as far as bandura’s (1977) conceptualization of the sense of self-efficacy is concerned, it is argued to be context- and even task-specific, compared to other concepts like self-esteem (brown, 2000); therefore, upon the previous research studies, related theories and definitions, and the ideas and views obtained from the interviews conducted with the scholars, the current research study aimed a...
The switch from an out-crossing to a self-fertilizing mating system is one of the most prevalent evolutionary trends in plant reproduction and is thought to have occurred repeatedly in flowering plants. However, little is known about the evolution of self-fertility and the genetic architecture of selfing. Here, we establish Arabidopsis thaliana as a model for genetic analysis of the switch to s...
BACKGROUND We examined fertility-specific distress (FSD) and general distress by type of fertility barrier (FB). METHODS In a random sample telephone survey, 580 US women reported their fertility intentions and histories. Six groups of women were identified: (i) no FBs, (ii) infertile with intent, (iii) infertile without intent, (iv) other fertility problems, (v) miscarriages and (vi) situati...

Premature Ovarian Failure (POF) is cessation of ovarian functions before the age of 40 years with consequent cessation of menstruation. The objective of study was therefore to evaluate the emotional reaction and self-efficacy of women with POF. Forty-two women confirmed to have Premature Ovarian Failure seen at the outpatient clinic of Maternity Hospital fulfilled the study criteria, were enrol...
Women’s affiliative behavior towards kin and responses to facial cues of kinship (self-resemblance) both change as a function of their hormonal status. Such hormone-mediated changes might serve to (1) avoid inbreeding during peak fertility and/or (2) increase kin affiliation during pregnancy. The first hypothesis predicts that responses to kinship cues will be most negative during hormonal stat...
OBJECTIVE To analyze the perceived impact of insurance coverage for fertility medications on patients' fertility treatment decision-making. METHODS We conducted a cross-sectional study involving a patient survey and chart review of women at a Canadian university-affiliated fertility centre. The primary outcome was to determine whether women with self-reported insurance coverage for fertility ...
BACKGROUND Many women throughout the world have history of subfertility (resolved or unresolved), but much remains unknown about services and treatments chosen. METHODS We developed a mixed-mode fertility experiences questionnaire (FEQ) in 2009 through literature review and iterative pilot work to optimize question format and mode of administration. The focus of the FEQ is to collect data ret...
The aim of this study was to compare the fecundity and fertility of B. glabrata and B. straminea by cross- and self-fertilization. To attain this objective, laboratory-raised strains of B. glabrata and B. straminea were used. The former originated from natural breeding grounds in the municipality Paulista, state of Pernambuco, Brazil. The latter originated from irrigation ditches in the municip...
