Opening windows into the mind: mothers' preferences for mental state explanations and children's theory of mind

A new questionnaire, the Maternal Mental State Input Inventory (MMSII) was created to measure mothers' preferences for introducing and elaborating on mental states in conversation with their young children. In two studies, the questionnaire was given to mothers of young children, and the children's theory of mind (ToM) development was assessed with standard tasks. In both studies, the questionnaire exhibited good internal reliability, and significant correlations emerged between mothers' self-reported preferences for elaborated, explanatory talk about the mental states and children's theory of mind performance. Further, mothers' conversational preferences, as measured by the MMSII, were the best predictors of children's theory of mind development when relevant control variables were included in the analyses. These results converge with naturalistic observational research that has demonstrated links between mothers' conversational styles and their children's theory of mind. They go further in suggesting that mothers' tendencies toward elaborated, explanatory talk about a range of mental states is particularly beneficial to children's theory of mind development.

Design and implementation of a windows-based parallel computing environment for large scale optimization

A parallel computing environment to support optimization of large-scale engineering systems is designed and implemented on Windows-based personal computer networks, using the master-worker model and the Parallel Virtual Machine (PVM). It is involved in decomposition of a large engineering system into a number of smaller subsystems optimized in parallel on worker nodes and coordination of subsystem optimization results on the master node. The environment consists of six functional modules, i.e. the master control, the optimization model generator, the optimizer, the data manager, the monitor, and the post processor. Object-oriented design of these modules is presented. The environment supports steps from the generation of optimization models to the solution and the visualization on networks of computers. User-friendly graphical interfaces make it easy to define the problem, and monitor and steer the optimization process. It has been verified by an example of a large space truss optimization.

Regulation of bone biology by prostaglandin endoperoxide H synthases (PGHS): A rose by any other name...

It is well established that prostaglandins are essential mediators of bone resorption and formation. In the early 1990s, it was discovered that enzymatic reactions producing prostaglandins were regulated by two cyclooxygenase enzymes, one producing prostaglandins constitutively in tissues like the stomach, prostaglandin endoperoxide H synthase-1 (PGHS-1 or COX-1), and another induced by mitogens or inflammatory mediators (PGHS-2 or COX-2). This neat distinction has not been maintained because both enzymes act in different cell systems to provide physiological signaling, constitutively or by induction under certain conditions. For example, the regulation patterns of PGHS-1 and PGHS-2 are distinct, but the evidence shows that PGHS-2 functions constitutively in the skeleton. PGHS-2 hits quickly been established, therefore, as a key regulator of bone biology, capable of rapid and transient expression in bone cells, and mediating osteoclastogenesis, mechanotransduction, bone formation and fracture repair. The goal of this review is to Summarize the current state of our knowledge of PGHS regulation of bone metabolism and to identify some of the key unresolved challenges and questions that require further study.

A windows program for the derivation of steady-state equations in enzyme systems

Despite the number of computer-assisted methods described for the derivation of steady-state equations of enzyme systems, most of them are focused on strict steady-state conditions or are not able to solve complex reaction mechanisms. Moreover, many of them are based on computer programs that are either not readily available or have limitations. We present here a computer program called WinStes, which derives equations for both strict steady-state systems and those with the assumption of rapid equilibrium, for branched or unbranched mechanisms, containing both reversible and irreversible conversion steps. It solves reaction mechanisms involving up to 255 enzyme species, connected by up to 255 conversion steps. The program provides all the advantages of the Windows programs, such as a user-friendly graphical interface, and has a short computation time. WinStes is available free of charge on request from the authors. (c) 2006 Elsevier Inc. All rights reserved.
