This manuscript outlines the lifelong battle with severe stuttering and describes a new modality of effective amelioration of the disorder from the standpoint of a university professor and researcher in the field of stuttering. Childhood reactions to stuttering are discussed, along with the educational and vocational impact of stuttering. Ongoing therapy was received throughout the formative years and into adulthood, emphasizing reduced rates of speech. The use of Delayed Auditory Feedback (DAF) was found to induce fluent speech, but was considered only as a tool for decreasing the speech rate to achieve fluency. When fluency under DAF was discovered to be possible at faster speech rates, the possibility that the use of DAF and other forms of altered auditory feedback could themselves have an inhibitory effect on stuttering, without concomitant rate reduction was investigated. An In-The-Canal (ITC) fluency-enhancing device was used that provided DAF and Frequency Altered Feedback (FAF) to produce more fluent speech. After 10 months of use, the author was relatively free from stuttering. Speech was natural sounding, relatively spontaneous and unlaboured with an absence of fear. However, further testing (that is currently underway at various centres) is necessary before generalizations can be made.
Community psychology as a discipline has not focused its attention on the lives of lesbians, gay men, and bisexual (LGB) people, despite the field's potential to collaborate with this population in dealing with the many psychosocial challenges they face. Professional and personal barriers that community psychologists must confront conducting research and developing interventions with the LGB community are described. Community psychology work with LGB communities is often a "coming out" experience for LGB community psychologists, and a questioning of sexual orientation for heterosexual community psychologists. Conceptual analyses and empirical reports are presented that exemplify how community psychologist can contribute to decreasing the pervasive stigma LGB people face. The use of an ecological model, a focus on the development and evaluation of preventive interventions, and a recognition of the diversity within the LGB population are core perspectives that can direct future work by community psychologists. Issues ranging from testing ways to empower young LGB people to analyses of the impact of the sociopolitical climate on LGB lives demonstrate the rich range of contributions community psychologists can make.
The early years of molecular biology were characterized by a strong interaction between theory and experiment. This included the elucidation of the structure of DNA itself; genetic fine structure, recombination and repair; DNA replication; template-directed protein synthesis; the universality of the triplet genetic code, and the co-linearity of the DNA sequence of structural genes and the sequence of amino acids in proteins. The principle of co-linearity was later modified when split genes were discovered. It is suggested that accurate splicing of gene transcripts might also be template directed. In 1958 Crick proposed a 'central dogma' of molecular biology stating that information could not be transmitted from proteins to DNA. Nevertheless, proteins can chemically modify DNA, and this is now known to have strong effects on gene expression.
