Konflik dan resolusi konflik: Pendekatan analytical hierarchy process dalam konflik pertanahan di Urutsewu, Kebumen
Authors: Susanto Susanto
Published: July 2019

Artikel ini bertujuan untuk mencari alternatif dan model penyelesaian konflik pertanahan di Urutsewu Kebumen dengan menggunakan pendekatan Analytical Hierarchy Process (AHP). Konflik ini merupakan manifestasi dari persepsi dan preferensi yang berbeda yang terjadi pada pihak-pihak yang berkonflik. Hak dan kepemilikan tanah adalah penyebab utama konflik antara masyarakat Urutsewu dan TNI Angkatan Darat. Resolusi konflik alternatif diperlukan oleh orang-orang yang terlibat dalam konflik Urutsewu. Dalam menguraikan data, tulisan ini menggunakan pendekatan campuran sekuensial yang menekankan pada pendekatan kuantitatif dan kualitatif. Hasilnya menemukan bahwa alternatif resolusi berupa negosiasi dengan masing-masing pihak berhasil mencegah konflik semakin terbuka. Selain itu, persepsi masyarakat mengatakan bahwa mediasi adalah strategi yang baik untuk meredakan konflik juga mencari solusi atas persoalan yang terjadi di Urutsewu. Tidak itu saja, resolusi konflik juga harus menggunakan pendekatan yang demokratis, salah satunya dengan mengubah status tanah yang menjadi akar konflik dari state property menjadi common property.

Background

In a generalist laboratory, the integration of the data obtained from hematology analyzers (HAs) with those from multiparametric flow cytometry (FMC) could increase the specificity and sensitivity of first level screening to identify the pathological samples. The aim of this study was to perform a preliminary evaluation of a new simple hybrid method (HM). The method was obtained by integration between HAs reagents into FCM, with a basic monoclonal antibodies panel for the leukocytes differential count.

Methods

Eighty-one peripheral blood samples, collected in K3EDTA tubes, were analyzed by XN-module, and CyFlow Space System, using both standard MoAbs and HM method analysis, and with the optical microscopy (OM). Within-run imprecision was carried out using normal samples, the carryover was evaluated, data comparison was performed with Passing-Bablok regression and Bland-Altman plots.

Results

The within-run imprecision of HM methods ranged between 1.4% for neutrophils (NE) and 10.1% for monocytes (MO) always equal or lower to the OM. The comparison between HM methods vs. OM shows Passing-Bablok regression slopes comprised between 0.83 for lymphocyte (LY) and 1.14 for MO, whilst the intercepts ranged between −0.18 for NE and 0.25 for LY. Bland-Altman relative bias was comprised between −12.43% for NE, and 19.77% for eosinophils. In all 11 pathological samples the agreement between the methods was 100%.

Conclusions

The new hybrid method generates a leukocytes differential count suitable for routine clinical use and it is also useful for identifying morphological abnormalities with a reduction in cost and improvement of screening for first level hematology workflow.
A one-step incubation ELISA kit for rapid determination of dibutyl phthalate in water, beverage and liquor
Authors: Sun Quing , Chen Yanli , Li Fuxue , Jia Minghong , Shi Guoqing
Published: July 2019

A one-step incubation ELISA kit based on monoclonal antibody against dibutyl phthalate (DBP) was developed. After optimizing concentrations of coating antigen, antibody and composition of the assay buffer, an inhibition curve was plotted. The IC50 is 29.6 ng·mL-1, and the detection limit for DBP is 3.6 ng·mL-1. Compared with other ELISA methods, this ELISA kit had a simpler sample preparation, costed less time for detection and could detect more types of sample. The recoveries of DBP in water, beverage and liquor samples were range from 78% to 110.4%, the range of coefficient of variations is 7.7-15.3%. The cross reactivity was very low (&1%) except that for butyl benzyl phthalate (3.9%) and the di-isobutyl phthalate (12.5%). The detection results in liquor showed good correlation with those from GC-MS. All data above indicated that this kit could be used as the fast and high-throughput screening of DBP in water, beverage and liquor.
Nominal agreement in the interlanguage of Dutch L2 learners of Spanish

Inflectional morphology causes persistent difficulties for second language (L2) learners (Montrul, Silvina & Kim Potowski. 2007. Command of gender agreement in school-age Spanish-English bilingual children. International Journal of Bilingualism 11(3). 301–328; Montrul, Silvina, Israel de la Fuente, Justin Davidson & Rebecca Foote. 2013. The role of experience in the acquisition and production of diminutives and gender in Spanish: Evidence from L2 learners and heritage speakers. Second Language Research 29(1). 87–118). Learners operate with a default gender value, and overgeneralize the masculine forms of determiners and modifiers (White, Lydia, Elena Valenzuela, Martyna Kozlowska-Macgregor & Ingrid Leung. 2004. Gender and number agreement in nonnative Spanish. Applied Psycholinguistics 25(1). 105–133; Schlig 2003). 111 essays written were collected containing 799 correct uses and 281 errors from Dutch students whose written ability in Spanish is A2 (Common European Framework). The results show that singular masculine nominal agreement marking at the determiner is significantly better produced by Dutch L2 learners of Spanish than when the marking of nominal agreement is plural, feminine or at the adjective. This study corroborates the previous results where learners operate with a default gender value and overgeneralize the masculine forms of determiners. Also these results show that L2 learners of Spanish are significantly less accurate in gender agreement with adjectives than with determiners.
Bidirectional MDRZ Downstream and NRZ OOK Upstream SS-WDM RoFSO Communication System
Authors: Magidi S. , Jabeena A.
Published: July 2019

A cost-effective spectrum sliced wavelength division multiplexing radio over free space (SS-WDM RoFSO) full duplex communication system architecture has been proposed and analyzed. For the downlink, a 10 Gbits/s high spectrally efficient and amplitude maintaining modified duobinary return to zero (MDRZ) modulated the filtered slices from the light source. The free space optical (FSO) channel was modeled by the well-known Gamma-Gamma model and was further subjected to moderate rain attenuation conditions. Four FSO transceivers were used to mitigate against laser beam scintillation, geometrical losses and rain attenuation. For uplink, a reflective semiconductor optical amplifier (RSOA) was used both as a modulator and an amplifier. Its amplitude squeezing effect was used to erase the information in the MDRZ modulated downstream seeding wavelength for uplink transmission of 10 Gbits/s NRZ OOK signals. At a bit error rate (BER) of

, our proposed architecture revealed that 10 Gbits/s symmetric SS-WDM RoFSO can achieve 4.167 km of free space transmission. Power penalty of approximately 0.2 and 3 dB was achieved for downstream and upstream, respectively, which assures the feasibility of the proposed architecture. Such a system is meant to co-exist with the forthcoming fifth generation long-term evolution urban systems.
Adnominal conditionals in German
Authors: Blümel Andreas
Published: July 2019

In this short paper I give a description of salient structural and semantic properties of adnominal conditional clauses in German, drawn from online corpora (cf. Lasersohn 1996 for the English counterpart). Facts from prosody tentatively indicate, and from Binding, DP-internal distribution and extraposition more distinctively suggest, the paper’s main conclusion: Syntactically, adnominal conditionals behave like restrictive relative clauses. I sketch a recent analysis by Frana (2017), which captures important semantic properties of the construction. A restrictor analysis of conditional clauses can be retained and indeed fits snugly with the fact that only intensional nouns co-occur with, e.g. can be modified by, adnominal conditionals.
Ways of expressing counterfactual conditionals in Mandarin Chinese
Authors: Jiang Yan
Published: July 2019

This paper discusses the ways in which Mandarin Chinese expresses counterfactual conditionals, and endeavours to motivate and theorize the use of such strategies. I aim to give an overall picture of Mandarin Chinese counterfactual conditionals, a topic which has hitherto not been covered in the Chinese linguistic literature. The strategies identified are the use of special lexicalized chunks to directly encode counterfactual meaning; the creation of tense mismatch and the accompanying counterfactual meaning, either through the use of relative tense pointing toward a hypothetical past event, or through the use of some special time adverbs; and the use of pure inference over conditionals with impossible or absurd antecedents. Overlaying these strategies is the presence of context-dependent simplifications, which may prompt the language user to omit the defining features of a given strategy.
Variational-like inequalities for n-dimensional fuzzy-vector-valued functions and fuzzy optimization
Authors: Xie Ting , Gong Zengtai
Published: July 2019

The existing results on the variational inequality problems for fuzzy mappings and their applications were based on Zadeh’s decomposition theorem and were formally characterized by the precise sets which are the fuzzy mappings’ cut sets directly. That is, the existence of the fuzzy variational inequality problems in essence has not been solved. In this paper, the fuzzy variational-like inequality problems is incorporated into the framework of n-dimensional fuzzy number space by means of the new ordering of two n-dimensional fuzzy-number-valued functions we proposed [Fuzzy Sets and Systems 295 (2016) 19-36]. As a theoretical basis, the existence and the basic properties of the fuzzy variational inequality problems are discussed. Furthermore, the relationship between the variational-like inequality problems and the fuzzy optimization problems is discussed. Finally, we investigate the optimality conditions for the fuzzy multiobjective optimization problems.
Razumikhin-type theorem on time-changed stochastic functional differential equations with Markovian switching
Authors: Zhang Xiaozhi , Yuan Chenggui
Published: July 2019

This work is mainly concerned with the exponential stability of time-changed stochastic functional differential equations with Markovian switching. By expanding the time-changed Itô formula and the Razumikhin theorem, we obtain the exponential stability results for the time-changed stochastic functional differential equations with Markovian switching. What’s more, we get many useful stability results by applying our new results to several important types of functional differential equations. Finally, an example is given to demonstrate the effectiveness of the main results.

Published: July 2019

An efficient electrospun aligned surface enhanced Raman scattering (SERS) and maize-like substrate of polyvinyl alcohol (PVA) composite and Ag colloid nanofibers decorated with thermal evaporated Ag nanoparticles (AgNPs) has been developed by taking advantage of electrostatic interactions. The synergistic effects of the evaporated AgNPs (niblets) and the Ag colloid in PVA (corncob) could arouse strong electromagnetic field between the lateral and vertical nanogaps which has been demonstrated by experiment and finite-different time-domain (FDTD) simulation. In this experiment, the aligned nanofibers possesses an excellent sensitivity by detection of crystal violet (CV) and malachite green (MG) molecule at low concentration. Moreover, the proposed flexible SERS sensor was measured with outstanding uniformity and reproducibility. We also carried out in-situ electrospinning on a curved surface to detect the mixture of Sudan I, CV and MG molecule, which demonstrates that flexible SERS sensor, has enormous potential in accurate and in-situ detection on the complex geometric structure.
One-pot oligosaccharide synthesis: latent-active method of glycosylations and radical halogenation activation of allyl glycosides
Authors: Pal Rita , Das Anupama , Jayaraman Narayanaswamy
Published: July 2019

Chemical glycosylations occupy a central importance to synthesize tailor-made oligo- and polysaccharides of functional importance. Generation of the oxocarbenium ion or the glycosyl cation is the method of choice in order to form the glycosidic bond interconnecting a glycosyl moiety with a glycosyl/aglycosyl moiety. A number of elegant methods have been devised that allow the glycosyl cation formation in a fairly stream-lined manner to a large extent. The latent-active method provides a powerful approach in the protecting group controlled glycosylations. In this context, allyl glycosides have been developed to meet the requirement of latent-active reactivities under appropriate glycosylation conditions. Radical halogenation provides a newer route of activation of allyl glycosides to an activated allylic glycoside. Such an allylic halide activation subjects the glycoside reactive under acid catalysis, leading to the conversion to a glycosyl cation and subsequent glycosylation with a number of acceptors. The complete anomeric selectivity favoring the 1,2-trans-anomeric glycosides points to the possibility of a preferred conformation of the glycosyl cation. This article discusses about advancements in the selectivity of glycosylations, followed by delineating the allylic halogenation of allyl glycoside as a glycosylation method and demonstrates synthesis of a repertoire of di- and trisaccharides, including xylosides, with varied protecting groups.

The Double-Deviant Identity of the Mass-Foreigner and the Lack of Authority of the Crimmigrationist State
Authors: Spena Alessandro
Published: July 2019

Crimmigration has its breeding ground in dystopian and securitarian narratives. The anti-hero of these narratives is the mass-foreigner, a stereotyped version of the foreigner usually depicted, alternatively or cumulatively, as an enemy or as a parasite of host societies. But not only does crimmigration presuppose such narratives (and the deviant identity of the mass-foreigner, which is connected with them) as a source of legitimation, it also fuels these same narratives by providing them with an official sanction: by merging criminalization and irregularization on a legal level, it heavily contributes to making the social identity of mass-foreigners into a doubly deviant one. The overarching aim of this strategy is that of facilitating the exclusion of unwanted foreigners: first of all, their territorial exclusion (expulsion), but also, as a means to expulsion, their social exclusion (dereliction). This, I argue, deprives crimmigration of authoritative force—authority being inclusive in nature—and reduces it to mere violence.
The Hostile Border
Authors: Zedner Lucia
Published: July 2019

The concept of crimmigration recognizes the growing convergence of criminal law and immigration law as states seek to police migration, punish immigration offenses, and defend the boundaries of the sovereign state. Nowhere have these aims been pursued more vigorously than with respect to counter-terrorism, as states avail themselves of all legal means to target international terrorist networks and the rise of “foreign terrorist fighters.” In the U.K., legislative hyper-activity has produced a succession of counter-terrorist statutes that mix criminal law and immigration law. Some of the most draconian of these laws target the border and those who cross it. Closer attention to the territorial border reveals a liminal zone in which police and immigration officials enjoy exceptional powers and adherence to due process is attenuated. Apparent public acceptance of the imperatives of security at the border provides some license for such intrusions but little reassurance as to their legitimacy. This article examines the security concerns that motivate the expansion of police power, and it considers the impact of recent U.K. legislation, not least the Counter-Terrorism and Border Security Act 2019, on core principles of legality and on rights.

Published: July 2019

The Mossbauer studies of yttrium iron garnet (YIG) films grown on the gadolinium gallium garnet (GGG) substrate was realized for different films thickness (2.85 and 5.42 mm) at the applied external magnetic field. It is shown that the main changes in the magnetic microstructure of YIG/GGG films are occurred at magnetic field value up to 2.20 kOe. The changes of the hyperfine magnetic fields on the iron nuclei have been investigated and its isotropic component was analyzed. It was determined that the domain structure changes (in particular, the domains width enlarging) under the applied magnetic field increase with the film thickness decreasing.
The Library of Ignace Oginski (1755–1786): A Reflection of Geneological and Religious Identity
Authors: Pacevičius Arvydas
Published: July 2019

This article examines the development and the contents of the library of Ignacy Oginski, appointed elder of the Darsūniškis and Vaiguva communities; his collection of books is discussed with an emphasis on how the sense of self as well as geneological and religious identity are expressed. The library of I.Oginski is discussed within the context of the history of his family and closest relatives as well as his connections with the Bernardines of Trakai. The bibliographical and provenance analysis is founded on I. Oginski’s books, which are stored in Vilnius University Library (10 specimens); also published at the end of this paper is a list of books bestowed by I. Oginski to the Trakai Bernardine Monastery, which itself was added into the 1787 catalogue of the monastery’s library. It was determined that I. Oginski belonged to the third order of the Franciscan tertiaries and was a financial affairs trustee (i.e., a syndic, Lat. Sindicus Apostolicus) of the Trakai Bernardine Monastery, which he, together with his mother Antonina Oginska, had amply sponsored and to which he bequeathed upon death a sum of 7 thousand Lithuanian Zloty. I. Oginski bestowed his personal library, which consisted of 201 volume, to the Bernardines on March 29, 1786 based on a testament written in Kruonis. It contained not only the more traditional printed materials but also some sheet music characteristic of courtly culture, ledgers, and silva rerum manuscripts. Noteworthy is the prayer “On the Appeal for a Fulfilling Life” (Pol. O uproszenie stanu życia przyzwoitego), handwritten by I. Oginski himself. A large part of the library consisted of ascetic lectures, spiritual exercises, and sermons typical of the Bernardine monks, but the collection was not limited in this aspect, as it also had some secular French works from the Enlightenment period and textbooks printed by the publishing house of the Vilnius Piarists. The considerable number of historical works and books containing dedications with references to the merits of the Oginskis to the state and the Church shows that I. Oginski was particularly attentive of his family history. Generally, the library demonstrates quite clearly a promotional-religious aspect of I. Oginski’s genealogical sense of self and identity. And here, too, the ascetic literature supplements the data from other sources regarding I. Oginski’s piety and his belonging to the tertiary community. The carried out study of I. Oginski’s identity and his personal library’s development and the relevant associations confirms the available possibilities of using the approaches and methodologies of cultural anthropology and social communication in book science studies.

Los parásitos coccidiales afectan varias especies de reptiles a nivel mundial y son responsables de la muerte de cientos de ejemplares cautivos y silvestres en diferentes regiones del planeta. Entre los años 2011 y 2013, cuatro de 108 tortugas verdes (3,70 %) rescatadas por Grupo de Trabajo en Tortugas Marinas del Golfo de Venezuela, a través de la “Red de Aviso Oportuno (RAO)”, presentaron diferentes estadios evolutivos morfológicamente semejantes a Caryospora sp. en heces o tejidos. Los animales infectados fueron juveniles de tortuga verde capturados por pesquerías artesanales. Se les practicaron exámenes físicos, coprológicos y hematológicos. En tres ejemplares se observaron abundantes ooquistes de morfología compatible con Caryospora cheloniae (K001, K002, SB001). Uno de los animales presentó en capa blanca, leucocitos que contenían estructuras parecidas a esporozoitos de Caryospora sp, indicativo de coccidiosis sistémica. Dos de las tortugas se encontraron asintomáticas (K003, SB001), y dos se presentaron clínicamente enfermas con signos neurológicos como movimientos involuntarios de cabeza y aletas, espasmos musculares, movimientos natatorios circulares y depresión. Dos animales murieron (K001, K002), en ambos se encontraron diversos estadios de un organismo coccidial consistente con Caryospora sp. en intestino, además una enteritis necrótica moderada. Este constituye el primer reporte de coccidiosis en tortugas marinas en Venezuela y en el Caribe sur.

Los bosques tropicales del Chocó biogeográfico presentan una de las mayores concentraciones de especies de plantas del mundo. Las palmas (Arecaceae) son una de las familias más importantes en las tierras bajas del Chocó, pero su ecología está poco estudiada. Investigamos la diversidad de comunidades de palmas en el Chocó y su relación con la precipitación en 48 transectos distribuidos en un gradiente de 2000–10 000 mm de precipitación. En cada transecto (5×500 m) se identificaron todas las especies de palmas y se contabilizaron todos los individuos. Registramos un total de 57 especies de palmas (promedio ± DS: 17 ± 8 por transecto) y 37 955 individuos (791 ± 446). Encontramos que la riqueza y abundancia de palmas están significativamente relacionadas con la precipitación (r² = 0,86; P > 0,001). Se registró una fuerte correlación positiva entre la composición florística de las comunidades de palmas y la distancia geográfica (rm = 0,63; P = 0,001). La riqueza registrada es una de las más altas para el Neotrópico. La relación entre la precipitación, riqueza y abundancia de palmas por primera vez se documenta a escala regional en este punto caliente de biodiversidad.

Published: July 2019

Los páramos presentan altos niveles de diversidad y endemismo de especies y son importantes en la regulación hidrológica. Sin embargo, es uno de los ecosistemas más amenazados debido a actividades agrícolas y ganaderas. Los briófitos son un importante componente en términos de diversidad, bio-masa y funcionamiento de estos ecosistemas. Estos organismos poiquilohídricos son muy sensibles a cambios en el microclima relacionados con la humedad, luz y temperatura. Se evaluaron los efectos de las variables climáticas y topográficas sobre la diversidad de briófitos terrícolas en tres cimas del páramo del Parque Nacional Podocarpus, Ecuador. En cada cima se establecieron ocho parcelas de 1 × 1 m, donde se registró la incidencia y cobertura de briófitos terrestres. Se establecieron diferencias en la composición de especies de las tres cimas mediante un análisis de escalamiento multidimensional no métrico (EMNM) y los efectos de las variables climáticas y topográficas mediante un análisis multivariante basado en permutaciones (PERMANOVA). Nosotros encontramos que las diferencias en las comunidades de briófitos terrícolas estuvieron correlacionadas con la precipitación y pendiente. Se evidenció que las cimas con mayores niveles de precipitación y menos pendiente fueron importantes para la distribución y establecimiento de las comunidades de briófitos relacionados con una mayor retención de humedad del suelo.

Published: July 2019

El mono araña negro Ateles fusciceps está categorizado por la UICN como una especie críticamente amenazada (CR) y se estima que más del 80 % de la población se ha reducido en los últimos 45 años producto de la deforestación y la presión de cacería. La escasez de información sobre su presencia y el estado actual de sus poblaciones dificulta los esfuerzos de conservación a nivel local sobre la especie. Reportamos un avistamiento de A. fusciceps en un sitio sobre hábitat no idóneo (1778 m) dentro del Parque Nacional Natural Las Orquídeas al occidente de Colombia, lo cual permite reconocer la necesidad de enfocar estrategias de conservación para esta especie dentro del área y direccionar esfuerzos para el monitoreo de sus poblaciones, la restauración del hábitat y la disminución de la presión de cacería en las zonas consideradas óptimas (<850 m) para la permanencia de la especie.

Se reporta un caso de mortandad en juveniles de Nycticorax nycticorax en una colonia de reciente formación situada en una Reserva dentro de una matriz urbana lindante con el sistema de islas del río Paraná (Santa Fe, Argentina). Se monitorearon 138 nidos desde agosto a noviembre 2016. En agosto se registraron escasas muertes de pichones y juveniles. En septiembre, se registraron más de 800 pichones y juveniles muertos en el suelo, además de huevos abandonados por sus progenitores. No se evidenció mortandad inusual en otras especies de garzas que nidificaban en el área. Se tomaron muestras de seis individuos para realizar análisis de laboratorio y necropsias. Los individuos presentaron muy baja condición corporal y estómagos con escaso contenido, vesículas biliares distendidas e intestinos sin material sólido, con predominancia de contenido biliar (signo de ayuno), albúmina y otras proteínas séricas muy bajas, indicando muerte por inanición. Probablemente, esta mortandad se debió al abandono parental en edades donde las crías aún dependen de ellos para su alimentación. Se consideraron la interacción de múltiples causas, como la intervención humana, condiciones del hábitat, factores climáticos y densidad poblacional. No se conocen precedentes de tal magnitud de mortandad de aves acuáticas en el valle de inundación del Paraná Medio.
Composición florística y formas de vida de las macrófitas acuáticas de la serranía de La Lindosa (Guaviare), Guayana colombiana

Published: July 2019

La serranía de La Lindosa hace parte de los afloramientos rocosos del escudo Guayanés colombiano. Aunque la vegetación de este ecosistema ha sido estudiada, en esta región y en Colombia la diversidad de plantas acuáticas ha sido pobremente investigada. En este trabajo se caracterizó la flora acuática de La Lindosa mediante recolecciones generales en cuerpos de agua lóticos y lénticos. Se encontraron 110 especies en 70 géneros y 46 familias. Las familias más importantes fueron Cyperaceae (seis géneros/17 especies), Poaceae (diez/catorce) y Lentibulariaceae (una/catorce). Se reporta a Eleocharis alveolatoides como nuevo registro para la flora de Colombia y 38 para el Guaviare. La mayoría de las especies se localizaban en la ribera de los caños y la forma de vida arraigada emergente fue predominante. La cantidad de nuevos registros exponen la escasez de muestreos de macrófitas en la región, se muestra la gran riqueza de plantas acuáticas albergada en este macizo rocoso, y se destaca la presencia de elementos de distribución restringida. Lo anterior puede tener importantes implicaciones para la generación de mejores estrategias de conservación de esta zona.

Published: July 2019

Se describe la diatomea Hantzschia gadorensis como especie nueva a partir de muestras recogidas en una balsa ganadera en la Sierra de Gádor en Almería, España. Sus principales características son un bajo grado de dorsiventralidad, la ausencia de nódulo central y la presencia de conopeo que se registra por primera vez en el género, lo que permite distinguirla de especies similares. Los humedales de este sistema montañoso se confirman así como interesantes focos de biodiversidad aún por explorar.

Biological invasions are one of the main threats to forest health. Although Arhopalus rusticus and Arhopalus syriacus (Cerambycidae) are alien species in South America, the ecology of these invasive species is not well studied. Here, we examined the effect of the female size on potential fecundity, size and number of mature eggs in ovaries, in both insect species. We also compared egg morphometric characteristics, larval measurements, larval development and survival between these two species. We found a positive relationship between the female size and the number of eggs in their ovaries but no relationship between the female size and egg morphometric characteristics in each of these two species. The females of A. rusticus were significantly larger and had bigger eggs than those of A. syriacus, but no significant difference was observed in the number of eggs between them. Larval body length and head capsule exuviae width were larger in A. rusticus than in A. syriacus. Arhopalus rusticus had the highest larval survival rate, but A. syriacus had the shortest larval period. Thus, female and egg size, as well as larval size and survivorship are competitive advantages to A. rusticus. However, A. syriacus has a similar number of eggs to A. rusticus and faster larval development; these could be key features to explain the coexistence of these two species.
Biología reproductiva de Boana pulchella y Boana punctata (Anura: Hylidae) en poblaciones simpátricas de humedales templados

Boana pulchella habita principalmente climas templados y B. punctata principalmente climas tropicales, lo que permitiría suponer la presencia de estrategias reproductivas diferentes, aún en la región en la que sus poblaciones son simpátricas. En el presente estudio se analizaron y compararon los ciclos reproductivos, parámetros reproductivos y desarrollo de cuerpos grasos (CG) de Boana pulchella y B. punctata en humedales templados del río Paraná Medio. Boana pulchella presentó óvulos maduros de marzo a diciembre. En machos no hubo variación del volumen testicular a lo largo del año y el mayor desarrollo de CG de los machos se observó en invierno. Esta especie presentó un patrón reproductivo continuo. La vitelogénesis de B. punctata se inició en enero, alcanzando el mayor desarrollo ovárico en febrero (verano) y decreciendo hacia mayo (otoño). Los machos presentaron crecimiento testicular en verano, decreciendo hacia otoño y los CG presentaron su máximo desarrollo en enero para ambos sexos. Esta especie mostró un patrón reproductivo continuo. Ambas especies presentaron dimorfismo sexual con hembras que poseen una relación proporcional entre la talla y la inversión reproductiva. Boana pulchella presentó un mayor esfuerzo reproductivo (ER = 20,48 ± 12,9) y factor de tamaño ovárico (FTO = 25,73) que B. punctata (ER = 10,06 ± 4,45; FTO = 8,99). También se encontraron diferencias interespecíficas en la masa ovárica, complemento ovárico y volúmen testicular, siendo estas variables proporcionalmente mayores en B. pulchella. Las diferencias observadas en las poblaciones simpátricas podrían relacionarse con el desarrollo de estrategias reproductivas bajo diferentes presiones evolutivas.Material suplementario: https://doi.org/10.15446/caldasia.v41n2.80604

O que 3.3 nos diz sobre 3.333?
Authors: Silva Rafael
Published: July 2019

Este artigo apresenta uma hipótese exegética sobre a relação entre as proposições 3.3 e 3.333 do Tractatus Logico-Philosophicus. A pedra de toque dessa hipótese consiste em, na interpretação dessas proposições, seguir à risca o que Wittgenstein disse sobre a numeração das proposições do Tractatus – o que tem como efeito que 3.333 seria uma observação relativa à proposição 3.33, e esta, por sua vez, uma observação à proposição 3.3. A interpretação aqui defendida tem o propósito de mostrar como o princípio do contexto, formulado na proposição 3.3 do Tractatus, auxilia na solução do paradoxo de Russell, que tem sua solução enunciada em 3.333.
Interpretações boecianas sobre inferências tópicas e algumas considerações mereológicas
Authors: Da Cruz Luana Talita
Published: July 2019

Pode-se ver na abordagem da mereologia medieval uma conexão bastante forte entre a metafísica e a lógica. Questões ontológicas acerca de termos comumente utilizados em tratados lógicos e consideradas como questões lógicas não eram incomuns. Assim, as discussões mereológicas, surgem com frequência, em textos medievais, em meio a questionamentos lógicos e em textos mais claramente ligados a essa vertente. É o caso da mereologia ligada aos tópicos, em particular na interpretação boeciana desses. Da mesma forma que com o problema dos universais, o esforço dedicado a solucionar problemas mereológicos está entrelaçado às bases das inferências tópicas bem como com seu uso. Pretendemos, através desse texto, realçar a conexão do trabalho de Boécio enquanto lógico com as questões metafísicas que surgem do estudo do todo e suas partes. Acreditamos que a interpretação boeciana deve ser considerada neste aspecto, em primazia de outras, por sua influência lógica até o final do período medieval.
O problema da teoria das espécies e a origem do conhecimento humano em Tomás de Aquino
Authors: Borges Lucas Nogueira
Published: July 2019

As discussões sobre a teoria das espécies em Aquino estão situadas em três interpretações que discorrem acerca das relações dos atos do intelecto humano com o objeto externo. A primeira interpretação refere-se à espécie como um modo de acesso direto ao objeto, em que o intelecto seria capaz de acessá-lo por sua própria natureza. A teoria das espécies de Tomás, nessa interpretação, é classificada como um realismo direto ingênuo. A segunda interpretação estabelece, ao contrário, um representacionalismo. As espécies não seriam o primeiro objeto da apreensão. No processo do conhecimento, o objeto exterior seria conhecido secundariamente. Uma terceira interpretação sobre as espécies é a de um realismo direto modificado. Essa interpretação sustenta que as espécies são recursos cognitivos necessários, não implicando diferenças com o objeto externo. O intelecto visa o objeto externo. Por isso, o objeto externo é apreendido primariamente, enquanto a espécie, secundariamente, por um ato reflexivo. A proposta deste trabalho consiste em rever o debate entre Tomás e o platonismo acerca da origem do conhecimento humano, partindo dessas três interpretações descritas acerca das espécies inteligíveis. Num segundo momento, mostrar como as espécies inteligíveis podem ser tanto o id quod quanto o id quo, pois, no primeiro caso, a forma do objeto externo enquanto presente no intelecto é idêntica à forma do objeto externo no modo natural. No segundo caso, como a intelecção de algo material no modo imaterial necessita de um intermediário, mas não de um intermediário que seja o primeiro objeto de conhecimento intelectivo.
Ensaio sobre o caráter metafísico das medições
Authors: Pinheiro Félix Flores
Published: July 2019

O texto que segue consiste um ensaio sobre o caráter metafísico das medições, discorrendo sobre como a reflexão filosófica sobre essa atividade científica envolve elementos de discussões metafísicas. A filosofia da ciência contemporânea possui uma subárea de investigação denominada de “filosofia da medição”. Tendo em vista os problemas filosóficos que emergem da prática científica, a filosofia da medição constitui um campo de estudo que investiga certos questionamentos epistêmicos, ontológicos e metafísicos sobre a natureza das medições, os quais podem ser exemplificados em três tópicos gerais: 1) em vista do que podemos medir algumas coisas e não outras; 2) quais condições tornam as medições possíveis; e 3) o que significam os resultados das medições. O presente texto possui por objetivo evidenciar em que sentido as investigações em filosofia da medição tocam questionamentos metafísicos. O principal argumento do presente artigo pode ser assim entendido: apesar das teorias filosóficas sobre as medições possuírem um viés epistêmico, compreender o significado das relações envolvidas nos processos de mensuração remete ao milenar problema filosófico sobre como o abstrato se relaciona com o concreto, portanto, há questões metafísicas permeando qualquer análise filosófica sobre as medições.
Outras epistemologias – múltiplas narrativas sobre sexo, gênero e papéis sociais
Authors: Marim Caroline Izidoro
Published: July 2019

Em seu artigo “Visualizing the Body: Western Theories and African Subjects” Oyèrónké Oyěwùmí aponta que os Estudos Africanos continuam sendo ocidentocêntricos, isto é, ainda utilizam teorias e conceitos operativos derivados de experiências ocidentais. O primeiro problema que ela aponta é com a universalização dos papéis sociais e das identidades enraizados na biologia. Segundo, a cultura ocidental privilegia o sentido visual em detrimento dos outros sentidos reduzindo o corpo a um marcador de diferenças que implicam exclusões de outras narrativas sobre sexo, gênero e papéis sociais. Considerando a epistemologia social feminista de Donna Haraway, de que diferenças experienciais levam a diferenças de perspectiva e essas diferenças carregam consequências epistêmicas, o objetivo deste artigo é mostrar de que modo sua teoria sobre narrativas situadas é capaz de contribuir para que as dificuldades apresentadas por Oyěwùmí sejam recolocadas em um cenário epistemológico mais amplo. Quais as limitações que a epistemologia ocidentocêntrica tem submetido não apenas outras epistemologias, mas também tem limitado a própria ampliação de narrativas no ocidente?

THE DEVELOPMENT ADVANCED GRANULATION TECHNOLOGY OF COMPOUND FEEDS
Authors: Yegorov B. , Batievskaya N.
Published: July 2019

The advantages of using granular mixed fodders in comparison whith the loose сompound feeds have been analyzed in the article. A detailed analysis of the production of granulated feed in the world and in Ukraine for the last ten years has been presented. The article is dedicated to the justification of the use of granulation technology in the feed industry. The advantages and disadvantages of granulation technology are presented, as well as the structural scheme of the traditional technology of production of granulated mixed fodders with the receipt of granules grains is considered. The detailed analysis of technological processes of the traditional technology ofgranulated mixed fodders production with the receipt of granule grains with the description of technological regimes of each process has been given. The main disadvantages of traditional technology of granulated feed production have been considered and possible solutions of these problems are presented. As the development of the feed industry is characterized by the intensification of technological processes aimed primarily at improving sanitary quality, the methods of preliminary wet-heat preparation of mixed fodder, in particular, the application of expansion to the granulation process, have been presented as the basis for further development of the advanced granulation technology. The advantages of using expansion, the principle of the expander and the technological features of the process have been considered. The generalization of the conducted analytical and experimental studies allowed to develop the advanced technology of granulation in the form of a blend granulated crumb, which will increase the output of finished products. The technology for the production of granulated сompound feed in the form of a blend granulated crumb and expanded crumb have been presented in the article. The description of technological processes and technological regimes (moisture of products, use of sieves, vapor pressure, steam consumption, duration, etc.) have been presented too. The physical and microbiological characteristics of granulated and expanded feed, as well as granulated grains and expanded grains are given.
