<p>Freezing-thaw weathering is recognized as one of the most significant factors in the fatigue of rock mass in areas where the temperature periodically fluctuates around the freezing point. <br>A one-year monthly SfM monitoring program from December 19, 2019, to January 7, 2021, was done to detect rockfall activity on a rockslide cliff composed of marl-sandstone at La Cornalle, Switzerland. More than one hundred rockfall events were detected during this period with the volumes varied from 0.005m<sup>3</sup> to 4.85m<sup>3</sup>. <br>We texture all the rockfalls on the 3D SfM model. It is shown that most of them are mainly located in three areas:  the top of the cliff, the foot of the cliff, and the medium-left part of the cliff. The common feature of these three parts is that the layers are more or less overhanging with dense fractures around them. At the same time, the meteorological data collected by a weather station on site is correlated with the rockfall events to figure out the relationship between each other. Actually, about 30% of total rockfall volume fell during winter on this site. The triggering factor of rockfall during winter is related to freezing-thaw cycling. This kind of weathering can be understood as an interplay between rock properties and its dynamic environment.<br>In order to make clear the role of freezing-thaw played on the rockfall generation, an on-site 24h monitoring measurement program that consists of two crack meters, one rock thermal sensor, and thermal camera monitoring is installed in January 2021. Those datasets will help to understand how the crack grows with the changing temperature. In addition, freezing-thaw cycling laboratory experiments for the rock samples taken from different areas of the cliff will be done with an environmental test chamber. The topography of the rock samples before and after the experiments will be acquired by a 3D handheld scanner. This work will benefit to reveal the rock surface evolution during the freezing-thaw cycling in a dynamic environment with varied humidity and number of cycles. <br>In conclusion, the combination of on-site measurements and laboratory freezing-thaw experiments will provide a good basis for a better understanding of the rockfall triggering mechanism led by physical weathering.</p>

ABSTRACT The tax return is often a key piece of evidence in a forensic accounting engagement. Forensic accounting students need to understand what a tax return can tell its reader about the taxpayer. This case is designed for an introductory or advanced course in fraud examination or forensic accounting. Students are placed in the hypothetical role of a person beginning a job as a bankruptcy auditor with the United States Trustee Program. The bankruptcy auditor must utilize two consecutive years of tax returns to determine the primary sources of income and assets for the debtor. Information from the tax returns will be compared to the bankruptcy petition to identify red flags that could indicate the debtor has committed fraud or abuse of the bankruptcy process. Successful completion of this case requires students to integrate skills from auditing, taxation, business law, and forensic accounting and communicate findings in a written report.

Targeting public procurement policies has become an important goal for European policy makers since it is believed to contribute to more sustainable food systems and food consumption patterns. Food purchased by the public for institutions such as hospitals, care homes, universities, prisons, schools, armed forces and canteens represent a significant part of the food economy in European countries. As a result governments at different levels have adopted policies that promote organic food and farming in many countries. Since agencies and institutions of the public can be expected to be influential by setting good examples of food consumption, the food for the public plate has come to take a much more visible role in public service provision policymaking over the past decades. However, for such strategies to be effective the right policy mix is essential. This paper reports on the Danish case of Public Organic Procurement Policy (POPP’s) and its role in organic food and farming strategies. It gives a brief account on component of the policy mix including the setting up of a labelling system, a monitoring system for sales volumes and a foodservice workers training program. The paper examines the first results from the monitoring system and provides insight in the progress of POPP’s. It details the implementation and maintenance of the monitoring program and discusses the role of metrics in relation to other policy tools as well as the contribution that monitoring can make in terms of policy implementation.

This study investigates the experiences of victims of domestic violence (DV) involved in a bilateral electronic monitoring (EM) program. Semi-structured interviews were conducted with six victims whose associated person of interest participated in an EM program post-release, as well as 13 victim support staff. Thematic analysis revealed seven themes: (1) Safety and validation, (2) Initial anxiety, (3) Minimal intrusion on daily life, (4) Psychological relief and feelings of safety, (5) Freedom to engage in daily activities, (6) Post-EM concerns for safety, and (7) An effective deterrent for some, but not for all. Overall, the experiences reported by victims and support staff were positive and evident of victim-centricity. The main defining experience of the DVEM program for victims was improved feelings of safety during the program and increased autonomy and confidence in going about their daily activities. However, there is an urgent need to consider post-EM safety of victims.

A variety of changes have occurred recently in perinatal care that influence the role of the pediatrician. These include new prenatal assessment techniques (ultrasonography and fetal electronic monitoring), an increased attention to the ambiance of delivery with family participation, and more rapid hospital discharge. This review will focus on the role of the general pediatrician in the care of the normal newborn in this new setting. Prenatal Pediatric Visit The pediatrician's role in the care of the normal newborn should begin with the prenatal pediatric visit during the third trimester of the pregnancy. This visit usually occurs in the pediatric office; some practitioners can schedule time for a home visit. This first meeting between parents and pediatrician frequently serves as the foundation for two decades of mutual trust, confidence, and communication. The topics that should be discussed and recorded at this visit are listed in Table 1. Serious potential problems identified during this visit may require discussion with obstetrical and neonatal colleagues. The prenatal visit should include discussions about maternal nutrition; the hazards of alcohol, cigarette smoking, and other drugs to the unborn baby; and the dangers of passive smoking once the infant is home. The pediatrician should inquire about maternal illnesses and medications.

The Ore Treatment Unit is a deactivated uranium mine and milling situated in Caldas, MG, BR. Although disabled, there are still areas considered controlled and supervised from the radiological point of view. In these areas, it is necessary to keep an occupational monitoring program to ensure the workers' safety and to prevent the dispersion of radioactive material. For area monitoring, the dose rate, in µSv∙h-1, was measured with Geiger Müller (GM) area monitors or personal electronic monitors type GM and thermoluminescence dosimetry (TLD), in mSv∙month-1, along the years 2013 to 2016. For area monitoring, 577 samples were recorded; for personal dosimeters monitoring, 2,656; and for TLD monitoring type, 5,657. The area monitoring showed a mean dose rate of 6.42 µSv∙h-1 associated to a standard deviation of 48 µSv∙h-1 with a maximum recorded value of 685 µSv∙h-1. 96 % of the samples were below the derived limit per hour for workers (10 µSv∙h-1). For the personal electronic monitoring, the average of the data sampled was 15.86 µSv∙h-1, associated to a standard deviation of 61.74 µSv∙h-1. 80 % of the samples were below the derived limit and the maximum recorded was 1,220 µSv∙h-1. Finally, the TLD showed a mean of 0.01 mSv∙h-1 (TLD detection limit is 0.2 mSv∙month-1 equivalent to 0.28 µSv∙h-1), associated to a standard deviation of 0.08 mSv∙h-1. 98% of the registered values were below 0.2 mSv∙month-1 and less than 2 % of the measurements had values above the limit of detection. The samples show areas with low risk of external exposure, as can be seen by the TLD evaluation. Specific areas with greater risk of contamination have already been identified, as well as operations at higher risks. In these cases, the use of the individual electronic dosimeter is justified for a more effective monitoring. Radioprotection identified all risks and was able to extend individual electronic monitoring to all risk operations, even with the use of the TLD.

Snowshoe hares (Lepus americanus Erxleben, 1777) fluctuate in 9–10 year cycles throughout much of their North American range. These cycles show large variations in cyclic amplitude and we ask what factors could cause amplitude variation. We gathered data from 1976 to 2012 on hare numbers in the boreal forest of Alaska, Yukon, Northwest Territories, and northern British Columbia to describe the amplitude of hare fluctuations and to evaluate four possible causes. First, weather could cause variation in amplitude via hare reproduction or survival, but this mechanism does not fit our data. Second, bottom-up processes involving forest succession could explain amplitude variation through changes in winter forage availability, but succession is too slow a variable in our study areas. Third, plant defenses entrained by hare over-browsing in one cycle can produce variation in plant quality and quantity in subsequent cycles. A mathematical model suggests this is a possible explanation. Fourth, predator recovery following the cyclic low is inversely related to hare cyclic amplitude, and the existing data are consistent with this mechanism. A standardized regional monitoring program is needed to improve our understanding of cyclic amplitude variation in hares and the possible role of predators and winter foods in affecting amplitude.
