Path-Space Information Bounds for Uncertainty Quantification and Sensitivity Analysis of Stochastic Dynamics

Uncertainty quantification is a primary challenge for reliable modeling and simulation of complex stochastic dynamics. Such problems are typically plagued with incomplete information that may enter as uncertainty in the model parameters, or even in the model itself. Furthermore, due to their dynamic nature, we need to assess the impact of these uncertainties on the transient and long-time behavior of the stochastic models and derive corresponding uncertainty bounds for observables of interest. A special class of such challenges is parametric uncertainties in the model and in particular sensitivity analysis along with the corresponding sensitivity bounds for stochastic dynamics. Moreover, sensitivity analysis can be further complicated in models with a high number of parameters that render straightforward approaches, such as gradient methods, impractical. In this paper, we derive uncertainty and sensitivity bounds for path-space observables of stochastic dynamics in terms of new goal-oriented divergences; the latter incorporate both observables and information theory objects such as the relative entropy rate. These bounds are tight, depend on the variance of the particular observable and are computable through Monte Carlo simulation. In the case of sensitivity analysis, the derived sensitivity bounds rely on the path Fisher Information Matrix, hence they depend only on local dynamics and are gradient-free. These features allow for computationally efficient implementation in systems with a high number of parameters, e.g., complex reaction networks and molecular simulations.
Learning Mathematics in English at Basic Schools in Ghana: A Benefit or Hindrance?.

Facilitating effective mathematics learning and higher mathematics achievement have long been recognized as a key to the scientific and technological advancement of the African continent. While the central role that language proficiency plays in mathematics teaching and learning has received an overwhelming research attention in the literature over the past two decades, this is not the case among African policy-makers and political leaders. Drawing mainly from our professional experiences as mathematics educators and from the international research literature, our primary intent in this paper is to answer this question: How does the learning of mathematics in English at the basic school level help or hinder students’ mathematical proficiency? To answer this question, the paper is organized as follows. The first part, the introduction, gives a brief overview of the language of learning and teaching in Africa. The second part describes the method and conceptual framework undergirding the research. In the third section, we have analyzed the effects of mathematics learning and teaching through English for basic students whose mother tongue is a Ghanaian language. The conclusion offers four recommendations for developing and improving the mathematics proficiency of students in basic schools.

Optimal estimation of the mean function based on discretely sampled functional data: Phase transition

The problem of estimating the mean of random functions based on discretely sampled data arises naturally in functional data analysis. In this paper, we study optimal estimation of the mean function under both common and independent designs. Minimax rates of convergence are established and easily implementable rate-optimal estimators are introduced. The analysis reveals interesting and different phase transition phenomena in the two cases. Under the common design, the sampling frequency solely determines the optimal rate of convergence when it is relatively small and the sampling frequency has no effect on the optimal rate when it is large. On the other hand, under the independent design, the optimal rate of convergence is determined jointly by the sampling frequency and the number of curves when the sampling frequency is relatively small. When it is large, the sampling frequency has no effect on the optimal rate. Another interesting contrast between the two settings is that smoothing is necessary under the independent design, while, somewhat surprisingly, it is not essential under the common design.
CHAPTER 6 TEACHING AND LEARNING WITH THREE- DIMENSIONAL REPRESENTATIONS

Computer-based visualizations play a profoundly important role in chemistry instruction. In this chapter, we review the role of visualization tools and possible ways in which they may influence thinking about chemistry. There are now several visualization systems available that allow students to manipulate important variables in obtain a solution to a scientific problem. We discuss the fundamental differences between these tools, and we emphasize the use of each within the context of constructivist curricula and pedagogies. We also consider the impact such tools may have on visuo-spatial thinking. We suggest that although visuo-spatial ability may be important in visualization use, its role has at times been overemphasized. We argue for a more nuanced, richer understanding of the many ways in which visuo- spatial reasoning is used in solving chemistry problems. This discussion leads to a set of design principles for the use of visualization tools in teaching chemistry. Finally, we present our work on the Kinemage Authorship Project, a program designed to assist students in understanding spatial structures in complex, biochemical molecules. The Kinemage Authorship Project allows students to construct their own molecular visualizations, and we discuss how this may lead to greater understanding of the spatial properties of molecules. This constructivist program embodies many of the design principles that we present earlier in the chapter.
On Cores and Ewmsibility*

An economic model of trading in commodities that are inherently indivisible, like houses, is investigated from a game-theoretic point of view. The concepts of balanced game and core are developed, and a general theorem of Scarf’s is applied to prove that the market in question has a nonempty core, that is, at least one outcome that no subset of traders can improve upon. A number of examples are discussed, and the final section reviews a series of other models involving indivisible commodities, with references to the literature.
Csr: Medium: Collaborative Research: Architecture and System Support for Power-agile Computing

As energy management on energy-constrained devices continues to challenge researchers and frustrate users, device designs are addressing the problem by integrating more hardware components that can trade off energy and performance. Dynamic voltage-and-frequency scaling (DVFS) allows CPUs and memory to trade off speed and energy, buffering and polling rates allow radios to trade off latency and energy, and screen refresh rates allow displays to trade off quality and energy. And as the Dark Silicon utilization wall forces systems to choose what parts of the CPU to operate, the already-large configuration space will explode. This proposal refers to the emerging class of devices integrating multiple energy-proportional components as power-agile, reflecting their potential ability to adaptively reallocate energy usage between components to improve performance and save energy. But as energy-management features proliferate, new interfaces enabling coordination between applications, the operating system (OS), and hardware are urgently needed to realize the potential energy and performance benefits.
Entropy and periodic points for transitive maps

The aim of this paper is to investigate the connection between transitivity, density of the set of periodic points and topological entropy for low dimensional continuous maps. The paper deals with this problem in the case of the n–star and the circle among the one–dimensional spaces and in some higher dimensional spaces. Particular attention is paid to triangular maps and to extensions of transitive maps to higher dimensions without increasing topological entropy.
The Sequencing of Basic Chemistry Topics by Physical Science Teachers

The purpose of this study was to find out teachers’ preferred teaching sequence for basic chemistry topics in Physical Science in South Africa, to obtain their reasons underpinning their preferred sequence, and to compare these sequences with the prescribed sequences in the current curriculum. The study was located within a pragmatic paradigm and employed a multi-level learning model as an interpretive framework. A mixed-methods research design was used and survey data collected from a convenience sample of 227 physical science teachers and follow-up interviews with a subset of 11 experienced teachers. Analysis of the data revealed that in general 70% of teachers preferred sequences starting with microscopic-level knowledge such as atoms and molecules, while only 30% preferred starting with macroscopic-level knowledge topics such as solids, liquids and gases. Five main categories of reason were given by teachers. The majority of teachers’ reasons focused on general learning principles such as moving from simple to complex or linking to prior knowledge as opposed to focusing on the specific needs and demands of chemistry knowledge. In addition, it was found that the new Curriculum Assessment Policy Statement was based on starting with macroscopic-level topics which indicates a potential conflict between teachers’ preferred sequences and those required by the current curriculum.
Developing talent among young dancers: findings from the UK Centres for Advanced Training

The identification and development of talent is a key concern for many dance educators, yet little research has been conducted in the area. In order to understand better how to optimise dance talent development among young people, systematic and rigorous research is needed. This paper summarises and discusses the key findings of a ground-breaking longitudinal interdisciplinary research project into dance talent development. Over two years, almost 800 young dancers enrolled at one of the eight nationwide Centres for Advanced Training (CATs) participated in the project. Physical factors, psychological characteristics, and injury data were collected quantitatively while the students' thoughts and perspectives on commitment, creativity and cultural variables were captured using qualitative methods. The largest study of its kind, the project yielded a wide range of findings with a number of practical implications. The main focus of this paper is on how the project findings apply to important pedagogic topics such as audition criteria, passion and commitment, and teaching behaviour. The area of talent identification and development is complex, yet this research has begun to shed new light on the notion of talent and has provided novel insights to support its development.
HAPTEN-SPECIFIC IgE ANTIBODY RESPONSES IN MICE

The present studies have established conditions for the demonstration of cooperative interactions between specific T and B lymphocyte populations in the development of IgE antibody responses in vivo in mice. This has been accomplished by utilizing a system which permits the successful adoptive transfer to irradiated recipients of DNP-specific secondary IgE responses with spleen cells from suitably primed syngeneic donor mice. Thus, adoptively transferred DNP-KLH or DNP-ASC-primed spleen cells produced high levels of anti-DNP antibodies of both IgE and IgG antibody classes in response to challenge with the appropriate homologous priming conjugate but failed to develop more than meager responses to the reciprocal heterologous conjugate. However, when spleen cells from donors primed to the second carrier were concomitantly transferred with hapten-primed lymphocytes, secondary IgE ant-DNP responses were consistently obtained upon challenge with the heterologous conjugate. Moreover, we have been able to elicit augmented primary IgE anti-DNP antibody responses to either DNP-ASC or DNP-KLH after adoptive transfer of spleen cells from donors primed only to the carrier, ASC or KLH, respectively. This adoptive transfer system has enabled us to provide direct proof for the participation of θ-bearing T lymphocytes in antibody responses of the IgE class. Thus, the capacity of ASC-primed spleen cells to effectively cooperate with the DNP-KLH-primed lymphocytes in the adoptive secondary response to DNP-ASC could be abolished by in vitro treatment of such cells with anti-θ serum plus complement. This was true not only for the anti-DNP response of the IgG antibody class, but for the IgE antibody class as well. These studies have, furthermore, demonstrated the capacity to stimulate secondary anti-DNP antibody production in vivo by the concomitant administration of the DNP and relevant carrier determinants on separate molecules. This was more readily seen in the IgE than in the IgG antibody class. Thus, DNP-ASC-primed cells developed significant IgE, but more variable IgG, anti-DNP responses upon challenge with DNP-KLH plus unconjugated ASC. Antibody responses of both classes elicited in this manner were appreciably improved by the transfer of additional carrier (ASC)-primed cells. These and other results presented herein suggest that IgE B lymphocyte precursors may be inherently more sensitive than IgG B cells to at least certain of the functions of T lymphocytes concerned with regulatory mechanisms involved in antibody production.
Evaluating student's satisfaction of using social media through collaborative learning in higher education

Social media have permeated all generations of Internet users, becoming a prominent communications tool and found to be facilitating teaching and learning, particularly in the student community. Thus, academic institutions and faculty are increasingly using social networking sites, such as Facebook and LinkedIn, to connect with students and to deliver instructional content. This has led to a rise in questions about the impact of social media for collaborative learning and the possibility of using it as an effective teaching tool. To learn more about the student' satisfaction with social media usage for collaborative learning improvement between students, we conducted a survey in a typical university in Malaysia. Basic aim of this research is to identify the characteristics and factors surrounding the usability of the social media for collaborative learning in higher education. A total of 134 Universiti Teknologi Malaysia (UTM) students were used in the survey. We development a conceptual framework in which we propose that interactive with peers and teachers, engagement, perceived ease of use and perceived usefulness ;that explain the positive effects and benefits of using social media to enhancing student learning through collaborative learning which, in turn, improves student academic performance. The results revealed a statistically significant negative relationship between perceived usefulness and their satisfaction. Further, engagement and perceived ease of use was found to be highly correlated with students' satisfaction for using social media for collaborative learning among students.
Induction of apoptosis in primary culture of rat hepatocytes by protease inhibitors

There is growing evidence that suggests the involvement of intracellular proteases in the process of apoptosis or programmed cell death. In this study, we have demonstrated that leupeptin, a cysteine protease inhibitor, can significantly increase the incidence of both apoptotic nuclear morphology change and internucleosomal DNA fragmentation in primary cultured hepatocytes in the absence of known apoptotic stimuli for hepatocytes. On the other hand, aspartic and serine protease inhibitors showed little or no effects on the apoptotic changes. In addition, we found that the apoptotic changes could be induced by chloroquine, an inhibitor of lysosomal proteolysis, but could not be induced by calpain inhibitors. These data suggest that inhibition of lysosomal cysteine proteases may induce apoptosis in primary cultured hepatocytes.
* 1 Ubrajhesl §

We suggest a possible explanation for cross-country differences in total factor productivity. Many technologies used by LDCs are developed in OECD economies, and as such, are designed to make optimal use of the skills of these richer countries' workforces. Due to differences in the supply of skills, some of the tasks performed by skilled workers in richer economies will be carried out by unskilled workers in the LDCs. Since the technologies in these tasks are designed to be used by skilled workers, productivity in LDCs will be low. Even when all countries have equal access to new technologies, this mismatch between skills and technology can lead to sizable differences in total factor productivity, in the order of 40 to 70 percent of the variation we observe in the data. Our theory also suggests that the trade regime and the degree of intellectual property right enforcement in LDCs have an important effect on the type of technologies developed in richer economies and on productivity differences.

MONETARY ANALYSIS: PRICE AND FINANCIAL STABIILTY 1

In a world with self-generated, endogenous risk and time-varying risk premia, price stability and financial stability are inseparable. A monetary analysis based on the distribution of liquidity mismatch across sectors provides valuable information about the build-up of vulnerabilities in tranquil times and helps to identify balance sheet impaired sectors in volatile times. When the monetary transmission mechanism becomes “sectorally impaired”, monetary policy action disproportionally favours issuers of government and large corporation debt over small and median enterprises (SMEs). Reviving a prudently designed asset backed securitization market for SME and consumer loans would alleviate this discrepancy and establish a pan European intermediation market.
INVESTIGATING DISCOURSE MARKERS IN PEDAGOGICAL SETTINGS: A LITERATURE REVIEW

This article discusses previous studies on discourse markers and raises research attention on discourse markers in pedagogical settings, especially in teacher talk. As important interactional features, discourse markers perform great multifunctionality in conversation. It is discovered that due to different research perspectives, there has always been confusion and disagreement in the terminology and analysis. Studies on discourse markers also often focus less on the local context. In classroom discourse, most related researches are limited to second language learners. Hence it is important to conduct a research on discourse markers in teacher talk and explore their functions in classroom interaction. The review suggests that a multi-functional framework should be applied in relation to pedagogical purposes.
The strong Kervaire invariant problem in dimension 62

Using a Toda bracket computation $\langle \theta_4, 2, \sigma^2\rangle$ due to Daniel C. Isaksen [11], we investigate the $45$-stem more thoroughly. We prove that $\theta_4^2=0$ using a $4$-fold Toda bracket. By [2], this implies that $\theta_5$ exists and there exists a $\theta_5$ such that $2\theta_5=0$. Based on $\theta_4^2=0$, we simplify significantly the $9$-cell complex construction in [1] to a $4$-cell complex, which leads to another proof that $\theta_5$ exists.
The Capability of Spatial Analysis in Planningthe Accessibility for Hazard Community fromDebris-Flow Events

Debris flow is a destructive disaster causing tragic loss and damages to vulnerable people and their properties in many regions around the world. According an impact of this disaster, hazard areas are submerged in mud and debris causing enormous difficulties to all relevant organisations and affected people to access over the hazard community. Although an inaccessibility is one of the major problems considered to be solved in an urgent stage, the lack of a comprehensive study in activities of involved people through time line since the disaster occurrence causes a difficulty to plan the feasible solution to overcome those problems effectively. Therefore, this paper presents the existing knowledge in several activities related to accessibilities in hazard areas. Additionally, the initial findings derived from interviews conducted as a part of a doctoral research are determined showing real activities related to accessibilities in a study area of Thailand where was attacked by a major debris-flow event in 2001. Regarding the explored acitivities, this study aims to introduce a potential solution to overcome the inaccessibility problems in hazard areas by applying spatial analysis techniques. This solution presents a new method of an optimum balance between the explored problems from the interviews of affected people and the practices conducted by the local government to solve the inaccessibility in the hazard area. Some suggestions are addressed at the end of the paper to propose some additional practices with some considered factors for the spatial database design.
