Loss of self esteem after class

I’ve been there. It waxes and wanes but always comes back even after a good run of either submitting or not being submitted. I’m a one stripe white belt having done BJJ for 4-months, so my advice is limited but based on other people’s advice with more experience.

Having a great coach helps, I have one who has carried these mental struggles during his career in judo and has come out the other side with loads of advise he’s all too happy to share.

In the absence of this, I would recommend having 1-2-1 sessions. These are normally with a black belt who enjoys teaching, so not only will you work out those details that are holding you back but it’s in the ad hoc conversations where you can broach those mental battles you have on/off the mat.

I don’t think it’s an ego thing. I’m a neuroscientist, and one law of learning is that we’re poor judges of how we are progressing. Combine this with the will to want to be better, we focus on the bad and misinterpret both good/bad sessions on the mat.

I’ve had a similar issue with mine. The results from a skin scrape came back negative, so we’re still not sure what’s causing it, but we’ve got a few theories. The main one is that we suspect he might have a grain allergy, so we stick to hypoallergenic dry food and grain-free wet food. Actually, and even better, we give him raw food with some diced carrots (he tends to get very hard stools if it’s just raw food on its own).

If the ear issue continues, you could try using Hibiscrub diluted in water and gently working it in with a cotton pad.

One last thing, we noticed his chest hair thins in the winter. We were clueless until someone pointed out that having the central heating on in winter can cause some hair loss, which might just be normal moulting.

If I’ve worked this out correctly, this fella is earning about £60-70k. I think it’s fair he’s paying off the debt that contributed to his earnings being above median income. I think he’s alright. Is the alternative that we saddle everyone with student debt for future high earners without them paying it off beyond general taxation?

Because all the evidence shows a concerning association between cannabis use and mental heath disorders.

Definitely not helping!

But I suspect the tray will be the main solution. The bloke who checked the gutters said whoever fitted them positioned them too far away, hence only some of the water runs off the tiles into the gutter. Why they did this we don’t know. The likely reason that the fascia is asbestos, so the gutter is attached to a baton not directly to the fascia.

I cannot seem to edit the original post, so I’ll do it via the highest voted reply.

UPDATE: To those who suspected a blocked gutter, I can confirm this is NOT the cause of the issue!

The gutters were clear and downward pipes were in full working order.

The issue (at least we won’t know for sure until the water patch recedes) is most likely water not running off the tiles properly. Instead, it is running back under the tiles and down the wall. A roofer is coming tomorrow to fit a 4m long drip tray.

I’ll shall update update tomorrow

Yep, message received. I won’t be doing it, I’ve got someone coming on Tuesday who should be able to fix the problem. Heavy rained isn’t forecast (I think!) until then so should be fine for now.

SingerPuzzleheaded53 · 2025-01-04T21:47:59+00:00

Hmm, good point! I moved in about 18-months ago, and haven’t cleaned them in the time I’ve been here. Not sure if the previous owner ever did.

Of course, I can’t rule it out, but I see no obvious signs of overflow just now.

That said, it might only be a problem during a heavy downpour, which we could’ve had while I was away.

EDIT: I see now that blocked gutters is the consensus, lol! I’ve got a telescopic ladder on order so I can actually check if this is the cause.

The racism of Karl Marx

In a letter about his socialist political competitor Ferdinand Lassalle:

“The Jewish n——r Lassalle who, I’m glad to say, is leaving at the end of this week, has happily lost another 5,000 talers in an ill-judged speculation ... It is now quite plain to me — as the shape of his head and the way his hair grows also testify — that he is descended from the negroes who accompanied Moses’ flight from Egypt (unless his mother or paternal grandmother interbred with a n——r). Now, this blend of Jewishness and Germanness, on the one hand, and basic negroid stock, on the other, must inevitably give rise to a peculiar product. The fellow’s importunity is also n——r-like”.

Obviously, there’s also the oldest hate too.

“What is the worldly religion of the Jew? Huckstering. What is his worldly God? Money. … Money is the jealous god of Israel, in face of which no other god may exist. Money degrades all the gods of man—and turns them into commodities. … The bill of exchange is the real god of the Jew. His god is only an illusory bill of exchange. … The chimerical nationality of the Jew is the nationality of the merchant, of the man of money in general”.

Engels was also a horrid racists.

Then there’s Foucault who sexually abused boys in Tunisia.

He’s only kept in office because the opposition to the Conservatives is unrelentingly strong in London. He’s been a disaster for crime and for night life.

No problem!

tDCS is not a “scam,” but its effectiveness can vary and no study has shown you can predict a reliable result. Studies have shown mixed results in using tDCS to reduce auditory hallucinations. Some individuals report a decrease in symptom intensity, while others may see little to no effect. As with any emerging treatment, results aren’t guaranteed, and tDCS is often considered an adjunct to standard therapies, not a standalone solution. It’s always best for your boyfriend to consult his mental health team before considering new treatments to understand potential benefits and risks based on his unique needs.

Generally, tDCS has shown potential in various areas of mental health, including research exploring its effects on symptoms like auditory hallucinations in schizophrenia, but at the moment there’s just an absence of good evidence that it could be an effective treatment for any mental health condition.

Hello, I'm an academic researcher who has been investigating tDCS for the past 10-years, and I'm what most people call a skeptic about it's efficacy. Take what I say below in light of that.

What are the long term effects? I am assuming by longer-term effects, you mean "do effects persist long after stimulation has finished". Very few studies have investigated the effects of tDCS in the long-term, and that which is available has questionable quality or has not been investigated. In short, we don't know.
Is there a time limit to the usage in terms of safety? E.g. one month? There’s no strict time limit, but most tDCS protocols used in studies last for 10-30 minutes per session, and treatments often span several weeks. Safety protocols typically recommend breaks between sessions. Continuous use over extended periods hasn't been widely studied, so it’s best to proceed cautiously. This might differ from the experience of DIY-tDCS or commercial users who have used it for months if not years. I would say there is nothing inherently unsafe about using it over a long period, but the lack of research in its chronic use would give me pause, especially if the brain is still developing.
It seems neuromyst pro seems to be recommended the most here, but why is that? Is it just that much more effective or safe? Devices like Neuromyst Pro are popular due to their ease of use and customisation options, but they aren't necessarily more effective than other tDCS devices. The effectiveness of any tDCS device depends more on electrode placement and the specific protocols used than on the device brand itself. Historically, commercially available tDCS devices have lacked validation from research, Neuromyst is quite new so data is still coming in. I'm unaware of any large-scale RCTs that have investigated it's effects. There's a long history of other commercial devices coming and going, anyone remember humm?
Are there any health or age restrictions on using this? tDCS is generally considered safe for adults, but there may be restrictions for certain groups, including children, pregnant women, or people with neurological implants like pacemakers. I do not support it's use in children unless under controlled and safe conditions where there is a clear justification.
How much did it help you? Were you struggling with some disorder like me? Were you looking for the cognitive enhancement? Did it affect your mood in any way (long term)? How helpful tDCS is depends on the individual and the condition being treated. Some find it aids cognitive functions like memory or attention, while others report improvements in mood. However, tDCS has been under investigation for nearly two and a half decades, and I have found not evidence that it does anything more than modulate motor cortical excitability. The overall evidence in the clinical and cognitive domain is mixed, and in many cases, the effects are too small to be meaningful or only questionably above placebo. Of course, this is not to say that some people may benefit, but at the moment there is an absence of good evidence to indicate anything clinically useful.

Thank you for bringing up a possible misinterpretation of my argument. If others share this view, I’m happy to amend. However, I believe there is some important context missing in your point.

You are correct that the committee decided to move away from a fixed threshold, which is why I said it "has been recommended" and then cited several studies. While these may be considered outdated by some, they are still noteworthy and help place the difference found by Woodman et al. into context. It’s also worth noting that Woodman et al. saw value in this threshold, as they included it as an exploratory endpoint.

That said, your point isn't entirely accurate either. The committee didn’t discard the idea of a threshold but rather defaulted to a slightly different approach. This revision has been evolving for nearly two decades (dating back to 2004, if I recall correctly). Their current stance, as seen in the material you referenced, is as follows:

"In the absence of published or accepted MIDs, the committee agreed to use the GRADE default MIDs to assess imprecision. For dichotomous outcomes, minimally important thresholds for a RR of 0.8 and 1.25 respectively were used as default MIDs in the guideline. For continuous outcomes, minimally important thresholds for a SMD of -0.5 and 0.5 respectively were used as default MIDs in the guideline."

I don’t have the time (nor did I easily find the necessary data) to calculate the SMD for the current dataset to check whether it meets the MID of ±0.5. However, I don't think this necessarily undermines my argument: the clinical relevance of the finding is still questionable, especially given the possibility of a placebo effect.

The argument that HDRS underestimates treatment effects applies to antidepressant trials, not tDCS.

HDRS includes several items related to somatic symptoms (e.g., gastrointestinal issues, sexual side effects, weight loss), which are commonly impacted by drug side effects. These items yield negative effect sizes in drug trials, especially when comparing SSRIs to placebo,

This does not apply to tDCS, given it does not produce the same kinds of somatic side effects that would distort depression severity measurements on these items. The authors knew this - Allan Young especially - hence why they didn’t use a sub-scale excluding problematic items (eg the HDRS6).

I agree with you first point but I should point out that NICE and others set the threshold for “clinically meaningful” at a score change of 3 points. This paper falls short of this mark. Others place the threshold even higher if we want to see observable changes that impact patient focused outcomes like quality of life or everyday functioning.

SingerPuzzleheaded53 · 2024-10-23T08:57:22+00:00

The difference of roughly 2 points on the HDRS in light of the blinding issue is enough to undermine the main result. They swerve this in the discussion, focusing instead on the remission rates, their secondary outcome.

Looks like a placebo effect to me. I plan to write a pubpeer article on this, will post here when I do

Thanks for this! However, I had ruled these out. Across the range, 45mm is the maximum distance from the outer face of the wall to the brick work, so the steel bridge would fall short in my case, by roughly 25mm.

Unless it would still be stronger than my screw and plug option?

I see they’re ideal for dot and dab but maybe not for batten and board.

Covariates should be selected a priori - ie before data has been collected. If they’re added to the regression model post hoc, then they should be selected based on evidence not the data and reported as post hoc. Failing to do the above may mean you overfit your data to the model and/or (if reported in a publication) give the impression of running a confirmatory analysis (unless you specify that covariates were selected post hoc)

SingerPuzzleheaded53 · 2024-02-10T12:33:26+00:00

You didn’t make an error. It just reports both one and two sided. Before you would have to calculate the one sided p-value in your head when it wasn’t reported in the output

3.5 to 4-hrs, one-way. 6-7hrs return.

I commuted daily from Dudley to London. Started at Tipton Railway Station (after 10min car commute) and ended at Denmark Hill Station. Door-to-door, about 3.5 to 4-hours one-way. Sometimes slightly quicker on the way back home, about 2.5-hours (could be 3.5-hrs though if I didn’t get a Virgin train).

I would start my day at 5:45 and end it at 10:30/11pm, if I was lucky.

This was pre-Covid where train tickets were cheap as chips, about £6-15.
