Performance of balanced two-stage empirical predictors of realized cluster latent values from finite populations: A simulation study

Predictors of random effects are usually based on the popular mixed effects (ME) model developed under the assumption that the sample is obtained from a conceptual infinite population; such predictors are employed even when the actual population is finite. Two alternatives that incorporate the finite nature of the population are obtained from the superpopulation model proposed by Scott and Smith (1969. Estimation in multi-stage surveys. J. Amer. Statist. Assoc. 64, 830-840) or from the finite population mixed model recently proposed by Stanek and Singer (2004. Predicting random effects from finite population clustered samples with response error. J. Amer. Statist. Assoc. 99, 1119-1130). Predictors derived under the latter model with the additional assumptions that all variance components are known and that within-cluster variances are equal have smaller mean squared error (MSE) than the competitors based on either the ME or Scott and Smith`s models. As population variances are rarely known, we propose method of moment estimators to obtain empirical predictors and conduct a simulation study to evaluate their performance. The results suggest that the finite population mixed model empirical predictor is more stable than its competitors since, in terms of MSE, it is either the best or the second best and when second best, its performance lies within acceptable limits. When both cluster and unit intra-class correlation coefficients are very high (e.g., 0.95 or more), the performance of the empirical predictors derived under the three models is similar.

Patriarchal values : girls are more apt to change

Patriarchal values: girls are more apt to change How has the family value system changed between generations, especially when taking into account the gender dimension? This article presents some results from a study carried outin 2007 in one village of the Gourani tribe where the people are followers of Ahle Hagh in Islamabad Gharb (west of Iran). The differences between generations (those born and raised before and after the Islamic Revolution) in patriarchal values in the family are statistically significant. The older generation opts for the man of the family to make most of the decisions; on children’s education, marriage, naming, the families expenditure, the place for residence, the social network of the family and even the number of children. The younger generation has a different value system and it has moved towards a more egalitarian type of family. With the gender variable included in the findings we see that although the values of the younger male population have evolved toward a less patriarchal decision making structure inthe family, the degree of changes among the young women is much higher. Looking into the preferences for male sex for the first child as well as a larger number of boys in the family, the difference between generations is significant. However data on the differences analyzed with the gender variable proves that the changes concerning the equality of sexes are mainly due to drastic changes in the young women’s value system. That is, the male population, young or old, still prefer to have a boy as their first born and to have more sons in the family. But the young female generation in the rural area sees less difference in having boys or girls in the family. It is concluded that reforms in the old value system is an evolving process of everyday life and that the girls are the main social force for change.

Torrenting values, feelings and thoughts : cyber nursing and virtual self care in a breast augmentation forum

Earlier research shows that breast augmentation is positively correlated with positive psychological states. The aim of this study was to explore the shared values, feelings, and thoughts within the culture of breast enlargement among women visiting Internet-based forums when considering and/or undergoing esthetic plastic surgery. The study used a netnographic method for gathering and analyzing data. The findings show that the women used the Internet forum to provide emotional support to other women. Through electronic postings, they cared for and nursed each others’ anxiety and feelings throughout the whole process. Apart from the process, another central issue was that the women's relationships were frequently discussed; specifically their relationship to themselves, their environment, and with the surgeons. The findings suggest that Internet forums represent a channel through which posters can share values, feelings, and thoughts from the position of an agent of action as well as from a position as the object of action. These dual positions and the medium endow the women with a virtual nursing competence that would otherwise be unavailable. By introducing the concept of torrenting as a means of sharing important self-care information, the authors provide a concept that can be further explored in relation to post modern self-care strategies within contemporary nursing theories and practice.

Today's news tomorrow : researching archival television

Television may be the most pervasive medium of mass communication but, unlike the print media. Australian television news and current affairs have largely defied the efforts of researchers to mount comprehensive retrospective research into their form and content. This paper looks at the reasons for the dearth of this research. It considers the technical and the policy issues involved in preserving Australian television and argues that media researchers need to take a greater interest in the preservation of and access to archival television.

Corners, squares and urban identities: perceptions, attitudes and values

In February 2000, the new Victorian Labor Government announced that they were removing the western shard from Lab Architecture Studio's winning Melbourne Federation Square design. then under construction. The specific 'contested terrain' at the intersection of Flinders Street and Swanston Street Walk. Melbourne, allows the exploration of the politics of place construction over time, through an examination of Young and Jackson's Hotel [1861]. St Paul's Cathedral [1886). Flinders Street Station [1912]. the Westin Hotel [1999) and Federation Square. This site brings together architectural and social history, questions public space and identity, and looks at Melburnian's perceptions, attitudes and values. It further demonstrates that the fragmentation of the professions, and fragmentary histories. lead to the preservation of 'bits' of architecture and the destruction of the urban/landscape context, jeopardizing the Identity of place.

Public and stakeholder values of wildlife in Victoria, Australia

This paper explores the management implications of a recent study that was designed to explore public and stakeholder values of wildlife in Victoria, Australia. Questionnaires (n = 1431) were used to examine values and knowledge of wildlife held by residents from seven Victorian municipalities and members of six wildlife management stakeholder groups. The results suggest that most Victorians have a relatively strong emotional attachment to individual animals (the humanistic value) and are interested in learning about wildlife and the natural environment (the curiosity/learning/interacting value). In comparison, the negativistic, aesthetic, utilitarian-habitat and dominionistic/wildlife-consumption values were not expressed as strongly. These findings suggest that wildlife managers should expect support for wildlife management objectives that reflect the relatively strong humanistic orientation of Victorians and tailor management and education programs to appeal to this value and Victorians' interest in learning about wildlife.

Just 'good and bad news'? Disciplinary imaginaries of head teachers in Australian and English print media

Australian and English print media are actively engaged in producing reports that claim to find the 'best schools', the 'real state of education', and 'star head teachers'. This article considers the production of knights and dames, maverick heads and struggling schools. It argues that some of these stories are clearly the products of departmental press bureau activities and policy agendas. It shows, however, that even those stories intended to critique government policy support paradoxically a notion of the singular importance of the headship and the virtues of heroic leadership. It is suggested that the simulacrum of the heroic head works as a normative disciplinary device for performative and market practices and is singularly off-putting to both serving and aspirant school leaders.

Segmentation of special event attendees using personal values: relationships with satisfaction and behavioural intentions

This article presents the findings from research undertaken within a conceptual framework that included personal values, satisfaction and post-consumption behavioural intentions. The findings of a quantitative study (n = 354) conducted at a theatre-event indicate that attendees who were more inclined to place importance on their 'connectedness' with others were generally more satisfied with their attendance overall and with most of the attributes of the special event that were measured. Similar results were also found for attendees' post-con-sumption behavioural intentions; however, other personal value systems, such as that associated with hedonism, also emerged as important. These results can be used by managers and marketers of special events to enhance the special event experience and contribute to the industry's sustainability.

The relationship between patient blood pathology values and patient falls in an acute-care setting : a retrospective analysis

Few studies have investigated the relationship between patient falls and patient blood pathology values, which can reveal objective information about the health and nutritional status of a patient. It could be that some abnormal values are associated with patients that fall. The objectives of the current study were to determine whether blood pathology values were different in patients who fell compared to patients who did not fall, and whether there was a difference in the type and number of currently documented risk factors for falls found for patients who fell compared to patients who did not fall. A retrospective audit of patient incident reports and medical records was conducted in an acute-care hospital for 220 patients who fell and who did not fall. Faller and non-faller patients were matched by casemix type and length of stay. Findings revealed a significant relationship between patients who fell and the variables of age, confusion status and alkaline phosphatase blood values.

Australians' organic food beliefs, demographics and values

Purpose – To examine consumers' beliefs about organic foods and their relationship with socio-demographics and self-transcendence (universal, benevolence) personal values.

Design/methodology/approach – A random questionnaire-based mail survey of 500 Australian (Victorian) adults (58 per cent response) was used. The questionnaire included items on organic food beliefs, the importance of self-transcendence values as guiding principles in life, and socio-demographics. Statistical analyses included cross-tabulations of organic food beliefs by socio-demographics and multiple regression analyses of positive organic food beliefs with personal value and socio-demographic items as the independent variables.

Findings – The majority of participants believed organic food to be healthier, tastier and better for the environment than conventional food. However, expense and lack of availability were strong barriers to the purchasing of organic foods. Generally, women were more positive about organic food than men (e.g. women were more likely to agree that organic food has more vitamins/minerals than conventional food). The personal value factor related to nature, environment and equality was the dominant predictor of positive organic food beliefs, followed by sex. These predictors accounted for 11 per cent of the variance.

Research limitations/implications – A survey response bias needs to be taken into account. However, the response rate was adequate for reporting and differences in age and education between participants and the Victorian population were taken into account in data presentation. Future understanding of consumers' use of organic foods will require the inclusion of a fairly extensive set of potential influences.

Practical implications – Communication appeals based on psychographics may be a more effective way to alter consumers' beliefs about organic foods than those based on demographic segmentation.

Originality/value – To the best of one's knowledge, this is the first study to examine the relationship between personal values, socio-demographics and organic food beliefs in a random population sample. This study is relevant to producers, processors and retailers of organic food and those involved with food and agricultural policy.
