Abstract
BACKGROUND: The purpose of the study was to determine the prevalence and characterize the resistance profiles of Escherichia coli isolated from various clinical specimens by various phenotypic and genotypic methods.
MATERIALS AND METHODS: A total of 196 consecutive, nonduplicate strains of clinically significant E. coli isolated from various clinical specimens were included in the study. Identification and antimicrobial susceptibility testing was performed by using Vitek-2 system (Biomerieux, France). Phenotypic detection of extended spectrum beta-lactamase (ESBLs), Amp-C-β lactamase (Amp C), and carbapenemase production was done by various combination of disc diffusion methods, minimum inhibitory concentration determination by E-test, followed by polymerase-chain-reaction for the detection of β-lactamase-encoding genes.
RESULTS: Overall prevalence of ESBLs, Amp C, and carbapenemase production was found to be 88.3%, 42.2%, and 65.1% by the phenotypic detection methods. Our study also revealed high resistance rates against other antibiotics such as cefepime (89%), cefotaxime (95.4%), ceftazidime (85.4%), ceftriaxone (91.8%), cefpodoxime (92.7%), aztreonam (56.3%), piperacillin/tazobactam (89.2%), and ticarcillin/clavulanic acid (76.3%). The most prevalent ESBL gene was blaTEM(67.30%), and least prevalent ESBL gene was blaVEB(2.61%). In case of Amp C, blaFOXgene (21.9%) was predominant. Among the genes encoding for carbapenemases, the most common gene was blaNDM(61.7%) followed by blaVIM(30.8%), blaKPC(10.6%), blaOXA-48 (5.3%), and blaIMP(2.1%).
CONCLUSION: Our findings suggest a high rate of ESBLs, Amp C, and carbapenemase production among the E. coli isolates. A combination of both phenotypic and genotypic methods would be ideal for better characterization of resistance patterns among the E. coli isolates.

Abstract
INTRODUCTION: Subclinical inflammation markers play a significant role in hyperemesis gravidarum (HEG). Simple hematological markers such as mean platelet volume (MPV), platelet distribution width (PDW), neutrophil-to-lymphocyte ratio (NLR), red cell distribution width (RDW), plateletcrit (PCT), and platelet-to-lymphocyte ratio (PLR) have been shown to reflect inflammatory burden and disease activity in several disorders. Ketonuria is a parameter used in the diagnosis of severe HEG, but its correlation with disease severity remains controversial. The relationship of subclinical inflammation markers with degree of ketonuria has not been examined previously. In this study, we aimed to determine the diagnostic value of these subclinical inflammation markers and the relationship between these markers and grade of ketonuria in patients with HEG.
MATERIALS AND METHODS: A total of 94 pregnant women with a diagnosis of HEG and 100 gestational age-matched healthy pregnant women were enrolled in this retrospective study. MPV, PDW, NLR, PLR, PCT, and ketonuria were calculated and analyzed from complete blood cell counts and total urine analyses.
RESULTS: Lymphocyte count was significantly higher in the control group (P < 0,001); NLR and PLR values were significantly higher in the HEG group (P < 0,001). Among inflammation markers, RDW increased significantly (P = 0,008) with an increase in ketonuria in patients with HEG. A statistically significant correlation was found between white blood cell (WBC) and NLR, PLR, PCT. A moderate uphill relationship was observed between NLR and WBC and a weak uphill linear relationship was observed between WBC and PLR and between WBC and PCTCONCLUSIONS: PLR and NLR can be considered effective markers to aid in the diagnosis of HEG. No marker was found to correlate with ketonuria grade except RDW, although the relationship of the severity of ketonuria with severity of disease is controversial. RDW increases as the degree of ketonuria increases.
The Actors Involved in Innovation Processes and Collaboration – A Case Study of Eight Finnish Municipalities

Published: May 2019

This study observes the roles of the different actors involved in the processes of innovation. The theoretical framework on which this study is based deals mainly with the idea of collaborative innovation. This is a case study of eight Finnish municipalities (Hattula, Hollola, Hämeenlinna, Kuusamo, Pudasjärvi, Raahe, Rovaniemi and Salo) and their innovation processes. The research question is: how did collaboration occur between the diverse actors during the observed development processes? The main data of this article emanates from the workshops held in these eight municipalities. Four groups of actors emerge in the empirical analysis: key actors, actors within the municipal organization, actors within the municipality and actors outside the municipality. The roles of promoters, coordinators and leaders of innovation processes and municipal management were highlighted. These key actors have the opportunities to promote and organize collaboration in the innovation processes. Collaborative practices in innovation processes are seen, as an important aim and the importance of including different stakeholders is quite widely understood. However, it seems that a systematic approach towards collaboration in these processes is lacking and in some cases the instruments for collaboration might be lacking.
Semi Queer
Authors: Balay Anne 
Published: May 2019

Long-haul trucking is linked to almost every industry in America, yet somehow the working-class drivers behind big rigs remain largely hidden from public view. Gritty, inspiring, and often devastating oral histories of gay, transsexual, and minority truck drivers allow award-winning author Anne Balay to shed new light on the harsh realities of truckers' lives behind the wheel. A licensed commercial truck driver herself, Balay discovers that, for people routinely subjected to prejudice, hatred, and violence in their hometowns and in the job market, trucking can provide an opportunity for safety, welcome isolation, and a chance to be themselves--even as the low-wage work is fraught with tightening regulations, constant surveillance, danger, and exploitation. The narratives of minority and queer truckers underscore the working-class struggle to earn a living while preserving one's safety, dignity, and selfhood.
Through the voices of drivers from marginalized communities who spend eleven- to fourteen-hour days hauling America's commodities in treacherous weather and across mountain passes, Semi Queer reveals the stark differences between the trucking industry's crushing labor practices and the perseverance of its most at-risk workers.
Holocene hydrography evolution in the Alboran Sea: a multi-record and multi-proxy comparison
Authors: Català Albert , Cacho Isabel , Frigola Jaime , Pena Leopoldo D. , Lirer Fabrizio 
Published: May 2019

Abstract. A new high-resolution deglacial and Holocene sea surface temperature (SST)
reconstruction is presented for the Alboran Sea (western Mediterranean),
based on Mg∕Ca ratios measured in the planktonic foraminifera Globigerina bulloides. This new
record is evaluated by comparison with other Mg∕Ca SST records and
previously published alkenone SST reconstructions from the same region for
both the Holocene and glacial periods. In all cases there is a high degree
of coherence between the different Mg∕Ca SST records but strong
discrepancies when compared to the alkenone SST records. We argue that
these discrepancies are due to differences in the proxy response during
deglaciation which we hypothesize to reflect a resilience strategy of G. bulloides,
changing its main growth season, and consequently Mg∕Ca records a shorter
deglacial warming than alkenones. In contrast, short-term Holocene SST
variability is larger in the Mg∕Ca SST than in the alkenone SST records.
We propose that the larger Mg∕Ca SST variability is a result of spring
temperatures variability, while the smoothed alkenone SST variability
represents averaged annual temperatures. The Mg∕Ca SST record
differentiates the Holocene into three periods: (1) the warmest SST values
occurred during the Early Holocene (11.7–9 cal. kyr BP), (2) a continuous
cooling trend occurred during the Middle Holocene that culminated in the
coldest Holocene SST having a double cold peak structure centred at around
4.2 cal. kyr BP, and (3) the Late Holocene (4.2 cal. kyr BP to present) did not follow any
clear cooling/warming trend although millennial-scale oscillations were
enhanced. This SST evolution is discussed in the context of the changing
properties in the Atlantic inflow water associated with North Atlantic
circulation conditions and also with local hydrographical and atmospheric
changes. We propose that a tight link between North Atlantic circulation
patterns and the inflow of surface waters into the Mediterranean played a
major role in controlling Holocene climatic variability of this region.
Bayesian inference and predictive performance of soil respiration models in the presence of model discrepancy
Authors: Elshall Ahmed S. , Ye Ming , Niu Guo-Yue , Barron-Gafford Greg A. 
Published: May 2019

Abstract. Bayesian inference of microbial soil respiration models is often based on the
assumptions that the residuals are independent (i.e., no temporal or spatial
correlation), identically distributed (i.e., Gaussian noise), and have
constant variance (i.e., homoscedastic). In the presence of model
discrepancy, as no model is perfect, this study shows that these assumptions
are generally invalid in soil respiration modeling such that residuals have
high temporal correlation, an increasing variance with increasing magnitude
of CO2 efflux, and non-Gaussian distribution. Relaxing these three
assumptions stepwise results in eight data models. Data models are the basis
of formulating likelihood functions of Bayesian inference. This study
presents a systematic and comprehensive investigation of the impacts of data
model selection on Bayesian inference and predictive performance. We use
three mechanistic soil respiration models with different levels of model
fidelity (i.e., model discrepancy) with respect to the number of carbon pools
and the explicit representations of soil moisture controls on carbon
degradation; therefore, we have different levels of model complexity with
respect to the number of model parameters. The study shows that data models
have substantial impacts on Bayesian inference and predictive performance of
the soil respiration models such that the following points are true: (i) the
level of complexity of the best model is generally justified by the
cross-validation results for different data models; (ii) not accounting for
heteroscedasticity and autocorrelation might not necessarily result in biased
parameter estimates or predictions, but will definitely underestimate
uncertainty; (iii) using a non-Gaussian data model improves the parameter
estimates and the predictive performance; and (iv) accounting for autocorrelation
only or joint inversion of correlation and heteroscedasticity can be problematic
and requires special treatment. Although the conclusions of this study are empirical, the analysis may provide insights
for selecting appropriate data models for soil respiration modeling.
No Surrender: Bruce Springsteen, Neoliberalism, and Rock and Roll's Fantasy of Sovereign Rebellion
Authors: Graves Kaitlin N. 
Published: May 2019

Abstract
This article builds from press accounts of Bruce Springsteen's South by Southwest keynote address, taken by many to be a renewed call to arms of the classic mantras of the rock ethos in the age of a declining recording industry. In tracing the ways the speech circulated I argue that its discourse was rearticulated toward quite different (and concerning) ends. Throughout, I aim to show the apparatuses of power that sustains the rock liberation fantasy. I read the coverage of Springsteen's address as a therapeutic discourse meant to soothe the anxiety over the closure of agency in the age of neoliberalism. The article offers this case study as an example of the way that rock, in general is redirected away from rebellion and productive agency and toward neoliberal prescriptions of self-control and discipline. The article then, addresses an anxiety over the collapse of freedom and as such works to offer broad reflections on the nature of radical agency in our increasingly neoliberal present.

Published: May 2019

El trabajo que presentamos estudia la creatividad en estudiantes universitarios y las posibles diferencias por género, edad y elección de estudios que pudieran surgir, derivadas de una intervención en el aula basada en emociones positivas. Utilizamos un diseño cuasi-experimental con pre-test y post-test. La muestra estuvo formada por 206 estudiantes universitarios de Grado y de Ciclos Formativos de Grado Superior, que fueron evaluados con el test CREA (Corbalán Berná et al., 2003). Los resultados muestran que los estudiantes aumentan su creatividad después del programa de intervención, existiendo, además, diferencias estadísticamente significativas para los test de CREA formas A y B. Estas diferencias significativas también se hallan en la creatividad por género, mostrándose las mujeres más creativas, tanto en el pre-test como en el post-test, en el CREA forma B. En cuanto a la edad, son los alumnos más jóvenes, menores de 20 años, los que se manifiestan significativamente más creativos tanto en el pre-test como en el post-test, en el CREA forma B. Por último, en cuanto al ámbito educativo, aquellos alumnos pertenecientes al sector de la educación, muestran mayor índice de creatividad que el alumnado que cursa titulaciones de carácter no educativo, tanto antes como después de la intervención, con resultados significativos en el CREA forma B. Los resultados se discuten por su interés para el cambio educativo en la universidad hacia la empleabilidad y la igualdad de oportunidades en el desarrollo de competencias 2020.

Published: May 2019

Esta investigación analiza las necesidades de orientación y educación para la carrera de los estudiantes universitarios. Surge del desarrollo de una propuesta innovadora de Plan de Acción Tutorial de la Universidad de Oviedo, elaborada con los mismos principios que fundamentan los programas de educación para la carrera, en niveles anteriores del sistema educativo. Las importantes resistencias de un sector del profesorado a contribuir en la orientación profesional de sus alumnos, llevan a plantear la conveniencia de evaluar, con procedimientos rigurosos, la forma en la que actualmente se atienden estas necesidades de desarrollo de la carrera del alumnado en la Universidad. Por su interés en el proyecto, también participa la Facultad de Ciencias de la Educación de la Universidad de Córdoba. En este artículo se presentan las principales conclusiones sobre la orientación en relación al trabajo, que se proporciona a los estudiantes que se están formando para ser educadores (maestros de infantil y primaria, pedagogos y educadores sociales), en las Universidades de Oviedo y Córdoba. Se elabora y valida un instrumento específico para evaluar las necesidades de orientación en la Universidad (CENO-PAT), con sólidas cualidades métricas. Se trabaja con todos los estudiantes que asisten a clase, y se cuenta con una muestra de 2.414 personas que, con un nivel de confianza del 99%, representa óptimamente al alumnado de las dos Facultades, los seis Grados, y todos los cursos. Los estudiantes hacen una importante crítica a la orientación para el trabajo que reciben en la Universidad: están convencidos de que su futuro profesional, que es lo prioritario para ellos, no importa a la mayoría de sus profesores. Efectúan numerosas demandas relacionadas con su orientación y el desarrollo de su carrera. También aseguran que en muy pocas asignaturas se trabaja la necesidad de proteger el medioambiente en todos los contextos profesionales y personales.
Caractérisation géochimique des eaux d’irrigation de la palmeraie d’Oumache (oasis des Ziban, sud-est de l’Algérie)

Published: May 2019

L’ancienne palmeraie d’Oumache située à l’aval de Zab el Gharbi (ouest de Ziban-Biskra, sud-est de l’Algérie) connait aujourd'hui un déclin dû essentiellement à l’insuffisance de l’eau d’irrigation et à la remontée des eaux trop chargées de la nappe phréatique. De plus, le milieu endoréique très évaporant a accéléré le phénomène de salinisation du sol. Ce travail traite de la caractérisation géochimique des eaux (forage et nappe) utilisées pour l’irrigation en vue d’une meilleure gestion de l’irrigation. Les résultats montrent que l’eau de forage présente un risque élevé de salinisation des sols. La salinité est de type neutre, sulfaté calcique et magnésique. En revanche, les eaux de la nappe sont impropres à l’irrigation avec des risques très élevés de salinisation et d’alcalinisation des sol. Elles évoluent vers une voie saline neutre du type chloruré et sulfaté sodique (57 % des échantillons) à sulfaté et chloruré sodique. La calcite et le gypse ont tendance à précipiter, alors que l’halite et thenardite sont dissous par évaporation. La nappe s’écoule depuis la zone d’alimentation vers la sebkha de Chemoura qui constitue la zone d’accumulation. Pour remédier au problème, il est préconisé de mettre en place un plan de gestion durable de l’eau et de la salinité, comprenant notamment la réhabilitation du système de drainage de cette palmeraie afin d’évacuer les eaux salées. Enfin, l’extension de l’oasis devra prendre en considération cet aspect de gestion préventive en optant pour l’oued Djedi comme autre exutoire naturel.
Characterization of hole traps in MOVPE-grown p-type GaN layers using low-frequency capacitance deep-level transient spectroscopy

Abstract
Traps in MOVPE-grown Mg-doped GaN samples composed of p+/p−/n+ structures were investigated using low-frequency capacitance deep-level transient spectroscopy (DLTS). A drop-off in capacitance with decreasing temperature was observed. This is caused by the longer RC time constant of the diode with lower temperature, which is due to a decrease in the number of ionized Mg acceptors (which have a high ionization energy). This limits the use of lower temperatures in DLTS measurements. To extend DLTS to a lower temperature (105 K), DLTS using a capacitance measurement frequency of 1 kHz was applied. Thus, we can quantitatively discuss concentrations of traps with shallow energy levels. We obtained a nearly one-to-one relation between Ha (E
V +0.29 eV) and Hd (E
V +0.88 eV) in the p-type layer, which strongly supports the theoretical calculation that a carbon on a nitrogen site forms donor-like (Ha) and acceptor-like (Hd) states.
Management Strategies in Transnational Workspaces
Authors: Wagner Ines 
Published: May 2019

Chapter 3 combines institutional theory with strategic perspectives drawn from the sociology of organizations to examine how industrial relations actors “enact” EU rules at the micro-level of the workplace. The aim of this chapter, therefore, is to study how micro-level societal actors such as firms, unions, works councils, and individual workers interact with the changing regulatory configuration. It studies how employers enact the posting framework creatively by circumventing rules. This chapter demonstrates how these mechanisms initiate a process of institutional change through power dynamics at the micro-level that are generally relevant for theories about institutional change. In pursuit of a more nuanced understanding of the regulatory dynamics of posted work, this chapter identifies the ways in which actors draw on different power resources to influence the outcomes of negotiations or to implement policies without negotiation at the workplace level.
Boat anchoring contributes substantially to coral reef degradation in the British Virgin Islands
Authors: Flynn Rebecca L. , Forrester Graham E. 
Published: May 2019

Community decline is often linked to anthropogenic activities. Coral reef declines, for example, have been linked to overfishing and climate change, but impacts of coastal development, pollution, and tourism have received increasing attention. Here, we isolated the impact of one little-studied aspect of recreational activity on coral reefs—damage from boat anchoring—by performing a survey of 24 sites in the British Virgin Islands (BVI) subject to varying levels of anchoring activity. The percent cover of hard corals and sea fans was reduced by a factor of ∼1.7 and ∼2.6 respectively at highly anchored sites. Hard coral colonies were 40% smaller in surface area and ∼60% less dense at sites experiencing high anchoring frequency. In addition, highly anchored sites supported only ∼60% of the species richness of little anchored sites. Frequently anchored sites were ∼60% as structurally complex and supported less than half as many fish as those rarely anchored, with 5 of 7 fish functional groups affected. Roughly 24% of BVI coral reef by area appears suitable for anchoring, suggesting that impacts associated with boat anchoring may be both locally severe and more pervasive than previously appreciated.
A Short Review and the Prediction of Tumor Growth based on Numerical Analysis
Authors: Hossine Zakir , Meghla Afrina Asad , Kamrujjaman Md. 
Published: May 2019

In this study, we consider Murray’s and Glioma’s tumor growth models based on reaction- diffusion equation. Mathematical modeling of tumor development are involved with the associated experimental work, reasoning the final relationship between experimental and theoretical approaches and these lead a path to model the prediction of tumor growth. Initially, we study the primary model of tumor growth which is connected with the ordinary differential equations and finally extended the problem to reaction-diffusion models. We predict the tumor growth model using numerical study and the observation in different zone of time. The goal of tumor growth prediction is to model the tumor growth process, which can be achieved by theoretical mathematical modeling collaboration with the model personalization from clinical assessment. After certain time period, it is shown that the mathematical model shows the tumor cell population reaching a maximum cell number that the tissue can carry.
