title: Flexural, Shear, and Punching Shear Capacity of Three 48-Year-Old Prestressed Lightweight Concrete Double-Tee Bridge Girders
Creators: name: Pettigrew, Christopher S.
Publisher: name: Utah State University
Year: 2014

description: The Icy Springs Bridge in Coalville, Utah carries 2nd South Street over the Weber River west of Interstate 80. The bridge is owned by Coalville City and was originally constructed in 1965 as a single-span 51-foot long bridge using prestressed concrete double-tee girders. In the fall of 2013 the original bridge was replaced with a new 80-foot long single span bridge using prestressed concrete decked bulb-tee girders. The original girders were salvaged and transported to the Systems, Materials, and Structural Health Lab (SMASH Lab) where a series of tests were performed to determine the total losses in the prestressing of the strands, the flexural and shear capacities of the girders, and the punching shear capacity of the reinforced concrete deck. The results of these tests were compared to the values calculated using methods outlined in the 2012 American Association of State Highway and Transportation Officials Load and Resistance Factor Design (AASHTO LRFD) Bridge Design Specifications, the current bridge design code used by most departments of transportation, and a finite element model using the computer program ANSYS. For the shear and punching shear test results, the AASHTO LRFD Bridge Design Specifications was conservative and was able to predict the type of failure that occurred. However, the tested flexural results were below the calculated flexural capacities using the AASHTO LRFD Bridge Design Specifications. A finite element model was created and calibrated to the test results for the various loading and support conditions. The actual tested material properties were compared to the material properties used in the finite element analyses to determine the difference between the actual girders and the theoretical models. Funding for this project was provided by the Utah Transportation Center.
The role of feedback in Malaysian ESL secondary school classrooms
Creators: name: Othman, WM
Publisher: name: University Of Tasmania

description: This study examined the role of oral corrective feedback in the context of ESL (English as a second language) in one Malaysian state. Recent studies have provided empirical evidence to support a positive role for feedback in students' second language development. However there has also been evidence that suggests that oral corrective feedback is used in only a limited way in the Malaysian context. In seeking to understand this limited use of oral corrective feedback, Malaysian teachers' views were gained and their classroom teaching behaviours were investigated. The students' views on oral corrective feedback were also gained, particularly in relation to their attitudes and feelings towards the oral corrective feedback used by their teachers. While most studies have only examined the teachers' perspective, it was a feature of the design of this study to also include the students' perspectives in order to provide a more comprehensive approach to understanding the limited use of oral corrective feedback in this context. The study data were gained from a mixed methods approach of surveys, semi-structured interviews and classroom observation sessions, collected over five months in 42 secondary schools in the state of Penang, Malaysia. Of the 172 lower secondary school English teachers who responded to the questionnaire, 6 also participated in the interviews and classroom observations. The students' survey was completed by 1843 lower secondary school students. The analysis of the qualitative data was based on a constructivist approach which utilised grounded theory and coded strategies by thematic analysis; the quantitative data were analysed using standard statistical analysis procedures (SPSS) to provide descriptive statistics of frequency distributions, median scores and Chi-square tests. The main finding from data on the teachers' perspective was that they shared similar views on issues related to the use of oral corrective feedback in classroom lessons. Interestingly, the choice of oral corrective feedback by the teachers in the observation sessions did not seem to depend on the student oral language error types, as previous studies had shown. However, there were some variations evident in the types of oral corrective feedback used for certain error types. A second main finding of the study was that students actually perceived oral corrective feedback positively. They felt positive attitudes and feelings towards the error correction received from their teachers and they were keen to receive more teacher correction. This study contributes to both the theory and practice of English teaching and learning within a lower secondary ESL classroom context. It has provided insights into how English teachers might attend more usefully to their students' English learning needs, particularly by extending their use of oral corrective feedback.

description: Ovarian cancer (OC) is the fifth most common female malignant tumor and the leading cause of cancer-related death in women worldwide. Epithelial ovarian cancer (EOC) is the predominant type of OC. Investigating the mechanism underlying tumorigenesis and progression of EOC is urgent. Our previous research has shown that long non-coding RNAs (lncRNAs) CDKN2A-AS1 is upregulated in EOC tissues and cells. Furthermore, we have predicted that CDKN2A-AS1 is associated with the bone morphogenetic protein (BMP)-SMAD signaling pathway, which is negatively regulated by the sclerostin domain containing 1 (SOSTDC1). Therefore, we conjecture that the CDKN2A-AS1 regulate BMP-SMAD signaling pathway via interacting with SOSTDC1, which need more investigation. Moreover, the functions of the BMP-SMAD signaling pathway and the SOSTDC1 on EOC are still unclear. Herein, we unearthed that CDKN2A-AS1, BMP2/4/7, SMAD1/5/9 and phosphorylation of SMAD1/5/9 (p-SMAD1/5/9) were upregulated in EOC tissues and cells, whereas SOSTDC1 was downregulated in EOC tissues and cells. We firstly demonstrated that CDKN2A-AS1 bound directly with the SOSTDC1. CDKN2A-AS1 downregulated the expression of SOSTDC1, but upregulated the expression of BMP2/4/7, SMAD1/5/9, and p-SMAD1/5/9. CDKN2A-AS1 promoted the proliferation, migration, invasion of EOC cells and tumor growth in vivo, whereas SOSTDC1 inhibited the proliferation, migration, invasion of EOC cells. Knockdown SOSTDC1 rescued the inhibitory effect of si-lncRNA CDKN2A-AS1 on the EOC cells proliferation, migration and invasion. These results demonstrated that CDKN2A-AS1activated the BMP-SMAD signaling pathway by directly bind with SOSTDC1 to promote EOC tumor growth. CDKN2A-AS1/SOSTDC1 axis may provide a novel therapeutic strategy for EOC treatment.

description: Consideration was given to a model of social dynamics controlled by successive collective decisions based on the threshold majority procedures. The current system state is characterized by the vector of participants' capitals (utilities). At each step, the voters can either retain their status quo or accept the proposal which is a vector of the algebraic increments in the capitals of the participants. In this version of the model, the vector is generated stochastically. Comparative utility of two social attitudes--egoism and collectivism--was analyzed. It was established that, except for some special cases, the collectivists have advantages, which makes realizable the following scenario: on the conditions of protecting the corporate interests, a group is created which is joined then by the egoists attracted by its achievements. At that, group egoism approaches altruism. Additionally, one of the considered variants of collectivism handicaps manipulation of voting by the organizers.

title: Five-Year Prospective Evaluation of the Development of Borderline Symptoms in Psychiatrically Hospitalized Adolescents Who Engage in Deliberate Self-Harm and Suicide-Related Behaviors
Creators: name: Homan, Kendra J.
Publisher: name: Utah State University
Year: 2014

description: Borderline personality disorder (BPD) is a form of psychopathology characterized by a pervasive pattern of instability with emotion regulation, impulse control, interpersonal relationships, and sense of self. While not a required diagnostic marker, the majority of individuals with BPD engage in some form of deliberate self-harm (e.g., suicide attempts, nonsuicidal self-injurious behavior) or suicide-related behavior (e.g., suicidal ideation, suicide threats). Longitudinal data from a sample of adolescent psychiatric inpatients who were hospitalized for deliberate self-harm and suicide-related behavior were followed for 5 years to investigate whether deliberate self-harm or suicide-related behaviors predicts BPD at 3-year follow-up and 5-year chart review. The extant data set consisted of 132 consecutively admitted adolescent psychiatric inpatients who completed a series of self-report questionnaires assessing deliberate self-harm and suicide-related behaviors, maladaptive familial behavior, peer victimization, and emotion regulation difficulties. Data regarding index psychiatric hospital admission diagnoses, childhood maltreatment, and BPD diagnoses were abstracted from the patient’s medical and psychiatric records and BPD was also assessed though a structured clinical interview. Suicide threats were the only variable found to be predictive of BPD at 5-year chart review. Other empirically (e.g., history of childhood maltreatment, maladaptive familial behavior, and peer victimization) and theoretically (e.g., emotion regulation difficulties) grounded constructs were also examined and were not found to be predictive of BPD in the current study. To our knowledge, this is the first study to investigate prospective associations between deliberate self-harm and suicide-related behaviors and BPD. Future directions and limitations of the research are discussed.

description: Non-trivial spatial topology of the Universe may give rise to potentially measurable signatures in the cosmic microwave background. We explore different machine learning approaches to classify harmonic-space realizations of the microwave background in the test case of Euclidean $E_1$ topology (the 3-torus) with a cubic fundamental domain of a size scale significantly smaller than the diameter of the last scattering surface. This is the first step toward developing a machine learning approach to classification of cosmic topology and likelihood-free inference of topological parameters. Different machine learning approaches are capable of classifying the harmonic-space realizations with accuracy greater than 99% if the topology scale is half of the diameter of the last-scattering surface and orientation of the topology is known. For distinguishing random rotations of these sky realizations from realizations of the covering space, the extreme gradient boosting classifier algorithm performs best with an accuracy of 88%. Slightly lower accuracies of 83% to 87% are obtained with the random forest classifier along with one- and two-dimensional convolutional neural networks. The techniques presented here can also accurately classify non-rotated cubic $E_1$ topology realizations with a topology scale slightly larger than the diameter of the last-scattering surface, if enough training data are provided. While information compressing methods like most machine learning approaches cannot exceed the statistical power of a likelihood-based approach that captures all available information, they potentially offer a computationally cheaper alternative. A principle challenge appears to be accounting for arbitrary orientations of a given topology, although this is also a significant hurdle for likelihood-based approaches.

title: A Case Study of Preservice Teachers in an Associate of Science Degree Early Childhood Teacher Education Program: Perceptions of Professional Preparation
Creators: name: Sermon, Tracy E.
Publisher: name: Utah State University
Year: 2014

description: The purpose of this study was to examine the perceptions of preservice students completing their associate’s degree (AS) in early childhood education (ECE). My intent was to discover, from the preservice teacher’s perspective, what skills and knowledge preservice students consider necessary to teach young children. I was also interested in how they viewed their professional preparation at the completion of their AS program.
The methods included participant interviews, documents and assignments completed by students, and program contextual data (faculty focus group and program documents). Seven themes were identified that represented the student’s perceptions of the skills and knowledge needed for working with young children (child development, learning environment, guidance, curriculum, teaching, assessment and experiences with children). All students reported the development of knowledge and skills through their participation in the ECE program. Each of these themes identified student support and belief in the philosophy of developmentally appropriate practices.
Three themes were identified that supported the overall perception of their professional development (reflection, National Association for the Education of Young Children [NAEYC] New Teacher Standards, becoming a professional). All preservice students identified development of professional skills, and reported increased confidence in their preparation to be early childhood classroom teachers. All identified NAEYC New Teacher Standards as part of their professional development and understanding.
This study provides the perspective of the AS degree seeking ECE preservice student. Little research is available on 2-year students. Further research in this area would aid in understanding and preparing teachers who are likely to work with the youngest in our society.

title: Conditioned Reinforcement and the Value of Praise in Children with Autism
Creators: name: Beus, Ben
Publisher: name: Utah State University
Year: 2014

description: Many efforts in teaching children with autism are focused on increasing the value of praise as a reward for work. Increasing the value of praise can help children with autism to work in a natural setting, without requiring constant rewards of food or toys for work. In this study, I analyzed a pairing method—a technique of providing verbal praise while simultaneously providing a food reward—to assess whether it would result in an increased value for praise for participants in the study. First, a baseline phase was conducted in which praise statements were provided as a reward for a certain task to see how quickly participants would engage in the task. In the next phase, a pairing condition was implemented in which participants were prompted to engage in the same task; food was provided along with praise as a reward for working on the given task. Finally, during the test phase, praise was again provided as the sole reward for the task, and I measured how quickly participants worked on the task to evaluate whether the value of praise had been increased. During the test phase two participants continued to engage in the task relatively quickly, suggesting that the value of praise had been increased for these two participants.

description: We study the effects of annealing on (Ga0.64,In0.36) (N0.045,As0.955) using hard X-ray photoelectron spectroscopy and X-ray absorption fine structure measurements. We observed surface oxidation and termination of the N-As bond defects caused by the annealing process. Specifically, we observed a characteristic chemical shift towards lower binding energies in the photoelectron spectra related to In. This phenomenon appears to be caused by the atomic arrangement, which produces increased In-N bond configurations within the matrix, as indicated by the X-ray absorption fine structure measurements. The reduction in the binding energies of group-III In, which occurs concomitantly with the atomic rearrangements of the matrix, causes the differences in the electronic properties of the system before and after annealing.

description: The purpose of this study was to quantitate the populations o f lymphocytes in the spleens and intestines of normal and immunosuppressed adult C57BL/6N mice that were noninfected or infected with Cryptosporidium parvum. This was accomplished by using the following methodologies: immunohistochemistry, ELISA-spot assay, and flow cytometry.
Mice in groups 1 and 2 were immunosuppressed, but only group 2 was infected. Mice in group 3 were only infected, whereas group 4 served as the normal control. Mice were immunosuppressed with dexamethasone (DEXI at a dosage of 125µg/mouse/day. Infected mice received 106 oocysts per os . The numbers o f lymphocytes were monitored from day 0 to day 18 postinfection. Flow cytometry using antibodies directed against CD4+ and CDS+ T cells (helper and cytotoxic, respectively) and B cells (expressing IgG, IgM, and IgA receptors) revealed that c. parvum did not evoke an alteration in the phenotypic profile of lymphocytes within spleens or Peyer's patches (PP) of mice in groups 2 and 3 that was statistically different from groups 1 and 4. Immunosuppressed mice (groups 1 and 2) had significantly fewer lymphocytes (bearing CD4+, IgG, IgM, and IgA receptors) within the spleen when compared with mice in groups 3 and 4 (P

description: Spin accumulation and spin precession in single-layer graphene are studied by non-local spin valve measurements at room temperature. The dependence of the non-local magnetoresistance on electrode spacing is investigated and the results indicate a spin diffusion length of ~1.6 microns and a spin injection/detection efficiency of 0.013. Electrical detection of the spin precession confirms that the non-local signal originates from spin injection and transport. Fitting of the Hanle spin precession data yields a spin relaxation time of ~84 ps and a spin diffusion length of ~1.5 microns, which is consistent with the value obtained through the spacing dependence.

description: We continue a previous work on the comparison between the post-Newtonian (PN) approximation and the gravitational self-force (SF) analysis of circular orbits in a Schwarzschild background. We show that the numerical SF data contain physical information corresponding to extremely high PN approximations. We find that knowing analytically determined appropriate PN parameters helps tremendously in allowing the numerical data to be used to obtain higher order PN coefficients. Using standard PN theory we compute analytically the leading 4PN and the next-to-leading 5PN logarithmic terms in the conservative part of the dynamics of a compact binary system. The numerical perturbative SF results support well the analytic PN calculations through first order in the mass ratio, and are used to accurately measure the 4PN and 5PN non-logarithmic coefficients in a particular gauge invariant observable. Furthermore we are able to give estimates of higher order contributions up to the 7PN level. We also confirm with high precision the value of the 3PN coefficient. This interplay between PN and SF efforts is important for the synthesis of template waveforms of extreme mass ratio inspirals to be analysed by the space-based gravitational wave instrument LISA. Our work will also have an impact on efforts that combine numerical results in a quantitative analytical framework so as to generate complete inspiral waveforms for the ground-based detection of gravitational waves by instruments such as LIGO and Virgo.

Influence of large oscillations on stability of simple surge tank
Creators: name: Wei, Jiin-Piau
Publisher: name: University of British Columbia
Year: 2011

description: This study investigates the stability of a simple surge tank operating in conjunction with a turbine. The turbine is assumed to be governed for constant power output or for constant gate opening, depending on whether the instantaneous head acting on the turbine is greater or smaller than the rated head. Early investigations on the stability of oscillations assumed that the governor on a turbine ensured constant power output. In practice, the governor on a turbine can maintain constant power output only when the oscillations remain above the rated head and the full-gate position is not reached. For this case, a computer study showed that results of the investigation are in close agreement with the results of several investigators. A revised form of the Thoma's formula for surge tank stability with oscillations of large amplitude is proposed. When the head during the maximum downsurge falls below the rated head of the turbine the constant gate opening condition must be considered. A computer program was developed to study the stability of oscillations of large amplitude under constant gate opening condition. The transient conditions for three cases of load demand with initial steady state discharge of zero, one quarter and one half of the final steady state discharge were studied. The graphical form of the results allows the prediction of surge tank stability for oscillations of large amplitude for a simple surge tank. The graphs for all three conditions show that an increase in the rated head has a stabilizing influence on surge tank oscillations.

description: We investigate a higher-order topological insulator (HOTI) under strong nonlinearity, focusing on the existence and stability of high-amplitude corner states, which can find applications in optics, acoustics, elastodynamics, and other wave-based systems. Our study centers on a breathing Kagome lattice composed of point masses and springs known to exhibit edge and corner states in its linear regime. By introducing onsite cubic nonlinearity, we analyze its impact on both edge and corner states. The nonlinear continuation of the corner state unveils stable high-amplitude corner states within the lattice, featuring non-zero displacements at even sites from the corner -- a characteristic absent in the linear limit. Interestingly, the nonlinear continuation of the edge state reveals its transformation into distinct families of high-amplitude corner states via two pitchfork bifurcations. While some states maintain stability, others become unstable through real instability and Neimark-Sacker bifurcation. These unstable corner states dissipate their energy into the edges and the bulk over an extended period, as corroborated by long-time dynamical simulations. Consequently, our study provides insights into achieving significant energy localization at the corners of HOTIs through various classes of nonlinear states.

title: Transcervical Versus Laparoscopic Insemination in Nulliparous and Multiparous Ewes After Estradiol Cypionate Treatment
Creators: name: Gage, Tami L.
Publisher: name: Utah State University
Year: 1994

description: The only practical method for artificially breeding ewes with frozen semen is laparoscopic insemination into the lumen of the uterine horn. Like all surgical procedures, however, laparoscopic artificial inseminatiom has limitations. The procedure requires surgical skill and costly equipment. Repeated passage of the laparoscope through the abdominal wall causes adhesions. Depositing frozen/thawed semen at the os cervix results in low conception rates. The inability to pass an insemination pipette through the cervix has prevented artificial insemination in sheep from becoming a standard breeding method as in the cattle industry. This study compared laparoscopic and transcervical methods of insemination in nulliparous ewes and transcervical insemination in multiparous ewes after estradiol cypionate treatment.
Forty nulliparous commercial-cross Rambouillet ewes were treated with pessaries containing fluorogesterone acetate to synchronize estrus. After 14 days, pessaries were removed and ewes were injected IM with 400 IU of pregnant mare serum gonadotropin (PMSG). Ewes were randomly divided into laparoscopic and transcervical treatment groups, 14 and 26 respectively. Ewes were inseminated with thawed semen (75x106 motile spermatozoa). Pregnancy rate with laparoscopic insemination was 85% (confirmed at 55 days with real-time ultrasound) .. With the transcervical method, the speculum could only be inserted into the vagina of five ewes and the insemination pipette could only be passed through the cervix in two ewes. The combined pregnancy rate for deep cervical and transcervical insemination was 40% at 55 days.
Forty multiparous commercial-cross Rambouillet ewes were synchronized as previously described. Ewes were randomly separated into a control and estradiol cypionate treatment group of 20 animals each. Within each group 10 ewes were inseminated with frozen/thawed Suffolk semen and 1 Owith Rambouillet semen. Ten ewes within each sire genotype were treated with 1 mg IM of estradiol cypionate 16 hours prior to insemination. Treated ewes were inseminated into the uterine body 90% of the time and non-treated ewes 95%. There was no significant difference in cervical passage between these groups.
Pregnancy rates for transcervical artificial insemination in the Suffolk genotype were 0.05% and 40% in the Rambouillet (pregnancy confirmed at 55 days by real-time ultrasound). Lambing rates for the Suffolk and Rambouillet groups were zero and 0.05%, respectively.
title: Property Tax Capitalization: Theory and Empirical Evidence
Creators: name: Lillywhite, Jay M.
Publisher: name: Utah State University
Year: 1994

description: In an environment of increasing government expenditures financed largely viii through taxes, including a relatively visible and large residential property tax, the issue of whether property taxes are capitalized into market values is increasingly important. Property tax capitalization is the reflection of property taxes in the value of real property. The capitalization of property tax does not necessarily pose a problem; rather, problems arise when homes identical to each other have different taxes and these differentials are then capitalized into market values. These capitalized tax differentials result in large capital gains and losses to owners of real estate.
This study (1) reviews existing economic theory and empirical evidence on the capitalization of property taxes, (2) develops a model of property valuation inclusive of tax effects, and (3) estimates the parameters of this model using a comprehensive data set of over 334 home sales in the Logan, Utah area. The empirical results include an estimate of the tax capitalization effect. Two closely related issues are also addressed in the study. They include: (I) changes in real estate prices, including a suggested method for measuring such change and (2) a study of property tax equity, including two specific measures of tax fairness.
The conclusions are (I) tax differentials are capitalized; (2) real estate prices in the study area increased approximately 10 percent per year from 1989 to 1992; and (3) there is significant variation in assessment ratios.

description: The influence of micromagnetic objects on the dynamic magnetic excitation in magnetic thin films is studied by imprinting periodic domain wall patterns through selective ion irradiation in exchange biased Ni81Fe 19/IrMn structures. For high domain wall densities an increased precessional frequency is achieved. The zero field resonance of the domain wall state hereby depends directly on the stripe period, showing a pronounced increase with decrease of domain wall spacing. With the abrupt annihilation of magnetic domain walls with an applied bias field a jump-like decrease in precessional frequency takes place. The experimental data and micromagnetic simulations prove that the characteristic collective dynamic mode for the domain wall configurations is attributed to strongly coupled tilted magnetization structure. This is evidenced by an overlapping Néel wall structure for the narrowly spaced imprinted antiparallel unidirectional anisotropy state. The controlled introduction of high density frozen-in micromagnetic objects is a novel way to control the dynamic magnetic properties of continuous magnetic thin films.

description: This paper discusses both the conditions under which resilience in areas of limited statehood (ALS) and contested orders (CO) can be fostered and the potential contributions by the EU and its member states. Drawing on EULISTCO’s conceptual framework, the paper defines the analytical category of resilience and provides a roadmap to study its characteristics in configurations of ALS and CO. In fact, it applies – and further problematizes – such concepts to the Eastern and Southern neighbourhood. It formulates a number of general hypotheses about how resilience can be fostered in these contexts, highlighting its historically contingent and context-specific nature, discussing how external actors could contribute in fostering resilience. These sets of hypotheses are meant to provide a roadmap for – and be tested in – subsequent EU-LISTCO empirical enquiries.

description: This policy paper focuses on impacts of global and diffuse risks on the EU and its neighbourhood regions. It provides a brief overview of six major risk categories that cover majority of global and diffuse risks and suggests their prioritization based on temporality, probability of occurrence and multiplication effect. The empirical evidence dictates that, in order to better cope with the impacts of global and diffuse risks and strengthen the resilience of its neighbourhood countries and with extension - of itself, the EU needs to prioritize the global risks which not only endanger the EU and its surroundings in the long term (climate change) but can also act as major spoilers in the short term (irregular migration & geopolitical rivalries). Finally, the EU should also pay attention to multiple effects of global risks and devise strategies based on regional and country-specific differentiation.

description: Strong coupling between electronic and mechanical degrees of freedom is a basic requirement for the operation of any nanoelectromechanical device. In this Review we consider such devices and in particular investigate the properties of small tunnel-junction nanostructures that contain a movable element in the form of a suspended nanowire. In these systems, electrical current and charge can be concentrated to small spatial volumes resulting in strong coupling between the mechanics and the charge transport. As a result, a variety of mesoscopic phenomena appear, which can be used for the transduction of electrical currents into mechanical operation. Here we will in particular consider nanoelectromechanical dynamics far from equilibrium and the effect of quantum coherence in both the electronic and mechanical degrees of freedom in the context of both normal and superconducting nanostructures.

description: This paper explores the extent to which global and diffuse risks impact the Eastern Partnership (EaP) countries of the EU’s Eastern neighbourhood and identifies tipping points at which risks can turn into immediate threats for the EaP countries, with implications for the EU. We apply five major risk categories to the EaP area that cover the majority of global and diffuse risks and suggest their prioritization based on temporality, probability of occurrence, and potential multiplication effects. We identify 28 tipping points which may exacerbate the impact of global and diffuse risks in EaP countries and result in governance breakdowns or new violent conflicts. The evidence suggests three global risks ‒ geopolitical rivalry, unconventional security risks and global economic and financial risk ‒ as most probable and with the most destabilizing impact on the EaP area in the short term. Disease outbreaks can be equally destructive, but with less certain probability. In terms of actorness, a majority of global risks seem to be linked to Russia and its assertive agenda, whereas others are diffuse in nature and hard to locate. Finally, in terms of resilience and mitigation of risks, societies in the EaP area seem to possess a basic degree of governance capacity which needs to be further strengthened by the EU to better cope with global and diffuse risks.
title: Evaluation of Milk Production in Western Whiteface and Navajo-Churro Ewes

description: Western Whiteface and Navajo-Churro Ewes, two types of sheep present in the Intermountain West, were compared for their milk production ability. Amount of milk produced per individual and the group milk composition were analyzed for butterfat, lactose, somatic cell count, protein, calcium, and phosphorous.
Ewes were fed ad libitum alfalfa hay and had access to free-choice grain while in the milking parlor. Lambs were weaned at 35 d of age and removed to another holding area and placed on creep feed . Ewes were milked for 90 d following the weaning of the lambs.
Western Whiteface ewes had a much higher milk production level than the Navajo- Churro ewes (P < 0.05). Western Whiteface ewes were almost double in their overall level of production versus the Navajo-Churro ewes. Half of the Western Whiteface ewes completed the 90-d lactation period, producing an average of . 83 kg of milk per day. Navajo-Churro ewes did not complete the full lactation period, with I 000/o of them ceasing milk production before completion of the 90-d milking period. The criterion for being considered dry consisted of completing six consecutive milkings while producing 50 ml or less of milk.
Overall production for the two groups of ewes was .83 kg/day of milk for the Western Whiteface ewes and .52 kg/day for the Navajo-Churro. The average number of days in production for the Western Whiteface ewes was 69.5 d and 50 d for the Navajo-Churro. Western Whiteface ewes consistently exhibited higher milk production levels than the Navajo- Churro ewes and they adapted well to the milking barn. Navajo-Churro ewes did not produce an adequate quantity of milk for a dairy setting.

description: In Egypt and Tunisia, where violent radicalization has increased in recent years, official religious institutions have been tasked by the governments with the mission of countering ‘deviant’ ideas by preaching ‘moderate’ Islam. In order for religious institutions to play a positive role in preventing violent radicalization, they should start by consolidating their status as legitimate religious actors independent of political authorities, and then compete with their ideas in a plural religious sphere, rather than impose them on Muslims as ‘the true Islam’. While the EU could encourage the political regimes in both countries to ensure the independence of these religious institutions, it should engage cautiously with state religious institutions so as to not unintentionally damage their legitimacy in the religious sphere.
Elucidating the roles of aurora B kinase in neurons

description: To reveal molecular determinates that underlie the intrinsic molecular pathways within neurons that support regeneration after injury, a DNA microarray study was performed on axotomized neuronal clusters that were maintained in culture and free from glial and astrocytes contamination. The microarray data indicated that post-injury regenerative sprouting requires two distinct pathways; a cell survival response to protect against pernicious secondary processes and a regenerative response driven by modulation of the neuronal cytoskeleton. From the transcriptomic data, cell cycle associated aurora B kinase (Aurkb), which was significantly up-regulated but never investigated in the context of neurons, was identified for further work. Immunohistochemical studies revealed that Aurkb is expressed extensively and cell-specifically in neurons of certain brain structures such as the cortex, hippocampus and amygdala. Its elevated expression in the embryonic brain cortex as compared to that of an adult implies that it may be involved in the process of brain maturation. Interestingly, the changing localization of Aurkb within developing cultured neurons and particularly its localisation outside of the nucleus at various stages of neuronal maturation further suggests that it may have direct roles neurite outgrowth. Indeed, impairing Aurkb activity in cultured neurons via different experimental approaches resulted in several key neuronal deficits. Generally, neurons with inactive Aurkb were found to have either shorter or no elaborated axons. They also possessed abnormally swollen cell bodies. Enlargement of the cell body, independent of nucleus size, was related to a substantial increase in microtubule mass within the area between the nucleus and axon hillock region. Furthermore, their expanded cell bodies are bordered by several aberrant, thin, frayed and highly disorganised neuritic processes. Next, yeast 2 hybrid identified INCENP as a binding partner of Aurkb in neurons. Subsequent phosphoproteomics studies coupled with functional analysis of protein associations have further revealed that inhibition of neuronal Aurkb affected a cluster of proteins and kinases that are major players of neuronal cytoskeleton regulation and organisation. In conclusion, this is the first comprehensive study of Aurkb in the brain and neurons. Specifically, the phosphoproteomic, pharmacological and molecular knockin and knockout studies provided considerable evidence that Aurkb has key roles in neurite cytoskeleton modulation. Taken together, the work in this thesis has clearly identified a novel and alternate cell cycle independent function of Aurkb in post-mitotic neurons.

description: In situ morphological investigation of the {105} faceted Ge islands on the Si(001) surface (hut clusters) have been carried out using an ultra high vacuum instrument integrating a high resolution scanning tunnelling microscope and a molecular beam epitaxy vessel. Both species of hut clusters--pyramids and wedges--were found to have the same structure of the {105} facets which was visualized. Structures of vertexes of the pyramidal clusters and ridges of the wedge-shaped clusters were revealed as well and found to be different. This allowed us to propose a crystallographic model of the {105} facets as well as models of the atomic structure of both species of the hut clusters. An inference is made that transitions between the cluster shapes are impossible.
