Suzuki-Miyaura mediated biphenyl synthesis: a spotlight on the boronate coupling partner
The biaryl motif is found in many natural and synthetic products that display a wide range of biological activities. This explains why biphenyls are widely encountered in medicinal chemistry as a privileged scaffold. The palladium-catalysed Suzuki-Miyaura (SM) coupling is one of the most important …

A Consideration of Signal Processing for Spotlight Synthetic Aperture Radar (Ambiguity Functions)
An analysis of spotlight mode synthetic aperture radar (SAR) imaging was carried out using a model based solely on the recognizable similarity it shares with tomographic reconstruction. Doppler effects were relegated to a pre-processing step. Results of this investigation included a determination …

A non-linear spotlight line transect method for estimating white-tailed deer population densities
… rely upon density estimates obtained from spotlight strip transect surveys to regulate annual harvest Yet, density estimates from the standard spotlight strip transect method are known to be inaccurate in areas of dense vegetation, and alternatives such as the Hahn method, mark-recapture, …

Out of the Spotlight and into the Shadows: An Examination of Communication about Adolescent Girls on Music Television.
<p>This study examines portrayals of adolescent girls on Music Television (MTV). A content analysis of 26 hours of MTV programming was conducted and analyzed using quantitative and qualitative methods. Analyzed programming was shown August-November 2001. Dates were chosen randomly; times were …

Governments in the spotlight? : on the use and impacts of freedom of information laws and proactive publication of government data
In election times, political parties promise in their manifestos to pass reforms increasing access to government information to root out corruption and improve public service delivery. Scholars have already offered several fascinating explanations of why governments adopt policies that constrain …

Population Estimation Procedures For Elk and Deer in the Black Hills, South Dakota: Development of a Sightability Model and Spotlight Survey
… to quantify visual obstruction objectively. Spotlight surveys can be used as an alternative method to construct density estimates of ungulates when cost prohibits annual use of aerial surveys. Although spotlight surveys have been used by South Dakota Game, Fish and Parks in the past, …

Exploring the Factors that Impact on the Attitude to Purchase: A spotlight on counterfeit luxury handbags among Durban's emergent Black Middle-class Females
Increased sales of counterfeit luxury branded handbags are a significant transnational concern. Research effort concerning understanding this purchase behaviour has largely been contextualised outside of Africa, with varying results relating to the impact of attitude on the purchase decision-making …

‘Restor(y)ing their position in the spotlight, please welcome back on stage… Postgraduate Students who teach… or Graduate Teaching Assistants... or Teaching Postgrads… or…’
… of these postgraduate students and shines a spotlight on their occupational positioning and identity within the sector. Underpinned by a poststructuralist stance, which sets out to deconstruct existing structures, the study problematizes the concept of Graduate Teaching Assistants (GTAs) and …

An assessment of whether the critical minerals boom and green transition can be leveraged for Zambia's industrialisation and economic development: spotlight on the Copper Mining Sector
This study assesses whether Zambia can leverage the critical minerals boom and the global green transition to drive its industrialisation and economic development. As a major copper producer, Zambia holds strategic importance in supplying minerals essential for renewable technologies such as …

Volunteer Spotlighting: Costly Signaling to Promote Volunteerism
… social media. I predicted that the costliness of spotlighted behavior and the target signal clarity (i.e., individual vs. group spotlight) would interact with participants’ dispositional dominance and prestige-based status motives to influence volunteerism interest. To explore these associations, …

The Phase Gradient Autofocus Algorithm with Range Dependent Stripmap SAR
… Autofocus (PGA) algorithm is widely used in spotlight mode SAR for motion compensation. The Maximum Likelihood PGA (ML PGA) algorithm has been shown to be a superior autofocus method. The PGA is restricted to high altitude aircraft. Since lower altitude SARs have significant range …

The Effects of Stimuli Type, Size, and Articulation on Estimating the Luminance Contrast of Real and CRT Targets
… constancy would increase as stimuli moved from a spotlight, to paper, and finally to a CRT monitor. Lightness constancy was also expected to increase with articulation, and to vary as stimuli sized increased or decreased. Two separate experiments were conducted with a total of 80 college students …

Evaluation of Methodology Use to Estimate Population Size, Sex and Age Ratios, and Mortality of White-tailed and Mule Deer in the Missouri River Breaks Region of South Dakota
… fawn:doe and buck:doe ratios estimated from spotlight surveys. Number of deer observed during spotlight and dusk/dawn surveys were different for white-tailed deer (P= 0.025) and all deer combined (P=0.018); the number of mule deer observed differed at£= 0.058 between spotlight and dusk/dawn …

Investigation of topics in radar signal processing
… algorithm proposed by W. Lawton for spotlight-mode synthetic aperture radar (SAR). The spatial domain image is produced through a series of convolutions and DFTs, all performed using FFTs. We show that the algorithm implements a form of trapezoidal-to-Cartesian interpolation followed …

A Study of the Leadership of High-Poverty, High-Performing Schools Through the Lens of Moral Leadership
… schools studied were recipients of the Illinois Spotlight Schools Award in 2007. Illinois Spotlight Schools serve a school community where at least: 50% of students were identified as low-income; 60% of students met or exceeded standards in both reading and mathematics as measured on the Illinois …

Density, Movements, and Habitat Use of White-Tailed Deer at Sand Lake National Wildlife Refuge, South Dakota
… density estimates using infrared sensing and spotlight surveys indicated that spotlight surveys underestimated deer density. A correction factor (1.38) was calculated to increase accuracy of spotlight surveys, which may be conducted annually at minimal cost. Female deer that were hunted in …
