Contemporary literature reveals that, to date, the poultry livestock sector has not received sufficient research attention. This particular industry suffers from unstructured supply chain practices, lack of awareness of the implications of the sustainability concept and failure to recycle poultry wastes. The current research thus attempts to develop an integrated supply chain model in the context of poultry industry in Bangladesh. The study considers both sustainability and supply chain issues in order to incorporate them in the poultry supply chain. By placing the forward and reverse supply chains in a single framework, existing problems can be resolved to gain economic, social and environmental benefits, which will be more sustainable than the present practices.

The theoretical underpinning of this research is ‘sustainability’ and the ‘supply chain processes’ in order to examine possible improvements in the poultry production process along with waste management. The research adopts the positivist paradigm and ‘design science’ methods with the support of system dynamics (SD) and the case study methods. Initially, a mental model is developed followed by the causal loop diagram based on in-depth interviews, focus group discussions and observation techniques. The causal model helps to understand the linkages between the associated variables for each issue. Finally, the causal loop diagram is transformed into a stock and flow (quantitative) model, which is a prerequisite for SD-based simulation modelling. A decision support system (DSS) is then developed to analyse the complex decision-making process along the supply chains.

The findings reveal that integration of the supply chain can bring economic, social and environmental sustainability along with a structured production process. It is also observed that the poultry industry can apply the model outcomes in the real-life practices with minor adjustments. This present research has both theoretical and practical implications. The proposed model’s unique characteristics in mitigating the existing problems are supported by the sustainability and supply chain theories. As for practical implications, the poultry industry in Bangladesh can follow the proposed supply chain structure (as par the research model) and test various policies via simulation prior to its application. Positive outcomes of the simulation study may provide enough confidence to implement the desired changes within the industry and their supply chain networks.

Up until recent years, all agricultural production in Norway was strictly regulated through spatial policy (location), production quotas and other price and market regulations. Prices and products were handled by the farmers’ cooperatives. International (e.g. WTO agreements) and domestic pressure has gradually loosened the governmental regulation of chicken and eggs. Economic (e.g. new ownerships), technological (innovations throughout the whole chain), political and institutional (liberalization) and cultural (e.g. in consumption and farming) changes have reconfigured the landscapes of chicken meat production, opening up new opportunities for the chicken industry. Chicken therefore makes a particularly good case for exploring recent major changes in the agri-food system. In this chapter, we investigate evolving rules, risks, challenges and opportunities in and around chicken meat value chains. Empirically, we build on interviews, document studies and statistics on the structural development of the chicken industry and we discuss how these changes are developing in other parts of the Norwegian agri-food system.

Purpose – The purpose of this study is to share empirical research with educators and researchers to show how the gradual release of responsibility (GRR) model can support bilingual teachers’ implementation of dialogic reading comprehension instruction in student-led small groups and linguistically responsive literacy instruction with emergent bilingual students (Spanish–English) in grades one through four.

Design/Methodology/Approach – The authors provide brief literature reviews on the literacy instruction that bilingual students in low-resourced schools typically receive, on dialogic reading comprehension instruction, and on linguistically responsive literacy instruction. Then, the authors show how teacher educators utilized the GRR framework and process to support bilingual teachers’ movement from whole-class, teacher-directed instruction to dialogic reading comprehension instruction in student-led small groups. Next, the authors illustrate how a third-grade dual-language teacher employed the GRR to teach her students how to use Spanish–English cognates. Lastly, the authors share three vignettes from a first-grade bilingual teacher’s use of the GRR to facilitate her students’ comprehension of teacher read-alouds of narrative and informational texts and English writing.

Findings – When the teacher educators employed the GRR model in combination with socio-constructivist professional staff development, the teachers revealed their concerns about small-group instruction. The teacher educators adjusted their instruction and support to address the teachers’ concerns, helping them to implement small-group instruction. The third-grade bilingual teacher employed the GRR to teach her students how to use a translanguaging strategy, cognates, when writing, spelling, and reading. The first-grade bilingual teacher’s use of the GRR during teacher read-alouds in Spanish and English provided space for her and her students’ translanguaging, and facilitated the students’ comprehension of narrative and informational texts and completion of an English writing assignment.

Research Limitations/Implications – The findings were brief vignettes of effective instruction in bilingual settings that employed the GRR model. Although the authors discussed the limitations of scripted instruction, they did not test it. Additional research needs to investigate how other teacher educators and teachers use the GRR model to develop and implement instructional innovations that tap into the unique language practices of bilingual students.

Practical Implications – The empirical examples should help other teacher educators and bilingual teachers to implement the GRR model to support the improved literacy instruction of bilingual students in grades one through four. The chapter defines linguistically responsive instruction, and shows how translanguaging can be used by bilingual teachers and students to improve the students’ literacy performance.

Originality/Value of Chapter – This chapter provides significant research-based examples of the use of the GRR model with bilingual teachers and students at the elementary level. It shows how employment of the model can provide bilingual teachers and students with the support needed to implement instructional literacy innovations and linguistically responsive instruction.

This chapter does three things. First, it estimates regional gross domestic product (GDP) for three different geographical levels in Switzerland (97 micro regions, 16 labor market basins, and 3 large regions). Second, it analyzes the evolution of regional inequality relying on a heuristic model inspired by Williamson (1965), which features an initial growth impulse in one or several core regions and subsequent diffusion. Third, it uses index number theory to decompose regional inequality into three different effects: sectoral structure, productivity, and comparative advantage.

The results can be summarized as follows: As a consequence of the existence of multiple core regions, Swiss regional inequality has been comparatively low at higher geographical levels. Spatial diffusion of economic growth occurred across different parts of the country and within different labor market regions. This resulted in a bell-shaped evolution of regional inequality at the micro regional level and convergence at higher geographical levels. In early and in late stages of the development process, productivity differentials were the main drivers of inequality, whereas economic structure was determinant between 1888 and 1941. The poorest regions suffered from comparative disadvantage, that is, they were specialized in the vary sector (agriculture), where their relative productivity was comparatively lowest.

Given the growing interest in social movements as policy agenda setters, this paper investigates the contexts within which movement groups and actors work with political elites to promote their common goals for policy change. In asking how and why so-called outsiders gain access to elites and to the policymaking process, I address several contemporary theoretical and empirical concerns associated with policy change as a social movement goal. I examine the claim that movements use a multipronged, long-term strategy by working with and targeting policymakers and political institutions on the one hand, while shaping public preferences – hearts and minds – on the other; that these efforts are not mutually exclusive. In addition, I look at how social movement organizations and actors are critical in expanding issue conflict outside narrow policy networks, often encouraged to do so by political elites with similar policy objectives. And, I discuss actors’ mobility in transitioning from institutional activists to movement and organizational leaders, and even to protesters, and vice versa. The interchangeability of roles among actors promoting social change in strategic action fields points to the porous and fluid boundaries between state and nonstate actors and organizations.

In the Bollywood film Crow's Egg (Manikandan, 2015), two Indian children eat crow eggs that they collect from trees (taking three out of four eggs and leaving one with the mother crow) because they cannot afford chicken eggs. Because their father is in prison, the children make money by selling pieces of coal that fall off trains to support their working mother. Interestingly, the film shows no images of school in the lives of the two children, aged about seven and 10, and their friends next to them. Unfortunately, there are millions of children in the world who have no room for school in their lives, and they are not just numbers, they are individuals.

The endpoint and hallmark of the success of intercultural teaching is often seen as the attainment of intercultural competence. Yet, there is a need for a detailed examination of some of the enduring personal and professional identity and culture aspects of cross-cultural teaching. In this chapter, I deliberate over the application of narrative inquiry tools for unpacking teachers' experiences of immersion in a foreign country and culture of schooling. I reflect on my own experiences as a teacher in Japan and draw on an inquiry into the experiences of novice Canadian teachers in Hong Kong or Japan to shed light on fluid conceptions of culture shock and reverse culture shock in terms of cultural identity transformations. I also raise to the forefront inquiry puzzles about the phenomenon of intercultural competence acquisition.
