An analysis of state crime: negotiating multiple insecurities around the U.S. Mexico Border

This research looks into forms of state crime taking place around the U.S.-Mexico border. On the Mexican side of the border violent corruption and criminal activities stemming from state actors complicity with drug trafficking organisations has produced widespread violence and human casualty while forcing many to cross the border legally or illegally in fear for their lives. Upon their arrival on the U.S. side of the border, these individuals are treated as criminal suspects. They are held in immigration detention facilities, interrogated and categorised as inadmissible ‘economic migrants’ or ‘drug offenders’ only to be denied asylum status and deported to dangerous and violent zones in Mexico. These individuals have been persecuted and victimised by the state during the 2007-2012 counter narcotic operations on one side of the border while criminalised and punished by a categorizing anti-immigration regime on the other side of the border. This thesis examines this border crisis as injurious actions against border residents have been executed by the states under legal and illegal formats in violation of criminal law and human rights conventions. The ethnographic research uses data to develop a nuanced understanding of individuals’ experiences of state victimisation on both sides of the border. In contributing to state crime scholarship it presents a multidimensional theoretical lens by using organised crime theoretical models and critical criminology concepts to explain the role of the state in producing multiple insecurities that exclude citizens and non-citizens through criminalisation processes.

Quantification of variable palmar ligaments around the triquetrum-hamate joint determined by lunate type

The ligaments of the wrist are highly variable and poorly described, which is more obvious on the ulnar side of the wrist. Previous studies highlighted the potential differences within the ligaments of the wrist but no consensus has been reached. Poor tissue description and inconsistent use of terminology hindered the reproducibility of the results. Improved understanding of the morphological variations between carpal bones may facilitate improved understanding of the ligamentous structure within the wrist. This study aims to identify the potential variations between carpal bones that could be used to separate palmar ligamentous patterns around the triquetrum-hamate joint into subgroups within the sample population. Investigations were performed following a detailed nomenclature and a clear definition of ligamentous structures to facilitate detailed description and reproducible results. Quantitative analyses were conducted using 3D modelling technique. Histological sections were then analysed to identify the structure of each ligamentous attachment. Variable patterns of ligamentous attachments were identified. Differences were not only obvious between samples but also between the right and left hands of the same person. These identifications suggested that the palmar ligamentous patterns around the triquetrum-hamate joint are best described as a spectrum with a higher affinity of the triquetrum-hamate-capitate ligament and the lunate-triquetrum ligament to be associated with type I lunate wrists on one extreme and type II lunate wrists with the palmar triquetrum-hamate ligament, triquetrum-hamate-capitate ligament and palmar radius-lunate-triquetrum ligament attachments at the other extreme. Histological analyses confirmed pervious established work regarding the mechanical role of ligaments in wrist joint biomechanics. Also, there were no significant differences between the quantitative data obtained from the Genelyn-embalmed and unembalmed specimens (p>0.05). The current study demonstrated variable ligamentous patterns that suggest different bone restraints and two different patterns of motion. These findings support previous suggestions regarding separating the midcarpal joint into two distinct functional types. Type I wrists were identified with ligamentous attachments that are suggestive of rotating/translating hamate whilst type II wrists identified with ligamentous attachments that are suggestive of flexing/extending hamate motion based upon the patterns of the ligamentous attachments in relation to the morphological features of the underlying lunate type of the wrist. This opens the horizon for particular consideration and/or modification of surgical procedures, which may enhance the clinical management of wrist dysfunction.
