Meanings of lone motherhood within a broader family context

In this paper, the theoretical approach to the concept of lone motherhood is adopted from ‘new’ family sociology where families are understood to be dynamic processes constituted by webs of relationships. I analyse life stories written by lone mothers in order to examine the meanings that they give to their lone motherhood in relation to their larger family context. This approach reveals that, along with the concept ‘family’, the category ‘lone motherhood’ can be questioned. The life stories show that as with all families, the representations of ‘the lone mother family’ vary. Lone motherhood emerges less as a distinct family form and more as an experience coloured by the lone mother's position in a web of family relationships, as well as her place in her broader personal, social and historical context.     

Pricing policies and corporate strategy

In this article, attention is drawn to the importance of pricing in the formulation of corporate strategies. The author compares traditional “cost plus” pricing with market oriented approaches, and argues the case for pricing policies to be given greater emphasis in corporate planning. He examines the role of the corporate planner in developing price strategies for existing products and for new products and recommends the formulation of product strategies based on greater price leverage.     

A Simplified Method of Calculating an Overall Goodness-of-Fit Test for the Cox Proportional Hazards Model

Gronnesby and Borgan (1996) propose an overall goodness-of-fit test for the Cox proportional hazards model. The basis of their test is a grouping of subjects by their estimated risk score. We show that the Gronnesby and Borgan test is algebraically identical to one obtained from adding group indicator variables to the model and testing the hypothesis the coefficients of the group indicator variables are zero via the score test. Thus showing that the test can be calculated using existing software. We demonstrate that the table of observed and estimated expected number of events within each group of the risk score is a useful adjunct to the test to help identify potential problems in fit.     

Examining the Effect of Correctional Programming on Perceptions of Likelihood of Recidivism Among Incarcerated Prisoners

ABSTRACT

For many years, policymakers and criminal justice scholars have debated the impact of correctional programming on recidivism. This debate is currently unresolved. Using data from 1,234 currently incarcerated inmates in a mid-Southern state, this study examines whether inmates who participate in correctional programming while incarcerated are less likely to feel that they will recidivate upon release from prison. The findings from this research suggest that program participation while in prison has little impact on the inmates’ perceived recidivism, although important programming effects may still occur. Policy implications and directions for future research are discussed.     

When the Methodological Shoe is on the Other Foot: African American Interviewer and White Interviewees

Some scholars engaging in the insider/outsider debate have argued that the pairing of researcher and subjects based on racial similarity—i.e., “race matching”—is the most effective means for conducting qualitative research. Although insider/outsider status has been discussed with respect to white researchers' studies of African Americans, I explore the heretofore rarely discussed situation in which an African American is the researcher and whites are the subjects. I argue that insider status with respect to race continues to be based on a presumed connectedness linked to phenotypical characteristics—like skin color or hair texture. Yet, rather than experiencing a solely insider or outsider status, researchers and subjects experience what I call “insider moments” wherein their interests converge and they are able to share in the kinds of interactions that yield important insights. I conclude by evaluating the utility of insider/outsider status in qualitative research.     

Nightlife Girls: Envy,Theatre, and Encounters with Men and Women

This article explores how envy influences affective performance in the service industry. Utilizing the first‐person accounts of 12 women working in one Manhattan bar, it examines how the experiences these women have with male and female customers are differently intersected by expectations for gendered performance. It further explores how envy — as the emotion most prompted in the servers in the face of these expectations — can in response be harnessed as a force for their critical agency. Seeing envy as both an antagonizer and central defence mechanism, the paper goes on to dissect the various strategies employed by the serving women to both adopt the differing embodiments of affective gender performance expected by their male and female customers, and protect themselves from the emotional damage that is risked in adopting such externally dictated subjectivities.     

Improved estimators for the location of double exponential distribution

In this paper, attention is focused on estimation of the location parameter in the double exponential case using a weighted linear combination of the sample median and pairs of order statistics, with symmetric distance to both sides from the sample median. Minimizing with respect to weights and distances we get smaller asymptotic variance in the second order. If the number of pairs is taken as infinite and the distances as null we attain the least asymptotic variance in this class of estimators. The Pitman estimator is also noted. Similarly improved estimators are scanned over their probability of concentration to investigate its bound. Numerical comparison of the estimators is shown.     

Impaired angiogenesis in the aged

The process of angiogenesis, during which new blood vessels are formed, is impaired during aging. This Perspective describes many of the myriad components of the angiogenic response that are altered with age. In addition, the impact of impaired angiogenesis on wound healing, vascular disease, and cancer in the aged is discussed.     

A Cautionary Note on the Use of the Grønnesby and Borgan Goodness-of-Fit Test for the Cox Proportional Hazards Model

Grønnesby and Borgan (1996, Lifetime Data Analysis 2, 315–328) propose an omnibus goodness-of-fit test for the Cox proportional hazards model. The test is based on grouping the subjects by their estimated risk score and comparing the number of observed and a model based estimated number of expected events within each group. We show, using extensive simulations, that even for moderate sample sizes the choice of number of groups is critical for the test to attain the specified size. In light of these results we suggest a grouping strategy under which the test attains the correct size even for small samples. The power of the test statistic seems to be acceptable when compared to other goodness-of-fit tests.
