Instrumented activity and semiotic mediation: two frames to describe the conjecture construction process as curricular organizer

We document part of the process through which conjectures produced by students, with the aid of the dynamic geometry software Cabri, when they solve proposed geometric problems, become a curriculum organizer in the classroom. We first focus on characterizing students’ instrumented activity recurring to utilization schema (Rabardel, 1995, in Bartolini Bussi and Mariotti, 2008), and then describe the teacher’s content management through which the ideas produced by the students become key elements of knowledge construction.
The Assessment of Research Quality in UK Universities: Peer Review or Metrics?

This paper investigates the extent to which the outcomes of the 2008 Research Assessment Exercise in the UK, determined by peer review, can be explained by a set of quantitative indicators. Three cognate units of assessment are examined in detail: business and management, economics and econometrics, and accounting and finance. The main finding is that each of the three components of research activity (namely, research output, esteem and research environment) is highly correlated with various quantitative indicators. A further finding is that the judgement of the Research Assessment Exercise panels was biased in favour of Russell Group universities. There is also evidence of bias by the economics and econometrics panel. The results support the use of quantitative indicators in the research assessment process, particularly a journal quality index. Requiring the panels to take bibliometric indicators into account should help not only to reduce the workload of panels but also to mitigate the problem of implicit bias.
Extracting Relationships by Multi-Domain Matching

In many biological and medical contexts, we construct a large labeled corpus by aggregating many sources to use in target prediction tasks. Unfortunately, many of the sources may be irrelevant to our target task, so ignoring the structure of the dataset is detrimental. This work proposes a novel approach, the Multiple Domain Matching Network (MDMN), to exploit this structure. MDMN embeds all data into a shared feature space while learning which domains share strong statistical relationships. These relationships are often insightful in their own right, and they allow domains to share strength without interference from irrelevant data. This methodology builds on existing distribution-matching approaches by assuming that source domains are varied and outcomes multi-factorial. Therefore, each domain should only match a relevant subset. Theoretical analysis shows that the proposed approach can have a tighter generalization bound than existing multiple-domain adaptation approaches. Empirically, we show that the proposed methodology handles higher numbers of source domains (up to 21 empirically), and provides state-of-the-art performance on image, text, and multi-channel time series classification, including clinical outcome data in an open label trial evaluating a novel treatment for Autism Spectrum Disorder.
Abrasive flow machining: A review on new developed hybrid AFM process

The abrasive flow machining technique uses a self-deforming tool, an abrasive laden media that is passed back and forth in the passage geometry of the hollow workpiece with the assistance of two hydraulically operated cylinders placed opposite to each other. The material is removed by abrasion generating finer surfaces in the area where flow is restricted. But this method has a low material removal rate. As the time advances, various variants of AFM have been developed by different researchers to increase the productivity and improve the surface finish. Thus a combination of AFM and its process variants were developed to increase material removal rate and surface finish. This article provides a comprehensive review of recent developments in the process variants of AFM and the respective media.
Carcass and non-carcass component characteristics of lambs fed with cassava wastewater dregs in replacement of corn

The objective was to evaluate the effect of the substitution (0, 33, 66 and 100%) of corn by cassava wastewater dregs on carcass characteristics and non-carcass components of crossbred Santa Ines lambs. Forty male sheep, uncastrated with an average initial body weight of 20 ± 1.87 kg and five months of age, were used. These were housed in individual pens in a randomized block design with four treatments and ten repetitions and slaughtered after 70 days of confinement. Quadratic effect (P < 0.05) was observed for the empty body weight (EBW), hot carcass weight (HCW) and cold carcass weight (CCW) and carcass compactness index (CCI), with maximum points of 36.14, 19.45, 20.20 and 0.31 kg cm-1 for the replacement level of corn for cassava wastewater dregs, 50.0, 53.84, 54.04 and 45.45% respectively. There was also an effect (P < 0.05) on the weights of the rumen and “Buchada”, with maximum points of 0.909 and 6.25 kg per replacement level, 49.11 and 51.29% respectively. As for retail cuts, only the efficiency of the leg was altered (P < 0.05), having a linear increase while the other variables were not affected. Cassava wastewater dregs can be used in full as an alternative food in the diet of feedlot lambs without harming the main carcass characteristics and non-carcass components.
Readout electronics for LumiCal detector

The development of readout electronics for the luminosity detector (LumiCal) at the ILC, performed within the EUDET consortium, is presented. The LumiCal design impose several challanging constraints and requirements on the readout electronics system. The readout should work for a wide range of sensor capacitances, up to about 100 pF, and for a very wide dynamic range of input charge, from 2 fC to 10 pC. In addition it should be fast enough to separate events from the subsequent bunch crossings, dissipating very low power. The proposed LumiCal readout channel architecture comprises of two main ASICs i.e., the preamplifiershaper and the analog-to-digital converter ASIC. For later integration in the complex multichannel readout system several peripherial circuits (DACs, differential I/O, reference voltages) are also necessary. The above mentioned components of the readout system were designed, the prototypes were produced and subsequently tested. The prototypes were fabricated in 0.35 µm CMOS technology. The prototypes of all circuits are fully functional and the quantitative measurements performed so far confirm a good agreement with simulations. In this report the design and measurements results of the produced prototype ASICs are discussed.
Wild common bean in the Central Valley of Costa Rica: ecological distribution and molecular characterization

Wild common bean in the Central Valley of Costa Rica: ecological distribution and molecular characterization. This work offers an update on the distribution of wild common bean in Costa Rica, its ecology and molecular characterization. To date 22 populations have been discovered in four watersheds around the Central Valley, usually in man-made habitats (often sides of coffee plantations), under varying conservation status (from protected to threatened). Molecular characterization indicates that the wild common bean belong to the Mesoamerican gene pool. Different markers indicate an increased genetic diversity in some wild populations, and allow to hypothesize the presence of gene flow and introgression from cultivated materials.
Three Tier Indoor Localization System for Digital Forensics

 Abstract — Mobile localization has attracted a great deal of attention recently due to the introduction of wireless networks. Although several localization algorithms and systems have been implemented and discussed in the literature, very few researchers have exploited the gap that exists between indoor localization, tracking, external storage of location information and outdoor localization for the purpose of digital forensics during and after a disaster. The contribution of this paper lies in the implementation of a robust system that is capable of locating, tracking mobile device users and store location information for both indoor and partially outdoor the cloud. The system can be used during disaster to track and locate mobile phone users. The developed system is a mobile application built based on Android, Hypertext Preprocessor (PHP), Cascading Style Sheets (CSS), JavaScript and MATLAB for the Android mobile users. Using Waterfall model of software development, we have implemented a three level system that is able to track, locate and store mobile device information in secure database (cloud) on almost a real time basis. The outcome of the study showed that the developed system is efficient with regard to the tracking and locating mobile devices. The system is also flexible, i.e. can be used in any building with fewer adjustments. Finally, the system is accurate for both indoor and outdoor in terms of locating and tracking mobile devices.
Equality of opportunities for young Italian workers

The duality of the labour market in Italy is a dramatic social and economic issue. Not only the youth unemployment rate is one of the highest in Europe (39.7% in 2014), but also the quality of job contracts is very low for young, compared to elder cohorts. Moreover, Italy is perceived as a low-mobility country, where individual outcomes depend signi cantly on initial conditions and parental background. This paper exploits the heterogeneity of job contracts to investigate whether and how circumstances beyond individual control affect the labour market outcomes of young labour force, not only as the probability of employment, but also as the type of job contract achieved. Results confirm that the role of predetermined conditions is very strong, in particular gender and the region of origin, but also parental labour status. The relative effects and significances of circumstances changed their magnitude over time.
Emojinating : Representing Concepts Using Emoji

Emoji system does not currently cover all possible concepts. In this paper, we present the platform Emojinating, which has the purpose of fostering creativity and aiding in ideation processes. It lets the user introduce a concept and automatically represents it, by searching for existing emoji and generating novel ones. The system combines the exploration of semantic networks with visual blending, and integrates data from EmojiNet, ConceptNet and Twemoji. To evaluate the system in terms of production efficiency and output quality, we produced emoji for a set of 1509 nouns from the New General Service List. The results show a coverage of 75% of the list.
Media, Gender and Peace Initiatives in Northeast India: An Analysis

Northeast part of India has always been in the news and public discourse for ongoing conflicts and violent events occurring from time to time. In such a context, the role media plays for resolution of such conflicts and restoration of peace cannot be ignored. Years-long, this part of the country has been suffering due to conflicts of various sorts and this has led to the loss of human lives and property of unaccountable proportion. Moreover, there are instances of such conflicts later resulting in civil wars and larger humanitarian crisis with people of one community perpetrating violence on the other. In such situations, women who are considered to be the most vulnerable among all have suffered the most. In this backdrop, the paper is a content analysis of six newspapers published from three selected states from the northeastern part of India. It looks at the way media, more specifically the print reacts to conflict situations and peace processes in northeast India. Apart from that, the paper also reflects upon the perception of the journalists towards the role print media is playing in conflict situations in Northeast India.

Los resultados magnetoestratigraficos se correlacionan con datos de 7 sitios cercanos del RGS, con 6 sitios de la SP ycon fechamientos K-Ar disponibles. Un pozo geotermico exploratorio de la Comision Federal de Electricidad en la SP permitio larecuperacion de muestras hasta los 1361 m, asi como el estudio paleomagnetico de 8 muestras de nucleo distribuidas entre 93 my 1358-1361 m. En la secuencia volcanica de RGS de las secciones de Huaxtla, Paso de Guadalupe y Lazo, asi como en los domosy secuencias lavicas de la SP, se documentan polaridades normales (N), intermedias (I) y reversas (R). Las tres secuenciasestudiadas en el RGS son de alrededor de 800 m de espesor, incluyen una secuencia ignimbritica basal (R), los basaltos SanCristobal (principalmente R), riolitas y flujos de cenizas del grupo Guadalajara (principalmente R), la ignimbrita San Gaspar (N),flujos basalticos y un domo riolitico (N). La secuencia de la SP descansa sobre una secuencia andesitica e incluye una riolita, losbasaltos San Cristobal (R), riolitas y flujo andesitico del grupo Guadalajara (R), tobas de flujo de cenizas, riolitas de precaldera, latoba Tala (R, I) y los depositos lacustres de intra-caldera. Los basaltos San Cristobal representan la unidad mas antigua de laTMVB, con edades entre 11 y 8 Ma. Este intervalo corresponde a un cron de polaridad normal en la escala de tiempo de polaridadgeomagnetica, lo que contrasta con la polaridad reversa dominante observada en el RGS y la SP. La polaridad normal de laignimbrita San Gaspar ha sido fechada en 4.7-4.8 Ma y constituye un horizonte marcador en la region de Guadalajara. Estaignimbrita y las unidades del grupo Guadalajara (con fechas de 5.2-5.5 Ma) son asignadas al cron reverso Gilbert, con la ignimbritaSan Gaspar posiblemente correspondiendo al subcron normal Thevera (4.59-4.79 Ma). La secuencia silicea de la SP representa lareciente actividad volcanica en la region y se asigna al cron Brunhes.
The Geography of Natural Resources, Ethnic Inequality and Development

We study whether the spatial distribution of natural resources across different ethnic groups within countries impede spatial inequality, national economic performance, and the incidence of armed conflict. By providing a theoretical rent-seeking model and analysing a set of geocoded data for mines, night-time light emissions, local populations and ethnic homelands, we show that the distribution of resources is a major driving factor of ethnic income inequality and, thus, induces rent-seeking behaviour. Consequently, we extend the perspective of the resource curse to explain cross-country differences in economic performance and the onset of civil conflicts. We show that the inequality in the spatial distribution of resource endowments within countries drives the curse of natural resources, not the resources per se.
Spatially dependent Rabi oscillations : An approach to sub-diffraction-limited coherent anti-Stokes Raman-scattering microscopy

We present a theoretical investigation of coherent anti-Stokes Raman scattering (CARS) that is modulated by periodically depleting the ground-state population through Rabi oscillations driven by an additional control laser. We find that such a process generates optical sidebands in the CARS spectrum and that the frequency of the sidebands depends on the intensity of the control laser light field. We show that analyzing the sideband frequency upon scanning the beams across the sample allows one to spatially resolve emitter positions where a spatial resolution of 65 nm, which is well below the diffraction limit, can be obtained.
Business Case for Corporate Transparency: Evidence from Kenya

With increasing trend of corporate scandals and corporate failure, stakeholders are demanding access to information, transparency and accountability. In response to these demands, corporate governance guidelines all over the world prescribe for corporate transparency and disclosure of information especially among public listed firms. Drawing from agency theory and stakeholder theory, we argue that corporate boards have a responsibility to disclose material information to stakeholders in order to facilitate decision making and hence improve firm performance. This study investigates business case of corporate transparency in Kenya. Applying Fixed Effects regression model on data from 42 listed firms in Nairobi Securities Exchange for the period 2005-2010, we found that indeed corporate transparency has a positive and significant effect on firm performance. The results have important policy implications on corporate disclosures in Kenya. Keywords: Corporate Transparency, Accountability, Corporate Governance, Kenya.

It highlights the degree of acceptance TOC has gained in practice. In light of the continued paucity of empirical support for the technique, it reports the results of an empirical analysis of TOC adopters. The study results support several of the elements of TOC as significantly related to business unit performance.
Analysis of Angklung Sound Intensity as a Acoustic Instrument

The purpose of this study was to analysis of angklung sound intensity. The research method is using angklung musician 2 octaves. Each consists of two tube tone that sounded from the tone of G to G ', length and diameter of the tube every tone becomes independent variable, while intensity of the sound produced becomes dependent variable. Sound intensity is measured using a Sound Level Meter is placed with a constant distance. The result showed that G tone was a low tone which had a frequency of 49.5 Hz, first tube had 21.6 cm length and 4.1 cm diameter, second tube had 10.1 cm length and 3.4 cm diameter produced the sound intensity of 90.7 dB. G’ tone was a high tone which had a frequency of 99 Hz, first tube had 10 cm length and 3 cm diameter, second tube had 5.5 cm length and 2.1 cm diameter produced the sound intensity of 99.1 dB. It can be concluded that the higher the frequency, the greater the intensity of the sound produced. The shorter tube length and the smaller tube diameter, the greater the intensity of the sound. ©2016 JNSMR UIN Walisongo. All rights reserved.
A study of seeking guidance and support coping strategy of cancer patients

This study on seeking guidance and support coping strategy was conducted with 120 cancer patients of Lok Nayak Jay Prakash Hospital, New Delhi. The study was based on 2×2×2 factorial design experiment with two conditions of mode of treatment (chemotherapy and surgery), two types of extroversion (extrovert and introvert), and two types of neuroticism (emotionally stable and emotionally unstable). Thus, there were eight groups of subjects with 15 subjects in each group. Coping Response Inventory and Eysenck Personality Inventory was used to collect data from all subjects. The statistical analysis of data revealed that seeking guidance and support coping of extrovert cancer patients was significantly more than that of introvert cancer patients; and seeking guidance and support coping of emotionally stable cancer patients was significantly more than that of emotionally unstable cancer patients. The interaction between the mode of treatment and extroversion, and another interaction between extroversion and neuroticism was also significant. Key words: Personality, coping, guidance and support, extroversion, neuroticism, cancer patients.
Credit rationing or overlending? An exploration into financing imperfection

ABSTRACT Small and new firms are deemed to be unable to obtain sufficient bank loans. This idea finds a strong theoretical support in credit rationing theory. However, this is vigorously challenged by De Meza and Webb (1987, 2000) suggesting that firms can benefit from an excess of credit, i.e. overlending. Credit rationing or overlending? The contribution of this empirical article is twofold: to our knowledge, it is the first to make an attempt in measuring the relative importance of these two types of financing imperfection and to explore factors leading to one or the other. We exploit a rich panel data set on the access to bank credit for new French businesses during the mid-1990s. Our results show that credit rationing was not highly spread among French new firms. The story told by De Meza and Webb (1987) appears to be a much more realistic model. In addition, we identify factors, linked to the starter, the project or the industry, that are closely associated with credit rationing and/or overlending. Most factors enter into a consistent relation: when they are positively (negatively) associated with credit rationing, they are negatively (positively) associated with overlending.
Multimodal All Optical Technique for the Quantification of Dynamic Stress

A multimodal optical technique namely; near infrared diffuse optical spectroscopy (NIR: DOS) and mid infrared imaging (MIRI) is applied as a non-invasive, in-vivo tool for monitoring the vascular status of flexor pollicis brevis (thenar muscle of hand), and the physiological changes that occur during physical exercise. A technique helps in monitoring the changes in tissue blood oxygen saturation, and, information of the thermodynamics of heat dissipation during prolonged physical exercise. The proposed methodology is likely to provide insight into muscle physiology, therapeutic response and treatment. A new generation of excitation sources, detection technologies, and smart algorithms have renewed interest of using multi-spectral imaging techniques in the emerging field of biomedical diagnostics [1-3]. In this paper we present a multimodal optical technique based on steady state diffuse optical spectroscopy (SSDOS: 650-850 nm) for studying the changes in tissue blood oxygen saturation and mid infrared imaging (MIRI: 2-12 µm) for studying the thermodynamics of heat dissipation by monitoring the changes in the spatial distribution of temperature during prolonged physical exercise. The understanding of tissue oxygenation status and the behaviour of the physiological parameters derived from thermometry may provide useful insight into muscle physiology, therapeutic response and treatment.
