Inhibitory Conditioning

Three experiments studied inhibitory conditioning in an unsignalled shuttlebox-avoidance preparation with rats. Following a Pavlovian conditioning phase and using a summation test in which test stimuli were superimposed on a previously established ongoing shuttlebox-avoidance response, it was found in Exp. 1 that a light could be established as an inhibitor of avoidance when it signalled the absence of shock. Exp. 2 established that a light could become a conditioned inhibitor when it signalled a reduction in shock intensity rather than its complete absence. Exp. 3 confirmed this general finding but did not yield differential inhibitory effects with different degrees of reduction in shock intensity for the particular parameters chosen. The findings can be adequately interpreted in terms of the Rescorla-Wagner model of conditioned inhibition.

Higher Sensitivity

A study of the dynamics of preservation of the conditioned reflex of passive avoidance (passive avoidance response) in rats of two lines with different level of excitability of the nervous system was performed: with a high and low thresholds of excitability as normal and after exposure to sodium thiopental semi-lethal dose. It was shown that a long preservation of the memorable trace under standard conditions and a higher sensitivity to the sodium thiopental action manifest in rats with a high excitability threshold in comparison with low-excitable line of rats.

AbstractThe sporangiophores of Phycomyces blakesleeanus have been used as a model system to study sensory transduction, helical growth, and to establish global biophysical equations for expansive growth of walled cells. More recently, local statistical biophysical models of the cell wall are being constructed to better understand the molecular underpinnings of helical growth and its behavior during the many growth responses of the sporangiophores to sensory stimuli. Previous experimental and theoretical findings guide the development of these local models. Future development requires an investigation of explicit and implicit assumptions made in the prior research. Here, experiments are conducted to test three assumptions made in prior research, that (a) elongation rate, (b) rotation rate, and (c) helical growth steepness, R, of the sporangiophore remain constant during the phototropic response (bending toward unilateral light) and the avoidance response (bending away from solid barriers). The experimental results reveal that all three assumptions are incorrect for the phototropic response and probably incorrect for the avoidance response but the results are less conclusive. Generally, the experimental results indicate that the elongation and rotation rates increase during these responses, as does R, indicating that the helical growth steepness become flatter. The implications of these findings on prior research, the “fibril reorientation and slippage” hypothesis, global biophysical equations, and local statistical biophysical models are discussed.

The Impact

Risk is a condition caused by uncertainty. Risks will occur on any construction project, including bridge construction projects. Efforts that can be taken to minimize the impact of these risks are to engage in risk management activities. This research was conducted on bridge construction work on toll road procurement project in Pejagan-Pemalang, Pemalang-Batang and Salatiga-Kertasura. The purpose of this research is to analyze the risk of bridge development project in toll road project using Risk Breakdown Structure (RBS) method and then the result as database in discussing risk response strategy. The bridge construction project has 36 risks that are divided into six groups: materials and equipment, design, human resources, finance, management, nature and environmental conditions. Bad weather risks are the higest risk and seasonal risk causing temporary work stoppages. This risk-response strategy is avoidance. Short-term avoidance response strategy is to add shift workers, install tents and add additives in the acceleration of the process of maturation of concrete. The long-term avoidance response strategy is to evaluate and rearrange the work schedule by considering the weather forecast report.
