Personality Mining System for Automated Applicant Ranking

Abstract. In the last decades the explosion of ICT has opened up new avenues regarding peoples' accessibility to new job opportunities. Current technological advances in conjunction with people's online presence provide a great opportunity to automate the recruitment process and make it more effective. In this paper, we propose a novel approach for improving the efficiency of erecruitment systems. Our approach relies on the linguistic analysis of data available for job applicants, in order to infer the applicants' personality traits and rank them accordingly. To showcase the functionality of our method, we employed it in a web based e-recruitment system that we implemented

SiO2 Applications as an Alternative to Insect Control in Greenhouses

Silicon dioxide (SiO2) has been extensively studied as an alternative method to pest management chemical applications in agriculture. The present work aimed to evaluate the insecticidal efficacy of different SiO2 nanoparticle formulations and their effectiveness when integrated into the textiles of an insect-proof net. For this reason, Sitophilus oryzae and Tribolium confusum were exposed to three inert dust formulations, namely Sylobloc® S200, S200-OH, and S200MEC, to investigate their effect on the mortality of the aforementioned stored-product insects. The results of a series of bioassays showed that Sylobloc® S200 was the most effective nanoparticle among all the formulations tested. Thus, five samples of the same 50 mesh size insect-proof net were coated with the S200 nanoparticle, followed either by different coating repetitions or by the addition of paraffin. T. confusum was indicated as the most tolerant species, as the recorded mortality rate was significantly low when exposed to all samples tested. However, the mortality rate of S. oryzae was strongly related to the coating repetition, in addition to the exposure intervals. The highest mortality (70%) was detected after seven days of exposure to the net and consisted of three coating repetitions, while no paraffin was added to its surface. The results of the present study underline the insecticidal efficacy of SiO2 treated nets against storage insects, and their subsequent application in greenhouses for the control of more susceptible insects

Effect of NaCl or Macronutrient-Imposed Salinity on Basil Crop Yield and Water Use Efficiency

Cascade hydroponics, that is, the application of the circular economy concept in greenhouse hydroponic crops, may be considered as an alternative means to increase water and nutrient use efficiency in greenhouses. In such systems, the drained nutrient solution from a crop may be used as input in a second crop. However, the second (secondary) crop in the loop must be a crop that is less sensitive to salinity than the first (primary) crop. In the present study, the salinity tolerance of basil plants grown in rockwool and nutrient film technique (NFT) systems was investigated in order to study the potential of using a basil crop as a secondary crop in a cascade hydroponic system. In total, 4 electrical conductivity (EC) levels of the irrigation nutrient solution were tested (2, 4, 6, and 8 dS m−1), and salinity was imposed by NaCl or by macronutrients. Plant growth varied across the different substrates, with those grown in the NFT system being less affected as opposed to the rockwool-grown basil plants, which showed a significant growth decrease with EC values higher than 4 dS m−1. This relatively low growth pattern was associated with a decrease in water use efficiency (WUE) in the rockwool system. On the contrary, in the NFT system, the continuous flow of the nutrient solution in the root zone of the plants contributed to the alleviation of negative salinity effects, yielding up to 30 kg FM m−2 WUE even for the plants irrigated with the highest salinity treatment (8 dS m−1). The majority of macro- and micronutrients in the leaf tissue of basil were positively affected by the higher levels of conductivity in the nutrient solution. Therefore, basil cultivation could be efficiently incorporated as a secondary crop in a cascade NFT cropping system. This would contribute to drainage management in hydroponics, as the crop could be irrigated through the moderately saline drainage from a primary crop due to either NaCl or high nutrient accumulation in the leachates

Farmers concerns in relation to organic livestock production

The study describes organic producers' perceptions of organic livestock production, product commercialisation, use of contentious inputs such as allopathic antibiotics, antiparasitics and vitamins and bedding materials availability in Mediterranean (MED) and North/Western European (NWE) countries. A total of 426 MED (46.2%) and NWE (53.8%) responses were analysed revealing more difficulty finding information on alternatives to antiparasitics and antibiotics than on bedding materials. They identified 'feeding/nutrition', 'animal health' and 'welfare' as the most relevant topics in their farms. Whereas ruminants and monogastrics farmers in the NWE region also indicated 'organic regulation' as relevant, farmers rearing ruminant species in the MED region identified farm profitability and commercialisation. Farmers still mainly relied in conventional treatments but they often applied phytotherapy, although >61% of the participants did not treat their animals in the last year. If treated, most of them administered on average one course of antibiotic treatment per animal (>62%). In the MED region, the main sources of information on alternative treatments were veterinarians (>60%) and the Internet (>32%). In the NWE region, it was other farmers for producers including ruminant species (>63%) and veterinarians (>77%) for monogastric farmers. In the NWE region, direct commercialisation and through a cooperative and/or food industry were the most frequent channel used; while, in the MED region, they were the food industry and/or direct commercialisation. In conclusion, this survey provides novel cross-European insights into organic livestock producers' concerns. A particular value of the survey is that MED countries, which are often underrepresented, were well sampled.
