Chronic Procrastination is NOT a Time Management Problem!
From : http://procrastinators-anonymous.org/node/8
The blindness of the psychological community in not recognizing procrastination as an addictive disorder also infuriates me. Every book or article I've ever read about procrastination talks about getting to the "underlying reason" why you procrastinate so you can solve the problem. Knowing why you're procrastinating on a particular task can be helpful, but it's not the whole solution - not by a long shot. That's like saying an alcoholic can stop drinking if he can only discover what's really bothering him. An alcoholic drinks because he has an addictive personality and alcohol is his drug of choice. A procrastinator procrastinates because he (or she) has an addictive personality and procrastination is his or her "drug" of choice.
Addiction and compulsion are about escaping the present moment - not being present in your life, not experiencing the reality of your life. People procrastinate as a way to not be present in their lives because they have addictive personalities, and this is the particular form their addiction takes.
How can these researchers be so blind and dense?!?! They stare right at the data and somehow miss the obvious. Procrastinators are more likely to use drugs and alcohol because they have addictive personalities, and if you have an addictive personality, you are vulnerable to using anything and everything addictively. Addiction is not related to specific substances or behaviors - addicts freely switch between them. Alcoholics become compulsive eaters and/or love addicts when they get sober, heroin addicts get off heroin by becoming alcoholics, etc.
I started this Web site and this fellowship because there is nothing out there that provides what I need. I'm sick, sick, sick of the jokes and the stupid, useless explanations of psychologists. 12-step programs work for addiction, and if there was an effective fellowship for procrastination, it would work for that, too.
Although there was a fledgling fellowship in NYC for a while (Latecomers and Procrastinators Anonymous, or LA), it seems to have died away and since there was no formal organization there is no one to contact. And anyway, I didn't find it helpful because it made a common mistake that people make in trying to help procrastinators - it gave advice on time management.
Note: Procrastinators do not have a problem with time management. They have a problem with compulsive avoidance.
If you give a procrastinator a new time management tool, he will just play with the new time management tool as a way to procrastinate. The problem is not a lack of time management skills - or not mainly a lack of time management skills. Procrastination is a form of addictive escapism that must be dealt with directly or there will be no recovery.
Recovery from procrastination (aka compulsive task avoidance) cannot be achieved by abstaining from your current favorite procrastination activity, because you'll just switch to something else (just as cutting out certain foods doesn't resolve compulsive eating problems). Recovery from procrastination means doing what you say you're going to do, when you say you're going to do it.
Not a Laughing Matter!
The jokes about procrastination infuriate me. This is not a funny problem - not if you are suffering from true, chronic procrastination. Lawyers have been disbarred due to procrastination. Small business owners have lost their businesses due to procrastination. People's lives fall apart and are destroyed due to procrastination. This is not a funny problem.The blindness of the psychological community in not recognizing procrastination as an addictive disorder also infuriates me. Every book or article I've ever read about procrastination talks about getting to the "underlying reason" why you procrastinate so you can solve the problem.

Addiction and compulsion are about escaping the present moment - not being present in your life, not experiencing the reality of your life. People procrastinate as a way to not be present in their lives because they have addictive personalities, and this is the particular form their addiction takes.
Misguided Advice from "Experts"
Until very recently, there was almost no research at all on procrastination in the psychological community. Now there is some research, but mostly unhelpful personality correlates, and laundry lists of the hidden "reasons". More recently, a few researchers have noticed that procrastination is a "marker" for alcohol and drug abuse - that procrastinators are much more likely to also abuse drugs and alcohol. But the uninsightful explanation given for this correlation is that procrastinators are using drugs and alcohol to deal with the pain of their procrastination.How can these researchers be so blind and dense?!?! They stare right at the data and somehow miss the obvious. Procrastinators are more likely to use drugs and alcohol because they have addictive personalities, and if you have an addictive personality, you are vulnerable to using anything and everything addictively. Addiction is not related to specific substances or behaviors - addicts freely switch between them. Alcoholics become compulsive eaters and/or love addicts when they get sober, heroin addicts get off heroin by becoming alcoholics, etc.
Who Am I, Anyway?
I am a chronic procrastinator (with graduate training in psychology) who has also had to deal with a variety of other addictive problems. I've been clean and sober for nearly a decade, and I've resolved addictive problems with food and relationships as well. I know what addiction feels like. Procrastination feels like addiction, and it's the very hardest addiction I've ever had to deal with. It's harder to stop procrastinating than it is to quit drinking, drugging, smoking, compulsive eating, and romantically obsessing all together.I started this Web site and this fellowship because there is nothing out there that provides what I need. I'm sick, sick, sick of the jokes and the stupid, useless explanations of psychologists. 12-step programs work for addiction, and if there was an effective fellowship for procrastination, it would work for that, too.

9 Publishing Basics for Anyone Submitting to a Scholarly Journal
9 Publishing Basics for Anyone Submitting to a Scholarly Journal
From:
http://connection.sagepub.com/blog/2013/11/05/9-publishing-basics-for-anyone-submitting-to-a-scholarly-journal/
Leah
Fargotstein, a Social Science Journals Editor here at SAGE, was recently asked
to participate in a panel where she was asked some basic, yet essential
questions about getting published in a scholarly journal. In an effort to
support any graduate students and early-career scholars out there who may have
wondered about the questions below, we asked Leah to write up her responses.
Here is what she had to say:
1. What is the point of an
abstract and how should it be formatted?
Abstracts
are basically summaries of articles. They function as “teasers” so readers can
get an overview of your article before deciding to read the entire piece. In an
online world, abstracts also make your article easier to find via search
engines, since abstracts are free for everyone to read. In the space of
around 250 words, an abstract should answer three basic questions:
What
is your research question?
How
did you go about answering that question?
What
are your findings?
Some
journals require structured abstracts which delineate exactly which subjects
should be addressed in which part of the abstract. These abstracts provide a
more organized framework for the reader to ensure authors are summarizing their
articles precisely. Structured abstracts are more popular in science and
medical fields than in the social sciences, but this is beginning to change in
the social science scholarly community as well.
2. How much effort
should one put into formatting the submission according to the guidelines? Is
it a make-or-break proposition?
The
answer to this question really depends on the journal and the editor. For any
journal with high submissions and a low acceptance rate, it very well could be.
At best, an editor will send out the paper that is poorly edited for review and
the article author will have to reformat the paper if it is accepted.
Given the various endnote programs and style guides out there for academic
papers, it is always better to format the paper correctly in the first place.
3. How long does a
submission review usually take?
Standards
vary from field to field, so it might be helpful to ask your colleagues and
mentors what you should expect for typical journals in your field. To give you
a rough idea, the first review can range from 30-60 days in the science and
medical fields and 30-90 days in the humanities and social sciences, depending
on the journal, the time of year, and the discipline.
Responses
to a paper that has been revised & resubmitted are typically faster, but
not always, especially if a reviewer doesn’t respond. In fact, reviewer fatigue
has been a problem for all journals. Peer reviewers are thorough in their work,
and they are often professors who are busy working on their own research as
well. Be patient with a journal’s editor, but feel free to ask politely about
the status of your paper if you think the time taken is much longer than your
discipline’s standard. If you have a special circumstance, such as an imminent
tenure or promotion review, make sure to note this in your email. Editors might
be able to expedite the process if they know about this.
4. Please explain the
editorial decision of Reject, Revise & resubmit, or Accept with revisions.
If you use other decision markers, please describe those, too.
While
the responses vary by journal and I am not the editor of a specific journal, I
can discuss briefly the general responses that someone submitting a paper might
receive. First, there are two kinds of rejections journals typically give: the
first is a desk rejection, and the second is a rejection with review.
The former generally involves the editor and perhaps another member or members
of the editorial board or team reading the manuscript and determining that it
is not appropriate for review. These decisions are often related to the scope
of the paper, poor quality writing, poor research design, or other factors that
the editor thinks will reduce or eliminate the article’s chances of getting
through the peer review process. The editor will explain the exact reasons in
the rejection letter. A rejection with review means the editor found the
article compelling enough to send out for review, but the reviewers of the
article found the paper lacking in some way. For high-submission journals,
reviewers may have found the paper compelling, too, but the editor must make a
decision on whether they found it compelling enough to publish, given the
limited space available to journals.
A
Revise & Resubmit (R&R) response means that the reviewers and
editors found flaws or missing pieces in the paper, but think that, with some
changes, the paper could be publishable. This is not a guarantee of
publication, but it isn’t a rejection either. Almost all papers that are
eventually published start out as R&Rs, though it depends on the
selectivity of journal whether most R&Rs are eventually published. An
editor may give you an indication of your chances for an eventual acceptance in
your decision letter. The editor will also be able to give you a general
direction of change that should be made, especially when reviewers give
conflicting advice.
Accept with revision decisions are very rare on a first review. These mean that
if you make the changes indicated in the decision letter, your article will be
accepted. This is what you might expect to see after a successful R&R.
5. When an author gets
comments back on an article from reviewers, in what amount of time should the
author expect to reply to those comments for the revision?
Again,
the amount of time can vary, but certainly not the next day, or even week.
Revisions take time, and editors know this. Depending on the extent of changes
requested, revisions can take anywhere from a couple weeks for minor tweaks to
six months or more for new data collection and analysis. An editor may give you
a deadline for revisions. If you think you won’t be able to meet the deadline,
ask for an extension and explain the circumstances. The worst answer you can
get is a no, and at least you’ll know before you start putting in the effort to
make substantial changes.
6. Some people like to
email the editor of a journal before submitting an article. Do you advise that?
When would you or when would you not?
If
you have a question about the scope of the journal or other specifics of the
journal not answered on the journal’s website, then you can email the editor.
Otherwise, I would advise against it. If you want to explain your paper in any
way, submit a cover letter with it if the journal allows you to do so.
Certainly don’t send your paper onto the editor and ask if it would be appropriate
for the journal – you’re asking for the work of the peer review process without
actually submitting. At most, you could send along the abstract, but don’t
expect a detailed response. Editors are busy people, and reviewing submitted
manuscripts is their first priority. A better tactic is to email an associate
editor or editorial board member and ask them about the journal’s process. They
may be able to give you more detail and more of their time.
7. From the editorial
perspective, what makes a great journal article submission?
Again,
this will vary widely by journal, but a well-written article is always
appreciated. An article with clear and sound methods addressing the readers of
the journal, with an innovative, developed thesis stands a higher chance of
being accepted just about anywhere.
8. What should a person
submitting an article for consideration NEVER do?
I
think you can probably glean from the above, but never send your full article
to the editor outside of the submission process; never be rude to an editor;
never try to find out who is reviewing your article; never assume you know who
is reviewing your article – as I’ve heard from nearly every editor, likely, you
are wrong even if you are sure you’re right; and if your article has been
rejected, never email the editor immediately after receiving a rejection. Even
if you have questions or feel like there was a major issue in the process, take
at least a week and then reread the decision letter. If you still feel like you
should write an email, have a diplomatic colleague review it before hitting
“send.” And never, ever submit your paper to multiple journals at the same
time. Wait for a rejection from one before submitting to another.
9. Other tips/tricks
about how to make a submission stand out?
If
you have the chance to submit an early draft of your paper to a conference, do
so. Conferences are great for getting initial comments and advice from
experienced authors who know your field. If not, get comments from colleagues
at your institution. Follow all the submission guidelines. If you’ve never
written a paper before, or think you could use some help with the process, Writing Your Journal
Article in Twelve Weeks
is a good resource. If you receive a rejection with suggested changes,
take those changes into account before you submit to another journal. The
reviewer pool for many disciplines is small – the same reviewer could very well
be reviewing your article at another journal.
Most
importantly, make sure your paper is as polished as it can be before you
submit. You may be waiting weeks or even months to receive an initial
decision. Don’t spend your time thinking of all the changes you could’ve
made while you’re waiting for a decision.

Golgi apparatus
Golgi apparatus
The Golgi apparatus (/ˈɡoʊldʒiː/), also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells.[1] It was identified in 1897 by the Italian physician Camillo Golgi and named after him in 1898.[2]
Part of the cellular endomembrane system, the Golgi apparatus
packages proteins inside the cell before they are sent to their destination; it
is particularly important in the processing of proteins for secretion.
Discovery
Owing
to its large size, the Golgi apparatus was one of the first organelles to be
discovered and observed in detail. It was discovered in 1898 by Italian
physician Camillo Golgi during an investigation of the nervous
system.[2]
After first observing it under his microscope,
he termed the structure the internal reticular apparatus. Some doubted
the discovery at first, arguing that the appearance of the structure was merely
an optical illusion created by the observation technique used by Golgi. With
the development of modern microscopes in the 20th century, the discovery was
confirmed.[3]
Early references to the Golgi referred to it by various names including the
"Golgi–Holmgren apparatus", "Golgi–Holmgren ducts", and
"Golgi–Kopsch apparatus".[2]
The term "Golgi apparatus" was used in 1910 and first appeared in
scientific literature in 1913.[2]
Structure
Found within the cytoplasm of
both plant and animal cells, the Golgi is composed of stacks of membrane-bound
structures known as cisternae (singular: cisterna). An individual stack
is sometimes called a dictyosome (from Greek dictyon: net + soma:
body),[4]
especially in plant cells.[5]
A mammalian cell typically contains 40 to 100 stacks.[6]
Between four and eight cisternae are usually present in a stack; however, in
some protists
as many as sixty have been observed.[3]
Each cisterna comprises a flat, membrane enclosed disc that includes special
Golgi enzymes which modify or help to modify cargo proteins that travel through
it.[7]
The cisternae stack has four
functional regions: the cis-Golgi network, medial-Golgi, endo-Golgi, and
trans-Golgi network. Vesicles from the endoplasmic reticulum (via the vesicular-tubular clusters) fuse with
the network and subsequently progress through the stack to the trans Golgi
network, where they are packaged and sent to their destination. Each region
contains different enzymes which selectively modify the contents depending on
where they reside.[8]
The cisternae also carry structural proteins important for their maintenance as
flattened membranes which stack upon each other.[9]
Function
Cells synthesize a large number
of different macromolecules. The Golgi apparatus is integral in modifying,
sorting, and packaging these macromolecules for cell secretion[10]
(exocytosis)
or use within the cell.[11]
It primarily modifies proteins delivered from the rough endoplasmic reticulum but is also
involved in the transport of lipids around the cell, and the creation of lysosomes.[11]
In this respect it can be thought of as similar to a post office; it packages
and labels items which it then sends to different parts of the cell.
Enzymes within the cisternae are
able to modify the proteins by addition of carbohydrates (glycosylation)[12]
and phosphates (phosphorylation). In order to do so, the Golgi
imports substances such as nucleotide sugars from the cytosol. These
modifications may also form a signal
sequence which determines the final destination of the protein. For
example, the Golgi apparatus adds a mannose-6-phosphate
label to proteins destined for lysosomes.
The Golgi plays an important
role in the synthesis of proteoglycans, which are molecules present in the extracellular matrix of animals. It is also a
major site of carbohydrate synthesis.[13]
This includes the production of glycosaminoglycans
(GAGs), long unbranched polysaccharides which the Golgi then attaches to a
protein synthesised in the endoplasmic reticulum to form proteoglycans.[14]
Enzymes in the Golgi polymerize several of these GAGs via a xylose link onto
the core protein. Another task of the Golgi involves the sulfation of
certain molecules passing through its lumen via sulfotranferases that gain
their sulfur molecule from a donor called PAPS. This process occurs on the GAGs
of proteoglycans as well as on the core protein. Sulfation is generally
performed in the trans-Golgi network. The level of sulfation is very important
to the proteoglycans' signalling abilities as well as giving the proteoglycan
its overall negative charge.[13]
The phosphorylation of molecules
requires that ATP is imported into the lumen
of the Golgi[15]
and utilised by resident kinases such as casein
kinase 1 and casein kinase 2. One molecule that is
phosphorylated in the Golgi is Apolipoprotein,
which forms a molecule known as VLDL that is a constituent of blood serum.
It is thought that the phosphorylation of these molecules is important to help
aid in their sorting for secretion into the blood serum.[16]
The Golgi has a putative role in
apoptosis,
with several Bcl-2
family members localised there, as well as to the mitochondria.
A newly characterized protein, GAAP (Golgi anti-apoptotic protein), almost
exclusively resides in the Golgi and protects cells from apoptosis by an as-yet
undefined mechanism.[17]
Vesicular transport

Macromolecules; 7. Transport vesicles; 8. Golgi apparatus; 9. Cis face
of Golgi apparatus; 10. Trans face of Golgi apparatus; 11. Cisternae of
the Golgi Apparatus
The vesicles that leave the
rough endoplasmic reticulum are transported
to the cis face of the Golgi apparatus, where they fuse with the Golgi
membrane and empty their contents into the lumen.
Once inside the lumen, the molecules are modified, then sorted for transport to
their next destinations. The Golgi apparatus tends to be larger and more
numerous in cells that synthesize and secrete large amounts of substances; for
example, the plasma B cells and the antibody-secreting
cells of the immune system have prominent Golgi complexes.
Those proteins destined for
areas of the cell other than either the endoplasmic reticulum or Golgi apparatus are
moved towards the trans face, to a complex network of membranes and
associated vesicles known as the trans-Golgi network (TGN). This area of
the Golgi is the point at which proteins are sorted and shipped to their
intended destinations by their placement into one of at least three different
types of vesicles, depending upon the molecular marker they carry.
Types
|
Description
|
Example
|
Exocytotic vesicles (continuous)
|
Vesicle contains proteins destined for
extracellular release. After packaging, the vesicles bud off and immediately
move towards the plasma membrane, where they fuse and release the
contents into the extracellular space in a process known as constitutive secretion.
|
Antibody release by activated plasma
B cells
|
Secretory vesicles (regulated)
|
Vesicle contains proteins destined for
extracellular release. After packaging, the vesicles bud off and are stored
in the cell until a signal is given for their release. When the appropriate
signal is received they move towards the membrane and fuse to release their
contents. This process is known as regulated secretion.
|
Neurotransmitter
release from neurons
|
Lysosomal vesicles
|
Vesicle contains proteins and ribosomes destined
for the lysosome,
an organelle of degradation containing many acid hydrolases,
or to lysosome-like storage organelles. These proteins include both digestive
enzymes and membrane proteins. The vesicle first fuses with the late endosome,
and the contents are then transferred to the lysosome via unknown mechanisms.
|
Transport mechanism
The transport
mechanism which proteins use to progress through the Golgi apparatus is not
yet clear; however a number of hypotheses currently exist. Until recently, the
vesicular transport mechanism was favoured but now more evidence is coming to
light to support cisternal maturation. The two proposed models may actually
work in conjunction with each other, rather than being mutually exclusive. This
is sometimes referred to as the combined model.[13]
- Cisternal maturation model: the cisternae of the Golgi apparatus move by being built at the cis face and destroyed at the trans face. Vesicles from the endoplasmic reticulum fuse with each other to form a cisterna at the cis face, consequently this cisterna would appear to move through the Golgi stack when a new cisterna is formed at the cis face. This model is supported by the fact that structures larger than the transport vesicles, such as collagen rods, were observed microscopically to progress through the Golgi apparatus.[13] This was initially a popular hypothesis, but lost favour in the 1980s. Recently it has made a comeback, as laboratories at the University of Chicago and the University of Tokyo have been able to use new technology to directly observe Golgi compartments maturing.[18] Additional evidence comes from the fact that COPI vesicles move in the retrograde direction, transporting endoplasmic reticulum proteins back to where they belong by recognizing a signal peptide.[19]
- Vesicular transport model: Vesicular transport views the Golgi as a very stable organelle, divided into compartments in the cis to trans direction. Membrane bound carriers transport material between the endoplasmic reticulum and the different compartments of the Golgi.[20] Experimental evidence includes the abundance of small vesicles (known technically as shuttle vesicles) in proximity to the Golgi apparatus. To direct the vesicles, actin filaments connect packaging proteins to the membrane to ensure that they fuse with the correct compartment.[13]
Fate during mitosis
In animal cells, the Golgi
apparatus will break up and disappear following the onset of mitosis, or
cellular division. During the telophase of mitosis, the Golgi apparatus reappears. As of
December 2009 it is uncertain how this occurs.[21]
In contrast, Golgi stacks have been observed to remain intact in plant or yeast
cells throughout the cell cycle. The reason for this difference is not yet
known, but it may, in part, be a consequence of golgin proteins.
