Private Placement and Share Price Reaction: Evidence from the Australian Biotechnology and Health Care Sector

This paper analyses Private Placements for the Australian biotechnology sector. Private placement is one of the favoured methods of secondary equity offering around the world. However, it is also the least studied corporate financing mechanism. A major issue around private placement is the impact of issuance to a selected group of institutional and/or high net worth sophisticated investors and the high direct costs of doing so. We first employ en event study methodology to separate out the large and small placement effects and short and long run effects. Given Australia’s weaker regulatory environment, we find significant negative cumulative abnormal return following private placements in the short term supporting the price pressure hypothesis with our main sample and with large private placement issues. Consistent with current empirical studies, mixed evidence regarding the directional impact was also observed as small issue exhibited positive price effects. We then hypothesize a model to measure and test the key factors identified in the literature. The model captures and explains strong medium term cumulative abnormal return effects and these effects are quite different between small and large placements.private placement, event study, price effect, price pressure

Automatic Extraction of Commonsense LocatedNear Knowledge

LocatedNear relation is a kind of commonsense knowledge describing two physical objects that are typically found near each other in real life. In this paper, we study how to automatically extract such relationship through a sentence-level relation classifier and aggregating the scores of entity pairs from a large corpus. Also, we release two benchmark datasets for evaluation and future research.Comment: Accepted by ACL 2018. A preliminary version is presented on AKBC@NIPS'1

Siri, Can You Keep a Secret? A Balanced Approach to Fourth Amendment Principles and Location Data

42 pagesThe Fourth Amendment to the United States Constitution provides the right for “people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures.” Underlying this phrase are guiding principles that have deep roots reaching as far as the Roman Empire. But how do historic principles apply to modern society

Enhancing Domain Word Embedding via Latent Semantic Imputation

We present a novel method named Latent Semantic Imputation (LSI) to transfer external knowledge into semantic space for enhancing word embedding. The method integrates graph theory to extract the latent manifold structure of the entities in the affinity space and leverages non-negative least squares with standard simplex constraints and power iteration method to derive spectral embeddings. It provides an effective and efficient approach to combining entity representations defined in different Euclidean spaces. Specifically, our approach generates and imputes reliable embedding vectors for low-frequency words in the semantic space and benefits downstream language tasks that depend on word embedding. We conduct comprehensive experiments on a carefully designed classification problem and language modeling and demonstrate the superiority of the enhanced embedding via LSI over several well-known benchmark embeddings. We also confirm the consistency of the results under different parameter settings of our method.Comment: ACM SIGKDD 201

Stereotypes On Aging And Effects On The Health Of Older Adult Couples

Negative stereotypes of aging are widespread in American culture and have been shown to have detrimental effects on the health of older individuals. Little has been done to examine the dynamics of views on aging in older adult relationships. We aim to examine the stereotypes of aging held by older married couples in which one individual has a musculoskeletal condition. Specifically we\u27re interested in seeing if an individual\u27s stereotypes of aging affect (1) their own physical and psychological, and relationship health (2) their partner\u27s physical, psychological, and relationship health and (3) whether there are interaction effects of aging attitudes in relationships in predicting these health outcomes. Using self-report questionnaires, we obtained data describing participants\u27 health conditions, depressive symptoms, and martial satisfaction as well as a measure of their attitudes toward aging asking them to provide 5 words related to aging (Levy & Langer, 1994). Those words were coded on a 5 point scale of positivity. Baseline blood pressure readings were also taken of all participants in the study. We found there to be no significant correlations between attitudes of partners and no main effects of their attitudes on health outcomes. However, we found there to be significant interactions between partners\u27 views on aging in predicting care recipient physical health status and caregiver blood pressure. Agreement of attitudes in relationships is associated with more sick care recipients and lower blood pressure for caregivers. Future research should be directed at further examining the dynamics between partner attitudes as a predictor of personal and relationship health as we found preliminary evidence that such dynamics do have an impact on the health outcomes of partners in relationships
