This study aimed to evaluate the effect of marine-based rumen buffer (Lithothamnium calcareum) supplementation on rumen health as well as milk yield and composition and also behavioural and metabolic parameters of dairy cows. Thirty-six lactating multiparous Holstein cows were used with a milk yield average of 39 kg/d and 64 d in milk. The experiment was conducted over 60 d using two groups: control (CON; n = 18) was supplemented with sodium bicarbonate at 1.1% dry matter and a treatment group that received Lithothamnium calcareum at 0.5% of dry matter (LITHO; n = 18). Each group was fed daily with the buffers mixed to the total mixed ration containing 29.28% starch. Ruminal fluid collections were performed weekly to evaluate pH and volatile fatty acids. Feeding behaviour data were obtained through automatic feeders, while overall behavioural data were obtained using monitoring collars. Milk yield was recorded daily and adjusted for fat and energy. Milk samples were retrieved once weekly for analysis of fat, protein, lactose and total solids. Blood samples were collected weekly for metabolic analysis and faecal samples were collected weekly to evaluate pH and starch concentrations. LITHO produced more fat- and energy-corrected milk (P ≤ 0.01) as well as the highest percentage of fat and solids (P < 0.05) when compared to the CON group. Data on feeding behaviour showed an increased eating time (P ≤ 0.01) in the LITHO group but a higher eating rate (P < 0.01) in the CON group. Animals from the LITHO group had lower faecal pH (P < 0.05). The treatment did not affect dry matter intake, animal behaviour, ruminal acid–base balance, or faecal starch. In summary, Lithothamnium calcareum supplementation at 0.5% of dry matter improved milk yield, milk composition and, presumably, feed conversion efficiency.

Recent authorities emphasize the longstanding inclusion of the Isle of Man in the territorial extent of English/British parliamentary legislation. This aligns with views of the territorial ambition of ministers of the crown and members of parliament in their operation of parliament's role in receipt of petitions and especially in the shaping of legislation. While contemporary authorities on Channel Island law, especially those in the islands themselves, are more cautious about the territorial extent of such legislation, it remains, at least by implication, the norm to assert that all of these territories, now Crown Dependencies, could be included by express provision in English/British statute law, and that there might be strong assumptions of inclusion even when they were not expressly named. The evidence for the period before 1640 does not tend to support these arguments. Instead, the Anglo-centric instincts of the English parliament from the mid-fourteenth century to the 1530s are clear. And even in the 1530s and 1540s, in legislation spurred by jurisdictional and administrative imperatives in ecclesiastical matters, as a result of the Break with Rome, there was only tentative and limited change to the territorial extent of English law.

The Occupation of Japan (1945-1952) sought to democratize the nation’s education system; pupil guidance was expected to play a key part of this process. American reformers promoted new guidance practices (e.g., the comprehensive collection of students’ personal data, guidance interventions based on the case-study method, an expanded homeroom curriculum) that emphasized the psychological adjustment—translated as tekio (適応)—of students to school and society in a new Japan. By tracing the evolution of prewar and postwar Japanese guidance discourse, this study examines how American pupil guidance’s emphasis on student adjustment interacted with, and transformed, twentieth-century Japanese education. Drawing from prewar, Occupation-era and post-independence sources, the essay explores three points. First, by comparing prewar life guidance with Occupation-era and post-independence pupil guidance, it emphasizes the important changes effected by tekio-oriented guidance during the late 1940s. Second, by examining the way these practices related to Occupation’s educational democratization, it explores how their psychological approach to democracy defined—and arguably constrained—the dynamism of this broader project. Lastly, the work discusses who supported and opposed this new tekio discourse. American authorities succeeded in garnering the support of many elites in Japanese education (e.g., Ministry of Education officials, leading academics), but other educators remained skeptical.

We study the counts of smooth permutations and smooth polynomials over finite fields. For both counts we prove an estimate with an error term that matches the error term found in the integer setting by de Bruijn more than 70 years ago. The main term is the usual Dickman $\rho$ function, but with its argument shifted.

We determine the order of magnitude of $\log(p_{n,m}/\rho(n/m))$ where $p_{n,m}$ is the probability that a permutation on n elements, chosen uniformly at random, is m-smooth.

We uncover a phase transition in the polynomial setting: the probability that a polynomial of degree n in $\mathbb{F}_q$ is m-smooth changes its behaviour at $m\approx (3/2)\log_q n$.

We evaluated the effect of including 0, 2, 5, 10, 20, 40 and 100% of individual milk from cows at extended lactation (more than 315 d in milk) on milk ethanol stability (MES), pH, acidity and ionic calcium (iCa) of the bulk tank milk. The study was carried out on commercial dairy farms in Brazil using milk samples of individual cows, bulk tank and their mixtures. Samples of individual cows were classified as low (≤74%), intermediate (76–78%) and high (≥80%) stability classes based on MES. Data were submitted to Anova, multiple linear regression analysis and logistic regression. Low, intermediate and high stability milk had values of 108, 89 and 79 mg/dl for iCa, and 21, 23 and 20 for acidity, respectively, but similar values for pH and DIM. MES increased linearly with pH, while it decreased linearly with iCa. When individual milks presented higher MES than bulk tank milk, MES and pH increased linearly with individual milk inclusion and DIM, while iCa decreased with individual milk inclusion. When individual milks presented lower MES than bulk tank milk, MES decreased, while iCa increased linearly with individual milk inclusion. Inclusion of milk with higher MES than the bulk tank decreased the odds of low stability, while inclusion of individual milk with lower MES than bulk tank increased it. At extended lactation, 73% of cows produced milk with acceptable (intermediate or better) MES, and iCa was the only functional variable related to MES. Effects of the mixture of individual milks into bulk tank milk functional traits depend on whether individual cows present values higher or lower than bulk tank.

The study of the Western Indian Ocean in the first millennium is a dynamic and exciting field, in which scholarship, especially from within the Indian Ocean region itself, is expanding rapidly. It is experiencing a period of major, but not necessarily disruptive, change, to its core questions, terminology and periodisation. This article offers an overview of the study of Roman trade with the Western Indian Ocean (sometimes termed ‘Indo-Roman studies’) from the early 2000s to the present. It examines key developments in the field, including the changing scope of analysis in terms of period, region and evidence; the impact in the field of an increasingly global focus and efforts to decolonise a subject historically deeply rooted in colonial processes; and specifically the effort to provincialise or decentre Rome in historical narratives. It then suggests directions in which the field appears to be developing and makes tentative suggestions for future work.

Washington, DC was littered with fliers that promoted shows happening within the local punk scene during the 1980s. Often posted on poles, walls, and bulletin boards around the city, these fliers included which bands were playing, the date of the show, entry cost, and the name and location of the performance space. For shows that occurred in the homes, community centers, and schools of suburban Maryland and Virginia, the flier maker often included an address as well as directions. Sometimes these directions took the form of a hand-drawn map. More often, they were written in prose.

This article studies the directions included on such fliers and asks, “where do flier makers assume attendees will begin their travels?” To answer this question, it adopts a methodology from geographic information systems (GIS) and follows the directions backwards from the venue to the unspoken and assumed starting point. Such methods show how directions typically began in the suburbs themselves or in and around Georgetown, one of DC's more affluent neighborhoods.

The individuals that made these fliers functioned as popular cartographers who, via their directions or maps, articulated their identity and worldview. By focusing on the unassumed, unspoken, and default “starting point” of punk audiences, this article argues that punk fliers created a view of DC that articulated and engrained a segregationist, classist, exclusionary logic, even within a progressive, integrated musical scene that existed in the city during the 1980s.

Digital-era music videos are a crucial part of singers’ mediatic performances. Lip-synching is often central to such products, supplying situations in which singers can mouth their voices while dislodging themselves from the struggles of singing. Looking into music videos by focusing on their lip-synching practices, this paper aims to understand the part voice takes on in the medium while also investigating how gestural lip-sync performances work as accounts of oneself that produce a musical subject, sometimes updating or overcoming social regulations. In this sense, lip-synching is theorized as a way of framing music videos’ gestural labour.

I’m sat at my office desk writing this review when I receive a notification on my phone. An alert of this kind would usually be unworthy of comment. Yet, this notification informs me of a recent BBC News article on sperm whale vocalization. Intrigued, I read the story, which explains how a team of Cetacean Translation Initiative (Ceti) researchers, led by PhD student Pratyusha Sharma at MIT, are using AI technology to analyse large bioacoustics datasets of sperm whale clicks. Their analysis shows that the combining of clicks in sperm whale communication appears to parallel the grouping of phonemes to create words in human languages. What the whales’ different rhythmic sequences of clicks — called ‘codas’ — mean, however, is still unknown. Scientists have, so far, only caught a glimpse of the lives of sperm whales, and so it is impossible to know at this stage what information is carried by particular combinations of codas.1
