Published: April 2019

The main objective of the current study was to enhance the solubility and dissolution of poorly water soluble drug Loratadine (LOR) through formulation of solid dispersion systems (SDs) using hydrophilic polymers. SDs were prepared by kneading method using different drug-to-polymer ratios (1:3 and 1:5) with poloxomer 188 (samples DS1, DS2) and poloxomer 407 (samples DS3, DS4) as hydrophilic polymers. In vitro drug release studies were performed on prepared SDs (DS1-DS4) and compared to pure drug (LOR only, sample DS0). Prepared SDs showed significant improvement in the release profile compared to LOR.

Authors: Grigorieva E A , Khristoforova N K
Published: April 2019

Aims: To identify regional and seasonal patterns of climate at the continental part of the Far East and to study associations between climate discomfort and population health. Methods: Correlation coefficients between climatic indices in January and July and all-cause-, cardiovascular- and respiratory mortality and morbidity were calculated. Results: The overall morbidity was similar to the national average. It was slightly lower for circulatory diseases, but higher for respiratory diseases. In some regions the latter was significantly higher than the national average. Circulatory- and respiratory morbidity was almost twice as high in Chukotka (Far North East) than in the Jewish Autonomous Region (South Far East). At the same time, the low all-cause mortality in Chukotka needs further research. Conclusions: Common and specific patterns of spatial and seasonal variations and their associations with morbidity were observed in the continental part of the Russian Far East. Wet Kata Cooling Power index by Hill seems to be the best indicator of thermal discomfort. Significant correlations between health indicators and thermal discomfort expressed by bioclimatic indices are in line with other studies suggesting links between population health in the Russian Far East and climate. Low all-cause mortality in Chukotka requires further research.

THE EFFECT OF ANIMATED PLAY PROGRAM ON IRREGULAR POSTURE FORMATION IN PRESCHOOL CHILDREN
Authors: Daniusevičiūtė Brazaitė Laura , Grėbliauskienė Brigita
Published: April 2019

Background. Insufficient back muscle tone of 6–7-year-old children does not guarantee stable spin curves. The preschool children’s posture is an important society problem that raises the scientists interest (Okely, Trost, Steele, Cliff, & Mickle, 2009), when posture is formed during the pre-school period and taking into account fine motor skills peculiarities, it is possible to ensure the optimal movement function (Rodger & Vishram, 2010). The purpose of this study was to identify the need for animated play programs and risk factors for the development of about 4–7-year-old children’s abnormal posture.

Methods. We analysed annual preventive health collaborating with public health professionals and pre-school medical personnel. Two social surveys were conducted using an anonymous online questionnaire for respondents. The first survey included questions to parents/caregivers (interpersonal level) in order to establish the psychomotor development of children up to one year of age and possible causes of abnormal posture formation. The second survey had questions to the kindergarten educators and administration (organizational level) in order to find out the need for animated play programs in the educational process. The survey questions were based on the child’s motor development principles. Research participants were 311 parents/caregivers and 117 kindergarten educators. Anonymous online surveys were conducted between October and December of 2018.

Results. According to the analysis of annual preventive health indicators, less than half of the pre-school age children were healthy in Kaunas city and with the age the number of healthy children decreased. Analysis of preventive health checks in pre-school children showed that skeletal muscle disorders were most common in children aged 4 to 6 years. Parents/caregivers, kindergarten educators and the administration indicated that physical activity had a positive effect on the child’s posture in the educational institution, but parents/caregivers had doubts that kindergarten had a favourable environment for the child’s posture correction.

Conclusion. As a result, most kindergarten educators and administrators as well as parents/caregivers believed that animated play programs in kindergarten would help to improve posture.
EFFECT OF DIFFERENT OCCLUSION PRESSURE ON PECULIARITIES OF MUSCLE BLOOD FLOW
Authors: Bunevičius Kęstutis , Grunovas Albinas , Poderys Jonas
Published: April 2019

Background. Occlusion pressure intensity influences the blood flow intensity. Immediately after the cuff
pressure is released, reactive hyperaemia occurs. Increased blood flow and nutritive delivery are critical for an
anabolic stimulus, such as insulin. The aim of study was to find which occlusion pressure was optimal to increase the
highest level of post occlusion reactive hyperaemia.
Methods. Participants were randomly assigned into one of the four conditions (n = 12 per group): control group
without blood flow restriction, experimental groups with 120; 200 or 300 mmHg occlusion pressure. We used venous
occlusion plethysmography and arterial blood pressure measurements.
Results. After the onset of 120 and 200 mm Hg pressure occlusion, the blood flow intensity significantly
decreased. Occlusion induced hyperaemia increased arterial blood flow intensity 134 ± 11.2% (p < .05) in the group
with 120 mmHg, in the group with 200 mmHg it increased 267 ± 10.5% (p < .05), in the group with 300 mmHg it
increased 233 ± 10.9% (p < .05). Applied 300 mmHg occlusion from the 12 minute diastolic and systolic arterial
blood pressure decreased statistically significantly.
Conclusions. Occlusion manoeuvre impacted the vascular vasodilatation, but the peak blood flow registered
after occlusion did not relate to applied occlusion pressure. The pressure of 200 mmHg is optimal to impact the
high level of vasodilatation. Longer than 12 min 300 mmHg could not be recommended due to the steep decrease of
systolic and diastolic blood pressures.

Published: April 2019

Background. The main aim of our research was to determine if there was a relationship between prefrontal
cortex activity during Stroop test (dependent variables) and variables of “Go/NoGo”, Balloon Analogue Risk Task,
impulsivity score, different tests of cognitive functions, moral decisions tests (altruistic or egoistic), Fitts-like motor
control task, five character traits, emotional intelligence, mood, sleepiness and perceived stress, total physical activity
of subjects (independent variables).
Methods.In total, 20 undergraduate students (mean age were 21.3, SD = 1) met the criteria and agreed to
participate in this study.
Results. Our research has shown that different brain functional outcomes, that is speed-accuracy motor control,
inhibition response control and cognitive performance, risky-taking behaviour and impulsivity control, management
of emotion, personality consciousness and physical activity have a common correlation with the increase in prefrontal
cortex activity (measured by fNIRS) during Stroop test.
Conclusion. Our studies have clearly shown that different brain functional outcomes, that is speed-accuracy
motor control, inhibition response control and cognitive performance, risky-taking behaviour and impulsivity
control, management of emotion, personality consciousness and physical activity have a common correlation with
the increase in prefrontal cortex activity (measured by fNIRS) during Stroop test. Considerable number of studies
are needed to understand what is the functional essence of these relationships, but currently there is an increase of
research establishing correlations between motor behaviour and cognition control.
RELATIONSHIP BETWEEN INVOLVEMENT IN LONG- TERM REGULAR PHYSICAL ACTIVITY AND MEMORY: PRELIMINARY RESULTS
Authors: Sneidere Kristine , Harlamova Jelena , Ulmane Zane , Arnis Voldemars , Vanaga Andra , Stepens Ainars
Published: April 2019

Background. Ageing of the Western Society has become both – economic and social concern. Ageing has
both – biological and psychological consequences, and, with changes in the brain due to ageing (e.g. decline in
the brain volume in frontal, parietal and temporal areas, as well as hippocampus (Colcombe et al., 2003; Erickson,
Voss, Shaurya, Basak, & Szabo, 2011)), there are changes in cognitive functioning. For the past years, research has
indicated a relationship between aerobic activity interventions and increase in episodic memory (Ruscheweyh et al.,
2011), face recognition associative memory (Hayes et al., 2015) and working memory (Erickson et al., 2011).
Methods. The aim of the study was to examine the relationship between involvement in aerobic physical
activities and memory; thus 43 seniors aged from 65 to 85 (M = 71.86, SD = 5.09, 23% male) were included in the
study. Based on their physical activity experience, participants were divided into three groups – seniors with long-
term aerobic physical activity experience (n = 16), seniors that have recently taken up aerobic physical activities
(n = 19) and seniors not involved in physical activities (n = 8).
Results. The preliminary data indicated relationship between long-term involvement in physical activities and
working memory, as well as negative relationship between sedentary lifestyle and overall cognitive abilities.
Conclusions. As this is still a work in progress, one of the limitations being the small sample, these results can
be considered only as a tendency. Another limitation is the unequal gender distribution. This study was funded by the
Latvian National Research Programme BIOMEDICINE 2014–2017.
Functional profiles of online explanatory art texts
Authors: Cunningham Kelly J.
Published: April 2019

Writing about art and the teaching of art writing are becoming important issues in the art world. Furthering our understanding of art texts can inform the practice and teaching of art writing. In an effort to expand linguistic understanding of art writing, this study examines a corpus of 180 online explanatory art museum texts from the online collections of nine US museums using a functional profiles perspective. I use cluster analysis to group the 180 texts into functional profiles based on their use of twenty-one linguistic features. The cluster analysis resulted in five clusters that are interpreted functionally: Cluster 1 (n=56), ‘descriptive information’; Cluster 2 (n=30), ‘expanded form – adding interpretation and process’; Cluster 3 (n=40), ‘contextualising’; Cluster 4 (n=8), ‘process and interpretation with agency’; and Cluster 5 (n=46), ‘narrative focus’. It is posited that this understanding of online explanatory art museum texts can inform the teaching of future museum professionals.
Incorporating text dispersion into keyword analyses
Authors: Egbert Jesse , Biber Doug
Published: April 2019

Keyword analysis has become an indispensable tool for discourse analysts, being applied to identify the words that are especially characteristic of the texts in a target discourse domain. But, surprisingly, the statistical computation of keyness makes no reference to those texts. Rather, once a corpus has been constructed, it is treated as a homogeneous whole for the computation of keyness. As a result, the keywords in such lists are relatively frequent in the corpus, but they are often not widely dispersed across the texts of that corpus and are thus not truly representative of the target discourse domain. The purpose of this study is to propose a new method for keyword analysis – text dispersion keyness – that is based on text dispersion, rather than corpus frequency. We compare the effectiveness of this measure to four other methods for computing keyness, carrying out a series of case studies to identify the keywords that are typical of online travel blogs. A variety of quantitative and qualitative analyses are carried out to compare these methods based on their content-generalisability and content-distinctiveness, demonstrating that text dispersion keyness is a superior measure for generating keyword lists.

Published: April 2019

O capim amargoso é uma importante planta daninha em áreas de cultivo de soja na região sudeste de Goiás nos últimos anos, devido ao seu difícil controle. Objetivou-se neste trabalho avaliar eficiência da aplicação de diferentes herbicidas, com ou sem roçada mecânica, para controle de D. insularis perenizada. O experimento foi conduzido no IF Goiano Campus Urutaí/GO, com capim amargoso cultivado em vasos de 12 L, manejado de duas formas até a aplicação dos tratamentos: capim não roçado, com 130 dias após o transplantio, e capim roçado aos 90 dias após o transplantio, com aplicação dos herbicidas após 40 dias, na rebrota. Os tratamentos com herbicidas foram: Glyphosate 1.440 g e.a. ha-1, Cletodim 108 g i.a. ha-1, Haloxifop-p-methyl 62,35 g. i.a. ha-1 e mais uma testemunha sem aplicação de herbicidas. Foram realizadas avaliações visuais de controle em cinco épocas até os 42 dias após a aplicação dos herbicidas (DAA), sendo coletada a parte aérea das plantas aos 42 DAA para determinação da matéria seca. Os dados foram submetidos à análise de variância e teste LSD de Fisher para comparação entre as médias, a 5% de probabilidade. Os herbicidas não proporcionaram controle das plantas não roçadas, com fitointoxicação abaixo de 7,6%. O manejo de roçada seguido pela aplicação dos herbicidas proporcionou controle significativo do capim amargoso, com fitointoxicação de 82%, 59% e 64% para os herbicidas Glyphosate, Cletodim e Haloxyfop-p-methyl, respectivamente, mas sem provocar a morte das plantas, se mostrando como alternativa viável a integração do método do controle mecânico seguido pelo controle químico para aumento da eficácia no manejo de capim amargoso em áreas com alto índice de infestação.

Corruption is against the law and abuse of authority for the sake of self-enrichment, a group of people or corporations. Transparency International institutions 2015 and 2016 have placed Indonesia as one of the most corrupt countries in the world. Corruption in Indonesia has a very bad impact on various dimensions of society and nation life and can damage the economic system, democracy, politics, law, government and others. Although corruption is already so great, efforts to combat corruption have not shown optimal results. Seeing the difficulties of eradicating corruption, there needs to be a more serious and radical effort in the future to combat corruption in Indonesia, among others through: reforming political institutions, reforming the bureaucracy, formulating and implementing political ethical standards, enforcement that can give deterrent effect to corruptors , And the proper handling of corruption complaints procedures by the public.
KPFM work function characterization of ongoing reduction and oxidation of transition metal oxide crystals on examples of SrTiO3 and TiO nanowires
Authors: Wrana Dominik , Cieślik Karol , Bełza Wojciech , Rodenbücher Christian , Szot Krzysztof , Krok Franciszek
Published: April 2019

Controlling the work function of transition metal oxides is of key importance towards future energy production and storage. As majority of applications comprise the use of heterostructures, the most suitable experimental technique is Kelvin Probe Force Microscopy, providing excellent energetic and lateral resolution. In this paper we demonstrate the possibility of the precise work function characterization using the example of artificially formed crystalline titanium monoxide TiO nanowires on strontium titanate SrTiO3 surfaces providing a sharp atomic interface. The measured value of 3.31(21) eV is the first experimental work function evidence for a cubic TiO phase, being additionally subjected to significant variations among different crystallographic facets. Despite the remarkable height of the formed TiO nanowires, FM-KPFM proved to be able to achieve high lateral resolution of 15 nm, which is close to the topographical limits. In this study we show also the unique possibility of obtaining conductivity and work function maps on the same area, by combining contact and non-contact atomic force microscopy. As most of real applications require ambient operating conditions, we have additionally checked the impact of air venting on the work function of the TiO/SrTiO3(100) heterostructure, proving the surface re-oxidation occurs and results in  work function increases of 0.9 eV and 0.6 eV for SrTiO3 and TiO, respectively. In addition, the influence of physisorbed species was estimated to contribute 0.4 eV and 0.2 eV to the work function of both structures. The presented method of the KPFM (and LC-AFM) employment for the work function characterization of transition metal oxides may help to understand the reduction and oxidation impact on electronic properties, which is of high importance towards the development of effective sensing and catalytic devices.

Aquaplanet Models on Eccentric Orbits: Effects of the Rotation Rate on Observables
Authors: Adams Arthur D. , Boos William R. , Wolf Eric T.
Published: April 2019

Rotation and orbital eccentricity both strongly influence planetary climate. Eccentricities can often be measured for exoplanets, but rotation rates are currently difficult or impossible to constrain. Here we examine how the combined effects of rotation and eccentricity on observed emission from ocean-rich terrestrial planets can be used to infer their rotation rates in circumstances where their eccentricities are known. We employ an Earth climate model with no land and a slab ocean, and consider two eccentricities (e = 0.3 and 0.6) and two rotation rates: a fast Earth-like period of 24 hr, and a slower pseudo-synchronous period that generalizes spin synchronization for eccentric orbits. We adopt bandpasses of the Mid-Infrared Instrument on the James Webb Space Telescope as a template for future photometry. At e = 0.3 the rotation rates can be distinguished if the planet transits near periastron, because slow rotation produces a strong day–night contrast and thus an emission minimum during periastron. However, light curves behave similarly if the planet is eclipsed near periastron, as well as for either viewing geometry at e = 0.6. Rotation rates can nevertheless be distinguished using ratios of emission in different bands, one in the water vapor window with another in a region of strong water absorption. These ratios vary over an orbit by ≲0.1 dex for Earth-like rotation, but by 0.3–0.5 dex for pseudo-synchronous rotation because of large day–night contrast in upper-tropospheric water. For planets with condensible atmospheric constituents in eccentric orbits, rotation regimes might thus be distinguished with infrared observations for a range of viewing geometries.

We present Keck/Keck Cosmic Web Imager (KCWI) integral field spectrograph observations of the complex system surrounding SMM J02399−0136 (a lensed z = 2.8 sub-mm galaxy), including an associated Lyα nebula, a dust-obscured, broad-absorption-line quasar, and neighboring galaxies. At a 3σ surface brightness contour of 1.6 × 10−17 erg s−1 cm−2 arcsec−2, the Lyα nebula extends over 17 arcsec (≳140 physical kpc) and has a total Lyα luminosity of

(uncorrected for lensing). The nebula exhibits a kinematic shear of

over 100 pkpc with lowest velocities east of SMM J02399−0136 and increasing to the southwest. We also discover a bright, Lyα emitter, separated spatially and kinematically from the nebula, at a projected separation of ≈60 kpc from the quasar. This source has no clear central counterpart in deep Hubble Space Telescope imaging, giving an intrinsic Lyα rest-frame equivalent width greater than 312 Å (5σ). We argue that this “dark cloud” is illuminated by the quasar with a UV flux that is orders of magnitude brighter than the emission along our sightline. This result confirms statistical inferences that luminous quasars at z > 2 emit UV radiation anisotropically. Future KCWI observations of other lines, e.g., Lyβ, He ii, C iv, etc, and with polarimetry will further reveal the origin of the Lyα nebula and nature of the dark cloud.
Imaging Polarimetry of the Type I Superluminous Supernova 2018hti
Authors: Lee 李見 Chien-Hsiu 修
Published: April 2019

We present time-series imaging polarimetry observations of a very nearby superluminous supernova 2018hti at z = 0.063, to probe its explosion mechanism and shed light on the energy source powering superluminous supernovae (SLSNe). We obtain linear polarimetry using the Alhambra Faint Object Spectrograph and Camera on board the 2.5 m Nordic Optical Telescope. Our observations show polarization at the ∼1.9% level before and after the supernova reached light-curve maximum. However, this level of polarization is consistent with the line-of-sight interstellar polarization; hence, the polarization from the supernovae itself was not detected at a level of >3σ. This suggests that the explosion of SN 2018hti is almost spherical, similar to previous polarimetry studies of other SLSNe.
A new white-spotted Megaselia Rondani (Diptera: Phoridae) from western North America
Authors: Brown Brian , Wong Maria , Hartop Emily
Published: April 2019

The phorid fly genus Megaselia Rondani is a large, poorly-known taxon whose species are found worldwide.

A new species of Megaselia Rondani, M.simunorum, is described from both urban and rural sites in southern California. With a large area of white colour on the posterior part of the abdominal dorsum, it closely resembles the much more common species M.sulphurizona, but M.simunorum has distinctly thicker ventral setae on the abdomen and a differently-shaped white spot.
Taxonomic status of Apostolepis barrioi Lema, 1978, with comments on the taxonomic instability of Apostolepis Cope, 1862 (Serpentes, Dipsadidae)
Authors: Entiauspe-Neto Omar Machado , de Sena Arthur , Tiutenko Arthur , Loebmann Daniel
Published: April 2019

Apostolepis is a diverse neotropical snake genus, which has been historically subjected to poor taxonomic descriptions, largely based on either a small type series or subjective diagnoses. We evaluate the case of Apostolepisbarrioi Lema, 1978 and its intricate taxonomic history, suggesting its synonymization with Apostolepisdimidiata (Jan, 1862), and providing brief commentary on the taxonomic instability that has been plaguing the genus.
Cultural studies , production et économie morale
Authors: Hesmondhalgh David , Morin Céline
Published: April 2019

Les approches issues des cultural studies ont insufflé à la recherche sur les productions médiatiques et culturelles une vigueur nouvelle et nécessaire. Cependant, il devient de plus en plus clair au fil des ans qu’elles rencontrent également de sérieuses limites. L’évaluation menée dans cet article repose sur une première partie dans laquelle nous explorons, en profitant du recul historique, la période d’opposition entre les cultural studies et l’économie politique des années 1990, en distinguant ce que nous appelons les modes théorique et populiste des cultural studies . Nous esquissons ensuite les trois « écoles » des approches cultural studies vis-à-vis de la production et de l’économie : cultural economy , production studies , et creative industries analysis . Selon nous, ces approches en cultural studies de la production et de l’industrie dans le domaine de la culture pêchent, tant dans leur mode populiste que dans leur mode théorique, par le manque d’attention portée à des problématiques fondamentales liées à la normativité dans les rapports entre la culture, les médias et l’économie. Dans les deux dernières parties, portant sur le tournant du cultural labour et le concept d’économie morale, nous suggèrerons des solutions pour une prise en compte plus explicite des problèmes de normativité, proposant ainsi une base éthique potentiellement plus rigoureuse pour l’étude de questions importantes dans le champ de la production culturelle. Nous appliquerons succinctement ce système au rapport problématique entre les biens culturels et le bien-être dans les sociétés modernes.
Les serious games , dispositifs de communication persuasive
Authors: Fourquet-Courbet Marie-Pierre , Courbet Didier
Published: April 2019

L’article s’intéresse aux serious games persuasifs qui invitent les joueurs à résoudre des « problèmes ludiques » dans le but de provoquer chez eux des changements psychosociaux et comportementaux. Pour combler un manque dans la littérature, il propose une synthèse des recherches empiriques et expérimentales sur les processus socio-cognitifs et socio-affectifs qui se développent lors des usages des SG et qui sous-tendent la modification des comportements, des attitudes, affects et cognitions. Cette synthèse théorique est articulée autour de trois grands modèles en interaction : « l’apprentissage ludique opérant », l’apprentissage social par modelage et la médiation affective par le flow. Nous ouvrons également de nouvelles pistes de recherches parmi lesquelles un quatrième modèle basé sur la communication engageante.
Topographies réticulaires
Authors: Beaude Boris , Nova Nicolas
Published: April 2019

Comprendre l’hésitation entre les représentations topographiques et les représentations topologiques de l’espace suppose de mieux concevoir l’espace. En soulignant à quel point l’espace est essentiellement relationnel et relatif, les approches positionnelles et absolues de l’espace se révèlent n’être que des points de vue particuliers, dont l’effet de réel ne peut être entretenu que par la stabilité relative des entités considérées. En prenant l’exemple des traces numériques utilisées pour produire des représentations renouvelées des pratiques urbaines, cet article propose de souligner à quel point les pratiques spatiales sont elles-mêmes essentiellement relationnelles, par quels moyens les cartes reproduisent des illusions de territoire là où il n’y a pourtant que du réseau, et quels peuvent être les enjeux de telles représentations dès lors qu’elles sont mobilisées dans l’action.
Le chargé des réseaux socio-numériques au sein des médias
Authors: Pignard-Cheynel Nathalie , Amigo Laura
Published: April 2019

À partir d’une enquête menée au sein de onze rédactions françaises, cet article vise à étudier les modalités de gestion des réseaux socionumériques (RSN) en interrogeant les personnes qui en ont la charge. L’analyse met en évidence l’existence d’un discours partagé du métier de chargé des RSN, défini par un socle commun de huit tâches dont l’opérationnalisation présente des distinctions parfois fortes. Cette tension, entre homogénéité d’un discours et hétérogénéité des pratiques, s’explique par des jeux de négociations entre trois logiques ( gatekeeping , marketing et participative) encadrant et donnant un sens à l’action. Il apparaît enfin que ces logiques sont dépendantes de la nature des médias, des stratégies mises en œuvre et des caractéristiques organisationnelles des rédactions.
Le travail sur plateforme
Authors: Flichy Patrice
Published: April 2019

Cet article cherche à montrer ce qui fait l’unité et la diversité du travail sur plateforme. Au cœur de ce système, on trouve la présence d’un algorithme pour rapprocher l’offre et la demande, pour organiser l’activité, mais aussi le développement du travail indépendant et la participation des amateurs. Derrière ces éléments communs, on trouve une grande diversité de plateformes, l’article en propose une typologie, en retraçant la genèse de ce dispositif. Il distingue les plateformes de culture et de connaissance, le crowdworking qui peut prendre deux modalités, le freelance et le travail du clic et enfin la fourniture de services à la demande avec deux modalités : plateforme-marché, plateforme-cadre. L’article décrit, pour chaque type de plateforme, le type de travail exercé, le cadrage introduit par la plateforme, ce qui distingue l’activité des indépendants et des amateurs de celle des salariés. Il montre finalement que le travail sur plateforme peut être un travail réellement choisi, un travail en plus ou un travail faute de mieux. Selon les cas, il s’agit d’un travail ouvert (continuum entre activité amateur et activité professionnelle) ou d’une zone grise entre travail indépendant et travail salarié, entre autonomie et subordination.
A Critical Thinking Model for Nursing Judgment
Authors: Kataoka-Yahiro Merle , Saylor Coleen
Published: April 2019

ABSTRACT

Increasingly, the characteristic that distinguishes a professional nurse is cognitive rather than psychomotor ability. Critical thinking is an essential component of nursing. Yet, no clear definition or conceptualization of critical thinking for nursing judgment has existed. Lack of consensus and overlapping definitions may well diminish the profession's ability to articulate this concept and facilitate its development. This article proposes the Critical Thinking Model for Nursing Judgment, which specifies five components: specific knowledge base, experience, competencies, attitudes, and standards. The model has three levels of critical thinking: basic, complex, and commitment. It provides a definition and conceptualization of critical thinking based on a review of the literature and input from nurses and nurse educators. The model provides a first step for development of further research and educational strategies to promote critical thinking as an essential part of autonomous, excellent nursing practice.
Closed Refrigerated Display Cabinets
Authors: Laguerre Onrawee , Chaomuang Nattawut
Published: April 2019

The use of closed refrigerated display cabinets in supermarkets is in progression because of the potential energy saving compared to the open ones with an air infiltration at the front. However, the influence of the presence of doors on product temperatures (determining factor of product quality) is much less studied. For better understanding the interest of the use of closed display cabinets, this chapter presents the state of the art of field studies, the airflow and temperature profile in the closed display cabinet, the influence of the presence of doors/the frequency of door openings and the room temperature. Finally, a literature review of studies on food quality in the closed display cabinet is presented.

Reference on Mycotoxins Occurrence, Prevalence, and Risk Assessment in Food Systems
Authors: Atungulu Griffiths , Mohammadi-Shad Zeinab
Published: April 2019

Mycotoxins are a group of naturally occurring toxins that are produced by different filamentous fungi genera such as Aspergillus, Penicillium, Fusarium, etc. The word mycotoxin literally is derived from Greek word “myke” meaning fungus and “toxicum” meaning toxin. These contaminants can develop on different food and feed commodities during different stages including pre-harvest, harvest, and storage. Mycotoxins are of concern because their outbreak result in animal and human diseases and economic losses. It has been estimated that global post-harvest losses are approximately at 50%. Human exposure to mycotoxins is typically through consumption of contaminated agricultural products or indirectly by consumption of animal products containing mycotoxins or their metabolites. The chapter provides the latest information on mycotoxin issues and challenges related to food and feed safety.
