Understanding vaccine knowledge,attitudes, and decision-making through college student interviews

Abstract

Objective: We aimed to explore knowledge, attitudes, and beliefs about vaccines required for college-entry and vaccine-related behaviors among college students. Participants: Thirty-three full-time undergraduate students, ≥ 18 years old, enrolled at public (2) and private (3) colleges and universities in metropolitan Philadelphia in fall 2016. Methods: We conducted semistructured interviews, which were double-coded with 5,015 comments overall and 99.3% intercoder reliability (κ?=?0.779) using NVivo 11 software. Results: Six key themes emerged: (1) low knowledge about vaccines and requirements; (2) mixed attitudes about required vs. recommended vaccines; (3) high trust in medical professionals; (4) low perceived risk for vaccine-preventable disease outbreaks; (5) substantial parental influence on students’ decision-making; and (6) low utilization of Student Health Services. Conclusions: This study revealed lack of knowledge about and low prioritization of vaccination despite overall positive attitudes towards vaccines. Prematriculation education of college students is critical to increasing vaccine knowledge and use.     

Preventing child sexual abuse: parents' perceptions and practices in urban Nigeria

This study examined parents' perceptions of child sexual abuse as well as prevention practices in an urban community in southwest Nigeria. Questionnaires were collected from 387 parents and caregivers of children younger than 15 years of age. Results showed that many parents felt CSA was a common problem in the community, and most parents disagreed with common child sexual abuse myths. In addition, almost all parents ( >90%) reported communicating with their child(ren) about stranger danger. However, about 47% felt their children could not be abused, and over a quarter (27.1%) often left their children alone and unsupervised. There were no significant variations in the perceptions of child sexual abuse and communication practices. The implications of findings for child sexual abuse prevention are discussed.     

HETEROGENEOUS FIRMS AND THE ORGANIZATION OF PRODUCTION

Firms in the same industry exhibit systematic differences in the organization of production and the structure of employment. Entrepreneurial ability is the specific scarce input that limits the size of a firm. This input must be allocated to two activities, coordinating production and monitoring workers. Able entrepreneurs can convert calendar time into larger supplies of coordinating effort that enable them to assemble large firms. Greater ability implies a higher shadow price of time which increases the implicit costs of monitoring. A dispersion of entrepreneurial abilities generates an equilibrium size distribution of firms. Differences in monitoring costs affect the choice of worker productivities, the design of products, and the organization of production. The monitoring cost hypothesis advanced in this paper goes a long way in explaining the equilibrium of an industry containing heterogeneous firms that differ in size and behavior.

The Log-Normal zero-inflated cure regression model for labor time in an African obstetric population

In obstetrics and gynecology, knowledge about how women''s features are associated with childbirth is important. This leads to establishing guidelines and can help managers to describe the dynamics of pregnant women''s hospital stays. Then, time is a variable of great importance and can be described by survival models. An issue that should be considered in the modeling is the inclusion of women for whom the duration of labor cannot be observed due to fetal death, generating a proportion of times equal to zero. Additionally, another proportion of women''s time may be censored due to some intervention. The aim of this paper was to present the Log-Normal zero-inflated cure regression model and to evaluate likelihood-based parameter estimation by a simulation study. In general, the inference procedures showed a better performance for larger samples and low proportions of zero inflation and cure. To exemplify how this model can be an important tool for investigating the course of the childbirth process, we considered the Better Outcomes in Labor Difficulty project dataset and showed that parity and educational level are associated with the main outcomes.
