Soybean Peroxidase‐Catalyzed Treatment of Azo Dyes with or without Fe° Pretreatment
Authors: Cordova Villegas Laura G. , Mazloum Samar , Taylor Keith E. , Biswas Nihar 
Published: May 2018

ABSTRACT: Representative azo dyes (Acid Blue 113 [AB113] and Direct Black 38 [DB38]) were treated in a single step with soybean peroxidase (SBP) and hydrogen peroxide (H2O2), or in two steps, zero‐valent iron (Fe°) pretreatment followed SBP/H2O2. The purpose of this research was to compare both treatment processes and to determine which one was the optimal for degradation of each azo dye. For AB113, the preferred process was the single‐step process, 1.0 mM AB113 required 2.5 mM H2O2, 1.5 U/mL SBP at pH 4.0 for ≥ 95% color and dye removal and 30% total organic carbon (TOC) removal. For DB38, due to the products formed after Fe° reduction, which are enzyme substrates (aniline and benzidine; two of four products) a two‐step process was preferred, which allowed reduction in the required SBP and H2O2 concentrations by 5‐ and 2‐fold, respectively, compared to a single‐step treatment for ≥ 95% color, dye, and aniline/benzidine removal and 88% TOC removal.

ABSTRACT: This study aimed to investigate the treatment efficiency of a synthetic dye solution in an anaerobic‐aerobic combined reactor system, using pretreated residual yeast as a nutrient source and redox mediator. The applicability of the residual yeast as a nutrient source was firstly evaluated in anaerobic batch tests. Subsequently, two continuous bench‐scale treatment settings were studied: (1) an Upflow Anaerobic Sludge Blanket (UASB) reactor followed by an activated sludge system and, (2) a UASB reactor followed by a shallow polishing pond. The two system configurations were fed with a synthetic azo dye solution of Yellow Gold Remazol (50 mg/L) and pretreated residual yeast (350 mg/L). According to the results, the UASB/shallow polishing pond‐combined reactor attained the best values of chemical oxygen demand (COD) (85%) and dye removal (23%).
Emotion Recognition Using Smart Watch Sensor Data: Mixed-Design Study
Authors: Quiroz Juan Carlos , Geangu Elena , Yong Min Hooi 
Published: May 2018

Background
Research in psychology has shown that the way a person walks reflects that person’s current mood (or emotional state). Recent studies have used mobile phones to detect emotional states from movement data.

Objective
The objective of our study was to investigate the use of movement sensor data from a smart watch to infer an individual’s emotional state. We present our findings of a user study with 50 participants.

Methods
The experimental design is a mixed-design study: within-subjects (emotions: happy, sad, and neutral) and between-subjects (stimulus type: audiovisual “movie clips” and audio “music clips”). Each participant experienced both emotions in a single stimulus type. All participants walked 250 m while wearing a smart watch on one wrist and a heart rate monitor strap on the chest. They also had to answer a short questionnaire (20 items; Positive Affect and Negative Affect Schedule, PANAS) before and after experiencing each emotion. The data obtained from the heart rate monitor served as supplementary information to our data. We performed time series analysis on data from the smart watch and a t test on questionnaire items to measure the change in emotional state. Heart rate data was analyzed using one-way analysis of variance. We extracted features from the time series using sliding windows and used features to train and validate classifiers that determined an individual’s emotion.

Results
Overall, 50 young adults participated in our study; of them, 49 were included for the affective PANAS questionnaire and 44 for the feature extraction and building of personal models. Participants reported feeling less negative affect after watching sad videos or after listening to sad music, P<.006. For the task of emotion recognition using classifiers, our results showed that personal models outperformed personal baselines and achieved median accuracies higher than 78% for all conditions of the design study for binary classification of happiness versus sadness.

Conclusions
Our findings show that we are able to detect changes in the emotional state as well as in behavioral responses with data obtained from the smartwatch. Together with high accuracies achieved across all users for classification of happy versus sad emotional states, this is further evidence for the hypothesis that movement sensor data can be used for emotion recognition.

Authors: Okeowo Florence Oluremi , Aregbeshola Rafiu Adewale 
Published: May 2018

Nigeria textile industry is characterized by questionable incentives, political uncertainty, acute power shortage, poor infrastructure, smuggling and red-tape bureaucracy, among others. The study modified the endogenous growth model within a time series (1986 and 2015) estimation techniques of Autoregressive Distributed Lagged model (ARDL). Findings revealed that the effect of simple tariff rate on textile industry is negative and statistically significant in the long-run; while trade liberalization policy measure through simple tariff rate has a lag effect before it can be effective in the textile industry. In both short and long run, real effective exchange rate depreciation worsens the performance of the textile industry in Nigeria. In the long run, a 1.0% rise in trade openness would decrease the level of textile industry performance by about 17.49%, while factor affecting textile industry performance in the short run are simple tariff rate, financial development, exchange rate changes, trade openness and labor and capital inputs respectively. The study concluded that Trade liberalization has a lag effect on textile industry performance and a significant effect on the performance of the Nigerian textile industry. It is therefore recommended that government should make concerted efforts toward providing a favorable business environment, reducing inflation and improve the infrastructural facilities for the textile industry to strive.

Published: May 2018

Managerial competencies of restaurant managers play a major role in motivating employees to be productive and to provide excellent service which, in turn, will lead to customer satisfaction. Drawing upon generational differences in work ethics and values, the authors examine the importance of managerial competencies in three age cohorts. A quantitative research design was selected using a structured questionnaire consisting of five competency domains. Data were collected from 180 restaurant managers and employees in restaurants in the City of Tshwane. The results of the Fisher exact test indicated that the importance of managerial competencies differed significantly in the three age groups. Significant differences existed for three leadership domains, two management domains, one interpersonal and one intrapersonal domain. No significant differences were recorded for the perceptions of the different age groups regarding the importance of the technical domain. For the younger generation, the ability to grant employees the opportunity to grow was regarded as highly important by all respondents. The ability to maintain discipline in the workforce was perceived as less important by the youngest age group when it was compared to the other age groups. The youngest employees felt that the ability to be innovative was not as important unlike the perception of the older age groups. The findings of this study could lead restaurant managers to a better understanding of the different generational groups, how to motivate them thereby ensuring job satisfaction and service quality.

Published: May 2018

This study investigates the impact of financial literacy, level of education in a household and gender differences on time preferences of students at a university in South Africa. The study relies on a convenient sample of (N=85, female=48%) pursuing a financial literacy course. The study uses a questionnaire, a financial literacy test and a simple binary choice experimental game that elicited individual time discount rate to gather data. Ten percent of the participants were paid (in South African rands) for their time preference choices by way of quota random sampling. Female university students’ individual time discount rate was found to be on average higher than that of their male counterparts, indicating that female university students are generally impatient, especially those with low levels of financial literacy. Our results (using a Negative Binomial Regression analysis and Ordinary Least Squares regression analysis) show that time preferences of university students aresignificantly influenced by highest level of education in the household. The OLS regression model shows that financial literacy, measured using financial literacy test, significantly influence time preferences for all subjects. The study concluded that patience levels among male university students increase as financial literacy increases. Gender, income, age and family size significantly influence time preferences of university students. Highest level of education in a household, financial literacy and gender differences have a bearing on individual time preferences.

Published: May 2018

This theoretical paper was undertaken to ascertain the causes of poor service delivery and to establish if outsourcing of public service delivery could be used to improve local Authority services. It interrogated and critiqued documents on what other researchers in their different contexts had established in view of the feasibility of outsourcing as a strategy to improve service delivery. It emerged in this study that political interference, lack of citizen participation. lack of funds and corruption were the main causes of poor service delivery in local authorities. Therefore, outsourcing was seen to bring quality and affordable services for the public while costs savings and emergence of hidden costs were the financial implications unveiled for the local authorities (LAs). Social costs, accountability for public service delivery and quality shading were cited to be the outsourcing challenges. It also emerged in this study that outsourcing can increase service quality and provide affordable services for the public. Taking into account the information that was accumulated and examined, the researchers came to the conclusion that the current services being offered by local authorities are very poor and this is attributed to many causes such as political interference, lack of citizen participation, lack of funds and corruption. The study therefore, concludes that outsourcing could be a feasible option to use to improve service delivery by local authorities.

Ikäihmisten kokemukset terveydenhuollon sähköisten palvelujen käytöstä ja kokemusten hyödyntäminen palvelujen kehittämisessä – kuvaileva kirjallisuuskatsaus
Authors: Rosenlund Milla , Kinnunen Ulla-Mari 
Published: May 2018

Lähivuosien sosiaali- ja terveydenhuollon palvelujen sähköistämisen yhtenä tarkoituksena on tukea kansalaisen aktiivisempaa otetta oman hyvinvointinsa ylläpitämiseksi ja edistämiseksi. Uudet teknologiat ja palvelujen sähköistäminen voivat kuitenkin aiheuttaa eriarvoistumista väestöryhmien välillä, sillä esimerkiksi ikääntyneiden valmiudet sähköisten palvelujen käyttöön ovat muita ryhmiä matalampia.
Ikäihmisten osuus väestörakenteesta kasvaa lähitulevaisuudessa voimakkaasti suurten ikäluokkien eläköitymisen, kuolleisuuden alenemisen sekä toisaalta lasten ja työikäisten osuuden vähenemisen seurauksena. Tämän vuoksi vanhimmista ikäluokista tulee entistä merkittävämpi sosiaali- ja terveydenhuollon käyttäjäryhmä. Sosiaali- ja terveydenhuollon palvelujen sähköistäminen vaikuttaa lähivuosina voimakkaasti sosiaali- ja terveydenhuollon palvelujen järjestämiseen. Tämän artikkelin tarkoituksena on kuvailevan kirjallisuuskatsauksen menetelmin kuvata, minkälaisia kokemuksia ikäihmisillä on terveydenhuollon sähköisten palvelujen käytöstä ja mitkä tekijät vaikuttavat terveydenhuollon sähköisten palvelujen käyttöön. Lisäksi katsauksessa kartoitetaan ikäihmisten sähköisten palvelujen käytössä kokemia ongelmakohtia, joita tulisi huomioida ikäihmisille suunnattujen palvelujen järjestelmäkehityksessä alusta alkaen.
Katsaukseen valikoituneiden artikkeleiden (n=36) perusteella havaittiin, että ikäihmisten kokemukset terveydenhuollon sähköisten palvelujen käytöstä ovat pääasiallisesti myönteisiä. Käyttöön vaikuttavat monet tekijät, joiden vaikutus on usein yksilöllinen. Joitakin yleisiä olettamia tekijöiden vaikutuksesta voidaan kuitenkin löytää. Havaitut ongelmakohdat liittyvät usein järjestelmien, sovellusten ja apuvälineiden käytettävyyteen. Yleisesti ongelmia aiheuttavat hahmottamiseen liittyvät seikat kuten sivustojen ja sovellusten ulkoasu, liian pienet fontit tai painikkeet sekä hankala navigointirakenne. Lisäksi tutkimuksessa havaittiin tietoturvaan liittyviä huolia sekä käyttäjän kokemaa leimautumisen tunnetta.
