- Residing with the exponential growth of gastronomy tourism research, a number of review articles have examined the relationship of gastronomy and tourism from distinct thematic and disciplinary perspectives. What remains absent is a comprehensive overview that encapsulates the interdisciplinary dimensions of this area of research. In response, this study comprehensively investigates gastronomy tourism literature utilizing a network and content analysis, with an aim to map the main subject areas concerned with gastronomy tourism and relations between varying subject areas. In doing so, themes determining gastronomy tourism and focus for future exploration are identified. The review findings suggest that the trajectory of gastronomy tourism research is characterized by the dominance of "tourism, leisure, and hospitality management" and "geography, planning, and development." Three recommendations are proposed to assist development of gastronomy tourism research: increased dialogue across subject areas, development of critical and theoretical approaches, and greater engagement with sustainability debates.

Alignment delays in the N = Z nuclei Kr-72, Sr-76, and Zr-80

- The ground state rotational bands of the N = Z nuclei Kr-72, Sr-76, and Zr-80 have been extended into the angular momentum region where rotation alignment of particles is normally expected. By measuring the moments of inertia of these bands we have observed a consistent increase in the rotational frequency required to start pair breaking, when compared to neighboring nuclei. Kr-72 shows the most marked effect. It has been widely suggested that these delayed alignments arise from np-pairing correlations. However, alignment frequencies are very sensitive to shape degrees of freedom and normal pairing, so the new experimental observations are still open to interpretation.

Testing mean-field models near the N=Z line : gamma-ray spectroscopy of the T-z=1/2 nucleus Kr-73

- Excited states in the N=Z+1 nucleus Kr-73 have been investigated using the Ca-40(Ar-36,2pn) and Ca-40(Ca-40,alpha2pn) reactions at 145 and 160 MeV, respectively. gamma rays were detected using the Gammasphere array and events were recorded in coincidence with charged-particle and neutron detectors. The three previously observed bands were extended to high spin, and a new unfavored positive-parity band has been observed. The alignment characteristics and decay properties of the bands are all consistent with large-deformation prolate rotation, with no clear evidence for oblate bands or shape coexistence. This is quite different from neighboring Kr-72,Kr-74, indicating a strong shape-stabilizing role for the valence neutron. The experimental results are compared to extended total Routhian surface, cranked Nilsson Strutinsky, and cranked relativistic mean-field calculations. The results suggest that the paired calculations lack some important physics. Neutron-proton correlations may be the missing ingredient. There is also evidence for an unusual band crossing in the negative-parity bands, which may indicate the presence of T=0 pairing correlations. At high spin all the models can reproduce the experimental data.
