Recent cyber attacks provide evidence of increased threats to our critical systems and infrastructure. A common reaction to a new threat is to harden the system by adding new rules and regulations. As federal and state governments request new procedures to follow, each of their organizations implements their own cyber defense strategies. This unintentionally increases time and effort that employees spend on training and policy implementation and decreases the time and latitude to perform critical job functions, thus raising overall levels of stress. People's performance under stress, coupled with an overabundance of information, results in even more vulnerabilities for adversaries to exploit. In this article, we embed a simple regulatory model that accounts for cybersecurity human factors and an organization's regulatory environment in a model of a corporate cyber network under attack. The resulting model demonstrates the effect of under‐ and overregulation on an organization's resilience with respect to insider threats. Currently, there is a tendency to use ad‐hoc approaches to account for human factors rather than to incorporate them into cyber resilience modeling. It is clear that using a systematic approach utilizing behavioral science, which already exists in cyber resilience assessment, would provide a more holistic view for decisionmakers. 相似文献

In 2006 and 2007, many analysts expected that immigration would be one of the top domestic issues in the 2008 campaign. However, in the 2008 presidential general election, immigration issues were never a major topic between candidates John McCain and Barack Obama. This was partially because McCain has more moderate views toward immigration reform than the passionate anti-immigration faction of the Republican Party. Prior research suggests that an issue in a presidential campaign can remain influential even when the media and campaigns are not discussing or addressing the issue, even when the candidates or parties do not differ greatly on the issue. In a survey of Virginia residents conducted just before the November election, immigration attitudes were a differential factor between McCain and Obama. 相似文献

We assess the relationship between skin color and educational attainment for native-born non-Hispanic Black and White men and women, using data from the Coronary Artery Risk Development in Young Adults (CARDIA) Study. CARDIA is a medical cohort study with twenty years of social background data and a continuous measure of skin color, recorded as the percent of light reflected off skin. For Black men and women, we find a one-standard-deviation increase in skin lightness to be associated with a quarter-year increase in educational attainment. For White women, we find an association approximately equal in magnitude to that found for Black respondents, and the pattern of significance across educational transitions suggests that skin color for White women is not simply a proxy for family background. For White men, any relationship between skin color and attainment is not robust and, analyses suggest, might primarily reflect differences in family background. Findings suggest that discrimination on the basis of skin color may be less specific to race than previously thought. 相似文献

The authors reviewed the conflict of interest policies of 9 academic medical centers in the United States and interviewed members of the Institutional Review Boards (IRBs) and Conflict of Interest Committees (COICs) at those institutions. They found that many institutions used processes for reporting and managing conflicts of interest that were more decentralized than the processes described in their policies. Also, most institutions had no clear and comprehensive policy to guide investigators regarding disclosure of conflicts of interest to potential research participants. Considerable differences in understanding of conflict of interest policies were observed between IRB and COIC officials. 相似文献

Population-based genetic research, including genetic epidemiology, shows tremendous potential to elucidate the role of genes as causal factors in complex and common human diseases. Like all research with human subjects, full realization of these benefits requires careful attention to its ethical conduct, establishing an appropriate balance between individual protections and the advancement of scientific and medical knowledge. This article reviews the growing literature on genetics research and ethics to describe some of the fundamental ethical issues in population-based genetics research, including research design, recruitment and informed consent, and dealing with research results. Its focus is on areas where consensus is forming and where future work is needed. 相似文献

HIV risks decline sharply at age 30 for women in South Africa, long before coital frequencies or pregnancies decrease. I evaluate
several prominent behavioral models of HIV, and find that these do not suggest sharply decreasing risks with age. I formulate
a model of spousal search and find that “marital shopping” can generate epidemic HIV prevalence despite low transmission rates
because search behavior interacts with dynamics of HIV infectiousness. The implied age-infection profile closely mimics that
in South Africa, and the suggested behavior matches that reported by South Africans. Condom use in new relationships and transmission
rate reductions are both found to be effective policies and, when used together, eliminate the potential of spousal search
to spread HIV. In contrast, antiretroviral treatment is found to have only a minimal effect on the epidemic. 相似文献

Social Networks and Support,Gender, and Racial/Ethnic Disparities in Hypertension Among Older Adults
Using data from the 2001 NHIS and the 2005–2006 and 2007–2008 NHANES, we examine how self-reporting a previous diagnosis of
hypertension among adults aged 65+ differs by race/ethnicity for men and women; we explore the extent to which disparities
are driven by group differences in social risk factors, particularly social support and integration; and last, whether these
relationships mimic patterns seen for measured hypertension at interview. Findings indicate that rates of ever-diagnosed hypertension
in both samples are highest among black seniors and older women and lowest among Mexican-American men, with the gender gap
lowest among whites and substantially higher among blacks and Mexican-Americans. However, replication analyses of NHANES models
using measured hypertension, instead of a self-report of having ever been diagnosed with hypertension, suggests that reporting
bias and measurement error contribute to observed disparities, as racial/ethnic differences in hypertension rates are smaller
when measured hypertension is examined, especially among women. Logistic regression models also show that while adjusting
for group differences in measures of support and integration mediates some of the disparity in measured hypertension between
Mexican-American and white seniors, adjusting for support and integration amplifies black-white disparities in both ever diagnosed
and measured hypertension—driven primarily by adjustment for attendance at religious services, which reduces hypertension
risk for all older adults but is more commonly reported among black seniors, especially women. 相似文献

More than a decade ago, scholars formally conceptualized the potential synergy between leadership and entrepreneurship scholarship. Our work highlights research accomplishments occurring at the interface of these two intellectual areas as well as identifying untapped possibilities for continued research. We highlight how recent efforts have witnessed a mutual exchange of ideas that present opportunities benefiting both fields. Drawing from four key domains of entrepreneurship previously proposed to mutually inform future leadership research efforts, we make suggestions for integrating entrepreneurial opportunities, the roles of individual and entrepreneurial teams, the modes of organizing entrepreneurial ventures, and differing entrepreneurial environments with key trends important to leadership research, such as servant leadership and leader-member exchange theory. Overall, our work provides an assessment of the state of the art surrounding the coalescence of leadership and entrepreneurship research and sets an agenda for the next decade of research at this intersection. 相似文献
