Patterns of fixation during face recognition: Differences in autism across age

Difficulties with face recognition increase from adolescence to adulthood in autism, reflecting a lack of typical late development. We examined whether this reflects differences in the development of patterns of fixation to eyes and mouths during face recognition. Children, adolescents, and adults (aged 7–30) with and without autism completed the Cambridge Face Memory Test while gaze was recorded. Average duration and number of fixations were calculated for eyes and mouth regions of interest, defined individually for each face image in the task. All groups and age groups made more and longer fixations to eyes than mouths. However, during face memorization, typically developing children and adults, but not adolescents, made more fixations to eyes than did their peers with autism. During face recognition, typically developing children and adults made shorter fixations on mouths than did their peers with autism; this pattern was reversed in adolescence, with adolescents with autism making more fixations to mouths than typically developing adolescents. Results suggest that group differences in patterns of fixations to faces change with age. Furthermore, different relationships between patterns of fixations and face recognition performance in typical development and autism suggest that these differences contribute, at least in part, to difficulties in autism.
Combined use of T2‐weighted MRI and T1‐weighted dynamic contrast–enhanced MRI in the automated analysis of breast lesions

A multiparametric computer‐aided diagnosis scheme that combines information from T1‐weighted dynamic contrast–enhanced (DCE)‐MRI and T2‐weighted MRI was investigated using a database of 110 malignant and 86 benign breast lesions. Automatic lesion segmentation was performed, and three categories of lesion features (geometric, T1‐weighted DCE, and T2‐weighted) were automatically extracted. Stepwise feature selection was performed considering only geometric features, only T1‐weighted DCE features, only T2‐weighted features, and all features. Features were merged with Bayesian artificial neural networks, and diagnostic performance was evaluated by ROC analysis. With leave‐one‐lesion‐out cross‐validation, an area under the ROC curve value of 0.77 ± 0.03 was achieved with T2‐weighted‐only features, indicating high diagnostic value of information in T2‐weighted images. Area under the ROC curve values of 0.79 ± 0.03 and 0.80 ± 0.03 were obtained for geometric‐only features and T1‐weighted DCE‐only features, respectively. When all features were considered, an area under the ROC curve value of 0.85 ± 0.03 was achieved. We observed P values of 0.006, 0.023, and 0.0014 between the geometric‐only, T1‐weighted DCE‐only, and T2‐weighted‐only features and all features conditions, respectively. When ranked, the P values satisfied the Holm–Bonferroni multiple‐comparison test; thus, the improvement of multiparametric computer‐aided diagnosis was statistically significant. A computer‐aided diagnosis scheme that combines information from T1‐weighted DCE and T2‐weighted MRI may be advantageous over conventional T1‐weighted DCE‐MRI computer‐aided diagnosis.

Free falls from heights: a persistent urban problem.

In order to determine the significance and implications of falls from heights in the North Central Bronx Hospital (NCBH) patient population area, the records of 203 patients who fell from heights of 5 to 72 feet and who died or were admitted to NCBH over a five-year-period were reviewed. Demographic and clinical data were collected and analyzed for 192 of those patients. The findings show a male-to-female ratio of two to one, an age range of four months to 86 years, and a disproportionately high incidence of falls among minority group children.Seventy-six percent of patients had skeletal, 12 percent abdominal, and 10 percent skull fractures and cerebral edema. Twenty-two percent of juveniles (0 to 17 years) and 5 percent of adults had craniocerebral trauma. Thirty-one percent required surgery. Ten percent of the admitted patients had permanent disabilities. A trauma scoring system, the Injury Severity Score, correlated directly with height fallen. Overall mortality was 28 percent but only 6.6 percent in the juvenile group. Most of the falls were accidental (45 percent) or suicide attempts (22 percent). Although recognized as a health problem at least since 1965, falls from heights continue to be a cause of morbidity and mortality in urban people 20 years later. Renewed efforts at education and the passage and enforcement of public health laws are needed if their numbers are to be decreased.
Effect of cation–anion balance in feed on urine pH in rabbits in comparison with other species

In the present investigation, the impact of diet composition on urine pH in rabbits was compared with previous studies on rabbits, cats, dogs, pigs and horses. A total of 13 dwarf rabbits were fed six different diets with a cation-anion balance (CAB) between -39 and +320 mmol/kg dry matter (DM) using ammonium chloride (NH4 Cl) as an acidifier. CAB was calculated as follows: CAB (mmol/kg DM) = 49.9*Ca + 82.3*Mg +43.5*Na + 25.6*K - 59*P - 62.4*S - 28.2*Cl; minerals in g/kg DM. Urine, faeces and blood were collected. Urine pH ranged from 5.26 ± 0.22 at a CAB of -39 mmol/kg DM to 8.56 ± 0.24 at a CAB of +320 mmol/kg DM. A low CAB in the feed reduced blood pH and blood base excess significantly. Renal excretion of Ca, P, Na and Mg and water was significantly higher in rabbits eating acidifying diets. In comparison with other species, rabbits reacted to acidifying diets in a similar way as cats, dogs and pigs. Rabbits on a mildly alkalizing diet, however, had a trend to higher urine pH than other monogastric species on such diets (cats, dogs, pigs, horses).
Monitoring and surveillance for multiple micronutrient supplements in pregnancy

Abstract The World Health Organization (WHO) recommends iron–folic acid (IFA) supplementation during pregnancy to improve maternal and infant health outcomes. Multiple micronutrient (MMN) supplementation in pregnancy has been implemented in select countries and emerging evidence suggests that MMN supplementation in pregnancy may provide additional benefits compared to IFA alone. In 2015, WHO, the United Nations Children's Fund (UNICEF), and the Micronutrient Initiative held a “Technical Consultation on MMN supplements in pregnancy: implementation considerations for successful incorporation into existing programmemes,” which included a call for indicators needed for monitoring, evaluation, and surveillance of MMN supplementation programmes. Currently, global surveillance and monitoring data show that overall IFA supplementation programmes suffer from low coverage and intake adherence, despite inclusion in national policies. Common barriers that limit the effectiveness of IFA—which also apply to MMN programmes—include weak supply chains, low access to antenatal care services, low‐quality behaviour change interventions to support and motivate women, and weak or non‐existent monitoring systems used for programme improvement. The causes of these barriers in a given country need careful review to resolve them. As countries heighten their focus on supplementation during pregnancy, or if they decide to initiate or transition into MMN supplementation, a priority is to identify key monitoring indicators to address these issues and support effective programmes. National and global monitoring and surveillance data on IFA supplementation during pregnancy are primarily derived from cross‐sectional surveys and, on a more routine basis, through health and logistics management information systems. Indicators for IFA supplementation exist; however, the new indicators for MMN supplementation need to be incorporated. We reviewed practice‐based evidence, guided by the WHO/Centers for Disease Control and Prevention logic model for vitamin and mineral interventions in public health programmes, and used existing manuals, published literature, country reports, and the opinion of experts, to identify monitoring, evaluation, and surveillance indicators for MMN supplementation programmes. We also considered cross‐cutting indicators that could be used across programme settings, as well as those specific to common delivery models, such as antenatal care services. We then described mechanisms for collecting these data, including integration within existing government monitoring systems, as well as other existing or proposed systems. Monitoring data needs at all stages of the programme lifecycle were considered, as well as the feasibility and cost of data collection. We also propose revisions to global‐, national‐, and subnational‐surveillance indicators based on these reviews.
Changes in the hemagglutinins and neuraminidases of human influenza B viruses isolated in Italy during the 2001–02, 2002–03, and 2003–04 seasons

Throughout most of the last decade, B/Yamagata/16/88‐lineage influenza viruses were predominant among the B isolates circulating worldwide, whereas B/Victoria/2/87‐lineage viruses were isolated infrequently and restricted geographically to eastern Asia. During the 2001–02 influenza season, B/Victoria/2/87‐lineage viruses re‐emerged in North America and Europe and spread worldwide. Virological surveillance in Italy during that season showed wide circulation of influenza B viruses, of which most were antigenically related to the B/Sichuan/379/99 (Yamagata‐lineage) vaccine strain, together with a smaller number of B viruses antigenically similar to B/HongKong/330/01, a recent B/Victoria/2/87‐lineage antigenic variant. In the subsequent 2002–03 epidemic season, B viruses with a Victoria‐lineage hemagglutinin (HA), more closely related to that of B/Shandong/7/97, were isolated exclusively. Similar strains have continued to predominate among the few B viruses isolated in Italy during last season (2003–04), although most influenza B viruses, isolated sporadically elsewhere in Europe, again belong to the Yamagata‐lineage. In the present study, phylogenetic analyses of the HA and neuraminidase (NA) genes of representative B strains, isolated throughout Italy during 2001–04, showed that during the first influenza season the NA genes, as well as the HA genes, separated into the two distinct clades, the Yamagata‐ and Victoria‐lineages, and showed no evidence of genetic reassortment. On the contrary, all the B viruses isolated in the 2002–03 and most of those isolated in the 2003–04 epidemic season were “Victoria HA–Yamagata NA” reassortants similar to those isolated in other parts of the world, showing that these reassortants became established in the human population. The frequency of reassortment between HA and NA of distinct lineages and sublineages highlights again the importance of detailed molecular analyses of both surface glycoproteins in understanding the evolution of influenza B viruses.

Essays on robust portfolio selection and pension finance

This thesis examines three different, but related problems in the broad area of portfolio management for long-term institutional investors, and focuses mainly on the case of pension funds. The first idea (Chapter 3) is the application of a novel numerical technique – robust optimization – to a real-world pension scheme (the Universities Superannuation Scheme, USS) for first time. The corresponding empirical results are supported by many robustness checks and several benchmarks such as the Bayes-Stein and Black-Litterman models that are also applied for first time in a pension ALM framework, the Sharpe and Tint model and the actual USS asset allocations. The second idea presented in Chapter 4 is the investigation of whether the selection of the portfolio construction strategy matters in the SRI industry, an issue of great importance for long term investors. This study applies a variety of optimal and naive portfolio diversification techniques to the same SRI-screened universe, and gives some answers to the question of which portfolio strategies tend to create superior SRI portfolios. Finally, the third idea (Chapter 5) compares the performance of a real-world pension scheme (USS) before and after the recent major changes in the pension rules under different dynamic asset allocation strategies and the fixed-mix portfolio approach and quantifies the redistributive effects between various stakeholders. Although this study deals with a specific pension scheme, the methodology can be applied by other major pension schemes in countries such as the UK and USA that have changed their rules.
Reporting and use of the OECD Health Care Quality Indicators at national and regional level in 15 countries.

QUALITY PROBLEM OR ISSUE OECD member states are involved since 2003 in a project coordinated by the OECD on Health Care Quality Indicators (HCQI). All OECD countries are biennially requested by the OECD to deliver national data on the quality indicators for international benchmarking purposes. INITIAL ASSESSMENT Currently, there is no knowledge whether the OECD HCQI information is used by the countries themselves for healthcare system accountability and improvement purposes. CHOICE OF SOLUTION The objective of the study is to explore the reporting and use of OECD HCQI in OECD member-states. IMPLEMENTATION Data were collected through a questionnaire sent to all OECD member-states containing factual questions on the reporting on all OECD HCQ-indicators. Responses were received between June and December 2014. In this timeframe, two reminders were sent to the participants. The work progress was presented during HCQI Meetings in November 2014 and May 2015. EVALUATION Fifteen countries reported to have a total of 163 reports in which one or more HCQIs were reported. One hundred and sixteen were national and 47 were regional reports. Forty-nine reports had a general system focus, 80 were disease specific, 10 referred to a specific type of care setting, 22 were thematic and 2 were a combination of two (disease specific for a particular type of care and thematic for a specific type of care). Most reports were from Canada: 49. All 15 countries use one or more OECD indicators. LESSONS LEARNED The OECD quality indicators have acquired a clear place in national and regional monitoring activities. Some indicators are reported more often than others. These differences partly reflect differences between healthcare systems. Whereas some indicators have become very common, such as cancer care indicators, others, such as mental healthcare and patient experience indicators are relatively new and require some more time to be adopted more widely.
Association of the Tim14·Tim16 Subcomplex with the TIM23 Translocase Is Crucial for Function of the Mitochondrial Protein Import Motor*

Tim14 and Tim16 are essential components of the import motor of the mitochondrial TIM23 preprotein translocase. Tim14 contains a J domain in the matrix space that is anchored in the inner membrane by a transmembrane segment. Tim16 is a J-related protein with a moderately hydrophobic segment at its N terminus. The J and J-like domains function in the regulation of the ATPase activity of the Hsp70 chaperone of the import motor. We report here on the role of the hydrophobic segments of Tim16 and Tim14 in the TIM23 translocase. Yeast cells lacking the hydrophobic N-terminal segment in either Tim16 or Tim14 are viable but show growth defects and decreased import rates of matrix-targeted preproteins into mitochondria. The interaction of the Tim14·Tim16 complex with the core complex of the TIM23 translocase is destabilized in these cells. In particular, the N-terminal domain of Tim16 is crucial for the interaction of the Tim14·Tim16 complex with the TIM23 preprotein translocase. Deletion of hydrophobic segments in both, Tim16 and Tim14, is lethal. We conclude that import into the matrix space of mitochondria requires association of the co-chaperones Tim16 and Tim14 with the TIM23 preprotein translocase.
Non-Public Shareholders’ Ownership and Economic Performance in the Urban Public-Transport Companies. Empirical Evidence from European Union

Urban mobility (UM) represents an increasingly important field in European Union policy agenda. The growing complexity of citizens’ needs and the criticalities related to the global economic downturn have reduced the amount of the public expenditure that can be invested to cover the UM systems’ requirements. From this perspective, private funding is unavoidable. Public-private partnerships are more and more widespread. In particular, we look to a more relevant non-public shareholders’ presence in the ownership structure of urban public-transport companies. Many scholars have investigated the relationship between the presence of non-public shareholders and the economic performance generated by these companies. Nevertheless, less attention is paid to the “intensity” of non-public shareholders’ presence on firm performance. Moreover, cross-country comparisons are infrequently explored. In light of these considerations, this paper aims to test whether a lesser or higher presence (i.e. the intensity) of non-public shareholders in the ownership structure of the urban public-transport companies can affect economic performance. This research issue is investigated by statistical methodologies focusing on a sample made up by 333 companies operating in 12 European Union countries. Findings, managerial implications and suggestions for future research are outlined and discussed.
Pilot Study of the Genetic Diversity of the Pneumococcal Nasopharyngeal Flora among Children Attending Day Care Centers

ABSTRACT A pilot study was conducted to determine the genetic diversity of multiple colonies of pneumococci recovered from 37 nasopharyngeal (NP) samples of children. A total of 239 pneumococcal isolates (typically, six to eight colonies per sample) were typed by pulsed-field gel electrophoresis (PFGE). In most NP samples (89%) the multiple colonies shared common PFGE types and serotypes. However, four samples were heterogeneous (samples A through D): each contained two strains with different PFGE types, antibiotypes, and serotypes. Samples A and B each contained one strain of a vaccine capsular type and another expressing a non-vaccine type (according to the currently licensed seven-valent conjugate vaccine). In samples B and C the penicillin MIC for one strain was elevated and the other strain was susceptible. In each of the heterogeneous samples, one of the strains was a representative of an internationally disseminated clone. Samples A, C, and D contained strains which carried prophages that were inducible by mitomycin C and that could be visualized by electron microscopy. The comC gene allele (which encodes the competence-stimulating peptide) was the same in both strains found in each of samples A, B, and D. Carriage of multiple pneumococci with distinct properties should favor genetic exchange and provide a dynamic population structure for pneumococci in their ecological reservoir. Quantitative resolution of majority and minority components of the pneumococcal NP flora will be of importance for evaluation of the impact of intervention strategies such as vaccination or introduction of new antimicrobial agents.
Evaluation of surface radiation dose to the thyroid gland and the gonads during routine full-mouth intraoral periapical and maxillary occlusal radiography

Aim: The quantitative aspects of radiation doses to critical organs can help the dental professionals to take the necessary radiation protective measures as deemed necessary and can help the general public to allay radiation exposure fear in dental radiography, if any. Our study determines the surface radiation dose to thyroid and gonads in full-mouth intraoral periapical (IOPA) and maxillary occlusal radiography. Materials and Methods: A total number of 120 subjects participated in the study. The surface radiation dose was estimated to the thyroid gland and the gonads in full-mouth IOPA radiography using 10 IOPA (E speed films) and in maxillary occlusal radiography. The measurements were calculated using a digital pocket dosimeter (PD-4507). Results: The average dose at the thyroid gland level during full-mouth intraoral and maxillary occlusal radiography was estimated to be 10.93 mRads (1.093 × 10-2 mGy) and 0.4 mRads (4.0 × 10-2 mGy), respectively. The average surface radiation dose at the gonadal region during a full mouth intraoral and maxillary occlusal radiography was estimated to be 1.5 mRads (1.5 × 10-2 mGy) and 0.15 mRads (1.5 × 10-3 mGy), respectively. Conclusion: Our results suggest that although the radiation exposure doses to critical organs namely thyroid and gonads is within the safe limits still precautionary measures for these organs are advocated.
Adenovirus type 4 respiratory infections with a concurrent outbreak of coxsackievirus A21 among United States Army Basic Trainees, a retrospective viral etiology study using next‐generation sequencing

Human adenoviruses (HAdV), in particular types 4 and 7, frequently cause acute respiratory disease (ARD) during basic military training. HAdV4 and HAdV7 vaccines reduced the ARD risk in U.S. military. It is important to identify other respiratory pathogens and assess their potential impact on military readiness. In 2002, during a period when the HAdV vaccines were not available, throat swabs were taken from trainees (n = 184) with respiratory infections at Fort Jackson, South Carolina. Viral etiology was investigated initially with viral culture and neutralization assay and recently in this study by sequencing the viral isolates. Viral culture and neutralization assays identified 90 HAdV4 isolates and 27 additional cultures that showed viral cytopathic effects (CPE), including some with picornavirus‐like CPE. Next‐generation sequencing confirmed these results and determined viral genotypes, including 77 HAdV4, 4 HAdV3, 1 HAdV2, 17 coxsackievirus A21 (CAV21), and 1 enterovirus D68. Two samples were positive for both HAdV4 and CAV21. The identified genotypes are phylogenetically close to but distinct from those found during other years or in other military/non‐military sites. HAdV4 is the predominant respiratory pathogen in unvaccinated military trainee. HAdV4 has temporal and demographic variability. CAV21 is a significant respiratory pathogen and needs to be evaluated for its current significance in military basic trainees.
