The Different Tax Treatment of Investment Advisory Fees and Brokerage Fees; The Lower the Fiduciary Duty the Better the Tax Consequences

The current tax laws favor brokerage fees as compared to investment advisory fees, even though investment advisors are held to a higher standard of fiduciary duty. My article examines the different tax treatment of investment advisory fees and brokerage fees, analyzes the policy considerations of such treatment and proposes alternatives to the current system. Considering the large number of American investing in the securities markets, it is important that our tax laws be written in a way that encourages taxpayers to seek investment professionals who are held to higher standards of conduct. The policy implications of brokerage fees receiving preferable tax treatment are considerable, yet have been ignored by Congress. This article will hopefully open a debate on the tax treatment of fees that investment professionals charge

Development of a Multidimensional, Multi-Informent Measure of Teacher Mindfulness as Experienced and Expressed in the Middle School Classroom

In response to growing interest in mindfulness as a support for educators, the current study sought to create and test a new multidimensional and multi-informant measure of teacher mindfulness in the classroom. To counter some of the limitations of context-general self-reports, we designed two theoretically based classroom-specific measures that capture the experience and expression of mindful teacher behavior from the perspective of teachers and students. Drawing on emerging consensus from experts on mindfulness in education, the measures incorporated three dimensions of mindfulness, namely, Calm, Clear, and Kind teacher behavior in the classroom, as well as their antitheses, namely, Reactive, Distracted, and Critical teacher behavior. Utilizing data from 78 sixth- to eighth-grade teachers and 550 of their students, teacher- and student-report item sets tapping these dimensions were tested for reliability and validity across three time points. Based on confirmatory factor, reliability, structural invariance, and correlational analyses, subscales generally demonstrated satisfactory psychometric properties, cross-year stabilities, convergent and criterion validity with multiple established measures, and some overlap across reporters. In terms of connections to observer ratings from the CLASS-S, teacher subscales showed consistent but modest connections, whereas student subscales showed higher correlations (especially at time 2), suggesting that students and observers converged in their perceptions of teachers’ expressions of mindfulness. Possible improvements to both measures as well as implications for future research on teacher mindfulness are discussed

Fuzzy cellular model for on-line traffic simulation

This paper introduces a fuzzy cellular model of road traffic that was intended for on-line applications in traffic control. The presented model uses fuzzy sets theory to deal with uncertainty of both input data and simulation results. Vehicles are modelled individually, thus various classes of them can be taken into consideration. In the proposed approach, all parameters of vehicles are described by means of fuzzy numbers. The model was implemented in a simulation of vehicles queue discharge process. Changes of the queue length were analysed in this experiment and compared to the results of NaSch cellular automata model.Comment: The original publication is available at http://www.springerlink.co

A realistic two-lane traffic model for highway traffic

A two-lane extension of a recently proposed cellular automaton model for traffic flow is discussed. The analysis focuses on the reproduction of the lane usage inversion and the density dependence of the number of lane changes. It is shown that the single-lane dynamics can be extended to the two-lane case without changing the basic properties of the model which are known to be in good agreement with empirical single-vehicle data. Therefore it is possible to reproduce various empirically observed two-lane phenomena, like the synchronization of the lanes, without fine-tuning of the model parameters

Human behavior as origin of traffic phases

It is shown that the desire for smooth and comfortable driving is directly responsible for the occurrence of complex spatio-temporal structures (``synchronized traffic'') in highway traffic. This desire goes beyond the avoidance of accidents which so far has been the main focus of microscopic modeling and which is mainly responsible for the other two phases observed empirically, free flow and wide moving jams. These features have been incorporated into a microscopic model based on stochastic cellular automata and the results of computer simulations are compared with empirical data. The simple structure of the model allows for very fast implementations of realistic networks. The level of agreement with the empirical findings opens new perspectives for reliable traffic forecasts.Comment: 4 pages, 4 figures, colour figures with reduced resolutio

Coherent Moving States in Highway Traffic (Originally: Moving Like a Solid Block)

Recent advances in multiagent simulations have made possible the study of realistic traffic patterns and allow to test theories based on driver behaviour. Such simulations also display various empirical features of traffic flows, and are used to design traffic controls that maximise the throughput of vehicles in heavily transited highways. In addition to its intrinsic economic value, vehicular traffic is of interest because it may throw light on some social phenomena where diverse individuals competitively try to maximise their own utilities under certain constraints. In this paper, we present simulation results that point to the existence of cooperative, coherent states arising from competitive interactions that lead to a new phenomenon in heterogeneous highway traffic. As the density of vehicles increases, their interactions cause a transition into a highly correlated state in which all vehicles practically move with the same speed, analogous to the motion of a solid block. This state is associated with a reduced lane changing rate and a safe, high and stable flow. It disappears as the vehicle density exceeds a critical value. The effect is observed in recent evaluations of Dutch traffic data.Comment: Submitted on April 21, 1998.

Generalized Force Model of Traffic Dynamics

Floating car data of car-following behavior in cities were compared to existing microsimulation models, after their parameters had been calibrated to the experimental data. With these parameter values, additional simulations have been carried out, e.g. of a moving car which approaches a stopped car. It turned out that, in order to manage such kinds of situations without producing accidents, improved traffic models are needed. Good results have been obtained with the proposed generalized force model.Comment: For related work see http://www.theo2.physik.uni-stuttgart.de/helbing.htm
