Divided communities : introducing the preferences of academics into the analysis of promotion

Academic employment systems have been subjected to policy-driven changes in many countries but the university sector is still governed by collegial dynamics in which academics’ views and attitudes are important. The present study, based on data from questionnaire survey responses of 4460 university faculty members in Spain, attempts to explain the preferences of academics towards the different systems of hiring and promotion in the university sector that have been in operation in the last 15 years, with varying degrees of centralization versus delegation of the evaluation processes to the local academic communities. After two reforms and eight years of operation of the current system, more than half of academics would still prefer a different model. We identify four different sets of explanatory factors conceptually linked to: academics’ self-interest, beliefs and values, personal experience and learning, and socialization and institutional factors. We find that academics’ preferences are not primarily explained by their career advancement interests. Our results show that preferences regarding the recruitment and promotion systems are strongly associated with a set of beliefs, opinions and values, especially the belief in the relative suitability of systems to guarantee a merit-based selection. Interestingly, those with university managerial experience are less likely to prefer the current model. This is also the case for those with higher academic rank, age and academic quality. No significant differences by gender were found.
Multi Layer Security for MIMO Wiretap System

The broadcast nature of physical medium makes security an important concern in wireless communication. This work proposes a cross layer security approach for Gaussian multiple-input-multiple-output (MIMO) wiretap channel. Here, RSA algorithm is used along with a physical layer dependent transmitter and receiver filter design. The transmit and receive filters are designed with an objective to minimize the mean-square error (MSE) between authenticated parties, while ensuring that the eavesdropper MSE goes beyond a certain level. The power constraint is also taken into account and optimal filters are designed through the solution of convex optimization problems. The performance of zero forcing (ZF) and Wiener filters at eavesdropper receiver is analyzed for the case when legitimate receiver uses ZF filters, under degraded and non-degraded channel conditions. We also assume that the channel state information (CSI) is known to all other parties. The filter coefficients at legitimate receiver are then used to obtain the two prime numbers required for key generation at the initial stage of RSA algorithm. Performance of the system is analyzed by plotting BER vs SNR values and using numerical simulations. Keywords—MIMO, ZF filters, wiener filetr,RSA, secrecy.
A Demonstrator of an IP-based Access Network for Broadband Multimedia Services

This paper describes a demonstrator of an IP-based access network for broadband multimedia services, which was designed to be low cost and easily manageable. In order to support broadband multimedia services, the network architecture incorporates a number of newly introduced technologies: SIP (Session Initiation Protocol) for session initiation, RSVP (resource ReSerVation Protocol) for resource reservation, and COPS (Common Open Police Service) for QoS policy management and AAA (Authentication, Authorization and Accounting). Some modules of the access network elements were implemented using the VOCAL (Vovida Open Communication Application Library) system, developed by Vovida. We report both functional and performance results obtained with the demonstrator, and traffic management experiments related with the policing, packet scheduling, resource reservation and admission control mechanisms.
Policy strategies face with future water availability using a dynamic CGE approach

The real evolution of water supply in the last year s in the province of Huesca in north-eastern Spain is taken into account to make a forecast with a 2030 time horizon. The main aim of this work is to find policy strategies to ap ply to water management to cope with future water availability integrating extreme events like droughts. For this purpose, we develop a dynamic computable g eneral equilibrium (CGE) model with water as an explicit factor of production. The main core of these strategies is focused on smoothing impacts of water constraints through an i mprovement in resources management of Irrigated agriculture. Alternative technological im provements in Irrigated agriculture are considered. In addition to technological change, we take into account Water Framework Directive (EC 2000/60) that sets up the recovery of costs of water as a central target. In a context of limits on natural resources, finding new designs for the implementation of water pricing policies could be a challenge. Thus, we assess stra tegies that combine water pricing and improved technology. The results show that it would be possible to deal with future water availability, even in presence of droughts, to reve se the long-term economy trend through policy strategies which would involve technical progress. The way to introduce technical progress in agriculture is significant. Moreover, this study co nfirms lower price volatility can improve optimal water use.
The effects of single and dual coded multimedia instructional methods on Chinese character learning

Abstract This study investigated the effects of single and dual coded instructional methods using computer-based multimedia on Chinese character learning. 42 college students with no prior knowledge of Chinese language were randomly assigned to a single coded group (text-only and animation-only) and a dual coded group (animation plus text and animation plus narration) to learn 12 concrete (pictograph) Chinese characters and 12 abstract (ideograph) Chinese characters. The results showed there was a significant difference between the single coded and the dual coded instructional methods and there was also a main effect in the character type. In addition, the findings indicated that within the single coded group, there was a significant difference between two character types and a significant difference between two single coded methods with the animation-only method leading to better achievement score than the text-only method. For the dual coded group, the results revealed a significant difference between two character types as well and a significant difference between two dual coded methods with the animation plus narration method outperforming the animation plus text method.
Access Driven Cache Timing Attack Against AES: Access Driven Cache Timing Attack Against AES

Firstly,this paper displays an access driven Cache timing attack model,proposes non-elimination and elimination two general methods to analyze Cache information leakage during AES encryption,and builds the Cache information leakage model.Next,it uses quantitative analysis to attack a sample with the above elimination analysis method,and provides some solutions for the potential problems of a real attack.Finally,this paper describes 12 local and remote attacks on AES in OpenSSL v.0. 9.8a,v.0. 9.8j. Experiment results demonstrate that: the access driven Cache timing attack has strong applicability in both local and remote environments;the AES lookup table and Cache structure decide that AES is vulnerable to this type of attack,the least sample size required to recover a full AES key is about 13;the last round AES implementation in OpenSSL v.0. 9.8j,which abandoned the T4 lookup table,cannot secure itself from the access driven Cache timing attack;the attack results strongly verify the correctness of the quantitative Cache information leakage theory and key analysis methods above.
Symptoms, aetiology, epidemiology, psychophysiology, treatment, and outcomes of developmental trauma

Developmental trauma disorder (DTD) is not formally recognised as a diagnosis in the current diagnostic systems. There has been a push for its inclusion by child psychiatrists and psychologists within the past decade. There are a multitude of symptoms associated with DTD, which can manifest differently depending on the individual and the type of trauma they have experienced. The array of symptoms participants have reported in trauma studies shows the difficulty in pinpointing exactly which individuals who have developmental trauma will experience difficulties throughout their lives. Based on previous works, a traumatic home environment is the most likely cause of DTD. Factors that may moderate developmental trauma disorder are discussed. Those at risk for DTD include: (i) children who have been separated from a parent; (ii) children who have experienced any form of maltreatment; and, (iii) people who, as infants, felt vulnerable and perceived their caregiver(s) as unpredictable. Exposure to trauma affects the entire body and trauma experienced in childhood is the most detrimental because the brain is still developing. Due to the nature of how varied and complex developmental trauma can be for each person, there is no single treatment that has been found through research that can cure developmental trauma. Pharmacological, psychosocial, and behavioural treatments are discussed. has generated quite a bit of research on developmental trauma. This paper addresses the symptoms, aetiology, epidemiology, psychophysiology, and treatments and treatment outcomes of developmental trauma. The paper concludes with a call for the inclusion of DTD in diagnostic systems, as well as more studies on treatments specifically for DTD Symptoms
Coverage of the 2010 Brazilian Presidential Elections

A framing analysis of mainstream online organizations and their bloggers and columnists on the 2010 Brazilian Presidential Elections revealed that framing do have the potential to expose ideological elements on how the media position themselves in the public sphere. Thematic and episodic frames dominated the news with a special focus on press freedom, social and economic problems, corruption and abortion. The mainstream media focused their coverage on the Workers’ Party employing primarily a critical/ adversarial tone as opposed to an interpretive analysis tone. Professional ideology mixed with political preferences both by journalists and media owners marked the Brazilian online coverage blurring the lines between the private and the public, exactly in the same way that outgoing President Lula da Silva acted during the presidential campaign. Journalism status quo emerged as a main topic in the coverage as a free press under attack quickly reacted with rage causing a rift between news organizations that criticized the outgoing president and those that supported him. Furthermore, a popular president apparently unaffected by corruption scandals and the country’s most powerful media groups confronted each other in an exhaustive and unfinished battle.
Effects of Robot Control Mode on Situation Awareness and Performance in a Navigation Task

Our ability to complete tasks in remote environments has improved with increased sophistication of robotic systems. The quality of remote task performance is driven by the quality of human interaction with robots which can be dependent upon the operator's ability to acquire situation awareness (SA) for task completion. There are, however, often critical limitations in development of SA, which are projected to have a magnified effect when operators must task and control multiple unmanned systems. In this study, we investigated the effects the mode of robot control on operator performance and ability to develop SA while navigating two robots through two mazes. Participants were randomly assigned to groups to control the robots in serial (one after another) or in parallel (at the same time) either manually or using two types of automation. The participants also viewed a systems interface to monitor the status of the robots. Results indicate that participants under serial control produced higher SA scores, though not significantly different from SA scores observed under parallel control modes. The best navigation performance was observed under parallel control with a high level of autonomy that followed a prescribed set of navigation rules. This control mode also resulted in the lowest workload scores. Participants were better able to correctly respond to SA queries for lower level, perceptual items in the robotics task as compared to higher level comprehension and projection items. Performance in the monitoring task was found to be significantly, positively correlated to participant SA.
SMEs and innovative entrepreneurship

SMEs and innovative entrepreneurship play a key role when it comes to innovation. They are engaged in the development and commercialization innovations. They are also adopters of innovations developed by other organizations, and they provide ideas and inputs to ideas generation that are exploited by large firms, universities/research organisations and other small firms. They often face larger barriers on capital and labour markets than larger established businesses. It is for that reason that multiple policy measures have been adopted to target those firms and their opportunities to engage in innovation.
Bridging the Gap between Psychology and Economics : The Role of Behavioral Finance

This article is a descriptive presentation of how behavioral finance plays key role in providing insight into how individuals’ investment behavior typically deviates from traditional economic theories. The efficient market hypothesis (EMH) and capital asset pricing model (CAPM) theories have gained prominence in modern finance platform. The adequacy of these popular, rational-based behavior theories has however, remained skeptical among many scholars including Daniel Kahneman, Amos Tversky, and Richard H. Thaler. While the EMH and CAPM theories have contributed significantly to the investment world, some scholars contend the theories fail to fully explain certain inconsistent behaviors exhibited in the investment world. Behavioral finance is a new theory that attempts to fill the void between psychology and economics by providing a better understanding of investor behavior through the theories of psychology. Investment decisions are impacted by an array of irrational behavioral biases. The article identifies some finance and economic theory anomalies such as the January effect, equity premium puzzle, and others, which shift away from the traditional economic theories. Understanding these anomalies not only would assist individuals have a sense of how investors generally behave in the investment arena but also would help in efficient capital allocation.
Development of Antibacterial Nanocomposite: Whey Protein-Gelatin-Nanoclay Films with Orange Peel Extract and Tripolyphosphate as Potential Food Packaging

Antibacterial and biodegradable whey protein isolate (WPI-) gelatin nanocomposites were prepared using natural orange peel extract (OPE) in percentage of 7, 14, and 21% (v/v solution) and Cloisite 30B (5% w/w dry whey protein) made by a casting method. Mechanical, physical, and antibacterial properties of prepared films were measured as a function of OPE concentration. Higher concentrations of OPE led to higher antibacterial activity, tensile strength, and water solubility, but lower moisture content and transparency. The films microstructures were studied by field emission scanning electron microscopy (FESEM) and ATR-FTIR. Overall, the film containing 21%(v/v) OPE resulted in the best antibacterial, mechanical, and physical performance. Addition of tripolyphosphate (TPP) as a crosslinker to this sample led to the significant increase in transparency. Cloisite 30B, OPE, and TPP can therefore be used to improve the properties of WPI films as a promising natural food packaging.
A Co-culture Process with Pichia stipitis NCIM 3498 and Thermotolerant Saccharomyces cerevisiae VS 3 for Ethanol Production using Acid Hydrolysate of Delignified Sorghum Straw

Rising oil prices has attracted the research on bioconversion of lignocellulosic biomass to ethanol as an alternative fuel. Pretreatment of lignocellulosic biomass causes release of fermentable sugars both hexoses and pentoses. An efficient conversion of these two sugars is a prerequisite for a profitable process of bioethanol production from lignocellulose. Considering the approaches available for this conversion, co-culture is a simple process, employing two different organisms for the fermentation of the two sugars. The NaOH delignified sorghum straw released maximum amount of reducing sugars (30.0 g/l) in biphasic dilute acid hydrolysis. The microbial co-cultures of Pichia stipitis NCIM 3498 and thermotolerant Saccharomyces cerevisiae VS3 were employed for efficient bioconversion of mixed sugars present in the hydrolysate into ethanol. The fermentation of detoxified acid hydrolysate with monocultures of P. stipitis, S. cerevisiae VS3 and co-culture produced 10.25 ± 0, 7.40 ± 0.07, and 12.0 ± 0.55 g/L ethanol, respectively. _____________________________________________________________________________________________________________
Multicanonical Determination of the Symbol Error Ratio of WDM Polarization Multiplexed QPSK Systems

Abstract The multicanonical method is applied to the calculation of the symbol error ratio (SER) as a function of the optical signal to noise ratio (OSNR) at the receiver for a polarization multiplexed quadrature phase shift keying (PM-QPSK) wavelength division multiplexed (WDM) system. We improve upon previous calculations by including polarization mode dispersion (PMD) and subsequently verifying the numerical accuracy of our calculations. Our numerical studies demonstrate that acceptable accuracy can be achieved even when advancing the polarization through the fiber with relatively large propagation step lengths.
Optimal Linear Control of an Energy Harvesting System

This paper presents an optimal linear control of an energy harvesting system. Energy harvesting system models are typically non linear and therefore utilize a non linear controller. In this work, an investigation on the performance of a linear controller for a nonlinear harvester model is shown. The aim is to maximize the energy produced by implementing an optimal linear control algorithm. A mathematical model of the harvester is given. All simulations were conducted in matlab and simulink. Results obtained show that a current of 0.48mA and a voltage of 4.2Volts is harnessed. This study demonstrates that for local applications where transients and sensitivity to plant parameters is not a strong requirement, a linear controller can be utilized.
Exponential l 2 - l ∞ stochastic stability analysis for discrete-time switching Markov jump linear systems

The problem of exponential l 2 - l ∞ stochastic stability is considered in this paper for a class of discrete-time switching Markov jump linear systems(S-MJLS). Firstly, the definition of exponential l 2 - l ∞ stochastic stability is introduced. Then, by virtue of the average dwell time approach, the stochastic stability criteria are presented with an exponential l 2 - l ∞ performance index and a decay rate. A numerical example is provided to demonstrate the effectiveness of the obtained results.
Puerarin modulates autophagy to ameliorate cerebral ischemia/reperfusion injury through JNK signaling pathway

Puerarin, a major isoflavone in radix puerariae, exerts remarkable pharmacological effects on ischemic stroke patients in the clinic. However, the underlying mechanisms of the protective effects of puerarin are not fully elucidated. In this study, the effects of puerarin were explored on autophagy induced by cerebral ischemia/reperfusion injury (CIRI) through the c-Jun N-terminal kinase (JNK) signaling pathway. Male Sprague-Dawley (SD) rats were subjected to middle cerebral artery occlusion (MCAO) under deep anesthesia for 1.5 hours with subsequent 24 hour reperfusion. Neurological function deficits and infarct volume of brain tissue were assessed, and the expression of autophagy-related proteins was determined by Western blot with the ischemic cerebral penumbra cortex. The results demonstrate that puerarin alleviates cerebral infarct volume and neurological deficits when compared with I/R group. In addition, pre-treatment with puerarin notably decreased p-JNK-1/JNK-1, p-JNK-2/JNK-2, LC3-2/LC31, and expression of Beclin1, and significantly increased expression of Bcl2 and p62 when compared with the I/R group. Compared to the group pretreated with puerarin (100 mg/kg), p-JNK-1/JNK-1, p-JNK-2/JNK-2, LC3-2/LC3-1, Beclin1, and p62 levels had no significant differences in group pretreated with puerarin and SP600125. Moreover, pre-treatment with puerarin and SP600125 exerted similar effects as pre-treatment with puerarin when compared with the I/R group. These studies show that puerarin can attenuate autophagy in a dose-dependent manner and that SP600125 shows similar effects to puerarin. The mechanism is likely that puerarin can decrease expression of JNK and p-JNK, and then increase Bcl2 and interfere with the functions of Beclin1 during the execution of autophagy.
