In U.S. social welfare history, many have suggested that if benefits were too attractive, consumers would come out of the woodwork to take advantage of the opportunity. Clinical trials have provided evidence of the woodwork effect's existence, suggesting caution when expanding home- and community-based services (HCBS). However, it is unclear whether these studies are best suited to assess whether a system-level effect occurs. Using state and federal data tracking Ohio's long-term services and support (LTSS) system from 1995 to 2015, this paper examines changes in the utilization rates and expenditures of Medicaid LTSS to explore whether a woodwork effect occurred as Ohio moved to improve its LTSS system balance (80% Nursing Home [NH], 20% HCBS) to (49% Nursing Home [NH], 51% HCBS)...

Microscopic study of the edges of Late to Terminal Classic Maya (AD 600-900) chert stone tools from the Paynes Creek Salt Works, Belize, indicates most tools were used for cutting fish or meat or working hide, which was unexpected, given the virtual absence of fish or other animal remains at this large salt-production complex. Use-wear study shows that a minority of stone tools have edge-wear from woodworking. Our study suggests that salting fish was a significant activity at the salt works, which corresponds to Roman, Chinese, and other East Asian civilizations, where salt and salted fish were critical components of food storage, trade, and state finance...

The second century CE Roman watermill complex of Barbegal, France, is regarded as one of the first industrial complexes in human history. The 16 water wheels are no longer extant as all woodwork has decayed. However, carbonate deposits precipitated from water during operation of the mills forming casts on the woodwork. These casts are preserved in fragments and provide unique insights into the frequency of use and maintenance of the mills, and even into the structure of the water wheel chambers. Stable isotope time series of carbonate deposits reveal that the mill activity was regularly interrupted for several months...

Objectives: There is a lack of longitudinal studies exploring the association between organic wood dust exposure and new-onset chronic obstructive pulmonary disease (COPD) and change in lung function. We have re-investigated these associations in a 6-year follow-up cohort of furniture workers exposed to wood dust using improved outcome measures and methods. Methods: A large follow-up study of 1112 woodworkers (63%) from the Danish furniture industry and 235 controls (57%) was conducted between 1998 and 2004...

Discovering materials that exhibit zero linear compressibility (ZLC) behavior under hydrostatic pressure is extremely difficult. To date, only a handful of ZLC materials have been found, and almost all of them are ultrahard materials with densified structures. Here, to explore ZLC in nondense materials, a structural model analogous to the structure of the "Lu-Ban stool," a product of traditional Chinese woodworking invented 2500 years ago, is proposed. The application of this model to borates leads to the discovery of ZLC in AEB2 O4 (AE = Ca and Sr) with the unique "Lu-Ban stool"-like structure, which can obtain a subtle mechanical balance between pressure-induced expansion and contraction effects...

Background: The Occupational Safety and Health Monitoring and Assessment Tool (OSH-MAT) is a practical instrument that is currently used in the German woodworking and metalworking industries to monitor safety conditions at workplaces. The 12-item scoring system has three subscales rating technical, organizational, and personnel-related conditions in a company. Each item has a rating value ranging from 1 to 9, with higher values indicating higher standard of safety conditions. Methods: The reliability of this instrument was evaluated in a cross-sectional survey among 128 companies and its validity among 30,514 companies...

Cellulose is the most abundant and broadly distributed organic compound and industrial by-product on Earth. However, despite decades of extensive research, the bottom-up use of cellulose to fabricate 3D objects is still plagued with problems that restrict its practical applications: derivatives with vast polluting effects, use in combination with plastics, lack of scalability and high production cost. Here we demonstrate the general use of cellulose to manufacture large 3D objects. Our approach diverges from the common association of cellulose with green plants and it is inspired by the wall of the fungus-like oomycetes, which is reproduced introducing small amounts of chitin between cellulose fibers...

The use of both naturally occurring and synthetic pigmented wood has been prevalent in woodcraft for centuries. Modern manifestations generally involve either woodworkers' aniline dyes, or pigments derived from a special class of fungi known as spalting fungi. While fungal pigments are more renewable than anilines and pose less of an environmental risk, the carrier required for these pigments-dichloromethane (DCM)-is both problematic for humans and tends to only deposit the pigments on the surface of wood instead of evenly within the material...

BACKGROUND: The purpose of this study was to assess the relevancy of flexible nasoendoscopy as a routine screening procedure of sinonasal adenocarcinoma among people occupationally exposed to wood dust. METHODS: This study included woodworkers, occupationally exposed to wood dust. Evaluations were scheduled at the time of inclusion (T0) and after a 2-year period (T1). A questionnaire was used for standardized data collection. The score was based on anatomic landmarks on each side that are parts of the olfactory clefts: the area of middle turbinate, the anterior part of the olfactory cleft, the top of the choanal arch, the spheno-ethmoidal recess, the posterior part of the olfactory cleft, and the middle part of the olfactory cleft...

In normal-hearing (NH) adults, long-term music training may benefit music and speech perception, even when listening to spectro-temporally degraded signals as experienced by cochlear implant (CI) users. In this study, we compared two different music training approaches in CI users and their effects on speech and music perception, as it remains unclear which approach to music training might be best. The approaches differed in terms of music exercises and social interaction. For the pitch/timbre group, melodic contour identification (MCI) training was performed using computer software...

Recent research has shown that concern about the apprehension and deportation of undocumented immigrants can affect how members of their households who are eligible for public benefits choose to participate in public programs. The extent to which this "chilling effect" broadly affects adults' Medicaid enrollment nationally remains unclear, in part because of the difficulty of isolating undocumented immigrants in survey data. In this study we identified households that likely included undocumented immigrants and then examined whether gains in health care coverage due to the expansion of Medicaid eligibility under the Affordable Care Act (ACA) were dampened for eligible people living in households with mixed immigration status...

The enantioselective synthesis of fully benzenoid single and double carbo[6]helicenes has been achieved via the gold-catalyzed intramolecular hydroarylation. The single crystal of the racemic double carbo[6]helicene consists of unique layer structures like timbers with halving joints in the woodworking. Furthermore, the double carbo[6]helicenes exhibited relatively large CPL activities among chiral small organic molecules.

The current study analyzed 312 caught-in-between fatalities caused by machinery and vehicles. A comprehensive and mutually exclusive coding scheme was developed to analyze and code each caught-in-between fatality in terms of age, gender, experience of the victim, type of industry, source of injury, and causes for these accidents. Boolean algebra analysis was applied on these 312 caught-in-between fatalities to derive minimal cut set (MCS) causes associated with each source of injury. Eventually, contributing factors and common accident patterns associated with (1) special process machinery including textile, printing, packaging machinery, (2) metal, woodworking, and special material machinery, (3) conveyor, (4) vehicle, (5) crane, (6) construction machinery, and (7) elevator can be divided into three major groups through Boolean algebra and MCS analysis...

In Uruguay wood-impregnation plants use chromated copper arsenate (CCA) as preservative applying good manufacture practices (GMP). This study aims a retrospective evaluation of toxicologically relevant species levels in CCA exposed woodworker's urine (As-U) and an assessment of the effects of work risk factors and non-occupational sources in As-U of workers from a selected plant. From 2014 to 2016, As-U in 212 urine samples (As-U) of 73 woodworkers from six CCA impregnation plants were determined. In one of these plants, 35 workers were interviewed to obtain individual data of work tasks, lifestyles, diet, habits, etc...

A 74-year-old Caucasian man with poorly controlled diabetes and hypertension was seen in the dermatology clinic for treatment of a nodular basal cell carcinoma on his right temple. He had poorly controlled diabetes for decades and had been insulin dependent for 20 to 25 years. He had not been on any anticoagulation therapy in the past or present and had no history of a hematologic disorder. He was retired and did woodworking as a hobby. During a routine presurgical head and neck skin examination, he was noted to have macular bluegray dyspigmentation of the central portion of the anterior portion of his ear lobes, bilaterally (Figure 1)...
