不同储藏条件对稻米蒸煮品质和α-淀粉酶的影响

以稻谷粤农丝苗为原材料,置于4种不同储藏模式下,具体如下:(1)15℃储藏240d。(2)30℃储藏240d。(3)以15℃为开端,与30℃交替储藏(60d交替1次)至240d。(4)以30℃为开端,与15℃交替储藏(60d交替1次)至240d。每隔60d检测1次,比较上述4种储藏模式下,稻米蒸煮品质和α-淀粉酶活力的变化趋势。研究结果表明:随着时间的延长和储藏温度的升高,稻米品质下降;在实验时间内,以低温为开端的变温模式的稻米品质要优于以高温为开端的变温模式,但差距逐渐减小。     

改造我们的教学

进入"双高时代",我们距离新时代高等职业教育"舞龙头"的教学还有问题和"短板",应该改造教学方法和学习与研究制度。在剖析改造教学原因的基础上,厘清看待教学中存在问题的两种互相对立的态度,提出改造教学的革故鼎新路径,如强化"课堂教学为王"的意识,强化学习与专业研究,强化教学的职业素养,强化教师的课堂教学治理。     

被处罚的A级景区存在的问题及应对策略

旅游景区的管理与建设对旅游业的发展至关重要。然而,截至2019年7月底,全国有数百家A级景区由于管理与建设不善,受到摘牌、降级等处罚。对照《旅游景区质量等级的划分与评定》可以发现,被处罚的景区主要存在的问题:景区配套设施管理差、旅游交通不畅、游览设施与服务不健全、景区卫生差、景区市场吸引力小等。因此,政府必须与景区相配合,采取相应对策,强化景区建设与管理;提升景区资源、市场吸引力等,以扭转被动局面,推动旅游景区的健康发展。     

The role of involvement: Investigating the effect of brand's social media pages on consumer purchase intention

This study examined the influence of consumer's brand familiarity and the information quality of social media content on their involvement with a brand on the brand's social media pages. Also studied were the influence of involvement on consumer's attitude towards the brand's social media page and the effect of their attitude on future purchase intention from the brand. The results indicated that both brand familiarity and information quality had significant effects on a consumer's involvement with a brand on its social media page, yet the brand's social media content had a greater influence on a consumer's involvement with the social media page. Further, involvement with a brand's social media led to a positive attitude towards the brand's social media page, which in turn influences future purchase intention from the brand. However, the involvement did not directly influence future purchase intention from the brand. The results suggest the significant importance of quality of social media content.     

Feeling hungry? let's order through mobile! examining the fast food mobile commerce in China

This study proposes a unique framework that aids to enrich online shopping experience (psychological and monetary gains) and accelerates fast food mobile commerce (m-commerce). The extended technology acceptance model (TAM) is applied while the stimulus–organism–response (S–O–R) paradigm served as the predominant framework combined with the acquisition-transaction utility theory. This study investigates the mobile website quality, website brand equity (stimulus) influence on (PEOU) and (PU) (organism) to predict Chinese consumer intention to use fast food mobile commerce (response). A total of 936 respondents were participated while data were collected using a convenience sampling technique in China. Results reveal that all dimensions of mobile WQ (i.e., service quality, system quality, and information quality) and Website BE (i.e., brand image, perceived quality, brand association, and brand loyalty) (stimulus) significantly substantially influence PEOU and PU (organism) toward the acceptance of online fast food shopping (response). Digital Coupon Proneness (an accelerator) substantially moderates the relationship between PEOU, PU, and intention to use fast food m-commerce. Based on the assumptions of acquisition-transaction utility theory, category-specific (fast food) digital coupon proneness increase m-commerce for online fast food buying– a novel contribution of the study. Furthermore, research provides unique managerial insights for the industry to utilize the maximum potential of m-commerce in the fast-food industry.     

Investigating pharmaceutical logistics service quality with refined Kano's model

This study applies the refined Kano model and importance-satisfaction model to investigate medical institutions' satisfaction with and perceptions of importance of domestic pharmaceutical logistics services. Survey data involving 104 respondents from medical institutions are analyzed with importance-satisfaction and the refined Kano model. The results demonstrate that the refined Kano model will generate different classification of quality attributes for the pharmaceutical logistics industry, and medical institutions with different characteristics really have varying responses to quality attributes of pharmaceutical logistics services. The present research contributes to the literature by demonstrating that provision of high-value-added and crucial quality attributes by service providers can give them an edge in the market. In addition, when service providers understand their customers’ attitudes toward innovative service, it can enable them to strengthen their tactics in a competitive market.     

审计质量、产权性质对上市公司投资效率的影响研究

审计质量作为第三方会计师事务所为公司提供的服务,可以独立于公司之外对上市公司投资活动进行监督。根据产权理论,产权性质不同的经济组织从事的经济活动不同,审计质量对不同产权性质的上市公司投资效率的影响也不相同。本文以2014—2018年沪深两市上市公司作为样本,实证检验了审计质量、产权性质与公司投资效率间的关系。研究发现,审计质量与上市公司投资过度显著负相关,与投资不足负相关但作用并不明显;在国有上市公司中审计质量对投资过度行为的抑制作用更明显,在非国有上市公司中审计质量可以在一定程度上防止投资不足行为的发生但作用并不显著。研究结论有利于启示各不同产权性质公司的利益相关方,客观认识审计师的作用功能及其局限性,有针对性、有效率地利用好审计服务,改善公司投资效率。

On the Relationship between Audit Tenure and Fees Paid to the Audit Firm and Audit Quality

Abstract

We investigate the impact of audit firm tenure, partner tenure, audit fees, fees for non-audit services and total fees on audit quality, as measured by discretionary accruals. Our sample consists of Spanish non-financial public companies for the years between 2006 and 2013. Results indicate that audit quality increases with audit firm tenure but decreases with partner tenure. Moreover, the level of fees paid to the audit firm seems to have a negative impact on audit quality, which is mainly driven by fees for audit services. In this regard, we do not observe any significant relationship between fees for non-audit services and audit quality. Our results also show that the negative relationship between either long partner tenures or high fees and audit quality does not occur when the tenure with the audit firm is long. Therefore, long audit firm tenures do not only seem to involve higher audit quality ‘per se’, but also moderate the negative effects of partner tenure and audit fees on audit quality. The results of this study, which are robust to several sensitivity checks, may be relevant for the current debate on auditor rotation and the joint provision of audit and non-audit services.     

治理机制对顾客参与价值共创行为的影响——虚拟品牌社区的实证研究

虚拟品牌社区是企业与顾客进行价值共创的重要平台,顾客参与价值共创行为对企业长远发展具有十分重要的作用。现有研究多是基于不同的理论从顾客视角出发探索顾客参与价值共创行为受到的心理动机和个人特征等因素的影响,鲜有从企业视角出发,探索治理机制对虚拟品牌社区中顾客参与价值共创行为的影响。本文立足交易成本理论与社会交换理论,从企业视角切入,引入关系质量作为中介变量,构建虚拟品牌社区治理机制、关系质量与顾客参与价值共创行为的关系整合模型。采用问卷调查法对模型进行验证,研究结果显示:(1)契约治理机制只对知识贡献行为产生显著正向影响,对顾客公民行为的影响不显著,而关系治理机制对知识贡献行为与顾客公民行为均具有显著正向影响。(2)关系质量在契约治理机制与顾客公民行为的关系中起完全中介作用,在契约治理机制与知识贡献行为、关系治理机制与知识贡献行为以及关系治理机制与顾客公民行为的关系中起部分中介作用。由研究结论可知,虚拟品牌社区一方面应综合运用契约治理机制与关系治理机制来有效地促进顾客参与价值共创行为,以弥补单独运用某一种治理机制存在的不足;另一方面也应注重关系质量在虚拟品牌社区中促进顾客参与价值共创行为的重要作用。这些研究发现为促进虚拟品牌社区的可持续发展提供了有价值的启示。
