Correlates of self-reported help-seeking among adolescents

The present study examined demographic and psychological correlates of helpseeking behavior in a sample of 220 (111 males, 109 females) adolescents, ranging in age from 12 to 19 years (mean age = 15.0 years). Adolescents were administered measures of self-worth, self-consciousness, and locus of control. Adolescents were also asked to report whether or not they had sought help from their mothers, fathers, friends, and professionals for assistance with emotional problems during the past year. Results revealed that, overall, females sought more help than males from mothers, friends, and professionals. Older adolescents sought more help than younger adolescents from friends and professionals. A series of discriminant function analyses were conducted in order to determine the extent to which each of the demographic and psychological variables significantly discriminated between those adolescents who sought help (help-seekers) and those adolescents who did not (nonseekers). Reliable differences were found to significantly discriminate between the demographic and psychological predictors of seeking help for each helping resource. Self-worth was found to be significant in predicting seeking help from friends and professionals. Self-consciousness was found to significantly predict seeking help from father, friends, and professionals. Additionally, locus of control was a significant predictor of seeking help from mother, father and friends. The findings are discussed in terms of their implications for mental health intervention during adolescence.
Wavelength-Dependent Degradation of Ochratoxin and Citrinin by Light in Vitro and in Vivo and Its Implications on Penicillium

It has previously been shown that the biosynthesis of the mycotoxins ochratoxin A and B and of citrinin by Penicillium is regulated by light. However, not only the biosynthesis of these mycotoxins, but also the molecules themselves are strongly affected by light of certain wavelengths. The white light and blue light of 470 and 455 nm are especially able to degrade ochratoxin A, ochratoxin B and citrinin after exposure for a certain time. After the same treatment of the secondary metabolites with red (627 nm), yellow (590 nm) or green (530 nm) light or in the dark, almost no degradation occurred during that time indicating the blue light as the responsible part of the spectrum. The two derivatives of ochratoxin (A and B) are degraded to certain definitive degradation products which were characterized by HPLC-FLD-FTMS. The degradation products of ochratoxin A and B did no longer contain phenylalanine however were still chlorinated in the case of ochratoxin A. Citrinin is completely degraded by blue light. A fluorescent band was no longer visible after detection by TLC suggesting a higher sensitivity and apparently greater absorbance of energy by citrinin. The fact that especially blue light degrades the three secondary metabolites is apparently attributed to the absorption spectra of the metabolites which all have an optimum in the short wave length range. The absorption range of citrinin is, in particular, broader and includes the wave length of blue light. In wheat, which was contaminated with an ochratoxin A producing culture of Penicillium verrucosum and treated with blue light after a pre-incubation by the fungus, the concentration of the preformed ochratoxin A reduced by roughly 50% compared to the control and differed by > 90% compared to the sample incubated further in the dark. This indicates that the light degrading effect is also exerted in vivo, e.g., on food surfaces. The biological consequences of the light instability of the toxins are discussed.
Interest and Interests: The Psychology of Constructive Capriciousness

This article develops a perspective on interest and interests as aspects of motivation, emotion, and personality. Interest is viewed as a capricious emotion with few, if any, immediate adaptational functions; it serves long-term adaptational goals by cultivating knowledge and diversifying skills and experience. Interests are viewed as idiosyncratic intrinsic motives that promote expertise. Theories of how interests arise are reviewed and organized. A model of how the emotion of interest participates in the development of enduring interests is proposed. The author concludes that apparently frivolous aspects of motivation and personality such as “idle curiosity” and avocations seem to play complex roles in human experience and development.
Creating Organizational Capability in New Businesses : Building Sets of Complementary Capabilities

Recent research into the development of organizational capability, has focused either upon particular aspects of the development process (e.g. learning, routinization, heuristics, bricolage) or on individual capabilities (e.g. new product development, project management, internationalization, acquisitions). Limited attention has been given to how firms create new systems of capabilities despite the fact that commercial viability requires firms to master multiple, complementary capabilities. Recent emphasis on the firm as a configuration of interdependent, complementary activities reinforces the view that the central management challenge for launching successful new business ventures is building an integrated system of capabilities. Through in-depth studies of four new e-commerce businesses, we tracked the creation and development of new systems of organizational capabilities, identifying commonalities in this process despite differences in firm type and sector. Our findings augment the existing literature by offering deeper and more detailed insight into the main components of the capability development. We identified a management-led process of capability building in which initial strategic intent was translated into capability architecture—an envisaging of the required functionality of the business both at systemic and component levels. Operationalizing capability architecture required the sourcing of relevant knowledge, the translation of capability architecture into organizational structure, and the establishment and development of organizational processes through patterns of routinization and codification.

Degeneration of Kähler-Einstein Manifolds II: the Toroidal case

In this paper we prove that the K\"{a}hler-Einstein metrics for a toroidal canonical degeneration family of K\"{a}hler manifolds with ample canonical bundles Gromov-Hausdorff converge to the complete K\"{a}hler-Einstein metric on the smooth part of the central fiber when the base locus of the degeneration family is empty. We also prove the incompleteness of the Weil-Peterson metric in this case.
Lymphangiogenesis and biological behavior in pancreatic carcinoma and other pancreatic tumors

Lymphatic vessels in primary tumor tissue play an important role in lymphatic metastasis. Lymphatic metastasis of malignant neoplasms is significantly related to prognosis, influencing both recurrence and survival. The aim of this study was to investigate the correlation of intra-tumoral lymphatic vessel density (iLVD) and peri-tumoral lymphatic vessel density (pLVD) with biological behavior and prognostic parameters in pancreatic carcinoma (PC) and other pancreatic tumors. Lymphangiogenesis was examined using the D2-40 monoclonal antibody in 33 cases of PC, 7 neuroendocrine tumors of the pancreas (NETP), 7 solid pseudopapillary tumors of the pancreas (SPTP) and 3 cystadenomas of the pancreas (CP). Positively-stained microvessels were counted at magnification ×400 in dense lymphatic vascular foci (hotspots). The LVD of PC was compared to 3 other pancreatic tumors. The relationships among the LVD, the extent of differentiation, lymphatic invasion, lymph node metastasis and other clinicopathological parameters of PC were analyzed. There was no difference in the iLVD among PC, NETP, SPTP and CP. The pLVD of NETP was markedly higher than that of PC, SPTP and CP. The pLVD of PC was significantly higher than that of SPTP and CP, but there was no difference between SPTP and CP. The pLVD of PC was significantly associated with the extent of differentiation, lymphatic invasion and lymph node metastasis, whereas it was not associated with age, gender, tumor size, tumor location and peri-pancreatic invasion. The iLVD of PC was not correlated with these clinicopathological parameters. There was no difference in iLVD and no marked difference in pLVD among the pancreatic tumors. Detection of pLVD is of greater importance than detecting iLVD in these pancreatic tumors, as pLVD can be utilized for the prediction of lymph node metastasis, thus aiding in the evaluation of patient prognosis.
Can We Find Common Rules of Browsing Behavior

This paper describes our efforts to investigate factors in user’s browsing behavior to automatically evaluate web pages that the user shows interest in. To evaluate web pages automatically, we developed a client-side logging/analyzing tool: the GINIS Framework. We do not focus on just clicking, scrolling, navigation, or duration of visit alone, but we propose integrating these patterns of interaction to recognize and evaluate user response to a given web page. Unlike most previous web studies that have analyzed access seen at proxies or server, this work focuses primarily on client-side user behavior using a customized web browser. First, GINIS unobtrusively gathers logs of user behavior through the user’s natural interaction with the web browser. Then it analyses the logs and extracts effective rules to evaluate web pages using C4.5 machine learning system. Eventually, GINIS becomes able to automatically evaluate web pages using these learned rules, after which the evaluation can be utilized for a variety of user profiling applications. We successfully confirmed, for example, that time spent on a web page is not the most important factor in predicting interest from behavior, which conflict with the finding of most previous studies.
Power aware test-data compression for scan-based testing

In this paper a new approach that targets the reduction of both the test-data volume and the scan-power dissipation during testing of a digital system's cores is proposed. For achieving the two aforementioned goals, a novel algorithm that inserts some inverters in the scan chain(s) of the core under test (CUT) is presented. However, no performance or area penalty is imposed on the CUT since, instead of additional inverters, the negated outputs of the scan flip-flops can be utilized. The proposed algorithm targets the maximization of run-lengths of zeros (or ones) in the test set accompanying the CUT. This algorithm combined with the Minimum Transition Count mapping of don't cares in a test set as well as with the alternating run-length code that have been recently proposed, achieves better test-data compression and reduced scan-power results than the relative works in the literature.
School-Based Health Center Intervention Improves Body Mass Index in Overweight and Obese Adolescents

Adolescents Committed to Improvement of Nutrition and Physical Activity (ACTION) was undertaken to determine feasibility of a school-based health center (SBHC) weight management program. Two urban New Mexico SBHCs were randomized to deliver ACTION or standard care. ACTION consisted of eight visits using motivational interviewing to improve eating and physical activity behavior. An educational nutrition and physical activity DVD for students and a clinician toolkit were created for use as menu of options. Standard care consisted of one visit with the SBHC provider who prescribed recommendations for healthy weight. Sixty nondiabetic overweight/obese adolescents were enrolled. Measures included BMI percentile, waist circumference, insulin resistance by homeostasis model assessment (HOMA-IR), blood pressure, triglycerides, and HDL-C levels. Pre- to postchanges for participants were compared between groups. Fifty-one students (mean age 15 years, 62% female, 75% Hispanic) completed pre- and postmeasures. ACTION students (n = 28) had improvements in BMI percentile (P = 0.04) and waist circumference (P = 0.04) as compared with students receiving standard care (n = 23). No differences were found between the two groups in blood pressure, HOMA-IR, triglycerides, and HDL-C. The ACTION SBHC weight management program was feasible and demonstrated improved outcomes in BMI percentile and waist circumference.

This paper provides a summary and synthesis and of the reviewed literature and concludes by discussing possible significance for higher education and directions for future research.
Orthorectification and Geometric Quality Assessment of Cartosat-1 For Common Agricultural Policy Monitoring: Final Results

The European Union uses remotely sensed data in a large operational programme to monitor subsidies given to farmers and to identify irregularities in claims. The trend over the last few years has been in sharp increase in the use of very high resolution sensors, with a number of different sensors being used in a complementary manner. For instance, whilst instruments able to provide imagery with a ground sampling distance (GSD) of <1m make up the primary use (with acquisition in 2006 of around 150,000 km2), sensors acquiring data with around a 2m GSD are in general used as a back-up in case of primary instrument acquisition failure. Cartosat-1 test data, which falls into this 2nd category and potentially could provide useful data in the main programme, was imaged in the framework of the Cartosat-1 Scientific Assessment Programme (C-SAP). This paper presents the final results of sensor model and DEM extraction for Cartosat -1 full dataset (two stereo pairs) for a test site located near to Mausanne-les-Alpilles (France), used since 1997 with a time series of reference data for the checking of farmers’ aid applications. The chosen approach was to: First, determine the best method for image rectification and model adjustment; this was verified by undertaking a series of orthorectifications and comparing results with independent check points. Off-the-shelf software (PCI Geomatica 10 and LPS) was used for the evaluation. Second, upon selecting the chosen model creation approach, undertake the extraction of the DEM using the stereo pairs, and proceed with the DEM quality assessment. Moreover, for the assessment of the DEM generation purpose fully automated models were prepared based on GIS techniques. In brief, the full DEM covering the study site is compared with a reference DEM (of higher quality), and assessed according to the land cover and slope categories thus enabling application specific assessment of the DEM generation and potential for image use. Lastly, the quality assessment of SRTM (open source) for the same AOI was prepared and compared with obtained results form Cartosat – 1 DEM extraction process evaluation.
Hybrid Hexagonal/Classical Tiling for GPUs

Time-tiling is necessary for the efficient execution of iterative stencil computations. Classical hyper-rectangular tiles cannot be used due to the combination of backward and forward dependences along space dimensions. Existing techniques trade temporal data reuse for inefficiencies in other areas, such as load imbalance, redundant computations, or increased control flow overhead, therefore making it challenging for use with GPUs. We propose a time-tiling method for iterative stencil computations on GPUs. Our method does not involve redundant computations. It favors coalesced global-memory accesses, data reuse in local/shared-memory or cache, avoidance of thread divergence, and concurrency, combining hexagonal tile shapes along the time and one spatial dimension with classical tiling along the other spatial dimensions. Hexagonal tiles expose multi-level parallelism as well as data reuse. Experimental results demonstrate significant performance improvements over existing stencil compilers.
The Scavenger Receptor SSc5D Physically Interacts with Bacteria through the SRCR-Containing N-Terminal Domain

The scavenger receptor cysteine-rich (SRCR) family comprises a group of membrane-attached or secreted proteins that contain one or more modules/domains structurally similar to the membrane distal domain of type I macrophage scavenger receptor. Although no all-inclusive biological function has been ascribed to the SRCR family, some of these receptors have been shown to recognize pathogen-associated molecular patterns (PAMP) of bacteria, fungi, or other microbes. SSc5D is a recently described soluble SRCR receptor produced by monocytes/macrophages and T lymphocytes, consisting of an N-terminal portion, which contains five SRCR modules, and a large C-terminal mucin-like domain. Toward establishing a global common role for SRCR domains, we interrogated whether the set of five SRCR domains of SSc5D displayed pattern recognition receptor (PRR) properties. For that purpose, we have expressed in a mammalian expression system the N-terminal SRCR-containing moiety of SSc5D (N-SSc5D), thus excluding the mucin-like domain likely by nature to bind microorganisms, and tested the capacity of the SRCR functional groups to physically interact with bacteria. Using conventional protein–bacteria binding assays, we showed that N-SSc5D had a superior capacity to bind to Escherichia coli strains RS218 and IHE3034 compared with that of the extracellular domains of the SRCR proteins CD5 and CD6 (sCD5 and sCD6, respectively), and similar E. coli-binding properties as Spα, a proven PRR of the SRCR family. We have further designed a more sensitive, real-time, and label-free surface plasmon resonance (SPR)-based assay and examined the capacity of N-SSc5D, Spα, sCD5, and sCD6 to bind to different bacteria. We demonstrated that N-SSc5D compares with Spα in the capacity to bind to E. coli and Listeria monocytogenes, and further that it can distinguish between pathogenic E. coli RS218 and IHE3034 strains and the non-pathogenic laboratory E. coli strain BL21(DE3). Our work thus advocates the utility of SPR-based assays as sensitive tools for the rapid screening of interactions between immune-related receptors and PAMP-bearing microbes. The analysis of our results suggests that SRCR domains of different members of the family have a differential capacity to interact with bacteria, and further that the same receptor can discriminate between different bacteria strains and species.
Star formation history up to z = 7.4: implications for gamma-ray bursts and cosmic metallicity evolution

The current Swift sample of gamma-ray bursts (GRBs) with measured redshifts allows us to test the assumption that GRBs trace star formation in the Universe. Some authors have claimed that the rate of GRBs increases with cosmic redshift faster than the star formation rate, whose cause is not yet known. In this paper, I investigate the possibility of interpreting the observed discrepancy between the GRB rate history and the star formation rate history using cosmic metallicity evolution. I am motivated by the observation that cosmic metallicity evolves with redshift and GRBs tend to occur in low-metallicity galaxies. First, I derive a star formation history up to redshift z = 7.4 from an updated sample of star formation rate densities. This is obtained by adding the new ultraviolet measurements of Bouwens et al. and the new ultraviolet and infrared measurements of Reddy et al. to the existing sample compiled by Hopkins & Beacom. Then, adopting a simple model for the relation between GRB production and the cosmic metallicity history as proposed by Langer & Norman, I show that the observed redshift distribution of the Swift GRBs can be reproduced with good accuracy. Although the results are limited by the small size of the GRB sample and the poorly understood selection biases in detection and localization of GRBs and in redshift determination, they suggest that GRBs trace both star formation and metallicity evolution. If the star formation history can be accurately measured with other approaches, which is presumably achievable in the near future, it will be possible to determine the cosmic metallicity evolution using the study of the redshift distribution of GRBs.
Chemo-spectrophotometric evolution of spiral galaxies — III. Abundance and colour gradients in discs

We study the relations between luminosity and chemical-abundance profiles of spiral galaxies, using detailed models for the chemical and spectrophotometric evolution of galactic discs. The models are ‘calibrated’ on the Milky Way disc and are successfully extended to other discs with the help of simple ‘scaling’ relations, obtained in the framework of semi-analytic models of galaxy formation. We find that our models exhibit oxygen abundance gradients that increase in absolute value with decreasing disc luminosity (when expressed in dex kpc−1) and are independent of disc luminosity (when expressed in dex scalelength−1), both in agreement with observations. We notice an important strong correlation between abundance gradient and disc scalelength. These results support the idea of ‘homologous evolution’ of galactic discs.
The Digital Divide as a Complex and Dynamic Phenomenon

The purpose of this article is to propose a fruitful analytical framework for data supposedly related to the concept of the so-called "digital divide. " The extent and the nature of this divide depend on the kind of access defined. Considering the possession of hardware, growing divides among different categories of income, employment, education, age, and ethnicity can be proved to have existed in the 1980s and 1990s according to official American and Dutch statistics. If only by effects of saturation, these gaps will more or less close. However, it is shown that differential access of skills and usage is likely to increase. The growth of a usage gap is projected. Multivariate analyses of Dutch official statistics reveal the striking effect of age and gender as compared to education. The usage gap is related to the evolution of the information and network society. Finally, policy perspectives are discussed.
The Simultaneous Conjugacy Problem in Thompson's Group $F$

Guba and Sapir asked, in their joint paper [3], if the simultaneous conjugacy problem was solvable in Diagram Groups or, at least, for Thompson's group F. We give an elementary proof for the solution of the latter question. This relies purely on the description of F as the group of piecewise linear orientation-preserving homeomorphisms of the unit interval with dyadic break-points and slopes that are powers of 2. We show that, with the techniques we develop, we can solve the ordinary conjugacy problem as well, and we can compute roots and centralizers. Moreover, these techniques can be generalized to solve the same questions in larger groups of piecewise-linear homeomorphisms.
