Visual short-term memory for 3D shapes reveals similar properties to simple 2D features
Authors: Robitaille Joel , Emrich Stephen
Published: May 2019

In the past two decades, significant advances have been made to understand the psychophysical properties of visual short-term memory (VSTM). Most studies, however, make inferences based on memory for simple surface features of 2D shapes. Here, we examined the role of object complexity and dimensionality on the psychophysical properties of VSTM by comparing orientation memory for 2D lines and complex 3D objects in a delayed-response continuous report task, where memory load (Experiment 1) or axis of rotation (Experiment 2) was manipulated. In both experiments, our results demonstrate an overall cost of complexity that affected participants raw errors as well as their guess rate and response precision derived from mixture modelling. We also demonstrate that participants’ memory performance is correlated between stimulus types and that memory performance for both 2D and 3D shapes is better fit to the variable precision model of VSTM than to tested competing models. Interestingly, the ability to report complex objects is not consistent across axes of rotation. These results indicate that, despite the fact that VSTM shares similar properties for 2D and 3D shapes, VSTM is far from being a unitary process and is affected by stimulus properties such as complexity and dimensionality.
Examining the Impact of Working Memory Training and Transcranial Direct-current Stimulation on Monitoring for Color Targets in Dynamic Visual Displays
Authors: Muhl-Richardson Alex , Godwin Hayward , Garner Matt , Hadwin Julie , Liversedge Simon Paul , Donnelly Nick
Published: May 2019

Previous research has demonstrated that when monitoring dynamically changing visual displays for color targets, contingencies between targets and distractors facilitate predictive target detection, and elevated intolerance of uncertainty (IU) and lower verbal working memory capacity (WMC) are associated with a higher false alarm rate (see Muhl-Richardson et al., 2018). The present study examined whether search in this type of task improved following placebo-controlled adaptive dual n-back working memory (WM) training or transcranial direct-current stimulation (tDCS) of the dorsolateral prefrontal cortex. It also attempted to replicate previous findings but at a high level of target prevalence. The results demonstrate a new benefit to predictive target detection, which was associated with faster response times, and identify elevated IU and verbal WMC were as significant predictors of a higher hit rate. We provide an account of these effects in terms of response criterion and perceptual sensitivity. WM training and tDCS were found not to benefit performance on our dynamic search task (and a range other cognitive tasks), adding to a mixed literature on the efficacy of these techniques. The results nonetheless extend our understanding of dynamic search tasks and have implications for the selection of personnel in a variety of real-world scenarios.
Relationships between dispositional and experimentally elicited emotional reactivity, intensity, and perseveration
Authors: Boyes Mark Edward , Clarke Patrick , Hasking Penelope
Published: May 2019

Background: The Emotional Reactivity Intensity and Perseveration Scale (ERIPS) assesses dimensions of trait emotional reactivity, intensity, and perseveration. We aimed to further validate the ERIPS and determine whether these dimensions of trait emotion predict real-time responses to negatively and positively-valenced stimuli. Method: Undergraduate students (n=214) completed the ERIPS and viewed a sad and amusing movie clip. Participants provided sadness/amusement ratings at seven time-points pre and post viewing the clips. Results: Higher perseveration of trait negative and positive affect was associated with slower reductions in sadness and amusement ratings after viewing the clips. Higher trait positive reactivity was associated with a larger increase in amusement after viewing the amusing clip, and a faster return to baseline amusement levels. Trait negative reactivity and negative intensity were not associated with responses to the sad clip. Trait positive intensity was not associated with responses to the amusing clip. Conclusion: Although mixed, findings provide some validation of the ERIPS and indicate that, for reactivity and perseveration at least, trait affect may be associated with variability in state affect. Future research should consider mechanisms accounting for individual differences in emotional reactivity, intensity, and perseveration, as well as their potential utility in furthering understanding of emotional disorders.
Race and gender overlap to shape perception of children's faces
Authors: Lei Ryan , Rhodes Marjorie
Published: May 2019

Race and gender can be psychologically entangled, such that Black and masculinity are associated and Asian and femininity are associated. However. whether these associations (and the underlying processes) generalize to children’s faces remains unclear. The current work (N = 357) investigated the possibility that people overlap a target’s race and gender even when low-level physical cues are absent, using the important test case of children's faces. Study 1 found that White perceivers viewed Black boys’ faces as more masculine than White and Asian boys’ faces, controlling for low-level physiognomic cues; however, Asian girls’ faces were not perceived as more feminine. Studies 2A (White participants) and 2B (Black participants) replicated these results and investigated moderators. Although Black-masculine stereotypes emerged both implicitly (Study 1) and explicitly (Study 2A/2B), neither stereotype knowledge nor endorsement moderated the effects. Implications for face perception and for biases in adults’ perception and treatment of children are discussed.

De-Agentializing Data Practices: The Shifting Power of Metaphor in 1990s Discourses on Data Mining
Authors: Kerssens Niels
Published: May 2019

How do metaphor-driven representations of data mining in corporate media discourse affect understandings of data and data practices? This is, in short, the focal question of this article. Current media discourses of "Big Data" are characterized by a high degree of metaphorization and these metaphors play a key role in how we (mis)understand this ill-defined phenomenon. For example, media scholars Cornelius Puschman and Jean Burgess argue that associated metaphors of big data as a force of nature to be controlled and a form of nourishment/fuel to be consumed lead to a deceptive understanding of big data in terms of natural phenomena. These metaphors are misleading, they argue, as by evoking the image of big data as a force of nature their value is presented as a naturally given, while the fact that value and meaning are actually inscribed by analysis is obscured. This article aims to further deconstruct the representational politics of big data metaphors, directing specific attention to changes in the discursive—specifically metaphorical—framing of data practices in the 1990s, comparing academic discourses with corporate media discourses.
Ketimpangan dan Kontinuitas Patronase dalam Lintasan Sejarah: Menelusuri Sejarah Perubahan Agraria di Malang Selatan
Authors: Leksana Grace
Published: May 2019

Abstract: Opinions that perceive villages (desa) as solid entity, traditional, reservoir of labor and foodcrops, have been intensively criticized. On the contrary, villages are filled with social-political tension, class difference, and became areas where large conflicts in history also took place. This article develops the second argument, which tries to trace agrarian transformation through history: from the colonial period, independence and the New Order. By presenting a case study in South Malang, East Java, this article aim to show that village dynamics are controlled by patronage relation, where agrarian policies only benefited certain groups in the village. Historical analysis also shows how patronage relation persisted, although the state had changed. Violence that occurred in regime change did not necessarily transform the patronage relation in the village, instead strengthened it through the formation of new alliances. Agrarian policies that are going to be developed in the present should notice this power relation. The question of ‘who gets what’ should be continuously raised by agrarian studies experts and policy makers.Keywords: patronage relation, clientelism, class inequality, 1965 violence, colonial plantation, Malang-East JavaIntisari: Pandangan yang melihat desa sebagai entitas solid, tradisional, reservoir tenaga kerja dan pangan, telah banyak dikritik. Sebaliknya, desa dipenuhi dengan ketegangan sosial-politik, perbedaan kelas dan area dimana konflik-konflik besar dalam sejarah juga terjadi. Artikel ini mengembangkan pandangan kedua, dan berusaha menelusuri perubahan agraria dari masa ke masa: periode kolonial, kemerdekaan dan Orde Baru. Dengan mengambil studi kasus di Malang Selatan, Jawa Timur, artikel ini menunjukkan bahwa dinamika desa dikuasai oleh relasi patronase, sehingga kebijakan-kebijakan agraria hanya menguntungkan kelompok tertentu di desa. Analisa historis juga memperlihatkan bagaimana relasi patronase terus bertahan, meskipun negara (dalam hal ini sistem pemerintahan) telah berubah. Kekerasan yang terjadi dalam perubahan-perubahan rezim tidak mengubah relasi patron di tingkat desa, namun justru memperkuatnya dengan memunculkan aliansi-aliansi baru. Kebijakan-kebijakan agraria yang akan diambil pada masa kini seyogyanya memperhatikan relasi kuasa tersebut, sehingga pertanyaan ‘siapa mendapat apa’ harus kerap dikedepankan oleh para pegiat studi agraria dan para pengambil kebijakan.Kata kunci: relasi patronase, klientelisme, ketimpangan kelas, kekerasan 1965, perkebunan kolonial, Malang-Jawa Timur
Fretting Fatigue Cracking of a Crankshaft Flange from a Marine Diesel Engine
Authors: Chan P.C. , Thornley J.C.
Published: May 2019

A crankshaft flange from a marine diesel engine illustrated a less-common case of fretting-fatigue cracking. The crankshaft was from a main engine of a sea-going passenger/vehicle ferry. The afterface of the flange was bolted to the flange of a shaft driving the gearbox. Cracks observed were sharp, transgranular, and not associated with any decarburization or other microstructural anomalies in the steel. Cracking of this main engine crankshaft flange was very likely a consequence of fatigue cracking initiated at fretting damage. The cause of the fretting was from loosening of the bolts.

O nitrogênio aplicado às culturas pode alterar o comportamento das plantas daninhas. Assim, algumas espécies são favorecidas pela presença de adubos nitrogenados em doses elevadas, e outras se mostram indiferentes. A finalidade deste estudo foi verificar os efeitos de diferentes doses de nitrogênio na dinâmica de plantas daninhas da lavoura durante o ciclo da cultura do milho. Foi testada a influência de doses de nitrogênio sobre o crescimento do híbrido de milho AG8088 YGRR e na dinâmica das plantas daninhas. A comunidade de espécies infestantes da lavoura sofreu alterações na sua dinâmica em função do tempo de amostragem e inserção de técnicas de plantio, assim como o aumento da disponibilidade de nitrogênio na área. A similaridade foi menor quando se aplicou menores doses de nitrogênio (kg ha-1) e a testemunha antes do plantio.

Published: May 2019

A expansão do setor sucroalcooleiro suscitou preocupação quanto a questões que afetam a produtividade, tais como a presença de fitonematoides e as práticas de manejo cultural. O objetivo deste trabalho foi analisar a comunidade de nematoides do gênero Pratylenchus em cultivares de cana-de-açúcar plantados em solo submetido ou não à escarificação e ao aleiramento do palhiço residual da colheita. Foi conduzido experimento de campo em duas áreas, com e sem escarificação, nas quais foram plantadas 15 cultivares de cana-de-açúcar em subparcelas com e sem aleiramento do palhiço sobre as linhas de plantio. Anualmente, foram quantificados os nematoides do gênero Pratylenchus, no solo e nas raízes das plantas. Houve diferenças na densidade populacional do nematoide-das-lesões-radiculares em função do cultivar de cana-de-açúcar. O cultivar RB 92579 mostrou-se suscetível ao nematoide-das-lesões-radiculares. A não escarificação exerce limitação ao número de nematoides-das-lesões-radiculares, e a manutenção da palha sobre a superfície do solo em área total após a colheita de três safras não exerceu influência sobre a densidade populacional do nematoide-das-lesões-radiculares no solo ou nas raízes de diferentes cultivares de cana-de-açúcar. Após quatro anos de cultivo de cana-de-açúcar, a população de P. zeae prevaleceu sobre a de P. brachyurus.

Published: May 2019

rs1801133 is a single nucleotide polymorphism (SNP) located in the sequence of MTHFR on human chromosome 1. The alleles of this SNP affect the activity of the MTHFR enzyme. People bearing C/T genotype have 66% activity of MTHFR while people with T/T genotype have only 25% activity. These reduced activities of MTHFR cause homocysteinemia. There are several publications on the relationship between homocysteinemia and human diseases such as cardiovascular disease, neurological diseases, abnormal fetus, infertility and cancer. In this study, we built a molecular protocol for genotyping rs1801133 using real-time PCR HRM technique. This protocol could be used for diagnosis of molecular mechanism of homocysteinemia causing the mentoned above diseases as well as for the study of the relationship between rs1801133 and other human diseases. We successfully designed the primer pairs for genotyping and nucleotide sequencing rs1801133 by real-time PCR HRM and Sanger sequencing method. We also examined the optimal MgCl2 concentration for clear differentiation of three rs1801133 genotypes. Performance characteristics of the real-time PCR HRM protocol included of specificity, repeatability, reproducibility was evaluated and it showed good results. Comparison of genotyping results of rs1801133 between the realtime PCR HRM method and the Sanger nucleotide sequencing method showed good concordances. Finally, this real-time PCR HRM protocol for rs1801133 genotyping was applied on 100 human DNA samples to evaluate the clinical utility of the protocol.

An original approach to analytic canonical minimization of switching (Boolean) functions, which is based on the representation of Boolean functions (BF) as a function of one variable – the number of the set í of values of its arguments, is proposed. For this, using the Antje function, the dependence (in the form of formulas) of the values of each of n variables on the number í is established. To construct a minimal disjunctive or conjunctive normal form of the BF are repelled from the corresponding perfect forms. In this connection the need to describe the sequence of numbers of sets, on which the variables take the values 1 and 0, arises. The common terms of such sequences can be obtained using the formula for the common term of a numerical sequence in a representation through the finite differences of its members. Further the connection between the sum of the values of atoms (term) ó(í) and the numbers of their values is established. With the help of the values of ó(í) , the question of gluing the constituents of the unit or zero is solved. Threedimensional and four-dimensional cubes whose vertices are labeled with sigmas are depicted for a function of three and four variables, respectively. Since the necessary condition for gluing the constituents – the modulus of the difference between sigmas is equal to one – is not sufficient, the gluing criterion is used: the constituents of a unit or zero are glued if and only if the Gamming distance between two values of ó(í) is equal to one. The general order for gluing the constituent of a unit or zero on the basis of the described means is obtained. A matrix of size m× n , where m is the number of simple implicant or implicent, n is the number of sets, on which the BF unit or zero values takes, is used to build deadlock forms; they are not represented by letters, but by sets of ones and zeros that correspond to them. The proposed approach to minimizing BF is called the í -minimization method. An example of minimizing of BF of five variables, given by the numbers of the sets í of values of its arguments, on which it takes values equal to one, that is – with the property f = 1, is given. The possibility of using the í -minimization of BF in bases other than the basis (∧, ∨, ￣ ), and in the future – an application to the minimization of BF of integer mathematical programming is discussed.

Published: May 2019

Opening the car lock with the help of mobile based application is one of the great and important features that are missing from most of the cars sold globally. Although some cars support the remote starting functionality, dealers usually limit such feature to cars sold in certain regions such as the INDIA, US, etc. or to high-end models only. Additionally, manufacturers use short-range remote controllers, which limit the benefits of using the system. This idea will help bring this important feature to almost all cars, either old or new, and will add many important features such as GPS tracking in the system, all without compromising the safety and security aspects. The information is passed onto the central processing system which is in the form of the digital signals, the microcontroller unit reads the signal and sends it to the Global Positioning System (GPS) module and using the triangulation method, GPS module feeds the exact location in the form of latitude and longitude to the user's mobile. By reading the signals received by the mobile, one can trace the exact location of car. This project involves hardware and software parts construction and the integration of both parts to create the system. We succeed in achieving the objective and in fact, add another feature to the system which will initiates a call to the owner after sending the SMS. In the end of this project, we will document all the hardware and software development and provide a simulation model of the system. An interfacing mobile app is also connected to the microcontroller, which is in turn, connected to the system. Once, the vehicle is being stolen, the information is being used by the vehicle owner for further processing.

Cloud computing associate the computing and storage resources controlled by different operating systems to make available services such as large-scaled data storage and high performance computing to users. The benefits of low-cost, negligible management (from a user's perspective), and greater flexibility come with increased security concerns is one of the most crucial aspects among those prohibiting the wide-spread adoption of cloud computing. The data outsourced to a public cloud must need to be secured. This work gives Division and Replication of Data (DROPs) inside the Cloud for Optimal Performance and Security that judicially fragments user files into portions and replicates them at strategic places in the cloud. The division of a files into fragments is achieved based on a given consumer standards such that the individual fragments do not comprise any meaningful facts. The node separation is ensured by the means of the Grid Topology algorithm. To further improve the retrieval time, replicate fragments over the nodes that generate the highest read/write requests. The data encrypted using AES encryption algorithm. Duplication checking is implementing to provide efficient storage and time based access control for secure file access system.
United States versus Russia in the Era of Information Wars 2.0. Reflections on Dialogues from a Book
Authors: VASILIEV Vladimir
Published: May 2019

The debate between Russian TV journalist D.K. Kiselev and his American vis-a-vis N.V. Zlobin in the book “The Battle for Deeply Personal” (“Bitva za gluboko lichnoe”, Moscow, 2019) may well claim the status of a policy document of the new era of information warfare. It reflects basic patterns of ideological confrontation between Russia and the "collective West”; strengths and weaknesses of the platforms, on which broad sectors of Russian and American public have entered into "the battle for the deeply personal"; and an emerging discursive atmosphere in both countries. After analyzing this polemic and its context, the author concludes that the information war between Russia and the United States would be lengthy and in many ways would even surpass the ideological conflict of the Cold War in intensity and sharpness.

After
the declaration of independence from the Ottoman Empire in 1912, Albania faces
the big problem of the formation of a state with relevant institutions that
would guarantee the freedoms and rights of individuals. This paper, through
socio-historical analysis, aims to analyze the relationship of Albanians with
after the declaration of independence. This period is characterized by numerous
political changes experiencing revolutions, kingdom and, communism.

Albania
has always been under foreign rule and has not been able to develop a political
individuality in the direction of state leadership. This paper raises the main
thesis that exactly this continuation of the deprivation of the individuals by
the high political power elite continued in the communist period, which seems
to be the main cause of the lack of development of a political individual that
understands the duties and responsibilities pertaining to lawmakers.

The Manchester Driver Behaviour Questionnaire (DBQ) is widely used to measure driving styles and investigate the relationship between driving behaviour and accidents involvement. Recent evaluations of different population groups have taken place throughout the world, including countries in the Arabian Gulf. This study seeks to extend the application of the DBQ to Kuwait with its mix of native and expatriate drivers, by examining the relationships between speed-related behavior and accident involvement using a speed-related score (SRS). For this purpose, 536 respondents (425 Kuwaitis and 111 Non-Kuwaitis) were asked to complete a questionnaire based on the DBQ parameters as well as background information. The results showed that young Kuwaiti male drivers scored highest in most of the areas. Factor analysis resulted in four significant dimensions; speed-related violations, anger related violations, errors, and lapses. The study focused on the speed related violation score (SRS) as the dependent variable. The statistical analysis using ANOVA and t- test showed that there is a significant effect of such factors as accident involvement, age, gender, nationality, education level, driving experience and marital status. Some countermeasures to reduce accidents were identified focusing on those groups with higher SRS values.

Diseases caused by obstruction or rupture of vulnerable plaques in the arterial walls such as cardiovascular infarction or stroke are the leading cause of death in the world. In the present work, we developed human serum albumin nanoparticles loaded by physisorption with zinc phthalocyanine, TT1, mainly used for industrial application as near-infrared photosensitizer and compared these to HSA NPs loaded with the well-known silicone phthalocyanine (Pc4). The use of NIR light allows for better tissue penetration, while the use of nanoparticles permits high local concentrations. The particles were characterized and tested for toxicity and stability as well as for their potential use as a contrast agent and NIR photosensitizer for photodynamic therapy in cardiovascular disease. We focused on the distribution of the nanoparticles in RAW264.7 macrophage cells and atherosclerotic mice. The nanoparticles had an average size of 120 nm according to dynamic light scattering, good loading capacity for zinc phthalocyanine, and satisfying stability in 50% (v/v) fetal bovine serum for 8 hours and in an aqueous environment at 4°C for 4–6 weeks. Under light irradiation we found a high production of singlet oxygen and the products showed no dark toxicity in vitro with macrophages (the target cells in vulnerable plaques), but at a low g/mL nanoparticle concentration killed efficiently the macrophages upon LED illumination. Injection of the contrast agent in atherosclerotic mice led to a visible fluorescence signal of zinc phthalocyanine in the atherosclerotic plaque at 30 minutes and in the lungs with a fast clearance of the nanoparticles. Zinc phthalocyanine loaded human serum albumin nanoparticles present an interesting candidate for the visualization and potentially photodynamic treatment of macrophages in atherosclerotic plaques.

Actualmente el Hospital del Río – Hospirio S.A, es una institución privada que posee la mayor dimensión en edificación y capacidad para albergar pacientes en la Región Zona 6 de Ecuador, por tanto, los pacientes no solo se encuentran ubicados en el casco urbano de la ciudad de Cuenca, también existen en la zona rural de Cuenca, de la provincia del Azuay y otras provincias tales como Cañar, El Oro, Loja, Morona Santiago y Zamora Chinchipe. Posee instalaciones de primer orden, también cuenta con tecnología avanzada en la rama de medicina para brindar servicios de calidad, con responsabilidad y confianza. Sin embargo, la institución ha tratado de fomentar planes de gestión, para la entrada de pacientes al año, y obtener un flujo de ingresos/egresos, que permitan proyectar su gestión anual, pero, el porcentaje entre lo presupuestado y lo real ha tenido diferencias, obteniendo una baja entrada de pacientes, lo que conduce ajustar los gastos para el normal desenvolviendo de la institución. En virtud de ello, el propósito de esta investigación es identificar una propuesta de un plan de marketing que permitan incrementar la rentabilidad de las empresas del sector salud antes mencionado. La investigación es exploratoria, se utilizan datos cuantitativos y cualitativos, así como entrevistas y cuestionarios que permitan obtener información para establecer una propuesta. Los resultados presentados muestran que, con la estrategia de marketing, se puede incrementar la facturación en el año 2019 en un 20%, y aumentar el número de clientes en un 20%, para así obtener una utilidad y un crecimiento de la productividad para cubrir el mercado regional. Se concluye que el departamento de marketing de la institución no ha realizado un trabajo interno de difusión de funciones, información y promociones de sus servicios, por lo que deben trabajar en las estrategias de marketing a nivel interno.

La investigación a realizarse basa su importancia en el análisis profundo de los deportes colectivos con mayor incidencia y el rendimiento académico de los estudiantes de la Escuela Superior Naval. Las causas que producen un deficiente rendimiento académico de los deportistas al conformar una selección son muchas, pero entre las más comunes están: el no tener hábitos de estudio, irresponsabilidad académica, impuntualidad en la presentación de tareas, faltas consecutivas a clases de asignaturas con un mayor grado de dificultad. El descuido académico produce gran cantidad de repitencia y deserción estudiantil, todos estos resultados son expuestos y documentados en las tabulaciones realizadas de las encuestas.

Este artículo se propone mostrar, el valor patrimonial y representación simbólica de la arquitectura funeraria del Cementerio de Riobamba, a partir del análisis semiótico que tiene como objeto analizar los elementos históricos y patrimoniales identificados en mausoleos, nichos, tumbas y estructura arquitectónica. Para su análisis se utilizó el método semiótico que permitió identificar las características trascendentales de los elementos funerarios existentes en el campo santo objeto de estudio, y sociológico mediante la aplicación de cuestionarios dirigidos a especialistas y población para evidenciar los hábitos e interacciones socio-culturales. Se comprobó que el Cementerio de la ciudad de Riobamba, Ecuador cuenta con suficientes elementos semióticos que enriquecen este espacio público de interacción y construcción socio-cultural, donde se desarrollan procesos permanentes de comunicación simbólica explicitas de creencias y memorias colectivas generacionales, que permitirían proyectarse al desarrollo de turismo cultural debido a su gran potencial patrimonial y semiótico.
‘What a troupe family does’: Family as Transmission Narrative in the British Carnival Troupe Dancing Community
Authors: Wright Lucy
Published: May 2019

Troupe dancing, also known as ‘entertaining’, is a competitive formational dance performed by girls and women in the North of England and Wales. Demanding significant discipline and commitment to achieve the high levels of synchronisation expected for a successful routine, participants demonstrate a strong sense of community, frequently describing their teammates in terms that connote a familial relationship. Drawing on recent fieldwork with members of entertaining troupes in Staffordshire and Greater Manchester, this article outlines some of the ways in which the ‘troupe family’ is invoked at troupe dancing events, including End of Season Championships and Family Night celebrations, as well as the crucial role played by troupe families in providing a shared context for rites of passage associated with the life cycle, such as births, deaths and marriages. I suggest that appeals to the troupe family reflect the high status placed on familial identities in the working-class communities of which troupe dancing is a part. Further, I argue that the family constitutes a transmission narrative in contradistinction to the use of ‘tradition’ in the cognate English folk dance community. This article considers the implications of the family model, and its affordances in safeguarding carnival performance while embracing change and renewal.
Creative Pauses, Creative Energies: Mary Wigman's Eastward Turn
Authors: Kew Carole
Published: May 2019

Pauses, or resting positions, were a feature of Mary Wigman's dance. This enquiry discusses ways in which this feature is related to non-Western philosophies and techniques. In a process reminiscent of sacred dance, spectators were empowered to create their own mental images from within the space offered up by the pauses in Wigman's movement.
Heracleides
Authors: Almagor Eran
Published: May 2019

A great unknown is Heracleides of Cyme, the third Persica author who appears in Plutarch's corpus. The chapter begins with a literary interpretation of the references to Heracleides in Plutarch's works, proceeds to what we know of his Persica, and on the basis of what we can conjecture about Heracleides' work, it attempts to arrive at Plutarch's work method concerning this author. A discussion addresses a passage in Athenaeus' work, which deals with Timagoras. An excursus is included concerning Charon of Lampsacus and Plutarch's potential use of his lost Persica.
