In code‐division multiple‐access (CDMA) systems, the number of mobile users that each cell can support is limited by the total received power or interference received at each base station (BS) and can vary with time. The total received power can be used as an indicator of traffic load in call admission control. In this paper, we propose a call admission control (CAC) scheme based on the total received power for CDMA systems supporting integrated voice/data services. Based on the current measure of the received power, we develop an algorithm to estimate the updated total received power due to a new incoming call. We analyze the optimal admission threshold for both power limited cells and interference limited cells. We model the system by a multi‐dimensional Markov chain and compute the system performance in terms of new call blocking probability, forced termination probability of voice calls, average transmission delay of data calls and outage probability. We compare our results with an existing degradation scheme.

In this chapter, the authors analyze current pre-service teachers’ reflections on the journals written by teachers from the nineteenth century and early twentieth century. They explore what the interchange reveals about pre-service teachers’ conceptions of teaching and the learning-to-teach process. The analysis focuses on the commonalities and differences between these groups of teachers. Findings are presented in a readers’ theater format in which recurring themes and meaning-making are expressed by voices from the past and by those who would be teachers.

Medicalization is the increasing social control of the everyday by medical experts. It is a key concept in the sociology of health and illness because it sees medicine as not merely a scientific endeavor, but a social one as well. Medicalization is a “process whereby more and more of everyday life has come under medical dominion, influence, and supervision” (Zola, 1983, p. 295); previously these areas of everyday life were viewed in religious or moral terms (Conrad & Schneider, 1980; Weeks, 2003). More specifically, medicalization is the process of “defining a problem in medical terms, using medical language to describe a problem, adopting a medical framework to understand a problem, or using a medical intervention to ‘treat’ it” (Conrad, 1992, p. 211). Sociologists have used this concept to describe the shift in the site of decision-making and knowledge about health from the lay public to the medical profession.

This paper examines the exercise of Black employee voice in South Africa over the past 53 years. Black workers constitute almost 4 out of every 5 workers in the country and experienced racial oppression from the time of colonisation up to the end of apartheid in 1994. They are still congregated around the lower skilled occupations with low incomes and high unemployment levels.

The paper draws on the theory of voice, exit and loyalty of Albert Hirschman, but extends voice to include sabotage as this encapsulates the nature of employee voice from about 2007 onwards. It reflects a culture of insurgence that entered employment relations from about that time onwards, but was lurking below the surface well before then.

The exercise of employee voice has gone through five phases from 1963 to mid-2016 starting with a silent phase for the first ten years when it was hardly heard at all. However, as a Black trade union movement emerged after extensive strikes in Durban in 1973, employee voice grew stronger and stronger until it reached an insurgent phase.

The phases employee voice went through were heavily influenced by the socio-political situation in the country. The reason for the emergence of an insurgent phase was due to the failure of the ruling African National Congress government to deliver services and to alleviate the plight of the poor in South Africa, most of whom are Black. The failure was due to neo-patrimonialism and corruption practised by the ruling elite and politically connected. Protests by local communities escalated and became increasingly violent. This spilled over into the workplace. As a result many strikes turned violent and destructive, demonstrating voice exercised as sabotage and reflecting a culture of insurgence.

The increasing availability and popularity of ways to capture personal memories using technologies such as digital cameras is beginning to alter the way in which personal memory images are produced, retained and circulated. Unlike the analog technologies, it is now possible to create an immediately available presence on the Internet. When examined from the perspective of voice, this phenomenon expands the potential of creating personal history narratives that could be collated together to produce a non‐institutional history of an era. This paper explores the ways in which the digital technologies can facilitate the production of such histories and what the technologies could do the sense of presence of an individual in the realm of the virtual.

This paper seeks to offer a profile of Peter Bullimore, one of the most dynamic lived experience speakers and trainers in the mental health world.

A profile of Peter is built up through an in‐depth interview by psychologist Jerome Carson. Areas covered include: his experience of hearing voices; his work in Australia and New Zealand; stigma; recovery; inspiring individuals in mental health; his personal illness and medication; the media; and changes and challenges.

Peter tells us that hearing voices are signs of a problem not an illness, and are often linked to trauma. He feels British work on recovery is in advance of that in Australia and New Zealand. He sees a day when it will no longer be necessary to use the term schizophrenia. Instead of recovery people should be thinking of discovery.

For too long the only voices that have been heard in the mental health field have been the professional voices. Peter's is one of many new inspirational voices to have emerged from the developing service user movement.

It could be argued that in Argentina, workers’ voice has never been silenced. In a legislative system protecting workers and politically and legally empowering trade unions, these organisations have historically represented workers. Voice however has never been limited to institutionalised and organisational forms. It has often exploded in informal ways out of workers’ experiences of the precariousness of their labour processes and of the contradictions generated between this and formal voice and representation. But it has also emerged in novel forms, through the occupation of factories, roads and public places, in moments of deep economic crisis or among groups of informally employed workers.

The case of Argentina certainly calls for a broader understanding of voice tied to the idea of voice as a socially and politically mediated process, through which formal and informal channels of voice can be alternatively created, destroyed and recreated.

The paper attempts to trace these multiple forms of voice in the recent social history of Argentina using ethnographic research conducted by the author.

The world of management and technology has become accustomed to the notion of “2.0” advancements and transformative innovations. Is the field of Change Management/Organizational Development itself in this story? Not enough! We re-examine the field’s foundational beliefs, practices, focus, research directions, and value add. We conclude that there is strong evidence from the front line and from an IBM Case Study that the field must “reboot” – to rethink our methods and frameworks; the role and skills of change leadership for the future; change practitioner capabilities for the future; the metrics needed to evaluate progress; and the knowledge exchange between Academe and practitioners.

This paper aims to categorize users of voice assistants and analyze decision-making conflicts to predict intention to adopt voice commerce (v-commerce).

This exploratory study used expert survey-based data collection founded on data saturation.

This study identifies three forms of voice systems based on senses aroused (screen first, voice only and voice first) and four profiles of voice users (passive resistant, hedonistic adopter, utilitarian adopter and active resistant), each with a different appraisal of the benefits and costs of v-commerce adoption and the experiences (positive or negative) felt during the shopping experience. This study proposes a conceptual model to predict intention to adopt v-commerce depending on voice-system and -user characteristics.

Learning from this study can help improve the marketing strategies and actions put in place by voice-assistant brands and advertisers by providing insights for adapting product recommendation algorithms to meet the needs of the identified profiles.

This paper provides an answer to the limits of classical approaches based on “one-size-fits-all” strategy by showing how voice-assistant users have different profiles that span a gradient of advance in technology adoption.
