The Relations Among Multiple Risks, Parenting Styles, and Chinese American Children's Internalizing and Externalizing Problems

This study examined the prospective effects of multiple risks on the internalizing and externalizing problems of 258 1st and 2nd generation Chinese American school-aged children, as well as the mediating and moderating roles of parenting styles. When examining the relations between risk domains and children's behavioral adjustment, children's low self-regulation and negative emotionality, single-parent family structure, and gaps in parent-child cultural orientations were found to be unique predictors of adjustment outcomes two years later. The multiple risk index, which represented the joint effects of uniquely predictive risk variables, was related to higher levels of child-reported internalizing and externalizing problems. Similarly, the cumulative risk index, which represented the number of risk factor exposures, was also associated with increased internalizing and externalizing problems as reported by children. Though we did not find support for parenting styles as mediators, results did indicate that authoritarian parenting interacted with the multiple and cumulative risk indexes. High authoritarian parenting had a tendency to strengthen the relation between the multiple risk index and increased teacher-reported internalizing problems, while low authoritarian parenting had a tendency to attenuate the relation between cumulative risk and parent-reported internalizing problems.
LONGITUDINAL EXAMINATION OF DISORDERED EATING CORRELATES IN COLLEGIATE FEMALE GYMNASTS

of Thesis Presented to the Graduate School of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Master of Science in Exercise and Sport Sciences LONGITUDINAL EXAMINATION OF DISORDERED EATING CORRELATES IN COLLEGIATE FEMALE GYMNASTS By Jessica C. Halvorsen August 2003 Chair: Heather A. Hausenblas Major Department: Exercise and Sport Sciences The purpose of this study was to longitudinally examine the eating disorder correlates of body dissatisfaction, perfectionism, drive for thinness, and social physique anxiety of female gymnasts and nonathletes over a six-month period. Participants completed the Social Physique Anxiety Scale and the Body Dissatisfaction, Drive for Thinness, and Perfectionism subscales of the Eating Disorder Inventory-2 in September (preseason) and in March (competitive season). One hundred and eleven nonathletes and 102 gymnasts completed the Time 1 questionnaire. The Time 1 response rate for the nonathletes was 72% and the response rate for the gymnasts was 98%. For Time 2, 17 nonathletes completed the questionnaire for a response rate of 15%, and 79 gymnasts completed the Time 2 questionnaire for a response rate of 77%. I found that the gymnasts and nonathletes did not differ significantly on the eating disorder correlates at Time 1. Because of the poor response rate of the nonathletes for the Time 2 data collection, time differences were examined only for the gymnasts. I found no significant time differences
Lightweight Key Distribution for Secure Routing and Secure Information Propagation

: MANET is considered as a type of wireless sensor networking, it can be affected by many types of attack specifically on clusters and has main concern in the loss of information from the MANETs. Our proposed technique is concerned with selective packet drop from the selective forwarding attack. With this packet, throughput of the system get affected and results in the reduction of throughput. MANET associate with the network of mobile nodes. With the help of secure routing and key management schemes we can secure our MANET. For the proposed technique we have studied the existing models related to routing and key management and find out their shortcomings to far better model than the existing ones. In the proposed paper, security schemes for MANET are proposed that include lightweight key exchange scheme having randomized key generation scheme that provide security to data propagation in the MANET clusters. Experimental result shows that proposed technique gives better results as compared to existing technique.
Immunological Barriers to Embryonic Stem Cell-Derived Therapies

Replacement of diseased tissues with healthy cells derived from embryonic stem (ES) cells has a potential to become, in the future, a better alternative to current treatments of a number of conditions characterized by irreversible tissue injury, such as heart and liver failure, diabetes mellitus and neurodegeneration. However, several obstacles have to be overcome before this new therapeutic modality becomes part of a standard clinical practice. First of all, ethical and safety issues have to be resolved, the methodologies must be developed to enable obtaining sufficient amounts of differentiated cells, and the immune rejection of allogeneic cells must be prevented in order to ensure their long-term engraftment and function. Data on immunological properties of human and murine ES cells and their differentiated derivatives are controversial, ranging from those claiming unique immune-privileged properties for ES cells to those which refute these conclusions. This indicates that much more research is required to definitively understand the immunological features and engraftment capacity of ES cell derivatives. We review here the current state of the art in this new and exciting field of ES cell immunology and discuss the implications of these findings for the development of ES cell-based therapies.
Dissecting life with a Jewish scalpel: a qualitative analysis of Jewish-centered family life.

This article highlights findings from a qualitative analysis of the ways in which Jewish families identify how Judaism influences their lives. A theoretical sample of two religious and two cultural families were chosen from a larger sample of 48 Jewish families in Central New York. The qualitative part of this study, which was part of a larger multimethod investigation, was done in order to gather inductively any data that would allow the researchers to build a theory about a particular type of ethnic identity--Jewish identity--and how it affects family dynamics. Eleven categories emerged from this study, which suggest that this particular type of ethnic identity influences many family dynamics, for example, styles of communicating, parenting, values, and family rituals. The participants seem to dissect the world with a "Jewish scalpel. " This "scalpel" informs their daily interactions, their parenting styles, and their childrens' self-perceptions.
c9t11-Conjugated linoleic acid-rich oil fails to attenuate wasting in colon-26 tumor-induced late-stage cancer cachexia in male CD2F1 mice.

SCOPE Cancer cachexia is characterized by muscle and adipose tissue wasting caused partly by chronic, systemic inflammation. Conjugated linoleic acids (CLAs) are a group of fatty acids with various properties including anti-inflammatory cis9, trans11 (c9t11)-CLA and lipid-mobilizing trans10, cis12 (t10c12)-CLA. The purpose of this study was to test whether dietary supplementation of a c9t11-CLA-rich oil (6:1 c9t11:t10c12) could attenuate wasting of muscle and adipose tissue in colon-26 adenocarcinoma-induced cachexia in mice. METHODS AND RESULTS Loss of body weight, muscle and adipose tissue mass caused by tumors were not rescued by supplementation with the c9t11-CLA-rich oil. In quadriceps muscle, c9t11-CLA-rich oil exacerbated tumor-induced gene expression of inflammatory markers tumor necrosis factor-α, IL-6 receptor and the E3 ligase MuRF-1 involved in muscle proteolysis. In epididymal adipose tissue, tumor-driven delipidation and atrophy was aggravated by the c9,t11-CLA-rich oil, demonstrated by further reduced adipocyte size and lower adiponectin expression. However, expression of inflammatory cytokines and macrophage markers were not altered by tumors, or CLA supplementation. CONCLUSION These data suggest that addition of c9t11-CLA-rich oil (0.6% c9t11, 0.1% t10c12) in diet did not ameliorate wasting in mice with cancer cachexia. Instead, it increased expression of inflammatory markers in the muscle and increased adipose delipidation.
WATER HAMMER IN PIPE LINE WITH DIFFERENT CHARACTERISTICS OF VALVE CLOSING AND UNSTEADY WALL FRICTION

This paper presents an analytical investigation of water hammer pressure variation in a reservoir-pipe-valve system. Laplace transform method is used to get the analytical solutions for different characteristics of the valve closing. Specifically, sudden valve closing and piecewise linear closing are used, the latter can be treated as approximated arbitrary characteristics of valve closing. Unsteady wall friction is also included. The new solutions compare well with the previous experimental data. The results show that this solution is suitable for water hammer with laminar and low Reynolds number turbulent unsteady flow. The effects of different characteristics of the valve closing on the water hammer pressure variations are also studied. This solution can be a better choice for optimization of valve closing to reduce the maximum water hammer pressure.
Perceptions of family functioning in adolescents who self‐harm

This study compares the self-reported family functioning of 21 adolescents presenting at four UK medical wards with self-harming behaviour with those obtained from a sample of adolescents drawn from the local community. Adolescents hospitalized for self-harm reported that their families were more dysfunctional than healthy controls on the family perceptions scale. However, this difference was not observed when covariates such as emotional and behavioural distress were controlled for. Poor levels of agreement between adolescents and adult family members in relation to family perceptions were also observed. The findings suggest that adolescents who engage in significant self-harm perceive impairments in their family functioning. These reported impairments may be the result of concurrent emotional and behavioural distress or some form of interaction between family functioning and distress. A comprehensive family assessment to detect absolute changes and disparities in perceived family functioning may therefore help guide family interventions in this context. Practitioner points * Adolescents who are hospitalized for self-harm report significant impairments in family functioning compared with healthy controls. * Adolescent and adult family members appear to disagree on the degree of impaired family functioning. * A comprehensive family assessment may therefore help guide family interventions in hospitalized adolescents.

Activity-Stability Relationships in Extremophilic Enzymes*

Psychrophilic, mesophilic, and thermophilic α-amylases have been studied as regards their conformational stability, heat inactivation, irreversible unfolding, activation parameters of the reaction, properties of the enzyme in complex with a transition state analog, and structural permeability. These data allowed us to propose an energy landscape for a family of extremophilic enzymes based on the folding funnel model, integrating the main differences in conformational energy, cooperativity of protein unfolding, and temperature dependence of the activity. In particular, the shape of the funnel bottom, which depicts the stability of the native state ensemble, also accounts for the thermodynamic parameters of activation that characterize these extremophilic enzymes, therefore providing a rational basis for stability-activity relationships in protein adaptation to extreme temperatures.
Teorías implícitas sobre la pedagogía de los formadores que orientan la práctica educativa en el Programa de Cultura Informacional del Sistema de Bibliotecas de la Universidad de Antioquia

The present article sets out to explore the existence of implicit pedagogical theories among the Information Culture Program (ICP) instructors at the Sistema de Bibliotecas of the Universidad de Antioquia. Using a case-study approach, the pedagogical practices at the library are analyzed. Moreover, the Narrative-Conceptual Pedagogical Framework (NCPF) serves as a theoretical vantage for the conceptualization of the data. The results show that both instructional and knowledge transmission practices at the Central Library are not pedagogically-driven. This points to a need to consolidate a pedagogical mindset among instructors through the creation of suitable spaces for reflection capable of laying out the foundations of an informational culture.

Perfusion Imaging of Brain Tumors Using Arterial Spin-Labeling: Correlation with Histopathologic Vascular Density

BACKGROUND AND PURPOSE: We investigated the relationship between tumor blood-flow measurement based on perfusion imaging by arterial spin-labeling (ASL-PI) and histopathologic findings in brain tumors. MATERIALS AND METHODS: We used ASL-PI to examine 35 patients with brain tumors, including 11 gliomas, 9 meningiomas, 9 schwannomas, 1 diffuse large B-cell lymphoma, 4 hemangioblastomas, and 1 metastatic brain tumor. As an index of tumor perfusion, the relative signal intensity (SI) of each tumor (%Signal intensity) was determined as a percentage of the maximal SI within the tumor per averaged SI within normal cerebral gray matter on ASL-PI. Relative vascular attenuation (%Vessel) was determined as the total microvessel area per the entire tissue area on CD-34–immunostained histopathologic specimens. MIB1 indices of gliomas were also calculated. The differences in %Signal intensity among different histopathologic types and between high- and low-grade gliomas were compared. In addition, the correlations between %Signal intensity and %Vessel or MIB1 index were evaluated in gliomas. RESULTS: Statistically significant differences in %Signal intensity were observed between hemangioblastomas versus gliomas (P < .005), meningiomas (P < .05), and schwannomas (P < .005). Among gliomas, %Signal intensity was significantly higher for high-grade than for low-grade tumors (P < .05). Correlation analyses revealed significant positive correlations between %Signal intensity and %Vessel in 35 patients, including all 6 histopathologic types (rs = 0.782, P < .00005) and in gliomas (rs = 0.773, P < .05). In addition, in gliomas, %Signal intensity and MIB1 index were significantly positively correlated (rs = 0.700, P < .05). CONCLUSION: ASL-PI may predict histopathologic vascular densities of brain tumors and may be useful in distinguishing between high- and low-grade gliomas and in differentiating hemangioblastomas from other brain tumors.
Finding Representative Objects with Sparse Modeling

It is often useful to summarize a dataset by picking a small number of exemplars. This aids in visualizing and interpreting datasets; it is also applicable e.g. in reducing the search space for robotic motion planners or in reducing the size of a training set given to a classifier. We give an approach inspired by sparse coding that picks a few elements which can best represent the entire dataset through sparse linear combinations. We formulate the approach as a convex program, give algorithms based on generalized gradient descent and coordinate descent, and investigate the dual problem. Finally, we evaluate the efficacy of the optimization algorithms and the quality of the results on several synthetic and real-world datasets.
On the source of the late-time infrared luminosity of SN 1998S and other Type II supernovae

We present late-time near-infrared (NIR) and optical observations of the Type IIn SN 1998S. The NIR photometry spans 333-1242 d after explosion, while the NIR and optical spectra cover 333-1191 and 305-1093 d, respectively. The NIR photometry extends to the M' band (4.7 mum), making SN 1998S only the second ever supernova for which such a long IR wavelength has been detected. The shape and evolution of the H and He I 1.083-mum line profiles indicate a powerful interaction with a progenitor wind, as well as providing evidence of dust condensation within the ejecta. The latest optical spectrum suggests that the wind had been flowing for at least 430 yr. The intensity and rise of the HK continuum towards longer wavelengths together with the relatively bright L' and M' magnitudes show that the NIR emission was due to hot dust newly formed in the ejecta and/or pre-existing dust in the progenitor circumstellar medium (CSM). The NIR spectral energy distribution (SED) at about 1 yr is well described by a single-temperature blackbody spectrum at about 1200 K. The temperature declines over subsequent epochs. After similar to2 yr, the blackbody matches are less successful, probably indicating an increasing range of temperatures in the emission regions. Fits to the SEDs achieved with blackbodies weighted with lambda(-1) or lambda(-2) emissivity are almost always less successful. Possible origins for the NIR emission are considered. Significant radioactive heating of ejecta dust is ruled out, as is shock X-ray-precursor heating of CSM dust. More plausible sources are (a) an IR echo from CSM dust driven by the ultraviolet/optical peak luminosity, and (b) emission from newly-condensed dust which formed within a cool, dense shell produced by the ejecta shock/CSM interaction. We argue that the evidence favours the condensing dust hypothesis, although an IR echo is not ruled out. Within the condensing-dust scenario, the IR luminosity indicates the presence of at least 10(-3) M. of dust in the ejecta, and probably considerably more. Finally, we show that the late-time (K-L')(0) evolution of Type II supernovae may provide a useful tool for determining the presence or absence of a massive CSM around their progenitor stars.
Adaptive optics for vision: the eye's adaptation to point spread function.

PURPOSE Despite the fact that ocular aberrations blur retinal images, our subjective impression of the visual world is sharp, which suggests that the visual system compensates for subjective influence. If the brain adjusts for specific aberrations of the eye, vision should be clearest when looking through a subject's typical wave aberration rather than through an unfamiliar one. We used adaptive optics techniques to control the eye's aberrations in order to evaluate this hypothesis. METHODS We used adaptive optics to produce point spread functions (PSFs) that were rotated versions of the eye's typical PSF by angles in 45 degrees intervals. Five normal subjects were asked to view a stimulus with their own PSF or with a rotated version, and to adjust the magnitude of the aberrations in the rotated case to match the subjective blur of the stimulus to that seen when the wave aberration was in typical orientation. RESULTS The magnitude of the rotated wave aberration required to match the blur with the typical wave aberration was 20% to 40% less, indicating that subjective blur for the stimulus increased significantly when the PSF was rotated. CONCLUSION These results support the hypothesis that the neural visual system is adapted to an eye's aberrations and has important implications for correcting higher order aberrations with customized refractive surgery or contact lenses. The full visual benefit of optimizing optical correction requires that the nervous system compensate for the new correction.
Comparison of anterior cingulate vs. insular cortex as targets for real-time fMRI regulation during pain stimulation

Real-time functional magnetic resonance imaging (rt-fMRI) neurofeedback allows learning voluntary control over specific brain areas by means of operant conditioning and has been shown to decrease pain perception. To further increase the effect of rt-fMRI neurofeedback on pain, we directly compared two different target regions of the pain network, notably the anterior insular cortex (AIC) and the anterior cingulate cortex (ACC). Participants for this prospective study were randomly assigned to two age-matched groups of 14 participants each (7 females per group) for AIC and ACC feedback. First, a functional localizer using block-design heat pain stimulation was performed to define the pain-sensitive target region within the AIC or ACC. Second, subjects were asked to down-regulate the BOLD activation in four neurofeedback runs during identical pain stimulation. Data analysis included task-related and functional connectivity analysis. At the behavioral level, pain ratings significantly decreased during feedback vs. localizer runs, but there was no difference between AIC and ACC groups. Concerning neuroimaging, ACC and AIC showed consistent involvement of the caudate nucleus for subjects that learned down-regulation (17/28) in both task-related and functional connectivity analysis. The functional connectivity toward the caudate nucleus is stronger for the ACC while the AIC is more heavily connected to the ventrolateral prefrontal cortex. Consequently, the ACC and AIC are suitable targets for real-time fMRI neurofeedback during pain perception as they both affect the caudate nucleus, although functional connectivity indicates that the direct connection seems to be stronger with the ACC. Additionally, the caudate, an important area involved in pain perception and suppression, could be a good rt-fMRI target itself. Future studies are needed to identify parameters characterizing successful regulators and to assess the effect of repeated rt-fMRI neurofeedback on pain perception.
