Amobee at IEST 2018: Transfer Learning from Language Models
This paper describes the system developed at Amobee for the WASSA 2018
implicit emotions shared task (IEST). The goal of this task was to predict the
emotion expressed by missing words in tweets without an explicit mention of
those words. We developed an ensemble system consisting of language models
together with LSTM-based networks containing a CNN attention mechanism. Our
approach represents a novel use of language models (specifically trained on a
large Twitter dataset) to predict and classify emotions. Our system reached 1st
place with a macro score of 0.7145.Comment: 7 pages, accepted to the 9th WASSA Workshop, part of the EMNLP 2018

ArbDialectID at MADAR Shared Task 1: Language Modelling and Ensemble Learning for Fine Grained Arabic Dialect Identification
In this paper, we present a Dialect Identification system (ArbDialectID) that competed at Task 1 of the MADAR shared task, MADARTravel Domain Dialect Identification. We build a course and a fine-grained identification model to predict the label (corresponding to a dialect of Arabic) of a given text. We build two language models by extracting features at two levels (words and characters). We firstly build a coarse identification model to classify each sentence into one out of six dialects, then use this label as a feature for the fine-grained model that classifies the sentence among 26 dialects from different Arab cities, after that we apply ensemble voting classifier on both sub-systems. Our system ranked 1st that achieving an f-score of 67.32%. Both the models and our feature engineering tools are made available to the research community.In this paper, we present a Dialect Identification system (ArbDialectID) that competed at Task 1 of the MADAR shared task, MADARTravel Domain Dialect Identification.

Highlight on the problems generated by p-coumaric acid analysis in fermentations
p-Coumaric acid is a natural hydroxycinnamic acid existing in grapes and wine. It is the precursor of the 4-ethylphenol molecule through the bioconversion reaction by Brettanomyces yeast. Chromatographic methods are the most common techniques to detect p-coumaric acid. It is known that this acid is highly unstable in analysis and fermentation experiments. This paper highlights the problems occurring in p-coumaric acid analysis in wine fermentation conditions when studying its bioconversion. First, it was shown that p-coumaric acid was unstable at elevated temperature. On the other hand, it was found that in our experimental conditions p-coumaric acid reacted with ethanol. This work revealed also that the p-coumaric acid is partially adsorbed on Brettanomyces yeast, certainly on cell walls. Because of these phenomena the quantity of p-coumaric acid which can participate to the bioconversion into ethylphenol decreases
Health Risk Perceptions, Awareness and Handling Behaviour of Pesticides by Farm Workers
The level of awareness regarding pesticide use/ handling has been reported in the farms of Kerala and the same has been compared with the adoption pattern and experiences of health risk episodes, in a society with high level of literacy. The understanding on various aspects of pesticide-use has revealed better awareness in certain aspects and poor understanding in certain others. The workers have not been given adequate training to understand the toxicity level by looking at the colour code on the packet, though they have been found aware about the different options available in the market. Often their perceptions of toxicity level of chemicals they handle are not in conformity with the actual situation; they have been found handling toxic chemicals considering them to be safe ones. Despite a high literacy level, most of them do not care to read the instructions and follow them. The study has found that a majority of the respondents are of satisfactory health status by the body mass index values. The short-term health risk upon occupational exposure has been reported very common; its frequency increases as one gets more years of experience in the work. It has been attributed to their inadequate understanding of the toxicity levels, unscientific handling practices and poor personal protective mechanism. The study has highlighted the need for targeted trainings to farm labourers besides farmers on the scientific management of pesticides and undertaking of massive awareness generation programmes.Agricultural and Food Policy,
A review of trade liberalisation and trade between Jordan and the United States
Promoting trade is a key aspect of Jordanâs development policy. As a developing country, increasing exports and maintaining a healthy balance of trade with its trading partners are amongst the governmentâs most important goals. The Free Trade Agreement (FTA) signed with the United States in 2000 is a cornerstone of Jordanâs foreign economic policy and a key test case for its broader policy of trade liberalisation. Yet while there is some evidence for a positive relationship between trade liberalisation, and increased bilateral trade and economic growth, this approach to development is also criticised for opening up developing markets to competition from their more advanced counterparts. This investigation argues that FTAs do facilitate bilateral trade but that states with large and advanced economies benefit more than small developing states and markets. To explore this argument, this study examines overall levels of bilateral trade between Jordan and the United States before and after the JUSFTA came into effect. Linear trendline projections are used to offer a comparison between experienced levels of trade and projected potential levels of trade based on pre-JUSFTA era data
Physical Environmental Quality and Urban Design Education in Palestine and Turkey
Urban designers fail to design high quality environments either because of economical constraints or educational limitation. This study aims to compare physical environmental quality and education system in two countries, Palestine and Turkey. The quantity of design education departments in each country, the course contents in each department, the quantity and profession of instructors in each department, presence of a course related to environment and behaviour studies or design theories were compared. What needs to be improved in design education to create better environments is discussed as well as the directions for future studies.Š 2016. The Authors.
