An Analysis of Ontology Mismatches; Heterogeneity versus Interoperability

The growth of the Internet has revitalised research on the integration of heterogeneous information sources. Integration efforts face a trade off between interoperability and heterogeneity. Important integration obstacles arise from the differences in the underlying ontologies of the various sources. In this paper we investigate the impediments to integration, focussing on ontologies. In particular, we present a classification of ontology mismatches (distinguishing conceptualisation mismatches and explication mismatches as its main categories), and discuss how each of the mismatch types can be dealt with. The idea is that knowing which ontology mismatches are difficult to deal with may contribute to finding a balance between heterogeneity and interoperability.
Liquidity Traps and Monetary Policy: Managing a Credit Crunch

We study a model with heterogeneous producers that face collateral and cash-in-advance constraints. A tightening of the collateral constraint results in a credit-crunch-generated recession that reproduces some features of the financial crisis that unraveled in 2007 in the United States. We use the model to study the effects, following a credit crunch, of alternative monetary and fiscal policies. (JEL E31, E44, E52, E62, G01, H63)
Recent Developments in Mems-Based Micro Fuel Cells

Micro fuel cells (µ-FC) represent promising power sources for portable applications. Today, one of the technological ways to make µ-FC is to have recourse to standard microfabrication techniques used in the fabrication of micro electromechanical systems (MEMS). This paper shows an overview on the applications of MEMS techniques on miniature FC by presenting several solutions developed throughout the world. It also describes the latest developments of a new porous siliconbased miniature fuel cell. Using a silane grafted on an inorganic porous media as the proton-exchange membrane instead of a common ionomer such as Nafion  , the fuel cell achieved a maximum power density of 58 mW cm -2 at room temperature with hydrogen as fuel.
Accelerate the Face Detection Optimization with Edge detection and the Discrete Cosine Transform (DCT)

This study presents a new method for accelerating and optimizing face detection, while preserving a high level of accuracy. This method uses local features that are extracted using block-base discrete cosine transform (DCT). This study uses edge detection method for face recognition with ICA algorithms. The technique used for edge detection is Laplacian of Gaussian (LOG). To find objects, face position and local information the discrete cosine transform is used. Here the main idea is edge detection and finding face position in the picture for DCT processing. Edge detection was applied for accelerating image processing. In this paper we use CohnKanade AU-Coded Facial Expression Database.
Adolescent Sexual Risk Reduction and the Theory of Planned Behavior: Moderation Effects and the Role of Previous Experience

The theory of planned behavior (TPB) is a useful model for understanding socialcognitive determinants (i.e. attitude, perceived norms, and perceived behavioral control) of sexual risk reduction among adolescents. However, research using the TPB has emphasized main effects and has not considered the possibility of moderated associations. In addition to testing main effects, this study assessed the interactions between TPB constructs and investigated the influence of previous sexual experience when predicting adolescents’ intentions to use condoms and delay sexual activity. Results indicate that the TPB functions differently depending on previous sexual experience and type of risk reduction behavior. Perceived norms were the only consistent predictor of intentions for condom use and delay. Attitude moderated perceived behavioral control when predicting condom use intentions among sexually experienced youth. However, no other interaction effects were detected. Future directions for research and implications for practice are discussed.

All I want for Christmas is recovery – changes in employee affective well-being before and after vacation

ABSTRACT The goal of this empirical study was to provide a detailed picture of the short- and long-term development of affective well-being before, during, and after vacation. Specifically, we investigated employees’ positive and negative affect and examined whether the Christmas holiday casted its shadow on employees’ affect during December. Further, we identified which factors (from both the work and private life domain) modulated the change in employees’ affect before the vacation and which factors during and after vacation influenced the speed of fade-out effects. We used longitudinal research data with two measurements per week over a 15-week period and collected data from 145 white-collar workers, resulting in a total of 2062 measurements. Multilevel modelling revealed that those who reported less work and personal tasks in December had a steeper increase in well-being before their vacation. Those who enjoyed more recovery experiences during their vacation and the following weekends and those who started work with lower levels of unfinished tasks enjoyed slower fade-out effects after vacation. Pleasant anticipation tended to change the development of affective well-being before Christmas. The study provides a fine-grained picture of the change in well-being over time and indicates how employees may particularly benefit from their vacation.
The Embedding Capacity of Information Flows Under Renewal Traffic

Given two independent point processes and a certain rule for matching points between them, what is the fraction of matched points over infinitely long streams? In many application contexts, e.g., secure networking, a meaningful matching rule is that of a maximum causal delay, and the problem is related to embedding a flow of packets in cover traffic such that no timing analysis can detect it. We study the best undetectable embedding policy and the corresponding maximum flow rate-that we call the embedding capacity-under the assumption that the cover traffic can be modeled as an arbitrary renewal process. We find that computing the embedding capacity requires the inversion of a very structured linear system that, for a broad range of renewal models encountered in practice, admits a fully analytical expression in terms of the renewal function of the processes. This result enables us to explore the properties of the embedding capacity, obtaining closed-form solutions for selected distribution families and a suite of sufficient conditions on the capacity ordering. We test our solution on real network traces, which shows a remarkable match for tight delay constraints. A gap between the predicted and the actual embedding capacities appears for looser constraints, and further investigation reveals that it is caused by inaccuracy of the renewal traffic model rather than of the solution itself.
Convergence Analysis of a Stochastic Projection-free Algorithm

This paper presents and analyzes a stochastic version of the Frank-Wolfe algorithm (a.k.a. conditional gradient method or projection-free algorithm) for constrained convex optimization. We first prove that when the quality of gradient estimate improves as ${\cal O}( \sqrt{ \eta_t^{\Delta} / t } )$, where $t$ is the iteration index and $\eta_t^{\Delta}$ is an increasing sequence, then the objective value of the stochastic Frank-Wolfe algorithm converges in at least the same order. When the optimal solution lies in the interior of the constraint set, the convergence rate is accelerated to ${\cal O}(\eta_t^{\Delta} /t)$. Secondly, we study how the stochastic Frank-Wolfe algorithm can be applied to a few practical machine learning problems. Tight bounds on the gradient estimate errors for these examples are established. Numerical simulations support our findings.
The role of spiritual leadership in fostering inclusive workplaces

Inclusion is of critical importance to creating healthier workplaces, if the ongoing dynamic of workforce diversity is taken for granted. The purpose of this paper is to designate the role of spiritual leadership in fostering more humane and inclusive workplaces. ,The authors review the extant literature on two distinct research streams, inclusion and inclusive leadership, and spiritual leadership, elaborate a mediation model, identify antecedents and outcomes, and articulate a set of propositions reflecting key findings. ,The authors advance a conceptual model according to which inclusive practices founded on spiritual values will mediate the positive relationship between spiritual leadership and a climate for inclusion. They argue that calling and membership as components of spiritual wellbeing will reinforce employees’ experience of both uniqueness and belongingness, thus affecting their perceptions of inclusion and inducing multi-level beneficial outcomes. ,Spiritual leadership assumes a preeminent role in embracing and valuing diversity: it embodies a potential for positioning inclusive ideals more strategically, in view of enabling employees unfold their genuine selves and experience integration in work settings. ,Spiritual leadership helps inclusive goals to be situated in their societal context; inclusion is thus viewed as both an organizational and societal good, embedded in social contexts, and pertinent to corporate vision, mission and philosophy. ,The paper examines spiritual leadership as a predictor of climates for inclusion. Drawing on spiritual values, spiritual leaders display a strong potential for inclusion, facilitating diverse employees to experience feelings of both belongingness and uniqueness in work settings that assume high societal relevance.
Acoustic Emission during Fatigue Crack Growth in Aluminium Plates

Acoustic emission (AE) is potentially an ideal technique for health monitoring of large structures due to the small number of sensors required and its high sensitivity. There has been much research conducted to characterize and provide qualitative understanding of the AE process in small specimens. Unfortunately, it is difficult to extend these results to real structures as the experimental data is dominated by geometric effects due to the small size of the specimens. The aim of this work is to provide a characterization of elastic waves emanating from fatigue cracks in plate-like structures. Fatigue crack growth was initiated in large 6082 T6 aluminium alloy plate specimens subjected to cyclic loading in the laboratory. A large specimen was used to eliminate signal reflections from the specimen edges and to enable signals from different wave modes to be separated in time. The signals were recorded using both resonant and non-resonant transducers attached to the surface of the specimens. Large numbers of AE signals were detected due to active fatigue crack propagation during the experiment. Analysis of experimental results from multiple crack growth events was used to characterize the modal and angular distributions of the radiated elastic waves. Experimental results are compared with finite element predictions to examine the mechanism of AE generation at the crack tip.
A Guide to Job Enrichment and Redesign.

The use of traditional methods for job design and redesign can have a negative impact on productivity and employee morale. Four alternatives to the traditional approach are job enrichment, the job characteristics model, Japanese-style management, and quality-of-worklife approaches. The theories of job enrichment and the job characteristics model are based on job content. Japanese-style management techniques focus on strong teamwork, job harmony, and group goals. The quality-of-life approaches are based on improving an organization’s design. A suggested procedure for implementing a large-scale job redesign program involving 12 steps is outlined.
Market Reaction to Corporate News and the Inuence of the Financial Crisis

Having obtained a complete dataset of corporate press releases issued between April 2006 and August 2009, we analyze the stock price reactions to various types of corporate events. Besides confirming the previously-documented empirical regularities about the reaction to financial news, we also document a strong market response to news about corporate strategy, customers & partners, products & services, management changes, and legal issues. In addition, we find that return volatility generally increases and liquidity decreases in the month after the announcement. Investigating separately the time periods before and during the financial crisis, we observe that the response to certain types of news has changed. For example, during the crisis period, news that signal higher and more stable future cash flows, such as announcements about corporate restructuring, new corporate partners, successful research completion, FDA approvals, and legal settlements lead to more positive price reactions. On the other hand, events that are perceived to decrease future cash flows and increase their uncertainty, such as announcements about legal troubles, FDA rejections, and failed research efforts have a more negative effect on stock prices. Moreover, announced plans to raise funds through equity or debt offerings are perceived less negatively, and announcements of share buybacks lead to even higher abnormal returns than in the pre-crisis period. We also show that during the more uncertain crisis period, news announcements tend to lead to larger volatility increases. JEL classification: G01, G10, G14, G30.
Isolation and characterization of neural precursor cells from the Sox1–GFP reporter mouse

We have made use of a reporter mouse line in which enhanced green fluorescence protein (GFP) is inserted into the Sox1 locus. We show that the GFP reporter is coexpressed with the Sox1 protein as well as with other known markers for neural stem and progenitor cells, and can be used to identify and isolate these cells by fluorescence‐activated cell sorting (FACS) from the developing or adult brain and from neurosphere cultures. All neurosphere‐forming cells with the capacity for multipotency and self‐renewal reside in the Sox1–GFP‐expressing population. Thus, the Sox1–GFP reporter system is highly useful for identification, isolation and characterization of neural stem and progenitor cells, as well as for the validation of alternative means for isolating neural stem and progenitor cells. Further, transplantation experiments show that Sox1–GFP cells isolated from the foetal brain give rise to neurons and glia in vivo, and that many of the neurons display phenotypic characteristics appropriate for the developing brain region from which the Sox1–GFP precursors were derived. On the other hand, Sox1–GFP cells isolated from the adult subventricular zone or expanded neurosphere cultures gave rise almost exclusively to glial cells following transplantation. Thus, not all Sox1–GFP cells possess the same capacity for neuronal differentiation in vivo.
Employee Status and the Consequences of Perceived Organizational Support

Incorporating organizational support and status theory, this study examines whether employees’ status moderates both the relationship between perceived organizational support (POS) and affective organizational commitment (AOC) as well as POS-AOS-job performance relationships. Based on two studies using different types of status measures (i.e., objective and subjective), our findings demonstrate that both the POS-AOC relationship and the entire mediation process were moderated by employee status such that low-status employees showed a greater improvement in effects. This study represents a novel attempt to clarify the critical role of individual status, which has largely been neglected in the field of I/O psychology and organizational behavior, in the complex mechanism of POS and subsequent outcomes.
Teaching Critical Thinking: Some Lessons From Cognitive Science

This article draws six key lessons from cognitive science for teachers of critical thinking. The lessons are: acquiring expertise in critical thinking is hard; practice in critical-thinking skills themselves enhances skills; the transfer of skills must be practiced; some theoretical knowledge is required; diagramming arguments (“argument mapping”) promotes skill; and students are prone to belief preservation. The article provides some guidelines for teaching practice in light of these lessons.
The Syntactic and Semantic Processing of Mass and Count Nouns: An ERP Study

The present study addressed the question of whether count and mass nouns are differentially processed in the brain. In two different ERP (Event-Related Potentials) tasks we explored the semantic and syntactic levels of such distinction. Mass and count nouns typically differ in concreteness, hence the effect of this important variable was factorially examined in each task. Thus the stimuli presented were: count concrete, count abstract, mass concrete or mass abstract. The first experiment (concrete/abstract semantic judgment task) involved the interaction between the N400 concreteness effect and the Mass/Count condition, revealing a substantial effect between mass and count nouns at the semantic level. The second experiment (sentence syntactic violation task) showed a Mass/Count distinction on left anterior negativity (LAN) and on P600 components, confirming the difference at the syntactic level. This study suggests that the brain differentiates between count and mass nouns not only at the syntactic level but also at the semantic level. Implications for our understanding of the brain mechanisms underlying the Mass/Count distinction are discussed.
Group Size, Coordination, and the Effectiveness of Punishment in the Voluntary Contributions Mechanism: An Experimental Investigation

We examine the effectiveness of the individual-punishment mechanism in larger groups, comparing groups of four to groups of 40 participants. We find that the individual punishment mechanism is remarkably robust when the marginal per capita return (MPCR), i.e. the return to each participant from each dollar that is contributed, is held constant. Moreover, the efficiency gains from the punishment mechanism are significantly higher in the 40-participant than in the four-participant treatment. This is true despite the coordination problems inherent in an institution relying on decentralized individual punishment decisions in the context of a larger group. It reflects increased per capita expenditures on punishment that offset the greater coordination difficulties in the larger group. However, if the marginal group return (MGR), i.e. the return to the entire group of participants, stays constant, resulting in an MPCR that shrinks with group size, no such offset occurs and punishment loses much but not all of its effectiveness at encouraging voluntary contributions to a public good. Efficiency is not significantly different from the small-group treatment.
Is There Social Consensus Regarding Researcher Conflicts of Interest?

Consensus around what constitutes researcher conflicts of interest (COIs) and awareness of their influence on our research are two critical steps in ensuring the integrity of our science. In this research, data were collected from individual scholars via 2 surveys 5 years apart and from journals and associations to examine the level of social consensus and moral awareness among scholars, journals, and associations regarding researcher COIs. Although we observed increases in level of social consensus and moral awareness between 2012 and 2017, results still revealed limited agreement about what relationships constitute a COI and limited awareness about the presence of and the ethical issues surrounding COIs. Although all journals and associations we examined supported COI disclosure, most did not provide researchers with detailed COI-related information, guidance, or disclosure tools. Limited social consensus and moral awareness regarding COIs is problematic because it inhibits the recognition, disclosure, and management of COIs and limits ethical decision making. We need to continue and enhance discussions about COIs and aim to create consensus and awareness where we do not have it with the goal of reducing potential scientific misconduct related to COIs.
Self‐efficacy in undergraduate students with dyslexia: a mixed methods investigation.

It may be thought that gaining a place at university confers self‐belief on students with dyslexia; after all, they have succeeded in their academic studies. Our research explored self‐efficacy beliefs in university students with and without dyslexia. An Academic Self‐Efficacy Scale and a Sources of Academic Self‐Efficacy Scale were completed by 44 university students. These scores were compared between dyslexic and non‐dyslexic students. Interviews were conducted with eight participants to gain a fuller understanding of how their self‐efficacy beliefs develop. Undergraduate students with dyslexia scored lower than students without dyslexia on four out of the five measures of academic self‐efficacy. The dyslexic students reported role models, teachers and school performance as factors influencing their motivation toward academic work. The research suggests that university students with dyslexia still need interventions to help boost their self‐efficacy profiles, despite the level of success they have achieved in gaining a place at university.

Happiness as a Reward for Torture: Is Participation in a Long-Distance Triathlon a Rational Choice?

This study applies prospect theory to an assessment of actual behavior. Loss aversion, reference dependence, and diminishing sensitivity are conceptualized through survey respondents’ perceptions of physical and mental torture during training for and competition in long-distance triathlons. Regression results show that frequent thoughts of giving up during the race negatively affect happiness after the race, while mental torture during training and race is negatively associated with happiness in the weeks after the race. Satisfaction with race outcome positively affects happiness, suggesting that achieving individual goals is more important than absolute performance in terms of finishing times and ranks.
