<p>This review comments upon the article entitled above. The article is well written and describes an interesting and original study. This review critiques the Method and Discussion sections of the article and offers suggestions for future research. Three specific points from the method are considered relating to: dual roles as researcher-musicians, the use of reflective diaries in research, and the impact on the research of the prior relationship between the authors. The unique role of &ldquo;written empathy&rdquo; is discussed within the context of empathic relationships. Also, this review considers how shifts from verbal to non-verbal communication may indicate movement from a &ldquo;top-down&rdquo; to &ldquo;bottom up&rdquo; response, and how this shift is related to &ldquo;empathetic attunement.&rdquo;</p>

The use of diaphragm wall to protect the depth excavation is quite common in Viet Nam. Prediction of diaphragm wall deformations is required to choose the method of construction, and also for control of process of erection of an underground construction. Currently, there are many programs to calculate the deformation of the diaphragm wall, including software Plaxis. This paper considers the choice of a computational model for soils in the Hanoi - Viet Nam region of Mohr Coulomb (MC) and Hardening Soil (HS) and comparison of the calculation results with the measured data. Such investigations were conducted first.

The literature portrays globalisation as a ‘Janus-like phenomenon’, implying that it has two ‘heads’ like the mythical giant Janus; beyond the rise of hyber-liberalism, xenophobia and socio-economic inequity, globalisation has also humanistic and democratic elements. In this context, a global agenda of social justice and equity of educational opportunity appears to be counteracted by global discourses of neoliberalism, which are embedded in international performance indicators, and international tests and scores. Apparently, teachers in the era of globalisation are assigned with diverse, and often ‘unbalanced’, social and professional roles. In such a context, this article aims to address the following question: What roles are teachers called to play in the epoch of globalisation? In this article, we acknowledge that global preoccupation with efficiency and performance has contributed to the development a managerialist model of education causing the de-professionalisation of teachers. Such model has in turn restricted teachers’ opportunities to mediate social justice. Nonetheless, what we conclude is that teachers are not ‘trapped’ in a trade-off between efficiency and equity. Even if we accept that neoliberalism is an inevitable top-down policy framework, neoliberal settings can still provide spaces for teachers to act as democratic agents by developing autonomous, active and collegial professional identities. However, this article concludes that teachers working in solidarity in local/global coalitions may counteract the hegemony of neoliberalism by bringing bottom-up structural transformation towards social justice, equity and diversity recognition.

AbstractThis work presents the geotechnical problems occurring in the interaction area between road embankments and the bridge structures in case a subsoil characterised by complex and complicated geological and engineering conditions. These significant problems that occur during the design, performance and exploitation of the abutment structures, are illustrated on the example of engineering practice in Lower Silesia, concerning a road embankment that constitutes access to the bridge. The results of numerical analyses concerning the process of consolidation of low-strength soils and their impact on the settlements of road embankment indicate the need to carry out such analyses also in the cases, when the soft soils occur in the direct geotechnical layer under the designed embankment. The Authors included in this article a discussion regarding other effective actions and solutions that can be used in the design and performance phase, leading to the elimination or reduction of problems concerning the connection of engineering structures with road embankments, which have been recurring for years, ultimately resulting in the improvement of quality, comfort and safety of road exploitation.

ABSTRACT This paper complements the ongoing empirical discussion surrounding participative budgeting by comparing its economic merits relative to a top-down budgeting alternative. In both budgeting regimes, private information is communicated vertically between a principal and a manager. We show that top-down budgeting incurs fewer agency costs than bottom-up budgeting whenever the level of information asymmetry is relatively low. Although the choice between top-down and bottom-up budgeting ultimately determines who receives private information within the firm, we find that both the principal and manager's preferences over the allocation of private information remain qualitatively similar across the two budgeting paradigms. Specifically, while the principal always prefers either minimal or maximal private information, the manager prefers an interim or maximal level of private information regardless of who is privately informed. Last, we use our model to address empirical inconsistencies relating the firm's choice of budgeting process, the resulting budgetary slack, and performance.
