Abstract This paper introduces the concept of emotional distress as a means of measuring the direct experience of inadequate access to drinking water in a small town in Ethiopia under the UNICEF-Government of Ethiopia urban ONEWASH plus programme. The paper explores a new perspective on the relationship between water technologies, water services, household socio-economic characteristics (as predictors) and mental health in its broad definition. Results indicate that water-related emotional distress is predominantly associated with the ‘cost of water’ and the ‘size of household’. Quantity of water, reliability of the preferred source and accessibility were not significant predictors to emotional distress. Whether the household accessed a pipe into a compound or another improved source was not a significant predictor either. The safely managed target in the Sustainable Development Goal (SDG) 6.1 focuses on the affordability, accessibility and safety of water but does not explore the relation between cost and water-related emotional distress. This evidence offers a complementary approach to the ‘affordability of water services’ as it looks beyond the mere financial implications of water costs.

This paper reports a comparative case study on the use of different softening products for bed linen fabrics, specifically regarding the sewability of the fabrics. The market offers a wide variety of commercial formulations of softeners for this purpose, but the composition and price varies considerably. This work was aimed to assess the relationship between the cost and effectiveness of different softener formulations in home textiles finishing. Objectively, the effect of different softeners and their concentrations on sewability of the fabrics was studied. Non-ionic polyethylene dispersions and a cationic silicone softener micro-emulsion in different concentrations and combinations were considered in this investigation. It was found that a combination of silicone and polyethylene based softeners presents the most interesting cost/performance behavior.

Our study proposes a Romanian national perspective of the gender–sustainability paradigm in higher education under the Sustainable Development Goal 5 (SDG5) approach. The starting point is the interlinkage of the two concepts, gender parity and sustainability, depicted on a fundamental societal domain. Data collection was completed following a census approach, resulting in staffing data on 47 Romanian state-owned universities. Data collected envisaged the tenure teaching staff, divided into two gender groups; the count was focused on executive roles and collective managerial elected bodies for the 2015–2019 mandate. The gender situation was analyzed quantitatively by the number of teaching staff, their gender structure, and their representation in the executive functions and collective decision-making bodies. We calculated gender indexes and used statistical correlation coefficients to explain the relations between the different categories of personnel and their influence on establishing the management structures. The results of the gender configuration analysis were further associated with the latest national meta-ranking of Romanian universities. Our findings show that Romanian universities demonstrate sustainability under SDG5 through their institutional capacity to use either feminine majorities or a statistically detected pro-female voting propensity in order to construct optimally gendered management structures through vote only.

The development of tourism leads to changes in land-use demands and patterns, which are complex and dynamic, in tourist cities. Functional differences in land use produce different travel needs and have different impacts on traffic, especially on tourism. This paper explores the relationship between tourism land use and tourism traffic. Taking Xiamen Island as an example, using multivariable linear regression models, tourism land use is divided into accommodation land use, shopping land use and restaurant land use as the independent variables of the model; and the origin-destination (OD) density of traffic analysis zones (TAZs) during National Day in 2018 (October 1 to 5) is chosen as the dependent variable. To compare the different impacts between tourism land use and tourism traffic during the tourism and non-tourism periods, the non-tourism period (March 11 to 15) is further studied. The results show the following: (1) Xiamen, as a tourism city, has not only regular traffic but also tourism traffic, and traffic during the tourism period is totally different than that in the non-tourism period. (2) Tourism land use has a considerable impact on both tourism traffic and non-tourism traffic, but the impact is greater during the tourism period than the non-tourism period. (3) In the morning peak hour of both the tourism period and the non-tourism period, accommodation land use shows prominent effects on traffic. In the evening peak hour, shopping land use significantly impacts traffic. The study provides a basis for urban tourism land use adjustment to achieve the sustainable development of tourism traffic.

Stability Of Plant Communities

The relationship between diversity and stability is a classic issue in ecology, but no general consensus has been achieved. To address this relationship, a field survey of a forest in Northeast China was conducted. The temporary stability was defined from the perspective of community characteristics. The results showed that communities with the highest temporary stability value were characterized by a single dominant species. A significant linear relationship with a low R2 value was observed between temporary stability and tree richness. When dominant and non-dominant tree species were studied, no significant linear relationship was obtained between temporary stability and non-dominant tree richness. However, the relationship between temporary stability and dominant tree richness was significant with a high R2 value, and the temporary stability decreased with increasing dominant tree richness. This study demonstrates that dominant tree richness is closely related to temporary stability, and temporary stability can serve as a stability indicator. The results provide a new perspective for understanding stability and additional information for revealing the relationship between diversity and stability in forest ecosystems.

General Collective Intelligence (GCI) are software platforms that organize groups into a single collective intelligence with general problem solving ability. In doing so a GCI has the potential to give groups vastly more ability to address collective challenges such as the SDGs. A GCI is a significant infrastructure investment. The Collective Intelligence based Program to Accelerate Achievement of the Sustainable Development Goals (CIPAA-SDGs) however is designed to implement a GCI in phases so that the cost to any single project is far outweighed by the potential benefits. The phasing of that GCI development in the CIPAA-SDGs program design is used here as a case study for collectively intelligent program design.

The Cost

The generation of energy from renewable sources is a fundamental aspect for the sustainable development of society, and several energy sources such as solar, biomass, biogas, and wind must be used to the maximum to meet existing needs. In Chile, there are villages that are off-grid. A real case study is presented in this research. To meet the needs of this village we have proposed a mathematical optimization model using a CPLEX optimizer to generate the necessary energy power while minimizing the cost of energy (COE). In this study, different scenarios have been evaluated with respect to the existing energy availabilities, for example, in different periods of the year, demonstrated in terms of economic costs, the viability of resources such as biomass and biogas, and the viability of the energy production of wind power given the associated high costs. Finally, the effect of the use of renewable energy in consideration of CO2 emissions is studied in our research.

The Relationship

This is a case study of an undergraduate calculus student's nonstandard conceptions of the real number line. Interviews with the student reveal robust conceptions of the real number line that include infinitesimal and infinite quantities and distances. Similarities between these conceptions and those of G. W. Leibniz are discussed and illuminated by the formalization of infinitesimals in A. Robinson's nonstandard analysis. These similarities suggest that these student conceptions are not mere misconceptions, but are nonstandard conceptions, pieces of knowledge that could be built into a system of real numbers proven to be as mathematically consistent and powerful as the standard system. This provides a new perspective on students' “struggles” with the real numbers, and adds to the discussion about the relationship between student conceptions and historical conceptions by focusing on mechanisms for maintaining cognitive and mathematical consistency.
