Advertisement policy for dual-channel within emissions-controlled flexible production system

Nowadays, industrial firms are very much careful to build a green environment by reducing carbon emissions. The government imposes some rules and regulations to provide a better eco-friendly environment. In this study, the cap-and-trade mechanism has been considered in a production model to control the carbon emissions rate. The manufacturers invest in advanced green technology to reduce per unit emissions. As online and offline selling is crucial to any industry for increasing customer demand, the manufacturers sell their products by dual-channel and advertise their products by online channel to make more popular of their products. Keeping these in mind, a sustainable flexible production model with single-type substitutable product production is considered here by imposing a cap-and-tax policy, investing in green technology, and advertising for products. This model is divided into two cases: with and without investment in green technology. The demand of each manufacturer depends upon an online selling price, an offline selling price, and an online advertisement of the product. A classical optimization technique helps to get the optimum strategies for the online selling price, offline selling price, advertisement investment, green technology, cycle time, and production rate. From the numerical study, it is proved that the industry gets 6.97% more profit in the case of green technology investment and the proposed study gives 5.74% more profit than the traditional production system. Sensitivity analysis and managerial insights are performed.     

How do customers meet their needs in in-store and online fashion shopping? A comparative study based on the jobs-to-be-done theory

Understanding customer needs is key for fashion retailers to stay competitive and innovative. Surprisingly, however, extant literature mainly explores customer needs in terms of a garment and its attributes rather than viewing shopping as a problem-solving process to meet customer needs. Moreover, these studies fail to address how customers meet their needs in-store (ISFR) and online fashion retailing (OFR). To fill this research gap, we empirically investigate customers' personal and social needs and how they can be met through the jobs-to-be-done theory. Findings reveal that, beyond the purchase of a garment, customer needs can be fulfilled through different ways, such as smart technology or a person's high interaction with social others in ISFR and the online shop experience or a social linkage without social interaction in OFR. Additionally, our findings offer potential service innovations for fashion retailing managers.     

Beyond radical affordability in the base of the pyramid: The role of consumer self-confidence in product acceptance

When developing products and services for base of the economic pyramid (BoP) consumers, it has been widely assumed that organizations must set extremely low prices that are dependent on substantial product acceptance and economies of scale. However, such pricing is often not feasible. Growing evidence suggests that more moderate price levels are needed for organizations to viably serve the needs of low-income consumers. However, price sensitivity is less understood in low-income contexts. To promote the success of social enterprises through fresh insight, we reexamine the extremely low-price BoP assumption by investigating product acceptance among low-income consumers using two experiments in Latin America. Results reveal that a belief in one's capabilities to make effective consumption decisions, consumer self-confidence, helps explain the acceptance of moderately-priced products. Discussion highlights directions for stimulating acceptance of socially beneficial products in low-income contexts.     

Life after school: How science and technology teachers construe capability

Science and technology teachers create microcosms of the world beyond school as responses to perceived student needs. The focus of these microcosms for both science and technology classrooms was less of a concern for work preparation than for the development of social and intellectual habits. All of the teachers have strong views of the virtues of civil daily life and what it might take for their students to live the good life. The practical capability the teachers want their students to have transcends the instrumental to become moral.

干旱区绿洲生态农业现代化模式研究

西北地区是我国典型的干旱区,水资源匮乏、生态脆弱和气候干燥等因素是干旱区的主要特征,在该区农业现代化的进程中这些特点是不容忽视的。文章从农业现代化模式含义的理解入手,通过对国内外先进农业模式的研究,借鉴其在发展过程中的经验与教训,总结出适合西北干旱区绿洲生态农业发展的现代化模式,并将模式定位于滴灌大田精准农业现代化模式、滴灌设施农业模式、滴灌特色林果(药)复合农业模式与现代农业示范园区模式。     

数字经济产业集聚对绿色技术创新的影响 ——基于环境规制的调节效应分析

绿色转型是推动高质量发展的重要组成部分,实现绿色转型的关键在于绿色技术创新,但学界尚未从数字经济产业集聚视角展开分析。基于我国30省市（因数据缺失,不含西藏地区及港澳台地区）2013—2020年面板数据,分析数字经济产业集聚对绿色技术创新的影响及其调节机制。研究发现：数字经济产业、数字经济制造业和数字经济服务业集聚对绿色技术创新的影响呈“倒U型”,均通过了1%水平的显著性检验,影响程度依次减小且存在滞后性,表明数字经济产业协同集聚对绿色技术创新的影响效应更强。通过计算拐点值发现,多数中西部省市处在“倒U型”的左侧,部分东部省市已经超过拐点值。引入环境规制调节变量后,发现其能够强化数字经济产业和数字经济制造业集聚对绿色技术创新的“倒U型”影响,且滞后性明显。本文为我国各省市加快经济发展方式绿色转型提供政策启示,也为提高区域绿色技术创新能力提供现实参考。     

The Determinants Of The Adoption Of Advanced Manufacturing Technology

The paper investigates empirically the decision of firms to adopt ‘Advanced Manufacturing Technologies’ (AMT) based on a comprehensive specification of a ‘rank model’ of technology adoption using firm-level data for Swiss manufacturing. The explanatory variables include numerous dimensions of (anticipated) benefits from and costs of technology adoption allowing for uncertainty as well as for information and adjustment costs. Moreover, the effect of complementarities between various functional groups of AMT (design, fabrication, communication, etc.) as well as of learning from the use of previous technology vintages within such functional groups is analyzed, Finally, the size-dependence of the adoption decision is studied in detail. The model yields a quite robust pattern of explanation across estimates with different adoption variables (time period of introduction of AMT, intensity of use of AMT, etc.) with plausible differences of the results based on the alternative adoption measures used.
