Selection of a voice for a speech signal for personalized warnings: the effect of speaker's gender and voice pitch

There is an increasing interest in multimodal technology-based warnings, namely those conveying speech-warning statements. This type of warning may be tailored to the situation as well as to the target user's characteristics. However, more information is needed on how to design these warnings in a way that ensures intelligibility, promotes compliance and reduces the potential for annoyance. In this context, this paper reports an exploratory study whose main purpose was to assist the selection of a synthesized voice for a subsequent compliance study with personalized (i.e., using the person's name) technology-based warnings using Virtual Reality. Participants were requested to listen to speech signals, gathered from a speech synthesizer and post-processed in order to change the pitch perception, and then these were evaluated by fulfilling the MOS-X questionnaire. After that, the participants ranked the voices according to their preference. The effects of the speaker's gender and voice pitch, on both ratings and ranking were assessed. The preference of the male and female listeners for a talker's voice gender was also investigated. The results show that participants mostly prefer as first choice the high-pitched female voice, which also gathered the highest overall score in the MOS-X questionnaire. No significant influence of the participants' gender was found on the assessed measures.     

External costs: Myth or rationale for state intervention?

The paper considers the extent to which problems of environmental pollution can be left to the market system. The concept of external cost is used to establish the presumption that market forces will lead to excessive pollution. The performance criterion, that of Pareto efficiency, leading to this presumption is discussed. It is shown that for significant problems of pollution it is not possible to limit the role of the state to that of re-defining property rights. What is necessary is state intervention by way of the taxing, or regulation, of discharges into the environment: where external effects are undepletable, markets cannot meet the requirements of Pareto efficiency. Government intervention to meet such requirements requires that the government has information which is, in practice, either unavailable or very costly. Intervention towards more restricted goals is discussed. It is shown that arguments to the effect that the role of the state can be restricted to defining private property rights are based on assumptions which are irrelevant to significant problems. In particular, it is argued that a recent publication by the Institute of Economic Affairs does not, as claimed, show either that external costs do not exist, or that they exist but imply a minor role for the state in the protection of the natural environment.     

Women,Economic Development,and HIV/AIDS: Transforming Systems of Care for Sustainable Change

ABSTRACT

In this concept article, the authors utilize Maslow's Hierarchy to define and discuss a proposed conceptual treatment framework that includes economic development efforts with examples of successes that have been demonstrated in the literature. The authors posit that HIV/AIDS treatment practitioners should not overlook the interconnectedness and interdependency of economic equilibrium and public health and suggest that the creation of treatment plans based on multi-dimensional interdisciplinary approaches are necessary to achieve maximum benefit for care and resource dollars.     

Rendering Relations/Figuring Paint: The Work of Marlene Dumas in Measuring Your Own Grave

Measuring Your Own Grave is the title of a major U.S. midcareer retrospective of the work of Marlene Dumas that was on view at the Museum of Modern Art in New York City in winter 2008/2009. The exhibition presented a vast body of figurative and portrait paintings as well as drawings, notebooks, writing, and collage. Dumas's concentrated work presents the viewer with particularly powerful images that remind one of the corporeal links between public and private life. The work challenges our particular ways of viewing and naming what we see. When looking at the others within her paintings, we are little able to escape looking too at ourselves. This article is an attempt to examine what in Dumas's work makes this so.     

The Subject of History/The Object of Transference

Rather than consider the patient's history as limited to the first years of life, this paper extends the idea of the patient's history to encompass multiple histories–national, colonial, racial, gendered, sexual, developmental, familial, and immigrant–as interweaving threads of personal identity. From this perspective history refers not only to an individual's developmental course but also to the shaping force of events in creating culture or the very subjects that experience culture and cultural events. Within the performative theater of transference, countertransference histories are actually remade through the intimacies of psychic and affective experience revealed in the analytic encounter.
