Prior Delinquency and Depression Differentially Predict Conditional Associations between Discrete Patterns of Adolescent Religiosity and Adult Alcohol Use Patterns
Authors: Hoyland Meredith A , Rowatt Wade C , Latendresse Shawn J
Published: March 2017

Prior research has demonstrated that adolescent delinquency and depression are prospectively related to adult alcohol use and that adolescent religiosity may influence these relationships. However, such associations have not been investigated using person-centered approaches that provide nuanced explorations of these constructs. Using data from the National Longitudinal Study of Adolescent to Adult Health, we examined whether adolescent delinquency and depression differentiated typologies of adult alcohol users and whether these relationships varied across religiosity profiles. Three typologies of self-identified Christian adolescents and 4 types of adult alcohol users were identified via latent profile analysis. Delinquency and depression were related to increased likelihood of membership in heavy drinking or problematic alcohol use profiles, but this relationship was most evident among those likely to be involved in religious practices. These results demonstrate the importance of person-centered approaches in characterizing the influences of internalizing and externalizing behaviors on subsequent patterns of alcohol use.
Cardiac Evaluation and Monitoring of Patients Undergoing Noncardiac Surgery
Authors: Rafiq Arsalan , Sklyar Eduard , Bella Jonathan N
Published: March 2017

Surgical management of disease has a tremendous impact on our health system. Millions of people worldwide undergo surgeries every year. Cardiovascular complications in the perioperative period are one of the most common events leading to increased morbidity and mortality. Although such events are very small in number, they are associated with a high mortality rate making it essential for physicians to understand the importance of perioperative cardiovascular risk assessment and evaluation. Its involves a detailed process of history taking, patient's medical profile, medications being used, functional status of the patient, and knowledge about the surgical procedure and its inherent risks. Different risk assessment tools and calculators have also been developed to aid in this process, each with their own advantages and limitations. After such a comprehensive evaluation, a physician will be able to provide a risk assessment or it may all lead to further testing if it is believed that a change in management after such testing will help to reduce perioperative morbidity and mortality. There is extensive literature on the significance of multiple perioperative testing modalities and how they can change management. The purpose of our review is to provide a concise but comprehensive analysis on all such aspects of perioperative cardiovascular risk assessment for noncardiac surgeries and provide a basic methodology toward such assessment and decision making.

Authors: Madabhavi Irappa , Patel Apurva , Sarkar Malay , Anand Asha , Panchal Harsha , Parikh Sonia
Published: March 2017

Background:

Effective and reliable venous access is one of the cornerstones of modern medical therapy in oncology.

Materials and methods:

This is a prospective observational study, which collected data of patients who require “PORT” catheter insertion for any cancer, at a tertiary care oncology hospital in Ahmadabad, Gujarat, India, during a 2-year period.

Aims and objectives:

The main objective of this study was to study the various complications and outcomes related to “PORT” catheters.

Results:

“PORT” catheter was inserted in 100 patients and was most commonly used in solid malignancies (n = 86, 86%), followed by hematologic malignancies (n = 14, 14%). Among the solid malignancies, breast cancer (38, 38%) was the most common underlying disease, whereas among the hematologic malignancies, acute lymphoblastic leukemia (6, 6%) was the most common underlying disease for “PORT” catheter insertion. Chemotherapy was started on the first day of “PORT” catheter in 74% of patients in the “PORT” study group. The various complications developed in the “PORT” study group in the descending order are as follows: 4 patients (4%) developed early infection (⩽30 days after “PORT” placement), 4 (4%) late infection (⩾30 days after “PORT” placement), 4 (4%) bloodstream infection, 2 (2%) local skin infection at the “PORT” insertion site, 2 (2%) dislodgment of the “PORT” catheter, 2 (2%) fracture of the “PORT” catheter, and 1 recurrent pleural effusion. One patient (1%) developed thrombosis as the complication of “PORT” catheter insertion.

Conclusions:

The most disturbing aspect of treatment for a patient with cancer is multiple painful venipunctures made for administration of cytotoxic agents, antibiotics, blood products, and nutritional supplements. The focus of this prospective observational research is to study the various underlying diseases for which “PORT” catheter is needed in different solid and hematologic malignancies and the various complications and outcomes in pediatric and adult patients with cancer.
Primary Melanotic Paraganglioma of Thyroid Gland: Report of a Rare Case With Clinicopathologic and Immunohistochemical Analysis and a Literature Review
Authors: Dong Yan-jun , Zhang Zhi-wen , Wang Zhen , Wang Xin-ying , Tian Zhi-zhen , Zhang Xiang-sheng
Published: March 2017

Background:

Pigmented paraganglioma is a special type of paraganglioma, and it is rare in the thyroid.

Case Presentation:

We report a case of a 41-year-old woman who had complained of a mass in the thyroid gland. Histology revealed tumor cells arranged in a nest-like or organoid pattern, separated by delicate fibrovascular septa. Two distinct components were observed. In the first, which constituted the majority of the tumor cells, no pigments were observed. In the second, a few cells with pigment showed intercellular substance, but the structure was unclear. Using immunohistochemistry, cells in the first component were confirmed to be diffuse strong positive for synaptophysin, but negative for chromogranin A, pan-cytokeratin, calcitonin, and thyroglobulin. About 1% of tumor cells were stained by Ki-67. In the margins of the tumor, a few cells were observed to be positive for HMB-45 and Melan A after bleaching by oxalic acid. The stromal cells were positive for S-100. Using electron microscopy, a few cells containing many round melanin bodies with greater electron density granules of nonuniform size were observed. The diagnosis of primary melanotic paraganglioma of the thyroid gland was made.

Conclusion:

Primary melanotic paraganglioma of the thyroid gland is a rare, low malignant potential tumor. To the best of our knowledge, this is the first case described.
Relationship Between Exclusive Breastfeeding and Lower Risk of Childhood Obesity: A Narrative Review of Published Evidence
Authors: Uwaezuoke Samuel N , Eneh Chizoma I , Ndu Ikenna K
Published: March 2017

Background:

The pattern of infant feeding during the first 1000-day period—from conception to the second birthday—has a significant influence on the child’s growth trajectory. The relationship between exclusive breastfeeding and lower risk of childhood obesity has elicited much scientific interest, given the fact that this form of malnutrition is becoming a global epidemic.

Aim:

This narrative review aims to examine the evidence in the literature linking exclusive breastfeeding with reduction in obesity in children.

Literature search:

Using appropriate search terms, PubMed database was searched for relevant articles that met the review objective.

Results:

Evidence for the protective effect of exclusive breastfeeding against childhood obesity have been provided by studies which explored 5 physiologic mechanisms and those that established the causality between breastfeeding and lower risk of obesity. The few studies that disputed this relationship highlighted the influence of confounding factors. A new insight on molecular mechanisms, however, points to a direct and indirect effect of human milk oligosaccharides on the prevention of overweight and obesity.

Conclusions:

The preponderance of current evidence strongly suggests that exclusivity in breastfeeding can prevent the development of obesity in children.
The Need for Antiepileptic Drug Chronotherapy to Treat Selected Childhood Epilepsy Syndromes and Avert the Harmful Consequences of Drug Resistance
Authors: Manganaro Sheryl , Loddenkemper Tobias , Rotenberg Alexander
Published: March 2017

Antiepileptic drug (AED) chronotherapy involves the delivery of a greater AED dose at the time of greatest seizure susceptibility usually associated with predictable seizure peaks. Although research has proven AED chronotherapy, commonly known as differential dosing, to be safe, well tolerated, and highly effective in managing cyclic seizure patterns in selected childhood epilepsies, conventional, equally divided AED dosing remains the standard of care. Differential dosing is more often applied in the emergency management of acute seizure clustering resulting from drug resistance—a harmful epilepsy-related consequence that affects 30% of children. Moreover, drug resistance is a major risk factor in status epilepticus and sudden, unexpected death in epilepsy. Although these facts should promote the wider use of differential dosing in selected cases, a credible hypothesis is needed that defines the differential dosing strategy and application in cyclic epilepsy and for the greater purpose of preventing harmful outcomes.
Modalities of opposition: Control and resistance via visual materiality
Authors: Alcadipani Rafael , Islam Gazi
Published: March 2017

This article examines how the material, and specifically visual, aspects of organizing contribute to understanding control and resistance issues in organizations. Whereas the role of visuality in workplace power relations has been acknowledged, the processes by which specific visual affordances contribute to power contests are not well understood. We argue that the diverse affordances of visual images offer opportunities for both control and resistance, where control is exerted via the normalizing and objectifying feature of visuality, while resistance draws on bricolage and juxtaposition to subvert dominant management discourses. Based on an ethnographic study of an industrial print company, we show how the diverse uses of visuality create a field for negotiating organizational tensions. We draw conclusions for the study of visual affordances as a tool for control and resistance struggles in organizations.
Body dissatisfaction and eating disorder symptomatology: Which factors interfere with sexuality in women with eating disorders?
Authors: Tolosa-Sola Iris , Gunnard Katarina , Giménez Muniesa Cristina , Casals Laura , Grau Antoni , Farré Josep Maria
Published: March 2017

Body dissatisfaction is a relevant aspect in both eating disorders and sexuality. Using Stice’s model, this study aimed to evaluate the relationship between these variables in eating disorder patients compared with healthy controls. Statistically significant correlations between body dissatisfaction and sexuality were found in the whole sample. The clinical group had higher rates of body dissatisfaction and sexual impairment. Within the clinical group, the participants with a greater drive for thinness showed higher sexual dysfunctions. These results suggest that sexuality should be systematically explored in eating disorders. Higher rates of drive for thinness may be associated with greater sexual impairment.
Investigation of the longitudinal wind power spectra at the gorge terrain
Authors: Hu Peng , Li Yongle , Xu GJ , Han Yan , Cai CS , Xue Fanrong
Published: March 2017

This study investigates the fundamental characteristics of the longitudinal wind power spectra at the gorge terrain. First, a simplified V-shaped gorge terrain model, representing usual deep-cutting gorge terrains where long-span bridges usually straddle, was introduced for the wind tunnel test. The longitudinal wind power spectra at the gorge center were analyzed in detail and compared with those of the simulated oncoming wind. Then, a practical calculation method was proposed to directly calculate the power spectra values at the gorge terrain based on the oncoming wind field and minimum wind parameters at the gorge center. Finally, an infield V-shaped deep-cutting gorge terrain model was also introduced for the wind tunnel test, and the obtained wind power spectra further validated the proposed calculation method. The results show that for both gorge terrain models, the power spectra values in the low-frequency range become closer to those of the oncoming wind with the measurement positions moving away from the ground, while good agreements are always found in the high-frequency range for all of the specified measurement positions. The proposed calculation method can calculate the power spectra values at these two gorge terrains with relatively high accuracy. It is hoped that this study can more conveniently provide informative guidelines for determining the wind power spectra values for similar gorge terrains in engineering practices than traditional wind tunnel tests or computational fluid dynamics numerical simulations.
Governing Sustainable Forest Management Issues in Polycentric Governance
Authors: Dlamini Cliff , Montouroy Yves
Published: March 2017

This article provides the overall view of the international regulatory context for good forest governance (GFG) and sustainable forest management (SFM). It starts by giving a brief overview of the international forestry regime, trade agreements, the Rio conventions, and forestry principles. Subsequently, the Food and Agriculture Organization of the United Nations (FAO) tools for forest assessment and the World Bank Forestry Strategy are discussed. Further, timelines for various regional and international Criteria and Indicators (C&I) for SFM and trade in forest products are highlighted. Finally the leading international voluntary programmes for forest certification are described. From this review, it is clear there is a gap in the international forestry regime, there is an urgent need for an international legally binding forest convention which will guide Forest Law Enforcement, Governance and Trade (FLEGT) programmes at the local, national, regional and international/global scale. Here, we argue that FLEGT can catalyse these fragmented elements of an international regime as the EU FLEGT action plan provides a framework to catalyse all dedicated and cross-cutting issue instruments in national forest policy.
Brexit and the devolution dynamics
Authors: Reid Colin T.
Published: March 2017

Brexit will mean the return of powers from Brussels not just to London but to a devolved United Kingdom, with environmental matters primarily a responsibility of the devolved administrations. This will require careful attention to how and where law can be made. The devolved authorities could go their own way on many issues but the need to comply with international obligations will provide a continuing constraint, and a source of tension since all aspects of international relations remain in the hands of the UK authorities. There are strong reasons for continuing cooperation and coordination across the UK, and with the EU, but mechanisms to achieve this must be found. Differing ambitions for the post-Brexit position may have consequences for devolution itself, with the Scottish Government calling for powers in some non-devolved areas currently dominated by EU law to be passed away from London and for a stronger role in international affairs.
Leveraging Research to Advance Undergraduate HRD Education: An Introduction
Authors: Greer Tomika W. , Collins Joshua C.
Published: March 2017

The Problem

As undergraduate human resource development (HRD) programs continue to develop in the United States, faculty face challenges related to finding tools, resources, and curriculum to effectively teach the principles and practices of the field to traditional college students. Most of the existing research regarding academic programs in HRD is based on graduate programs and is, therefore, less attentive to the potential of undergraduate programs as a viable pathway to the HRD profession. Little scholarship exists to address this important, pressing, and timely issue.

The Solution

This issue of Advances in Developing Human Resources addresses the gap in knowledge regarding better practices for teaching and learning in undergraduate HRD programs and contains the first collection of focused examinations of HRD undergraduate students, programs, and experiences. This collection of articles gives direction for building undergraduate HRD curricula and enhancing its relevance for traditional college students, identifies relevant competencies for undergraduate HRD programs, and provides insight into alumni perspectives of the value of an undergraduate degree in HRD.

The Stakeholders

The primary audience is HRD faculty, scholars, and scholar-practitioners who engage with undergraduate students or hope to in the future. Secondary audiences include human resource management (HRM), management, adult educators, higher education administrators, career counselors, and other professionals who are involved with enhancing the extent to which undergraduate students and new graduates are equipped to make meaningful contributions to organizations.
Homeland Integration
Authors: Ai Bin , Wang Lifei
Published: March 2017

In this study, the first author narrates his experiences of the challenges of integration into several Chinese universities as a PhD graduate after returning from Australia. His patterns of communication and psychological changes are examined in terms of identity construction and transformation. His insider position as a Chinese native and academic returnee enables him to see the realities of practice in average Chinese universities at close range, yet with the altered vision gained from his overseas experience. This study highlights the challenges for academic returnees in Chinese higher education institutions and may also have resonances for academic returnees in other countries. Wider questions about the assessment of English research writing and the attitudes to academic returnees in Chinese universities are raised, contributing to debate over the future development of Chinese higher education institutions in a globalizing world.
Frequency of hypertension in hospitalized population with osteoporotic fractures: Epidemiological retrospective analysis of Hospital Discharge Data in the Apulian database for the period 2006–2010
Authors: Notarnicola Angela , Tafuri Silvio , Maccagnano Giuseppe , Moretti Lorenzo , Moretti Biagio
Published: March 2017

Osteoporosis and hypertension are two widespread diseases, which share many of the same risk factors such as advanced age, early menopause, smoking, and physical inactivity. The aim of this study is to examine the association between fragility fractures, anti-hypertensive drugs (subgroup C02, according to the Anatomical Therapeutic Chemical classification system [ATC]), diuretics (subgroup C03), b-blocker (subgroup C07), calcium antagonist (subgroup C08) and renin-angiotensin-aldosterone system regulator (subC09), and drugs administration for osteoporosis among the osteoporotic population of a region of Southern Italy.

We retrospectively studied “Hospital Discharge Data” (HDD) in the Apulian database for the period 2006–2010 to find fragility fractures treated with hospitalization in men aged over 65 years and in women aged over 50 years. We then checked the database for drug prescriptions to identify those patients who had taken at least one osteoporosis drug. Within this latter group, based on hospital admissions and prescription records, we identified the patients affected with hypertension.

We observed that, between 2006 and 2010, in Apulia, 177,639 patients were hospitalized and diagnosed as having fragility fractures. The prevalence of hypertension patients in Apulia in this period was estimated at 44.3%. In the same region and period, the prevalence of patients with fragility fracture, who also had hypertension, was 80.9%. The percentage of fracture was lowest in the female population aged 50–59 years (52.5%), while the highest was in women aged > 80 years (92.5%). We observed that in hypertensive patients the most frequent site of fracture was the femur (43,638 cases), while the least frequent were the tarsus and metatarsus (742 cases combined). The patients who took angiotensin-converting enzyme (ACE) inhibitor and diuretic drugs presented a higher number of fragility fractures, while the calcium antagonists, beta-blockers, and ATC anti-hypertensive drugs were linked to a reduced incidence of lesions.

Hypertension is associated with increased fracture risk in the Apulia population. The bone demineralization effect of this disease should be taken into account during the management of these patients. The different distribution of fragility fractures in relation to anti-hypertensive treatment warrants further investigation.

A genosonic analysis of ISIL and US counter-extremism video messages
Authors: Bean Hamilton , Edgar Amanda Nell
Published: March 2017

Analyses of extremist video messages typically focus on their discursive content. Using the case of ISIL (Islamic State of Iraq and the Levant), this study instead draws upon the emerging subfield of genosonic analysis to understand the allure of extremist videos, as well as the ineffectiveness of US video messages designed to ‘counter violent extremism’ (CVE). Through a genosonic analysis of three high-profile ISIL videos and five popular US State Department CVE videos, the study advances two concepts – sonorous communality and sonic unmaking – to help explain ISIL’s appeal. The lack of equivalent dimensions in US CVE videos renders them sonically sterile in comparison to those of ISIL. The implications of this analysis for scholarship and practice conducted at the intersection of media, war and conflict are discussed.
Diagnostic accuracy of single-compartment magnetic resonance arthrography in detecting common causes of chronic wrist pain
Authors: Asaad A. M. , Andronic A. , Newby M. P. , Harrison J. W. K.
Published: March 2017

We reviewed a series of 50 consecutive wrist arthroscopy patients who had been investigated pre-operatively by direct magnetic resonance arthrography and calculated the sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy of magnetic resonance arthrography in detecting full-thickness triangular fibrocartilage complex tears, intrinsic carpal ligamentous lesions, wrist synovitis and chondral lesions in the radiocarpal joint. The sensitivities of magnetic resonance arthrography in detecting central triangular fibrocartilage complex tears, peripheral triangular fibrocartilage complex tears, scapholunate ligament tears, lunotriquetral ligament tears, dorsal synovitis and radiocarpal chondral lesions were 89%, 63%, 71%, 100%, 32% and 65%, respectively, and its specificities in detecting these lesions were 91%, 98%, 89%, 94% 94% and 97%, respectively. This study suggests that single compartment direct wrist magnetic resonance arthrography can provide high diagnostic accuracy for full-thickness triangular fibrocartilage lesions, intrinsic carpal ligament tears and chondral lesions in the radiocarpal joint, but that it is much less accurate in diagnosing synovitis of the radiocarpal joint.

Gender differences in gratifications from fitness app use and implications for health interventions
Authors: Klenk Saskia , Reifegerste Doreen , Renatus Rebecca
Published: March 2017

Previous research has shown gender differences in the motivations to be physically active, in mobile phone gratifications, and social media usage, but so far these areas have not been studied together. Based on the uses and gratification approach and self-determination theory, we aimed to identify gender-specific gratifications and determinants of fitness app usage in combination with fitness-related Facebook groups. Results of an online survey ( N = 171) and of a mobile experience sampling method ( N = 31) revealed that the app Runtastic was primarily used for achieving goals and to improve enjoyment for physical activity, with men and older participants sharing results with others in Facebook groups more often than women and younger participants. Conclusions regarding gender-specific targeting strategies and user-centered design and content of mHealth features are presented.
The career prospects of overeducated Americans
Authors: Clark Brian , Joubert Clément , Maurel Arnaud
Published: March 2017

In this paper we analyze career dynamics for US workers who have more schooling than their peers in the same occupation. We use data from the NLSY79 combined with the CPS to analyze transitions into and out of overeducated employment, together with the corresponding effects on wages. Overeducation is a fairly persistent phenomenon at the aggregate and individual levels, with 66% of workers remaining overeducated after 1 year. Overeducation is not just more common but also more persistent among blacks and low-AFQT individuals. Further, the hazard rate out of overeducation drops by about 60% during the first 5 years spent overeducated. However, the estimation of a mixed proportional hazard model suggests that this is attributable to selection on unobservables rather than true duration dependence. Lastly, overeducation is associated with lower current as well as future wages, consistent with scarring effects.
Imaging near-surface heterogeneities by natural migration of backscattered surface waves: Field data test
Authors: Liu Zhaolun , AlTheyab Abdullah , Hanafy Sherif M. , Schuster Gerard
Published: March 2017

We have developed a methodology for detecting the presence of near-surface heterogeneities by naturally migrating backscattered surface waves in controlled-source data. The near-surface heterogeneities must be located within a depth of approximately one-third the dominant wavelength [Formula: see text] of the strong surface-wave arrivals. This natural migration method does not require knowledge of the near-surface phase-velocity distribution because it uses the recorded data to approximate the Green’s functions for migration. Prior to migration, the backscattered data are separated from the original records, and the band-passed filtered data are migrated to give an estimate of the migration image at a depth of approximately one-third [Formula: see text]. Each band-passed data set gives a migration image at a different depth. Results with synthetic data and field data recorded over known faults validate the effectiveness of this method. Migrating the surface waves in recorded 2D and 3D data sets accurately reveals the locations of known faults. The limitation of this method is that it requires a dense array of receivers with a geophone interval less than approximately one-half [Formula: see text].
Building 3D subsurface models conforming to seismic structural and stratigraphic features
Authors: Wu Xinming
Published: March 2017

Subsurface modeling from seismic and borehole data is important for reservoir prediction, geophysical exploration, and production. A reasonable model should honor borehole rock properties and conform to seismic structural and stratigraphic features. Such a subsurface model can be difficult to build in cases complicated by faults and unconformities. Automatic and semiautomatic methods have been proposed to build subsurface models from seismic and borehole data; however, seismic structural and stratigraphic features and borehole measurements are not fully used in most methods. I have developed a workflow to fully use seismic and borehole data to build subsurface models that honor borehole measurements and conform to seismic horizons, faults, unconformities, and stratigraphic features such as channels. In this workflow, I first automatically remove the faulting and folding in seismic and borehole data and map them into an unfaulted and flattened space, in which seismic reflectors and borehole measurements corresponding to the same geologic layers are horizontally aligned. I then build a subsurface model in this unfaulted and flattened space by computing a sequence of 2D horizontal interpolations of borehole data. Each horizontal interpolation is guided by the stratigraphic features apparent in the corresponding horizontal seismic slice, so that the interpolant conforms to the seismic stratigraphic features. I finally map the interpolated model back into the input space and obtain a subsurface model that honors the seismic and borehole data. I demonstrate the proposed workflow using synthetic and real examples complicated by faults and unconformities.
Methodological advances in imaging intravital axonal transport
Authors: Sleigh James N. , Vagnoni Alessio , Twelvetrees Alison E. , Schiavo Giampietro
Published: March 2017

Axonal transport is the active process whereby neurons transport cargoes such as organelles and proteins anterogradely from the cell body to the axon terminal and retrogradely in the opposite direction. Bi-directional transport in axons is absolutely essential for the functioning and survival of neurons and appears to be negatively impacted by both aging and diseases of the nervous system, such as Alzheimer’s disease and amyotrophic lateral sclerosis. The movement of individual cargoes along axons has been studied in vitro in live neurons and tissue explants for a number of years; however, it is currently unclear as to whether these systems faithfully and consistently replicate the in vivo situation. A number of intravital techniques originally developed for studying diverse biological events have recently been adapted to monitor axonal transport in real-time in a range of live organisms and are providing novel insight into this dynamic process. Here, we highlight these methodological advances in intravital imaging of axonal transport, outlining key strengths and limitations while discussing findings, possible improvements, and outstanding questions.
Effect of citrus-based products on urine profile: A systematic review and meta-analysis
Authors: Rahman Fakhri , Birowo Ponco , Widyahening Indah S. , Rasyid Nur
Published: March 2017

Background. Urolithiasis is a disease with high recurrence rate, 30-50% within 5 years. The aim of the present study was to learn the effects of citrus-based products on the urine profile in healthy persons and people with urolithiasis compared to control diet and potassium citrate. Methods. A systematic review was performed, which included interventional, prospective observational and retrospective studies, comparing citrus-based therapy with standard diet therapy, mineral water, or potassium citrate. A literature search was conducted using PUBMED, COCHRANE, and Google Scholar with “citrus or lemonade or orange or grapefruit or lime or juice” and “urolithiasis” as search terms. For statistical analysis, a fixed-effects model was conducted when p > 0.05, and random-effects model was conducted when p < 0.05. Results. In total, 135 citations were found through database searching with 10 studies found to be consistent with our selection criteria. However, only 8 studies were included in quantitative analysis, due to data availability. The present study showed a higher increased in urine pH for citrus-based products (mean difference, 0.16; 95% CI 0.01-0.32) and urinary citrate (mean difference, 124.49; 95% CI 80.24-168.74) compared with a control group. However, no differences were found in urine volume, urinary calcium, urinary oxalate, and urinary uric acid. From subgroup analysis, we found that citrus-based products consistently increased urinary citrate level higher than controls in both healthy and urolithiasis populations. Furthermore, there was lower urinary calcium level among people with urolithiasis. Conclusions. Citrus-based products could increase urinary citrate level significantly higher than control. These results should encourage further research to explore citrus-based products as a urolithiasis treatment.

Problems related to a comprehensive assessment of construction materials’ environmental safety, taking into account stages of products’ complete life cycle have been considered. Approaches to determination of material’s safety and environmental record as environmental characteristics of the material, regardless of its use in a specific product, and without regard to processing technology have been described. It has been proposed to consider material’s safety and environmental record as the sum of three environmental safety factors for material’s life cycle stages: production of raw material and its potential environmental hazard; processing of raw material in the material; proper material from the standpoint of its environmental safety and effects on the human body. This criterion application allows compare the environmental properties both of cognate materials and dissimilar ones.

Published: March 2017

The innovative project of application of wind driven generators in units for sea and brackish waters desalination by reversed osmosis method with thermal utilization of salt concentrates and pulse ultra-violet disinfecting has been presented. This project implementation will provide with fresh water residential and industrial facilities, as well as farms in the areas located near the sea coast or having sources of underground brackish waters. This unit development aimed to obtaining fresh water with minimum expense of the salt concentrate in the form of sewage, and in some cases with its complete exception. The technical characteristic of autonomous unit for sea water desalination with performance on desalinated water equal to 50 m3 per day has been presented. Distinctive feature of the autonomous desalination unit is development of a module for pulse ultra-violet disinfecting of water by impact on it with high-intensity pulse ultra-violet wide range radiation and construction of an energy storage device based on a super condensers block which allowed the autonomous wind driven generator to use the energy concluded in wind fluctuations.
Is Reshoring Better Than Offshoring? The Effect of Offshore Supply Dependence
Authors: Chen Li , Hu Bin
Published: March 2017

In this paper we investigate the effect of offshore supply dependence (OSD) on offshoring–reshoring profit comparisons. We find that OSD hampers a reshoring manufacturer’s responsiveness to demand information updates and may significantly affect offshoring–reshoring comparisons, such that reshoring may yield lower profits than offshoring in many cases, including when offshoring has no baseline-cost advantage. We then show that OSD also affects how salient costs such as customs duties and shipping costs influence offshoring–reshoring profit comparisons. We further identify common-component designs as a mitigating measure to make reshoring more appealing under OSD, and numerically confirm the robustness of our results.

Time-Dependent Hazardous-Materials Network Design Problem
Authors: Esfandeh Tolou , Batta Rajan , Kwon Changhyun
Published: March 2017

We extend the hazardous-materials (hazmat) network design problem to account for the time-dependent road closure as a policy tool to reduce hazmat transport risk by altering carriers’ departure times and route choices. We formulate the time-dependent network design problem using an alternative-based model with each alternative representing a combined path and departure-time choice. We also present an extended model that can not only account for consecutive time-based road closure policies but also allow stopping at the intermediate nodes of the network in the routing/scheduling decisions of the carriers. Heuristic algorithms based on column generation and label setting are presented. To illustrate the advantages that can be gained through the use of our methodology, we present results from numerical experiments based on a transportation network from Buffalo, New York. To investigate the impact of the extensions, we consider three versions of the problem by gradually refining the model. We show that under consideration of extensions, the design policies are more applicable and effective.

Meta-Analysis of Price Responsiveness of Timber Supply
Authors: Tian Nana , Poudyal Neelam C. , Augé Robert M. , Hodges Donald G. , Young Timothy M.
Published: March 2017

Modeling and projecting timber supply requires a good understanding of how supply responds to price. The price elasticity of supply (PELS) reported in the literature varies greatly, indicating that conclusions regarding price signaling in the timber market are mixed. Therefore, we conducted a meta-analysis to determine the key factors associated with the heterogeneity of PELS of primary timber product supply by examining data from numerous studies conducted around the world. Twelve “moderator” variables were examined to explore differences in PELS. Moderators with significant impacts on variation of PELS included forest products, geographic regions, econometric models, and data type. Furthermore, two-level categorical variables contained within the econometric models including standing stock were found to have significant influence on the heterogeneity of PELS. Variation in PELS also depended on whether or not the supply models accounted for price inflation, and the time period when the study was conducted. These findings may improve the understanding of the dynamics of price signaling in timber markets, and further improve the efficiency of timber supply and forecasting models for market participants and policy makers.

Published: March 2017

Background The use of growth hormone (GH) is a routinetreatment for growth hormone deficiency (GHD), small forgestational age (SGA), and Turner syndrome (TS). During thetreatment, height measurement at regular intervals is a vital stepto assess success. To date, there have been no previous studieson GH treatment in Dr. Soetomo Hospital, Surabaya, the referralhospital in East Indonesia.Objective To compare body height between pre- and post-growthhormone treatment in pediatric patients.Method This study was a non-randomized, pre-post clinical trialperformed at Dr. Soetomo Hospital, Surabaya. The prospectivecohort was accessed during January 2008-June 2013. Theinclusion criteria was GH treatment for more than 3 months.Clinical data on GH treatment, including diagnosis, age, heightpre-and post-treatment, height gain, duration of treatment, andparental satisfaction were collected. Two-tailed, paired T-test andPearson’s test were used for statistical analyses.Result Nineteen patients underwent GH treatment during thestudy period, but only twelve patients had complete data and wereincluded in the study. Eight subjects were female. Subjects’ meanage was 11 (range 8-15) years. Nine patients had GHD, 2 hadTS, and 1 had SGA. Mean pre-treatment height was 121.05 cm,while mean post-treatment height was 130.5 cm. Mean durationof treatment was 10.5 (range 3-30) months. Mean height gainwas 0.8 cm/month in GHD and SGA cases, and 0.78 cm/monthfor the TS cases. Eleven parents reported satisfaction with theresults of GH treatment in their children. There is significantdiffrent between pre- and post-treatment (P=0.001). Pearson’scorrelation test (r=0.90) revealed a strong correlation betweengrowth hormone treatment and height gain.Conclusion Growth hormone treatment has impact on heights inGH defficiency, Turner syndrome, and small for gestational age.

Background The incidence of childhood leukemia has increasedannually. Recent studies have shown that childhood leukemia isinitiated in utero, and have focused on prenatal risk factors suchas birth weight and parental age. Exposure to pesticides andradiation, as well as parental smoking, breastfeeding, and thenumber of older siblings have also been sugges ted as risk factorsfor childhood leukemia.Objective To evaluate possible risk factors for childhood leukemia,including birth weight, parental age, and other risk factors.Methods This case-con trol study was conducted from October2011 to February 2012 in Haji Adam Malik Hospital, Medan .Case subjects were children aged below 18 years and diagnosedwith leukemia. Control subjects were children aged below 18years who were diagnosed with any non-cancerous acute illnessesin this hospital, and individually matched for age and gen der tothe case subject group. Patients and parents were asked to fill astructured questionnaire. Data was analyzed using conditionallogistic regression .Results A total of 140 subjects were eligible, with 70 subjects ineach group. Birth weight 2: 4000 g and maternal age 2:35 yearswere significant risk factors with OR 10.13 (95%CI 1.124 to 91.2 7)and OR 4.98 (95%CI 1.276 to 19.445), respectively. Paternal ageof 2:35 years was not a significant risk factor. Exposure to pesticideswas also noted as another significant risk factor (OR= 6.66; 95%CI2.021 to 21.966) .Conclusion High birth weight, advan ced maternal age, andexposure to pesticides are risk factors of childhood leukemia.

Preserving the old forms and structural details in case of renovation of buildings is a primary issue. The structure of traditional wooden windows, as eyes of the building, defines the character of the facade, the street view and also influences the character of the whole townscape. With the new building energy regulations energy awareness became conspicuous, which is current requirement during the energy crisis of the XXI. century at national and international levels as well. This paper investigates all the renovation or replacement methods of historic windows should be considered.

Despite the huge research into stem cells and their regenerative properties for bone healing, there are still unanswered questions including the recipient’s respond to the presence of the stem cells, the fate of stem cells inside the bone defect and the possible advantage in utilizing pre-differentiated cells. To address these problems, we used human multipotent mesenchymal stromal/stem cells (MSCs), GMP Grade, in a rat model of bone formation. In a “bioreactor concept” approach seven Wistar rats were implanted with 0.2 g of synthetic bone scaffold seeded with 2 × 106 MSCs, seven Wistar rats were implanted with 0.2 g of synthetic bone scaffold seeded with 1 × 106 predifferentiated osteoblasts and 1 × 106 pre-differentiated endothelial cells and 14 Wistar rats were implanted with 0.2 g of synthetic bone scaffold without seeded cells into an intramuscular pocket on the left side of their back. The right side of each rat was used as a control, and 0.2 g of synthetic bone scaffold was implanted into the intramuscular pocket alone. To see the early stage healing the samples were harvested 14 days after the implantation, MSCs were detected by positive DAPI and MTCO2 staining in 43% of all the samples implanted with MSCs, and no inflammation signs were present in any implanted animal. New vessels could be found in both groups implanted with MSCs, but not in the control group of animals. However, hematoxylin-eosin staining could not detect newly created bone within the implant in any of the groups. These results were in line with COLL1 staining, where we could detect positive staining only in three cases, all of which were implanted with un-differentiated MSCs. According to our findings, there were no benefits of using the pre-differentiated of MSC.
On stabilizers of algebraic function fields of one variable

LetK~$\tilde K$be a fixed algebraic closure of an infinite fieldK. We consider an absolutely integral curveΓinPKn$\mathbb{P}_{K}^{n}$withn≥ 2. The curveΓK~$\it\Gamma_{\tilde{K}}$should have only finitely many inflection points, finitely many double tangents, and there exists no point inPK~n$\mathbb{P}_{\tilde{K}}^{n}$through which infinitely many tangents toΓK~$\it\Gamma_{\tilde{K}}$go. In addition there exists a prime numberqsuch thatΓK~$\it\Gamma_{\tilde{K}}$has a cusp of multiplicityqand the multiplicities of all other points ofΓK~$\it\Gamma_{\tilde{K}}$are at mostq. Under these assumptions, we construct a non-empty Zariski-open subsetOofPK~n$\mathbb{P}_{\tilde{K}}^{n}$such that ifn≥ 3, the projection from each pointo∈O(K) birationally mapsΓonto an absolutely integral curveΓ′inPKn−1$\mathbb{P}_{K}^{n-1}$with the same properties asΓ(keepingqunchanged). Ifn= 2, then the projection from eacho∈O(K) mapsΓontoPK1$\mathbb{P}_{K}^{1}$and leads to astabilizingelementtof the function fieldFofΓoverK. The latter means thatF/K(t) is a finite separable extension whose Galois closureF^${\hat F}$is regular overK.
