Dental hygiene students' and recent graduates' intentions, attitudes, and perceptions of academic careers.

PURPOSE: The purpose of this study was to explore dental hygiene students' and recent graduates' awareness, attitudes, perceived barriers, motivators, and intentions to pursue a career in academia as a dental hygiene educator. METHODS: Cross-sectional survey research was conducted with a non-probability sample of dental hygiene students and recent graduates (n = 451). The survey included sections for familiarity regarding academic careers for dental hygienists, attitudes toward academic careers, barriers and motivating factors for this career path, and future academic career intentions. Analysis included descriptive, correlations, and regression. RESULTS: Of 451 surveys started, 296 were at least 80% complete for a completion rate of 66%. The most reported barrier to a career in academia was the cost to obtain the required degree to become an educator (67.6%, n = 200), and for motivating factors was a sense of accomplishment (62.8%, n = 186). Regression analysis of likelihood to pursue a higher education degree showed two main predictors; belief that higher education would advance the dental hygiene profession (ß = 0.35, p < 0.001) and willingness to take a pay cut to become an educator (ß = 0.24, p < 0.001). CONCLUSIONS: Overall dental hygiene students and recent graduates were familiar with and had a positive view of careers in academia. However, barriers included cost and time for obtaining a higher degree, as well as the pay differential between academia and private practice. The educator shortage in dental hygiene may be alleviated by providing educators with loan forgiveness and offering salaries comparable to clinical practice.

Perceptions of Dental Hygienists About Thesis Completion in Graduate Education.

Few studies have been published on thesis completion experiences of master's degree students. However, for doctoral students, dissertation completion has been found to be dependent on individual, relational, and institutional factors. The aim of this study was to examine dental hygienists' perceptions of their experiences completing a thesis as a requirement for an advanced degree. A qualitative phenomenological research design was used utilizing virtual focus groups with a national purposive sample of dental hygienists (n=25) who had graduated from a degree program in which a thesis was a requirement for the degree. Data analysis used an inductive approach to identify themes using Liechty et al.'s framework of individual, relational, and institutional factors impacting completion of a dissertation. Liechty et al.'s framework is based on Vygotsky's sociocultural theory of learning. In the results, individual factors identified included family/work responsibilities, lack of understanding of the thesis process, time management, health issues, and reaching personal and professional goals. Relational factors focused primarily on positive and negative experiences with the thesis advisor/committee and support from expert peers/family. Institutional factors included the thesis structure, financial concerns, and challenges in recruiting research participants. This study found many factors influencing the thesis experience that may help guide the process in graduate degree programs. In addition, the findings suggest a need to provide mentoring and support for thesis advisors and committee members to more effectively guide students through the thesis process. Effective modifications of these may improve retention of students and facilitate timely completion of thesis research.

Self-Perceptions of Value, Barriers, and Motivations for Graduate Education Among Dental Hygienists.

Increasing the knowledge base of its practitioners through formal education is vital to advancing the dental hygiene profession, ensuring practitioners' readiness for participation in future health care workforce models, and preparing future dental hygiene educators. The aim of this study was to discover the value of, barriers to, and motivations for graduate education among dental hygienists as a first step toward establishing ways to stimulate enrollment and facilitate program change. A qualitative pilot study design was used, with focus groups used for data collection. Four virtual focus groups were conducted on a video conferencing platform with dental hygienists (N=15) of varying educational levels residing in nine states. Focus group results were examined for emerging themes. The majority of participants placed a high value on graduate education as it related to expanding employment options and satisfying personal goals, but perceived it to have little value regarding advancement in clinical practice. Top barriers to education were reported to be time management, finances, and degree program options. Motivational themes for pursuing education included increased career options, benefits, and salary; personal satisfaction; potential to advance the profession; and financial support. The participants agreed that increased education can lead to more varied career opportunities and advance the profession, but their responses suggested limited motivation to pursue graduate studies. Determining ways to increase the value, reduce barriers, and enhance motivation for a graduate degree should be a priority of academic institutions and professional organizations involved in dental hygiene to ensure a workforce that is qualified for future health care initiatives and prepared to become educators.

Copepod hatching success in marine ecosystems with high diatom concentrations.

Diatoms dominate spring bloom phytoplankton assemblages in temperate waters and coastal upwelling regions of the global ocean. Copepods usually dominate the zooplankton in these regions and are the prey of many larval fish species. Recent laboratory studies suggest that diatoms may have a deleterious effect on the success of copepod egg hatching. These findings challenge the classical view of marine food-web energy flow from diatoms to fish by means of copepods. Egg mortality is an important factor in copepod population dynamics, thus, if diatoms have a deleterious in situ effect, paradoxically, high diatom abundance could limit secondary production. Therefore, the current understanding of energy transfer from primary production to fisheries in some of the most productive and economically important marine ecosystems may be seriously flawed. Here we present in situ estimates of copepod egg hatching success from twelve globally distributed areas, where diatoms dominate the phytoplankton assemblage. We did not observe a negative relationship between copepod egg hatching success and either diatom biomass or dominance in the microplankton in any of these regions. The classical model for diatom-dominated system remains valid.
