The Valuation Impact of Financial Advisors: An Empirical Analysis of REIT Mergers and Acquisitions
This paper analyzes the effect of financial advisor-monitors on the valuation of real estate investment trust (REIT) mergers. Advisor choice determinants and the effect of advisors on transaction value are examined using a sample of REIT mergers for the 1981 to 2001 period. A two-stage target firm pricing model is estimated: the first stage (logit) estimates the probability of advisor use and the second stage analyzes the effect of advisors on target firm valuation. The results indicate that financial advisor monitoring, possibly by reducing information asymmetries, has significant positive effects on the value of REIT acquisitions.
Banking Geography and Cross-Fertilization in the Productivity Growth of US Commercial Banks
The US banking industry offers a unique, natural and fertile environment to study geography's effects on banks' behavior and performance. The literature on banks' operating performance, while extensive, says little about the influence of spatial interactions on banks' performance. We compute and examine, using a physical distance-based spatio-temporal empirical model, the state-wide total factor productivity growth (TFPG) indices of US commercial banks for each state for the 1971-1995 period. We observe that the productivity growth of commercial banks in state i depends strongly, positively, and contemporaneously on the productivity growth of commercial banks located in state i's contiguous states. Further, âregulatory spaceâ appears to induce frictions and lessen the documented spatial interactions. These findings support our plea that research on commercial banking sector's behavior need to pay a particular attention to the effects of banking geography.Spatial, Commercial Banks, Total Factor Productivity Growth, Kalman Filter

A Commentary
17 USC 105 interim-entered record; under review.It is with great interest that we read the article on the twentyfirst-century hospital ship by the esteemed Rear Adm. (ret.) Michael Baker, Mr. Jacob Baker, and Capt. (ret.) Fred âSkipâ Burkle. Many of the concepts they outline are viable options worth consideration, but the future hospital ship is only one piece of the system-based, integrated approach for projecting medical power in support of Naval superiority.Identified in text as U.S. Government work
Patient- and population-level health consequences of discontinuing antiretroviral therapy in settings with inadequate HIV treatment availability
Background
In resource-limited settings, HIV budgets are flattening or decreasing. A policy of discontinuing antiretroviral therapy (ART) after HIV treatment failure was modeled to highlight trade-offs among competing policy goals of optimizing individual and population health outcomes. Methods
In settings with two available ART regimens, we assessed two strategies: (1) continue ART after second-line failure (Status Quo) and (2) discontinue ART after second-line failure (Alternative). A computer model simulated outcomes for a single cohort of newly detected, HIV-infected individuals. Projections were fed into a population-level model allowing multiple cohorts to compete for ART with constraints on treatment capacity. In the Alternative strategy, discontinuation of second-line ART occurred upon detection of antiretroviral failure, specified by WHO guidelines. Those discontinuing failed ART experienced an increased risk of AIDS-related mortality compared to those continuing ART. Results
At the population level, the Alternative strategy increased the mean number initiating ART annually by 1,100 individuals (+18.7%) to 6,980 compared to the Status Quo. More individuals initiating ART under the Alternative strategy increased total life-years by 15,000 (+2.8%) to 555,000, compared to the Status Quo. Although more individuals received treatment under the Alternative strategy, life expectancy for those treated decreased by 0.7 years (â8.0%) to 8.1 years compared to the Status Quo. In a cohort of treated patients only, 600 more individuals (+27.1%) died by 5 years under the Alternative strategy compared to the Status Quo. Results were sensitive to the timing of detection of ART failure, number of ART regimens, and treatment capacity. Although we believe the results robust in the short-term, this analysis reflects settings where HIV case detection occurs late in the disease course and treatment capacity and the incidence of newly detected patients are stable. Conclusions
In settings with inadequate HIV treatment availability, trade-offs emerge between maximizing outcomes for individual patients already on treatment and ensuring access to treatment for all people who may benefit. While individuals may derive some benefit from ART even after virologic failure, the aggregate public health benefit is maximized by providing effective therapy to the greatest number of people. These trade-offs should be explicit and transparent in antiretroviral policy decisions
The role of virtual photons in nanoscale photonics
The fundamental theory of processes and properties associated with nanoscale photonics should properly account for the quantum nature of both the matter and the radiation field. A familiar example is the Casimir force, whose significant role in nanoelectromechanical systems is widely recognised; the correct representation invokes the creation of short-lived virtual photons from the vacuum. In fact, there is an extensive range of nanophotonic interactions in which virtual photon exchange plays a vital role, mediating the coupling between particles. This review surveys recent theory and applications, also exhibiting novel insights into key electrodynamic mechanisms. Examples are numerous and include: laser-induced inter-particle forces known as optical binding; non-parametric frequency-conversion processes especially in rare-earth doped materials; light-harvesting polymer materials that involve electronic energy transfer between their constituent chromophores. An assessment of these and the latest prospective applications concludes with a view on future directions of research
Why do women not use antenatal services in low and middle income countries? A metasynthesis of qualitative studies
Background:
Almost 50% of women in low & middle income countries (LMICâs) donât receive adequate antenatal care. Womenâs views can offer important insights into this problem. Qualitative studies exploring inadequate use of antenatal services have been undertaken in a range of countries, but the findings are not easily transferable. We aimed to inform the development of future antenatal care programmes through a synthesis of findings in all relevant qualitative studies.
Methods and Findings:
Using a pre-determined search strategy, we identified robust qualitative studies reporting on the views and experiences of women in LMICâs who received inadequate antenatal care. We used meta-ethnographic techniques to generate themes and a line of argument synthesis. We derived policy relevant hypotheses from the findings.
We included 21 papers representing the views of more than 1230 women from 15 countries. Three key themes were identified: âPregnancy as socially risky and physiologically healthyâ; âResource use and survival in conditions of extreme povertyâand âNot getting it right first timeâ. The line of argument synthesis describes a dissonance between programme design and cultural contexts that may restrict access and discourage return visits. We hypothesize that centralized, risk-focused antenatal care programmes may be at odds with the resources, beliefs and experiences of pregnant women who underuse antenatal services.
Conclusions:
Our findings suggest that there may be a mis-alignment between current antenatal provision and the social and cultural context of some women in LMICâs. Antenatal care provision that is theoretically and contextually at odds with local contextual beliefs and experiences are likely to be underused, especially when attendance generates increased personal risks of lost family resource or physical danger during travel; when the promised care is not delivered due to resource constraints; and when women experience covert or overt abuse in care settings
