Business Model Canvas : Merella / Maisarah Abdul Rashid
Full text linkMerella is a hand-free umbrella where make the user’s both hand free such as hikers and travellers. Their hand need to be free because they using all their energy to get to the destination.
Next, our product customer are people who always busy with their phone and for those who needs to carry many things including the umbrella. This is because, Merella can protect both the users and their belongings in the waterproof backpack to make it safer. Students also can use Metrlla since it is affordable to everyon
Do quality ladders rationalise the observed Engel curves?
Full text linkObserved Engel curves are non-monotonic, hence consumption goods may be regarded as luxuries only for ranges of consumer income. This paper rationalises this evidence by postulating that quality of consumption governs the distribution of spending across goods.
We argue that quality upgrading as income increases not only implies that virtually every variety of each good eventually becomes inferior. But also amends the notion of luxury good: a change in income, producing different quality variations across goods, causes heterogeneous spending responses. The resulting Engel curves shapes depend on the rise in quality of each good relative to the average consumption quality improvement. An illustrative simulation shows that the model captures the essential features of the observed Engel curves

Sustainable plans: a review
No full textThis paper illustrates the concept of sustainable equilibrium, reviews its main features and properties, and shows that a time-inconsistency problem might arise, in fact introducing the notion of time-consistent equilibrium. After describing what is peculiar in this idea of sustainable equilibrium, we state an exact definition
Indagini territoriali sugli aspetti insediamentali durante l'età del Bronzo nel contesto del Rio Mannu di Porto Torres: la Valle di Giunche
No full textIn this research, the examined area is localized in the Sassari region and affects a geographical sector of the Mannu hydrographic basin of Portotorres: the Giunche Valley.This area, that includes some municipal territories like Ossi, Tissi, Usini, Florinas, Ittiri, Siligo and Banari, is delimited from natural borders as watersheds that divide the Mannu large basin in more subsystems including, precisely, the sub-basin of Giunche Valley, vasts 50 kmq.The landscape is characterized from a set of undulating hills, sometimes steep and harsh, mainly submitted as in the antiquity as today to the pastoral exploitation and, moderately, to agricultural exploitation.The research aims to understand the settlement dynamics in this region during the Early History.
It was found that Nuragic populations have implanted several permanent establishments (“nuraghi” and villages of huts), on heights and on hills, which carry out a decisive control on natural resources and, above all, on the main stream, that constituted an important source of economy and represented an important communication route for people, artifacts and knowledge.Different community meeting places accompany the seats of life like cultural order (temples) or in funerary environment (Giants tombs).From the analysis is clear that the Giunche Valley wasn’t closed on itself but was in constant contact with the surrounding territories
Mode of transport along the Quality Dimension
No full textAeroplanes are a fast but expensive means of shipping goods, which allow producers to respond quickly to favourable demand realisations and to limit the risk of shipping unprofitably large quantities during low demand periods while substantially raising the transportation cost relative to ocean cargoes. We explore the role of heterogeneous income elasticity of demand faced by exporters of quality-differentiated goods in shaping the transport mode choice. We find that more considerable demand volatility induces more exporters to opt for air shipping, and more so if they produce high-quality goods. We also produce supporting evidence based on U.S. data at the exporter-district-product level
Gamps_00979.jpg
No full text3D model of GAMPS-00979, fragmentary cheloniid costal plate from the upper Miocene (Tortonian) strata of the Arenaria di Ponsano Formation (Tuscany, central Italy) featuring a Karethraichnus cf. lakkos boring on its external surface. This fossil is currently housed in the palaeontological collection of Gruppo Avis Mineralogia e Paleontologia Scandicci (=GAMPS, Badia a Settimo, Scandicci, FI, Italy). GAMPS-00979 is described in the following article:Collareta, A., Merella, M., Bosselaers, M., Casati, S., Di Cencio, A., Bianucci, G. (2022). A Karethraichnus boring on a turtle shell bone from the Miocene of Italy is assessed as the attachment scar of a platylepadid symbiont.

Quality Ladders in a Ricardian Model of Trade with Nonhomothetic Preferences
Full text linkThe North–South trade literature has traditionally explored conditions under which international trade might further magnify income disparities between the advanced North and the backward South. We show that even when no single country is initially more advanced than any other one and productivity changes are uniform and identical in all countries, trade may still be a source of income divergence when nonhomothetic preferences and quality ladders are jointly taken into account. Income divergence will be experienced when comparative advantages induce patterns of specialization that, although initially optimal for all countries, do not offer the same scope for quality upgrading of final products
Love for quality, comparative advantage, and trade
Full text linkWe propose a Ricardian trade model with horizontal and vertical differentiation, where willingness to pay for quality rises with income, and productivity differentials across countries are stronger for high-quality varieties of goods. Our theory predicts that the scope for trade widens and international specialisation intensifies as incomes grow and wealthier consumers raise the quality of their consumption baskets. This implies that comparative advantages strengthen gradually over the path of development as a by-product of the process of quality upgrading. The evolution of comparative advantages leads to specific trade patterns that change over the growth path, by linking richer importers to more specialised exporters. We provide empirical support for this prediction, showing that the share of imports originating from exporters exhibiting a comparative advantage in a specific product correlates positively with the importer's GDP per head
