Synthesis and Characterization of Dense Carbon Films as Model Surfaces to Estimate Electron Transfer Kinetics on Redox Flow Battery Electrodes
Authors: Wan Charles , Ismail Akram , Quinn Alexander , Chiang Yet-Ming , Brushett Fikile
Published: August 2022

Redox flow batteries (RFBs) are a promising electrochemical technology for the efficient and reliable delivery of electricity, providing opportunities to integrate intermittent renewable resources and to support unreliable and/or aging grid infrastructure. Within the RFB, porous carbonaceous electrodes facilitate the electrochemical reactions, distribute the flowing electrolyte, and conduct electrons. Understanding electrode reaction kinetics is crucial for improving RFB performance and lowering costs. However, assessing reaction kinetics on porous electrodes is challenging as their complex structure frustrates canonical electroanalytical techniques used to quantify performance descriptors. Here, we outline a strategy to estimate electron transfer kinetics on planar electrode materials of similar surface chemistry to those used in RFBs. First, we describe a bottom-up synthetic process to produce flat, dense carbon films to enable evaluation of electron transfer kinetics using traditional electrochemical approaches. Next, we characterize physicochemical properties of the films using a suite of spectroscopic methods, confirming that their surface characteristics align with those of widely-used porous electrodes. Last, we study the electrochemical performance of the films in a custom-designed cell architecture, extracting intrinsic heterogeneous kinetic rate constants for two iron-based redox couples in aqueous electrolytes using standard electrochemical methods (i.e., cyclic voltammetry, electrochemical impedance spectroscopy). We anticipate that the synthetic methods and experimental protocols described here are applicable to a range of electrocatalysts and redox couples.

In December 2021, Molecular Forecaster (MFI) applied to participate in the inaugural CACHE Challenge. Organized by the Structural Genomics Consortium (SGC), CACHE (Critical Assessment of Computational Hit-finding Experiments) is a public–private partnership benchmarking initiative to enable the development of computational methods “to compare and improve small-molecule hit-finding algorithms through cycles of prediction and experimental testing.” As a Research-as-a-Service (RaaS) start-up in computer-aided drug design, MFI has a clear focus: to help kickstart drug discovery programs around the world with our software and expertise. It’s social impact that drives our mission and we are in business to help people, to further science, and to make drug discovery more efficient. However, because much of MFI’s work and contributions are bound by NDA, we cannot share the information publicly. This is why the CACHE framework is energizing and exciting to our team: we have the opportunity to collaborate beyond typical confidentiality limitations and to support researchers by sharing what we do and how we do it in a broader context. The MFI team has decided to take multiple research-focused approaches to our predictions in this first CACHE challenge, aiming to learn from our successes and failures. We are putting MFI’s team, expertise, and algorithms to the test, using them as a foundation to push the boundaries beyond our scientific and application successes to-date. We’ve also decided to double-down and share the details of our work with the community. Over the next several months, you will get a closer look at the way we approach scientific problems and push projects forward at MFI.

The largest state income in Indonesia is tax. So it is necessary to study the allocation and distribution of these taxes from the perspective of Islamic economics, this is because Indonesia has the largest Muslim population in the world. Indonesian state income from an Islamic economic perspective is very important, this is because the Islamic economy in Indonesia currently has great opportunities in its development aspect. Especially at this time, it has been recorded in the history of the economy in Indonesia as evidence of the development of the Islamic economy in Indonesia, including the existence of the embodiment of the National Money Waqf Movement and the Islamic Economic Brand. The purpose of this study aims to reveal about: the allocation and distribution of state revenues from the perspective of Islamic Economics on Existence (Sharia Economic Brand and Cash Waqf); and its relevance in Indonesia in the current era (4.0). The method used in this research is library research whose sources are in the form of library data in the form of various books, journals, internet, and also other sources relevant to the theme of allocation and distribution of state income in Islam. The results show that the allocation and distribution of state revenues, when viewed from the perspective of Islamic Economics, has the concept of Rahmatan Lil 'Alamin, meaning equal distribution of ability or income for the community that can be applied in Indonesia, one of which is through the national movement of cash waqf and the Islamic economic brand.

Why are there more accidents on Mondays? Economic incentives, ergonomics or externalities
Authors: Poland Michelle , Sin Isabelle , Stillman Steven
Published: August 2022

Research consistently finds more workplace injuries occur on Mondays than on other weekdays. One hypothesis is that workers fraudulently claim that off-the-job weekend sprains and strains occurred at work on the Monday in order to receive workers’ compensation. We test this using data from New Zealand, where compensation is virtually identical whether or not an injury occurs at work. We still find that work claims, especially sprains and strains, occur disproportionately on Mondays, although less than in other jurisdictions. This suggests fraudulent claims in other countries are just one part of the story. Furthermore, we find work claims remain high on Tuesdays, and that workers’ sprains and strains that occur off-the-job also disproportionately fall on Mondays. Sprains and strains treated at hospitals, which are not closed over the weekend, are also elevated on Mondays. However, Monday lost-time injuries are less severe than injuries on other days. Our findings are consistent with a physiological mechanism contributing to elevated Monday injury claims in New Zealand, but do not suggest doctors’ offices being closed over the weekend, ergonomic explanations, or work being riskier on Mondays play important roles.
Projecting the effect of climate change-induced increases in extreme rainfall on residential property damages: A case study from New Zealand
Authors: Pastor-Paz Jacob , Noy Ilan , Sin Isabelle , Sood Abha , Fleming-Munoz David , Owen Sally
Published: August 2022

New Zealand’s public insurer, the Earthquake Commission (EQC), provides residential insurance for some weather-related damage. Climate change and the expected increase in intensity and frequency of extreme weather-related events are likely to translate into higher damages and thus an additional financial liability for the EQC. We project future insured damages from extreme precipitation events associated with future projected climatic change. We first estimate the empirical relationship between extreme precipitation events and the EQC’s weather-related insurance claims based on a complete dataset of all claims from 2000 to 2017. We then use this estimated relationship, together with climate projections based on future greenhouse gases concentration scenarios from six different dynamically downscaled Regional Climate Models, to predict the impact of future extreme precipitation events on EQC liabilities for different time horizons up to the year 2100. Our results show predicted adverse impacts that vary -increase or decrease over time and space. The percent change between projected and past damages—the climate change signal—ranges between an increase of 7% and 8% higher in the period 2020 to 2040, and between 9% and 25% higher in the period 2080 to 2100. We also provide detail caveats as to why these quantities might be mis-estimated. The projected increase in the public insurer’s liabilities could also be used to inform private insurers, regulators, and policymakers who are assessing the future performance of both the public and private insurers that cover weatherrelated risks in the face of climatic change.
Modelling urban development in New Zealand
Authors: Donovan Stuart , Grimes Arthur , Maré David C.
Published: August 2022

We formulate and estimate a simple dynamic spatial general equilibrium model of urban development. Notwithstanding its simplicity, the model allows for adjustment frictions in housing markets; workers with heterogeneous productivities and preferences; and agglomeration economies in production and consumption. We estimate our model as a system of equations using panel data for workers residing in 132 urban settlements in New Zealand for the period 1976 to 2013. In terms of housing markets, we find strong evidence of increasing marginal costs and large adjustment frictions. The latter suggests demand shocks lead to temporarily elevated prices. In terms of agglomeration economies, we find New Zealand’s cities and towns offer economies of scale to producers, in the form of higher wages, but diseconomies of scale to consumers. By exploiting the panel structure of our data, we consider whether our findings are stable over time. We use the results of our model to compare relative productivity and amenity levels in New Zealand’s cities and towns and consider implications for research and policy.
Living on the edge: An anatomy of New Zealand’s most productive firms
Authors: Fabling Richard
Published: August 2022

Theory and international evidence suggest that firms at the New Zealand productivity frontier may be especially important for the diffusion of knowledge from the global productivity frontier, acting as a conduit for new technologies and ideas to flow into the domestic economy. We identify the NZ productivity frontier in a novel way that is robust to some sources of measurement error, and to criticism that the frontier label is dependent on arbitrary assumptions. We show that economic activity is concentrated in the upper deciles of the productivity distribution, and that frontier firms are disproportionately important to aggregate output, even relative to firms just outside the frontier. Compared to laggard firms, frontier firms: employ a more skilled workforce concentrated in major Urban Areas (particularly Auckland); have superior human resource management practices; are more export intensive; are more likely to have up-to-date technology (including UFB use); and to be in markets with no competitors.
Monitoring enjoyment of the rights to adequate housing and health care and protection in Aotearoa New Zealand
Authors: Mitchell Livvy , Baylis Paddy , Randolph Susan
Published: August 2022

This study evaluates how well the New Zealand Government is complying with its obligations under the International Covenant for Economic, Social, and Cultural Rights (ICESCR) regarding the right to adequate housing and the right to health care and protection. This study is novel in that it is the first study to extensively use quantitative performance indicators in addition to several qualitative indicators. While we find some areas of compliance for both the right to adequate housing and the right to health care and protection, the study reveals serious and significant violations of the ICESCR. The structural indicators reveal pervasive breaches in the New Zealand Government’s commitment to respect each right, while the process and outcome indicators reveal breaches in the New Zealand Government’s commitment to protect and fulfil each right. In particular, we find: (1) the two rights are not explicitly and fully recognised in domestic laws or in strategic plans, policies and measures; (2) well over half of the indicators examined reveal breaches in the obligations to use the maximum of available resources to ensure the two rights; (3) fewer than half the indicators evaluated show compliance with the obligation to progressively realise the two rights; (4) all but two of the indicators used to evaluate the New Zealand Government’s compliance with its minimum core obligations reveal breaches; (5) a sizable number of the indicators evaluated show breaches of non-retrogression— that is, reductions in the percentage of the population enjoying the rights; and finally, (6) there is evidence of serious and persistent structural, direct, and indirect discrimination among many population subgroups and especially between Māori and non-Māori.
Accounting for social difference when measuring cultural diversity
Authors: Maré David C. , Poot Jacques
Published: August 2022

In this paper we introduce a measure of cultural diversity that takes ‘social difference’ between country of birth and ethnic groups into account. We measure social difference using exploratory factor analysis of subjective identity, attitude and value responses in Aotearoa New Zealand’s 2016 General Social Survey. We examine the level of, and change in, our social difference-based measure of cultural diversity in 31 urban areas between 1976 and 2018, using census data. We compare these patterns with those derived from a standard fractionalisation measure of diversity based on population composition by country of birth and ethnicity. We find that the two diversity measures are highly correlated across the urban areas. Diversity increased everywhere between 1976 and 2018, whether social difference is taken into account or not. However, the social difference-based measure increased much faster than the standard measure in all but one of the urban areas. This suggests that growth in the fractionalisation measure of diversity is likely to have underestimated the trend in experienced social difference. Both measures also show evidence of spatial convergence in diversity: urban areas with low diversity in 1976 – which tended to be in the South Island – exhibited faster increases. Population diversity increased strikingly in Queenstown, which was the 19th most diverse urban area in 1976, in terms of social difference, but second only to Auckland in 2018.

Assistance in the application of IoT-based monitoring and watering system technology in the cultivation of family medicinal plants (Toga) for the PKK group managing the Tosabu garden, Kramas Sub-district, Tembalang District, Semarang, aims to assist park managers, namely the Kramas Village PKK administrator, in caring for and cultivating various types of medicinal plants in a mini greenhouse with an area of 40 m2. Watering plants is a significant problem during the dry season. In addition, the restrictions on activities during the COVID-19 pandemic have also become an obstacle for park managers to take care of plants intensively. This happens because there is no regular system for watering plants due to the busyness of the gardeners. The implementation method in service starts from site surveys and problem inventory, system design and manufacture, installation, training for managers, and evaluation. Technology was designed and built using Arduino Uno and Nodemcu ESP8266 as the central controller and the Blynk application to monitor and control the system using a smartphone. The system is equipped with several sensors, including DHT11 as a temperature and humidity sensor, a soil moisture sensor, and a rain sensor. Twenty-four mini sprinkler sprayer nozzles are used as plant sprinklers installed on each side and top of the greenhouse. The sprinkler and plant monitoring system that has been made has been successfully tested and works well. The plant watering system created can operate automatically using a smartphone and manual operation. The results of the application of this technology can be used by partners and can overcome the problems faced in treating and cultivating family medicinal plants efficiently

The weakness of the learning process is one of the problems in Indonesia's education world today. In the learning process, children are less encouraged to develop thinking skills, and they tend to be directed to memorize information so that students are more theoretically brilliant but weak in the application. Coupled with distance learning also gives unsatisfactory results for students because they only receive material without not being practiced. There is a need for changes in the learning process. The purpose of this community service activity is to provide assistance on practical Fiqh learning to teachers at SD IT Bina Insani Muslim. Although the study of material on Fiqh is practically not too deep, it is hoped that the teacher will be able to provide the whole teaching because Islam gives more attention to daily worship. To achieve this goal, training and mentoring SD IT Bina Insani Muslim teachers is a need of Islamic Fiqh Learning (Practical Fiqh). This service activity was carried out at SD IT Bina Insani Muslim in Jatimulya Tambun Selatan. Service partners are all teachers at SD IT Bina Islam Muslim. This service was held on June 14 and 15, 2021. Located in the hall of SDIT Bina Islam Muslim, attended by 23 teachers who were divided into two sessions. Given that the COVID pandemic has not yet ended, this training and mentoring event is divided into two days. The methods used in this implementation are lectures and demonstrations or direct training. The results of community service activities are increasing the ability and understanding of educators in terms of practical fiqh material and increasing and developing the understanding of educator participants in terms of fiqh problems in everyday life

Improving technological competence in an organization can be done in various ways. One of them can be done by conducting training on the technology. Like the Rabak Branch of the Nasyiatul 'Aisyiyah organization, related technology training, until now, is still rarely done. One of the activities that technological tools can support is making handicrafts. However, the activity of making handicrafts is still done traditionally. Often do not arrive at the expected result. This condition makes the activity of making handicrafts not optimal. Even the modules used are usually unavailable, so each member of Nasyiatul 'Aisyiyah cannot finish making these handicrafts after the activity. Therefore, this community service activity aims to introduce android-based technology in the form of handicraft applications and to help Nasyiatul 'Aisyiyah members make handicrafts. The implementation methods in this community service activity include giving lectures explaining handcraft applications, assisting participants, and direct practice using handcraft applications. The activity is carried out offline, which is located in Bustanul Athfal 'Aisyiyah Rabak. The steps in this community service activity start from preparation, implementation, and evaluation. The implementation of this community service activity indicates that the handcraft application training activities are included in good criteria, with the evaluation value from the results of the questionnaire calculation showing the figure of 79.58%. This shows that most of the participants have been able to understand and use handcraft applications in making handicrafts

The times have increased competition in all sectors of life. Along with the progress of the times, science also continues to grow. Knowledge is used to answer various human needs, increasingly fierce competition in organizations that require various strategies to survive and win the competition. SWOT analysis is one of the sciences used to produce this strategy (Strength=Strength, Weakness=Weakness, Opportunity=Opportunity, Threat=Threat). This analysis is to see the internal and external conditions of an organization. Likewise, the world of education, in this case, schools, needs to do a SWOT analysis to compete and have quality. The increasing number of schools will make the competition even more challenging, so the quality of schools must be crucial. This training activity aims to provide an understanding to the principal, functionaries, teachers, and employees of the importance of conducting a SWOT analysis and provide knowledge on how to conduct a SWOT analysis. This training activity lasted one day and was held in the GKPS 2 Pematangsiantar Private Vocational School building, which was attended by 15 participants from the Principal, Deputy Principal, Head of Department, Teachers, and Employees. The method used in implementing this activity is a lecture or material delivery and practice/training in conducting a SWOT analysis by taking the case of the GKPS 2 Pematangsiantar Private Vocational School. The results of this training activity showed there was an increase in the knowledge of the participants doing a SWOT analysis, as evidenced by the overall pre-test results from 43.3% to 61.3% of the overall post-test results from participants

Effects of Shape Changing of Morphing Rotary Wing Aircraft on Longitudinal and Lateral Flight
Authors: OKTAY Tuğrul , ÖZEN Enes
Published: August 2022

Unmanned aerial vehicles are aerial robots controlled by commands sent from the ground control station. While fixed-wing aircraft have the advantages of long range and high altitude, they need a runway to create sufficient lift on the wings. The advantage of Rotary Wing Aircraft is that it does not need a runway, it can perform vertical take-off and landing. It can hover. Thanks to these features, it is used in tasks such as surveillance, search and rescue, and reconnaissance. In areas with chemical wastes or in closed environments without risking the human element; Desired tasks can be performed in places such as sewers, caves, and collapsed houses. For this, there is a flight control computer and software on the aircraft. Rotary-wing aircraft are more unstable than fixed-wing aircraft. Thanks to the flight controller, its stability and controllability are increased. In this study, a quadcopter, multicopter aircraft structure is used. The variation of the angle between the arms of a quadcopter aircraft and its effects on forward and sideways flight are examined. It is required that the aircraft be symmetrical in the longitudinal and lateral axis in order to cope with the disturbances to which it is exposed in external environments. In closed environments, atmospheric events are replaced by obstacles. One of the desirable features of the aircraft is that it can pass through narrow places. For this, the aircraft must perform a shape change. The change in structure will cause it to change in the dynamic’s equations, causing the rotors to react differently during linear and rotational movements of the aircraft. This study focuses on the system design and control of the aircraft. The geometric features obtained from the aircraft designed in the CATIA program were used in the creation of the mathematical model. The obtained values were created using the MATLAB Simulink program to create a digital twin of the aircraft. When the intersection angle between the arms is 90 degrees, the settling time of the 2-degree pitch angle is 7.48 seconds, and when it is 45 degrees, it is 10.3 seconds.
Contribution of Scientific Production to Air Logistics: A Bibliometric Analysis from the 70s to the Present
Authors: COŞKUN Artuğ Eren , ALPAR Mustafa Özer , ERTURGUT Ramazan
Published: August 2022

With increased performance expectations based on speed and agility in logistics flow and supply chain processes, air logistics has gained popularity as a research area. Although more and more papers are published each year on this subject, to the best of our knowledge, a comprehensive bibliometric academic publication review has not been presented so far to contribute to the intellectual structure of the literature. Therefore, this study aims to investigate the last 5 decades’ intellectual basis of air logistics studies that can be evaluated in the field of social sciences. For this purpose, a total of 398 articles have been accessed to be used in the bibliometric analysis of studies published in the literature of air logistics, and these data have been provided from the Core Collection Database of Web of Science (WOS). The research data consists of articles published in English in the WOS database between 1971 and 2019. Books and papers published in all other languages were not included in the research. The Bibliometrix (Biblioshiny) package of the statistical software program R was used for the analysis and visualization of the data. Research findings indicate that air logistics research has increased greatly, especially in the last 10 years. The most productive countries are the United States, China, and Canada, respectively, while the most published journal is the Journal of Air Transport Management, which has continued to increase its number of publications since 1995. Although there are no tear restrictions in this study, the number of publications on air logistics in the field of social sciences is still insufficient.
Numerical modeling of steel fiber reinforced concrete spallation exposed to medium loading rate
Authors: Ammar BabikerAamir Dean  , Ebtihag Abu-Elgasim  , Taghried Abdel-Magid
Published: August 2022

Properties of unreinforced concrete and cement-based matrix are well understood. One of the issues with the cement-based matrix is its inherently brittle failure when exposed to loading. As such, steel fibers were proposed to enhance the ductility of cement-based and concrete materials. Ever since, Fiber-Reinforced Concrete (FRC) has become a commonly used building material in many construction activities such as bridges, airport pavements, shotcrete, and many others. According to previous research, the addition of steel fibers, typically from 20 to 50 kg/m3 into the conventional concrete, can significantly enhance many of the desired engineering properties of hardened concrete such as flexural strength, tensile strength, micro-cracks as well as splitting. This research presents a study aimed to numerically investigate the influence of steel fibers on the dynamic behavior of Plain Concrete (PC) exposed the tensile loading at medium strain-rate. The influence of steel fibers is investigated using different fiber volume fractions ranging from 0.0 to 4.5%. The Modified Split-Hopkinson-Bar (MSHB) apparatus is employed to investigate the dynamic tensile behavior of PC and Steel Fiber-Reinforced Concrete (SFRC). Validation of the finite element model and constitutive material behavior is carried out with the comparison of computed and measured experimental pull-back velocities of the specimen’s free end. The results showed that impact properties of steel fibers exhibit significant improvement in the toughness and the dynamic tensile strength of concrete and higher fiber volume fraction is more effective in enhancing the mechanical properties of SFRC composite.
Biomarkers of lead in occupationally exposed persons in Gurara and Suleja areas, Niger State, Nigeria
Authors: ALIYU HARUNA SANI  , UMAR SIDI JAMILU
Published: August 2022

Human exposure to lead could pose serious health challenges, especially among occupationally-exposed workers. Though several toxicological studies have been carried out on toxic lead exposure in humans regarding their levels, reactions and disease conditions; dearth data exists in terms of correlation of lead levels with their exposure markers and subsequent manifested disease conditions. This study therefore aims to investigate the association between lead exposure and specific biomarkers used in monitoring lead levels in some occupationally exposed individuals and comparing the values with non-exposed individuals. A total of 116 subjects (72 occupationally exposed and 44 non-exposed subjects) within the age range of 17– 50 years were studied in a cross-sectional study conducted between August 2021 and November 2021 in Gurara and Suleja areas, in Niger state, Nigeria. Blood lead levels, hepato-renal indices and hematological parameters were analyzed using atomic absorption spectrophotometer (AAS) and abacus 380 analyzer, respectively. The mean blood levels of lead were 26.8±5.4 μg/dL in occupationally-exposed subjects, while in non-exposed subject’s 3.7±2.1 μg/dL. The results showed that occupational exposure increases the blood level of lead, implicating hematological variables and elevating specific hepato-renal indices which consequently increase the health risk of occupationally exposed individuals. Therefore, taking note of other body burdens, the synergistic adoption of these indicative biomarker tests could be used to give an implicative assessment on lead exposure and toxicity.

Published: August 2022

The economic progress of recent years has contributed to the fact that both the quality of products and services offered and ISO standardization have become priority criterion that determines the success of manufacturing enterprises. Therefore, the monitoring and supervision of processes carried out in manufacturing companies is a key issue. These aspects support the achievement of key economic and quality objectives. The paper presents the results of a study on manufacturing enterprises in the context of process monitoring maturity. The research objective of the study was to determine the level of maturity in the use of process monitoring techniques and methods in manufacturing enterprises. The subject of the research were the techniques and methods used by the surveyed enterprises in such areas as: production management, machinery park management, warehouse management, transport management, inventory and supply management and IT tools. In order to determine the level of maturity, the author’s model was used, according to which the level of maturity of a manufacturing enterprise in the area of process monitoring depends on the instrumentation that is used in it.

A wide range of elastomers allows to manufacture products that meet high demands of consumers. They are prepared from a mixture of several rubbers, rubber chemicals, additives and reinforcing materials (fibres), which allows you to obtain the desired properties of the products. The other components of rubber compounds are fillers, carbon blacks and plasticizers. Rubber chemicals supplement the mixture in small quantities of related products, which affect vulcanization and regulate their properties, so they have an irreplaceable role in the preparation of rubber products. The aim of experimental part is to assess the properties of the degradation environment on samples of rubber composites to change their properties. The result of the performed mechanical tests to evaluate and compare the obtained values of mechanical properties of rubber compounds and to predict the possibility of biological degradation of the tested material.

The changes brought about by the spread of COVID-19 require from entrepreneurs a new approach to the way they manage their businesses. Accounting offices are also facing a major challenge these days. In addition to the constant changes in tax regulations and the implementation of many new provisions concerning anti-crisis shields, the way of customer service in accounting offices has also changed as they had to adapt to the new reality. The aim of this article is to present the importance of improving the quality of accounting services in the pandemic era. The first part of the paper includes the scope of services and theoretical aspects of customer service in accounting offices in the era of SARS-CoV-2 as well as the characteristics of the concept of quality. Subsequently, the results of an anonymous survey conducted among entrepreneurs who are clients of accounting offices are presented, which contributed to the formulation of conclusions on the significance of customer service quality in accounting offices. The article highlights the significant changes in the way tasks are performed in accounting firms and financial departments. Among the modern methods of providing accounting services, two have been selected which (according to the respondents) will significantly effect on the service providing quality (in particular by limiting personal contact of contractors).

Suomenoppijoiden käsityksiä kolmaspersoonaisten pronominien käytöstä ja puhuttelusta
Authors: Jokela Hanna

My study is a survey that examines how Finnish as a second language speakers understand the use of Finnish pronouns and how to address people. I focus on the informants’ experiences and perspectives with the allocation of the Finnish third-person singular pronouns hän (‘he’ and ‘she’) and se (‘it’) and second-person singular sinä (familiar ‘you’) and plural te used as singular (formal ‘you’). I examine these issues particularly in light of previous studies carried out on addressing and variation. The informants in this study encompass a group of immigrants with an academic background. The survey shows that these informants can identify factors and situational variation that lead to pronoun choice as well as using the familiar or formal ‘you’. In examining hän and se, the differentiation between colloquial Finnish practices and the norms of standard Finnish is an important aspect. In particular, se is seen as confusing, as it is colloquially used for human beings and standardly for animals, while hän could also be used for household pets. The informants’ experiences with sinä and te show that they perceive their set of politeness norms used for addressing as one that often differs from that of a Finn.My materials provide preliminary indications of the fact that the approach non-native speakers take on the deviation from standard Finnish norms and on situational variation may differ from that of native Finnish speakers. What is interesting is that identifying variation does not necessarily change one’s own approach or way of speaking.

Few children in low-income countries receive appropriate treatment for diarrhea and pneumonia, which are the leading causes of under-five child deaths. Community-based interventions can increase the uptake of specific treatments for diarrhea and pneumonia, potentially leading to a decrease in under five child mortality.
Does home-based HIV Voluntary Counselling and Testing (VCT) improve the uptake of HIV testing?
Authors:   Swiss Tropical and Public Health Institute, Switzerland, Steinmann Peter
Published: August 2022

Knowledge about people’s HIV status is important for developing effective HIV prevention, treatment and care strategies. HIV testing is typically performed using Voluntary Counselling and Testing (VCT) at dedicated VCT centres or healthcare facilities. However, many people lack access to VCT sites or prefer not to use them. One strategy to boost the uptake of HIV testing is to use trained counsellors or lay health workers to provide VCT in patients’ homes.

In the last three decades, rates of neonatal mortality in low-income countries have declined much more slowly than the rates of infant and maternal mortality. A significant proportion of these deaths could potentially be addressed by community-based intervention packages, which are defined as delivering more than one intervention via different sets of strategies that include additional training of outreach workers, building community-support, community mobilization, antenatal and postnatal home visitation, training of traditional birth attendants, antenatal and delivery home visitation, and home-based neonatal care and treatment; usually supplemented by strengthening linkages with local health systems.
