The Sign Test with Ties Included  [PDF]
Jennings B. Marshall
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.510152
Abstract:

The sign rank test is taught in virtually all introductory Statistics classes. When teaching the sign rank test the students are told to ignore the ties. Ignoring ties that support the null hypothesis is not logical. Why should valid data that support the null hypothesis be ignored? The approach taken here demonstrates a method for testing with ties included. A typical problem presentation in a text book would indicate that if you had ten ties in a sample of size fifty the tie scores would be excluded. However, the ten tie scores are a very valuable piece of statistical information which should not be ignored. The method demonstrated here shows that a different conclusion is reached in some cases when the ties are not excluded. Further many sign tests often will have ties because in some cases the data are not a cardinal number, but an ordinal number chosen from a set often results in ties. The alternative approach uses a one-tailed distribution and considers both +’s and -'s separated. A two-tailed test for equal variances is done with a one-tail of an F distribution. This alternate approach to the sign test allows the use of important statistical information which has been ignored with the traditional sign rank test.

Effects of Tillage and Planting Methods on Narrow and Wide Row Cotton Production  [PDF]
Michael W. Marshall, Ahmad Khalilian
Agricultural Sciences (AS) , 2018, DOI: 10.4236/as.2018.97056
Abstract: Cotton (Gossypium hirsutum L.) is an economically important crop for the Southern United States. The southern US also has a long growing season suitable for double cropping a second crop after small grains; however, the harvest date for the small grains typically occurs after the optimum planting window for cotton which reduces yield potential. A relay intercropping system was developed at Clemson University that allows interseeding of cotton into standing wheat 2 to 3 weeks before harvest with interseeded cotton yields similar to the conventional mono-cropped cotton. Therefore, the objectives of this study were 1) to determine the optimum tillage and planting methods for narrow row (76-cm) and wide row (97-cm) cotton, and 2) to compare narrow and wide row systems for conventional tillage cotton, cotton interseeded into standing wheat, and cotton planted into a terminated wheat cover crop on coastal plain soil. Two replicated tests were conducted to accomplish these objectives. In Study 1, conventional narrow row cotton combined with a deep tillage operation using Paratill yielded 23% more than conventional wide row cotton which had a deep tillage operation with a subsoiler just before planting. There were no differences between the conventional (97-cm row spacing) mono-crop and interseeded cotton yields. In Study 2, there was no significant difference in yield between narrow-row and wide-row cotton for each cropping system during the two years study. Both wide and narrow-row full season cotton had significantly higher yields than interseeded and cover crop planting systems in year two of the study. The two conservation cropping practices, wheat used as a cover crop and interseeding, showed considerable promise for reducing energy requirements, soil erosion, and wind-borne cotton damage associated with bare soil in conventional tillage. This research demonstrates the benefits of interseeding and narrow row spacing for sustainable cotton production in coastal plain soils of the Southern United States.
Identification of patients for clinical risk assessment by prediction of cardiovascular risk using default risk factor values
Tom Marshall

Abstract: Prior estimates of Framingham cardiovascular risk were derived in a population obtained from the Health Survey for England 2003. Receiver operating characteristics curves were constructed for using a prior estimate of cardiovascular risk to identify patients at greater than 20% ten-year cardiovascular risk. This was compared to strategies using age, or diabetic and antihypertensive treatment status to identify high risk patients.The area under the curve for a prior estimate of cardiovascular risk calculated using minimum data (0.933, 95% CI: 0.925 to 0.941) is significantly greater than for a selection strategy based on age (0.892, 95% CI: 0.882 to 0.902), or diabetic and hypertensive status (0.608, 95% CI: 0.584 to 0.632).Using routine data held on primary care databases it is possible to identify a population at high risk of cardiovascular disease. Information technology to help primary care prioritise patients for cardiovascular disease prevention may improve the efficiency of cardiovascular risk assessment.Because they are at high risk of cardiovascular events, patients with cardiovascular disease are the highest priority for preventive interventions. Some patients without cardiovascular disease are also at high risk and are the next priority for prevention. In patients without cardiovascular disease, the Framingham cardiovascular equation is widely used to determine probability of a cardiovascular event [1]. UK guidelines recommend treatment at a ten-year Framingham cardiovascular (CVD) risk of 20% [2]. Calculating Framingham cardiovascular risk requires knowledge of a patient's age, sex, diabetic status, smoking status, total cholesterol, HDL cholesterol and whether or not they have existing cardiovascular disease. Risk factor assessment requires patient time, staff time and laboratory tests. Furthermore, not all patients assessed are eligible for treatment. To make best use of resources for identification of patients eligible for preventive treatments it woul
O "pessimismo sentimental" e a experiência etnográfica: por que a cultura n?o é um "objeto" em via de extin??o (parte I)
Sahlins, Marshall;
Mana , 1997, DOI: 10.1590/S0104-93131997000100002
Abstract: this article (published in two parts) examines and refutes critiques of the concept of culture. the post-modernist identification of "culture" with colonialism and imperialism is a false diagnosis: marked by its reaction to enlightenment universalism, the historico-idelogical context within which the idea of culture took shape indicates the opposite. in turn, anxieties over the imminent end of human cultural variety are revealed to be foundless: globalisation and others capitalist phenomena, far from imposing a monotonous hegemony on the planet, have generated a historically unprecedent diversity of cultural forms and contents.

El Consumo Eléctrico Residencial en Chile en 2008
Marshall,Daniela;
Cuadernos de economía , 2010, DOI: 10.4067/S0717-68212010000100003
Abstract: this paper analyses the causes of the unusual drop in electricity consumption in households in chile during 2008. changes in income, the price of energy and the price of the substitute explain 8% of the actual drop in consumption. over 50% of the fall is explained by two of the measures taken by the government: the energy-saving campaign and the planned reduction in the nominal voltage. other measures included electricity saving rebates and changing the daylight saving time. had the authority not taken these measures the price of electricity would have had to rise 15% more to induce a similar reduction of household?s consumption.
All That Is Solid Melts into Air — Afterword 2010
Marshall Berman
Globality Studies Journal : Global History, Society, Civilization , 2010,
Abstract: When I first imagined All That Is Solid, my vision had an enormous scope: a cosmopolitan horizon that could embrace not only my neighborhood but also the whole world, and help empower men and women everywhere. When the book came out, in 1982, its American publisher was uninterested, and took it out of circulation. However, it was picked up by Verso, and then translated into many languages. It evoked great excitement in Brazil and Latin America, as part of the democratic culture that was just emerging after a generation of “dirty wars.” American Penguin noted this, and brought it out in an edition still in print. The book also had adventures in China, and most recently in Iran. The global reach of my earliest fantasies has come true.
Indonesia’s Jemek Supardi: From pickpocket to mime artist
Marshall Clark
Bijdragen tot de Taal-, Land- en Volkenkunde , 2011,
Abstract: Indonesia’s leading mime artist, Jemek Supardi, is a former pickpocket and grave-digger. Based in the key centre of Indonesian performative arts, the city of Yogyakarta, Central Java, Jemek is an active member of several artistic troupes and he is a collaborator, friend and acquaintance of many within the closely-knit arts-scene, which in terms of diversity and sheer volume of performances, is unique in Indonesia. Although mime is a niche art-form in Indonesia, Jemek’s self-taught skill as a pantomime artist is clearly evident and his reputation as a professional is second-to-none, particularly in Yogyakarta. This article examines key elements of Jemek’s performative milieu, including his use of mime and silence as a mode of cultural and political expression and his use of white face-paint as an expression of solidarity with the Javanese proletariat. The link between the personal and political elements of Jemek’s artistic practice will also be examined, simultaneously highlighting the difficulty of applying any particular theoretical template onto his life and art.
Innate rights and just relations 1
Paul Marshall
Koers : Bulletin for Christian Scholarship , 1991, DOI: 10.4102/koers.v56i2.737
Abstract: Currently the terms rights is and human rights are used to refer to two types of entities. One is a kind of legal claim or guarantee given in positive law. The other is a purported moral claim or interest implicit in the nature of human persons. A peculiar feature of modem discussions of rights is that these diverse things are commonly treated as if they had some necessary relation to one another. In fact, historically and conceptually, they do not and the frequent attempts to relate them can have inimical results. It can confuse substantive human rights with the promulgation of an individualist view of the person. The defence of human rights (of the types now mentioned in international treaties) would be helped by divorcing these from a notion of innate rights and, instead, understanding rights as legal guarantees of just political relations.

Marshall, Francisco
Letras de Hoje , 2009,
Abstract: Este artigo parte do diagnóstico da crise histórica e cultural que abalou a credibilidade do mito, tal como expresso na épica de Homero e Hesíodo, na Grécia arcaica, e avan a ilustrando as diferentes tentativas de se explicar ou justificar o mito. Por esta raz o, o artigo é uma história do surgimento e desenvolvimento do conceito de “alegoria”, como categoria interpretativa do mito, e sua aplica o na antiguidade, na renascen a e na atualidade.
