System of farm cost accounting

The business farmer wishes to know how much he is making or losing on his business each year, how much he is making or losing on each crop or class of animals, and how he can improve his business so as to make more money. The function of farm cost accounting is to supply this information. Cost accounting for the farm is the same sort of work large manufacturing companies do to learn whether they are making a profit on their different products. The farmer wants to know whether his wheat pays, whether his cows pay, or his orchard. These are some of the questions a set of farm cost accounts will settle

The Conservative Party crisis, 1929-1931

The thesis covers the politics of the Conservative Party from the general election defeat of May 1929 to the formation of the National Government in August 1931. It relates the internal crisis in the Party to the pressures of the Party rank and file, and to the general political and economic situation, in order to analyse the process by which Party policy evolved. Debate centred upon two questions: protection and India. In the case of the former, the role of its advocates in the press is discussed. Overall, the thesis emphasised the power of the position of the Party Leader, Baldwin. The Party crisis passed through six distinct phases. In the first (May-August 1929) the status quo in policy was preserved; but during the second (September 1929-March 1930), the balance tilted in the direction of advance over protection, but was restrained by the reluctance of the northern regions. A truce with the press followed (March-June 1930) but collapsed in mid-summer, leaving the leaders dangerously out of touch with their followers' views during the fourth phase of acute crisis (July-October 1930). At the end of the latter period the leaders accommodated their position, appeasing all but a small minority of dissidents, and isolating the press campaign. However, the fifth phase (October 1930-March 1931) saw a renewed outbreak of unease, due to the question of India and the leadership failures of Baldwin himself. In the final phase (March-August 1931) Baldwin re-established his position, and the Conservatives seemed set for electoral victory, having united around the policy of reducing government expenditure. The Party did not seek Coalition, but was diverted into joining the National Government by the sudden and serious financial crisis, believing it to be a temporary emergency expedient

Adolescent television viewing and unhealthy snack food consumption: the mediating role of home availability of unhealthy snack foods

Objective To examine whether home availability of energy-dense snack foods mediates the association between television (TV) viewing and energy-dense snack consumption among adolescents.Design Cross-sectional.Setting Secondary schools in Victoria, Australia.Subjects Adolescents (n 2984) from Years 7 and 9 of secondary school completed a web-based survey, between September 2004 and July 2005, assessing their energy-dense snack food consumption, school-day and weekend-day TV viewing and home availability of energy-dense snack foods.Results School-day and weekend-day TV viewing were positively associated with energy-dense snack consumption among adolescent boys (β = 0·003, P < 0·001) and girls (β = 0·03, P < 0·001). Furthermore, TV viewing (school day and weekend day) were positively associated with home availability of energy-dense snack foods among adolescent boys and girls and home availability of energy-dense snack foods was positively associated with energy-dense snack food consumption among boys (β = 0·26, P < 0·001) and girls (β = 0·28, P < 0·001). Home availability partly mediated the association between TV viewing and energy-dense snack consumption.Conclusions The results of the present study suggest that TV viewing has a significant role to play in adolescent unhealthy eating behaviours. Future research should assess the efficacy of methods to reduce adolescent energy-dense snack food consumption by targeting parents to reduce home availability of energy-dense foods and by reducing TV viewing behaviours of adolescents

Nonlinear time-harmonic Maxwell equations in an anisotropic bounded medium

We find solutions $E:\Omega\to\mathbb{R}^3$ of the problem \begin{eqnarray*} \left\{ \begin{aligned} &\nabla\times(\mu(x)^{-1}\nabla\times E) - \omega^2\epsilon(x) E = \partial_E F(x,E) &&\quad \text{in }\Omega\\%\newline &\nu\times E = 0 &&\quad \text{on }\partial\Omega \end{aligned} \right. \end{eqnarray*} on a bounded Lipschitz domain $\Omega\subset\mathbb{R}^3$ with exterior normal $\nu:\partial\Omega\to\mathbb{R}^3$. Here $\nabla\times$ denotes the curl operator in $\mathbb{R}^3$. The equation describes the propagation of the time-harmonic electric field $\Re\{E(x)e^{i\omega t}\}$ in an anisotropic material with a magnetic permeability tensor $\mu(x)\in\mathbb{R}^{3\times3}$ and a permittivity tensor $\epsilon(x)\in\mathbb{R}^{3\times3}$. The boundary conditions are those for $\Omega$ surrounded by a perfect conductor. It is required that $\mu(x)$ and $\epsilon(x)$ are symmetric and positive definite uniformly for $x\in\Omega$, and that $\mu,\epsilon\in L^{\infty}(\Omega,\mathbb{R}^{3\times 3})$. The nonlinearity $F:\Omega\times\mathbb{R}^3\to\mathbb{R}$ is superquadratic and subcritical in $E$, the model nonlinearity being of Kerr-type: $F(x,E)=|\Gamma(x)E|^p$ for some $2<p<6$ with $\Gamma(x)\in GL(3)$ invertible for every $x\in\Omega$ and $\Gamma,\Gamma^{-1}\in L^\infty(\Omega, \mathbb{R}^{3\times 3})$. We prove the existence of a ground state solution and of bound states if $F$ is even in $E$. Moreover if the material is uniaxial we find two types of solutions with cylindrical symmetries.Comment: to appear in J. Funct. Ana
