Hi everyone,
ICU nursing staffing's impact on patient (and other) outcomes is well documented in the literature. Nonetheless, methods (e.g. Nursing activities score) have been criticized during the last decade for not including several aspects of the nurse's work besides bedside duties.
Currently, which would be the most valid approach /tool to objectively estimate nursing staffing?
Relevant answer
Answer
Cristobal,
it depends on what you are most interested in. There are scores and ways for assessing workload in bedside nursing that accounts for physical and cognitive workload. Look at work by Heather Tubbs-Cooley. Also, make sure you are looking at the right measures. As I’m sure you know, tools to assess staffing models are not the same as nursing workload. I have partnered with nurse scientists at Emory to look at a combination of metrics, but it also depends on the question you are asking. Hope this helps. Feel free to DM me if you want to discuss further

Dear all,
I collected the data from 14 participants by using an item-Likert scale (1-5) related to workload measurement. The same participants rated the scale for six different-sized keyboard designs by considering workload. To understand if there is a significant difference among the six keyboard designs, I applied the non-parametric Friedman test. I found a statistical difference, so I applied Wilcoxon signed-rank test with Bonferroni correction for pairwise comparisons.
My question: While I found no significant difference between LL-SS, there is a significant difference between ML-SS, though LL and ML have the same mean. Is this true? adjusted alpha value = 0,05 / 15 = 0,00333, the Wilcoxon result is 0,00306 for ML-SS. So I considered it a significant difference. Did I make it correct?
Looking forward to your support!
I attached the workload results and spss outcome.

Answer
Hi, Emmanuel Gabreyohannes . In general the signed-rank test isn't a test of medians. It's pretty easy to come up with an example of observations that have the same medians, but will result in a low p-value for this test. ... As a side note, technically the test can't be used with strictly ordinal data as the first step is subtracting paired values, which wouldn't make sense for strictly ordinal data.

I am looking anew into the area of what used to be called "scalable autonomy." I worked in this space briefly around 2014. Now, though, I haven't been able to find much associated with the terms "scalable autonomy."
I am wondering how researcher are now referring to the scaling of autonomous support from AI to a human user based on things like human-cognitive workload (AI's engagement increases as human's cognitive workload becomes saturated) or impact of contribution (AI engages when its capability is most relevant to the problem at hand such as a navigation system engaging when a new destination is desired). Any recommended references would be greatly appreciated. Thanks in advance!

I want to research abaout the physical workload for electri worker. Iwant to find any suitable methods.
Relevant answer
Answer
On many occasions, physical fatigue is associated with the maintenance of a forced posture. Methods for evaluating physical workload taking posture into account include:
• OWAS.
• RULA.
• REBA
Cargo handling also causes overexertion. NIOSH equation can be helpful in evaluating lifting loads.
Measuring energy expenditure during the work period is a criterion that, when compared with the worker's physical work capacity, allows evaluating his aptitude for the type of work he performs and being able to establish adequate work and rest regimes. To measure energy expenditure, several methods can be used, among which are:
• Direct measurement.
• Indirect measurement.
• Estimation from tables of standard values.
• Estimate according to profession.

I hear from many senior doctors- more than 20 - 25 years of experience- in residency training clinics and departments that a new generation of assistant doctors are on the rise.
Of course the generations change, and this is normal, but there could be interesting opinions.
Would you like to share?
  • Have you realized behavioral patterns different from "the old times"?
  • Have the expectations/stress responses/ increased work handling of assistant doctors changed recently?
  • Is there a noticeable difference in the way the new doctors treat each other in their daily routines? Are the clinics more or less stressful nowadays?
  • How about medical students?
Relevant answer
Answer
I am not an expert in the medical field. However, if you are referring to the workload, it depends on the organizational plan. Usually, organizations have already assigned the worker according to the schedule in one period, determining the number of people with a specific skill in a specific job. But this is not for the emergency. If management thinks the plan is working well (no customer complaint, no rework, no queueing, etc.), the workload will not be considered an issue.
So, in my opinion, organizations have to change themselves first before the employee.

Question

I am currently working on a research about teachers' motivation, workload and stress appraisal. I have 345 respondents. One of my research questions is:
How do teachers perceive their assigned workload? (The purpose of this question is to determine if teachers are experiencing overwhelming works or assignment in their workload)
The instrument is a likert scale wherein you are just going to sum the responses of every item to generate an overall workload perception of the teachers. The higher the score (50) means they perceive that their workload is overwhleming while the lower the score (10) means they do not perceive an overhwelming works or assignment in their workload.
My null hypothesis is:
Teachers do not perceive overwhelming works in their workload.
I'm actually confused right now. Is it necessary for me to use a statistical test to test my hypothesis?
or
Can I just do simple analysis where I get the percentage of how many teachers get a high score in the instrument for me to decide whether to accept or reject my hypothesis?
Thank you very much!
Relevant answer
I would suggest a linear regression analysis so that you can see how much of the variance in stress level is explained by teachers' perception of having an overwhelming workload. You can group the participants in 3 groups in the way Ziga Kozinc suggests. You use stress level as DV (dependent variable) and the 3 groups as IV (independent variables) in the regression analysis.

Measuring driver workload subjectively is a useful way of further understanding the effects of (for example) changing environmental conditions throughout a journey. In a driving simulator study where a participants shall experience multiple 'interventions' within the same homogeneous driving scenario it would be useful to gain a quick understanding of perceived workload for each intervention. For example, drive for 5 minutes under condition X, measure workload for condition X, continue to drive into condition Y, measure workload for condition Y ... etc...
Methods such as a Driver Activity Load Index (DALI) are very useful when participants have time to stop a scenario and engage with this pen-and-paper method directly after each intervention. However, when running multiple interventions back-to-back are there any recommended metrics (non physiology-based) through which one can measure perceived workload through verbal questioning/answering in a time-efficient manner?

As an author and a member of editorial boards of some scientific journals, I have observed the growing concern on the delay in manuscript review due the difficulty in finding suitable and willing reviewers. Publishing manuscripts/papers in reputable scientific journals takes an average of one calendar year. It could be higher in some well sought-after journals. It is noted that about 65-70 % of the time is spent getting the paper reviewed. Many of our colleaqgues are not willing to accept review request due to high workload while some who are willing may delay the review beyond tolerable time.
Also, there is geometric increase in the number of Journals with disproportionate increase in researchers willing to review manuscripts. The known and outstanding researchers/reviewers are over-requested or oversubscribed, while the green horn are seen to be inexperienced and not invited to review. Therefore, there is need to increase the number of reviewers, but how ....? Also, there is need to encourage researchers & academic professionals to accept review request and complete review within reasonable and acceptable time frame.
I am currently working on a review paper on how and ways to encourage timely review of manuscripts and how to reward manuscript reviewers.

I am a master's student in organisational psychology. My dissertation is a systematic review of the measures of workload in air traffic control. This will be a narrative analysis of the findings and implications. Workload in air traffic control is tested under many heterogeneous conditions, which authors have commented prevents from doing a meta-analysis. My analysis will focus on which types of measures (self-assessment, eye movement, EEG, heart rate) have successfully discriminated levels of workload, commenting on the design, methodology and participants in the study, which are often different. Is it possible to borrow elements of meta-synthesis to achieve a structured and comprehensive level of analysis? Thank you!
Relevant answer
Answer
I think reasons not to do a meta-analysis revolve around intolerable differences between studies. Ones that may be mentioned in the literature of your field and proved to make a difference in the outcome. For example, in clinical research different doses of a drug can be a problem, specially if the difference was established in published articles.
To manage these discrepancies, you can do a "subgroup analysis" which makes a separate MA for each set of circumstances and compare each group with certain differences. Or you can do a sensitivity analysis, which involves removing studies that are substantially different (by some defined factor) and see whether removing them makes changes on the pooled estimate. However, it doesn't completely solve the problem, sometimes it's just not a good idea to compare studies using a meta-analysis. If so, try to report results of studies narratively, many systematic reviews are published without MAs. Good luck!

I am perplexed by a use of ARIMA seen in a paper in the literature.
For a time interval T1, a periodic workload was generated for virtual machines.
For a training time interval T1, data was gathered about resource usage and power consumption. It is not stated whether any migration took place. This data was used to construct an ARIMA model.
For a (subsequent) testing time interval T2, the ARIMA model was put to use to predict resource usage and power consumption.
However, during T2, a migration was forced. Can an ARIMA model predict about an event unless it took place during the training interval T1?
Relevant answer
Answer
Franco Davoli Unfortunately, the authors do not provide any detail about the construction of the ARIMA model. At least, I was unable to find any, even when I looked up earlier works that they referred to with regard to the ARIMA model. To answer your question directly, the best I can state is that they claim that their "historical data" allows them to predict the power consumption after a VM migration has taken place, both for the source and for the destination host.
They do emphasise that they use "static and periodic" workload patterns to accumulate the historical data but I find no reference to whether they use migrations in these workload patterns.
What bothers me most is that the predictions of host power consumption which they show, includes prediction (of the host's power consumption) even during the VM migration. I would dare say that unless migrations are also part of the periodic pattern, then it is not possible to make predictions on the ARIMA basis about host power consumption during a VM migration.

For obtaining the acute-chronic workload ratio and make a comparison with the injury rate in a basketball season, i wonder which variable is better to measure for obtaining the data.
Relevant answer
Answer
Usually, the most reliable method for measuring acute chronic workload ration (A/C) is employing a repeated-measured days for an extended period of time, let's say 28 days. You would use the data to compute the load accumulated during the current week / load accumulated weekly over the past 28 days, by considering the internal variables and external variables. In regards to which external parameters to use will depend on your study, using tracking variables, often GPS-related, such as high-speed running and acceleration variables are all plausible options. Do consider the locomotor disadvantages in measuring A/C, thus considering maybe using various tracking devices or even the session-RPE method.
Hope this helps!

I'm asking this because every individual perceives task demand differently. Hence, a varying task difficulty for the different levels of demand. But, Is there any valid relationship between task demand and changes to pupil diameter.
From a few driving simulator experiments, I found that the workload obtained from the NASA-TLX and that obtained through TEPR (eye tracker) are not similar. It is almost as if the NASA-TLX and eye tracker follow a different approach in measuring workload (one focuses on demand/difficulty (subjective to participant interpretation) and the other on difficulty solely (eye tracker)). Am I missing something crucial about these measures of Workload?
Thank you for any guidance on this.
Relevant answer
Answer
Estimates in workload taken from eye-tracking measures (blink rate, pupil dilation) might differ from subjective ratings for a number of reasons.
One may be that the task is highly visually demanding but not particularly cognitively demanding or vice versa. Were there any other demands on participants which may have resulted in these measures being different? Were the lighting conditions similar between conditions? For example, were participants driving in different scenarios (night and day?).
If you suspect it might be lighting conditions, you may want to read.
A paper you should definitely read is Recarte 2008, which is an older paper, but highly cited in these types of discussions.
It's also discussed in this paper.

Answer
I assume that you used XRD for this study. In a XRD diffractogram, a left-hand side peak corresponds to greater d-spacing than a right-hand side peak. Therefore, you were expecting wrong for the peak to move right if you were to observe increased d-spacing. In this case, you would observe the diffractogram peak to move towards the left side to see increased d-spacing.

It has been a policy of many so called "reputable" journals to give Editors mandate for upfront or desk rejections of submitted papers with a claim of minimizing the workload fort their reviewers and decision times for manuscripts (which can be attended accordingly) that are (in qualified Editors perception) found unsuitable. Since reviewers are critical in evaluating manuscript's contributions soundness, it can be observed that Editors only find something to do for their mutual existence.
On the other hand, this gives room to predatory journals that invariably offers fast publication processes that could easily compromise any existed sound contribution conclusions and research directions.
Relevant answer
Answer
I've been desk rejected twice, once was justified, and another was not. The case that was justified was because the editor felt that the paper wasn't of much interest to an international audience as my paper was regional in theme. I can live with that one. The unjustified one was a case where the editor was actually honest in his poor ethics. He said he would not send it out for review because it was too similar to paper that his team was about to publish in his journal.

I've sketched the following basic metrics categories that one can get from a cloud-native application monitoring solution and use for e.g. anomaly detection:
  • structural (e.g. length of a request trace)
  • temporal (e.g. traces as distributed on the timescale, duration of the trace and calls within it)
  • performance (e.g. 99%-tile response time, throughput)
  • resource (e.g. CPU utilization, memory utilization)
  • workload (e.g. request rate by endpoint)
  • capacity (e.g. number of pods for service)
What do you think about it? Is there something missing? Can some more coarse-granular grouping be introduced?
Relevant answer
Answer
I agree. This matter may be considered in the broader context of Control Room based Network or System supervision. This applies to transport networks (Deutsche Bahn as a main railway operator in Europe supervises rails and trains) in electricity (production or electricity transport or distribution operators on their infrastructure), telecom (AT&T supervises its networks and services).
In all these cases you have:
-service layer
-asset layer (assets using infrastructure underneath)
-infrastructure layer
-physical system assets composing the infrastructure.
For each layer you have parameters monitored and alarms.
If you want to go deeper look for ETSI-ISG-NFV, this is about network function virtualisation, and going back and forth from real systems to logical representations

Some workloads or even inputs perform well on GPUs, while others perform well on multicores. How do we decide which machine to buy for a generic problem base for optimal performance? Cost is NOT taken as a factor here.
Relevant answer
Answer
Dear Ahmad,
Besides cost, there are many factors you have to consider.
First, you are asking which hardware to use for a given algorithm or implementation, which I think is not the right question because a parallel algorithm is developed taking into consideration the hardware.
I'm not going to take the same approach if my solution is for a cluster using MPI, a multicore processor using OpenMP, or a manycore processor using CUDA.
So, before deciding the hardware and the algorithm you have to analyze the problem (you may be interested in looking for Foster's methodology). How can it be decomposed (many independent tasks, few coarse grain tasks, etc)? Is it regular (in its memory access pattern, in the operations done on data)? What's the size of the data (can it be fitted in a GPU memory or in the main memory)? Is it memory bound or computation intensive?
After this process, you can take the decision about the hardware and after that you can start developing the program.
Finally, when you have a functional program, you should start with a performance tuning process for maximizing the performance indexes of your interest (speedup, efficiency, power consumption, throughput, etc.).
Best!

In the model in my thesis, I draw a direct link between the two constructs organizational constraints and workload to the construct Abusive Supervision. Studies have shown that constraints and workload are stressors and negatively impact performance, motivation and well-being. I justify an increase in Abusive Supervision that way, that there were studies that have shown that supervisors e.g. treat the employees hostilely, because they perform poorly and thus throw a bad light on the supervisor. Can I put my questionnaire under these assumptions? And just assume from previous works, without interrogating the performance separately, that the two stressors have a negative impact on performance and thus favor hostile supervisor behaviour?
Like this: Organisational Constraints ++----> Abusive Supervision
Or do i Need to put it this way: Organisational Constraints- - ----> Perfomance ++-----> Abusive Supervision
I hope my Question is understandable. Thanks in Advance!
Best Regards
Kim
Relevant answer
Answer
You can develop your questionnaire, based on these assumptions, and then use the results to possibly falsify those assumptions, which would be great, as that's the goal of science anyway. But you need to word the questionnaire in a way that does not produce a bias towards or away from your assumption.
Is our questionnaire going to be a large scale survey or an interview? If it's an interview especially, you're going to want the questions to be open ended so as not the lead the interviewee. So you wouldn't want a question like "do you agree that when your work is of poor quality, your supervisor acts abusively?" And instead perhaps ask "how does your supervisor respond to the quality of your work?"

  4. Statistical
  5. Inductive
  6. Abductive
The system must also deal with missing premises on all of the above

I am looking to apply the method of Protest Event Analysis to my Masters dissertation on women's social movements and gender inequality. The literature I have looked at so far only mentions teams of researchers applying this method. Is it possible for a single researcher to use this, or is it near impossible due to the workload?
Relevant answer
Answer
Chara,
as posted above, a single researcher can. undertake PEA; however, the key, as I see it, is to create a manageable project; especially in your case, ask yourself if you can 'do' a PEA project----including a 28000 word dissertation-----for submission in May 2019.
Fieldwork with say a local women's movement will perhaps need institutional ethics approval.
Mostly or wholly deskwork?
I don't think that your choice of PEA is the problem; rather, your problem is putting together a project which can be 'done and dusted' in the time you have available.
You need a small project eliciting rich data---in which case, systematically writing-up each of its elements in 28000 words is, I think 'doable', a lot of work, but satisfying if you get your Masters.

Dear Fortunatti
Fernandes etal. 2010 mentioned that, In an ICU, nurses note daily whether critical patients will require prolonged assistance regarding the performance of routine procedures both upon admission and during their stay because organ instability can occur at any time over the course of the patients' stays in these units.
Panunto 2012 stated that Nursing workload consists of the time spent by nursing staff to perform the activities for which they are responsible, whether directly or indirectly related to patient care. These activities can change depending on the patient's degree of dependency, the complexity of the disease, the characteristics of the institution, work processes, the physical layout and the nature of the professional team.

Answer
Hi Tanvir
Do remember that all CPUs are not equal. Also bear in mind that in the process of virtualising a CPU, there will be an element of overhead to take into account. A virtualised CPU will always be slower than the same CPU running in a non-cloud environment. And a more powerful CPU will always run faster than a less powerful one. I have attached a list of some papers on AWS performance. Of these no 1 on the list, Ou et al, in 2012 carried out an analysis of AWS cloud instances and found a large variance between resource performance. Here is the reference:
Z. Ou, H. Zhuang, J. K. Nurminen, A. Yla-Jaaski, and P. Hui, “Exploiting Hardware Heterogeneity within the Same Instance Type of Amazon EC2,” in Proceedings of the 4th USENIX conference on Hot Topics in Cloud Computing, 2012, pp. 4–8.

You must use the data and the time period axis for illustrating the linear/curve of the workload which you need. In this way, you can analyze the Alpha and Beta in relevant equation as Y=alpha+beta.X in which you can use the Growth for the variable "Y", and the Productivity for the variable "X" while the alpha is the "width of the source" and beta is the "tilt" of the curve. It is obviously specified that proper value for the alpha and beta should be positive.Therefore, in this way, you use the "BSC" method which is the development method in your evaluation.

Relevant answer
Answer
The limitations of the TISS-28 is it is based on how we provided critical care 20 years ago. A great deal of nursing care has changed since then that are not captured in the TISS-28. For example we keep patients more awake, promote more mobilization than before yet these items are not captured in the TISS-28.  I would argue, because it misses important advances in critical care, it has a tendency to underscore workload. 
Saying that, this tool does have a lot of validity and reliability evidence in ICUs around the world.

Carlos, 
According to some previous tests that we did in our laboratory, we guess that "Tlim" at VT2 should be around 20-25 minuts. It's true that the relative load is linked with the protocol used to establish the intensity, in the same way that "Tlim" at MLSS intensity depends on the protocol actually used. Considering that, there are several studies showing that MLSS and VT2 intensities are in fact diferent physiological facts, "Tlim" at both intensities vary greatly.
There are lot of research works testing tlim at diferent intensities in percentage terms (between 85 and 95% of VO2max), that can help you to guess the answer you are searching.
We did a work where analised "Tlim" at MLSS and just tested the tlim at VT2 in two different subjets (not published as I told you previously), so feel free to read it if you consider interesting to do it.

As an ergonomics practitioner, I have noticed that an issue often overlooked in line balancing is variation in performance by employees.  You can use standard work (predetermined time values) to balance the line and determined the theoretical bottleneck.  But when you actually get out on line and observe conditions throughout the day, you often see a build-up of work-in-process move to different points/stations in the line as employees rotate into different stations during the shift (say every hour, or rotate every 2 hrs).  This is often due to variation in productivity of individual workers from station to station.  I term this a variable bottleneck situation. So keep in mind that the reality of line balancing is broader than any specific theoretical model - due to human variation and individual differences.  And my opinion is that this station-to-station variation is often due to what I like to call "ergonomics mismatches".  This might be a shorter stature person working in a station where they must elevate their arms (resulting in discomfort or fatigue in shoulders), or another example is where an employee with limited hand strength works at a station requiring high hand forces.  In these situations, a line balancing model may break down.  So keep an eye out for ergonomics when balancing your line.
