Toward Improving the Modeling of MTMM Data: A Response to Geiser, Koch, and Eid (2014)

Geiser, Koch, and Eid (2014) expressed their views on an article we published describing findings from a simulation study and an empirical study of multitrait–multimethod (MTMM) data. Geiser and colleagues raised concerns with (a) our use of the term bias, (b) our statement that the correlated trait–correlated method minus one [CT–C(M–1)] model is not in line with Campbell and Fiske’s (1959) conceptualization of MTMM data, (c) our selection of a data-generating model for our simulation study, and (d) our preference for the correlated trait–correlated method (CT–CM) model over the CT–C(M–1) model. Here, we respond to and elaborate on issues raised by Geiser et al. We maintain our position on each of these issues and point to the interpretational challenges of the CT–C(M–1) model. But, we clarify our opinion that none of the existing structural models for MTMM data are flawless; each has its strengths and each has its weaknesses. We further remind readers of the goal, findings, and implications of our recently published article.
Individual factors associated with buying addiction: An empirical study

This study analyses the relationship between buying addiction and a set of individual factors. The results show that addictive buying is significantly associated with the personal variables considered in our research; what is more, the discriminant analysis carried out suggests a “hierarchy” of defining factors common to those individuals who present a high level of addictive buying: anxiety, depression, and obsessive-compulsiveness are the variables which are most closely linked to this psychological addiction, followed by passive coping, low self-esteem, low conscientiousness, external locus of control, and sensation seeking, respectively. The implications and potential limitations of these findings, as well as some recommendations for future research, are presented.
In Vitro and In Vivo Characterization of a Murine Cytomegalovirus with a Transposon Insertional Mutation at Open Reading Frame M43

ABSTRACT We have recently generated a pool of murine cytomegalovirus (MCMV) mutants by using a Tn3-based transposon mutagenesis approach. In this study, one of the MCMV mutants, RvM43, which contained the transposon inserted in open reading frame M43, was characterized. Our results provide the first direct evidence to suggest that M43 is not essential for viral replication in vitro in NIH 3T3 cells. Moreover, RvM43 exhibited a titer similar to that of the wild-type virus in the lungs, livers, spleens, and kidneys of both BALB/c and SCID mice and was as virulent as the wild-type virus in killing SCID mice that had been intraperitoneally infected with the viruses. In contrast, titers of the mutant virus in the salivary glands of the infected animals at 21 days postinfection were significantly (100 to 1,000-fold) lower than those of the wild-type virus and a rescued virus that restored the M43 region and its expression. Thus, M43 appears to be not essential for viral growth in vivo in the lungs, livers, spleens, and kidneys of infected animals and is also dispensable for virulence in killing SCID mice. Moreover, our results suggest that M43 is an MCMV determinant for growth in the salivary glands. Studies of viral genes required for replication in the salivary glands are important in understanding the mechanism of viral tropism for the salivary glands and shedding in saliva, which is believed to be one of the major routes of CMV transmission among healthy human populations.
What mothers do: everyday routines and rituals and their impact upon young children’s use of drawing for meaning making

This paper draws upon evidence from a three‐year longitudinal study of young children drawing across home, pre‐school and school. The study shows how the belief systems of significant adults and more able peers/siblings impact upon the child’s access to, use of and beliefs about drawing. Concentrating upon the children when in the Foundation Stage (aged between three and five), the paper highlights: • the importance of the mother’s role in organizing the home space, the child’s time and his or her access to materials; • gendered responses to an environment in which the mother is a constant presence in comparison with the limited presence of the father.
HIGHER DISEASE PREVALENCE CAN INDUCE GREATER SOCIALITY: A GAME THEORETIC COEVOLUTIONARY MODEL

Abstract There is growing evidence that communicable diseases constitute a strong selective force on the evolution of social systems. It has been suggested that infectious diseases may determine upper limits of host sociality by, for example, inducing territoriality or early juvenile dispersal. Here we use game theory to model the evolution of host sociality in the context of communicable diseases. Our model is then augmented with the evolution of virulence to determine coevolutionarily stable strategies of host sociality and pathogen virulence. In contrast to a controversial hypothesis by Ewald (1994), our analysis indicates that pathogens may become more virulent when contact rates are low, and their prevalence can ultimately induce greater sociality.
The incidence of superfecundation and of double paternity in the general population.

It is estimated that at least one dizygotic (DZ) twin maternity in twelve is preceded by superfecundation (the fertilization of two ova by sperm from different coitions). Presumably this parameter varies from population to population eg. with coital rates and rates of double ovulation. Sometimes superfecundation occurs by two different men. The frequency with which this occurs must depend on rates of infidelity (promiscuity). It is suggested that among DZ twins born to married white women in the U.S., about one pair in 400 is bipaternal. The incidence may be substantially higher in small selected groups of dizygotic twin maternities, eg. those of women engaged in prostitution.
Correlation of naturally occurring infrasonics and selected human behavior.

An initial attempt is made to determine whether infrasonic waves generated by storms of distant origin affect local human behavior. Severe storm activity in North America was compared with the automobile accident rate and the rate for absenteeism among school children in the area of Chicago Illinois during the first 28 days of May 1967. The results suggest that a correlation may exist between the presence of infrasonic disturbances in the Chicago area and changes in selected human behavior. It is urged that more comprehensive studies of this nature be carried out.
SCHOOL ENVIRONMENT AND SIXTH FORM PUPILS‘ APPROACHES TO LEARNING

Summary. The paper presents results from a study of Australian pupils in their final year of secondary schooling. The investigation is based on a model of the relation between pupils' perceptions, approaches to learning and learning outcomes derived from the work of Biggs in Australia and Entwistle and Ramsden in Britain. Between-school differences in perceptions of sixth form environments and their pupils' approaches to learning in three school sectors and 50 schools are identified. A key finding is that perceived school environments and pupils' learning are related in a systematic way. School environments offering supportive teaching, coherent structure, emphasis on autonomy and moderate stress on achievement are associated with learning involving an active search for understanding, organised study methods and avoidance of superficial approaches. Schools characterised by extreme emphasis on formal academic achievement, in which teaching is narrowly focused on examination success, are associated with a tendency towards minimalist, reproductive and uncompromisingly competitive approaches to learning. Interview results are presented that offer support for a causal interpretation of these relations. Examination performance is found to be negatively correlated with surface approach and positively, but very weakly, correlated with deep approach. Some implications of the findings for school effectiveness research are outlined.
Tactical globalization: learning from the Singapore experiment

As so often happens during times of economic turmoil, the public discourse around issues of education has swung towards concerns of whether schools are properly preparing students for a future of uncertain prospects of employment and prosperity. From one capital to the next, politicians warn of the perilous economic waters awaiting students just outside the classroom doors, and argue that the only possible means of surviving the storm is to create an educational system that is focused on the needs of the global market and the task of turning students into workers who can be ‘competitive’ in such a market. Such rhetoric makes explicit the long-standing connection often made between education and economic well-being. The difference recently in such pronouncements, however, is the almost reflexive invoking of globalisation as an inexorable and anxiety-provoking economic force that should shape educational policies and pedagogy. It is important to consider how policymakers and the state use education in such moments, both as a rhetorical trope as well as an instrument of state ideology. Anyone involved in education should be attentive to what is implied in the discourse employed by the state, and how that will ultimately shape what happens in individual schools. One way to gain insights into the confluence of global economic and cultural flows and national education policy is to study a setting in which such concerns are ongoing. Aaron Koh, in Tactical Globalization: Learning from the Singapore Experiment, offers just such a study of the way the state attempts to use education policy as a tool of economic power as well as nation-building. His astute and insightful exploration of the ways in which the government of Singapore attempts to balance anxieties of global economic competitiveness with issues of national identity offers useful lessons for understanding how the tensions created by the pull of the global and push of the local are played out in discussions of education. In doing so he reminds us of how education functions as a tool of ideology and how that is reflected in the public discourse about schools and students. Koh’s book not only offers a detailed and important discussion of the nexus of politics, economics, and education in Singapore, but provides a model and theoretical perspective through which we can conduct similar work in other settings. Singapore provides a fascinating site for such research. An island city-state just off the Malay Peninsula with a population of about five million, Singapore has thrived economically as it has embraced the opportunities provided by transnational flows of capital. As an island nation with no natural resources or significant industrial base, however, its economic successes are dependent on the human capital of its population.

How Does Foreign Direct Investment Really Affect Developing Countries' Growth?

This paper contributes to the literature on foreign direct investment (FDI) and economic growth in two main ways. First, we examine the effect of FDI on economic growth for 44 developing countries over the period 1970 to 2005 using heterogeneous panel cointegration techniques that are robust to omitted variables and endogenous regressors. In contrast to previous studies, we find that FDI has, on average, a negative effect on growth in developing countries, but that there are large cross-country differences in the growth effects of FDI. Second, we use a general-tospecific model selection approach to systematically search for country-specific factors explaining the cross-country differences in the growth effects of FDI. Contrary to previous results, we find that the cross-country differences in per capita income, human capital, openness, and financial market development cannot explain the cross-country differences in the growth effects of FDI. Instead, the growth effects of FDI are positively related to freedom from government intervention and freedom from business regulation, and negatively related to FDI volatility and natural resource dependence.
Gang scheduling with memory considerations

A major problem with time slicing on parallel machines is memory pressure, as the resulting paging activity damages the synchronism among a job's processes. An alternative is to impose admission controls, and only admit jobs that fit into the available memory. Despite suffering from delayed execution, this leads to better overall performance by preventing the harmful effects of paging and thrashing.
The Unseen World: Race, Class, and Gender Analysis in Science Education Research

Over the past several years there has been a concerted effort among many math and science educators to improve math and science education for minority students. Much of this effort has been aimed at developing new delivery mechanisms (i.e., Saturday or after-school programs and science academies) or enhancing the current school curriculum. In short, most of the current intervention in math and science education is active and takes place in a manner that leads to direct instructional improvement for students. However, such efforts only capture part of the math and science educational enterprise. While the growing attention given to cognitive research in education is reflective of the importance of research on the lives of school children, basic educational research in math and science education has not received the full attention of those concerned with the improvement of math and science education. Cognitive research has become increasingly more important to education. As Resnick (1984) indicated in a National Academy of Education report on research and education, the new challenges for education cannot "be met with the methods of the past"; rather, they demand new and continued efforts to know and understand, through research, the process of teaching and learning:

The Face Semigroup Algebra of a Hyperplane Arrangement

Abstract This article presents a study of an algebra spanned by the faces of a hyperplane arrangement. The quiver with relations of the algebra is computed and the algebra is shown to be a Koszul algebra. It is shown that the algebra depends only on the intersection lattice of the hyperplane arrangement. A complete system of primitive orthogonal idempotents for the algebra is constructed and other algebraic structure is determined including: a description of the projective indecomposable modules, the Cartan invariants, projective resolutions of the simple modules, the Hochschild homology and cohomology, and the Koszul dual algebra. A new cohomology construction on posets is introduced, and it is shown that the face semigroup algebra is isomorphic to the cohomology algebra when this construction is applied to the intersection lattice of the hyperplane arrangement.
P‐ and S‐velocity anomalies in the upper mantle beneath Europe from tomographic inversion of ISC data

We present a new tomographic model for P- and S-velocity anomalies beneath Europe (30°N-55°N, 5°W-40°E), extending in depth up to 700 km and constrained by inversion of data from the International Seismological Center (ISC) catalogue. The algorithm uses the traveltimes from events located in the study area recorded by all available worldwide stations, as well as times from teleseismic events recorded by European stations. The events from the ISC catalogue have been relocated and combined into composite events. All the traveltimes were corrected for crustal structure using the reference model EuCRUST-07. The resulting velocity anomalies show similar large-scale patterns as observed in previous studies, but have a higher resolution, which allows detection of some features in more detail. For example, it is now possible to assess the depth extension of the small slow velocity body beneath the Eifel region and Eger graben. The P and the S model show a good consistency in the uppermost 200 km below most of the European area and in some parts even in the deeper layers (e.g. beneath the Apennines and the Hellenic arc). The new model provides clear images of some principal features, which were previously detected in a limited number of studies, while the comparison between P- and S-velocity anomalies provides novel constraints to address on their nature (e.g. the gap in the Adriatic plate subducted below the central-southern Apennines). In this paper, we pay special attention to testing the reliability of the results. The random noise effect is evaluated using a test with independent inversion of two data subsets (with odd/even events). The spatial resolution is estimated using different checkerboard tests. Furthermore, we present a synthetic model with realistic patterns, which reproduces after performing forward and inverse modelling the same shape and amplitudes of the anomalies as in the case of the real data inversion. In this case, the parameters of the model can be used to assess the amplitudes of P and S anomalies that is critical for evaluation of other petrophysical parameters (temperature, density, composition, etc.) in the upper mantle. © 2009 The Authors Journal compilation © 2009 RAS.
The topoisomerase II inhibitor VM-26 induces marked changes in histone H1 kinase activity, histones H1 and H3 phosphorylation, and chromosome condensation in G2 phase and mitotic BHK cells

We have examined the effects of topoisomerase inhibitors on the phosphorylation of histones in chromatin during the G2 and the M phases of the cell cycle. Throughout the G2 phase of BHK cells, addition of the topoisomerase II inhibitor VM-26 prevented histone H1 phosphorylation, accompanied by the inhibition of intracellular histone H1 kinase activity. However, VM-26 had no inhibitory effect on the activity of the kinase in vitro, suggesting an indirect influence on histone H1 kinase activity. Entry into mitosis was also prevented, as monitored by the absence of nuclear lamina depolymerization, chromosome condensation, and histone H3 phosphorylation. In contrast, the topoisomerase I inhibitor, camptothecin, inhibited histone H1 phosphorylation and entry into mitosis only when applied at early G2. In cells that were arrested in mitosis, VM-26 induced dephosphorylation of histones H1 and H3, DNA breaks, and partial chromosome decondensation. These changes in chromatin parameters probably reverse the process of chromosome condensation, unfolding condensed regions to permit the repair of strand breaks in the DNA that were induced by VM- 26. The involvement of growth-associated histone H1 kinase in these processes raises the possibility that the cell detects breaks in the DNA through their effects on the state of DNA supercoiling in constrained domains or loops. It would appear that histone H1 kinase and topoisomerase II work coordinately in both chromosome condensation and decondensation, and that this process participates in the VM-26- induced G2 arrest of the cell.
A Family of Origin Workshop: Process and Evaluation

This study examined the effectiveness of family of origin therapy as experienced in a workshop format. The Family of Origin Workshop is a 6-hour session that strives for the goal of increasing personal authority. A description of the workshop is included. Statistically significant results between pretest and posttest scores were obtained for the Intergenerational Individuation and Spousal Individuation scales. Participants reported increased ability to individuate. A schema for the achievement of personal authority is proposed as one possible explanation for the relational pattern that occurs in this maturation process. Participants attribute changes resulting from the Family of Origin Workshop to content-oriented variables.
Compartmental Architecture and Dynamics of Hematopoiesis

Background Blood cell formation is maintained by the replication of hematopoietic stem cells (HSC) that continuously feed downstream “compartments” where amplification and differentiation of cells occurs, giving rise to all blood lineages. Whereas HSC replicate slowly, committed cells replicate faster as they become more differentiated. Methodology/Significant Finding We propose a multi-compartment model of hematopoiesis, designed on the principle of cell flow conservation under stationary conditions. Cells lost from one compartment due to differentiation are replaced by cells from the upstream compartment. We assume that there is a constant relationship between cell input and output in each compartment and fix the single parameter of the model using data available for granulocyte maturation. We predict that ∼31 mitotic events separate the HSC from the mature cells observed in the circulation. Besides estimating the number of compartments, our model allows us to estimate the size of each compartment, the rate of cell replication within each compartment, the mean time a given cell type contributes to hematopoiesis, the amplification rate in each compartment, as well as the mean time separating stem-cell replication and mature blood-cell formation. Conclusions Despite its simplicity, the model agrees with the limited in vivo data available and can make testable predictions. In particular, our prediction of the average lifetime of a PIG-A mutated clone agrees closely with the experimental results available for the PIG-A gene mutation in healthy adults. The present elucidation of the compartment structure and dynamics of hematopoiesis may prove insightful in further understanding a variety of hematopoietic disorders.
A suboptimal model predictive formation control

We investigate the leader-following formation control of mobile robots through the model predictive control (MPC) in this paper. We establish its control stability by adding a terminal state penalty to the cost function and a terminal state region to the optimisation constraints. We also design a terminal state region based on an input-output feedback linearisation controller for the MPC. A suboptimal stable solution is sought to reduce the computational time used in the MPC. Simulations on the control are provided to verify the proposed control strategy.
Reflective Thinking among Preservice Elementary Mathematics Teachers.

Four preservice elementary teachers were studied during a field-based mathematics methods course. The purpose of the study was to investigate the elements of mathematics teaching and learning the preservice teachers found problematic and how they resolved those problems. Data were collected in the form of individual interviews, group discussions, and individual journals. The preservice teachers exhibited concerns about the classroom context, pedagogy of mathematics, children's mathematical thinking, and, to a lesser extent, the mathematics content. The data indicate a relationship between the preservice teachers' locus of authority and the reflective quality of their thinking.
