A striking feature of the solar cycle is that at the beginning, sunspots appear around mid-latitudes, and over time the latitudes of emergences migrate towards the equator. The maximum level of activity varies from cycle to cycle. For strong cycles, the activity begins early and at higher latitudes with wider sunspot distributions than for weak cycles. The activity and the width of sunspot belts increase rapidly and begin to decline when the belts are still at high latitudes. However, in the late stages of the cycles, the level of activity, and properties of the butterfly wings all have the same statistical properties independent of the peak strength of the cycles. We have modelled these features using Babcock–Leighton type dynamo model and shown that the toroidal flux loss from the solar interior due to magnetic buoyancy is an essential nonlinearity that leads to all the cycles decline in the same way.

Crises, defined as a period of acute stress on social systems of all kinds, are a recurrent feature of history. As such, they are best approached and understood from a comparative historical perspective. We can distinguish between those caused or precipitated by an exogenous shock and those that derive from an endogenous process that culminates in the crisis. Crises can be of short or long duration and range from local to global. The most severe are ones that lead to a civilizational collapse or radical simplification process. Historically, severe crises have been localized to specific parts of the planet, even when several occur simultaneously because of global natural phenomena, but in the modern world we have truly global crises. Evidence suggests that such a global crisis is imminent or has already commenced. This raises practical and normative pressing issues.

This article reads Filipino director Lino Brocka's film Orapronobis (1989) as a commentary on the 1987 Philippine Constitution, a post-dictatorship document which the director helped draft as a member of the Philippine Constitutional Commission. Using a ‘law and film’ approach, the article argues that the film visualises law's limit concepts such as the state of exception, hostis generis humani, and constituent power. The film depicts the failure of words to control the political world that results in a dystopian constitutional order where human rights monsters and revolutionaries contend. Through an exploration of law's limit concepts, Brocka's Orapronobis represents the limits of Philippine constitutionalism.

Suppose that state A attacks state D without warrant. The ensuing military conflict threatens international peace and security. State D (I assume) has a justification for defending itself by means of military force. Do third parties have a justification for intervening in that conflict by such means? To international public lawyers, the well-rehearsed and obvious answer is “yes.” Threats to international peace and security provide one of two exceptions to the legal and moral prohibition (as set out in Article 2[4] of the UN Charter) on using force as a means for resolving interstate disputes. Just war theorists are not as verdictive. Compared to the ethics of humanitarian intervention and the ethics of national self-defense, the ethics of third-party military involvement in interstate conflicts remains underdeveloped in contemporary just war theory. This essay begins to fill that gap. I argue that to defend such interventions is tantamount to defending preventive military force, deterrent military force, and the resort to force in more cases than standardly thought. I then provide an account and limited defense of the deterrence argument. I show that deterrence is morally justified in relatively few cases and examine two problems with the argument: deterrence failures and the level of uncertainty under which leaders who use deterrent force operate. I conclude that we should take seriously the possibility that nonintervention, construed as the rejection of the direct use of military force, is the morally correct response to the most serious threats to international peace and security.

Khirbet Al-Sheikh Humaid is found 615 m above sea level in the central highlands of Palestine, northwest of the city of Nablus. During rescue excavations carried out at the site, part of a male human skull with a tooth attached was discovered. Accelerator mass spectrometry radiocarbon (AMS 14C) dating and stable isotope analysis were performed on the tooth at the Hertelendi Laboratory in Debrecen, Hungary. Dating revealed the individual had lived in the time frame 900–1030 AD, which is within the Abbasid period (750–1258 AD). Dietary analysis gave information on the daily life of the inhabitants of the settlement, showing local agriculture provided a diet of legumes and vegetables.

This article proposes that Horace's Epodes and Ovid's Metamorphoses open with significant acrostics that comprise the first two letters, in some cases forming syllables, of successive lines: IB-AM/IAMB (Epod. 1.1–2) and IN-CO-(H)AS (Met. 1.1–3). Each acrostic, it will be argued, tees up programmatic concerns vital to the work it opens: generic identity and the interrelation of form and content (Epodes), etymology and monumentality (Metamorphoses). Moreover, as befits their placement at the head of collections, both acrostics negotiate the challenge of literary commencement. The introduction reviews recent developments in acrostic studies and discusses important predecessors and parallels for Horace's and Ovid's ‘two-letter’ and syllabic acrostics. Two subsequent sections examine the acrostics singly, and a conclusion compares the dialogues that these acrostics open between author and reader, underscoring the welcome challenge which Ovid's acrostic offers to the prevailing scholarly view that this form of wordplay is a strictly visual affair.

This article by Ian Hunter, which has been adapted from his BIALL Conference presentation at the Belfast Europa Hotel, examines increasing the visibility of law firm library and information services in terms of what should be done and what should not be done. Or, as Ian puts it: “Is saying yes to everything really the right thing to do?”

This Note explores an alarming, decades-old trend that has received renewed attention from enforcement agencies and the media: nursing homes suing family members and friends ("relatives") for residents’ unpaid bills. As justification, nursing homes point to “responsible party” clauses within admission agreements signed by relatives during the admission process. Undeterred by the 1987 Federal Nursing Home Reform Act’s (FNHRA) prohibition on requiring relatives to act as financial guarantors in exchange for residents’ admission, nursing homes use carefully worded “responsible party” clauses to obtain virtually the same result: relatives’ total liability for residents’ unpaid balances. Relatives are frequently caught off-guard by these lawsuits; many who sign admission agreements do so without a proper understanding of the potential liability they are assuming and have limited (if any) access to residents’ assets. This problem is aggravated by several aspects of the admission process that disadvantage relatives, such as the stressful and emotional nature of admission, the complicated language in admission agreements, and the inadequate—at times, misleading—guidance provided by nursing homes. This Note examines the tension between the FNHRA’s financial protections for relatives and nursing homes’ admission practices and use of “responsible party” clauses. Furthermore, this Note proposes solutions aimed at better informing relatives of the legal risks associated with “responsible party” clauses.
