Tourism and Technology: Revisiting the Experiences of Women Travelling Alone

This paper revisits some of the key concepts I used in my original research into solo female tourists in the 1990s to explore how technology impacts upon, and influences, the experiences of women travelling alone. The paper reviews the market for solo female travel since the 1990s and the ways in which technology is helping to shape its growth. It also considers the influence of technology on the experiences of travel with particular regard to its impact on the performance of tourists, and surveillance and security in tourism

HOW MUCH IS ENOUGH?: CONSTRAINTS OF POPULATION,TEMPERATURE RISE, POLITICS AND ECONOMICS: A CONCEPT PAPER.

How Much Is Enough? Can be thought of generally in terms of sustainability. This paper broadly adopts that approach but also mentions The Sufficiency Economy (SE) Thailand which is derived from Buddhist philosophy and which promotes the idea that we should open our mind and implement practices to the needs (not wants) of all people and that those needs be modest i.e. sufficient.  Proponents of this sufficiency economy were EF Schumacher (19111977) of the UK and King Bhumibol Adulyadejj (Rama 9 (reign from 05-05-1950 to 13-102016) in Thailand.  This concept paper considers major factors influencing the Sufficiency Economy worldwide (not only for Thailand) namely: population (whether it involves growth, stability or decline); changes to global climate; preferred political system/s; preferred economic system/s; preferred standard-of-living; employment opportunity

In preeclampsia, maternal third trimester subcutaneous adipocyte lipolysis is more resistant to suppression by insulin than in healthy pregnancy

Obesity increases preeclampsia risk, and maternal dyslipidemia may result from exaggerated adipocyte lipolysis. We compared adipocyte function in preeclampsia with healthy pregnancy to establish whether there is increased lipolysis. Subcutaneous and visceral adipose tissue biopsies were collected at caesarean section from healthy (n=31) and preeclampsia (n=13) mothers. Lipolysis in response to isoproterenol (200 nmol/L) and insulin (10 nmol/L) was assessed. In healthy pregnancy, subcutaneous adipocytes had higher diameter than visceral adipocytes (<i>P</i><0.001). Subcutaneous and visceral adipocyte mean diameter in preeclampsia was similar to that in healthy pregnant controls, but cell distribution was shifted toward smaller cell diameter in preeclampsia. Total lipolysis rates under all conditions were lower in healthy visceral than subcutaneous adipocytes but did not differ after normalization for cell diameter. Visceral adipocyte insulin sensitivity was lower than subcutaneous in healthy pregnancy and inversely correlated with plasma triglyceride (<i>r</i>=−0.50; <i>P</i>=0.004). Visceral adipose tissue had lower <i>ADRB3, LPL,</i> and leptin and higher insulin receptor messenger RNA expression than subcutaneous adipose tissue. There was no difference in subcutaneous adipocyte lipolysis rates between preeclampsia and healthy controls, but subcutaneous adipocytes had lower sensitivity to insulin in preeclampsia, independent of cell diameter (<i>P</i><0.05). In preeclampsia, visceral adipose tissue had higher <i>LPL</i> messenger RNA expression than subcutaneous. In conclusion, in healthy pregnancy, the larger total mass of subcutaneous adipose tissue may release more fatty acids into the circulation than visceral adipose tissue. Reduced insulin suppression of subcutaneous adipocyte lipolysis may increase the burden of plasma fatty acids that the mother has to process in preeclampsia

Semantic systems in closely related languages

In each semantic domain studied to date, there is considerable variation in how meanings are expressed across languages. But are some semantic domains more likely to show variation than others? Is the domain of space more or less variable in its expression than other semantic domains, such as containers, body parts, or colours? According to many linguists, the meanings expressed in grammaticised expressions, such as (spatial) adpositions, are more likely to be similar across languages than meanings expressed in open class lexical items. On the other hand, some psychologists predict there ought to be more variation across languages in the meanings of adpositions, than in the meanings of nouns. This is because relational categories, such as those expressed as adpositions, are said to be constructed by language; whereas object categories expressed as nouns are predicted to be “given by the world”. We tested these hypotheses by comparing the semantic systems of closely related languages. Previous cross-linguistic studies emphasise the importance of studying diverse languages, but we argue that a focus on closely related languages is advantageous because domains can be compared in a culturally- and historically-informed manner. Thus we collected data from 12 Germanic languages. Naming data were collected from at least 20 speakers of each language for containers, body-parts, colours, and spatial relations. We found the semantic domains of colour and body-parts were the most similar across languages. Containers showed some variation, but spatial relations expressed in adpositions showed the most variation. The results are inconsistent with the view expressed by most linguists. Instead, we find meanings expressed in grammaticised meanings are more variable than meanings in open class lexical items

Visceral adipose tissue activated macrophage content and inflammatory adipokine secretion is higher in pre-eclampsia than in healthy pregnancy

Obesity increases preeclampsia risk. Adipose tissue inflammation may contribute to the clinical syndrome of pre-eclampsia. We compared adipose tissue macrophage infiltration and release of pro-inflammatory adipokines in pre-eclampsia and healthy pregnancy. Subcutaneous and visceral adipose tissue biopsies were collected from healthy (n=13) and preeclampsia (n=13) mothers. Basal and lipopolysaccharide stimulated adipocyte TNFα, IL-6, CCL-2 and CRP release was measured. Adipose tissue cell densities of activated (cfms(+)) and total (CD68(+)) macrophages were determined. In pre-eclampsia only, visceral adipose tissue TNFα release was increased after lipopolysaccharide stimulation (57 [76] vs 81 [97] pg/mL/ug DNA, p=0.030). Basal TNFα release was negatively correlated insulin sensitivity of visceral adipocytes (r=-0.61, p=0.030) in pre-eclampsia. Visceral adipocyte IL-6 release was increased after lipopolysaccharide stimulation in pre-eclampsia only (566 [696] vs 852 [914] pg/mL/ugDNA, p=0.019). Visceral adipocyte CCL-2 basal (67 [61] vs 187 [219] pg/mL/ugDNA, p=0.049) and stimulated (46 [46] vs 224 [271] pg/mL/ugDNA, p=0.003) release was greater than in subcutaneous adipocytes in pre-eclampsia only. In pre-eclampsia, median TNF mRNA expression in visceral adipose tissue was higher than controls (1.94 [1.13-4.14] vs 0.8 [0.00-1.27] TNF / PPIA ratio, p=0.006). In visceral adipose tissue, CSF1R (a marker of activated macrophages) mRNA expression (24.8[11.0] vs 51.0[29.9] CSF1R/PPIA ratio, p=0.011) and activated (cfms+) macrophage count (6.7[2.6] vs 15.2[8.8] % cfms+/adipocyte, p=0.031) were higher in pre-eclampsia than in controls. In conclusion, our study demonstrates dysregulation of inflammatory pathways predominantly in visceral adipose tissue in pre-eclampsia. Inflammation of visceral adipose tissue may mediate many of the adverse metabolic effects associated with pre-eclampsia

The semantics and morphology of household container names in Icelandic and Dutch

In this paper, we report an experiment on the naming of household containers in Dutch and Icelandic carried out as part of the Evolution of Semantic Systems project (EoSS; Majid et al., 2011). This naming experiment allows us to support and elaborate on a hypothesis by Malt et al. (2003) that productive morphology in the naming domain can have an influence on boundary placement within the extensional space. Specifically, we demonstrate that the Dutch diminutive -(t)je favours a cut between small items versus others, whereas Icelandic, which does not use the diminutive in this domain, favours a cut between large items and others. This is not a typological effect, as Dutch and Icelandic are both Germanic languages and both have diminutive morphology available in principle. We find no evidence that the diminutive produces a proliferation of terms and/or fine-grained nesting within the extensional domain. Rather, the Dutch diminutive favours a more even distribution of terms across the space whereas Icelandic favours broad inclusive terms with a number of narrower specialist terms. Further, the extensional space defined by the diminutive is not associated with its own clear prototypical exemplar. Using evidence from compounding and modification, we also consider which semantic features are prominent in differentiating categories within the domain. By far the most prominent in both languages is the inferred contents of the container. Other than contents, however, the languages differ in the range and prominence of features such as intended usage or material of composition. Our results demonstrate that in order to understand the processes that produce semantic divisions of basic object classes, we should consider fine-grained analyses of closely related languages alongside analyses of typologically different languages

Comparative phylogenetic methods and the study of pattern and process in kinship

Anthropology began by comparing aspects of kinship across cultures, while linguists interested in semantic domains such as kinship necessarily compare across languages. In this chapter I show how phylogenetic comparative methods from evolutionary biology can be used to study evolutionary processes relating to kinship and kinship terminologies across language and culture

Pama-Nyungan grandparent systems change with grandchildren, but not cross-cousin terms or social norms

Kinship is a fundamental and universal aspect of the structure of human society. The kinship category of ‘grandparents’ is socially salient, due to grandparents’ investment in the care of the grandchildren as well as to older generations’ control of wealth and cultural knowledge, but the evolutionary dynamics of grandparent terms has yet to be studied in a phylogenetically explicit context. Here, we present the first phylogenetic comparative study of grandparent terms by investigating 134 languages in Pama-Nyungan, an Australian family of hunter-gatherer languages. We infer that proto-Pama-Nyungan had, with high certainty, four separate terms for grandparents. This state then shifted into either a two-term system that distinguishes the genders of the grandparents or a three-term system that merges the ‘parallel’ grandparents, which could then transition into a different three-term system that merges the ‘cross’ grandparents. We find no support for the co-evolution of these systems with either community marriage organisation or post-marital residence. We find some evidence for the correlation of grandparent and grandchild terms, but no support for the correlation of grandparent and cross-cousin terms, suggesting that grandparents and grandchildren potentially form a single lexical category but that the entire kinship system does not necessarily change synchronously
