Show moreAdvances in geophysical and remote sensing technology, specifically with ground penetrating radar (GPR) and geographic information systems (GIS), have led to increased use for archaeological research within cemeteries. Because of its non-invasive manner and high resolution of subsurface anomalies, GPR is ideal for surveying areas with marked or unmarked graves within cemeteries. Using a GIS assists cemetery research by facilitating integration of datasets and projection of spatial data. What has not been attempted to this point is systematic attempting to correlate detection rates of marked graves using a GPR with the time frame of the grave while incorporating the data within a GIS. This research project is the first to correlate rates of detection with a GPR and the age of marked graves with the data integrated into a GIS platform. Greenwood Cemetery, located in downtown Orlando, FL, was chosen for the study. A total of 1738 graves (ranging in date from 1883-2008) were surveyed with a GPR and then paired with probe data to address whether there is a correlation between rates of detection and age of the surveyed grave. Further, the correlation between the rates of geophysical detection to an independent verification by a T-bar probe and the relationship between the depth and age of the grave by decade were examined. Finally, the problem of collating the relevant survey data was addressed by using a GIS for data integration. The results of the geophysical survey show a correlation between ages of graves and rates of detection. Older graves were detected less with a GPR compared to higher detection rates of more recent graves. The results also support the utility of pairing GPR with probe data for independent verification of findings but show no relationship between ages of grave and depth of burial. Finally, the integration of the survey data to a GIS helps to address the issue of data storage and management, the accuracy of the spatial data, and the ability of the data to be viewed and queried in meaningful ways.

Meeting patient expectations in relation to pain management is an essential component of palliative and end-of-life care. However, previous research has demonstrated that pain is highly prevalent, especially during the four months prior to death. Poorly controlled pain contributes to cognitive failure, depression and an inability to complete daily activities.

Show moreMeeting patient expectations in relation to pain management is an essential component of palliative and end-of-life care. However, previous research has demonstrated that pain is highly prevalent, especially during the four months prior to death. Poorly controlled pain contributes to cognitive failure, depression and an inability to complete daily activities. Unfortunately, pain and symptom management are often inadequate for patients placed in hospice care. The purpose of this study is to evaluate the perspectives of hospice nurses on complementary and alternative therapies to determine if there is an educational need in order to aide in the management of chronic pain in older adults. A survey was developed in order to determine the nursing perceptions of complementary and alternative therapies. A total of 24 participants were recruited. The survey targeted 28 complementary and alternative therapies most commonly used as defined by National Institute for Complementary and Alternative Medicines (NCCAM). Each therapy was ranked on several aspects including perceptions, personal experience, and present knowledge and training. After completing the survey it was found that all participants were either eager or open to use some complementary and alternative therapies in their workplace, in spite of having an educational barrier on how to implement them, and wanted these therapies to become available to patients, families, and staff.

Show moreGround Penetrating Radar (GPR) research conducted in coastal environments is one area that is lacking in archaeology. Surveys conducted in this type of environment afford the opportunity to evaluate the practical use GPR under field conditions. Coastal environments are effective for this evaluation because they offer a host of conditions that GPR surveys do not normally encounter at one time. The relationship of the land to the coast, sub-surface conditions and reliable survey areas create a (")perfect storm(") to test how practical the use of GPR is in coastal environments. This research is a study of homestead cemeteries situated within the boundaries of Cape Canaveral Air Force Station (CCAFS), using GPR. The research has three main goals. The first is to utilize GPR to identify if there are any unknown burials at CCAFS. The second is to test the practical effectiveness of GPR in coastal environments where high water table, geology and saline conditions can limit the capability of the technique to resolve subsurface features. The third is to correlate data from the GPR survey with ethnographic information to enhance the protection and maintenance with what is already available for the cemeteries.Research methods include field-based geophysical data collection in addition to archival and ethnographic historic research. The field component, to which this research pertains, entailed an on-site GPR survey at the nine sites on Cape Canaveral Air Force Station. This was followed by analysis of the information from the survey using standard processing software. Subsequently, a thorough archival search was completed to link historic and ethnographic information with the archaeological data obtained on the cemeteries. The final result of this research was a report that provides a detailed description of the results of the GPR survey of the cemeteries at Cape Canaveral Air Force Station.

Show moreResearch shows that food insecurity rates and experiences vary by subpopulation. This dissertation examines the rates and experience of food insecurity rates across subpopulationsusing a wide variety of sociodemographic factors expanding the current research on de terminants of food insecurity. Subtopics surrounding the current food insecurity research are explored. These topics include determinants of food deserts, SNAP (or food stamps) utilization, and household adaptation strategies. This research shows that current measurements of food insecurity lack the detail needed to understand why households are food insecure besides lacking income. Using Bourdieu's four forms of capital, this study considers factors beyond income tounderstand the determinants of food insecurity. Quantitative analyses utilize nationally representative data from the 2013 Current Population Survey Food Security Supplement, as well as representative food security data collected for Orange County, FL and state of Florida. Qualitative interviews were conducted to examine adaptation strategies of households with children. This research finds that a number of determinants besides income contribute to household food insecurity and encourages policymakers to move beyond income as the major determinant of food insecurity and consider other household and demographic characteristics as equally important to understanding the problem of food insecurity in the US.

Show moreToday's Advance Technology Facilities require low noise levels and increased noise monitoring. Ambient noise can interfere with the accuracy and precision of experiments and manufacturing processes. Therefore preconstruction site surveys are needed to develop strategies for mitigating noise. Vibration and low frequency electromagnetic fields are particularly detrimental for sensitive instruments, and they are also difficult to mitigate. However a large part of these costs can be avoided or minimized if a quiet building site is selected in the first place. Accelerometers and gauss meters combined with a computer for acquisition and analysis provide a low cost method of evaluating noise levels at proposed building sites. This work examines low frequency vibration and electromagnetic fields at two proposed sites for the planned Physical Science Building at the University of Central Florida.

Show moreConsidering the diminishing availability of professional resources, increasing costs, and time requirements involved in early childhood mass screenings, parents are an essential source of information. In this study, the Survey of Speech Development (SSD) (Perry-Carson & Steel, 2001; Steel, 2000) was used to determine the accuracy of parents in reporting the speech sound inventories of their toddlers. Parents of 30 children, who were between the ages of 27 to 33 months old, completed the SSD prior to a speech and language assessment session. Based on assessment results, the children were classified as normal developing or language delayed. A 20-minute play interaction between the parent and child was recorded during the assessment and was transcribed later for analysis. Speech sounds (consonants) were coded as present or absent and comparisons were made between the parents results on the SSD and data from the 20-minute speech sample. A point-by-point reliability analysis of the speech sounds on the SSD compared to those produced in the speech sample revealed an overall parental accuracy of 75%. Further, no differences were found between parent reports and transcribed accounts for total number of different consonants. This was true for parents of both language delayed and language normal toddlers. Results suggest that if given a systematic means of providing information, parents are a reliable source of information regarding sounds their toddlers produce.

Show moreThe current research provides an examination of felony murder to determine the similarities and differences among jurisdictions in the nation. It provides a current analysis of jurisprudence to update the literature as to practices in the United States pertaining to the availability of felony murder and the specific elements that make up the rule. This research conducts a survey of the 50 states, the District of Columbia, and the Federal System. It provides an overview of the felony-murder rule and its availability, the degrees to which the doctrine is utilized, and the subsequent sentences allowable for defendants convicted under the theory. Current statutes are analyzed to establish what circumstances specifically constitute felony murder and the criteria required by each of the jurisdictions. Additionally, it determines to what degree jurisdictions subscribe to the felony-murder theory, which ones allow individuals to be eligible for life sentences or death sentences, and which jurisdictions allow the rule to be applied to non-triggerman offenders.

Show moreA survey was sent to classroom teachers in Central Florida educating students with autism spectrum disorder (ASD) to investigate: 1) intervention practices currently used in the classroom for students with ASD; 2) if the interventions being used are evidence-based, and; 3) if there a difference in use of evidence-based interventions between teachers with the Florida Autism Endorsement and teachers without the Endorsement. A nonprobability purposive study was conducted via an email-based survey. The survey was designed using the tailored design method and was created in Qualtrics.com, an online survey software program. The survey was divided into three major sections: an intervention section which included a variety of evidence and non-evidenced-based practices drawn from the current research literature; a section focused on how teachers select the interventions they use in their classrooms; and, a demographic section. The survey was sent via email to classroom teachers registered with University of Central Florida Center for Autism and Related Disabilities. Participant inclusion criteria included: 1) currently a classroom teacher in a Central Florida, and 2) at least one student with ASD in the classroom. Forty surveys were completed for a ten percent response rate. Results indicated that a variety of evidence- based and non-evidence-based interventions were being used in classrooms. The top three reported interventions were Visual Supports (95 %), Computer Program Applications (93%), and Social Stories (73 %). Based on current empirical evidence, these top three interventions have insufficient evidence regarding their efficacy for use with students with ASD. In addition, two of the interventions reported to be used have a negative evidence base suggesting they may be harmful for some students with ASD. There were no significant differences between teachers with the Florida ASD Endorsement and teachers without the Endorsement with regard to the interventions used. Overall, the results of the study indicated a need for further research to determine which intervention practices may be the most effective for the specific needs of children with ASD.

Show moreGlobalization is the promise of the future, and it presents, quite literally, a world of opportunities not available in the past. International collaborations in science, research, and business now enjoy increased probabilities of success, in part, because of the advance in technology and the possibility of instantaneous communications. The convenience, simplicity and affordability of technology are helping to make the world accessible to almost everyone. With new availability of international concerns and the growth of global partnerships in all areas of interest, an increased need arises for agreements that memorialize collaborators' commitments, responsibilities and obligations. There is a corresponding concern that the agreements be enforceable across national and international lines should anything go wrong. There is no collaboration, partnership or venture that will not be touched in some way by the law. Whose law governs and how rules and regulations of different nations will be applied are of escalating concern. Empirically examining the state of international contract law is the overarching focus of my research. Adopting a research methodology involving both quantitative and qualitative techniques, I am investigating whether any consistency exists between attorneys of different practice sectors (academic, government, corporate and private) considering choice of law, enforcement of contract provisions, and the inclusion of preventative measures of international contracts. My results contribute to the future success of international collaborations of all concerns by empirically identifying the need for increased education on various dispute resolution options, as well as the effect cultural awareness has on the drafting of international contracts.

Show moreThe global burden of disease is staggering in terms of financial costs and human suffering. The general public is aware that physical activity is healthy, although the fact that physical activity can treat and reverse diseases, reduce the risk of cancers, prevent many chronic diseases, stave off cognitive decline, and contribute to quality longevity is less well known. Healthcare practitioners and policymakers are impeded in efforts to support physical activity due to the lack of knowledge of factors associated with physical activity persistence. The purpose of this dissertation was to determine these factors and identify which predict persistent physical activity among veterans to inform future programs and policies to support physical activity for health. The theorized influence of physical activity habit is addressed in the initial dissertation manuscript. Habits being more difficult to lapse from than to continue made them suitable for investigation to address the knowledge gap identified when no reports of long-term physical activity habits were found. Veterans provided an ideal population to study long-term physical activity habits with, as research indicates that veterans likely formed physical activity habits through recurrent physical activity required to meet the fitness requirements of active duty service. This led to the research reported in the second manuscript. The research was based on theory, literature review, and input from veterans. The integrated theory of health behavior change informed the predictor variables investigated. The explanatory and predictive cross-sectional study of community-dwelling veterans used the web survey method to answer questions of which factors were associated with sufficient or insufficient physical activity among veterans, and which factors were predictive. Recruitment of veterans occurred through Amazon's Mechanical Turk (MTurk(&)#174;) and linked veterans to the survey on Qualtrics(&)#174;. Findings revealed direct associations of exercise self-regulation, social support for exercise, and some service-related and other demographic factors with sufficient or insufficient physical activity. Qualtrics(&)#174; allowed for the presentation of survey questions in a variety of formats. To determine the best format for survey items, a state of the knowledge review was conducted. This review is presented in the final dissertation manuscript. Implications for future research, health education, clinical practice, and health policy are identified. It is expected that the knowledge gained in this study will inform future Veterans Affairs programs, provider practices, public health initiatives, and health care policies to support physical activity practices for healthy longevity.

Show moreThere has been an increase in writings that address the last statements of condemned offenders. Many of these writings suggest that exposure to the humanity sometimes exhibited in these last statements may steer public opinion against the death penalty. This dissertation tests this suggestion by exposing 400 participants to randomly generated vignettes containing various capital crimes, demographic characteristics, and last statements. The survey data are analyzed utilizing multilevel modeling. Study results include the effects of varying levels of demonstrated humanity in the last statements of condemned offenders on public opinion, and whether specific demographic characteristics appear to influence study participant responses. Findings showed no statistically significant results that indicate any effect on death penalty opinion as a result of reading last statements demonstrating humanity. Condemned inmates who did not provide a statement, or stated they had nothing to say, elicited higher levels of confidence that executing them was the right thing to do. Condemned inmates who claimed innocence in their last statements were associated with the lowest level of respondent confidence that execution was the right thing to do, and a higher level of support for life without parole as an alternative punishment. Recommendations for further research are discussed.

Show moreHot Mix Asphalt (HMA) overlay is a major rehabilitation treatment for the existing deteriorated pavements (both flexible and rigid pavements). Reflective cracking (RC) is the most common distress type appearing in the HMA overlays which structurally and functionally degrades the whole pavement structure, especially under high traffic volume. Although many studies have been conducted to identify the best performing RC mitigation technique, the level of success varies from premature failure to good performance in the field. In Florida, Asphalt Rubber Membrane Interlayers (ARMIs) have been used as a RC mitigation technique but its field performance has not been successful. In this study, the best performing means to mitigate RC in the overlays considering Florida's special conditions have been investigated. The research methodology includes (1) extensive literature reviews regarding the RC mechanism and introduced mitigation options, (2) nationwide survey for understanding the current practice of RC management in the U.S., and (3) the development of decision trees for the selection of the best performing RC mitigation method. Extensive literature reviews have been conducted to identify current available RC mitigation techniques and the advantages and disadvantages of each technique were compared. Lesson learned from the collected case studies were used as input for the selection of the best performing RC mitigation techniques for Florida's roads. The key input parameters in selecting optimum mitigation techniques are: 1) overlay characterization, 2) existing pavement condition, 3) base and subgrade structural condition, 4) environmental condition and 5) traffic level. In addition, to understand the current practices how reflective cracking is managed in each state, a nationwide survey was conducted by distributing the survey questionnaire (with the emphasis on flexible pavement) to all other highway agencies. Based on the responses, the most successful method of treatment is to increase the thickness of HMA overlay. Crack arresting layer is considered to be in the second place among its users. Lack of cost analysis and low rate of successful practices raise the necessity of conducting more research on this subject.Considering Florida's special conditions (climate, materials, distress type, and geological conditions) and the RC mechanism, two RC mitigation techniques have been proposed: 1) overlay reinforcement (i.e. geosynthetic reinforcement) for the existing flexible pavements and 2) Stress Absorbing Membrane Interlayer (SAMI) for the existing rigid pavements. As the final products of this study, decision trees to select an optimum RC mitigation technique for both flexible and rigid pavements were developed. The decision trees can provide a detailed guideline to pavement engineer how to consider the affecting parameters in the selection of RC mitigation technique.

Show moreAttitudinal research continues to show a more liberal trend in racial attitudes of Whites towards Blacks across a spectrum of issues (i.e. interracial marriage, residential integration, etc.) leading some to believe that we are moving into a post-racial society. However, a growing body of research has brought into question this utopian post-racial assertion. While Whites express support for racial equality in principle, they vehemently oppose race-targeted policies aimed to address racial inequality. This principle-policy gap has been consistently associated with persistent racial resentment; thus, contradicting the notion that of a post-racial era. Existing attitudinal research is often limited to the Black-White binary. Asian Americans in particular are often omitted from attitudinal research. Through a group threat framework, which argues that racial resentment occurs when there exists a threat to valued resources, this dissertation research examines racial attitudes towards Asian American in four domains: education, jobs, marriage, and residential integration. Given the stereotype of the model minority and the successes made by many Asian Americans, the project assesses whether there continues to be underlying racial resentment toward Asian Americans by Whites and whether the racial resentment is based in feelings of threat to valued resources. This study utilized an experimental list survey design, which addresses social desirability bias in traditional survey research. Quantitative analyses were conducted from a sample collected at a large public university. Traditional difference-in-means approach along with Ordinary Least Squares Regression were conducted to examine what factor(s) significantly predicted anger towards Asian Americans in these domains. Results suggests that group threat significantly predicted the presence of anger towards Asian Americans in the job domain, but not in the education, marriage, or residential domains. As group threat increased in the job domain, presence of anger also significantly increased. Results suggest that not every domain stimulates feelings of anger towards Asian Americans. Moreover, not every domain evokes feelings of threat to valued resources.

Show moreThe purpose of this research study is to measure how mothers perceive and use touch with their infants, and its association with maternal resiliency, a measure of coping ability. This is important because the inability to cope causes increased stress, which increases negative perceptions of life events, making it even more difficult to cope. In addition, research has yet to uncover whether or not resiliency is increased in mothers by the same touch and interactions that has been proven to enhance development, attachment, and resiliency in infants. This study involved asking participants (mothers of infants <1 year of age) to complete demographic information and a survey composed of three questionnaires: the Mother-Infant Touch Survey, the Physical Contact Assessment, and the Resilience Scale. Although there were no statistically significant correlations between reported perceptions of touch, mother-infant touch and maternal resiliency, there were a couple of other findings that warrant further investigation. Hispanic mothers scored higher on the Resiliency Scale (RS-14) than Non-Hispanic mothers, and a linear trend was detected between mothers in the < 25 years of age group and higher scores on the RS-14. These findings may influence future research on the correlations between mother-infant touch and maternal coping ability.

The results showed that mathematics anxiety did exist in the classroom, and in-service teachers did report seeing a gender gap between the anxiety experienced by females and males. I believe that from these findings it is important to conduct further research on in-service teachers to see in depth what they think. This is important because their beliefs about the subject can have a lasting impact on their students and their feelings towards mathematics.

Show moreDue to increasing demand on deployable surveillance systems in recent years, object tracking and activity recognition are receiving considerable attention in the research community. This thesis contributes to both the tracking and the activity recognition components of a surveillance system. In particular, for the tracking component, we propose two different approaches for tracking objects in video acquired by mobile cameras, each of which uses a different object shape representation. The first approach tracks the centroids of the objects in Forward Looking Infrared Imagery (FLIR) and is suitable for tracking objects that appear small in airborne video. The second approach tracks the complete contours of the objects, and is suitable for higher level vision problems, such as activity recognition, identification and classification. Using the contours tracked by the contour tracker, we propose a novel representation, called the action sketch, for recognizing human activities.Object Tracking in Airborne Imagery: Images obtained from an airborne vehicle generally appear small and can be represented by geometric shapes such as circle or rectangle. After detecting the object position in the first frame, the proposed object tracker models the intensity and the local standard deviation of the object region defined by the shape model. It then tracks the objects by computing the mean-shift vector that minimizes the distance between the kernel distribution for the hypothesized object and its prior. In cases when the ego-motion of the sensor causes the object to move more than the operational limits of the tracking module, a multi-resolution global motion compensation using the Gabor responses of consecutive frames is performed. The experiments performed on the AMCOM FLIR data set show the robustness of the proposed method, which combines automatic model update and global motion compensation into one framework.Contour Tracker: Contour tracking is performed by evolving an initial contour toward the correct object boundaries based on discriminant analysis, which is formulated as a variational calculus problem. Once the contour is initialized, the method generates an online shape model for the object along with the color and the texture priors for both the object and the background regions. A priori texture and color PDFs of the regions are then fused based on the discrimination properties of the features between the object and the background models. The models are then used to compute the posteriori contour likelihood and the evolution is obtained by the Maximum a Posteriori Estimation process, which updates the contour in the gradient ascent direction of the proposed energy functional. During occlusion, the online shape model is used to complete the missing object region. The proposed energy functional unifies commonly used boundary and region based contour approaches into a single framework through a support region defined around the hypothesized object contour. We tested the robustness of the proposed contour tracker using several real sequences and have verified qualitatively that the contours of the objects are perfectly tracked.Behavior Analysis: We propose a novel approach to represent human actions by modeling the dynamics (motion) and the structure (shape) of the objects in video. Both the motion and the shape are modeled using a compact representation, which is called the ``action sketch''. An action sketch is a view invariant representation obtained by analyzing important changes that occur during the motion of the objects. When an actor performs an action in 3D, the points on the actor generate space-time trajectories in four dimensions $(x,y,z,t)$. Projection of the world to the imaging coordinates converts the space-time trajectories into the spatio-temporal trajectories in three dimensions $(x,y,t)$. A set of spatio-temporal trajectories constitute a 3D volume, which we call an ``action volume''. This volum

Show moreThis study examines the impact of relative deprivation on juvenile delinquency. Though this topic has been explored by several researchers, there has not been much consistency in the research due to the operationalization of key variables. Traditionally, relative deprivation has been referenced in relation to Merton's Classic Strain Theory, using economic indicators to measure relative deprivation. Webber and Runciman however, expanded upon Merton's original premise and integrated more diverse measures of relative deprivation into their research. The current study utilizes Agnew's General Strain Theory (GST) as a means to measure relative deprivation as a broader and more subjective topic. This unique approach in the study of relative deprivation utilizes aspirations as a primary measure of relative deprivation.

Show moreIt has been estimated that one third of the world's population does not have access to "adequate" health care. Some 1.6 billion people live in countries experiencing "concentrated" acquired immune deficiency syndrome (AIDS) epidemics. Many countries in Africa -- and other low-income countries -- are in dire need of help providing adequate health care services to their citizens. They require more hands-on care from Western health workers -- and training so more African health workers can eventually care for their own citizens. But these countries also need assistance acquiring and implementing both texts -- the body of medical information potentially available to them -- and technology -- the means by which that information can be conveyed. This dissertation looks at these issues and others from a multi-faceted approach. It combines a survey of the developers of Web sites designed for use by health workers in low-income countries and a proposal for a novel approach to communication theory, which could help improve health communication and other social marketing practices. It also includes an extensive review of literature regarding a number of topics related to these issues. To improve healthcare services in low-income countries, several things should occur. First, more health workers -- and others -- could visit African countries and other places to provide free, hands-on medical care, as this researcher's group did in Uganda. Such trips are ideal occasions for studying the cultural differences between "mzungu" (white man) and the Ugandan people. A number of useful medical texts have been written for health workers in low-income countries. Others will be published as new health information becomes available. But on what medium will they be published? Computers? Personal digital assistants? During the past 10 years the Internet became an ideal venue for conveying information. Unfortunately, people in target countries such as Uganda encounter cultural differences when such new technologies are diffused. This dissertation looks at cultural and technological difficulties encountered by people in low-income countries who attempt to diffuse information and communication technologies (ICT). Once a technology has been successfully adopted, someone will look for ways to use it to help others. There are hundreds of sites on the Internet -- built by Web developers in Western countries -- that are designed for use by health workers in low-income countries. However, these Web developers also experience cultural and technological differences, based on their knowledge of and attitudes toward best practices in their field. This research includes a survey of Web developers which determined their attitudes toward best practices in their field and tested this researcher's hypothesis that there is no significant difference among the developers' attitudes toward the content on their sites, their audience's cultural needs and the various technological needs their audience has. It was found that the Web developers agree with 17 of 18 perceived best practices and that there is a significant difference between Web developers' attitudes toward their audience's technological needs and their attitudes toward quality content and the audience's cultural needs. Creation of the survey herein resulted in this researcher generating a new way of thinking about communication theory -- called digital research cycles. The survey was based on a review of literature and is rooted in the belief that any successful communication of a computer-mediated message in the information age is a behavior which is influenced by the senders' and receivers' attitudes and knowledge about textual style, the audience, technology and the subject matter to which the message pertains.

Show moreSubcutaneous anticoagulant medications like Heparin and Low-Molecular Weight Heparin are injections that readily cause bruising, pain, induration, and hematoma formation at the injection site. It is known that these adverse reactions can be correlated to the technique used to administer these medications; however, there is no established technique that reduces bruising, pain, induration, and hematoma formation at the site. Currently, the only protocol for subcutaneous Heparin and Low-Molecular Weight Heparin is that it is to be administered subcutaneously in the abdomen and when using a prefilled syringe, the air bubble should not be removed. The purpose of this study was to identify current nursing practice for the administration of these medications and to compare the results to researched techniques that resulted in less adverse site reactions. A total of 33 participants were recruited. The survey targeted six researched techniques found, after a comprehensive literature review, to have reduced site adverse effects associated with subcutaneous Heparin and Low-Molecular Weight Heparin. After completing the survey, it was found that current practice does not reflect techniques researched to reduce bruising, pain, induration, and hematoma formation at the site. In fact, very few completed one of the six research techniques that were questioned, which included: a two minute application of a cold compress/pack before and/or after the injection, an injection duration lasting 30 seconds, slow removal of the needle over five seconds, application of pressure after the injection for a minimum of 30 seconds, use of a hot pack/compress after the injection, and the use of a3 mL syringe. It was also found that there were inconsistencies in techniques that have been previously established as current protocol for these medications.

Show moreCounselors can work at a variety of locations (Vacc & Loesch, 2000). Yet very little is known about each setting (King, 2007) and what type of counselors would have an optimum fit. Burnout is a pervasive issue in counseling (Lawson, 2007) and providing good-fit information could lessen turnover and burnout from the counseling field. The primary purpose of this study included investigating the differences between job satisfaction and value priorities of counselors in private practice and agency settings. The overarching theoretical framework included Frank Parsons' (1909) 'goodness of fit' theory, which is a person-organizational fit theory for job satisfaction. Schwartz Value Theory (Schwartz, 1992, 1994) provided the trait of the person under investigation: value priorities. The use of global and facet measures of job satisfaction provided the 'good-fit' measure (Brief & Weiss, 2002). The final analysis included one hundred and thirty-five counselors, with seventy-two agency counselors and sixty-three private practitioners. Counselors completed two assessments and a survey in a descriptive correlational design. Two methods of group and e-mail administration produced a 98.7 % and 33% response rates, respectively. The data collection instruments included: The Schwartz Value Survey (SVS; Schwartz, 1992), the abridged Job Descriptive Index (aJDI; Stanton et al., 2002), the abridged Job In General Scale (aJIG; Russell et al., 2004), and the Counselor History Questionnaire (Cunningham, 2009). The statistical procedures used to analyze the data included two one-way MANOVAs and four standard multiple regressions. Post- hoc analysis included ANOVA for five subscales on the aJDI measure. The three research questions included; (a) Are there any differences between job satisfaction between counselors in private practice and agency settings? (b) Are there any differences between value priorities of self-transcendence and self-enhancement between counselors in private practice and agency settings?, and (c) Are there any relationships among the variables of job satisfaction and value priorities of counselors in private practice and agency setting? The first research question was supported, with private practitioners reporting statistically significant higher levels of job satisfaction on two measures, with 12.9 % of the variance explained by the model. Furthermore, the results of the post-hoc included private practitioners reporting statistically significant higher ratings on the aJDI subscales of Work and Income, and Agency counselors reporting higher scores on the Supervision subscale. The second and third research questions were not supported; as there were no differences in value priorities of counselors in private practice and agency. Furthermore, no predictive relationships existed among the variables of work location, value priorities, and job satisfaction. The data suggested that private practitioners experienced a higher level of job satisfaction than their counterparts in agency settings. Furthermore, the non-significant results of value priorities suggested that counselors, as a whole, possess similar value priorities which are not altered by different work settings. Implications for counselors and counselor educators were presented, along with areas of future research.
