J2EE a la Carte: Role-Based Security |
EJB 3.0 has also defined some annotations to do role-based security. JBoss AOP builds on this so that you can apply role-based security to any field or method (static or member) as well as any constructor. |
import org.jboss.aspects.security.*; |
@SecurityDomain("LDAP Repository") |
public class Foo |
@Permissions({"admin"}) public Foo() {} |
@Permissions({"developer"}) public static int status; |
@Permissions({"anybody"}) public static void doSomething() {...} |
EJB Evolution |
As AOP matures along with the EJB specification, what I really hope happens is that the annotations defined in the EJB specification will be usable in any context as new adjectives to the Java language, rather than their limited constricted use within session beans. Imagine a truly stateless bean being just a set of st... |
public MySessionBean |
@Tx(TxType.REQUIRED) public static doSomething() {...} |
Anyways, this talk of AOP and EJB is probably for EJB 4.0. |
Instead of limiting J2SE 5.0 annotations for use with code generation, annotations and AOP can be combined to give new power to framework developers. The combination allows developers to define new Java syntax that actually has behavior attached to it. Basically, the ability to extend the Java language in a typesafe wa... |

Mechanic's lien |
A mechanic's lien is a security interest in the title to property for the benefit of those who have supplied labor or materials that improve the property. The lien exists for both real property and personal property. In the realm of real property, it is called by various names, including, generically, construction lien... |
Reasons for existence |
With respect to real property, mechanic's liens are purely statutory devices that exist in every state. The reason they exist is a legislative public policy to protect the contractors. More specifically, the state legislatures have determined that, due to the economics of the construction business, contractors and subc... |
Vehicular Definition of a lien sale |
State of California,If the vehicle's value is $4,000 or less, the registered and legal owners of record will be notified by the party conducting the lien. If the vehicle's value is greater than $4,000, DMV notifies all interested parties. You can call (916)-657-7617 between the hours of 8 a.m. and 5 p.m. if you have qu... |
Mechanic's liens exist to secure payment for services, labor and material on both personal and real property. However, the creation and enforcement mechanisms differ depending on whether real or personal property is involved. The law of mechanic's liens on real property governs the creation and enforcement of these lie... |
Creation and Enforcement - Personal property |
The English common law recognized mechanic's liens respecting only personal property. The lien was created by the fact of the artisan working on the personal property item or attaching additional material to it. However, to maintain the lien, the artisan had to retain possession of the article until he or she was paid.... |
Some 34 states now appear to have statutes providing for mechanic's liens on personal property |
Creation, Perfection, Priority and Enforcement - Real property |
Mechanic's liens on the title to real property are exclusively the result of legislation. Each state has its own laws regarding the creation and enforcement of these liens, but, overall, there are some similar elements among them. |
Real property of the government (public property) is ordinarily not subject to the claims of private parties. Therefore, unless the state specifically so provides, mechanic's liens do not attach to the title owned by the state or its administrative subdivisions, such as cities. Similarly, mechanic's liens under state l... |
Creation and perfection |
Under the statutes, the lien is usually created by the performance of labor or the supplying of material that improves the property. Just what type of contribution counts as a valid basis for a mechanics lien varies, depending on the particular state statute that applies. Some common examples are: |
* Laborers, carpenters, electricians, and plumbers working on the project site; |
* Lumber yards, plumbing supply houses and electrical suppliers; |
* Architects and civil engineers who drew up the construction plans and specifications; and |
* Offsite fabricators of specialty items that are ultimately incorporated into the project. |
Often, there is no simple dividing line that is useful in every state, or even in every case, for determining this eligibility. Deciding whether a party has a legitimate lien right may depend on examining court cases that have either upheld or rejected lien claims in the same state. |
Unlike other security interests, in most states, mechanic's liens are given to contractors and material suppliers who may or may not have a direct contractual agreement with the owner of the land. In fact, this is often the norm because in most cases, the owner of the land contracts only with a general contractor (ofte... |
However, to have an enforceable lien, it usually must be "perfected." This means that the holder of the lien must comply with the statutory requirements for maintaining and enforcing the lien. These requirements, which contain time limits, are generally as follows: |
*Providing the required preliminary notice to the property owner disclosing the entitlement to the lien (some states). |
*Filing notices of commencement of work (some states). |
*Filing notices in the required public records offices of the intention to file a lien if unpaid (some states). |
*Filing the notice or claim of lien in the required public records offices within a specified period of time after the materials have been supplied or the work completed (all states). The law varies from state-to-state on both the triggering event and the timing of this. Some states require the filing within a period m... |
*Filing a lawsuit to foreclose the lien within a specified time period. |
Priority respecting other interests |
The statutes creating mechanic's liens usually give them a higher priority with respect to other interests in the title than the law gives most real property security interests. Among other things, priority is the attribute that determines which of several competing security claims will have the first claim to the fund... |
Special provisions are made in some states for determining the priority between a mechanic's lien and the lien of a mortgage that is financing the construction on the land. For instance, in the State of New York, the appearance of specified language in the mortgage to the effect that it is a construction loan preserves... |
Mechanic's liens are enforced exclusively through judicial foreclosure sales, i.e., through court proceedings similar to mortgage foreclosures. The court must determine whether the requirements of the statute have been met and, if so, the priority of the mechanic's lien being foreclosed relative to the other liens or e... |

What's the point of grad committee meetings? |
Jun 29 2012 Published by under [Education&Careers] |
I don't even know how many committee meetings I have been to, either as a student or supervisor. Every place does them slightly differently and there is usually substantial freedom in the format and tone. Some include a formal presentation, written report before hand, or both. Others are a casual conversation. |
As fas as I know, however, the point of having a committee meeting is mainly to get some constructive "outside" guidance on the work you are doing and have planned. Lot's of other things can come out of committee meetings, but making sure you don't have your head stuck up your advisor's ass is a key component. In most ... |
Based on this, I was surprised to read Algae Girl's post about her first committee meeting happening at the end of her third year. In a follow-up post she mentions she may be defending in December, indicating that her first committee meeting is happening at the 11th hour of her degree. Any input from the committee at t... |
I have to say that I'm a little surprised a degree program would be set up that way, although it could just be how things fell for her. In my department, the committee needs to be established and a research proposal needs to be submitted to the grad school, no later than the end of year one. The committee has to sign o... |
What do you see as the point of committee meetings, at least as they are intended (I've been to some useless ones)? How early and often are the done at your institution? |

Our masters' students are supposed to have a committee meeting in their first semester, and annually after that. The goal is to make sure the student is making good progress. We'd had a bad patch where some students were just adrift, so the annual meeting is a way to make sure the wheels are still turning and not s... |
• Bashir says: |
It could also be that the program isn't set up in a particular way. At my grad institution the only actual required meeting was the final defense (maybe prelim too). By required I mean a written down university/departmental rule that you could not get out of. Everything else was convention. Most people had frequent... |
Basically the point of grad committee meetings was whatever you wanted to be. |
• proflikesubstance says: |
I would argue strongly that it is poor institutional policy to leave this up to the students. |
• studyzone says: |
In my PhD program, the committee served two purposes: 1) to provide outside perspectives on the student's project (which I found very helpful), and 2) to serve as a safety net to protect against rogue/unreasonable PIs. There was a codified set of rules that committees and students had to satisfy (annual meetings, s... |
• anon says: |
No, she says she's doing a 'oral/proposal defense', i.e., advance to candidacy exam in December, not a final thesis defense. |
• proflikesubstance says: |
Ah, I see that now. Nevertheless, three years is a long time. |
• anon says: |
We're required to have annual committee meetings, where this first meeting must be within one year of passing the qualifying exam. Each meeting requires a write-up and a presentation. I'm sure the reasons for these meetings are the usual ones (outside perspective, protection from unreasonable advisors, make sure st... |
• Daimia says: |
I'm having my first 'introductory meeting' in a couple of weeks. In the past the first meeting used to be the actual exam which sounds pretty intimidating if it is the first time you come face to face with the members. Now it's different. I (we) get an introductory meeting to get them all in the room and give a sho... |
• Daimia says: |
Committee needs to be in place before the end of the second year (I'm nearing the end of mine) and proposal defense needs to happen before the end of 3rd. The proposal committee remains the same throughout the program and administers the final defense. I know that there are other programs which have different commi... |
• Dr. O says: |
For all of the programs I've been involved in, the first committee meeting is during year 3. The first year the students are rotating. The second year, they're taking a few more classes and preparing for qualifying exams - format for these varies extensively, but generally does not involve their own research. Begin... |
The point of the committee meetings, from my standpoint, is generally what you suggest - to provide an outside perspective of the candidate's project, data, and progress. Given the timeline above, this gives 3-4 years of interaction with the committee, assuming a 5-6 year PhD stint. I prefer formal committee meetin... |
• icee says: |
The schools I've attended all have the requirement of 1st meeting in the 1st year, and annual meeting/forms filed in each subsequent year. Neither of the schools I have been to enforced that rule, until last year. Because the rule wasn't enforced, lots of students delayed meetings or even appointing a committee for... |
I've always had meetings when I was supposed to because they almost always benefit the student - all my meetings have been extremely helpful. New department chair started cracking the whip a year ago on enforcement and there was LOTS of grumbling. The results have been good, though. You may think it's better for yo... |
I never understood the logic of students trying to get out of committee meetings. If your committee sucks that bad, change it (if you can). If you suck that bad, change you! |
• Jim Thomerson says: |
One of my undergraduate students went into a PhD program in biology at a respectable university. At his first committee meeting, his committee asked him what he wanted to do professionally. He said he wanted to teach. They gave him a really hard time. He dropped out of the program, and got a MS in Junior College Ad... |
• lylebot says: |
In my field there are usually just two committee meetings: one for the proposal and one for the defense. And it's not rare that they happen with less than 12 months in between. |
I was on one committee that included a biologist (the student was doing some work related to biology) and that followed that template. The biologist was not too happy about the whole thing, even though she had a major role in the work and had frequent meetings with the student and her advisor. |
• Hermitage says: |
Yup, my dept is similar to lyle's. My committee members are big cheeses, so even trying to pin them down for extraneous meetings would be a feat in and of itself. I guess I'll find out who good/bad that is when I go in for meeting #1, lol. |

• ponderingfool says: |
My PhD granting department had a qualifying committee at the start of your second year. Assuming you passed quals, you met your thesis committee (advisor plus at least two other faculty members of your choice & their consent) at the end of your second year. Year three & four met once a year in the spring. Years 5 a... |
The committee was to help, keep students on track, protect students from absurd/abusive advisors (well the other two members), force students to think about the big picture, and serve as mentors. |

Dude, 5-6 years is pushing it. This may be field-specific, but I try and get mine through in a lot less time than that. But we don't seem to have the same early time-line so the students here can dig in quite a bit sooner. |
• newly minted PhD says: |
I recently defended my PhD in a physical sciences department that encouraged interdisciplinary work, so that my advisor was in a biological sciences department. In my home department, only one committee meeting is required, and that meeting takes place during the student's 4th year. (6 years is approximately the "n... |
