Psychosocial Maturity and Risk-Taking in Emerging Adults: Extending Our Understanding Beyond Delinquency
Authors: Riggs Romaine Christina L.
Published: May 2018

Risk-taking behaviors in adolescence and emerging adulthood are highly prevalent and come with far-reaching social, health, and safety implications. Understanding the factors influencing these behaviors remains an important priority. Psychosocial maturity (PSM) is known to influence one type of risk-taking: delinquency. This study examined how PSM relates to (1) broader risk-taking behaviors in emerging adulthood and (2) risk-taking style across domains (e.g., social and recreational risk) to explore if PSM may be an appropriate target for future risk-reduction interventions. Emerging adults ( N = 538) completed measures of PSM, recent risky behavior, and risk-taking style in various domains. All aspects of PSM were related to different risk-taking styles, but only temperance (impulsivity) was consistently associated with various behaviors (e.g., alcohol consumed, distracted driving, and delinquency). Implications for prevention, intervention, and policy are discussed.

Authors: Roward Zachary , Latt L. Daniel
Published: May 2018

Anatomic lateral ankle ligament reconstruction using free tendon graft with osseous tunnels has become a popular technique for revision reconstruction of the lateral ankle ligaments. With the procedure’s burgeoning popularity, an accompanying increase in postoperative complications is likely to occur. We report on one such complication: traumatic distal fibula fracture through the transosseous tunnels.

Published: May 2018

Backbround

COPD is a common, highly debilitating disease of the airways, primarily caused by smoking. Chronic inflammation and structural remodelling are key pathological features of this disease caused, in part, by the aberrant function of airway smooth muscle (ASM). We have previously demonstrated that hydrogen sulfide (H2S) can inhibit ASM cell proliferation and CXCL8 release, from cells isolated from non-smokers.

Methods

We examined the effect of H2S upon ASM cells from COPD patients. ASM cells were isolated from non-smokers, smokers and patients with COPD (n = 9). Proliferation and cytokine release (IL-6 and CXCL8) of ASM was induced by FCS, and measured by bromodeoxyuridine incorporation and ELISA, respectively.

Results

Exposure of ASM to H2S donors inhibited FCS-induced proliferation and cytokine release, but was less effective upon COPD ASM cells compared to the non-smokers and smokers. The mRNA and protein expression of the enzymes responsible for endogenous H2S production (cystathionine-β-synthase [CBS] and 3-mercaptopyruvate sulphur transferase [MPST]) were inhibited by H2S donors. Finally, we report that exogenous H2S inhibited FCS-stimulated phosphorylation of ERK–1/2 and p38 mitogen activated protein kinases (MAPKs), in the non-smoker and smoker ASM cells, with little effect in COPD cells.

Conclusions

H2S production provides a novel mechanism for the repression of ASM proliferation and cytokine release. The ability of COPD ASM cells to respond to H2S is attenuated in COPD ASM cells despite the presence of the enzymes responsible for H2S production.
What is a smart device? - a conceptualisation within the paradigm of the internet of things
Authors: Silverio-Fernández Manuel , Renukappa Suresh , Suresh Subashini
Published: May 2018

The Internet of Things (IoT) is an interconnected network of objects which range from simple sensors to smartphones and tablets; it is a relatively novel paradigm that has been rapidly gaining ground in the scenario of modern wireless telecommunications with an expected growth of 25 to 50 billion of connected devices for 2020 Due to the recent rise of this paradigm, authors across the literature use inconsistent terms to address the devices present in the IoT, such as mobile device, smart device, mobile technologies or mobile smart device. Based on the existing literature, this paper chooses the term smart device as a starting point towards the development of an appropriate definition for the devices present in the IoT. This investigation aims at exploring the concept and main features of smart devices as well as their role in the IoT. This paper follows a systematic approach for reviewing compendium of literature to explore the current research in this field. It has been identified smart devices as the primary objects interconnected in the network of IoT, having an essential role in this paradigm. The developed concept for defining smart device is based on three main features, namely context-awareness, autonomy and device connectivity. Other features such as mobility and user-interaction were highly mentioned in the literature, but were not considered because of the nature of the IoT as a network mainly oriented to device-to-device connectivity whether they are mobile or not and whether they interact with people or not. What emerges from this paper is a concept which can be used to homogenise the terminology used on further research in the Field of digitalisation and smart technologies.

Published: May 2018

Background

The long-acting injectable antipsychotic aripiprazole once-monthly 400 mg (AOM 400) was recently approved for maintenance treatment of bipolar I disorder (BP-I). The purpose of this study was to evaluate the safety, tolerability, and efficacy of AOM 400 as long-term maintenance treatment for BP-I.

Methods

This open-label multicenter study evaluated the effectiveness of AOM 400 as maintenance treatment for BP-I by assessing safety and tolerability (primary objective) and efficacy (secondary objective). The study enrolled AOM 400-naive (“de novo”) patients as well as AOM 400-experienced (“rollover”) patients with BP-I from a lead-in randomized, placebo-controlled clinical trial that demonstrated the efficacy of AOM 400 in the maintenance treatment of BP-I (Calabrese et al. in J Clin Psychiatry 78:324–331, 2017). Safety variables included frequency and severity of treatment-emergent adverse events (TEAEs) and TEAEs resulting in study discontinuation. Efficacy was assessed by the proportion of patients maintaining stability throughout the maintenance phase, as well as mean changes from baseline in Young Mania Rating Scale (YMRS), Montgomery–Asberg Depression Rating Scale, and Clinical Global Impressions for Bipolar Disorder–Severity of Illness Scale (CGI-BP-S) total scores. Patient acceptability and tolerability of treatment was assessed using the Patient Satisfaction with Medication Questionnaire-Modified.

Results

Of 464 patients entering the maintenance phase, 379 (82%) were de novo and 85 (18%) were rollover. TEAEs were more common in de novo than rollover patients. The overall discontinuation rate due to TEAEs was 10.3% (48/464). Improvements in YMRS and CGI-BP-S total scores were maintained during the study, and the vast majority of both de novo (87.0%) and rollover (97.6%) patients maintained stability through their last visit. Overall, the need for rescue medication during the maintenance phase was minimal (< 10% of patients). Patient satisfaction levels were high, with both de novo and rollover patients rating the side effect burden of AOM 400 as greatly improved relative to previous medications.

Conclusion

AOM 400 was safe, effective, and well tolerated by both de novo and AOM 400-experienced patients with BP-I for long-term maintenance treatment.

Published: May 2018

Background

Enlarged retropharyngeal lymph nodes (RLNs) are very common in patients with nasopharyngeal carcinoma (NPC) undergoing radiotherapy. The most suitable treatment option for enlarged RLNs depends on the pathological results. However, RLN sampling is difficult and imminent in the clinic setting. We recently developed a novel minimally invasive technique termed endoscopic ultrasound‐guided fine needle aspiration (EUS‐FNA) for sampling RLN tissues sufficient for pathological or cytological diagnosis.

Methods

We enrolled 30 post‐radiotherapy patients with NPC with suspected RLN metastasis detected via magnetic resonance imaging (MRI). The EUS probe was introduced into the nasopharynx via the nostrils, and EUS was then used to scan the retropharyngeal space and locate the RLN in the anterior carotid sheath. EUS‐FNA was subsequently performed. The safety and efficacy of using EUS‐FNA to sample the RLN tissues were assessed.

Results

Strips of tissue were successfully sampled from all patients using EUS‐FNA. Of the 30 patients, 23 were confirmed to have cancer cells in the biopsied tissues via pathology or cytology examinations with 1 EUS‐FNA biopsy session. The seven cases without confirmed cancer cells were subsequently reanalyzed by using another EUS‐FNA biopsy session, and two more cases were confirmed possessing cancer cells. The other five patients without confirmed cancer cells were closely followed with MRI every month for 3 months. After follow‐up for 3 months, three patients were still considered cancer‐free due to the presence of RLNs with stable or shrinking diameters. The rest two patients who showed progressive disease underwent a third EUS‐FNA biopsy procedure and were further confirmed to be cancer cell‐positive. In the whole cohort reported here, the EUS‐FNA procedure was not associated with any severe complications.

Conclusion

EUS‐FNA is a safe and effective diagnostic approach for sampling tissues from the RLNs in patients with suspected recurrent NPC.
Human vision system-based structural similarity model for evaluating seismic image quality
Authors: Yang Ning , Duan Yi
Published: May 2018

The quality of a seismic section is generally evaluated based on relevant qualitative and quantitative criteria. We have developed a new quantitative model to evaluate seismic sections, i.e., a full-reference human visual system based on seismic image structural similarity. With this model, we compared and analyzed two seismic sections before and after data processing in terms of energy intensity, contrast, and seismic reflection configuration similarity measures. We evaluated the quality of the seismic section in combination with the three measures, and their changing trends before and after data processing are represented with relevant quantitative indicators. The numerical simulation used algorithms and actual data, and the results indicate that compared with conventional evaluation methods, our method is easier to understand and simpler to calculate. Our method can also highlight the differences between changing seismic sections and improve the consistency of the objective evaluation results of seismic images with the corresponding human subjective perception.

Published: May 2018

Background

Pathological worry is a hallmark feature of generalised anxiety disorder (GAD), associated with dysfunctional emotional processing. The ventromedial prefrontal cortex (vmPFC) is involved in the regulation of such processes, but the link between vmPFC emotional responses and pathological v. adaptive worry has not yet been examined.

Aims

To study the association between worry and vmPFC activity evoked by the processing of learned safety and threat signals.

Method

In total, 27 unmedicated patients with GAD and 56 healthy controls (HC) underwent a differential fear conditioning paradigm during functional magnetic resonance imaging.

Results

Compared to HC, the GAD group demonstrated reduced vmPFC activation to safety signals and no safety–threat processing differentiation. This response was positively correlated with worry severity in GAD, whereas the same variables showed a negative and weak correlation in HC.

Conclusions

Poor vmPFC safety–threat differentiation might characterise GAD, and its distinctive association with GAD worries suggests a neural-based qualitative difference between healthy and pathological worries.

The New Foucault Effect
Authors: Gane Mike
Published: May 2018

This review article considers two lecture courses by Michel Foucault (1972–73, 1979–80) and two books relating to the whole series of lectures (1970–84) by Stuart Elden. Foucault’s lecture courses can be divided into three phases, the first focused on the difference between sovereign and disciplinary power; the second on biopower, security, and liberalism; and the third on the government of the self and others. Foucault in 1976–79 altered his earlier frame by introducing the concept of governmentality and security dispositif and identified a missing, fourth type of power-governmentality called “socialism,” around which his concerns revolved for the remaining courses. Today there is a new Foucault effect, which has arisen around the courses on governmentality, neoliberalism, and biopower. The two courses by Foucault are situated in relation to the complete set of courses, and Elden’s books are welcomed critically as throwing light on the background to the lectures and Foucault’s main publications in this period but are problematic with respect to Foucault’s theoretical framework.
Case Report: A Primordial odontogenic tumor
Authors: Amer Hatem , Hafed Layla , Ibrahim Sally
Published: May 2018

Introduction: Primordial odontogenic tumors are a rare recently described mixed odontogenic tumor composed histopathologically of dental papilla like tissue and enamel organ like tissue. Only nine cases have been documented worldwide and we are reporting the tenth case which is from Egypt.

Clinical finding: A 2-year-old Egyptian boy that presented with an asymptomatic swelling of the mandible which appeared with multilocular radiolucency associated with an impacted developing tooth on a computerized tomography (CT) scan.

Diagnoses, interventions, and outcomes: The lesion was excised and diagnosed as a primordial odontogenic tumor. The patient was followed up for two years with no recurrence.

Conclusion: Differentiation of primordial odontogenic tumors from other odontogenic tumors, which resemble it histopathologically is crucial to avoid unnecessary aggressive treatment.
A molecular phylogeny of selligueoid ferns (Polypodiaceae): Implications for a natural delimitation despite homoplasy and rapid radiation

Published: May 2018

Homoplasy, autapomorphy and rapid radiation have frequently been discussed as the main causes of instable generic classifications of plants including ferns. In this study, we explore the natural generic classification for selligueoid ferns by investigating the phylogenetic relationships among almost all its previously recognized segregates. We compare the phylogenies that resulted from two datasets. Dataset 1 comprises a broad taxonomic sampling of fifty–one species of selligueoid ferns. Phylogenetic analysis of this dataset revealed a notable long branch followed by a polytomy recovering three core clades of selligueoid ferns. Only one of the core clades corresponds to the traditional generic concept of Arthromeris. Dataset 2 includes fewer species but a broader sample of six plastid DNA markers. However, the results of this dataset show that the increase of informative molecular characters still did not provide sufficient evidence to resolve the polytomy. The long branches together with a consistent backbone polytomy support a rapid radiation in the selligueoid ferns. The majority of morphological characters were recovered as homoplastic, which hampers the identification of segregates with unambiguous diagnostic characters. Considering morphological characters and our molecular phylogeny, a single genus Selliguea s.l., which includes all selligueoid species, is proposed here to achieve taxonomic stability in this group.

The pantropical genus Begonia is the sixth–largest genus of flowering plants, including 1870 species. The sections of Begonia are used frequently as analogues to genera in other families but, despite their taxonomic utility, few of the current sections have been examined in the light of molecular phylogenetic analyses. We present herein the largest, most representative phylogeny of Begonia published to date and a subsequent provisional sectional classification of the genus. We utilised three plastid markers for 574 species and 809 accessions of Begonia and used Hillebrandia as an outgroup to produce a dated phylogeny. The relationships between some species and sections are poorly resolved, but many sections and deeper nodes receive strong support. We recognise 70 sections of Begonia including 5 new sections: Astrothrix, Ephemera, Jackia, Kollmannia, and Stellandrae; 4 sections are reinstated from synonymy: Australes, Exalabegonia, Latistigma and Pereira; and 5 sections are newly synonymised. The new sectional classification is discussed with reference to identifying characters and previous classifications.
Generic delimitation in Apocyneae (Apocynaceae)

Published: May 2018

Apocyneae are a tribe of 24 genera and ca. 113 species that, with the exception of the temperate Apocynum species in North America and Eurasia, are all woody vines endemic to tropical and subtropical Asia and Australasia. Generic concepts have been in flux through most of the history of the taxa now grouped in Apocyneae and have been only partially clarified in previously published molecular phylogenetic studies. Expanded taxon and character sampling permitted a phylogenetic analysis based on gene sequences from four chloroplast and three nuclear loci of 23 of 24 currently recognized genera, and 23 morphological characters scored for all 24 genera. The resulting topology supports the expansion of Micrechites to include the monotypic Vallariopsis, united by the shared presence of unusual polyporate pollen, and Urceola to include Parameria and Aganonerion, united by the shared presence of acarodomatia and pubescent seeds. The required combinations are made. Ixodonerium is placed as sister to Papuechites, supported by the synapomorphic presence of a corolline corona. Monophyly of Epigynum is supported for the first time, based primarily on evidence from the nuclear Leafy intron; no unambiguously optimized morphological synapomorphies are identified. Baharuia, included based on morphology only, is placed as sister to or nested within Urceola s.l., supported by the synapomorphic presence of acarodomatia. The subtribal classification is modified to reflect our current understanding of phylogeny: Baharuia is transferred to Urceolinae, Micrechites and Amalocalyx are transferred to Chonemorphinae, and Streptoechites is treated as subtribe incertae sedis.
Adaptive Distributionally Robust Optimization
Authors: Bertsimas Dimitris , Sim Melvyn , Zhang Meilin
Published: May 2018

We develop a modular and tractable framework for solving an adaptive distributionally robust linear optimization problem, where we minimize the worst-case expected cost over an ambiguity set of probability distributions. The adaptive distributionally robust optimization framework caters for dynamic decision making, where decisions adapt to the uncertain outcomes as they unfold in stages. For tractability considerations, we focus on a class of second-order conic (SOC) representable ambiguity set, though our results can easily be extended to more general conic representations. We show that the adaptive distributionally robust linear optimization problem can be formulated as a classical robust optimization problem. To obtain a tractable formulation, we approximate the adaptive distributionally robust optimization problem using linear decision rule (LDR) techniques. More interestingly, by incorporating the primary and auxiliary random variables of the lifted ambiguity set in the LDR approximation, we can significantly improve the solutions, and for a class of adaptive distributionally robust optimization problems, exact solutions can also be obtained. Using the new LDR approximation, we can transform the distributionally adaptive robust optimization problem to a classical robust optimization problem with an SOC representable uncertainty set. Finally, to demonstrate the potential for solving management decision problems, we develop an algebraic modeling package and illustrate how it can be used to facilitate modeling and obtain high-quality solutions for medical appointment scheduling and inventory management problems.

Robust Optimization with Ambiguous Stochastic Constraints Under Mean and Dispersion Information
Authors: Postek Krzysztof , Ben-Tal Aharon , den Hertog Dick , Melenberg Bertrand
Published: May 2018

In this paper we consider ambiguous stochastic constraints under partial information consisting of means and dispersion measures of the underlying random parameters. Whereas the past literature used the variance as the dispersion measure, here we use the mean absolute deviation from the mean (MAD). This makes it possible to use the 1972 result of Ben-Tal and Hochman (BH) in which tight upper and lower bounds on the expectation of a convex function of a random variable are given. First, we use these results to treat ambiguous expected feasibility constraints to obtain exact reformulations for both functions that are convex and concave in the components of the random variable. This approach requires, however, the independence of the random variables and, moreover, may lead to an exponential number of terms in the resulting robust counterparts. We then show how upper bounds can be constructed that alleviate the independence restriction, and require only a linear number of terms, by exploiting models in which random variables are linearly aggregated. Moreover, using the BH bounds we derive three new safe tractable approximations of chance constraints of increasing computational complexity and quality. In a numerical study, we demonstrate the efficiency of our methods in solving stochastic optimization problems under mean-MAD ambiguity.

Published: May 2018

The acute and subacute forms of equine grass sickness (EGS) are invariably fatal. In comparison, approximately 45–55% of cases with the chronic form of EGS recover with intensive nursing care. Prior to, and throughout the period of nursing, the clinician can be faced with difficult decision making dilemmas, including the identification of suitable candidates for treatment, the selection of an applicable treatment plan and the establishment of appropriate criteria to inform the decision for continued treatment or euthanasia. This article will cover the various aspects of nursing care and will also address some of the difficult clinical decisions, the outcomes of which have a major impact both on the case and the owner.
Suspensory branch injuries in sports horses and racehorses
Authors: Dyson Sue
Published: May 2018

Suspensory ligament (SL) branch injuries are a common cause of lameness or poor performance in racehorses and sports horses. In Thoroughbred racehorses forelimb injuries predominate, whereas in sports horses injuries occur in both forelimbs and hindlimbs, sometimes in association with proximal suspensory desmopathy. Significant injury can occur without palpable abnormalities; the presence of palpable enlargement in the region of a SL branch may reflect periligamentous fibrosis in some horses, which has an adverse influence on prognosis. In racing Thoroughbreds, the presence of SL branch injury ± sesamoiditis has a negative influence on racing performance. There is currently a lack of evidence-based information about response to treatment, particularly in sports horses. Injection of platelet-rich plasma is of questionable value. Degenerative lesions with resultant hyperextension of the fetlock have a poor prognosis for athletic function

To investigate and compare, the essential oil composition of different parts of two Scandix species (Apiaceae). The essential oil of the aerial parts of two species was obtained by hydrodistillation and analyzed by gas chromatography (GC) and gas chromatography - mass spectrometry (GC-MS). The essential oil yields of S. stellata were determined as 0.3(v/w) in aerial part, 0.2 (v/w) in leaf and fruits. 51 constituents were identified and comprised 85.1 % of the total essential oil from S. stellata Banks et. Sol. aerial parts, and identified thirty constituents in leaf and 27 constituents in fruits and also comprised 98.1% in leaf and 88.9% in fruit total essential oil. Fourty two constituents were identified and comprised 96.6% of the total essential oil from S. iberica aerial parts. The predominant compounds of the aerial part oils of S. stellata were n-hexadecanoic (15.9%) and oleic acids (10.0%), spathulenol (9.4%) and also n- hexadecanoic (27.5%), oleic acids (14.2%), spathulenol (12.1%) and stearic acid (8.2%) were the major compounds in fruit. In S.stellata leaf oil, n-hexadecanoic acid (12.5%), spathulenol (12.1%) and germacrene-D (6.2%) were the major compounds. The predominant compounds of S. iberica oil were n-hexadecanoic acid (23.1%), 1-Octadecane-sterol (31.1%) in aerial parts; pentadecane (28.1%) caryophyllene oxide (10.2%) and heptadecane (9.1%) in leafs ?-monolein (18.1%), n-hexadecanoic acid (12.5%), 1-Octadecane-sterol (11.4%), spathulenol (9.1%) were determined as main compounds in oil of S. iberica fruits. Fatty acid, sesquiterpene and saturated hydrocarbons were determined as significant compounds for the characterization of S. stellata and S. iberica essential oil.

Authors: Mohammadi Farhadi Rahman , Kortunov Vyacheslav , Molchanov Andrii , Solianyk Tatiana
Published: May 2018

Stability and control derivatives of Skywalker X8 flying wing from flight-test data are estimated by using the combination of the output error and least square methods in the presence of the wind. Data is collected from closed loop flight tests with a proportional-integral-derivative (PID) controller that caused data co-linearity problems for the identification of the unmanned aerial vehicle (UAV) dynamic system. The data co-linearity problem is solved with a biased estimation via priori information, parameter fixing and constrained optimization, which uses analytical values of aerodynamic parameters, the level of the identifiability and sensitivity of the measurement vector to the parameters. Estimated aerodynamic parameters are compared with the theoretically calculated coefficients of the UAV, moreover, the dynamic model is validated with additional flight-test data and small covariances of the estimated parameters.

The solution of three-dimensional (3D) coordinate calculation task for a material point is considered. Two flat images (a stereopair) which correspond to the left and to the right viewpoints of a 3D scene are used for this purpose. The stereopair is obtained using two cameras with parallel optical axes. The analytical formulas for calculating 3D coordinates of a material point in the scene were obtained on the basis of analysis of the stereoscopic system optical and geometrical schemes. The detailed presentation of the algorithmic and hardware realization of the given method was discussed with the the practical. The practical module was recommended for the determination of the optical system unknown parameters. The series of experimental investigations were conducted for verification of theoretical results. During these experiments the minor inaccuracies were occurred by space distortions in the optical system and by it discrecity. While using the high quality stereoscopic system, the existing calculation inaccuracy enables to apply the given method for the wide range of practical tasks.

Published: May 2018

The Mahu Depression is an important hydrocarbon-bearing foreland sag located at the northwestern margin of the Junggar Basin, China. On the northern slope of the depression, large coarse-grained proximal fan-delta depositional systems developed in the Lower Triassic Baikouquan Formation (T1b). Some lithologic hydrocarbon reservoirs have been found in the conglomerates of the formation since recent years. However, the rapid vertical and horizontal lithology variations make it is difficult to divide the base-level cycle of the formation using the conventional methods. Spectral analysis technologies, such as Integrated Prediction Error Filter Analysis (INPEFA), provide another effective way to overcome this difficultly. In this paper, processed by INPEFA, conventional resistivity logs are utilized to study the base-level cycle of the fan-delta depositional systems. The negative trend of the INPEFA curve indicates the base-level fall semi-cycles, adversely, positive trend suggests the rise semi-cycles. Base-level cycles of Baikouquan Formation are divided in single and correlation wells. One long-term base-level rise semi-cycle, including three medium-term base-level cycles, is identified overall the Baikouquan Formation. The medium-term base-level cycles are characterized as rise semi-cycles mainly in the fan-delta plain, symmetric cycles in the fan-delta front and fall semi-cycles mainly in the pro-fan-delta. The short-term base-level rise semi-cycles most developed in the braided channels, sub-aqueous distributary channels and sheet sands. While, the interdistributary bays and pro-fan-delta mud indicate short-term base-level fall semi-cycles. Finally, based on the method of INPEFA, sequence filling model of Baikouquan formation is established.

Authors: Slach Ondřej , Ivan Igor , Ženka Jan , Sopkuliak Andrej
Published: May 2018

The principal objective of this paper is to evaluate the spatial patterns of creative industries in a micro-geographic perspective. As the creative industries represent a highly heterogeneous complex, only selected creative industries were studied (culture, marketing and advertising, printing, publishing, architecture). The polycentric industrial city of Ostrava was chosen as the surveyed area. Various spatial statistical methods (e.g. nearest neighbour analysis, kernel density estimation) were applied for the needs of assessment. The results show that spatial patterns of creative industries at intra-urban level do not vary significantly from their counterparts in Western Europe. Despite the fact that Ostrava is highly industrialized polycentric city with relatively weak position of the city centre, creative industries are highly concentrated into the historical city centre and the inner city.
Intake of fruit, vegetables and milk products and correlates among school boys in Saudi Arabia
Authors: Alsubaie Ali Saad R.
Published: May 2018

Background

Healthy dietary behaviors have a significant impact on children’s health and development. Diets high in fruit and vegetables demonstrate a strong and consistent pattern for decreasing the risk of and providing benefits against cardiovascular disease, diabetes, obesity and many cancers. Yet, little is known about the pattern of fruit, vegetables and dairy products consumption among children in Saudi Arabia.

Objectives

The aim of this study was to investigate the consumption of fruit, vegetables and milk products and their dietary correlates among school boys in Saudi Arabia.

Materials and methods

A multistage stratified cluster cross-sectional survey, using a pre-tested questionnaire was conducted among school-children. The study sample comprised of 725 school students from ten randomly selected schools in Saudi Arabia.

Results

All surveyed schools (100%) neither provide nor sell fruit, fresh juices or vegetables on their premises. During regular weekdays, the majority of the children did not consume fruit (69%) and vegetables (71.4%) on daily basis. More than one third (32.4%) of the children did not consume dairy products daily. The daily consumption of fruit and dairy products were associated with young age [odds ratio (OR) = 1.5, confidence interval (CI): 1.1–2.2, p = 0.040] and (OR = 2.4, CI: 1.6–3.7, p = 0.001), respectively. Daily consumption of fruit was positively associated with daily consumption of vegetables (OR = 6.6, CI: 4.5–9.5, p = 0.001). Also, daily consumption of vegetables was positively associated with daily consumption of dairy products (OR = 1.5, CI: 1.1–2.2, p = 0.040) and inversely correlated with daily consumption of sweets (OR = 0.6, C.I: 0.4–0.9, p = 0.012). Moreover, the daily consumption of dairy products was associated with consuming high fat food daily (OR = 1.7, CI: 1.2–2.4, p = 0.002).

Conclusion

The findings indicated that a high percentage of children in Saudi Arabia had an unhealthy low consumption of fruit, vegetables and milk products. Thus, an intervention program to promote healthy dietary patterns is highly recommended. Improving school environments and establishing school-based nutrition programs are extremely needed to promote healthy dietary behaviors among this age group.

Zwangsehen und Bastarde

Taucht das Wort „Wissenschaft“ im Zusammenhang mit Big Data auf, denkt man zumeist an Wissenschaftler, die durch findige Analysen treffsichere Prognosen über zukünftige Entwicklungen, Ereignisse und Handlungen fällen – oder aber mit chirurgischer Präzision Verhalten beeinflussen, wie etwa vom erfolgreichen Wahlkampf Donald Trumps kolportiert. Allerdings sind Wissenschaftler längst nicht mehr nur Agenten in Big-Data-Szenarien, sondern auch Objekte. Die Vermessung der Wissenschaft erfolgt heute nicht allein anhand simpler Zitationszählungen oder erwirtschafteter Projektgelder: Kommerzielle Akteure schicken sich an, ein ganzes Betriebssystem inklusive integrierter Werkzeuge zu schaffen, das unablässig Verhalten von Wissenschaftlern und Performanz von Wissenschaft protokolliert. Der Beitrag illustriert am Wandel des früheren Verlagshauses Elsevier zum Research Intelligence Provider exemplarisch, wie Wissenschaft selbst in den Fokus von Big Data gerät und wie eine Big-Data-gesteuerte Wissenschaft aussehen könnte.

We also provide an explicit formula for a wave function associated with a recent work by the present author and M. Wolf.
A Land with No Borders: A New Interpretation of the Babylonian “Map of the World”
Authors: Delnero Paul
Published: May 2018

The Babylonian Map of the World, which is arguably one of the most famous and frequently referenced artifacts from Ancient Mesopotamia, has almost without exception been assumed to present an idealized and highly ideological picture of the cosmos with the city of Babylon occupying its privileged center. While there can be little question that dichotomies such as myth and reality, core and periphery, and past and the present, merge together seamlessly in the Map (and its accompanying texts) to present an idealized image of Babylonia, it will be argued in this paper that focusing on these dichotomies has caused critical aspects of the Map to be overlooked. By examining the Map as a dynamic, as opposed to static image, a new interpretation of the Map will be presented to show how this remarkable artifact connects the Mesopotamian past and present with its real and mythological landscapes in a way that has been previously unexplored.

In modern medical research and development, the variety of research tools has extended in the previous years. Exploiting the benefits of shared hardware platforms and software frameworks is crucial to keep up with the technological development rate. Sharing knowledge in terms of algorithms, applications and instruments allows researchers to help each other’s work effectively. Community workshops and publications provide a throughout overview of system design, capabilities, know-how sharing and limitations. This paper provides sneak peek into the emerging collaborative platforms, focusing on available open-source research kits, software frameworks, cloud applications, teleoperation training environments and shared domain ontologies.
Implementation of Embedded Linux Systems on FPGA Based Circuits for Real Time Process Control
Authors: Hajdu Szabolcs , Brassai Sándor-Tihamér
Published: May 2018

This paper presents a framework based on embedded SOC systems, which allows the testing and use of control algorithms implemented on FPGA circuits. For monitoring and parameterization a real-time Linux operating system was used. In this paper different methods for data exchange between the operating system and the control unit were introduced. The delay between the operating system and the control unit during the data exchange was studied and the measurement results discussed reflect the real-time functionality of the system.
Disability Roles: Challenges Concerning the Education of People Living with Disabilities in Hungary
Authors: Laki Ildikó
Published: May 2018

One of the paths toward the social integration of people living with disabilities is to guarantee their participation in education and employment in the long term. The European Union emphasises the concept of lifelong learning to achieve the goals of improved education levels and the concomitant employability for this group. Although in the past few years there have been positive developments in the conditions of people living with disabilities in Hungary. Therefore, it remains one of the challenges of the Hungarian adult education system to bring about equal opportunities in participation for people living with disabilities. The main dilemma refers primarily to the provisioning of the wide array of learning aids required due to the diverse nature of possible disabilities and the establishment of a supportive and conducive learning environment.
The presence of Polish, Hungarian and Slovak Publications in the Field of Education in the Web of Science Database. A Bibliometric Comparative Study
Authors: Rębisz Sławomir
Published: May 2018

The author of this article aims at comparing the publication activity of scholars from Poland, Slovakia and Hungary in education in the period of 1994-2014. Based on the comparative analyses, the author sought to determine: (1) trends in the scholarly performance in the analysed field of study (increase/decrease), (2) leading scientific institutions with the largest number of publications in the field of education, (3) scale of internationalization (international co-authorship). Furthermore (4) the author discusses the participation of scientists from the countries under analysis in the European (EU) and worldwide circulation of scholarly papers in the field of education. To perform the analyses, first the representative source had to be chosen. Considering that what is valued in science, also in Europe, is the prestige of a journal in which a paper is published while the overall science hierarchy is primarily based on the global grading of scholarly journals, we have chosen to use the data from the Thomson/Reuters database (Web of ScienceTM Core Collection) containing an index of selected papers with the so-called impact factor (IF), a well-known global indication of citation impact. Several publications in the journals with high IF is a confirmation of the high quality of scientific research while it also determines the level of internationalization of science. This study was conducted over twenty years (1994-2014) to make sure it was representative of the publishing activity and international output of scholars from the countries under analysis.

Riassunto:

L’articolo tratta delle misure assistenziali in pro dei sinistrati di guerra nell’Italia repubblicana, ma nell’ottica di inquadrare tali provvedimenti nel più ampio contesto dei nuovi diritti di cittadinanza sanciti con la Carta costituzionale del 1947. Andando oltre il già noto nesso tra warfare e welfare, l’articolo ricostruisce l’esercizio di tali nuovi diritti (un vero e proprio „diritto al benessere“ che, preso a „fondamento della nuova cittadinanza“, è stato giudicato come uno dei punti cardine della transizione tra guerra e dopoguerra) da parte di una categoria sovente giudicata dallo Stato meritevole delle più ampie attenzioni, ma che lamentò molto spesso la trascuratezza da parte delle istituzioni nel garantirle quanto stabilito dalla legge. L’ipotesi di partenza è, pertanto, che tali difficoltà abbiano contribuito a minare l’affezione di una porzione non piccola della cittadinanza rispetto alle nuove istituzioni democratiche, molto fragili nei primi anni del dopoguerra. L’articolo analizza nello specifico alcuni casi di pratiche pensionistiche, relative a diverse categorie di beneficiari, afflitte però dai medesimi problemi: in particolare, la lentezza talvolta sconcertante con cui il Dipartimento Generale delle Pensioni di Guerra – che pure era, in effetti, letteralmente inondata di domande di pensione – gestiva l’iter delle pratiche, tanto che alcune si sono trascinate sino agli anni ’90. Il cittadino che faceva richiesta di pensione di guerra (che spettava agli invalidi per cause di guerra con almeno il 30 per cento di capacità lavorativa perduta) doveva spesso attendere anni anche soltanto per avere una prima risposta. Ciò provocava un fenomeno ricorrente, cioè quello di rivolgersi alle più diverse personalità ed autorità politiche auspicando la loro intercessione: non percependo la forza del diritto, ci si rifugiava nella speranza di una generosità paternalistica. Talvolta, queste lettere – di rabbia, e di supplica – addirittura precedevano i gravi ritardi dell’espletamento delle pratiche, segnalando dunque l’esistenza di una consuetudine predemocratica nei suoi stessi presupposti. Uno dei segnali di una condizione di cittadinanza rimasta incompiuta.
