Policy biased science is increasingly common in the scientific enterprise and this helps undermine the credibility of science and scientists in public policy debates. Specifically, often scientific information is presented to the public and decision-makers that is infused with hidden policy preferences. Using normative science in policy deliberations is not merely a form of policy advocacy, but it is stealth advocacy. Normative science is a corruption of science and should not be tolerated in the scientific community — without exception. Scientific information must remain a cornerstone of public policy decisions about natural resource and ecological issues, but I offer cautionary guidance to scientists: become involved with policy issues and deliberations, but play the proper role. Provide facts, probabilities, and analysis, but avoid slipping into normative science. Scientists have much to offer the public and decision-makers, but also have much to lose when they practice stealth policy advocacy.

Imagine que usted debe diseñar un eje cilíndrico giratorio para levantar cubetas de cemento con un peso de 800 N, desde el suelo hasta una azotea a 78.0 m sobre el suelo. Las cubetas se colgarán de un gancho en el extremo libre de un cable que se enrolla en el eje; al girar este eje, las cubetas ascienden. a) ¿Qué diámetro debe tener el eje para levantar las cubetas con rapidez constante de 2.00 cm>s mientras gira a 7.5 rpm? b) Si el eje debe impartir a las cubetas una aceleración hacia arriba de 0.400 m>s2, ¿qué aceleración angular deberá tener el eje? EJERCICIO 52 Una escalera uniforme de 2.00 m de longitud y masa de 9.00 kg está apoyada contra un muro vertical formando un ángulo de 538 con el piso. Un trabajador empuja la escalera contra la pared hasta que queda vertical. ¿Cuánto trabajo realizó esa persona contra la gravedad? 9.53. Una cuerda uniforme de 3.00 kg y 24.0 m de longitud está en el suelo en la cima de un risco vertical. En la cima un alpinista desciende hasta la mitad de la cuerda, para ayudar a su compañero a subir el acantilado. ¿Cuál fue el cambio en la energía potencial de la cuerda durante esta maniobra? EJERCICIO 64 Dibuje una rueda que yace en el plano del papel y gira en sentido antihorario. Elija un punto en el borde y dibuje un vector del centro de la rueda a ese punto. a) ¿Qué dirección tiene b) Demuestre que la velocidad del punto es c) Demuestre que la aceleración radial del punto es (véase el ejercicio 9.28)

The following second part of our analysis provides historical background information in order to better understand future options of the Kurds. We explain here in some detail why so far in contemporary history, virtually all efforts failed to achieve legitimate national rights for the Kurds and why they could and should not be repeated in the future. We basically show in sketched small historical chapters that Kurds to date could only win limited national rights, like some forms of autonomous regional self-rule. The reasons for that are in many aspects. Firstly, because they were used over centuries both by dominant central as well as foreign powers as proxies for their interests and also cooperated with them for own split aims. Second, because Kurds are chronically divided, constantly at loggerheads, disunited (Sheikhmous, 1992 & 2013: " united in disunity ") and fragmented. Thirdly, although they remain a considerable force of stability in Eurasia and the Middle East and are indeed underway to democracy they are still unable to come true majority rule of Western democracies. And last but not least, because they lack experience governing themselves and diplomacy to secure their own national rights with one strong united voice.

One of the most important automotive systems is suspension. The primary purpose is to protect the driver from shocks from the road. In addition to providing proper wheel travel and load transfer, secondary functions also include lateral stability and ergonomics and driver comfort. Vehicles with all-terrain capabilities are built to tackle any surface. Stability, vehicle behavior, and driver comfort are the main issues because the vehicle is designed to operate on various types of terrain. The paper's primary goal was to develop and optimize the front suspension wishbone for a BAJA (ATV) vehicle. The purpose of this study is to analyze the entire suspension system of an ATV vehicle to enhance wheel handling and stability. The entire system was made to be strong enough to absorb shocks from the rough terrain that ATVs are typically used on. Calculations were used to design the springs, and SOLIDWORKS was used to design the components. The front and rear systems were simulated using Lotus software, and the components were examined using commercial FEA software from ANSYS. The steering and suspension system's pivot point, known as the steering knuckle, enables the steering arm to turn the front wheels. The knuckle is put to the test in a variety of loading conditions, including bump, cornering, and braking.
