Innate cognitive capacities: the poverty of the stimulus argument vs. the curry argument
The article is dedicated to the popular argument among nativists, who use it against the empiricist approach. We analyze the strongest objection against the poverty of the stimulus argument which is the curry argument. As a result of the critical consideration of the poverty of the stimulus discussion, we conclude that the curry argument is quite sound

Evaluation of the Effectiveness of Group Actions of airfighters, with Joint Guidance of Attacking Fighters and Cover Airfighters
В данной статье определен и обоснован показатель эффективности групповых
действий истребителей в виде среднего числа сохраненных истребителей в процессе группового
воздушного противоборства. На основе модели динамики средних установлена зависимость
данного тактического показателя эффективности групповых действий от технического
показателя эффективности функционирования бортовой радиолокационной системы
в условиях непреднамеренных помех в виде реализуемого коэффициента подавления бортовой
радиолокационной системы и подхода, основанного на распределении частных тактических
задач между истребителями группы. Проведены расчеты и моделирование, свидетельствующие
о повышении эффективности групповых действий истребителей при распределении задач
атакующего истребителя и истребителя прикрытия в составе группы и учете данных задач
в процессе наведенияThis article defines and justifies the efficiency indicator of group actions of airfighters in the form of the average number of saved airfighters in the process of group air confrontation. Based on the model of the dynamics of averages, the dependence of this tactical indicator of the effectiveness of group actions on the technical indicator of the effectiveness of the on-board radar system in the conditions of unintended interference in the form of the implemented suppression coefficient of the on-board radar system and the approach based on the distribution of private tactical tasks between the fighters of the group is established. Calculations and simulations have been carried out, indicating an increase in the effectiveness of group actions of fighters in the distribution of tasks of an attacking fighter and a fighter as part of a group and taking into account these tasks in the guidance proces
The Method of Targeting a Group of Fighters, Taking Into Account the Nature of the Tasks they Solve
В данной статье, в интересах повышения эффективности групповых действий
истребителей, синтезирован метод наведения группы истребителей в составе ударного истребителя,
истребителя прикрытия и истребителя информационного обеспечения на ВЦ, учитывающий
тактическое назначение каждого истребителя в составе группы, а также оценены характеристики
данного метода на основе моделирования. В рамках синтеза определен локальный квадратичный
функционал качества, позволяющий учесть точность наведения ударного истребителя,
осуществляющего наведение в зону возможного пуска ракет класса «воздух-воздух
», точность
поддержания параметров боевого порядка истребителем прикрытия относительно ударного
истребителя, точность поддержания параметров боевого порядка истребителем информационного
обеспечения относительно истребителя прикрытия и экономичность сигналов управления.
Определен перечень измерителей, которые необходимы для реализации синтезированного
метода, что свидетельствует о его практической реализуемостиIn this article, in the interests of improving the effectiveness of group actions of fighters, the method of targeting a group of fighters as part of a strike fighter, a cover fighter and an information support fighter at the VC, taking into account the tactical purpose of each fighter in the group, is synthesized, and the characteristics of this method are evaluated on the basis of modeling. Within the framework of the synthesis, a local quadratic quality functional is defined that allows taking into account the accuracy of the guidance of the strike fighter, which is aimed at the zone of possible launch of air-to-air missiles, the accuracy of maintaining the parameters of the combat order by the cover fighter relative to the strike fighter, the accuracy of maintaining the parameters of the combat order by the information support fighter relative to the cover fighter, and the cost-effectiveness of control signals. The list of meters that are necessary for the implementation of the synthesized method is determined, which indicates its practical feasibilit

A crowdsourced valuation of recreational ecosystem services using social media data: An application to a tropical wetland in India
Online social media represent an extensive, opportunistic source of behavioral data and revealed preferences for ecosystem services (ES) analysis. Such data may allow to advance the approach, scale and timespan to which ES are assessed, mapping and valued. This is especially relevant in the context of developing regions whose decision support tools are often limited by a lack of resources and funding. This research presents an economic valuation tool for recreational ES, suitable at wide spatial scales, relying on crowdsourced metadata from social media with a proof of concept tested on an Indian tropical Ramsar wetland. We demonstrate how geotagged photographs from Flickr can be used in the context of a developing country to (i) map nature-based recreation patterns, (ii) value recreational ecosystem services, and (iii) investigate how recreational benefits are affected by changes in ecosystem quality. The case-study application is the Vembanad Lake in Kerala, India, and the adjacent backwaters. Geographic Information Systems are implemented to extract 4328 Flickr photographs that are used to map hot spots of recreation and infer the home location of wetland visitors from within Kerala state with good accuracy. An individual, single-site travel cost demand function is generated and estimated using both Poisson and Negative Binomial regressions, which results in mean consumer surplus estimates between Rs. 2227–3953 (62) per visit and annual domestic recreation benefits of Rs. 7.53–13.37 billion (205 million) in the investigated wetlands. Improvement in water quality to a level that supports wildlife and fisheries is projected to result in a Rs. 260 million (760,000) in yearly value increase
