Learning temporal sentiment from business news : a computational approach

This thesis concerns is about the analysis of textual sentiment using computational approaches. Textual sentiment reflects the opinions and attitudes expressed through textual communications. With the advent of the Internet and World Wide Web, individuals are being exposed to an ever-growing amount of sentiment through various channels; such information can have powerful effect on how people make decisions. Because of this, computational approaches to sentiment analysis has attracted increasing interest from researchers in the past two decades. The goal of sentiment analysis is to determine whether a piece of text conveys a positive or negative evaluation on a certain topic. Being able to identify and comprehend sentiment expressed by the public at a large scale can be very useful to many applications. One such application is to use sentiment conveyed in business news to explain the behaviours of financial markets. In this thesis, I have proposed an extended model for describing the interactions between news sentiment and financial markets. This extended model recognises two different types of news sentiment: (i) the retrospective news sentiment, which refers to the sentiment that is associated with news stories that recount past events in the market; and (ii) the prospective news sentiment, which refers to the textual sentiment in business and financial news that is associated with speculations and projections about the future developments of the market. A method that can automatically extract sentiment-laden language patterns for the temporal sentiment classes was developed. The method models the texts in news articles as a mixture of lexical items distributions, where each distribution characterises one of the temporal sentiment classes. A supervised maximisation expectation algorithm was derived to infer these distributions given a corpus and a market performance measure as the target. The supervision was enforced by implementing different conditional probability distributions for returns given the underlying temporal sentiment class of the news article. The method was implemented by a system comprising two components, CiCui and TSMiner, which was used to conduct a case study on firm-level data. The results of the study suggested it is mainly changes in the market that leads to changes in the news sentiment, and retrospective news sentiment is in general more prevalent in business news. Also noted was that word dependencies seem to be able to capture prospective sentiment than unigrams. It has been shown that the method proposed in this thesis slightly outperforms content analysis methods used with either the GI or Loughran and McDonald’s sentiment dictionary.
Dynamic task distribution in a heterogeneous loosely-coupled distributed computer system

This thesis studies the problem of dynamic distribution of tasks between hosts in a heterogeneous, loosely-coupled, distributed computing system. The goals of the study are to (a) demonstrate reduced execution time in a computer program making subroutine calls to be executed on a computer (or computers) which will yield better performance than the one on which the program was initiated, (b) demonstrate the feasibility of dynamic task-to-host binding, (c) demonstrate the feasibility of a programmertransparent methodology of distributed computing using a library approach. These goals are partially realized using the Remote Procedure Call protocol in a programmertransparent framework of library calls. Examples of a distributed library, libHCS, and an associated daemon, HCSdaemon, implemented in support of these goals, are analyzed for their feasibility and effectiveness in solving this problem. Although results of the study fail to demonstrate reduced execution time, dynamic task-to-host binding and programmer transparency were achieved. Further study is indicated.
Identifikacija govornika u forenzičkoj akustici i fonetici

Forensic acoustics and phonetics is a relatively new interdisciplinary area that determines relevant facts in court proceedings by encompassing technical, biomedical, humanities and social sciences. This review paper shows one of the areas that forensic acoustics and phonetics covers, and that is speaker identification. Invention of sound recording and reproduction equipment, various tools for acoustic voice manipulation and the spectrogram are key events that made the speaker identification what it is today. Experts in the areas of phonetics, linguistics, voice and speech pathology or (electro)acoustics can perform voice comparisons with the goal of speaker identification but everything under the set of rules that the International Association for Forensic Phonetics and Acoustics (IAFPA) dictates. Two methods of voice and speech assessment intertwine and complement each other, subjective/auditive and objective/acoustic. In recent years great attention in this area is given to the question: Is our voice truly unique like our fingerprint. The question of voice uniqueness ties to itself the descriptions of acoustic voice characteristics (F0, jitter, shimmer, formants) and speech characteristics (articulation, resonance, prosody, language characteristics) that make our voice and speech recognizable, and on the other hand all other characteristics that can influence its variability (stress, emotions, demographics, medical condition) also including speech pathology disorders. In Croatia there are no permanent court experts in this area, nor is there a specialized establishment, thus there are no set norms or procedures. Even though the number of felonies that could be solved by using expert testimony in this area is increasing, there are only a handful of individuals who perform these services in Croatia. Therefore the goal of this paper is to show the today’s status of forensic acoustics and phonetics in the area of voice and speech expertise through an overview of current scientific papers, together with the possibilities, limitations and novelties in this area.
Cesarean section - short term maternal complications related to the mode of delivery

Nanneli Pallasmaa Cesarean section. – short term maternal complications related to the mode of delivery Department of Obstetrics and Gynecology. University of Turku, Turku, Finland. Annales Universitatis Turkuensis 2014 Cesarean section (CS) is the most common major surgery performed on women worldwide. CS can save the life of the mother or the fetus, but is associated with the typical complications of any major surgery: hemorrhage, infection, venous thromboembolism and complications of anesthesia, sometimes leading to maternal death. Recently there have been several reports from well resourced countries on increased severe maternal morbidity and even mortality. Increased rates of CS, obesity and older mothers may explain this rise. The aim of this thesis is to study the rates and risk factors of short term maternal complications associated with CS. Also, we compared maternal morbidity by mode of delivery and over time. The complication rates were assessed in a prospective study involving 2496 CS performed in the 12 largest delivery units in Finland in 2005. The rates of severe complications were studied by mode of delivery in a register-based study comparing national cohorts in 1997 and 2002. The impact of several risk factors on severe maternal morbidity by mode of delivery was studied in a register-based study of all singleton deliveries in 2007-2011. In the prospective study, 27% of the women who underwent CS had one or more intraoperative or postoperative complications during their hospital stay, and 10% had a severe complication. In the register-based study the incidence of life-threatening maternal complications was 7.6 in 1000 deliveries. The incidence was lowest for vaginal delivery (VD), followed by instrumental VD and elective CS, and highest in emergency CS. An attempt of VD, including the risks associated with emergency CS, seems to be the safest mode of delivery, even for most high-risk women.
HISTORICAL DEVELOPMENT OF HEALTH MANAGEMENT TRAINING IN TURKEY

Today, health management training, with its increasing interest and importance, has had an important part in training programs in developed countries. Global competition, the purpose of profit and management challenges arising from the structure of health institutions entailed delivery of health institutions to professional health administrators. The aim of this study is to study the historical process of health management training in Turkey. In view of the literature, it is seen that the first health management began in the area of hospital administration. During the Ottoman era, hospital managers were selected from non-physician people. During that period, all the administrative and financial affairs of a hospital were conducted by “Mudir-i hastane” i.e. a hospital manager. The chief physician of a hospital had a position dealing with patient care and coordination of subordinate physicians. After the proclamation of the Republic, the first school established to train students in the field of management of health institutions was Health Administration High School, which was established within the Ministry of Health, General Directorate of Vocational Education on December 19, 1963. Then, this school was assigned to Hacettepe University in 1982, and it has graduated students under the Faculty of Economics and Administrative Sciences ever since. Now, there are a total of 55 universities providing education at undergraduate level in the field of health management in Turkey. Because of the great importance of health management training for the sector, this study is expected to make a significant contribution to the literature.
Non-holding-back Dynamic Traffic Assignment with signal control: Models and applications

In this thesis, we develop a linear Non-Holding-Back System Optimal Dynamic Traffic Assignment with Signal Control (NHB DTA-SC) formulation underpinned by the Cell Transmission Model (CTM). The formulation not only attains System Optimal (SO) solution but also eliminates the unrealistic vehicle Holding-Back (HB) problem. The embedded signal control model in the formulation namely Signal Control with Realistic Cycle (SCRC) overcomes the trade-off between signal control cycle-length and cell-length and enables us to strike the right balance between computational complexity and solution accuracy. Note that the cell-length of any CTM based DTA model is directly related to the duration of the discrete time-slot. This discretization time interval has a significant impact on DTA solution accuracy as well as attained vehicle density. As the density contributes to vehicle discharged emission, the above fact motivates us to investigate the effect of time-slot duration on emission. To this end, we propose a linear Emission-Based Dynamic Traffic Assignment with Signal Control (EB DTA-SC) formulation. This formulation is free of the HB problem and jointly minimizes emission and travel-time. Our results show that there is a 32% difference between NOX emission estimated by 60-second and 5-second time-scales. In addition to combining emission perspective in an NHB DTA-SC framework, we also analyze structures of the optimal solution of such formulation. As the NHB DTA-SC formulation captures real-life trafi
Psychotherapy Through Video Game to Target Illness Related Problematic Behaviors of Children with Brain Tumor

With the rapid development in serious games, health games have been demonstrated as a useful tool to enhance treatment effects with respect to some problematic behaviors. Every health game has its own game design which can affect the health in a positive manner. In this paper we fixed Imagery Psychotherapy into game design and then developed the 3D Graphical Imagery Psychotherapy video game with cognitive behavioral effects on the children suffering from brain tumor. This therapeutic game attempts to provide a new way to target the psychological illness related to this disease. Experimental user tests were conducted in three hospitals of Pakistan analyzing the different problematic behaviors of a cancer patient before and after the therapy application. The outcome of the study proved that 3D Graphical Imagery Therapy game has been effective in recovering from psychological illness related to brain tumor. The results showed a significant improvement regarding the behaviors, hence this game design found to be effective.

Enhanced Phenylephrine Contractions in Rabbit Carotid Arteries Following Exposure to Haemoglobin from Subjects with Sickle Cell Trait.

We have previously reported raised resting diastolic blood pressure (BP) in subjects with single S-gene inheritance – although the mechanism was unclear. The goal of this study was to characterize, in vitro, the modulatory role of erythrocyte components from subjects with different Hemoglobin (Hb) genotypes on contractile responses induced by phenylephrine (PE) in isolated rabbit carotid arterial smooth muscle. Carotid arteries were isolated from rabbits and cut into 2mm rings, suspended in 20ml organ baths and bubbled with 95% O 2 , 5% CO 2 and isometric contractions examined under an initial load of 1g, at 37 o C and pH 7.4. Contractile responses to EC 70 (M) PE in arterial rings exposed to various erythrocyte components obtained from subjects of different Hb genotypes (AA, AS and SS) were examined in control rings as well as in rings exposed for 30 minutes to (a) intact washed erythrocytes (b) erythrocyte ghosts and (c) haemoglobin solution. Arterial rings were exposed to 50μl of each of the erythrocyte constituents at an adjusted haematocrit of 0.6. The magnitudes of the PE-induced contractions with intact erythrocytes were: 1180±202, 1700±260 and 900±302 for Hb AA, Hb AS and Hb SS respectively (n=13); these values were significantly increased following exposure to various erythrocyte components in the order: RBC> HB > Ghost (P<0.05, respectively). There were no significant differences in PE contractions following exposure to intact erythrocytes and ghosts from subjects with different Hb genotypes; however, exposure to haemoglobin solution significantly enhanced PE contractions in Hb AS subjects than in Hb AA and Hb SS (P<0.05 respectively). In conclusion, we reason that the haemoglobin content of Hb AS erythrocytes may be responsible for the enhanced contractile responses to PE and may explain in part, why diastolic BP values remain high in Hb AS subjects.

Human motion reconstruction based on body-worn sensors

Optical tracking systems are still frequently used in several areas of motion reconstruction, such as military, cinema, virtual reality and medical applications. They recreate the movement of the real character in an avatar easing their study and/or projection onto virtual screens. However, these methods often require an extensive external system composed of infrared cameras, specific software and markers at relevant points of the object/body. Although the accuracy of these systems is extreme, the lack of portability and the associated high cost has led to the investigation of small and mobile alternatives, equally effective but simpler to handle. In this way, the use of inertial systems (IMUs) has recently gained great relevance in several areas of science, allowing to evaluate the changes in the inertial properties of a body. They result from the combination of accelerometer and gyroscopic inertial units that respectively measure linear acceleration and angular velocity. They come in small sizes and without the need for visibility, which expands their possibilities of use. Although orientation measurements obtained with IMUs are reliable in the short term, they tend to deviate from the real value when used for long periods of time. To address these shortcomings, solutions have emerged based on algorithms and the use of additional sensors, such as the magnetometer, sometimes incorporated in the IMU. This project investigates the accuracy of reconstruct human gait with IMUs placed on the lower limbs and pelvis, against commonly used optical systems. The inertial systems used are an Xsens wireless line, the MTw Awinda, consisting of micro-electromechanical systems based IMUs and include 3-axis accelerometer, 3-axis gyroscope and 3-axis magnetometer. The optical system is a Qualysis equipment, available at the Biomechanics Laboratory of the University of Porto. Gait studies were performed here on seven healthy volunteers with both systems operating at 100 Hz. The data (optical and inertial) were converted and treated using a proprietary software, owned by Kinetikos. This document also contains a small preliminary study that intends to evaluate how promising an innovative inertial system is with dimensions 26.7 x 15 x 4 mm and 2g of mass. Mentioned here as Wear, it is also a micro-electromechanical based IMU including 3-axis accelerometer, 3-axis gyroscope and 3-axis magnetometer. A low-tech methodology was used in which the two inertial systems and the optical system were recorded simultaneously at 100 Hz. The set of systems slid repeatedly along a gutter and it was compared the accelerations of the three axes. The results of the tests with volunteers are comparable with the literature with an absolute mean error about 2-3◦and the Pearson correlation coefficient of 0.90 (r). Regarding the sliding test, the absolute mean errors were less than 1 m/s2 with r between 0.91-0.96.
DNA Pool Analysis-based Forgery-Detection of Dairy Products

Food integrity and food safety have received much attention in recent years due to the dramatic increasing number of food frauds. In this article we focus on the problem of dairy products traceability. In particular, we propose an automatic forgery detection system able to detect frauds in milk and cheese. We investigate the use of Short Tandem Repeats analysis data, processed by a Covariance Matrix Adaptation Evolution Strategy algorithm in order to evaluate a traceability score between the products and their producer, and to highlight possible adulterations and inconsistencies. To demonstrate the usability of the proposed heuristic algorithm in a real setup, we also present the results collected from two real Italian farms.
Cervical Lymph Nodal and Esophageal Metastasis In a Patient with Primary Ovarian Carcinoma: A Case Report

Secondary carcinoma of the esophagus occur as a result of direct invasion from a primary tumor of an adjacent structure, invasion from metastatic foci in mediastinal lymph nodes or metastatic hematogenous spread. We report a 40 year old female operated because of the primary ovarian carcinoma and who was admitted with swelling on the neck after five years and with disphagia after eight years since onset of the ovarian resection during the follow-up. She was considered inoperable and only chemotherapy is being administered.
What is known about diabetogenic effects of statins

Od pewnego czasu pojawiają sie dowody na diabetogenne dzialanie statyn. Te informacje pochodzą z badan klinicznych oraz obserwacyjnych i rozchodzą sie wśrod lekarzy i pacjentow, z ktorych cześc moze sie obawiac przepisywania i przyjmowania tych lekow. W tej sytuacji Autorki niniejszej pracy uznaly, ze wazna jest rzetelna wiedza na temat tego ubocznego efektu statyn, zwlaszcza ze są one powszechnie stosowane ze wzgledu na dobrze udokumentowaną korzyśc kliniczną w prewencji chorob sercowo-naczyniowych (ChSN). W artykule przedstawiono wyniki badan klinicznych i metaanaliz oraz opisano przypuszczalne mechanizmy, poprzez ktore statyny mogą powodowac cukrzyce (upośledzenie sekrecji insuliny z komorek β trzustki i zwiekszenie oporności na insuline). Wnioskując, nalezy z naciskiem podkreślic, ze jakkolwiek statyny mogą pogarszac metabolizm glukozy, szczegolnie w podatnych populacjach (kobiety, osoby starsze oraz z elementami zespolu metabolicznego), to korzyści przewazają nad ryzykiem rozwoju cukrzycy. Tak wiec statyny są nadal zalecane jako leki z wyboru w prewencji epizodow sercowo-naczyniowych. Jednakze u pacjentow zagrozonych cukrzycą nalezaloby rozwazyc monitorowanie stezenia glukozy na czczo.
Sudden cardiac death in athletes

Sudden Cardiac Death in Athletes Cardiovascular-related sudden death is the leading cause of mortality in athletes during sport. The incidence of sports-related sudden death of any cause in the general population is 0.5–1.7 per 100,000 persons per year. This is higher in professional athletes, with a reported incidence of sudden cardiac death (SCD) as 1/43,770 participants per year in the National Collegiate Athletic Association (NCAA), and 1/3,100 per year among NCAA Division I male basketball players. In other studies, the reported incidence of SCD ranges from 0.26 to 3.60/100,000 per year with the higher rates seen in African/Afro-Caribbean (black) athletes. For comparison, the incidence of SCD in the general population, not necessarily related to sport, is estimated at 100–200/100,000 annually and increases as a function of advancing age, being 100-fold less in adolescents and adults younger than 30 years (1/100,000) than it is in adults older than 35 years.
Delay Strategies for Anonymizing Mix-Networks' Nodes

Various anonymizing services and networks rapidly grow both in numbers and variance. This thesis is concerned with evaluation of delay strategies in anonymizing mix-networks nodes. The evaluation process includes generation of traffic data, applying different delay strategies such as uniform, exponential, batch delays, and comparison of anonymity and quality of service metrics for these strategies. Metrics of anonymity were obtained from packet delay entropies and validated with simulations. Additional simulations established clear dependency between these metrics and ability of packet mixing to mitigate attacks based on pattern recognition of packet
Barriers for Integration Between Hospitals and the Ministry Of Health in Indonesia

Integration between healthcare providers and the Ministry of Healthis ultimately crucial in order to provide effective and efficient referral and reporting processes. Nevertheless, integration is not an easy task, thus it is deemed necessary to identify the barriers to provide guidance towards an integrated Indonesia Health System. Hence, this research is aimed to analyze the barriers of process integration among hospitals and between hospitals and the Ministry of Health. First, a literature review was performed to identify a set of barriers in healthcare context. Second, interview with experts was conducted to validate the barriers and third, experts filled the questionnaires in order to produce the barriers rank. The top five barriers resulted from this research are as follows: (1) Lack of skilled human resources, (2) Resistance to change, (3) Business process complexity, (4) Lack of integration knowledge, (5) Weak data security technology.
