Abstract

Purpose

This study aims to explore Asian American students’ identities and their perceptions about who they are within the Midwestern American high school setting.

Design/methodology/approach

A naturalistic inquiry (Lincoln and Guba, 1985) is employed in this qualitative study. Naturalistic inquiry assumes that reality is constructed by individuals, and there exist multiple realities as diverse people experience teaching and learning (Glesne, 1999). It is characterized by natural settings (the schools), natural language (language actually used by students and teachers), responsiveness to concerns and issues of stakeholders (what is important to students and teachers) and collaborative checks on trustworthiness.

Findings

The study finds that the participants all identify themselves as students, while they perceive differently on their racial/ethnic and cultural identity. They have employed a variety of strategies to negotiate with their dynamic, multiple and sometimes contradictory identities when confronted with challenges and opportunities within different social contexts.

Research limitations/implications

The limitations of my study lie first in a small number of participants. Eight Asian American students do not represent the heterogeneous Asian American groups in the USA. More students would provide different perspectives and experiences in the study. The time for conducting this study is another limitation. Longer period on the research sites would provide thicker descriptions.

Practical implications

There are implications for educational practice and future research to help understand the diversity among Asian American students and to find ways to integrate accurate and comprehensive information related to Asian Americans into the curricular with critical reflection upon the issues of race, ethnicity, culture and identity.

Originality/value

This study will enrich the current literature on Asian American education because there is currently limited research in this area. It will give voices to Asian American students and contribute to a better understanding of how both students and teachers are responding to the challenges faced in many schools as demographics change. It will also have implications for teacher education and encourage awareness in this field that might affect future educational practices and policies.

Abstract

Purpose

This paper aims to document the adaptation strategies developed by local farmers to adjust to climate change and related hazards in Lijiang Prefecture in Southwest China, and quantify the determinants of the adaptation measures.

Design/methodology/approach

The study conducted a household survey with 433 respondents in Lijiang to documents adaptation measures. The authors used a multivariate probit model to quantify five categories of adaptation measures against a set of household features, extension and information, resources, social network, financial assets and perception variables.

Findings

The most significant determinants consisted of information on early climate warnings and impending hazards, ownership to land and livestock, irrigation membership in community-based organisations, household savings, cash crop farming and perceptions of climate change and its related hazards. Adaptation strategies and policies highlighting these determinants could help to improve climate change adaptation in the region.

Originality/value

This study quantified the determinants of adaptive strategies and mapped important determinants for the region that will provide farmers with the appropriate resources and information to implement the best practices for adapting to climatic changes. The method and findings could be useful and easily replicable for future agriculture policies.

Abstract

Purpose

This paper aims to present an adaptive fuzzy sliding mode controller with nonlinear observer (AFSMCO) for the redundant robotic manipulator handling a varying payload to achieve a precise trajectory tracking in the task space. This approach could be applied to solve the problems caused by the dynamic effect of the varying payload to robotic system caused by model uncertainties.

Design/methodology/approach

First, a suitable observer using the recursive algorithm is presented for an accurate estimation of external disturbances caused by a variable payload. Second, the adaptive fuzzy logic is designed to approximate the parameters of the sliding mode controller combined with nonlinear observer (SMCO) to avoid chattering in real time. Moreover, Lyapunov theory is applied to guarantee the stability of the proposed closed-loop robotic system. Finally, the effectiveness of the proposed control approach and theoretical discussion are proved by simulation results on a seven-link robot and demonstrated by a humanoid robot platform.

Findings

The varying payload leads to large variations in the dynamics of the manipulator and the tracking error. To achieve high-precision position tracking, nonlinear observer was introduced to feed into the sliding mode control (SMC) which had improved the ability to resist the external disturbance. In addition, the chattering caused by the SMC was eliminated by recursively approximating the switching gain with the usage of adaptive fuzzy logic. Therefore, a distributed control strategy solves the problems of an SMC implementation in improving its tracking performance and eliminating the chattering of the system control.

Originality/value

The AFSMCO is proposed for the first time and used to control the redundant robotic manipulator that handles the varying payload. The proposed control algorithm possesses better robustness and higher precision for the trajectory tracking than classical SMC.

Abstract

Purpose

The purpose of this study is to elucidate the effect of Mn addition on the corrosion behavior of stainless steel.

Design/methodology/approach

Chronoamperometry, quasi-steady-state polarization and electrochemical impedance spectroscopy were used to investigate the corrosion behavior of Mn added A13Cr-HS sample and original S13Cr samples. In addition, the corrosion product film was characterized by a field emission scanning electron microscope equipped with energy-dispersive spectroscopy and X-ray photoelectron spectroscopy.

Findings

The A13Cr-HS sample with 8 wt.% Mn addition maintained good general corrosion resistance in both acidic and alkaline solutions compared to the original S13Cr sample. Additionally, the A13Cr-HS sample had good pitting resistance in an alkaline solution containing Cl, but a weaker resistance in an acidic solution.

Originality/value

The influence of Mn addition on the formation mechanism of the passive film was systematically analyzed.

Abstract

Messrs. W. and G. Clark have invented a milling machine which, it is claimed, for the first time enables a meal containing the whole of the wheat berry in assimilable form to be produced. The cells of the berry, containing the protein, starch grains and wheat germ, are exploded by intense air pressure. The process is wholly dry, whereas wheat which is roller milled is first soaked in water for many hours; and meal produced by the new method contains 8·2 per cent. natural moisture, compared with 17 per cent. in ordinary flour. Already much bread made from the new meal is being sold. It can be obtained from a well‐known London store. Three depôts of the Royal Navy and a London hospital are among regular consumers of bread and biscuits made from the new meal, which is to be subjected to a biological feeding test at the Lister Institute to test its vitamins B1 and B2 complex content.

Abstract

In the year 1900 Koch expressed the view that human and bovine tuberculosis were distinct diseases, that the bacillus of bovine tuberculosis could not produce this disease in the human subject, and that the bacillus of human tuberculosis could not set it up in the bovine species. As is now well known. these conclusions have not received the slightest confirmation from other workers in the same field, and it may be said that the consensus of scientific opinion is now to the effect that the bacilli of human and bovine tuberculosis are identical—at any rate, so far as the effects attributed to them are concerned. The Royal Commission appointed in 1901, and consisting of the late Sir MICHAEL FOSTER, Drs. SIMS WOODHEAD, SIDNEY MARTIN, MACFADYEAN, and BOYCE, have issued a further interim report on their investigations. The first interim report was published in 1904, the conclusions stated in it being to the effect that the human and animal diseases were identical, and that no characteristics by which the one could be distinguished from the other had been discovered. The report now issued shows that these conclusions are confirmed by the results of a very large number of fresh experiments. The main conclusions set forth in the present report are as understated :—

Abstract

Summarizes the literature on mentoring and its effects, pointing out that little research has been done on international mentoring despite globalization. Considers how mentoring could be used to help accountants make international assignments into successful learning experiences and to cope with the culture shock they often report. Discusses the possible role of the mentor before, during and after the assignment, highlighting the critical factors during the process; and compares horizontal and vertical approaches. Urges accounting firms to use mentoring to improve international performance and as a basis for organizational learning in a global environment.

Abstract

At a meeting of the Council of the Royal Borough of Kensington on February 29th, ALDERMAN A. G. McARTHUR, Chairman of the Public Health Committee of the Council, brought up a Report as follows— “We have received replies from nineteen City and Borough Councils to the circular letter addressed to them by this Council protesting against the suggestion made by the Board of Agriculture and Fisheries that, before proceedings under the Sale of Food and Drugs Acts are instituted on analytical evidence in respect of milk there should be a preliminary investigation by an officer of the Local Authority, or that the milk producer should be given an opportunity of offering an explanation.

Abstract

SEPTEMBER is the month when, Summer being irrevocably over, our minds turn to library activities for the winter. At the time of writing the international situation is however so uncertain that few have the power to concentrate on schemes or on any work other than that of the moment. There is an immediate placidity which may be deceptive, and this is superficial even so far as libraries are concerned. In almost every town members of library staffs are pledged to the hilt to various forms of national service—A.R.P. being the main occupation of senior men and Territorial and other military services occupying the younger. We know of librarians who have been ear‐marked as food‐controllers, fuel controllers, zone controllers of communication centres and one, grimly enough, is to be registrar of civilian deaths. Then every town is doing something to preserve its library treasures, we hope. In this connexion the valuable little ninepenny pamphlet issued by the British Museum on libraries and museums in war should be studied. In most libraries the destruction of the stock would not be disastrous in any extreme way. We do not deny that it would be rather costly in labour and time to build it up again. There would, however, be great loss if all the Local Collections were to disappear and if the accession books and catalogues were destroyed.
