MULTI-SOURCE APPROACHES FOR COMPLEX ARCHITECTURE DOCUMENTATION: THE “PALAZZO DUCALE” IN GUBBIO (PERUGIA, ITALY)
Authors: Patrucco G. , Rinaudo F. , Spreafico A.
Published: May 2019

Abstract. Nowadays, the employment of rapid mapping solutions for architectural survey is more and more considered, not only for the strong reduction of the primary data acquisition times, but also thanks to their adaptability to various contexts, especially in the framework of Cultural Heritage documentation where tailored solutions are required. The combined use of Mobile Mapping Systems (MMS), Unmanned Aerial Vehicles (UAV) for close range aerial image acquisition, and Terrestrial Laser Scanning (TLS) seems to be an effective solution for the architectonic scale compliant to the level of detail and accuracy of 1 : 200, and 1 : 100 scales. The present research tries to evaluate the use of a handheld MMS, the ZEB-Revo RT by Geoslam, an UAV, the DJI Mavic Pro, and a LiDAR system, the Faro Focus3D S 120 by CAM2. The complex case of the documentation metric survey of Palazzo Ducale in Gubbio, the Montefeltro’s Palace, now hosting the museum of itself, allows the comparison of the effectiveness of the used technologies.
Extended Mean - Variance Portfolio Optimization Model: A Comparative Study Among Swarm Intelligence Algorithms
Authors: Jena R. K.
Published: May 2019

Portfolio optimization is one of the important issues in the effective management of investment. There is plenty of research in the literature addressing these issues. Markowitz’s primary portfolio selection model is a more suitable method to solve the model for obtaining fairly optimum portfolios. But, the problem of portfolio optimization is multi-objective in nature that aims at simultaneously maximizing the expected return of the portfolio and minimizing portfolio risk. The computational complexity increases with an increase in the total number of available assets. Therefore heuristic methods are more suitable for portfolio optimization in compare to deterministic methods. This research compares three well-known swarm intelligence algorithms (e.g. Ant Colony Optimization (ACO), Particle Swarm Optimization (PSO) and Artificial Bee Colony (ABC)) for portfolio optimization. The Sharpe ratio was used as one of the important criteria for this comparison. PSO outperformed other algorithms in portfolio optimization experiments. The results were also showed that the portfolios which were made of monthly data had performed better than the yearly data.

Authors: Abilio Ramon , Garcia Cristiano Mesquita , Morais Flavio Lopes de , Neto Antônio Elizeu da Rocha
Published: May 2019

In corporate environments, we can find various information systems (IS), which need to communicate to each other to share and maintain data consistency. Academic environments (AE) are even more complex than corporate environments because they have several IS to help manage different aspects, such as restaurant and library, which need to have consistent data to work properly. Therefore, it is necessary to encounter a form to develop an integration among them and share common, trustworthy data. We present a case study on SOA-based architecture for IS integration within AE to keep data consistent through the systems, to monitor the communication, and to make the integration safe and manageable. We applied the proposal, and the results show that we can integrate, monitor, and manage different software systems and network services and permissions. The main contribution is a useful integration architecture for AE that must share trustworthy data among several, heterogeneous IS and network systems. In addition, a small team can implement and maintain this proposed architecture.

Published: May 2019

Um dos grandes desafios da agricultura é o uso racional de agrotóxicos na prevenção e proteção das culturas contra doenças e pragas, a fim de evitar a aplicação demasiada de agentes químicos nas lavouras, evitando-se danos ao meio ambiente e a saúde humana. Atualmente, as técnicas utilizadas para avaliação da qualidade de pulverização se baseiam na análise do tamanho das gotas que são aplicadas através de etiquetas hidrossensíveis. Neste trabalho foi desenvolvida uma bancada de testes, que permite a simulação do funcionamento de pontas de pulverização, e um sistema de aquisição, condicionamento e análise de dados para realização de um estudo de sensoriamento laser aplicado na identificação de espectros de gotas. Além disso, foi proposto e avaliado um método de classificação baseado em Transformada Rápida de Fourier e Redes Neurais Artificiais. A metodologia utilizada para a avaliação da técnica proposta consiste na aquisição e análise de um sinal de luz proveniente de um raio laser interceptado por um spray de água criado pela ponta, e classificação do padrão com base nas amplitudes do espectro de frequências, obtidos a partir da Transformada Discreta de Fourier do sinal. Para a classificação, foi utilizada uma RNA do tipo Perceptron de Múltiplas Camadas a fim de identificar dois diferentes padrões de pulverização, classificando os espectros de gotas em duas classes, névoa ou jato. Foi feita a validação cruzada e a técnica proposta apresentou 91\% de acurácia. Assim, foi possível concluir que através do método proposto é possível identificar diferentes espectros de gotas.
Probabilistic logic reasoning for subjective interestingness analysis
Authors: Da Rocha José Carlos Ferreira , Guimarães Alaine M. , Estevam Jr. Valter L.
Published: May 2019

This paper presents an approach that uses probabilistic logic reasoning to compute subjective interestingness scores for classification rules. In the proposed approach, domain knowledge is represented as a probabilistic logic program that encodes information from experts and statistical reports. The computation of interestingness scores is performed by a procedure that applies linear programming to reasoning regarding the probabilities of interest. It provides a mechanism to calculate probability-based subjective interestingness scores. Further, a sample application illustrates the use of the described approach.

O crescente aumento do volume de dados, juntamente com a alta complexidade destes, tem gerado a necessidade de se desenvolver técnicas de extração de conhecimento cada vez mais eficientes, tanto em custo computacional quanto em precisão. A maioria dos problemas que são tratados por esses técnicas tem informações complexas a serem identificadas. Para isso são utilizados métodos de aprendizado de máquina, onde esses métodos usam uma variedade de funções dentro das diferentes etapas que são empregadas em suas arquiteturas. Uma dessas consiste no uso de funções de agregação para redimensionar imagens. Neste contexto, apresenta-se um estudo de funções de agregação baseadas na integral de Choquet, onde a principal característica da integral do Choquet, em comparação com outras funções de agregação, reside no fato de que ela considera, por meio da medida fuzzy, a interação entre os elementos a serem agregados. Logo, apresenta-se um estudo avaliativo do desempenho das funções integral de Choquet clássica, integral de Choquet baseada em Cópula em relação as funções máximo e média, procurando resultados que podem ser melhores do que as funções de agregação usualmente aplicadas. Os resultados de tais comparações são promissores, quando avaliados através de medidas de qualidade de imagem.
The Hawking Temperature Intensive Crisis and a Possible Solution that Leads to an Intensive Schwarzschild Surface Temperature
Authors: Haug Espen Gaarder
Published: May 2019

Crothers and Robitaille have recently pointed out that the Hawking temperature and the Unruh temperature are not intensive and how this is inconsistent with thermodynamics, which suggests that the theory around the temperature of black holes is flawed, incomplete, or at least not fully understood. Here we offer a modified Newtonian type acceleration field linked to the Planck scale that leads to a new modified intensive Schwarzschild surface temperature for so-called black holes.
Geotechnical Investigation for Foundation Design at the West Bank of Light House Creek, Lagos Deep Offshore Logistics Free Zone, Nigeria
Authors: H. O. Nwankwoala
Published: May 2019

This study is aimed at investigation for foundation designs at the West Bank Creek, Lagos deep offshore. All field tests were conducted in accordance with standard geotechnical procedure. The soil profiles obtained within the depth explored at the site consist essentially of two soil zones. They are very soft silty clays and medium dense sands. Results revealed that within the depths bored, a relatively high deposit of clay overlies the boreholes from the river-bed to average depth of 3.0 m. In BHs 8, 10, 11 and 12, the clay extends beyond 3.0m thickness with varying depths ranging from 5.0 m to 8.0 m. However, prevalent deposits of sand underlie the clay to the end of the boreholes. In BHs 6 and 9, the entire holes are characterized by huge deposits of sand formation. Notably, the sandy formation exhibited appreciable Standard Penetration Test (SPT) blows indicating sands of medium densification. Based on the field investigations and comprehensive studies, the estimated volume of available sand fill material is 691,863 m3. Sand volume estimate was limited to -10.50 m from the river-bed. All the boreholes have potentials for sand borrows. Scooping of the clayey materials is required to expose the sand deposits. Dredging operation with appropriate dredger should be limited to the area covered by the survey.
Toxic Effects of Domoic Acid on Caenorhabditis elegans and the Underlying Mechanism
Authors: Tian Dongmei , Zhang Ganlan
Published: May 2019

Domoic acid (DA) is a well-known marine bio-toxin and has been investigated extensively through many in vitro and in vivo studies. However, the mechanism for DA-induced toxicity is still not fully understood. In the present study, we performed toxicity assessment of DA in Caenorhabditis elegans system and investigated the underlying mechanism for DA-induced toxicity. Our data show that DA exposure has toxic effects on locomotion behavior, lifespan and intestine of nematodes. Moreover, we observed the increased reactive oxygen species (ROS) formation in DA exposed nematodes, implying the involvement of oxidative stress in DA-induced toxicity. In addition, our data demonstrates that p38 signaling pathway is required for the DA-induced ROS formation and toxicity. Therefore, our study proves the effectiveness of C. elegans system in toxicity assessment of DA, and DA may induce toxicity through p38 pathway dependent oxidative stress.
Quantitative Phenomics of Growth and Size in Animals
Authors: Stass V. L.
Published: May 2019

This study introduces a model of the growth phenotype dynamic in pigs by applying analytical methods. The model describes a transformation of the growth phenotype from 30kg live weight up to the species maximum weight.

This paper focuses on a description of the determinants, which channel growth dynamic through animals' ontogeny. Theoretical notions about the growth are explicitly included in the concept. In the model, functional relations between relevant traits obtained in the experiments and field observations are analysed. Two focal variables, a feed conversion coefficient, and an invariant of growth are explicitly integrated in the model.

The novelty of the research is a proposition that deterministic, analytical model is a conceivable approach to studying a phenotype of a quantitative trait. According to this proposition, processes that contribute to the growth and development continue in later life till a species maximum weight is attained. The concept is formulated as a deterministic, hybrid model. In the model, both standard continuum methods and discrete-time difference equations have been used.

Applied to experimental data, the model has produced a new insight into the problem. In domestic pigs, the following three sets of ontogenetic growth phenotypes have been identified: one set with three species maximum weight phenotypes, one set with three rapid growth phenotypes, and one set with individual maximum weight phenotypes. In the study, not only the sets of growth phenotype are identified but also a possible interpretation of a conversion mode of the sets in ontogeny as well as a reading of growth trajectory dynamic are discussed.

Published: May 2019

The aim was to evaluate the initial development of maize plants when submitted to mineral fertilization with magnesium sources in the presence or absence of seed inoculation with Azospirillum brasilense. To do so, was conducted an experiment in greenhouse. In the essay was adopted a randomized blocks design, in a factorial scheme 3 × 2, represented by the magnesium sources: magnesium sulfate (MgSO4), magnesium oxide (MgO) and control without Mg fertilization, in the presence or absence of inoculation with A. brasilense. The Mg sources were supplied with a dose of 30 kg ha-1, being homogenized in the substrate before sowing the crop. The analysis were carried out in the V4 stage, evaluating: basal stem diameter (BSD); relative chlorophyll content (SPAD index), leaf dry mass (LDM), stem + sheath blade dry mass (SSDM) and root dry mass (RDM). No differences were observed for the factors interaction and for the Mg sources. When considered the seed inoculation there was increases of 7.1%; 6.61%; 19.23%; 28.32%; and 15.17 %, for basal stem diameter, SPAD index, leaf dry mass, stem + sheath blade dry mass and roots, respectively. The inoculation of maize seeds with A. brasilense increases the initial development of maize plants and the SPAD index in greenhouse conditions in the V4, while the fertilization with the magnesium sources do not interfere in the maize development.

This study aimed to verify the effect of the herbicides in the secondary growth control, productivity, and quality in garlic. The treatments were 5 herbicides: Glyphosate; Etoxissulfurom; 2-nicotinic acid; Halossulfurom and Metsulfurom-methyl and 5 doses (0; 10; 15; 20 and 25% of the smallest dose recommended for control of the weed). The experimental design was a randomized block, with 3 repetitions. The following evaluations were made: the total and marketable yield of bulbs, a percentage of secondary growth in bulbs, the medium mass of commercial bulbs and the number of bulbils per bulb of the commercial production. Larger productivities total and marketable was observed for the herbicide Glyphosate, 13.93 t ha-1, and 13.16 t ha-1, with doses of 10.81% and 13.12% of the commercial dose, respectively. The smallest incidence of secondary growth 4.05% was observed for Glyphosate with 15.58% of the dose. The largest medium mass of commercial bulbs 35.75 g were observed for the herbicide Glyphosate with 15.83% of the dose. The herbicides 2-nicotínic acid and Metsulfurom-methyl reduced the total productivity in relation to the control treatment without herbicide application and they promoted little gain in commercial productivity. Some herbicides can control the secondary growth in vernalized garlic, however, are necessary appropriate doses applied 50 days after the planting.

Published: May 2019

The subject of this research proposal concerns the gender representations of women in the border town of Goumenissa, a regional unit of Kilkis in Greece, as these representations are constructed on their speech. Goumenissa has been a meeting place of different origin communities, such as local, Pontiac and east Rumelia populations, after the Turco-Greek exchange of populations in Greek national history during the 1920s.The aim of this on-site research is to investigate and map out the status of the refugee and local women of Goumenissa, in years of turbulence and intensity. The research questions concern three basic thematic units: House working - Working outside, the house - Education/family constraints. What is their insight into family relationships, tradition, education and participation in production? How did they define themselves and were defined by others throughout the historical and social conditions? What kind of imprints did these conditions leave on them? How do they continue today? This on-site historical research was based on individual or group interviews and on professional filmmaking in the area of Goumenissa by the two educators Kiouzepi & Kavallari. The outcome-deliverable has been a historical documentary based on the primary original material coming from the women’s interviews that could be used as a multimodal material within an interdisciplinary approach in teaching social subjects. The theoretical axes of the research are the history of gaze, the cultural studies, the socio-semiotics and the expansion of sources in the local and oral historiography.

LASER WELDING OF DENTAL ALLOYS: A SYSTEMATIC OVERVIEW
Authors: Varghese Shanti , Bhat Vinaya , Joseph Suja
Published: May 2019

Aim: The objective of this article is to review information on laser welding of dental alloys. Its rationale, design, advantages, and disadvantages have been reviewed and compared with the conventional techniques of joining dental alloys. Its effects on the commonly used dental alloys and its associated welding defects have also been discussed.Materials and Methods: A broad search of the published literature was performed using Medline and pub med from 1960 to 2012. The key words used for the search were ‘laser welding’, ‘dental alloys’, ‘laser parameters’, ‘welding principle’ and ‘welding procedure’. It was observed that much of the research work was done from the year 2000 onwards. A hand search of textbooks, relevant articles, and manufacturers’ literature was also conducted.Results: Within the limitations of the information obtained and systematically reviewed, it can be inferred that laser beam welding definitely outwits the conventional procedures of joining dental alloys. High precision, accuracy and productivity, reduced distortion, high mechanical strength of the weld joint, corrosion resistant weld joint are a few advantages of laser beam welding technique. The main drawback of laser welding includes its high investment, operating and maintenance costs. To overcome the minor drawbacks of laser welding, TIG welding has been introduced. It involves reduced investment costs, very compact dimensions, low weight, maintenance free and low operating costs.Conclusion: A number of techniques are available for joining dental alloys; each having its own pros and cons. Laser welding still remains the recommended technique due to its precision and accuracy. Continuing research and development are resulting in newer technologies that can overcome the drawbacks of previous techniques. This will provide clinicians and technicians more options in the realm of adequate training and operator expertise.

Diterpenoid alkaloids from Aconitum and Delphinum species
Authors: D Batsuren , N Batbayar , J Tunsag
Published: May 2019

Since 1986 we started investigating diterpene alkaloids from Aconitum and Delphinum species in Mongolia. Alkaloid composition of some 12 species of Aconitum and Delphinum of Ranunculaceae family and 63 individual compounds were isolated and identified. Among them 9 were newly found naturally-occurring compounds and structure of these alkaloids were elucidated completely. High resolution Mass-spectrometry, 1H and 13C NMR, 2D NMR techniques such as COSY, HMQC, HMBC were employed to elucidate structure of new compounds. Structure of altaconitine was elucidated and confirmed by applying X-ray crystallographic analysis in addition to above- mentioned techniques. As a result of our long-term chemical in-vestigation of plant species of Mongolia, we have observed and established that secondary metabolites such as alkaloids, coumarins, lignans and xanthones accumulate in more oxidized form in plant species grown in Mongolia. This principle is also demonstrated in the structure of diterpenoid alkaloids isolated from plants of Ranunculaceae family grown in Mongolia. As can be seen from alkaloids 11-acetyl-1, 19-epoxydenudatine and turpelline each contain 4 oxygen atoms, which is more oxygen atoms than in commonly-occurring C-20 diterpenoid alkaloids. Except turpelline no other C-20 alkaloid containing four hydroxyl groups was found in nature. Altaconitine is a newly discovered alkaloid which contains functional groups with highest number of oxygen atoms among C-19 diterpenoid alkaloids. Ring “A” in altaconitine structure is substituted at C-1, C-2 and C-3 positions with 2, 3-transdiol system, making altaconitine a unique structure found in nature.

Medicinal plants - Therapeutic effective compounds
Authors: G Odontuya
Published: May 2019

In plants, substances starting with a simple skeleton to highly complex chemical structures having specific activities are synthesized. Plants are still considered a resource of valuable raw materials for producing different therapeutic and health supporting products, as well as a pool of significant pharmacological active compounds. According to the analysis of the recent PubMed research trends, it was observed that the number of scientific research interest targeting plant-derived natural products had increased. New approaches for discovery of medicinal plants, isolation, identification and characterization of secondary metabolites, and resupply of plant-derived natural products are being developed. Meanwhile, the usage of medicinal plants and plant-derived natural products for any disease conditions is being increased worldwide. There is a limited possibility to isolate therapeutically active compounds from natural-originated plants and resupply them in the market. Therefore, alternative resupply approaches are being developed that they rely on biotechnological products and chemical synthesis. Currently, the research on medicinal plants and plant-derived secondary products is going with success using a broad interdisciplinary approach of chemical and biological sciences involving advanced technologies. Medicinal plants are a source of therapeutically active compounds and new drugs, and other health supporting products.

Published: May 2019

The paper addresses planning issues of hay land based on new methods of suitability and need’s assessment of local area.  In order to develop the hay land future use and planning for 2023 of Erdenetsagaan soum, Sukhbaatar aimag, the assessment of the haymaking situation, the number of livestock growth and needs of nutritional resources for animal husbandry were calculated. According to the tested new suitability assessment of hay land, 4.37 percent or 74164 ha of land are most suitable, and 29.21 percent or 496014.3 ha are unsuitable. In order to calculate the nutritional needs of livestock in the future, the demand of green fodder for hay cut is estimated at 6712 t in 2023. The need for this fodder supply requires 8391 ha hay fields in 2023. Thus, demand (6712 t hay from 8391 ha of field) of green fodder will be supplied after proper implementation of plan (74164 ha suitable field to hay land usage).

Des/Re/Escrevendo a história dos meios de comunicação: quatro contribuições a partir das Arqueologias das mídias
Authors: Telles Marcio
Published: May 2019

Como contraproposta à historiografia tradicional das mídias, as Arqueologias das mídias almejam descobrir histórias alternativas à narrativa positivista, criando ruídos nas certezas quanto ao progresso tecnológico. São muitas as maneiras de colocar tal projeto em prática, todos tendo como centralidade quatro processos de escrita: des-escrever, descrever, escrever e re-escrever as histórias dos meios. Neste artigo, foco em quatro abordagens e retiro de cada uma delas uma tese central: Kittler/Parikka (materialidade), Zelinski (variação), Kluitenberg (imaginário) e Ernst (arqueografia), que contribuem para os estudos de mídia, mas são, a meu ver, ainda insuficientes para lidar com os processos comunicacionais.
Estudo da sorção de césio em solos: avaliação do desempenho em repositório de rejeitos radioativos

Published: May 2019

Amostras de solo provenientes de Minas Gerais (Brasil) foram investigadas quanto à capacidade de sorção de césio (Cs) com vistas a aplicação destes como material de enchimento em um repo-sitório para deposição de rejeitos radioativos de médio e baixo nível de atividade. Foram avaliadas cinco amostras de solo quanto à capacidade máxima de sorção de césio (Q), coeficiente de distri-buição (Kd), e outros parâmetros relacionados à sorção: capacidade de troca catiônica, granulome-tria, composição química e mineralógica. Os parâmetros de sorção (Q e Kd) foram determinados a partir do ajuste dos dados experimentais, obtidos em ensaios por batelada, a modelos de isotermas de sorção apropriados. Adicionalmente, realizou-se um estudo da correlação entre os parâmetros obtidos pelas isotermas e as demais propriedades dos solos. Evidenciou-se uma forte correlação entre algumas propriedades e a sorção para Cs, fazendo com que estas possam ser utilizadas co-mo indicativos na escolha de solos para serem empregados como camada de recheio em depósi-tos de rejeito radioativo. Dentre as amostras de solo estudadas, o argilossolo coletado em Conse-lheiro Pena demonstrou as melhores características de sorção, com valores de Kd de 90,50 mL.g-1 e capacidade máxima de sorção de 18,35 mg.g-1, sendo, portanto, o solo mais promissor para ser utilizado como material de enchimento.
The characterisation of underwater noise at facilities holding marine mammals
Authors: Houser DS , Mulsow J , Branstetter B , Moore PW , Finneran JJ , Xitco MJ
Published: May 2019

A collaborative effort was undertaken to delineate underwater noise levels within holding enclosures at marine mammal facilities. Ambient noise levels were measured under normal operating conditions in the enclosures of 14 participating facilities. Facility habitats varied from ocean environments to fully enclosed pools. The means and standard errors of the noise pressure spectral densities measured across all pools were similar to those measured in natural coastal environments with relatively low presence of anthropogenic noise. Highest levels of noise in land-based pools were generally at frequencies < 2 kHz and primarily due to the operation of water treatment/filtration systems. Noise levels in land-based pools were comparable to or lower than semi-natural and natural systems at higher frequencies because of the presence of biological noise sources in these systems (eg snapping shrimp [Alpheus spp]). For odontocete enclosures, the whales themselves were often the greatest source of sound at frequencies where the whales have their best hearing (~40-100 kHz). The potential for facility ambient noise to acoustically mask odontocete communication signals and echolocation clicks appears to be low. In general, when noise was elevated it was at frequencies outside the typical frequency ranges of whistles and echolocation clicks, and where odontocetes have poor hearing sensitivity. Occasional noise issues were found; it is therefore recommended that facilities periodically assess enclosure noise conditions to optimise animal management and welfare.

Published: May 2019

This main objective of this paper is to examine the properties of the GARCHmodel and its usefulness in modeling and forecasting the volatility of exchange ratemovements in selected EEC countries (Romania, Hungary and Serbia). The dailyreturns of exchange rates on Hungarian forint (HUF), Romanian lei (ROL) andSerbian dinar (RSD), all against the US dollar are analyzed during the period 03.January 2000 to 15. April 2013 in respect. In order to measure the involved risk,symmetric and asymmetric GARCH models are applied. The accuracy of exchangerate volatility forecast is evaluated through reference to the most commonly usedcriteria. These include a Mincer-Zarnowitz regression based test, Mean AbsoluteError (MAE), Root Mean Square Error (RMSE) and Diebold and Mariano test (DMtest). The results of Mincer-Zarnowitz regression test for selected exchange ratereturn series showed a clear lack of explanotory power and sub-optimality of theTGARCH model. The results of the Mean Absolute Error (MAE) and the Root MeanSquare Error (RMSE) for the forecasted volatility showed that symmetric modelbetter predict conditional variance of the exchange rate returns, but estimating resultsindicating that the parameters of forecasts are not satisfactory, i.e. models have littlepredictive power. Results for Diebold-Mariano test results for Diebold-Mariano testshowed that symmetric model outperforming TGRACH forecast in case of Hungarianforint and Serbian dinar sample series, and that only in case of Romania lei TGARCHoutperforming the GARCH forecast.

ANALIZA UTICAJA LIDERSTVA KAO SKUPA VJEŠTINA NA EFEKTIVNO VOĐENJE POSLOVNIH PROCESA
Authors: Sefić Senad
Published: May 2019

U radu je prikazan model liderstva baziran na tri skupine liderskih vještina(tehničke, humanističke i konceptualne), a koje menadžeri sva tri hijerarhijska nivoa(operativni, srednji i visoki) posjeduju i primjenjuju u svom djelokrugu rada, kako bišto efektivnije vodili poslovne procese u svojim organizacijama. Analizom dobijenihrezultata utvrđeno je da menadžeri sva tri nivoa posjeduju i u svom radu koristeodređene liderske vještine, ali da je snaga tih vještina različita u zavisnosti od nivoa ukojem menadžer djeluje, te da postoji dosta liderskih vještina čije bi usvajanje odstrane menadžera i njihova praktična primjena u poslovnim procesima koje vode,značajno olakšalo vođenje tih procesa, uz istovremeno povećanje stepena njihoveefektivnosti. U ovom kontekstu, u radu su date i neke preporuke mladimmenadžerima kako mogu usvojiti nove i razvijati postojeće liderske vještine kojeposjeduju. U radu je potvrđena postavljena hipoteza da menadžeri sa snažnijimliderskim vještinama lakše i efektivnije vode poslovne procese koji su u djelokrugunjihovog rada, od menadžera koji imaju manje snažne liderske kompetencije. Dakle,utvrđeno je postojanje snažne korelacije između liderskih vještina i efikasnostivođenja poslovnih procesa na svim hijerarhijskim nivoima menadžmenta.
