Supplier Strategies and Routines for Capability Development: Implications for Upgrading
\ua9 2018 The Authors. This paper examines the strategies and routines adopted by small and medium-sized suppliers to develop capabilities that enable them to engage in upgrading, despite a precarious relational and institutional context. To this end, we investigate the strategic behaviour of two Bangladeshi garment manufacturers. Both started out as small suppliers for multinational enterprises (MNEs) and have eventually grown into micro-multinationals. The firms are involved in âtacit promissory contractingâ with their buyers, a specific form of international outsourcing relationship. The study adopts a multiple case study design that involves interviews with managers/owners of the firms. The analysis yields two key findings. Both firms have devised strategies and taken coherent routines involving actions to develop skills and motivation needed to perform appropriate functional activities (i.e. pre-production, production and post-production) as they embarked on different stages of upgrading. Furthermore, firms have designed routines to internalise the challenges originating from their relationships with their buyers and the institutional environment at the time that had the potential to affect their upgrading goals. The paper contributes to IB studies by highlighting how suppliers, even in a precarious context, can control their own strategies and routines, so as to develop capabilities that allow them to gradually redress the power imbalance between themselves and their buyers
Rana Plaza collapse aftermath: Are CSR compliance and auditing pressures effective?
Purpose: The paper sets out to investigate the intended and unintended consequences of compliance and auditing pressures in the Bangladeshi garment industry. To explore this issue we draw on three medium sized suppliers. The institutional changes that followed the Rana Plaza accident in April 2013 make Bangladesh in general and the garment industry in particular an interesting and suitable research setting for standards compliance. // Design: The study adopts a multiple case study approach. Face-to-face interviews have been conducted with the owners of three Bangladeshi garment manufacturing firms and several workers. Additionally, organisational documents and local newspaper articles had been collected wherever possible. // Findings: The results indicate that the pressure for compliance has led the case companies to prioritise the implementation of measurable standards over the socially grounded needs and priorities of workers. As a consequence certain initiatives instead of adding new social value in fact destroyed previously existing social value. Furthermore, the pressure for compliance created the necessity to find ways to cover the sizable cost of compliance. This prompted firms to pursue process upgrading through technological advancements and increased work pressures on the labour force. These initiatives led to an increased power imbalance and the exclusion of unskilled workers from the job market.// Originality: The paper contributes to the understanding of the human rights implications of compliance and auditing pressures and initiatives. Furthermore, in order to further enrich existing knowledge in the critical accounting literature, the study draws on insights from the global value chains (GVC) and international business (IB) literatures
A reconceptualization of social value creation as social constraint alleviation
Purpose â This paper has two interconnected objectives. The first is to provide a reconceptualisation of social value creation as social constraint alleviation. The second is to respond to the call put forward by Giuliani and Macchi (2014) to produce synergies between bodies of literature exploring the development impact of businesses. The paper focuses on ideas from the global value chain/global production networks (GVC/GPN), business and human rights, corporate social responsibility (CSR), international business (IB) and (social) entrepreneurship literatures. Design/methodology/approach â The paper offers a reconceptualisation of social value creation by building on the synergies, complementarities, and limitations of existing concepts identified through the literature review. Findings â The reconceptualisation of social value creation put forward in this paper contributes to the literature in the following way. It offers a useful and clear definition of the term âsocialâ (cf. Devinney, 2009), and it attends to the limitations of the constraint concept as put forward by Ted London and his collaborators (eg. London, 2011). Furthermore, it sketches out the basic ideas of a two-system approach to allow for the differentiation between symptom treatment and root cause alleviation. Finally, it offers a refinement of Wettsteinâs (2012) proposed capability-based remedial action concept. The paper furthermore proposes that there are three distinct ways in which businesses generally respond to social constraints. Originality/value â The paper illustrates how the redefined concept of social value creation can connect different bodies of literature and help make sense of existing empirical results, without engaging in definitional debates
Genetic properties of feed efficiency parameters in meat-type chickens
<p>Abstract</p> <p>Background</p> <p>Feed cost constitutes about 70% of the cost of raising broilers, but the efficiency of feed utilization has not kept up the growth potential of today's broilers. Improvement in feed efficiency would reduce the amount of feed required for growth, the production cost and the amount of nitrogenous waste. We studied residual feed intake (RFI) and feed conversion ratio (FCR) over two age periods to delineate their genetic inter-relationships.</p> <p>Methods</p> <p>We used an animal model combined with Gibb sampling to estimate genetic parameters in a pedigreed random mating broiler control population.</p> <p>Results</p> <p>Heritability of RFI and FCR was 0.42-0.45. Thus selection on RFI was expected to improve feed efficiency and subsequently reduce feed intake (FI). Whereas the genetic correlation between RFI and body weight gain (BWG) at days 28-35 was moderately positive, it was negligible at days 35-42. Therefore, the timing of selection for RFI will influence the expected response. Selection for improved RFI at days 28-35 will reduce FI, but also increase growth rate. However, selection for improved RFI at days 35-42 will reduce FI without any significant change in growth rate. The nature of the pleiotropic relationship between RFI and FCR may be dependent on age, and consequently the molecular factors that govern RFI and FCR may also depend on stage of development, or on the nature of resource allocation of FI above maintenance directed towards protein accretion and fat deposition. The insignificant genetic correlation between RFI and BWG at days 35-42 demonstrates the independence of RFI on the level of production, thereby making it possible to study the molecular, physiological and nutrient digestibility mechanisms underlying RFI without the confounding effects of growth. The heritability estimate of FCR was 0.49 and 0.41 for days 28-35 and days 35-42, respectively.</p> <p>Conclusion</p> <p>Selection for FCR will improve efficiency of feed utilization but because of the genetic dependence of FCR and its components, selection based on FCR will reduce FI and increase growth rate. However, the correlated responses in both FI and BWG cannot be predicted accurately because of the inherent problem of FCR being a ratio trait.</p
Blue carbon stock of the Bangladesh Sundarban mangroves: what could be the scenario after a century?
The total blue carbon stock of the Bangladesh Sundarban mangroves was evaluated and the probable future status after a century was predicted based on the recent trend of changes in the last 30 years and implementing a hybrid model of Markov Chain and Cellular automata. At present 36.24 Tg C and 54.95 Tg C are stored in the above-ground and below-ground compartments respectively resulting in total blue carbon stock of 91.19 Tg C. According to the prediction 15.88 Tg C would be lost from this region by the year 2115. The low saline species composition classes dominated mainly by Heritiera spp. accounts for the major portion of the carbon sock at present (45.60 Tg C), while the highly saline regions stores only 14.90 Tg C. The prediction shows that after a hundred years almost 22.42 Tg C would be lost from the low saline regions accompanied by an increase of 8.20 Tg C in the high saline regions dominated mainly by Excoecaria sp. and Avicennia spp. The net carbon loss would be due to both mangrove area loss (~ 510 km2) and change in species composition leading to 58.28 Tg of potential CO2 emission within the year 2115
Identification of candidate tumour suppressor genes frequently methylated in renal cell carcinoma
Promoter region hyermethylation and transcriptional silencing is a frequent cause of tumour suppressor gene (TSG) inactivation in many types of human cancers. Functional epigenetic studies, in which gene expression is induced by treatment with demethylating agents, may identify novel genes with tumour-specific methylation. We used high-density gene expression microarrays in a functional epigenetic study of 11 renal cell carcinoma (RCC) cell lines. Twenty-eight genes were then selected for analysis of promoter methylation status in cell lines and primary RCC. Eight genes (BNC1, PDLIM4, RPRM, CST6, SFRP1, GREM1, COL14A1 and COL15A1) showed frequent (30% of RCC tested) tumour-specific promoter region methylation. Hypermethylation was associated with transcriptional silencing. Re-expression of BNC1, CST6, RPRM and SFRP1 suppressed the growth of RCC cell lines and RNA interference knock-down of BNC1, SFRP1 and COL14A1 increased the growth of RCC cell lines. Methylation of BNC1 or COL14A1 was associated with a poorer prognosis independent of tumour size, stage or grade. The identification of these epigenetically inactivated candidate RCC TSGs can provide insights into renal tumourigenesis and a basis for developing novel therapies and biomarkers for prognosis and detection. © 2010 Macmillan Publishers Limited.Published versio
Blue Carbon Stock of the Bangladesh Sundarban Mangroves: What could Be the Scenario after a Century?
Demand for Zn2+ in Acid-Secreting Gastric Mucosa and Its Requirement for Intracellular Ca2+
Recent work has suggested that Zn(2+) plays a critical role in regulating acidity within the secretory compartments of isolated gastric glands. Here, we investigate the content, distribution and demand for Zn(2+) in gastric mucosa under baseline conditions and its regulation during secretory stimulation.Content and distribution of zinc were evaluated in sections of whole gastric mucosa using X-ray fluorescence microscopy. Significant stores of Zn(2+) were identified in neural elements of the muscularis, glandular areas enriched in parietal cells, and apical regions of the surface epithelium. In in vivo studies, extraction of the low abundance isotope, (70)Zn(2+), from the circulation was demonstrated in samples of mucosal tissue 24 hours or 72 hours after infusion (250 ”g/kg). In in vitro studies, uptake of (70)Zn(2+) from media was demonstrated in isolated rabbit gastric glands following exposure to concentrations as low as 10 nM. In additional studies, demand of individual gastric parietal cells for Zn(2+) was monitored using the fluorescent zinc reporter, fluozin-3, by measuring increases in free intracellular concentrations of Zn(2+) {[Zn(2+)](i)} during exposure to standard extracellular concentrations of Zn(2+) (10 ”M) for standard intervals of time. Under resting conditions, demand for extracellular Zn(2+) increased with exposure to secretagogues (forskolin, carbachol/histamine) and under conditions associated with increased intracellular Ca(2+) {[Ca(2+)](i)}. Uptake of Zn(2+) was abolished following removal of extracellular Ca(2+) or depletion of intracellular Ca(2+) stores, suggesting that demand for extracellular Zn(2+) increases and depends on influx of extracellular Ca(2+).This study is the first to characterize the content and distribution of Zn(2+) in an organ of the gastrointestinal tract. Our findings offer the novel interpretation, that Ca(2+) integrates basolateral demand for Zn(2+) with stimulation of secretion of HCl into the lumen of the gastric gland. Similar connections may be detectable in other secretory cells and tissues
