AbstractScottish Gaelic is sometimes described as having nasalized fricatives (/ṽ/ distinctively, and [f̃, x̃, h̃], etc. through assimilation). However, there are claims that it is not aerodynamically possible to open the velum for nasalization while maintaining frication noise. We present aerodynamic data from 14 native Scottish Gaelic speakers to determine how the posited nasalized fricatives in this language are realized. Most tokens demonstrate loss of nasalization, but nasalization does occur in some contexts without aerodynamic conflict, e.g., nasalization with the consonant realized as an approximant, nasalization of [h̃], nasalization on the preceding vowel, or sequential frication and nasalization. Furthermore, a very few tokens do contain simultaneous nasalization and frication with a trade-off in airflow. We also present perceptual evidence showing that Gaelic listeners can hear this distinction slightly better than chance. Thus, instrumental data from one of the few languages in the world described as having nasalized fricatives confirms that the claimed sounds are not made by producing strong nasalization concurrently with clear frication noise. Furthermore, although speakers most often neutralize the nasalization, when they maintain it, they do so through a variety of phonetic mechanisms, even within a single language.

This article reviews recent literature on the Axial Age as a phase of world history and seeks to illuminate the role of Christian missionaries as part of this broad perspective. Introduced by Karl Jaspers in 1949, the concept has attracted attention from scholars interested in human development. The cognitive psychologist Merlin Donald views it as the third stage of “brain-culture co-evolution,” which draws on the external memory storage that literacy provides. I argue that missionaries have been central agents in conveying such stored knowledge to non-axial cultures.

Summary Policy planning has a long history in the Ministries of Foreign Affairs around the world. This article provides an overview of almost 70 years of this technique in Brazil’s Ministry of External Relations (Itamaraty). I will argue that there has been a clear trade-off between predicting, preaching, disrupting and managing. Despite its failures, planning has been an important tool for coping with uncertainty and has provided coherence in foreign policy-making.

With 225 million subscribers, India has the world’s third largest mobile subscriber base in the world. The Indian mobile industry is also one of the most competitive in the world with 4-7 operators in each service area. A large number of operators bring competition and its associated benefits such as decrease in price and hence corresponding growth of the market. On the other hand in the presence of economies of scale, too many operators may result in inefficient scales and high unit costs. This article analyses the trade-off between competition and economies of scale by estimating the production function for mobile subscribers and traffic carried. Analysis of panel data reveals the existence of economies of scale in the Indian mobile sector. We then derive an upper bound on the optimal number of operators in each license area and discuss policy implications.

This essay presents two interviews with Dario Argento, one conducted by Élie Castiel and the other by Stephane Derderian. In the Castiel interview, Argento talks about early influences on his career; his approach to every film; eroticism and sadism as well as the question of voyeurism in his work; the importance of objects in the genre films that he has made; and the future of horror films. In the Derderian interview, Argento shares his thoughts on the bloodiness in Deep Red; what the subject of visual memory that often comes up in his films such as The Bird with the Crystal Plumage represent for him; the place of homosexuality in his films; why people who see his films don't look for a suspect as much as they look for a truth; the psychology of the murderer vs. the psychology of the investigator in his films; and the presence of the world of painting in Deep Red, The Bird with the Crystal Plumage, and The Stendhal Syndrome.

Abstract This paper reviews the economic rationale for and against decentralization with particular attention to the organization and delivery of education. The paper frames the overview within the standard efficiency-equity trade off and highlights the increasingly important role of incentive mechanisms, accountability, and citizens' participation. The discussion then turns to the issues that are specific to decentralizing education, including the pros and cons of financing schools from local taxes, and a taxonomy and description of institutional arrangements around the world. A brief review of evaluation studies of decentralization reforms in education concludes the paper.

AbstractCan the output of human cognition be predicted from the assumption that it is an optimal response to the information-processing demands of the environment? A methodology called rational analysis is described for deriving predictions about cognitive phenomena using optimization assumptions. The predictions flow from the statistical structure of the environment and not the assumed structure of the mind. Bayesian inference is used, assuming that people start with a weak prior model of the world which they integrate with experience to develop stronger models of specific aspects of the world. Cognitive performance maximizes the difference between the expected gain and cost of mental effort. (1) Memory performance can be predicted on the assumption that retrieval seeks a maximal trade-off between the probability of finding the relevant memories and the effort required to do so; in (2) categorization performance there is a similar trade-off between accuracy in predicting object features and the cost of hypothesis formation; in (3) casual inference the trade-off is between accuracy in predicting future events and the cost of hypothesis formation; and in (4) problem solving it is between the probability of achieving goals and the cost of both external and mental problem-solving search. The implemention of these rational prescriptions in neurally plausible architecture is also discussed.

Aspect-based sentiment classification aims to identify sentiment polarity expressed towards a given opinion target in a sentence. The sentiment polarity of the target is not only highly determined by sentiment semantic context but also correlated with the concerned opinion target. Existing works cannot effectively capture and store the inter-dependence between the opinion target and its context. To solve this issue, we propose a novel model of Attentive Neural Turing Machines (ANTM). Via interactive read-write operations between an external memory storage and a recurrent controller, ANTM can learn the dependable correlation of the opinion target to context and concentrate on crucial sentiment information. Specifically, ANTM separates the information of storage and computation, which extends the capabilities of the controller to learn and store sequential features. The read and write operations enable ANTM to adaptively keep track of the interactive attention history between memory content and controller state. Moreover, we append target entity embeddings into both input and output of the controller in order to augment the integration of target information. We evaluate our model on SemEval2014 dataset which contains reviews of Laptop and Restaurant domains and Twitter review dataset. Experimental results verify that our model achieves state-of-the-art performance on aspect-based sentiment classification.
