Gene patent practice across plant and human genomes

The uses of genetic sequences to inform, enable or create products or services for human biomedicine are substantially different from their uses in crop-based agriculture. Here, we explore what similarities and differences may emerge in patent use and strategies, and map patent-disclosed sequences onto three important plant genomes: maize (corn), rice and soybean. We focus on those referenced in the granted patent claims to compare their uses to the approach used in human gene patenting.

The ownership question of plant gene and genome intellectual properties

The restructuring of the crop agriculture industry over the past two decades has enabled patent holders to exclude, prevent and deter others from using certain research tools and delay or block further follow-on inventions

Nutrition in remote Aboriginal communities: Lessons from Mai Wiru and the Anangu Pitjantjatjara Yankunytjatjara Lands

Objective To examine the impact of efforts to improve nutrition on the Anangu Pitjantjatjara Yankunytjatjara (APY) Lands from 1986, especially in Mai Wiru stores. Methods Literature was searched in a systematic manner. In 2012, the store-turnover method was used to quantify dietary intake of the five APY communities that have a Mai Wiru (good food) store. Results were compared with those available from 1986. Prices of a standard market basket of basic foods, implementation of nutrition policy requirements and healthy food checklists were also assessed in all seven APY community stores from 2008 and compared with available data from 1986. Results Despite concerted efforts and achievements decreasing intake of sugar and increasing the availability and affordability of healthy foods, particularly fruit and vegetables, and consequent improvements in some nutrient indicators, the overall effect has been a decrease in diet quality as indicated primarily by the increased supply and proportion of energy intake from discretionary foods, particularly sugar-sweetened beverages, convenience meals and take-away foods. Conclusions The study findings reinforce the notion that, in the absence of supportive regulation and market intervention, adequate and sustained resources are required to improve nutrition and prevent diet-related chronic disease on the APY Lands. Implications This study also provides insights into food supply/security issues affecting other remote Aboriginal communities and wider Australia.

A multiscale study on the structural and mechanical properties of the luffa sponge from Luffa cylindrica plant

Cellular materials that are often observed in biological systems exhibit excellent mechanical properties at remarkably low densities. Luffa sponge is one of such materials with a complex interconnecting porous structure. In this paper, we studied the relationship between its structural and mechanical properties at different levels of its hierarchical organization from a single fiber to a segment of whole sponge. The tensile mechanical behaviors of three single fibers were examined by an Instron testing machine and the ultrastructure of a fractured single fiber was observed in a scanning electronic microscope. Moreover, the compressive mechanical behaviors of the foam-like blocks from different locations of the sponge were examined. The difference of the compressive stress-strain responses of four sets of segmental samples were also compared. The result shows that the single fiber is a porous composite material mainly consisting of cellulose fibrils and lignin/hemicellulose matrix, and its Young's modulus and strength are comparable to wood. The mechanical behavior of the block samples from the hoop wall is superior to that from the core part. Furthermore, it shows that the influence of the inner surface on the mechanical property of the segmental sample is stronger than that of the core part; in particular, the former's Young's modulus, strength and strain energy absorbed are about 1.6 times higher. The present work can improve our understanding of the structure-function relationship of the natural material, which may inspire fabrication of new biomimetic foams with desirable mechanical efficiency for further applications in anti-crushing devices and super-light sandwich panels.

Plant height affects Fusarium crown rot severity in wheat

Effects of plant height on Fusarium crown rot (FCR) disease severity were investigated using 12 pairs of near-isogenic lines (NILs) for six different reduced height (Rht) genes in wheat. The dwarf isolines all gave better FCR resistance when compared with their respective tall counterparts, although the Rht genes involved in these NILs are located on several different chromosomes. Treating plants with exogenous gibberellin increased FCR severity as well as seedling lengths in all of the isolines tested. Analysis of the expression of several defense genes with known correlation with resistance to FCR pathogens between the Rht isolines following FCR inoculation indicated that the better resistance of the dwarf isolines was not due to enhanced defense gene induction. These results suggested that the difference in FCR severity between the tall and dwarf isolines is likely due to their height difference per se or to some physiological and structural consequences of reduced height. Thus, caution should be taken when considering to exploit any FCR locus located near a height gene.

Family violence in culturally and linguistically diverse communities: An evaluation of a family relationship centre

Federal legislative changes in Australia have sought to improve how family relationship centres (FRCs) can be more responsive to culturally and linguistically diverse (CALD) communities when addressing family disputes and family violence. Research on the prevalence of family violence against women from CALD backgrounds is sparse. This article seeks to contribute to the understanding of this issue by describing findings of an evaluation of the FRC at Broadmeadows conducted by the authors. The findings focus on family violence and the appropriateness of the services offered to three CALD community groups, namely Iraqi, Lebanese and Turkish. The final section provides reflections on these findings and offers suggestions about how FRC services might better cater to the family violence needs of CALD communities by developing more extensive partnerships with community groups and by expanding the range of processes they offer beyond mediation.

Organosolv pretreatment of plant biomass for enhanced enzymatic saccharification

The combination of dwindling petroleum reserves and population growth make the development of renewable energy and chemical resources more pressing than ever before. Plant biomass is the most abundant renewable source for energy and chemicals. Enzymes can selectively convert the polysaccharides in plant biomass into simple sugars which can then be upgraded to liquid fuels and platform chemicals using biological and/or chemical processes. Pretreatment is essential for efficient enzymatic saccharification of plant biomass and this article provides an overview of how organic solvent (organosolv) pretreatments affect the structure and chemistry of plant biomass, and how these changes enhance enzymatic saccharification. A comparison between organosolv pretreatments utilizing broadly different classes of solvents (i.e., low boiling point, high boiling point, and biphasic) is presented, with a focus on solvent recovery and formation of by-products. The reaction mechanisms that give rise to these by-products are investigated and strategies to minimize by-product formation are suggested. Finally, process simulations of organosolv pretreatments are compared and contrasted, and discussed in the context of an industrial-scale plant biomass to fermentable sugar process.

Social and physical environments in senior communities: The Finnish experience

Purpose ��� The purpose of this paper is to discuss residents��� views of social and physical environments in a co-housing and in a senior housing setting in Finland. Also, the study aims to point out important connections between well-being and built environment. Design/methodology/approach ��� The data include interviews and survey responses gathered in the cases. The results and analysis are presented at different case study levels, with the discussion and conclusions following this. Findings ��� The findings show that the physical environment and common areas have an important role to activate residents. When well-designed common areas exist, a higher level of engagement can be achieved by getting residents involved in the planning and running of activities. Research limitations/implications ��� This paper discusses residents��� experiences in two Finnish housing settings and it focuses on the housing market in Finland. Practical implications ��� The findings encourage investors and housing operators to design and invest common areas which could activate residents and create social contacts. Also, investors have to pay attention to the way these developments are managed. Originality/value ��� This study is the first to investigate the Finnish co-housing setting and compare social and physical environments in a co-housing and a senior house.

Awareness and attitudes toward age-restricted communities in Finland

The average population age has been increasing for decades. In the U.S., the history of retirement communities in some states is relatively long, reaching back to the 1920s. In Finland, with one of the fastest-growing elderly population and highest total dependency ratios, seniors housing is a relatively new market within the residential housing business. Some studies have reported that only a small percentage of seniors are willing to move into age-restricted communities in Finland. This study analyzes awareness and attitudes of Finnish people toward age-restricted housing for seniors and toward seniors living in these communities. The results show that the majority of Finns were undecided if ���senior houses��� were the same as assisted living facilities. The respondents associated age-restricted communities with institutional housing for lonely elderly people with illnesses. The results of this study will help investors and developers understand how potential customers see age-restricted housing for seniors. Also, managers of senior houses can use the results for clarifying the idea of senior houses.

Social media for social good: Value creation in social media based cause brand communities

This thesis presents a case study of value creation in the social media based brand communities of two Australian cause organisations. It improves understanding of how value is created in this increasingly important environment by examining participants' posts and practices, organisational strategies and supporters' perceptions of value creation. The thesis shows that while value creation is complex, value is generated for supporters and organisations alike, and positively influences the outcomes for recipients of the vital services provided by the cause organisations. Value creation in this context thus manifests social good for supporters, service recipients and society at large.

Drink driving among Indigenous Australians in outer regional and remote communities and development of a drink driving program: A summary of findings and recommendations

Drink driving is a leading cause of criminal justice system contact for Indigenous Australians. National and state strategies recommend Indigenous road safety initiatives are warranted. However, there is sparse evidence to inform drink driving-related preventive and treatment measures. Using quantitative and qualitative methods, the study examines the profile of Queensland���s Indigenous drink drivers using court convictions and identifies the contributing psycho-social, cultural and contextual factors through qualitative interviews.
