It is estimated (e.g. by IMO) that there is only 1-2% of women working at sea. What are the causes of this underrepresentation? Do women themselves are not willing to undertake such professional challenges? Are the socio-cultural obstacles (biases)? Maybe the sector needs more diversity management programmes? Maybe there are some legal obstacles, maybe in some countries or under some conventions women are not allowed to enter maritime professions? Do you think is there a growing tendency of women's presence at sea?
Relevant answer
Answer
1. Lack of knowledge and awareness: Women are often unaware of the opportunities available to them in maritime professions, and may not have access to the necessary resources to learn more about them.
2. Gender stereotypes: Women may face gender stereotypes and discrimination in the maritime industry, which can make it difficult for them to break into the field.
3. Lack of support: Women may have difficulty finding mentors, support networks, and job opportunities in the maritime industry, which can make it difficult for them to gain the experience needed to advance.
4. Physical requirements: Certain maritime professions may require physical strength and stamina that some women may not possess.
5. Cost: The cost of training and gaining the necessary certifications can be prohibitively high for some women.

Answer
One way to measure the impact of Occupational Health and Safety systems on productivity of a firm is to compare the firm's productivity before and after the implementation of Occupational Health and Safety systems. This can be done by tracking absenteeism, illness and injury rates, and other data related to the health and safety of employees. Additionally, the firm can measure the impact of these systems by tracking the firm's overall output, such as the number of goods produced or services provided, as well as the quality of those goods and services. Finally, surveys and interviews of employees and management can also provide valuable insights into the impact of Occupational Health and Safety systems on productivity.

Government laws require occupational biohazard management. However, they do not present guidelines on which methodology to apply. I guess it's because of the particularities of each occupation and organization. Do you know any methodology for the evaluation of biological risk, in which the calculation of the level of risk can be obtained?

This was first published almost 10 years ago.
Now almost a decade later, has there been any progress? Chronic workplace inactivity has been a pandemic in developed societies for much longer than a decade. The healthcare and productivity costs of workplace inactivity are all increasingly well documented. Unfortunately, this sentence from 2012 probably still applies: "Employers often provide break time and specific areas for smoking, yet to do this for exercise may be considered distracting, counterproductive, and/or too expensive." .
Thank you for considering this discussion.

Everybody have information about obesity but sitting for long can lead to muscle atrophy that observed in long bed rest patients or the astronauts. While sitting, anti-gravity bones and muscles relaxed and gravity influences decreases, similar phenomenon observed in space. As per the literature, bad lifestyle decreases bone density by 10% per 3-6 months. 6-9 hour sitting is playing havoc with workers life. Govt or company should provide compulsory walk or stretching sessions.

Occupational, Health and Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Now, the Sustainable Development has become a overused word. Almost all the developed and major developing countries are framing regulation for sustainable mining and authorities are concern about it. But, for the sustainable mining, there is a research gap between the existing practical conditions of the mining sector and requirements of sustainable mining. How can we fill the gap by research. What are the areas in which research could be done by the technocrats like mining engineers to fill the gap. I want to serve with my technical contribution to build a bridge with my research to mitigate the practical problems to achieve this goal. Please suggest, in which sector research could be done by the PhD scholars.

I am involved in an interactive implementation project as a researcher, collaborating with practitioners in identifying evidence-based pathways for making workplace improvements. I have three questions about this set-up:
What are the facilitators and barriers that you face in your interactive research projects?
What are the methods and tools that help you overcome the barriers you face in such project?
How do you follow and evaluate such processes on a meta level?
Relevant answer
Answer
Some Human Factors experiments lend themselves more easily to testing within such restrictions - and in some cases meet the criteria for asking questions around single operator performance (with or without confederates in another room). Biggest issue are experiments where you have to have to directly interact with your participants. More so when having to set-up physiological measures. Some electrode placement can be done by the participant, but many need experimenter assistance to ensure correct contact.
  • asked a question related to Occupational Health
Question

In medicine and labour law there are two widely accepted concepts. The first of them refers to the meaning of the work. Work is an activity, often regular and often done in exchange for a payment ("for a living").
The second concept refers to occupational disease, which refers to the pathology established by employment. This indicates a series of risk factors and working conditions that after a while end up generating a work-related illness.
In a large number of countries, the recognition of a work-related illness to a worker gives him access to a series of economic and welfare benefits. The above occurs after probationary processes where rating boards determine whether the origin of the pathology is due to occupational exposure or not.
However, in practice in occupational medicine we face that extra-labour risk factors - generally linked to home care activities such as washing, ironing, caring for older adults or children, etc. - are a criterion for qualifying as non-work diseases (usually musculoskeletal).
Are not activities associated with home care also a job? Why use these types of risk factors to ignore the occupational disease, especially in women?
Relevant answer
Answer
Yes..indeed a good point for us to examine both paid and paid work particularly among women with regard to diseases. However, I do think culture also plays a role in this aspect- as a lot of studies have pointed out that different risk factors might trigger different consequences for both men and women in relation to occupational diseases.

Hello Deep Thinkers,
Would like to invite you to become involved in a discussion related to my research on wage-earners/blue-collar workers and their avoidance of Mind-Body Practices (i.e., yoga and meditation) to manage stress. More specifically, why are wage-earners so under-engaged in meditation and/or yoga for stress relief in or out of the workplace, in-spite of re-enforcing positive health literature on Mind-Body Interventions?

Hi Mary,
The topic is interesting. Though not exactly similar but my area of work is - preference and choice in CAM and conventional medicine.
Meditation/yoga are part of complementary medicine and the effect of the same are not particularly understood by people at blue collar level, specially in underdeveloped and developed countries. Where yoga is understood as a form of exercise than its integrated mind body perspective and blue collar workers, mostly being active physical workers feels no further need for it.
Secondly, in most of the countries till date expenditure made on Yoga/Meditation is not covered by insurance.

It seems that the paradigm of the Social Determinants of Health is no longer enough to explain health - the dynamics of the disease. Is it time to propose new and better models of explanation?
Relevant answer
Answer
The way the initial question is posed makes me wonder if you thought that social determinants of health are supposed to explain all vulnerability to disease or all the factors needed for being healthy. The first three responses to the question all indicate that developing disease or staying healthy has multiple types of determinants. And, indeed, these can interact. Take a very simple disease such as influenza which right now is occurring in many parts of the world. The immediate cause of the disease is infection by the influenza virus. The virus potentially can infect anyone who does not have sufficient antibody to the particular strain of the virus that is "in circulation." But, the likelihood of exposure to the virus depends on the likelihood of contact with someone who is infectious. That, in turn, can be affected by the local population density - such as the number of persons who share a household. The severity of the disease can be affected by other factors such as poor nutritional status. So, even in this simple example there are multiple types of determinants of health and disease and severity, or impact, of disease.
It is also worth remembering that disease and health are not just physical states but also emotional states. There are factors that affect mental health. Furthermore, mental health and physical health can interact.
All this is well-known; and yet, I do not believe that anyone can state that we know exhaustively all the factors or possibly even the types of factors that can affect health and disease.

Goal programming is a branch of multiobjective optimization, which in turn is a branch of multi-criteria decision analysis (MCDA). This is an optimization program. It can be thought of as an extension or generalization of linear programming to handle multiple, normally conflicting objective measures. Each of these measures is given a goal or target value to be achieved. Unwanted deviations from this set of target values are then minimized in an achievement function. This can be a vector or a weighted sum dependent on the goal programming variant used. As satisfaction of the target is deemed to satisfy the decision maker(s), an underlying satisficing philosophy is assumed. Goal programming is used to perform three types of analysis:
Determine the required resources to achieve a desired set of objectives.
Determine the degree of attainment of the goals with the available resources.
Providing the best satisfying solution under a varying amount of resources and priorities of the goals.

In one of my studies I want to monitor HRV at two instances on a typical working day. Considering obtrusiveness, I want the protocol to be as short as possible. Preferably below 5 minutes. However, I've been having trouble finding a suitable measurement protocol. I hope you can provide me with some suggestions or references. Thanks in advance!
Relevant answer
Answer
Hi Sander,
1- It is not necessary to measure HRV in resting position, it all depends on your main question; are you going to measure resting HRV, then it must be in resting position after about 10 minutes of rest for 5 minutes and here is a guideline: http://www.ncbi.nlm.nih.gov/pubmed/8598068.
Of course the guideline is old and many questions remained unanswered such as if it's necessary to do paced breathing etc.... (I would recommend paced breathing of course)
2- When you have ~ 5 min recording then it's not ultra-short it's enough for most of the HRV measures. An ultra-short HRV means something below 1-2 min for example 10-30 seconds in that situation the best measures are time domain measures; such as RMSSD, SDNN. Pay attention that for frequency domain measures you need at least 5 minutes of recording according to the above guideline. 2 minutes may also be enough but not recommended.
3- You can use available free software such as Kubios for HRV analyses (it also provides you possibility of beat correction) but you need at least 30 seconds of recording for each sample. If you insert a sample of less than 30 second in Kubios it still gives you the HRV measures but if you insert a long sample in Kubios you cannot select less than 30 second of the sample for analyses.
4- If you are doing research I strongly recommend you to not rely on any commercial device that only give you the HRV. Always look for those devices that give you the raw ECG signal (and not PPG signal) as you always need to correct the beats. Even few wrongly detected beats can considerably deviate the HRV measures. Also, the device must have a sampling rate of at least 200-500 Hz not lower, according to the guideline.
Good luck !

Question
2 answers
Many policy advocates, a few mainstream politicians, and some economists propose that free markets can manage environmental problems as a sole solution. That seems unlikely, because of market distortions, perverse incentives, incomplete information, long lead times before markets are likely to respond to health issues, and weak "signals" of environmental damage that change behavior of producers. Obviously there are ideological implications derived from liberalism/laissez-faire capitalism and as a minority opinion it is primarily an "Anglo-Saxon" (i.e. North American, UK, Australian, not so much NZ) point of view. However, the notion has produced an enormous number of books, papers, and reports. On the other hand, I don't see very many analyses specifically on the role of free markets as an "80%" solution (Pareto Principle), managing most problems most of the time and reducing the burden of regulation but not the need for it. This seems to me to be pivotal in environmental/occupational health policy but not much remarked upon. Maybe it is too obvious or maybe it is oversimplistic. Do you know of a body of literature that treats free markets as an essential but partial solution to societal risk management?
Relevant answer
Answer
Maybe I should have worded the question differently. Of course there is a literature on free markets. Is there a coherent literature on the action of markets as partial solutions and how they reduce the scope necessary for regulation to fine-tune? It seems like the economics literature is distorted into a free-market school and a regulatory-favorable school without much thought given to how a well-functioning market reduces but will never eliminate competent regulation. That's what I mean by an 80% solution - taking care of most problems and leaving less for regulation to have to deal with.
It just seems to me that someone should have studied the dynamics of how these problems get solved with tradeoffs between market solutions and the inevitable need for regulation to get it right. Most economic theory seems to think that regulation is a blunt instrument and markets get things spot on, but I don't see it. I think that markets are the blunt instrument and sound regulation fine-tunes the environmental problems.
My sense is that that is how markets actually work but I have found few economists who think in those terms.

I want to correlate the influence of seasonality in air pollution with hospital admissions for pulmonary diseases. However I find that though air pollutants are minimum in concentration during monsoon, hospital admissions for pulmonary diseases are maximum.
What can be the reason and how can I relate it to my data.
Literature, ideas and help are very welcome.
Thanks
Relevant answer
Answer
like with any correlation, there can be multiple reasons for the behavior you observe - first of all, did you try to vary the lag? I mean, if one takes a weekly averaged concentration of pollutants (A) vs number of admitted patients (B) and builds a linear correlation coefficient for A and B series, moving B forward in 1 week increments, one can detect a 2-3 week lag between the cause and the consequence. If you prove that the k_corr is maximal for, let's say, 3 week lag (and k_corr is large) and shows the same behavior each year then at least there will be a subject for the discussion.

Dear @Maria, I wish you success with building a vigilance protocol for workers of a small industrial plant in the field of ready-made meals. I do hope that this might help you in general. "Workers at risk of heat stress include outdoor workers and workers in hot environments such as fire-fighters, bakery workers, farmers, construction workers, miners, boiler room workers, factory workers, and others. Workers at greater risk of heat stress include those who are 65 years of age or older, are overweight, have heart disease or high blood pressure, or take medications that may be affected by extreme heat.
Prevention of heat stress in workers is important. Employers should provide training to workers so they understand what heat stress is, how it affects their health and safety, and how it can be prevented..." Different types of heat stress are treated! 
A brochure Protecting Yourself from Heat Stress is attached for dear @Maria.

Hiya, doing some work looking at the relationship between comorbidities and employment. Looking at the WLQ to measure work disability, but wondered if anyone knew of anything specifically for comorbidities.

Answer
Dear Karen,
1). From employees’ perspective, self-reported work ability by using Work Ability Index questionnaire (WAI) is a reliable instrument in order to keep active during working life, especially for workers with chronic diseases. In my opinion, work limitations should be examined very carefully.
2). From employers’ perspective, there is much more interest for sick leave absenteeism, which can be assessed by the number of total paid sick days and other certain formulas.
I do not know if these aspects are covering your area of interest, but I’m speaking from the perspective of occupational health services. Rehabilitation and socio-professional integration of people with impaired work ability is of great interest for these services (multidisciplinary approach).
Best regards!

I am doing a study on welders on their KAP on occupational health. I have to get verbal consent from employers before I administer my questionnaire to welders. If the employer does not give consent, how do I report/calculate the non-response rate? Usually 4-5 welders work under an employer. 
Relevant answer
Answer
Avinav - 
It may be adequate and clearly understood if you just kept a weighted employer nonresponse rate and a nonresponse rate for the 'eligible' welders.  However, if the tendency for an employer to allow welders to respond seems related to number of employees, you may want to break your data into groups based on size (number of employees).  You may want to see if response propensity is related to other characteristics as well. 
Your study seems to relate to the concept of "nonignorable nonresponse," which you may want to research. (Note that "ignorable" nonresponse is not really "ignorable.")

All ethoxylated materials are said to contain trace amounts of EO and 1, 4 Dioxane. If my product contains well bellow .1% of ethylene oxide, does this need to be mentioned in the SDS in order to be compliant with California Prop 65? 
According to The Office of Environmental Health Hazard Assessment (http://oehha.ca.gov/prop65/crnr_notices/admin_listing/requests_info/092013ChangeBasis.html) regarding Prop 65 and ethylene oxide.
Prior to June 1, 2016, employers may use the following legend in lieu of that specified in paragraph (j)(2)(i)(A) of this section:
“DANGER ETHYLENE OXIDE CANCER HAZARD AND REPRODUCTIVE HAZARD AUTHORIZED PERSONNEL ONLY ”
“1910.1047(j)(2)(ii)(A)
The employer shall ensure that labels are affixed to all containers of EtO [ethylene oxide] whose contents are capable of causing employee exposure at or above the action level or whose contents may reasonably be foreseen to cause employee exposure above the excursion limit, and that the labels remain affixed when the containers of EtO leave the workplace. For the purposes of this paragraph (j)(2)(ii), reaction vessels, storage tanks, and pipes or piping systems are not considered to be containers.”
"Action level" means a concentration of airborne EtO of 0.5 ppm calculated as an eight (8)-hour time-weighted average (https://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=standards&p_id=10070).
So here's my math:
.5/1,000,000= 0.0000005
0.0000005 x 100=0.00005%
I can't find a clear answer, or if there's a new regulation concerning EO. Many of our products would only contain trace amounts, if any at all since EO is extremely volatile and they were not required to be reported before, but the UN's Global Harmonizing System or California may have changed the rules.
Relevant answer
Answer
Hello,
Proposition 65 is specific to California. This is sometimes considered a "right to know" regulation and is separate from OSHA or other occupational regulations, and is independent from the federal government.
Proposition 65 requires that a clear and reasonable warning be provided on a product that contains a chemical known to the State of California to cause cancer or birth defects (ethylene oxide is listed as both) IF the exposure from using the product would be above what is called a "Safe Harbor Level (SHL)."  It is complicated because the SHL is in units of micrograms/day instead of as a concentration.  For ethylene oxide there is a cancer endpoint SHL of 2 microgram/day and a developmental toxicity endpoint SHL of 20 microgram/day. http://oehha.ca.gov/prop65/pdf/safeharbor081513.pdf
For a volatile substance, you could calculate workplace exposure by determining how much might be released into the breathing space of the worker (convert to a unit of microgram/cubic meter and then multiply that by the amount of air that someone would breath in during an 8 hour work day (m3/hr x 8 hr/day) using the product.  If the result you get (microgram/day) using reasonable conservative assumptions (e.g., high activity job) is greater than the SHL then a prop 65 warning would be required.  If there is potential for skin contact and hand to mouth indirect ingestion that would also need to added to the exposure amount.  Often you can find proposition 65 warnings on section 15 (other regulatory information) of an MSDS.  However, note that OEHHA which is responsible for Proposition 65 is currently working on updating the requirements for what constitutes a "clear and reasonable warning".  Any changes should be posted to their website

Yes Yochai - the posts, so far, have been trying to further understand the nature of what it is that you are actually doing or wanting to do. I get the impression that you have not implemented organizational policy change - but you are wanting to. The tool posted by Stefan is a useful one - but instruments such as this assess a 'snapshot' of the current state of play in an organization. You have said that you want to assess actual change. My recommendation would be not to think about a measuring tool - but an actual approach. Participatory Action Research (PAR) is a valid and recognized approach (call it a measuring tool if you want - as it contains regular use of both process and outcome evaluation) to implementing and assessing organizational change related to health promotion programmes. Here is a past article of mine that highlights how it is implemented and illustrates a framework model that demonstrates its processes.

I am creating a blended occupational health and safety management course. Many of my undergraduate students do not have much industry experience and so I often use videos and online interactive materials to expose them to unsafe acts and unsafe conditions in practice, since there is limited opportunity for field trips, and only one large application project for the semester. Students need to get exposure to typical conditions that they might see in the workplace, and I use traditional lectures, guest lectures, collaborative group activities, many photos and videos, blogs and website referrals, and even some physical demonstrations. Which topics/areas do you think would be best suited to delivery through online classes?
Relevant answer
Answer
I am a Ryerson University graduate on Occupational Health and Safety, and have long teaching and working experience in this area. From my academic and professional practice experience, I must agree with Roland. 
I would work up like to dress up the curriculum with core courses, optional courses (need-based), and practicum. Delivery method would depend on the skills and availability of infrastructure for media-based or in-class facilities. In Canada, we have excellent online courses, intensive in-class sessions, and regular in-class course design. 
Since OHS relates to human life risks or safety concerns, this programs requires intensive multi-dimensional appraisal for designing. I would suggest the following core courses:
1. Introductory course on occupational health
2. Risk identification and hazard management (2 courses each of 3 credits)
3. Measurement and analysis
4. Laws - OHS laws, human rights codes, and basics about the constitutional rights and privileges
5. Integrated disability management 
6. Ergonomics
You can add some simulations for the students. Practicum placement into any workplace, and writing a report in the end (project/ debriefing/data-based report etc.) can be the valuable components.

Relevant answer
Answer
A formal job analysis is best practice to measure risks associated with workplace injuries. A job analysis may reveal up to 6 factors known to predispose workers to injury. They are the following: prolonged awkward postures, excessive forces, repetitive movement, mechanical trauma, temperature extremes, and vibration. A battery of tools can be used to assess for risk factors and you can find information on such tools here: 
Some work describes epidemiology and risks in this population: 
I'm not aware of any intervention studies but the interventions would address reducing ergonomic risks through modifying work-practices, modifying the environment, using ergonomically designed equipment, modifying the scheduling of these procedures to offer breaks, etc. 
Sounds as if a more systematic approach towards assessing risks is needed in the literature. Such will help to guide future intervention studies. Hope this helps.

Are all 12 items used to calculate the PCS and MCS? The directions I found weigh each item differently, with different weights for each component score, and that the sum of the items is added/subtracted from a national norm (or something like that). I want to confirm this is the standard way of generating the PCS and MCS from the SF-12. Thanks in advance for the help!

Quality Metrics, the owner of the SF12, no longer provides the scoring algorithm in order to foster the use of their scoring software for accuracy. We have used both their scoring software and our algorithms for calculating subscale and scale scores; you describe the correct the correct approach, and the older manuals clearly describe the many required steps. You are correct that all 12 items in the SF12 are used for the MCS and PCS. Some folks (and I am one) recommend using only the MCS and PCS from the SF12, and not the subscales, because the subscale reliabilities are lower (and not really acceptable) compared to the corresponding subscales in the SF36 (which has 3 times more items !).

Seeking help with my dissertation topic, the topic is "negative impact of workplace stress on health".
Relevant answer
Answer
Yes! this is largely psychological in manifestation although it does manifest physically as well. There are physical and emotional stressors at work. being exposed to any of these depends on your type of work, organizational climate and your control over your job. For example, workers in the construction industry are more prone to physical stress, which results in health issues like MSD, chronic fatigue etc. while some office workers develop psychological health problems like anxiety, nervousness, fear, outbursts or breakdowns as a result of being predisposed to psychological stressors like bullyish boss, isolation by colleagues, colleagues playing pranks, job insecurity etc. Cases of these have been recorded
Also remember that health is not only the absence of disease (as defined by WHO). It also also incudes social and mental wellbeing. So if you look at it from the social and mental wellbeing perspective, you will find out that workplace stress do affect health.
But to be on the affirmative, the answer is 'yes'..

As has been stated by our colleagues, there are a lot of methods and criteria to assess the risk related to biomechanical overload. The choice of method should take different criteria into account: epidemiologic validation, risk factors considered, precision, time spent, and the effort of implementation, among others.
But you should consider that the practitioner would need prior training to apply these methods in a reliable way.
Speaking of small companies, my recommendation is to start applying the "quick assessment method" proposed in the new ISO document "ISO TR 12295". It was published in 2014.

This means that people keep working in unsafe manner. Employers keep exposing their employees to hazards. Some countries do have the legislation but enforcement is weak. This is all about the government's commitment. You find this in most developing countries
2. Awareness on the part of the populace where majority of the general public know little or nothing health and safety at work. Knowledge is power..

Hello,
Your equation is described in this paper:
The term Reference Dose (RfD) is used by the U.S. Environmental Protection Agency and it is a measure of daily exposure that should not be associated with non-cancer adverse effects. (Kind of like an ADI)
The THQ has been used to assess metal exposures from soil or vegetable ingestion. It is unitless or more precisely mg/mg if the values are entered into the equation correctly and in the proper units. Basically if the top of the equation (EF x FD x DIM) is a smaller value than the bottom of equation (RfD x W x T) then the exposure to metals from the source (e.g., vegetables) is less than the dose (adjusted Reference Dose) determined not be associated with non-cancer adverse effects.
As stated in the paper "A small value of the index (<1) shows reduced health
hazard and a value between 1 and 5 represents a concern level for health hazard"

Our journal happens to be very old - it started in 1919 - and my colleagues and I have been interested in its history and how it shaped the field particularly in the early years.
We have arranged for a collection of articles on the literature of environmental and occupational health to be made available for free to our colleagues, especially for the benefit of new investigators and for teachers to make available to their students.
Starting in 2005, the journal ran a series of editorials by myself on the structure of the literature of our field, and a series of historical essays by our Deputy Editor, Derek Smith (University of Newcastle, Australia). We now want to make those articles available to readers who missed them when they first came out.
