Service and the principalship

This project is a journey of self-discovery to uncover the connection between my own espoused theory and theory-in-action. My theory is based on the belief that a principal is someone who serves students, staff, parents and community and acts in the best interest of an students. This study is an opportunity for me to reflect upon my practice and look for evidence of my beliefs in my actions. The ways in which a principal pays attention to particular components of the school environment will affect the effectiveness of the school. In this project, I examine the events that as school principal capture and hold my attention. Quite often, people in leadership positions can discuss their philosophical beliefs about education but have difficulty engaging in reflection to determine the alignment among the spoken word, the written word and actions. This project will attempt to test this alignment, to measure the fit between my beliefs and daily practice. Table of
Analyzing the Impact of XML Storage Models on the Performance of Native XML Database Systems – A Case Study

Since XML [1] technology was launched on the world in 1998, there has been an increase in the number of XML documents generated from business transactions. Consequently, both industry and academia have proposed several new kinds of database technologies (i.e. Native XML database (NXD) systems) as an efficient approach for storing, and processing XML documents. This paper presents a comparative analysis of the two storage models namely text-based and model-based used by Open Source Native XML databases to manage their internal storage mechanisms. Additionally, it specifically examines performance evaluation of Berkeley DB XML, Xindice, eXist, and dbXML from the point of view of handling database query operations. Each product is deployed and evaluated using some benchmark techniques. A number of interesting insights are gained from these experiments and a summary of the strengths and weaknesses of each of these products is presented.
Conceptualizing User Satisfaction in the Ubiquitous Computing Era

In this research-in-progress paper we argue that technology in the ubiquitous computing era offers experiences to users that extend well beyond the functional, practical applications offered in the world of work. In this era a realm of engagement is opening up to the individual that transcends the utilitarian, to encompass hedonic and social existence. Our central argument, therefore, is that user satisfaction is a notion which must extend to encompass rich, holistic human experience involving complex and fleeting interactions, driven by highly personal circumstances. We argue that the expectations, requirements and value perceptions of individuals in this dynamic context may only be anticipated and understood if situational factors (such as location, time, context, history-of-use) and quality of life factors (such as life stage, mobility, health, income, background, education) are taken into account. We identify the fundamental differences in key characteristics of user satisfaction between the traditional and ubiquitous computing environments and provide details about our own research approach, in which we are exploring ubiquitous content provision from the perspective of content providers.
Regional Labor Market Disparities in Belgium

Regional labor market discrepancies have been widening in Belgium in the last two decades and are more evident within particular demographic groups. These developments can largely be accounted for by worse matching of people to jobs in the high-unemployment provinces. Using a structural VAR, it is also shown that labor market dynamics in Belgium produce a strong attenuating effect on employment growth, in contrast to the United States where initial labor demand shocks are expanded in the long run. After the short-run adjustment is over, there is less labor migration in Belgium than in the United States or Europe, corroborating the perception that Belgians move "too little. "
Farm Animal Serum Proteomics and Impact on Human Health

Due to the incompleteness of animal genome sequencing, the analysis and characterization of serum proteomes of most farm animals are still in their infancy, compared to the already well-documented human serum proteome. This review focuses on the implications of the farm animal serum proteomics in order to identify novel biomarkers for animal welfare, early diagnosis, prognosis and monitoring of infectious disease treatment, and develop new vaccines, aiming at determining the reciprocal benefits for humans and animals.
Social Preferences Under Risk - An Experimental Analysis

The literature on social preferences provides overwhelming evidence of departures from pure self-interest of individuals. Experiments show that people care about others' well-being and their relative standing. This paper investigates whether this type of behavior persists when risk comes into play. I devise an experiment which sheds light on the interrelation of risk and social preferences by measuring (1) individual risk preferences, (2) interpersonal risk preferences, and (3) social preferences under certainty. The results reveal that a large share of subjects choose to accept more risk or less potential gain than individually preferred in order to increase another subjectâ€™s payoff. Further, the willingness to do so appears to be influenced by the "need" of the other person and her potential relative standing. Surprisingly, the results do not suggest that a subjectâ€™s social behavior under risk is related to his exhibited social concerns exhibited under certainty.
Showing Relevant Ads via Context Multi-Armed Bandits

We study context multi-armed bandit problems where the context comes from a metric space and the payoff satisfies a Lipschitz condition with respect to the metric. Abstractly, a context multi-armed bandit problem models a situation where, in a sequence of independent trials, an online algorithm chooses an action based on a given context (side information) from a set of possible actions so as to maximize the total payoff of the chosen actions. The payoff depends on both the action chosen and the context. In contrast, context-free multi-armed bandit problems, a focus of much previous research, model situations where no side information is available and the payoff depends only on the action chosen. Our problem is motivated by sponsored web search, where the task is to display ads to a user of an Internet search engine based on her search query (context) so as to maximize the click-through rate of the ads displayed. We cast this problem as a context multi-armed bandit problem where queries and ads form metric spaces and the payoff function is Lipschitz with respect to both the metrics. For any > 0 we present an algorithm with regret O(T a+b+1 a+b+2+ ) where a, b are the covering dimensions of the query space and the ad space respectively. We prove a lower bound Ω(T ã+b̃+1 ã+b̃+2 − ) for the regret of any algorithm where ã, b̃ are packing dimensions of the query spaces and the ad space respectively. For finite spaces or bounded subsets of Euclidean spaces, this gives an (almost) matching upper and lower bound.
Reconfigurable control of PWA systems with actuator and sensor faults: Stability

A new approach to the reconfigurable control of piecewise affine (PWA) systems after actuator and sensor faults is presented. The approach extends the concept of virtual actuators and virtual sensors from linear to PWA systems on the basis of the fault-hiding principle. The weak fault-hiding goal is introduced as a relaxation of the asymptotic fault-hiding goal. Sufficient linear matrix inequality conditions for the existence of input-to-state stabilizing virtual actuators and sensors are given that lead to a tractable computational algorithm. The stability of the reconfigured closed-loop system is verified. The approach is evaluated using a system of interconnected tanks.
VEGF-D-enhanced lymph node metastasis of ovarian cancer is reversed by vesicular stomatitis virus matrix protein

Lymphatic metastasis is a poor prognostic factor in ovarian cancer, which correlates to the majority of cancer deaths. Matrix protein (MP) of vesicular stomatitis virus (VSV) exhibits potent antitumor and antiangiogenic activities through inducing apoptosis and inhibiting angiogenesis. In this study, the antitumor and antimetastatic effects of MP were further investigated. Wild-type SKOV3 (WT-SK) cells were successfully transfected with empty vector pcDNA3.1 plasmid, or pcDNA3.1-VEGF-D recombinant plasmid to construct cell lines named EV-SK, and VEGFD-SK, respectively. Inhibition of VEGFD-SK cell migration and invasion was detected by Transwell and wound healing assay. Then, lymphogenous metastatic model of ovarian cancer was established by injecting VEGFD-SK cells subcutaneously into the left hindlimb claw pad of nude mice. The inducted apoptotic effect of MP on VEGFD-SK cells were assessed by flow analysis and Hoechst-33258 staining, respectively, in vitro. The in vivo antitumor and antiangiogenic activities of MP gene were evaluated with lymphogenous metastatic model of ovarian cancer. Tumor volume and lymphatic metastasis rates were measured. Lymphatic vessels were delineated using Evan's blue and LYVE-1 staining. Expression of VEGF-D and MMP-2 were evaluated by immunostaining. Apoptosis of tumor cells was analyzed by Hoechst-33258 staining. Mice bearing VEGFD-SK tumor cells displayed more rapid tumorigenesis, higher lymphogenous metastatic tendency and increased lymphatic vessel density compared with the mice bearing WT-SK or EV-SK cells. However, VEGF-D-enhanced metastasis was evidently reversed by MP. MP significantly reduced the invasion of VEGFD-SK cells, tumor volume, lymphatic metastasis rates and lymphatic vessel density compared with control groups (P<0.05), accompanied with down-expression of VEGF-D and MMP-2 and increased apoptosis. Our data indicate that MP has strong antitumor and antimetastatic abilities, and it may be a promising therapeutic strategy against the lymphatic metastasis of human ovarian cancer.
An Evaluation of Mechanical Properties with the Hardness of Building Steel Structural Members for Reuse by NDT

The reuse system proposed by the authors is one method to reduce the environmental burden in the structural field. As for reusable members, we take up building steel structures used for plants and warehouses. These buildings are assumed to be demolished within approximately 30 years or more for physical, architectural, economic, or social reasons in Japan. In this paper, the performance of steel structural members of a gable frame is evaluated with a non-destructive test for reuse. First, the flow to estimate mechanical properties of steel structural members such as tensile strength, yield strength, and elongation is shown via a non-destructive test. Next, tensile strength, yield strength, and elongation of steel structural members are estimated, with hardness measured with a portable ultrasonic hardness tester. Finally, the mechanical properties of steel structural members for reuse are estimated based on the proposed flow.
On the vacuum oscillation solutions of the solar neutrino problem.

We study the stability of the two-neutrino vacuum oscillation solution of the solar neutrino problem with respect to changes of the total fluxes of $^{8}\mathrm{B}$ and $^{7}\mathrm{Be}$ neutrinos, ${\mathrm{\ensuremath{\Phi}}}_{\mathrm{B}}$ and ${\mathrm{\ensuremath{\Phi}}}_{\mathrm{Be}}$. For any value of ${\mathrm{\ensuremath{\Phi}}}_{\mathrm{Be}}$ from the interval 0.7${\mathrm{\ensuremath{\Phi}}}_{\mathrm{Be}}^{\mathrm{BP}}$\ensuremath{\le}${\mathrm{\ensuremath{\Phi}}}_{\mathrm{Be}}$\ensuremath{\le}1.3${\mathrm{\ensuremath{\Phi}}}_{\mathrm{Be}}^{\mathrm{BP}}$ the solar ${\ensuremath{\nu}}_{\mathit{e}}$ oscillations into an active neutrino, ${\ensuremath{\nu}}_{\mathit{e}}$\ensuremath{\leftrightarrows}${\ensuremath{\nu}}_{\mathrm{\ensuremath{\mu}}(\mathrm{\ensuremath{\tau}})}$, provide at 95% C.L. a description of the existing solar neutrino data for ${\mathrm{\ensuremath{\Phi}}}_{\mathrm{B}}$\ensuremath{\simeq}(0.35\char21{}3.4)${\mathrm{\ensuremath{\Phi}}}_{\mathrm{B}}^{\mathrm{BP}}$, ${\mathrm{\ensuremath{\Phi}}}_{\mathrm{B}}^{\mathrm{BP}}$ and ${\mathrm{\ensuremath{\Phi}}}_{\mathrm{Be}}^{\mathrm{BP}}$ being the fluxes in the solar model of Bahcall and Pinsonneault from 1992.

Long-Term Follow-up of HPV Infection Using Urine and Cervical Quantitative HPV DNA Testing

The link between infection with high-risk human papillomavirus (hrHPV) and cervical cancer has been clearly demonstrated. Virological end-points showing the absence of persistent HPV infection are now accepted as a way of monitoring the impact of prophylactic vaccination programs and therapeutic vaccine trials. This study investigated the use of urine samples, which can be collected by self-sampling at home, instead of cervical samples for follow-up of an HPV intervention trial. Eighteen initially HPV DNA-positive women participating in an HPV therapeutic vaccine trial were monitored during a three-year follow-up period. A total of 172 urine samples and 85 cervical samples were collected. We obtained a paired urine sample for each of the 85 cervical samples by recovering urine samples from six monthly gynaecological examinations. We performed a small pilot study in which the participating women used a urine collection device at home and returned their urine sample to the laboratory by mail. All samples were analyzed using quantitative real-time HPV DNA PCR. A good association (κ value of 0.65) was found between the presence of HPV DNA in urine and a subsequent cervical sample. Comparisons of the number of HPV DNA copies in urine and paired cervical samples revealed a significant Spearman rho of 0.676. This correlation was superior in women with severe lesions. The HPV DNA results of the small pilot study based on self-collected urine samples at home are consistent with previous and subsequent urine and/or cervical results. We demonstrated that urine sampling may be a valid alternative to cervical samples for the follow-up of HPV intervention trials or programs. The potential clinical value of urine viral load monitoring should be further investigated.
The Linear Algebra of the Sales Comparison Approach

This study presents the sales comparison approach to value as a system of linear algebra equations. The difference between appraiser and academician views of this system of equations is shown to pivot on the one-price assumption. The need of appraisers to subjectively derive adjustment factors is shown to be an artifact of the common practice of appraisers to assume multiple indicated values. The use of multiple regression analysis and other statistical techniques by academicians is shown to be possible only given the one-price assumption. Suggestions are presented for the improvement of both views.
Antidepressant Effects of Abscisic Acid Mediated by the Downregulation of Corticotrophin-Releasing Hormone Gene Expression in Rats

Background: Corticotrophin-releasing hormone (CRH) is considered to be the central driving force of the hypothalamic-pituitary-adrenal axis, which plays a key role in the stress response and depression. Clinical reports have suggested that excess retinoic acid (RA) is associated with depression. Abscisic acid (ABA) and RA are direct derivatives of carotenoids and share a similar molecular structure. Here, we proposed that ABA also plays a role in the regulation of CRH activity sharing with the RA signaling pathway. Methods: [3H]-ABA radioimmunoassay demonstrated that the hypothalamus of rats shows the highest concentration of ABA compared with the cortex and the hippocampus under basal conditions. Results: Under acute stress, ABA concentrations increased in the serum, but decreased in the hypothalamus and were accompanied by increased corticosterone in the serum and c-fos expression in the hypothalamus. Moreover, chronic ABA administration increased sucrose intake and decreased the mRNA expression of CRH and retinoic acid receptor alpha (RARα) in the hypothalamus of rats. Furthermore, ABA improved the symptom of chronic unpredictable mild stress in model rats, as indicated by increased sucrose intake, increased swimming in the forced swim test, and reduced mRNA expression of CRH and RARα in the rat hypothalamus. In vitro, CRH expression decreased after ABA treatment across different neural cells. In BE(2)-C cells, ABA inhibited a series of retinoid receptor expression, including RARα, a receptor that could facilitate CRH expression directly. Conclusions: These results suggest that ABA may play a role in the pathogenesis of depression by downregulating CRH mRNA expression shared with the RA signaling pathway.
Non-Intrusive Demand Monitoring and Load Identification for Energy Management Systems Based on Transient Feature Analyses

Energy management systems strive to use energy resources efficiently, save energy, and reduce carbon output. This study proposes transient feature analyses of the transient response time and transient energy on the power signatures of non-intrusive demand monitoring and load identification to detect the power demand and load operation. This study uses the wavelet transform (WT) of the time-frequency domain to analyze and detect the transient physical behavior of loads during the load identification. The experimental results show the transient response time and transient energy are better than the steady-state features to improve the recognition accuracy and reduces computation requirements in non-intrusive load monitoring (NILM) systems. The discrete wavelet transform (DWT) is more suitable than short-time Fourier transform (STFT) for transient load analyses.
Ets2-Dependent Stromal Regulation of Mouse Mammary Tumors

ABSTRACT The Ets2 transcription factor is regulated by mitogen-activated protein (MAP) kinase phosphorylation of a single threonine residue. We generated by gene targeting a single codon mutation in Ets2 substituting Ala for the critical Thr-72 phosphorylation site (Ets2A72 ), to investigate the importance of MAP kinase activation of Ets2 in embryo and tumor development. Ets2A72/A72 mice are viable and develop normally. However, combining the Ets2A72 allele with a deletion mutant of Ets2 results in lethality at E11.5 and shows that Ets2A72 is a hypomorphic allele. Mammary tumors caused by transgenic polyomavirus middle T antigen, activated Neu(Erbb2), or the combination of Neu and transgenic VEGF (Neu; VEGF-25) were all restricted in Ets2A72/A72 females. The Ets2A72/A72 restriction on Neu; VEGF-25 tumor growth was associated with increased p21Cip1 expression. The size of tumors transplanted into fat pads of mice with Ets2 targeted alleles was correlated directly with Ets2 activity and fewer stromal cells expressing matrix metalloproteinase 9 (MMP-9). Decreased MMP-3 and MMP-9 mRNAs were confirmed in Ets2A72/A72 macrophages. Activation of Ets2 at Thr-72 acts in the stroma, downstream of vascular endothelial growth factor production, in part through the regulation of macrophage proteases to support the progression of Neu- and polyomavirus middle-T-initiated mammary tumors.
Elective cesarean section on psychiatric indications - the phenomenon analysis, report of two cases and psychiatric clinical recommendations.

OBJECTIVES In Poland, no guidelines concerning the mode of delivery in patients with psychiatric disorders have so far been developed. The most common psychiatric diagnosis discussed in the Polish literature in the context of the indications for the elective caesarean section is tokophobia. It was confirmed in recent studies that intense fear of childbirth, requiring medical interventions is an important predictor of postpartum depression. Other studies have shown that emergency delivery causes long lasting posttraumatic stress disorder symptoms. The aim of this paper is to discuss the different mental disorders, which may determine psychiatric indications for elective CS. METHODS A literature review and analysis of two cases. Review of the literature was made via MEDLINE and based on such a keywords as: mental health, mode of delivery, caesarean section, psychiatric indications for CS. In the analysis, papers based on population studies and essential because of the potential clinical decisions concerning psychiatric indications for CS were taken into account first. RESULTS Psychiatric indications for the preferred type of delivery are determined individually. They are mainly based on the ability of the psychiatric patient to cooperate with obstetric staff during vaginal delivery. The second area of psychiatric indications is a strong fear of labour that results in the need for psychiatric consultation in the last trimester of pregnancy or the perinatal period. CONCLUSIONS Antenatal care of women with mental disorders requires close cooperation between the obstetricians and psychiatrists specialised in the mental disorders due to somatic state. Such cooperation should lead to preventing both obstetric and psychiatric complications during the pregnancy and labour in women experiencing symptoms of mental disorders.
