Proxemics Beyond Proximity: Designing for Flexible Social Interaction Through Cross-Device Interaction

Cross-device interactions enable ad hoc sharing of content and control in co-located collaboration. Cross-device research often draws from proxemics theory for designing interactions based on detection of spatial relations such as distance and orientation between people and devices. However, detection of human-human or human-device proximity also constrains flexibility in co-located social interaction. We suggest a proxemics-based approach to designing flexible cross-device interactions. From observations in a field study, we articulate how co-located sharing practices are shaped by the interplay between everyday mobile devices and the physical environment. Based on these insights, we present three cross-device prototypes as proofs-of-concept, demonstrating three design sensitivities for considering proxemics beyond proximity; incorporating features in the environment, enabling flexibility in interpersonal distance and orientation, and providing multiple alternative action possibilities. Drawing from characteristics of our prototypes, we discuss concrete proposals for designing cross-device interactions to enable flexible social interaction.
Neonatal Determinants of Mothers’ Affective Involvement in Newly Delivered Cameroonian Women

Background: Emotional instability represents a common psychological impairment experienced by newly delivered women, susceptible to impact mothers’ affective involvement and hence mother-infant bonding. It may occur as early as during the first two weeks of early postpartum, manifesting firstly with the baby blues also known as postpartum or maternity blues, and secondly with postpartum depression or psychosis. Mother-infant bonding as defined in this study refers to the emotional attachment that normally exist between a mother and her newly born infant. Factors susceptible to impact mother-infant bonding may be maternal, environmental, neonatal, or a combination of all, with possible repercussions on the neonate’s neurological and psycho-affective development. Objective: We aimed to identify and assess neonatal determinants of mothers’ affective involvement few days after delivery in Cameroonian women. Method: A case-control study was carried out over a period of four months in 2015, in two teaching hospitals of Yaounde, Cameroon among 321 newly delivered women of which 107 had been diagnosed with emotional instability (the cases), and 214 emotionally stable women (the controls). Results: Neonatal factors associated with mothers’ emotional swings also known as the baby blues were babies presenting health problems (OR=4.33; p<0.001), mothers’ difficulties in taking care of the baby (OR=7.65; p<0.001), having given birth to a baby of female sex (OR=1.66; p=0.033). Conclusion: Emotional instability and mood swings causing affective impairments in mothers few days after delivery may be associated with a number of neonatal factors which account for its onset. There exists a susceptibility to the alteration of mother-infant bonding which can resound on neonatal neurological and psycho-affective development. This may be prevented by optimal preparation for maternity including baby care practices, perinatal counselling, mothers’ assistance, and encouraged breastfeeding.
Correlation between persistent free radicals of biochar and bio-oil yield at different pyrolysis temperatures

Biomass pyrolysis technology has important developmental prospects for biofuels and chemicals. Biochar as one of main pyrolysis products has excellent performance in soil improvement and adsorption of harmful elements. The environmentally persistent free radicals (EPFRs) in corn stalk powder and biochar obtained by pyrolysis at different temperatures were tested by electronic paramagnetic resonance spectrometry. After pyrolysis treatment, the biochar had a large number of stable free radicals. With increased pyrolysis temperature, the peak width of the free radicals signal in biochar decreased remarkably, and the widest peak of free radicals signal in biochar was presented at 450 °C, which was 0.69×10-4 T. The g-factor of free radicals in biochar decreased continuously as the temperature increased, while the peak height of free radicals first increased and then decreased. The peak height at 600 °C was only 23.8% of the peak height at 500 °C. The concentration of EPFRs in biochar increased with the increase of temperature from 450 °C to 500 °C, while it decreased at higher temperature (>500 °C). This phenomenon was similar to the trend of bio-oil collection efficiency. The experimental results showed a correlation between EPFRs of biochar and bio-oil yield at different pyrolysis temperatures.
Influence of Ni additions and age-hardening treatment on the corrosion resistance of Al-Cu-Si alloy

The quest for materials with high strength, toughness, light weight, cost effectiveness and good corrosion resistance is one of the major challenges facing materials engineers. Al-Cu-Si alloys have a combination of all these properties except corrosion resistance. In this work, the effects of Ni addition and age-hardening treatment on the corrosion resistance of the alloy were investigated. The results obtained from both gravimetric and linear polarization established that corrosion resistance of the alloy was enhanced by Ni addition and thermal treatment. The reason might be due to the formation of intermetallics such as NiAl3 and Ni3Si, which passivate easily to form oxides that protect the alloy from further corrosion; and also the enveloping of the cathodic intermetallics by the α-matrix—a process called shingling may be responsible for improvement in the corrosion resistance of the alloy.
Consumers' Price Beliefs, Central Bank Communication, and Inflation Dynamics

Many developed economies in recent years have been characterized by a tight labor market and a low inflation environment, a phenomenon referred to as "missing inflation. " To explain this phenomenon, we develop a dispersed information model in which consumers' search for cheaper prices affects firms' pricing behavior. The model shows that firms are reluctant to pass through cost increases because they fear a disproportionate decline in their sales. A history of low and stable inflation amplifies this effect by decreasing consumers' inflation beliefs. In this case, enhancement of the central bank's communication regarding its inflation target more firmly anchors consumers' inflation beliefs and makes the Phillips curve flatter, while enhancement of the central bank's communication about the current aggregate price level has the opposite effect.
Influence of Biofertilizers on Growth and Leaf Mineral Content in Peach Transplants

This study was conducted in the Department of Biology, Al-Rasheed University CollegeBaghdad during 2017 growing season to investigate the influence of some microbial inoculants on 1 year's old trees of “Peento” peach cultivar.

The True Challenges of the Covid-19 Epidemics: The Need for Essential Levels of Care for All

In the last decades, biomedical research and funding supporting it have given a relevant impulse to developing socalled “Personalized Medicine” (PM) and “precision medicine” (the latter definition with emphasis on the usefulness of dividing patients into target groups). This perspective has increased knowledge on how we can predict disease susceptibility and prognosis in a person or how we can define a tailor-made treatment on specific individual immune-genomic characteristics and disease and thus improve the health of such a person [1].
Effect of respiratory vaccine components and route of delivery on weight gain and inflammatory response in suckling beef calves

Two randomized studies of Angus beef calves (n = 110) from 2 Iowa locations were used to determine the effect of vaccine type and route of administration on weight gain and inflammatory response. The first vaccine contained avirulent-live Mannheimia haemolytica (type A1) and Pasteu- rella multocida (type A3), and was administered intranasally (IN group). The second vaccine contained an adjuvanted M. haemolytica (type Al) toxoid and was administered subcutaneously (SC group). Control calves (CON) were given the same volume (2 mL) of sterile saline SC as other calves. At the time of vaccination (day 0), calf body weight (BW) and body temperature (BT) were recorded, and a blood sample was collected for serum haptoglobin analysis. Blood collection and BT measurement were repeated on days 1, 2, and 3 while BW was recorded on days 3 and 21 (location 1) or 24 (location 2) after vaccination. A final BW was taken at weaning at both locations. Changes in BW among calves during the first 3 days after vaccination were not significantly different across treatment groups. At location 1, calves given SC vaccine had a higher average BT compared to IN-vaccinated calves (P < 0.01). Body temperature also tended to be higher in SC-vaccinated calves (P = 0.08) compared to CON calves. At location 2, BT was not different between vaccinated groups, but vaccinated calves had higher BT compared to CON calves (P< 0.01). Over the 21-day trial period at location 1, average daily gain (ADG) in calves given SC vaccine was lower compared to CON calves (P = 0.04). At location 2, ADG was not significantly different among treatments, but IN calves had heavier final weights compared to other treatment groups (P < 0.01). Serum haptoglobin levels were higher for SC calves compared to IN and CON calves on days 1, 2, and 3 following vaccination (P < 0.01). Mean weight gain and ADG from vaccination through weaning tended to be greater (P = 0.06) for IN calves at location 1, but were not different at location 2.
Predictive factors of anxiety level in postpartum period

Background: Pregnancy and delivery are considered as pleasant physiological phenomena. This period, however, sometimes leads to variable mood states in women and makes them more sensitive to psychological stimuli and problems. Objectives: The present study aimed to investigate the role of breastfeeding, type of delivery, contraceptive method, planned pregnancy, and history of infertility on the anxiety level of Iranian women who referred to health centers in Zanjan in the postpartum period. Methods: This cross-sectional study was conducted on 420 women who attended the health care centers in Zanjan city, Iran, during 2018-2019. A checklist including questions about demographic and reproductive information and Beck anxiety inventory were used as the data collection instruments. The data were analyzed using SPSS 21 software through regression analysis. Results: This study found that the history of infertility (β=0.26, t=9.38, p<0.001), unplanned pregnancies (β=0.23, t=-7.00, p<0.001), exclusive breastfeeding (β=-0.47, t=-17.40, p<0.001), mothers’ education (β=0.08, t=-2.89, p<0.001), DMPA (β=0.23, t=6.62, p<0.001), and withdrawal (β=0.17, t=4.59, p<0.001) contraception method were associated with anxiety level. Conclusion: The results of the present study indicate that factors such as breastfeeding, contraceptive methods, infertility history, unplanned pregnancy, and educational level influence women's anxiety level in postpartum period. Identifying and screening women with high levels of anxiety and providing proper counseling to these mothers can help improve their health, infants, families, and community.
Is there value in microinsurance?

1Does microinsurance provide value to clients and their families? In the face of limited evidence of value, the MicroInsurance Centre’s MILK project and the ILO’s Microinsurance Innovation Facility set out to answer this question several years ago, by completing original research and leveraging other evidence from the field. The answer that has emerged from our work – and is supported by new evidence from other studies – is that microinsurance can and often does provide value. However, it does so to varying degrees and in different ways, and sometimes not at all. This brief provides a number of concrete insights into how, when, in what ways and to what extent client value emerges from microinsurance.
HOSTILE AND BENEVOLENT ATTITUDES TOWARDS WOMEN IN ADOLESCENCE

The model of ambivalent sexism (Glick & Fiske, 1996, 1997) has claimed that sexist attitudes towards women include both benevolent and hostile sexism, due to the structure of the traditional male-female roles and relationships, characterised by power difference and also by strong interdependence between the groups. The purpose of our paper is to identify the presence of benevolent and hostile sexist attitudes in adolescence, this period being considered very important for the development of gender beliefs system. The participants were 208 girls and boys, aged between 13 and 18 years, who were administered a version of Ambivalent Sexism Inventory (Glick & Fiske, 1996) and a task designed to assess the content of gender stereotypes. The results showed a higher level of hostile sexist attitudes for the boys in middle and late adolescence, as compared to boys in early adolescence. Furthermore boys presented a higher level of hostile sexism and a lower level of benevolent attitudes than girls. The prejudicial attitudes towards women who are viewed as trying to “usurp” men’s power are not correlated with the benevolent representation of women who conform to their traditional roles. So, in case of our study, the two attitudes are not interrelated within an ambivalent sexist ideology. The findings are discussed in relation to the assumptions of the ambivalent sexism model and to the problem represented by the girls’ approval of benevolent attitudes, which can reinforce hostile sexism.
Coherent J/psi photoproduction at forward rapidity in ultra-peripheral Pb-Pb collisions at root s(NN)=5.02 TeV

The ALICE collaboration performed the ﬁrst rapidity-differential measurement of coherent J /ψ photopro- duction in ultra-peripheral Pb–Pb collisions at a center-of-mass energy √ s NN = 5 . 02 TeV. The J /ψ is detected via its dimuon decay in the forward rapidity region ( − 4 . 0 < y < − 2 . 5) for events where the hadronic activity is required to be minimal. The analysis is based on an event sample corresponding to an integrated luminosity of about 750 μb − 1 . The cross section for coherent J /ψ production is presented in six rapidity bins. The results are compared with theoretical models for coherent J /ψ photoproduction. These comparisons indicate that gluon shadowing effects play a role in the photoproduction process. The ratio of ψ (cid:3) to J /ψ coherent photoproduction cross sections was measured and found to be consistent with that measured for photoproduction off protons.
MEASUREMENT EQUIPMENT FOR MONITORING THE CHANGE OF NH3 CONCENTRATIONS IN THE INDOOR ENVIRONMENT CAUSED BY TIO2 PHOTOCATALYSIS

For monitoring the changes of ammonia and selected greenhouse gases concentrations in the indoor environment (e.g. stable environment) caused by TiO2 photocatalysis was made the measurement equipment. The equipment consists of two identical parts, an area with photocatalytic TiO2 and sources of radiation. Variable connection of these parts can be created a closed or an open path for air flow through the measurement equipment part. These two basic modes of measurement equipment allow measuring continuously the ammonia concentration by gas analyzer. The change of the air velocity passing through the measurement equipment allows managing contact time of air with photocatalytic TiO2. The removable surface with photocatalytic TiO2 is placed inside the equipment. The source of radiation is also removable this allows changing the intensity of the radiation. The experiments with this measurement equipment were performed in a laboratory.
Macular Variability in Children and Adolescents with Metabolic Syndrome: A Cross-sectional Study Examining the Associations with Anthropometric Measurements, Metabolic Parameters and Inflammatory Markers

Objective: Macular damage may be observed in obesity and metabolic syndrome (MetS), a condition which leads to chronic subclinical inflammation and affects most organ systems. To investigate the association between macular variability and anthropometric measurements, metabolic parameters, and inflammatory markers in children and adolescents with MetS. Methods: Two hundred and twenty eyes of 62 obese and 48 healthy children and adolescents were examined. Bilateral macular retinal thickness (MRT) and macular retinal volume (MRV) were measured in all subjects using optical coherence tomography. Associations between mean MRT and mean MRV and age, auxological measurements including body mass index standard deviation scores (BMI-SDS) and waist circumference-SDS (WC-SDS), metabolic parameters and inflammatory parameters including neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio and systemic immune-inflammatory index (SIII) were investigated. Results: No statistically significant difference was observed between the groups in terms of age or sex distribution (p>0.05). Mean MRT (r=-0.326, p=0.007) and MRV (r=-0.303, p=0.007) values in the obese group with MetS decreased as homeostasis model assessment-insulin resistance (HOMA-IR) values increased. SIII values were higher in obese groups, but particularly in obese subject with MetS, compared to the control group (p=0.021). The decrease in mean MRT (r=-0.544, p=0.046) and MRV (r=-0.651, p=0.031) in the obese subjects with MetS was negatively correlated with NLR. Mean MRT and MRV decreased in all obese subjects as SIII increased (p<0.05). Conclusion: This is the first study to show that mean MRT and MRV values decrease as BMI-SDS, WC-SDS and HOMA-IR increase in obese children and adolescents with MetS. NLR and SIII may serve as markers of chronic inflammation in obese children with MetS associated with macular damage.
World Income Inequality 1820-2000 1

The aim of this paper is to present a new dataset of global inequality between 1820 and the present, based on the available historical evidence, and to tentatively analyse some of the results that emerge from these data. The importance of the subject hardly needs to be stressed: the enormous increase of inequality on a global scale is one of the most significant – and worrying features of the development of the world economy in the past 200 years. For this reason, the subject has become one of the most discussed topics in the social sciences; in particular the debate on the measurement and interpretation of recent trends in global inequality – is it still increasing? and why or why not? – has attracted considerable attention (Deininger and Squire, 1996; Jones, 1997; Bourguignon and Morrison, 2002; Milanovic, 2007 for a review of the debate). Economic historians have also intensely discussed the long term trends in the world that lead to the growing income disparities between nations and changed patterns of inequality within nations, although often using other concepts (such as ‘the Great Divergence’). We argue, however, that we lack the historical data to really analyse these patterns of changing global inequality in detail. The one paper that has attempted to do this, Bourguignon and Morrison’s seminal AER 2002 article, is for the period before 1950 largely based on the assumption that income inequality within countries is unchanging. They extrapolate their estimates of income inequality in certain periods to cover much longer time periods, as a result of which, we think, changes in income inequality within countries are clearly underestimated. For large parts of the world the result is that estimates from the post 1914 or even the post 1945 period are used to infer income inequality in the 19 century, and that, in other words, inequality within countries is assumed to have remained constant. For Latin America and Africa B & M rely completely on 20 century data to estimate inequality in the 19 century; for Asia they have in total four historical estimates (in fact often very partial estimates): one for China in 1890, two for Indonesia and one for Japan. The dataset for Europe and North America is somewhat better, but also uses only part of the evidence available. For a large majority of the world’s population, and almost all people living in the ‘developing countries’, their estimates are based on almost no historical evidence, implying that we really cannot rely on their work to analyse the long term patterns of global inequality. Moreover, scholars interested in the question whether
