Video recordings of free behavior and responses to mechanical facial stimulation were analyzed to assess whether chronic constriction injury (CCI) to the rat's infraorbital nerve (IoN) results in behavioral alterations indicative of neuropathic pain. A unilateral CCI was produced by placing loose chromic gut ligatures around the IoN. After CCI to the IoN, rats exhibited changes in both non-evoked and evoked behavior. Behavioral changes developed in two phases. Early after CCI (postoperative days 1–15), rats showed increased face-grooming activity with face-wash strokes directed to the injured nerve territory, while the responsiveness to stimulation of this area was decreased. Later after CCI (postoperative days 15–130), the prevalence of asymmetric face grooming was reduced but remained significantly increased compared to control rats. The early hyporesponsiveness was abruptly replaced by an extreme hyperresponsiveness: all stimulus intensities applied to the injured nerve territory evoked the “maximal” response (brisk head withdrawal, avoidance behavior plus directed face grooming). This response was never observed in control rats. Concurrently, IoN ligation rats showed a limited increase in the responsiveness to stimulation of the contralateral IoN territory, and around postoperative days 30–40 the responsiveness to stimulation of facial areas outside the IoN territories also increased. The hyperresponsiveness to stimulation of the ligated IoN territory slightly decreased from 60 d postoperative. Throughout the study, IoN ligation rats showed decreased exploratory behavior, displayed more freezing-like behavior, had a slower body weight gain, and a higher defecation rate, compared to control rats. The behavioral alterations observed after CCI to the IoN are indicative of severe sensory disturbances within the territory of the injured nerve: mechanical allodynia develops after a period of relative hypo- /anesthesia during which behavioral signs of recurrent spontaneous, aversive (possibly painful) sensations (paresthesias/dysesthesias) are maximal.

Power to Detect Differences between Alternative Treatments in Comparative Psychotherapy Outcome Research.

Poor ethical decision–making costs industry billions of dollars a year and damages the images of corporations. Thus, by answering the question ‘Why do individuals behave as they do when confronted with ethical issues?’ ethical theory can provide businesses with a means to create a more ethical climate and a more successful operation. This study tested the Ethical Decision–Making Model with accountability (Beu & Buckley 2001), which uses theory that suggests that ethical behavior is influenced by the individual, the issue, social relationships (accountability), and the organization in which the employee is embedded (Brass, Butterfield & Skaggs 1988; Frink & Klimoski 1998). The results showed that individuals’ thought processes (cognitive moral development), personalities (locus of control, hostility and aggression, Machiavellianism), and gender influence how they respond to ethical dilemmas, as well as the salience of the moral issue (moral intensity) and the environmental context (work/school).

Ethical decision–making: a multidimensional construct

Self assessment system (SAS) has become the key administrative approach for both personal and corporate taxation in developed countries including the USA, UK and Australia. This approach emphasises both the taxpayers’ responsibility to report their income and the need for them to determine their own tax liability. Central to the motivations of self assessment system introduction is an increase in the efficiency of tax collection for the tax authority; however, of more vital importance is the need to enable this without having an unacceptable detrimental effect on the other key characteristics of a well-designed tax system (equity, wider administrative efficiency etc). This requires the development of public awareness of tax laws, and improvements in voluntary compliance. According to prior studies on this topic one of the main facilitating factors in achieving these aims is the development of the level of tax knowledge among taxpayers. The objective of this study is to investigate how facilitating factors interact in the development of a suitable SAS focusing in particular on the role of tax knowledge. To explore the interaction in the real setting the country of Malaysia is used as a case tax system for this study. This country is due to chosen its fairly recent introduction of SAS enabling a specific focus on changes brought about by the move to a SAS with as little time for ‘noise’ creating factors as possible that may result from longer implemented SAS. It also enables a study of this topic in the context of a developing country where many of the prior studies in this area have had in the context of developed countries. This study focuses on the level of individual Malaysian taxpayers’ knowledge and explores how tax knowledge levels influence tax compliance behaviour in a new SAS. Data was collected through a large scale national postal survey resulting in 1,073 responses. Five stages were used to facilitate the analysis. Stage 1, using the t-test and ANOVA, focuses on the characteristics of taxpayers’ knowledge including gender, ethnicity, educational level and income level. Stage 2 attempts to describe the relationship between tax knowledge and tax compliance using multiple regressions. Stage 4 examines taxpayers’ compliance determinants more widely than tax knowledge. Nine variables were tested in Stage 4. Control variables were added in both Stage 3 and Stage 5 in order to assess whether the inclusion of control variables significantly affects tax compliance behaviour. The results suggested that tax knowledge has a significant impact on tax compliance even though the level of tax knowledge varies significantly among respondents. The results also indicate that tax compliance is influenced specifically by probability of being audited, perceptions of government spending, penalties, personal financial constraints, and the influence of referent groups. Results of this study answer such questions as which various taxpayer characteristics of tax knowledge affect compliant behaviour. The results of this study can inform policymakers on the extent to which tax knowledge is important in a self assessment system and in what ways it can affect compliance. It also provides an indicator for tax administrators of the relative importance of tax knowledge in assisting with the design of tax education programmes, simplifying tax systems and developing a iii wider understanding of taxpayers' behaviour. This study contributes to current global literature in this field of the relative importance of tax knowledge in affecting tax compliance, as well as exploring the factors that make people pay taxes in a self assessment system, and discusses methods of increasing voluntary compliance.

A recurring problem in behavioral science research is that of determining the appropriate sample size before conducting a research investigation. The more common approaches to this problem have been to apply indiscriminantly the formulae used in survey research without considering the factors necessary for using these formulae. The most important of these factors is the Effect Size. In this paper, tables for the appropriate sample sizes are presented and discussed in the context that the determination of the Effect Size must precede the determination of the sample size.
