Attachment Behaviors, Depression, and Anxiety in Nonoffending Mothers of Child Sexual Abuse Victims

The purpose of this study was to examine the psychological well-being and attachment behavior of nonoffending mothers of child sexual abuse victims (CSAVs). This topic is significant because it is the mothers who most often provide support for young child victims. Two sets of data on maternal depression, state and trait anxiety, and Ainsworth's maternal attachment behaviors were analyzed. First, 38 mothers of CSAVs were compared based on the presence or absence of maternal history of abuse. Second, from the original 38 mothers of CSAVs, 27 mothers were compared to a matched group of mothers of nonabused children. Children in both data sets were 6 to 48 months. In the first data set, there were no significant differences in depression, anxiety, and attachment behaviors based on mothers' personal history of abuse. However, in the second data set, mothers of CSAVs had heightened levels of depression and anxiety and diminished maternal attachment behaviors.
Use of Online Social Networking Services from a Theoretical Perspective of the Motivation-Participation-Performance Framework

: Social networking services (SNS) are platforms to form and manage personal connections and create a foundation for human relationships. Intending to identify why, how, and for what outcome users use SNS, this study contributes to the body of knowledge on SNS by analyzing how motivation, participation, and performance are related to each other in the SNS context. Drawing on a theoretical perspective of the motivation-participation-performance framework, we identify four significant why motivations (i.e., vertical social, horizontal social, hedonic, and utilitarian motivations), two main ways (how) of participation (i.e., sharing and collaboration), and two ultimate benefits (for what outcome) of SNS use (i.e., personal and job performance). The analyzed results of empirical data collected from SNS users indicate that the identified motivations significantly influence participation in sharing and collaboration activities on SNS and that SNS participation significantly affects personal and professional/job-related performance. This study contributes to theory by providing a multidimensional view of SNS use, its predictors, and its consequences.
Do birds of a feather universally flock together? Cultural variation in the similarity-attraction effect

Three experiments explored the similarity-attraction effect (SAE) among North American and Japanese samples. In all studies, North Americans showed a significantly more pronounced SAE than the Japanese. The North Americans consistently revealed a strong SAE whereas the Japanese effect was only significant in the methods with the most power. The cultural differences emerged across different methods, and for the domains of personality, activities, attitudes and demographics. The cultural difference was mediated by self-esteem, indicating that a motivation for positive self-views is a mechanism underlying the SAE.
Number and spatial distribution of nuclei in the muscle fibres of normal mice studied in vivo

We present here a new technique with which to visualize nuclei in living muscle fibres in the intact animal, involving injection of labelled DNA into single cells. This approach allowed us to determine the position of all of nuclei within a sarcolemma without labelling satellite cells. In contrast to what has been reported in tissue culture, we found that the nuclei were immobile, even when observed over several days. Nucleic density was uniform along the fibre except for the endplate and some myotendinous junctions, where the density was higher. The perijunctional region had the same number of nuclei as the rest of the fibre. In the extensor digitorum longus (EDL) muscle, the extrajunctional nuclei were elongated and precisely aligned to the long axis of the fibre. In the soleus, the nuclei were rounder and not well aligned. When comparing small and large fibres in the soleus, the number of nuclei varied approximately in proportion to cytoplasmic volume, while in the EDL the number was proportional to surface area. Statistical analysis revealed that the nuclei were not randomly distributed in either the EDL or the soleus. For each fibre, actual distributions were compared with computer simulations in which nuclei were assumed to repel each other, which optimizes the distribution of nuclei with respect to minimizing transport distances. The simulated patterns were regular, with clear row‐like structures when the density of nuclei was low. The non‐random and often row‐like distribution of nuclei observed in muscle fibres may thus reflect regulatory mechanisms whereby nuclei repel each other in order to minimize transport distances.
Coagulation profile in diabetes and its association with diabetic microvascular complications.

OBJECTIVES To investigate the haemostatic parameters and to assesss their relationship with microvascular complications in type 2 diabetes mellitus. MATERIALS AND METHODS Coagulation and fibrinolysis parameters were measured in 60 type 2 diabetic patients (M:F 1:1) with (n=40) and without (n=20) diabetic microvascular complications and in 30 nondiabetic healthy subjects (M:F 1:1). RESULTS The mean age of diabetic patients and healthy controls was 56.9 +/- 8.78 and 53.2 +/- 7.58 respectively (p = 0.05). The plasma levels of PAI-1 (22.6 +/- 6.85 vs 44.8 +/- 20.8, p = 0.00), serum fibrinogen (227.5 +/- 22.8 vs. 252.75 +/- 40.23, p = 0.002) and vWF activity (99.4 +/- 28.18 vs. 144.78 +/- 36.21, p = 0.00) were found to be increased in diabetics compared to healthy controls. Plasma PAI-1 levels (37.15 +/- 15.18 vs 48.65 +/- 22.29, p = 0.0) and vWF activity (123.19 +/- 29.63 vs. 155.57 +/- 34.61, p = 0.007) were significantly increased in diabetic patients with microvascular complications than those without microvascular complications.Amongst the diabetic patients, protein S activity (63.05 +/- 16.85 vs. 51.59 +/- 10.7, p = 0.002) was significantly lower in patients with microvascular complications than in patients without these complications. Diabetic retinopathy was associated with decreased protein S levels (63.05 +/- 16.85 vs. 48.48 +/- 8.72, p = 0.005) and vWF activity (123.19 +/- 29.63 vs. 151.85 +/- 29.74, p = 0.009). Diabetic nephropathy was associated with increased PAI-1 levels (39.55 +/- 13.20 vs. 51.69 +/- 26.53, p = 0.02) and vWF activity (134.99 +/- 32.54 vs. 157.57 +/- 37.37, p = 0.007). Diabetic neuropathy did not show any significant relationship with any of the haemostatic variables. CONCLUSION Hypercoagulable state as indicated by decreased fibrinolysis and increased coagulability is responsible as one of the factors for the development of microvascular complications of diabetes mellitus.
Occupational skin diseases among dental nurses

Out of 923 female dental nurses in the Helsinki district, 799 were interviewed using a computer‐assisted telephone interview. A structured questionnaire was used to inquire about skin, respiratory symptoms, atopy, work history and methods, and exposure at work. The 328 nurses, who reported work‐related dermatitis on their hands, forearms or face, were invited to an interview by an occupational physician; 245 nurses participated. 31 nurses had previously been diagnosed with an occupational skin disease (OSD). 133 nurses with a suspected OSD were selected for further clinical examinations with prick and patch testing. Among the 107 nurses examined, 22 new cases of OSD were diagnosed. There were altogether 29 cases of allergic contact dermatitis, 15 of contact urticaria, 12 of irritant contact dermatitis, and 1 case of onychomycosis. Rubber chemicals and natural rubber latex (NRL) in protective gloves, as well as dental‐restorative plastic materials [(meth)acrylates], were the most common causes of allergy. 42% of the OSD cases in the studied population had been missing from the statistics (Finnish Register of Occupational Diseases). Plastic gloves or NRL gloves with a low‐protein content are recommended for dental work. Skin exposure to (meth)acrylates should be avoided.
Plane detection in disparity space

We report an algorithm for detecting planes from disparity maps, without computing 3D information explicitly. Camera calibration is not assumed unless Euclidean plane parameters are required. The algorithm identifies co-planar image patches, thus providing a useful tools in the presence of occlusions. The basic components are a closed-form expression for the disparity of a plane, and a Hough-like voting scheme for plane identification. Experimental results with real data suggest promising performance, comparable with that of recently reported plane detection methods.
Quantitative Evaluation of the Determinants of Export and FDI: Firm-Level Evidence from Japan

Using firm-level data for Japan, this paper examines the determinants of the export and foreign direct investment (FDI) decision. We contribute to the literature by employing a mixed logit model, i.e. a multinomial logit model with random intercepts and random coefficients, to incorporate any unobserved firm heterogeneity and by paying special attention to the quantitative significance of the determinants. We find that while the impact of productivity on the export and FDI decision is positive and statistically significant, it is economically negligible. The effect of firm size, credit constraints and information spillovers from experienced firms is also small in magnitude. A quantitatively dominant determinant of the export and FDI decision is instead the prior status of firms in terms of internationalisation. In addition, the use of the mixed logit model enables us to find a substantial role of unobserved firm characteristics in internationalisation of the firm. These findings suggest that entry costs to foreign markets, which substantially vary in size across firms, play an important role in the export and FDI decision. In addition, given that the negligible effect of productivity and the dominant effect of prior status appear to be more prominent in Japan than in some other countries, this study helps highlight the uniqueness of Japanese firms.

HPLC Separation of Diastereomers: Chiral Molecular Tools Useful for the Preparation of Enantiopure Compounds and Simultaneous Determination of Their Absolute Configurations

To obtain enantiopure compounds, the so-called chiral high performance liquid chromatography (HPLC) method, i.e., HPLC using a chiral stationary phase, is very useful, as reviewed in the present Special Issue. On the other hand, normal HPLC (on silica gel) separation of diastereomers is also useful for the preparation of enantiopure compounds and also for the simultaneous determination of their absolute configurations (ACs). The author and coworkers have developed some chiral molecular tools, e.g., camphorsultam dichlorophthalic acid (CSDP acid), 2-methoxy-2-(1-naphthyl)propionic acid (MαNP acid), and others suitable for this purpose. For example, a racemic alcohol is esterified with (S)-(+)-MαNP acid, yielding diastereomeric esters, which are easily separable by HPLC on silica gel. The ACs of the obtained enantiopure MαNP esters can be determined by the 1H-NMR diamagnetic anisotropy method. In addition, MαNP or CSDP esters have a high probability of giving single crystals suitable for X-ray crystallography. From the X-ray Oak Ridge thermal ellipsoid plot (ORTEP) drawing, the AC of the alcohol part can be unambiguously determined because the AC of the acid part is already known. The hydrolysis of MαNP or CSDP esters yields enantiopure alcohols with the established ACs. The mechanism and application examples of these methods are explained.
Generating stereochemically acceptable protein pathways

We describe a new method for rapidly generating stereochemically acceptable pathways in proteins. The method, called geometric targeting, is publicly available at the webserver http://pathways.asu. edu, and includes tools for visualization of the pathway and creating movie files for use in presentations. The user submits an initial structure and a target structure, and a pathway between the two input states is generated automatically. Besides visualization, the structural quality of the pathways makes them useful as input pathways into pathway refinement techniques and further computations. The approach in geometric targeting is to gradually change the system's RMSD relative to the target structure while enforcing a set of geometric constraints. The generated pathways are not minimum free energy pathways, but they are geometrically plausible pathways that maintain good covalent bond distances and angles, keep backbone dihedral angles in allowed Ramachandran regions, avoid eclipsed side‐chain torsion angles, avoid non‐bonded overlap, and maintain a set of hydrogen bonds and hydrophobic contacts. Resulting pathways for over 20 proteins featuring a wide variety of conformational changes are reported here, including the very large GroEL complex. Proteins 2010. © 2010 Wiley‐Liss, Inc.
Epigenetic memory in plants

Epigenetics refers to heritable changes in patterns of gene expression that occur without alterations in DNA sequence. The epigenetic mechanisms involve covalent modifications of DNA and histones, which affect transcriptional activity of chromatin. Since chromatin states can be propagated through mitotic and meiotic divisions, epigenetic mechanisms are thought to provide heritable ‘cellular memory’. Here, we review selected examples of epigenetic memory in plants and briefly discuss underlying mechanisms.
Web-data augmented language models for Mandarin conversational speech recognition

Lack of data is a problem in training language models for conversational speech recognition, particularly for languages other than English. Experiments in English have successfully used Web-based text collection, targeted for a conversational style, to augment small sets of transcribed speech; we look at extending these techniques to Mandarin. In addition, we investigate different techniques for topic adaptation. Experiments in recognizing Mandarin telephone conversations show that the use of filtered Web data leads to a 28% reduction in perplexity and 7% reduction in character error rate, with most of the gain due to the general filtered Web data.

Current Status of Antibiograms of Listeria ivanovii and Enterobacter cloacae Isolated from Ready-To-Eat Foods in Alice, South Africa

This study assessed the antimicrobial susceptibility of 51 Listeria ivanovii and 33 Enterobacter cloacae strains isolated from various ready-to-eat foods sold in Alice, South Africa. Isolates were identified using standard microbiological tests and further confirmed using API 20E and API Listeria kits. The disc diffusion technique was used to screen for antimicrobial susceptibility against 15 antimicrobials; minimum inhibitory concentration of five antibiotics was determined by the broth dilution method. All the strains of E. cloacae (100%) and 96% of L. ivanovii isolates were resistant to at least four or more of the antibiotics; nineteen antibiotypes were obtained based on the antibiotics used in the study. Antibiotype A5: AR PGR VAR ER APR was predominant in both L. ivanovii (23.5%) and E. cloacae (57.5%) isolates. Marked susceptibility of Listeriaivanovii was observed against chloramphenicol, ciprofloxacin, streptomycin and trimethoprim/sulfamethoxazole (100%) each while E. cloacae registered 100% susceptibility to ciprofloxacin only. Various percentages of susceptibility was reported to chloramphenicol and gentamicin (91%) each, nalidixic acid (97%) and streptomycin (94%). The MIC90 ranged from 0.004–7.5 µg/mL with E. cloacae being the most susceptible organism. The study demonstrated the presence of multi-resistant strains of bacteria in ready-to-eat-foods and speculates that these foods could serve as important vehicles transmitting multi-resistant bacteria to humans.
A case study of ozone production, nitrogen oxides, and the radical budget in Mexico City

Abstract. Observations at a mountain-top site within the Mexico City basin are used to characterize ozone production and destruction, nitrogen oxide speciation and chemistry, and the radical budget, with an emphasis on a stagnant air mass observed on one afternoon. The observations compare well with the results of recent photochemical models. An ozone production rate of ~50 ppbv/h was observed in a stagnant air mass during the afternoon of 12 March 2006, which is among the highest observed anywhere in the world. Approximately half of the ozone destruction was due to the oxidation of NO2. During this time period ozone production was VOC-limited, deduced by a comparison of the radical production rates and the formation rate of NOx oxidation products (NOz). For [NOx]/[NOy] values between 0.2 and 0.8, gas-phase HNO3 typically accounted for less than 10% of NOz and accumulation-mode particulate nitrate (NO3(PM1)−) accounted for 20%–70% of NOz, consistent with high ambient NH3 concentrations. The fraction of NOz accounted for by the sum of HNO3(g) and NO3(PM1)− decreased with photochemical processing. This decrease is apparent even when dry deposition of HNO3 is accounted for, and indicates that HNO3 formation decreased relative to other NOx "sink" processes during the first 12 h of photochemistry and/or a significant fraction of the nitrate was associated with the coarse aerosol size mode. The ozone production efficiency of NOx on 11 and 12 March 2006 was approximately 7 on a time scale of one day. A new metric for ozone production efficiency that relates the dilution-adjusted ozone mixing ratio to cumulative OH exposure is proposed.
Echocardiographic abnormalities in dialysis patients with normal ejection fraction.

Disturbances in mineral and bone metabolism in children with chronic kidney disease (CKD) lead to specific abnormalities of skeletal homeostasis called CKD–mineral and bone disorder (CKD-MBD). These disturbances should be diagnosed and managed appropriately to prevent bone deformities and disturbed growth. Changes in the vitamin D and parathyroid hormone (PTH), and the subsequent alterations in calcium (Ca) and phosphate (P) homeostasis are considered responsible for the development of CKD-MBD. Recently, a phosphaturic hormone, the fibroblast growth factor-23 (FGF-23), has been reported as a key regulator of P and vitamin D metabolism. A number of recent studies in paediatric populations have documented that the FGF-23 levels are increased early in CKD, before any abnormalities in serum Ca, P or PTH are apparent. The elevated FGF-23 levels result in a negative P balance to maintain P homeostasis, inducing phosphaturia, independently of PTH, and © The Author 2012.

Prevalence of mental health problems in children and adolescents from the outskirts of Sao Paulo City: treatment needs and service capacity evaluation.

OBJECTIVE To estimate the prevalence of mental health problems in children and adolescents, with or without considering global impairment, within a low-income urban community; to estimate the public service delivery capacity in terms of mental healthcare; and to determine the relationship between delivery capacity and treatment demand. METHOD Cross-sectional study. Probabilistic sample of clusters including all eligible households (low-income community - Embu, Southeastern Brazil). PARTICIPANTS 479 children and adolescents (aged 6-17 years; attrition rate: 18.8%). MEASUREMENT 1) Clinical mental health problems in children and adolescents using the Child Behavior Checklist and/or Youth Self-Report total problem scales; 2) Global impairment: positive score in the Brief Impairment Scale (total score > 15.5); 3) Care service capacity: total number of cases annually seen by psychologists/psychiatrists in the health, education, juvenile justice, and child welfare sectors. RESULTS Prevalence of mental health problems in children and adolescents: 24.6% (20.7-28.5) without considering global impairment; 7.3% (5.0-9.6) with global impairment (cases in need of treatment). Current annual service capacity can only provide care for 14.0% of impaired cases; approximately seven years would be necessary for all to be treated. CONCLUSIONS Mental health problems in children and adolescents are frequent in the studied community, and the current structure of the community's public service system is not prepared to treat impaired cases in an adequate timeframe.
Modeling decision points in user search behavior

Understanding and modeling user behavior is critical to designing search systems: it allows us to drive batch evaluations, predict how users would respond to changes in systems or interfaces, and suggest ideas for improvement. In this work we present a comprehensive model of the interactions between a searcher and a search engine, and the decisions users make in these interactions. The model is designed to deal only with observable phenomena. Based on data from a user study, we are therefore able to make initial estimates of the probabilities associated with various decision points. More sophisticated estimates of these decision points could include probabilities conditioned on some amount of search activity state. In particular, we suggest that one important part of this state is the amount of utility a user is seeking, and how much of this they have collected so far. We propose an experiment to test this, and to elucidate other factors which influence user actions.
A Compact Transmission-Line Self-Matched Negative Group Delay Microwave Circuit

A compact self-matched negative group delay (NGD) circuit without the need for an external matching circuit is proposed. The proposed NGD circuit is composed of two-port open-circuited coupled lines, a short-circuited transmission line and two resistors connected by two transmission lines. The coupled lines are utilized to obtain port matching. To verify the design concept, an NGD circuit with the size of <inline-formula> <tex-math notation="LaTeX">$0.39\lambda _{g}\times 0.19\lambda _{g}$ </tex-math></inline-formula> is designed and fabricated. From the measurement results, NGD value of −8.75 ns at the center frequency of 1.570 GHz is obtained with NGD bandwidth of 3.82%, signal attenuation of less than 20.5 dB and return losses of more than 32 dB.
