职业延迟满足对员工过劳的影响研究——职业成长机会的调节作用

目前，员工过劳问题在我国企业发展中日益凸显，需要予以重视和解决。基于个体与组织互动角度，通过对338名企业员工的问卷调查分析职业延迟满足和职业成长机会对员工过劳的影响，并检验职业成长机会对职业延迟满足影响员工过劳的调节作用，结果表明：职业延迟满足的两个维度（工作延迟满足和职业生涯延迟满足）均对员工过劳有显著正向影响，而职业成长机会对员工过劳有显著负向影响；职业成长机会对职业延迟满足影响员工过劳具有负向调节作用，即职业成长机会越大，职业延迟满足与员工过劳的正向关系越弱。因此，企业管理者应合理引导和帮助员工做好职业生涯规划，为员工提供合适的多元化发展通道，以有效预防和缓解员工过劳。     

一种动态加权的LDPC译码方法

为了加快低密度奇偶校验（LDPC）码的译码速度，有效改善LDPC码的译码性能，针对校验节点更新过程中的对数似然比（LLR）值的大小，设计了一种LDPC码的动态加权译码方法。以IEEE 802.16e标准的奇偶校验矩阵为例，根据LLR值的变化规律，利用增长因子和抑制因子对和积译码算法和最小和译码算法进行动态加权。仿真结果显示，基于动态加权的译码方法相对于传统译码方法误码率都有明显改进，译码复杂度也有所降低。     

Tourists’ hotel event experience and satisfaction: an integrative approach

ABSTRACT

Tourists’ hotel event experiences have received little attention in tourism research. By proposing an integrated model of expectation–confirmation theory (ECT) and the experience economy concept, this research explores the relationship between tourists’ event experience and their satisfaction regarding the hotel event setting. The hypothesized model was empirically validated using a sample of 663 tourists who experienced a holiday event at a resort hotel. Results confirmed that the integration of the experience economy and ECT provided a better understanding of tourists’ post-satisfaction in a pleasure-driven setting. This affective–cognitive approach advances the knowledge of tourists’ experiences and satisfaction at hotel events.     

Managerial optimism: New observations on the unifying theory

Managerial optimism theory is behavioral finance's greatest achievement. It explains two prominent features of corporate financial behavior – over‐investment and pecking‐order capital structure preferences – that otherwise require two different theories with mutually incompatible assumptions about managerial loyalties to shareholder‐value maximization. After reviewing the development of managerial optimism as a unifying theory, I use a simple change of measure to transform risk‐averse optimism to risk‐neutral probabilities that can be pessimistic or optimistic depending on wealth changes. This unexplored feature has implications for, among other things, pay for performance when managers are excessively optimistic.     

国内外社会资本与旅游研究文献综述

社会资本包含集体社会资本和个体社会资本。通过对Elsevier，Springer link和CNKI等平台上的文献进行梳理发现：在旅游领域，社会资本理论研究主要集中于集体和个体社会资本对旅游发展影响以及旅游对目的地社会资本影响等方面，研究呈现出内容上集中于社会资本对旅游的影响，方法上以案例分析为主的特点，当前仍存在不足，并提出今后研究的趋势，为以旅游创新助力乡村振兴，关注特色小镇发展模式，促进文化旅游可持续等，更好地运用社会资本理论来解释和解决旅游活动中的现象和问题，促进旅游业可持续发展。     

Feeding management of dairy cattle affect grassland dynamics in an alpine pasture

The effect of different supplementary feeding rates for grazing cattle on high-altitude pastures dynamics was evaluated. A field experiment was carried out during three years in a subalpine pasture area of the Eastern Alps. The investigated pasture area was 40?ha, located between 1820 and 2230?m?a.s.l. Two paddocks were chosen in the experiment and two herds of 12 cattle each were kept in the two enclosures for 5 weeks. For the first herd (HS), the supplementary feeding rate was 4.8?kg?OM?head^?1 per day, while for the second herd (LS), the rate was 1.6?kg?OM?head^?1 per day. The amount of herbage consumed by each cattle was determined using the n-alkane technique. To monitor the pasture vegetation dynamics, eight metal exclusion cages were placed in each paddock to determine herbage growth, utilization rates, vegetation composition and animal grazing selectivity. Grazing behaviour of dairy cattle, in terms of herbage intake and species selection was affected by the different feeding rates. Cattle grazing Paddock HS consumed 1.9?kg?OM?day^?1 of herbage less than Paddock LS. In the LS paddock, cattle grazed higher phytomass rates. When the animals were fed by higher concentrate rates, a more selective grazing seemed to significantly increase the pasture necromass component. The lower grazing selectivity favoured the development of species as Nardus stricta and Deschampsia caespitosa, which are well known for their low palatability. Distinct vegetation dynamic patterns were observed, with a reduction of hair grass and an increase of legumes in the Paddock LS.     

Reinterpreting the theory of planned behavior and its application to green hotel consumption intention

The main aim of this paper was to understand a guest’s decision to stay at a green hotel by using the theory of planned behavior (TPB) developed by Ajzen (1991). The population for this study was green hotel customers in Taiwan. A total of 425 usable responses were received from the willing participants around the parking area of green hotels. This study performed a PLS-SEM to examine the proposed model. The results of this study showed that social pressure has very little direct impact on behavioral intention to stay at a green hotel. The results of the estimated standardized regression coefficients and t-values indicated that perceived behavioral control has a slightly higher impact on behavioral intention than attitude. This study also verified the proposed mediating relationships between the first-order and second-order antecedents. This study provided theoretical and managerial implications for understanding respondents’ decision to stay at a green hotel.     

Examining the extent of and determinants for sustainability assurance quality: The role of audit committees

This study examines the extent of and determinants for sustainability assurance quality. Data comprise sustainability assurance statements published by the top 100 listed companies in Australia and New Zealand from 2017 to 2019. The findings indicate that Australian companies lead their New Zealand counterparts in sustainability assurance. Although sustainability reporting has risen, assurance rates remain significantly low. Accountants dominate the market, and companies prefer to use their own auditors for sustainability assurance work. Sustainability assurance quality is poor and does not vary significantly among Australian and New Zealand companies. Low-quality sustainability assurance plays a limited role in mitigating potential stakeholder–agency conflicts. The regression analysis indicates that audit committee characteristics such as members' independence, industry/market expertise, and attending meetings enhance sustainability assurance quality, whereas audit committee size has no affect. These findings suggest that audit committee characteristics such as independence, industry expertise, and regular meeting attendance have the potential to reduce stakeholder–agency conflicts by improving the quality of sustainability statement assurance. Our findings build on the sustainability assurance literature by exploring current trends in sustainability assurance practices in Australia and New Zealand where corporate governance codes have been recently revised. Further, these findings are timely given recent changes in standards (International Standard on Assurance Engagements [ISAE] 3000 and Global Reporting Initiative [GRI]). Our study contributes to the audit committee literature and sheds light on the role played by audit committee characteristics on sustainability assurance statement quality. The study findings potentially offer useful insights for practitioners, standard setters, and regulators.     

Investigating menu kilojoule labelling policy adoption from a political science perspective

Implementation of internationally recommended policy options for obesity prevention has generally been slow and inadequate globally, and, as such, it is important to understand barriers and enablers to policy action in the area. This study aimed to apply political science theories to understand influences on the adoption of Menu Kilojoule Labelling Legislation in Victoria, Australia over the period 2009–2017. Data collection included 13 in-depth semi-structured interviews with participants of the policy development and decision-making processes, analysis of 68 policy documents, and field note observations. Data were analysed using established political science theories: the Advocacy Coalition Framework (ACF) and the Multiple Streams Theory (MST). There were numerous and interrelating factors that influenced the Menu Kilojoule Labelling Legislative policy processes. Barriers to policy reform included electoral turnover, a dominance of neoliberal ideology, and policy maker concerns regarding potential food industry backlash. Key enablers to eventual policy change included the accumulation of evidence on policy effectiveness and feasibility of implementation, increased recognition of the importance of tackling the issue, as well as reductions in political risks achieved, in part, through relatively long consultation and negotiation processes. Findings highlight several tactics that can be used to secure similar policy change in future, including generation, dissemination and translation of implementation evidence, effective mobilisation of supporters, and negotiation and consultation processes that can reduce the degree of opposition to proposed policies.     

LEADERSHIP IN CLIMATE CHANGE MITIGATION: CONSEQUENCES AND INCENTIVES

Initiatives in favor of unilateral action on climate change are frequently challenged by concerns over free riding. Nevertheless, we observe an increasing number of unilateral efforts at different administrative levels and in different parts of the world. Previous academic literature described various individual mechanisms where emissions abroad may increase or decrease as a reaction to unilateral emission reductions. In this paper, we collect a comprehensive set of both positive and negative reactions and analyze them in stylized models. This allows us to identify the most important characteristics that determine the potential of a leader to boost mitigation efforts abroad. We find that this potential depends on (i) a strong ability to generate knowledge through leadership, (ii) a high degree of credibility in the international community, and (iii) a similar economic structure to the most important emitters. While most effects are difficult to quantify, this comprehensive assessment suggests that leakage effects resulting from unilateral mitigation may well be outweighed by positive reactions.
