About Artistry in Art
Authors:   Russian Academy of Arts, Krivtsun O.A. ,   State Institute for Art Studies
Published: October 2021

The phenomenon of artistry is investigated as a special expressive quality that manifests itself in different types and genres of art. The author comprehends the variations of the artistic principle as the most important ontological component of art, generating “meaning over meaning”, bringing a new dimension to the artistic content. The subject of the analysis is a variety of aesthetic profiles of artistry: from the dominance of virtuosity, playfulness, maestria, improvisation to the ability to paradoxically remove the antinomic tension of the elements of the art form. The value of the momentary artistic experience is studied simultaneously with the discovery of the facets of the inner, hidden artistry of the work. The peculiarities of the manifestation of artistry are investigated not only in ways of artistic expressiveness, but also in special forms of life creation.
Early Italian Art in the Works of Nicholas Roerich (1900s‐1910s)
Authors:   State Institute for Art Studies, Voytekunas V.A.
Published: October 2021

In the works created by Nicholas Roerich in the 1900s –1910s various cultural influences were synthesized. These were conditioned by the consistent pattern of the development of Russian art as well as by the individual preferences of the artist. The artistic heritage of old Italy became one of the strongest influences on Roerich and was interpreted by him in a particular way. The article examines the factors that determined Roerich’s interest in Italian art of the Middle Ages and the Early Re-r naissance and analyzes the experience of his trips to Italy in 1901 and 1906. The study of the style and methods of old masters significantly enriched Roerich’s means of expression and helped to establish his mature style.
Kursk Exhibitions of Kazimir Malevich: An Attempt of Reconstruction
Authors:   State Institute for Art Studies, Sokolova A.S.
Published: October 2021

The article focuses on the Kursk exhibitions with the participation of Kazimir S. Malevich, the history of their organization, exhibitors, reaction of critics. Notes in the local newspapers and magazines and preserved exhibition catalogs became the main sources of the research. This documents show that Malevich began to exhibit his works at the first exhibitions of the Kursk artistic community. Critical reviews give an idea of the titles of his paintings, the impression they made, or simply record participation. These texts can supplement the information of modern researchers about some facts of the artist’s biography. The paper is the first attempt to describe art exhibitions of 1910 and 1913 in details. Special attention in the text is paid to description of exhibition of the Association of Kursk Artists in 1910, where Malevich showed for the first time some paintings of “white series”, for example Rest (Otdyh), Bathing (Kupanie) and White Horse (Belaya loshad’). The exposition of “Cubists, Futurists and Ko”, which became part of the XIV exhibition of the Association of Kursk Artists, is introduced to the scientific audience for the first time. The author tried to find out the names of the exhibitors and the number of works, based on reviews in newspapers and photographs from the archive of Oleg Radin (Kursk). Malevich brought to Kursk at least 23 paintings. Some of these works were presented at the Oslinyj Hvost exhibition in Moscow in 1912, but the artist changed the composition of his paintings.
The Problem of Representing Trauma and the Role of Art in Witnessing Unspeakable Experience
Authors:   Lomonosov Moscow State University, Dremova E.N.
Published: October 2021

The article discusses approaches to the problem of traumatic experience and its representation, describes the discussions in trauma studies related to unpresentable and evidence, and the problems of the photographic image. The article reviews the theory of affect in connection with the analysis of the art of trauma. The author examines the meaning of dialogue and comes to the conclusion that art can become a place where it is possible to hear the voice of a wound, to share the pain of Another. The author analyzes the transitive role of art in the experience of the past on the example of conceptual artists — Doris Salcedo and Alfredo Jaar. Alfredo Jaar’s installations, which include documentary photographs, are analyzed from the point of view of the concept of punctum and correlate with the idea of affect.
Musicking and Islamic Law as a Problem of Methodology
Authors:   State Institute for Art Studies, Shamilli G.B.
Published: October 2021

The issue of music and Islamic law is considered in the aspect of the methodology due to the proper Arabic language picture of the world and mechanisms of theoretical thinking classical Arab-Muslim culture. The author clarifies that the procedure of inference in Islamic law did not concern music or musicians, but the actions of a person playing/listening music. On the grounds that legal power was epistemic, concentrated in the hands of private lawyers, there was no single center in Arab-Muslim culture from which the legislative decision regarding musicking/listening would extend to the entire Islamic world. The situation is different in the Russian Empire and the post-Soviet states, where, despite the external similarity with classical Islam, the attitude of a lawyer and a person who plays/listens music, for reasons of a cultural and historical nature, is built according to a hierarchical system of values and requires separate study without mechanically equating one historical phenomenon with another. It is shown that the contrarian dichotomy ‘permitted — forbidden — neutral’ appeared in modern science as a result of the universalist approach, did not take place in the legal field of the Arab-Muslim culture, which developed its own system of evaluating actions. The lawyer made a judgment, or ‘branch’, based on the basis-‘root’, which served as the textually fixed Koran and Sunnah, as well as the procedures of unanimous judgment and co-measurement, while the judgments themselves on the same fact could be contrastingly opposite, depending on the characteristics of the legal schools.
Tahrir as a Non‐Verbal Musical Element in the Art of Avaz
Authors:   Tchaikovsky Moscow State Conservatory, Nourshargh H.E.
Published: October 2021

The essay explores the phenomenon of tahrir, one of the most important elements of the avaz vocal art in Iranian classical music. As a hereditary avaz performer and an active concert soloist who has sung in this tradition for a number of years, the author bases his reasoning on the extensive practical experience of several generations of Iranian singers. As a result, instead of interpreting tahrir as a purely ornamental device, which is quite a widespread approach to this phenomenon, the author presents its detailed explanation as an extra-verbal multifunctional element in the evolvement of the avaz sonic texture, noting its deep semantic, psycho-emotional and form-structural meaning in each particular musical utterance. Audio files and music examples are attached to the essay.
Tamara Livanova (1909–1986) as a Reviewer of Verbal Texts
Authors:   State Institute for Art Studies, Petukhova S.A.
Published: October 2021

This article is devoted to T.N. Livanova’s peer review (1932–1986) and to the analysis of some of her responses to the colleagues’ texts. Mainly archival sources became the subject of study. Opening a new topic among studies of Russian musicology, this material also makes it possible to clarify many aspects of the biography of the Institute of Art History (now — the State Institute for Art Studies), where Livanova worked from the first days of its existence — in the Department of Music History (1944–1962) and in the Department of Western Classical Art (1960–1986).
Genre and Style Features of Dutch Symphonic Metal (on the Example of Epica)
Authors:   Tchaikovsky Moscow State Conservatory, Terentyev S.S.
Published: October 2021

The article is devoted to the work of the famous Dutch symphonic metal band Epica. The material highlights the genre and stylistic features of the music of this group, reveals the key features of the album concepts, determines the place of the band in the genre and style context of rock music in general and symphonic metal in particular. The genetic connection of symphonic met.al with progressive metal is revealed. On the example of Epica’s many-part compositions, which are based on various cultural sources and references to scientific theories, clothed in complex conceptual forms, the principle of “superhybridity” (J. Heiser’s term) is derived. As a formative principle of the group’s album triptych (The Quantum Enigma, The Holographic Principle, Omega), the concept of “metanarrative” (term by J.-F. Lyotard) is considered, the rehabilitation of which can be observed in the mainstream of the general processes of metamodernism in music. The author also refers to the developments of a number of researchers who have devoted their scientific works to the issues of terminology and typology of rock music.
The Voice of the Operating System in the Spike Jonze Film Her as a Hyperreal Object of Love
Authors:   S.A. Gerasimov All-Russian State Institute of Cinematography (VGIK), Mikheeva J.V.
Published: October 2021

The article raises the topic of “new sensuality” (“new sensualism”) as a phenomenon that revived the sentimentalism of the 1960s movie drama in the computer age and was embodied in a number of films of the last decade. In such films as Blade Runner 2049 (dir. Denis Villeneuve, 2017), Ex machina (dir. Alex Garland, 2015), I’m Here (dir. Spike Jonze, 2010) robots, replicant androids, and even laser projections act as men and women; and in the Spike Jonze film Her (2013), the main character, although a real man named Theodore, falls in love with the voice of the operating system Samantha, an affair with which becomes more real and valuable for him than anything he has previously experienced in relationships with real women. The plot of the film provides the basis for further practical and theoretical development of the film image of “akousmêtre”, a voice without a body. Digital technologies embodied in the film provide an opportunity to apply and rethink the concept of corporeality, which is relevant in phenomenological aesthetics, as well as to develop the meaning of synesthetic perception in the modern art space. At a new level of correlation between reality and virtuality, the ideas of dialogism that developed within the framework of philosophical anthropology in the twentieth century can be applied in the analysis of the film. Thus, the material of the presented films allows us to expand the art history discourse and raise a number of issues that are relevant not only for the screen arts of the 21st century, but also for people living in the world of digital technologies, but who have not lost the need for genuine human feelings.
Aesthetics of Early French Romanticism and Its Literary Aspects. Germaine de Stael
Authors:   Russian Academy of Sciences, Mankovskaya N.B.
Published: October 2021

The article reconstructs the early romantic philosophical aesthetics of Madame de Stael, which was embodied in her literary work. She made a significant contribution to the creation of the theory of romanticism, compared the romantic and classical types of creativity. De Stael was one of the first French romantics to use the term “romanticism”, define it and analyze from a philosophical and aesthetic point of view a number of key concepts for this new direction of artistic life: love, passion, enthusiasm, spirituality, sensitivity, reflection, self-reflection, melancholy, self-sacrifice, loneliness, alienation, imagination, inspiration, imagery, aesthetic pleasure, taste, talent, genius, ideal. She conceptualized the trend that would become prevalent in mature romanticism — a combination of the incongruous, sharp contrasts and tragic collisions of opposite principles — the sublime and the low, the beautiful and the ugly. De Stael attached particular importance to the national characteristics of artistic creativity, its rootedness in popular culture, and the influence of social institutions on art. She made a significant contribution to the development of aesthetic aspects of literary theory, put forward an innovative thesis about the “metaphysical” language that distinguishes the romantic style. The aesthetic vector of de Stael is directed to the future associated with the development of romantic art. All these ideas were reflected in her literary works.
Wondrous Light or “the World Inside Out” in the Author’s Animation by Valentin Olshvang
Authors:   S.A. Gerasimov All-Russian State Institute of Cinematography (VGIK), Zaytsev Z.Ya.
Published: October 2021

The article analyzes the work of an outstanding modern director of animated films, mainly author’s, Valentin Alekseyevich Olshvang on the example of his several films. The choice of films is dictated by their artistic and aesthetic, as well as technological component, where the director skillfully models the structure of his paintings, masterfully combining visual, sound and semantic series into a single whole. The subject of the study is a special interweaving of the visual and dramatic components of the director’s films, subordinated to the concept that can be described as “the world inside out”, in which the essence of love always carries destruction, and cannot be conflict-free. Through the analysis of the semantic layers of films, artistic and technological solutions of paintings, visual and expressive means used by Olschwang in the work, it was revealed that the most important aspect and factor of mediation for the release of creative imagination is the visual and technological component of the director’s creativity. It is proved the specificity of V. Olshvang’s works as characteristic for the author’s animation of the 90s of the last century — the beginning of this one. The analysis of the artistic and technological solutions of the selected paintings in the article is of particular interest for studying the work of the director, who uses various materials and methods of shooting in attempts to create a luminous, transparent image on the screen. The novelty of the research is in the consideration of V. Olshvang’s work as an original set of various visual and expressive techniques for the most accurate way of expressing the author’s idea.
First Russian Cyclists and Their Bicycles: Images in Literature and in Cinema
Authors:   State Institute for Art Studies, Saraskina L.I.
Published: October 2021

The paper, first, recapitulates the centuries-long history of designing and developing bicycles; in this history, inventors from many countries have taken part. As a result of the evolution of this wheeled transport, bicycles have become the most popular vehicles in cities as well as in villages; in many countries cycling has become the way of life. But, at the beginning, it was quite a problem to get accustomed to the sight of “riders on wheels”, especially if they were women. In capitals and in provincial towns, perceptions were quite different. The Russian cinema has documented the stages of introducing bicycles into the everyday life of the country, from the 1860s up to 1895. The feature films A Few Days from the Life of I.I. Oblomov (1979), The House of the Dead (1932), Man in a Shell (1939), as well as the retro-serial Anna, the Detective (2016–2020) have shown, with more or less details, how this and other European innovations were domesticated in Russia.
Photography of the World of Russian Rock in Modern Reflection
Authors:   State Institute for Art Studies, Yurgeneva A.L.
Published: October 2021

The article analyzes photographs of the world of underground music in the 1970s and 1980s. The author analyzes the images of musicians and notes their influence on the image of the heroes of Russian rock in modern cinema. Photography is considered as one of the main tools for the formation of the myth of Russian rock. Its actualization in the modern visual space in the form of exhibition projects and album editions is interpreted by taking into account the ideas of memorial culture. As a result of the research, the author reveals the adoption of the counterculture in the “big” history of the USSR and its inclusion in the nostalgic discourse about the Soviet past.
Balls of Count Etienne de Beaumont as an Element of the Social and Artistic Life of Paris in the 1920–1930s
Authors:   State Institute for Art Studies, Miroshnikova E.V. ,   The Pushkin State Museum of Fine Arts
Published: October 2021

In post-war Paris, there was an active search for a new philosophy of life and creativity — and at first it seemed that Dadaism could become such a basis for a new way of life. But the weak point of the Dadaists was that their concept of destruction and the foundations’ trampling did not offer anything in return besides an anarchy. Therefore, in parallel, the artists, actors and musicians, who were not attracted by the negative anarchist principles of Dadaism, tried to find some other prerequisites. One of the tendencies was the desire to present the game as the basis of the artistic process. Hence there is the aspiration for theatricality, performances, masks, the introduction of elements of theatricality into private life — as, for example, the famous thematic balls of Count Etienne de Beaumont, his theatrical enterprise “Les Soirées de Paris” in which J. Cocteau, E. Satie, V. Gross-Hugo, J. Hugo, P. Picasso and others participated. An article’ attempt is made to systematize the play approach to the creativity on the example of E. de Beaumont’s thematic balls in Paris in the 1920–1930s, to identify the characteristic features and differences of this phenomenon from the play activities of the past eras on the basis of “play” conceptions by M. Bakhtin, J. Huizinga and S. Kagan.

Published: October 2021

The authors of the article reflect on the processes of technical modernization of modern culture and on the modern reflection on the increasingly active introduction of new technologies in the field of art and art researches. There is an increasingly widespread nature of creativity and the inevitability of a long-term adaptation of a person to the results of his own creativity — which is another round of the eternal conflict between the creator and the creation. The article also examines the era of the 1920s, when art was intensively turning to the motives of machine, technical, and automatic world, giving rise to various interpretations of the interaction of man and machine, man and automaton. The theme continues with an appeal to the images of the robot child in American cinema of the second half of the 20th — beginning of the 21th century and to the vast field of modern science fiction art, which analyzes the current problems of civilization and, above all, communication systems — including the possibility of mass infections, the phenomenon of parasitic organisms, dystopian patterns of social relations. The scientific and artistic discourses are in close interaction.
INITIATIVES AND ROLE OF WOMEN SCIENTIST FORUMS WITH MENTORSHIP OPPORTUNITIES IN STEM
Authors: Konyeha S. , Agwam G. I. , Musa E. , Ngonadi I. V. , Afehomo A. C.
Published: October 2021

Women scientists are strategically positioned to drive the current initiatives for achieving targeted sustainable development goals (SDGs). Many women are celebrated today, who have made significant contributions in Science, Technology, Engineering and Mathematics (STEM), despite hurdles they have been faced with in their science careers. Engaging in normal scientific collaborations was difficult for some of them and simply impossible for others. They were not encouraged by the predominantly male environments of university and business worlds, barred from the communities in which male scientists met and conversed, these women in science struggled against discrimination based on gender. While many of these women have been nearly lost to history in a changing world, some achieved such pinnacles as the Nobel Prize by surmounting these hurdles. This paper investigates factors that inhibit women in science. To this end, a survey design based on random sampling technique using a questionnaire instrument was designed, to retrieve information from individuals engaged in science careers. The study population involved one hundred and fourteen post-graduate science students of the University of Benin. Data was collected and analyzed using SPSS 20.0 for descriptive and inferential statistics. The result revealed that females view mentorship as a very important factor towards their career progression in STEM, but 29% lacked mentors. 73% of the women were not aware of women scientist forums with mentorship opportunities. They were faced with the barrier of funding, lack of mentors and personally encountered gender bias amongst other barriers. From our result, it is evident that the role of mentors to mentees and women scientist initiatives alongside forums with mentoring activities, cooperation, networking and collaborative groups is needed to increase the participation of women and girls in STEM. It is recommended that mentoring forums and strategies should be adopted in schools and organizations to encourage girls and women in science.
MILP of multitask scheduling of geographically distributed maintenance tasks
Authors: Allaham Hamed , Dalalah Doraid
Published: October 2021

Due to its proactive impact on the serviceability of components in a system, preventive maintenance plays an important role particularly in systems of geographically spread infrastructure such as utilities networks in commercial buildings. What makes such systems differ from the classical schemes is the routing and technicians' travel times. Besides, maintenance in commercial buildings is characterized by its short tasks’ durations and spatial distribution within and between different buildings, a class of problems that has not been suitably investigated. Although it is not trivial to assign particular duties solely to multi-skilled teams under limited time and capacity constraints, the problem becomes more challenging when travel routes, durations and service levels are considered during the execution of the daily maintenance tasks. To address this problem, we propose a Mixed Integer Linear Programming Model that considers the above settings. The model exact solution recommends collaborative choices that include the number of maintenance teams, the selected tasks, routes, tasks schedules, all detailed to days and teams. The model will reduce the cost of labor, replacement parts, penalties on service levels and travel time. The optimization model has been tested using different maintenance scenarios taken from a real maintenance provider in the UAE. Using CPLEX solver, the findings demonstrate an inspiring time utilization, schedules of minimal routing and high service levels using a minimum number of teams. Different travel speeds of diverse assortment of tasks, durations and cost settings have been tested for further sensitivity analysis.
Integrated modeling of the peer-to-peer markets in the energy industry
Authors: Alvarez Gonzalo E.
Published: October 2021

Over time, the number of smart grids installed worldwide is gradually increasing. However, the major portion of the required electricity is still being produced by traditional large-scale and centralized power systems. The main requirement, then, is to study and develop mathematical methods that attend the integration between the two systems previously announced. In this paper, a novel model that addresses this issue is presented. The model minimizes the total operating cost of the large-scale system considering the participation of the smart grid as a dynamic entity, entailing a close relationship between both systems. This approach distinguishes the novel proposal from others that solve similar situations by taking into account the two systems in isolation. Besides, the models that represent the most common organizational structures of the smart grids are also presented in this paper. They are needed to develop the integrated model. Many similar problems in the literature are solved by implementing decomposition techniques, which might obtain a local optimum different from the global one. By contrast, problems with this proposal are solved by using mixed-integer linear programming models that ensure the reaching of a global optimum. The real test case is the integrated Argentine large-scale system and the Armstrong smart grid. Results indicate that the novel model can reach solutions that are 5% lower in comparison with the traditional techniques of considering in isolation. Efficient CPU times enable the possibility of promptly obtaining solutions if there is any change in the parameters. In addition, other benefits, apart from the economical reductions, are also achieved. Operating information closer to the reality of both systems is obtained because it considers the effects of the smart grid in large-scale system solving.
A hybrid approach of simulation and metaheuristic for the polyhedra packing problem
Authors: Pantoja-Benavides Germán Fernando , Álvarez-Martínez David
Published: October 2021

This document presents a simulation-based method for the polyhedra packing problem (PPP). This problem refers to packing a set of irregular polyhedra (convex and concave) into a cuboid with the objective of minimizing the cuboid’s volume, considering non-overlapping and containment constraints. The PPP has applications in additive manufacturing and packing situations where volume is at a premium. The proposed approach uses Unity® as the simulation environment and considers nine intensification and two diversification movements. The intensification movements induce the items within the cuboid to form packing patterns allowing the cuboid to decrease its size with the help of gravity-like accelerations. On the other hand, the diversification movements are classic transition operators such as removal and filling of pieces and enlargement of the container, which allow searching on different solution neighborhoods. All simulated movements were hybridized with a probabilistic tabu search. The proposed methodology (with and without the hybridization) was compared by benchmarking with all previous works solving the PPP with irregular items. Results show that satisfactory solutions were reached in a short time; even a few published results were improved.
Cockpit crew pairing Pareto optimisation in a budget airline
Authors: Chutima Parames , Krisanaphan Nicha
Published: October 2021

Crew pairing is the primary cost checkpoint in airline crew scheduling. Because the crew cost comes second after the fuel cost, a substantial cost saving can be gained from effective crew pairing. In this paper, the cockpit crew pairing problem (CCPP) of a budget airline was studied. Unlike the conventional CCPP that focuses solely on the cost component, many more objectives deemed to be no less important than cost minimisation were also taken into consideration. The adaptive non-dominated sorting differential algorithm III (ANSDE III) was proposed to optimise the CCPP against many objectives simultaneously. The performance of ANSDE III was compared against the NSGA III, MOEA/D, and MODE algorithms under several Pareto optimal measurements, where ANSDE III outperformed the others in every metric.
Discounted costs and obsolescence with the Joint replenishment problem
Authors: Afonso Ricardo , Godinho Pedro , Costa João Paulo
Published: October 2021

Real life inventory lot sizing problems are frequently challenged with the need to order different types of items within the same batch. The Joint Replenishment Problem (JRP) addresses this setting of coordinated ordering by minimizing the total cost, composed of ordering (or setup) costs and holding costs, while satisfying the demand. The complexity of this problem increases when some or all item types are prone to obsolescence. In fact, the items may experience an abrupt decline in demand because they are no longer needed, due to rapid advancements in technology, going out of fashion, or ceasing to be economically viable. This article proposes an extension of the Joint Replenishment Problem (JRP) where the items may suddenly become obsolete at some time in the future. The model assumes constant demand and the items’ lifetimes follow independent negative exponential distributions. The optimization process considers the time value of money by using the expected discounted total cost as the minimization criterion. The proposed model was applied to some test cases, and sensitivity analyses were performed, in order to assess the impact of obsolescence on the ordering policy. The increase in the obsolescence risk, through the progressive increase of the obsolescence rates of the item types, determines smaller lot sizes on the ordering policy. The increase in the discount rate causes smaller quantities to be ordered as well.
An algorithm for a no-wait flowshop scheduling problem for minimizing total tardiness with a constraint on total completion time
Authors: Allahverdi Ali , Aydilek Harun , Aydilek Asiye
Published: October 2021

We consider a no-wait m-machine flowshop scheduling problem which is common in different manufacturing industries such as steel, pharmaceutical, and chemical. The objective is to minimize total tardiness since it minimizes penalty costs and loss of customer goodwill. We also consider the performance measure of total completion time which is significant in environments where reducing holding cost is important. We consider both performance measures with the objective of minimizing total tardiness subject to the constraint that total completion time is bounded. Given that the problem is NP-hard, we propose an algorithm. We conduct extensive computational experiments to compare the performance of the proposed algorithm with those of three well performing benchmark algorithms in the literature. Computational results indicate that the proposed algorithm reduces the error of the best existing benchmark algorithm by 88% under the same CPU times. The results are confirmed by extensive statistical analysis. Specifically, ANOVA analysis is conducted to justify the difference between the performances of the algorithms, and a test of hypothesis is performed to justify that the proposed algorithm is significantly better than the best existing benchmark algorithm with a significance level of 0.01.
Optimization of Bayesian repetitive group sampling plan for quality determination in Pharmaceutical products and related materials
Authors: Kaviyarasu Velappan , Sivakumar Palanisamy
Published: October 2021

Sampling plans are extensively used in pharmaceutical industries to test drugs or other related materials to ensure that they are safe and consistent. A sampling plan can help to determine the quality of products, to monitor the goodness of materials and to validate the yields whether it is free from defects or not. If the manufacturing process is precisely aligned, the occurrence of defects will be an unusual occasion and will result in an excess number of zeros (no defects) during the sampling inspection. The Zero Inflated Poisson (ZIP) distribution is studied for the given scenario, which helps the management to take a precise decision about the lot and it can certainly reduce the error rate than the regular Poisson model. The Bayesian methodology is a more appropriate statistical procedure for reaching a good decision if the previous knowledge is available concerning the production process. This article proposed a new design of the Bayesian Repetitive Group Sampling plan based on Zero Inflated Poisson distribution for the quality assurance in pharmaceutical products and related materials. This plan is studied through the Gamma-Zero Inflated Poisson (G-ZIP) model to safeguard both the producer and consumer by minimizing the Average Sample Number. Necessary tables and figures are constructed for the selection of optimal plan parameters and suitable illustrations are provided that are applicable for pharmaceutical industries.
Contract design for the fourth party logistics considering tardiness risk
Authors: Wang Hongyan , Huang Min , Wang Hongfeng , Feng Xuehao , Zhou Yanjie
Published: October 2021

Nowadays, tardiness has become a significant risk in the logistics industry. To address this problem, we introduce the tardiness risk index to quantify both the magnitude of the tardiness risk and the maximum probability of tardiness occurring. In this paper, we investigate the contract design problem with the tardiness risk index to mitigate the tardiness risk when a fourth-party logistics company (4PL) delegates the delivery task of a client to a third-party logistics company (3PL). Specifically, the contracts are designed in a decentralized system with information symmetry and information asymmetry when 3PL is risk neutral and risk averse. Furthermore, the incentive problems demonstrated that the 3PL is encouraged to make the optimal effort for delivery and the 4PL determines the optimal fixed payment and penalty coefficient. Through analyzing the experimental simulation results, we can find that the contract can effectively mitigate the tardiness risk and the maximum probability of risk occurrence.
The Influence of Non-UV Wavelengths of Light on Skin: What Constitutes a Healthy Level of Exposure Particularly in Relation to Melanoma?
Authors: Smith David John Mackay
Published: October 2021

We live with solar radiation from birth to death and have since the emergence of life on earth. Why then does skin cancer diagnosis remain so disturbingly high in Australia? Part of the problem is the majority of the population are of Northern European ancestry. Moving closer to the equator on mass we have carried with us a polymorphic melanocortin receptor gene on our melanocytes responsible for an incomplete tanning response. We attempt to protect ourselves with clothing and creams or remain indoors but this does not seem to be stemming the tide. Occupation, recreation or both drive us outside and into the sun. We need to be more successful at negotiating the potentially harmful effects by relooking at solar radiation and instead of focusing on the most harmful wavelengths look at the overall effect of the whole spectrum. We also need to re-examine our behaviour and exposure patterns. Prolonged periods indoors under artificial light punctuated with short bursts of intense irradiation is maladaptive. Creams aim to block the ultraviolet component, ignoring 90% of solar photons, the protective effect is incomplete, yet their use encourages more prolonged exposure. Protective behaviours are necessary for the most sensitive skin types but they are still at risk. For the rest of the population evolutionarily developed natural protective mechanisms can be employed. Regular moderate sun exposure, below the burn threshold, ideally aimed at early morning or late afternoon. Augmented with clothing, hats and creams with an appreciation of the incomplete protective effect of these measures.

We present a stepwise approach to estimate high dimensional Gaussian graphicalmodels. We exploit the relation between the partial correlation coefficientsand the distribution of the prediction errors, and parametrize the model in termsof the Pearson correlation coefficients between the prediction errors of the nodes’best linear predictors. We propose a novel stepwise algorithm for detecting pairsof conditionally dependent variables. We compare the proposed algorithm withexisting methods including graphical lasso (Glasso), constrained `l1-minimization(CLIME) and equivalent partial correlation (EPC), via simulation studies andreal life applications. In our simulation study we consider several model settingsand report the results using different performance measures that look at desirablefeatures of the recovered graph.
A Conceptual Framework for Describing the Role of Employer Branding, Person-Organization Fit and Employee Engagement in Shaping Organizational Citizenship Behavior
Authors: Lary Alaa Ibrahim , Omar Rosmini
Published: October 2021

The small and medium-sized enterprises (SME) play a fundamental role in providing job opportunities and supporting national economy. Therefore, it is essential to increase SMEs’ contributions to the economy by examining the factors that positively impact performance. As one of the main obstacles that hinder SMEs’ performance is workforce-related, then organizational citizenship behavior (OCB) can contribute to performance improvement. Consequently, the current research’s concern is to identify factors that are associated with employee OCB. To this end, employer branding, employee engagement and person-organization fit are proposed as antecedents of the OCB. This study contributes to the literature by identifying determinants of OCB and providing a framework that improves OCB.
Formando planificadores latinoamericanos. Estructuras institucionales en Uruguay y Chile en la década del sesenta
Authors: Monti Alejandra
Published: October 2021

El presente artículo indaga acerca de las formas que adquirió en América Latina —particularmente en Uruguay y Chile— la discusión en torno a la formación de profesionales desde un enfoque integral en el campo de la planificación urbana y regional, en el contexto de las políticas desarrollistas de mediados de la década del sesenta. Analizando comparativamente la actividad del Instituto de Teoría de la Arquitectura y Urbanismo en Uruguay y el Comité Interdisciplinario de Desarrollo Urbano en Chile, a través de fuentes primarias institucionales y fuentes secundarias referidas a la historia de la disciplina en la región, se avanza en la identificación de los vínculos entre Estado, universidad y técnica. Desde esta perspectiva, se reconoce que las dos experiencias actuaron como espacios de formación de cuerpos profesionales capaces de dar respuesta a las nuevas necesidades de los Estados, tanto en términos de ideas como de gestión del territorio, entendido este a partir de su rol como variable de las políticas desarrollistas para orientar el equilibrio nacional.
Planificación urbana y participación en el estado de México
Authors: Gutiérrez-Chaparro Juan José , Márquez-González Laura Karla
Published: October 2021

En medio de la coyuntura definida por las directrices de la política internacional en materia de asentamientos humanos y ordenamiento territorial, en diciembre de 2019 fue publicado el Plan estatal de desarrollo urbano del estado de México (Gobierno del estado de México, [GEM], 2018a). Localizado en el centro del país, el estado de México es la entidad más poblada con alrededor de 17 millones de habitantes y una de las más dinámicas económicamente. En el discurso formal, se asume que este plan es resultado de la instrumentación de la Nueva Agenda Urbana, sin embargo, partimos del supuesto de que la actualidad instrumental y la política urbana son efectivamente discursivas y que, en los hechos, el plan se caracteriza por su obsolescencia, pero especialmente por su falta de legitimidad. Así planteado, nuestro objetivo es evaluarlo desde una perspectiva metodológica y normativa con énfasis en la participación. Examinamos evidencias de forma documental a la vez que, desde la observación no participante, documentamos el proceso de consulta del plan. Se esperaba un avanzado ejercicio participativo considerando la complejidad urbana del estado de México y la coyuntura de cambio, pero no fue así, en su lugar reunimos evidencias que demuestran la ausencia de consensos y la resistencia al cambio. Tanto los resultados de los foros de consulta como sus repercusiones hacia el proceso en conjunto se cuentan entre los principales hallazgos.
Percepción social de la inseguridad y apropiación simbólica del espacio en la periferia de la metrópolis de México
Authors: Castillo Oropeza Oscar , García Morales Ángel
Published: October 2021

En este artículo se analiza cómo la percepción social de la inseguridad y la apropiación simbólica del espacio son procesos interrelacionados en la experiencia cotidiana de los sujetos, a partir de un estudio de caso en el Fraccionamiento Villas de la Laguna, Zumpango de Ocampo, en la periferia de la metrópolis de México. En la primera parte, se definen los conceptos de percepción social de la inseguridad y apropiación simbólica del espacio. Posteriormente, se discute sobre las causas de fondo del proceso de urbanización en ese lugar, sus particularidades y consecuencias, como es la presencia de la inseguridad y sus efectos subjetivos en los habitantes. La principal conclusión es que los sujetos que habitan ese lugar lo definen como inseguro y peligroso, por medio del uso de diferentes dispositivos como el cuerpo y los sentidos, los cuales se encuentran ligados con sus diversas formas de vivir el espacio a través de los rumores y el caminar. Finalmente, para dar cuenta de ello, se implementó una estrategia metodológica que consistió en observaciones de campo, entrevistas semiestructuradas a informantes clave, recuperación de datos estadísticos oficiales, revisión de notas de periódico, fotografías y sistemas de información geográfica, con la finalidad de aportar otros elementos para la reflexión, el debate y la toma de decisiones.
Análisis del espacio público frente a la pandemia en una urbanización informal argentina
Authors: Rodríguez Tarducci Rocío , Birche Mariana , Cortizo Daniela
Published: October 2021

En urbanizaciones informales, los espacios públicos son de suma importancia para la recreación, socialización e incluso también para la economía de estas comunidades. Ante la amenaza del COVID-19, el funcionamiento, los requerimientos y características del espacio público se ponen bajo la lupa, y resulta interesante pensar en las nuevas realidades derivadas de la pandemia. El objetivo del trabajo es reconocer qué características presentan los espacios públicos en las urbanizaciones informales y cómo deberían adecuarse, contemplando los requerimientos de sus habitantes, en el contexto de la pandemia COVID-19 y de cara al futuro. Para tal fin, se analiza el caso del barrio Puente de Fierro, ubicado en la periferia sureste del Partido de La Plata, Buenos Aires, Argentina. El abordaje metodológico consiste en el análisis de distintas categorías de espacios públicos. Los resultados de la investigación permiten corroborar, a partir del caso de estudio, que estos espacios resultan indispensables para el quehacer diario de sus habitantes. Ante la escasez y el deterioro se plantean nuevos desafíos, atendiendo a la intervención y adecuación de espacios que contemplen los requerimientos de la población en situación de vulnerabilidad.

La seguridad nacional en el sistema normativo actual chileno: Análisis en relación con las recientes oportunidades en que ha sido invocada
Authors: Martinic Cynthia Alejandra
Published: October 2021

La seguridad nacional, al ser un concepto ambiguo y tradicionalmente indeterminado, se ha utilizado en algunas ocasiones como factor para imponer determinados intereses políticos a la población, para justificar violaciones a los derechos humanos y últimamente para frenar los cambios en curso. Este artículo desarrolla someramente el tratamiento doctrinal y que el sistema internacional de los derechos humanos y otros acuerdos internacionales le han dado al concepto de seguridad nacional y sus alcances. Se exponen además tres ejemplos recientes en Chile en que se ha invocado la seguridad nacional o la inteligencia estatal como su herramienta, con el objeto final de establecer la necesidad de que, con miras a una nueva constitución, se elabore y delimite un concepto de seguridad nacional que atienda las nuevas amenazas existentes, desmilitarice su tratamiento y control y tenga como centro la dignidad humana.
