The Influence of Self-Efficacy Towards the Grit of Multidisciplinary Post-graduate Students

The main purpose of this research was to know the effect of self-efficacy towards the multidisciplinary post-graduate students’ grit. A grit is an encouragement that comes from within the individual in the form of persistence to attract and maintain the spirit to keep struggling in order to face the challenge for the achieving the goal. Students who have higher grit will more easily pass the obstacles in college. The sampling technique used in this study was on-probability sampling with incidental sampling technique. Incidental sampling technique was carried out with the consideration that the characteristics of the subject were difficult to find. The population in this study involved 38 multidisciplinary post-graduate students at fourth semester in graduate program of one university in Surabaya. The conclusion of this research was that self-efficacy has influence to the grit with medium category. One way to achieve success in college is by becoming a gritty student. A gritty student can be achieved by firstly increasing self-efficacy of the post-graduate students. Keyword-Grit, multidisciplinary, postgraduate, self-efficacy
The Risk of Trust in Safety: Confidence Games

This paper investigates the relationship between confidence, trust and risk. It proposes a game theoretical representation of confidence (trust). Confidence games explain to some extent similarities (differences) between confidence and trust. Moreover, the link between confidence and trust, in terms of games, allows a characterization of risk with respect to confidence.
An empirical test of the Olympic tourism legacy

ABSTRACT International tourism legacies are a key justification for hosting the Olympics. Although strong theoretical arguments have been made to support the tourism legacy, empirically measuring the effect has been problematic. Strong arguments for enhancing the legacy effect through the proper leveraging of the Olympics by means such as positive media coverage exist. This research empirically tests for the legacy effect and whether leveraging the Olympics by exposing potential tourists to more media enhances the legacy effect. The data used in this research are monthly international air passenger arrivals for nine Olympic host cities. A time series methodology that controls for problems noted in prior studies such as pre-existing trends, external events, seasonality, and crowding out is incorporated. The results show little evidence to support the legacy effect in the short run.
The Interleaved Multichromatic Number of a

For k 1, we consider interleaved k-tuple colorings of the nodes of a graph, that is, the assignment of k distinct natural numbers to each node in such a way that nodes that are connected by an edge receive numbers that are strictly alternating between them with respect to the relation <. If it takes at least k int (G) distinct numbers to provide graph G with such a coloring, then the interleaved multichromatic number of G is int (G) = inf k1 k int (G)=k and is known to be given by a function of the simple cycles of G under acyclic orientations if G is connected. This paper contains a new proof of this result. Unlike the original proof, the new proof makes no assumptions on the connectedness of G, nor does it resort to the possible applications of interleaved k-tuple colorings and their properties.
Performance and governance of Swiss pension funds

Abstract We investigate the relationship between pension fund governance and investment performance. For this purpose, we develop the Swiss Pension Fund Governance Index (SPGI) which is a standard metric for the governance quality of Swiss pension funds. The empirical analysis is based on a sample of 96 pension funds with total assets of more than CHF 190 billion. We find evidence for governance issues in the area organization and target setting. Our results support the widespread hypothesis of a positive relationship between pension fund governance and investment performance.
Prevalence of Zoonotic Trematodes in Fish from a Vietnamese Fish-Farming Community

The prevalence of fish-borne zoonotic trematode (FZT) metacercariae was investigated in fish farmed by rural households in Nghe An Province, located in northern Vietnam. In total, 716 fish, including tilapia (Oreochromis niloticus) and 6 carp species, i.e., grass carp (Ctenopharyngodon idellus), bighead carp (Aristichthys nobilis), mrigal (Cirrhinus mrigala), common carp (Cyprinus carpio), silver carp (Hypophthalmychthys molitrix), and roha (Labeo rohita), collected from 53 fish farms were examined. The overall prevalence of FZT metacercariae was 44.6%, ranging from 12.5% to 61.0% in fish species collected from grow-out ponds, which are the production system for growing fish from fingerling size to market size. The overall prevalence was 43.6% in fingerlings cultured in nurseries, ranging from 7.4% to 62.8% for different fish species. The FZT species recovered were heterophyids and echinostomatids and included Haplorchis pumilio, H. taichui, H. yokogawai, Centrocestus formosanus, Stellantchasmus falcatus, and Echinochasmus japonicus, all of which are intestinal flukes in humans, other mammals, and birds. This is the first report of H. yokogawai and E. japonicus in fish in Vietnam, and the first record for S. falcatus in northern Vietnam. Although a previous cross-sectional survey of the people living in these fish farm households revealed a very low prevalence of FZTs (<1%), our results demonstrate that intestinal flukes are common in farmed fish in this area, suggesting that reservoir hosts such as dogs, cats, and pigs are more important in sustaining the life cycles of these flukes in fish farms than human hosts. This has implications for the effectiveness of control programs focused mainly on treatment of humans.
Valence band anticrossing in mismatched III-V semiconductor alloys

The valence band anticrossing model (VBAC) is applied to explain the composition-dependent trends in dilute GaSbxAs1–x and GaBixAs1–x alloys. Photomodulated reflectance spectroscopy (PR) of GaSbxAs1–x shows a reduction of the fundamental bandgap energy as well as an increase of the spin-orbit splitting energy with increasing x. The VBAC model predicts that these shifts are the result of a hybridization of the extended valence band states of GaAs with the localized states of the impurity atoms, which induce an upward movement of the valence band edge. Extrapolation of the model to other III-(Sb,Bi)-V alloys is also discussed. (© 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
She Who Shall Not Be Named: The Women That Women's Organizations Do (and Do Not) Represent in the Rulemaking Process

Abstract Though the concept of intersectionality has been in circulation for nearly 30 years and women's organizations have long been criticized for failing to prioritize the concerns of women of color, poor women, and LGBTQ women, more research is needed to determine precisely why women's organizations do and do not discuss those intersectional identities during policy debates. This study analyzes 1,021 comments that women's organizations submitted to rulemakers to test a series of hypotheses about how women's organizations’ references to women's intersectional identities increase or decrease depending on the organization's primary constituency and ideology, the proposed rule's target population, and other features of the policy-making context. Using automated text analysis and a series of models, it shows that women's organizations do discuss intersectionally marginalized women in their comments. However, not all subgroups of women are equally represented during the process. Women's organizations focus on women's sexual orientations and gender identities more than their races, ethnicities, nationalities, or socioeconomic statuses. Intersectionally marginalized women also tend to receive the most attention when commenters are from organizations that are explicitly focused on representing intersectionally marginalized women and when bureaucrats include references to intersectionally marginalized women in their proposed rules.
Stopless: a real-time garbage collector for multiprocessors

We present Stopless: a concurrent real-time garbage collector suitable for modern multiprocessors running parallel multithreaded applications. Creating a garbage-collected environment that supports real-time on modern platforms is notoriously hard,especially if real-time implies lock-freedom. Known real-time collectors either restrict the real-time guarantees to uniprocessors only, rely on special hardware, or just give up supporting atomic operations (which are crucial for lock-free software). Stopless is the first collector that provides real-time responsiveness while preserving lock-freedom, supporting atomic operations, controlling fragmentation by compaction, and supporting modern parallel platforms. Stopless is adequate for modern languages such as C# or Java. It was implemented on top of the Bartok compiler and runtime for C# and measurements demonstrate high responsiveness (a factor of a 100 better than previously published systems), virtually no pause times, good mutator utilization, and acceptable overheads.
MEMPHIS: New Framework for Realistic Virtual Engineering

In the manufacturing industry, they are using various concepts and solutions in order to reduce time and costs in the product development. This article introduces an approach that enables Virtual Engineering and links engineering applications with Virtual Reality (VR) solutions. Thus an environment is provided to implement virtual design reviews and enable the application of virtual prototyping methods. Middleware for Exchanging Machinery and Product Data in Highly Immersive Systems (MEMPHIS) enables interoperability between the IT infrastructure for engineering and VR applications to interconnect existing information and extend that knowledge to a VR application. MEMPHIS provides several interfaces for integrating commercial Product Lifecycle Management applications and provides enriched VR data in standard formats. Interoperability and enriched VR information during product development can reduce the Time to Market. Development/ manufacturing costs are reduced by avoiding geometrical defects and errors in product design, product assembly, and usability through simulation of product production processes. Productivity can be increased by providing an environment for collaboration where there is convenient and transparent access to the information required for the manufacturing process.
Hypoxia does not alter angiotensin converting enzyme activity in hamster pulmonary microvessels.

Studies were initiated to investigate the effects of hypoxia on the conversion of angiotensin I (AI) to angiotensin II (AII) in microvessels of the lung. Using the technique of allografting neonatal lung tissue into the cheek pouch of normal hamsters, the microvessels of the lung, pulmonary arterioles, and venules could be visualized and manipulated by direct in vivo microscopy. The microvessels of the lung were studied 7-10 days after allografting by anesthetizing the hamster with pentobarbital (6.0 mg/100 g body weight i.p.) and then preparing the lung tissue for observation. The tissue was suffused with a Ringer's bicarbonate solution bubbled with a normal (20% O2-5% CO2-75% N2) or a low (95% N2-5% CO2) oxygen mixture. After equilibration, a pulmonary arteriole or venule was selected for observation, and the vessel geometry was recorded. Then, a micropipette containing either AI or AII was positioned alongside the vessel, and the agent was delivered continuously for 2 minutes. Lumen diameter was recorded continually for 8-10 minutes. This procedure was repeated until both angiotensins were tested on pulmonary arterioles and venules under conditions of a normal and low oxygen environment. This protocol was repeated on cheek pouch microvessels that did not contain pulmonary allografts. Both AI and AII produced rapid decreases in the lumen diameters of all microvessels tested. This vasoconstriction was greater for AII, and the oxygen environment did not alter the response. Conversion of AI to AII was not altered by the oxygen environment, and the relative conversion was similar in the microvessels of the lung and cheek pouch. (ABSTRACT TRUNCATED AT 250 WORDS)
Clinical Significance of Isolated Peri-Appendiceal Lesions in Patients With Left Sided Ulcerative Colitis

Background Ulcerative colitis is classically described as a condition originating in the rectum and extending proximally towards the cecum. In recent years, a discontinuous peri-appendiceal lesion has been described. Our aim was to evaluate the risk of progression to pancolitis in patients presenting with an isolated peri-appendiceal lesion on ileocolonoscopy. Methods Endoscopy databases at three tertiary care centers were searched for patients undergoing ileocolonoscopy for diagnosis or surveillance of ulcerative colitis. Patients with isolated periappendiceal lesions as well as histologically confirmed left sided colitis were enrolled. Controls were defined as patients with left-sided ulcerative colitis without evidence of peri-appendiceal inflammation. The main outcome was the need for escalation of therapy to systemic corticosteroids, immunomodulators or biologic agents. Secondary outcomes were progression to pancolitis or requirement for colectomy. A secondary analysis of other risk factors for proximal extension/progression of colitis was also performed. Results We identified 228 patients with ulcerative colitis, 123 were included in the analysis. Four point eight percent of patients had isolated peri-appendiceal lesions. In the group with peri-appendiceal lesions, 47.4% required escalation of therapy vs. 70% in the control group (P = 0.53). There was no difference in progression to pan-colitis or colectomy rates between the two groups. Progression was not predicted by inflammatory markers, age, gender, initial Mayo UC score or IBD therapy utilization. Conclusions The presence of isolated peri-appendiceal lesions is not a risk factor for future escalation of therapy for ulcerative colitis and is not correlated with proximal extension of disease.
Characterization of Arctic Sea Ice Thickness Using High-Resolution Spaceborne Polarimetric SAR Data

In this paper, we have investigated the relationship between the depolarization effects and the wintertime sea ice thickness in the landfast ice region where smooth thick first-year ice (FYI) and deformed old ice coexisted by using C- and X-band spaceborne polarimetric synthetic aperture radar (SAR) data (RADARSAT-2 and TerraSAR-X). We have found a strong correlation between the in situ sea ice thickness and the SAR-derived depolarization factors (copolarized correlation and cross-polarized ratio). The observed relationships have demonstrated not only a categorical difference between FYI and multiyear ice (MYI) but also a one-to-one continuity in the scatter plots, rather than being clustered. It clearly shows that the observed correlations are not merely from the categorical difference in scattering mechanism between FYI and MYI and that there might exist a one-to-one relationship between thickness and depolarization factors at least in our deformed ice case. This suggests that depolarization factors could be effective SAR parameters in the estimation of wintertime sea ice thickness. Numerical model simulations explained some portions of the correlation by employing multiple scattering on the sea ice surface and volume scattering within the low-density subsurface layer.
Finite quotients of the multiplicative group of a finite dimensional division algebra are solvable

We prove that finite quotients of the multiplicative group of a finite dimensional division algebra are solvable. Let D be a finite dimensional division algebra having center K and let N ⊆ D× be a normal subgroup of finite index. Suppose D×/N is not solvable. Then we may assume that H := D×/N is a minimal nonsolvable group (MNS group for short), i.e., a nonsolvable group all of whose proper quotients are solvable. Our proof now has two main ingredients. One ingredient is to show that the commuting graph of a finite MNS group satisfies a certain property which we denote property (3 12 ). This property includes the requirement that the diameter of the commuting graph should be ≥ 3, but is, in fact, stronger. Another ingredient is to show that if the commuting graph of D×/N has the property (312 ), then N is open with respect to a nontrivial height one valuation of D (assuming without loss, as we may, that K is finitely generated). After establishing the openness of N (when D×/N is an MNS group) we apply the Nonexistence Theorem whose proof uses induction on the transcendence degree of K over its prime subfield, to eliminate H as a possible quotient of D×, thereby obtaining a contradiction and proving our main result.
The International Transferability of Immigrants' Human Capital Skills

This paper uses the approach in the under/over education literature to analyze the extent of matching of educational level to occupational attainment among adult native born and foreign born men in the U.S., using the 2000 Census. Overeducation is found to be more common among recent labor market entrants, while undereducation is more likely among older workers. Married men, veterans and those living in metropolitan areas are also more likely to be overeducated. Among immigrants, greater pre-immigration labor market experience is associated with poorer job matches, presumably due to the less than perfect international transferability of skills. A longer duration in the U.S., however, is associated with a lower probability of being overeducated and a greater probability of being undereducated. This is consistent with immigrants being favorably selected for occupational advancement but this effect becomes realized only after overcoming the disadvantages of the less than perfect international transferability of their pre-immigration skills.
A Robust Decentralized Job Scheduling Approach for Mobile Peers in Ad-hoc Grids

The increasing capabilities and spreading of mobile technology raise the opportunity to integrate potentially unstable mobile devices as resources into grids. In this work, we contribute by proposing and evaluating a robust decentralized job scheduling approach for mobile peers forming an ad-hoc grid. The scheduling approach is based on a first come first serve strategy executed locally by each peer. Additionally, the peer performs matchmaking between a job's requirements and the device's capabilities autonomously. Coordination between mobile peers is based on job queues shared within a distributed virtual shared memory (VSM). By applying proactive and reactive fault tolerance mechanisms we were able to increase the robustness of the scheduler. A prototypical implementation using the VSM CORSO, Java, and Condor ClassAds demonstrates the feasibility of our approach. The conducted experiments show that the job loss ratio and the average job response time can be decreased by adding fault tolerance mechanisms.
Improving Coverage in Functional Testing

Input-predicate/output (IP/O)n-chains coverage criterion, originally proposed for black-box testing of telecommunications software, is adapted to white-box testing of programs written in block-structured languages. This criterion is based on the analysis of the effects of inputs on predicates and outputs in a program. It requires that each such effect in a program is examined at least once during testing and thus provides a means of capturing the implemented functionality and checking the consistency of the program with respect to its functional requirements. It is shown that its fault-detecting ability is higher than the all-uses criterion, and compares favorably with the required k-tuples+ criterion
On Levels in Arrangements of Curves 



Abstract. Analyzing the worst-case complexity of the k -level in a planar arrangement of n curves is a fundamental problem in combinatorial geometry. We give the first subquadratic upper bound (roughly O( nk^ 1-1/(9· 2s-3) ) ) for curves that are graphs of polynomial functions of an arbitrary fixed degree s . Previously, nontrivial results were known only for the case s=1 and s=2 . We also improve the earlier bound for pseudo-parabolas (curves that pairwise intersect at most twice) to O( nk7/9 log2/3k) . The proofs are simple and rely on a theorem of Tamaki and Tokuyama on cutting pseudo-parabolas into pseudo-segments, as well as a new observation for cutting pseudo-segments into pieces that can be extended to pseudo-lines. We mention applications to parametric and kinetic minimum spanning trees.
Haptic display of visual images

The authors describe an implemented system for touching 3D objects depicted in visual images using a two-dimensional, force-reflecting haptic interface. The system constructs 3D geometric models from real 2D stereo images. The force feedback at each position is computed to provide the sensation of moving a small ball over the surface of the 3D object.
Research Proposal : Automatic Grammar Induction and Semantic Discovery

I propose research in automatic grammar induction and discovery of semantic relationships. The former has applications in the study of language similarity, language acquisition, and numerous other fields within linguistics and language technology; the latter can improve information retrieval, information extraction, dialog systems, and automatic spelling and grammar checkers. Both are active research topics in the cross-section between linguistics and computer science, and I feel that the two can be combined into something that is better than the sum of its parts. To this end, I will construct and evaluate a system capable of extracting grammatical and semantic information from unannotated corpora (and thereby for any language). Work on the grammar portion of this system has already begun, the results so far are encouraging, and it appears that, to a certain extent, I have independently arrived at some of the same ideas as those behind the Adios system, which is developed jointly by the Cornell and Tel Aviv universities and which I will study further. In my work, I will consider not only phrase grammars, but also rules for phonology, morphology, and discourse. I will then extend this system to also extract semantic information from the corpora presented to it, allowing a deeper and more thorough analysis. Here, I will explore to what extent this can be done with little or no additional data outside the corpora themselves.
Using blended learning to increase learner support and improve retention

Improving retention and identifying ‘at risk’ learners are high profile issues in higher education, and a proposed solution is to provide good learner support. Blending of online learning with classroom sessions offers the potential to use a virtual learning environment to deliver learning activities, and to support learners using a distance learning model. Online tracking can also help to target ‘at risk’ learners quickly. In an action research project to improve retention, a blended module with proactive tutor support was compared with a previous cohort of the module and with similar classroom-only modules where there was no focus on learner support. Learners were also interviewed and the tutor kept records of the learner contact time. The resulting improved coursework submission rate was attributed to learner motivation as a result of peer and tutor support. The total teaching time was no greater in this model, although the workload distribution changed, and the tutor needed to be highly skilled in e-learning.
Design and Synthesis of Hydroxyethylene-Based BACE-1 Inhibitors Incorporating Extended P1 Substituents

Novel BACE-1 inhibitors with a hydroxyethylene central core have been developed. Modified P1´ and extended P1 substituents were incorporated with the aim to explore potential interactions with the S1´ and the S1-S3 pocket, respectively, of BACE-1. Inhibitors were identified displaying IC50 values in the nanomolar range, i.e. 69 nM for the most potent compound. Possible inhibitor interactions with the enzyme are also discussed.
