Microbiological and Modeling Approach to Derive Performance Objectives for Bacillus cereus Group in Ready‐to‐Eat Salads

In this article, the performance objectives (POs) for Bacillus cereus group (BC) in celery, cheese, and spelt added as ingredients in a ready‐to‐eat mixed spelt salad, packaged under modified atmosphere, were calculated using a Bayesian approach. In order to derive the POs, BC detection and enumeration were performed in nine lots of naturally contaminated ingredients and final product. Moreover, the impact of specific production steps on the BC contamination was quantified. Finally, a sampling plan to verify the ingredient lots' compliance with each PO value at a 95% confidence level (CL) was defined. To calculate the POs, detection results as well as results above the limit of detection but below the limit of quantification (i.e., censored data) were analyzed. The most probable distribution of the censored data was determined and two‐dimensional (2D) Monte Carlo simulations were performed. The PO values were calculated to meet a food safety objective of 4 log₁₀ cfu of BC for g of spelt salad at the time of consumption. When BC grows during storage between 0.90 and 1.90 log₁₀ cfu/g, the POs for BC in celery, cheese, and spelt ranged between 1.21 log₁₀ cfu/g for celery and 2.45 log₁₀ cfu/g for spelt. This article represents the first attempt to manage the concept of PO and 2D Monte Carlo simulation in the flow chart of a complex food matrix, including raw and cooked ingredients.     

Linking government social media usage to public perceptions of government performance: an empirical study from China

Based on an online survey of 1042 Beijing residents, this study links the usage of government social media tools, including WeChat, microblogs, and apps, to public perceptions of the government’s performance. The results indicated that young people are more likely to use government microblogs. In contrast, an inverted U-shaped relationship was found between age and the utilization of government WeChat and apps. The findings also showed that people with high education, high economic status, and a local hukou were more likely to use all three government social media tools. In controlling for the demographic variables, the results showed that the most important predictor of the use of a government social media tool was the use of any other government social media tool. The general use of social media significantly influenced the use of government social media tools, whereas the direction of this influence depended on the homogeneity or heterogeneity of these behaviors. Moreover, the results revealed a linkage between government social media use and public perceptions of government performance. Functional use, especially information acquisition and participation, was a significant predictor of perceived government transparency, responsiveness, and citizen satisfaction, while the public service function significantly increased perceived government responsiveness.     

晋升激励、地域偏爱与企业环境表现:来自A股上市公司的经验证据

晋升激励和地域偏爱是影响地方政府官员决策行为的关键因素。本文以2009-2015年沪深A股上市企业为样本，探讨官员更替对企业环境表现的影响，并分别从晋升激励和地域偏爱两个角度切入分析这种影响背后的机制。研究发现，地方政府换届后，若继任官员来自本地调任，则当地企业的环境表现将得到改善；而若继任官员来自异地调任，则当地企业的环境表现将发生恶化。这一研究结论在解决可能的内生性问题、改变度量指标、考虑滞后反应、进行安慰剂测试、调整样本及控制其他可能的遗漏变量等一系列稳健性测试后仍然成立。进一步研究发现，异地调任的继任官员出于晋升激励的动机而倾向于降低地方环境治理水平；而本地调任官员出于对曾经任职地区的地域偏爱而更重视当地环境治理。本文创新性地从地方官员的晋升激励和地域偏爱视角探讨企业的环境社会责任，为理解地方官员的决策模式和企业环境责任行为提供了新思路。

The effect of charitable giving by celebrities on the personal public relations

This study examined how charitable giving by entertainment celebrities influences celebrity personal public relations. Survey participants showed positive attitudes toward charitable giving. Attitudes toward charitable giving positively influenced celebrity credibility perception. Credibility also influenced attitudes toward the celebrities, which in turn positively influenced the purchase intention of their performance. Also, attitudes toward charitable donations were positively associated with attitudes toward the celebrities. Scholars and practitioners need to note charitable giving as an efficient and strategic personal public relations factor and method.     

The impact of lean practices on operational performance – an empirical investigation of Indian process industries

In deciding to adopt lean manufacturing, it is imperative to investigate where and how lean practices are most needed to influence manufacturing and business performance. Such an investigation becomes indispensable when lean thinking is to be considered in a production arrangement different to the conventional, repetitive, high-volume, stable-demand and discrete-manufacturing environment. This study provides explanations of how performance is improved through the adoption of lean practices in process industries. This is a relatively under-researched area compared to the performance effects associated with the introduction and implementation of lean principles in traditional, discrete manufacturing. Based on a survey of Indian process industries, this study attempts to develop an empirical relationship between lean practices and performance improvement through the use of multivariate statistical analysis. The findings have led to the conclusion that lean practices are positively associated with timely deliveries, productivity, first-pass yield, elimination of waste, reduction in inventory, reduction in costs, reduction in defects and improved demand management. However, within a process-industry context, lean practices related to pull production were found to have a marginal impact on performance improvement. A detailed discussion of the findings along with their theoretical and managerial implications is provided in the paper.     

Human resource management,employee engagement,and nonprofit hospital performance

Human resource management (HRM) has been shown to impact organizational performance, but more research is needed on particular human resource (HR) practices in nonprofits and their effect on performance. In this article, we explore one HRM practice argued to influence performance, employee engagement in decision‐making, examining whether involving staff at different levels of a nonprofit affects nonprofit organizational performance. Drawing on data from a 2011 study of nonprofit hospitals, we find employee engagement has a positive influence on managerial and stakeholder perceptions of organizational performance. Employee engagement in decision‐making is also related to objective nonprofit performance measures, although the effects are less consistent. We conclude by discussing the implications of these findings for nonprofit research and practice.     

Collective voice mechanisms,HRM practices and organizational performance in Italian manufacturing firms

The literature on employee voice has grown enormously over the past decades. However, the relationships between different employee voice mechanisms and organizational performance are far from being fully understood, and the existing research shows mixed evidence. Moreover, the HRM literature tends to concentrate on individual voice mechanisms (e.g. employee involvement) and to underestimate the role that collective voice may have in the HRM performance relationship. This paper aims to analyze how collective employee voice mechanisms (i.e. union voice and team voice) affect organizational productivity and how these relationships vary when voice mechanisms are adopted in combination with other HRM practices (i.e. variable pay, training, performance appraisals and multitasking). The analysis of a sample of 223 Italian manufacturing firms matched with an external database (AIDA) containing balance sheet information found that union voice is positively related to labor productivity, while team voice does not show any significant relationship with labor productivity. Moreover, both union and team voice have important moderation effects in the HRM-performance relationship. Union voice moderates positively the relationship between variable pay and performance and negatively the relationship between training and performance. Team voice positively moderates the relationship between training and performance. The implications of these findings are discussed.     

Managing stakeholder pressures: Toward a typology of corporate social performance profiles

Why do some firms ignore some stakeholders while courting others? We propose two key drivers of firms' social postures and derive from this analysis a novel typology of corporate social performance (CSP) profiles. Although we expect that other drivers exist, we argue that a useful starting point for understanding any given CSP profile is to consider the pressure exerted on an organization by its stakeholders in conjunction with its level of resource endowment. Our preliminary typology identifies six distinct CSP profiles that reflect different opportunities and risks for stakeholder management: the CSP Vanguard, Opportunist, Generalist, Minimalist, Specialist, and Laggard. All else equal, the first two CSP profiles imply more nonmarket opportunities than risk, whereas we expect Laggards and Specialists to face greater risk in their responses to social and environmental issues. According to our framework, Generalists and Minimalists probably operate between these two extremes of business risk. Our conceptual analysis seeks to advance research and practice for more strategic stakeholder management.     

Balancing employees’ extrinsic requirements and intrinsic motivation: A paradoxical leader behaviour perspective

In this paper, we use self-determination theory to examine the benefits of the use of paradoxical leader behaviour (PLB) by supervisors. We posit that PLB can initiate two complementary mechanisms: a top-down mechanism (perception of leaders' legitimate power) that may encourage employees to satisfy and exceed standard performance criteria, and a bottom-up mechanism (employee intrinsic motivation) that stimulates employees to be proactive. We argue that implementing these mechanisms simultaneously may interactively enhance employee creativity. Our study is based on field data collected from a sample of 392 employees and their supervisors. We find that PLB is positively related to employees’ perception of legitimate power and intrinsic motivation. Furthermore, power perception and intrinsic motivation are associated with standard performance and proactive behaviour, respectively, and these mechanisms jointly influence employee creativity. In demonstrating the efficacy of balancing extrinsic requirements and intrinsic motivation, our findings have significant theoretical and empirical implications for employee motivation.
