Governance and success of university-industry collaborations on the basis of Ph.D. projects : an explorative study

Faced with ever-increasing pressure to innovate and perform, firms consider universities as a significant, external source of knowledge. There is a variety of ways through which such knowledge flow can take place, including academic publications, contract research, staff mobility and university patents and licenses, but also more collaborative modes such as joint research projects. This paper focuses on a specific – and promising – collaborative model, in which firms and universities are together involved in a Ph.D. project, carried out by a doctoral candidate. We model the relationship on the one hand on various aspects of governance, and the success of the collaboration on the other. Here, success is operationalized in a number of different ways, including the successful transfer, the application and the commercialization of knowledge. Our model was tested using a survey conducted at the Eindhoven University of Technology. We conclude that governance decisions have a significant impact on the ultimate success. Among other things, the choice of university supervisor plays a pivotal role. Moreover, success is more likely if there is joint decision-making by both university and partner on the content of the project, and communication between the Ph.D. candidate and their supervisor in the firm has a high frequency and quality. We believe our findings can help universities and firms to collaborate successfully

Haematologic indices in pesticides factory workers

The purpose of this study was to evaluate the effect of pesticides on blood indices of subjects which are exposed to organophosphate toxins. This research was a cohort study which was carried out during 2005 on the employee of a pesticide factory in Golestan province (North of Iran). In this study the sampling from 63 subjects was carried out for two sessions in days 1 and 90. CBC and hematologic indices performed by cell counter instrument. The mean of MCV in phase 1 was 82.8±7.1 fl and in second phase the MCV was 80.3±6.7 fl. This drop in MCV statistically was meaningful (paired t-test, mean = 2.5, 95% CI=2.0-2.9, p<0.001). Erythrocyte number, hemoglobin, HCT and MCHC increase in second phase compared to first phase statistically was meaningful. There was not any significant relation between the place of work and variation of red blood cell indices. In regard to the changes in hematologic indices in workers of pesticide factory in a three months period, it seems logical to set up a program to have a routine check on the hematologic indices in working personal engaging in such occupations. © 2007 Asian Network for Scientific Information

Remediasi Miskonsepsi Siswa pada Konsep Asam dan Basa dengan Menggunakan Strategi Konflik Kognitif di Kelas XII MIA MAN 1 Kota Gorontalo

Penelitian ini bertujuan untuk meremediasi miskonsepsi siswa dengan menggunakan strategi konflik kognitif. Desain penelitian ini yaitu one group pretest posttest. Sampel pada penelitian ini berjumlah 95 siswa yang terbagi dalam tiga kelas. Data pada penelitian ini berupa data kuantitatif dan kualitatif. Tes pemahaman konsep yang diberikan berupa three-tier diagnostic test yang sudah di uji validatas dan relibilitas. Tes yang digunakan sudah dinyatakan valid oleh tim validator dengan kategori timggi (baik) realibilitas r = 0,88 (kategori tinggi) . Analisis data menggunakan uji Wilcoxon signed-rank test dengan taraf signifikasi α= 0,05 untuk melihat pergeeran miskonsepsi, uji Liliefors umuk menguji keterlaksanaan sintak. Penentuan kategori tingkat pemahaman siswa untuk mengidentifikasi konsepsi siswa digunakan pilihan ganda tiga tingkat (three- tier diagnostic test) yang dilengkapi dengan Certainty of Response Index (CRI). Certainty Of Response (CRI). Hasil uji Wilcoxon signed-rank test menunjukkan bahwa pada taraf signifikansi α= 0,05 memberikan hasil pada ketiga kelas secara individu masing-masing berada pada nilai 0,000 dan secara klasikal berada pada nilai 0,002; 0,002 dan 0,002. Ini menunjukkan bahwa α -value yang diperoleh lebih kecil dari 0,05 sehingga H0 ditolak dan H1 diterima. Artinya, strategi konflik dapat mereduksi miskonsepsi siswa pada konsep larutan asam basa

Sintesis dan Karakterisasi Carboxymethyl Cellulose Sodium (Na-CMC) dari Selulosa Eceng Gondok (Eichhornia crassipes) dengan Media Reaksi Etanol-Isobutanol

Eceng gondok adalah salah satu tumbuhan bahan serat alam yang memiliki kandungan selulosa yang cukup tinggi. Kadar selulosa yang tinggi dapat digunakan dalam pembuatan Karboksimetil Selulosa Sodium (Na-CMC). Tujuan dari penelitian ini adalah: untuk mengetahui karakteristik Karboksimetil Selulosa Sodium (Na-CMC) dari tanaman eceng gondok. dan mendapatkan variasi media reaksi terbaik dalam proses sintesis. Penelitian ini terdiri dari tiga tahap yaitu tahap pertama ekstraksi selulosa yang terdiri dari (dewaxing, dehemisellulose dan bleaching), tahap kedua yaitu tahap sintesis yang terdiri dari tahap pencampuran menggunakan media reaksi etanol-isobutanol (20:80, 50 : 50, 80:20). Tahap alkalisasi menggunakan NaOH 10% b / v, tahap karboksimetilasi menggunakan ClCH2COONa. Tahap ketiga adalah karakterisasi CMC yang terdiri dari uji organoleptik, sifat fisikokimia (pH, susut pengeringan sampel, viskositas dan derajat substitusi), uji kadar NaCl, uji kemurnian, analisis FT-IR. Berdasarkan hasil penelitian didapatkan bahwa karakteristik CMC mendekati karakteristik standar Na-CMC dengan campuran media reaksi etanol-isobutanol 20:80 (v / v) dengan nilai DS 0,8560, kemurnian 93,7463% level, pH 6,5 dan viskositas. 302 cP

Pelatihan Pembuatan Produk berbasis Jantung Pisang pada Ibu-Ibu PKK dan Dasa Wisma Desa Dutohe Barat

West Dutohe Village is located in Kabila District, Bone Bolango Regency, Gorontalo Province, has a plantation area that is generally planted with banana trees so that it becomes a superior commodity for the village community. Banana liver was chosen as a product because of its very abundant availability in the village of West Dutohe. The PKK consists of 30 people who are interested in becoming entrepreneurs, but due to lack of direction and training, this business group is less productive in producing products that are worth selling. The absence of innovation in processing technology into various processed banana heart products of economic value such as sausages, meatballs, nuggets, and shredded banana liver is constrained by lack of knowledge and motivation. The Community Service Program in West Dutohe village aims to increase the motivation of mothers to become independent entrepreneurs through appropriate technology in the field of banana liver-based food processing. Training methods for processing various food products based on banana liver such as sausages, meatballs, and nuggets. The implementation of activities in training on production and innovation of banana liver-based products is very cooperative between trainers and partners, especially PKK mothers. The insights of partners and village officials are open and eager for the continuation of this program in the village of West Dutohe. The advantages of various liver-based processed products are very powerful because there is nothing similar in other areas so this product can create a novelty and culinary peculiarity in the western Village of Dutoh
