Investigating a career choice for nursing based on social cognitive career theory

Nursing shortages still exist in the U.S. so it is important to determine factors that influence decisions to pursue nursing as a career. This comparative, correlational research study revealed factors that may contribute to, or deter students from choosing nursing as a career. The purpose of this study was to determine factors that contribute to a career choice for nursing based on the concepts of social cognitive career theory (SCCT), self efficacy, outcome expectations, and personal goals, among senior high school students, final year nursing students, and first year nursing students. Based on the results strategies may be developed to recruit a younger pool of students to the nursing profession and to boost retention efforts among those who already made a career choice in nursing. Data were collected using a three part questionnaire developed by the researcher to obtain demographic information and data about the respondents' self efficacy, outcome expectations, and personal goals with regards to nursing as a career. Point bi-serial correlations were used to determine relationships between the variables. ANOVAs and ANCOVAs were computed to determine differences in self efficacy and outcome expectations, among the three groups. Additional descriptive data determined reasons for and against a choice for nursing as a career. Self efficacy and outcome expectations were significantly correlated to career choice among all three groups. The nursing students had higher self efficacy perceptions than the high school students. There were no significant differences in outcome expectations between the three groups. The main categories identified as reasons for choosing nursing as a career were; (a) caring, (b) career and educational advancement, (c) personal accomplishment, (d) proficiency and love of the medical field. Common categories identified for not choosing nursing as a career were; (a) responsibility, (b) liability, (c) lack of respect, and (d) low salary. Other categories regarding not choosing nursing as a career included; (a) the nursing program and (b) professional (c) alternate career choice options and (d) fear of sickness and death. Findings from this study support the tenets of SCCT and may be used to recruit and retain nurses and develop curricula.

A phenomenological exploration of how West Indian professionals in South Florida perceive their career construction

This phenomenological study explored how West Indian professionals in South Florida perceive their career construction. The study used Savickas’s (2005) theory of career construction as its theoretical framework. Semi-structured interviews were conducted, transcribed, and analyzed for 15 West Indian professionals, who self-identified as West Indians and met all the criteria for this study. Interview data were analyzed using inductive, deductive, and comparative analyses. Five themes emerged from the inductive analysis of the data: (a) vocational influences, (b) adjustment challenges, (c) employment patterns, (d) career mobility patterns, and (d) career success perceptions. The theory of career construction guided the deductive analysis. The deductive analysis revealed that both extrinsic and intrinsic influences were equally influential in shaping the participants’ vocational personalities. The deductive analysis also revealed that the participants used three of the career adaptive dimensions: career concern, control, and confidence. Career concern manifested as planning for the future through educational attainment and performing meaningful work. Career control manifested as continuous learning and maintaining secondary careers. Career confidence manifested as self-efficacy expectations, beliefs about one’s ability to perform a behavior that produces desired outcomes. The participants’ life themes or challenges included navigating their identity, starting over, and adjusting to their environment. The comparative analysis revealed that all five themes from the inductive analysis were evident in each of the three tenets of Savickas’s (2005) career construction theory (i.e., vocational personality, career adaptability, and life themes). Career compromises emerged as coping behavior to facilitate the participants’ social and occupational integration. The findings of this study imply that the participants constructed their sense of self in relation to those around them and that their vocational behaviors tend to mobilize and reinforce a mixture of personality and ability. The findings also imply that the participants’ decision-making style and habitual pattern of decision making, may be embedded in their culturally norms, producing a specific cognitive style. Finally, the findings imply that the participants’ career adaptive dimensions were grounded in their attitudes, beliefs, and competencies and overall self-concept. Recommendations for further research are given.

Surfactant solubilization and subsequent bioavailability of phenanthrene

Contamination of soil, sediment and groundwater by hydrophobic organic compounds (HOCs) is a matter of growing concern because groundwater is a valuable and limited resource, and because such contamination is difficult to address. This investigation involved an experimental evaluation of the addition of several surfactant solutions to aqueous and soil-water systems contaminated with phenanthrene, a selected HOC. The results are presented in terms of: * phenanthrene solubilization achieved through surfactant addition * observed effects of surfactant addition on the mineralization of phenanthrene * estimation of relative toxicities of various surfactants using toxicity assays * literature-reported biodegradability/persistence of selected surfactants * surfactant sorption/precipitation onto soil and its impacts on proposed use of surfactant-amended remediation Surfactants were observed to facilitate the transfer of phenanthrene from the soil-sorbed phase to the aqueous pseudophase, however, surfactant solubilization did not translate into enhanced phenanthrene biodegradation.

Aerodynamic Testing of Variable Message Signs

The increasing nationwide interest in intelligent transportation systems (ITS) and the need for more efficient transportation have led to the expanding use of variable message sign (VMS) technology. VMS panels are substantially heavier than flat panel aluminum signs and have a larger depth (dimension parallel to the direction of traffic). The additional weight and depth can have a significant effect on the aerodynamic forces and inertial loads transmitted to the support structure. The wind induced drag forces and the response of VMS structures is not well understood. Minimum design requirements for VMS structures are contained in the American Association of State Highway Transportation Officials Standard Specification for Structural Support for Highway Signs, Luminaires, and Traffic Signals (AASHTO Specification). However the Specification does not take into account the prismatic geometry of VMS and the complex interaction of the applied aerodynamic forces to the support structure. In view of the lack of code guidance and the limited number research performed so far, targeted experimentation and large scale testing was conducted at the Florida International University (FIU) Wall of Wind (WOW) to provide reliable drag coefficients and investigate the aerodynamic instability of VMS. A comprehensive range of VMS geometries was tested in turbulence representative of the high frequency end of the spectrum in a simulated suburban atmospheric boundary layer. The mean normal, lateral and vertical lift force coefficients, in addition to the twisting moment coefficient and eccentricity ratio, were determined using the measured data for each model. Wind tunnel testing confirmed that drag on a prismatic VMS is smaller than the 1.7 suggested value in the current AASHTO Specification (2013). An alternative to the AASHTO Specification code value is presented in the form of a design matrix. Testing and analysis also indicated that vortex shedding oscillations and galloping instability could be significant for VMS signs with a large depth ratio attached to a structure with a low natural frequency. The effect of corner modification was investigated by testing models with chamfered and rounded corners. Results demonstrated an additional decrease in the drag coefficient but a possible Reynolds number dependency for the rounded corner configuration.
