Dairying in the Waikato Region of New Zealand: An overview of historical statistics

The dairy industry is an important contributor to the economy of the Waikato region of New Zealand. An understanding of the history and development of the dairy sector in the different districts of the Waikato region is important in terms of informing future policy. Unfortunately there are currently no consistent long-run spatially disaggregated data sets available for the districts of the Waikato region that extend any further back than 1990. In this paper, we present the current state of dairy farming data available for the territorial local authorities within the Waikato region, and briefly discuss a set of methods that will be employed to develop consistent long-run spatially disaggregated data series for (i) milk production; (ii) total number of productive dairy cattle; (iii) total number of dairy farms; and (iv) total effective hectares devoted to dairy production

Dairy productivity in the Waikato region, 1994-2007

The dairy industry is a major contributor to both the New Zealand economy as a whole and to the Waikato regional economy in particular. The industry is experiencing a period of considerable change, with increases in dairy conversion, increased intensification, and increasing use of nitrogen fertilisers, each of which has an associated environmental cost. In this paper the productivity performance of the mature dairy industry in the Waikato region is investigated, using panel data at the sub-regional level from 1994 to 2007. Overall we show that, under a range of specifications, productivity growth independent of increasing land use and herd numbers has been significantly below the four percent industry target. This suggests that, if the four percent goal were to be met in the absence of significant technological progress, further increases in fertiliser use, land use, and/or farming intensity would be required.Productivity, dairy industry, Waikato., Agricultural and Food Policy, Environmental Economics and Policy, Farm Management, Land Economics/Use, Productivity Analysis,

Entrepreneurship and Debt: Growth Aversion, Debt Aversion, Overconfidence, and the Effects on Small Business Credit Decisions

Widespread empirical consistency with the pecking order theory of capital structure (Myers & Majluf, 1984) has led researchers to conclude that small and medium sized enterprises conform to this theory’s predictions. In chapter 2, a formal model is presented that allows for plausible and empirically supported psychological owner/manager objectives in addition to the profit motive. This chapter provides an alternative explanation of preferences for low leverage that does not rely on informational asymmetry, as well as predicting limits on firm sizes, and the existence of collateral. In chapter 3, a formal model of the entrepreneurship decision with credit is presented for firms with managers who overestimate their probability of success. Explanations for credit rationing, predatory lending, and the existence of collateral are produced and the welfare implications of overconfidence are investigated in an equilibrium model. It is found that overconfidence can increase overall welfare but harms entrepreneurs who are able to engage in poor projects

The effects of large- scale anti- contagion policies on the COVID-19 pandemic

Governments around the world are responding to the novel coronavirus (COVID-19) pandemic1 with unprecedented policies designed to slow the growth rate of infections. Many actions, such as closing schools and restricting populations to their homes, impose large and visible costs on society, but their benefits cannot be directly observed and are currently understood only through process-based simulations2–4. Here, we compile new data on 1,717 local, regional, and national non-pharmaceutical interventions deployed in the ongoing pandemic across localities in China, South Korea, Italy, Iran, France, and the United States (US). We then apply reduced-form econometric methods, commonly used to measure the effect of policies on economic growth5,6, to empirically evaluate the effect that these anti-contagion policies have had on the growth rate of infections. In the absence of policy actions, we estimate that early infections of COVID-19 exhibit exponential growth rates of roughly 38% per day. We find that anti-contagion policies have significantly and substantially slowed this growth. Some policies have different impacts on different populations, but we obtain consistent evidence that the policy packages now deployed are achieving large, beneficial, and measurable health outcomes. We estimate that across these six countries, interventions prevented or delayed on the order of 62 million confirmed cases, corresponding to averting roughly 530 million total infections. These findings may help inform whether or when these policies should be deployed, intensified, or lifted, and they can support decision-making in the other 180+ countries where COVID-19 has been reported7.https://doi.org/10.1038/s41586-020-2404-

Violation of Bell inequality for thermal states of interaction qubits via a multi-qubit Heisenberg model

We study the violations of Bell inequality for thermal states of qubits in a multi-qubit Heisenberg model as a function of temperature and external magnetic fields. Unlike the behaviors of the entanglement the violation can not be obtained by increasing the temperature or the magnetic field. The threshold temperatures of the violation are found be less than that of the entanglement. We also consider a realistic cavity-QED model which is a special case of the mutli-qubit Heisenberg model.Comment: 5 pages, 5 figures, few changed, accepted by New J. Phy

Fungal diversity of selected habitat specific Cynorkis species (Orchidaceae) in the central highlands of Madagascar

About 90% of Cynorkis species are endemic to the biodiversity hotspot of Madagascar. This terrestrial habitat-specific genus received little study for fungal diversity to support conservation. We evaluated the diversity of culturable fungi of 11 species and soil characteristics from six sites spanning a >40 km radius in and along the region’s inselbergs. Peloton-forming fungi were grown in vitro from root/protocorm slices and positively identified using DNA sequencing. The fungal diversity was then correlated with soil pH, NO3-N, P, and K. All species harbored either putative mycorrhizal associates in the Rhizoctonia complex or Hypocreales fungi. Tulasnella Operational Taxonomic Units (OTUs) were most prevalent in all soil types while Serendipita OTUs were found in species inhabiting granite/rock outcrops in moist soil (seepage areas). Most Cynorkis species were present in soil with low NO3-N and P levels with diversity of mycorrhizal fungi inversely correlated to NO3-N levels. Of the different orchid life stages sampled, only one species (Cynorkis fastigiata) yielded putative mycorrhizal fungi from juvenile stages. As diversity of mycorrhizal fungi of Cynorkis spp. was negatively correlated with NO3-N, and majority of the studied taxa were found in soils with low NO3-N and P contents, reintroduction studies must include analysis of N and P in detail. For the first time, we showed that the assemblage of culturable fungi in the roots of habitat-specific species of Cynorkis (Orchidaceae) are intimately tied to specific soil characteristics

Dancing in the office: A study of gestures as resistance

Following the art-body-ethics turn in management studies we use dance as an analogy in order to explore how the body can resist organisational control in office work contexts. We argue that in office work gestures can be a site of post-recognition resistance. Drawing on two art videos and on dance studies, we explain that this is operated either through arrest or through flow. In fact aesthetic experiments in gesturing disrupt the work rhythm needed for organisational efficiency and enforced by organisational control. This allows us to contribute primarily to the literature on resistance in organisation studies and relatedly to the growing literature on dance in organisation studies through demonstrating how dance can be a source of resistance

The big picture? Video and the representation of interaction

Researchers who use video to record interactions usually need to translate the video data into another medium at some stage in order to facilitate its analysis and dissemination. This article considers some methodological issues that arise in this process by examining transcripts, diagrams and pictures as examples of different techniques for representing interaction. These examples are used to identify some general principles for the representation of data where video is the source material. The article presents an outline of guided interaction and this is used as a case for illustrating these principles in the context of young children, technology and adults in pre-school settings. Although the article focuses on a specific study and solution, the principles are applicable in all cases where video is used as a source of data for the representation of interaction, whether or not it is technologically mediated
