Combating Childhood Obesity In California, Janelle Borelli

Social Sciences

Childhood obesity has become a major problem in Corporate America. Our youth’s health is at risk, the statistics are alarming, and childhood obesity is largely preventable. In order to solve the childhood obesity epidemic, government action, both state and federal, needs to be taken by passing nutrition standard laws. Also, the built environment should support an active lifestyle rather than one based on fast food and lack of exercise. Families should adopt a healthy lifestyle including having adequate fruits and vegetables at home along with exercising daily.

The Differentiated Impact Of Bridging And Bonding Social Capital On Economic Well-Being: An Individual Level Perspective, Saijun Zhang, Steven. G. Anderson, Min Zhan

The Journal of Sociology & Social Welfare

Social capital refers to trust, norms, and social networks. One of the most important features of social capital is its claimed capacity of promoting economic well-being. Theorists have assumed that any such effects vary according to the nature of different types of social capital. Using longitudinal data from a nationally representative dataset, this study investigates the differentiated effects of individual bonding and bridging social capital on subsequent personal income and income-to-needs ratios. The analyses demonstrate that bridging capital, indicated by involvement in various voluntary organizations, has small but significant effects on future economic wellbeing. However, bonding capital, indicated by connections …

Improving Function In Age-Related Macular Degeneration: Design And Methods Of A Randomized Clinical Trial., Barry W Rovner, Robin J Casten, Mark T Hegel, Robert W Massof, Benjamin E Leiby, William S Tasman

Department of Psychiatry and Human Behavior Faculty Papers

Age-Related Macular Degeneration (AMD) is the leading cause of severe vision loss in older adults and impairs the ability to read, drive, and live independently and increases the risk for depression, falls, and earlier mortality. Although new medical treatments have improved AMD's prognosis, vision-related disability remains a major public health problem. Improving Function in AMD (IF-AMD) is a two-group randomized, parallel design, controlled clinical trial that compares the efficacy of Problem-Solving Therapy (PST) with Supportive Therapy (ST) (an attention control treatment) to improve vision function in 240 patients with AMD. PST and ST therapists deliver 6 one-hour respective treatment sessions …

Research To Practice: The Influential Role Of The Job Developer: Increasing Self-Determination And Family Involvement During The Job Search, Jaimie Ciulla Timmons, Ashley Wolfe

Research to Practice Series, Institute for Community Inclusion

Job developers can influence decision-making during the job search and placement process. For a study exploring the employment decisions of people with intellectual and/or developmental disabilities (IDD), researchers interviewed 16 individuals with IDD, their family members, and professionals involved in their job search. Participants were asked what factors, circumstances, or people affected their decisions about work. The job developer was consistently named the most influential person in the job-search process.

Policy And Practice: An Analysis Of The Implementation Of Supported Employment In Nebraska, Heng-Hsian N. Liu

Department of Psychology: Dissertations, Theses, and Student Research

Supported employment (SE) is an evidence-based practice (EBP) for persons with severe mental illness (SMI) aimed at competitive employment. SE has a large evidence base, demonstrating outcomes across settings and populations. SE has been promoted by the Centers for Medicare and Medicaid Services (in the U.S. Department of Health and Human Services) and widely disseminated through the internet via a “community tool-kit” sponsored by the Substance Abuse and Mental Health Services Administration.

The SE literature expresses the opinion that state governments can successfully implement SE. Researchers have developed implementation guidelines and identified stages of statewide implementation; however, most SE implementation …

Organs Watch: Possibilities And Perils For Public Anthropology, Roberto Abadie

Department of Sociology: Faculty Publications

Recent technological advances in biomedicine have introduced new therapeutic possibilities but have also contributed to the emergence of a global market for human bodies and body parts. For example, artificial modes of human reproduction created a market for eggs, semen, and surrogate wombs. In addition, organ transfer generated a demand for kidneys and half livers. The whole body has become a valuable commodity as professional research subjects venture into the economy of Phase I Clinical Trials, testing drug safety for pharmaceutical companies. In the process, the trade has become a deeply unequal one in which poor, vulnerable, and easily exploited …

Critical Race Theory As Theoretical Framework And Analysis Tool For Population Health Research, Louis Graham, Shelly Brown-Jeffy, Robert Aronson, Charles Stephens

Louis F Graham

In population health research, it is important to consider socioecological perspectives that include cultural attitudes and beliefs which permeate all levels (intrapersonal, interpersonal, institutional/community, and structural/ policy). Given the specificity of target populations centered on identity – ethnic and others – it is appropriate and warranted to centralize cultural studies theories into health determinant investigations. Cultural studies, which focus explicitly on identity exploration and impacts, have much to contribute to health research. In accordance with the transdisciplinary nature of population health and bearing in mind the significant role of ethnic identity in health outcomes, it is beneficial to utilize critical …

Juror Perceptions Of Juveniles Transferred To Criminal Court: The Role Of Generic Prejudice And Emotion In Determinations Of Guilt, Megan Beringer Jones

Department of Psychology: Dissertations, Theses, and Student Research

Research examining juror perceptions of juveniles tried as adults has provided mixed results, with some studies providing evidence of bias against juveniles tried as adults, and others finding no evidence of this bias. The present research aimed to clarify this issue by examining the roles of generic prejudice and emotion in jurors’ judgments of juveniles tried as adults. Study 1 assessed which stereotypes people associate with juveniles tried as adults compared to juveniles tried in juvenile court and adults tried in criminal court. Study 2 examined to what extent angry, fearful, sad, and neutral mock jurors used these stereotypes to …

Prevalence Of Herpes Simplex Virus 1 And 2 In A Sexually Transmitted Disease Clinic In Miami, Maya Morrison-Bryant, Maria Alcaide, Khaled Deeb, Jose G. Castro

Florida Public Health Review

The Prevalence of HSV-1 and HSV-2 among STD clinics in Miami is not known. The objective of this study was to evaluate infection rates of HSV 1 and 2, and to describe the socio-demographic characteristics, sexual orientation and co-infection with HIV and other STIs, in individuals attending a Sexually Transmitted Diseases (STD) clinic in Miami. A cross-sectional study of 663 patients tested for HSV type-specific serology or herpes culture during the year 2007 was performed. An overall infection rate of HSV-1 was 42.1% and 36.7% for HSV-2. Statistically higher infection rates for HSV-1and 2 were seen among Hispanics (56.7%, 54.4%) …

Who Are The Health Center Patients Who Risk Losing Care Under The House Of Representatives' Proposed Fy 2011 Spending Reductions?, Sara J. Rosenbaum, Peter Shin, Leighton C. Ku

Geiger Gibson/RCHN Community Health Foundation Research Collaborative

On February 20, 2011, the United States House of Representatives approved more than $61 billion in discretionary spending reductions for the remainder of FY 2011. The legislation includes $1.3 billion in direct spending cuts for community health centers. Using the NACHC patient estimates, we present evidence on the characteristics of patients whose continuing access to health center services is at risk. We arrived at these estimates using data from the Uniform Data System (UDS), the federal reporting system in which all health centers must participate, as well as national estimates from the Medical Expenditure Panel Survey (MEPS), and published reports …

An Update On Red Light Camera Research: The Need For Federal Standards In The Interest Of Public Safety, Barbara Langland-Orban, John T. Large, Etienne E. Pracht

Florida Public Health Review

Since publishing our critique of red light camera (RLC) studies in 2008, we have gained increased insights on the controversy over RLCs. Herein we provide additional information on RLCs, and use a question-and-answer format to address frequently asked questions. This update includes the rationale given for ignoring fatalities at RLC sites, the convergence in findings from the National Highway Traffic Safety Administration's compendium of best RLC studies, common violations of research methods in RLC evaluations, the RLC cost-to-benefit implications for motorists, an explanation for the increase in rear-end crashes at RLC sites, and why RLCs may be ineffective in reducing …

Decreasing Unwanted Pregnancies By Increasing Use Of Emergency Contraceptive Pills (Ecps): A Leadership Approach, Kara Mcginnis

Florida Public Health Review

Unwanted pregnancies burden the U.S. healthcare system, as well as create challenges for women, families, and children. Emergency contraceptive pills (ECPs) can prevent a large percentage of unwanted pregnancies if used appropriately. Factors contributing to non-use of ECPs include the negative social environment created by views on sexual health, misunderstanding concerning the mechanism ofaction, women’s misperceptions oftheir risks ofgetting pregnant and how ECPs work, barriers to obtaining ECPs, and lack of counseling about ECPs from healthcare providers. Leadership is needed to address these factors contributing to the problem. Health educators are in a unique position to lead the field in …

Phonemic Resetting Versus Postural Adjustments In The Speech Of Cochlear Implant Users: An Exploration Of Voice-Onset Time, Harlan Lane, Jane Wozniak, Melanie Matthies, Mario Svirsky, Joseph Perkell

Harlan Lane

Voice-onset time (VOT) was measured in plosive-initial syllables uttered by five cochlear implant users prior to and repeatedly at intervals after activation of their speech processors. In "short-term" experiments, the elicitation set was read after the subject's processor had been off for 24 h, then turned on, then off again. Four out of five implant users increased voiceless and/or voiced VOTc (VOT corrected for changes in syllable duration) from preimplant baselines to final recordings made 1–3 years later. Measured acoustic correlates of speech "posture" (average SPL, F0, and low-frequency spectral slope) changed concurrently. Results in the short-term study were largely …

Changes In Sound Pressure And Fundamental Frequency Contours Following Changes In Hearing Status, Harlan Lane, Jane Wozniak, Melanie Matthies, Mario Svirsky, Joseph Perkell, Michael O'Connell, Joyce Manzella

Harlan Lane

Sound-pressure level (SPL) and fundamental frequency (F0) contours were obtained from four postlingually deafened adults who received cochlear implants and from a subject with Neurofibromatosis-2 (NF2) who had her hearing severely reduced following surgery to remove an auditory-nerve tumor and to implant an auditory brainstem implant. SPL and F0 contours for each phrase in passages read before and after changes in hearing were averaged over repeated readings and then normalized with respect to the highest SPL or F0 value in the contour. The regularity of each average contour was measured by calculating differences between successive syllable means and averaging the …

Effects Of Bite Blocks And Hearing Status On Vowel Production, Harlan Lane, Margaret Denny, Frank Guenther, Melanie Matthies, Lucie Ménard, Joseph Perkell, Ellen Stockmann, Mark Tiede, Jennell Vick, Majid Zandipour

Harlan Lane

This study explores the effects of hearing status and bite blocks on vowel production. Normal-hearing controls and postlingually deaf adults read elicitation lists of /hVd/ syllables with and without bite blocks and auditory feedback. Deaf participants' auditory feedback was provided by a cochlear prosthesis and interrupted by switching off their implant microphones. Recording sessions were held before prosthesis was provided and one month and one year after. Long-term absence of auditory feedback was associated with heightened dispersion of vowel tokens, which was inflated further by inserting bite blocks. The restoration of some hearing with prosthesis reduced dispersion. Deaf speakers' vowel …

An Investigation Of The Relation Between Sibilant Production And Somatosensory And Auditory Acuity, Satrajit Ghosh, Melanie Matthies, Edwin Maas, Mark Tiede, Lucie Ménard, Frank Guenther, Harlan Lane, Joseph Perkell

Harlan Lane

The relation between auditory acuity, somatosensory acuity and the magnitude of produced sibilant contrast was investigated with data from 18 participants. To measure auditory acuity, stimuli from a synthetic sibilant continuum ([s]-[ʃ]) were used in a four-interval, two-alternative forced choice adaptive-staircase discrimination task. To measure somatosensory acuity, small plastic domes with grooves of different spacing were pressed against each participant's tongue tip and the participant was asked to identify one of four possible orientations of the grooves. Sibilant contrast magnitudes were estimated from productions of the words "said," "shed," "sid," and "shid." Multiple linear regression revealed a significant relation indicating …

Economy Of Effort In Different Speaking Conditions. I. A Preliminary Study Of Intersubject Differences And Modeling Issues, Joseph S. Perkell, Majid Zandipour, Melanie L. Matthies, Harlan Lane

Harlan Lane

This study explores the hypothesis that clear speech is produced with greater "articulatory effort" than normal speech. Kinematic and acoustic data were gathered from seven subjects as they pronounced multiple repetitions of utterances in different speaking conditions, including normal, fast, clear, and slow. Data were analyzed within a framework based on a dynamical model of single-axis frictionless movements, in which peak movement speed is used as a relative measure of articulatory effort (Nelson, 1983). There were differences in peak movement speed, distance and duration among the conditions and among the speakers. Three speakers produced the "clear" condition utterances with movements …

Effects Of Masking Noise On Vowel And Sibilant Contrasts In Normal-Hearing Speakers And Postlingually Deafened Cochlear Implant Users, Joseph Perkell, Margaret Denny, Harlan Lane, Frank Guenther, Melanie Matthies, Mark Tiede, Jennell Vick, Majid Zandipour, Ellen Burton

Harlan Lane

The role of auditory feedback in speech production was investigated by examining speakers' phonemic contrasts produced under increases in the noise to signal ratio (N/S). Seven cochlear implant users and seven normal-hearing controls pronounced utterances containing the vowels /i/, /u/, /ε/ and /æ/ and the sibilants /s/ and /ʃ/ while hearing their speech mixed with noise at seven equally spaced levels between their thresholds of detection and discomfort. Speakers' average vowel duration and SPL generally rose with increasing N/S. Average vowel contrast was initially flat or rising; at higher N/S levels, it fell. A contrast increase is interpreted as reflecting …

Note On The Variability Hypothesis In Category Scaling, B. Schneider, H. Lane

Harlan Lane

The "variability hypothesis" attributes the nonlinear relation between category and magnitude scales to the growth of variability along the psychological continuum. The findings of some earlier research seemed to contradict the hypothesis. Now, an alternative interpretation of these findings is presented.

Speech Of Cochlear Implant Patients: A Longitudinal Study Of Vowel Production, Joseph Perkell, Harlan Lane, Mario Svirsky, Jane Webster

Harlan Lane

Acoustic parameters were measured for vowels spoken in /hVd/ context by four postlingually deafened recipients of multichannel (Ineraid) cochlear implants. Three of the subjects became totally deaf in adulthood after varying periods of partial hearing loss; the fourth became totally deaf at age four. The subjects received different degrees of perceptual benefit from the prosthesis. Recordings were made before, and at intervals following speech processor activation. The measured parameters included F1, F2, F0, SPL, duration, and amplitude difference between the first two harmonic peaks in the log magnitude spectrum (H1–H2). Numerous changes in parameter values were observed from pre- to …

A Preliminary Study Of The Effects Of Cochlear Implants On The Production Of Sibilants, Melanie L. Matthies, Mario A. Svirsky, Harlan L. Lane, Joseph S. Perkell

Harlan Lane

The potential influence of auditory information in the production of /s/ and /ʃ/ was explored for postlingually deafened adults with four-channel Ineraid cochlear implants. Analyses of the spectra of the sibilant sounds were compared for speech obtained prior to implant activation, after early implant use and after 6 months of use. In addition, the output of the Ineraid device (measured at each of the four electrodes) was analyzed with pre- and postactivation speech samples to explore whether the speech production changes were potentially audible to the cochlear-implant user. Results indicated that subjects who showed abnormally low or incorrect contrast between …

Speech Deterioration In Postlingually Deafened Adults, Harlan Lane, Jane Webster

Harlan Lane

Postlingually deafened adults reading the Rainbow Passage differed from hearing-control subjects in producing greater pitch variability and mean pitch on stressed and unstressed vowels, greater fluctuations in pitch within sentences, less correlation of intrinsic pitch with vowel height and slower temporal parameters. When reading the Phonetic Inventory Sentences, they revealed less differentiation of place of articulation in fricative and plosive consonants. The present findings, taken together with those of longitudinal and implant studies, are applied to constraining models of the role of self hearing in the elaboration of speech.

Ratio Scales, Category Scales, And Variability In The Production Of Loudness And Softness, Bruce Schneider, Harlan Lane

Harlan Lane

Several studies have shown that category scales are nonlinearly related to ratio scales of subjective magnitude. A variability model has been proposed previously to account for this departure from linearity. This article examines the model in the light of the empirical relations that enter into it: the ratio scale of subjective magnitude, the corresponding category scale, and the variability of judgments in both physical and psychological units. These relations are determined, through repeated measurement with a single observer, for the psychological continuum, loudness, and its inverse, softness. The ratio scales are shown to be reciprocals, and the category scales complements. …

Changes In Voice-Onset Time In Speakers With Cochlear Implants, Harlan Lane, Jane Wozniak, Joseph Perkell

Harlan Lane

Voice-onset time (VOT) and syllable duration were measured for the English plosives in /Cɑd/ (C=consonant) context spoken by four postlingually deafened recipients of multichannel (Ineraid) cochlear implants. Recordings were made of their speech before, and at intervals following, activation of the speech processors of their implants. Three patients reduced mean syllable duration following activation. Using measures of VOT and syllable duration from speakers with normal hearing [Volaitis and Miller, J. Acoust. Soc. Am. 92, 723–735 (1992)] and from the subjects of this study, VOT is shown to vary approximately linearly with syllable duration over the ranges produced here. Therefore, the …

Foreign Accent And Speech Distortion, Harlan Lane

Harlan Lane

Speech distortion is defined broadly as any operation that evokes inappropriate behavior by a listener in response to speech. Two categories of distorting operations are distinguished: (1) response-independent, in which the transfer function applied to the original speech signal is not determined by the probable response of the listener (e.g., masking, filtering); and (2) response-dependent, in which the distorting operation is related to the probable response of the listener during undistorted transmission and therefore may be specified in linguistic terms (e.g., foreign accent). Two experiments examine the effects and interactions of these two types of distortion. Twenty-four Midwest Americans listened …

Effects Of Short-Term Auditory Deprivation On Speech Production In Adult Cochlear Implant Users, Mario A. Svirsky, Harlan Lane, Joseph S. Perkell, Jane Wozniak

Harlan Lane

Speech production parameters of three postlingually deafened adults who use cochlear implants were measured: after 24 h of auditory deprivation (which was achieved by turning the subject's speech processor off); after turning the speech processor back on; and after turning the speech processor off again. The measured parameters included vowel acoustics [F1, F2, F0, sound-pressure level (SPL), duration and H1–H2, the amplitude difference between the first two spectral harmonics, a correlate of breathiness] while reading word lists, and average airflow during the reading of passages. Changes in speech processor state (on-to-off or vice versa) were accompanied by numerous changes in …
