New danger from Hoary cress

HOARY CRESS is undoubtedly one of the worst weeds introduced into Australia. It is a vigorous deep rooted perennial which competes strongly with crop plants and seriously decreases yields. The importance of three recent discoveries of this weed in Western Australia therefore need hardly be stressed. G. R. W. Meadly, Offlcer-in-Charge of the Weeds and Seeds Branch, and R. D. Royce, Offlcer-in- Charge of the Botany Branch, report on two recently found infestations of hoary cross in the Great Southern, and one at Jerramongup. An intensive eradication programme is under way

Using Photovoice to Examine and Initiate Youth Empowerment in Community-Based Programs: A Picture of Process and Lessons Learned

Photovoice is a creative, participatory action research method that puts cameras in the hands of people whose voice is often hushed by the power elite, such as youth, to document issues and concerns as perceived by that group. Adult society provides youth few opportunities to positively influence the laws and regulations that govern their lives or the policies of programs in which they participate. Communitybased programs are one channel for youth to gain skills and opportunities for changing the community context in which they live. Mechanisms to facilitate youth empowerment in these programs, however, are currently vague and imprecise. Photovoice was implemented in two community-based youth programs in South Carolina to examine and initiate youth empowerment in those communities. This article details the process and lessons learned from conducting Photovoice with youth in out-of-school, community-based youth program settings. While roadblocks appeared for both the youth researchers and the universitybased investigative team, the Photovoice method was embraced by the youth who participated in the research process. Some challenges the investigative team experienced for implementation included geographic distance between the Photovoice project facilitator and the youth, challenges of working with youth and their competing commitments, an uncertainty of youth expectations, and underestimation of time and other resources

Material Strength Effect in the Shock Compression of Alumina

The Hugoniot elastic limits (HEL) of a high-density aluminum oxide ceramic (Lucalox) and a slightly lower-density ceramic (porosity approximately 4%) were determined to be 112±13 and 83±5 kbar, respectively. Above the HEL, the shock-stress-volume Hugoniot curves for both materials are offset by 40 kbar or more above their hydrostatic-pressure-volume curves. These results indicate that shear stresses with magnitudes of about 30–40 kbar persist in aluminum oxide to shock-pressure levels of at least 300 kbar

Youth Perspectives on Meaningful Participation in Community Based Programs: A Qualitative Assessment

Allowing the voiceless to have a voice is a tenet of empowerment. This paper highlights research that employed a participatory action research framework to gain a better understanding of young people’s perceptions about youth empowerment and acquire their perspective (voice) about the meaningfulness of participation in out-of-school advocacy and volunteer program activities. Using Photovoice, the research provides a missing point of view in youth empowerment model development. Results indicate that the quality of a youth’s participation in a community-based program is determined by 1) youth expressing themselves without censorship, 2) occasions for youth to expand their social networks with youth and adults, and 3) adults observing and valuing youth contributions. These findings raise implications for community-based, youth empowerment programs including program philosophy, program procedures, youth empowerment content and activities, and adult leadership style. The findings may assist practitioners when designing youth empowering activities and researchers when operationalizing youth empowerment

Risk Assessment Matrices for Workplace Hazards: Design for Usability

In occupational safety and health (OSH), the process of assessing risks of identified hazards considers both the (i) foreseeable events and exposures that can cause harm and (ii) the likelihood or probability of occurrence. To account for both, a table format known as a risk assessment matrix uses rows and columns for ordered categories of the foreseeable severity of harm and likelihood/ probability of that occurrence. The cells within the table indicate level of risk. Each category has a text description separate from the matrix as well as a word or phrase heading each row and column. Ideally, these header terms will help the risk assessment team distinguish among the categories. A previous project provided recommended sets of header terms for common matrices based on findings from a survey of undergraduate OSH students. This paper provides background on risk assessment matrices, discusses usability issues, and presents findings from a survey of people with OSH-related experience. The aim of the survey was to confirm or improve the prior recommended sets of terms. The prior recommendations for severity, likelihood, and extent of exposure were confirmed with minor modifications. Improvements in the probability terms were recommended
