ARTIFICIAL INTELLIGENCE TECHNIQUES FOR PREDICTING TIDAL EFFECTS BASED ON GEOGRAPHIC LOCATIONS IN GHANA
Authors: Issaka Yakubu , Kumi-Boateng Bernard
Published: April 2020

Tidal forces as a result of attraction of external bodies (Sun, Moon and Stars) through gravity and are a source of noise in many geoscientific field observations. The solid earth tides cause deformation. This deformation results in displacement in geographic positions on the surface of the earth. The displacement due to tidal effects can result in deformation of engineering structures, loss of lives, and economic cost. Tidal forces also help in detecting other environmental and tectonic signals. This study quantifies the effects of solid earth tides on stationary survey controls in five regions of Ghana. The study is in two stages: firstly, the solid earth tides were estimated for each control by a geometric approach (combining Navier’s equation of motion and Love theories). Secondly, estimation using two artificial intelligence methods (Multivariate Adaptive Regression Splines (MARS) and Backpropagation Artificial Neural Network (ANN)). Based on statistical indices of Mean Square Error (MSE) and Correlation Coefficient (R), BPANN, and MARS models can be used as a realistic alternative technique in quantifying solid earth tides for the study area. The MSE and R (MSE; BPANN = 1.3249 × 10–04 and MSE; MARS = 2.2052 × 10–06; R; BPANN = –0.6067 and R; MARS 0.6570) values indicate that MARS outperforms BPANN in quantifying solid earth tides in the study area. BPANN and MARS can be used as an efficient tool for quantifying tidal values based on geographic positions for geodetic deformation studies within the study area.
INVESTIGATION INTO THE HYDRODYNAMIC PROCESSES OF FITTING CONNECTIONS FOR DETERMINING PRESSURE LOSSES OF TRANSPORT HYDRAULIC DRIVE
Authors: Karpenko Mykola , Bogdevičius Marijonas
Published: April 2020

The article presents the findings of theoretical and experimental research on hydraulic processes occurring
in the hydraulic drives of transport machines. The paper analyses the influence of hydrodynamic processes on the flow characteristics
of fluid considering different hydraulic fitting connections. The performed analysis is based on numerical simulations using
Navier–Stokes equations for the velocity field. The dynamics of fluid flow in the hydraulic system has been investigated taking into
account the main parameters like system flow rate in the range of 5 to 100 L/min, the diameter of the pipeline making 1/2” and fitting
standards DKOL, ORFS, BSP and JIS. As a result, pressure drop, power losses, resistance and flow coefficients at different fitting
connections have been obtained. The article compares the provided results with the findings given employing the calculation method
for the standard of equivalent length fitting. To simulate fluid flow, a mesh independence study and turbulence calculations have been
performed. Simulation results have been examined conducting physical experiments on measuring pressure losses. Each experimental research
includes three measurements of connections bearing in mind each fitting standard.
Earth’s Polar Night Boundary Layer as an Analog for Dark Side Inversions on Synchronously Rotating Terrestrial Exoplanets
Authors: Joshi M. M. , Elvidge A. D. , Wordsworth R. , Sergeev D.
Published: April 2020

A key factor in determining the potential habitability of synchronously rotating planets is the strength of the atmospheric boundary layer inversion between the dark side surface and the free atmosphere. Here we analyze data obtained from polar night measurements at the South Pole and Alert Canada, which are the closest analogs on Earth to conditions on the dark sides of synchronously rotating exoplanets without and with a maritime influence, respectively. On Earth, such inversions rarely exceed 30 K in strength, because of the effect of turbulent mixing induced by phenomena such as so-called “mesoscale slope winds,” which have horizontal scales of 10–100 s of km, suggesting a similar constraint to near-surface dark side inversions. We discuss the sensitivity of inversion strength to factors such as orography and the global-scale circulation, and compare them to a simulation of the planet Proxima Centauri b. Our results demonstrate the importance of comparisons with Earth data in exoplanet research, and highlight the need for further studies of the exoplanet atmospheric collapse problem using mesoscale and eddy-resolving models.
A classification of endangered high-THC cannabis (Cannabis sativa subsp. indica) domesticates and their wild relatives
Authors: McPartland John M. , Small Ernest
Published: April 2020

Two kinds of drug-typeCannabisgained layman’s terms in the 1980s. “Sativa” had origins in South Asia (India), with early historical dissemination to Southeast Asia, Africa, and the Americas. “Indica” had origins in Central Asia (Afghanistan, Pakistan, Turkestan). We have assigned unambiguous taxonomic names to these varieties, after examining morphological characters in 1100 herbarium specimens, and analyzing phytochemical and genetic data from the literature in a meta-analysis. “Sativa” and “Indica” are recognized as C. sativa subsp. indica var. indica and C. sativa subsp. indica var. afghanica, respectively. Their wild-growing relatives are C. sativa subsp. indica var. himalayensis (in South Asia), and C. sativa subsp. indica var. asperrima (in Central Asia). Natural selection initiated divergence, driven by climatic conditions in South and Central Asia. Subsequent domestication drove further phytochemical divergence. South and Central Asian domesticates can be distinguished by tetrahydrocannabinol and cannabidiol content (THC/CBD ratios, ≥7 or <7, respectively), terpenoid profiles (absence or presence of sesquiterpene alcohols), and a suite of morphological characters. The two domesticates have undergone widespread introgressive hybridization in the past 50 years. This has obliterated differences between hybridized “Sativa” and “Indica” currently available. “Strains” alleged to represent “Sativa” and “Indica” are usually based on THC/CBD ratios of plants with undocumented hybrid backgrounds (with so-called “Indicas” often delimited simply on possession of more CBD than “Sativas”). The classification presented here circumscribes and names four taxa ofCannabisthat represent critically endangered reservoirs of germplasm from which modern cannabinoid strains originated, and which are in urgent need of conservation.
Validation of the Simulation Effectiveness Tool in Nursing Education
Authors: Shin Hyunsook , Kim Hyojin , Rim Dahae , Ma Hyunhee , Shon Soonyoung
Published: April 2020

Background:

The Simulation Effectiveness Tool (SET) frequently is used to assess perceived learning and confidence in simulation. However, few studies have reported the validity of the tool. This study assessed the reliability and validity of the SET.

Method:

This retrospective analysis evaluated the tool using 568 cases conducted at three nursing schools.

Results:

A two-factor model showed reasonable fit indices. The fit statistics for the two-factor structure were: χ
2
, 152.98 (
df
= 53,
p
< .001); comparative fit index, 0.94; root mean square error of approximation, 0.05 (range, 0.04 to 0.06); and standardized root mean square residual, 0.04. In addition, weak convergence was identified between the confidence in the SET and responding in the Lasater rubric.

Conclusion:

The psychometric properties of the study indicate the SET has demonstrated acceptable evidence of validity and reliability to measure simulation effectiveness in Korean nursing students. The use of this instrument for brief simulation education is recommended.

Understanding and Negotiating Contracts With Venues
Authors: Nolan Emma
Published: April 2020

Signing the venue hire contract is a significant stage in the event planning process as it formalises the agreement with the principal supplier to the event. Venue contracts can be quite lengthy and detailed documents as they cover all aspects of the agreement between the two parties. As well as confirming the hire charges, it will stipulate a number of rules and regulations that will govern the event, and it will outline the penalties for failing to comply with the contract. Much of this is rooted in the venue's plan to ensure that the event complies with relevant legislation and health and safety guidance. This chapter covers the purpose of a venue contract, typical terms and conditions, likely penalties for breaching the contract, plus an overview of venue specific laws and health and safety guidance.
Media and Ideology
Authors: Özdoyran Güven
Published: April 2020

This chapter aims mainly to provide a framework towards the sophisticated relation between “media” and “ideology” by putting the key thinkers' arguments, such as Marx, Gramsci, Althusser (and also Zizek's and Hall's complementary contributions), at the center. In order to fulfill this aim, the chapter will, firstly, elaborate on Marx's conception of ideology, as Marx's understanding of “ideology,” “human being,” and “the world” directly determines not only the direction and but also the content of the debates on media and ideology. Secondly, Gramsci's theory of “hegemony” will be scrutinized. In this way, the view claiming that the primary function of media is to produce “hegemony” through which the capitalist class maintains its own privileged position in society will be discussed. Finally, the chapter will discuss Althusser's notion of “ideology” and “ideological state apparatus.” Thus, the reader will notice the way how media and ideology mutually include each other.
Social Media Economy and Newsroom Convergence in Egyptian Media
Authors: El Gody Ahmed
Published: April 2020

In Egypt, for the past 20 years, several news organizations began to diffuse ICT resources in the news-making processes to attract a larger audience. Soon, the utilization of new technologies has altered the traditional newsgathering and production formats changing the nature of journalism practices and routines. The success of newsrooms, especially in post-Egyptian revolution era is measured in their ability to adopt, integrate, and utilize ICTs in all processes of production to satisfy their readers. This study focuses on the diffusion and implementation of social media in Al Ahram newsroom. Further, the study examines if/and to what extent and in what ways did Al Ahram newsroom incorporate ICTs in their daily routine. Other questions are as follows: What are the ICTs components that are diffused and adopted in the Egyptian print media?, What are the form(s) of networking among journalists and their networking strategy –if any– with their sources, editors and audience?, Is there a convergence strategy or strategies within the Egyptian newsrooms? And if so, what is it/are they?
Political Economy of the Relationship Between Crony Capitalism and the Private Television Channel Boom in Bangladesh
Authors: Khan Abdur Razzaque
Published: April 2020

Bangladesh noticed a boom of private television channels in 2001 when the Bangladesh Nationalist Party (BNP) government gave 10 private TV licenses to its cronies, brushing aside all rules and regulations. Private TV owners are present or former members of Parliaments (MPs), ministers, and the ruling party's leaders and cronies. They were imprisoned with heavy corruption charges during the period of the army-backed caretaker government. Then, Sheikh Hasina committed to bringing private television channels under strict rules and regulations. The Bangladesh Awami League (AL) formed the government in 2009 under the leadership of Sheikh Hasina and started to give private TV channel licenses to its cronies. The private TV boom is very much political and an easy way to convert the black money of the country's crony capitalists into white. This chapter concentrates on the very symbiotic relationship between crony capitalism and the private TV boom in Bangladesh and its critical political economy.
Epidemiology of Inflammation-Related Diseases
Authors: Tarı Selçuk Kevser
Published: April 2020

Inflammation, a vital defense mechanism for health, is defined as the immune system's response to harmful stimuli such as pathogens, damaged cells, toxic compounds or irradiation. Inflammation is usually examined in two groups: acute and chronic. Chronic inflammation instigates various kinds of diseases that cause premature mortality and morbidity such us cardiovascular diseases, cancer, diabetes mellitus (DM), asthma-chronic obstructive pulmonary disease (COPD), obesity, metabolic syndrome (METs), inflammatory bowel disease (IBD), rheumatoid arthritis (RA), multiple sclerosis (MS), osteoporosis, and neurological diseases via dysregulation of various signaling pathways such as nuclear factor kappa-B (NF-κB), signal transducer, activator of transcription 3 (STAT3), etc. These inflammation-related diseases are among the major causes of mortality and morbidity in almost every region of the world. Studies have shown that these diseases associated with inflammation have tended to increase worldwide.
Macronutrients Having Pro-/Anti-Inflammatory Properties
Authors: Günşen Uğur , Atan Ramazan Mert
Published: April 2020

Inflammation is a physiological response to infectious agents and tissue damage. When the inflammatory process does not proceed appropriately, a low-grade chronic inflammatory response develops. Low-grade chronic inflammation is defined as a metabolic process characterized by the increase of the acute phase proteins such as CRP and the pro-inflammatory cytokines in plasma and by infiltration of macrophage and T cell and of chemotactic pro-inflammatory chemokines such as monocyte chemotactic protein-1 (MCP-1) in insulin-dependent tissues cells. Carbohydrates, fats, and proteins, which are among the most important macro nutrients are important for the individual's inflammatory response according to their daily intake levels, sources and types. Although their diet is rich in complex carbohydrates, pulp, MUFA, PUFA, the reduction of SFA, TFA, simple sugars, and processed carbohydrates can lead to positive effects on inflammatory pathways and prevent chronic diseases in the long term.
Faculty Socialization and Gaining Tenure
Authors: Olszewski Carol A. , Hansman Catherine A.
Published: April 2020

In higher education, ethical principles should guide administrators to develop policies and procedures that are just and fair to faculty, administrators, staff, and students and, as well, consider the needs of the various stakeholders affected by them. One example of a process that should be planned and carried out in an ethical way is the tenure-track process for faculty members. The purpose of this chapter is to discuss ethical issues and challenges institutions of higher education face in the tenure process and in socializing new full-time tenure track faculty members into academe. The authors discuss the acculturation process into the academy, then focus on interpersonal interactions and relationships, including mentoring and other supportive relationships and gender and minority issues that may affect the tenure process and acculturation into the academy. They conclude with future concerns and discussion of the ethical considerations for socializing faculty members into academe.

Published: April 2020

Distance education programs in the form of online instruction continue to grow in terms of enrollments as well as courses available. However, consideration of the values promoted by ideal distance and open learning systems may not be guiding the design and development of such programs. The values of access, availability, affordability, continuity, connection, independence equity can form the basis for a conversation on how a program is realizing the promise of distance education given the constraints of institutional mission, culture, and business/academic model.

Authors: An Zi Liang , Wang Zi Ye , Tang Yi Feng , Wang Wei Xin
Published: April 2020

The dynamic measurement model for the interface cavities of the diffusion welded joint, which based on the effective resistivity, is established by using the damage factor and the Derby Model of the Bridgman Law. Then the quantitative relationship, which between the direct current potential and the effective area of the joint at high temperature and high pressure, can be obtained. In addition, on the basis of the dynamic four-probe DC potential method and the fieldbus technology, the computer measuring system is established, so that the creep propagation behaviour for the interface cavities of the 316L stainless steel can be monitored in real-time.
Microscopic Molecular Assembly and Catalytic Mechanism of Rare Earth-Alumina Nanocomposite Devoted to Reducing PM2.5
Authors: Zhao Ting Feng , Zeng Qi Hui , Hao Bao Hong , Zeng Ding
Published: April 2020

Automobile exhaust is one of the sources of PM2.5, which can merely be catalytically decomposed by a "post-treatment" three-way catalytic device at present. Afront-treatment device based on rare earth-alumina nanocomposite in gasoline was innovatively introduced. nanoalumina and rare earth elements are function as the backbone and carrier, respectively. Microscopic molecular assembly and catalytic mechanism were studied to synthesize metastable ordered mesoporous with high degree of aggregation. Mesh filter of rare earth-alumina nanocatalytic composite with self-sustained release function is formed by sintering, which can be solidified in an automotive air intake system. Results show that rare earth-aluminum nanocomposite contributes to catalytic combustion and makes combustion more complete. Moreover, it has a better effect of reducing PM2.5 than a "post-treatment" device in terms of catalytic effect.

Mobility-aware dynamic service placement for edge computing
Authors: Liu Gang , Wang Jiawei , Tian Yumin , Yang Zhenhua , Wu Zhenping
Published: April 2020

Edge computing provides capabilities similar to traditional cloud computing at network edge closer to users. Oﬄoading applications from the cloud to the edge of the network can eﬀectively diminish the latency of users waiting for applications to improve their quality of service(QoS). Due to the user mobility, however, the distance between the user and the edge device is constantly increasing, resulting in a degradation of the user’s QoS. To satisfy the QoS of mobile users, applications should be dynamically migrated to follow the user mobility. In this paper, we propose a mobility-aware dynamic service placement policy that reduces the number of virtual machine migrations and diminishes user-perceived latency simultaneously. The proposed scheme ﬁlters out the invalid migration that the user handoﬀs to another access point before the migration is completed. The simulation trials demonstrate that our solution improves the QoS of users and reduces the number of application migrations.

A Study on Membrane Filtration Characteristics of Methanogenic Mixed Liquor in Two Phase Anaerobic Digestion of Food Waste
Authors: Park Min-Ju , Seo Gyu-Tae
Published: April 2020

Objectives:An experimental study was conducted to investigate the membrane filtration characteristics of mixed liquor in methanogenic reactor to extend solid retention time (SRT) in food waste anaerobic digestion system.Methods:On the basis of the particle size distribution (0.5~700 µm) of the methanogenic mixed liquor, three grade membranes (MF, UF, NF) were tested in a stirred cell filtration and a plate type module. Furthermore foulants of membrane, especially UF, was investigated by SEM-EDS, FTIR, SEC.Results and Discussion:As a result UF membrane was selected for stable filtration of the liquor in terms of flux (2.51 L/m2･h･bar) and the flux recovery (100%) as well as filtration resistance (Total 7.15.E+13 m-1). Average flux was 18 L/m2･h･bar for the selected UF membrane in cross flow filtration using a flat plate module. The filtration results showed that membrane fouling was caused by gel and cake layer formed on the membrane surface and 90% of the initial flux could be recovered by physical washing. It was identified that major fouling causing materials were byproducts of carbohydrate and protein decomposition, and small amount of inorganic substance detected on the membrane surface were salt and struvite like materials.Conclusions:Based on the membrane filtration characteristics analyzed from the study, the UF membrane coupled anaerobic digestion is feasible to be applied as a novel food waste treatment system for SRT extension of the methanogenic reactor.

Scientists' warning on endangered food webs
Authors: Heleno Ruben H. , Ripple William J. , Traveset Anna
Published: April 2020

Abstract. All organisms are ultimately dependent on a large diversity of consumptive
and non-consumptive interactions established with other organisms, forming
an intricate web of interdependencies. In 1992, when 1700 concerned
scientists issued the first “World Scientists' Warning to Humanity”, our
understanding of such interaction networks was still in its infancy. By
simultaneously considering the species (nodes) and the links that glue them
together into functional communities, the study of modern food webs – or
more generally ecological networks – has brought us closer to a predictive
community ecology. Scientists have now observed, manipulated, and modelled
the assembly and the collapse of food webs under various global change
stressors and identified common patterns. Most stressors, such as increasing
temperature, biological invasions, biodiversity loss, habitat fragmentation,
over-exploitation, have been shown to simplify food webs by
concentrating energy flow along fewer pathways, threatening long-term
community persistence. More worryingly, it has been shown that communities
can abruptly change from highly diverse to simplified stable states with
little or no warning. Altogether, evidence shows that apart from the
challenge of tackling climate change and hampering the extinction of
threatened species, we need urgent action to tackle large-scale biological
change and specifically to protect food webs, as we are under the risk of pushing
entire ecosystems outside their safe zones. At the same time, we need to
gain a better understanding of the global-scale synergies and trade-offs
between climate change and biological change. Here we highlight the most
pressing challenges for the conservation of natural food webs and recent
advances that might help us addressing such challenges.
Impactos da legislação eleitoral sobre a comunicação política e a decisão de voto
Authors: Carmo Fernandes Luiz Carlos
Published: April 2020

Propôs-se discutir os impactos da legislação eleitoral sobre o HGPE. Tomando como base um estudo de caso sobre as eleições municipais de 2016 em Goiânia, tentou-se verificar se as alterações feitas nas regras eleitorais a partir de 2006, com o intuito de coibir o abuso do poder econômico e a manipulação da preferência eleitoral, também têm dificultado a comunicação política. Para tanto, usou-se uma associação de metodologias qualitativas e quantitativas: entrevista em profundidade com pesquisadores acadêmicos, profissionais de campanha eleitoral e o próprio eleitor; além de análise de conteúdo das propagandas eleitorais de televisão, utilizando as categoria analítica das fases das campanhas de Ferraz (2004) e a metodologia para identificar as estratégias de comunicação política de Figueiredo et al. (2000). Ao final, concluiu-se que as mudanças na legislação eleitoral de 2016 impactaram os partidos políticos e os candidatos, mas muito pouco o eleitor.

Experiences of Student Nurses on the Use of the Two-Week Block System at the Satellite Campus of a Higher Education Institution in Namibia
Authors: Shatimwene Gelasius Panduleni , Ashipala Daniel Opotamutale , Kamenye Esther
Published: April 2020

Clinical Training is intended to prepare nursing students for future nursing practice in both private and public facilities. As do many nursing training institutions globally, this Higher Education Institution (HEI) uses the two-week block system as a teaching system. However, despite the two-week block system, it would appear that, due to the increased number of nursing students, the aligning of practical exposure with theoretical instruction is becoming difficult in balancing theory and practice for both student and academics. Such alignment requires institutions of higher learning to establish which teaching systems are likely to promote the correlation between theory and practice. The experiences of students may be used to identify positive learning environment for students. This study aimed to explore and understand the personal experiences of student nurses studying at Higher Education Institution HEI in Namibia in relation to the use of the two-week block system. The objectives of the study included exploring and describing the experiences of student nurses regarding the two-week block system at the HEI with a view to ascertaining the negative impact, if any, of such a teaching system on their studies. A study employed a qualitative approach which comprised an explorative and descriptive research design, using purposive sampling. The research population in the study consisted of first to fourth year, undergraduate nursing students who were studying at a satellite campus of a HEI in Namibia. The requisite data was collected from four focus group discussions which were each conducted with six to seven participants. The transcribed interviews and narratives from the research notes were then organised into main themes and sub-themes. Three main themes and nine sub-themes were identified. The findings of the study indicated that two-week block system was associated with challenges as was evidenced by the following themes that had emerged from the study, namely, different experiences of the two-week block system, various effects of the two-week block system and recommendations to School of Nursing (SoN).The study recommended that the HEI extend the two-week block system to a one-month block system in order to give the students sufficient time in which to put the theory they have learnt into practice.
Effects of Climatic Variability and Non-Climatic Factors on Mopane Worms’ (Gonimbrasia Belina) Distribution and Livelihood Options in North Central Namibia
Authors: Togarepi C. , Nashidengo E. , Siyambango N.
Published: April 2020

Mopane worms (Gonimbrasia belina) are an important source of food and income for households in Northern Namibia. However, their access and availability in many areas have declined, mainly due to climate change and human activities. This has affected many households’ livelihoods, making them vulnerable to poverty and food insecurity. With these factors in mind, this study sought to identify the extent to which the availability and distribution of mopane worms are influenced in the Tsandi and Okahao constituencies. The study used structured questionnaires to collect information from households in the study area, to interview key informants, and to carry out group discussions. A total of 70 households and 6 key informants were interviewed, along with 4 focus group discussions that were carried out to elicit perceptions, and to obtain views on the availability of mopane worms, and possible causes of the decline in the study area. Data were analysed using descriptive statistics, while GIS was used to determine trends in vegetation cover, temperature and rainfall in the area. The rainfall trend indicates variability, with a generally declining trend. A slight increase in temperature has been observed too. Vegetation showed a browning trend in the study area, indicating declining habitats of mopane worms. The results have indicated that more women depend on mopane worms for survival, mainly as a source of income. Thus the decline in their availability greatly affects their food sources and their income diversification opportunities. Trading was found to be an important form of employment for the unemployed rural people, but with the potential to generate higher income levels that can improve their livelihoods. Moreover, despite the climatic factors, human activities seemed to indicate a greater influence on the availability of mopane worms, due to activities such as overharvesting, land clearing for agriculture and household use/fencing. Thus, there is a greater need to control the harvesting of mopane worms and to control tree cutting activities in order to reduce the impacts of climatic and non-climatic factors on their availability.
Antimicrobial susceptibility of multi-drug and extensively-drug-resistant Escherichia coli to ceftolozane-tazobactam and ceftazidime-avibactam: An in vitro study*
Authors: Zalas-Więcek Patrycja , Gospodarek-Komkowska Eugenia

Aim: Escherichia coli is one of the Gram-negative bacteria, known to cause many nosocomial infections. Multi-drug (MDR) and extensively-drug resistant (XDR). E. coli are of particular note, due to significant limitations in antibiotic therapy. Ceftolozane-tazobactam and ceftazidime-avibactam are novel therapeutic options against Gram-negative bacteria; hence the aim of this study was to evaluate and compare the  in vitro  activity of ceftolozane-tazobactam and ceftazidime-avibactam against MDR and XDR clinical E. coli isolates. Material/Methods: The study included 100 non-replicate E. coli isolates derived from clinical samples of patients hospitalized in teaching hospitals. Bacteria were identified by applying mass spectrometry in the MALDI Biotyper system (Bruker). ESBL (blaCTX-M-1group, blaCTX-M-9group) and carbapenemase (blaKPC, blaVIM, blaNDM, blaOXA-48, blaOXA-181) genes were detected using the eazyplex® SuperBug CRE test, based on a loop-mediated isothermal amplification (LAMP). The in vitro susceptibility to ceftolozane-tazobactam and ceftazidime-avibactam was tested using validated MIC Test strips (Liofilchem). Results: All 84 extended-spectrum β-lactamase-producing (ESBL) E. coli isolates were susceptible to ceftazidime-avibactam and 83 to ceftolozane-tazobactam. Among 17 E. coli isolates with resistance to at least one of the carbapenems, three (17.6%) were susceptible to ceftolozane-tazobactam and ceftazidime-avibactam. All 14 blaVIM gene-positive E. coli isolates were resistant to both ceftolozane-tazobactam and ceftazidime-avibactam. Both antibiotics were active against blaCTX-M-9group and blaOXA-48 gene-positive E. coli isolates, but they were not active against blaCTX-M-1group and blaVIM gene-positive isolates. Conclusions: Ceftolozane-tazobactam and ceftazidime-avibactam are alternative, non-carbapenem therapeutic options for ESBL-positive E. coli strains, and they are promising in the treatment of carbapenem-resistant E. coli strains, but not for those carrying the metallo-β-lactamase enzymes. Both drug combinations have comparable activity against ESBL, however, lower MIC values were found for ceftazidime-avibactam.
Circos brasileiros de lona, um campo em constante movimento e transformação simbólica

This paper analyzes the circus universe, that is, the circuses and the individuals involved in the daily activities to create, maintain, and develop the circus organization, and is based on Pierre Bourdieu’s field theory. Empirically, we sought to build a qualitative and diversified corpus based on 28 circuses and 116 interviews, as well as recorded conversations, newspaper articles, and by accompanying circuses and watching performances. Particularly, the semi-structured interviews based on the “snowball” technique have the people who work, live, and roam with and in the circus as a common element. Seeking to resist stereotypes and give voice to those who create organizations, we conducted this study so that the various voices of the agents in the field are heard, which, in turn, clarifies how the circus subjects and organizations (the actual circuses) are built and intertwined. No clear domination of an agent over the other has been identified in the field. Except for the legal difficulties pointed out by smaller circuses, power relations are much more visible when it comes to staying in the field. The further the agents are from accessing the symbolic and power resources, the more they are subjected to disappearance or precarious continuity.
CEO duality e desempenho organizacional: evidências no mercado brasileiro de capitais
Authors: Costa Yngrid Cabral Lima da , Martins Orleans Silva
Published: April 2020

CEO duality is the practice in which the Chief Executive Officer (CEO) has both the presidency of the company as the chairman of its Board of Directors. The literature so far shows the positive and negative impact on organizational performance when this happens. The approach of the Agency theory suggests that these two functions should be exercised by different people. Therefore, this study aimed to verify the relationship between CEO duality and the corporate performance of companies listed on the Brazil Index (IBrX100) in the 2008 to 2013 period. The sample comprised 70 companies, totaling 420 observations in a balanced panel data. To investigate the relationship proposed by this study, two statistical strategies were used: the method of Ordinary Least Squares and Probit. The results showed that the duality did not affect the organizational performance when compared to the other explanatory variables. However, the performance was affected by the boar size and by the share concentration, as they were the only significant variables, meeting the findings of Daily and Dalton (1997) and Moscu (2013). This result confirms the premise that when duality exists, decisions generally tend to be centralized to avoid loss of control by managers.
Diferenças entre as práticas de ambientes de inovação de sistemas nacionais de inovação com maturidades distintas: evidências do caso brasileiro e francês
Authors: Mathieu Patrícia Benassi , Delai Ivete
Published: April 2020

The aim of this study is to identify the different practices that exist in innovation environments that belong to National Innovation Systems with distinct maturity levels: France (advanced) and Brazil (in development). A case study was carried out comparing the Technological Park of São José dos Campos and the Pôle de Compétitivité HYDREOS regarding seven dimensions: governance, strategy, external relationships, external environment, legal context, infrastructure and funding mechanisms. As a result, the initial premise that the environment inserted into the mature system presents a more comprehensive set of the studied dimensions can be observed. The main differences identified (or improvement opportunities for the Brazilian environment) refer to the following dimensions: external relations, strategy, funding mechanisms and governance. Most of these differences directly affect the degree of interaction between the members of the innovation environment and between them and outsiders, the diversity of actors and the relationship rules, which are key elements of a national innovation system.

Published: April 2020

Marketing metrics are a way of proving the result of marketing efforts and ensure its relevance inside companies. Big Data can be an opportunity for marketing to gain even more importance since access to a greater volume of information makes possible to develop new metrics. The present paper verifies if this is a reality on marketing departments, if the department is involved in developing or reporting metrics, and in the use of Big Data. To achieve this goal, first, we develop premises from the literature so that, after, we can confront it with reality, captured by interviews with marketing practitioners that work on different economic sectors. We intend to present possibilities for future research and to foster discussion about the marketing department responsibility to present metrics about the results of its actions.

This study analyzes how the policies and practices of personnel management directed at individuals with disabilities in João Pessoa, PB, Brazil, are configured concerning their insertion and inclusion into the labor market. For such, a quantitative research of descriptive character was conducted using the survey method. The research was developed with individuals, with and without disabilities, who worked and resided in João Pessoa. In total, 90 individuals partook of the study, 45 of which presented disability while the other 45 presented none. The questionnaire was applied in person and made available on the internet by means of the Google Docs system. Data analysis was done using SPSS, consisting of a factorial and descriptive analyses, analysis of variance (ANOVA) and non-parametric tests Kruskal-Wallis and median. The results demonstrated that, despite the individuals with disabilities perceiving an evolution of personnel management policies and practices applied by the organizations regarding the manner of capturing, accepting and coexisting with individuals with disabilities, they are not yet enough to assure their effective inclusion in the labor market.

This paper aims to identify the key business processes that are part of the organization structure in law firms that provide legal services. The study was conduct within the legal administration and business process management approaches. A qualitative-exploratory and quantitative-descriptive research was realized. The first, conducted through the application of semi-structured individual interviews, identified eight theoretical dimensions that were used in the latter, as a reference for defining the research questionnaire. Seven law firms certified by ISO 9001 were used for the identification of business processes. As results the identified processes were grouped according to APQC Process Classification Framework, in four key process (vision and strategy development, service market, products and services distribution and customer service management). Also, six support process categories were identified: information technologies management, financial resources management, acquiring, constructing and management properties, environmental health and safety, external relationships management and management knowledge, improvement, and change. Providing greater customer satisfaction has been identified as the main factor for the offices to map their business processes, while lesser degree of importance was attributed to product and service cost reduction and quality improving.

This study was developed along with companies which received the Human Resources Distinction Awards for their achievements in strategic management of people from 2010 to 2014, awarded by the Human Resources Association of Serra Gaúcha (ARH Serrana). It aimed to understand how these companies awarded by ARH Serrana establish their ethics committees, and develop, communicate and implement their codes of ethical conduct. Data collection was performed with Qualtrics, and content analysis technique was used to analyze a script of open questions based on a qualitative approach. Data collection revealed that participants are aware of the importance of a code of ethics. However, based on the participants’ answers, it is noticeable that the establishment of a committee and the methodology employed to develop a code of ethics are not given the importance they deserve. ARH Serrana not only can convene management professionals but also could serve as a resource for developing the committees as well as the methodologies for establishing the code of ethics thus facilitating the organization’s ethical behavior.
