Authors: Diamond Sarah J. , Thomas Charles R. , Desai Sima , Holliday Emma B. , Jagsi Reshma , Schmitt Colleen , Enestvedt Brintha K. 
Published: May 2016

Purpose
Female representation in academic medicine is increasing without proportional increases in female representation at senior ranks. The purpose of this study is to describe the gender representation in academic gastroenterology (GI) and compare publication productivity, academic rank, and career duration between male and female gastroenterologists.

Method
In 2014, the authors collected data including number of publications, career duration, h-index, and m-index for faculty members at 114 U.S. academic GI programs.

Results
Of 2,440 academic faculty, 1,859 (76%) were men and 581 (24%) were women. Half (50%) of men held senior faculty position compared with 29% of women (P < .001). Compared with female faculty, male faculty had significantly (P < .001) longer careers (20 vs. 11 years), more publications (median 24 [0–949] vs. 9 [0–438]), and higher h-indices (8 vs. 4). Higher h-index correlated with higher academic rank (P < .001). The authors detected no difference in the h-index between men and women at the same rank for professor, associate professor, and instructor, nor any difference in the m-index between men and women (0.5 vs. 0.46, respectively, P = .214).

Conclusions
A gender gap exists in the number and proportion of women in academic GI; however, after correcting for career duration, productivity measures that consider quantity and impact are similar for male and female faculty. Women holding senior faculty positions are equally productive as their male counterparts. Early and continued career mentorship will likely lead to continued increases in the rise of women in academic rank.
Symptomatic Treatment for Uncomplicated Acute Diverticulitis: A Prospective Cohort Study
Authors: Mali Juha P. , Mentula Panu J. , Leppäniemi Ari K. , Sallinen Ville J. 
Published: May 2016

BACKGROUND:
Even though evidence for nonantibiotic treatment of uncomplicated diverticulitis exists, it has not gained widespread adoption.

OBJECTIVE:
The aim of this prospective single-arm study was to analyze the safety and efficacy of symptomatic (nonantibiotic) treatment for uncomplicated diverticulitis during a 30-day follow-up period.

DESIGN:
This study is a single-arm prospective trial (ClinicalTrials.gov ID NCT02219698).

SETTINGS:
This study was performed at an academic teaching hospital functioning as both a tertiary and secondary care referral center.

PATIENTS:
Patients, who had CT-verified uncomplicated acute colonic diverticulitis (including diverticulitis with pericolic air), were evaluated for the study. Patients with ongoing antibiotic therapy, immunosuppression, suspicion of peritonitis, organ dysfunction, pregnancy, or other infections requiring antibiotics were excluded.

INTERVENTIONS:
Symptomatic in- or outpatient treatment consisted of mild analgesics (nonsteroidal anti-inflammatory drug or paracetamol).

MAIN OUTCOME MEASURES:
The incidence of complicated diverticulitis was the primary outcome.

RESULTS:
Overall, 161 patients were included in the study, and 153 (95%) completed the 30-day follow-up. Four (3%) of these patients were misdiagnosed (abscess in the initial CT scan). A total of 14 (9%) patients had pericolic air. Altogether, 140 (87%) patients were treated as outpatients, and 4 (3%) of them were admitted to the hospital during the follow-up. None of the patients developed complicated diverticulitis or required surgery, but, 2 days (median) after inclusion, antibiotics were given to 14 (9%, 6 orally, 8 intravenously) patients.

LIMITATIONS:
This study is limited by the lack of a comparison group and by the relatively short follow-up.

CONCLUSIONS:
Symptomatic treatment of uncomplicated diverticulitis without antibiotics is safe and effective.
Comparison of Open, Laparoscopic, and Robotic Colectomies Using a Large National Database: Outcomes and Trends Related to Surgery Center Volume
Authors: Yeo Heather L. , Isaacs Abby J. , Abelson Jonathan S. , Milsom Jeffrey W. , Sedrakyan Art 
Published: May 2016

BACKGROUND:
Previous studies have shown that high-volume centers and laparoscopic techniques improve outcomes of colectomy. These evidence-based measures have been slow to be accepted, and current trends are unknown. In addition, the current rates and outcomes of robotic surgery are unknown.

OBJECTIVE:
The purpose of this study was to examine current national trends in the use of minimally invasive surgery and to evaluate hospital volume trends over time.

DESIGN:
This was a retrospective study.

SETTINGS:
This study was conducted in a tertiary referral hospital.

PATIENTS:
Using the National Inpatient Sample, we evaluated trends in patients undergoing elective open, laparoscopic, and robotic colectomies from 2009 to 2012. Patient and institutional characteristics were evaluated and outcomes compared between groups using multivariate hierarchical-logistic regression and nonparametric tests. The National Inpatient Sample includes patient and hospital demographics, admission and treating diagnoses, inpatient procedures, in-hospital mortality, length of hospital stay, hospital charges, and discharge status.

MAIN OUTCOME MEASURES:
In-hospital mortality and postoperative complications of surgery were measured.

RESULTS:
A total of 509,029 patients underwent elective colectomy from 2009 to 2012. Of those 266,263 (52.3%) were open, 235,080 (46.2%) laparoscopic, and 7686 (1.5%) robotic colectomies. The majority of minimal access surgery is still being performed at high-volume compared with low-volume centers (37.5% vs 28.0% and 44.0% vs 23.0%; p < 0.001). A total of 36% of colectomies were for cancer. The number of robotic colectomies has quadrupled from 702 in 2009 to 3390 (1.1%) in 2012. After adjustment, the rate of iatrogenic complications was higher for robotic surgery (OR = 1.73 (95% CI, 1.20–2.47)), and the median cost of robotic surgery was higher, at $15,649 (interquartile range, $11,840–$20,183) vs $12,071 (interquartile range, $9338–$16,203; p < 0.001 for laparoscopic).

LIMITATIONS:
This study may be limited by selection bias by surgeons regarding the choice of patient management. In addition, there are limitations in the measures of disease severity and, because the database relies on billing codes, there may be inaccuracies such as underreporting.

CONCLUSIONS:
Our results show that the majority of colectomies in the United States are still performed open, although rates of laparoscopy continue to increase. There is a trend toward increased volume of laparoscopic procedures at specialty centers. The role of robotics is still being defined, in light of higher cost, lack of clinical benefit, and increased iatrogenic complications, albeit comparable overall complications, as compared with laparoscopic colectomy.
Integrating Early Intervention for Borderline Personality Disorder and Mood Disorders
Authors: Chanen Andrew M. , Berk Michael , Thompson Katherine 
Published: May 2016

Abstract
Borderline personality disorder (BPD) has been demonstrated to be a reliable and valid construct in young people (adolescents and young adults). Both borderline- and mood-related psychopathology become clinically apparent from puberty through to young adulthood, frequently co-occur, can reinforce one another, and can be difficult to differentiate clinically. This Gordian knot of overlapping clinical features, common risk factors, and precursors to both BPD and mood disorders complicates clinical assessment, prevention, and treatment. Regardless of whether an individual crosses an arbitrary diagnostic threshold, a considerable proportion of young people with borderline- and mood-related psychopathology will develop significant and persistent functional, vocational, and interpersonal impairment and disability during this critical risk and developmental period. There is a clear need for early intervention, but spurious diagnostic certainty risks stigma, misapplication of diagnostic labels, inappropriate treatment, and unfavorable outcomes. This article aims to integrate early intervention for BPD and mood disorders in the clinical context of developmental and phenomenological change and evolution. “Clinical staging,” similar to disease staging in general medicine, is presented as a pragmatic, heuristic, and trans-diagnostic framework to guide prevention and intervention. It acknowledges that the early stages of these disorders cannot be disentangled sufficiently to allow for disorder-specific preventive measures and early interventions. Clinical staging defines an individual’s location along the continuum of the evolving temporal course of a disorder. Such staging aids differentiation of early or milder clinical phenomena from those that accompany illness progression and chronicity, and suggests the application of appropriate and proportionate intervention strategies.

Published: May 2016

SUMMARYAdvances in mass spectrometry have made the quantitative measurement of proteins across multiple samples a reality, allowing for the study of complex biological systems such as the metabolic syndrome. Although deregulation of lipid metabolism and increased hepatic storage of triacylglycerides are known to play a part in the onset of the metabolic syndrome, its molecular basis and dependency on dietary and genotypic factors are poorly characterized. Here, we used a rich experimental design with two different mouse strains, dietary and metabolic perturbations to generate a compendium of quantitative proteome data, using three mass spectrometry strategies. The data recapitulates known properties of the metabolic system and indicate differential molecular adaptation of the two mouse strains to perturbations, contributing to a better understanding of the metabolic syndrome. We show that high-quality, high-throughput proteomic datasets provide an unbiased broad overview of complex systems upon perturbation.HIGHLIGHTSRich experimental design with two mouse strains, dietary and metabolic perturbationsThree mass spectrometry proteomic data collection strategies in one data compendiumSWATH-MS data with systematic perturbation provide a broad unbiased view of the systemThe data reveals differential adaptation of molecular systems in two mouse strains
trio-sga: facilitatingde novoassembly of highly heterozygous genomes with parent-child trios
Authors: Malinsky Milan , Simpson Jared T. , Durbin Richard 
Published: May 2016

AbstractMotivationMost DNA sequence in diploid organisms is found in two copies, one contributed by the mother and the other by the father. The high density of differences between the maternally and paternally contributed sequences (heterozygous sites) in some organisms makesde novogenome assembly very challenging, even for algorithms specifically designed to deal with these cases. Therefore, various approaches, most commonly inbreeding in the laboratory, are used to reduce heterozygosity in genomic data prior to assembly. However, many species are not amenable to these techniques.ResultsWe introducetrio-sga, a set of three algorithms designed to take advantage of mother-father-offspring trio sequencing to facilitate better quality genome assembly in organisms with moderate to high levels of heterozygosity. Two of the algorithms use haplotype phase information present in the trio data to eliminate the majority of heterozygous sites before the assembly commences. The third algorithm is designed to reduce sequencing costs by enabling the use of parents’ reads in the assembly of the genome of the offspring. We test these algorithms on a ‘simulated trio’ from four hap-loid datasets, and further demonstrate their performance by assembling three highly heterozygousHeliconiusbutterfly genomes. While the implementation oftrio-sgais tuned towards Illumina-generated data, we note that the trio approach to reducing heterozygosity is likely to have cross-platform utility forde novoassembly.
An optimal sequential information acquisition model subject to a heuristic assimilation constraint
Authors: Di Caprio Debora , Santos-Arteaga Francisco J. , Tavana Madjid 
Published: May 2016

Purpose
– The purpose of this paper is to study the optimal sequential information acquisition process of a rational decision maker (DM) when allowed to acquire n pieces of information from a set of bi-dimensional products whose characteristics vary in a continuum set.

Design/methodology/approach
– The authors incorporate a heuristic mechanism that makes the n-observation scenario faced by a DM tractable. This heuristic allows the DM to assimilate substantial amounts of information and define an acquisition strategy within a coherent analytical framework. Numerical simulations are introduced to illustrate the main results obtained.

Findings
– The information acquisition behavior modeled in this paper corresponds to that of a perfectly rational DM, i.e. endowed with complete and transitive preferences, whose objective is to choose optimally among the products available subject to a heuristic assimilation constraint. The current paper opens the way for additional research on heuristic information acquisition and choice processes when considered from a satisficing perspective that accounts for cognitive limits in the information processing capacities of DMs.

Originality/value
– The proposed information acquisition algorithm does not allow for the use of standard dynamic programming techniques. That is, after each observation is gathered, a rational DM must modify his information acquisition strategy and recalculate his or her expected payoffs in terms of the observations already acquired and the information still to be gathered.
Supplier/partner selection in agile supply chain
Authors: Matawale Chhabi Ram , Datta Saurav , Mahapatra S.S. 
Published: May 2016

Purpose
– The concept of agile supply chain (ASC) has become increasingly important as means of achieving a competitive edge in turbulent business environments. An ASC is a dynamic alliance of member enterprises, the adaptation of which is likely to introduce velocity, responsiveness and flexibility into the manufacturing system. In ASC management, supplier/partner selection is a key strategic concern; influenced by various agility-related criteria/attributes. Therefore, evaluation and selection of potential supplier in an ASC has become an important multi-criteria decision-making problem. The purpose of this paper is to report, a supplier selection procedure (module) in the context of ASC.

Design/methodology/approach
– During supplier selection, subjectivity of evaluation information (human judgment) often creates conflict and bears some kind of uncertainty. To overcome this, the present work attempts to explore vague set theory to deal with uncertainties in the supplier selection decision-making process. Since, vague sets can provide more accurate information as compared to fuzzy sets. It considers true membership function as well as false membership function which give more superior results for uncertain information. In this procedure, first, linguistic variables have been used to assess appropriateness rating (performance extent) as well as priority weights for individual quantitative or qualitative criterions. Second, the concept of degree of similarity and probability of vague sets has been used to determine appropriate ranking order of the potential supplier alternatives.

Findings
– A case empirical example has been provided. It has been proved that the methodology would be fruitful in considering different evaluation criterion (indices); may be contradicting in nature like beneficial and cost criterions. The application of vague set theory has also been proved as a better option to work under uncertain (fuzzy) decision-making environment in comparison to fuzzy set theory.

Originality/value
– The application of vague set theory in multi-criteria group decision making has been reported in literature to a limited extent. Application of vague set as a decision-making tool in agile supplier selection appears relative new and unexplored work area. The work has got remarkable managerial implications.
Strategic benchmarking of service pricing based on the value added
Authors: Trento Carlos Renato , Stüker Timóteo , Pereira Giancarlo Medeiros , Borchardt Miriam , Viegas Cláudia V. 
Published: May 2016

Purpose– The purpose of this paper is to investigate opportunities to move benchmarking studies toward a strategic level. The authors benchmarked how service prices are defined based on the value added for the customer.Design/methodology/approach– A multi-case research investigated how manufacturers can increase their service revenues; how corporate reputation can be analyzed to enhance financial and market performance; how customer satisfaction and price acceptance are related; and how benchmark studies can move to a more strategic level based on a conjoint analysis of value and price.Findings– Price’s benchmarking studies must combine the customers’ value demands; the customer expectations associated to each value demand; the competitor prices; and the revenue alternatives that a supplier can explore (e.g. sale of new goods, services for new goods, services for non-new goods, and repair parts). The combination of these elements reveals several opportunities for revenue generation. This combination may also help to explain the existence of different prices for similar goods and services. The authors referred to this as a flexible pricing policy. Flexible pricing may help manufacturers maximize revenues, and win and maintain customers.Research limitations/implications– The following research questions are suggested for future studies: What other elements should be considered in strategic benchmarking studies? What other elements can influence a flexible pricing policy for goods, spare parts, and services? In what contexts can a flexible pricing policy be applied? How should flexible pricing practices be benchmarked?Practical implications– A strategic benchmarking study must first identify the customers’ value demands. It is then necessary to analyze customer expectations associated to each value demand. As shown, customers may have different expectations for the same product or service. Similar expectations must be grouped together in order to allow a well-structured benchmark.Originality/value– The authors’ findings suggest interesting points to be observed by the manufacturers who supply integrated solutions with a long life cycle.
Micro drilling quality of the Cu/BT laminate for IC substrate
Authors: Li Shan , Zheng Li Juan , Wang Cheng Yong , Liao Bing Miao , Fu Lianyu 
Published: May 2016

Purpose
In an integrated circuit (IC) substrate, more fillers, including talcum powder and aluminium hydroxide, are added, which leads to much higher rigidity and hardness compared with a traditional printed circuit board. However, the micro drilling of IC substrates is harder. This paper aims to test the drilling process of IC substrates to improve the drilling process and the micro hole quality.

Design/methodology/approach
Substrate drilling by a micro drill with 0.11-mm diameter was used under several drilling conditions. The influence of drilling conditions on the drilling process was observed. Drilling forces, drill wear and micro hole quality were also studied.

Findings
The deformation circle around holes, hole location accuracy, bugle hole and burrs were the major defects of micro holes that were observed during the drilling of the substrate. Reducing the drilling force and drill wear was the effective way to improve hole quality.

Originality/value
The technology and manufacturing of IC substrates has been little investigated. Research data on drilling IC substrates is lacking. The micro hole quality directly affects the reliability of IC substrates. Thus, improving the drilling technology of IC substrates is very important.
The influencing mechanism of drilling parameters on micro drilling temperature on the basis of calibration of surface emissivity of micro drill bit
Authors: Shi Hongyan , Ning Jiali , Yan Qiuxin 
Published: May 2016

Purpose
The purpose of this paper is to calibrate the surface emissivity of micro drill bit and to investigate the effect of different drilling parameters on the temperature of micro drill bit in printed circuit board (PCB) micro drilling process.

Design/methodology/approach
The surface emissivity of micro drill bit was obtained by experiments. Analysis of variance (ANOVA) was applied in this study to analysis the effect of different drilling parameters on the temperature of micro drill bit in PCB micro hole drilling. The most significant influencing factor on micro drill bit temperature was achieved by ANOVA.

Findings
First, the surface emissivity of cemented carbide rod decreased from 0.4 to 0.32 slowly with temperature in the range of 50-220°C. Second, the most significant influencing factor on the micro drill bit temperature was spindle speed among the drilling parameters including spindle speed, retract rate and infeed rate.

Research limitations/implications
In this paper, the influence of roughness of black coating, carbide rod and micro drill bit on the surface emissivity calibration and the temperature measurement was not considered.

Originality/value
A new simple method has been presented to calibrate the surface emissivity of micro drill bit. Through calibrating the surface emissivity of micro drill bit, the temperature of micro drill bit can be measured accurately by infrared thermometry. Analyzing the influences of different drilling parameters on the temperature of micro drill bit, the mechanism of drilling parameters on drilling temperature is achieved. The basis for the selection of drilling parameters to improve the hole quality is enhanced.
Passive device embedded substrate for application of RF module
Authors: Kim Hyunho 
Published: May 2016

Purpose
The purpose of this study is to form fabrication and electrical characteristics of passive device embedded substrate that is embedded chip bead inductor and chip capacitor inside substrate for the application of radio frequency (RF) modules.

Design/methodology/approach
Passive device embedded substrate was fabricated using embedding process that consists of lamination process, laser drilling at the electrode Cu pads of passive components, electro-less Cu plating formation process such as photolithography, electrolytic Cu plating and etching. Impedance and capacitance characteristics of the fabricated passive device embedded substrate were evaluated.

Findings
By checking what embedded components are placed in the appropriate place using failure analysis via connection performance between copper plane and embedded components was verified. For measuring electrical characteristics of the fabricated passive device embedded substrate, the evaluation was done using test methods like continuity test for checking interconnections which are not connected to any embedded components and in-circuit test for checking interconnections which are connected to any embedded component. From in-circuit testing for embedding passive components with series and parallel circuits, the authors verified how to test passive device embedded substrate by using capacitance and impedance measurement with the comparison of measured results between good samples and bad samples.

Originality/value
Ultra miniaturized and low-profile mobile products are driving the need for embedded passive component integration technologies using a novel manufacturing-compatible organic substrate and interconnect technologies. Fabrication and test methods for passive device embedded substrate described in this paper are expected to lead to be developed to make quality measurable for the application of RF modules.
