Auditor liability and excess cash holdings: Evidence from audit fees of foreign incorporated firms

Auditors of foreign cross-listed firms face liability arising from the nature of the institutional monitoring framework of legal claims that can potentially be brought against the auditor in both the home country and the US. This paper is the first to document the relationship between auditor liability and auditor pricing of excess cash holdings for foreign firms cross-listed in the US. Our findings indicate that auditors demand a fee premium for foreign incorporated clients with greater excess cash holdings, consistent with auditors recognizing the potential for legal exposure to agency conflict arising from foreign listed US traded clients. Furthermore, we examine aspects of foreign capital market protections, such as disclosure requirements, the strength of legal enforcement, and the strength of shareholder rights to better understand auditor perception of the liability they incur due to the agency costs associated with excess cash holdings. We find that there is a significant positive association between audit fees and excess cash holdings for firms where the country of incorporation permits greater liability of auditors in criminal and civil litigation. In addition, auditors assign higher audit fees to firms holding greater excess cash incorporated in countries with greater required accounting disclosure, stronger legal enforcement and stronger shareholder rights

Cargo of Birds to Arkansas, the Hurricanes in 2008 and the Swept Clean Hypothesis

Three hurricanes in the hurricane season of 2008 brought to Arkansas several unusual marine and other birds from southerly locations. There were 10 species noted, totaling 44 individual birds. Sooty Terns, numbering 15, were the most numerous. Laughing Gulls were next in abundance. In the mix of birds there was only 1 new species for the state, a Least Grebe. The hurricanes brought vastly different cargos of birds, and two hypotheses relating to how hurricanes transport birds are proposed. The findings supported the swept clean hypothesis over the blown through hypothesis

Increasing Teachers\u27 Metacognition Develops Students\u27 Higher Learning during Content Area Literacy Instruction: Findings from the Read-Write Cycle Project

Success in the 21st century, for individuals and societies, requires competence in comprehending and communicating in the academic disciplines--the natural sciences, history, geography, and more. The Read-Write Cycle (RWC) Project, a three year longitudinal research study conducted from 2005-2008 in ten public elementary schools in southern California, explored the effectiveness of curriculum and instructional strategies that integrate literacy with disciplinary knowledge with the simultaneous goals of: (1) enhancing students\u27 literacy outcomes; and (2) broadening and deepening knowledge of the content area. Funded by the U.S. Institute of Education Sciences, the RWC Project concentrated over years one and two on 1,024 students in grades three through six and the ongoing professional development of 18 classroom teachers. This documentary account focuses on one aspect of the larger project, specifically the RWC Project\u27s effect on teachers\u27 metacognition about their own practice leading to upper elementary grade students\u27 higher learning by developing students\u27: (1) metacognition and reflection; (2) exploration and depth in content domains; and (3) integration of literacy in content areas

HIV-free survival and morbidity among formula-fed infants in a prevention of mother-to-child transmission of HIV program in rural Haiti

<p>Abstract</p> <p>Background</p> <p>Partners In Health (PIH) works with the Ministry of Health to provide comprehensive health services in Haiti. Between 1994 and 2009, PIH recommended exclusive formula feeding in the prevention of mother-to-child transmission (PMTCT) of HIV program and provided support to implement this strategy. We conducted this study to assess HIV-free survival and prevalence of diarrhea and malnutrition among infants in our PMTCT program in rural Haiti where exclusive formula feeding was supported.</p> <p>Methods</p> <p>We reviewed medical charts of PMTCT mother-infant pairs at PIH between November 2004 and August 2006 through a retrospective longitudinal study and cross-sectional survey. We performed household surveys for each pair and at control households matched by infant's age and gender.</p> <p>Results</p> <p>254 mother-infant pairs were included. 15.3% of infants were low birth weight; most births occurred at home (68.8%). 55.9% of households had no latrine; food insecurity was high (mean score of 18; scale 0-27, SD = 5.3). HIV-free survival at 18 months was 90.6%. Within the cohort, 9 children (3.5%) were HIV-infected and 17 (6.7%) died. Community controls were more likely to be breastfed (P = 0.003) and more likely to introduce food early (P = 0.003) than PMTCT-program households. There was no difference in moderate malnutrition (Z score ≤ 2 SD) between PMTCT and community groups after controlling for guardian's education, marital status, and food insecurity (OR = 1.05; 95% CI: 0.67, 1.64; P = 0.84). Diarrhea was 2.9 times more prevalent among community children than PMTCT infants (30.3% vs. 12.2%; P < 0.0001).</p> <p>Conclusions</p> <p>In a PIH-supported program in rural Haiti that addressed socioeconomic barriers to ill-health, breast milk substitution was safe, acceptable and feasible for PMTCT for HIV-infected women choosing this option.</p

Reactive Attachment Disorder: Challenges for Early Identification and Intervention within the Schools

Attachment is of key importance in childhood development. The quality of attachment relationship between the child and parent/primary caregiver may have an effect on the child and future relationships and social success (Rubin, Bukowski, & Parker, 1998). When a child fails to bond with a caring adult, attachment becomes disordered and children may not be able to bond appropriately or at all with other people. This inability to relate and connect with others may disrupt or arrest not only children\u27s social development, but also their overall development. The purpose of this review is to synthesize information and research on characteristics, diagnosis, and interventions currently in practice in working with young children with Reactive Attachment Disorder (RAD). A discussion will highlight the themes found during this review and conclude with implications for intervention and practice
