Continuing population and consumption growth will mean that the global demand for food will increase for at least another 40 years. Growing competition for land, water, and energy, in addition to the overexploitation of fisheries, will affect our ability to produce food, as will the urgent requirement to reduce the impact of the food system on the environment. The effects of climate change are ...

Open Educational Resources (OERs) have gained increased attention for their potential to provide equitable and accessible educational facilities for people worldwide. Obviating demographic, economic, and geographic educational boundaries can be the OERs slogan. Realization of this promise is an inevitable target of eLearning, thus offering education new challenges. In this observation paper, we...

An L(2, 1)-labeling of a graph G is equitable if the number of elements in any two color classes differ by at most one. The equitable L(2, 1)-labeling number λe(G) of G is the smallest integer k such that G has an equitable L(2, 1)-labeling. Sierpiński graphs S(n, k) generalize the Tower of Hanoi graphs—the graph S(n, 3) is isomorphic to the graph of the Tower of Hanoi with n disks. In this pap...

In line with the policy objectives of the United Nations Sustainable Development Goals, this commentary seeks to examine the extent to which provisions of international health research guidance promote capacity building and equitable partnerships in global health research. Our evaluation finds that governance of collaborative research partnerships, and in particular capacity building, in resour...

We construct a 1-factorization of the complement Σm of the linear Hamming code of length m = mr = 2 r − 1 in the m-cube Qm, for r ≥ 2, having the following equitable property: its component 1-factors intersect each Cayley parallel 1-factor of Qm at a constant number of edges, (namely 2r edges). In the way to that construction, we find an equitable mr−1-factorization of Σm formed by two factors ...

In this note, we give a complete solution of the existence of orthogonal generalized equitable rectangles, which was raised as an open problem in [4].

The reload cost refers to the cost that occurs along a path on an edge-colored graph when it traverses an internal vertex between two edges of different colors. Galbiati et al. [1] introduced the Minimum Reload Cost Cycle Cover problem, which is to find a set of vertex-disjoint cycles spanning all vertices with minimum reload cost. They proved that this problem is strongly NP-hard and not appro...

At the turn of the XXI century, the emergence of new forms of work organization are transforming what had become standard forms of work arrangement in industrialized countries. In this new work environment, new firms, new types of workers and new risk factors are powerfully emerging. Contrary to common belief, we argue that emergent occupational health hazards should not be approached only as "...

By respecting nature’s limits and investing in nature’s wealth, we can protect and enhance the environment’s ability to sustain human wellbeing. But how humans interact with nature is intimately tied to how we interact with each other. Those who are relatively powerful and wealthy typically gain disproportionate benefits from the economic activities that degrade the environment, while those who...

Measures of sexual wellbeing and positive aspects of sexuality in the World Health Organization definition for sexual health are rarely studied and remain poorly understood, especially among adolescents in Sub-Saharan Africa. The objective of this study was to assess sexual wellbeing in its broad sense-i.e., body image, self-esteem, and gender equitable norms-and associated factors in young ado...
