A Commentary on the Social Perspective on Creativity
Authors: Runco Mark A. 
Published: February 2017

Abstract
This commentary examines the social perspective on creativity, as presented in the featured article. There are several attractive aspects to the social perspective, but serious limitations as well, which are detailed in this commentary. The assumptions of the social perspective are also discussed. The most questionable of these assumes that social recognition and impact are inherent parts of creativity. The parsimonious alternative is to define creativity such that it includes only what is related to creativity per se and to recognize that social recognition may follow creation and is certainly extricable from it. A defence of this parsimonious view is presented. A brief discussion of possible crises in the field of creativity studies is also presented, with one suggestion being that the diverse approaches used in the field represent a kind of divergent thinking and as such represent progress, even though it is not linear. This commentary concludes with a discussion about creativity being vital for quality of life. That perspective differs dramatically from the product view of creativity which is often tied to a social perspective.

Abstract
Creative things are always original, but they must be more than just original. They must also have some utility, effectiveness, or value. The present research tested the psychoeconomic definition of “value” and examined how value ratings fluctuated when individuals worked in groups or alone. This psychoeconomic definition of value is very different from that found in previous studies. It was based on ratings obtained after the students participating had been told that their grades depended on their teamwork. Previous studies have used hypothetical ratings of value, but here the ratings were meaningful: there was a contingency placed on making a good decision, and that decision focused on creative teamwork. This investigation also tested the idea that originality and value are both required for creativity. Psychoeconomic theory not only offers an objective and behavioural index of value. It also offers predictions about the “social costs” of working in groups. To test these ideas individuals received two tests of divergent thinking, either while alone (no social cost), working in a small group (low cost), or working in a larger group (high cost). Social preferences were controlled, as was extraversion. Results indicate that fluency did not diminish when the social costs were present. Moreover, originality increased when participants worked in groups. Findings also demonstrated that value judgments can be reliably assessed and that the interaction of value and originality accounted for a significant amount of the variability in creativity ratings.

AbstractIn active sensing, animals make motor adjustments to match sensory inputs to specialized neural circuitry. Here, we describe an active sensing system for sound level processing. The pallid bat uses downward frequency-modulated (FM) sweeps as echolocation calls for general orientation and obstacle avoidance. The bat’s auditory cortex contains a region selective for these FM sweeps (FM sweep-selective region, FMSR). We show that the vast majority of FMSR neurons are sensitive and strongly selective for relatively low levels (30-60 dB SPL). Behavioral testing shows that when a flying bat approaches a target, it reduces output call levels to keep echo levels between ∼30 and 55 dB SPL. Thus, the pallid bat behaviorally matches echo levels to an optimized neural representation of sound levels. FMSR neurons are more selective for sound levels of FM sweeps than tones, suggesting that across-frequency integration enhances level tuning. Level-dependent timing of high-frequency sideband inhibition in the receptive field shapes increased level selectivity for FM sweeps. Together with previous studies, these data indicate that the same receptive field properties shape multiple filters (sweep direction, rate, and level) for FM sweeps, a sound common in multiple vocalizations, including human speech. The matched behavioral and neural adaptations for low-intensity echolocation in the pallid bat will facilitate foraging with reduced probability of acoustic detection by prey.
Synchronous Infra-Slow Bursting in the Mouse Accessory Olfactory Bulb Emerge from Interplay between Intrinsic Neuronal Dynamics and Network Connectivity

Published: February 2017

Rhythmic neuronal activity of multiple frequency bands has been described in many brain areas and attributed to numerous brain functions. Among these, little is known about the mechanism and role of infra-slow oscillations, which have been demonstrated recently in the mouse accessory olfactory bulb (AOB). Along with prolonged responses to stimuli and distinct network connectivity, they inexplicably affect the AOB processing of social relevant stimuli. Here, we show that assemblies of AOB mitral cells are synchronized by lateral interactions through chemical and electrical synapses. Using a network model, we demonstrate that the synchronous oscillations in these assemblies emerge from interplay between intrinsic membrane properties and network connectivity. As a consequence, the AOB network topology, in which each mitral cell receives input from multiple glomeruli, enables integration of chemosensory stimuli over extended time scales by interglomerular synchrony of infra-slow bursting. These results provide a possible functional significance for the distinct AOB physiology and topology. Beyond the AOB, this study presents a general model for synchronous infra-slow bursting in neuronal networks.SIGNIFICANCE STATEMENTInfra-slow rhythmic neuronal activity with a very long (>10 s) duration has been described in many brain areas, but little is known about the role of this activity and the mechanisms that produce it. Here, we combine experimental and computational methods to show that synchronous infra-slow bursting activity in mitral cells of the mouse accessory olfactory bulb (AOB) emerges from interplay between intracellular dynamics and network connectivity. In this novel mechanism, slow intracellular Na+dynamics endow AOB mitral cells with a weak tendency to burst, which is further enhanced and stabilized by chemical and electrical synapses between them. Combined with the unique topology of the AOB network, infra-slow bursting enables integration and binding of multiple chemosensory stimuli over a prolonged time scale.

Metodología: este artículo presenta el desarrollo de dos lenguajes de dominio específico (dsl) basados en mde, uno gráfico: cnpGraph, y uno textual: cnpText, como propuesta de solución al problema. Cada herramienta genera un documento con las configuraciones de los protocolos de red requeridas para los dispositivos de red, ya sean routers o switches. Resultados: las pruebas se hicieron sobre diferentes escenarios y configuraciones, comparando los tiempos de búsqueda mediante el uso de lenguajes de dominio específico y búsquedas convencionales. Los resultados mostraron que cnpGraph y cnpText reducen en más de un 80 % el tiempo necesario para encontrar las configuraciones. Conclusiones: la característica principal, tanto de cnpGraph como de cnpText, es la posibilidad de ampliación del número de protocolos y marcas de fabricantes de routers y switchess, así como la vinculación de protocolos, con el propósito de añadir nuevos dispositivos de red de diferentes fabricantes y disponer de toda la configuración necesaria para establecer cualquier tipo de red.
Response of Spring Wheat to Sulfate‐Based Salinity Stress under Greenhouse and Field Conditions
Authors: Thapa Resham , Wick Abbey , Chatterjee Amitava 
Published: February 2017

Core Ideas
Spring wheat response to sulfate‐based salinity stress was evaluated under greenhouse and field conditions.
Soil salinity was highly variable, both horizontally and vertically, in fields.
Soil ECe affected crop growth and relative yield only under greenhouse conditions.
Under field conditions, low soil ECe in the root zone resulted in greater salinity tolerance.
Spring wheat (Triticum aestivum L.), a moderately salt‐tolerant crop, is often grown in saline areas worldwide. This study was conducted to assess spring wheat response to sulfate‐based salts under greenhouse and field conditions. In a greenhouse experiment, salinity treatments (control and 3.0, 5.0, 9.0, and 15.0 dS m−1) were established by adding Na2SO4 and MgSO4⋅7H2O salts in soil–silica mixes. Similarly, field studies were conducted in naturally saline farmers’ fields in eastern North Dakota for a total of four site‐years. In the fields, the soil was sampled to the 120‐cm depth, and the depth‐weighted mean root‐zone salinity was calculated. Results indicated a variable response of spring wheat to salinity under greenhouse and field conditions. Under greenhouse conditions, plant height and number of tillers per plant decreased significantly at a soil saturated paste extract electrical conductivity (ECe) of 5 dS m−1 and above. Similarly, root growth decreased significantly at a ECe of 9.0 dS m−1 and above. Relative kernel and straw yields were unaffected by sulfate salts up to 8.2 and 2.9 dS m−1, respectively. Above the threshold value, the kernel and straw yields declined by 12.0 and 4.9% per unit increase in ECe, respectively. In naturally saline fields, soil salinity decreased with soil depth, and the spring wheat responded by decreasing plant height by 1.2 cm per unit increase in ECe. However, root growth and relative crop yields were maintained. Our results suggest that the majority of the crop roots were exposed to low salinity levels in the surface soil layers in naturally saline fields, providing greater salinity tolerance in the crops.
