Harmonizing the relationship between urbanization and eco-environment is not only an important proposition for the national development plan but also the only way to promote healthy urbanization. Based on an analysis of urbanization process and its relationship with the eco-environment, this article analyzes interactive coercing effects between urbanization and eco-environment from three perspectives of population urbanization, economic urbanization and spatial urbanization, respectively, and analyzes risk effects of the interactive coercion. Further, it shows six basic laws followed by interactive coercion between urbanization and eco-environment, namely, coupling fission law, dynamic hierarchy law, stochastic fluctuation law, non-linear synergetic law, threshold value law and forewarning law, and divides the interactive coercing process into five stages, namely, low-level coordinate, antagonistic, break-in, ameliorative and high-grade coordinate. Based on the geometric derivation, the interactive coercing relationship between urbanization and eco-environment is judged to be non-linear and it can be explained by a double-exponential function formed by the combination of power and exponential functions. Then, the evolutionary types of the interactive coercing relationship are divided into nine ones: rudimentary coordinating, ecology-dominated, synchronal coordinating, urbanization lagging, stepwise break-in, exorbitant urbanization, fragile ecology, rudimentary break-in and unsustainable types. Finally, based on an interactive coercion model, the degree of interactive coercion can be examined, and then, an evolutionary cycle can be divided into four phases, namely rudimentary symbiosis, harmonious development, utmost increasing and spiral type rising. The study results offer a scientific decision-making of healthy urbanization for achieving the goal of eco-environment protection and promoting urbanization.展开更多

In predominantly low- and middle-income countries, this contributes significantly to their risk for HIV infection, unwanted pregnancy, and sexually transmitted diseases. Current trends show that young people sexual identity and preferences affect their sexual and reproductive health. Objective: This study aims to determine prevalence of coerced or forced sexual intercourse, sexual identity and sexual preferences of young people in Oluku Community, Ovia North East, Local Government, Edo State, South Nigeria. Methods: A descriptive cross-sectional study conducted in June, 2013 using multi-stage sampling method. Results: A total of 400 young people participated in this study. The mean age was 17.8 ± 3.9 years. A higher proportion of respondents were of the Bini ethnic group 145 (36.3%). Most respondents were Christians 346 (86.5%) while 33 (8.2%) were Moslems. Majority of the respondents had secondary education 271 (67.8%), most were single 363 (90.8%) and were from families with a monogamous setting 289 (72.3%). The prevalence of forced sex was 12.9%, similarly, condom use during forced sex was 27.8%. More females (15.3%) than males (9.6%) had experienced forced sex;forced sex was common among young people from older age group, monogamous homes, and those living in a flat or self contained. Majority (95.3%) of adolescent’s sexual preference was vaginal, only a few preferred oral (3.3%) and anal sex (1.5%). Religion was associated with sexual preference and identity. The sexual identity of most (98.0%) young person’s was heterosexual (or different sex), while 0.5% were homosexual (or same sex) and 1.5% bisexual (or both). Conclusion and Recommendations: Legislation against forced and coerced sex, rape and other forms of sexual violence should be formulated and implemented.展开更多
