A Company

The failure of most startups in Indonesia is caused by team performance that is not solid and competent. Programmers are an integral profession in a startup team. The development of social media can be used as a strategic tool for recruiting the best programmer candidates in a company. This strategic tool is in the form of an automatic classification system of social media posting from prospective programmers. The classification results are expected to be able to predict the performance patterns of each candidate with a predicate of good or bad performance. The classification method with the best accuracy needs to be chosen in order to get an effective strategic tool so that a comparison of several methods is needed. This study compares classification methods including the Support Vector Machines (SVM) algorithm, Random Forest (RF) and Stochastic Gradient Descent (SGD). The classification results show the percentage of accuracy with k = 10 cross validation for the SVM algorithm reaches 81.3%, RF at 74.4%, and SGD at 80.1% so that the SVM method is chosen as a model of programmer performance classification on social media activities.

AbstractObjectives:Social cognitive deficits have been discussed to be endophenotypes for schizophrenia and other serious mental illnesses. The current study aimed to assess emotional intelligence (EI) in unaffected siblings of schizophrenia patients to investigate its potential role as endophenotype for schizophrenia.Methods:EI was measured in 56 schizophrenia patients, 57 unaffected siblings, and 127 healthy control subjects by using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). In addition, non-social cognition was assessed with the Brief Assessment of Cognition in Schizophrenia (BACS). Linear mixed models with compound symmetric correlation structure were used for of the three groups with respect to EI and non-social cognition.Results:Schizophrenia patients showed significantly lower overall EI and performed significantly worse in three out of four MSCEIT branches compared to unaffected siblings and control subjects, whereas the two latter groups had comparable EI levels. Similar performance patterns (patients<unaffected siblings=control subjects) were found with respect to non-social cognition. Solely in the “Tower of London” test, siblings achieved significantly lower task scores compared to control subjects.Conclusions:Based on our results, EI as measured with the MSCEIT does not seem to represent a marker of risk for schizophrenia. Further investigations should concentrate on other EI measures to reassess this finding. (JINS, 2017,23, 577–583)

Separate Room

Students with attention-deficit/hyperactivity disorder (ADHD) are frequently provided a separate room in which to take exams, to reduce external distractions. However, little research has explored the efficacy of this accommodation. In the present study, college students with ( n = 27) and without ( n = 42) ADHD diagnoses were administered two parallel forms of a timed silent reading comprehension test, one in a classroom with other students, and one in a private, proctored setting. A two-way analysis of variance found no significant main effects for either ADHD status or test setting on performance, and no significant interaction between the factors either. However, inspection of student-level data and exploration of continuous relationships between self-reported ADHD symptoms and test performance patterns suggested that separate room accommodations may be beneficial for a subgroup of students with ADHD.
