    No full text
    Kajian ini adalah berkenaan dengan salah satu jenis persatuan sukarela orang Cina di Seremban, iaitu persatuan yang berasaskan dialek. Bab pertama menyentuh bidang dan tujuan kajian serta metodologi kajian yang meliputi kerja luar dan cara-cara pengutipan data, sifat soal-selidik dan jenis sampling. Ciri-ciri responden, sumber data tambahan dan amsalah serta kelemahan kajian juga dikemukakan. Satu tinjauan sejarah mengenai masyarakat Cina dan persatuan sukarela mereka akan ditinjau dalam bab kedua. Aspek-aspek masyarakat Cina yang dikaji termasuklah sebab-sebab yang membawa kepada penghijrahan mereka ke rantau ini, pembahagian mereka mengikut kumpulan dialek tertentu dan daerah asal mereka serta demografi, pola pertempuan dan pekerjaan mereka di Malaysia. Asal-usul dan sejarah perkembangan persatuan sukarela serta struktur organisasi persatuan dialek juga akan dikaji. Bab tiga merupakan Analisa data tentang perkembangan Persatuan Keng Chew Negeri Sembilan sebelum tahun 1945, yang diperolehi dari penyelidikan luar. Aspek-aspek yang dikaji ialah latarbelakang sejarah, prinsip penubuhan, objektif, perlembagaan dan peraturan, keahlian dan fungsi persatuan. Keadaan persatuan semasa Perang Dunia Kedua juga ditinjau dalam bab ini

    Making sense of students’ errors in solving problems related to measures of dispersion

    The importance of statistical learning has been widely discussed. However, little effort has been made to understand the difficulties of students in learning measure of dispersion, which is the key component to statistical learning. The present study sought to identify the reasons behind the errors committed in solving problems related to measures of dispersion, by examining students’ errors in the diagnostics tests, followed by in depth interviews to elicit their thinking and understanding. There were 85 grade-11 high school students involved in the first phase of the quantitative research and 10 students with weak performance were subsequently selected for the second phase qualitative research. The interviews were conducted using the contingent teaching model. The findings indicated that students’ committing errors in solving problems related to measure of dispersion due to lacking statistical vocabulary knowledge, weak symbol sense, rote learning, low statistical reasoning and statistical thinking ability. The results of the study and proper remedials are discussed

    Cell adhesion molecules are ubiquitous in multicellular organisms, specifying precise cell-cell interactions in processes as diverse as tissue development, immune cell trafficking and the wiring of the nervous system(1-4). Here we show that a wide array of synthetic cell adhesion molecules can be generated by combining orthogonal extracellular interactions with intracellular domains from native adhesion molecules, such as cadherins and integrins. The resulting molecules yield customized cell-cell interactions with adhesion properties that are similar to native interactions. The identity of the intracellular domain of the synthetic cell adhesion molecules specifies interface morphology and mechanics, whereas diverse homotypic or heterotypic extracellular interaction domains independently specify the connectivity between cells. This toolkit of orthogonal adhesion molecules enables the rationally programmed assembly of multicellular architectures, as well as systematic remodelling of native tissues. The modularity of synthetic cell adhesion molecules provides fundamental insights into how distinct classes of cell-cell interfaces may have evolved. Overall, these tools offer powerful abilities for cell and tissue engineering and for systematically studying multicellular organization.
