果蔬胶带标签存隐忧

超市销售的蔬菜一般都被胶带捆扎成一把一把出售。虽然有些蔬菜是用保鲜膜包好然后再缠上胶带,但是多数超市中,娃娃菜、豆角、蒜苔等蔬菜都是直接被胶带捆扎着的。这些胶带有各种颜色,有些上面写着一些标签信息。除了蔬菜,水果表面也贴有标签,这些标签有些是塑料材质,有些是纸质的。胶带中黏合剂里面一般含有苯等对人体有害的物质,不能直接接触蔬菜和水果,从理论上讲,胶带中的化学物质会渗透到水果和蔬菜内部,虽然皮厚的水果可能避免受到污染,但是诸如苹果、梨等皮薄的水果则很难保证不被渗     

煤矿强力胶带输送机安装工艺

胶带输送机是煤矿生产应用最广泛的运输设备,具有距离长、运量大、输送连续等优点,同时也存在一些缺点和弊端,尤其以在运行中胶带跑偏最为突出。提高安装测量精度,保证安装的高质量是避免胶带跑偏的重要措施。文章结合嵩山煤矿东翼胶带输送机安装实例,探讨了大型胶带输送机的快速安装工艺。     

主井大倾角胶带输送机提速改造技术探讨

纵观我国现今所应用的主井大倾角胶带输送机,不仅胶带方面老化破损的程度相对较为严重,而且由此造成的机械事故也是频繁发生,主井大倾角胶带输送机在应用方面已经对人身、设备等多方面的安全造成了极大的威胁,同时也已经严重的制约了我国在矿井生产能力方面的进一步提高。因此,为了进一步的确保我国矿产在安全生产方面不受到相关的影响,我们必须在矿产生产方面进一步的提高改造现有的主井大倾角胶带输送机,最大化的利用我国现有设施,进而达到提高主井大倾角胶带输送机带速,增加主井大倾角胶带输送机运量以及满足我国矿井日常的运输任务的工作需要,提高主井大倾角胶带输送机等相关设备的安全系数,达到保障我国矿产安全生产的最终目的。     

胶带输送机跑偏原因分析及处理

胶带输送机具有输送距离长、运量大、连续输送等优点,而且运行可靠,易于实现自动化和集中化控制。在氧化铝生产系统中,胶带输送机也得到了广泛的应用,成为保证生产连续运行的关键设备。但是皮带跑偏作为胶带输送机最为常见的设备故障,很大程度影响着设备的正常运行,进而影响生产稳定运行。所以文章针对氧化铝焙烧车间胶带输送机系统易出现跑偏导致胶带输送机被磨损的现象进行分析,在找出问题根源之后,根据现场的实际情况结合可参照的资源,制定能够解决胶带输送机跑偏的措施,以保证设备的生产效率。

粘箱机在生产中的优势及其未来发展趋势探讨

随着科技的不断发展和进步,绿色环保概念的不断深化,市场对瓦楞纸板这类绿色环保包装产品的需求量不断增加,对瓦楞纸箱的成品质量及回收利用等要求也不断提高。相对于传统的钉箱、胶带工艺,粘箱机在瓦楞板箱生产中的优势明显,更利于环保,其未来发展空间相当可观。     

商情与预测

高质量粘合纸箱前景亮丽目前,我国出口食品所用的纸箱,大多用金属钉装订。用PYC胶带封箱,有的纸箱还用蜡纸或油质隔层;少数粘合纸箱因粘合剂不过关,质量不高,难以进入国际市场。这已成为影响我国食品出口的一大难题。根据有利于环境保护的原则和外商的要求,我国出口食品包装所用的高质量纸箱只能粘合,不能使用任何金属或塑料装钉,封箱也不用PYC或其他塑料胶带,而代之以粘合剂;外纸箱不能有腊纸或油质隔层等等。只有这样才能方便回收,减少对环境的污染,     

超市缠菜胶带多为工业胶带

正在超市,蔬菜用胶带捆绑是司空见惯的事儿。但近日,网上热传:"这些胶带多为‘工业级’非食品包装材料,不利于人体健康。"更有网帖称:"目前内地并无食品级胶带,这些‘工业级胶带’中含有苯类、甲醛、重金属等有害物质。"有网友对此表示担忧,认为:"用这些胶带捆绑食物,虽然对人体构不成直接、急性的危害,但如果长期摄入,会对人体造成潜在的伤害,塑料中所含的塑化剂,会向蔬菜内部迁移。"

Objective Formalization,Perceived Formalization and Perceived Red Tape

Abstract

This research uses survey data and count data of formal rules in a Dutch organization to investigate the relationships between an objective measure of formalization and subjective measures of formalization and red tape. We find that red tape perceptions are related to perceptions of formalization. Second, we find that perceived formalization is weakly, significantly related to objective measures of formalization but that objective formalization measures do not correspond to higher levels of red tape perceptions. We conclude that red tape and formalization are distinct concepts, but question the claim that formalization is a necessary condition for red tape.

Structure and Perceived Performance in Public Organizations

Abstract

The purpose of this study is to examine relationships and better-fits between organizational structure and performance in public organizations. This study takes into account multiple dimensions of organizational structure: span of control, organizational personnel size, global organizational red tape and personnel red tape. The relationships between the first two physical dimensions and perceived organizational performance are examined by taking different combinations of measures, such as raw measures, log-transformation measures and squared measures. The results of ordinal logistic regression models find that, except for span of control, the other structural dimensions have a negative influence on perceived organizational performance. While span of control shows a better-fit with perceived performance in a linear and positive direction, personnel size fits better in a log-linear relationship. Theoretical and practical implications are discussed in the conclusion.     

Personnel Formalization and the Enhancement Of Teamwork: A public–private comparison

Formalization has long been regarded as one of the most distinctive features of the public sector. Personnel systems in the public sector are particularly formalized due to merit system protections and strong due process requirements. In much of the contemporary public management literature, personnel formalization implies red tape, referring to excessive rules that bring negative outcomes such as employee frustration. The present study offers an alternative view, suggesting that personnel formalization results in high-performance work practices, particularly teamwork, by ensuring that organizations attract the right employees and provide employees with various protections such as worker safety, procedural justice and conflict resolution. Given that public organizations are structured more formally, public sector employees are more likely to work in teams than their peers in the private sector. The authors test this view by using variables from the National Organization Survey (NOS) data set and find strong statistical support. Therefore, personnel formalization is not necessarily equivalent to red tape and not always detrimental to the public sector. It enhances teamwork, a central element of high-performance work practices.     

Work motivation and social communication among public managers

This article tests hypotheses about the effects of two types of work motivation (i.e. intrinsic motivation and extrinsic motivation) and four types of social communication on three important work dispositions (i.e. job involvement, red tape, and perceived organizational effectiveness) among 790 managers employed in public agencies in the states of Illinois and Georgia. The results show that intrinsic motivation is significantly associated with public managers' job involvement, perceptions of red tape, and organizational effectiveness. Also, certain types of organizational communication and mentoring socialization are closely related to the outcomes. The results of cross-interaction effects between motivation and communications on outcome variables support the SDT prediction that when public managers are more involved with different types of social communication behaviors, the relationship between extrinsic motivation and three outcome variables becomes more pronounced. That is, communication in public agencies provides more autonomy and discretion for extrinsically motivated public managers, thus leading to more positive organizational dispositions.
