Thank you! however it is not downloadable

BENEFITS:

You may avoid high tuition fees & other living expanses. You can live in your family house with your family. You can work full time & get experienced in job(s) & gain considerable income & also accumulate retirement pensions.

The question makes no sense, as the questionnaire can only be "validated" when the interviewee has completed it.

Also, I remind you that opinion polls leave the time they find.

Hello Dr Minakshi Rana

I have no experience with this specific journal but I note that there have been many threads about people waiting even longer!

Depending on your article topic, Brown Journal of Hospital Medicine also has fast review time. Even AAP's Pediatrics has quick review process.

Cureus is fastest in the process all over.

There is a range of software, depending on your discipline and the type of data you are collecting. Currently in social and beahvioural sciences, the preferred software packages are STATA and also R. However, SPSS is also a good package but expensive to purchase. R is free. Excel is also available as part of Microsoft Office but its statistical capability is not as good as some of the others.

If you are collecting qualitative data then packages can include Nvivo, Atlas, Maxqda, among other.

Hope this is helpful.

thanks for the great information. where does it take place?

Qualitative research emphasizes and develops a detailed understanding of participants’ experiences. It is unconcerned with sample representativeness; therefore, it does not apply a priori sample size estimation—as in quantitative inquiry. Instead, it employs non-probability sampling methods (e.g., convenience sampling, quota sampling, & snowball sampling). In other words, individuals are chosen for the sample because they can furnish elaborate inputs to address the questions under investigation. A common principle for determining the adequacy of qualitative data is saturation, which refers to the notion that additional data collection or analysis is unnecessary based on the data that has been already gathered or analyzed. The following can render germane guidance.

Good luck,

Just go for normal. The means and standard errors will be close.

Thank you dear Dr. Mônica Chaves for the inputs.

Resistant exercises can tire MS disease quickly. This is an undesirable situation in patients with MS.

I recommend more ROM exercises and short-term isometric exercises.

Hi Dr Avaniendra Chakravartty . Placing the wrong person in a particular position has a very bad impact on the performance of the institution in all respects. The most important thing in any institution is the top of the administrative hierarchy, so it must be competent and appropriate for the position, otherwise the results will be disastrous.

Without a conceptual framework that links a) core theories with b) key concepts and with c) all of your research questions / hypotheses in the study it's not sound research.

Many researchers / students avoid it, though, because it is a lot of work to develop a substantial and consistent conceptual framework.

You should definitely go for one in your research. Good luck!

BMR and BMI are different but are both important indicators of health especially in the days we are living of diseases of lifestyle.

Dear Nurfarhana Farah Abdullah and Ahmed Hassen ,

To answer the question, I think it is good to realise that there are basically two publishing models: subscription-based (most of the time free of charge for you but for readers the papers are behind a paywall) and open access (free for readers but most of the times they charge you as an author). The confusing thing is that more and more subscription-based journal are so-called hybrid journals. If you choose the open access option this is extremely expensive, however you are fully free not choosing this option. See for example: https://www.elsevier.com/journals/nonlinear-analysis-hybrid-systems/1751-570x/open-access-options

If you are (still) looking for free open access journals (with serious indexing like Scopus and/or SCIE index) you might have a look at: https://www.researchgate.net/post/Scientific_Journals_with_Open_Access_and_no_APC_free_charges_for_authors

For subscription-based journals (most of the time free of costs) you can check: https://www.scopus.com/sources.uri?zone=TopNavBar&origin=searchbasic for Scopus indexed journals. And for either ESCI or SCIE (SSCI) indexed journals you can check: https://mjl.clarivate.com/home

Good luck.

Best regards.

Interesting

Yes Rolando García-Martínez , is a very interesting area and we haven't much people studying it. Thank you for you contact.

Best regards,

Dear Dr.Lidia,

There are many online journals, such as American Journal of Infectious Diseases and Microbiology, American Journal of Public Health Research, Biomedical Research International, Journal of One Health etc, in which review articles can be published.I have published reviews in all these journals.

Stay safe and healthy.

With kind regards,

Prof.Dr.Mahendra Pal

Try to find source available on Cornell University website for protocol publication and registration. They have a lot of agencies that register and publish protocol.

Thanks

Thanks Hein for your comment.

It may be true that research money does not paid by local authority directly; however, in most cases research money comes from people tax money through government or companies's (extracted from local natural resources or local labor force). Therefore, research money is also local people's money directly and indirectly. On the other issue, research has NEVER been free from "the expectation". Most research always do have agendas/goals/exceptions, these exceptions may be directly or indirectly connected with institutional/academic/industries needs. So, research has never been truly “neutral", there are many done on this science false "neutrality" claim. False "neutrality" is also government or companies's exception.

However, my question was in different point in this post. As a researcher what are our responsibilities while we are doing research in community's natural resources, health, economy, and development? Whose observations give shape to our research questions and practices? Does the research fit with the priorities for research defined by community? Do we have the capacity to participate in our research? Does this research fit with community values? Is the researcher-community agreement fair in terms of benefit sharing, plans for conduct and dissemination, and all other elements of a rigorous community-based research agreement?

I know there are many research done in these challenges; however, the many communities are still facing many challenges from academic and non academic research, and many issues remain unsolved. Many communities are very fearful when they hear the term "research". It does not mean they do not want research, many communities have been using the term "research" from many generations; however, they have different meanings and purposes. As a western-trained researcher, are we failed to understand the community meanings of research that can be benefited for both (participants and research)?

Some core-attributes I miss today is the ability to listen, empathize and touch.

Listen and empathize are blocked by modern time-management and the ability of touching is rare tody in general, not only under physicians because of too much inhibiting Pictures in the mind. But all the three competences are essential abilities to become aware of what is with a person I maybe treat in a certain way...

Hello Sajeevanie,

Its a qualitative study. I tried Flesch Kincaid test to estimate the reading easiness. The core matrix what they use is word length and sentence length. But, for a profession specific text content, I thought Flesch Kincaid is not an appropriate option.

I include both sex and gender. It is important to acknowledge sense of self and biology as both contribute to how one interacts with their environment. As Ladan Rahbari stated it is important to provide as many options as possible including "other" or "prefer not to say". I think it is important to present all data collected for a study so long as their responses are complete. In this case I would present the data from the 20 participants who chose not to identify their sex or gender as a separate category. If these responses differ significantly from those who did identify it could make for an interesting discussion in any publication or presentation you disseminate. Discussion points could include confusion, shame or self-prejudice based on ones sex or gender identity that would cause someone to not want to divulge that information in a study.

Great answer Carl. Students' interest and students' perceptions take an important role in this topic.

I thought the official language of ResearchGate is English. I also thought this forum was not for looking for employment.

TQ very much Prof Gulzar Shah for your kind response. That was very helpful.

concordo, porem para desenvolver as habilidades socioafetivas é preciso falar das experiências e refletirmos juntos com alunos e profissionais caso contrario ficaremos teorizando enquanto o sofrimento psiquico vai se desenvolvendo e com ele estrategias defensivas que afastam o contato e inviabilizam o vinculo essencial para o cuidado humanizado...

Immersion learning is a critical concept that enabled me to look at teaching and learning in new ways. And,...since 1997, I have never looked back.

What will this be used for?

So, the real difference between the two types of research is what they will be used for. Will the research be used to help us understand a real world problem and solve it, or will the research further our general information?

Stata is preferred by our team. Once you learn the commands it is very powerful and a smooth user interface.

In environmental epidemiology, for example, estimates of effect typically refer to the relative or absolute risks of a given exposure in an observed population (e.g. the specific subjects for whom data were collected/observations made). An estimate of impact might be made when extrapolating results from a given epidemiological study onto a target population i.e. a population for which health outcomes (or associations with environmental variables) have not been specifically measured, but which can be considered similar enough to another observed population for those effects to be extrapolated.

For example, you may do a study of birth outcomes in a population of 5,000 mothers in Tehran, and measure their exposure to some air pollutant. You estimate the effect of air pollution on the birth outcome i.e. how much risk of the birth outcome is associated with a given level of air pollution. You may then calculate the impact of air pollution in other Iranian cities, by measuring air pollution in those cities and extrapolating your estimate of effect (from your smaller study) onto all mothers living in them.

Thank you very much Vedran Markotić

Just to clarify, though, I'm not asking what percentage of patients look up information on the Internet.  (That figure is high, as some studies show, but it does fluctuate across population groups, regions, and is heavily impacted by education, etc.).

The question I'm looking at is this:  Of the patients who look up information on the Internet, what percentage DO NOT tell their doctors about what they have found?  I think that, by very definition of the problem, a doctor would not be able to answer that question just by asking his/her patients, because, if they don't tell, then they don't tell.

This is a very real problem, because the research suggests that the figure is as high as 60-80%.  So, why are patients not telling their doctors?  and what are the patients doing with this information?  What does this figure say about the overall patient-doctor communication going on?  Is medical communication all just a one-way street?

Hello Manuel,

Although we did not publish on this subject, we have been using the Dreyfus model for reaching consensus between examiners and assessors for blueprinting and pre-exam training. Our impression is that it is not difficult to set up standards for both constructing stations and assessing clinical skills.

Probably you can use visualizations from here http://www.datavizcatalogue.com/ and give example from your specific domain which is medicine for you.

Hi Thuli!

I send you a my paper..

I wish you well in your work!

Check out the Medical Library Association at http://www.mlanet.org.

Here are some more articles that you may use to modify/adapt health consciousness scale.

Hope they help.

Dear Elisabeth,

i think it depends on the hierarchical level that you are looking at. most works looking at a more global and planetary system are more at the systems level with analysis less focus on geographical boundaries. theres tons of these studies from industrial ecology and environmental systems analysis research

theres also an area called "future studies" that u might be interested in

Hello Omar,

I think that the first thing you should read is the attached paper by Stegink. This should give you most of the information you need. But you may find the other papers useful as well.

Dear Moya Smith

I did not make an empirical study about your question, but I investigated the theory of health. This strongly supports that a good and positive personality development contributes to health. I call this the "personally acquired potential". If it is high, the individual is in a better position to successfully respond to the demands of life. You will find the article open access at the J.Publ.Health Policy 35, 363-386, 2014 (attached).

I wish you much success.

Hi Aaron Caseley,

The greatest difficulty is to occlude the blood vessel of the lower limb. In the upper limb is easier.  Moreover most of the patients are elderly, which would be a risk.

 Metabolic stress without vascular occlusion is possible (Schoenfeld and Contreras, 2013) (Attached) 

Attached an interesting article on the subject.

I have helped

Thank you!

Recently we published the next article:  Instrument for Assistance to Patients with Heart Failure in Use Extracorporeal Membrane Oxygenation(ecmo)/Regimar Carla Machado, Maria Purificacion Girones Guillem, Maria Teresa Cicero Lagana, Ana Lucia Gargione Sant'anna, Ramon Camano Puig and Joao Nelson Rodrigues Branco/Exp Clin Cardiol Vol 20 Issue8 pages 3237-3250 / 2014. We developed the research using delphi.

Many references have be given. In summary:

If you only need estimate “exception of the estimated mortality”, you do not need survival analyses. The death status is known: yes or no, you can use logistic regression,

The survival analysis analyzes the out outcome: time to death, study not only the death rate, but also how fast the event occurs (say death). A simple example, two treatments, each have 50 patients, both have 10 deaths following in a year, however, the 10 deaths occurred in months 1 for treatment 1, but the 10 deaths occurred in months 12. Using logistic model, study the death rate, there is no mortality rate difference for two treatments, but using survival, there is the difference on survival probability. Treatment 2 is better.

The survival data is incomplete, for those deaths, we know the survival time, but for those survival subjects, we only know they time they survived so far, they may die tomorrow, they may survival a long l time. We call those subjects “cancer”.   

Three methods: Kaplan-Meir (non-parameter), Proportional Hazard Model (Semi-parameter) and life regression are common used (parameter).

For the above, each subject only has one outcome: one death status and the time to death.

Read your statement “And I want to make statistics attendance of traning's health , where people come back”, it seems for each subject may have multiple events, such as hospital visiting.  For multiple time to event data:, you may use:

Marginal model, Conditional A model, Conditional B model.  By using different time to event coding.

Dear Alfonso

May attached article  work to solve your query.

Austin,

From where I sit, my reading of your description of intra-institutional variation in medication treatment patterns for the same clinical condition already suggests to me why you would not want to use multi-level modeling (MLM). MLM is most commonly used when there is a basis to assume there is an institutional homogeneity of pattern practice.  It (MLM) is then used to account for, and analyze cross institution variation, as if there is a common practice pattern within each institution to begin with, and your description of things counters that assumption.  In my experience, your description of intra-institutional variation is the more common reality of clinical practice, stemming from patient to patient variation in clinical circumstances, and is the main reason why MLM is not always appropriate for comparative variation analyses.  In my view, many advocates to use MLM, especially without considering essential assumptions, has taken on a form of method-idolatry, and it therefore does not deserve regular use for the above key reason - there commonly exists intra-institutional variation in practice patterns.

I think the model you choose needs to flow from your hypotheses about planned comparative differences that you do want to assess. If, for example, you want compare physician to physician differences, both within and across institutions, you will need sub groups of similar patient cases, with markers for treatment eligibility candidacy for each patient to determine ideal candidates for particular medications/procedures, so that you will be comparing ideal eligibles for each physician. And you will also need reliable markers for treating physicians to sub-group their "panel" of ideal eligible patients treated/not treated. I am assuming that you have a preferred treatment protocol that is guideline based, and that allows for determining patient specific eligibility for each and all treatments for which you want to observe variation, i.e., aspirin use, beta blockade, etc. Additionally, I am assuming you have abstraction case data to derive denominator eligibility status for each patient as well. 

Given these things, you should be able to determine for each physician, for their pool of ideal eligibles, for any treatment (medical/procedural), what their compliance rate relative to the guideline based - preferred practice would be, and what the range of rates of best practice is for each institution.  At this level of comparative analysis there is first, simple, descriptive statistics that let you see, without additional adjustments, what the variation in clinical practices may be relative to preferred guideline practice, which implicitly expects 100% compliance for all ideal eligibles. 

With those simple figures you can construct institutional comparisons, aggregating the pool of physician results, to see what variation exists across institutions relative to preferred best guideline practices, for each treatment.  

Then, with those findings you can pursue additional adjustment for physician, institutional and other community factors that might account for variation in practice, or patient outcomes, using some form of multivariate logistic analyses.  

Not knowing what details you have to work with in data or key hypotheses makes substantive suggestions challenging to offer, but I hope by making my assumptions somewhat clear, you may be able to make some headway on your variation analyses.  Best of luck.

Hi Arjyabrata, this is an interesting study and I am sure there are more aspects one could look at once your done answering your primary research questions. Do you also have any data on birth outcomes ? - Perinatal mortality; maternal near miss or congenital defects ? It would be interesting to study those, if you have that data. Let me know if I can help or collaborate in any way, just happy.

Did the reviewer think your particular health science module did not connect well with the health sciences, or was the reviewer talking about social science theory in general?  If they were arguing that a basic understanding of social science is unnecessary for those studying public health, I'd say they are dead wrong.  One of the biggest problems I see in the public health papers I read and edit is that the Introductions and Discussions are filled with naive perspectives on social science.  Without a grounding in social science theory, it's difficult for young scientists to understand when they're making assumptions that, in fact, should be argued for rather than presumed.  Also, with the current emphasis on mixed-methods studies, and the new turn to qualitative research, it's very important to ground researchers in social science methods.  How else are they going to choose methodology appropriate to their subject, or analyze qualitative data? Finally, scientific studies that reach across cultures must be rooted in an understanding of cultural difference and researchers must have a language in which they can discuss those differences. Otherwise it's difficult to see, much less challenge, ethnocentric paradigms.

Statistical issues in empirical health shouldn't be so different from those in econometrics... from my point of view, the most important thing is that you won't estimate correct standard errors if you don't account for the fact that the generated regressor is subject to estimation error itself - similar to IV estimation. If you can replicate the equation the generated regressor results from, you could use it directly as a first stage. As an alternative, you could try to bootstrap the standard errors (i.e. to use empirical rather than analytical inference).

Here are links to two "special issues" of the journal Forum: Qualitative Social Research that were devoted to the topic of secondary analysis of qualitative data:

Thanks for your answer. I am using the Quips tool specilized for prognostic factor studies

I think that the first step should be to establish an analytic model by which situations can be understood. Armed with that the problem and the appropriate solution can be determined.

There are two situations to consider:

1. The development of the condition of stunting

2. Recovery from stunting

I would suggest that the resource capture models could be a good starting point.

Consider this approach

Growth rate = n × e

Where n is the balance of nutrients and e is the efficiency of uptake/utilization.

Each of these parameters can be considered the sum of individual nutrients, with factors such as enteropathy and mycotoxins changing the efficiency. For instance Aflatoxin can interfere in protein synthesis, so exposure would result in a low protein efficiency, while the same toxin can result in decreased zinc status and prolong diarrhea impacting all nutrients.

Applied to a diagnostic tool the diet can be evaluated and the known deficiencies identified first, and the risk of others predicted. For instance an infant being fed enough corn, beans and veg but with a deficient growth rate will be at risk of aflatoxicosis,if the diet does not have gave the beans then the resource for growth is limiting.

Food security assessment is increasingly being expressed in terms of outcome instead of cause - thus most organizations around the world have been expressing current food security status using the Integrated Phase Classification (see www.ipcinfo.org). The IPC is a set of standardized tools that aim at providing a common way of classifiying the magnitude and severity of food insecurity. Most of these are focused on nutrition outcomes and 'evidence based' assessment that is comparable across cultures, economies and political systems. Thus nutrition is central to food security assessment.

This may be an option:

I have not used this, yet, but am looking for options for these same types of problems.

Reduction of data at the source is attractive from a data management point of view, but limits what you can do later when you discover wonderful new analysis methods, or unanticipated failures, etc.

Regards, Dave.

DICOM Part 3 contains the "DICOM model of the real world" and information object definitions.

IMHO this question addresses to 'open science' and 'open innovation' topics. If we regard some R&D outcome as a public good, there should be minor or no restrictions to access this knowledge. But usually most inventions are property of researchers or institutions, so the owners can do whatever they want. If a government treats some invention as a priority public good, it tries to fund the research or to buy out the results for open access. Therefore, in a market economy your question should be addressed to governments and policy makers and rearranged like this:

- what are the priority areas in which governments support open science and open innovation?

- what do they do to select and to support such activities and to make the results open?

Hi Rashad, Have a look at http://www.hcaf.biz/2012/reevaluate_risk.pdf were costs were case mix and inflation adjusted. Cheers Rod

Glutamate isn't actually bad despite its dubious connection to the "china food syndrome". It doesn't cause allergies (which would be pretty bad for one of the amino acids that is widely used to build proteins).

I may change the taste of food in a strange way, since people have different numbers of receptors for tasting it (the taste is called umami).

Dr. Popov is correct. Superoxide and other reactive oxygen species are also used as second messengers in more conventional transduction cascades, for example in coupling of G proteins to effectors such as ion channels, kinases, phosphatases, etc.. Free radicals are also widely used in the immune system. There is a class of enzymes, called NADPH oxidases (or NOX enzymes) whose sole function is to produce oxygen free radicals for use in signaling and in immune responses. This is why excessive quenching of free radicals -- overdosing on antioxidants -- actually produces adverse effects on health.

I think there are three factors in play here: 1) lack of time 2) lack of expertise 3) ideology or politics

1) As we know, there is a constant pressure to cut the costs of publishing papers. Therefore, in the name of saving money, there is not enough time to check all the facts and claims thoroughly.

2) Even if there was enough time, many journalists do not have the statistical and other skills to evaluate the reserach results themselves. Therefore, it all comes down to trusting people. Who do the journalists trust to present an objective opinion of a subject without a political or ideological agenda? Sometimes they choose the experts rights and sometimes not.

3) Both the journalists and the experts have some vision of "the perfect world". It is not easy to suppress these subjective views and present only the facts. The result is that the expert tells the journalist something colored with subjective views. The journalist adds his / her own subjective views when he / she cites the expert. The result is often a story with a mixture of facts and subjective views with no easy way to know what is a fact and what is an opinion.
