Full textAbstract:
Integral study of brand name translation needs promoting theoretical category system at relevant macro-meso-micro contextual levels. Taken E-C brand name translation as example, this paper establishes an explanatory frame of generation and construction of “meaning-senses” of translated brand name through discussing the macro-meso-micro contexts and their major factors in the process of brand name translation. This research shows that “named meaning”, determined by meso brand contextual factors, should be jointly delivered by micro linguistic contextual factors complying with demands of macro cultural contexts. This research will provide a feasible research dimension for systematic integration of theoretical categorization of pragmatic translation.

Micro, meso and macro are levels or scales that can and may be mobilised in social analysis. This paper aims to contribute to the reflection and discussion, in particular, of the use of the meso level in the apprehension of social reality, in its potential advantages and disadvantages. For this purpose, a document collection and selection was carried out. Furthermore, the authors’ experience in teaching and research in social sciences, especially in the area of Sociology, was also used. This analytical exercise allows concluding that the meso-social level is mobilised in some perspectives, focusing in a privileged way on the group or the organisation as a structure and intermediate process between the other two levels. As for implications, it may be asserted that the meso level only has heuristic capabilities in the interpretation of a particular social context if the other two levels are not neglected in the analysis.

Life in any modern city of the world is concentrated mostly in a particular ever‐changing environment. Micro, meso and macro environments have a direct impact on sustainable urban development opportunities. This may facilitate sustainable urban development or, on the contrary, it may create constraints. Micro, meso and macro environments must be considered as an aggregate of forces influencing sustainable urban development and combining both the factors that have a direct impact and those whose impact is indirectly. This researches aim was to develop a model of sustainable urban development formation by undertaking a complex analysis of micro, meso and macro environmental factors affecting it and to present recommendations for the increase of its competitive abilities.

Full textAbstract:
Purpose The purpose of this paper is to advance our understanding of competitiveness. The authors introduce the concept of Competitive Productivity (CP), supplementing shortcomings of traditional understandings of national, organisational and individual productivity which overlook the nature of competitiveness, i.e. outperforming the competition, or at least bettering one’s own performance. The authors offer definitions, components and construct measurements of CP at three levels: macro, meso and micro. Design/methodology/approach A review of the literature was conducted to evaluate the need for combining productivity and competitiveness into one new construct. There are theories that combine these ideas – e.g., the resource-based theory of the firm – but the authors are presenting these concepts differently, or in a novel way. The authors’ focus on CP makes necessary a new group of construct measures which are different from that of the strategy literature: the authors measure an agent’s tendency “to be better than the competition” along multiple dimensions. Based on the CP construct, the authors present three testable models to uncover determinants of CP at three levels (macro, meso and micro). Finally, the work around “emergent property” can be applied to examine CP itself as being a determinant for other higher-order outcomes such as welfare, profits and life satisfaction. CP forms a platform to explore likely interplay (bottom-up and/or top-down mechanisms) within the micro–meso–macro architecture. Findings Three CP models were developed and are briefly discussed in this paper: first, a National Competitive Productivity (NCP) model to capture the components/drivers of national CP (macro level). Second, a Firm Competitive Productivity (FCP) model to capture the components/drivers of firm CP within an industry context (meso). And finally, an Individual Competitive Productivity (ICP) model capturing the components/drivers of CP at the individual (micro) level. Originality/value The study provides a combined approach to capture productivity and competitiveness within one innovative concept: CP. It can be used by government and policy makers (NCP model), managers and organisations (FCP model), and individuals such as workers and students (ICP model) to evaluate and enhance their performance. A better understanding of the components/drivers of CP at the three levels and the suggested measurement of CP should provide a stronger theory of competitiveness of nations, firms and individuals. Not least should a focus on the three levels (macro, meso and micro) better prepare citizens, firms, workers and students to effectively function and work in the marketplace and in society. The authors’ work should eventually contribute to more effective benchmarking and continuous improvement in the competitiveness domain. Crucially, this conceptual paper forms the foundation for future empirical testing of CP components in the context of the relative values and moderated behaviour as captured by the ReVaMB model.

Nationality decision making could impact immensely to country structural, society issues, and future population. Exploring the factors and model prediction could dramatical give benefits to Thailand-Japan or as a reference to other countries toward possibility of multiracial nationality decision making, policy approach to future population and international labor management. The case study of Thai-Japanese multiracial nationality decision making could crucial explain to 4 scenarioses under developing and developed country status contexts. The objectives in this exploratory basic factors research are (1) To study the possibility factors of multiracial decision making (2) To adjust the factors impact on multiracial decision making into a model prediction (3) To assess a model in separation of developing and developed country context toward multiracial decision making. This research conduted N=685 of multinaitonality Thai-Japanese in Bangkok (Thailand) under criteria control throught statistic processes requirement, questionnaire survey conducted in purposive sampling via online at Bangkok as the biggest majority province of Japanese migrant in Thailand (Thailand-Japan embassy,2019). PLS-SEM was considered to assess a formative measurement from lower to higher order and mediation model of macro, meso, and micro levels by using SMART-PLS 3.0. The results indicate that Thailand macro level should concern about “Political and governance”, and “Hospital and wellness” factors, Japan macro level should consider to “Economic”, and “Working environment” factors. Also, Thailand meso level have more issue on development factors than Japan, afterward meso factor as an individual background and experience reports that education and passport competency support to multiracial nationality decision making to both Thailand and Japan. As a result, Thailand macro, meso, and micro structure presents to the unrelevance between macro, meso, and micro which causes to unsupport of nationality decision making meanwhile Japan has a potential to escalate a policy toward macro and meso in better positive way with a significant support between macro, meso, and micro structure both direct and indirect to multiracial natonality decision making.

Full textAbstract:
Scholars in public administration now recognize three levels of analysis: macro, meso, and micro. But there is uncertainty about the relationship between levels and concern about a “schism” in research. However, linkages between levels can be demonstrated easily. At the macro-level, leaders develop an overall strategy for pursuing national priorities, which determines the broad architecture of the state. Institutions must be built, renovated, or managed to give effect to these strategies: This is the meso-level of public administration. Overall, strategies also shape the micro-level relationship between people who rule and people who are ruled. This is done by categorizing people—as subjects or citizens, for example—and by redefining categories. Macro-level strategies evolve, with consequences for the agenda at the meso- and micro-levels. Experience at lower levels also shapes strategy at the macro-level. The interaction among levels is illustrated by comparison of three eras in modern American history.

Purpose The purpose of this paper is to analyse how start-ups with a clear sustainability focus collaborate with multiple actors at different levels to pursue business ideas and develop sustainable freight transport solutions. Design/methodology/approach This paper builds on a theoretical approach that includes three levels of analysis: the actor level (micro), business-network level (meso) and society and government level (macro). An embedded case study is used of a focal start-up aiming to innovate on networked platforms and electric and autonomous vehicles (EAVs). Findings Activities and resources are developed at the firm (micro), network (meso) and societal levels (macro), and all three levels need to be considered for a start-up, with a clear sustainability focus. Interaction within as well as between levels affects the innovation development, integration and implementation. The many-folded collaborations at the meso level serve as a locus for the integration of EAVs. The start-up’s networking activities with actors at meso and macro levels contribute to it gaining legitimacy in the transport system. Originality/value This paper focuses on the importance of collaboration in the context of developing innovative solutions for environmental sustainability and freight transport and provides a unique case of how a start-up company manages collaborations at the micro, meso and macro levels.

Full textAbstract:
A micro-meso-macro analysis framework based on the multi-scale method was employed to analyse the mechanical behaviour of marine GFRP stiffened panels. The study aims to establish a procedure for assessing the impact of material composition and weave on the ultimate strength of GFRP stiffened panels. The ultimate strength assessment was an essential step in the design process, and the investigation of construction materials has a great benefit to the lightweight design of marine composite structures. The micro- and meso-scale RVE models of components used in GFRP materials are established, and their failure criteria and stiffness degradation models are created using the user-defined material subroutine VUMAT in ABAQUS. The equivalent material properties at the micro-scale (meso-scale) obtained by a homogenisation method are used to define the meso-scale (macro-scale) mechanical properties in the finite element analyses. The multi-scale method assesses the macro-mechanics of composites, and it is shown that the ultimate strength of GFRP stiffened panels is mainly determined by the failure of CSM fibre bundles and WR yarns. Parametric study of the meso-mechanics of composite materials can provide an analysis tool to obtain the optimal macro ultimate strength of the composite stiffened panel.

BackgroundEvidence from a national clinical audit of early inflammatory arthritis (EIA) shows considerable variability between hospitals in performance, unexplained by controlling for case-mix.ObjectiveTo explore the macro-level, meso-level and micro-level barriers and facilitators to the provision of good quality EIA care.MethodsA qualitative study within 16 purposively sampled rheumatology units across England and Wales. Quality was assessed in relation to 11 quality indicators based on clinical opinion, evidence and variability observed in the data. Data from semi-structured interviews with staff (1–5 from each unit, 56 in total) and an online questionnaire (n=14/16 units) were integrated and analysed using the framework method for thematic analysis using a combined inductive and deductive approach (underpinned by an evidence-based framework of healthcare team effectiveness), and constant comparison of data within and between units and its relationship with the quality criteria.FindingsQuality of care was influenced by an interplay between macro, meso and micro domains. The macro (eg, shared care arrangements and relationships with general practitioners) and meso (eg, managerial support and physical infrastructure) factors were found to act as crucial enablers of and barriers to higher quality service provision at the micro (team) level. These organisational factors directly influenced team structure and function, and thereby EIA care quality.ConclusionsVariability in quality of EIA care is associated with an interplay between macro, meso and micro service features. Tackling macro and meso barriers is likely to have a significant impact on quality of EIA service, and ultimately patient experience and outcomes.

Purpose This study aims to better understand the micro–meso–macro perspective in social marketing, through the examination of a transformative, primarily meso-level initiative aimed at developing more resilient communities in the face of disaster. Design/methodology/approach Research was oriented around two cases of community resilience planning. Relevant documents were reviewed, and a series of semi-structured interviews with the manager and advisors in an emergency management office were conducted, followed by in-depth interviews with 15 individual community participants. Findings The findings suggest a multilevel (micro–meso–macro) model of social change, incorporating fluid and interactive movement between the levels. In the context examined, community leaders were initially motivated to be involved due to their role, sense of altruism and curiosity. Their motivation to continue was encouraged, as misconceptions around emergency response were addressed and the value of community connections was highlighted. As planning progressed, greater involvement and empowerment resulted. Research limitations/implications This study is limited in its focus on two communities, and the context of emergency preparation and response. However, it contributes insights into a leading initiative designed to help build community resilience and insights into a micro–meso–macro perspective of social change. Practical implications The study also suggests that social marketers, when implementing a meso-level initiative, will benefit from considering multiple levels, seeking the involvement and cooperation of meso-level leaders which will help facilitate downstream change. Originality/value Contributing to the discussion of the micro–meso–macro levels of social marketing, this research examines disaster preparation and response – a context not frequently examined in social marketing. Findings suggest that interactive, multi-level thinking, especially considering the individual implementers of meso-level change as a “target market”, will benefit social well-being initiatives.

Productivity is a challenge in the construction industry, commonly initiated by fragmentation. In addition, some work levels have been identified, including the micro, meso, and macro. However, the construction supply chain is one of the possible solutions adopted to increase productivity. The purpose of this study, therefore, is to develop a framework for measuring supply chain construction performance at the micro, meso, and macro levels. These respective stages are tiered from the bottom to the top level as a supply chain management concept. Furthermore, a design for the supply chain performance measurement framework is created, followed by formulation with KPI, and the consequent application in the project. Therefore, performance is evaluated based on the construction materials, as a large resource. The results identified the supply chain performance at the micro-level as the basis for possible measures between contractor and supplier, using the SCOR. However, the emphasis was made on the strength of construction companies with large suppliers at the meso level. Meanwhile, the macro-level includes the accumulation of related measurements from micro as well as meso, and are consequently used to define the relationship between construction actors at the national level.

The construction industry is so fragmented that in its implementation many have resulted in increased costs, delays, and inefficiencies. But this fragmented can not be a reason not to innovate. One approach to the solution used is supply chain construction. The purpose of this study is to map supply chains micro, meso, and macro. This level is tiered from the bottom to the top level as the concept of supply chain management. The qualitative and quantitative research method was used to map and analyze supply chains for each level. The results showed the micro-level is the basis of the supply chain which can be measured by SCOR for example. The meso level focuses on the strength of construction companies. Construction company strategies framework contract and Enterprises Resource Planning (ERP). Macro-level includes supply chain accumulation from micro and meso. It is expected that at the macro level is the harmonization of supply chains between stakeholders, namely the government, contractors, suppliers, and distributors with good policy regulations.

Full textAbstract:
This study aims to understand the current state of research in urban resilience, its relations to urban sustainability and to integrate several distinct approaches into a multi-level perspective of cities comprising micro, meso and macro levels and their interactions. In fact, based on the meta-analysis of nearly 800 papers from Scopus from 1973 to 2018, we show that urban resilience discourses address micro and meso levels, considering shocks of bottom-up origin such as natural disasters. In contrast, the regional resilience approach addresses meso and macro levels (regional and global scales), considering shocks of top-down origin such as world economic crises. We find these approaches complementary and argue that in order to expand the urban resilience theory and overcome its limitations, they should be combined. For that purpose we propose a multi-level perspective that integrates both top-down and bottom-up dynamic processes. We argue that urban resilience is shaped by the synchronicity of adaptive cycles on three levels: micro, meso and macro. To build the multi-level approach of dynamics of adaptive cycles we use the panarchy framework.

By means of variational asymptotic homogenization, using Piola’s meso-macro ansatz, we derive the linear Timoshenko beam as the macro-scale limit of a meso-scale beam-like periodic planar square lattice structure. By considering benchmarks in statics and dynamics, meso-to-macro convergence is numerically analyzed. At the finest micro-scale, a 2D assembly of elastic, geometrically linear, isotropic and homogeneous Cauchy continua in plane strain with different material parameters is considered. Using this description, we calibrate the meso-scale model using standard methodology and, by exploiting the meso-to-macro homogenization scaling laws, we recover bending and shear Timoshenko beam moduli. It turns out that the Timoshenko beam found in this way and the finest-scale description based on the Cauchy continuum are in excellent agreement.

In part I, three-dimensional transient non-linear sub modeling heat transfer simulations were performed to study the thermal histories and thermal cycles that occur during the welding process at the macro, meso and micro scales. In the present work, the corresponding non-uniform temperature changes were imposed as load conditions on structural calculations to study the evolution of localized plastic strains and residual stresses at these sub-level scales. To reach the goal, a three-dimensional finite element elastic-plastic model (ABAQUS code) was developed. The sub-modeling technique proposed to be used in coupling phase-field (and/or digital microstructures) codes with finite element codes, was used to mesh a local part of the model with a refined mesh based on interpolation of the solution from an initial, relatively coarse, macro global model. The meso-sub-model is the global model for the subsequent micro sub-model. The strategy used to calculate temperatures, strains and residual stresses at the macro, meso and micro scale level, is very flexible to be used to any number of levels. The objective of this research was to initiate the development of microstructural models to identify fusion welding process parameters for preserving the single crystal nature of gas turbine blades during repair procedures. The multi-scale submodeling approach can be used to capture weld pool features at the macro-meso scale level, and micro residual stress and secondary dendrite arm spacing features at the micro scale level.

Introduction. In modern conditions, characterized by instability processes caused by the coronavirus disease pandemic 2019 (COVID-19), there is a need to establish warehousing logistics processes. Most large corporations and companies did not expect the closure of borders and factories, which led to further non-receipt of materials and their shortage. Therefore, in modern conditions, the study of the processes of development of warehousing logistics at the micro, meso and macro levels is gaining relevance. The aim of the article is to study the development of warehousing logistics at the micro, meso and macro levels. Results. It is determined that it is necessary to substantiate the levels of warehousing logistics because most scientists divide them into micro, meso, macro, mega and target. It is proved that it is expedient to divide the levels of warehouse logistics into three. It is determined that the first macro level belongs to the logistics operators of warehousing logistics (platform). At the second meso level of operation is due to logistics consulting. Services, departments, divisions of logistics of the enterprise provide the third micro level. Conclusions. It is proved that in modern conditions warehousing logistics is realized through independent creation, acquisition and management of LMS software or outsourcing of a third-party logistics company (3PL). Outsourcing will perform any logistics operations for you. It is determined that the use of 3PL gives a quick implementation period, without the need to train your employees in new processes, devices and software. Keywords: warehousing logistics, warehouse logistics management, warehousing logistics system, platforms, microlevel, mesolevel, macrolevel.

AbstractDespite their many contributions, each of the most prevalent approaches to leadership – the micro interpersonal leadership models such as transformational theory, trait theory and charismatic leadership, and the macro strategic management – has notable ‘blind spots’ and relies on biased or partial assumptions. Furthermore, the macro–micro polarization of major leadership theories overlooks important meso perspective processes, such as structuring, which leaders can use to attain a more compounded and sustained effect on organizational outcomes. The goal of this paper is to propose an integrative theoretical framework – value-creating leadership – which provides what is missing from the theory of organizational leadership. Value-creating leadership combines micro and macro perspectives regarding management and leadership along with a meso perspective to create a unified model of corporate leadership.

This article examines the effect of linguistic anxiety on identity by analyzing the use of English in Japanese television from the perspective of Sociocultural Linguistics. Close analysis of segments from Japanese television entertainment programs shows how both verbal and visual intertextual resources are used to create linguistic anxiety at the micro level of personal interaction, on the macro level of government policy and television genre, and also at meso levels that exist between both the macro and micro. Semiotic resources such as costumes, set design, subtitles, and other elements in the mediascape allow for circulation of ideologies from government policies into assessments of individuals. The role of meso level discourse in the bidirectional transmission of linguistic anxiety between the macro levels of society and the micro levels of personal interaction is discussed.

Modern mechano-mathematical models of materials are multilevel ones combining macro-, meso- and micro-level models. A major problem however is how to present a clear link between the levels. Moreover, structural models should be well verified, reflecting material behavior at meso-level and its microstructure. Hence, we propose a theoretical-experimental approach to multilevel modeling, treating discs which operate under plane stress. The approach comprises the following stages: I stage: Identify a system of characteristic points on the disc surface. Employing an appropriate optical method, find point displacements using time steps in the course of deformation. II stage: Based on displacement development in time, rationally find the variation of the strain tensor components using strains directed from the main point to the closest points of its vicinity. III stage: Define a meso-representative element in the disc plane as an ellipse with diameters related to the principal strains. IV stage: Having prepared metallographic micro-sections, define systems of characteristic structural elements in the meso-representative ellipses. V stage: Averaging the structural systems at meso-level, define macro-parameters involving material deformation parameters. VI stage: Find material macro-deformation parameters on the basis of an appropriate design of micro-representative elements and calculate the stressed-strained state of the latter applying representative loading.

Full textAbstract:
Dry fiber placement has a large potential for manufacturing preforms for primary-load components at minimum scrap rate and fiber crimp. Yet, challenging impregnation behavior due to low permeability of these preforms during liquid composite molding imposes a need for further research to optimize preform structure for higher permeability. For full understanding of flow behavior within these preforms, flow has to be considered on micro scale (in between single fibers), on meso scale (in between single rovings or strands), and on macro scale (on scale of parts to be manufactured). While macro and meso scale can be measured in experiments or derived from filling times in real processes, micro scale is usually not easily assessable and accessible for standard textile materials. Analytical approaches are limited to regular fiber arrangements (square and hexagonal) that are strongly differing from real arrangements. The present work deals with application of a numerical solver to random fiber arrangements to determine micro permeability transverse to the fiber orientation, for later use in meso- and macro-scaled models. As a premise for reliable calculation, guidelines for boundary conditions as well as size and resolution of the representative volume element are elaborated in the course of this work. Calculated out-of-plane micro permeabilities are subsequently compared to real experiments and show good accordance. The influence of binder particles on micro permeability has not yet been conclusively clarified.

A abordagem tradicional da economia industrial baseia-se em um modelo linear de produção, em que são extraídos insumos para a fabricação e a venda de mercadorias, as quais, após seu uso, são encaminhadas ao descarte (ELLEN MACARTHUR FOUNDATION, 2013). Nesse contexto a Economia Circular surge como um novo modelo econômico, o qual tem por diferencial a concepção do desenvolvimento econômico global como dissociado do consumo de recursos finitos (ELLEN MACARTHUR FOUNDATION, 2013). Com vistas a analisar os caminhos para a transição da economia linear para a circular, adota-se uma interpretação a partir de três escalas: Micro, Meso e Macro (ZENGWEI; JUN; YUICHI, 2019). Esse trabalho tem como objetivo compreender a abrangência das escalas Macro, Meso e Micro da Economia Circular e como essas três dimensões se interrelacionam em uma tentativa de transição rumo à circularidade. Essa pesquisa assume natureza aplicada (MARCONI, LAKATOS, 2012). Quanto aos seus objetivos, esta pesquisa revela uma visão exploratória e um caráter descritivo (FLEURY; 2017). As análises construídas nesse trabalho partem da utilização da técnica da pesquisa bibliográfica (Marconi, Lakatos; 2003), associada ao método Snowball (GOODMAN, 1961). Como resultado são apresentadas as descrições das três camadas de implementação da Economia Circular, Micro, Meso e Macro, bem como a forma como os níveis se interrelacionam.

PurposeThis paper aims to provide a more holistic perspective on rationales that motivated Maybank to move toward a sustainable banking operating system. Design/methodology/approachThe case study was based on primary data collected through a series of qualitative interview with 35 bankers who were from different departments. Besides, the secondary data such as academic books and journals, government and regulatory authority’s publications, website publications, Maybank’s annual reports and Maybank’s sustainability reports were reviewed to obtain a more comprehensive understanding on rationales that motivated Maybank to move toward a sustainable banking operating system. FindingsWithin the corporation studied, the rationales for moving Maybank toward sustainable banking operating system are driven by macro-, meso- and micro-level drivers. In terms of macro-level drivers, the pressures come from the bank’s external environment. A PESTLE analysis is used to discuss the drivers for change present within the macro environment. The different national government bodies and non-government organizations are calling upon financial institutions to implement more socially and environmentally friendly lending policies. In terms of meso-level drivers, stakeholders are viewed as important driving forces for Maybank to integrate sustainability into banking operations. Internal driving forces are likely to emanate from employees, the board of directors and shareholders. External driving forces result from pressure from customers, governments, competitors, NGOs and society at large. Micro-level drivers are drivers of sustainable banking that include pressures generated from within the bank’s internal environment. Maybank is largely motivated by its mission statement and vision statement, which is articulated in their sustainable banking agenda. Research limitations/implicationsViewing the rationales that motivated Maybank to move toward a sustainable banking operating system through multiple perspectives – macro-, meso- and micro-level drivers present an interesting approach for research. Originality/valueThe rationales for moving Maybank toward a sustainable banking operating system are driven by macro-, meso- and micro-level drivers. This paper provides fresh insight into rationales that move toward the sustainable banking operating system.

Full textAbstract:
This is the second of a two-paper series describing a multi-scale modeling approach developed to simulate crack sensing in polymer fibrous composites by exploiting interruption of electrically conductive carbon nanotube (CNT) networks. The approach is based on the finite element (FE) method. Numerical models at three different scales, namely the micro-scale, the meso-scale and the macro-scale, have been developed using the ANSYS APDL environment. In the present paper, the meso- and macro-scale analyses are described. In the meso-scale, a two-dimensional model of the CNT/polymer matrix reinforced by carbon fibers is used to develop a crack sensing methodology from a parametric study which relates the crack position and length with the reduction of current flow. In the meso-model, the effective electrical conductivity of the CNT/polymer computed from the micro-scale is used as input. In the macro-scale, the final implementation of the crack sensing methodology is performed on a CNT/polymer/carbon fiber composite volume using as input the electrical response of the cracked CNT/polymer derived at the micro-scale and the crack sensing methodology. Analyses have been performed for cracks of two different lengths. In both cases, the numerical model predicts with good accuracy both the length and position of the crack. These results highlight the prospect of conductive CNT networks to be used as a localized structural health monitoring technique.

Full textAbstract:
Microscopic characteristics greatly affect mechanical and physical properties as they exert vital impact on the stability and durability of materials. In this paper, widely distributed sandstone was chosen as the research object. Sandstone was treated with a coupled effect of Freeze–Thaw (F–T) weathering and acid solution, where freeze–thaw cycles were set as 0, 10, 20, 30 and 40 cycles, and the pH of the acid solution were set as 2.8, 4.2, 5.6 and 7.0, respectively. Then, nuclear magnetic resonance was applied to measure the microscopic characteristics of sandstone, then porosity, pore size distribution and permeability before the fractal dimensions were obtained and calculated. Results show that porosity increases when F–T cycles increase, and its increase grows with the pH of acid solution decrease during the first 10 F–T cycles. Macro porosity, meso porosity and micro porosity account for the largest, second largest and smallest ratio of porosity growth. Meso porosity, micro porosity and macro porosity account for the largest, second largest and smallest ratio of total porosity. Permeability increases obviously with F–T cycle increase, while acid erosion exerts little influence on permeability increment overall. Fractal dimensions of meso pores and macro pores increase with F–T cycle increase overall, and they increase with pH decrease overall. Porosity has strong exponentially correlation with permeability. Fractal dimensions of meso pores and macro pores have good linearly correlation with permeability, while correlation between porosity and fractal dimensions are not that obvious.

Threats caused by linear economy pushes humanity for transition to circular economy model. At macro level benefits of circular economy are seen very clearly, due to that, governments set priorities to reduce the environmental impact of economic growth and encourage businesses and consumers to implement circular economy principles. However, implementation of circular economy at micro level, by businesses and consumers, still appears to be in early stages. The purpose of this article is to create holistic view of barriers and drivers of circular economy, which would help to understand ways for encouraging business and consumer to use circular economy principles. For this purpose, 28 circular economy barriers and 22 circular economy drivers described in scientific literature was analysed. The result of the analysis - created system of circular economic barriers and drivers, which shows: directions for required macro level support to promote the transition of micro and meso level to circular economy model; way for benefits generated by micro and meso level, to achieve a macro level environment. The results of the research are theoretical and refer to the direction of further research.

The Scholarship of Teaching and Learning (SoTL) encompasses research on postsecondary teaching and learning across all disciplines. Why do scholars engage in the study of teaching and learning? What supports and challenges do they encounter? What is the impact of SoTL? Using a micro-meso-macro-mega (4M) framework, I explore these questions in interviews with seven SoTL scholars from various disciplines in one institution. Primarily, this article provides a case study illustration of the use of the micro-meso-macro-mega framework to explore SoTL. In addition to exploring participants’ reflections vis-à-vis the four levels, I reflect on possible connections to motivation theory as a lens for themes arising from the participants’ accounts of supports and barriers and the impact of their SoTL work.

Full textAbstract:
Although the literature on evaluation has theorized about the distinction between internal and external evaluation, hardly any research has compared them empirically. This article examines whether the lessons of internal evaluations differed from those of external evaluations in the case of international development aid. It analyzes internal evaluations of the Asian Development Bank for nearly 1000 sovereign interventions across 38 countries in the Asia-Pacific during 1996–2016, using computational text analysis or text mining techniques. The results show that internal evaluations focused more on micro- and meso-level characteristics, while external evaluations laid more emphasis on meso- and macro-level constructs, such as dimensions of policy and the institutional environment in the recipient country, or its level and rate of economic growth. The article concludes that internal and external evaluations can be combined to create a multilevel evaluation framework that integrates micro-, meso-, and macro-level lessons to facilitate better learning.

This paper studies the nature and the importance of the link between macro and micro levels of innovation management in the knowledge society of Denmark, Sweden, USA, India, Russia, and Moldova, suggesting that countries with different levels of knowledge society development have different link types between the macro and micro levels of innovation management. In particular, findings show that countries with a higher level of knowledge society development have a two-way mediation process between the micro and macro levels of innovation management while countries with lower level of knowledge society development tend towards a “one-direction” link. This paper argues that innovation management can only be fully effective through paying attention to this intersection, which is free of biases inherent in each individually. The authors conclude by introducing a “meso-level” indicator for knowledge society development and underline areas of further research in the field.

Full textAbstract:
Sustainability leadership aims at balancing short-term economic goals with long-term sustainable development goals by considering the interests of all stakeholders instead of just shareholders and focusing on a triple bottom line: people, planet, and profit. The existing research on sustainability leadership has mainly focused on the role of individual competencies without considering other meso and macro level factors that can impact the enactment of sustainable leadership. The studies that have considered these micro, meso, and macro levels have conceptualized these levels as stratified and discrete, assuming a hierarchical relationship between them. Such a conceptualization constitutes an impediment to the dynamic communication and engagement that is necessary to the achievement of sustainability goals. Drawing on stakeholder theory, this study investigates the key factors impacting the practice of sustainability leadership in a contextually relevant manner. More specially, we propose a multi-level, multi-stakeholder framework for sustainability leadership that is data driven and supported by evidence. This framework is meant to portray a holistic model that is dynamic and reciprocal in the manner in which micro, meso and macro factors impact each other. Qualitative research methods and purposive sampling were used for four stages of data collection, from 39 individuals with diverse profiles across the sustainable-engineering sector. The data collected were analyzed thematically, and the findings formed the basis of the dynamic inclusive business model for sustainability proposed in this paper, which challenges the traditional hierarchical business models. The data-driven, multi-level, multi-stakeholder framework proposed in this work extends the literature by providing insights on the key factors that impact the practice of sustainability leadership in the context of SMEs, operating in an emerging market. This framework demonstrates that the effective practice of sustainability leadership by SMEs is influenced by the interplay of factors at micro, meso and macro levels, as represented by individuals, organizations/firms, and governments.

Full textAbstract:
This paper reported the tensile failure strengths and damage procedure of composite laminate manufactured from the toughened-epoxy T800 prepreg at multi-scale levels. According to the exterior and interior distinction of each layer in laminate, the macro/mesoscale representative volume element (macro-RVE, meso-RVE) was first constructed, respectively. Then the micro-scale representative volume element (micro-RVE) with a hexagonal fiber-packed pattern in the interior zone of each layer in the laminate was finally determined on the principle of the same fiber volume fraction between the composite laminate and multi-scale RVEs. In the multi-RVEs analysis, the mechanical failure strengths of each scale model were transmitted from the last-scale model’s homogenization, such as the meso-RVE from micro-RVE and the macro-RVE from meso-RVE. Based on our previous report, the innovative multi-scale damage and post-damage models on the concept of the smear crack were improved fully and incorporated by user-defined material subroutines (UMATs), such as in the addition of multiple cracks co-coupled, which makes it predict the element damage procedure. The averaged mechanical responses with damage mechanism of multi-scale RVEs under tensile, compressive, or shear loadings were obtained wholly by the homogenization method. The macroscale tensile damage initiation and propagation procedure were analyzed in detail including their global/local responses, being extended to comparison with experimental results.

Full textAbstract:
Soil enzymes strongly affect soil organic carbon (SOC) and nitrogen (TN) storage. However, few studies have focused on their relationships in aggregates, especially in sodic-alkali agricultural fields. In the current study, we hypothesized that the impact of soil enzymes on SOC and TN were different within aggregates for their heterogeneous distribution. Soils collected from the surface (0–20 cm) and subsurface (20–40 cm) layers of sodic-alkali agricultural fields in the northeast of China were separated via the dry sieve method into macro-aggregates (>2000 μm), meso-aggregates (250–2000 μm), and micro-aggregates (<250 μm). SOC, TN, microbial biomass carbon (MBC) and nitrogen (MBN), and C- and N-cycling enzymes, namely amylase (AMY), invertase (INV), β-glucosidase (GLU), catalase (CAT), β-N-acetylglucosaminidase (NAG), and urease (URE) in soil aggregates were tested and analyzed. High content of SOC and TN were observed in macro- and meso-aggregates in both layers, with the largest amount detected in meso-aggregates. The highest values of MBC and MBN were observed in meso-aggregates, followed by micro-aggregates for MBC and macro-aggregates for MBN. Soil enzymes were distributed heterogeneously in soil aggregates, where the activities of AMY, INV, and URE in both layers were in the order of meso-aggregates > macro-aggregates > micro-aggregates. The same trend was followed by NAG of surface soils, while in the subsurface soils, NAG activities increased with the increasing aggregate sizes. NAG activities in both layers decreased with decreasing aggregate sizes. The GLU activity rose with the decreasing aggregate sizes in both layers, contrary to CAT. Enzyme activities affect SOC and TN in soil aggregates, for NAG, INV, GLU, and URE are closely related to SOC and TN across aggregate sizes. The test indices mentioned above in the surface layer were higher than those in the subsurface layer. These results indicate that biophysical processes associated with C- and N-cycling enzymes may be vital to the SOC and TN sequestration within soil aggregates in sodic-alkali agricultural fields.
