A NEGLECTED EARLY CONTRIBUTION TO GROWTH THEORY

This paper reexamines an important early contribution to the growth literature highlighted in 2000 by Cannon in the American Economic Review: “The production function in allocation and growth: A synthesis” by Marvin Frankel in 1962. First this contribution provides a formal proof in the continuous time framework of trajectories that are not provided by Frankel and Cannon. Second it shows that in this framework poverty traps are possible while it was not detected by these authors. RESUME Ce document revient sur une contribution ancienne en théorie de la croissance remise au gout du jour en 2000 par Cannon dans l’American Economic Review: “The production function in allocation and growth: A synthesis” de Marvin Frankel en 1962. Ce document présente d’une part la preuve d’existence de solutions en temps discret absente dans les deux contributions. Et, d’autre part, démontre que dans ce cadre il existe un piège à pauvreté qui n’a pas été détecté par ces deux auteurs.
Education systems implementation success model

Originally developed for delivering distance learning programs, e-education systems in their current forms are powerful, web-based information systems with capabilities that match Enterprise Resource Planning (ERP) systems. By carrying out their deployments on an enterprise-level basis, many Higher Education Institutions (HEI) are able to leverage on their powerful functionalities and ERP-like integrative capabilities to put together academic and administrative systems (Twigg 2002). This study is proposing that it may no longer relevant to still evaluate e-education systems as only educational technologies in view of the current implementation environment where new forms of e-education systems are now information systems of strategic relevance in many HEI (Moul 2002). E-education systems should therefore be studied as: mainstream information systems, i.e. within the paradigms of information systems evaluation research and no longer as educational technology or innovation. This study looks into information systems success model that can be developed to explain and predict the success of e-education systems implementation. It identifies constructs to measure e-education systems implementation success; investigates the appropriate dependent variable as a proxy for e-education systems implementation success and finally develops and validates the model. The findings from this research, showed that the ‘organizational IS continuance’ construct is a viable proxy for information systems implementation success and the model developed can be equally applied and generalizable across different stakeholder groups.
International Congress of Chemical and Process Engineering CHISA 2012 25 – 29 August 2012 , Prague , Czech Republic Automation of industrial serial processes based on finite state machines

An automation solution based on finite state machine (FSM) for a flow measurement testing unit is proposed. This FSM was able to automate not only the execution of one test but the whole sequence of tests. Commercial software and hardware tools were employed. As a result an unattended, continuous, high productivity and low cost operation was achieved. This solution can be applied to automate other serial and batch processes. © 2012 Published by Elsevier Ltd. Selection under responsibility of the Congress Scientific Committee (Petr Kluson)
Number 138 Children , War and World Disorder in the 21 st Century : A Review of the Theories and the Literature on Children ’ s Contributions to Armed Violence

Young populations, and particularly young males, have been attributed a proclivity to aggression and unrest that puts societies at risk. Theories about the dangers of a demographic ‘youth bulge’ inform public and policy debates about the predictors of violent conflict, as evidenced most recently in the World Bank’s World Development Report for 2007. This paper evaluates the validity and utility of claims linking youth bulges to civil conflicts by reviewing different literatures concerning naturalist ideas of young humans’ innate aggression and cognitive incompetence as well as environmentalist ideas of environmental stimuli, processes of socialisation, and the dialectical relationship of structural conditions and human agency. This review finds that the moral panic propagated by youth bulge theorists is too often based on only one form of influence on human development and action, whether an aspect of environment, personal experience, or individual traits. A more cogent analysis must integrate the highly complex and dynamic processes involved in cognition and behaviour and aim to develop theories that take account of the social power, ideational and structural forms, and emotional and cognitive processes that young people experience and draw on in times of war. Theories of causality that fail to account for this complexity obscure understanding of the many ways in which young people and conflict may be linked.
In vivo analgesic and anti-inflammatory properties of the aqueous extract of Pistacia atlantica Desf. from Morocco

The present study analyses the pharmacological activity in vivo models of the aqueous extract obtained from Pistacia atlantica Desf of Morocco. The plant selected for this study have been used in traditional medicine in Morocco for the treatment of various diseases that are considered as inflammation in nature, e.g. arthritis, rheumatism, fever, and related inflammatory diseases. The result of this study showed that the aqueous extract of Pistacia atlantica Desf. lacked toxicity, but exhibited a high analgesic effect in writhing Test and in tail immersion Test suggesting the induction of a peripheral and central analgesic response. The aqueousextract of this plant also exhibited an anti-inflammatory action inhibiting the rat paw edema induced by carrageenin and experimental trauma. We can conclude that the aqueousextractof Pistacia atlantica Desf. Possesses potential anti-inflammatory activities, supporting the traditional application of this plant in treating various diseases associated with inflammation and pain in Morocco.
Metastasis associated in colon cancer 1 ( MACC 1 ) : at the crossroads of cancer metastasis and drug resistanced

Metastasis and drug resistance are the greatest contributors to cancer related death. Thus, identification of the effective targets becomes the essential prerequisite for individualized diagnosis and therapy. MACC1 is a transcription factor that promotes tumor metastasis and drug resistance. In this review, the discovery of MACC1 is briefly presented. We reviewed MACC1 accelerates metastasis in multiple types of cancer through promoting the HGF/c-Met signaling pathway, EMT process, lymphangiogenesis and vasculogenic mimicry. MACC1 induces drug resistance by enhancing metabolic shift. In addition, we envisioned that the utility of MACC1 as a potential prognostic biomarker and a promising therapeutic target for suppressing cancer metastasis and drug resistance.
Persona driven agile development Build up a vision with personas , sketches and persona driven user stories

In the beginning of a user centered agile development process, three important elements have to be defined. 1) A software product with a defined set of features, 2) the intended usage context and 3) the future software product user. The clear definition of these elements right from project start will lead to a more accurately developed software product. A combination of well-known tools like “personas” and sketches of the context of use as well as requirements as persona driven user stories make a comprehensive basis. During an iterative visioning phase, also referred to as sprint 0, directly before starting the first sprint, those tools can be integrated to assure a complete software product definition process. That will ensure that, even in this early stage, the agile project is focused on user needs represented by “personas”.

Empirical Labor Search: A Survey This paper surveys the existing empirical research that uses search theory to empirically analyze labor supply questions in a structural framework, using data on individual labor market transitions and durations, wages, and individual characteristics. The starting points of the literature are the Mincerian earnings function, Heckman's classic selection model, and dynamic optimization theory. We develop a general framework for the labor market where the search for a job involves dynamic decision making under uncertainty. It can be specialized to be in agreement with most published research using labor search models. We discuss estimation, policy evaluation with the estimated model, equilibrium model versions, and the decomposition of wage variation into factors due to heterogeneity of various model determinants as well as search frictions themselves. We summarize the main empirical conclusions. JEL Classification: J6, J42, J41, J31, J21, D8, C4
YSOVAR : MidIR Variability in the Star Forming Region Lynds 1688

The emission from young stellar objects (YSOs) in the mid-IR is dominated by the inner rim of their circumstellar disks. We present an IR-monitoring survey of ∼ 800 objects in the direction of the Lynds 1688 (L1688) star forming region over four visibility windows spanning 1.6 years using the Spitzer space telescope in its warm mission phase. Among all lightcurves, 57 sources are cluster members identified based on their spectral-energy distribution and X-ray emission. Almost all cluster members show significant variability. The amplitude of the variability is larger in more embedded YSOs. Ten out of 57 cluster members have periodic variations in the lightcurves with periods typically between three and seven days, but even for those sources, significant variability in addition to the periodic signal can be seen. No period is stable over 1.6 years. Non-periodic lightcurves often still show a preferred timescale of variability which is longer for more embedded sources. About half of all sources exhibit redder colors in a fainter state. This is compatible with time-variable absorption towards the YSO. The other half becomes bluer when fainter. These colors can only be explained with significant changes in the structure of the inner disk. No relation between mid-IR variability and stellar effective temperature or X-ray spectrum is found.

The prevalence of diabetic retinopathy in Faisalabad, Pakistan: a population-based study

To determine the plasma prevalence and characteristics of diabetic retinopathy (DR) among Pakistani diabetic patients in the Faisalabad region. Diabetes mellitus (DM) is a major cause of avoidable blindness worldwide. People with DR are 25 times more likely to become blind than nondiabetics. Materials and methods: The incidence of retinopathy was determined in 1524 people with diabetes during April 2008 and January 2009. Physician-diagnosed diabetic patients underwent an eye examination by ophthalmoscopy and fundus photography. Participants were also interviewed and examined in order to determine demographic characteristics and medical history. Results: Of the 1524 patients screened, 183 (12%) had DR. Of these, 7% (106) had nonproliferative DR and 5% (77) had proliferative DR. Clinically significant macular edema was detected in 1.2% of patients. The prevalence of DR was higher in patients with type 1 diabetes than in those with type 2 diabetes. This difference was found to be statistically insignificant, however (P > 0.05). About 3% of the diabetic patients in our study had a family history of diabetes and only 6% had a history of regular eye examinations. Conclusion: This study demonstrated a high prevalence of DR in Faisalabad. An organized approach is needed to ensure adequate prevention and treatment in patients with diabetes.
- 1-Improving Participation and Learning with Gamification

In this paper we explore how gamification can be applied to education in order to improve student engagement. We present a study in which a college course was gamified, by including experience points, levels, badges, challenges and leaderboards. The study was five years long, where the first three were non-gamified years, and the last two regarded two successive experiments of our gamified approach. To assess how gamification impacted the learning experience, we compared data from both gamified and non-gamified years, using different performance measures. Results show significant improvements in terms of attention to reference materials, online participation and proactivity. They also suggest that our approach can reduce grade discrepancies among students and help them score better. Modeling course activities with game challenges and properly distributing those over the term seem to enhance this effect.
“ It ’ s almost like they ’ re trying to hide it " : How User-Provided Image Descriptions Have Failed to Make Twiter Accessible Cole Gleason

To make images on Twitter and other social media platforms accessible to screen reader users, image descriptions (alternative text) need to be added that describe the information contained within the image. The lack of alternative text has been an enduring accessibility problem since the “alt” attribute was added in HTML 2.0 over 20 years ago, and the rise of user-generated content has only increased the number of images shared. As of 2016, Twitter provides users the ability to turn on a feature that allows descriptions to be added to images in their tweets, presumably in an efort to combat this accessibility problem. What has remained unknown is whether simply enabling users to provide alternative text has an impact on experienced accessibility. In this paper, we present a study of 1.09 million tweets with images, fnding that only 0.1% of those tweets included descriptions. In a separate analysis of the timelines of 94 blind Twitter users, we found that these image tweets included descriptions more often. Even users with the feature turned on only write descriptions for about half of the images they tweet. To better understand why users provide alternative text descriptions (or not), we interviewed 20 Twitter users who have written image descriptions. Users did not remember to add alternative text, did not have time to add it, or did not know what to include when writing the descriptions. Our fndings indicate that simply making it possible to provide image descriptions is not enough, and reveal future directions for automated tools that may support users in writing high-quality descriptions.
Nunatak 04316 aubrite : Origin by pyroclastic volcanism

We studied the mineralogy, petrology, and bulk, trace element, oxygen, and noble gas isotopic compositions of a composite clast approximately 20 mm in diameter discovered in the Larkman Nunatak (LAR) 04316 aubrite regolith breccia. The clast consists of two lithologies: One is a quench-textured intergrowth of troilite with spottily zoned metallic Fe,Ni which forms a dendritic or cellular structure. The approximately 30 lm spacings between the Fe,Ni arms yield an estimated cooling rate of this lithology of approximately 25–30 C s. The other is a quench-textured enstatite-forsterite-diopside-glass vitrophyre lithology. The composition of the clast suggests that it formed at an exceptionally high degree of partial melting, perhaps approaching complete melting, and that the melts from which the composite clast crystallized were quenched from a temperature of approximately 1380–1400 C at a rate of approximately 25–30 C s. The association of the two lithologies in a composite clast allows, for the first time, an estimation of the cooling rate of a silicate vitrophyre in an aubrite of approximately 25–30 C s. While we cannot completely rule out an impact origin of the clast, we present what we consider is very strong evidence that this composite clast is one of the elusive pyroclasts produced during pyroclastic volcanism on the aubrite parent body (Wilson and Keil 1991). We further suggest that this clast was not ejected into space but retained on the aubrite parent body by virtue of the relatively large size of the clast of approximately 20 mm. Our modeling, taking into account the size of the clast, suggests that the aubrite parent body must have been between approximately 40 and 100 km in diameter, and that the melt from which the clast crystallized must have contained an estimated maximum range of allowed volatile mass fractions between approximately 500 and approximately 4500 ppm.
The Process of Coping with Changes : A Study of Learning Experiences for the Aboriginal Nursing Freshmen

Ruo Lan LIU National Taiwan Normal University Abstract Background: Given the increasing presence of aborigines in Taiwan higher education, especially in nursing institutes, the retention and adaptation of aboriginal students is a critical issue for research. Understanding the adjustment and transformation process of aboriginal nursing freshmen is very important for improving their learning, but very little information can be found about their experiences. Aims: In order to provide the references to improve the qualities of multi-ethnic learning in the future, this study is to explore and gain a deeper understanding of the adjustment process of aboriginal nursing freshmen and the meaning they drew from their learning. Participants: The study recruited 20 female aboriginal freshmen from the five year nursing program. These students came from different areas or tribes in Taiwan. The age for these students was from 15 to 17. Methods: A qualitative method was adopted to conduct this research. The primary method for data collection was a series of in-depth interviews conducted by six well-trained interviewers with backgrounds in counseling during the first year of participants’ school life. The data analysis was carried out by open coding, axial coding and determining the core theme. Conclusions: ‘Coping with changes’ was the core theme for describing and guiding the process of first year college life. During the process, the four most common challenges were: (1) Excitement and fear collide initially; (2) Confronting reality; (3) Seeking connection; (4) Getting along with all. Based on the above results, we contend that the aboriginal students need to seek connections. The aboriginal freshmen appreciate teachers who are sensitive to their culture, and they need more support for aboriginal student clubs. Curriculums and pedagogies designed for aboriginal students may benefit them in reaching their highest potential in both academic and social psychological development. This study, therefore, suggests that the institute should offer different programs for the aboriginal nursing freshmen in different adjustment stages.
Analysis on Movie Reviews using Recurrent Neural Network

In this paper i have done sentiment analysis on IMDB dataset using Recurrent Neural network. Sentiment analysis based on text mining or opinion mining based on different dataset. Sentiment classification is done in three categoriesPositive, Negative and Neutral. Text classification is done on the dataset and data preprocessing is done to remove hastags, synonms, acronyms etc. LSTM Recurrent Neural Networks to other algorithms for classifying the sentiment of movie reviews. Recurrent neural network provides high accuracy and polarity as compared to different machine learning classifiers. To address this task deep learning has become popular method. LSTM (Long short-term memory) model has been used which is a modified version of RNN (Recurrent Neural Networks). Recurrent Neural Networks has ability handle sequential data very effectively and without performing any feature engineering it can learn directly from low-level features. Instead of exploring LSTMs abilities and capabilities, main focus was to learn how embedding can help us to understand user expectations from text. Proper preprocessing for data has been implemented. Informal language, contextualization, bad grammatical structure, misspellings are additional complicating factors. Reviews are analyzed as binary classification task, after processing reviews are classified as either negative or positive. Features for training and testing the deep learning model were retrieved by using new method called ‘word-vector’. Moreover, effect of sentence length has also been investigated. Sentiment analysis for short sentences becomes difficult because of lack of contextual information. Multiple hidden layers have been used in the architecture. Dropout, Normalization and Parametric Rectified Linear Unit (PReLU) technology has been used to generalize and improve the accuracy of model. Also, the impact of various hyper-parameter has analysed. Different neural network configurations are evaluated. The performance of model is discussed with respect to the input data and model configuration.
The Changing Wage Distribution and the Decline of Marriage *

In the last forty years, the share of married adults has declined in the United States. At the same time, the structure of labor market earnings has greatly changed, both in its cross-sectional distribution and in terms of life-cycle dynamics. In this paper, I estimate a novel equilibrium model of the marriage market characterized by search frictions, endogenous divorce, aging, and wage mobility. This structural approach allows me to provide a quantitative assessment of the impact of changes in the wage structure on the decline of marriage. I find that changes in the wage distribution as a whole can account for about 35% of the decline in the share of married adults between the 1970s and the 2000s, and partly explain why the decline has been stronger among the low educated. I show that changes in positional wage inequality matter far more than changes in wage mobility: increased inequality among men and a shrinking gender wage gap have caused the gains from marriage to shift from household specialization to the possibility of joining efforts on the labor market.
Rapid quanti fi cation of the adulteration of fresh coconut water by dilution and sugars using Raman spectroscopy and chemometrics

Here, for the first time, we developed Raman spectroscopy in combination with chemometrics for the quantification of adulteration of fresh coconut water by dilution, and its masking with sugars. Coconut water was extracted from young Costa Rican coconuts and heat treated to emulate pasteurization. Samples were then adulterated by dilution with water and single sugars, mixtures of sugars, and high-fructose corn syrup (HFCS). A total of 155 samples were analysed with Raman spectroscopy at 785 nm excitation and 620 spectra analysed with chemometrics. Results showed successful quantification of dilution and adulteration with single sugars between 1.9 and 2.6%, masking of dilution with mixtures of sugars at 9.8%, and masking of dilution with HFCS at 7.1%. It can be concluded that Raman spectroscopy has significant potential as a rapid accurate analytical method for the detection of adulteration in this product, with the ability to discern small abnormalities in sugar ratios within coconut water.
