Using Cluster Analysis and ICP‐MS to Identify Groups of Ecstasy Tablets in Sao Paulo State,Brazil

The variations found in the elemental composition in ecstasy samples result in spectral profiles with useful information for data analysis, and cluster analysis of these profiles can help uncover different categories of the drug. We provide a cluster analysis of ecstasy tablets based on their elemental composition. Twenty‐five elements were determined by ICP‐MS in tablets apprehended by Sao Paulo's State Police, Brazil. We employ the K‐means clustering algorithm along with C4.5 decision tree to help us interpret the clustering results. We found a better number of two clusters within the data, which can refer to the approximated number of sources of the drug which supply the cities of seizures. The C4.5 model was capable of differentiating the ecstasy samples from the two clusters with high prediction accuracy using the leave‐one‐out cross‐validation. The model used only Nd, Ni, and Pb concentration values in the classification of the samples.     

Origin,Analytical Characterization,and Use of Human Odor in Forensics

Developing a strategy to characterize the odor prints of individuals should be relevant to support identification obtained using dogs in courts of justice. This article proposes an overview of the techniques used for the forensic profiling of human odor. After reviewing the origin of human odor—both genetic and physiological—the different analytical steps from sample collection to statistical data processing are presented. The first challenge is the collection of odor, whether by direct sampling with polymer patches, cotton gauze, etc., or indirect sampling with devices like Scent Transfer Unit. Then, analytical techniques are presented. Analyses are commonly performed with gas chromatography coupled with mass spectrometry. As they yield large amounts of data, advanced statistical tools are needed to provide efficient and reliable data processing, which is essential to give more probative value to information.     

Legal Pluralism,Gendered Discourses,and Hybridity in Land‐titling Practices in Cambodia

This article describes and analyses the tensions, ambivalence, and hybridity that prevail in the nexus between discourses of gender and the legal pluralism of the new, formalized, and customary ways of handling land titles. Based on empirical research in Cambodia, it reveals a number of mechanisms, challenges, and inconsistencies in the practice of land‐titling. Foremost, the practice of titling seems to be highly informed by local discourses of marriage, family, gender, and age, which all affect to whom land is assigned; this leaves a hybrid construction in the nexus between statutory law and customary practices. The article departs from this observation and adds three contributions – on a theoretical level – to existing research: by incorporating the dimensions of discourse analysis and legal hybridity, by linking the concept of legal pluralism to the process of hybridization, and by introducing the notion of hybridity of implementation as a supplement to hybridity of law.     

Intimate Partner Violence in Turkey: The Turkish Intimate Partner Violence Attitude Scale-Revised

This study documents psychometrics of the Turkish version of Intimate Partner Violence Attitude Scale-Revised (IPVAS-R; Fincham et al. in Psychological Assessment, 20, 260–269, 2008). Dating college students (n=280) from four universities completed Turkish versions of the IPVAS-R, Multidimensional Measure of Emotional Abuse, Physical Assault of Conflict Tactics Scale - Revised, and Ambivalent Sexism Inventory. Confirmatory factor analysis supported the three factor structure of the IPVAS-R, albeit with an item change from the Abuse to the Control factor, due to the cultural nuances. This factor structure was cross validated with a second independent sample of 205 dating college students. Convergent validity and satisfactory internal consistency were also reported. The IPVAS-R was found to be a psychometrically sound measure to gauge attitudes toward psychological and physical dating aggression among college students outside of North America.     

A Brief History of Arts Marketing Thought in North America

Marketing is a relatively new academic discipline. Arts marketing as a subfield of marketing began in the 1960s. Sociologists and economists were the first to contribute to the knowledge. American authors then stepped in the late 1970s to the 1990s. Starting in the 2000s, European as well as Australian colleagues took the lead in terms of number of articles published. Currently, academic research by marketing scholars is enriching this new field of inquiry on consumer behaviors and on the four traditional P's of marketing: product (and brand), price, place, and promotion.     

A Comparison of Invalidating Family Environment Characteristics Between University Students Engaging in Self-Injurious Thoughts &; Actions and Non-Self-Injuring University Students

Individuals experiencing non-suicidal self-injurious (NSSI) thoughts only are greatly overlooked by current research. This investigation aimed at determining how three groups of university students differed in their reported quality of childhood relationships with parents, and histories of physical and sexual abuses. These groups included students experiencing only NSSI thoughts (n = 126), students engaging in NSSI actions (n = 90), and students exhibiting neither (n = 1,080). Results showed that individuals experiencing NSSI thoughts only, and those engaging in NSSI actions reported poorer relationships with parents and more physical abuse than the No NSSI group; however, NSSI thoughts and NSSI action groups had similar outcomes to one another for most variables. These findings suggest that individuals experiencing only NSSI thoughts share similar negative childhood environments associated with engagement in NSSI action and that they should be included in future research, particularly investigations aimed at identifying protective factors that could prevent them from engaging in NSSI.     

Overcoming Clientelism Through Local Participatory Institutions in Mexico: What Type of Participation?

This article addresses the relationship between institutionalized citizen participation at the municipal level and clientelism. It argues, contrary to what the literature has suggested, that the institutionalization of local citizen participation does not necessarily lead to the erosion of clientelism. Drawing on a comparative case study of participatory experiences in two Mexican municipalities, León and Nezahualcóyotl, this study argues that participation does matter, but that not all types of participation have the same effect on state‐society relations. Institutional design is important in assessing the significance of popular participation in defining the relationship between the state and its citizens, but informal practices are even more important determinants of citizens' level of autonomy in institutionalized participatory mechanisms. This level of autonomy, in turn, determines the potential for such local institutions to become a means to overcome clientelism as the mechanism traditionally characterizing state‐society relationships in Mexico.     

Delegation and Institutional Design in Health‐Care Rationing

The delegation of decision‐making powers to nonmajoritarian, independent agencies has become a significant phenomenon in more and more policy areas. One of these is the health‐care sector, where decisions on the range of services covered within public systems have, in most developed countries, been delegated to specialized bodies. This article offers an analytical framework that seeks to grasp the empirical variety and complexity of delegative processes and appointed institutions. The framework is used to describe decision‐making processes and institutions in six countries: Austria, Germany, Norway, Sweden, New Zealand, and the United Kingdom. We find that, although constrained by preexisting institutional structures and traditions, delegators enjoy a considerable degree of discretion in their institutional design choices and engage in strategic design and redesign of appointed bodies.     

Validated method for the simultaneous determination of Delta9-THC and Delta9-THC-COOH in oral fluid, urine and whole blood using solid-phase extraction and liquid chromatography-mass spectrometry with electrospray ionization

A fully validated, sensitive and specific method for the extraction and quantification of Delta(9)-tetrahydrocannabinol (THC) and 11-nor-9-carboxy-Delta(9)-THC (THC-COOH) and for the detection of 11-hydroxy-Delta(9)-THC (11-OH THC) in oral fluid, urine and whole blood is presented. Solid-phase extraction and liquid chromatography-mass spectrometry (LC-MS) technique were used, with electrospray ionization. Three ions were monitored for THC and THC-COOH and two for 11-OH THC. The compounds were quantified by selected ion recording of m/z 315.31, 329.18 and 343.16 for THC, 11-OH THC and THC-COOH, respectively, and m/z 318.27 and 346.26 for the deuterated internal standards, THC-d(3) and THC-COOH-d(3), respectively. The method proved to be precise for THC and THC-COOH both in terms of intra-day and inter-day analysis, with intra-day coefficients of variation (CV) less than 6.3, 6.6 and 6.5% for THC in saliva, urine and blood, respectively, and 6.8 and 7.7% for THC-COOH in urine and blood, respectively. Day-to-day CVs were less than 3.5, 4.9 and 11.3% for THC in saliva, urine and blood, respectively, and 6.2 and 6.4% for THC-COOH in urine and blood, respectively. Limits of detection (LOD) were 2 ng/mL for THC in oral fluid and 0.5 ng/mL for THC and THC-COOH and 20 ng/mL for 11-OH THC, in urine and blood. Calibration curves showed a linear relationship for THC and THC-COOH in all samples (r(2)>0.999) within the range investigated. The procedure presented here has high specificity, selectivity and sensitivity. It can be regarded as an alternative method to GC-MS for the confirmation of positive immunoassay test results, and can be used as a suitable analytical tool for the quantification of THC and THC-COOH in oral fluid, urine and/or blood samples.
