Comparing the Performances of GARCH-type Models in Capturing Cryptocurrencies Volatility

The analysis of cryptocurrencies market behaviour is receiving significant attention from researchers and practitioners in the last decades. This paper aims at contributes to volatility estimations of the cryptocurrencies helping to highlight the main stylized facts and characteristics. The performance of different specifications of volatility modelling, within the GARCH class, have been compared through the Model Confidence Set (MCS) over four of the most capitalised cryptocurrencies, namely Bitcoin, Ethereum, Stellar and Ripple. Our empirical findings give evidence of strong asymmetric effects in cryptocurrencies volatility leading to a better performance of asymmetric GARCH specifications.

This paper describes a formula for ﬁnding the distance matrix of a simple connected undirected graph from the powers of the adjacency matrix using Hadamard product on matrices.
Determinant Factors Of Small And Medium-Sized Enterprises Investments And Its Impact On Economic Growth Of South Sulawesi

This research attempts to show an analysis of contributions from various macroeconomic variables which assumably affect investments of Small and Medium-sized Enterprises (SMEs) and impact the economic growth of South Sulawesi. Data for this research were collected from multiple sources spread in 24 regencies/cities of South Sulawesi during the period 2010-2017. There are two primary aims of this research: 1. To investigate the effects of the Human Capital Index especially the education index as well as labors, interest rate, the Indonesian Rupiah exchange rate and inflation on SMEs investments; 2. To ascertain the effects of SMEs investment, the number of labors, interest rate, the Indonesian Rupiah exchange rate and inflation on the economic growth of South Sulawesi. As for the method used, this research applied a survey method with an explanatory approach. It conducted Path Analysis using AMOS V.22 software through its panel data, which is the merging of time series data and cross sections intended to examine the determinants factors of small and medium-sized enterprises investments and its impact on economic growth of South Sulawesi. Further results show that there is an empirical evidence that the Human Capital Index (education index), labors, interest rate, the Indonesian Rupiah exchange rate and inflation has no significant effect on the SMEs investments in Sulawesi Selatan. Simlarly, except the Indonesian Rupiah exchange rate, several factors such as SMEs investments, the number of labors, interest rate, and the Indonesian Rupiah inflation do not affect significantly on the economic growth of South Sulawesi.
Corporate Social Responsibility and Social License to Operate in the Niger Delta: A Case of the SPDC Global Memorandum of Understanding (GMoU)

There has been a buildup of research on the role of the corporation in fostering more equitable social contracts at regional level, as an aspect of stakeholder relations in developing countries. A body of literature analysed approaches for measuring Social License to Operate (SLO), notable among them is a proposition of elements to be acquired to build SLO. In continuing the dialogue between theory and practice, the paper applied the elements of legitimacy, credibility and trust in assessing the perception of SLO in the Niger Delta of Nigeria. The article is a case analysis of the Shell Petroleum Development Company of Nigeria (SPDC) which aims to give an account of the stakeholder‟s view of the company‟s efforts to obtain SLO. In the case analysis, the paper outlined that the engagement approach of the SPDC‟s in the Global Memorandum of Understanding (GMoU) process has had little impact on the community‟s perceptions of the company‟s credibility and trust. The paper concludes that while SPDC maintained social legitimacy through improved ownership of GMoU projects and programmes, credibility under the current model is at a fragile level. The analysis further argues that corporations‟ risks rejection if trust is not developed through collaboration and shared experience in the implementation of community development. The paper recommends that models for community stakeholder relationships should be made more effective through the guidance of frameworks such as the right to Free, Prior and Informed Consent (FPIC) in their engagement with host communities.
PII: S0161-5890(01)00110-9

The effects of the antioxidant -lipoic acid (LA) on the proliferation of mitogen-stimulated human peripheral blood lymphocytes (HPBL) were investigated in comparison to its effects on the proliferation of two leukaemic T cell lines, Jurkat and CCRF-CEM. At low mM concentrations, LA inhibited in a dose-dependent manner DNA synthesis of HPBL stimulated with either phorbol myristate acetate (PMA) in combination with ionomycin (IoM), or phytohaemagglutinin (PHA). At similar concentrations, LA inhibited the proliferation of Jurkat and CCRF-CEM cells. However, LA was preferentially cytotoxic to the leukaemic cell lines. The selective toxicity of LA to Jurkat cells was shown by electron microscopy (EM) to be due to the induction of apoptosis. Furthermore, LA had different effects on the secretion of interleukin-2 (IL-2) and steady-state levels of IL-2 mRNA in mitogen-stimulated HPBL depending on the mitogens used. LA dramatically increased the induction of IL-2 mRNA and IL-2 protein secretion in PMA/IoM-stimulated HPBL, whereas it inhibited these in HPBL stimulated with PHA. The differential effects of LA on normal and leukaemic T lymphocytes may indicate a new route towards development of therapeutic agents. © 2002 Elsevier Science Ltd. All rights reserved.

ALGEBRAIC EQUATIONS WITH LINEAR SHIFT OPERATORS ON SEQUENCES

In this note we recall (see also [8]) the structure of all recurrent sequences which satisfy a fixed recurrence relation, with entries in a perfect field. As a consequence of these considerations we give a reasonable proof for the known result that the Hadamard product of two recurrent sequences is also a recurrent sequence.

Microsoft Word-3.4 CHF enhancement Mori 20160427.docx

3.4 Critical heat flux enhancement in saturated pool boiling Abstract Pool boiling has been used for cooling in numerous thermal energy dissipation systems, such as high-power electronics, heat exchangers, and nuclear reactors. The advantage of pool boiling is that a high heat flux can be removed passively while maintaining a low superheat, as compared with natural/forced convection without phase change. However, the heat removal capacity is limited by the upper limit of cooling, i.e., the critical heat flux (CHF), where the heat transfer coefficient decreases dramatically because the boiling regime is changed from nucleate boiling to film boiling. Therefore, the CHF enhancement is of great interest to engineers and researchers. Various surface modifications of the heated surface have been proven to effectively enhance the CHF in saturated pool boiling. Especially novel CHF enhancement technique using a honeycomb porous plate will be introduced in this section. Key word: Saturated pool boiling, Critical heat flux, CHF, CHF enhancement, Critical heat flux enhancement, honeycomb porous plate, nanofluid, high heat flux removal 3.4.
PHYTOCHEMICAL ANALYSIS OF Enteromorpha flexuosa AND Ulva lactuca: A COMPARATIVE STUDY

South coastal line of Tamil Nadu consists of a wide variety of seaweeds that are having abundant bioactive compounds which are useful in drug design. In this investigation, various solvent extracts of Enteromorpha flexuosa and Ulva lactuca were analyzed qualitatively of their bioactive compounds. Results revealed that extracts of U.lactuca have more phytochemical constituents than the extracts of E.flexuosa. Phenol, Tannin and cardiac glycosides were present in a higher amount in the extracts of E.flexuosa. Cardiac glycoside and phlobatanin was found to be abundant in the extracts of U.lactuca. Amino acids and carbonyl compound were found to be absent in both algal extracts.
Mapping of the Egusi Seed Trait Locus (eg) and Quantitative Trait Loci Associated with Seed Oil Percentage in Watermelon

The egusi watermelon (Citrullus lanatus) is popular in West Africa for its oil and protein-rich seed, which is consumed in soups and stews. The egusi phenotypic trait is controlled by a single recessive gene (eg) and is characterized by large seed size and fleshy, thick pericarp. An F2 mapping population was derived from Strain II (PI 279461) of the Japanese cultivar Yamato-cream with normal seed type and low seed oil percentage (SOP = 25.2%) and an egusi type from Nigeria (Egusi (PI 560023)) with high SOP (40.6%). Genetic analysis confirmed that the egusi seed trait is controlled by a single recessive gene (eg) and the location of the gene was mapped to 57.8 cM on linkage group (LG) 2, between markers NW0248325 and NW0250248. Four main quantitative trait loci (M-QTL) were identified for SOP in the population with the eg locus contributing 84% of the explained phenotypic variation (R 2 ). A significant epistatic interaction (E-QTL) was identified between, the eglocus and an M-QTL on LG 9B. The present study reports the location of the eg locus responsible for the egusi seed trait in watermelon on LG 2 as well as M-QTL and E-QTL associated with SOP.
TEACHER’S PERSONALITY TRAITS AND THEIR TEACHING EFFECTIVENESS: IMPORTANT FACTORS FOR STUDENT’S SUCCESS

This is a literature-based paper that tries to establish the fact that relationship exist between teacher’s personality and their teaching effectiveness which has impact on student’s success. The paper looked at the definitions of personality traits and its dimensions focusing on The Big Five Model; extroversion, agreeableness, conscientiousness, neuroticism and openness. Teacher effectiveness was explored before exploring the relationship between teachers teaching effectiveness and teacher personality traits. The writer concludes the paper by highlighting how teacher’s personality and their teaching effectiveness influences student’s success. She then recommended that teachers must be consciously aware of the above fact. And also know that personality traits are not inborn and are not permanent as was the belief before because some studies have shown that these traits can be worked on and can be improved on and also be changed. They should therefore be able to have the ability and responsibility to develop and maintain a conducive atmosphere in the classroom that supports the students for effective learning since the climate of the classroom is largely dependent on the teacher’s personality.
Experiencing 'Otherness': Teacher Educators' Journey with First Year Pre-Service Teachers.

Teaching is complicated, and is compounded by changes in the education landscape as far as diversity is concerned. This has forced education planners to reconsider the manner in which initial teacher education programs are structured, to meet the needs of the diverse classroom population. This study reports on the experiences of South African university teacher educators, from diverse backgrounds, who facilitated a first-year education module, “The Individual in Context”, which relates to the way identity is constructed and, as a result, ‘otherness’ is perceived. If pre-service teachers are to adjust to the new, diverse university context, they constantly have to navigate and negotiate the university space, while re-evaluating and reconstructing their own perceptions of ‘otherness’. The article argues that, in order for the teacher educators to effectively facilitate the module, they, too, had to subject themselves to a soul-searching process of reflection, re-evaluation and reconstruction of their own perceptions of ‘otherness’. A narrative methodology was employed to explore how these teacher educators’ own identities were constructed, and how this influenced their perceptions of ‘otherness’. The findings of the narratives reveal that these teacher educators constantly had to unlearn prior understandings of ‘otherness’.
THE EFFECT OF THYROID FEEDING ON THE MOULTING PROCESS AND FEATHER STRUCTURE OF THE DOMESTIC FOWL

In the course of investigations on some of the endocrines and their functional correlations in the domestic fowl, it was observed that the addition of desiccated thyroid to the ration of Brown Leghorn and White Leghorn chicks led to striking modifications in the form of the first set of rectrices, and in the course of the first moult (Horning and Torrey, I923). The form of the rectrices was modified conspicuously by the shortening of the vane and the lengthening of the naked region of the shaft. A characteristically "quilled" feather was the result, though somewhat reduced in total length. The course of the moult was modified by the maintenance of base-to-tip continuity between first and second rectrices, in sharp contrast to the normal independent and discontinuous development of these feathers. The results of this experimentally produced hyperthyroidism, and others to be considered in another place, were then examined for the light they might throw upon the r6le of the thyroid hormone in feather differentiation, possibly in processes of differentiation in general. Feathers afford certain advantages as material, for they give permanent records of the progressive changes that occur in the feather germ during their development. But it is only of such a period that they do give reliable records, obviously enough, for once grown, they are removed from the influence of experimental procedures to which they might earlier have been susceptible. 2.
Integrating management of Pittosporum undulatum with other environmental weeds in Sydney's urban bushland

Natural bushland is a dwindling resource in the Sydney Metropolitan Area, not only because of direct clearing, but also because uncontrolled impacts from surrounding development have caused increasing degradation over time. Community change has been characterized by invasions of environmental weeds, and consequent displacement of many indigenous species. A few locally native species, Pittosporum undulatum in particular, have emerged as environmental weeds. Invasion of new habitats within a species' natural geographic range must be recognized, since their impact on natural communities can be as serious as that of the worst exotic invaders. Factors implicated as the immediate cause of environmental weed invasions include increased human-induced dispersal by birds, anthropogenic disturbance, suppression of fire and increased moisture and nutrients. Management of plant invasions often includes mitigation to reduce impacts of the immediate causes. Strategies to maximize the success of mitigation by identifying and ameliorating the factors which impact bushland from remote sources are discussed. Practical recommendations for restoration of degraded sites are given. Native weeds such as P. undulatum require specialized treatment within an integrated environmental weed management strategy. It is stressed that application of the best management strategies available will be wasted if more fundamental issues related to current planning practices are ignored. Uncoordinated and ad hoc decisions are continuing to reduce urban bushland to mere remnants with high edge-to-interior ratios. Only when these practices are recognized and addressed can long-term success in the treatment of environmental weed invasions be achieved by the many excellent restoration techniques being developed.
Improving Trust in Software through Diverse Double-Compiling and Reproducible Builds

There is implicit trust involved when using computer software. Opensource software attempts to inspire more trust, by giving access to the source code. Nevertheless, malicious compilers or someone with malicious intent can create malicious compiled code, even from non-malicious source code. Further, comparing source code and compiled code for equivalence is an undecidable problem. This thesis explores how software can be manipulated so that source code and compiled code are no longer equivalent and what can be done to increase the trust that they are equivalent. One such way of manipulating the compiled code is through a malicious compiler. I demonstrate this by implementing a self-replicating compiler attack against the Go language compiler, a modern industrial-strength compiler. The attack is similar to the well-known trusting trust attack and can infect a new compiler when it is being compiled, even when the compiler is compiled from non-malicious source code. In the thesis, I also discuss other, real-world, compiler attacks such as XcodeGhost and W32/Induc. The attacks show that compiler attacks are viable and a real threat. I discuss how reproducible builds can be used to increase the trust in compiled code, when the source code is available. Also discussed, is how Diverse Double-Compiling (DDC) can be used to detect self-replicating compiler attacks. I introduce a variant of DDC using more than two compilers for bootstrapping, this variant has not previously been described. This new variant can, by utilising parallel trust combinations, increase the trust in the verified compiler beyond regular DDC and identify which compiler has inserted a self-replicating attack. The new variant is implemented, and used to detect the previously implemented self-replicating attack.
Phloem hydrostatic pressure relates to solute loading rate: a direct test of the Münch hypothesis.

According to the Münch hypothesis, a flow of solution through the sieve tubes is driven by a hydrostatic pressure difference between the source (or collection) phloem and the sink (or release) phloem. A high hydrostatic pressure is maintained in the collection phloem by the active uptake of sugar and other solutes, with a concomitant inflow of water. A lower pressure is maintained in the release phloem through solute unloading. In this work we directly test the role of solute uptake in creating the hydrostatic pressure associated with phloem flow. Solute loading into the phloem of mature leaves of barley and sow thistle was reduced by replacing the air supply with nitrogen gas. Hydrostatic pressure in adjacent sieve elements was measured with a sieve-element pressure probe, a cell pressure probe glued to the exuding stylet of aphids that had been feeding from the phloem. Sieve element sap was sampled by aphid stylectomy; sap osmotic pressure was determined by picolitre osmometry and its sugar concentration by enzyme-linked fluorescence assays. Samples were taken with a time resolution of ~2-3 min. In accordance with Münch's proposal a drop in osmotic and hydrostatic pressure in the source phloem following treatment of the source leaf with N2 was observed. A decrease in sugar concentration was the major contributor to the change in osmotic pressure. By observing these variables at a time resolution of minutes we have direct observation of the predictions of Münch.
Participation of the local community in the tourism development of Imbros (Gokceada)

Planning is essential in order to ensure sustainable development of the regions where tourism starts to develop. Adoption of a participatory planning approach enables the community to benefit from the positive effects of tourism, while alleviating its negative effects. This paper aims to set forth the tourism potential of Gokceada, the largest island of Turkey, to determine the problems in relation with the development of tourism and to provide suggestions on the planning of the Island for the sake of sustainable development. Within this framework, the opinions of the local community on the island's tourism have been called upon by utilizing the Rapid Rural Appraisal (RRA) method. By evaluating the data obtained from RRA, which is considered as a form of the participatory approach, suggestions have been developed. Key words: Rapid rural appraisal, community participation, sustainable tourism, Gokceada, island.
Lightweight Preemptible Functions

Lamenting the lack of a natural userland abstraction for preemptive interruption and asynchronous cancellation, we propose lightweight preemptible functions, a mechanism for synchronously performing a function call with a precise timeout that is lightweight, e cient, and composable, all while being portable between programming languages. We present the design of libinger, a library that provides this abstraction, on top of which we build libturquoise, arguably the rst generalpurpose and backwards-compatible preemptive thread library implemented entirely in userland. Finally, we demonstrate this software stack’s applicability to and performance on the problems of combatting head-ofline blocking and time-based DoS attacks.
Last but not least. Positive scotomata of the blind spots during abrupt changes between darkness and twilight.

twilight Author's profession : ophthalmologist. Conditions of the eyes : clear corneae at lenses, fundi normal. Acuity of both eyes: 1.0. Visual fields : normal. Positive scotomata of the blind spots were observed under the following conditions: (1) for the first time at the age of 72 years, (2) only after long sunny days, (3) only during vacationsöwithout daily stress, and (4) in the evening or in twilight conditions prior to sleeping or waking in the morning, during scotopic vision (black and white) or in the early stages of mesopic vision (with minor colour). Under these conditions, when opening the eyes and looking towards a gray ^white ceiling, a dark spot (positive scotoma) corresponding to the blind spot could be seen laterally and a little downwards from the fixation point (figure 1). On closing the eyes, a white spot (positive scotoma) could then be seen in the dark-gray space, corresponding again to the blind spot (figure 2). After this, as long as the light remained
The response of dairy cows grazing a nitrogen fertilized grass pasture to a supplement of protected casein

Summary Twenty-one Jersey cows in their 6th–8th week of lactation grazed Chloris gayana pastures fertilized with nitrogen and were treated in three ways, no casein (control), casein (1 kg/cow/day) or formal-casein (1 kg/cow/day) in seven 3 x 3 Latin squares to measure the effect of protein protection on milk yield and milk composition. Additional animals fitted with oesophageal and rumen fistulae were used to determine composition of the diet selected and rumen characteristics on three treatments. Cows ingested herbage containing 20% crude protein with a protein solubility of 40%. The untreated casein supplement increased milk yield by 3%, fat 5% and protein 2·4%. Formal-casein produced 20% (3·3 kg/day) more milk than the control, a 13% higher yield of butterfat and 27% more protein. Rumen ammonia concentrations in the afternoon were similar for the control and formal-casein supplemented cows (21 and 23mg/100ml) but significantly higher when casein was fed (74 mg/100 ml) indicating extensive deamination of the untreated protein. Yields of C4–C16 fatty acids in milk fat were 8 and 21% higher for the casein and formal-casein treatments than for the controls, which together with the higher live weight of formal-casein supplemented cows indicated that the milk yield response to the protein supplements was mainly due to a higher daily intake of herbage.
