Factors that influence reinforcer choice have been examined in a number of applied studies (e.g., Neef, Mace, Shea, & Shade, 1992; Shore, Iwata, DeLeon, Kahng, & Smith, 1997; Tustin, 1994). However, no applied studies have evaluated the effects of postsession reinforcement on choice between concurrently available reinforcers, even though basic…

Current research provides few suggestions for modifications to functional analysis procedures to accommodate low rate, high intensity problem behavior. This study examined the results of the extended duration functional analysis procedures of Kahng, Abt, and Schonbachler (2001) with six children admitted to an inpatient hospital for the treatment of severe problem behavior. Results of initial functional analyses (Iwata, Dorsey, Slifer, Bauman, & Richman, 1982/1994) were inconclusive for all children because of low levels of responding. The altered functional analyses, which changed multiple variables including the duration of the functional analysis (i.e., 6 or 7 hrs), yielded clear behavioral functions for all six participants. These results add additional support for the utility of an altered analysis of low rate, high intensity problem behavior when standard functional analyses do not yield differentiated results.

Changbum Cho, Jae-Young Byon, Keumah Kahng, Young-San Park, and Hyun-Sook Jung National Institute of Meteorological Research, Korea Meteorological Administration, Korea National Institute of Meteorological Research established micro-meteorology monitoring system at the Nakdong River of South Korea since 2010 in order to study the micro-meteorological impact due to nationwide major river development project. A total of 37 automatic weather stations are in operation at areas near the dams which were constructed as part of this project. The weather stations mainly measure air temperature, humidity, and wind, with some of the stations measuring radiation and heat fluxes. More than half of the stations are installed on agricultural areas and the rest are installed in an industrial area. The data collected from the stations are used to observe the micrometeorological system and used as an input to numerical models, which compose a meteorological environment impact assessment tool.

We present the effect of mergers, a term which we use to mean a temporary alliance, in the dynamics of the three-agent model studied by Ben-Naim, Kahng and Kim and by Rador and Mungan. Mergers are possible in three-agent games because two agents can combine forces against the third player and thus increase their probability to win a competition. We implement mergers in this three-agent model via resolving merger and no-merger units of competition in terms of a two-agent unit. This way one needs only a single parameter which we have called the competitiveness parameter. We have presented an analytical solution in the fully competitive limit. In this limit the score distribution of agents is stratified and self-similar.

Factors that influence reinforcer choice have been examined in a number of applied studies (e.g., Neef, Mace, Shea, & Shade, 1992; Shore, Iwata, DeLeon, Kahng, & Smith, 1997; Tustin, 1994). However, no applied studies have evaluated the effects of postsession reinforcement on choice between concurrently available reinforcers, even though basic findings indicate that this is an important factor to consider (Hursh, 1978; Zeiler, 1999). In this bridge investigation, we evaluated the influence of postsession reinforcement on choice of two food items when task responding was reinforced on progressive-ratio schedules. Participants were 3 children who had been diagnosed with developmental disabilities. Results indicated that response allocation shifted from one food item to the other food item under thinner schedules of reinforcement when no postsession reinforcement was provided. These findings suggest that the efficacy of instructional programs or treatments for problem behavior may be improved by restricting reinforcers outside treatment sessions.

Researchers have shown that both differential reinforcement and response cost within token economies are similarly effective for changing the behavior of individuals in a group context (e.g., Donaldson, DeLeon, Fisher, & Kahng, 2014; Iwata & Bailey, 1974). In addition, these researchers have empirically evaluated preference for these procedures. However, few previous studies have evaluated the individual effects of these procedures both in group contexts and in the absence of peers. Therefore, we replicated and extended previous research by determining the individual effects and preferences of differential reinforcement and response cost under both group and individualized conditions. Results demonstrated that the procedures were equally effective for increasing on-task behavior during group and individual instruction for most children, and preference varied across participants. In addition, results were consistent across participants who experienced the procedures in group and individualized settings.

We study fluctuations in the drag force experienced by an object slowly moving through a 2D granular material consisting of bidisperse disks. Slow drag experiments provide a useful way to understand the nature of stress propagation, fluctuations, and slow dynamics in granular materials. Unlike in a liquid, the drag force in a granular material is largely due to the resistance of inhomogeneous and anisotropic ``force chains'', and thus exhibits strong fluctuations. Experiments were carried out in an apparatus similar in spirit to the one by Albert et al.(R. Albert, M.A. Pfeifer, A.L. Barabasi and P. Schiffer, Phys. Rev. Lett. 82), 205 (1999). and we varied the rotation rate (ω=6.3× 10-6 ˜ 8.7× 10-4Hz), the object size (0.744, 0.876, 1.250,1.610,1.930 cm), and the packing fraction of the system. We observed a weak dependence of the mean force on the medium velocity, a rate-invariant power spectrum decaying as ω-2 for large ω (a remarkable resemblance to results by Miller et al.(B. Miller, C. O'Hern and R.P. Behringer, Phys. Rev. Lett. 77), 3110 (1996).), an exponential distribution of avalanche sizes, and a well defined ``Stress Chain Force Constant''. We also show that a simple model adapted after Kahng. et al.(B. Kahng, I. Albert, P. Schiffer and A.L. Barabasi, Phys. Rev. E. 64), 051303 (2001). reproduces many of experimental observations.
We highlight key events in over 100 years of electronic amplifiers and their incorporation in computers and communication in order to appreciate the electron as man's most powerful token of information. We recognize that it has taken about 25 years or almost a generation for inventions to make it into new products, and that, within these periods, it still took major campaigns, like the Sputnik effect or what we shall call 10× programs, to achieve major technology steps. From Lilienfeld's invention 1926 of the solid-state field-effect triode to its realization 1959 in Kahng's MOS field-effect transistor, it took 33 years, and this pivotal year also saw the first planar integrated silicon circuit as patented by Noyce. This birth of the integrated microchip launched the unparalleled exponential growth of microelectronics with many great milestones. Among these, we point out the 3D integration of CMOS transistors by Gibbons in 1979 and the related Japanese program on Future Electron Devices (FED). The 3D domain has finally arrived as a broad development since 2005. Consecutively, we mark the neural networks on-chip of 1989 by Mead and others, now, 20 years later, a major project by DARPA. We highlight cooperatives like SRC and SEMATECH, their impact on progress and more recent nanoelectronic milestones until 2010.

the sheet resistance of HNO3 treated carbon-nanotube films than the removal of residual N-methylpyrrolidone. Unsurprisingly graphene, the latest carbon wonder material, has also shown remarkable potential as a transparent conducting film. Chemical vapour deposition (CVD) synthesis of graphene has the advantage that it allows fabrication of the sheets to be scaled up. A collaboration of researchers in the USA, Singapore and Korea demonstrated that the conductivity of CVD graphene sheets can be improved by p-doping with AuCl3 . The potential of graphene in a range of applications is also being demonstrated, as researchers in Australia and China show in a report on graphene in transparent conducting electrodes for GaN LED devices . The review in this issue  provides a comprehensive overview of graphene as an electrode, including the synthesis, chemical doping and work function engineering of the material, as well as applications in transistors, memories, molecular junctions, touch screens, LCDs, LEDs and solar cells. Back in the early 1950s Gillham and Preston saw the possibility of using their gold sputtered bismuth oxide films for windows that could be electrically heated and took out a patent on their discovery . While they saw potential applications for conducting transparent films, it could be argued that even Gillham and Preston would have been surprised at the extent to which transparent conducting films have infiltrated everyday technology over the 60 years since. It is tempting to wonder what wide reaching ramifications the current fruitful activity in graphene device research may have in the decades to come. References  Ayrton W E and Mather T 1894 J. Int.
