Association of State Laws and Healthcare Workers' Influenza Vaccination Rates.

State laws are being used to increase healthcare worker (HCW) influenza vaccine uptake. Approximately 40% of states have enacted such laws but their effectiveness has been infrequently studied. Data sources for this study were the 2000-2011 U.

Hospital policies, state laws, and healthcare worker influenza vaccination rates.

This study used hierarchical linear modeling to determine the relative contribution of hospital policies and state laws to healthcare worker (HCW) influenza vaccination rates. Hospital mandates with consequences for noncompliance and race were associated with 3%-12% increases in HCW vaccination; state laws were not significantly related to vaccination rates.

School closure as an influenza mitigation strategy: how variations in legal authority and plan criteria can alter the impact.

Background: States' pandemic influenza plans and school closure statutes are intended to guide state and local officials, but most faced a great deal of uncertainty during the 2009 influenza H1N1 epidemic. Questions remained about whether, when, and for how long to close schools and about which agencies and officials had legal authority over school closures.

Methods: This study began with analysis of states' school-closure statutes and pandemic influenza plans to identify the variations among them.

Preparedness for pandemics: does variation among states affect the nation as a whole?

Objective: Since states' public health systems differ as to pandemic preparedness, this study explored whether such heterogeneity among states could affect the nation's overall influenza rate.

Design: The Centers for Disease Control and Prevention produced a uniform set of scores on a 100-point scale from its 2008 national evaluation of state preparedness to distribute materiel from the Strategic National Stockpile (SNS). This study used these SNS scores to represent each state's relative preparedness to distribute influenza vaccine in a timely manner and assumed that "optimal" vaccine distribution would reach at least 35% of the state's population within 4 weeks.

Species-specific SSR alleles for studies of hybrid cattails (Typha latifolia x T. angustifolia; Typhaceae) in North America.

Premise: Studies of hybridizing species are facilitated by the availability of species-specific molecular markers for identifying early- and later-generation hybrids. Cattails are a dominant feature of wetland communities, and a better understanding of the prevalence of hybrids is needed to assess the ecological and evolutionary effects of hybridization. Hybridization between Typha angustifolia and T.

State courts and public health: building partnerships to enhance preparedness.

Laws and regulations can facilitate or impede emergency preparedness and response activities. State legislators, judges, and lawyers play critically important roles in creating and interpreting laws that affect the ability of public health practitioners and their partners to effectively respond to emergencies. In an age when political unrest, global travel, and emerging biological threats can combine to create social and economic havoc worldwide, it is critical that those responsible for upholding the rule of law during emergencies understand the law and its implications.

When divergent life histories hybridize: insights into adaptive life-history traits in an annual weed.

*Colonizing weed populations face novel selective environments, which may drive rapid shifts in life history. These shifts may be amplified when colonists are hybrids of species with divergent life histories. Selection on such phenotypically diverse hybrids may create highly fecund weeds.

Rapid evolution in crop-weed hybrids under artificial selection for divergent life histories.

When species hybridize, offspring typically exhibit reduced fitness and maladapted phenotypes. This situation has biosafety implications regarding the unintended spread of novel transgenes, and risk assessments of crop-wild hybrids often assume that poorly adapted hybrid progeny will not evolve adaptive phenotypes. We explored the evolutionary potential of early generation hybrids using nontransgenic wild and cultivated radish (Raphanus raphanistrum, Raphanus sativus) as a model system.

Assessing bioterrorism and disaster preparedness training needs for school nurses.

Meeting the complex needs of a school system and all its members in the event of a bioterrorism (BT) disaster demands a competent workforce. School nurses are in position to be key contributors to planning for and responding to potential BT and disaster events. As part of a state preparedness leadership institute, the BT and disaster preparedness needs of school nurses in a three-county area were assessed and the nurses' preferred method to meet those needs was determined.
