Abstract Based on the conceptualizations of organized crime as both an enterprise and a form of governance, borderland as a spatial category, and borders as institutions, this paper looks at the politics of bordering practices by organized crime in the Colombian-Venezuelan borderlands. It posits that contrary to the common assumptions about transnational organized crime, criminal organizations not only blur or erode the border but rather enforce it to their own benefit. In doing so, these groups set norms to regulate socio-spatial practices, informal and illegal economies, and migration flows, creating overlapping social orders and, lastly, (re)shaping the borderland. Theoretically, the analysis brings together insights from political geography, border studies, and organized crime literature, while empirically, it draws on direct observation, criminal justice data, and in-depth interviews.

Tourists from abroad are increasing rapidly in Japan. Particular aims of local government are to overcome the common problems of an aging population and declining birthrate through tourism-generated income and to stimulate the local society through regional exchange and migration. In order to analyze economic aspects of tourism, accurate and up-to-date statistics and information regarding tourism are needed. Specifically, this study presents opportunities for inter-regional cooperation in marketing, in light of studies of tourist behavior at events featuring seasonal flowers and held in Kawazu town, which is located on the Izu Peninsula in Shizuoka Prefecture. In this paper, a questionnaire investigation is executed in order to clarify tourists’ behavior, and to seek the possibility of developing regional collaboration among local government, tourism related industry and visitors. Hypothesis testing was executed based on that. Some interesting and instructive results were obtained.

Regulatory Challenges

While vulnerability and migration are boundary concepts, they have been employed as if they were somewhat neutral and univocal. Based on the umbrella theory of the vulnerability turn, the specialist doctrine has focused its critical analyses on the legal-political dimensions of the different vulnerable subjects and groups. However, migrant vulnerability has a unique impact on the regulatory field of asylum, especially given its ambiguity and lack of legislative harmonisation across EU Member States. A review of the mechanisms for identifying and protecting migrant vulnerability can provide regulatory evidence regarding the different phases of the Common European Asylum System, which in turn can lead to proposals for its reform. This study will analyse the complex and questionable use of the category of ‘vulnerable migrant’ in the main international instruments of legal protection when applied to asylum seekers. It will then present a critical comparative analysis of the national and EU asylum framework.

And Migration

To obtain an image of the earth’s subsurface, time-imaging methods can be applied because they are reasonably fast, are less sensitive to velocity model errors than depth-imaging methods, and are usually easy to parallelize. A powerful tool for time imaging consists of a series of prestack time migrations and demigrations. We have applied multiparameter stacking techniques to obtain an initial time-migration velocity model. The velocity model building proposed here is based on the kinematic wavefield attributes of the common-reflection surface (CRS) method. A subsequent refinement of the velocities uses a coherence filter that is based on a predetermined threshold, followed by an interpolation and smoothing. Then, we perform a migration deconvolution to obtain the final time-migrated image. The migration deconvolution consists of one iteration of least-squares migration with an estimated Hessian. We estimate the Hessian by nonstationary matching filters, i.e., in a data-driven fashion. The model building uses the framework of the CRS, and the migration deconvolution is fully automated. Therefore, minimal user interaction is required to carry out the velocity model refinement and the image update. We apply the velocity refinement and migration deconvolution approaches to complex synthetic and field data.

Glioma is the common highly malignant primary brain tumor. However, the molecular pathways that result in the pathogenesis of glioma remain elusive. In this study, we found that microRNA-103 (miR-103), microRNA-195 (miR-195), or microRNA-15b (miR-15b), which all have the same 5′ “seed” miRNA portion and share common binding sites in the SALL4 3′-untranslated region (UTR), were downregulated in glioma tissues and cell lines. These miRNAs suppressed glioma cell proliferation, migration, and invasion, induced cell apoptosis, and decreased the level of the SALL4 protein, but not that of SALL4 mRNA, which was identified as a direct target of all three miRNAs. The caspase-3/7 activity expression in U251 cells overexpressing these miRNAs was rescued during SALL4 upregulation. An obvious inverse correlation was observed between SALL4 and miR-103 or miR-195 expression levels in clinical glioma samples. Moreover, enforced expression of SALL4 stimulated cell proliferation, migration, and invasion. In conclusion, these data suggest that miR-103, miR-195, and miR-15b post-transcriptionally downregulated the expression of SALL4 and suppressed glioma cell growth, migration, and invasion, and increased cell apoptosis. These results provide a potential therapeutic target that may downregulate SALL4 in glioma.

Extramarital pregnancy and illegitimate childbearing have been interpreted by historians as well as sociologists basically in terms of deviant behavior and lack of social control (Tranter 1985; Blaikie 1995). While society has looked at procreation outside marriage as a moral lapse, social science has regarded it in terms of deviancy, as “something which interrupted the proper functioning of social processes, and revealed a failure of social control, the control of individual behavior by family and kin, by political and educational authority” (Laslett 1980a: 1–2).Within this framework, interpretations of the “illegitimacy explosion” of the late eighteenth and early nineteenth centuries have almost invariably referred toweakening social control as a result of industrialization, urbanization, and migration. In the 1970s, the debate on the rise of illegitimacy was centered on Edward Shorter's contention that women's emancipation produced rising extramarital sexual activity. This article does not reopen that dispute (see Shorter 1971, 1975: 255–68; Tilly et al. 1976; Lee 1977; Fairchilds 1978; Alter 1988). Rather, it starts from the common ground underlying the different interpretations, which associates adolescent extramarital pregnancy with social isolation. Scholars have argued that migration and new living and working conditions often led to separation from the family and local community. This change would have resulted in the collapse of traditional social control, making premarital intercourse more likely.

ABSTRACTThe fertility, mortality, and migration patterns of Heterakis gallinarum were studied in chickens with concomitant Parahistomonas wenrichi infections. H. gallinarum females were found to produce approximately 936 ova per day, when 50 days of age, and a total of 34,000 to 86,000 ova in a lifetime. There was no evidence of differential mortality between the sexes, nor of a preference for either the left or the right caecal organ of chickens. Both male and female worms are capable of migrating between caeca, and are especially prone to do so when in the absence of individuals of the opposite sex.
