THE EFFECT OF TRANSFORMATIONAL LEADERSHIP ON ORGANIZATIONAL IDENTIFICATION AND PERCEIVED CORPORATE REPUTATION: A UNIVERSITY SAMPLE

This study has been done in a sample university to find out the effects of transformational leadership on organizational identification and perceived corporate reputation and to see whether organizational identification plays a part in this effect. To see the effects and to find out whether organizational identification plays a part in this effect, a survey was carried out on 214 academic and administrative staff of a private university. The results of the survey were analyzed through regression analysis. According to these results, there is a positive and significant relationship between transformational leadership, organizational identification and corporate reputation. Apart from this, it has been understood that organizational identification plays an important part on the relationship between transformational leadership and perceived corporate reputation
Class, race – and place: immigrants’ self-perceptions on inclusion, belonging and opportunities in Stockholm and Barcelona

ABSTRACT Based on eighty-one in-depth interviews with immigrants and stakeholders performed in Stockholm and Barcelona, this article examines whether the relationship to place can mitigate the negative effects of rejection that racialized immigrants and minorities perceive from the ethnic majority society. The immigrant respondents’ perceptions and lived experiences of exclusion and discrimination lend support to the argument that it is necessary to link race and class in order to understand the particular “immigrant disadvantage,” but also reflect how attachment to the city or neighbourhood where they live can contribute to a sense of belonging: the respondents overall feel more included in Barcelona, where every day interethnic contacts are more frequent than in Stockholm.
Isolation and structural characterization of natural deuterated lipids and oils from microorganisms

The formation and structural investigation of planar bilayers from synthetic lipids and natural extracts is described. The bilayers were used as model membrane systems for the investigation and quantification of the molecular mechanisms of the membrane-binding antifungal drug Amphotericin B, primarily by neutron reflectometry. Different membrane models of increasing complexity were investigated, with ergosterol or cholesterol included to mimic fungal and mammalian cell membranes, respectively. The extraction, chemical analysis and preparation of hydrogenous and deuterated lipid mixtures from yeasts are presented together with the optimization of the deposition process of supported lipid bilayers on silicon substrates using Quartz Crystal Microbalance with Dissipation monitoring to create relevant natural model membranes for the neutron scattering experiments. The effects of deuteration on the lipid composition in two different yeasts, the methylotrophic Pichia pastoris and the pathogenic Candida glabrata are detailed and is shown to be useful for understanding the modulation of the lipids accessible from these microorganisms. Model membranes from the synthetic lipid 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine were initially characterized and compared to those formed by the phospholipids or the total lipids extracted from the yeasts, mainly using neutron reflectometry but also membrane diffraction. Finally, the relationship between the lipid composition and the response to Amphotericin B was investigated. Although different behavior of the drug is observed in fungal and mammal membrane mimics, the composition and degree of complexity of the model systems employed were shown to affect the findings and the interpretation of the mechanisms involved in the interaction of the drug with the membranes. The differences found between synthetic and natural lipid systems demonstrate the relevance of the newly developed model membranes from lipids extracted from biomass.
Source-Based Path Selection: The Data Plane Perspective

In source-based path selection, the sender chooses the path to the destination from a set of available paths and embeds the forwarding information in the packets. Future Internet proposals have employed this scheme to realize the benefits of source routing without the inherent scalability problems of path computation at the source. Furthermore, to address the security concerns of packet-carried forwarding state, these proposals leverage cryptographic primitives (e.g., Message Authentication Codes) per packet in the data plane. However, the implications on the forwarding performance of these novel routing schemes have not been studied in detail. In this paper, we study the data plane of source-based path selection schemes. We take SCION---a future Internet proposal---as an example and sketch its data plane implementation. We implement a software switch that can forward up to 140 million minimum-sized packets per second (limited by the hardware I/O subsystem) and can achieve line-rate throughput of 120 Gbps.
Cross-layer optimization for m-health SVC multiple video transmission over LTE uplink

M-health services are expected to become increasingly relevant in the management of emergency situations, enabling real-time support of remote medical experts. In this context, the transmission of health-related information from an ambulance to a remote hospital is a challenging task, due to the variability and the limitations of the mobile radio link. In particular, the transmission of multiple video streams can improve the efficacy of the tele-consultation service, but requires a large bandwidth to meet the desired quality, not always guaranteed by the mobile network. In this paper we propose a novel cross-layer adaptation strategy for multiple SVC videos delivered over a single LTE channel, which dynamically adjusts the overall transmitted throughput to meet the actual available bandwidth, while being able to provide high quality to diagnostic video sequences and lower (but fair) quality to less critical ambient videos. After having introduced a realistic LTE uplink scenario, including an advanced resource allocation strategy, we show through numerical simulations that the proposed solution is capable to achieve an optimal end-to-end video quality for both the diagnostic and the ambient videos.
Autonomic and Dependable Computing: Moving Towards a Model-Driven Approach

The rapidly increasing complexity of computing systems is driving the movement towards autonomic systems that are capable of managing themselves without the need for human intervention. Without autonomic technologies, many conventional systems suffer reliability degradation and compromised security. Autonomic management techniques reverse this trend. This study describes the roles and functions of various autonomic components, and systematically reviews past and current approaches that have been/are being developed to address specific areas of the autonomic computing environment that focus on improving system dependability including both reliability and security concerns. Analyzing past research can lead to the design of a more advanced, dependable autonomic computing system. A novel and promising prototypical system that is a work-in-progress will be presented finally.
Analysis of Measured and Predicted Acoustics From an XV-15 Flight Test

Flight acoustic and vehicle state data from an XV-15 acoustic flight test are examined. Flight predictions using TRAC are performed for a level flight (repeated) and four descent conditions (including a BVI). The assumptions and procedures used for TRAC flight predications as well as the variability in flight measurements, which are used for input and comparison to predictions, are investigated in detail. Differences were found in the measured vehicle airspeed, altitude, glideslope, and vehicle orientation (yaw, pitch, and roll angle) between each of the repeat runs. These differences violate some of the prediction assumptions and significantly impacted the resulting acoustic predictions. Multiple acoustic pulses, with a variable time between the pulses were found in the measured acoustic time histories for the repeat runs. These differences could be attributed in part to the variability in vehicle orientation. Acoustic predictions that used the measured vehicle orientation for the repeat runs captured this multiple pulse variability. Thickness noise was found to be dominant on approach for all the cases, except the BVI condition. After the aircraft passed overhead, broadband noise and low frequency loading noise were dominant. The predicted LowSPL time histories compared well with measurement on approach to the array for the non-BVI conditions and poorly for the BVI condition. Accurate prediction of the lift share between the rotor and fuselage must be known in order to improve predictions. At a minimum, measurements of the rotor thrust and tip-path-plane angle are critical to further develop accurate flight acoustic prediction capabilities.
A semi-autonomous communication robot — A field trial at a train station

This paper reports an initial field trial with a prototype of a semi-autonomous communication robot at a train station. We developed an operator-requesting mechanism to achieve semi-autonomous operation for a communication robot functioning in real environments. The operator-requesting mechanism autonomously detects situations that the robot cannot handle by itself; a human operator helps by assuming control of the robot. This approach gives semi-autonomous robots the ability to function naturally with minimum human effort. Our system consists of a humanoid robot and ubiquitous sensors. The robot has such basic communicative behaviors as greeting and route guidance. The experimental results revealed that the operator-requesting mechanism correctly requested operator's help in 85% of the necessary situations; the operator only had to control 25% of the experiment time in the semi-autonomous mode with a robot system that successfully guided 68% of the passengers. At the same time, this trial provided the opportunity to gather user data for the further development of natural behaviors for such robots operating in real environments.
Towards a Model to Understand the Influence of Trust in Knowledge Sharing Decisions

In this paper, we analyze the role of trust in knowledge sharing decisions. Based on experiences in a practical implementation of knowledge sharing support in a organization, we provide a basic model of trust in terms of the beliefs of the trusting party, both in its role as knowledge supplier and knowledge receiver. The model takes into account different aspects of the knowledge, the characteristics of the exchange partner (e.g., competence and integrity) and contextual factors. We have used this model to organize the features of Castelfranchi’s socio-cognitive knowledge-sharing operations [3]. The overall goal of the framework is to provide a starting point for an analysis of the role of personal attitudes in the successes and failures of organizational knowledge flows.
Performance Enhancement of Binary Randomized Arithmetic Coding for Multimedia Encryption

Arithmetic coding provides an effective mechanism for removing redundancy in the encoding of data. Although arithmetic coding offers extremely high coding efficiency, it provides little or no security as traditionally implemented. A modified randomized arithmetic coding is proposed in this paper, which achieves encryption by inserting randomization in the compression process using a secret key. The proposed approach consists of two cascaded modules. The first one is called randomized arithmetic coding (RAC) while the second one is the XOR module. The joint RAC/XOR encryption paradigm incurs extremely low computational and implementation costs. Security analysis shows that the proposed scheme is robust against cryptanalytic attacks and makes it an ideal choice for real time data transmission.
Maximal subbundles and Gromov invariants

In this article we explicitly compute the number of maximal subbundles of rank $k$ of a generically stable bundle of rank $r$ and degree $d$ over a smooth projective curve $C$ of genus $g\ge 2$ over $\C$, when the dimension of the quot scheme of maximal subbundles is zero. Our method is to describe the this number purely in terms of the Gromov invariants of the Grassmannian and then use the formula of Vafa and Intriligator to compute them.
A Software Based Installation to Assist Self-Reflection

In (Nardelli 2010) we have proposed a classification of interactive digital artworks based on some of their more meaningful IT characteristics. An interactive digital artwork is any artwork where digital technology is an essential component and which is interactive. The definition of our classification convinced us of the importance not just to reflect on these themes as observers but also to enter ourselves in this area and to try out to deal firsthand with the subject matter.
An improved technique to avoid deafness in MANET

MANET (Mobile Ad-hoc Network) is a web or network of mobile nodes which communicates with everyone with no any ant access point. Deafness is a major problem in this network. When nodes are communicating with everyone at that time when one node is busy with another node, the node waiting from communicating with the nodes among them, don't have receive slot, this situation is called deafness. In general, the deafness are occurring when a node is again and again wants to communicate with other node, but that's no so much more effective, due to the Y are currently changing into certain another antenna beam or unreachable, in the base paper node are communicating with everyone by broadcasting link id of each other in this case if node is highly moveable than communication can't be take place only using the link id. In our proposed work node have straightly communicated with everyone via direct antenna and if one node forwards data to other node and destination node is busy or out of range than route node contain this data for further communication whenever node is free route node communicate with this node and send ack to source node we also raise the strength of buffer capacity and also enhance the buffer space for enhance the network performance.
Building the case for independent monitoring of food advertising on Australian television

Abstract Objective To provide an independent monitoring report examining the ongoing impact of Australian self-regulatory pledges on food and drink advertising to children on commercial television. Design Analysis of food advertisements across comparable sample time periods in April/May 2006, 2007, 2009, 2010 and 2011. The main outcome measure comprised change in the mean rate of non-core food advertisements from 2006 to 2011. Setting Sydney free-to-air television channels. Subjects Televised food advertisements. Results In 2011 the rate of non-core food advertisements was not significantly different from that in 2006 or 2010 (3·2/h v. 4·1/h and 3·1/h), although there were variations across the intervening years. The rate of fast-food advertising in 2010 was significantly higher than in 2006 (1·8/h v. 1·1/h, P < 0·001), but the same as that in 2011 (1·5/h). Conclusions The frequency of non-core food advertising on Sydney television has remained essentially unchanged between 2006 and 2011, despite the implementation of two industry self-regulatory pledges. The current study illustrates the value of independent monitoring as a basic requirement of any responsive regulatory approach.
Integrating sentiment analysis and term associations with geo-temporal visualizations on customer feedback streams

Twitter currently receives over 190 million tweets (small text-based Web posts) and manufacturing companies receive over 10 thousand web product surveys a day, in which people share their thoughts regarding a wide range of products and their features. A large number of tweets and customer surveys include opinions about products and services. However, with Twitter being a relatively new phenomenon, these tweets are underutilized as a source for determining customer sentiments. To explore high-volume customer feedback streams, we integrate three time series-based visual analysis techniques: (1) feature-based sentiment analysis that extracts, measures, and maps customer feedback; (2) a novel idea of term associations that identify attributes, verbs, and adjectives frequently occurring together; and (3) new pixel cell-based sentiment calendars, geo-temporal map visualizations and self-organizing maps to identify co-occurring and influential opinions. We have combined these techniques into a well-fitted solution for an effective analysis of large customer feedback streams such as for movie reviews (e.g., Kung-Fu Panda) or web surveys (buyers).
Efficacy of External Beam Radiation-Based Treatment plus Locoregional Therapy for Hepatocellular Carcinoma Associated with Portal Vein Tumor Thrombosis

Background. Portal vein tumor thrombosis (PVTT) is a common event in advanced hepatocellular carcinoma (HCC). The optimal treatment for these patients remains controversial. Methods. A retrospective review of 149 patients who had unresectable HCC associated with PVTT between January 2005 and December 2012 was performed. Outcomes related to external beam radiation-based treatment were measured, and clinicopathological features and parameters affecting prognosis were analyzed as well. Results. The radiotherapeutic response of PVTT was an important element that affected the overall treatment response of HCC. Serum α-fetoprotein < 400 ng/mL, the presence of a radiotherapeutic response on PVTT, and receiving additional locoregional therapy were significant prognostic factors affecting the survival of patients. Patients who had received additional locoregional therapy obtained a better outcome, and six of them were eventually able to undergo surgical management with curative intent. Conclusion. The outcome of HCC associated with PVTT remains pessimistic. In addition to the current recommended treatment using sorafenib, a combination of external beam radiotherapy targeting PVTT and locoregional therapy for intrahepatic HCC might be a promising strategy for patients who had unresectable HCC with PVTT. This approach could perhaps offer patients a favorable outcome as well as a possible cure with following surgical management.
TAT-Protein Blockade during Ischemia/Reperfusion Reveals Critical Role for p85 PI3K-PTEN Interaction in Cardiomyocyte Injury

Recent work shows that cooling protection after mouse cardiac arrest and cardiomyocyte ischemia is mediated by Akt activation. The PI3K p85 subunit can either augment or inhibit Akt activation depending on its binding to p110 or PTEN respectively. To further clarify the role of PI3K p85 in cardioprotection, we studied novel TAT-p85 fusion proteins that selectively inhibit PI3K p85 binding. We hypothesized that TAT fused p85 lacking the PTEN binding site (TAT-ΔPTEN p85) would enhance Akt phosphorylation to afford cardioprotection. Conversely, TAT fused p85 lacking the p110 binding site (TAT-Δp110p85) would decrease Akt phosphorylation and abrogate cardioprotection. Microscopy and Western blot analysis demonstrated that TAT fusion protein was transduced into cardiomyocytes within 5 min and remained more than 2 h. Inhibition of PI3K/Akt by TAT-Δp110 p85 significantly increased cell death from 44.6±2.7% to 92.5±3.4% after simulated ischemia and reperfusion. By contrast, PTEN inhibition using TAT-ΔPTEN p85 decreased cell death to 11.9±5.3%, a similar level of cardioprotection seen with past cooling studies. Additional studies with the small molecule PTEN inhibitor VO-OHpic confirmed that PTEN inhibition was highly protective against cell death induced by ischemia and reperfusion. We conclude that blockade of p85-PTEN interaction and PTEN inhibition may be promising strategies for rescuing the heart from ischemia and reperfusion injury.
Wide-Field Megahertz OCT Imaging of Patients with Diabetic Retinopathy

Purpose. To evaluate the feasibility of wide-field Megahertz (MHz) OCT imaging in patients with diabetic retinopathy. Methods. A consecutive series of 15 eyes of 15 patients with diagnosed diabetic retinopathy were included. All patients underwent Megahertz OCT imaging, a close clinical examination, slit lamp biomicroscopy, and funduscopic evaluation. To acquire densely sampled, wide-field volumetric datasets, an ophthalmic 1050 nm OCT prototype system based on a Fourier-domain mode-locked (FDML) laser source with 1.68 MHz A-scan rate was employed. Results. We were able to obtain OCT volume scans from all included 15 patients. Acquisition time was 1.8 seconds. Obtained volume datasets consisted of 2088 × 1044 A-scans of 60° of view. Thus, reconstructed en face images had a resolution of 34.8 pixels per degree in x-axis and 17.4 pixels per degree. Due to the densely sampled OCT volume dataset, postprocessed customized cross-sectional B-frames through pathologic changes such as an individual microaneurysm or a retinal neovascularization could be imaged. Conclusions. Wide-field Megahertz OCT is feasible to successfully image patients with diabetic retinopathy at high scanning rates and a wide angle of view, providing information in all three axes. The Megahertz OCT is a useful tool to screen diabetic patients for diabetic retinopathy.
Moving Forward with Self-Compassion: An Examination of Self-Compassion, Social Anxiety, and Post-Event Processing

Post-event processing (PEP) refers to a negative and prolonged rumination following anxiety-inducing social situations and is posited to maintain social anxiety. Because PEP is characterized by thoughts that are judgmental, recurring, and preoccupying, those who engage in PEP appear to lack self-compassion. Self-compassion can be conceptualized as a supportive and open attitude toward negative experiences, with the recognition that these experiences are universal. The purpose of the present research was to examine selfcompassion in the context of PEP. In the first manuscript, we found support across two, separate samples (N = 156 undergraduates; N = 150 individuals from the community seeking self-help for social anxiety and shyness) for the negative relationship between self-compassion and PEP. In the second manuscript (N = 98 socially anxious undergraduates), we found that those assigned to a self-compassion condition following a speech experienced less PEP one day later, compared to those in both the negative rumination and writing control conditions. In the third manuscript (N = 66 undergraduates), we found that negative, compared to positive, speech feedback heightened PEP when dispositional self-compassion was low, but not when it was high. Taken together, these findings suggest that self-compassion is relevant to PEP, can be induced as a means of limiting PEP, and continues to buffer against PEP amongst those high on the trait, even after receiving negative performance feedback. Given these findings, clinicians may consider self-compassion as part of treatment protocols for social anxiety and PEP.
