Survey on XML encryption

Every transaction on the Internet involves some kind of data. Data can be transferred in various modes. Now a days, XML is widely used for transferring and storing the data. There must be some mechanism to protect these data. In most of the literature, two most important techniques i.e. XML Signature and XML Encryption are used for securing these XML data. These two techniques provide signing and encrypting of XML data using cryptographic functionalities and results are also represented in XML format. These two techniques are con- sidered as standard worldwide which is released by W3C. In this thesis we are focusing on XML Encryption. In this study, W3C standards are used to encrypt sensitive XML data. JavaScript has been used to implement encryption of XML data and "Node.js" as software platform for providing the environment for encrypting. In this study, time elapsed is also measured in case of encryption and decryption. We have used AES and Triple DES algorithm for encryption of XML data. For encryption of symmetric key, RSA is used. Library used is "xml-encryption" for encryption and decryption. Time analysis for encryption and decryption are also shown by graph

Managing Change and Strategic Thinking: Evidences from Hospitality and Tourism Sector of the UK

This qualitative paper examines the strategic thinking and managing change in complex business environment in the hospitality and tourism sector of the UK through the cases of Hilton London Canary Wharf and Hilton London Tower Bridge. For the purpose of analysis, researchers explored the research phenomenon under different models including TALC model and IBTEE Model. Using convenience sampling, researchers interviewed face-to-face 12 Line Managers and 30 employees through open-ended semi-structured interview questions regarding change management process and obstacles interlinked with it. Findings revealed that although Hilton hotels have adapted changes to some extent but there is still more room for further improvement. The management of the selected hotels highly relies on the training purpose for the effective change adaption whereas coaching and research is lagging behind. The biggest constraint during effective change adaption is the diverse background of the workforce as most are from the multicultural backgrounds. Moreover, the communication, ritual, and cultural barriers are causing issues in the change process. Lastly, the recommendations are given for consolidating effective change management at workplace

Understanding potential conflicts between human and non-human-primates: A large-scale survey in Malaysia

With increasing anthropogenic pressure, interactions between humans and wildlife may become more frequent, including conflictual ones. To reduce conflicts, it is important to understand how different factors (e.g. education, previous experience, demographic vari-ables) interplay with each other and contribute to the emergence of negative attitudes and behaviours toward wildlife in humans. To address this issue, we conducted a large-scale questionnaire in Malaysia, focusing on potential conflicts between human and other pri-mates. We used generalized linear mixed models to assess how formal education, knowl-edge about primates, negative experience and potential competition affected participants’ negative attitudes to primates (i.e. how humans perceive primates), their behavioural inten-tions (i.e. opinion on how to reduce conflicts) and behaviour (i.e. measures taken to reduce negative interactions). We found that negative experience and potential competition had a negative impact on participants’ attitude and behavior (i.e. primates were more likely perceived as filthy, as negatively affecting residents’ health and safety, and as an increas-ing problem, with participants more likely to use invasive methods, including captures). Both higher education and better knowledge of primates predicted more positive behav-ioural intentions (i.e. primates should be protected, non-invasive interventions should be used). Higher education, however, was also linked to more negative attitudes (i.e. primates negatively affect residents’ health and safety), and partly to negative behavior (e.g. use of invasive methods). In contrast, better knowledge about primates predicted positive behav-iour (i.e. exclusive use of non-invasive methods). Therefore, although better knowledge of primates had no clear effect on human attitudes, it may impact on their decisions to reduce potential conflicts with wildlife, and might be the most powerful tool to mitigate conflicts between humans and other specie

A Specific class of interneuron mediates inhibitory plasticity in the lateral amygdala

The lateral amygdala (LA) plays a key role in emotional learning and is the main site for sensory input into the amygdala. Within the LA, pyramidal neurons comprise the major cell population with plasticity of inputs to these neurons thought to underlie fear learning. Pyramidal neuron activity is tightly controlled by local interneurons, and GABAergic modulation strongly influences amygdala-dependent learning. Synaptic inputs to some interneurons in the LA can also undergo synaptic plasticity, but the identity of these cells and the mechanisms that underlie this plasticity are not known. Here we show that long-term potentiation (LTP) in LA interneurons is restricted to a specific type of interneuron that is defined by the lack of expression of synaptic NR2B subunits. We find that LTP is only present at cortical inputs to these cells and is initiated by calcium influx via calcium-permeable AMPA receptors. LTP is maintained by trafficking of GluR2-lacking AMPA receptors that require an interaction with SAP97 and the actin cytoskeleton. Our results define a novel population of interneurons in the LA that control principal neuron excitability by feed-forward inhibition of cortical origin. This selective enhanced inhibition may contribute to reducing the activity of principal neurons engaged during extinction of conditioned fear

Soil analysis gis-based fertility assessment and mapping of agricultural research station, Pakhribas, Dhankuta, Nepal

Soil fertility evaluation has been considered as a most effective tool for sustainable planning of a particular region. This study was conducted to determine the soil fertility status of the Agricultural Research Station, Pakhribas, Dhankuta, Nepal. The total 60 soil samples were collected randomly at a depth of 0-20 cm by using the soil sampling auger. For identification of soil sampling points A GPS device was used. The collected samples were analyzed for their texture, pH, OM, N, P2O5, K2O, Ca, Mg, S, B, Fe, Zn, Cu and Mn status following standard methods in the laboratory of Soil Science Division, Khumaltar. The Arc-GIS 10.1 software was used for soil fertility maps preparation. The observed data revealed that soil was dark yellowish brown (10YR 4/4) and yellowish brown (10YR 5/6) in colour, and single grained, granular and sub-angular blocky in structure. The sand, silt and clay content were 56.61±0.97%, 27.62±0.56% and 15.77±0.58%, respectively and categorized as loam, sandy loam and sandy clay loam in texture. The soil was very acidic in pH (4.66±0.07) and very low in available sulphur (0.53±0.11mg/kg), available boron (0.24±0.07mg/kg). The organic matter (1.34±0.07%), total nitrogen (0.09±0.003mg/kg), available calcium (605.70±31.40mg/kg), available magnesium (55.96±4.67mg/kg) and available zinc (0.54±0.22mg/kg) were low in status. Similarly, available potassium (115.98±9.19 mg/kg) and available copper (1.13±0.09 mg/kg) were medium in status. Furthermore, available manganese (36.31±2.82mg/kg) was high, whereas available phosphorus (105.07±9.89 mg/kg) and available iron (55.80±8.89 mg/kg) were very high in status. The soil fertility management practice should be adopted based on the determined status in the field for the sustainable production of crops. The future research strategy should be built based on the soil fertility status of the research farm

Genetic architecture and population structure of Oat Landraces (Avena sativa L.) using molecular and morphological descriptors

Oat is grown as winter forage in India. It is a self-pollinated crop with less variability. However, the variation fordifferent morphological traits in oat germplasm may be available at genotypic level. The present study was conducted tofind out the genetic diversity among 24 oat landraces using 9 morphological traits and 24 SSR primers. Morphological dataobserved across the 24 landraces showed wide variation and grouped various landraces into two clusters. GFY and DMYwere positively and significantly correlated with most of the traits studied. The molecular analysis using 24 SSR primersresulted amplification of 62 polymorphic alleles with an average of 2.58 alleles per primer. Size of amplified alleles rangedfrom 70 to 480 bp. Mean polymorphic information content was 0.42 showing moderate level of SSR polymorphism. Clusteranalysis based on SSR data differentiated 24 oat landraces into three major clusters. Bayesian model-based STRUCTUREanalysis assigned landraces into two clusters and showed the extent of admixture within individuals. Clustering pattern ofoat landraces based on SSR marker profiles were different from that of morphometric traits. So, based on the pooledanalysis at morphological and molecular level, the landraces IG-02-121, IG-02-129 and IG-02-113 were found superior formorphological traits as well as most distant among all the landraces under study. Hence, these landraces could be used in forfuture breeding programmes for genetic improvement in oats
