Hello Everyone!
I started a PhD 2 years ago and I finished my first research paper. However, I couldn’t get any review on it. For me it is very important to have a feedback on it and learn.
My paper is bridging entrepreneurship with psychology. I studied how emotions conveyed by gesture influence juries‘ decision-making during funding pitch.
Please let me know if you have any suggestions on how I could get my paper reviewed and I am also keen to know whether it is possible to have a kind of tutoring on this.
Thank you!

Dear Energy and Environmental Researchers,
Kindly assist with me with yearly Environmental Performance Index (EPI) data from 1980 to 2020. I checked the SEDAC website but it appears only EPI for year 2020 is available.
Please if you have YEARLY time series from 1980 to 2020, I will appreciate if you can share. I am also open to collaborating with you using the data as a way of reciprocating the gesture.

For an upcoming study, I am in search of a quick Spanish placement test that can be made by L2 learners (preferably online) to determine their L2 Spanish proficiency level.
Ideally, the test would not be longer than 10 minutes and can be used for free, but please also contact me with recommendations for longer or paid tests. These could still be a useful starting point for us.

Been reviewing and reading articles which all claim to use AI to identify movement patterns in animals and humans but seem to miss the key point, that CNS activity and the output seen as a motor event like walking or speech differ in temporal scales. Neuronal firing is always in milliseconds while the output or endpoint (motor event) is in seconds even when at its best.
Another key issue is that the signal recorded along axons and sites away from source are have a delay as these signals are not transmitted at the speed of light, but each axon has its own conduction velocity and it matters!!
Neurophysiologists have been examining these things for over a century now, so please do check some of the matter before jumping to conclusion, this is also for the reviewers.

I was wondering if some primate vocalizations, hand gestures, etc. are universal. For example, a thumbs up in America means doing good, in other countries even if you don't know what they mean exactly, they can see that it means something good. I was wondering since humans are such close relatives to primates especially chimpanzees and bonobos, has any research been done on if some vocalizations and/or hand gestures are universally understood between all nonhuman primates, or do species have their own vocalizations and/or hand gestures that are unique to that species only?
Relevant answer
ugh ugh. In primates, this is a dull exhalation of air.
Studying the facial expressions of the eyes, we distinguished two elements - the animal is friendly or aggressive. For example, a gaze is aggression, a neutral, sliding gaze is friendly, facial expressions of eyebrows - flash (raised eyebrows) - are also aggression.
Sometimes they resemble a clear, articulatory pronunciation of vowels. Like "e", "o", "y". For example, lapunder macaques say something like "uh-uh",
For example, gaze - "I see", gaze and flash (raised eyebrows) - "I see" (menacing), gaze + flash + grin + body leaned forward + hit on the substrate - that's it, patience ends. With the addition of each element, the aggressive glow also increases.

Children with ASD need a clear and effective way to communicate to reduce frustration and
replace challenging or unacceptable behaviours (Beukelman and Mirenda, 1998; Webb, 2000).
Augmentative and alternative communication (AAC) interventions for these children have traditionally focused on unaided communication (i.e. signs and gestures). Subsequently, the focus shifted to aided communication systems utilizing the visual–spatial processing strengths of individuals with ASD (Light, Roberts, Dimarco, and Greiner, 1998). The PECS is an aided, picturebased communication system, aiming to develop the social exchange underlying all communicative acts.
Relevant answer
Answer
The Picture Exchange Communication System (PECS) is an evidence based alternative communication system for individuals with deficits in vocal language. It can be used to teach a variety of skills such as requesting, labeling, commenting, and answering some questions. How it is used depends on the client it is being used with. It can help reduce problematic behaviors when children are given a functional way to make requests for their wants and needs and can use PECS instead of problem behavior to do so.
Here are some articles on PECS:
Bondy, A. S., & Frost, L. A. (1994). The picture exchange communication system. Focus on autistic behavior, 9(3), 1-19
Charlop‐Christy, M. H., Carpenter, M., Le, L., LeBlanc, L. A., & Kellet, K. (2002).

As acclaimed by the researchers on religions; most of the religions talks on to the adherence to the commonly shared/cherished fundamental values, that encourage and reflects on gestures, man to man contacts, respectful interactions, honesty, and sincere understanding related to several issues, duties, and responsibilities encountered by mankind on a day to day engagements with other people through actions, interactions, and reactions. I understand, globally a whole lot of funds are invested to promote religious teaching to generate and enhance value based communication between groups of people. What I presume, if, is correct, then this factor should be considered playing a participatory role in the success of economic development. I would recommend researchers to initiate a fact-finding study on this issue.
Relevant answer

Soft skills comprise communication skills, interpersonal skills, listening skills, empathy and time management. A religious studies education empowers individuals and prepares them to deal with complexity, diversity, and change. It provides a wide-ranging knowledge of the vast world (e.g., science, culture, and society). Religious studies help a student to develop a sense of social responsibility. The student gains strong intellectual and practical skills such as communication, analytical, and problem-solving skills. The student acquires the ability to apply knowledge and skills in real-world settings.
Religious studies can help a person/student to gain the following skills:
  • make him/her capable of asking and answering complicated questions through the use of sophisticated research techniques
  • he/she gets the ability to organize and critically analyze various types of information drawn from a wide array of sources
  • he/she can consider multiple interpretations and varying narrative perspectives
  • he/she becomes able to produce high-quality written reports of his/her findings and interpretations
  • he/she can orally report and discuss results.

I am testing several methods for finding region of interest in hand gesture. in opencv for example I found some methods like camshift (for tracking a interest object), some background extraction methods (MoG, MoG2, ..) which specially are used in video to subtract background from foreground, which can also be used when we have hand as an object in a video with a complex background. and also GrabCut and backproject methods which can be used for hands posture in a static state. Contours, edge detection or skin methods are some other approaches for detecting hand in an image or video. And lastly I found that haar cascade can be used as well. I want to know that for passing from this stage, which algorithm is the best choice, considering that I use images with complex background. some algorithms like Grabcut or backproject were good but the most important problem was that I should manually specify some regions as foreground or background and this is not what it should be. After choosing a method for roi, generally what are the most important features in hand gesture recognition? for extracting features which method is your suggestion? that can work well with one of the general classifiers like svm, knn, etc to classify an specified image.

We witness that the religious denominations took into consideration changes without precedent in their dogmatic history in regard to the actual threat of Coronavirus. While spreading wide-world COVID19 makes changes in many social departments of our society on levels we never thought about. We see for example the RomanCatholic Church that suspended all masses here and there https://qz.com/1808390/religion-is-at-the-heart-of-koreas-coronavirus-outbreak/, banns the crucial gestures in rituals [ https://abc13.com/5976098/ to suspend the distribution of Holy Communion from the Chalice, to distribute the Eucharist preferably into the hands of the faithful, and to avoid the physical contact from a peaceful handshake, to forego ash crosses on forehead, to suspend placing water in holy water fonts at the entrance of churches, that the churchgoers “refrain” from kissing or touching the cross for veneration, or even cancellation of masses ] Buddhist temples and Protestant churches around Korea have also suspended religious gatherings. Orthodox Romanian Church did the same thing https://basilica.ro/patriarhia-romana-masuri-sanitare-si-spirituale-in-timp-de-epidemie/, but only in the first place, because after 'recommending' for its believers not to kiss public icons in Churches, but their indoor ones, and receive Holy Communion with teaspoons for single-use, same Church reconsider these recommendations and withdrew her decision [perhaps at the pressure of civil fundamentalists].
How can we qualify these measures and moreover the withdrawal on behalf of religious believers, as weakness, populism, diligence, assuming the human limits, or...something else?

Estimado Cosmin, te contesto desde las medidas que se han tomado para los católicos en toda España. Comulgar en la mano (algo que se hace desde siempre, pues es muy difícil que el sacerdote ofrezca el vino), que los sacerdotes y diáconos se laven bien las manos para dar la comunión. En este sentido nada se pierde del rito y del dogma de fe de comulgar con el Cuerpo de Cristo. En el caso de rituales menores, el de purificación con el agua bendita de la pila de la entrada no es obligatorio, hay iglesias que tienen agua bendita y otras no (se ha retirado el agua y no pasa nada) y respecto al gesto de la paz, en vez de estrechar las manos se acepta el saludo con una inclinación de la cabeza.

I have this project where i need to use social signal processing techniques in order to automatically detect mimicking behavior (e.g. gestures, vocal pitch or facial expressions) between a pitcher (i.e., an entrepreneur) and a panel of investors.
Research suggests that behavioral cues such as an open posture, mimicry and frequent eye contact can positively influence the perceived degree of coachability of an entrepreneur. Moreover, mimicry –which is the imitation of someone's behavior– is typically associated with affiliation and liking. For the aforementioned reasons a positive correlation between mimicking behavior and entrepreneurial success (i.e. the decision to invest) is expected

I have earlier worked on detecting hand motion gesture using Ultrasonic sensors. Sound is absorbed by different objects. But is it possible to quantify absorption and determine the type of deflector?
Relevant answer
Answer
Yes, it is definitely possible to detect the object. Generally, spherical object produces relatively smaller amount of reflect ultrasound. Remember the basic rule that the size of the object should be larger than wavelength. The detection capability basically depends on the sensitivity of the receiver, the frequency used. The motion of the object depends on the scanning rate and the software capabilities. For more details please explain the exact situation

Yule (2010) assumes that animals use systems of communication that are substantially different from human language. For instance, unlike human language, animals use linguistic systems that relate to the immediate time and place of communication. Also, animals are said to use “fixed and limited sets of vocal or gestural forms” (p. 13). Evidence from religious sources (Holy Quran) suggests that animals can competently communicate with human beings in systems that are both complex and productive. It is legitimate to ask therefore: Is it possible to integrate religious evidence into the linguistic theory to account for animal language?

Physically, is it possible the form of those human corpses could be preserved for 18 centuries (it was discovered in 1863) below 15m of ashes and volcanic rocks?

How could Guiseppe Fiorelli, the numismatist, could spot those "cavities" under 15m of ashes? See that scholar drawing explaining its "marvellous" discovery.

Yes, precisely. Some things are not in the usual place (for example teeth in the stomach), that let think those "bodies" (done in the 19th century), if they ever exist, were manipulated some way. On another hand, my question was wondering how this miracle of preservation of the bodies forms for 18 centuries, below 15m of volcanic eruption could physically happen? Because, for what I know, there's no other volcano in the world where bodies or whatever was preserved. So what? Pompeians were a superior kind of beings, heat-resistant ? Because they were from Roman upper class? I'm sure if you give them a Carbone 14 test, it will reveal the truth: they are from the 19th Century...

Many thanks
Relevant answer
Answer
Dear Luisa
In the course of conducting farmer interviews there are some key issues were repeatedly encountered. They do not cover every situation that farmer interviewers might find themselves in; but they are important to think about and prepare for.
1- Fitting in as a good guest:
Some of the challenge is also to become aware of the acceptable codes of behavior—the communicated and non-communicated house rules—and to avoid violating them. Being invited into a person's house as a social researcher is more than a simple invitation into their house, because when combined with an interview it becomes an opportunity to understand the interviewee's world.
2- Farmers decide who are "insiders" or "outsiders":
It might be best to cast notions of commonality aside and approach what the farmer says by thinking about why they have answered in the way that they have. Researchers might try to place themselves in the farmer's position and imagine what they would say if they were faced with the same complex, competing demands that the farmer experiences
3- Role of rapport:
When commonality between the researcher and participant does not exist, rapport becomes more important because it reduces the distance between interviewer and interviewee, reduces interviewee anxiety, and builds trust to make them more comfortable in sharing information.
4- Reflection as part of interviewing:
The conclusion of the face-to-face component of the interviews is only the completion of the data gathering and ideally needs to be followed by a period of critical reflection. This is because the research results are derived from more than just the analysis of the interview transcripts, but also include the reflection that happens after (and even during) the interview. The post-interview review and reflection is useful, because it is at this time that the memories of the key points of the interview are at their strongest. Critical reflection is, however, much more than just thinking about what happened, it is a structured process of looking at the topic from different perspectives.
5- A chance for farmers to construct their own identity
The key point is that when farmers participate in the interviews they do not agree to participate in any particular way; but are doing it on their own unarticulated terms and for their own reasons, which may include constructing a "self.
6- The unequal sharing of benefits from the interview
Interviewees can also find the experience rewarding because they are unlikely to often have the experience of another person spending an hour or so with them, and only being interested in them and seeking to understand their experiences of a particular topic. What initially appears as an unequal transaction—where the interviewer appears to make all the demands and receive all the benefits—may also provide some benefit to the interviewee.

I am trying to teach children to recognise people's emotions from body language/gestures as well as facial expressions. However whilst there is plenty of information available which describes facial expressions for emotions I'm struggling to find any information which links specific body language or gestures to certain emotions. I'm aware this is probably because there is far more cultural variation for body language than facial expression but I'm sure there must be some research out there somewhere, so hoping someone may be able to give me a good starting point please.
Relevant answer
Answer
Hello,
It seems that the majority of works on this subject involved actor, dancer or deal with the decoding of body posture/gesture (which emotion is inferred when the subject see someone and not which posture/gesture is the most correlated with the emotion induced).
More specifically, for the gesture, it's not certain type of gesture that seems to be correlated with basic emotion but more general parameters like amplitude of the gesture, rythmes and tensions (e.g. fist formation associated with anger). This point,you will find references on the link above.

How to coreograph dances from gesture corporals?
Relevant answer
Answer
Often called dance composition, choreography is the act of designing dance. From the semiotics perspective we can discuss the ways of choreographic significations. An appropriate approach can come from the area of social semiotics and multimodality (kinesic figures, postural configurations and categories as semiotic resources). The body can be regarded as a „expressive space” through which the individual can build cultural representations of social experiences.
You can also refer to The Philosophy of Dance in Stanford Encyclopedia of Philosophy. There you can find the following references:
For an anthropological and semiotic approach to dance see Hanna 1987. For a phenomenological approach to dance see Albright 2011. For a phenomenological approach to dance, movement and thought that makes recourse to evolutionary biology see Sheets-Johnstone, 1981 and 1984. For a process philosophy approach to dance see Manning 2013. For more on the relation between philosophy and dance see Foster, Rothfield and Dunagan 2005, Sparshott 2004, and Van Camp 2009.

We are doing research about a gesture system called Visual Phonics.  The hand shapes, corresponding to sounds, can be useful in literacy instruction with young children, both with and without disabilities.  The individual hand shapes are fairly abstract initially, but, with repetition, do take on meaning.  Does this indicate a shift from one type of gesture to another?
Relevant answer
Answer
No. Iconic symbols must be perceptually similar to their targets (possibly in a broad way) and presumably at least partly understandable out of context. When an abstract symbol takes on a conventionalised meaning it does not change its nature.

I am currently working on how body-based resources such as gestures, especially deictic (pointing) by teachers have an impact on young children arithmetical development.
The attached journal seems to be a very good journal on gestures
Embodiment in Mathematics teaching and learning: Evidence from Learners' and teachers' gestures.(2012)  by Alibali and Nathan . The Journal of learning sciences
Good luck.
Best

I'm looking for a good open-source gesture recognizer (in particular, pointing gesture) that would work on Linux. Either using skeleton tracking (OpenNI) or other RGB-D methods.
While the theory is rather simple (typically, you want to train a hidden Markov model), I'm looking for an robust implementation + trained model.

Hi,
maybe have a look at the Vitruvius project: https://github.com/LightBuzz/Vitruvius. It uses Kinect and Windows, but based on the code you can easily create your own gestures and the recognizer.

It is well known, that co-expressive gesticulation gestures develop their structure of movement accompanying the verbal and melodic structure of the utterance and also that they are linked to it semantically and pragmatically.
When analysing gesticulation gestures linked to verbal language and intonation, it seems to me a little bit difficult to establish a close descriptive relation between the movement structure of gesticulation gestures and the verbal and melodic structure of the utterance in spontaneous speech.
I think, that one of these categories or aspects has to do with the close relation between the more prominent segment in pitch range of the utterance and the more prominent phase in gesticulation structure.
Could you suggest me other categories or aspects I should pay attention?

Answer
Dear José,
As you know, Núria Esteve-Gibert recently discussed her PhD thesis exactly on the alignment between gesture, prosody and segmental material. Since the research question of "gesture-prosody-text alignament" is actually not new (dating back to even before McNeill's 1992 book), Nuria's thesis focussed on some more specific and new issues, that had to do mainly with language adquisition and infants. In case you are interested in the alignmanet/interplay among gesture, prosody and segmental material in adults, you might have a look at the Introduction of Nuria's thesis, where she summarizes in a few pages the most relevant studies about this subject.
See you in June :-)

In a cambridge hand gesture dataset, I am getting 100% accuracy using 10 fold cross validation? How should I confirm whether this prediction accuracy is correct?
Relevant answer
Answer
100% accuracy on cross validation is very strange. Try reducing the folds to see if the accuracy changes to ensure that there is no programming error. Especially while calculating accuracy. However if the accuracy is on the training set then its overfitting. Just curious- are you using decision tree?

I have tried classification of static hand gesture using hue moments and the accuracy using this feature is very low. I am using SVM for classification.
Relevant answer
Answer
The relevance of  moment (Hue and others)  is related to the features on which they are estimated (edges, regions...). We used moments and size functions (critical points).

Leap motion controller only tracks finger/hand gestures (If I'm right). I need to track the motion of reference objects, such as dollies stuck to deforming objects, which is out of the tracking scope of sensors in the class of leap motion controller. Optotrack technology can definitely do this stuff perfectly, but at a huge financial investment. But what I need is a very affordable trick in the cost range of leap motion sensor (or a way to make leap motion sensor track a 'non-finger' object) at a similar resolution.
Thanks a lot.
Relevant answer
Answer
Hello Saeed,
I have had some bad experience when tracking objects with low-cost material like the Kinect or the Wiimote: the field of view is limited as well as the sampling rate...
But this may change with the Kinect 2. The advantage is that you can interact with a big community who might help you in finding optimal solutions for your problem.
Ok hope this helps

In this paper, it seems that the only kind of ambiguity permitted is in the bindings of variables (and it's not clear to me how competing candidate bindings are maintained through a parse after being detected). How is structural ambiguity handled; for example, when a gesture might be either "identifying" or "visualizing"? There would be multiple competing parse trees for as long as the ambiguity persists in the discourse, and thus the "right frontier" could have several competing candidate constituents at each of its nodes.

We can apply the principles of Eisenstein's relativity. A chronicker delta will give either one or zero when the possibilities are either Yes or No and the metric tensor will solve all potential possibilities more than two.

when using a skin detection algorithm, i need to take the hand as an object, but this algorithm detects the face too, so i need a heuristic more powerful than taking the biggest contour so i need your suggestions please.

Answer
What is your sensor setup? 2D Color cam or 3D sensor like Kinect? Using the Kinect and the skeleton tracking, it's much easier to find the hands in the image.
If you have a 2D Image sequence, you could use optical flow to distinguish between hands and head in case the heads move faster.

The background subtraction is achieved by running average method which con-
tinuously updates the background model. Hence if the hand is still for long
enough it is considered as the background and the gesture is not detected.

Hello,
It is good if u could extract motion features to represent hand gestures. Motion features could be used to represent dynamic gestures.

The goal of my study is to prove behavioral differences between therapists in CBT with ADHD patients, that might influence the effectiveness of the treatment.
The focus of this analysis might be on empathy of the therapist, using certain techniques (e.g. frequency of paraphrasing), showing interest and commitment, body posture and gestures (certain movements), the way in which the therapist structures the session, etc.
Relevant answer
Answer
Sounds like this is for research (maybe a 'dismantling study,' and not for supervisor feedback?). Agree with Mr. Girard, CSPRS looks useful. It may also be useful just to find previous studies with similar designs and grab their methods for comparability/replication etc. All in all, that is probably the approach with the least stress and most straightforward scientific contribution (though I would recommend analyzing in a way that avoids the pitfalls of most psychology measurements - more in the rant below).
Ideas:
Fidelity scales are always useful if you have a particular model in mind. E.g,. Cognitive Therapy Rating Scale (CTRS; Young & Beck, 1980). Also, several things you mentioned are pretty well conceptualized in Motivational Interviewing fidelity scales (I think Moyers et al., 2005 "MITI" is standard, review here: http://www.sciencedirect.com/science/article/pii/S0740547206000894). Whatever you use, you will probably find that some items are not necessarily applicable and some will seem impossible to rate in your specific context. This in itself is valuable scientific information, albeit more qualitative (though not empirically untestable...).
Psychometrics rant:
Would also look closely at previous evidence of inter-rater reliability (for obvious reasons) and at the intended factor model, and both should be examined in your sample - hopefully establishing interrater up front.
Concerning the factor model, one wouldn't expect therapeutic process factors to be uncorrelated, but with previous technology (and a lot of remaining habits in psychology) exploratory ("empirical") orthogonal models such as PCA are applied that maximize independent variance but poorly reflect the way we think about what's being measured. Differences across studies are also difficult to interpret due to the arbitrary nature of non-hypothesis-driven component derivation (e.g., the factors in Hill, O'Grady, and Elkin being different from a previous study). Whether you decide to use another study's method directly for the sake of replication or if you pick and choose from other areas to assess the factors you're hypothesizing, you as the researcher should decide what you're trying to measure (and ideally test those assumptions, e.g., with confirmatory factor analysis). Using summed scores is also a problem, but that has been addressed abundantly elsewhere (e.g., http://pareonline.net/getvn.asp?v=14&n=20).

The book "Body Language" written by Allan Pease is very widespread, but I have never seen any studies which tested explicit/implicit influence on people's perception of each other if they use gestures/postures from that repertoire. Maybe you have?
Relevant answer
Answer
Pease's book is popular and based on rather old findings and anecdotal evidence. If you are looking for accesible introduction to the topic I recommend Patterson's book "More than words". You can find there many practical information based on experimental data.

Hand gesture detection sensors , such as Microsoft Kinect, are soon going to be a part of the operating rooms to enable surgeons scroll through and modify medical images during surgery. This will help them to access images and files faster without compromising sterile procedures. 
Relevant answer
Answer
first of all thank you very for excellent question in the discussion,
According to my opinion the use of gesture detection sensors in healthcare is good idea and practices. However, this is a new technology therefore it required some time to build in practices and also it required some good level of expertise.
According to my second suggestion, as we know Microsoft Kinect mainly build for gaming propose, however the use of Kinect can be much useful in stroke rehabilitation via gaming. Using the kinect game we can able to provide natural user interface in which results the patients can engage, motivate and can learn more, as compare to traditional stroke therapy.    
However, the use of Kinect in healthcare required safety i.e. during the patient play, patient should not play fast  and not to take much stress otherwise it can be more serious.

I am working on a project about hand gesture recognition/tracking, I don't know if you are familiar with sixth sense technology. I want to do some implementation for hand gesturing that is used in this technology. An inventor of this technology is Pranav Mistry,
The signals are gestures, images, video streams. the camera captures the image and then sends to a smart phone. Smart phone do processing and then sends information to projector. projector projects image on the mirror and finally mirror reflects the image on the wall or object on view-object. Can anyone suggest technically detailed information about hand gesturing techniques used in gestural recognition technology?
