Seeking to preserve electronically encoded evidence implies that an incident or event has occurred requiring fact extrapolation for presentation, as proof of an irregularity or illegal act. Whether target data are in transit or at rest, it is critical that measures be in place to prevent the sought information from being destroyed, corrupted or becoming unavailable for forensic investigation.

This essay uses a mental files theory of singular thought—a theory saying that singular thought about and reference to a particular object requires possession of a mental store of information taken to be about that object—to explain how we could have such thoughts about abstract mathematical objects. After showing why we should want an explanation of this I argue that none of three main contemporary mental files theories of singular thought—acquaintance theory, semantic instrumentalism, and semantic cognitivism—can give it. I argue (...) for two claims intended to advance our understanding of singular thought about mathematical abstracta. First, that the conditions for possession of a file for an abstract mathematical object are the same as the conditions for possessing a file for an object perceived in the past—namely, that the agent retains information about the object. Thus insofar as we are able to have memory-based files for objects perceived in the past, we ought to be able to have files for abstract mathematical objects too. Second, at least one recently articulated condition on a file’s being a device for singular thought—that it be capable of surviving a certain kind of change in the information it contains—can be satisfied by files for abstract mathematical objects.

Cyber attackers targeting large corporations achieved a high perimeter penetration success rate during 2013, resulting in many corporations incurring financial losses. Corporate information technology leaders have a fiduciary responsibility to implement information security domain processes that effectually address the challenges for preventing and deterring information security breaches. Grounded in corporate governance theory, the purpose of this correlational study was to examine the relationship between strategic alignment, resource management, risk management, value delivery, performance measurement implementations, and information security governance (ISG) effectiveness (...) in United States-based corporations. Surveys were used to collect data from 95 strategic and tactical leaders of the 500 largest for-profit United States headquartered corporations. The results of the multiple linear regression indicated the model was able to significantly predict ISG effectiveness, F(5, 89) = 3.08, p = 0.01, R² = 0.15. Strategic alignment was the only statistically significant (t = 2.401, p <= 0.018) predictor. The implications for positive social change include the potential to constructively understand the correlates of ISG effectiveness, thus increasing the propensity for consumer trust and reducing consumers' costs.

Until recently, psychologists have conceptualised and studied trust in God (TIG) largely in isolation from contemporary work in theology, philosophy, history, and biblical studies that has examined the topic with increasing clarity. In this article, we first review the primary ways that psychologists have conceptualised and measured TIG. Then, we draw on conceptualizations of TIG outside the psychology of religion to provide a conceptual map for how TIG might be related to theorised predictors and outcomes. Finally, we provide a research (...) agenda for future empirical work in this area, as well as practical applications for counsellors and religious leaders. (shrink)

After introducing the new field of cultural evolution, we review a growing body of empirical evidence suggesting that culture shapes what people attend to, perceive and remember as well as how they think, feel and reason. Focusing on perception, spatial navigation, mentalizing, thinking styles, reasoning (epistemic norms) and language, we discuss not only important variation in these domains, but emphasize that most researchers (including philosophers) and research participants are psychologically peculiar within a global and historical context. This rising tide of (...) evidence recommends caution in relying on one’s intuitions or even in generalizing from reliable psychological findings to the species, Homo sapiens. Our evolutionary approach suggests that humans have evolved a suite of reliably developing cognitive abilities that adapt our minds, information-processing abilities and emotions ontogenetically to the diverse culturally-constructed worlds we confront.

I reconcile the spatiotemporal location of repeatable artworks and impure sets with the non-location of natural numbers despite all three being varieties of abstract objects. This is possible because, while the identity conditions for all three can be given by abstraction principles, in the former two cases spatiotemporal location is a congruence for the equivalence relation featuring in the relevant principle, whereas in the latter it is not. I then generalize this to other ‘physical’ properties like shape, mass, and causal (...) powers. (shrink)

Product-harm crisis is an important organizational management topic due to the potential detrimental business impact. Organizations are more vulnerable than ever to the possibility of product related incidents disrupting business at any point in the supply chain. To counteract this implicit threat to an organizations reputation and financial wellbeing, if properly deployed, continuity management fosters the ability to run in the face of a crisis event; whereby business continuity management induces the means for appropriate product-harm crisis responses. In this study, (...) the author synthesizes selected published research presenting product-harm crisis management considerations. Based on an assigned literature review; the author summarizes article content, compares and contrasts methods and extrapolates results and conclusions garnered from the selected scholarly research; then provides an actionable recommendation for enabling effective product-harm crisis management.

In the wake of the recent financial crisis, increasing the effectiveness of auditing has weighed heavily on the minds of those responsible for governance. When a business is profitable and paying healthy dividends to its stockholders, fraudulent activities and accounting irregularities can go unnoticed. However, when revenue and cash flow decline, internal costs and operations may be scrutinized more diligently, and discrepancies can emerge as a result. Effective Auditing for Corporates provides you with proactive advice to ...

Through detailed analysis of Plato’s Meno, I identify and set general argumentative rules (useful both to scientists and philosophers) concerning how to use definitions. I show how the character Socrates establishes strong requirements for knowledge in general, i.e., that the knowledge of the definition of a thing must be prior to the knowledge of properties or instances of that thing. Socrate’s requirements and the way he characterizes a definition (as coextensive to the definiendum, not circular, true and explanatorily relevant) lead (...) Meno to aporia and to enunciate the famous Meno’s Paradox concerning the impossibility of inquiry for knowledge. That only occurs because Meno is unable to identify Socrate’s dialectical move: strong requirements for knowing a definition, the priority of the knowledge of the definition and the taking of all knowledge to be like the knowledge by acquaintance. After the paradox, Socrate’s proceeds the discussion using hypotheses to map the truth conditions of some theses Meno is inquiring about. I explain what are Meno’s paradox, the socratic definition and the Method of Hypotheses, in a way só as to find in this classical text in the history of philosophy general principles of argumentation that are still usefull today.

I defend an interpretation of Aristotle’s Posterior Analytics Book I which distinguishes between two projects in different passages of that work: (i) to explain what a given science is and (ii) to explain what properly scientific knowledge is. I present Aristotle’s theory in answer to ii, with special attention to his definition of scientific knowledge in 71b9-12 and showing how this is developed on chapters I.2-9 and I.13 into a solid Theory of Scientific Demonstration. The main point of this theory (...) is that demonstrations need to capture relevant explanations. Some formal requirements of the demonstration (as the syllogistic structure and coextension between terms) are unfoldings of the main project, i.e., to capture and present properly relevant causal-explanatory relations.

It's sometimes thought that context-invariant linguistic meaning must be a character (a function from context types to contents) i.e. that linguistic meaning must determine how the content of an expression is fixed in context. This is thought because if context-invariant linguistic meaning were not a character then communication would not be possible. In this paper, I explain how communication could proceed even if context-invariant linguistic meaning were not a character.

“Critical thinking in higher education” is a phrase that means many things to many people. It is a broad church. Does it mean a propensity for finding fault? Does it refer to an analytical method? Does it mean an ethical attitude or a disposition? Does it mean all of the above? Educating to develop critical intellectuals and the Marxist concept of critical consciousness are very different from the logician’s toolkit of finding fallacies in passages of text, or the practice of (...) identifying and distinguishing valid from invalid syllogisms. Critical thinking in higher education can also encompass debates about critical pedagogy, i.e., political critiques of the role and function of education in society, critical feminist approaches to curriculum, issues related to what has become known as critical citizenship, or any other education-related topic that uses the appellation “critical”. Equally, it can, and usually does, refer to the importance and centrality of developing general skills in reasoning—skills that we hope all graduates possess. Yet, despite more than four decades of dedicated scholarly work “critical thinking” remains as elusive as ever. As a concept, it is, as Raymond Williams has noted, a ‘most difficult one’ (Williams, 1976, p. 74). (shrink)

Bystander information is information about others’ attitudes towards a text (i.e. about whether they agree or disagree with it). Social media platforms force bystander information upon us when we read posts thereon. What effect does this have on how we respond to what we read? The dominant view in the literature is that it changes our minds (the so-called “bandwagon effect”). Simplifying a little: if we see that most people agree (disagree) with what a post says, we are more likely (...) to agree (disagree) with what it says. This paper argues that we should take seriously a competitor view and care about the difference between it and the dominant view. The competitor view proposes that bystander information changes what a text seems to us to say: although bystander information may lead us to change what attitude we express toward a post, that’s not because we’ve changed our attitude toward any fixed content (i.e. fixed thing that the post says). This paper argues that, if this competitor view is correct, then social media is likely to be an especially hazardous place for the practice of sharing content. (shrink)

This is the English (and extended version) of an interview originally published in Estonian in October 2018.

In ‘The Pregnancy Rescue Case: why abortion is immoral’, Hendricks presents The Pregnancy Rescue Case. In this reply I argue that even if it would be better (i.e., less bad) for the abortion to be prevented in The Pregnancy Rescue Case, that does not mean that typical abortions are impermissible. I also argue that there is a possible explanation, consistent with the pro-choice view and empirically testable, as to why people would think it better for the abortion to be prevented (...) in The Pregnancy Rescue Case.

defining art conjunctively, that is, by defining the individual arts and joining these definitions in an exhaustive list. I suggest that the individual art forms are no easier to define than is the general category of art. As well, not everything falling within a given art form counts as art, not every instance of art in the given medium falls within the art form, and some artworks do not belong to an art form at all, so conjoining definitions of the (...) individual art forms (supposing they could be defined) would not map the extension of ’art’. Taken together, these problems indicate that the approach advocated here to art’s definition cannot be successful or convincing. (shrink)

A set D subset of V(G) is a dominating set of a graph G if for all x ϵ V(G)\D, for some y ϵ D such that xy ϵ E(G). A dominating set D subset of V(G) is called a connected dominating set of a graph G if the subgraph <D> induced by D is connected. A connected domination number of G, denoted by γ_c(G), is the minimum cardinality of a connected dominating set D. The triple repetition sequence denoted by (...) {S_n:n ϵ Z+} is a sequence of positive integers which is repeated thrice, i.e., {S_n}={1,1,1,2,2,2,3,3,3, ...}.

Why should a person, and in the context of this conference particularly an art historian, take seriously the notion of the aesthetic, its discovery and/or rediscovery? Aesthetics might after all be considered at best something of a distraction from bread and butter historical and sociological analysis, and at worst entirely incompatible with it. Pursuing the line further it might be urged that, since on the one hand aesthetics is about 'how things appear'—i.e. is subject to individual predilection, taste and feeling—and (...) on the other, historical analysis is about the careful and scholarly reconstruction of a past social reality, the two must be at loggerheads. What the art historian writes about on a weekday whilst wearing her hard hat at the office must not be confused with what she personally feels, wandering around a gallery in her woolly hat at the weekend.

This chapter reviews empirical evidence bearing on the design of online forums for deliberative civic engagement. Dimensions of design are defined for different aspects of the deliberation: its purpose, the target population, the spatiotemporal distance separating participants, the communication medium, and the deliberative process to be followed. After a brief overview of criteria for evaluating different design options, empirical findings are organized around design choices. Research has evolved away from treating technology for online deliberation dichotomously (either present or not) toward (...) nuanced findings that differentiate between technological features, ways of using them, and cultural settings. The effectiveness of online deliberation depends on how well the communicative environment is matched to the deliberative task. Tradeoffs, e.g. between rich and lean media and between anonymous and identifiable participation, suggest different designs depending on the purpose and participants. Findings are limited by existing technologies, and may change as technologies and users co-evolve. (shrink)

The study of biodiversity spans many disciplines and includes data pertaining to species distributions and abundances, genetic sequences, trait measurements, and ecological niches, complemented by information on collection and measurement protocols. A review of the current landscape of metadata standards and ontologies in biodiversity science suggests that existing standards such as the Darwin Core terminology are inadequate for describing biodiversity data in a semantically meaningful and computationally useful way. Existing ontologies, such as the Gene Ontology and others in the Open (...) Biological and Biomedical Ontologies (OBO) Foundry library, provide a semantic structure but lack many of the necessary terms to describe biodiversity data in all its dimensions. In this paper, we describe the motivation for and ongoing development of a new Biological Collections Ontology, the Environment Ontology, and the Population and Community Ontology. These ontologies share the aim of improving data aggregation and integration across the biodiversity domain and can be used to describe physical samples and sampling processes (for example, collection, extraction, and preservation techniques), as well as biodiversity observations that involve no physical sampling. Together they encompass studies of: 1) individual organisms, including voucher specimens from ecological studies and museum specimens, 2) bulk or environmental samples (e.g., gut contents, soil, water) that include DNA, other molecules, and potentially many organisms, especially microbes, and 3) survey-based ecological observations. We discuss how these ontologies can be applied to biodiversity use cases that span genetic, organismal, and ecosystem levels of organization. We argue that if adopted as a standard and rigorously applied and enriched by the biodiversity community, these ontologies would significantly reduce barriers to data discovery, integration, and exchange among biodiversity resources and researchers.

Despite the ubiquity of bees in Dickinson’s work, most interpreters denigrate her nature poems. But following several recent scholars, I identify Nietzschean/Dionysian overtones in the bee poems and suggest the figure of bees/hive/queen illuminates as feminist key to her corpus. First, (a) the bee’s sting represents martyred death; (b) its gold, immortality; (c) its tongue, the “lesbian phallus”; (d) its wings, poetic power; (e) its buzz, poetic melody, and (f) its organism, a joyful Dionysian Susan (her sister-in-law and love interest) (...) to Emily’s flower. Second, the hive represents her individual poems (with slants/dashes as stingers, wings as hymn meter, honey as rhymes, variant words as exiled bees, and accompanying flowers their Darwinian coevolution with bees), constituting her writing persona as a multi-voiced self-swarm, as organized in the apiary of her letters and fascicles. And third, the queen represents her Western cultural and religious inheritance wherein bees are symbols of the soul, reincarnation, poetic-philosophical vocation, and a Nietzschean, trans-Dionysian naturalist ontology—symbolized by apiarian Artemis.

In response to Stephen Davis’s criticism of our previous essay, we revisit and defend our arguments that the Resurrection hypothesis is logically incompatible with the Standard Model of particle physics—and thus is maximally implausible—and that it cannot explain the sensory experiences of the Risen Jesus attributed to various witnesses in the New Testament—and thus has low explanatory power. We also review Davis’s reply, noting that he evades our arguments, misstates their conclusions, and distracts the reader with irrelevancies regarding, (...) e.g., what natural laws are, what a miracle is, and how “naturalism” and “supernaturalism” differ as worldviews. Contrary to what Davis claims (even in his abstract), we do not argue that “if the Standard Model of particle physics is true, then the resurrection of Jesus did not occur and physical things can only causally interact with other physical things.” Davis distorts our claims and criticizes straw men of his own creation.

A response to critical commentaries. Crookston begins her commentary by noting that my book would have been better with answers to “the following three questions: (1) Why is the harm principle the right principle upon which to base a theory of toleration? (2) How is Cohen thinking of the concept of volenti? (p. x ) Is interference (i.e., the abandonment of toleration) ever morally required by the harm principle?” (p. x ). She is right, and I address these questions below (...) in Sections 2, 3, and 4. That is the bulk of this essay. I then turn to Kelley's issues in Sections 6, 7, and 8; these have to do with “the link between toleration and relativism,” the way I distinguish “the concepts of toleration and endurance,” and a “question about moral toleration” (p. x ). Despite much agreement, there are points of contention and I try to make my position clearer in response . (shrink)

PRINCÍPIOS DA DIGESTÃO DOS ALIMENTOS NOS BEZERROS -/- -/- E. I. C. da Silva -/- Departamento de Agropecuária – IFPE Campus Belo Jardim -/- Departamento de Zootecnia – UFRPE sede -/- -/- PRINCÍPIOS DA DIGESTÃO DOS ALIMENTOS NOS BEZERROS -/- -/- INTRODUÇÃO -/- Se todos os bezerros pudessem ser criados por suas mães, haveria pouca necessidade de inúmeros livros, artigos e trabalhos, como esse, sobre a criação e o manejo básico desses animais. A maioria das vacas desempenha um ótimo papel (...) na criação dos seus descendentes, desde que sejam tomados os devidos cuidados com relação a alimentação, saúde e a outros aspectos relativos à criação desses neonatos. A essência da pecuária bovina relativa à criação de bezerros é manter esses animais vivos e aptos o suficiente para desempenhar atividades produtivas de grande importância na propriedade. Para tanto, os criadores necessitam entender o desenvolvimento do trato digestivo do bezerro e os conceitos básicos da digestão dos alimentos por ele, e é isso que pretendo aclarar de forma clara e concisa com esse trabalho. -/- -/- 1.1 O TRATO DIGESTIVO DO BEZERRO -/- Um animal adulto necessita de quatro estômagos funcionais para dar-lhe a capacidade de utilizar a ampla gama de alimentos disponíveis. -/- O retículo e o rúmen abrigam milhões de micróbios que fermentam e digerem o material vegetal, em especial às presentes nas forragens. O omaso permite a absorção de água do conteúdo do intestino. O abomaso, ou quarto estômago, é o verdadeiro estômago, comparável ao dos humanos, e permite a digestão ácida dos alimentos. -/- O bezerro muito jovem não desenvolve a capacidade de digerir o pasto, sendo assim o abomaso é o único estômago funcional ao nascer. Tanto os animais recém-nascidos como os adultos têm um intestino delgado funcional que permite a digestão alcalina dos alimentos. -/- A figura 1 ilustra a anatomia dos estômagos e intestino delgado de um bezerro recém-nascido. Esse diagrama esquemático mostra as dimensões relativas dos quatro estômagos, o sulco esofágico, que vai do esôfago até o abomaso, e o esfíncter pilórico ou válvula no fundo do abomaso, que controla a velocidade de movimento do conteúdo do intestino no duodeno. -/- O omaso e o abomaso representam cerca de 70% da capacidade total do estômago no bezerro recém-nascido. Por outro lado, nas vacas adultas, eles compõem apenas 30% da capacidade total do estômago (figura 2). -/- A digestão dos alimentos é auxiliada pela secreção de certos produtos químicos denominados enzimas, que estão presentes nas várias partes do intestino. Por exemplo, os bezerros produzem a enzima renina na parede do abomasal para auxiliar na digestão das proteínas do leite, enquanto a lactase é produzida na parede do duodeno para a digestão do açúcar do leite (lactose). Estas enzimas operam mais eficazmente em diferentes níveis de acidez no conteúdo do intestino, ácido no abomaso e alcalino no duodeno. Para conseguir isso, o bezerro segrega eletrólitos, ou sais minerais, com as enzimas, para mudar o conteúdo do intestino de um tipo para outro. -/- Os produtos finais da digestão dos diferentes componentes dos alimentos são absorvidos através da parede do intestino, mediante as vilosidades intestinais, para a corrente sanguínea, onde são levados para as diferentes partes do corpo para o crescimento e desenvolvimento do animal. -/- -/- 1.2 O BEZERRO ALIMENTADO COM LEITE -/- O Leite ou substituto do leite, quer seja apreendido através de uma teta ou bebido de um balde, é canalizado do esôfago através do sulco esofágico para o abomaso. Este sulco é um pequeno canal na parede do rúmen que é controlado por músculos que permitem que os líquidos sejam diretamente enviados para o abomaso e que não entrem no rúmen. O sulco é ativado em resposta a diferentes estímulos. Funciona bem quando os bezerros amamentam-se através das tetas das mães, mas às vezes não funciona quando bebem de um balde. Essa parece ser uma condição psicológica em resposta aos bezerros separados de suas mães. A maioria dos bezerros podem ser treinados pelo tratador para beber o leite do balde rapidamente e bem, a metodologia empregada é a da persuasão do animal, ao qual o mesmo possa responder positivamente à nova rotina diária e à mãe substituta na forma do criador do bezerro. Quando o leite ou o substituto do leite entra no abomaso, forma um coágulo firme dentro de alguns minutos sob a influência das enzimas renina e pepsina. Este é o mesmo processo envolvido na fabricação de queijo ou junket, usando renina para coagular a proteína do leite. A coagulação do leite retarda a taxa em que flui para fora do abomaso, permitindo assim uma liberação constante de nutrientes alimentares em todo o intestino e, eventualmente, para a corrente sanguínea. Pode levar de 12 a 18 horas para que a coalhada de leite seja totalmente digerida. -/- As enzimas que atuam nas proteínas do leite requerem um ambiente ácido e esse é fornecido pela secreção do ácido clorídrico no abomaso. No entanto, até que a digestão ácida esteja operando de forma eficiente, e isso pode levar até sete dias, a única forma de proteína que pode ser digerida é a caseína. Não há substituto para a caseína no bezerro muito jovem. Os substitutos do leite que contêm outras formas de proteína não podem ser devidamente digeridos até que os bezerros sejam mais velhos. Logo, é necessário muito cuidado para não fornecer substitutos ou sucedâneos que contenham fontes proteicas que não possam ser digeridas pelo estômago do animal, para que não ocasione complicações gastrintestinais. -/- A digestão do leite pode ser melhorada com a inclusão de coalho, que pode ser obtido a partir de fábricas de queijo ou aditivos comerciais de leite de bezerro para a primeira semana ou mais. Esses produtos comerciais podem fornecer ácidos adicionais para reduzir o pH abomasal e incrementar a quantidade de enzimas e bactérias específicas para aumentar a taxa de degradação da coalhada de leite. Tais aditivos são chamados probióticos, na medida em que ajudam nos processos digestivos normais. A pesquisa nem sempre os encontrou para melhorar o desempenho e a saúde dos bezerros, e eles são mais propensos a ser benéficos quando os bezerros estão sofrendo de problemas de saúde. Além disso, a sua eficácia, em termos de custo-benefício é, por vezes, questionada. -/- Qualquer leite de uma alimentação anterior está envolvido neste coágulo recém-formado. As proteínas líquidas de soro de leite e a lactose são rapidamente separadas da coalhada de leite e passam para o abomaso. A gordura do leite contida na coalhada de leite é decomposta por outra enzima, a lipase. Esta é secretado na boca pela saliva e incorporada quando o leite é engolido. A alimentação pelas tetas em vez da alimentação através do balde parece produzir mais saliva e, portanto, mais lipase. A digestão adicional da proteína do leite e da gordura ocorre no duodeno com a ajuda das enzimas produzidas no pâncreas. -/- A lactose, que é rapidamente liberada da coalhada de leite no abomaso, é dividida em glicose e galactose e estas são absorvidas na corrente sanguínea para formar a principal fonte de energia para os bezerros jovens. -/- As gorduras são divididas em ácidos graxos e glicerol para absorção e uso como energia, enquanto as proteínas são divididas em aminoácidos e peptídeos para absorção e uso como fontes de proteína corporal. -/- O amido de cereais, por exemplo, é uma importante fonte de energia em bezerros mais velhos, mas esses animais, nas suas primeiras semanas de vida, não conseguem digerir o amido. -/- O abomaso não é ácido até que o bezerro tenha 1-2 dias de idade e isso apresenta vantagens e desvantagens. A principal vantagem é que as proteínas imunes no colostro não podem ser digeridas nesse compartimento estomacal, por isso são absorvidas na corrente sanguínea na mesma forma quando produzidas pela vaca. Isso garante o seu papel como anticorpos para proteger contra as doenças e infecções. A baixa acidez do conteúdo abomasal no bezerro recém-nascido constitui um risco potencial das bactérias (e provavelmente vírus) tomadas através da boca. Estes não serão mortos pela digestão ácida, sendo assim podem passar para os intestinos, onde podem fazer mal ao bezerro recém-nascido. -/- Todos os bezerros pegam bactérias nos primeiros dias de vida e isso é essencial para o desenvolvimento normal do rúmen (flora microbiana). No entanto, a primeira bactéria a colonizar o intestino também pode causar danos. Desde que o bezerro tenha bebido colostro, os anticorpos maternos podem controlar a propagação dessas bactérias mais nocivas. -/- O bezerro alimentado com leite deve, então, produzir uma digestão ácida no abomaso e uma digestão alcalina no duodeno. Isto é conseguido pela produção de eletrólitos na parede do intestino. -/- Bezerros que sofrem de escoriações devido a distúrbios nutricionais ou infecções bacterianas podem perder grandes quantidades de água e eletrólitos em suas fezes. Estes devem ser reabastecidos como parte do tratamento para as escoriações. -/- O colostro é o primeiro leite produzido por vacas recém-paridas. Além de fornecer nutrientes essenciais para a alimentação animal, fornece anticorpos maternos que permitem a transferência passiva de imunidade contra doenças. As recomendações para a alimentação com colostro serão abordadas brevemente em outro trabalho. -/- -/- 1.3 DESENVOLVIMENTO DO RÚMEN E O PROCESSO DE DESMAME -/- Quando os bezerros são desmamados, o custo da criação diminui acentuadamente. Os custos de alimentação são mais baixos, os insumos de trabalho são reduzidos e a incidência de problemas de saúde é menor. No sentido econômico, faz sentido desmamar os bezerros assim que for razoável. No entanto, o bezerro é forçado a sofrer várias mudanças dramáticas, a saber: -/-  A fonte primária de nutrientes muda de líquido para sólido. -/-  A quantidade de matéria seca que o bezerro recebe é reduzida. -/-  O bezerro deve adaptar-se de um tipo monogástrico a um ruminante de digestão, que inclui a fermentação de alimentos. -/-  Mudanças na habitação e no manejo muitas vezes ocorrem em torno do desmame, o que pode aumentar o estresse. -/- Ao nascer, o rúmen é uma parte pequena e estéril do intestino que, ao desmame deve se tornar o compartimento mais importante dos quatro estômagos. Deve aumentar em tamanho, atividade metabólica interna e fluxo sanguíneo externo. Os cinco requisitos para o desenvolvimento ruminal são: -/-  Estabelecimento de bactérias. -/-  Líquido. -/-  Saída de material (ação muscular). -/-  Capacidade absortiva do tecido. -/-  Substrato para permitir o crescimento bacteriano, tais como minerais reciclados, bem como nutrientes para alimentação. -/- Antes do consumo de alimentos sólidos, as bactérias existentes fermentam o cabelo ingerido, o estrato e o leite que flui do abomaso para o rúmen. A maior parte da água que entra no rúmen provém da água livre (água real não contida no leite ou na solução substituta do leite). O leite contornará o rúmen através do sulco esofágico, enquanto a água livre não. -/- O rúmen se desenvolve a partir de um órgão muito pequeno em bezerros recém-nascidos (1-2 L) para a parte mais importante do intestino (25-30 L) por 3 meses de idade. Ele pode aumentar muito rapidamente durante as primeiras semanas de vida, dado o manejo da alimentação direita. -/- O crescimento do rúmen ocorre apenas sob a influência dos produtos finais da digestão no mesmo, que resultam da fermentação de alimentos sólidos pelos micróbios presentes nesse compartimento. O desenvolvimento ocorre em grande parte através do crescimento das papilas ruminais (figura 5 e 6) na parede ruminal (estruturas semelhantes a folhas na superfície interna), que aumentam a área superficial do rúmen e, portanto, a sua capacidade de absorver estes produtos finais de digestão. Portanto, os concentrados favorecem melhor o desenvolvimento dessas papilas ruminais. Para tanto, é necessário, com um tempo, ir incrementando a dieta sólida gradativamente para que esses animais deixem de consumir o leite das vacas produtoras e possam alimentar-se de ração e pastagens, que é a finalidade da criação de bovinos, ou seja, criar animais com menor custo possível e engordá-los através de ração, mas principalmente de pastagens. -/- A capacidade do rúmen e a ingestão de alimentos sólidos estão intimamente relacionadas. O desenvolvimento do rúmen é muito lento em bezerros alimentados com grandes quantidades de leite. O leite satisfaz seus apetites para que eles não tenham fome suficiente para comer qualquer alimento sólido. Logo, é necessário diminuir paulatinamente o fornecedor do leite para esses animais, favorecendo a ingestão de alimentos sólidos e desenvolvendo o rúmen, estômago que digere as fibras das forragens e que os tona animais peculiares. -/- A ruminação pode ocorrer com cerca de 2 semanas de idade e é uma boa indicação de que o rúmen está se desenvolvendo. Alimentos sólidos, bem como a ruminação, estimulam a produção de saliva e isso fornece nutrientes como ureia e bicarbonato de sódio para produzir os substratos para o crescimento e desenvolvimento da flora bacteriana. -/- No desmame precoce, é importante limitar a quantidade de leite oferecida e a sua disponibilidade durante todo o dia. Também é essencial fornecer alimentos sólidos. Os grosseiros (de baixa ou alta qualidade) devem ser oferecidos em combinação com concentrados de alta qualidade. -/- O criador deve tomar cuidado com o fornecimento de alimentos como a ração farelada, uma vez que essa ração pode entrar pelas vias nasais e ocasionar complicações respiratórias; há alguns relatos de bezerros mortos após a ingestão de ração farelada, na autópsia de um dos casos foi diagnosticada uma morte por esses grãos farelados presentes no pulmão. Portanto, para evitar complicações o ideal é que se forneça uma ração denominada peletizada. -/- Os alimentos grosseiros (volumosos) estimulam o desenvolvimento do rúmen, enquanto os concentrados fornecem nutrientes para a alimentação animal que não são fornecidos pelas quantidades limitadas de leite oferecidas. Sem os concentrados, o crescimento dos bezerros é lento, mas o rúmen ainda se desenvolve, resultando em animais barrigudos. -/- A ureia fornece nitrogênio para os micróbios, enquanto o bicarbonato de sódio atua como um tampão ruminal, ajudando a manter um pH estável no conteúdo do rúmen. Isso é, particularmente, importante quando os bezerros comem grandes quantidades de grãos de cereais na vida adulta, pois os micróbios do rúmen podem produzir muito ácido lático durante a fermentação desse material. -/- Envenenamento por grãos ou acidose ocorre quando os níveis de ácido lático são excessivamente elevados e tornam-se tóxicos para os micróbios do rúmen e, eventualmente, para o animal. Assim como os produtos finais que são absorvidos através da parede do rúmen, a fermentação microbiana produz os gases dióxido de carbono e metano e estes são normalmente exalados. Quando algo impede a fuga destes gases do rúmen, o inchaço pode se manifestar em qualquer fase da vida, diz-se do animal estufado. -/- -/- 1.4 O PAPEL DA FORRAGEM NO PROCESSO DE DESMAME -/- Existem inúmeras controvérsias acerca do papel da forragem no processo de desmame. Pesquisas realizadas na década de 1980 indicaram claramente que a forragem era benéfica, enquanto pesquisas da década de 1990 descobriram que nem sempre era necessário o fornecimento da forragem para que os bezerros fossem desmamados e que não sofresse estresse e nem apresentasse baixa eficiência produtiva e reprodutiva no futuro. Na maioria das pesquisas anteriores, os bezerros eram desmamados com a oferta de concentrados moídos como pellets com ou sem a presença de feno longo ou palha. Porém, a inclusão de forragens na dieta melhorou a ingestão e o desempenho, além de permitir o desmame precoce. -/- Na pesquisa posterior, os bezerros geralmente alimentavam-se de concentrados grosseiramente moídos, além de alguns volumosos, enquanto alguns até incluíam volumosos picados finos na mistura (às vezes chamados de mistura muesli por apresentar o capim e a ração). Nesses estudos, verificou-se que a inclusão de feno ou palha adicional teve pouco efeito no desempenho pré-desmame. -/- Os sistemas de criação de bezerros australianos frequentemente diferem dos demais, especialmente em áreas de parto sazonais. Um número excessivo elevado de bezerros precisam ser criados de uma só vez para lhes fornecer, a todos, currais individuais durante todo o seu período de amamentação. Consequentemente, os bezerros são criados em grupos. Além disso, os ingredientes da maioria dos concentrados para esses animais são finamente moídos. Nessas situações, descobriu-se que a palha limpa é um alimento útil e que deve ser incluso no período pré-desmame. Alguns agricultores preferem feno de boa qualidade, porém estes agricultores geralmente têm bezerros em grupos muito pequenos, muitas vezes um ou dois, por isso possuem maior controle sobre a ingestão de forragem. -/- Figura 7: A alimentação volumosa de bezerros alimentados com leite é uma questão controversa. Imagem cedida pelo IPA -/- É difícil e, portanto, mais caro que os produtores de rações incorporem feno picado nas refeições dos bezerros. Os pellets são muito mais fáceis, pois eles vão fluir para silos. Por fim, os produtores de leite devem incluir o componente volumoso no regime alimentar pré-desmame. A pastagem não é a fonte ideal de forragem volumosa para os bezerros alimentados com leite, uma vez que possui muito pouca fibra e uma baixa densidade de energia alimentar. O seu elevado teor de água limita a sua capacidade de fornecer energia alimentar adequada aos animais em crescimento. Para ingerir a pastagem a capacidade ruminal deveria ser maior, bezerros jovens simplesmente não conseguem comer pasto suficiente, a menos que seja de alta em qualidade. -/- Os bezerros criados com leite e fornecimento gradual de concentrados apresentam uma boa função ruminal às 3 semanas de vida, além de possuírem uma suficiente capacidade ruminal para o desmame entre às 4-6 semanas de idade. No entanto, se a dieta for baseada em leite restrito e pastagem de alta qualidade, a capacidade do rúmen pode não ser suficiente para o desmame até às 8-10 semanas de vida. Mesmo assim, as taxas de crescimento seriam menores em bezerros desmamados com base alimentar somente à pasto, uma vez que a ingestão de energia é insuficiente devido às limitações físicas da capacidade ruminal. -/- Se a qualidade for muito boa e produza apetite, os bezerros preferem volumosos ao invés do concentrado, o que leva a uma ingestão reduzida de nutrientes durante alimentação, tendo como efeito um crescimento mais lento. Quando volumosos e concentrados fornecem apetite no animal, juntamente com o leite limitado, os bezerros podem comer cerca de 10% de palha e 90% de concentrados. Sem o volumoso e a ruminação resultante, o desenvolvimento do rúmen será mais lento devido à falta de saliva e produtos finais da digestão de fibras presentes na parede celular das forragens. -/- -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- -/- BEN ASHER, Aharon.

Uno dei principali problemi nello studio della mente e della sua "collocazione" consiste nell'identificazione del corretto Livello di Astrazione a cui le varie descrizioni fenomeniche e le corrispondenti ipotesi esplicative possono essere sviluppate e confrontate. L'articolo contribuisce all'attuale dibattito metodologico in filosofia della mente analizzando due nozioni fondative, quella di modello e quella di simulazione, sulla base del concetto di Livello di Astrazione. L'ambito è quello del Metodo delle Astrazioni, proposto in Floridi e Sanders [2003]. Il Metodo delle Astrazioni si (...) basa su una particolare branca dell'informatica teorica, quella dei Metodi Formali (Roever e Engelhardt [1998]; Woodcock e Davies [1996]), dove la matematica discreta è utilizzata per descrivere analiticamente le specifiche del comportamento di sistemi che elaborano informazioni. I sistemi sono descritti in termini di osservabili e regole di transizione, cioè come sistemi di transizione. Le descrizioni comportano l'utilizzo di variabili che rappresentano osservabili nella realtà, astraendo da altri eventuali osservabili. L'idea di fondo del Metodo delle Astrazioni è che tale processo di filtraggio sia ineliminabile in qualsiasi accesso alla realtà. Il tentativo di sondare un sistema in maggiore profondità produce una maggiore astrazione delle teorie e degli oggetti teorici che descrivono tale sistema. Il Metodo delle Astrazioni si presenta quindi come uno strumento per organizzare e chiarificare le varie teorie che intendono fornire una spiegazione della realtà o della conoscenza. La principale tesi dell'articolo è che "modello" e "simulazione" non possano essere pensati come nozioni a sé stanti, ma che la loro natura possa essere chiarita nei termini di tipi di relazioni tra sistemi di transizione. Nello specifico, si argomenta che la relazione di simulazione è una relazione tra gli osservabili di sistemi di transizione, mentre il modello è una relazione tra le regole di transizione di questi sistemi. Dati questi due nuovi tipi di relazioni, è possibile arricchire con ulteriori strutture di analisi il Metodo delle Astrazioni, estendendo la sua applicabilità. Queste strutture sono discusse nell'articolo come "Reti di Astrazione". (shrink)

In this chapter, we turn our attention to the effects of the attention economy on our ability to act autonomously as a group. We begin by clarifying which sorts of groups we are concerned with, which are structured groups (groups sufficiently organized that it makes sense to attribute agency to the group itself). Drawing on recent work by Purves and Davis (2022), we describe the essential roles of trust (i.e., depending on groups to fulfill their commitments) and trustworthiness (i.e., (...) the property of a group that makes trusting them fitting) in autonomous group action, with particular emphasis on democratic institutions (which we view as group agents) and democratic legitimacy (which depends on trust and trustworthiness). We then explain how engagement maximization promotes polarization, which is detrimental to trust and trustworthiness and, in turn, democratic legitimacy and democratic institutions. We close by considering what groups might do to protect themselves from the threat posed to them by the attention economy. (shrink)

Financial gerontology can be defined as investigating relations between finances and aging. Authors such as Neal E. Cutler, Kouhei Komamura, Davis W. Gregg, Shinya Kajitani, Kei Sakata, and Colin McKenzie affirm that financial literacy is an effect of aging with concern about the issue of finances, as well as stating that it is the effect of longevity and aging on economies or the financial resilience of older people.

One of the controversial issues in the development of Heidegger’s thought is the problem of the will. Th e communis opinio is that Heidegger embraced the concept of the will in a non-critical manner at the beginning of the thirties and , in particular, he employed it in his political speeches of 1933–1934. Jacques Derrida for instance speaks about a “massive voluntarism” in relation to Heidegger’s thought in this period. Also Brett Davis discerns a period of “existential voluntarism” in (...) 1930–1934, in which Heidegger takes over a notion of the will in a non-critical manner. In this article, this interpretation is challenged and a stronger interpretation of Heidegger’s concern with the will is developed. Our hypothesis is that Heidegger’s concern with the will at the onset of the thirties is brought about by his confrontation (Auseinandersetzung) with the concept of the will. Based on his lecture courses from 1930 and 1936/37 and his Rectoral Address from 1933, enables us to discern three main characteristics of Heidegger’s destructed concept of the will in the early thirties.

I show that unlike her rationalist predecessor Leibniz, Du Châtelet is committed to epistemic causal idealism about natural causes. According to this view, it is constitutive of natural causes that they are in principle knowable by us (i.e., finite intelligent beings). Du Châtelet’s causal idealism stems at least in part from the distinctive theoretical role played by the Principle of Sufficient Reason in her system (as presented in her _Institutions de physique_), as well as her argument for the Principle of (...) Sufficient Reason. I show that far from merely explicating Leibniz’s metaphysics, Du Châtelet develops a radical and novel rationalism that is in keeping with her core commitment to science. (shrink)

Leibniz endorses the world apart doctrine, according to which a substance is that which is independent of all other things except God. However, I will argue that in what appears to be a radical departure from the causal version of the world apart doctrine, Du Châtelet—whose metaphysics appears to be Leibnizian from a distance—embraces the causal connectedness of created substances. I further show that Du Châtelet’s rejection of Leibniz’s claim that a substance is causally independent of all other created substances (...) can be traced back to a more fundamental antiLeibnizian commitment on Du Châtelet’s part concerning the in-principle accessibility of natural (i.e., non-divine) sufficient reasons by finite minds and to her commitment to a causal theory of intentionality.

With An Answer to the Question: What Is Enlightenment? (1784) and What Does It Mean to Orient Oneself in Thinking? (1786), Kant presents the concept of public use of reason and defines its requirements, scope, and function. In outline, the public use of reason consists in sharing one’s thoughts with “the entire public of the world of readers” (8:37). As for its requirements, to the extent that someone communicates in their own person, i.e. not in the exercise of their function (...) as a public official, and bases their reasoning on universalizable grounds, their use of reason qualifies as public and shall be free from state censorship. Therefore, Kant’s concept of public use reason aims to establish a public debate that is free and includes in its scope, both as subjects and recipients, potentially all adult men. The ultimate function of the public use of reason is to foster moral progress and, with it, the reform of the political community according to the republican ideal. However, it is commonly held that Kant, with his 1798 essay The Conflict of the Faculties, deprives his notion of public use of reason of its progressive core and adjusts it to the absolutist conception of speech and civil service. Characterizations of state officials as “not free to make public use of their learning” (7:18) and “bound to uphold whatever […] the crown sanctions for them to expound publicly” (7:8), as well as the depiction of laypeople as “incompetent” (7:18) and “resigned to understanding nothing about [the sciences]” (7:34), have led influential interpreters to read Kant as redefining his notion of public use of reason by restricting its subjects to university professors and its recipients to government members (e.g. John Christian Laursen 1986, rpt. 1992 and 1996; Kevin Davis 1992; Steven Lestition 1993; Jay Franzel 2013). On my reading, with The Conflict of the Faculties, Kant does indeed redefine the concept of public use of reason making concessions to the absolutist notion of speech and civil service. However, a close reading of the text reveals that the public use of reason ends up being reaffirmed in its progressive core and extended in its scope. To substantiate my interpretation, I will systematically analyse and classify each of the 68 occurrences of the adjective ‘public’ in The Conflict of the Faculties and show how Kant employs the absolutist vocabulary to convey the progressive project of his previous writings. Accordingly, I argue that Kant holds on to the free public use of reason as a means to reform politics according to the republican ideal and that the employment of the absolutist vocabulary is motivated by a pragmatic attitude and a provocative stance.

Financial gerontology can be defined as investigating relations between finances and aging. Authors such as Neal E. Cutler, Kouhei Komamura, Davis W.

Nelson Goodman notoriously distinguished between autographic works, whose instances should be identified by taking history of production into account, and allographic works, whose instances can be identified independently of history of production. Scholars such as Jerrold Levinson, Flint Schier, and Gregory Currie have criticized Goodman’s autographic/allographic distinction arguing that all works are such that their instances should be identified by taking history of production into account. I will address this objection by exploiting David Davies’ distinction between e-instances and p-instances of (...) a work, thereby restating the autographic/allographic distinction. Then, I will show that this way of restating this distinction leads us to effective accounts of relevant related phenomena such as forgery, plagiarism, and digital technologies. Finally, I will show the theoretical advantages of my account of the autographic/allographic distinction in comparison with an alternative account recently proposed by Jason D’Cruz and P.D. Magnus.

Several recent studies in many different fields have focused on the question of how music can be expressive of such emotions that only sentient beings can feel. In philosophy of music the adherents of cognitivist theories of expressivity (e.g. Davies 2003, Kivy 2002) try to solve this problem by explaining that we hear music as expressive of emotions, because we hear the events and contours of music as resembling the typical ways in which human beings express their emotions in behaviour (...) and utterance. In cognitivist theories listeners are not supposed to have any reactionary feelings to the expressed emotions, whereas ‘arousalists’ (e.g. Matravers 1998) emphasize that a listener’s experience of expression involves an aroused feeling that is related to the expressed emotion; this aroused feeling makes it the case that we describe music as melancholic, for instance. The third type of philosophical theory of expressivity is the symbolist account (Addis 1999, Langer 1951) whose defenders regard music as isomorphic with our feelings and states of consciousness; in particular, special stress is laid on the idea that music is capable of presenting these ineffable states.

This article discusses the relationship (or lack thereof) between authors’ intentions and the meaning of literary works. It considers the advantages and disadvantages of Extreme and Modest Actual Intentionalism, Conventionalism, and two versions of Hypothetical Intentionalism, and discusses the role that one’s theoretical commitments about the robustness of linguistic conventions and the publicity of literary works should play in determining which view one accepts.

At the heart of Anders Pettersson’s 2017 book, The Idea of a Text and the Nature of Textual Meaning, is his proposed “cluster” definition of a textual work. On this view, a text is a cluster of three kinds of objects: all the physical exemplars of the work, the work’s meaning, and the complex signs that convey that meaning. Pettersson contrasts this with the “ordinary conception” of a text, wherein a text is a unitary object made of the signs and (...) meaning, and each exemplar is an instance of the supervening textual work. The cluster definition is preferable because it is able to overcome contradictions plaguing the ordinary conception and its competitors. This cluster conception of a textual work is both original and deserving of more critical attention. Pettersson not only motivates the view well through his consideration of key examples, but deftly handles the obvious objections. Although the cluster conception is revisionary of our ordinary conception, he makes a strong case. However, I do not focus here on the heart of Pettersson’s work but on something akin to its spleen; Pettersson’s criticism of David Davies’ “Pragmatic Constraint” (PC) on the ontology of artworks.

Simple idealized models seem to provide more understanding than opaque, complex, and hyper-realistic models. However, an increasing number of scientists are going in the opposite direction by utilizing opaque machine learning models to make predictions and draw inferences, suggesting that scientists are opting for models that have less potential for understanding. Are scientists trading understanding for some other epistemic or pragmatic good when they choose a machine learning model? Or are the assumptions behind why minimal models provide understanding misguided? In (...) this paper, using the case of deep neural networks, I argue that it is not the complexity or black box nature of a model that limits how much understanding the model provides. Instead, it is a lack of scientific and empirical evidence supporting the link that connects a model to the target phenomenon that primarily prohibits understanding. (shrink)

There is an undeniable tendency to dismiss women’s sexual assault allegations out of hand. However, this tendency is not monolithic—allegations that black men have raped white women are often met with deadly seriousness. I argue that contemporary rape culture is characterized by the interplay between rape myths that minimize rape, and myths that catastrophize rape. Together, these two sets of rape myths distort the epistemic resources that people use when assessing rape allegations. These distortions result in the unjust exoneration of (...) people we cannot conceive of as monstrous, while making it too easy to believe that some marginalized people could be rapists. I also argue that rape myths enable a novel kind of epistemic injustice. This injustice concerns how our assessments of trustworthiness and our assessments of plausibility interact. I argue that rape myths can result in runaway credibility deflations that can explain both why people fail to believe most women, and also why people may unjustly believe false allegations that white women have been raped by black men.

Standpoint theorists have long been clear that marginalization does not make better understanding a given. They have been less clear, though, that social dominance does not make ignorance a given. Indeed, many standpoint theorists have implicitly committed themselves to what I call the strong epistemic disadvantage thesis. According to this thesis, there are strong, substantive limits on what the socially dominant can know about oppression that they do not personally experience. I argue that this thesis is not just implausible but (...) politically pernicious; it is an excuse for ignorance and silence that stifles our ability to address many injustices. Moreover, I argue that if we are to avoid lending support to the SEDT while working within a standpoint theory framework, we must hold that the socially dominant can achieve marginalized standpoints. So, we must hold that men can achieve feminist standpoints, that white women (and men) can achieve black feminist standpoints, and so on. (shrink)

We argued in a recent issue of this journal that if abortion is restricted,1 then there are parallel obligations for parents to donate body parts to their children. The strength of this obligation to donate is proportional to the strength of the abortion restrictions. If abortion is never permissible, then a parent must always donate any organ if they are a match. If abortion is sometimes permissible and sometimes not, then organ donation is sometimes obligatory and sometimes not.
