Assessment of wilderness quality using the analytic hierarchy process

Wilderness is a unique environmental resource that provides a multitude of use and non-use benefits. The use and management of wilderness depend on the assessment of wilderness quality. Current wilderness assessment in Australia is based on two broad criteria, the remoteness and naturalness of the wilderness, determined using geographic information systems. This paper discusses a complementary assessment method using the Analytic Hierarchy Process (AHP). The AHP can be used to incorporate additional criteria, such as social and cultural criteria, to improve the quality of wilderness assessment. It provides a flexible and compatible method for large-scale wilderness assessments with multiple criteria. The weighting factors for the different criteria can be obtained from expert panels and focus groups.

An index of diet and eating patterns is a valid measure of diet quality in an Australian population

Diet indices represent an integrated approach to assessing eating patterns and behaviors. The aim of this study was to develop a comprehensive food-based dietary index to reflect adherence to healthy eating recommendations, evaluate the construct validity of the index using nutrient intakes, and evaluate this index in relation to sociodemographic factors, health behaviors, risk factors, and self-assessed health status. Data were analyzed from adult participants of the Australian National Nutrition Survey who completed a 108-item FFQ and a food habits questionnaire (n = 8220). The dietary guideline index (DGI) consisted of 15 items reflecting the dietary guidelines, including dietary indicators of vegetables and legumes, fruit, total cereals, meat and alternatives, total dairy, beverages, sodium, saturated fat, alcoholic beverages, and added sugars. Diet quality was incorporated using indicators relating to whole-grain cereals, lean meat, reduced/low fat dairy, and dietary variety. We investigated associations between the DGI score, sociodemographic factors, health behaviors, chronic disease risk factors, and nutrient intakes. We found associations between the DGI scores and sex, age, income, area-level socioeconomic disadvantage, smoking, physical activity, waist:hip ratio, systolic blood pressure (males only), and self-assessed health status (females only) (all P < 0.05). Higher DGI scores were associated with lower intakes of energy, total fat, and saturated fat and higher intakes of fiber, β-carotene, vitamin C, folate, calcium, and iron (P < 0.05). This food-based dietary index is able to discriminate across a variety of sociodemographic factors, health behaviors, and self-assessed health and reflects intakes of key nutrients.

The resident assessment instrument-minimum data set 2.0 quality indicators : a systematic review

Background
The Resident Assessment Instrument-Minimum Data Set (RAI-MDS) 2.0 is designed to collect the minimum amount of data to guide care planning and monitoring for residents in long-term care settings. These data have been used to compute indicators of care quality. Use of the quality indicators to inform quality improvement initiatives is contingent upon the validity and reliability of the indicators. The purpose of this review was to systematically examine published and grey research reports in order to assess the state of the science regarding the validity and reliability of the RAI-MDS 2.0 Quality Indicators (QIs).

Methods
We systematically reviewed the evidence for the validity and reliability of the RAI-MDS 2.0 QIs. A comprehensive literature search identified relevant original research published, in English, prior to December 2008. Fourteen articles and one report examining the validity and/or reliability of the RAI-MDS 2.0 QIs were included.

Results
The studies fell into two broad categories, those that examined individual quality indicators and those that examined multiple indicators. All studies were conducted in the United States and included from one to a total of 209 facilities. The number of residents included in the studies ranged from 109 to 5758. One study conducted under research conditions examined 38 chronic care QIs, of which strong evidence for the validity of 12 of the QIs was found. In response to these findings, the 12 QIs were recommended for public reporting purposes. However, a number of observational studies (n=13), conducted in "real world" conditions, have tested the validity and/or reliability of individual QIs, with mixed results. Ten QIs have been studied in this manner, including falls, depression, depression without treatment, urinary incontinence, urinary tract infections, weight loss, bedfast, restraint, pressure ulcer, and pain. These studies have revealed the potential for systematic bias in reporting, with under-reporting of some indicators and over-reporting of others.

Conclusion
Evidence for the reliability and validity of the RAI-MDS QIs remains inconclusive. The QIs provide a useful tool for quality monitoring and to inform quality improvement programs and initiatives. However, caution should be exercised when interpreting the QI results and other sources of evidence of the quality of care processes should be considered in conjunction with QI results.

A critical evaluation and comparison of two formative measures of system quality using criterion variables

Evaluating the validity of formative variables has presented ongoing challenges for researchers. In this paper we use global criterion measures to compare and critically evaluate two alternative formative measures of System Quality. One model is based on the ISO-9126 software quality standard, and the other is based on a leading information systems research model. We find that despite both models having a strong provenance, many of the items appear to be non-significant in our study. We examine the implications of this by evaluating the quality of the criterion variables we used, and the performance of PLS when evaluating formative models with a large number of items. We find that our respondents had difficulty distinguishing between global criterion variables measuring different aspects of overall System Quality. Also, because formative indicators “compete with one another” in PLS, it may be difficult to develop a set of measures which are all significant for a complex formative construct with a broad scope and a large number of items. Overall, we suggest that there is cautious evidence that both sets of measures are valid and largely equivalent, although questions still remain about the measures, the use of criterion variables, and the use of PLS for this type of model evaluation.

Generational and cultural indicators of technology and innovation in family business

The internet revolution has affected everybody in some way. Technologies used in business range from telephones to industry-specific machinery. Mostly though, business technology has come to mean the internet. In literature concerning innovation and the adoption of technology in business, research invariably centres on small to medium businesses (SI'v1Es), as these can be defined reasonably easily. Statistics on family businesses are limited, however, because family businesses are so difficult to categorize and define.

The Australian Family Business Survey of 1993 (Institute of Chartered Accountants) determined that family business is the largest form of business ownership in Australia and represents 83% of all business enterprises, although Basu (2004) believes that over two thirds of all world-wide businesses are owned or managed by families and around half of all businesses in Australia are family businesses. The Australian Institute of Management (AIM) (2004) states that the wealth of family and private businesses is estimated at $3.6 trillion and that family firms generate 50 per cent of Australia's employment growth, account for 40 per cent of Australia's private sector output, and are a seed bed for innovation and the information of large companies.

The difficulty in defining a family business is heightened because family businesses can take many forms ranging from sole traders to private companies to public companies. Hence, when talking about family business, you could be referring to the sole trader dealing with organic produce to an IT organisation employing hundreds of staff. Basu (2004) thinks that while ordinarily, in non-family businesses, the business and family domains remain separate, the key distinctive characteristic of family businesses is that family members work together for economic purposes. In other words, the family is not merely a social unit but also an economic unit. Craig and Lindsay (2002) believe that family involvement in the business is what makes the family business different... researchers, however, cannot seem to agree as to what constitutes 'family involvement' in a business so that it can be defined as a family business and that family business is ... a business that is governed and/or managed with the intention to shape and pursue the vision of the business held by a dominant coalition that is controlled by members of the same family or a small number of families in a manner that is potentially sustainable across generations of the family or families.

Variability of soil chemistry following irrigation with recycled municipal effluent: a Great Western vineyard case study

In areas of Australia where viticultural operations have been limited by lack of an acceptable irrigation water source, considerable expansion has occurred through the use of recycled wastewater. Despite this rapid expansion, little is known of the potential impacts of the water’s chemical constituents on soil properties, or the long-term sustainability of the vineyards using the water. In order to establish the impacts of drip irrigated recycled wastewater on a vineyard in Great Western, Australia, a study comparing the soils from the vineyard inter-row and row area was undertaken. Chemical and physical properties of the soil with varying distances from the drip emitter were also investigated. During the irrigation season, significant differences between the inter-row and row area were found for several chemical parameters including pH(1:5soil/water) (P<0.001), electrical conductivity (EC1:5) (P<0.001), water-soluble sodium (WS Na+) (P<0.001), and water-soluble chloride (WS Cl-) (P<0.001). This paper will discuss differences observed between soil properties of the inter-row and vine row area, as well as the spatial distribution of solutes under the drip emitter.

Gender stereotypes and drinking cognitions as indicators of moderate and high risk drinking among young women and men

The study examined differences in gender stereotypes, restrained drinking and self-efficacy for alcohol refusal between moderate and high risk drinkers among a university sample of 301 women and 118 men. Both female and male high risk drinkers displayed a response conflict, typified by high scores on restrained drinking but low scores on self-efficacy. This pattern of response conflict was more pronounced for high risk drinking women, who also identified poorly with feminine traits (e.g. ‘nurturing’, ‘love children’, ‘appreciative’). The findings are discussed in relation to society's double standard that accepts intoxication in men but condemns it in women.

Social comparisons and negative affect as indicators of problem eating and muscle preoccupation among children

The present study examined the utilization of social comparison practices and the role of negative affect in predicting body dissatisfaction, problem eating, and muscle preoccupation among young children. Participants were 236 children aged between 8 and 10 years. Children's eating, exercising, and muscle concerns were examined using a modified version of the Children's Eating Attitudes Test (ChEAT), which included additional items pertaining to muscle bulk and exercising. Consistent with past findings, body mass index (BMI) was found to be the sole unique indicator of body dissatisfaction for both boys and girls. Utilization of social comparison practices with adults was the main unique indicator of the modified ChEAT factors for boys, while BMI was the main unique indicator of the modified ChEAT factors for girls. In addition, negative affect was associated with binging, food preoccupation, and social pressure to eat for boys and dieting and muscle preoccupation for girls. Findings are discussed in relation to previous studies with adolescents and adults.

The management of subjective quality of life by short-stay hospital patients: an exploratory study

Background: This study tested the homeostatic model of subjective quality of life in a group of 47 short stay patients as they progressed through the stages of hospitalization for surgery.
Method: Participants completed a questionnaire measuring subjective quality of life, positive and negative affect, self-esteem, optimism and cognitive flexibility, the day prior to admission (T1), two days post-operation (T2) and one week after discharge (T3). Neuroticism and Extroversion were measured at Time 1.
Results: All variables remained stable across the three times, apart from positive affect, which dropped significantly post-operation but returned to its previous level post discharge.
Conclusion: Although the homeostatic model of subjective quality of life was supported at Time 1, the analyses raise doubts about the stability of personality. This finding is consistent with recent discussions of personality.

The reliability of clinical indicators of oxygenation: a literature review

Despite oxygen being one of the most frequently administered substances in the hospital environment, there is little empirical data regarding its use. Review of the literature regarding the clinical assessment of hypoxia and hypoxaemia reveals inconsistency in the definition of terms and raises questions as to the reliability of the clinical indicators currently used to assess the need for supplemental oxygen. Assessment of the need for supplemental oxygen and continued re-evaluation of the patient's oxygen requirements is a nursing responsibility. Physical assessment, in combination with pulse oximetry, is the most common method used by nurses to assess oxygenation status. This paper critically appraises the literature to examine the reliability of clinical indicators of oxygenation used by nurses in acute care settings.

Development of high quality university web sites: benefits to users and the learning organisation

In recent years, the online delivery of educational material has received much attention by researchers. University web sites are being used to supplement the delivery of knowledge in traditional bricks and mortar environments or as stand-alone external courses. The function of a university web site also has broader applications that can provide strategic benefits to the organisation as a whole. An Internet presence based on a high quality, easy to use web site can provide universities with a credible, professional image. This is particularly important as students and other users of university web sites expect the same high level of quality in these sites as they do from the sites of commercial organisations. This paper explores the various roles that a web site can provide to benefit higher education organisations and their customers. In addition, the paper outlines the results of a study of university web site users that identifies specific web site design features that are considered essential for a high quality university site that will meet the needs of students and other stakeholders in a university environment. By adopting these design principles, universities will be able to improve the quality of their web sites and ultimately, increase user satisfaction. Moreover, an understanding of the various roles that a web site can perform will allow universities to fully utilise the benefits of developing and maintaining an online presence while retaining their traditional role as knowledge managers.
