Towards a design of HMO, an integrated hardware microcode optimizer

This paper discusses an algorithm for optimizing the density and parallelism of microcoded routines in micro-programmable machines. Besides presenting the algorithm itself, this research also analyzes the algorithm\u27s uses, design integration problems, architectural requirements, and adaptability to conventional machine characteristics. Even though the paper proposes a hardware implementation of the algorithm, the algorithm is viewed as an integral part of the entire microcode generation and usage process, from initial high-level input into a software microcode compiler down to machine-level execution of the resultant microcode on the host machine. It is believed that, by removing much of the traditionally time-consuming and machine-dependent microcode optimization from the software portion of this process, the algorithm can improve the overall process --Abstract, page ii

Decimal-base binary logic (DBBL) adders and registers

This paper discusses a new type of base n adder and storage register. This new type of logic is called n-base binary logic , or NBBL. The NBBL system is compared and contrasted with the Post base n system (a type of n-valued logic), the binary-coded base n system, and the straight binary system. The main purpose of this paper is to show that a decimal, or base 10, system can have some important inherent advantages over a binary system, such as greater daily operational efficiency. Furthermore, it is shown that a decimal-base binary logic system, or DBBL system, has inherent advantages over the Post and binary-coded decimal systems. A cost analysis of the DBBL system relative to the straight binary system is performed and several circuit realizations for general NBBL adders and storage registers are shown. Two of the storage register realizations are SCR models that the author has actually built and thoroughly tested --Abstract, page ii

Emotional interactions and an ethic of care: caring relations in families affected by HIV and AIDS

In the context of global processes of economic restructuring, the HIV and AIDS epidemic and socio-cultural constructions of care, many women and young people in low-income households have been drawn into caring roles within the family. Drawing on the literature on an ethics of care, emotional geographies and embodiment, this paper examines the emotional dynamics of the caring process in families affected by HIV and AIDS. Based on the perspectives of both ‘caregivers’ and ‘care-receivers’ from research undertaken in Namibia, Tanzania and the UK, we examine the everyday practices of care that women and young people are engaged in and explore how emotions are performed and managed in caring relationships. Our research suggests caregivers play a crucial role in providing emotional support and reassurance to people with HIV, which in turn often affects caregivers' emotional and physical wellbeing. Within environments where emotional expression is restricted and HIV is heavily stigmatised, caregivers and care-receivers seek to regulate their emotions in order to protect family members from the emotional impacts of a chronic, life-limiting illness. However, whilst caregiving and receiving may lead to close emotional connections and a high level of responsiveness, the intensity of intimate caring relationships, isolation and lack of access to adequate resources can cause tensions and contradictory feelings that may be difficult to manage. These conflicts can severely constrain carers' ability to provide the ‘good care’ that integrates the key ethical phases in Tronto's (1993) ideal of the caring process

On the relational dynamics of caring: a psychotherapeutic approach to emotional and power dimensions of women’s care work

Care is double-edged and paradoxical, inspiring a vast range of strong feelings in both care-givers and care-recipients. This paper draws on ideas about psychotherapeutic relationships to offer a theorisation of the complex emotional and power dynamics and imaginative geographies of care. Examining the humanistic approach developed by Carl Rogers as well as the psychoanalytic tradition, I advance an interpretation of psychotherapeutic practices that foregrounds the fundamental importance of the emotional and power-inflected relationship between practitioners and those with whom they work. I show how different traditions offer conceptualisations of the shape of therapeutic relationships that are highly relevant to consideration of the emotional and power dynamics of giving and receiving care. Against this background I discuss current debates about care, emotions and power, drawing especially on feminist and disability perspectives and arguing that psychotherapeutic approaches offer a powerful lens through which to understand the emotional and power dynamics of caring relationships. I conclude by emphasising how this theorisation helps to illuminate ubiquitous features of women’s care work
