A force feedback interface including a haptic accelerator that relieves the computational burden associated with force feedback generation from a force feedback processor. The force feedback processor is preferably a device microprocessor included in the interface device and separate from a controlling host computer for determining forces to be output. The haptic accelerator quickly determines velocity and/or acceleration information describing motion of a user manipulatable object from raw position data received from sensors of the interface device and representing the position of the user object. The velocity and/or acceleration data is used by the force feedback processor in the determination of forces to be output on the user object. The haptic accelerator can in some embodiments also quickly and reliably determine condition forces which depend on the motion of the user object, thus relieving additional computation burden from the force feedback processor and permitting the force feedback processor

In the physiology of the kidney, tubuloglomerular feedback (TGF) is a feedback system inside the kidneys. Within each nephron, information from the renal tubules (a downstream area of the tubular fluid) is signaled to the glomerulus (an upstream area). Tubuloglomerular feedback is one of several mechanisms the kidney uses to regulate glomerular filtration rate (GFR). It involves the concept of purinergic signaling, in which an increased distal tubular sodium chloride concentration causes a basolateral release of adenosine from the macula densa cells. This initiates a cascade of events that ultimately brings GFR to an appropriate level. The kidney maintains the electrolyte concentrations, osmolality, and acid-base balance of blood plasma within the narrow limits that are compatible with effective cellular function; and the kidney participates in blood pressure regulation and in the maintenance of steady whole-organism water volume Fluid flow through the nephron must be kept within a narrow range ...
Hey Jennie. I see your point of view and understand why it can be confusing. The reason wound healing is considered a positive feedback mechanism is because the output enhances the original stimulus. If a cut occurs, the body sends platelets and cells to the site. The platelets and cells fight invading pathogens and produce a clot. When the clot forms and the wound heals, the inflammation response and output end. Negative feedback changes a variable back to its original value and is constantly adjusting within the body. If your temperature is to high, a negative feedback loop works to lower it. If your temperature is low, it will bring it back up. Its a balancing act. Positive feedback only occurs in certain situations and has an ending, it does not constantly adjust. If you get a cut, a positive feedback loop works to heal it, then it stops. If you go into labor, the loop continues until you deliver, then its over and you go back to your original state. Think if you werent pregnant but felt ...

Combined T(3)/T(4) therapy--In thyroidectomized patients, the L-T(4)-only replacement doses needed to normalize plasma T(3) or average tissue T(3) were 145 microg L-T(4)/day or 165 microg L-T(4)/day, respectively. The combined T(4) + T(3) dosing needed to normalize both plasma and tissue T(3) levels was 105 microg L-T(4) + 9 microg T(3) per day. For all three regimens, simulated mean steady-state plasma thyroid-stimulating hormone (TSH), T(3), and T(4) was within normal ranges (TSH: 0.5-5 mU/L; T(4): 5-12 microg/dL; T(3): 0.8-1.9 ng/mL). Parenteral T(4) administration--800 microg weekly or 400 microg twice weekly normalized average tissue T(3) levels both for subcutaneous (SC) and intramuscular (IM) routes of administration. TSH, T(3), and T(4) levels were maintained within normal ranges for all four of these dosing schemes (1x vs. 2x weekly, SC vs. IM). Central hypothyroidism--We simulated steady-state plasma T(3), T(4), and TSH concentrations in response to varying degrees of central ...
Tailored feedback was rated as more relevant, and was more likely to be shown to the GP than the generic feedback. Given that the tailored feedback included personalised risk factor information, it is not surprising that it was rated as more relevant. Almost two-thirds of participants given the tailored feedback indicated that they either showed the feedback to their GP or it gave them some ideas about what to ask the doctor, compared to less than half of those who received generic feedback. Anecdotally, the tailored feedback prompted a greater response from participants than the generic feedback, including several who were surprised by their recommended healthy weight, and one participant who commented that seeing her depression score prompted her to bring this up with her GP. However, participants did not rate the tailored feedback as any more likely to help them improve their health, or any easier to understand, than the generic feedback.. The type of feedback did not appear to influence ...

Feedback loops, both positive and negative are embedded in the Mitogen Activated Protein Kinase (MAPK) cascade. In the three layer MAPK cascade, both feedback loops originate from the terminal layer and their sites of action are either of the two upstream layers. Recent studies have shown that the cascade uses coupled positive and negative feedback loops in generating oscillations. Two plausible designs of coupled positive and negative feedback loops can be elucidated from the literature; in one design the positive feedback precedes the negative feedback in the direction of signal flow and vice-versa in another. But it remains unexplored how the two designs contribute towards triggering oscillations in MAPK cascade. Thus it is also not known how amplitude, frequency, robustness or nature (analogous/digital) of the oscillations would be shaped by these two designs. We built two models of MAPK cascade that exhibited oscillations as function of two underlying designs of coupled positive and negative
Definition of feedback regulation in the Financial Dictionary - by Free online English dictionary and encyclopedia. What is feedback regulation? Meaning of feedback regulation as a finance term. What does feedback regulation mean in finance?
In a mobile communication system, receivers measure channel characteristics using a received reference channel signal. The receivers determine a weight which has orthogonality with respect to each of a preset number of weight vectors in the mobile communication system and has the highest signal-to-interference-and-noise ratio, and feedback the weight and the corresponding signal-to-interference-and-noise ratio to the transmitter. The transmitter interprets the feedback information output from the receivers and determines receivers having feedback information which are orthogonal to each other and have the maximum throughput as an addition capacity when transmitted simultaneously, and determines weights based on the feedback information of the receivers having the maximum throughput. By applying the determined weights to the antennas using a well-known beam forming scheme, data can be transmitted to each of the determined receivers. Therefore, the
The distribution of motivations will be used (alongside other research, data, and feedback) to determine how to present and prioritize existing or non-existent features in this feedback system - including but not limited to: feedback input (here, star ratings on 4 metrics); feedback summary (here, bar graph for each metric); feedback output (potentially reviews, comments, messages to editors, lists, updates to profile pages, and on). Responses to this answer will also highlight areas where further research and design thinking needs to take place (for example, if we see a significant bias in motivations to "opinion sharing" we will further explore iterations on the interface or new interface elements that lead to a richer opinion sharing experience ...
318027337 - EP 2153025 A2 2010-02-17 - REAL TIME CLOSED LOOP INTERPRETATION OF TUBING TREATMENT SYSTEMS AND METHODS - [origin: WO2008152599A2] A technique facilitates the treatment of a subterranean formation. The technique involves the use of a fluid delivery system that comprises a continuous feedback system. The continuous feedback system utilizes a real time closed loop interpretation technique to instantaneously synchronize and adjust actions at a well site surface relative to measured downhole events. Sensors are used to monitor at least one downhole property in real time. Based on the real time data, the continuous feedback system enables adjustments to be made with respect to the at least one property in a manner designed to influence a downhole event.[origin: WO2008152599A2] A technique facilitates the treatment of a subterranean formation.

In rainbow trout, bilateral castration at any stage of the testicular cycle, including the, period when the testes are inactive, increases plasma GtH levels (Billard, Richard and Breton, 1.976, 1977; Billard, 1978a). These results indicate that the negative feedback action of testicular steroids on GtH secretion occurs at all stages in the breeding cycle. Sex steroids are taken up and sequestered in the pituitary, the NPO, the nucleus lateralis tuberis (NLT), the nucleus recessus lateralis and other locations in the brain in many species of fishes, suggesting that a number of sites in the brain can serve as loci for feedback action of sex steroids (Kim. et al., 1978; Peter and Crim, 1979). In the sexually mature female goldfish, serum GtH levels increase markedly following implantation of antiestrogens in the pituitary, whereas similar implants in the NLT area result only in a modest GtH increase and have no effect when implanted elsewhere (Billard and Peter, 1977). Thus the NLT and pituitary ...
The invention relates to a device for the representation and determination of the rigidity of materials, by means of which measured physical values can be represented at a vicinity distant from the place of measurement and above all by means of a tactile representation, in other words, using the sense of touch. According to the invention, a force feedback system has been developed which permits the user or operator to gain a feeling for the mechanical rigidity value. The value for rigidity, measured for example for medical purposes by endoscope or arthroscope, controls the pressure found in an external touch cushion (2), by means of one of the voltages (U), given by an analytical device recording the appropriate test region. The rigidity of the cushion (2) thus gives an equivalent feel to the measured rigidity of the material under evaluation, or the biological probe. In the above rigidity transmitter (1) a pressure (P) is generated in a closed pressure system by means of an input converter (3) and
Support Feedback = = Introduction = From time to time, issues or conflicts arise in support channels. We should have a documented process for listening to feedback and acting on it where possible. This document is oriented to irc support (specifically the #fedora support channel), but could be expanded to cover other support areas (mailing lists / forums). = Current #fedora feedback = The current method of feedback is via irc, in the #fedora-ops channel, and after that in email to the irc-support-operators group in fas. The current setup for feedback of support in #fedora has a number of problems: * Its not really documented at all. * Feedback is done right after events that raised the issue, so everyone is emotional and "hot" about it. * Both the person wanting to provide the feedback and possibly people they wish to provide feedback about are in all these avenues, possibly leading to back and forth and heated exchanges between them. * Since feedback is done directly, there is no way to just ...
In general, the prediction process is one of identifying the current state of the system, and making a prediction for some as yet uncomputed value based on that state. Prediction accuracy is improved by learning what is a good prediction for that state using a feedback process at the time the predicted value is actually computed. While there have been a number of efforts to formally characterize this process, we have taken the approach of providing a simple algebraic-style notation that allows one to express this state identification and feedback process. This notation allows one to describe a wide variety of predictors in a uniform way. It also facilitates the use of an efficient search technique called genetic programming, which is loosely modeled on the natural evolutionary process, to explore the design space. In this paper we describe our notation and the results of the application of genetic programming to the design of branch and indirect jump predictors. ...
Ready to ship: Within cells displaying features of Alzheimers, the researchers found high concentrations of WAVE1 and the amyloid-β precursor protein within the Golgi, an organelle in which proteins are packaged for shipping. These appear in the cell above as bright, yellow clusters.. "Our discovery centers on a protein called WAVE1, which we found to be important in the production of amyloid-β. The reduction of WAVE1 appears to have a protective effect against the disease," says study author Paul Greengard, Vincent Astor Professor and head of the Laboratory of Molecular and Cellular Neuroscience. "When levels of amyloid-β rise, there is an accompanying increase in another molecule, AICD, which reduces the expression of WAVE1. This has the effect of reducing the production of amyloid-β.. "By targeting steps within this newly discovered pathway," he adds, "it may be possible to develop drugs to reduce amyloid-β that potentially could be used to either treat or prevent Alzheimers ...
We introduce here a simple finite-dimensional feedback control scheme for stabilizing solutions of infinite-dimensional dissipative evolution equations, such as reaction-diffusion systems, the Navier-Stokes equations and the Kuramoto-Sivashinsky equation. The designed feedback control scheme takes advantage of the fact that such systems possess finite number of determining parameters (degrees of freedom), namely, finite number of determining Fourier modes, determining nodes, and determining interpolants and projections. In particular, the feedback control scheme uses finitely many of such observables and controllers. This observation is of a particular interest since it implies that our approach has far more reaching applications, in particular, in data assimilation. Moreover, we emphasize that our scheme treats all kinds of the determining projections, as well as, the various dissipative equations with one unified approach. However, for the sake of simplicity we demonstrate our approach in this
Phosphorylation of NEUROG3 Links Endocrine Differentiation to the Cell Cycle in Pancreatic Progenitors Scientists demonstrated that neurogenin 3 (NEUROG3) is phosphorylated within the nucleus on serine 183, which catalyzes its hyperphosphorylation and proteosomal degradation. During progression through the progenitor cell cycle, NEUROG3 phosphorylation is driven by the actions of cyclin-dependent kinases 2 and 4/6 at G1/S cell-cycle checkpoint. [Dev Cell] Abstract , Graphical Abstract Prolonged Elimination of Negative Feedback Control Mechanisms along the Insulin Signaling Pathway Impairs β Cell Function In Vivo Investigators examined the effects of mutation of five inhibitory Ser phosphorylation sites on insulin receptor substrate 2 (IRS2) function in transgenic mice that overexpress, selectively in pancreatic β cells, either wild-type (WT) or a mutated IRS2 protein (IRS25A). Islets size, number, and mRNA levels of catalase and superoxide dismutase, were increased, while those of nitric ...
Background: Murine double minutes-2 (MDM2) protein plays a key role in physiological processes like growth arrest, senescence and apoptosis. MDM2 negatively regulates key proteins like p53 by inhibiting its transcriptional activity and promoting its proteosomal degradation through ubiquitinylation. In turn, the MDM2 expression is regulated in part by a p53-responsive promotor. This negative feedback control mechanism assures that both p53 and MDM2 are kept at very low levels in proliferating cells. However, in about half of all human tumors, the normal regulation of p53 might be disrupted through direct overexpression of MDM2 caused by e.g. MDM2 gene amplification or a T to G substitution (SNP309) in the promotor region of MDM2. High resolution melting analysis (HRMA) provides a valid approach to efficiently detect DNA mutations. The current study aimed at validating and implementing HRMA for screening of colorectal cancer patients (CRC) to detect MDM2 promotor SNP309. Pyrosequencing was used to ...
A process, apparatus, and method for online control and database collection and management of a computerized detection, tracking, and feedback control system. The system tests for nutrients by Raman scattering effects on skin or other tissues to determine the content of carotenoids or other nutrients as evidenced in that skin. Serum levels of nutrients may vary dramatically with time, but skin tissues may average such nutrition over time. Skin and other tissues may be scanned with light to produce accurate measurements of carotenoids or other nutrients accumulated in the skin based on the Raman scattering affect of those nutrients in the skin. A score can be derived from a properly calibrated bio-photonic scanner to reflect an averaged effective uptake of the detected nutrient (e.g. such as the carotenoid example).

The guidelines and suggestions from these resources are summarized in the following list of effective evaluation practices:. 1. Clearly communicate evaluation criteria to supervisees and develop a mutually agreed upon written contract reflecting these criteria.. 2. Identify and communicate supervisee strengths and weaknesses. The Ethical Guidelines for Counsellor Supervisors (ACES, 1993) recommend that supervisors provide supervisees with ongoing feedback on their performance. This performance feedback establishes for supervisees a clear sense of what they do well and which skills need to be developed. Supervisee strengths and weaknesses can be evaluated in terms of process, conceptual, personal, and professional skills (Bernard R Goodyear, 1992, p. 42).. 3. Use constructive feedback techniques during evaluations. Supervisees are more likely to hear corrective feedback messages when these are preceded by positive feedback, focussed on observable behaviours, and are delayed until a positive ...
The long-held concept of a proportional negative feedback control between the thyroid and pituitary gland requires reconsideration in the light of more recent studies. Homeostatic equilibria depend on dynamic interrelationships between thyroid hormones and pituitary thyrotropin (TSH). They display a high degree of individuality, thyroid-state-related hierarchy and adaptive conditionality. Molecular mechanisms involve multiple feedback loops on several levels of organization, different time scales and varying conditions of their optimum operation, including a proposed feedforward motif. This supports the concept of a dampened response and multistep regulation, making the interactions between TSH, FT4 and FT3 situational and mathematically more complex. As a homeostatically integrated parameter, TSH becomes neither normatively fixed nor a precise marker of euthyroidism. This is exemplified by the therapeutic situation with L-thyroxine (L-T4) where TSH levels defined for optimum health may not apply

A level biology students need to be able to explain the principles of homeostasis through detailed understanding of feedback systems. Students need to understand the importance of maintaining the internal environment within restricted limits and the implications of these conditions not being met.. They need to be able to explain what is meant by both negative and positive feedback, be able to explain the general stages in negative feedback and clearly articulate the differences between positive and negative feedback systems.. Regulation of temperature, pH and blood sugar levels are particular examples that students will be expected to describe and explain in detail.. Kidney function is often included within this topic area, with students required to know about the processes of ultrafiltration and reabsorption and to be able to explain the role of the loop of Henle and the counter current multiplier mechanism. This is often a difficult concept for students and does rely on a prior understanding ...
As university lecturers, we often struggle to provide our students with good quality feedback in a consistent manner. This is usually caused by the increasing imbalance in teacher-student ratios (Hounsell et al., 2008), as well as the pressure of academic life and the lack of time (Sadler, 2010). In addition, assessment practices should be transparent enough to ensure all students are evaluated in a similar way (ODonovan et al., 2004), especially when different instructors teach different groups of students taking the same course. This paper, which focuses on designing a feedback scheme that helps instructors to provide good quality feedback in a consistent manner, begins with a needs analysis based on the authors experience as an instructor of academic writing in English. A literature review follows, focusing on: (a) the scholarship on feedback in higher education; and (b) the research on the use of technology for the provision of feedback. Finally, a feedback scheme is presented, and some ...
As a reminder, the PQRS Feedback Reports reflect the existing PQRS requirements under current law except for the adjustment summary section. The adjustment summary section has been revised to reflect the CY 2018 MPFS proposed rule, which proposes to reduce the required number of reporting measures submitted for 2016 PQRS from nine to six.. The QRURs are based on the proposals in the 2018 MPFS proposed rule. CMS proposes to hold physicians harmless from downward payment adjustments from 2016 VBPM quality tiering if they satisfy the requirements for PQRS. If the policies are not finalized as proposed, CMS will provide updated reports to recipients. The final rule is expected to be released in early November.. To access your reports:. ...

A few things occur to me.. 1) I like the OP Davids idea and agree it would be a good to include some delay into the Feedback process when buyers are making a "knee-jerk" reaction and leaving neutral or negative. Clearly a seller should be informed of an issue and be given the right and time to make good. I have noticed that whilst rare, when I do get a poor comment or rating it is usually timed at about when the buyer has returned home from work (bad day in the office!) or around midnight (after the pub!). Upon receiving these I always contact the buyer (never immediately, let them calm down first!) and on most occasions the issue is quickly resolved to their complete satisfaction. So, what then to do about the Feedback rating or snotty comment…... 2) Well, having resolved the issue and pleased the buyer, one problem with the current system is a seller can not submit a Feedback Revision Request for a neutral rating or positive rating with a snotty comment (aka false positive).

TY - JOUR. T1 - Feedback Control of an Achiral Robotic Microswimmer. AU - Kei Cheang, U.. AU - Kim, Hoyeon. AU - Milutinović, Dejan. AU - Choi, Jongeun. AU - Kim, Min Jun. PY - 2017/4/1. Y1 - 2017/4/1. N2 - Magnetic microswimmers are useful for navigating and performing tasks at small scales. To demonstrate effective control over such microswimmers, we implemented feedback control of the three-bead achiral microswimmers in both simulation and experiment. The achiral microswimmers with the ability to swim in bulk fluid are controlled wirelessly using magnetic fields generated from electromagnetic coils. The achirality of the microswimmers introduces unknown handedness resulting in uncertainty in swimming direction. We use a combination of rotating and static magnetic fields generated from an approximate Helmholtz coil system to overcome such uncertainty. There are also movement uncertainties due to environmental factors such as unsteady flow conditions. A kinematic model based feedback ...

Process operations often involve transitions between operating modes, which are typically described by their own dynamic models, constraints and specifications. Developing a formal theoretical framework and efficient computational tools to deal with such operational issues pose a formidable challenge. In the paper, we give an overview of recent key developments in this direction, involving (i) modeling of hybrid systems, exhibiting both continuous and discrete dynamics, to rigorously represent complex operations, and (ii) parametric programming mathematical and computational tools, to design optimal feedback control laws for constrained linear dynamic systems, in the context of model predictive control principles. Applications to a wide range of industrial problems will be discussed ...
You know that user feedback is crucial - after all, your users will decide whether your app succeeds or not - but how do you know whether users are being fair and objective in their feedback? We can tell you: They wont be. All of your users will be giving you biased feedback. They cant help it. When soliciting and listening to user feedback, you will inevitably run into bias on both sides of the coin: Biases will influence the people providing feedback, and your own biases will influence the way you receive that feedback. Its important to be aware of this, especially when reviewing comments about your user experience (UX). Accurate and unbiased feedback is essential to developing the best possible version of your app1. Although you cant erase your own biases (or those of your users), you can take steps to overcome common biases once you know what they are and how they might appear. The next time you ask your users for input, keep bias in mind and evaluate how you respond to users comments. Is your
A ballast circuit for a gas discharge lamp of the type including resistively heated cathodes includes a resonant load circuit incorporating a gas discharge lamp and including first and second resonant impedances whose values determine the operating frequency of the resonant load circuit. Further included is a d.c.-to-a.c. converter circuit coupled to the resonant load circuit so as to induce an a.c. current in the resonant load circuit. The converter includes first and second switches serially connected between a bus conductor at a d.c. voltage and ground, and has a common node through which the a.c. load current flows. A feedback circuit provides a feedback signal indicating the level of current in the resonant load circuit. A high voltage IC drives the first and second switches at a frequency determined by a timing signal which predominantly comprises the feedback signal during lamp ignition, whereby during lamp ignition the feedback signal causes the high voltage IC to drive the first and second
There has been a lot of research looking at the effect that extrinsic feedback and excessive extrinsic feedback has on learning. Salmoni et al (1984) suggested the guidance hypothesis. This hypothesis suggests that even though recurrent feedback provided during practice is beneficial to the learner in order to choose the correct responses, it blocks the processing of other sources of important information that are essential in order to obtain an internal depiction of the movement task that is capable of generating the movement when the feedback is stopped. Faded schedule feedback was a type of feedback tested to see if this would reduce participant dependency on extrinsic feedback. Winstein et al (1990) performed a study which contained two groups. One group received extrinsic feedback for every trial, while the other group used a faded feedback schedule and had a reduced frequency of feedback (50% of the trials). The results showed that the faded feedback group were able to sustain performance ...
A method and apparatus for measuring and enhancing the neuro-motor coordination of humans and animals includes generation of a non-visual periodic reference signal that is supplied to the user. A response is received from the user of that users perception of an occurrence of the periodic reference signal. A non-visual feedback signal is derived as a function of the occurrence of the reference signal and the user response. The non-visual feedback signal is supplied to indicate to that user the temporal relationship of the users response and the occurrence of the periodic reference signal. The non-visual signal may be in the form of an audio feedback signal or may be a tactile feedback signal.
Recently many members have been requesting a feedback system for the Marketplace, so today we are pleased to announce the introduction of the XDA-Developers Feedback system, based on iTrader. Using this system, you can leave feedback on your transactions carried out in the XDA-Developers marketplace, and other users can use this to decide whether or not to trust a user they are considering a transaction with.. We would like to remind you that, per the Marketplace rules, XDA-Developers is not responsible for any transaction, and everything undertaken is at your own risk. So without further ado, head over to the Marketplace Feedback System thread for more information about how the system works, and the rules for using it.. ...
Feedback only has an impact if the students actually read it. How often do we put comments on student papers and they never look at it? Not only are students more likely to read comments if the feedback is left during the process rather than after the process, students are more likely to learn from it. Once a student thinks they are done the impact of the comment can just roll off the student, they do not need that information anymore. They are hyperfocusing on their score rather than really internalizing the feedback. Without a score to focus on, feedback before the student thinks they are done allows the student to focus on the feedback. The feedback is FORMATIVE rather than punitive. ...
Providing the right kind of feedback to students can make a significant difference in their achievement. There are two key considerations. First, feedback that improves learning is responsive to specific aspects of student work, such as test or homework answers, and provides specific and related suggestions. There needs to be a strong link between the teacher comment and the students answer, and it must be instructive. This kind of feedback extends the opportunity to teach by alleviating misunderstanding and reinforcing learning. Second, the feedback must be timely. If students receive feedback no more than a day after a test or homework assignment has been turned in, it will increase the window of opportunity for learning. Feedback is a research-based strategy that teachers, and students, can practice to improve their success. | Learning, Teaching & Leading Today
A method and apparatus for shaping force signals for a force feedback device. A source wave is provided and is defined by a set of control parameters (including a steady state magnitude, a frequency value and a duration value) and modified by a set of impulse parameters (including an impulse magnitude, and a settle time representing a time required for the impulse magnitude to change to the steady-state magnitude). Optionally, application parameters specifying a direction of force signal and trigger parameters specifying activating buttons can also be provided for the source wave. Using a host processor or a local processor, the force signal is formed from the source wave and the sets of control parameters and impulse parameters, where the force signal includes an impulse signal followed by a continual steady-state signal after an expiration of the settle time. A feel sensation is generated to a user of the force feedback device as physical forces produced by actuators on the force feedback device in
In the private sector, platforms like Yelp, Amazon.com, and Kickstarter are giving increasing power to consumers. These tools create an ongoing process of suggestion and response-a "feedback loop"-- that motivates companies to listen to consumers and to create new and better products.. But why havent feedback loops given people more power in how they are governed, how donor money is spent, and how social services are delivered? People best understand the issues that affect them and what support they need to solve those problems, but many institutions struggle to understand and respond to their perspective. In many places, power imbalances and cultural practices discourage people from giving feedback at all. As a result, trillions of donor dollars and incredible human energy have been spent with good intentions on social projects, while many of the worlds most dire problems remain unsolved..

There are six different stakeholder groups you should be listening to periodically to determine whether youre moving in the right direction. These six groups are:. 1. Customers: How your customers see you is critical to any organization. Since not all feedback systems work equally to uncover customer perceptions, you should use a variety of feedback systems. Some examples are suggestion cards, phone calls, emails, interviews, focus groups, and so on.. 2. Employees: You should to track your employees level of engagement and satisfaction.
