Best Feature Selection for Horizontally Distributed Private Biomedical Data Based on Genetic Algorithms
Authors: Tarik Boudheb , Zakaria Elberrichi
Published: June 2019

Due to the growing success of machine learning in the healthcare domain, medical institutions are striving to share their patients' data in the intention to build more accurate models which will be used to make better decisions. However, due to the privacy of the data, they are reluctant. To build the best models, they have to make the best feature selection for horizontally distributed private biomedical data. The previous proposed solutions are based on data perturbation techniques with the loss of performance. In this article, the researchers propose an original solution without perturbation. This is so the data utility is preserved and therefore the performance. The proposed solution uses a genetic algorithm, a distributed Naïve Bayes classifier, and a trusted third-party. The results obtained by the proposed approach surpass those obtained by other researchers, for the same problem.
Network Coding and Hierarchical Modulation for Energy Efficient Cooperative WBAN
Authors: Waheed Maham , Talha Sadaf , Ahmad Rizwan , Kiani Adnan Khalid , Alam Muhammad Mahtab , Ahmed Waqas
Published: June 2019

Wireless body area networks (WBANs) have revolutionized healthcare by enabling remote supervision, prior detection, and disease interception using invasive and wearable sensor devices. The limited battery capacity of the sensors coupled with the poor channel condition (that may arise from body postures) require cooperative transmission strategies that can prolong the sensors' life time and associated functionalities. Therefore, in this article, a cooperative scheme based on single-stage relaying is presented for spectrum and energy efficiency. The relay operating for two different scenarios, i.e. network coding and hierarchical modulation, is discussed. The general trend for bit error rate (BER) is observed by modeling a Rayleigh faded link catering path loss. The results are further studied for actual channel models, defined in WBAN standard. The effect of hop-length variation on BER and packet error rate (PER) are discussed. Simulation results show that both cooperative schemes outperform direct communication. A hybrid switching scheme is proposed to enhance efficiency.

Published: June 2019

There is a growing producer and consumer interest in medical devices and the commensurate need for regulatory frameworks to ensure the quality of medical devices marketed locally and globally. This work focuses on formalizing the clauses enacted by Regulation (EU) 2017/745 for risk-based classification and class-based conformity assessment regarding marketability of medical devices. The resulting knowledge base (KB) represents clauses in Positional-Slotted Object-Applicative (PSOA) RuleML by integrating F-logic-like frames with Prolog-like relationships for atoms used as facts and in the conclusions and conditions of rules. Rules can apply polyadic functions, define polyadic relations, and augment conclusions with actions and conditions with events. The PSOA RuleML-implemented Medical Devices Rules KB was tested by querying in the open-source Java-implemented PSOATransRun system, which has provided a feedback loop for refinement and extension. This prototype can contribute to the licensing process of stakeholders and the registration of medical devices with a CE conformity mark.

Published: June 2019

l'Inspection Panel della Banca Mondiale è stato il primo meccanismo indipendente (IAM) finalizzato a ricevere denunce da parte di persone che lamentavano un danno derivante dalla potenziale mancanza di sostegno alle politiche e alle procedure delle istituzioni finanziarie internazionali. Dal 1993 il Panel ha trattato denunce riguardanti i progetti della Banca Mondiale su richiesta delle comunità interessate e ha contribuito a porre rimedio ai relativi danni. l'articolo descrive dettagliatamente questi risultati, con particolare riguardo all' "apprendimento istituzionale", soffermandosi inoltre sulla collana Emerging Lessons Series del Panel stesso, una serie di pubblicazioni recenti che riassumono le esperienze derivanti da casi relativi a: reinsediamento involontario, popolazioni indigene, valutazione ambientale, consultazione e divulgazione. l'articolo si conclude con una discussione dei recenti miglioramenti apportati all'attività del Panel, sottolineando il suo ruolo nel promuovere comportamenti responsabili attraverso le procedure operative adottate e il successivo "apprendimento istituzionale".
HEINRICH MEIER E LA SFIDA DELLA TEOLOGIA POLITICA
Authors: Menon Marco
Published: June 2019

Questo articolo offre una breve panoramica dei libri di Heinrich Meier sulla teologia politica di Carl Schmitt, ovvero Carl Schmitt e Leo Strauss, e Die Lehre Carl Schmitts. Questi scritti, pubblicati rispettivamente nel 1988 e nel 1994, e recentemente tradotti in italiano da Cantagalli (Siena), hanno suscitato sia valutazioni entusiastiche che critiche feroci. Il succo dell'interpretazione di Meier è il seguente: il nucleo del pensiero di Schmitt è la sua fede cristiana. La dottrina politica di Schmitt deve essere intesa come teologia politica, cioè come dottrina politica che pretende di essere fondata sulla rivelazione divina. L'atteggiamento fondamentale del teologo politico, quindi, è la pia obbedienza all'insondabile volontà di Dio. L'ipotesi del documento è che la lettura di Meier, che da un punto di vista storico potrebbe apparire come molto controversa, sia essenzialmente il tentativo di articolare l'alternativa fondamentale tra teologia politica e filosofia politica. La presunta stilizzazione di Carl Schmitt e Leo Strauss da parte di Meier è una forma di "platonismo", cioè una purificazione teorica finalizzata a una chiara formulazione di ciò che egli intende per "problema teologico-politico".

Authors: Al Chalabi Rawaa , Salih Shahlaa M. , Saad Sajid , Jawad Hayder
Published: June 2019

Bladder cancer is an abnormal cellular multiplication without control arising from the urinary bladder urothelium. Cells cycle is a strictly controlled process regulated by protein complexes composed of cyclins and cyclin-dependent kinases and also by several tumor suppressor gene protein products acting at the Go/G1 checkpoint of the cell-cycle. This study was designed to evaluate the frequency of p53 and p21 expression as biomarkers to monitor the disease and compare the results with those of others. Seventy-three tumors with different stages and grades were collected from patients with bladder carcinoma and ten normal bladder biopsies from forensic autopsy. Sections were immunohistochemically stained for p53 and p21. Results revealed that p53 positive immune reactivity was observed in (57.5%) which were exclusively nuclear and no immune reactivity detectable in (42.5%) of tumors, while all normal tissues expressed negative patterns. Positive immune staining of p21 was recorded in (69.5%) and negative p21 immune staining was recorded in 22 (31.1%), as well as ten normal urothelium. Statistically p53 and p21 over-expression was significantly related to stage and grade of tumors (P<0.05).
Methodological rigour and coherence in the construction of instruments: The emotional social screening tool for school readiness
Authors: Munnik Erica , Smith Mario R.
Published: June 2019

The need for a contextually relevant and empirically grounded measure of emotional social competence in Grade R children was identified in the literature. The aim of this study was to develop a contextually relevant instrument for emotional social competence in preschool children. The study adopted a four-phase approach with each phase using distinct methodological approaches. This article reports on the use of multiple research methods to achieve methodological rigour and coherence in the construction. Phase 1 used systematic review methodology to establish a theoretical foundation for the instrument. The results identified two domains and nine subdomains that formed the theoretical model for the instrument. In phase 2 stakeholder perceptions of emotional and social competence were identified through concept mapping to increase contextual relevance and sensitivity. The results highlighted that early stimulation and contextual factors impacted school readiness and needed to be included. The construction of the instrument incorporated the findings from the first two stages. The draft instrument was presented to a panel of experts, using the Delphi technique, for validation of content and scalar decisions in phase 3. The results supported the proposed format and content of the screening tool. The resulting instrument was piloted in phase 4 with survey research. Good internal consistency was reported and the factor structure supported. The multiphase methodology provided an overarching framework with methodological rigour and coherence. The grounding in the literature, stakeholder consultation and rigorous validation processes enhanced the resultant instrument. The articulation of one phase into the next ensured methodological coherence.
Histone Deacetylases in Stroke
Authors: Kao Mei-Han , Lin Teng-Nan
Published: June 2019

Stroke is the second leading cause of death and the leading cause of adult disability worldwide. Despite an impressive amount of neuroprotective agents that has been identified in experimental stroke, none of them proved efficient in clinical trials. There is a general consensus that an effective treatment requires the ability to interact with not one, but multiple pathophysiological cascades at different levels that induced by the insult – cocktail therapy. Luckily, recent progress in the field of epigenetics revealed that epigenetic modifications had influence on many known pathways involved in the complex course of ischemic disease development. The fact that epigenetic molecules, by altering transcriptional regulation, may simultaneously act on different levels of ischemic brain injury makes them promising candidates for clinical use. These modifications arise typically owing to deoxyribonucleic acid methylation and histone acetylation. The aim of this review is to give a comprehensive overview of current advances in stroke epigenetics, in particular, the physiological and pathological functions of the 11 classical histone deacetylases.

Most deaths in tuberculous meningitis occur in the early part of the illness. We assessed the determinants of early deaths, occurring within 2 months of intensive therapy. We prospectively included consecutive newly diagnosed adults with HIV-negative tuberculous meningitis. Patients were given WHO-recommended antituberculosis treatment and were followed up for 9 months. We enrolled 152 patients. A total of 26 deaths were recorded during 2 months. The logistic regression analysis revealed that papilledema (P = 0.029, odds ratio (OR) = 4.8 [1.2–19.8]), increasing age (P = 0.001, OR = 1.07 [1.03–1.1]), stage-III disease (Glasgow coma scale score ≤ 10; P = 0.01, OR = 4.2 [1.4–12.3]), and hydrocephalus (P = 0.003, OR = 8.4 [2.1–33.6]) were independently associated with death. In addition, cerebral infarcts (P = 0.012, OR = 5.6 [1.5–21.3]), paraparesis (P = 0.004, OR = 8.8 [2.02–38.1]), and age (P = 0.005, OR = 1.05 [1.02–1.09]) were associated with poor functional outcome. In conclusion, disease severity predicts early deaths in tuberculous meningitis.

Turkey and the US in the Middle East
Authors: Balik Gürcan
Published: June 2019

Written by the former chief foreign policy advisor to the Turkish president and based on unprecedented access to official documents and communiques, this book gives the inside story of Turkish US relations from the first Gulf War, through debates on the Iraqi Kurdish question, the 2003 invasion of Iraq and into the present day. Using events in Iraq as the basis for a theoretical case study, Gurcan Balik argues that Turkey influenced US foreign policy on several key occasions, and that Turkish support was instrumental in the first intervention in Iraq. After Iraq's 1991 uprisings, however, Turkey's interests in the Middle East began to diverge from those of the US, and their relationship gradually deteriorated, evident in Turkey's refusal to open up its northern border to aid the US advance to Baghdad in 2003. Balik contends that an 'Iraq gap' then emerged, which has since had major implications for the Turkish economy and for the future of the Middle East.Turkey and the US in the Middle East contains hitherto unpublished primary source material, and is an essential addition to the scholarship of the period.
Propagation to the upper atmosphere of acoustic-gravity waves from atmospheric fronts in the Moscow region
Authors: Kurdyaeva Yuliya , Kulichkov Sergey , Kshevetskii Sergey , Borchevkina Olga , Golikova Elena
Published: June 2019

Abstract. The paper uses experimental data of pressure variations on the Earth's surface during the passage of an atmospheric front recorded by a network of four microbarographs in the Moscow region. Applying these experimental data, empirical approximations of atmospheric pressure field oscillations are suggested. The obtained approximating surface pressure functions are used as the lower boundary condition for simulating the vertical propagation of acoustic-gravity waves from a source in the lower troposphere. Estimates of the amplitude of temperature disturbances in the upper atmosphere caused by acoustic-gravity waves from a propagating atmospheric front are obtained. For the amplitude of wave temperature disturbances, values of about 200 K are obtained. The amplitude of temperature disturbances in the upper atmosphere caused by background pressure fluctuations on the Earth's surface is estimated at 4–5 K.

Authors: Khatri Punit , Gupta Karunesh Kumar , Gupta Raj Kumar
Published: June 2019

Abstract. This paper proposes the development of a Raspberry Pi-based
hardware platform for drinking-water quality monitoring. The selection of
water quality parameters was made based on guidelines of the Central
Pollution and Control Board (CPCB), New Delhi, India. A graphical user interface
(GUI) was developed for providing an interactive human machine interface to
the end user for ease of operation. The Python programming language was used for
GUI development, data acquisition, and data analysis. Fuzzy computing
techniques were employed for decision-making to categorize the water quality
in different classes like “bad”, “poor”, “satisfactory”, “good”, and
“excellent”. The system has been tested for various water samples from eight
different locations, and the water quality was observed as being good,
satisfactory, and poor for the measured water samples. Finally, the
obtained results were compared with the benchmark for authentication.
Terrestrial Water Loss at Night: Global Relevance from Observations and Climate Models
Authors: Padrón Ryan S. , Gudmundsson Lukas , Michel Dominik , Seneviratne Sonia I.
Published: June 2019

Abstract. Nocturnal water loss (NWL) from the surface into the atmosphere is often overlooked because of the absence of solar radiation to drive evapotranspiration and the measuring difficulties involved. However, there is growing evidence that suggests NWL – and particularly nocturnal transpiration – represents a considerable fraction of the daily values. Here we provide a global overview of the characteristics of NWL based on latent heat flux estimates from the FLUXNET2015 dataset, as well as from simulations of global climate models. Eddy-covariance measurements at 99 sites indicate that on average NWL represents 6.3 % of total evapotranspiration. There are six sites where NWL is higher than 15 %; these are mountain forests with considerable NWL during winter related to snowy and windy conditions. Higher vapor pressure deficit, wind speed and soil moisture are related to higher NWL, although this is not consistent across all sites. On the other hand, the global multi-model mean of terrestrial NWL is 7.9 % of total evapotranspiration. The spread of the model ensemble, however, is greater than 20 % over 70 % of the land area. Finally, the multi-model mean of future projections indicates an increase of NWL everywhere by an average of 1.8 %, but the spread between models at individual locations is often twice as large at least. Overall, this study highlights the relevance of water loss during the night and opens the door to explore its influence on the water cycle and the climate system under present and future conditions.

Published: June 2019

Abstract. According to the burmester theory, an infinite number of spherical or planar 4R linkages for a specific four-orientation task can be synthesized, but most of the linkage solutions calculated by this method are invalid because of motion defect, poor performance and others. In order to improve the synthesis efficiency, a program package based on Matlab is developed to find a satisfied linkage solution automatically and quickly. Firstly, the calculation on circle points and the center points based on the burmester theory in spherical problems is introduced. Secondly, the calculation methods of linkage defect discrimination, linkage type classification, linkage performance evaluation and solutions visualization based on the theory of spherical trigonometry are presented respectively. Thirdly, the synthesis calculation of program package is extended to the planar 4R linkage based on the theory of planar analytic geometry. Finally, the examples of the spherical synthesis problem and the planar synthesis problem based on solutions map are introduced to test the program package, the result proves this program package is effective and flexible.
Processes culminating in the 2015 phreatic explosion at Lascar
volcano, Chile, monitored by multiparametric data

Published: June 2019

Abstract. Small steam-driven volcanic explosions are common at volcanoes worldwide but are rarely documented or monitored; therefore, these events still put residents and tourists at risk every year. Steam-driven explosions also occur frequently (once every 2–5 years on average) at Lascar volcano, Chile, where they are often spontaneous and lack any identifiable precursor activity. Here, for the first time at Lascar, we describe the processes culminating in such a sudden volcanic explosion that occurred on October 30, 2015, which was thoroughly monitored by cameras, a seismic network, and gas (SO2 and CO2) and temperature sensors. Prior to the eruption, we retrospectively identified unrest manifesting as a gradual increase in the number of long-period (LP) seismic events in 2014, indicating an augmented level of activity at the volcano. Additionally, SO2 flux and thermal anomalies were detected before the eruption. Then, our weather station reported a precipitation event, followed by changes in the brightness of the permanent volcanic plume and (10 days later) by the sudden volcanic explosion. The multidisciplinary data exhibited short-term variations associated with the explosion, including (1) an abrupt eruption onset that was seismically identified in the 1–10 Hz frequency band, (2) the detection of a 1.7 km high white-grey eruption column in camera images, and (3) a pronounced spike in sulfur dioxide (SO2) emission rates reaching 55 kg sec−1 during the main pulse of the eruption as measured by a mini-DOAS scanner. Continuous CO2 gas and temperature measurements conducted at a fumarole on the southern rim of the Lascar crater revealed a pronounced change in the trend of the relationship between the carbon dioxide (CO2) mixing ratio and the gas outlet temperature; we believe that this change was associated with the prior precipitation event. An increased thermal anomaly inside the active crater observed through Sentinel-2 images and drone overflights performed after the steam-driven explosion revealed the presence of a fracture ~ 50 metres in diameter truncating the dome and located deep inside the active crater, which coincides well with the location of the thermal anomaly. Altogether, these observations lead us to infer that a lava dome was present and subjected to cooling and inhibited degassing. We conjecture that a precipitation event led to the short-term build-up of pressure inside the shallow dome that eventually triggered a vent-clearing phreatic explosion. This study shows the chronology of events culminating in a steam-driven explosion but also demonstrates that phreatic explosions are difficult to forecast, even if the volcano is thoroughly monitored; these findings also emphasize why ascending to the summits of Lascar and similar volcanoes is hazardous, particularly after considerable rainfall.
ER3D: a structural and geophysical 3-D model of central Emilia-Romagna (northern Italy) for numerical simulation of earthquake ground motion
Authors: Klin Peter , Laurenzano Giovanna , Romano Maria Adelaide , Priolo Enrico , Martelli Luca
Published: June 2019

Abstract. During the
2012 seismic sequence of the Emilia region (northern Italy),
the earthquake ground motion in the epicentral area featured longer duration and higher velocity
than those estimated by empirical-based prediction equations typically adopted in Italy.
In order to explain these anomalies, we
(1) build up a structural and geophysical 3-D digital model of the crustal sector
involved in the sequence,
(2) reproduce the earthquake ground motion at some seismological stations through
physics-based numerical simulations and
(3) compare the observed recordings with the simulated ones.
In this way, we investigate how the earthquake ground motion in the epicentral area is
influenced by local stratigraphy and geological structure buried under the Po Plain alluvium.
Our study area covers approximately 5000 km2 and extends from the right Po River bank to the
Northern Apennine morphological margin in the N–S direction, and between the two chief towns of
Reggio Emilia and Ferrara in the W–E direction, involving a crustal volume of 20 km thickness.
We set up the 3-D model by using already-published geological and geophysical data,
with details corresponding to a map at scale of 1:250 000.
The model depicts the stratigraphic and tectonic relationships of the main geological formations,
the known faults and the spatial pattern of the seismic properties.
Being a digital vector structure, the 3-D model can be easily modified or refined locally
for future improvements or applications.
We exploit high-performance computing to perform numerical simulations
of the seismic wave propagation in the frequency range up to 2 Hz.
In order to get rid of the finite source effects and validate the model response,
we choose to reproduce the ground motion related to two moderate-size aftershocks of the
2012 Emilia sequence that were recorded by a large number of stations.
The obtained solutions compare very well to the recordings available at about 30 stations
in terms of peak ground velocity and signal duration. Snapshots of the simulated wavefield
allow us to attribute the exceptional length of the observed ground motion
to surface wave overtones that are excited in the alluvial basin
by the buried ridge of the Mirandola anticline.
Physics-based simulations using realistic 3-D geomodels show eventually to be
effective for assessing the local seismic response and the seismic hazard in
geologically complex areas.
West Greenland ice sheet retreat history reveals elevated
precipitation during the Holocene thermal maximum
Authors: Downs Jacob , Johnson Jesse , Briner Jason , Young Nicolás , Lesnek Alia , Cuzzone Josh
Published: June 2019

Abstract. We investigate changing precipitation patterns in the Kangerlussuaq region of west central Greenland during the Holocene thermal maximum, using a new chronology of ice sheet terminus position through the Holocene and a novel inverse modeling approach based on the unscented transform (UT). The UT is applied to estimate changes in annual precipitation in order to reduce the misfit between modeled and observed terminus positions. We demonstrate the effectiveness of the UT for time-dependent data assimilation, highlighting its low computational cost and trivial parallel implementation. Our results indicate that Holocene warming coincided with elevated precipitation, without which modeled retreat in the Kangerlussuaq region is more rapid than suggested by observations. Less conclusive is if high temperatures during the HTM were specifically associated with a transient increase in precipitation, as the results depend on the assumed temperature history. The importance of precipitation in controlling ice sheet extent during the Holocene underscores the importance of Arctic sea ice loss and changing precipitation patterns on the future stability of the GrIS.

"Satis amplam libertatem": una interpretación sobre el Tratado Político de Spinoza
Authors: Tejeda Gómez Cristian Andrés , Sobarzo Morales Mario Patricio
Published: June 2019

Dentro de la obra madura de Spinoza, la Ética y el Tratado Teológico-Político (TTP) se han analizado ampliamente. Sin embargo, el Tratado Político (TP) ha sido menormente estudiado por ser una obra inconclusa y con problemas estructurales. Nosotros afirmamos que la teoría política más acabada de Spinoza se encuentra en el TP. En esta obra se sacan todas las consecuencias de guiarse por una noción estrictamente inmanente de la política. En ese sentido, el TP sigue de manera más coherente el programa trazado por la doctrina fundamental de Spinoza expuesta en la Ética, y no el TTP. Esto nos lleva a la consideración de la política como tendencia en dos direcciones opuestas: ampliación de poder y concentración de poder.

Colonialism and the Agikuyu Women Indigenous Knowledge Systems on Food Crop Production in Kiambu Kenya 1902-1918
Authors: Muraya Martha Wanjiru , Gathungu Geofrey Kingori , Kinyua Lazarus Ngari
Published: June 2019

The introduction colonial capitalist economic policies and practices such as land alienation, forced labour and commercial crop production acted as a major catalyst of change on the existing African indigenous subsistence production especially the Agikuyu Women’s Indigenous Knowledge System (AWIKS). This research paper focused on examining the effects of European colonialism on the AWIKS on food crop production from 1902-1918. The study employed descriptive research design and historical trend analysis and it was done in three sub-counties of Kiambu West, namely, Limuru, Lari and Kikuyu. Purposive and snowballing technique was used to get the respondents who were the bearers of the most relevant information. The main source of information was the corroboration of oral interviews, archival records analysis and secondary data. Oral interviews data were analyzed using Statistical Package for Social Scientists (SPSS) and reported using basic simple descriptive statistics. The Women and Development (WAD) theory helped to examine the nature in which the Agikuyu women were integrated in colonial capitalist economy, which explains their marginalization, subordination, oppression and dependency on men. The study found out that during the establishment of colonial rule the Agikuyu people were moved from their indigenous land and were pushed to poor, marginal and unproductive reserve areas where they did not have enough experience and accumulated indigenous knowledge system of the new agro-ecosystem. In addition, most of the drought tolerant food crops were neglected and others destroyed a move that may have led to underutilization of AWIKS on food crop production. This implied that the food supply was compromised and the society became more vulnerable to drought and famine. Therefore, in order to enhance food supply in the households some of the AWIKS on food crop production may be integrated into the modern western agricultural production practices.

Authors: Mele Marco , Nicolai Floriana
Published: June 2019

The purpose of this paper is to analyze the changes in the functions of the International Monetary Fund after the 2008 financial crisis. Following an extensive introduction concerning the subject of the study and which covers part of the economic literature, the focus was on governance reform and surveillance in the foreign exchange market. Finally, the empirical analysis was carried out concerning the manipulation of exchange rates in a period ranging from 2008-2016 and 15 countries (Taiwan, South Korea, Israel, China, Thailand, Macao, Switzerland, Hong Kong, Singapore, Norway, Qatar, United Arab Emirates, Kuwait, Trinidad and Tobago and Saudi Arabia) that in the period considered massively intervened in the foreign exchange market, keeping their respective currencies undervalued and acquiring an unfair competitive advantage to the detriment of partner economies. The results would tend to confirm that the manipulation of the exchange rate is a persistent and lasting element of the currency policies of the new millennium, highlighting an active insufficiency of the IMF’s action in the exercise of the oversight function on the currency policies of the Members.

Data is the fastest growing asset in the 21st century, extracting insights is becoming of the essence as the traditional ecosystems are incapable to process the resulting amounts, complying with different structural levels, and is rapidly produced. Along this paradigm, the need for processing mostly real time data among other factors highlights the need for optimized Job Scheduling Algorithms, which is the interest of this paper. It is one of the most important aspects to guarantee an efficient processing ecosystem with minimal execution time, while exploiting the available resources taking into consideration granting all the users a fair share of the dedicated resources. Through this work, we lay some needed background on the Hadoop MapReduce framework. We run a comparative analysis on different algorithms that are classified on different criteria. The light is shed on different classifications: Cluster Environment, Job Allocation Strategy, Optimization Strategy, and Metrics of Quality. We, also, construct use cases to showcase the characteristics of selected Job Scheduling Algorithms, then we present a comparative display featuring the details for the use cases.

Mediante um cenário de competitividade crescente, a busca por inovação e melhores resultados financeiros e operacionais tem se tornado fonte de sobrevivência para as empresas no mercado atual. Dessa forma, é importante que as organizações tenham de forma muito clara a estratégia e os caminhos que serão percorridos na busca do sucesso e consolidação no mercado. Apesar de muitas organizações possuírem estratégias definidas e objetivos traçados, muitas ainda pecam no desdobramento desses objetivos em metas mensuráveis para suas equipes, ou até no monitoramento e avaliação dessas metas para acompanhar o quão perto ou o quão longe estão daquilo que fora planejado para a organização. Nesse sentido, esse artigo apresenta um estudo de caso da implementação de uma rotina de monitoramento de indicadores de desempenho como base para a tomada de decisão mais assertiva e direcionada aos objetivos centrais da empresa. Os resultados mostram que a implementação de uma rotina de monitoramento de resultados aplicada como base para a tomada de decisão, desde o nível operacional até o estratégico, auxilia muito na integração das áreas e na busca da causa raiz dos problemas, tendo como alicerce as atividades do ciclo PDCA.

O objetivo do estudo é avaliar a qualidade de serviço utilizando 4 P’s, e o método AHP, para a obtenção da melhor alternativa para uma construtora, localizada na região central do Rio Grande do Sul. Diante a isso, empregouse os 4 P’s (Perfil, Processo, Procedimento, Pessoas), buscando priorizar as variáveis em estudo, mediante a percepção do gestor de uma empresa de construção civil, caracterizando-se um estudo de caso. Os resultados relataram o critério que possui maior grau de importância para a empresa em estudo. Alcançou (60,13%), o critério Pessoas e a alternativa que melhor contribui para o objetivo global foi a “A” que se refere a criação de um ambiente favorável atingindo (54,70%). Assim, o ambiente empresarial está cada vez mais intransigente com as organizações, exigindo que, estas se adaptem às necessidades das pessoas de forma integrada, principalmente quando se trata dos funcionários. Dessa forma, a empresa pode se utilizar das estratégias dos P’s priorizados, investindo nas pessoas para melhorar a qualidade dos serviços prestados. Portanto, o resultado encontrado é elemento importante, para incentivar os funcionários a participarem de treinamentos para tornarem-se ainda, melhores profissionais em suas atividades

Os bancos são caracterizados pelo forte envolvimento entre seus funcionários e clientes. Uma vez que apresentam produtos similares aos concorrentes, as instituições bancárias devem apresentar um diferencial que consiga manter seus clientes e conquistar novos indivíduos. Baseando-se neste fato, o presente artigo busca realizar uma análise entre os fatores qualidade em serviços, valor percebido, imagem corporativa, satisfação e lealdade dos clientes, avaliando como estas se inter-relacionam em um contexto bancário. Para a obtenção dos dados foi aplicada uma survey com uso de questionários em universitários de cursos de graduação da Universidade Federal de São Carlos - campus Sorocaba, sendo os dados analisados pelo método de regressão linear simples e múltipla. Os resultados apontam que a qualidade em serviços e a imagem corporativa influenciam positivamente o valor percebido, explicando 61% da sua variação; a qualidade em serviços, a imagem corporativa e o valor percebido influenciam positivamente a satisfação, explicando 65% da sua variação; a qualidade em serviços influencia positivamente a imagem corporativa, explicando 56% da sua variação; e a satisfação e a imagem corporativa influenciam positivamente a lealdade, explicando 65% da sua variação, sendo que o valor percebido e a qualidade em serviços a influenciam de forma indireta, não podendo ser desprezados. Por meio desses resultados é possível auxiliar os bancos na obtenção de insights, permitindo que haja elaboração de ações estratégicas que possibilitem implantar melhorias nos serviços de forma mais assertiva e eficiente.
Model Checking Based Approach for Compliance Checking

Process mining is the set of techniques to retrieve a process model starting from available logging data. The discovered process model has to be analyzed to verify it respects the defined properties, i.e., the so-called compliance checking. Our aim is to use a model checking based approach to verify compliance. First, we propose an integrated-tool approach using existing tools as ProM (a framework supporting process mining techniques) and CADP (a formal verification environment). More precisely, the execution traces from a software system are extracted. Then, using the “Mine Transition System” plugin in ProM, we obtain a labelled transition system, that can be easily used to verify formal properties trough CADP. However, this choice presents the “state explosion” problem, i.e., models discovered through the classical process mining techniques tend to be large and complex. In order to solve this problem, another custom-made approach is shown, which accomplishes a pre- processing on the traces to obtain abstract traces, where abstraction is based on the set of temporal logic formulae specifying the system properties. Then, from the set of abstracted traces, we discover a system described in Lotos, a process algebra specification language; in this way we do not build an operational model for the system, but we produce only a language description from which a model checking environment will automatically obtain the reduced corresponding transition system. Real systems have been used as case studies to evaluate the proposed methodologies.

Published: June 2019

In this paper, we present the results of the extensive computational experiments with the hybrid genetic algorithm (HGA) for solving the grey pattern quadratic assignment problem (GP-QAP). The experiments are on the basis of the component-based methodology where the important algorithmic ingredients (features) of HGA are chosen and carefully examined. The following components were investigated: initial population, selection of parents, crossover procedures, number of offspring per generation, local improvement, replacement of population, population restart). The obtained results of the conducted experiments demonstrate how the methodical redesign (reconfiguration) of particular components improves the overall performance of the hybrid genetic algorithm.

Published: June 2019

In this study the lifecycle primary energy and greenhouse gas (GHG) implications of multi-storeybuilding versions with different structural frame materials as well as construction systems are analysedconsidering flows from the production, operation and end-of-life phases and the full natural resourceschains. The analysed building versions include conventional and modern construction systems withlight-frame timber, reinforced concrete-frame, massive timber frame, beam-and-column timber frameor modular timber frame structural systems and are designed to the energy efficiency level of thepassive house criteria. The results show that the lifecycle primary energy use and GHG emissions forthe reinforced concrete building system are higher than those for the timber-based building systems,due primarily to the lower production primary energy use and GHG emissions as well as greater amountof biomass residues when using wood-based materials. The operation primary energy use and GHGemission for the buildings are lower when heated with cogenerated district heating compared to whenheated with electric-based heat pump, showing the significance of heat supply choice. The findingsemphasize the importance of structural frame material choice and system-wide lifecycle perspective inreducing primary energy use and GHG emissions in the built environment.
