Due to the spread of the SARS-CoV-2 virus, most countries have tightened their public health policies. One way to limit the spread of the virus is to make mouth and nose cover compulsory in public spaces. The article presents the impact of wearing masks on the perception of thermal comfort. The following masks were analysed: FFP2, cotton, medical, PM2.5, half-face protective shield plastic and full-face protective shield plastic. The research was carried out for two scenarios of an ambient temperature: −20 and 30 °C. A thermal manikin was used for the tests. In the case of when a temperature equals 20 °C, the dry masks increase comfort, both general and local, while wet masks reduce comfort. On the other hand, at 30 °C, only wet masks do not increase discomfort. In addition, moist masks require less heat flux to achieve a certain skin temperature. However, it should be remembered that it is not advisable to wet the masks from the health point of view.

AbstrakHegemoni kolonialisme dalam budaya poskolonial merupakan alasan penelitian inikemudian mengkaji wacana kolonial dalam novel Max Havellar (MH) khususnya dampakditimbulkannya. Dampak dimaksud adalah posisi keberpihakan pemikiran tersirat darikarya tersebut. Hasil pembahasan menunjukkan, secara temporal maupun permanen MHmenyuarakan ketidakadilan dalam kondisi-kondisi kolonial menyangkut penindasan sangpenjajah terhadap terjajah. Hanya saja, upaya mengatasnamakan atau mewakili suarakaum terjajah terbukti mengimplikasikan ciri ideologis statis kerangka kolonialisme(orientalisme); yakni cara pandang Eropasentris, di mana “Barat” sebagai self adalah superior,dan “Timur” sebagai other adalah inferior. Dalam konteks poskolonialisme, MH dengan sifatkritisnya yang berupaya “menyuarakan” nasib pribumi terjajah, justru menampilkan stigmapenguatan kolonialitas itu sendiri secara hegemonik. Artinya, “menyuarakan” nasib pribumidimaknai sebagai keberpihankan kolonial yang kontradiktif, di mana stigma penguatankolonialitas justru lebih terasa, ujung-ujungnya melanggengkan hegemoni kolonial. Tidakmembela yang terjajah, tetapi memperhalus cara kerja mesin kolonial.AbstractThe hegemony of colonialism in the culture of postcolonial society is the reason this studythen examines the colonial discourse in the novel Max Havellar (MH) in particular the impactit brings. The impact in question is the implied position of thought in the work. The resultsof the discussion show that, temporarily or permanently, MH voiced injustice in the colonialconditions regarding the oppression of the colonist against the colonized. However, the effort toname or represent the voice of the colonized has proven to imply a static ideological characterin the framework of colonialism (orientalism); ie Eropacentric point of view, in which “West” asself is superior, and “East” as the other is the inferior. In the context of postcolonialism, MH withits critical nature that seeks to “voice” the fate of the colonized natives, actually presents thestigma of strengthening coloniality itself hegemonicly. That is, “voicing” the fate of the pribumiis interpreted as a contradictory colonial flare, where the stigma of strengthening colonialityis more pronounced, which ultimately perpetuates the hegemony of colonialism. No longerdefending the colonized, but refining the workings of the colonial machinery.

Abstract Akyem Abuakwa is one of the largest states of the Akan ethnic group in Ghana. Notwithstanding its size and important contribution to Ghana’s development, historians have paid little attention in doing academic research on the health history of the people. Using a qualitative method of research, this paper does a historical study on public health policies in Akyem Abuakwa from the 1850s to 1957. We utilised documentary and non-documentary sources to discuss the various public health policies implemented in Akyem Abuakwa from the pre-colonial era to the colonial era. We examined the impact of the policies on the people of Akyem Abuakwa and the various challenges faced by the British colonial administration in their quest to implement public health policies.

From a scientific point of view, the answer to the question might be quite straightforward in favour of routinely screening all pregnant women for pre-eclampsia (PE) during the first trimester of pregnancy. However, irrespective of the large amount of good evidence and expert opinion favourable for universally screening for obstetric syndromes, such as PE, public health policies do not always align with pure clinical science.

Purpose – The purpose of this paper is to help readers consider the value of identifying the values, beliefs, and vested interests of someone they wish to influence and to frame their idea, request, or call to action in a way that will make sense in the other person's internal model of the world and be interesting and attractive to him or her. Design/methodology/approach – The paper defines several key terms and presents a rationale for exploring the point of view of individuals one wishes to influence and framing an idea in a way that will be most meaningful to the other. Findings – There is no one way to view any idea. People have a set of mental filters that any influence attempt must pass through. These filters shape the impact and meaning of the other person's idea or request. The skillful influencer takes this into account in framing his or her influence approach. Research limitations/implications – This paper is the result of many years of observation and pattern recognition in situations where people are asked to influence one another. It is also consistent with current behavioral economics research, but is not itself based on laboratory research. Practical implications – Applying this approach should enable readers to have better results in influencing a variety of people. Originality/value – Influence is a key skill set for leaders and key contributors.

This report contemplates an instrumental composition as a project for audiovisual production in social isolation, during the Covid-19 pandemic. Based on the problematization of the impact of the pandemic in music making, solutions were sought that were not only viable as an artistic result but that could also be projected in a purposeful and prospective way in times of humanitarian crisis, of dismal symmetry between capitalist neoliberalism and programmed neglect in public health policies. After a description of the research on the use of art in past pandemics as a guiding principle in the choice of materials, the audiovisual production is detailed. The piece was written in April 2020 as a result of the analysis of a Renaissance motet, which, in turn, was conceived as a tribute to a composer who had perished from the plague and as a palliative against the disease.

Several SARS-CoV-2 variants have emerged around the world and the appearance of other variants depends on many factors. These new variants might have different characteristics that can affect the transmissibility and death rate. The administration of vaccines against the coronavirus disease 2019 (COVID-19) started in early December of 2020 and in some countries the vaccines will not soon be widely available. In this article, we study the impact of a new more transmissible SARS-CoV-2 strain on prevalence, hospitalizations, and deaths related to the SARS-CoV-2 virus. We study different scenarios regarding the transmissibility in order to provide a scientific support for public health policies and bring awareness of potential future situations related to the COVID-19 pandemic. We construct a compartmental mathematical model based on differential equations to study these different scenarios. In this way, we are able to understand how a new, more infectious strain of the virus can impact the dynamics of the COVID-19 pandemic. We study several metrics related to the possible outcomes of the COVID-19 pandemic in order to assess the impact of a higher transmissibility of a new SARS-CoV-2 strain on these metrics. We found that, even if the new variant has the same death rate, its high transmissibility can increase the number of infected people, those hospitalized, and deaths. The simulation results show that health institutions need to focus on increasing non-pharmaceutical interventions and the pace of vaccine inoculation since a new variant with higher transmissibility as, for example, VOC-202012/01 of lineage B.1.1.7, may cause more devastating outcomes in the population.

AbstractAdherence to public health policies such as the non-pharmaceutical interventions implemented against COVID-19 plays a major role in reducing infections and controlling the spread of the diseases. In addition, understanding the transmission dynamics of the disease is also important in order to make and implement efficient public health policies. In this paper, we developed an SEIR-type compartmental model to assess the impact of adherence to COVID-19 non-pharmaceutical interventions and indirect transmission on the dynamics of the disease. Our model considers both direct and indirect transmission routes and stratifies the population into two groups: those that adhere to COVID-19 non-pharmaceutical interventions (NPIs) and those that do not adhere to the NPIs. We compute the control reproduction number and the final epidemic size relation for our model and study the effect of different parameters of the model on these quantities. Our results show that direct transmission has more effect on the reproduction number and final epidemic size, relative to indirect transmission. In addition, we showed that there is a significant benefit in adhering to the COVID-19 NPIs.

While poverty and its causes have long been studied by economists, the link between chronic disease and food poverty has been a neglected area of research. This article investigates the impact of chronic disease on food poverty by using two rounds of panel data of Pakistan and linear probability regression framework. Chronic disease is defined to include diabetes, arthritis, heart disease, AIDS, cancer and asthma. The regression results show that on average the effect of chronic disease on food poverty is statistically equal to zero, but this effect significantly varies by income groups categorised by three non-income based classifications. We note that the incidence of chronic disease is significantly higher among non-poor when permanent income of the household is incorporated into the model, most notably among individuals coming from low- and middle-income backgrounds. Thus public health policies that seek awareness, prevention and treatment of chronic diseases have the potential to alleviate poverty in a high poverty environment.
