The galactic magnetic field (GMF) and the intergalactic magnetic field (IGMF) affect the propagation of ultra-high energy cosmic rays (UHECRs) from the source to us. Here we examine the in uences of the GMF/IGFM and the dependence of their sky distribution on galactic latitude, b. We analyze the correlation between the arrival direction (AD) of UHECRs observed by the Pierre Auger Observatory and the large-scale structure of the universe in regions of sky divided by b. Specifically, we compare the AD distribution of observed UHECRs to that of mock UHECRs generated from a source model constructed with active galactic nuclei. Our source model has the smearing angle as a free parameter that re ects the de ection angle of UHECRs from the source. The results show that larger smearing angles are required for the observed distribution of UHECRs in lower galactic latitude regions. We obtain, for instance, a 1σ credible interval for smearing angle of 0° ≤ θs ≤ 72° at high galactic latitudes, 60° < b ≤ 90°, and of 75° ≤ θs ≤ 180°, -30° ≤ b ≤ 30°, at low galactic latitudes, respectively. The results show that the in uence of the GMF is stronger than that of the IGMF. In addition, we can estimate the strength of GMFs by these values; if we assume that UHECRs would have heavier nuclei, the estimated strengths of GMF are consistent with the observational value of a few μG. More data from the future experiments may make UHECR astronomy possible.

Paying close attention to those new to an organization, whether fresh or experienced, whose primary interest is in (re)socialization, the current study intends to (1) further the concept of mentoring from a bilateral relationship to a community and culture fostered by developmental networks, (2) propose an integrated conceptual framework for organizational socialization, and (3) suggest implications for practice and future research. This study reviews, analyzes, and integrates research assets and subsequently re-conceptualizes the aggregate information as valid propositions and a conceptual framework. The findings include (1) 11 propositions regarding the relationships among network characteristics (embeddedness, diversity), developmental functions (career support, psychosocial support, and role modeling), and socialization outcomes (learning and attitudinal outcomes); and (2) an integrated conceptual framework that depicts a comprehensive mechanism through which developmental networks conduce to organizational socialization of newcomers. Implications are that developmental networking must be an individual’s fundamental competency and an essential part of organizational onboarding processes, and imperative for both members’ career development and innovative organizational culture. By integrating research assets on the developmental phenomenon into conceptualizations, this study furthers the concept of mentoring to organizational culture and stimulates a substantive discourse for theory-building towards organizational socialization from the developmental network perspective.

The blastocyst should initiate the dynamic changes in morphology and gene expression during hatching and implantation. Blastocyst morphogenesis includes two major events as the formation of blastocoel cavity for lineage differentiation into trophectoderm and inner cell mass, and the blastocyst hatching for implantation. However, there is little known about the relation of dynamic morphogenesis in blastocyst with hatching and implantation potential. In this study, we investigated effects of the dynamic morphogenesis in blastocyst on hatching and implantation potential by outgrowth assay. The cumulative time between each stages was calculated and analyzed. The feature of contraction was evaluated as follows: the number of contractions and the period of circumference was measured. The percentage of reduction during contraction was classified as weak when it was less than 20% and as strong when 20% or more. Compared to embryos of hatching group, embryos of non-hatching group were significantly delayed time at the compacted morula stage by 375.3 min (p<0.05) and at the early blastocyst stage by 650.1 min (p<0.01), respectively. Compared to blastocysts of outgrowth group, blastocysts of non-outgrowth group were significantly delayed at the compacted morula by 404.0 min (p<0.01) and at the early blastocyst stage by 535.4 min (p<0.01), respectively. There is no significant difference in the feature of contraction between hatching and non-hatching groups. However, blastocyst of outgrowth group showed more number of weak contraction and less number of strong contractions, compared with blastocysts of non-outgrowth group (p<0.01). Period of circumference was not significantly different in hatching and outgrowth process. These results suggested that time of blastocoel formation and number of weak contraction in blastocysts were closely related to hatching and outgrowth potential. Dynamic changes of blastocyst formation and contraction could be useful markers to select embryos for predicting the success implantation and pregnancy in human ART program.
