Comments on “A new deep-water Astyris species (Buccinoidea: Columbellidae) from the southeastern Pacific” by Araya et al. 2016
Authors: SELLANES JAVIER
Published: March 2017

The aim of this note is to clarify some aspects posed by Araya et al. (2016) in the description of the columbellid gastropod Astyris atacamensis for northern Chile, and also to complement it for providing further insight on important ecological aspects of the genus Astyris in the SE Pacific. Araya et al. (2016) fill an important gap, describing a species that in my opinion is important in many aspects, yet, they fail in connecting this new species with previous work in which this taxon has been mentioned. Araya et al. (2016) indicate that the genus has not been previously reported for the SE Pacific; however, Levin et al. (2002a) already mention finding Astyris permodesta (Dall, 1890) off Callao, Perú (~12°S). Astyris permodesta, originally described for the coast of California, is currently accepted under the genus Alia (Monsecour 2015). Although we still cannot confirm, most probably future analysis will prove that A. permodesta reported for Perú by Levin et al. (2002a) corresponds indeed to the new species Astyris atacamensis. Future work should elucidate the definitive placement of this species in either Alia or Astyris, but hereafter I will indistinctly use Astyris.
Clarification of the type locality of the Curl-crested Aracari Pteroglossus beauharnaesii Wagler, 1832 (Aves: Ramphastidae)
Authors: COSTA THIAGO V. V. , PACHECO JOSÉ FERNANDO , SILVEIRA LUÍS FÁBIO
Published: March 2017

The Curl-crested Aracari Pteroglossus beauharnaesii Wagler, 1832 is one of the most remarkable species in the family Ramphastidae. Among other distinctive plumage traits, its modified curly, shiny black crown feathers are unique in the family and are modified to an extent not found in any other living bird species (Brush 1967; Short & Horne 2002). The crown feathers, along with the distinct white throat, were considered sufficient justification in the past to include the species in the monotypic genus Beauharnaisius Bonaparte; however, molecular studies have shown that it is embedded within the genus Pteroglossus Illiger, sister to P. bitorquatus (Hackett & Lehn 1997; Eberhard & Bermingham 2005; Pereira & Wajntal 2008). It is a southern Amazonian species, occurring in the lowlands of northern Peru, north and central Bolivia and western and central Amazonian Brazil, south of the Marañon-Solimões-Amazonas rivers (Short & Horne 2002).
Review of the subgenus Xizicus (Xizicus) Gorochov, 1993 (Orthoptera: Tettigoniidae: Meconematinae) from China
Authors: FENG JIYUAN , SHI FUMING , MAO SHAOLI
Published: March 2017

Gorochov (1993) erected the subgenus Xizicus (Xizicus), with the type species Xizicus (Xizicus) fascipes (Bey-Bienko, 1955). This subgenus is distinguished from the other subgenera of Xizicus by the following characters: male tenth abdominal tergite with a pair of contiguous posterior processes in the middle; subgenital plate simple, styli slender, located on the apices or subapices of lateral margins; posterior margin of female subgenital plate rounded.
Exploring Individual, Family, and Extrafamilial Factors Associated With Depression Among Elderly Residents of Care Settings
Authors: Hsiao Yi-Chen , Chen Chun-Yuan
Published: March 2017

This study investigated simultaneously the associations among individual, family, and extrafamilial factors and depression among elderly residents of care settings in Taiwan. The data for this study were obtained from the Vulnerability and Social Exclusion among Different Groups of Disadvantaged Elderly in an Aging Society: Phenomena and Strategies (1/2) project, which was conducted in Taipei City and Taipei County in 2007. We applied multiple regression procedures to a sample of 327 residents of care settings (48.3% women) who were mild physical impairment or physically independent and cognitively clear for determining factors associated with depression and their cumulative effects. We discovered that 24.5% of the residents were depressed. Physical mobility, number of chronic diseases, and self-assessed health status were significantly associated factors in all models. In the final model, we determined that one third of extrafamilial factors were significantly associated with depression, after controlling for all other variables. In addition, we observed an overall trend of increased mean scores of depression with an increase in the number of risk factors. The results imply that interventions aimed at preventing depression in elderly persons living in care settings, particularly persons with multiple risk conditions such as impaired physical mobility and medical comorbidities, should be designed to include extrafamilial elements. Establishing strong connections between elderly care setting residents and the institutional and neighborhood environments can help prevent depression.
Viscoelastic resonant responses of shear deformable imperfect microbeams
Authors: Farokhi Hamed , Ghayesh Mergen H
Published: March 2017

A viscoelastic model for the nonlinear analysis of the coupled transverse, longitudinal, and rotational oscillations of an imperfect shear deformable microbeam is developed, for the first time, based on the modified couple stress theory. An energy dissipation mechanism is developed via use of the Kelvin–Voigt internal energy dissipation mechanism. For the stress and deviatoric part of the symmetric couple stress tensors, the viscous components along with the corresponding work terms are obtained. The size-dependent elastic energy along with the kinetic energy of the viscoelastic microsystem is formulated in terms of the displacement field together with system geometric and physical parameters. The internal energy dissipation is developed via the work done by the viscous components of the stress and the deviatoric part of the symmetric couple stress tensors by means of the Kelvin–Voigt mechanism. These work and energy terms are inserted into Hamilton’s principle together with the work due to an external force in order to obtain three viscoelastically coupled equations governing the transverse, longitudinal, and rotational motions with cubic and quadratic nonlinear terms. A high-dimensional Galerkin approximation method is applied for all the three equations, yielding three sets of second-order coupled ordinary differential equations with cubic and quadratic nonlinearities. Upon application of a transformation, a continuation technique along with the backward differentiation formula (BDF) is employed in order to obtain the time-variant response of the system subject to a harmonic load. Special attention is paid to the effect of the Kelvin–Voigt type viscoelasticity on the system response in the presence of the length-scale parameter.
Correlates of Postpartum Maternal Functioning in a Low-Income Obstetric Population
Authors: Barkin Jennifer L. , McKeever Amy , Lian Brad , Wisniewski Stephen R.
Published: March 2017

BACKGROUND: Perinatal mental health has been characterized primarily via depression evaluation. However, there may be advantages to complementary assessment of postpartum functional status. OBJECTIVE: The purpose of this study was to examine sociodemographic and clinical factors associated with maternal functioning in low-income obstetrics patients. DESIGN: One hundred and twenty-eight women receiving postpartum obstetrical care at a large medical center in medically underserved, Middle Georgia were screened for depressive symptoms with the Edinburgh Postnatal Depression Scale. The women also completed the Barkin Index of Maternal Functioning and a sociodemographic survey. Multivariate analysis was performed to elucidate factors independently associated with maternal functioning. RESULTS: Higher Edinburgh Postnatal Depression Scale scores ( p < .0001) and being married ( p = .043) were associated with decreased maternal functioning. CONCLUSIONS: Health care providers should be cognizant of the relationship between postnatal depression and maternal functioning and its potential implications for family health.
Development of a Psycho-Educational Support Program for Individuals with Primary Progressive Aphasia and their Care-Partners
Authors: Morhardt Darby J , O’Hara Mary C , Zachrich Kristine , Wieneke Christina , Rogalski Emily J
Published: March 2017

Primary progressive aphasia is a language-based dementia that initially spares other cognitive domains; however, aphasia interferes with many life roles such as work and interpersonal relationships. Psycho-educational programs, such as support groups have been shown to be effective for persons with Alzheimer’s dementia; however, little is known regarding their effectiveness for persons with primary progressive aphasia. This paper describes the development of a program that offers support, education and activities for persons with primary progressive aphasia and their care-partners and its feasibility. Development and structure of pilot and formal intervention groups are described. Thematic analysis of both groups included the following themes: (1) coping with limitations and language decline; (2) dealing with increased dependency; (3) expressing resilience and making adaptations; (4) experiencing stigma (pilot group) and confronting stigma (intervention group); (5) experiencing self-confidence; and (6) feeling a sense of belonging. The knowledge gained from this process may be useful in designing programs for individuals with aphasic dementia and preserved insight. Evidence-based data from supportive interventions for persons with primary progressive aphasia and their care-partners are needed.
Terror, Territoriality, Temporality: Hypermedia Events in the Age of Islamic State
Authors: Kraidy Marwan M.
Published: March 2017

Considering the group that calls itself Islamic State (IS) as a “war machine,” an ever-shifting combination of humans and technology, this article articulates, from a Deleuzian perspective, terror, territoriality, and temporality as constitutive of events. It explores terrorism as a hypermedia event that resists conceptual containment in Dayan and Katz’s three categories of “contest,” “conquest,” or “coronation.” It builds on work that recognizes the globality of media events. The article uses the rise of IS to explore events as a peculiar articulation of space and time, and draws on the global “network-archive” that IS created (its digital footprint), the referentiality of which means that we experience IS depredations as one continuous “global event chain.” In this analysis, media events are a productive force that articulates territoriality and temporality through affect.
Run-time deployment and management of CoAP resources for the Internet of Things
Authors: Martín Cristian , Díaz Manuel , Rubio Bartolomé
Published: March 2017

The continuous growth of the Internet of Things in recent years has meant it is increasingly more present, as Internet of Things scenarios such as smart homes and smart cities become part of our everyday lives. The Internet of Things devices involved can be divided into two categories in most Internet of Things scenarios. The devices can constitute a black box with specific sensors which complicates their configuration, for example, wearable products. Other Internet of Things devices can be composed through configurable microcontrollers, enabling customizable environments to be designed. However, the necessary tools and knowledge for programming and configuring microcontrollers are not accessible to everyone. This article proposes a run-time deployment and management system through the Constrained Application Protocol that bridges the gap between end users and customizable environments. With our system, end users can incorporate new sensors or actuators in their installed microcontroller without having to access and program the microcontroller board. Rather, they can manage the resources of the Constrained Application Protocol servers through an accessible and transparent Web user interface.
A multipronged evidence-based approach to implement mHealth for underserved HIV-infected populations
Authors: Krishnan Archana , Cravero Claire
Published: March 2017

Mobile technology shows great promise in resource-limited settings due to its low cost and pervasive nature. Early evidence-based studies have shown robust support for mHealth interventions implemented among people living with HIV (PLWH); however, this type of inquiry is lacking amongst the most vulnerable groups of PLWH such as men who have sex with men (MSM), prisoners, and those facing substance use disorders (SUDS) and structural instabilities. These populations face barriers more profound than the general PLWH population including social stigma and discrimination. In response to the lack of rigorous evaluation of mHealth implementation and the tremendous potential for mHealth tools in underserved PLWH, we propose a 3-pronged approach in rooting mHealth tools using evidence-based methodology—(a) assessing mHealth feasibility and accessibility through descriptive studies, (b) conducting pilot projects testing mHealth tools, and (c) integrating mHealth tools into existing large-scale studies. The set of research steps proffered here aims to build a solid body of evidence on mHealth interventions among underserved populations and the health conditions that disproportionately affect them.

Authors: Li James Weiquan , Ang Tiing Leong , Kam Jia Wen , Kwek Andrew Boon Eu , Teo Eng Kiong
Published: March 2017

Background

There is no consensus on what constitutes adequate training for needle knife precut sphincterotomy.

Objective

The purpose of this study was to determine the number of procedures required before effective and safe precut sphincterotomy can be achieved.

Methods

This retrospective study examined the cumulative experience of a single endoscopist from January 2006–December 2015. Precut sphincterotomy success and complication rates were analyzed as a function of number of procedures performed. Acceptable success and complication rates were defined as 85% and 10% respectively. A one‐sided binomial test was used to test success and complication rates of every 25 precut sphincterotomies performed.

Results

The index endoscopic retrograde cholangiopancreatography was successful in 141/158 (89.2%) patients who underwent precut sphincterotomy. This increased to 148/158 (93.7%) when endoscopic retrograde cholangiopancreatography was repeated on another day. Six precut sphincterotomies were required to achieve an 85% success probability. This was maintained consistently above 85% after 13 precuts, and was significantly higher (91.2%; p  = 0.029) than 85% at the 125th precut. Bleeding and pancreatitis developed in 2/158 (1.3%) and 5/158 (3.2%). Probability of either complications remained below 5% after 50 precuts. No perforation occurred.

Conclusion

At least 13 precut sphincterotomies were required to achieve a sustained success rate greater than 85%. The probability of bleeding or pancreatitis was less than 5% after 50 precut sphincterotomies.
Conscientious and proud but challenged as a stranger: Immigrant nurses’ perceptions and descriptions of the Norwegian healthcare system
Authors: Dahl Kari , Dahlen Kirsti Jæger , Larsen Kristian , Lohne Vibeke
Published: March 2017

The number of nurses in Norway educated outside of the European Union is increasing. The purpose of this study is to explore how immigrant nurses, all educated as nurses in their home countries, experience working as a nurse in Norway. The study has a qualitative design with a social constructivist perspective and is based on written narratives from open-ended questions representing 144 nurses from 18 different counties. Two main themes based on patterns from the participants’ text were constructed: ‘conscientious and proud as nurses’ and ‘impressed but challenged as strangers’. The findings are discussed in relation to research in cultural understanding. Immigrant nurses contribute with important knowledge and cultural competence to nursing and the Norwegian healthcare system, but there are also challenges. More knowledge is needed in education, research and in individual institutions about the contributions and challenges immigrant nurses bring with them.

The First Ones: Three Studies on First-Generation College Students
Authors: Longwell-Grice Rob , Adsitt Nicole Zervas , Mullins Kathleen , Serrata William
Published: March 2017

The findings from 3 qualitative research studies related to first-generation college students show themes of strains in family relationships and lack of practical familial support. One study reveals sources of resiliency and persistence of graduate students; another explores sense of belonging for undergraduates attending 3 types of private institutions; the final study features concerns of Latinos at a 2-year college. Together these studies show that creation of a student identity creates unique challenges for those transitioning into bicultural persons. Advisors who understand students coping with changing family status while attending college can proactively guide them toward the degrees they seek. Furthermore, administrators should provide programs and professional development that help advisors address the complex issues facing first-generation students.

Negócios sociais: a percepção, a consciência e o grau de interesse pelo tema para os alunos de graduação em Administração
Authors: Jahchan Amanda Leme , Comini Graziella Maria , D'Amario Edison Quirino
Published: March 2017

Este estudo teve como objetivo entender a percepção e o conhecimento dos alunos de administração da FEA-USP sobre o tema negócios sociais. Negócios Sociais são empreendimentos que alinham a lógica de mercado e a lógica social, ou seja, buscam a autossustentação pela venda de produtos e serviços juntamente com a geração de valor social. Considerou-se importante mapear até que ponto alunos de administração têm interesse nesse tipo de organização. Realizou-se um levantamento quantitativo com uma amostra de 515 alunos do curso de graduação em Administração de Empresas da FEA USP. Dentre os achados, destacaram-se: a maioria acredita que seu conhecimento é básico; tem alto interesse e acha importante; nunca participou de atividades extracurriculares; depende de recomendação de amigos e parentes para entender e fazer parte; não conhece o tema a fundo, mas faz muitas associações corretas de conceitos; e acredita que as maiores dificuldades dos empreendimentos sociais são autossustentação financeira e atração de investidores. A principal contribuição deste estudo está na observação que há uma lacuna no ensino de administração na formação de gestores para empreendimentos sociais.
‘Delivering for the Fancy as Well as the Shabby’ Amsterdam’s Post-war Utopia of Urban Diversity
Authors: Verlaan Tim
Published: March 2017

Over the last few years, Amsterdam’s inner city has seen a rapiddecrease in quality of life. Long-time residents and established retailers are increasingly giving way to the needs and demands of mass tourism.The advent of low-cost airliners, the rise of a global middle class and the uncontrollable spread of apartment sharing have put the affordability of central districts at risk, threatening the future of a socially and functionally mixed inner city. Most local residents respond with feelings of resignation, some of them even catering to the wishes of international visitors by renting out their flats using platforms such as Airbnb. Looking at these developments of gentrification and displacement, it seems as if Amsterdam has forgotten how its beloved inner city was once saved from similar threats.
New directions for the dense city: Moshe Safdie in Singapore
Authors: Bischeri Cecilia , Micheli Silvia
Published: March 2017

In 1965, Singapore declared its independence and initiated a process of modernisation aiming to erase any evidence of its colonial past. Thedevelopmentalist orientation of Singapore, as Rem Koolhaas defined it, together with the formula “displace, destroy, replace,” became the theoretical instruments used to implement the urban vision for the future city. Singapore has thus become the contemporary urban laboratory of the Asia Pacific Region and due to its limited area for construction, turned into an experimental epicentre in the field of dense dwelling. A protagonist of this experimentation has been the Israeli/Canadian architect Moshe Safdie, designer of the Integrated resort casino Marina Bay Sands (2010), an exemplary feature of Singapore’s drive for development. This paper focuses on Safdie’s theoretical work, casting light on the ideological shift from his early modern residential project Habitat‘67, built during the Expo in Montreal (Canada) in 1967, to the contemporary residential complex Sky Habitat, completed in 2015 in Singapore. While Habitat’67 represented the manifesto of Safdie’s social utopia, envisaging itself as a prototypical residential component of the future city, Sky Habitat is a private gated community, which targets an upper-class market. And yet, Safdie’s two projects, distant in time and social ideals, display comparable strategies, as the use of similar architectural solutions and the permanence of urban modern utopian principles. These strategies underpin two other projects designed recently by Safdie in China: the Golden Dream Bay in Qinhuangdao (2016) and Chongqing Chaotianmen (design phase), which propose further elaboration of Sky Habitat’s urban principles. This paper will investigate how utopian urban strategies elaborated during the Modern period and advanced and tested in the 1960s and 1970s, have become material of experimentation for new forms of living in the congested 21st century city, evolving the concept of urban density in “the city that could be”.

Die High-Performance-Plattform New STN – eine neue Recherchedimension
Authors: Bolle Babett
Published: March 2017

Patentinformationen spielen im Innovationsprozess eine entscheidende Rolle. Alle innovativen Unternehmen müssen, um ihr Investitionsrisiko zu minimieren und abzusichern, verlässliche Informationen zum Stand der Technik zu den Wettbewerbern und dem Marktumfeld recherchieren. Informations- Services im Patentbereich müssen daher höchsten Ansprüchen bei der Präzision und Zielgenauigkeit der Suche, ebenso wie bei der Aktualität und Vollständigkeit der Daten gerecht werden. Mit der neuen STN-Plattform hat FIZ Karlsruhe in Kooperation mit CAS (Chemical Abstract Service) eine neue Dimension bei der Informations- und Patentrecherche geöffnet. Ein intuitives Nutzerinterface für Informationsexperten, branchenführende Performance und Workflowoptimierung sind die Markenzeichen der neuen STN-Plattform. Die neue STN-Plattform wurde 2012, zunächst in einer Beta-Version, erstmals der Öffentlichkeit vorgestellt. Seit 2013 läuft die neue Plattform als Vollversion und wird kontinuierlich erweitert. Die neue STN-Plattform soll das klassische STN in Zukunft ablösen. Zurzeit werden beide STN Systeme parallel betrieben.
Für eine informationswissenschaftliche Aufwertung von Rezensionen

Published: March 2017

Der Autor plädiert dafür, wissenschaftliche Rezensionen stärker als Gegenstand informationswissenschaftlicher Forschung und Praxis in den Blick zu nehmen. Verabschiedet man sich von der Vorstellung, dass dokumentarische Objektivität durch die Minimierung der Subjektivität des Abstracters zu erreichen sei, und begreift man (intellektuelles) Abstracting als produktiven Prozess, der wesentlich von den sozialen Regeln der scientific community bestimmt ist, so lässt sich erkennen, dass das Interesse an wissenschaftlichen Rezensionen als spezifischer Textsorte Teil eines gruppenspezifischen Informationsverhaltens ist.

Published: March 2017

Dieser Artikel stellt ein konzeptionelles Metadatenmodell vor, das auf Records verschiedener Medientypen anwendbar ist. Organisationen, die im Zuge ihrer Tätigkeit regelmäßig sowohl textbasierte als auch audiovisuelle Records erstellen, haben beide Medien im Sinne des Records Management zu verwalten. Dazu sind Metadaten, einschließlich der des zentralen Ordnungssystems für Records, ein Hauptwerkzeug. Inspiriert durch medienübergreifende, auf gemeinsamen Zugriff ausgerichtete Metadatenmodelle, wird ein neues Modell vorgeschlagen. Es kombiniert die hierarchische Abstraktion der existierenden Modelle mit den Prinzipien des Records Management. Das Modell kann Organisationen dabei helfen, Entscheidungen über Metadaten für ihre Records zu treffen.

Published: March 2017

Present paper reports removal of radiocesium from low level waste using a modified sorbent (13X-CFC) prepared by in-situ precipitation of potassium copper hexacyanoferrate(II) inside the macropores of a synthetic zeolite. The Cs exchange isotherm of the sorbent is established and it found to follow Fruendlich absorption isotherm equation. It is varified that presence of hexacyanoferrate on zeolite facilitates rapid Cs uptake performance. This is further confirmed in laboratory scale column tests, wherein excellent Cs removal performance from low level waste simulant was observed even at higher flow rates (40 bed volumes per hour). The utility of the sorbent is established through successful demonstration in a pilot scale (50 L) trial with almost complete removal of 137Cs from more than 14,000 bed volumes of actual low level waste. The sorbent, owing to its low cost and excellent 137Cs removal performance, is expected to find application in treatment of very low active waste streams.
Synthesis, radiolabeling and biological evaluation of [125I]-1-[2-(benzylthio)ethyl]-4-(5-iodo-2-methoxyphenyl)piperazine as a new 5-HT1A receptor ligand
Authors: Narimani Ali , Sadeghzadeh Masoud , Kurdtabar Mehran
Published: March 2017

5-HT1A receptors have been implicated in the pathogenesis of a wide variety of disorders related to the serotonin receptors. WAY100635 is a well-known high affinity 5-HT1A receptor antagonist. Many 11C and 18F radiolabeled derivatives and its radioiodinated analogues have been reported as imaging agents for 5-HT1A receptors. In this regard, the synthesis, radiolabeling and biological evaluation of a new 5-HT1A receptor radioligand, [125I]-1-(2-(benzylthio)ethyl)-4-(5-iodo-2-methoxyphenyl)piperazine ([125I]-BTE-IMPP), are described. Radioiodination of this newly synthesized compound was done by the direct aromatic electrophilic substitution via Iodo-Gen method. Radiochemical yield and radiochemical purity determined by TLC and RTLC were >70% and >95%, respectively. Biodistribution studies of [125I]-BTE-IMPP in rats displayed relatively high uptake in hippocampus (Hip) and low uptake in cerebellum (Cer). The level of the radiotracer uptake was over threefold higher in hippocampus than in cerebellum at 30 min post-injection. Moreover, the brain to blood uptake ratio and the blocking studies results indicated prolonged retention of the radiotracer and relatively good specific binding to 5-HT1A receptor. These findings strongly suggest that [125I]-BTE-IMPP could be a good candidate as an in vivo marker for pharmacological study of 5-HT1A receptors in animal models.
Weitere Überlegungen zu den Voraussetzungen und Folgen des Perikleischen Bürgerrechtsgesetzes: Naturalisierung und Epigamie im Klassischen Athen
Authors: Coşkun Altay
Published: March 2017

This study departs from the recent re-assessment of Pericles’ Citizenship Law: it made descent from two citizen parents a necessary requirement for citizenship, without allowing for any deadlines or exemptions. Behind this background, at first all traces of potential exceptions that might have been formulated in the law are considered - and rejected. However, special regulations would still have been necessary, if one posits that the assembly of the people had been used to convey either citizenship to individuals or epigamia to foreign poleis prior to the mid-5th century BC. In fact, two examples of early naturalization in Athens have been adduced in scholarly literature: those of Menon of Pharsalus and Polygnotus of Thasus. While these cases are in conflict with the aforementioned interpretation of Pericles’ Citizenship Law, they do not stand up to closer inspection. Likewise, the existence of any positive right to legitimate intermarriage beyond the boundaries of the polis community cannot be ascertained for that early period. It will rather be shown that the assembly bothered to convey citizenship or epigamia only as a result of the radically narrow definition of citizenship by Pericles.
Macht, Memoria und Monumente: Marius, Sulla und der Kampf um den öffentlichen Raum
Authors: Stein-Hölkeskamp Elke
Published: March 2017

During the first decades of the first century BC, the political situation in Rome was deeply affected by the rivalry between C. Marius and L. Cornelius Sulla. This increasingly bitter rivalry extended to a traditionally important realm of Republican aristocratic self-fashioning, namely the medium of victory and/or honorific monuments displayed in public. This paper offers a detailed account of the effective self-advertising by monuments and above all the systematic destruction of those of his rival Marius, by which Sulla in particular radically changed and redefined the established rules of cultivating and perpetuating the collective memory.
DEKARTIŠKI SEMANTINIO NATŪRALIZMO BRUOŽAI
Authors: Gilaitis Mindaugas
Published: March 2017

Straipsnyje analizuojamos semantinio natūralizmo formos, vyraujančios šiuolaikinėje analitinėje filosofijoje, teorinės prielaidos. Siekiama parodyti, kad nors semantinis natūralizmas paprastai yra grindžiamas ontologinio bei epistemologinio natūralizmo idėjomis ir vystomas semantinio eksternalizmo pagrindu, ši fundamentinės semantikos koncepcija suponuoja internalistines prielaidas ir dėl to turėtų būti vertinama kaip dekartiška. Pasiremiant trinare „intencionalumo problemos“ interpretacija, įvardijamos semantinio natūralizmo suponuojamos teorijos bei jų sąsajos. Dekartiški suponuojamų teorijų – taigi ir analizuojamos semantinio natūralizmo formos – aspektai atskleidžiami nagrinėjant Hilary Putnamo semantinio eksternalizmo versiją.
MORALĖS RIBOS IR PARIBIAI: NUO BIOETIKOS IKI GYVŪNŲ TEISIŲ
Authors: Bartkienė Aistė
Published: March 2017

Straipsnyje tiriamas rūpesčio kitu konceptas, kartu parodant, kad supratimas, kokie poreikiai ir kieno teisės yra verti dėmesio, priklauso nuo kultūrinės terpės. „Kitas“ šiame straipsnyje suprantamas iš pačios plačiausios perspektyvos, kuri apima ne tik žmonės, bet ir gyvūnus, taip pat kitus biotos dalyvius. Atsiremiant į rūpesčio etikos teorijas išryškinama, kaip emocinė dimensija ir dėmesys egzistuojančioms rūpesčio kitais praktikoms gali praturtinti tradicinę bioetinę perspektyvą, išplečiant jos ribas tiek, kad ji apimtų visus žalą galinčius patirti gyvus organizmus. Tvirtinama, kad pagarbus rūpestis gyvūnais ir mus supančia aplinka yra įprotis, ne tik ugdomas nuo vaikystės, bet ir atitinkantis konkrečioje kultūroje egzistuojančias vertybes. Remiantis žymiausiomis aplinkosaugos ir gyvūnų etikos teorijomis atskleidžiama, kaip kinta vertybinis požiūris į gyvūnus bei aplinką. Šis kismas gali būti iliustruotas B. Rollino teiginiu, kad nėra jokio moraliai reikšmingo žmonių ir gyvūnų skirtumo, kuriuo remiantis gyvūnai negalėtų būti įtraukiami į etinio rūpesčio lauką. Straipsnyje siūloma moralės sferą bioetikoje išplėsti remiantis N. Noddings pasiūlytu rūpesčio konceptu, taip į šią sferą įtraukiant ne tik nežmogiškuosius gyvūnus, bet ir visą mūsų aplinką.
PLATONO KALBOS TEORIJA: KOSMO IR LOGO IZOMORFIZMAS TIMAJUJE
Authors: Pleshkov Alexey
Published: March 2017

Straipsnyje per Timajaus metafizikos prizmę aptariama Platono kalbos teorija. Teigiama, kad Platono kalbos filosofijos tariamas prieštaringumas kyla iš dvilypės kalbos prigimties ir kad Platono Timajuje pasiūlyta metafizinė schema gali nuskaidrinti jo nuoseklią kalbos teoriją. Timajo kalbos ir metafizikos izomorfizmas numato, kad (1) žodžiai ir materialieji elementai atitinkamai turi savo reikšmę ir prigimtį; (2) jie gali būti redukuoti į begalinę amorfinių garsų įvairovę; (3) dalyvavimas tiesoje įmanomas tik pasakojimo ir visatos lygmeniu. Pagal šią schemą, visata (κόσμος), kaip ir bet kuri kalba (λόγος), gali būti paaiškinta per redukciją į sudarančius elementus, tačiau tai tebus būtinas aiškinimas. Platonui tikrasis kosmo ir logo supratimas įmanomas tik koherentiško visumos vienumo lygmeniu, geriausiai reprezentuojančiu idealią paradigmą.
KODĖL ARISTOTELIS NESVARSTĖ TUŠČIŲ TERMINŲ PROBLEMOS?
Authors: Pabijutaitė Živilė
Published: March 2017

Straipsnio objektas yra teiginių su tuščiais terminais aristoteliškajame loginiame kvadrate analizė. Moderniojoje logikoje vyrauja nuostata, jog teiginiai su tuščiais terminais yra neteisėto egzistavimo importo (undue existential import) priežastis – siekiant jo išvengti, atsisakyta priešingumo, popriešingumo ir pavaldumo ryšių. Teiginių su tuščiais terminais problema straipsnyje pristatoma paradokso pavidalu: 1) teiginiai su terminais, neturinčiais referento, funkcionuoja loginiame kvadrate; 2) dalinis teiginys O su tuščiu terminu negali būti teisingas (dėl egzistavimo importo); 3) dalinis teiginys O su tuščiu terminu yra teisingas (dėl loginio kvadrato ryšių). Aptarus kitus pagrindinius paradokso sprendimo būdus, įrodinėjama, jog tradicinėje Aristotelio logikoje nei bendriesiems, nei daliniams teiginiams nebuvo būdingas egzistavimo importas – taigi, atmetama antroji prielaida. Sprendimas pristatomas kaip modifikuota tradicinės kvadrato interpretacijos versija: sutikdami su pagrindine jos teze, kad Aristotelio logikoje terminai nebuvo „tušti“ šiuolaikine prasme ir todėl teiginiams su tokiais terminais galioja tie patys principai kaip ir bet kuriems kitiems, nemanome, jog jungtis „yra“ išreiškia bet kokio pobūdžio egzistavimą, ir klausimą apie objektų egzistavimą paliekame už aristoteliškojo loginio kvadrato ribų. Siūlomas paradokso Aristotelio sistemoje sprendimas grindžiamas pastarųjų metų bandymais interpretuoti terminų logiką intensiniu pagrindu.

DOSIS DEBIDO A LA INCORPORACIÓN POR INGESTIÓN DE EMISORES BETA PUROS
Authors: Ocampo-Ramos Juan Camilo , Puerta-Ortiz Jorge Anselmo , Morales Javier
Published: March 2017

El cálculo de dosis debido a la incorporación de radionúclidos se realiza en función de los coeficientes de dosis equivalente comprometida h(50) y dosis efectiva comprometida e(50). En este trabajo se calculan estos coeficientes de dosis para la ingestión única de 3H, 14C, 32P, 35S utilizando los valores de las fracciones de absorción específicas (SAF) del phantom computacional masculino de referencia de la ICRP(International Commission on Radiological Protection). Se usó además el modelo del tracto alimentario humano, HATM, para la determinación del número total de desintegraciones (Us) y la metodología de cálculo de las nuevas recomendaciones del ICRP dadas en la publicación 103. En general se encontró que los coeficientes de dosis equivalente comprometida para la mayoría de órganos presentan relativamente pocas diferencias, con excepción de algunos órganos como las paredes del estómago, el colon y la vejiga, además se encontró que existen diferencias significativas en las dosis de la medula ósea (RBM) y la superficie ósea (BS) para el caso particular del 32P.
VALIDACIÓN DE UN MÉTODO PARA EL ANÁLISIS DE RESIDUALIDAD DE PLAGUICIDAS EN GULUPA (Passiflora edulis f. edulis)
Authors: Olivo-Taborda Sara Juliana , Echeverry-Ruiz Juan David
Published: March 2017

La gulupa perteneciente a la familia Passifloraceae, es nativa del trópico americano, y se caracteriza por su exótico y distintivo aroma, cualidad que la hace atractiva para el mercado europeo, para lo cual debe de cumplir estándares de inocuidad sanitaria. Para ello, se evaluó un método para el análisis simultáneo de residualidad de parathion-methyl, malathion, deltamethrina y chlorothalonil en esta matriz. Se aplicó la técnica de QuEChERS, siguiendo una modificación del protocolo EN 15662, formado por tres etapas, la primera, consiste en una extracción con acetonitrilo (MeCN) que incluye un proceso de precipitación salina de la muestra en medio acuoso. En el segundo paso, se realiza una limpieza utilizando diversos sorbentes para remover la mayoría de componentes coextraídos con los analitos, y por último se realiza el análisis instrumental empleando la cromatografía gaseosa. En el análisis de linealidad se obtuvieron correlaciones de 0,9991; 0,9998 y 0,9992 para parathion-methyl, malatihon y deltametrina respectivamente; que cumplieron las pruebas de significancia, pues chlorothalonil no cumplió con los parámetros requeridos para la validación. Se lograron límites de cuantificación de 0,035 mg/kg para parathion-methyl y 0,02 mg/kg para los otros dos compuestos validados con estimaciones de incertidumbre menores al 50%. Se cumplieron los criterios de precisión y exactitud establecidos en SANCO 12571, 2013, logrando una validación exitosa
PRESENCIA DE Wolbachia y Leishmania EN UNA POBLACION DE Lutzomyia evansi PRESENTE EN LA COSTA CARIBE DE COLOMBIA

Published: March 2017

Lutzomyia evansi es importante en salud pública por su participación en la trasmisión de la leishmaniasis visceral y cutánea en la costa caribe de Colombia. Diversos estudios se han desarrollado sobre la poblaciones naturales de Lutzomyia evansi, sin embargo pocos estudios han explorado en profundidad la detección de microorganismos simbióticos (ej. Wolbachia) y de manera simultánea la presencia de Leishmania sp.. El endosimbionte Wolbachia ha sido propuesto en la actualidad como control biológico de insectos vectores de diversas enfermedades tropicales. En el presente estudio el ADN de tres especies del género Lutzomyia colectadas en el municipio de Ovejas (Departamento de Sucre) fue evaluado para detectar la infección natural por la bacteria Wolbachia y la presencia de parásitos del género Leishmania. El ADN total de 176 individuos adultos y 34 inmaduros (larvas y pupas) de Lu. evansi, fue utilizado para evaluar la detección de Wolbachia mediante amplificación por PCR del gen WSP (Proteína Mayor de la Superficie de Wolbachia) y la infección por Leishmania mediante amplificación por PCR de segmentos de los genes HPSN70 (Proteína de Choque Térmico). Se encontró un grupo de machos infectado de forma natural por Wolbachia y nueve grupos de hembras con infección natural por Leishmania, todos pertenecientes a Lutzomyia evansi. El análisis filogenético de la secuencia del gen WSP de Wolbachia indica la ubicación de la cepa detectada dentro del supergrupo B (haplogrupo wLeva) y su relación con haplotipos previamente reportados de Lutzomyia evansi y Lutzomya dubitans. Una región de 418 pb del gen HSP-70N fue secuenciada y mostró similaridad con secuencias de Leishmania luego de realizar el análisis en BlastN. Se confirma la presencia de Wolbachia en poblaciones silvestres de machos de L. evansi y la infección natural por Leishmania spp. en hembras de la misma especie cuya infección por Wolbachia resulto negativa.
LOS ELEMENTOS BÁSICOS PARA LA FORMULACIÓN DE POLÍTICAS CIENTÍFICAS, TECNOLÓGICAS Y DE INNOVACIÓN PARA LA COHESIÓN SOCIAL. UNA VISIÓN CTS
Authors: Viales Hurtado Ronny
Published: March 2017

En este artículo se discuten algunos elementos básicos para la formulación de políticascientíficas, en general, para la cohesión social, desde una perspectiva de Ciencia,Tecnología y Sociedad (CTS). Se toma en cuenta la necesidad de participación de actoresestratégicos y de actores emergentes, los cuales deben integrar tanto a las autoridadespolíticas y científicas tradicionales como a la sociedad civil; así como, el giro deliberativoque puede coadyuvar a superar el déficit democrático en materia de políticas científicas.Se pondrá énfasis en los elementos de contexto y en la fase de percepción y definición delproblema de política pública, según el planteamiento de Joan Subirats y se presentará unapropuesta inicial para la participación en la formulación de políticas científicas.
