Coordinate based meta-analysis of functional neuroimaging data using activation likelihood estimation; full width half max and group comparisons. [PDF]

open access: yesPLoS ONE, 2014
Coordinate based meta-analysis (CBMA) is used to find regions of consistent activation across fMRI and PET studies selected for their functional relevance to a hypothesis.

Features extracted using tensor decomposition reflect the biological features of the temporal patterns of human blood multimodal metabolome.

open access: yesPLoS ONE, 2023
High-throughput omics technologies have enabled the profiling of entire biological systems. For the biological interpretation of such omics data, two analyses, hypothesis- and data-driven analyses including tensor decomposition, have been used.

Knowledge-Aware Debiased Inference Model Integrating Intervention and Counter-factual [PDF]

open access: yesJisuanji kexue yu tansuo
The abductive natural language inference task (Abductive NLI) seeks to select more plausible hypothetical events based on given antecedent events and consequent events. However, inherent biases such as “logical defects” and “single-sentence label leakage”

Triumphs and limits of the Contrastivity-Only Hypothesis [PDF]

open access: yesLinguistic Variation, 2015
The Variable Hierarchy hypothesis of Dresher (2009) has a number of far-reaching consequences and applications – beyond the domain for which it was originally developed – including overspecification, kinship terminology, vowel reduction and whistled languages.

What Drives Negative Investment-Cash Flow Sensitivities? Revenue Effect Versus Corporate Life-Cycle Dynamics

open access: yesSchmalenbach Journal of Business Research, 2023
In order to identify the economic driver of negative investment-cash flow sensitivities (ICFS), we derive testable predictions from extending a theoretical investment model with endogenous financing costs (“revenue effect”) and contrast them with the ...

A Comparison of Two Theories of Perceived Distance on the Ground Plane: The Angular Expansion Hypothesis and the Intrinsic Bias Hypothesis

open access: yesi-Perception, 2012
Two theories of distance perception—ie, the angular expansion hypothesis (Durgin and Li, 2011 Attention, Perception, & Psychophysics 73 1856–1870) and the intrinsic bias hypothesis (Ooi et al, 2006 Perception 35 605–624)—are compared.

A test of the “;ceiling effect”; hypothesis of positive contrast [PDF]

open access: yesPsychonomic Science, 1970
Seventy-two rats were given 0, 5, 10, or 15 small rewarded trials prior to being shifted to large reward for the remainder of 45 trials. Each of the groups which experienced an upward shift in reward magnitude rapidly approximated the performance of a consistently large rewarded control group, and in no case was a positive contrast effect observed. The

Perceptual distinctiveness between dental and palatal sibilants in different vowel contexts and its implications for phonological contrasts

open access: yesLaboratory Phonology, 2017
Mandarin Chinese has dental, palatal, and retroflex sibilants, but their contrasts before [_i] are avoided: The palatals appear before [i] while the dentals and retroflexes appear before homorganic syllabic approximants (a.k.a. apical vowels).

Geographic variation in chin shape challenges the universal facial attractiveness hypothesis. [PDF]

open access: yesPLoS ONE, 2013
The universal facial attractiveness (UFA) hypothesis proposes that some facial features are universally preferred because they are reliable signals of mate quality.
