Ear surgery in many ways lagged behind other surgical fields because of the delicate anatomical structures within the ear which leave surgeons with little room for error. Thus, while surgical instruments have long been available, their use in the ear would most often do more damage than good. This state of affairs remained the status quo well into the first half of the 20th century. However, the introduction of powered surgical instruments, specifically the electric drill used in conventional microscopic ear surgery (MES) and the ultrasonic aspirator, the Sonopet® Omni, in transcanal endoscopic ear surgery (TEES) marked major turning points. Yet, these breakthroughs have also raised concerns about whether the use of these powered surgical instruments within the confines of the ear generated so much noise and vibrations that patients could suffer sensorineural hearing loss as a result of the surgery itself. This paper reviews the intersection between the noise and vibrations generated during surgery; the history of surgical instruments, particularly powered surgical instruments, used in ear surgeries and the two main types of surgical procedures to determine whether these powered surgical instruments may pose a threat to postoperative hearing.

1848 has gone down in history – or rather in history books – as the year when England was different. In that year a wave of revolution on the Continent overthrew constitutions, premiers and even a dynasty but in England, by contrast, the middle classes rallied round the government and helped it preserve the status quo. This interpretation of 1848 has long been the established orthodoxy amongst historians. Asa Briggs took this view thirty years ago and it has lately been endorsed by F. B. Smith and Henry Weisser. Most recently, John Saville, in his book on 1848, has concluded that events in England ‘demonstrated beyond question and doubt, the complete and solid support of the middling strata to the defence of existing institutions’. He claims that ‘the outstanding feature of 1848 was the mass response to the call for special constables to assist the professional forces of state security’ which reflected a closing of ranks among all property owners. Although some historians, notably David Goodway, have recently stressed the vitality of Chartism in 1848 they have not challenged the traditional view that the movement failed to win concessions from the establishment and soon declined. Thus 1848 in England is generally regarded as a terminal date: the last chapter in the history of Chartism as a major movement. Thereafter Britain experienced a period of conservatism – described by one historian as ‘the mid-Victorian calm’–which lasted until the death of Palmerston in 1865.

Belarusian citizens elected their first president in 1994. More than 20 years later, in October 2015, the same person triumphantly won the fifth consecutive presidential election. In August 2020, President Lukashenko’s attempt to get re-elected for the sixth time ended in months’ long mass protests against the electoral fraud, unspeakable violence used by the riot police against peaceful protesters and the deepest political crisis in the modern history of Belarus. This article analyzes how and why the first democratically elected Belarusian president attained this long-serving status. It suggests that his political longevity was conditioned by a specific social contract with the society that was sustained for many years. In light of the recent events, it is obvious that the contract is breached with the regime no longer living up to the bargain with the Belarusian people. As a result, the citizens seem unwilling to maintain their obligation for loyalty. We analyze the escalating daily price for maintaining the status quo and conclude considering the possible implications of this broken pact for the future of Belarus.

Abstract The essence of education is to prepare an individual for lifelong experiences after schooling. Education as offered in schools today is expected to give the teacher a chance to impart knowledge and skills in the learner, and for the learner to be informed and be able to put into practice what has been gained in the course of time. The Kenyan curriculum and goals of education are clearly stipulated if followed to the latter. Basically, the classroom practice by both the teachers and the learners exhibit an academic rather than a dual system that is expected to meet the needs of both the individual and those of the communities which form subsets of the society at large. It is upon this premise that education of a given country must prepare its individuals in schools so as to meet the goals of education at any one given time of a country’s history. This paper looks at the perspective of vocationalization of education in Kenyan at this century. The history of education ever since independence in 1963 by focusing on the Ominde commission through the Koech report of 1999 have been emphatic that education must meet the national goals of education as stipulated in the curriculum. But what is edging the practice that has not revolutionalized the socio-economic, cultural and political development of Kenya? Differentiated Instruction is a teaching theory based on the premise that instructional approaches should vary and be adapted in relation to individual and diverse students in classroom aimed at achieving diversified learning and common practices in the career. The challenges herein are: where have we gone wrong as a nation, what is the practice in the classroom, when can the nation be out of this dilemma, who is to blame for the status quo and finally what is the way forward? By addressing these questions, the education system will be responsive to the changes in time and Kenya will be on the path to successful recovery.

Abstract Whenever one reads internal histories of psychology what is covered is the establishment of a lab by Wundt in 1879 as the initiating act and then the breakaway movements of the 20th Century are discussed: Behaviorism, Gestalt Theory, Psychoanalysis, and most recently the Cognitive revival. However, Aron Gurwitsch described a perspective noted by Cassirer and first developed by Malebranche, which dates the founding of psychology at the same time as that of physics in the 17th Century. This external perspective shows the dependency of psychology upon the concepts, methods and procedures of physics and the natural sciences in general up until the present time. Gurwitsch argues that this approach has blocked the growth of psychology and has assured its status as a minor science. He argued that the everyday Lifeworld achievements of subjectivity are the true subject matter of psychology and that a phenomenological approach to subjectivity could give psychology the authenticity it has been forever seeking but never finding as a naturalistic science. Some clarifying thoughts concerning this phenomenologically grounded psychology are offered, especially the role of desire. The assumption of an external perspective toward the history of psychology fostered the insights about psychology’s scientific role.

The benefits of full ectogenesis, that is, the gestation of human fetuses outside the maternal womb, for women ground many contemporary authors’ arguments on the ethical desirability of this practice. In this paper, I present and assess two sets of arguments advanced in favour of ectogenesis: arguments stressing ectogenesis’ equality-promoting potential and arguments stressing its freedom-promoting potential. I argue that although successfully grounding a positive case for ectogenesis, these arguments have limitations in terms of their reach and scope. Concerning their limited reach, I contend that ectogenesis will likely benefit a small subset of women and, arguably, not the group who most need to achieve equality and freedom. Concerning their limited scope, I contend that these defences do not pay sufficient attention to the context in which ectogenesis would be developed and that, as a result, they risk leaving the status quo unchanged. After providing examples of these limitations, I move to my proposal concerning the role of ectogenesis in promoting women’s equality and freedom. This proposal builds on Silvia Federici’s, Mariarosa Dalla Costa’s and Selma James’ readings of the international feminist campaign ‘Wages for Housework’. It maintains that the political perspective and provocation that ectogenesis can advance should be considered and defended.

This article presents an account of an interview with Zdzisław Fedak, PhD, who participated in the work on the systemic solutions in accounting in the People’s Republic of Poland (PRL), and currently is an animator of improvements in Polish accounting practice in the conditions of market economy. The basic reason for this publication is the need to fill the gap in the picture of the determinants and characteristics of accountancy in Poland in the period of non-market economy, taking advantage of the expertise and experience of people knowing the status quo in this area. This text is part of the trend to document the history of accountancy by means of a research method known as oral history.

The Right of Minors to Freedom from Gambling and Internet andGaming Addition The aim of the article is to highlight the dangers of gambling and Internet and gaming addiction of minors and young persons. The author is convinced that in the absence of positive legislative changes and if creators of games engaging young persons in gaming are not punished, children will not be safe in the online environment. There will not have any other lives than those in the games they play. Additionally, the most important thing is the role of the parents, guardians and teachers. They should talk to children about the problem, show them the dangers and organise better their free time – in an educational and carefree way. In accordance with the obligatory rules of custody, they should ensure them suitable development, safety and a sense of belonging. The teachers ought to support these activities. Summarising, if the status quo continues to be tolerated, minors and young person’s will be deprived of carefree life and suffer from harm and even sudden deaths. The author is sure that parents and children do not give enough attention to that and we should not take away from young person’s the joy of simple things letting them play in the Internet instead.

The history of asepsis and antisepsis has been presented along with the doctors and scientists acclaimed in the field. Ignacy Semmelweis (1818 – 1865), an obstetrician from Vienna, noticed that the puerperal fever arises from the fact that doctors and students after their classes in dissecting room come to the rooms for the ill in hospitals without washing their hands. But, his recommendations to wash hands in chlorine water were criticized and rejected. Józef Lister (1827 – 1912), an English surgeon, after the discovery of pyogenic bacteria such as staphylococcus and streptococcus by Ludwik Pasteur (1822 – 1912), suggested washing hands and sterilization of the surgical instruments and dressings as well as spraying the operating rooms with the use of carbolic acid. He is considered to be the father of antisepsis. The paper also underlines the role of Kurt Schimmelbusch (1870 –1895) in fighting with the perioperative infections. He was the creator of an autoclave used for sterilization of surgical materials and instruments. Jan Mikulicz Radecki (1850 – 1905), from Wrocław, was the first to use a sterile uniform with a face mask and cotton gloves for surgical treatments.
