Published: May 2016

Abstract
The aim of this paper is to derive explicitly a connection between the Zagier elliptic trilogarithm and Mahler measures of certain families of three-variable polynomials defining
K3 surfaces. In addition, we prove some linear relations satisfied by the elliptic trilogarithm evaluated at torsion points on elliptic curves.
Conflicts of interest in randomised controlled surgical trials: systematic review and qualitative and quantitative analysis

Published: May 2016

AbstractConflicts of interest may lead to biased trial designs and unbalanced interpretation of study results. We aimed to evaluate the reporting of potential conflicts of interest in full publications of surgical randomised controlled trials (RCTs). A systematic literature search was performed in CENTRAL, MEDLINE and EMBASE (1985–2014) to find all surgical RCTs of medical devices and perioperative pharmacological or nutritional interventions. The information on conflicts of interest was evaluated both quantitatively and qualitatively, and the development of stated conflicts over time was studied. Of 7934 articles, 444 met the inclusion criteria. In 93 of 444 trials (20.9%), conflicts of interest were disclosed. In half of the cases, the information provided was insufficient to permit conclusions regarding possible influence on the trials. Information about conflicts of interest has increased continuously during the last decades (1985–1994: 0%, 1995–2004: 2.8% and 2005–2014: 33.0%; p<0.001). Among the 115 industry-funded trials, industry participation was considered as a potential conflict of interest in 24 cases (20.9%). Over the past three decades, only every 10th trial has provided appropriate information on conflicts of interest. However, transparency is crucial for the reliability of evidence-based medicine. There is an urgent need for the full disclosure of all conflicts of interest in surgical publishing and for transparency regarding cooperation between academia and industry.

This articles discusses the life of Nyai Dadah, a woman leader of pesantren in Central Java Indonesia, through life history method, to shed light upon the gender elasticity of pesantren and the struggle of its woman to promote girls education in Indonesia. Nyai Dadah is the eldest daughter of Kiai Zubaidi, the founder of Pesantren Al Asror. When her father passed away, she continued the struggle of her father managing the pesantren. His younger brother was still in religious training, and when he completed the study she passed the leadership to him and then created a pesantren for girls. The study reveals that pesantren women have strategies to promote girls education and pesantren doesnot close itself from the rise of women’s leadership. Nyai Dadah with her capabilities is able to manage the pesantren for girls. Nyai Dadah plays the roles either as a nyai in pesantren or a housewife, and religious leader in her village.Menggunakan metode life history, penelitian ini bertujuan untuk mengungkapkan secara detil ketokohan seorang figur perempuan atau pemimpin pesantren di Semarang, yang disebut sebagai nyai. Life history nyai digunakan untuk menyampaikan perjuangan dan peran beliau di pesantren dan masyarakat. Nyai yang dikaji dalam penelitian ini adalah Nyai Dadah, anak perempuan tertua dari Kiai Zubaidi, pendiri Pesantren Al Asror, yang sekarang menjadi nyai di Pesantren Putri Huffadhul Quran Al Asror sejak tahun 2002 hingga sekarang. Studi ini berdasarkan pada konsep life history dan teori negosiasi gender. Penelitian menunjukkan bahwa pesantren tidak selalu menutup dirinya terhadap munculnya kepemimpinan perempuan. Nyai Dadah dengan kemampuannya, mampu mendirikan dan mengelola pesantren putri. Nyai Dadah menjalankan perannya baik sebagai seorang nyai di pesantren atau seorang ibu rumah tangga.

A Model of Job Opportunity Creation through Basic Skill Empowerment for Housewives
Authors: Muslim Azis 
Published: May 2016

Lower economic level of family often encourages the woman contributes to earning living, thus woman plays a double role. Actually, playing a double role as housewife and as living earner is not a serious problem for women. The problem becomes serious when her role is added with children caretaking. The children caretaking job cannot be overridden. For that reason, many women are willing to abandon their role as living earner only for taking care of children. This research aimed to explore a model of creating job opportunity the administrators of PKK (Family Welfare Empowerment) make in their attempt of helping housewives find appropriate job in their house environment, so that housewives can maximize their role and take care of their children all at once. Considering the result of research, it can be found that the job opportunity creation model started with identifying the root of problem the housewives encounter, after which is followed with identifying skill and potential to be utilized, and then formulating the solution. This model, despite simplicity, can be fruitful when it is conducted persistently, thoroughly and smartly. The success is indicated with the increased income of the members.<p> </p>
Assertion Practices and Beliefs Among Nurses and Physicians on an Inpatient Pediatric Medical Unit
Authors: Reese Jennifer , Simmons Ryan , Barnard Juliana 
Published: May 2016

BACKGROUND:
Teamwork and communication are critical elements of safe and effective patient care. Standardized communication tools have been implemented in many health care organizations, but little is known about attitudes and perceptions of assertion, the willingness to “speak up,” by nurses and physicians at an academic pediatric institution.

METHODS:
We conducted 6 focus groups with nurses, residents, and attending physicians using a standardized semistructured focus group guide to promote discussion. Focus groups were recorded and transcribed, and results were analyzed by 2 independent reviewers to identify thematic content.

RESULTS:
Three themes emerged: (1) interpersonal factors, (2) organizational factors, and (3) complexity of care environment. Subthemes were the roles of hierarchy, relationships, and communication and personality style; the value of using standardized communication tools such as SBAR (Situation, Background, Assessment, Recommendation), direct face-to-face communication, and geographic and technology factors; and the need for coordinated communication and agreement across care team members about the care plans. Nurses reported reliance on peers for decision-making, on when and how to assert on behalf of patient care. Nurses and residents experienced barriers to assertion from concerns of relationships and their position within professional hierarchies. Attending physicians were supportive of being asserted to by any care team provider.

CONCLUSIONS:
Interpersonal relationships, power dynamics, and organizational factors impact care team providers’ willingness to assert in the inpatient setting. Standardized communication tools are effective. Further development and implementation of communication models that support experience, peer reliance, and direct face-to-face communication are warranted to improve assertion communication in the inpatient setting.
Emergency and Hospital Care for Food-Related Anaphylaxis in Children
Authors: Parlaman Joshua P. , Oron Assaf P. , Uspal Neil G. , DeJong Katherine N. , Tieder Joel S. 
Published: May 2016

OBJECTIVES:Among patients with food-related anaphylaxis, to describe trends in emergency and hospital care and determine the revisit rate.METHODS:This retrospective cohort study included children 6 months to 18 years of age with food-related anaphylaxis from 37 children’s hospitals between 2007 and 2012. Summary statistics and trends for patient characteristics were evaluated. Multivariable regression was used to identify predictors for hospital admission. Revisit rates to either the emergency department (ED) and/or inpatient unit were calculated.RESULTS:7303 patients were evaluated in the ED; 3652 (50%) were admitted to the hospital. Hospital admission rates varied widely (range, 20%–98%). Food-related anaphylaxis increased from 41 per 100 000 ED visits to 72 per 100 000 while hospital admission rates did not change. Males (odds ratio [OR], 1.2 [95% confidence interval (CI), 1.0–1.4]), patients &lt;1 year old (OR, 1.8 [95% CI, 1.3–2.5]), those with anaphylaxis to either peanut (OR, 1.2 [95% CI, 1.0–1.5]) or tree nut (OR, 1.7 [95% CI, 1.3–2.1]), and patients with asthma (OR, 7.4 [95% CI, 5.8–9.3]) or a chronic complex condition (OR, 5.2 [95% CI, 3.0–9.0]) were more likely to be admitted to the hospital. The 3-day revisit rate was 3% for patients discharged from the ED and 0.6% for those admitted on the index visit.CONCLUSIONS:The incidence of food-related anaphylaxis in pediatric EDs is increasing, but rates of hospital admission are stable. Hospital admission is common but widely variable. Further research is needed to identify optimal management practices for this potentially life-threatening problem.
Nonfatal Playground-Related Traumatic Brain Injuries Among Children, 2001–2013
Authors: Cheng Tabitha A. , Bell Jeneita M. , Haileyesus Tadesse , Gilchrist Julie , Sugerman David E. , Coronado Victor G. 
Published: May 2016

OBJECTIVE:
To describe the circumstances, characteristics, and trends of emergency department (ED) visits for nonfatal, playground-related traumatic brain injury (TBI) among persons aged ≤14 years.

METHODS:
The National Electronic Injury Surveillance System–All Injury Program from January 1, 2001, through December 31, 2013, was examined. US Census bridged-race population estimates were used as the denominator to compute rates per 100 000 population. SAS and Joinpoint linear weighted regression analyses were used to analyze the best-fitting join-point and the annual modeled rate change. These models were used to indicate the magnitude and direction of rate trends for each segment or period.

RESULTS:
During the study period, an annual average of 21 101 persons aged ≤14 years were treated in EDs for playground-related TBI. The ED visit rate for boys was 39.7 per 100 000 and 53.5 for persons aged 5–9 years. Overall, 95.6% were treated and released, 33.5% occurred at places of recreation or sports, and 32.5% occurred at school. Monkey bars or playground gyms (28.3%) and swings (28.1%) were the most frequently associated with TBI, but equipment involvement varied by age group. The annual rate of TBI ED visits increased significantly from 2005 to 2013 (P &lt; .05).

CONCLUSIONS:
Playgrounds remain an important location of injury risk to children. Strategies to reduce the incidence and severity of playground-related TBIs are needed. These may include improved adult supervision, methods to reduce child risk behavior, regular equipment maintenance, and improvements in playground surfaces and environments.
Development of Tropical Lowland Peat Forest Phasic Community Zonations in the Kota Samarahan-Asajaya area, West Sarawak, Malaysia
Authors: Mohamad Mohamad Tarmizi , Fatt Ng Tham , Konjing Zainey , Ashraf Muhammad 
Published: May 2016

<p>Logging observations of auger profiles (Tarmizi, 2014) indicate a vertical, downwards, general decrease of peat humification levels with depth in a tropical lowland peat forest in the Kota Samarahan-Asajaya area in the region of West Sarawak (Malaysia). Based on pollen analyses and field observations, the studied peat profiles can be interpreted as part of a progradation deltaic succession. Continued regression of sea levels, gave rise to the development of peat in a transitional mangrove to floodplain/floodbasin environment, followed by a shallow, topogenic peat depositional environment with riparian influence at approximately 2420 ± 30 years B.P. (until present time). The inferred peat vegetational succession reached Phasic Community I at approximately 2380 ± 30 years B.P. and followed by Phasic Community II at approximately 1780 ± 30 years B.P., towards the upper part of the present, ombrogenic, peat profile. Observations of the presence of large, hollow, Shorea type trees, supports that successive vegetational zonation of the tropical lowland peat dome may have reached Phasic Community II. Some pollen types were found that are also known to occur in the inferred vegetational zonation of Phasic Community III and IV or higher. Pollen analyses indicate that estuarine and deltaic, brackish to saline water influence may have gradually ceased at approximately 0.5 m below the lithological boundary between peat and underlying soil (floodplain deposit) in the tropical lowland peat basin.</p>

Paradoxos do trabalho no capitalismo contemporâneo
Authors: Costa Felizado Tchiengo Bartolomeu , Sterza José Justo , De Freitas Cledione Jacinto 
Published: May 2016

<p>O direito ao trabalho experimentado pela classe trabalhadora se torna problemático quando o mesmo aparece atrelado aos mecanismos de precarização do trabalho decorrentes da lógica capitalista, no qual o mesmo se vê aprisionado pelos artifícios do modo capitalista de produção. Neste artigo, de reflexão teórica, trataremos de demonstrar como a liberdade prometida pelo trabalho na sociedade contemporânea e sua garantia como um direito, por si só, não encerra a questão, da produção de singularização e autonomia dos trabalhadores, pois, além de um meio de sustento ele é também um meio de existência, que se deseja livre dos exercícios de dominação e exploração capitalistas, encobertos por racionalidades tecnológicas. Ou seja, se a garantia de trabalho não vier pautada dentro de uma proposta mais humanizadora para o sujeito trabalhador, então, não poderemos levantar a bandeira da dignidade humana.</p>
