Using an IDMI methodology to make multi-criteria decisions

Multi-criteria decisions usually require measurement or evaluation of performance in different units and their mix by application of weighting factors. This approach leads to potential manipulation of the results as a direct consequence of the applied weightings. In this paper a mechanism has been proposed to overcome this problem. It is known as the : Interlink Decision Making Index (IDMI) and has all the desired features: simple, interlink (all criteria) and automatically and quantified influence of critical criteria (i.e. no human weighting needed). The IDMI is capable of reflecting the total merits of a particular option once the normal decision making criteria and (up to two) critical criteria (CC) have been chosen. Then, without arbitrarily weighting criteria, comparison and selection of the best possible option can be made. Simple software has been developed to do this numerical transfer and graphic presentation. Two hypothetical examples are presented in the paper to demonstrate the application of the IDMI concept and its advantages over the traditional "tabular and weighting method" in the decision making process.

Public transport and pedestrian access, the impact of suburban planning on adolescence

The following paper discusses the impact of suburban life for adolescents in relation to public transport and pedestrian access. The research compares the morphology and level of connectivity of two planning models, cul-de-sac and regular grid, with respect to two suburbs which share a similar socio-economic profile, Rowville and Caulfield. These are subsequently evaluated in terms of ABS statistics, in particular year 12 or equivalent levels of education, and transport statistics. The results of the investigation are discussed in reference to the four key tasks of adolescence (Carr-Greg & Shale 2002)', in order to establish the degree to which morphology and access levels of suburbs impact on adolescent development.

The importance of human FcyRI in mediating protection to malaria

The success of passive immunization suggests that antibody-based therapies will be effective at controlling malaria. We describe the development of fully human antibodies specific for Plasmodium falciparum by antibody repertoire cloning from phage display libraries generated from immune Gambian adults. Although these novel reagents bind with strong affinity to malaria parasites, it remains unclear if in vitro assays are predictive of functional immunity in humans, due to the lack of suitable animal models permissive for P. falciparum. A potentially useful solution described herein allows the antimalarial efficacy of human antibodies to be determined using rodent malaria parasites transgenic for P. falciparum antigens in mice also transgenic for human Fc-receptors. These human IgG1s cured animals of an otherwise lethal malaria infection, and protection was crucially dependent on human FcγRI. This important finding documents the capacity of FcγRI to mediate potent antimalaria immunity and supports the development of FcγRI-directed therapy for human malaria.

Distributions of caregiving tasks among family members: the place of gender and availability.

To extend family-oriented approaches to caregiving, participants in 2 studies were asked to distribute tasks among a set of adult children, first with information only about gender and then with systematically varied information about commitments to paid work, marriage, and/or parenting. Making the distributions, using a computer-based program, were 2 groups of older adults (ages 60 to 90 years). In Study 1, gender composition was kept constant (2 sons and 2 daughters). In Study 2, it was varied. The results showed several ways in which people combine attention to gender and to availability. The results also pointed to the need to consider both the number and type of tasks allocated. The results are discussed in terms of implications for the way caregiving is regarded, the development of multiple-factor models for variations among family members, and the possible replications and extensions to other circumstances and populations.

Extending studies of collaborative cognition by way of care giving situations

Care giving situations contain several features that offer opportunities for expanding the way that collaborative cognition is conceptualised and explored. These features are the presence of several possible contributors, more than one kind of change in participation, distinctions drawn among parts of a task, and differences in understanding based on interests. All represent departures from the traditional focus on dyads, tasks that emphasise one kind of change only, single problems, and differences in competence or expertise. All are also features likely to be found in everyday problem solving. Study 1 focuses on family contributions, based on reports by care givers about their current situation and their preferences for the involvement of other family members. Study 2 presents a standard family scenario and focuses on the views held by care givers, older adults, and community nurses about the reasonableness of various changes in participation. Results are discussed in terms of the ways situations such as care giving can help build a richer picture of collaborative cognition, one that is applicable to a variety of tasks and to all parts of the life span.

Frequency, severity and effect of life of physical symptoms experienced during pregnancy

This study aimed to: 1) describe the number, frequency, severity of discomfort and effect of symptoms on life of 29 physical symptoms women experienced at 15 to 25 weeks of gestation; 2) explore whether experiencing this group of physical symptoms more frequently and intensely was associated with a higher score of depressive symptoms and lower self-esteem; (3) examine whether discomfort and effect ratings aided prediction of well being over and above symptom frequency; and (4) investigate which individual physical symptoms contributed most to predicting depressive symptoms and self-esteem. Pregnant women (n = 215) completed the Beck Depression Inventory, Rosenberg Self-Esteem Scale, and a physical symptoms questionnaire. Frequency, discomfort, and the effect of physical symptoms all consistently correlated with higher scores for depressive symptoms, but less consistently with lower self-esteem. Discomfort and the effect of symptoms predicted variance in depressive symptoms after accounting for symptom frequency. Higher frequency, more discomfort, and the effect of fatigue and effect of flatulence were related to depressive symptoms. Relationships between pregnancy-related physical symptoms, depressive symptoms, and low self-esteem suggest that when women report any of these constellation of factors, further screening is indicated. A comprehensive assessment of physical symptoms includes frequency, discomfort, and effect on life.

My baby body : a qualitative insight into women's body-related experiences and mood during pregnancy and the postpartum

An inductive qualitative approach was employed to explore women's experiences of their body and mood during pregnancy and the postpartum. In-depth interviews were conducted with 20 perinatal women (n at late pregnancy=10; n in the early postpartum period=10). While most of the sample reported adapting positively to body changes experienced during pregnancy, the postpartum period was often associated with body dissatisfaction. Women reported several events unique to pregnancy which helped them cope positively with bodily changes (e.g. increased perceived body functionality, new sense of meaning in life thus placing well-being of developing foetus above body aesthetics, perceptual experiences such as feeling baby kick, increased sense of social connectedness due to pregnancy body shape, and positive social commentary); however, these events no longer protected against body dissatisfaction post-birth. While women reported mood lability throughout the perinatal period, the postpartum was also a time of increased positive affect for most women, and overall most women did not associate body changes with their mood. Clinical implications of these findings included the need for education about normal postpartum body changes and their timing, and the development of more accurate measures of perinatal body image.

Depressive and anxiety symptoms through late pregnancy and the first year post birth : an examination of prospective relationships

One hundred and fifty-nine women were measured for depressive and anxiety symptoms from late pregnancy through to 12 months postpartum. Partial correlations revealed stability of depressive and anxiety symptoms across time. Depressive symptoms did not predict anxiety at any time point. Anxiety predicted increases in depressive symptoms from late pregnancy to early postpartum, but not from early postpartum to mid postpartum. Anxiety predicted depressive symptoms from mid postpartum to late postpartum, however, not when social support in late pregnancy was controlled for.

Studies on Australian hydroids : the genus Eudendrium and the fauna of the seagrass Amphibolis

An important Athecate genus, Eudendrium, and a group of species of the Thecata, the latter ecologically related by life on a common substrate, are reviewed. Eudendrium, hitherto poorly known in Australia, comprises 17 species, including 10 undescribed species with 71% Australian, and high provincial endemicity. Eudendrium may be a shelf genus avoiding turbulent oceanic waters. Species of Eudendrium are predominantly epizoic and some gregariously settling colonies may live for five years. Identification of sterile material is refined by using the cnidome in a key to classification. The species and population dynamics of hydroid epiphytes of the endemic southern Australian marine angiosperm Amphibolis were investigated with revision of historically vexatious taxa. In contrast with the northern hemisphere, no Athecata are associated with southern Australian seagrasses. Seventeen species from eight thecate families are associated with the two species of Amphibolis, including one undescribed species, H&lecium amphibolum, and one new record for Australia, Aglaophenia postdentata. The Lineolariidae is revised and a new genus, Millardaria, erected for a species from seagrass in Madagascar. The high endemicity (58%) and host-specificity of hydroids to Amphibolis is an evolutionary consequence of isolation of the seagrass dating from break-up of the Tethyan Sea. Hydroids occur throughout the year in the Amphibolis leaf canopy with a mean annual epiphytism of 44% on A. antarctica in the eastern continent and 86% in the western continent; epiphytism is 52% on A. griffithii in the western continent. Half of the eight important species are dominant epiphytes across the southern continent but the species and order of abundance varies regionally. Most are pioneer colonists with short, repetetive life-cycles lasting from weeks to a few months. Three species epiphytise the seagrass stems but only one is a leaf-canopy dominant. The canopy community comprises small, fast-growing species or dwarfed variants of species larger in other habitats: these ecomorphically constant forms are associated only with seagrass. Strategies for survival in the harsh Amphibolis environment include adnate colonies and gonothecae adnate or recumbent to the substrate, marked strengthening of the hydrorhiza, various hydrodynamic adaptations of the hydrotheca, early maturation and production of numerous small ova.

Life events and cognitive processing in sexually dysfunctional individuals

The aim of this study was to make an assessment of the role of the cognitive component in the development of sexual dysfunction. Past studies have largely focused on the impact of particular events on sexual dysfunction and have not assessed the role of the perception of these events. A number of theories on sexual dysfunction have been developed to explain the influence of cognitions, but these have not been empirically tested. This study investigated the role of the cognitive evaluation of sexual experiences among 30 sexually dysfunctional participants and 30 control participants who were matched on age, marital status and biological sex. The Cognitive Aspects of Sexual Dysfunction Measure (CASDM) was constructed to evaluate sexual dysfunction. This measure was designed to tap into the major events in participants’ lives and, more importantly, the participants’ perceptions of these events. The components assessed were the intergenerational (family of origin), individual, current life and relationship aspects of the person’s life. These factors were measured from the responses to questions regarding the participant's cognitions about past experiences, the effect of the past experience on the participant at the lime it occurred and the influence this experience had on the participant's sense of self now, their relationship now and sexual functioning now. The main findings in the intergenerational area were that past experiences were perceived by the sexually dysfunctional group to be having an impact on the self, relationships and their sexual functioning although there were no actual differences between the sexually functional and the sexual dysfunctional participants in the occurrence of the event. For the individual factors, there were differences between the sexually functional and sexually dysfunctional participants in both values and lifestyle, although these were not perceived to be having an impact on the self, relationship and sexual functioning. In the relationship area, anger was the major factor separating the sexually functional and sexually dysfunctional groups. Anger was high among the sexually dysfunctional participants and was perceived to be having an impact on self, the couple’s relationship and their sexual functioning. The importance of all these variables in providing a better understanding of the cognitive factors in sexual dysfunction was discussed. The findings demonstrate the importance of cognitions in influencing sexual functioning. Clinicians should not simply deal with the life experiences of sexually dysfunctional people when attempting to change their behaviour, but should focus on changing cognitions about the behaviours in relation to sexual functioning.
