Critique of Sharif’s and Pitt’s Models of Technology

abstract

In this article Pitt’s and Sharif’s models of technology are discussed. These models are based on two different conceptions of technology, which are technology as “instrument” and as “making use of instrument.” Sharif considers technology as a collection of empowering tools, including technoware, humanware, infoware and orgaware. On the other hand, Pitt sees technology as “humanity at work.” Based on his definition, Pitt proposes a model of technology with three components; first-order transformation, second-order transformation, and the assessment of feedback mechanism. In this article this model will be explained and criticized. After that, Sharif’s model is criticized in the light of Pitt’s theory and it will be shown that Pitt’s model provides a better understanding of different aspects of technology. For example, it will be argued how Pitt’s model is efficient in explaining dynamicity, transfer and control of technology along with its soft dimensions, while Sharif’s model is incapable of doing so. In the next part, Pitt’s model is criticized and it is shown that the mechanism of knowledge progress suggested by this model is controversial and Pitt’s framework cannot support the idea of indigenous technology. Furthermore, the ability of Pitt’s model in describing different technological phenomena is called into question, since this model provides a superficial view of the complexity of an assessment of technology’s consequences. Finally, a list is proposed that contains minimal requirements that every model of technology is expected to explain. It is incumbent on technology theoreticians to consider this list.     

Communication,reflexivity and harm principle: what might an ideal speech situation look like in responsibility to protect?

ABSTRACT

Previous accounts of International Relations research have extensively focused on deontological ethics in analysing Responsibility to Protect (R2P). At the same time, discourse ethics – along with Jürgen Habermas’ theory of ideal speech situation – has been overlooked. This article argues that the R2P process has gradually moved toward the Habermasian ideal speech situation. The Habermasian approach also provides a useful theoretical framework to understand the new, more inclusive and critical, forums of communication and initiatives set in motion by emerging non-Western norm-entrepreneurs in the R2P process, notably the Responsibility while Protecting (RwP) initiated by Brazil in 2011. From the perspective of discourse ethics, RwP could be understood as a cosmopolitan harm principle designed to manage the potentially harmful side-effects of the application of R2P. The article further argues that, despite the current paradigm shift of norm-entrepreneurship on R2P from deontological ethics to discourse ethics, it has thus far only partially fulfilled the criteria of an ideal speech situation.     

Prediction of weightlifter’s motor behavior to evaluate snatch weightlifting techniques based on a new method of investigation of consumed energy

Using proper technique in different sports is an inevitable factor. In this study, available techniques for snatch weightlifting are mathematically evaluated. The optimal motion trajectory is a technique used by weightlifters, which could be determined based on minimizing specific object functions. Object functions based on total kinetic energy, total torque and total power and some new multiobjective functions are minimized using genetic algorithm and the minimax principle. Some important motion characteristics of 13 professional weightlifters were extracted and used to validate the mathematical results. The double knee bending (DKB) technique was studied as a benchmark test. Some important movement features of the technique were shown by the mathematical analysis when applying an object function, that minimized joint torques and powers of different muscles independently. An object function based on joint forces did not show these features.     

重症胰腺炎外科治疗观之辩

分析了当前外科治疗重症胰腺炎（ＳＡＰ）原则仍然不能提高手术后生存率的原因，用辩证法的观点，剖析当代手术治疗ＳＡＰ的误区，提出判断ＳＡＰ手术时机的简易方法和ＳＡＰ开腹手术的基本原则，应该按照辩证法的观点来正确看待ＳＡＰ的手术时机，应该用发展的眼光来分析传统治疗ＳＡＰ的手术方法，不能用一成不变的观点对待传统的手术方式，不能照搬书本教条，不能违背外科手术的基本原则。只有这样才有助于提高外科治疗ＳＡＰ的成功率。
