Recoil Effects Ensuing from 59Co (n, γ) 60Co and 59Co (γ, n) 58Co Reactions in Open Type Cobalt Complexes-II
Authors: Shankar J. , Nath Amar , Rao Μ. H. 
Published: June 2015

Summary
The 'open-type' cobalt complexes are characterized by a small (or zero) magnitude of post-recoil thermal annealing, both for (n, γ)and (γ, n)reactions. In this category of complexes, the stereochemical configurations do not permit efficient interaction with the energetic recoil atom and the excess energy is not dissipated rapidly enough, resulting in collapse of the molecule, and annealable metastable centres are not formed. Vitamin B12, though a hexacoordinated complex, belongs to this category by behaviour, while cobalt tetraphenylporphinate behaves differently.
Occluded oxygen decreases the magnitude of thermal anneal by virtue of its being an electron trap, thereby removing the electrons from the sphere of reaction.

Published: June 2015

Summary
A simple procedure is described for the preparation of pure 228Ac (MsTh2) from 228Ra(MsTh1). After initial purification of 228Ra from 228Th, the sample is left for a month 228Ra for and its daughters to decay completely. After this period, the Separation of 228Ac is straightforward. Using Dowex 50X8 resin and dilute nitric acid as eluting Solution, 228Ac is obtained in high specific activity and in carrier free form in a reasonably Short time. Rapid milking of 228Ac can be achieved daily by the use of 0,5 M ammonium-glycolic or an ammonium-α-hydroxyisobutyric solutions of p
H about 4.

Authors: Lange J. , Münzel H. 
Published: June 2015

Zusammenfassung
Die Anregungsfunktionen der (d, p)-, (d, 2n)- und (d, 3n)-Reaktionen für das Targetnuklid 141Pr und Projektilenergien bis maximal 50 MeV wurden bestimmt. Zur Deuteronenflußmessung diente ein selten angewandtes Monitorverfahren, bei dem statt der in uniformen Schichten angeordneten Target- und Monitorsubstanzen homogene Mischungen beider verwendet wurden. Für Deuteronenenergien, die unterhalb des Anwendungsbereiches der verwendeten 27Al(d, αp)24Na-Monitorreaktion lagen, wurden (d, 2n): (d, p)-Wirkungsquerschnittverhältnisse gemessen. Unter Verwendung der Anregungsfunktionen wurden die Ausbeuten für die Bestrahlung dicker Targets berechnet.
Von den Reaktionsprodukten wurden folgende Halbwertszeiten bestimmt: 140Nd 3,37 ± 0,02 d; 141Nd 2,60 ± 0,12 h; 142Pr 19,09 ± 0,07 h.
Stable Patterns of CENH3 Occupancy Through Maize Lineages Containing Genetically Similar Centromeres
Authors: Gent Jonathan I , Wang Kai , Jiang Jiming , Dawe R Kelly 
Published: June 2015

AbstractWhile the approximate chromosomal position of centromeres has been identified in many species, little is known about the dynamics and diversity of centromere positions within species. Multiple lines of evidence indicate that DNA sequence has little or no impact in specifying centromeres in maize and in most multicellular organisms. Given that epigenetically defined boundaries are expected to be dynamic, we hypothesized that centromere positions would change rapidly over time, which would result in a diversity of centromere positions in isolated populations. To test this hypothesis, we used CENP-A/cenH3 (CENH3 in maize) chromatin immunoprecipitation to define centromeres in breeding pedigrees that included the B73 inbred as a common parent. While we found a diversity of CENH3 profiles for centromeres with divergent sequences that were not inherited from B73, the CENH3 profiles from centromeres that were inherited from B73 were indistinguishable from each other. We propose that specific genetic elements in centromeric regions favor or inhibit CENH3 accumulation, leading to reproducible patterns of CENH3 occupancy. These data also indicate that dramatic shifts in centromere position normally originate from accumulated or large-scale genetic changes rather than from epigenetic positional drift.

ABSTRACTThe cooling dynamics of hot charge carriers in colloidal lead chalcogenide nanocrystals is studied by white light transient absorption spectroscopy. We demonstrate a transient accumulation of charge carriers at a high-energy critical point in the Brillouin zone. Using a theoretical study of the cooling rate in lead chalcogenides, we attribute this slowing down of charge carrier cooling to a phonon scattering bottleneck around this critical point. Our approach allows for the first ever determination of hot carrier cooling rates, relevant in e.g. modeling of multiple exciton generation.
Plasma-Reactor Wall Interactions: Bromine-Fluorine Chemistry Duality in an Industrial Dry Etch Process

Published: June 2015

ABSTRACTThe purpose of the present paper is to investigate the composition of the coating formed on the plasma reactor walls after an industrial process which is divided into two steps, where the chemistries used are CF4/CH2F2 followed by HBr/O2. Since Fluorine traces have been detected through the plasma and over the wafer even during the second chemistry, investigations of the Br-F chemistry duality for a new silicon etching process have been performed in order to see the reactions which are taking place inside of the reactor. The understanding of these formations is really important to avoid process instabilities and get better performance of the transistors. The coating on the walls after the process and after the cleaning between wafers has been characterized in order to figure out the level of F traces after each step and to understand the reminiscence of this element over time. This study is the starting point to propose a modification on the Waferless AutoClean (WAC) used nowadays in an industrial process.

Objective To understand the experience of families with children undergoing cleft surgery following adoption from a country outside the United States. To identify factors, including the timing of surgery, that influence family function throughout the surgical experience. Design Semistructured qualitative interviews were conducted with parents of internationally adopted children postrepair of cleft lip and/or cleft palate and coded by a multidisciplinary study team. Mixed methods were used to contextualize themes derived from the parent interviews. Results Twenty parent interviews were conducted, and four core themes were identified: (1) parental anxieties prior to surgery, (2) considerations for the timing of surgery, (3) impact of the surgical experience on the child and family, and (4) modifiable sociocontextual factors. Parents considered a strong child bond with at least one parent and the ability of the child to communicate basic needs to be important before undergoing surgery. In retrospect, parents generally felt that the surgical experience did not have a negative impact on their child or their families and that the surgical experience may have even facilitated bonding and attachment with their child. Acceleration of family bonding was expressed more often by parents of children who were adopted at older than 2 years. Conclusions In our study, parents reported that cleft surgery soon after international adoption did not appear to impair child bonding or adjustment. Specific family and provider factors that could optimize the experience for families were identified.

Authors: Gupta Richie , Gupta Rajat , Sethi Sameer , Khanal Manoj 
Published: June 2015

Soft palate palsy with or without pharyngeal or laryngeal paralysis or facial palsy has been described in the literature fewer than 40 times. Of these cases, isolated unilateral soft palate palsy (occurring without any other neurologic manifestation) has been rare. Most cases of isolated soft palate palsy were termed idiopathic in the past. In a few cases, a concomitant viral infection such as varicella zoster, herpes simplex, measles, and coxsackie A9 was diagnosed. We describe a case of isolated soft palate palsy, following a pharyngotonsillitis caused by Epstein-Barr virus. This viral infection has been linked in the past with bilateral facial nerve palsy and radial nerve palsy. Our patient recovered spontaneously over a period of 1 month.

Published: June 2015

Objectives. We examined Hispanic men’s recent risky and protective sexual behaviors with female partners by acculturation. Methods. Using the 2006–2010 National Survey of Family Growth, we performed bivariate analyses to compare acculturation groups (Hispanic Spanish-speaking immigrants, Hispanic English-speaking immigrants, Hispanic US natives, and non-Hispanic White men) by demographics and recent sexual behaviors with women. Multivariable logistic regression models for sexual behaviors by acculturation group were adjusted for demographics. Results. Compared with Hispanic Spanish-speaking immigrants, non-Hispanic White men were less likely to report exchange of money or drugs for sex (adjusted odds ratio [AOR] = 0.3; 95% confidence interval [CI] = 0.1, 0.9), but were also less likely to report condom use at last vaginal (AOR = 0.6; 95% CI = 0.4, 0.8) and anal sex (AOR = 0.4; 95% CI = 0.3, 0.7). Hispanic US natives were less likely to report condom use at last vaginal sex than were Spanish-speaking immigrants (AOR = 0.6; 95% CI = 0.4, 0.8). English- and Spanish-speaking immigrants did not differ in risky or protective sexual behaviors. Conclusions. Our findings suggest that targeted interventions focusing on unique sexual risks and sociodemographic differences by acculturation level, particularly nativity, may be helpful for preventing sexually transmitted infections.

Published: June 2015

Objectives. We examined how state characteristics in early life are associated with individual chronic disease later in life. Methods. We assessed early-life state of residence using the first 3 digits of social security numbers from blue- and white-collar workers from a US manufacturing company. Longitudinal data were available from 1997 to 2012, with 305 936 person-years of observation. Disease was assessed using medical claims. We modeled associations using pooled logistic regression with inverse probability of censoring weights. Results. We found small but statistically significant associations between early-state-of-residence characteristics and later life hypertension, diabetes, and ischemic heart disease. The most consistent associations were with income inequality, percentage non-White, and education. These associations were similar after statistically controlling for individual socioeconomic and demographic characteristics and current state characteristics. Conclusions. Characteristics of the state in which an individual lives early in life are associated with prevalence of chronic disease later in life, with a strength of association equivalent to genetic associations found for these same health outcomes.

Authors: Hogg Rachel A. , Mays Glen P. , Mamaril Cezar B. 
Published: June 2015

Objectives. We investigated changes in hospital participation in local public health systems and the delivery of public health activities over time and assessed the relationship between hospital participation and the scope of activities available in local public health systems. Methods. We used longitudinal observations from the National Longitudinal Survey of Public Health Systems to examine how hospital contributions to the delivery of core public health activities varied in 1998, 2006, and 2012. We then used multivariate regression to assess the relationship between the level of hospital contributions and the overall availability of public health activities in the system. Results. Hospital participation in public health activities increased from 37% in 1998 to 41% in 2006 and down to 39% in 2012. Regression results indicated a positive association between hospital participation in public health activities and the total availability of public health services in the systems. Conclusions. Hospital collaboration does play an important role in the overall availability of public health services in local public health systems. Efforts to increase hospital participation in public health may have a positive impact on the scope of services provided and population health in US communities.

Objectives. We sought to evaluate the impact of New York City’s (NYC’s) 2004 carbon monoxide (CO) alarm legislation on CO incident detection and poisoning rates. Methods. We compared CO poisoning deaths, hospitalizations, exposures reported to Poison Control, and fire department investigations, before and after the law for 2000 to 2010. Use of CO alarms was assessed in the 2009 NYC Community Health Survey. Results. Investigations that found indoor CO levels greater than 9 parts per million increased nearly 7-fold after the law (P < .001). There were nonsignificant decreases in unintentional, nonfire-related CO poisoning hospitalization rates (P = .114) and death rates (P = .216). After we controlled for ambient temperature, the law’s effect on hospitalizations remained nonsignificantly protective (incidence rate ratio = 0.747; 95% confidence interval = 0.520, 1.074). By 2009, 83% of NYC residents reported having CO alarms; only 54% also recently tested or replaced their batteries. Conclusions. Mandating CO alarms significantly increased the detection of potentially hazardous CO levels in NYC homes. Small numbers and detection bias might have limited the discovery of significant decreases in poisoning outcomes. Investigation of individual poisoning circumstances since the law might elucidate remaining gaps in awareness and proper use of CO alarms.
Engaging Law Enforcement in Overdose Reversal Initiatives: Authorization and Liability for Naloxone Administration
Authors: Davis Corey S. , Carr Derek , Southwell Jessica K. , Beletsky Leo 
Published: June 2015

Opioid overdose is reversible through the timely administration of naloxone, which has been used by emergency medical services for decades. Law enforcement officers (LEOs) are often the first emergency responders to arrive at an overdose, but they are not typically equipped with naloxone. This is rapidly changing; more than 220 law enforcement agencies in 24 states now carry naloxone. However, rollout in some departments has been hampered by concerns regarding officer and agency liability. We systematically examined the legal risk associated with LEO naloxone administration. LEOs can be authorized to administer naloxone through a variety of mechanisms, and liability risks related to naloxone administration are similar to or lower than those of other activities in which LEOs commonly engage.
Restatements: Do They Affect Auditor Reputation for Quality?
Authors: Irani Afshad J. , Tate Stefanie L. , Xu Le (Emily) 
Published: June 2015

SYNOPSIS
We examine whether an auditor's involvement with a financial statement restatement has a negative effect on their reputation as evidenced by both clients' and the market's assessments of audit firm quality. Specifically, we investigate the effect of auditor involvement with restatements on the non-restating clients' likelihood to dismiss their auditors in the year subsequent to restatement and on non-restating clients' market adjusted returns (MARs) around the restatement announcement date. We also investigate whether the severity of the restatements has a differential effect on both variables. We find non-restating clients are more likely to dismiss auditors as the number of restatements the auditor was involved with increases, and this likelihood increases with the number of restated items. In addition, non-restating clients' MARs are significantly negative around the restatement announcement date and are more negative with more severe restatements.
The Validity of Auditor Industry Specialization Measures
Authors: Audousset-Coulier Sophie , Jeny Anne , Jiang Like 
Published: June 2015

SUMMARY
In this research note, we examine the validity of the measures of auditor industry specialization in empirical archival audit research. Industry specialist auditors are auditors who have developed a specific expertise and are therefore able to provide high quality and more efficient services to their clients. Over the years, research scholars have developed a multiplicity of measures of industry specialization (ISP). We compare 30 ISP measures and find that the use of different ISP proxies results in inconsistent classifications of auditors as specialists. Using audit fee and earnings quality models, we further show that these inconsistencies have a significant effect on the inferences drawn from the models using ISP measures. We conclude that ISP measures exhibit a low degree of internal and external construct validity. This represents an important measurement challenge for researchers and casts some doubts on the robustness of prior empirical evidence found in auditor industry specialization research.
Antecedents to Unethical Corporate Conduct: Characteristics of the Complicit Follower
Authors: Mowchan Michael , Lowe D. Jordan , Reckers Philip M. J. 
Published: June 2015

ABSTRACT
Appropriately, researchers are devoting increased attention to the behavioral antecedents to unethical conduct in business. Prior management research, however, has focused primarily on destructive leaders while little research has focused on complicit followers, especially outside of the management literature. Thus, this paper examines three individual characteristics of followers—impulsivity, authoritarianism, and proactivity—in an accounting context. Two quasi-experiments are conducted to determine whether each characteristic influences an individual's intention for unethical complicity (Study 1) and ability to identify ethical dilemmas (Study 2). Results reveal that both high impulsivity and low authoritarianism lead to greater intention for unethical complicity and reduced ability to identify ethical dilemmas. Consistent with our prediction, high impulsivity and low authoritarianism interactively lead to the greatest intention for unethical complicity and lowest ability to identify ethical dilemmas. Additionally, in Study 1, high proactivity and high authoritarianism interactively lead to the greatest intention to resist supervisors' requests for compliant misconduct. Important contributions and implications for both theory and practice are also discussed.
Cisco Systems, Inc.: Minding the GAAP?
Authors: Jeffrey Cynthia G. , Perkins Jon D. 
Published: June 2015

ABSTRACT
Cisco Systems, Inc. manufactures and sells networking and communications products and provides services associated with that equipment and its use. In April 2001, Cisco announced a charge of $2.249 billion against earnings for obsolete inventory. The financial press gave extensive coverage to the write-off, including claims that Cisco was writing off inventory in an effort to set up future windfall profits. Students are required to examine and integrate information from multiple sources, including the relevant U.S. authoritative literature, SEC commentary relevant to Cisco's decision, and Cisco's disclosures, to critically evaluate reactions from the financial press and examine the potential for biased reporting in both Cisco's disclosures and the reactions of the financial press. This case is appropriate for an undergraduate intermediate accounting course or for graduate courses in financial statement analysis or accounting theory.

Background Autoimmune thyroid diseases are the most common of all autoimmune diseases. In the literature, Hashimoto thyroiditis (HT) is considered to be a T-helper (Th) type 1 dominant condition, and Graves disease is considered a Th2-dominant condition. Objective The aim of this study was to highlight a new aspect of the relationships among Th cell subgroups by determining the incidence of autoimmune thyroid disease in patients with allergic rhinitis (AR). Methods Patients were diagnosed with AR based on their medical histories, physical examinations, and skin-prick test results in an outpatient clinic. The levels of free triiodothyronine, free thyroxine, thyroid-stimulating hormone, thyroid peroxidase antibodies, and thyroglobulin antibodies were measured in peripheral blood samples from all study subjects. Results A total of 1239 patients with AR and 700 consecutive, age- and sex-matched healthy subjects were included in the study. Thyroid function tests showed that 1037 patients with AR (83.7%) had normal thyroid function, 171 (13.8%) had euthyroid HT, and 31 (2.5%) had hypothyroid HT. Among the control subjects, thyroid function test results showed that 688 subjects (98.2%) had normal thyroid function, 10 subjects (1.4%) had euthyroid HT, and 2 subjects(0.4%) had hypothyroid HT. Conclusion The incidence of HT in the general population is 1.5%; in contrast, it was observed in 16.3% of our patients with AR, which represented a much higher rate than that in the overall population. Graves disease was not detected in our study subjects. A high incidence of HT in patients with AR, in which Th2 responses are dominant, indicates that further studies of the relationships among atopy, autoimmune diseases, and Th cell subgroups are needed.
