Morphology and properties of a photopolymer/clay nanocomposite prepared by a rapid prototyping system
Authors: Chiu Shih-Hsuan , Wicaksono Sigit Tri , Chen Kun-Ting , Pong Sheng-Hong
Published: July 2013

This study represents an in situ polymerization by preparation of tetrafunction polyester acrylate mixed with 1,6-hexanediol diacrylate/clay nanocomposite by digital light processor rapid prototyping. The morphology of nano-clay fillers and the dispersing agent in the photopolymer matrix are investigated by scanning electron microscopy (SEM). Degradation temperature, tensile strength, impact strength, and hardness are characterized by using thermogravimetric analysis, universal tensile machine, Izod impact tester, and hardness shore A tester, respectively. Results show that the effect of clay loading with an appropriate amount of dispersant tends to significantly increase not only the tensile strength and hardness but also the degradation temperature of photopolymer/clay nanocomposite; however, the impact strength is not affected. In the same conditions, as visualized on SEM images, the nanocomposite tends to form the exfoliated structure with agglomeration of clay, which is caused by uneven distribution of nano-clay in the photopolymer matrix.

Published: July 2013

Insulin resistance is a well-documented risk factor for the development of endometrial cancer. Adiponectin and vaspin are insulin-sensitizing proteins that are secreted from adipose tissue. A clear association between serum levels of adipokines and endometrial cancer has yet to be established. The study group consisted of postmenopausal women with confirmed endometrial cancer, whereas patients with benign endometrial conditions constituted the control group. The two groups were compared in terms of insulin resistance and serum levels of adiponectin and vaspin. A total of 60 patients with confirmed endometrial cancer and 70 controls with benign endometrial conditions (polyps and atrophy) were enrolled. Median homeostasis model assessment of insulin resistance value was significantly higher in the study group compared with the control group (2.93 vs 1.27, P<0.0001), whereas mean quantitative insulin sensitivity check index value was significantly lower (0.33±0.02 vs 0.37±0.37, P<0.0001). Median values for both adiponectin and vaspin were significantly lower in patients with endometrial cancer compared with the control group (4.09 vs 17.13 μg/ml, P<0.0001 and 0.21 vs 0.39 ng/ml, P<0.0001 respectively). Low levels of both adiponectin and vaspin were found to be significantly associated with an increased risk for endometrial cancer. Following adjustment for confounding factors, the respective odds ratios for endometrial cancer in patients in the first tertile compared with those in the third tertile were 10.80 (2.76–42.24; P=0.001) and 13.23 (2.94–59.64; P=0.001). Our results show that lower levels of circulating adiponectin and vaspin levels are associated with an increased risk of developing endometrial cancer.
Cathepsin B activity has a crucial role in the developmental competence of bovine cumulus–oocyte complexes exposed to heat shock during in vitro maturation

Published: July 2013

Cathepsin B was found to be correlated inversely with the quality of bovine oocytes and embryos. The aims of this study were to evaluate i) the relationship between heat shock duringin vitromaturation (IVM) of bovine cumulus–oocyte complexes (COCs) and cathepsin B activity in relation to apoptosis and ii) the effect of supplementation of cathepsin B inhibitor (E-64) during IVM of heat-shocked COCs on embryonic development. After IVM at 38.5 °C for 22 h (control group) or at 38.5 °C for 5 h followed by 41 °C for 17 h (heat shock group) either with or without 1 μM E-64, activities and protein expression of cathepsin B and caspase 3 were evaluated as well as TUNEL staining. After IVF, developmental rate, total cell number, and the percentage of apoptotic cells in blastocysts were evaluated on day 8 (day 0, IVF day). Heat-shocked IVM COCs showed significantly high activities and expressions of both cathepsin B, and caspase 3 accompanied by a significant increase in number of TUNEL-positive cells. Addition of E-64 significantly decreased the activities of cathepsin B and caspase 3, and TUNEL-positive cells in heat-shocked IVM COCs. Moreover, addition of 1 μM E-64 during IVM under heat shock conditions significantly improved both developmental competence and quality of the produced embryos. These results indicate that heat shock induction of cathepsin B is associated with apoptosis of COCs, and inhibition of cathepsin B activity can improve the developmental competence of heat-shocked COCs during IVM.

Authors: Kamlin C. Omar F. , Schilleman Kim , Dawson Jennifer A. , Lopriore Enrico , Donath Susan M. , Schmölzer Georg M. , Walther Frans J. , Davis Peter G. , te Pas Arjan B.
Published: July 2013

OBJECTIVE:

Positive-pressure ventilation (PPV) using a manual ventilation device and a face mask is recommended for compromised newborn infants in the delivery room (DR). Mask ventilation is associated with airway obstruction and leak. A nasal tube is an alternative interface, but its safety and efficacy have not been tested in extremely preterm infants.

METHODS:

An unblinded randomized controlled trial was conducted in Australia, and the Netherlands. Infants were stratified by gestational age (24–25/26–29 weeks) and center. Immediately before birth infants were randomly assigned to receive PPV and/or continuous positive airway pressure with either a nasal tube or a size 00 soft, round silicone mask. Resuscitation protocols were standardized; respiratory support was provided using a T-piece device commencing in room air. Criteria for intubation included need for cardiac compressions, apnea, continuous positive airway pressure >7 cm H2O, and fraction of inspired oxygen >0.4. Primary outcome was endotracheal intubation in the first 24 hours from birth.

RESULTS:

Three hundred sixty-three infants were randomly assigned; the study terminated early on the grounds of futility. Baseline variables were similar between groups. Intubation rates in the first 24 hours were 54% and 55% in the nasal tube and face mask groups, respectively (odds ratio: 0.97; 95% confidence interval: 0.63–1.50). There were no important differences in any of the secondary outcomes within the whole cohort or between the 2 gestational age subgroups.

CONCLUSIONS:

In infants at <30 weeks’ gestation receiving PPV in the DR, there were no differences in short-term outcomes using the nasal tube compared with the face mask.
A Genome-Wide Association Study (GWAS) for Bronchopulmonary Dysplasia

Published: July 2013

OBJECTIVE:

Twin studies suggest that heritability of moderate-severe bronchopulmonary dysplasia (BPD) is 53% to 79%, we conducted a genome-wide association study (GWAS) to identify genetic variants associated with the risk for BPD.

METHODS:

The discovery GWAS was completed on 1726 very low birth weight infants (gestational age = 250–296/7 weeks) who had a minimum of 3 days of intermittent positive pressure ventilation and were in the hospital at 36 weeks’ postmenstrual age. At 36 weeks’ postmenstrual age, moderate-severe BPD cases (n = 899) were defined as requiring continuous supplemental oxygen, whereas controls (n = 827) inhaled room air. An additional 795 comparable infants (371 cases, 424 controls) were a replication population. Genomic DNA from case and control newborn screening bloodspots was used for the GWAS. The replication study interrogated single-nucleotide polymorphisms (SNPs) identified in the discovery GWAS and those within the HumanExome beadchip.

RESULTS:

Genotyping using genomic DNA was successful. We did not identify SNPs associated with BPD at the genome-wide significance level (5 × 10−8) and no SNP identified in previous studies reached statistical significance (Bonferroni-corrected P value threshold .0018). Pathway analyses were not informative.

CONCLUSIONS:

We did not identify genomic loci or pathways that account for the previously described heritability for BPD. Potential explanations include causal mutations that are genetic variants and were not assayed or are mapped to many distributed loci, inadequate sample size, race ethnicity of our study population, or case-control differences investigated are not attributable to underlying common genetic variation.
Essential Contractual Language for Medical Necessity in Children

Published: July 2013

The previous policy statement from the American Academy of Pediatrics, “Model Language for Medical Necessity in Children,” was published in July 2005. Since that time, there have been new and emerging delivery and payment models. The relationship established between health care providers and health plans should promote arrangements that are beneficial to all who are affected by these contractual arrangements. Pediatricians play an important role in ensuring that the needs of children are addressed in these emerging systems. It is important to recognize that health care plans designed for adults may not meet the needs of children. Language in health care contracts should reflect the health care needs of children and families. Informed pediatricians can make a difference in the care of children and influence the role of primary care physicians in the new paradigms. This policy highlights many of the important elements pediatricians should assess as providers develop a role in emerging care models.

This clinical report updates a 2005 report from the American Academy of Pediatrics on the evaluation of sexual abuse in children. The medical assessment of suspected child sexual abuse should include obtaining a history, performing a physical examination, and obtaining appropriate laboratory tests. The role of the physician includes determining the need to report suspected sexual abuse; assessing the physical, emotional, and behavioral consequences of sexual abuse; providing information to parents about how to support their child; and coordinating with other professionals to provide comprehensive treatment and follow-up of children exposed to child sexual abuse.
Interobserver reproducibility of Gleason grading in prostate biopsy samples
Authors: Bori Rita , Salamon Ferenc , Móczár Csaba , Cserni Gábor
Published: July 2013

Introduction: Gleason grading is the most common method of prostate cancer classification. Aim: The aim of the authors was to assess the reproducibility of Gleason grading among pathologists using the same needle biopsy samples. Method: 23 pathologists examined 37 prostate cancer biopsies stained with hematoxylin and eosin. Gleason scores were categorised into 4 groups (2–4, 5–6, 7 and 8–10). Kappa statistics were used to reflect interobserver agreement. Results: Considering all participating pathologists, grouping into one of the 4 categories resulted in an overall kappa value of 0.49. For the individual categories, the worst agreement (kappa = 0.15) was seen with well differentiated carcinomas, and the best (kappa = 0.65) with poorly differentiated ones. Conclusions: These results suggest that Gleason grading in biopsy samples is moderately reproducible. The kappa values vary according to the differentiation of the cancer, and there is not much difference between the results of the present study and those published in the literature. To increase reproducibility, trainings should be organised, and this could improve the quality of grading. Orv. Hetil., 2013, 154, 1219–1225.
Flow cytometry: is this a novelty in microbiological diagnostics?
Authors: Pállinger Éva
Published: July 2013

Direct detection of pathogens is time- and labor-intensive. There is an increasing demand for new rapid microbiological testing methods, which would be faster and more sensitive than the conventional ones. Initally, automated methods were applied for the testing of bacteremia, urinary tract infections, characterization of antimicrobial susceptibility and quantitation of pathogen specific antibodies. Recently the nucleic acid-based detection methods have also become a routine. The molecular biological methods accelerate diagnosis, enhance specificity and provide an opportunity to identify pathogens with potential difficulties in culturing. However, they do not give any information about the immune status of the host. Yet it should also be borne in mind that detection of pathogen-specific nucleic acids is not equivalent to the presence of living microbes. The greatest advantage of FACS against these techniques is the capability to identify individual microbial cells as well. High speed FACS becomes a priority in the characterization of slow-growing microbes and identification of pathogens in mixed infections. Last but not least, it allows the monitoring of immune status and follow up of antimicrobial therapy. Orv. Hetil., 2013, 154, 1207–1218.

Published: July 2013

Conservation of free‐ranging cheetah (Acinonyx jubatus) populations is multi faceted and needs to be addressed from an ecological, biological and management perspective. There is a wealth of published research, each focusing on a particular aspect of cheetah conservation. Identifying the most important factors, making sense of various (and sometimes contrasting) findings, and taking decisions when little or no empirical data is available, are everyday challenges facing conservationists. Bayesian networks (BN) provide a statistical modeling framework that enables analysis and integration of information addressing different aspects of conservation. There has been an increased interest in the use of BNs to model conservation issues, however the development of more sophisticated BNs, utilizing object‐oriented (OO) features, is still at the frontier of ecological research. We describe an integrated, parallel modeling process followed during a BN modeling workshop held in Namibia to combine expert knowledge and data about free‐ranging cheetahs. The aim of the workshop was to obtain a more comprehensive view of the current viability of the free‐ranging cheetah population in Namibia, and to predict the effect different scenarios may have on the future viability of this free‐ranging cheetah population. Furthermore, a complementary aim was to identify influential parameters of the model to more effectively target those parameters having the greatest impact on population viability. The BN was developed by aggregating diverse perspectives from local and independent scientists, agents from the national ministry, conservation agency members and local fieldworkers. This integrated BN approach facilitates OO modeling in a multi‐expert context which lends itself to a series of integrated, yet independent, subnetworks describing different scientific and management components. We created three subnetworks in parallel: a biological, ecological and human factors network, which were then combined to create a complete representation of free‐ranging cheetah population viability. Such OOBNs have widespread relevance to the effective and targeted conservation management of vulnerable and endangered species.
Fetal Monitoring: Creating a Culture of Safety With Informed Choice
Authors: Heelan Lisa
Published: July 2013

The dominant culture in labor and birth is the medical model, not the midwifery model of woman-centered care. Consensus among professional and governmental groups is that, based on the evidence, intermittent auscultation is safer to use in healthy women with uncomplicated pregnancies than electronic fetal monitoring (EFM). Barriers impact the laboring woman’s ability to give informed choice regarding fetal monitoring. Lack of informed choice denies a woman her right to be in control of her birth experience, and is in opposition to a woman’s right to autonomy and self-determination.
A Case Study of Real-Time Integrated Formation Evaluation and Horizontal Wellbore Placement in a Thin-Bedded Reservoir
Authors: Ortenzi Luca , Okoroafor Rita E. , Jain Vikas
Published: July 2013

Many reservoirs in the Gulf of Guinea are sequences of permeable sands interbedded with variable proportions of silt and clay. The sands are typically permeable, but the silt and clay are not, determining a high degree of vertical heterogeneity. Some of these reservoirs are also highly depleted, with thin oil columns delimited by encroaching gas caps and aquifers.

Horizontal wells are a proven way to produce mature reservoirs with high permeability contrast. However, the higher construction costs and technical complexity demand the utmost care in their placement. To this end, pilot holes are drilled in order to exactly identify the target zones. The task to precisely identify the sweet spots where to place the horizontal wellbore is sometimes challenging.

For start, thin-beds reservoirs are traditionally difficult to evaluate quantitatively. This is especially true in depleted reservoirs, where hydrocarbons identification is complicated by their reduced volumes and corresponding diminished effect on typical logs. Fresh connate water increases the uncertainty of traditional resistivity-based saturation methods. The highly variable permeability complicates the task of acquiring and interpreting formation pressure. Lastly, operational reasons may prevent the use of wire-line-conveyed logging devices and associated methods.

This paper presents a case where multiple formation evaluation challenges were addressed in real time and quasi-real time by the integrated interpretation of advanced logging-while-drilling (LWD) data.
Using Gas Turbine for Electricity supply in a Typical Nigerian University: A Case Study of University of Port Harcourt
Authors: Chidinma Uzoho
Published: July 2013

Abstract

Global warming, or the 'greenhouse effect' is an environmental issue that deals with the potential for global climate change due to increased levels of atmospheric 'greenhouse gases'. Natural gas offers a variety of environmental benefits and environmental friendly uses. It is becoming an increasingly important fuel in the generation of electricity.

Power generating companies and other users of industrial gas would later in the year begin to pay more for the commodity after the Federal Government approved a 400% increase in price of gas to power for the domestic market. The new price is capped at $3 per thousand cubit feet. Mrs. Allison-Madueke (Minister of Petroleum Resources) said Government decided to harmonize the domestic and export market rates so as to attract investment in the gas sector and make the domestic gas market more attractive for its operators.

In this study, the feasibility of using gas to power UNIPORT and it's environ was considered since there is proximity to source of gas (Agbada Flow Station 1, Aluu, Rivers State). An economic evaluation was done using real and estimated values of the input parameters. The old gas price and tariff of electricity with the new gas price and estimated tariff of electricity were used for economic evaluation to create a cashflow model then get the NPV's , IRR, DPIR,GRR, and the Payback Periods which were used as the profitability indicators for this investment.
The Use of Antidepressants in the Long-Term Treatment Should not Improve the Impact of Fibromyalgia on Quality of Life
Authors: Carta MG , Ruggiero V , Sancassiani F , Cutrano F , Manca AR , Peri M , Fais A , Cacace E
Published: July 2013

Background:

Antidepressant (AD) drugs are effective in the short term treatment of fibromyalgia (FM). It may be useful to study the long-term impact of AD on patients with FM.

Methods:

One-year follow-up study on 23 females with FM divided into groups on AD (ADg-N=7), and not taking AD (NADg-N=11). Evaluation at t1 and at the end (t2) with the Fibromyalgia Impact Questionnaire (FIQ); at t2 with: SCID-IV; Mood Disorder Questionnaire (MDQ); Short Form-12; Hamilton Depression Rating Scale (HAM-D); Functioning Assessment Short Test (FAST)

Results:

After a year the AD group showed a worst impact of the disease by FIQ (p=0.017), worsened quality of life by SF-12 (p<0.01), and disability linked to bipolar symptoms by FAST (p=0.05). About 40% of the sample was screened positive at MDQ without difference in the two groups. The patients who recovered from a depressive episode did not differ between ADg and NADg (20% vs 33.3%), and were fewer than expected from the literature (40-60%). The HAM-D score at the end of the trial was worse in the ADg (p<0.03).

Limitations:

Observational research on few patients, not specifically designed to test the hypothesis. The results have a heuristic value only.

Discussion:

The results should be read in the light of the high prevalence of patients screened positive for Bipolar Disorders and of the well-known poor response of the mood symptoms to antidepressants in Bipolar Depression. The deterioration in the long-term management of FM patients following AD treatments suggests the need for new and robust studies.
Delusional Disorder and Oncology: Review of the Literature and Case Report
Authors: Pearman Timothy P.
Published: July 2013

Objective:

Delusional disorder is an infrequent diagnosis in outpatient clinical practice. While delusional thought processes are a fairly common part of symptom clusters in chronic psychiatric disorders such as schizophrenia and bipolar disorders, true delusional disorders are believed to be fairly rare.

Method:

In this article, we review scientific data on incidence, diagnosis, and treatment of delusional disorders. This was done by PubMed search utilizing the search terms “delusional disorder,” “oncology,” “diagnosis,” and “treatment.” Relevant articles were excluded if they dealt predominantly with schizophrenia instead of primary delusional disorder.

Results:

We present a case of a patient diagnosed with follicular lymphoma and an apparent longstanding history of persecutory delusions. The patient's symptoms eventually led to intervention in the oncology practice involving the medical center faculty and staff, as well as local police and the court system.

Conclusions:

Delusional disorder is an under-researched condition, and limited information is known regarding the treatment of this condition when it impacts upon medical care. Future research directions are proposed.
Constrained Agency in Corporate Social Media Policy
Authors: Weber Ryan
Published: July 2013

Corporate social media policies construct what Herndl and Licona term “constrained agency,” an ambiguous, contradictory agent function. Drawing on an analysis of 31 corporate social media policies, this article argues that these policies create constrained agency in two ways: they establish contradictory expectations for a writer's voice by requesting both individual and corporate-friendly voices, and they create a seemingly paradoxical situation where employees both do and do not represent the company. These policies shed light on the complex constructions of agency within corporations and encapsulate the workplace tensions that accompany the affordances of social media tools.
Production of L-lactic acid from Cassava peel wastes using single and mixed cultures of Rhizopus oligosporus and Lactobacillus plantarum
Authors: Nwokoro Ogbonnaya
Published: July 2013

Production of L-lactic acid using cultures of Rhizopus oligosporus and
Lactobacillus plantarum was investigated. Cassava peels were hydrolyzed by
boiling for 1 h in either NaOH or HCl solutions followed by neutralization to
a pH of 6.2. Reducing sugar produced from the hydrolysates increased with
increasing concentrations of alkali or acid. Samples hydrolyzed with HCl
produced a maximum reducing sugar concentration of 402 mg/g substrate while
alkali hydrolyzed samples produced a maximum reducing sugar concentration of
213 mg/g substrate. Hydrolysates were amended with 0.5% ammonium sulphate
solution and inoculated with either single or mixed cultures of Rhizopus
oligosporus and Lactobacillus plantarum and incubated for 48 h for lactic
acid production. The best lactic acid production of 50.2 g/100g substrate was
observed in a mixed culture fermentation of acid hydrolyzed peels. Mixed
culture fermentation of alkali hydrolyzed peels produced a maximum lactic
acid concentration of 36.4 g/100g substrate. Un hydrolyzed cassava peels
inoculated with a mixed culture of the microorganisms produced only 4.6
g/100g substrate. This work reports an efficient use of cassava peels for
bio-product formation through microbial fermentation.
Evaluation of a Workshop to Reduce Negative Perceptions of Statistics in Undergraduate Psychology Students
Authors: Hood Michelle , Neumann David L.
Published: July 2013

The authors evaluated whether a brief group workshop that combined psycho-education and learning strategies improved self-efficacy, attitudes, and anxiety regarding statistics in psychology students. The workshop was completed in Week 1 of a compulsory 1st-year psychology statistics course. Prior to the workshop, the attendees ( n = 10) did not differ from the non-attending control group ( n = 17) on statistics self-efficacy, attitudes, or anxiety. These measures were re-assessed after the workshop near the end of semester (Week 10). Workshop attendance resulted in significantly higher self-efficacy, computational self-concept, and attitudes regarding the worth of statistics, and less fear of statistics teachers. It did not change statistics anxiety. Participants evaluated the workshop as useful, especially the information on effective learning strategies. The results demonstrate that a brief and cost-effective group intervention can improve self-efficacy and attitudes regarding statistics. Improvements to better target anxiety are discussed.
The Effectiveness of Epistemic Beliefs and the Role of Self-efficacy in the Solving of Cross-curricular Problems
Authors: Heigl Nicole Romana , Thomas Joachim
Published: July 2013

Graduates expect higher education to provide both subject-specific knowledge as well as cross-curricular competencies in order to handle new and unknown situations in their professional life. In this regard, it is problematic that the latter construct is still both theoretically and empirically vague. In addition, concerning the fostering of cross-curricular competencies, higher education often neglects the interplay of cognitive, metacognitive and motivational skills. This article will address these shortcomings. Based on an empirical study with German university students analyzing cross-curricular problem-solving competencies, a diagnostic model for measuring these competencies will be outlined. Subsequently, the article will present results that show connections between cross-curricular problem solving and motivational and metacognitive skills, notably self-efficacy and epistemological beliefs. These results show that cross-curricular problem-solving competencies depend on how much students regard knowledge as flexible and modifiable. In addition, it could be observed that self-efficacy seems to assume a relevant role. Once more, the results underline the importance of the promotion of epistemological beliefs, in particular critical thinking and reflexivity, as well as encouraging students to experience their own competence.
Peer Mentoring to Develop Psychological Literacy in First-Year and Graduating Students
Authors: Burton Lorelle J. , Chester Andrea , Xenos Sophie , Elgar Karen
Published: July 2013

First- and final-year undergraduate students have unique transition issues. To support both the transition of first-year students into the program, and the transition of third-year students out of the program and into the workforce or further study, a face-to-face peer mentoring program was embedded into the first-year psychology curricula at RMIT University, Melbourne, Australia. The 34 peer mentors, third-year students taking a course on mentoring and career preparation, worked in pairs with small groups of first-year students ( N = 231) in class time to help them develop study skills that underpin the first-year assessment tasks. This article reports on a peer mentoring program designed to develop and consolidate psychological literacies of both first- and third-year students. Comparing pre-and post-tests for first-year students, there was a significant increase in self-ratings across 8 of the 9 ability areas used to measure psychological literacy. In contrast, third-year mentors only showed significant change in the ability to understand basic psychological concepts. Correlational data reveal, for mentees, final course grades were significantly correlated with domain-specific psychological literacy, comprising knowledge and understanding of basic psychological concepts, scientific research practices, application of psychology, and ethics; for mentors, final course grades were significantly correlated with general psychological literacy, comprising cultural competence, critical thinking, problem solving, communication, and self-awareness skills. While first-year students indicated an overall positive experience with the mentoring program, the third-year mentors showed strong support for the program. The key implications are discussed.

In an attempt to influence students' appreciation of the value of research, the authors introduced a multidimensional scaling activity in a section of introductory psychology. In two consecutive 80-minute classes, 32 students worked in pairs, categorizing 20 crimes on the basis of similarity and coding their partner's responses, and then worked in groups of 4, interpreting a 2-dimensional solution of the pooled data. The students' appreciation of the value of research was assessed at the beginning and end of the course, using a second section of 36 students as a comparison group. It was found that appreciation of research increased significantly in the section that completed the activity. The authors recommend incorporating research activities into introductory courses.
Employability of Psychology Graduates and their Job Satisfaction in Turkey: An Online Survey
Authors: Sümer Nebi , Helvaci Elif , Misirlisoy Mine
Published: July 2013

The interest in studying psychology has dramatically increased in the recent decades in Turkey. However, only 60% of psychology graduates work in jobs related to psychology. Moreover, there is no data on employability and job distribution of psychology graduates or on their job satisfaction. In the current study, the authors' first aim was to assess the employability of psychology graduates, and their job satisfaction in Turkey. Secondly, they examined the specific advantages of having a postgraduate degree over a bachelor's degree. Using an online survey they compared psychologists with and without postgraduate degrees on different aspects of employability as well as their job satisfaction, income, and promotion opportunities. Results showed that psychology graduates were mostly working in clinical and educational settings, and about half of them had a postgraduate degree. The majority of psychologists were somewhat satisfied with their jobs. Additionally, the authors found that having a postgraduate degree, compared to a bachelor's degree, meant less time spent on job searching, a higher salary, and higher job satisfaction. Findings are discussed in relation to teaching of psychology and challenges that face psychology graduates regarding employability in Turkey.
The Association between Actuarial Services and Audit Quality
Authors: Gaver Jennifer J. , Paterson Jeffrey S.
Published: July 2013

We examine the association between audit quality and the joint provision of audit and non-audit services (NAS) by accounting firms. We argue that differences in audit quality between joint and non-joint NAS conditions can only be assessed if the quality of the NAS service is held constant. Most prior work has not been able to do this because the identity of the NAS provider is unknown unless it is the audit firm itself. Our analysis is based on firms in the property-casualty insurance industry that purchase an actuarial certification of their loss reserves from an external party. The insurance setting is unique because the non-audit service that we examine is purchased by all firms in our sample, and we can identify both the audit and non-audit service provider. This allows us to directly address the NAS separation issue while holding NAS quality constant. We find that when actuarial work is obtained only from Big N firms (NAS quality is constant), audit quality is higher when separate Big N firms provide audit and actuarial services. The implication is that separating audit and NAS functions between two quality providers is beneficial, compared to allowing one quality firm to provide both services. We caution that this finding may not apply to other types of non-audit services, and a blanket prohibition on these activities is not warranted.

Published: July 2013

The cause and pathogenesis of gastroschisis are uncertain. We report the autopsy and placental pathology of a stillbirth at 20 gestational weeks, in which gastroschisis was accompanied by destructive lesions in the cerebral cortex and brainstem, as well as cardiac calcification, consistent with ischemic injury during the 2nd trimester. An important potential underlying mechanism explaining the fetal abnormalities is the presence of infarcts in the placenta, indicative at this gestational age of maternal vascular underperfusion. The association of gastroschisis with ischemic lesions in the brain, heart, and placenta in this case supports the concept that gastroschisis, at least in some instances, may result from vascular event(s) causing disruption of the fetal abdominal wall and resulting in the extrusion of the abdominal organs, as well as hypoxic–ischemic brain and cardiac injury.
In situ hybridization-based detection of microRNAs in human diseases
Authors: Zhang Xinna , Lu Xiongbin , Lopez-Berestein Gabriel , Sood Anil K. , Calin George
Published: July 2013

MicroRNAs (miRNAs) are small non-coding RNAs that regulate various aspects of gene expression in physiology and development. Links between miRNAs and the initiation and progression of human diseases are becoming increasingly apparent. The development of methods to detect the subcellular and tissue localization of miRNAs is essential for understanding their biological role in homeostasis. In this review, we discuss how in situ hybridization can complement tissuelevel miRNA expression profiling and its role as an investigational tool to better understand the etiology of human diseases. Furthermore, in situ hybridization of miRNAs represents a potent diagnostic assay that could be further refined and utilized for clinical applications.

Distribution and Habitat of the Malaysian Species of Lejeunea (Marchantiophyta: Lejeuneaceae), with Description of Lejeunea Tamaspocsii Sp. Nov.
Authors: Ee Lee Gaik , Gradstein S. Robbert
Published: July 2013

We analyze the geographical and elevational ranges and the habitats of 30 species and two varieties of Lejeunea Lib. recorded from Malaysia. The greatest diversity of Lejeunea in Malaysia is found on Mt. Kinabalu with 27 species. The majority of the species are Malesian in distribution with a high number (8) belonging to the West Malesian element. Widely distributed species are often autoicous and produce spores freely; those with narrow distributions are more often dioicous and rarely produce spores. Dispersal of dioicous species seems to be promoted by asexual reproduction, being more common in wide-ranging dioicous species than in narrow-ranging ones. Endemism is 10% with three species being known only from Mt. Kinabalu. Range sizes of species decrease towards higher elevation and endemic species occur exclusively in the mountains. About half of the species occur in the lower montane rainforest belt, which is the elevational zone with the highest diversity of Lejeunea in Malaysia. The majority of the species are epiphytes, either corticolous or ramicolous. One species (L. dimorpha) is an obligate epiphyll. The new species Lejeunea tamaspocsii G. E. Lee is described and two new combinations, L. dipterota (Eifrig) G. E. Lee and L. exilis var. abnormis (Herzog) G. E. Lee, are proposed.
A New Terrestrial Genus and Species Within the Aquatic Liverwort Family Riellaceae (Sphaerocarpales) from Australia
Authors: Cargill D. Christine , Milne Josephine
Published: July 2013

A new genus Austroriella Cargill & Milne and species Austroriella salta Milne & Cargill within the family Riellaceae is described. Known only from the type location at the margins of a saline lake in Western Australia it is the first record and description of a terrestrial species within this typically aquatic family. Female plants are typical of the family with a single reduced wing bearing a row of archegonia; male plants are not typical and are naviculate in form enclosing several rows of enclosed antheridia not unlike the males of Sphaerocarpos. Unlike Sphaerocarpos this species does bear oil bodies. Differences and affinities are also outlined briefly with closely related genera within the order Sphaerocarpales.

Jubula Hutchinsiae Subsp. Caucasica Konstant. & Vilnet (Marchantiophyta: Jubulaceae) – New for the Bryophyte Flora of Iran and Turkey
Authors: Kürschner Harald
Published: July 2013

Jubula hutchinsiae (Hook.) Dumort. forms a complex of notoriously difficult intraspecific taxa, recorded from Southwest Asia as J. hutchinsiae subsp. javanica (Steph.) Verd. A re-examination of the Iranian and Turkish records indicates that they belong to the recently described J. hutchinsiae subsp. caucasica Konstant. and Vilnet, which seem to be restricted to the broadleaved deciduous forests of the Euxine-Caucasian-Hyrcanian floral province.

Published: July 2013

Dominican amber is an important source for Early Miocene bryophytes. We report the moss Macromitrium richardii Schwägr., an extant representative of the Orthotrichaceae, from the Dominican amber collection of the American Museum of Natural History. This species is currently a widespread Neotropical epiphyte. The specimen includes several gametophytes and sporophytes, and represents the first fossil record of Orthotrichaceae. Alongside the Macromitrium shoots we observed several fragments of the liverworts Cheilolejeunea antiqua and Frullania sp. The unusual thermal behavior of the resin sample initially led to doubts about the Miocene age of the specimen, but chemical analyses of the Hymenaea resin provides evidence that the specimen represents a highly oxidized sample of Miocene Dominican amber rather than an artificially thermally-treated subfossil resin (copal). Our inclusion demonstrates the exceptional preservation potential of tree resin, but our observations also suggest that provenance (including any possibility that a modern resin has been thermally treated to make it appear older) should be scrutinized when single pieces with atypical thermal behavior and exceptionally well-preserved extant morphotypes come to light.
Brachymenium Regnellii and Bryum Leptotorquescens (Bryaceae) New to Suriname
Authors: Allen Bruce
Published: July 2013

The previously Brazilian endemic species, Brachymenium regnellii Hampe, has been found in Suriname. It is a member of sect. Rostrata Ochi, distinguished from all other members of that section in Suriname by its percurrent costae. Brachymenium Schwägr. is characterized by the sporophytic features of: erect to suberect capsules; conic-apiculate to short-beaked opercula; and diplolepideous peristomes with narrow, densely papillose exostome teeth and greatly reduced endostomes. Bryum leptotorquescens Müll. Hal ex Broth., previously known from Mexico to western South America, and tropical Africa is reported from Suriname. It differs from other similar mosses in Suriname by the combination of weakly developed leaf borders; strongly decurrent leaves; and costae in cross section with well-developed stereid bands. Bryum billarderei Schwägr. is the correct spelling of that often mis-spelled name.
