The cross-market dynamic effects of liquidity on volatility: evidence from Chinese stock index and futures markets

ABSTRACT This article investigates the cross-market asymmetric dynamic effects of liquidity on realized volatility and its intersection with jump volatility between Chinese stock index and futures market. The influence of index liquidity on futures market volatility is negative significantly after controlling for the long memory feature of realized volatility, and becomes much stronger for the after-crisis period. Liquidity of the futures market has a relative weak positive impact on stock volatility, and becomes insignificant after crisis. Our study reveals different influence mechanisms from the commonly known information transmission that new information is reflected in futures prices and volatility more quickly. The cross-market dynamic effects are time-varying and not influenced after controlling for jump volatility. Especially, index liquidity impacts positive jumps of both markets, while there is no impact of futures liquidity to index jump volatility.
Determinants of world business cycles: Some insights from a flexible dynamic factor model

Using a dynamic factor model, we characterize the business cycles co-movement among a panel of countries using a world factor, a country-speci(cid:133)c factor, and an idiosyncratic component. We allow correlated factors and then study the contribution of each type of factor to the business cycle dynamics. We (cid:133)nd that three world factors are necessary to characterize the co-movement on the world level. Our analysis shows that the three world factors correspond to the price dynamics, the consumption dynamics, and the GDP growth dynamics respectively. We then compare the importance of the world factor with that of the spill-over e⁄ects from the country-speci(cid:133)c factor. Then we study how these factors are related to country shocks as well as other economic variables. Our data set covers 23 countries, which include the G7, Four Little Dragons (except Taiwan), Four Little Tigers (except Indonesia), and large developing economies such as India and China, covering more than 75% of world total output.

A Sectoral Analysis of Foreign Direct Investment on the Economic Growth of Nepal

The role of foreign direct investment (FDI) on the economic growth is widely concerned in terms of increase in employment opportunities and for overall economic welfare, especially in developing nations like Nepal. On this context, this paper makes an attempt to examine the sector wise effects of FDI uneconomic growth in Nepal represented by gross domestic product (GDP) and FDI as dependent and independent variables respectively, thereby identifying the direct effect of FDI on GDP using 10 years (2007 to 2016) sect oral data as main source of the information. The entire result of the inferential analysis predicts that FDI of industry, tourism and agriculture sectors have a very positive and significant impact on GDP during the stipulated timeframe. In this line, findings suggest that the main stakeholders and government have to come up with new policy to open up foreign investment in other sectors as well which helps to move informal activities into formal economy. Finally, it is noted that formulation of new plan and policy will be a necessary condition but nonsufficient step for the development, so the key recommendations are made for the effective steps and actions to be taken by the concerned authority to review and implement the introduced plan and policies, which in turn, will help in flow of FDI to achieve, accelerate, and sustain the high rate of economic growth in Nepal.

Entrepreneurship plays a significant role in socio-economic growth of a country and is a major concern to both scholars and policy makers. Within entrepreneurial ecosystem, women entrepreneurs are also regarded as new growth engine of socio-economic development. Therefore, based on liberal feminist theory the present study intends to examine those factors that affect the growth of women entrepreneurs in Pakistan. The study adopts qualitative research design and data was collected through semi-structured interviews from sample of fifteen women entrepreneurs, who work behind the veil due to different issues in Rawalpindi, Punjab Pakistan. The interviews were content analyzed. The result of content analysis reveal that socio-cultural, education, experience, personal, and financial factors influence the growth of women entrepreneurs in Pakistan. The findings of this study have clear implications for policy makers in making policies to address women's entrepreneurial issues.
Citizens’ involvement in emergency preparedness and response: a comparative analysis of media strategies and online presence in Turkey, Italy and Germany

This article reviews the role that citizens may play as first responders by comparing how various communication media are utilized by response organizations and government agencies to train and network with citizens. In addition, it aims to investigate the nature of the communication strategies and approaches that are utilized by organizations reaching out to volunteers. In order to accomplish this goal, we engaged in an analysis of citizen awareness programmes and volunteer training processes in three different countries: Turkey, Italy and Germany. Across the analysed countries, we observed inconsistencies in the extent and types of utilization of social media, including the fact that the dominant approach is still communicat- ing to citizens rather than communicating with citizens. Finally, the comparative analysis points out the inconsistent accessibility or availability of training materials online, and particularly in social media platforms. This may reduce the likelihood that a large portion of the population, mostly of younger age, will have the opportunity to stay informed on important emergency preparedness topics.

Optimization of Just-In-Sequence Supply: A Flower Pollination Algorithm-Based Approach

The just-in-sequence inventory strategy, as an important part of the supply chain solutions in the automotive industry, is based on feedback information from the manufacturer. The performance, reliability, availability and cost efficiency are based on the parameters of the members of the supply chain process. To increase the return on assets (ROA) of the manufacturer, the optimization of the supply process is unavoidable. Within the frame of this paper, the authors describe a flower pollination algorithm-based heuristic optimization model of just-in-sequence supply focusing on sustainability aspects, including fuel consumption and emission. After a systematic literature review, this paper introduces a mathematical model of just-in-sequence supply, including assignment and scheduling problems. The objective of the model is to determine the optimal assignment and schedule for each sequence to minimize the total purchasing cost, which allows improving cost efficiency while sustainability aspects are taken into consideration. Next, a flower pollination algorithm-based heuristic is described, whose performance is validated with different benchmark functions. The scenario analysis validates the model and evaluates its performance to increase cost-efficiency in just-in-sequence solutions.
INTERGENERATIONAL MOBILITY: EARNINGS AND EDUCATION IN ISRAEL

Matched census data for 1983 and 1995 are used to estimate the intergenerational correlation and mobility coefficients between the earnings and educational attainments of parents and their adult children. I also calculate changes in intergenerational inequality in these variables. Intergenerational β-convergence is decomposed into mobility, Giniconvergence, and leveling (up and down) effects. Sibling earnings and educational attainments are compared to estimate family background effects. In addition to standard measures of all the estimated parameters, I report permanent measures, which net out transitory components in earnings mobility. Current earnings in Israel are more intergenerationally mobile than in other countries. However, the intergenerational mobility of permanent earnings is similar to abroad. Finally, intergenerational earnings mobility is greater among Sephardim and Non-Jews, and it varies inversely with parents’ education and “Israeliness”, as measured by the number of generations that the family has been in Israel.

From The Field: Can Our Service Change Us? Bringing the Classroom to Service Learning in the Southern African Kingdom of Lesotho

Based on a decade’s worth of service-learning trips to Lesotho, this paper focuses on the role of nightly discussion sessions in achieving our learning goals. It also examines how we carried out our community-service projects in conjunction with class material to help students move past negative stereotypes and objectification of the Basotho (an ethnic group whose ancestors have lived in southern Africa since around the fifth century) toward a greater understanding of the Basotho as people. During our community service, students often expressed feelings of pity for the Basotho as well as a sense of frustration at why they do not do more to help themselves. This paper will also address how the trip helps students move from feelings of pity to that of empathy, as well as creating an environment that helps break down the barriers between those performing community service and the communities they are working with.
Antarctic governance in a climate changed world

ABSTRACT The Antarctic Treaty System (ATS) is regarded as one of the more successful cases of international governance. For nearly 60 years, the ATS has provided the basis for peaceful use of the Antarctica and facilitated international cooperation on scientific research on the continent. The ATS now faces several new challenges largely driven by global environmental change from human activities carried out outside the region. Most prominently, human-induced climate change is impacting the Antarctic cryosphere and marine ecosystems of the Southern Ocean and increasing the scope of human activities in these areas. A key challenge for Antarctic governance will be managing regime interaction between the ATS and the growing number of environmental, resource management and wider regimes operating in the region. Given this institutional complexity, we argue that the concept of an ‘Antarctic regime complex' provides useful insights for understanding interaction between the ATS and other institutions operating within the region. Finally, we conclude that the ATS will likely require a new level of institutional resilience in interacting other regimes within the Antarctic regime complex, as it continues to perform a key role in shaping governance of the region.
Effect of dietary garlic and thyme seed supplementation on the production performance, carcass yield and gut microbial population of broiler chickens

Abstract This experiment was conducted to evaluate the effect of dietary garlic and thyme seed supplementation on the production performance, carcass yield and gut microbial population of broiler chickens. A total of 200 Cobb 500 male broilers were randomly allocated to 4 treatments consisting of 5 replications with 10 chicks each. Treatments were control diet (T1), control diet with 1% thyme seed powder (T2), control diet with 1% garlic powder (T3) and control diet with 0.5% thyme seed and 0.5% garlic powder (T4). Feed intake, body weight, weight gain, feed conversion ratio (FCR), carcass yield were not significantly (p>0.05) improved by dietary treatments compared to control. Escherichia coli (E. coli) count in the gut of broilers did not show significant difference among dietary treatments. However, lactobacilli count in the gut of broilers significantly (p 0.05) with each other. It was concluded that thyme seed was reliable as feed additive in the broiler diet and could provide positive advantages to the colonization and proliferation of lactobacilli.
A ROAD TOWARDS A BETTER WRITING

Writing is used as primary activity within most of the master programs within Civil Engineering education to support the students to reach a significant number of learning outcomes in different courses. However, none of these activities address writing itself even less how it must be performed, so it is a demand to the students to write and critically review technical reports in many occasions without giving proper tools on how to do it. That has raised some concerns among teachers involved in the program. A more generalized problem that affects students across the entire master program is that many of them reach the final master thesis report with clear writing difficulties. In this paper, therefore, it is present a proposal on how to address the writing by introducing new Teaching/Learning Activities (TLAs), Intended Learning Outcomes (ILOs) and Assessment Activities (AAs) transversally through the master program. Consequently, some courses within the MPSEB has been selected and modified accordingly.
A SOPC Architecture for Data-dependent Superimposed Training Channel Estimation

Channel estimation in wireless communication systems is usually accomplished by inserting, along with the information, a series of known symbols, whose analysis is used to define the parameters used by filters that remove the distortion of the data. Nevertheless, a part of the available bandwidth has to be used by these symbols. Until now, no alternative solution has demonstrated to be fully satisfying for commercial use, but one technique that looks promising is superimposed training (ST). This work describes a hybrid softwarehardware FPGA implementation of a recent algorithm that belongs to the ST family, known as Data-dependent Superimposed Training (DDST), which does not need extra bandwidth for its training sequences (TS) as it adds them arithmetically to the data. DDST also adds a third sequence known as data-dependent sequence, that destroys the interference caused by the data over the TS. As DDST’s computational burden is to high for the commercial processors used in mobile systems, a SOPC (System on a Programmable Chip) approach is used in order to solve the problem.
DorkPot : A Honeypot-based Analysis of Google Dorks

Attackers use search engines to find vulnerable systems and interesting information such as passwords, hidden files, or other kinds of sensitive information on the Internet. Besides common search terms, they use advanced search parameters called Google dorks to find only results with specific strings in the URL or files with a particular extension. So far, only a few works have empirically studied Google dorks, e.g., if they are still in use, which Google dorks attackers use, and how often as well as how old the used Google dorks are. In this paper, we study this type of attacks from a different perspective and present DorkPot, a dynamic, low-interaction webserver honeypot to detect Google dork related requests and, thereby, analyze such attacks in the wild. DorkPot uses Google dorks as input and creates a website for each Google dork, which matches the Google dork’s content, e.g., strings in the title field or the URL. Hence, we ensure the particular website can be found later via a Google search with the corresponding Google dork. To evaluate our prototype implementation, we deployed DorkPot with more than 4,000 Google dorks as input on ten instances of a cloud provider. Throughout more than ten months, we collected almost 9,000 clicks for 371 different Google dorks. Our analysis reveals that the top-ten Google dorks were responsible for more than 50% of the clicks, were mostly published in mid-2017 and searched for various online devices, such as IP cameras or routers, as well as passwords and database backups. In particular, three of the top-ten Google dorks targeted Internet of Things devices and another two searched for passwords and related files with authentication information.
Recent Glacier Recession in California

The aim of this study is to analyze the spatial patterns of glacier wastage in California. Detailed annual observations have been carried out over perennial ice masses of the Mt. Shasta and Sierra Nevada. We use digital elevation models of different regional glaciers generated from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) between 2002 and 2015. The results demonstrate that the ice masses have been significantly receded throughout the period. The overall mass balance trends in Mt. Shasta and Sierra Nevada mountain ranges were –5.20 ±7.37 m w.e. yr-1 and –8.09 ±4.02 m w.e. yr-1 respectively between 2002 and 2014-15. Most of the glaciers in the region had significant thinning rates. An elevation difference of -64.2 ±0.65 m on ice mass observed in the Mt. Mendel in Sierra Nevada. Also, extreme areal loss of perennial ice masses of about 87% between 2000 and 2014-15 was observed in Mt Shasta and Sierra Nevada. Considering the current water crises in California, our study provides valuable insights into the possible role of climatic factors on the glacier recession in the region.
Exploration of test methodologies to detect weak bits in SRAMs

Embedded memories will continue to dominate the System-on-Chip (SoC) area in subsequent years. SRAMs are designed to exploit the technology limits to achieve highest storage capacity, minimum access times and operating voltages. Consequently SRAMs are prone to manufacturing losses. In advanced technology nodes, process limitations and device variations limit the SRAM performance and yield. Intra-die mismatches, process shifts, random variations in device parameters such as Threshold Voltage (V t ) and effective channel length and other defects are inevitable. The increased process spreads of modern scaled down technologies can compromise the stability of SRAM cells. All these result in the increase in probability of SRAM cells becoming weak for such highly dense memories. The performance parameters, majorly cell stability, and other Figures of Merit (FOMs) of a weak cell get deteriorated which lead to reliability issues in the SRAM. A weak cell might accidentally flip its contents during some worst case operating conditions. However, memories designed in state-of-the-art technologies like Fully Depleted Silicon on Insulator (FDSOI) possess several performance benefits due to dopant free channel, but the impact of process variations, resistive defects, transistor mismatches, IR drops and coupling still exist in SRAM core causing cell weakness. To ensure reliability of SRAMs, it is important to identify such weak cells post silicon. In this work, a comprehensive analysis on the weak cells and their effect on various FOMs have been conducted. Based on the limitations of the existing stability fault detection techniques, techniques for the identification of weak cells in SRAMs have been explored. Here, correlation based test methodologies for the efficient detection of weak bits in SRAMs have been proposed. The proposed methodology targets high speed testing at lower test costs. It enables to perform the test at nominal operating voltage and room temperature. For verification of the test methodologies, case study is conducted for a single port SRAM instance in 28nm FDSOI technology. The work presented in this thesis is carried out at ST Microelectronics.
Socio-economic status and participation in higher education : Do costs matter ?

We study the impact of socio-economic status on study decisions in higher education. Students from socially disadvantaged backgrounds participate less in higher education because they accumulate less human capital during high school, have lower preferences for education and are more sensitive to costs. We use a discrete choice approach to distinguish between these e¤ects and compare the results of a conditional logit model, a nested logit model and a mixed logit model. We apply our analysis to Flanders where tuition fees are low and all high school graduates have access to higher education. We demonstrate that the long term e¤ects of socio-economic status, such as preferences for education and high school outcomes, dominate the cost e¤ect. We then simulate the e¤ect of additional scholarships in higher education. Although the cost e¤ect of socio-economic status is small compared to the long term e¤ects, we still nd stronger e¤ects of scholarships on the participation of students from disadvantaged backgrounds.
