(BJ6.350)Those who discard their weapons and surrender their persons, I will let live. Like a lenient master in a household, I will punish the incorrigible but preserve the rest for myself.So ends Titus' address to the embattled defenders of Jerusalem in the sixth book of Josephus'Jewish War(6.328-50). It is the most substantial instance of communication between Romans and Jews in the work. Titus compares himself to the master of a household and the Jewish rebels to his slaves. Is this how we expect a Roman to describe empire? If not, what does it mean for our understanding of the politics of Josephus' history? The question is particularly acute given that this is not just any Roman but Titus himself: heir apparent and, if we believe Josephus, the man who read and approved this historical account. It is thus surprising that, while the speeches of Jewish advocates of submission to Rome such as Agrippa II (2.345-401) and Josephus himself (5.362-419) have long fascinated readers, Titus' speech has received little or no attention. Remarkably, it is not mentioned in any of three recent collections of essays on Josephus. This paper aims to highlight the rhetorical choices that Josephus has made in constructing this voice for Titus—particularly his self-presentation as master—and the interpretive questions these raise for his readers. It should go without saying that the relationship of this text to anything that Titus may have said during the siege is highly problematic. (Potentially more significant, but unfortunately no less speculative, is the question of how it might relate to any speech recorded in the commentaries of Vespasian and Titus that Josephus appears to have used as a source.) What we have is a Josephan composition that is embedded in the broader narrative of theJewish War.

ABSTRACTThe incidence of oestrus in 603 Hereford heifers with a mean age of 545 days (range 515 to 575) was related to live weight (range 130 to 376 kg). Observations were ranked in order of ascending live weight and the percentage of heifers showing oestrus was calculated for consecutive 10 kg increments in live weight from 130 to 380 kg. The percentage showing oestrus was subjected to the probit transformation (Y, probit units) and was then related to live weight (X, kg):It was predicted that 50% of the heifers showed oestrus at 231 ± 1 kg, and that 5% and 95% showed oestrus at 187 and 280 kg respectively.

AbstractA set of infinite binary sequences ${\cal C} \subseteq 2$ℕ is negligible if there is no partial probabilistic algorithm that produces an element of this set with positive probability. The study of negligibility is of particular interest in the context of ${\rm{\Pi }}_1^0 $ classes. In this paper, we introduce the notion of depth for ${\rm{\Pi }}_1^0 $ classes, which is a stronger form of negligibility. Whereas a negligible ${\rm{\Pi }}_1^0 $ class ${\cal C}$ has the property that one cannot probabilistically compute a member of ${\cal C}$ with positive probability, a deep ${\rm{\Pi }}_1^0 $ class ${\cal C}$ has the property that one cannot probabilistically compute an initial segment of a member of ${\cal C}$ with high probability. That is, the probability of computing a length n initial segment of a deep ${\rm{\Pi }}_1^0 $ class converges to 0 effectively in n.We prove a number of basic results about depth, negligibility, and a variant of negligibility that we call tt-negligibility. We provide a number of examples of deep ${\rm{\Pi }}_1^0 $ classes that occur naturally in computability theory and algorithmic randomness. We also study deep classes in the context of mass problems, examine the relationship between deep classes and certain lowness notions in algorithmic randomness, and establish a relationship between members of deep classes and the amount of mutual information with Chaitin’s Ω.

ABSTRACTThis article considers language variation within one “ethnic” group: Israelis of Middle Eastern origins. Earlier studies (Yaeger-Dror, 1988, 1991) found that singers from the dominant “koiné” -speaking social group (Blanc, 1968) use [r] in pop songs and [R] in casual interviews. This can be defined as a register distinction. On the other hand, singers from a MidEastern ethnolinguistic background, whose underlying dialect includes [r], use [R] even in songs. Given that singers whose vernacular consonant invetory does not even include [r], and who should find it easire to use it categorically, have such a difficult time maintaing [r] consistently (and appropriately) in the song register? One of the recorded variants for these singers “merges” the [r] and [R] into coarticulated [rR]. Why does this previously unattested sound arise, and what does it tell us about the linguistic and sociolinguistic situation? Data from various registers are analyzed in order to discover the answers to these questions. This analysis is concerned with the quantifiable evidence of systematic patterns in the use of these three pronunciations for [r] and uses this evidence to demonstrate that subconscious sociolinguistic pressures on members of the minority community influence them to assimilate to the dominant social group while still retaining ethnolinguistic proof of a narrower ethnic identity. For example, the use of [rR] is found to be correlated with a wish to affiliate with both an [R]-using group and an [r]-using group, showing that sociolinguistic techniques can reveal social psychological ethinc affiliation. Like Trudgill's (1986) discussions of dialects in contact, the present theoretical discussion takes advantage of proposals advanced by Giles, to explain why the data reveal both convergence (toward the dominant out-group) and divergence (toward the in-group) (Giles & Coupland, 1991). Sociolinguistic methods permit a quantitative analysis of the strength of these conflicting tendencies, both of which are subsumed under the technical term “accommodation.” Methods are proposed to determine if choice of the[R] or [rR] variant is conscious or not, and variable rule analysis reveals that for most of the singers the less cognitive salience, the greater the degree of convergence to the Koiné norm [R]. The linguistic factors that are correlated with the relative degree of salience can be used in future studies when the relationship between convergence toward another dialect or language and relative cognitive salience is also at issue.

ABSTRACTData from three comparative slaughter experiments involving a total of 73 ewes were used to study the influence of body fat content at the start of lactation (X1 kg) and of metabolizable energy intake (X2, MJ/day), on the rate of loss of body fat by lactating ewes over the first 6 weeks of lactation (Y, g/day). The relationship was described by the equation:Thus the rate of fat loss was greater for ewes with higher initial fat contents, but the differential became less as metabolizable energy intake increased. Since increases in body fatness depress food intake it was not possible to prevent loss of body fat during early lactation in fat ewes given high concentrate diets ad libitum. The likely response in milk yield to increase in body fatness at parturition is therefore strongly dependent on the relative levels of body fatness and metabolizable energy intake. The value of any improvement in condition of the ewe at parturition may be considerable when metabolizable energy intake during lactation is low but much less when it is expected to be high.

AbstractLet 0<α<1 andβ>1. We show that everyx∈[0,1] has an expansion of the formwherehi=hi(x)∈{0,α/β}, andpi=pi(x)∈{0,1}. We study the dynamical system underlying this expansion and give the density of the invariant measure that is equivalent to the Lebesgue measure. We prove that the system is weakly Bernoulli, and we give a version of the natural extension. For special values ofα, we give the relationship of this expansion with the greedyβ-expansion.

Let θ(ν) be a formula in the first-order language of arithmetic and letIn this note we study the relationship between the schemas I′ and I+.Our interest in I+ lies in the fact that it is ostensibly a more reasonable schema than I′. For, if we believe the hypothesis of I+(θ) then to verify θ(n) only requires at most 2log2(n) steps, whereas assuming the hypothesis of I′(θ) we require n steps to verify θ(n). In the physical world naturally occurring numbers n rarely exceed 10100. For such n applying 2log2(n) steps is quite feasible whereas applying n steps may well not be.Of course this is very much an anthropomorphic argument so we would expect that it would be most likely to be valid when we restrict our attention to relatively simple formulas θ. We shall show that when restricted to open formulas I+ does not imply I′ but that this fails for the classes Σn, Πn, n ≥ 0.We shall work in PA−, where PA− consists of Peano's Axioms less induction together with∀u, w(u + w = w + u ∧ u · w = w · u),∀u, w, t ((u + w) + t = u + (w + t) ∧ (u · w) · t = u · (w · t)),∀u, w, t(u · (w + t) = u · w + u · t),∀u, w(u ≤ w ↔ ∃t(u + t = w)),∀u, w(u ≤ w ∨ w ≤ u),∀u, w, t(u + w = u + t → w = t).The reasons for working with PA− rather than Peano's Axioms less induction is that our additional axioms, whilst intuitively reasonable, will not necessarily follow from some of the weaker forms of I+ which we shall be considering. Of course PA− still contains those Peano Axioms which define + andNotice that, trivially, PA− ⊦ I′(θ) → I+(θ) for any formula θ.

Abstract.Banach introduced the following two-person, perfect information, infinite game on the real numbers and asked the question: For which sets A ⊆ R is the game determined?Rules: The two players alternate moves starting with player I. Each move an is legal iff it is a real number and 0 < an, and for n > 1, an < an−1. The first player to make an illegal move loses. Otherwise all moves are legal and I wins iff exists and .We will look at this game and some variations of it, called Banach games. In each case we attempt to find the relationship between Banach determinacy and the determinacy of other well-known and much-studied games.

Maximum oxygen uptake (VO2max) is a “gold standard” in aerobic capacity assessment, playing a vital role in various fields. However, ratio scaling (VO2maxbw), the present method used to express relative VO2max, should be suspected due to its theoretical deficiencies. Therefore, the aim of the study was to revise the quantitative relationship between VO2max and body weight (bw). Dimensional analysis was utilized to deduce their theoretical relationship, while linear or nonlinear regression analysis based on four mathematical models (ratio scaling, linear function, simple allometric model and full allometric model) were utilized in statistics analysis to verify the theoretical relationship. Besides, to investigate the effect of ratio scaling on removing body weight, Pearson correlation coefficient was used to analyze the correlation between VO2maxbw and bw. All the relevant data were collected from published references. Dimensional analysis suggested VO2max be proportional to bw23. Statistics analysis displayed that four mathematical expressions were VO2max = 0.047bw (p<0.01, R2 = 0.68), VO2max = 0.036bw+0.71 (p<0.01, R2 = 0.76), VO2max = 0.10bw0.82 (p<0.01, R2 = 0.93) and VO2max = 0.23bw0.66–0.48 (p<0.01, R2 = 0.81) respectively. Pearson correlation coefficient showed a significant moderately negative relation between VO2maxbw and bw (r = -0.42, p<0.01), while there was no correlation between VO2maxbw0.82 and bw (r = 0.066, p = 0.41). Although statistics analysis did not fully verify the theoretical result, both dimensional and statistics analysis suggested ratio scaling distort the relationship and power function be more appropriate to describe the relationship. Additionally, we hypothesized that lean mass, rather than body weight, plays a more essential role in eliminating the gap between theoretical and experimental b values, and is more appropriate to standardize VO2max, future studies can focus more on it.
