Personal reactions to ‘strange’ situations: Attachment styles and acculturation attitudes of immigrants and majority members     

Jan Pieter Van Oudenhoven  Jacomijn Hofstra 《Int J Intercult Relat》2006,30(6):783

A growing number of studies examine the influence of individual factors on acculturation attitudes of immigrants, but few studies focus on majority members’ attitudes. In this paper, two studies are reported on the relation between attachment styles and acculturation attitudes of both immigrants (N=177) and majority members (N=243) in the Netherlands. Until now very few studies have associated cultural adjustment with attachment styles. This is remarkable, because attachment theory refers to interaction with others in new situations. Four different styles of attachment (the secure, dismissing, preoccupied and fearful attachment styles) are related to Berry's classification of acculturation attitudes. People, both immigrants and majority members, with a secure attachment style were positive towards integration, whereas people with a dismissing attachment style were not. Dismissing immigrants were more positive towards separation. Whereas both immigrants and majority members with a secure attachment style showed a similar pattern of correlations between attachment and acculturation, they seem to react quite differently, and even in opposite ways, when they have a preoccupied attachment style. Yet, the different reactions may be caused by the same psychological process: The existential ambivalence of preoccupied people may lead to diverse reactions.  相似文献   

Spread or Sacrifice: Dilemma for Lighting Policies     

Agnes Brokerhof  Pieter Kuiper  Steph Scholten 《文物保护研究》2018,63(5):28-34

ABSTRACT

Light sensitive objects will fade on display. Collection managers and curators face the dilemma whether to spread fading over several similar objects or sacrifice one. This paper describes an experiment in which participants were asked how they would want to pass on a collection of seventeenth century hand-coloured maps to coming generations. Results show that while colour changes are hardly visible, both public and professionals do not perceive them as damage and prefer to spread fading. Once fading becomes clearly visible in all maps, the preference shifts to sacrificing one map. The tipping point lies around five just noticeable changes. This information can be used when selecting objects for exhibition. The outcome also implies it would be prudent to assess the degree of fading of much exhibited objects and consider whether and when to choose for a sacrifice strategy.  相似文献   

Hybrid capillary-inserted microfluidic device for sheathless particle focusing and separation in viscoelastic flow     

Jeonghun Nam  Justin Kok Soon Tan  Bee Luan Khoo  Bumseok Namgung  Hwa Liang Leo  Chwee Teck Lim  Sangho Kim 《Biomicrofluidics》2015,9(6)

A novel microfluidic device which consists of two stages for particle focusing and separation using a viscoelastic fluid has been developed. A circular capillary tube was used for three-dimensional particle pre-alignment before the separation process, which was inserted in a polydimethylsiloxane microchannel. Particles with diameters of 5 and 10 μm were focused at the centerline in the capillary tube, and the location of particles was initialized at the first bifurcation. Then, 5 and 10 μm particles were successfully separated in the expansion region based on size-dependent lateral migration, with ∼99% separation efficiency. The proposed device was further applied to separation of MCF-7 cells from leukocytes. Based on the cell size distribution, an approximate size cutoff for separation was determined to be 16 μm. At 200 μl/min, 94% of MCF-7 cells were separated with the purity of ∼97%. According to the trypan blue exclusion assay, high viability (∼90%) could be achieved for the separated MCF-7 cells. The use of a commercially available capillary tube enables the device to be highly versatile in dealing with particles in a wide size range by using capillary tubes with different inner diameters.  相似文献   

Taking the grading leniency story to the edge. The influence of student, teacher, and course characteristics on student evaluations of teaching in higher education     

Bert Brockx  Pieter Spooren  Dimitri Mortelmans 《Educational Assessment, Evaluation and Accountability》2011,23(4):289-306

The use of student evaluation of teaching (SET) to evaluate and improve teaching is widespread amongst institutions of higher education. Many authors have searched for a conclusive understanding about the influence of student, course, and teacher characteristics on SET. One hotly debated discussion concerns the interpretation of the positive and statistically significant relationship that has been found between course grades and SET scores. In addition to reviewing the literature, the main purpose of the present study is to examine the influence of course grades and other characteristics of students, courses, and teachers on SET. Data from 1244 evaluations were collected using the SET-37 instrument and analyzed by means of cross-classified multilevel models. The results show positive significant relationships between course grades, class attendance, the examination period in which students receive their highest course grades, and the SET score. These relationships, however, are subject to different interpretations. Future research should focus on providing a definitive and empirically supported interpretation for these relationships. In the absence of such an interpretation, it will remain unclear whether these relationships offer proof of the validity of SET or whether they are a biasing factor.  相似文献   

Minimax optimal control of linear system with input-dependent uncertainty     

Changzhi Wu  Kok Lay Teo  Xiangyu Wang 《Journal of The Franklin Institute》2014

In this paper, the quadratic minimax optimal control of linear system with input-dependent uncertainty is studied. We show that it admits a unique solution and can be approximated by a sequence of finite-dimensional minimax optimal parameter selection problems. These finite-dimensional minimax optimal parameter selection problems are further reduced to scalar optimization problems which also admit unique solutions. Thus, the original minimax optimal control problem is solved via solving a sequence of simple scalar optimization problems. Numerical experiments are presented to illustrate the developed method.  相似文献

Content integration as a factor in math-game effectiveness     

Sylke Vandercruysse  Judith ter Vrugte  Ton de Jong  Pieter Wouters  Herre van Oostendorp  Lieven Verschaffel  Jan Elen 《Educational technology research and development : ETR & D》2017,65(5):1345-1368

In this study we focus on the integration of mathematical learning content (i.e., proportional reasoning) in game-based learning environments (GBLE). More specifically, two kinds of GBLEs are set up: an extrinsically integrated GBLE and an intrinsically integrated GBLE. In the former environment, the mathematical content is not part of the core mechanics and structure of the gaming world. In the latter environment, the mathematical content is delivered through the parts of the game that are the most fun to play and embodied within the structure of the gaming world and the players’ interactions with it. Sixty-four vocational track students participated in the study, all of them working in either version of the self-developed GBLE “Zeldenrust”. The results of this study suggest that the way the content is integrated in a GBLE (i.e., intrinsically or extrinsically) matters: contrary to our expectations, students who played the extrinsically integrated game showed higher learning gains, motivational gains and perceived usefulness than students who played the game in which the content was intrinsically integrated.  相似文献

Predicting multicultural effectiveness of international students: the Multicultural Personality Questionnaire     

Jan Pieter Van Oudenhoven  Karen I. Van der Zee 《Int J Intercult Relat》2002,26(6)

The present study considered the reliability and validity of the 78-item revised version of the Multicultural Personality Questionnaire, a multidimensional instrument aimed at measuring multicultural effectiveness of expatriate employees and students. The questionnaire includes scales for cultural empathy, open-mindedness, emotional stability, social initiative and flexibility. Participants were native and foreign students of an international business school (N=171) in the Netherlands. The MPQ scales appeared to be more strongly predictive of adjustment of international students as compared to native students. Moreover, the instrument was able to explain variance in students’ adjustment beyond self-efficacy.  相似文献   

School‐to‐work transition services for students with disabilities in Malaysia: organisations' views on policy and practices     

Melissa Ng Lee Yen Abdullah  See Ching Mey  Tan Kok Eng  Rosly Othman  Ahmad Fairuz Omar 《Journal of Research in Special Educational Needs》2013,13(4):259-271

Transition services are required by law for students with disabilities in many developed countries. In Malaysia, however, there is still no specific legislation mandating that school‐to‐work transition planning and services be provided to students with disabilities. This study investigated the state of the transition services provided by educational organisations to students with disabilities in Malaysia. A mixed method research design, which utilises both quantitative and qualitative research techniques, was employed to obtain information from 23 government organisations and NGOs involved in the education and training of students with disabilities. This study found that the organisations surveyed were aware of the lack of transition support and call attention to the importance of instituting a national policy on school‐to‐work transition services and supported employment systems for students with disabilities. The legislative and educational implications for Malaysia are discussed.  相似文献
