Procedures involving phlebotomy are critical for obtaining diagnostic blood specimens and represent a well known and recognized problem, probably among the most important issues in laboratory medicine. The aim of this report is to show spurious hyperkalemia and hypocalcemia due to inadequate phlebotomy procedure. The diagnostic blood specimens were collected from a male outpatient 45 years old, with no clinical complaints. The tubes drawing order were as follows: i) clot activator and gel separator (serum vacuum tube), ii) K₃EDTA, iii) a needleless blood gas dedicated-syringe with 80 I.U. lithium heparin, directly connected to the vacuum tube holder system. The laboratory testing results from serum vacuum tube and dedicated syringe were 4.8 and 8.5 mmol/L for potassium, 2.36 and 1.48 mmol/L for total calcium, respectively. Moreover 0.15 mmol/L of free calcium was observed in dedicated syringe. A new blood collection was performed without K₃EDTA tube. Different results were found for potassium (4.7 and 4.5 mmol/L) and total calcium (2.37 and 2.38 mmol/L) from serum vacuum tube and dedicated syringe, respectively. Also free calcium showed different concentration (1.21 mmol/L) in this new sample when compared with the first blood specimen. Based on this case we do not encourage the laboratory managers training the phlebotomists to insert the dedicated syringes in needle-holder system at the end of all vacuum tubes. To avoid double vein puncture the dedicated syringe for free calcium determination should be inserted immediately after serum tubes before EDTA vacuum tubes.  相似文献

Multifaceted Impact of Self-Efficacy Beliefs on Academic Functioning   总被引：13，自引：0，他引：13  

Albert Bandura  Claudio Barbaranelli  Gian Vittorio Caprara  Concetta Pastorelli 《Child development》1996,67(3):1206-1222

This research analyzed the network of psychosocial influences through which efficacy beliefs affect academic achievement. Parents' sense of academic efficacy and aspirations for their children were linked to their children's scholastic achievement through their perceived academic capabilities and aspirations. Children's beliefs in their efficacy to regulate their own learning and academic attainments, in turn, contributed to scholastic achievement both independently and by promoting high academic aspirations and prosocial behavior and reducing vulnerability to feelings of futility and depression. Children's perceived social efficacy and efficacy to manage peer pressure for detrimental conduct also contributed to academic attainments but through partially different paths of affective and self-regulatory influence. The impact of perceived social efficacy was mediated through academic aspirations and a low level of depression. Perceived self-regulatory efficacy was related to academic achievement both directly and through adherence to moral self-sanctions for detrimental conduct and problem behavior that can subvert academic pursuits. Familial socioeconomic status was linked to children's academic achievement only indirectly through its effects on parental aspirations and children's prosocialness. The full set of self-efficacy, aspirational, and psychosocial factors accounted for a sizable share of the variance in academic achievement.  相似文献

An interpretative model from the elasticity theory to explore knowledge integration in new product development     

Angelo?Corallo  Mariangela?Lazoi  Giustina?SecundoEmail author  Paolo?DePaolis 《知识管理研究与实践》2016,14(4):478-488

This paper presents a conceptual model to explore the knowledge integration (KI) practices of internal and external company actors involved in the New Product Development (NPD) process of the aerospace industry. The model is based on the linkage of elasticity principles, particularly Hooke’s Law, to Knowledge Management theory. KI practices are considered as a force pushing the NPD process and are metaphorically described as the spring addressed by Hooke’s law. The integration of the knowledge of internal and external company actors impacts NPD, reducing the dimensions of the whole process, in terms of phases, through the application of the concurrent engineering approach. The whole NPD process is improved in terms of the reduction of uncertainty and complexity, and with an ‘integrated energy’ that sustains the pressure of the fast-changing competitive environment. The model is explored to provide an interpretation of the conceptualisation phase of a new aerospace product development process. Qualitative data were collected and analysed. Insights regarding the applications of the model and the theoretical implications are also provided for applications in other industries.  相似文献   

Network time for the European Higher Education Area     

Rosaria Lumino  Paolo Landri 《Educational Philosophy and Theory》2020,52(6):653-663

Abstract

In this article, we discuss the process of standardization of Higher education (HE) initiated by the Bologna Process bringing to the forefront the temporal politics of the standardization of European Higher Education Arena (EHEA). Empirically, we perform a comparative review of the Scorecards indicators at the base of the Bologna Process monitoring project. We argue that the fabrication of EHEA could be seen as the installation of new time-space ‘time’ and ‘space’ appear inevitably intertwined. Instead of being a simple addition, the time space of EHEA interferes with the multiple time spaces of educational institutions and is characterized by being a network time, an unbroken and fragmented temporality sustained, enacted through, and controlled by the fluidity and the malleability of standards. They change recurrently over time, playing with different rhythms. What emerges is an overall arrhythmia that maintains the field permanently in tension. This reconfigures temporality as intrinsically manifold: as multiple and heterogeneous. Moreover, the temporal politics of standards reconfigures perception of past, present and especially future. The current state of implementation is constantly being (re)shaped in relation to the present and future performances, where’s one today level of EHEA targets achievement forms the basis for improvement tomorrow. In this scenario, assessing standards and headline targets become a policy instrument for synchronizing the countries performances, by locating them in a temporal framework that encodes future-oriented dispositions.  相似文献   

Stability and change of moral disengagement and its impact on aggression and violence in late adolescence     

Paciello M  Fida R  Tramontano C  Lupinetti C  Caprara GV 《Child development》2008,79(5):1288-1309

Stability and change of moral disengagement were examined in a sample of 366 adolescents from ages 14 to 20 years. Four developmental trajectories were identified: (a) nondisengaged group that started with initially low levels followed by an important decline, (b) normative group that started with initially moderate levels followed by a decline, (c) later desister group that started with initially high-medium levels followed by an increase from 14 to 16 years and an even steeper decline from 16 to 20 years, and (d) chronic group that started with and maintained medium-high levels. The results attest that adolescents who maintained higher levels of moral disengagement were more likely to show frequent aggressive and violent acts in late adolescence.  相似文献   

Academic stratification and functional theory     

David H. Kamens  Gian Sarup 《Research in higher education》1980,12(2):121-138

This paper examines empirically a set of propositions on organizational stratification drawn from functional theory. The data consist of 38 departments of a large university which are treated as contextual units, as well as the responses of individual faculty to a survey. The findings present an interesting theoretical paradox: (1) functional arguments do not appear adequate to account for differences in income stratification among departments, but (2) they do explain participants' beliefs and judgments about the legitimacy of organizational reward systems. The implications are discussed, and a line of inquiry is suggested that would focus on the problem of establishing legitimacy with the environment(s) as a major source of organizational structure. It is suggested that organizational features act as symbolic devices that inform others that a given organization is a competent member of its set. In short, it is conforming to agreed upon definitions of the appropriate—most rational—structure for thattype of organization.  相似文献   

Physiology in the Journal of Sports Sciences

Abstract

Doping in sports is commonplace. The prevention of harm to the athlete, the guarantee of fair play, and a level playing field for all competitors are the basis of the current anti-doping strategies. As healthcare systems are forced to allocate increasing resources to prevent and treat the prevailing pathologies worldwide, funding for anti-doping campaigns will necessarily be restricted. Ideally, additional resources should be devoted to increasing the number of athletes tested, the panels of tests used, and the frequency of out-of-competition controls. Since doping prevention cannot be considered a priority for most healthcare systems, such an approach is unaffordable and an alternative framework should be devised, focused primarily on harm reduction rather than fair play. The identification of abnormal deviations from reference values, regardless of pathological or artificial causes, would allow the athlete to be followed and tested using conventional laboratory tests, which are affordable to governments and healthcare systems and available to clinical laboratories. Although this strategy would not detect cheating, it would safeguard athletes' health.  相似文献   

Does Graduating from a Private University Make a Difference? Evidence from Italy     

Moris Triventi  Paolo Trivellato 《European Journal of Education》2012,47(2):260-276

The main aim of this article is to explore similarities and differences in the institutional features of private and state universities in the Italian higher education system and to assess whether graduating from a private university conveys advantages in the labour market. In the first part we use administrative data to describe the main institutional features of the two types of university, looking at organisational aspects, enrolments and graduates, financial resources, tuition fees, and teachers' characteristics. In the second part we develop a theoretical framework looking at sociological and economic theories of education and labour market, from which we derive some hypotheses on the expected results. In the last part, we apply a propensity score matching analysis on data from the Italian University Graduates Survey conducted in 2007 by the Italian National Institute of Statistics, which provides information on more than 40,000 graduates who obtained their degree in 2004. The main results indicate that graduates from private universities are younger, have a higher socio-economic background and a slightly better previous school career than those from state universities. Contrary to a widespread belief, once accounted for self-selection into the type of university using a wide range of variables, graduating from a private university has neither a significant nor a substantial effect on employment probability, hourly wage and occupational level three years after graduation.  相似文献
