Was the Higgs boson discovered?
The standard model has postulated the existence of a scalar boson, named the
Higgs boson. This boson plays a central role in a symmetry breaking scheme
called the Brout-Englert-Higgs mechanism (or the
Brout-Englert-Higgs-Guralnik-Hagen-Kibble mechanism, for completeness) making
the standard model realistic. However, until recently at least, the
50-year-long-sought Higgs boson had remained the only particle in the standard
model not yet discovered experimentally. It is the last but very important
missing ingredient of the standard model. Therefore, searching for the Higgs
boson is a crucial task and an important mission of particle physics. For this
purpose, many theoretical works have been done and different experiments have
been organized. It may be said in particular that to search for the Higgs boson
has been one of the ultimate goals of building and running the LHC, the world's
largest and most powerful particle accelerator, at CERN, which is a great
combination of science and technology. Recently, in the summer of 2012, ATLAS
and CMS, the two biggest and general-purpose LHC collaborations, announced the
discovery of a new boson with a mass around 125 GeV. Since then, for over two
years, ATLAS, CMS and other collaborations have carried out intensive
investigations on the newly discovered boson to confirm that this new boson is
really the Higgs boson (of the standard model). It is a triumph of science and
technology and international cooperation. Here, we will review the main results
of these investigations following a brief introduction to the Higgs boson
within the theoretical framework of the standard model and Brout-Englert-Higgs
mechanism as well as a theoretical and experimental background of its search.
This paper may attract interest of not only particle physicists but also a
broader audience.Comment: LateX, 23 pages, 01 table, 9 figures. To appear in Commun. Phys.

The development of a contextualised set of evaluation criteria for studying internationalisation at a Vietnamese public university : a dissertation presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Education at Massey University, Manawatū, New Zealand
The aim of this thesis is to explore the development of a contextualised set of evaluation criteria for studying internationalisation at a Vietnamese public university. The literature on internationalisation has so far paid little attention to Vietnam, a context which is at an early stage in conceptualising a plan for its internationalisation. This thesis, therefore, will assist Vietnamese universities in this effort in order to become a part of the global higher education system. Having access to a set of relevant evaluation criteria will not only enable them to better understand their current level of internationalisation but also inform their future internationalisation strategy.
The research process was supported by two conceptual frameworks: practical participation evaluation and utilization-focused evaluation approaches. A mixture of qualitative and quantitative research methods was employed to conduct the three-phase development of the contextualised set of evaluation criteria. A collaborative partnership was also developed with the institutional stakeholders from a key university for which the set of criteria was contextualised for evaluating the internationalisation process.
The findings from this study indicated that the development of a contextualised set of evaluation criteria for internationalisation at a Vietnamese public university was informed by a complexity of contextual factors. In particular, the domestic-focused nature of institutional internationalisation was found to be shaped not only by national economic and political rationales but also the institutional structure of single focus on teaching. The complexity was further expanded to (national) cultural relevance, institutional purposes for the evaluation, and the institutional mono-disciplinary structure when it came to the evaluation of that internationalisation. As a result of the study, a modelling process for developing a contextualised set of criteria for internationalisation at Vietnamese public universities was established.
Insights into the complexity of the process for contextualising a set of evaluation criteria to study internationalisation at a Vietnam university also led to implications and recommendations for institutional stakeholders at the key university in the study (policy implementers and senior leaders), other universities, and policy makers
EFL HIGH-SCHOOL TEACHERS’ PRACTICES OF STRATEGIES FOR CRITICAL THINKING INSTRUCTION IN WRITING CLASSES
This study aims to investigate EFL high-school teachers’ practices of strategies for CT instruction in their writing classrooms. The study was designed as a mixed-method one, using a questionnaire, and classroom observation as collecting data instruments. The sample consists of 103 EFL teachers from 21 high schools in Camau province, in the Mekong Delta region for quantitative data; five out of 103 teachers were purposely chosen to be observed to collect qualitative data. The finding of the study revealed that EFL high-school teachers’ practices of CT strategies used in writing classrooms were at a high level but at the lowest rate. At the same time, the results from classroom observation showed that EFL teachers used three more including setting real writing tasks, presentation, and student questioning in addition to the seven CT strategies presented in the research. From the findings, some pedagogical implications and recommendations are promoted in the hope that EFL teachers can effectively employ strategies for teaching CT in writing classrooms. Finally, the study’s limitations and suggestions for further research were also highlighted. Article visualizations

Mediating Effect of Social Commerce Continuance Use Intention on the Relationship Between Perceived Values and Brand Loyalty
The purpose of this paper is to examine the mediating effect of social commerce continuance use intention on the relationship between perceived values and brand loyalty in the social commerce context. The data was collected from 176 members of the Apple Watch Social Commerce site in Vietnam via an online questionnaire. Applying the structural equation modelling method, we found that social commerce continuance use intention has mediating effects on the relationship between perceived values and brand loyalty.
