The literature on sustainable tourism is scant, particularly in the least developed countries. Very few studies touch upon the concept and no holistic theoretical or conceptual frameworks around the idea of sustainable tourism have been formulated. This study aims at exploring the role of tour operators in developing sustainable tourism in Pakistan and how the tour operators (TOs) conceive their r

Ett ekologisk, ekonomiskt och socialt hållbart nyttjande av jordens resurser är en viktig förutsättning för en hållbar samhällsutveckling och inte minst för vår förmåga att tackla och anpassa oss till aktuella och framtida utmaningar, såsom klimatförändringar eller pandemier. En av de stora frågorna kopplat till detta är markanvändningen: Hur vi ska använda våra begränsade markresurser, så att vi

This article addresses issues surrounding the social construction of internet addiction, focusing on conceptualisations of reality, escape, hope, and time. Drawing on a critical realist account of semiosis, the framing of internet addiction in China is analysed using the documentary film Web Junkie as an empirical pivot and point of departure. A contextual overview of relations, interests, and ten

Air pollution causes premature mortality and morbidity globally, but these adverse health effects occur over proportionately in low-and middle-income countries. Lack of both air pollution data and knowledge of its spatial distribution in African countries have been suggested to lead to an underestimation of health effects from air pollution. This study aims to measure nitrogen oxides (NOx), as wel

While there is much debate on transformative change among academics and policymakers, the discussion on how to govern such change is still in its infancy. This article argues that transformative governance is needed to enable the transformative change necessary for achieving global sustainability goals. Based on a literature review, the article unpacks this concept of transformative governance. It

This article studies the import of East German films by Swedish public service broadcaster Sveriges Radio, and their reception in the Swedish public sphere. While few GDR films reached theatrical distribution, Swedish television imported and broadcasted over 30 productions by the state-owned film studio DEFA during the 1970s and 1980s, making this the primary distribution window for East German fi

Solar radiation plays a pivotal role in the energy balance at the Earth's surface, evaporation, snow melting, water requirements of plants, and hydrological control of catchments. In this work, performance of ERA-Interim (a reanalysis dataset) was examined to estimate solar radiation at Ahvaz, BandarAbbas, and Kermanshah weather stations representing the even spatial distribution over Iran using e

The annual 14C data in tree rings is an outstanding proxy for uncovering extreme solar energetic particle (SEP) events in the past. Signatures of extreme SEP events have been reported in 774/775 CE, 992/993 CE, and ∼660 BCE. Here, we report another rapid increase of 14C concentration in tree rings from California, Switzerland, and Finland around 5410 BCE. These 14C data series show a significant i

Traumatic brain injury (TBI) is an established risk factor for neurodegenerative disorders and dementias. Epigenetic modifications, such as DNA methylation, may alter the expression of genes without altering the DNA sequence in response to environmental factors. We hypothesized that DNA methylation changes may occur in the injured human brain and be implicated in the neurodegenerative aftermath of

Blocked isocyanate-terminated, bioactive bis-indole based polyurethane dendrimers of generation G0 – G3 were subjected to urethane interchange reaction with poly(ethylene glycol) monomethyl ether; the reactions yielded corresponding PEGylated dendrimers. The structures of the PEGylated dendrimers were confirmed using spectroscopic and SEC-MALS techniques. The PDI of the polymers were found between

The meteoritic material falling on Earth is believed to derive from large break-up or cratering events in the asteroid belt. The flux of extraterrestrial material would then vary in accordance with the timing of such asteroid family-forming events. In order to validate this, we investigated marine sediments representing 15 time-windows in the Phanerozoic for content of micrometeoritic relict chrom
