Push and Pull Motivations as Demand Predictors of Coastal and Marine Destinations: A Study in Acapulco, Mexico

ABSTRACT Many tourists look for coastal and marine destinations where they can perform various natural and cultural activities. This study addresses the dimensions of push and pull motivations that influence a coastal and marine destination for domestic tourism, and an analysis was performed with the dimensions of push and pull motivations that predict satisfaction, return and destination recommendation. For this purpose, a quantitative study of 441 surveys, where the researchers used data reduction and multiple regression techniques to select the motivational variables that predict a future behavioral variable, was carried out in Acapulco, a relevant coastal and marine destination in Mexico. Findings revealed two motivating dimensions of thrust that were “novelty” and “escape” and two dimensions of attraction that were “static marine” and “active marine,” The "novelty" and "static marine" factors mainly influenced satisfaction, while the factors that mostly predict return and recommendation were "escape" and "novelty. ”
Produção e comercialização de mirtilo: estudo de caso em uma empresa familiar

O mirtilo é uma fruta rica em antioxidantes naturais, sais minerais e vitaminas. Considerada um alimento da moda, a fruta possui propriedades para desacelerar o envelhecimento e auxiliar na prevenção de doenças. Neste trabalho, analisou-se, sob as premissas da Teoria dos Stakeholders, a percepção dos stakeholders sobre aspectos que impactam no negócio de produção e comercialização dessa fruta por uma empresa familiar. Foi desenvolvido um estudo de caso qualitativo, orientado pela Teoria dos Stakeholders, com dez entrevistas semiestruturadas com cada um dos representantes dos grupos de acionistas, empregados, clientes, fornecedores, credores e da sociedade – sem estes, segundo as premissas da teoria, a empresa deixaria de existir. Uma vez que é dependente dos stakeholders, a empresa familiar deve planejar e executar as atividades sob a ótica da Teoria dos Stakeholders. Este trabalho contribui para a teoria com a evidência de que os stakeholders possuem relação direta com a empresa familiar e geram valor sustentável, social e econômico. Como contribuição prática, são desenvolvidas categorias de análise da empresa familiar, ligando-as às perspectivas da Teoria dos Stakeholders, e evidenciadas as diferentes percepções dos stakeholders e de uma gestão para relacionamentos benéficos, em que todos podem contribuir e obter ganhos. Aponta-se como fator limitante o estudo de um caso único, isto é, se ampliada a amostra, pode-se gerar viés nos resultados. Sugere-se para estudos futuros expandir a amostra e avaliar como as empresas familiares podem medir a influência dos stakeholders na geração de valor sustentável, social e econômico.
Multiple-Model Estimation-based Prognostics for Rotating Machinery

Data-driven based prognostics approaches are currently attracting unprecedented attention. Considering flexibility, statistical model based prognostics, which present more transparency and usually incorporate statistical models with stochastic filtering, are studied in this paper. Traditionally, versions of Kalman filter and Particle filter are combined with a single statistical model. However, the service life of a bearing could undergo several health stages, such as a normal stage, a slight degradation stage, and a severe degradation stage. Thus, a single model cannot represent well the full degradation process of a bearing. As such, the concept of Multi-Model Estimation (MME) has been introduced in the field of CM of rotating machinery. Initially the Switching Kalman Filter (SKF) has been proposed combining three linear statistical models, but the Classic Kalman filter (CKF) might be insufficient for nonlinearity estimations. In this paper, we extend MME from CKF to nonlinear system estimation, for instance with extended Kalman filter, unscented Kalman filter and Particle filter, which can well overcome the drawbacks of CKF. Besides, twelve statistical models are studied and used for the automatic switch in the proposed multi-model methodology. The methodology is tested and evaluated on fifteen experimental datasets and it can be concluded that the extended MME outperforms the classic switching Kalman filter.
Variação temporal das taxas de vacinação contra a brucelose bovina no Sudoeste Goiano

A brucelose bovina é uma enfermidade infecciosa, crônica e de notificação obrigatória, responsável por inúmeras perdas econômicas e estabelecimento de barreiras sanitárias. O estudo foi realizado com o intuito de analisar a tendência de longo prazo das taxas de vacinação na microrregião do Sudoeste Goiano, no período de 2015 a 2020. Calculou-se as taxas de vacinação contra a brucelose bovina para, posteriormente, realizar os cálculos de tendência temporal de vacinação e suas análises. Os dados de vacinação do rebanho bovino, do período em questão, foram fornecidos pela Agência Goiana de Defesa Agropecuária (Agrodefesa), Goiânia-Go. No Sudoeste Goiano, a taxa de vacinação contra a brucelose foi de 59% no primeiro semestre de 2015, e de 35% no segundo semestre do mesmo ano. Em 2017, no primeiro semestre, a taxa foi de 54%, e de 29% no segundo semestre. No primeiro semestre de 2018, a taxa de vacinação observada foi de 48%, e de 25% no segundo semestre. No primeiro e segundo semestres de 2019, foram observadas, respectivamente, taxas de vacinação de 58% e 29%. Por fim, no primeiro semestre de 2020, observou-se uma taxa de 58%. A média das taxas de vacinação nos semestres avaliados foi de 44%. A menor taxa de vacinação foi observada em Chapadão do Céu (8%) no segundo semestre de 2017, com taxa de variação semestral de – 15,13% (IC95% - 28,7 a 1). Santa Rita do Araguaia apresentou as duas maiores taxas de vacinação, a primeira, 117%, observada no primeiro semestre de 2020, com taxa de variação semestral de - 8,57% (IC95% - 20,2 a 4,8), e a segunda, 92%, observada no primeiro semestre de 2017, com taxa de variação semestral de – 8,57% (IC95% - 20,2 a 4,8). As tendências de longo prazo das taxas de vacinação foram de estabilidade na maioria dos municípios avaliados. Uma vez que grande parte das taxas foram inferiores a 70% em todos os anos avaliados, essa estabilidade se torna desfavorável. Os resultados nos sugerem pouca evolução no programa de vacinação contra a brucelose bovina no Sudoeste Goiano o que pode influenciar negativamente a prevalência da doença na região.

The conclusion is that with out economic development the nation cannot achieve any goal. Economic development is provide the guide line how the destination and goal of goal can be achieved.
Develop Real-Time Robot Control Architecture Using Robot Operating System and EtherCAT

This paper presents the potential of combining ROS (Robot Operating System), its state-of-art software, and EtherCAT technologies to design real-time robot control architecture for human–robot collaboration. For this, the advantages of an ROS framework here are it is easy to integrate sensors for recognizing human commands and the well-developed communication protocols for data transfer between nodes. We propose a shared memory mechanism to improve the communication between non-real-time ROS nodes and real-time robot control tasks in motion kernel, which is implemented in the ARM development board with a real-time operating system. The jerk-limited trajectory generation approach is implemented in the motion kernel to obtain a fine interpolation of ROS MoveIt planned robot path to motor. EtherCAT technologies with precise multi-axis synchronization performance are used to exchange real-time I/O data between motion kernel and servo drive system. The experimental results show the proposed architecture using ROS and EtherCAT in hard real-time environment is feasible for robot control application. With the proposed architecture, a user can efficiently send commands to a robot to complete tasks or read information from the robot to make decisions, which is helpful to reach the purpose of human–robot collaboration in the future.
Búsqueda de señal orbital en isótopos estables de carbono y oxígeno de belemnites del Jurásico Inferior de la cuenca Vasco-Cantábrica mediante el periodograma suavizado de Lomb-Scargle

Los isótopos estables obtenidos de muestras fosilizadas de macrofósiles, como los belemnites, son unos de los pocos registros geológicos existentes del Jurásico Inferior, por lo cual han sido usados para reconstrucciones de temperaturas y salinidades del océano de esa época. Sin embargo, hasta la fecha no han sido utilizados para averiguar si estos paleoindicadores pudieron registrar algún tipo de evento periódico relacionado con los ciclos orbitales de la Tierra. Por esta razón y teniendo en cuenta varias de las limitaciones al utilizar estos tipos de datos, en este trabajo se presenta un novedoso estudio donde se aplica una técnica avanzada de análisis espectral conocida como el periodograma suavizado de Lomb-Scargle, la cual puede ser aplicada de modo directo a series temporales no equiespaciadas contaminadas por ruido. El objetivo de este trabajo es identificar la presencia de ciclos orbitales que se hayan podido registrar en series temporales de valores medios de δ18O y δ13C provenientes de muestras fosilizadas de belemnites recolectadas en la cuenca Vasco-Cantábrica teniendo en cuenta los errores de datación de estas muestras en la estimación del espectro. De manera especial se hace énfasis en la búsqueda de alguno de los ciclos de la excentricidad, como el de largo periodo localizado ca. 400 Ka o el de menor periodo localizado ca. 100 ka, porque se sabe que el ciclo de 400 Ka ha permanecido invariable desde el Mesozoico hasta el presente y porque ambos ciclos han sido identificados en registros estratigráficos del Mesozoico recolectados en diferentes áreas geográficas. Sin embargo, a pesar de la rigurosidad de nuestros análisis, no se encontró señal orbital de 400 Ka aunque si una localizada cerca de los 109 Ka, la cual podría estar relacionada con los ciclos de corto periodo de la excentricidad de la Tierra.
LEED Scores of Residential Buildings in Poor Cities: Kabul City Case

Urbanization and technology have proven to be detrimental to the environment. Buildings contribute a significant portion of this damage. This issue motivated governments, builders, engineers, and architects to seek ways to reduce buildings’ environmental footprints. Leadership in Energy and Environmental Design (LEED), developed by the U.S. Green Building Council (USGBC), is one of the most widely used strategies to ensure energy efficiency and a clean environment in buildings. In Afghanistan, where there are no active regulatory frameworks for energy saving and efficiency for the building sector, it is imperative to promote the transformation of the building industry and practices towards sustainability. In this regard, the role of the residential building sector is of utmost importance due to its major share in the country’s energy consumption and GHG emissions profile. Thus, this study assesses the energy efficiency and environmental impact of existing buildings in Kabul city concerning the LEED rating system. This research suggests practical steps to improve the sustainability of the residential building stock in Kabul city. Robust sets of data on existing residential buildings in Kabul are collected, classified, evaluated, and compared to LEED standards. This research reveals and concludes that most of the existing buildings in Kabul city are in poor conditions and do not meet the minimum requirements to be a candidate for LEED certification. A detailed analysis of the results has led to recommendations on how these buildings could improve to meet the LEED criteria. This is the first study of its kind conducted for Kabul city residential building. Considering the cross-sectoral nature of the building industry, the findings of this study will contribute to many other areas such as water, transportation, ICT, health, energy and the environment.
Toward a (Re)Integrated Application of Bourdieuan Theory

Bourdieu’s critical analysis of capital (BCAC) is a useful tool for unmasking how schools legitimate class structure and identifying the institutional, societal, and cultural forces that structure class reproduction and oppression. In this paper, we examine the ways educational researchers have constrained the critical application of Bourdieu’s concepts. We highlight the utility of BCAC for exposing the symbolic violence that educational systems enact upon students and families who are unfamiliar with the “culture of power. ” Our purpose is to engage in a revitalized critique against the reproduction of educational inequalities and explicate how BCAC is useful toward these ends.
Scalable and Reliable Data Center Networks by Combining Source Routing and Automatic Labelling

Today, most user services are based on cloud computing, which leverages data center networks (DCNs) to efficiently route its communications. These networks process high volumes of traffic and require exhaustive failure management. Furthermore, expanding these networks is usually costly due to their constraint designs. In this article, we present enhanced Torii (eTorii), an automatic, scalable, reliable and flexible multipath routing protocol that aims to accomplish the demanding requirements of DCNs. We prove that eTorii is, by definition, applicable to a wide range of DCNs or any other type of hierarchical network and able to route with minimum forwarding table size and capable of rerouting around failed links on-the-fly with almost zero cost. A proof of concept of the eTorii protocol has been implemented using the Ryu SDN controller and the Mininet framework. Its evaluation shows that eTorii balances the load and preserves high-bandwidth utilization. Thus, it optimizes the use of DCN resources in comparison to other approaches, such as Equal-Cost Multi-Path (ECMP).
Independent Double-Boost Interleaved Converter with Three-Level Output

This paper introduces a novel converter topology based on an independent controlled double-boost configuration. The structure was achieved by combining two independent classic boost converters connected in parallel at the input and in series at the output. Through proper control of the two boost converters, an interleaved topology was obtained, which presents a low ripple for the input current. Being connected in series at the output, a three-level structure was attained with twice the voltage gain of classic boost and interleaved topologies. A significant feature of the proposed converter is the possibility of independent operation of the two integrated boost converters, in both symmetrical and asymmetrical modes. This feature may be particularly useful in voltage balancing or interconnection with bipolar DC grids/applications. The operation principle, simulations, mathematical analysis, and laboratory prototype experimental results are presented.
Epidemiology and Clinical Characteristics of the First 500 Positive Cases of COVID-19. A Multicenter Retrospective Study across the Najran Region of the Kingdom of Saudi Arabia (KSA)

Introduction: Coronavirus Disease 2019 (COVID-19) is a viral infection that was first reported in Wuhan, China on 31 December 2019. This study aimed to clarify the epidemiology and clinical characteristics of 500 first COVID-19 in the Najran region, Saudi Arabia. Material and Methods: A multi-center retrospective study design was employed to study the first 500 confirmed COVID-19 positive cases in Najran province, Kingdom of Saudi Arabia (KSA). Data were collected from 1 March 2020 until 1 July 2020 and provided by the Infection Prevention and Control (IPC) department from the hospitals. Included cases were confirmed using real-time reverse transcriptase-polymerase chain reaction (RT-PCR). Demographic, vital signs, symptoms, incubation period, travel or exposure history medical history, and comorbidities were collected. Logistic regression analysis was used to explore the association between potential risk factors associated with symptoms occurrence of COVID-19. Results: The median age of 500 COVID-19 patients was 31 years; 333 (66.6%) males. A total of 34 (6.8%) were Healthcare Workers (HCWs). Out of the 500 patients, 180 (36%) had at least one comorbid disease. The most common symptoms on admission were fever 281 (56.2%), cough 266 (53.2%), shortness of breath 166 (33.2%), and malaise 113 (22.6%). Most of the patients presented with mild disease severity 310 (62%). Nationality, age, and Diabetes Miletus (DM) were independently and significantly associated with being symptomatic (P β = 2.968, CI = 2.002 - 4.400, P = 0.0010). For every 1 year increase in age, the risk of being symptomatic increased by 5.8% (β = 1.045, CI = 1.033 - 1.058, P = 0.001). Compared with non-DM patients, DM patients had a 4.05 times higher risk (β = 4.05, CI = 2.188 - 7.507, P = 0.001) of getting symptoms. Conclusions: The study concluded that the majority of the COVID-19 patients were symptomatic or had mild disease severity. Age, nationality, and DM were the important risk factors in being symptomatic.
Looking for a safe haven: tail-anchored proteins and their membrane insertion pathways

Abstract Insertion of membrane proteins into the lipid bilayer is a crucial step during their biosynthesis. Eukaryotic cells face many challenges in directing these proteins to their predestined target membrane. The hydrophobic signal peptide or transmembrane domain (TMD) of the nascent protein must be shielded from the aqueous cytosol and its target membrane identified followed by transport and insertion. Components that evolved to deal with each of these challenging steps range from chaperones to receptors, insertases, and sophisticated translocation complexes. One prominent translocation pathway for most proteins is the signal recognition particle (SRP)-dependent pathway which mediates co-translational translocation of proteins across or into the endoplasmic reticulum (ER) membrane. This textbook example of protein insertion is stretched to its limits when faced with secretory or membrane proteins that lack an amino-terminal signal sequence or TMD. Particularly, a large group of so-called tail-anchored (TA) proteins that harbor a single carboxy-terminal TMD require an alternative, post-translational insertion route into the ER membrane. In this review, we summarize the current research in TA protein insertion with a special focus on plants, address challenges, and highlight future research avenues.
A metabolomic strategy based on integrating headspace gas chromatography-mass spectrometry and liquid chromatography-mass spectrometry to differentiate the five cultivars of Chrysanthemum flower

The extreme complexity of the chemical composition of plant extracts requires an unbiased and comprehensive detection methodology to improve the potential of metabolomic study. The present work, taking five closely related cultivars of Chrysanthemum flowers as a typical case, attempts to develop a metabolomic strategy to find more markers of metabolites for precise differentiation based on headspace gas chromatography-mass spectrometry (HSGC-MS) and ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UHPLC-QTOF/MS). In detail, 53 batches of Chrysanthemum flower samples were collected and analyzed. The fusion of datasets from HSGC-MS and UHPLC-QTOF/MS was done in two different ways. After comparison, the fusion of the total peak area normalized metabolomic data was performed for multivariate statistical analysis. A total of 21 marker compounds (including 14 volatile and 7 nonvolatile metabolites) were identified, and a heatmap was employed for clarifying the distribution of the identified metabolites among the five cultivars. The results indicated that the integrated platform benefited the metabolomic study of medicinal and edible herbs by providing complementary information through fully monitoring functional constituents.
Surgical Approach to Rib Fractures

Rib fractures due to thorax trauma are one of the issues that mostly concern thoracic surgeons. Treatment for rib fractures is usually conservative. However, in some cases, fractured rib can cause complicated situations and surgical repair is required. Very serious respiratory problems occur in multiple costa fractures. Therefore, many advantages of surgical stabilization of the thorax wall have been reported. Especially shortening mechanical ventilation, decreasing the duration of intensive care unit stay, is important in preventing complications. Operation indications; Persistent pain despite intercostal block, narcotic and nonsteroidal anti-inflammatory analgesics, It was determined upon the presence of leakage from the thorax tube, intrathoracic hematoma and flail chest deformity. Nowadays, nithinol plates and titanium plates are frequently used in surgeon fixation of the rib fractures.
