Year: 2007
Subjects: subject: Productivity Analysis
subject: productivity
subject: competitive advantage
subject: farm performance

description: The objective of this paper was to examine productivity differences among individual farms. The Malmquist index approach was used to estimate productivity for each farm and to decompose productivity change into technical change and efficiency change. The relationship between productivity and farm size was explored. In addition, the relationships between each productivity component and outputs, and each productivity component and inputs were explored. For the sample of Kansas farms used in this study, average annual productivity change over the 20-year period for the sample of farms was 2.16%. Technical change averaged 1.54% per year and efficiency change averaged 0.61% per year. Productivity was significant and positively related to farm size and feed grain production, and significant and negatively related to labor use. The largest farms, those with real gross farm income greater than $500,000, had the largest annual average productivity change at 3.20%.

Heidegger's people : from the state to the poetry
Creators: name: Phillips, JA
Publisher: name: University Of Tasmania
Year: 2023

description: This dissertation is an attempt to expound Heidegger' s conception of Volk. Its thesis is that there is but the one conception of Volk behind both Heidegger' s engagement and disengagement with National Socialism. In ¬¨vü74 of Being and Time, Heidegger introduces the word \Volk\" in a discussion of the essential historicality of Dasein - the Volk which is not to be understood as an aggregate of subjects takes its definition (as much as Dasein itself) from the being-outside-of-itself of ecstatic temporality. Given this definition of the Volk Heidegger must arguably have welcomed in the \"folkish\" self-assertion of 1933 the assertion of Being's irreducibility to the static temporality of the present-at-hand. After his withdrawal from university politics in 1934 Heidegger criticised the regime but he did not criticise his own error. The philosophical grounds for this stance towards error can be discerned in his defence of being-outside-of-itself in his confrontation with Hegel (chapter I). With its discussion of the failure of knowledge the rectoral address is an exhortation of the Volk to the error of its own essence as Dasein (chapter II). Heidegger' s subsequent lectures on art develop the anti-modernist conception of the German people in the context of a reappraisal of the ecstatic character of mimesis (chapter III). Heidegger' s notion of a non-positive and hence non-imperialistic Heimat informs his readings of Kant and Holderlin (chapter IV). And in the 1952 essay on Trakl \"Geschlecht\" carries the being-outside-of-itself of \"Volk\" to a contamination with the animal (chapter V)."

description: Contemporary Research and Development (R&D) projects are increasingly concerned with setting outcome targets such as measurable improvements in enterprise profit, industry growth, environmental health or resource use efficiency. This paper describes the application and ongoing development of a â€˜Sustainable Improvement and Innovationâ€™ (SI&I) model for designing and managing medium to longer term R&D projects to achieve and sustain outcomes, improvements and innovations in agricultural enterprises, industries and regions. The model is applied in two Beef Profit Partnerships (BPP) projects, one by emerging farmers in two provinces in South Africa, and the other by commercial beef producers in Australia. The South African project was funded by the Australian Centre for International Agricultural Research over five years; the Australian project is funded by the Cooperative Research Centre for Beef Genetic Technologies and is in the second of seven years. The primary objective of both projects is to accelerate the rate of adoption of new technologies and to measure and monitor the productivity and profitability outcomes in farming systems and in the broader region. Another objective is to undertake adoption science research on this process and to measure and monitor partnership and capacity building outcomes. Through the use of the model in the South African BPP project, measurable improvements in profit per beef enterprise, each year, in the participating communities and regions have been achieved, and these improvements have been sustained across an increasing number of cattle enterprises and communities. Further, the SI&I process implemented as an integral part of the BPP project has been demonstrated to lead to measurable, positive economic outcomes, even over a relatively short period. The SI&I model is presented in detail, the results from the South African application are reported, and the value of the model and its methods for extending the approach to Australia and elsewhere are discussed. Conclusions are made about the application of the SI&I model in R&D projects focused on high rates and scales of impact.

Gravitation and inertia; a rearrangement of vacuum in gravity
Creators: name: Ter-Kazarian, Gagik
Publisher: name: arXiv
Year: 2010
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We address the gravitation and inertia in the framework of 'general gauge principle', which accounts for 'gravitation gauge group' generated by hidden local internal symmetry implemented on the flat space. We connect this group to nonlinear realization of the Lie group of 'distortion' of local internal properties of six-dimensional flat space, which is assumed as a toy model underlying four-dimensional Minkowski space. The agreement between proposed gravitational theory and available observational verifications is satisfactory. We construct relativistic field theory of inertia and derive the relativistic law of inertia. This theory furnishes justification for introduction of the Principle of Equivalence. We address the rearrangement of vacuum state in gravity resulting from these ideas.

description: GM and non-GM coexistence, as defined by the European commission, defines a product as non-GM if it contains less than 0.9% of GM material. To avoid the risk of mixing GM and non-GM, we made a model of supply chain management rules and strategies for crop collection planning for a small farming region. It simulates (i) the GM and non-GM proportions at the end of the supply chain and (ii) the transportation and processing costs. Three strategies were evaluated. One has no specific planning. Batches were taken as crops arrived at the silo. A second is on a spatial basis and allocates each silo to a single crop batch. A third is time based and allocates part of the collection time to one product. We show that the spatial strategy allows all the non GM production to be segregated, but at a high cost. On the contrary the time strategy leads to a lower cost but with lower segregation results.

description: La Manera case study is one of several developed for an international education programme named Improving Agriculture Studentsâ€™ Understanding of Global Production Systems through Distance Learning involving cooperation between academics at four universities on different continents: Kansas State University, Moscow University, Queensland University and ORT University-Uruguay. A set of multimedia resources (written case studies and related audiovisuals) was developed aimed at helping agricultural students better understand the managerial environment faced by producers in different parts of the world. The concept, funded through a United States Department of Agriculture (USDA) Challenge Grant, was to develop two farm cases in each of four continents (North America, South America, Europe and Australia), giving eight cases in all that could be used as the basis for a semester-long graduate or undergraduate course in applied farm management. This paper presents one of the developed cases: â€˜La Manera 2000 and 2005â€™ which outlines the farm management challenges and responses by a farmer in Uruguay. Part one of this paper describes the teaching objectives of the educational materials developed under the international education programme. Part two presents a summary of La Maneraâ€™s case studies. Part three presents a brief teaching note. Part four describes how the case study has been used teaching undergraduate classes in University of Queensland, Australia, and some of the results obtained.

description: A digital hadronic calorimeter using MICROMEGAS as active elements is a very promising choice for particle physics experiments at future lepton colliders. These experiments will be optimized for application of the particle flow algorithm and therefore require calorimeters with very fine lateral segmentation. A 1 m2 prototype based on MICROMEGAS chambers with 1x1 cm2 readout pads is currently being developed at LAPP. The GEANT4 simulation of the physics performance of a MICROMEGAS calorimeter is presented. The main characteristics, such as energy resolution, linearity and shower profile, have been carefully examined for various passive materials with pions over a wide energy range from 3 to 200 GeV. The emphasis is put on the comparison of the analog and digital readout.

Squamish socialization
Creators: name: Ryan, Joan
Publisher: name: University of British Columbia
Year: 2011

description: This is a study of the socialization processes among major extended families on the Capilano Reserve. Ethnographic data introduce the social environment and provide the context for an analysis of socializing experiences. The analysis of socialization also gives insights into social change and adaptive responses, and focuses on the acquisition of ethnic identity within a multicultural setting. The thesis seeks to show how children, youths and adults resolve personal dilemmas of formulating an identity when the sanctions of socialization processes are in opposition. The study points out that any individual may be involved in first, second and third processes of socialization which may be experienced simultaneously or in sequence. The context in which they occur is a complex one bounded by membership in a specific extended family. The individual must also accommodate the demands of opposing family groups who form the Band corporate structure and the demands of the adjacent white society in which he must also be involved. Primary emphasis is placed on the description and analysis of the process of socialization rather than on the practices. This provides an extension to the traditional literature on socialization and a fuller understanding of the dynamics of interaction between adults and children as well as among those adults who undergo the third process of socialization. Findings indicate that cultural conflicts, if they exist, do not necessarily result in perceptual conflicts. Rather, one individual may choose a primary path which avoids conflicting choices; another may tolerate exposure to conflicting processes and emerge as a bicultural person. In either case, the individual is Squamish by self-definition. The ineffective socialization that is carried out by parents who were themselves unable to complete a socialization process in either white or Squamish culture is also discussed. This discussion links historical determinants of life styles with the re-establishment of a closed system for socialization within the extended family. Such a closure restores to the grandparental generation their roles as primary socializers and cultural custodians. It also allows some youths to choose to become bicultural. The concluding statement of the thesis links the presentation of Squamish theories of socialization and the observed practices with specific theoretical concerns about development, identity, and cognitive balance which have a general application.
A dietary study of Moroteuthis ingens and other Southern Ocean squid species : combined stomach contents and fatty acid analyses
Creators: name: Phillips, Katrina L.
Publisher: name: University Of Tasmania
Year: 2023

description: The squid fauna are a key component of the Southern Ocean ecosystem, although unfortunately little is known of their distribution, biology and ecology. While the biomass of squid in the Southern Ocean must impose a large amount of predatory pressure on lower trophic levels, few dietary data exist for any of the Southern Ocean species. Conventional dietary analyses of squid are fraught with many sources of bias, and therefore this study has employed complementary stomach contents and fatty acid analyses to investigate aspects of the diet of Southern Ocean squid. The diet of the onychoteuthid Moroteuthis ingens was largely comprised of myctophid fish, and the digestive gland of M. ingens was rich in lipid and found to be an ideal source of fatty acid dietary tracers that are unmodified from the diet. Fatty acid dietary tracers were then applied in combination with stomach contents analyses to investigate the temporal, spatial and sizerelated dietary patterns of M. ingens. Using these complementary techniques, the diet of M.ingens was found to vary significantly on an interannual and seasonal basis within the vicinity of Macquarie Island, largely due to fluctuations in the proportions of myctophid fish species in the diet. Moroteuthis ingens also exhibited spatial variations in diet among Macquarie Island, the Falkland Islands, the Chatham Rise and Campbell Plateau (the latter two sites located within New Zealand waters). The diet at the New Zealand sites was characterised by a proportion of temperate myctophid species not identified at other sites, whereas squid collected from the Falkland Islands consumed a much greater proportion of cephalopod prey. Lipid class and fatty acid analyses also indicated that the diet varied considerably between the Chatham Rise and Campbell Plateau, most likely due to the influences of different oceanographic regimes. Stomach contents and fatty acid analyses of squid collected from the Falkland Islands indicated that M. ingens switches from a crustacean- and cephalopod-based diet to a fish- and cephalopod-diet at around 200 mm mantle length. Lipid class and fatty acid analyses of the other Southern Ocean squid indicated that oegopsid species accumulate a large amount of lipid in the digestive gland. This lipid has been determined to be of dietary origin, and will thus provide a rich source of fatty acid dietary tracers applicable to future food-web studies of squid. Further consideration of the mode of lipid and fatty acid storage in the digestive gland will be required before squid fatty acid profiles can be reliably applied to dietary studies of higher trophic predators.

description: Implementation of best management practices into the beef cow enterprise is critical for long-term success. Previous literature suggests that pregnancy testing is valuable to the beef cow operation; however, less than half of producers in the southern Plains region of the United States utilize pregnancy testing. The objective of this research is to determine the expected value of pregnancy testing and the subsequent adoption of an effective culling practice on first-time non-pregnant beef cows relative to a system that does not use pregnancy testing or a culling strategy. Results show that the value of adopting pregnancy testing and an effective culling practice for first-time non-pregnant cows ranged between $54 and $76 head-1, depending upon the year. With the cost of pregnancy testing ranging between $2 and $5 head-1, the value of the risk-reducing information gleaned from pregnancy testing tends to warrant adoption.

Magnetostratigraphy of glacial lake sediments and dating of Pleistocene glacial deposits in Tasmania
Creators: name: Pollington, MJ
Publisher: name: University Of Tasmania
Year: 2023

description: Magnetostratigraphic techniques have been applied to Quaternary glacial deposits of western, central western and central northern Tasmania. The aims of this study were to examine the validity of the application of these techniques to glacial lake sediments, to separate glacigenic deposits that were beyond the range of radiocarbon dating and to compare the stratigraphy determined by these methods with the established stratigraphy, on the basis of their magnetic polarity. The extant model of the glacial stratigraphy of Tasmania is based on morphostratigraphic, lithostratigraphic and biostratigraphic mapping, and the analysis of weathering characteristics, particularly weathering rind analysis. The model recognises at least three glaciations, the Margaret or Last Glaciation, the Henty Glaciation and the Linda Glaciation. The magnetostratigraphic framework developed as a result of this study has largely confirmed the established stratigraphic framework, with the exception of some deposits of Henty Glaciation age. The Henty Glaciation has been considered to be the Penultimate Glaciation in Tasmania, and hence of Middle Pleistocene age. Evidence from the Henty Surface has demonstrated that some of the deposits in the Henty Glaciation type area must be > 730 ka in age and hence of Early Pleistocene age. The Linda Glaciation has been considered to be of very considerable age by many earlier workers. This study has demonstrated that the Linda Glaciation and its equivalents are >730 ka in age, and hence of Early Pleistocene or even Late Tertiary age. The Linda Glaciation appears to have been a complex event, consisting of either a number of glacial advances, or two or more separate glaciations. Magnetostratigraphic techniques have been shown to be useful and valid techniques for the determination and clarification of the ages of Middle and Early Pleistocene deposits in stratigraphic sequences. Glacial lake sediments have been shown to be suitable material for the application of such techniques. The suitability of material for palaeomagnetic analysis varies considerably, so some results are considered to be more reliable than others. Accordingly, a reliability index based on a number of factors has been constructed. Glacial lake sediments derived from sources containing dolerite or volcanic detritals are particularly suitable as they have strong magnetic signatures. Correlation of the glacial events of Tasmania with those of New Zealand and South America is not possible at present. Magnetostratigraphy will provide a means of correlating these events when similar frameworks have been established for these areas.

description: We announce the discovery of a quasar behind the disk of M31, which was previously classified as a remarkable nova in our neighbour galaxy. The paper is primarily aimed at the outburst of J004457+4123 (Sharov 21), with the first part focussed on the optical spectroscopy and the improvement in the photometric database. Both the optical spectrum and the broad band spectral energy distribution of Sharov 21 are shown to be very similar to that of normal, radio-quiet type 1 quasars. We present photometric data covering more than a century and resulting in a long-term light curve that is densely sampled over the past five decades. The variability of the quasar is characterized by a ground state with typical fluctuation amplitudes of ~0.2 mag around B~20.5, superimposed by a singular flare of ~2 yr duration (observer frame) with the maximum at 1992.81 where the UV flux has increased by a factor of ~20. The total energy in the flare is at least three orders of magnitudes higher than the radiated energy of the most luminous supernovae, provided that it comes from an intrinsic process and the energy is radiated isotropically. The profile of the flare light curve appears to be in agreement with the standard predictions for a stellar tidal disruption event where a ~10 M_sun giant star was shredded in the tidal field of a ~2...5 10^8 M_sun black hole. The short fallback time derived from the light curve requires an ultra-close encounter where the pericentre of the stellar orbit is deep within the tidal disruption radius. Gravitational microlensing provides an alternative explanation, though the probability of such a high amplification event is very low.

Subjects: subject: Research Methods/ Statistical Methods

description: Individual farm accountancy data sources such as the European Farm Accountancy Data Network (FADN) include no specific information on the spatial location of farms. However, spatial characteristics and site conditions determine the farmsâ€™ production potential and its influence on the surrounding environment. Spatially explicit models that make use of the FADN data need to be able to recreate a landscape including the location of the farms in a plausible way. This paper investigates the minimum sample size of farm locations required to insure the ability to reproduce a reliable map of a given region. This is done by analysing relative locations between all the 1871 farms present in the Danish river GudenÃ¥ watershed. As we have detailed information about each of the farms we can categorize the farms in groups in a way similar to what one would be able to do with farms from a FADN sample. By utilising the rich information that the FADN sample contains to create a multidimensional spatial set of requirements that the farms on average have to meet it is possible to reduce the number of available locations to a minimum. This investigation is divided into the following two-step procedure: First the variability of an individual farms spatial relationship is investigated with regard to variation in sample size and composition. Secondly is the average values investigated with regard to variation in sample size and composition.

description: It has long been known that for the comparison of pairwise nested models, a decision based on the Bayes factor produces a consistent model selector (in the frequentist sense). Here we go beyond the usual consistency for nested pairwise models, and show that for a wide class of prior distributions, including intrinsic priors, the corresponding Bayesian procedure for variable selection in normal regression is consistent in the entire class of normal linear models. We find that the asymptotics of the Bayes factors for intrinsic priors are equivalent to those of the Schwarz (BIC) criterion. Also, recall that the Jeffreys--Lindley paradox refers to the well-known fact that a point null hypothesis on the normal mean parameter is always accepted when the variance of the conjugate prior goes to infinity. This implies that some limiting forms of proper prior distributions are not necessarily suitable for testing problems. Intrinsic priors are limits of proper prior distributions, and for finite sample sizes they have been proved to behave extremely well for variable selection in regression; a consequence of our results is that for intrinsic priors Lindley's paradox does not arise.

A Lattice Boltzmann study of flow along patterned surfaces and through channels with alternating slip length

description: In microfluidics, varying wetting properties, expressed in terms of the local slip length, can be used to influence the flow of a liquid through a device. We study flow past surfaces on which the slip length is modulated in stripes. We find that the effective slip length for such a flow can be expressed as a function of the individual slip lengths on the stripes. The angle dependence of the effective slip is in excellent agreement with a recent theory describing the slip length as a tensorial quantity. This tensorial nature allows to induce a transverse flow, which can be used in micro mixers to drive a vortex. In our simulations of a flow through a square channel with patterned surfaces we see a homogeneous rotation about the direction of the flow. We investigate the influence of patterns of cosine shaped varying local slip on the flow field depending on the orientation of the pattern and find the largest effective slip length for periods of stripes parallel to the flow direction.

description: Modeling the variability of the solar spectral irradiance is a key factor for understanding the solar influence on the climate of the Earth. As a first step to calculating the solar spectral irradiance variations we reproduce the solar spectrum for the quiet Sun over a broad wavelength range with an emphasis on the UV. We introduce the radiative transfer code COSI which calculates solar synthetic spectra under conditions of non-local thermodynamic equilibrium (NLTE). A self-consistent simultaneous solution of the radiative transfer and the statistical equation for the level populations guarantees that the correct physics is considered for wavelength regions where the assumption of local thermodynamic equilibrium (LTE) breaks down. The new concept of iterated opacity distribution functions (NLTE-ODFs), through which all line opacities are included in the NLTE radiative transfer calculation, is presented. We show that it is essential to include the line opacities in the radiative transfer to reproduce the solar spectrum in the UV. Through the implemented scheme of NLTE-ODFs the COSI code is successful in reproducing the spectral energy distribution of the quiet Sun.

description: A key aspect of farm management is decision making and a variety of methods to assist with decision making are widely used in commercial agriculture, ranging from simple budgets through to complex computer models. The vast majority of the worldsâ€™ farmers however have relatively small units of land and are in developing countries. It is widely accepted that these farmers make rational decisions within the challenging, complex, and risky environments that they operate. Despite major training and dissemination initiatives over many years, supported by national governments and international organisations to encourage farmers and extension staff to use farm management budgeting methods, uptake has remained extremely low. This paper reports on a research project funded by the UK Department for International Development, that firstly identified what small-scale farmers wanted from decision making methods and then worked with farmers and advisors in Ghana and Zimbabwe to develop and evaluate new and appropriate methods. These methods, in particular participatory budgets, have subsequently been successfully used in a range of developing countries. Results from activities conducted to evaluate participatory budgets are presented together with experience of their use for a variety of farm management functions, including planning and decision making. The findings demonstrate that they provide a useful method for small-scale and for non and semi-literate farmers operating in challenging environments, as well as for extension and research staff working with them.

description: Recreational leases for hunting, fishing, and wildlife watching provide a means by which landowners can supplement their income from land ownership. The income from recreational use is likely to provide incentives to conserve and manage land characteristics that enhance wildlife habitat hence biodiversity. Illinois professional farm managers were surveyed regarding recreational leases held by their clients. Information was collected on the extent of recreational leases or lack of, lease rates, recreational uses, types of wildlife, land management practices, and property characteristics. Results indicated that 38% of managers had recreational leases on about 6% of their managed properties. Average lease rates ranged from $9 to $38 per hectare depending upon the quality of the recreational property. Landowners on 55% of the properties adopted land management practices to enhance wildlife habitat. Results of a hedonic lease rate model indicated adoption of those land management practices positively affected lease rates.

title: Skeletal growth ring microanalysis and growth rates in sea pens from the Laurentian Channel MPA, Newfoundland
Creators: name: Greeley, Krista
Publisher: name: Memorial University of Newfoundland

description: Valuable information can be obtained through sea pen skeletons due to their high longevities and their annually deposited growth rings. Using Scanning Electron Microscopy with Energy Dispersive X-Ray Analysis (SEM-EDX), elemental microanalyses were performed on sea pen skeletons to understand the physical basis of their growth rings. Here, the elemental composition and structure of growth bands in Anthoptilum grandiflorum, Anthoptilum murrayi, Pennatula aculeata, Funiculina quandrangularis, Protoptilum carpenteri, and Kophobelemnon stelliferum are shown. Samples were collected using the remotely operated vehicle (ROV) ROPOS in 2017 from the Laurentian Channel marine protected area (MPA) at depths of 400-600 m. Cross-sections of the axes were examined using SEM-EDX, presenting minor element variations within each growth ring (light: 2.64 cps Mg, 47.5 cps Ca; dark: Mg 2.25 cps, Ca 51.2 cps). The data suggests primary differences include large, abundant voids in dark growth rings, and fewer smaller voids in the light growth rings.

description: We construct a Dark Matter (DM) annihilation module that can encompass the predictions from a wide array of models built to explain the recently reported PAMELA and ATIC/PPB-BETS excesses. We present a detailed analysis of the injection spectrums for DM annihilation and quantitatively demonstrate effects that have previously not been included from the particle physics perspective. With this module we demonstrate the parameter space that can account for the aforementioned excesses and be compatible with existing high energy gamma ray and neutrino experiments. However, we find that it is relatively generic to have some tension between the results of the HESS experiment and the ATIC/PPB-BETS experiments within the context of annihilating DM. We discuss ways to alleviate this tension and how upcoming experiments will be able to differentiate amongst the various possible explanations of the purported excesses.

description: Surface spontaneous parametric down-conversion is predicted as a consequence of continuity requirements for electric- and magnetic-field amplitudes at a discontinuity of chi2 nonlinearity. A generalization of the usual two-photon spectral amplitude is suggested to describe this effect. Examples of nonlinear layered structures and periodically-poled nonlinear crystals show that surface contributions to spontaneous down-conversion can be important.

description: To improve the trustworthiness of an AI model, finding consistent, understandable representations of its inference process is essential. This understanding is particularly important in high-stakes operations such as weather forecasting, where the identification of underlying meteorological mechanisms is as critical as the accuracy of the predictions. Despite the growing literature that addresses this issue through explainable AI, the applicability of their solutions is often limited due to their AI-centric development. To fill this gap, we follow a user-centric process to develop an example-based concept analysis framework, which identifies cases that follow a similar inference process as the target instance in a target model and presents them in a user-comprehensible format. Our framework provides the users with visually and conceptually analogous examples, including the probability of concept assignment to resolve ambiguities in weather mechanisms. To bridge the gap between vector representations identified from models and human-understandable explanations, we compile a human-annotated concept dataset and implement a user interface to assist domain experts involved in the the framework development.

The effects of alcohol consumption and expectancy on anxiety in men and women
Creators: name: Pullen, DJ
Publisher: name: University Of Tasmania

description: Literature review. Experimental research investigating the effects of alcohol consumption on anxiety has been equivocal, and alcohol consumption has been found to increase and decrease anxiety and also to have no effect on anxiety. These results are further complicated by evidence of significant sex differences in the effects of alcohol expectancy on anxiety. In this review, several theoretical models of the effects of alcohol are evaluated for their utility in explaining the relationship between alcohol and anxiety. Then, research utilising the balanced placebo design to investigate the relationship between alcohol and anxiety is reviewed, and the influence of pharmacological mechanisms, alcohol expectancy, and sex differences discussed. Finally, issues involved in defining and measuring anxiety are considered, and methodological limitations are presented as partially explaining the perplexing results in the area. Empirical study. The present study was conducted to determine the influence of pharmacological and expectancy mechanisms on simple reaction time and self report anxiety of men and women in a task designed to provoke performance anxiety. Ten male and ten female social drinkers participated in a 2 (sex) x 2 (alcohol expectancy) x 2 (beverage content) factorial balanced placebo study. The between subjects design generally used in balanced placebo research was replaced by a within subjects design, involving each participant completing four experimental sessions. Although results showed no significant effect of alcohol consumption, alcohol expectancy, or sex on self report anxiety, a number of trends were evident for self report anxiety. Firstly there was a trend suggesting that overall women were more anxious than men. Secondly an interaction between pre/post anxiety and instructional manipulation for both male and female anxiety responses approached significance. People who were told that they were receiving alcohol were more anxious following drink consumption than before drink consumption regardless of whether there was any alcohol in their beverage or not. No significant main effects for alcohol consumption, expectancy or sex were seen for reaction times to hits or false alarms, or to numbers of hits and misses.
