In many demographic behaviors (e.g., those relating to marriage, contraception, migration, and health), people change among multiple statuses through time, sometimes leaving and then returning to the same status. Data on such behaviors are often collected in surveys as censored event histories. The multistate life table (MSLT) can be used to properly describe, in a single analysis, these complex transitions among multiple states measured in such data, but MSLT is rarely applied in the demographic literature because practical guidance is lacking on how to compute MSLTs with such data. We provide methods for computing MSLT quantities using censored event-history data: namely, transition intensities and probabilities, "state occupancy" probabilities and standard errors, average time spent in specified states, and average number of visits to specified states. Applying these methods to contraceptive use, we find high levels of switching back and forth, particularly between barrier methods and non-use, resulting in high rates of unintended pregnancy.  相似文献

The COVID-19 pandemic created multiple stressors for college students, particularly for young adults experiencing multiple forms of disadvantage. Little is known about the pandemic experiences of independent college students, many of whom are emancipated minors, former wards of the state, and other students who lack familial financial and practical support as they pursue higher education. Twenty-three independent students, ages 18–23, from one northeastern university were interviewed to understand how independent students were affected by the COVID-19 pandemic, and their needs for support from the university during this time. Most participants were identified as Black or Latinx, and two thirds were first-generation college students. Participants reported an overall lack of support from their families prior to the pandemic. During the pandemic, they experienced compounding academic, economic, and mental health-related stressors. Students responded to these stressors in resilient and resourceful ways, by adapting to their new realities, expressing gratitude, and finding opportunities for self-growth. Participants recommend that institutions of higher education support independent students during periods of emergency through providing financial assistance, offering opportunities for connection with both adults and peers, and demonstrating administrative flexibility and understanding of their unique needs.  相似文献

We examine the issues concerning the legality and ethicality of the Second Amendment right to bear arms balanced by the employer's duty to provide a safe workplace for its employees. Two court rulings highlight this balancing act: McDonald et al. v. City of Chicago et al. and District of Columbia v. Heller. “Stand Your Ground” and “Castle Doctrine” laws in the recent Trayvon Martin shooting on February 26, 2012 are also applicable. Various ethical frameworks examine the firearms debate by viewing the Second Amendment from three perspectives. These include a pro‐gun perspective drawing upon libertarianism and fundamental rights; a moderate gun perspective drawing upon consequentialism and stakeholder theory; and finally, an anti‐gun perspective drawing upon a Public Health Ethics and peace ethics approach. We explore the issue of gun control from a business perspective as employers face ethical decisions in responding to legislation that allows guns in the workplace and/or in employer parking lots while still being responsible to provide a safe workplace for their employees. We make recommendations regarding how companies should manage by proactively avoiding legal challenges to employees' rights to own and carry guns into the workplace. This includes emphasis on enhanced security, Human Resource policies and monitoring rapidly changing laws.  相似文献
