A descriptive study of factors in the lifestyle of fifty couples married an average of 55.5 years and an average age of seventy-nine years provided data for this report. The non-random sample was heterogeneous using traditional socio-economic indicators. Life-Satisfaction (LSI-Z), Locke-Wallace Marital Adjustment scores, and perception of health were all high. More than half the sample were now or had been sexually active within the past five years. Independence, commitment, companionship and qualities of caring were significant elements in these long-lasting marriages.

Cryptic genetic variation may be an important contributor to heritable traits, but its extent and regulation are not fully understood. Here, we investigate the cryptic genetic variation underlying a Saccharomyces cerevisiae colony phenotype that is typically suppressed in a cross of the lab strain BY4716 (BY) and a derivative of the clinical isolate 322134S (3S). To do this, we comprehensively map the trait's genetic basis in the BYx3S cross in the presence of three different genetic perturbations that enable its expression. This allows us to detect and compare the specific loci harboring cryptic genetic variants that interact with each perturbation. In total, we identify 21 loci, all but one of which interacts with just a subset of the perturbations. Beyond impacting which loci contribute to the trait, the genetic perturbations also influence the extent of additivity, epistasis, and genotype-environment interaction among the detected loci. Additionally, we show that the single locus interacting with all three perturbations corresponds to the coding region of the cell surface gene FLO11. Nearly all of the other loci influence FLO11 transcription in cis or trans. However, the perturbations reveal cryptic genetic variation in different pathways and sub-pathways upstream of FLO11, suggesting that multiple layers of cryptic genetic variation with highly contextual effects underlie the trait. Our work demonstrates an abundance of cryptic genetic variation in transcriptional regulation and illustrates how this cryptic genetic variation complicates efforts to study the relationship between genotype and phenotype.

Background Electronic e-cigarette ever users has been increasing as of 2015, the most prevalent ever users being young adults aged 20-24 years old. The implication of e-cigarette ever user developing into long term users is a emerging public health concern. Methods Electronic cigarette usage frequency and nicotine consumption was measured through a self-administered online survey of young adults (n= 54). Survey was advertised through social media sites between January 2019 till February 2019. Descriptive and inferential statistic was conducted using NCSS 12 to examine the association between electronic cigarette usage and nicotine consumption. Results Among young adults aged 19 to 24 years old, the frequency of e-cigarette usage was 51% high usage, 31% no usage and 16% medium and low usage. For nicotine consumption, respondents were 25% daily, 40% no use, 18% infrequent, and 14.8% frequent. Conclusion There is an association between more frequent electronic cigarette usage and higher nicotine consumption among young adults in British Columbia. Frequency e-cigarette users were found to consumption nicotine at higher frequency then non users. Further research is needed to fully understand the extent of the relationship of if e-cigarette usage promotes daily nicotine consumption or daily nicotine consumption results in higher e-cigarette usage.

AbstractThe present study compared two different types of English-language teaching approaches, the grammatical approach (GA) and the communicative approach (CA), by the cotwin control method. This study has two purposes: to study the effects of teaching approaches and to estimate genetic influences upon learning aptitudes. Seven pairs of identical twins (MZ) and 4 pairs of fraternal twins (DZ) participated in the experiment along with 68 other nontwin fifth graders. Each cotwin was assigned to the GA and CA respectively and received 20 hours of lessons over a 10-day period. The behavioral similarities between MZ cotwins were statistically and descriptively depicted. No major effect of either teaching approach was noted, but the genetic influence upon individual differences of learning achievement was obvious. Furthermore, an interesting interaction between the teaching approaches and intelligence was found, that is, that the GA capitalises on and CA compensates for intelligence. This interactional pattern could be interpreted as an example of genotype-environment interaction. The relationship between genetic factors and learning aptitudes is discussed.

The fecundity of Pacific herring was investigated from a collection of 600 ovaries gathered from various localities along the British Columbia coast during the winter and early spring of 1954–55. It was found that fecundity depended mainly on body length and to a lesser extent on age, independently of its effect on body length. Certain differences in fecundity, found between herring from various localities when die relationship of fecundity to body length was considered, were not found when the relationship between fecundity, body length and age was considered. These differences were attributed to differences in growth rate. Fecundity of herring of same body length and the same age was found to be significantly higher in northern British Columbia than in southern.

This study aims to get the results of the study background of frequent occurrence and out of the employee, the employee's performance has not fulfilled what is expected by the leadership, the study include: (1) competence, motivation and performance of employees, (2) The relationship of competence and motivation, (3) the effect of competence on employee performance, (4) the effect of motivation on employee performance.This type of research is descriptive and verification. The population is Sinarmas Bank branch employees Cirebon. The number of samples taken as many as 215 samples are taken with the withdrawal of a random sample method. Model the effect of using Structurall Equation Modeling (SEM) with LISREL 8.80. The results of this study have suitability in explaining linkages between variables. the results showed that: Competence, motivation and performance of employees are in the good category. Competence and motivation are intimately connected, competencies influence on employee performance, and motivation influence on employee performance.

Child protection practitioners view Aboriginal communities as victim, adversary, participant, partner, and protector of children. These representations of communities are derived from interview data with 19 Aboriginal and non-Aboriginal child protection social workers in British Columbia, Canada. The representations of the community are informed by the practitioner’s geographic relationship to the community and the length of community residency (including whether it’s the practitioner’s community of origin). Practitioners view communities as a victim or adversary when no relationship of trust exists with the community. Practitioners view communities having a participative or partnership role in child protection when trust has developed. When communities take full responsibility for children’s welfare, practitioners view the community as the protector of children. No clear association was found between the different representations of the community and the practitioner’s culture or organizational auspices. The practitioner’s own vision of practice is believed to significantly influence the relationship that develops with the community.

AbstractThe relationship of western spruce budworm outbreaks and population collapse to weather parameters was examined using long term weather records from two stations in the budworm outbreak area of British Columbia and outbreak patterns obtained from Forest Insect and Disease Survey records and from tree stem analyses.Outbreaks were associated with warm dry summers in conjunction with synchrony of larval emergence and bud flush. Collapse of the last two outbreaks was clearly associated with extreme high temperatures following moth flight. Collapse of the earlier outbreaks may have been due to asynchrony between larval emergence and bud flush.

This chapter recounts recent experiences of the author with the University of British Columbia (UBC), its Faculty Association (FA), this association's relationship with the author's campus administration at UBC Okanagan campus (UBCO), and the relationship of the campus administration with the senate of the campus. The chapter is a case study of academic mobbing. The author's targeting, exclusion, and ostracism is fully documented in the chapter and fully explained by the concepts of academic bullying, harassment, and mobbing. It is a case study of where an elected union representative of faculty members and an elected senator was targeted, excluded, and ostracized by the powers that be in the union and university administration, working in collusion and complicity.
