Champions of the poor or “militant fighters for a better pay cheque”? Teacher unionism in Mexico and South Africa, 1979–2013

There are some fascinating historical parallels between Mexico’s giant teacher union, the Mexican National Education Union, and the South African Democratic Teachers Union. Although both teacher unions played an important role in challenging political oligarchies at certain points in their history, they became increasingly protectionist. Through their close affiliation to ruling parties, they were able to wield substantial political influence. In both of these cases, the unions played a controversial role in preventing central government surveillance and intervention in schools. Arguably, this often allowed not only for corruption in appointments and promotions, but also the protection of negligent teachers. There is some evidence to suggest that in protecting their sectional interests, both unions have frequently alienated parents and students at the community level. This paper addresses broader debates about the impact of powerful teacher unions on the quality of public schooling.     

Economics of Polluter Pays Principles for Mitigating Social Costs of Electricity: A Search for an Optimal Liability Share

To deal with externalities associated with electricity generation, under the Polluter Pays Principles (PPP), companies can be made to pay the compliance costs and then pass these costs incurred on to the end-users by charging a higher price per kWh of electricity used. However, there is a need for an optimal liability scheme, in terms of economic efficiency, equity and ethics in a world of favor seeking politics. With implicit weighting of welfare gains and losses to society, we developed supply-demand models. By incorporating plausible parameter values into the models, the optimal liability shares fell to less 100 percent (full) liability. However, the model is very sensitive to changes in the parameter values.     

The 1998 Northern Ireland Assembly Election

The result of the assembly election in Northern Ireland in June 1998 was a victory for those who support the assembly, but it was not such a triumph for David Trimble and the Ulster Unionist Party. I will examine both the Unionist vote and the Nationalist vote and the consequences.     

Evaluation of GLOCK 9 mm Firing Pin Aperture Shear Mark Individuality Based On 1,632 Different Pistols by Traditional Pattern Matching and IBIS Pattern Recognition

Over a period of 21 years, a number of fired GLOCK cartridge cases have been evaluated. A total of 1632 GLOCK firearms were used to generate a sample of the same size. Our research hypothesis was that no cartridge cases fired from different 9‐mm semiautomatic GLOCK pistols would be mistaken as coming from the same gun. Using optical comparison microscopy, two separate experiments were carried out to test this hypothesis. A subsample of 617 test‐fired cases were subjected to algorithmic comparison by the Integrated Ballistics Identification System (IBIS). The second experiment subjected the full set of 1632 cases to manual comparisons using traditional pattern matching. None of the cartridge cases were “matched” by either of these two experiments. Using these empirical findings, an established Bayesian probability model was used to estimate the chance that a 9‐mm cartridge case, fired from a GLOCK, could be mistaken as coming from the same firearm when in fact it did not (i.e., the random match probability).     

Plea decision-making by attorneys and judges

Objectives

Approximately 95 % of convictions in the United States are the result of guilty pleas. Surprisingly little is known about the factors which judges, prosecutors, and defense attorneys consider in these decisions. To examine the legal and extralegal factors that legal actors consider in plea decision-making, we replicated and improved upon a 40-year-old study by asking legal actor participants to review a variety of case factors, and then make plea decisions and estimate sentences for pleas and trials (upon conviction).

Methods

Over 1,500 defense attorneys, prosecutors, and judges completed an online survey involving a hypothetical legal case in which the presence of three types of evidence and length of defendant criminal history were experimentally manipulated.

Results

The manipulated evidence impacted plea decisions and discounts, whereas criminal history only affected plea discounts (i.e., the difference between plea and trial sentences). Defense attorneys considered the largest number of factors (evidentiary and non-evidentiary), and although legal actor role influenced the decision to plead, it did not affect the discount.

Conclusions

In replicating a landmark study, via technological advances not available in the 1970s, we were able to increase our sample size nearly six-fold, obtain a sample representing all 50 states, and include judges. However, our sample was nonrepresentative and the hypothetical scenario may or may not generalize to actual situations. Nonetheless, valuable information was gained about the factors considered and weighed by legal actors.

     

Corporate Psychopaths and organizational type

This paper looks at one of the members of the ‘dark triad’ of managers with malevolent personalities and investigates whether Corporate Psychopaths are to be found at greater levels of incidence in any particular type of organization. The paper introduces the topic of research into the characters of leaders and explains why this is important. It then discusses who Psychopaths and Corporate Psychopaths are in comparison with the other members of the ‘dark triad’; Machiavellians and Narcissists. The paper discusses some of the theoretical implications of having Corporate Psychopaths in organizations and then presents some evidence that they are to be found at greater incidence levels in financial service institutions and the civil service rather than in primary industries and retail services. The paper looks at the implications of the presence of Corporate Psychopaths in terms of lower levels of corporate social responsibility and mentions that Corporate Psychopaths also influence productivity and organizational constraints.
