The socialization of sex-roles and fertility ideals: a study of two generations in Toronto.

A pilot study was conducted in Canada to assess intergenerational change and continuity with regard to sex-roles and fertility ideals. 95 mother-adolescent child pairs in metropolitan Toronto were studied. The pairs were: 1) British-origin Protestant; 2) Italian-origin Catholic; or 3) European-origin Jewish. Agreement between mothers and children on the following 5 areas was measured: 1) sex-role stereotypes; 2) sex-role self-concepts; 3) sex-role standards; 4) parenthood satisfactions; and 5) family size ideals. Mother-son and mother-daughter comparisons were similar. There is no gap between generations in the sex-role stereotype or sex-role self-concept scores. The younger generation was less traditional in their sex-role standards had lower fertility ideals and saw children less often as providing their own role. The most change in these attitudes occurred among children of the more traditional families resulting in a convergence of views among religious groups in the 2nd generation. It is seen that specific socialization experiences within the family rather than demographic variables seem to be more influential in the choice of sex-roles and fertility preference. Children differed most from their mothers in situations where the maternal role model had been viewed as inappropriate.
Prognostic Factors in Patients with Multiple Recurrences of Well-Differentiated Thyroid Carcinoma

Introduction. Patients with multiple recurrences of well-differentiated thyroid carcinoma (WDTC) have markedly reduced overall survival when compared with those who have ≤1 recurrence of their disease. The purpose of this investigation is to identify prognostic factors for mortality in this subgroup. Methods. Patients with multiple recurrences of WDTC were retrospectively identified from the thyroid cancer database at Mount Sinai Hospital, Toronto (1963–2000). Data on patient, tumor, and recurrence characteristics were collected, and each patient was given a MACIS score. Results. A total of 31 patients were identified (11 male, 20 female; 16–83 years). Using univariate analysis, age >45, stage III/IV disease, distant metastasis, vascular invasion, MACIS score >6, and time to recurrence of <12 months were found to be significant predictors for mortality in this subgroup. Conclusions. Patients with multiple recurrences of WDTC follow a distinct clinical course, marked with multiple treatment failures and a substantial risk of mortality.

Robust Selling Mechanisms

We consider the problem of a seller who faces a privately informed buyer and only knows one moment of the distribution from which values are drawn. In face of this uncertainty, the seller maximizes his worst-case expected profits. We show that a robustness property of the optimal mechanism imposes restrictions on the seller’s ex-post profit function. These restrictions are used to derive the optimal mechanism. The optimal mechanism entails distortions at the intensive margin, e.g., except for the highest value buyer, sales will take place with probability strictly smaller than one. The seller can implement such allocation by committing to post prices drawn from a non-degenerate distribution, so that randomizing over prices is an optimal robust selling mechanism. We extend the model to deal with the case in which: (i) M goods are sold and the buyer’s private information is multidimensional and (ii) the seller and the buyer interact for several periods. In the case of multiple goods, there are several optimal mechanisms. With multiple goods full bundling is optimal, as well as selling the goods in a fully separable way. In the dynamic model, we show that repetition, period by period, of the static-optimal mechanism is optimal.
Feeling emotions: A better Moodmeter

The aim of this project is to create a better functioning emotion recognition engine by integrating two existing technologies. One of these technologies is expression recognition based on face tracking. The other technology is using a webcam to measure a users heartrate and other physiological changes without any physical contact. Combining both these concepts should allow for a face detection system that uses both heartrate and facial expressions to determine a persons current emotional state (because often, a persons facial expression alone is not enough to identify how he/she is feeling). The project could prove useful in long term monitoring of the general population, sensing unrest in volatile areas, additional security in airports, etc.
Identification of a 47 kDa fibronectin‐binding protein expressed by Borrelia burgdorferi isolate B31

The attachment of pathogenic microorganisms to host cells and tissues is often mediated through the expression of surface receptors recognizing components of the extracellular matrix (ECM). Here, we investigate the ability of Borrelia spirochaetes to bind the ECM constituent, fibronectin. Borrelia lysates were separated by SDS–PAGE, transferred to nitrocellulose and probed with alkaline phosphatase‐labelled fibronectin (fibronectin‐AP). Five of six Borrelia species and four of eight B. burgdorferi sensu lato isolates expressed one or more fibronectin‐binding proteins. Borrelia burgdorferi isolate B31 expressed a 47 kDa (P47) fibronectin‐binding protein that was localized to the outer envelope based on susceptibility to proteinase K. The interaction of P47 with fibronectin was specific, and the region of fibronectin bound by P47 mapped to the gelatin/collagen binding domain. P47 was purified by affinity chromatography, digested with endoproteinase Lys‐C, and the peptide fragments analysed by liquid chromatography/tandem mass spectroscopy. A search of protein databases disclosed that the P47 peptide mass profile matched that predicted for the bbk32 gene product of B. burgdorferi isolate B31. The bbk32 gene was cloned into Escherichia coli, and the ability of recombinant BBK32 to bind fibronectin and inhibit the attachment of B. burgdorferi was demonstrated. The identification of BBK32 as a receptor for fibronectin binding may enhance our understanding of the pathogenesis and chronic nature of Lyme disease.
Combination Approaches Improve Predictive Performance of Diagnostic Rules for Mass-Spectrometry Proteomic Data

We consider a proteomic mass spectrometry case-control study for the construction of a diagnostic rule for patients' disease status allocation. We propose an approach for combining a collection of classifiers for the construction of a "combined" classification rule in order to enhance calibration and prediction ability. In a first stage this is achieved by building individual classifiers separately, each one using the entire proteomic data set. A double leave-one-out cross-validatory approach is used to estimate the class-predicted probabilities on which the combination method will be calibrated. The performance of the combination approach is examined both through a breast cancer proteomic data set and through simulation studies. Our experimental results indicate that in many circumstances gains in classification performance and predictive accuracy can be achieved.
Feedback Inhibition in the PhoQ/PhoP Signaling System by a Membrane Peptide

The PhoQ/PhoP signaling system responds to low magnesium and the presence of certain cationic antimicrobial peptides. It regulates genes important for growth under these conditions, as well as additional genes important for virulence in many gram-negative pathogens. PhoQ is a sensor kinase that phosphorylates and activates the transcription factor PhoP. Since feedback inhibition is a common theme in stress-response circuits, we hypothesized that some members of the PhoP regulon may play such a role in the PhoQ/PhoP pathway. We therefore screened for PhoP-regulated genes that mediate feedback in this system. We found that deletion of mgrB (yobG), which encodes a 47 amino acid peptide, results in a potent increase in PhoP-regulated transcription. In addition, over-expression of mgrB decreased transcription at both high and low concentrations of magnesium. Localization and bacterial two-hybrid studies suggest that MgrB resides in the inner-membrane and interacts directly with PhoQ. We further show that MgrB homologs from Salmonella typhimurium and Yersinia pestis also repress PhoP-regulated transcription in these organisms. In cell regulatory circuits, feedback has been associated with modulating the induction kinetics and/or the cell-to-cell variability in response to stimulus. Interestingly, we found that elimination of MgrB-mediated feedback did not have a significant effect on the kinetics of reporter protein production and did not decrease the variability in expression among cells. Our results indicate MgrB is a broadly conserved membrane peptide that is a critical mediator of negative feedback in the PhoQ/PhoP circuit. This new regulator may function as a point of control that integrates additional input signals to modulate the activity of this important signaling system.
A Healthy Divide: Subgroups as a Stimulus for Team Learning Behavior

This paper examines the relationship between subgroups and team learning behavior, defined as a cycle of experimentation, reflective communication, and codification. We develop the construct of “subgroup strength,” defined as the degree of overlap across multiple demographic characteristics among a subset of team members. Contrary to conventional wisdom, we propose that the presence of subgroups within a team may stimulate learning behavior and that organizational design features, such as performance management by an external leader, team empowerment, and the availability of a knowledge management system, may have different effects on teams, depending on subgroup strength. Data on 156 teams in five pharmaceutical and medical products firms confirmed that moderately strong demographic subgroups in teams fostered learning behavior. In addition, both very homogeneous and very heterogeneous teams were more inclined to engage in learning behavior, but only if we controlled for the concurrent effect of subgroup strength. Finally, subgroup strength moderated the impact of organizational design features on team learning. Overall, this study contributes to the literature on team composition, design, and learning by highlighting the importance of subgroups for understanding team behavior.
Statistische 3D Formmodellierung mittels quasi-verzerrungsfreier sphärischer Parametrisierung

Kurzfassung. In diesem Beitrag wird die Integration einer etablierten Methode fur die Parametrisierung geschlossener Oberflachen mit minimaler Verzerrung in einen effizienten Algorithmus fur die Erstellung statistischer Formmodelle (SFM) vorgestellt. Dieser bestimmt die erforderlichen Punkt-Korrespondenzen (Landmarken) durch Minimierung der sog. Description Length des SFM. Da diese Optimierung in einer Parameterdomane erfolgt, ist zunachst eine entsprechende Initialisierung in Form von parametrisierten Formreprasentationen erforderlich. Unvermeidbare geometrische Verzerrungen in der Parameterdomane mussen moglichst gering sein, da das resultierende SFM die eigentliche Objektform sonst nur unzureichend reprasentiert. Wahrend vorherige Arbeiten eine Maximierung der Flachentreue der initialen Parametrisierungen oder eine geeignete Umverteilung der Landmarken vornehmen, erlaubt das von uns vorgestellte Verfahren die Minimierung der Flachenverzerrung unter gleichzeitig bestmoglicher Erhaltung der Winkelverhaltnisse.
Coalition formation with uncertain heterogeneous information

Coalition formation methods allow agents to join together and are thus necessary in cases where tasks can only be performed cooperatively by groups. This is the case in the Request For Proposal (RFP) domain, where some requester business agent issues an RFP - a complex task comprised of sub-tasks - and several service provider agents need to join together to address this RFP. In such environments the value of the RFP may be common knowledge, however the costs that an agent incurs for performing a specific sub-task are unknown to other agents. Additionally, time for addressing RFPs is limited. These constraints make it hard to apply traditional coalition formation mechanisms, since those assume complete information, and time constraints are of lesser significance there.To address this problem, we have developed a protocol that enables agents to negotiate and form coalitions, and provide them with simple heuristics for choosing coalition partners. The protocol and the heuristics allow the agents to form coalitions in the face of time constraints and incomplete information. The overall payoff of agents using our heuristics is very close to an experimentally measured optimal value, as our extensive experimental evaluation shows.
ORIENTATIONS TO HAPPINESS AND SUBJECTIVE WELL-BEING AMONG TEACHERS IN SWAZILAND.

Teachers play a pivotal role in the education system and in society at large. With this in mind, the government should address their particular needs. In the context of positive psychology, issues of happiness and subjective well-being could lead to increased educational outcomes and general health. The purpose of the research was to determine the relationship between orientations to happiness and subjective well-being and to determine whether the orientations to happiness hold predictive value for satisfaction with life. A cross-sectional survey design was used for the study. A sample of 175 (N=175) teachers in Swaziland was used. Three demographic questionnaires were used: the Orientations to Happiness Questionnaire (OHS) (Peterson, Park, & Seligman, 2005), Satisfaction With Life Scale (SWLS) (Diener, Emmons, Larsen, & Griffin, 1985) to measure subjective well-being, General Health Questionnaire (GHQ28) (Goldman & Hillier, 1979) as well as a biographical questionnaire. Results indicated that pleasure and engagement (subscales of orientations to happiness) were positively correlated with satisfaction with life. General health subscales, somatic symptoms, anxiety/insomnia, and severe depression had a negative relationship with satisfaction with life. Of the three orientations, pleasure was found to have predictive value for life satisfaction. Implications of the findings on the relationships between orientations and subjective well-being for helping teachers to promote a more satisfying life are discussed.
Teaching Strategies for the Net Generation

To date, more than 30 books and scores of articles and chapters have been written on the Net Generation. They describe their distinguishing characteristics from previous generations and their implications for education, the workplace, and the political, social, and economic arenas. The problem is that is no consensus on those characteristics, the birth dates for defining this population, the names for this generation, and whether it is even possible to identify a clear-cut profile. For the 18-years-old to 20-something group of current undergraduate and graduate students in this cohort, general guidelines for teaching strategies have been proffered by a few educational researchers. The purposes of the article are to furnish a clarification of the issues creating confusion for faculty and administrators and to suggest specific directions for future teaching in this digital culture. It will synthesize the research evidence from 10 major national and international surveys of this generation and the latest thinking on their educational implications. The material is organized into four sections: (1) defining this generation by birth date and name, (2) characteristics of Net Geners, (3) teaching strategies for Net Geners, and (4) epilogue.
From 'Welfarism' to 'New Managerialism': Shifting discourses of school headship in the education marketplace

Education in the UK is now subject to a regime of organisation and funding based on the principles of the market. Although since May 1997 the UK has had a New Labour government formally committed to policies designed to increase democratic accountability, it remains the case that schools effectively function as small businesses, and in areas where the capacity of schools is in excess of student demand, schools are in competition for student recruitment. This market-like environment has implications not only for work practices, organisational methods and social relationships but also for values of schooling, an area almost totally ignored in policy debates and research on quasi-market reforms. This is one of a series of papers in which we are attempting, in various ways, to capture and make sense of the cultural and value changes within secondary schools arising from the marketisation of education provision (Ball, 1997a, 1997b; Gewirtz, 1997, 1999). In this paper we address the question of values by focusing on the shifting discourses of school headship. That is, we want to begin to examine transformations both in the practices of school headship and in the ways that school heads think and talk about their role. Our approach here is to focus on the case of one inner-city comprehensive school, Beatrice Webb. The school is one of four London secondary schools we researched in some depth as part of our study, ‘Schools, Cultures and Values’, funded by the UK Economic and Social Research Council (award no. R000235544), and this paper draws on interview and observational data gathered over a two-year period of  eldwork in the school (from 1994–1996). Beatrice Webb is an interesting case because what happens there, and the way its participants talk about what happens, brings into sharp focus the discursive shift that is evident on a larger scale in the management of the UK public sector as a whole. Within the recent sociological literature on organisational change in education and other welfare sectors this shift has been conceptualised in various ways. Angus (1994) describes a move away from participative/professional forms of administration to technical/managerial ones. Grace (1995) contends that a social democratic phase of school headship has been
Multicast Congestion Control with Distrusted Receivers

Congestion control protocols rely on receivers to support fair bandwidth sharing. However, a receiver has incentives to elicit self-beneÞcial bandwidth allocations and hence may manipulate its congestion control protocol. Whereas the issue of receiver misbehavior has been studied for unicast congestion control, the impact of receiver misbehavior in multicast remains unexplored. In this paper, we examine the problem of fair congestion control in distrusted multicast environments. We classify standard mechanisms for multicast congestion control and determine their potential vulnerabilities to receiver misbehavior. Our evaluation of prominent multicast protocols shows that each of them is susceptible to attacks by a misbehaving receiver.
Recent advances in pestivirus research.

Introduction. The term ‘pestivirus’ was coined in 1973 to group together two antigenically related enveloped RNA viruses: hog cholera virus (HCV) and bovine viral diarrhoea virus (BVDV; Horzinek, 1973). A third animal pathogen, the border disease virus (BDV) of sheep, was found later to be a close relative of BVDV. Pestiviruses are among the smallest enveloped animal RNA viruses (about 40 nm in diameter) and possess a nucleocapsid of non-helical, probably icosahedral symmetry (Horzinek et al., 1967); they share these traits with the numerous flaviviruses, of which the arthropod-borne yellow fever virus is the prototype. The pestiviruses are not arthropod-borne and currently hold generic status in the family Togaviridae. Previously, flaviviruses also held generic status in this family. However, when details of flavivirus molecular structure, replication strategy and gene sequence became known in the early 1980s, the Togaviridae Study Group recognized the fundamental differences and proposed the creation of the new family Flaviviridae with Flavivirus as the only genus (Westaway et al., 1985).
Breast, colorectal, and skin cancer screening practices and family history of cancer in U.S. women.

BACKGROUND Several national medical organizations recommend more intensive screening or screening at an earlier age for individuals with a family history of breast, colorectal, or skin cancer. This study examined whether women with a family history of cancer were more likely to use breast, colorectal, or skin cancer screenings compared with those without such a family history. METHODS The data for this study came from female respondents who participated in the 2000 National Health Interview Survey. The age range of the study subjects and the definitions of cancer screening were determined based on the American Cancer Society recommendations on cancer screening. RESULTS When compared with women without a family history of breast cancer, women with a family history were more likely to undergo a screening mammogram. Women who had a family history of colorectal cancer were twice as likely to use colorectal cancer screening than women without a family history of colorectal cancer. The association of family history with colorectal and breast cancer screening was stronger among the younger age group for which a screening test is recommended if one has such a family history. The association between skin cancer screening and family history of skin cancer was significant only in younger women. CONCLUSIONS Women with a family history of cancer were more likely to have colorectal, breast, and skin cancer screening examinations. This may be a result of more physicians' recommendations and higher personal motivation for getting cancer screening, suggesting that the efficacy of national guidelines has been increasing somewhat.
