How voice affects perceptions of relationship wih adults, ownership, and engagement in youth

The purpose of this study was to determine if youth voice affects the ownership and engagement experienced by youth in a county 4-H program. For the treatment group, a youth-led approach was used where having a voice included youth sharing decision-making power with the adults in the program. The comparison group consisted of 4-H members in three other clubs in the county. These youth experienced an adult-led approach where the decisions about the club programming were made strictly by the adults. The Youth Voice Survey instrument was developed to assess youths\u27 perceptions of ownership, engagement, and relationship with adults at both a pre- and post-measurement. Interviews were conducted with six youth in the treatment group to determine if their lived experiences confirmed the factors that emerged from the Youth Voice Survey. Exploratory factor analysis was used to investigate the underlying latent constructs in the instrument. Analysis of covariance was utilized to determine if differences existed between youth participating in the treatment and comparison groups and if differences existed between youth based on race. Findings indicated statistically significant differences between the treatment and comparison groups on all three constructs of ownership, engagement, and relationship with adults. Findings also indicated statistically significant differences between white and non-white youth on all three constructs of ownership, engagement, and relationship with adults. It was concluded that, in programs incorporating voice, youth experience more ownership and engagement and have a more positive relationship with adults. An implication of this study is that adults who work with youth should receive training on the incorporation of youth voice and the support of youth as decision-makers

High impact activities in parks: best management practice and future research

Off-road driving, horseriding, rock climbing and similar activities can be lucrative for tour operators and important for local recreational groups, but contentious for management of national parks and protected areas, both because of safety and liability and because of potentially high environmental impacts. These include spreading weeds and pathogens, starting fires and crushing bird nests on beaches, amongst many others. In Australia as elsewhere, off-road vehicles and horses are allowed only in some places in some parks, and often only under permit. We have very little reliable scientific information to-date on just how serious these impacts may be, and on how well they might be managed through minimal-impact practices such as vehicle washdowns, stockfeed processing and seasonal closures. Such information can only be obtained through site specific ecological studies of the plants, animals and watercourses likely to be affected, differentiating tourism impacts from natural causes and fluctuations. This report examines management strategies for these activities worldwide and in Australia. Suggestions for best management practice and future research agendas are set

Effect of lysolecithin on the oxygen uptake of tumour cells, polymorphonuclear leucocytes, lymphocytes and macrophages in vitro.

LYSOLECITHN has been widely studied as a surface-active haemolytic agent (Robinson, 1961) and has been implicated in immune haemolysis (Fischer, 1964), in hypersensitivity reactions (Middleton and Phillips, 1963, 1964), and in the delayed stage of the increase of vascular permeability in inflammation (Cotran and Majno, 1964). Fischer (1964) found that the oxygen uptake (Q02) of tumour cells was reduced by small concentrations of "lysolecithin ", while micro and macrophages responded by an increase Of Q02 and phagocytic activity. We felt that this observation should be confirmed, because it could form the basis of a therapeutic method of increasing the radiosensitivity of tumours by raising the oxygen tension (PO2), and from the theoretical aspect might clarify differences between the cell membranes of tumour and of normal cells. Moreover, Fischer's experiments are open to criticism. His cell suspension was stirred by a moving mercury seal and this could have produced cell damage from mercury poisoning. Also he treated his cell suspensions not with lysolecithin, but with complement plus a specific antibod

Designing an International Experience Program for 4-H Members in Louisiana

In recent years, the U.S. Cooperative Extension Program (CEP) has worked to develop international exchange programs (IEPs) for 4-H members in some states. However, no such program currently exists in Louisiana. As such, the purpose of this descriptive study was to identify the IEP participation preferences held by 4H members in Louisiana to inform future IEP development and implementation. 4-H members in this study preferred to participate in a short-term IEP during the summer of the 11th grade. Thus, it is recommended that IEP recruitment be geared toward students in the 9th and 10th grades. 4-H members preferred to participate in an IEP located in Europe or Australia/New Zealand. Future research should examine which characteristics of these locations appeal to 4-H members to broaden the appeal of IEPs in other locations. Career related courses and hands-on experience were perceived by 4-H members as important activities to include in the IEP design, whereas staying with a host family was not. Future research should assess whether this finding is specific to members in this study or representative of a national trend that warrants reexamination of the overall design of 4-H IEPs employed by the U.S. CEP

Techniques for improving reliability of computers

Modular design techniques improve methods of error detection, diagnosis, and recovery. Theoretical computer (MARCS (Modular Architecture for Reliable Computer Systems)) study deals with postulated and modeled technology indigenous to 1975-1980. Study developments are discussed

Looking for Information: An Exploratory Analysis to Explain Public Information-Seeking Behaviors About Mosquito Control

Mosquitoes pose substantial risks in communities worldwide, and the extent and type of such risk may vary across communities and regions. The integrated mosquito management approach integrates multidisciplinary methods into practical strategies tailored to local communities. Reduction of mosquito larval sources via community engagement in at-home mosquito control behaviors is a key component of this approach. Best methods of communicating information to the public to foster knowledge and motivation to engage in local mosquito control efforts. The purpose of this descriptional, correlational study was to describe the Florida public’s mosquito control information search behaviors, as well as examine factors that may explain those behaviors. Findings revealed statistically significant relationships existed between respondents’ information search frequency and their subjective and objective knowledge, importance of mosquito control, personal responsibility, income and education. Significant relationships were also observed between personal responsibility and homeownership and type of residence. Respondents perceived CDC websites and Florida DOH websites as the most trustworthy of the sources listed, and were most likely to use local mosquito control program websites when searching information. Local mosquito control districts should use the findings of this study to target passive audiences and facilitate their future engagement in mosquito control dialogues. Future research is needed to further examine the directionality and predictive nature of variables examined in this study
