Caught in the Middle? Occupancy in Multiple Roles and Help to Parents in a National Probability Sample of Canadian Adults

This paper considers for a Canadian national probability sample of middle-aged women and men the question of how typical is the experience of being "caught in the middle" between being the adult child of elderly parents and other roles. Three roles are examined: adult child, employed worker, and parent (and a refinement of the parent role, being a parent of a co-resident child). Occupancy in multiple roles is examined, followed by an investigation of the extent to which adults in various role combinations actually assist older parents and whether those who provide frequent help are also those "sandwiched" by competing ommitments. The majority of middle-aged children do not provide frequent help to parents. Notably, the highest proportion of daughters who assist elderly parents are those in their fifties whose children are no longer co-resident. For both sons and daughters, being "caught in the middle" is far from a typical experience in this cross-sectional analysis.multiple roles

Women, Work and Caregiving: How Much Difference Does a Great Job Really Make?

This paper examines whether type of job makes a difference in (a) the likelihood that individuals are providing assistance to elderly relatives, (b) the 'costs' associated with this provision, in terms of both job-related and personal costs, and (c) whether observed relationships differ for men and for women. Data are derived from a sample of Canadian employees who participated in a study of work/family balance conducted by the Work and Eldercare Research Group of CARNET: The Canadian Aging Research Network, based at the University of Guelph. The analysis compared full-time employees in three job categories: managerial/professional (n = 1,996); semi-professional (n = 1,270) and clerical, sales, service, craft and trades (n = 2,112). The data indicate no differences between the three occupational groups in the likelihood of providing assistance to elderly relatives. The relationship between job type and both job and personal costs was found to vary in relation to the extent of involvement in the caregiver role. Job costs include lateness, absenteeism, foregoing promotions, missed meetings, and so forth, while personal costs include the perception of work interference with family life, and perceived levels of stress. Among employees providing between 1 and 4 hours of assistance on average per week, gender is associated with significant differences in job and personal costs. This is not true for those providing more hours of care. For both men and women, there appears to be a threshold (5 or more hours of care on average per week) beyond which neither gender nor job type makes a difference in terms of job and personal costs.caregiving; job costs

Age-Gapped and Age-Condensed Lineages: Patterns of Intergenerational Age Structure among Canadian Families

This paper examines intergenerational connections within Canadian families. Its focus is on intergenerational age structure, the interval or 'gap' in years that separates one generation from the next. Intergenerational age structure is measured in terms of the age of a mother at the birth of her first child. Using data from the 1995 General Social Survey of Canada, the study examines the socio-demographic characteristics of women (n=404) in three- and four-generation families (lineages) that are age-condensed (small age distances between generations that are the result of early fertility) and those that are age- gapped (with large age distances between generations that are the result of late fertility patterns). Across two generations of women, there is a striking similarity in the distributions of age at first birth with just under one-third of the sample having early fertility, just over one-half falling into a normative or "on-time" category, and one-seventh having delayed fertility. However, when matched pairs of mothers and daughters are compared across generations, age-condensed and age-gapped lineage patterns show considerable variability. Although just under one-half of mother-daughter dyads show lineage consistency in family age structure across three generations (most typically in age-condensed/age-condensed or normative/normative age structures), low percentages of women whose family of origin was age-gapped repeat that age structure pattern in their own families of procreation. Socio-demographic factors such as mother's and daughter's age, family size, age at first marriage, and level of education are associated with lineage continuity and discontinuity in family age structure.intergenerational age structure; GSS

WHAT NOW? WHAT NEXT? A NARRATIVE ANALYSIS OF CROSS-CULTURAL ADAPTATION AND COLLEGE STUDENT RETENTION

First year college student retention is important to colleges and universities nationwide (Bean, 2005). Most of the research on retention focuses on self-report data collected from students after they withdraw from the institution. The present study focuses, instead, on student stories about school, as well as at and about “home” during their first semester. The experiences of students who transition from high school to college are sometimes likened to those of individuals who enter a new culture for the first time. Thus, this dissertation is grounded in cross-cultural adaptation theory (Kim, 1988, 2001), which posits that successful adaptation occurs via a stress-adaption-growth dynamic and a gradual process of acculturation toward the new environment and simultaneous deculturation from the previous environment. Stories—in the form of in-class free writing assignments—were collected from 264 first-year college students three times during their first semester. These assignments were designed to capture students’ perceptions about their experiences and interactions at school, as well as their experiences and messages to, from, and about “home” as they evolved over the course of the semester. A thematic analysis revealed the majority of stories about events at school were negative and an overwhelming majority of the stories about events at home were positive. A longitudinal comparative analysis revealed no decrease in the percentage of negative stories about experiences and interactions at or about school. Moreover, stories focused on positive school related experiences decreased over time while stories about positive experiences at or about home gradually increased over the course of the semester. For students who did not enroll for spring semester, the results were similar but more dramatic. A large percentage of non-returners were female, about half were first generation college students, and a majority reported “home” as less than 100 miles from the university. More research ought to focus on what goes on during a student’s first year of college to better understand reasons for withdrawing. In doing so, college and university professionals will be able to work more effectively with high school officials, parents, and students to achieve success once they graduate from high school

A comparison of theoretical line intensity ratios for Ni XII with extreme ultraviolet observations from the JET tokamak

Recent R-matrix calculations of electron impact excitation rates in Ni XII are used to derive the emission line ratios R1 = I (154.17 Å)/I (152.15 Å), R2 = I (152.95 Å)/I (152.15 Å) and R3 = I (160.55 Å)/I (152.15 Å). This is the first time (to our knowledge) that theoretical emission line ratios have been calculated for this ion. The ratios are found to be insensitive to changes in the adopted electron density (Ne) when Ne >= 5 × 10^11 cm−3, typical of laboratory plasmas. However, they do vary with electron temperature (Te), with for example R1 and R3 changing by factors of 1.3 and 1.8, respectively, between Te = 10^5 and 10^6 K. A comparison of the theoretical line ratios with measurements from the Joint European Torus (JET) tokamak reveals very good agreement between theory and observation for R1, with an average discrepancy of only 7%. Agreement between the calculated and experimental ratios for R2 and R3 is less satisfactory, with average differences of 30 and 33%, respectively. These probably arise from errors in the JET instrument calibration curve. However, the discrepancies are smaller than the uncertainties in the R2 and R3 measurements. Our results, in particular for R1, provide experimental support for the accuracy of the Ni XII line ratio calculations, and hence for the atomic data adopted in their derivation

Using found poetry to explore creativity in the professional lives of English teachers

This is an Accepted Manuscript of an article published by Taylor & Francis in Teachers and Teaching: Theory and Practice on 26/04/2023, available online: https://doi.org/10.1080/13540602.2023.2201422This arts-based research considers creativity in the professional lives of English teachers in a school in England within the context of a progressively performative education system. In addition, it explores how found poetry can represent participants' voices in an illuminating and authentic manner. The teachers who participated in the study were able to scrutinise, reflect and comment upon the content of poems created from the words found in an initial interview transcript. This recursive process supports a credible way of seeing and knowing the teachers’ voices in a representation that gives a deeper understanding of the participants' creative experiences. The construction, interrogation, and presentation of the found poems reveal that the teachers of English believe they have reduced freedom to be creative or to act with agency in their professional lives. The reduced freedom to be creative stems from the normalising practices of working within a culture of performance. The restrictions are both tangible and self-imposed by the participants

Aircraft Anomaly Detection Using Performance Models Trained on Fleet Data

This paper describes an application of data mining technology called Distributed Fleet Monitoring (DFM) to Flight Operational Quality Assurance (FOQA) data collected from a fleet of commercial aircraft. DFM transforms the data into aircraft performance models, flight-to-flight trends, and individual flight anomalies by fitting a multi-level regression model to the data. The model represents aircraft flight performance and takes into account fixed effects: flight-to-flight and vehicle-to-vehicle variability. The regression parameters include aerodynamic coefficients and other aircraft performance parameters that are usually identified by aircraft manufacturers in flight tests. Using DFM, the multi-terabyte FOQA data set with half-million flights was processed in a few hours. The anomalies found include wrong values of competed variables, (e.g., aircraft weight), sensor failures and baises, failures, biases, and trends in flight actuators. These anomalies were missed by the existing airline monitoring of FOQA data exceedances

Estimating the potential impact of canine distemper virus on the Amur tiger population (Panthera tigris altaica) in Russia

Lethal infections with canine distemper virus (CDV) have recently been diagnosed in Amur tigers (Panthera tigris altaica), but long-term implications for the population are unknown. This study evaluates the potential impact of CDV on a key tiger population in Sikhote-Alin Biosphere Zapovednik (SABZ), and assesses how CDV might influence the extinction potential of other tiger populations of varying sizes. An individual-based stochastic, SIRD (susceptible-infected-recovered/dead) model was used to simulate infection through predation of infected domestic dogs, and/or wild carnivores, and direct tiger-to-tiger transmission. CDV prevalence and effective contact based on published and observed data was used to define plausible low- and high-risk infection scenarios. CDV infection increased the 50-year extinction probability of tigers in SABZ by 6.3% to 55.8% compared to a control population, depending on risk scenario. The most significant factors influencing model outcome were virus prevalence in the reservoir population(s) and its effective contact rate with tigers. Adjustment of the mortality rate had a proportional impact, while inclusion of epizootic infection waves had negligible additional impact. Small populations were found to be disproportionately vulnerable to extinction through CDV infection. The 50-year extinction risk in populations consisting of 25 individuals was 1.65 times greater when CDV was present than that of control populations. The effects of density dependence do not protect an endangered population from the impacts of a multi-host pathogen, such as CDV, where they coexist with an abundant reservoir presenting a persistent threat. Awareness of CDV is a critical component of a successful tiger conservation management policy
