We study multi-period college admission problems where, at each period, a matching is computed and students have the option to either finalize their matches or participate in next period. Students participating an additional run of mechanism can submit new rank order list clearinghouse. Such gradual systems adequately account for source heterogeneity among participants, like withdrawals. identi...

Abstract Gradually typed languages are designed to support both dynamically and statically programming styles while preserving the benefits of each. Sound gradually check types at runtime boundary between modules. However, there is much disagreement in gradual typing literature over how enforce complex such as tuples, lists, functions objects. In this paper, we propose a new perspective on desi...

Does Mental Productivity Decline with Age? Evidence from Chess Players We use data on international chess tournaments to study the relationship between age and mental productivity in a brain-intensive profession. We show that less talented players tend to leave the game in the earliest phases of their career. When the effects of age on productivity vary with unobserved ability, commonly used fi...

The 2014 Indian general election marked a single party – the Bharatiya Janata Party, winning a majority of seats in Lok Sabha, the first time since the 1984 election. The Congress, the other main national party, suffered its worst ever defeat. This election was termed by some as a 'critical election' signalling the advent of a new phase of a ‘BJP dominated’ party system in India. In this paper,...

OBJECTIVES Type B Niemann-Pick disease (NPD-B) caused by acid sphingomyelinase deficiency is a rare, autosomal recessive, lysosomal storage disorder with a broad range of disease severity. The objectives of this study were to document the natural history of the disease in a large, clinically heterogeneous patient population that was followed for a period of 10 years and to determine how genotyp...

Typestate reflects how the legal operations on imperative objects can change at runtime as their internal state changes. A typestate checker can statically ensure, for instance, that an object method is only called when the object is in a state for which the operation is welldefined. Prior work has shown how modular typestate checking can be achieved thanks to access permissions and state guara...

Over the past 20 years, programmers have embraced dynamically-typed programming languages. By now, they have also come to realize that programs in these languages lack reliable type information for software engineering purposes. Gradual typing addresses this problem; it empowers programmers to annotate an existing system with sound type information on a piecemeal basis. This paper presents an i...

STUDY DESIGN Retrospective cohort study. PURPOSE To examine the clinical profile and surgical complications in patients with spinal hemangioblastomas and to evaluate the long-term outcome in them. OVERVIEW OF LITERATURE Although considered to be histologically benign, hemangioblastomas may cause significant neurological deficits. The proportion of spinal hemangioblastomas associated with vo...

Handling Editor: Stephanie Castro In this study, we develop and examine a model of leaders' impression management during organizational decline by elaborating on the roles of publicity, image concerns, and incentive compensation. We propose that the publicity of decline is an important antecedent of leaders' impression management during decline. We also examine how leaders' image concerns media...
