The SECD machine is a prototype abstract machine for higher-order functional languages using the by-value strategy to evaluate lambda “calculus” expressions. It determines how to compute the function expression before evaluating the function expression.

2a) Briefly explain the acronym SECD.

What are the three main layers (abstract) that make up a computer ?

(It is possible to be more detailed, but you can simplify to three basic layers in most computer)

A Application, System, Hardware

B Software, Operations, Architecture

C Programs, Algorithms, Transistors

QUESTION 2 (20) Below is the title and abstract of an article which was published in the Academy of Management Journal, Vol. 61, No. 6, page 2265 – 2295. Critically reflect on the abstract and answer the questions that follow. Entrepreneurial Imaginativeness in New Venture Ideation Alexander S. Kier and Jeffery S. McMullen Abstract Although theories of entrepreneurial action regularly acknowledge the importance of imagination, the ability is rarely defined or measured, and thus effectively treated as uniform in degree and type. Using a creative problem-solving lens, we identify and measure three different cognitive skills—creative, social, and practical imaginativeness—that vary across individuals. Each skill combines the ability of imagination with the knowledge needed to mentally simulate various task-related scenarios used in generating and selecting ideas for new value creation. We then conduct a quasi-experiment to examine each skill’s relative effect on new venture ideation. We find that the three imaginativeness skills vary across individuals and that they predict new venture idea quantity and quality differently over and above the effects of motivation, knowledge, and experience. We conclude with implications for theory development in entrepreneurship and creative problem-solving. REQUIRED: 2.1 Based on the content of the abstract, identify and discuss the type of research conducted by Kier and McMullen (2018), and explain the main deductive theory underpinning the research and the contributions made to the body of knowledge. (5) 2.2 Elaborate on the motivation for this paper, highlighting the focus of inquiry (i.e. the broad question of interest). (4) 2.3 Highlight the independent variables and dependent variable identified and measured in the study and the likely inferential tests conducted by Kier and McMullen (2018). (4) 2.4 Comment on the strategic relevance of Kier and McMullen’s (2018) findings and highlight TWO (2) key shortcomings of most quasi-experiments. (4) 2.5 Based on Kier and McMullen’s (2018) findings, suggest one practical recommendation that you would offer to potential funders of start-ups.

(The Colorable interface) Design an interface named Colorable with a void method named howToColor(). Every class of a colorable object must implement the Colorable interface. Design a class named Square that extends GeometricObjectand implements Colorable. Design another class named Trianglethat extends GeometricObjectand implements Colorable. Implement howToColor inSquareto display the message Color all four sides. ImplementhowToColor inTriangleto display the message Color all three sides.

Draw a UML diagram that involves Colorable, Square, Triangle, and GeometricObject.

Write a test program that creates an array of five GeometricObjects. For each object in the array, display its area and invoke its howToColor method if it is colorable.
