The concept of dependency, Platt asserts, is “scarcely sustainable” because its historical foundation is unconvincing. “Students of chrono-politics (history),” he implies, find unacceptable the notion that “development and expansion” of Western Europe's economy dominated and conditioned that of Latin America since the conquest. The fact that Dos Santos' definition of dependency denies the presence of autonomous development in Latin America is “critical.” Economic autonomy, according to Platt, is the leitmotif of Latin America's evolution, certainly to the close of the nineteenth century, when there “finally awoke metropolitan interest in the neglected periphery.”

Clinical and empirical reports suggest that individuals use non-suicidal self-injury (NSSI) not only to ameliorate dysphoria, but to curb suicidal ideation or avoid suicidal behaviour. To date, however, no study has quantitatively assessed whether NSSI leads to short-term reductions in suicidal ideation. Using real-time monitoring over 7 days in a sample with borderline personality disorder, we found evidence that NSSI is followed by reductions in suicidal ideation in the subsequent hours. This suggests that NSSI may serve as an effective, albeit maladaptive, coping strategy for suicidal states. These findings have important implications for the management of suicide risk and self-harm.

The cognitive profile of early onset Parkinson’s disease (EOPD) has not been clearly defined. Mutations in the parkin gene are the most common genetic risk factor for EOPD and may offer information about the neuropsychological pattern of performance in both symptomatic and asymptomatic mutation carriers. EOPD probands and their first-degree relatives who did not have Parkinson’s disease (PD) were genotyped for mutations in the parkin gene and administered a comprehensive neuropsychological battery. Performance was compared between EOPD probands with (N = 43) and without (N = 52) parkin mutations. The same neuropsychological battery was administered to 217 first-degree relatives to assess neuropsychological function in individuals who carry parkin mutations but do not have PD. No significant differences in neuropsychological test performance were found between parkin carrier and noncarrier probands. Performance also did not differ between EOPD noncarriers and carrier subgroups (i.e., heterozygotes, compound heterozygotes/homozygotes). Similarly, no differences were found among unaffected family members across genotypes. Mean neuropsychological test performance was within normal range in all probands and relatives. Carriers of parkin mutations, whether or not they have PD, do not perform differently on neuropsychological measures as compared to noncarriers. The cognitive functioning of parkin carriers over time warrants further study. (JINS, 2011, 17, 1–10)
