Batten disease, otherwise known as Neuronal Ceroid Lipofuscinosis, is the name given to a family of rare genetic conditions of the nervous system. There are over 400 variants in 13 different genes known to cause Batten disease and consequently, several different forms of the condition. The exact symptoms, time of onset, and severity vary by the form, but most develop in childhood. Common symptoms include seizures, vision loss, cognitive and motor decline, and dementia. As new therapies are being developed, its become imperative to diagnose the condition as early as possible. Three forms of Batten disease, referred to as CLN1, CLN2, and CLN10 disease, are caused by loss-of-function variants in the genes encoding lysosomal enzymes PPT1, TPP1 and cathepsin D, respectively. Enzymatic assays can be used to diagnose these different forms. In these assays, patient samples are mixed with a synthetic substrate. The substrate can be cleaved by the corresponding enzyme, releasing a fluorescent molecule which can then be detected. A single enzymatic assay is performed for each of the three enzymes listed earlier to help provide a rapid and reliable diagnosis. Which of the following results would suggest a diagnosis of CLN2 disease?.

Gestin de recursos humanos en Rusia: el dilema de un estadounidense Jack Daly lleg a Novgorod, en el noroeste de Rusia, en la primavera de 2003. Trabajaba para Starline Inc., un importante fabricante de alimentos de EE. UU., y haba sido designado para dirigir su subsidiaria rusa de propiedad total. Starline Rusia era una planta de fabricacin de tamao mediano con 280 empleados. Se haba establecido en 1994 y tena una organizacin funcional con el nivel superior integrado por expatriados estadounidenses y con mandos intermedios contratados localmente. Los estadounidenses solan ocupar puestos a corto plazo: de dos a cuatro aos para el presidente (Daly) y de seis a doce meses para tres vicepresidentes de produccin, marketing y ventas. Todos tenan experiencia internacional, pero ninguno haba trabajado antes en Rusia o Europa del Este. Antes de mudarse a Novgorod, recibieron breves sesiones informativas culturales y un curso intensivo de ruso de tres semanas. Los gerentes rusos eran principalmente veinteaeros, bien educados pero con poca experiencia gerencial y sin experiencia ms all de la regin. Los empleados de cuello azul provenan de diversos entornos, pero la mayora haba experimentado serias dificultades financieras antes de unirse a Starline. Un tercio haba estado desempleado; el resto haba sido empleado pero no haba recibido salario durante meses. Su salario promedio en Starline era de alrededor de US$200 al mes, alrededor de un 30% ms que el salario promedio en Rusia. La nueva empresa se haba topado rpidamente con problemas de hurto, hurto y paradas de produccin. A fines de 1999, cuando lleg el predecesor de Daly, Tom Stark, el robo era un problema importante, y se pensaba que alrededor del 30% de los trabajadores de produccin estaban involucrados. Aunque el ausentismo era raro, los retrasos y los descansos no programados eran comunes. La productividad estaba muy por debajo de la de otras fbricas de Starline en Asia y Occidente. Tambin hubo problemas con los gerentes rusos, que mostraron poca iniciativa, ignoraron las instrucciones y no abordaron los problemas en el futuro. Tom Stark haba respondido inicialmente de dos maneras. Haba introducido sistemas de control ms estrictos, incluidos los controles de seguridad y los registros de equipaje llevados a cabo por los administradores locales. Y haba creado un sistema informal de recompensas basado en los que se utilizan tradicionalmente en las empresas rusas y en los que utiliza Starline en algunos pases en desarrollo. Cada mes, el gerente y el supervisor con mejor desempeo recibieron insignias especiales, recibieron cartas de agradecimiento de Stark y colocaron sus fotografas en la pared. Sin embargo, las iniciativas tuvieron poco efecto y, en 2002, Stark contrat a un alto gerente ruso para supervisar el equipo de gestin ruso. Nikolai Rubkoff tena cincuenta y tantos aos y anteriormente haba sido director gerente de una gran planta de tractores, e introdujo un estilo de gestin completamente nuevo.

For each of the statements below, please answer true or false and then justify your answer with a brief explanation. 4.1 One way to make the payback period method just as valid as the NPV (net present value) method is to discount cash flows from the same project to today's dollars. (4 points) 4.2 The main difference between $1 today and $1 later is the interest factor. Thus, projects with higher cash flows at the start of the project are better projects. (4 points) 4.3 To determine cash flows, depreciation expense must be added to net income because it does not constitute a cash outflow. (4 points) 4.4 The analysis period of a project (the investment horizon) consists of the period of time over which it is possible to generate interesting cash flows for the company. (4 points) 4.5 The criteria of NPV (net present value) and IRR (internal rate of return) rank in the same order the viability of several mutually exclusive projects. (4 points).

A researcher is investigating the effect of background noise on classroom performance for children aged 10 to 12. One class of N = 15 students who listens to calming music each day while working on arithmetic problems is chosen as the experimental group. Another class of N = 16 students serves as a control group with no music. Accuracy scores are measured for each child, and the average for students in the music condition is X = 86.4 with SS = 1550. For the no-music condition, the average is X = 78.8 with SS = 1235..

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
