WHOSE PREFERENCES ARE REVEALED IN HOURS OF WORK?

How Are Preferences Revealed?

Revealed preferences are tastes that rationalize an economic agent's observed actions. Normative preferences represent the agent's actual interests. It sometimes makes sense to assume that revealed preferences are identical to normative preferences. But there are many cases where this assumption is violated. We identify five factors that increase the likelihood of a disparity between revealed p...

Modules whose direct summands are FI-extending

‎A module $M$ is called FI-extending if every fully invariant submodule of $M$ is essential in a direct summand of $M$‎. ‎It is not known whether a direct summand of an FI-extending module is also FI-extending‎. ‎In this study‎, ‎it is given some answers to the question that under what conditions a direct summand of an FI-extending module is an FI-extending module?

Some Families of Graphs whose Domination Polynomials are Unimodal

Let $G$ be a simple graph of order $n$. The domination polynomial of $G$ is the polynomial $D(G, x)=sum_{i=gamma(G)}^{n} d(G,i) x^{i}$, where $d(G,i)$ is the number of dominating sets of $G$ of size $i$ and $gamma(G)$ is the domination number of $G$. In this paper we present some families of graphs whose domination polynomials are unimodal.

Manpower and hours of work agreements are complementary.

Severe Raynaud's phenomenon can result in ulceration of the finger tips. Digital ulceration or gangrene may also be caused by non-vasospastic conditions. Emboli may be discharged from the fibrillating atrium, the ventricle after a myocardial infarction, or from an aneurysm of thhe subclavian artery. Arteriovenous malformations in the hand can cause enough shunting of blood to result in distal i...
