Jackknifing in Categorical Data Analysis

Estimation of nonlinear functions of a multinomial parameter vector is necessary in many categorical data problems. The first and second order jackknife are explored for the purpose of reduction of bias. The second order jackknife of a function g(.) of a multinomial parameter is shown to be asymptotically normal if all second order partials ?²g( p )?dp_i?p_j obey a Hölder condition with exponent α>1/2. Numerical results for the estimation of the log odds ratio in a 2times2 table demonstrate the efficiency of the jackknife method for reduction of mean-square-error and the construction of approximate confidence intervals.     

Do children from small families do better?

The education, income, wealth and satisfaction with life of australians aged 25–54 are examined in relation to the circumstances of their childhood, paying particular attention to variation by number of siblings when growing up. The data are from the Household, Income and Labour Dynamics in Australia (HILDA) survery. Educational attainment, income earned and household wealth tend to be greater for people who grew up in relatively small families. The effect of the number of siblings on educational attainment is greater for females than for males. However the advantages of growing up in a smaller family do not translate into higher levels of satisfaction with life. The implications of the findings for the public debate on fertility and child-related benefits in Australia are discussed, as are the implications of a child-quality-child-quantity trade-off for the explanation of fertility levels in more developed countries.     

“Something More”: The Meanings of Marriage for Religious Couples in America

This study focused on how couples’ beliefs about marriage and religion shape the meanings they find in their marriage. Interviews about connections between religion and marriage were conducted with 57 Christian, Jewish, and Muslim couples in New England and northern California. Qualitative analyses found the major theme, common across faith traditions, was that marriage is a sacred union that is “something more": more than the self, more than the couple, and more than the family unit. To these couples marriage is divine and institutional and a vital support for their relationship. Our findings raise an interesting counterpoint to the current scholarly discourse about the deinstitutionalization and individualization of contemporary marriage. Institutionalized features of marriage may retain their strength in contemporary society as many religious couples, and perhaps many other couples as well, believe marriage is something more than the deinstitutionalized, private relationship that many scholars now see.     

Family policy and couples’ labour supply: an empirical assessment

This paper empirically examines the effect on couples’ labour supply of a universal at-birth cash benefit and a government subsidy equal to 50% of child care expenditure for working parents. The method is first to simulate the effects on labour supply over the adult lifecycle using a calibrated dynamic utility maximisation model of a representative couple, using data drawn from waves of a longitudinal survey for Australia. Then using the same data, the effect of family benefits and the child care subsidy on couples’ hours worked is econometrically estimated. The 50% child care subsidy was found to increase the average couple’s labour supply by the equivalent of 0.75 to 1 h per week whilst children are of pre-school age, and less on average over the couple’s working lifetime. The cash benefit changes were found to have a negligible effect on labour supply.

‘Pick me up and not a down down,up up’: how are the identities of people with aphasia represented in aphasia,stroke and disability websites?

Suddenly acquiring a permanent impairment means a person must learn to think differently (Frank, 1995), and he or she does so partly by telling stories. The most commonly told illness narratives are 'restitution' narratives. People with aphasia (a communication impairment commonly following stroke) surfed aphasia, stroke and disability websites, read the personal stories attached to them, and created their own narratives in response. Charitable and disability-related websites excluded people with aphasia through their tone, content and narrative 'voice.' Engagement with some websites was contingent on subscribing to a specific perspective on aphasia. Personal narratives attached to charitable websites were seen to reflect the organisational stance. In particular, idiosyncracies of aphasic language were often eliminated. When participants constructed their own web pages they replicated the stylistic traits that had previously been criticised. Identities are mercurial and difficult to pinpoint. Further work with people with aphasia using videoclips, soundclips and other non-text-based techniques to create illness narratives is planned.
