Philosophical thought of the School of the Sextii

2014

Around the first half century B.C. the first Roman school of philosophy arose, which was called School of Sextii. The known members of the School were: Quintus Sextius the Elder, founding father of the School, Sextius Niger, Quintus' son, who became scholarch of the School after his father's death, Sotion, Papirius Fabianus (both teachers of Seneca the Younger), Crassicius Pasicles, a grammarian, and Celsius Cornelius, an expert doctor. The School followed the footsteps of the Hellenistic schools, and similar to these, the pursuit of happiness was its purpose. The school of the Sextii had taken to heart that part of the philosophy called physical, characterizing itself mainly as a philosoph…

The Effect of Temporal Changes and Environmental Trophic Condition on the Isotopic Composition (omega13C and omega15N) of Atherina boyeri (Risso, 181…

2002

δ13C and δ15N of organic matter sources and consumers were employed to analyse trophic differentiation between a benthic consumer, Gobius niger (L., 1758) (Pisces, Osteichthyes), and a pelagic consumer, Atherina boyeri (Risso, 1810) (Pisces, Osteichthyes) in a Mediterranean coastal lagoon (Lake of Sabaudia) in winter and summer 1999. Trophic differences between the two species throughout the two sampling periods were related to the environmental trophic condition (i. e. nutrient and phytopigment concentrations). Although these two fish have different habitats, they both exploited benthic organisms, above all in summer. When the nutrient and phytopigment concentrations were higher (summer), …

Smartphone Usage Among Millennial in Finland and Implications for Marketing Segmentation Strategies: Lessons for Nigeria

2018

The study examines smart phone usage by millennials based on different criteria of operating system, Wi-Fi, text messaging, internet surfing and social media. The study used quantitative methodology and data were gathered with online questionnaires with 391 young smartphone users in Finland. The Millennial were clustered into five levels. The results reveal the prominent status of profiling in a developed market and how marketers in emerging markets can apply segmentation and targeting strategies using instant messaging, text messages, email, mobile app, gamification and social media based on the profile of each segment. Nigerian policy makers should adopt a framework to make smartphone aff…

Do tax policies discriminate against female traders? A gender framework to study informal marketplaces in Nigeria

2022

Scholars have long debated formalizing the informal sector through taxation, but how do these processes affect gender inequalities? Our study in Nigerian markets contributes a gender framework to the equitable taxation literature on formalization. The study draws on a survey of 451 traders in 12 markets, key informant interviews, and ethnographic research in four markets of two states. We find that in at least two situations taxation policies discriminated against women implicitly: (1) male tax collectors had higher incidences of harassment on all traders and (2) taxing traders with flat taxes penalized women, as they earned less than men but were taxed the same.长期以来，学者们一直在辩论通过税收将非正式部门正规化，但…

Flow cytometric kinetic assay of the activity of Na+/H+ antiporter in mammalian cells.

2004

Background The Na+/H+ exchanger (NHE) of mammalian cells is an integral membrane protein that extrudes H+ ion in exchange for extracellular Na+ and plays a crucial role in the regulation of intracellular pH (pHi). Thus, when pHi is lowered, NHE extrudes protons at a rate depending of pHi that can be expressed as pH units/s. Methods To abolish the activity of other cellular pH-restoring systems, cells were incubated in bicarbonate-free Dulbecco's modified Eagle's medium buffered with HEPES. Flow cytometry was used to determine pHi with 2′,7′-bis-(2-carboxyethyl)-5-(and-6)-carboxyfluorescein acetoxymethyl ester or 5-(and-6)-carboxy SNARF-1 acetoxymethyl ester acetate, and the appropriate fluo…
