China's policy on rural-urban migrants and urban social harmony

Rural migrants have suffered from serious social exclusion in the Chinese urban society. However, since the early 2000s, the Chinese government emphasizes social harmony as an important national development goal. Together with the reorientation of development goals, the livelihood of rural migrants has received unprecedented State attention. This paper studies the policy changes and examines whether they have enhanced urban social harmony, particularly, in improving the welfare of rural migrants. It was found that the policy changes only partially restored the social and political rights of rural migrants. Some rural migrants have resorted to extreme actions, such as suicides, crimes, and strikes, to express their grievances, thereby contradicting government attempts to ensure social harmony. Further efforts are required to enhance the social inclusion of rural migrants in urban China.published_or_final_versio

Fast quantum information transfer with superconducting flux qubits coupled to a cavity

We present a way to realize quantum information transfer with superconducting flux qubits coupled to a cavity. Because only resonant qubit-cavity interaction and resonant qubit-pulse interaction are applied, the information transfer can be performed much faster, when compared with the previous proposals. This proposal does not require adjustment of the qubit level spacings during the operation. Moreover, neither uniformity in the device parameters nor exact placement of qubits in the cavity is needed by this proposal.Comment: 6 pages, 3 figure

Transcriptional profiling of the pea shoot apical meristem reveals processes underlying its function and maintenance

<p>Abstract</p> <p>Background</p> <p>Despite the importance of the shoot apical meristem (SAM) in plant development and organ formation, our understanding of the molecular mechanisms controlling its function is limited.

Crying in Psychotherapy: The Perspective of Therapists and Clients

Eighteen U.S.-based doctoral students in counseling or clinical psychology were interviewed by phone regarding experiences of crying in therapy. Specifically, they described crying as therapists with their clients, as clients with their therapists, and experiences when their therapists cried in the participants’ therapy. Data were analyzed using consensual qualitative research. When crying with their clients, therapists expressed concern about the appropriateness/impact of crying, cried only briefly and because they felt an empathic connection with their clients, thought that the crying strengthened the relationship, discussed the event with their supervisor, and wished they had discussed the event more fully with clients. Crying as clients was triggered by discussing distressing personal events, was accompanied by a mixture of emotions regarding the tears, consisted of substantial crying to express pain or sadness, and led to multiple benefits (enhanced therapy relationship, deeper therapy, and insight). When their therapists cried, the crying was brief, was triggered by discussions of termination, arose from therapists’ empathic connection with participants, and strengthened the therapy relationship. Implications for research, training, and practice are presented

Phase separation and vortex states in binary mixture of Bose-Einstein condensates in the trapping potentials with displaced centers

The system of two simultaneously trapped codensates consisting of $^{87}Rb$ atoms in two different hyperfine states is investigated theoretically in the case when the minima of the trapping potentials are displaced with respect to each other. It is shown that the small shift of the minima of the trapping potentials leads to the considerable displacement of the centers of mass of the condensates, in agreement with the experiment. It is also shown that the critical angular velocities of the vortex states of the system drastically depend on the shift and the relative number of particles in the condensates, and there is a possibility to exchange the vortex states between condensates by shifting the centers of the trapping potentials.Comment: 4 pages, 2 figure
