An Approach to Reduce Cloud Spot Instances Cost

: The cost reduction is one of the attractive features offered by the cloud. Spot leasing is one way to reduce the cost. Spot leasing is done by leasing the unused excess instances with low price. On the other hand, spot instances are facing risks that minimize their reliability and desirability. Risks including instances reclaiming and dynamic price changing. Minimizing the risks associated with the spot leasing is going to help to increase the utilization of the spot instances, which in turn is going to attract more users. In this paper, a framework has been proposed to mitigate the instances reclaiming risk while reducing the leasing cost as possible. This is done by monitoring many markets and hopping between instances. The proposed framework has been evaluated through simulating using randomly generated data and actual data collected from Amazon web services. The proposed framework recorded 9% to 42% of cost reduction compared with the actual cost.
Longevity, Life-Cycle Behavior and Pension Reform

How can public pension systems be reformed to ensure fiscal stability in the face of increasing life expectancy? To address this question, we use micro data to estimate a structural life-cycle model of individuals’ employment, retirement and consumption decisions. We calculate that, in the case of Germany, an increase of 3.76 years in the pension age thresholds or a cut of 26.8% in the per-year value of public pension benefits would offset the fiscal consequences of the increase in life expectancy anticipated to occur over the next 40 years. On average, individuals value the increase in the pension age thresholds at 3.44% of baseline consumption, and are willing to forgo 8.51% of baseline consumption to avoid the cut in per-year pension value. The increase in the pension age thresholds makes 87.7% of individuals better-off, and generates large responses in labor supply and retirement behavior. However, the favorable effects of this reform depend on the availability of jobs for older individuals.
Low‐carbon energy policy analysis based on power energy system modeling

The effect of carbon policies and mechanisms on the behavior of market participants and market equilibrium has been increasingly recognized, of which tax incidence is one of these important issues. Tax incidence is the market output of both producers and consumers that respond to taxes with market equilibrium, whether the tax is levied on sellers or buyers. This paper aims to study the carbon tax incidence on the transmission level of a power system based on different carbon tax collection methods in electricity market environment. A statistical demand elasticity model, power ﬂow and carbon emission ﬂow models are applied to simulate the electricity market equilibrium to analyze the effects of the tax levied on demand-side or supply-side. Furthermore, the Australian 59-bus system is employed in the case study with four stages and four main cases. The results demon-strate that consumers share more burden of the carbon tax in all carbon tax collection methods. Moreover, the proportion of the tax burden and emission reduction effect are different in each method and degree of renewable energy capacity. The results of this paper contribute to the establishment of emission-related energy policies toward a low-carbon economy.
Advanced characterisation of aerosol size properties from measurements of spectral optical depth using the GRASP algorithm

This study evaluates the potential of using aerosol optical depth (τa) measurements to characterise the microphysical and optical properties of atmospheric aerosols. With this aim, we used the recently developed GRASP (Generalized Retrieval of Aerosol and Surface Properties) code for numerical testing of six different aerosol models with different aerosol loads. The direct numerical simulations (self-consistency tests) indicate that the GRASP-AOD retrieval provides modal aerosol optical depths (fine and coarse) to within 0.01 of the input values. The retrieval of the fine-mode radius, width and volume concentration are stable and precise if the real part of the refractive index is known. The coarse-mode properties are less accurate, but they are significantly improved when additional a priori information is available. The tests with random simulated errors show that the uncertainty in the bimodal log-normal size distribution parameters increases as the aerosol load decreases. Similarly, the reduction in the spectral range diminishes the stability of the retrieved parameters. In addition to these numerical studies, we used optical depth observations at eight AERONET locations to validate our results with the standard AERONET inversion products. We found that bimodal log-normal size distributions serve as useful input assumptions, especially when the measurements have inadequate spectral coverage and/or limited accuracy, such as moon photometry. Comparisons of the mode median radii between GRASP-AOD and AERONET indicate average differences of 0.013 μm for the fine mode and typical values of 0.2–0.3 μm for the coarse mode. The dominant mode (i.e. fine or coarse) indicates a 10 % difference in mode radii between the GRASP-AOD and AERONET inversions, and the average of the difference in volume concentration is around 17 % for both modes. The retrieved values of the fine-mode τa(500) using GRASP-AOD are generally between those values obtained by the standard AERONET inversion and the values obtained by the AERONET spectral deconvolution algorithm (SDA), with differences typically lower than 0.02 between GRASP-AOD and both algorithms. Finally, we present some examples of application of GRASP-AOD inversion using moon photometry and the airborne PLASMA sun photometer during the ChArMEx summer 2013 campaign in the western Mediterranean.
Phylogenetic and functional adaption of the gastrointestinal microbiome of goats kept at high altitude (4800 m) under intensive or extensive rearing conditions

Background: The gut microbiota composition is influenced by the diet as well as the environment in both wild and domestic animals. Although the rumen microbiome in herbivorous ruminants has been studied intensively, there is a lack of data regarding the simultaneous adaption of the rumen and hindgut metagenome as affected by different feeding systems in extreme environments. Therefore, we studied the effects of two feeding systems, grazing and drylot, on the rumen and hindgut microbiome composition of semi-feral Tibetan goats kept at high altitude (~4800 m). 16S rRNA gene sequencing and metagenomic analysis were conducted on DNA extracts from the contents and mucosal layer of different sections of the gastrointestinal tract (rumen, cecum, and colon). Results: Intensive drylot feeding resulted in significantly higher zootechnical performance, narrower ruminal acetate: propionate ratios and a drop in the average rumen pH at slaughter to ~5.04. In response, the ruminal microbiome of drylot goats expressed a significantly lower diversity compared to the grazing animals. Otherwise, hindgut microbial adaption appeared to more diverse in the drylot group suggesting a higher influx of undegraded complex non-starch polysaccharides from the rumen. Despite their higher fiber levels in the diet, grazing goats exhibited lower counts of Methanobrevibacter and genes associated with the hydrogenotrophic methanogenesis pathway, presumably reflecting the scarce dietary conditions (low energy density) when rearing goats on pasture from extreme alpine environments. These conditions appeared to promote a relevant abundance of bacitracin genes, which potentially benefits the host's adaption to harsh environmental conditions. In parallel, we recognized a significant increase in the abundance of antibiotic resistance genes in the digestive tracts of drylot animals.Conclusion: In summary, this study provides a deeper insight in the phylogenetic and functional adaption of the gastrointestinal microbiome of goats subject to intensive drylot and extensive pasture rearing conditions at high altitude.
Corporate governance and quality of financial statements: a study of listed Nigerian banks

This study investigated the influence of Corporate governance on the timeliness of financial reports of listed banks in Nigeria. In order to provide answers to the research questions raised in this study, data were generated from the annual report of the listed banks on the Nigerian Stock Exchange considering the period 2008–2015. The study used Board size, Board Independence and Foreign Executives on the board as proxies for corporate governance. The data were analyzed using descriptive statistics, correlation matrix and panel data regression analysis. It was observed that board size had a non-significant negative relationship with the timeliness of financial reports. Also, the study observed that board independence also had a non-significant negative relationship with the timeliness of financial reports. Finally, it was observed that foreign executives on the board had a significant positive relationship with the timeliness of financial reports. The study thus recommends that the existing legal framework in Nigeria should be developed that clearly specifies the rights and obligations of a bank, its management and, of course, other stakeholders.

Acculturation and adaptation issues among International students: Experiences from the largest Public University of Bangladesh

This qualitative study surfaces the kinds of acculturation and adaptation related problems that international students faced while they studied at the largest public university in Bangladesh. Qualitative data was collected and analyzed through face-to-face interviews with 82 international students. Findings show that in terms of acculturation, students faced homesickness, language barriers, socio-cultural issues and academic reactions to their new life. In terms of adaptation related issues, students faced psychological distress, practical issues like financial constraints, perceived discrimination and social exclusion. Considering these findings, it can be inferred that host language, social engagement, academic environment and hostel life play an important role in the acculturation experiences of international students. This study highlights the importance of host language in determining the friendships and overall adaptation of the international students.
Safety and Health Issues in Selected Schools of Chibombo District in Central Province of Zambia

Safety and health management in schools is a growing concern in Zambia. Media reports on dilapidated infrastructure, unhealthy conditions and other cases of insecurity in schools have been on the rise. According to United Nations Children’s Fund (UNICEF, 2009) academic attainment is regarded as a decisive factor that determines educational quality. Therefore, in pursuing such academic attainment, children have the right to learn in a safe and healthy environment. With reference to the argument by UNICEF, this paper explored safety and health issues in selected schools of Chibombo District in Central province of Zambia. Using purposive and simple random sampling, a sample of fifty stakeholders in randomly selected schools of Chibombo district was selected. This sample comprised teachers, pupils and auxiliary staff in the selected schools. Data was collected using unstructured interviews and focus group discussion. Data collected was analyzed using descriptive statistics and thematic analysis. This paper established that the selected schools faced many safety and health challenges. This study established that as much as the selected schools in Chibombo district had put in place safety and health measures, there were still outstanding safety and health concerns. It is therefore recommended that the government should provide safe and health school environments through appropriate frameworks, guidance and legislation.
Initial development of watermelon in fuction of substrates and irrigation with saline water

We evaluated the initial development of watermelon cv. Crimson Sweet seedlings grown in different organic substrates and electrical conductivity of irrigation water. The experiment was carried out in a greenhouse between January and March of 2017. The experimental design was in randomized blocks with factorial arrangement 3 x 5. The treatments were combinations of three substrates: soil + bovine manure (SBM) (1:1); soil + sheep manure (SSM) (1:1) and commercial substrate Basaplant ® (CS), and five electrical conductivity of irrigation water (EC iw ): C1 – 0.3 dS m -1 ; C2 – 1.5 dS m -1 ; C3 – 2.7 dS m -1 ; C4 – 3.9 dS m -1 and C5 – 5.1 dS m -1 . Plant height, number of leaves, stem diameter, root fresh mass, stem fresh mass, leaf fresh mass, root dry mass, stem dry mass, and leaf dry mass were evaluated at 37 days after sowing (DAS). The interaction between substrate x EC iw significantly affected the variables plant height, number of leaves, stem fresh mass and leaf fresh mass; all the analyzed variables were affected by substrate factor, while plant height, number of leaves, root dry mass, stem dry mass, and leaf dry mass were affected by EC iw . It is possible to produce watermelon cv. Crimson Sweet seedlings using water with electrical conductivity up to 2.86 dS m -1 associated with commercial substrate and up to 2.67 dS m -1 associated with sheep manure. It can be inferred that the use of commercial substrate is more suitable for the production of watermelon cv. Crimson Sweet seedlings.
Make me Happy: Usability, Mindfulness and Acceptance of the Intervention Geluk en Zo

Acceptance and Commitment Therapy (ACT) is seen as an alternative approach for pain treatment, focusing on the promotion of overall well-being, not a reduction of pain. The present article evaluated the usability and effectiveness of a short term self help intervention based on ACT, named ‚Geluk en Zo‘. A total of 18 participants from the dutch population completed questionnaires over the concepts of mindfulness and acceptance at prior and after the intervention. In addition, interviews over the perceived usability were held, as the intervention is currently under development. No clinical relevant improvements on both concepts mindfulness and acceptance were found. In contrast, reported user experiences were promising; the intervention was regarded as positive and effective by the participants. Further more, participants provided constructive feedback and essential suggestions for the further development of the intervention. Given these findings, Geluk en Zo seems to have potential in the prevention of mental illness or treatment of pain.
Family Seiberg-Witten invariants and wall crossing formulas

In this paper we set up the family Seiberg-Witten theory. It can be applied to the counting of nodal pseudo-holomorphic curves in a symplectic 4-manifold (especially a Kahler surface). A new feature in this theory is that the chamber structure plays a more prominent role. We derive some wall crossing formulas measuring how the family Seiberg-Witten invariants change from one chamber to another.
Corporate governance, market competition and investment decisions in Mexican manufacturing firms

We study how competition and corporate governance may explain investment decisions of Mexican manufacturing firms. We develop the study with indexes of market concentration and agency costs and OLS regressions. The analysis uses longitudinal census data. Our results suggest that investment is better explained by the Dominance Index, a Mexican measure of concentration, than by the Herfindahl-Hirschman one. They also suggest that agency costs (proxy for the degree of separation of ownership and control), and market competition may encourage investment decisions. Furthermore they suggest an inverse relationship between market competition and agency costs. We believe that our findings support the hypothesis that competition may be an alternative mechanism to encourage corporate practices in emerging economies.

’ s repository of research publications and other research outputs Sentiment Analysis in Social Streams Book Section

In this chapter we review and discuss the state of the art on sentiment analysis in social streams –such as web forums, micro-blogging systems, and social networks–, aiming to clarify how user opinions, affective states, and intended emotional effects are extracted from user generated content, how they are modeled, and how they could be finally exploited. We explain why sentiment analysis tasks are more difficult for social streams than for other textual sources, and entail going beyond classic text-based opinion mining techniques. We show, for example, that social streams may use vocabularies and expressions that exist outside the mainstream of standard, formal languages, and may reflect complex dynamics in the opinions and sentiments expressed by individuals and communities.
Analysis of on farm conservation of sweet corn in a diversity microcenter of Zea mays L. in Southern Brazil

Corn has a great diversity of types and races, being cultivated all around the world. In Brazil, corn is one of the main commodities, being produced practically by every rural family. In the Far West region of the Santa Catarina state, Southern Brazil, corn has several purposes that vary according to the type of grain. In the case of sweet corn, the grains are basically used for the family's own consumption. This study aimed at identifying the diversity of sweet corn in the region and analyzing the diversity indicators and the factors associated with in situ on farm conservation and genetic erosion. Therefore, a Diversity Diagnosis was performed through semi-structured interviews with 31 maintainers of corn previously indicated as sweeter. Thirty-one varieties were identified, among which twenty-one were classified as sweet corn of wrinkled kernels and ten as sweet corn of dent kernels. The varieties have been conserved on average for 8.8 years, and the main reason for conservation was self consumption of the grains as fresh corn. The main reasons for seed loss, according to the farmers, were the occurrence of drought and the non-multiplication of seeds by the family. The diversity microcenter of Zea mays L. in Southern Brazil hosts local sweet varieties of wrinkled and dent kernels under in situ on farm conservation, with agronomic, adaptive and market potential for in natura or canned consumption. However, such diversity is at risk of genetic erosion, and therefore strategies are presented to mitigate the impacts on this local germplasm.
Endohedral terthiophene in zigzag carbon nanotubes: Density functional calculations

The inclusion and encapsulation of terthiophene T3 molecules inside zigzag single-walled carbon nanotubes CNT’s is addressed by density functional calculations. We consider the T3 molecule inside six semiconducting CNT’s with diameters ranging approximately from 8 to 13 A. Our results show that the T3 inclusion process is exothermic for CNT’s with diameters larger than 9 A. The highest energy gain is found to be of 2 eV, decreasing as the CNT diameter increases. This notable effect of stabilization is attributed to the positively charged CNT inner space, as induced by its curvature, which is able to accommodate the neutral T3 molecule. The band structure of the T3@CNT system shows that T3 preserves its electronic identity inside the CNT’s, superimposing their molecular orbitals onto the empty CNT band structure without hybridization. Our results predict that the electronic states added by the T3 molecules would give rise to optical effects and nonradiative relaxation from excited states.
General solutions for plane extensible elasticae having nonlinear stress-strain laws

A general finite deformation solution is obtained for the equilibrium of hydrostatically loaded elasticae whose underformed shapes are circular arcs. The nonlinear stress-strain relations employed give the bending moment and the axial force as derivatives of a strain energy function with respect to suitable strain measures. The representation of the solution involves arbitrary constants of integration which can accommodate any end conditions consistent with equilibrium. Examples are given. The constraint of inextensibility is examined and a perturbation procedure for small extension is developed. In an appendix, the stress-strain laws are derived by an appropriate reduction of the equations for three-dimensional hyperelasticity.
