In this chapter we give a brief overview of corporate governance in the United States (‘US’), the United Kingdom (‘UK’), New Zealand, Canada, South Africa, India and Singapore, some of the major Anglo-American corporate governance jurisdictions that are based on the unitary (one-tier) board model. In Chapter 12 we deal with corporate governance developments in the European Union (‘EU’), the G20/OECD Principles of Corporate Governance, and corporate governance in Germany, Japan and China. The Principles include traditional Anglo-American corporate governance principles but go wider – as well as principles applying to a traditional unitary board structure, they include principles applying to a typical two-tier board structure.

If the mass of a hadron is large enough, decays into final states that can be reached by strong interaction, that is, without violating any selection rule, are possible. The lifetime is then extremely short, of the order of a yoctosecond (10−24 s). These hadrons decay practically where they were born. We show how they are observed as ‘resonances’.

Hadrons, both baryons and mesons, were discovered in rapidly increasing numbers in the 1950s and early 1960s. How their quantum numbers, spin, parity and isospin were measured. Gradually it became clear that hadrons with the same spin and parity could be grouped in multiplets of the SU(3) symmetry. Proposal of the quark model and experimental verifications of its predictions. With increasing accelerator energies, more surprises were to come. The quarks are not only the three originally known, u, d and s, but three more exist, c, b and t. And more leptons were found, in total three ‘families’ of fundamental fermions, each with two quarks, a charged lepton and its neutrino.

In modern physics, symmetries are a powerful tool to constrain the form of equations, namely the Lagrangian that describes the system. Equations are assumed to be invariant under the transformation of a given group, which may be discrete or a continuous Lie group. Classification of the various types of symmetry. The concept of spontaneous symmetry breaking. It will evolve into the Higgs mechanism, which gives origin to the masses of the vector bosons that mediate the weak interactions, of the quarks and of the charged leptons.

The discrete symmetries, in particular the parity and the particle–antiparticle conjugation operations and the corresponding quantum numbers.

An important dynamical symmetry of the hadrons, the invariance of the Lagrangian under rigid rotations in an ‘internal’ space, the isospin space. The unitary group is SU(2).

In Chapter 3, we are fortunate to have three contributing authors, Susan Poetsch, Denise Angelo and Rhonda Anjilkurri Radley, bringing their research and lived experience in Aboriginal and Torres Strait Islander languages.. The chapter describes a dynamic and detailed picture of the multilingualism of communities and the developing ecologies of Aboriginal and Torres Strait Islander languages. Through six real-life vignettes and visits to communities, we meet multilingual Indigenous children in their daily lives, who move between multiple modes of language use, with their families and in school. The chapter highlights the widespread use of new Indigenous languages (including creoles such as Kriol and Yumplatok) and the revival and revitalisation of traditional Aboriginal and Torres Strait Islander languages in some communities. The chapter also highlights Aboriginal and Torres Strait Islander people’s ways of using English, and the linguistic challenges faced by many children in school.

Chapter 1 encourages readers to reflect on their own experience of linguistic diversity, and their perception of the multilingual nature of rural, remote and urban Australia today. The chapter establishes its relevance to readers’ development in the first AITSL Teaching Standards (‘Know your students and how they learn’).

Chapter 2 engages you with both international and local research evidence of the clear connections between teacher support of multilingualism in students, and student wellbeing and school achievement. Understanding the implications of these research findings is core to the argument of the book, and to your engagement with and commitment to developing pedagogy for linguistically diverse classrooms.

In this chapter the focus is on corporate governance developments in countries where the two-tier board system is used. The number of EU member states with different corporate law systems makes corporate governance harmonisation quite difficult, but also leads to very interesting and dynamic discussion within the EU. The G20/OECD Principles of Corporate Governance cover board structures. Germany has a two-tier board structure with employee representatives forming part of the supervisory board. Elements of the German corporate governance model influenced the original Japanese corporate governance model, but Anglo-American influence emerged after World War II. China has a unique corporate governance model because Chinese corporations were traditionally state-owned and many major corporations are still either state-owned or state-controlled. Nevertheless, elements of both the German model and the Anglo-American model, especially as far as independent, non-executive directors for listed companies are concerned, have influenced the Chinese corporate governance model.

The electroweak unification appears mainly in the neutral current processes. The transition probabilities of all of them are predicted in terms of the weak mixing angle. Measuring the weak mixing angle.

Theory predicts the existence of three vector bosons, W+, W− and Z0. It does not predict their masses, but precisely states how they are related with two measured quantities: the Fermi constant and the weak mixing angle. The UA1 experiment and the discovery of the vector bosons.

The precision tests of the electroweak theory performed at the LEP electron–positron collider and at the Tevatron proton–antiproton collider.

The last missing element of the SM, the Higgs boson. The spontaneous symmetry breaking and the boson. The searches at LEP and at the Tevatron. The Large Hadron Collider and the ATLAS and CMS experiments. The discovery of 2012. Checking Higgs physics, measuring its mass and width, its spin and parity, its couplings to the bosons and to the fermions. All agree with the predictions of the Standard Model, so completing the experimental verification of its basic building blocks.
