Invasive Alien Species and the Protection of Biodiversity: The Role of Quarantine Laws in Resolving Inadequacies in the International Legal Regime

There is growing awareness of the environmental problems causedby the introduction of invasive alien species, described bythe IUCN as one of the major threats to biological diversity.Despite difficulties in definition and identification, internationalregimes have increasingly attempted to tackle the issue, withover 40 treaties referring to the regulation of invasive species.But current international law is acknowledged to have severeshortcomings. Quarantine controls, though originally designedto protect human health and agricultural commerce, could playa critical role as a country’s first line of defence incontaining the spread of invasive alien species. The internationalquarantine regime is conceptually well placed to spearhead thefight against invasive alien species, but there are considerableproblems with the current structures. An analysis of how currentinternational trade law and in particular the 1994 Agreementon Sanitary and Phytosanitary Measures may conflict with internationaland national quarantine measures shows that the World TradeOrganization, in its enthusiasm to prevent quarantine laws beingused as a disguised restriction on trade, has discouraged membersfrom using such laws to stem the spread of invasive alien species.Much greater cooperation between the relevant parties will berequired to reverse this trend.     

Bite motivation of sharks reflected by the wound structure on humans

Bite wounds on humans have rarely been comparatively analyzed, and the behavior leading to such bites is virtually unknown. Nevertheless, the behavior of a shark is reflected in the bite structure and should be an essential part of shark-accident analysis. This paper compares 3 nonfatal accidents on humans, caused by bull sharks, Carcharhinus leucas, that occurred within a 12-month period in the same area of the Bahamas. Examination focused on wound analysis and accident reconstruction to determine the most likely bite motivation of the sharks. Two sharks targeted the left calf areas of the victims; another one bit the back area of a person. Although both calf bites had a very similar appearance, examination concluded that one of them showed the same triggering behavior as for the shark who inflicted the very different-looking back bite. Those 2 bites were competitive, whereas the other calf bite was initially of exploratory nature, turning into a stress-related bite.     

Methamphetamine in hair and interpretation of forensic findings in a fatal case

Hair analysis for drugs has been developing and is considered a significant tool for distinguishing between recent and long-term drug abuse in forensic and clinical toxicology. Chronic consumption of drugs can gradually induce certain harmful effects on the human organism and can exacerbate some pre-existing diseases. Analysis for drugs in blood or urine in isolation does not provide sufficient information about the history of drug-use by a person and their results cannot be correlated directly with the toxic effects displayed. The chronic abuse of methamphetamine is known to be associated with cardiovascular diseases. During or after autopsy certain types of morphologic alterations are found in the hearts of stimulant addicts. The rapid increase in blood pressure after an intravenous methamphetamine dose can be risky for addicts with arteriosclerosis. However, the anamnestic data about a deceased person may not always be available to explain the pathological findings and to classify the cause of death correctly. The aim of this study was to demonstrate the value of hair analysis for drugs in the context of explaining pathological cardiovascular alterations observed during the autopsy in a case where methamphetamine consumption was involved. In this case, only methamphetamine and metabolites were detected with traces of ephedrine. Ephedrine is the precursor chemical in the illicit synthesis of methamphetamine (known in the Czech Republic as "Pervitin"). The femoral blood level of methamphetamine was 1500 ng/ml. It was documented by a witness that the 31-year-old man died within 1h after an intravenous injection of the drug. The cause of death was established as cerebral edema due to cerebellar bleeding shortly after an intravenous dose of methamphetamine. Findings of methamphetamine in the first three 2-cm hair segments (numbered from the roots) were nearly equal (132+/-9 ng/mg). In the fourth 2-cm segment, it was approximately one-half of previous values. In the remaining, distal 7-cm hair segment sample, the value of methamphetamine was higher and comparable to the third segment. These results provide clear evidence that the man had been a chronic methamphetamine abuser for more than 8 months. This information can help to explain the pathology, the consequence of which could be the bleeding into the cerebellum after the last single methamphetamine dose.     

We've had training, now what? Qualitative analysis of barriers to domestic violence screening and referral in a health care setting

The present study assesses barriers to identification and referral of domestic violence (DV) victims by staff at a health care institution following a 3-hr DV training program in which 752 health care providers participated. Focus groups are conducted with staff in hospital departments that serve a high volume of women. Responses to focus group questions identify system-wide and individual hospital department barriers. These barriers have implications for health care organizations trying to implement DV screening protocols through training alone to change staff behavior in diverse clinical settings. Limitations of this study and future research recommendations are also discussed.     

The Impact of Immigration on the Internal Processes and Developmental Tasks of Emerging Adulthood

This study examines the experience of emerging adult immigrants, a group simultaneously attempting to navigate the developmental period of exploration and experimentation of emerging adulthood, together with the need for re-organization of the self, following immigration. In this study, in-depth interviews were conducted, with 41 emerging adult immigrants from the former Soviet Union in Israel and 42 non-immigrant Israeli emerging adults (all in the age group 21–25), on the subjects of sense of self, family relations, and age-appropriate tasks of emerging adulthood. Results showed that while immigrant emerging adults had a more disorganized sense of self, they also showed higher levels of both autonomy and relatedness in the relationship with their parents. Immigrant emerging adults had fewer social networks, yet more intimate relationships. Emerging adult immigrants' story was one of “relatedness” where level of self-organization was related to closeness, caring, and identification with parents, and closeness in both social and intimate relationships. In contrast, the non-immigrant emerging adults told about a process of “autonomy seeking” where a consolidated sense of self was related to more independent decision-making, emotional independence, and assertiveness in the relationship with parents. The findings of this study point to the complex and unique process that emerging adult immigrants undergo while coping with developmental tasks in their new environment.

The Role of Spirituality Versus Religiosity in Adolescent Psychosocial Adjustment

This study investigated the interaction between religiosity (defined as church attendance) and spirituality (defined as personal beliefs in God or a higher power) on psychosocial adjustment. Four groups were created capturing 4 different religious/spiritual orientations. Differences were assessed between the groups on a wide range of psychosocial indicators. Participants included 6578 adolescents ages 13–18 encompassing a school district in Ontario, Canada. Results were striking with regards to the consistency with which religious youth reported more positive adjustment than did non-religious youth, regardless of level of spirituality. Spirituality may not be as salient an influence on behavior as religiosity. The secondary analyses indicated that the advantage for religiosity may not be entirely unique to church attendance, but rather a function of being part of any community. However, where religiosity may be uniquely associated with adjustment (over and above benefits associated with participation in any community) is in lower levels of risk behaviors.

Supervisory responsibilities of specialists

The public hospital system in New Zealand is heavily reliant on junior doctors for the day-to-day provision of medical care to hospital patients. Specialists have supervisory responsibilities for junior doctors during the day, as leaders of clinical teams, and after hours when they are on call. Due to changes in the health system over the past 20 years, there has been a change in the nature and level of specialist supervision required. Under the Code of Health and Disability Services Consumers' Rights, where aspects of clinical care are delegated to junior doctors, specialists have a duty to provide supervision with reasonable care and skill and in accordance with professional standards.
