What happens when fathers and children talk about each others' mental states in play?: The development of social representations and affect regulation capacity

Mentalization refers to the capacity to understand one’s own and other’s behaviors, regarding the underlying mental states and intentions (Slade, 2005, p.269). The study aimed to explore the relations between paternal attachment security and mentalization levels and children’s emotion regulation, social representations and mentalization levels in father-child play. Participants consisted of 40 father-child dyads referred to Istanbul Bilgi University Psychological Counseling Center for psychological counseling. Children were 7 years old, on average. Two different coding systems were used to assess mentalization levels and play behaviors. Father and children’s play-related (pretense) mentalizations were observed having positive correlations. Fathers’ other and self related mentalizations were found to be positively correlated with children’s self and other related mentalizations, respectively. Father’s mentalization in pretend play also showed positive correlation with children’s social representations in play. However, no significant correlations were found between fathers’ mentalization levels, attachment security and children’s emotion regulation. As study was consisted of a clinical sample, the results were primarily discussed over the possible differences in clinical father-child dyads by considering the empirical findings, psychological theories (object-relations and psychodynamic) and the newly developing role of the fathers. iii iv ÖZET Zihinselleştirme, kişinin kendinin ve karşısındakinin hareketlerinin altında yatan amaç ve niyetleri anlayabilme kapasitesidir (Slade, 2005, p.269). Bu araştırma, baba-çocuk oyunu içerisinde, babaların bağlanma güvenliği, zihinselleştirme seviyeleri ve çocukların duygu regülasyonu, sosyal temsilleri ve zihinselleştirme seviyeleri arasındaki ilişkiyi araştırmayı hedeflemektedir. Katılımcılar, İstanbul Bilgi Üniversitesi’nin Psikolojik Danışmanlık Merkezi’ne başvurmuş olan, 40 adet baba ve çocuğudur. Katılımcı olan çocukların ortalama yaşı 7’dir. Zihinselleştirme seviyeleri ve oyun içindeki davranışlar iki farklı kodlama sistemi ile ölçülmüştür. Babaların ve çocukların “-mış gibi” oyun içindeki zihin durum sözcükleri arasında pozitif ilişki gözlemlenmiştir. Babaların kendileri ve diğer kişi hakkında kullandıkları zihin durum sözcükleri, sırasıyla, çocukların diğer kişiler ve kendilerine yönelik zihin durum sözcükleriyle pozitif ilişkili bulunmuştur. Bunun yanı sıra, babaların “-mış gibi” oyun içerisinde kullandığı zihin durumları sözcükleri ile çocukların sosyal temsilleri arasında pozitif bir ilişki gözlemlenmiştir. Fakat, babaların zihin durum sözcükleri kullanımı ile bağlanma güvenlikleri ve çocukların oyun duygu regülasyonları arasında herhangi bir ilişki bulunamamıştır. Sonuçlar, katılımcıların klinik şikayetlere sahip olmaları göz önünde bulundurularak, nesne ilişkileri, psikodinamik teori ve babanın rolleri ışığında tartışılmıştır.

Exploring the Social Construction of Grief and Loss in Spouses Following Bereavement by Cancer

Cancer bereavement may be associated with unique challenges involved in the caregiving experience, particularly for spouses, who commonly adopt this role. However, the dominance of quantitative and diagnostically informed research has produced a-contextual theories, which reinforce increasingly medicalised conceptualisations of grief. In contrast, less attention has been given to the subjective experience in this context, particularly from a discursive perspective. Three focus groups comprising an overall total of six men and 17 women were used to facilitate discussions between spouses who were bereaved by cancer. A Foucauldian-informed discourse analysis was employed to examine how participants constructed grief and loss, and to identify the broader discourses that served to shape these. Additional attention was paid to the rhetorical aspects of these constructions. Three overarching discursive ‘sites’ were identified: i) medicalisation; ii) individualism and iii) productivity and purpose. Analysis of the discursive activity illuminated how these discourses co-existed, creating tensions within constructions that highlighted an increasing professionalisation of grief, and also carried expectations for individuals to manage their grieving in private, via practices of self-regulation. These discourses offered subjugated positions and served to reinforce the power differentials that exist between the bereaved and professionals. However, those constructions that resisted positions of powerlessness and being silenced enabled individuals a greater sense of authority within bereavement and led them to feel more open and connected as a result. The findings draw attention to the expectation for bereaved individuals to protect society from their emotions. This has important implications for how grief may be better supported within clinical psychology settings and points to the need to challenge unhelpful assumptions within society.
Postoperative Spinal Epidural Hematoma: Risk Factor and Clinical Outcome

We report a series of epidural hematomas which cause neurologic deterioration after spinal surgery, and have taken risk factors and prognostic factors into consideration. We retrospectively reviewed the database of 3720 cases of spine operation in a single institute over 7 years (1998 April-2005 July). Nine patients who demonstrated neurologic deterioration after surgery and required surgical decompression were identified. Factors postulated to increase the postoperative epidural hematoma and to improve neurologic outcome were investigated. The incidence of postoperative epidural hematoma was 0.24%. Operation sites were cervical 3 cases, thoracic 2 cases, and lumbar 4 cases. Their original diagnoses were tumor 3 cases, cervical stenosis 2 cases, lumbar stenosis 3 cases and herniated lumbar disc 1case. The symptoms of epidural hematomas were neurologic deterioration and pain. After decompression, clinical outcome revealed complete recovery in 3 cases (33.3%), incomplete recovery in 5 cases (55.6%) and no change in 1 case (11.1%). Factors increasing the risk of postoperative epidural hematoma were coagulopathy from medical illness or anticoagulation therapy (4 cases, 44.4%) and highly vascularized tumor (3 cases, 33.3%). The time interval to evacuation of complete recovery group (29.3 hours) was shorter than incomplete recovery group (66.3 hours). Patients with coagulopathy and highly vascularized tumor were more vulnerable to spinal epidural hematoma. The postoperative outcome was related to the preoperative neurological deficit and the time interval to the decompression.
Mobile Robot Localization using Panoramic Vision and Combinations of Local Feature Region Detectors

This paper presents a vision-based approach for mobile robot localization. The environmental model is topological. The new approach uses a constellation of different types of local affine covariant regions to characterize a pla ce. This type of representation permits a reliable and distinct ive environment modeling. The goal of our work was to find out if using combinations of complementary local feature region detectors improves the localization with respect to using a single region detector. Our experimental results show that although the combination of different covariant affine region detectors increases the number of detected features and th us of potential matches it does not always improve the localizat ion of the robot. Indeed, similarly to single detectors, different combinations also exhibit different strengths and weaknes ses depending on the situation.
Prediagnostic Plasma Vitamin D Metabolites and Mortality among Patients with Prostate Cancer

BACKGROUND Laboratory evidence suggests that vitamin D might influence prostate cancer prognosis. METHODOLOGY/PRINCIPAL FINDINGS We examined the associations between prediagnostic plasma levels of 25(OH)vitamin D [25(OH)D] and 1,25(OH)(2) vitamin D [1,25(OH)(2)D] and mortality among 1822 participants of the Health Professionals Follow-up Study and Physicians' Health Study who were diagnosed with prostate cancer. Cox proportional hazards models were used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) of total mortality (n = 595) and lethal prostate cancer (death from prostate cancer or development of bone metastases; n = 202). In models adjusted for age at diagnosis, BMI, physical activity, and smoking, we observed a HR of 1.22 (95% CI: 0.97, 1.54) for total mortality, comparing men in the lowest to the highest quartile of 25(OH)D. There was no association between 1,25(OH)(2)D and total mortality. Men with the lowest 25(OH)D quartile were more likely to die of their cancer (HR: 1.59; 95% CI: 1.06, 2.39) compared to those in the highest quartile (P(trend) = 0.006). This association was largely explained by the association between low 25(OH)D levels and advanced cancer stage and higher Gleason score, suggesting that these variables may mediate the influence of 25(OH)D on prognosis. The association also tended to be stronger among patients with samples collected within five years of cancer diagnosis. 1,25(OH)(2)D levels were not associated with lethal prostate cancer. CONCLUSIONS/SIGNIFICANCE Although potential bias of less advanced disease due to more screening activity among men with high 25(OH)D levels cannot be ruled out, higher prediagnostic plasma 25(OH)D might be associated with improved prostate cancer prognosis.
Psychological Effect of Personalized Services on Customer`s Website Loyalty in Fashion -Focusing on Cognitive Efficiency, Website Socialness, and Perceived Enjoyment-

Prior research highlighted personalized services as a crucial antecedent to website loyalty, yet little has been discussed on the underlying mechanism. The current study explores the intervening effects of the three psychological constructs in the personalization-loyalty relationship: cognitive efficiency, perceived enjoyment, and socialness. An experiment was conducted with a total of 414 U.S. shoppers on a fictitious e-tail site for jeans that employed different levels of personalized content. The results found that the participants exposed to the high-level personalization condition reported a higher cognitive efficiency and higher socialness perception regarding the fashion e-tail site; however, no direct effect of intensity of e-personalization was found on perceived enjoyment. Cognitive efficiency and enjoyment perceptions on the site significantly increased customers` loyalty intentions regarding the site, while website socialness perception had no direct effect on loyalty intentions. Website socialness showed indirect effects on website loyalty intentions only through cognitive efficiency and perceived enjoyment; however, no direct effect from website socialness was found. Implications and limitations of the study were discussed.
A simple noise reduction disturbance observer and Q-filter design for internal stability

The noise reduction disturbance observer is an unconventional construction of disturbance observer which has the ability of attenuating the high frequency measurement noise as well as the low frequency input disturbance. While retaining the same capabilities, this paper explores a more concise and prevailing version of the noise reduction disturbance observer with a more relaxed almost necessary and sufficient condition for the closed-loop system to be internally stable without requiring the stability of the nominal plant. Moreover, the proposed version is reduced-order compared with the classical disturbance observers in the sense that the two low-pass filters, commonly set to be identical, are now distinct and, as a result, one of them can have order less than the relative degree of the nominal plant. All of which are the direct consequence of a simplified configuration, we additionally present a design method for the two distinct low-pass filters to guarantee the internal stability of the system.
Exploring Different Roles between Service Expectation and Technology Expectation In Citizen's E-Government Continuance Adoption: An Extended Expectation-Confirmation Model

Although Chinese government has got remarkable achievement in e-Government development, the difficult issue that citizen use behaviour cannot last toward many e-Government services has long been troubling to government in different levels. Based on expectation-confirmation theory (ECT), this paper proposed an extended model by divide the expectation and perceived performance into two categories, service perspective and technology perspective, for understanding the different roles of those factors in the process of e-Government continuance adoption. The research plan of an empirical experiment toward the e-Government portal of Beijing, the capital of China for utilizing this extended model was also discussed briefly in the paper.

hPaf1/PD2 interacts with OCT3/4 to promote self-renewal of ovarian cancer stem cells

Cancer stem cells (CSCs), which mediate drug resistance and disease recurrence in several cancers, are therapeutically relevant to ovarian cancer (OC), wherein approximately 80% of patients manifest with tumor recurrence. While there are several markers for ovarian CSCs (OCSCs), the mechanism for their self-renewal maintenance by unique driver/markers is poorly understood. Here, we evaluated the role of hPaf1/PD2, a core component of RNA Polymerase II-Associated Factor (PAF) complex, in self-renewal of OCSCs through marker and functional analyses, including CRISPR/Cas9-silencing of hPaf1/PD2 in OCSCs and provided a possible mechanism for maintenance of OCSCs. Expression of hPaf1/PD2 showed moderate to intense staining in 32.4% of human OC tissues, whereas 67.6% demonstrated basal expression by immunohistochemistry analysis, implying that the minor proportion of cells overexpressing hPaf1/PD2 could be putative OCSCs. Isolated OCSCs showed higher expression of hPaf1/PD2 along with established CSC and self-renewal markers. Knockdown of hPaf1/PD2 in OCSCs resulted in a significant downregulation of CSC and self-renewal markers, and impairment of in vitro tumor sphere (P < 0.05) and colony formation (P = 0.013). Co-immunoprecipitation revealed that OCT3/4 specifically interacts with hPaf1/PD2, and not with other PAF components (Ctr9, Leo1, Parafibromin) in OCSCs, suggesting a complex-independent role for hPaf1/PD2 in OCSC maintenance. Moreover, there was a significant overexpression and co-localization of hPaf1/PD2 with OCT3/4 in OC tissues compared to normal ovary tissues. Our results indicate that hPaf1/PD2 is overexpressed in OCSCs and maintains the self-renewal of OCSCs through its interaction with OCT3/4; thus, hPaf1/PD2 may be a potential therapeutic target to overcome tumor relapse in OC.
Loss of HIV-1–specific CD8+ T Cell Proliferation after Acute HIV-1 Infection and Restoration by Vaccine-induced HIV-1–specific CD4+ T Cells

Virus-specific CD8+ T cells are associated with declining viremia in acute human immunodeficiency virus (HIV)1 infection, but do not correlate with control of viremia in chronic infection, suggesting a progressive functional defect not measured by interferon γ assays presently used. Here, we demonstrate that HIV-1–specific CD8+ T cells proliferate rapidly upon encounter with cognate antigen in acute infection, but lose this capacity with ongoing viral replication. This functional defect can be induced in vitro by depletion of CD4+ T cells or addition of interleukin 2–neutralizing antibodies, and can be corrected in chronic infection in vitro by addition of autologous CD4+ T cells isolated during acute infection and in vivo by vaccine-mediated induction of HIV-1–specific CD4+ T helper cell responses. These data demonstrate a loss of HIV-1–specific CD8+ T cell function that not only correlates with progressive infection, but also can be restored in chronic infection by augmentation of HIV-1–specific T helper cell function. This identification of a reversible defect in cell-mediated immunity in chronic HIV-1 infection has important implications for immunotherapeutic interventions.

State of the art satellite and airborne marine oil spill remote sensing: Application to the BP Deepwater Horizon oil spill" (2012). NASA Publications. Paper 117. a b s t r a c t a r t i c l e i n f o Keywords: Oil spill Deepwater Horizon Remote sensing Lidar Near infrared Thermal infrared Satellite Airborne remote sensing Synthetic aperture radar MODIS Hyperspectral Multispectral Expert system False positives Technology readiness Operational readiness Visible spectrum Oil water emulsions Spill response AVIRIS Synthetic aperture radar UAVSAR Fire CALIPSO Oil slick thickness Laser fluorescence The vast and persistent Deepwater Horizon (DWH) spill challenged response capabilities, which required accurate , quantitative oil assessment at synoptic and operational scales. Although experienced observers are a spill response's mainstay, few trained observers and confounding factors including weather, oil emulsifica-tion, and scene illumination geometry present challenges. DWH spill and impact monitoring was aided by extensive airborne and spaceborne passive and active remote sensing. Oil slick thickness and oil-to-water emulsion ratios are key spill response parameters for containment/cleanup and were derived quantitatively for thick (>0.1 mm) slicks from AVIRIS (Airborne Visible/Infrared Imaging Spectrometer) data using a spectral library approach based on the shape and depth of near infrared spectral absorption features. MODIS (Moderate Resolution Imaging Spectroradiometer) satellite, visible-spectrum broadband data of surface-slick modulation of sunglint reflection allowed extrapolation to the total slick. A multispectral expert system used a neural network approach to provide Rapid Response thickness class maps. Airborne and satellite synthetic aperture radar (SAR) provides synoptic data under all-sky conditions; however, SAR generally cannot discriminate thick (> 100 μm) oil slicks from thin sheens (to 0.1 μm). The UAVSAR's (Uninhabited Aerial Vehicle SAR) significantly greater signal-to-noise ratio and finer spatial resolution allowed successful pattern discrimination related to a combination of oil slick thickness, fractional surface coverage, and emulsification. In situ burning and smoke plumes were studied with AVIRIS and corroborated spaceborne CALIPSO (Cloud Aerosol Lidar and Infrared Pathfinder Satellite Observation) observations of combustion aerosols. CALIPSO and bathymetry lidar data documented shallow subsurface oil, although ancillary data were required for confirmation. Airborne hyperspectral, thermal infrared data have nighttime and overcast collection advantages and were collected as well as MODIS thermal data. However, interpretation challenges and a lack of Rapid Response Products prevented significant use. Rapid Response Products were key to response utilization—data needs are time critical; thus, a high technological readiness level is critical to operational use …
Information, Search, and Price Dispersion

We provide a unified treatment of alternative models of information acquisition/transmission that have been advanced to rationalize price dispersion in online and offline markets for homogeneous products. These different frameworks -- which include sequential search, fixed sample search, and clearinghouse models -- reveal that reductions in (or the elimination of) consumer search costs need not reduce (or eliminate) price dispersion. Our treatment highlights a "duality" between search-theoretic and clearinghouse models of dispersion, and shows how auction-theoretic tools may be used to simplify (and even generalize) existing theoretical results. We conclude with an overview of the burgeoning empirical literature. The empirical evidence suggests that price dispersion in both online and offline markets is sizeable, pervasive, and persistent and does not purely stem from subtle differences in firms' products or services.
Proteomic analysis of a penicillin-tolerant rgg mutant strain of Streptococcus pyogenes.

OBJECTIVES To determine whether the transcriptional regulator Rgg contributes to penicillin-induced killing of Streptococcus pyogenes by altering a regulatory response to penicillin. METHODS Penicillin-induced killing of a wild-type and isogenic rgg mutant strain was assessed in broth and solid media and in the presence of cerulenin, which inhibits fatty acid biosynthesis (FAB). Proteins from wild-type and rgg mutant cultures, either exposed to penicillin or not, were characterized by two-dimensional gel electrophoresis. Proteins of interest were identified with tandem mass spectrometry. RESULTS The MIC of penicillin was 0.012 mg/L for both the wild-type strain NZ131 and an isogenic rgg mutant strain. The wild-type strain lost 1.9 log(10) cfu/mL ( approximately 80-fold) after 24 h of exposure to 0.024 mg/L penicillin compared with controls; however, the mutant strain lost 0.3 log(10) cfu/mL ( approximately 2-fold) compared with controls. Changes in the proteome of wild-type and mutant cultures were assessed 1 and 4 h after exposure to penicillin. One hour exposure was associated with increased abundance (P < 0.05) of 12 proteins associated with FAB, the pentose phosphate pathway, glycolysis and stress responses in the wild-type strain. The abundance of 8 of 12 of these proteins was greater in samples obtained from the mutant strain, even prior to penicillin exposure. After 4 h of exposure, the abundance of 16 proteins was altered in one or both strains; however, a clear functional relationship was not evident. The addition of cerulenin slightly enhanced penicillin-induced killing of wild-type strain, which supported the proteomic results. CONCLUSIONS The results suggest that penicillin-independent changes in the cytoplasmic proteome of an rgg mutant strain of NZ131 confer tolerance to penicillin-mediated killing.
