Trace analysis of peroxide explosives by high performance liquid chromatography-atmospheric pressure chemical ionization-tandem mass spectrometry (HPLC-APCI-MS/MS) for forensic applications

An HPLC-APCI-MS(/MS) method for the (trace) analysis of the most commonly encountered peroxide explosives, hexamethylenetriperoxidediamine (HMTD) and triacetonetriperoxide (TATP), has been developed. With this method, HMTD and TATP have been analyzed in the same run. (Pseudo-)molecular ions of these peroxides have been obtained as base peak under the same condition. A series of product ions was produced from these pseudo-molecular ions ([HMTD - 1]+ and [TATP + NH4]+) in the MS/MS analysis. We also pioneered in showing that a TATP molecular ion [TATP + H]+ can be observed with HPLC-MS/MS. The limit of detection for HMTD and TATP was 0.26 and 3.3 ng, respectively, on column by HPLC-MS in the Full Scan mode and 0.08 and 0.8, respectively, by HPLC-APCI-MS/MS in Selected Reaction Monitoring (single mass unit) mode. The method presented has been applied successfully for the identification of peroxides in the bulk solid state (powder sample), as well as in post-blast extracts originating from a forensic case. For the post-blast extracts, the use of tandem MS has been shown clearly to be of crucial importance for the identification and detection of the peroxide explosives.     

Explaining Regulatory Non-compliance: A Survey Study of Rule Transgression for Two Dutch Instrumental Laws, Applying the Randomized Response Method

Within a rational choice framework, secondary data analysis of a survey study on compliance with two Dutch regulatory laws is carried out. Selection of explanatory variables to be considered is guided by a heuristic device, called the Table-of-Eleven. Using adapted logistic regression analysis, we show that self-reported compliance, measured by means of a randomized response procedure, can be explained in terms of benefits of non-compliance, social norms and deterrence, while knowledge and general norm-conformity have no role to play. The impact of various contributing factors turns out to be rather different in size for the two laws.     

What Patent Data Reveal about Universities: The Case of Belgium

In recent years, there has been a surge in patenting by Belgian universities. It appears that this increase can be attributed to growth of biotechnology, where there is a greater propensity to patent, to a desire on the part of universities to enhance commercialization through technology transfer offices (TTOs), and to effective collaboration between universities and government-sponsored research centers. Our qualitative analysis reveals that patent statistics could be a misleading indicator of an individual university's technological productivity, since many inventions are developed at universities, yet applied by other institutions.

Allele frequency distribution for 21 autosomal STR loci in Bhutan

We studied the allele frequency distribution of 21 autosomal STR loci contained in the AmpFlSTR^® Identifiler™ (Applied Biosystems), the Powerplex^®16 (Promega) and the FFFL (Promega) multiplex PCR kits among 936 individuals from the Royal Kingdom of Bhutan. As such these are the first published autosomal DNA results from this country.     

Industrial Relations and Public Sector Reform: The Victorian Case

Few anticipated the radical program of public sector reform introduced by the Kennett government. A commitment to downsizing, markets and privatisation has transformed employment relations in the Victorian public sector. Familiar institutions have disappeared, major employment areas have been restructured, and jurisdiction for much public sector industrial relations has been transferred to the Commonwealth. Despite some industrial unrest, and occasional successes, public sector unions have been unable to fend off this ideological assault on traditional patterns of public sector employment.     

Minimizing culpability increases commission errors in a mock crime paradigm

Purpose. Empirical studies have demonstrated that feigning amnesia undermines memory for a mock crime. Not much is known about the effects of other culpability‐reducing strategies on memory. The present study investigated what strategies participants use when they are instructed to minimize culpability and if these strategies undermine memory to a similar extent as claiming amnesia. Methods. Participants performed a mock crime. Next, they were either instructed to minimize culpability for this mock crime in a simulated interrogation or asked to respond honestly. One week later, memory for the mock crime was tested. Results. None of the participants claimed amnesia when trying to minimize culpability. Conversely, all participants fabricated an alternative account of their role in the crime. Compared with responding honestly on both tests, fabricating an alternative story on the first test undermined memory for the mock crime in terms of commission errors. Correct recall was unaffected. It appeared that this effect was related to story length: the longer the fabricated story, the more the commission errors when telling the truth 1 week later. Conclusions. Fabricating an alternative story (i.e. lying) did not compromise correct recall, but induced more commission errors. The findings are discussed in terms of possible underlying mechanisms.
