Authors: Chethan R. , Patil R.K. K. , Halappa B.
Published: April 2018

A study was carried out to know the response of organic, integrated and conventional farming systems on the diversity of soil meso and macro arthropod populations in the cotton inter cropped with groundnut and pigeonpea at MARS, UAS, Dharwad during kharif -2015-16. The organic farming system has recorded highest meso and macro arthropod population of 21.35 per 100 g of soil and 42.00 per pitfall trap respectively. Cotton intercropped with groundnut has recorded higher population of meso and macro arthropods (15.50 /100 g of soil and 41.26/ pitfall trap, respectively). The seasonal abundance of soil arthropods was high in October (25.89/100g of soil) and least in December (5.78/ 100g of soil) months. The diversity of soil arthropod populations assessed on the Shannon’s index of below ground arthropod populations recorded was highest in organic farming (0.61) and least in conventional farming (0.51) system. Hence, the organic farming system increases abundance and diversity of soil organisms and soil fertility, and it adds large amounts of organic residue inputs, which in turn increases the biological activity in soil.

Published: April 2018

Genetic diversity among 30 chickpea genotypes was assessed for yield attributing and traits related to mechanical harvesting during rabi 2016-17 under both rainfed and irrigated conditions as separate experiments. The genotypes were grown in randomized block design (RBD) with three replications. Genetic diversity study grouped 30 chickpea genotypes into five different clusters under both the tested environments. Days to 50 per cent flowering followed by days to maturity and 100 seed weight contributed maximum towards diversity under rainfed as well as irrigated conditions. Inter cluster average D2 values stretched between 7.42 and 20.11 under rain fed condition, while it was slightly higher and varied from 8.64 to 28 under irrigated condition. The most divergent clusters were IV and V under both the situations. The traits that are suitable for mechanical harvesting particularly, height of the first pod and plant height contributed more (8.3 per cent and 8.1 per cent respectively) towards the genetic divergence under irrigated than under rainfed condition (3 per cent and 5.5 per cent respectively). While the angle of the primary branch couldn’t show any influence on the divergence under both the tested environments. Promising genotypes with suitable traits for mechanical harvesting besides having yield advantage are‘NBeG 780’, ‘NBeG 857’, ‘NBeG 47’, ‘NBeG 863’ and ‘BG 3061’ of cluster I under rainfed and cluster II under irrigated, ‘GBM 2’ of cluster II in rainfed and cluster I in irrigated, ‘ICCL 85213’ and ‘NBeG 865’ of cluster III under rainfed, ‘DBGV 3104’ of cluster I under rainfed and ‘GL 12021’ of cluster V under both rainfed and irrigated are suggested for utilization in the crossing programs to breed varieties of chickpea for high yield with amenability to combine harvesting.

Authors: Meyer Jill M. , Kashubeck-West Susan , Portela Lindsay
Published: April 2018

Two of the more commonly known measures of coping in rehabilitation and counseling are the Ways of Coping Questionnaire (WCQ; Folkman & Lazarus, 1988; Lazarus & Folkman, 1984) and the Brief COPE (BC; Carver, 1997).

Purpose: The present study had two goals: (a) to examine the revised structures of these measures to determine the reliability and validity when used in a sample of individuals with latedeafness, and (b) to examine differences in coping style in individuals with late-deafness across race, ethnicity, gender, age, socioeconomic status (SES), level of hearing loss, communication style, and employment.

Methods: An online, quantitative survey was used to collect data from participants (N = 277) who completed the WCQ, the BC, measures of life satisfaction, and a demographic questionnaire.

Results: The two revised factors from the WCQ correlated as expected with life satisfaction, demonstrating convergent validity. However, discriminant validity was not found with this measure. Four of the six revised factors of the BC correlated as expected with life satisfaction, indicating acceptable convergent validity. In addition, discriminant validity was found with this measure. A few differences in coping were found on the basis of age, SES, and gender.

Conclusion: The results suggest that the BC, with the revised factors, is a solid measure of coping in individuals with late-deafness.

The objective of this research was to examine the effectiveness of coconut water with various egg yolk concentrations in maintaining the viability of epididymal spermatozoa of crossbreed cattle preserved at 5oC. Five testis with epididymides of crossbreed cattle were obtained from slaughterhouse. Epididymal spermatozoa was collected by the combination of slicing, flushing and tissues pressure methods of cauda epididymides with saline solution (0.9% NaCl). Collected-spermatozoa was equally divided in volume into four tubes and diluted with lactose extender containing 20% egg yolk (control), 90% coconut water + 10% egg yolk (CWEY10), 85% coconut water + 15% egg yolk (CWEY15), and 80% coconut water + 20% egg yolk (CWEY20), repectively. Diluted-spermatozoa was stored in refrigerator at 5oC. Quality of dilutedspermatozoa including percentages of motile spermatozoa (MS), live spermatozoa (LS), spermatozoa with intact plasma membrane (IPM) were evaluated every day during four days of storage. Data were analyzed by using completely randomized design with four treatments and five replicates. Means were compared with significant difference test at 0.05 significant level. Results of this study showed that mean of spermatozoa concentration, percentage of MS, percentage of LS, percentage of spermatozoa abnormal, and percentage of IPM of crossbreed cattle fresh epididymal spermatozoa were 1,414 million cell/ml, 72%, 85%, 9%, and 90%, respectively. At day-4 of the storage, percentages of MS, LS, and IPM of control (43, 52.2, 59.2%) and CWEY20 (42, 52, 59%) were significantly (P<0.05) higher than CWEY10 (33, 45.4, 52.8%) and CWEY15 (37, 50, 54.6%). In conclusion, lactose and CWEY20 extenders could be maintaining the quality of epidydimal spermatozoa of crossbreed cattle for three days preservation at 5oC and two days for CWEY10 and CWEY15.

In this study, we introduce the five-parameter
doubly-truncated exponentiated inverse Weibull distribution, where the
truncation points are known, and consider its basic properties. Formulas for
moment generating function, characteristic function, mean, variance and
kurtosis of the distribution are derived. Estimates of parameters are obtained
using traditional estimation methods; maximum likelihood, least squares and
weighted least squares. Furthermore, in order to give a lower bound for the
standard errors of estimates of parameters, a Fisher information matrix is provided.
Finally, a Monte-Carlo simulation study is designed and conducted to evaluate
the performances of obtained estimators of parameters.
Temporal stability of within-field variability of total soluble solids of grapevine under semi-arid conditions: a first step towards a spatial model
Authors: Verdugo-Vásquez Nicolas , Acevedo-Opazo César , Valdés-Gómez Héctor , Ingram Ben , García de Cortázar-Atauri Iñaki , Tisseyre Bruno
Published: April 2018

Aims: This work focuses on the study of the intra- and inter-annual Temporal Stability of Within-Field Variability (TSWFV) of Total Soluble Solids (TSS) as an estimate of grape maturity.
Methods and results: The experiment was carried out between 2009 and 2015 in four fields located in the Maule Valley, Chile, under irrigated conditions. Each field corresponded to a different cultivar (namely Cabernet-Sauvignon, Chardonnay, Sauvignon blanc and Carménère), and data collection ranged over two to four years depending on the field. A regular sampling grid was designed within each field, and TSS was measured at each site of the grid on different dates (from veraison to harvest). A Kendall test (W) was used to analyse the TSWFV of TSS between all dates for each cultivar and season. A Spearman’s rank correlation coefficient (rs) was used to analyse the relationships between each sampling date and the date of harvest considered as the reference. Results of the study highlighted high within-field variability in TSS. The W test showed significant intra- and inter-annual TSWFV, and rs values showed a high and significant correlation between sampling dates.
Conclusion: These results are of interest for precision viticulture since, under the conditions of the experiment, the spatial patterns of the TSS maps obtained 40 days before harvest remain the same until harvest. Therefore, early target sampling of TSS may provide a good estimate of the spatial variability of grape maturity at harvest.
Significance and impact of the study: The inter-annual stability of the TSS spatial patterns makes it possible to propose a simple empirical spatial model that allows estimation of TSS values for the whole field using only one reference measurement, provided that historical data are available.
Phenology of Tempranillo and Cabernet-Sauvignon varieties cultivated in the Ribera del Duero DO: observed variability and predictions under climate change scenarios
Authors: Ramos Maria Concepción , Jones Gregory V , Yuste Jesús
Published: April 2018

Aim: This research examined relationships between grapevine phenology and climate in the Ribera del Duero DO (Spain). The observed varieties included Tempranillo, the main variety planted in the region, and Cabernet-Sauvignon.Methods and Results: Phenological events for stages C (budbreak), I (bloom), M (véraison) and N (maturity) were analyzed for 2004-2015. Dormant period chilling and late winter heating requirements to initiate growth were evaluated and accumulated temperature (growing degree days-GDD) prior to each phenological event and in between events were examined for the role they play in influencing growth timing. The results were then used to examine future phenological changes due to climate change using eight models integrated in the Coupled Model Intercomparison Project (CMIP5) and for two Representative Concentration Pathways (RCP) scenarios – RCP4.5 and RCP8.5 – for 2030, 2050, and 2070. Accumulated temperatures after March 20th become important for initiating phenology and are strongly correlated to all growth events. The influence of water availability between budbreak and bloom and between bloom and véraison on phenological timing was also confirmed.Conclusions: The projections showed that for the RCP4.5 emission scenario, budbreak is predicted earlier by approximately 2 days for 2030, 3 days for 2050 and 5 days for 2070, while bloom is predicted to be 3 to 8 days earlier and véraison 6 to 19 days earlier for the same time periods. For the RCP8.5 emission scenario, budbreak is modeled to take place about 3 days, 5 days and 9 days earlier, respectively for 2030, 2050 and 2070. Bloom is predicted to occur about 5, 10 and 16 days earlier; véraison is predicted earlier by 10 days for 2030, 19 days for 2050, and 28 days for 2070. Maturity and the timing of harvest could be up to 23 days earlier under the RCP4.5 emission scenario and up to 35 days earlier under the RCP8.5 emission scenario. Compared to Cabernet-Sauvignon, Tempranillo exhibited greater phenological sensitivity to temperature changes in the observed time period that is likely to continue into the future with greater changes to earlier growth events projected. This sensitivity could be problematic for the region due to the variety’s historic importance and points to the need to examine adaptive measures that can help growers to respond to projected changes in climate.Significance and impact of the study: The projected climate changes in the future indicate the potential for significant changes in the phenology of Tempranillo in the Ribera del Duero DO, Spain. Given that this variety has the largest contribution and importance in this region, these changes could have impacts on wine quality, indicating the need of establishing strategies to reduce or mitigate the impact from future changes in climate.

Authors: A. Kandrashina Elena , S. Zotova Anna
Published: April 2018

The creation of new management methods that guarantee sustainable economic development in the long-term perspective is impossible without the overall analysis of the existing methods and system elements of enterprise management. Such analysis should take into account the influence of external and internal environment. Most of Russian organizations functioning at the market are characterized by low degree of flexibility and adaptability to the changes at the market and by traditional ways of management which do not correspond to the modern market conditions and it does not allow them to develop perfectly. The article defines the main components of the enterprise sustainable development and offers the matrix model of changes assessment on the basis of sustainable development criterion.Thus, the general aim of the article is to form theoretical and methodical basis for management mechanism aimed at sustainable development of the enterprise, the mechanism that meets the current demands and global trends of economy development. The main methodical instrument used for the enterprise position assessment is the system of matrix coordinates. The choice of the matrix form is due to the fact that matrices are the main tool for strategic positioning of enterprises and the choice of strategic solutions in conditions of multiplicity of parameters through which the expected and actually obtained results are formalized and measured.

Published: April 2018

This paper seeks to propose rational water use indicators for public schools in Recife, Brazil. The methodology consists of a cadastral survey, the use of questionnaires, and identification of leakage in the hydro-sanitary facilities. The results indicate that even though water consumption is not as high as pointed out in the literature, the schools still present a considerable amount of physical water losses, in addition to having a low perception regarding the rational use of water. Based on these results, this study supports the development and application of water conservation actions within the school environment.

The role played by geologists and mining engineers in the consolidation of prehistoric archeology in Spain (1860-1970)
Authors: Ayarzagüena Sanz M.
Published: April 2018

Geoarchaeology, as a scientific discipline, took its first steps in the last quarter of the twentieth century. However, its background lies in the very origins of prehistoric archaeology, from 1860 onwards. In Spain the evolution of Geoarchaeology and the studies that preceded it has kept pace with the rest of Europe. Spain was the third country in the world, after France and Britain, in which the international scientific community recognized the existence of prehistoric industry; similarly, when Geoarchaeology, as an independent scientific discipline, began to be institutionalized in Europe, Spain was not left behind. In this study we will examine the development of prehistoric studies in Spain from the mid-nineteenth century to the late twentieth, showing the effects that geological studies have had on them.

Published: April 2018

The sedimentary infill bearing the archaeological and anthropological record of the Ossuary Gallery (the Sidrón cave) shows high complexity in both sediment types and their spatial distribution in the cavity. The main factors that govern this complexity are the episodic and highly energetic nature of the recorded sedimentary infill units and the irregular geometry of the gallery itself, which significantly compartmentalized areas of deposition. Briefly, all types of typical allochthonous detrital material deposits in karst environments are represented in the Ossuary Gallery; from well-sorted fine-grained sediment facies representative of backswamp (clays of the unit O) or slackwater (Unit IV), to poorly-sorted coarse-grained deposits corresponding to mudflows and debris flows (Unit II and Unit III base), and typical channel facies composed of laminated sands and silts (units I and II). The bone and lithic remains are concentrated in unit III. The source area is above the Ossuary Gallery, at the intermediate or higher karst levels. The input of archeological material to the Ossuary Gallery was triggered in high energy episodes in association to flood events and / or storms.

Published: April 2018

The Cierro Cave (Fresno, Ribadesella, Asturias) is a karst cavity located in the west bank of the Sella river and developed in the Carboniferous limestone of the Asturian Massif of the Cantabrian Range (northern Iberian Peninsula). This cave contains an important sedimentary, archaeological and palaeontological record of the Upper Pleistocene and Early Holocene with abundant technological remains (lithic and bone industries) and bone remains of mammals and others vertebrates. The archaeological record starts with a probably Middle Palaeolithic level, followed by a complete sequence of the Upper Paleolithic, with a Lower Magdalenian level clearly identified and dated, and ends with levels of the Late Upper Magdalenian/Azilian and the Mesolithic forming three shell middens. The stratigraphic sequence consists of fourteen levels grouped in two litostratigraphic units with very different sedimentary characteristics studied by geoarchaeological methods. The lower unit is characterized by the significant presence of siliceous sands and silts while the upper unit is formed by three anthropic shell middens cemented by carbonates. This paper analyzes the lithostratigraphic sequence and shows the results of the granulometric, mineralogical, edaphic and radiometric analysis. These results allows us to interpret precisely the lithostratigraphy of the deposits and the sedimentary and diagenetic processes responsible for their formation and evolution. In addition, the radiocarbon dates obtained allow us to place the upper levels of the clastic sequence in the GS 2b and the lower shell midden in GI 1 and GS 1 at the end of the Upper Pleistocene, while the upper shell midden would be located in the Boreal cronozona in the Early Holocene.
Depositional and anthropic processes in the Holocene record of the Can Sadurní cave (Begues, Barcelona, Spain): microstratigraphic contributions
Authors: Bergadà M.M. , Cervelló J.M. , Edo M. , Antolín F. , Martínez P.
Published: April 2018

The geoarchaeological and microstratigraphic study of the Can Sadurní cave sequence (Begues, Barcelona) reveals the presence of detrital and anthropogenic depositional processes, alternating at certain stages. These influenced the location of the diagenetic processes. The cultural sequence of the site ranges from Epipaleolithic to Late Roman Empire, with some chronocultural interruptions. During the Epipaleolithic and Mesolithic, solifluction processes were responsible for sedimentation. From the Neolithic, mass wasting and colluvial processes were dominant. Dense flows are distinguished mainly during the Cardial Early Neolithic and Early Postcardial. This type of contribution is also present to a lesser extent during the Postcardial Middle Neolithic, Late Neolithic/Chalcolithic and Early Bronze Age. Non-laminated colluvial inputs appear in the rest of the sequence. These episodes alternate with periods of stability, in which the rate of detrital sedimentation is lower or almost non-existent. This is replaced by the presence of in situ stabling areas during the Epicardial and Early Postcardial Neolithic, although evidence is detected from the Cardial Early Neolithic. Associated with these contexts, hydromorphic processes are accentuated leading to the formation of vivianite -an iron phosphate mineral- typical of a reducing medium with high organic matter.
Despeckling of Carotid Artery Ultrasound Images with a Calculus Approach
Authors: Latha S. , Samiappan Dhanalakshmi
Published: April 2018

Background: Carotid artery images indicate any presence of plaque content, which may
lead to atherosclerosis and stroke. Early identification of the disease is possible by taking B-mode
ultrasound images in the carotid artery. Speckle is the inherent noise content in the ultrasound images,
which essentially needs to be minimized.

Objective: The objective of the proposed method is to convert the multiplicative speckle noise into
additive, after which the frequency transformations can be applied.

Method: The method uses simple differentiation and integral calculus and is named variable gradient
summation. It differs from the conventional homomorphic filter, by preserving the edge features
to a great extent and better denoising. The additive image is subjected to wavelet decomposition
and further speckle filtering with three different filters Non Local Means (NLM), Vectorial
Total Variation (VTV) and Block Matching and 3D filtering (BM3D) algorithms. By this approach,
the components dependent on the image are identified and the unwanted noise content existing
in the high frequency portion of the image is removed.

Results & Conclusion: Experiments conducted on a set of 300 B-mode ultrasound carotid artery
images and the simulation results prove that the proposed method of denoising gives enhanced results
as compared to the conventional process in terms of the performance evaluation methods like
peak signal to noise ratio, mean square error, mean absolute error, root mean square error, structural
similarity, quality factor, correlation and image enhancement factor.

Authors: Eroğlu Mehmet E. , Bayraktepe Dilek E. , Polat Kamran , Yazan Zehra
Published: April 2018

Background:

Electrochemical oxidation mechanism and electrochemical determination of meloxicam
(M), an anti-artrithtis agent, were investigated by cyclic voltammetry and square wave adsorptive
stripping voltammetry, respectively.

Objective: In this study, we aimed to investigate the electrochemical redox mechanism and develop a
nano-sensor for sensitive, fast and selective analysis of meloxicam.

Methods:

In this study, the three-electrode system was used for all voltammetric measurements. Firstly,
the graphene content of GR/CPE sensor was changed in the range of 1.67% to 6.68%. Then, the surface
characterization of modified electrode was carried out by using Electrochemical Empedance Spectroscopy
and Surface Electron Microscopy methods. Some analytical parameters, such as pH, accumulation
potential and accumulation time were optimized and by using optimum parameters, calibration study
was established.

Results:

The GR/CPE with a graphene content of 3.33 % was found to have the best voltammetric signal
with a linear working range of 0.1–10 µM. The sensitivity of the quantitative voltammetric method
towards M is fairly good with an LOQ of 0.0088 μmol/L and LOD of 0.0026 µmol/L.

Conclusion:

The optimum pH, accumulation time and accumulation potential were found to be 2.0,
150s and 0.0 V, respectively. The height of the voltammetric signal obtained with the GR/CPE electrode
was stable with a 4.0 % deviation for a period of not shorter than 1 months.
HCVS: Pinpointing Chromatin States Through Hierarchical Clustering and Visualization Scheme
Authors: Noureen Nighat , Fazal Sahar , Qadir Muhammad Abdul , Afzal Muhammad Tanvir
Published: April 2018

Background:

Specific combinations of Histone Modifications (HMs) contributing towards
histone code hypothesis lead to various biological functions. HMs combinations have been utilized by
various studies to divide the genome into different regions. These study regions have been classified as
chromatin states. Mostly Hidden Markov Model (HMM) based techniques have been utilized for this
purpose. In case of chromatin studies, data from Next Generation Sequencing (NGS) platforms is being
used. Chromatin states based on histone modification combinatorics are annotated by mapping them to
functional regions of the genome. The number of states being predicted so far by the HMM tools have
been justified biologically till now.

Objective:

The present study aimed at providing a computational scheme to identify the underlying
hidden states in the data under consideration.

Methods: We proposed a computational scheme HCVS based on hierarchical clustering and
visualization strategy in order to achieve the objective of study.

Results:

We tested our proposed scheme on a real data set of nine cell types comprising of nine
chromatin marks. The approach successfully identified the state numbers for various possibilities. The
results have been compared with one of the existing models as well which showed quite good
correlation.

Conclusion:

The HCVS model not only helps in deciding the optimal state numbers for a particular data
but it also justifies the results biologically thereby correlating the computational and biological aspects.
EFFECTS OF PEDAGOGICAL APPROACHES and PRACTICES FOR SUSTAINABLE DEVELOPMENT IN EARLY CHILDHOOD EDUCATION: A RESEARCH REVIEW
Authors: Rajawat Pushpita
Published: April 2018

The relative effectiveness of different pedagogical approaches and pedagogies in early childhood has raised substantial debate. While the other are associated with the acquisition of basic skills and knowledge and some of them are associated with socio-emotional development and problem-solving abilities. In general, research revealed both positive and negative effects of pedagogical approaches, without favouring specific pedagogical approaches over mainstream ones. However, it is important to note that research evidence and studies considering the same approaches in the same context are very limited. On the other hand, specific pedagogical practices are found to enhance child development, including high-quality interactions involving sustained-shared thinking methods, play-based learning, scaffolding, as well as a combination of staff- and child initiated activities. Research impacts pedagogy and pedagogical practices in the sense that research findings can inform policy makers and practitioners on best practices and what works best in enhancing staff performance, process quality and child development. Research on pedagogy and practices is usually not conducted at the national level, but focuses on particular programmes. So, research review has been used as a guide or manual to provide pedagogical guidance for Early Childhood Education (ECE) staff not only in India but also worldwide. The main focus of the study is that how of the best pedagogical practices and approaches across the country can be useful and implemented in early childhood education

New scientific spirit and new epistemology: a More poietic point of view of education and knowledge
Authors: Lanzarini Joice Nunes , Probst Melissa
Published: April 2018

ABSTRACT The positivist science model has been influencing Education for more than three centuries. The belief that guides such model separates the intelligible world, as the most important, which, deals with science, intelligence and the brain from the sensitive world, one-step down in importance, which, deals with sensitive experiences and emotions.  The application of such epistemological concepts helped to build the current education model. The current education conceptions indicate an urgency in seeking, not only new methodology theories, but also the construction of an educational concept more connected to modern times demands.  The work of Gaston Bachelard is considered one of the most important regarding the twentieth century science revolution when it comes to a new creative poetic construction with several points of view. The following paper tries, briefly, to use the ideas presented by Bachelard in his book “The new scientific spirit” and relate them to the proposal of a poetic point of view regarding education and knowledge by setting a dialogue with other authors who developed their considerations from  Bachelard as well.   Keywords: Education.

A filosofia como atitude crítica da produçao de si na educação tecnológica
Authors: Vandresen Daniel Salésio , Gelamo Rodrigo Pelloso
Published: April 2018

O objetivo desse artigo é realizar um diagnóstico da educação tecnológica utilizando como ferramenta as noções de biopolítica e ontologia do presente desenvolvidos por Michel Foucault. A partir disso, problematizamos a educação tecnológica dos Institutos Federais analisando sua concepção de ensino baseada na noção de trabalho como princípio educativo. Constata-se que a educação tecnológica não tem pensado a vida para além da formação profissional ou, melhor, tem se preocupado apenas com a parte da vida que é determinada pela sua condição cotidiana da utilidade e do trabalho. Por fim, desenvolve-se o conceito de atitude crítica para pensar uma prática filosófica que dá forma à impaciência da liberdade e permite a resistência aos saberes de sujeição próprios da tecnicidade biopolítica.   Palavras-chave: Biopolítica; Ontologia de nós mesmos; Filosofia; Educação tecnológica.   ABSTRACT The objective of this article is to make a diagnosis of technological education by using, as a tool, the current notions of biopolitics and ontology developed by Michel Foucault. Thus, the authors problematized the technological education of the Institutos Federais analyzing their conception of education based on the notion of work as an educational principle. It is clear technological education has not thought about life beyond vocational training or, rather, has been concerned only with the part of life that is determined by its daily use and work. Finally, the concept of critical attitude is developed to consider a philosophical practice that gives form to the impatience of freedom and allows the resistance to servitude knowledge inherent to biopolitical technicity.   Keywords: Biopolitics; Oneself Ontology; Philosophy; Technological education.   RÉSUMÉ L'objectif de cet article est de faire un diagnostic de l'éducation technologique en utilisant comme outil les notions de biopolitique et d'ontologie du présent développé par Michel Foucault. De ce fait, nous problématisons l'éducation technologique des Institutos Federais en analysant leur conception de l'éducation fondée sur la notion de travail en tant que principe pédagogique. On peut voir que l'éducation technologique n'a pas pensé à la vie au-delà de la formation professionnelle, mais plutôt qu'elle ne concerne que la partie de la vie qui est déterminée par sa condition quotidienne d'utilité et de travail. Enfin, le concept d'attitude critique est développé pour penser une pratique philosophique qui donne forme à l'impatience de la liberté et permet la résistance à la connaissance de l'assujettissement propre à la technicité biopolitique.   Mots-clés: Biopolitique; L'ontologie de nous-mêmes; Philosophie; L'éducation technologique.DOI: http://dx.doi.org/10.22169/revint.v12i27.1293

Perceived control and scarcity appeals
Authors: Lee Seon Min , Ryu Gangseog , Chun Seungwoo
Published: April 2018

We examined how individuals would respond to scarcity appeals when they felt low (vs. high) in personal control. We proposed that scarcity would be an effective way to compensate for loss of control because it symbolizes distinctiveness, stimulates urgency, and offers an opportunity
to obtain resources. Results from 2 experiments confirmed our prediction. In Study 1, participants (64 Korean college students) indicated a greater intention to purchase a limited-edition product when they perceived low (vs. high) control. In Study 2, participants (228 Korean college students)
who perceived low (vs. high) control chose a larger-sized product more often when the product used an only-time frame than when it did an any-time frame. Our findings contribute to the literature by introducing a compensatory paradigm to scarcity effects and identifying its promotional use
as a new mechanism for compensatory control.

Rebung bambu ampel (Bambusa vulgaris Schrad. ex Wendl.) memiliki kandungan nutrisi, namun di samping itu juga rebung mengandung unsur anti nutrisi yang membahayakan kesehatan yaitu kandungan hidrogen sianida (HCN) sehingga dibutuhkan cara pengolahan yang benar agar kandungan sianida dapat dikurangi bahkan dapat dihilangkan sebelum dikonsumsi. Pada penelitian ini rebung diolah dengan cara perendaman dan air mengalir yang dilanjutkan dengan variasi waktu perebusan. Hasil penelitian ini menunjukan bahwa penurunan kadar sianida terendah yaitu pada perendaman dan perebusan selama 5 menit sebesar 68 ppm sedangkan penurunan kadar sianida yang paling besar terjadi pada kombinasi perlakuan rebung yang dicuci dengan air mengalir dan perebusan selama 120 menit sebesar 656,33 ppm. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa waktu perebusan mempengaruhi kadar sianida rebung, semakin lama waktu perebusan kadar sianida semakin menurun.Kata kunci : Sianida, Rebung, Bambu Ampel (Bambusa vulgaris Schrad. ex Wendl.)
