Telecommunication and suicide prevention: hopes and challenges for the new century

Development of information technology has created new opportunities and challenges in suicide prevention, research, and clinical practice. This article presents an overview of the wide range of telecommunication-based suicide prevention approaches. Interventions using the Internet, telephone, and videoconferencing are discussed, including crisis intervention, referral, and support, suicide risk assessment, psychotherapy for individuals at risk, and online-based suicide prevention training and education. Research regarding effectiveness of telecommunication-based suicide prevention in various demographic and clinical populations is reviewed, as well as concerns regarding this type of intervention. Future areas of research and development in the use of telecommunication media in prevention of suicide are discussed.     

More responsibility, less control: psychiatric survivors and Welfare State restructuring

This paper is concerned with the implications of recent Welfare State restructuring for psychiatric survivors' citizenship status. Using the Province of Ontario as a case study, the paper examines the extent to which recent change in mental health care and social assistance programs has worked to facilitate or constrain survivors' ability to exercise control over their lives. Despite recognition of the importance of survivors' participation in the mental health care system in the late 1980s, recent years have seen a return to a more traditional treatment paradigm characterized by professional control. Concurrently, restructuring of social assistance programs has led to a decline in the real value of income supports and growing pressure on informal support networks. As a result, psychiatric survivors are increasingly held responsible for their own material well-being and public conduct, but are less able to exercise control within everyday life.     

ON THE ASSIGNMENT OF INDIVIDUALS TO LATENT CLASSES

Consider an m-way cross-classification table (for m = 3, 4, … ) of m dichotomous variables that describes (1) the 2 ^m possible response patterns to a set of m questions (where the response to each question is binary), and (2) the number of individuals whose responses to the m questions can be described by a particular response pattern, for each of the 2 ^m possible response patterns. Consider the situation where the data in the cross-classification table are analyzed using a particular latent class model having T latent classes (for T = 2, 3, …), and where this model fits the data well. With this latent class model, it is possible to estimate, for an individual who has a particular response pattern, what is the conditional probability that this individual is in a particular latent class, for each of the T latent classes. In this article, the following question is considered: For an individual who has a particular response pattern, can we use the corresponding estimated conditional probabilities to assign this individual to one of the T latent classes? Two different assignment procedures are considered here, and for each of these procedures, two different criteria are introduced to help assess when the assignment procedure is satisfactory and when it is not. In addition, we describe here the particular framework and context in which the two assignment procedures, and the two criteria, are considered. For illustrative purposes, the latent class analysis of a classic set of data, a four-way cross-classification of some survey data, obtained in a two-wave panel study, is discussed; and the two different criteria introduced herein are applied in this analysis to each of the two assignment procedures .     

Demography of the Firm: A Useful Metaphor?

Demography of the firm is an interdisciplinaryresearch field of economics, sociology andeconomic geography. Although the name suggestsotherwise, demographic input has been limiteduntil recently. This article argues that thedemographic viewpoint may lead to added value.The metaphor is relevant, not because firms aresimilar to biological creatures (they are not),but because there are significant parallels inthe mechanisms of population change, as aresult of selective processes of birth anddeath, as well as aging and internal change ofincumbent firms. The nature of these changeprocesses at the micro level has to be studiedusing theories from other disciplines, such aseconomics, sociology and geography; a situationquite similar to that of human demography. Thearticle compares similarities and discrepanciesbetween the processes of birth and death infirm and human populations, as well as the mostimportant dimensions of population structureand change, e.g. age, period, and cohort. Amain difference is that in addition to thesefamiliar variables in human demography, firmsize and growth, and economic activity are alsomajor dimensions of the structure of firmpopulations. Because there are stronginteractions between these variables, anydemographic analysis, for instance to determinethe age curve of mortality, should also takeinto account these variables.     

Addiction Treatment with Deaf and Hard of Hearing People: An Application of the CENAPS Model

ABSTRACT

Alcohol and drug addiction is a significant problem among deaf and hard of hearing people. Looking through a Deaf culture lens, treatment for alcohol and drug addiction is key for providing care for deaf and hard of hearing clients. Using the CENAPS model, an applied cognitive-behavioral therapy program is recommended for addiction treatment. The CENAPS model provides clinicians with tools for stabilizing deaf and hard of hearing clients, supporting their transition to early recovery. Educating the client about the stages of relapse and the stages of recovery, clinicians using this model can better treat and prepare deaf and hard of hearing clients for long-term recovery.     

Intersensory Perception at Birth: Newborns Match Nonhuman Primate Faces and Voices

Previous studies have shown that infants, including newborns, can match previously unseen and unheard human faces and vocalizations. More recently, it has been reported that infants as young as 4 months of age also can match the faces and vocalizations of other species raising the possibility that such broad multisensory perceptual tuning is present at birth. To test this possiblity, we investigated whether newborns can match monkey facial and vocal gestures. Using a paired preference procedure, in Experiment 1 we presented pairs of different visible monkey calls in silence and then in the presence of one or the other corresponding audible call and compared preferences across the silent and in‐sound conditions. In Experiment 2 , we presented the same monkey visible calls but this time together with a tone analog of the natural calls in the in‐sound trials. We found that newborns looked longer at the matching visible call in the in‐sound condition than in the silent condition in both experiments. These findings indicate that multisensory perceptual tuning is so broad at birth that it enables newborns to integrate the facial and vocal gestures of other primates and that integration is based on newborns’ detection of audio‐visual temporal synchrony relations.     

Parametric Versus Nonparametric Inference on Zenga Index of Inequality: Issues and Evidence From Survey Data

Recent growing disparities suggests to move from inequality measures based on comparing the incomes of the less fortunate with the overall mean, as the Gini, to the new Zenga index, which instead contrasts the means of the less and the more wealthy subpopulations. After providing a thorough analysis of the theoretical and practical aspects of obtaining parametric and non-parametric confidence intervals for the Zenga inequality measure, we develop a cross-regional study based on the Swiss Income and Consumption Survey, wave 2005. Results show that coverage accuracy and average length of confidence intervals improve when the parametric model offers a good fit to the data.
