Is the work-from-home concept here to stay? Study of changes in rental income from commercial real estate firms.

In March of 2020, the COVID-19 pandemic caused a sudden influx of employees working from home full-time. A study of 100,000 tweets in spring 2020 showed a 73% positive sentiment toward working from home (Dubey & Tripathi, 2020). In October 2020, Rutgers reported between 14 and 203 million Americans plan to relocate in response to the availability of work-from-home assignments. That might signal a shift in demand for companies connected to residential real estate; however, one industry is positioned to lose big if Americans don't return to office buildings: commercial real estate. We analyzed the 2019 and 2020 quarterly financial statements of seven commercial real estate firms that specialize in renting office space and found evidence of changes in revenue and net property, plant, & equipment. Q2 2020 quickly showed an average decrease in rental income by more than 12% from Q1. The decrease suggests that while many companies are closing brick-and-mortar locations and workers anticipate a permanent work-from-home status, their landlords are not yet experiencing a significant change in their rental income or PPE. The average long-term lease for office space is around 3-5 years (Smith, 2021), so it may take years to see an impact as clients decide now to renew leases in the future and management completes existing projects

Evaluating A State Opioid Prescribing Limit and Electronic Medical Record Alert

Because long-term opioid use has been linked to the length and strength of an initial prescription, 33 states, Medicare, and some private insurers have set limits on the duration of new opioid prescriptions. In May 2017, New Jersey implemented a statewide 5-day limit on new opioid prescriptions and Penn Medicine implemented an Electronic Medical Record (EMR) alert to notify prescribers when a prescription exceeded the limit and provide compliant prescription orders. This study compared outcomes in Penn Medicine outpatient practices in New Jersey with its practices in Pennsylvania not subject to the law. Outcomes included total opioid dose and number of tablets per prescription as well as rates of prescription refills, health care visits, and telephone calls within 30 days to account for potential unintended consequences

Highly Regioselective Nitrile Oxide Dipolar Cycloadditions with ortho-Nitrophenyl Alkynes

The dipolar cylcoadditions of ortho-nitrophenyl alkynes with aryl nitrile oxides has been demonstrated. A range of substituents are tolerated on the alkyne. These reactions proceed with excellent levels of regioselectivity. Subsequent functionalization of the isoxazole scaffold has been demonstrated.This is the author's peer-reviewed final manuscript, as accepted by the publisher.

Definitions and methods of measuring and reporting on injurious falls in randomised controlled fall prevention trials: a systematic review

<p>Abstract</p> <p>Background</p> <p>The standardisation of the assessment methodology and case definition represents a major precondition for the comparison of study results and the conduction of meta-analyses. International guidelines provide recommendations for the standardisation of falls methodology; however, injurious falls have not been targeted. The aim of the present article was to review systematically the range of case definitions and methods used to measure and report on injurious falls in randomised controlled trials (RCTs) on fall prevention.</p> <p>Methods</p> <p>An electronic literature search of selected comprehensive databases was performed to identify injurious falls definitions in published trials. Inclusion criteria were: RCTs on falls prevention published in English, study population ≥ 65 years, definition of injurious falls as a study endpoint by using the terms "injuries" and "falls".</p> <p>Results</p> <p>The search yielded 2089 articles, 2048 were excluded according to defined inclusion criteria. Forty-one articles were included. The systematic analysis of the methodology applied in RCTs disclosed substantial variations in the definition and methods used to measure and document injurious falls. The limited standardisation hampered comparability of study results. Our results also highlight that studies which used a similar, standardised definition of injurious falls showed comparable outcomes.</p> <p>Conclusions</p> <p>No standard for defining, measuring, and documenting injurious falls could be identified among published RCTs. A standardised injurious falls definition enhances the comparability of study results as demonstrated by a subgroup of RCTs used a similar definition. Recommendations for standardising the methodology are given in the present review.</p

Medial longitudinal arch development of school children : The College of Podiatry Annual Conference 2015: meeting abstracts

Background Foot structure is often classified into flat foot, neutral and high arch type based on the variability of the Medial Longitudinal Arch (MLA). To date, the literature provided contrasting evidence on the age when MLA development stabilises in children. The influence of footwear on MLA development is also unknown. Aim This study aims to (i) clarify whether the MLA is still changing in children from age 7 to 9 years old and (ii) explore the relationship between footwear usage and MLA development, using a longitudinal approach. Methods We evaluated the MLA of 111 healthy school children [age = 6.9 (0.3) years] using three parameters [arch index (AI), midfoot peak pressure (PP) and maximum force (MF: % of body weight)] extracted from dynamic foot loading measurements at baseline, 10-month and 22-month follow-up. Information on the type of footwear worn was collected using survey question. Linear mixed modelling was used to test for differences in the MLA over time. Results Insignificant changes in all MLA parameters were observed over time [AI: P = .15; PP: P = .84; MF: P = .91]. When gender was considered, the AI of boys decreased with age [P = .02]. Boys also displayed a flatter MLA than girls at age 6.9 years [AI: mean difference = 0.02 (0.01, 0.04); P = .02]. At baseline, subjects who wore close-toe shoes displayed the lowest MLA overall [AI/PP/MF: P < .05]. Subjects who used slippers when commencing footwear use experienced higher PP than those who wore sandals [mean difference = 31.60 (1.44, 61.75) kPa; post-hoc P = .04]. Discussion and conclusion Our findings suggested that the MLA of children remained stable from 7 to 9 years old, while gender and the type of footwear worn during childhood may influence MLA development. Clinicians may choose to commence therapy when a child presents with painful flexible flat foot at age 7 years, and may discourage younger children from wearing slippers when they commence using footwear

Effective self-regulated science learning through multimedia-enriched skeleton concept maps

This study combines work on concept mapping with scripted collaborative learning. Purpose: The objective was to examine the effects of self-regulated science learning through scripting students’ argumentative interactions during collaborative ‘multimedia-enriched skeleton concept mapping’ on meaningful science learning and retention. Programme description: Each concept in the enriched skeleton concept map (ESCoM) contained annotated multimedia-rich content (pictures, text, animations or video clips) that elaborated the concept, and an embedded collaboration script to guide students’ interactions. Sample: The study was performed in a Biomolecules course on the Bachelor of Applied Science program in the Netherlands. All first-year students (N=93, 31 women, 62 men, aged 17–33 years) took part in this study. Design and methods: The design used a control group who received the regular course and an experimental group working together in dyads on an ESCoM under the guidance of collaboration scripts. In order to investigate meaningful understanding and retention, a retention test was administered a month after the final exam. Results: Analysis of covariance demonstrated a significant experimental effect on the Biomolecules exam scores between the experimental group and the control, and the difference between the groups on the retention test also reached statistical significance. Conclusions: Scripted collaborative multimedia ESCoM mapping resulted in meaningful understanding and retention of the conceptual structure of the domain, the concepts, and their relations. Not only was scripted collaborative multimedia ESCoM mapping more effective than the traditional teaching approach, it was also more efficient in requiring far less teacher guidance
