Notes on family-group names for bees (Hymenoptera: Apoidea)
No full textAbstract. Corrected authorships and dates are provided for four family-group names for bees based on previously unrecognized earlier usages that made them nomenclatorially available. Sagemehl is newly recognized as the author of family-group names based on Dasypoda Latreille (Melittidae: Dasypodainae), Macropis Panzer (Melittidae: Macropidinae), and Hylaeus Fabricius (Colletidae: Hylaeinae), and Kawall as the author the family-group name based on Melitta Kirby, thereby taking precedence over the subsequent use of similar names by Börner, Robertson, Vi-ereck, and Schenck, respectively. In addition, descriptions are provided for three new family-group taxa; Dieunomiini Engel, new tribe (Halictidae: Nomiinae), Eremaphantina Engel, new subtribe (Melittidae: Hesperapini), and Tarsaliini Engel, new tribe (Apidae: Apinae); and one new genus-group taxon, Eremaphantella Engel, new subgenus

Clinonana rafaeli Engel et Takiya, sp. nov.
No full textClinonana rafaeli Engel et Takiya sp. nov. (Figs. 1 D, 6) Measurements in mm (ɗ holotype). Total length: 16.0. Crown median length: 1.1. Pronotum median length: 2.5. Pronotum largest width: 7.2. Mesonotum largest width: 4.0. Mesonotum median length: 4.3. External morphology. Crown (Figs. 1 D, 6 A) median length three-tenths of interocular (ratio= 0.34) and transocular width (ratio= 0.26). Pronotum (Figs. 1 D, 6 A) largest width 2.9 times median length; largest width 1.8 times largest mesonotum visible width. Mesonotum (Figs. 1 D, 6 A) length 1.2 times longer than combined mesal length of crown and pronotum. Other characteristics as in generic description. Male genitalia. Styles (Figs. 6 D, E) in lateral view with median concavity on ventral margin. Aedeagus (Figs. 6 G, H) shaft preatrium pair of processes extending only until two-thirds of shaft length. Female unknown. Notes. Clinonana rafaeli sp. nov. is very similar to C. mirabilis in external morphology and male genitalia. Both species are smaller and have a less laterally expanded pronotum (Figs. 1 C, D, 4 A, 6 A) than C. impensa (Figs. 1 B, 3 A). The new species differs from C. mirabilis by the following male genital characters: style in lateral view with ventral concavity in median portion (Fig. 6 E, arrow); and aedeagal shaft thinner than in C. mirabilis, with preatrium basal processes extending only two-thirds length of shaft (Figs. 6 G, H). In C. mirabilis the basal processes reach the apex of the aedeagus shaft. Etymology. The new species epithet is in honor of the dipterist Dr. José Albertino Rafael (INPA), who coordinated projects including field work in the Brazilian Amazon which made possible the collection of specimens of Clinonana and many other leafhoppers by the junior author, besides being responsible for the collection of about half of specimens studied herein.

Holding the line: The sustainability of police involvement in crime prevention
No full textThe opening lines of the handbook issued by Sir Robert Peel to all officers of the Metropolitan Police in 1829, were these:
‘It should be understood at the outset that the object to be attained is the prevention of crime. To this great end every effort of the police is to be directed. The security of person and property, the preservation of the public tranquility, and all the other objects of a police establishment will thus be better effected than by the detection and punishment of the offender after he has succeeded in committing the crime.’ Quoted in Reith (1948:62). Mayne, one of the first two Commissioners, added this principle: ‘To prevent crime and disorder, as an alternative to their repression by military force and severity of legal punishment.’ Quoted in Boyd (2012). What exactly they meant by prevention is open to interpretation, and whether this was just a ruse to help convince a suspicious public that in England ‘continental’ methods of repression would not be adopted is not clear. But by the late 19th Century the reactive approach of catching criminals or ‘feeling collars’ had come to predominate; and in the 20th, the politically-significant rhetoric of ‘fighting crime’ achieved consensual hegemony, delivered huge resources to policing over the years and of course powerfully shaped the policing organisation. It was not until the 1960s that the first signs of resurgence of an explicit, practical, preventive role were seen
Institutions for Intuitive Man
No full textBy its critics, the rational choice model is routinely accused of being unrealistic. One key objection has it that, for all nontrivial problems, calculating the best response is cognitively way too taxing, given the severe cognitive limitations of the human mind. If one confines the analysis to consciously controlled decision-making, this criticism is certainly warranted. But it ignores a second mental apparatus. Unlike conscious deliberation, this apparatus does not work serially but in parallel. It handles huge amounts of information in almost no time. It only is not consciously accessible. Only the end result is propelled back to consciousness as an intuition. It is too early to decide whether the rational choice model is ultimately even descriptively correct. But at any rate institutional analysts and institutional designers are well advised to take this powerful mechanisms seriously. In appropriate contexts, institutions should see to it that decision-makers trust their intuitions. This frequently creates a dilemma. For better performance is often not the only goal pursued by institutional intervention. Accountability, predictability and regulability are also desired. Sometimes, clever interventions are able to get them both. Arguably, the obligation to write an explicit set of reasons for a court decision is a case in point. The judge is not obliged to report the mental processes by which she has taken her decision. Justification is only ex post control. Intuitive decision-making is even more desirable if the underlying social problem is excessively complex (NP hard, to be specific), or ill-defined. Sometimes, it is enough for society to give room for intuitive decision-making. For instance, in simple social dilemmas, a combination of cheater detection and punishing sentiments does the trick. However, intuition can be misled. For instance, punishing sentiments are triggered by a hurt sense of fairness. Now in more complex social dilemmas, there are competing fairness norms, and people intuitively choose with a self-serving bias. In such contexts, institutions must step in so that clashing intuitions do not lead to social unrest.intuition, consciousness, rational choice, heuristics, ill-defined social problems, institutions
Family-group names for bees (Anthophila)
No full text33 p. ; 26 cm.Includes bibliographical references (p. 17-27).The 173 family-group names for bees (Apoidea: Anthophila) are cataloged in chronological order. For each name the correct author, date, type genus, and combining stem are provided. The following names are considered nomina nuda: Phenacolletini, Ctenioschelini, Chalicodomopsini, Liphanthini, Austropanurgini, and Hoplitini. The authorship of three names (Tapinotaspidini, Hexepeolini, and Ancyloscelidina) is corrected as each was a nomen nudum when first proposed, but has been subsequently made available by other authors. The following new names are proposed herein: Scraptrinae Ascher and Engel, new subfamily (Colletidae); Neffapini Ascher, new tribe (Andrenidae: Panurginae); Afrodasypodini Engel, new tribe (Melittidae: Dasypodainae), Afrodasypoda Engel, new genus; Hesperapina Ascher and Engel, new subtribe (Melittidae: Dasypodainae); Macrogaleina Engel, new subtribe (Apidae: Xylocopinae); and Ancyloscelidina Engel and Michener, new subtribe (Apidae: Apinae). A hierarchical outline of Apoidea classification (inclusive of the digger wasps), indicating the suggested current usage of all available family-group names is appended. The name Anthophila, as proposed by Latreille, is adopted for the bees as a whole

The Difficult Reception of Rigorous Descriptive Social Science in the Law
No full textMutual disdain is an effective border patrol at the demarcation lines between disciplines. Social scientists tend to react with disdain when they observe how their findings are routinely stripped of all the caveats, assumptions and careful limitations once they travel into law. Likewise, lawyers tend to react with disdain when they read all the laborious proofs and checks for what looks to them like a minuscule detail in a much larger picture. But mutual disdain comes at a high price. All cross-border intellectual trade is stifled. This paper explores the social science/law border from the legal side. The natural barriers turn out to be significant, but not insurmountable. Specifically the paper looks at the challenges of integrating rigorous descriptive social science into the application of the law in force by courts and administrative authorities. This is where the gap is most difficult to bridge. The main impediments are implicit value judgments inherent in models, conceptual languages and strictly controlled ways of generating empirical evidence; the difference between explanation, hypothesis testing and prediction, on the one hand, and decision-making, on the other; the ensuing difference between theoretical and practical reasoning, and the judicial tradition of engaging in holistic thinking; last but not least, the strife of the legal system for autonomy, in order to maintain its viability. If a legal academic assumes the position of an outside observer, she may entirely ignore all these concerns and simply follow the methodological standards of descriptive social science. This is, for instance, what most of law and economics does. The legal academic may, instead, choose to contribute to the making of new law. She will then find it advisable to partly ignore the strictures of rigorous methodology in order to be open to more aspects of the regulatory issue. But it is not difficult, at least, to follow the standards of the social sciences for analysing the core problem. The integration is most difficult if an academic does doctrinal work. But it is precisely here where the division of intellectual labour between legal practice and legal academia is most important. Academics who themselves are versatile in the respective social science translate the decisive insights into suggestions for a better reading of statutory provisions or case law.law and economics, law and statistics, explanation vs. decision-making, practical reasoning, psychology of judicial decision-making
