A half‐implicit absolutely stable method for 3D simulation of the transient processes in semiconductor devices is proposed. The calculations of transient processes in bipolar transistor were carried out and were compared with the results of 2D simulation.

An efficient numerical method for the solution of hot‐carrier transport equations describing transient processes in submicrometer semiconductor devices is proposed. The calculations of transient processes in submicrometer MOS transistor were carried out and compared with the results obtained by conventional drift‐diffusion model.

We discuss three models describing the carrier densities in highly doped silicon, which have been used for process and device simulation. We calculate nie for each of the models for various doping concentrations within temperature ranges interesting for the device and process simulation. We try to explain the behaviour of nie for high compensation and compare our calculated results to measured values of nie. We offer simple formulae for the calculated nie and show how far the relations between the carrier densities and the Fermi levels can be described by the simple formulae of Boltzmann statistics when we use a doping dependent effective intrinsic number.

A general algorithm for analysis of semiconductors with arbitrary models for heavy doping phenomena is presented. Different models, theoretical as well as empirical, were applied, and minority carrier concentration in the uncompensated n‐type silicon was analyzed. Recalculated into the term of apparent BGN, the results were compared with experimental data. Further analysis of apparent BGN indicated the weakness of empirical formulae for apparent BGN. Assumption of total ionization of impurities considered in the analysis is discussed and justified.

Enhanced efficiency of the proposed modification of the Gummel decoupled method enables significant reduction of memory requirements in comparison to the conventionally used Newton‐like methods with approximately equal CPU time expense. For 10,000 mesh nodes it only requires 4.4 Mbytes of virtual memory (compare to 62 Mbytes for PISCES‐2B). The method exhibits good stability and convergence rate and has significant advantages compared to the other often used half‐implicit scheme. Low memory requirements and efficiency make the method attractive for future 3‐D applications.

Rapid inflation, the severe reduction in demand for cars and the resultant over‐capacity, reestablished the importance of price as a competitive weapon in the car market between late 1973 and 1977. In times of steady economic growth the over‐whelming influence of changes in per capita income on car demand tends to relegate the price variable to a secondary position, and often it is almost totally discounted as a major causative variable. However, in a number of ways the state of the market in the mid 1970s has shown the continuing importance of relative prices: the pricing of imports, exports and price competition by domestic manufacturers all being geared to improving a manufacturer's market penetration. Consequently, the pricing decision remains as one of the most important features of competitive strategy and as a major factor in managerial decision making.

This chapter focusses on food systems' vulnerability. In a rapidly and unpredictably changing world, vulnerability of farming and food systems becomes a key issue. The conceptual bases for food vulnerability analysis and food vulnerability assessment are discussed in a systemic perspective with an eye to the transition approach (Geels, 2004) as a perspective capable to analyze how novelties can develop and influence the system capability to fulfil societal functions, and food and nutrition security in particular. A framework for assessing people's food vulnerability is presented together with a simple vulnerability model based on the three dimensions of exposure (the degree to which a system is likely to experience environmental or sociopolitical stress), sensitivity (the degree to which a system is modified or affected by perturbations) and adaptive capacity (the ability to evolve in order to accommodate environmental hazards or change) (Adger, 2006). Then, other sections are dedicated to discuss the general questions that should be answered by a vulnerability assessment exercise, and the specific challenges emerging when the assessment concerns a food system. These elements are then used in the Annex to this chapter as a base for the development of a detailed method based on seven distinct steps for conducting participatory assessments of the vulnerability of food systems.

The key purpose of this chapter is to identify some ways of enhancing feminist conceptual, empirical, and theoretical work on violence against women. Much attention is given to addressing the harms caused by new electronic forms of woman abuse, including the role of adult Internet pornography and sex robots. This chapter also emphasises the importance of revisiting some major feminist contributions from the past.

The monetary policy implementation and corporate investment are closely intertwined. The aim of modern monetary policy is to mitigate economic fluctuations and stabilise economic growth. One of the ways of influencing the real economy is influencing the level of investment by enterprises.

This chapter provides evidence on how monetary policy affected corporate investment in Poland between 1Q 2000 and 3Q 2022. We investigate the impact of Polish monetary policy on investment outlays in contexts of high uncertainty.

Using the correlation analysis and the regression model, we show the relation between the monetary policy and the investment outlays of Polish enterprises. We used the least squares method as the most popular in linear model estimation. The evaluation includes model fit, independent variable significance and random component, i.e. constancy of variance, autocorrelation, alignment with normal distribution, along with Fisher–Snedecor test and Breusch–Pagan test.

We find that Polish enterprises are responsive to changes in monetary policy. Hence, the corporate investment level is correlated with the effects of monetary policy (especially with the decision on the central bank's basic interest rate changes). We found evidence that QE policy has a positive impact on Polish investment outlays. The corporate investment in Poland is positively affected by respective monetary policies through Narodowy Bank Polski (NBP) reference rate, inflation, corporate loans, weighted average interest rate on corporate loans.

There is a huge amount of social and educational research concerned with various kinds of inequality. Much of this research assumes that inequalities are a bad thing, even when it is solely concerned with providing information about the level and causes of inequalities of some particular kind.¹ Sometimes, however, this use of crude egalitarianism spills over into presentation of what can be read as practical value judgements. Ambiguity between factual conclusion and practical evaluation is frequently exploited, or at least allowed to prevail. As a result, evaluations seem to be expressed, and/or prescriptions for action proposed, with the implication that they are justified by research evidence. Yet, on its own, research evidence can rarely provide a sufficient justification for value conclusions (see Foster et al., 2000; Hammersley, 2003a). While on some occasions research evidence may be treated as pointing directly to value conclusions, there are always value premisses involved, as well as factual ones, and these will often be open to reasonable doubt and disagreement.
