Latino Family Variables And Sexual Activity In Latino Adolescents, Brittany Nicole Barber Mar 2010

Latino Family Variables And Sexual Activity In Latino Adolescents, Brittany Nicole Barber

Counselor Education and Counseling Psychology Research Exchange Conference

Researchers’ focused examination of Latino adolescents’ cultural values and sexual activity has yielded questions regarding the cultural- and gender-specific attitudes and practices of these youth (Deardorff, Tschann, & Flores, 2008). Cultural values include family-related variables such as different aspects of familism, parent-adolescent communication, and parental monitoring, which have been found to decrease adolescents’ engagement in other negative activities such as aggressive behavior, (Dishion & McMahon, 1998), substance use (Estrada, Rabow, & Watts, 1982), and delinquency (Clark & Shields, 1997). Research investigating these risk behaviors has often implicated Latino adolescents’ level of assimilation to White, mainstream society as a potential risk …


Language Outcome After Left Anterior Temporal Lobectomy In Patients With Discordant Functional Magnetic Resonance Imaging And Intracarotid Sodium Amobarbital Testing Results, Julie K. Janecek Mar 2010

Language Outcome After Left Anterior Temporal Lobectomy In Patients With Discordant Functional Magnetic Resonance Imaging And Intracarotid Sodium Amobarbital Testing Results, Julie K. Janecek

Counselor Education and Counseling Psychology Research Exchange Conference

Language Outcome after Left Temporal Anterior Lobectomy in Patients with Discordant Functional Magnetic Resonance Imaging and Intracarotid Sodium Amobarbital Testing Results Rationale: Previous research has examined concordance rates between Wada and fMRI language lateralization indices (LIs) and has yielded variable results with limited post-surgical language outcome data. Therefore, additional evidence of the concurrent and predictive validity of fMRI LIs is needed. We will calculate Wada/fMRI LI concordance rates in the largest sample to date, investigate predictors of discordance and examine the ability of each procedure to predict language outcome in discordant cases. Methods: A consecutive series of 229 presurgical epilepsy …

Pr. Mamoudou H. DICKO, PhD

The essential oil of jasminum sambac from Djibouti was subjected to screening for their possible antioxidant activity by two complementary test systems, namely DPPH free radical scavenging and beta-carotene-linoleic acid assays. Butylated hydroxytoluene (BHT) was used as positive control in both test systems. In the DPPH test system, the IC50 value of essential oil and methanol extract were respectively 7.43 and 2.30 μg/ml. In the beta-carotene-linoleic acid system, oxidation was effectively inhibited by Jasminum sambac, the RAA value of essential oil and methanol extract were respectively 96.6 and 93.9%. When compared to BHT, the essential oil and methanol extract had …


Theta-Activity In Anterior Cingulate Cortex Predicts Task Rules And Their Adjustments Following Errors, Thilo Womelsdorf, Kevin Johnston, Martin Vinck, Stefan Everling Mar 2010

Theta-Activity In Anterior Cingulate Cortex Predicts Task Rules And Their Adjustments Following Errors, Thilo Womelsdorf, Kevin Johnston, Martin Vinck, Stefan Everling

Brain and Mind Institute Researchers' Publications

Accomplishing even simple tasks depend on neuronal circuits to configure how incoming sensory stimuli map onto responses. Controlling these stimulus-response (SR) mapping rules relies on a cognitive control network comprising the anterior cingulate cortex (ACC). Single neurons within the ACC convey information about currently relevant SR mapping rules and signal unexpected action outcomes, which can be used to optimize behavioral choices. However, its functional significance and the mechanistic means of interaction with other nodes of the cognitive control network remain elusive and poorly understood. Here, we report that core aspects of cognitive control are encoded by rhythmic theta-band activity within …


Bold Signal In Both Ipsilateral And Contralateral Retinotopic Cortex Modulates With Perceptual Fading, Po-Jang Hsieh, Peter U. Tse Mar 2010

Bold Signal In Both Ipsilateral And Contralateral Retinotopic Cortex Modulates With Perceptual Fading, Po-Jang Hsieh, Peter U. Tse

Dartmouth Scholarship

Under conditions of visual fixation, perceptual fading occurs when a stationary object, though present in the world and continually casting light upon the retina, vanishes from visual consciousness. The neural correlates of the consciousness of such an object will presumably modulate in activity with the onset and cessation of perceptual fading.

Method: In order to localize the neural correlates of perceptual fading, a green disk that had been individually set to be equiluminant with the orange background, was presented in one of the four visual quadrants; Subjects indicated with a button press whether or not the disk was subjectively visible …

The purpose of this study was to characterize transit noise and riders' exposure to noise on the BART system using three dosimetry metrics.


Countervailing Power In Wholesale Pharmaceuticals, Sara F. Ellison, Christopher M. Snyder Mar 2010

Countervailing Power In Wholesale Pharmaceuticals, Sara F. Ellison, Christopher M. Snyder

Dartmouth Scholarship

Using data on wholesale prices for antibiotics sold to U.S. drugstores, we test the growing theoretical literature on ‘countervailing power’ (a term for the ability of large buyers to extract discounts from suppliers). Large drugstores receive a modest discount for antibiotics produced by competing suppliers but no discount for antibiotics produced by monopolists. These findings support theories suggesting that supplier competition is a prerequisite for countervailing power. As further evidence for the importance of supplier competition, we find that hospitals receive substantial discounts relative to drugstores, attributed to hospitals' greater ability to induce supplier competition through restrictive formularies.

Hair Whorls In The Dog (Canis Familiaris), Part Ii: Asymmetries, Lisa M. Tomkins, Paul Mcgreevy Mar 2010

Hair Whorls In The Dog (Canis Familiaris), Part Ii: Asymmetries, Lisa M. Tomkins, Paul Mcgreevy

Anatomy Collection

In horses and cattle, hair whorls have been shown to act as a structural marker of reactivity and behavioral lateralization. Few studies on canine whorls have been reported and none have assessed whorl position or direction of flow. This study describes the distribution and characteristics of whorl in each of 10 regions in which whorls are typically located in dogs. Hair whorls were assessed in dogs (n = 120) and were recorded as clockwise or counterclockwise in the cephalic, cervical (dorsal, lateral, ventral), thoracic and brachial axillary, chest, shoulders, elbows, abdominal, and ischiatic regions. Bilateral whorls, including brachial axillary, elbow, …

Changing Po2licy: The Elements For Improving Childhood Asthma Outcomes, Anne Rossier Markus, Meagan Lyon, Sara J. Rosenbaum

Geiger Gibson/RCHN Community Health Foundation Research Collaborative

Childhood asthma is a serious and chronic health issue that affects one in seven U.S. children and their families, compromising their health and quality of life and placing a heavy financial burden on families as well as an enormous strain on the health care system. Treating, managing, and ultimately preventing and reducing the burden of asthma represents a critical test of the ability of the U.S. health system – health insurers, clinical care providers, and public health agencies – to work together. Our investigation found that, as a country, we already know enough to act and improve life for the …

Social inequality and environmental degradation are motivating informed young people into action and connecting impoverished regions of the world with students in more developed nations. This Social Sciences senior project is to analyze an alternative development model designed by a group of Californian university students. The project, named Chimeneas de la Esperanza, is designed to help impoverished Nicaraguan women start a ceramics business. The major hurdle of this mission is to establish a market for the ceramics product. Energy efficient ceramic stoves and smoke ventilating chimneys would benefit the community and avoid an impacted crafts market. The project encompasses ideas …


Conceptions Regarding Children’S Health: An Examination Of Ethnotheories In A Sending And Receiving Community, Maria Rosario De Guzman, Jennifer Deleon, Gloria Gonzalez-Kruger, Rodrigo Cantarero Mar 2010

Conceptions Regarding Children’S Health: An Examination Of Ethnotheories In A Sending And Receiving Community, Maria Rosario De Guzman, Jennifer Deleon, Gloria Gonzalez-Kruger, Rodrigo Cantarero

Department of Child, Youth, and Family Studies: Faculty Publications

Ethnotheories are beliefs that adults hold about children and the factors that impact upon their development. Scholars suggest that “ethnotheories” serve as cultural models that underlie motivations for parenting practices and the way adults organize children’s early experiences. This study examines Mexican adults’ ethnotheories about children’s health in two communities that are linked by transnational migrants and serve as sending and receiving communities for workers. Forty-four Mexican adults in six focus groups discussed well-being issues affecting children in their communities. Qualitative analyses using grounded theory revealed a complex conception of children’s health issues that included physical, psychological, and behavioral components …


Psychometric Properties Of The Psychopathic Personality Inventory In A Non-Criminal Population, Julie Madeleine Woltil Mar 2010

Psychometric Properties Of The Psychopathic Personality Inventory In A Non-Criminal Population, Julie Madeleine Woltil

Loma Linda University Electronic Theses, Dissertations & Projects

The Psychopathic Personality Inventory (PPI) is a self-report measure which was created to identify the personality traits of psychopathy in noncriminal populations. These personality traits were grouped into eight subscales in the PPI including Machiavellian Egocentricity, Social Potency, Coldheartedness, Carefree Nonplanfulness, Fearlessness, Blame Externalization, Impulsive Nonconformity and Stress Immunity. The hypothesized relationships and factor structure of this study follow the theory of psychopathy as being a disorder rooted in antisocial behaviors (often aggressive and impulsive in nature) and inappropriate emotional reactivity (characterized as a lack in empathy and anxiety). A confirmatory factor analysis was done with an ethnically diverse undergraduate …

The President's Emergency Plan For Aids Relief (Pepfar): A Social Work Ethical Analysis And Recommendations, Robert J. Barney, Stephan L. Buckingham, Judith M. Friedrich, Lisa M. Johnson, Michael A. Robinson, Bibhuti K. Sar

The Journal of Sociology & Social Welfare

The President's Emergency Plan for AIDS Relief (PEPFAR) is the most recent international social program instituted by the U.S. Government to combat HIV/AIDS. Since its inception in 2003, this foreign policy initiative has dedicated $63 billion for HIV/AIDS prevention and treatment in foreign countries. Despite PEPFAR's many accomplishments, it continues to promote controversial prevention strategies. This paper analyzes these prevention strategies, utilizing social work values as described in the NASW Code of Ethics. Policy, practice, and research implications are discussed.

A Survey Of The Management And Development Of Captive African Elephant (Loxodonta Africana) Calves: Birth To Three Months Of Age, Nicole L. Kowalski, Robert H.I. Dale, Christa L. H. Mazur

Scholarship and Professional Work - LAS

We used four surveys to collect information about the birth, physical growth, and behavioral development of 12 African elephant calves born in captivity. The management of the birth process and neonatal care involved a variety of standard procedures. All of the calves were born at night, between 7PM and 7AM. The calves showed a systematic progression in behavioral and physical development, attaining developmental milestones at least a quickly as calves in situ. This study emphasized birth-related events, changes in the ways that calves used their trunks, first instances of behaviors, and interactions of the calves with other, usually adult, elephants. …


Gating Of Vibrotactile Detection During Visually Guided Bimanual Reaches, Gavin Buckingham, David Carey, Francisco Colino, John Degrosbois, Gordon Binsted Feb 2010

Gating Of Vibrotactile Detection During Visually Guided Bimanual Reaches, Gavin Buckingham, David Carey, Francisco Colino, John Degrosbois, Gordon Binsted

Gavin Buckingham

It is far more difficult to detect a small tactile stimulation on a finger that is moving compared to when it is static. This suppression of tactile information during motion, known as tactile gating, has been examined in some detail during single-joint movements. However, the existence and time course of this gating has yet to be examined during visually guided multi-joint reaches, where sensory feedback may be paramount. The current study demonstrated that neurologically intact humans are unable to detect a small vibratory stimulus on one of their index fingers during a bimanual reach toward visual targets. By parametrically altering …


The Evolution Of The Theoretical Foundations Of Punctuated Equilibrium Theory In Public Policy, Michael S. Givel Feb 2010

The Evolution Of The Theoretical Foundations Of Punctuated Equilibrium Theory In Public Policy, Michael S. Givel

Michael S. Givel

Punctuated equilibrium theory in public policy replicated from biological punctuated equilibrium theory has concluded that public policies alternate between stasis and punctuation. However, recent research on Pacific Northwest forest policy, U.S. state tobacco policy, and U.S federal auto efficiency policy have found no punctuations despite an attempt to do so. What is the efficacy of using biological punctuated equilibrium theory to also explain punctuated equilibrium in public policy? Significant differences exist between biological and public policy punctuated equilibrium theory including time frames for change, what constitutes outside disturbances of equilibrium, venues of punctuated equilibrium, levels of analysis for change, and …

14. Investigative Interviewing Of The Child., Thomas D. Lyon

Thomas D. Lyon

Children, if questioned in a supportive manner, are capable of providing enormous amounts of productive information in response to open-ended questions. The irony is that many direct and suggestive methods once thought necessary to overcome abused children's reluctance to disclose abuse have been found counterproductive in two ways: they minimize the number of details in true allegations at the same time that they increase the risk of false allegations.

21. Children’S Reasoning About Disclosing Adult Transgressions: Effects Of Maltreatment, Child Age, And Adult Identity., Thomas D. Lyon, Elizabeth C. Ahern, Lindsay A. Malloy, Jodi A. Quas

Thomas D. Lyon

A total of two hundred ninety-nine 4- to 9-year-old maltreated and nonmaltreated children of comparable socioeconomic status and ethnicity judged whether children should or would disclose unspecified transgressions of adults (instigators) to other adults (recipients) in scenarios varying the identity of the instigator (stranger or parent), the identity of the recipient (parent, police, or teacher), and the severity of the transgression (‘‘something really bad’’ or ‘‘something just a little bad’’). Children endorsed more disclosure against stranger than parent instigators and less disclosure to teacher than parent and police recipients. The youngest maltreated children endorsed less disclosure than nonmaltreated children, but …

Geiger Gibson/RCHN Community Health Foundation Research Collaborative

During times of economic crisis, community health centers and other health care safety net providers become even more vital to the communities they serve. The current downturn, with its high levels of unemployment and enormous impact on family incomes, carries major implications for health insurance coverage. The American Recovery and Reinvestment Act (ARRA), signed into law on February 17, 2009, provided slightly more than two billion dollars to community health centers for capital improvements, expansion (or retention) of personnel and services, and adoption of health information technology. All of these uses not only support health centers' mission to serve populations …


Smart Density: A More Accurate Method Of Measuring Rural Residential Density For Health-Related Research, Peter M. Owens, Linda Titus-Ernstoff, Lucinda Gibson, Michael L. Beach, Sandy Beauregard, Madeline A. Dalton Feb 2010

Smart Density: A More Accurate Method Of Measuring Rural Residential Density For Health-Related Research, Peter M. Owens, Linda Titus-Ernstoff, Lucinda Gibson, Michael L. Beach, Sandy Beauregard, Madeline A. Dalton

Dartmouth Scholarship

Studies involving the built environment have typically relied on US Census data to measure residential density. However, census geographic units are often unsuited to health-related research, especially in rural areas where development is clustered and discontinuous. We evaluated the accuracy of both standard census methods and alternative GIS-based methods to measure rural density.
