Identidad, orígenes y derechos en Argentina
Authors: Gesteira Soledad
Published: April 2024

En la lucha por encontrar a sus nietos/as robados durante la última dictadura militar (1976-1983) y en tanto promotoras del derecho a la identidad, Abuelas de Plaza de Mayo ha resultado una fuente de inspiración para otras formas de activismo. En Argentina desde el 2000 surge un movimiento de organizaciones sociales de personas que quieren conocer sus orígenes. Estos buscadores resignifican las consignas elaboradas por Abuelas y reclaman el estado por la garantía de su derecho a la identidad.

En este texto, a partir de la investigación etnográfica que desarrollo junto a estos activistas desde 2010 y de mi vinculo como colaborada de Abuelas de Plaza de Mayo desde 2001, analizo la conformación de lo que he conceptualizado como el campo de la búsqueda de los orígenes. Una red de actores y relaciones en la que convergen distintos activistas, instituciones del estado y organizaciones de derechos humanos. Y sostengo como hipótesis que, en tanto campo, se caracteriza por luchas, alianzas y estrategias, así como por disputas, tensiones y conflictos que se producen en su interior.
RAR fits to individual galaxies
Authors: McGaugh Stacy
Published: April 2024

The radial acceleration relation connects what we see in visible mass with what we get in galaxy dynamics. This is true in a statistical sense, with remarkably little scatter. The SPARC data are consistent with a single, universal force law in galaxies. One that appears to be sourced by the baryons alone. This was not expected with dark matter. Indeed, it would be hard to imagine a less natural result.
Degenerating problemshift: a wedged paradigm in great tightness
Authors: McGaugh Stacy
Published: April 2024

Reading Merritt’s paper on the philosophy of cosmology, I was struck by a particular quote from Lakatos:  A research programme is said to be progressing as long as its theoretical growth anticipates its empirical growth, that is as long as it keeps predicting novel facts with some success (“progressive problemshift”); it is stagnating if its theoretical growth lags behind its empirical growth, that is as long as it gives only post-hoc 
A script for every observational test
Authors: McGaugh Stacy
Published: April 2024

Science progresses through hypothesis testing. The primary mechanism for distinguishing between hypotheses is predictive power. The hypothesis that can predict new phenomena is “better.” This is especially true for surprising, a priori predictions: it matters more when the new phenomena was not expected in the context of an existing paradigm. I’ve seen this happen many times now. MOND has had many predictive successes.
A few of Zwicky’s rants
Authors: McGaugh Stacy
Published: April 2024

An important issue in science is what’s right and what’s wrong. Another is who gets credit for what. The former issue is scientific while the second is social. It matters little to the progress of science who discovers what. It matters a lot to the people who do it. We like to get credit where due. Nowadays, Fritz Zwicky is often credited with the discovery of dark matter for his work on clusters of galaxies in the 1930s.
Recent Developments Concerning the Gravitational Potential of the Milky Way. III. A Closer Look at the RAR Model
Authors: McGaugh Stacy
Published: April 2024

I am primarily an extragalactic astronomer – someone who studies galaxies outside our own. Our home Galaxy is a subject in its own right. Naturally, I became curious how the Milky Way appeared in the light of the systematic behaviors we have learned from external galaxies. I first wrote a paper about it in 2008;
Dwarf Satellite Galaxies. III. The dwarfs of Andromeda
Authors: McGaugh Stacy
Published: April 2024

Like the Milky Way, our nearest giant neighbor, Andromeda (aka M31), has several dozen dwarf satellite galaxies. A few of these were known and had measured velocity dispersions at the time of my work with Joe Wolf, as discussed previously. Also like the Milky Way, the number of known objects has grown rapidly in recent years – thanks in this case largely to the PAndAS survey.
LZ: another non-detection
Authors: McGaugh Stacy
Published: April 2024

Just as I was leaving for a week’s vacation, the dark matter search experiment LZ reported its first results. Now that I’m back, I see that I didn’t miss anything. Here is their figure of merit: LZ is a merger of two previous experiments compelled to grow still bigger in the never-ending search for dark matter.
Full speed in reverse!
Authors: McGaugh Stacy
Published: April 2024

People have been asking me about comments in a recent video by Sabine Hossenfelder. I have not watched it, but the quote I’m asked about is “the higher the uncertainty of the data, the better MOND seems to work” with the implication that this might mean that MOND is a systematic artifact of data interpretation.
Checking in on Troubles with Dark Matter
Authors: McGaugh Stacy
Published: April 2024

It is common to come across statements like “There is overwhelming astrophysical and cosmological evidence that most of the matter in our Universe is dark matter.” This is a gross oversimplification. The astronomical data that indicates the existence of acceleration discrepancies also test the ideas we come up with to explain them.
The kids are all right, but they can’t interpret a graph
Authors: McGaugh Stacy
Published: April 2024

I have not posted here in a while. This is mostly due to the fact that I have a job that is both engaging and demanding. I started this blog as a way to blow off steam, but I realized this mostly meant ranting about  those fools at the academy!  of whom there are indeed plenty.
The curious case of AGC 114905: an isolated galaxy devoid of dark matter?
Authors: McGaugh Stacy
Published: April 2024

It’s early in the new year, so what better time to violate my own resolutions? I prefer to be forward-looking and not argue over petty details, or chase wayward butterflies. But sometimes the devil is in the details, and the occasional butterfly can be entertaining if distracting. Today’s butterfly is the galaxy AGC 114905, which has recently been in the news.
Galaxy Stellar and Halo Masses: tension between abundance matching and kinematics
Authors: McGaugh Stacy
Published: April 2024

Mass is a basic quantity. How much stuff does an astronomical object contain?
How things go mostly right or badly wrong
Authors: McGaugh Stacy
Published: April 2024

People often ask me of how “perfect” MOND has to be. The short answer is that it agrees with galaxy data as “perfectly” as we can perceive – i.e., the scatter in the credible data is accounted for entirely by known errors and the expected scatter in stellar mass-to-light ratios. Sometimes it nevertheless looks to go badly wrong. That’s often because we need to know both the mass distribution and the kinematics perfectly.
Dwarf Satellite Galaxies and Low Surface Brightness Galaxies in the Field. I.
Authors: McGaugh Stacy
Published: April 2024

The Milky Way and its nearest giant neighbor Andromeda (M31) are surrounded by a swarm of dwarf satellite galaxies. Aside from relatively large beasties like the Large Magellanic Cloud or M32, the majority of these are the so-called dwarf spheroidals. There are several dozen examples known around each giant host, like the Fornax dwarf pictured above.
Astronomical Acceleration Scales
Authors: McGaugh Stacy
Published: April 2024

A quick note to put the acceleration discrepancy in perspective. The acceleration discrepancy, as Bekenstein called it, more commonly called the missing mass or dark matter problem, is the deviation of dynamics from those of Newton and Einstein. The quantity D is the amplitude of the discrepancy, basically the ratio of total mass to that which is visible.
An early result from JWST
Authors: McGaugh Stacy
Published: April 2024

There has been a veritable feeding frenzy going on with the first JWST data. This is to be expected. Also to be expected is that some of these early results will ultimately prove to have been premature. So –  caveat emptor!  That said, I want to highlight one important aspect of these early results, there being too many to do all them all justice.
The Hubble Constant from the Baryonic Tully-Fisher Relation
Authors: McGaugh Stacy
Published: April 2024

The distance scale is fundamental to cosmology. How big is the universe? is pretty much the first question we ask when we look at the Big Picture. The primary yardstick we use to describe the scale of the universe is Hubble’s constant: the H  0  in  v = H  0  D  that relates the recession velocity (redshift) of a galaxy to its distance. More generally, this is the current expansion rate of the universe.
Not quiet on the northern front
Authors: McGaugh Stacy
Published: April 2024

It has been two months since my last post. Sorry for the extended silence, but I do have a real job. It is not coincidental that my last post precedes the start of the semester. It has been the best of semesters, but mostly the worst of semesters. On the positive side, I’m teaching our upper level cosmology course. The students are great, really interested and interactive.
A Significant Theoretical Advance
Authors: McGaugh Stacy
Published: April 2024

The missing mass problem has been with us many decades now. Going on a century if you start counting from the work of Oort and Zwicky in the 1930s. Not quite a half a century if we date it from the 1970s when most of the relevant scientific community started to take it seriously. Either way, that’s a very long time for a major problem to go unsolved in physics.
Cop28 president not even trying to hide his obvious bias
Authors: McGaugh Stacy
Published: April 2024

In 1986, I was a grad student at Princeton, working in the atomic physics lab of Will Happer. It was at a department colloquium that I first heard a science talk that raised serious concerns about our use of fossil fuels potentially impacting the climate. This was not received well. People asked all sorts of questions, with much of the discussion revolving around feedback effects.
Does Newton’s Constant Vary?
Authors: McGaugh Stacy
Published: April 2024

This title is an example of what has come to be called Betteridge’s law. This is a relatively recent name for an old phenomenon: if a title is posed as a question, the answer is  no  . This is especially true in science, whether the authors are conscious of it or not.
A Response to Recent Developments Concerning the Gravitational Potential of the Milky Way
Authors: McGaugh Stacy
Published: April 2024

In the series of recent posts I’ve made about the Milky Way, I missed an important reply made in the comments by Francois Hammer, one of the eminent scientists doing the work. I was on to writing the next post when he wrote it, and simply didn’t see it until yesterday. Dr. Hammer has some important things to say that are both illustrative of the specific topic and also of how science should work.
Let’s just ignore it
Authors: McGaugh Stacy
Published: April 2024

Something that Sabine Hossenfelder noted recently on Twitter resonated with me: This is a very real problem in academia, and I don’t doubt that it is a common feature of many human endeavors. Part of it is just that people don’t know enough to know what they don’t know. That is to say, so much has been written that it can be hard to find the right reference to put any given fever dream promptly to never-ending sleep.
Define “better”
Authors: McGaugh Stacy
Published: April 2024

Dark matter remains undetected in the laboratory. This has been true for forever, so I don’t know what drives the timing of the recent spate of articles encouraging us to keep the faith, that dark matter is still a better idea than anything else. This depends on how we define “better.” There is a long-standing debate in the philosophy of science about the relative merits of accommodation and prediction.
The Acceleration Scale in the Data
Authors: McGaugh Stacy
Published: April 2024

One experience I’ve frequently had in Astronomy is that there is no result so obvious that someone won’t claim the exact opposite. Indeed, the more obvious the result, the louder the claim to contradict it. This happened today with a new article in Nature Astronomy by Rodrigues, Marra, del Popolo, & Davari titled  Absence of a fundamental acceleration scale in galaxies  . This title is the opposite of true.
When you have eliminated the impossible…
Authors: McGaugh Stacy
Published: April 2024

In previous posts, I briefly described some of the results that provoked a crisis of faith in the mid-1990s. Up until that point, I was an ardent believer in the cold dark matter paradigm. But it no longer made sense as an explanation for galaxy dynamics. It didn’t just not make sense, it seemed strewn with self-contradictions, all of which persist to this day.
Commentary on Wide Binaries
Authors: McGaugh Stacy
Published: April 2024

Last time, I commented on the developing situation with binary stars as a test of MOND. I neglected to enable comments for that post, so have done so now. Indranil Banik has shared his perspective on wide binaries in a talk on the subject that is available on Youtube, included below. Indranil and his collaborators are not seeing a MOND effect in wide binaries. Others have, as I discussed in the previous post.
The next cosmic frontier: 21cm absorption at high redshift
Authors: McGaugh Stacy
Published: April 2024

There are two basic approaches to cosmology: start at redshift zero and work outwards in space, or start at the beginning of time and work forward. The latter approach is generally favored by theorists, as much of the physics of the early universe follows a “clean” thermal progression, cooling adiabatically as it expands.
Dwarf Satellite Galaxies. II. Non-equilibrium effects in ultrafaint dwarfs
Authors: McGaugh Stacy
Published: April 2024

I have been wanting to write about dwarf satellites for a while, but there is so much to tell that I didn’t think it would fit in one post. I was correct. Indeed, it was worse than I thought, because my own experience with low surface brightness (LSB) galaxies in the field is a necessary part of the context for my perspective on the dwarf satellites of the Local Group.
The Angel Particle
Authors: McGaugh Stacy
Published: April 2024

The dominant paradigm for dark matter has long been the weakly interacting massive particle (WIMP). WIMPs are hypothetical particles motivated by supersymmetry. This is well-posed scientific hypothesis insofar as it makes a testable prediction: the cold dark matter thought to dominate the cosmic mass budget should be composed of a particle with a mass in the neighborhood of 100 GeV that interacts via the weak nuclear force – hence the name.
A post in which some value judgements are made about the situation with wide binaries
Authors: McGaugh Stacy
Published: April 2024

I have tried very hard to remain objective and even handed, but I find that I weary of the wide binary debate. I don’t know what the right answer will turn out to be. But I do have opinions. For starters, it is a big Galaxy. There is just too much to know. When I wrote about the Milky Way earlier this year, the idea was to set up an expectation value for wide binaries in the solar neighborhood.
What JWST will see
Authors: McGaugh Stacy
Published: April 2024

Big galaxies at high redshift! That’s my prediction, anyway. A little context first. New Year, New Telescope First, JWST finally launched. This has been a long-delayed NASA mission; the launch had been put off so many times it felt like a living example of Zeno’s paradox: ever closer but never quite there.
The arrogance of ignorance
Authors: McGaugh Stacy
Published: April 2024

A colleague points out to me a recent preprint by Bertone & Tait titled  A New Era in the Quest for Dark Matter  . Most of the narrative is a conventionalist response to the failure of experimental dark matter searches, posing a legitimate question in this context. Where do we take it from here? From  Bloom County  by Berkley Breathed.
Fuzzy Thing!
Authors: McGaugh Stacy
Published: April 2024

I was contacted today by a colleague at NASA’s Goddard Space Flight Center who was seeking to return some photographic plates of Halley’s comet that had been obtained with the Burrell Schmidt telescope. I at first misread the email – I get so many requests for data, I initially assumed that he was  looking  for said plates.
A pre-history of the prediction of the amplitude of the second peak of the cosmic microwave background
Authors: McGaugh Stacy
Published: April 2024

In the previous post, I wrote about a candidate parent relativistic theory for MOND that could fit the acoustic power spectrum of the cosmic microwave background (CMB). That has been a long time coming, and probably is not the end of the road. There is a long and largely neglected history behind this, so let’s rewind a bit. I became concerned about the viability of the dark matter paradigm in the mid-1990s.
Divergence
Authors: McGaugh Stacy
Published: April 2024

I read somewhere – I don’t think it was Kuhn himself, but someone analyzing Kuhn – that there came a point in the history of science where there was a divergence between scientists, with different scientists disagreeing about what counts as a theory, what counts as a test of a theory, what even counts as evidence. We have reached that point with the mass discrepancy problem.
A Stellar Population Mystery in a Low Surface Brightness Galaxy
Authors: McGaugh Stacy
Published: April 2024

This tongue-in-cheek quote is a statement of the obvious, at least for the 90+ years since Hubble established that galaxies are stellar systems comparable to and distinct from the Milky Way. There’s interstellar gas and dust too, and I suppose for nearly half that time, people have also thought galaxies to be composed of dark matter. But you can’t see that;
Predictive Power in Science
Authors: McGaugh Stacy
Published: April 2024

This is a wise truth that has often been poorly interpreted. I despise some of the results that this sports quote has had in American culture. It has fostered a culture of bad sportsmanship in some places: an acceptance, even a dictum, that the ends justify the means – up to and including cheating, provided you can get away with it. Winning every time is an impossible standard.
The MOND at 40 conference
Authors: McGaugh Stacy
Published: April 2024

I’m back from the meeting in St. Andrews, and am mostly recovered from the jet lag and the hiking (it was hot and sunny, we did not pack for that!) and the driving on single-track roads like Mr. Toad. The A835 north from Ullapool provides some spectacular mountain views, but the A837 through Rosehall is more perilous carnival attraction than well-planned means of conveyance. As expected, the most contentious issue was that of wide binaries.
Global climate basics
Authors: McGaugh Stacy
Published: April 2024

Last time, I expressed extreme disappointment that fossil fuel executives had any role in leading the climate meeting COP28. This is a classic example of putting the the fox in charge of the hen house. The issue is easily summed up: Setting aside economic self-interest and other human foibles, it is clear from the comments that the science is not as clear to everyone as it is to me. That’s fair;

Second peak bang on
Authors: McGaugh Stacy
Published: April 2024

At the dawn of the 21st century, we were pretty sure we had solved cosmology. The Lambda Cold Dark Matter (LCDM) model made strong predictions for the power spectrum of the Cosmic Microwave Background (CMB). One was that the flat Robertson-Walker geometry that we were assuming for LCDM predicted the location of the first peak should be at ℓ = 220.
Two Hypotheses
Authors: McGaugh Stacy
Published: April 2024

OK, basic review is over. Shit’s gonna get real. Here I give a short recounting of the primary reason I came to doubt the dark matter paradigm. This is entirely conventional – my concern about the viability of dark matter is a contradiction within its own context. It had nothing to do with MOND, which I was blissfully ignorant of when I ran head-long into this problem in 1994.
Recent Developments Concerning the Gravitational Potential of the Milky Way. II. A Closer Look at the Data
Authors: McGaugh Stacy
Published: April 2024

Continuing from last time, let’s compare recent rotation curve determinations from Gaia DR3: These are different analyses of the same dataset. The Gaia data release is immense, with billions of stars. There are gazillions of ways to parse these data. So it is reasonable to have multiple realizations, and we shouldn’t expect them to necessarily agree perfectly: do we look exclusively at K giants? A stars?

Recent results from the third data release (DR3) from Gaia has led to a flurry of papers. Some are good, some are great, some are neither of those. It is apparent from the comments last time that while I’ve kept my pledge to never dumb it down, I have perhaps been assuming more background knowledge on the part of readers than is adequate.

Wide binary debate heats up again
Authors: McGaugh Stacy

One of the most interesting and contentious results concerning MOND this year has been the dynamics of wide binaries. When last I wrote on this topic, way back at the end of August, Chae (2023) and Hernandez (2023) both had new papers finding evidence for MONDian behavior in wide binaries. Since that time, they each have written additional papers on the subject.

People seem to like to do retrospectives at year’s end. I take a longer view, but the end of 2020 seems like a fitting time to do that. Below is the text of a paper I wrote in 1995 with collaborators at the Kapteyn Institute of the University of Groningen. The last edit date is from December of that year, so this text (in plain TeX, not LaTeX!) is now a quarter century old. I am just going to cut & paste it as-was;

A brief history of the Radial Acceleration Relation
Authors: McGaugh Stacy
Published: April 2024

This expression exactly depicts the progression of the radial acceleration relation. Some people were ahead of this curve, others are still behind it, but it quite accurately depicts the mass sociology. This is how we react to startling new facts. For quotation purists, I’m not sure exactly what the original phrasing was.
Primer on Galaxy Properties

When we look up at the sky, we see stars. Stars are the building blocks of galaxies; we can see the stellar disk of the galaxy in which we live as the vault of the Milky Way arching across the sky. When we look beyond the Milky Way, we see galaxies. Just as stars are the building blocks of galaxies, galaxies are the building blocks of the universe.

I recently traveled to my first international meeting since the Covid pandemic began. It was good to be out in the world again. It also served as an excellent reminder of the importance of in-person interactions. On-line interactions are not an adequate substitute. I’d like to be able to recount all that I learned there, but it is too much. This post will touch on one of the much-discussed topics, our own Milky Way Galaxy.

Perhaps the most compelling astronomical phenomenon accessible to a naked-eye observer is a total eclipse of the sun. These rare events have always fascinated us, and often terrified us.

This post is a recent conversation with David Garofalo for his blog.  Today we talk to Dr. Stacy McGaugh, Chair of the Astronomy Department at Case Western Reserve University.   David  : Hi Stacy.

Is NGC 1277 a problem for MOND?
Authors: McGaugh Stacy
Published: April 2024

Alert reader Dan Baeckström recently asked about NGC 1277, as apparently some people have been making this out to be some sort of death knell for MOND. My first reaction was NGC who? There are lots of galaxies in the New General Catalog (new in 1888, even then drawing heavily on earlier work by the Herschels). I’m well acquainted with many individual galaxies, and can recall many dozens by name, but I do not know every single thing in the NGC.

Avi Loeb has a nice recent post  Recalculating Academia  , in which he discusses some of the issues confronting modern academia. One of the reasons I haven’t written here for a couple of months is despondency over the same problems. If you’re here reading this, you’ll likely be interested in what he has to say. I am not eager to write at length today, but I do want to amplify some of the examples he gives with my own experience.
OSIRIS-REx returns safely
Authors: McGaugh Stacy
Published: April 2024

Taking a break from galaxies and cosmology, I’d like to post a little praise of NASA for safely returning a piece of an asteroid to Earth. One of the amazing things to me about astronomy & astrophysics is that we have learned how to decipher the composition of distant stars and gas clouds by observing their spectra. I worked on this early in my career and retain an interest in the cosmic abundance of the elements.
Ain’t no cusps here
Authors: McGaugh Stacy
Published: April 2024

It has been twenty years since we coined the phrase NFW halo to describe the cuspy halos that emerge from dark matter simulations of structure formation. Since that time, observations have persistently contradicted this fundamental prediction of the cold dark matter cosmogony. There have, of course, been some theorists who cling to the false hope that somehow it is the data to blame and not a shortcoming of the model.
Leveling the Playing Field of Dwarf Galaxy Kinematics
Authors: McGaugh Stacy
Published: April 2024

We have a new paper on the arXiv. This is a straightforward empiricist’s paper that provides a reality check on the calibration of the Baryonic Tully-Fisher relation (BTFR) and the distance scale using well-known Local Group galaxies. It also connects observable velocity measures in rotating and pressure supported dwarf galaxies: the flat rotation speed of disks is basically twice the line-of-sight velocity dispersion of dwarf spheroidals.
Question of the Year (and a challenge)

Is the Milky Way’s rotation curve declining?
Authors: McGaugh Stacy
Published: April 2024

Yes, some. That much is a step forward from a decade ago, when a common assumption was that the Milky Way’s rotation curve remained flat at the speed at which the sun orbited. This was a good guess based on empirical experience with other galaxies, but not all galaxies have rotation curves that are completely flat, nor can we be sure the sun is located where that is the case.

يهدف هذا البحث إلى دراسة تأثير تطبيق الإفصاح المحاسبي وفقاً لمعايير إعداد التقارير المالية الدولية (IFRS) على تقليل المخاطر المالية للبنوك المُدرجة في سوق الأوراق المالية العراقية. إذ يعتبر تحقيق الهدف الأساسي للإفصاح المالي وغير المالي هو تمكين جميع أصحاب المصلحة من فهم أداء الشركة ووضعها المالي، مما يسهم في مساعدتهم على اتخاذ قرارات اقتصادية سليمة. وتعتمد جودة الإفصاح على المعايير المحاسبية المُعتمدة لإعداد البيانات المالية. ومن جراء التباين بين المعايير المحاسبية في مختلف البلدان بسبب العوامل المؤسسية، فقد سعت لجنة إعداد المعايير الدولية لإعداد التقارير المالية إلى وضع معايير تناسب بيئة التطبيق في معظم البلدان بهدف تحسين نوعية وقابلية مقارنة المعلومات المحاسبية.

كما يهدف هذا البحث إلى استكشاف ما إذا كان تطبيق الإفصاح المحاسبي وفقاً لمعايير IFRS يقلل من مخاطر الائتمان والسيولة والسوق بالنسبة للبنوك العراقية.

استخدم الباحث المنهج الوصفي التحليلي من خلال جمع البيانات لاستكمال الجوانب النظرية ثم اعدا استبيان يخض الجانب العملي.

يشمل مجتمع البحث البنوك المُدرجة في سوق الأوراق المالية في العراق. سيتم توزيع الاستبيانات على المحاسبين ومديري حسابات البنوك والمديرين الماليين في عينة من تلك البنوك في بغداد والتي تمكن الباحث من الوصول إليها.

تشير النتائج إلى وجود علاقة عكسية بين التزام البنوك بمعايير المحاسبة الدولية لإعداد التقارير المالية وبين كل من مخاطر السيولة ومخاطر الائتمان ومخاطر السوق، يُعزز هذا التزام وجود تقديرات دقيقة عند منح القروض، وتأكيد توفر الاحتياطيات المالية لإدارة التعثر في سداد القروض تسهم اعتماد البنوك لهذه المعايير في التصدي للطلب المفاجئ على السيولة وتحويل الأصول إلى نقد بسرعة.

توصل الباحث إلى مجموعة من التوصيات تشمل إصدار لوائح حكومية للإفصاح والاستفادة من الخبرات الدولية، وضرورة الإفصاح عن حقوق الملكية بشكل كامل، والالتزام بالمعايير الدولية عند عرض البيانات المالية، كما أكد البحث على أهمية الحوكمة والشفافية وتوافر السيولة في الوقت المناسب لمواجهة الطلب المفاجئ على سداد الالتزامات مما يخفض من المخاطر التي قد تتعرض لها المصارف العراقية المدرجة في سوق الأوراق المالية

Licitud restrictiva acerca del Control de identidad policial
Authors: Enriquez Chipana Jorge Enrique
Published: April 2024

Con el objetivo de comprender las razones que fundamentan el ordenamiento legal, jurisprudencia que legitiman la atribución policial para restringir la libertad a través del control de identidad policial en el Perú, se realizó un estudio teórico mediante la revisión de la normativa y material bibliográfico sobre la temática. Con la revisión de los anuarios estadísticos policivos publicados, año 2020 y 2021, se observa que se ejecutaron 199.292 operativos por control de identidad policial (99,768 y 99524, respectivamente), evidenciando que tal «indicador» es el más productivo en el sector Interior, aunque la realidad muestra que es el menos estudiado y exiguo en publicaciones. Así pues, tal actuación policial encuentra reconocimiento en el artículo 205 del Código Procesal Penal, con fundamentación constitucional en el artículo 2.24.b y 166, como resultado de su aplicación se presentaron sendos proyectos de ley para su derogación por considerarlo inconstitucional, lo cual no prosperó, advirtiéndose su débil estudio temático.

Incompatibilidad de los requerimientos fiscales para la declaración de agentes de inteligencia de la Dirección General de Inteligencia en procesos de delitos de corrupción
Authors: Ponce Gutiérrez Bárbara , Matsuno Mercedes
Published: April 2024

En atención a los reiterados llamados a declarar de los agentes de Inteligencia, el objetivo de este artículo se centra en analizar cómo la incompatibilidad de los requerimientos fiscales para la declaración en procesos por delitos de corrupción de funcionarios afecta las labores de inteligencia en los agentes de la Dirección General de Inteligencia del Ministerio del Interior (Digimin) en procesos de delitos de corrupción. Para los fines, la investigación sigue un enfoque cualitativo, y un diseño fenomenológico. Consideró una muestra de 7 funcionarios de la Digimin tratándose de una muestra intencional no probabilística. Por técnica se empleó la entrevista semiestructurada y como instrumento una guía de entrevista. Los principales hallazgos exponen la falta de articulación entre la Digimin y el Ministerio Público, existiendo pruebas inadecuadas o conductas indebidas que restan legitimidad a las indagaciones, siendo ineficaz la Ley Nº 30077 y su reglamento. En cuanto al Decreto Legislativo N° 1141 de Fortalecimiento y Modernización del Sistema Nacional de Inteligencia, no existen procedimientos explícitos que favorezcan a los agentes. Asimismo, las restricciones en su administración y financiación dan lugar a vicios legales, y de procedimientos que vulneran los derechos de las autoridades encargadas de proteger esta labor. Se concluye que, el sistema de justicia penal debe utilizar procedimientos especializados de investigación con el fin de localizar, indagar, organizar, reunir y obtener pruebas suficientes para condenar y sancionar a las personas que violen determinados bienes jurídicos protegidos, sin necesidad de que los agentes de inteligencia deban ser llamados a declarar.
