Research on coal mining subsidence under highway can be divided into two fields: research on the problems caused by coal mining under highway and research on the problems caused by highway construction above mined-out area of coal mine.The issues about safety,design and engineering are the key points restricting the safety and the construction of highway in coal mining areas. The paper completely summarized and analysed the present situation of research on coal mining subsidence under highway and the special characteristics comparing with the general building and the railway. In order to ensure the safety of existing highways and highways in planning in coal mining areas, according to the deficiency of current research, this paper put forward the future research directions of coal mining subsidence under highway.

The prehistory of Oceania begins with the occupation of New Guinea over 50,000 years ago, up to the settlement of Aotearoa/New Zealand in the last 700 years. The Oxford Handbook of Prehistoric Oceania presents this history in regional overviews and debates through 21 chapters by leading archaeologists and scholars of allied fields. Chapters present the latest findings and future research directions on the New Guinea region and archipelagos from Vanuatu, New Caledonia, Fiji, Tonga, and Samoa in the western Pacific. Micronesia, East Polynesia, Hawaii, Aotearoa/New Zealand, and Easter Island are also discussed in individual chapters. Chapters on wider disciplinary issues summarize key points of method and theory in Oceanic archaeology, including the generation of explanations, building chronologies, linguistic prehistory, coastline evolution, settlement systems, and maritime migration.

Individual Psychological Assessment is widely practiced among I–O psychologists and supported as a core competency by a majority of the commentaries. Our response addresses some of the key points made in the commentaries, such as issues related to the definition, contextual and criterion variables, interpretation and integration methods, validity evidence, professional matters, and future research directions. We also respond to a few critics who want to entirely eliminate expert assessor judgment in IPAs. Models are presented for using assessor judgment and mechanical methods in IPAs and for distinguishing naïve and sophisticated IPA researchers and practitioners. We conclude that IPA is now widely accepted as a core part of I–O psychology.

As intrapartum fevers are not always infectious in origin, determining whether antibiotics are indicated is challenging. We previously sought to create a point-of-care calculator using clinical data available at the time of an intrapartum fever to identify the subset of women who require antibiotic treatment to avoid maternal and neonatal morbidity. Despite the use of a comprehensive dataset from our institutions, we were unable to propose a valid and highly predictive model. In this commentary, we discuss why our model failed, as well as future research directions to identify and treat true intraamniotic infection. Developing a risk-stratification model is paramount to minimizing maternal and neonatal exposure to unnecessary antibiotics while allowing for early identification of women and babies at risk for infectious morbidity.
