Overview (debate)

An overview in policy debate is part of a speech which is flagged as not responding to the line-by-line arguments on the flow. An overview may be "global" if presented at the beginning of a speech or "local" if presented at the beginning of a position.

Overviews typically list the order a debater's speech will be given in. For instance, On-Case, Co-op Disadvantage, Spending Disadvantage, Weapon Disadvantage would be an expected overview.

Debaters will usually inform the judge where they will be giving an overview before they start a speech because it can make it harder to flow the speech. A small minority of judges dislike this practice and will start speech time when a debater starts giving this order.

Many judges dislike overviews because, since many are scripted before the round begins, they tend to be non-responsive or repetitive and are often long. However, most judges and coaches support the practice for arguments which cannot be placed anywhere on the line-by-line or that need to be flagged for their importance.

Product breakdown structure

In project management, a product breakdown structure (PBS) is a tool for analysing, documenting and communicating the outcomes of a project, and forms part of the product based planning technique.

The PBS provides ''an exhaustive, hierarchical tree structure of deliverables (physical, functional or conceptual) that make up the project, arranged in whole-part relationship'' (Duncan, 2015).

This diagrammatic representation of project outputs provides a clear and unambiguous statement of what the project is to deliver.

The PBS is identical in format to the work breakdown structure (WBS), but is a separate entity and is used at a different step in the planning process. The PBS precedes the WBS and focuses on cataloguing all the desired outputs (products) needed to achieve the goal of the project. This feeds into creation of the WBS, which identifies the tasks and activities required to deliver those outputs. Supporters of product based planning suggest that this overcomes difficulties that arise from assumptions about what to do and how to do it by focusing instead on the goals and objectives of the project - an oft-quoted analogy is that PBS defines where you want to go, the WBS tells you how to get there.

Product (category theory)

In category theory, the product of two (or more) objects in a category is a notion designed to capture the essence behind constructions in other areas of mathematics such as the cartesian product of sets, the direct product of groups, the direct product of rings and the product of topological spaces. Essentially, the product of a family of objects is the "most general" object which admits a morphism to each of the given objects.

Definition

Let C be a category with some objects X₁ and X₂. An object X is a product of X₁ and X₂, denoted X₁ × X₂, if it satisfies this universal property:

The unique morphism f is called the product of morphisms f₁ and f₂ and is denoted < f₁, f₂ >. The morphisms π₁ and π₂ are called the canonical projections or projection morphisms.

Above we defined the binary product. Instead of two objects we can take an arbitrary family of objects indexed by some set I. Then we obtain the definition of a product.

An object X is the product of a family (X_i)_i∈I of objects iff there exist morphisms π_i : X → X_i, such that for every object Y and a I-indexed family of morphisms f_i : Y → X_i there exists a unique morphism f : Y → X such that the following diagrams commute for all i∈I:

Defence Housing Authority, Karachi

The Defence Housing Authority, Karachi, also known as the Pakistan Defence Officers Housing Authority, Karachi, or DHA, Karachi, is an upscale real estate and property development organisation administered by the Pakistan Army which develops housing for current and retired military personnel. It is an suburban Housing development in metropolitan Karachi, Sindh, Pakistan.

History and administration

The Authority came into existence through Presidential Order No.7 of 1980 and was later approved by the National Assembly of Pakistan. The Authority is spread over 8,852 acres (35.82 km²) and provides civic facilities to millions of residents. The efforts to develop DHA have been fruitful, signified by growth oriented high class living valuesThe housing projects are planned to cover every aspect of healthy living and contain parks, educational institutions and clubs. The organizational matters are attended by Secretary, Chief Engineer, Directors and a committed and work force to ensure smooth running of the organization.
