How Can Innovative Practices In HEIs Facilitate Sustainable Social And Economic Development ?
No full textThe paper is focused on analyzing net-based practices in Higher Education Institutions (HEIs) as a policy tool for instituting a sustainable social and economic development. The purpose of the study is to identify relationships between net-based HEIs and welfare perspective; to investigate the extent to which the use of innovative education can affect societies. The paper challenging the argument HEIs that perform badly have a significant negative impact on economic and social growth. The main challenge is to identify the technical, economical and social aspects of HEIs as indicators of this impact, to consider outcomes for stakeholders of society. The research draws upon E-learning as mostly effective means of reducing cost of educational services of HEIs, aims to summarize the main findings of the scientific findings. The case studies show how the effectiveness of using net learning in HEIs can lead to social and economic growth in the countries concerned. Of particular importance are the differences between developed and developing countries. Upon the examination it becomes clear that E-skills have become the effective way to overcome differences among human, social capitals of countries by significant positive effect on wage levels. Trough showing the productivity paradox in innovative HEIs the paper tries to explain divides between counties, the importance of new policies in HEIs for governments. This research will provide valuable information regarding public regional decision-making in establishing organizational structures for efficiency (social benefits) of lifelong learning, provides novel insight into the understanding of E-education becoming the benchmark for HEIs and global economies.Technology, Policy and Managemen
Synthèse de régioisomères de cyclodextrines tripontées : étude de la déformation de cavités
No full textThe use of macrocycles in molecular recognition or in catalysis aroused great interest over the past few years. The study of the formation of inclusion complexes with inherently chiral macrocycles allows the recognition of small chiral molecules which can be more or less specific. The use of cyclodextrins, which are already chiral due to the presence of D-glucose units allows the formation of diastereomeric inclusion complexes. In the last few years, the structural modification of cyclodextrins by bridging gave access to distorted cavities. This distortion led to good results and resulted in an increase of the selectivity offered by the cavity in asymmetric catalysis. In order to create new cavity shapes to increase the selectivity, different regioisomers of tri-bridged cyclodextrins have been synthesized. To characterize the distortion, complexation of metals encapsulated inside the cavity have been achieved. We were able to show that the two regioisomeric patterns had a pseudo-enantiomeric relationship. The synthesis of an encapsulated superbase has also been done in order to test the ability of the two regioisomers to induce a selectivity in asymmetric catalysis.L'utilisation de macrocycles en reconnaissance moléculaire ou en catalyse a suscité un grand intérêt ces dernières années.

Impact of HEIs on the Scottish economy: new evidence from an HEI-disaggregated input-output approach
No full textThis paper measures the regional demand impacts on output and employment of Scottish Higher Education Institutions (HEIs) based on Input-Output tables for the year 2006. The HEI disaggregated table was developed from existing Input-Output tables using supplementary data from HESA and purchasing data for Scottish universities. We calculate direct, indirect and induced impacts. Most of the existing literature focuses on individual institutions by employing Keynesian Multiplier or Input-Output analysis. This paper adds to the literature by providing the first systematic study of all individual HEIs using a common framework of analysis. The results suggest that HEIs may have substantial regional economic impacts both in terms of output and employment. Furthermore analysis of the HEIs' income sources suggests they are more export intensive than is commonly acknowledged, which motivates a re-evaluation of the appropriate counterfactual in regional impact studies of HEIs.

Graduates as external stakeholders of the higher education institutions in Poland: HEIs' perception - research results
No full textThe article discusses the issue of graduates as external stakeholders of the higher education institutions (HEIs) in Poland. The main aim is to answer the question about the way HEIs perceive relations with graduates. The author discusses this problem by analyzing legal and formal regulations, the literature and the results of her own research on qualitative analysis of the content of HEIs' missions and development strategies, and also the results of survey directed to rectors of HEIs. The analysis of HEIs` missions and strategies shows that the importance of HEIs' relations with graduates is articulated in a distinctive and positive way. However, the survey results indicate that not all rectors perceive their graduates as stakeholders, thus not fully recognize its importance and the opportunities arising for HEI from this cooperation

Cooperation of higher education institutions with environment. Selected issues on measurement of HEIs' third stream activities
No full textPurpose: This article discusses cooperation of Polish higher education institutions (HEIs) with their environment and offers a way of measuring these activities. The concept and scope of the third stream are discussed and selected model and indicators of measuring HEIs’ activities in this field are presented. The Author suggests Indicator of Cooperation with Environment (ICE) in order to measure levels of HEIs’ interaction with the world around them.Methodology: The article draws on relevant literature both from Poland and abroad. In order to verify the proposed ICE indicator empirically, a survey was carried out among 100 heads of Polish HEIs. The results of the survey were analysed by using tools of descriptive statistics, and presented according to HEI types.Findings: The results show correlation between the ICE level and HEI type. The highest level of ICE is observed in public academic HEIs, which makes them stand out as a group as against the other types of HEIs. A signifi cantly lower level of ICE is identified in the case of state vocational HEIs and private HEIs, which makes them a homogeneous group in terms of ICE.Originality: As can be seen in the literature, the issue of how to measure HEIs’ third stream is rarely raised at a conceptual level and, consequently, in empirical research. The ICE indicator proposed in this article is based on simple indicators which are easy to operationalise and which reflect activities involving teaching, research, academic entrepreneurship as well as HEI management. Validation has confirmed that ICE is effective in achieving the intended measurement goals
University Rankings – Are Philippine HEIs Ready for Them?
No full textThis paper first traces the history of university rankings from the US News and World Report, the earliest, to the Times Higher Education rankings, the latest. It questions the validity of such rankings, citing weaknesses in their methodologies and the fact that data can be manipulated. Nevertheless, the author accedes that university rankings are here to stay. The paper then asks if Philippine higher education institutions are ready to be ranked. It contends that since the criteria used by rankers depend much on big financial resources, Philippine HEIs are already at a disadvantage. In addition, there remain inefficiencies in higher education that cause the deterioration of the quality of higher education, among which are the high number of HEIs, overscubscribed programs that result in an oversupply of graduates in certain disciplines, and the ten-year preparation for college.Keywords: university rankings, higher educatio
