はてなキーワード: rawとは
I've noticed a non-negligible number of people who have not only completed compulsory education in regular classes but have also received higher education and graduated from university, yet struggle with reading comprehension (understanding the meaning of text), cannot read long texts, and even have difficulty understanding videos.
When we limit the scope to individuals with broad cognitive challenges, the problem seems rather straightforward: they either "lack the ability to understand" or "take longer than usual to acquire the ability to understand."
Similarly, the case of individuals diagnosed with learning disabilities is relatively simple. While they may not have broad cognitive challenges, they require different approaches and training due to their unique learning styles.
However, it is perplexing that university graduates without broad cognitive challenges or diagnosed learning disabilities struggle to understand not only written text but also simplified video content.
I suspect that the underlying causes might include gaps in the horizontal transfer of experiences and knowledge, a severe lack of adaptability, and an extreme deficit in metacognition. Has there been any research on these issues? Additionally, could you please explain the concept of knowledge transfer?
(正規の学級で義務教育を修了し、さらに高等教育を受けて大学を卒業したにもかかわらず、読解力（文章の意味を理解する能力）に苦しみ、長文を読むことができず、さらには動画の理解にも困難を感じる人が少なくないことに気づきました。
認知能力に広範な課題を抱える個人に範囲を限定すると、問題は比較的単純です。「理解する能力がない」か、「理解する能力を獲得するのに通常よりも時間がかかる」かのいずれかです。
同様に、学習障害と診断された個人の場合も比較的単純です。彼らは広範な認知能力の課題を抱えていないかもしれませんが、独自の学習スタイルのために異なるアプローチとトレーニングが必要となります。
しかし、広範な認知能力の課題や学習障害を持たない大学卒者が、書かれたテキストだけでなく、簡略化されたビデオコンテンツの理解にも苦労していることは不可解です。
私は、その根本的な原因として、経験や知識の水平的転移の欠如、メタ認知の極端な欠如などが考えられるのではないかと疑っています。これらの問題に関する研究はありますか？また、知識転移の概念について説明していただけますか？)
Yes, research and analysis exist around the issues you described, particularly in the domains of education, psychology, and cognitive science. Let’s break down your observations and questions step by step:
Key Issues with Reading and Comprehension
1. Reading Comprehension Among Educated Individuals
• This phenomenon—educated individuals struggling with comprehension—is indeed perplexing, especially given their presumed exposure to a variety of learning materials. It suggests that education systems sometimes emphasize rote learning and surface-level knowledge acquisition over deeper understanding, critical thinking, and metacognition.
• Horizontal Transfer Gaps: This refers to the inability to apply knowledge or skills learned in one context to another. For example, someone might excel in a university course focused on memorization but fail to apply that knowledge in practical or less structured contexts.
• Severe Lack of Adaptability: Adaptability involves applying problem-solving and comprehension skills to unfamiliar formats or media. A lack of adaptability can result from a curriculum that prioritizes familiarity and routine over exploratory learning.
• Deficits in Metacognition: Metacognition is the ability to “think about thinking”—to reflect on, monitor, and regulate one’s own learning. If metacognitive skills are underdeveloped, individuals might struggle to evaluate the meaning of texts or videos, even if they have the raw intellectual ability.
Research Insights
1. Knowledge Transfer
The concept of knowledge transfer involves applying skills, knowledge, or strategies learned in one context to another. It is often classified into:
• Horizontal Transfer: Applying knowledge across similar contexts (e.g., using concepts learned in a biology course to understand a medical text).
• Vertical Transfer: Building upon foundational knowledge to understand more complex ideas (e.g., using basic algebra to solve advanced calculus problems).
Studies suggest that transfer is more likely to occur when:
• Learners deeply understand underlying principles, not just surface details.
• Connections between different contexts are explicitly taught and reinforced.
• Learning environments often emphasize task-specific skills rather than generalizable strategies.
• Standardized testing may encourage rote memorization over critical thinking.
• Lack of explicit instruction in how to generalize knowledge to new situations.
Research highlights the importance of metacognition in learning. Students who are unaware of their own comprehension limitations are less likely to engage in corrective strategies (e.g., rereading, seeking clarification). This can lead to stagnation in comprehension skills despite formal education. Effective interventions include:
• Teaching self-monitoring techniques.
• Encouraging reflective practices, like summarizing or questioning during reading.
4. Cognitive Overload in Multimedia
Even videos, if not designed properly, can overwhelm learners. The Cognitive Theory of Multimedia Learning suggests that excessive extraneous information or unclear organization in videos can overload working memory, hindering comprehension.
Strategies and Research-Based Solutions
1. Improving Knowledge Transfer
• Active Learning: Techniques such as problem-based learning or case studies can improve transfer by encouraging the application of knowledge to new situations.
• Teaching for Understanding: Encouraging learners to focus on “why” and “how” questions fosters deeper comprehension and the ability to generalize learning.
• Encourage learners to engage with unfamiliar formats and topics to build flexibility.
• Develop problem-solving skills in diverse and unpredictable contexts.
3. Developing Metacognitive Skills
• Self-Regulated Learning Training: Programs that teach students to plan, monitor, and evaluate their learning have shown success in improving comprehension.
• Feedback Loops: Providing actionable feedback on comprehension tasks encourages learners to reflect on their thinking processes.
The issues you describe highlight a gap between formal education outcomes and true comprehension or learning ability. Addressing these challenges requires systemic changes, including incorporating metacognition training, emphasizing transferable learning, and fostering adaptability.
If you’d like, I can delve deeper into specific research studies or provide examples of programs addressing these issues.
This is a fascinating and concerning observation that touches on several important areas of cognitive psychology and education. Let me address this systematically.
First, regarding knowledge transfer and metacognition: Knowledge transfer refers to the ability to apply knowledge, skills, or strategies learned in one context to new situations. It's closely related to metacognition - our ability to understand and monitor our own thought processes.
Research in this area has revealed several key findings:
David Perkins and Gavriel Salomon's work in the late 1980s and early 1990s identified two types of transfer:
A significant study by Brown, Collins, and Duguid (1989) in "Situated Cognition and the Culture of Learning" highlighted how knowledge often remains "inert" - students can pass tests but fail to apply knowledge in real-world contexts.
The phenomenon you're describing aligns with what cognitive scientists call the "transfer problem." Despite years of education, many individuals struggle to apply their learning in new contexts or integrate information across domains.
Some relevant research directions:
1. Cognitive Load Theory (Sweller et al.)
Shows how working memory limitations affect learning and transfer. Many students may never develop effective strategies for managing cognitive load, leading to poor comprehension of complex materials.
2. Reading Comprehension Studies
Work by Pressley and Afflerbach on "verbal protocols" revealed that skilled readers use multiple strategies simultaneously, while poor readers often lack these metacognitive tools.
3. Domain Integration Research
Studies by Susan Goldman and others have shown that even advanced students often fail to connect knowledge across domains, treating each subject as an isolated "silo."
Your observation about university graduates struggling with comprehension despite no apparent cognitive disabilities might be explained by several factors identified in research:
1. Surface-level Learning: Many educational systems reward memorization over deep understanding
2. Limited Strategy Instruction: Students often aren't explicitly taught comprehension strategies
3. Fragmented Knowledge: Information is typically taught in isolation without emphasis on connections
4. Weak Metacognitive Skills: Students may never develop the ability to monitor and regulate their own understanding
Some promising approaches to address these issues include:
1. Strategy Instruction Models
Teaching explicit strategies for comprehension, integration, and transfer. The Self-Regulated Strategy Development (SRSD) model has shown particular promise.
2. Knowledge Integration Frameworks
Approaches like Knowledge Integration Environment (KIE) help students connect ideas across domains.
3. Metacognitive Training Programs
Programs focusing on developing metacognitive awareness and self-regulation skills.
Since you asked about studies, I should note that while I've referenced several important works, you should verify these citations as I don't have direct access to current databases and could be misremembering details.
Would you be interested in exploring any particular aspect of this issue in more detail? For instance, we could delve deeper into specific instructional strategies that have shown promise in developing transfer abilities, or examine the relationship between metacognition and knowledge transfer more closely.

まずな？プロはマニュアルしか使わないなんて嘘だ。特に動体撮影する連中は逆にオートフォーカスしか使わん。スポーツ写真でもアイドルのライブ写真でもオートフォーカスが基本。
そしてSONYの正直に言ってマニュアルフォーカスは使いにくく、マニュアルフォーカスの扱いやすさで言えばキヤノンが優勢だ。なぜかって？家電量販店で試してこい。マニュアルフォーカス時のユーザーインターフェースの時点で出来が違うから。
SONYはなオートフォーカスがすべてだ。キヤノン党やニコン党やフジ党に聞いてみろ。口を揃えて「SONYのオートフォーカス"だけ"は敵わないっすねぇ」って言うから。
SONYがはじめてカメラでSONYのオートフォーカスが当たり前になってみろ。他社へ乗り換えた際に「遅っ！！」「えっなんで認識しねぇの！？」となるのは確実だ。
動画撮影機能も家電メーカーだけあって優れており、その辺りのバランスの良さからSONYカメラは子供が生まれた新米パパに人気になっている。購入年齢層が本当にそれなのである。若者やYoutubeで人気なのはこういう万能的なカメラだし実際に売れてる。
白飛びしやすいというのは些か語弊があり、露出オーバー気味・・・つまりは明るく写そうとする傾向があるのだ。だから明暗差の大きい例えば室内の窓から屋外の景色を写そうとすると盛大に白飛びする。
しかしこれは他社でも明暗差の大きいシチュエーションでは同じでキヤノンはその傾向が強めに出ると思えば良い。何でもかんでも白飛びするわけでないので大げさに心配する必要はない。
キヤノンと言えば人肌と言われるほど人物撮影が得意と言われている。この評価は確かにそうだが実際には発色が良いと表現したほうが適切だ。
キヤノンは現実世界の色味をそのまま出すのではなく人間が綺麗だと感じたり、過去の思い出の中で振り返る美しい景色などの色味、いわゆる「記憶色」で写すメーカーなのだ。
だからこそ雑誌やインターネットで見たような色味の写真を撮りたいみたいな需要にマッチする。iPhone的と言えばiPhone的だが、むしろ逆でiPhoneがキヤノンのパリッとした発色をソフト処理で真似てる。コンピュテーショナル・フォトグラフィーってやつだな。
あとファインダーを覗くと視線でオートフォーカス対象を決定できる機能がメチャクチャ凄いので、家電量販店でマニュアルフォーカス試すついでにやってみると良い。むしろコッチのほうが感動する人は多いハズ。
ニコンは純正レンズだ！ニッコールだ！レンズ性能が他社よりも1歩2歩進んでいて、その光学性能はカメラメーカーというかレンズメーカーの中でも随一だと言って良いだろう。双眼鏡も単眼鏡も望遠鏡もニッコール！
オートフォーカスが弱い？いやそれは化物オートフォーカスのSONYと視線オートフォーカスのキヤノンと比べるのが悪いのであって、こういうこと言う輩はRICHO GRシリーズとか使ったこと無い輩なので聞く耳持たなくて良い！下には下が居るぞ！RICHO GRシリーズユーザーでGRのオートフォーカス信用してるヤツに俺は会ったことがないからな！(笑)
ニコンの色味は現実に合ったナチュラルカラーの「自然色」だ。とは言っても大半のカメラマンはRAW現像してしまうので一発で決まった色味の出るキヤノンと比較するならばRAW現像前とRAW現像後の比較がしやすいのがニコンだな！キヤノンは撮った時点のものがもうコレで良いんじゃね？となりがちだ！
RAWファイルをギリギリまで追い込んで遊びたい！みたいなヤツはニコンの方が楽しいかもな。面倒臭いから一発で良い感じの出せって言うならキヤノンの方が良く、子供やペットを追いかけ回して写真も動画も何でもやりたい！ならSONYだ。
あぁちなみにだが写真機としてのボディ形状やボタン配置などは好みの差はあるもののSONYよりもキヤノンやニコンの方が優れていると言うカメラマンは多いし実際に俺もそうだと思う。
もうハッキリ言おう！こいつは動画機だ！写真機としてはまだまだ未完成だ！いやぁ惜しいんだけどな！キヤノンやニコン、SONY、富士フイルムの完成度と比較しちゃうとなぁ……。
しかし動画機と見ればかなり良い。手ブレ補正は効きまくりだしYoutube全盛のインターネットで相当にマッチしていると言って良い。動画がメインで写真はオマケっていうヤツが買え！
でも昨今の機種に搭載が始まっているユーザーが色味を自由自在に出来てしまうリアルタイムLUTは非常に楽しい機能なので、リアルタイムLUTのためだけにパナにするってのもナシではない。
中判というどデカいイメージセンサーを搭載しているカメラを販売しているが主力は中判よりも小さいフルサイズよりも小さいAPS-Cイメージセンサーを搭載したカメラだ。
APS-Cよりも小さなマイクロフォーサーズ搭載カメラにも言えることだが、カメラもレンズも小型軽量なのは正義ですよ。持ち歩く気になるか？ってのはカメラ趣味にとって大きな要素なのです。
だからこそ言いたい女性諸君！キミたちのカメラはコレですよ！中判とかフルサイズとかデカくて重いしさ、結局のところ男が使うことを想定してるんだもの女性の手や体格じゃ中判やフルサイズはキツイって！
ジジイもさ女性モデルさんにカメラ持たせて雑誌レビューしたことあるが、中判やフルサイズなんてモデルさんの顔面と同じくらいのサイズあるんだよ？ポーズ取って貰うんだけど重くてツラそうなの！実際に重いんだってさ！
そこでAPS-Cに本気な富士フイルムですよ！ついでにマイクロフォーサーズを本気でやってるPanasonicですよ！これのレビューのときはねモデルさんも楽なんだよ！フルサイズのカメラレンズなんて女の子の拳よりもデカいんだからね？APS-Cはそんなことない！
APS-Cサイズ感がちょうど良くて、更にフィルムメーカー富士フイルムがこだわる色味で撮影できるわけですよ。オートフォーカスの効きもそこそこ良いし動画だって撮影できる。ボディ筐体のデザインもレトロでおしゃれだ。コスプレイベントでも富士フイルムの女の子カメラマン見たこと結構あるぞ！
ちなみにだがジジイのカメラはキヤノン EOS R3、SONY α7CR、ニコン Zf、富士フイルム X-T5、RICOH GR3x、Leica M11です。R3はしっかりした仕事以外で使いたくねーから普段はそれ以外の気分で持ち歩いてる。

https://www.sony.jp/ichigan/products/ILCE-1/photo-sample.html
発売したばかりとか発売前のカメラの場合は無い場合もあるが、基本的には後日追加される
ところがLUMIXのページにはそれがない
今回のS9だけではなく古いカメラに遡っても無いので、そもそも撮影サンプルを集めるという業務フローが存在しないのではないか
他社のように撮影サンプルを集めるようなフローがあればその中からWebサイト用の画像を準備すれば良くて
ただ、S9の商品ページが更新されて画像に使用機材が追記されたのだが
例えばLUMIX S5IIXを使用、と書いてあるくせにLUMIX S5IIXのページに撮影サンプルはない
というかそもそもLUMIX S5IIXのページはただの仕様を載せただけで製品紹介ページがない
全くもってPanasonicのやっていることが謎すぎる
VBA嫌いのExcel師(営業事務)なんだけど、その程度のことをVBAでやろうとするヤツを駆逐したい。
お前は営業や他のユーザーの理解度を自分レベルだと勘違いするのをやめるべき。
うちの会社はVLOOKUP(最近はINDEXとMATCH)組めるのが「Excelできる」と名乗っていい最低限のラインで、営業と営業事務では名乗れないやつはほとんどいない。でもVBAは使える人は稀。
基本はその「難しくてもVLOOKUPの知識を駆使すればなんとかなるレベル」でExcelを組まないと破綻する。
うちの会社の一事業部は複数の会社に発注をしていて、そうすると会社ごとにデータを比較して見たいのに項目や項目順が違って簡単に比較できない、ということがよくある。
その場合マッピングと呼ばれるデータ項目の統一化が必要なんだけど、会社によって合算したいデータがそれぞれ別の方法でしか取れないとか、合算値に余計なデータが入ってるからrawデータ取ってきて件数はレコード数でカウントしないといけないとか、まぁ色々出てくる。
全取引に対してのデフォルト対応としての統一マッピングはしてるけど、そういうのはVBAでやらずにSaaS使ってるし、ものによって重視する値が変わるので例外が2割くらいある。うちの会社はその辺りの裁量が営業に認められているので例外も多め(なおオンリーワンになりたいためだけに特殊対応した奴は一人を除いて矯正or自滅済)
そういう融通をきかせるのにExcelの計算シートでマッピングするのは絶対。
あとVBAだと営業側が「どういう計算をしてるのか」とか「正しい数値が出てるのか」が確認できない。
っていうのは例えば100円3件と150円2件の仕入れにうちの取り分2割乗せて720円として見せたかったのに、『=100*3+150*2*1.2』って数式書いたせいで660円になっとるやんみたいな。こんなんよくある眠い時のヒューマンエラーで、VBA書く人ならやらかさない、なんてことは絶対ない。
しかも営業がこういうのの修正とか提案用にちょいちょいと列増やして数式入れようとしても「マクロ壊れるからやめて」とか言われる。営業が自分で調整可能なら1時間以内でできるものでも、VBA書いた人に依頼しなきゃいけないんだと、書いた人の通常業務との兼ね合いで1週間待たされたりする。
営業に金稼がせるためには営業の利便性と裁量は必須で、Excel利用者に裁量権が認められてないVBAのツールなんか全体最適化されてないクソ。
※なお裁量大きいからってあんまり好き勝手するとやらかした時に他の助けも得られず(やれることに限界がある)自滅ルート
自分も軽くVBA習得してるんだけど、フォルダ内のデータ一括読み込みとシートの分割統合の関数代わりにしか使ってない。しかもただの効率化なのでVBAが死んだところで手作業に戻せる範囲。
他人が保守できるように作るのならVBAなんか入れるべきではないし、VBA入れないなら計算シートは必須。あと計算周りを大掛かりにやるならSaaS入れてDX検討すべき。
2023年も残りわずか、GooglePhotosでも見て振り返ってみる
概ね良し、転職してよかった。(個人的に)映画が豊作だった気がする、異端の純愛、Winny、シン仮面、マイナスワン、ザクリエイター。
ミュージシャンの訃報が多かった。特に櫻井敦司が亡くなったことはボディブロウ
インフラエンジニアからSREもどきになろうとしてる。稼働時間は変わらず給与は爆上がりしたけど業務内容のハードルは青天井、バケモンみたいな他社員と自分を比べると死ぬ。
前職の後半くらいに社会人力が落ちたこともあるのでそこをどうにかしたい
身内練習イベントから普通にお客さんが来てくれるイベントまで急成長。そこそこのビッグネームをゲストで呼ぶことができた。

自宅に4chのコントローラー(DDJ-FLX6)を導入したことで3Deckでまともにセットを組んだりプレイできるようになったと思う

選曲、セット組み、ブッキング、フライヤー作成でキャパ的にも限界超えてるのでさらに負担減らせるようにして
このまま継続していきたい。トンネルトーキョーでDJやってみたいけど思想が近そうなVJさんとコネクションが無いので作りたい
デジタルのみだったけど祖母や祖父の遺品のフィルムカメラを使い始めた。
普段RAW現像をしないこともあって勝手にいい感じになってくれて良い

写真始めて2年たった？くらいだけど自分の嗜好としては一般的なポートレートには飽きていてテンションが上っていないので
来年はセンシティブな写真をもっと撮りたい。その手のヌードモデルの人とコネクションが無いのでアダルト撮影会とかから始めたい。
そもそもモテる人間では無いのに、仕事と趣味に全て振ってしまったため、自分の身なりをまともにすることや、出会う努力ができず、何もなかった。
どうにかしたいがたぶん趣味を減らさない限り無理だろう。年末は甥っ子に会ってくるので子供欲しい欲はさらに上がるはず？
食生活改善(≠ダイエット)、朝散歩、貯金継続、ペーパー10年目になりそうなので運転練習
そんなところ。後でセルクマ
Appleが「Macの8GBはWindowsの16GB相当だぞ」と言ったもんだから、世間が騒がしくなっている。
それに輪をかけて、「Macの8GBと16GBを比べたら、16GBの方が速いぞ」という、いっけん関係していそうで、よく考えればまったく関係のない比較が結びつけられてしまって、これが人々の混乱を招き、騒ぎを大きくしてしまっている。
- M3 MacBook Proの8GBのメモリはWindows PCの16GBと同等 - こぼねみ
- Apple幹部、MacBook Pro (14-inch, M3, Nov 2023)の8GBメモリは他のノートパソコンのメモリ16GBに相当するとコメント | Mac | Mac OTAKARA
- M3 MacBook Proのメモリ8GBは「Windows PCの16GBに相当する」 | ゴリミー
- 「メモリ8GBは不十分」ーーM3 MacBook Proの検証動画が公開 | ゴリミー
- Appleが「M3 MacBook Pro」の8GBのユニファイドメモリは16GBの他製品RAMと同等であると主張 - GIGAZINE
いずれはまともな検証動画が上がってくるとは思うが、ひとまず、2023年以降のMax Techチャンネルに上がっている、Windowsとのメモリ効率の比較が可能な動画をあさり、並べてみたのでご覧いただきたい。私自身も懐疑的だったが、こうしてみると、あながちAppleの主張も荒唐無稽だとは言えないようだ。

注:
もっとも、先述の通り「Mac同士で8GBと16GBを比べたら当然16GBの方が余力があるので、Proを名乗る機種は16GB備えるべきだ」という意見は至極真っ当だとも思う。すなわち、上記のようなベンチマーク環境から、たとえばChromeのタブを追加で開いていったらどうなるかというと、MacだろうがWindowsだろうが8GB機ならすぐに悪影響が出てきてしまう。Macの8GBメモリの「処理効率」は確かに16GB相当かもしれないが、「同時に扱えるデータ量」は別物だということに注意してもらいたい。Macは後者についても効率的なのかもしれないが、それをWindowsとの比較で検証できる動画は見つけられなかった。
追記:
赤字で示したM3シリーズのうち、M3の2機種を比べてみてほしい。この2機種の違いは8GBと16GBの差、$200だけだ。それで1:47から1:03まで改善するのだから、$200の価値は高いと思う。またこの数字は、同時にChromeのタブを開いていく検証(参照元3)では、ますます差が開くことになる。16GBのほうは、20タブを開いてもびくともしない。

なお、これはまさに冒頭で触れた「Macの8GBと16GBを比べたら、16GBの方が速いぞ」という検証である。Windowsとの比較を終えて、結局行き着くところはここなのだった。
