Characterization and differentiation of cyclopropylfentanyl from E-crotonylfentanyl, Z-crotonylfentanyl,and 3-butenylfentanyl

Recently, a sample containing cyclopropylfentanyl was analyzed at this laboratory. Cyclopropylfentanyl began to appear in the United States' illicit drug markets in 2017. Unfortunately, cyclopropylfentanyl presents an analytical challenge due to its mass spectrum being almost identical to that of crotonylfentanyl. There are two possible isomers of crotonylfentanyl, Z- and E- crotonylfentanyl. In order to provide sufficient analytical data to distinguish the two isomers of crotonylfentanyl and cyclopropylfentanyl, crotonylfentanyl was synthesized and fully characterized. Each isomer was analyzed via nuclear magnetic resonance spectroscopy, gas chromatography–mass spectrometry, and Fourier transform infrared spectroscopy. During the synthesis of crotonylfentanyl, an unknown compound was formed. The identification of this compound and the analytical characterization of the two isomers of crotonylfentanyl are presented. Through the comparison of these compounds, it was confirmed that cyclopropylfentanyl can be differentiated from crotonylfentanyl.     

The security of access to accounts under the PSD2

The revised Payment Services Directive (‘PSD2’) has been adopted to stimulate the development of an integrated internal market for payment services. In particular, it facilitates payment initiation services and account information services by granting the providers of these services access to the accounts of the payment service users. At the same time, the recitals state that the PSD2 guarantees a high level of consumer protection, security of payment transactions and protection against fraud.This paper answers the following question: To what extent does the access to accounts of the payment initiation service providers and account information service providers balance the development of the market for payment services with the security of the payment account and the privacy of the user? An analysis of the PSD2 shows that the development of the market for payment services has a higher priority. Security and privacy are ultimately subordinate.First, the PSD2 does not adequately protect the personal data of the users. The definition of ‘account information service’ is broad and covers a wide range of services. This allows the payment service providers to circumvent the limitations of the access to accounts.Next, the payment service providers have a ‘fall back option’ that allows ‘screen scraping’ if the dedicated interface is not functioning properly. Although this access is constrained by several safeguards, the fall back option gives the payment services provider unlimited access to the account of the user.Finally, the payment service providers have considerable freedom to arrange their authentication process as they see fit. The banks seem to be required to trust this process. The PSD2 and regulatory technical standards do not demand that a bank is able to verify the authentication or the integrity of the payment order.     

The importance of dark adaptation for forensic examinations; an evaluation of the Crime-lite Eye™

Forensic practitioners are recommended to dark adapt their eyes prior to conducting evidential searches in the dark. The dark adaptation process remains poorly standardised across the discipline, with little quantified regarding the benefits of such preparative steps. Herein, we report the findings of a study that recruited 50 participants to assess the effectiveness of the Crime-lite Eye?, a darkness adaptation device developed to assist forensic practitioners both in the laboratory and in field. Participants were tasked with searching for the fluorescent signatures left by reaction of 1,8-diazafluoren-9-one (DFO) with amino acids, in a manner akin to the fluorogenic fingerprint treatment of porous evidence. Using an Epson Stylus Photo R265 inkjet printer, ink cartridges were filled with alanine solutions of various concentrations, allowing different motifs to be printed onto copy paper and subsequently developed using DFO. Participants searched for this ‘evidence’ both with and without dark adapted vision. On average, participants were able to locate and correctly recognise 16% more evidence once dark adapted using the Crime-lite Eye?.The increase in evidence located by participants once dark adapted suggests that crime scene officers should be dark adapting in order to visualise as much as possible. The time taken to dark adapt, 10?min on average during this study, is not excessively long, and should not significantly slow the investigation.     

Understanding the political goals of non-binding resolutions: evidence from the Mexican Chamber of Deputies

By primarily focusing on bill initiatives, the literature on legislatures and parliaments has understudied other important legislative instruments -such as non-binding resolutions, minutes or speeches- which might help parties and legislators achieve their electoral and policy goals. Non-binding resolutions (NBRs) do not carry the force of law and are primarily used for parties or legislators’ position taking and the request of government actions. This article examines the political goals of NBRs by examining these tools in the lower chamber of the Mexican Congress. Employing a novel dataset, we claim that legislators strategically utilise NBRs to strengthen their relationship with their political principals. We find differences on the use of these instruments across political parties, based on the types of policy areas they choose to target. The analysis also indicates that SMD legislators tend to introduce more particularistic NBRs that might further their political careers at the subnational level.

The New Zealand Model of Family Group Conferencing

The Family Group Conference (FGC) originated in New Zealand where it is the foundation stone of the Youth Justice system introduced in 1989. A significant feature of that system is the way in which it enables restorative justice principles to be implemented in an integrated manner in a statutory framework supervised by the courts and applicable to all young offenders throughout New Zealand. FGCs are used both as a diversionary technique (pre-adjudication) and at a (post-adjudication) pre-sentencing stage. In addition this type of model is now being applied in a voluntary way but on a small scale with adults. A significant feature of the FGC model is its greater use of community-based solutions with a consequent reduction in the number of young persons in state institutions.     

To be continued . . . Syntheses and trends in follow-up of quality assurance in West European higher education

The authors report on West European trends in follow-up arrangements of national quality assurance procedures. They argue that external quality assurance ought to adopt a broader conception of quality than is now often the case. Next, the general public ought to have a guarantee that external quality assurance is valid (through meta-evaluation) and has consequences (through follow-up arrangements). Follow-up currently is not well developed in many European countries in a formal sense, but is receiving more attention as external quality assurance is maturing. Finally, the authors link national quality assurance to the European dimension; an international network could fulfil important functions in making quality assurance transparent and credible across Europe. This revised version was published online in August 2006 with corrections to the Cover Date.     

Age assessment by rib phase analysis in Turks

The I?can's phase method for the estimation of adult age at death from the sternal extremity of the fourth rib was introduced in 1983. Over the years, numerous tests have confirmed the reliability of this technique on varied samples. However, no large scale study has been conducted to test the application of this method on a modern white sample geographically, genetically, and culturally diverse from the American white database. Therefore, the purpose of this paper is to apply rib phase standards to a Turkish sample to test if the progression of morphological changes follow the same age sequence. Using a sample of 150 males and 144 females of known age at death, each rib was phased using the standards developed by I?can and associates in 1984 and 1985. The phase estimations were then subject to an analysis of variance. The results of the study indicated that Turkish ribs show the same morphological characteristics that define the phases at nearly identical ages. Variation as measured by the standard deviation increased from phase 5 on in both sexes. In conclusion, this study demonstrated that the rib phase standards can be accurately applied to Turks. Investigations of this nature are vital because one cannot assume that a method developed from one group is applicable to a distant population, especially in medicolegal proceedings.
