Growing a multicultural mindset

In deze training staan het zakelijk succes in combinatie met de culturele diversiteit centraal. Veel ondernemingen hebben multiculturele teams. Begrip van interculturele communicatie en bewust zijn van culturele verschillen maakt het verschil in de mate van succes. De bewustwording van culturele verschillen, het waarderen van die diversiteit en het aanpassen van het taalgebruik daarop, zal bijdragen aan zowel een betere onderlinge verstandhouding als een betere performance richting opdrachtgevers en stakeholders. Het krijgen van inzicht in drijfveren is een belangrijke voorwaarde om je eigen gedrag en dat van anderen te begrijpen en waar nodig bij te sturen. Deelnemers leren en oefenen effectiever te communiceren waarbij ze gebruik maken van hun eigen persoonlijke profiel. Een must voor teams die succesvol willen zijn in een internationale context.

Cursus Communicatie en Spreekvaardigheid

De cursus geeft u meer zelfvertrouwen in het spreken van Engels. De speerpunten van de cursus zijn het vloeiender en vlotter kunnen voeren van een inhoudelijk gesprek op uw vakgebied. Deelnemers oefenen tijdens de cursus het uitspreken van moeilijke klanken, woordenschat wordt opgefrist en uitgebreid en grammaticale structuren worden ingeslepen. De deelnemers bekwamen zich ook in het Engels wat nodig is op de werkvloer. Vaardigheden als het uiten van een mening, het maken van een statement, het doen van een voorstel, vragen om verduidelijking of herhaling van een woord of statement zullen gedurende de cursus worden ingeoefend. Deze cursus kan worden aangepast aan de wensen van de klant en het vakgebied.

Cursus Interculturele Communicatie

Welke competenties zijn belangrijk bij het effectief omgaan met mensen met andere achtergronden? Culturele empathie oftewel inlevingsvermogen; houden we bewust rekening met de gevoelens van mensen met een andere achtergrond? Een open houding; hebben we een onbevooroordeelde houding naar andere mensen. Flexibiliteit; vragen we uitleg over de cultuur van een ander? Welke competenties kunnen we ontwikkelen en welke zijn moeilijker aan te leren en dienen we rekening mee te houden tijdens communicatie. We gaan in deze training de competenties ontwikkelen, waardoor de deelnemers beter kunnen inspelen op situaties in onze multiculturele samenleving.

Assessments

De toenemende globalisering maakt dat u vaker klanten en zelfs medewerkers heeft die een andere taal spreken dan Nederlands. De voertaal tijdens vergaderingen, offerte besprekingen en gesprekken zal daardoor vaak het Engels zijn. Zijn uw medewerkers in staat om de internationale contacten te onderhouden. Wilt u weten welk niveau Engels uw medewerkers beheersen? Op basis van het European Framework of Reference (CEFR) worden de deelnemers ingeschaald. Het CEFR onderscheidt zes niveaus van taalbeheersing van beginner tot near- native. Het CEFR beschrijft vaardigheidsniveaus van taalbeheersing in termen van taalomvang, wat moet je kunnen en taalcomplexiteit, hoe goed moet je het kunnen? Elke deelvaardigheid, spreken, lezen, luisteren en lezen worden ingeschaald op de verschillende niveaus. Tijdens de assessments worden de competenties in kaart gebracht, waarna in overleg een opleidingstraject op maat kan worden ingezet.

What is the UVC dose for killing or disabling the COVID-19 virus?

Because the COVID-19 virus (SARS-CoV-2) is so new, the scientific community doesn’t yet have a specific deactivation dosage. However, we know the dosage values for comparable viruses in the same SARS virus family are 10-20 mJ/cm2 using direct UVC light at a wavelength of 254nm; this dosage will achieve 99.9% disinfection (i.e., inactivation) under controlled lab conditions. In real-life, the virus is often hidden or shaded from direct UVC light, reducing UVC’s effectiveness. To compensate, researchers are applying dosages of 1,000 - 3,000 mJ/cm2 to ensure 99.9% deactivation, the current CDC disinfection goal (see CDC’s recently published guidelines, online).

Can we use tanning beds to decontaminate PPE?

No. Tanning beds are not considered useful to decontaminate PPE. The lamps in tanning beds are emitting a spectrum of UVA and UVB, wavelengths between 300-400 nm. While there is some antimicrobial efficacy in the UVB spectrum, it is generally pretty low. The UVC portion of the spectrum, 220-280 nm, is much more effective for disinfection. Therefore, I’m afraid that tanning beds cannot be relied upon for this purpose. Theoretically, you could replace the lamps in a tanning bed with those that emit UVC, but you’d also have to remove the acrylic bed surface because UVC does not transmit through that material. By the time you do that much modification to the bed, you may as well build a simple disinfection device using UVC lamps from scratch.

Can we use UVC disinfection to reuse our N-95 masks as our supplies are limited?

There are several manufacturers now offering equipment dedicated to disinfecting N95 masks. We have the solutions and products for UVC disinfection. Note that we have the solutions and products also can provide your specific product. This list is intended to highlight vendors who are self-identifying as having devices that may be helpful during the covid-19 pandemic. That being said, the research community is scrambling right now to try to answer some of these questions as quickly as possible. See the following for some preliminary “educated guesses” about how to do it, in the context of disinfecting hospital masks. https://www.nebraskamed.com/sites/default/files/documents/covid-19/n-95-decon-process.pdf There is some thought in the UV community that UVC together with some other process, notably heating to 65C in a humid environment, or hydrogen peroxide vapor, might be a good multi-barrier process. The heating or hydrogen peroxide vapor can penetrate into material better than UV and is believed to be able to kill the SARS-CoV-2 virus, but it may be less effective against many of the other pathogens that still exist in hospital settings. The UVC can supplement the virus kill, while also killing many of these other pathogens.

Can the products I find on websites such as Amazon be safely used for medical disinfection?

Devices sold on general marketplaces such as Amazon and Alibaba are not regulated for their UV output, and devices sold as UV-C emitters cannot be guaranteed to perform as described. UV-C sources and devices should be purchased from trusted, reputable suppliers. Please consult with the supplier and see the IUVA Advice for further guidance.

Can You Use UVC for direct human disinfection?

UVC is damaging to the skin and to the eyes. DO NOT look at the UV light or expose any part of your body. UVC should not be, and is not intended for, use for direct human disinfection. A possible exception is far UV light (see the FAQ that is specific to far UV light).

How do operators remain safe when using UVC lights to clean surfaces?

• Like any disinfection system, UVC devices must be used properly to be safe.
• They all produce varying amounts of UVC light in wavelengths of 200~280nm. UVC light is much more energetic than normal sunlight, and can cause a severe sunburn-like reaction to your skin, and similarly, could damage the retina of your eye, if exposed.
• Some devices also produce ozone as part of their cycle, others produce light and heat like an arc welder, others move during their cycles. Hence, in general, machine-human safety needs to be considered with all disinfection devices.
• Suitable PPE should be worn at all times when there is a risk of UV exposure to the skin or eyes. Be aware of stray light from the UV source and avoid irradiation of reflective surfaces.
• These considerations should be addressed in the operations manual, in the user training, and appropriate safety compliance.

Would the use of UVC at 185nm wavelength, which generates ozone, be as effective as germicidal UVC or only 254nm?

Studies have shown that UVC light at wavelengths of 254nm-265nm disrupts the DNA/RNA replication process in the cells. Ozone is a toxic chemical produced by 185nm UVC light interacting with oxygen in the air, that disinfects much like any chemical disinfectant. While ozone does dissipate in time, it can be corrosive and its effects on the item being treated needs to be understood before being used. Also, it is a lung irritant, and is regulated by NIOSH as a known safety hazard.

Where can I find third-party testing of the efficacy of UVC lights?

Please contact us for your testing. Send the email to info@irtronix.com you questions, we can help you. Don't hesitate to ask questions.

We are looking into the use UVC light to disinfect certain areas of the electric power plants. Have you done any research on the noise that these devices can induce into electronics (EMI/RFI effect)?

Most UVC disinfection devices make UVC light using a fluorescent-light bulb; the bulb is unique, but otherwise the device uses ballasts, wiring and controls similar to any other fluorescent light fixtures. Other sources include LEDs (typically low voltage/low current) or xenon flash bulbs (using high voltage capacitor discharge circuits). The potential for EMI/RFI effects will vary accordingly.

Can you tell us more about the penetration of UVC through "normal household" items?

There is essentially zero penetration of UVC into any solid material that doesn’t otherwise transmit it – it would all be absorbed within a few microns. There are only a scant few materials that do transmit UVC: high-purity silicate glasses, very thin sections of certain fluoropolymers, sapphire, and some other crystals. Most other polymers, even if visibly transparent, are not at all transmissive UVC. I think thin sections of pure polyethylene can transmit some UVC, depending on its microstructure and how it was processed. It is probably safe to say that a thin enough film of any polymer could transmit UVC to some degree. Depending on how thick a cotton T-shirt is, it may allow some UVC to get through because of porosity (gaps between fibers/yarns) and some tiny amount of internal reflection, but otherwise cotton fibers do not transmit UVC, per se. Cardboard is as good as a brick wall. White paper or cardstock might transmit a bit of UVC based on the same principle like the cotton textile, but likely not much. Two generic tips:

• For a disinfection application in which you WANT something exposed to UVC, assume it has no penetration into the material at all. It is only a surface phenomenon.
• For a shielding application in which you DON’T want exposure to UVC, if you cannot see blue light from the lamp getting through the material, it is safe to assume that you have also blocked all the UVC.

How can you tell if "UV protective" glass and glass films are actually treated to block UVA rays. Is there an easy way to tell?

If you can get access to a UV spectrophotometer. which can record the transmittance of the glass or film as a function of wavelength, you can easily see if the UV rays (less than 400 nm) are blocked. One other way would be to get access to a UV lamp that is used in sun tanning parlors. If you expose this UV light to a white shirt, the shirt will glow blue due to fluorescence from the pigments in the shirt (this is the common “disco” effect). If you place the glass or film between the UV lamp and the shirt, the blue glow will disappear if the material blocks UV.

We keep seeing the terms ‘watts’ and ‘joules’ in descriptions of how much UV is required to disinfect something. What do these terms mean? Are they the same? Why are they important?

Most people seem to be familiar with the term ‘watts' (from light bulbs and electric bills); but probably not the term ‘joules' (a metric measurement term). In short, both are used in measuring energy in any form (e.g., electricity as well as light):

• A Watt is a measure of the rate of energy delivery (analogous to gallons-per-minute flow rate for water delivery).
• A Joule is a cumulative measure of the total amount of energy delivered (analogous to total gallons of water delivered).
