description: Abstract

This article aims to identify the determinants of organizational innovation on the performance of Small and Medium Enterprises (SMEs) by looking at research trends, data sets, and research methods. The industrial era 4.0 brings organizations, including SMEs, into a complex, dynamic, and interconnected environment full of unpredictability and rapid change. For this reason, SMEs need to consider internal and external factors in the study of organizational innovation. Knowledge sharing is one of the ways that companies can optimize information and knowledge obtained from partners and competitors in identifying market opportunities. This article uses a systematic literature review method to elaborate on the literature related to determining the impact of organizational innovation on SME performance. Twenty-six articles reviewed in this study were sourced from Google Scholar by adding the keyword Elsevier in the search mode. This literature review concludes that current research on the determinants of organizational innovation on SME performance focuses on two topics and trends: estimation and classification. In addition, 81% of the selected studies used private datasets, and 19% used public datasets. Twelve different methods have been applied to address the impact of organizational innovation on SME performance. Of these twelve methods, three were identified as the most widely used in the abovementioned topic. They are Qualitative approaches (QA), Linear Regression Analysis (LRA), and Structural Equation Modeling (SEM).

description: We propose an enantio-detection method of chiral molecules in a cavity with external drive. The chiral molecules are coupled with a quantized cavity field and two classical light fields to form the cyclic three-level systems. The chirality-dependent cavity-assisted three-photon process in the three-level systems leads to the generation of intracavity photons. Simultaneously, the drive field also results in the chirality-independent process of the generation of intracavity photons. Based on the interference between the intracavity photons generated from these two processes, one can detect the enantiomeric excess of chiral mixture via monitoring the transmission rate of the drive field.

description: Observations of cold molecular gas reservoirs are critical for understanding the shutdown of star formation in massive galaxies. While dust continuum is an efficient and affordable tracer, this method relies upon the assumption of a "normal" molecular-gas to dust mass ratio, $δ_{\mathrm{GDR}}$, typically of order one hundred. Recent null detections of quiescent galaxies in deep dust continuum observations support a picture where the cold gas and dust has been rapidly depleted or expelled. In this work, we present another viable explanation: a significant fraction of galaxies with low star formation per unit stellar mass are predicted to have extreme $δ_{\mathrm{GDR}}$ ratios. We show that simulated massive quiescent galaxies at $0 < z < 3$ in the \textsc{simba} cosmological simulations have $δ_{\mathrm{GDR}}$ values that extend $>$4 orders of magnitude. The dust in most simulated quiescent galaxies is destroyed significantly more rapidly than the molecular gas depletes, and cannot be replenished. The transition from star-forming to quiescent halts dust formation via star formation processes, with dust subsequently destroyed by supernova shocks and thermal sputtering of dust grains embedded in hot plasma. After this point, the dust growth rate in the models is not sufficient to overcome the loss of $>$3 orders of magnitude in dust mass to return to normal values of $δ_{\mathrm{GDR}}$ despite having high metallicity. Our results indicate that it is not straight forward to use a single observational indicator to robustly pre-select exotic versus normal ratios. These simulations make strong predictions that can be tested with millimeter facilities.

title: On-Task Behavior for Students in a Resource Classroom Setting: Effects of Activity Schedules on On-Task Behavior
Creators: name: Mattson, Stephanie L.
Publisher: name: Utah State University
Year: 2018

description: Students who receive special education services in resource classroom settings often engage in low levels of on-task behavior during independent work time. Given the independent work demands in middle school classrooms, it is crucial for students who receive services in a resource classroom to engage in high levels of on-task behavior. The researchers examined the effects of activity schedules on on-task behavior, on-schedule behavior, and percentage of work problems correct in four middle school students receiving special education services in a resource math classroom. Results of the study demonstrate that on-task and on-schedule behavior increased for all participants following the implementation of the activity schedule in both math and language arts classroom settings. Both students and teachers indicated that they liked the intervention and the activity schedule improved on-task behavior. Results of this study extend the use of activity schedules to a novel setting and participant population.
title: Effects of Livestock Grazing Management Practices on Greater Sage-Grouse Nest and Female Survival
Creators: name: Dettenmaier, Seth J.
Publisher: name: Utah State University
Year: 2018

description: The decline in greater sage-grouse (Centrocercus urophasianus; sage-grouse) populations across western North America has been primarily attributed to loss and fragmentation of their sagebrush (Artemisia spp.) habitats. This habitat loss is largely the result of increased human activities, with grazing by domestic livestock as the most predominant land use across the sagebrush ecosystem in North America. The goal of my research was to increase our understanding of the effects of livestock on sage-grouse populations. I reviewed the peer-reviewed literature for all published studies that reported potential effects of grazing on grouse species worldwide. I found that there was an overall negative effect of domestic livestock grazing on grouse populations in general.
I compared sage-grouse nest success on two study sites managed under differing prescribed livestock grazing practices to determine their relative effects on sage-grouse nest survival. I found that nest survival was slightly higher in areas managed under high-intensity low-frequency rest-rotation practices. The difference was not statistically significant (P < 0.05). However, these areas received lower precipitation and were grazed at a higher stocking rate (AUM · ha-1) without negatively affecting nest survival compared to areas of that were mostly grazed as single pastures from May-September.
Because livestock grazing in the sagebrush ecosystem has been historically facilitated with sagebrush reduction treatments to increase forage for livestock, I compared the relative effects of these treatments with the more direct effect from livestock grazing. Sagebrush treatments were found to have a greater effect on female sage-grouse survival than livestock grazing. This understanding can be useful for land managers looking to attenuate the effects of management decisions related to livestock grazing systems in the sagebrush ecosystem.

description: Molecular emission was imaged with ALMA from numerous components near and within bright H2-emitting knots and absorbing dust globules in the Crab Nebula. These observations provide a critical test of how energetic photons and particles produced in a young supernova remnant interact with gas, cleanly differentiating between competing models. The four fields targeted show contrasting properties but within them, seventeen distinct molecular clouds are identified with CO emission; a few also show emission from HCO+, SiO and/or SO. These observations are compared with Cloudy models of these knots. It has been suggested that the Crab filaments present an exotic environment in which H2 emission comes from a mostly-neutral zone probably heated by cosmic rays produced in the supernova surrounding a cool core of molecular gas. Our model is consistent with the observed CO J=3-2 line strength. These molecular line emitting knots in the Crab present a novel phase of the ISM representative of many important astrophysical environments.

title: Weaving a Religious Community: Monasticism, Authority, and Theology in Gujarat, 1830-1905
Creators: name: Patel, Kirtan
Publisher: name: Utah State University
Year: 2018

description: This thesis demonstrates the intersection of caste, doctrine, religious authority and monasticism in the Swaminarayan sampradāy, a Hindu devotional tradition founded by Sahajānand Svāmī. Religious traditions affected indirectly or minimally by colonialism or the nationalist struggle have seldom been rigorously studied. This thesis brings attention to the Swaminarayan sampradāy to highlight how pervasive societal discourses like that of caste and internal doctrinal developments, impacted religious developments concerning authority, hierarchy, and power. The reification of a doctrine and the creation of a theological office, coupled with the deification of a monk, Guṇātītānand Svāmī, and his low-caste disciple Prāgjī manifested a fractious environment in which theology, authority and ideas about monasticism came to be contested. Theological ideas drove Prāgjī’s developing community, who adapted their devotion to Prāgjī as a result of stifling institutional politics and a modernizing Gujarat. Prāgjī’s incessant preaching, distinct theological beliefs and own budding community, which adored him, changed the course of Swaminarayan Hinduism in western India.

description: Abstract

The main objective of this research is to understand and analyze descriptively related problems Inequality in access to education, so that problems can be identified and solutions can be found. The qualitative descriptive type took 50 key informants proportionally to obtain sharp and in-depth information, and supported by secondary data the results of this research indicate that special classroom programs can help students from advantaged backgrounds obtain a better education. Whereas students from disadvantaged families often do not have access to the information and resources needed to support them in their education. Special education” can be defined as the science that consists of various classes of extraordinary learners in terms of assessment, diagnosis, and the development of appropriate educational initiatives and teaching methods. Several actions that can be taken to overcome inequality in access to education, increasing awareness about stigma and discrimination, resources through the schools, teachers and supporting facilities are the same. Education has a contribution to social aspects so that it can bring changes in behavior, morals, better ethics and social and economic welfare.
A note on the Mordell-Weil rank modulo n

description: Conjecturally, the parity of the Mordell-Weil rank of an elliptic curve over a number field K is determined by its root number. The root number is a product of local root numbers, so the rank modulo 2 is conjecturally the sum over all places of K of a function of elliptic curves over local fields. This note shows that there can be no analogue for the rank modulo 3, 4 or 5, or for the rank itself. In fact, standard conjectures for elliptic curves imply that there is no analogue modulo n for any n>2, so this is purely a parity phenomenon.

High temperature ideal Weyl semimetal phase and Chern insulator phase in ferromagnetic BaEuNiOsO6 and its (111) (BaEuNiOsO6)/(BaTiO3)10 superlattice

description: Weyl semimetals (WSMs) have recently stimulated intensive interest because they exhibit fascinating physical properties and also promise exciting technological applications. So far, however, the few conrmed magnetic WSMs generally have a large number of Weyl points either located away from the Fermi level (EF ) or shrouded by nontopological Fermi surface pockets. Based on first principles density functional theory calculations, we establish cubic double perovskite BaEuNiOsO6 to be a high Curie temperature (Tc) ferromagnetic WSM with magnetization along the [111] direction, just two pairs of Weyl points at the EF and Tc = 325 K. The strong ferromagnetism is attributed to the strong ferromagnetic Ni 3d-Eu 4f-Os 5d coupling induced by the substitution of half of Ba atoms with Eu atoms in double perovskite Ba2NiOsO6. Moreover, the momentum separation of one Weyl point pair is large, thus giving rise to not only a long (001) surface Fermi arc but also large anomalous Hall conductivity. Intriguingly, as a unique physical result of a ferromagnetic WSM, the (111) BaEuNiOsO6 monolayer superlattice (BaEuNiOsO6)/(BaTiO3)10, being its (111) quantum-well structure, is found to be a high temperature (Tc = 210 K) Chern insulator with a large band gap of 190 meV. Therefore, cubic double perovskite BaEuNiOsO6 will provide a superior high temperature material plotform for exploring fundamental physics of Weyl fermions and its (111) monolayer superlattices will offer a high temperature magnetic topological insulator for studying exotic quantum phenomena such as quantum anomalous Hall effect.

description: The research examines which cultural and linguistic instruments can be offered to provide adult migrants with formative access to citizenship competences. Starting  from the questions:
How can individuals of all community groups present in a nation-state acquire high standards of linguistic, sociolinguistic and discourse competences in order to be fully integrated, that is to participate and be included in social activities in the public domain such as work and institutional environments?

How are these competencies developed in an educational context?

How do adult migrants behave linguistically in this context, according to their needs and motivations?

The research hypothesis aimed at outlining a formative project of citizenship education targeted at adult foreign citizens, where a central role is assigned both to law education and linguistic education.

Acoordingly, as the study considered if the introduction of a law programme in a second language course could be conceived as an opportunity to further the access to active citizenship and social participation, a corpus of audiodata was collected in law classes of an Italian adult professional course attended by a 50% of foreign students. The observation was conducted on teacher and learner talk and learner participation in classroom interaction when curriculum legal topics were introduced and discussed. In the classroom law discourse two dimensions were analyzed: the legal knowledge construction and the participants’ interpersonal and identity construction.

From the analysis, the understanding is that drawn that law classes seem to represent an educational setting where foreign citizens have an opportunity to learn and practise citizenship. The social and pragmatic approach to legal contents plays a relevant role, in a subject which, in non-academic contexts, loses its technical specificity and refers to law as a product of social representation. In the observed educational environment, where students are adults who bring into the classroom multiple personal and social identities, legal topics have the advantage of increasing adult migrants’ motivation to ‘go back to school’ as they are likely to give hints, if not provide solutions, to problems relating to participation in socio-institutional activities. At the same time, these contents offer an ideal context where individuals can acquire high discourse competences and citizenship skills, such as agency and critical reflection. Besides, the analysis reveals that providing adult learners with materials that focus on rights, politics and the law, i.e. with materials which stimulate discussion on concerns affecting their daily lives, is welcomed by learners themselves, who might appreciate the integration of these same topics in a second language course.
title: Water Entry Cavity Dynamics

Publisher: name: Utah State University

description: When a sphere or a stream of water hits the surface of a pool of water and enters a crater or air cavity often forms. This topic has been studied, both formally and informally, for a long time. This dissertation investigates four areas of water impact that are still poorly understood using high-speed photography. First, it examines a stream of droplets impacting on a pool of water, similar to a faucet drizzling into a full bucket. For these types of impacts we predict the depth, diameter, velocity, and shape of the cavities that the droplet stream forms. Second, it examines what occurs when a sphere impacts a pool of soapy water, such as a bubble bath or kitchen sink. The minimum velocity for a cavity to form decreases when soap is present. If the water has bubbles on the surface, the sphere will always form a cavity. Third, it examines how different coatings on a sphere (car wax, etc.) affect whether the sphere forms a cavity, and it shows how the coating affect the shape of that cavity. Fourth, when objects impact a water surface they experience a large force, which many people have noticed when participating in cliff jumping, high diving, and belly flop competitions. We show that the force of impact can be reduced by 75% simply by allowing a mass of water to impact in front of the object.
title: Advancing Methods to Quantify Actual Evapotranspiration in Stony Soil Ecosystems
Creators: name: Parajuli, Kshitij
Publisher: name: Utah State University
Year: 2018

description: Water is undeniably among the most important natural resources and the most critical in semi-arid regions like the Intermountain West of the United States. Such regions are characterized by low precipitation, the majority of which is transferred to the atmosphere from the soil and vegetation as evapotranspiration (ET). Quantification of ET is thus crucial for understanding the balance of water within the region, which is important for efficiently planning the available water resources. This study was motivated towards advancing the estimation of actual ET (ETA) in mountain ecosystems, where the variation in different types of vegetation and non-uniformity of soil including considerable stone content creates challenges for estimating water use as ET. With the aim of addressing the effect of stone content in controlling soil moisture and ET, this study examined the influence of stone content on bulk soil hydraulic properties. An averaging model referred to as a binary mixing model was used to describe the way in which water is held and released in stony soil. This approach was based on the individual hydraulic behavior of the background soil and of the stones within the soil. The effect of soil stone content on ETA was evaluated by accounting for the water retention properties of stones in the soil using a numerical simulation model (HYDRUS-1D). The results revealed overestimation of simulated ETA when effects of stone content were not accounted for in comparison to ETA measured by the state-of-the-art “eddy covariance” measurement method for ETA. An even larger-scale model was evaluated, named the Noah-Multiphysics (Noah-MP) land surface model. The land surface model was run using different arrangements of complexity to determine the importance of stone content information on simulation results. The version of the model with information about stone content along with detailed soil properties was able to provide the best Noah-MP prediction of ET. The study suggests that improvement in representation of soil properties including stone content information, can substantially advance the ability of numerical and land surface models to more accurately simulate soil water flow and ETA.

description: The main goal of this research is to develop algorithms to facilitate the use of a new type of antenna, called multifunctional reconfigurable antenna (MRA). Traditional antennas have fixed radiation properties which cannot be changed to adapt to different environments. To solve this problem, MRAs, which can dynamically change its operation frequency, radiation patter, and polarization, has gained a significant interest recently. Such antennas can support multiple radio access technologies with different sets of operational requirements. Reconfigurable antennas are considered smart antennas. The efficient use of smart antennas requires efficient and smart underlying algorithms. This dissertation focuses on developing efficient algorithms to exploit the reconfigurability of MRAs to tap on the superior performances offered by additional degrees of freedom compared to legacy antenna systems.

description: The physiological effects of vaccination against SARS-CoV-2 (COVID-19) are well documented, yet the behavioural effects not well known. Risk compensation suggests that gains in personal safety, as a result of vaccination, are offset by increases in risky behaviour, such as socialising, commuting and working outside the home. This is potentially important because transmission of SARS-CoV-2 is driven by contacts, which could be amplified by vaccine-related risk compensation. Here, we show that behaviours were overall unrelated to personal vaccination, but-adjusting for variation in mitigation policies-were responsive to the level of vaccination in the wider population: individuals in the UK were risk compensating when rates of vaccination were rising. This effect was observed across four nations of the UK, each of which varied policies autonomously.

description: Last and nearest GRB-XRF 080109 has been an exceptional lesson on GRB nature. After a decade (since 25 April 08) we know that Supernovae may often contain a Jet. Its persistent activity may shine on axis as a GRBs. Such a persistent, thin beamed gamma jet may be powered by either a BH (Black Holes) or Pulsars. Late stages of these jets may loose the SN traces and appear as a short GRB or a long orphan GRB (depending on jet angular velocity and view angle). XRF are peripherical viewing of the jets. These precessing and spinning gamma jet are originated by Inverse Compton and-or Synchrotron Radiation at pulsars or micro-quasars sources, by ultra-relativistic electrons. These Jets are most powerful at Supernova birth, blazing, once on axis, to us and flashing GRB detector. The trembling of the thin jet explains naturally the observed erratic multi-explosive structure of different GRBs. The jets are precessing (by binary companion or inner disk asymmetry) and decaying by power on time scales of few hours, but they keep staying inside the observer cone view only a few seconds duration times (GRB); the jet is thinner in gamma and wider in X band. This explain the wider and longer X GRB afterglow duration and the rare presence of X-ray precursors.

Creators: name: Towfiq, MD Asaduzzaman
Publisher: name: Utah State University
Year: 2018

description: Antennas enable wireless communication by transmission and reception of electromagnetic (EM) signals, which carry information is space. Signal reception and hence the quality of service depends significantly on the antenna properties, e.g. radiation pattern, operational frequency, and polarization. Legacy antennas, with their fixed properties, fail to adapt to the changing environment and degrade signal quality. Reconfigurable antennas (Ras) capable of changing their properties dynamically increase the capacity and data rate of wireless systems while offering a compact design. However, these advantages come at the cost of increased complexity compared to legacy antennas. Therefore it is important to design Ras with minimal complexity. To that end, this dissertation focuses on the development of a novel approach, three different Ras operation at three different frequency bands have been designed, fabricated and characterized. First RA works at the 5GHz band (4.9-5.1GHz) and obtains on current beam steering and 3-dB beam width variability. An algorithm to choose the optimum mode of operation has also been developed. The design approach introduced in first RA has been exploited to design the second RA, which achieves beam steering and beam width variability for two polarizations and operates a the 28 GHz band (27.5-28.3 GHz). The third RA operates at the 3GHz band and simultaneously reconfigures impedance and radiation patterns.

Year: 2018

description: Spider silks are incredible natural materials that possess desirable combinations of strength, elasticity, weight, and robustness. Other properties such as biocompatibility and biodegradability further increase the worth of these materials. The possibility of farming spiders is impractical due to spiders’ natural behaviors. Modern biotechnologies have allowed for recombinant spider silk proteins (rSSps) to be produced without the use of spiders. However, the features responsible for spider silks impressive properties can cause difficulties with producing silk materials. A recently developed water-based and biomimetic solvation method has provided a solution to such difficulties and has also led to novel silk biomaterials. Most notable among these materials are; coatings, fibers, adhesives, films, foams, hydrogels, aerogels, capsules, and sponges. Many of these material possess specific properties that may be suitable for many commercial, industrial, and biomedical uses. This study has developed numerous spider silk biomaterials, identified their essential properties and features, provided preliminary evidence for various applications, and identified directions for future studies and uses.

description: The description of complex configuration is a difficult issue. We present a powerful technique for cluster identification and characterization. The scheme is designed to treat with and analyze the experimental and/or simulation data from various methods. Main steps are as follows. We first divide the space using face or volume elements from discrete points. Then, combine the elements with the same and/or similar properties to construct clusters with special physical characterizations. In the algorithm, we adopt administrative structure of hierarchy-tree for spatial bodies such as points, lines, faces, blocks, and clusters. Two fast search algorithms with the complexity are realized. The establishing of the hierarchy-tree and the fast searching of spatial bodies are general, which are independent of spatial dimensions. Therefore, it is easy to extend the skill to other fields. As a verification and validation, we treated with and analyzed some two-dimensional and three-dimensional random data.

description: This paper applies the -firm concentration ratio and the Herfindahl-Hirschman Index to Greek hotel industry. The results indicate that the concentration of the industry is quite low not only for the total market but also for the separate markets of the different stars categories. Moreover, it is found that there is a significant difference between the results obtained for the highest categories and those for the lowest categories, the latter displaying much lower concentration. Since the level of concentration in an industry is an important factor of the market structure, the economic policy implications of the findings of this paper would be of some importance for the relevant authorities.

description: Two-dimensional (2D) van der Waals (vdW) magnets have been a fertile playground for the discovery and exploration of physical phenomena and new physics. In this Letter, we report the observation of an anomalous thermal Hall effect (THE) with \k{appa}_xy ~ 1x10^(-2) W K^(-1) m^(-1) in an insulating van der Waals ferromagnet VI3. The thermal Hall signal persists in the absence of an external magnetic field and flips sign upon the switching of the magnetization. In combination with theoretical calculations, we show that VI3 exhibits a dual nature of the THE, i.e., dominated by topological magnons hosted by the ferromagnetic honeycomb lattice at higher temperatures and by phonons induced by the magnon-phonon coupling at lower temperatures. Our results not only position VI3 as the first ferromagnetic system to investigate both anomalous magnon and phonon THEs, but also render it as a potential platform for spintronics/magnonics applications.

Subjects: subject: Nuclear Experiment (nucl-ex)

description: We study the beam-energy and system-size dependence of ϕmeson production (using the hadronic decay mode ϕ-- K+K-) by comparing the new results from Cu+Cu collisions and previously reported Au+Au collisions at \sqrt{s_NN} = 62.4 and 200 GeV measured in the STAR experiment at RHIC. Data presented are from mid-rapidity (|y|<0.5) for 0.4 < pT < 5 GeV/c. At a given beam energy, the transverse momentum distributions for ϕmesons are observed to be similar in yield and shape for Cu+Cu and Au+Au colliding systems with similar average numbers of participating nucleons. The ϕmeson yields in nucleus-nucleus collisions, normalised by the average number of participating nucleons, are found to be enhanced relative to those from p+p collisions with a different trend compared to strange baryons. The enhancement for ϕmesons is observed to be higher at \sqrt{s_NN} = 200 GeV compared to 62.4 GeV. These observations for the produced ϕ(s\bar{s}) mesons clearly suggest that, at these collision energies, the source of enhancement of strange hadrons is related to the formation of a dense partonic medium in high energy nucleus-nucleus collisions and cannot be alone due to canonical suppression of their production in smaller systems.

description: Tourism is a pivotal economic sector with major social impact on local communities and a development pillar for both advanced and emerging countries. Tourism development has a valuable impact on employment and output, contributing to post-crisis economic recovery. Under the hypothesis that tourism development is a complex phenomenon shaped by economic growth and negatively influenced by the most recent financial crisis, this study proposes a comprehensive analysis of the spatial distribution of tourism activities across European countries and regions during recession time (2008-2014). Changes in the location quotient of tourism jobs were computed to evaluate the importance of this sector across European regions, providing an informative base for policies enhancing tourism competitiveness. The 2007 recession resulted a spatiallyheterogeneous impact on tourism specialization across European regions, maintaining a strong (and sometimes declining) base in southern Europe, promoting tourism diversification with sparse employment growth in western and central Europe and strengthening cultural and natural attraction poles in northern Europe.

Massive stars as thermonuclear reactors and their explosions following core collapse

description: Nuclear reactions transform atomic nuclei inside stars. This is the process of stellar nucleosynthesis. The basic concepts of determining nuclear reaction rates inside stars are reviewed. How stars manage to burn their fuel so slowly most of the time are also considered. Stellar thermonuclear reactions involving protons in hydrostatic burning are discussed first. Then I discuss triple alpha reactions in the helium burning stage. Carbon and oxygen survive in red giant stars because of the nuclear structure of oxygen and neon. Further nuclear burning of carbon, neon, oxygen and silicon in quiescent conditions are discussed next. In the subsequent core-collapse phase, neutronization due to electron capture from the top of the Fermi sea in a degenerate core takes place. The expected signal of neutrinos from a nearby supernova is calculated. The supernova often explodes inside a dense circumstellar medium, which is established due to the progenitor star losing its outermost envelope in a stellar wind or mass transfer in a binary system. The nature of the circumstellar medium and the ejecta of the supernova and their dynamics are revealed by observations in the optical, IR, radio, and X-ray bands, and I discuss some of these observations and their interpretations.

Publisher: name: tourismos
Year: 2017

description: This study was done to understand the gaps between two industries for the same concept named internal marketing. The study fills the gap with the help of defining IM from the literature review and then transfiguring the idea for the tourism industry focussed towards DMOs (Destination Marketing Organizations). The study has got 13 variables of internal marketing and redefined them for the tourism sector, i.e., inter-functional coordination and integration, customer orientation, marketing-like approach, job satisfaction, empowerment, stakeholder’s motivation, quality of service, stakeholder’s development, training and development, vision of the firm, strategic rewards, internal communication and senior leadership. These definitions can be helpful for planners and managers of DMOs in weaving a strategy to obtain a better performance from all stakeholders. Government departments, agencies, consultancies, and NTOs can also use these definitions for policy planning and implementation.

description: Source identification problems have multiple applications in engineering such as the identification of fissures in materials, determination of sources in electromagnetic fields or geophysical applications, detection of contaminant sources, among others. In this work we are concerned with the determination of a time-dependent source in a transport equation from noisy data measured at a fixed position. By means of Fourier techniques can be shown that the problem is ill-posed in the sense that the solution exists but it does not vary continuously with the data. A number of different techniques were developed by other authors to approximate the solution. In this work, we consider a family of parametric regularization operators to deal with the ill-posedness of the problem. We proposed a manner to select the regularization parameter as a function of noise level in data in order to obtain a regularized solution that approximate the unknown source. We find a Hölder type bound for the error of the approximated source when the unknown function is considered to be bounded in a given norm. Numerical examples illustrate the convergence and stability of the method.

description: Abstract

Fuchs Endothelial Corneal Dystrophy (FECD) is a hereditary disease characterized by progressive endothelial cell loss, guttae formation, and worsening stromal edema. It typically presents in the fourth decade of life or later. Patients with FECD are at increased risk of developing cataracts as the corneal disease progresses. Simultaneous optical penetrating keratoplasty, lens extraction, and intraocular lens implantation is an effective treatment options for FECD patients presenting with cataract.

THE LOGISTICS SYSTEM OF BICYCLE TOURISM DESTINATION*
Creators: name: Slavic, Natasa
Publisher: name: tourismos
Year: 2017

description: The purpose of this paper is to explore the applicability of the theoretical concept of the tourism logistics system to the bicycle tourism market. The objective is to generate a model of a bicycle tourism destination logistics system based on the conceptual framework and compare it with the actual modus operandi of bicycle destinations. Field research was realized by implementing observational and interview techniques on the example of a bicycle destination area in Croatia. Modelling and systems theory scientific methods were combined in generating three models in the process of applying a logistics approach to bicycle tourism destination system research. The paper provides the framework of an optimal bicycle destination structure and offers managerial implications for efficient bicycle tourism destination management. While the tourism logistics system logic is compatible with bicycle destinations’ requirements, the theoretically based structure is more advanced than the researched system.
