PLOS ONE , 2014, DOI: 10.1371/journal.pone.0094407
Abstract: White sharks are highly migratory apex predators, globally distributed in temperate, sub-tropical, and tropical waters. Knowledge of white shark biology and ecology has increased recently based on research at known aggregation sites in the Indian, Atlantic, and Northeast Pacific Oceans; however, few data are available for the Northwest Pacific Ocean. This study provides a meta-analysis of 240 observations of white sharks from the Northwest Pacific Ocean between 1951 and 2012. Records comprise reports of bycatch in commercial fisheries, media accounts, personal communications, and documentation of shark-human interactions from Russia (n = 8), Republic of Korea (22), Japan (129), China (32), Taiwan (45), Philippines (1) and Vietnam (3). Observations occurred in all months, excluding October-January in the north (Russia and Republic of Korea) and July-August in the south (China, Taiwan, Philippines, and Vietnam). Population trend analysis indicated that the relative abundance of white sharks in the region has remained relatively stable, but parameterization of a 75% increase in observer effort found evidence of a minor decline since 2002. Reliably measured sharks ranged from 126–602 cm total length (TL) and 16–2530 kg total weight. The largest shark in this study (602 cm TL) represents the largest measured shark on record worldwide. For all countries combined the sex ratio was non-significantly biased towards females (1:1.1; n = 113). Of 60 females examined, 11 were confirmed pregnant ranging from the beginning stages of pregnancy (egg cases) to near term (140 cm TL embryos). On average, 6.0±2.2 embryos were found per litter (maximum of 10) and gestation period was estimated to be 20 months. These observations confirm that white sharks are present in the Northwest Pacific Ocean year-round. While acknowledging the difficulties of studying little known populations of a naturally low abundance species, these results highlight the need for dedicated research to inform regional conservation and management planning.
A Re-Evaluation of the Size of the White Shark (Carcharodon carcharias) Population off California, USA

Abstract: White sharks are highly migratory and segregate by sex, age and size. Unlike marine mammals, they neither surface to breathe nor frequent haul-out sites, hindering generation of abundance data required to estimate population size. A recent tag-recapture study used photographic identifications of white sharks at two aggregation sites to estimate abundance in “central California” at 219 mature and sub-adult individuals. They concluded this represented approximately one-half of the total abundance of mature and sub-adult sharks in the entire eastern North Pacific Ocean (ENP). This low estimate generated great concern within the conservation community, prompting petitions for governmental endangered species designations. We critically examine that study and find violations of model assumptions that, when considered in total, lead to population underestimates. We also use a Bayesian mixture model to demonstrate that the inclusion of transient sharks, characteristic of white shark aggregation sites, would substantially increase abundance estimates for the adults and sub-adults in the surveyed sub-population. Using a dataset obtained from the same sampling locations and widely accepted demographic methodology, our analysis indicates a minimum all-life stages population size of >2000 individuals in the California subpopulation is required to account for the number and size range of individual sharks observed at the two sampled sites. Even accounting for methodological and conceptual biases, an extrapolation of these data to estimate the white shark population size throughout the ENP is inappropriate. The true ENP white shark population size is likely several-fold greater as both our study and the original published estimate exclude non-aggregating sharks and those that independently aggregate at other important ENP sites. Accurately estimating the central California and ENP white shark population size requires methodologies that account for biases introduced by sampling a limited number of sites and that account for all life history stages across the species' range of habitats.
Sever’s Disease: An Underdiagnosed Foot Injury in the Pediatric Emergency Department  [PDF]
Michael Marchick, Henry Young, Mathew F. Ryan
Open Journal of Emergency Medicine (OJEM) , 2015, DOI: 10.4236/ojem.2015.34007
Abstract: Sever’s disease—also known as calcaneal apophysitis—is a common cause of heel pain in pediatric patients typically aged 7 - 14 years old. Sever’s disease can be painful and limit a child’s function as well as participation in physical activity. Herein, we described a case of delayed presentation of chronic Sever’s disease in a child who had been experiencing heel pain for over one year which worsened substantially when the child began to participate in sports. This is important for the emergency medicine physician because Sever’s disease represents an underdiagnosed cause of foot and heel pain in the pediatric patient and may be often missed. We describe the diagnosis and treatment options of Sever’s disease as well as associated controversies, e.g., whether activity is indeed the cause of Sever’s disease and whether imaging is needed for a diagnosis.
Irradiation effects on meat: a review
Henry,Fábio Costa;
Revista de Ciências Agrárias , 2009,
Abstract: food irradiation is a process exposing food to ionizing radiations such as gamma rays emitted from the radioisotopes 60co and 137cs, or, high energy electrons and x-rays produced by machine sources. irradiation can induce formation of isooctane-soluble carbonyl compounds in the lipid fraction and acid-soluble carbonyls in the protein fraction of meat. increasing irradiation dose increases these compounds however, cooking reduces them. among the volatile components, 1-heptene and 1-nonene are influenced most by irradiation dose, and aldehydes (propanal, pentanal, hexanal) are influenced most by packaging type (aerobiose vs vacuum). sulfur-containing volatiles formed from sulfur-containing compounds (primarily amino acids) also contribute to irradiation odor. reducing the temperature during the irradiation process reduces the effects on odor/flavor because free radical generation and dispersion are reduced. ultimately, radiolysis of water into free radical species may be the initiators of both lipid oxidation breakdown products and sulfur-containing volatiles responsible for irradiation odor. methods to decrease the detrimental effects of irradiation include oxygen exclusion (vacuum packaging), replacement with inert gases (nitrogen) and addition of protective agents (antioxidants).

Health (Health) , 2013, DOI: 10.4236/health.2013.56131
Abstract:

Background and purpose: The rising cost of health care is of concern worldwide, in particular, for cancer care. The costs of treatment, including chemotherapeutic drugs and radiotherapy, are no exceptions. The purpose of this study is to explore the direct medical cost of radiotherapy and the annual increasing trend of expenditures in Taiwan. Methods: This study utilized data retrieving from the original claim data of the reimbursement of the Health Insurance Research Database (HIRD) derived from Taiwan’s Health Insurance (HI) program. Detailed data on the direct medical cost within the radiotherapy process for beneficences were extracted from inpatient expenditures by admissions (DD) and ambulatory care expenditures by visits (CD) database according to the reimbursed expenditure code of radiotherapy from January 1, 2000 to December 31, 2005. Prescriptions for radiotherapy were retrieved and the direct medical costs for radiotherapy were collected based on the NHI reimbursement price list of 2005. The annual increasing trend of expenditures was also explored according to the perspective of Bureau Health Insurance of Taiwan. Results: The total direct medical costs of radiotherapy for cancer patients were increasing from 2000 to 2005, which were estimated to US $7.80 million, US $8.09 million, US $7.58 million, US $10.7 million, US $12.2 million and US $15.9 million in 2000, 2001, 2002, 2003, 2004 and 2005, respectively. The increased percentage corresponded to the total healthcare expenditures claimed was increased substantially from 0.82% in 2000 to 1.22% in 2005. The total direct medical costs within the radiotherapy process were also increased gradually if identified by different types of radiotherapy and teaching hospital levels. The direct medical costs attribute to radiotherapy, compared to total health care expenditures in Taiwan, were similar to the costs of anticancer drugs for cancer patients annually. Conclusions: The direct medical costs of radiation therapy increased substantially each year. Further cost analysis on

Accounting as an Instrument of Social Justice  [PDF]
Theresa F. Henry, Athar Murtuza, Renee E. Weiss
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.31009
Abstract: This article builds upon calls for a shift in the paradigm of the accounting discipline, away from preparing or certifying financial reporting of management activities aimed at maximizing share-holder wealth toward recognition that businesses must also be accountable to other stakeholders and indeed the community at large. If individuals in business apply a sound moral compass to their activities and decisions, we believe that commerce can shift toward outcomes that may not only satisfy shareholders but also contribute to the common good. In this article, we are concerned with the role of accounting and business education. We enumerate recommendations toward achieving this paradigm shift from profit maximization to social justice. In some cases, the instructor may implement changes in their pedagogy at their discretion, while in other cases the change may require approval at the department or at higher levels of the university administration. We begin with a discussion of recent accounting and financial reporting failures as well as the global financial crisis. The dangers created by risky practices of financial institutions “too big to fail” and the systemic risk of a global marketplace have not been resolved. We articulate the need for ethics in the accounting and business curricula, a need that is hardly satisfied by the one course typically offered by universities at the graduate level. We propose that businesses and the accounting profession can realize change by redefining accounting as an instrument of accountability. To accomplish this change, each university must critically examine its curricula and reflect topics and material most important to ethical and moral behavior, including borrowing from the liberal arts disciplines. Finally, this article shows how an interfaith approach grounded in social justice to infuse ethical and moral behavior within the accounting curriculum can work.
Bilateral Pneumonia and Pleural Effusions Subsequent to Electronic Cigarette Use  [PDF]
Kendall Moore, Henry Young II, Matthew F. Ryan
Open Journal of Emergency Medicine (OJEM) , 2015, DOI: 10.4236/ojem.2015.33004
Abstract: Electronic nicotine delivery systems also known as electronic cigarettes (or e-cigarettes) are marketed by their manufactures as a safer alternative to tobacco cigarettes because of potentially reduced delivery of toxins. However, the scientific evidence and the long-term health effects of e-cigarettes are limited. We describe a case of a 43-year-old man who had been smoking electronic cigarettes excessively for three days and presented with acute dyspnea, increased work of breathing and tachycardia. Subsequent chest x-ray revealed bilateral pleural effusions. In addition, the patient had a new oxygen requirement and was thus admitted with a diagnosis of pneumonia and bilateral pleural effusions. The case and the potential harmful effects of electronic cigarettes are discussed herein.
Arthritic Hand-Finger Movement Similarity Measurements: Tolerance Near Set Approach
Christopher Henry,James F. Peters
Computational and Mathematical Methods in Medicine , 2011, DOI: 10.1155/2011/569898
Abstract: The problem considered in this paper is how to measure the degree of resemblance between nonarthritic and arthritic hand movements during rehabilitation exercise. The solution to this problem stems from recent work on a tolerance space view of digital images and the introduction of image resemblance measures. The motivation for this work is both to quantify and to visualize differences between hand-finger movements in an effort to provide clinicians and physicians with indications of the efficacy of the prescribed rehabilitation exercise. The more recent introduction of tolerance near sets has led to a useful approach for measuring the similarity of sets of objects and their application to the problem of classifying image sequences extracted from videos showing finger-hand movement during rehabilitation exercise. The approach to measuring the resemblance between hand movement images introduced in this paper is based on an application of the well-known Hausdorff distance measure and a tolerance nearness measure. The contribution of this paper is an approach to measuring as well as visualizing the degree of separation between images in arthritic and nonarthritic hand-finger motion videos captured during rehabilitation exercise.
