In the present work for the creation of manufacturing technology forming statok higher heat resistance used the "cortical" method with the use of thermal spraying (TS). The essence of the method is as follows: on the model, which is a mirror copy of the forming surface of the insert, a working layer up to 3 mm thick of wear-resistant powder materials is applied by plasma spraying, and then a structural layer 10...20 mm thick of more plastic and cheap materials. The dusty "crust" process from which it will be established in a form holder, and separate from model. Working surface FV after separation from the model in size, shape and roughness fully complies with the requirements of the drawing, ie it is not subjected to additional processing. For reasons of availability and relatively low cost for the working layers forming inserts made of "cortical" method with the use of GTN, the most often used powders camofluage chromium-Nickel alloy ПН77Х15С3Р2 or metalloids brands ПН70Ю30 and ПН85Ю15. Research into the optimal composition of the mixture of powders ПН70Ю30 and ПН77Х15С3Р2 conducted on special samples of steel 45, which is a plate with dimensions 5050 mm around the perimeter with ribs protruding above the work surface to a height of 1 mm. working surface is chrome-plated and termoobrabotki to earn a guaranteed layer of Cr2O3, which provides the adhesive connection of the coating and the substrate at the level of 5 MPa. During the experiments, the composition of the mixture of powders ranged from 95% PN70YU30 + 5% PN77H15S3R2 to 70% PN70YU30 + 30% PN77H15S3R2 in steps of 5%. The coating produced according to the following mode: the current is 500 A, voltage - 60 V; the total consumption of powder - 1.5 kg/h; the sample temperature is 650 ℃; coating thickness - 0.5 mm. Deposited samples were placed in a muffle furnace and heated to a temperature of 1300 C, where they were kept for 1 hour. After cooling to room temperature, together with the furnace, the coatings were carefully separated from the samples and subjected to permeability tests for which they were placed in special containers smearing around the perimeter with special mastic. Then the coatings on the outside were covered with a layer of thick chalk, and kerosene was poured into the vessels. It is established that dusty coatings from a mixture of powders with a content of 20% or more of pn77h15s3r2 alloy practically do not have pores (kerosene within 24 hours did not penetrate the chalk-coated surface).

Published: December 2018

The main requirement for powders for additive 3d technologies is the spherical shape of the particles. Such particles are most compact in a certain volume and provide "fluidity" of the powder composition in the material supply systems with minimal resistance. In addition, the powder must contain a minimum amount of dissolved gas. The microstructure of the powder should be uniform and fine (with a uniform distribution of phase components). Based on the features of methods for producing spherical powders to obtain spherical granules of regulated grain, the technology of electroerosion dispersion, characterized by relatively low energy costs and environmental cleanliness of the process, is proposed. The main advantage of the proposed technology is the use of waste as raw materials, which is much cheaper than the pure components used in traditional technologies. In addition, this technology is powder, which allows powder-alloys. To develop technologies for the reuse of electrical erosion powders and to evaluate the effectiveness of their use, complex theoretical and experimental studies are required. The aim of this work to study the microhardness of the additive products of the electrical discharge machining of cobalt powders. For the proposed studies selected waste cobalt alloy brand CHMS "CELLET". Butyl alcohol (butanol-1) was used as a working liquid. To obtain the cobalt powders used for the installation of AED dielectric materials. Dispersion parameters: voltage 100 V, capacity 48 UF, pulse repetition rate 120 Hz. According to the results of the research, it was experimentally established that the microhardness of additive products obtained from electroerosion powders with an average particle size of 52.5 µm is 5.7 GPA.

Published: December 2018

This paper presents forward kinematics, inverse kinematics and Jacobian analysis of four-legged robot research. The kinematics analysis is the main problem of the legged robot. The four-legged robots are very complex more than wheeled robots. In this study,the four-legged robot of each leg calculates Denavit-Hartenberg (D-H) method,that is used for forward kinematics and the inverse is used the geometrical and mathematical methods.The Kinematic divided into two categories Forward Kinematic and Inverse Kinematics. The forward kinematic is calculated we knew the leg of endpoint position for the angles (θ1,θ2 and θ3 ). . Inverse kinematics is used to compute the joint angles which will achieve a desired position and orientation of the end-effector relative to the base frame. The Jacobian is one of the most important analyses for controlling smooth trajectory planning and execution in the derivation of the dynamic equation of robot motion.For calculation is used MATLAB software and robot modeling is used Simulink toolbox in MATLAB software. A program is obtained that calculate joint of angular velocity and angles to move from the desired position to target position. In this study are given different angular velocity and angle of the endpoint of the leg. The work mainly focuses on mechanical design, calculation of kinematic analysis, Jacobian function and experiment data of four-legged robots in MATLAB simulation.

One of the fundamental principle of the biosphere compatibility conception of cities and settlements is the principle of inhabitants' satisfaction of rational needs. The most vulnerable group of the city population is invalids, people with carriages, children, who are refered to the disabled population, so these are people, who move and get services and information with difficulties. It is important, that the number of the disabled population grows stably in the recent period. That is why the creation of the comfortable conditions for the disabled population is the main aim of the contemporaneity. During the last 15-20 years the attempts of drawing the disabled population in all the living sphere were undertaken more than once. But nowadays the problem of restriction possibility of disabled oopulation is relevant. "Charity" is the function of the city which reflects the disabled population's extent of satisfactions needs. "Charity" , which takes the main place among all the functions of the settlements , is not fulfilled practically on the territory of the modern cities and settlements. There is an evatuation of the function realization of "Charity" city in the aticle. The function were taken up the territory of the dwelling microdistrict of Kursk city. Also the results of the analysis have been made, the proposals have been shown and directed to solve the problem of the providing the disabled population with the convenience of the city life. The results can be served as the base for the realization of the proposals and recommendations.
CONTROL OF ACTIONS OF STEEL TANK IN WORKING
Authors: Vasilkin A. A.
Published: December 2018

In steel tanks made by the method of rolling, defects of a geometric shape often occur in the area of the welded welded joint of the wall. Subsequently, in these areas, as a result of low cycle fatigue, an unacceptable defect appears in the form of a crack, which makes it necessary to remove the reservoir from operation and carry out a set of measures for its repair. To determine the terms of safe operation of vertical steel tanks with geometric defects, it is proposed to use the methodology control of the actions of structures of load-bearing structures, one of the directions of which is the regulation of the stress-strain state of steel structures. To implement the possibility of regulating construction, it is necessary to identify such parameters, the change of which will give the maximum effect in achieving the set goals. As the indicated parameters, the design characteristics (material properties, design scheme, geometric characteristics) and factors of external influences (load, operating conditions) can act. To regulate the stress-strain state design of vertical steel tanks, the following regulators are proposed: product loading height, wall deflection arrow and permissible number of tank loading cycles. By numerical calculation of the VAT of the vertical steel tank design with geometric defects, the necessary values and values of the stress state are determined. Further, using known analytical dependencies from the field of fracture mechanics, it is possible to determine the permissible number of loading cycles of the reservoir before the appearance of a crack-like defect. The application of the methodology control of the actions of structures load-bearing structures, by means of a certain change in the established control parameters, allows increasing the number of loading cycles of the reservoir, thereby increasing the period of safe operation of the defective reservoir and thereby increasing the economic efficiency of the tank farm.
DEVELOPMENT OF INFORMATION AND COMMUNICATION INFRASTRUCTURE OF DISTRIBUTED COMPUTING SYSTEMS BASED ON THE CONCEPT "THE NETWORK IS THE COMPUTER"
Authors: Zinkin S. A. , Jaafar Mustafa Sadeq
Published: December 2018

The concept "network is a computer" that has been further developed in the form of a paradigm of cloud applications that have the properties of "multi-lease"and "live" database migration is considered. Of particular interest in this regard is the development of a middleware for large reconfigurable clustered server systems as part of the support of the "big data" concept. Therefore, an approach is being developed to design a reconfigurable and parametrically tuned system and functional architecture of distributed computing systems. In some cases, the implementation of this approach can provide increased efficiency and cost reduction of large software and hardware systems. The article categorizes distributed computing systems when taking into account the specifics of cloud, grid, cluster and other types of communal, parallel and distributed computations. It is recommended to use as a basis hybrid architectures that combine the positive properties of cloud, grid and cluster distributed computing systems. The concept of organization of distributed network computing as services, implemented at the client's request, is developed. A network model that describes the work of a hybrid cloud grid system with third-party auditors and cloud service providers, is proposed. A distinctive feature of the proposed model is that when implementing as a concept NCaaSoD (network architecture as a service on the user's request) before the execution of a request, such as Upload (uploading data to the cloud), meta-information about available resources in order to further create a virtual cluster from the available nodes of the network of the cloud service provider, and before requesting the download type request (request information from the cloud), information is requested about the nodes that store the results. Meta-information can be obtained not only from a third-party auditor, but also from a remote monitoring service. To further develop the proposed concepts to real technology, it is advisable to develop a methodology for transforming conceptual models of the system and functional architecture into specifications suitable for the formation of virtual topologies of a network computer such as NCaaSoD in a hybrid cloud environment.

Relación entre vida, escucha y estudios musicales en diferentes perfiles de alumnos del sureste español
Authors: Martínez Cantero Irene
Published: December 2018

Percepción y conocimiento de la música son dos aspectos estrechamente relacionados con emoción y motivación hacia la actividad musical. Además, la importancia de los últimos para el logro de los primeros ha sido verificada por numerosas disciplinas que proporcionan una parte del conocimiento global del aprendizaje y de la actividad musical: Estética (Collier, 2007), Musicología (Shaw, 2001), Moral (Fairlay, 2006), Política y economía (Fouce, y Pecourt, 2008), o Sexualidad (Trotta, 2009). Sin embargo, la psicología social y la neurociencia son, quizás, las más cercanas (Hargreaves, Hargreaves, & North, 2012; Sloboda, 2012; Ockelford, 2012). En este artículo se presenta una introducción del estado de la cuestión en músiconeuropsicología. Así mismo, se aportan datos sobre investigaciones previas generales y empíricos actuales para su concreción en tres estudios de casos de estudiantes diferenciados por grados de persistencia y de rendimiento en la actividad musical. Lo que se investiga en ellos es la igualdad o diferencia entre su vida musical y sus estudios musicales. Los resultados permiten discernir áreas comunes en las que el ambiente informal resulta revelador, pero también discrepancias por contexto de análisis (vida, escucha de música y estudios) y perfil del alumnado (éxito, rendimiento medio y abandono). Desde la reflexión sobre ellos, se resalta la necesidad de mayor presencia de aquello que el alumno vive en relación a la música en los estudios musicales. Su gran incidencia en aspectos emotivos y motivacionales determinará también su percepción y cognición musicales, derivando en el rendimiento y en la continuidad  de la actividad.
La pronunciación como variable expresiva en el canto en español:
Authors: Guzmán Mariano Nicolás
Published: December 2018

La formación de especialistas en música vocal promueve el desarrollo de habilidades fonéticas para el canto. Sin embargo, observamos que colocar el estudio de la pronunciación únicamente al servicio de problemas técnicos desalienta la exploración de sus potencialidades expresivas, lo que es favorecido por la disociación tradicional técnica/expresión y la dificultad de cuantificar la emoción. Asimismo, los estudios sobre dicción para el canto se centran en lenguas predominantes en la música académica (como italiano, alemán y francés). En consecuencia, la exploración de los usos expresivos de la pronunciación del español en el canto constituye un área de vacancia y un desconocimiento de su valor cultural e identitario. Bajo la hipótesis de que la pronunciación es empleada como variable expresiva en el canto, se propuso estudiar los usos expresivos de la articulación consonántica en la ejecución de música en español. Para ello, se describieron variables en la articulación de las consonantes /s/, /b/, /d/, /ɡ/, /ʒ/, /r̄/, /l/, /m/ y /n/ en 5 versiones representativas de “La Tempranera” de Carlos Guastavino interpretadas por cantantes hispanohablantes. Las tareas de segmentación, etiquetado, procesamiento y análisis de las señales fueron realizadas mediante Praat. Las variaciones en la articulación consonántica sugieren una correspondencia entre la pronunciación y la intencionalidad expresiva, que parece contribuir con una mejor declamación del contenido semántico y la conformación de “estilos de pronunciación” impulsados por razones idiosincrásicas y requisitos performáticos.
Construyendo el sentido conceptual en música
Authors: Nogueira Marcos
Published: December 2018

La contribución teórico-metodológica de las llamadas ciencias cognitivas corporeizadas fue absorbida por la investigación musical en los años 1990. A lo largo de los 20 años de desarrollo de un enactivismo musical, varios investigadores se han enfrentado al desafío de superar el modelo representativo de la tradición académica para explicar lo que le sucede a la mente cuando interactuamos con la música de manera creativa. Este artículo argumenta la validez de la hipótesis según la cual el enfoque de atención del descriptor regula las descripciones lingüísticas de su entendimiento musical. En el proceso de producir sentido, el oyente enfatiza una u otra de las dimensiones imaginativas que este estudio reconoce como categorización de movimientos, producción de imágenes formales y el establecimiento de predicados simbólicos. Además, el presente estudio sostiene que los eventos que provocan una orientación más significativa de la atención desencadenan un dispositivo cognitivo llamado respuesta de orientación que regula el enfoque de atención del oyente. Antes de esto, el desarrollo de un modelo estrictamente enactivista para la investigación de los modos de conceptualización del entendimiento musical expresada en las descripciones lingüísticas de los oyentes ofrece un acceso sin precedentes al camino que va desde el concepto hacia los sentidos (en su mayoría inconscientes) que son aún no conceptos. Estos son los significados con los que inventamos nuestros mundos musicales antes de conceptualizar el mundo musicalmente.

Published: December 2018

La música produce reacciones emocionales intensas, similares a las que producen otros estímulos. La capacidad de procesar estímulos musicales requiere de varios componentes de procesamiento e involucra diversas regiones del cerebro. Los pacientes con Demencia Tipo Alzheimer (DTA) presentan alteraciones en la memoria episódica y deficiencias en el procesamiento emocional de los estímulos visuales. El objetivo de este estudio es llevar a cabo una revisión bibliográfica evaluativa para determinar si existen disociaciones entre el juicio emocional musical y el procesamiento de otros aspectos musicales en DTA y brindar una explicación desde los modelos teóricos y bases anatómicas implicadas.

Los estudios mostraron que los pacientes con DTA muestran un rendimiento deficiente en algunos aspectos del procesamiento musical, como el global. A pesar de eso, se conserva el procesamiento emocional de las melodías. El componente de procesamiento emocional se conservaría en DTA. Y las áreas activadas son similares a los sujetos sanos, como el giro cingulado, el cerebelo y las áreas frontales. La música parece apuntar a procesos y áreas que se conservan en DTA. Esta revisión muestra la importancia de estudiar las emociones en la música, centrándose en lo que se conserva en DTA. Esta podría ser la clave para explicar la conservación relativa de la memoria musical en esta patología y para desarrollar tratamientos basados ​​en la música.

Research Data Management Practices: Synergies and Discords between Researchers and Institutions
Authors: Vanden-Hehir Sally , Cousijn Helena , Attalla Hesham
Published: December 2018

The aim of this study was to explore the synergies and discords in attitudes towards research data management (RDM) drivers and barriers for both researchers and institutions. Previous work has studied RDM from a single perspective, but not compared researchersâ€™ and institutionsâ€™ perspectives. We carried out qualitative interviews with researchers as well as institutional representatives to identify drivers and barriers, and to explore synergies and discords of both towards RDM. We mapped these to a data lifecycle model and found that the contradictions occur at early stages in the lifecycle of data and the synergies occur at the later stages. This means that for future successful RDM, the points of discord at the start of the data lifecycle must be overcome. Finally, we conclude by proposing key recommendations that could help institutions when addressing both researcher and institutional RDM needs.

Published: December 2018

Many academic disciplines have very comprehensive standard for data publication and clear guidance from funding bodies and academic publishers. In other cases, whilst much good-quality general guidance exists, there is a lack of information available to researchers to help them decide which specific data elements should be shared. This is a particular issue for disciplines with very varied data types, such as engineering, and presents an unnecessary barrier to researchers wishing to meet funder expectations on data sharing. This article outlines a project to provide simple, visual, discipline-specific guidance on data publication, undertaken at the University of Bristol at the request of the Faculty of Engineering.

Authors: Senseney Megan , Dickson Eleanor , Namachchivaya Beth , LudÃ¤scher Bertram
Published: December 2018

Text data mining and analysis has emerged as a viable research method for scholars, following the growth of mass digitization, digital publishing, and scholarly interest in data re-use. Yet the texts that comprise datasets for analysis are frequently protected by copyright or other intellectual property rights that limit their access and use. This article discusses the role of libraries at the intersection of data mining and intellectual property, asserting that academic libraries are vital partners in enabling scholars to effectively incorporate text data mining into their research. We report on activities leading up to an IMLS-funded National Forum of stakeholders and discuss preliminary findings from a systematic literature review, as well as initial results of interviews with forum stakeholders. Emerging themes suggest the need for a multi-pronged distributed approach that includes a public campaign for building awareness and advocacy, development of best practice guides for library support services and training, and international efforts toward data standardization and copyright harmonization.

Sepsis dapat mengakibatkan hilangnya pertahanan mukosa usus sehingga menyebabkan translokasi produk bakteri ke dalam sirkulasi darah yang meningkatkan inflamasi pada organ lain.  Pemberian ketamin secara intraperitoneal diharapkan dapat menutunkan derajat inflamasi pada mukosa usus yang akan mengurangi terjadinya sepsis sehingga menurunkan morbiditas maupun mortalitas akibat sepsis.  Tujuan penelitian untuk mengetahui perbedaan derajat inflamasi dan pengaruh perbedaan waktu pemberian ketamin terhadap derajat inflamasi usus tikus.  Penelitian menggunakan metode experimental, dengan sampel hewan coba tikus putih rattus norvegicus dari galur wistar model sepsis menggunakan metode fecal induced peritonitis (FIP). Sampel dibagi menjadi enam kelompok perlakuan yaitu : kontrol negatif (A), kontrol positif (B), pemberian ketamin 5mg/kgbb pada jam ke-0 (C), ke-3 (D), ke-5 (E) dan pemberian berturut-turut pada jam ke 0,2,4 (F).  Analisa data menggunakan kruskal wallis dan regresi sederhana.  Hasil analisis kruskal wallis diperoleh nilai signifikansi sebesar 0,000 (p<0,05) yang menunjukkan ada perbedaan bermakna antar tiap kelompok perlakuan. Hasil uji regresi didapat nilai koefisien korelasi sebesar 0,730 dan nilai R2 yaitu 0,533 yang menunjukkan waktu pemberian ketamin berpengaruh positif terhadap derajat inflamasi mukosa usus tikus model sepsis.  Kesimpulan penelitian menunjukkan waktu pemberian ketamin berpengaruh positif terhadap derajat inflamasi mukosa usus tikus serta terdapat perbedaan derajat inflamasi pada setiap kelompok perlakuan pemberian ketamin Kata Kunci.

Efek Anti-Angiogenesis Ekstrak Kayu Secang Sebagai Terapi Adjuvant pada Diabetes Retinopati
Authors: Sa'diyah Isma Fadlilatus
Published: December 2018

Diabetes melitus merupakan kelompok penyakit metabolik yang ditandai oleh adanya peningkatan glukosa darah (hiperglikemi) akibat kegagalan tubuh dalam memproduksi insulin, kerja insulin yang tidak adekuat, atau keduanya. Hiperglikemi berkepanjangan pada diabetes kronik dapat menyebabkan kerusakan pada organ-organ penting seperti mata, ginjal, saraf, jantung, dan pembuluh darah. Kerurasakan organ yang paling sering terjadi adalah kebutaan mata pada pasien diabetes retinopati. Mekanisme terjadinya Diabetes Retinopati diduga sebagai akibat dari rangkaian proses inflamasi dan angiogenesis. Kayu Secang (Caesalpinea sappan) memiliki kandungan senyawa polifenol golongan flavonoid yang diketahui dapat menghambat terjadinya proses angiogenis. Proses angiogenesis diblok oleh inhibitor COX-2 yang diinduksi bFGF. COX-2 berperan pada proses angiogenesis melalui sintesis prostaglandin (PG). Prostaglandin berperan penting di dalam induksi VEGF. Penghambatan aktivitas COX-2 akan berakibat pada penghambatan angiogenesis. Oleh karena itu, efek anti-angiogenesis pada ekstrak Kayu Secang dapat digunakan sebagai terapi adjuvant pasien  diabetes retinopati.Kata kunci: Anti-angiogenesis, kayu secang, diabetes retinopati.

Pendahuluan Diabetes mellitus (DM) merupakan penyakit metabolik ditandai oleh hiperglikemia yang disebabkan berkurangnya produksi atau kerja insulin. DM dapat menyerang anak-anak. Kami melaporkan kasus hiperglikemia pada anak berusia 9 tahun dengan kadar C-peptida dalam batas normal.KasusAnak perempuanberusia 9 tahun, dibawa ke rumah sakit dikeluhkan lemah badan selama satu minggu. Pasien juga dikeluhkan sering kencing terutama di malam hari selama sebulan dan bekas kencing dirubung oleh semut. Pemeriksaan fisik dalam batas normal. Pemeriksaan laboratorium hari pertama : hemoglobin 14,8 g/dl, leukosit 9.860 sel/ul, trombosit 297.000 sel/ul, gula darah acak 328 mg/dl. Pemeriksaan hari kedua : gula darah puasa 274 mg/dl, gula darah 2 jam post prandial 370 mg/dl, dan glukosuria. Pemeriksaan C-Peptida 2,74 ng/ml (normal 1,1 – 4,4 ng/ml)PembahasanPada pasien anak ini ditemukan gejala khas diabetes yaitu fatigue dan poliuri. Pada pemeriksaan laboratorium didapatkan hiperglikemia. Sesuai dengan pedoman dari PERKENI pasien ini didiagnosis sebagai DM, yaitu tipe-1, dengan diferential diagnosis Maturity onset diabetes of the young (MODY) mengingat kadar C-peptida dalam batas normal.  DM tipe 1 disebabkan oleh karena kerusakan  sel beta pankreas akibat adanya autoantibodi terhadap pankreas. Sedangkan MODY disebabkan oleh mutasi genetik pada sel β pankreas sehingga terjadi inefektifitas produksi atau gangguan pelepasan insulin. Pemeriksaan tambahan seperti deteksi antibodi sel islet disarankan untuk menetapkan diagnosis DM tipe 1, dan pemeriksaan genetik untuk mendeteksi terjadinya mutasi sel β pankreas.SimpulanDiagnosis Type-1 Diabetes mellitus, dengan diagnosis banding Maturity onset diabetes of the young(MODY)Kata Kunci: hiperglikemia anak, C-peptida, Diabetes mellitus tipe-1, MODY

Published: December 2018

Penyakit fibrosis hati merupakan outcome dari semua jejas hati kronik, dengan manifestasi berupa jaringan parut pada area jejas, hilangnya arsitektur jaringan dan kegagalan fungsi hati. Stres oksidatif berperan penting dalam patogenesis fibrosis hati. Radikal bebas menyebabkan peroksidasi lipid membran sel dan menghasilkan  malondialdehid (MDA). Terapi antioksidan diduga memberikan efek menghambat progresifitas kerusakan hati. Biji jintan hitam (Nigella sativa Linn) mengandung antioksidan, antara lain berupa thymoquinon, asam linoleat dan asam oleat. Penelitian ini dilakukan  untuk membuktikan efek antioksidan ekstrak biji jintan hitam (Nigella sativa.Linn) terhadap tikus model fibrosis hati, dengan paramater berupa kadar kadar  Malondialdehid (MDA) hati. Metode penelitian menggunakan true experimental dengan post test only control group design. Sampel sebanyak 30 tikus yang dikelompokkan menjadi 5 kelompok. Kelompok normal diberi 1 ml/KgBB corn oil i.p. lalu dilanjutkan pemberian corn oil 1 ml/KgBB/hari p.o. Satu kelompok kontrol dan 3 kelompok perlakuan diinduksi CCl4 1ml/kgBB i.p 3 kali/minggu selama 8 minggu. Pada minggu ke-9, ketiga kelompok perlakuan diberi ekstrak biji jinten hitam dengan dosis berturut-turut 1,2; 2,4; dan 4,8 g/kgBB/hari selama 30 hari. Selanjutnya tikus dibedah, diambil jaringan hatinya dan dihitung kadar MDA hati. Pemberian ekstrak N. sativa dapat menurunkan kadar MDA hati (p=0,00) dan makin besar dosis N sativa, kadar MDA hati makin rendah (r = -0,614). Diduga  bioaktif ekstrak N. sativa meningkatkan aktivitas enzim antioksidan endogen dan menghambat peroksidasi lipid. Kata kunci : ekstrak N. sativa, MDA hati, tikus, fibrosis hati.
Influence of number magnitude in luxury brand names on consumer preference
Authors: Feng Wenting , Wang Tao , Rui Guo
Published: December 2018

In this study we built on scarcity theory, to conduct two experiments in which we investigated the influence of arbitrary numbers we inserted into brand names of luxury products. In Study 1 we recruited 68 consumers who were each assigned to one of two groups (small number or big number
for brand name), in order to test consumers’ preferences for luxury brands with names of different number magnitudes. The results revealed that a product with a small number in the brand name was received more favorably than was a product with a big number in the name. Scarcity mediated
the relationship between number magnitude and preference. In Study 2 we tested the moderating role of involvement. Number magnitude of the brand name influenced preference through scarcity when involvement was high but not when it was low. Thus, we found that numbers in the name of a luxury
brand arbitrarily impacted consumers’ perceptions of scarcity, which influenced their preference in regard to brand. This relationship was moderated by involvement. The results suggest that manufacturers of luxury brands should use a small number in their brand name, and should increase
the degree of consumer involvement to elevate consumer preference for the brand.
