Realisation of University-Industry Collaboration through Industry-Based Learning at Indonesian Higher Education

The collaboration between universities and industries has become increasingly important for the development of Science and Technology. This is particularly more prominent in the Science Technology Engineering and Mathematics (STEM) disciplines. Literature suggest that the key element of University-Industry Partnership (UIP) is the exchange of knowledge that is mutually beneficial for both parties. One real example of the collaborations is Industry-Based Learning (IBL) in which university students are coming into industries to experience and learn how the skills and knowledge acquired in the classroom are implemented in work places. This paper investigate how the University-Industry Collaboration program is implemented though Industry-Based Learning (IBL) at Indonesian Universities. The research findings offer useful insights and create a new knowledge in the field of STEM education and collaborative learning. The research will contribute to existing knowledge by providing empirical understanding of this topic. The outcomes can be used to improve the quality of University-Industry Partnership programs at Indonesian Universities and inform Indonesian higher education authorities and their industrial partners of an alternative approach to enhance their IBL programs.

Interplay of Virulence Factors in Complement Resistance of Streptococcus pneumoniae

Streptococcus pneumoniae (pneumococcus) is a normal inhabitant of the human nasopharynx. Symptoms occur in only a small proportion of those who become carriers, but the ubiquity of the organism in the human population results in a large burden of disease. S. pneumoniae is the leading bacterial cause of pneumonia, sepsis, and meningitis worldwide, causing the death of a million children each year. Middle-ear infection is the most common clinical manifestation of mucosal pneumococcal infections. In invasive disease, S. pneumoniae gains access to the bloodstream and spreads to normally sterile parts of the body. The progression from asymptomatic colonization to disease depends on factors characteristic of specific pneumococcal strains as well as the status of host defenses. The polysaccharide capsule surrounding the bacterium is considered to be the most important factor affecting the virulence of pneumococci. It protects pneumococci from phagocytosis and also may determine its affinity to the respiratory epithelium. S. pneumoniae as a species comprises more than 90 different capsular serotypes, but not all of them are equally prevalent in human diseases. Invasive serotypes are rarely isolated from healthy carriers, but relatively often cause invasive disease. Serotypes that are carried asymptomatically for a long time behave like opportunistic pathogens, causing disease in patients who have impaired immune defenses. The complement system is a collection of blood and cell surface proteins that act as a major primary defense against invading microbes. Phagocytic cells with receptors for complement proteins can engulf and destroy pneumococcal cells opsonized with these proteins. S. pneumoniae has evolved a number of ways to subvert mechanisms of innate immunity, and this is likely to contribute to its pathogenicity. The capsular serotype, proteins essential for virulence, as well the genotype, may all influence the ability of pneumococcus to resist complement and its potential to cause disease. Immunization with conjugate vaccines produces opsonic antibodies, which enhance complement deposition and clearance of the bacteria. The pneumococcal vaccine included in the Finnish national immunization program in 2010 contains the most common serotypes causing invasive disease. Clinical data suggest that protection from middle-ear infection and possibly also from invasive disease depends largely on the capsular serotype, for reasons hitherto unknown. The general aim of this thesis is to assess the relative roles of the pneumococcal capsule and virulence proteins in complement evasion and subsequent opsonophagocytic killing. The main question is whether differences between serotypes to resist complement explain the different abilities of serotypes to cause disease. The importance of particular virulence factors to the complement resistance of a strain may vary depending on its genotype. Prior studies have evaluated the effect of the capsule and virulence proteins on complement resistance of S. pneumoniae by comparing only a few strains. In this thesis, the role of pneumococcal virulence factors in the complement resistance of the bacterium was studied in several genotypically different strains. The ability of pneumococci to inhibit deposition of the complement protein C3 on the bacterial surface was found to depend on the capsular serotype as well as on other features of the bacteria. The results suggest that pneumococcal histidine triad (Pht) proteins may play a role in complement inhibition, but their contribution depends on the bacterial genotype. The capsular serotype was found to influence complement resistance more than the bacterial genotype. A higher concentration of anticapsular antibodies was required for the opsonophagocytic killing of serotypes resistant to C3 deposition. The invasive serotypes were more resistant to C3 deposition than the opportunistic serotypes, suggesting that the former are better adapted to resist immune mechanisms controlling the development of invasive disease. The different susceptibilities of serotypes to complement deposition, opsonophagocytosis, and resultant antibody-mediated protection should be taken into account when guidelines for serological correlates for vaccine efficacy evaluations are made. The results of this thesis suggest that antibodies in higher quantity or quality are needed for efficient protection against the invasive serotypes.

Intraperitoneal injection of extracted microcystins results in hypovolemia and hypotension in crucian carp (Carassius auratus)

Circulatory responses of crucian carp injected intraperitoneally with extracted micro-cystins (MCs) were studied at sublethal and lethal doses (150 and 600 mu g MC kg(-1) body mass, respectively). Mean arterial blood pressure (MAP), heart rate, hematocrit (Hct), red blood cell (RBC) counts, and circulating blood volume (BV) were assayed at 0, 1, 3, 12, 24, and 48 h post-toxin administration. MAP decreased significantly in a dose-dependent manner over time. Within the 48-h test period, the lethal dose as well as the sublethal dose resulted in a steady decline of MAP without recovery. Heart rate significantly increased within 24 h post-injection as blood pressure significantly dropped, then showed a terminal decline to the control level. The dose-dependent decreases in BV and Hct were directly related to the drop in MAP. Intraperitoneal injection of a lethal dose of MCs led to hepatic and gill hemorrhage. Consequently, crucian carp given MCs suffered from hypovolemic hypotensive shock. (C) 2009 Elsevier Ltd. All rights reserved.

Changes in plasma thyroid hormones and cortisol levels in crucian carp (Carassius auratus) exposed to the extracted microcystins

The endocrine response of crucian carp injected intraperitoneally with extracted microcystins (MC) was investigated in this study. Fish were injected intraperitoneally either with 0.75% NaCl (control) and Microcystis extract corresponding to 150 and 600 mu g microcystins per kg body weight. The plasma levels of triiodothyronine (T-3), thyroxine (T-4), free triiodothyronine (FT3), free thyroxine (FT4), and cortisol were determined at 0, 1, 3, 12, 24. and 48 h post-administration of MC-containing extract. Treated fish displayed abnormal behaviors, Such as a startle response and disoriented swimming, as well as changes in ventilation rates. Plasma cortisol concentrations of fish in both dose groups significantly increased after administration of extracted MC and remained high throughout the experiment, which suggested that MC elicited a stress response in treated fish. The profiles of cortisol changes in treated fish appeared to be dose dependent, indicating that fish in the high dose group experienced greater MC-incluced disturbance. Mortality occurred after 12 h in the high dose group. Plasma levels of T-4, T-3, FT4, and FT3 did not vary significantly between the control fish. In contrast to this, fish exposed to MC-containing extract showed significant declines in T-3, FT4, and FT3 levels in a dose-depenclent manner throughout the experiment. Plasma T4 levels, however, did not vary significantly in the low dose group, whereas they decreased significantly it 48 h post injection in the high dose group. This study demonstrates that administration of microcystins-containing extract causes a stress response and reduces the plasma levels of thyroid hormones in crucian carp. These results illustrate that microcystins exerted potent effects on the endocrine system of crucian carp, through activating their hypothalamus-pituitary- interrenal axis and disturbing thyroid function.

Narrowing of band gap and low-temperature spin glass behavior of FeNi co-doped ZnO nanowires

This letter reports on the Raman, optical and magnetic properties of FeNi co-doped ZnO nanowires prepared via a soft chemical solution method. The microstructural investigations show that the NiFe co-dopants are substituted into wurtzite ZnO nanostructure without forming any secondary phase. The co-doped nanowires show a remarkable reduction of 34 nm (267.9 meV) in the optical band gap, while suppression in the deep-level defect transition in visible luminescence. Furthermore, these nanowires exhibit ferromagnetism and an interesting low-temperature spin glass behavior, which may arise due to the presence of disorder and strong interactions of frustrated spin moments of Ni and Fe co-dopants on the ZnO lattice sites.

Numerical analysis for four-wave mixing based wavelength conversion of differential phase-shift keying signals

We numerically investigate the main constrains for high efficiency wavelength conversion of differential phase-shift keying (DPSK) signals based on four-wave mixing (FWM) in highly nonlinear fiber (HNLF). Using multi-tone pump phase modulation techniques, high efficiency wavelength conversion of DPSK signals is achieved with the stimulated Brillouin scattering (SBS) effects effectively suppressed. Our analysis shows that there is a compromise between conversion efficiency and converted idler degradation. By optimizing the pump phase modulation configuration, the converted DPSK idler's degradation can be dramatically decreased through balancing SBS suppression and pump phase modulation degradation. Our simulation results also show that these multi-tone pump phase modulation techniques are more appropriate for the future high bit rate systems.

Social development of primary aged children through a movement education program

Unique in Canada, is a university based movement program offered to children aged 1-12 which is diverse and inclusive in its design to foster healthy physical, cognitive, affective and social development. The purpose of this study is to investigate how children's involvement in a weekly movement education program influences their social development. The primary-aged children involved in this research are participants in the university based Saturday morning program, The Children's Movement Program (CMP), in which creative dance, educational gymnastics and developmental games are employed to enhance optimal development. The 15 participants were systematically observed for 8 weeks as they naturally engaged in the program's activities. Interviews were conducted with both children and their caregivers throughout the duration of the program. Particular attention was paid to the perceptions of caregivers regarding the advantages of a program based upon principles of movement education. Results indicate that participation in the program increases children's opportunity to interact socially and address ways in which program content, pedagogy and context encourage social development. A figure was developed with these components to assist teachers in creating inclusive and meaningful movement experiences. 'Content' is referred to as the material to be learned or the desired outcome for the learner. 'Pedagogy' refers to the process in which the student will engage and 'Context' refers to the environment in which the experience occurs (eg. skating rink with playground balls). It is recommended that each is thoroughly addressed individually for its potential in lesson design.

Mercado laboral calificado en Colombia: Estudio sobre el desequilibrio entre oferta y demanda de trabajo para los años 2020 y 2030

El propósito básico de esta investigación es identificar los desajustes (déficits o superávits) no estructurales entre la oferta y demanda de trabajo en Colombia para los años 2020 y 2030, así como interpretar los hallazgos y proponer elementos de estrategia para las empresas a fin de mitigar los efectos adversos del desajuste sobre su capacidad para atraer y retener talento. El argumento central del proyecto consiste en sostener que en un escenario no mayor a los 10 años la oferta de trabajo calificado en Colombia no será suficiente para (i) equilibrar el mercado y (ii) atender la demanda agregada de trabajo, debido a los cambios generacionales en la realidad demográfica del país, el bajo nivel de preparación de la fuerza laboral disponible y los altos índices de informalidad de los trabajadores y las empresas. Dentro de los resultados se presenta una proyección del comportamiento del mercado de trabajo, así como la magnitud del desequilibrio entre los agentes del mercado. Este estudio aplicado es una propuesta cuantitativa de aproximación a la crisis de talento que se revisa en otros estudios. Es un precedente sólido para profundizar con otros enfoques el futuro del trabajo en Colombia.

Divergence Involving Global Regulatory Gene Mutations in an Escherichia coli Population Evolving under Phosphate Limitation

Many of the important changes in evolution are regulatory in nature. Sequenced bacterial genomes point to flexibility in regulatory circuits but we do not know how regulation is remodeled in evolving bacteria. Here, we study the regulatory changes that emerge in populations evolving under controlled conditions during experimental evolution of Escherichia coli in a phosphate-limited chemostat culture. Genomes were sequenced from five clones with different combinations of phenotypic properties that coexisted in a population after 37 days. Each of the distinct isolates contained a different mutation in 1 of 3 highly pleiotropic regulatory genes (hfq, spoT, or rpoS). The mutations resulted in dissimilar proteomic changes, consistent with the documented effects of hfq, spoT, and rpoS mutations. The different mutations do share a common benefit, however, in that the mutations each redirect cellular resources away from stress responses that are redundant in a constant selection environment. The hfq mutation lowers several individual stress responses as well the small RNA-dependent activation of rpoS translation and hence general stress resistance. The spoT mutation reduces ppGpp levels, decreasing the stringent response as well as rpoS expression. The mutations in and upstream of rpoS resulted in partial or complete loss of general stress resistance. Our observations suggest that the degeneracy at the core of bacterial stress regulation provides alternative solutions to a common evolutionary challenge. These results can explain phenotypic divergence in a constant environment and also how evolutionary jumps and adaptive radiations involve altered gene regulation.

A democratização do acesso ao ensino superior: um estudo sobre o Programa Universidade Para Todos (PROUNI) e sobre o sistema de reservas de cotas de vagas étnico-raciais

Brazil is an extremely unequal country and this inequality has been a permanent characteristic of its economic and social structure. Some scholars generally consider that the economic growth has generated extreme conditions of space and social inequalities, which reveal themselves within Brazil¿s regions, states, rural and urban areas, central and peripheral areas and among its ethnic groups. Such conditions negatively affect the quality of life of the population and will be reflected in the reduction of life expectancy, in the increase of the indexes of infant mortality and illiteracy, amongst other aspects. Education is considered one of the ways to promote the development of a country, however, access to education, specially higher education in Brazil, since it was first implemented, had been limited to a small group of privileged people, the elite of society. Thus, it becomes necessary to extend the access of students to higher education and consequently to generate individuals capable of changing the reality of the place where they live in and as a result, to develop the country. The purpose of this research is to analyze two programs destined to the amplify the access to higher education in Brazil, namely, the University for All Program (ProUni) and the System of Quotas, with the objective to verify at which level their drawings and strategies will allow the democratization of the access to higher education and the reduction of regional inequalities. In order to achieve its objective, the study is initiated with the issue of development and inequalities in Brazil, then it goes through the history of higher education in Brazil and it is finished with the analysis of ProUni and the System of Quotas.

O acesso à educação superior pelas populações do campo, na universidade pública: um estudo do PRONERA, PROCAMPO e PARFOR, na Universidade Federal do Pará

O presente estudo foca a temática do acesso das populações do campo à universidade pública, com base na análise do PRONERA – Programa Nacional de Educação na Reforma Agrária, do PROCAMPO – Programa de Apoio à Formação Superior em Licenciatura em Educação do Campo e do PARFOR – Plano Nacional Formação de Professores da Educação Básica, tomando como referência a Universidade Federal do Pará. A pesquisa analisa o cenário da Educação Superior e as modificações no sistema de acesso à universidade, apresenta um panorama sobre as iniciativas de acesso das populações do campo, analisando cursos, recursos financeiros, dados estatísticos e apresentando uma cartografia dos programas no Brasil e no Estado do Pará. Para alcançar o objetivo geral, que foi de analisar as formas de acesso pela população do campo à Educação Superior, no período pós Lei 9.394/96, optou-se por uma metodologia de abordagem dialética, buscamos analisar fatores sociais, políticos, econômicos e as relações estabelecidas, no contexto do acesso das populações do campo à educação superior. Convém esclarecer que não tomamos o método dialético por excelência, pois consideramos que existem muitos elementos dele que não poderão ser aplicados por nós no tempo que a pesquisa propõe, uma vez que somente essa perspectiva nos permitiria a análise da realidade em questão, buscando o apoio na exploração de bibliografias e na técnica de análises de documentos, para posterior sistematização, organização e análise dos dados estatísticos e das informações coletadas ao longo da pesquisa. Os resultados da investigação apontam para um novo eixo de análise dentro da temática Educação Superior – a Educação Superior do Campo, uma vez que o acesso das populações do campo, com metodologias diferenciadas e pautadas no referencial da Educação do Campo passou a ser uma realidade em nosso País. A pesquisa aponta ainda a ampliação do acesso às universidades públicas, com base nos princípios conquistados pela luta dos movimentos sociais e do movimento por uma educação do campo, assim como identificou outras particularidades que não condizem, a princípio, com o que seria uma política educacional voltada para o campo, como é o caso do PARFOR, que, embora não seja criado propriamente a atender estudantes do campo, tem, no Pará, contemplado uma significativa parcela de estudantes/ educadores atuantes em escolas do campo.

Use of policy, education, and enforcement to reduce binge drinking among university students: The NU Directions project

This paper describes a program, conducted over a 5-year period, that effectively reduced heavy drinking and alcohol-related harms among university students. The program was organized around strategies to change the environment in which binge drinking occurred and involved input and cooperation from officials and students of the university, representatives from the city and the neighborhood near the university, law enforcement, as well as public health and medical officials. In 1997, 62.5% of the university’s approximately 16,000 undergraduate student population reported binge drinking. This rate had dropped to 47% in 2003. Similar reductions were found in both self-reported primary and secondary harms related to alcohol consumption.

Assessment of in vivo genotoxicity of the rodent carcinogen furan: evaluation of DNA damage and induction of micronuclei in mouse splenocytes

In recent years, several surveys have highlighted the presence of the rodent carcinogen furan in a variety of food items. Even though the evidence of carcinogenicity of furan is unequivocal, the underlying mechanism has not been fully elucidated. In particular, the role of genotoxicity in furan carcinogenicity is still not clear, even though this information is considered pivotal for the assessment of the risk posed by the presence of low doses of furan in food. In this work, the genotoxic potential of furan in vivo has been investigated in mice, under exposure conditions similar to those associated with cancer onset in the National Toxicology Program long-term bioassay. To this aim, male B6C3F1 mice were treated by gavage for 4 weeks with 2, 4, 8 and 15 mg furan/kg b.w./day. Spleen was selected as the target organ for genotoxicity assessment, in view of the capability of quiescent splenocytes to accumulate DNA damage induced by repeat dose exposure. The induction of primary DNA damage in splenocytes was evaluated by alkaline single-cell gel electrophoresis (comet assay) and by the immunofluorescence detection of foci of phosphorylated histone H2AX (gamma-H2AX). The presence of cross-links was probed in a modified comet assay, in which cells were irradiated in vitro with gamma-rays before electrophoresis. Chromosome damage was quantitated through the detection of micronuclei in mitogen-stimulated splenocytes using the cytokinesis-block method. Micronucleus induction was also assessed with a modified protocol, using the repair inhibitor 1-beta-arabinofuranosyl-cytosine to convert single-strand breaks in micronuclei. The results obtained show a significant (P < 0.01) increase of gamma-H2AX foci in mitogen-stimulated splenocytes of mice treated with 8 and 15 mg furan/kg b.w. and a statistically significant (P < 0.001) increases of micronuclei in binucleated splenocytes cultured in vitro. Conversely, no effect of in vivo exposure to furan was observed when freshly isolated quiescent splenocytes were analysed by immunofluorescence and in comet assays, both with standard and radiation-modified protocols. These results indicate that the in vivo exposure to furan gives rise to pre-mutagenic DNA damage in resting splenocytes, which remains undetectable until it is converted in frank lesions during the S-phase upon mitogen stimulation. The resulting DNA strand breaks are visualized by the increase in gamma-H2AX foci and may originate micronuclei at the subsequent mitosis.
