Authors: Benetti Idonézia Collodel , Barros Paulo Henrique Pinheiro de , Wilhelm Fernanda Ax , Deon Ana Paula da Rosa , Roberti Junior João Paulo 
Published: February 2019

A psicomotricidade está presente em todas as etapas da vida, porém o período da infância ganha destaque, uma vez que é nesta época em que as funções psicomotoras começam a se desenvolver. O objetivo desta pesquisa, de cunho exploratório, descritivo e de abordagem qualitativa, foi verificar qual a percepção de oito professoras pré-escolares sobre psicomotricidade e educação infantil. Para tanto foi utilizado um roteiro de entrevista semiestruturada, cujos resultados foram analisados sob a óptica temático-categorial da Análise de Conteúdo de Bardin. As categorias definidas foram: percepção das professoras sobre a relação entre psicomotricidade e educação infantil, atividades psicomotoras trabalhadas e aspectos que dificultam/facilitam o trabalho na área. Os resultados apontam que as professoras consideram que existe uma forte relação entre psicomotricidade e educação infantil. Quanto às atividades psicomotoras desenvolvidas, foi possível constatar que elas tiveram dificuldades para conceituar certas funções psicomotoras, principalmente em relação à orientação espacial. Quanto aos aspectos facilitadores e dificultadores, foi possível perceber que algumas apresentaram melhor condição para desenvolver atividades psicomotoras e outras afirmaram contar com a criatividade para lidar com a falta de materiais.
Fast, Nondestructive, and Cost-Effective Methods to Detect Pesticide Residues: A Case Study of Several Repatriated Karuk Tribe Artifacts
Authors: Salmo Rosene , Palmer Peter T. , Tribe Karuk 
Published: February 2019

Abstract
This study describes the use of three different nondestructive methods to determine whether or not nine artifacts belonging to the Karuk Tribe had been treated with common inorganic and organic pesticide agents. A portable X-Ray Fluorescence analyzer was used to estimate the concentrations of arsenic, mercury, and lead at two different locations on each artifact. Black beads on a necklace were found to contain 2.1% lead and 0.23% arsenic, which can be attributed to the natural composition of the beads. Leather on a drum mallet was found to contain 0.49% lead and 0.10% arsenic, which were due to the pigments used to decorate this item. Microwave Plasma-Atomic Emission Spectrometry analysis of swab samples taken from the surfaces of an elk horn, bow, and musical drum showed nondetectable levels of arsenic and lead. Gas Chromatography/Mass Spectrometry analysis of a second set of swab samples taken from the surface of each artifact showed nondetectable levels of p-dichlorobenzene, naphthalene, dichlorodiphenyltrichloroethane, and other common organic pesticides. These results suggest that these artifacts were not treated with pesticides for preservation purposes, and hence they can be handled, worn, and used as intended.
Moving and Transforming Care of One of the Largest Southwest Archaeological Collections: The Museum of Indian Arts and Culture's Move to the Center for New Mexico Archaeology
Authors: Kieffer C.L. , Clifton Julia , Mendoza Lisa 
Published: February 2019

Abstract
After over two decades of planning and five years of conserving, packing, and moving, the Museum of Indian Arts and Culture has finished the first two phases of the largest move of archaeological artifacts in the museum's history and quite possibly in the American Southwest. Framed within the historical background of evolving collection storage over many decades, the Archaeological Research Collections were moved from the Laboratory of Anthropology and another off-site storage location to a new state of the art off-site facility at the Center for New Mexico Archaeology (CNMA). Decisions that eased the overall move, including issues resulting from the move and how they were remedied, are discussed. Overall, this particular collections move demonstrates the capabilities that a small staff can have if given enough time, volunteers, and grant resources.
Measurement of pH in Ethanol, Distilled Water, and their Mixtures: On the Assessment of pH in Ethanol-Based Natural History Wet Collections and the Detrimental Aspects of Dilution with Distilled Water
Authors: Kotrba Marion , Schilling Lars-Hendrik 
Published: February 2019

Abstract
The measurement of the pH in alcohol-preserved natural history collections is fraught with considerable theoretical and methodological difficulties. A major problem is the concentration-dependent effect of ethanol. Based on empirical results in connection with data from the literature, this study aims to estimate the shape and magnitude of this effect and suggest an approximate method to correct for it. It surfaces that considerable problems are caused by the use of distilled water for the dilution of preservation fluids.

Published: February 2019

The study assessed the performance of public sector funded infrastructure in Nigeria, with a special focus on airports. It utilized secondary data obtained from the Federal Airports Authority of Nigeria (FAAN), the Nigerian Civil Aviation Authority (NCAA), and the National Bureau of Statistics (NBS) covering the period 2004 to 2016. A simple regression analyses of the data were carried out using total number of employees as the predictor variable and the total aircraft movement, total passenger movement, and total cargo movement as the dependent variables. The results of the analyses show that the p values calculated were < 0.05 alpha value, implying existence of a statistical relationship among the dependent variables (aircraft movement, passenger throughput, and cargo throughput) and independent variable (number of employees). Furthermore, the time series graphs show fluctuations in growth of the outputs (passenger throughput, aircraft movement and cargo throughput) for the Nigerian air transport system at various periods. This study has shown that there is a need for the government and stakeholders to take immediate actions in tackling factors responsible for the decline and fluctuations in the air transport industry.
Perceived influence of relationship communication on insurance service quality and customer satisfaction
Authors: Effiong Andem Ita 
Published: February 2019

Extant literature in marketing and communications has long recognized the importance of effective communication as the essential link for sustainable relationship between organizations and their customers. In spite of its importance, many studies have revealed that practices of communication in relationship marketing in some service firms are fraught with problems, which influence the perceptions of customers about the commitment of those organizations to service quality and customer value. This exploratory study was undertaken to analyze how insurance customers perceive their relationships with insurers through received messages. The study also sought to identify the inherent differences in the perception of relational messages received from insurers by the customers based on gender. A simple random sample of 145 insurance customers were drawn for the study from three insurance agencies. Useful responses were received from 120 automobile insurance policyholders, which represented 82.76% of the sample. Four hypotheses were tested with Pearson Correlation, one-way analysis of variance (ANOVA), and multiple regression analysis. The results of the study suggested significant relationship between relational messages, service quality, and customer satisfaction. In terms of differences in the perceptions of male and female respondents, the study indicated significant differences in the perception of personal values and perceived quality through received messages. Similarly, significant differences were recorded in the perception of message credibility by the female participants as compared with those of the males. The study also revealed the need for insurance companies to fully imbibe relationship communication with their customers, through assessment of the internal and external situations which surround the information needs of individual customers.
Exploring University ESL/EFL Teachers’ Emotional Well-Being and Emotional Regulation in the United States, Japan and Austria
Authors: Talbot Kyle , Mercer Sarah 
Published: February 2019

AbstractTeacher well-being has been shown to play a central role in the quality of teaching and student achievement (Day & Gu, 2009; Klusmann, Kunter, Trautwein, Lüdtke, & Baumert, 2008). However, the teaching profession is currently in crisis as it faces record rates of burnout and attrition (Borman & Dowling, 2008; Hong, 2010; Lovewell, 2012), including stressors specific to the changing nature of foreign language teaching (Hiver & Dörnyei, 2015; Wieczorek, 2016) and to higher education (Kinman & Wray, 2013). This study seeks to understand how language teachers perceive of and experience their emotional well-being and what strategies they employ to manage it. Through a series of 12 in-depth, semi-structured interviews with ESL/EFL tertiary-level teachers in the United States, Japan and Austria, we explore a range of contexts examining how participants perceive of factors that add to or detract from their emotional well-being, the challenges and joys these teachers face in their professional and personal lives, and the most salient emotional regulation strategies that they employ to manage their emotions.
Waning and Waxing of Love: Unpacking Layers of Teacher Emotion
Authors: Li Wendy , Rawal Hima 
Published: February 2019

Abstract
In this study, we investigated how an English-as-medium-of-instruction mathematics teacher in China and an English teacher in Nepal fell into and out of love with the teaching profession. A theoretical framework of love, which drew from the theorization of love in Barcelos and Coelho (2016) and Lanas and Zembylas (2015), was adopted to provide guidance for our understanding of the construct and our interpretation of the data. In this framework, love is conceptualized as being communicated through teachers’ attending to individual students, and building a mutually supportive learning environment. In addition, love is also seen as socially and historically constructed. Our data include interviews, teaching materials, and other curricular artifacts. Our findings revealed that teachers’ love toward the profession sustains their investment in teaching, and their love of their students helps them accept the students on the latter’s own terms. In addition, a loving relationship between teachers and students was also instantiated in the mutual understanding and support between both parties during classroom interactions. Finally, we also demonstrate how our two focal teachers’ love of the profession was either enhanced or worn out due to work-related sociopolitical factors.
Kinetic Flux Vector Splitting Method for Numerical Study of Two-dimensional Ripa Model
Authors: Ahmed Sidrah 
Published: February 2019

Abstract
The kinetic flux vector splitting method has been introduced for two-dimensional system of shallow water equations with horizontal temperature gradients. The scheme preserves positivity conditions and resolves different regions of shock waves, rarefaction waves and contact discontinuity with negligible oscillations. The scheme is based on splitting of flux functions of the Ripa model. Moreover Runge-Kutta time stepping technique with MUSCL-type initial reconstruction is used to guarantee higher order accurate solution. The numerical example is taken from already published article. The obtained results reveal the accuracy and robustness of the proposed method.
A New Algorithm Based on Magic Square and a Novel Chaotic System for Image Encryption
Authors: AL-Hashemy Rageed Hussein , Mehdi Sadiq A. 
Published: February 2019

Abstract
This article introduces a simple and effective new algorithm for image encryption using a chaotic system which is based on the magic squares. This novel 3D chaotic system is invoked to generate a random key to encrypt any color image. A number of chaotic keys equal to the size of the image are generated by this chaotic system and arranged into a matrix then divided into non-overlapped submatrices. The image to be encrypted is also divided into sub-images, and each sub-image is multiplied by a magic matrix to produce another set of matrices. The XOR operation is then used on the resultant two sets of matrices to produce the encrypted image. The strength of the encryption method is tested in two folds. The first fold is the security analysis which includes key space analysis and sensitivity analysis. In the second fold, statistical analysis was performed, which includes the correlation coefficients, information entropy, the histogram, and analysis of differential attacks. Finally, the time of encryption and decryption was computed and show very good results.
Seeding the UEFA Champions League participants: evaluation of the reforms
Authors: Dagaev Dmitry , Rudyak Vladimir Yu. 
Published: February 2019

Abstract
We evaluate the sporting effects of the seeding system reforms in the Champions League, the major football club tournament organized by the Union of European Football Associations (UEFA). Before the 2015–2016 season, the teams were seeded in the group stage by their ratings. Starting from the 2015–2016 season, national champions of the Top-7 associations are seeded in the first pot, whereas other teams are seeded by their rating as before. Taking effect from the season 2018–2019, the team’s rating no longer includes 20% of the rating of the association that the team represents. Using the prediction model, we simulate the whole UEFA season and obtain numerical estimates for competitiveness changes in the UEFA tournaments caused by these seeding reforms. We report only marginal changes in tournament metrics that characterize ability of the tournament to select the best teams and competitive balance. Probability of changes in the UEFA national association ranking does not exceed several percent for any association.
Time, Leeway, and the Laws of Nature: Why Humean Compatibilists Cannot Be Eternalists
Authors: Buckareff Andrei A. 
Published: February 2019

Abstract
Humean compatibilism combines a Humean conception of laws of nature with a strong dual-ability condition for free will that requires that agents possess the ability to decide differently when they make a free decision. On the Humean view of laws of nature, laws of nature are taken to be contingent non-governing descriptions of significant regularities that obtain in the entire history of the universe. On Humean compatibilism, agents are taken to possess dual ability when making free decisions because what the laws of nature will finally be is (at least partially) dependent upon how an agent decides. In this paper, I argue that the tenability of Humean compatibilism depends in part upon what theory of time is correct. More specifically, I argue that Humean compatibilism is untenable in a deterministic universe if eternalism is true.

‘Showing one’s card’: Negotiating disclosure through game play in juvenile probation
Authors: Matarese Maureen T. , van Nijnatten Carolus 
Published: February 2019

Abstract
Communication between probation officers and juvenile offenders is essential, clarifying the nature and cause of possible disorders and providing insight into the chances of recidivism and/or recovery. Forensic social work, however, is complicated as it is both oriented toward collecting information for the court (forensic aims) and aimed at helping the juvenile’s improvement (social work aims). This paper examines two unique cases of probation officer-juvenile interaction that utilize a board game intended to foster disclosure. As any disclosure may be used against the juvenile in court, the juvenile must be compliant enough without disclosing too much. Using a combination of frame analysis and discourse analyses of delicacy, we describe how the game is used to encourage disclosure as well as how the game allows juveniles to appear compliant ultimately without disclosing much personal information.

Abstract
This study describes the adsorption of Cu (II), Co (II) and Ni (II) ions from wastewater on Vigna radiata husk biomass. The ability of adsorbent to capture the metal ions has been found to be in the order of Ni (II)>Co (II) and Cu (II) depending upon the size and nature of metal ions to be adsorbed. It has been observed that percentage removal of Cu (II), Co (II) and Ni (II) ions increases with increase of adsorbent dosage, contact time and pH of the medium but up to a certain extent. Maximum adsorption capacity (qmax) for Cu (II), Co (II) and Ni (II) ions has been found to be 11.05, 15.04 and 19.88 mg/g, respectively, under optimum conditions of adsorbent dosage, contact time and pH of the medium. Langmuir model best fits the adsorption process with R2 value approaches to unity for all metal ions as compared to other models because adsorption sites are seemed to be equivalent and only monolayer adsorption may occur as a result of binding of metal ion with a functional moiety of adsorbent. Pseudo second order kinetic model best interprets the adsorption process of Cu (II), Co (II) and Ni (II) ions. Thermodynamic parameters such as negative value of Gibbs energy (∆G°) gives information about feasibility and spontaneity of the process. Adsorption process was found to be endothermic for Cu (II) ions while exothermic for Co (II) and Ni (II) ions as signified by the value of enthalpy change (∆H°). Husk biomass was recycled three times for removal of Ni (II) from aqueous medium to investigate its recoverability and reusability. Moreover V. radiata husk biomass has a potential to extract Cu (II) and Ni (II) from electroplating wastewater to overcome the industrial waste water pollution.

Published: February 2019

OBJECTIVES:
Evidence supports using dexamethasone for mild-to-moderate asthma exacerbations in the emergency department, but the effectiveness of dexamethasone versus prednisone for asthmatic patients who are hospitalized is unclear. Our aim was to compare outcomes for inpatients before and after our emergency department’s adoption of dexamethasone for the treatment of acute asthma exacerbations.

METHODS:
In this single-center retrospective cohort study, we employed interrupted time series analyses to control for secular trends while evaluating our outcomes of length of stay, total inflation-adjusted hospital charges, and ICU transfer rates for patients admitted with asthma.

RESULTS:
Data were analyzed over 36 months (January 2014–April 2017) and included 1015 subjects (606 in the preprotocol change [pre-PC] group and 409 in the postprotocol change [post-PC] group). In the pre-PC group, prednisone only was used in 96% of subjects. In the post-PC group, prednisone only was used in 7% of subjects, dexamethasone in 65% of subjects, and a combination of the 2 steroids in 28% of subjects. Controlling for other variables in the interrupted time series model, we found no significant immediate differences between the pre-PC and post-PC periods for the outcomes of length of stay (P = .68), total charges (P = .66), and ICU transfers (P = .98). The rate of ICU transfers was stable pre-PC and increased by 10% (95% confidence interval: 2%–19%) per month (odds ratio = 1.10; 95% confidence interval: 1.02–1.19; P = .02) in the post-PC period.

CONCLUSIONS:
After dexamethasone replaced prednisone as the most commonly prescribed steroid type for inpatients with asthma at our institution, we found no immediate changes in outcomes for asthmatic patients who were hospitalized but an upward trend in ICU transfers.
