Geometric single‐qubit gates for an electron spin in a quantum dot
Authors: Malinovsky Vladimir S. , Rudin Sergey 
Published: June 2012

AbstractUsing the analytic expression of the evolution operator for the electron spin in a quantum dot, we propose a scheme to design a universal set of single‐qubit gates based solely on the geometric phase that the qubit state acquires after a cyclic evolution in the parameter space. The scheme is using ultrafast linearly chirped pulses providing adiabatic excitation of the qubit states and the geometric phase is fully controlled by the relative phase between pulses. © 2012 Wiley Periodicals, Inc.

Authors: Giribabu Lingamallu , Kanaparthi Ravi Kumar , Velkannan Veerapandian 
Published: June 2012

AbstractDye‐sensitized solar cells (DSSCs) have attracted considerable attention in recent years as they offer the possibility of low‐cost conversion of photovoltaic energy. This account focuses on recent advances in molecular design and technological aspects of sensitizers based on metal complexes, metal‐free organics and tetrapyrrolic compounds which include porphyrins, phthalocyanines as well as corroles. Special attention has been paid to the design principles of these dyes, and co‐sensitization, an emerging technique to extend the absorption range, is also discussed as a way to improve the performance of the device. This account also focuses on recent advances of efficient ruthenium sensitizers as well as other metal complexes and their applications in DSSCs. Recent developments in the area of metal‐free organic and tetrapyrrolic sensitizers are also discussed. DOI 10.1002/tcr.201100044
The Temporal Focus Scale: Factor structure and association with alcohol use in a sample of Northern Irish school children
Authors: McKay Michael T. , Percy Andrew , Goudie Andrew J. , Sumnall Harry R. , Cole Jon C. 
Published: June 2012

ABSTRACTThe Temporal Focus Scale (TFS) is a 12‐item self‐report measure of cognitive engagement with the temporal domains of past, present and future. Developed in college student samples, a three‐factor structure with adequate reliability and validity was documented in a series of independent studies. We tested the factor structure of the scale in a sample of Northern Irish adolescents and found that our data supported a three factor structure, although there were problems with item 10. Because time perspective measures have been found to relate differentially to various health behaviours, we tested the relations between scores on the TFS and self‐reported alcohol use. Results showed that scores on the TFS were not consistent statistical predictors of drinking category in a logistic regression. Results are discussed in terms of scale development, future scale use and the assessment of health‐compromising behaviours such as adolescent alcohol consumption.
Low susceptibility of non-target Lepidopteran maize pests to the Bt protein Cry1Ab
Authors: Pérez-Hedo M. , López C. , Albajes R. , Eizaguirre M. 
Published: June 2012

AbstractTransgenic Bt maize expressing the Cry1Ab toxin is poorly effective for suppressing populations of two non-target Lepidoptera,Mythimna unipunctaandHelicoverpa armigera. In order to determine the mechanisms that may be involved in this poor effectiveness, last instar larvae of the two Lepidoptera were fed with a diet containing lyophilized leaves with Bt vs non-Bt toxin for different periods; additionally, some larvae fed on Bt diet were transferred to non-Bt diet for an additional period. In the experimental larvae, we measured the growth (weight) gain from just before treatment to after the end of the treatment, and the Cry1Ab contents in the hemolymph, the peritrophic membrane and its contents and midgut epithelium. Effects of the treatments on the midgut epithelium were observed by light and transmission electron microscopy. It was seen that multiple mechanisms can be involved in the low susceptibility of the two Lepidoptera. The low content of the toxin within the peritrophic membrane 48h after ingestion indicates a high rate of toxin elimination in this space. Moreover,M. unipunctalarvae fed on the Bt diet displayed a similar growth gain index to those fed on the non-Bt diet, and showed an increasing elimination rate during the experiment. Little toxin reached the midgut epithelium, indicating a low permeability of the peritrophic membrane or a low affinity at the binding sites. Larvae fed on the Bt toxin showed rapid recovery in weight gain and in the midgut epithelium, and also showed overcompensation mechanisms.
Diversity and localization of bacterial symbionts in three whitefly species (Hemiptera: Aleyrodidae) from the east coast of the Adriatic Sea

Published: June 2012

AbstractSeveral whitefly species (Hemiptera: Aleyrodidae) are cosmopolitan phloem-feeders that cause serious damage in numerous agricultural crops. All whitefly species harbor a primary bacterial symbiont and a diverse array of secondary symbionts which may influence several aspects of the insect's biology. We surveyed infections by secondary symbionts in Bemisia tabaci (Gennadius), Trialeurodes vaporariorum (Westwood) and Siphoninus phillyreae (Haliday) from areas in the east cost of the Adriatic Sea. Both the Middle East-Asia Minor 1 (MEAM1) and Mediterranean (MED) B. tabaci genetic groups were detected in Montenegro, whereas only the MED was confirmed in Croatia. Trialeurodes vaporariorum and S. phillyreae were found in all areas surveyed. MEAM1 and MED exhibited similarity to previously reported infections, while populations of T. vaporariorum from Montenegro harbored Rickettsia, Wolbachia and Cardinium in addition to previously reported Hamiltonella and Arsenopnohus. Siphoninus phillyreae harbored Hamiltonella, Wolbachia, Cardinium and Arsenophonus, with the latter appearing in two alleles. Multiple infections of all symbionts were common in the three insect species tested, with some reaching near fixation. Florescent in situ hybridization showed new localization patterns for Hamiltonella in S. phillyreae, and the morphology of the bacteriosome differed from that observed in other whitefly species. Our results show new infections with bacterial symbionts in the whitefly species studied. Infections with the same symbionts in reproductively isolated whitefly species confirm complex relationships between whiteflies and bacterial symbionts, and suggest possible horizontal transfer of some of these bacteria.
CONCEALED BIRTHS, ADOPTION AND HUMAN RIGHTS LAW: BEING WARY OF SEEKING TO OPEN WINDOWS INTO PEOPLE'S SOULS
Authors: Marshall Jill 
Published: June 2012

AbstractAlthough rare, giving birth in secret or in concealed circumstances still happens in the United Kingdom. The new born child's existence is unknown to his or her biological ‘father’ and or to the wider biological family of the birth giver who wishes to place the child for adoption without his or her existence being revealed to them. Legal decisions need to be made judicially when a local authority seeks orders as to whether it is required to make further inquiries to identify and notify the biological father and or wider biological family as to any forthcoming adoption proceedings. Developments in European human rights law's protection of a right to respect one's private life provided by Article 8 of the European Convention on Human Rights (ECHR) towards a right to personal autonomy, identity and integrity can be interpreted in different ways. However, three positions are argued here to guard against an erosion of women's confidentiality and privacy in these circumstances. First, women's choices of concealment should be accepted with respect rather than perceived as inauthentic and therefore impermissible; this is in keeping with Article 2's right to life and Article 8's right to personal autonomy and integrity. Second, the right to family life protected by Article 8 of any wider biological family and father is not contravened by allowing women to give birth discreetly. Third, openness and transparency, when it comes to exact knowledge of one's parents in this context is not necessary for a child's identity rights, which are also protected by Article 8's right to personal identity, to be legally protected.
TO RANT, VENT AND CONVERSE: PROTECTING LOW LEVEL DIGITAL SPEECH
Authors: Rowbottom Jacob 
Published: June 2012

AbstractSeveral recent cases have highlighted the range of legal controls that can be applied to expression on social networks and other amateur digital content. This article identifies three trends in the regulation of digital communications. First, such communications are subject to a wide range of laws, including those primarily regulating the mass media, public order and targeted communications. Second, the persistence and searchability of digital messages make such communications more likely to come to the attention of litigators and prosecutors. Thirdly, that the established approach to freedom of expression under Article 10 of the ECHR tends to protect speech that is deemed to be of “high value”, and therefore does little to protect much internet content. This article calls for some greater protection to be afforded to communications that are casual and amateur. The freedom to converse outlined in this article does not call for absolute protection, but seeks to ensure that any controls on expression are proportionate. In particular, alternatives to the criminal law are considered.
GENERAL CLAUSES AND THE COMPETING ETHICS OF EUROPEAN CONSUMER LAW IN THE UK
Authors: Willett Chris 
Published: June 2012

AbstractEU ‘general clauses’ on fairness offer significant potential for improved consumer protection. However, the Supreme Court has interpreted the unfair terms general clause and a related provision by reference to an underlying ethic of self interest and self reliance'; and the same approach is possible under the unfair practices general clauses. This is a significant threat to consumer protection. A more protective ethic may be intended at EU level; and a particular line of argument may be needed to persuade the Supreme Court of this.

Authors: Wiegand S , Esters J , Müller H-H , Jäcker T , Roessler M , Fasunla J A , Werner J A , Sesterhenn A M 
Published: June 2012

AbstractObjectives:Dissection of neck levels I and IIB is time-consuming and can cause comorbidity. This study aimed to determine whether level I and IIB neck dissection was necessary in patients with laryngeal cancer and clinically detectable or nondetectable neck nodes.Patients and methods:This was a retrospective review of 73 patients with laryngeal cancer. Essential clinical data were obtained and analysed to determine the incidence of neck node metastasis in levels I and IIB.Results:Of the 48 patients with no clinically apparent neck nodes, none had level I metastases and only one had level IIB metastases. Of the patients with clinically detectable neck nodes, three of 21 patients had level I metastases and three of 25 patients had level IIB metastases; these six patients also had additional metastases in level IIA.Conclusion:Dissection of neck levels I and IIB is justifiable in laryngeal cancer patients with clinically detectable neck nodes and suspicious lymph nodes in the respective level or level IIA. However, in patients without clinically detectable neck nodes, preservation of levels I and IIB is oncologically safe, economical and reduces the risk of comorbidity.

Published: June 2012

AbstractObjective:To evaluate the haemostatic efficacy and safety of the LigaSure vessel sealing system in major head and neck cancer surgery.Methods:This two-year, prospective study included 34 patients who underwent major head and neck cancer surgery at a university hospital. The LigaSure Precise handpiece and LigaSure 8 vessel sealing system were utilised as the primary means of haemostasis, except when sealing vessels larger than 7 mm in diameter. Surgical outcomes were evaluated. In addition, in each patient the diameter of the largest vein and artery sealed (all were >2 mm) was measured before sealing.Results:In all cases except one (33/34 patients), a sutureless technique was performed. Post-operative bleeding was observed in two cases. Thirty veins and 22 arteries were measured. The mean diameter of the largest sealed vein was 3.8 mm, while that of the largest sealed artery was 2.7 mm.Conclusion:Our experience indicates that the surgical technique described is safe and effective. The main advantages of the LigaSure system are that it simplifies the procedure and eliminates the need for clips and suture ligations.
Practising to Know: Practicalism and Confucian Philosophy
Authors: Hetherington Stephen , Lai Karyn 
Published: June 2012

AbstractFor a while now, there has been much conceptual discussion about the respective natures of knowledge-that and knowledge-how, along with the intellectualist idea that knowledge-how is really a kind of knowledge-that. Gilbert Ryle put in place most of the terms that have so far been distinctive of that debate, when he argued for knowledge-how's conceptual distinctness from knowledge-that. But maybe those terms should be supplemented, expanding the debate. In that spirit, the conceptual option of practicalism has recently entered the fray. Practicalism conceives anew the nature of knowledge-that, as being a kind of knowledge-how. In this paper we enlarge upon this conceptual suggestion. We draw from an ancient Chinese text, theAnalects of Confucius, explaining how it lends some support to practicalism.
Authentic faith and acknowledged risk: dissolving the problem of faith and reason
Authors: MCKAUGHAN DANIEL J. 
Published: June 2012

AbstractOne challenge to the rationality of religious commitment has it that faith is unreasonable because it involves believing on insufficient evidence. However, this challenge and influential attempts to reply depend on assumptions about what it is to have faith that are open to question. I distinguish between three conceptions of faith (faith asbelief-plus,trusting acceptance, andhopeful affirmation) each of which can claim some plausible grounding in the Judaeo-Christian tradition. Questions about the rationality or justification of religious commitment and the extent of compatibility with doubt look different on accounts of faith in which trust or hope, rather than belief, are the primary basis for the commitments. On such accounts, while the person of faith has a stake in the truth of the content (e.g. that God exists), practical as well as epistemic considerations can legitimately figure in normative appraisals. Trust and hope can be appropriate in situations of recognized risk, need not involve self-deception, and are compatible with the idea that one's purely epistemic opinions should be responsive only to evidence.
The cognitive bases of human tool use
Authors: Vaesen Krist 
Published: June 2012

AbstractThis article has two goals. The first is to assess, in the face of accruing reports on the ingenuity of great ape tool use, whether and in what sense human tool use still evidences unique, higher cognitive ability. To that effect, I offer a systematic comparison between humans and nonhuman primates with respect to nine cognitive capacities deemed crucial to tool use: enhanced hand-eye coordination, body schema plasticity, causal reasoning, function representation, executive control, social learning, teaching, social intelligence, and language. Since striking differences between humans and great apes stand firm in eight out of nine of these domains, I conclude that human tool use still marks a major cognitive discontinuity between us and our closest relatives. As a second goal of the paper, I address the evolution of human technologies. In particular, I show how the cognitive traits reviewed help to explain why technological accumulation evolved so markedly in humans, and so modestly in apes.
Tool innovation may be a critical limiting step for the establishment of a rich tool-using culture: A perspective from child development
Authors: Beck Sarah R. , Chappell Jackie , Apperly Ian A. , Cutting Nicola 
Published: June 2012

AbstractRecent data show that human children (up to 8 years old) perform poorly when required to innovate tools. Our tool-rich culture may be more reliant on social learning and more limited by domain-general constraints such as ill-structured problem solving than otherwise thought.
Childhood and advances in human tool use
Authors: Nielsen Mark 
Published: June 2012

AbstractHuman life history incorporates childhood, a lengthy post-weaning period of dependency. This species-specific period provides an opportunity for extensive learning and for sophisticated cultural behaviors to develop, including crucial tool use skills. Although I agree that no individual cognitive trait singularly differentiates humans from other animals, I suggest here that without childhood, the traits that are key to human tool use would not emerge.
Language and tool making are similar cognitive processes
Authors: Holloway Ralph L. 
Published: June 2012

AbstractDesign features for language and stone toolmaking (not tool use) involve similar if not homologous cognitive processes. Both are arbitrary transformations of internal “intrinsic” symbolization, whereas non-human tool using is mostly an iconic transformation. The major discontinuity between humans and non-humans (chimpanzees) is language. The presence of stone tools made to standardized patterns suggests communicative and social control skills that involved language.
Not by thoughts alone: How language supersizes the cognitive toolkit
Authors: IJzerman Hans , Foroni Francesco 
Published: June 2012

AbstractWe propose that Vaesen's target article (a) underestimates the role of language in humans' cognitive toolkit and thereby (b) overestimates the proposed cognitive discontinuity between chimps and humans. We provide examples of labeling, numerical computation, executive control, and the relation between language and body, concluding that language plays a crucial role in “supersizing humans' cognitive toolkit.”
Thinking tools: Acquired skills, cultural niche construction, and thinking with things
Authors: Jeffares Ben 
Published: June 2012

AbstractThe investigative strategy that Vaesen uses presumes that cognitive skills are to some extent hardwired; developmentally plastic traits would not provide the relevant comparative information. But recent views of cognition that stress external resources, and evolutionary accounts such as cultural niche construction, urge us to think carefully about the role of technology in shaping cognition.
The limits of chimpanzee-human comparisons for understanding human cognition
Authors: Reader Simon M. , Hrotic Steven M. 
Published: June 2012

AbstractEvolutionary questions require specialized approaches, part of which are comparisons between close relatives. However, to understand the origins of human tool behavior, comparisons with solely chimpanzees are insufficient, lacking the power to identify derived traits. Moreover, tool use is unlikely a unitary phenomenon. Large-scale comparative analyses provide an alternative and suggest that tool use co-evolves with a suite of cognitive traits.
From individual cognition to populational culture
Authors: Vaesen Krist 
Published: June 2012

AbstractIn my response to the commentaries from a collection of esteemed researchers, I reassess and eventually find largely intact my claim that human tool use evidences higher social and non-social cognitive ability. Nonetheless, I concede that my examination of individual-level cognitive traits does not offer a full explanation of cumulative culture yet. For that, one needs to incorporate them into population-dynamic models of cultural evolution. I briefly describe my current and future work on this.
Anticipatory sentence processing in children with specific language impairment: Evidence from eye movements during listening
Authors: ANDREU LLORENÇ , SANZ-TORRENT MÒNICA , TRUESWELL JOHN C. 
Published: June 2012

ABSTRACTTwenty-five children with specific language impairment (SLI; age 5 years, 3 months [5;3]–8;2), 50 typically developing children (3;3–8;2), and 31 normal adults participated in three eye-tracking experiments of spoken language comprehension that were designed to investigate the use of verb information during real-time sentence comprehension in Spanish. In Experiment 1, participants heard sentences like El niño recorta con cuidado el papel (The boy trims carefully the paper) in the presence of four depicted objects, only one of which satisfied the semantic restrictions of the verb recorta (e.g., paper, clock, fox, and dinosaur). Eye movements revealed that children with SLI, like other groups, were able to recognize and retrieve the meaning of the verb rapidly enough to anticipate the upcoming semantically appropriate referent, prior to actually hearing the noun phrase el papel (the paper). Experiments 2 and 3 revealed that for all groups of participants, anticipatory eye movements were also modulated by the semantic fit of the object serving as the patient/theme of the verb. Relatively fine-grained semantic information of a verb was computed fast enough even by children with SLI to result in anticipatory eye movements to semantically appropriate referents. Children with SLI did differ from age-matched controls, but only slightly in terms of overall anticipatory looking at target objects; the time course of looking between these groups was quite similar. In addition, no differences were found between children with SLI and control children matched for mean length of utterance. Implications for theories that characterize SLI are discussed.
Understanding institutional conversion: the case of the National Reporting and Learning System
Authors: Dodds Anneliese , Kodate Naonori 
Published: June 2012

AbstractThis article focuses on one type of institutional change: conversion. One innovative approach to institutional change, the “political-coalitional approach”, acknowledges that: institutions can have unintended effects, which may privilege certain groups over others; institutions are often created and sustained through compromise with external actors; and institutions’ external context can vary significantly over time, as different coalitions’ power waxes and wanes. This approach helps explain the conversion of one institution drawn from the UK National Health Service, the National Reporting and Learning System. However, the shift of this system from producing formative information to facilitate learning to promote safer care, towards producing summative information to support resource allocation decisions, cannot be explained merely by examining the actions of external power coalitions. An internal focus, which considers factors that are normally viewed as “organisational” (such as leadership and internal stability), is also required.
Complexity, coupling and policy effectiveness: the European response to the Greek sovereign debt crisis
Authors: Zahariadis Nikolaos 
Published: June 2012

AbstractWhat is the impact of Greece's fiscal meltdown on the effectiveness of Europe's response? Using Perrow's normal accidents theory, I argue that efforts to reduce the likelihood of a Greek default activated conflicting centripetal and centrifugal modes of governance. Greater centralisation in decision-making at the European Union level improves policy effectiveness because it addresses problems of contagion but it simultaneously raises the risk of overall failure by increasing diagnosis, coordination and compliance costs. Three episodes are explored: the first bailout in May 2010, the mid-term fiscal strategy in June–July 2011 and the second bailout in February 2012. Implications are drawn for theories of delegation, intergovernmentalism and the future of EU crisis management.
