Technologies and Practices to Reduce Impacts of Artificial Light at Night on Nightime Scenery

Artificial light at night (ALAN) adversely impacts nighttime scenery values. Current standards for LED lighting have led to brighter nighttime lighting, using color temperatures that are more harmful to human and ecological health, and which create an exponentially larger landscape impact than historical ALAN technologies. Less-harmful LED lighting and other existing technologies can be used to control artificial light at night, creating safe and pleasing perceptual nighttime experiences while minimizing ecological impacts. Minimizing the impact of artificial light at night requires understanding new lighting technologies, and management practices that extend beyond current lighting standards. This is crucial in order to sustain and protect the visual and cultural qualities of the landscape, and the ecological functions that we enjoy and depend upon. This paper will outline how the human body perceives and is affected by light, a key component to the success of implementing light pollution mitigation; discuss existing and evolving fixture programming technologies, and present challenges faced and lessons learned in implementing new lighting standards that support visual resource stewardship

Is it Really all about the Money?: Motivating Employees in the 21st Century

Motivation has been defined as an emotion or desire operating on the will and causing it to act. In this respect, ‘motivations provide the motor for behavior,’ and according to Pincus, motivation as a psychological construct has played many roles as paradigms have risen and fallen over the decades (2004). To obtain a better understanding of motivation in the twenty-first century, this paper focuses on what motivation is, the role goals play in motivation, how motivation can be maintained, the impact of technology on motivation, the practical implications of needs-based motivation theories, and the concept of over-motivation

Exploring disparities in acute myocardial infarction events between Aboriginal and non-Aboriginal Australians: roles of age, gender, geography and area-level disadvantage

We investigated disparities in rates of acute myocardial infarction (AMI) between Aboriginal and non-Aboriginal people in the 199 Statistical Local Areas (SLAs) in New South Wales, Australia. Using routinely collected and linked hospital and mortality data from 2002 to 2007, we developed multilevel Poisson regression models to estimate the relative rates of first AMI events in the study period accounting for area of residence. Rates of AMI in Aboriginal people were more than two times that in non-Aboriginal people, with the disparity greatest in more disadvantaged and remote areas. AMI rates in Aboriginal people varied significantly by SLA, as did the Aboriginal to non-Aboriginal rate ratio. We identified almost 30 priority areas for universal and targeted preventive interventions that had both high rates of AMI for Aboriginal people and large disparities in rates

TeV Scale Leptogenesis in B-L Model with Alternative Cosmologies

In TeV scale B-L extension of the standard model with inverse seesaw, the Yukawa coupling of right-handed neutrinos can be of order one. This implies that the out of equilibrium condition for leptogenesis within standard cosmology is not satisfied. We provide two scenarios for overcoming this problem and generating the desired value of the baryon asymmetry of the Universe. The first scenario is based on extra-dimensional braneworld effects that modify the Friedman equation. We show that in this case the value of the baryon asymmetry of the Universe constrains the five-dimensional Planck mass to be of order O(100) TeV. In the second scenario a non-thermal right-handed neutrino produced by the decay of inflaton is assumed. We emphasize that in this case, it is possible to generate the required baryon asymmetry of the Universe for TeV scale right-handed neutrinos.Comment: 13 pages, 2 figure

A Successful Live Birth Through in vitro Fertilization Program After Conservative Treatment of FIGO Grade I Endometrial Cancer

Infertile women with chronic anovulation are prone to be exposed to unopposed estrogen stimulation and have the high risk of being suffering from endometrial hyperplasia or even endometrial carcinoma. A few reports have suggested that nulliparous young women (under 40 yr of age) with endometrial carcinoma could be treated conservatively to preserve fertility and succeed the live birth. We report on a 36-yr-old woman who received conservative treatment of endometrial carcinoma (stage I, grade 1) by curettage and progestin. After megestrol medication of total 71,680 mg during 24 weeks, we found the regression of endometrial lesion by curettage and hysteroscopic examination. Then we decided to perform in vitro fertilization program. Two embryos were transferred and heterotypic pregnancy was diagnosed 27 days after embryo transfer. After right salpingectomy, she received routine obstetrical care and delivered by cesarean section at 38 weeks in gestational periods. Two years after delivery, she is healthy without any evidence of recurrent disease. The fertility preserving treatment is an option in endometrial cancer patients if carefully selected, and assisted reproductive technologies would be helpful

Resistance to Schistosoma mansoni is correlated with the number of spreading granulocytes in Biomphalaria glabrata

Molluscan internal defenses rely heavily on circulating hemocytes. In most cases, encounters with large foreign bodies result in recognition by hemocytes followed by spreading of these defense cells over the object’s surface. The resulting encapsulation concentrates the force of the hemocytes’ assault on the foreign object. B. glabrata snail lines obtained by self-fertilization of isolated 13-16-R1 [Oregon] individuals have yielded multiple inbred families in which genes are fixed at ~88% of the loci. Among the phenotypic traits that we have measured in 20 of these families are susceptibilities of snails to the PR1 [Oregon] strain of Schistosoma mansoni, and hematocrits of quickly spreading granulocytes present in the hemolymph.  Higher numbers of these cells predict a snail phenotype that is resistant to S. mansoni infection. Both resistant and susceptible snails are found in families with intermediate hematocrits. We infer that within the parental 13-16-R1 population hemocyte numbers are varied. When sufficiently numerous, a snail’s hemocytes can generally prevent parasitic infection. At lower hematocrits, a more complex set of variables interact to determine the outcome of an infection

Space Systems: Emerging Technologies and Operations

SPACE SYSTEMS: EMERGING TECHNOLOGIES AND OPERATIONS is our seventh textbook in a series covering the world of UASs / CUAS/ UUVs. Other textbooks in our series are Drone Delivery of CBNRECy – DEW Weapons: Emerging Threats of Mini-Weapons of Mass Destruction and Disruption (WMDD); Disruptive Technologies with applications in Airline, Marine, Defense Industries; Unmanned Vehicle Systems & Operations On Air, Sea, Land; Counter Unmanned Aircraft Systems Technologies and Operations; Unmanned Aircraft Systems in the Cyber Domain: Protecting USA’s Advanced Air Assets, 2nd edition; and Unmanned Aircraft Systems (UAS) in the Cyber Domain Protecting USA\u27s Advanced Air Assets, 1st edition. Our previous six titles have received considerable global recognition in the field. (Nichols & Carter, 2022) (Nichols et al., 2021) (Nichols R. K. et al., 2020) (Nichols R. et al., 2020) (Nichols R. et al., 2019) (Nichols R. K., 2018) Our seventh title takes on a new purview of Space. Let\u27s think of Space as divided into four regions. These are Planets, solar systems, the great dark void (which fall into the purview of astronomers and astrophysics), and the Dreamer Region. The earth, from a measurement standpoint, is the baseline of Space. It is the purview of geographers, engineers, scientists, politicians, and romantics. Flying high above the earth are Satellites. Military and commercial organizations govern their purview. The lowest altitude at which air resistance is low enough to permit a single complete, unpowered orbit is approximately 80 miles (125 km) above the earth\u27s surface. Normal Low Earth Orbit (LEO) satellite launches range between 99 miles (160 km) to 155 miles (250 km). Satellites in higher orbits experience less drag and can remain in Space longer in service. Geosynchronous orbit is around 22,000 miles (35,000 km). However, orbits can be even higher. UASs (Drones) have a maximum altitude of about 33,000 ft (10 km) because rotating rotors become physically limiting. (Nichols R. et al., 2019) Recreational drones fly at or below 400 ft in controlled airspace (Class B, C, D, E) and are permitted with prior authorization by using a LAANC or DroneZone. Recreational drones are permitted to fly at or below 400 ft in Class G (uncontrolled) airspace. (FAA, 2022) However, between 400 ft and 33,000 ft is in the purview of DREAMERS. In the DREAMERS region, Space has its most interesting technological emergence. We see emerging technologies and operations that may have profound effects on humanity. This is the mission our book addresses. We look at the Dreamer Region from three perspectives:1) a Military view where intelligence, jamming, spoofing, advanced materials, and hypersonics are in play; 2) the Operational Dreamer Region; whichincludes Space-based platform vulnerabilities, trash, disaster recovery management, A.I., manufacturing, and extended reality; and 3) the Humanitarian Use of Space technologies; which includes precision agriculture wildlife tracking, fire risk zone identification, and improving the global food supply and cattle management. Here’s our book’s breakdown: SECTION 1 C4ISR and Emerging Space Technologies. C4ISR stands for Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance. Four chapters address the military: Current State of Space Operations; Satellite Killers and Hypersonic Drones; Space Electronic Warfare, Jamming, Spoofing, and ECD; and the challenges of Manufacturing in Space. SECTION 2: Space Challenges and Operations covers in five chapters a wide purview of challenges that result from operations in Space, such as Exploration of Key Infrastructure Vulnerabilities from Space-Based Platforms; Trash Collection and Tracking in Space; Leveraging Space for Disaster Risk Reduction and Management; Bio-threats to Agriculture and Solutions From Space; and rounding out the lineup is a chapter on Modelling, Simulation, and Extended Reality. SECTION 3: Humanitarian Use of Space Technologies is our DREAMERS section. It introduces effective use of Drones and Precision Agriculture; and Civilian Use of Space for Environmental, Wildlife Tracking, and Fire Risk Zone Identification. SECTION 3 is our Hope for Humanity and Positive Global Change. Just think if the technologies we discuss, when put into responsible hands, could increase food production by 1-2%. How many more millions of families could have food on their tables? State-of-the-Art research by a team of fifteen SMEs is incorporated into our book. We trust you will enjoy reading it as much as we have in its writing. There is hope for the future.https://newprairiepress.org/ebooks/1047/thumbnail.jp

Committing to ecological restoration: Efforts around the globe need legal and policy clarification

At the September 2014 United Nations Climate Summit, governments rallied around an international agreement—the New York Declaration on Forests—that underscored restoration of degraded ecosystems as an auspicious solution to climate change. Ethiopia committed to restore more than one-sixth of its land. Uganda, the Democratic Republic of Congo, Guatemala, and Colombia pledged to restore huge areas within their borders. In total, parties committed to restore a staggering 350 million hectares by 2030.Fil: Suding, Kathering. State University Of Colorado-boulder; Estados UnidosFil: Higgs, Eric.

A single-column model ensemble approach applied to the TWP-ICE experiment

Single-column models (SCM) are useful test beds for investigating the parameterization schemes of numerical weather prediction and climate models. The usefulness of SCM simulations are limited, however, by the accuracy of the best estimate large-scale observations prescribed. Errors estimating the observations will result in uncertainty in modeled simulations. One method to address the modeled uncertainty is to simulate an ensemble where the ensemble members span observational uncertainty. This study first derives an ensemble of large-scale data for the Tropical Warm Pool International Cloud Experiment (TWP-ICE) based on an estimate of a possible source of error in the best estimate product. These data are then used to carry out simulations with 11 SCM and two cloud-resolving models (CRM). Best estimate simulations are also performed. All models show that moisture-related variables are close to observations and there are limited differences between the best estimate and ensemble mean values. The models, however, show different sensitivities to changes in the forcing particularly when weakly forced. The ensemble simulations highlight important differences in the surface evaporation term of the moisture budget between the SCM and CRM. Differences are also apparent between the models in the ensemble mean vertical structure of cloud variables, while for each model, cloud properties are relatively insensitive to forcing. The ensemble is further used to investigate cloud variables and precipitation and identifies differences between CRM and SCM particularly for relationships involving ice. This study highlights the additional analysis that can be performed using ensemble simulations and hence enables a more complete model investigation compared to using the more traditional single best estimate simulation only
