Lawrence of Arabia’s War: The Arabs, the British and the Remaking of the Middle East in WWI

Seldom does a newly published book both enlarge our understanding of its subject and enhance our appreciation of its principal primary sources. In Lawrence of Arabia’s War, Neil Faulkner admirably achieves both objectives. In the first instance, he thoroughly and critically discusses British foreign policy and military operations in the Middle East and North Africa from 1914 through 1922, with emphasis upon British relations with the Arabs, primarily the desert-dwelling Hashemite sherifs as opposed to the landlords and officials who dominated millions of Arab small farmers and city dwellers. Whenever appropriate, he carefully examines relations between the British and their French, Italian, and Russian allies. In the second instance, Faulkner clearly illuminates the political and military context of T. E. Lawrence’s partially autobiographical Seven Pillars of Wisdom, long widely admired as one of the finest literary masterpieces of the Great War and as a somewhat impressionistic portrait of the leaders of the Arab rebellion. In doing so, Faulkner further demonstrates Lawrence’s memoir to be an informed evaluation of British strategy and of the actions of Arab and Bedouin chieftains in their relationships with the British and with one another. Furthermore, Faulkner shows how and why Seven Pillars of Wisdom is one of the few World War I memoirs that facilitate one’s comprehension of the military operations by which Arab forces during 1917 and 1918 interdicted Ottoman supply lines and effectively supported the right flank of British offensives into Gaza and Palestine

Early-Morning and Late-Night Maximal Runs: Metabolic and Perceived Exertion Outcomes

People may exercise at the ends of their day to fit activity into their schedule; the purpose of this investigation was to determine if metabolic or perceived exertion outcomes differed between maximal runs early in the morning and late at night. After consuming a standardized, glucose drink, thirteen recreationally active individuals completed an early-morning and a late-night run on the treadmill while researchers measured metabolic (aerobic capacity and substrate usage) and perceived exertion outcomes. Point of application #1: Aerobic capacity (maximal consumption of oxygen) and the usage of fat as a fuel to support energy production during exercise were similar between runs. Point of application #2: Maximal perceived exertion (Borg’s 6-20) was similar during early-morning and late-night runs. Point of application #3: While research indicates that people may prefer activity in the morning or evening, and this might impact metabolic responses to the exercise bout, most of our participants (n=8) identified with no preference for exercising in the early-morning or late-night.

New Discoveries from the Arecibo 327 MHz Drift Pulsar Survey Radio Transient Search

We present Clusterrank, a new algorithm for identifying dispersed astrophysical pulses. Such pulses are commonly detected from Galactic pulsars and rotating radio transients (RRATs), which are neutron stars with sporadic radio emission. More recently, isolated, highly dispersed pulses dubbed fast radio bursts (FRBs) have been identified as the potential signature of an extragalactic cataclysmic radio source distinct from pulsars and RRATs. Clusterrank helped us discover 14 pulsars and 8 RRATs in data from the Arecibo 327 MHz Drift Pulsar Survey (AO327). The new RRATs have DMs in the range $23.5 - 86.6$ pc cm$^{-3}$ and periods in the range $0.172 - 3.901$ s. The new pulsars have DMs in the range $23.6 - 133.3$ pc cm$^{-3}$ and periods in the range $1.249 - 5.012$ s, and include two nullers and a mode-switching object. We estimate an upper limit on the all-sky FRB rate of $10^5$ day$^{-1}$ for bursts with a width of 10 ms and flux density $\gtrsim 83$ mJy. The DMs of all new discoveries are consistent with a Galactic origin. In comparing statistics of the new RRATs with sources from the RRATalog, we find that both sets are drawn from the same period distribution. In contrast, we find that the period distribution of the new pulsars is different from the period distributions of canonical pulsars in the ATNF catalog or pulsars found in AO327 data by a periodicity search. This indicates that Clusterrank is a powerful complement to periodicity searches and uncovers a subset of the pulsar population that has so far been underrepresented in survey results and therefore in Galactic pulsar population models.Comment: 41 pages, 16 figures, 4 tables, accepted by ApJ; added minor corrections to final ApJ proo
