Authors: Dilytė Asta , Lazutka Romas
Published: February 2017

Straipsnyje analizuojama jaunimo dalyvavimą politikoje lemianti institucinė struktūra. Darbo tikslas – pateikti jaunimo dalyvavimą politikoje lemiančių institucijų aprašą. Institucijos yra suprantamos racionalaus pasirinkimo neoinstitucionalizmo teorijos perspektyvoje. Jaunimo dalyvavimą politikoje lemianti institucinė struktūra yra analizuojama remiantis Elinor Ostrom pasiūlyta institucijų analizės perspektyva. Institucijas išreiškiantys teisės aktai buvo analizuojami naudojant kokybinę turinio analizę. Rezultatai atskleidžia, kad Lietuvoje iš esmės jaunimas gali dalyvauti politikoje. Tačiau jaunimo dalyvavimas politikoje nėra pastiprinamas ir žvelgiant pro racionalaus pasirinkimo teorijos prizmę nelabai motyvuojamas – yra daug išlaidų, susijusių su dalyvavimu, o nauda ir pastiprinimas yra menki.

Authors: Poviliūnas Arūnas
Published: February 2017

Straipsnyje siekiama galima atsakyti į klausimą, kodėl Lietuvos socialinės įtraukties politikos profilis yra būtent toks, koks jis yra. Kritiškai aptariamas socialinės įtraukties politikos konvergenciją turėjęs ir vis dar turintis skatinti atviro koordinavimo metodas bei naujas Europos Sąjungos politikų ir biurokratų rengiamas instrumentas Europos socialinių teisių piliorius (European Pillar for Social Rights). Apibūdinant socialinės įtraukties politikos profilį ir iliustruojant jį konkrečiais socialinės politikos pavyzdžiais, formuluojama socialinės politikos konvergencijos ir divergencijos dichotomija. Ieškant paaiškinimo, kodėl socialinės įtraukties politika, užuot konvergavusi, diverguoja, pasitelkiamos priklausomybės nuo tako teorija, kuri pabrėžia transakcinius institucinių konsteliacijų kaitos kaštus, ir socialinio žinojimo tipologijos teorija, kuri suteikia įrankių aiškintis, kaip institucinės konsteliacijos įsitvirtina skirtingose socialinio žinojimo struktūrose. Straipsnyje aptariami Lietuvoje atliktų tyrimų duomenys, kurie galėtų būti priskiriami ekspertų ir gerai informuotų piliečių socialinio žinojimo tipams. Lietuvos socialinės įtraukties politikos ekspertai ir šioje srityje dirbantys specialistai, kurie atitinka gerai informuoto piliečio apibrėžimą, yra linkę sureikšminti griežtas taupymo priemones ir socialinės kontrolės didinimą.

Decreasing Prescribing Errors During Pediatric Emergencies: A Randomized Simulation Trial
Authors: Larose Guylaine , Levy Arielle , Bailey Benoit , Cummins-McManus Barbara , Lebel Denis , Gravel Jocelyn
Published: February 2017

OBJECTIVE:

To evaluate whether a clinical aid providing precalculated medication doses decreases prescribing errors among residents during pediatric simulated cardiopulmonary arrest and anaphylaxis.

METHODS:

A crossover randomized trial was conducted in a tertiary care hospital simulation center with residents rotating in the pediatric emergency department. The intervention was a reference book providing weight-based precalculated doses. The control group used a card providing milligram-per-kilogram doses. The primary outcome was the presence of a prescribing error, defined as a dose varying by ≥20% from the recommended dose or by incorrect route. Residents were involved in 2 sets of paired scenarios and were their own control group. Primary analysis was the difference in mean prescribing error proportions between both groups.

RESULTS:

Forty residents prescribed 1507 medications or defibrillations during 160 scenarios. The numbers of prescribing errors per 100 bolus medications or defibrillations were 5.1 (39 out of 762) and 7.5 (56 out of 745) for the intervention and control, respectively, a difference of 2.4 (95% confidence interval [CI], −0.1 to 5.0). However, the intervention was highly associated with lower risk of 10-fold error for bolus medications (odds ratio 0.27; 95% CI, 0.10 to 0.70). For medications administered by infusion, prescribing errors occurred in 3 out of 76 (4%) scenarios in the intervention group and 13 out of 76 (22.4%) in the control group, a difference of 13% (95% CI, 3 to 23).

CONCLUSIONS:

A clinical aid providing precalculated medication doses was not associated with a decrease in overall prescribing error rates but was highly associated with a lower risk of 10-fold error for bolus medications and for medications administered by continuous infusion.

Simulating queuing behaviour of pedestrians in subway stations
Authors: Zheng Xun , Li Hai-ying , Meng Ling-yun , Xu Xin-yue , Yang Yi-hui
Published: February 2017

The aim of this study was to simulate pedestrian movements in the queuing process in subway stations using microscopic simulation models. The queuing process was divided into two stages – walking and selecting a queue, and entering a queue and waiting in that queue. To represent the boundary of these two stages, a novel queuing line concept was developed. This queuing line dynamically changes with factors such as pedestrian preference, queue shape and queue length. Furthermore, two corresponding microscopic simulation models were developed to handle those two stages on the basis of the social force model and the queuing rule, respectively. Typically, the queuing rule is determined by the desired force, the impact of the nearest pedestrian ahead in the same direction and a self-stopping mechanism. Two examples – a ticket office and a security check in a subway station – were used to verify the validity of the proposed models.
A Zselic digitális lábnyomai. Webes és közösségimédia-kutatás a régió platformjairól és reprezentációjáról
Authors: Fehér Katalin
Published: February 2017

A Zselic digitális lábnyomát hálózatkutatási módszertannal vizsgáló projekt célja az volt, hogy összegezze, elemezze és felmutassa a régió már felépült azonosítóit, webes, közösségi és témahálózatait, illetve reprezentációit. Cél volt továbbá erre alapozva ajánlásokat megfogalmazni egy konstruktív, célzott üzenetekre épülő digitális identitás felépítéséhez, mely online eszközökkel támogatja a térség turizmusát, gazdaságát, kulturális és természeti értékeinek védelmét és közösségeinek komfortját.

A kutatás két alapkérdésre épül. Az első alapkérdés, hogy tartozik-e a Zselic régió digitális identitásához egységes platform-, adat- vagy reprezentációs azonosítókészlet. A második alapkérdés, hogy melyek azok az interaktív platformok, ahol a Zselic regionális digitális identitása reprezentálódik. Vizsgáltuk azokat az azonosító funkciókat, témahálózatokat és reprezentációkat, melyek a térség digitális identitását hosszabb távon meghatározzák. Vizsgáltuk továbbá azokat az interaktív, kezdeményező és újításokra nyitott megoldásokat is, melyek hálózatokat és közösségeket építenek, illetve erősítik a régió vonzerejét és életminőségét. A kutatás kevert mintavételi eljárással készült és megismételhető a tanulmány alapján. A gyorsan változó digitális környezetek és a folyamatosan frissülő tartalom- és adatfolyamok azonban különböző kimenetekhez vezethetnek. A kapott eredmények alapján a meglévő, jó keresési és találati előzményekkel bíró, tartalmilag és funkcionálisan összefoglaló jellegű webes csomópontok erősítése javasolt, valamint a régió közösségei integrált online felületekkel és hálózati összeköttetésekkel támogathatók. Emellett újítások bevezetése és a fiatalabb generációk platformjain való erősítés szükséges.
Revisiting the andean tropical glacier behavior during the Antarctic cold reversal
Authors: Jomelli V. , Martin L. , Blard P. H. , Favier V. , Vuillé M. , Ceballos J. L.
Published: February 2017

The sensitivity of tropical glaciers to paleoclimatic conditions that prevailed during the Antarctic cold reversal (ACR, ca. 14.5-12.9 ka) has been the subject of a wide debate. In 2014 a paper suggested that tropical glaciers responded very sensitively to the changing climate during the ACR (Jomelli et al., 2014). In this study, we reexamine the conclusions from this study by recalculating previous chronologies based on 226 10Be and 14 3He ages respectively, and using the most up-to date production rates for these cosmogenic nuclides in the Tropical Andes. 53 moraines from 25 glaciers were selected from the previous analysis provided by Jomelli et al. (2014) located in Colombia, Peru and Bolivia. We then focused on two distinct calculations. First we considered the oldest moraine and its uncertainty for every glacier representing the preserved evidence of the maximum glacier extents during the last deglaciation period, and binned the results into 5 distinct periods encompassing the Antarctic cold reversal and Younger Dryas (YD) chronozones: pre-ACR, ACR, ACR-YD, YD and post-YD respectively. Results revealed a predominance of pre-ACR and ACR ages, accounting for 60% of the glaciers. Second we counted the number of moraines per glacier according to the different groups. 21 moraines (40%) of the selected glaciers belong to the pre-ACR-ACR chronozones while 3 moraines only (5%) were dated to the YD and YD-Holocene groups. The rest was assigned to the ACR-YD. These results suggest that moraine records are a very good proxy to document the ACR signal in the Tropical Andes.
Impact of Partial‐Mouth Periodontal Examination Protocols on the Association Between Gingival Bleeding and Oral Health–Related Quality of Life in Adolescents
Authors: Ediani Machado Michely , Tomazoni Fernanda , Ruffo Ortiz Fernanda , Ardenghi Thiago Machado , Zanatta Fabricio Batistin
Published: February 2017

Background: It is not clear how using partial‐mouth periodontal examination (PMPE) protocols affects estimates of the association between gingival bleeding (GB) and oral health–related quality of life (OHRQoL). The aim of the present study is to assess impact of different PMPEs on the association between GB and OHRQoL in 12‐year‐old adolescents.

Methods: A total of 1,134 adolescents were evaluated for clinical and subjective variables. GB was determined by full‐mouth examination (FME) of six sites (disto‐buccal [DB], mid‐buccal [B], mesio‐buccal [MB], disto‐lingual [DL], mid‐lingual, and mesio‐lingual [ML]) and different PMPEs were calculated using a 15% cut‐off point: 1) full‐mouth (MB‐B‐DB/MB‐B‐DL); 2) two diagonal quadrants (six sites/MB‐B‐DB/MB‐B‐DL); 3) two randomly selected half‐mouth quadrants (six sites/MB‐B‐DB/ MB‐B‐DL/MB‐DB‐ML‐DL); and 4) the community periodontal index. OHRQoL was assessed using the Child Perceptions Questionnaire (CPQ11‐14). Adjusted negative binomial regression models were used to calculate the rate ratio of CPQ11‐14 scores for each PMPE.

Results: Adolescents with GB showed significantly poorer OHRQoL than their counterparts when FME was used. In contrast, more than half of PMPE protocols did not detect significant associations between GB and CPQ11‐14 scores in the adjusted analysis.

Conclusions: Using PMPE to assess GB in adolescents significantly affects associations with OHRQoL outcomes, depending on the protocol used. PMPEs that evaluated MB‐B‐DL sites of randomly selected half‐mouth quadrants (1 or 2 and 3 or 4) achieved results closer to those obtained with FME.
Social Networks and the Building of Learning Communities: An Experimental Study of a Social MOOC
Authors: De Lima Mariana , Zorrilla Marta Elena
Published: February 2017

This study aimed to analyze the student’s behaviour in relation to their degree of commitment, participation, and contribution in a MOOC based on a social learning approach. Interaction data was collected on the learning platform and in social networks, both of which were used in the third edition of a social MOOC course. This data was then studied via statistical methods and analysis of social networks. This study assumes that social communities would arise around the course, would remain over time, and that participants would even contribute with new proposals. The findings indicated that social learning communities are built and continue only while the course is open and while the teachers are involved in fostering participation. Although this study is limited, the design criteria of the course, the pedagogical model on which this is supported, and the methods applied for this analysis provide other researchers and educators with clues for better understand the dynamic process of social learning in social MOOCs.
Why Do Academics Use Academic Social Networking Sites?
Authors: Meishar-Tal Hagit , Pieterse Efrat
Published: February 2017

Academic social-networking sites (ASNS) such as Academia.edu and ResearchGate are becoming very popular among academics. These sites allow uploading academic articles, abstracts, and links to published articles; track demand for published articles, and engage in professional interaction. This study investigates the nature of the use and the perceived utility of the sites for academics. The study employs the Uses and Gratifications theory to analyze the use of ASNS.  A questionnaire was sent to all faculty members at three academic institutions. The findings indicate that researchers use ASNS mainly for consumption of information, slightly less for sharing of information, and very scantily for interaction with others. As for the gratifications that motivate users to visit ASNS, four main ones were found: self-promotion and ego-bolstering, acquisition of professional knowledge, belonging to a peer community, and interaction with peers.
Differences in the Students’ Perceptions on the Teaching of Neuroanatomy in a Medical Curriculum Organized by Disciplines and an Integrated Medical Curriculum
Authors: Arantes Mavilde , Barbosa Joselina , Ferreira Maria Amélia
Published: February 2017

Introduction: On the subject of curriculum reform, most European medical schools are moving away from an educational approach consisting of discipline-based courses to an integrated curriculum. The aim of this study was to compare, in the Faculty of Medicine of the University of Porto, Portugal, the teaching of neuroanatomy in a medical curriculum organized by disciplines and in an integrated medical curriculum.Material and Methods: Two hundred sixty one students who completed the Curricular Unit with a discipline-based approach (Neuroanatomy) and 202 students who completed it with an integrated approach (Morphophysiology of the Nervous System) were asked to complete a questionnaire on their perceptions about the Curricular Unit.Results: Our study showed that students of the Curricular Unit with a discipline-based approach had higher grades and evaluated it higher than students who followed the integrated approach. However, it also showed that students’ grades had a significant effect on the evaluation of the curricular unit, with students with higher grades evaluating higher than students with lower grades. Besides, the majority of the students of the Curricular Unit with an integrated approach appreciated this curriculum model and highlighted as a positive point the successful integration of contents covered in the three components of the curricular unit.Discussion: The curriculum reform led to the integration of neuroanatomy with other disciplines and resulted in a reduction of the teaching hours, a redefinition of the syllabus contents and the students’ learning objectives, the introduction of new educational methods and changes in the evaluation system.Conclusion: Our study could not prove conclusively the supremacy of one pedagogic approach to neuroanatomy over the other. Future initiatives to explore different pedagogical models in medical education are needed and should be of major concern to the medical faculty.
Behavior Changes and Gait Unsteadiness: The Value of Imaging and Prompt Neurosurgical Intervention
Authors: Costa Andreia , Marques-Matos Cláudia , Reis Carina , Carvalho Marta , Pinto Madalena
Published: February 2017

Cavernous angiomas are central nervous system malformations. Most common manifestations are seizures and acute focal neurological deficits. We present a case report of a seventy-one year-old man with a two-month history of behavior changes, attention deficit and indifference followed by gait unsteadiness. Neuropsychological evaluation showed severe cognitive impairment and executive dysfunction. Head computed tomography depicted a supraventricular hydrocephaly. Magnetic resonance imaging revealed a small hemorrhage, contiguous to a mesencephalic cavernous angioma, obstructing the Sylvius aqueduct, causing secondary hydrocephalus. Four months after endoscopic ventriculocisternostomy, neuropsychological evaluation showed improvement and the patient regained autonomy. Parenchyma cavernous angiomas causing direct hemorrhage and subsequent obstruction of the Sylvian aqueduct are uncommon. Sub-acute behavior and mental state abnormalities are rare first manifestations of cavernous angioma and requires high clinical suspicion for its correct diagnosis. Magnetic resonance imaging evaluation is crucial in the detection of such patients as prompt neurosurgical intervention may substantially improve cognitive function.

Special Issue on Multiaxis Control and Multitasking Machining
Authors: Nakamoto Keiichi ,   Tokyo University of Agriculture and Technology
Published: February 2017

Machine tools using numerical control (NC) devices are typical mechatronics products, and introducing them is a powerful way to automate plant production. NC machine tools in workshops meet the requirements of high accuracy and efficiency in the machining of a variety of parts and mold dies. Turning centers and machining centers are typical examples of such machine tools. Various cutting processes have been integrated in them to cope with the increase in machine parts that not only have complicated geometries but also must be made with high accuracy, in small quantities, and in a short machining time. In addition, turning and machining centers have been given multitasking capabilities, and the number of control axes has been increased so that complex products may be manufactured efficiently. Given that the strong attention and interest in multiaxis control and multitasking machine tools are rapidly increasing, it is fitting that the current state of the art of these tools and their practical and applicable technologies be presented. This special issue features 16 research articles – one review and 15 papers – related to the latest research results and practical case studies in multiaxis control and multitasking machining. Their subjects cover various advances in machine control, motion accuracy evaluation, machining error analysis, chatter vibration monitoring or suppression, trouble-free tool path generation, process planning, and new applications of the machine tools. We thank the authors for their contributions to this special issue, and we are sure that both non-specialists and specialists alike will find the information the authors provide both interesting and informative. Moreover, we deeply appreciate the reviewers for their incisive efforts. Without these contributions, this special issue could not have been realized. We truly hope that this special issue will trigger further research on multiaxis control and multitasking machining.
Evaluation Method for Behavior of Rotary Axis Around Motion Direction Changing
Authors: Nishiguchi Tadahiro ,   Nagano Prefectural Institute of Technology, Hasegawa Shogo , Sato Ryuta , Shirase Keiichi ,   Department of Industrial Engineering, Kobe University, Kobe, Japan
Published: February 2017

Several methods for evaluating the motion accuracy of the rotary axes in five-axis machining centers have been proposed till date. As it is known that particular motion errors exist around the motion direction changing points, it is important to evaluate the behavior of the rotary axes around these points. However, the influence of the motion error in the translational axes is included in the conventional evaluation results, as the translational axes reverse at the motion direction changing points about the rotary axes. In this study, an evaluation method which can assess the behavior of a rotary axis around motion direction changes by synchronous motion of translational and rotary axes is proposed. In this method, the direction of translational axes does not change when the motion direction of a rotary axis changes. A measurement test and actual cutting tests are carried out to clarify the influence of the behaviors of rotary axes on the motion trajectory and machined surface, caused by the change in the motion direction of the rotary axis. Simulations of the motion are also carried out to discuss the causes of inaccuracy.
A Robot Gripper in Polymeric Material for Solid Micro-Meso Parts
Authors: Aggogeri Francesco ,   Department of Mechanical and Industrial Engineering, University of Brescia, Avanzini Andrea , Borboni Alberto , Pandini Stefano
Published: February 2017

This paper proposes a robot gripper in polymeric material for solid micro-meso parts. The gripper is developed using a light-weight, highly deformable and low cost material, that allows elastic deformations. The proposed solution consists of a simple geometry, incorporating the complexity of the mechanical transmission in the non-linear high deformations of the flexible elements of the device. This choice permits to grip multi-sizes objects. The design approach focuses on Ludwick material model, that describes deformable materials with a nonlinear elastic behavior. The kinematics of the gripper is presented and the results are verified with the finite element analysis. Finally, the gripper was fabricated and validated through a set of experimetal tests. The obtained resulsts confirmed the theoretical and simultion models. The maximum opening and force of the gripping jaws are 1,500 μm and 155 mN, repsectively. Nevetheless further performances may be obtained using different geometrical choices developed in the kinematic analysis.
