The Impact of Energy Markets on the EU Agricultural Sector
No full textThe objective of this study is to analyze the impact of crude oil prices on the EU-27 agricultural sector in an era when the biofuels sector is expanding because of the policy initiatives taken by the EU Commission and member states. To this end, first a baseline is set up for the EU-27 ethanol, grain, and dried distillers grains markets. In the next step, two different scenarios are run. The first scenario incorporates a $10- per-barrel increase in the EU-27 crude oil price with the ethanol import tariffs in place. The second scenario incorporates the same shock with the ethanol import tariffs removed. In the first scenario, higher crude oil prices increase ethanol consumption, production, and therefore grain prices. In the second scenario, the impact of trade liberalisation is larger than the impact of the higher crude oil price. So, grain prices decline in this scenario despite an expansion in ethanol consumption. If there were a high enough crude oil price shock, which would affect the EU-27 ethanol market more than trade liberalisation, the net impact on grain, feed, and food prices from the crude oil price shock would be mitigated by the increased trade from trade liberalisation. The study shows that the impact of energy prices on the EU-27 agricultural sector is increasing with the emergence of the biofuels sector. It also illustrates the importance of trade policy in responding to higher crude oil and grain prices.Ethanol, energy prices, trade liberalisation, Resource /Energy Economics and Policy,

Effect of Landscape Composition and Invasive Plants on Pollination Networks of Smallholder Orchards in Northeastern Thailand
No full textDestruction of natural habitat, land-use changes and biological invasion are some of the major threats to biodiversity. Both habitat alteration and biological invasions can have impacts on pollinator communities and pollination network structures. This study aims to examine the effect of an invasive plant, praxelis (Praxelis clematidea; Asteraceae), and land-use types on pollinator communities and the structure of pollination networks. We conducted the study in smallholder orchards which are either invaded or non-invaded by P. clematidea. We estimated the pollinator richness, visitation rates, and pollinator diversity and evaluated the network structures from 18 smallholder orchards in Northeastern Thailand. The effect of landscape structure in the vicinity of the orchards was investigated, with the proportion of agricultural, forest, and urban landscape within a 3 km radius analyzed. The invasive species and land-use disturbance influence the pollinator communities and pollination network structure at species level was affected by the presence of P. clematidea. Bees were the most important pollinator group for pollinator communities and pollination networks of both invaded or non-invaded plots, as bees are a generalist species, they provide the coherence of both the network and its own module. The urban landscape had a strong negative influence on pollinator richness, while the proportions of agriculture and forest landscape positively affected the pollinator community

On the Effect of Clock Frequency on Voltage and Electromagnetic Fault Injection
No full textWe investigate the influence of clock frequency on the success rate of a fault injection attack. In particular, we examine the success rate of voltage and electromagnetic fault attacks for varying clock frequencies. Using three different tests that cover different components of a System-on-Chip, we perform fault injection while its CPU operates at different clock frequencies. Our results show that the attack’s success rate increases with an increase in clock frequency for both voltage and EM fault injection attacks. As the technology advances push the clock frequency further, these results can help assess the impact of fault injection attacks more accurately and develop appropriate countermeasures to address them.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Cyber Securit
Deep Learning-Based Side-Channel Analysis Against AES Inner Rounds
No full textSide-channel attacks (SCA) focus on vulnerabilities caused by insecure implementations and exploit them to deduce useful information about the data being processed or the data itself through leakages obtained from the device. There have been many studies exploiting these leakages, and most of the state-of-the-art attacks have been shown to work on AES implementations. The methodology is usually based on exploiting leakages for the outer rounds, i.e., the first and the last round. In some cases, due to partial countermeasures or the nature of the device itself, it might not be possible to attack the outer rounds. In this case, the attacker needs to resort to attacking the inner rounds. This work provides a generalization for inner round side-channel attacks on AES and experimentally validates it with non-profiled and profiled attacks. We formulate the computation of the hypothesis values of any byte in the intermediate rounds. The more inner the AES round is, the higher is the attack complexity in terms of the number of bits to be guessed for the hypothesis. We discuss the main limitations for obtaining predictions in inner rounds and, in particular, we compare the performance of Correlation Power Analysis (CPA) against deep learning-based profiled side-channel attacks (DL-SCA). We show that because trained deep learning models require fewer traces in the attack phase, they also have fewer complexity limitations to attack inner AES rounds than non-profiled attacks such as CPA. This paper is the first to propose deep learning-based profiled attacks on inner rounds of AES to the best of our knowledge.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Cyber Securit
Prediction of satisfaction indicators increasing the level of happiness: evidence from the Turkish life satisfaction survey
No full textResearch on happiness, in the meaning of the ultimate goal of people’s lives, dates back to ancient times. Living well and creating suitable conditions to achieve happiness are essential issues in one’s life. However, happiness is affected by many factors. The first thing that comes to mind is the psychological ones. Besides, many socio-economic satisfaction indicators and demographic profiles have an effect on establishing a happy environment. In this line, this paper aims to examine the relationship between the level of happiness and satisfaction indicators by employing multiple linear regression modelling to data from the 2019 Turkish Life Satisfaction Survey. The regression results reveal that the satisfaction indicators considered in this study, except satisfaction from education, significantly explain the happiness level. Admittedly, an increase in educational attainment also improves the level of happiness, however, educational attainment may be a source of unhappiness for especially Turkish people who are disappointed in working life. © 2022, The Author(s), under exclusive licence to Springer Nature B.V
Going global: The role of gatekeepers in the transnational reception of defne suman’s the silence of scheherazade
No full textGoing Global: The Role of Gatekeepers in the Transnational Reception of Defne Suman’s The Silence of ScheherazadeOn August 12, 2021, with hashtags, #historicalfiction, #translatedfiction, #greece, #turkey, #armenia, #levant #empire, #Scheherazade, Defne Suman announced the release of her English-language debut novel, The Silence of Scheherazade on social media. The novel centres on the tale of the burning of Smyrna in 1922, told through Levantine, Greek, Turkish and Armenian inhabitants of the city. Her gatekeepers, Head of Zeus Independent Publishing Company, the book’s translator Betsy Göksel and her literary agent Nermin Mollaoğlu were among the first ones to receive tribute for their hard work and support in the process. In the following months, Maureen Freely hosted the book’s launch in an online event, organized by Powell’s Books in Portland, Oregon. Succeeding interviews, book reading events and podcasts concentrated on the writer’s upbringing, other authors who influenced the style of the author, the translation process, the role of history in the book, as well as the motivation behind its title, which was different from its Turkish version, Emanet Zaman (2016).If World Literature is constituted by \"literary works that circulate beyond their culture of origin, either in translation or in their original language,\" as Damrosch (2003: 4) states, then, other actors who are involved in the work’s interaction with the world audience pave the way for its success in the global market, as William Marling claims in Gatekeepers: The Emergence of World Literature in the 1960s (2016:1). Taking its cue from the convergence of these insights, the paper focuses on the multi-layered gatekeeping process of Suman’s Scheherazade and explores the ways in which people and institutions have become integral components of its global dissemination.Works CitedDamrosch, David (2003) What is World Literature?

XVI. Yüzyıl Osmanlı Şehnâmecilerinden Seyyid Lokmân’ın Şehinşâhnâme’si
No full textThe shahname [book of kings] manuscripts, which are considered a kind of palace historiography of the Ottoman Empire, started semi-officially with Mehmed II and became a permanent state duty during the reign of Suleiman the Magnificent with the establishment of the office of the shahname writings. Shahname manuscripts were institutionalized in the Ottoman Empire in the 1550s and ended in 1601, with five shahname writers having officially served in this function. This study examines the Shahinshahname of Sayyid Luqman, one of the 16th-century Ottoman shahname writers. Luqman’s work includes events between 982-989 AH (1574-1581 CE) in the first volume of a shahname devoted to Murad III and deals with the main events that started with Murad III’s accession to the throne until 1581, addressing especially the turbulent relations with the Safavid dynasty. Most of the events took place in Eastern Anatolia, Southern Caucasus, and Northwestern Iran during these conflicts. The work describes the events through their details and qualities and is especially important in terms of shedding a narrative light on the realities of the period in which the author lived. This study first briefly provides information about the birth and development of shahname writing in the Ottoman Empire before going on to examine Sayyid Luqman’s life, literary personality and works. The study will identify the content and orthographic features of the single surviving copy of the manuscript registered in Istanbul University Rare Works Library under FY 1404
