Infections due to Clostridioides difficile (previously known as Clostridium difficile) are a major problem in hospitals, where cases can be caused by community-acquired strains as well as by nosocomial spread. Whole genome sequences from clinical samples contain a lot of information but that needs to be analyzed and compared in such a way that the outcome is useful for clinicians or epidemiologists. Here, we compare 663 public available complete genome sequences of C. difficile using average amino acid identity (AAI) scores. This analysis revealed that most of these genomes (640, 96.5%) clearly belong to the same species, while the remaining 23 genomes produce four distinct clusters within the Clostridioides genus. The main C. difficile cluster can be further divided into sub-clusters, depending on the chosen cutoff. We demonstrate that MLST, either based on partial or full gene-length, results in biased estimates of genetic differences and does not capture the true degree of similarity or differences of complete genomes. Presence of genes coding for C. difficile toxins A and B (ToxA/B), as well as the binary C. difficile toxin (CDT), was deduced from their unique PfamA domain architectures. Out of the 663 C. difficile genomes, 535 (80.7%) contained at least one copy of ToxA or ToxB, while these genes were missing from 128 genomes. Although some clusters were enriched for toxin presence, these genes are variably present in a given genetic background. The CDT genes were found in 191 genomes, which were restricted to a few clusters only, and only one cluster lacked the toxin A/B genes consistently. A total of 310 genomes contained ToxA/B without CDT (47%). Further, published metagenomic data from stools were used to assess the presence of C. difficile sequences in blinded cases of C. difficile infection (CDI) and controls, to test if metagenomic analysis is sensitive enough to detect the pathogen, and to establish strain relationships between cases from the same

Aristolochic acid nephropathy remains a leading cause of chronic kidney disease (CKD), however few treatment strategies exist. Emerging evidence has shown that H2 relaxin (RLX) possesses powerful antifibrosis and anti-apoptotic properties, therefore we aimed to investigate whether H2 relaxin can be employed to reduce AA-induced cell apoptosis. Human proximal tubular epithelial (HK-2) cells exposed to AA-I were treated with or without administration of H2 RLX. Cell viability was examined using the WST-8 assay. Apoptotic morphologic alterations were observed using the Hoechst 33342 staining method. Apoptosis was detected using flow cytometry. The expression of caspase 3, caspase 8, caspase 9, ERK1/2, Bax, Bcl-2, and Akt proteins was determined by Western blot. Co-treatment with RLX reversed the increased apoptosis observed in the AA-I only treated group. RLX restored expression of phosphorylated Akt which found to be decreased in the AA-I only treated cells. RLX co-treatment led to a decrease in the Bax/Bcl-2 ratio as well as the cleaved form of caspase-3 compared to the AA-I only treated cells. This anti-apoptotic effect of RLX was attenuated by co-administration of the Akt inhibitor LY294002. The present study demonstrated H2 RLX can decrease AA-I induced apoptosis through activation of the PI3K/Akt signaling pathway.

Aristolochic acid (AA), a natural nephrotoxin and carcinogen, can induce a progressive tubulointerstitial nephropathy. However, the mechanism by which AA causes renal injury remains largely unknown. Here we reported that the mitochondrial permeability transition (MPT) plays an important role in the renal injury induced by aristolochic acid I (AAI). We found that in the presence of Ca{sup 2+}, AAI caused mitochondrial swelling, leakage of Ca{sup 2+}, membrane depolarization, and release of cytochrome c in isolated kidney mitochondria. These alterations were suppressed by cyclosporin A (CsA), an agent known to inhibit MPT. Culture of HK-2 cell, a human renal tubular epithelialmore » cell line for 24 h with AAI caused a decrease in cellular ATP, mitochondrial membrane depolarization, cytochrome c release, and increase of caspase 3 activity. These toxic effects of AAI were attenuated by CsA and bongkrekic acid (BA), another specific MPT inhibitor. Furthermore, AAI greatly inhibited the activity of mitochondrial adenine nucleotide translocator (ANT) in isolated mitochondria. We suggested that ANT may mediate, at least in part, the AAI-induced MPT. Taken together, these results suggested that MPT plays a critical role in the pathogenesis of HK-2 cell injury induced by AAI and implied that MPT might contribute to human nephrotoxicity of aristolochic acid.« less

A rapid interference-free spectrofluorometric method combined with the excitation-emission matrix fluorescence and the second-order calibration methods based on the alternating penalty trilinear decomposition (APTLD) and the self-weighted alternating trilinear decomposition (SWATLD) algorithms, was proposed for the simultaneous determination of nephrotoxic aristolochic acid I (AA-I) and aristololactam I (AL-I) in five Chinese herbal medicines. The method was based on a chemical derivatization that converts the non-fluorescent AA-I to high-fluorescent AL-I, achieving a high sensitive and simultaneous quantification of the analytes. The variables of the derivatization reaction that conducted by using zinc powder in acetose methanol aqueous solution, were studied and optimized for best quantification results of AA-I and AL-I. The satisfactory results of AA-I and AL-I for the spiked recovery assay were achieved with average recoveries in the range of 100.4-103.8% and RMSEPs < 0.78 ng mL- 1, which validate the accuracy and reliability of the proposed method. The contents of AA-I and AL-I in five herbal medicines obtained from the proposed method were also in good accordance with those of the validated LC-MS/MS method. In light of high sensitive fluorescence detection, the limits of detection (LODs) of AA-I and AL-I for the proposed method compare favorably with that of the LC-MS/MS method, with the LODs < 0.35 and 0.29 ng mL- 1, respectively. The proposed strategy based on the APTLD and SWATLD algorithms by virtue of the "second-order advantage", can be considered as an attractive and green alternative for the quantification of AA-I and AL-I in complex herbal medicine matrices without any prior separations and clear-up processes.

Aristolochic acid (AA) is a strong cytotoxic nephrotoxin and carcinogen, which induces forestomach and kidney tumors in mice and is associated with development of urothelial cancer in humans. This study sought to gain mechanistic insight into AAI-induced carcinogenesis through analysis of a tumor-relevant endpoint. Female Hupki mice were treated daily with 5 mg AAI/kg body weight by gavage for 3, 12, or 21 days. Histopathology and DNA adduct analysis confirmed kidney and forestomach as target tissues for AAI-induced toxicity. H-ras codon 61 CAA→CTA mutations were measured in mouse kidney and forestomach, as well as liver and glandular stomach (nontarget organs) by allele-specific competitive blocker-PCR (ACB-PCR), because A→T transversion is the predominant mutation induced by AA and this particular mutation was found previously in AA-induced rodent forestomach tumors. Treatment-related differences were observed, with the H-ras mutant fraction (MF) of mouse kidney and forestomach exposed to 5 mg AAI/kg body weight for 21 days significantly higher than that of vehicle-treated controls (Fisher's exact test, P < 0.05). Statistically significant correlations between dA-AAI adduct levels (measured previously in the same animals) and induced H-ras MFs were evident in forestomach of mice treated for 21 days (linear regression, P < 0.05). The significant increase in H-ras MF in kidney and forestomach, along with the correlation between DNA adducts, histopathology, and oncogene mutation, provide definitive evidence that AA induces tumors through a directly mutagenic mode of action. Thus, measurement of tumor-associated mutations is a useful tool for elucidating the mechanisms underlying the tissue specificity of carcinogenesis. Copyright © 2012 Wiley Periodicals, Inc.

Aristolochic acid causes a specific nephropathy (AAN), Balkan endemic nephropathy, and urothelial malignancies. Using Western blotting suitable to determine protein expression, we investigated in several transgenic mouse lines expression of NAD(P)H:quinone oxidoreductase (NQO1)—the most efficient cytosolic enzyme that reductively activates aristolochic acid I (AAI). The mouse tissues used were from previous studies [Arlt et al., Chem. Res. Toxicol. 24 (2011) 1710; Stiborova et al., Toxicol. Sci. 125 (2012) 345], in which the role of microsomal cytochrome P450 (CYP) enzymes in AAI metabolism in vivo had been determined. We found that NQO1 levels in liver, kidney and lung of Cyp1a1(−/−), Cyp1a2(−/−)more » and Cyp1a1/1a2(−/−) knockout mouse lines, as well as in two CYP1A-humanized mouse lines harboring functional human CYP1A1 and CYP1A2 and lacking the mouse Cyp1a1/1a2 orthologs, differed from NQO1 levels in wild-type mice. NQO1 protein and enzymic activity were induced in hepatic and renal cytosolic fractions isolated from AAI-pretreated mice, compared with those in untreated mice. Furthermore, this increase in hepatic NQO1 enzyme activity was associated with bioactivation of AAI and elevated AAI-DNA adduct levels in ex vivo incubations of cytosolic fractions with DNA and AAI. In conclusion, AAI appears to increase its own metabolic activation by inducing NQO1, thereby enhancing its own genotoxic potential. Highlights: ► NAD(P)H:quinone oxidoreductase expression in Cyp1a knockout and humanized CYP1A mice ► Reductive activation of the nephrotoxic and carcinogenic aristolochic acid I (AAI) ► NAD(P)H:quinone oxidoreductase is induced in mice treated with AAI. ► Induced hepatic enzyme activity resulted in elevated AAI-DNA adduct levels.« less

Cell Identity Switching Regulated by Retinoic Acid Signaling Maintains Homogeneous Segments in the Hindbrain.

PubMed

Addison, Megan; Xu, Qiling; Cayuso, Jordi; Wilkinson, David G

2018-06-04

The patterning of tissues to form subdivisions with distinct and homogeneous regional identity is potentially disrupted by cell intermingling. Transplantation studies suggest that homogeneous segmental identity in the hindbrain is maintained by identity switching of cells that intermingle into another segment. We show that switching occurs during normal development and is mediated by feedback between segment identity and the retinoic acid degrading enzymes, cyp26b1 and cyp26c1. egr2, which specifies the segmental identity of rhombomeres r3 and r5, underlies the lower expression level of cyp26b1 and cyp26c1 in r3 and r5 compared with r2, r4, and r6. Consequently, r3 or r5 cells that intermingle into adjacent segments encounter cells with higher cyp26b1/c1 expression, which we find is required for downregulation of egr2b expression. Furthermore, egr2b expression is regulated in r2, r4, and r6 by non-autonomous mechanisms that depend upon the number of neighbors that express egr2b. These findings reveal that a community regulation of retinoid signaling maintains homogeneous segmental identity. Copyright © 2018 The Author(s). Published by Elsevier Inc. All rights reserved.

This report describes an investigation of the pathological mechanism of acute renal failure caused by toxic tubular necrosis after treatment with aristolochic acid I (AAI) in Sprague–Dawley (SD) rats. The rats were gavaged with AAI at 0, 5, 20, or 80 mg/kg/day for 7 days. The pathologic examination of the kidneys showed severe acute tubular degenerative changes primarily affecting the proximal tubules. Supporting these results, we detected significantly increased concentrations of blood urea nitrogen (BUN) and creatinine (Cr) in the rats treated with AAI, indicating damage to the kidneys. Ultrastructural examination showed that proximal tubular mitochondria were extremely enlarged andmore » dysmorphic with loss and disorientation of their cristae. Mitochondrial function analysis revealed that the two indicators for mitochondrial energy metabolism, the respiratory control ratio (RCR) and ATP content, were reduced in a dose-dependent manner after AAI treatment. The RCR in the presence of substrates for complex I was reduced more significantly than in the presence of substrates for complex II. In additional experiments, the activity of respiratory complex I, which is partly encoded by mitochondrial DNA (mtDNA), was more significantly impaired than that of respiratory complex II, which is completely encoded by nuclear DNA (nDNA). A real-time PCR assay revealed a marked reduction of mtDNA in the kidneys treated with AAI. Taken together, these results suggested that mtDNA depletion and respiratory chain defects play critical roles in the pathogenesis of kidney injury induced by AAI, and that the same processes might contribute to aristolochic acid-induced nephrotoxicity in humans. -- Highlights: ► AAI-induced acute renal failure in rats and the proximal tubule was the target. ► Tubular mitochondria were morphologically aberrant in ultrastructural examination. ► AAI impair mitochondrial bioenergetic function and mtDNA replication.« less

The mutagenic activities of aristolochic acid I (AAI) and II (AAII), the two main components of aristolochic acid (AA), were tested for mutagenicity in vivo in a subcutaneous granulation tissue in rats and in vitro in the corresponding freshly isolated and cultured target cells. In vivo at equimolar dose, AAI induced 16 times more 6-thioguanine resistant cells than AAII. Oxygen tension in vitro was adjusted to that found in vivo: in the subcutaneous connective tissue, the pO/sub 2/ was determined to be 40 +/- 9 mm Hg, which corresponds in vitro to an O/sub 2/ concentration of 5% in themore » incubator atmosphere. In vitro, AAI was 19 times more mutagenic than AAII at this low oxygen tension but exhibited only 4 times greater activity than AAII under standard culture conditions. These results indicate that the genotoxic activity of AA in mammals is mainly caused by AAI and that the exposure of cells to AAI and AAII in vitro at low pO/sub 2/ corresponds more closely to the metabolic situation in vivo. Therefore, the mutagenic potency of the two chemicals can only be estimated correctly at tissue oxygen tension. The influence of pO/sub 2/ on the mutation frequencies seems to arise from a modulation of the activation/detoxification pathways.« less

Can an active aging index (AAI) provide insight into reducing elder abuse? A case study in Rajshahi District, Bangladesh.

We use data from respondents aged 60 years and above, collected during April 2009 in the Rajshahi district of Bangladesh, to examine whether high activeness, as captured by an AAI or in sub-domains, can help reduce the risk of elder abuse. The findings suggest that more than half of rural elderly and 14 percent of urban elderly were at some point abused. High activeness in health and security dimensions lowers the risk of being abused while those who are low active in community participation have the lowest risk of being abused in both rural and urban areas. Being literate (elderly with primary/secondary education) is revealed to be a significant factor that lowers the risk of abuse in both rural and urban areas. These results imply a need for educational programs that bolster positive and proper community interaction, in turn promoting a secure later life for elders, and reducing burden for families and society. High activeness in health and security dimensions should also be promoted to keep the elderly healthy and protect from abusive behavior. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

After the incidences of induction of aristolochic acid nephropathy after consumption of herbal weight loss preparations that accidentally contained aristolochic acids (AAs), several countries defined national restrictions on the presence of AAs in food, including plant food supplements (PFS) and herbal products. This study investigates whether the risks associated with exposure to AAs via PFS and herbal products are at present indeed negligible. Data reported in literature on AA levels in PFS and other herbal products and also obtained from a new series of PFS in the present study were used to calculate the estimated daily intakes (EDIs) and corresponding margins of exposure (MOEs). Available literature data revealed that 206 out of 573 samples were found to contain aristolochic acid I (AAI) and/or aristolochic acid II (AAII). The results obtained from recently collected PFS revealed that both AAI and AAII were detected in three out of 18 analysed PFS at levels up to 594.8 and 235.3 µg g -1 , respectively, being in line with the levels reported in literature. The EDIs resulting from intake of these PFS resulted in MOEs that were generally below 10,000, corroborating the priority for risk management. Although these results refer to PFS collected by targeted sampling strategies, the data reveal that AA-containing PFS are still freely available. When considering that the use of these samples may be limited to shorter periods of time, the EDIs might be lower, but MOE values would still be lower than 10,000 for more than 50% of the AA-containing PFS and herbal products. In conclusion, the presence of AAs in PFS and herbal products even several years after instalment of the legal restrictions still raises concern, especially for people who frequently use the respective PFS and herbal products.

Aristolochic acid (AA) is the causative agent of urothelial tumours associated with aristolochic acid nephropathy. These tumours contain TP53 mutations and over-express TP53. We compared transcriptional and translational responses of two isogenic HCT116 cell lines, one expressing TP53 (p53-WT) and the other with this gene knocked out (p53-null), to treatment with aristolochic acid I (AAI) (50-100 {mu}M) for 6-48 h. Modulation of 118 genes was observed in p53-WT cells and 123 genes in p53-null cells. Some genes, including INSIG1, EGR1, CAV1, LCN2 and CCNG1, were differentially expressed in the two cell lines. CDKN1A was selectively up-regulated in p53-WT cells, leadingmore » to accumulation of TP53 and CDKN1A. Apoptotic signalling, measured by caspase-3 and -7 activity, was TP53-dependent. Both cell types accumulated in S phase, suggesting that AAI-DNA adducts interfere with DNA replication, independently of TP53 status. The oncogene MYC, frequently over-expressed in urothelial tumours, was up-regulated by AAI, whereas FOS was down-regulated. Observed modulation of genes involved in endocytosis, e.g. RAB5A, may be relevant to the known inhibition of receptor-mediated endocytosis, an early sign of AA-mediated proximal tubule injury. AAI-DNA adduct formation was significantly greater in p53-WT cells than in p53-null cells. Collectively, phenotypic anchoring of the AAI-induced expression profiles to DNA adduct formation, cell-cycle parameters, TP53 expression and apoptosis identified several genes linked to these biological outcomes, some of which are TP53-dependent. These results strengthen the importance of TP53 in AA-induced cancer, and indicate that other alterations, e.g. to MYC oncogenic pathways, may also contribute.« less

Human liver contains two dihydrodiol dehydrogenases, DD2 and DD4, associated with 3 alpha-hydroxysteroid dehydrogenase activity. We have raised polyclonal antibodies that cross-reacted with the two enzymes and isolated two 1.2 kb cDNA clones (C9 and C11) for the two enzymes from a human liver cDNA library using the antibodies. The clones of C9 and C11 contained coding sequences corresponding to 306 and 321 amino acid residues respectively, but lacked 5'-coding regions around the initiation codon. Sequence analyses of several peptides obtained by enzymic and chemical cleavages of the two purified enzymes verified that the C9 and C11 clones encoded DD2 and DD4 respectively, and further indicated that the sequence of DD2 had at least additional 16 residues upward from the N-terminal sequence deduced from the cDNA. There was 82% amino acid sequence identity between the two enzymes, indicating that the enzymes are genetic isoenzymes. A computer-based comparison of the cDNAs of the isoenzymes with the DNA sequence database revealed that the nucleotide and amino acid sequences of DD2 and DD4 are virtually identical with those of human bile-acid binder and human chlordecone reductase cDNAs respectively.

Nucleic-acid approaches to characterizing naturally occurring microorganisms in their habitats have risen to prominence during the last decade. Extraction of deoxyribonucleic-acid (DNA) and ribonucleic-acid (RNA) biomarkers directly from environmental samples provides a new means of gathering information in microbial ecology. This review article defines: (1) the subsurface habitat; (2) what nucleic-acid procedures are; and (3) the types of information nucleic-acid procedures can and cannot reveal. Recent literature examining microbial nucleic acids in the terrestrial subsurface is tabulated and reviewed. The majority of effort to date has focused upon insights into the identity and phylogeny of subsurface microorganisms afforded by analysis of their 16S rRNA genes. Given the power of nucleic-acid-based procedures and their limited application to subsurface habitats to date, many future opportunities await exploration. Au cours des derniers dix ans, les approches basées sur les acides nucléiques sont apparues et devenues essentielles pour caractériser dans leurs habitats les microorganismes existant à l'état naturel. L'extraction directe de l'ADN et de l'ARN, qui sont des biomarqueurs, d'échantillons environnementaux a fourni un nouveau moyen d'obtenir des informations sur l'écologie microbienne. Cet article synthétique définit 1) l'habitat souterrain, 2) ce que sont les procédures basées sur les acides nucléiques, 3) quel type d'informations ces procéedures peuvent et ne peuvent pas révéler.

La majorité des efforts pour obtenir es données s'est concentrée sur l'identité et la phylogénie des microorganismes souterrains fournies par l'analyse de leurs gènes 16S rRNA.

Microbial genomic taxonomy

PubMed Central

2013-01-01

A need for a genomic species definition is emerging from several independent studies worldwide. In this commentary paper, we discuss recent studies on the genomic taxonomy of diverse microbial groups and a unified species definition based on genomics. Accordingly, strains from the same microbial species share >95% Average Amino Acid Identity (AAI) and Average Nucleotide Identity (ANI), >95% identity based on multiple alignment genes, <10 in Karlin genomic signature, and > 70% in silico Genome-to-Genome Hybridization similarity (GGDH). Species of the same genus will form monophyletic groups on the basis of 16S rRNA gene sequences, Multilocus Sequence Analysis (MLSA) and supertree analysis. In addition to the established requirements for species descriptions, we propose that new taxa descriptions should also include at least a draft genome sequence of the type strain in order to obtain a clear outlook on the genomic landscape of the novel microbe. The application of the new genomic species definition put forward here will allow researchers to use genome sequences to define simultaneously coherent phenotypic and genomic groups. PMID:24365132

A bacterial strain isolated from a food processing drainage system in Costa Rica fulfilled the criteria as belonging to the genus Listeria, but could not be assigned to any of the known species. Phylogenetic analysis based on the 16S rRNA gene revealed highest sequence similarity with the type strain of Listeria floridensis (98.7 %). Phylogenetic analysis based on Listeria core genomes placed the novel taxon within the Listeria fleishmannii, L. floridensis and Listeria aquatica clade (Listeria sensu lato). Whole-genome sequence analyses based on the average nucleotide blast identity (ANI<80 %) indicated that this isolate belonged to a novel species. Results of pairwise amino acid identity (AAI>70 %) and percentage of conserved proteins (POCP>68 %) with currently known Listeria species, as well as of biochemical characterization, confirmed that the strain constituted a novel species within the genus Listeria. The name Listeria costaricensis sp. nov. is proposed for the novel species, and is represented by the type strain CLIP 2016/00682 T (=CIP 111400 T =DSM 105474 T ).

Aristolochic acids (AAs) widely exist in such plants as Aristolochia and Asarum. The renal toxicity of AAs as well as its carcinogenicity to urinary system have been widely known. In 2003 and 2004, China prohibited the use of Aristolochiae Radix, Aristolochiae Manshuriensis Caulis and Aristolochiae Fangchi Radix, and required administering other AAs-containing medicines in accordance with the regulations for prescription drugs. In this paper, we retrieved literatures on the content determination of AAs in recent 10 years in China. It suggested that the AAs content is lower in Asarum herb, especially in its roots and rhizomes, and most of which do not show detectable amount of AA-I. Some of traditional Chinese medicines show fairly small amount of detectable AA-I. The AAs content in Aristolochia herb (including Fructus Aristolochiae, kaempfer dutchmanspipe root) is relatively high; however, there are fewer literatures for studying the content determination of AAs in Chinese patent medicines. There were many factors affecting AAs content, including the parts used, origins, processing methods, extraction process. It suggested that we should pay attention to the toxicity of Chinese medicines containing AAs and use these decoction pieces and traditional Chinese medicines cautiously. In addition, basic studies for the origins, processing methods and extraction process of Chinese patent medicines containing AAs, as well as supervision and detection of AAs content in traditional Chinese medicinal materials, decoction pieces and Chinese patent medicines shall be strengthened for reducing medication risk and guaranteeing clinical medication safety.

Applying One Health to the Study of Animal-Assisted Interventions.

PubMed

Chalmers, Darlene; Dell, Colleen Anne

2015-12-01

The use of animal-assisted interventions in therapeutic programs is a growing phenomenon. Animal-assisted interventions (AAIs) involve a variety of species (dogs, cats, horses, domesticated birds, etc.) in primary health care. Despite their increasing application in a wide range of therapeutic services, the empirical evidence base of AAIs is limited. The authors of this paper propose that the public health framework of One Health can be adapted to advance AAI research. One Health's perspective on the environment is primarily ecological. The environmental impact on the human-animal interactions within AAIs, however, incorporates social, cultural, political, and economic factors. The environment has received minimal attention in AAI research. The authors discuss how this framework has been used in their prior AAI research and work with Indigenous people. Applying this framework to AAIs may guide future AAI research.

Background The evolution of the full repertoire of proteins encoded in a given genome is mostly driven by gene duplications, deletions, and sequence modifications of existing proteins. Indirect information about relative rates and other intrinsic parameters of these three basic processes is contained in the proteome-wide distribution of sequence identities of pairs of paralogous proteins. Results We introduce a simple mathematical framework based on a stochastic birth-and-death model that allows one to extract some of this information and apply it to the set of all pairs of paralogous proteins in H. pylori, E. coli, S. cerevisiae, C. elegans, D. melanogaster, and H. sapiens. It was found that the histogram of sequence identities p generated by an all-to-all alignment of all protein sequences encoded in a genome is well fitted with a power-law form ~ p-γ with the value of the exponent γ around 4 for the majority of organisms used in this study. This implies that the intra-protein variability of substitution rates is best described by the Gamma-distribution with the exponent α ≈ 0.33. Different features of the shape of such histograms allow us to quantify the ratio between the genome-wide average deletion/duplication rates and the amino-acid substitution rate. Conclusion We separately measure the short-term ("raw") duplication and deletion rates rdup∗, rdel∗ which include gene copies that will be removed soon after the duplication event and their dramatically reduced long-term counterparts rdup, rdel. High deletion rate among recently duplicated proteins is consistent with a scenario in which they didn't have enough time to significantly change their functional roles and thus are to a large degree disposable. Systematic trends of each of the four duplication/deletion rates with the total number of genes in the genome were analyzed. All but the deletion rate of recent duplicates rdel∗ were shown to systematically increase with Ngenes. Abnormally flat shapes

An endogenous factor enhances ferulic acid decarboxylation catalyzed by phenolic acid decarboxylase from Candida guilliermondii

PubMed Central

2012-01-01

The gene for a eukaryotic phenolic acid decarboxylase of Candida guilliermondii was cloned, sequenced, and expressed in Escherichia coli for the first time. The structural gene contained an open reading frame of 504 bp, corresponding to 168 amino acids with a calculated molecular mass of 19,828 Da. The deduced amino sequence exhibited low similarity to those of functional phenolic acid decarboxylases previously reported from bacteria with 25-39% identity and to those of PAD1 and FDC1 proteins from Saccharomyces cerevisiae with less than 14% identity. The C. guilliermondii phenolic acid decarboxylase converted the main substrates ferulic acid and p-coumaric acid to the respective corresponding products. Surprisingly, the ultrafiltrate (Mr 10,000-cut-off) of the cell-free extract of C. guilliermondii remarkably activated the ferulic acid decarboxylation by the purified enzyme, whereas it was almost without effect on the p-coumaric acid decarboxylation. Gel-filtration chromatography of the ultrafiltrate suggested that an endogenous amino thiol-like compound with a molecular weight greater than Mr 1,400 was responsible for the activation.

The spectroscopic discrimination of the two structurally similar polyunsaturated C 20 fatty acids (PUFAs) 5,8,11,14,17-eicosapentaenoic acid and 5,8,11,14-eicosatetraenoic acid (arachidonic acid) is shown. For this purpose their vibrational structures are studied by means of attenuated total reflection (ATR) Fourier-transform infrared (FT-IR) spectroscopy. The fingerprint regions of the recorded spectra are found to be almost identical, while the C-H stretching mode regions around 3000 cm -1 show such significant differences as results of electronic and molecular structure alterations based on the different degree of saturation that both fatty acids can be clearly distinguished from each other.

We used morphological and molecular data to infer the identity and origin of frogs in the genus Fejervarya that have been introduced to the island of Guam. Mensural and meristic data were collected from 96 specimens from throughout their range on the island and a principal component analysis was used to investigate the distribution of these data in morphological space. We also amplified a fragment of the 16S ribosomal ribonucleic acid mitochondrial gene from 27 of these specimens and compared it to 63 published sequences of Fejervarya and the morphologically similar Zakerana. All examined Fejervarya from Guam are morphologically indistinguishable and share an identical haplotype. The molecular data identify them as Fejervarya cancrivora with a haplotype identical to F. cancrivora from Taiwan.

Detection of asymptomatic peripheral arterial disease increases the risk of vascular morbibity and mortality. We aimed to estimate the prevalence of clinical and subclinical peripheral arterial disease using the ankle-arm index (AAI) as diagnostic tool in a working population. We included 450 workers, older than 50 years old, attending voluntary regular health check-up at Centro de Prevención de Riesgos Laborales de la Junta de Andalucía in Málaga (Spain). We recorded clinical and anthopometrical data. Blood samples were taken after an overnight fast. Vascular risk was calculated using Framinghan and SCORE scales. Every participant was asked for symptoms of intermittent claudicatio and AAI was measured. AAI was considered normal within 0.9-1.3 values. Most of our workers were at low- or moderate vascular risk. Only 48 (10.6%) of individuals had an abnormal AAI: 9 (2%) showed an AAI<0.9 and 39 (8.6%) showed an AAI>1.3. An AAI<0.9 was found in 19% of those with a SCORE risk > or = 5%, and in 11% of those having a Framinghan risk > or = 20%. Intermittent claudication was present in 4 out of 9 (44%) of those having an AAI<0.9 and in 7 out of 402 (1.7%) with a normal AAI. Systematic screening of peripheral arterial disease using the AAI is not recommended in active working population over 50 years-old of age. Thus, AAI measurement is indicated only for those individuals suffering from intermitent claudicatio and those who are at moderate- or high vascular risk.

Background Vibrio taxonomy has been based on a polyphasic approach. In this study, we retrieve useful taxonomic information (i.e. data that can be used to distinguish different taxonomic levels, such as species and genera) from 32 genome sequences of different vibrio species. We use a variety of tools to explore the taxonomic relationship between the sequenced genomes, including Multilocus Sequence Analysis (MLSA), supertrees, Average Amino Acid Identity (AAI), genomic signatures, and Genome BLAST atlases. Our aim is to analyse the usefulness of these tools for species identification in vibrios. Results We have generated four new genome sequences of three Vibrio species, i.e., V. alginolyticus 40B, V. harveyi-like 1DA3, and V. mimicus strains VM573 and VM603, and present a broad analyses of these genomes along with other sequenced Vibrio species. The genome atlas and pangenome plots provide a tantalizing image of the genomic differences that occur between closely related sister species, e.g. V. cholerae and V. mimicus. The vibrio pangenome contains around 26504 genes. The V. cholerae core genome and pangenome consist of 1520 and 6923 genes, respectively. Pangenomes might allow different strains of V. cholerae to occupy different niches. MLSA and supertree analyses resulted in a similar phylogenetic picture, with a clear distinction of four groups (Vibrio core group, V. cholerae-V. mimicus, Aliivibrio spp., and Photobacterium spp.). A Vibrio species is defined as a group of strains that share > 95% DNA identity in MLSA and supertree analysis, > 96% AAI, ≤ 10 genome signature dissimilarity, and > 61% proteome identity. Strains of the same species and species of the same genus will form monophyletic groups on the basis of MLSA and supertree. Conclusion The combination of different analytical and bioinformatics tools will enable the most accurate species identification through genomic computational analysis. This endeavour will culminate in the birth of the online

Determination of aristolochic acids by high-performance liquid chromatography with fluorescence detection.

Nephrotoxic and carcinogenic aristolochic acids (AAs) are naturally occurring nitrophenanthrene carboxylic acids in the herbal genus Aristolochia. The misuse of AA-containing herbs in preparing slimming drugs has caused hundred of cases of kidney disease in Belgium women in a slimming regime in the early 1990s. Accumulating evidence also suggested that prolong dietary intake of AA-contaminated food is one of the major causes to the Balkan endemic nephropathy that was first observed in the late 1950s. Therefore, analytical methods of high sensitivity are extremely important for safeguarding human exposure to AA-containing herbal medicines, herbal remedies, and food composites. In this paper, we describe the development of a new high-performance liquid chromatography coupled fluorescence detector (HPLC-FLD) method for the sensitive determination of AAs. The method makes use of a novel cysteine-induced denitration reaction that "turns on" the fluorescence of AAs for fluorometric detections. Our results showed that the combination of cysteine-induced denitration and HPLC-FLD analysis allows for sensitive quantification of AA-I and AA-II at detection limits of 27.1 and 25.4 ng/g, respectively. The method was validated and has been successfully applied in quantifying AAs in Chinese herbal medicines.

Constructing nurses' professional identity through social identity theory.

Willetts, Georgina; Clarke, David

2014-04-01

The profession of nursing continues to struggle with defining and clarifying its professional identity. The definitive recognition of nursing as a profession was the moving of training from the hospital apprentice model to the tertiary sector. However, this is only part of the story of professional identity in nursing. Once training finishes and enculturation into the workplace commences, professional identity becomes a complicated social activity. This paper proposes social identity theory as a valuable research framework to assist with clarifying and describing the professional identity of nurses. The paper outlines the key elements of a profession and then goes on to describe the main concepts of social identity theory. Lastly, a connection is made between the usefulness of using social identity theory in researching professional identity in nursing, recognizing the contextual nature of the social activity of the profession within its workplace environment. © 2013 Wiley Publishing Asia Pty Ltd.

Resolving an identity crisis: Implicit drinking identity and implicit alcohol identity are related but not the same.

2017-09-01

Two variations of the Implicit Association Test (IAT), the Drinking Identity IAT and the Alcohol Identity IAT, assess implicit associations held in memory between one's identity and alcohol-related constructs. Both have been shown to predict numerous drinking outcomes, but these IATs have never been directly compared to one another. The purpose of this study was to compare these IATs and evaluate their incremental predictive validity. US undergraduate students (N=64, 50% female, mean age=21.98years) completed the Drinking Identity IAT, the Alcohol Identity IAT, an explicit measure of drinking identity, as well as measures of typical alcohol consumption and hazardous drinking. When evaluated in separate regression models that controlled for explicit drinking identity, results indicated that the Drinking Identity IAT and the Alcohol Identity IAT were significant, positive predictors of typical alcohol consumption, and that the Drinking Identity IAT, but not the Alcohol Identity IAT, was a significant predictor of hazardous drinking. When evaluated in the same regression models, the Drinking Identity IAT, but not the Alcohol Identity IAT, was significantly associated with typical and hazardous drinking. These results suggest that the Drinking Identity IAT and Alcohol Identity IAT are related but not redundant. Moreover, given that the Drinking Identity IAT, but not the Alcohol Identity IAT, incrementally predicted variance in drinking outcomes, identification with drinking behavior and social groups, as opposed to identification with alcohol itself, may be an especially strong predictor of drinking outcomes.

Modern women's identity crises and the various possibilities of identification along the way towards a new identity can be seen as her attempts to develop out of the depressive situation that her once normal role identity had, to a large extent, placed her in. Under this aspect, even concepts of living that are seen by many to be problematic can be justified as leading along the way towards identity, which is so essential for human relationships and interpersonal empathy.

Nicotinic Acid Metabolism, V. A Cobamide Coenzyme-Dependent Conversion of α-Methyleneglutaric Acid to Dimethylmaleic Acid

A new B12-coenzyme-dependent isomerization, catalyzed by extracts of a nicotinate-fermenting clostridium, results in the conversion of α-methyleneglutaric acid to dimethylmaleic acid. These two acids are intermediates in the multistep anaerobic process wherein nicotinate is converted, ultimately, to one mole each of propionate, acetate, carbon dioxide, and ammonia. Dimethylmaleic acid reacts in its anhydride form with 2,4-dinitrophenylhydrazine to form N-2′,4′-dinitrophenyl-anilino-3,4-dimethylmaleimide. The characteristic reddish color exhibited by the latter derivative in alkaline solution serves as a convenient quantitative assay for dimethylmaleic acid. Comparison of the 2,4-dinitrophenylhydrazine derivatives of the product of the enzymic reaction and of synthetic dimethylmaleic anhydride showed them to be identical in every respect. PMID:5266166

This study was designed to assess the peak force of a manually operated chiropractic adjusting instrument, the Activator Adjusting Instrument 4 (AAI 4), with an adapter for use in animals, which has a 3- to 4-fold smaller contact surface area than the original rubber tip. Peak force was determined by thrusting the AAI 4 with the adapter or the original rubber tip onto a load cell. First, the AAI 4 was applied perpendicularly by a doctor of chiropractic onto the load cell. Then, the AAI 4 was fixed in a rigid framework and applied to the load cell. This procedure was done to prevent any load on the load cell before the thrust impulse. In 2 situations, trials were performed with the AAI 4 at all force settings (settings I, II, III, and IV, minimum to maximum, respectively). A total of 50000 samples per second over a period of 3 seconds were collected. In 2 experimental protocols, the use of the adapter in the AAI 4 increased the peak force only with setting I. The new value was around 80% of the maximum value found for the AAI 4. Nevertheless, the peak force values of the AAI 4 with the adapter and with the original rubber tip in setting IV were similar. The adapter effectively determines the maximum peak force value at force setting I of AAI 4. Copyright © 2014 National University of Health Sciences. Published by Mosby, Inc. All rights reserved.

Implication of the cause of differences in 3D structures of proteins with high sequence identity based on analyses of amino acid sequences and 3D structures.

Proteins that share a high sequence homology while exhibiting drastically different 3D structures are investigated in this study. Recently, artificial proteins related to the sequences of the GA and IgG binding GB domains of human serum albumin have been designed. These artificial proteins, referred to as GA and GB, share 98% amino acid sequence identity but exhibit different 3D structures, namely, a 3α bundle versus a 4β + α structure. Discriminating between their 3D structures based on their amino acid sequences is a very difficult problem. In the present work, in addition to using bioinformatics techniques, an analysis based on inter-residue average distance statistics is used to address this problem. It was hard to distinguish which structure a given sequence would take only with the results of ordinary analyses like BLAST and conservation analyses. However, in addition to these analyses, with the analysis based on the inter-residue average distance statistics and our sequence tendency analysis, we could infer which part would play an important role in its structural formation. The results suggest possible determinants of the different 3D structures for sequences with high sequence identity. The possibility of discriminating between the 3D structures based on the given sequences is also discussed.

A fatty acid binding protein (FABP) as been identified and characterized in rat heart, but the function and regulation of this protein are unclear. In this study the cDNA for rat heart FABP was cloned from a lambda gt11 library. Sequencing of the cDNA showed an open reading frame coding for a protein with 133 amino acids and a calculated size of 14,776 daltons. Several differences were found between the sequence determined from the cDNA and that reported previously by protein sequencing techniques. Northern blot analysis using rat heart FABP cDNA as a probe established the presence of an abundantmore » mRNA in rat heart about 0.85 kilobases in length. This mRNA was detected, but was not abundant, in fetal heart tissue. Tissue distribution studies showed a similar mRNA species in red, but not white, skeletal muscle. In general, the mRNA tissue distribution was similar to that of the protein detected by Western immunoblot analysis, suggesting that heart FABP expression may be regulated at the transcriptional level. S1 nuclease mapping studies confirmed that the mRNA hybridized to rat heart FABP cDNA was identical in heart and red skeletal muscle throughout the entire open reading frame. The structural differences between heart FABP and other members of this multigene family may be related to the functional requirements of oxidative muscle for fatty acids as a fuel source.« less

Social identity change: shifts in social identity during adolescence.

2011-06-01

This study investigated the proposition that adolescence involves significant shifts in social identity as a function of changes in social context and cognitive style. Using an experimental design, we primed either peer or gender identity with a sample of 380 early- (12-13 years), mid- (15-16 years), and late-adolescents (18-20 years) and then measured the effect of the prime on self-stereotyping and ingroup favouritism. The findings showed significant differences in social identity across adolescent groups, in that social identity effects were relatively strong in early- and late-adolescents, particularly when peer group identity rather than gender identity was salient. While these effects were consistent with the experience of change in educational social context, differences in cognitive style were only weakly related to ingroup favouritism. The implications of the findings for theory and future research on social identity during adolescence are discussed. Crown Copyright © 2010. Published by Elsevier Ltd. All rights reserved.

The study examined: (1) the intergenerational concordance between parents and their adolescent sons using the Adult Attachment Interview (AAI) categories and state-of-mind scales; and (2) the contribution of parents' state of mind with respect to attachment to their sons' adjustment during a stressful separation, as well as the possibility that sons' AAI mediates the associations between parents' AAI and sons' adjustment. Eighty-eight adolescents and their parents were interviewed using the AAI during the son's senior year in high school. Approximately a year later, during the first phase of compulsory military service, the adolescents and their peers reported on the sons' adjustment. Results demonstrated AAI correspondence between mothers' (but not fathers) and sons' categories (autonomous versus non-autonomous) and associations between mothers', fathers' and sons' AAI state-of-mind scales. The adjustment of sons of non-autonomous mothers (in particular, preoccupied mothers) was inferior to the adjustment of others. Mothers' and fathers' state of mind scales were associated with sons' adjustment, but sons' AAI did not mediate this association. The uniqueness of adolescence, the importance of parents' state of mind and the differences between mothers and fathers are discussed.

Comparative Associations Between Achieved Bicultural Identity, Achieved Ego Identity, and Achieved Religious Identity and Adaptation Among Australian Adolescent Muslims.

This study examined the comparative roles of biculturalism, ego identity, and religious identity in the adaptation of Australian adolescent Muslims. A total of 504 high school Muslim students studying at high schools in metropolitan Sydney and Melbourne, Australia, took part in this study which required them to complete a self-report questionnaire. Analyses indicated that adolescent Muslims' achieved religious identity seems to play a more important role in shaping their psychological and socio-cultural adaptation compared to adolescents' achieved bicultural identity. Adolescents' achieved ego identity tended also to play a greater role in their psychological and socio-cultural adaptation than achieved bicultural identity. The relationships between the three identities and negative indicators of psychological adaptation were consistently indifferent. Based on these findings, we propose that the three identity-based forces-bicultural identity development, religious identity attainment, and ego identity formation-be amalgamated into one framework in order for researchers to more accurately examine the adaptation of Australian adolescent Muslims.

Swiss identity smells like chocolate: Social identity shapes olfactory judgments

There is extensive evidence that social identities can shape people’s attitudes and behavior, but what about sensory judgments? We examined the possibility that social identity concerns may also shape the judgment of non-social properties—namely, olfactory judgment. In two experiments, we presented Swiss and non-Swiss participants with the odor of chocolate, for which Switzerland is world-famous, and a control odor (popcorn). Swiss participants primed with Swiss identity reported the odor of chocolate (but not popcorn) as more intense than non-Swiss participants (Experiments 1 and 2) and than Swiss participants primed with individual identity or not primed (Experiment 2). The self-reported intensity of chocolate smell tended to increase as identity accessibility increased—but only among Swiss participants (Experiment 1). These results suggest that identity priming can counter-act classic sensory habituation effects, allowing identity-relevant smells to maintain their intensity after repeated presentations. This suggests that social identity dynamically influences sensory judgment. We discuss the potential implications for models of social identity and chemosensory perception. PMID:27725715

Tentative evidence is presented for the presence of N-methylalanine, N-ethylglycine, β-aminoisobutyric acid, and norvaline. These amino acids appear to be extraterrestrial in origin and may provide new evidence for the hypothesis of chemical evolution. PMID:16591908

2009-10-01

Volatile and semi-volatile secondary metabolites, as well as aristolochic acids (AA), present in leaves, stems, and flowers of Aristolochia ringens were determined by gas chromatography (GC)-mass spectrometry (MS) and high-performance liquid chromatography (HPLC) methods, respectively. Metabolite isolation was performed using different extraction techniques: microwave-assisted hydrodistillation (MWHD), supercritical fluid extraction, and headspace solid-phase microextraction (HS-SPME). The chemical composition of the extracts and oils was established by GC-MS. The determinations of AAI and AAII were conducted by methanolic extraction of different plant parts followed by HPLC analysis. Essential oil yields from leaves and stems were 0.008 +/- 0.0022% and 0.047 +/- 0.0026%, respectively. Aristolochia ringens flowers did not yield essential oil under MWHD. Sesquiterpene hydrocarbons (66%) were the main compounds in the essential oil isolated from leaves whereas monoterpene hydrocarbons (73%) predominated in the stems essential oil. Yields of extracts isolated by SFE from leaves, stems, and flowers were 4 +/- 1.8%, 1.2 +/- 0.25%, and 4 +/- 1.8%, respectively. In vivo HS-SPME of flowers isolated compounds with known unpleasant smells such as volatile aldehydes and short-chain carboxylic acids. HPLC analysis detected the presence of AAII in the flowers of Aristolochia ringens at a concentration of 610 +/- 47 mg/kg of dried flower.

Adrenaline auto-injectors (AAI) should be provided to individuals considered to be at high risk of anaphylaxis. There is some evidence that the rate of AAI prescription is increasing, but the true extent has not been previously quantified. To estimate the trends in annual GP-issued prescriptions for AAI among UK children between 2000 and 2012. Retrospective cohort study using data from primary care practices that contributed to The Health Improvement Network (THIN) database. Children and young people aged between 0-17 years of age with a prescription for AAIs were identified, and annual AAI device prescription rates were estimated using Stata (version 12). A total of 1.06 million UK children were identified, providing 5.1 million person years of follow-up data. Overall, 23 837 children were deemed high risk by their GPs, and were prescribed 98 737 AAI devices. This equates to 4.67 children (95% confidence interval [CI] = 4.66 to 4.69), and 19.4 (95% CI = 19.2 to 19.5) devices per 1000 person years. Between 2000 and 2012, there has been a 355% increase in the number of children prescribed devices, and a 506% increase in the total number of AAI devices prescribed per 1000 person years in the UK. The number of devices issued per high-risk child during this period has also increased by 33%. The number of children being prescribed AAI devices and the number of devices being prescribed in UK primary care between 2000 and 2012 has significantly increased. A discussion to promote rational prescribing of AAIs in the NHS is needed. © British Journal of General Practice 2017.

Purpose The optimal pacing mode with either single chamber atrial pacemaker (AAI or AAIR) or dual chamber pacemaker (DDD or DDDR) is still not clear in sinus-node dysfunction (SND) and intact atrioventricular (AV) conduction. Materials and Methods Patients who were implanted with permanent pacemaker using AAI(R) (n = 73) or DDD(R) (n = 113) were compared. Results The baseline characteristics were comparable between the two groups, with a mean follow-up duration of 69 months. The incidence of death did not show statistical difference. However, the incidence of hospitalization for congestive heart failure (CHF) was significantly lower in the AAI(R) group (0%) than the DDD(R) group (8.8%, p = 0.03). Also, atrial fibrillation (AF) was found in 2.8% in the AAI(R) group, which was statistically different from 15.2% of patients in the DDD(R) group (p = 0.01). Four patients (5.5%) with AAI(R) developed AV block, and subsequently switched to DDD(R) pacing. The risk of AF was lower in the patients implanted with AAI(R) than those with DDD(R) [hazard ratio (HR), 0.84; 95% confidence interval, 0.72 to 0.97, p = 0.02]. Conclusion In patients with SND and intact AV conduction, AAI(R) pacing can achieve a better clinical outcome in terms of occurrence of CHF and AF than DDD(R) pacing. These findings support AAI(R) pacing as the preferred pacing mode in patients with SND and intact AV conduction. PMID:20879047

1987-07-01

To assess the effectiveness of child-resistant closures (CRCs) and unit dose packaging in preventing childhood poisoning with medications, a survey by 14 hospitals of accidental suspected poisoning in children under 5-years-old, was compared with a survey of a representative sample of households with children under 5 living in the catchment areas of the hospitals. Nine hundred and thirty-eight medications thought to have been ingested by 877 children were compared with 5827 medications found in households with children. The relationship between availability of packs or medications in the home and their involvement in accidents was quantified by means of an Accident Association Index (AAI). A low AAI indicated that the involvement of a pack or medication was less than expected from availability and therefore safe. A high AAI indicated that involvement was greater than expected and therefore unsafe. Medications involved in suspected poisoning were most frequently packed in containers without CRCs (63%) or transparent blisters (20%); both had high AAIs. CRCs, strips, sachets and opaque blisters had low AAIs. Analgesics, expectorants and gastrointestinal medications, had low AAIs, while oral contraceptives, hypnotics, sedative/tranquillizers, antidepressants, anticonvulsants, anti-emetics, and anti-infectives had high AAIs. Prescription medications were more frequently involved in accidents than over-the-counter (OTC) medications and had a higher AAI. Comparison of the AAIs of different kinds of medication in each of their various pack types showed that safe packaging reduced the risk from medications which had a high average AAI. Only 40% of medications were in their normal storage place at the time of the accident. Medicine and bathroom cabinets, and kitchen cupboards and drawers were the safest places to store medications. Handbags, fridges, and shelves or ledges in the bathroom were the most unsafe places. No pack had a low AAI when stored on open shelves

Mistaken identity: activating conservative political identities induces "conservative" financial decisions.

PubMed

Morris, Michael W; Carranza, Erica; Fox, Craig R

2008-11-01

Four studies investigated whether activating a social identity can lead group members to choose options that are labeled in words associated with that identity. When political identities were made salient, Republicans (but not Democrats) became more likely to choose the gamble or investment option labeled "conservative." This shift did not occur in a condition in which the same options were unlabeled. Thus, the mechanism underlying the effect appears to be not activated identity-related values prioritizing low risk, but rather activated identity-related language (the group label "conservative"). Indeed, when political identities were salient, Republicans favored options labeled "conservative" regardless of whether the options were low or high risk. Finally, requiring participants to explain the label "conservative" before making their choice did not diminish the effect, which suggests that it does not merely reflect inattention to content or construct accessibility. We discuss the implications of these results for the literatures on identity, priming, choice, politics, and marketing.

Change in heart rate variability after the adult attachment interview in dissociative patients.

2015-01-01

The aim of this study was to assess heart rate variability (HRV) in individuals with dissociative disorders (DD) before and after the Adult Attachment Interview (AAI). Electrocardiograms were recorded before, during, and after the AAI in 13 individuals with DD and 13 healthy participants matched for age and gender. Significant change in HRV was observed only in the DD group. After the AAI, those with DD showed significant increases in the low frequency/high frequency ratio (pre-AAI = 1.91 ± 1.19; post-AAI = 4.03 ± 2.40; Wilcoxon test = -2.76, p = .005). Our results suggest that the retrieval of childhood attachment experiences in individuals with DD is associated with a change in HRV patterns that could reflect the emotion dysregulation of dissociative psychopathological processes.

Envenomation by poisons of biological origin is very common globally in the tropical and subtropical areas mainly, where the biological diversity of the species clearly leads to evolution of highly toxic species. The weather warming trend in Bulgaria, whether cyclic or permanent, allows for a change in the biological response of reptiles and insects inhabiting the temperate zone by a possible migration of biological species from the subtropical zone towards the temperate zone because of the new environmental conditions. There are very few studies on snake bite envenoming in Bulgaria. The AIM of the study was to find the incidence of the acute accidental intoxication (AAI) caused by snake venom in adult individuals in a large region of Bulgaria between 2004 and 2012 and characterises it by number, type, main clinical features, course and socio-demographic parameters of the victims so that preventive measures can be taken, wherever necessary. We studied retrospectively all 68 cases of AAI caused by snake venom in adult individuals (> 18 years old) hospitalized in the Clinic of Toxicology in St. George University Hospital, Plovdiv over the period from 2004 to 2012 by 23 quantitative and qualitative parameters. We found that the average annual incidence of snake venom AAI in adult population in the region of Plovdiv was relatively low for the specified period (9.5 per 100000 residents); the snake venom AAI increases or decreases every other year, with no clearly delineated trend for now. The prevalence of envenomation by poisons of biological origin increased from 2.3% in 1990-1998 to 9.5-10.33% between 2007 and 2012. The main sociodemographic characteristics of snake bite victims are similar to those in other Balkan and Central European countries. The clinical response to poisons of biological origin is generally identical with the response to the viper (Vipera ammodytes)--mild to medium intensity with predominantly local toxic syndrome.

Yip, Tiffany

2013-01-01

The current study explores the intersection of ethnic identity development and significance in a sample of 354 diverse adolescents (mean age 14). Adolescents completed surveys 5 times a day for 1 week. Cluster analyses revealed 4 identity clusters: diffused, foreclosed, moratorium, achieved. Achieved adolescents reported the highest levels of identity salience across situations, followed by moratorium adolescents. Achieved and moratorium adolescents also reported a positive association between identity salience and private regard. For foreclosed and achieved adolescents reporting low levels of centrality, identity salience was associated with lower private regard. For foreclosed and achieved adolescents reporting high levels of centrality, identity salience was associated with higher private regard. PMID:23581701

A Dual Identity Approach for Conceptualizing and Measuring Children's Gender Identity.

PubMed

Martin, Carol Lynn; Andrews, Naomi C Z; England, Dawn E; Zosuls, Kristina; Ruble, Diane N

2017-01-01

The goal was to test a new dual identity perspective on gender identity by asking children (n = 467) in three grades (M age  = 5.7, 7.6, 9.5) to consider the relation of the self to both boys and girls. This change shifted the conceptualization of gender identity from one to two dimensions, provided insights into the meaning and measurement of gender identity, and allowed for revisiting ideas about the roles of gender identity in adjustment. Using a graphical measure to allow assessment of identity in young children and cluster analyses to determine types of identity, it was found that individual and developmental differences in how similar children feel to both genders, and these variations matter for many important personal and social outcomes. © 2016 The Authors.

The Identity Mapping Project: Demographic differences in patterns of distributed identity.

Gilbert, Richard L; Dionisio, John David N; Forney, Andrew; Dorin, Philip

2015-01-01

The advent of cloud computing and a multi-platform digital environment is giving rise to a new phase of human identity called "The Distributed Self." In this conception, aspects of the self are distributed into a variety of 2D and 3D digital personas with the capacity to reflect any number of combinations of now malleable personality traits. In this way, the source of human identity remains internal and embodied, but the expression or enactment of the self becomes increasingly external, disembodied, and distributed on demand. The Identity Mapping Project (IMP) is an interdisciplinary collaboration between psychology and computer Science designed to empirically investigate the development of distributed forms of identity. Methodologically, it collects a large database of "identity maps" - computerized graphical representations of how active someone is online and how their identity is expressed and distributed across 7 core digital domains: email, blogs/personal websites, social networks, online forums, online dating sites, character based digital games, and virtual worlds. The current paper reports on gender and age differences in online identity based on an initial database of distributed identity profiles.

2017-08-01

The present study had a dual purpose: to obtain a comprehensive picture of the Italian medical practitioners' opinions, professional experiences, training needs and knowledge of Animal Assisted Interventions (AAI); and to provide a detailed description of the medical practitioners who are characterized by a strongly positive attitude towards AAI. An online survey addressed to Italian medical practitioners was carried out using a 35-items structured questionnaire. Data obtained from the survey were analysed through appropriate summary statistics, analysis of variance (ANOVA) and logistic regression analysis. 670 medical practitioners participated in the online survey. Among them, 508 stated that they knew of AAI. 93.7% of these described themselves fully favourable towards the use of the human-animal relationship for therapeutic purposes, 84.4% defined themselves as confident and interested in studying the theme. A positive attitude towards AAI was greater in females, in people between 45 and 54 years old, in those who are pet owners and in those who believe that conferences are the most suitable tool to share information on AAI. The chance of having a positive attitude towards AAI is higher in respondents with specific characteristics. Data collected could be used as a starting point to promote and implement communication and training activities on AAI addressed to medical practitioners. Copyright © 2017 Elsevier Ltd.

Neurodegeneration and Identity.

PubMed

Strohminger, Nina; Nichols, Shaun

2015-09-01

There is a widespread notion, both within the sciences and among the general public, that mental deterioration can rob individuals of their identity. Yet there have been no systematic investigations of what types of cognitive damage lead people to appear to no longer be themselves. We measured perceived identity change in patients with three kinds of neurodegenerative disease: frontotemporal dementia, Alzheimer's disease, and amyotrophic lateral sclerosis. Structural equation models revealed that injury to the moral faculty plays the primary role in identity discontinuity. Other cognitive deficits, including amnesia, have no measurable impact on identity persistence. Accordingly, frontotemporal dementia has the greatest effect on perceived identity, and amyotrophic lateral sclerosis has the least. We further demonstrated that perceived identity change fully mediates the impact of neurodegenerative disease on relationship deterioration between patient and caregiver. Our results mark a departure from theories that ground personal identity in memory, distinctiveness, dispositional emotion, or global mental function. © The Author(s) 2015.

Krajcovicová-Kudlácková, M; Simoncic, R; Béderová, A; Klvanová, J

1997-01-01

Plasma profile of fatty acids was examined in a group of children consisting of 7 vegans, 15 lactoovovegetarians and 10 semivegetarians. The children were 11-15 years old and the average period of alternative nutrition was 3.4 years. The results were compared with a group of 19 omnivores that constituted an average sample with respect to biochemical and hematological parameters from a larger study of health and nutritional status of children in Slovakia. Alternative nutrition groups had significantly lower values of saturated fatty acids. The content of oleic acid was identical to omnivores. A significant increase was observed for linoleic and alpha-linolenic (n-3) acids. The dihomo-gamma-linolenic (n-6) acid and arachidonic (n-6) acid values were comparable to omnivores for all alternative nutrition groups. Values of n-3 polyunsaturated fatty acids in lactoovovegetarians were identical to those of omnivores whereas they were significantly increased in semivegetarians consuming fish twice a week. Due to the total exclusion of animal fats from the diet, vegans had significantly reduced values of palmitoleic acid as well as eicosapentaenoic (n-3) acid and docosahexaenoic (n-3) acid resulting in an increased n-6/n-3 ratio. Values of plasma fatty acids found in alternative nutrition groups can be explained by the higher intake of common vegetable oils (high content of linoleic acid), oils rich in alpha-linolenic acid (cereal germs, soybean oil, walnuts), as well as in n-3 polyunsaturated fatty acids (fish). The results of fatty acids (except n-3 in vegans) and other lipid parameters confirm the beneficial effect of vegetarian nutrition in the prevention of cardiovascular diseases.

SuperIdentity: Fusion of Identity across Real and Cyber Domains

DOE Office of Scientific and Technical Information (OSTI.GOV)

Black, Sue; Creese, Sadie; Guest, Richard

Under both benign and malign circumstances, people now manage a spectrum of identities across both real-world and cyber domains. Our belief, however, is that all these instances ultimately track back for an individual to reflect a single 'SuperIdentity'. This paper outlines the assumptions underpinning the SuperIdentity Project, describing the innovative use of data fusion to incorporate novel real-world and cyber cues into a rich framework appropriate for modern identity. The proposed combinatorial model will support a robust identification or authentication decision, with confidence indexed both by the level of trust in data provenance, and the diagnosticity of the identity factorsmore » being used. Additionally, the exploration of correlations between factors may underpin the more intelligent use of identity information so that known information may be used to predict previously hidden information. With modern living supporting the 'distribution of identity' across real and cyber domains, and with criminal elements operating in increasingly sophisticated ways in the hinterland between the two, this approach is suggested as a way forwards, and is discussed in terms of its impact on privacy, security, and the detection of threat.« less

2015-12-01

Adopted Korean adolescents face the task of grappling with their identity as Koreans and coming to terms with their adoptive status. In order to explore these dual identities, the authors conducted a person-centered study of the identity profiles of 189 adopted Korean American adolescents. Using cluster analytic procedures, the study examined patterns of commitment to ethnic and adoptive identities, revealing six conceptually unique identity clusters. Analyzing the association between these identity profiles and psychological adjustment, the study found that the identity profiles were undifferentiated with respect to behavioral development and risk behaviors. However, group differences were found on life satisfaction, school adjustment, and family functioning. Results confirm the importance of considering the collective impact of multiple social identities on a variety of outcomes. The social implications of the results are discussed. © 2015 Wiley Periodicals, Inc.

Men who have sex with men (MSM) remain at high risk for HIV infection. Culturally specific sexual identities, encompassing sexual roles, behavior, and appearance, may shape MSM's experiences of stigmatization and discrimination, and affect their vulnerability to HIV. This multi-site qualitative study (n = 363) encompassing 31 focus group discussions (FGDs) and 121 in-depth interviews (IDIs) across 15 sites in India investigated sexual identity formation, identity practices, and transitions and their implications for HIV prevention. IDIs and FGDs were transcribed, translated, and underwent thematic analysis. Our findings document heterogeneous sexual identity formation, with MSM who have more gender nonconforming behaviors or appearance reporting greater family- and community-level disapproval, harassment, violence, and exclusion. Concealing feminine aspects of sexual identities was important in daily life, especially for married MSM. Some participants negotiated their identity practices in accordance with socioeconomic and cultural pressures, including taking on identity characteristics to suit consumer demand in sex work and on extended periods of joining communities of hijras (sometimes called TG or transgender women). Participants also reported that some MSM transition toward more feminine and hijra or transgender women identities, motivated by intersecting desires for feminine gender expression and by social exclusion and economic marginalization. Future studies should collect information on gender nonconformity stigma, and any changes in sexual identity practices or plans for transitions to other identities over time, in relation to HIV risk behaviors and outcomes.

A longitudinal integration of identity styles and educational identity processes in adolescence.

2017-11-01

Identity formation is a main adolescent psychosocial developmental task. The complex interconnection between different processes that are at the basis of one's identity is a research and applied intervention priority. In this context, the identity style model focuses on social-cognitive strategies (i.e., informational, normative, and diffuse-avoidant) that individuals can use to deal with identity formation. The 3-factor identity dimensional model examines the interplay between identity processes of commitment, in-depth exploration, and reconsideration of commitment in different life domains. Theoretical integrations between these models have been proposed, but there is a dearth of studies unraveling their longitudinal links in specific identity domains. We addressed this gap by testing in a 3-wave longitudinal study the bidirectional associations between identity styles and educational identity processes measured during 1 academic year. Participants were 1,151 adolescents (58.7% female). Results highlighted that the informational style was related over time to higher levels of educational commitment and in-depth exploration, whereas the diffuse-avoidant style was related to lower levels of commitment and higher levels of reconsideration of commitment. Educational commitment was positively related to the informational and normative styles; in-depth exploration was positively related to the informational style; and reconsideration of commitment was positively related to the diffuse-avoidant style. These relations were not moderated by adolescents' gender and age. Hence, identity styles and educational identity processes reinforce each other during 1 academic year. Theoretical integrations between these models, suggestions for integration with other identity approaches (e.g., narrative identity models), and practical implications are discussed.

Political, religious and occupational identities in context: placing identity status paradigm in context.

PubMed

Solomontos-Kountouri, Olga; Hurry, Jane

2008-04-01

This study critically contrasts global identity with domain-specific identities (political, religious and occupational) and considers context and gender as integral parts of identity. In a cross-sectional survey, 1038 Greek Cypriot adolescents (449 boys and 589 girls, mean age 16.8) from the three different types of secondary schools (state, state technical and private) and from different SES completed part of the Extended Objective Measure of Ego Identity Status-2 (EOMEIS-2). The macro-context of Greek Cypriot society is used to understand the role of context in adolescents' identities. Results showed that Greek Cypriot young people were not in the same statuses across their global, political, religious and occupational identities. This heterogeneity in the status of global identity and of each identity domain is partially explained by differences in gender, type of school and SES (socio-economic status). The fact that identity status is found to be reactive to context suggests that developmental stage models of identity status should place greater emphasis on context.

2017-11-25

The purpose of the present review was threefold: to address the current state of Animal-Assisted Interactions (AAI) within the military; to summarize recent literature (within the past three years) in the field of AAI; and to discuss trends in AAI research since 2014. With regard to AAI within the military, several canine interaction programs have been utilized to assist service members in coping with various issues. Therapy dogs have been deployed with Combat-Operational Stress Control units; they have been integrated into medical clinics and behavioral health treatment programs in garrison; and policy has been developed to address the use of therapy animals in military treatment facilities. General research in AAI has demonstrated efficacy for certain presenting issues (stress management, trauma, autism spectrum disorder) and specific populations (children, the elderly, acute care patients). Overall trends in research include calls for increased consideration for animal welfare in AAI and increased rigor in research methodology. Current research supports the structured use of therapy dogs in the treatment of various disorders and with specific populations, including military service members and veterans; however, the need for additional research with rigorous methodology remains.

Shades of American Identity: Implicit Relations between Ethnic and National Identities

PubMed Central

Devos, Thierry; Mohamed, Hafsa

2015-01-01

The issue of ethnic diversity and national identity in an immigrant nation such as the USA is a recurrent topic of debate. We review and integrate research examining the extent to which the American identity is implicitly granted or denied to members of different ethnic groups. Consistently, European Americans are implicitly conceived of as being more American than African, Asian, Latino, and even Native Americans. This implicit American = White effect emerges when explicit knowledge or perceptions point in the opposite direction. The propensity to deny the American identity to members of ethnic minorities is particularly pronounced when targets (individuals or groups) are construed through the lenses of ethnic identities. Implicit ethnic–national associations fluctuate as a function of perceivers’ ethnic identity and political orientation, but also contextual or situational factors. The tendency to equate being American with being White accounts for the strength of national identification (among European Americans) and behavioral responses including hiring recommendations and voting intentions. The robust propensity to deny the American identity to ethnic minority groups reflects an exclusionary national identity. PMID:27011765

Identity configurations: a new perspective on identity formation in contemporary society.

PubMed

Schachter, Elli P

2004-02-01

This paper deals with the theoretical construct of "identity configuration." It portrays the different possible ways in which individuals configure the relationship among potentially conflicting identifications in the process of identity formation. In order to explicate these configurations, I analyzed narratives of identity development retold by individuals describing personal identity conflicts that arise within a larger context of sociocultural conflict. Thirty Jewish modern orthodox young adults were interviewed regarding a potentially conflictual identity issue (i.e. their religious and sexual development). Their deliberations, as described in the interviews, were examined, and four different configurations were identified: a configuration based on choice and suppression; an assimilative and synthesizing configuration; a confederacy of identifications; and a configuration based on the thrill of dissonance. The different configurations are illustrated through exemplars, and the possible implications of the concept of "configuration" for identity theory are discussed.

To investigate whether human breast milk contains potentially probiotic lactic acid bacteria, and therefore, whether it can be considered a synbiotic food. Study design Lactic acid bacteria were isolated from milk, mammary areola, and breast skin of eight healthy mothers and oral swabs and feces of their respective breast-fed infants. Some isolates (178 from each mother and newborn pair) were randomly selected and submitted to randomly amplified polymorphic DNA (RAPD) polymerase chain reaction analysis, and those that displayed identical RAPD patterns were identified by 16S rDNA sequencing. Within each mother and newborn pair, some rod-shaped lactic acid bacteria isolated from mammary areola, breast milk, and infant oral swabs and feces displayed identical RAPD profiles. All of them, independently from the mother and child pair, were identified as Lactobacillus gasseri. Similarly, among coccoid lactic acid bacteria from these different sources, some shared an identical RAPD pattern and were identified as Enterococcus faecium. In contrast, none of the lactic acid bacteria isolated from breast skin shared RAPD profiles with lactic acid bacteria of the other sources. Breast-feeding can be a significant source of lactic acid bacteria to the infant gut. Lactic acid bacteria present in milk may have an endogenous origin and may not be the result of contamination from the surrounding breast skin.

In this study, we present the identification and characterization of hamster and guinea pig nicotinic acid receptors. The hamster receptor shares approximately 80-90% identity with the nucleotide and amino acid sequences of human, mouse, and rat receptors. The guinea pig receptor shares 76-80% identity with the nucleotide and amino acid sequences of these other species. [(3)H]nicotinic acid binding affinity at guinea pig and hamster receptors is similar to that in human (dissociation constant = 121 nM for guinea pig, 72 nM for hamster, and 74 nM for human), as are potencies of nicotinic acid analogs in competition binding studies. Inhibition of forskolin-stimulated cAMP production by nicotinic acid and related analogs is also similar to the activity in the human receptor. Analysis of mRNA tissue distribution for the hamster and guinea pig nicotinic acid receptors shows expression across a number of tissues, with higher expression in adipose, lung, skeletal muscle, spleen, testis, and ovary.

The alcohol-soluble fraction of wheat gluten (gliadins) induces in genetically susceptible individuals immunologically mediated celiac disease (CLD). However, gliadins and related cereal proteins are not unique foodstuff targets of CLD patients´ immune system. Non-gluten wheat alpha-amylase inhibitor 0.19 (AAI 0.19) has been found to be capable of activating human monocyte-derived dendritic cells and inducing pro-inflammatory status in intestinal mucosa of patients with celiac disease (CLD). The possible contribution of this reactivity in incomplete remission of CLD patients on a gluten-free diet (GFD) is matter of contention. In an attempt to characterize the antigenicity of AAI 0.19 in patients with active CLD, patients on a GFD and healthy controls we developed ELISA employing wheat recombinant AAI 0.19. Using this test we revealed a significant (P<0.001) elevation of IgA anti-AAI 0.19 antibodies (Ab) in patients with active CLD (12 out of 30 patients were seropositive) but also in CLD patients on a GFD (15/46), in contrast to healthy controls (2/59). Anti-AAI 0.19 IgG Ab levels were increased (P<0.001) only in patients with active CLD (14/30) in contrast to the controls. Interestingly, the levels of anti-AAI 0.19 IgG Ab were decreased in CLD patients on a GFD (P<0.001, 1/46) compared to the controls (1/59). Notably, 20 out of 30 of patients with active CLD were positive either for IgA or for IgG anti-AAI 0.19 Ab. Thus, the majority of CLD patients developed a robust IgA and IgG Ab response against AAI 0.19. These findings may contribute to the broadening of the knowledge about CLD pathogenesis.

Current Perspectives on Therapy Dog Welfare in Animal-Assisted Interventions

Simple Summary In animal-assisted interventions (AAIs) animals are used as adjuncts to therapy to positively affect human health. The practice of implementing dogs into therapeutic environments is emerging and as a result, there has been a growing scientific interest on human health outcomes over the past decades. Research efforts into the canine perspective of AAIs have been scarce. Accordingly, there is little consensus on the impact of such interventions on the animals involved. This paper aimed to contribute to the limited body of knowledge by reviewing available studies on therapy dogs’ welfare during AAIs.

The digestive tract lymphatics transport approximately two-thirds of all lymph produced in the body and have a key role in mucosal immunity through their contribution to antigen transport and immune cell trafficking. Mesenteric lymphatic pumping function integrity is critical for maintaining homeostasis and lipid transport. We previously demonstrated that acute alcohol intoxication (AAI) increases mesenteric lymphatic amplitude of contraction and ejection fraction, enhancing the ability of the lymphatic vessels to pump lymph. AAI has been shown to disrupt intestinal barrier integrity, which would be expected to increase the endotoxin content of mesenteric lymph. In this study, we tested the prediction that AAI increases lymphatic permeability directly affecting perilymphatic adipose tissue (PLAT) milieu. Male Sprague Dawley rats received an intragastric infusion of 2.5 g/kg of alcohol. Isovolumic administration of water (vehicle) served as control. PLAT was isolated for the determination of Evans Blue extravasation (permeability), cytokine content, and immunohistochemistry for inflammatory cell infiltration at 30 minutes and 24 hours after alcohol administration. PLAT isolated from AAI animals had greater Evans Blue concentrations and cytokine expression (24 hours post-AAI) and mast cell and neutrophil density than that isolated from controls. AAI resulted in significantly higher plasma lipopolysaccharide (endotoxin) levels, lower plasma adiponectin levels (at 30 minutes), and unchanged plasma visfatin levels. The data indicate that AAI induces mesenteric lymphatic hyperpermeability, promotes PLAT inflammatory milieu and disrupts the systemic adipokine profile. These findings suggest an association between alcohol-induced lymphatic hyperpermeability and early manifestations of metabolic dysfunction as a result of alcohol abuse. We propose that crosstalk between lymph and PLAT results in adipose inflammation and adipokine dysregulation during AAI. Copyright �

We compared clinical outcomes after ventral fixation in dogs with atlantoaxial instability (AAI) on the basis of the presence or absence of atlantooccipital overlapping (AOO). Of 41 dogs diagnosed with AAI and treated ventral fixation, 12 exhibited AOO (AOO group), whereas 29 did not (non-AOO group). The AOO group had significantly higher neurological scores before (P=0.024) and 1 month after (P=0.033) surgery compared with the non-AOO group; however, no significant differences were observed between the groups 2 months after surgery. The presence of complicating AOO affected the clinical signs for dogs with AAI, but did not directly affect the outcome of surgical stabilization of AAI. PMID:29398673

This qualitative study was conducted to explore the images of personal identity from the perspective of women with sexual addiction. The data required for the study were collected through 31 in-depth interviews. Sensing a threat to personal identity, dissatisfaction with gender identity, dissociation with the continuum of identity, and identity reconstruction in response to threat were four of the experiences that were common among women with sexual addiction. Painful emotional experiences appear to have created a sense of gender and sexual conflict or weakness in these women and thus threatened their personal identity and led to their sexual addiction.

Animal-assisted interventions: A national survey of health and safety policies in hospitals, eldercare facilities, and therapy animal organizations.

Animal-assisted intervention (AAI) programs are increasing in popularity, but it is unknown to what extent therapy animal organizations that provide AAI and the hospitals and eldercare facilities they work with implement effective animal health and safety policies to ensure safety of both animals and humans. Our study objective was to survey hospitals, eldercare facilities, and therapy animal organizations on their AAI policies and procedures. A survey of United States hospitals, eldercare facilities, and therapy animal organizations was administered to assess existing health and safety policies related to AAI programs. Forty-five eldercare facilities, 45 hospitals, and 27 therapy animal organizations were surveyed. Health and safety policies varied widely and potentially compromised human and animal safety. For example, 70% of therapy animal organizations potentially put patients at risk by allowing therapy animals eating raw meat diets to visit facilities. In general, hospitals had stricter requirements than eldercare facilities. This information suggests that there are gaps between the policies of facilities and therapy animal organizations compared with recent guidelines for animal visitation in hospitals. Facilities with AAI programs need to review their policies to address recent AAI guidelines to ensure the safety of animals and humans involved.

2013-06-01

The aim of this literature review was to assess the effects of Animal-Assisted Interventions (AAI) on elderly patients with dementia or various psychiatric disorders. We conducted a comprehensive literature search using the online PubMed network of the US National Library of Medicine & National Institutes of Health, Embase, PsycINFO, with the purpose of investigating AAI effects on cognitive functions, mood, and behaviour. A total of 18 articles on dementia and 5 on psychiatric disorders were included in the present review. AAI were found to have positive influences on demented patients by reducing degree of agitation and by improving degree and quality of social interaction. Few studies have assessed the effects of AAI on mood, and even fewer have assessed its consequences on cognitive functions. The results that are available indicate a positive effect on communication and coping ability, but none on cognitive performance. A substitute pet robot yielded encouraging results, but its use requires further investigation. The few studies conducted for elderly patients presenting a variety of psychiatric diagnoses produced controversial findings. In spite of the encouraging results of AAI, much more research examining the issue of optimal AAI duration, frequency of sessions, and suitable target group is needed. Copyright © 2013 Elsevier Ltd.

Thinking identity differently: dynamics of identity in self and institutional boundary

2011-03-01

In research oriented universities, research and teaching are often viewed as separate. Aydeniz and Hodge present one professor's struggles to synthesize an identity from three different spaces, each with competing values and core beliefs. As Mr. G's story unfolds, and he reflects upon his negotiation between teaching and research responsibilities, we seek to expand the discussion by presenting a caution to identity researchers. The caution pertains to construction of understanding on how identities are created, and the role that individual stories take in how identities are created and enacted. In this forum contribution, we present several questions in the hopes of furthering the discussion on identity research, and our understanding of the conceptualization of institutional boundaries and objectivity, as well as questions on participant involvement in the process of research.

Precursors of vertebrate peptide antibiotics dermaseptin b and adenoregulin have extensive sequence identities with precursors of opioid peptides dermorphin, dermenkephalin, and deltorphins.

The dermaseptins are a family of broad spectrum antimicrobial peptides, 27-34 amino acids long, involved in the defense of the naked skin of frogs against microbial invasion. They are the first vertebrate peptides to show lethal effects against the filamentous fungi responsible for severe opportunistic infections accompanying immunodeficiency syndrome and the use of immunosuppressive agents. A cDNA library was constructed from skin poly(A+) RNA of the arboreal frog Phyllomedusa bicolor and screened with an oligonucleotide probe complementary to the COOH terminus of dermaseptin b. Several clones contained a full-length DNA copy of a 443-nucleotide mRNA that encoded a 78-residue dermaseptin b precursor protein. The deduced precursor contained a putative signal sequence at the NH2 terminus, a 20-residue spacer sequence extremely rich (60%) in glutamic and aspartic acids, and a single copy of a dermaseptin b progenitor sequence at the COOH terminus. One clone contained a complete copy of adenoregulin, a 33-residue peptide reported to enhance the binding of agonists to the A1 adenosine receptor. The mRNAs encoding adenoregulin and dermaseptin b were very similar: 70 and 75% nucleotide identities between the 5'- and 3'-untranslated regions, respectively; 91% amino acid identity between the signal peptides; 82% identity between the acidic spacer sequences; and 38% identity between adenoregulin and dermaseptin b. Because adenoregulin and dermaseptin b have similar precursor designs and antimicrobial spectra, adenoregulin should be considered as a new member of the dermaseptin family and alternatively named dermaseptin b II. Preprodermaseptin b and preproadenoregulin have considerable sequence identities to the precursors encoding the opioid heptapeptides dermorphin, dermenkephalin, and deltorphins. This similarity extended into the 5'-untranslated regions of the mRNAs. These findings suggest that the genes encoding the four preproproteins are all members of the same family

Social Identity in People with Multiple Sclerosis: An Examination of Family Identity and Mood.

2018-01-01

Mood disorders are highly prevalent in people with multiple sclerosis (MS). MS causes changes to a person's sense of self. The Social Identity Model of Identity Change posits that group membership can have a positive effect on mood during identity change. The family is a social group implicated in adjustment to MS. The objectives of this study were to investigate whether family identity can predict mood in people with MS and to test whether this prediction was mediated by social support and connectedness to others. This cross-sectional survey of 195 participants comprised measures of family identity, family social support, connectedness to others, and mood. Family identity predicted mood both directly and indirectly through parallel mediators of family social support and connectedness to others. Family identity predicted mood as posited by the Social Identity Model of Identity Change. Involving the family in adjustment to MS could reduce low mood.

Identity-specific motivation: How distinct identities direct self-regulation across distinct situations.

PubMed

Browman, Alexander S; Destin, Mesmin; Molden, Daniel C

2017-12-01

Research on self-regulation has traditionally emphasized that people's thoughts and actions are guided by either (a) domain-general motivations that emerge from a cumulative history of life experiences, or (b) situation-specific motivations that emerge in immediate response to the incentives present in a particular context. However, more recent studies have illustrated the importance of understanding the interplay between such domain-general and situation-specific motivations across the types of contexts people regularly encounter. The present research, therefore, expands existing perspectives on self-regulation by investigating how people's identities -the internalized roles, relationships, and social group memberships that define who they are-systemically guide when and how different domain-general motivations are activated within specific types of situations. Using the motivational framework described by regulatory focus theory (Higgins, 1997), Studies 1 and 2 demonstrate that people indeed have distinct, identity-specific motivations that uniquely influence their current self-regulation when such identities are active. Studies 3-5 then begin to explore how identity-specific motivations are situated within people's larger self-concept. Studies 3a and 3b demonstrate that the less compatible people's specific identities, the more distinct are the motivations connected to those identities. Studies 4-5 then provide some initial, suggestive evidence that identity-specific motivations are not a separate, superordinate feature of people's identities that then alter how they pursue any subordinate, identity-relevant traits, but instead that such motivations emerge from the cumulative motivational significance of the subordinate traits to which the identities themselves become attached. Implications for understanding the role of the self-concept in self-regulation are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Social Identity and Preferences*

Social identities prescribe behaviors for people. We identify the marginal behavioral effect of these norms on discount rates and risk aversion by measuring how laboratory subjects’ choices change when an aspect of social identity is made salient. When we make ethnic identity salient to Asian-American subjects, they make more patient choices. When we make racial identity salient to black subjects, non-immigrant blacks (but not immigrant blacks) make more patient choices. Making gender identity salient has no effect on intertemporal or risk choices. PMID:20871741

Comparison of Brain Activity Correlating with Self-Report versus Narrative Attachment Measures during Conscious Appraisal of an Attachment Figure.

Yaseen, Zimri S; Zhang, Xian; Muran, J Christopher; Winston, Arnold; Galynker, Igor I

2016-01-01

The Adult Attachment Interview (AAI) has been the gold standard of attachment assessment, but requires special training. The Relationship Scales Questionnaire (RSQ) is a widely used self-report measure. We investigate how each correlates with brain activity during appraisal of subjects' mothers. Twenty-eight women were scored on the AAI, RSQ, and mood measures. During functional magnetic resonance imaging, subjects viewed their mothers in neutral-, valence-, and salience-rating conditions. We identified regions where contrasts in brain activity between appraisal and neutral viewing conditions correlated with each measure of attachment after covarying for mood. AAI and RSQ measures were then compared in terms of the extent to which regions of correlating brain activity overlapped with "default mode network" (DMN) vs. executive frontal network (EFN) masks and cortical vs. subcortical masks. Additionally, interactions with mood were examined. Salience and valence processing associated with increased thalamo-striatal, posterior cingulate, and visual cortex activity. Salience processing decreased PFC activity, whereas valence processing increased left insula activity. Activity correlating with AAI vs. RSQ measures demonstrated significantly more DMN and subcortical involvement. Interactions with mood were observed in the middle temporal gyrus and precuneus for both measures. The AAI appears to disproportionately correlate with conscious appraisal associated activity in DMN and subcortical structures, while the RSQ appears to tap EFN structures more extensively. Thus, the AAI may assess more interoceptive, 'core-self'-related processes, while the RSQ captures higher-order cognitions involved in attachment. Shared interaction effects between mood and AAI and RSQ-measures may suggest that processes tapped by each belong to a common system.

Memory transfer for emotionally valenced words between identities in dissociative identity disorder.

2007-04-01

The present study aimed to determine interidentity retrieval of emotionally valenced words in dissociative identity disorder (DID). Twenty-two DID patients participated together with 25 normal controls and 25 controls instructed to simulate DID. Two wordlists A and B were constructed including neutral, positive and negative material. List A was shown to one identity, while list B was shown to another identity claiming total amnesia for the words learned by the first identity. The identity claiming amnesia was tested for intrusions from list A words into the recall of words from list B and recognition of the words learned by both identities. Test results indicated no evidence of total interidentity amnesia for emotionally valenced material in DID. It is argued that dissociative amnesia in DID may more adequately be described as a disturbance in meta-memory functioning instead of an actual retrieval inability.

Identity and Professional Networking.

PubMed

Raj, Medha; Fast, Nathanael J; Fisher, Oliver

2017-06-01

Despite evidence that large professional networks afford a host of financial and professional benefits, people vary in how motivated they are to build such networks. To help explain this variance, the present article moves beyond a rational self-interest account to examine the possibility that identity shapes individuals' intentions to network. Study 1 established a positive association between viewing professional networking as identity-congruent and the tendency to prioritize strengthening and expanding one's professional network. Study 2 revealed that manipulating the salience of the self affects networking intentions, but only among those high in networking identity-congruence. Study 3 further established causality by experimentally manipulating identity-congruence to increase networking intentions. Study 4 examined whether identity or self-interest is a better predictor of networking intentions, providing support for the former. These findings indicate that identity influences the networks people develop. Implications for research on the self, identity-based motivation, and professional networking are discussed.

Animal-assisted intervention for autism spectrum disorder: a systematic literature review.

PubMed

O'Haire, Marguerite E

2013-07-01

The inclusion of animals in therapeutic activities, known as animal-assisted intervention (AAI), has been suggested as a treatment practice for autism spectrum disorder (ASD). This paper presents a systematic review of the empirical research on AAI for ASD. Fourteen studies published in peer-reviewed journals qualified for inclusion. The presentation of AAI was highly variable across the studies. Reported outcomes included improvements for multiple areas of functioning known to be impaired in ASD, namely increased social interaction and communication as well as decreased problem behaviors, autistic severity, and stress. Yet despite unanimously positive outcomes, most studies were limited by many methodological weaknesses. This review demonstrates that there is preliminary "proof of concept" of AAI for ASD and highlights the need for further, more rigorous research.

Men as victims: "victim" identities, gay identities, and masculinities.

PubMed

Dunn, Peter

2012-11-01

The impact and meanings of homophobic violence on gay men's identities are explored with a particular focus on their identities as men and as gay men. Homosexuality can pose a challenge to conventional masculinities, and for some gay men, being victimized on account of sexual orientation reawakens conflicts about their masculinity that they thought they had resolved. Being victimized can reinvoke shame that is rooted in failure or unwillingness to uphold masculine norms. For some gay men, victimization therefore has connotations of nonmasculinity that make being a victim an undesirable status, yet that status must be claimed to obtain a response from criminal justice or victim services. Men who experience homophobic abuse are helped by accepting a victim identity, but only if they can quickly move on from it by reconstructing a masculine gay (nonvictim) identity. This process can be facilitated by agencies such as the police and victim services, provided they help men exercise agency in "fighting back," that is, resisting further victimization and recovering.

Exploring medical identity theft.

2009-09-16

The crime of medical identity theft is a growing concern in healthcare institutions. A mixed-method study design including a two-stage electronic survey, telephone survey follow-up, and on-site observations was used to evaluate current practices in admitting and registration departments to reduce the occurrence of medical identity theft. Survey participants were chief compliance officers in acute healthcare organizations and members of the Health Care Compliance Association. Study results indicate variance in whether or how patient identity is confirmed in healthcare settings. The findings of this study suggest that information systems need to be designed for more efficient identity management. Admitting and registration staff must be trained, and compliance with medical identity theft policies and procedures must be monitored. Finally, biometric identity management solutions should be considered for stronger patient identification verification.

Identity as a 'patchwork': aspects of identity among low-income Brazilian travestis.

PubMed

Garcia, Marcos Roberto Vieira

2009-08-01

This paper is based on findings from a qualitative study that took place within the context of a four-year healthcare programme directed towards low-income travestis in the central area of Sao Paulo, Brazil. Throughout the study the formation of social identity among travestis was investigated through a focus on four axes: gender, body, work and violence. This paper subjects the identity of the travestis to a critical analysis and proposes a view of their sense of self as a 'patchwork' assembled through the assimilation of various fragments of identity common in Brazilian society. The primary identities assimilated by the travestis under study were, in the area of femininity, the submissive woman, the puta ['whore'] and the super-seductive woman and, in the area of masculinity, the viado ['queer'], the malandro ['rascal'] and the bandido ['bandit']. The resulting travesti identity exhibited not only gender ambiguity, but also contradictions among the feminine identities described, as well as among the masculine ones.

Broken identity: the impact of the Holocaust on identity in Romanian and Polish Jews.

2008-01-01

The paper is based on interviews conducted with Holocaust survivors in Poland (30 interviews) and Romania (55 interviews). It describes how the Holocaust affected survivor identity. Two aspects of identity are analyzed the sense of personal identity and social identity. Each affects the other but they are largely independent and the trauma of the Holocaust impacted each of them differently. Personal identity seems to be unrelated to either the type of trauma or the survivor's social situation. There are no significant differences in that aspect between Polish and Romanian survivors. Social identity is more related to the survivors' social situation prior to and after the trauma. The sense of identity, both personal and social, is dynamic and changes over time.

Research outcomes are discussed in the light of strengths and weaknesses of the methods used. Study results suggest that frequency and duration of AAI sessions, novelty of the environment, controllability, age and familiarity of recipients modulate animal welfare indicators. However, this review reveals that currently, clear conclusions on how the well-being of dogs is influenced by the performance in AAIs are lacking due to the heterogeneity of programs, recipient and session characteristics, small dog sample sizes and methodological limitations.

Coming to an Asexual Identity: Negotiating Identity, Negotiating Desire.

Scherrer, Kristin S

2008-10-01

Sexuality is generally considered an important aspect of self-hood. Therefore, individuals who do not experience sexual attraction, and embrace an asexual identity are in a unique position to inform the social construction of sexuality. This study explores the experiences of asexual individuals utilizing open ended Internet survey data from 102 self-identified asexual people. In this paper I describe several distinct aspects of asexual identities: the meanings of sexual, and therefore, asexual behaviors, essentialist characterizations of asexuality, and lastly, interest in romance as a distinct dimension of sexuality. These findings have implications not only for asexual identities, but also for the connections of asexuality with other marginalized sexualities.

Unmasking identity dissonance: exploring medical students' professional identity formation through mask making.

Joseph, Kimera; Bader, Karlen; Wilson, Sara; Walker, Melissa; Stephens, Mark; Varpio, Lara

2017-04-01

Professional identity formation is an on-going, integrative process underlying trainees' experiences of medical education. Since each medical student's professional identity formation process is an individual, internal, and often times emotionally charged unconscious experience, it can be difficult for educators to understand each student's unique experience. We investigate if mask making can provide learners and educators the opportunity to explore medical students' professional identity formation experiences. In 2014 and 2015, 30 third year medical students created masks, with a brief accompanying written narrative, to creatively express their medical education experiences. Using a paradigmatic case selection approach, four masks were analyzed using techniques from visual rhetoric and the Listening Guide. The research team clearly detected identity dissonance in each case. Each case provided insights into the unique personal experiences of the dissonance process for each trainee at a particular point in their medical school training. We propose that mask making accompanied by a brief narrative reflection can help educators identify students experiencing identity dissonance, and explore each student's unique experience of that dissonance. The process of making these artistic expressions may also provide a form of intervention that can enable educators to help students navigate professional identity formation and identity dissonance experiences.

Atlanto-axial instability (AAI) is a developmental anomaly often occurring in persons with Down's syndrome (DS). According to various reports, AAI affects from 6.8 to 27% of the population with DS. The aim of this review was to illustrate the issue of AAI with regard to the progressively changing state of scientific knowledge. The extended distance between the rear surface of the frontal arcus of the C1 cervical vertebra and the anterior surface of C2 cervical vertebra dens (anterior atlanto-odontoid distance, AAOD) indicates the occurrence of AAI and is detectable through X-ray examination. Hypoplasia of the C2 dens, also detectable through X-ray examination, is another suggested risk factor for AAI. According to current data, the methodology of taking measurements is inconsistent, which leads to errors in interpretation. As research focusing on AAI was progressing, new data emerged from other studies on persons with DS, suggesting that neurological symptoms in persons with DS that indicated the occurrence of spinal cord compression were an important factor in medical imaging detection of AAI. One of the main arguments supporting this thesis is that in isolated cases spinal cord (SC) damage was noted during screening examinations conducted on a large population of subjects. Moreover, cases in which the neurological symptoms indicate spinal cord compression existed long before the occurrence of the actual damage also remain of significant importance. Therefore, it is necessary to promote neurological studies on persons with DS to enable early diagnosis of spinal cord compression and, at the same time, reduce the use of medical imaging in cases of neurological symptoms.

Objectives: The Adult Attachment Interview (AAI) has been the gold standard of attachment assessment, but requires special training. The Relationship Scales Questionnaire (RSQ) is a widely used self-report measure. We investigate how each correlates with brain activity during appraisal of subjects’ mothers. Methods: Twenty-eight women were scored on the AAI, RSQ, and mood measures. During functional magnetic resonance imaging, subjects viewed their mothers in neutral-, valence-, and salience-rating conditions. We identified regions where contrasts in brain activity between appraisal and neutral viewing conditions correlated with each measure of attachment after covarying for mood. AAI and RSQ measures were then compared in terms of the extent to which regions of correlating brain activity overlapped with “default mode network” (DMN) vs. executive frontal network (EFN) masks and cortical vs. subcortical masks. Additionally, interactions with mood were examined. Results: Salience and valence processing associated with increased thalamo-striatal, posterior cingulate, and visual cortex activity. Salience processing decreased PFC activity, whereas valence processing increased left insula activity. Activity correlating with AAI vs. RSQ measures demonstrated significantly more DMN and subcortical involvement. Interactions with mood were observed in the middle temporal gyrus and precuneus for both measures. Conclusion: The AAI appears to disproportionately correlate with conscious appraisal associated activity in DMN and subcortical structures, while the RSQ appears to tap EFN structures more extensively. Thus, the AAI may assess more interoceptive, ‘core-self’-related processes, while the RSQ captures higher-order cognitions involved in attachment. Shared interaction effects between mood and AAI and RSQ-measures may suggest that processes tapped by each belong to a common system. PMID:27014022

To determine whether a disintegrin and a metalloproteinase-8 (Adam8) regulates allergic airway inflammation (AAI) and airway hyper-responsiveness (AHR), we compared AAI and AHR in wild type (WT) versus Adam8−/− mice in different genetic backgrounds sensitized and challenged with ovalbumin (OVA) or house dust mite protein extract (HDM). OVA- and HDM-treated Adam8−/− mice had higher lung leukocyte counts, more airway mucus metaplasia, greater lung levels of some TH2 cytokines, and higher methacholine-induced increases in central airway resistance than allergen-treated WT mice. Studies of OVA-treated Adam8 bone marrow chimeric mice confirmed that leukocyte-derived Adam8 predominantly mediated Adam8’s anti-inflammatory activities in murine airways. Airway eosinophils and macrophages both expressed Adam8 in WT mice with AAI. Adam8 limited AAI and AHR in mice by reducing leukocyte survival because: 1) Adam8−/− mice with AAI had fewer apoptotic eosinophils and macrophages in their airways than WT mice with AAI; and 2) Adam8−/− macrophages and eosinophils had reduced rates of apoptosis compared with WT leukocytes when the intrinsic (but not the extrinsic) apoptosis pathway was triggered in the cells in vitro. ADAM8 was robustly expressed by airway granulocytes in lung sections from human asthma patients but, surprisingly, airway macrophages had less ADAM8 staining than airway eosinophils. Thus, ADAM8 has anti-inflammatory activities during AAI in mice by activating the intrinsic apoptosis pathway in myeloid leukocytes. Strategies that increase ADAM8 levels in myeloid leukocytes may have therapeutic efficacy in asthma. PMID:23670189

Studies on physics identity are appearing more frequently and often responding to increased awareness of the underrepresentation of students of color in physics. In our broader research, we focus our efforts on understanding how racial identity and physics identity are negotiated throughout the experiences of Black physicists. In this paper, we present a Critical Physics Identity framework that can be used to examine racialized physics identity and demonstrate the utility of this framework by analyzing interviews with four physicists. Our framework draws from prior constructs of physics identity and racialized identity and provides operational definitions of six interacting dimensions. In this paper, we present the operationalized constructs, demonstrate how we use these constructs to code narrative data, as well as outline three methods of analysis that may be applied to study systems and structures and their influences on the experiences of Black students.

Huntjens, Rafaële J C; Verschuere, Bruno; McNally, Richard J

2012-01-01

A major symptom of Dissociative Identity Disorder (DID; formerly Multiple Personality Disorder) is dissociative amnesia, the inability to recall important personal information. Only two case studies have directly addressed autobiographical memory in DID. Both provided evidence suggestive of dissociative amnesia. The aim of the current study was to objectively assess transfer of autobiographical information between identities in a larger sample of DID patients. Using a concealed information task, we assessed recognition of autobiographical details in an amnesic identity. Eleven DID patients, 27 normal controls, and 23 controls simulating DID participated. Controls and simulators were matched to patients on age, education level, and type of autobiographical memory tested. Although patients subjectively reported amnesia for the autobiographical details included in the task, the results indicated transfer of information between identities. The results call for a revision of the DID definition. The amnesia criterion should be modified to emphasize its subjective nature.

Responses to professional identity threat: Identity management strategies in incident narratives of health care professionals.

2015-01-01

The purpose of this paper is to explore sensemaking of incidents by health care professionals through an analysis of the role of professional identity in narratives of incidents. Using insights from social identity theory, the authors argue that incidents may create a threat of professional identity, and that professionals make use of identity management strategies in response to this identity threat. The paper draws on a qualitative analysis of incident narratives in 14 semi-structured interviews with physicians, nurses, and residents at a Dutch specialist hospital. The authors used an existing framework of identity management strategies to categorize the narratives. The analysis yielded two main results. First, nurses and residents employed multiple types of identity management strategies simultaneously, which points to the possible benefit of combining different strategies. Second, physicians used the strategy of patronization of other professional groups, a specific form of downward comparison. The authors discuss the implications of the findings in terms of the impact of identity management strategies on the perpetuation of hierarchical differences in health care. The authors argue that efforts to manage incident handling may profit from considering social identity processes in sensemaking of incidents. This is the first study that systematically explores how health care professionals use identity management strategies to maintain a positive professional identity in the face of incidents. This study contributes to research on interdisciplinary cooperation in health care.

Tomboy as protective identity.

PubMed

Craig, Traci; Lacroix, Jessica

2011-01-01

The tomboy in contemporary U.S. culture is a complex identity, providing meaning to many girls and women. In this article, we argue tomboy as a gendered social identity also provides temporary "protections" to girls and women in three main ways. First, tomboy identity can excuse masculine-typed behavior in girls and women and, in doing so, protect women from presumptions about sexual reputation and sexual orientation. Second, tomboy identities can provide some protection for lesbian girls and women who prefer to not divulge their sexual orientation. And, third, tomboy identity can gain women limited privilege to spaces for which masculinity is an unspoken requirement. The temporary nature of the protections provided to tomboys undermines the ability of tomboys to truly transcend the binary gender system.

2014-02-01

A renewed interest in identity as one of the core markers of personality disorders has been introduced by the DSM-5 Level of Personality Functioning Scale. However, little is known about the utility of the construct of identity in children and adolescents. This study aimed to broaden the knowledge of identity integration as a core component of personality functioning in adolescents. The authors investigated levels of identity integration, as measured by the Severity Indices of Personality Problems (SIPP-118; Verheul et al., 2008), in adolescents in both normal (n = 406) and clinical populations (n = 285). Furthermore, changes in levels of identity integration during treatment were investigated in a clinical subsample (n = 76). Levels of identity integration were not associated with age. They were, however, associated with the absence or presence of personality pathology. Most adolescents receiving inpatient psychotherapy gradually changed toward more healthy levels of identity integration; a significant number, however, remained at maladaptive levels of identity functioning after intensive psychotherapy.

Ictal single-photon emission computed tomography (SPECT) is a valuable method for localizing the ictal onset zone in the presurgical evaluation of patients with intractable epilepsy. Conventional methods used to localize the ictal onset zone have problems with time lag from seizure onset to injection. To evaluate the clinical usefulness of a method that we developed, which involves an attachable automated injector (AAI), in reducing time lag and improving the ability to localize the zone of seizure onset. Patients admitted to the epilepsy monitoring unit (EMU) between January 1, 2003, and June 30, 2008, were included. The definition of ictal onset zone was made by comprehensive review of medical records, magnetic resonance imaging (MRI), data from video electroencephalography (EEG) monitoring, and invasive EEG monitoring if available. We comprehensively evaluated the time lag to injection and the image patterns of ictal SPECT using traditional visual analysis, statistical parametric mapping-assisted, and subtraction ictal SPECT coregistered to an MRI-assisted means of analysis. Image patterns were classified as localizing, lateralizing, and nonlateralizing. The whole number of patients was 99: 48 in the conventional group and 51 in the AAI group. The mean (SD) delay time to injection from seizure onset was 12.4+/-12.0 s in the group injected by our AAI method and 40.4+/-26.3 s in the group injected by the conventional method (P=0.000). The mean delay time to injection from seizure detection was 3.2+/-2.5 s in the group injected by the AAI method and 21.4+/-9.7 s in the group injected by the conventional method (P=0.000). The AAI method was superior to the conventional method in localizing the area of seizure onset (36 out of 51 with AAI method vs. 21 out of 48 with conventional method, P=0.009), especially in non-temporal lobe epilepsy (non-TLE) patients (17 out of 27 with AAI method vs. 3 out of 13 with conventional method, P=0.041), and in lateralizing the

Tools for Understanding Identity

DOE Office of Scientific and Technical Information (OSTI.GOV)

Creese, Sadie; Gibson-Robinson, Thomas; Goldsmith, Michael

Identity attribution and enrichment is critical to many aspects of law-enforcement and intelligence gathering; this identity typically spans a number of domains in the natural-world such as biographic information (factual information – e.g. names, addresses), biometric information (e.g. fingerprints) and psychological information. In addition to these natural-world projections of identity, identity elements are projected in the cyber-world. Conversely, undesirable elements may use similar techniques to target individuals for spear-phishing attacks (or worse), and potential targets or their organizations may want to determine how to minimize the attack surface exposed. Our research has been exploring the construction of a mathematical modelmore » for identity that supports such holistic identities. The model captures the ways in which an identity is constructed through a combination of data elements (e.g. a username on a forum, an address, a telephone number). Some of these elements may allow new characteristics to be inferred, hence enriching the holistic view of the identity. An example use-case would be the inference of real names from usernames, the ‘path’ created by inferring new elements of identity is highlighted in the ‘critical information’ panel. Individual attribution exercises can be understood as paths through a number of elements. Intuitively the entire realizable ‘capability’ can be modeled as a directed graph, where the elements are nodes and the inferences are represented by links connecting one or more antecedents with a conclusion. The model can be operationalized with two levels of tool support described in this paper, the first is a working prototype, the second is expected to reach prototype by July 2013: Understanding the Model The tool allows a user to easily determine, given a particular set of inferences and attributes, which elements or inferences are of most value to an investigator (or an attacker).

Selection of tRNA(Asp) amber suppressor mutants having alanine, arginine, glutamine, and lysine identity.

Elements that confer identity to a tRNA in the cellular environment, where all aminoacyl-tRNA synthetases are competing for substrates, may be delineated by in vivo experiments using suppressor tRNAs. Here we describe the selection of active Escherichia coli tRNAAsp amber mutants and analyze their identity. Starting from a library containing randomly mutated tRNA(CUA)Asp genes, we isolated four amber suppressors presenting either lysine, alanine, or glutamine activity. Two of them, presenting mainly alanine or lysine activity, were further submitted to a second round of mutagenesis selection in order to improve their efficiency of suppression. Eleven suppressors were isolated, each containing two or three mutations. Ten presented identities of the two parental mutants, whereas one had switched from lysine to arginine identity. Analysis of the different mutants revealed (or confirmed for some nucleotides) their role as positive and/or negative determinants in AlaRS, LysRS, and ArgRS recognition. More generally, it appears that tRNAAsp presents identity characteristics closely related to those of tRNALys, as well as a structural basis for acquiring alanine or arginine identity upon moderate mutational changes; these consist of addition or suppression of the corresponding positive or negative determinants, as well as tertiary interactions. Failure to isolate aspartic acid-inserting suppressors is probably due to elimination of the important G34 identity element and its replacement by an antideterminant when changing the anticodon of the tRNAAsp to the CUA triplet.

The antifibrinolytic drug tranexamic acid was assessed in controlling bleeding in 12 patients with left-sided proctocolitis. The study was designed as a double-blind cross-over trial employing a dose of 4·5 g of tranexamic acid/day together with identical placebo. A statistically significant reduction in rectal bleeding was achieved in 50% of cases with a minimum of side effects. Sigmoidoscopic grading of rectal mucosal appearances was improved. Frequency of diarrhoea and stool consistency were not altered. Tranexamic acid may have a part to play in the management of selected patients with ulcerative colitis in whom bleeding is difficult to control with orthodox treatment. PMID:6980404

Perceived consequences of hypothetical identity-inconsistent sexual experiences: effects of perceiver's sex and sexual identity.

PubMed

Preciado, Mariana A; Johnson, Kerri L

2014-04-01

Most people organize their sexual orientation under a single sexual identity label. However, people may have sexual experiences that are inconsistent with their categorical sexual identity label. A man might identify as heterosexual but still experience some attraction to men; a woman might identify as lesbian yet enter into a romantic relationship with a man. Identity-inconsistent experiences are likely to have consequences. In the present study, we examined lay perceptions of the consequences of identity-inconsistent sexual experiences for self-perceived sexuality and for social relationships among a sexually diverse sample (N = 283). We found that the perceived consequences of identity-inconsistent experiences for self-perception, for social stigmatization, and for social relationships varied as a function of participant sex, participant sexual identity (heterosexual, gay, lesbian), and experience type (fantasy, attraction, behavior, love). We conclude that not all identity-inconsistent sexual experiences are perceived as equally consequential and that the perceived consequences of such experiences vary predictably as a function of perceiver sex and sexual identity. We discuss the role lay perceptions of the consequences of identity-inconsistent sexual experiences may play in guiding attitudes and behavior.

2016-01-01

As a part of an ongoing clinical study of refugees with post traumatic stress disorder (PTSD), the primary objective of the current study was to examine and describe the distribution of adult attachment patterns as assessed by the Adult Attachment Interview (AAI) in Arabic-speaking refugees. A total of 43 adult male and female refugees with Iraqi and Palestinian backgrounds completed the AAI. Sixty-seven percent of the sample was classified as Unresolved with respect to loss or trauma and a substantial proportion of insecure attachment representations (14% Secure-Autonomous, 39% Dismissing, 42% Preoccupied, 5% Cannot Classify) was found, in addition to high intake levels of post traumatic stress symptoms and comorbidity. Findings are compared with AAI studies of other PTSD or trauma samples, and the paper elaborates upon the methodological challenges in administering the AAI in a context of simultaneous translation.

2014-08-01

In this study, we evaluated cortical connectivity modifications by electroencephalography (EEG) lagged coherence analysis, in subjects with dissociative disorders and in controls, after retrieval of attachment memories. We asked thirteen patients with dissociative disorders and thirteen age- and sex-matched healthy controls to retrieve personal attachment-related autobiographical memories through adult attachment interviews (AAI). EEG was recorded in the closed eyes resting state before and after the AAI. EEG lagged coherence before and after AAI was compared in all subjects. In the control group, memories of attachment promoted a widespread increase in EEG connectivity, in particular in the high-frequency EEG bands. Compared to controls, dissociative patients did not show an increase in EEG connectivity after the AAI. Conclusions: These results shed light on the neurophysiology of the disintegrative effect of retrieval of traumatic attachment memories in dissociative patients.

The present study examined the relationship of perceived parental closeness and parental ethnic identity on personal ethnic identity and colorblindness beliefs in 275 part-White biracial Americans (M age = 23.88). Respondents completed online measures of their personal ethnic identity (minority, White, and multiracial), perceived parental ethnic identity, parental closeness, and attitudes about the state of race relations and the need for social action in the United States. Using path modeling, results show that part-White biracial individuals perceive their ethnic identity to be strongly linked to their parental racial identities, especially when they had closer parental relationships. Moreover, stronger minority identity was linked to less colorblind attitudes, and greater White identity was linked to greater colorblind attitudes suggesting that patterns of identity may influence how biracial individuals view race-relations and the need for social action. Implications for biracial well-being and their understanding of prejudice and discrimination are discussed. (PsycINFO Database Record (c) 2015 APA, all rights reserved).

Online Identities and Social Networking

Maheswaran, Muthucumaru; Ali, Bader; Ozguven, Hatice; Lord, Julien

Online identities play a critical role in the social web that is taking shape on the Internet. Despite many technical proposals for creating and managing online identities, none has received widespread acceptance. Design and implementation of online identities that are socially acceptable on the Internet remains an open problem. This chapter discusses the interplay between online identities and social networking. Online social networks (OSNs) are growing at a rapid pace and has millions of members in them. While the recent trend is to create explicit OSNs such as Facebook and MySpace, we also have implicit OSNs such as interaction graphs created by email and instant messaging services. Explicit OSNs allow users to create profiles and use them to project their identities on the web. There are many interesting identity related issues in the context of social networking including how OSNs help and hinder the definition of online identities.

EPOS started its Implementation Phase in October 2015 and is now actively working in order to integrate multidisciplinary data into a single e-infrastructure. Multidisciplinary data are organized and governed by the Thematic Core Services (TCS) - European wide organizations and e-Infrastructure providing community specific data and data products - and are driven by various scientific communities encompassing a wide spectrum of Earth science disciplines. TCS data, data products and services will be integrated into the Integrated Core Services (ICS) system, that will ensure their interoperability and access to these services by the scientific community as well as other users within the society. The EPOS competence center (EPOS CC) goal is to tackle two of the main challenges that the ICS are going to face in the near future, by taking advantage of the technical solutions provided by EGI. In order to do this, we will present the two pilot use cases the EGI-EPOS CC is developing: 1) The AAI pilot, dealing with the provision of transparent and homogeneous access to the ICS infrastructure to users owning different kind of credentials (e.g. eduGain, OpenID Connect, X509 certificates etc.). Here the focus is on the mechanisms which allow the credential delegation. 2) The computational pilot, Improve the back-end services of an existing application in the field of Computational Seismology, developed in the context of the EC funded project VERCE. The application allows the processing and the comparison of data resulting from the simulation of seismic wave propagation following a real earthquake and real measurements recorded by seismographs. While the simulation data is produced directly by the users and stored in a Data Management System, the observations need to be pre-staged from institutional data-services, which are maintained by the community itself.

Transsexualism and other variations of gender identity are based on a stable sense of identity. The aetiology of this phenomenon is not fully known. Suffering caused by gender dysphoria is alleviated with sex reassignment. The psychiatric assessment of both adolescents and adults has been centralized in Finland to two university hospitals, the Helsinki University Hospital and Tampere University Hospital. In both hospitals, multidisciplinary teams aim at differential diagnosis by using well-known psychiatric and psychological instruments. Wishes for sex reassignment that are caused by a mental health disorder are excluded. Assessment in adolescence is challenging because the identity in youth is still forming.

Adolescence is the specific stage during which psychological changes and identity searching are at the forefront of preoccupations. The identity construction proves to be particularly complex in a transcultural context. Starting from their clinical questioning, the authors propose a literature review of the process of identity construction in a population of adolescent children of migrant parents. This theoretical reflection is based on conceptualisations of this process in intercultural psychology, transcultural psychology and in the theory of dialogical self. Putting into perspective these different approaches and their interconnections will help better understand the reality of hybrid or half-breed identity during adolescence.

How do pre-service teachers perceive place identity, and is there a connection between their formative place identity and the development of their professional teaching identity? These questions are probed among pre-service teachers who participated in a course titled "Integrating Nature into Preschool." The design of the course was based on a multidimensional teaching model that yields a matrix of students' perceptions and the practical aspects derived from them as the students undergo a range of experiences in the course of an academic year. The profile of perceptions uses a mixed-methods analysis that presents statements attesting to four indicators of place identity: familiarity, belonging, involvement, and meaningfulness. These indicators point to a broad spectrum of perceptions arrayed on a continual time axes as well as differences in perception and its complexity. A connection between the development of place identity and that of professional teaching identity is found.

When moral identity symbolization motivates prosocial behavior: the role of recognition and moral identity internalization.

PubMed

Winterich, Karen Page; Aquino, Karl; Mittal, Vikas; Swartz, Richard

2013-09-01

This article examines the role of moral identity symbolization in motivating prosocial behaviors. We propose a 3-way interaction of moral identity symbolization, internalization, and recognition to predict prosocial behavior. When moral identity internalization is low, we hypothesize that high moral identity symbolization motivates recognized prosocial behavior due to the opportunity to present one's moral characteristics to others. In contrast, when moral identity internalization is high, prosocial behavior is motivated irrespective of the level of symbolization and recognition. Two studies provide support for this pattern examining volunteering of time. Our results provide a framework for predicting prosocial behavior by combining the 2 dimensions of moral identity with the situational factor of recognition.

Evidence for the identity and some comparative properties of alpha-ketoglutarate and 2-keto-4-hydroxyglutarate dehydrogenase activity.

PubMed

Gupta, S C; Dekker, E E

Enzyme preparations of pig heart and Escherichia coli are shown to catalyze a NAD+- and CoASH-dependent oxidation of 2-keto-4-hydroxyglutarate. Several independent lines of evidence support the conclusion that this hydroxyketo acid is a substrate for the well known alpha-ketoglutarate dehydrogenase complex of the citric acid cycle. The evidence includes (a) a constant ratio of specific activity values for the two substrates through several steps of purification, (b) identical elution profiles from a calcium phosphate gel-cellulose column and a constant ratio of specific activity toward the two substrates throughout the activity peak, (c) identical inactivation curves in controlled heat denaturation studies, (d) the same pH activity curves, (e) no effect on the oxidation of either keto acid by repeated freezing and thawing of dehydrogenase preparations, and (f) the same activity pattern when the E. coli complex is distributed into several fractions by sucrose density gradient centrifugation. Additionally, the same cofactors are required for maximal activity and glyoxylate inhibits the oxidation of either substrate noncompetitively. Ferricyanide-linked oxidation of 2-keto-4-hydroxyglutarate yields malate as the product and a 1:2:1 stoichiometric relationship is obtained between the amount of hydroxyketo acid oxidized, ferricyanide reduced, and malate formed.

The moral dimension of politicized identity: Exploring identity content during the 2012 Presidential Elections in the USA.

It is well known that politicized identities are especially good predictors of collective action, but very little is known about what these identities are. We propose that moral identity content plays a central role in politicized identities. We examined this among (un)politicized Americans in the 2012 US Presidential Elections. In a longitudinal community sample of US citizens (N = 760), we tracked personal (i.e., unique) and politicized (i.e., party activist) identity content: before, during, and after the election. We compared identity content of individuals who self-labelled as politicized (i.e., active party promoters) or unpoliticized (i.e., passive party supporters): (1) Democrats (n = 69) longitudinally and (2) Republicans (n = 69) cross-sectionally to examine three hypotheses: Moral identity content (e.g., trustworthy) would be more prominent in politicized (vs. unpoliticized) identities (H1); moral identity content overlapping politicized and personal identities predict seeing the self as politicized (H2) and engaging in party activism (H3). Results largely supported H1 and H2, but only weakly supported H3. We conclude that politicized identities are moralized identities that have a self-evaluative, but not strongly action-motivation, function. We discuss the implications of our findings and method for politicization research. © 2016 The British Psychological Society.

Synthesis oftrans-3-hexadecenoic acid and oftrans-3-hexadecenoic-1-C(14) acid.

PubMed

Knipprath, W G; Stein, R A

1966-01-01

Thetrans-3-hexadecenoic acid has been synthesized. Physical properties and chemical degradation prove its identity with the acid earlier isolated from several plant lipids. In the sequence of the synthesis, the introduction of a terminal triple bond into commercially available 1-tetradecene was performed by bromination and debromination with KOH and NaNH(2). Chain elongation by a Grignard reaction with CO(2) gave a carboxylic acid with a triple bond in the 2-position. Reduction with LiAlH(4) yielded the corresponding alcohol, and reduction of the triple to thetrans double bond was accomplished with Na in ethanol. Bromination of the alcohol with PBr(3) and conversion of the bromide to the nitrile with KCN or KC(14)N elongated the carbon chain to the desired length. Methanolysis with HCl in methanol and saponification with KOH formed the acid with acceptable yields, and in the case of the C(14)-labeled carboxyl, group, with high specific activity.

To analyse the proportions of protein identity between Zika virus and dengue, Japanese encephalitis, yellow fever, West Nile and chikungunya viruses as well as polymorphism between different Zika virus strains. We used published protein sequences for the Zika virus and obtained protein sequences for the other viruses from the National Center for Biotechnology Information (NCBI) protein database or the NCBI virus variation resource. We used BLASTP to find regions of identity between viruses. We quantified the identity between the Zika virus and each of the other viruses, as well as within-Zika virus polymorphism for all amino acid k -mers across the proteome, with k ranging from 6 to 100. We assessed accessibility of protein fragments by calculating the solvent accessible surface area for the envelope and nonstructural-1 (NS1) proteins. In total, we identified 294 Zika virus protein fragments with both low proportion of identity with other viruses and low levels of polymorphisms among Zika virus strains. The list includes protein fragments from all Zika virus proteins, except NS3. NS4A has the highest number (190 k -mers) of protein fragments on the list. We provide a candidate list of protein fragments that could be used when developing a sensitive and specific serological test to detect previous Zika virus infections.

Reciprocal Associations between Educational Identity and Vocational Identity in Adolescence: A Three-wave Longitudinal Investigation.

PubMed

Negru-Subtirica, Oana; Pop, Eleonora Ioana

2018-04-01

Education and vocation are core identity domains in adolescence. School is a normative social context in this developmental time frame and the formation of an educational identity is embedded in the goals that youth pursue in school. One of the main goals of education is to prepare young people for their future careers. Hence, educational identity should support the formation of vocational identity during adolescence. Considering the limited evidence on the longitudinal links between these two domain-specific identities, we conducted a three-wave investigation, testing the moderating role of age group, gender, and type of school. Participants (N = 1030; 59.3% female) were adolescents (M age  = 16.72 years, SD age  = 1.23, age range 14-19 years) who completed self-report measures of educational and vocational identity three times during an academic year. We underscored reciprocal associations between educational identity and vocational identity. The results indicate that strong educational commitments supported the formation of strong vocational commitments across time. Adolescents who were involved in the in-depth exploration of their educational choices also reported more vocational exploration during the school year. In turn, vocational identity processes also supported educational identity formation, especially the reconsideration of educational commitments. In terms of moderators, we underscored that vocational commitment making and vocational flexibility bolstered educational commitment only in early-to-middle adolescents. Educational in-depth exploration fostered the identification with vocational commitments only in girls. Educational reconsideration of commitment promoted vocational self-doubt only in adolescents attending work-bound high-schools. Implications for research and practice are discussed.

This study compared two forms of accountability that can be used to promote diversity and fairness in personnel selections: identity-conscious accountability (holding decision makers accountable for which groups are selected) versus identity-blind accountability (holding decision makers accountable for making fair selections). In a simulated application screening process, undergraduate participants (majority female) sorted applicants under conditions of identity-conscious accountability, identity-blind accountability, or no accountability for an applicant pool in which white males either did or did not have a human capital advantage. Under identity-conscious accountability, participants exhibited pro-female and pro-minority bias, particularly in the white-male-advantage applicant pool. Under identity-blind accountability, participants exhibited no biases and candidate qualifications dominated interview recommendations. Participants exhibited greater resentment toward management under identity-conscious accountability. PMID:26660723

Animal-Assisted Intervention for trauma: a systematic literature review.

2015-01-01

Animals have a long history of inclusion in psychiatric treatment. There has been a recent growth in the empirical study of this practice, known as Animal-Assisted Intervention (AAI). We conducted a systematic review of the empirical literature on AAI for trauma, including posttraumatic stress disorder (PTSD). Ten studies qualified for inclusion, including six peer-reviewed journal articles and four unpublished theses. Participants were predominantly survivors of child abuse, in addition to military veterans. The presentation of AAI was highly variable across the studies. The most common animal species were dogs and horses. The most prevalent outcomes were reduced depression, PTSD symptoms, and anxiety. There was a low level of methodological rigor in most studies, indicating the preliminary nature of this area of investigation. We conclude that AAI may provide promise as a complementary treatment option for trauma, but that further research is essential to establish feasibility, efficacy, and manualizable protocols.

Gender identity development in adolescence.

2013-07-01

This article is part of a Special Issue "Puberty and Adolescence".This article aims to provide an outline of what is currently known on trajectories, and contributing factors to gender identity development in adolescence. We give a historical overview of the concept of gender identity, and describe general identity development in adolescence, gender identity development in the general population and in gender variant youth. Possible psychosocial (such as child and parental characteristics) and biological factors (such as the effects of prenatal exposure to gonadal hormones and the role of genetics) contributing to a gender variant identity are discussed. Studies focusing on a number of psychosocial and biological factors separately, indicate that each of these factors influence gender identity formation, but little is known about the complex interplay between the factors, nor about the way individuals themselves contribute to the process. Research into normative and gender variant identity development of adolescents is clearly lagging behind. However, studies on persons with gender dysphoria and disorders of sex development, show that the period of adolescence, with its changing social environment and the onset of physical puberty, seems to be crucial for the development of a non-normative gender identity.

We have reported a inhibitor of acid lipases in liver lysosomes and erythrocytes from chickens [M. Fujii et al., Int. J. Biochem., 22, 895-898 (1990)]. In this paper, the properties of the inhibitor were described in comparison with those of apo A-I of chicken. The purified inhibitor migrated with the same mobility on SDS-PAGE as apo A-I, and had a molecular weight of 27,000. The peptide map from the lipase inhibitor was similar to that of apo A-I. Antibodies to the acid lipase inhibitor also reacted with apo A-I. Apo A-I inhibited the acid lipase activities of liver lysosomes and erythrocytes from chickens as strongly as the lipase inhibitor. The N-terminal amino acid sequence of lipase inhibitor was identical to that of apo A-I as far as residue 20. The amino acid sequence of peptides obtained from the inhibitor by cleavage with CNBr corresponded to internal sequence of apo A-I, and so the CNBr-peptides were derived by cleavage after the methionine residues in apo A-I. The findings showed that the inhibitor of the acid lipases in liver lysosomes and erythrocytes from chickens was identical to apo A-I.

Although the AAI pacing mode has been shown to be electromechanically superior to the DDD pacing mode in sick sinus syndrome (SSS), there is evidence suggesting that during AAI pacing the presence of natural ventricular activation pattern is not enough for hemodynamic benefit to occur. Myocardial performance index (MPI) is a simply measurable Doppler-derived index of combined systolic and diastolic myocardial performance. The aim of this study was to investigate whether AAI pacing mode is electromechanically superior to the DDD mode in patients with SSS by using Doppler-derived MPI. Thirty-nine SSS patients with dual-chamber pacing devices were evaluated by using Doppler echocardiography in AAI mode and DDD mode. The optimal atrioventricular (AV) interval in DDD mode was determined and atrial stimulus-R interval was measured in AAI mode. The ratio of the atrial stimulus-R interval to the optimal AV interval was defined as relative AV interval (rAVI) and the ratio of MPI in AAI mode to that in DDD mode was defined as relative MPI (rMPI). The rMPI was significantly correlated with atrial stimulus-R interval and rAVI (r = 0.57, P = 0.0002, and r = 0.67, P < 0.0001, respectively). A cutoff point of 1.73 for rAVI provided optimum sensitivity and specificity for rMPI >1 based on the receiver operator curves. Even though the intrinsic AV conduction is moderately prolonged, some SSS patients with dual-chamber pacing devices benefit from the ventricular pacing with optimal AV interval. MPI is useful to determine the optimal pacing mode in acute experiment.

Religiosity as identity: toward an understanding of religion from a social identity perspective.

PubMed

Ysseldyk, Renate; Matheson, Kimberly; Anisman, Hymie

2010-02-01

As a social identity anchored in a system of guiding beliefs and symbols, religion ought to serve a uniquely powerful function in shaping psychological and social processes. Religious identification offers a distinctive "sacred" worldview and "eternal" group membership, unmatched by identification with other social groups. Thus, religiosity might be explained, at least partially, by the marked cognitive and emotional value that religious group membership provides. The uniqueness of a positive social group, grounded in a belief system that offers epistemological and ontological certainty, lends religious identity a twofold advantage for the promotion of well-being. However, that uniqueness may have equally negative impacts when religious identity itself is threatened through intergroup conflict. Such consequences are illustrated by an examination of identities ranging from religious fundamentalism to atheism. Consideration of religion's dual function as a social identity and a belief system may facilitate greater understanding of the variability in its importance across individuals and groups.

John Locke speaks of personal identity and survival of consciousness after death. A criterion of personal identity through time is given. Such a criterion specifies, insofar as that is possible, the necessary and sufficient conditions for the survival of persons. John Locke holds that personal identity is a matter of psychological continuity. He considered personal identity (or the self) to be founded on consciousness (viz. memory), and not on the substance of either the soul or the body.

The theory of planned behaviour: self-identity, social identity and group norms.

PubMed

Terry, D J; Hogg, M A; White, K M

1999-09-01

The aim of the present study was to examine further the role that self-identity plays in the theory of planned behaviour and, more specifically, to: (1) examine the combined effects of self-identity and social identity constructs on intention and behaviour, and (2) examine the effects of self-identity as a function of past experience of performing the behaviour. The study was concerned with the prediction of intention to engage in household recycling and reported recycling behaviour. A sample of 143 community residents participated in the study. It was prospective in design: measures of the predictors and intention were obtained at the first wave of data collection, whereas behaviour was assessed two weeks later. Self-identity significantly predicted behavioural intention, a relationship that was not dependent on the extent to which the behaviour had been performed in the past. As expected, there was also evidence that the perceived norm of a behaviourally relevant reference group was related to behavioural intention, but only for participants who identified strongly with the group, whereas the relationship between perceived behavioural control (a personal factor) and intention was strongest for low identifiers.

When dual identity becomes a liability: identity and political radicalism among migrants.

PubMed

Simon, Bernd; Reichert, Frank; Grabow, Olga

2013-03-01

This article examines the role of dual identity in political radicalism among migrants. Dual identity is defined as identification with both one's ethnocultural minority in-group and one's society of residence. We employed a longitudinal research design using members of the two largest migrant groups in Germany (Turkish migrants and Russian migrants) as participants. We reasoned that when dual identity is burdened with incompatibility between component identifications, it may foster controversial or even destructive forms of political mobilization, such as radicalism. Multiple regression analysis controlling for other influences confirmed the hypothesized moderated relationship between dual identification and sympathy for radical action. When accompanied by high, as opposed to low, perceived identity incompatibility, dual identification predicted increases in sympathy for radical action among both Turkish migrants and Russian migrants. The implications for public life in ethnically and culturally heterogeneous societies are discussed.

Anthropology, HIV and contingent identities.

PubMed

Gatter, P N

1995-12-01

The paper explores the relationship between social identity and HIV/AIDS, with special reference to gay men in Britain. This relationship was first seen as significant since it might have a bearing on the spread of HIV in the population. Three major forms of commentary have emerged on the issue: (i) basic research into the relationship between sexual identities and behaviours; (ii) applied research on how to convert the findings from (i) into health promotional materials, and (iii) discourse from within the politically gay community on what HIV/AIDS means for gay people. These different forms of commentary arise from a diverse range of voices, within and outside academia. The paper draws comparison between different disciplinary approaches to questions of identity and HIV/AIDS, in terms of their relative strengths and weaknesses (for example, contrasting psychology with anthropology). An ethnography of a day centre for people living with HIV/AIDS is used to illustrate the need to understand identity from a processual perspective, so that both individual and collective identities are seen as emerging from specific historical circumstances and struggles. A dialogic approach to understanding identity, tied to qualitative empirical research, is suggested as necessary to understanding how different forms of identity engage with HIV/AIDS (gender, ethnicity, age, sexual orientation), and how the identities of individuals and groups are always complex, shifting mosaics.

Gender identity disorder (GID) results from a disagreement between a person's biological sex and the gender to which he or she identifies. With respect to the treatment of female to male GID, testosterone replacement therapy (TRT) is available. The uric acid (UA) level can be influenced by testosterone; however, the early effects and dose-dependency of TRT on the serum UA concentration have not been evaluated in this population. We herein conducted a dose-response analysis of TRT in 160 patients with female to male GID. The TRT consisted of three treatment groups who received intramuscular injections of testosterone enanthate: 125 mg every two weeks, 250 mg every three weeks and 250 mg every two weeks. Consequently, serum UA elevation was observed after three months of TRT and there was a tendency toward testosterone dose-dependency. The onset of hyperuricemia was more prevalent in the group who received the higher dose. We also demonstrated a positive correlation between increased levels of serum UA and serum creatinine. Since the level of serum creatinine represents an individual's muscle volume and the muscle is a major source of purine, which induces UA upregulation, the serum UA elevation observed during TRT is at least partially attributed to an increase in muscle mass. This is the first study showing an association between serum UA elevation and a TRT-induced increase in muscle mass. The current study provides important information regarding TRT for the follow-up and management of the serum UA levels in GID patients.

Human Rights and the Excess of Identity

PubMed Central

Al Tamimi, Yussef

2017-01-01

Identity is a central theme in contemporary politics, but legal academia lacks a rigorous analysis of this concept. The aim of this article is twofold: (i) firstly, it aims to reveal presumptions on identity in human rights law by mapping how the European Court of Human Rights approaches identity and (ii) secondly, it seeks to analyse these presumptions using theoretical insights on identity. By merging legal and theoretical analysis, this article contributes a reading of the Court’s case law which suggests that the tension between the political and apolitical is visible as a common thread in the Court’s use of identity. In case law concerning paternity, the Court appears to hold a specific view of what is presented as an unquestionable part of identity. This ostensibly pre-political notion of identity becomes untenable in cases where the nature of an identity feature, such as the headscarf, is contended or a minority has adopted a national identity that conflicts with the majoritarian national identity. The Court’s approach to identity in such cases reflects a paradox that is inherent to identity; identity is personal while simultaneously constituted and shaped by overarching power mechanisms.

We previously reported chromatographic evidence supporting the similarity of yellow chromophores isolated from aged human lens proteins, early brunescent cataract lens proteins and calf lens proteins ascorbylated in vitro [Cheng, R. et al. Biochimica et Biophysica Acta 1537, 14-26, 2001]. In this paper, new evidence supporting the chemical identity of the modified amino acids in these protein populations were collected by using a newly developed two-dimensional LC-MS mapping technique supported by tandem mass analysis of the major species. The pooled water-insoluble proteins from aged normal human lenses, early stage brunescent cataract lenses and calf lens proteins reacted with or without 20 mM ascorbic acid in air for 4 weeks were digested with a battery of proteolytic enzymes under argon to release the modified amino acids. Aliquots equivalent to 2.0 g of digested protein were subjected to size-exclusion chromatography on a Bio-Gel P-2 column and four major A330nm-absorbing peaks were collected. Peaks 1, 2 and 3, which contained most of the modified amino acids were concentrated and subjected to RP-HPLC/ESI-MS, and the mass elution maps were determined. The samples were again analyzed and those peaks with a 10(4) - 10(6) response factor were subjected to MS/MS analysis to identify the daughter ions of each modification. Mass spectrometric maps of peaks 1, 2 and 3 from cataract lenses showed 58, 40 and 55 mass values, respectively, ranging from 150 to 600 Da. Similar analyses of the peaks from digests of the ascorbylated calf lens proteins gave 81, 70 and 67 mass values, respectively, of which 100 were identical to the peaks in the cataract lens proteins. A total of 40 of the major species from each digest were analyzed by LC-MS/MS and 36 were shown to be identical. Calf lens proteins incubated without ascorbic acid showed several similar mass values, but the response factors were 100 to 1000-fold less for every modification. Based upon these data, we conclude

Developing a workable teacher identity: Building and negotiating identity within a professional network

NASA Astrophysics Data System (ADS)

Rostock, Roseanne

The challenge of attracting and retaining the next generation of teachers who are skilled and committed to meeting the growing demands of the profession is of increasing concern to researchers and policy makers, particularly since 45--50% of beginning teachers leave the profession within five years (Ingersoll & Smith, 2003). Reasons for such attrition include compensation, status and working conditions; however, there is growing evidence that a critical factor in new teacher retention hinges on teachers' ability to accomplish the difficult task of forming a workable professional identity in the midst of competing discourses about teaching (Alsup, 2006; Britzman, 2003). There is little research on professional identity development among those beginning teachers at highest risk for attrition (secondary math and science teachers, and those with strong academic backgrounds). This study explores the professional identity development of early-career math and science teachers who are part of the Knowles Science Teaching Foundation's (KSTF) teaching fellowship program, an external support network that aims to address many of the issues leading to high attrition among this particular population of teachers. Using narrative research methods, I examine three case studies of beginning teachers, exploring how they construct professional identity in relation to various discourse communities and negotiate tensions across multiple discourses. The cases identify both dominant discourses and counter-discourses that the teachers draw upon for important identity development resources. They also demonstrate that the way a teacher manages tensions across competing discourses is important to how well one can negotiate a workable professional identity. In particular, they emphasize the importance of engaging in borderland discourses (Gee, 1996) as a way of taking agency in one's own identity development as well as in transforming one's discourse communities. These cases shed light on how

Using data from a national survey of college students in introductory English courses (on science-related experiences, particularly in high school), we examine the influence of students' physics and math identities on their choice to pursue a physics career. Males have higher math and physics identities than females in all three dimensions of our identity framework. These dimensions include: performance/competence (perceptions of ability to perform/understand), recognition (perception of recognition by others), and interest (desire to learn more). A regression model predicting students' intentions to pursue physics careers shows, as expected, that males are significantly more likely to choose physics than females. Surprisingly, however, when physics and math identity are included in the model, females are shown to be equally likely to choose physics careers as compared to males.

Animal-Assisted Intervention for trauma: a systematic literature review

Animals have a long history of inclusion in psychiatric treatment. There has been a recent growth in the empirical study of this practice, known as Animal-Assisted Intervention (AAI). We conducted a systematic review of the empirical literature on AAI for trauma, including posttraumatic stress disorder (PTSD). Ten studies qualified for inclusion, including six peer-reviewed journal articles and four unpublished theses. Participants were predominantly survivors of child abuse, in addition to military veterans. The presentation of AAI was highly variable across the studies. The most common animal species were dogs and horses. The most prevalent outcomes were reduced depression, PTSD symptoms, and anxiety. There was a low level of methodological rigor in most studies, indicating the preliminary nature of this area of investigation. We conclude that AAI may provide promise as a complementary treatment option for trauma, but that further research is essential to establish feasibility, efficacy, and manualizable protocols.

Science Identity in Informal Education

NASA Astrophysics Data System (ADS)

Schon, Jennifer A.

The national drive to increase the number of students pursuing Science Technology, Engineering, and Math (STEM) careers has brought science identity into focus for educators, with the need to determine what encourages students to pursue and persist in STEM careers. Science identity, the degree to which students think someone like them could be a scientist is a potential indicator of students pursuing and persisting in STEM related fields. Science identity, as defined by Carlone and Johnson (2007) consists of three constructs: competence, performance, and recognition. Students need to feel like they are good at science, can perform it well, and that others recognize them for these achievements in order to develop a science identity. These constructs can be bolstered by student visitation to informal education centers. Informal education centers, such as outdoor science schools, museums, and various learning centers can have a positive impact on how students view themselves as scientists by exposing them to novel and unique learning opportunities unavailable in their school. Specifically, the University of Idaho's McCall Outdoor Science School (MOSS) focuses on providing K-12 students with the opportunity to learn about science with a place-based, hands-on, inquiry-based curriculum that hopes to foster science identity development. To understand the constructs that lead to science identity formation and the impact the MOSS program has on science identity development, several questions were explored examining how students define the constructs and if the MOSS program impacted how they rate themselves within each construct. A mixed-method research approach was used consisting of focus group interviews with students and pre, post, one-month posttests for visiting students to look at change in science identity over time. Results from confirmatory factor analysis indicate that the instrument created is a good fit for examining science identity and the associated

Identities, social representations and critical thinking

López-Facal, Ramón; Jiménez-Aleixandre, María Pilar

2009-09-01

This comment on L. Simonneaux and J. Simonneaux paper focuses on the role of identities in dealing with socio-scientific issues. We argue that there are two types of identities (social representations) influencing the students' positions: On the one hand their social representations of the bears' and wolves' identities as belonging to particular countries (Slovenia versus France for bears, France and Italy for wolves), in other words, as having national identities; on the other hand representations of their own identities as belonging to the field of agricultural practitioners, and so sharing this socio-professional identity with shepherds and breeders, as opposed to ecologists. We discuss how these representations of identities influenced students' reasoning and argumentation, blocking in some cases the evaluation of evidence. Implications for developing critical thinking and for dealing with SSI in the classrooms are outlined.

Distinctive acceptor-end structure and other determinants of Escherichia coli tRNAPro identity.

PubMed Central

McClain, W H; Schneider, J; Gabriel, K

1994-01-01

The previously uncharacterized determinants of the specificity of tRNAPro for aminoacylation (tRNAPro identity) were defined by a computer comparison of all Escherichia coli tRNA sequences and tested by a functional analysis of amber suppressor tRNAs in vivo. We determined the amino acid specificity of tRNA by sequencing a suppressed protein and the aminoacylation efficiency of tRNA by examining the steady-state level of aminoacyl-tRNA. On substituting nucleotides derived from the acceptor end and variable pocket of tRNAPro for the corresponding nucleotides in a tRNAPhe gene, the identity of the resulting tRNA changed substantially but incompletely to that of tRNAPro. The redesigned tRNAPhe was weakly active and aminoacyl-tRNA was not detected. Ethyl methanesulfonate mutagenesis of the redesigned tRNAPhe gene produced a mutant with a wobble pair in place of a base pair in the end of the acceptor-stem helix of the transcribed tRNA. This mutant exhibited both a tRNAPro identity and substantial aminoacyl-tRNA. The results speak for the importance of a distinctive conformation in the acceptor-stem helix of tRNAPro for aminoacylation by the prolyl-tRNA synthetase. The anticodon also contributes to tRNAPro identity but is not necessary in vivo. Images PMID:8127693

Our research to discover potential new multitarget agents led to the synthesis of 10 novel derivatives of cinnamic acids and propranolol, atenolol, 1-adamantanol, naphth-1-ol, and (benzylamino) ethan-1-ol. The synthesized molecules were evaluated as trypsin, lipoxygenase and lipid peroxidation inhibitors and for their cytotoxicity. Compound 2b derived from phenoxyphenyl cinnamic acid and propranolol showed the highest lipoxygenase (LOX) inhibition (IC 50 = 6 μΜ) and antiproteolytic activity (IC 50 = 0.425 μΜ). The conjugate 1a of simple cinnamic acid with propranolol showed the higher antiproteolytic activity (IC 50 = 0.315 μΜ) and good LOX inhibitory activity (IC 50 = 66 μΜ). Compounds 3a and 3b , derived from methoxylated caffeic acid present a promising combination of in vitro inhibitory and antioxidative activities. The S isomer of 2b also presented an interesting multitarget biological profile in vitro . Molecular docking studies point to the fact that the theoretical results for LOX-inhibitor binding are identical to those from preliminary in vitro study.

Social identity and worldview validation: the effects of ingroup identity primes and mortality salience on value endorsement.

PubMed

Halloran, Michael J; Kashima, Emiko S

2004-07-01

In this article, the authors report an investigation of the relationship between terror management and social identity processes by testing for the effects of social identity salience on worldview validation. Two studies, with distinct populations, were conducted to test the hypothesis that mortality salience would lead to worldview validation of values related to a salient social identity. In Study 1, reasonable support for this hypothesis was found with bicultural Aboriginal Australian participants (N = 97). It was found that thoughts of death led participants to validate ingroup and reject outgroup values depending on the social identity that had been made salient. In Study 2, when their student and Australian identities were primed, respectively, Anglo-Australian students (N = 119) validated values related to those identities, exclusively. The implications of the findings for identity-based worldview validation are discussed.

The high prevalence, severity, and prematurity of coronary artery disease (CAD) in the Indian population cannot be completely explained by the conventional lipid parameters and the existing lipid indices. To calculate newly defined advanced atherogenic index (AAI) in premature CAD patients and compare it between cases and controls and Correlate its values with the existing indices. One hundred and twenty premature CAD patients and an equal number of age and sex matched healthy individuals were included in this study. Lipid profile and nonconventional lipid parameters like oxidized Low density lipoprotein (OX LDL), small dense LDL (SD LDL), lipoprotein (a) apolipoprotein B (Apo B), and apolipoprotein A1 (Apo A1) were estimated and their values were used to define AAI and existing lipid indices like AI, lipid tetrad index (LTI) and lipid pentad index (LPI). The mean age of cases and controls was 37.29 + 4.50 and 36.13 + 3.53 years, respectively. The value of AAI was highly significant in cases (3461.22 ± 45.20) as compared to controls (305.84 ± 21.80). AAI has shown better statistical significance and correlation (P < 0.0001, r = 0.737) as compared to the earlier indices such as AI (P < 0.01, r = 0.52), LTI (P < 0.001, r = 0.677) and LPI (P < 0.001, r = 0.622) in premature CAD. Kolmogorov D statistic and cumulative distribution function plot has shown that AAI can discriminate cases and controls more accurately as compared to the earlier indices. Statistically AAI appears to be a better marker of consolidated lipid risk in premature CAD patients as compared to the earlier indices.

Eudaimonistic identity theory posits a link between activity and identity, where a self-defining activity promotes the strength of a person’s identity. An activity engaged in with high enjoyment, full involvement, and high concentration can facilitate the subjective experience of flow. In the present paper, we hypothesized in accordance with the theory of psychological selection that beyond the promotion of individual development and complexity at the personal level, the relationship between flow and identity at the social level is also positive through participation in self-defining activities. Three different samples (i.e., American, Chinese, and Spanish) filled in measures for flow and social identity, with reference to four previously self-reported activities, characterized by four different combinations of skills (low vs. high) and challenges (low vs. high). Findings indicated that flow was positively associated with social identity across each of the above samples, regardless of participants’ gender and age. The results have implications for increasing social identity via participation in self-defining group activities that could facilitate flow. PMID:26924995

Stories we live, identities we build: how are elementary teachers' science identities shaped by their lived experiences?

2018-02-01

The aim of this multiple case study was to uncover a series of critical events and experiences related to the formation of the science identities of four beginning elementary female teachers, through a life-history approach and a conceptualization of teacher identity as lived experience. Grounded within the theoretical framework of Figured Worlds, the study used qualitative, interpretive methods for data collection (interviews, biographies, teaching philosophies) and analysis. The analysis shed light on the ways in which various experiences situated within different Figured Worlds (science, family and childhood, schooling, out-of-school, university, professional) impacted the participants' identity trajectories. The findings provided three main insights that contribute to science identity research and have implications for elementary teacher preparation: (a) science teacher identity is multidimensional and extends beyond cognitive domains of becoming to include affective dimensions; (b) science teacher identity is relational, linked and shaped by various other constructs or sub-identities; (c) place and time, defined as a space with meaning created by experiences, and science teacher identity are inextricably bound to one another.

Procedural memory in dissociative identity disorder: when can inter-identity amnesia be truly established?

PubMed

Huntjens, Rafaële J C; Postma, Albert; Woertman, Liesbeth; van der Hart, Onno; Peters, Madelon L

2005-06-01

In a serial reaction time task, procedural memory was examined in Dissociative Identity Disorder (DID). Thirty-one DID patients were tested for inter-identity transfer of procedural learning and their memory performance was compared with 25 normal controls and 25 controls instructed to simulate DID. Results of patients seemed to indicate a pattern of inter-identity amnesia. Simulators, however, were able to mimic a pattern of inter-identity amnesia, rendering the results of patients impossible to interpret as either a pattern of amnesia or a pattern of simulation. It is argued that studies not including DID-simulators or simulation-free memory tasks, should not be taken as evidence for (or against) amnesia in DID.

Identity-based motivation: Implications for intervention

PubMed Central

Oyserman, Daphna; Destin, Mesmin

2010-01-01

Children want to succeed academically and attend college, but their actual attainment often lags behind; some groups (e.g., boys, low-income children) are particularly likely to experience this gap. Social structural factors matter, influencing this gap in part by affecting children's perceptions of what is possible for them and people like them in the future. Interventions that focus on this macro-micro interface can boost children's attainment. We articulate the processes underlying these effects using an integrative culturally sensitive framework entitled identity-based motivation (IBM, Oyserman, 2007, 2009a, 2009b). The IBM model assumes that identities are dynamically constructed in context. People interpret situations and difficulties in ways that are congruent with currently active identities and prefer identity-congruent to identity-incongruent actions. When action feels identity-congruent, experienced difficulty highlights that the behavior is important and meaningful. When action feels identity-incongruent, the same difficulty suggests that the behavior is pointless and “not for people like me.” PMID:21516204

Moral identity and emotion in athletes.

Kavussanu, Maria; Willoughby, Adrian; Ring, Christopher

2012-12-01

The purpose of this study was to investigate the effects of moral identity on physiological responses to affective pictures, namely, the startle blink reflex and pain-related evoked potential. Male (n = 48) and female (n = 46) athletes participating in contact team sports were randomly assigned to either a moral identity group or a non-moral identity group and viewed a series of unpleasant, neutral, and pleasant sport-specific pictures. During picture viewing, a noxious electrocutaneous stimulus was delivered as the startle probe and the startle blink and pain-related evoked potential were measured. Upon completion of physiological measures, participants reviewed the pictures and rated them for valence and arousal. ANOVAs revealed that participants in the moral identity group displayed larger startle blinks and smaller pain-related potentials than did those in the non-moral identity group across all picture valence categories. However, the difference in the magnitude of startle blinks between the moral and non-moral identity groups was larger in response to unpleasant than pleasant and neutral pictures. Our findings suggest that moral identity affects physiological responses to sport-specific affective pictures, thereby providing objective evidence for the link between moral identity and emotion in athletes.

The emergence, structure and development of ethnic identity during childhood: the case of Roma identity.

PubMed

Pnevmatikos, Dimitris; Geka, Maria; Divane, Maria

2010-12-01

This study investigates the emergence, development and structure of ethnic identity during childhood. Forty Roma children living in Greece aged between 2.8 and 11.9 years answered questions about their awareness/recognition of four aspects of their ethnic identity-namely place of habitation, traditional costumes, the Roma language, and early betrothal of children-their identity and their sense of stability and constancy. The study also investigates how the children feel about the abandonment of those four aspects. The evidence from the current data supports the hypothesis that awareness of ethnic identity emerges before the age of 4. Moreover, this study offers direct empirical evidence of the multidimensionality of ethnic identity. A model of three concentric rings is proposed, extending from a core containing the most highly valued aspects of ethnic identity to the outer annulus that comprises the nonpermanent and nonstable aspects of ethnic identity. The aspects in each annulus differ in terms of the development of the sense of stability and constancy and the feelings associated with loss of the aspects in question. Even the youngest participants considered the aspects in the core to be stable and constant as well as emotionally charged; and even the 11-year-olds did not consider the aspects contained in the outer, more fluid annulus as stable and constant aspects of their ethnic identity. The development of an aspect is determined by what the majority of adults in a society, at a particular time in history, consider to be most important.

Intergroup Leadership Across Distinct Subgroups and Identities.

Rast, David E; Hogg, Michael A; van Knippenberg, Daan

2018-03-01

Resolving intergroup conflict is a significant and often arduous leadership challenge, yet existing theory and research rarely, if ever, discuss or examine this situation. Leaders confront a significant challenge when they provide leadership across deep divisions between distinct subgroups defined by self-contained identities-The challenge is to avoid provoking subgroup identity distinctiveness threat. Drawing on intergroup leadership theory, three studies were conducted to test the core hypothesis that, where identity threat exists, leaders promoting an intergroup relational identity will be better evaluated and are more effective than leaders promoting a collective identity; in the absence of threat, leaders promoting a collective identity will prevail. Studies 1 and 2 ( N = 170; N = 120) supported this general proposition. Study 3 ( N = 136) extended these findings, showing that leaders promoting an intergroup relational identity, but not a collective identity, improved intergroup attitudes when participants experienced an identity distinctiveness threat.

Fingerprint Recognition with Identical Twin Fingerprints

Fingerprint recognition with identical twins is a challenging task due to the closest genetics-based relationship existing in the identical twins. Several pioneers have analyzed the similarity between twins' fingerprints. In this work we continue to investigate the topic of the similarity of identical twin fingerprints. Our study was tested based on a large identical twin fingerprint database that contains 83 twin pairs, 4 fingers per individual and six impressions per finger: 3984 (83*2*4*6) images. Compared to the previous work, our contributions are summarized as follows: (1) Two state-of-the-art fingerprint identification methods: P071 and VeriFinger 6.1 were used, rather than one fingerprint identification method in previous studies. (2) Six impressions per finger were captured, rather than just one impression, which makes the genuine distribution of matching scores more realistic. (3) A larger sample (83 pairs) was collected. (4) A novel statistical analysis, which aims at showing the probability distribution of the fingerprint types for the corresponding fingers of identical twins which have same fingerprint type, has been conducted. (5) A novel analysis, which aims at showing which finger from identical twins has higher probability of having same fingerprint type, has been conducted. Our results showed that: (a) A state-of-the-art automatic fingerprint verification system can distinguish identical twins without drastic degradation in performance. (b) The chance that the fingerprints have the same type from identical twins is 0.7440, comparing to 0.3215 from non-identical twins. (c) For the corresponding fingers of identical twins which have same fingerprint type, the probability distribution of five major fingerprint types is similar to the probability distribution for all the fingers' fingerprint type. (d) For each of four fingers of identical twins, the probability of having same fingerprint type is similar. PMID:22558204

Chlamydophila pneumoniae and Mycoplasma pneumoniae are associated with acute exacerbation of bronchial asthma (AEBA). The aim of this study was to evaluate the correlation between these acute bacterial infections and the severity of AEBA. We prospectively analysed consecutive patients admitted to the Emergency Department with acute asthma exacerbation. In every patient peak expiratory flow (PEF) measurement was performed on admission, and spirometry during follow-up. Serology for Chlamydophila and Mycoplasma pneumoniae was performed on admission and after 4-8 weeks. Fifty-eight patients completed the study. Acute atypical infections (AAI) was observed in 22/58 cases; we found single acute C. pneumoniae in 19 cases, single acute M. pneumoniae in 2 cases, and double acute infection in one case. Functional impairment on admission was greater in patients with AAI than in patients without AAI (PEF 205 +/- 104 L/min vs 276 +/- 117 p = 0.02) and persisted until visit 2 (FEV1% 76.30 +/- 24.54 vs FEV1% 92.91 +/- 13.89, p = 0.002). Moreover, the proportion of patients who presented with severe AEBA was significantly greater in the group with AAI than in the group without AAI (15/22 vs 12/36, p = 0.01; OR 4.29, 95% CI 1.38-13.32). Our data suggest an association between acute atypical infection and a more severe AEBA.

Māori are the indigenous peoples of New Zealand. However, the term 'Māori' can refer to a wide range of people of varying ethnic compositions and cultural identity. We present a statistical model identifying 6 distinct types, or 'Māori Identity Signatures,' and estimate their proportion in the Māori population. The model is tested using a Latent Profile Analysis of a national probability sample of 686 Māori drawn from the New Zealand Attitudes and Values Study. We identify 6 distinct signatures: Traditional Essentialists (22.6%), Traditional Inclusives (16%), High Moderates (31.7%), Low Moderates (18.7%), Spiritually Orientated (4.1%), and Disassociated (6.9%). These distinct Identity Signatures predicted variation in deprivation, age, mixed-ethnic affiliation, and religion. This research presents the first formal statistical model assessing how people's identity as Māori is psychologically structured, documents the relative proportion of these different patterns of structures, and shows that these patterns reliably predict differences in core demographics. We identify a range of patterns of Māori identity far more diverse than has been previously proposed based on qualitative data, and also show that the majority of Māori fit a moderate or traditional identity pattern. The application of our model for studying Māori health and identity development is discussed. (c) 2015 APA, all rights reserved).

Identity change and informed consent

PubMed Central

Witt, Karsten

2017-01-01

In this paper, I focus on a kind of medical intervention that is at the same time fascinating and disturbing: identity-changing interventions. My guiding question is how such interventions can be ethically justified within the bounds of contemporary bioethical mainstream that places great weight on the patient's informed consent. The answer that is standardly given today is that patients should be informed about the identity effects, thus suggesting that changes in identity can be treated like ‘normal’ side effects. In the paper, I argue that this approach is seriously lacking because it misses important complexities going along with decisions involving identity changes and consequently runs into mistakes. As a remedy I propose a new approach, the ‘perspective-sensitive account’, which avoids these mistakes and thus provides the conceptual resources to systematically reflect on and give a valid consent to identity-changing interventions.

Smoking-related self-identity processes are important for smoking cessation. We examined whether quitter self-identity (i.e. identification with quitting smoking) could be strengthened through a writing exercise, and whether expected social support for quitting, manipulated through vignettes, could facilitate identification with quitting. Participants (N = 339 daily smokers) were randomly assigned to a 2 (identity: strengthened quitter self-identity vs. control) × 3 (social support: present vs. absent vs. neutral control) between-participants design. The main outcome was post-test quitter self-identity. Post-test quitter self-identity was not strengthened successfully. Only a small and marginally significant intervention effect was found on quitter self-identity, which did not generalise to positively influence quit-intention or behaviour. The social support manipulation did not facilitate quitter self-identity. Secondary content analyses showed that quitter self-identity was strengthened among participants who linked quitting smoking to their lifestyle, wanted to become quitters for health reasons, and whose reasons for becoming quitters included approach of positive aspects of quitting, but not among participants who linked quitter self-identity to their self-perceptions. Results provide insight into the content of smokers' self-conceptualizations as quitters. Writing exercises should be improved and tested to eventually successfully strengthen quitter identities.

Formation of amino acids by cobalt-60 irradiation of hydrogen cyanide solutions

Sweeney, M. A.; Toste, A. P.; Ponnamperuma, C.

1976-01-01

Experiments were conducted to study the pathway for the prebiotic origin of amino acids from hydrogen cyanide (HCN) under the action of ionizing radiation considered as an effective source of energy on the primitive earth. The irradiations were performed in a cobalt-60 source with a dose rate of 200,000 rad/hr. Seven naturally occurring amino acids are identified among the products formed by the hydrolysis of gamma-irradiated solutions of HCN: glycine, alanine, valine, serine, threonine, aspartic acid, and glutamic acid. The identity of these amino acids is established by gas chromatography and mass spectrometry. Control experiments provided evidence that the amino acids are not the result of contamination.

Perceived parenting dimensions and identity styles: exploring the socialization of adolescents' processing of identity-relevant information.

Smits, Ilse; Soenens, Bart; Luyckx, Koen; Duriez, Bart; Berzonsky, Michael; Goossens, Luc

2008-04-01

This study examined the relationships between crucial dimensions of perceived parenting (support, behavioral control, and psychological control) and the three identity styles defined by Berzonsky [Berzonsky, M. D. (1990). Self-construction over the life span: A process perspective on identity formation. Advances in Personal Construct Psychology, 1, 155-186.]. Each identity style was hypothesized to relate to a specific pattern of perceived parenting dimensions. Hypotheses were examined in a sample of middle and late adolescents (n=674). An information-oriented style was positively predicted by parental support. Contrary to expectations, however, an information-oriented style was also positively predicted by psychological control. A normative identity style was positively predicted by support and behavioral control. In line with expectations, a diffuse-avoidant identity style was positively predicted by psychological control and negatively by maternal (but not paternal) behavioral control. Findings are discussed in light of the literature on the socialization of identity formation and directions for future research are outlined.

Yang, Chia-Chen; Holden, Sean M; Carter, Mollie D K

2018-01-11

Social comparison on social media has received increasing attention, but most research has focused on one type of social comparison and its psycho-emotional implications. Little is known about how different types of social comparison influence youth's identity development. Drawing on the theories of identity processing styles and social comparison, we examined how two different forms of social comparison on social media related to three identity processing styles, which in turn predicted youth's global self-esteem and identity clarity. We surveyed 219 college freshmen (M age  = 18.29; 74% female) once in the Fall and once in the Spring. Social comparison of ability on social media was related to concurrent diffuse-avoidant identity processing style, which predicted lower identity clarity months later. In contrast, social comparison of opinion on social media did not influence college freshmen's global self-esteem and identity clarity through identity processing styles. The findings clarified the implications of online social comparison for youth's identity development.

To evaluate the risk of incident physical disability and the decline in gait speed over a 6-year follow-up associated with a low ankle-arm index (AAI) in older adults. Observational cohort study. Forsyth County, North Carolina; Sacramento County, California; Washington County, Maryland; and Allegheny County, Pennsylvania. Four thousand seven hundred five older adults, 58% women and 17.6% black, participating in the Cardiovascular Health Study. AAI was measured in 1992/93 (baseline). Self-reported mobility, activity of daily living (ADL), and instrumental activity of daily living (IADL) disability and gait speed were recorded at baseline and at 1-year intervals over 6 years of follow-up. Mobility disability was defined as any difficulty walking half a mile and ADL and IADL disability was defined as any difficulty with 11 specific ADL and IADL tasks. Individuals with mobility, ADL, or IADL disability at baseline were excluded from the respective incident disability analyses. Lower baseline AAI values were associated with increased risk of mobility disability and ADL/IADL disability. Clinical cardiovascular disease (CVD), diabetes mellitus, and interim CVD events partially explained these associations for mobility disability and clinical CVD and diabetes mellitus partially explained these associations for ADL and IADL disability. Individuals with an AAI less than 0.9 had on average a mean decrease in gait speed of 0.02 m/s per year, or a decline of 0.12 m/s over the 6-year follow-up. Prevalent CVD partly explained this decrease but interim CVD events did not further attenuate it. Low AAI serves as marker of future disability risk. Reduction of disability risk in patients with a low AAI should consider cardiovascular comorbidity and the prevention of additional disabling CVD events.

Matsushima, Rumi; Ozaki, Hitomi

2015-08-01

This study examined university students' academic motivation, focusing on individual differences in their sense of identity. The participants were 109 female Japanese students from two private universities (age range = 19-22 yr., M = 19.3, SD = 0.6). They completed four scales: the Multidimensional Ego Identity Scale, the Scale of Students' Attitude Toward Their Classes, the Academic Motivation Inventory, and the Scale of Lecture Self-Evaluation. Correlational analyses assessed the relationships between subscales. Then, path analysis was conducted to evaluate whether sense of identity affected attitude toward classes, academic motivation, and lecture self-evaluation. Differences particularly in psychosocial identity and self-identity accounted for significant variance in the students' attitudes toward classes, academic motivation, and lecture self-evaluation.

The bile acids derived from [4-14-C]cholesterol administered intracardially to rats with cannulated bile ducts were identified and quantitated. Over a period of 28 days about 90% of the administered 14-C was found in bile of which 73% was retained in the biliary acid fraction. [7beta-3-H]cholic acid, alpha-muri[3beta-3-H]cholic acid, beta-muri[3beta-3-H]cholic acid and litho[3beta-3-H]cholic acid were prepared with specific activities of about 30 muCi/mg by reduction of appropriate ketonic precursors with NaB3H4 and were added to the biliary acid fraction. After separation and purification of the bile acids, cholic, chenodeoxycholic, alpha- and beta-muricholic acids accounted for 70, 16, 7.5 and 6.1%, respectively, of the 14-C in the biliary acid fraction. The specific activities of these isolated 14-C-labeled acids were almost identical. Lithocholic acid accounted for a maximum of 0.2% and ursodeoxycholic acid and 7-oxolithocholic acid could account for no more than 2% of the biliary 14-C. Gas-liquid chromatography on 3% OV-17 of the trimethylsilyl ether derivatives of the methyl esters of the common bile acids of rat bile results in their complete separation and provides a convenient means of estimating the relative proportions of these acids in rat bile. By this method, the relative amounts of the four major acids, cholic, chenodeoxycholic, alpha- and beta-muricholic acids were 63, 20, 8 and 6%, respectively.

Infant attachment, adult attachment, and maternal sensitivity: revisiting the intergenerational transmission gap.

PubMed

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.

Adaptation of the Utrecht-Management of Identity Commitments Scale (U-MICS) to the measurement of the parental identity domain.

PubMed

Piotrowski, Konrad

2018-04-01

The present studies examined the psychometric properties of the Utrecht-Management of Identity Commitments Scale (U-MICS) adapted to the measurement of identity formation in the parental identity domain. As the parental identity domain has only been studied within the neo-Eriksonian approach to a very limited extent, the aim of these studies was to prepare a short, valid and reliable tool for the measurement of parental identity in order to fill this gap. The associations of commitment, in-depth exploration and reconsideration of commitment in the parental domain with well-being and with other identity constructs were analyzed. The results showed that parental identity formation is associated with mothers' satisfaction with life and trait anxiety and with identity formation in other areas as well. The initial results suggest that the adapted version of the U-MICS is a valid and reliable measure that can be used in future studies on parental identity formation. © 2017 The Author.

Headspace volatiles from 52 oak species advertise induction, species identity, and evolution, but not defense.

PubMed

Pearse, Ian S; Gee, Wai S; Beck, John J

2013-01-01

Leaf volatiles convey information about a plant to other organisms in their proximity. Despite increasing interest in understanding the relevance of volatile emissions for particular ecological interactions, there has been relatively little effort to assess generally what information volatile profiles transmit. We surveyed the volatile profiles of wounded and unwounded leaves of 52 oak (Quercus) species. We used phylogenetic comparison and multivariate techniques to assess in what circumstances oak individuals advertised their species identity, evolutionary history, direct defenses, or damage. We found that both species identity and evolutionary history were advertised when leaves were wounded, but species could not be differentiated by odor when leaves were not wounded. Various fatty-acid derivative compounds showed the strongest phylogenetic signal suggesting that they may best disclose taxonomic affiliations in oaks. We tested whether oak volatile composition or diversity advertised high defensive investment, but we found no evidence for this. Wounded leaves disclose much about an oak species' identity and taxonomic affiliation, but unwounded leaves do not. This is consistent with the idea that volatile information is targeted toward natural enemy recruitment.

Sport-Related Identities and the "Toxic Jock"

PubMed

Miller, Kathleen E

2009-01-01

Little attention has been paid to the multidimensional nature of athletic involvement, which includes identity formation as well as participation in sports activities. Five hundred eighty-one sport-involved undergraduate students completed a questionnaire assessing their sport-related identities, goal orientations, primary sport ratings, and conformity to masculine norms. F-tested mean comparisons and hierarchical linear regressions were used to explore the characteristics associated with two distinct sport-related identities ("athletes" and "jocks"). Jock identity was associated with an ego-oriented approach to sports (men only), whereas athlete identity was associated with a task-oriented approach (both genders). Jock identity was positively associated with conformity to masculine norms, particularly for men, whereas athlete identity was positively associated with some masculine norms (i.e., Winning) and negatively associated with others (i.e., Playboy). These findings help to identify the correlates of a "toxic Jock" identity that may signal elevated risk for health-compromising behavior.

Human Rights and the Excess of Identity: A Legal and Theoretical Inquiry into the Notion of Identity in Strasbourg Case Law.

PubMed

Al Tamimi, Yussef

2018-06-01

Identity is a central theme in contemporary politics, but legal academia lacks a rigorous analysis of this concept. The aim of this article is twofold: (i) firstly, it aims to reveal presumptions on identity in human rights law by mapping how the European Court of Human Rights approaches identity and (ii) secondly, it seeks to analyse these presumptions using theoretical insights on identity. By merging legal and theoretical analysis, this article contributes a reading of the Court's case law which suggests that the tension between the political and apolitical is visible as a common thread in the Court's use of identity. In case law concerning paternity, the Court appears to hold a specific view of what is presented as an unquestionable part of identity. This ostensibly pre-political notion of identity becomes untenable in cases where the nature of an identity feature, such as the headscarf, is contended or a minority has adopted a national identity that conflicts with the majoritarian national identity. The Court's approach to identity in such cases reflects a paradox that is inherent to identity; identity is personal while simultaneously constituted and shaped by overarching power mechanisms.

South Asian women: identities and conflicts.

PubMed

Inman, Arpana G

2006-04-01

This study investigated the effects of education, level of religiosity, ethnic identity (internal and external), and racial identity statuses (conformity, dissonance, resistance, and awareness) on cultural value conflict for first and second generation South Asian women (N = 193). Cultural value conflict was examined in two areas, intimate relations and sex-role expectations. Results revealed that level of religiosity was more predictive of intimate relations conflict for second generation than first generation women. Furthermore, higher ratings in internal ethnic identity predicted greater intimate relations conflict in first generation women, while both internal and external ethnic identity predicted intimate relations conflict in second generation women. Finally, higher dissonance scores in racial identity predicted greater conflicts in sex-role expectations for second generation women alone.

[Asymmetric effect of in-group social values on identity with common-identity and common-bond in-groups].

PubMed

Nakashima, Ken'ichiro; Isobe, Chikae; Toshihiko, Souma; Ura, Mitsuhiro

2013-06-01

Moderating effects of group type on the relationship between in-group social values and group identity were investigated. Previous research has indicated that values attached to the in-group, such as its status, privileges, and power, lead to increased group identity. However, these studies have not investigated the role of the type of in-groups on this effect. We conducted an experiment that manipulated the in-group type. In the common-identity type of in-group condition, formation of in- and out-groups on the basis of social categorization was established. In the common-bond type of in-group condition, interactions between the group members were conducted. Results indicated that in the former condition, the degree of in-group social values affected group identity; however, this effect was not found in the latter condition. These results suggest that social values of the in-group have an asymmetric effect on group identity, depending upon the in-group type as a common-identity or common-bond group.

Xingnaojing Injection (XNJI) is a modern Chinese formula came from famous Chinese medicine An Gong Niu Huang Pill. XNJI has been used for treatment of cerebral diseases and stroke in China, and is approved by the State Food and Drug Administration of China for the treatment of acute alcohol intoxication (AAI). XNJI belongs to the ethnopharmacological family of medicines. In this study, we investigated the mechanisms of the XNJI effect on AAI. To investigate the effects of XNJI on glutamate, gamma-aminobutyric acid (GABA) and related receptor in lateral hypothalamic area (LHA) of AAI rat. Adult male Sprague-Dawley rats were implanted with microdialysis probes in LHA. Rats were randomly divided into control, model, 1.36mg/kg XNJI, 0.68mg/kg XNJI and 0.34mg/kg XNJI groups. During microdialysis, baseline samples were collected from 1h to 2.5h; thereafter, the rats were given an intraperitoneal injection of 52% ethanol, 5.2g/kg, or saline for control group. Twenty minutes later, three doses of XNJI was given by unilateral injection respectively, while saline for control and model groups, and samples were collected for the next 4h. The extracellular glutamate and GABA levels were measured in the LHA by a high performance liquid chromatography coupled with fluorescence detector (HPLC-FLU). The expression levels of related receptors N-methyl-d-aspartate receptor (NR) subunit NR2A, NR2B and GABAA were analyzed by reverse transcription polymerase chain reaction (RT-PCR). Ethanol (5.2g/kg) significantly decreased the extracellular levels of glutamate and increased extracellular GABA in LHA. On the other hand ethanol significantly decreased NR2A and NR2B mRNAs expression, and increase GABAA mRNA expression. XNJI could increase the extracellular level of glutamate and decrease that of GABA; moreover, induced an increase in NR2A and NR2B mRNA expression, and a decrease in GABAA mRNA expression in LHA. The current changes in glutamate, GABA and mRNA expressions of related

The roles of identity formation and moral identity in college student mental health, health-risk behaviors, and psychological well-being.

This study examined the roles of identity formation and moral identity in predicting college student mental health (anxiety and depressive symptoms), health-risk behaviors (hazardous alcohol use and sexual risk taking), and psychological well-being (self-esteem and meaning). The sample comprised 9,500 college students (aged 18-25 years, mean = 19.78, standard deviation = 1.61; 73% female; 62% European American), from 31 different universities, who completed an online self-report survey. Structural equation models found that identity maturity (commitment making and identity synthesis) predicted 5 of the health outcomes (except sexual risk taking), and moral identity predicted all of the health outcomes. In most cases identity maturity and moral identity also interacted in predicting mental health and psychological well-being, but not health-risk behaviors. The maturity and specific contents of identity may both play unique and often interactive roles in predicting college student health. Thus, college student health might be bolstered by helping them establish appropriate identity commitments. © 2012 Wiley Periodicals, Inc.

Career identity in the veterinary profession.

PubMed

Page-Jones, S; Abbey, G

2015-04-25

This research investigates vet and vet nurse career identity through the qualitative methodology of narrative enquiry. It derives learning and understanding from these empirical data to assist the veterinary profession to adjust to the changing industry landscape. Through a case series of 20 vets and vet nurses' career stories, this paper seeks understanding about career identity and its impact on individuals and organisations in the light of industry consolidation. Findings suggest that career is central to identity for many veterinary professionals who tend to have a strong sense of self; this is particularly evident around self as learner and technically competent, teacher and educator, ethical and moral and dedicated and resilient. Consequently, mismatches between 'who I am' and 'what I do' tend not to lead to identity customisation (to fit self into role or organisation) but to the search for alternative, more identity-compatible employment. This study offers a valuable insight for employers, veterinary professionals and universities. It suggests that businesses can gain competitive advantage and employees achieve validation and enrichment by working towards organisational and individual identity congruence and that teaching veterinary professionals with contemporary business in mind may develop graduates with a more sustainable identity.

2008-01-01

Background Chlamydophila pneumoniae and Mycoplasma pneumoniae are associated with acute exacerbation of bronchial asthma (AEBA). The aim of this study was to evaluate the correlation between these acute bacterial infections and the severity of AEBA. Methods We prospectively analysed consecutive patients admitted to the Emergency Department with acute asthma exacerbation. In every patient peak expiratory flow (PEF) measurement was performed on admission, and spirometry during follow-up. Serology for Chlamydophila and Mycoplasma pneumoniae was performed on admission and after 4–8 weeks. Results Fifty-eight patients completed the study. Acute atypical infections (AAI) was observed in 22/58 cases; we found single acute C. pneumoniae in 19 cases, single acute M. pneumoniae in 2 cases, and double acute infection in one case. Functional impairment on admission was greater in patients with AAI than in patients without AAI (PEF 205 ± 104 L/min vs 276 ± 117 p = 0.02) and persisted until visit 2 (FEV1% 76.30 ± 24.54 vs FEV1% 92.91 ± 13.89, p = 0.002). Moreover, the proportion of patients who presented with severe AEBA was significantly greater in the group with AAI than in the group without AAI (15/22 vs 12/36, p = 0.01; OR 4.29, 95% CI 1.38–13.32). Conclusion Our data suggest an association between acute atypical infection and a more severe AEBA. PMID:18513407

MULTIRESIDUE DETERMINATION OF ACIDIC PESTICIDES ...

EPA Pesticide Factsheets

A multiresidue pesticide methodology has been studied and results for acidics are reported here with base/neutral to follow. This work studies a literature procedure as a possible general approach to many pesticides and potentially other analytes that are considered to be liquid chromatographic candidates rather than gas chromatographic ones. The analysis of thesewage effluent of a major southwestern US city serves as an example of the application of the methodology to a real sample. Recovery studies were also conducted to validate the proposed extraction step. A gradient elution program was followed for the high performance liquid chromatography leading to a general approach for acidics. Confirmation of identity was by EI GC/MS after conversion of the acids to the methyl ester (or other appropriate methylation) by means of trimethylsilyldiazomethane. The 3,4-dichlorophenoxyacetic acid was used as an internal standard to monitor the reaction and PCB #19 was used for the quantitation internal standard. Although others have reported similar analyses of acids, conversion to the methyl ester was by means of diazomethane itself rather than by the more convenient and safer trimethylsilyldiazomethane. Thus, the present paper supports the use of trimethylsilyldiazomethane with all of these acids (trimethylsilyldiazomethane has been used in environmental work with some phenoxyacetic acid herbicides) and further supports the usefulness of this reagent as a potential re

Preparation, crystallization and preliminary X-ray diffraction analysis of two intestinal fatty-acid binding proteins in the presence of 11-(dansylamino)undecanoic acid

Fatty-acid binding proteins (FABPs) are abundantly expressed proteins that bind a range of lipophilic molecules. They have been implicated in the import and intracellular distribution of their ligands and have been linked with metabolic and inflammatory responses in the cells in which they are expressed. Despite their high sequence identity, human intestinal FABP (hIFABP) and rat intestinal FABP (rIFABP) bind some ligands with different affinities. In order to address the structural basis of this differential binding, diffraction-quality crystals have been obtained of hIFABP and rIFABP in complex with the fluorescent fatty-acid analogue 11-(dansylamino)undecanoic acid.

Biracial Japanese American identity: an evolving process.

PubMed

Collins, J F

2000-05-01

This qualitative study explored the complexity of biracial identity development in Japanese Americans. It is based on the constant comparable method of analysis, or grounded theory. The study focused on how Japanese Americans perceived themselves in relation to other individuals, groups, and their environment. The data consisted of 15 extensive semistructured interviews with 8 men and 7 women (ages 20 to 40 years), each with 1 Japanese parent and 1 non-Asian parent. Findings relate to participants' initiating explorations of identity and perseverance in pursuing a biracial identity, which depended on the degree of support or negative experience within their social networks. Participants explored identity options attempting to develop their own meaning of identity, to develop a confident sense of themselves, and to secure a positive ethnic identity. Identity development among participants varied. It was a long-term process involving changes in the individual-environment relationship, which differed in the way individual participants influenced or selected from environmental opportunities, even creating or recreating some aspects. Within a given setting, as youths, the potential for social experiences were relatively fixed and changed only gradually. As adults, there were opportunities for participants to select their own social and geographic settings, providing opportunity for change. In their new environments, participants were exposed to new contacts and role models, acquired new behavioral repertoire, and underwent role transitions. Depending on this, new and different aspects of biracial identity developed. Participants indicated it was an emotional and conflictual process to positive assertion of identity. Before reaching this, all of the participants experienced periods of confusion. Most asserted biracial identity gradually, through a process of racial identity development consisting of the individual's changing or maintaining certain reference group

Animal-Assisted Interventions in Dutch Nursing Homes: A Survey.

Schuurmans, Lonneke; Enders-Slegers, Marie-Jose; Verheggen, Theo; Schols, Jos

2016-07-01

Animal-assisted interventions (AAI) have become more and more popular in nursing homes in the past decade. Various initiatives for using animals in nursing homes have been developed over the years (eg, animal visiting programs, residential companion animals, petting zoos) and, on the whole, the number of nursing homes that refuse animals on their premises has declined. In this survey, we aimed to determine how many Dutch nursing homes offer AAIs, what type of interventions are used, and with what aim. We also focus on the use of underlying health, hygiene, and (animal) safety protocols. Using an online Dutch nursing home database, we invited all listed (457) nursing home organizations in the Netherlands (encompassing a total of 804 nursing home locations) to participate in our digital survey, powered by SurveyMonkey. The survey consisted of a total of 45 questions, divided into general questions about the use of animals in interventions; the targeted client population(s); and specific questions about goals, guidelines, and protocols. The results were analyzed with SPSS Statistics. In the end, 244 surveys, representing 165 organizations, were returned: 125 nursing homes used AAI in one way or another, 40 did not. Nursing homes that did not offer AAI cited allergy and hygiene concerns as the most important reasons. Most nursing homes offering AAI used visiting animals, mostly dogs (108) or rabbits (76). A smaller number of nursing homes had resident animals, either living on the ward or in a meadow outside. Almost all programs involved animal-assisted activities with a recreational purpose; none of the participating nursing homes provided animal assisted therapy with therapeutic goals. Psychogeriatric patients were most frequently invited to participate. A total of 88 nursing homes used alternatives when animals were not an option or not available. The most popular alternative was the use of stuffed animals (83) followed by FurReal Friends robotic toys (14). The

The origin of KPC is unknown. The aim of this study was to detect progenitors of KPC in silico and to functionally verify their β-lactam hydrolysis activity. The sequence of KPC-2 was used to mine the NCBI protein sequence database. The best non-KPC hits were analysed by amino acid (aa) alignment and phylogenetic tree construction. Genes encoding KPC-2 homologues were expressed in Escherichia coli. The carbapenemase activities of the recombinant strains were characterized by the CarbaNP test and UV spectrophotometry and MICs of selected β-lactams were determined. Genes encoding the closest KPC-2 homologues were identified on the chromosome of Chromobacterium piscinae strain ND17 (CRP-1, 76% aa identity), Chromobacterium sp. C-61 (CRS-1, 70% aa identity) and Chromobacterium haemolyticum DSM19808 (CRH-1, 69% aa identity). All three Chromobacterium β-lactamases were phylogenetically more related to KPC than to other Ambler class A β-lactamases. The 27 bp region preceding the start codon of blaCRP-1 displayed high nucleotide identity to the corresponding region upstream from blaKPC (74%). Heterologous expression of blaCRP-1 and to a lesser extent of blaCRH-1 in E. coli significantly increased the MICs of meropenem and most cephalosporins. The CarbaNP test was positive for both recombinant strains, but spectrophotometric analysis confirmed higher carbapenemase activity for CRP-1-producing clones. The recovery of three class A β-lactamases with up to 76% aa identity to KPC from distinct Chromobacterium species is highly indicative of the role played by this genus in the evolution of KPC. © The Author 2016.

Further Conceptualizing Ethnic and Racial Identity Research: The Social Identity Approach and Its Dynamic Model.

PubMed

Verkuyten, Maykel

2016-11-01

This article proposes a further conceptualization of ethnic and racial identity (ERI) as a fundamental topic in developmental research. Adding to important recent efforts to conceptually integrate and synthesize this field, it is argued that ERI research will be enhanced by more fully considering the implications of the social identity approach. These implications include (a) the conceptualization of social identity, (b) the importance of identity motives, (c) systematic ways for theorizing and examining the critical role of situational and societal contexts, and (d) a dynamic model of the relation between ERI and context. These implications have not been fully considered in the developmental literature but offer important possibilities for moving the field forward in new directions. © 2016 The Author.

Recognizing Moral Identity as a Cultural Construct.

PubMed

Jia, Fanli; Krettenauer, Tobias

2017-01-01

Current research on moral identity shows that moral identity predicts moral action in Western cultures but not in non-Western cultures. The present paper argues that this may be due to the fact that the concept of moral identity is culturally biased. In order to remedy this situation, we argue that researchers should broaden their scopes of inquiry by adding a cultural lens to their studies of moral identity. This change is important because although some concept of moral identity likely exists in all cultures, it may function in different ways and at different levels in each place. We propose that moral identity is a context-dependent construct tied to varying social and cultural obligations. We argue that Western moral identity stresses an individually oriented morality, whereas, people from Eastern cultures consider a highly moral person to be societally oriented. We conclude by discussing the implications of this view for future research.

A considerable amount of methane produced during decomposition of landfill waste can be oxidized in landfill cover soil by methane-oxidizing bacteria (methanotrophs) thus reducing greenhouse gas emissions to the atmosphere. The identity of active methanotrophs in Roscommon landfill cover soil, a slightly acidic peat soil, was assessed by DNA-stable isotope probing (SIP). Landfill cover soil slurries were incubated with (13)C-labelled methane and under either nutrient-rich nitrate mineral salt medium or water. The identity of active methanotrophs was revealed by analysis of (13)C-labelled DNA fractions. The diversity of functional genes (pmoA and mmoX) and 16S rRNA genes was analyzed using clone libraries, microarrays and denaturing gradient gel electrophoresis. 16S rRNA gene analysis revealed that the cover soil was mainly dominated by Type II methanotrophs closely related to the genera Methylocella and Methylocapsa and to Methylocystis species. These results were supported by analysis of mmoX genes in (13)C-DNA. Analysis of pmoA gene diversity indicated that a significant proportion of active bacteria were also closely related to the Type I methanotrophs, Methylobacter and Methylomonas species. Environmental conditions in the slightly acidic peat soil from Roscommon landfill cover allow establishment of both Type I and Type II methanotrophs.

How Places Shape Identity: The Origins of Distinctive LBQ Identities in Four Small U.S. Cities.

PubMed

Brown-Saracino, Japonica

2015-07-01

Tools from the study of neighborhood effects, place distinction, and regional identity are employed in an ethnography of four small cities with growing populations of lesbian, bisexual, and queer-identified (LBQ) women to explain why orientations to sexual identity are relatively constant within each site, despite informants' within-city demographic heterogeneity, but vary substantially across the sites, despite common place-based attributes. The author introduces the concept of "sexual identity cultures"--and reveals the defining role of cities in shaping their contours. She finds that LBQ numbers and acceptance, place narratives, and newcomers' encounters with local social attributes serve as touchstones. The article looks beyond major categorical differences (e.g., urban/rural) to understand how and why identities evolve and vary and to reveal the fundamental interplay of demographic, cultural, and other city features previously thought isolatable. The findings challenge notions of identity as fixed and emphasize the degree to which self-understanding and group understanding remain collective accomplishments.

Trace identities and their semiclassical implications

NASA Astrophysics Data System (ADS)

Smilansky, Uzy

2000-03-01

The compatibility of the semiclassical quantization of area-preserving maps with some exact identities which follow from the unitarity of the quantum evolution operator is discussed. The quantum identities involve relations between traces of powers of the evolution operator. For classically integrable maps, the semiclassical approximation is shown to be compatible with the trace identities. This is done by the identification of stationary phase manifolds which give the main contributions to the result. The compatibility of the semiclassical quantization with the trace identities demonstrates the crucial importance of non-diagonal contributions. The same technique is not applicable for chaotic maps, and the compatibility of the semiclassical theory in this case remains unsettled. However, the trace identities are applied to maps which appear naturally in the theory of quantum graphs, revealing some features of the periodic orbit theory for these paradigms of quantum chaos.

Smoker Identity Development among Adolescents who Smoke

Adolescents who smoke are more likely to escalate their smoking frequency if they believe smoking is self-defining. Knowing factors that are associated with development of a smoker identity among adolescents who smoke may help to identify who will become a regular smoker. We investigated whether smoker identity development is associated with internal and external motives for smoking. For comparison, we also investigated whether social smoker identity development is associated with internal and external motives for smoking. Adolescents who smoke (n = 292) completed measures of smoker and social smoker identity, internal motives for smoking (negative affect coping, positive affect enhancement), and external motives for smoking (social fit) at baseline, 6-, 15-, and 24-month assessments of an ongoing longitudinal study of smoking patterns. We examined whether change in smoker and social smoker identity from 6 to 24 months was associated with change in motives at earlier assessment waves. We also explored whether gender moderated these relationships. Increases in negative affect coping motives were associated with smoker identity development among both males and females. Increases in social motives were associated with smoker identity development among males, and increases in negative affect coping motives were associated with social smoker identity development among females. Smoker and social smoker identities are signaled by negative affect coping as well as social motives for smoking. PMID:27136374

Lee, Debbiesiu L; Ahn, Soyeon

2013-01-01

This meta-analysis synthesized the results of 27 studies examining the relations of racial identity, ethnic identity, and racial socialization to discrimination-distress for Black Americans. The purpose was to uncover which constructs connected to racial identity, ethnic identity, and racial socialization most strongly correlate with racial discrimination and psychological distress. Discrimination significantly related to aspects of racial identity, including immersion-emersion, public regard, encounter, Afrocentricity/racial centrality/private regard, and internalization. Distress significantly correlated with preencounter/assimilation, encounter, public regard, immersion-emersion, and Afrocentricity/racial centrality/private regard. Several of these relationships were significantly moderated by the measure of racial identity or demographic variables (gender or age). Implications of these findings are discussed.

The career planning, athletic identity, and student role identity of intercollegiate student athletes.

Lally, Patricia S; Kerr, Gretchen A

2005-09-01

The purpose of this study was to examine the career planning of university student athletes and relationships between their career planning and athletic and student role identities. Two retrospective in-depth interviews were held with four male and four female university student athletes. Participants entered university with vague or nonexistent career objectives and invested heavily in their athletic roles. In the latter years of their college career, the participants discarded their sport career ambitions and allowed the student role to become more prominent in their identity hierarchies. The current findings support Brown and Hartley's (1998) suggestion that student athletes may invest in both the athlete and student role identities simultaneously and that investing in the latter may permit the exploration of nonsport career options.

Apicobasal domain identities of expanding tubular membranes depend on glycosphingolipid biosynthesis.

Metazoan internal organs are assembled from polarized tubular epithelia that must set aside an apical membrane domain as a lumenal surface. In a global Caenorhabditis elegans tubulogenesis screen, interference with several distinct fatty-acid-biosynthetic enzymes transformed a contiguous central intestinal lumen into multiple ectopic lumens. We show that multiple-lumen formation is caused by apicobasal polarity conversion, and demonstrate that in situ modulation of lipid biosynthesis is sufficient to reversibly switch apical domain identities on growing membranes of single post-mitotic cells, shifting lumen positions. Follow-on targeted lipid-biosynthesis pathway screens and functional genetic assays were designed to identify a putative single causative lipid species. They demonstrate that fatty-acid biosynthesis affects polarity through sphingolipid synthesis, and reveal ceramide glucosyltransferases (CGTs) as end-point biosynthetic enzymes in this pathway. Our findings identify glycosphingolipids, CGT products and obligate membrane lipids, as critical determinants of in vivo polarity and indicate that they sort new components to the expanding apical membrane.

2013-01-01

Many people have concealable stigmatized identities: Identities that can be hidden from others and that are socially devalued and negatively stereotyped. Understanding how these concealable stigmatized identities affect psychological well-being is critical. We present our model of the components of concealable stigmatized identities including valenced content – internalized stigma, experienced discrimination, anticipated stigma, disclosure reactions, and counter-stereotypic/positive information – and magnitude – centrality and salience. Research has shown that negatively valenced content is related to increased psychological distress. However, smaller identity magnitude may buffer this distress. We review the research available and discuss important areas for future work. PMID:23730326

This paper aims to present a perspective to better understand corporate identity through examining the perceptions of Turkish patients and develop a corporate visual identity scale. While there is no study related to corporate identity research on hospitals in Turkey as a developing country, understanding consumer's perceptions about corporate identity efforts of hospitals could provide different perspectives for recruiters. When the hospitals are considered in two different groups as university and state hospitals, the priority of the characteristics of corporate visual identity may change, whereas the top five characteristics remain the same for all the hospitals.

Tracking moving identities: after attending the right location, the identity does not come for free.

PubMed

Pinto, Yaïr; Scholte, H Steven; Lamme, V A F

2012-01-01

Although tracking identical moving objects has been studied since the 1980's, only recently the study into tracking moving objects with distinct identities has started (referred to as Multiple Identity Tracking, MIT). So far, only behavioral studies into MIT have been undertaken. These studies have left a fundamental question regarding MIT unanswered, is MIT a one-stage or a two-stage process? According to the one-stage model, after a location has been attended, the identity is released without effort. However, according to the two-stage model, there are two effortful stages in MIT, attending to a location, and attending to the identity of the object at that location. In the current study we investigated this question by measuring brain activity in response to tracking familiar and unfamiliar targets. Familiarity is known to automate effortful processes, so if attention to identify the object is needed, this should become easier. However, if no such attention is needed, familiarity can only affect other processes (such as memory for the target set). Our results revealed that on unfamiliar trials neural activity was higher in both attentional networks, and visual identification networks. These results suggest that familiarity in MIT automates attentional identification processes, thus suggesting that attentional identification is needed in MIT. This then would imply that MIT is essentially a two-stage process, since after attending the location, the identity does not seem to come for free.

Whole body acid-base modeling revisited.

PubMed

Ring, Troels; Nielsen, Søren

2017-04-01

The textbook account of whole body acid-base balance in terms of endogenous acid production, renal net acid excretion, and gastrointestinal alkali absorption, which is the only comprehensive model around, has never been applied in clinical practice or been formally validated. To improve understanding of acid-base modeling, we managed to write up this conventional model as an expression solely on urine chemistry. Renal net acid excretion and endogenous acid production were already formulated in terms of urine chemistry, and we could from the literature also see gastrointestinal alkali absorption in terms of urine excretions. With a few assumptions it was possible to see that this expression of net acid balance was arithmetically identical to minus urine charge, whereby under the development of acidosis, urine was predicted to acquire a net negative charge. The literature already mentions unexplained negative urine charges so we scrutinized a series of seminal papers and confirmed empirically the theoretical prediction that observed urine charge did acquire negative charge as acidosis developed. Hence, we can conclude that the conventional model is problematic since it predicts what is physiologically impossible. Therefore, we need a new model for whole body acid-base balance, which does not have impossible implications. Furthermore, new experimental studies are needed to account for charge imbalance in urine under development of acidosis. Copyright © 2017 the American Physiological Society.

Common Amino Acid Subsequences in a Universal Proteome—Relevance for Food Science

PubMed Central

Minkiewicz, Piotr; Darewicz, Małgorzata; Iwaniak, Anna; Sokołowska, Jolanta; Starowicz, Piotr; Bucholska, Justyna; Hrynkiewicz, Monika

2015-01-01

A common subsequence is a fragment of the amino acid chain that occurs in more than one protein. Common subsequences may be an object of interest for food scientists as biologically active peptides, epitopes, and/or protein markers that are used in comparative proteomics. An individual bioactive fragment, in particular the shortest fragment containing two or three amino acid residues, may occur in many protein sequences. An individual linear epitope may also be present in multiple sequences of precursor proteins. Although recent recommendations for prediction of allergenicity and cross-reactivity include not only sequence identity, but also similarities in secondary and tertiary structures surrounding the common fragment, local sequence identity may be used to screen protein sequence databases for potential allergens in silico. The main weakness of the screening process is that it overlooks allergens and cross-reactivity cases without identical fragments corresponding to linear epitopes. A single peptide may also serve as a marker of a group of allergens that belong to the same family and, possibly, reveal cross-reactivity. This review article discusses the benefits for food scientists that follow from the common subsequences concept. PMID:26340620

1999-01-01

Fatty acid and sterol analysis were performed on Phytomonas serpens and Phytomonas sp. grown in chemically defined and complex medium, and P. françai cultivated in complex medium. The three species of the genus Phytomonas had qualitatively identical fatty acid patterns. Oleic, linoleic, and linolenic were the major unsaturated fatty acids. Miristic and stearic were the major saturated fatty acids. Ergosterol was the only sterol isolated from Phytmonas sp. and P. serpens grown in a sterol-free medium, indicating that it was synthesized de novo. When P. françai that does not grow in defined medium was cultivated in a complex medium, cholesterol was the only sterol detected. The fatty acids and sterol isolated from Phytomonas sp. and P. serpens grown in a chemically defined lipid-free medium indicated that they were able to biosynthesize fatty acids and ergosterol from acetate or from acetate precursors such as glucose or threonine.

Who Adopts Queer and Pansexual Sexual Identities?

2017-09-01

Some nonheterosexual individuals are eschewing lesbian/gay and bisexual identities for queer and pansexual identities. The present study aimed to examine the sexual and demographic characteristics of nonheterosexual individuals who adopt these labels. A convenience sample of 2,220 nonheterosexual (1,459 lesbian/gay, 413 bisexual, 168 queer, 146 pansexual, and 34 other "write-in") individuals were recruited for a cross-sectional online survey. In support of our hypotheses, those adopting pansexual identities were younger than those adopting lesbian, gay, and bisexual identities, and those adopting queer and pansexual identities were more likely to be noncisgender than cisgender, and more likely to be cisgender women than men. The majority of pansexual individuals demonstrated sexual orientation indices within the bisexual range, and showed equivalent patterns of sexual attraction, romantic attraction, sexual behavior, and partner gender as bisexual-identified men and women. In contrast, three-quarters of queer men, and more than half of queer women, reported sexual attraction in the homosexual range. This study found that rather than a general movement toward nontraditional sexual identities, queer and pansexual identities appear most appealing to nonheterosexual women and noncisgender individuals. These findings contribute important information regarding who adopts queer and pansexual identities in contemporary sexual minority populations.

Altered self-identity and autobiographical memory in epilepsy.

Allebone, James; Rayner, Genevieve; Siveges, Benjamin; Wilson, Sarah J

2015-12-01

Research suggests that individuals with chronic epilepsy display differences in their self-identity. The mechanisms by which self-identity is altered, however, are not well understood. Neural networks supporting autobiographical memory retrieval in the mesial temporal (MT) lobe are thought to be fundamental to self-identity processes. Thus, we examined differences in self-identity and autobiographical memory in patients with either MT or non-mesial temporal (NMT) foci with early or late age of habitual seizure onset. Participants included 102 adults: 51 healthy individuals and 51 patients with drug-resistant focal seizures (19 MT, 32 NMT). We used the Ego Identity Process Questionnaire to profile the identity development of participants, and examined how this related to memory function assessed using the Autobiographical Memory Test. Patients and controls had strikingly different self-identity profiles, with early onset MT patients showing the least identity development compared to controls and other patient groups. In contrast, late-onset NMT patients showed the highest level of identity development of the patient groups and closely resembled healthy controls (p < 0.05 for all comparisons). For all MT patients, poor autobiographical memory retrieval was correlated with altered self-identity (p < 0.001). No associations between autobiographical memory and self-identity were evident in the NMT group. Self-identity in epilepsy may be modulated by the extent to which seizure foci impinge on the autobiographical memory network and the timing of seizure onset. Early disruption to MT regions of the autobiographical memory network may constitute a neurocognitive mechanism by which self-identity is altered in chronic focal epilepsy.

Spinal Health: The Backbone of Chiropractic's Identity.

PubMed

Brown, Richard A

2016-12-01

The purpose of this commentary is to explore the concepts underpinning professional identity, assess their relevance to chiropractic, and propose a model by which a strong identity for the chiropractic profession may be achieved. The professional identity of chiropractic has been a constant source of controversy throughout its history. Attempts to establish a professional identity have been met with resistance from internal factions divided over linguistics, philosophy, technique, and chiropractic's place in the health care framework. Consequently, the establishment of a clear identity has been challenging, and the chiropractic profession has failed to capitalize on its potential as the profession of spine care experts. Recent identity consultations have produced similar statements that position chiropractors as spinal health and well-being experts. Adoption of this identity, however, has not been universal, perpetuating the uncertainty with which the public regards the chiropractic profession. To gain public and professional acceptance, chiropractic must be unequivocal in declaring its scope, expertise, and intent. Failure to do so will lead to obscurity as other professions acquire necessary skills and position themselves as the custodians of spine care.

Physicians' duties and the non-identity problem.

PubMed

Hope, Tony; McMillan, John

2012-01-01

The non-identity problem arises when an intervention or behavior changes the identity of those affected. Delaying pregnancy is an example of such a behavior. The problem is whether and in what ways such changes in identity affect moral considerations. While a great deal has been written about the non-identity problem, relatively little has been written about the implications for physicians and how they should understand their duties. We argue that the non-identity problem can make a crucial moral difference in some circumstances, and that it has some interesting implications for when it is or is not right for a physician to refuse to accede to a patient's request. If a physician is asked to provide an intervention (identity preserving) that makes a person worse off, then such harm provides a good reason for the physician to refuse to provide the intervention. However, in cases where different (identity-altering) interventions result in different people having a better or worse life, physicians should normally respect patient choice.

Ego identity of adolescent children of alcoholics.

2007-01-01

The study examines the issue of ego identity among adolescent sons of alcoholic fathers. Forty-four adolescent sons of alcoholic fathers, age of 15-18, constituted the sample. They were drawn from public alcohol treatment center in Israel. The control group included 60 adolescents none of their parents is known as an alcoholic, sampled from integrative schools in the same neighborhood and matched by age. Ego identity was measured by Tzuriel's "Adolescent Ego Identity Scale" (AEIS). It was hypothesized that adolescent children of alcoholics will show lower scores of ego identity and of its dimensions. The hypothesis was not confirmed. To the contrary, adolescent children of alcoholics reported higher scores of "ego identity-total" and of four of the seven ego identity dimensions. One possible explanation is that children of alcoholics are maturing early in age compared to their controls. They have developed different coping strategies that facilitate creating a more "stable" ego identity compared to their peers. Another explanation is that children of alcoholics apply defense mechanisms that enhance the development of an "adaptive self."

Characterization of acid-tolerant H/CO-utilizing methanogenic enrichment cultures from an acidic peat bog in New York State.

Two methanogenic cultures were enriched from acidic peat soil using a growth medium buffered to c. pH 5. One culture, 6A, was obtained from peat after incubation with H(2)/CO(2), whereas culture NTA was derived from a 10(-4) dilution of untreated peat into a modified medium. 16S rRNA gene clone libraries from each culture contained one methanogen and two bacterial sequences. The methanogen 16S rRNA gene sequences were 99% identical with each other and belonged to the novel "R-10/Fen cluster" family of the Methanomicrobiales, whereas their mcrA sequences were 96% identical. One bacterial 16S rRNA gene sequence from culture 6A belonged to the Bacteroidetes and showed 99% identity with sequences from methanogenic enrichments from German and Russian bogs. The other sequence belonged to the Firmicutes and was identical to a thick rod-shaped citrate-utilizing organism isolated from culture 6A, the numbers of which decreased when the Ti (III) chelator was switched from citrate to nitrilotriacetate. Bacterial clones from the NTA culture clustered in the Delta- and Betaproteobacteria. Both cultures contained thin rods, presumably the methanogens, as the predominant morphotype, and represent a significant advance in characterization of the novel acidiphilic R-10 family methanogens.

Affiliative and "self-as-doer" identities: Relationships between social identity, social support, and emotional status amongst survivors of acquired brain injury (ABI).

2015-01-01

Social support is an important factor in rehabilitation following acquired brain injury (ABI). Research indicates that social identity makes social support possible and that social identity is made possible by social support. In order to further investigate the reciprocity between social identity and social support, the present research applied the concepts of affiliative and "self-as-doer" identities to an analysis of relationships between social identity, social support, and emotional status amongst a cohort of 53 adult survivors of ABI engaged in post-acute community neurorehabilitation. Path analysis was used to test a hypothesised mediated model whereby affiliative identities have a significant indirect relationship with emotional status via social support and self-as-doer identification. Results support the hypothesised model. Evidence supports an "upward spiral" between social identity and social support such that affiliative identity makes social support possible and social support drives self-as-doer identity. Our discussion emphasises the importance of identity characteristics to social support, and to emotional status, for those living with ABI.

Why be moral? Moral identity motivation and age.

Moral identity research to date has largely failed to provide evidence for developmental trends in moral identity, presumably because of restrictions in the age range of studies and the use of moral identity measures that are insensitive to age-related change. The present study investigated moral identity motivation across a broad age range (14-65 years, M = 33.48; N = 252) using a modified version of the Good Self-Assessment Interview. Individuals' moral identity motivation was coded and categorized as external, internal, or relationship-oriented. It was found that with age, external moral identity motivation decreased, whereas internal moral identity motivation increased. Effects of age were stronger in adolescence and emerging adulthood than in young adulthood and middle age. Findings underscore the developmental nature of the moral identity construct and suggest that moral motivation becomes more self-integrated with age.

Purpose: Comparison of the relative values of the ankle-arm index (AAI) at rest and after exercise, angiography, and duplex ultrasonography for the follow-up of percutaneous transluminal angioplasty (PTA) in patients with peripheral vascular disease. Methods: Thirty-two patients were prospectively followed after technically and clinically successful PTA of a femoropopliteal occlusion. The patency of the femoropopliteal artery was assessed for 1 year using AAI measurements at rest and after exercise; duplex ultrasonography at 4, 12, 24, 36, and 52 weeks; and angiography at 3 and 12 months after PTA. Results: Patency was highly dependent on the measurement technique. The cumulative patencymore » after 1 year determined with the AAI at rest and during exercise, by angiography, and by duplex ultrasonography was 74%, 19%, 31%, and 32%, respectively. Seventy-five percent of the restenoses occurred at the site of the treated occlusion. Conclusion: Duplex ultrasonography is most suitable for this assessment, as it causes no patient discomfort and the specificity is better than AAI after exercise because vascular disease in other, proximal segments does not interfere with the results.« less

Concurrent development of facial identity and expression discrimination.

Facial identity and facial expression processing both appear to follow a protracted developmental trajectory, yet these trajectories have been studied independently and have not been directly compared. Here we investigated whether these processes develop at the same or different rates using matched identity and expression discrimination tasks. The Identity task begins with a target face that is a morph between two identities (Identity A/Identity B). After a brief delay, the target face is replaced by two choice faces: 100% Identity A and 100% Identity B. Children 5-12-years-old were asked to pick the choice face that is most similar to the target identity. The Expression task is matched in format and difficulty to the Identity task, except the targets are morphs between two expressions (Angry/Happy, or Disgust/Surprise). The same children were asked to pick the choice face with the expression that is most similar to the target expression. There were significant effects of age, with performance improving (becoming more accurate and faster) on both tasks with increasing age. Accuracy and reaction times were not significantly different across tasks and there was no significant Age x Task interaction. Thus, facial identity and facial expression discrimination appear to develop at a similar rate, with comparable improvement on both tasks from age five to twelve. Because our tasks are so closely matched in format and difficulty, they may prove useful for testing face identity and face expression processing in special populations, such as autism or prosopagnosia, where one of these abilities might be impaired.

Testing a Model of Minority Identity Achievement, Identity Affirmation and Psychological Well-Being among Ethnic Minority and Sexual Minority Individuals

PubMed Central

2011-01-01

How is social identity related to psychological well-being among minority individuals? Drawing on developmental models of identity formation (e.g., Erikson, 1968) and on Social Identity Theory (Tajfel & Turner, 1979), we tested a conceptual model examining links between two key aspects of social identity and psychological well-being. We proposed that the association between identity achievement (exploring and understanding the meaning of one’s identity) and psychological well-being is mediated by identity affirmation (developing positive feelings and a sense of belonging to one’s social group). Across three studies, including ethnic minority high school students (Study 1), ethnic minority college students (Study 2) and lesbian and gay male adults (Study 3), we found strong support for the model. Results suggest that the process of exploring and understanding one’s minority identity can serve as an important basis for developing positive feelings toward and an enhanced sense of attachment to the group which can in turn confer psychological benefits for minority individuals. Implications and directions for future research are discussed. PMID:21341900

Claiming and displaying national identity: Irish travellers' and students' strategic use of 'banal' and 'hot' national identity in talk.

PubMed

Joyce, Carmel; Stevenson, Clifford; Muldoon, Orla

2013-09-01

Two complementary explanations have been offered by social psychologists to account for the universal hold of national identity, first that national identity is ideologically assumed, as it forms the 'banal' background of everyday life, and second that national identity is 'hotly' constructed and contested in political and everyday settings to great effect. However, 'banal' and 'hot' aspects of national identity have been found to be distributed unevenly across national and subnational groups and banality itself can be strategically used to distinguish between different groups. The present paper develops these ideas by examining possible reasons for these different modes and strategies of identity expression. Drawing upon intergroup theories of minority and majority relations, we examine how a group who see themselves unequivocally as a minority, Irish Travellers, talk about their national identity in comparison to an age and gender-matched sample of Irish students. We find that Travellers proactively display and claim 'hot' national identity in order to establish their Irishness. Irish students 'do banality', police the boundaries and reputation of Irishness, and actively reject and disparage proactive displays of Irishness. The implications for discursive understandings of identity, the study of intra-national group relations and policies of minority inclusion are discussed. © 2012 The British Psychological Society.

Identity, storytelling and the philanthropic journey.

This article develops theoretical understanding of the involvement of wealthy entrepreneurs in socially transformative projects by offering a foundational theory of philanthropic identity narratives. We show that these narratives are structured according to the metaphorical framework of the journey , through which actors envision and make sense of personal transformation. The journey provides a valuable metaphor for conceptualizing narrative identities in entrepreneurial careers as individuals navigate different social landscapes, illuminating identities as unfolding through a process of wayfinding in response to events, transitions and turning-points. We delineate the journey from entrepreneurship to philanthropy, and propose a typology of rewards that entrepreneurs claim to derive from giving. We add to the expanding literature on narrative identities by suggesting that philanthropic identity narratives empower wealthy entrepreneurs to generate a legacy of the self that is both self- and socially oriented, these 'generativity scripts' propelling their capacity for action while ensuring the continuation of their journeys.

Adolescent identity development and distress in a clinical sample.

PubMed

Wiley, Rachel E; Berman, Steven L

2013-12-01

The purpose of this study was to examine the relationships of identity development and identity distress to psychological adjustment within adolescents affected by psychological problems. Participants included 88 adolescents (43.2% female) ranging from 11 to 20 years of age who were receiving services from a community mental health center. A high proportion of the participants (22.7%) met the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition Text Revision criteria for Identity Problem. Regression analyses found psychopathology symptom score was associated with identity distress, identity exploration, and identity commitment, while identity distress was only related to psychopathology symptom score and not the other two identity variables. Adolescents with a clinical diagnosis may report significant levels of identity distress. Given that the relationship between psychopathology and identity distress may be reciprocal, assessing for identity issues might be prudent when conducting clinical diagnostic interviews and useful in treatment planning. © 2013 Wiley Periodicals, Inc.

Arabidopsis thaliana GH3.5 acyl acid amido synthetase mediates metabolic crosstalk in auxin and salicylic acid homeostasis

2016-01-01

In Arabidopsis thaliana, the acyl acid amido synthetase Gretchen Hagen 3.5 (AtGH3.5) conjugates both indole-3-acetic acid (IAA) and salicylic acid (SA) to modulate auxin and pathogen response pathways. To understand the molecular basis for the activity of AtGH3.5, we determined the X-ray crystal structure of the enzyme in complex with IAA and AMP. Biochemical analysis demonstrates that the substrate preference of AtGH3.5 is wider than originally described and includes the natural auxin phenylacetic acid (PAA) and the potential SA precursor benzoic acid (BA). Residues that determine IAA versus BA substrate preference were identified. The dual functionality of AtGH3.5 is unique to this enzyme although multiple IAA-conjugating GH3 proteins share nearly identical acyl acid binding sites. In planta analysis of IAA, PAA, SA, and BA and their respective aspartyl conjugates were determined in wild-type and overexpressing lines of A. thaliana. This study suggests that AtGH3.5 conjugates auxins (i.e., IAA and PAA) and benzoates (i.e., SA and BA) to mediate crosstalk between different metabolic pathways, broadening the potential roles for GH3 acyl acid amido synthetases in plants.

Identity, gender, and subjective well-being.

2011-01-01

Using the self-reported level of happiness as a measure of subjective well-being, this study examines the relationship between gender identity and subjective well-being with data from Taiwan. The findings suggest that an individual's perceptions about the ideals of women's gender roles in the labor market, the family, and politics are strongly related to his or her assigned social category, the prescriptions and characteristics associated with the social category, and the actions taken to match the ideals of gender identity. Consistent with Akerlof and Kranton's (2000) identity model, it is also found that an individual's gains or losses in gender identity lead to increases or decreases in the level of happiness.

Sport-Related Identities and the “Toxic Jock”

PubMed Central

Miller, Kathleen E.

2010-01-01

Little attention has been paid to the multidimensional nature of athletic involvement, which includes identity formation as well as participation in sports activities. Five hundred eighty-one sport-involved undergraduate students completed a questionnaire assessing their sport-related identities, goal orientations, primary sport ratings, and conformity to masculine norms. F-tested mean comparisons and hierarchical linear regressions were used to explore the characteristics associated with two distinct sport-related identities (“athletes” and “jocks”). Jock identity was associated with an ego-oriented approach to sports (men only), whereas athlete identity was associated with a task-oriented approach (both genders). Jock identity was positively associated with conformity to masculine norms, particularly for men, whereas athlete identity was positively associated with some masculine norms (i.e., Winning) and negatively associated with others (i.e., Playboy). These findings help to identify the correlates of a “toxic Jock” identity that may signal elevated risk for health-compromising behavior. PMID:21643553

Red herring in acid rain research

Havas, M.; Hutchinson, T.C.; Likens, G.E.

1984-06-01

Five common misconceptions, red herrings, regarding the effects of acid deposition on aquatic ecosystems are described in an attempt to clarify some of the confusion they have created. These misconceptions are the following: Bog lakes have been acidic for thousands of years; thus the acidification of lakes is not a recent phenomenon. The early methods for measuring pH are in error; therfore, no statements can be made regarding historical trends. Acidification of lakes and streams results from changed land use practices (forestry, agriculture, animal husbandry) and not acid deposition. The decrease in fish populations is caused by overfishing, disease, andmore » water pollution, not acidification. Because lakes that receive identical rainfall can have considerable different pHs, regional lake acidification cannot be due to acid precipitation. It is easy to suggest a whole series of alternative, and often unlikely, explanations of the causes and consequences of acid deposition. These keep scientists busy for years assembling and examining data only to conclude that the explanation is not valid. These tactics cause, and perhaps are designed to cause, continuous delay in remedial action. They fail to take into account the large body of information that deals with the sources of the acid deposition and the seriousness of its effects.« less

A dominant conformational role for amino acid diversity in minimalist protein–protein interfaces

DOE Office of Scientific and Technical Information (OSTI.GOV)

Gilbreth, Ryan N.; Esaki, Kaori; Koide, Akiko

Recent studies have shown that highly simplified interaction surfaces consisting of combinations of just two amino acids, Tyr and Ser, exhibit high affinity and specificity. The high functional levels of such minimalist interfaces might thus indicate small contributions of greater amino acid diversity seen in natural interfaces. Toward addressing this issue, we have produced a pair of binding proteins built on the fibronectin type III scaffold, termed “monobodies.” One monobody contains the Tyr/Ser binary-code interface (termed YS) and the other contains an expanded amino acid diversity interface (YSX), but both bind to an identical target, maltose-binding protein. The YSX monobodymore » bound with higher affinity, a slower off rate and a more favorable enthalpic contribution than the YS monobody. High-resolution X-ray crystal structures revealed that both proteins bound to an essentially identical epitope, providing a unique opportunity to directly investigate the role of amino acid diversity in a protein interaction interface. Surprisingly, Tyr still dominates the YSX paratope and the additional amino acid types are primarily used to conformationally optimize contacts made by tyrosines. Scanning mutagenesis showed that while all contacting Tyr side chains are essential in the YS monobody, the YSX interface was more tolerant to mutations. These results suggest that the conformational, not chemical, diversity of additional types of amino acids provided higher functionality and evolutionary robustness, supporting the dominant role of Tyr and the importance of conformational diversity in forming protein interaction interfaces.« less

Social Identities as Pathways into and out of Addiction.

PubMed

Dingle, Genevieve A; Cruwys, Tegan; Frings, Daniel

2015-01-01

There exists a predominant identity loss and "redemption" narrative in the addiction literature describing how individuals move from a "substance user" identity to a "recovery" identity. However, other identity related pathways influencing onset, treatment seeking and recovery may exist, and the process through which social identities unrelated to substance use change over time is not well understood. This study was designed to provide a richer understanding of such social identities processes. Semi-structured interviews were conducted with 21 adults residing in a drug and alcohol therapeutic community (TC) and thematic analysis revealed two distinct identity-related pathways leading into and out of addiction. Some individuals experienced a loss of valued identities during addiction onset that were later renewed during recovery (consistent with the existing redemption narrative). However, a distinct identity gain pathway emerged for socially isolated individuals, who described the onset of their addiction in terms of a new valued social identity. Almost all participants described their TC experience in terms of belonging to a recovery community. Participants on the identity loss pathway aimed to renew their pre-addiction identities after treatment while those on the identity gain pathway aimed to build aspirational new identities involving study, work, or family roles. These findings help to explain how social factors are implicated in the course of addiction, and may act as either motivations for or barriers to recovery. The qualitative analysis yielded a testable model for future research in other samples and settings.

To assess pharmacokinetic and pharmacodynamic interactions between naproxen (a non-steroidal anti-inflammatory drug) and apixaban (an oral, selective, direct factor-Xa inhibitor). In this randomized, three period, two sequence study, 21 healthy subjects received a single oral dose of apixaban 10 mg, naproxen 500 mg or co-administration of both. Blood samples were collected for determination of apixaban and naproxen pharmacokinetics and pharmacodynamics (anti-Xa activity, international normalized ratio [INR] and arachidonic acid-induced platelet aggregation [AAI-PA]). Adverse events, bleeding time and routine safety assessments were also evaluated. Apixaban had no effect on naproxen pharmacokinetics. However, following co-administration, apixaban AUC(0,∞), AUC(0,t) and Cmax were 54% (geometric mean ratio 1.537; 90% confidence interval (CI) 1.394, 1.694), 55% (1.549; 90% CI 1.400, 1.713) and 61% (1.611; 90% CI 1.417, 1.831) higher, respectively. Mean (standard deviation [SD]) anti-Xa activity at 3 h post-dose was approximately 60% higher following co-administration compared with apixaban alone, 4.4 [1.0] vs. 2.7 [0.7] IU ml(-1) , consistent with the apixaban concentration increase following co-administration. INR was within the normal reference range after all treatments. AAI-PA was reduced by approximately 80% with naproxen. Co-administration had no impact beyond that of naproxen. Mean [SD] bleeding time was higher following co-administration (9.1 [4.1] min) compared with either agent alone (5.8 [2.3] and 6.9 [2.6] min for apixaban and naproxen, respectively). Co-administration of naproxen with apixaban results in higher apixaban exposure and appears to occur through increased apixaban bioavailability. The effects on anti-Xa activity, INR and inhibition of AAI-PA observed in this study were consistent with the individual pharmacologic effects of apixaban and naproxen. © 2014 The British Pharmacological Society.

The Multicultural Identity Integration Scale (MULTIIS): Developing a comprehensive measure for configuring one's multiple cultural identities within the self.

PubMed

Yampolsky, Maya A; Amiot, Catherine E; de la Sablonnière, Roxane

2016-04-01

The research investigating how one's multiple cultural identities are configured within the self has yet to account for existing cultural identity configurations aside from integration, and for identifying with more than 2 cultural groups at once. The current research addresses these issues by constructing the Multicultural Identity Integration Scale (MULTIIS) to examine 3 different multicultural identity configurations, and their relationship to well-being based on Amiot and colleagues' (2007) cognitive-developmental model of social identity integration (CDSMII). Diverse samples of multicultural individuals completed the MULTIIS along with identity and well-being measures. (Study 1A: N = 407; 1B: N = 310; 2A = 338 and 2A = 254) RESULTS: Reliability and confirmatory factorial analyses (Studies 1A and 2A) all supported the factorial structure of the MULTIIS. Regression analyses (Studies 1B and 2B) confirmed that the integration subscale of the MULTIIS positively predicted well-being, whereas compartmentalization negatively predicted well-being. Categorization was inconsistently related to well-being. These findings support the CDSMII and the usefulness of the MULTIIS measure, and suggest that each identity configuration is uniquely related to well-being outcomes.

An integrated developmental model for studying identity content in context.

PubMed

Galliher, Renee V; McLean, Kate C; Syed, Moin

2017-11-01

Historically, identity researchers have placed greater emphasis on processes of identity development (how people develop their identities) and less on the content of identity (what the identity is). The relative neglect of identity content may reflect the lack of a comprehensive framework to guide research. In this article, we provide such a comprehensive framework for the study of the content of identity, including 4 levels of analysis. At the broadest level, we situate individual identity within historical, cultural, and political contexts, elaborating on identity development within the context of shifting cultural norms, values, and attitudes. Histories of prejudice and discrimination are relevant in shaping intersections among historically marginalized identities. Second, we examine social roles as unique and central contexts for identity development, such that relationship labels become integrated into a larger identity constellation. Third, domains of individual or personal identity content intersect to yield a sense of self in which various aspects are subjectively experienced as an integrated whole. We explore the negotiation of culturally marginalized and dominant identity labels, as well as idiosyncratic aspects of identities based on unique characteristics or group memberships. Finally, we argue that the content of identity is enacted at the level of everyday interactions, the "micro-level" of identity. The concepts of identity conflict, coherence, and compartmentalization are presented as strategies used to navigate identity content across these 4 levels. This framework serves as an organizing tool for the current literature, as well as for designing future studies on the identity development.

Bioinformatic Analysis Reveals Archaeal tRNATyr and tRNATrp Identities in Bacteria

PubMed Central

Mukai, Takahito; Reynolds, Noah M.; Crnković, Ana; Söll, Dieter

2017-01-01

The tRNA identity elements for some amino acids are distinct between the bacterial and archaeal domains. Searching in recent genomic and metagenomic sequence data, we found some candidate phyla radiation (CPR) bacteria with archaeal tRNA identity for Tyr-tRNA and Trp-tRNA synthesis. These bacteria possess genes for tyrosyl-tRNA synthetase (TyrRS) and tryptophanyl-tRNA synthetase (TrpRS) predicted to be derived from DPANN superphylum archaea, while the cognate tRNATyr and tRNATrp genes reveal bacterial or archaeal origins. We identified a trace of domain fusion and swapping in the archaeal-type TyrRS gene of a bacterial lineage, suggesting that CPR bacteria may have used this mechanism to create diverse proteins. Archaeal-type TrpRS of bacteria and a few TrpRS species of DPANN archaea represent a new phylogenetic clade (named TrpRS-A). The TrpRS-A open reading frames (ORFs) are always associated with another ORF (named ORF1) encoding an unknown protein without global sequence identity to any known protein. However, our protein structure prediction identified a putative HIGH-motif and KMSKS-motif as well as many α-helices that are characteristic of class I aminoacyl-tRNA synthetase (aaRS) homologs. These results provide another example of the diversity of molecular components that implement the genetic code and provide a clue to the early evolution of life and the genetic code. PMID:28230768

Group membership and social identity in addiction recovery.

PubMed

Buckingham, Sarah A; Frings, Daniel; Albery, Ian P

2013-12-01

Despite a growing interest in how group membership can positively impact health, little research has addressed directly the role social identity processes can have on recovery from addiction. Drawing on social identity theory and self-categorization theory, the present study investigated how recovery group membership can introduce a new social identity associated with recovery, compared to the social identity associated with addiction. We hypothesized that two processes--evaluative differentiation and identity preference--would be linked with higher self-efficacy and positive health outcomes (i.e., reduced relapse, lower levels of appetitive behavior, and elevated feelings of social connectedness [Study 2]). Study 1 recruited members (N = 61) from United Kingdom based mutual aid groups of Alcoholics Anonymous and Narcotics Anonymous. Study 2 recruited ex-smokers (N = 81) from online sources. In Study 1, evaluative differentiation was significantly related to lowered relapse and reduced appetitive behavior. Identity preference was related to higher levels of self-efficacy, which was related to months drug-free and reduced levels of appetitive behaviors. In Study 2, evaluative differentiation was related to identity preference. Identity preference was also related to higher self-efficacy, which in turn was related to lower relapse. Although exploratory, these results suggest that developing a social identity as a "recovering addict" or an "ex-smoker" and subsequently highlighting the difference between such identities may be a useful strategy for reducing relapse among people with problems associated with addictive behaviors.

Hoffer, L John

2016-05-01

Human protein and amino acid nutrition encompasses a wide, complex, frequently misunderstood, and often contentious area of clinical research and practice. This tutorial explains the basic biochemical and physiologic principles that underlie our current understanding of protein and amino acid nutrition. The following topics are discussed: (1) the identity, measurement, and essentiality of nutritional proteins; (2) the definition and determination of minimum requirements; (3) nutrition adaptation; (4) obligatory nitrogen excretion and the minimum protein requirement; (5) minimum versus optimum protein intakes; (6) metabolic responses to surfeit and deficient protein intakes; (7) body composition and protein requirements; (8) labile protein; (9) N balance; (10) the principles of protein and amino acid turnover, including an analysis of the controversial indicator amino acid oxidation technique; (11) general guidelines for evaluating protein turnover articles; (12) amino acid turnover versus clearance; (13) the protein content of hydrated amino acid solutions; (14) protein requirements in special situations, including protein-catabolic critical illness; (15) amino acid supplements and additives, including monosodium glutamate and glutamine; and (16) a perspective on the future of protein and amino acid nutrition research. In addition to providing practical information, this tutorial aims to demonstrate the importance of rigorous physiologic reasoning, stimulate intellectual curiosity, and encourage fresh ideas in this dynamic area of human nutrition. In general, references are provided only for topics that are not well covered in modern textbooks. © 2016 American Society for Parenteral and Enteral Nutrition.

Peroxygenase-Catalyzed Fatty Acid Epoxidation in Cereal Seeds (Sequential Oxidation of Linoleic Acid into 9(S),12(S),13(S)-Trihydroxy-10(E)-Octadecenoic Acid).

PubMed Central

Hamberg, M.; Hamberg, G.

1996-01-01

Peroxygenase-catalyzed epoxidation of oleic acid in preparations of cereal seeds was investigated. The 105,000g particle fraction of oat (Avena sativa) seed homogenate showed high peroxygenase activity, i.e. 3034 [plus or minus] 288 and 2441 [plus or minus] 168 nmol (10 min)-1 mg-1 protein in two cultivars, whereas the corresponding fraction obtained from barley (Hordeum vulgare and Hordeum distichum), rye (Secale cereale), and wheat (Triticum aestivum) showed only weak activity, i.e. 13 to 138 nmol (10 min)-1 mg-1 protein. In subcellular fractions of oat seed homogenate, peroxygenase specific activity was highest in the 105,000g particle fraction, whereas lipoxygenase activity was more evenly distributed and highest in the 105,000g supernatant fraction. Incubation of [1-14C]linoleic acid with the 105,000g supernatant of oat seed homogenate led to the formation of several metabolites, i.e. in order of decreasing abundance, 9(S)-hydroxy-10(E),12(Z)-octadecadienoic acid, 9(S),12(S),13(S)-trihydroxy-10(E)-octadecenoic acid, cis-9,10-epoxy-12(Z)-octadecenoic acid [mainly the 9(R),10(S) enantiomer], cis-12,13-epoxy-9(Z)-octadecenoic acid [mainly the 12(R),13(S) enantiomer], threo-12,13-dihydroxy-9(Z)-octadecenoic acid, and 12(R),13(S)-epoxy-9(S)-hydroxy-10(E)-octadecenoic acid. Incubation of linoleic acid with the 105,000g particle fraction gave a similar, but not identical, pattern of metabolites. Conversion of linoleic acid into 9(S),12(S),13(S)-trihydroxy-10(E)-octadecenoic acid, a naturally occurring oxylipin with antifungal properties, took place by a pathway involving sequential catalysis by lipoxygenase, peroxygenase, and epoxide hydrolase.

The experiment reported here is motivated by the idea that such judgments depend on reasoning about identity (e.g., the identity of the he who cleaned the house). Because the identity of an individual over time depends on the causal-historical path connecting the stages of the individual, the correct antecedent will also depend on causal connections. The experiment varied how likely it is that the event of the first sentence (e.g., the invitation) would cause the event of the second (the house cleaning) for each of the two individuals (the likelihood that if Albert invited Ron to dinner, this would cause Albert to clean the house, versus cause Ron to clean the house). Decisions about the antecedent followed causal likelihood. A mathematical model of causal identity accounted for most of the key aspects of the data from the individual sentence pairs.

[Identity and narration: autobiographical quests].

PubMed

Arfuch, Leonor

2013-01-01

This paper aims to tackle the subtle relation between autobiographical narratives and identity construction, from a non essentialist conception of identity. In a perspective that articulates philosophy of language, psychoanalysis, semiotics and literary critique, we posit the concept of biographical space as an analytical instrument to make a critical update of the reconfiguration of identities and subjectivities in contemporary culture, marked by the predominance of the biographical, the private and a kind of "public intimacy". This look is more symptomatic than descriptive: it intends to account for the rise of auto/biographical narratives and life-stories, from canonic genres to their multiple derivations in the media, social networks and the most diverse artistic practices, a phenomenon that seems to reaffirm the notion of narrative identities by Ricoeur. Our analysis here, from an ethic, aesthetic and political point of view, will focus on two visual arts experiences that have recently taken place for the first time in Buenos Aires: Christian Boltanski's and Tracey Emin's, solo exhibitions, each of them with a different biographical approach.

Social identity and cooperation in cultural evolution.

PubMed

Smaldino, Paul E

2017-12-06

I discuss the function of social identity signaling in facilitating cooperative group formation, and how the nature of that function changes with the structure of social organization. I propose that signals of social identity facilitate assortment for successful coordination in large-scale societies, and that the multidimensional, context-dependent nature of social identity is crucial for successful coordination when individuals have to cooperate in different contexts. Furthermore, the structure of social identity is tied to the structure of society, so that as societies grow larger and more interconnected, the landscape of social identities grows more heterogeneous. This discussion bears directly on the need to articulate the dynamics of emergent, ephemeral groups as a major factor in human cultural evolution. Copyright © 2017 The Author.

Drainage basin control of acid loadings to two Adirondack lakes

NASA Astrophysics Data System (ADS)

Booty, W. G.; Depinto, J. V.; Scheffe, R. D.

Two adjacent Adirondack Park (New York) calibrated watersheds (Woods Lake and Cranberry Pond), which receive identical atmospheric inputs, generate significantly different unit area of watershed loading rates of acidity to their respective lakes. A watershed acidification model is used to evaluate the watershed parameters which are responsible for the observed differences in acid loadings to the lakes. The greater overall mean depth of overburden on Woods Lake watershed, which supplies a greater buffer capacity as well as a longer retention time of groundwater, appears to be the major factor responsible for the differences.

Isomer-sensitive deboronation in reductive aminations of aryl boronic acids

DOE PAGES

Jones, Brad Howard; Wheeler, David R.; Wheeler, Jill S.; ...

2015-09-05

Deboronation is observed during the reductive amination of formylphenylboronic acid (FPBA) to the amine termini and side chains of peptides. This deboronation is sensitive to the isomerism of the boronic acid (BA), with ortho-FPBA yielding complete deboronation in the preparation of an N-terminally-modified dipeptide. The observed behavior is also clearly mediated by the chemical identity of the amine substrate. These results reveal a previously undocumented subtlety of BA functionalization and highlight the importance of thorough spectroscopic characterization in the preparation of peptide and small molecule BAs.

Self and identity over time: dementia.

PubMed

Brown, Juliette

2017-10-01

Here, the author revisits the discussion on the impact of dementia on experiences of self and identity over time that formed part of the workshop session on Mental Disorder and Selfhood at Kings College London, September 1, 2015. Dementia is described as being synonymous with loss, but this, in the author's view, is due to conscious and unconscious focus on the later stages of the illness that undermine all our abilities to think about and use the intervening years. Those years can deliver remarkable insights into the capacity to navigate fragmented identities. They can also remind us vividly of the importance of a relational, interactive quality to identity and the degree to which aspects of our selves and identities reside and thrive in the minds of others. © 2016 John Wiley & Sons, Ltd.

Gauthier, N.

2008-01-01

Two identities for the Bernoulli and for the Euler numbers are derived. These identities involve two special cases of central combinatorial numbers. The approach is based on a set of differential identities for the powers of the secant. Generalizations of the Mittag-Leffler series for the secant are introduced and used to obtain closed-form…

A Q-methodological study of smoking identities.

PubMed

Farrimond, Hannah; Joffe, Helene; Stenner, Paul

2010-10-01

In contrast to the psychological literature on adolescent smoking, little research has investigated the social identities of adult smokers. This study aimed to identify shared 'smoking identities' amongst a sample of 64 British smokers from different socio-economic groups using Q-methodology. Participants were asked to sort 70 items concerning smoking and smokers according to their agreement/disagreement with them. The 64 Q-sorts were then subjected to a by-person factor analysis yielding six factors, with the first four interpretable factors being presented here. Each factor is understood to represent a distinct 'identity position'. The first two, the 'addicted' smoker, and the 'in control' smoker, oriented around a biomedical model of smoking as an addictive health risk. The final two, the 'no big deal' smoker and the 'proud' smoker reflected alternative understandings and values. The identity positions also differed in the extent to which smoking was considered a core part of self-identity. Unpacking the 'smoking identities' of current smokers offers the opportunity to devise targeted health promotion.

Development of deaf identity: an ethnographic study.

PubMed

McIlroy, Guy; Storbeck, Claudine

2011-01-01

This ethnographic study explores the identity development of 9 deaf participants through the narratives of their educational experiences in either mainstream or special schools for the Deaf. This exploration goes beyond a binary conceptualization of deaf identity that allows for only the medical and social models and proposes a bicultural "dialogue model." This postmodern theoretical framework is used to examine the diversity of identities of deaf learners. The inclusion of the researcher's own fluid cross-cultural identity as a bicultural "DeaF" participant in this study provides an auto-ethnographic gateway into exploring the lives of other deaf, Deaf, or bicultural DeaF persons. The findings suggest that deaf identity is not a static concept but a complex ongoing quest for belonging, a quest that is bound up with the acceptance of being deaf while "finding one's voice" in a hearing-dominant society. Through the use of dialogue and narrative tools, the study challenges educators, parents, and researchers to broaden their understanding of how deaf identity, and the dignity associated with being a deaf person is constructed.
