Partasasmita R, Iskandar J. Malone N. 2015. Karangwangi peopleâ€™s (South Cianjur, West Java, Indonesia) local knowledgeÂ of species, forest utilization and wildlife conservation. Biodiversitas 17: 154-161. In the past, many West Javan Villages had a high diversity of wildlife. Nowadays, however, the diversity of wildlife in these villages has tended to decrease rapidly. This is caused by many factors, including the loss or destruction of wildlife habitat destruction, intensive use of pesticides in the agricultural sector, and illegal hunting. Animal hunting is typically undertaken by villagers for various purposes, such as to fulfill household meet consumption, as well as for the capture and trading of pets. Traditionally, the use of wildlife by the Sundanese people of West Java is influenced by corpus (local knowledge) and cosmos (beliefs). As a result, the wild animals have been utilized within a sustainable system that enablesÂ wildlife conservation. Today, however, a lot of traditional knowledge or local knowledge of wildlife has eroded. This paper elucidatesÂ local knowledge of Karangwangi villagers of Subdstrict of Cidaun, District of Cianjur, Province of West Java, Indonesia on variousÂ species, utilization, and the conservation of wildlife. Methods used in this study are a combination of qualitative and quantitativeÂ techniques based on an ethnozoological approach. The result of study shows that the respondents recognize at least 45 species ofÂ wildlife consisting of 15 mammalian species, 21 species of Aves, and 9 species of herpetofauna. Based on the perception of respondents,Â those wildlife species have various socio-economic and cultural saliences (eg. household meat consumption, pets, trading, and appearingÂ in mythology),Â as well as various ecological functions (e.g., crop pests, pest controls, and seed dispersal). Some cultural myths related with wildlife have been recorded and partly determine the utilization of wildlife by village people.
Os costumes no planalto catarinense: dos embates no movimento sertanejo do Contestado à luta contra as imposições do capital estrangeiro (1912-1919).
Authors: Tomporoski Alexandre Assis 
Published: March 2016

Este artigo tem por objetivo analisar os costumes praticados pelos sertanejos do planalto catarinense, adotados desde o século XVIII, a partir dos quais emergiram relações de solidariedade e relações conflituosas, aplicadas pelos sertanejos nos embates da Guerra do Contestado e na luta contra as imposições do capital estrangeiro em expansão na região. Com este intuito, o texto ampara-se no enfoque de capital social para expor as relações solidárias e conflituosas, oriundas das práticas dos costumes pelos sertanejos. O exame minucioso dos costumes utilizados nas práticas laborais, isto é, o pixirum, a roça cabocla e a criação comunal de animais, assim como dos costumes utilizados nas práticas religiosas, representados principalmente pela devoção a São João Maria, o fandango de São Gonçalo e as festas religiosas, oferece nova perspectiva sobre as relações solidárias e conflituosas entre os sertanejos. Esse entendimento desvela que, em suas relações conflituosas nos desdobramentos do movimento sertanejo do Contestado e em oposição ao avanço do capital estrangeiro, os sertanejos não foram meros jagunços ou fanáticos, mas pessoas dotadas de uma profunda racionalidade – proveniente de seus costumes – que lutaram por aquilo que consideravam justo e seu por direito.

Authors: Beltrán Vargas Julio Eduardo 
Published: March 2016

<p>Se presenta un modelo de simulación dinámico para explicar el comportamiento general de la producción primaria fitoplántonica en el humedal de Jaboque – Bogotá D.C., Colombia, en tres secciones con características físicas y químicas diferenciales. El modelo tiene en cuenta las variables fisicoquímicas, área de la cubeta, profundidad, precipitación media anual, temperatura del agua, pH y concentración de clorofila_a. La modelación dinámica se basó en ecuaciones diferenciales y se utilizó el método Euler de integración, la modelación se desarrolló utilizando el programa computacional Stella 9.1<sup>®</sup>. El modelo permite cuantificar la producción primaria fitoplántonica del humedal de Jaboque a partir de la concentración promedio mensual de clorofila_a, para cada sección. Los resultados de la modelación de la Ppf evidencian que las variaciones de la concentración de la Ppf en cada sección del humedal siguen un patrón inverso al comportamiento bimodal de la precipitación. Se encontró un alto grado de correspondencia entre los valores de clorofila_a de campo y la Ppf modelada de la siguiente manera <em>r<sup>2 </sup>= 0.86</em> para la primera sección y <em>r<sup>2</sup> = 0.86</em> y <em>r<sup>2</sup> = 0.79</em> para las secciones restantes. La determinación del error relativo fue de 0,57, para la primera sección y 0,35; 0,46, indicando que los resultados no están sobrestimados. El modelo muestra en términos generales los aspectos funcionales del comportamiento de la Ppf y su relación con el proceso de eutroficación, y permite hacer recomendaciones para el manejo y restauración del humedal.</p>
Sinn braucht ein Fundament – Überlegungen zur Struktur der Anerkennung / Sense needs a fundament – considerations on the structure of appreciation
Authors: Fischer Ute 
Published: March 2016

Zusammenfassung
Sinn ist auf mehreren Ebenen konstituiert: im subjektiven Sinnerleben innerhalb des Arbeitsvollzugs, in gesellschaftlich verankerten objektiven Handlungsstrukturen sowie als normativer Ausdruck anerkannter Formen der Existenzsicherung, wie sie in der Sozialpolitik Niederschlag finden. Zwischen Sinn und Anerkennung herrscht nicht immer Übereinstimmung. Der Beitrag beleuchtet daher insbesondere die Beziehungen zwischen den drei Ebenen und stellt Inkohärenzen heraus an Stellen, wo Sinnvolles keine Anerkennung findet. Ausgehend davon wird der Vorschlag des Bedingungslosen Grundeinkommens auf sein kohärentes Potenzial hin untersucht.

AbstractTooth bleaching agents may weaken the tooth structure, therefore, it is important to minimize any risks of enamel and dentine damage caused by them. In this way, different materials have been used to avoid or minimize the tooth damage during bleaching. Recently, bioactive glasses have been demonstrated to be effective in mineralization of dental structures. Therefore, this study evaluated the effect of BioSilicate® (a polycrystalline bioactive glass-ceramic) after bleaching by Laser-induced breakdown spectroscopy (LIBS) technique. Bovine dental blocks with 4 × 4 × 3 mm were obtained (n = 20), sequentially embedded in epoxy resin and then polished. Bleaching was performed using 35% hydrogen peroxide (Whiteness HP). Calcium (Ca) and phosphate (P) intensity values by LIBSwere obtained before the treatment (T0, baseline – control Group), after bleaching (T1), and after BioSilicate® application (T2). The use of BioSilicate® after bleaching showed to be an optimal way to remineralize enamel surface making BioSilicate® application a promising adjunct step to avoid or minimize the mineral loss on enamel surface after bleaching.

A criterion for a finite permutation group to be transitive
Authors: Brough Julian 
Published: March 2016

Abstract
Let G be a finite permutation group on a finite set Ω.
We say that G is quasi-transitive if every 2-point stabiliser has the same order.
This notion was introduced by Alan Camina.
In particular, Camina established conditions for a quasi-transitive group to be transitive.
The aim of this note is to validate Camina's conjecture: A quasi-transitive group G on a finite set Ω is transitive on Ω.
Weak commutativity between two isomorphic polycyclic groups
Authors: Lima Bruno César R. , Oliveira Ricardo N. 
Published: March 2016

Abstract
An operator of weak commutativity between isomorphic groups, H and H
ψ, was defined by Sidki as
χ(H) = 〈H
H
ψ | [h,h
ψ] = 1 for all h ∈ H〉,
where ψ : h ↦ h
ψ for all h ∈ H defines an isomorphism.
It is known that the operator χ preserves group properties such as
finiteness, solubility, and also nilpotency for finitely generated groups. We
prove in this work that χ preserves the properties of being polycyclic
or polycyclic-by-finite. As a consequence of this result, we conclude that
the non-abelian tensor square H ⊗ H of a group H as defined by Brown
and Loday preserves the property of being polycyclic-by-finite. This last result
extends work of Blyth and Morse who proved that H ⊗ H is polycyclic
if H is polycyclic.

The Effect of Image Speed on Novice Golfers’ Performance in a Putting Task
Authors: H. Shirazipour Celina , J. Munroe-Chandler Krista , Loughead Todd M. , Vander Laan Anthony G. 
Published: March 2016

Abstract
The PETTLEP model provides guidelines for employing imagery, including suggestions for image speed. Current models and research emphasize real-time image speed, with the possibility for benefits from slow-motion images when learning a task. This study investigated the effect of three different image speeds (real-time, slow-motion, and fast-motion) on 56 novice golfers’ performance in a putting task. Results demonstrated significant differences in performance among fast-motion and all other image speeds, such that performance was worse following fast-motion imagery compared to performance following other image speeds. There was no difference between performance in slow-motion and real-time image speed conditions. These findings could potentially aid in improving the delivery of imagery interventions to novice athletes.
Contextualized Latent Semantic Indexing: A New Approach to Automated Chinese Essay Scoring
Authors: Xu Yanyan , Ke Dengfeng , Su Kaile 
Published: March 2016

AbstractThe writing part in Chinese language tests is badly in need of a mature automated essay scoring system. In this paper, we propose a new approach applied to automated Chinese essay scoring (ACES), called contextualized latent semantic indexing (CLSI), of which Genuine CLSI and Modified CLSI are two versions. The n-gram language model and the weighted finite-state transducer (WFST), two critical components, are used to extract context information in our ACES system. Not only does CLSI improve conventional latent semantic indexing (LSI), but bridges the gap between latent semantics and their context information, which is absent in LSI. Moreover, CLSI can score essays from the perspectives of language fluency and contents, and address the local overrating and underrating problems caused by LSI. Experimental results show that CLSI outperforms LSI, Regularized LSI, and latent Dirichlet allocation in many aspects, and thus, proves to be an effective approach.
On the gravity and geoid effects of glacial isostatic
adjustment in Fennoscandia - a short note
Authors: Sjöberg L. E. 
Published: March 2016

Abstract
Many geoscientists argue that there is a gravity
low of 10-30 mGal in Fennoscandia as a remaining fingerprint
of the last ice age and load, both vanished about
10 kyr ago. However, the extraction of the gravity signal
related with Glacial Isostatic Adjustment (GIA) is complicated
by the fact that the total gravity field is caused by
many significant density distributions in the Earth. Here
we recall a methodology originating with A. Bjerhammar
35 years ago, that emphasizes that the present land uplift
phenomenon mainly occurs in the region thatwas covered
by the ice cap, and it is highly correlated with the spectral
window of degrees 10-22 of the global gravity field, whose
lower limit fairly well corresponds to the wavelength that
agrees with the size of the region. This implies that, although
in principle the GIA is a global phenomenon, the
geoid and gravity lows as well as the land upheaval in
Fennoscandia are typically regional phenomena that cannot
be seen in a global correlation study as it is blurred by
many irrelevant gravity signals. It is suggested that a regional
multi-regression analysis with a band-limited spectral
gravity signal as the observable, a method tested already
2 decades ago, can absorb possible significant disturbing
signals, e.g. from topographic and crustal depth
variations, and thereby recover the GIA signal.

1,3-Oxazinan-2-ones via carbonate chemistry: a facile, high yielding synthetic approach
Authors: Aricò Fabio , Bravo Sara , Crisma Marco , Tundo Pietro 
Published: March 2016

Abstract
A high yielding synthesis of 1,3-oxazinan-2-ones starting from 3-amino-1-propanols and ethylene carbonate (EC) in the presence of catalytic amount of triazabicyclodecene (TBD) is herein reported. The formation of six-membered cyclic carbonates was achieved by intermolecular cyclization reaction via double BAc2 mechanism. Cyclization reactions have been carried out in neat as EC acted both as solvent and reagent. Pure 1,3-oxazinan-2-ones were isolated in high yield by simple liquid-liquid extraction. Further purification can be achieved by recrystallization. The reaction resulted of general application on different substrates including an aryl bis(3-amino-proan-1-ol) compound.
New opportunities in the stereoselective dearomatization of indoles
Authors: Manoni Elisabetta , De Nisi Assunta , Bandini Marco 
Published: March 2016

Abstract
The regio- and stereoselective dearomatization of indoles is realized for the first time by combining readily available indolyl precursors and electron-rich allenes, namely allenamides and aryloxyallenes. Inter- as well as intramolecular condensations were realized under gold and Brønsted acid catalysis providing a range of densely functionalized indoline and indolenine cores in high yields and excellent stereochemical outcome. Chemodivergent reaction profiles (Micheal-type addition vs. [2+2]-cycloaddition) were realized by a tailored design of both reaction conditions and functionalization of the reaction partners.
