Four studies are reported on the structure of environmental attitudes. Based on Stern & Dietz’ (1994) value- basis theory for environmental attitudes, we predicted that concerns for environmental issues would form three correlated factors. The fir . . .

Thirty-one first-year psychology graduate students in a computer applications course completed a set of structured problems, unstructured problems, and data-screening problems in each of two statistical computing environments: a menu-based interface ( . . .

Recent research has examined the relationship between values and attitudes about environmental issues. Findings from these studies have found values of self-transcendence (positively) and self-enhancement (negatively) to predict general concern for en . . .

Prior research has explored the relationship between values, attitudes about environmental issues, and pro-environmental behavior. These studies have shown a consistent pattern of results—individuals who value self-transcendent life goals tend to care . . .

Electric-field-induced resistive switching in metal-oxide interfaces has attracted extensive recent interest. While many agree that lattice defects play a key role, details of the physical processes are far from clear. There is debate, for example, reg . . .

The kinetics of electric-field-induced resistive switching across metal ͑Ag͒-Pr0.7Ca0.3MnO3 interfaces has been investigated. The resistance hysteresis ⌬R varies with the pulse amplitude V0 roughly as a step function with existence of a threshold volta . . .

The existence of a negative static dielectric constant has drawn a great deal of theoretical controversy. Experimentally, one has never been observed. However, low-frequency negative capacitance has been widely reported in fields including physics, che . . .

We report on electric field induced bipolar resistive switching in metal electrode-Pr0.7Ca0.3MnO3 interfaces that exhibit hopping transport. The electrical transport data show that the number of hopping steps needed for a carrier to cross the interfaci . . .

Students in physics courses often use whiteboards to brainstorm, solve problems, and present results to the rest of the class, particularly in courses involving col-laborative small group work and whole class discussions. The whiteboards contain a val . . .

Resistive switching phenomena induced by electric pulsing have been investigated for several years as a result of interest in memory technology development. We investigate the viability of bipolar resistive switching at cryogenic temperatures by cooli . . .

A negative capacitance has been observed in a nanocolloid between 0.1 and 10−5 Hz. The response is linear over a broad range of conditions. The low-␻ dispersions of both the resistance and capacitance are consistent with the free-carrier plasma model, . . .

The polarity-dependent resistive switching across metal-Pr0.7Ca0.3MnO3 interfaces is investigated. The data suggest that shallow defects in the interface dominate the switching. Their density and fluctuation, therefore, will ultimately limit the device . . .

The significance of a negative dielectric constant has long been recognized. We report here the observation of a field-induced large negative dielectric constant of aggregates of oxide nano-particles at frequencies below ~ 1 Hz at room temperature. Th . . .

We investigate the polarity-dependent field-induced resistive switching phenomenon driven by electric pulses in perovskite oxides. Our data show that the switching is a common occurrence restricted to an interfacial layer between a deposited metal elec . . .

Pumping single electrons at a set rate is being widely pursued as an electrical current standard. Semiconductor charge pumps have been pursued in a variety of modes, including single gate ratchet, a variety of 2-gate ratchet pumps, and 2-gate turnstil . . .

Electrical transport in double quantum dots (DQDs) illuminates many interesting features of the dots' carrier states. Recent advances in silicon quantum information technologies have renewed interest in the valley states of electrons confined in silic . . .

Pauli-spin blockade (PSB) is a transport phenomenon in double quantum dots that allows for a type of spin to charge conversion often used to probe fundamental physics such as spin relaxation and singlet-triplet coupling. In this paper, we theoreticall . . .

Previous measurements of the superfluid density ρs and specific heat for 4He have identified effects that are manifest at distances much larger than the correlation length ξ3D [1–3]. We report here new measurements of the superfluid density which are . . .

We consider reliable facility location models in which facilities are subject to unexpected failures, and customers may be reassigned to facilities other than their regular facilities. The objective is to minimize the total expected costs in normal an . . .
