Essays on testing for stationarity possibly with seasonality and a structural change

The main purpose of this doctoral dissertation is to derive the test statistic for the null hypothesis of stationarity against a unit root and to investigate its asymptotic properties. Since many economic time series are often observed quarterly and then have seasonal patterns, and sometimes a structural change of the series is detected, we should carefully construct the testing procedures taking such properties of the series into account. The construction of the dissertation is as follows:
Serum lipids and lipoproteins in clinically healthy Caspian miniature horses.

Blood samples were collected from the jugular vein of 50 clinically healthy Caspian miniature horses according to their age (1.5-3, 3-5 and >5 years) and sex. Variations in the serum concentrations of cholesterol, triglycerides, total lipid, very low-density lipoprotein, (VLDL-cholesterol), low-density lipoprotein (LDLcholesterol) and high-density lipoprotein (HDL-cholesterol) were investigated. The concentrations of cholesterol, triglycerides, total lipid, HDL-cholesterol, LDL-cholesterol and VLDL-cholesterol in the different age groups were significantly different (P<0.05). With an increase in the age of animals there were significant increases (P<0.05) in cholesterol, triglycerides, total lipid, HDL-cholesterol, LDL-cholesterol and VLDL-cholesterol concentrations. However, sex showed no significant differences on the concentrations of these parameters.
Australian Unity Wellbeing Index survey 28.0 : The wellbeing of Australians - The impact of marriage : Report

The Australian Unity Wellbeing Index monitors the subjective wellbeing of the Australian population. Our first survey was conducted in April 2001 and this report concerns the 28 th survey, undertaken in September 2012. Our previous survey had been conducted six months earlier in April. This intervening period corresponded to the 5 th year of the Labor Government, elected in November 2007. It was also marked by continuing apprehension at the unstable international financial situation, with serious problems in Europe. The Australian economy, however, appeared stable. The share market had been stable for a couple of years, at a level well below its peak before the financial crisis. However, unemployment remained at about 5% and for those people with jobs, many were better-off financially due to cuts in interest rates, and so, in mortgage repayments. Each survey involves a telephone interview with a new sample of 2,000 Australians, selected to represent the geographic distribution of the national population. These surveys comprise the Personal Wellbeing Index, which measures people’s satisfaction with their own lives, and the National Wellbeing Index, which measures how satisfied people are with life in Australia. Other items include a standard set of demographic questions and other survey-specific questions. The specific topic for Survey 28 is the consequence of m on wellbeing.
A New Mouse Gene, SRG3, Related to the SWI3 of Saccharomyces cerevisiae, Is Required for Apoptosis Induced by Glucocorticoids in a Thymoma Cell Line

We isolated a new mouse gene that is highly expressed in thymocytes, testis, and brain. This gene, SRG3, showed a significant sequence homology to SWI3, a yeast transcriptional activator, and its human homolog BAF155. SRG3 encodes 1,100 amino acids and has 33–47% identity with SWI3 protein over three regions. The SRG3 protein contains an acidic NH2 terminus, a myb-like DNA binding domain, a leucine-zipper motif, and a proline- and glutamine-rich region at its COOH terminus. Rabbit antiserum raised against a COOH-terminal polypeptide of the SRG3 recognized a protein with an apparent molecular mass of 155 kD. The serum also detected a 170-kD protein that seems to be a mouse homologue of human BAF170. Immunoprecipitation of cell extract with the antiserum against the mouse SRG3 also brought down a 195-kD protein that could be recognized by an antiserum raised against human SWI2 protein. The results suggest that the SRG3 protein associates with a mouse SWI2. The SRG3 protein is expressed about three times higher in thymocytes than in peripheral lymphocytes. The expression of anti-sense RNA to SRG3 mRNA in a thymoma cell line, S49.1, reduced the expression level of the SRG3 protein, and decreased the apoptotic cell death induced by glucocorticoids. These results suggest that the SRG3 protein is involved in the glucocorticoid-induced apoptosis in the thymoma cell line. This implicates that the SRG3 may play an important regulatory role during T cell development in thymus.
Family Functioning and Disability: A Study on mothers of Mentally Disabled Children

Aim: The present study aims to explore the perception that mothers of mentally disabled children have of their family functioning, measuring: the dynamics of the familiar functioning; the perception that the parental couple has about parenting and family functioning; the similarities between fathers and mothers in the perception of these dimensions. Materials and Methods: The sample included 50 mothers of mentally disabled children. The sample was taken from selected special school. They completed: Family Assessment tool was used to assess specific aspects of family functioning, such as problem solving, communication, roles, affective response and involvement, behavioral control and general functioning; Family Adaptability and Cohesion Evaluation Scales t to measure family adaptability and cohesion. Results: Shows that highest percentage (40%) of the sample was in the age group of 20-25years. shows that maximum percentage (68%) of mothers had average family function 20% had poor family function , and 5% very poor family function. The parents of disabled daughters showed significantly higher on following scales: cohesion, communication and satisfaction. In contrast, the parents who have male sons showed high scores in the scale of flexibility. Parents of children with autism reported higher scores than the parents of children with pervasive developmental disorders in the following scales: cohesion, communication and satisfaction. Conclusions: Children depend on their parents and caregivers for stability, safety, support, and assistance in helping them make sense of adverse events and life challenges. By strengthening community support and attending to parent and caregiver needs and well-being, family-serving professionals will be doing their utmost to ensure that the special children and their families thrive
NUSIS at TREC 2011 Microblog Track: Refining Query Results with Hashtags

In this paper, we describe our submission to the TREC 2011 Microblog track. We first use URLs as a clue to discover and remove the spam tweets. Then we use both Lucene and Indri to generate a ranked list of results for each query, together with their relevance scores. After that, we use the scores to find out useful hashtags relevant to the query, therefore some previously lower-ranked tweets can be discovered and are re-ranked higher. Query reformulation is considered in two of the four runs in our submissions.

Uberization Meets Organizational Theory: Platform Capitalism and the Rebirth of the Putting-out System

During the 20th century, the large managerial corporation became the dominant economic institution of capitalism (Chandler, 1977). However, the current development of peer to peer platforms entails major economic, organizational and social transformations (Evans & Gawer, 2016; Sundararajan, 2016). While these platforms are often depicted as new organizational innovations born of the digital world, we develop an alternative analysis rooted in organizational theory and history. The central argument is that the emergence of platform capitalism should be understood as a digital reincarnation of the putting-out system (Hounsell, 1984), a pre-industrial organizational form that preceded the emergence of manufacturing and the managerial corporation. Implications of this analysis are discussed in terms of management of labor, financialization, and platforms accountability.
Implementation of real-time watermarking scheme for high-quality video

Digital watermarking for video helps protect the copyright of the video content. In most watermark applications, an embedding procedure should be built at low costs and the embedded watermarks should have robustness against various unintentional or malicious attacks. This paper addresses implementation issues for real-time watermark embedding scheme of High Definition(HD) resolution video on a personal computer. This paper provides some performance optimization guidelines and a simplified Human Visual System (HVS) method for fast and robust watermark embedding. Demonstration shows a real-time watermark embedding process including HD MPEG-2 video decoding, watermark embedding and displaying on an Intel architecture personal computer. Experimental results show optimized embedding performances and robustness against several malicious attacks commonly happened to videos. From the results, our implementation solution improved the embedding performance suitable for real-time watermark embedding for HD video.
An Evaluation of Feature Selection Methods for Positive-Unlabeled Learning in Text Classification

Feature Selection is important in the processing of data in domains such as text because such data can be of very high dimension. Because in positive-unlabeled (PU) learning problems, there are no labeled negative data for training, we need unsupervised feature selection methods that do not use the class information in the training documents when selecting features for the classifier. There are few feature selection methods that are available for use in document classification with PU learning. In this paper we evaluate four unsupervised methods including, collection frequency (CF), document frequency (DF), collection frequency-inverse document frequency (CF-IDF) and term frequency-document frequency (TF-DF). We found DF most effective in our experiments.
Cost and Accuracy Aware Scientific Workflow Composition for Service-Oriented Environments

Large-scale scientific data analysis projects have catalyzed service-based workflow management systems. We present an approach for integrating user preferences on completion time and workflow accuracy in a workflow composition system. The relationship between workflow execution time and the accuracy of results is exploited by our workflow system. Specifically, our system is equipped with a way for users to define cost models on service completion time and error propagation (prevalent in many scientific and data analysis applications). Together with these models and an ontology for describing web service and data dependences, our system plans service-based workflows to answer high-level queries. Our system was evaluated under a real service-based environment against user constraints on time, accuracy, and network bandwidth variations. In the worst case in our experiments, we observed an average deviation of 14.3 percent below the desired time constraints, which suggests that our system is time-conservative. Within varying network bandwidth environments, we can also meet time constraints through sampling, and only a 12.4 percent deviation below time expectations are observed on average. We further show that, though negotiating with services' error models, our system is capable of planning data reduction measures (e.g., sampling) directly within workflow plans to achieve the desired accuracy.
Cortical microtubule nucleation can organise the cytoskeleton of Drosophila oocytes to define the anteroposterior axis

Many cells contain non-centrosomal arrays of microtubules (MTs), but the assembly, organisation and function of these arrays are poorly understood. We present the first theoretical model for the non-centrosomal MT cytoskeleton in Drosophila oocytes, in which bicoid and oskar mRNAs become localised to establish the anterior-posterior body axis. Constrained by experimental measurements, the model shows that a simple gradient of cortical MT nucleation is sufficient to reproduce the observed MT distribution, cytoplasmic flow patterns and localisation of oskar and naive bicoid mRNAs. Our simulations exclude a major role for cytoplasmic flows in localisation and reveal an organisation of the MT cytoskeleton that is more ordered than previously thought. Furthermore, modulating cortical MT nucleation induces a bifurcation in cytoskeletal organisation that accounts for the phenotypes of polarity mutants. Thus, our three-dimensional model explains many features of the MT network and highlights the importance of differential cortical MT nucleation for axis formation.

Adaptive consensus tracking control of uncertain nonlinear systems: A first-order example

In this paper, we consider the problem of designing distributed adaptive consensus tracking controllers for multiple nonlinear systems with unknown parameters and external disturbances. The desired trajectory is time varying given by the state of a reference system, which is only available to a portion of the group of the systems. Besides, the dynamics of the reference state is bounded but unknown to all of the systems. The communication graph characterizing the interactions among the systems is assumed to have undirected, fixed and connected topology. By introducing distributed estimators for the bound of the reference dynamics, two control schemes are proposed to address the problem. In the first scheme, a sign function is employed and perfect consensus tracking can be achieved. In the second scheme, an alternative control law is developed and the chattering phenomenon caused by the sign function can be reduced. However, new challenge will be triggered which is to compensate for possible destabilizing effects of the coupling elements relating to local parameter estimation errors and the synchronization errors of the neighbors. The overall communication graph is firstly reduced to an undirected spanning tree with single system notified of the reference state. Based on this, new synchronization error for each subsystem is then defined as the weighted distance relative to only one of its neighbors. It is shown that all the synchronization errors will converge to a prescribed bound which can be made as small as desired in this case.
Correlation of Nitrogen Sorption and Confocal Laser Scanning Microscopy for the Analysis of Amino Group Distributions on Mesoporous Silica

Aminopropylalkoxysilanes are frequently used for the functionalization of mesoporous silica. The analysis of amino group distributions on arrays of silica nanochannels by a combination of nitrogen sorption and confocal laser scanning microscopy provides valuable insight into the mechanisms underlying the interaction of these silanes with mesoporous silica surfaces. Tendencies towards external surface functionalization, non-uniform distribution in the pores, and hydrolysis of the silica framework are shown to depend to a large extent on the mobility of the aminopropylalkoxysilane molecules, which can be adjusted by the number and type of alkoxy groups.
Interpreting document collections with topic models

This thesis concerns topic models, a set of statistical methods for interpreting the contents of document collections. These models automatically learn sets of topics from words frequently co-occurring in documents. Topics learned often represent abstract thematic subjects, i.e Sports or Politics. Topics are also associated with relevant documents. These characteristics make topic models a useful tool for organising large digital libraries. Hence, these methods have been used to develop browsing systems allowing users to navigate through and identify relevant information in document collections by providing users with sets of topics that contain relevant documents. First, we look at the problem of identifying incoherent topics. We show that our methods work better than previously proposed approaches. Next, we propose novel methods for efficiently identifying semantically related topics which can be used for topic recommendation. Finally, we look at the problem of alternative topic representations to topic keywords. We propose approaches that provide textual or image labels which assist in topic interpretability. We also compare different topic representations within a document browsing system.
The Power of Implicit Social Relation in Rating Prediction of Social Recommender Systems

The explosive growth of social networks in recent times has presented a powerful source of information to be utilized as an extra source for assisting in the social recommendation problems. The social recommendation methods that are based on probabilistic matrix factorization improved the recommendation accuracy and partly solved the cold-start and data sparsity problems. However, these methods only exploited the explicit social relations and almost completely ignored the implicit social relations. In this article, we firstly propose an algorithm to extract the implicit relation in the undirected graphs of social networks by exploiting the link prediction techniques. Furthermore, we propose a new probabilistic matrix factorization method to alleviate the data sparsity problem through incorporating explicit friendship and implicit friendship. We evaluate our proposed approach on two real datasets, Last.Fm and Douban. The experimental results show that our method performs much better than the state-of-the-art approaches, which indicates the importance of incorporating implicit social relations in the recommendation process to address the poor prediction accuracy.
Parametrization of joint OFDM-based radar and communication systems for vehicular applications

The design process of a joint radar and communication system employing OFDM is analyzed. In particular, the question on how to choose OFDM modulation parameters such as carrier distance, guard interval length, frame length or pilot design is studied. Such systems use the same OFDM frames to transmit data and image the surroundings, so both radar and communication are affected by the choice of these parameters. The main design criteria for the radar component are accuracy of distance and speed measurements, whereas the communication subsystem needs to be designed such that it transmits robustly through a mobile communication channel. As these design criteria often are antipodal, arguments for choosing a particular set of modulation parameters are discussed. The presented design process is applied to the case of a vehicular (car-to-car) communication, in which moving participants communicate in the 24 GHz range.
A New Effective Collaborative Filtering Algorithm Based on User's Interest Partition

Traditional collaborative filtering algorithms all suffer from inaccurate recommendation and bad scalability. In this paper, we propose a new collaborative filtering algorithm based on user¿s interest partition. We divides user¿s whole interest into pieces. Each piece of interest is called interest unit. And the similarity between users on interest unit is named local similarity. The similarity between users on whole interest is named holistic similarity which is similar with the traditional similarity. Our approach searches the nearest neighbors of active user according to the linear combination of local similarity and holistic similarity. Through experiments, the algorithm can solve the problem of high sparsity on user-item matrix. Our algorithm also has a better quality on recommendation according to experiments.
The impact of providing rapid diagnostic malaria tests on fever management in the private retail sector in Ghana: a cluster randomized trial

Objective To examine the impact of providing rapid diagnostic tests for malaria on fever management in private drug retail shops where most poor rural people with fever present, with the aim of reducing current massive overdiagnosis and overtreatment of malaria. Design Cluster randomized trial of 24 clusters of shops. Setting Dangme West, a poor rural district of Ghana. Participants Shops and their clients, both adults and children. Interventions Providing rapid diagnostic tests with realistic training. Main outcome measures The primary outcome was the proportion of clients testing negative for malaria by a double-read research blood slide who received an artemisinin combination therapy or other antimalarial. Secondary outcomes were use of antibiotics and antipyretics, and safety. Results Of 4603 clients, 3424 (74.4%) tested negative by double-read research slides. The proportion of slide-negative clients who received any antimalarial was 590/1854 (32%) in the intervention arm and 1378/1570 (88%) in the control arm (adjusted risk ratio 0.41 (95% CI 0.29 to 0.58), P<0.0001). Treatment was in high agreement with rapid diagnostic test result. Of those who were slide-positive, 690/787 (87.8%) in the intervention arm and 347/392 (88.5%) in the control arm received an artemisinin combination therapy (adjusted risk ratio 0.96 (0.84 to 1.09)). There was no evidence of antibiotics being substituted for antimalarials. Overall, 1954/2641 (74%) clients in the intervention arm and 539/1962 (27%) in the control arm received appropriate treatment (adjusted risk ratio 2.39 (1.69 to 3.39), P<0.0001). No safety concerns were identified. Conclusions Most patients with fever in Africa present to the private sector. In this trial, providing rapid diagnostic tests for malaria in the private drug retail sector significantly reduced dispensing of antimalarials to patients without malaria, did not reduce prescribing of antimalarials to true malaria cases, and appeared safe. Rapid diagnostic tests should be considered for the informal private drug retail sector. Registration Clinicaltrials.gov NCT01907672
OBSERVATION OF FILAMENTS IN THE ADRENAL OF ANDROGEN-TREATED RATS

Filaments have been reported in the cytoplasm of cells as diverse as columnar epithelial cells (1), epidermal cells (2), neuroglia (3), and neurons (4) . In endocrine tissue, concentrations of filaments have been observed in the androgen-producing interstitial cells of the testis (5, 6), whereas the number of these filaments in the cytoplasm of other endocrine tissues is so small that they are only occasionally seen . Increased numbers of filaments have been produced experimentally in neurons (7, 8) and in cultured fibroblasts (9) by treatment with vinblastine or vincristine, inhibitors of mitosis . In the present study, we report the occurrence of similar, conspicuous arrays of filaments in the adrenal gland of androgen-treated rats .
