A trusted security information sharing mechanism

Security Operations Center (SOC) is a unit inside or outside an organization that monitors and deals with information security incidents, on a technical level. In this paper, a trusted security incident information sharing mechanism among SOCs is proposed. The information needed to share among SOCs to prevent incident dispersions usually were just the time of occurrence, origin of attack, consequence, severity and path of attack. In the proposed mechanism, we aim to share the minimum information required. Secure data transferred paths can be used. We hope the adopting of the mechanism may increase the willing of sharing security information among SOCs.

Endogenous estrogen and acetylcholine-induced vasodilation in normotensive women.

Acute exogenous estrogen administration enhances endothelial function in postmenopausal women. To evaluate the effect of endogenous estrogen on endothelium-dependent vasodilation, in 10 fertile normotensive women (age range 45 to 51 years) we studied the changes in forearm blood flow (strain-gauge plethysmography) induced by intrabrachial acetylcholine (0.15, 0.45, 1.5, 4.5, 1.5 micrograms.100 mL-1.min-1), an endothelium-dependent vasodilator, or sodium nitroprusside (1, 2, 4 micrograms.100 mL-1.min-1), an endothelium-independent vasodilator, in basal conditions and within 1 month after ovariectomy. As control subjects, 10 matched healthy women were also evaluated. In basal condition, vasodilation to acetylcholine and sodium nitroprusside was similar in patients and control subjects. Ovariectomy was followed by endogenous estrogen deprivation (from 71.6 +/- 31.3 to < 12 pg/mL) and was associated with a significant (P < .01) reduction in acetylcholine-induced vasodilation compared with baseline (maximum percent increase in forearm blood flow: baseline 568.2 +/- 47.1%; ovariectomy 309.5 +/- 37.4%); the response to sodium nitroprusside was unaffected by ovariectomy (maximum percent increase in forearm blood flow: baseline 526.4 +/- 36.5%; ovariectomy 454.7 +/- 47.2%; P = NS). In 6 of 10 patients, the study was repeated after 3 months of estrogen replacement therapy (17 beta-estradiol, 50 micrograms/d by transdermal patches). Exogenous estrogen restored acetylcholine-induced vasodilation (maximum percent increase in forearm blood flow: 548.9 +/- 43.1%; P < .01 versus ovariectomy), which was no longer different from baseline, whereas the response to sodium nitroprusside was not affected (maximum percent increase in forearm blood flow: 480.2 +/- 39.3%; P = NS). These results suggest a protective role of endogenous estrogen on endothelium-dependent vasodilation in the forearm vascular bed of normotensive women.
Predicting Spontaneous Big Five Behavior with Implicit Association Tests

According to theories brought forward recently, implicit measures based on reaction times, for instance Implicit Association Tests (IATs), should predict spontaneous behavior better than explicit measures. We applied five IATs to the measurement of the Big Five personality factors and tested whether the IATs predicted spontaneous behavior. The results show that, although implicit and explicit measures of personality dimensions were related at times, the correlations between them and with behavior suggest that these constructs should be differentiated. IATs predicted spontaneous behavior, but explicit measures did not. In contrast, explicit measures, but not IATs, were related to transparent self-ratings of behavior.
Dynamic Mobile Charger Scheduling in Heterogeneous Wireless Sensor Networks

Recent advances in energy transfer technology is boosting the development of renewable sensor networks. To sustain such a network, a mobile robot travels from node to node to recharge each sensor before its battery runs out. Consider each node's recharge as a real-time task, the robot needs to serve these tasks by their deadlines. This represents a class of challenging mobility scheduling problems, where the nodes' deadlines and spatial distribution are often at odds with each other. In this paper, we focus on the scenario where nodes have heterogeneous energy consumption rates, and our goal is to maximize the percentage of nodes alive. We formulate this scheduling problem and prove its NP-completeness. To solve this problem, we propose a spatial dependent task scheduling algorithm, which quantifies the impact of scheduling proximate tasks on the other tasks. With extensive simulations, we reveal the trade-offs of existing solutions under a wide range of network scenarios. Our evaluation results show that our algorithms out-perform classical TSP scheduler by up to 10% and 85% in terms of coverage ratio and average tardiness, respectively.
Mobile interaction using paperweight metaphor

Conventional scrolling methods for small sized display in PDAs or mobile phones are difficult to use when frequent switching of scrolling and editing operations are required, for example, browsing and operating large sized WWW pages.In this paper, we propose a new user-interface method to provide seamless switching between scrolling and other operations such as editing, based on "Paperweight Metaphor". A sheet of paper that has been placed on a slippery table is difficult to draw on. Therefore, in order to write or draw something on the sheet of paper, a person must secure the paper with his/her palm to avoid the paper from moving. This will be a good metaphor to design switching operation of scroll and editing modes.We have made prototype systems by placing a touch sensor under each PDA display where user's palm will be hit. Three application programs - map browser, WWW browser, and photograph browser - that switch between scrolling and other operation modes depending on sensor output have been developed. We have carried out user tests on this mode switching method and have received favorable feedback on the same.
About estimation of quality of clustering results via its stability

We know that there are many clustering methods for the case of a known/unknown number of clusters. Clustering is a result of fulfillment of some stopping criterion. Usually, optimisation of some quality criterion is performed or iterative processes are accomplished. How to estimate the quality of clustering obtained by some method? Is the obtained clustering result corresponding to the objective reality or some stopping criterion of the algorithm is made and we have obtained only some partition? Here, a practical approach and the common general criteria based on an estimation of the stability of clustering are submitted. The criterion does not use any probabilistic assumptions or distances in feature space. For some well-known clustering algorithms, efficient methods for computing the introduced stability criteria according to the training set are obtained. Some illustrative real and artificial examples for various situations are shown.
Drug loading, drug release and in vitro degradation of poly(caprolactone) electrospun fibers

In this study, model drug of Fluorescein Isothiocyanate-Dextran (FD70S) was incorporated into poly(caprolactone) (PCL) electrospun fibers. Drug loading was successful and drug release was measured by using microplate reader. The result showed FD70S was successfully released from PCL electrospun fibers. In order to investigate the biodegradable ability of PCL electrospun fibers, in vitro degradation was investigated for 107 days by immersing PCL electrospun fibers in phosphate buffer saline (PBS) which mimics extracellular fluid. Electrospun fibers degraded slowly and were not fully degraded. Fibers became more random and the average fiber diameters decreased from 350 nm to 240 nm after degradation of 107 days.
Individualism, GNP, Climate, And Pronoun Drop

Affluence and climate are related to individualism, suggesting the importance of the material environment on culture. However, the symbolic environment, as represented by language, may also play a significant role. The effects of gross national product (GNP) per capita, latitude, and pronoun drop (whether the subject of a sentence can be dropped) as variables that tap the material and symbolic environments on Hofstede's individualism were examined. GNP per capita and latitude had overall positive effects on individualism, but this was moderated by pronoun drop. The effect of economic affluence on culture was greater, but the effect of climate smaller, in the countries whose language does not permit pronoun drop than in those countries where pronouns can be dropped in utterances. A moderating effect of symbolic factors on the material environnment-culture relationship was discussed.
Distinct Characteristics of Indole-3-Acetic Acid and Phenylacetic Acid, Two Common Auxins in Plants

The phytohormone auxin plays a central role in many aspects of plant growth and development. IAA is the most studied natural auxin that possesses the property of polar transport in plants. Phenylacetic acid (PAA) has also been recognized as a natural auxin for >40 years, but its role in plant growth and development remains unclear. In this study, we show that IAA and PAA have overlapping regulatory roles but distinct transport characteristics as auxins in plants. PAA is widely distributed in vascular and non-vascular plants. Although the biological activities of PAA are lower than those of IAA, the endogenous levels of PAA are much higher than those of IAA in various plant tissues in Arabidopsis. PAA and IAA can regulate the same set of auxin-responsive genes through the TIR1/AFB pathway in Arabidopsis. IAA actively forms concentration gradients in maize coleoptiles in response to gravitropic stimulation, whereas PAA does not, indicating that PAA is not actively transported in a polar manner. The induction of the YUCCA (YUC) genes increases PAA metabolite levels in Arabidopsis, indicating that YUC flavin-containing monooxygenases may play a role in PAA biosynthesis. Our results provide new insights into the regulation of plant growth and development by different types of auxins.
UniPad: orchestrating collaborative activities through shared tablets and an integrated wall display

UniPad is a face-to-face, digital simulation for use in classroom settings that runs on shared tablets and a wall display. The goal is to encourage students to talk, collaborate and make decisions together in real-time, by switching between working on shared 'small group' devices and a 'whole classroom' public display - instead of working by themselves using their own device. It is intended to improve peer discussion and teacher involvement by focusing and constraining shared attention at different stages of an activity. The domain for this study is finance management. The system was designed using an iterative, participatory design method with expert finance educators and then trialed using an in-the-wild study at a school. The findings show how the set-up helped in facilitating verbal participation in the classroom. We discuss how lightweight, multi-device shared technology systems, such as UniPad, can be designed and used for a range of classroom activities.
Untangling Employee Loyalty: A Psychological Contract Perspective

ABSTRACT: Although business ethicists have theorized frequently about the virtues and vices of employee loyalty, the concept of loyalty remains loosely defined. In this article, we argue that viewing loyalty as a cognitive phenomenon—an attitude that resides in the mind of the individual—helps to clarify definitional inconsistencies, provides a finer-grained analysis of the concept, and sheds additional light on the ethical implications of loyalty in organizations. Specifically, we adopt the psychological contract perspective to analyze loyalty's cognitive dimensions, and treat loyalty as an individual-level construction of perceived reciprocal obligations. Based upon this perspective, we present a three-tiered framework of loyalty that provides a psychologically informed definition of the concept, specifies the variety of obligation types that loyalty can imply, and anticipates the potential for asymmetrical loyalty configurations between employers and employees. We use the framework to articulate moral issues associated with both symmetrical and asymmetrical loyalty configurations and discuss the implications of the framework for theory and practice.
The Moral Narratives of Economists

Moral narratives have a substantive effect on the research conclusions of economists. This is one of the findings from a recent survey of economists that we conducted, which found a relationship between views on empirical economic propositions and moral judgments. This finding may help to answer the question this symposium asks: Why don’t U.S. economists ever support the welfare state and oppose the regulatory state, or vice versa? We find the same moral narrative supports or opposes both states in tandem. To support one and oppose the other would be morally incoherent.
Augmentation of Endothelium‐Independent Flow Constriction in Pial Arteries at High Intravascular Pressures

The effects of an increase in intraluminal pressure and flow on the diameter and active smooth muscle tone of pial arteries was studied in perfused segments. Resistance arteries (approximately 250-300 /μm i.d.) were perfused under controlled pressure and flow conditions, and changes in arterial diameter registered with an automated video device. In any particular segment, diameter measurements were normalized to that observed at 5 mm Hg. Changes in active wall force were determined by relating the observed diameter under a particular set of conditions to the diameter at the same intramural pressure when smooth muscle tone was inhibited (calcium-free physiological saline solution) and to the diameter when smooth muscle cells were activated close to maximum (KC1; 89 mM). At 60 mm Hg, the diameter decrease of 21% in the absence of flow represented stretch-induced tone. No additional changes in diameter were encountered with a flow of 20 μl/min. Diameter decreased a further 7% at 100 /nl/min. When intraluminal pressure was 90 mm Hg, diameter decreased 39% without flow. Additional constriction of 10% and 19% occurred at flows of 20 and 100 μl\Jmin, respectively. At the higher pressure, the vasoconstriction occasioned by flow was significantly greater than that at the lower pressure. After endothelium inactivation by passing hypo-osmotic Krebs' solution followed by air through the segment, mean diameter was less at each combination of pressure and flow, although this difference did not reach statistical significance. The diameter reductions to increases in pressure from 60 to 90 mm Hg and to flow at 40 μl/min were not altered by endothelium inactivation. We conclude that the vasoconstrictor effects of flow as well as pressure are augmented at high intravascular pressures and that these constrictor effects are independent of the endothelium.
Beyond Prefix-Based Interactive Translation Prediction

Current automatic machine translation systems require heavy human proof-reading to produce high-quality translations. We present a new interactive machine translation approach aimed at providing a natural collaboration between humans and translation systems. As such, we grant the user complete freedom to validate and correct any part of the translations suggested by the system. Our approach is then designed according to the requirements placed by this unrestricted proof-reading protocol. In particular, the ability of the system to suggest new translations coherent with the set of potentially disjoint translation segments validated by the user. We evaluate our approach in a user-simulated setting where reference translations are considered the output desired by a human expert. Results show important reductions in the number of edits in comparison to decoupled post-editing and conventional preﬁx-based interactive translation prediction. Additionally, we provide evidence that it can also reduce the cognitive overload reported for interactive translation systems in previous user studies.
Reduction of control input variance of feed drive systems using sliding-mode control with non-linear sliding surface

Ball-screw drives have been widely used in industrial applications delivering high precision motion in work machines, such as machine tools, where both high speed and positioning accuracy are required. Most of control schemes used in industrial application have a constant damping ratio leads to make a tradeoff between the low overshoot and small settling time of the system. This paper presents a novel sliding-mode controller with a non-linear sliding surface to improve the machining accuracy of ball-screw feed drive systems. Unlike the conventional sliding-mode control design, the proposed non-linear sliding surface varies due to the output so that the damping ratio of the system changes from its initial low value to its final high value as the output changes from its initial value to the reference point. Hence, the proposed algorithm allows a closed-loop system to simultaneously achieve low overshoot and a small settling time, resulting in a smaller error and control input variance. Computer simulation and experimental results for a ball-screw feed drive system show that the proposed approach reduces the control input variance by an average of 19.1% than using the conventional linear sliding surface.
MicroRNAs in Neurotoxicity

MicroRNAs are gaining importance as regulators of gene expression with the capability to fine-tune and modulate cellular events. The complex network with their selective targets (mRNAs/genes) pave way for regulation of many physiological processes. Dysregulation of normal neuronal activities could result in accumulation of substances that are detrimental to neuronal functions and subsequently result in neurotoxicity. Neurotoxicity-mediated pathophysiological conditions could then manifest as diseases or disabilities like Parkinson's and Alzheimer's which have debilitating implications. Such toxicity can be a result of individuals predisposed due to genetic inheritance or from other sources such as brain tumours. Neurotoxicity can also be brought about by external agents like drugs and alcohol as well as brain injury with miRNAs playing a pivotal role in diseases. It is therefore vital to understand the expression of these microRNAs and their impact on neuronal activities. In this paper, we discuss some of the neuronal pathophysiological conditions that could be caused by dysregulated microRNAs.
Student Involvement in Individualized Education Program Meetings

We conducted a review of the literature to investigate interventions designed to increase students' involvement in their individualized education program (IEP) process. Sixteen studies were identified and analyzed in terms of six variables: purpose, participants/setting, design, dependent variables, independent variable, and results. Our findings suggest that students with widely varying disabilities can be actively involved in the IEP process. Our results also indicate that both published curricula designed to teach students skills to enhance their participation prior to IEP meetings and person-centered planning strategies are effective in increasing students' involvement in their IEP meetings, as substantiated through direct observation; scores on measures of self-determination; and/or feedback from participants, parents, and teachers. We discuss the results in terms of implications for practice and research, the need for future studies to assess the impact of student participation on students' daily lives, and the need for institutions of higher education to prepare teachers to include students in the IEP process.
Multi-Criteria Optimization of Regulation in Metabolic Networks

Determining the regulation of metabolic networks at genome scale is a hard task. It has been hypothesized that biochemical pathways and metabolic networks might have undergone an evolutionary process of optimization with respect to several criteria over time. In this contribution, a multi-criteria approach has been used to optimize parameters for the allosteric regulation of enzymes in a model of a metabolic substrate-cycle. This has been carried out by calculating the Pareto set of optimal solutions according to two objectives: the proper direction of flux in a metabolic cycle and the energetic cost of applying the set of parameters. Different Pareto fronts have been calculated for eight different “environments” (specific time courses of end product concentrations). For each resulting front the so-called knee point is identified, which can be considered a preferred trade-off solution. Interestingly, the optimal control parameters corresponding to each of these points also lead to optimal behaviour in all the other environments. By calculating the average of the different parameter sets for the knee solutions more frequently found, a final and optimal consensus set of parameters can be obtained, which is an indication on the existence of a universal regulation mechanism for this system.The implications from such a universal regulatory switch are discussed in the framework of large metabolic networks.
Chinese “Little Emperor”, cultural values and preferred communication sources for university choice

Purpose – The purpose of this paper is to investigate how Chinese cultural values influence “Little Emperors'” choice of study destination; and their preferred communication sources for university choice.Design/methodology/approach – University students from the People's Republic of China (PRC) in New Zealand were surveyed with an instrument based on Schwartz's “Values survey” and the understanding that cultural values are a powerful force shaping consumers' motivations, lifestyles and product choices. A central‐location (libraries, lecture theatres) sampling strategy was employed.Findings – The results from the research suggest that Chinese cultural values have an impact on “Little Emperor's” choice of international tertiary education and their preferred communication sources for university choice. The study shows that New Zealand society appeals for its low corruption and high level of honesty and fairness which are attractive to these “Little Emperors” because these values help to reinforce group harmo.
- 1-Raptor Code-Based Video Multicast over IEEE 802 . 11 WLAN

In this paper, we apply a Raptor code-based forward error correcting scheme right above the medium access control (MAC) layer in order to ensure the reliability of the video multicast over IEEE 802.11 wireless LANs (WLANs). Both Raptor code rate and physical layer (PHY) transmission rate are dynamically adapted according to the channel condition. We consider a number of MAC schemes for data transmission in order to enhance the efficiency. The performance of the proposed scheme is evaluated in terms of the perceived video quality, i.e., peak signal-to-noise ratio (PSNR).
