Interactive generation of integrated schemas

Schema integration is the problem of creating a unified target schema based on a set of existing source schemas that relate to each other via specified correspondences. The unified schema gives a standard representation of the data, thus offering a way to deal with the heterogeneity in the sources. In this paper, we develop a method and a design tool that provide: 1) adaptive enumeration of multiple interesting integrated schemas, and 2) easy-to-use capabilities for refining the enumerated schemas via user interaction. Our method is a departure from previous approaches to schema integration, which do not offer a systematic exploration of the possible integrated schemas. The method operates at a logical level, where we recast each source schema into a graph of concepts with Has-A relationships. We then identify matching concepts in different graphs by taking into account the correspondences between their attributes. For every pair of matching concepts, we have two choices: merge them into one integrated concept or keep them as separate concepts. We develop an algorithm that can systematically output, without duplication, all possible integrated schemas resulting from the previous choices. For each integrated schema, the algorithm also generates a mapping from the source schemas to the integrated schema that has precise information-preserving properties. Furthermore, we avoid a full enumeration, by allowing users to specify constraints on the merging process, based on the schemas produced so far. These constraints are then incorporated in the enumeration of the subsequent schemas. The result is an adaptive and interactive enumeration method that significantly reduces the space of alternative schemas, and facilitates the selection of the final integrated schema.
Process variation aware OPC with variational lithography modeling

Optical proximity correction (OPC) is one of the most widely used resolution enhancement techniques (RET) in nanometer designs to improve subwavelength printability. Conventional model-based OPC assumes nominal process parameters without considering process variations, due to prohibitive runtimes of lithography simulations across process windows. This is the first paper to propose a true process-variation aware OPC (PV-OPC) framework. It is enabled by the variational lithography modeling and guided by the variational edge placement error (V-EPE) metrics. Due to the analytical nature of our models, our PV-OPC is only about 2-3 times slower than the conventional OPC, but it explicitly considers the two main sources of process variations (dosage and focus) during OPC. Thus our post PV-OPC results are much more robust than the conventional OPC ones, in terms of both geometric printability and electrical characterization under process variations
Prevalence of Vibrio cholerae in rivers of Mpumalanga province , South Africa as revealed by polyphasic characterization

Cholera is a life-threatening diarrhoeal disease, which mainly affects inhabitants of developing countries due to poor socio-economic conditions and lack of access to potable water and sanitation. Toxigenic Vibrio cholerae are the aetiological agents of cholera. These bacteria are autochthonous to aquatic environments, hence water plays a central role both in the epidemiology and transmission of cholera. The aim of this study was to determine the prevalence of V. cholerae from 32 sites of major rivers in Mpumalanga province of South Africa using a polyphasic approach. Water samples (594) collected over for 4 months were cultured on thiosulphate-citrate-bile salt-sucrose agar, and oxidase positive (88) isolates were subjected to biochemical tests and duplex polymerase chain reaction targeting the outer membrane protein (ompW) and cholera toxin (ctxAB) genes. All ompW PCR positive V. cholerae isolates were subjected to rfbO1 PCR. Fifteen isolates from Crocodile, Komati and Gutshwa rivers were assigned to V. cholerae by both biochemical tests and PCR, of which no isolates were positive for ctxAB and rfbO1 genes. The polyphasic approach was effective at revealing non-O1 and non-toxigenic V. cholerae in some rivers. Such information is important for raising awareness regarding the presence of V. cholerae so that precautionary measures are taken on time.
Assessing Inheritance of Zircon and Monazite in Granitic Rocks from the Monashee Complex, Canadian Cordillera

Zircon and monazite from granitic sheets and dikes in the Monashee complex, Canadian Cordillera, were investigated to determine whether igneous crystallization occurred at 1� 9G a or 50 Ma with 1� 9 Ga inherited zircon and monazite. Four of the five samples are weakly deformed to undeformed, despite occurring in a gneiss dome at the structurally deepest exposed level of the orogen that elsewhere was strongly deformed and partly melted at 50 Ma. Based on U^(Th)^Pb ages from zircon and monazite, field relationships, and mineral composition and zoning, we conclude that the granitic rocks crystallized at 1� 9 Ga and were metamorphosed at 50 Ma. All dated zircon is 1� 9 Ga (except for 2� 3^2� 0G a inherited cores) and 1� 9 Ga monazite makes up 490% of the population in four samples. The remainder of the monazite is 50 Ma and all monazite in one sample is 50 Ma. Composition and zoning of 1� 9 Ga zircon and monazite are uniform within samples, yet differ between samples, indicating growth from 1� 9 Ga magmas that are unique to each sample. This relationship is unlikely if the grains are inherited because the host rocks are heterogeneous 2� 3^2� 1 Ga gneisses. The 1� 9 Ga zircon and monazite have zoning that is consistent with growth from magmas, whereas the 50 Ma monazite has variable composition and zoning that suggest growth from diverse metamorphic fluids. The results demonstrate that part of the Monashee complex was last strongly deformed and partly melted at 1� 9 Ga, and thus largely escaped Cordilleran tectonism.
Multiple concomitant positive patch test reactions

Thirty‐five patients who showed 90 one plus (+) patch test reactions to 28 patch test chemicals at Day 2 (D2) were retested to the chemicals at D7. On retesting, 60 % (54/90) reactions were positive but 42 % (38/90) were negative at D9, suggesting that false positive patch test reactions were common when more than one positive reaction was obtained by concomitant patch testing. On retesting, the total % positivity was reduced from 344 to 241 suggesting that the true index of sensitivity was falsely exaggerated by concomitant testing.
Discrimination Processes and Shifts in Carboxylation during the Phases of Crassulacean Acid Metabolism

The magnitude and extent of Crassulacean acid metabolism (CAM) activity in two Clusia species was manipulated to investigate the regulation of the distinct CAM phases. First, in response to leaf-air vapor pressure deficit at night, changes in leaf conductance altered on-line carbon-isotope discrimination throughout the theoretical range for dark CO2 uptake during CAM. These ranged from the limit set by phosphoenolpyruvate carboxylase (PEPc) (-6[per mille (thousand) sign], [delta]13C equivalent of -2[per mille (thousand) sign]) to that imposed by diffusion limitation (+4[per mille (thousand) sign], [delta]13C equivalent of -12[per mille (thousand) sign]), but the lowest carbon-isotope discrimination occurred when P[square root]pa was only 0.7. Second, when the availability of external or internal sources of CO2 was reduced for both field- and greenhouse-grown plants, CO2 uptake by day via PEPc during phase II largely compensated. Third, by reducing the dark period, plants accumulated low levels of acidity, and CO2 uptake occurred throughout the subsequent light period. Discrimination switched from being dominated by PEPc (phase II) to ribulose 1,5-bisphosphate carboxylase/oxygenase (phase III), with both enzymes active during phase IV. Under natural conditions, photochemical stability is maintained by extended PEPc activity in phase II, which enhances acid accumulation and delays decarboxylation until temperature and light stress are maximal at midday.
Relationship between power and sprint freestyle swimming.

In an effort to determine the role played by power in sprint swimming, 40 competitive swimmers (22 females and 18 males) were tested for arm power at velocities ranging from 1.60-3.28 m . s-1 using an apparatus that was specifically designed to mimic the arm action during swimming. Measurements were also made to determine the contribution of fatigability to spring swimming performance. In addition, each swimmer performed a series of 25-yd (22.86 m) freestyle sprints. A close relationship was found between power output and sprint swimming performance (r = 0.90). The highest power recordings were obtained at test velocities of 2.05 and 2.66 m . s-1, with the average velocity required for peak power being 2.40 m . s-1. This point is referred to as the optimal velocity. Four detrained swimmers were tested before and after 4 wk of isokinetic strength training only. On the average, performance improved 3.76%, while arm power increased by 18.66%. The fatigability of the competitive swimmers was not related to their sprint ability (r = 0.01). It is concluded that power, as measured in this study, offers an objective assessment of a component essential for success in sprint swimming.
Providing supportive care to cancer patients: a study on inter-organizational relationships

Abstract Background Supportive cancer care (SCC) has historically been provided by organizations that work independently and possess limited inter-organizational coordination. Despite the recognition that SCC services must be better coordinated, little research has been done to examine inter-organizational relationships that would enable this goal. Objective The purpose of this study was to describe relationships among programs that support those affected by cancer. Through this description the study objective was to identify the optimal approach to coordinating SCC in the community. Methods Senior administrators in programs that provided care to persons and their families living with or affected by cancer participated in a personal interview. Setting: South-central Ontario, Canada. Study population: administrators from 43 (97%) eligible programs consented to participate in the study. Results Network analysis revealed a diffuse system where centralization was greater in operational than administrative activities. A greater number of provider cliques were present at the operational level than the administrative level. Respondents identified several priorities to improve the coordination of cancer care in the community including: improving standards of care; establishing a regional coordinating body; increasing resources; and improving communication between programs. Conclusion Our results point to the importance of developing a better understanding on the types of relationships that exist among service programs if effective integrated models of care are to be developed.
SOCIAL IDENTITY IN PUERTO RICO

Abstract This study examines the social identity of 384 high school students from four age levels (10, 12, 15 and 17 years-old) in Puerto Rico. This complex society represents an interesting context because of the potential relevance of a number of dimensions for identity including language, cultural heritage, economic status, religion and political beliefs. An important methodological refinement is introduced in order to permit simultaneous examination of these various dimensions in terms of Puerto Rican identity. Three major dimensions of the students' social identity emerged from multidimensional scaling analyses and these were seen to contrast with previous research on ethnic identity in Canada, the United States and Wales.
Evaluation of different methods for detecting methicillin resistance in Staphylococcus aureus isolates in a university hospital located in the Northeast of Brazil

Many methods have been described for the detection of methicillin-resistant Staphylococcus aureus (MRSA), but the heterogeneous expression of methicillin resistance affects the reliability of these methods. The aim of the present study was to evaluate some methods for detecting methicillin resistance in Staphylococcus aureus isolates in a university hospital located in the Northeast of Brazil. Among the isolates, 15 were methicillin-susceptible and 45 were methicillin-resistant, including low-level heterogeneous resistance strains. Both the 30 ηg-cefoxitin disk and PBP2a test had 100% sensibility/specificity and appear to be good options for the detection of MRSA in the clinical laboratory.
The Courage to Teach: Exploring the Inner Landscape of a Teacher's Life.

The book ‘The Courage to Teach: Exploring the Inner Landscape of a Teacher's Life,’ by Parker Palmer, offers a much needed perspective on the task of management education. While explaining why teaching is avoided or, even worse, evaded, the book also holds out a promise: teaching from, and toward, wholeness can be a source of joy, distinct from but complementary to the joys of research. In some ways this book suggests that the time might be right for more study on the challenges of excellence in management education. A resource-based view has been applied to the firm; perhaps now is the time for considering its implications for the classroom.
Apolipoprotein A1 as a novel anti-implantation biomarker in polycystic ovary syndrome: A case-control study

Background: Women with polycystic ovary syndrome have lower pregnancy rates, possibly due to the decreased uterine receptivity. Successful implantation depends on protein networks that are essential for cross-talk between the embryo and endometrium. Apolipoprotein A1 has been proposed as a putative anti-implantation factor. In this study, we evaluated apolipoprotein A1 expression in human endometrial tissues. Materials and Methods: Endometrial apolipoprotein A1 messenger RNA (mRNA) and protein expression were investigated using quantitative real-time polymerase chain reaction (PCR) and Western blot. The distribution of apolipoprotein A1 was also detected by immunostaining. Samples were obtained from 10 patients with polycystic ovary syndrome and 15 healthy fertile women in the proliferative (on day 2 or day 3 before ovulation, n = 7) and secretory (on days 3-5 after ovulation, n = 8) phases. Results: Endometrial apolipoprotein A1 expression was upregulated in patients with polycystic ovary syndrome compared to normal subjects. However, apolipoprotein A1 expression in the proliferative phase was significantly higher than in the luteal phase (P value < 0.05). Conclusion: It seems that differentially expressed apolipoprotein A1 negatively affects endometrial receptivity in patients with polycystic ovary syndrome. The results showed that apolipoprotein A1 level significantly changes in the human endometrium during the menstrual cycle with minimum expression in the secretory phase, coincident with the receptive phase (window of implantation). Further studies are required to clarify the clinical application of this protein.
Sex Differences in Response to Evaluative Feedback: A Field Study

We investigated sex differences in response to evaluative feedback among bank employees who were going through the annual performance evaluation process. Questionnaires were mailed to employees before and after they had their face-to-face evaluation with their supervisor. Women and men received similar evaluation scores. Men's self-esteem was relatively unaffected by the nature of the feedback, whereas women's self-esteem slightly improved after positive feedback and substantially dropped after negative feedback. After the evaluations, women reported greater intentions to change their behavior based on the evaluation. However, this finding was accounted for by men's higher job status relative to women. The findings for self-esteem were partly explained by women's greater agreement with the feedback compared to men. Future research should explore how the nature of the supervisee-supervisor relationship influences how women and men respond to feedback.
Hybrid Controllers for Path Planning: A Temporal Logic Approach

Robot motion planning algorithms have focused on low-level reachability goals taking into account robot kinematics, or on high level task planning while ignoring low-level dynamics. In this paper, we present an integrated approach to the design of closed–loop hybrid controllers that guarantee by construction that the resulting continuous robot trajectories satisfy sophisticated specifications expressed in the so–called Linear Temporal Logic. In addition, our framework ensures that the temporal logic specification is satisfied even in the presence of an adversary that may instantaneously reposition the robot within the environment a finite number of times. This is achieved by obtaining a Büchi automaton realization of the temporal logic specification, which supervises a finite family of continuous feedback controllers, ensuring consistency between the discrete plan and the continuous execution.
AN EFFICIENT RELIABLE BROADCASTING PROTOCOL FOR AD HOC NETWORKS

Reliable broadcast is an important operation in mobile ad hoc networks (MANETs) (e.g., giving orders, searching routes, and notifying important signals). However, using a naive flooding to achieve reliable broadcasting may be very costly, causing a lot of contention, collision, and congestion, to which we refer as the broadcast stormproblem [1]. This paper proposes an efficient reliable broadcasting protocol by taking care of the potential broadcast storm problem that could occur in the medium-access level. Existing protocols are either unreliable [1, 2, 3, 4, 5, 6], or reliable [7, 8] but based on a too costly approach. Our protocol differs from existing protocols by ensuring reliability but adopting a low-cost unreliable broadcast as a basic operation. Simulation results do justify the efficiency of the proposed protocol.
Generational Status and Academic Achiev Ement among Latino High School Students: Evaluating the Segmented Assimilation Theory

In this study, the author evaluates some of the key assertions of the segmented assimilation theory by examining the generational pattern of achievement among Latino high school students. Segmented assimilation theory posits that the outcomes of immigrants will not necessarily improve monotonically across generations, especially in disadvantaged contexts, and that maintaining familial and ethnic ties can have a protective effect on immigrant students. The author tests these ideas by examining variation in the generational pattern of achievement in low-income schools among Latino high school students. The author finds that changes in achievement across generations generally follow a pattern of classical assimilation with small, though not statistically significant, improvements in achievement from the first to the second generation and from the second to the third generation in both poor and nonpoor schools. Contrary to hypotheses derived from segmented assimilation theory, the author finds no evidence of “downward assimilation” across generations among Latinos attending low-income schools.
Performance and political skill in personal reputation assessments

Purpose – Reputation has many positive outcomes, but little is known about how individuals manage their personal reputation at work. This study aims to investigate the relationships between job performance and political skill on personal reputation.Design/methodology/approach – Ninety‐eight triads from a Midwestern manufacturer provided data. Employees rated their political skill, supervisors rated the employees' job performance, and coworkers rated the employees' personal reputation. The white‐collar respondents were mostly Caucasian, female, middle aged, and moderately tenured in their position. The data were analyzed with regression analysis.Findings – The results illustrated positive political skill‐personal reputation and job performance ‐personal reputation relationships. Job performance was positively associated with personal reputation for politically skilled employees, but not for individuals low in political skill.Research limitations/implications – Job performance was evaluated by employees' su.
Design of a CMOS charge pump for high-performance phase-locked loop

In conventional CMOS charge pump circuits, there are some current mismatching characteristics which result in a phase offset in phase-locked loop circuits. This paper presents a new charge pump circuit after detailed analysis of the current mismatch problem. It combines an error amplifier with reference current sources to achieve good current matching characteristics and lower phase noises, and at the same time it can eliminate charge sharing by using charge removal transistors. The circuit was designed by chartered 0.35 um CMOS technology and simulated by Spectre tools. Simulation results show that the good current matching characteristics can be obtained with the proposed designing scheme.
Opus: University of Bath Online Publication Store Procedural Quests: a Focus for Agent Interaction in Role-playing-games

This version is made available in accordance with publisher policies. Please cite only the published version using the reference above. Abstract. In current videogames non-player characters' (NPCs') abilities to be active, dynamic agents are typically constrained to a bare minimum. Agents have very local behaviours to deal with actions, which can combine in limited ways with global game mechanics to deal with repeated behaviours. Here we present a systems-AI approach to designing NPCs. The proposed NPC design is capable of dynamic dialog, with context generated from both episodic memory and emotional valence towards previous social interactions. The NPCs can be allowed to run independently of users to develop a believable social network of friendships and grudges, with memories supporting such opinions. Additionally, NPCs can spread information in a more realistic manner than the current standard, global mechanisms. This information fomrs a culture, which then serves as the motivation for quests offered to other characters and the user that encounters these societies.
The genesis of mentors’ professional and personal knowledge about teaching: perspectives from the Republic of Ireland

This study investigates the sources of mentors’ knowledge about teaching. A mixed-method research design combining quantitative and qualitative data collection methods was used to examine this area. The findings of the study suggest that: mentors’ knowledge about teaching is practice orientated and emerges from their professional experiences, their teaching skills, their pre-service teacher education and, to a considerable extent, from their own personal experiences. The authors argue that mentors require support to reflect on their early socialisation experiences and their attachment to practice-based experience as a source of professional knowledge, in this way they can better understand and carry out their role as mentors.
