Beginner: this doesn't make sense to me


Do you need and "empty" script tag in the head to run scripts that are in the body?  Also, can you run JQuery scripts if they're in the <head> tag?  The first sample only works if the JQuery script is in the form (and body) tag, not in the head - even if I add $(document).ready(function() { });

This works

<head runat="server">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" />
<script type="text/javascript">
<form id="form1" runat="server">
<a href="">Here is a link</a>
<script type="text/javascript">
$('a').click(function () {
alert("you clicked me!");


This doesn't work.  Notice I removed the second <script> tag from the head

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="serve

SELECT     Message, CreateDate, AccountId, AlertTypeId
FROM       dbo.Alerts
SELECT     TOP (100) PERCENT Status, CreateDate, AccountId,
                          (SELECT     10 AS Expr1) AS AlertTypeId
FROM         dbo.StatusUpdates
WHERE AccountId = PassedInParameter

I have been going about trying to convert the above into a LINQ method and am having problems with return types.
As the above SQL illustrates, I am querying two distinct LINQ tables - Alerts and StatusUpdates -
and then attempting to perform a Union on them. In order to do the union in LINQ, I have to have agreeing types. So, I
am using "var" to make the results of "alerts" and "updates" generic before the union.  

public IList GetStatusUpdatesAsAlertsByAccountId<T>(Int32 accountId)
            using (WorkbookDataContext dc = _conn.GetCont
