In spite of escalating efforts to curb abuse, fraud, and corruption in Congress, members of Congress persist in violating the norms, rules, and laws that aim to ensure they behave ethically. This chapter combines qualitative and quantitative analysis to describe congressional corruption in the modern era. Case studies illustrate consequential financial scandals while also differentiating four categories of corrupt financial practices.

Existing datasets on congressional scandals span the time period from 1972 to 2010, and this chapter extends the dataset to 2018. The analysis next uses the dataset to answer important questions empirically. Which types of scandals occur more often? Have these scandals grown more common or less common over time? What are the consequences of financial scandals for representatives' careers as public servants?

This paper examines the exercise of Black employee voice in South Africa over the past 53 years. Black workers constitute almost 4 out of every 5 workers in the country and experienced racial oppression from the time of colonisation up to the end of apartheid in 1994. They are still congregated around the lower skilled occupations with low incomes and high unemployment levels.

The paper draws on the theory of voice, exit and loyalty of Albert Hirschman, but extends voice to include sabotage as this encapsulates the nature of employee voice from about 2007 onwards. It reflects a culture of insurgence that entered employment relations from about that time onwards, but was lurking below the surface well before then.

The exercise of employee voice has gone through five phases from 1963 to mid-2016 starting with a silent phase for the first ten years when it was hardly heard at all. However, as a Black trade union movement emerged after extensive strikes in Durban in 1973, employee voice grew stronger and stronger until it reached an insurgent phase.

The phases employee voice went through were heavily influenced by the socio-political situation in the country. The reason for the emergence of an insurgent phase was due to the failure of the ruling African National Congress government to deliver services and to alleviate the plight of the poor in South Africa, most of whom are Black. The failure was due to neo-patrimonialism and corruption practised by the ruling elite and politically connected. Protests by local communities escalated and became increasingly violent. This spilled over into the workplace. As a result many strikes turned violent and destructive, demonstrating voice exercised as sabotage and reflecting a culture of insurgence.

The purpose of this chapter is to provide researchers a summary of some of the latest developments in item response theory (IRT), and to help these groups realize that psychometric tools can now be used for theory testing in addition to the traditional role of improving construct measurement. The author first reviews some of the fundamental tenets of classical test theory to contrast with IRT. He then describes recent advances in goodness-of-fit tests that have helped turn IRT into a model-testing tool. Finally, the author reviews several new test models that provide new flexibilities, summarizing summarize several examples of research that has used these new models in organizational research. At the end of this review, the author provides suggestions to help researchers better use these new IRT tools. Although there have been significant advances in IRT in the past decade, there has not been a systematic review of these developments. This review places those developments in context to provide readers a real appreciation of these breakthroughs.
