Authors: Paskarina Caroline
Published: April 2017

Although Indonesia is an archipelagic state, but the discourse on maritime state is not yet become the main discourse in the construction of nation and state of Indonesia. This discourse is reemerged when President Joko Widodo make it as one of the main strategic agenda of hisadministration. The re-emerging of this maritime nation discourse is interesting to be studied in terms of nationalism, as an attempt to reconstructing the Indonesian national identity imagination. By tracking the dynamics of the arguments that enliven the discourse in Indonesian politics, this paper wants to uncover why this discourse re-emerged and what is the political interests behind thereimagination of Indonesian nationalism.
SOSIALISME ISLAM: PERSPEKTIF PEMIKIRAN POLITIK H.O.S. TJOKROAMINOTO
Authors: Manan Firman
Published: April 2017

In several literatures of Indonesian political thought, the ideas of socialism has been claimed as the doctrine came from and influenced by western political thought. On the other side, Islam political thought has been seemed as the doctrine came from Indonesia traditional heritages. These view was rejected by H.O.S. Tjokroaminoto who argues that socialism has been established and flourished inthe Islamic tradition before it was developed in the West. This article tries to describe H.O.S. Tjokroaminoto’s political thought about Islamic socialism which was constructed in the Islamic tradition rooted from Al-Quran and As-Sunnah.
The power of EFL student-researchers: A critical discourse analysis project “Hey, teachers, leave them kids alone”
Authors: Sadek Nihal , Sassi Rena
Published: April 2017

Learner autonomy has been called for by many researchers in language teaching. Learner independence can be achieved through empowering students (Ss) by training them on ways to learn certain learning strategies rather than just teaching them certain linguistic features. This goal can be attained through implementing the learner-as-researcher approach called for by many researchers due to its potential ability to involve Ss in their learning process. This paper presents the findings of a multifaceted action research project intended to enhance Ss’ critical skills through implementing the Riggenbach Model (1999) to a linguistic micro aspect; learn more about Teacher –Student (T-S) interactions through critically analyzing a number of T-S interactions using Dobbs’ analysis model presented in Celce-Murcia and Olstein (2000), and use critical classroom discourse analysis (CCDA) to provide a macro-analytic explanation of identity and power relations of the Ss by examining student reflections and final products.
A discourse analysis of Melengkan at a Gayonese wedding ceremony
Authors: Jaya Irama , Daud Bukhari
Published: April 2017

Melengkan is a special form of the Gayonese language which is spoken in poetry, lyrics, and proverbs. This study investigated its use as poetry specifically in wedding ceremonies held in Gayo, Aceh, Indonesia. The data was collected by observations and a video-recording of a traditional Gayonese wedding ceremony, as well as from interviews with melengkan speakers. We described and analyzed the context of the use of melengkan, the form of melengkan, and the cultural values conveyed through melengkan used in the wedding ceremony. The findings showed that there were six types of melengkan: Melengkan Turun Caram, Melengkan Beguru, Melengkan Munyerah Rempele, Melengkan Munerime Rempele, Melengkan Munyerah Munenes and Melengkan Munerime Munenes. The values of melengkan are for remembrance of local knowledge, warnings from customary philosophy, warnings from religion, and also for giving advice and recall the history and beauty of melengkan speech. The context of using melengkan is to perpetuate and reflect cultural values, namely, politeness, respect, speaking softly, friendliness and resoluteness. These findings imply the importance of conserving melengkan as part of the Gayonese culture in every part of their life.
A study of ontogenetic level of language development and gender differences affecting language use in Acehnese language
Authors: Aulia Muhammad
Published: April 2017

There have been numerous studies analysing gender differences in language use. Most of them predominantly adopted static or hierarchical approach with obsolete understanding of gender differences. Concurrently with the high demand of socio-cultural aspects inclusion in language development studies, the research of gender in language use has also driven to the same direction with mixed talk and the use of dynamic approach as an alternative for more inclusive socio-cultural spectrum. Two student university classes were observed and their classroom conversations in mixed gender were meticulously selected for detailed analysis via N-VIVO. The study shows that social dimensions such as power, status, economy, and identity seem to be influential to Acehnese language users in mixed talks. Yet, some mixed talks are more likely to be affected by individual ontogenetic language development; the dominance of talk is relatively fading and mutual-respect is bold. Therefore, the advocacy for the dynamic approach to conducting further research in this domain is decisively important. It is also crucial for more thorough and deep analysis on the genetic language development of speakers such as their social backgrounds and study or learning experiences. This paper draws merely a minor part of a larger research project conducted in Aceh and is expected to be a trigger for future studies.

The objective of this research was to study the role of organic and NPK compound fertilizers application to one-year-old oil palm (Elaeis guineensis Jacq.) on marginal land. The research was conducted at IPB-Cargilll Teaching Farm of Oil Palm, Jonggol, Bogor, West Java from March 2013 to March 2014. The experiment was carried out as factorial experiment in a randomized block design with three replications. The first factor was organic fertilizer consisted of 0, 15, and 30 kg per palm. The second factor was NPK compound fertilizers 15:15:15 consisted of 0, 1.3 and 2.6 kg per palm. The results showed that no interaction effect between organic and NPK compound fertilizers on all of variables observed. Marginal soils in Jonggol required high rate of fertilizers to produce good performance of one-year-old oil palm. Application of 30 kg organic fertilizer per palm or 2.6 kg NPK compound fertilizers 15:15:15 per palm resulted in the highest vegetative growth of one-year-old oil palm on marginal land in Jonggol.

ABSTRACT

Fertilizer application in elephant foot yams (Amorphophallus paeoniifolius (Dennst.) Nicolson) intercropping system is rare in Indonesia, therefore, NPK fertilizers experiment was conducted under the shade of 10-year-old coffee plantation at Leuwikopo Experimental Farm, Bogor, Indonesia, in order to increase the productivity of elephant foot yam intercropped with coffee trees. Prior to planting, 20 ton ha-1 of goat manure was applied. Four NPK combinations, i.e., N, P2O5, K2O at the rate of 0, 0 and 0; 100, 60 and 80; 125, 60 and 100; and 150, 60 and 120 kg ha-1, were applied. Results showed that there were no significant differences in leaf number per plant, petiole size and rachis length among treatments. Application of NPK decreased photosynthetic rates, while increasing rate of N and K2O had no effect on photosynthetic rates. NPK application at the 100 N, 60 P2O5 and 80 K2O kg ha-1 (N100P60K80 treatment) or larger prolonged growth duration regardless of NPK levels, and there was a close relationship between corm yield and growth duration. As a result, corm fresh mass was higher in the 100:60:80 kg ha-1 treatment than in control. In the N125P60K100 and N150P60K120 kg ha-1 treatments, leaves were damaged by heavy rains and winds, counteracting beneficial effect of NPK on growth duration and corm yield. These results suggested the importance of delay of entering dormancy for an increase in productivity of A. paeoniifolius.

ABSTRACT

Barnyard grass (Echinochloa crus-galli (L.) P. Beauv.) is a major weed competitor to rice production in Indonesia. In order to develop integrated weed management program, a research to select competitive rice lines to E. crus-galli was conducted in a green house of Indonesian Centre of Agricultural Biotechnology and Genetic Resource Research and Development Bogor. The research design was split plot with four replications, E. crus-galli was designed as the main plot (rice without E. crus-galli compared  rice with four E. crus-galli per pot), and the sub-plots were 25 genotypes (23 lines, 1 tolerant variety and 1 sensitive variety). Level of tolerance was determined by the reduction percentage of grains weight, the number of productive tillers and dry matter weight. The results showed that rice competition with E. crus-galli reduced plant height, productive tiller numbers, filled spikelet numbers per panicle, dry matter weight and dry grain weight. Three lines, i.e., IR10L-155, IR10L-133 and BIO-R84-1 were classified as tolerant, 19 lines were moderate and 3 lines were sensitive to E. crus-galli competition.

ABSTRACT

Increased of plant productivity in field determined by the use of quality seed from improved variety. The purpose of this research was to study the effect of frequency and volume of phyllosphere biological agents by foliar spray on rice plant infected by Xanthomonas oryzae pv. oryzae (Xoo) in improving plant growth, production of rice seed, and controlling bacterial leaf blight (BLB). This research was conducted at Seed Health Laboratory, Department of Agronomy and Horticulture, Bogor Agricultural University, and Muara Experimental Field, Rice Research Institute, March through September 2014. The experiment was conducted using a randomized complete block design with two factors, and replicates as blocks. The first factor was five levels of frequency of spraying with biological agents: P0 = control, P1 = Xoo seed inoculated then invigorated with biomatriconditioning, P2 = Xoo inoculated seed, then biomatriconditioned, and the plants were sprayed with phyllosphere biological agents F112 once, P3 = as P2, and the plants were sprayed with F112 twice, and P4 = as P2, and the plants were sprayed with F112 three times. The second factor was three levels of spray volume: i.e., 300, 400, and 500 L ha-1. Result of this experiment revealed that biomatriconditioning with rhizobacteria P. diminuta A6 and B. subtilis 5/B improved field emergence and seedling dry weight. Seeds applied with biomatriconditioning then followed by foliar spray with phyllosphere bacteria F112 at 40, 60, and 80 days after transplanting effectively reduced severity of BLB, increased plant dry weight and seed yield. All treatments increased yield as compared to untreated control. Volume of foliar application showed no significant difference, therefore, the lowest volume of 300 L ha-1 was recommended.

ABSTRACT

The morphophysiology of ratoon is different from the main plant of rice and was influenced by location and cultivation.This research was intended to evaluate morphophysiology characters of rice ratoon planted by direct seeding system in tidal swamp at various stubble cutting height. The experiment was conducted in November 2013-April 2014 at tidal swamp overflow type B in Telang Sari Village, District of Tanjung Lago, Banyuasin, South Sumatra Province. The experiment used randomized block design with 5 replications. Treatment was stubble cutting height 10, 20, 30, 40 and 50 cm above the soil surface. Rice was planted at 4 m x 5 m plot, the distance between plot 1 m. Data were analyzed by test of variance and 5% HSD test. Morphophysiological characters of rice ratoon were influenced by stubble cutting height. Cutting height of 20-40 cm above soil surface increased the ratoon number of tillers per hill, leaf area per hill, dry weight per hill, percentage of empty grains per panicle, grain weight per hill and percentage ratoon/main crop production per hill. The higher stubble cutting, the lower the number of leaves per tiller, leaf area per tiller, carbohydrate content, and number of grains per panicle of ratoon, however it accelerated age of flowering and harvesting.

Published: April 2017

Cocoa (Theobroma cacao L.) is a cash crop of huge economic significance in the world and the key raw material for chocolate manufacturing. Polyphenol oxidases (PPOs) are copper containing oxidoreductases that catalyze the hydroxylation and oxidation of phenolic compounds in the presence of molecular oxygen. The PPO presence and activity during fermentation and drying of cocoa beans is responsible for the development of flavor precursors. In this study, bioinformatics analysisof PPO from cocoa was done using standard bioinformatics tools such as Blastp, Hmmer, ClustalO, OMABrowser, EMBOSS and Swissmodel. The result showed that cocoa PPO homologs include Citrus sinensis, Populus euphratica, Gossypium raimondii, Litchi chinensis, Dimocarpuslongan, Canarium album, while the orthologsobtainedinclude Sorghum bicolor, Zea may, Manihot esculenta and Vitis vinifera among others.PPO of Solanum lycopersicum (tomato) was found to be a distant homolog of cocoa PPO, and that this evolutionary relationship implicated Witches’ Broom Disease (WBD). The computed physicochemical properties were in alignment with the experimental results. Keywords: Polyphenol Oxidase, Cocoa, Theobroma cacao L., Computational Analysis, Experimental Analysis.

The Effect of Welding Speed on the Weld Seam Profile in MAG and TIG/MAG Hybrid Arc Welding
Authors: Uzun A.
Published: April 2017

The effect of welding speed on the weld seam profile in MAG and TIG/MAG hybrid arc welding was investigated in a low carbon steel. AISI 1020 steel materials having 5 mm thickness were used in the experiments. A fixed MAG and TIG welding currents (90 A and 100 A, respectively) and three different welding speeds (0.14, 0.21 and 0.30 m/min) were selected for welding process for a 100 mm long weld. The welded specimens were cut into several cross-sections; then metallographic tests were performed. The effect of TIG/MAG hybrid arc welding process was compared with the conventional MAG welding. The study showed that welding speed and the selected method have influence on the penetration and that the ratio of penetration depth / weld seam width is increased with increasing welding speed. This increase is more pronounced in TIG/MAG hybrid arc welding compared to conventional MAG welding. The microstructure of the weld metal was also changed relatively by variation of welding speed. With all welding parameters, the weld metal hardness is higher than hardness of the HAZ and the base metal.

Abstract

This article explores the process of interpreting bodily sensations after completed cancer treatment. We base our analysis on repeated interviews over a period of 12 months with eight participants who had different cancer diagnoses. By using the concepts of ‘sensation schemas’ and ‘sensation scripts’, we explore how sensation schemas of cancer dominated in the first period, while schemas of late effects and reduced tolerance for daily life activities gradually became more important as time went by. Scripts, or actions taken to reduce unpleasant sensations, gradually turned from seeking medical advice and check-ups to ignoring and waiting for it to go away. Later, adapting daily life to the new health situation became prominent, such as balancing rest and activity to avoid becoming exhausted.

Abstract

Patient-related diagnostic delay has been established as an analytical category in cancer research. This category has come under critique because it postulates linear cause-and-effect explanations of delayed care-seeking. These explanations are based on a one-dimensional idea of causality that neglects the processual character and the contextual situatedness of bodily experiences and care-seeking decisions. Using a notion of causality that is both process-oriented and context-sensitive, this article aims to understand ovarian cancer patients’ stories on delayed healthcare seeking. It uses data from a qualitative interview study that investigated ovarian cancer patients’ illness and healthcare-seeking experiences. We suggest that the interviewees’ retrospective perspective generated a multilayered notion of diagnostic delay that differs from the definition of patient-related delay commonly used in the literature. Our analysis shows how interviewees negotiate current social discourses on health and (social) responsibility, and thereby situate themselves and their healthcare seeking within a broader socio-economic and political context.
Adaptive Changes in the Perception of Fast and Slow Movement at Different Head Positions

Published: April 2017

BACKGROUND: This paper examines the subjective sense of orientation during asymmetric body rotations in normal subjects.METHODS: Self-motion perception was investigated in 10 healthy individuals during asymmetric whole-body rotation with different head orientations.
Both on-vertical axis and off-vertical axis rotations were employed. Subjects tracked a remembered earth-fixed visual target while rotating in the dark for four cycles of asymmetric rotation (two half-sinusoidal cycles of the same amplitude, but of different duration).RESULTS: The
rotations induced a bias in the perception of velocity (more pronounced with fast than with slow motion). At the end of rotation, a marked target position error (TPE) was present. For the on-vertical axis rotations, the TPE was no different if the rotations were performed with a 30° nose-down,
a 60° nose-up, or a 90° side-down head tilt. With off-vertical axis rotations, the simultaneous activation of the semicircular canals and otolithic receptors produced a significant increase of TPE for all head positions.DISCUSSIONS: This difference between on-vertical and
off-vertical axis rotation was probably partly due to the vestibular transfer function and partly due to different adaptation to the speed of rotation. Such a phenomenon might be generated in different components of the vestibular system. The adaptive process enhancing the perception of dynamic
movement around the vertical axis is not related to the specific semicircular canals that are activated; the addition of an otolithic component results in a significant increase of the TPE.Panichi R, Occhigrossi C, Ferraresi A, Faralli M, Lucertini M, Pettorossi VE. Adaptive changes

Published: April 2017

BACKGROUND: Divers try to limit risks associated with their sport, for instance by breathing enriched air nitrox (EANx) instead of air. This double blinded, randomized trial was designed to see if the use of EANx could effectively improve cognitive performance while diving.METHODS:
Eight volunteers performed two no-decompression dry dives breathing air or EANx for 20 min at 0.4 MPa. Cognitive functions were assessed with a computerized test battery, including MathProc and Ptrail. Measurements were taken before the dive, upon arrival and after 15 min at depth, upon surfacing,
and at 30 min postdive. After each dive subjects were asked to identify the gas they had just breathed.RESULTS: Identification of the breathing gas was not possible on subjective assessment alone, while cognitive assessments showed significantly better performance while breathing
EANx. Before the dives, breathing air, mean time to complete the task was 1795 ms for MathProc and 1905 ms for Ptrail. When arriving at depth MathProc took 1616 ms on air and 1523 ms on EANx, and Ptrail took 1318 ms on air and and 1356 ms on EANx, followed 15 min later by significant performance
inhibition while breathing air during the ascent and the postdive phase, supporting the concept of late dive/postdive impairment.DISCUSSION: The results suggest that EANx could protect against decreased neuro-cognitive performance induced by inert gas narcosis. It was not possible
for blinded divers to identify which gas they were breathing and differences in postdive fatigue between air and EANx diving deserve further investigation.Germonpré P, Balestra C, Hemelryck W, Buzzacott P, Lafère P.

Authors: Zheng Yiyuan , Lu Yanyu , Jie Yuwen , Fu Shan
Published: April 2017

BACKGROUND: The minimum flight crew on the flight deck should be established according to the workload for individual crewmembers. Typical workload measures consist of three types: subjective rating scale, task performance, and psychophysiological measures. However, all these
measures have their own limitations. To reflect flight crew workload more specifically and comprehensively within the flight environment, and more directly comply with airworthiness regulations, the Workload Function Distribution Method, which combined the basic six workload functions, was
proposed.METHODS: The analysis was based on the different conditions of workload function numbers. Each condition was analyzed from two aspects, which were overall proportion and effective proportion. Three types of approach tasks were used in this study and the NASA-TLX scale was
implemented for comparison.RESULTS: Neither the one-function condition nor the two-function condition had the same results with NASA-TLX. However, both the three-function and the four- to six- function conditions were identical with NASA-TLX. Further, the significant differences
were different on four to six conditions. The overall proportion was insignificant, while the effective proportions were significant.DISCUSSION: The results show that the conditions with one function and two functions seemed to have no influence on workload, while executing three
functions and four to six functions had an impact on workload. Besides, effective proportions of workload functions were more precisely compared with the overall proportions to indicate workload, especially in the conditions with multiple functions.Zheng Y, Lu Y, Jie Y, Fu S. Flight

Emergency Highway Landings in General Aviation and the Possible Role of Media Reports
Authors: Holzman Emily , de Voogt Alex
Published: April 2017

BACKGROUND: To examine the causes and factors of airplane landings on highways and the dangers to occupants of vehicles on the ground.METHODS: The U.S. National Transportation Safety Board online database provided 133 accidents involving a highway landing dating from
2000 to 2013. Supplemental information was sought in online media archives, which reported on 53 of these accidents. Collisions with highway-related objects, other options for landing, and witness accounts were added categories extracted from the narrative statements and media reports.RESULTS:
Highway landings occur mostly due to mechanical failures, ineffective preflight or in-flight planning, and fuel exhaustion, in addition to a lack of alternate landing options for a pilot of a fixed-wing aircraft. Most of the landings (N = 108) lead to minor or no injuries at all. A
significant proportion of 7 out of 19 collisions with powerlines resulted in a fatality, as opposed to other types of accidents. Collisions with motor vehicles (N = 29) caused minor (N = 23) and serious (N = 2) injuries to people on the ground. Main online media archives
covered less than half of all accidents (39.8%).DISCUSSION: While highway landings are not a recommended landing alternative, mitigation strategies should include a focus on avoiding powerlines and vehicles on the ground. Unfortunately, online media archives are not yet a consistent
source of information for general aviation accidents.Holzman E, de Voogt A. Emergency highway landings in general aviation and the possible role of media reports. Aerosp Med Hum Perform. 2017; 88(5):497–499.
Prepartum Lying Behavior of Holstein Dairy Cows Housed on Pasture through Parturition
Authors: Rice Christa , Eberhart Nicole , Krawczel Peter
Published: April 2017

Utilizing pasture-based systems may increase cow comfort during late gestation and calving as it lacks the constraints of confinement housing. The objective of this study was to quantify lying behavior and activity of Holstein dairy cows housed on pasture during the 6 d before calving. Sixteen Holstein dairy cows were moved to pasture 3 weeks before their projected calving date. Data loggers were attached 14 d prior to projected calving date. Behavior was evaluated 6 d before calving for all cows (n = 16) and 6 h prior to calving for a subset of cows (n = 6) with known calving times. Data loggers recorded at 1-min intervals to determine lying time (h/d and %/h), lying bouts (n/d and n/h), lying bout duration (min/bout), and steps (n/d and n/h). A repeated measures analysis of variance with contrasts was performed to determine if lying behaviors and activity differed between baseline and day or hour of interest. Lying time was greater 6 d prior to calving compared to the day of and before calving. Cows had longer lying bouts 6 d prior to calving compared to day of calving. Cows spent less time lying in the hour before calving compared to 6 h prior to parturition. The lack of change in behavior and activity during the 7 d prior to calving may indicate that pasture provided an adequate environment for cows during the prepartum period but did not impact cow welfare in the hours leading up to calving.

Published: April 2017

This paper proposes an optimal solution to large-scale Flexible Manufacturing System (FMS) scheduling problems under availability constraints based on Timed Petri Nets (TPNs). First a decomposition method of TPNs is proposed, then a mathematical model is derived based on their properties. The mathematical model is built to determine the optimal firing sequence of TPN transitions to minimize the total manufacturing time. The resulting firing sequence of TPN transitions is used to generate the manufacturing system supervisor operated by TPN and digital controllers. Several numerical examples and comparative studies are provided in this paper in order to prove the new approach’s efficiency.

Published: April 2017

Since its introduction in 2010, self-referenced spectral interferometry (SRSI) has turned out to be an analytical, sensitive, accurate, and fast method for characterizing the temporal profile of femtosecond pulses. We review the underlying principle and the recent progress in the field of SRSI. We present our experimental work on this method, including the development of self-diffraction (SD) effect-based SRSI (SD-SRSI) and transient-grating (TG) effect-based SRSI (TG-SRSI). Three experiments based on TG-SRSI were performed: (1) We built a simple TG-SRSI device and used it to characterize a sub-10 fs pulse with a center wavelength of 1.8 μm. (2) On the basis of the TG effect, we successfully combined SRSI and frequency-resolved optical gating (FROG) into a single device. The device has a broad range of application, because it has the advantages of both SRSI and FROG methods. (3) Weak sub-nanojoule pulses from an oscillator were successfully characterized using the TG-SRSI device, the optical setup of which is smaller than the palm of a hand, making it convenient for use in many applications, including sensor monitoring the pulse profile of laser systems. In addition, the SRSI method was extended for single-shot characterization of the temporal contrast of ultraintense and ultrashort laser pulses.

Published: April 2017

This study demonstrates the rapid and label-free detection of Interleukin-6 (IL-6) using carbon nanotube micro-arrays with aptamer as the molecular recognition element. Single wall carbon nanotubes micro-arrays biosensors were manufactured using photo-lithography, metal deposition, and etching techniques. Nanotube biosensors were functionalized with 1-Pyrenebutanoic Acid Succinimidyl Ester (PASE) conjugated IL-6 aptamers. Real time response of the sensor conductance was monitored with increasing concentration of IL-6 (1 pg/mL to 10 ng/mL), exposure to the sensing surface in buffer solution, and clinically relevant spiked blood samples. Non-specific Bovine Serum Albumin (BSA), PBS samples, and anti-IgG functionalized devices gave similar signatures in the real time conductance versus time experiments with no significant change in sensor signal. Exposure of the aptamer functionalized nanotube surface to IL-6 decreased the conductance with increasing concentration of IL-6. Experiments based on field effect transistor arrays suggested shift in drain current versus gate voltage for 1 pg and 1 ng of IL-6 exposure. Non-specific BSA did not produce any appreciable shift in the Ids versus Vg suggesting specific interactions of IL-6 on PASE conjugated aptamer surface gave rise to the change in electrical signal. Both Z axis and phase image in an Atomic Force Microscope (AFM) suggested unambiguous molecular interaction of the IL-6 on the nanotube-aptamer surface at 1 pg/mL concentration. The concentration of 1 pg falls below the diagnostic gray zone for cancer (2.3 pg-4 ng/mL), which is an indicator of early stage cancer. Thus, nanotube micro-arrays could potentially be developed for creating multiplexed assays involving cancer biomarker proteins and possibly circulating tumor cells all in a single assay using PASE functionalization protocol.
Virtual Reality for Research in Social Neuroscience
Authors: Parsons Thomas , Gaggioli Andrea , Riva Giuseppe
Published: April 2017

The emergence of social neuroscience has significantly advanced our understanding of the relationship that exists between social processes and their neurobiological underpinnings. Social neuroscience research often involves the use of simple and static stimuli lacking many of the potentially important aspects of real world activities and social interactions. Whilst this research has merit, there is a growing interest in the presentation of dynamic stimuli in a manner that allows researchers to assess the integrative processes carried out by perceivers over time. Herein, we discuss the potential of virtual reality for enhancing ecological validity while maintaining experimental control in social neuroscience research. Virtual reality is a technology that allows for the creation of fully interactive, three-dimensional computerized models of social situations that can be fully controlled by the experimenter. Furthermore, the introduction of interactive virtual characters—either driven by a human or by a computer—allows the researcher to test, in a systematic and independent manner, the effects of various social cues. We first introduce key technical features and concepts related to virtual reality. Next, we discuss the potential of this technology for enhancing social neuroscience protocols, drawing on illustrative experiments from the literature.

Published: April 2017

A sulphated tin ion-exchanged montmorillonite (SO42−/Sn-MMT) was successfully prepared by the ion exchange method of montmorillonite (MMT) with SnCl4, followed by the sulphation. This catalysis was applied as a solid acid catalyst for the heterogeneous catalytic transformations of xylose and xylan into furfural in the bio-based 2-methyltetrahydrofuran/H2O biphasic system. These prepared catalysts were characterized by X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), temperature programmed desorption of ammonia (NH3-TPD), pyridine adsorbed Fourier transform infrared spectroscopy (Py-FTIR), element analysis (EA) and Brunauer-Emmett-Teller (BET) method. Their catalytic performance for xylose and xylan into furfural was also investigated. The reaction parameters such as the initial xylose and xylan concentration, the amounts of catalyst, the organic-to-aqueous phase volume ratio, the reaction temperature and time were studied to optimize the reaction conditions. Results displayed that SO42−/Sn-MMT contained both Brønsted acid and Lewis acid sites, and SO42− ions were contributive to the formation of stronger Brønsted acid sites, which could improve the reaction efficiency. Reaction parameters had significant influence on the furfural production. The substitution of water by the saturated NaCl solution in the aqueous phase also had an important effect on the xylose and xylan conversion. The highest furfural yields were achieved up to 79.64% from xylose and 77.35% from xylan under the optimized reaction conditions (160 °C, 120 min; 160 °C, 90 min). Moreover, the prepared catalyst was stable and was reused five times with a slight decrease (10.0%) of the furfural yield.
