Carrier-Concentration Dependence of the Pseudogap Ground State of Superconducting Bi2Sr2-xLaxCuO6+delta Revealed by 63,65Cu-Nuclear Magnetic Resonance in Very High Magnetic Fields
We report the results of the Knight shift by 63,65Cu-nuclear-magnetic
resonance (NMR) measurements on single-layered copper-oxide
Bi2Sr2-xLaxCuO6+delta conducted under very high magnetic fields up to 44 T. The
magnetic field suppresses superconductivity completely and the pseudogap ground
state is revealed. The 63Cu-NMR Knight shift shows that there remains a finite
density of states (DOS) at the Fermi level in the zero-temperature limit, which
indicates that the pseudogap ground state is a metallic state with a finite
volume of Fermi surface. The residual DOS in the pseudogap ground state
decreases with decreasing doping (increasing x) but remains quite large even at
the vicinity of the magnetically ordered phase of x > 0.8, which suggests that
the DOS plunges to zero upon approaching the Mott insulating phase.Comment: 4 pages, 5 figures, to appear in Phys. Rev. Let
Complaint Management in the Public Sector Organization in the Philippines
Participatory governance is a democratic process intended to involve citizens in the management of public institution. By providing them platforms through which they can access the government, transparency and accountability in public governance is enhanced. The Department of Public Works and Highways (DPWH) acknowledges its importance through the establishment of different platforms of communications wherein clients can raise their concerns. The study aims at describing and evaluating the Complaints Management Program of the DPWH Nueva Ecija 2nd District Engineering Office based in Cabanatuan City. The analysis was drawn from Fifteen (15) client feedbacks received in 2017. The data were gathered using qualitative and quantitative approaches while multi-stakeholders framework for complaint management was adapted to measure the effectiveness of the feedback and complaint management mechanisms of the agency. The study found that the agency : a) institutionalizes and observes procedures in handling complaints; b) resolves complaints based on the principles of fairness, accessibility, responsiveness, efficiency , trust and citizens participation; however, there are limitations identified in regard to the administrative support in terms of personnel assigned, training and availability of vehicle use to verify various complaints on the ground. Civic engagement is an effective tool to promote democracy and enhance open government. They are proven to create enabling environment that tends to yield positive political outcomes and policy implementation results.

Office Bullying in the Philippines and the Need for Public Policy
There is an urgent need to solve the problem of workplace bullying in both private and government sectors. Bullying at work creates serious negative consequences to the victims and the organization affecting their productivity. The magnitude of the problem necessitates state intervention to correct market and government failures. This policy paper studies office bullying and the need to legislate to realize efficient and effective allocation of government and private resources. It is guided by the Constitutional mandate that maintenance of peace, harmony, health and safety at work is an inherent duty of the State because of its inherent power to issue orders and command obedience to mitigate its effects. Using Cost Benefit Analysis, Institutional Analysis to policy making, and Rational-Decision making as tools for analysis, crafting and passing upon a statute is the most feasible means to address the problem of workplace bullying. The need to legislate a national policy on workplace bullying is necessary to mitigate its negative consequences both to employees and organizational productivity. Office bullying as a public issue also requires strict monitoring and evaluation of the implementation of similar or related laws may also address the problems cause by the same destructive behaviors but are inadequately explored in many researches
Transparency and Accountability in Local Governance: The Nexus Between Democracy and Public Service Delivery in the Philippines
Transparency effectiveness cannot take place without accountability. Democracy as a form of government necessitates popular support which cannot be given by the people unless trust and confidence to a public institution are maintained. The study discusses the concept of transparency and accountability in the context of a democratic system and its role in enhancing people's trust to public institutions. From the perspective of democracy, the direct link between public service delivery and democracy through the intermediacy of transparency and accountability is established.

Antiferromagnetic Switching Driven by the Collective Dynamics of a Coexisting Spin Glass
The theory behind the electrical switching of antiferromagnets is premised on
the existence of a well defined broken symmetry state that can be rotated to
encode information. A spin glass is in many ways the antithesis of this state,
characterized by an ergodic landscape of nearly degenerate magnetic
configurations, choosing to freeze into a distribution of these in a manner
that is seemingly bereft of information. In this study, we show that the
coexistence of spin glass and antiferromagnetic order allows a novel mechanism
to facilitate the switching of the antiferromagnet FeNbS,
which is rooted in the electrically-stimulated collective winding of the spin
glass. The local texture of the spin glass opens an anisotropic channel of
interaction that can be used to rotate the equilibrium orientation of the
antiferromagnetic state. The use of a spin glass' collective dynamics to
electrically manipulate antiferromagnetic spin textures has never been applied
before, opening the field of antiferromagnetic spintronics to many more
material platforms with complex magnetic textures.Comment: 7 pages, 4 Figures, supplement available on reasonable reques
Local festivals, social capital and sustainable destination development: experiences in East London
This paper explores the nature of social capital arising from engagement in local festivals and the implications of this for the social sustainability of an emerging destination. Two case studies are developed from a longitudinal research project which investigates local festivals staged in the Hackney Wick and Fish Island area adjacent to Queen Elizabeth Olympic Park in East London, UK between 2008 and 2014. This area has been directly affected by extensive development and regeneration efforts associated with the staging of the London 2012 Olympic Games. The two festivals considered here respond to the challenges and opportunities arising for local people as the area changes. One festival aims to foster a sense of community by creating shared experiences and improving communication across diverse groups. The other draws together the cultural community, links them to the opportunities arising as the area emerges as a destination, and attracts visitors. These festivals increase social capital in the area, but its distribution is very uneven. The accrual of social capital exacerbates existing inequalities within the host community, favouring the “haves” at the expense of the “have nots”. There are tensions between the development of social capital and social sustainability in this emerging destination
Self-control enhancement in children:Ethical and conceptual aspects
Childhood self-control is currently receiving great scientific and public attention because it could predict much of adult’s life success and well-being. Specialized interventions based on findings in social psychology and neuroscience potentially enhance children’s capacity to exercise self-control. This perspective triggers hopes that self-control enhancement allows us to say good-bye for good to potentially unsafe psychopharmacological agents and electronic brain stimulants. This chapter provides an in-depth ethical analysis of pediatric self-control enhancement and points toward a series of serious conceptual and ethical concerns. First, it gives an overview of current psychological as well as neuroscientific research on self-control, and it presents longitudinal studies that emphasize the importance of childhood self-control for adult life success. Second, it critically discusses the concept of self-control presupposed in these approaches and points to crucial limitations. Going beyond an understanding of self-control as a sophisticated means of goal-achievement, i will argue for a comprehensive understanding that takes the inherent normativity of self-controlled behavior seriously. In that context, self-control enhancement appears as not necessarily desirable and occasionally even detrimental. Finally, this chapter questions the notion of childhood implicit in current research and how values typically put on this phase of life could get affected by self-control enhancement. I finish with an exploration of the conditions under which pediatric self-control enhancement is either impermissible, permissible, or maybe obligatory
