Time to seize the digital evolution: Adoption of blockchain in operations and supply chain management among Malaysian SMEs

This study aims to investigate the effects of relative advantage, complexity, upper management support, cost, market dynamics, competitive pressure and regulatory support on blockchain adoption for operations and supply chain management among Small-Medium Enterprises (SMEs) in Malaysia. Unlike existing studies that employed linear models with Technology Acceptance Model or United Theory of Acceptance and Use of Technology that ignores the organisational and environmental factors, we adopted the Technology, Organisation and Environment Framework that covers the technological dimensions of relative advantage and complexity, organisational dimensions of upper management support and cost and environmental dimensions of market dynamics, competitive pressure and regulatory support. Empirical data from 194 SMEs were investigated and ranked using a nonlinear non-compensatory PLS-ANN approach. Competitive pressure, complexity, cost and relative have significant effects on behavioural intention. Market dynamics, regulatory support and upper management support were insignificant predictors. SMEs often lack resources for technological investments but faces same requirements for streamlining business processes to optimise returns and blockchain presents a viable option for SMEs’ sustainability due to its features of immutability, transparency and security that have the potential to revolutionise businesses. This study contributes new knowledge to the literature on factors that affect blockchain adoption and justifications were discussed accordingly.     

中国小麦的耕地竞争及其对小麦供求平衡的影响

本文对我国小麦主产区与小麦具有耕地竞争关系的不同农作物之间的成本收益进行了比较,发现我国小麦主产区中黄淮海麦区的河南、山东两省小麦种植面积下降,但优质专用小麦播种面积扩大,长江中下游麦区中的湖北、四川和东北麦区中的黑龙江小麦播种面积也出现不同程度的下降.研究结果说明,在耕地资源有限并且不断减少的情况下,由于各主产区的小麦成本收益率较低,部分地区的小麦品质较差,小麦的耕地竞争优势下降,从而导致小麦种植面积持续下降,小麦产量不断减少.但优质专用小麦的品质和生产效益较好,我国优质专用小麦的种植面积和产量大幅度提高.同时,产量下降会直接影响我国小麦市场的供求平衡,通过对建立的中国小麦供求平衡表分析,如果我国小麦种植面积继续减少,今后2年～3年内我国小麦供求格局将会发生逆转,国内小麦供给总量不能满足国内需求的情况,将对我国小麦的国际贸易产生重大影响.

The impact of IT on supply chain agility and firm performance: An empirical investigation

This study investigates the impact of information technology (IT) on supply chain agility measured by the ability to sense and respond to market changes, and the impact supply chain agility has on firm performance. Data were collected from supply chain executives at 193 U.S. manufacturing firms. The results suggest that IT improves the supply chain's ability to sense market changes by improving the adequacy, accuracy, accessibility, and timeliness of the information flows among members of the supply chain. IT also increases the supply chain's ability to respond to market changes by reducing the cost, and improving the quality and timeliness of developing and executing coordinated plans to respond to market changes throughout the supply chain. Importantly, the results indicate that enhanced supply chain agility has positive impacts on the firm's sales, market share, profitability, speed to market, and customer satisfaction.

农民进城：城市准备好了吗

从上世纪80年代发展小城镇到本世纪走向大中城市的规模扩张和加速建设,我国已进入大中小城市全面多层次发展的城市化加速期。城市为农民进城供给了大量的公共物品和制度空间。然而,城市在接迎农民进城中仍然存在着多方面的矛盾和问题。随着农民进城,城市社会孕育产生了“不可忽视的”新社会力量与社会关系新矛盾,面临着多阶层多方面利益主体以及多样性多层面文化的社会整合问题。在当前,做好“农民进城”这项大工程,主要是促进农民充分就业,以进城农民为本,深化改革,建设城市美好家园。     

Evaluating student allocation in the Portuguese public higher education system

This paper characterizes and evaluates the student allocation in the Portuguese public higher education system. It describes the supply and demand sides of the system by looking at the numerus clausus across areas of study and institutions, institutions’ degree of diversity, and performance and adjustment indicators based on students’ revealed preferences. Performance indicators quantify the adequacy between demand and supply, across institutions and fields of study, and gauge the performance of public higher education institutions in the competition for candidates. Adjustment indicators allow us to predict the potential impact of changes in higher education regulations on student allocation and its stability. According to these indicators, such changes could result in an expansion for some institutions and fields of study, whereas other institutions might face a reduction.
