Workers in the Crowd: The Labour Market Impact of the Online Platform Economy

We compare individuals engaged in online crowdwork against workers in traditional occupations from the United States and Europe, investigating the determinants of access into crowd employment and the nature of the deterioration of salary conditions and job quality characterizing these markets. We do so by matching responses from comparable working conditions surveys, and controlling for most individual and socio-economic characteristics affecting pay. We find that most differences in earnings are largely unexplained by the ability of individuals, and that labor in crowdwork is vastly under-utilized.
The synergetic effect of knowledge management and business model innovation on firm competence

Purpose The purpose of this paper is to provide a systematic review of the linkage between knowledge management, business model innovation and firm competence. The study attempts to summarize a few important and essential issues which future research should address. Design/methodology/approach Researchers have conducted an extensive review of the literature covering 50 journals from various databases like Scopus, ProQuest and Emerald. A total of 88 articles from 1997 to 2018 on knowledge management and business model innovation were selected and analyzed. Findings The study found that the integration of knowledge management and business model innovation leads to a sustainable competitive advantage. The relationship between knowledge management, business model innovation and firm competence seems to be fragmented because of various meaning and conceptualizations. The study endeavors to examine the relationship between the dimensions (knowledge acquisition, knowledge conversion, knowledge dissemination, knowledge application and knowledge reuse) of knowledge management and business model innovation (value proposition, assets and capabilities, revenue and cost architecture and actors in business networks). The study highlights that chief knowledge officers have a vital role to play in enhancing knowledge management orientation of a company so that knowledge regarding new ways of value creation and value capture is heard within an organization. Research limitations/implications This study provides a distribution schema of knowledge management and business model innovation articles based on different search criteria by highlighting different future research avenues. The study is believed to serve as a basis and be a valuable tool for researchers to understand the current and future scenarios about knowledge management and business model innovation. Researchers also acknowledge the limitations of this study with regard to exclusive search criteria, which might affect its generalizability. Practical implications The study argues that better knowledge sharing between departments could benefit value creation and therefore drive the organization toward business model innovation which would automatically boost firm competence. The study has made an attempt to highlight the role of Chief Knowledge Officer with regard to business model innovation. Therefore, the proposed model developed in this review will help the organization to better understand the role of knowledge management and business model innovation. Originality/value This is one of the first systematic reviews of knowledge management and business model innovation which provides a detailed understanding of the past and future research on the two.
Overriding Tradition? An Initial Exploration of the Intersection of Institutional and Disciplinary Cultures from the Student Perspective

Prior work has highlighted differences in the nature and structure of knowledge across various academic disciplines. These differences manifest themselves in a number of ways, including teaching and learning practices, methods of assessing student learning, and roles and expectations of students and teachers – all of which influence and shape the culture of a specific discipline within an institution. While prior work has focused on disciplinary and institutional cultures separately, little work has been done to understand how these two cultures intersect to create a unique culture within each academic department. In this exploratory study, we draw on Hofstede’s dimensions of national cultures to better understand the intersections of institutional and disciplinary cultures in shaping students’ experiences. We situate the study within two different engineering disciplines: electrical and computer engineering (ECE) and industrial and systems engineering (ISE). Semi-structured interviews were conducted with 59 undergraduate students from six universities across the U.S. Our cross-institutional analysis reveals variations in student perceptions that suggest ways in which local cultures may influence approaches to learning and perceptions of teaching practices locally, indicating that local cultures may override traditional characterizations of engineering disciplines. These emerging findings suggest that changes at departmental and institutional levels can significantly impact students’ experiences of disciplinary practices and values and challenge the idea of engineering culture as monolithic and immovable. As a result, these local cultures can – and should – play a transformative role in revolutionizing students’ development as engineers.
Profile-guided scope-based data allocation method

The complexity of High Performance Computing nodes memory system increases in order to challenge application growing memory usage and increasing gap between computation and memory access speeds. As these technologies are just being introduced in HPC supercomputers no one knows if it is better to manage them with hardware or software solutions. Thus both are being studied in parallel. For both solutions, the problem consists in choosing which data to store on which memory at any time. In this paper we present a linear formulation of the data allocation problem. Moreover, we propose a new profile-guided scope-based approach which reduces the data allocation problem complexity, thus enhancing the precision of state of the art analyzes. Finally we have implemented our method in a framework made of GCC plugins, dynamic libraries and python scripts, allowing to test the method on several benchmarks. We have evaluated our method on an INTEL Knight's Landing processor. To this aim we have run LULESH, HydroMM, two hydrodynamic codes, and MiniFE, a finite element mini application. We have compared our framework performance over these codes to several straight-forward solutions: MCDRAM as a cache, in hybrid mode, in flat mode using numactl command and existing AutoHBW dynamic library.
Factors predisposing to stone migration from the gallbladder into the common bile duct

Endoscopic retrograde cholangiopancreatography (ERCP), followed by laparoscopic cholecystectomy (LC), has an important role in the treatment of gallstone cholangitis. The aim of the present study was to investigate the optimal timing of LC, and factors that predispose early recurrence in patients who undergo ERCP for common bile duct (CBD) stones.
Development of design specifications for strengthening deteriorated concrete bridge elements using externally applied FRP sheets

El refuerzo a flexion de vigas de hormigon armado con FRP (fibre-reinforced polymer) se ha convertido, en la ultimas decadas, en uno de los metodos mas utilizados para aumentar la resistencia de una estructura. Este fenomeno puede ser dividido en dos grupos: el primero que se manifesta por la presencia de una elevada tension cerca de las extremidades del refuerzo de FRP; el otro que esta causado por la formacion de fisuras intermedias en la viga. Para prevenir este fenomeno, muchos autores propusieron modelos para calcular el maximo valor de carga que la viga reforzada puede aguantar. Este trabajo esta dividido en dos partes. En la primera, se ha estudiado el fenomeno del despegue del material compuesto (FRP) de una viga en hormigon armado. Han sido considerados la manera de fallo llamada “end debonding” y otra conocida con el nombre de “intermediate crack induced debonding”. Se han creado tres diferentes bases de datos reuniendo los datos experimentales encontrados en la literatura. El primero representa ensayos de hormigon con FRP ensayados para examinar el despegue entre FRP y hormigon. La segunda base de datos reune vigas en hormigon armado que fallan por end debonding. El ultimo incluye diferentes tipologias de experimentos sobre vigas para analizar el fenomeno del intermediate crack induced debonding. Estos datos se han dividido en diferentes grupos para analizar la diferencia entre los tipos de materiales y entre las diferentes maneras de aplicacion.
Patients with schizophrenia after the acute ward: Seven years' service utilization and clinical course

What characterizes the use of treatment services and global functioning of patients with schizophrenia in sectorized psychiatry? Are there relationships between patient characteristics, treatment characteristics, and outcome? Eighty-one patients with DSM-IIIR schizophrenia treated at a short-term unit serving a defined catchment area were followed up after 7 years. Seventy-four of the 76 patients alive at follow-up participated in the study. Global functioning was measured with the Health Sickness Rating Scale. The patients had mainly been treated as outpatients with short hospitalizations. The level of outpatient contact was high, and most used antipsychotic medication throughout the follow-up period. Global outcome was poor in spite of demographic characteristics associated with good outcome in schizophrenia. The uniformly poor outcome indicates that the overall organization of treatment services did not suit these patients with schizophrenia. The treatment needs of patients with later onsets of psychos.
Towards More Context and Discourse in Grammar Instruction

This paper first discusses why the sentence-level drills still being used extensively in the teaching of grammar to second language learners have not been successful. What follows is a presentation of an innovative approach; namely, using context and discourse to present and practice grammar in more authentic and effective ways. Statement Of The Problem At the 2007 TESOL Convention in Seattle, Washington, I was surprised to see how many of the ESL/EFL textbooks being displayed and sold in the book exhibits still use decontextualized sentence-level exercises for most of each grammar lesson or unit. In such grammar exercises, learners are typically asked to do something resembling one of the rather mechanical drill types below:
Dental caries prevalence in individual tooth in primary and permanent dentition among 6-12-year-old school children in Shimla, Himachal Pradesh

Background: Prevalence of dental caries not only varies according to age, gender, and arch but also according to the involvement of individual tooth. The study on individual tooth will help in providing incremental dental care and reducing burden of dental caries in this group of population. Objective: To find out the prevalence of dental caries in individual tooth among 6-12-year-old school children in Shimla city, Himachal Pradesh. Materials and Methods: This study was conducted among 1,200 school-going children over a span of 5 months from 11 government schools in Shimla city, in the state of Himachal Pradesh in India. Examination was performed using a mouth mirror and blunt sickle-shaped explorer under natural light, according to World Health Organization (WHO) oral health survey 1997. Results: Females were having higher prevalence of dental caries than males of the same age-group in both primary and permanent dentition (79.3% vs. 74.9%). First molars were most affected with dental caries than other teeth in both the dentitions (78.69% and 48.93%, respectively). Dental caries prevalence was high in mandibular arch than in the maxillary arch i.e. (80.0% vs. 77.38%) in permanent dentition and (51.3% vs. 46.56%) in deciduous, dentition respectively. Statistically, this difference was significant (Fischer's exact test P Conclusion: High prevalence of dental caries among government school children in Shimla city is a cause of concern. There is utmost necessity of regular periodic check-up, application of preventive measures, and treatment modalities as soon as teeth erupt in the oral cavity.
Effect of exogenous adiponectin on myocardial fibrosis in mice models with myocardial fibrosis

Background: Myocardial fibrosis is closely associated with cardiac dysfunction, arrhythmia, and sudden cardiac death. A model of myocardial fibrosis induced by isoprenaline was used to determine the influence of exogenous adiponectin on myocardial fibrosis. Materials and Methods: A total of 30 mice were equally and randomly divided into three groups as follows: isoproterenol (ISO, n = 10), adiponectin and isoproterenol (APN + ISO, n = 10), and sham (n = 10). ISO (7.5 mg/kg/day) was injected intraperitoneally (i. p.) in the ISO group and APN + ISO group for three consecutive days to establish a model of myocardial fibrosis; normal saline was injected in the sham group. From day 4, adiponectin was injected (10 μg/kg/day; i. p.) in the APN + ISO group for 32 days; normal saline was injected in ISO and sham groups for 32 days. Five weeks later, mice were sacrificed, and myocardial tissue was dyed by Sirius Red to observe the collagen morphology. The collagen volume fraction was calculated. Protein and messenger RNA (mRNA) expression of type-I and type-III collagen in the myocardium was detected by reverse transcription-polymerase chain reaction and western blotting, respectively. Results: Type-I collagen in myocardial interstitial tissue was significantly increased in the ISO group. Collagen in myocardial interstitial tissue in the ISO + APN group was decreased significantly compared with the ISO group. Expression of type-I collagen mRNA in ISO and ISO + APN groups was significantly higher than that in the sham group (3.01 ± 0.78, 2.32 ± 0.82 vs. 1, respectively; P < 0.01). Expression of type-I collagen mRNA in the ISO + APN group was significantly lower than that in the ISO group (2.32 ± 0.82 vs. 3.01 ± 0.78, respectively; P < 0.01). Expression of type-III collagen mRNA in the ISO group, and ISO + APN group was significantly higher than that in the sham group (2.39 ± 0.70, 1.62 ± 0.57 vs. 1, respectively; P < 0.01). Expression of type-III collagen mRNA in the ISO + APN group was significantly lower than that in the ISO group (1.62 ± 0.57 vs. 2.39 ± 0.70, respectively; P < 0.01). Expression of type-I collagen protein in the myocardium in the ISO + APN group was significantly higher than that in the sham group (0.73 ± 0.19 vs. 0.28 ± 0.15, respectively; P < 0.001), but it was significantly lower than the expression of type-I collagen protein in the ISO group (0.53 ± 0.17 vs. 0.73 ± 0.19, respectively; P < 0.001). Conclusions: Supplementation with exogenous adiponectin can inhibit myocardial fibrosis induced by ISO.
Think talk write with pictured cards on human digestive system: impact of critical thinking skills

The critical thinking skill is one of the high-level thinking skills needed by students in the teaching and learning process. This research aimed to determine the effect of Think Talk Write (TTW) based picture cards on students’ critical thinking skills of class VIII on human digestive system material in SMP Negeri 6 Ketungau Tengah. The research was a quantitative approach using the quasi-experimental design. The populations were all eighth-grade students of SMP Negeri 6 Ketungau Tengah consisting of 41 students. The samples were VIII A class total of 22 students for the experimental class and VIII B class total of 19 students for the control class. Instruments used essay questions to measure critical thinking skills. The data obtained were analyzed using descriptive and inferential analysis using the t-test. The descriptive analysis results in the TTW learning model showed that there was an increase in the mean value of students' critical thinking skills from pre-test to post-test by 66.34% and the conventional learning by 33.30%. The results of the inferential analysis show that there is a significant learning effect on students' critical thinking skills (p: 0,000 < 0.05). The mean value of the TTW learning model is better than the conventional learning. It is recommended that teachers be able to implement the TTW learning model based on picture cards in science learning to improve students' critical thinking skills.
Epidemiological Study on Equine Gastrointestinal Helminth Parasites in Mekelle, North Ethiopia

A cross-sectional examination of 384 fecal samples was conducted from July 2016 up to November 2016 to determine the prevalence of gastrointestinal helminth infections of equines in Mekelle, North Ethiopia. Out of total fecal samples examined 196 fecal samples were taken from horses, 164 from Donkeys and the rest 24 from Mules. The prevalence of gastro intestinal helminths was 41.6% as detected by coprological examination. Coprological examination revealed that the prevalence in horses was 33.7%, in donkeys 51.8% and in mules 37.5%. There is significant difference (p 0.05) in prevalence of GIT helminth was noticed between sexes. However, a significant difference (p < 0.05) was noticed between the age groups, between different body conditions, feeding status, history of colic and frequency of deworming. The study revealed that Equines in the study area are infected with a range of heminths, which are representatives of the important equine pathogenic parasites found in Ethiopia.
Systemic Risk Contagion in FX Market: A Frequency Connectedness and Network Analysis

In this study, we analyse systemic risk contagion between a set of most actively traded currencies (EURO, JPY, GBP, AUD, CAD and CHF) by application of VAR based frequency connectedness proposed by Barun&#237;k and K&#345;ehl&#237;k. By using this novel approach, we gauge foreign exchange (FX) market connectedness in 200&#8208;day frequency band using spectral representation of variance decompositions of VAR and identify directional spillovers between the most actively traded foreign exchange rates. Dynamics of the overall spillover index reveals that the index capture well&#8208;known financial stress incidents properly. Finally, network topology of directional spillovers between currency pairs is provided for visulalization interconnectedness between them.
Students Participation and Perception in Threaded Online Discussion

Many terms used for distance learning utilizing internet namely, on-line learning, elearning, internet-enable learning, virtual learning, virtual classroom or web based learning. One of the uses of it is for online discussion using online threaded portal. Using online threaded discussion, the study aims to find out the participation and perspective of the students in using online media to conduct a discussion. The research chooses Muhammadiyah University of Malang’s students as the participants. The students’ participation was determined by the level of interactivity of the students during discussion, yet the perspective was compiled through the questionnaire administered. This study applied quantitative method to seek the students’ participation by adopting Thomas’ framework to count the level of interaction in each message and further this data will be explained qualitatively. The result of the study found that the percentage of the students commenting on threaded online discussion is still low. Out of 20, only 9 commented in the first group whereas the second group from 23 students only 20 who join the discussion. Furthermore, the majority of the students hold negative perception toward threaded
Early to Mid-Term Follow-Up Outcomes of Percutaneous Closure of Atrial Septal Defects Using Recent Generation Devices: a Single-Center Experience

Background and Objectives This study aimed to describe our early to mid-term experience with transcatheter atrial septal defect (ASD) closure using the Occlutech Figulla® Flex II device (FSO), Gore® Cardioform septal occluder (GSO), and Amplatzer® septal occluder (ASO) after they were first approved in Korea in 2014, and to compare the three aforementioned kinds of ASD closure devices. Methods Between September 2014 and August 2016, 267 patients underwent transcatheter ASD closure in our institution. Baseline characteristics, hemodynamic features, comorbidities, and procedural success and complication rates were analyzed retrospectively. The unpaired Student t-test or variance analysis was used in the statistical analysis. Results The FSO was most commonly used (n=152, 56.9%), followed by the ASO (n=98, 36.7%) and GSO (n=17, 6.4%). Baseline characteristics and hemodynamic features were similar between the devices, except that the defect size and pulmonary flow-to-systemic flow ratio were lower in the GSO group than in the other groups. Overall, the procedural success rate remained at 100%, and major complication rate was <1%. No late complication occurred during the follow-up. Conclusions The FSO and GSO are feasible, safe options for use in transcatheter ASD closure, and they are comparable to the ASO.
Understanding the effects of human capital on economic growth

Er is veel consensus in de literatuur met betrekking tot het belang van onderwijs, dat wil zeggen menselijk kapitaal. Zowel voor de economie als voor de maatschappij als geheel heeft onderwijs grote waarde: het genereert geldelijke omzet, maar ook sociaal rendement. Dit proefschrift onderzoekt het belang van onderwijs, en dus menselijk kapitaal, voor het faciliteren van snellere economische groei. Ten eerste laat ik de veronderstelling los dat een gewerkt uur een constante hoeveelheid arbeidsdiensten oplevert. Pas afgestudeerden wijken van eerdere cohorten af met betrekking tot de arbeidsdiensten per gewerkt uur die zij leveren. Deze vintage effecten van menselijk kapitaal spelen een grote rol in de verklaring van het verschil in de trans-Atlantische productiviteitsgroei tussen 1995 en 2005. Ten tweede kijk ik opnieuw naar het vermogen van menselijk kapitaal om externaliteiten te genereren door middel van technologische vooruitgang en adoptie van technologie. Om potentiele externaliteiten op te sporen, gebruik ik een methode die menselijk kapitaal met de totale factor productiviteit verbindt. Externaliteiten worden gegenereerd door tertiair opgeleide mensen en hangen in hoge mate af van het niveau van de technologische ontwikkeling van een land. Ten derde onderzoek ik internationale “spill-overs” van menselijk kapitaal. Ik analyseer de impact van migratie op het menselijk kapitaal van het thuis land en kom tot de conclusie dat landen met een hogere emigratie van vakbekwame werknemers een snellere groei in hun kennisintensieve industrieen laten zien. Dit suggereert een ‘brain gain’ in plaats van ‘brain drain’.
The Voynich Manuscript - An Elegant Enigma

Abstract : In spite of all the papers that others have written about the manuscript, there is no complete survey of all the approaches, ideas, background information and analytic studies that have accumulated over the nearly fifty- five years since the manuscript was discovered by Wilfrid M. Voynich in 1912. This report pulls together all the information the author could obtain from all the sources she has examined, and to present it in an orderly fashion. The resulting survey will provide a firm basis upon which other students may build their work, whether they seek to decipher the text or simply to learn more about the problem.
