV in companies operating in Sweden. Data was collected through semi-structured interviews with experts who have worked with CSV. Factors that influence the implementation of CSV policies and practices, as well as factors that influence whether these lead to the desired goal of shared value creation have been extracted. The findings suggest that the public’s prevailing distrust towards companies’ engagement in solving social issues is the most noteworthy barrier for implementation of CSV, while managerial buy-in and understanding of the concept represent the strongest enabler. Getting lost in rhetoric and belief in the concept as well as focusing too strongly on measuring procedures illustrate the two greatest risks for implemented CSV policies and practice to become decoupled from the end goal of shared value creation.

Shared governance (SG) creates an evidence-based framework to support decision making in healthcare organizations by encouraging nursing staff ownership of nursing practice issues. This project assessed the current state of shared governance at a community hospital through: (a) deployment of Hess's Index of Professional Nursing Governance (IPNG) and the National Database of Nursing Quality Indicators (NDNQI) nursing satisfaction surveys which were open to nurses working in areas included in the SG framework at the project site, and (b) retrospective review of Unit Practice Council (UPC) and Nursing Senate (NS) minutes and agendas. Kotter's theory of change and the logic model informed interventions aimed at creating an effective SG. IPNG data were analyzed using Hess' scoring guidelines to establish total governance and subscale scores. Mean IPNG scores of nurse leaders, clinical nurse managers, and staff nurses were compared using a 1-way ANOVA based on job title, education, employment status, and shift. NDNQI results were analyzed based on benchmarked Magnet objectives and comparison to previous year's surveys. Meeting agendas and minutes were analyzed for attendance and initiation of interventions. Outcomes of this project included successful creation of a UPC on a medical telemetry unit; alignment of meeting times to promote attendance; paid access to remote meeting attendance; standardization of meeting minutes and agendas; and unit-specific, outcomes-data dashboards. Implementation of this model to improve the effectiveness of SG can lead to positive social change through improvement in the decision-making process in the nation's healthcare institutions. Inclusion of all members of the healthcare team in the decisions that impact practice helps ensure comprehensive, evidence-based, and patient-centric care.

The thesis is an attempt to find a satisfactorv grounding for universal moral rights. It attempts to ground universal moral rights in a revised version of the framework of moral reasons offered by T.M. Scanlon in What We Owe to Each Oflzer. In doing so it takes on several related projects. It makes a case for why rights generally, and universal rights in particular, are an essential part of a proper moral theory. It then attempts an extended argument in support of why the method of grounding universal rights at which I eventuallv arrive is superior to competitors. The argument encompasses both why I believe that universal rights need to be grounded in an objective meta-ethcs, and why I take the sort of irrealist cognitivism advanced by Scanlon to be the most promising form of moral objectivism. The argument is admittedly defeasible: it is not so ambitious as to try to eliminate every competing rights theory, but it purports to be strong enough to show that my theory enjoys significant adivantages over manv others. In the course of making this argument I align myself with the natural law tradition, and claim that mv position is best understood as a new natural law theory. The thesis goes on to defend many elements of the Scanlonian picture of moral reasons, but also to revise that picture in important ways, particularly by arguing that Scanlon’s contractualism is best understood to be underpinned bv an account of the sacred offered by Ronald Dworkin, and that some moral reasons are reasons we all share. The final chapter of the thesis shows how rights are derived from Scanlonian reasons, and particularly how universal rights are derived from shared reasons.

Leading philosophical accounts of joint activity, such as Michael Bratman’s account of ‘shared intentional activity’, take joint activity to be the outcome of two or more agents having a ‘shared intention’, where this is a certain pattern of mutually known prior intentions (plans) that are directed toward a common goal. With Bratman’s account as a foil, I address two lacunas that are relatively unexplored in the philosophical literature. The first lacuna concerns how to make sense of the apparently joint cooperative activities of agents that lack the capacities for planning and “mindreading” that one must have in order to be a party to a shared intention (consider, for example, the social play of young children or the cooperative hunting of non-human primates or social carnivores). The second lacuna concerns how participants (including adult human agents) are able to coordinate their actions “online”—that is, during action execution as a joint activity unfolds—without recourse to plans that specify in advance what they should do (consider the coordination involved when two friends meet and do a “high five”). Chapters 2 and 3 focus on the first lacuna, while chapters 4 and 5 focus on the second. In chapter 2, I focus on why participants must have mutual or common knowledge of each other’s intentions and beliefs in order to have a shared intention: Why must these attitudes be “out in the open”? I argue that, if participants lack the concept of belief, then one of the two main motivations for the common knowledge requirement—to filter out certain cases that intuitively aren’t cases of genuine joint activity—actually dissipates. Furthermore, a kind of “openness” that only requires of participants that they have the concept of goal but not that of belief can satisfy the other main motivation, to make sense of the idea that joint activities are non-accidentally coordinated. In chapter 3, I offer an account of a kind of joint activity in which agents such as young children and some non-human primates could participate, given what we know about their socio-cognitive capacities. In chapter 4, I argue that ‘shared intention’-accounts are unable to say much about spontaneous or skilful joint action because of the following widely accepted constraint on what one can intend: while an agent might intend—in the sense of commit to a plan—that “we” do something together, an agent cannot intend to perform “our” joint action. I reject this constraint and argue that some joint actions (such as a joint manoeuvre performed by two figure skaters) are joint in virtue of each participant having what I call ‘socially extended intention-in-action’ that overlap. In chapter 5, I review empirical work on subpersonal enabling mechanisms for the coordination of joint action. The review provides clues to what it is that enables participants to successfully coordinate their actions in the absence of plan-like intentions or beyond what such intentions specify. While what I address are lacunas rather than problems, an upshot of this thesis is that leading philosophical accounts of joint activity may have less explanatory scope than one might otherwise be led to believe. The accounts of joint activity and joint action that are presented in this thesis are arguably applicable to many of the joint activities and joint actions of adult human beings. The account also helps us avoid the false dichotomy between a very robust form of joint activity and a mere concatenation of purely individualistic actions—a dichotomy that accounts such as Bratman’s arguably invite us to adopt.
