  1. Attachment of cells to basement membrane collagen type IV

    OpenAIRE

    1986-01-01

    Of ten different cell lines examined, three showed distinct attachment and spreading on collagen IV substrates, and neither attachment nor spreading was enhanced by adding soluble laminin or fibronectin. This reaction was not inhibited by cycloheximide or antibodies to laminin, indicating a direct attachment to collagen IV without the need of mediator proteins. Cell-binding sites were localized to the major triple-helical domain of collagen IV and required an intact triple helical conformatio...

    The effect of phorbol esters on the adhesive properties of NIH/3T3 mouse fibroblasts was investigated using plastic substrates precoated with the extracellular matrix proteins fibronectin, collagen, and laminin. Treatment with phorbol 12-myristate 13-acetate (PMA) enhanced NIH/3T3 cell attachment to laminin and type IV collagen substrates but had little or no effect on attachment to fibronectin and type I collagen substrates. The effect of PMA in enhancing cell attachment to laminin and type IV collagen substrates was dose dependent between 10{sup {minus}9} and 10{sup {minus}7} M. PMA was effective as early as 30 min; the effect reached a maximum at 2 h and decreased gradually. Phorbol 12, 13-dibenzoate and phorbol 12, 13-diacetate were effective but to a lesser extent and phorbol 12-myristate and phorbol 13-acetate showed little or no effect. These results suggest that PMA may enhance NIH/3T3 cell adhesion through effects on laminin and type IV collagen receptors. Retinoic acid, which itself requires at least 6 h to show an effect on attachment, did not have any effect on cell attachment in 2 h and, if anything, slightly inhibited PMA-enhanced cell attachment to laminin and type IV collagen substrates.

    In this study, we evaluated complex patterns of attachment discontinuity across time in 133 individuals from the Minnesota Study of Risk and Adaptation. In addition to individuals who were either insecure or secure across infancy, late adolescence, and adulthood (Stably Insecure and Stably Secure, respectively), we found three additional groups: Infant/Adolescent Secure, Infant/Adult Secure, and Infant-only Secure. Changes in attachment representations in these groups across time corresponded to stresses and supports in the socio-emotional context. The two groups classified as secure in adulthood (Stably Secure and Infant/Adult Secure) experienced more positive relationship-based outcomes than the other three groups. Our results suggest that continuity may be a reflection of a stable social context as much as it is an artifact of early working models, and illustrate "homeorhetic" pathways of development, in which not only the direction but the length of a developmental pathway can constrain future developmental trajectories.

    Adolescent attachment to formal and informal institutions has emerged as a major focus of criminological theories since the publication of Hirschi's work in 1969. This study attempts to examine the psychometric equivalence of the factorial structure of attachment measures across nations reflecting Western and Eastern cultures. Twelve manifest variables are used tapping the concepts of adolescent attachment to parents, school, and neighborhood. Confirmatory factor analysis is used to conduct invariance test across approximately 3,000 Chinese and U.S. adolescents. Results provide strong support for a three-factor model; the multigroup invariance tests reveal mixed results. While the family attachment measure appears invariant between the two samples, significant differences in the coefficients of the factor loadings are detected in the school attachment and neighborhood attachment measures. The results of regression analyses lend support to the predictive validity of three types of attachment. Finally, the limitations of the study are discussed.

    Modified polystyrene with Pt(IV)–azomethine (APS–Sch–Pt) was synthesized by means of condensation and demonstrated to be a promising enzyme support by studying the enzymatic properties of glucose oxidase enzyme (GOx) immobilized on it. The characteristics of the immobilized glucose oxidase (APS–Sch–Pt–GOx) enzyme showed two optimum pH values that were pH = 4.0 and pH = 7. The insertion of stable Pt(IV)–azomethine spacers between the polystyrene backbone and the immobilized GOx, (APS–Sch–Pt–GOx), increases the enzymes’ activity and improves their affinity towards the substrate even at pH = 4. The influence of temperature, reusability and storage capacity on the free and immobilized glucose oxidase enzyme was investigated. The storage stability of the immobilized glucose oxidase was shown to be eleven months in dry conditions at +4 °C. PMID:23109888

    In this attachment to the Annual report 1999 of the Nuclear Regulatory Authority of the Slovak Republic (UJD) the economic and personnel data of the UJD, used abbreviations, as well as the International nuclear event scales - INES are presented. Professional level of staff of the UJD is influenced by the education structure of its staff, when nearly 75% of the total number of staff has a university degree. A of 31.12.1999 there were 79 employees as average calculated number. Financing of the regulator in 1999 was mainly provided from the state budget, which represented 96% of all expenditures. The total volume of expenditures for UJD activity funded from the state budget achieved as of 31.12.1999 Slovak crowns (SK) 67 067 thousands. In the main category of expenditures an amount of SK 63 499 thous. was used for current activities, and the difference of SK 3 587 thous. was used for raising capital assets. Significant increase expenditures in the evaluated year compared to the 1998 was caused by a special purpose payment made by the Slovakia into the Fund for reconstruction of the Chernobyl cover (SK 19 996 thous.) funded through the budget chapter of the regulator. In the structure of current expenditures the highest share is taken by current transfers to abroad in total of SK 22 543 thous., i.e. contribution to reconstruction of Chernobyl cover made to the EBRD and contributions to the Fund of Technical Co-operation of the IAEA. For procurement of goods and services an amount of SK 19 814 thous. was spent, of which SK 7 054 thous. was used for funding science and technology tasks which were contracted out. The decision-making process in performing state supervision forced UJD to contact out various expert opinions and studies, for which UJD paid SK 2 058 thous. in total. Other expenditures in a volume of SK 10 702 thous. represent travel expenses, goods and services for UJD, rent for offices and other inevitable expenses. Salaries of staff represented SK 15 953

    In contrast with traumatic experiences, there is a dearth of studies on the link between trauma symptoms, disconnected (frightened, threatening and dissociative) parenting behavior, extremely insensitive parenting behavior and child attachment. This study extends previous work on the impact of posttraumatic stress disorder (PTSD) on families by studying the unique contribution of disconnected and extremely insensitive parenting behavior on child attachment in a highly traumatized sample of 68 asylum seekers and refugees and their children (18-42 months). The results show that parental symptoms of PTSD are directly related to children's insecure attachment and disorganized attachment. The greatest proportion of the risk could be attributed to factors related to the dyad and not the family. A mediation effect of adverse parenting behavior was not confirmed. On the one hand the results indicate the need for an effective treatment of PTSD symptomatology while on the other hand the results indicate the need for clinical attention to insecure attachment relationships.

    The interaction between PTCDA (3,4,9,10-perylene-tetracarboxylic-dianhydride) and rare gas or para-hydrogen samples is studied by means of laser-induced fluorescence excitation spectroscopy. The comparison between spectra of PTCDA embedded in a neon matrix and spectra attached to large neon clusters shows that these large organic molecules reside on the surface of the clusters when doped by the pick-up technique. PTCDA molecules can adopt different conformations when attached to argon, neon and para-hydrogen clusters which implies that the surface of such clusters has a well-defined structure and has not liquid or fluxional properties. Moreover, a precise analysis of the doping process of these clusters reveals that the mobility of large molecules on the cluster surface is quenched, preventing agglomeration and complex formation.

    The widespread use of organophosphate pesticides (OPPs) in agriculture leads to residue accumulation in the environment which is dangerous to human health and disrupts the ecological balance. In this work, one nanocomposite immobilized zirconium (Zr, IV) was prepared and used as the affinity probes to quickly and selectively extract organophosphorus pesticides (OPPs) from water samples. The Fe3O4-ethylenediamine tetraacetic acid (EDTA)@Zr(IV) nanocomposites (NPs) were prepared by simply mixing Zr(IV) ions with Fe3O4-EDTA NPs synthesized by one-pot chemical co-precipitation method. The immobilized Zr(IV) ions were further utilized to capture OPPs based on their high affinity for the phosphate moiety in OPPs. Coupled with GC-MS, four OPPs were used as models to demonstrate the feasibility of this approach. Under the optimum conditions, the limits of detection for target OPPs were in the range of 0.10-10.30ngmL(-1) with relative standard deviations (RSDs) of 0.61-4.40% (n=3), respectively. The linear ranges were over three orders of magnitudes (correlation coefficients, R(2)>0.9995). The Fe3O4-EDTA@Zr(IV) NPs were successfully applied to extract OPPs samples with recoveries of 86.95-112.60% and RSDs of 1.20-10.42% (n=3) from two spiked real water. By the proposed method, the matrix interference could be effectively eliminated. We hope our finding can provide a promising alternative for the fast extraction of OPPs from complex real samples.

    This study examined the role of adult attachment and personality in relation to antisocial tendencies (i.e. convictions for violence and interpersonal problems in romantic relationships) in Norwegian prison inmates (N=92). Attachment styles and personality were measured using self-report questionnaires (RSQ; Griffin & Bartholomew, 1994; and NEO-FFI, Costa & McCrae, 1992a). The prison inmates scored higher on avoidant than on anxious attachment style. While age and agreeableness (negatively associated) emerged as significant predictors of violence, anxious attachment explained most of the variances in aggression in intimate relationships. The study suggests that different types of antisocial tendencies could have different attachment and general personality correlates.

    STEEP(TM) was one of the first attachment-based early intervention programs. The program applied findings from the Minnesota Longitudinal Study on Risk and Adaptation to the development of a supportive program for young high-risk mothers and their infants. STEEP's effectiveness was evaluated first in a randomized controlled study launched in 1987. The study showed effects of the one-year intervention on important individual and parenting variables, but not on quality of mother-infant attachment. In the current German study with young mothers at risk for abuse and neglect, a two-year adaptation of STEEP was evaluated within a quasi-experimental design. STEEP mother-infant pairs (N = 78) were compared with pairs who received standard services of the German Child Welfare System (GCWS, N = 29). Compared with GCWS pairs, significantly more mother-infant pairs in the intervention group showed secure attachment patterns in Ainsworth´s Strange Situation when the infants were 12 months of age. At the end of the intervention (infant age = 24 month), attachment security scores derived from Waters' Attachment Q-Sort were in the predicted direction and showed a medium effect size, but did not reach criteria of statistical significance. At both time points, the STEEP group showed significantly fewer signs of attachment disorganization than the comparison group.

The participants were 308 university students from Malaysia. A demographic questionnaire and three self-report inventories were administrated in this study. The data indicated that the Relationship Scales Questionnaire (RSQ is a multidimensional construct with nine factors: “dismissing,” “preoccupied with romance,” “preoccupied with close relationships,” “fearful,” “preoccupied with dependency,” “secure emotional,” ”comfortable depending,” “preoccupied with mistrust” and “mutual secure.” Different attachment styles were positively or negatively correlated at a significant level with perceived stress and social support. Attachment styles were explained by 20 and 33% of the total variance in self-perceived stress and perceived social support, respectively. There were significant gender, ethnic and religious differences in attachment styles, perceived stress and social support.

    Activity concentrations and distributions of natural and man-made radionuclides in soil samples collected around nuclear power plant IV, Taiwan, were investigated for five years to assess the environmental radioactivity and characterisation of radiological hazard prior to commercial operation. The activity concentrations of radionuclides were determined via gamma-ray spectrometry using an HPGe detector. Data obtained show that the average concentrations of the (238)U and (232)Th series, and (40)K, were within world median ranges in the UNSCEAR report. The (137)Cs ranged from 2.46 +/- 0.55 to 12.13 +/- 1.31 Bq kg(-1). The terrestrial absorbed dose rate estimated by soil activity and directly measured with a thermoluminescence dosemeter (excluding cosmic rays), and the annual effective doses, were 45.63, 57.34 nGy h(-1) and 57.19 microSv, respectively. Experimental results were compared with international recommended values. Since the soil in this area is an important building material, the mean radium equivalent activity, external and inhalation hazard indices and the representative level index using various models given in the literature for the study area were 98.18 Bq kg(-1), 0.27, 0.34 and 0.73, respectively, which were below the recommended limits. Analytical results demonstrate that no radiological anomaly exists. The baseline data will prove useful and important in estimating the collective dose near the new nuclear power plant under construction in Taiwan. PMID:18714131

    Full Text Available Objective: The present study aimed at investigating the differences between nonclinical sample and clinical sample (OCD patients in attachment, obsessive beliefs and emotion regulation in Turkish sample. Methods: For these purposes 224 non clinical participants and 101 clinical OCD participants completed questionnaires related to research variables. Experience in Close Relationship Scale (Fraley, Waller & Brennan, 2000 to evaluate attachment, Obsessive Belief Questionnaire to evaluate obsessive beliefs and Difficulties of Emotion Regulation Scale (Gratz & Roemer, 2004 to evaluate emotion regulation abilities were used in this study. Results: A series of t-test for independent samples analyses were done. Findings of the analyses revealed that there was significant differences between two groups in anxiety level of attachment, but not in avoidance level. Also there were significant differences between two groups in all obsessive beliefs subscales such as responsibility and threat perception, perfectionism and need of certainty, the importance of thoughts and control. From emotional regulation perspective there were significant differences in non-acceptance of emotional response, difficulties in engaging goal-directed behavior, impulse control difficulties during emotional distress, limited access to emotional regulation strategies. However there was not significant differences between two groups in clarity about emotions and awareness of emotional arousal. Conclusion: To sum up according to results of this study attachment and obsessive beliefs follow the same pattern with the results in the literature. Moreover the difficulties of emotion regulation abilities thought to improve the knowledge about OCD. Because this part believed not to have enough findings in the OCD literature. The results were discussed in the light of the related literature and dependent recommendations to the area were given.

    This Sampling and Analysis Plan (SAP) is written for the radiological environmental air surveillance program for the DOE-SC PNNL Site, Richland Washington. It provides the requirements for planning sampling events, and the requirements imposed on the analytical laboratory analyzing the air samples. The actual air sampling process is in procedure EPRP-AIR-029. The rationale for analyte selection, media, and sampling site location has been vetted through the data quality objectives (DQO) process (Barnett et al. 2010). The results from the DQO process have been reviewed and approved by the Washington State Department of Health. The DQO process (Barnett et al. 2010) identified seven specific radionuclides for analysis along with the need for gross alpha and gross beta radiological analyses. The analytes are {sup 241}Am, {sup 243}Am, {sup 244}Cm, {sup 60}Co, {sup 238}Pu, {sup 239}Pu, and {sup 233}U. The report also determined that air samples for particulates are the only sample matrix required for the monitoring program. These samples are collected on 47-mm glass-fiber filters.

    The interaction between PTCDA (3,4,9,10-perylene-tetracarboxylic-dianhydride) molecules and solid rare gas samples is studied by means of fluorescence emission spectroscopy. On the one hand, laser-excited PTCDA-doped large argon, neon and para-hydrogen clusters in comparison with PTCDA embedded in helium nanodroplets are spectroscopically characterized with respect to line broadening and shifting. A fast non-radiative relaxation is observed before a radiative decay in the electronic ground state takes place. On the other hand, fluorescence emission studies of PTCDA embedded in bulk neon and argon matrices results in much more complex spectral signatures characterized by a splitting of the different emission lines. These can be assigned to the appearance of site isomers of the surrounding matrix lattice structure.

  17. PLANETARY CANDIDATES OBSERVED BY KEPLER IV: PLANET SAMPLE FROM Q1-Q8 (22 MONTHS)

    International Nuclear Information System (INIS)

    We provide updates to the Kepler planet candidate sample based upon nearly two years of high-precision photometry (i.e., Q1-Q8). From an initial list of nearly 13,400 threshold crossing events, 480 new host stars are identified from their flux time series as consistent with hosting transiting planets. Potential transit signals are subjected to further analysis using the pixel-level data, which allows background eclipsing binaries to be identified through small image position shifts during transit. We also re-evaluate Kepler Objects of Interest (KOIs) 1-1609, which were identified early in the mission, using substantially more data to test for background false positives and to find additional multiple systems. Combining the new and previous KOI samples, we provide updated parameters for 2738 Kepler planet candidates distributed across 2017 host stars. From the combined Kepler planet candidates, 472 are new from the Q1-Q8 data examined in this study. The new Kepler planet candidates represent ∼40% of the sample with R P ∼ 1 R ⊕ and represent ∼40% of the low equilibrium temperature (T eq < 300 K) sample. We review the known biases in the current sample of Kepler planet candidates relevant to evaluating planet population statistics with the current Kepler planet candidate sample

    Context. The XXL Survey is the largest survey carried out by XMM-Newton. Covering an area of 50 deg2, the survey contains ~450 galaxy clusters out to a redshift ~2 and to an X-ray flux limit of ~ 5 × 10-15 erg s-1 cm-2. This paper is part of the first release of XXL results focussed on the bright cluster sample. Aims: We investigate the scaling relation between weak-lensing mass and X-ray temperature for the brightest clusters in XXL. The scaling relation discussed in this article is used to estimate the mass of all 100 clusters in XXL-100-GC. Methods: Based on a subsample of 38 objects that lie within the intersection of the northern XXL field and the publicly available CFHTLenS shear catalog, we derive the weak-lensing mass of each system with careful considerations of the systematics. The clusters lie at 0.1 relation. Results: The mass-temperature relation fit (M ∝ Tb) to the XXL clusters returns a slope and intrinsic scatter σlnM|T≃ 0.53; the scatter is dominated by disturbed clusters. The fit to the combined sample of 96 clusters is in tension with self-similarity, b = 1.67 ± 0.12 and σlnM|T ≃ 0.41. Conclusions: Overall our results demonstrate the feasibility of ground-based weak-lensing scaling relation studies down to cool systems of ~1 keV temperature and highlight that the current data and samples are a limit to our statistical precision. As such we are unable to determine whether the validity of hydrostatic equilibrium is a function of halo mass. An enlarged sample of cool systems, deeper weak-lensing data, and robust modelling of the selection function will help to explore these issues further.

    Sintered pellets of thorium-uranium (IV) phosphate-diphosphate solid solutions ({beta}-Th{sub 4-x}U {sub x}(PO{sub 4}){sub 4}P{sub 2}O{sub 7}, {beta}-TUPD) were altered in several acidic media. All the results reported in the first part of this paper confirmed the good chemical durability of the samples. The evolution of the normalized weight loss showed that, in several media, thorium quickly precipitates in a neoformed phosphate-based phase while uranium (IV) is released in the leachate due to its oxidation into the uranyl form. The characterization of neoformed phases was carried out through several techniques involving grazing XRD, infrared and {mu}-Raman spectroscopies, EPMA, SEM and TEM. SEM micrographies showed that the dissolution mainly occurs at the grain boundaries, leading to the break away of the grains: only the first 15 {mu}m are altered for 2 months in 10{sup -1} M HNO{sub 3}. From EPMA and BET measurements, neither the chemical composition nor the specific surface area are significantly modified. Near equilibrium, two neoformed phases were observed and identified by grazing XRD and/or {mu}-Raman spectroscopy at the surface of the leached pellets: one is found to be amorphous and progressively turns into the crystallized thorium phosphate-hydrogenphosphate hydrate (TPHPH). From the results obtained, a chemical scheme of the dissolution of {beta}-TUPD sintered samples is proposed. The behavior of the actinides in the gelatinous phase appears mainly driven by their oxidation state: thorium remains in the tetrapositive state and is quickly and quantitatively precipitated while uranium (IV) is oxidized into uranyl then released in the leachate. The Th-precipitation as TPHPH first appears scattered then covers the entire surface of the pellet, inducing a delay of the actinides release in the leachate. Both phases act as protective layers and should induce the significant delay of the release of actinides (Th, U) to the biosphere.

    Context. Virialized halos grow by the accretion of smaller ones in the cold dark matter scenario. The rate of accretion depends on the different properties of the host halo. Those halos for which this accretion rate was very fast and efficient resulted in systems dominated by a central galaxy surrounded by smaller galaxies that were at least two magnitudes fainter. These galaxy systems are called fossil systems, and they can be the fossil relics of ancient galaxy structures. Aims: We started an extensive observational program to characterize a sample of 34 fossil group candidates spanning a broad range of physical properties. Methods: Deep r-band images were obtained with the 2.5-m Isaac Newton Telescope and Nordic Optic Telescope. Optical spectroscopic observations were performed at the 3.5-m Telescopio Nazionale Galileo for ~1200 galaxies. This new dataset was completed with Sloan Digital Sky Survey Data Release 7 archival data to obtain robust cluster membership and global properties of each fossil group candidate. For each system, we recomputed the magnitude gaps between the two brightest galaxies (Δm12) and the first and fourth ranked galaxies (Δm14) within 0.5 R200. We consider fossil systems to be those with Δm12 ≥ 2 mag or Δm14 ≥ 2.5 mag within the errors. Results: We find that 15 candidates turned out to be fossil systems. Their observational properties agree with those of non-fossil systems. Both follow the same correlations, but the fossil systems are always extreme cases. In particular, they host the brightest central galaxies, and the fraction of total galaxy light enclosed in the brightest group galaxy is larger in fossil than in non-fossil systems. Finally, we confirm the existence of genuine fossil clusters. Conclusions: Combining our results with others in the literature, we favor the merging scenario in which fossil systems formed from mergers of L∗ galaxies. The large magnitude gap is a consequence of the extreme merger ratio within

    In the present longitudinal study, we investigated attachment quality in Portuguese mother-infant and in father-infant dyads, and evaluated whether attachment quality was related to parental sensitivity during parent-infant social interaction or to the amount of time each parent spent with the infant during play and in routine caregiving activities (e.g., feeding, bathing, play). The sample consisted of 82 healthy full-term infants (30 girls, 53 boys, 48 first born), and their mothers and fathers from mostly middle-class households. To assess parental sensitivity, mothers and fathers were independently observed during free play interactions with their infants when infants were 9 and 15 months old. The videotaped interactions were scored by masked coders using the Crittenden's CARE-Index. When infants were 12 and 18 months old, mother-infant and father-infant dyads were videotaped during an adaptation of Ainsworth's Strange Situation. Parents also described their level of involvement in infant caregiving activities using a Portuguese version of the McBride and Mills Parent Responsibility Scale. Mothers were rated as being more sensitive than fathers during parent-infant free play at both 9 and 15 months. There also was a higher prevalence of secure attachment in mother-infant versus father-infant dyads at both 12 and 18 months. Attachment security was predicted by the amount of time mothers and fathers were involved in caregiving and play with the infant, and with parents' behavior during parent-infant free play.

    The purposes of this study were to compare DSM-IV diagnostic criteria and the Broad Categories for the Diagnosis of Eating Disorders (BCD-ED) scheme in terms of the number of cases of Eating Disorder Not Otherwise Specified (EDNOS) and to test which diagnostic tool better captures the variance of psychiatric symptoms in a Japanese sample. One thousand and twenty-nine women with an eating disorder (ED) participated in this study. Assessment methods included structured clinical interviews and administration of the Eating Attitudes Test and the Eating Disorder Inventory. The BCD-ED scheme dramatically decreased the proportion of DSM-IV EDNOS from 45.1% to 1.5%. However, the categorization of patients with the BCD-ED scheme was less able to capture the variance in psychopathology scales than the DSM-IV, suggesting that the BCD-ED scheme may differentiate ED groups less effectively than the DSM-IV. These results suggest that the BCD-ED scheme may have the potential to eliminate the use of DSM-IV EDNOS, but it may have problems capturing the variance of psychiatric symptoms.

    The interaction between 3, 4, 9, 10-perylenetetracarboxylic dianhydride (PTCDA) and rare gas or para-hydrogen samples is studied by means of laser-induced fluorescence excitation spectroscopy. The comparison between spectra of PTCDA embedded in a neon matrix and spectra attached to large neon clusters shows that these large organic molecules reside on the surface of the clusters when doped by the pick-up technique. PTCDA molecules can adopt different conformations when attached to argon, neon, and para-hydrogen clusters which implies that the surface of such clusters has a well-defined structure without liquid or fluxional properties. Moreover, a precise analysis of the doping process of these clusters reveals that the mobility of large molecules on the cluster surface is quenched, preventing agglomeration and complex formation.

    Determination of Se(IV) and Se(VI) in high saline media was investigated by cathodic stripping voltammetry (CSV). The voltammetric method was applied to assay selenium in seawater, hydrothermal and hemodialysis fluids. The influence of ionic strength on selenium determination is discussed. The CSV method was based on the co-electrodeposition of Se(IV) with Cu(II) ions and Se(VI) determined by difference after sample UV-irradiation for photolytic selenium reduction. UV-irradiation was also used as sample pre-treatment for organic matter decomposition. Detection limit of 0.030 {mu}g L{sup -1} (240 s deposition time) and relative standard deviation (RSD) of 6.19% (n = 5) for 5.0 {mu}g L{sup -1} of Se(IV) were calculated. Linear calibration range for selenium was observed from 1.0 to 100.0 {mu}g L{sup -1}. Concerning the pre-treatment step, best results were obtained by using 60 min UV-irradiation interval in H{sub 2}O{sub 2}/HCl medium. Se(VI) was reduced to the Se(IV) electroactive species with recoveries between 91.7% and 112.9%. Interferents were also investigated.

    Full Text Available Background: The World Health Organization recently proposed significant changes to the posttraumatic stress disorder (PTSD diagnostic criteria in the 11th edition of the International Classification of Diseases (ICD-11. Objective: The present study investigated the impact of these changes in two different post-conflict samples. Method: Prevalence and rates of concurrent depression and anxiety, socio-demographic characteristics, and indicators of clinical severity according to ICD-11 in 1,075 Cambodian and 453 Colombian civilians exposed to civil war and genocide were compared to those according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV. Results: Results indicated significantly lower prevalence rates under the ICD-11 proposal (8.1% Cambodian sample and 44.4% Colombian sample compared to the DSM-IV (11.2% Cambodian sample and 55.0% Colombian sample. Participants meeting a PTSD diagnosis only under the ICD-11 proposal had significantly lower rates of concurrent depression and a lower concurrent total score (depression and anxiety compared to participants meeting only DSM-IV diagnostic criteria. There were no significant differences in socio-demographic characteristics and indicators of clinical severity between these two groups. Conclusions: The lower prevalence of PTSD according to the ICD-11 proposal in our samples of persons exposed to a high number of traumatic events may counter criticism of previous PTSD classifications to overuse the PTSD diagnosis in populations exposed to extreme stressors. Also another goal, to better distinguish PTSD from comorbid disorders could be supported with our data.

    The third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III; APA, 1980) set forth a categorical system of personality psychopathology that is composed of discrete personality disorders (PDs), each with a distinct set of diagnostic criteria. Although this system is widely accepted and highly influential, alternative dimensional approaches to capturing personality psychopathology have been proposed. Three dimensional models of personality have garnered particular attention-the Five-Factor Model (FFM; Costa & McCrae, 1992), the Seven-Factor Psychobiological Model of Temperament and Character (Seven-Factor Model; Cloninger, Svrakic, & Przybeck, 1993); and the 18-factor model of personality pathology (18-factor model; Livesley, 1986). Although the personality traits from each of these models has been examined in relation to the ten personality disorders in the DSM-IV, no study has examined the comparative and incremental validity of these models in predicting PD symptoms for these ten disorders. Using self-report instruments that measure these models and the ten DSM-IV PDs, correlation and linear regression analyses indicate that traits from all three models had statistically significant associations with PD symptom counts. Hierarchical regressions revealed that the 18-factor model had incremental predictive validity over the FFM and Seven-Fac-tor Model in predicting symptom counts for all ten DSM-IV PDs. The FFM had incremental predictive validity over the Seven-Factor Model model for all ten disorders and the Seven-Factor was able to add incremental predictive validity over the 18-factor model for five of the ten PDs and for eight of the ten disorders relative to the FFM.

  20. Cloud point extraction and electrothermal atomic absorption spectrometry of Se (IV)-3,3'-Diaminobenzidine for the estimation of trace amounts of Se (IV) and Se (VI) in environmental water samples and total selenium in animal blood and fish tissue samples

    International Nuclear Information System (INIS)

    This paper presents a method based on the cloud point extraction for the separation and preconcentration of Se (IV) and Se (VI) in environmental water samples as well as total selenium in animal blood and tissue samples. 3,3'-Diaminobenzidine (DAB) is a selective and sensitive reagent and is known to form an intense yellow compound piazselenol with selenium (IV). When a system consisting of sample, DAB and surfactant Triton X-114 is warmed above the cloud point of the surfactant, it was seen that the DAB-Se (IV) complex gets extracted into the surfactant rich phase while the Se (VI) remains in the aqueous phase. Se (VI) in the sample was reduced to Se (IV) by microwave heating of solution in 4 mol L-1 HCl and total Se was estimated by carrying out the CPE. The quantification of selenium was carried out using ETAAS. The analytical parameters for the quantitative cloud point extraction of the Se-DAB complex were investigated and optimized. The proposed procedure was validated by applying it to the determination of the content of Se in Certified Reference Material BND 701-02. (NPL, India). The detection limit of selenium in environmental water samples was 0.0025 μg L-1 with an enrichment factor of 100. The relative standard deviation (RSD) for ten replicate measurements of 5 μg L-1 was 3.6%. The proposed method was successfully applied to the determination of selenium (IV), (VI) in environmental water samples and determination of total selenium in human blood, SRM-IAEA-A-13 animal blood and SRM-IAEA-407 fish tissue.

    Despite widespread use, the South Oaks Gambling Screen (SOGS) has been criticized for excessive false positives as an indicator of pathological gambling (PG), and for items that misalign with PG criteria. We examine the relationship between SOGS scores and PG symptoms and convergent validity with regard to personality, mood, and addictive behaviors in a sample of 353 gamblers. SOGS scores correlated r = .66 with both DSM-IV and DSM-5 symptoms, and they manifested similar correlations with external criteria (intraclass correlation of .95). However, 195 false positives and 1 false negative were observed when using the recommended cut point, yielding an 81% false alarm rate. For uses with DSM-IV criteria, a cut point of 10 would retain high sensitivity with greater specificity and fewer false positives. For DSM-5 criteria, we advocate a cut point of 8 for use as a clinical screen and a cut point of 12 for prevalence and pseudo-experimental studies. PMID:23946283

  3. X-ray fluorescence in Member States: Austria and Sri Lanka. A new attachment module for secondary target excitation with sample changer and vacuum chamber

    International Nuclear Information System (INIS)

    A new secondary target attachment vacuum chamber was developed, designed and constructed at the Atomic Institute of Vienna Technical University X ray Laboratory and installed at the Atomic Energy Authorities, Colombo, Sri Lanka. The prerequisites were that the new system had to fit physically next to the Wobistrax TXRF spectrometer and to use the same existing X ray tube and an existing uplooking LN2 cooled Si(Li) detector. This new spectrometer replaces a simple secondary target system previously installed. The new system offers a 10 position sample changer integrated in a vacuum chamber. The secondary targets are exchangeable, and Mo, Zr, Ti, Al, KBr and Teflon as Barkla polarizer are available. The system is designed for the emission-transmission method for quantification but can also be used for air filter samples where the thin film model for the quantification is applicable

    Since its development in the mid-1980s, the Panic Attack Questionnaire (PAQ) has been one of the more, if not the most, commonly used self-report tools for assessing panic attacks. The usage of the instrument, however, has come amid potential concerns that instructions and descriptions may lead to an over-estimate of the prevalence of panic attacks. Furthermore, the instrument has not been revised since 1992, despite changes in DSM-IV criteria and more recent developments in the understanding of panic attacks. As a result, this paper describes a revision of the PAQ to improve the instruction and descriptive set, and to fully assess features of panic derived from recent conceptualizations. Students meeting DSM-IV panic attack criteria and those endorsing panic attacks, but not meeting criteria, showed few differences with the exception that those not meeting DSM-IV criteria typically reported a longer onset-to-peak intensity time than did Panickers. Results were cross-validated and extended using an independent Community Sample. A full descriptive phenomenology of panic attacks is described, and future directions for studying panic attacks using the PAQ are presented. PMID:18243647

    The reliability and validity of three short forms of the Dutch version of the Wechsler Memory Scale-Fourth Edition (WMS-IV-NL) were evaluated in a mixed clinical sample of 235 patients. The short forms were based on the WMS-IV Flexible Approach, that is, a 3-subtest combination (Older Adult Battery for Adults) and two 2-subtest combinations (Logical Memory and Visual Reproduction and Logical Memory and Designs), which can be used to estimate the Immediate, Delayed, Auditory and Visual Memory Indices. All short forms showed good reliability coefficients. As expected, for adults (16-69 years old) the 3-subtest short form was consistently more accurate (predictive accuracy ranged from 73% to 100%) than both 2-subtest short forms (range = 61%-80%). Furthermore, for older adults (65-90 years old), the predictive accuracy of the 2-subtest short form ranged from 75% to 100%. These results suggest that caution is warranted when using the WMS-IV-NL Flexible Approach short forms to estimate all four indices.

    The current study aimed to compare the prevalence, stability, and psychosocial correlates of DSM-IV-TR and DSM-5 eating disorders, in a population-based sample of male and female adolescents followed prospectively from 14 to 20 years of age. Participants (N = 1,383; 49% male) were drawn from the Western Australian Pregnancy Cohort (Raine) Study, a prospective, population-based cohort study that has followed participants from prebirth to young adulthood. Detailed self-report questionnaires were used to assess eating disorder symptoms when participants were aged 14, 17, and 20 years. Comparisons between DSM-IV-TR and DSM-5 were conducted using McNemar chi-square tests and Fisher's exact tests. Changes in eating disorder prevalence over time were considered using generalized estimating equations. Eating disorder prevalence rates were significantly greater when using DSM-5 than DSM-IV-TR criteria, at all time points for females and at age 17 only for males. "Unspecified"/"other" eating disorder diagnoses were significantly less common when applying DSM-5 than DSM-IV-TR criteria, but still formed 15% to 30% of the DSM-5 cases. Diagnostic stability was low for all disorders, and DSM-5 binge eating disorder or purging disorder in early adolescence predicted DSM-5 bulimia nervosa in later adolescence. Cross-over from binge eating disorder to bulimia nervosa was particularly high. Regardless of the diagnostic classification system used, all eating disorder diagnoses were associated with depressive symptoms and poor mental health quality of life. These results provide further support for the clinical utility of DSM-5 eating disorder criteria, and for the significance of binge eating disorder and purging disorder.

    Full Text Available Background: This study aims to explore the frequency of aggressive behaviors among a nationally representative sample of Iranian children and adolescents. Methods: This nationwide study was performed on a multi-stage sample of 6-18 years students, living in 30 provinces in Iran. Students were asked to confidentially report the frequency of aggressive behaviors including physical fighting, bullying and being bullied in the previous 12 months, using the questionnaire of the World Health Organization Global School Health Survey. Results: In this cross-sectional study, 13,486 students completed the study (90.6% participation rate; they consisted of 49.2% girls and 75.6% urban residents. The mean age of participants was 12.47 years (95% confidence interval: 12.29, 12.65. In total, physical fight was more prevalent among boys than girls (48% vs. 31%, P < 0.001. Higher rates of involvement in two other behaviors namely being bullied and bulling to other classmates had a higher frequency among boys compared to girls (29% vs. 25%, P < 0.001 for being bullied and (20% vs. 14%, P < 0.001 for bulling to others. Physical fighting was more prevalent among rural residents (40% vs. 39%, respectively, P = 0.61, while being bullied was more common among urban students (27% vs. 26%, respectively, P = 0.69. Conclusions: Although in this study the frequency of aggressive behaviors was lower than many other populations, still these findings emphasize on the importance of designing preventive interventions that target the students, especially in early adolescence, and to increase their awareness toward aggressive behaviors. Implications for future research and aggression prevention programming are recommended.

    This paper represents a major step forward in the systematic and homogeneous study of Small Magellanic Cloud (SMC) star clusters and field stars carried out by applying the calcium triplet technique. We present in this work the radial velocity and metallicity of approximately 400 red giant stars in 15 SMC fields, with typical errors of about 7 km s-1 and 0.16 dex, respectively. We added to this information our previously determined metallicity values for 29 clusters and approximately 350 field stars using the identical techniques. Using this enlarged sample, we analyze the metallicity distribution and gradient in this galaxy. We also compare the chemical properties of the clusters and of their surrounding fields. We find a number of surprising results. While the clusters, taken as a whole, show no strong evidence for a metallicity gradient (MG), the field stars exhibit a clear negative gradient in the inner region of the SMC, consistent with the recent results of Dobbie et al. For distances to the center of the galaxy less than 4°, field stars show a considerably smaller metallicity dispersion than that of the clusters. However, in the external SMC regions, clusters and field stars exhibit similar metallicity dispersions. Moreover, in the inner region of the SMC, clusters appear to be concentrated in two groups: one more metal-poor and another more metal-rich than field stars. Individually considered, neither cluster group presents an MG. Most surprisingly, the MG for both stellar populations (clusters and field stars) appears to reverse sign in the outer regions of the SMC. The difference between the cluster metallicity and the mean metallicity of the surrounding field stars turns out to be a strong function of the cluster metallicity. These results could be indicating different chemical evolution histories for these two SMC stellar populations. They could also indicate variations in the chemical behavior of the SMC in its internal and external regions.

    2016-10-01

    Maternal depression poses a risk for the developing mother-infant relationship. Similarly, maternal insecure attachment styles may limit the ability to adequately connect with the newborn during the postpartum period. The aim of this study was to investigate the effect of maternal depression and insecure attachment (insecure and dual/disorganized) on maternal bonding in a sample of n = 34 women with depression according to DSM-IV and n = 59 healthy women. Maternal depression was assessed 3 to 4 months postpartum with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), bonding with the Postpartum Bonding Questionnaire, and maternal attachment style with the Attachment Style Interview. Women with current and lifetime depression as well as women with dual/disorganized attachment style reported lower bonding. Explorative analysis revealed that depression partially mediated the link between dual/disorganized attachment style and bonding with a medium-sized mediation effect. The combination of maternal depression and dual/disorganized attachment style may pose a special risk constellation for the developing mother-infant bond that should be addressed in prevention and early intervention programs.

  18. Synthesis and characterization of a new inorganic cation-exchanger-Zr(IV) tungstomolybdate: Analytical applications for metal content determination in real sample and synthetic mixture

    International Nuclear Information System (INIS)

    An amorphous sample of inorganic cation-exchanger Zr(IV) tungstomolybdate was prepared by mixing varying ratios of 0.1 M aqueous solution of sodium tungstate and 0.1 M aqueous solution of sodium molybdate into 0.1 M aqueous solution of zirconium oxychloride at pH 1. This cation-exchanger was found to have a good ion-exchange capacity (2.40 mequiv. g-1 for Na+), high thermal and chemical stability. A tentative structural formula was proposed on the basis of chemical composition, FTIR and thermogravimetric analysis. Distribution coefficients (K d) values of metal ions in various solvent systems were determined. Some important and analytically difficult quantitative binary separations viz. Ni(II)-Pb(II), Ni(II)-Zn(II), Ni(II)-Cd(II), Mg(II)-Al(III), etc. were achieved. The practical applicability of the cation-exchanger was demonstrated in the separation of Cu(II)-Zn(II) from a synthetic mixture as well as from real samples of pharmaceutical formulation and brass alloy

  19. Machiavellianism and Parental Attachment in Adolescence

    Full Text Available Machiavellianism is a well-studied topic in several branches of psychology. Still, it has received little attention from a developmental perspective. Previous retrospective studies linked Machiavellianism to poor parental care, but actual reports of adolescents who live in their family of origin have been ignored so far. Therefore, we investigated the relationship between Machiavellianism and parental attachment in adolescence and possible sex differences based on life history theory. An adolescent sample (N = 376; 17.27 ± .77 years of age completed the Mach-IV and the maternal and paternal versions of revised Inventory of Parent and Peer Attachment (IPPA-R. According to our results, significant sex differences emerged in the relationship between Machiavellianism and attachment to parents. For girls, maternal alienation proved to be the only significant predictor of Machiavellianism, whereas for boys, low intensity and quality of verbal communication with father predicted higher levels of Machiavellianism. Results are discussed from an evolutionary perspective of socialization and from the perspective of emotion regulation.

  20. Asteroids IV

    Michel, Patrick; DeMeo, Francesca E.; Bottke, William F.

    . Asteroids, like planets, are driven by a great variety of both dynamical and physical mechanisms. In fact, images sent back by space missions show a collection of small worlds whose characteristics seem designed to overthrow our preconceived notions. Given their wide range of sizes and surface compositions, it is clear that many formed in very different places and at different times within the solar nebula. These characteristics make them an exciting challenge for researchers who crave complex problems. The return of samples from these bodies may ultimately be needed to provide us with solutions. In the book Asteroids IV, the editors and authors have taken major strides in the long journey toward a much deeper understanding of our fascinating planetary ancestors. This book reviews major advances in 43 chapters that have been written and reviewed by a team of more than 200 international authorities in asteroids. It is aimed to be as comprehensive as possible while also remaining accessible to students and researchers who are interested in learning about these small but nonetheless important worlds. We hope this volume will serve as a leading reference on the topic of asteroids for the decade to come. We are deeply indebted to the many authors and referees for their tremendous efforts in helping us create Asteroids IV. We also thank the members of the Asteroids IV scientific organizing committee for helping us shape the structure and content of the book.

    In this paper, the authors investigate the theoretical and empirical association between dysfunctions of the attachment system and borderline personality disorder. Attachment theory focuses on the maintenance of a sense of safety and security through a close personal relationship with a particular person. Based on a biological behavioural system, functional attachment relationships in adulthood rely on experiences and expectations of security within the relationship. These issues are also important to the definition and dynamics of borderline personality disorder. The dimensions and patterns of reciprocal attachment were compared with other scales measuring components of psychopathology and interpersonal relationships. In a sample of 85 female outpatients, only four of the attachment scales--feared loss, secure base, compulsive care-seeking and angry withdrawal--identified patients with high scores on a measure of borderline disorder. Of these four scales, feared loss had the predominant effect. These empirical results support the hypothesized relationship between dysfunctions of the attachment system and borderline disorder.

  2. On-line separation/preconcentration of V(IV)/V(V) in environmental water samples with CTAB-modified alkyl silica microcolumn and their determination by inductively coupled plasma-optical emission spectrometry

    International Nuclear Information System (INIS)

    A simple and selective method of flow injection microcolumn separation/preconcentration on-line coupled with inductively coupled plasma-optical emission spectrometry (ICP-OES) was developed for the speciation of V(V)/(IV). Various factors affecting the separation/preconcentration of V(IV) and V(V) by conical microcolumn packed with cetyltrimethylammonium bromide (CTAB)-modified alkyl silica have been systematically investigated. It is found that V(V) was quantitatively retained by the microcolumn at pH 2.0-7.0, while V(IV) was not retained by the microcolumn at pH 2.0-3.5 but quantitatively retained at pH 5.0-7.0. The two vanadium species adsorbed by the modified adsorbent were quantitatively desorbed by 0.10 mL of 1.0 mol L-1 HNO3. Therefore, V(V) and total vanadium could be determined by CTAB-modified alkyl silica packed microcolumn separation/preconcentration and on-line ICP-OES detection after adjusting sample solution to pH 2.5 and 6.0, respectively, and the assay of V(IV) was realized by subtracting V(V) from total V. The detection of limit (LOD) for V(V) was 0.03 μg L-1 with an enrichment factor of 27.9 for a 3.0 mL sample consumption. The relative standard deviations (RSDs) (CV(V) = CV(IV) = 5.0 μg L-1, n = 9) were 4.3% and 4.0% for V(V) and total V, respectively. The developed method was validated by the determination of V(IV) and V(V) in environmental water samples.

    We examined the prevalence and correlates of satisfaction with appearance and weight. Participants (N=12,176) completed an online survey posted on the NBCNews.com and Today.com websites. Few men and women were very to extremely dissatisfied with their physical appearances (6%; 9%), but feeling very to extremely dissatisfied with weight was more common (15%; 20%). Only about one-fourth of men and women felt very to extremely satisfied with their appearances (28%; 26%) and weights (24%; 20%). Men and women with higher body masses reported higher appearance and weight dissatisfaction. Dissatisfied people had higher Neuroticism, more preoccupied and fearful attachment styles, and spent more hours watching television. In contrast, satisfied people had higher Openness, Conscientious, and Extraversion, were more secure in attachment style, and had higher self-esteem and life satisfaction. These findings highlight the high prevalence of body dissatisfaction and the factors linked to dissatisfaction among U.S. adults. PMID:27172812

    Full Text Available A simple and selective method was developed for the determination of platinum(IV with n-octylaniline in toluene. In present study, the use of n-octylaniline in toluene for the extraction of platinum(IV from ascorbate media was carried out. The effect of various parameters, such as pH, equilibrium time, extractant concentration, and organic solvent on the extraction has been discussed. The back extraction of platinum(IV has been performed. On the basis of slope analysis, the composition of the extracted species was determined as [RR′NH2+ Pt(Succinate2−](org. The interfering effects of various cations and anions were also studied, and the selectivity of the method is enhanced by using suitable masking agents. The proposed method is rapid, reproducible and successfully applied for the determination of platinum(IV in binary and synthetic mixtures. The separation of pt(IV from other associated metals has been studied. Comparison of the results with those obtained using an atomic absorption spectrophotometer also tested the validity of the method.

    We employ a blindly selected sample of low-redshift C IV absorption systems identified in spectra from the Hubble Space Telescope (HST) Cosmic Origins Spectrograph (COS), combined with galaxy data from the Sloan Digital Sky Survey (SDSS), to study the metal-enriched circumgalactic medium (CGM) with ~100% completeness for galaxy luminosities L > 0.01 L* at z ~0.1 L* galaxies (7/8) than for less luminous galaxies (1/10). We also find that the occurrence of C IV absorbers depends strongly on the broader environment: 67% (8/12) of galaxies with rho < 150 kpc in regions of low galaxy density (regions with fewer than ten 0.1 L* galaxies within 1 Mpc) have affiliated C IV absorption while none (0/9) of the galaxies in denser regions show C IV within rho < 150 kpc. The reduced detection rate of C IV in denser environments persists for massive group dark matter halos. In contrast, H I is pervasive in the CGM without regard to mass or environment, although some of these Ly-alpha absorbers could arise in unrelated...

    2014-07-01

    The developed method is based on cold-induced aggregation microextraction of Se(IV) using the 1-butyl-3-methylimidazolium hexafluorophosphate ionic liquid as an extractant followed by spectrophotometry determination. The extraction of Se(IV) was performed in the presence of dithizone as the complexing agent. In this method, a very small amount of 1-butyl-3-methylimidazolium hexafluorophosphate was added to the sample solution containing Se-dithizone complex. Then, the solution was kept in a thermostated bath at 50 °C for 4 min. Subsequently, the solution was cooled in an ice bath and a cloudy solution was formed. After centrifuging, the extractant phase was analyzed using a spectrophotometric detection method. Some important parameters that might affect the extraction efficiency were optimized (HCl, 0.6 mol L(-1); dithizone, 4.0 × 10(-6) mol L(-1); ionic liquid, 100 μL). Under the optimum conditions, good linear relationship, sensitivity, and reproducibility were obtained. The limit of detection (LOD) (3Sb/m) was 1.5 μg L(-1), and the relative standard deviation (RSD) was 1.2 % for 30 μg L(-1) of Se(IV). The linear range was obtained in the range of 5-60 μg L(-1). It was satisfactory to analyze rice and various water samples. PMID:24590231

    This study determined the impact of impairment criteria on the prevalence and patterns of comorbidity of child DSM-IV disorders. The validity of these impairment criteria was tested against different measures of mental health care referral and utilization. We interviewed parents of 1,154 children aged 5-8 years in-depth using the Diagnostic Interview Schedule for Children in Rotterdam, the Netherlands, to establish DSM-IV diagnosis. These children were randomly selected or oversampled based on Child Behavior Checklist ratings from a large population-based study (N = 6,172). Referral data were extracted from the psychiatric interview as well as from a follow-up questionnaire. The results showed an overall prevalence of DSM-IV disorders of 31.1 % when impairment was not considered. This rate declined to 22.9 % when mild impairment was required and declined even further, to 10.3 %, for more severe levels of impairment. Similarly, the overall comorbidity rate declined from 8.5 to 6.7 and 2.7 % when mild and severe impairment were required, respectively. Virtually all children who attained symptom thresholds for a specific disorder, and had been referred to a mental health care professional because of the associated symptoms, also had mild impairment. The requirement of severe impairment criteria significantly increased diagnostic thresholds, but for most disorders, this definition captured only half of the clinically referred cases. In conclusion, prevalence was highly dependent upon the criteria used to define impairment. If severe impairment is made a diagnostic requirement, many children with psychiatric symptoms and mild impairment seeking mental health care will be undiagnosed and possibly untreated.

  10. BEHSA grafted polymer for selective extraction of U(VI), Th(IV) and La(III) from acidic matrices and also from environmental samples- a green process

    International Nuclear Information System (INIS)

    A new class of polymeric resin was synthesized by grafting Merrifield polymer with N,N-Bis-(2-ethyl-hexyl)-succinamic acid (BEHSA). The chemical modifications of the polymeric matrix were confirmed by FT-IR spectroscopy, CHNPS elemental analysis and also by thermo gravimetric analysis. Various physio-chemical parameters influencing the quantitative metal ion extraction by the resin phase were optimized by both static and dynamic methods. The significant feature of this grafted polymer is its ability to extract U(VI) and Th(IV) from highly acidic and near neutral matrices. (author)

    2006-04-01

    Grafted copolymers of poly(acrylic acid) (PAA) and poly(vinyl alcohol) (PVA) were prepared using a Ce(IV) glucose redox initiator by free radical polymerization. Three grafted copolymers having 20%, 50% and 80% grafting were selected for this study. Thus-modified polymer was characterized by means of Fourier transform infrared spectra, 1H NMR, gel permeation chromatography, thermogravimetric analysis and universal testing machine approaches. The membranes were prepared by a solution casting method, where the cross-linking process was performed through the in situ addition of glutaraldehyde and hydrochloric acid as the cross-linking agent and catalyst respectively. The following four membranes were prepared: (i) pure PVA; (ii) 20% grafted PVA; (iii) 50% grafted PVA; (iv) 80% grafted PVA. The membranes obtained were employed in the electroactive behavior study under a DC electric stimulus in different concentrations of electrolyte. The equilibrium bending angles (EBA) of these polymers were studied with respect to time, poly(acrylic acid) content, electric voltage applied across the polymer and ionic strength of the electrolyte used. Experimental results show stable reversibility of the bending behavior of these polymers under an applied DC electric field. The EBA increased with increase in the applied electric voltage and poly(acrylic acid) content within the polymer.

    Full Text Available Theory of attachment primarily described early relationships between a child and his caretakers. In the last twenty years there is a growing interest in adult attachment research. Theories and research findings of adult attachment stem from two different methodological approaches. The first approach measures adult attachment through Adult Attachment Interview (AAI; Main, 1991 where the attachment is assessed through the narratives of adult people of their early child experiences with their primary caretakers. The second approach measures adult attachment with the help of self-evaluative questionnaires, developed by (a Hazan and Shaver (1987 who started this approach in the field of personality and social psychology, and (b Bartholomew and Horowitz (1991. Research shows that there is significant correlation between early and adult attachment style. Attachment styles are passed from generation to generation. Basic adult attachment styles are: securely attached, preoccupied, fearful-avoidant, dismissing-avoidant and disorganized. Previous research using Barholomew and Horowitz (1991 Relationship Questionnaire on 176 Slovenian students showed that 48% students are securely attached, 29% are fearful-avoidant, 10% are dismissing-avoidant, and 13% have preoccupied attachment style. Theory of attachment is very useful for understanding the behavior and subjective experiences of children and adults. It is applicable to different contexts (psychotherapy, counseling, education .... The paper proposes further research focused on integration of adult attachment styles and types of object relations measured by Test of object relations (Žvelc, 1998 and Pictorial test of Separation and Individuation (Žvelc, 2003.

    Full Text Available Up to the present, the relationship between Machiavellianism and adult attachment has remained a question to be answered in the psychological literature. That is why this study focused on the relationship between Machiavellianism and attachment towards significant others in general interpersonal relationships and in intimate-close relationships. Two attachment tests (Relationship Questionnaire and long-form of Experiences in Close Relationship and the Mach-IV test were conducted on a sample consisting of 185 subjects. Results have revealed that Machiavellian subjects show a dismissing-avoidant attachment style in their general interpersonal relationships, while avoidance is further accompanied by some characteristics of attachment anxiety in their intimate-close relationships. Our findings further refine the relationship between Machiavellianism and dismissing-avoidant attachment. Machiavellian individuals not only have a negative representation of significant others, but they also tend to seek symbiotic closeness in order to exploit their partners. This ambitendency in distance regulation might be particularly important in understanding the vulnerability of Machiavellian individuals.

Laser-excited PTCDA-doped large argon, neon, and para-hydrogen clusters along with PTCDA embedded in helium nanodroplets are spectroscopically characterized with respect to line broadening and shifting. A fast non-radiative relaxation is observed before a radiative decay in the electronic ground state takes place.

  7. Attachment and Psychopathology

    Directory of Open Access Journals (Sweden)

    Mehmet Fatih Ustundag

    2011-06-01

    Full Text Available The type of attachment defined in the early stages of life and thought to be continuous, is a phenomenon that shapes the pattern of how a person makes contact with others. The clinical appearance of every type of attachment is different and each one has prospective and retrospective phenomenological reflections. In all stages of life and in close relationships, it can be observed if a person gets in close contact with someone else and if this relation bears supportive and protective qualities. According to attachment theorists, once it is defined as safe or unsafe during nursing period, it shows little change. Starting from Bowlby’s work, unsafe attachment type is considered as the determining factor of psychopathology in the later periods of life, while safe attachment is considered as in relation with healthy processes. The nature’s original model is safe attachment. Anxious/indecisive attachment, an unsafe attachment type, is associated with anxiety disorders and depressive disorder, while avoidant attachment is associated with behavior disorder and other extroverted pathologies. Disorganized/disoriented attachment is considered to be together with dissociative disorder. The aim of this paper is to review attachment theory and the relation between attachment and psychopathology.

    Full Text Available Research of attachment is numerous and versatile. They differ according to problems addressed, methodology applied (longitudinal studies, studies with horizontal designs, different instruments used, different methods of data analysis, and characteristics of samples involved (concerning age socio/economic status, family ecology. The research is commonly relied on the core assumptions of the theory itself, and the shared characteristic is orientation to explore complex phenomena of human experience and functioning. From the vast variety of research only those who most directly test the basic assumptions of the attachment theory are focused and addressed in the paper: representation of patterns of attachment in the childhood and adulthood, stability and change of attachment security from infancy to early adulthood, transgenerational transmission of attachment characteristics, the place and the role of attachment behavioral system in the personality development. The aim of the paper is to highlight the basic research and theory issues and directions, and illustrate them with concrete research date.

    2006-04-01

    The validity of Cloninger's psychobiological model and the Five-Factor Model of personality to predict DSM-IV personality disorders was examined in a psychiatric in-patient sample of 130 individuals. Patients completed Dutch authorized versions of the TCI (Cloninger, Svrakic, & Przybeck, 1993) and the NEO PI-R (Costa & McCrae, 1992) and were also administered the ADP-IV (Schotte & De Doncker, 1994), a Dutch self-report questionnaire to assess Axis-II disorders. No personality-descriptive model proved to be superior in explaining personality disorder symptoms at the higher-order level: the TCI dimensions better explained the Obsessive-Compulsive and the Narcissistic disorders, whereas the FFM accounted for more variance of the Avoidant disorder. However, differences were apparent at the lower-order level with the NEO facets out performing the TCI subscales for six to four personality disorders. FFM facet-level predictions of Widiger, Trull, Clarkin, Sanderson, and Costa (2002) were partially confirmed, with substantially better results using residualized facet scores. A set of TCI subscale personality disorder relationships is suggested. PMID:16529584

    Objectives The aim of the present study was to evaluate the association between socioeconomic status (SES) and psychiatric problems and violent behaviours in a nationally representative sample of Iranian children and adolescents, based on nationwide surveillance programme data, 2011–2012. Methods Overall, 14 880 students, aged 6–18 years, were selected using a multistage cluster sampling method from rural and urban areas of 30 provinces in Iran. SES was estimated based on a main summarised component, extracted from principle component analysis of family assets and parents' jobs and education. For statistical analysis, SES was classified as ‘low’, ‘middle’ and ‘high’. The WHO-Global School Based Student Health Survey (WHO-GSHS) questionnaire was used to assess psychiatric problems and violent behaviours. Results In total, 13 486 students (participation rate 90.6%) completed the study: 50.8% were boys and 75.6% were urban residents, with a mean age of 12.47±3.36 years. In the multivariate model, the ORs of depression, anxiety, feeling worthless, anger, insomnia, confusion and physical fights were lower in students with high SES compared with those with low SES (pbullying and being victimised. Conclusions Children and adolescents with low SES were at higher risk for psychiatric problems and violent behaviours. Mental health policies and public interventional strategies should be considered at the public level, notably for low SES families. PMID:27531729

    Context. Detecting and characterizing circumstellar dust is a way to study the architecture and evolution of planetary systems. Cold dust in debris disks only traces the outer regions. Warm and hot exozodiacal dust needs to be studied in order to trace regions close to the habitable zone. Aims. We aim to determine the prevalence and to constrain the properties of hot exozodiacal dust around nearby main-sequence stars. Methods. We search a magnitude limited (H < 5) sample of 92 stars for bright exozodiacal dust using our VLTI visitor instrument PIONIER in the H-band. We derive statistics of the detection rate with respect to parameters such as the stellar spectral type and age or the presence of a debris disk in the outer regions of the systems. We derive more robust statistics by combining our sample with the results from our CHARA/FLUOR survey in the K-band. In addition, our spectrally dispersed data allows us to put constraints on the emission mechanism and the dust properties in the detected systems. Re...

    We characterise the physical nature of a 1.1 mm-selected, flux-limited, and interferometrically followed up sample of SMGs in COSMOS. We used the MAGPHYS code to fit the multiwavelength (UV-radio) SEDs of 16 of the target SMGs. We also constructed the pure radio SEDs of our SMGs using three different radio bands (325 MHz, 1.4 GHz, and 3 GHz). Moreover, since two SMGs in our sample, AzTEC1 and AzTEC3, benefit from previous CO line observations, we studied their properties in more detail. We found that 63% of our target SMGs lie above the galaxy main-sequence by more than a factor of 3, and hence are starbursts. The 3 GHz radio sizes we have previously measured for the target SMGs were compared with the present stellar mass estimates, and we found that the z>3 SMGs are fairly consistent with the mass-size relationship of z~2 compact, quiescent galaxies (cQGs). The median IR-radio correlation parameter is found to be q=2.27, which is lower than measured locally (median q=2.64). AzTEC1 is found to have a sub-Eddi...

    Background The consumption of tobacco through a hookah is growing in popularity, especially among children and adolescents, but little is known about the determinants of hookah smoking. Objectives The current study aimed to assess the determinants of tobacco smoking and hookah smoking in a nationally representative sample of Iranian children and adolescents. Patients and Methods This study was conducted as part of the fourth cross-sectional survey of a national school-based program. Using a cluster random sampling method, a validated questionnaire was completed anonymously by 14,880 students who were aged 6 - 18 years and living in urban and rural areas of 30 provinces in Iran. Results The final study group consisted of 13,486 children and adolescents (participation rate of 90.6%), of whom 49.2% were girls and 75.6% were urban residents. The mean age was 12.47 ± 3.36 years. According to the self-reports of the students, 2.6% (3.5% of boys and 1.7% of girls) were current tobacco smokers, 5.9% (7.5% of boys and 4.2% of girls) were ever tobacco smokers, and 1.8% (2.49% of boys and 1.14% of girls) were current hookah smokers. Based on a multiple logistic regression (MLR) model, the following factors increased the risk of current smoking: age, number of days spent with friends per week, hookah smoking or cigarette smoking by the father, hookah smoking by siblings, hookah smoking by other members of the family, and screen time. The age, number of days spent with friends, hookah or cigarette smoking by the father, hookah smoking by siblings, and screen time increased the risk of hookah smoking. Female gender and living in rural areas decreased the risk of current tobacco and hookah smoking. Conclusions Preventive measures against tobacco use should be underscored for Iranian families. The preparation of strategies on the promotion of a healthy lifestyle should be considered a health priority.

    We have carried out a high-precision astrometric analysis of two very-long-baseline-interferometry (VLBI) epochs of observation of the 13 extragalactic radio sources in the complete S5 polar cap sample. The VLBI epochs span a time baseline of 10 years and enable us to achieve precisions in the proper motions of the source cores up to a few micro-arcseconds per year. The observations were performed at 14.4 GHz and 43.1 GHz, and enable us to estimate the frequency core-shifts in a subset of sources, for which the spectral-index distributions can be computed. We study the source-position stability by analysing the changes in the relative positions of fiducial source points (the jet cores) over a decade. We find motions of 0.1-0.9 mas among close-by sources between the two epochs, which imply drifts in the jet cores of approximately a few tens of micro-as per year. These results have implications for the standard Active Galactic Nucleus (AGN) jet model (where the core locations are supposed to be stable in time)....

    The Personality Psychopathology Five (PSY-5) model represents 5 broadband dimensional personality domains that align with the originally proposed DSM-5 personality trait system, which was eventually placed in Section III for further study. The main objective of this study was to examine the associations between the PSY-5 model and personality disorder criteria. More specifically, we aimed to determine if the PSY-5 domain scales converged with the alternative DSM-5 Section III model for personality disorders, with a particular emphasis on the personality trait profiles proposed for each of the specific personality disorder types. Two samples from The Netherlands consisting of clinical patients from a personality disorder treatment program (n = 190) and forensic psychiatric hospital (n = 162) were used. All patients had been administered the MMPI-2 (from which MMPI-2-RF PSY-5 scales were scored) and structured clinical interviews to assess personality disorder criteria. Results based on Poisson or negative binomial regression models showed statistically significant and meaningful associations for the hypothesized PSY-5 domains for each of the 6 personality disorders, with a few minor exceptions that are discussed in detail. Implications for these findings are also discussed.

    We present a pilot study of ~3'' resolution observations of low CO transitions with the Submillimeter Array in three nearby Seyfert galaxies, which are part of the low-luminosity quasi-stellar object (LLQSOs) sample consisting of 99 nearby (z = 0.06) type-1 active galactic nuclei (AGN) taken from the Hamburg/ESO quasi-stellar object (QSO) survey. Two sources were observed in 12CO(2-1) and 13CO(2-1) and the third in 12CO(3-2) and HCO+(4-3). None of the sources is detected in continuum emission. More than 80% of the 12CO detected molecular gas is concentrated within a diameter (FWHM) 1.5 × 109M⊙ and for the dust masses of Mdust> 1.6 × 106M⊙. The R21 = 12CO/13CO(2-1) line luminosity ratios show Galactic values of R21 ~ 5-7 in the outskirts and R21 ≳ 20 in the central region, similar to starbursts and (ultra)luminous infrared galaxies ((U)LIRGs; i.e. LIRGs and ULIRGs), implying higher temperatures and stronger turbulence. All three sources show indications of 12CO(2-1)/12CO(1-0) ratios of ~0.5, suggesting a cold or diffuse gas phase. Strikingly, the 12CO(3-2)/(1-0) ratio of ~1 also indicates a higher excited phase. Since these galaxies have high infrared luminosities of LIR ≥ 1011L⊙ and seem to contain a circumnuclear starburst with minimum surface densities of gas and star formation rate (SFR) around Σmol = 50-550 M⊙pc-2 and ΣSFR = 1.1-3.1 M⊙ kpc-2 yr-1, we conclude that the interstellar medium in the centers of these LIRG Seyferts is strongly affected by violent star formation and better described by the ULIRG mass conversion factor.

    Full Text Available Background: The aim of this study was to evaluate the association of Socioeconomic Status (SES with anthropometric measures and BP in Iranian children and adolescents.Methods: This nationwide study was conducted in 2011-2012 among 14,880 students, aged 6-18 years, selected by multistage, cluster-sampling method from rural and urban areas of 30 provinces of Iran. Anthropometric indexes and BP were measured by standard protocols and with calibrated instruments. SES was estimated based on family assets and parents’ job and education using principle component analysis method. SES was considered as “low”, “intermediate” and “high” in the statistical analysis.Results: Overall, 13486 children and adolescents out of 14,880 invited students (response rate 90.6% participated in this study. They consisted of 50.8% boys, 75.6% urban residents, with a mean age of 12.47 ±3.36 years. The prevalence of overweight, obesity and abdominal obesity and also mean of all anthropometric measures increased linearly with increasing SES. Inversely, underweight decreased linearly with increasing SES. Association of BP measures with SES was not statistically significant. After adjustment for potential confounders, association of anthropometric measures and BP with SES did not change significantly.Conclusion: We found that obesity, overweight and abdominal obesity was prevalent in high SES group and underweight in low SES group. Our findings serve as confirmatory evidence that contrary to developed countries, in developing countries childhood obesity is more prevalent in families with higher SES. Keywords: Anthropometric measures, Blood pressure, Socio-economic status, Children and adolescents, Iran

    1996-04-01

    The relationships among attachment classification, psychopathology, and personality traits were examined in a group of 60 psychiatrically hospitalized adolescents. The concordance of attachment classification was examined in 27 adolescent-mother pairs. Both adolescent and maternal attachment status were overwhelmingly insecure and were highly concordant. Adolescents showing a dismissing attachment organization were more likely to have a conduct or substance abuse disorder, narcissistic or antisocial personality disorder, and self-reported narcissistic, antisocial, and paranoid personality traits. Adolescents showing a preoccupied attachment organization were more likely to have an affective disorder, obsessive-compulsive, histrionic, borderline or schizotypal personality disorder, and self-reported avoidant, anxious, and dysthymic personality traits. The results support a model of development of psychopathology based partially on relational experiences with parents.

    This study examined the intergenerational continuities and changes in infant attachment patterns within a higher-risk longitudinal sample of 55 female participants born into poverty. Infant attachment was assessed using the Strange Situation when participants were 12 and 18 months as well as several decades later with participants' children. Paralleling earlier findings from this sample on the stability of attachment patterns from infancy to young adulthood, results provided evidence for intergenerational continuities in attachment disorganization but not security. Children of adults with histories of infant attachment disorganization were at an increased risk of forming disorganized attachments. Although changes in infant attachment patterns across the two generations were not correlated with individuals' caregiving experiences or interpersonal stresses and supports during childhood and adolescence, higher quality social support during adulthood was associated with intergenerational changes from insecure to secure infant-caregiver attachment relationships.

    Because there has been relatively little communication and cross-fertilization between the two major lines of research on adult attachment, one based on coded narrative assessments of defensive processes, the other on simple self-reports of 'attachment style' in close relationships, we here explain and review recent work based on a combination of self-report and other kinds of method, including behavioral observations and unconscious priming techniques. The review indicates that considerable progress has been made in testing central hypotheses derived from attachment theory and in exploring unconscious, psychodynamic processes related to affect-regulation and attachment-system activation. The combination of self-report assessment of attachment style and experimental manipulation of other theoretically pertinent variables allows researchers to test causal hypotheses. We present a model of normative and individual-difference processes related to attachment and identify areas in which further research is needed and likely to be successful. One long-range goal is to create a more complete theory of personality built on attachment theory and other object relations theories.

    It is difficult to think of any behavioural process that is more intrinsically important to us than attachment. Feeding, sleeping and locomotion are all necessary for survival, but humans are, as Baruch Spinoza famously noted, "a social animal" and it is our social attachments that we live for. Over the past decade, studies in a range of vertebrates, including humans, have begun to address the neural basis of attachment at a molecular, cellular and systems level. This review describes some of the important insights from this work.

    2012-03-01

    Full Text Available The main goal of this study was localization of attachment dimensions in the space described by basic personality traits. Study purported to examine relations between attachment and basic personality structure, in a sample of 203 respondents. Romantic adult attachment was measured by the Experience in Close Relationship Scale, basic personality structure was assessed by the NEO-PI-R personality inventory, and Disintegration, which represents operationalization of Schizotypy as a basic personality trait, was estimated by the Delta 10 test. The results of Principal component analysis showed that attachment dimensions are not separate constructs in relation to basic personality traits. Furthermore, results indicate that attachment dimensions represent emotional dysregulation in close interpersonal relationships, because positive correlations are found between dimensions of Attachment and Mania (.35, Anxiety (.51 and Depression (.55. Negative correlations have been obtained between Attachment and Positive emotions (-.34 and Feelings (-.31. These results suggest that Attachment dimensions should be considered as an expression of basic personality traits in romantic adult's relationships.

    The Wechsler Adult Intelligence Scale-fourth edition (WAIS-IV) and the Wechsler Memory Scale-fourth edition (WMS-IV) were co-developed to be used individually or as a combined battery of tests. The independent factor structure of each of the tests has been identified; however, the combined factor structure has yet to be determined. Confirmatory factor analysis was applied to the WAIS-IV/WMS-IV Adult battery (i.e., age 16-69 years) co-norming sample (n = 900) to test 13 measurement models. The results indicated that two models fit the data equally well. One model is a seven-factor solution without a hierarchical general ability factor: Verbal Comprehension, Perceptual Reasoning, Processing Speed, Auditory Working Memory, Visual Working Memory, Auditory Memory, and Visual Memory. The second model is a five-factor model composed of Verbal Comprehension, Perceptual Reasoning, Processing Speed, Working Memory, and Memory with a hierarchical general ability factor. Interpretative implications for each model are discussed.

    2000-01-01

    This study examined the relationships between childhood attachment and coercive sexual behavior. One hundred sixty-two male undergraduate students completed self-report measures of childhood maternal attachment, childhood paternal attachment, adult attachment, antisociality, aggression, and coercive sexual behavior. As predicted, insecure childhood attachment, especially insecure paternal attachment, was associated with antisociality, aggression, and coercive sexual behavior. Moreover, childhood attachment independently predicted coercive sexual behavior after antisociality and aggression were statistically controlled. The hypothesis that paternal avoidant attachment would predict coercive sexual behavior independently of its relationship with aggression and antisociality was also supported. Posthoc analysis indicated that maternal anxious attachment was associated with antisociality and that paternal avoidant attachment was associated with both antisociality and coercive sexual behavior. These results are consistent with criminological and psychological research linking adverse early family experiences with offending and lend support to an attachment-theoretical framework for understanding offending behavior in general and sexual offending behavior in particular.

    Theoretical models of social anxiety propose that attention biases maintain symptoms of social anxiety. Research findings regarding the time course of attention and social anxiety disorder have been mixed. Adult attachment style may influence attention bias and social anxiety, thus contributing to the mixed findings. This study investigated the time course of attention toward both negative and positive stimuli for individuals diagnosed with social anxiety disorder (SAD) and assessed whether attachment style moderates this relationship. One hundred and thirty participants (age: M=29.03) were assessed using a semistructured clinical interview. Those meeting eligibility criteria for the clinical sample met DSM-IV criteria for SAD (n=90, age: M=32.18), while those in the control sample did not meet criteria for any mental disorder (n=23, age: M=26.04, 11 females). All participants completed self-report measures examining depression, social anxiety, adult attachment style, and completed an eye-tracking task used to measure the time course of attention. Eye-tracking data were analysed using growth curve analysis. The results indicate that participants in the control group overall displayed greater vigilance towards emotional stimuli, were faster at initially fixating on the emotional stimulus, and had a greater percentage of fixations towards the emotional stimulus as the stimulus presentation time progressed compared to those in the clinical group. Thus, the clinical participants were more likely to avoid fixating on emotional stimuli in general (both negative and positive) compared to those in the control group. These results support the Clark and Wells (1995) proposal that socially anxious individuals avoid attending to emotional information. Attachment style did not moderate this association, however anxious attachment was related to greater vigilance toward emotional compared to neutral stimuli. PMID:27423171

    Attention underlies and energizes all cognitive and behavioral activities. Many studies showed that the quality of child attachment (both to parental and non parental figures) influences cognitive functions and attention. This study aimed to investigate the relationships among attachment to preschool teachers and attention in a sample of preschoolers. In particular, the study analyzed whether child attachment security to preschool teachers influences the different aspects of their attention skills. In addition, gender- and age-related differences in attention and teacher attachment were explored. Research was conducted using two standardized instruments: the Attention and Concentration Battery, and the Attachment Q Sort. Participants were 279 children (147 male, 132 female) who attended two preschools in a town in Southern Italy. Descriptive analyses, t-tests analyses, and correlation and regression analyses were carried out. Findings highlighted several interesting points concerning the relationships that occur among attachment to preschool teachers and attention. Children with secure attachments presented higher reaction time and better auditory, visual, and visual spatial selectivity and maintenance.

    Full Text Available Growing evidence shows that attachment is a key risk factor for the diagnosis and treatment of clinical diseases in Axis I, such as drug addiction. Recent literature regarding attachment, psychiatric pathology and drug addiction demonstrates that there is a clear prevalence of insecure attachment patterns in clinical and drug addicted subjects. Specifically, some authors emphasize that the anxious-insecure attachment pattern is prevalent among drug-addicted women with double diagnosis (Fonagy et al., 1996. The construct of attachment as a risk factor in clinical samples of drug-addicted mothers needs to be studied more in depth though. The present explorative study focused on the evaluation of parenting quality in a therapeutic mother-child community using attachment and personality assessment tools able to outline drug-addicted mothers’ profiles. This study involved 30 drug addicted mothers, inpatients of a therapeutic community. Attachment representations were assessed via the Adult Attachment Interview; personality diagnosis and symptomatic profiles were performed using the Structured Clinical Interview of the DSM-IV (SCID-II and the Symptom Check List-90-R (SCL-90-R respectively. Both instruments were administered during the first six months of residence in a therapeutic community. Results confirmed the prevalence of insecure attachment representations (90%, with a high presence of U patterns, prevalently scored for dangerous and/or not protective experiences in infanthood. Very high values (>5 were found for some experience scales (i.e. neglect and rejection scales. Data also showed very low values (1-3 in metacognitive monitoring, coherence of transcript and coherence of mind scales. Patients’ different profiles (U vs. E vs. Ds were linked to SCID-II diagnosis, providing insightful indications both for treatment planning and intervention on parenting functions and for deciding if to start foster care or adoption proceedings for

    Full Text Available The present study aims to determine the attachment of adolescents to their parents according to geographical regions in Turkey and gender. The research group consisted of 6061 adolescents. With an age average of 15.53 years. The Inventory of Attachment to Parents and Friends- Brief Form (EABE was used as data acquisition tool. The results of the study indicated significant difference between the scores of students regarding the inventory of attachment to parents according to regions. Evaluating the findings regarding attachment to father and mother together, the findings were similar, and the attachment levels of adolescents in Middle Anatolia, Eastern Anatolia and Black Sea Region were found to be higher than the ones in other regions. This result may be related with socioeconomic, geographical and cultural structures of the regions. Examining the finding according to gender variable, the scores of male students are significantly lower than the scores of female students. As a result according to the data gained from a wide sample group; the main factors for the attachment of adolescents to their parents in Turkey are the geographical regions in Turkey and the gender.

    Full Text Available The capacity to be mindfully aware of the present moment without judgment is associated with a number of positive psychological and physiological outcomes. Experiences in attachment relationships are related to specific cognitive-emotional patterns that may contribute to dispositional mindfulness. A sample of adults (N = 93 completed questionnaires regarding adult attachment, rumination, thought suppression, attentional control, and mindfulness. Attachment-related avoidance predicted lower levels of mindfulness, a relation mediated by thought suppression and poorer attentional control. Attachment-related anxiety also predicted lower levels of mindfulness, a relation mediated by rumination and poorer attentional control. The results suggest that in the context of insecure attachment relationships thought suppression and rumination defend against personal and interpersonal losses by deactivating (in the case of avoidance or hyperactivating (in the case of anxiety the attachment system. These habitual defensive patterns may be important links between adult attachment orientations and mindfulness.

    International Nuclear Information System (INIS)

    The equilibrium solubility of neptunium (IV) oxalate in nitric/oxalic acid solutions was determined at 220C, 450C, and 600C. The concentrations of nitric/oxalic acid solutions represented a wide range of free oxalate ion concentration. A mathematical solubility model was developed which is based on the formation of the known complexes of neptunium (IV) oxalate. the solubility model uses a simplified concentration parameter which is proportional to the free oxalate ion concentration. The solubility model can be used to estimate the equilibrium solubility of neptunium (IV) oxalate over a wide range of oxalic and nitric acid concentrations at each temperature

    2011-12-01

    Full Text Available Abstract Background The three bacteriophage genes gtrA, gtrB and gtr(type are responsible for O-antigen glucosylation in Shigella flexneri. Both gtrA and gtrB have been demonstrated to be highly conserved and interchangeable among serotypes while gtr(type was found to be specific to each serotype, leading to the hypothesis that the Gtr(type proteins are responsible for attaching glucosyl groups to the O-antigen in a site- and serotype- specific manner. Based on the confirmed topologies of GtrI, GtrII and GtrV, such interaction and attachment of the glucosyl groups to the O-antigen has been postulated to occur in the periplasm. Results In this study, the topology of GtrIV was experimentally determined by creating different fusions between GtrIV and a dual-reporter protein, PhoA/LacZ. This study shows that GtrIV consists of 8 transmembrane helices, 2 large periplasmic loops, 2 small cytoplasmic N- and C- terminal ends and a re-entrant loop that occurs between transmembrane helices III and IV. Though this topology differs from that of GtrI, GtrII, GtrV and GtrX, it is very similar to that of GtrIc. Furthermore, both the N-terminal periplasmic and the C-terminal periplasmic loops are important for GtrIV function as shown via a series of loop deletion experiments and the creation of chimeric proteins between GtrIV and its closest structural homologue, GtrIc. Conclusion The current study provides the basis for elucidating the structure and mechanism of action of this important O-antigen modifying glucosyltransferase.

  10. Universally Rigid Framework Attachments

    A framework is a graph and a map from its vertices to R^d. A framework is called universally rigid if there is no other framework with the same graph and edge lengths in R^d' for any d'. A framework attachment is a framework constructed by joining two frameworks on a subset of vertices. We consider an attachment of two universally rigid frameworks that are in general position in R^d. We show that the number of vertices in the overlap between the two frameworks must be sufficiently large in order for the attachment to remain universally rigid. Furthermore, it is shown that universal rigidity of such frameworks is preserved even after removing certain edges. Given positive semidefinite stress matrices for each of the two initial frameworks, we analytically derive the PSD stress matrices for the combined and edge-reduced frameworks. One of the benefits of the results is that they provide a general method for generating new universally rigid frameworks.

    In this work we study the characteristics of moving type IV radio bursts which extend to the hectometric wavelengths (interplanetary type IV or type IV IP bursts) and their relationship with energetic phenomena on the Sun. Our dataset comprised 48 Interplanetary type IV bursts observed by the Wind/WAVES in the 13.825 MHz?20 KHz frequency range. The dynamic spec tra of the RSTN, DAM, ARTEMIS-IV, CULGOORA, Hiraiso and IZMIRAN Radio-spectrographs were used to track the evolution of the events in the low corona; these were supplemented with SXR ?ux recordings from GOES and CME data from LASCO. Positional information for the coronal bursts were obtained by the Nan\\c{c}ay radioheliograph (NRH). We examined the relationship of the type IV events with coronal radio bursts, CMEs and SXR ?ares. The majority of the events (45) were characterized as compact; their duration was on average 106 min. This type of events were, mostly, associated with M and X class ?ares (40 out of 45) and fast CMEs; 32 of these events had CME...

    2013-12-01

    Extant research has demonstrated that compared to adults with insecure attachment styles, more securely attached parents tend to be more responsive, sensitive, and involved parents, resulting in improved outcomes for their children. Less studied is the influence of a mother's attachment style on her attachment to her unborn child during pregnancy and the consequent developmental outcomes of the child during early childhood. Thus, the aim of this prospective longitudinal study was to examine the relationship between maternal-fetal attachment (MFA) during pregnancy and infant and toddler outcomes and the role of mothers' attachment style on early childhood developmental outcomes in an economically disadvantaged sample of women and their children. Gamma regression modeling demonstrated that an avoidant maternal attachment style (b = .98, 95 % CI [.97, .98], p styles and greater depressive symptomatology were more likely to have children demonstrating early childhood developmental delays than those women with less avoidant attachment styles and less depressive symptomatology. Furthermore, women reporting higher MFA during pregnancy had more secure attachment styles, and their children had more optimal early childhood development than those women reporting lower MFA and less secure attachment styles. Findings have implications for enhancing early intervention programs aimed at improving maternal and childhood outcomes. An earlier identification of disruptions in attachment may be beneficial in tailoring interventions focused on the mother-child dyad.

    2015-01-01

    The Adult Attachment Interview (AAI) and the Adult Attachment Projective (AAP) purport to measure the same attachment classifications. The aims of this study were to determine the concurrent validity of the AAI and AAP, and to compare their ability to predict indicators of risk associated with socioeconomic status (SES), depression, and 5-HTTLPR genotype. Results indicated no agreement between AAI and AAP attachment classifications in a sample of late adolescents. As predicted, individuals classified as "unresolved" with regard to loss or trauma were significantly more likely to be of lower SES, have higher levels of depression, and have the 5-HTTLPR "ss" genotype than individuals with secure, preoccupied, or dismissing attachments. These associations, however, were only significant when attachment was classified with the AAI. Results suggest that the AAI and AAP measure different facets of attachment as a result of their unique methodologies and coding criteria. Further research is needed to support their comparability before investigators can assume that the AAP is a valid substitute for the AAI. PMID:26362584

    2014-01-01

    Attachment researchers have proposed that the attachment, caregiving, and sexual behavioral systems are interrelated in adult love relationships (Mikulincer & Shaver, 2007 ). This study examined whether aspects of partners' caregiving (proximity, sensitivity, control, compulsive caregiving) mediated the association between their attachment insecurities (anxiety and avoidance) and each other's sexual satisfaction in two samples of committed couples (Study 1: 126 cohabiting or married couples from the general community; Study 2: 55 clinically distressed couples). Partners completed the Experiences in Close Relationships measure (Brennan, Clark, & Shaver, 1998 ), the Caregiving Questionnaire (Kunce & Shaver, 1994 ), and the Global Measure of Sexual Satisfaction (Lawrance & Byers, 1998 ). Path analyses based on the actor-partner interdependence model (APIM) revealed that caregiving proximity mediated the association between low attachment avoidance and partners' sexual satisfaction in distressed and nondistressed couples. Sensitivity mediated this association in nondistressed couples only. Control mediated the association between men's insecurities (attachment-related avoidance and anxiety) and their partners' low sexual satisfaction in nondistressed couples. Attachment anxiety predicted compulsive caregiving, but this caregiving dimension was not a significant mediator. These results are discussed in light of attachment theory and their implications for treating distressed couples.

    2007-01-01

    The present study examined self-reported romantic attachment style and Adult Attachment Interview (AAI) states of mind regarding early attachment relationships, personality dimensions, and psychopathology in a psychiatric sample of trauma survivors. Inpatients (N = 80) admitted to a hospital trauma treatment program were administered the Experiences in Close Relationships Scale, AAI, Millon Clinical Multiaxial Inventory-III, Dissociative Experiences Scale, and Dissociative Disorder Interview Schedule. Self-report and AAI attachment classifications were not related, and different results emerged for the two measures. Self-reported romantic attachment style was significantly associated with personality dimensions, with fearful adults showing the most maladaptive personality profiles. Findings suggested that self-report dimensions of self and other independently contribute to different forms of psychological dysfunction. AAI unresolved trauma was uniquely associated with dissociation and posttraumatic stress disorder, whereas unresolved trauma and unresolved loss jointly contributed to schizotypal and borderline personality disorder scores. The differences in findings between the two measures are discussed with a view toward the developmental and clinical implications. PMID:17241494

    Full Text Available Background: Based on Bowlby's attachment theory, Bartholomew proposed a four-category attachment typology by which individuals judged themselves and adult relationships. This explanatory model has since been used to help explain the risk of psychiatric comorbidity. Objective: The current study aimed to identify attachment typologies based on Bartholomew's attachment styles in a sample of bereaved parents on dimensions of closeness/dependency and anxiety. In addition, it sought to assess the relationship between the resultant attachment typology with a range of psychological trauma variables. Method: The current study was based on a sample of 445 bereaved parents who had experienced either peri- or post-natal death of an infant. Adult attachment was assessed using the Revised Adult Attachment Scale (RAAS while reaction to trauma was assessed using the Trauma Symptom Checklist (TSC. A latent profile analysis was conducted on scores from the RAAS closeness/dependency and anxiety subscales to ascertain if there were underlying homogeneous attachment classes. Emergent classes were used to determine if these were significantly different in terms of mean scores on TSC scales. Results: A four-class solution was considered the optimal based on fit statistics and interpretability of the results. Classes were labelled “Fearful,” “Preoccupied,” “Dismissing,” and “Secure.” Females were almost eight times more likely than males to be members of the fearful attachment class. This class evidenced the highest scores across all TSC scales while the secure class showed the lowest scores. Conclusions: The results are consistent with Bartholomew's four-category attachment styles with classes representing secure, fearful, preoccupied, and dismissing types. While the loss of an infant is a devastating experience for any parent, securely attached individuals showed the lowest levels of psychopathology compared to fearful, preoccupied, or dismissing

    We study the characteristics of moving type IV radio bursts that extend to hectometric wavelengths (interplanetary type IV or type {IV}_{{IP}} bursts) and their relationship with energetic phenomena on the Sun. Our dataset comprises 48 interplanetary type IV bursts observed with the Radio and Plasma Wave Investigation (WAVES) instrument onboard Wind in the 13.825 MHz - 20 kHz frequency range. The dynamic spectra of the Radio Solar Telescope Network (RSTN), the Nançay Decametric Array (DAM), the Appareil de Routine pour le Traitement et l' Enregistrement Magnetique de l' Information Spectral (ARTEMIS-IV), the Culgoora, Hiraso, and the Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation (IZMIRAN) Radio Spectrographs were used to track the evolution of the events in the low corona. These were supplemented with soft X-ray (SXR) flux-measurements from the Geostationary Operational Environmental Satellite (GOES) and coronal mass ejections (CME) data from the Large Angle and Spectroscopic Coronagraph (LASCO) onboard the Solar and Heliospheric Observatory (SOHO). Positional information of the coronal bursts was obtained by the Nançay Radioheliograph (NRH). We examined the relationship of the type IV events with coronal radio bursts, CMEs, and SXR flares. The majority of the events (45) were characterized as compact, their duration was on average 106 minutes. This type of events was, mostly, associated with M- and X-class flares (40 out of 45) and fast CMEs, 32 of these events had CMEs faster than 1000 km s^{-1}. Furthermore, in 43 compact events the CME was possibly subjected to reduced aerodynamic drag as it was propagating in the wake of a previous CME. A minority (three) of long-lived type {IV}_{{IP}} bursts was detected, with durations from 960 minutes to 115 hours. These events are referred to as extended or long duration and appear to replenish their energetic electron content, possibly from electrons escaping from the corresponding coronal

    2003-04-01

    Full Text Available On the basis of the study of recent scientific literature about the development of attachment, the author answers the following questions: which are the postulates the theory of attachment has about the stability of the patterns of attachment, which level of stability in the patterns of attachment from infancy to adulthood these studies illuminate and which factors significantly influence the (instability of the patterns of attachment in time. The theory of attachment assumes that normal circumstances elicit stability. Changes, however, can be the result of important events influencing the sensitivity of the object of attachment. Agreement has not yet been reached regarding the percentage of stability in the patterns of attachment. There is more agreement regarding attachment in adulthood than that in childhood. The results depend on the size and characteristics of the subjects of the research, the measuring instruments, type of data analysis etc. The author concludes that attachment is a dynamic system influenced by significant changes in life (the cognitive development of the child, external care, parents' divorce, different stressful situations. As the influence of stressful events on the individual person' s quality of attachment is examined, it is necessary to consider also his/her temperamental characteristics, role of other people in their lives, etc.

The spatial distribution of mapped landscape values or values home range is related to, but not identical to mapped place...... attachment with just over half of landscape values located outside the area of mapped place attachment. Economic livelihood values, as an indicator of place dependence, and social values, as an indicator of place identity, are more likely to be mapped within the place attachment area.

    four selfrepot questionnaires. The childhood attachment was measured by Attachment History Paragraphs (Granqvist & Kirkpatrick, 2004, adult attachment was measured by The Experiences in Close Relationships Questionnaire (Brennan, Clark, & Shaver, 1998 and satisfaction in marriage was measuredby two measures: Quality Marriage Index (Norton, 1983 and Kansas Marital Satisfaction Scale (Schumm, Bollman, & Jurich, 1997.The research sample consisted of 78 heterosexual married couple, together 156 people. The average length of marriages is 20.76 years. Participants were instructed to complete the questionnaires independently. The relations between variables were examined by correlation analysis and cluster analysis. People with a secure attachment style and their partners were most satisfied with their marriages. Our study showed relation between dismissive attachment style and low level of marital satisfaction for the individual, and for the partner of the examined one. The results of our study did not suggest any relationship between childhood attachment and marital satisfaction. The results indicate that secure attachment style is related to higher level of relationship satisfaction, in spite of stressful situation or demanding changes which are occurring in marriage. People with insecure attachment style devote a lot of effort to reinforce marital and couple relationship stability during difficult situations in relationship. Connection between marital satisfaction and childhood attachment has not been proven. The reason may be that childhood attachment is not always totally stable and it can be changed by life experience or personal characteristics of the individual. Our research confirmed that attachment is related to satisfaction in marriage. Research of relationship between attachment and factors affecting marriage is very beneficial, because new finding in this topic can help in clinical practice.

  19. Associations between adult attachment dimensions and attitudes toward pain behaviour

    McWilliams, Lachlan A; Murphy, Paul DJ; Bailey, S Jeffrey

    2010-01-01

    BACKGROUND: Despite the important role positive reinforcement of pain behaviour is believed to play in chronic pain, there is a paucity of research regarding factors that influence the provision of such reinforcement. Attachment theory suggests that individuals high in attachment avoidance view the pain behaviour of others in a negative manner and would, therefore, provide little reinforcement of pain behaviour. As an initial step in evaluating this model, relationships between attachment dimensions and attitudes toward pain behaviour were examined. Attachment avoidance was hypothesized to be negatively associated with accepting attitudes toward pain behaviour. METHODS: A sample of undergraduate students (n=160) completed the Relationships Structures Questionnaire, which provides global ratings of adult attachment dimensions (anxiety and avoidance) by assessing attachment across four relationship targets (friend, mother, father and romantic partner). Attitudes regarding the acceptability of pain behaviour were assessed using male and female versions of the Appropriate Pain Behaviour Questionnaire (APBQ). RESULTS: Consistent with the hypothesis, attachment avoidance was negatively correlated with both APBQ-Female and APBQ-Male scores. Multiple regression analyses were used to investigate the relationships between the attachment scales and the APBQ scales while statistically adjusting for sex and testing for interaction effects. The findings revealed complex relationships involving interaction effects that provided further support for the hypothesis. CONCLUSIONS: The findings provided support for the hypothesis that attachment avoidance is associated with less accepting attitudes toward pain behaviour. Additional research regarding the role of attachment and attitudes on responses to pain behaviour is warranted. PMID:21165372

  20. Parental divorce and adult children's attachment representations and marital status.

    2009-01-01

    The purpose of this study was to explore adult attachment as a means of understanding the intergenerational transmission of divorce, that is, the propensity for the children of divorce to end their own marriages. Participants included 157 couples assessed 3 months prior to their weddings and 6 years later. Participants completed the Adult Attachment Interview and questionnaires about their relationships, and were videotaped with their partners in a couple interaction task. Results indicated that, in this sample, adult children of divorce were not more likely to divorce within the first 6 years of marriage. However, parental divorce increased the likelihood of having an insecure adult attachment status. For women, age at the time of their parents' divorce was related to adult attachment status, and the influence on attachment representations may be more enduring. Among adult children of divorce, those who were classified as secure in their attachment representations were less likely to divorce in the early years of marriage than insecure participants.

    Although research has examined associations between attachment dimensions and relationship outcomes, theory has ignored how these associations change over time in adult romantic relationships. We proposed the Temporal Adult Romantic Attachment (TARA) model, which predicts that the negative associations between anxious and avoidant attachment on one hand and relationship satisfaction and commitment on the other will be more negative as relationship durations increase. Meta-analyses largely confirmed that negative associations between both insecure attachment dimensions and both relationship outcomes were more negative among longer relationship durations in cross-sectional samples. We also explored gender differences in these associations. The present review not only integrates the literature on adult attachment and romantic relationship satisfaction/commitment but also highlights the importance of relationship duration as a key moderator of the associations among these variables. We discuss the broad implications of these effects and our meta-analytic findings for the TARA model, attachment theory, and romantic relationships.

  7. THERMOPHILE ENDOSPORES HAVE RESPONSIVE EXOSPORIUM FOR ATTACHMENT

    Recently studies examining the colonization of Clostridial pathogens on agar and human tissue culture cells, demonstrated that (C. sporogenes ATCC 3584, C. difficile ATCC 43594 [patient isolate], C. difficile ATCC 9689 [non-clinical], C. clostridioforme [patient isolate]) bacterial spores (endospores) of the genus Clostridia have an outer membrane that becomes responsive at activation and exhibits extensions of the exosporial membrane that facilitate and maintain spore attachment to a nutritive substrate during germination and initial outgrowth of the newly developed bacterial cell. Therefore this attachment phenomenon plays an important role in insuring bacterial colonization of a surface and the initial stages of the infective process. To see if other non-clinical members of this genus also have this ability to attach to a substrate or food-source during spore germination, and how this attachment process in environmental thermophiles compares to the clinical paradigm (in relation to time sequence, exosporial membrane structure, type of attachment structures, composition of the membrane etc...), sediment samples were collected in sterile transport containers at 4 geothermal sites at Yellowstone National Park in Wyoming. Because spore forming bacteria will produce spores when conditions are unfavorable for growth, the samples were sealed and stored at 4 C. After 8 months the samples were screened for the presence of spores by light microscope examination using malachite green/safranin, and traditional endospores were identified in significant quantities from the Terrace Spring site (a 46 C lake with bacterial mats and a rapidly moving run-off channel leading to a traditional hot spring). The highest spore population was found in the top sediment and benthic water of the run-off channel, pH 8.1.

    1993-07-01

    Traditionally, an excess of interpersonal dependency has been used to characterize disturbed interpersonal relationships in adults. This approach stands in sharp contrast to that of attachment theorists who conceptualize attachment as functionally distinct from dependency. Attachment theory focuses on anxious attachment in the definition and dynamics of disturbed adult interpersonal relationships. The purpose of this study was to examine the relevance of anxious attachment to the differentiation of psychiatric outpatients from nonpatients. Empirically, three scales (feared loss of the attachment figure, proximity seeking, and separation protest) measure the components of anxious attachment as defined by Bowlby. The scales were administered to two research samples. Sample 1 was composed of 136 respondents to a survey within the Calgary community. Sample 2 consisted of 110 psychiatric outpatients drawn from the psychotherapy clinic of the Calgary General Hospital. The results indicate that the three components of anxious attachment offer a clinically relevant system for differentiating between psychiatric outpatients and nonpatients. Of these three components, feared loss has the predominant effect. The implications of this finding for the delineation of disturbed interpersonal relationships in adults is discussed.

    1998-12-01

    This study examined the parental correlates of child attachment in a preschool-aged, economically disadvantaged, urban, African American sample. Sixty-nine 4- to 5-year-olds and their primary caregivers participated in the Strange Situation assessment procedure. Based on Cassidy and Marvin's classification system for preschoolers, 61% of the children were classified as securely attached, with girls being significantly more likely to be securely attached than boys (74% versus 45%). The majority of the insecure attachments were of the avoidant variety. Consistent with attachment theory, parents of securely attached children were rated as significantly more warm and accepting and less controlling with their children than were parents of insecurely attached preschoolers. Relative to parents of securely attached preschoolers, parents of children judged to be insecurely attached reported being more likely to use corporal punishment and less likely to use verbal reminders when their children misbehaved. Parenting was associated with attachment over and above the effects of child sex. PMID:9914645

    Full Text Available The role of Defensive exclusion (Deactivation and Segregated Systems in the development of early relationships and related to subsequent manifestations of symptoms of eating disorders was assessed using the Adult Attachment Projective Picture System (AAP. Fifty-one DSM-IV diagnosed women with anorexia participated in the study. Anorexic patients were primarily classified as dismissing or unresolved. Quantitative and qualitative analyses of defensive exclusion were carried out. Results showed potential benefits of using the AAP defense exclusion coding system, in addition to the main attachment classifications, in order to better understand the developmental issues involved in anorexia. Discussion concerned the processes, such as pathological mourning, that may underlie the associations between dismissing and unresolved attachment and anorexia. Implications for developmental research and clinical nosology are discussed.

    2013-01-01

    Full Text Available This paper summarizes findings and clinical implications of research on attachment disorganization in diverse clinical groups. Disorganized/unresolved attachment is overrepresented in these groups compared to healthy control participants, but disorder specific characteristics of this attachment pattern are still poorly understood. The focus of this study was to explore defensive processes in participants whose narratives were classified as disorganized/unresolved using the Adult Attachment Projective Picture System (AAP. Besides the predominance of disorganized attachment, clinical participants demonstrated more “segregated system material” especially in stories representing aloneness and more “Personal Experience material” compared to healthy individuals. Within the disorganized/ unresolved clinical individuals, BPD and PTSD patients showed the highest proportion of attachment disorganization and were less able to use other attachment-related defenses to maintain organized. Furthermore, PTSD patients were emotionally overwhelmed by the projective attachment scenes compared to the other clinical groups as indexed by an incapacity to complete sections of the AAP. BPD and addicted patients were characterized by a high degree of self-other boundary confusion. Depressive and schizophrenic patients showed a high overall defensive intensity to remain organized.

    A recent advance in nanotechnology is the scale-up production of small and nonaggregated diamond nanoparticles suitable for biological applications. Using detonation nanodiamonds (NDs) with an average diameter of ∼4 nm as the adsorbents, we have studied the static attachment of three proteins (myoglobin, bovine serum albumin, and insulin) onto the nanoparticles by optical spectroscopy, mass spectrometry, and dynamic light scattering, and electrophoretic zeta potential measurements. Results show that the protein surface coverage is predominantly determined by the competition between protein-protein and protein-ND interactions, giving each protein a unique and characteristic structural configuration in its own complex. Specifically, both myoglobin and bovine serum albumin show a Langmuir-type adsorption behavior, forming 1:1 complexes at saturation, whereas insulin folds into a tightly bound multimer before adsorption. The markedly different adsorption patterns appear to be independent of the protein concentration and are closely related to the affinity of the individual proteins for the NDs. The present study provides a fundamental understanding for the use of NDs as a platform for nanomedical drug delivery. PMID:25815400

    In accordance with attachment theory, the present study investigates whether internal working models of attachment mediated the association between childhood memories and satisfaction about life in adulthood. A convenient sample of 437 participants completed questionnaires assessing a broad range of childhood memories, working models of attachment and life satisfaction. After controlling for demographics, relational status and living condition, Baron and Kenny's mediation criteria were met for the association between memories about childhood, adult attachment and life satisfaction. That is, family warmth and harmony and parental support were associated with attachment security while parental rejection and adverse childhood events (e.g., abuse, parental psychopathology) were associated with an insecure attachment style. More securely attached individuals were in turn more satisfied about their current life than insecurely attached individuals. Sobel test confirmed these findings. These finding are in accordance with attachment theory and highlight the importance of this theory for understanding how early childhood experiences may impact adult life. PMID:19165809

    This study explored the compatibility between the current Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV-TR) diagnostic criteria for alcohol abuse and dependence with the initial (DSM-5.0) and most recent (DSM-5.1) proposed diagnostic criteria. Data drawn from a structured clinical interview used in the assessment of 6,871 male and 801 female state prison inmates were analyzed according to the existing and proposed diagnostic formulations. The greatest congruence was observed in cases that received no diagnosis according to the DSM-IV-TR because these also received no diagnosis in the DSM-5.1. Most cases with a current dependence diagnosis received a severe designation according to the proposed criteria. However, those with an abuse diagnosis were divided across various DSM-5.1 severity levels. Some diagnostic criteria were nearly universally endorsed among those classified with the highest severity levels, which indicated that some criteria may serve as cardinal indicators of a severe alcohol use disorder (SAUD). Additional diagnostic criteria not yet suggested for inclusion in the DSM (i.e., preoccupation with alcohol use and alcohol use to relieve emotional distress) were also evaluated. Evidence demonstrated these two criteria served as functional indicators of alcohol use disorder (AUD). This assessment approach can be used to establish appropriate treatment objectives based on the severity of diagnosed AUDs. Meeting these treatment objectives, especially in a correctional population, may have important implications for future offending. Recommendations are made for prospective research in this area.

A clinical group of subjects with perinatal depression (PND, 89 subjects was selected and compared with a control group (C, regarding psychopathological variables and attachment patterns. Results. The ECR showed a prevalence of “Fearful-Avoidant” attachment style in PND group (29.2% versus 1.1%, p<0.001; additionally, the EPDS average score increases with the increasing of ECR dimensions (Avoidance and Anxiety. Conclusion. The severity of depression increases proportionally to attachment disorganization; therefore, we consider attachment as both an important risk factor as well as a focus for early psychotherapeutic intervention.

    Neustadt, Elizabeth A; Chamorro-Premuzic, Tomas; Furnham, Adrian

    2011-09-01

    This paper examines the relations between self-reported attachment orientation at work and personality, self-esteem, trait emotional intelligence (aka emotional self-efficacy), and independently assessed career potential and job performance. Self-report data were collected from 211 managers in an international business in the hospitality industry; independent assessments of these managers' job performance and career potential were separately obtained from the organization. A self-report measure of romantic attachment was adapted for application in the work context; a two-factor solution was found for this measure. Secure/autonomous attachment orientation at work was positively related to self-esteem, trait emotional intelligence, extraversion, agreeableness, and conscientiousness, and also to job performance. Not only was secure/autonomous attachment orientation at work statistically predictive of job performance, but the new measure also made a distinct contribution, beyond conscientiousness, to this prediction.

    2016-03-01

    Full Text Available The extent to which we engage with our social world has been central to our survival as a species and, accordingly, is relevant to how we cope with trauma and adversity. This review summarises current knowledge about the importance of social connections from an evolutionary perspective, as well as integrating this with a discussion of prevailing attachment theories. Experimental research supporting the potential benefit of attachments for managing adversity are presented, along with a review of how these benefits are moderated by individual differences in attachment style. The potential impact of trauma on attachment systems, and the manner in which this can compound trauma stress is discussed. Finally, a broader overview of social network analysis is introduced and it is proposed that a more sociocentric framework of trauma response would promote a fuller understanding of how social processes moderate trauma response.

  13. Electron attachment to fluorocarbon radicals

    Science.gov (United States)

    Shuman, Nicholas

    2014-10-01

    Most plasma environments contain populations of short-lived species such as radicals, the chemistry of which can have significant effects on the overall chemistry of the system. However, few experimental measurements of the kinetics of electron attachment to radicals exist due to the inherent difficulties of working with transient species. Calculations from first principles have been attempted, but are arduous and, because electron attachment is so sensitive to the specifics of the potential surface, their accuracy has not been established. Electron attachment to small fluorocarbon radicals is particularly important, as the data are needed for predictive modeling of plasma etching of semiconductor materials, a key process in the industrial fabrication of microelectronics. We have recently developed a novel flowing afterglow technique to measure several types of otherwise difficult to study plasma processes, including thermal electron attachment to radicals. Variable Electron and Neutral Density Attachment Mass Spectrometry (VENDAMS) exploits dissociative electron attachment in a weakly ionized plasma as a radical source. Here, we apply VENDAMS to a series of halofluorocarbon precursors in order to measure the kinetics of thermal electron attachment to fluorocarbon radicals. Results are presented for CF2, CF3, C2F5,C2F3,1-C3F7, 2-C3F7, and C3F5 from 300 K to 900 K. Both the magnitude and the temperature dependences of rate coefficients as well as product branching between associative and dissociative attachment are highly system specific; however, thermal attachment to all species is inefficient, never exceeding 5% of the collision rate. The data are analyzed using a recently developed kinetic modeling approach, which uses extended Vogt-Wannier theory as a starting point, accounts for dynamic effects such as coupling between the electron and nuclear motions through empirically validated functional forms, and finally uses statistical theory to determine the fate of

    Bakermans-Kranenburg, Marian J; van IJzendoorn, Marinus H

    2009-05-01

    More than 200 adult attachment representation studies, presenting more than 10,500 Adult Attachment Interview (AAI; George, Kaplan, & Main, 1985) classifications, have been conducted in the past 25 years. In a series of analyses on the distributions of the AAI classifications in various cultural and age groups, fathers, and high-risk and clinical samples, we used the distribution of the combined samples of North American non-clinical mothers (23% dismissing, 58% secure, 19% preoccupied attachment representations, and 18% additionally coded for unresolved loss or other trauma) to examine deviations from this normative pattern, through multinomial tests and analyses of correspondence. The analyses were restricted to AAI classifications coded according to the Main, Goldwyn, and Hesse (2003) system. We did not find gender differences in the use of dismissing versus preoccupied attachment strategies, and the AAI distributions were largely independent of language and country of origin. Clinical subjects showed more insecure and unresolved attachment representations than the norm groups. Disorders with an internalizing dimension (e.g., borderline personality disorders) were associated with more preoccupied and unresolved attachments, whereas disorders with an externalizing dimension (e.g., antisocial personality disorders) displayed more dismissing as well as preoccupied attachments. Depressive symptomatology was associated with insecurity but not with unresolved loss or trauma, whereas adults with abuse experiences or PTSD were mostly unresolved. In order to find more reliable associations with clinical symptoms and disorders, future AAI studies may make more fruitful use of continuous AAI scales in addition to the conventionally used categorical classifications.

  20. Phenotypes of non-attached Pseudomonas aeruginosa aggregates resemble surface attached biofilm.

    Directory of Open Access Journals (Sweden)

    Morten Alhede

    Full Text Available For a chronic infection to be established, bacteria must be able to cope with hostile conditions such as low iron levels, oxidative stress, and clearance by the host defense, as well as antibiotic treatment. It is generally accepted that biofilm formation facilitates tolerance to these adverse conditions. However, microscopic investigations of samples isolated from sites of chronic infections seem to suggest that some bacteria do not need to be attached to surfaces in order to establish chronic infections. In this study we employed scanning electron microscopy, confocal laser scanning microscopy, RT-PCR as well as traditional culturing techniques to study the properties of Pseudomonas aeruginosa aggregates. We found that non-attached aggregates from stationary-phase cultures have comparable growth rates to surface attached biofilms. The growth rate estimations indicated that, independently of age, both aggregates and flow-cell biofilm had the same slow growth rate as a stationary phase shaking cultures. Internal structures of the aggregates matrix components and their capacity to survive otherwise lethal treatments with antibiotics (referred to as tolerance and resistance to phagocytes were also found to be strikingly similar to flow-cell biofilms. Our data indicate that the tolerance of both biofilms and non-attached aggregates towards antibiotics is reversible by physical disruption. We provide evidence that the antibiotic tolerance is likely to be dependent on both the physiological states of the aggregates and particular matrix components. Bacterial surface-attachment and subsequent biofilm formation are considered hallmarks of the capacity of microbes to cause persistent infections. We have observed non-attached aggregates in the lungs of cystic fibrosis patients; otitis media; soft tissue fillers and non-healing wounds, and we propose that aggregated cells exhibit enhanced survival in the hostile host environment, compared with non

    Background: In the present study, we have explored the link among styles of attachment and psychopathology in drug users. We know that insecure attachment predisposes the individuals the development of drug-addiction and psychopathological symptoms. However, we do not know which attachment is more frequent in drug users and which is related to particular psychopathological symptoms. The aim of the present work is to explore the relationship between childhood attachment state of mind, attachment in close relationships, parental bonding and psychopathology in sample of Italian substance users. Methods: We explored, in a sample of 70 drug users and drug-addicted patients, the childhood attachment state of mind measured by the Adult Attachment Interview, the attachment in close relationships by the Relationship Questionnaire and parental bonding measured by the Parental Bonding Instrument. The Symptom Check-List-90-R (SCL-90-R) measured psychopathological symptoms. Results: We found that parental bonding, rather than state of mind concerning childhood attachment or attachment in close relationships, is related to the psychopathological manifestation of anxiety, hostility, depression, and paranoid ideation in the sample. The latter occurs frequently in our sample, independent of state of mind concerning child attachment, attachment in close relationships, and parental bonding, suggesting its role either as a factor that favors a bad image of the participants’ own relationships or as a direct effect of consuming drugs. Conclusion: These results have clinical implications on suggesting ways of interventions that prevent drug-addiction, which should include the evaluation of attachment in the prodromic phases of substance use onset or rehabilitation programs to prevent and manage psychotic-like symptoms.

    The Adult Attachment Interview is a semi-structured interview developed to investigate adults' attachment representations. Subjects are asked to describe their parents as caregivers, explain these descriptions, describe how their parents typically responded to distress, and discuss their current relationships with their parents. They are also asked to describe any significant losses and/or instances of abuse during childhood. Scoring focuses on the accessibility of early experiences to memory and the coherence and plausibility of the subject's narrative. Discriminant validity is always an important issue with such measures because IQ and other cognitively loaded variables offer plausible alternative interpretations or represent important correlates that should be treated as covariates when the measure is used. In addition, complex, multifaceted interviews always pose the risk of assessing general social adjustment rather than a more narrowly defined construct. This study examines the discriminant validity of the AAI vis(-)à-vis intelligence, social desirability, discourse style, and general social adjustment in a sample of 53 native-English-speaking, married women with preschool children. They were assessed with the AAI, a written IQ test, the Social Adjustment Scale, the Employment Experience Interview (discourse style), and a measure of social desirability. There were modest but significant correlations with IQ scores and social adjustment. There was no relation between AAI classifications and discourse style or social desirability. These results substantially strengthen the case for interpreting the AAI as an attachment-related measure.

    2013-01-01

    Previous research has related maternal anxiety to insecurity of attachment. Here we ask whether different aspects of maternal sensitivity mediate this link. From a community sample of intact families with 1-3 children, mothers with 4.5-year-olds were selected for low, medium, or high anxiety levels (N = 98). Following Mary Ainsworth's lead, our maternal sensitivity measures were primarily based on ratings of direct observations. Six sets of measures were obtained: positive maternal style at home (a mean of four different ratings); providing a sensitive framework, limit setting, allowing autonomy, criticizing/cutting in (each a mean over two laboratory joint tasks); and tension-making (a mean of three different ratings in a fear-inducing task). Regression analyses showed firstly that maternal anxiety rather than behavioral inhibition or sex of child was the significant predictor of each maternal sensitivity measure; and secondly that these measures rather than maternal anxiety or sex were the significant predictors of security of attachment. Finally, ANOVA's indicated which sets of maternal ratings were associated with each pattern of attachment (Avoidant, Secure, Ambivalent, or Controlling).

    Bryant, Richard A; Foord, Rachael

    2016-01-01

    Emotional memories, and especially intrusive memories, are a common feature of many psychological disorders, and are overconsolidated by stress. Attachment theory posits that activation of mental representations of attachment figures can reduce stress and boost coping. This study tested the proposition that attachment activation would reduce consolidation of emotional and intrusive memories. Sixty-seven undergraduate students viewed subliminal presentations of traumatic and neutral images, which were preceded by subliminal presentations of either attachment-related images or non-attachment-related images; free recall and intrusive memories were assessed two days later. Participants with low avoidant attachment tendencies who received the attachment primes recalled fewer memories and reported fewer intrusions than those who received the non-attachment primes. Unexpectedly, those with high anxious attachment tendencies reported fewer memories. These findings generally accord with attachment theory, and suggest that consolidation of emotional memories can be moderated by activation of attachment representations. PMID:27631498

    The preparation, characterization, and surface modification of upconverting lanthanide-doped hexagonal NaGdF4 nanocrystals attached to light sensitive diiodido-Pt(IV) complexes is presented. The evaluation for photoactivation and cytotoxicity of the novel carboxylated diiodido-Pt(IV) cytotoxic prodrugs by near-infrared (NIR) light (λ = 980 nm) is also reported. We attempted two different strategies for attachment of light-sensitive diiodido-Pt(IV) complexes to Yb,Er- and Yb,Tm-doped β-NaGdF4 upconverting nanoparticles (UCNPs) in order to provide nanohybrids, which offer unique opportunities for selective drug activation within the tumor cells and subsequent spatiotemporal controlled drug release by NIR-to-visible light-upconversion: (A) covalent attachment of the Pt(IV) complex via amide bond formation and (B) carboxylate exchange of oleate on the surface of the UCNPs with diiodido-Pt(IV) carboxylato complexes. Initial feasibility studies showed that NIR applied by a 980 nm laser had only a slight effect on the stability of the various diiodido-Pt(IV) complexes, but when UCNPs were present more rapid loss of the ligand-metal-charge transfer (LMCT) bands of the diiodido-Pt(IV) complexes was observed. Furthermore, Pt released from the Pt(IV) complexes platinated calf-thymus DNA (ct-DNA) more rapidly when NIR was applied compared to dark controls. Of the two attachment strategies, method A with the covalently attached diiodido-Pt(IV) carboxylates via amide bond formation proved to be the most effective method for generating UCNPs that release Pt when irradiated with NIR; the released Pt was also able to bind irreversibly to calf thymus DNA. Nonetheless, only ca. 20% of the Pt on the surface of the UCNPs was in the Pt(IV) oxidation state, the rest was Pt(II), indicating chemical reduction of the diiodido-Pt(IV) prodrug by the UCNPs. Cytotoxicity studies with the various UCNP-Pt conjugates and constructs, tested on human leukemia HL60 cells in culture, indicated a

    2015-01-01

    Prediction and control of network dynamics are grand-challenge problems in network science. The lack of understanding of fundamental laws driving the dynamics of networks is among the reasons why many practical problems of great significance remain unsolved for decades. Here we study the dynamics of networks evolving according to preferential attachment, known to approximate well the large-scale growth dynamics of a variety of real networks. We show that this dynamics is Hamiltonian, thus casting the study of complex networks dynamics to the powerful canonical formalism, in which the time evolution of a dynamical system is described by Hamilton's equations. We derive the explicit form of the Hamiltonian that governs network growth in preferential attachment. This Hamiltonian turns out to be nearly identical to graph energy in the configuration model, which shows that the ensemble of random graphs generated by preferential attachment is nearly identical to the ensemble of random graphs with scale-free degree d...

  15. Studies of binary cerium(IV)-praseodymium(IV) and cerium(IV)-terbium(IV) oxides as pigments for ceramic applications

    International Nuclear Information System (INIS)

    It was investigated a series of pigments of general composition Ce1-x Prx O2, and Cex Tby O2, exhibiting radish and brown colors, respectively, and high temperature stability. The pigments were obtained by dissolving appropriate amounts of the pure lanthanide oxides in acids and precipitating the rare earths as mixed oxalates, which were isolated and calcined under air, at 10000 C. X-Ray powder diffractograms were consistent with a cubic structure for the pigments. Magnetic susceptibility measurements, using Gouy method, indicated the presence of Pr(IV) ions in the Ce1-x Prx O2 pigments and of Terbium predominantly as Tb(III) ions in the Ce-tb mixed oxides. A new method, based on suspension of solid samples in PVA-STB gels (STB = sodium tetradecaborate), was employed for the measurements of the electronic spectra of the pigments. The thermal behaviour the pigments was investigated by the calcination of the oxalates in the temperature range of 500 to 1200O C, from 10 to 60 minutes. (author)

A new attachment, the Locator, which features a reduced interarch requirement and the advantage of built-in guide planes providing precise insertion, is described. The Locator is an advancement in attachment technology, with an improved design combined from the best features of a ball attachment, an ERA attachment, and a cap attachment.

    Full Text Available ABSTRACT: A unique concern of a removable denture when compare d to others is retention. Retention is the ability of the prosthesis to resist the movement of denture away from the supporting tissues/teeth. The component of removable d enture which provides retention is called as direct retainer. 1,3,4 A direct retainer can be either an extracoronal or intracoronal retainer. Extracoronal direct retainer uses mechanical resistance to displa cement through components placed on external surface of abutment teeth. Intracoronal retainer is either cast or attached to tally within the restored natural contours of an abutment tooth. 1 One of the main drawbacks of extracoronal retainers used in partial dentures is visibility. Many patients find themselves in an aest hetically compromised state when these retainers are placed on teeth in visible area. Preci sion attachments provide solution for this problem. Also, precision attachments provide better ve rtical support and better stimulation to the underlying tissue through intermittent vertical massage. 1,9 Although the history of intracoronal retainers goes back to 5 th and 4 th centuries BC, technically more sound developments began in early 2 0 th century AD, with Dr. Herman E. S. Chayes formulating the principle of internal attachme nt in 1906. Since then precision attachments are playing an important role in removabl e and fixed partial denture, conventional and implant supported overdenture. 9

    The dermal-epidermal junction of skin contains extracellular matrix proteins that are involved in initiating and controlling keratinocyte signaling events such as attachment, proliferation, and terminal differentiation. To characterize the relationship between extracellular matrix proteins and keratinocyte attachment, a biomimetic design approach was used to precisely tailor the surface of basal lamina analogs with biochemistries that emulate the native biochemical composition found at the dermal-epidermal junction. A high-throughput screening device was developed by our laboratory that allows for the simultaneous investigation of the conjugation of individual extracellular matrix proteins (e.g. collagen type I, collagen type IV, laminin, or fibronectin) as well as their effect on keratinocyte attachment, on the surface of an implantable collagen membrane. Fluorescence microscopy coupled with quantitative digital image analyses indicated that the extracellular matrix proteins adsorbed to the collagen-GAG membranes in a dose-dependent manner. To determine the relationship between extracellular matrix protein signaling cues and keratinocyte attachment, cells were seeded on protein-conjugated collagen-GAG membranes and a tetrazolium-based colorimetric assay was used to quantify viable keratinocyte attachment. Our results indicate that keratinocyte attachment was significantly enhanced on the surfaces of collagen membranes that were conjugated with fibronectin and type IV collagen. These findings define a set of design parameters that will enhance keratinocyte binding efficiency on the surface of collagen membranes and ultimately improve the rate of epithelialization for dermal equivalents.

    Aqueous complexation of Th(IV), U(IV), Np(IV), Pu(III/IV), and Ce(III/IV) with DTPA was studied by potentiometry, absorption spectrophotometry, and cyclic voltammetry at 1 M ionic strength and 25 °C. The stability constants for the 1:1 complex of each trivalent and tetravalent metal were calculated. From the potentiometric data, we report stability constant values for Ce(III)DTPA, Ce(III)HDTPA, and Th(IV)DTPA of log β(101) = 20.01 ± 0.02, log β(111) = 22.0 ± 0.2, and log β(101) = 29.6 ± 1, respectively. From the absorption spectrophotometry data, we report stability constant values for U(IV)DTPA, Np(IV)DTPA, and Pu(IV)DTPA of log β(101) = 31.8 ± 0.1, 32.3 ± 0.1, and 33.67 ± 0.02, respectively. From the cyclic voltammetry data, we report stability constant values for Ce(IV) and Pu(III) of log β(101) = 34.04 ± 0.04 and 20.58 ± 0.04, respectively. The values obtained in this work are compared and discussed with respect to the ionic radius of each cationic metal.

    We present optical and near infrared spectroscopy obtained at Keck, VLT, and Gemini for a sample of 36 secure strong gravitational lens systems and 17 candidates identified as part of the SL2S survey. The deflectors are massive early-type galaxies in the redshift range z_d=0.2-0.8, while the lensed sources are at z_s=1-3.5. We combine this data with photometric and lensing measurements presented in the companion paper III and with lenses from the SLACS and LSD surveys to investigate the cosmic evolution of the internal structure of massive early-type galaxies over half the age of the universe. We study the dependence of the slope of the total mass density profile \\gamma' (\\rho(r)\\propto r^{-\\gamma'}) on stellar mass, size, and redshift. We find that two parameters are sufficent to determine \\gamma' with less than 6% residual scatter. At fixed redshift, \\gamma' depends solely on the surface stellar mass density \\partial \\gamma'/ \\partial \\Sigma_*=0.38\\pm 0.07, i.e. galaxies with denser stars also have steeper ...

    The aim of this research is to explore the extent to which employees establish attachment bonds with their leaders and the effects these bonds have on organizational outcomes. A sample of 225 participants reported on their supervisor's leadership style (transformational, transactional, or passive-avoidant), their attachment bonds to this supervisor (anxious or avoidant), and four organizational variables (subordinate's satisfaction, identification with the organization, extra effort, and perceived leadership effectiveness). Results, analyzed using a Partial Least Squares (PLS) approach, indicated that (a) transformational leadership was negatively associated with employees' insecure (anxious or avoidant) attachment to their leader; (b) passive/avoidant leadership was positively associated with subordinates' insecure attachment to their leader; (c) transactional leadership was positively associated with employee's anxious attachment but not with their avoidant attachment; (d) avoidant, but not anxious, attachment to the leader was negatively associated with employee satisfaction, perceived leader effectiveness, employee's extra effort, and organizational identification.

    The following can be concluded from the research conducted on the treatment of Lurgi process wastewaters from the sample sent to Sasol: Biooxidation of pretreated gas liquors and synthesized Mobil MTG process wastewater components as feasible and a high degree of treatment efficiency could be attained when the process was controlled by optimizing the growth of thiocyanate bacteria. Sludge settleability was satisfactory. Partial removal of complexed cyanide was consistently maintained during steady-state operation of the bioreactor, probably by sorption on the biofloc. Seed sludges from a coke oven activated sludge process can be successfully used to develop biocultures for the treatment of Lurgi process wastewaters. GAC treatment was effective for the removal of residual organic carbon and chemical oxygen demand from bioreactor treated effluents. Untreated gas liquor was extremely toxic to fathead minnows at effluent concentrations of only five percent (19 parts water to one part gas liquor). However, bioreactor effluent showed a greatly reduced toxicity, with significant mortalities between 40 and 60 percent (approximately one part water to one part effluent). Treatment with granular activated carbon (GAC) reduced toxicity to negligible levels, even with relatively high unionized ammonia levels present in the effluent. No toxic effects were observed with GAC effluents when the pH was adjusted to reduce unionized ammonia levels. Bioassay test results demonstrated that the treated effluents after activated carbon adsorption would be relatively nontoxic to fathead minnows. Biological wastewater treatment facilities installed to meet BPT for Lurgi wastewater should provide sufficient removal of most toxic organic pollutants which would be designated as BAT.

    Full Text Available In the present article we review findings from an emerging body of research on attachment issues in adolescents with eating disorders from a developmental perspective. First, we will outline the crucial developmental changes in the attachment system and discuss how they might be related to the early onset of the disease. Then we will report on the major results from attachment studies using self-report and narrative instruments in that age group. Studies with a developmental approach on attachment will be analyzed in more detail. The high incidence of the unresolved attachment pattern in eating disorder samples is striking, especially for patients with anorexia nervosa. Interestingly, this predominance of the unresolved category was also found in their mothers. To date, these transgenerational aspects are still poorly understood and therefore represent an exciting research frontier. Future studies that include larger adolescent samples and provide a more detailed description including symptom severity and comorbidity would contribute to a better understanding of this complex and painful condition.

    Science.gov (United States)

    Bartholomew, K

    1997-09-01

    This paper overviews a new approach to understanding the range of difficulties experienced in close attachment relationships in adulthood. Drawing on the work of Bowlby, four prototypic adult attachment patterns are defined in terms of the intersection of two underlying dimensions, the positivity of the person's self-image and the positivity of the person's image of others (Bartholomew, 1990; Bartholomew & Horowitz, 1991). The distinct interpersonal difficulties associated with each attachment pattern are described. Findings are presented indicating that individual differences in attachment have implications for the quality of adults' romantic relationships, and that attachment theory may be helpful in understanding violent spousal relationships. Five current issues in the study of adult attachment are addressed: the stability of attachment patterns, the associations between attachment and general personality factors, the relative merits of categorical and prototype assessments of attachment, the identification of multiple attachments in adulthood, and the specificity of adult attachment patterns. It is suggested that the four-category model of adult attachment is especially sensitive to the range and complexity of attachment-related difficulties experienced in adulthood.

    Full Text Available From a developmental and clinical point of view attachment theory and mentalization are closely connected and have become increasingly important to understand the origins of psychopathological development. However, very little is known about how exactly different inner working models of attachment are related to diverse mentalizing abilities and this is particularly true for adult populations - healthy as well as clinical populations. In the present study we investigated this relation with a sample of inpatients diagnosed with depression and a sample of healthy individuals. In an experimental setting the attachment system was activated using the Adult Attachment Projective Picture System (AAP. Mentalization was assessed during activation and in comparison to a control condition using a modified version of the Reading the Mind in the Eyes Test (RMET. We expected that an activation of the attachment system i diminishes the capacity to take another’s perspective in individuals with unresolved state of mind, ii has no impact in individuals with secure attachment representation and iii is dependent of clinical status in individuals with insecure (but organized working models of attachment. Overall, these hypotheses were confirmed. However, the impact of clinical status on mentalization in insecure attachment has to be further explored. We summarize that attachment state of mind has a mediating influence on mentalization basically in such situations where the attachment system is activated.

    Although the majority of foster children have been exposed to early adversity in their biological families and have experienced one or more disruptions of attachment relationships, most studies surprisingly found foster children to be as securely attached as children in low-risk samples. However, attention has been paid almost exclusively to attachment formation in young children up to two years of age, and the majority of studies solely investigated attachment behavior whereas few is known about foster children's representations about attachment relationships. To extend findings on attachment in foster children and its predictors, our study examined both attachment behavior and representations in foster children aged between 3 and 8 years. Diverse potential predictors including child variables, birth parents' variables, pre-placement experiences, and foster caregiver's behavior were included in the analyses. Results revealed that foster children showed both lower attachment security and higher disorganization scores than children in low-risk samples. Attachment behavior and representation were found to be widely independent from each other. Different factors contributed to attachment behavior and representation: whereas foster children's attachment behavior was mainly influenced by foster parents' behavior, pre-placement experiences did predict hyperactivation and disorganization on the representational level. The results indicate that, when intervening with foster families, it seems crucial to focus not exclusively on the promotion of secure attachment behavior but also to develop interventions enhancing secure and organized attachment representations.

    Full Text Available The nature and characteristics of the primary bonds and attachment styles wwhich are established with parental figures and / or their surrogates in the first years of life, without doubt are one of the basis and models for later relationships. Intense changes will be produce particularly during adolescence in the parental bonds and the scenario, which defines and reinforces personal autonomy to be extended. In this way, self-concept is probably one of the most researched constructs in psychological tradition if we compare it with other psychological and contextual variables. Nevertheless, a few studies explore especially the relationship between attachment and self-concept in adolescents. The aim of this empirical study was to analyze the relationship between attachment styles and self-concept dimensions in adolescents, from a salutogenic approach in order to identify if certain attachment characteristics are associated with more positive aspects of self-concept. A sample of 583 adolescents aged 15- 18 years from public and private schools in Mar del Plata completed the AF5 and IPPA scales. Significant positive relationships were confirmed between secure attachment style and self- concept dimensions. These results provide empirical support to advance in the research about which characteristics are specifically related to positive and healthy development in adolescents.

    Existing literature on the role of religiosity in marital functioning is often difficult to interpret due to the frequent use of convenience samples, statistical approaches inadequate for interdependent dyadic data, and the lack of a theoretical framework. The current study examined the effects of religious commitment and insecure attachment on marital adjustment. Newly married couples who did not have children (N = 92 couples, 184 individuals) completed measures of religious commitment, adult attachment, and marital functioning. There was a small positive association between religious commitment and marital adjustment. Religious commitment buffered the negative association between attachment avoidance and marital adjustment, but exacerbated the negative association between attachment anxiety and marital adjustment.

  8. Effect of hot water spray on broiler carcasses for reduction of loosely attached, intermediately attached, and tightly attached pathogenic (Salmonella and Campylobacter) and mesophilic aerobic bacteria.

    Chickens are known to harbor many bacteria, including pathogenic microorganisms such as Salmonella and Campylobacter. The objective of this study was to evaluate the efficacy of hot water spray (HWS, 71°C for 1 min) in reducing bacterial contamination of prechilled broiler carcasses. For each of 4 replications, skin samples from 5 broilers were collected at 3 processing stages: after bleeding (feathers removed manually), after evisceration (with/without HWS), and after water chilling. Broiler skin was quantitatively assessed for loosely attached (by rinsing the skin), intermediately attached (by stomaching the rinsed skin), and tightly attached (by grinding the rinsed/stomached skin) mesophilic aerobic bacteria (MAB) and Campylobacter as well as for the prevalence of Salmonella and Campylobacter. Broiler skins possessed 6.4 to 6.6 log cfu/g, 3.8 to 4.1 log cfu/g, and 2.8 to 3.5 log cfu/g of MAB populations after bleeding, evisceration, and chilling, respectively. The HWS resulted in more than 1 log unit of reduction in MAB immediately after evisceration and immediately after chilling regardless of microbial sampling method. Compared with MAB, the contamination of Campylobacter was low (1.7 to 2.6 log cfu/g) after bleeding, but the level was not reduced throughout the processing steps regardless of HWS. The application of HWS reduced the prevalence of Salmonella after chilling, but not for Campylobacter except for loosely attached cells. After hot water exposure, a partially cooked appearance was seen on both broiler skin and skinless breast surface. More research is required to effectively eliminate pathogenic organisms during processing and suppress any recovery of bacteria regardless of attachment type after chilling.

    Microbial contamination of carcass surfaces occurs during slaughter and post-slaughter processing steps, therefore interventions are needed to enhance meat safety and quality. Although many studies have been done at the macro-level, little is known about specific processes that influence bacterial attachment to carcass surfaces, particularly the role of extracellular matrix (ECM) proteins. In the present study, the effect of pH and salt (NaCl, KCl and CaCl2) on attachment of Escherichia coli and Salmonella isolates to dominant ECM proteins: collagen I, fibronectin, collagen IV and laminin were assessed. Also, the effects of three chemical rinses commonly used in abattoirs (2% acetic acid, 2% lactic acid and 10% trisodium phosphate (TSP)) were tested. Within a pH range of 5-9, there was no significant effect on attachment to ECM proteins, whereas the effect of salt type and concentration varied depending on combination of strain and ECM protein. A concentration-dependant effect was observed with NaCl and KCl (0.1-0.85%) on attachment of E. coli M23Sr, but only to collagen I. One-tenth percent CaCl2 produced the highest level of attachment to ECM proteins for E. coli M23Sr and EC614. In contrast, higher concentrations of CaCl2 increased attachment of E. coli EC473 to collagen IV. Rinses containing TSP produced >95% reduction in attachment to all ECM proteins. These observations will assist in the design of targeted interventions to prevent or disrupt contamination of meat surfaces, thus improving meat safety and quality.

    Clinicians can use the base rates of low scores in healthy people to reduce the likelihood of misdiagnosing cognitive impairment. In the present study, base rates were developed for the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) and Wechsler Memory Scale-Fourth Edition (WMS-IV) using 900 healthy adults and validated on 28 patients with moderate or severe traumatic brain injuries (TBIs). Results indicated that healthy people obtain some low scores on the WAIS-IV/WMS-IV, with prevalence rates increasing with fewer years of education and lower predicted intelligence. When applying the base rates information to the clinical sample, the TBI patients were 13 times more likely to be identified as having a low cognitive profile compared with the controls. Using the base rates information is a psychometrically advanced method for establishing criteria to determine low cognitive abilities on the WAIS-IV/WMS-IV.

    2011-01-01

    Although the supervisory relationship is thought to be critical in training clinical psychologists, little is known about factors affecting the supervisory alliance. We conducted an Internet survey of British clinical doctoral trainees (N = 259) in which participants rated their supervisory working alliance, parental style during childhood, pathological adult attachment behaviours and attachment style for themselves and their supervisors. Trainees' ratings of the working alliance were associated with perceptions of supervisors' attachment style, but not with perceptions of trainees' own attachment styles. Path analysis supported a causal chain linking parental indifference, compulsive self-reliance, insecure supervisor attachment style and lower ratings of the working alliance. Our results broadly replicate data from a US sample and suggest that attachment theory is helpful in understanding clinical supervisory processes.

    2007-09-01

    We investigated the relationship of child attachment representation, psychopathology, and maternal atypical parenting in a high risk sample. Sixty-one consecutive clinical referrals with externalizing disorder aged 4 - 9 years were assessed for attachment representations measured with Manchester Child Attachment Story Task (MCAST), atypical parental expressed emotion (EE), maternal mood, and parent and teacher ratings of child behaviour. Disorganized attachment representations were found in 58% of cases, independent of ADHD symptoms. Pervasive disorganization was associated with very high maternal EE. Attachment status, maternal depression, and ADHD diagnosis were independently associated with parent-rated child behaviour problems; teacher ratings were associated with child's age and ADHD status. Disorganized attachment shows a high prevalence and independent associations with attention deficit symptomatology and maternal EE.

    Not all Phase IV studies are post-marketing surveillance (PMS) studies but every PMS study is a phase IV study. Phase IV is also an important phase of drug development. In particular, the real world effectiveness of a drug as evaluated in an observational, non-interventional trial in a naturalistic setting which complements the efficacy data that emanates from a pre-marketing randomized controlled trial (RCT). No matter how many patients are studied pre-marketing in a controlled environment, the true safety profile of a drug is characterized only by continuing safety surveillance through a spontaneous adverse event monitoring system and a post-marketing surveillance/non-interventional study. Prevalent practice patterns can generate leads that could result in further evaluation of a new indication via the RCT route or even a signal that may necessitate regulatory action (change in labeling, risk management/minimization action plan). Disease registries are another option as are the large simple hybrid trials. Surveillance of spontaneously reported adverse events continues as long as a product is marketed. And so Phase IV in that sense never ends.

    Full Text Available The asymmetric unit of the title organotin salt, (C8H20N[Sn(C6H53(CH4O3P2], contains two dibutylammonium cations and two stannate(IV anions consisting each of two monodentately bonding methyl hydrogenphosphate groups attached to an Sn(C6H5 unit. The overall coordination environment of the two SnIV atoms is trigonal–bipyramidal defined by three phenyl C atoms in equatorial positions and two methyl hydrogenphosphate O atoms at the apical sites. In the crystal, the stannate(IV anions are linked to each other via pairs of short O—H...O hydrogen bonds, leading to an infinite chain extending parallel to the b-axis direction. Neighbouring chains are linked by N—H...O hydrogen bonds involving the butylammonium cations, giving a two-dimensional structure parallel to the ab plane. The crystal under investigation was found to be twinned by reticular merohedry with twin fractions of 0.5342 (7:0.4658 (7.

    The aim of this study was to evaluate wear effects on overdenture resilient attachments. Six commercially available attachments were investigated: ERA orange and white (EO and EW), Locator pink, white and blue (LRP, LRW and LRB) and OP anchor (OP). Five specimens were used for wear simulation while other two specimens served as controls. Fifteen thousands insertion-removal cycles were simulated. Dimensional changes and surface characteristics were evaluated using light microscopy and SEM, respectively. Sudden decrease of retentive force was characteristic for EO and EW attachments. Retentive force of Locator attachments fluctuated throughout the wear simulation period. Dimensional changes and surface wear was more expressed on plastic cores than on plastic rings of attachment males. Based on SEM analysis, some of the specimens obtained smoother surface after wear simulation. Mechanism of retention loss of resilient overdenture attachments can be only partially explained by dimensional changes and surface alterations.

    Objective: Psychological theories have postulated an association between insecure attachment and ADHD. The objective of this study is to investigate possible association between insecure attachment and ADHD in children and adults. Method: Review of literature was performed using the Psyc......INFO, Medline, and EMBASE databases. Results: Twenty-nine studies were included in the review. Overall, the studies showed that parental attachment problems and environmental mediating factors were significantly associated with childhood ADHD. Adults with ADHD had a much higher incidence of insecure attachment...... styles than reported in the general population. Conclusion: There seems to be a clear association between ADHD and insecure attachment. It is likely that early intervention in the form of parent training and pharmacological treatment may prevent development of attachment problems. But such studies have...

    2010-01-01

    Full Text Available In this work our aim is to examine how the components of attachment influence the thinking development of adolescents in familial context. We investigated the components of attachment: unresolved family traumatisation, the use of external security base, fear of loss of external security base, negative self concept, negative other concept, capacity for mentalisation, low control of anger. We used a revised Questionnaire for Assessment of Adult and Adolescent Attachment (in original: UPIPAV-R. Formal operations were tested by Bond's Logical Operations Test. We examined the cultural-pedagogical status of the family, the parental mediation characteristic for the development of formal operations, and family property as the aspects of familial context. The sample consisted of 200 pupils aged 14 to 19. According to the attachment theory, secure attachment provides the feel of security in environment exploration, which is the ground of personality development. We assumed that components of attachment contribute formal-operational thinking development and change the influence of familial cultural-supportive tools. The findings show us that the culturalpedagogical status of the family improves formal operations development and unresolved family traumatisation has negative influence. Capacity for mentalisation has a positive indirect effect on thinking development through the influence of the cultural-pedagogical status of the family. The low control of anger has a negative indirect effect on thinking development; it increases the influence of unresolved family traumatisation. Negative self concept has indirect effects on thinking development through increasing this negative influence of unresolved family traumatisation and decreasing the role of familial cultural-supportive tools.

    Full Text Available The article is an attempt to present holistically the key concepts of attachment theory rediscovered for its potentials. The presented concepts include: narrow definition of attachment, behavioral control system of attachment, attachment working model and patterns of attachment. The concepts are presented in the context of child attachment theory and adult attachment theory, in addition to description of the development of attachment. Concepts, as well as developmental processes are presented from the stand point of pioneers in this field (John Bowlby and Mary Ainsworth as well as from the standpoint of their successors (Everett Waters and Malcolm West. Compacted ness of the theory, possibilities for operationalization of its key concepts and its application to empirical studies of complex psychological issues that have never been scientifically explored, makes it a very prospective theory in view of possible integration of existing research findings and initiating new research and new practices in psychotherapy, social work and work in schools. The goal of this integral presentation of attachment theory is to highlight its benefits and possibilities for understanding and research complex field of human's psychosocial functioning.

    2011-01-01

    Summary Repeated interactions between infant and caregiver result in either secure or insecure relationship attachment patterns, and insecure attachment may affect individual emotion-regulation and health. Given that oxytocin enhances social approach behavior in animals and humans, we hypothesized that oxytocin might also promote the experience of attachment security in humans. Within a 3-week interval 26 healthy male students classified with an insecure attachment pattern were invited twice to an experimental session. Within each session, a single dose of oxytocin or placebo was administered, using a double-blind, placebo-controlled within-subject design. In both conditions, subjects completed an attachment task based on the Adult Attachment Projective Picture System (AAP). Thirty-two AAP picture system presentations depicted attachment-related events (e.g. illness, solitude, separation, loss), and were each accompanied by four prototypical phrases representing one secure and three insecure attachment categories. In the oxytocin condition, a significant proportion of these insecure subjects (N = 18; 69%) changed their rankings of “secure attachment” phrases towards the more appropriate for the AAP picture presentation, and the same subjects decreased in overall rating of the “insecure attachment” phrases. In particular, there was a significant decrease in the number of subjects ranking the pictures with “insecure-preoccupied” phrases from the placebo to the oxytocin condition. We find that a single dose of intranasally administered oxytocin is sufficient to induce a significant increase in the experience of attachment security in adults classified previously as insecure.

    Sine-bar attachment for collets, spindles, and chucks helps machinists set up quickly for precise angular cuts that require greater precision than provided by graduations of machine tools. Machinist uses attachment to index head, carriage of milling machine or lathe relative to table or turning axis of tool. Attachment accurate to 1 minute or arc depending on length of sine bar and precision of gauge blocks in setup. Attachment installs quickly and easily on almost any type of lathe or mill. Requires no special clamps or fixtures, and eliminates many trial-and-error measurements. More stable than improvised setups and not jarred out of position readily.

    Many attachment systems of the bar or stud type increase the stability of an overdenture. When selecting an attachment it is essential to consider the skill of the dentist-laboratory team as well as the dexterity of the patient and to use the easiest system that will still improve stabilization. Generally simplicity in design, ease of maintenance, and minimum leverage should be paramount considerations in selection. Use of a guide such as the EM Gauge and of the EM Attachment Selector significantly reduces the confusion in selecting attachments and increases the working armamentarium for stabilizing an overdenture.

By using locators as attachments, we can meet functional, economic and social expectation of patients with ease and satisfaction.

    Full Text Available Advances in spectral deconvolution technologies are rapidly enabling researchers to replace or enhance traditional epifluorescence microscopes with instruments capable of detecting numerous markers simultaneously in a multiplexed fashion. While significantly expediting sample throughput and elucidating sample information, this technology is limited by the spectral width of common fluorescence reporters. Semiconductor nanocrystals (NC’s are very bright, narrow band fluorescence emitters with great potential for multiplexed fluorescence detection, however the availability of NC’s with facile attachment chemistries to targeting molecules has been a severe limitation to the advancement of NC technology in applications such as immunocytochemistry and immunohistochemistry. Here we report the development of simple, yet novel attachment chemistries for antibodies onto NC’s and demonstrate how spectral deconvolution technology enables the multiplexed detection of 5 distinct NC-antibody conjugates with fluorescence emission wavelengths separated by as little as 20 nm.

    Within the research area on the determinants of childhood obesity, a relatively new approach is the use of attachment theory to explore the mechanisms underlying children's obesity risk, especially considered as emotion regulation strategies in parent-child relationship. Few are the empirical researches that have addressed this issue. The empirical investigations have used self-report measures to assess adult attachment. In attachment studies, the use of interview methods and/or performance-based instruments is advised to evaluate the entire range of possible adult attachment patterns and comprehensively explain the emotional strategies, correlates, and consequences of individual differences in attachment system functioning. The aim of this study was to explore the extent to which both parents' attachment patterns serve as self-regulative mechanisms related to childhood overweight/obesity by the Adult Attachment Projective Picture System (AAP) in a sample of 44 mothers and fathers of children referred for obesity. Insecure attachment was found as a risk factor both for mothers and fathers. Also unresolved/disorganization was found to play a significant role in childhood obesity. The role of father's attachment was explored and findings suggested considering it in etiology and treatment of childhood obesity.

    Based on the predictions of the attachment theory and the Common Sense Model of illness perceptions, the current study focused on the role played by illness perceptions in explaining the path linking attachment orientations to negative affect during recovery from cardiac illness. We predicted two putative mechanisms: (1) illness perceptions would mediate the direct association between attachment-related insecurity (especially attachment anxiety) and levels of distress at follow-up and (2) illness perceptions would interact with attachment orientations (attachment avoidance in particular) in explaining patients' distress. The sample consisted of 111 male patients admitted to the Cardiac Care Unit of the Meir Medical Center, located in the central region of Israel. Patients completed a measure of attachment orientations during hospitalization (baseline). One month later, patients' illness perceptions were measured. Patients' depression and anxiety symptoms were measured at baseline and at the six-month follow-up. The associations between attachment-related anxiety and anxiety symptoms at follow-up were fully mediated by illness perceptions. Attachment-related avoidance was found to interact with illness perceptions in the prediction of depressive symptoms at follow-up. The findings shed light on the possible dynamics among personality, cognitive appraisals, and affect regulation efforts when coping with illness.

  20. The relationship of adult attachment to emotion, catastrophizing, control, threshold and tolerance, in experimentally-induced pain.

    Although insecure attachment has been associated with a range of variables linked with problematic adjustment to chronic pain, the causal direction of these relationships remains unclear. Adult attachment style is, theoretically, developmentally antecedent to cognitions, emotions and behaviours (and might therefore be expected to contribute to maladjustment). It can also be argued, however, that the experience of chronic pain increases attachment insecurity. This project examined this issue by determining associations between adult attachment characteristics, collected prior to an acute (coldpressor) pain experience, and a range of emotional, cognitive, pain tolerance, intensity and threshold variables collected during and after the coldpressor task. A convenience sample of 58 participants with no history of chronic pain was recruited. Results demonstrated that attachment anxiety was associated with lower pain thresholds; more stress, depression, and catastrophizing; diminished perceptions of control over pain; and diminished ability to decrease pain. Conversely, secure attachment was linked with lower levels of depression and catastrophizing, and more control over pain. Of particular interest were findings that attachment style moderated the effects of pain intensity on the tendency to catastrophize, such that insecurely attached individuals were more likely to catastrophize when reporting high pain intensity. This is the first study to link attachment with perceptions of pain in a pain-free sample. These findings cast anxious attachment as a vulnerability factor for chronic pain following acute episodes of pain, while secure attachment may provide more resilience. PMID:16359795

  2. Biliprotein maturation: the chromophore attachment.

    Science.gov (United States)

    Scheer, H; Zhao, K-H

    2008-04-01

    Biliproteins are a widespread group of brilliantly coloured photoreceptors characterized by linear tetrapyrrolic chromophores, bilins, which are covalently bound to the apoproteins via relatively stable thioether bonds. Covalent binding stabilizes the chromoproteins and is mandatory for phycobilisome assembly; and, it is also important in biliprotein applications such as fluorescence labelling. Covalent binding has, on the other hand, also considerably hindered biliprotein research because autocatalytic chromophore additions are rare, and information on enzymatic addition by lyases was limited to a single example, an EF-type lyase attaching phycocyanobilin to cysteine-alpha84 of C-phycocyanin. The discovery of new activities for the latter lyases, and of new types of lyases, have reinvigorated research activities in the subject. So far, work has mainly concentrated on cyanobacterial phycobiliproteins. Methodological advances in the process, however, as well as the finding of often large numbers of homologues, opens new possibilities for research on the subsequent assembly/disassembly of the phycobilisome in cyanobacteria and red algae, on the assembly and organization of the cryptophyte light-harvesting system, on applications in basic research such as protein folding, and on the use of phycobiliproteins for labelling.

  3. Coexistence in preferential attachment networks

    Antunović, Tonći; Racz, Miklos Z

    2013-01-01

    Competition in markets is ubiquitous: cell-phone providers, computer manufacturers, and sport gear brands all vie for customers. Though several coexisting competitors are often observed in empirical data, many current theoretical models of competition on small-world networks predict a single winner taking over the majority of the network. We introduce a new model of product adoption that focuses on word-of-mouth recommendations to provide an explanation for this coexistence of competitors. The key property of our model is that customer choices evolve simultaneously with the network of customers. When a new node joins the network, it chooses neighbors according to preferential attachment, and then chooses its type based on the number of initial neighbors of each type. This can model a new cell-phone user choosing a cell-phone provider, a new student choosing a laptop, or a new athletic team member choosing a gear provider. We provide a detailed analysis of the new model; in particular, we determine the possibl...

  4. Hamiltonian dynamics of preferential attachment

    International Nuclear Information System (INIS)

    Prediction and control of network dynamics are grand-challenge problems in network science. The lack of understanding of fundamental laws driving the dynamics of networks is among the reasons why many practical problems of great significance remain unsolved for decades. Here we study the dynamics of networks evolving according to preferential attachment (PA), known to approximate well the large-scale growth dynamics of a variety of real networks. We show that this dynamics is Hamiltonian, thus casting the study of complex networks dynamics to the powerful canonical formalism, in which the time evolution of a dynamical system is described by Hamilton’s equations. We derive the explicit form of the Hamiltonian that governs network growth in PA. This Hamiltonian turns out to be nearly identical to graph energy in the configuration model, which shows that the ensemble of random graphs generated by PA is nearly identical to the ensemble of random graphs with scale-free degree distributions. In other words, PA generates nothing but random graphs with power-law degree distribution. The extension of the developed canonical formalism for network analysis to richer geometric network models with non-degenerate groups of symmetries may eventually lead to a system of equations describing network dynamics at small scales.

    2012-11-01

    Full Text Available A new scale measuring patient-therapist attachment avoidance was developed. Attachment Avoidance in Therapy Scale is a new measure based on the Bartholomew model of adult attachment (Bartholomew & Horowitz, 1991 and the Experience in Close Relationships Scale (Brennan, Clark, & Shaver, 1998 to measure patients’ attachment avoidance towards therapists. With 112 patient-therapist dyads participating in the study, validation of a preliminary scale – measuring both attachment anxiety and attachment avoidance in therapy – took place using therapists’ evaluations of patients’ relational behavior and patients’ self-reports about their attitude toward psychotherapy. Analysis of the data revealed six underlying scales. Results showed all six scales to be reliable. Validation of scales measuring attachment anxiety failed. The importance of Attachment Avoidance in Therapy Scale and its subscales is discussed.

    2015-01-01

    We study the transient (i.e. emerging or disappearing) C IV broad absorption line (BAL) components in 50 radio detected QSOs using multi-epoch spectra available in Sloan Digital Sky Survey DR10. We report the detectionof 6 BALQSOs having at least one distinct transient C IV absorption component. Based on the structure function analysis of optical light curves, we suggest that the transient absorption is unlikely to be triggered by continuum variations. Transient absorption components usually have low C IV equivalent widths ( 10000 \\kms) and typically occur over rest-frame timescales > 800 days. The detection rate of transient C IV absorption seen in our sample is higher than that reported in the literature. Using a control sample of QSOs, we show that this difference is most likely due to the longer monitoring time-scale of sources in our sample while the effect of small number statistics cannot be ignored. Thus, in order to establish the role played by radio jets in driving the BAL outflows, we need a larger...

  3. Attachment and children's biased attentional processing: evidence for the exclusion of attachment-related information.

    Directory of Open Access Journals (Sweden)

    Eva Vandevivere

    Full Text Available Research in both infants and adults demonstrated that attachment expectations are associated with the attentional processing of attachment-related information. However, this research suffered from methodological issues and has not been validated across ages. Employing a more ecologically valid paradigm to measure attentional processes by virtue of eye tracking, the current study tested the defensive exclusion hypothesis in late childhood. According to this hypothesis, insecurely attached children are assumed to defensively exclude attachment-related information. We hypothesized that securely attached children process attachment- related neutral and emotional information in a more open manner compared to insecurely attached children. Sixty-two children (59.7% girls, 8-12 years completed two different tasks, while eye movements were recorded: task one presented an array of neutral faces including mother and unfamiliar women and task two presented the same with happy and angry faces. Results indicated that more securely attached children looked longer at mother's face regardless of the emotional expression. Also, they tend to have more maintained attention to mother's neutral face. Furthermore, more attachment avoidance was related to a reduced total viewing time of mother's neutral, happy, and angry face. Attachment anxiety was not consistently related to the processing of mother's face. Findings support the theoretical assumption that securely attached children have an open manner of processing all attachment-related information.

    We are interested in testing the antimicrobial activity of a porphyrin that is attached to a polymer. The porphyrin (5-(4-carboxyphenyl)-10,15,20-tris-(4-pryridyl)) was synthesized from methyl 4-formyl benzoate, 4-pyridinecarboxaldehyde, and pyrrole and attached to a copolymer of polystyrene/poly(vinyl benzyl chloride), which was synthesized by free radical polymerization. The antimicrobial activity of the polymer-attached porphyrin was then determined for gram-negative E. Coli grown to 0.80 OD. In this procedure, glass slides were coated with polymer-attached porphyrin via dip-coating, and the E. Coli bacteria were plated in Luria Broth media. The plates were subsequently exposed to light overnight before they were incubated as porphyrins act as photo-sensitizers when irradiated with light. The polymer-attached porphyrin did exhibit antimicrobial activity and parameters that affect its efficiency will be discussed.

  5. Job Cognition and Justice Influencing Organizational Attachment

    2014-02-01

    Full Text Available Organizational attachment echoes the psychological bond between employee and employer relations, differing from affective component of commitment in terms of employees’ psychological and behavioral involvement. This study examines the extent to which employee perception about procedural, distributive justice and job cognition contributes toward organizational attachment in India. The effect of justice and job cognition variables relates differently to previous studies from western part of the globe. First, in past studies, procedural justice predicted commitment, whereas, for Indian employees, distributive justice contributed to organizational attachment. Second, the contribution of extrinsic job cognition in organizational attachment was evident in the model developed using Structural Equation Modeling (SEM; AMOS. Organizations must take cognizance of the outcomes exhibited by the behavior of managers while following the laid down policies and processes. Cognition of fairness at workplace and attachment can play key role in limiting retention. Practical implications and future research directions are discussed.

  6. Attachment to groups: theory and measurement.

    Smith, E R; Murphy, J; Coats, S

    1999-07-01

    Aspects of people's identification with groups may be understood by borrowing theoretical ideas and measurement strategies from research on attachment in close relationships. People have mental models of the self as a group member and of groups as sources of identity and esteem. These models affect thoughts, emotions, and behaviors related to group membership. Three studies show that two dimensions of attachment to groups, attachment anxiety and avoidance, can be assessed with good reliability, validity, and over-time stability. These factors are distinct from relationship attachment and from other measures of group identification. Group attachment predicts several important outcomes, including emotions concerning the group, time and activities shared with a group, social support, collective self-esteem, and ways of resolving conflict. This conceptualization provides new insights into the nature of people's psychological ties to groups.

    Attachment theory proposes that the quality of the mother-child tie predicts the quality of a child's other close relationships. The purpose of this study was to test whether security of attachment to mother is related to the quality of a preschooler's best friendships. 33 4-year-old and their best friends participated (mean age = 46 months). Attachment Q-set data were collected to score security of mother-child attachment. Security data were used to classify the friend pairs as secure-secure or secure-insecure. Best friend dyads were observed for a 1-hour free-play session. Each pair's behavior was described with the Dyadic Relationships Q-set, a measure designed to describe the behavior of a pair of children. Secure-secure pairs were more harmonious, less controlling, more responsive, and happier than secure-insecure pairs. The results are related to previous work on attachment and social competence.

    Apart from the paradigm that cell-biomaterials interaction depends on the adsorption of soluble adhesive proteins we anticipate that upon distinct conditions also other, less soluble ECM proteins such as collagens, associate with the biomaterials interface with consequences for cellular response that might be of significant bioengineering interest. Using atomic force microscopy (AFM) we seek to follow the nanoscale behavior of adsorbed type IV collagen (Col IV)--a unique multifunctional matrix protein involved in the organization of basement membranes (BMs) including vascular ones. We have previously shown that substratum wettability significantly affects Col IV adsorption pattern, and in turn alters endothelial cells interaction. Here we introduce two new model surfaces based on self-assembled monolayers (SAMs), a positively charged -NH(2) , and negatively charged -COOH surface, to learn more about their particular effect on Col IV behavior. AFM studies revealed distinct pattern of Col IV assembly onto the two SAMs resembling different aspects of network-like structure or aggregates (suggesting altered protein conformation). Moreover, the amount of adsorbed FITC-labeled Col IV was quantified and showed about twice more protein on NH(2) substrata. Human umbilical vein endothelial cells attached less efficiently to Col IV adsorbed on negatively charged COOH surface judged by altered cell spreading, focal adhesions formation, and actin cytoskeleton development. Immunofluorescence studies also revealed better Col IV recognition by both α(1) and α(2) integrins on positively charged NH(2) substrata resulting in higher phosphorylated focal adhesion kinase recruitment in the focal adhesion complexes. On COOH surface, no integrin clustering was observed. Taken altogether these results, point to the possibility that combined NH(2) and Col IV functionalization may support endothelization of cardiovascular implants.

    100 economically disadvantaged mothers and their infants were observed in the Ainsworth and Wittig "strange situation" at 12 and 18 months. Infants were classified as secure, anxiously attached/avoidant, or anxiously attached/resistant. In addition, mothers reported occurrence of stressful events related to the stability of the caretaking environment during the 12--18 month period by completing a 44-item checklist concerning work, finances, family, neighbors, health, etc. 62 infants were assigned to the same attachment classification at both 12 and 18 months (p less than .01). Despite this stability, significantly more infants changes classification than in a recent study of stable middle-class families. With the present sample, anxious attachment was associated with less stable caretaking environments than secure attachment; change from secure to anxious attachment was associated with higher stressful-event scores than stable secure attachment.

    Full Text Available 【Abstract】 Objective: Fractures of the capitellum and trochlea constitute less than 1% of all elbow fractures and a shear fracture involving the capitellum and extending medially into most of the trochlea is rarely reported. Type IV capitellum fracture is still controversial in regard to its ra-diographic appearance, surgical approach and osteosynthesis. We report 10 cases of type IV capitellum fracture with a view to elucidating its clinical features and treatment outcome. Methods: We treated 10 patients of type IV capitellum fracture with a mean age of 32 years. A uniform surgical approach and postoperative rehabilitation were followed. Results: Nine patients presented to us after a mean of 4 days of injury and one patient was nonunion after 6 months of injury who had been treated conservatively by a bone setter.

    Full Text Available Studies regarding the relationship between attachment and psychopathology during adolescence have been performed separately for clinical and nonclinical adolescents and have used different assessment measures, which together might produce a methodological bias that increases the association between attachment and psychopathology. With the aim of avoiding this bias, the present study used identical measures to explore the relationship between attachment styles and internalizing or externalizing symptoms in clinical and nonclinical samples of adolescents. The sample consisted of 258 adolescents, 129 clinical and 129 nonclinical, aged between 14 and 18 years. The adolescents in each sample were matched for age, gender, and socioeconomic status. Attachment was assessed using the CaMir Q-sort, and psychopathological symptoms were assessed by means of the Youth Self Report (YSR. The relationships between attachment and psychopathology were similar for clinical and nonclinical adolescents. A preoccupied attachment style predicted internalizing and externalizing symptoms, somatic complaints, anxious-fearful behavior, verbal aggression, attention-seeking behavior, and thinking problems. Compared to previous studies, this research has made it possible to identify broader, stronger, and more specific associations between preoccupied attachment style and psychopathological symptoms in adolescents.

    Ni-Ti alloy due to its unique mechanical properties, is used for many types of implants. Failure of these implants can be attributed to many different factors; however infections are a common problem. In this paper, the attachment of the bacteria, Staphylococcus aureus, to the Ni-Ti surface modified by a range of processes with and without of light activation (used to elicit antimicrobial properties of materials) was assessed and related to different surface characteristics. Before the light activation the number of bacterial colony forming units was the greatest for the samples thermally oxidised at 600 deg. C. This sample and the spark oxidised samples showed the highest photocatalytic activity but only the thermally oxidised samples at 600 deg. C showed a significant drop of S. aureus attachment. The findings in this study indicate that light activation and treating samples at 600 deg. C is a promising method for Ni-Ti implant applications with inherent antimicrobial properties. Light activation was shown to be an effective way to trigger photocatalytic reactions on samples covered with relatively thick titanium dioxide via accumulation of photons in the surface and a possible increase in defects which may result in free oxygen. Moreover, light activation caused an increase in the total surface energy.

    Youth's low level of civic and political engagement may detrimentally affect the health of communities and the democratic system. This paper examines the role of community attachment in explaining youth's levels of civic and engagement. This examination requires an evaluation of existing measures of community attachment and their relevance for understanding youth's experiences. The paper uses a student sample, highlighting a group of youth who have a degree of variation in their experiences of community attachment. We find that subjective measures of community attachment are related to volunteering and voting, but the objective measure of community attachment, that is, years of residence, affects voting and not volunteering. Different mechanisms explain civic engagement versus political engagement. As such, different strategies are required to combat low levels of civic versus political engagement.

    Children from mothers with HIV-related psychosis are frequently raised in challenging contexts, yet the extent to which these children grow up in insecure or disordered attachment relationships is unknown. Using the Strange Situation Procedure the distribution of attachment relationships of children from mothers with HIV and psychosis (n = 45) was compared with children from mothers with HIV without psychosis (n = 41). No significant differences in the distributions were found between the two groups and attachment was not associated with specific psychotic symptomatology. Security of attachment was associated with more people providing the mother with emotional support, but only in the psychosis group. Disordered attachment (24%) was more often found in the total sample than in studies with other normal and high risk populations. Recommendations were made for future research about factors facilitating resilience in the children and on interventions increasing emotional support for affected mothers.

  20. Attachment and parental divorce: a test of the diffusion and sensitive period hypotheses.

    Fraley, R Chris; Heffernan, Marie E

    2013-09-01

    One of the assumptions of attachment theory is that disruptions in parental relationships are prospectively related to insecure attachment patterns in adulthood. The majority of research that has evaluated this hypothesis, however, has been based on retrospective reports of the quality of relationships with parents-research that is subject to retrospective biases. In the present research, the authors examined the impact of parental divorce-an event that can be assessed relatively objectively-on attachment patterns in adulthood across two samples. The data indicate that parental divorce has selective rather than diffuse implications for insecure attachment. Namely, parental divorce was more strongly related to insecure relationships with parents in adulthood than insecure relationships with romantic partners or friends. In addition, parental insecurity was most pronounced when parental divorce took place in early childhood. This finding is consistent with hypotheses about sensitive periods in attachment development.

    Full Text Available Integrating theories of adult attachment and well-being at the workplace, the present study tested the role of attachment style in predicting work-related well-being in terms of job satisfaction and job involvement, over and above dispositional trait measures (emotional traits and work-related traits. A sample of workers took part in a correlational study that explored the relationships among a adult attachment, b emotional traits, c work-related traits, and d work-related well-being indices. The results showed that both secure and anxious attachment style explained workers’ job involvement, whereas the secure and avoidant attachment styles explained workers’ job satisfaction. The current findings thus confirm and expand the literature's emphasis on studying the variables and processes that underlie people's mental health in the work setting, and have implications for assessing and promoting well-being in the workplace.

    Measuring attachment behaviors is relevant to creating secure couple relationships. This article seeks to test and examine the reliability and validity of the Brief Accessibility, Responsiveness, and Engagement (BARE) Scale-a practical measure of couple attachment-in a clinical sample. Couples took the BARE and other assessments measuring relationship functioning (self and partner reports of relationship satisfaction, relationship stability, positive and negative communication, and attachment styles). Results suggest that the BARE appears to be a reliable and valid tool for assessing couple attachment and can accurately predict and classify whether the couples belong in the clinical or nonclinical group, as well as their level of relationship satisfaction. Results also indicate attachment behaviors are related to relationship outcomes. PMID:26748730

    Attachment avoidance and anxiety are associated with negative emotions. However, the mechanisms underlying these associations are not fully understood. We investigated environmental mastery and positive relations with others as two mechanisms behind the attachment-emotion link in a sample of 343 adults. As predicted, attachment avoidance and anxiety were related to greater fear, hostility, envy and depression through lower mastery. Contrary to our hypothesis, positive relations mediated only the attachment-depression link. In addition, by adopting a moderated mediation approach, we were able to show that mastery mattered most for individuals high on avoidance: The indirect effect of avoidance through lack of mastery on fear, hostility and depression (but not on envy) increased with higher avoidance scores. Contrary to our predictions, poor relationships did not matter more as sources of negative emotions as anxiety increased. These findings underscore that the emotional life of avoidantly attached individuals is especially jeopardised by poor mastery. PMID:26079543

    This study examined whether infant attachment security moderates the association between parenting in preschool and later aggressive behavior among a sample of children at high risk for developing conduct problems. Participants were 82 adolescent mother-child dyads recruited from the community. Infant attachment status at age 1 year was measured using the Strange Situation. When children were aged 4.5 years, mothers reported on their self-efficacy in regards to parenting, and mothers' positive parenting and criticism were coded from direct observations of parent-child interactions. In grade 1, mothers reported on their children's aggressive behavior. Infant secure attachment significantly moderated the association between observed maternal criticism and child aggression. That is, among insecurely attached children, higher levels of maternal criticism were associated with more severe aggression. This longitudinal finding suggests that a secure attachment may buffer the deleterious effects of harsh parenting on child aggression.

    Adult attachment research does not systematically distinguish between experiential and expressive forms of regulation. Drawing insights from developmental-functionalism - a lifespan theory of emotion and emotion regulation - the current report examined the relations among attachment, trait emotion, and expressive emotion regulation in a large (N = 1204) sample of older women. Although both preoccupation and fearful-avoidance predicted more anxiety and anger, preoccupation predicted greater fear withdrawal and less fear expression, while fearful-avoidance predicted greater fear expression and greater anger withdrawal; attachment security predicted less fear withdrawal and less anger expression. Importantly, results regarding expressive regulation held even when controlling for trait levels of the underlying emotion. Results are interpreted within the context of models of attachment and lifespan socioemotional functioning. It is suggested that attachment research may benefit from considering the distinct functions of experienced versus expressed emotion in developmentally diverse contexts. Limitations are discussed and directions for future research are given.

    PURPOSE The aim of the present study was to evaluate, by means of strain gauge analysis, the effect of different implant angulations on strains around two implants retaining mandibular overdenture with Locator attachments. MATERIALS AND METHODS Four duplicate mandibular acrylic models were constructed. Two implants were inserted in the canine regions using the following degrees of distal inclinations: group I (control); 0°, group II; 10°, group III; 20°, and group IV; 30°. Locator pink attachments were used to connect the overdenture to the implants and Locator red (designed for severely angled implants) was used for group IV (group IVred). For each group, two linear strain gauges were attached at the mesial and distal surfaces of the acrylic resin around each implant. Peri-implant strain was measured on loading and non-loading sides during bilateral and unilateral loading. RESULTS For all groups, the mesial surfaces of the implants at loading and non-loading sides experienced compressive (negative) strains, while the distal implant surfaces showed tensile (positive) strains. Group IV showed the highest strain, followed by group III, group II. Both group I and group IVred showed the lowest strain. The strain gauges at the mesial surface of the loading side recorded the highest strain, and the distal surface at non-loading side showed the lowest strain. Unilateral loading recorded significantly higher strain than bilateral loading. CONCLUSION Peri-implant strains around two implants used to retain mandibular overdentures with Locator attachments increase as distal implant inclination increases, except when red nylon inserts were used.

    Full Text Available Considering the structural role of type IV collagen (Col IV in the assembly of the basement membrane (BM and the perspective of mimicking its organization for vascular tissue engineering purposes, we studied the adsorption pattern of this protein on model hydrophilic (clean glass and hydrophobic trichloro(octadecylsilane (ODS surfaces known to strongly affect the behavior of other matrix proteins. The amount of fluorescently labeled Col IV was quantified showing saturation of the surface for concentration of the adsorbing solution of about 50μg/ml, but with approximately twice more adsorbed protein on ODS. AFM studies revealed a fine – nearly single molecular size – network arrangement of Col IV on hydrophilic glass, which turns into a prominent and growing polygonal network consisting of molecular aggregates on hydrophobic ODS. The protein layer forms within minutes in a concentration-dependent manner. We further found that human umbilical vein endothelial cells (HUVEC attach less efficiently to the aggregated Col IV (on ODS, as judged by the significantly altered cell spreading, focal adhesions formation and the development of actin cytoskeleton. Conversely, the immunofluorescence studies for integrins revealed that the fine Col IV network formed on hydrophilic substrata is better recognized by the cells via both α1 and α2 heterodimers which support cellular interaction, apart from these on hydrophobic ODS where almost no clustering of integrins was observed.

    Attachment security towards parents and peers in adolescence, and romantic attachment styles and emotion regulation strategies in young adulthood, were evaluated using an eight-year longitudinal design. Fifty-six young adults completed the Inventory of Parent and Peer Attachment (IPPA) at age 14, and then, at age 22, the Experience in Close Relationships (ECR) and the Coping Inventory for Stressful Situations (CISS), an emotion regulation questionnaire concerning coping strategies, including task-oriented versus emotion-oriented foci. Results indicated that greater insecurity to parents and peers in adolescence predicted a more anxious romantic attachment style and greater use of emotion-oriented strategies in adulthood. Concurrently, anxious adult attachment style was related to more emotion-oriented strategies, whereas an avoidant attachment style was related to less support-seeking. Analyses also identified emotion-oriented coping strategies as a partial mediator of the link between adolescent attachment insecurity to parents and adult anxious attachment, and a complete mediator of the association between adolescent attachment insecurity to peers and adult anxious attachment. These findings support the core assumption of continuity in attachment theory, where relationships to parents influence close romantic relationships in adulthood.

    2016-06-01

    Since the beginning of clinical attachment research in the mid-1980s the number of research projects in this area has been continuously increasing. The research questions so far can be allocated to numerous medical disciplines such as psychosomatic medicine, adult psychiatry or child and adolescent psychiatry. Recently, children with ADHD and their families have also become subjects of this branch of research. Their specific behavioral characteristics from early childhood on constitute unique challenges on the parent-child interaction. If these interactions develop in a suboptimal way, children may develop an insecure or even a disorganized attachment quality. The latter represents a risk factor for a clinically significant psychopathological development.This article initially presents basic principles of attachment theory and discusses the relevance of the cardinal symptoms of ADHD for clinical attachment research. Subsequently, it outlines and discusses the main results of existing research regarding attachment and ADHD. It concludes with a perspective on research questions that need to be addressed in the future with regard to a transgenerational model that highlights the importance of parental attachment representations to the development of children's attachment quality.

    2009-01-01

    Attachment theory predicts and subsequent empirical research has amply demonstrated that individual variations in patterns of early attachment behaviour are primarily influenced by differences in sensitive responsiveness of caregivers. However, meta-analyses have shown that parenting behaviour accounts for about one third of the variance in attachment security or disorganisation. The exclusively environmental explanation has been challenged by results demonstrating some, albeit inconclusive, evidence of the effect of infant temperament. In this paper, after reviewing briefly the well-demonstrated familial and wider environmental influences, the evidence is reviewed for genetic and gene-environment interaction effects on developing early attachment relationships. Studies investigating the interaction of genes of monoamine neurotransmission with parenting environment in the course of early relationship development suggest that children's differential susceptibility to the rearing environment depends partly on genetic differences. In addition to the overview of environmental and genetic contributions to infant attachment, and especially to disorganised attachment relevant to mental health issues, the few existing studies of gene-attachment interaction effects on development of childhood behavioural problems are also reviewed. A short account of the most important methodological problems to be overcome in molecular genetic studies of psychological and psychiatric phenotypes is also given. Finally, animal research focusing on brain-structural aspects related to early care and the new, conceptually important direction of studying environmental programming of early development through epigenetic modification of gene functioning is examined in brief.

  15. Effect of method of crystallization on the IV-III and IV-II polymorphic transitions of ammonium nitrate

    International Nuclear Information System (INIS)

    A study has been undertaken on the effect of crystallization method on the IV ↔ III transition of ammonium nitrate (AN). AN is crystallized in three different ways, viz. recrystallization, evaporative crystallization and melt crystallization. When the samples were crystallized from saturated aqueous solution, ideal crystals were formed, which behaved differently from the crystals formed from the other methods. The DTA examination of the crystals showed that the crystals have different transition behaviour. The moisture uptake of the samples determined were found to have influenced by the mode of crystallization. The samples were further analyzed by powder X-ray diffraction (XRD) and scanning electron microscopy (SEM). The present study showed that the parameters like thermal history, number of previous transformations and moisture content have a very negligible influence on the IV ↔ III transition of AN as compared to the method of crystallization

In addition, attachment styles have been proposed to meditate the association between stressful life events and subsequent psychiatric status. The current study aimed to empirically test the attachment typology proposed by Collins and Read (1990. Specifically, LPA was used to determine if the proposed four styles can be derived from scores on the dimensions of closeness/dependency and anxiety. In addition, we aimed to test if the resultant attachment styles predicted the severity of psychopathology in response to a whiplash trauma. A large sample of Danish trauma victims (N=1577 participated. A Latent Profile Analysis was conducted, using Mplus 5.1, on scores from the RAAS scale to ascertain if there were underlying homogeneous attachment classes/subgroups. Class membership was used in a series of one-way ANOVA tests to determine if classes were significantly different in terms of mean scores on measures of psychopathology. The three class solution was considered optimal. Class one was termed Fearful (18.6%, Class two Preoccupied (34.5%, and Class three Secure (46.9%. The secure class evidenced significantly lower mean scores on PTSD, depression, and anxiety measures compared to other classes, whereas the fearful class evidenced significantly higher mean scores compared to other classes. The results demonstrated evidence of three discrete classes of attachment styles, which were labelled secure, preoccupied, and fearful. This is in contrast to previous cluster analytic techniques which have identified four and two attachment styles based on the RAAS.In addition, Securely attached individuals display lower levels of psychopathology post

    A polymer-cisplatin(IV) conjugate was prepared by attaching Pt(IV)-COOH to a biodegradable amphiphilic block copolymer containing pendant OH groups. The conjugate can assemble into micelles (M(Pt)) with a mean diameter of ca. 169nm. Further, curcumin (CM) was used to sensitize platinum drug based nanoparticles to overcome cisplatin resistance and enhance antitumor efficacy. In vitro studies showed that M(Pt)/CM combinations had great synergistic effect both on cisplatin sensitive and cisplatin resistant cell lines (A2780 and A2780DDP). In vivo studies showed that M(Pt)/CM had a much lower systemic toxicity and an enhanced antitumor efficacy compared to cisplatin alone or the corresponding cisplatin/CM combinations. Therefore, polymer-cisplatin(IV) conjugate with small molecules that serve as a non-cytotoxic or minimally cytotoxic sensitizer or enhancer provide a promising strategy, which may have potential clinical implications in the near future.

    Developmental theories highlight the salience of attachment theory in explaining vulnerability towards psychosis. At the same time there is increasing recognition that psychosis is associated with childhood trauma variables. This study explored the interaction between attachment and several trauma variables in relation to schizotypy levels in a non-clinical sample. 283 non-clinical participants completed online measures of schizotypy, attachment, childhood abuse and neglect. When five types of abuse/neglect were entered into a linear regression analysis emotional abuse was the sole independent predictor of schizotypy. Age, attachment anxiety and avoidance were independent predictors after the effects of emotional abuse were controlled for. The overall model was significant, explaining 34% of the variation in schizotypy. Moderation analysis indicated that the effect of emotional abuse was not conditional upon attachment. Parallel mediation analysis indicated small but significant indirect effects of emotional abuse on schizotypy through attachment avoidance (13%) and attachment anxiety (8%). We conclude that emotional abuse contributes to vulnerability towards psychosis both directly and indirectly through attachment insecurity. PMID:26474661

    Differences in attachment style have been linked to both emotion regulation and psychological functioning, but the emotion regulatory mechanism through which attachment style might impact symptoms of depression and anxiety is unclear. The present study examined the explanatory role of emotion dysregulation in the relation between adult attachment style and symptoms of depression and generalized anxiety disorder (GAD) in a sample of 284 adults. Secure attachment was associated with lower depression and GAD symptoms and lower emotion dysregulation, whereas insecure attachment styles were generally associated with higher depression and GAD scores and higher emotion dysregulation. Perceived inability to generate effective emotion regulation strategies mediated the relation between insecure attachment and both depression and GAD symptoms. Nonacceptance of negative emotions and inability to control impulsive behaviors emerged as additional mediators of the relation between insecure attachment styles and GAD symptoms. The differential contribution of attachment style and emotion regulation to the prediction of depression and GAD symptoms may reflect differences in vulnerability to depression and GAD.

    The present study investigated whether oculomotor behavior is influenced by attachment styles. The Relationship Scales Questionnaire was used to assess attachment styles of forty-eight voluntary university students and to classify them into attachment groups (secure, preoccupied, fearful, and dismissing). Eye-tracking was recorded while participants engaged in a 3-seconds free visual exploration of stimuli presenting either a positive or a negative picture together with a neutral picture, all depicting social interactions. The task consisted in identifying whether the two pictures depicted the same emotion. Results showed that the processing of negative pictures was impermeable to attachment style, while the processing of positive pictures was significantly influenced by individual differences in insecure attachment. The groups highly avoidant regarding to attachment (dismissing and fearful) showed reduced accuracy, suggesting a higher threshold for recognizing positive emotions compared to the secure group. The groups with higher attachment anxiety (preoccupied and fearful) showed differences in automatic capture of attention, in particular an increased delay preceding the first fixation to a picture of positive emotional valence. Despite lenient statistical thresholds induced by the limited sample size of some groups (p emotions is affected by attachment styles. These results are discussed within a broader evolutionary framework. PMID:25693911

    Childhood obesity has become a rising health problem, and because parental obesity is a basic risk factor for childhood obesity, biological factors have been especially considered in the complex etiology. Aspects of the family interaction, e.g., mother-child attachment, have not been the main focus. Our study tried to fill this gap by investigating whether there is a difference between children of obese and normal weight mothers in terms of mother-child attachment, and whether mother-child attachment predicts child's weight, in a sample of 31 obese and 31 normal weight mothers with children aged 19 to 58 months. Mother-child attachment was measured with the Attachment Q-Set. We found that (1) children of obese mothers showed a lower quality of mother-child attachment than children of normal weight mothers, which indicates that they are less likely to use their mothers as a secure base; (2) the attachment quality predicted child`s BMI percentile; and (3) the mother-child attachment adds incremental validity to the prediction of child's BMI beyond biological parameters (child's BMI birth percentile, BMI of the parents) and mother's relationship status. Implications of our findings are discussed.

    Emotionally focused couple therapy (EFT; Johnson, The practice of emotionally focused couple therapy (1st/2nd edition). Brunner-Routledge, New York, 2004) is an effective treatment of relationship distress (Johnson et al., Clinical Psychology: Science and Practice, 1999; 6, 67). However, less is known about EFT's impact on couples' relationship-specific attachment bond. Using hierarchical linear modeling with a sample of 32 couples, we examined session-by-session changes in couples' relationship-specific attachment anxiety and avoidance and pre- to posttherapy changes in their relationship-specific attachment behaviors. Couples significantly decreased in relationship-specific attachment avoidance, and those who completed a blamer softening significantly decreased in relationship-specific attachment anxiety. Couples' attachment behavior significantly increased toward security. Finally, session-by-session decreases in relationship-specific attachment anxiety and avoidance were significant associated with increases in relationship satisfaction across sessions. These results provide empirical support for the attachment-based assumptions of EFT. Video abstract accessible by clicking here. PMID:26511674

    Every few years the International Terrestrial Reference System (ITRS) Center of the International Earth Rotation and Reference Systems Service (IERS) decides to generate a new version of the International Terrestrial Reference Frame (ITRF). For the upcoming ITRF2014 the official contribution of the International VLBI Service for Geodesy and Astrometry (IVS) comprises 5796 combined sessions in SINEX file format from 1979.6 to 2015.0 containing 158 stations, overall. Nine AC contributions were included in the combination process, using five different software packages. Station coordinate time series of the combined solution show an overall repeatability of 3.3 mm for the north, 4.3 mm for the east and 7.5 mm for the height component over all stations. The minimum repeatabilities are 1.5 mm for north, 2.1 mm for east and 2.9 mm for height. One of the important differences between the IVS contribution to the ITRF2014 and the routine IVS combination is the omission of the correction for non-tidal atmospheric pressure loading (NTAL). Comparisons between the amplitudes of the annual signals derived by the VLBI observations and the annual signals from an NTAL model show that for some stations, NTAL has a high impact on station height variation. For other stations, the effect of NTAL is low. Occasionally other loading effects have a higher influence (e.g. continental water storage loading). External comparisons of the scale parameter between the VTRF2014 (a TRF based on combined VLBI solutions), DTRF2008 (DGFI-TUM realization of ITRS) and ITRF2008 revealed a significant difference in the scale. A scale difference of 0.11 ppb (i.e. 0.7 mm on the Earth's surface) has been detected between the VTRF2014 and the DTRF2008, and a scale difference of 0.44 ppb (i.e. 2.8 mm on the Earth's surface) between the VTRF2014 and ITRF2008. Internal comparisons between the EOP of the combined solution and the individual solutions from the AC contributions show a WRMS in X- and Y-Pole between

    PURPOSE The aim of this study was to evaluate the clinical findings and patient satisfaction on implant overdenture designed with Locator implant attachment or Locator bar attachment in mandibular edentulous patients. MATERIALS AND METHODS Implant survival rate, marginal bone loss, probing depth, peri-implant inflammation, bleeding, plaque, calculus, complications, and satisfaction were evaluated on sixteen patients who were treated with mandibular overdenture and have used it for at least 1 year (Locator implant attachment: n=8, Locator bar attachment: n=8). RESULTS Marginal bone loss, probing depth, plaque index of the Locator bar attachment group were significantly lower than the Locator implant attachment group (P.05). The replacement of the attachment components was the most common complication in both groups. Although there was no correlation between marginal bone loss and plaque index, a significant correlation was found between marginal bone loss and probing depth. CONCLUSION The Locator bar attachment group indicates lesser marginal bone loss and need for maintenance, as compared with the Locator implant attachment group. This may be due to the splinting effect among implants rather than the types of Locator attachment. PMID:27555901

    2013-08-01

    This research was aimed at providing first evidence concerning the relationship between adults' self-reported attachment style and their performance on a standard 'theory of mind' task. Based on adult attachment theory, we hypothesized that the two dimensions of self-reported adult attachment, anxiety and avoidance, are differently related to 'theory of mind,' and that this relationship is moderated by variables concerning the 'theory of mind' stimuli. The 'Experiences in Close Relationships' questionnaire and the 'Reading the Mind in the Eyes' test were administered to 132 young women. In line with our expectations, women's attachment-related anxiety was associated with better mind reading concerning stimuli that were emotionally neutral or difficult to recognize.

    The aim of this study was to obtain better insight into the associations between attachment styles and employees' life satisfaction. This was achieved by examining the mediating roles of burnout and job satisfaction. Three hundred and thirty-nine employees, from a convenience community sample, participated in the current study. Results of the mediation model indicated that the associations between avoidance and life satisfaction were mediated by burnout and job satisfaction. However, the associations between attachment anxiety and life satisfaction were mediated by burnout but not by job satisfaction. Theoretical and practical implications for organizations and for attachment theory at work are discussed.

    The effect of the attachment and spreading of living cells on the modes of a grating coupled reverse symmetry waveguide sensor is investigated in real time. The reverse symmetry design has an increased probing depth into the sample making it well suited for the monitoring of cell morphology....... As a result, significant changes in the incoupling peak height and peak shape were observed during cell attachment and spreading. It is suggested that the area under the incoupling peaks reflects the initial cell attachment process, while the mean peak position is mostly governed by the spreading of the cells...

    1990-10-01

    Mechanical attachments for overdentures have been available in various forms for over a century. The explosive interest in osseointegration and the effort on the part of the profession to avoid the complete denture as a treatment modality has stirred the interest in positive retentive elements for overdentures represented by the mechanical stud and bar attachments. The cited references provide a resource as a trouble-free guide in the selection and use of the various stud and bar attachment systems. The clinical examples show a pattern of application not generally discussed by the manufacturers, illustrating the simplicity of use with the options for all attachments including magnets. The discussion on magnets comes from 9 years of clinical experience. Rare earth magnets provide excellent adjunct retention, and their assembly follows the same protocol and complexity as stud attachment systems. All magnets, at the present state of the art, have a corrosion potential with the exception of the Laser Sealed Units (Golden Dental, Golden, CO). Finally, the mechanics of the attachment overdenture serves as an excellent training field for the osseointegrated prosthesis, be it the classic Brånemark (Nobelpharma USA, Chicago, IL) restorative or the implant overdenture concept.

    2007-05-01

    Full Text Available Attachment theory, as developed by Bowlby and Ainsworth, represented a major departure from the current theories of human development of the time, particularly in its rejection of the major tenets of psychoanalytic theory and its integration of core ideas from evolution theory and cybernetics (Ainsworth & Bowlby, 1991. Attachment theory posits that a foundational human instinct, the desire to achieve safety and protection through proximity to a protective figure, is responsible for the formation of a special class of life-long affectional bonds, referred to as “attachments.” Emotional security is derived to a great extent, according to the theory, from experience with caregivers who are consistently responsive to the developing infant’s expression of attachment behavior toward them. Forty years of empirical research has shown that attachment is a universal characteristic that predicts children’s development of cognitive and social competence, emotional regulation, and positive self-image (Weinfield, Sroufe, Egeland, & Carlson, 1999. Social work educators are currently challenged to better integrate the findings of attachment research into their curricula to reflect more the current state of developmental science.

    2006-11-01

    Full Text Available Abstract Background Attachment theory allows specific predictions about the role of attachment representations in organizing behavior. Insecure attachment is hypothesized to predict maladaptive emotional regulation whereas secure attachment is hypothesized to predict adaptive emotional regulation. In this paper, we test specific hypotheses about the role of attachment representations in substance abuse/dependence and treatment participation. Based on theory, we expect divergence between levels of maladaptive functioning and adaptive methods of regulating negative emotions. Methods Participants for this study consist of a sample of adoptees participating in an ongoing longitudinal adoption study (n = 208. The Semi-Structured Assessment of the Genetics of Alcohol-II 41 was used to determine lifetime substance abuse/dependence and treatment participation. Attachment representations were derived by the Adult Attachment Interview [AAI; 16]. We constructed a prior contrasts reflecting theoretical predictions for the association between attachment representations, substance abuse/dependence and treatment participation. Results Logistic regression was used to test our hypotheses. As predicted, individuals classified as dismissing, preoccupied or earned-secure reported the highest rates of substance abuse/dependence. Individuals classified as dismissing reported significantly lower rates of treatment participation despite their high rates of substance abuse/dependence. As expected, the continuous-secure group reported lowest rates of both substance abuse/dependence and treatment participation. Conclusion The findings from this study identify attachment representations as an influential factor in understanding the divergence between problematic substance use and treatment utilization. The findings further imply that treatment may need to take attachment representations into account to promote successful recovery.

    A novel optical sensor has been proposed for sensitive determination of thorium (IV) ion in aqueous solutions. The thorium sensing membrane was prepared by incorporating 4-(p-nitrophenyl azo)-pyrocatechol (NAP) as ionophore in the plasticized PVC membrane containing tributyl phosphate (TBP) as plasticizer. The membrane responds to thorium ion by changing color reversibly from yellow to red-brown in glycine buffer solution at pH 3.5. The proposed sensor displays a linear range of 8.66 x 10{sup -6}-2.00 x 10{sup -4} M with a limit of detection of 6 x 10{sup -6} M. The response time of the optode was about 8.8-12.5 min, depending on the concentration of Th (IV) ions. The selectivity of optode to Th (IV) ions in glycine buffer is good. The sensor can readily be regenerated by exposure to a solution mixture of sodium fluoride and 5-sulfosalicylic acid (dihydrate) (0.01 M each). The optode is fully reversible. The proposed optode was applied to the determination of thorium (IV) in environmental water samples.

    Full Text Available Forgiveness and empathy are factors which are influential in improving the relationships between people, themselves can be affected by various factors in turn. The purpose of this research was to investigate the relationship between the styles of attachment to God and forgiveness and empathy among female students in the city of Qom. 250 students were selected from the city of Qom by cluster sampling. Three questionnaires were used: styles of attachment to God by Kirkpatrick and Rowatt, emotional empathy by Mehrabian and Epstein and forgiveness inventory by Enzeit. Pearson correlation and Regression analysis were used for data analysis. The style of secure attachment to God had a significantly positive relationship with forgiveness and empathy. Furthermore, the style of avoidant attachment to God and the style of bilateral attachment to God had a significantly negative relationship with forgiveness. In addition, the standard coefficients of all three predictive variables (Secure attachment, bilateral and avoidant to God were all significant at p=0.05. Assessment and recognition of the style of attachment to God, the students and its relation with forgiveness and empathy can have valuable implications in providing the mental health of the students. Conclusion: The findings of this research show a connection between the style of attachment to God and forgiveness and empathy, indicate the clarification of attachment to God in students' forgiveness and empathy. Based on the findings, it can be suggested that the theory of attachment to God can be used in psychotherapy.

    The current study investigated the relationship between parental attachment and depressive symptoms as well as the mediating effect of self-control in two different cultures. Samples were 1305 Chinese and 1327 Italian adolescents. They completed the Inventory of Parental and Peer Attachment, the Self-Restraint Subscale of the Adolescents' Self-Consciousness Scale, and the Children's Depression Inventory that assessed parental attachment, self-control, and depressive symptoms, respectively. Results showed that: (1) Few cultural differences in depressive symptom were observed. (2) Parental attachment and self-control were negatively related to depressive symptoms in both cultures. (3) Self-control mediated the relations between parental attachment and depressive symptoms in both cultures. (4) The direct and indirect effects were invariant across cultures. In conclusion, parental attachment and self-control are important for adolescents' depressive symptoms in Chinese and Italian adolescents. PMID:26132371

    Provoked vestibulodynia (PVD) is a prevalent women's sexual pain disorder, which is associated with sexual function difficulties. Attachment theory has been used to understand adult sexual outcomes, providing a useful framework for examining sexual adaptation in couples confronted with PVD. Research to date indicates that anxious and avoidant attachment dimensions correlate with worse sexual outcomes in community and clinical samples. The present study examined the association between attachment, pain, sexual function, and sexual satisfaction in a sample of 101 couples in which the women presented with PVD. The actor-partner interdependence model was used in order to investigate both actor and partner effects. This study also examined the role of sexual assertiveness as a mediator of these associations via structural equation modeling. Women completed measures of pain intensity and both members of the couple completed measures of romantic attachment, sexual assertiveness, sexual function, and satisfaction. Results indicated that attachment dimensions did not predict pain intensity. Both anxious and avoidant attachment were associated with lower sexual satisfaction. Only attachment avoidance predicted lower sexual function in women. Partner effects indicated that higher sexual assertiveness in women predicted higher sexual satisfaction in men. Finally, women's sexual assertiveness was found to be a significant mediator of the relationship between their attachment dimensions, sexual function, and satisfaction. Findings highlight the importance of examining how anxious and avoidant attachment may lead to difficulties in sexual assertiveness and to less satisfying sexual interactions in couples where women suffer from PVD.

    Bovine α-lactalbumin (α-La) contains numerous dipeptidyl peptidase IV (DPP-IV) inhibitory peptide sequences within its primary structure. In silico analysis indicated that the targeted hydrolysis of α-La with elastase should release DPP-IV inhibitory peptides. An α-La isolate was hydrolysed with elastase under different conditions using an experimental design approach incorporating 3 factors (temperature, pH and enzyme to substrate ratio (E : S) ratio) at 2 levels. The hydrolyzate generated at pH 8.5, 50 °C, E : S 2.0% (w/w) (H9) displayed the highest mean DPP-IV inhibition value at 3.1 mg mL(-1) of 75.8 ± 3.7% and had a half maximal DPP-IV inhibitory concentration (IC50) value of 1.20 ± 0.12 mg mL(-1). Five α-La-derived DPP-IV inhibitory peptides (GY, GL, GI, NY and WL) predicted to be released in silico were identified by liquid-chromatography tandem mass spectrometry (LC-MS/MS) within H9 and its simulated gastrointestinal digestion (SGID) sample. This preliminary study demonstrated the benefit of using a targeted approach combined with an experimental design in the generation of dietary protein hydrolyzates with DPP-IV inhibitory properties.

  20. Parental incarceration, attachment and child psychopathology.

    Murray, Joseph; Murray, Lynne

    2010-07-01

    Theory and evidence relating parental incarceration, attachment, and psychopathology are reviewed. Parental incarceration is a strong risk factor for long-lasting psychopathology, including antisocial and internalizing outcomes. Parental incarceration might threaten children's attachment security because of parent-child separation, confusing communication about parental absence, restricted contact with incarcerated parents, and unstable caregiving arrangements. Parental incarceration can also cause economic strain, reduced supervision, stigma, home and school moves, and other negative life events for children. Thus, there are multiple possible mechanisms whereby parental incarceration might increase risk for child psychopathology. Maternal incarceration tends to cause more disruption for children than paternal incarceration and may lead to greater risk for insecure attachment and psychopathology. Children's prior attachment relations and other life experiences are likely to be of great importance for understanding children's reactions to parental incarceration. Several hypotheses are presented about how prior insecure attachment and social adversity might interact with parental incarceration and contribute to psychopathology. Carefully designed longitudinal studies, randomized controlled trials, and cross-national comparative research are required to test these hypotheses.

    2013-03-01

    Vibrio cholerae is a gram-negative bacterium that causes the human disease cholera. It is found natively in brackish costal waters in temperate climates, where it attaches to the surfaces of a variety of different aquatic life. V. cholerae has a single polar flagellum making it highly motile, as well as a number of different pili types, enabling it to attach to both biotic and abiotic surfaces. Using in-house built tracking software we track all surface-attaching bacteria from high-speed movies to examine the early-time attachment profile of v. cholerae onto a smooth glass surface. Similar to previous work, we observe right-handed circular swimming trajectories near surfaces; however, in addition we see a host of distinct motility mechanisms that enable rapid exploration of the surface before forming a more permanent attachment. Using isogenic mutants we show that the motility mechanisms observed are due to a complex combination of hydrodynamics and pili-surface interactions. Lauga, E., DiLuzio, W. R., Whitesides, G.

    Full Text Available Insecure attachment styles have received theoretical attention and some initial empirical support as mediators between childhood adverse experiences and psychotic phenomena; however, further specificity needs investigating. The present interview study aimed to examine (i whether two forms of poor childhood care, namely parental antipathy and role reversal, were associated with subclinical positive and negative symptoms and schizophrenia-spectrum personality disorder (PD traits, and (ii whether such associations were mediated by specific insecure attachment styles.A total of 214 nonclinical young adults were interviewed for subclinical symptoms (Comprehensive Assessment of At-Risk Mental States, schizophrenia-spectrum PDs (Structured Clinical Interview for DSM-IV Axis II Disorders, poor childhood care (Childhood Experience of Care and Abuse Interview, and attachment style (Attachment Style Interview. Participants also completed the Beck Depression Inventory-II and all the analyses were conducted partialling out the effects of depressive symptoms.Both parental antipathy and role reversal were associated with subclinical positive symptoms and with paranoid and schizotypal PD traits. Role reversal was also associated with subclinical negative symptoms. Angry-dismissive attachment mediated associations between antipathy and subclinical positive symptoms and both angry-dismissive and enmeshed attachment mediated associations of antipathy with paranoid and schizotypal PD traits. Enmeshed attachment mediated associations of role reversal with paranoid and schizotypal PD traits.Attachment theory can inform lifespan models of how adverse developmental environments may increase the risk for psychosis. Insecure attachment provides a promising mechanism for understanding the development of schizophrenia-spectrum phenomenology and may offer a useful target for prophylactic intervention.

  3. Materials for generation-IV nuclear reactors

    International Nuclear Information System (INIS)

    Materials science and materials development are key issues for the implementation of innovative reactor systems such as those defined in the framework of the Generation IV. Six systems have been selected for Generation IV consideration: gas-cooled fast reactor, lead-cooled fast reactor, molten salt-cooled reactor, sodium-cooled fast reactor, supercritical water-cooled reactor, and very high temperature reactor. The structural materials need to resist much higher temperatures, higher neutron doses and extremely corrosive environment, which are beyond the experience of the current nuclear power plants. For this reason, the first consideration in the development of Generation-IV concepts is selection and deployment of materials that operate successfully in the aggressive operating environments expected in the Gen-IV concepts. This paper summarizes the Gen-IV operating environments and describes the various candidate materials under consideration for use in different structural applications. (author)

  9. Attachment theory: a biological basis for psychotherapy?

    1993-10-01

    John Bowlby bemoaned the separation between the biological and psychological approaches in psychiatry, and hoped that attachment theory, which brings together psychoanalysis and the science of ethology, would help bridge the rift between them. Recent findings in developmental psychology have delineated features of parent-infant interaction, especially responsiveness, attunement, and modulation of affect, which lead to either secure or insecure attachment. Similar principles can be applied to the relationship between psychotherapist and patient--the provision of a secure base, the emergence of a shared narrative ('autobiographical competence'), the processing of affect, coping with loss--these are common to most effective psychotherapies and provide the basis for a new interpersonal paradigm within psychotherapy. Attachment theory suggests they rest on a sound ethological and hence biological foundation.

    Rothbaum, Fred; Rosen, Karen; Ujiie, Tatsuo; Uchida, Nobuko

    2002-01-01

    Family systems theory and attachment theory have important similarities and complementarities. Here we consider two areas in which the theories converge: (a) in family system theorists' description of an overly close, or "enmeshed," mother-child dyad, which attachment theorists conceptualize as the interaction of children's ambivalent attachment and mothers' preoccupied attachment; (b) in family system theorists' description of the "pursuer-distance cycle" of marital conflict, which attachment theorists conceptualize as the interaction of preoccupied and dismissive partners. We briefly review family systems theory evidence, and more extensively review attachment theory evidence, pertaining to these points of convergence. We also review cross-cultural research, which leads us to conclude that the dynamics described in both theories reflect, in part, Western ways of thinking and Western patterns of relatedness. Evidence from Japan suggests that extremely close ties between mother and child are perceived as adaptive, and are more common, and that children experience less adverse effects from such relationships than do children in the West. Moreover, in Japan there is less emphasis on the importance of the exclusive spousal relationship, and less need for the mother and father to find time alone to rekindle romantic, intimate feelings and to resolve conflicts by openly communicating their differences. Thus, the "maladaptive" pattern frequently cited by Western theorists of an extremely close mother-child relationship, an unromantic, conflictual marriage characterized by little verbal communication and a peripheral, distant father, may function very differently in other cultures. While we believe that both theories will be greatly enriched by their integration, we caution against the application of either theory outside the cultures in which they were developed.

    This article reports on the Adolescent Unresolved Attachment Questionnaire (AUAQ), a brief questionnaire that assesses the caregiving experiences of unresolved adolescents (as recipients of caregiving). The AUAQ was developed and validated in a large normative sample (n = 691) and a sample of 133 adolescents in psychiatric treatment. It is a self-report questionnaire consisting of 3 scales with Likert-type responses ranging from strongly disagree to strongly agree. The Aloneness/Failed Protection Scale assesses the adolescent's perception of the care provided by the attachment figure. The Fear Scale taps the fear generated by the adolescent's appraisal of failed attachment figure care. The Anger/Dysregulation Scale assesses negative affective responses to the perceived lack of care from the attachment figure. All scales demonstrated satisfactory internal reliability and agreement between scores for adolescents (n = 91) from the normative sample who completed the AUAQ twice. Adolescents in the clinical sample also completed the Adult Attachment Interview (AAI; C. George, N. Kaplan, & M. Main, 1984/1985/1996); the AUAQ demonstrated high convergent validity with the AAI.

    The aim of this study was to determine the prevalence of midline diastema, tongue tie and frenum attachments amongst school children in Nairobi. A total of 1802 children aged between 4 and 16 years were selected randomly using multistage sampling technique. To avoid oversampling in either sex, a proportionate sampling procedure was used. Thereafter, a thorough intra-oral examination was carried out using a mouth mirror under artificial or natural light with the children lying on a supine position. Presence or absence of midline interdental spaces unusually bigger than other interdental spaces were noted and recorded on a prepared dateacollection form. Accurate location of the origin of the frenum was done using Placek et al Morphological-functional classification of the labial frenum attachments. Data was analyzed manually by tally method. Results showed that 35% had upper and lower midline diastema. 55% were females and 45% were males. Their mean age was 7.6 years. 0.2% had a high lingual frenum. The commonest location of frenum attachment amongst children with lower midline diastema was the mucogingival junction (86%) whereas amongst those with upper midline diastema it was attached gingiva (50%). None of the children had frenum attachment on the interdental papilla. It was concluded that the maxilla had a higher prevalence of midline diastema than the mandible and that papillary penetrating frenum attachments amongst these patients were higher in the maxilla than the mandible.

    In this paper, we analyze assortativity of preferential attachment models. We deal with a wide class of preferential attachment models (PA-class). It was previously shown that the degree distribution in all models of the PA-class follows a power law. Also, the global and the average local clustering coefficients were analyzed. We expand these results by analyzing the assortativity property of the PA-class of models. Namely, we analyze the behavior of $d_{nn}(d)$ which is the average degree of a neighbor of a vertex of degree $d$.

    2008-12-01

    This study examines the influence of mother-child and family interactions on the development of child attachment representations in middle childhood for a sample of 49 families. Mother-child interactions were observed during a snacktime in a lab setting (Moss, Rousseau, Parent, St-Laurent, & Saintonge, 1998) when children were 5-6 years old. Three years later, children's attachment representations were assessed using a doll play narrative procedure (Solomon, George, & DeJong, 1995) in the lab setting. Within 6 months of the second lab visit, family interactions were filmed during mealtime and coded using the Mealtime Interaction Coding System (MICS; Dickstein, Hayden, Schiller, Seifer, & San Antonio, 1994). Results showed clear differences between attachment groups on quality of mother-child and family interaction with the secure/confident group showing highest and the disorganized/frightened group showing lowest quality interactions. Family interactions predicted children's attachment representations, after controlling variance explained by prior mother-child interactions.

    2016-01-01

    The influence of the composition and microstructure of different carbon steel grades on the initial attachment (≤ 60 min) of Escherichia coli and subsequent longer term (28 days) corrosion was investigated. The initial bacterial attachment increased with time on all grades of carbon steel. However, the rate and magnitude of bacterial attachment varied on the different steel grades and was significantly less on the steels with a higher pearlite phase content. The observed variations in the number of bacterial cells attached across different steel grades were significantly reduced by applying a fixed potential to the steel samples. Longer term immersion studies showed similar levels of biofilm formation on the surface of the different grades of carbon steel. The measured corrosion rates were significantly higher in biotic conditions compared to abiotic conditions and were found to be positively correlated with the pearlite phase content of the different grades of carbon steel coupons.

    2007-07-01

    The European Energy Law Report IV presents an overview of the most important legal developments in the field of EU and national energy law as discussed at the 2006 European Energy Law Seminar. It examines recent developments in EU and National Law affecting the energy sector. This includes the increasing use of EU competition law to liberalise the energy markets, the long-awaited implementation of the 2003 Electricity and Gas Directives in Germany and an assessment of Regulation 1775/2005 and its effect on the European gas market. Besides the energy market liberalisation, the Community is increasingly paying attention to the need for a sustainable and clean energy supply. The second part of the book therefore includes chapters on legal issues resulting from the experiences on emission trading in 2005-2007, the regulatory challenges resulting from the new Commission Energy Policy, the impact of the Amsterdam and Berlin Fora on EU Energy policy, and the EU policy framework on energy efficiency. An important tool for improving energy efficiency is the introduction of white certificates. The third part of the report presents the basic principles of white certificates as well as practical experiences and policies in some member states like Italy, France, The Netherlands and the UK. The final part of the report considers several issues related to the development and use of subsea electricity interconnectors and pays special attention to the development of the NorNed cable. It raises the need for a Treaty perspective on the developments of such subsea interconnectors. Then some regulatory views on the development of the NorNed cable and market coupling through the cable are presented. Finally, the economic and regulatory distinction between regulated and merchant interconnectors is discussed.

    As part of a study to characterize the detailed coordination behavior of Pu(IV), single crystal X-ray diffraction structures have been determined for Pu(IV) and Ce(IV) complexes with the naturally-occurring ligand maltol (3-hydroxy-2-methyl-pyran-4-one) and its derivative bromomaltol (5-bromo-3-hydroxy-2-methyl-pyran-4-one). Although Ce(IV) is generally accepted as a structural analog for Pu(IV), and the maltol complexes of these two metals are isostructural, the corresponding bromomaltol complexes are strikingly different with respect to ligand orientation about the metal ion: All complexes exhibit trigonal dodecahedral coordination geometry but the Ce(IV)-bromomaltol complex displays an uncommon ligand arrangement not mirrored in the Pu(IV) complex, although the two metal species are generally accepted to be structural analogs.

    A key proposition of attachment theory is that experience-based cognitive representations of attachment, often referred to as internal working models of attachment, influence the manner in which individuals process attachment-relevant social information (Bowlby, 1969/1982, 1973, 1980; Bretherton & Munholland, 1999; Main, Kaplan, & Cassidy, 1985).…

    2012-05-01

    Two issues pertinent to the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) proposal for personality pathology, the recovery of DSM-IV personality disorders (PDs) by proposed DSM-5 traits and the validity of the proposed DSM-5 hybrid model, which incorporates both personality pathology symptoms and maladaptive traits, were evaluated in a large undergraduate sample (N = 808). Proposed DSM-5 traits as assessed with the Personality Inventory for DSM-5 explained a substantial proportion of variance in DSM-IV PDs as assessed with the Personality Diagnostic Questionnaire-4+, and trait indicators of the 6 proposed DSM-5 PDs were mostly specific to those disorders with some exceptions. Regression analyses support the DSM-5 hybrid model in that pathological traits, and an indicator of general personality pathology severity provided incremental information about PDs. Findings are discussed in the context of broader issues around the proposed DSM-5 model of personality disorders.

Objectives The aim of this study was to determine attachment styles in people with GID and compare them with normal people in Fars province, Iran. Materials and Methods This case-control study with accessible sampling was conducted in Fars province, Iran, in 2014 using 60 visitors to the Fars province forensics head office who had been diagnosed as having GID by the commission of psychology (the case group and 204 individuals in dispose, whom psychologists diagnosed as having no psychological disorder and in synchronization with the sample group (controls. The demographic questionnaire and Collins and Read attachment style questionnaires were used in both groups. Data were collected and then analyzed using the SPSS software version 18, Kormogrov Smirnov’s normality test and Pearson’s correlation coefficient. A significance level of P < 0.05 was considered significant. Results Findings showed that the highest frequency (71% in terms of secure attachment and the lowest frequency (0% in terms of avoidant attachment were observed in patients with GID who had been operated and the highest frequency of avoidant attachment (62.1% and the lowest frequency of secure attachment (0% were observed in patients with GID who had not been operated. Conclusions According to the findings of this study, GID patients who have been operated are more secure in attachment styles than those who have not been operated, and there is a significant correlation between age, education and gender with attachment style among these individuals.

    2013-04-01

    A lathe attachment has been developed for an existing CNC machine (installed with rapid prototyping attachment) using conceptual design. The CNC machine operates on mechatronic controls and a computer interface called CAMSOFT, and is used as a CNC Lathe after installing the respective attachment to it. The conceptual design phase, starts from an idea and different components of the lathe are designed as attachment using CAD modelling and is followed by fabrication phase. The lathe attachment is successfully developed and is installed to the CNC machine. The working of the CNC Lathe attachment is checked by making some machining operation like turning and thread cutting. The machining operations are successfully done. The CNC machine becomes multifunctional with the presently developed lathe attachment and the existing RP (rapid prototyping) attachment, and can be used accordingly by installing the respective attachment to it. The CNC machine is useful for carrying research work in both the fields, when installed with the appropriate attachment.

    Full Text Available We study the I-V characteristic of mesoscopic systems or quantum dot (QD attached to a pair of superconducting leads. Interaction effects in the QD are considered through the charging energy of the QD; that is, the treatment of current transport under a voltage bias is performed within a coupled Poisson nonequilibrium Green function (PNEGF formalism. We derive the expression for the current in full generality but consider only the regime where transport occurs only via a single particle current. We show for this case and for various charging energies values U0 and associated capacitances of the QD the effect on the I-V characteristic. Also the influence of the coupling constants on the I-V characteristic is investigated. Our approach puts forward a novel interpretation of experiments in the strong Coulomb regime.

    Leptospira interrogans is the etiological agent of leptospirosis, a zoonotic disease that affects populations worldwide. We have identified in proteomic studies a protein that is encoded by the gene LIC10314 and expressed in virulent strain of L. interrogans serovar Pomona. This protein was predicted to be surface exposed by PSORT program and contains a p83/100 domain identified by BLAST analysis that is conserved in protein antigens of several strains of Borrelia and Treponema spp. The proteins containing this domain have been claimed antigen candidates for serodiagnosis of Lyme borreliosis. Thus, we have cloned the LIC10314 and expressed the protein in Escherichia coli BL21-SI strain by using the expression vector pAE. The recombinant protein tagged with N-terminal hexahistidine was purified by metal-charged chromatography and characterized by circular dichroism spectroscopy. This protein is conserved among several species of pathogenic Leptospira and absent in the saprophytic strain L. biflexa. We confirm by liquid-phase immunofluorescence assays with living organisms that this protein is most likely a new surface leptospiral protein. The ability of the protein to mediate attachment to ECM components was evaluated by binding assays. The leptospiral protein encoded by LIC10314, named Lsa63 (Leptospiral surface adhesin of 63kDa), binds strongly to laminin and collagen IV in a dose-dependent and saturable fashion. In addition, Lsa63 is probably expressed during infection since it was recognized by antibodies of serum samples of confirmed-leptospirosis patients in convalescent phase of the disease. Altogether, the data suggests that this novel identified surface protein may be involved in leptospiral pathogenesis.

    2011-05-01

    A dimorphic life cycle has been described for the planctomycete Rhodopirellula baltica SH1(T), with juvenile motile, free-swimming cells and adult sessile, attached-living cells. However, attachment as a response to environmental factors was not investigated. We studied the response of R. baltica to nitrogen limitation. In batch cultures, ammonium limitation coincided with a dominance of free-swimming cells and a low number of aggregates. Flow cytometry revealed a quantitative shift with increasing ammonium availability, from single cells towards attached cells in large aggregates. During growth of R. baltica on glucose and ammonium in chemostats, an ammonium addition caused a macroscopic change of the growth behaviour, from homogeneous growth in the liquid phase to a biofilm on the borosilicate glass wall of the chemostat vessel. Thus, an ammonium limitation-a carbon to nitrogen supply ratio of 30:1-sustained free-living growth without aggregate formation. A sudden increase in ammonium supply induced sessile growth of R. baltica. These observations reveal a response of Rhodopirellula baltica cells to ammonium: they abandon the free-swimming life, attach to particles and form biofilms. PMID:21340506

    Partis, M

    2000-10-01

    This article reviews the current state of research in attachment theory. It also examines the relations between attachment, child care and development, and the significance of attachment to adult functioning and well-being. It seems likely that humans need close emotional relationships or bonds with others. This need applies particularly to infants, who look to parents or other care givers for love and security. The best-known psychological explanation of this need is attachment theory, which has been influential in increasing our understanding of the early mother-infant relationship, and in the formulation of guidelines for child care (Melhuish, 1998). Good-quality parental care may be difficult to define, and questions remain regarding the nature of child care and the consequences that it can have for later development. This article concludes with a discussion of the possible implications for health-visitor intervention within families, which are intended to improve the quality of the relationship between parents or care givers and the infant.

    Behrens, Kazuko Y; Haltigan, John D; Bahm, Naomi I Gribneau

    2016-08-01

    This study investigated the intergenerational transmission of attachment, utilizing the Adult Attachment Interview (AAI), the Strange Situation Procedure (SSP), and the Maternal Behavioral Q-Set (MBQS). We revisited fundamental questions in attachment theory and research by examining: (1) the level of intergenerational agreement between maternal attachment representations and infant attachment security, and (2) whether maternal sensitivity serves as an intergenerational mediator between adult and infant attachment security. Significant categorical matches between the AAI and the SSP as well as mean differences for MBQS scores between adult attachment secure-insecure groups were found. Consistent with earlier intergenerational research, maternal sensitivity only partially mediated the AAI-SSP link, indicating the transmission gap remains. Consistent with recent mediation studies, using more contemporary analytical techniques, it was confirmed that maternal sensitivity did mediate the direct pathway between AAI security and SSP security. Thus, the transmission gap appears somewhat different depending on the statistical method used to measure mediation. Post hoc analyses considered mothers' childhood experiences of separation/divorce and this helped make sense of intergenerational mismatches.

    Do Attachment Styles of Mentally Ill Parents Impact on the Health-related Quality of Life of their Children? Parents with a mental disorder often display a problematic attachment style which may impact on their children's health related quality of life (HrQoL). The current study cross-sectionally examines attachment styles (BEPE) in mentally ill parents with underage children (n = 62) and the effect of attachment on their children's HrQoL (KINDL-R). Results show that secure attachment is less represented in parents with a mental health condition than in a healthy reference group. Within the clinical sample, children of mentally ill parents with a secure attachment style exhibit a higher HrQoL than children of mentally ill parents with ambivalent or avoidant attachment styles. These findings indicate not only that problematic attachment styles frequently occur in families with a mentally ill parent, but also suggest that this negatively affects the children's HrQoL. Appropriate interventions should include attachment oriented concepts. PMID:27027217

    Despite being a universal human attachment behavior, little is known about individual differences in crying. To facilitate such examination we first recommend shortened versions of the attitudes and proneness sections of the Adult Crying Inventory using two independent samples. Importantly, we examine attachment orientation differences in crying proneness and test the mediating role of attitudes toward crying in this relationship. Participants (Sample 1 N = 623, Sample 2 N = 781), completed online measures of adult attachment dimensions (avoidance and anxiety), attitudes toward crying, and crying proneness. Exploratory factor analyses in Sample 1 revealed four factors for crying attitudes: crying helps one feel better; crying is healthy; hatred of crying; and crying is controllable; and three factors for crying proneness: threat to self; sadness; and joy. Confirmatory factor analyses in Sample 2 replicated these structures. Theoretically and statistically justified short forms of each scale were created. Multiple mediation analyses revealed similar patterns of results across the two samples, with the attitudes "crying is healthy" and "crying is controllable" consistently mediating the positive links between attachment anxiety and crying proneness, and the negative links between attachment avoidance and crying proneness. Results are discussed in relation to attachment and emotion regulation literature. PMID:27458402

    Photoemission electron attachment ion mobility spectrometry (PE-EA-IMS), with a source of photoelectrons induced by vacuum ultraviolet radiation on a metal surface, has been developed to study electron attachment reaction at atmospheric pressure using nitrogen as the buffer gas. Based on the negative ion mobility spectra, the rate constants for electron attachment to tetrachloromethane and chloroform were measured at ambient temperature as a function of the average electron energy in the range from 0.29 to 0.96 eV. The experimental results are in good agreement with the data reported in the literature.

    A light water reactor fuel behavior analysis code FEMAXI-IV(Ver.2) was developed as an improved version of FEMAXI-IV. Development of FEMAXI-IV has been already finished in 1992, though a detailed structure and input manual of the code have not been open to users yet. Here, the basic theories and structure, the models and numerical solutions applied to FEMAXI-IV(Ver.2), and the material properties adopted in the code are described in detail. In FEMAXI-IV(Ver.2), programming bugs in previous FEMAXI-IV were eliminated, renewal of the pellet thermal conductivity was performed, and a model of thermal-stress restraint on FP gas release was incorporated. For facilitation of effective and wide-ranging application of the code, methods of input/output of the code are also described in detail, and sample output is included. (author)

    Intelligence testing is used for many purposes including identification of children for proper educational placement (e.g., children with learning disabilities, or intellectually gifted students), and to guide education by identifying cognitive strengths and weaknesses so that teachers can adapt their instructional style to students' specific learning styles. Most of the research involving intelligence tests has been conducted in highly developed Western countries, yet the need for intelligence testing is as or even more important in developing countries. The present study, conducted through the Vietnam National University Clinical Psychology CRISP Center, focused on the cultural adaptation of the WISC-IV intelligence test for Vietnam. We report on (a) the adaptation process including the translation, cultural analysis and modifications involved in adaptation, (b) present results of two pilot studies, and (c) describe collection of the standardization sample and results of analyses with the standardization sample, with the goal of sharing our experience with other researchers who may be involved in or interested in adapting or developing IQ tests for non-Western, non-English speaking cultures.

    Full Text Available Abstract Background Dentin sialophosphoprotein (Dspp is a multidomain, secreted protein that is critical for the formation of tooth dentin. Mutations in DSPP cause inherited dentin defects categorized as dentin dysplasia type II and dentinogenesis imperfecta type II and type III. Dentin sialoprotein (Dsp, the N-terminal domain of dentin sialophosphoprotein (Dspp, is a highly glycosylated proteoglycan, but little is known about the number, character, and attachment sites of its carbohydrate moieties. Results To identify its carbohydrate attachment sites we isolated Dsp from developing porcine molars and digested it with endoproteinase Glu-C or pronase, fractionated the digestion products, identified fractions containing glycosylated peptides using a phenol sulfuric acid assay, and characterized the glycopeptides by N-terminal sequencing, amino acid analyses, or LC/MSMS. To determine the average number of sialic acid attachments per N-glycosylation, we digested Dsp with glycopeptidase A, labeled the released N-glycosylations with 2-aminobenzoic acid, and quantified the moles of released glycosylations by comparison to labeled standards of known concentration. Sialic acid was released by sialidase digestion and quantified by measuring β-NADH reduction of pyruvic acid, which was generated stoichiometrically from sialic acid by aldolase. To determine its forms, sialic acid released by sialidase digestion was labeled with 1,2-diamino-4,5-methyleneoxybenzene (DMB and compared to a DMB-labeled sialic acid reference panel by RP-HPLC. To determine the composition of Dsp glycosaminoglycan (GAG attachments, we digested Dsp with chondroitinase ABC and compared the chromotagraphic profiles of the released disaccharides to commercial standards. N-glycosylations were identified at Asn37, Asn77, Asn136, Asn155, Asn161, and Asn176. Dsp averages one sialic acid per N-glycosylation, which is always in the form of N-acetylneuraminic acid. O-glycosylations were

    Gas-phase formation of temporary negative ion states via resonance attachment of low-energy (0-6 eV) electrons into vacant molecular orbitals of salicylic acid (I) and its derivatives 3-hydroxy- (II) and 4-hydroxybenzoic acid (III), 5-cloro salicylic acid (IV) and methyl salicylate (V) was investigated for the first time by electron transmission spectroscopy. The description of their empty-level structures was supported by density functional theory and Hartree-Fock calculations, using empirically calibrated linear equations to scale the calculated virtual orbital energies. Dissociative electron attachment spectroscopy (DEAS) was used to measure the fragment anion yields generated through dissociative decay channels of the parent molecular anions of compounds I-V, detected with a mass filter as a function of the incident electron energy in the 0-14 eV energy range. The most intense negative fragment produced by DEA to isomers I-III is the dehydrogenated molecular anion [M-H]-, mainly formed at incident electron energies around 1 eV. The vertical and adiabatic electron affinities were evaluated at the B3LYP/6-31+G(d) level as the anion/neutral total energy difference. The same theoretical method was also used for evaluation of the thermodynamic energy thresholds for production of the negative fragments observed in the DEA spectra. The gas-phase DEAS data can provide support for biochemical reaction mechanisms in vivo.

    2013-01-01

    We examined whether hostile dominant interpersonal problems (HDIP), antisocial features, and borderline features mediated the relationship between attachment (anxiety or avoidance) and intimate partner violence (IPV) with a sample of 132 male partner abusers. We conducted two path analyses with avoidant attachment as the predictor in one model and anxious attachment as the predictor in a second model. In both models, HDIP, antisocial features, and borderline features were the mediators with IPV as the criterion. For both models, the attachment variable had statistically significant path values to the mediating variables. However, neither antisocial nor borderline features had statistically significant path values from the mediating variable to the criterion variable (IPV). Only HDIP had a statistically significant path value from the mediating variable to the criterion variable in both models. However, only the avoidant model produced a statistically significant specific indirect effect indicating that HDIP clearly mediated the relationship between attachment and IPV. Results suggest that partner abusive men with predominantly avoidant and, to a lesser degree, anxious attachment may be at increased risk for addressing conflicts in a coercive, controlling, and vengeful manner that is manifested in physical aggression toward a partner. Further, interpersonal constructs may be better measures of psychopathology and provide more relevant clinical targets than personality constructs with male partner abusers.

    Microbes tend to attach to available surfaces and readily form biofilms, which is problematic in healthcare settings. Biofilms are traditionally associated with wet or damp surfaces such as indwelling medical devices and tubing on medical equipment. However, microbes can survive for extended periods in a desiccated state on dry hospital surfaces, and biofilms have recently been discovered on dry hospital surfaces. Microbes attached to surfaces and in biofilms are less susceptible to biocides, antibiotics and physical stress. Thus, surface attachment and/or biofilm formation may explain how vegetative bacteria can survive on surfaces for weeks to months (or more), interfere with attempts to recover microbes through environmental sampling, and provide a mixed bacterial population for the horizontal transfer of resistance genes. The capacity of existing detergent formulations and disinfectants to disrupt biofilms may have an important and previously unrecognized role in determining their effectiveness in the field, which should be reflected in testing standards. There is a need for further research to elucidate the nature and physiology of microbes on dry hospital surfaces, specifically the prevalence and composition of biofilms. This will inform new approaches to hospital cleaning and disinfection, including novel surfaces that reduce microbial attachment and improve microbial detachment, and methods to augment the activity of biocides against surface-attached microbes such as bacteriophages and antimicrobial peptides. Future strategies to address environmental contamination on hospital surfaces should consider the presence of microbes attached to surfaces, including biofilms.

  15. Trust, attachment, and mindfulness influence intimacy and disengagement during newlyweds' discussions of relationship transgressions.

    Discussions of relationship transgressions-violations of relationship norms-are often difficult for couples to successfully navigate. Nevertheless, engaging in and resolving these discussions should promote intimacy. Drawing on the risk regulation model, individuals' experiences of disengagement and intimacy during transgression discussions should depend on their trust in their partner regarding the transgression and how they regulate distress related to lower trust. Attachment style represents individual differences in emotion regulation in close relationship contexts and is indicated by the risk regulation model. In contrast, mindfulness also improves interpersonal emotion regulation but is not reflected in the model. The present study proposed that the effect of trust on the experience of intimacy and disengagement during transgression discussions would depend on individuals' attachment style or mindfulness. Hypotheses were tested in a sample of 81 heterosexual newlywed couples. Trust was positively associated with intimacy for individuals with higher attachment avoidance, but not for individuals with lower attachment avoidance. Trust was negatively associated with disengagement for individuals with either lower mindfulness or higher attachment avoidance. Trust was not associated with disengagement for individuals with higher mindfulness or lower attachment avoidance. Implications for theory and clinical interventions focused on increasing intimacy and decreasing disengagement in couple relationships are discussed. (PsycINFO Database Record PMID:27077236

    Wildfires are a common occurrence in many countries and are predicted to increase as we experience the effects of climate change. As more people are expected to be affected by fires, it is important to increase people's wildfire mitigation and preparation. Place attachment has been theorized to be related to mitigation and preparation. The present study examined place attachment and wildfire mitigation and preparation in two Australian samples, one rural and one on the wildland-urban interface. The study consisted of 300 participants who responded to questionnaires about their place attachment to their homes and local areas, as well as describing their socio-demographic characteristics and wildfire mitigation and preparedness. Hierarchical regression showed that place attachment to homes predicted wildfire mitigation and preparedness in the rural sample but not in the wildland-urban interface sample. The results suggest that place attachment is a motivator for mitigation and preparation only for people living rurally. Reminding rural residents of their attachment to home at the beginning of wildfire season may result in greater mitigation and preparedness. Further research focusing on why attachment does not predict mitigation and preparedness in the wildland-urban interface is needed.

    Full Text Available Measuring Place Attachment to Călimani National Park (Romania among Local Residents and Tourists. Preliminary Findings. Understanding the attachments that people develop for certain places is an interesting area of study, but with little attention in Romanian empirical research. This study introduces the concepts of place identity and place dependence in relation to a specific area within the local culture of the Land of Dorna. Starting from previous studies carried on western samples, a research instrument measuring the degree and content of place attachment was translated and adapted. 86 respondents (52 residents and 34 tourists filled in the questionnaire. Comparing the degree of attachment, there was no significant difference among the two samples. However, local residents tended to display higher levels of place identity, while tourists displayed more emotional functionality to the study area. Place attachment is deeply embodied in the local culture. Due to the research design the generalization of the results is limited. However, this study may act as a starting point in researching other geographical mental spaces. The lands of Romania are unique social and cultural spaces with specific attachment patterns. Future studies should consider larger and representative samples in order to find additional patterns of attachment among residents and other individuals (e.g. tourists, visitors, new residents, other communities etc..

    The aim of this study was to further explore the properties of axis IV in the Diagnostic and statistical manual of mental disorders, 4th edition (DSM-IV). In a naturalistic cross-sectional design, a group (n = 163) of young (18-25 years old) Swedish psychiatric outpatients was assessed according to DSM-IV. Psychosocial and environmental problems/axis IV were evaluated through structured interviewing by a social worker and by self-assessment on a questionnaire. Reliability between professional assessment and self-assessment of axis IV was examined. Concurrent validity of axis IV was also examined. Reliability between professional and self-assessed axis IV was fair to almost perfect, 0.31-0.83, according to prevalence and bias-adjusted kappa. Categories of psychosocial stress and environmental problems were related to the presence of axis I disorders, co-morbidity, personality disorders and decreasing Global Assessment of Functioning (GAF) values. The revised axis IV according to DSM-IV seems to have concurrent validity, but is still hampered by limited reliability.

    Peste des petits ruminants virus (PPRV) is the cause agent of peste des petitis ruminants (PPR). A novel lineage IV PPRV has reemerged in China in 2013 and 2014. Mass vaccination was implemented in most provinces in China. In order to detect lineage IV PPRV in clinical samples and to distinguish rapidly it from the other lineages PPRVs, a real-time RT-PCR assay was developed. This assay showed high sensitivity, specificity and efficiency in differentiating the lineage IV PPRV from others. The performance of this assay was evaluated by positive clinical samples of lineage IV viruses. This new real-time RT-PCR assay will facilitate epidemiological investigations and rapid differentiatial diagnosis in areas where lineage IV viruses are circulating. PMID:27260657

    Bowlby's attachment theory is a theory of psychopathology as well as a theory of normal development. It contains clear and specific propositions regarding the role of early experience in developmental psychopathology, the importance of ongoing context, and the nature of the developmental process underlying pathology. In particular, Bowlby argued that adaptation is always the joint product of developmental history and current circumstances (never either alone). Early experience does not cause later pathology in a linear way; yet, it has special significance due to the complex, systemic, transactional nature of development. Prior history is part of current context, playing a role in selection, engagement, and interpretation of subsequent experience and in the use of available environmental supports. Finally, except in very extreme cases, early anxious attachment is not viewed as psychopathology itself or as a direct cause of psychopathology but as an initiator of pathways probabilistically associated with later pathology.

    This paper presents a theoretical study of the frequency pulling effect exerted on a DFB laser by an external amplitude modulator that is directly attached to it. The modulator consists of a piece of waveguide whose loss is modulated by means of an externally applied voltage. The modulator affects the laser due to residual reflections from its far end which appear as a variable effective reflectivity to the output end of the DFB laser. Modulation affects the magnitude as well as the phase of the effective reflection coefficient presented to the laser due to the coupling of the real and imaginary parts of the effective refractive index of the modulator waveguide. The tuning problem is formulated as an eigenvalue equation for the DFB laser in the presence of an externally attached lossy cavity.

    This study investigated how perceptions of current dating partners and relationships change after people with different attachment orientations attempt to resolve a problem in their relationship. Dating couples were videotaped while they tried to resolve either a major or a minor problem. Confirming predictions from attachment theory, men and women who had a more ambivalent orientation perceived their partner and relationship in relatively less positive terms after discussing a major problem. Observer ratings revealed that more ambivalent women who tried to resolve a major problem displayed particularly strong stress and anxiety and engaged in more negative behaviors. Conversely, men with a more avoidant orientation were rated as less warm and supportive, especially if they discussed a major problem. These results are discussed in terms of how highly ambivalent and highly avoidant people differentially perceive and respond to distressing events.

    Emotional dysregulation and impaired attachment are seen by many clinical researchers as central aspects of borderline personality disorder (BPD). Alternatively, these constructs may represent general impairments in personality that are nonspecific to BPD. Using multitraitmultimethod models, the authors examined the strength of associations among preoccupied attachment, difficulties with emotion regulation, BPD features, and features of two other personality disorders (i.e., antisocial and avoidant) in a combined psychiatric outpatient and community sample of adults. Results suggested that preoccupied attachment and difficulties with emotion regulation shared strong positive associations with each other and with each of the selected personality disorders. However, preoccupied attachment and emotional dysregulation were more strongly related to BPD features than to features of other personality disorders. Findings suggest that although impairments in relational and emotional domains may underlie personality pathology in general, preoccupied attachment and emotional dysregulation also have specificity for understanding core difficulties in those with BPD.

    This study examined a multiple mediator model explaining how sibling perpetration and one's attachment style mediate the relation between parent-to-child victimization and dating violence perpetration. A sample of undergraduate students (n = 392 women, n = 89 men) completed measures of the aforementioned variables on an Internet survey. For men, path analyses found no mediation; parent-to-child victimization had a direct association with dating violence perpetration, no association was found between sibling perpetration and dating violence perpetration, and attachment anxiety, but not attachment avoidance, was positively associated with dating violence perpetration for men. For women, the hypothesized mediation model was supported; parent-to-child victimization had a direct association with dating violence perpetration, and sibling perpetration and attachment anxiety served as mediating variables. Attachment avoidance was not associated with dating violence perpetration for women. Implications for future research and clinical practice are discussed. PMID:24097907

    The purpose of this study was to examine links between parenting dimensions (authoritative parenting, psychological control, and parental authority) and adolescent wellbeing (self-esteem, autonomy, and peer attachments) as mediated by parent-teen attachment, among Chinese families. The sample included 298 Chinese adolescents, ages 15-18 years (M(age) = 16.36, SD = .68; 60% female). The mediation model was examined using path analyses (one model with parental authority as overprotection, and one with it as perceived behavioral control). To improve model fit a direct path was added from authoritative parenting to autonomy. Authoritative parenting was positively predictive of attachment, while psychological control and overprotection (but not behavioral control) were negative predictors. In turn, adolescent-parent attachment was positively related to the three outcomes. Lastly, the model paths did not differ by adolescent gender. These findings suggest that parenting behaviors may play a crucial role in adolescent social behaviors and wellbeing via adolescent-parent attachment. PMID:23509911

    The addition of insulation to the exterior of buildings is an effective means of increasing the thermal resistance of both wood framed walls as well as mass masonry wall assemblies. For thick layers of exterior insulation (levels greater than 1.5 inches), the use of wood furring strips attached through the insulation back to the structure has been used by many contractors and designers as a means to provide a convenient cladding attachment location (Straube and Smegal 2009, Pettit 2009, Joyce 2009, Ueno 2010). The research presented in this report is intended to help develop a better understanding of the system mechanics involved and the potential for environmental exposure induced movement between the furring strip and the framing. BSC sought to address the following research questions: 1.What are the relative roles of the mechanisms and the magnitudes of the force that influence the vertical displacement resistance of the system? 2.Can the capacity at a specified deflection be reliably calculated using mechanics based equations? 3.What are the impacts of environmental exposure on the vertical displacement of furring strips attached directly through insulation back to a wood structure?

  20. Integrin Expression Regulates Neuroblastoma Attachment and Migration

    2004-07-01

    Full Text Available Neuroblastoma (NBL is the most common malignant disease of infancy, and children with bone metastasis have a mortality rate greater than 90%. Two major classes of proteins, integrins and growth factors, regulate the metastatic process. We have previously shown that tumorigenic NBL cells express higher levels of the type I insulin-like growth factor receptor (IGF-IR and that β1 integrin expression is inversely proportional to tumorigenic potential in NBL. In the current study, we analyze the effect of β1 integrin and IGF-IR on NBL cell attachment and migration. Nontumorigenic S-cells express high levels of β1 integrin, whereas tumorigenic N-cells express little β1 integrin. Alterations in (3, integrin are due to regulation at the protein level, as translation is decreased in N-type cells. Moreover, inhibition of protein synthesis shows that β1 integrin is degraded more slowly in S-type cells (SHEP than in N-type cells (SH-SY5Y and IMR32. Inhibition of α5β1 integrin prevents SHEP (but not SH-SY5Y or IMR32 cell attachment to fibronectin and increases SHEP cell migration. Increases in IGF-IR decrease β1 integrin expression, and enhance SHEP cell migration, potentially through increased expression of αvβ3. These data suggest that specific classes of integrins in concert with IGF-IR regulate NBL attachment and migration.
