Straddling Teacher Candidates’ Two Worlds to Link Practice and Theory: A Self-Study of Successful and Unsuccessful Efforts

Abstract This self-study examines a teacher educator’s quest to provide an integrated practice-and-theory approach to learning to teach that places the experiences of the teacher candidates at the centre of the curriculum by focussing on their developing questions, challenges and issues through socio-constructivist discussions of their emerging practices. Constraints of university structures with regards to offering such an approach are discussed, including the impact that offering seminars on the university campus rather than in schools has on teacher candidates’ ability to integrate theories and practices of learning to teach. The research questions guiding this study include: How can I understand what process candidates actually undergo during practicum in the development of their ability as teachers vis-à-vis my course? , and How can I re-structure and re-organize my course to enhance the development of candidates’ practice as teachers? Data include interviews with volunteer student participants before and after observations made during classroom visits as well as discussions with groups of students. Analysis is based on reading and rereading the data as well as discussing it with the larger research team. The findings include the realization of how little of my course is integrated into my teacher candidates’ teaching, how much greater the influence of their mentor teacher is, and the extent to which teacher candidates need explicit help and guidance to transform or reframe their teaching. The article concludes with specific suggestions for adjusting a seminar associated with the practicum to enhance the development of a practice-and-theory approach to teaching.
European Conference on Information Systems ( ECIS ) Summer 10-6-2011 UNDERSTANDING AND ADDRESSING USER RESISTANCE TO IS IMPLEMENTATION IN A LEAN CONTEXT

One of the key success factors for the implementation of „Lean‟ concepts is the successful introduction of Information Systems (IS). However, a number of negative outcomes resulting from the implementation of Lean (and its corresponding IS) can lead to strong user resistance to Lean implementation. Using a case study approach supported by interviews with different user groups, this study investigates typical types of user resistance together with strategies for overcoming these resistances. Drawing from prior research on IS and Lean resistance the preliminary findings suggest that Lean IS implementation is not very different from other IS implementations, confirming prior research in this area. However, it also contributes new findings. First, the results showed that information transparency may play an important role in two ways, both as a trigger for user resistance and as a strategy to overcome user resistance. It therefore balances negative and positive effects of user resistance. Second, we found that the order of implementation may have a more significant impact on implementation success than suggested in prior literature.
Parental Reflective Functioning Moderates the Relationship Between Difficult Temperament in Infancy and Behavior Problems in Toddlerhood

Abstract: This study assessed the links between infant negative affect, parental reflective functioning (RF), and toddler behavior problems in a sample of 84 women and their infants. Mothers provided self-report demographic data and completed the Infant Behavior Questionnaire–Revised during a home visit when the infant was 7 months old. They also completed the Child Behavior Checklist over the phone when their infant was 18 months old. During a lab visit when their infant was 16 months old, mothers participated in the Parent Development Interview–Revised Short Form, which was coded for RF. Results suggest that parental RF was not associated with infant negative affect or toddler behavior problems. However, infant negative affect correlated positively with toddler behavior problems and both correlated with cumulative sociodemographic risk. Results of a moderation analysis revealed that RF moderated the relationship between infant negative affect and toddler behavior problems, such that when parental RF was high there was a nonsignificant relationship between infant negative affect and toddler behavior problems.
Lower bounds for the union-find and the split-find problem on pointer machines

A well-known result of Tarjan states that for all n and m n there exists a sequence of n&1 Union and m Find operations that needs at least 0(m .:(m, n)) execution steps on a pointer machine that satisfies the separation condition. Later the bound was extended to 0(n+m .:(m, n)) for all m and n. In this paper we prove that this bound holds on a general pointer machine without the separation condition and we prove that the same bound holds for the Split Find problem as well. ] 1996 Academic Press, Inc.
Effects of oral and intraperitoneal magnesium treatment against cadmium-induced oxidative stress in plasma of rats

Cadmium (Cd) has been recognised as one of the most important environmental and industrial pollutants, and up-to-date investigations have shown that one of the mechanisms of its toxicity is associated with the induction of oxidative stress. The aim of this study was to determine the connection between acute oral and intraperitoneal exposure to Cd and parameters indicative of oxidative stress in the plasma of rats, as well as to examine the potential protective effect of magnesium (Mg) in conditions of acute oral and intraperitoneal Cd poisoning. The experiment was performed on male albino Wistar rats (n=40) randomly divided into control group, Cdor group that received 30 mg kg-1 b.w. Cd by oral gavage, Cd+Mgor group that orally received 50 mg kg-1 b.w. Mg one hour before oral Cd, Cdip group that received 1.5 mg kg-1 b.w. Cd intraperitoneally, and Cd+Mgip group that intraperitoneally received 3 mg kg-1 b.w. Mg 10 min before intraperitoneal Cd. The animals were sacrifi ced 24 h after treatment and the following parameters were measured: superoxidedismutase activity, superoxide anion, total oxidative status, advanced oxidation protein products, and malondialdehyde. All parameters of oxidative stress in rat plasma were negatively affected by Cd treatment with more pronounced negative effects after intraperitoneal treatment, with the exception of superoxide dismutase (SOD) activity. Although both oral and intraperitoneal Mg pretreatment had protective effects, more pronounced benefi cial effects were observed after oral administration, since it managed to completely prevent Cd-induced changes in the investigated parameters. The observed results support the use of Mg as potential protective agent against toxic effects caused by Cd.
Cross racial preferences in viewing sexually explicit material:a comparison bewteen African-American and Caucasian males.

The present study investigated that extent to which the race of actors in an erotic video affected sexual arousal in African-American and Caucasian heterosexual males. It was hypothesized that the two racial groups would be significantly more sexually aroused while watching their respective homoethnic erotic video. The hypothesis was grounded in the modeling effects of Bandura's Social Leaning Theory (1977), the Matching Hypothesis (1982) and worldview differences between African-Americans and Caucasians (Baldwin and Bell, 1985). Thirty-four African-American and Caucasian males were shown homoethnic and non-homoethnic erotic videos while penile circumference, systolic and diastolic blood pressures, and self-report ratings of sexual arousal were measured. In addition, sexual attitude measures and an cultural identity questionnaire were given to the participants to assess whether sexual attitudes and cultural identity were related to sexual responsitivity. The hypothesis was not supported. The results of this study showed that the race of actors in an erotic video did not affect differentially the sexual responding of the AfricanAmerican and Caucasian men. However, systolic blood pressure tended to be a more sensitive indicator of general arousal in African-American men. While this study failed to support the hypothesis, the results did provide data relevant to the study of male sexuality in the laboratory setting. This area of research is still new and deserves more attention.
Identification of RASAL1 as a major tumor suppressor gene in thyroid cancer.

BACKGROUND RAS-coupled MAPK and PI3K pathways play a fundamental role in thyroid tumorigenesis, and classical genetic alterations upregulating these pathways are well characterized. We hypothesized that gene abnormality of negative modulators of these signaling pathways might be an important alternative genetic background for thyroid cancer. METHODS By examining gene expression patterns of negative modulators of RAS signaling, we attempted to identify potential tumor suppressor genes. We then analyzed the methylation and mutation patterns of the identified gene in 101 thyroid tumors and tested its functions in vitro and in vivo to establish the tumor suppressor role in thyroid cancer. RESULTS Among 13 negative modulators of the RAS pathway screened, RASAL1, encoding a RAS GTPase-activating protein, was frequently hypermethylated in thyroid cancers, which was coupled to its silencing in thyroid cancer cells. We also, for the first time, identified the presence of RASAL1 mutations, with a prevalence of 4.88% (n = 2 of 41) in follicular thyroid cancer (FTC) and 16.67% (n = 5 of 30) in anaplastic thyroid cancer (ATC). RASAL1 displayed MAPK- and PI3K-suppressing and thyroid tumor-suppressing activities, which were all impaired by the mutations. Hypermethylation and mutations of RASAL1 were mutually exclusive and collectively found in zero of 20 benign thyroid tumors, 3.22% (n = 1 of 31) of papillary thyroid cancers, 31.70% (n = 13 of 41) of FTCs, and 33.33% (n = 10 of 30) of ATCs. A rate of 20.83% (n = 5 of 24) of tumors carrying RASAL1 mutation or methylation at high levels (>50%) vs 44.16% (n = 34 of 77) of tumors carrying no RASAL1 mutation or methylation at low levels (< 50%) harbored any of the classical mutations (two-sided P = .02, Fisher exact test) in RAS, BRAF, PTEN, and PIK3CA genes in the MAPK and PI3K pathways, revealing a largely mutually exclusive relationship. CONCLUSIONS We identified RASAL1 as a major tumor suppressor gene that is frequently inactivated by hypermethylation and mutations, providing a new alternative genetic background for thyroid cancer, particularly FTC and ATC.
Transformational leadership and corporate entrepreneurship: Cross-level mediation moderation evidence

Purpose The purpose of this paper is to examine how transformational leadership may relate to corporate entrepreneurship by adopting a multilevel approach. The authors also theorized and tested the top-down and bottom-up intermediate process linking transformational leadership and corporate entrepreneurship. Design/methodology/approach Multisource data across different timeframes were collected from 129 managers and 244 employees from 55 units of 27 firms. Findings The results showed that transformational leadership and corporate entrepreneurship were positively related at the unit level. Furthermore, unit-level collective efficacy mediated the relationship between unit-level transformational leadership and unit-level corporate entrepreneurship. The authors also found that the firm-level empowerment climate moderated the indirect effect of unit-level collective efficacy on the relationship between unit transformational leadership and unit-level corporate entrepreneurship. Originality/value First, the goal of this study is to extend the single focus of transformational leadership on corporate entrepreneurship (e.g. Ling et al., 2008) and develop a more thoughtful approach on determining how transformational leaders influence corporate entrepreneurship across levels. This study responds to calls for research to look at the impact of unit-level transformational leaders, such as middle managers, across levels (Ren and Guo, 2011) and creates a multilevel framework in which transformational leaders at the unit level influence the appearance of corporate entrepreneurship at the unit level.
Interaction between infants: understanding intersubjectivity and emotional expression

Infants are born able to express their emotions, and they can synchronise their expressions with their mothers' acts. They are coherent psychological beings, well equipped for social life and sensitive to supportive expressions of adults. Psychologists differ in their interpretation of the infant's independent initiative in these interactions. Although the theoretical importance of research on infant-to-infant emotional expression and communication is obvious, there are few studies investigating how infants under 10 months communicate with peers and the emotions that are expressed. In an attempt to answer questions about young infants' emotional development and communicative emotional expression, I have studied the interaction of pairs of infants between 20 and 42 weeks of age. I also investigated the sensitiveness of paired infants to the motives and feelings of their partners. I measured turn-taking, imitation, and both local and general bodily emotional expressions of a reciprocal or complementary form. A Cross-Sectional study recorded pairs of infants at 20-25 weeks (6 months), 31-35 weeks (8 months), 36-40 weeks (9 months). Nine subjects from middle class families, 3 girls and 6 boys were videotaped in same age dyads, seated on their push-chairs, facing each other. There were 3 dyads at each age, 2 girl+boy, 1 boy+boy. In addition, 2 boys and 2 girls were recorded at 6, 8 and 9 months), to obtain Longitudinal data. At each age there was a pair of boys, a pair of girls, and 4 girl+boy pairs. Finally, in a study of interactions with a self-image, 9 subjects (4 at 6 months, 3 at 8 months, and 2 at 9 months) were videotaped facing their reflection in a mirror box containing a concealed video camera. Micro-analysis of the first 2 minutes of interaction produced a detailed description of the infant's behaviours. Four levels of coding were created by grouping microanalytic categories: to define, first, Behavioural activities; then a Functional level; and finally, Negotiatory and Emotional acts. Results show that 6 month-olds try to make contact, but they do not sustain interaction. As a result, invitations for interactions occur frequently, but they are not always followed by appropriate responses. The infants are very interested and very friendly to one another, but as a result of
Complete Geometric Query Languages

We extend Chandra and Harel's seminal work on computable queries for relational databases to a setting in which also spatial data may be present, using a constraint-based data model. Concretely, we introduce both coordinate-based and point-based query languages that are complete in the sense that they can express precisely all computable queries that are generic with respect to certain classes of transformations of space, corresponding to certain geometric interpretations of spatial data. The languages we introduce are obtained by augmenting basic languages with a “while” construct. We also show that the respective basic point-based languages are complete, relative to the subclass of the corresponding generic queries consisting of those that are expressible in the relational calculus with real polynomial constraints.
A Monetary Theory with Non-Degenerate Distributions

Dispersion of money balances among individuals is the basis for a range of policies but it has been abstracted from in monetary theory for tractability reasons. In this paper, we fill in this gap by constructing a tractable search model of money with a non-degenerate distribution of money holdings. We assume search to be directed in the sense that buyers know the terms of trade before visiting particular sellers. Directed search makes the monetary steady state block recursive in the sense that individuals' policy functions, value functions and the market tightness function are all independent of the distribution of individuals over money balances, although the distribution affects the aggregate activity by itself. Block recursivity enables us to characterize the equilibrium analytically. By adapting lattice-theoretic techniques, we characterize individuals' policy and value functions, and show that these functions satisfy the standard conditions of optimization. We prove that a unique monetary steady state exists. Moreover, we provide conditions under which the steady-state distribution of buyers over money balances is non-degenerate and analyze the properties of this distribution.
BioJazz: in silico evolution of cellular networks with unbounded complexity using rule-based modeling

Systems biologists aim to decipher the structure and dynamics of signaling and regulatory networks underpinning cellular responses; synthetic biologists can use this insight to alter existing networks or engineer de novo ones. Both tasks will benefit from an understanding of which structural and dynamic features of networks can emerge from evolutionary processes, through which intermediary steps these arise, and whether they embody general design principles. As natural evolution at the level of network dynamics is difficult to study, in silico evolution of network models can provide important insights. However, current tools used for in silico evolution of network dynamics are limited to ad hoc computer simulations and models. Here we introduce BioJazz, an extendable, user-friendly tool for simulating the evolution of dynamic biochemical networks. Unlike previous tools for in silico evolution, BioJazz allows for the evolution of cellular networks with unbounded complexity by combining rule-based modeling with an encoding of networks that is akin to a genome. We show that BioJazz can be used to implement biologically realistic selective pressures and allows exploration of the space of network architectures and dynamics that implement prescribed physiological functions. BioJazz is provided as an open-source tool to facilitate its further development and use.

Falls in people with MS—an individual data meta-analysis from studies from Australia, Sweden, United Kingdom and the United States

Background: Falls are common in people with multiple sclerosis (PwMS). Previous studies have generally included small samples and had varied methods. Objectives: The objectives of this paper are to compile fall rates across a broad range of ages and disease severity and to definitively assess the extent to which MS-associated and demographic factors influence fall rates. Methods: Individual data from studies in four countries that prospectively measured falls for three months were analyzed. We determined fall rates, prevalence of fallers (≥1 falls) and frequent fallers (≥2 falls), location and timing of falls, and fall-related demographic factors. Results: A total of 537 participants reported 1721 falls: 56% were fallers and 37% frequent fallers. Most falls occurred indoors (65%) between 6 a.m. and 6 p.m. (75%). Primary progressive MS was associated with significantly increased odds of being a faller (odds ratio (OR) 2.02; CI 1.08–3.78). Fall risk peaked at EDSS levels of 4.0 and 6.0 with significant ORs between 5.30 (2.23–12.64) and 5.10 (2.08–12.47). The fall rate was lower in women than men (relative risk (RR) 0.80; CI 0.67–0.94) and decreased with increasing age (RR 0.97 for each year, CI 0.95–0.98). Conclusion: PwMS are at high risk of falls and there are important associations between falls and MS-associated disability, gender and age.
Androgen receptor polymorphisms: Association with prostate cancer risk, relapse and overall survival

Several reports have suggested that one or both of the trinucleotide repeat polymorphisms in the human androgen receptor (hAR) gene, (CAG)n coding for polyglutamine and (GGC)ncoding for polyglycine, may be associated with prostate cancer risk; but no study has investigated their association with disease progression. We present here a study of both hAR trinucleotide repeat polymorphisms not only as they relate to the initial diagnosis but also as they are associated with disease progression after therapy. Lymphocyte DNA samples from 178 British Caucasian prostate cancer patients and 195 control individuals were genotyped by PCR for the (CAG)n and (GGC)n polymorphisms in hAR. Univariate Cox proportional hazard analysis indicated that stage, grade and GGC repeat length were individually significant factors associated with disease‐free survival (DFS) and overall survival (OS). The relative risk (RR) of relapse for men with more than 16 GGC repeats was 1.74 (95% CI 1.08–2.79) and of dying from any cause, 1.98 (1.13–3.45). Adjusting for stage and grade, GGC effects remained but were not significant (RRDFS= 1.60, p = 0.052; RROS= 1.65, p = 0.088). The greatest effects were in stage T1‐T2 (RRDFS= 3.56, 95% CI 1.13–11.21) and grade 1 (RRDFS= 6.47, 95% CI 0.57–72.8) tumours. No differences between patient and control allele distributions were found by odds‐ratio analysis, nor were trends with stage or grade evident in the proportion of short CAG alleles. Non‐significant trends with stage and grade were found in the proportion of short GGC alleles. The (GGC)n polymorphism in this population is a significant predictor of disease outcome. Since the (GGC)n effect is strongest in early‐stage tumours, this marker may help forecast aggressive behaviour and could be used to identify those patients meriting more radical treatment. Int. J.

Assessment of Ethical Ideals and Ethical Manners in Care of Older People

The aim of this study is to establish structured clusters and well-defined ontological entities (nodes) describing ethical values as both ideal and opportunity for ethical manner as perceived by thecaregiver.In this study, we use Bayesian Belief Networks (BBNs) to analyse ethical values (ethos) and ethical manners in daily work with older people. Material is based on questionnaire data collected by the instrument for the self-assessment of individual ethos in the care of older people(ISAEC) in spring 2007 in a municipality in Western Finland. This study is unique in its kind, both concerning the selected approach and methodological questions. BBNs have not been used significantly in nursing research, nor are there any studies that examine the ethical possibilities with focus on the probable effects upon changing conditions.
