Security Enhancement of Firewall Policies in Virtual Private Network

Optimizing firewall policies are crucial for improving network performance. The key technical challenge is that firewall policies cannot be shared across domains because a firewall policy contains confidential information and even potential security holes, which can be exploited by attackers. A virtual private network allows roaming users to access some resources as if that computer were residing on their home organization’s network. Although VPN technology is very useful, it imposes security threats on the remote network because its firewall does not know what traffic is flowing inside the VPN tunnel. To address this issue, VGuard was proposed, a framework that allows a policy owner and a request owner to collaboratively determine whether the request satisfies the policy without the policy owner knowing the request and the request owner knowing the policy. However two of the main challenges are the increasing number of classification rules, amount of traffic and network line speed. In order to make the above proposed approach better, this paper presents a traffic-aware top-N firewall approximation algorithm as an enhancement to the previous approach. This algorithm is used for selecting the top-N most frequently matched subset of rules from the original ruleset. The goal is to obtain Top-N rules that cover as much traffic as possible while preserving the dependency relationships that an overall higher packet classification throughput can be achieved.

MARKET ORIENTATION, ORGANIZATIONAL LEARNING, INNOVATION AND PERFORMANCE: KEYS TO THE SUSTAINABILITY OF NON-PROFITS

The purpose of this paper is to review literature, exploring the relationships between the concepts market orientation, organizational learning, innovation and performance in nonprofit organizations. To understand the nature of these concepts in the nonprofit context, the authors will discuss their application to nonprofit organizations. It questioned the use of management methodologies in these organizations and suggests the investigation of its application to improve its performance. The management of nonprofit organizations should move to another setting, unlike the informality that characterizes them. The question which arises is this reality that these organizations as complex organizations, should strive to implement new management tools that enable them to achieve sustainability, while they seek to achieve their social mission in the universe that are inserted. Thus, the authors propose a conceptual model that relates the concepts above and presents the hypotheses to be tested. They conclude by suggesting the application of the empirical model NPO management as a line of future research. The paper presented, which is part of a broader work of a doctoral thesis, refers mainly to literature.
A process-based model of methane consumption by upland soils

This study combines a literature survey and field observation data in an ad initio attempt to construct a process-based model of methane sink in upland soils including both the biological and physical aspects of the process. Comparison is drawn between the predicted sink rates and chamber measurements in several forest and grassland sites in the southern part of West Siberia. CH4 flux, total respiration, air and soil temperature, soil moisture, pH, organic content, bulk density and solid phase density were measured during a field campaign in summer 2014. Two datasets from literature were also used for model validation. The modeled sink rates were found to be in relatively good correspondence with the values obtained in the field. Introduction of the rhizospheric methanotrophy significantly improves the match between the model and the observations. The Q10 values of methane sink observed in the field were 1.2–1.4, which is in good agreement with the experimental results from the other studies. Based on modeling results, we also conclude that soil oxygen concentration is not a limiting factor for methane sink in upland forest and grassland ecosystems.
Four suspensions for transtibial prosthetics: a case-study

Suspension, Gait efficiency; Functional performance Objectives The harmony between the residual limb and the prosthesis with an effective and comfortable suspension system allows the amputee to fully continue their daily living activities. With this study authors intended to measure gait efficiency and conclude whether the suspension systems tested differ in the various transtibial prostheses, based on the data provided by indirect calorimetry. Methodology Functional performance that each suspension system allows will be approached by analyzing quantitative variables such as gait efficiency through indirect calorimetry using Lin-Chan protocols, which uses 5 different treadmill speeds. Results Gait efficiency analysis of the four suspension systems (2 suction; 1 PIN; 1 VASS) showed that when comparing the four models, the most functional suspension system was the prosthesis with the active vacuum suspension system (VASS) with lower values for mlO2/kg/m and higher distance than other suspension systems. Conclusion –Differences in results of the tests carried out in the various suspension systems prove that indirect calorimetry is sensitive in the assessment of the identified variables and is a viable tool in the analysis of gait efficiency in amputees, proving that the VASS suspension system is what presents a greater efficiency in walking and so a higher functionality.

It is found that migrant population associated with age and age at marriage follow simple linear regression model and four parameters polynomial model correspondingly.
Tracing outflows in the AGN forbidden region with SINFONI

AGN driven outflows are invoked in numerical simulations to reproduce several observed properties of local galaxies. The z > 1 epoch is of particular interest as it was during this time that the volume averaged star formation and the accretion rate of black holes were maximum. Radiatively driven outflows are therefore believed to be common during this epoch. We aim to trace and characterize outflows in AGN hosts with high mass accretion rates at z > 1 using integral field spectroscopy. We obtain spatially-resolved kinematics of the [OIII]5007 line in two targets which reveal the morphology and spatial extension of the outflows. We present J and H+K band SINFONI observations of 5 AGNs at 1.2 < z < 2.2. To maximize the chance of observing radiatively driven outflows, our sample was pre-selected based on peculiar values of the Eddington ratio and the hydrogen column density of the surrounding interstellar medium. We observe high velocity (~600-1900 km/s) and kiloparsec scale extended ionized outflows in at least 3 of our targets, using [OIII]5007 line kinematics tracing the AGN narrow line region. We estimate the total mass of the outflow, the mass outflow rate, and the kinetic power of the outflows based on theoretical models and report on the uncertainties associated with them. We find mass outflow rates of ~1-10 M_sun/yr for the sample presented in this paper. Based on the high star formation rates of the host galaxies, the observed outflow kinetic power and the expected power due to the AGN, we infer that both star formation and AGN radiation could be the dominant source for the outflows. The outflow models suffer from large uncertainties, hence we call for further detailed observations for an accurate determination of the outflow properties to confirm the exact source of these outflows.
"Notes on Vocative case: a case study in clause structure"

1. Vocative Case in modern syntax: two questions One of the major achievements of modern syntax is that all the different relations that are standardly referred to as ‘Case assignments’ have been unified under a single syntactic relation, namely a specifier – head relation holding between a noun phrase and a proper functional head (see Chomsky 1995 and references cited there). In this paper I would like to address some questions concerning the nature of the so called ‘Vocative Case’ which naturally arise under such perspective. As a premise, let me notice that the literature concerning Vocative Case is unusually scarce, especially if compared with the literature concerning other Cases. I think that this is not accidental, for the very existence of a specific morphological Vocative Case has been often denied as will be shown on the base of some citations from classical works in the field. In this paper I will focus on two conceptually distinct questions:
First-year university students ’ academic success

Considering the pivotal role of academic adjustment for student success, it is important to gain insight into how several motivational and behavioural factors affect academic adjustment and the extent to which academic adjustment influences student success. This empirical study investigated how intrinsic motivation, academic self-efficacy, selfregulated study behaviour and satisfaction with the chosen degree programme influenced academic adjustment in university and how these variables and adjustment affected three important indicators of student success: grade point average (GPA), attained number of credits (ECTS) and intention to persist. The sample consisted of 243 first-year university students in the Netherlands. Structural equation modelling showed that academic adjustment was influenced by intrinsic motivation, self-regulated study behaviour and degree programme satisfaction, which together explained 72% of the variance in adjustment. Motivational and behavioural variables did not influence GPA and credits directly but through academic adjustment. Furthermore, only satisfaction with the degree programme predicted intention to persist. These results point to the importance of academic adjustment in predicting university GPA and credits and the pivotal role of satisfaction with the degree programme in predicting intention to persist. Universities could integrate the development of self-regulated study skills—the biggest contributor to academic adjustment—in the first-year programme. Moreover, looking at the importance of students’ satisfaction with the programme, communication and collaboration between secondary schools and universities should be enhanced in order to Eur J Psychol Educ (2018) 33:749–767 DOI 10.1007/s10212-017-0347-8 * Els C.

Level of satisfaction in patients/attendants admitted with traumatic brain injury at an advanced ER/Casualty in a Tertiary Care Teaching Hospital

Background: The objective of the present study was to develop an instrument that could be helpful to measure the level of satisfaction with hospital services in cases of traumatic brain injuries. Methods: The present pilot study was a prospective analysis of traumatic brain injury patients. The study was approved by the institutional ethical committee. The data was collected regarding demographics, clinical presentation, management offered, complications and survival. Patient satisfaction was measured by a validated questionnaire with six domains: information, human care, comfort, visiting, intimacy, and cleanliness. The data was collected in self-administered questionnaire to measure attendants’ desires and expectations for a broad spectrum of frequently used services in a hospital. Attendants indicated their level of satisfaction by selecting responses ranging from poor=1, fair=2, good=3, very good=4 and excellent=5. Each domain was scored from excellent to poor, with higher scores indicating higher levels of patient satisfaction. Results: During the pilot study period, data for a total 86 patients was collected. The mean age was 36.81 years (Age range 6-73 years, median-35.5 years). Mean hospital stay was 9.25 days (range 2-35 days, median 6.9 days). In present study almost all the patients were brought by close relatives. Most of the patients belonged to the low socio-economic status (coolie 33/86, farmers’ 17/86). Sixty six patients made good recovery, 14 had moderate disability and 6 patients had severe disability at the time of discharge. The overall satisfaction level was classified into excellent, very good, good, average and poor. Details of the level of satisfaction and most of the time it was excellent to very good and good level of satisfaction. There were no averages or poor response. Conclusions: We believe the scores obtained from the questionnaire from present pilot study can serve as baseline against which to compare the results from future surveys.
A paradigm in architectural education: Kolb’s Model and learning styles in studio pedagogy

In line with “learner-centered” teaching paradigm (Weimer 2002), enhancing learning experiences in design studio should be a fundamental concern positioned at the center of attention in current discourses of architectural education research. This focus warrants further studies on students’ cognitive patterns and learning processes to identify what goes in learners’ minds, and how learning style variations affect knowledge acquisition. In the applied and overlapping fields of architecture, urban design, and landscape architecture, drawing on cognitive studies and Kolb’s Experiential Learning Model have important implications for integrating and transferring learning in seminar/lectures to studio environments. Cognitive psychologists make distinctions between “declarative” recalling of factual knowledge and “procedural” knowledge of knowing to perform activities (Bruning, Schraw, and Ronning 2004:46-48). “Structural knowledge” is referred to “as internal connectedness, integrative understanding, or as conceptual knowledge” that “is used to develop procedural knowledge to solving domain problems,” involving the integration of declarative knowledge (Jonassen, Beissner, & Yacci 1993: 5). Kolb (1984) similarly describes how “learning is the process whereby knowledge is created through the transformation of experience. Knowledge results from the combination of grasping experience and transforming it (Kolb 1984:41). ” Various knowledge types are integral to learning in architectural education; thus, this paper proposes a course design model that investigates various knowledge implications. On the one hand, the studio environment, although productive and rich in learning experiences and professional opportunities, sometimes can be stressful, where teacher/peer pressures and competitive attitudes negate learning potential and lead to unproductive results. A one-semester long studio might not always offer the required time or space to learn procedural knowledge, for example, to solve complicated urban design problems, and in particular, to recognize multiple patterns affecting an urban/suburban context. However, lectures/seminars, on the other hand, usually attempt to convey significant declarative knowledge in one semester, sometimes without addressing actual application to studio projects. The objective of this paper is to propose a learner-centered pedagogical framework that applies Kolb’s Experiential Learning Model and integrates and foster significant interplay between the learning of declarative knowledge in theory classes and the procedural knowledge needed to solve design problems in studio environments.
Blanching effect on the quality and shelf life of pea

The effects of blanching on the peas were investigated to determine the quality and shelf life of the pea during storage in deep freeze for six months. The experiment was carried out Completely Randomized Design and there were five treatments using four different blanching times as 1 min, 3min, 5 min, and 7 min with fixed temperature of 80 0 C. The data were analyzed under computerized statistical methods of M-stat and Duncan’s Multiple Range Test was used to compare the means. The chemical compositions were analyzed and the following results were investigated: the dry matter percentages were slightly decreased over storage duration. The acidity contents of blanching peas were slightly decreased and P H contents slightly increased on storage. The Vitamin C and β-carotene contents were decreased after increasing the blanching time. Peroxidase and catalase inactivation time of enzyme for blanching of peas represents the most enzymes were inactivated rapidly as temperature rises to 80 O C with 7 minutes blanching . Therefore, the study results showed that the frozen peas were stored well in home deep freeze up to four months blanching at 80 0 C for 7 minutes.

THERMAL FIELD SIMULATION OF A TUNGSTEN FILAMENT LAMP REFERRING TO ITS LIFETIME

This article deals with the calculation of the filament lifetime regarding the evaporation of tungsten mass from the filament surface. The filament of an incandescent lamp represents an electric resistor. Its resistance depends on the intensity of tungsten mass evaporation. If an electrical power is applied, it is converted to heat that causes the temperature rise in the filament. The intensity of tungsten mass evaporation depends strongly on the filament temperature. Therefore, the modelling of filament geometry and simulation of its temperature field is described as well. The finite element method (FEM) has been used for the temperature field solution. The steady temperature fields were derived in the five solution steps. Calculation of separate solutions differs with reference to the filament diameter reduction in the process of evaporation. Actually, the change of the diameter represents decreasing of the filament material (tungsten). Following this change, the assumed lamp life is evaluated subsequently. The result of the life calculation was compared with the life data listed in the work standard for 7528 car lamp produced by OSRAM that we have modelled. The temperature field obtained by FEM was compared with thermovision camera measurement.
The Impact of Regional Economic Cooperation on the Ethiopian Manufacturing Sector : The Case of Common Market for Southern and Eastern Free Trade Area ( COMESA-FTA )

A computable partial equilibrium (CPE) model is employed to quantify the welfare implications of COMESA-FTA on the Ethiopian manufacturing sector. The results of the model indicate that the value of imports have expanded as a result of tariff elimination on imports from COMESA member countries. This increase in value of imports led to consumption expansion, implying an increase in consumer’s surplus. There is also negative budgetary implication implied by the loss in tariff revenue. The net welfare effect, which is the combined effect determined by the relative magnitudes these effects, reveals a welfare loss of 0.06% of GDP. Over all, the static welfare effect of complete tariff removal on commodities imported from COMESA member countries appeared to be welfare depressing. However, this should be treated with caution since it does not show the dynamic effects relating to market size, efficiency gains and economies of scale that might have been attained in the long run. Moreover, this analysis focuses only on the manufacturing sector, it doest not indicate the economy wide effects of complete tariff removal on imported commodities from COMESA member countries.
Do difficulties with emotions inhibit help-seeking in adolescence? The role of age and emotional competence in predicting help-seeking intentions

We examined whether adolescents who are poor at identifying, describing, and managing their emotions (emotional competence) have lower intentions to seek help for their personal-emotional problems and suicidal ideation, as observed in adult studies. We also examined whether age moderated the relationship between competence and help-seeking. Two hundred and seventeen adolescents completed measures of emotional competence, help-seeking, hopelessness, and social support. Results indicated that adolescents who were low in emotional competence had the lowest intentions to seek help from informal sources (i.e., family and friends) and from some formal sources (e.g., mental health professionals), and the highest intentions to seek help from no-one. There was one important age-related qualification: difficulty in identifying and describing emotions was associated with higher help-seeking intentions amongst young adolescents but lower intentions among older adolescents. Social support, hopelessness, and sex could not entirely explain these relationships. Thus, even those who had high quality social support had less intention to use it if they were low in emotional competence.
