How do children make sense of their experiences? Children’s memories of wellbeing and distress from an attachment perspective

Attachment’s role in children’s memories of wellbeing and distress was evaluated through the Manchester Child Attachment Story Task in 30 Italian children, aged 6 years (15 secure and 15 insecure). Their mothers’ coherence of discourse was determined using the Adult Attachment Interview. A mediation model examining whether children’s attachment mediated the relation between mothers’ ability to talk coherently about their past and children’s memories was tested. Children’s attachment was associated with their ability to describe memories of wellbeing and distress and mediated the influence of maternal coherence on the same ability. A regression model was estimated to further evaluate the association between children’s attachment and ability to describe memories. Results suggest that attachment influences how children understand and recollect emotional experiences.
A CLOSER VIEW OF THE RADIO–FIR CORRELATION: DISENTANGLING THE CONTRIBUTIONS OF STAR FORMATION AND ACTIVE GALACTIC NUCLEUS ACTIVITY

We extend the Unified Radio Catalog, a catalog of sources detected by various (NVSS, FIRST, WENSS, GB6) radio surveys, and SDSS, to IR wavelengths by matching it to the IRAS Point and Faint Source catalogs. By fitting each NVSS-selected galaxy's NUV-NIR spectral energy distribution (SED) with stellar population synthesis models we add to the catalog star formation rates (SFRs), stellar masses, and attenuations. We further add information about optical emission-line properties for NVSS-selected galaxies with available SDSS spectroscopy. Using an NVSS 20 cm (F1.4 GHz ≳ 2.5 mJy) selected sample, matched to the SDSS spectroscopic (“main” galaxy and quasar) catalogs and IRAS data (0.04 < z ≲ 0.2) we perform an in-depth analysis of the radio–FIR correlation for various types of galaxies, separated into (1) quasars, (2) star-forming, (3) composite, (4) Seyfert, (5) LINER, and (6) absorption line galaxies using the standard optical spectroscopic diagnostic tools. We utilize SED-based SFRs to independently quantify the source of radio and FIR emission in our galaxies. Our results show that Seyfert galaxies have FIR/radio ratios lower than, but still within the scatter of, the canonical value due to an additional (likely active galactic nucleus (AGN)) contribution to their radio continuum emission. Furthermore, IR-detected absorption and LINER galaxies are on average strongly dominated by AGN activity in both their FIR and radio emission; however their average FIR/radio ratio is consistent with that expected for star-forming galaxies. In summary, we find that most AGN-containing galaxies in our NVSS–IRAS–SDSS sample have FIR/radio flux ratios indistinguishable from those of the star-forming galaxies that define the radio–FIR correlation. Thus, attempts to separate AGNs from star-forming galaxies by their FIR/radio flux ratios alone can separate only a small fraction of the AGNs, such as the radio-loud quasars.
On Translational Language Competence

AbstractThis paper presents some of the results from the empirical studies carried out for a research project on translation proficiency. Data were collected from interviews with Chinese/English translators in Australia. The investigation focuses on translational language competence of translators. It identifies translational language competence as one of the components of translation proficiency. It holds that the high level of language competence of both the SL and TL, equivalent to university educated language user is an essential requirement of any translator. It argues that the language competence of translators in both the first and foreign language should be emphasised.ResumeCet article presente des resultats d'etudes empiriques menees dans le cadre d'un projet de recherche sur la competence en matiere de traduction.

QuickRank: a C++ Suite of Learning to Rank Algorithms

Ranking is a central task of many Information Retrieval (IR) problems, particularly challenging in the case of large-scale Web collections where it involves effectiveness requirements and effciency constraints that are not common to other ranking-based applications. This paper describes QuickRank, a C++ suite of effcient and effective Learning to Rank (LtR) algorithms that allows high-quality ranking functions to be devised from possibly huge training datasets. QuickRank is a project with a double goal: i) answering industrial need of Tiscali S.p.A. for a exible and scalable LtR solution for learning ranking models from huge training datasets; ii) providing the IR research community with a exible, extensible and effcient LtR framework to design LtR solutions and fairly compare the performance of different algorithms and ranking models. This paper presents our choices in designing QuickRank and report some preliminary use experiences.
Glucose metabolism and neurogenesis in the gerbil hippocampus after transient forebrain ischemia

Recent evidence exists that glucose transporter 3 (GLUT3) plays an important role in the energy metabolism in the brain. Most previous studies have been conducted using focal or hypoxic ischemia models and have focused on changes in GLUT3 expression based on protein and mRNA levels rather than tissue levels. In the present study, we observed change in GLUT3 immunoreactivity in the adult gerbil hippocampus at various time points after 5 minutes of transient forebrain ischemia. In the sham-operated group, GLUT3 immunoreactivity in the hippocampal CA1 region was weak, in the pyramidal cells of the CA1 region increased in a time-dependent fashion 24 hours after ischemia, and in the hippocampal CA1 region decreased significantly between 2 and 5 days after ischemia, with high level of GLUT3 immunoreactivity observed in the CA1 region 10 days after ischemia. In a double immunofluorescence study using GLUT3 and glial-fibrillary acidic protein (GFAP), we observed strong GLUT3 immunoreactivity in the astrocytes. GLUT3 immunoreactivity increased after ischemia and peaked 7 days in the dentate gyrus after ischemia/reperfusion. In a double immunofluorescence study using GLUT3 and doublecortin (DCX), we observed low level of GLUT3 immunoreactivity in the differentiated neuroblasts of the subgranular zone of the dentate gyrus after ischemia. GLUT3 immunoreactivity in the sham-operated group was mainly detected in the subgranular zone of the dentate gyrus. These results suggest that the increase in GLUT3 immunoreactivity may be a compensatory mechanism to modulate glucose level in the hippocampal CA1 region and to promote adult neurogenesis in the dentate gyrus.
A study of phase noise in CMOS oscillators

This paper presents a study of phase noise in two inductorless CMOS oscillators. First-order analysis of a linear oscillatory system leads to a noise shaping function and a new definition of Q. A linear model of CMOS ring oscillators is used to calculate their phase noise, and three phase noise phenomena, namely, additive noise, high-frequency multiplicative noise, and low-frequency multiplicative noise, are identified and formulated. Based on the same concepts, a CMOS relaxation oscillator is also analyzed. Issues and techniques related to simulation of noise in the time domain are described, and two prototypes fabricated in a 0.5-/spl mu/m CMOS technology are used to investigate the accuracy of the theoretical predictions. Compared with the measured results, the calculated phase noise values of a 2-GHz ring oscillator and a 900-MHz relaxation oscillator at 5 MHz offset have an error of approximately 4 dB.
Some Crossand Intracultural Comparisons of Expressed Values of Arab and American College Students

Comparisons of expressed values were made between Arab and American university students, and between groups within the Arab sample. The values expressed consisted of ratings of 55 statements representing situations commonly thought to involve morality. The Arab-American comparisons yielded significant differences between the median ratings on 21 of the 55 items. The large differences occurred in unexpected areas, whereas the expected differences tended to be small. Overall, the obtained expressed values of the Eastern and Western students were similar both in terms of general level of severity and the rankings of the situations presented. The intra-Arab (Moslem-Christian and malefemale) comparisons produced few significant differences. A systematic interpretation of the obtained differences between Moslems and Christians was not evident, while the males and females differed primarily on questions involving sexual behavior. The purpose of this study was to compare the expressed values of Arab and American college students, and to make some comparisons within the Arab sample. The Arab students were attending the American University of Beirut in Lebanon, and the Americans were obtained from Memphis State University, Memphis, Tennessee. Both samples were secured primarily from undergraduate psychology courses. Among the topics discussed by Pittel and Mendelsohn (1966) in their review of the measurement of moral values was that of the intention of the investigator in measuring values. They listed individual assessment, prediction of moral behavior, development of moral values and the comparison of groups with respect to position on various moral issues. It was the last of these aims wxhi ch m ot iv ated thi s study.
A Hybrid CPU+GPU Working-Set Dictionary

In this paper, we propose a hybrid CPU+GPU data structure, that optimizes search operation for frequently accessed search keys. This is based on the working-set structure due to Badiu et al. [1]. The main idea is to maintain a dynamic set of most frequently accessed keys in the GPU memory and the rest of the keys in the CPU main memory. Further, search queries are processed in batches of size 1K to 16K (K = 210). We measured the query throughput of our data structure using Millions of Queries Processed per Second (MQPS) as a metric, on different key access distributions. On distributions, where some keys are accessed more frequently than others, we achieved 2x higher MQPS when compared to a highly tuned hash map provided by C++ BOOST library, and 1.5x higher MQPS against the B+ tree implementation in the Rodinia GPU benchmark. We further showed the effectiveness of our structure, when it is used to store visited vertices information in breadth-first search traversal of graphs. Here, we achieved 1.2x and 1.5x speedups when compared to the BOOST hash map and the GPU B+ trees respectively.
Is there a place for role theory in occupational science

Abstract This article, the second in a two‐part series, builds upon Contemporary Criticisms of Role Theory. The usefulness of role theory for occupational science is questioned through examining the compatibility between role theory and the underlying assumptions of occupational science. It is suggested that whereas role was an organizing structure in occupational behavior, upon which occupational scientists at University of Southern California drew their initial concepts, occupation has become the focus of concern in occupational science. DeVault's study, Feeding the Family, is used to explicate the depth of information one can gather when using an occupation‐centered analysis. Such insights include the diverse ways people enact and infuse meaning into their occupations; how race, class, age, ethnicity, and sexual orientation contribute to the form, process, context, and meaning of occupation; the influences of local and global environments depicted in policies and ideologies about occupations; and the n.
Black Male-Black Female Relationships: The Perceptions of 155 Middle-Class Black Men.

One hundred and fifty-five middle-class black men were surveyed through questionnaires to obtain data on their perceptions of key issues related to problems affecting black male-black female relationships. A majority of these men reported that black women had more opportunity than black men, and a large minority felt that black women were, in part at least, responsible for the relative low status of black men. Those respondents who had a pessismistic view of black male-black female relationships also tended to feel that they had been affected little by racial discrimination, and preferred traditional gender roles for men and women. It was concluded that salient issues affecting black male-black female relationships may vary by socio-economic status, political and ideological orientations, and the overall social circumstances experienced by black men and black women during any given historical period.
Metabolic test with fluorine-18-fluorodeoxyglucose in staging and detection of residual tumor or recurrence in Hodgkin lymphoma.

OBJECTIVE The metabolic test using 18F-fluorodeoxyglucose is a useful tool for the management of patients with Hodgkin lymphoma, either for staging purposes or for the evaluation of suspicious masses that can frequently occur after treatment. The aim of the present study was to investigate the value of the 18F-fluorodeoxyglucose test performed with a dual-head coincident gamma camera (CGC-PET with fluorodeoxyglucose) for the staging and the detection of residual tumor of patients with Hodgkin lymphoma. METHODS Thirty-eight consecutive patients were included in this retrospective study; the metabolic test comprising CGC-PET with FDG was done in 18 patients for staging work-up (Group 1), and the results were compared to conventional clinical staging procedures that included computed tomography scans and bone marrow biopsy. The remaining 20 patients were evaluated with CGC-PET with fluorodeoxyglucose due to the presence of residual masses or a new lesion (Group 2). RESULTS The 18F-Fluorodeoxyglucose metabolic test, CGC-PET with fluorodeoxyglucose, upstaged 5 (27%) of the Group 1 patients and detected more lesions (45) than conventional methods of staging (33). Of the 20 patients in Group 2, 11 had positive18F-fluorodeoxyglucosetests, and a viable tumor was confirmed in 9 patients. Regarding the 9 patients with negative fluorodeoxyglucose metabolic tests, the 1-year probability of recurrence was 11.8%. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the CGC-PET with fluorodeoxyglucose test were 90%, 80%, 82%, 89%, and 85% respectively. CONCLUSIONS The metabolic test comprising CGC-PET with fluorodeoxyglucose had a higher diagnostic accuracy than conventional methods in the staging of Hodgkin lymphoma and thus is a valuable noninvasive tool for the diagnosis of suspicious lesions.
Rhetoric, Dialectic, and Logic as Related to Argument

This article challenges the view that rhetoric, dialectic and logic are three perspectives on argument, relating respectively to its process, its procedure, and its product. It also questions the view that rhetorical arguments represent a distinctive type. It suggests that, as related to argument, rhetoric is the theory of arguments in speeches, dialectics the theory of arguments in conversations, and logic the theory of good reasoning in each.
Mitochondrial-Dependent Ca2+ Handling in Huntington's Disease Striatal Cells: Effect of Histone Deacetylase Inhibitors

Evidence suggests that neuronal dysfunction in Huntington's disease (HD) striatum involves deficits in mitochondrial function and in Ca2+ handling. However, the relationship between mitochondria and Ca2+ handling has been incompletely studied in intact HD striatal cells. Treatment with histone deacetylase (HDAC) inhibitors reduces cell death in HD models, but the effects of this promising therapy on cellular function are mostly unknown. Here, we use real-time functional imaging of intracellular Ca2+ and mitochondrial membrane potential to explore the role of in situ HD mitochondria in Ca2+ handling. Immortalized striatal (STHdh) cells and striatal neurons from transgenic mice, expressing full-length mutant huntingtin (Htt), were used to model HD. We show that (1) active glycolysis in STHdh cells occludes the mitochondrial role in Ca2+ handling as well as the effects of mitochondrial inhibitors, (2) STHdh cells and striatal neurons in the absence of glycolysis are critically dependent on oxidative phosphorylation for energy-dependent Ca2+ handling, (3) expression of full-length mutant Htt is associated with deficits in mitochondrial-dependent Ca2+ handling that can be ameliorated by treatment with HDAC inhibitors (treatment with trichostatin A or sodium butyrate decreases the proportion of STHdh cells losing Ca2+ homeostasis after Ca2+-ionophore challenging, and accelerates the restoration of intracellular Ca2+ in striatal neurons challenged with NMDA), and (4) neurons with different response patterns to NMDA receptor activation exhibit different average somatic areas and are differentially affected by treatment with HDAC inhibitors, suggesting subpopulation or functional state specificity. These findings indicate that neuroprotection induced by HDAC inhibitors involves more efficient Ca2+ handling, thus improving the neuronal ability to cope with excitotoxic stimuli.
Engineering craniofacial scaffolds.

OBJECTIVE To develop an integrated approach for engineering craniofacial scaffolds and to demonstrate that these engineered scaffolds would have mechanical properties in the range of craniofacial tissue and support bone regeneration for craniofacial reconstruction. EXPERIMENTAL VARIABLE Scaffold architecture designed to achieve desired elasticity and permeability. Scaffold external shape designed to match craniofacial anatomy. OUTCOME MEASURE Final fabricated biomaterial scaffolds. Compressive mechanical modulus and strength. Bone regeneration as measured by micro-CT scanning, mechanical testing and histology. SETTING Departments of Biomedical Engineering, Oral/Maxillofacial Surgery, and Oral Medicine, Pathology and Oncology at the University of Michigan. RESULTS Results showed that the design/fabrication approach could create scaffolds with designed porous architecture to match craniofacial anatomy. These scaffolds could be fabricated from a wide range of biomaterials, including titanium, degradable polymers, and degradable calcium phosphate ceramics. Mechanical tests showed that fabricated scaffolds had compressive modulus ranging 50 to 2900 MPa and compressive strength ranging from 2 to over 56 MPa, within the range of human craniofacial trabecular bone. In vivo testing of designed scaffolds showed that they could support bone regeneration via delivery of BMP-7 transduced human gingival fibroblasts in a mouse model. Designed hydroxyapatite scaffolds with pore diameters ranging from 400 to 1200 microns were implanted in minipig mandibular defects for 6 and 18 weeks. Results showed substantial bone ingrowth (between 40 and 50% at 6 weeks, between 70 and 80% at 18 weeks) for all scaffolds, with no significant difference based on pore diameter. CONCLUSION Integrated image-based design and solid free-form fabrication can create scaffolds that attain desired elasticity and permeability while fitting any 3D craniofacial defect. The scaffolds could be manufactured from degradable polymers, calcium phosphate ceramics and titanium. The designed scaffolds supported significant bone regeneration for all pore sizes ranging from 300 to 1200 microns. These results suggest that designed scaffolds are clinically applicable for complex craniofacial reconstruction.
Repositório ISCTE-IUL

Two studies examined the effect of exposure to sexism on implicit gender bias, focusing specifically on stereotypes of men as competent and women as warm. Male and female participants were exposed to sexism or no-sexism. In both Experiment 1 (Implicit Association Task; N = 115) and Experiment 2 (Go/No-go Association Task; N = 167), women who had been exposed to sexist beliefs demonstrated less implicit gender stereotype bias relative to women who were not exposed to sexism. In contrast, exposure to sexism did not influence men’s implicit gender stereotype bias. In Experiment 2, process modelling revealed that women’s reduction in bias in response to sexism was related to increased accuracy-orientation and a tendency to make warmth versus competence judgments. The implications of these findings for current understandings of sexism and its effects on gender stereotypes are discussed.
Contamination and Sensitivity Issues with a Real-Time Universal 16S rRNA PCR

ABSTRACT A set of universal oligonucleotide primers specific for the conserved regions of the eubacterial 16S rRNA gene was designed for use with the real-time PCR Applied Biosystems 7700 (TaqMan) system. During the development of this PCR, problems were noted with the use of this gene as an amplification target. Contamination of reagents with bacterial DNA was a major problem exacerbated by the highly sensitive nature of the real-time PCR chemistry. This was compounded by the use of a small amplicon of approximately 100 bases, as is necessary with TaqMan chemistry. In an attempt to overcome this problem, several methodologies were applied. Certain treatments were more effective than others in eliminating the contaminating DNA; however, to achieve this there was a decrease in sensitivity. With UV irradiation there was a 4-log reduction in PCR sensitivity, with 8-methoxypsoralen activity facilitated by UV there was between a 5- and a 7-log reduction, and with DNase alone and in combination with restriction digestion there was a 1.66-log reduction. Restriction endonuclease treatment singly and together did not reduce the level of contaminating DNA. Without the development of ultrapure Taq DNA polymerase, ultrapure reagents, and plasticware guaranteed to be free of DNA, the implementation of a PCR for detection of eubacterial 16S rRNA with the TaqMan system will continue to be problematical.
Examining interaction in the teaching practicum: issues of language, power and control

This study examines the post‐observation interactions between six English as a Second Language (ESL) student teachers and their university tutors during their teaching practicum in Hong Kong. Data consist of interviews with university tutors, transcriptions of recorded conferences and stimulated recall interviews with student teachers. Case studies of two student teachers are used to examine the impact of the tutors' feedback and to highlight the way that the student teachers' response is affected by the power relations involved in the dialogue. The article also considers some areas in which miscommunication occurred between tutors and student teachers and discusses possible reasons for this.
