Potential of genetics for aquaculture development in Africa

Aquaculture in Africa is fairly insignificant by world standards and accounts for a mere 0.4 per cent of global aquaculture production. The application of genetics can play an important role in efforts to increase aquaculture production in Africa through methods such as selective breeding, hybridization, chromosome manipulation and use of YY “supermales”. Other issues that need to be addressed are limited genetic research facilities, funding, human capacity and suitable species for aquaculture.

Uses of expertise:Sources, quotes, and voice in the reporting of genetics in the news

Science journalists call upon experts for background and for clarification and comment on scientific findings. This paper examines how science writers choose and use experts, and it focuses on several cases of reporting about genetics and behavior. Our research included two sources of data: interviews with 15 science reporters and three print media samples of coverage of genetics and behavior - alcoholism (between 1980-1995), homosexuality (in 1993 and 1995), and mental illness (between 1970-1995). Science reporters seek relevant and specific experts for nearly every story. Good sources are knowledgeable, are connected to prestigious institutions, are direct and articulate and don't overqualify statements, and they return phone calls. The mean number of experts quoted was 2.8 per story, differing for alcoholism (3.5), homosexuality (2.8), and mental illness (2.6). Researchers and scientists predominated among experts quoted. Quotes were used to provide context, give legitimization, as explication, to provide a kind of balance, and to outline implications. For the homosexuality sample, a significantly greater percentage of activists and advocates were quoted (21 percent compared with 5 percent and 1 percent in other samples, X <0.0001). "Lay" quotes for alcoholism and mental illness were minimal. Except for homosexuality, whose advocates are organized, those "affected" do not have a voice in genetics news stories.

Neural pathways mediating cross education of motor function

Cross education is the process whereby training of one limb gives rise to enhancements in the performance of the opposite, untrained limb. Despite interest in this phenomenon having been sustained for more than a century, a comprehensive explanation of the mediating neural mechanisms remains elusive. With new evidence emerging that cross education may have therapeutic utility, the need to provide a principled evidential basis upon which to design interventions becomes ever more pressing. Generally, mechanistic accounts of cross education align with one of two explanatory frameworks. Models of the 'cross activation' variety encapsulate the observation that unilateral execution of a movement task gives rise to bilateral increases in corticospinal excitability. The related conjecture is that such distributed activity, when present during unilateral practice, leads to simultaneous adaptations in neural circuits that project to the muscles of the untrained limb, thus facilitating subsequent performance of the task. Alternatively, 'bilateral access' models entail that motor engrams formed during unilateral practise, may subsequently be utilised bilaterally - that is, by the neural circuitry that constitutes the control centres for movements of both limbs. At present there is a paucity of direct evidence that allows the corresponding neural processes to be delineated, or their relative contributions in different task contexts to be ascertained. In the current review we seek to synthesise and assimilate the fragmentary information that is available, including consideration of knowledge that has emerged as a result of technological advances in structural and functional brain imaging. An emphasis upon task dependency is maintained throughout, the conviction being that the neural mechanisms that mediate cross education may only be understood in this context. © 2013 Ruddy and Carson.

Mentorships and co-op placements as a means of heightening the need for a secondary school diploma to the education of at-risk students.--

Both educators and politicians appear to be quite concerned about a dropout rate in Ontario's public schools of some 30 percent. With the basic understanding that a high dropout rate is costly both in economic terms and in human terms, something quite obviously needs to be done to reduce the dropout rate in Ontario schools and, in doing so, ensuring Ontario and its graduates an active role in a growing global economy. This study is an exploratory pilot study in that it examined mentoring and the role that mentoring can play in assisting a student in staying in school and graduating from secondary school. Also incorporated in this is co-operative education and the role it can play, through mentoring, in making students aware of lifestyle level of employment, and of the skills necessary to obtain gainful, meaningful employment. In order to gain information on student attitudes, needs and expectations of a mentoring situation, a series of three questionnaires was used. Also, a questionnaire was distributed to the various co-operative education employers. The intent of this questionnaire was to probe the attitudes, needs and expectations of a mentoring situation from the perspective of an employer. The findings of this study indicated that co-operative education and mentoring are a very valuable and useful component in education. There exist certain factors in a co-operative education setting that serve to enhance and to augment the traditional or "theoretical" setting of the classroom. In addition, a mentoring situation tends to add a sense of relevance to education that students seem to require. Also, an opportunity is offered that allows a student to practice and further refine the skills that have been taught over the course of the student's academic life. Results from this study suggested that a mentoring situation, occurring through a co-operative education situation, adds relevance and a sense of "application" to the traditional or classroom schooling situation. The whole idea of mentoring bodes well for the future of education and of the student. Many advantages are identified in a mentoring situation. One of the advantages is that the schools are able to work quite closely with the community and business in order to stay current and informed on the needs and expected needs of the business community. Co-operative education has now gone beyond being an "experimental" mode of education. All students can benefit from being involved in the program. Certainly at-risk students are aided with staying in school. Those students who are said to be not at-risk can also benefit from being enrolled in the program by gaining hands-on work experience and some of the necessary skills to ensure a place in a growing world economy.

Research in the clinical setting : a qualitative study of the value of play research in the continuing education of occupational therapists.

Occupational therapists have always recognized playas an important part of a child's life. However, until recently play has been viewed as a medium for reaching treatment goals, rather than as an activity that is valuable in and of itself. If occupational therapists think of playas the primary activity or occupation of childhood, then play should be a very important area of focus for paediatric clinicians. In order to assist children to become as independent as possible with play and to have fulfilling play experiences the occupational therapist needs to have a clear understanding of how to assess, set goals which lead towards competence in play, and promote play. Recent play literature has placed importance on play behaviours and looking at the relationship between the child and both the human and nonhuman environment. Believing that play and playfulness can and should be promoted, for children with physical disabilities, requires that therapists learn new assessment and intervention strategies. A new assessment tool, The Test of Playfulness, was developed by Bundy in 1994. It addressed play behaviours and environmental influences. The author, a co-investigator and eight occupational therapists were involved in a playfulness study using this test to compare the playfulness of children with physical disabilities with their able-bodied peers. After the study was completed the author questioned whether or not involvement in the playfulness study was enough of a change agent to bring about transformative learning in order to further the eight occupational therapists' education about play.This study investigated changes in either the therapists' thinking about play or their behaviour in their clinical practice. The study also examined the participants' retention of knowledge about the Test of Playfulness. The eight therapists who had been involved in the playfulness study (participants) were matched with eight therapists who had not been involved (nonparticipants). The therapists were interviewed 9 to 12 months after completion of the playfulness study. They were asked to describe various scenarios of play and open ended prompts were used to elicit the therapists' perceptions of play, good play, the role or value of play, environmental and gender influences on play, play assessment and intervention, and play research, for children with and without disabilities. The participants were also prompted to discuss their experience with the playfulness study. A self-report questionnaire was also completed at the end of the interview. The results of the study demonstrated that: (a) the play research project was a good format for continuing the participants' education about play; (b) their thinking had changed about play; (c) according to self report, they had used this new knowledge in their clinical practice; and (d) the participants remembered the items on the Test of Playfulness and could use them in describing various aspects of play. This study found that participating in a play research project had been an effective method of professional development. It also highlighted the need for increased awareness of the recent literature on play and the developing role of the occupational therapist in the assessment and intervention of play.

Mothers' experiences in the elementary school education of their children of mixed heritage /

This study explores the perceptions and experiences of middle-class women, mostly mothers, regarding the elementary school education of their children of mixed heritage. Because it endeavours to provide a forum in which the voices of women are considered a source of valuable information for educators, this study contributes to the fields of feminist and mothering research. Participants assign meanings to their lived experiences (Schon, 1983; van Manen 1997) and contemplate the various ways in which a mixed heritage mayor may not affect a child's schooling. Four main participants were interviewed who are mothers whose children of mixed heritage presently attend public elementary schools in Ontario, Canada. The study had an emergent design, thus allowing the researcher to make decisions as the study progressed. Three additional participants were included in the study to provide a wider perspective on the topic. These 3 additional women were the researcher herself as she explored her self-conceptual baggage (Kirby & McKenna. 1989); the researcher's mother in an attempt to consider the motherline (Lowinsky, 1992); and a volunteer non-mother of mixed ethnicity. The study involved a total of 12 individual interviews of approximately 2 hours in length. The 4 main participants and the researcher were each interviewed twice; the researcher's mother and the volunteer non-mother were each interviewed once. The researcher also attempted a focus group and kept a journal throughout the research process. Much of the analysis centers on women's interpretations of the mixed heritage experience and on their suggestions for elementary school educators. It concludes pondering on the invisibility (Chiong, 1998) of such children within the school system and calling for increased teacher education as a way to bring the mixed heritage experience out of the shadows.

Parents of the Gifted in Ontario: An Investigation of Parental Satisfaction with the Education of their Gifted Children

The opinions of parents in relation to the education of their gifted child were examined, with particular attention paid to their satisfaction and the type and amount of programming their child is receiving. This study employed a mixed methods research design that focused on parents’ experiences with gifted education programming and their perceptions and level of satisfaction with these programs. A survey was used to gather the perceptions and opinions of parents of gifted children in Ontario. The data were quantified and used to make observations in relation to differences in parental satisfaction and to provide a more thorough understanding of the experiences of parents in Ontario in regards to the education of gifted children. Information was also gathered regarding the recommendations that parents have for the improvement of education for their gifted child. The results of the study found that parents of gifted children were satisfied with the connections their child made within a gifted placement with like-minded peers and with opportunities for their children to learn in a more individualized and in-depth manner. However, parents expressed dissatisfaction with the timing of the initial gifted identification and the lack of knowledge that teachers, in both regular and specialized classrooms, have about gifted children and the types of programming best suited to these children. The results of the study also showed parental dissatisfaction with the lack of funding allocated to gifted education programs by district school boards and the lack of involvement they were allowed with respect to the education of their child.
