Economics of education research: a review and future prospects
In this paper we offer an appraisal of the economics of education research area, charting its history as a field and discussing the ways in which economists have contributed both to education research and to education policy-making. In particular, we highlight the theoretical and methodological contributions that economists have made to the field of education during the last 50 years. Despite the success of the economics of education as a field of inquiry, we argue that some of the contributions made by economists could be limited if the economics of education is seen as quite distinct from the other disciplines working in the field of education. In these areas of common interest, economists need to work side by side with the other major disciplines in the field of education if their contribution to the field is to be maximised, particularly in terms of applying improved methodology. We conclude that the study of education acquisition and its economic and social impact in the economics of education research area is very likely to remain a fertile research ground. Acknowledgement
Synchronization of active mechanical oscillators by an inertial load
Motivated by the operation of myogenic (self-oscillatory) insect flight
muscle, we study a model consisting of a large number of identical oscillatory
contractile elements joined in a chain, whose end is attached to a damped
mass-spring oscillator. When the inertial load is small, the serial coupling
favors an antisynchronous state in which the extension of one oscillator is
compensated by the contraction of another, in order to preserve the total
length. However, a sufficiently massive load can sychronize the oscillators and
can even induce oscillation in situations where isolated elements would be
stable. The system has a complex phase diagram displaying quiescent,
synchronous and antisynchrononous phases, as well as an unsual asynchronous
phase in which the total length of the chain oscillates at a different
frequency from the individual active elements.Comment: 5 pages, 4 figures, To appear in Phys. Rev. Let
tert-Butyl N-hydroxy-N-[(1S*,2R*)-2-(1-naphthyl)cyclopent-3-en-1-yl]carbamate
The relative stereochemistry of the title compound, C20H23NO3, was established by X-ray analysis. The asymmetric unit contains two independent molecules. In the crystal structure, each type of molecule forms a centrosymmetric dimer via pairs of intermolecular O—H⋯O hydrogen bonds, resulting in an R

Overeducation across British regions
This paper analyses levels of over-education and wage returns to education for males across
eleven regions of the UK using Labour Force Survey data. Significant differences are found
in the probability of being over-educated across regions; also, differences are found in the
return to the ‘correct’ level of education in each region, in each case associated with
flexibility of movement between and into particular regions, which determines the ease of job
matching. Furthermore, evidence is found that, after controlling for the level of education
acquired, there exists a premium to the ‘correct’ level of education, which varies across UK
regions
Beating patterns of filaments in viscoelastic fluids
Many swimming microorganisms, such as bacteria and sperm, use flexible
flagella to move through viscoelastic media in their natural environments. In
this paper we address the effects a viscoelastic fluid has on the motion and
beating patterns of elastic filaments. We treat both a passive filament which
is actuated at one end, and an active filament with bending forces arising from
internal motors distributed along its length. We describe how viscoelasticity
modifies the hydrodynamic forces exerted on the filaments, and how these
modified forces affect the beating patterns. We show how high viscosity of
purely viscous or viscoelastic solutions can lead to the experimentally
observed beating patterns of sperm flagella, in which motion is concentrated at
the distal end of the flagella
The role of familial habitus in shaping children's views of their future employment
As the field of Geographies of Children, Youth and Families grows and diversifies as a testament to the active and vigorous interest in this area of research, the collection of papers presented within this Special Issue proves timely in addressing developing research on education and aspiration. At a variety of spatial scales and from different perspectives, the contributors have shown how educational settings are invoked by politicians, educators and practitioners as sites where the aspirations of future citizen-workers can be managed for perceived individual and collective benefit. It is unsurprising that young people remain the focus of policy attention and analyses in relation to ‘raising’ aspirations, given normative understandings of their chronological proximity to transitions to adulthood. What emerges alongside efforts to affect the aspirations of young people through education is a strand of thought which acknowledges the role of the family in the lives of young people. Research has shown distinctions in parental aspirations for their children according to ethnic and socio-economic background (Coleman, 1988; Portes and MacLeod, 1996), and has highlighted how families are viewed by educationalists as key to the academic success of their children (Holloway and Pimlott-Wilson, this issue). Whilst young people and parents remain central to considerations of aspiration (Nairn et al., 2007), the hopes of young children are also crucial when we take into account the implications which may arise when children judge one path of action feasible as a future goal whilst others appear unattainable.
In this article, I argue that the voices of children need to be included in research which considers aspiration, acknowledging the influence of the family on these imagined futures whilst also recognising that children reflexively develop their own perspectives as they encounter new experiences. In the next section of the paper, I engage with policy interest in families and discuss further my conceptualisation of habitus and how this relates to children’s hopes for the future. In the central section I present a case study of children’s future employment plans, putting forward evidence to show that family socialisation predisposes children to consider particular occupational types over others. To this end, I utilise the concept of habitus as a flexible and non-deterministic method for understanding children’s perceptions of what courses of action are most appropriate for their future. Thirdly, I provide evidence to suggest that children’s aspirations are not simply a reflection of parental practices but rather show how the habitus is continually evolving, illustrating children’s agency in their reflexive resistance of particular occupational types in light of family experience. In conclusion, the article calls for further consideration of children’s hopes for the future and the factors which influence the dispositions of individuals, highlighting the imperative for educationalists to remain cognisant of children’s dispositions in efforts to (re)shape aspirations
Disclosing physician ratings: performance effects and the difficulty of altering rating consensus
I examine effects of a health care system's policy to publicly disclose patient ratings of its physicians. I find evidence that this policy leads to performance improvement by the disclosed, subjective ratings and also by undisclosed, objective measures of quality. These effects are consistent with multitasking theory, in that physicians respond to the disclosure by providing more of a shared input—time with patients—that benefits performance by ratings and underlying quality. I also find, as predicted by information cascade theory, that the ratings become jammed to some degree near initially disclosed values. Specifically, raters observe the pattern of initial ratings and follow suit by providing similar ratings. Finally, I find evidence that physicians anticipate rating jamming and so concentrate their effort on earlier performance in order to set a pattern of high ratings that later ratings follow. These results demonstrate that the disclosure of subjective ratings can benefit performance broadly but can also shift effort toward earlier performance
