    An α-amylase inhibitor producing Streptomyces sp. strain CC5 was isolated from soil. A proteinaceous α-amylase inhibitor AAI-CC5 was purified from strain CC5. AAI-CC5 specifically inhibited mammalian α-amylases. The molecular weight of the inhibitor was determined to be 8,212 Da by MALDI-TOF Mass Spectrum. The N-terminal 15 amino acid residues of the purified AAI-CC5 were DTGSPAPECVEYFQS, which is dissimilar to other reported proteinaceous α-amylase inhibitors. AAI-CC5 is a pH insensitive and heat-stable protein, and cannot be hydrolysed by trypsin. AAI-CC5 was cloned and expressed in Escherichia coli BL21 (DE3) with a hexa-histidine tag on the C terminal. AAI-CC5 shared 82 % identity with Parvulustat. The recombinant α-amylase inhibitor was purified to homogeneity by one-step affinity chromatography using Ni(2+)-NTA resin with molecular mass of 9,404 Da. Steady state kinetics studies of α-amylase and the inhibitor revealed an irreversible, non-competitive inhibition mechanism with IC50 and Ki value of 6.43 ×1 10(-11) and 4.45 × 10(-11) M respectively. These results suggest this novel α-amylase inhibitor possessed powerful inhibitory activity for α-amylase, and it may be a candidate in research of diabetes therapy and obesity treatment.

    Although Adverse Childhood Experiences (ACEs) are linked to increased health problems and risk behaviors in adulthood, there are no studies on the association between ACEs and adults' states of mind regarding their early childhood attachments, loss, and trauma experiences. To validate the ACEs questions, we analyzed the association between ACEs and emotional support indicators and Adult Attachment Interview (AAI) classifications in terms of unresolved mourning regarding past loss or trauma and discordant states of mind in cannot classify (U/CC) interviews. Seventy-five urban women (41 clinical and 34 community) completed a questionnaire on ACEs, which included 10 categories of abuse, neglect, and household dysfunction, in addition to emotional support. Internal psychological processes or states of mind concerning attachment were assessed using the AAI. ACE responses were internally consistent (Cronbach's α=.88). In the clinical sample, 84% reported≥4 ACEs compared to 27% among the community sample. AAIs judged U/CC occurred in 76% of the clinical sample compared to 9% in the community sample. When ACEs were≥4, 65% of AAIs were classified U/CC. Absence of emotional support in the ACEs questionnaire was associated with 72% of AAIs being classified U/CC. As the number of ACEs and the lack of emotional support increases so too does the probability of AAIs being classified as U/CC. Findings provide rationale for including ACEs questions in pediatric screening protocols to identify and offer treatment reducing the intergenerational transmission of risk associated with problematic parenting.

    The purpose of this study was to develop an evaluation method for animal-assisted intervention (AAI) programs involving Mood Check List-Short form.2 (MCL-S.2) and the State-Trait Anxiety Inventory (STAI) for psychiatric daycare of Japanese alcohol. dependents. A total of 36 alcohol dependents completed the study and questionnaires assessing their state. A single session of AAI reduced both subjective and physiological measures of state anxiety (A-State); and this program induced a significant reduction in the anxiety after an AAI program session with the dogs and cats involved in the intervention (p = 0.001). The Wilcoxon t-test showed that there were also significant differences in the "anxiety", "pleasantness", and "relaxation". scores for MCL-S.2 among the alcohol dependents, before and after AAI; a significantly decreased "anxiety" score (p = 0.006), and increased "pleasantness" (p = 0.002) and "relaxation" (p=0.012) scores for MCL-S.2 after AAI. The results of this study indicated that alcohol dependents who experienced a group AAI session-program exhibited significant improvements in their feeling; decreased anxiety, and increased pleasantness and relaxation.

    manage the use of the subsurface of the Earth. 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. This use case aims at exploiting the EGI FedCloud e-infrastructure for Data

    The main aim of this study was to investigate the correlates of a Hostile-Helpless (HH) state of mind among 67 women belonging to a community sample and two different at-risk samples matched on socio-economic indicators, including 20 women from low-SES population (poverty sample) and 15 women at risk for maltreatment being monitored by the social services for the protection of juveniles (maltreatment risk sample). The Adult Attachment Interview (AAI) protocols were reliably coded blind to the samples' group status. The rates of HH classification increased in relation to the risk status of the three samples, ranging from 9% for the low-risk sample to 60% for the maltreatment risk sample to 75% for mothers in the maltreatment risk sample who actually maltreated their infants. In terms of the traditional AAI classification system, 88% of the interviews from the maltreating mothers were classified Unresolved/Cannot Classify (38%) or Preoccupied (50%). Partial overlapping between the 2 AAI coding systems was found, and discussion concerns the relevant contributions of each AAI coding system to understanding of the intergenerational transmission of maltreatment.

  7. Noggin and retinoic acid transform the identity of avian facial prominences.

    PubMed

    Lee, S H; Fu, K K; Hui, J N; Richman, J M

    The signals that determine body part identity in vertebrate embryos are largely unknown, with some exceptions such as those for teeth and digits. The vertebrate face is derived from small buds of tissue, facial prominences, that surround the embryonic oral cavity. In chicken embryos, the skeleton of the upper beak is derived from the frontonasal mass and maxillary prominences. Here we show that bone morphogenetic proteins (Bmps) and the vitamin A derivative, retinoic acid (RA), are used to specify the identity of the frontonasal mass and maxillary prominences. Implanting two beads adjacent to the stage-15 presumptive maxillary field, one soaked in the Bmp antagonist Noggin and one soaked in RA, induces a duplicate set of frontonasal mass skeletal elements in place of maxillary bones. We also show that the duplicated beak is due to transformation of the maxillary prominence into a second frontonasal mass and not due to ectopic migration of cells or splitting of the normal frontonasal mass. Thus the levels of Bmp and RA determine whether specific regions of the face form maxillary or frontonasal mass derivatives.

    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.

    Aristolochic acids are natural nitro-compounds found globally in the plant genus Aristolochia that have been implicated in the severe illness in humans termed aristolochic acid nephropathy (AAN). Aristolochic acids undergo nitroreduction, among other metabolic reactions, and active intermediates arise that are carcinogenic. Previous experiments with rats showed that aristolochic acid I (AA-I), after oral administration or injection, is subjected to detoxication reactions to give aristolochic acid Ia, aristolactam Ia, aristolactam I and their glucuronide and sulfate conjugates that can be found in urine and faeces. Results obtained with whole rats do not clearly define the role of liver and kidney in such metabolic transformation. In this study, in order to determine the specific role of the kidney on the renal disposition of AA-I and to study the biotransformations suffered by AA-I in this organ, isolated kidneys of rats were perfused with AA-I. AA-I and metabolite concentrations were determined in perfusates and urines using HPLC procedures. The isolated perfused rat kidney model showed that AA-I distributes rapidly and extensively in kidney tissues by uptake from the peritubular capillaries and the tubules. It was also established that the kidney is able to metabolize AA-I into aristolochic acid Ia, aristolochic acid Ia O-sulfate, aristolactam Ia, aristolactam I and aristolactam Ia O-glucuronide. Rapid demethylation and sulfation of AA-I in the kidney generate aristolochic acid Ia and its sulfate conjugate that are voided to the urine. Reduction reactions to give the aristolactam metabolites occur to a slower rate. Renal clearances showed that filtered AA-I is reabsorbed at the tubules whereas the metabolites are secreted. The unconjugated metabolites produced in the renal tissues are transported to both urine and perfusate whereas the conjugated metabolites are almost exclusively secreted to the urine. PMID:22118289

    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.

    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 epithelial 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.

    Aristolochic acid (AA) is a natural bioactive substance found in Chinese herbs that induce toxicity during ovarian maturation of animals and humans. Apoptosis is induced by various types of damage and governs the progression of biological cell removal that controls the equilibrium between cell growth and death. However, the AA toxicity mechanism during testis maturation in mouse has not been elucidated and was thus the focus of the present study. This study used TM4 Sertoli cells and an ICR mouse model, both of which were injected with aristolochic acid I (AAI) for 4 weeks. Testis dimensions and weight were surveyed to define AAI cytotoxicity in the mice testis. The MTT assay was used to analyze the cytotoxicity of AAI in TM4 Sertoli cells. An apoptosis expression mediator was analyzed through Western blotting, while the measure of apoptosis-induced cell death of TM4 Sertoli cells and testis tissues was analyzed by the TUNEL assay. We found that AAI strongly inhibits survival in TM4 cells and that AAI significantly activated apoptosis-induced cell death in TM4 Sertoli cells and mice testis tissue. In addition, AAI suppressed the expression of B-cell lymphoma 2 (Bcl-2), a factor related to anti-apoptosis. It markedly improved pro-apoptotic protein expression, including Bcl-2-associated X protein, poly(ADP-ribose) polymerase, and caspase-3 and -9. Furthermore, we observed that AAI significantly reduced the size and weight of mouse testis. Moreover, germ cells and somatic cells in testis were markedly damaged by AAI. In addition, we found that AAI significantly inhibits ERK1/2 and Akt activation in TM4 Sertoli cells and testis tissue. The data obtained in this study indicate that AAI causes severe injury for the period of testis development by impeding apoptosis related to the Akt and ERK1/2 pathway.

    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(−/−) 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.

    Ex situ catalytic fast pyrolysis (CFP) is a promising route for producing fungible biofuels; however, this process requires bifunctional catalysts that favor C–O bond cleavage, activate hydrogen at near atmospheric pressure and high temperature (350–500 °C), and are stable under high-steam, low hydrogen-to-carbon environments. Recently, early transition-metal carbides have been reported to selectively cleave C–O bonds of alcohols, aldehydes, and oxygenated aromatics, yet there is limited understanding of the metal carbide surface chemistry under reaction conditions and the identity of the active sites for deoxygenation. In this study, we evaluated molybdenum carbide (Mo2C) for the deoxygenation of acetic acid, an abundant component of biomass pyrolysis vapors, under ex situ CFP conditions, and we probed the Mo2C surface chemistry, identity of the active sites, and deoxygenation pathways using in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), X-ray photoelectron spectroscopy (XPS), and density functional theory (DFT) calculations.

    The cDNA for rat androgen-binding protein (ABP) was previously isolated from a bacteriophage lambda gt11 rat testis cDNA library and its identity was confirmed by epitope selection. Hybrid-arrested translation studies have now demonstrated the identity of the isolates. The nucleotide sequence of a near full-length cDNA encodes a 403-amino acid precursor (Mr = 44,539), which agrees in size with the cell-free translation product (Mr = 45,000) of ABP mRNA. Putative sites of N-glycosylation and signal peptide cleavage were identified. Comparison of the predicted amino acid sequence of rat ABP with the amino-terminal amino acid sequence of human sex hormone-binding globulin revealed that 17 of 25 residues are identical. On the basis of the predicted amino acid sequence the molecular weight of the primary translation product, lacking the signal peptide, was 41,183. Hybridization analyses indicated that the two subunits of ABP are coded for by a single gene and a single mRNA species. Our results suggest that ABP consists of two subunits with identical primary sequences and that differences in post-translational processing result in the production of 47,000 and 41,000 molecular weight monomers.

    The reduction of Salmonella prevalence in broilers is a priority in European Union agricultural policies because treatment with antibiotics is forbidden by Regulation (EC) 2160/2003. Two trials were conducted to evaluate the efficacy of a microencapsulated blend of sorbic acid and nature-identical compounds (i.e., chemically synthesized botanicals; SAB) on the reduction of the cecal prevalence and contents of Salmonella enterica serovars Hadar and Enteritidis in experimentally infected chickens. In the first trial, 125 one-day-old Lohmann specific-pathogen-free chickens were assigned to one of the following treatments: negative control (not challenged and not treated), positive control (challenged and not treated), SAB0.3, SAB1, or SAB5 (challenged and treated with the microencapsulated blend included in the feed at 0.03, 0.1, or 0.5%, respectively). At 30 d of age, birds were infected with 10(6) cfu of Salmonella Hadar, and after 5, 10, or 20 d postinfection, 5, 10, and 10 birds per treatment, respectively, were killed and the cecal contents and liver and spleen samples were analyzed for Salmonella Hadar. In the second trial, 100 one-day-old Ross 708 chickens were assigned to 1 of 5 treatments: control (not treated), SAB0.3, SAB1, SAB2, or SAB5 (treated with the blend included in the feed at 0.03, 0.1, 0.2, or 0.5%, respectively). At 7 d of age, the birds were challenged with 10(5) cfu of Salmonella Enteritidis, and after 7, 14, or 24 d after challenge, 5, 5, and 10 birds per treatment, respectively, were killed and cecal contents were analyzed for Salmonella Enteritidis. Results showed that in the early stage of infection Salmonella prevalence was high in both studies, whereas at the end of the observation periods, the blends at 0.03, 0.1, and 0.5 in the challenge with Salmonella Hadar and at 0.2 and 0.5% in the challenge with Salmonella Enteritidis significantly reduced (by 2 log(10) cfu) the cecal content of Salmonella.

    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 and 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.

    The effects of acetic acid pretreatment on the texture of cooked potato slices were investigated in this work. Potato slices were pretreated with acetic acid immersion (AAI), distilled water immersion (DWI), or no immersion (NI). Subsequently, the cell wall material of the pretreated samples was isolated and fractioned to evaluate changes in the monosaccharide content and molar mass (MM), and the hardness and microscopic structure of the potato slices in different pretreatments before and after cooking were determined. The results showed that the highest firmness was obtained with more intact structure of the cell wall for cooked potato slices with AAI pretreatment. Furthermore, the MM and sugar ratio demonstrated that the AAI pretreated potato slices contained a higher content of the small molecular polysaccharides of cell walls, especially in the hemicellulose fraction. This work may provide a reference for potato processing.

    In all previous examples of complexes formed between protic acids and haloethylenes, we have observed similar modes of binding regardless of the specific identity of the acid, HF, HCl, or HCCH. Although details of the structures, such as hydrogen bond length and amount of deviation from linearity, do reflect the strength of the interaction and show clear correlations with the gas-phase acidity, the complexes of a given haloethylene with any of the acids have identical structural motifs. As part of a systematic study of the effects of chlorine substitution on intermolecular interactions of haloethylenes, we have studied the complexes of vinyl chloride with both HF and HCCH. The HF complex, reported last year, has a geometry with HF interacting across the double bond of vinyl chloride and forming a secondary interaction with the hydrogen cis to the chlorine atom. We have obtained the broadband, chirped-pulse and narrow band, Balle-Flygare Fourier transform microwave spectra of the vinyl chloride-HCCH complex. The spectra indicate that HCCH locates at one end of the vinyl chloride with the secondary interaction occurring with the geminal hydrogen atom.

    Aristolochic acid I (AAI) is a plant drug found in Aristolochia species that causes aristolochic acid nephropathy, Balkan endemic nephropathy and their associated urothelial malignancies. AAI is activated via nitroreduction producing genotoxic N-hydroxyaristolactam, which forms DNA adducts. The major enzymes responsible for the reductive bioactivation of AAI are NAD(P)H:quinone oxidoreductase and cytochromes P450 (CYP) 1A1 and 1A2. Using site-directed mutagenesis we investigated the possible mechanisms of CYP1A1/1A2/1B1-catalyzed AAI nitroreduction. Molecular modelling predicted that the hydroxyl groups of serine122/threonine124 (Ser122/Thr124) amino acids in the CYP1A1/1A2-AAI binary complexes located near to the nitro group of AAI, are mechanistically important as they provide the proton required for the stepwise reduction reaction. In contrast, the closely related CYP1B1 with no hydroxyl group containing residues in its active site is ineffective in catalyzing AAI nitroreduction. In order to construct an experimental model, mutant forms of CYP1A1 and 1A2 were prepared, where Ser122 and Thr124 were replaced by Ala (CYP1A1-S122A) and Val (CYP1A2-T124V), respectively. Similarly, a CYP1B1 mutant was prepared in which Ala133 was replaced by Ser (CYP1B1-A133S). Site-directed mutagenesis was performed using a quickchange approach. Wild and mutated forms of these enzymes were heterologously expressed in Escherichia coli and isolated enzymes characterized using UV-vis spectroscopy to verify correct protein folding. Their catalytic activity was confirmed with CYP1A1, 1A2 and 1B1 marker substrates. Using 32P-postlabelling we determined the efficiency of wild-type and mutant forms of CYP1A1, 1A2, and 1B1 reconstituted with NADPH:CYP oxidoreductase to bioactivate AAI to reactive intermediates forming covalent DNA adducts. The S122A and T124V mutations in CYP1A1 and 1A2, respectively, abolished the efficiency of CYP1A1 and 1A2 enzymes to generate AAI-DNA adducts. In contrast

    Dioxin-like compounds (DLCs) are pollutants of global environmental concern. DLCs elicit their adverse outcomes through activation of the aryl hydrocarbon receptor (AhR). However, there is limited understanding of the mechanisms that result in differences in sensitivity to DLCs among different species of fishes. Understanding these mechanisms is critical for protection of the diversity of fishes exposed to DLCs, including endangered species. This study investigated specific mechanisms that drive responses of two endangered fishes, white sturgeon (Acipenser transmontanus) and lake sturgeon (Acipenser fulvescens) to DLCs. It determined whether differences in sensitivity to activation of AhRs (AhR1 and AhR2) can be predicted based on identities of key amino acids in the ligand binding domain (LBD). White sturgeon were 3- to 30-fold more sensitive than lake sturgeon to exposure to 5 different DLCs based on activation of AhR2. There were no differences in sensitivity between white sturgeon and lake sturgeon based on activation of AhR1. Adverse outcomes as a result of exposure to DLCs have been shown to be mediated through activation of AhR2, but not AhR1, in all fishes studied to date. This indicates that white sturgeon are likely to have greater sensitivity in vivo relative to lake sturgeon. Homology modeling and in silico mutagenesis suggests that differences in sensitivity to activation of AhR2 result from differences in key amino acids at position 388 in the LBD of AhR2 of white sturgeon (Ala-388) and lake sturgeon (Thr-388). This indicates that identities of key amino acids in the LBD of AhR2 could be predictive of both in vitro activation by DLCs and in vivo sensitivity to DLCs in these, and potentially other, fishes.

    Acid-sensing ion channels (ASICs) are activated by an increase in the extracellular proton concentration. There are four genes (ASIC1-4) that encode six subunits, and they are involved in diverse neuronal functions, such as mechanosensation, learning and memory, nociception, and modulation of retinal function. In this study, we characterize the ASIC currents of spiral ganglion neurons (SGNs). These ASIC currents are primarily carried by Na+, exhibit fast activation and desensitization, display a pH50 of 6.2 and are blocked by amiloride, indicating that these are ASIC currents. The ASIC currents were further characterized using several pharmacological tools. Gadolinium and acetylsalicylic acid reduced these currents, and FMRFamide, zinc (at high concentrations) and N,N,N’,N’–tetrakis-(2-piridilmetil)-ethylenediamine increased them, indicating that functional ASICs are composed of the subunits ASIC1, ASIC2, and ASIC3. Neomycin and streptomycin reduced the desensitization rate of the ASIC current in SGNs, indicating that ASICs may contribute to the ototoxic action of aminoglycosides. RT-PCR of the spiral ganglion revealed significant expression of all ASIC subunits. By immunohistochemistry the expression of the ASIC1a, ASIC2a, ASIC2b, and ASIC3 subunits was detected in SGNs. Although only a few SGNs exhibited action potential firing in response to an acidic stimulus, protons in the extracellular solution modulated SGN activity during sinusoidal stimulation. Our results show that protons modulate the excitability of SGNs via ASICs. PMID:26733809

    The evolution of new gene networks is a primary source of genetic innovation that allows bacteria to explore and exploit new niches, including pathogenic interactions with host organisms. For example, the archetypal DNA binding protein, OmpR, is identical between Salmonella Typhimurium serovar Typhimurium and Escherichia coli, but regulatory specialization has resulted in different environmental triggers of OmpR expression and largely divergent OmpR regulons. Specifically, ompR mRNA and OmpR protein levels are elevated by acid pH in S. Typhimurium but not in E. coli. This differential expression pattern is due to differences in the promoter regions of the ompR genes and the E. coli ompR orthologue can be made acid-inducible by introduction of the appropriate sequences from S. Typhimurium. The OmpR regulon in S. Typhimurium overlaps that of E. coli at only 15 genes and includes many horizontally acquired genes (including virulence genes) that E. coli does not have. We found that OmpR binds to its genomic targets in higher abundance when the DNA is relaxed, something that occurs in S. Typhimurium as a result of acid stress and which is a requirement for optimal expression of its virulence genes. The genomic targets of OmpR do not share a strong nucleotide sequence consensus: we propose that the ability of OmpR to recruit additional genes to its regulon arises from its modest requirements for specificity in its DNA targets with its preference for relaxed DNA allowing it to cooperate with DNA-topology-based allostery to modulate transcription in response to acid stress.

    The amino acid sequences of the alpha- and beta-chains from the major hemoglobin component (HbA) of Canada goose (Branta canadensis) and mute swan (Cygnus olor) are given. The alpha-chains are of the alpha A-type, since alpha D-type was expressed but only found in low concentrations. By homologous comparison, greylag goose hemoglobin (Anser anser) and Canada goose hemoglobin alpha-chains differ by two exchanges, and beta-chains by three exchanges. A valine substitution for threonine was found at position alpha 34 (B15). This exchange is a result of a two point mutation. Thus, there are three nucleotide mutations in alpha-chains, as in beta-chains. Substitutions in positions alpha 34 (B15) and beta 125 (H3) have modified intersubunit contacts (alpha 1 beta 1-contacts). A comparison of mute swan hemoglobin with greylag goose hemoglobin shows four exchanges in alpha-chains and three in beta-chains. Canada goose and mute swan have identical beta-chains, while alpha-chains differ in two amino acids. One of these exchanges is implicated in one of the alpha 1 beta 1-contact points (alpha 34) where isoleucine substitution for valine was found. Comparison of hemoglobins from different species in the same tribe (Anserini) shows a high homology between Canada goose and mute swan hemoglobins.

    Background Transgenic proteins expressed by genetically modified food crops are evaluated for their potential allergenic properties prior to marketing, among others by identification of short identical amino acid sequences that occur both in the transgenic protein and allergenic proteins. A strategy is proposed, in which the positive outcomes of the sequence comparison with a minimal length of six amino acids are further screened for the presence of potential linear IgE-epitopes. This double track approach involves the use of literature data on IgE-epitopes and an antigenicity prediction algorithm. Results Thirty-three transgenic proteins have been screened for identities of at least six contiguous amino acids shared with allergenic proteins. Twenty-two transgenic proteins showed positive results of six- or seven-contiguous amino acids length. Only a limited number of identical stretches shared by transgenic proteins (papaya ringspot virus coat protein, acetolactate synthase GH50, and glyphosate oxidoreductase) and allergenic proteins could be identified as (part of) potential linear epitopes. Conclusion Many transgenic proteins have identical stretches of six or seven amino acids in common with allergenic proteins. Most identical stretches are likely to be false positives. As shown in this study, identical stretches can be further screened for relevance by comparison with linear IgE-binding epitopes described in literature. In the absence of literature data on epitopes, antigenicity prediction by computer aids to select potential antibody binding sites that will need verification of IgE binding by sera binding tests. Finally, the positive outcomes of this approach warrant further clinical testing for potential allergenicity. PMID:12477382

    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 <0.78ngmL(-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 0.29ngmL(-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 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 acids (AAs) are plant-derived nephrotoxins and carcinogens responsible for chronic renal failure and associated urothelial cell cancers in several clinical syndromes known collectively as aristolochic acid nephropathy (AAN). Mice provide a useful model for study of AAN because the renal histopathology of AA-treated mice is strikingly similar to that of humans. AA is also a potent carcinogen in mice with a tissue spectrum somewhat different from that in humans. The toxic dose of AA in mice is higher than that in humans; this difference in susceptibility has been postulated to reflect differing rates of detoxication between the species. Recent studies in mice have shown that the hepatic cytochrome P450 system detoxicates AA, and inducers of the arylhydrocarbon response protect mice from the nephrotoxic effects of AA. The purpose of this study was to determine the role of specific cytochrome P450 (P450) enzymes in AA metabolism in vivo. Of 18 human P450 enzymes we surveyed only two, CYP1A1 and CYP1A2, which were effective in demethylating 8-methoxy-6-nitro-phenanthro-(3,4-d)-1,3-dioxolo-5-carboxylic acid (AAI) to the nontoxic derivative 8-hydroxy-6-nitro-phenanthro-(3,4-d)-1,3-dioxolo-5-carboxylic acid (AAIa). Kinetic analysis revealed similar efficiencies of formation of AAIa by human and rat CYP1A2. We also report here that CYP1A2-deficient mice display increased sensitivity to the nephrotoxic effects of AAI. Furthermore, Cyp1a2 knockout mice accumulate AAI-derived DNA adducts in the kidney at a higher rate than control mice. Differences in bioavailability or hepatic metabolism of AAI, expression of CYP1A2, or efficiency of a competing nitroreduction pathway in vivo may explain the apparent differences between human and rodent sensitivity to AAI.

    The molecularly imprinted polymers (MIP) were prepared via aqueous RAFT precipitation polymerization, with aristolochic acid I (AAI) as the template molecule, AA as the functional monomer, EGDMA as the cross-linker, AIBN as the chain initiator, CTP as the chain transfer agent and 80% (g/g) DMF-aqueous solution as the porogen. The differential UV-vis spectra revealed that a cooperative hydrogen-bonding complex between AAI and AA might be formed at the molar ratio of 1:3 in prepolymerized system. The synthesized MIPs were characterized by FTIR spectra, solid UV-visible absorption spectra, nitrogen adsorption-desorption isotherms and scanning electron microscope, which proved that the MIPs and NIPs have the similar chemical structures and the adding of AAI could affect the size and morphology of the microspheres. UV-visible absorption spectra and High-performance liquid chromatography (HPLC) was used to investigate the adsorption and recognition properties of the MIPs. The Scatchard isotherm model described that the binding sites independently acted. The Langmuir isotherm model suggested an excellent imprinting effect owing to the presence of a large number of specific binding sites on the MIP. The Freundlich model indicated that the AAI could be readily absorbed by MIP. Selective absorption of the template molecule was demonstrated in presence of its analogous compounds, benzoic acid and nitrobenzene. The recycling experiments implied that the MIP could be reused to further selective recognition and separation to AAI for six times at least. MIP was developed for removal of AAI from the Aristolochia manshuriensis extraction. The results indicated that 25mg of MIP could remove the AAI below the HPLC detection limits (6.47ngmL(-1)) from 5.0mL of the extraction (CAAI=0.0018mgmL(-1)) with the recovery of AAI to 91.50% (n=3, SD=4.24%). Therefore, it is clearly revealed that the MIP can be a useful tool to remove toxic compounds from natural products.

    Identity federations throughout the world including InCommon in the United States, SURFnet in the Netherlands, DFN-AAI in Germany, GakuNin in Japan, and the UK Access Management Federation for Education and Research have made federated identities available for a large number of astronomers, astrophysicists, and other researchers. The LIGO project has recently joined the InCommon federation and is beginning the process to both consume federated identities from outside of LIGO and to make the LIGO identities issued to collaboration members available for consumption by other research communities. Consuming federated identity, however, is only the beginning. Realizing the promise of multi-messenger astronomy requires efficient collaboration among individuals from multiple communities. Efficient collaboration begins with federated identity but also requires robust collaboration management platforms providing consistent, scalable identity and access control information to collaboration applications including wikis, calendars, mailing lists and science portals. LIGO, together with collaborators from Internet2, is building the COmanage suite of tools for Collaborative Organization Management. Using COmanage and leveraging federated identities we plan to streamline electronic collaboration between LIGO and other astronomy projects so that scientists spend less time managing accounts and access control and more time doing science.

    In all previous examples of complexes formed between protic acids and haloethylenes, we have observed similar modes of binding regardless of the specific identity of the acid, HF, HCl, or HCCH. Although details of the structures, such as hydrogen bond length and amount of deviation from linearity, do reflect the strength of the interaction and show clear correlations with the gas-phase acidity, the complexes of a given haloethylene with any of the acids have identical structural motifs. Vinyl chloride, on the other hand, has been observed to adopt different modes of binding in its interactions with HF and HCCH. The HF complex, reported two years ago, has a geometry with HF interacting across the double bond of vinyl chloride and forming a secondary interaction with the hydrogen cis to the chlorine atom, but in the complex with acetylene, reported last year, HCCH locates at one end of the vinyl chloride with the secondary interaction occurring with the geminal hydrogen atom. This variety continues and is expanded in the vinyl chloride-HCl complex. Ab initio theory predicts a complex that has the HCl molecule interacting across the double bond, but located out of the vinyl chloride plane. The microwave spectrum of the most abundant isotopologue of this complex is consistent with theoretical predictions and additionally shows the presence of large amplitude motion connecting two equivalent structures.

    About 83% of the amino acid sequence of hemocyanin subunit HR6 from the Southeast Asian horseshoe crab, Carcinoscorpius rotundicauda, has been determined. There is a difference of about 43% between HR6 and complete sequences of chelicerate hemocyanin subunits from the American horseshoe crab, Limulus polyphemus, and a tarantula, Eurypelma californicum. However, the immunologically identical subunits HR6 and HT6 from Tachypleus tridentatus (Japanese horseshoe crab) show 2.7% sequence difference. Based on the amino acid sequences of HR6 and HT6, the divergence between C. rotundicauda and T. tridentatus occurred about 9.6 million years ago. In the case of horseshoe crab hemocyanin subunits, it seems that the orthologous homologues in many homologous subunits between species are immunologically detectable.

    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, leading 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.

    A DNA fragment containing the aroA(G) gene of Bacillus subtilis 168, encoding 3-deoxy-D-arabino-heptulosonate 7-phosphate (DAHP) synthase-chorismate mutase, was cloned and sequenced. The N-terminus of the protein encoded by aroA(G) showed homology with chorismate mutase encoded by aroH of B. subtilis and with the chorismate mutase parts of proteins encoded by the pheA and tyrA genes of Escherichia coli. The C-terminus of the aroA(G) product has sequence similarity with 3-deoxy-D-manno-octulosonate 8-phosphate synthase of E. coli. It was shown that the proteins encoded by the aroA(G) gene of B. subtilis 168 and the aroA gene of B. subtilis ATCC 6051 Marburg strain are identical, so the observed differences in DAHP synthase activity from these two strains must result from other changes.

    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.

    For the last 20 years the concepts of identity and identification have been subject to much interest in the humanities and social sciences. However, the implications of genetics for identity and identification have been largely neglected. In this paper, I distinguish various conceptions of identity (as continuity over time, as basic kind of being, as unique set of properties, and as social role) and identification (as subjective experience of identity in various senses and as social ascription of identity in various senses), and investigate systematically genetic perspectives on each of these conceptions. I stress the importance of taking the genetic perspectives seriously but also their limitations. In particular, I pinpoint conceptual problems that arise when a genetic approach to identity is adopted.

    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.

    The purpose of this study was to assess the carcinogenic activity of aristolochic acid I (AAI) in short-term high doses. Forty-four female Sprague-Dawley rats were randomly assigned to two groups. A dose of 50 mg/kg/day AAI was administrated to rats in the experimental group by gavage consecutively for 3 days, while the control group received only distilled water, after which renal function and pathological changes were assessed. At day 8 post-treatment AAI had induced elevations of both plasma urea and creatinine, coupled with increased urine production, urinary proteins, glucose and N-acetyl-beta-glucosaminidase. At 1, 3 and 6 months post-treatment renal function and urinary parameters for the experimental group approached baseline values. However, tumours and preneoplastic proliferation were both observed at 6 months for the experimental group. The rate of occurrence of preneoplastic proliferation in the kidneys was 100% (14/14); the rate of occurrence of renal tumours was 28.6% (4/14), which included three mesenchymal tumours and one case of renal oncocytoma; the rate of occurrence of extrarenal tumours was 7.1% (1/14), which was a case of mammary duct carcinoma. Renal preneoplastic proliferation and renal tumours, as well as extrarenal tumours, were not observed in control rats during the 6 months. These results differ from previous reports in that tumours originating from both epithelial and mesenchymal tissues were found, which may be attributed to the duration of treatment and the dosage of the drug. These data indicate that AAI administered in an acute manner at high doses does in fact have carcinogenic properties.

    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.

    The in vitro predictive evaluation of chemical carcinogenicity based on hepatic premalignance has so far not been established. Here, we report a novel approach to investigate the premalignant events triggered by human carcinogen aristolochic acid I (AAI) in the liver-like tissue derived from mouse embryonic stem cells. By AAI exposure, the liver-like tissue exhibited the paracrine interleukin-6 phenotypic characteristics. Hepatocytes expressed STAT3/p-STAT3, c-Myc and Lin28B in parallel. Some of them displayed the dedifferentiation characteristics, such as full of α-fetoprotein granules, increase in size, and nucleocytoplasmic shuttle of Oct4. When these cells were injected into mice, the xenografts mostly displayed the uniform area of hepatic-like tissue with malignant nuclei. The hepatic malignant markers, α-fetoprotein, cytokeratin 7 and cytokeratin 19, were co-expressed in albumin-positive areas, respectively. In conclusion, we established an approach to predict the hepatic premalignance triggered by carcinogen AAI. This premalignant assay system might aid to evaluate the effects of potential carcinogens in liver, and probably to screen the protecting against hepatocarcinogenic efficacy of pharmaceuticals in vitro.

    Adult human skin from a sun-protected site (hip) and from a sun-exposed site (forearm) was maintained in organ culture for 12 d in the presence of a serum-free, growth factor-free basal medium. Cultures were incubated under conditions optimized for keratinocyte growth (i.e., in 0.15 mM extracellular Ca2+) or for fibroblast growth (i.e., in 1.4 mM extracellular Ca2+). Treatment with all-trans retinoic acid (RA) induced histological changes in the organ-cultured skin under both conditions which were similar to the changes seen in intact skin after topical application. These included expansion of the viable portion of the epidermis and activation of cells in the dermis. In sun-damaged skin samples, which were characterized by destruction of normal connective tissue elements and presence of thick, dark-staining elastotic fibers, a zone of healthy connective tissue could be seen immediately below the dermo-epidermal junction. This zone was more prominent in RA-treated organ cultures than in matched controls. Associated with these histological changes was an increase in overall protein and extracellular matrix synthesis. In concomitant studies, it was found that RA treatment enhanced survival and proliferation of adult keratinocytes and adult dermal fibroblasts under both low- and high-Ca2+ conditions. In all of these assays, responses of sun-protected and sun-exposed skin were identical. In contrast, responses of neonatal foreskin to RA were similar to those of adult skin in the presence of low-Ca2+ culture medium, but under conditions of high extracellular Ca2+ RA provided little or no additional stimulus. Together these studies suggest that the ability of RA to enhance repair of sun-damaged skin (documented in previous studies) may reflect its ability to influence the behavior of skin in a manner that is age dependent but independent of sun-exposure status.

    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 model 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). The tool is also able to take

  6. When multiple identities interfere: the role of identity centrality.

    2004-04-01

    The current study extends research in the area of identity conflict or interference by focusing on a new identity combination, the woman and scientist identities. In addition, it examines the influence of identity centrality, or importance, as a predictor of interference and moderator of the relation between interference and well-being and science performance. Supporting hypotheses, greater identity interference was related to lower levels of performance and well-being. Furthermore, woman centrality was unrelated to interference for those with a central scientist identity, but for those without a central scientist identity, they were positively related. Although central identities were related to positive outcomes in the absence of interference, the outcomes of all women suffered when interference was high, contrary to the hypothesis. The implications of identity centrality for understanding the negotiation of potentially conflicting identities, and for the retention of women in the sciences, are discussed.

    Aristolochic acids (AAs) are the main bioactive ingredients in the most of Aristolochia plants, which are used to make dietary supplements, slimming pills and Traditional Chinese Medicines (TCMs). Excessive ingestion of AAs can lead to serious nephropathy. Therefore, quantitative analysis and quality control for the plants containing AAs is of great importance. In this paper, capillary electrophoresis (CE) with electrochemical detection (ED) at a 33 microm carbon fiber microdisk electrode (CFE) has been applied to detect AA-I and AA-II in Aristolochia plants. Under the optimum conditions: detection potential at 1.20 V, 2.0 x 10(-2) mol L(-1) phosphate buffer solution (PBS) (pH 10.0), injection time 25 s at a height of 17 cm and separation voltage at 12.5 kV, the AA-I and AA-II were baseline separated within 5 min. Low detection limits for AA-I and AA-II were 4.0 x 10(-8) mol L(-1) and 1.0 x 10(-7) mol L(-1), respectively. Wide linear ranges were from 4.0 x 10(-8) mol L(-1) to 1.9 x 10(-5) mol L(-1) and 1.0 x 10(-7) mol L(-1) to 5.0 x 10(-5) mol L(-1) for AA-I and AA-II, respectively. The proposed method has been successfully applied to analyze AAs contents in plant extracts. The results indicated that the contents of AAs in each part of Aristolochia debilis Sieb. Et Zucc. plant were different. Meanwhile, the CE-ED method was utilized for fingerprint analysis of medicine herbs. Six herbs (Radix aristolochiae, Fructus aristolochiae, Herba aristolochiae, Caulis aristolochiae manshuriensis, Caulis clematidis armandii, Caulis akebiae) were well distinguished by comparing their electropherograms obtained by CE-ED method.

    Quantum entanglement is one of the most prominent features of quantum mechanics and forms the basis of quantum information technologies. Here we present a novel method for the creation of quantum entanglement in multipartite and high-dimensional systems. The two ingredients are (i) superposition of photon pairs with different origins and (ii) aligning photons such that their paths are identical. We explain the experimentally feasible creation of various classes of multiphoton entanglement encoded in polarization as well as in high-dimensional Hilbert spaces-starting only from nonentangled photon pairs. For two photons, arbitrary high-dimensional entanglement can be created. The idea of generating entanglement by path identity could also apply to quantum entities other than photons. We discovered the technique by analyzing the output of a computer algorithm. This shows that computer designed quantum experiments can be inspirations for new techniques.

    2003-10-01

    Recent advances in research on implicit social cognition offer an opportunity to challenge common assumptions about self and identity. In the present article, we critically review a burgeoning line of research on self-related processes known to occur outside conscious awareness or conscious control. Our discussion focuses on these implicit self-related processes as they unfold in the context of social group memberships. That is, we show that group memberships can shape thoughts, preferences, motives, goals, or behaviors without the actor's being aware of such an influence or having control over such expressions. As such, this research brings to the fore facets of the self that often contrast with experiences of reflexive consciousness and introspection. Far from being rigid or monolithic, these processes are highly flexible, context-sensitive, and deeply rooted in socio-structural realities. As such, work on implicit self and identity renew thinking about the interplay between the individual and the collective.

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.

  10. Mass Spectrometric and Spectrofluorometric Studies of the Interaction of Aristolochic Acids with Proteins

    NASA Astrophysics Data System (ADS)

    Li, Weiwei; Hu, Qin; Chan, Wan

    2015-10-01

    Aristolochic acid (AA) is a potent carcinogen and nephrotoxin and is associated with the development of “Chinese herb nephropathy” and Balkan endemic nephropathy. Despite decades of research, the specific mechanism of the observed nephrotoxicity has remained elusive and the potential effects on proteins due to the observed toxicity of AA are not well-understood. To better understand the pharmacotoxicological features of AA, we investigated the non-covalent interactions of AA with proteins. The protein-binding properties of AA with bovine serum albumin (BSA) and lysozyme were characterized using spectrofluorometric and mass spectrometric (MS) techniques. Moreover, the protein-AA complexes were clearly identified by high-resolution MS analyses. To the best of our knowledge, this is the first direct evidence of non-covalently bound protein-AA complexes. An analysis of the spectrofluorometric data by a modified Stern-Volmer plot model also revealed that both aristolochic acid I (AAI) and aristolochic acid II (AAII) were bound to BSA and lysozyme in 1:1 stoichiometries. A significantly stronger protein binding property was observed in AAII than in AAI as evidenced by the spectrofluorometric and MS analyses, which may explain the observed higher mutagenicity of AAII.

  11. 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.

  12. Contextuality of identical particles

    NASA Astrophysics Data System (ADS)

    Kurzyński, Paweł

    2017-01-01

    There exist quantum phenomena that cannot be explained by noncontextual hidden-variable theories, yet the majority of them requires measurements that are performed on a single quantum system at a time. This fact constrains the phenomenon of contextuality to the microscopic domain. It is therefore natural to ask if quantum contextuality can be observed in measurements on collections of particles. Since particles in nature are identical, one can expect that such contextuality would be linked to bosonic and fermionic properties. Analysis of quantum contextuality in such scenarios would broaden our understanding of nonclassical effects in composite systems and perhaps would give us a hint on how to observe quantum phenomena in the macroscopic world. In this work I propose a generalization of quantum contextuality to the case of many identical particles. I show that a type of contextuality exhibited by a collection of particles (state dependent, state independent, or noncontextual) depends on their type and their number. I also discuss further properties of this generalization and identify major open questions.

  13. Online Identities and Social Networking

    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.

  14. Glutamate dehydrogenase requirement for apoptosis induced by aristolochic acid in renal tubular epithelial cells.

    2011-12-01

    Ingestion of aristolochic acids (AA) contained in herbal remedies results in a renal disease and, frequently, urothelial malignancy. The genotoxicity of AA in renal cells, including mutagenic DNA adduct formation, is well-documented. However, the mechanisms of AA-induced tubular atrophy and renal fibrosis are largely unknown. Epithelial cell death is a critical characteristic of these pathological conditions. To elucidate the mechanisms of AA-induced cytotoxicity, we explored AA-interacting proteins in tubular epithelial cells (TEC). We found that AA interacts with a mitochondrial enzyme glutamate dehydrogenase (GDH) and moderately inhibits its activity. We report that AA induces cell death in GDH-knockdown TEC preferentially via non-apoptotic means, whereas in GDH-positive cells, death was executed by both the non-apoptotic and apoptotic mechanisms. Apoptosis is an energy-reliant process and demands higher adenosine 5'-triphosphate (ATP) consumption than does the non-apoptotic cell death. We found that, after AAI treatment, the ATP depletion is more pronounced in GDH-knockdown cells. When we reduced ATP in TEC cells by inhibition of glycolysis and mitochondrial respiration, cell death mode switched from apoptosis and necrosis to necrosis only. In addition, in cells incubated at low glucose and no glutamine conditions, oxaloacetate and pyruvate reduced AAI-induced apoptosis our data suggest that AAI-GDH interactions in TEC are critical for the induction of apoptosis by direct inhibition of GDH activity. AA binding may also induce changes in GDH conformation and promote interactions with other molecules or impair signaling by GDH metabolic products, leading to apoptosis.

    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

    We studied identity development during 5 years in seven deaf adolescents who attended a school for deaf children in the highest level of regular secondary education (age between 14 and 18 years), administering identity interviews every year. Identity development is conceptualized as the processes of exploration and commitment formation (Bosma, 1985). We started from the assumption that because deaf adolescents meet more challenges and also-in our sample-were stimulated in their identity development by school programs, they meet identity conflicts at a relatively early age. The findings were highly consistent with our hypotheses that-compared to a general sample-identity development proceeds faster than in a hearing group and that commitment formation in the domain "Being Deaf" starts earlier than in other domains. We did not find evidence for the hypothesis that commitment formation in this domain in the last year was more mature than in other domains due to a ceiling effect.

    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.

  1. Identity change and informed consent.

    PubMed

    Witt, Karsten

    2017-03-20

    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.

  2. National Development Generates National Identities

    PubMed Central

    2016-01-01

    The purpose of the article is to test the relationship between national identities and modernisation. We test the hypotheses that not all forms of identity are equally compatible with modernisation as measured by Human Development Index. The less developed societies are characterised by strong ascribed national identities based on birth, territory and religion, but also by strong voluntarist identities based on civic features selected and/or achieved by an individual. While the former decreases with further modernisation, the latter may either decrease or remain at high levels and coexist with instrumental supranational identifications, typical for the most developed countries. The results, which are also confirmed by multilevel regression models, thus demonstrate that increasing modernisation in terms of development contributes to the shifts from classical, especially ascribed, identities towards instrumental identifications. These findings are particularly relevant in the turbulent times increasingly dominated by the hardly predictable effects of the recent mass migrations. PMID:26841050

  3. Estimating statistical distributions using an integral identity

    NASA Astrophysics Data System (ADS)

    Zhang, Cheng; Ma, Jianpeng

    2012-05-01

    We present an identity for an unbiased estimate of a general statistical distribution. The identity computes the distribution density from dividing a histogram sum over a local window by a correction factor from a mean-force integral, and the mean force can be evaluated as a configuration average. We show that the optimal window size is roughly the inverse of the local mean-force fluctuation. The new identity offers a more robust and precise estimate than a previous one by Adib and Jarzynski [J. Chem. Phys. 122, 014114 (2005)], 10.1063/1.1829631. It also allows a straightforward generalization to an arbitrary ensemble and a joint distribution of multiple variables. Particularly we derive a mean-force enhanced version of the weighted histogram analysis method. The method can be used to improve distributions computed from molecular simulations. We illustrate the use in computing a potential energy distribution, a volume distribution in a constant-pressure ensemble, a radial distribution function, and a joint distribution of amino acid backbone dihedral angles.

    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. PMID:20593009

  5. Preventing leaf identity theft with hormones.

    PubMed

    Lumba, Shelley; McCourt, Peter

    2005-10-01

    Genetic analysis of plant development has begun to demonstrate the importance of hormone synthesis and transport in regulating morphogenesis. In the case of leaf development, for example, auxin pooling determines where a primordium will emerge and leads to the activation of transcription factors, which determine leaf identities by modulating abscisic acid (ABA) and gibberellic acid (GA) concentrations. Signal transduction studies suggest that negative regulation of transcription factors through protein turnover is commonly used as a mechanism of hormone action. Together, these findings suggest that auxin might degrade a repressor that allows the activation of genes that modulate ABA/GA ratios in emerging leaves. With our increased understanding of the molecular basis of hormone signaling, it is becoming possible to overlay important regulators onto signaling modules that determine morphological outputs.

    We derive quantum field theory Ward identities based on linear area preserving and conformal transformations in 2+1 dimensions. The identities relate Hall viscosities, Hall conductivities and the angular momentum. They apply both for relativistic and non relativistic systems, at zero and at finite temperature. We consider systems with or without translation invariance, and introduce an external magnetic field and viscous drag terms. A special case of the identities yields the well known relation between the Hall conductivity and half the angular momentum density.

  13. Digital Identity - The Legal Person?

    NASA Astrophysics Data System (ADS)

    Sullivan, Clare

    This paper examines the concept of digital identity which the author asserts is now evident in the United Kingdom as a consequence of the Identity Cards Act (UK) 2006 and the National Identity Scheme it establishes. The nature and functions of the concept, particularly the set of information which constitutes an individual’s transactional identity, are examined. The paper then considers the central question of who, or what, is the legal person in a transaction i.e. who or what enters into legal relations. The analysis presents some intriguing results which were almost certainly not envisaged by the legislature. The implications extend beyond the United Kingdom to similar schemes in other jurisdictions, and to countries, like Australia, which may implement such a scheme.

  14. 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

    The potentials of mean force of homodimers of the molecules modeling hydrophobic amino acid side chains (ethane (for alanine), propane (for proline), isobutane (for valine), isopentane (for leucine and isoleucine), ethylbenzene (for phenylalanine), and methyl propyl sulfide (for methionine)) were determined by umbrella-sampling molecular dynamics simulations in explicit water as functions of distance and orientation. Analytical expressions consisting of the Gay-Berne term to represent effective van der Waals interactions and the cavity term derived in paper 1 of this series were fitted to the potentials of mean force. The positions and depths of the contact minima and the positions and heights of the desolvation maxima, including their dependence on the orientation of the molecules, were well represented by the analytical expressions for all systems, which justifies use of such potentials in coarse-grain protein-folding simulations.

  18. Tracing the identity of objects.

    PubMed

    Rips, Lance J; Blok, Sergey; Newman, George

    2006-01-01

    This article considers how people judge the identity of objects (e.g., how people decide that a description of an object at one time, t(0), belongs to the same object as a description of it at another time, t(1)). The authors propose a causal continuer model for these judgments, based on an earlier theory by Nozick (1981). According to this model, the 2 descriptions belong to the same object if (a) the object at t(1) is among those that are causally close enough to be genuine continuers of the original and (b) it is the closest of these close-enough contenders. A quantitative version of the model makes accurate predictions about judgments of which a pair of objects is identical to an original (Experiments 1 and 2). The model makes correct qualitative predictions about identity across radical disassembly (Experiment 1) as well as more ordinary transformations (Experiments 2 and 3).

  19. 'Chronic' identities in mental illness.

    PubMed

    von Peter, Sebastian

    2013-04-01

    The term 'chronicity' is still widely used in psychiatric discourse and practice. A category employed in political, administrative and therapeutic contexts, it guides practitioners' beliefs and actions. This paper attempts a review of the attitudes and procedures that result as a consequence of identifying 'chronically' disturbed identities in clinical practice. An essentially social, relational and materialist understanding of mental illness is used to highlight the kind of thinking underlying the notion of 'chronic' identities in day-to-day psychiatric routines. Problematising the notions of singularity and expressiveness, as well as mind/body- and self/other-distinctions, it claims the category itself is responsible for creating a 'chronic' kind of being. A spatial metaphor is presented in the conclusion, illustrating a mental strategy by which we can re-shape our thinking about 'chronic' identities. It attempts to describe how the shift from an epistemological to a praxeographic approach could build a more complete understanding of mental illness.

  20. Social Trust of Virtual Identities

    NASA Astrophysics Data System (ADS)

    Seigneur, Jean-Marc

    Most other chapters of this book discuss computational models of trust in broader terms, giving definitions of trust, explaining how trust should evolve over time, surveying the different facets of trust .On the other hand, this chapter has a clear focus on the important element of identity in computational trust mechanisms. Trust and reputation are easier to form in face-to-face situations than in situations involving the use of computers and networks because the identity of the trustee is more difficult to verify. In this chapter, the different means to recognise virtual identities are surveyed. Next, their integration into computational trust engines is discussed, especially according to four main requirements: Adaptability, Security, Usability and Privacy (ASUP).

    This paper reviews the ICAO security architecture for biometric passports. An attack enabling RFID identity theft for a later misuse is presented. Specific countermeasures against this attack are described. Furthermore, it is shown that robust high capacity digital watermarking for the embedding and retrieving of binary digital signature data can be applied as an effective mean against RFID identity theft. This approach requires only minimal modifications of the passport manufacturing process and is an enhancement of already proposed solutions. The approach may also be applied in combination with a RFID as a backup solution (damaged RFID chip) to verify with asymmetric cryptographic techniques the authenticity and the integrity of the passport data.

  19. [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.

  13. Identity, causality, and pronoun ambiguity.

    PubMed

    Sagi, Eyal; Rips, Lance J

    2014-10-01

    This article looks at the way people determine the antecedent of a pronoun in sentence pairs, such as: Albert invited Ron to dinner. He spent hours cleaning the house. 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.

    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.

  16. Origins of structural diversity within sequentially identical hexapeptides.

    PubMed Central

    Cohen, B. I.; Presnell, S. R.; Cohen, F. E.

    1993-01-01

    Efforts to predict protein secondary structure have been hampered by the apparent structural plasticity of local amino acid sequences. Kabsch and Sander (1984, Proc. Natl. Acad. Sci. USA 81, 1075-1078) articulated this problem by demonstrating that identical pentapeptide sequences can adopt distinct structures in different proteins. With the increased size of the protein structure database and the availability of new methods to characterize structural environments, we revisit this observation of structural plasticity. Within a set of proteins with less than 50% sequence identity, 59 pairs of identical hexapeptide sequences were identified. These local structures were compared and their surrounding structural environments examined. Within a protein structural class (alpha/alpha, beta/beta, alpha/beta, alpha + beta), the structural similarity of sequentially identical hexapeptides usually is preserved. This study finds eight pairs of identical hexapeptide sequences that adopt beta-strand structure in one protein and alpha-helical structure in the other. In none of the eight cases do the members of these sequences pairs come from proteins within the same folding class. These results have implications for class dependent secondary structure prediction algorithms. PMID:8298461

  19. Affective temperament and personal identity.

    PubMed

    Stanghellini, Giovanni; Rosfort, René

    2010-10-01

    The complex relationship between temperament and personal identity, and between these and mental disorders, is of critical interest to both philosophy and psychopathology. More than other living creatures, human beings are constituted and characterized by the interplay of their genotype and phenotype. There appears to be an explanatory gap between the almost perfect genetic identity and the individual differences among humans. One reason for this gap is that a human being is a person besides a physiological organism. We propose an outline of a theoretical model that might somewhat mitigate the explanatory discrepancies between physiological mechanisms and individual human emotional experience and behaviour. Arguing for the pervasive nature of human affectivity, i.e., for the assumption that human consciousness and behaviour is characterised by being permeated by affectivity; to envisage the dynamics of emotional experience, we make use of a three-levelled model of human personal identity that differentiates between factors that are simultaneously at work in the constitution of the individual human person: 1) core emotions, 2) affective temperament types/affective character traits, and 3) personhood. These levels are investigated separately in order to respect the methodological diversity among them (neuroscience, psychopathology, and philosophy), but they are eventually brought together in a hermeneutical account of human personhood.

    2015-01-01

    Patient: Male, 58 Final Diagnosis: Vasospastic angina Symptoms: Chest pain Medication: — Clinical Procedure: Medical treatment Specialty: Cardiology Objective: Rare disease Background: The clinical conditions of various diseases, including coronary artery disease, are determined by genetics and the environment. Previous investigations noted the significance of genetic mutations and polymorphisms in cases of coronary spasm. Case Report: We report on monozygotic identical twins who almost simultaneously presented with vasospastic angina. The 58-year-old younger twin was admitted to our hospital because of persistent chest pain. An electrocardiogram showed an inverted T wave in the left precordial leads. Coronary angiographies revealed a short left main trunk (LMT) and 50% stenosis at the proximal portion of the left anterior descending artery (LAD). Infusion of acetylcholine to his left coronary artery caused marked vasoconstriction associated with a sensation of chest oppression. Nitroglycerine completely reversed this response. Based on these findings, we diagnosed Twin A with vasospastic angina. At nearly the same time, his identical twin brother was diagnosed with vasospastic angina at another hospital. Comparison of both coronary angiograms indicated similar structure of coronary vessels, including short LMT and mild stenosis at the proximal portion of LAD. Conclusions: These 2 cases highlight the importance of genetic factors in the pathogenesis of vasospastic angina. It may be important for individuals to receive medical attention if their identical twin presents with vasospastic angina. PMID:26347942

    Physician has to know the patient in the disease and not only the disease in the patient, from the dual perspective of the body as object and the body as subject. This also affects the patient who has to cope with the reality of having a body that bursts into the subject's consciousness as a vital threat, as source of discomfort and inability and being a body (Marcel). The human body in its dual aspect has been and is a great unknown, if not a great outrage in spite of the fact that we are our body and our body is each of us. We sometimes do not feel as we are and thus a confrontation arises, sometimes more normal, others more morbid. This forces the physician to face complex ethics considerations and the scientist to accept a personal identity disorder. Dualism considers that there are two substances in us, one that distinguishes us from other beings and from the rest of the individuals of the human species, the soul, the psychic life, mind or consciousness, and another more insubstancial one, the body. The aim of the first substance is to dominate the body, to survive it after death when it is, already a corpse is meant to become putrefied, is buried, incinerated or thrown to the depth of the sea. This dualism aims to explain the origin of the evil and the attitude to defeat it and it does so efficiently. This anthropology has very ancient roots (the Upvanishads, in the orphic texts, in Plato), it is the core of Gnostic thought and the foundation of the modern science since Descartes. Some monist perspectives are a masked dualism or a mereologic fallacy, according to which, the brain is conscious, when that what is conscious is the subject, although the subject, with the brain could not be conscious. Therefore, a new perspective is proposed, chiasmatic or janicular monism, that considers the adaptive value of focusing on the reality from two perspectives, as physical universe and the world of interpersonal relationships.

    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.

  8. Synchronization of two identical and non-identical Rulkov models

    Sun, Huijing; Cao, Hongjun

    2016-11-01

    In this paper, the synchronization of two chaotic Rulkov map-based neurons is taken into account. Firstly, based on the master stability function (MSF) analysis, the complete synchronization of two electrical coupled chaotic Rulkov neurons is investigated in detail. The two-dimensional parameter-space plot that displays directly the values of the MSF in different colors is numerically obtained. The numerical values of the MSF show that the two electrical coupled Rulkov neurons are likely to achieve the complete synchronization when each single neuron is in a silent state or a period-1 bursting state, while are unable to reach the complete synchronous state when each single neuron is in a chaotic bursting state or a spiking state. Secondly, Pearson's correlation coefficient is employed to measure the synchronization degree, which demonstrates the nonexistence of the complete synchronization for non-identical electrical coupled Rulkov neurons. Importantly, the complete synchronization can not be reached with the increase of the electrical coupling strength, which is different from the continuous-time neuronal models. Finally, based on the active control method, a synchronization scheme is presented to study the complete synchronization for two Rulkov neurons no matter whether they are identical or not. The scheme is also applied to investigate the anticipated synchronization and the lag synchronization for any two Rulkov neurons. Numerical simulations verify the correctness of our analytical results and the effectiveness of our methods.

  9. Practicing Identity: A Crafty Ideal?

    NASA Astrophysics Data System (ADS)

    Brysbaert, A.; Vetters, M.

    This paper focuses on the materialization of technological practices as a form of identity expression. Contextual analyses of a Mycenaean workshop area in the Late Bronze Age citadel of Tiryns (Argolis, Greece) are presented to investigate the interaction of different artisans under changing socio-political and economic circumstances. The case study indicates that although certain technological practices are often linked to specific crafts, they do not necessarily imply the separation of job tasks related to the working of one specific material versus another. Shared technological practices and activities, therefore, may be a factor in shaping cohesive group identities of specialized artisans. Since tracing artisans' identities is easier said than done on the basis of excavated materials alone, we employ the concepts of multiple chaînes opératoires combined with cross-craft interactions as a methodology in order to retrieve distinctive sets of both social and technological practices from the archaeological remains. These methodological concepts are not restricted to a specific set of steps in the production cycle, but ideally encompass reconstructing contexts of extraction, manufacture, distribution and discard/reuse for a range of artefacts. Therefore, these concepts reveal both technological practices, and, by contextualising these technological practices in their spatial layout, equally focus on social contacts that would have taken place during any of these actions. Our detailed contextual study demonstrates that the material remains when analysed in their entirety are complementary to textual evidence. In this case study they even form a source of information on palatial spheres of life about which the fragmentary Linear B texts, so far, remain silent.

    We present a case of dissociative identity disorder in which Schneiderian first rank symptoms were present besides of various states of consciousness. Thus the diagnosis of schizophrenia had to be considered. Formally, the symptoms met ICD-10 criteria for schizophrenia. However, taking into account the lack of formal thought disorder and of negative symptoms as well as a typical history of severe and prolonged traumatisation, we did not diagnose a co-morbid schizophrenic disorder. There is good evidence for the existence of psychotic symptoms among patients with dissociative disorders. However, in clinical practice this differential diagnosis is rarely considered.

    PubMed

    Hamilton, Helen

    2005-09-01

    For many new graduates the transition from nursing student to a professional in practice is marked by conflict and tension. Given that conflict may ensue from differing discursive constructions of new graduates, this article reports a review of discursive construction between new graduates from two institutions with vested interests in nursing graduates--comparing health service organisations and educational institutions in Victoria. Four discourses, common to both sets of texts and constitutive of new graduate identity were identified: these were the discourse of nursing practice; the discourse of the good nurse; the discourse of knowing and thinking; and the discourse of statute and regulation. A discourse peculiar to health service organisations only was identified as an organisational and bureaucratic discourse. This review reports the new graduate, as constructed in education texts, as a rational, independent, critically thinking and knowing care giver. In contrast, in health service organisation texts, the new graduate is constructed as a functional, efficient, organisational operative, providing a nursing service. New graduates are concluded to experience multiple discursive dissonances in their first employment which stem from differing constructions of new graduate identity within institutional discourses. If tensions experienced in the transition as discursively generated are understood, previously unthought of ways preparing and introducing nurses to the work place may ensue.

  18. Categorizing identity from facial motion.

    Girges, Christine; Spencer, Janine; O'Brien, Justin

    2015-01-01

    Advances in marker-less motion capture technology now allow the accurate replication of facial motion and deformation in computer-generated imagery (CGI). A forced-choice discrimination paradigm using such CGI facial animations showed that human observers can categorize identity solely from facial motion cues. Animations were generated from motion captures acquired during natural speech, thus eliciting both rigid (head rotations and translations) and nonrigid (expressional changes) motion. To limit interferences from individual differences in facial form, all animations shared the same appearance. Observers were required to discriminate between different videos of facial motion and between the facial motions of different people. Performance was compared to the control condition of orientation-inverted facial motion. The results show that observers are able to make accurate discriminations of identity in the absence of all cues except facial motion. A clear inversion effect in both tasks provided consistency with previous studies, supporting the configural view of human face perception. The accuracy of this motion capture technology thus allowed stimuli to be generated that closely resembled real moving faces. Future studies may wish to implement such methodology when studying human face perception.

  19. Biochemical determinants in Gender identity.

    PubMed

    Hamilton, W; Chapman, P H

    1977-01-01

    The purpose of this communication is to report cognate studies which suggest that the nature of the peripheral metabolism of testosterone may impart gender direction to thought construction and motive. In patients with the complete testicular feminizing syndrome [4], the XO/XY syndrome [4], female trans-sexualism [4] and testicular agenesis [5] HCG-tests of 3 days duration were performed, and plasma and urinary testosterone, urinary excretion of 5 alpha-androstane, 3 alpha, 17 beta-diol (5 alpha-diol), 5 beta-androstane, 3 alpha, 17 beta-diol (5 beta-diol) and epiandrosterone before and after stimulation were measured. In addition steroid transformation was examined by incubation studies with human fetal brain tissue. The results of the latter method presented here are in agreement with published work. It seems clear therefore that the peripheral levels of androgens, oestrogens and their metabolites combine with cerebral steroid transformation, metabolism and possible also synthesis in order to establish gender identity. Exploration of the role of peripheral hormones as stimulators of both gender identity and gender function has dictated the need for a new approach to therapy for gender abnormalities in psyche and soma.

    The present study addresses the relationships of caregiver identity status on their adolescent children's identity distress and psychological symptom severity among a sample of adolescents (age 12-19) in treatment at a community mental health center (N = 60 caregiver-child dyads). A significant proportion of caregivers (10%) and their adolescent children (21.7%) met DSM-IV criteria for Identity Problem. Caregiver identity commitment, significantly predicted adolescent identity distress over and above the adolescents' identity variables, while caregiver identity exploration significantly predicted adolescent psychological symptom severity. These findings and implications are discussed in further detail.

  1. Recognizing Moral Identity as a Cultural Construct

    PubMed Central

    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. PMID:28377737

    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.

  4. Mitochondrial Replacement: Ethics and Identity.

    Wrigley, Anthony; Wilkinson, Stephen; Appleby, John B

    2015-11-01

    Mitochondrial replacement techniques (MRTs) have the potential to allow prospective parents who are at risk of passing on debilitating or even life-threatening mitochondrial disorders to have healthy children to whom they are genetically related. Ethical concerns have however been raised about these techniques. This article focuses on one aspect of the ethical debate, the question of whether there is any moral difference between the two types of MRT proposed: Pronuclear Transfer (PNT) and Maternal Spindle Transfer (MST). It examines how questions of identity impact on the ethical evaluation of each technique and argues that there is an important difference between the two. PNT, it is argued, is a form of therapy based on embryo modification while MST is, instead, an instance of selective reproduction. The article's main ethical conclusion is that, in some circumstances, there is a stronger obligation to use PNT than MST.

    The role of the soul and spirit in the composition of human endeavour generally takes the form of motivational poster catch phrases or third-hand quotes. If the spirit equals the life of a creature, and one of the signs of life is locomotion, are humans not obliged by something even deeper than our humanity to explore the universe? This paper examines the roots and perspectives of our worldviews on identity, exploration, and the limitations and capacities of humanity. It will equip the reader to discuss the nature of exploration with audiences across a wide range of worldviews. Current cultures, regardless of religion or politics, are looped into a series of nihilistic patterns that must be broken by rediscovering our nature as living beings, and our obligations as human beings.

    In this paper we prove the unique existence of a ropelength-minimizing conformation of the θ-spun double helix in a mathematically rigorous way, and find the minimal ropelength {{{Rop}}}* (θ )=-\\tfrac{8π }{t} where t is the unique solution in [-θ ,0] of the equation 2-2\\cos (t+θ )={t}2. Using this result, the pitch angles of the standard, triple and quadruple helices are around 39.3771^\\circ , 42.8354^\\circ and 43.8351^\\circ , respectively, which are almost identical with the approximated pitch angles of the zero-twist structures previously known by Olsen and Bohr. We also find the ropelength of the standard N-helix.

  7. Mitochondrial Replacement: Ethics and Identity

    Wilkinson, Stephen; Appleby, John B.

    2015-01-01

    Abstract Mitochondrial replacement techniques (MRTs) have the potential to allow prospective parents who are at risk of passing on debilitating or even life‐threatening mitochondrial disorders to have healthy children to whom they are genetically related. Ethical concerns have however been raised about these techniques. This article focuses on one aspect of the ethical debate, the question of whether there is any moral difference between the two types of MRT proposed: Pronuclear Transfer (PNT) and Maternal Spindle Transfer (MST). It examines how questions of identity impact on the ethical evaluation of each technique and argues that there is an important difference between the two. PNT, it is argued, is a form of therapy based on embryo modification while MST is, instead, an instance of selective reproduction. The article's main ethical conclusion is that, in some circumstances, there is a stronger obligation to use PNT than MST. PMID:26481204

  8. Positional identity of adult stem cells in salamander limb regeneration.

    Kumar, Anoop; Gates, Phillip B; Brockes, Jeremy P

    2007-01-01

    Limb regeneration in larval and adult salamanders proceeds from a mound of mesenchymal stem cells called the limb blastema. The blastema gives rise just to those structures distal to its level of origin, and this property of positional identity is reset to more proximal values by treatment with retinoic acid. We have identified a cell surface protein, called Prod1/CD59, which appears to be a determinant of proximodistal identity. Prod1 is expressed in an exponential gradient in an adult limb as determined by detection of both mRNA and immunoreactive protein. Prod1 protein is up-regulated after treatment of distal blastemas with RA and this is particularly marked in cells of the dermis. These cells have previously been implicated in pattern formation during limb regeneration.

  9. Stop identity cue as a cue to language identity

    NASA Astrophysics Data System (ADS)

    Castonguay, Paula Lisa

    The purpose of the present study was to determine whether language membership could potentially be cued by the acoustic-phonetic detail of word-initial stops and retained all the way through the process of lexical access to aid in language identification. Of particular interest were language-specific differences in CE and CF word-initial stops. Experiment 1 consisted of an interlingual homophone production task. The purpose of this study was to examine how word-initial stop consonants differ in terms of acoustic properties in Canadian English (CE) and Canadian French (CF) interlingual homophones. The analyses from the bilingual speakers in Experiment 1 indicate that bilinguals do produce language-specific differences in CE and CF word-initial stops, and that closure duration, voice onset time, and burst spectral SD may provide cues to language identity in CE and CF stops. Experiment 2 consisted of a Phoneme and Language Categorization task. The purpose of this study was to examine how stop identity cues, such as VOT and closure duration, influence a listener to identify word-initial stop consonants as belonging to Canadian English (CE) or Canadian French (CF). The RTs from the bilingual listeners in this study indicate that bilinguals do perceive language-specific differences in CE and CF word-initial stops, and that voice onset time may provide cues to phoneme and language membership in CE and CF stops. Experiment 3 consisted of a Phonological-Semantic priming task. The purpose of this study was to examine how subphonetic variations, such as changes in the VOT, affect lexical access. The results of Experiment 3 suggest that language-specific cues, such as VOT, affects the composition of the bilingual cohort and that the extent to which English and/or French words are activated is dependent on the language-specific cues present in a word. The findings of this study enhanced our theoretical understanding of lexical structure and lexical access in bilingual speakers

  10. Ethnic identity, identity coherence, and psychological functioning: testing basic assumptions of the developmental model.

    PubMed

    Syed, Moin; Juang, Linda P

    2014-04-01

    The purpose of the present study was to test three fundamental theoretical propositions from Phinney's (1990) developmental model about the relations among ethnic identity, identity coherence, and psychological functioning: (a) ethnic identity is more strongly related to identity coherence for ethnic minorities than for Whites; (b) ethnic identity is more strongly related to psychological functioning for ethnic minorities than for Whites; and (c) identity coherence mediates the association between ethnic identity and psychological functioning for ethnic minorities, but not for Whites. These hypotheses were tested in three independent samples of ethnically diverse youth. In general, we found weak to moderate support for these three hypotheses, suggesting that the theoretically proposed differences in ethnic identity between ethnic minorities and Whites may not be supported by data. Implications for theory and measurement of ethnic identity are discussed.

    Medical identity theft is a crime with two victims: patients and providers. It is easy to commit and lucrative because healthcare record keeping and business interactions are complex and mainly electronic. Patients whose identity has been stolen are vulnerable to both medical error and financial loss. Providers may suffer both reputation loss and financial loss. There are steps to help prevent and to respond appropriately to medical identity theft.

    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 five times a day for 1 week. Cluster analyses revealed four identity clusters: diffused, foreclosed, moratorium, and 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.

    Some personality psychologists have found a structural symbolic interactionist frame and identity theory relevant to their work. This frame and theory, developed in sociology, are first reviewed. Emphasized in the review are a multiple identity conception of self, identities as internalized expectations derived from roles embedded in organized networks of social interaction, and a view of social structures as facilitators in bringing people into networks or constraints in keeping them out, subsequently, attention turns to a discussion of the mutual relevance of structural symbolic interactionism/identity theory and personality theory, looking to extensions of the current literature on these topics.

    2016-01-01

    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

    An account of James Marcia's identity formation model is given in the language of existentialist philosophy. Parallels between ego-identity and existentialist approaches are examined and identity is described in terms of existentialist concepts formulated by Martin Heidegger (Being and Time) and Jean-Paul Sartre (Being and Nothingness). While identity formation has previously been formulated in terms of ego-analytic theory, this paper argues and seeks to demonstrate that significant benefits accrue from an existentialist account. These benefits include clarification of difficult theoretical issues, delineation of specific research directions and enrichment of clinical understanding.

  17. Dissociative identity disorder: Medicolegal challenges.

    PubMed

    Farrell, Helen M

    2011-01-01

    Persons with dissociative identity disorder (DID) often present in the criminal justice system rather than the mental health system and perplex experts in both professions. DID is a controversial diagnosis with important medicolegal implications. Defendants have claimed that they committed serious crimes, including rape or murder, while they were in a dissociated state. Asserting that their alter personality committed the bad act, defendants have pleaded not guilty by reason of insanity (NGRI). In such instances, forensic experts are asked to assess the defendant for DID and provide testimony in court. Debate continues over whether DID truly exists, whether expert testimony should be allowed into evidence, and whether it should exculpate defendants for their criminal acts. This article reviews historical and theoretical perspectives on DID, presents cases that illustrate the legal implications and controversies of raising an insanity defense based on multiple personalities, and examines the role of forensic experts asked to comment on DID with the goal of assisting clinicians in the medicolegal assessment of DID in relation to crimes.

    2012-01-01

    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.

    2016-12-02

    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.

  9. The crisis of 'identity' in high modernity.

    PubMed

    Bendle, Mervyn F

    2002-03-01

    The concept of 'identity' is central to much contemporary sociology, reflecting a crisis that manifests itself in two ways. Firstly, there is a view that identity is both vital and problematic in this period of high modernity. Secondly, while this awareness is reflected in sociology, its accounts of identity are inconsistent, under-theorized and incapable of bearing the analytical load required. As a result, there is an inherent contradiction between a valuing of identity as so fundamental as to be crucial to personal well-being, and a theorization of 'identity' that sees it as something constructed, fluid, multiple, impermanent and fragmentary. The contemporary crisis of identity thus expresses itself as both a crisis of society, and a crisis of theory. This paper explores the diverse ways in which 'identity' is deployed before turning to case-studies of its use by Anthony Giddens and Manuel Castells. This strategy demonstrates the widespread and diverse concern with identity before exploring how problematic it has become, even in the work of two of the world's leading sociologists.

    2015-10-01

    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.

    PubMed

    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.

  11. Interidentity memory transfer in dissociative identity disorder.

    PubMed

    Kong, Lauren L; Allen, John J B; Glisky, Elizabeth L

    2008-08-01

    Controversy surrounding dissociative identity disorder (DID) has focused on conflicting findings regarding the validity and nature of interidentity amnesia, illustrating the need for objective methods of examining amnesia that can discriminate between explicit and implicit memory transfer. In the present study, the authors used a cross-modal manipulation designed to mitigate implicit memory effects. Explicit memory transfer between identities was examined in 7 DID participants and 34 matched control participants. After words were presented to one identity auditorily, the authors tested another identity for memory of those words in the visual modality using an exclusion paradigm. Despite self-reported interidentity amnesia, memory for experimental stimuli transferred between identities. DID patients showed no superior ability to compartmentalize information, as would be expected with interidentity amnesia. The cross-modal nature of the test makes it unlikely that memory transfer was implicit. These findings demonstrate that subjective reports of interidentity amnesia are not necessarily corroborated by objective tests of explicit memory transfer.

    1971-01-01

    Twelve nonprotein amino acids appear to be present in the Murchison meteorite. The identity of eight of them has been conclusively established as N-methylglycine, β-alanine, 2-methylalanine, α-amino-n-butyric acid, β-amino-n-butyric acid, γ-amino-n-butyric acid, isovaline, and pipecolic acid. 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

  14. Identity development in the late twenties: a never ending story.

    PubMed

    Carlsson, Johanna; Wängqvist, Maria; Frisén, Ann

    2015-03-01

    The aim of this study was to investigate identity development in the late 20s in order to learn more about the continued identity development after identity commitments have been made. The starting point for the study was the contradiction between ideas of identity development as a lifelong process and identity status research showing that stability in identity development is common, particularly so once identity-defining commitments have been made. Identity status interviews were performed with 124 Swedish individuals (63 women) at ages 25 and 29. The 4 identity statuses were equally common at both ages, and stability in identity status between measurements was a typical pattern for individuals assigned to all identity statuses, except moratorium. Longitudinal analysis of interviews from participants assigned to identity achievement, or foreclosure at both occasions, resulted in a model of continued identity development after commitments have been made. The model showed that relevant processes in this identity development are: the ways in which individuals approach changing life conditions, to what extent they continue to engage in meaning making, and how they continue to develop their personal life direction. Identity achievement was connected to continued identity development, whereas developmental patterns connected to foreclosure were more diverse. In conclusion, the study showed that, regardless of identity status change or stability, identity development continues in the late 20s, also beyond identity achievement. Moreover, continued identity development is needed for an established sense of identity to stay adaptive and flexible.

  15. 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 (Mage  = 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.

  16. Identity fusion: the interplay of personal and social identities in extreme group behavior.

    PubMed

    Swann, William B; Gómez, Angel; Seyle, D Conor; Morales, J Francisco; Huici, Carmen

    2009-05-01

    The authors propose that when people become fused with a group, their personal and social identities become functionally equivalent. Two hypotheses follow from this proposition. First, activating either personal or social identities of fused persons should increase their willingness to endorse extreme behaviors on behalf of the group. Second, because personal as well as social identities support group-related behaviors of fused persons, the 2 forms of identity may combine synergistically, fostering exceptionally high levels of extreme behavior. Support for these hypotheses came from 5 preliminary studies and 3 experiments. In particular, fused persons were more willing to fight or die for the group than nonfused persons, especially when their personal or social identities had been activated. The authors conclude that among fused persons, both the personal and social self may energize and direct group-related behavior. Implications for related theoretical approaches and for conceptualizing the relationship between personal identities, social identities, and group processes are discussed.

  17. Ego identity of adolescent children of alcoholics.

    PubMed

    Gavriel-Fried, Belle; Teichman, Meir

    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."

  18. 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.

  19. Ethnic identity of older Chinese in Canada.

    Lai, Daniel W L

    2012-06-01

    In Canada's multicultural society, ethnic identity is important to the elderly and can influence areas such as access to services, health promotion and care. Often, the complex nature of ethnic identity is underestimated when looking at cultural groups. This study aims to: (a) validate the factor structure of a Chinese ethnic identity measure for older Chinese in Canada, (b) examine the level of ethnic identity of the participants, and (c) examine the correlates of ethnic identity in these older individuals. Using data from a large, national research project on the elderly Chinese in Canada, this study analyzed the results gathered from a total of 2,272 participants. Principal component analysis, maximum-likelihood confirmatory factor analysis, and multiple regression analysis were performed. The results indicated that ethnic identity of the older Chinese is a multi-dimensional construct made up of three factors: (a) culture related activities, (b) community ties, (c) linkage with country of origin, and (d) cultural identification. The findings have provided a better understanding of how ethnic identity can be measured among the aging Chinese population in Canada.

    We develop a theory of moral behavior, individual and collective, based on a general model of identity in which people care about “who they are” and infer their own values from past choices. The model sheds light on many empirical puzzles inconsistent with earlier approaches. Identity investments respond nonmonotonically to acts or threats, and taboos on mere thoughts arise to protect beliefs about the “priceless” value of certain social assets. High endowments trigger escalating commitment and a treadmill effect, while competing identities can cause dysfunctional capital destruction. Social interactions induce both social and antisocial norms of contribution, sustained by respectively shunning free riders or do-gooders.

  1. Feynman identity: A special case. I

    SciTech Connect

    da Costa, G.A.

    1997-02-01

    There is an identity due to Feynman which relates graphs and closed curves on a lattice and it was used by Feynman in his combinatorial proof of Onsager{close_quote}s closed formula for the partition function of the two-dimensional Ising model. Long ago Sherman considered a special case of this identity and pointed out similarities with the Witt identity of Lie algebra theory. In this paper and following, we revisit this special case and solve some problems related with it. In particular, the weights are computed explicitly using paths and words and a direct connection with the Witt formula is found. {copyright} {ital 1997 American Institute of Physics.}

  2. Regulation of cellular identity in cancer

    PubMed Central

    Roy, Nilotpal; Hebrok, Matthias

    2015-01-01

    Summary Neoplastic transformation requires changes in cellular identity. Emerging evidence increasingly points to cellular reprogramming, a process during which fully differentiated and functional cells lose aspects of their identity while gaining progenitor characteristics, as a critical early step during cancer initiation. This cell identity crisis persists even at the malignant stage in certain cancers, suggesting that reactivation of progenitor functions supports tumorigenicity. Here, we review recent findings that establish the essential role of cellular reprogramming during neoplastic transformation and the major players involved in it with a special emphasis on pancreatic cancer.

    2009-03-01

    A brief description of the controversies surrounding the diagnosis of dissociative identity disorder is presented, followed by a discussion of the proposed similarities and differences between dissociative identity disorder and borderline personality disorder. The phenomenon of autohypnosis in the context of early childhood sexual trauma and disordered attachment is discussed, as is the meaning of alters or alternate personalities. The author describes recent neurosciences research that may relate the symptoms of dissociative identity disorder to demonstrable disordered attention and memory processes. A clinical description of a typical patient presentation is included, plus some recommendations for approaches to treatment.

    This chapter begins with a discussion of the unique experience of adolescents and emerging adults who grew up with globalization in China and how it has affected their sense of self. We then discuss the effects of globalization on identity development in general, with a special focus on the sociohistorical context of China. We also review and critique the psychological literature that has been conducted on identity within Chinese and Chinese American populations. Finally, we discuss the applicability of Western concepts of identity on a culture that does not necessarily share the same value structure.

  10. 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.

  11. Establishing an Explanatory Model for Mathematics Identity.

    PubMed

    Cribbs, Jennifer D; Hazari, Zahra; Sonnert, Gerhard; Sadler, Philip M

    2015-04-01

    This article empirically tests a previously developed theoretical framework for mathematics identity based on students' beliefs. The study employs data from more than 9,000 college calculus students across the United States to build a robust structural equation model. While it is generally thought that students' beliefs about their own competence in mathematics directly impact their identity as a "math person," findings indicate that students' self-perceptions related to competence and performance have an indirect effect on their mathematics identity, primarily by association with students' interest and external recognition in mathematics. Thus, the model indicates that students' competence and performance beliefs are not sufficient for their mathematics identity development, and it highlights the roles of interest and recognition.

  12. Gender identity and autism spectrum disorders.

    PubMed

    van Schalkwyk, Gerrit I; Klingensmith, Katherine; Volkmar, Fred R

    2015-03-01

    In this review, we briefly summarize much of the existing literature on gender-related concerns and autism spectrum disorders (ASD), drawing attention to critical shortcomings in our current understanding and potential clinical implications. Some authors have concluded that gender identity disorder (GID), or gender dysphoria (GD), is more common in individuals with ASD, providing a range of potential explanations. However, existing literature is quantitatively limited, and our capacity to draw conclusions is further complicated by conceptual challenges regarding how gender identity is best understood. Discourses that emphasize gender as a component of identity formation are gaining prominence and seem particularly salient when applied to ASD. Individuals with ASD should enjoy equal rights with regard to treatment for gender dysphoria. Clinicians may be able to assist individuals in understanding this aspect of their identity by broadening the social frame and facilitating an exploration of gender roles.

  13. Identities in nonlinear realizations of supersymmetry

    NASA Astrophysics Data System (ADS)

    Liu, Haishan; Luo, Hui; Luo, Mingxing; Wang, Liucheng

    2012-11-01

    In this paper, we emphasize that a UV SUSY-breaking theory can be realized either linearly or nonlinearly. Both realizations form the dual descriptions of the UV SUSY-breaking theory. Guided by this observation, we find subtle identities involving the Goldstino field and matter fields in the standard nonlinear realization from trivial ones in the linear realization. Rather complicated integrands in the standard nonlinear realization are identified as total-divergences. Especially, identities only involving the Goldstino field reveal the self-consistency of the Grassmann algebra. As an application of these identities, we prove that the nonlinear Kahler potential without or with gauge interactions is unique, if the corresponding linear one is fixed. Our identities pick out the total-divergence terms and guarantee this uniqueness.

  14. Inquiry identity and science teacher professional development

    NASA Astrophysics Data System (ADS)

    Bryce, Nadine; Wilmes, Sara E. D.; Bellino, Marissa

    2016-06-01

    An effective inquiry-oriented science teacher possesses more than the skills of teaching through investigation. They must address philosophies, and ways of interacting as a member of a group of educators who value and practice science through inquiry. Professional development opportunities can support inquiry identity development, but most often they address teaching practices from limited cognitive perspectives, leaving unexplored the shifts in identity that may accompany teachers along their journey in becoming skilled in inquiry-oriented instruction. In this forum article, we envision Victoria Deneroff's argument that "professional development could be designed to facilitate reflexive transformation of identity within professional learning environments" (2013, p. 33). Instructional coaching, cogenerative dialogues, and online professional communities are discussed as ways to promote inquiry identity formation and collaboration in ways that empower and deepen science teachers' conversations related to personal and professional efficacy in the service of improved science teaching and learning.

    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.

    Identity theft is a serious problem in the United States, and persons with enduring mental illnesses may be particularly vulnerable to becoming victims of this crime. Victims of identity theft experience a variety of consequences that include financial loss and serious emotional distress. Little is known about the impact of identity theft on individuals with mental illnesses. The two cases from a community mental health center presented in this article demonstrate many of the facets that may be associated with an increased risk for becoming the victim of identity theft. A summary of preventive steps as well as steps involved in resolving the crime once one has become a victim are presented. PMID:20806029

    This article is a theoretical study which aims to articulate the notion of narrative identity in the process of aging. This theory makes it possible to present the modalities of figuration of the subject, its broken meanings or refigurations and their elaborated narratives or configurations. The identity narrative explores the mechanisms by which a person develops stories using temporal references, relatives to past and future, and meaningful contexts, to acquire meanings in situations or life stages of disruption and disagreement on whether figuration.

  20. Voice aftereffects of adaptation to speaker identity.

    PubMed

    Zäske, Romi; Schweinberger, Stefan R; Kawahara, Hideki

    2010-09-01

    While adaptation to complex auditory stimuli has traditionally been reported for linguistic properties of speech, the present study demonstrates non-linguistic high-level aftereffects in the perception of voice identity, following adaptation to voices or faces of personally familiar speakers. In Exp. 1, prolonged exposure to speaker A's voice biased the perception of identity-ambiguous voice morphs between speakers A and B towards speaker B (and vice versa). Significantly biased voice identity perception was also observed in Exp. 2 when adaptors were videos of speakers' silently articulating faces, although effects were reduced in magnitude relative to those seen in Exp. 1. By contrast, adaptation to an unrelated speaker C elicited an intermediate proportion of speaker A identifications in both experiments. While crossmodal aftereffects on auditory identification (Exp. 2) dissipated rapidly, unimodal aftereffects (Exp. 1) were still measurable a few minutes after adaptation. These novel findings suggest contrastive coding of voice identity in long-term memory, with at least two perceptual mechanisms of voice identity adaptation: one related to auditory coding of voice characteristics, and another related to multimodal coding of familiar speaker identity.

    2006-09-01

    The research reported here contributes to understanding how student engineers on an engineering campus in the US mid-continent not only talked about the kinds of people recognized as engineers on campus, but also juxtaposes their talk about "campus engineer identities" with two students' ways of presenting themselves as engineers through engineering project teamwork to argue that campus engineer identities framed on-campus interpretations of actions, and ultimately that identity production was a complicated process through which campus engineer identities (cultural knowledge learned on campus) provided a lens of meaning through which to "recognize" (or not) performances of engineer selves as engineers. This research adds to conversations about identity in practice, especially identity production in science education, by suggesting the importance of cultural forms for belonging, especially at an obdurate site of science practice like the campus studied.

    2013-04-01

    The present study was designed to ascertain the extent to which dimensions of acculturation would differ across personal identity statuses in a sample of 2,411 first- and second-generation, immigrant, college-attending emerging adults. Participants from 30 colleges and universities around the United States completed measures of personal identity processes, as well as of heritage and American cultural practices, values, and identifications. Cluster-analytic procedures were used to classify participants into personal identity statuses based on the personal identity processes. Results indicated that, across ethnic groups, individuals in the achieved and searching moratorium statuses reported the greatest endorsement of heritage and American cultural practices, values, and identifications; and individuals in the carefree diffusion status reported the lowest endorsement of all the cultural variables under study. These results are discussed in terms of the convergence between personal identity and cultural identity processes.

  4. Characteristics of place identity as part of professional identity development among pre-service teachers

    2016-12-01

    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.

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

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

    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.

    Moguillansky, Rodolfo

    2013-01-01

    The author stands that the assumption of identity in adolescence questions the identity supports acquired in the family which subjective the adolescent and goes on saying that to affirm her/his identity she/he has to "des-identify" from those identifications that turned her/him into the subject she/he is. The identification process -when instituting her/him as a subject- freezes her/his psyche in a "for ever". On the opposite, the "des-identification" process, necessary for the constitution of the adolescent's identity, releases the Id from the "for ever", it also releases from the life history that alienates her/him and becomes the condition that enables the Id not to go on with the "for ever" and to build a future. This "des-identification" is motorized by the adolescent's need of not going on to be "through her/his parents" and to become herself/himself. To state the role of the family in the identifying process of an adolescent the author refers to: 1-Family and Psychoanalysis. 2-The contributions on "Family and Schizophrenia". 3-The description of different types of families according to the possibility to tolerate the processes of acquiring "otherness", necessary to institute adolescent identity.

  7. Identity and Its Construal: Learning from Luxembourg.

    PubMed

    Murdock, Elke

    2017-03-07

    This article examines national identity construal processes within the case study context of Luxembourg. Building on research highlighting the modalities of generalization from case studies, I present the country case that is Luxembourg. This social universe has a foreign population percentage of 47% and what is considered majority and minority becomes increasingly fluid. The migration process itself is fluid, ranging from daily migration, to medium-term stays, return visits and permanent immigration including uptake of citizenship. Within such a fluid environment, where national borders are permeable at the physical level of crossing borders and (national) societies are nested within societies, culture contact is a permanent feature in daily life. Nationality becomes a salient feature as culture contact tends to prompt reflection, resulting in questioning and (re-)negotiation of national identity. This affects the native population as well as the diverse immigrant population - with diversity going beyond the level of country of origin. Many individuals are also of mixed nationality and some examples for the construal process of national identity will be provided, illustrating how national identity is negotiated at individual level. Like a periscope, this country let s us adjust mirrors, permitting us to observe modes of identity construal which would otherwise be obstructed from the field of view. The case study that is Luxembourg allows us to look at the micro-setting of the construction, potentially of something new.

    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.

    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.

  3. Subjective adult identity and casual sexual behavior

    PubMed Central

    Lyons, Heidi Ann

    2015-01-01

    A majority of Americans have a casual sexual experience before transitioning to adulthood. Little research has yet to examine how identity influences causal sexual behavior. The current study fills this gap in the literature by examining if subjective adult identity predicts casual sexual behavior net of life course transitions in a national sample of Americans. To answer this research question, the Longitudinal Study of Adolescent to Adult Health is utilized. Structural equation modeling results show the older and more adult-like individuals feel the less likely they are to report a recent casual sexual partner. Once life course factors are included in the model, subjective identity is no longer associated with casual sex.

    Adolescence is a complex biopsychosocial phenomenon. All the inner-subjective changes in adolescents take place within the context of a specific social environment, which offers the necessary ideological setting that adolescents must confront in the course of their identity formation. Forced migration creates conditions under which the adolescent Ego may be traumatized more easily, resulting in the development of defensive mechanisms, which may interfere with the natural process of identity formation. The aim of this paper is to investigate how a traumatic situation such as forced migration may affect the mechanisms of identity formation in adolescence. For this purpose, clinical material, consisting of two cases of psychoanalytical psychotherapy of adolescents who were forced to immigrate to Greece, is presented and discussed in a psychoanalytical theoretical framework, along with the historical-sociological background.

  5. Acculturative dissonance, ethnic identity, and youth violence.

    Studies suggest that the process of acculturation for immigrant youth, particularly for second-generation youth, is significantly associated with delinquency and violence. This study explored the acculturation-violence link with respect to acculturative dissonance and ethnic identity. The results revealed in a sample of 329 Chinese, Cambodian, Mien/Laotian, and Vietnamese youth that acculturative dissonance was significantly predictive of serious violence, with full mediation through peer delinquency. Ethnic identity was not significantly associated with peer delinquency or serious violence. Although acculturative dissonance and ethnic identity accounted for a small percentage of variance in violence compared with peer delinquency, it cannot be discounted as trivial. Structural equation analyses provided support for both measurement and structural invariance across the four ethnic groups, lending support for cross-cultural comparisons. The results also lend support for the inclusion of cultural factors in youth violence prevention and intervention efforts.

  6. Shared identity is key to effective communication.

    The ability to communicate with others is one of the most important human social functions, yet communication is not always investigated from a social perspective. This research examined the role that shared social identity plays in communication effectiveness using a minimal group paradigm. In two experiments, participants constructed a model using instructions that were said to be created by an ingroup or an outgroup member. Participants made models of objectively better quality when working from communications ostensibly created by an ingroup member (Experiments 1 and 2). However, this effect was attenuated when participants were made aware of a shared superordinate identity that included both the ingroup and the outgroup (Experiment 2). These findings point to the importance of shared social identity for effective communication and provide novel insights into the social psychology of communication.

  7. Subjective adult identity and casual sexual behavior.

    PubMed

    2015-12-01

    A majority of Americans have a casual sexual experience before transitioning to adulthood. Little research has yet to examine how identity influences causal sexual behavior. The current study fills this gap in the literature by examining if subjective adult identity predicts casual sexual behavior net of life course transitions in a national sample of Americans. To answer this research question, the Longitudinal Study of Adolescent to Adult Health is utilized. Structural equation modeling results show the older and more adult-like individuals feel the less likely they are to report a recent casual sexual partner. Once life course factors are included in the model, subjective identity is no longer associated with casual sex. Practitioners who work with adult populations need to consider how life course transitions influence casual sexual behavior.

  8. Identity Theft: A Study in Contact Centres

    NASA Astrophysics Data System (ADS)

    Moir, Iain; Weir, George R. S.

    This paper explores the recent phenomenon of identity theft. In particular, it examines the contact centre environment as a mechanism for this to occur. Through a survey that was conducted amongst forty-five contact centre workers in the Glasgow area we determined that contact centres can and do provide a mechanism for identity theft. Specifically, we found a particularly high incidence of agents who had previously dealt with phone calls that they considered suspicious. Furthermore, there are agents within such environments who have previously been offered money in exchange for customers' details, or who know of fellow workers who received such offers. Lastly, we identify specific practices within contact centres that may contribute to the likelihood of identity theft.

  9. Penile malformation, gender identity and sexual orientation.

    PubMed

    Berg, R; Berg, G

    1983-09-01

    Gender identity and sexual orientation were investigated in 34 men operated for hypospadias in childhood and in 36 matched control subjects. Independent psychiatric assessments from semi-structured interviews, and double-blind formalized psychological ratings from the Rorschach, yielded similar findings. The probands were less secure in their maleness but were similar in sexual orientation as compared to the controls. A third blind, independent measure of unconscious gender identity, the Franck Drawing Completion Test, gave further evidence of uncertain gender identity in the patients. A self-administered inventory, the Gough Femininity Scale, showed a tendency for the patients to take more feminine sex roles. The findings are discussed from psychoendocrinological as well as psycho-analytical view points. The need for early psychological preventive measures for hypospadic boys and their parents is stressed.

  10. The subjective brain, identity, and neuroethics.

    PubMed

    Gillett, Grant R

    2009-09-01

    The human brain is subjective and reflects the life of a being-in-the-world-with-others whose identity reflects that complex engaged reality. Human subjectivity is shaped and in-formed (formed by inner processes) that are adapted to the human life-world and embody meaning and the relatedness of a human being. Questions of identity relate to this complex and dynamic reality to reflect the fact that biology, human ecology, culture, and one's historic-political situation are inscribed in one's neural network and have configured its architecture so that it is a unique and irreplaceable phenomenon. So much is a human individual a relational being whose own understanding and ownership of his or her life is both situated and distinctive that neurophilosophical conceptions of identity and human activity that neglect these features of our being are quite inadequate to ground a robust neuroethics.

  11. Aboriginal fractions: enumerating identity in Taiwan.

    PubMed

    Liu, Jennifer A

    2012-01-01

    Notions of identity in Taiwan are configured in relation to numbers. I examine the polyvalent capacities of enumerative technologies in both the production of ethnic identities and claims to political representation and justice. By critically historicizing the manner in which Aborigines in Taiwan have been, and continue to be, constructed as objects and subjects of scientific knowledge production through technologies of measuring, I examine the genetic claim made by some Taiwanese to be "fractionally" Aboriginal. Numbers and techniques of measuring are used ostensibly to know the Aborigines, but they are also used to construct a genetically unique Taiwanese identity and to incorporate the Aborigines within projects of democratic governance. Technologies of enumeration thus serve within multiple, and sometimes contradictory, projects of representation and knowledge production.

  12. Multipartite concurrence for identical-fermion systems

    We study the problem of detecting multipartite entanglement among indistinguishable fermionic particles. A multipartite concurrence for pure states of N identical fermions, each one having a d -dimensional single-particle Hilbert space, is introduced. Such an entanglement measure, in particular, is optimized for maximally entangled states of three identical fermions that play a role analogous to the usual (qubit) Greenberger-Horne-Zeilinger state. In addition, it is shown that the fermionic multipartite concurrence can be expressed as the mean value of an observable, provided two copies of the composite state are available.

  13. Mirror writing and a dissociative identity disorder.

    Le, Catherine; Smith, Joyce; Cohen, Lewis

    2009-01-01

    Individuals with dissociative identity disorder (DID) have been known to show varied skills and talents as they change from one dissociative state to another. For example, case reports have described people who have changed their handedness or have spoken foreign languages during their dissociative states. During an interview with a patient with DID, a surprising talent emerged when she wrote a sentence for the Folstein Mini-Mental State Exam-mirror writing. It is not known whether her mirror writing had a deeper level of meaning; however, it does emphasize the idiosyncratic nature of dissociative identity disorder.

    2014-01-01

    Cancer stigma has undergone an important transformation in recent decades. In general, this disease no longer fits squarely into Goffman’s classic taxonomy of stigmatized conditions. This review will demonstrate that, with important adaptations, an identity-threat model of stigma can be used to organize cancer stigma research post-Goffman. This adapted model postulates that one’s personal attributions, responses to situational threat, and disease/treatment characteristics can be used to predict identity threat and well-being of individuals with cancer. Implications for further research and clinical practice are discussed. PMID:28070343

  2. Universality of Schmidt decomposition and particle identity

    PubMed Central

    Sciara, Stefania; Lo Franco, Rosario; Compagno, Giuseppe

    2017-01-01

    Schmidt decomposition is a widely employed tool of quantum theory which plays a key role for distinguishable particles in scenarios such as entanglement characterization, theory of measurement and state purification. Yet, its formulation for identical particles remains controversial, jeopardizing its application to analyze general many-body quantum systems. Here we prove, using a newly developed approach, a universal Schmidt decomposition which allows faithful quantification of the physical entanglement due to the identity of particles. We find that it is affected by single-particle measurement localization and state overlap. We study paradigmatic two-particle systems where identical qubits and qutrits are located in the same place or in separated places. For the case of two qutrits in the same place, we show that their entanglement behavior, whose physical interpretation is given, differs from that obtained before by different methods. Our results are generalizable to multiparticle systems and open the way for further developments in quantum information processing exploiting particle identity as a resource. PMID:28333163

  9. Identical particle model on biophoton emission

    NASA Astrophysics Data System (ADS)

    Liu, T. C.; Liu, Songhao; Popp, Fritz A.; Tang, Ao-Qing

    1996-09-01

    Biophoton emission (PE) method is a non-invasive way revealing biophysical interactions in living tissues. Since its mechanism is not very clear, its acceptance is limited. Gu has presented the quantum theory on biophoton emission according to the Dicke model. However, the Dicke model does not apply to biological system. In this paper, we studied PE by using the identical particle model, the interaction of identical particles by quantum chemistry, as well as the transition of the system interacting with radiation by the time quantum theory on radiation-matter interaction put forward by the first author and his cooperators. It was shown that the identical particles form coherent states, the photon emission probability of the superradiant state is a liner function of N and N2, and the one of the subradiant state is zero. In other words, the photon emission intensity represents the coherent states of the identical particle system. The linear relationship of N and N2 agrees with the PE experiment results on early drosophila embryos. The research on the cell division cycle showed that the superradiant states correspond to the late S phase. This is why PE can be used to differentiate human tumor tissues from normal ones. We also studied induced PE.

  12. Autobiographical memory specificity in dissociative identity disorder.

    PubMed

    Huntjens, Rafaële J C; Wessel, Ineke; Hermans, Dirk; van Minnen, Agnes

    2014-05-01

    A lack of adequate access to autobiographical knowledge has been related to psychopathology. More specifically, patients suffering from depression or a history of trauma have been found to be characterized by overgeneral memory, in other words, they show a relative difficulty in retrieving a specific event from memory located in time and place. Previous studies of overgeneral memory have not included patients with dissociative disorders. These patients are interesting to consider, as they are hypothesized to have the ability to selectively compartmentalize information linked to negative emotions. This study examined avoidance and overgeneral memory in patients with dissociative identity disorder (DID; n = 12). The patients completed the autobiographical memory test (AMT). Their performance was compared with control groups of posttraumatic stress disorder (PTSD) patients (n = 26), healthy controls (n = 29), and DID simulators (n = 26). Specifically, we compared the performance of separate identity states in DID hypothesized to diverge in the use of avoidance as a coping strategy to deal with negative affect. No significant differences in memory specificity were found between the separate identities in DID. Irrespective of identity state, DID patients were characterized by a lack of memory specificity, which was similar to the lack of memory specificity found in PTSD patients. The converging results for DID and PTSD patients add empirical evidence for the role of overgeneral memory involved in the maintenance of posttraumatic psychopathology.

  14. Semiotics of Identity: Politics and Education

    ERIC Educational Resources Information Center

    Szkudlarek, Tomasz

    2011-01-01

    In this text I concentrate on semiotic aspects of the theory of political identity in the work of Ernesto Laclau, and especially on the connection between metaphors, metonymies, catachreses and synecdoches. Those tropes are of ontological status, and therefore they are of key importance in understanding the discursive "production" of…

    Background: All health professionals are responsible for facilitating empowerment among people with diabetes. However, research suggests that health professionals do not have the knowledge and skills to help people with diabetes become empowered. As a result, many Iranian people with diabetes do not become empowered. The aim of the study was to explore and understand how empowerment occurs in Iranian people with diabetes. Materials and Methods: Grounded theory using individual open in-depth interviews, field notes, and memos was used to collect data from 25 people with diabetes, their families, and health professionals. Strauss and Corbin's constant comparative analysis was used to analyze the data. Findings: Empowerment is a transitional, perceptual, and continuous process. The process for people with diabetes includes threatened identity when diabetes is diagnosed, reconstructing identity, and integrating diabetes into identity to become an empowered person with diabetes. The empowerment process was influenced by a combination of knowledge, social support, values and beliefs, psychosocial issues, and the nature of diabetes. Conclusions: Health professionals can help people with diabetes integrate diabetes into their identity and become empowered; however, becoming empowered is complicated and occurs over time.

  16. Universality of Schmidt decomposition and particle identity

    NASA Astrophysics Data System (ADS)

    Sciara, Stefania; Lo Franco, Rosario; Compagno, Giuseppe

    2017-03-01

    Schmidt decomposition is a widely employed tool of quantum theory which plays a key role for distinguishable particles in scenarios such as entanglement characterization, theory of measurement and state purification. Yet, its formulation for identical particles remains controversial, jeopardizing its application to analyze general many-body quantum systems. Here we prove, using a newly developed approach, a universal Schmidt decomposition which allows faithful quantification of the physical entanglement due to the identity of particles. We find that it is affected by single-particle measurement localization and state overlap. We study paradigmatic two-particle systems where identical qubits and qutrits are located in the same place or in separated places. For the case of two qutrits in the same place, we show that their entanglement behavior, whose physical interpretation is given, differs from that obtained before by different methods. Our results are generalizable to multiparticle systems and open the way for further developments in quantum information processing exploiting particle identity as a resource.
