Research Questions

Purpose This paper aims to approach fundamental topics of financial crime and the law. What does constitute financial crime? Which field of law is best suited to address the threats of transgression by financial executives? What does motivate highly rewarded financiers to become white collar criminals? Design/methodology/approach To answer these research questions, contemporary theories of criminology in general and of white collar crime in particular, as well as theories on motivation, are critically discussed. Benefits and limitations of the theories in use are exemplified on the background of the London Interbank Offered Rate (LIBOR) scandal. Findings The paper criticises that the state-of-the-art theories are not able to embrace financial criminality in its entirety. A provoking pace for further research might be that of psychopathic disorders among white collar criminals. Thus, white collar crime maintains its challenging character. Originality/value This paper provides a thorough testing of multidisciplinary theories that emerged over the past decades against the recent LIBOR scandal. The research questions addressed and the methodologies applied provide a framework for the assessment of the prevailing theories against other financial scandals.

Purpose The purpose of this paper is to evaluate the experience of International Organization for Standardization (ISO) 9001 certified companies, examining their motivations to introduce the standard and their perceived benefits and barriers. In parallel, the research investigated the knowledge and perception of ISO 9004 guideline, analyzing if it could give an added value to certified companies. Design/methodology/approach A questionnaire was proposed by e-mail to 2,581 Italian ISO 9001 certified companies from January 18 to March 31, 2016; 522 companies participated to the survey. Findings Companies of different size have been driven by different motivations to certification, reaching different types of benefits, while both large and small ones perceived the greater bureaucratization as an obstacle. The ISO 9004 standard is little known and applied among Italian companies, but the ones which adopted it benefited from it. Research limitations/implications A limitation may be derived from the fact that the sample was composed only of Italian companies, although this effect was to understand perceptions and trends of these international standards in the Italian reality. Practical implications Analyzing perceived advantages and disadvantages of ISO 9001 and 9004 could be crucial for managers to understand if their joint use is the right strategy to gain competitiveness in the reference markets. Originality/value Compared to previous studies in which ISO 9001 was evaluated as a stand-alone standard, the research made a comparative evaluation with ISO 9004, as ISO considers them to be “consistent pair of standards,” covering the literature gap about the effectiveness of the joint use of them.

The requirements on gratings and coatings for astronomical use differ from the general industrial requirements primarily in the scale of the components to be fabricated. Telescopes have large primary mirrors which require large coating plants to handle the components. Dispersive elements are driven by the requirement to be efficient in the presence of large working apertures, and usually optimize to large size in order to efficiently use the incoming radiation. Beyond this, there is a “new” technology of direct electronic sensors that places specific limits upon the image scale that can be used at the output of a telescope system, whether direct imagery or spectrally divided imagery is to be examined. This paper will examine the state of the art in these areas and suggest some actions and decisions that will be required in order to apply current technology to the predicted range of large new telescopes.
