Diseño y validación de un instrumento para analizar el sistema de evaluación de las guías docentes universitarias en la formación inicial del profesorado (IASEG)
Authors: Romero-Martín María Rosario , Asún Dieste Sonia , Chivite Izco Miguel
Published: September 2020

Resumen:La evaluación formativa ha sido considerada como un elemento altamente coherente en el diseño de programas docentes universitarios basados en competencias. A partir de esta concepción formativa de la evaluación, el objetivo de este estudio se ha centrado en alcanzar un consenso de expertos para crear y validar un instrumento que permita valorar la eficacia de los sistemas de evaluación, presentes en las guías universitarias de la formación inicial del profesorado, para detectar el grado de adquisición de competencias docentes. Se utilizó para ello el método Delphi. Inicialmente, a partir de una exhaustiva revisión bibliográfica y de un ciclo de juicios de expertos, se identificaron las dimensiones y elementos constitutivos de los sistemas de evaluación, creándose un primer instrumento para el análisis de los mismos. Posteriormente, el instrumento se envió en dos rondas al grupo de expertos, mediante el que se llegó a consensos óptimos sobre el nivel de eficacia de los distintos elementos de los sistemas de evaluación para valorar competencias docentes. Finalmente, se efectuó una prueba piloto en la que tres evaluadores analizaron una muestra de guías docentes aplicando el instrumento. El grado de acuerdo entre expertos para la delimitación de los ítems y dimensiones, la compactibilidad hallada durante el análisis Delphi y la concordancia de evaluadores en la prueba piloto, arrojaron datos que permitieron concluir la validez del instrumento diseñado.

Tras los pasos de Soulèvements
Authors: Montes Sánchez Lucía
Published: September 2020

En este artículo, me propongo pensar la tarea de Georges Didi-Huberman como historiador del arte y teórico de la imagen de la mano de su faceta como comisario de exposiciones, a la luz de su última propuesta de exposición, a saber: el dispositivo trazado en torno al fenómeno de la resistencia social y el levantamiento popular, que se ha titulado originalmente Soulèvements y ha sido producido mayoritariamente por la Galería Jeu de Paume de París. Para ello, se explorará en sus textos qué le exige el autor a toda práctica que pretenda "hacer sensible" las conmociones experimentadas por los seres humanos, para ver de qué manera traduce esto en los montajes expositivos sucesivos que han conformado el proyecto Soulèvements. Seguidamente, analizaremos las implicaciones políticas de su migración y su condición de apertura, y reconstruiremos la fábula antropológica sobre la que se construye el recorrido expositivo y que dará cuenta, como se justificará más adelante, de la complejidad de la temporalidad de la revuelta en esta propuesta.
La cultura como imaginación social
Authors: Dembeck Till
Published: September 2020

El presente trabajo propone comprender la cultura como imaginación social. De manera análoga al concepto de la facultad de la imaginación que en la filosofía transcendental designa la capacidad de la conciencia de constituir rasgos repetibles y por tanto significativos, la cultura puede definirse como un conjunto de mecanismos que proporcionan significación a la sociedad. El modelo propuesto insiste en la diferencia entre conciencia y sociedad al caracterizar la cultura como un momento de su unión estructural. La contingencia de cualquier determinación de la significación implica la autonomía de la cultura frente a cualquier pretensión de soberanía individual o social y permite que la cultura, entendida en este sentido, aparezca como la base de la comprensión que siempre socava cualquier delimitación, por ejemplo en términos de conceptos de identidad.

A ellas hay que añadir otro aliciente más que presenta este volumen: cuenta con un texto inédito de su firma y una larga entrevista a modo de conversación con los profesores Gabriel Cabello Padial e Irene Valle Corpas, donde el francés comenta algunos pasos importantes de su trayectoria, nos habla de sus intereses más recientes o da referencias significativas sobre su particular modo de trabajar con y a partir de las imágenes.
Öffentlichkeit – Veröffentlichen – Öffentlichkeit Herstellen: Einleitung
Authors: Frömming Gesa , Stanitzek Georg
Published: September 2020

Recent developments in digital network communication suggest that the distinction between public and private has become precarious. This situation warrants a closer look at the infrastructures and practices of making things public. What can we learn about the public sphere by studying how, exactly, it is being produced? What constitutes the threshold between public and private, and how does one pass it? Which medial, social, rhetorical, and political practices and semantics, which modes of cooperation are involved in acts of publishing? The introduction critically re-examines 20th-century theories of the public sphere in light of these questions.
Structure and Aim in Socratic and Sophistic Method
Authors: Rodriguez Evan
Published: September 2020

I begin this paper with a puzzle: why is Plato’s Parmenides replete with references to Gorgias? While the Eleatic heritage and themes in the dialogue are clear, it is less clear what the point would be of alluding to a well-known sophist. I suggest that the answer has to do with the similarities in the underlying methods employed by both Plato and Gorgias. These similarities, as well as Plato’s recognition of them, suggest that he owes a more significant philosophical and methodological debt to sophists like Gorgias than is often assumed. Further evidence from Plato and Xenophon suggest that Socrates used this very same method, which I call ‘exploring both sides’. I distinguish this Socratic method and its sophistic counterpart in terms of structure, internal aim, and external aim. Doing so allows for a more nuanced understanding of their similarities and differences. It also challenges the outsized role that popular caricatures of philosophical and sophistic method have had on our understanding of their relationship.
Reading the Nicomachean Ethics as an Investigation
Authors: Schuh Guy
Published: September 2020

Aristotle tells us that the Nicomachean Ethics is an “inquiry” and an “investigation” (methodos and zētēsis). This paper focuses on an under-appreciated way that the work is investigative: its employment of an exploratory investigative strategy—that is, its frequent positing of, and later revision or even rejection of, merely preliminary positions. Though this may seem like a small point, this aspect of the work’s methodology has important consequences for how we should read it—specifically, we should be open to the possibility that some contradictions in the text are the result of his employment of this investigative strategy. In the paper, I describe this investigative strategy, discuss what motivates Aristotle to employ it in the work, and go through three contradictions that are plausibly identified as examples of its use—specifically, his claims that courageous people do and do not fear death, that friendship is and is not mutually recognized goodwill, and that virtuous people do and do not choose noble actions for their own sake.
Aristotle, Isocrates, and Philosophical Progress
Authors: Walker Matthew D.
Published: September 2020

In fragments of the lost Protrepticus, preserved in Iamblichus, Aristotle responds to Isocrates’ worries about the excessive demandingness of theoretical philosophy. Contrary to Isocrates, Aristotle holds that such philosophy is generally feasible for human beings. In defense of this claim, Aristotle offers the progress argument, which appeals to early Greek philosophers’ rapid success in attaining exact understanding. In this paper, I explore and evaluate this argument. After making clarificatory exegetical points, I examine the argument’s premises in light of pressing worries that the argument reasonably faces in its immediate intellectual context, the dispute between Isocrates and Aristotle. I also relate the argument to modern concerns about philosophical progress. I contend that the argument withstands these worries, and thereby constitutes a reasonable Aristotelian response to the Isocratean challenge.

Gelişen teknoloji ve küreselleşmeyle değişen toplum yapısına uyum sağlayan kentler inovasyon süreci içinde etkileşim sağlanan, yeni fikirlerin ortaya çıktığı ve bilginin yayıldığı açık sistemler olarak ortaya çıkmaktadır. Yapay zekanın, robotların ve bilişim sistemlerinin günlük hayatımızda yer aldığı, her gün bilinmeyenle ilgili yeni bilgilere eriştiğimiz çağda, dünya nüfusunun yarısı kentlerde yaşamakta ve kent sakinleri dünyanın doğal kaynaklarının dörtte üçünden fazlasını tüketmektedir. Hızlı kentleşme ve nüfus artışı sorunları beraberinde getirmekte ve kentlerin yaşanabilir olma özelliklerini kaybetmelerine neden olmaktadır. Hızlı kentleşmenin bir krize dönüşmesini engellemek için kentleri yenilikçi bir yaklaşımla donatmak ve yönetmek çağın gerekliliğidir. Bu gerekliliğin sonucunda, kentsel inovasyon hızlı kentleşmenin ortaya çıkardığı karışıklığı ve sorunları çözmenin bir yolu olarak ortaya çıkmaktadır. Makale kapsamında, 2018 yılı baz alınarak elde edilen kentsel inovasyon göstergelerinden araştırma-geliştirme faaliyet göstergelerinin ve çevresel faaliyet göstergelerinin kentleşmeyi olumsuz yönde etkilerken; sağlığa yapılan yatırımları gösteren faaliyetlerin, altyapı faaliyet göstergelerinin ve bireysel yatırım-tasarruf göstergelerinin kentleşme üzerinde olumlu yönde etkisi olduğu belirlenmiştir.
The Anthropocene Operating Space for antimicrobial resistance: tipping points in treatability of priority pathogens
Authors: Graells Tiscar , Heinzel Christine , Jorgensen Peter Sogaard
Published: September 2020

Evolution of antimicrobial resistance, especially antibiotic resistance, results from complex dynamics between microorganisms, stressors and the environment itself, where non-linear dynamics are present with unpredictable impacts on treatability, and therefore, on society. The Anthropocene Operating Space for Antimicrobial Resistance is a recent framework for risk-assessment of tipping-points in treatability by combining information about the level of resistance and the effects of available antimicrobials. Here, we develop this framework at an increased level of resolution and extent compared to previous analysis adding three sub-zones to the original three zone framework and applying it to 20 priority pathogens, constituting its first application at the pathogen level, including fungal pathogens. In doing so, we also provide updated definitions of each zone and sub-zone together with an overview of mechanisms and contexts contributing to treatability of tipping point risks. We find that 7 out of 20 assessed priority pathogens (6 out of 11 Gram-negative bacteria) are in the zone of highest risk where widespread tipping points in treatability are most likely (surpassed zone). Namely, Acinetobacter spp., Pseudomonas spp., Enterobacteriaceae (Escherichia coli and Klebsiella pneumoniae), Neisseria gonorrhoeae and the yeast Candida auris are those assessed exceeding our current resources. Meanwhile, Mycobacterium tuberculosis, Clostridioides difficile, Staphylococcus aureus, Enterococcus and Salmonella are classified at very high risk of crossing the tipping point in treatability. The problem of antimicrobial resistance is often described as a future threat in the so-called post-antibiotic era. However, our assessment concludes we may have surpassed the threshold in some of the scenarios, and that we are on the edge in others. The proposed framework, being easy to implement across sectors, while requiring little or no economic investment, unifies criteria to be used between different key actors joining two important parameters in antimicrobial resistance: the epidemiological state of priority pathogens and treatment sustainability. In the future the framework can be expanded to other pathogens and repeated assessments will be useful as an indicator of tracking trends in treatability tipping-point risks.
Mental imagery and creativity
Authors: jankowska dorota , Karwowski Maciej
Published: September 2020

Although mental imagery is crucial for creativity in many domains, its links with creative abilities are ambiguous. This paper, based on five studies (total N > 3,600), reports the development of the Polish version of the VVIQ-2 (VVIQ-PL), examines its validity and reliability, as well as tests the relationships between mental imagery and creativity. Based on the results of the confirmatory factor analyses, we demonstrated the single-dimensional structure of VIVIQ-PL and measurement invariance concerning participants’ gender. The VVIQ-PL showed excellent test-retest reliability, high internal consistency reliability, and adequate construct validity. As expected, art students were characterized by a higher level of mental imagery than ‘non-artist’ groups. Finally, however, although the vividness of visual imagery turned out to be positively correlated with creativity (creative abilities, creative imagery, and creative self-concept), the strength of these correlations was weak-to-moderate. We discuss these findings alongside future research directions.
When Getting More Makes Groups Seem Worth Less: Negotiating a ‘Better’ Deal in Prisoner Swaps Can Ironically Signal Low Self-Regard and Engender Disrespect
Authors: Dittmann Andrea G. , Kteily Nour , Bruneau Emile
Published: September 2020

Prisoner exchanges between groups in conflict are often a first step towards peace. As with bargaining more generally, groups presumably try to get the best deal possible. But when exchanging human lives, can getting ‘more’ make your group seem worth less? Building on research on signals of self-regard at the interpersonal level, we consider whether certain behaviors—even strategically beneficial ones—can diminish perceptions of the esteem in which a group holds itself, with consequences for the respect and treatment it is afforded. Across six preregistered experiments (total N = 5,060), we find that groups that negotiate a ‘better deal’ (e.g., getting multiple prisoners back in return for releasing only one outgroup prisoner; negotiating down the ‘price’ for retrieving a single prisoner) are ironically seen as placing less value on themselves, and, as a consequence, are respected less and prescribed worse treatment. We observe these results in real-world and in artificial contexts, and whether perceivers belong to the outgroup in conflict or are neutral third-party observers. A seventh study, focused on the decision to pursue or eschew a risky rescue mission (with negative expected value of lives saved) expands beyond the prisoner swap context, highlighting that our results are one manifestation of a general tendency for perceivers to intuit a group’s self-regard from its actions. Our work suggests that, when deciding between various courses of action, it would behoove groups to consider the ways in which their actions subtly communicate how highly they value themselves.
Shifting Minds: A Quantitative Reappraisal of Cognitive Intervention Research
Authors: Moreau David
Published: September 2020

Recent popular areas of research in psychology suggest that behavioral interventions can have profound effects on our cognitive abilities. In particular, the study of brain training, video gaming, mind-set and stereotype threat all include claims that low-cost, non-invasive manipulations of the environment can greatly affect individual performance. Here, I provide a quantitative reappraisal of this literature, focusing on recent meta-analytic findings. Specifically, I show that effect size distributions in the four aforementioned areas are best modeled by multiple, rather than single, latent distributions, suggesting important discrepancies in the effect sizes reported. I further demonstrate that these multimodal characteristics are not typical within the broader field of psychology, using 107 control meta-analyses published in three top-tier journals as comparison. The effect size distributions observed in cognitive intervention research therefore appear to be uncommon, with their characteristics being largely unexplained by current theoretical frameworks of cognitive improvement. Before the source of these discrepancies is better understood, the present study calls for constructive skepticism in evaluating claims of cognitive improvement following behavioral interventions, and for caution when this line of research influences large-scale policies.

Authors: McVay Megan , Cooper Kellie , Seoane Montserrat Carrera , Donahue Marissa , Scherer Laura Danielle
Published: September 2020

Objectives: Concerns about rigor and replicability have led to reforms to increase science transparency. We aimed to document the use of transparent reporting practices in behavioral medicine journals in 2018 in order to inform future efforts to improve reporting practices. We also aimed to compare 2018 reporting practices to 2008. Methods: We examined a randomly selected portion of articles published in 2018 and 2008 by the four behavioral medicine journals with the highest impact factor. We excluded manuscripts that were reviews, presented qualitative data, or were purely descriptive. We coded whether articles were clear in their presentation of analyses as being primary or secondary; whether studies were registered/pre-registered; whether they used “exploratory” or a related term to describe analyses/aims; and whether they reported power analyses. Results: We identified and coded 162 manuscripts published in 2018 (87% observational and 12% experimental). Among 2018 studies, 16% were explicit in describing outcomes as primary or secondary, 51% appeared to be reports of secondary outcomes but did not use the term “secondary,” and 33% were unclear. Registration/pre-registration occurred in 14% of studies; 77.3% of registered/pre-registered studies did not report registration timing in relation to data collection, and 91% did not report which analyses were pre-registered. “Exploratory” or a related term was used to describe an aim or analysis in 31% of studies. Power analyses were reported in 8% of studies. Compared to studies from 2008 (n=120), studies published in 2008 were less likely to clearly report whether outcomes presented were primary or secondary and less likely to have been registered/pre-registered. Conclusions: Behavioral medicine stakeholders should consider strategies to increase clarity of reporting of key analysis details.

Dendrobium sp is a type of orchid that is currently very popularly traded because it has a variety of flower types, but the growth rate is slow. Vitamin B1 (Thiamin) is a micro nutrient that is able to accelerate the division of new cells in the tissue so that it can accelerate the growth of plant vegetative organs. Atonic is a chemical that can stimulate the biochemical and physiological processes of plants, so that atonics is a growth regulator. Atonic is usually used to stimulate the growth of plant roots against nutrients, increase leaf absorption, flower discharge, fruit formation, and increase the number and weight of fruit. The purpose of this study is the Stimulation of Growth and Development of Planlet Orchid (Dendrobium sp) in the Acclimatization Stage by Provision of Vitamin B1 and Atonik.This research was conducted experimentally using a completely randomized design (CRD) with 2 factors, namely the concentration of Vitamin B1 (Thiamin) consisting of 4 treatment groups and Atonic consisting of 4 treatments. Vitamin B1 (0 ml / l, 1.5 ml / l, 3 ml / l, 4.5 ml / l) and Atonik (0 ml / l, 1 ml / l, 2 ml / l, 3 ml / l) and each treatment was repeated 2 times so that 128 plants could each treatment consisting of 4 plants with 4 sample plants. Spraying is done once a week. The parameters observed were percentage growth, plant height, stem diameter, number of leaves, primary root length and number of roots and measured at 2MST.Based on the results of research on Dendrobium sp. Can be concluded 1) Provision of Vitamin B1 significantly affect the growth of orchid plant height (Dendrobium sp). 2) The giving of Atonik significantly influences the growth of the number of leaves, root length and number of roots of orchid plants (Dendrobium sp). 3) Provision of Vitamin B1 and Atonik simultaneously can accelerate to overcome plant height, number of leaves and the budding of orchid plant roots (Dendrobium sp).
