Abstract:
This paper studies binary hypothesis testing with a single sensor that communicates with two decision centers over a memoryless broadcast channel. The main focus lies on the tradeoff between the two type-II error exponents achievable at the two decision centers. In our proposed scheme, we can partially mitigate this tradeoff when the transmitter has a probability larger than 1/2 to distinguish the alternate hypotheses at the decision centers, i.e., the hypotheses under which the decision centers wish to maximize their error exponents. In the cases where these hypotheses cannot be distinguished at the transmitter (because both decision centers have the same alternative hypothesis or because the transmitter’s observations have the same marginal distribution under both hypotheses), our scheme shows an important tradeoff between the two exponents. The results in this paper thus reinforce the previous conclusions drawn for a setup where communication is over a common noiseless link. Compared to such a noiseless scenario, here, however, we observe that even when the transmitter can distinguish the two hypotheses, a small exponent tradeoff can persist, simply because the noise in the channel prevents the transmitter to perfectly describe its guess of the hypothesis to the two decision centers.

Abstract:
Simple hypotheses are intrinsically attractive, and, for this reason, need to be formulated with utmost precision if they are to be testable. Unfortunately, it is hard to see how Phillips & Singer's hypothesis might be unambiguously refuted. Despite this, the authors have provided much evidence consistent with the hypothesis, and have proposed a natural and powerful extension for information theoretic approaches to learning.

Abstract:
AbstractContrafreeloading (CFL) behaviour, in which animals forage persistently in patches that require effort to exploit when patches containing ad lib. food are easily available, seems to contradict the predictions of optimal foraging theory. However, it has been proposed that contrafreeloaders are in fact exploiting a hidden resource, namely information about patches that may be useful in future foraging attempts. We performed two experiments on starlings Sturnus vulgaris to test this hypothesis by determining the circumstances in which CFL occurs and assessing whether any useful information is acquired by animals performing the behaviour. In accordance with previous results we found that CFL is reduced when foragers are previously deprived of food and also when there are means of gathering information aside from sampling (namely when patches that require effort to exploit can be visually inspected). We also found that useful information is acquired by birds that perform CFL, in that when subsequently tested in extinction with the best patch removed they reliably chose the patch that had been the second best. These results are consistent with the information gain hypothesis. However, birds with low levels of CFL did not perform discernably worse in this test of patch knowledge and experimental reductions in CFL achieved through deprivation treatments did not produce apparent reductions in useful information possessed.

Abstract:
Summary: In behavioral assessment, the strategy theoretically most coherent for case formulation is to carry out a functional analysis aimed at discovering, among other factors, functionally relevant stimuli acting upon the problem-behavior. However, little is known about the decision-making processes involved in this task. Although many authors have suggested prescriptive models for this process, the strategies used by clinicians when gathering information seem to be left to experience and common sense. The present research is an attempt to increase the knowledge about this process of information gathering. The study was carried out with psychology students in their final year who already had enough theoretical knowledge to gather this kind of information, but still lacked practical experience. Subjects were asked to gather information aimed at checking a hypothesis about the functional role on a given behavior of either an antecedent or a subsequent (i.e., reinforcing) stimulus. The results show that information gathered to test a reinforcing stimulus hypothesis is more homogeneous than information to test a hypothesis about a functionally relevant antecedent stimulus. The strategies used to test both types of hypotheses are different. In both instances, however, subjects more frequently gathered information useful to refute or refine the hypothesis than information useful to verify it.

Abstract:
By appropriately partitioning the joint hypothesis of weak exogeneity and the maintained overidentifying restrictions in the linear dynamic simultaneous equations model and showing that the component subhypotheses are separable, asymptotically optimal tests for the weak exogeneity hypothesis may be constructed using limited information statistics. A necessary and sufficient condition for the separability of parametric hypotheses of the mixed implicit function and constraint equation type is derived which generalizes conditions previously obtained in the literature. Consequently, limited and full information procedures for testing the weak exogeneity hypothesis are asymptotically equivalent. The impact of these results for testing strong exogeneity in the linear dynamic simultaneous equations model is also explored.

Abstract:
This paper examines the relationships between flows and returns for five exchange traded funds (ETF) in the U.S. energy sector. Four alternative hypotheses are tested, including the price pressure hypothesis, information (or price release) hypothesis, feedback trading hypothesis, and smoothing hypothesis. The five ETF are the Energy Select Sector SPDR Fund (XLE), iShares U.S. Energy ETF (IYE), iShares Global Energy ETF (IXC), Vanguard Energy ETF (VDE), and PowerShares Dynamic Energy Exploration & Production Portfolio (PXE). A vector autoregressive (VAR) model is used to analyze the relationships between energy flows and returns. The empirical results show that energy ETF flows and subsequent returns have a negative relationship, thereby supporting the smoothing hypothesis. Moreover, the smoothing effect exists for XLE and IYE during the global financial crisis. Regardless of whether the whole sample period or the sub-samples before, during and after the global financial crisis are used, no evidence is found in support of the price pressure hypothesis, information hypothesis, or feedback trading hypothesis.

Abstract:
Objectives. Summarizing the results of research on the impact of information and communication technologies on family social capital. Background. In recent years, public and scientific discourse has constantly raised questions about how modern information and communication technologies (ICT) af¬fect interpersonal relations and family relations in particular. Studies on the impact of information and communication technologies on family social capital show conflicting results. Conclusions. Conventionally, the results of these studies can be combined around four hypotheses: 1) “Displacement hypothesis” — ICT displace direct interaction between family members and reduce the level of social capital in the family; 2) “Activation hypothesis” — ICT on the contrary contribute to the development and maintenance of relations between family members; 3) “Enrichment hypothesis” — families with inherently strong bonds and social resources benefit even more from the use of ICTs in terms of social interaction, and in families with inherently weak bonds, they will be further weakened by the use of ICTs; 4) “Social compensation hypothesis” — ICT is a kind of copping strategy that allows an individual to cope with stress due to family conflicts, low social capital, as well as to develop social interaction skills and create strong social ties for those individuals who initially did not develop these relations due to external (disability, etc.) and personal reasons (isolation, introversion, etc.). Each of the distinguished hypotheses is considered in more detail.

Abstract:
Information theory teaches that entropy is the fundamental limit for data compression, and electrical engineers routinely use entropy as a criterion for efficient storage and transmission of information. Since modern financial theory teaches that competitive market prices store and transmit information with some efficiency, should financial economists be concerned with entropy? This paper presents a market model in which entropy emerges endogenously as a condition for the operational efficiency of price discovery while entropy maximization emerges as a condition for the informational efficiency of market prices. The maximum-entropy formalism makes the efficient market hypothesis operational and testable. This formalism is used to establish that entropic markets admit no arbitrage and support both the Ross arbitrage pricing theory and the Black–Scholes stock option pricing model.

Abstract:
This paper considers the problem of learning the ranking of a set of stochastic alternatives based upon incomplete information (i.e., a limited number of samples). We describe a system that, at each decision cycle, outputs either a complete ordering on the hypotheses or decides to gather additional information (i.e., observations) at some cost. The ranking problem is a generalization of the previously studied hypothesis selection problem - in selection, an algorithm must select the single best hypothesis, while in ranking, an algorithm must order all the hypotheses. The central problem we address is achieving the desired ranking quality while minimizing the cost of acquiring additional samples. We describe two algorithms for hypothesis ranking and their application for the probably approximately correct (PAC) and expected loss (EL) learning criteria. Empirical results are provided to demonstrate the effectiveness of these ranking procedures on both synthetic and real-world datasets.

Abstract:
Purpose Various directional hypotheses for the observed links between aging, hearing, and cognition have been proposed: (a) cognitive load on perception hypothesis, (b) information degradation hypothesis, (c) sensory deprivation hypothesis, and (d) common cause hypothesis. Supporting evidence for all 4 hypotheses has been reported. No studies have modeled the corresponding 4 causal pathways into 1 single model, which would be required to evidence that multiple directional hypotheses apply. The aim of the current study was to tease out which pathways apply for 5 different cognitive measures. Method Data from 1,029 respondents of the Longitudinal Aging Study Amsterdam were used spanning a maximum follow-up of 7 years (3 measurements). Speech-in-noise recognition ability (digit triplet speech-in-noise test) was included as a measure of auditory function. Cognitive measures included global cognitive functioning, fluid intelligence, information processing speed, and verbal memory (immediate recall and retention). Bivariate dual change score modeling was used to model the causal pathways between hearing, cognition, and baseline age. Results For information processing speed, global cognitive functioning, fluid intelligence, and memory-immediate recall, all pathways except for the sensory deprivation pathway were supported. For memory-retention, only the common cause and the sensory deprivation pathways were supported. Conclusions Causal pathways corresponding to all 4 hypotheses were supported. Support for the common cause hypothesis, the information degradation hypothesis, and the cognitive load on perception hypotheses was found for 4 of 5 cognitive measures. This was unexpected in some cases (e.g., support for the information degradation pathway for cognitive measures that do not rely on auditory stimuli). The sensory deprivation pathway that emerged for memory-retention might point toward processes related to early stages of dementia. In summary, the results show that the links between decline in auditory function, cognition, and aging are complex and most likely are captured by pathways belonging to various directional hypotheses.

Abstract:
The present study investigates the applicability of an information integration hypothesis developed by Wickens and Boles (1983), to display format and response configuration. Twenty paid subjects performed either a dual-task or an integration task. The tasks were similar in all respects with the exception of information integration requirements. Proximity was manipulated via display format and response configuration. Results of the display format manipulation supported a multiple resources interpretation while the effects of response configuration were consistent with the integration hypothesis. These results point to a possible limitation in applying the integration hypothesis to resource demands of displays, but suggest that the hypothesis may apply to response configuration.

Abstract:
The hypothesis that paroxetine decreases morbidity and mortality in patients with heart failure (HF) is plausible but unproven. Basic research demonstrates that inhibition of G protein-coupled receptor kinase 2 (GRK2) both in vitro and in vivo in the myocardium may be beneficial. G protein-coupled receptor kinase 2 antagonism is purported to exert cardioprotective effects immediately following myocardial injury by blunting toxic overstimulation on a recently injured heart. In addition, chronic overexpression of GRK2 inhibits catecholamine induction of vital positive chronotropic and ionotropic effects required to preserve cardiac output leading to worsening of congestive HF. In cardiac-specific GRK2 conditional knockout mice, there is significant improvement in left ventricular wall thickness, left ventricular end-diastolic diameter (LVEDD), and ejection fraction (EF) compared to controls. Paroxetine is a selective serotonin reuptake inhibitor which was recently shown to have the ability to directly inhibit GRK2 both in vitro and in vivo. At physiologic temperatures, paroxetine inhibits GRK2-dependent phosphorylation of an activated G-protein-coupled receptor with a half maximal inhibitory concentration of 35 micromoles, a substantially greater affinity than for other G protein-coupled receptor kinases. In a randomized trial in mice with systolic HF and depressed EF postmyocardial infarction, those treated with paroxetine had a 30% increase in EF, improved contractility, and LVEDD and wall thickness compared to those treated with medical therapy alone. While further basic research may continue to elucidate plausible mechanisms of benefit and observational studies will contribute important relevant information, large scale randomized trials designed a priori to do so are necessary to test the hypothesis.
