Type of the research is research and development. It was limited to, identify that technopreneurship scientific learning model is practical, and then the product was tested with users; lecturers and students. The questionnaire for assessing the practicality consisted of level of practicality sheet for the users. This instrument was made by using linkert measuring scale. The practicality sheet covered lecturer and students perception towards technopreneurship scientific learning model. It can be practical if it meets the criteria of aspect which is tested to the lecturer to identify attractiveness aspect, aspects of the development process, aspect of user practicality, aspect of functionality and usability, and the aspect of reliability. The result of the research shows that technopreneurship scientific learning model is practical from the lecturer’s view. Besides, from the students’ view, by identifying the students’ interest, the process of its use, improving students` activeness in learning process, the product is also practical. These research findings prove that technopreneurship scientific learning model is practical and be able to be used in higher education, especially in practice courses which expect the students to produce a good product in the form of prototype, blueprint, and concept. This technopreneurship scientific learning model can be developed and used in different courses based on the learning needs.</p> Hendra Hidayat, Susi Herawati, Khairul ., Boy Yendra Tamin, Eril Syahmaidi ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://ijsrm.in/index.php/ijsrm/article/view/1795 Sat, 15 Sep 2018 17:10:43 +0000 When Citizens Are Minority: Toward Establishing A Comprehensive Emirati SME Support System https://ijsrm.in/index.php/ijsrm/article/view/1762 <p>This paper endeavours to contribute to developing a comprehensive framework of institutional support system in a situation where citizens and citizen-owned SMEs form a minority in their own country. This is significant because it is not confined only to the case study of this Paper, (United Arab Emirates), but is prevalent in all countries of Gulf Cooperation Council.</p> <p>Examining the current situation of Emirati-owned SME reveals many challenges and opportunities.&nbsp; After developing an empirical framework for SME support and providing analysis of the Emirati SME scene, the paper uses the benchmarking approach (and Singapore has been selected for this purpose), and refers to other relevant literature, to discuss and develop constituents of the proposed support system. It concludes that Emirati SME support system may not be sustainable if not linked to a broader strategy for the development of the country’s entire SME sector. Such a strategy, which the paper has not extended into, remains to be an area for future research.</p> Abbas Abdelkarim ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://ijsrm.in/index.php/ijsrm/article/view/1762 Wed, 05 Sep 2018 15:05:08 +0000 Some Remarks on the Estimation of Informal Economy in the Republic of Macedonia https://ijsrm.in/index.php/ijsrm/article/view/1741 <p><em>In this paper we discuss some findings on the estimation of the informal economy in a particular economical system, the Republic of Macedonia. We observed that undeviating application of standard models could produce different results and therefore some preliminary precaution has been taken. Therefore, by performing step by step analysis we conclude in acceptable values and in the evidencing of dominant factors that simulate informal economy. The work reveals the importance of model’s assumption fulfilling in the case of economic systems where observables are non-stationary and the economy itself is typically in dynamical evolution. As result of such improvement of the procedure we obtained that the country’s informal economy is going slight down starting from a local peak value touched in 2010-2011. By now it is stabilized around the values 33%-35% of GDP. We obtained herein that the majority of economic and political measures undertaken recently in the framework of informality reduction have worked in the aimed direction. From the factors point of view we obtained that contribution of some variables in the informal economy growth in the period analyzed</em></p> Dashmir Asani, Dode Prenga, Elmira Kushta ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://ijsrm.in/index.php/ijsrm/article/view/1741 Wed, 05 Sep 2018 15:17:47 +0000 The Effect of Organizational Citizenship Behavior (OCB) and Quality of Work Life (QWL) on The Employee Work Performance with Motivation As An Intervening Variables at Industrial affairs Of South Sumatera Province https://ijsrm.in/index.php/ijsrm/article/view/1764 <p>Organizational Citizenship Behavior (OCB) is a new concept in terms of performance analysis that is not regulated by the organization, and a formal reward system is not taken into account, but this behavior will encourage the effectiveness and efficiency of the overall organizational function. High employee performance will also be created when Quality of Work Life (QWL) provides comfort and prosperity in the work environment, because it is consideredbe able to increase the role and contribution of employees in an organization. High work motivation will also have an impact on the better performance given by employees to achieve the goals of the institution. The purpose of this research are to find out whether or not : OCB affects work motivation, QWL affects work motivation, OCB affects employee performance, QWL affects employee performance, Work motivation affects employee performance, The effect of work motivation as a mediation of OCB to employee performance, The effect of work motivation as a mediation of the QWL to work performance.</p> Agustina Hanafi, Bambang Bemby Soebyakto, Meldha Afriyanti ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://ijsrm.in/index.php/ijsrm/article/view/1764 Tue, 11 Sep 2018 09:45:44 +0000 Impact of Informal Groups on Organisational Performance https://ijsrm.in/index.php/ijsrm/article/view/1784 <p><em>The purpose of this study is to investigate the impact of informal groups on organizational performance. Informal groups are a very powerful social network which are constructed in response to and through actions of their members, informal groupings when viewed on the degree of their being informal, creates a managerial burden informally for managers who require additional competences to manage their activities. Informal groups exist to achieve group interest which may not necessarily be in tandem with the overall goals of the organization. The aim of this study is to identify why employees engage in informal groups. A survey research design was adopted and copies of questionnaire were administered on 319 employees of the selected construction companies, using disproportionate stratified sampling technique. The data collected were analyzed using Pearson product moment correlation. The questionnaire was validated using content validity. The reliability of the questionnaire was confirmed by determining the correlation coefficient of the data collected at two different periods. The study discovered informal groups has a significant effect on employee performance, there is a significant relationship between informal groups and their characteristics, there is a significant relationship between informal groups and self-confidence in Nigerian construction firms and Informal groups has significant influence on organizational performance in Nigeria</em></p> Dr. Cross Ogohi Daniel ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://ijsrm.in/index.php/ijsrm/article/view/1784 Sun, 16 Sep 2018 13:07:07 +0000 Cobac Control Measures On The Performance Of Mfis https://ijsrm.in/index.php/ijsrm/article/view/1791 <p>Globally, the emergence of MFIS presents an unprecedented opportunity to extend financial services to the vast majority of the population. In Cameroon, MFIs and banks are governed by a series of enactments (conventions, laws, ordinance, presidential decrees, ministerial orders and circulars). Cobac control measures are becoming increasingly important to the performance of microfinance institutions in Cameroon. This measures seems to be indispensible for customer satisfaction as a measure of performance. We therefore set out to verify the level to which these measures influence the performance of microfinancial institutions. Data was collected from 160 respondents in the northwest and littoral regions in Cameroon. Measures of dispersion were studied including inferential statistics in terms of person correlation, test of hypothesis, analysis of variance, chi square. Our results show that COBAC control measures positively influence the performance of MFIs. Thus MFIs should re-enforce the implementation of COBAC control measures instead of considering them as threats</p> Dr. Nkiendem Felix, Gahmuti Roland N., Felix Nyuysemo Ayenika, Fokeng Sylvie, Nchitu Polycarpe Asah ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://ijsrm.in/index.php/ijsrm/article/view/1791 Wed, 19 Sep 2018 16:58:23 +0000 Investment Decisions And The Parallel Funding Routes: Informal savings as a new tool of funding decision in the Cameroonian SMEs https://ijsrm.in/index.php/ijsrm/article/view/1660 <p><em>The criteria of the choice of investment elaborated by theoricians are based on rationality of deciders who after some work often consider two types of aids to investment decision: delay of getting back invested capital and net actualized value. Whereas other forms of aid to funding decision exist. We are proposing in the framework of this article, a new model of aid to funding decision corresponding to the new informal funding. We think that risk capital in the framework of informal funding (Ndjangi) can bring forth long-term funding as strategy, and solutions to questions of rationality of the heads of Small and Medium size Enterprise (SMEs) that prefers the delay of getting back invested capital, solutions to problems of decision of choice, and at last solutions to the quality of profitability of investments.</em></p> Emmanuel BEYINA ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://ijsrm.in/index.php/ijsrm/article/view/1660 Fri, 21 Sep 2018 11:06:05 +0000 Design and laying out of roads and paths in Greece for better management and development of the forest area https://ijsrm.in/index.php/ijsrm/article/view/1738 <p><em>The forest covers everyday many human needs (e.g. recreation, walking, hiking, mountaineering, training, sports, etc.). These activities are achieved through the use of paths, which are now well developed and have taken the form of a network. During the past they constituted shaped ways by pedestrians and animals in order to join places that have for man any particular interest.</em></p> <p><em>Today, with technology development, in their mapping and surveying was given to them great importance, because they serve as mentioned above many activities and at the same time constitute an ecological form of road, friendlier to the environment than other classic routes.</em></p> <p><em>In consequence, depending on the regions we want to approach, potential users, the length, the degree of difficulty and their shape, we distinguish the paths in various categories (paths of big corridors, mountaineering paths hiking trails, peripatetic paths, educational paths and in combinations of paths). Greece except from the national trails contains also parts of two international paths (E4, E6).</em></p> <p><em>The design and laying out of paths is judged essential because it constitutes important tool of sustainable management. In order to laying out of the paths and the production of maps can be used several devices and instruments such as the Global Positioning System (GPS) and the electronic compass - finder (TruePulse 360° B).</em></p> <p><em>These devices provide us with enough information about the terrain and they contribute to the creation of topographical activities in order to develop the area as it appears in this paper. The study area is a typical semi mountainous area in the Macedonia region.</em></p> <p><em>The results of the measurements are presented in GIS, where the final shape of the path is appeared, and the points of measurement are given in tables. The mapping can be extended and the results of the surveying can be included in a printed or electronic map data in order to be used by stakeholders.</em></p> Sarantis-Angelos Liampas, VASILEIOS DROSOS, professor ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://ijsrm.in/index.php/ijsrm/article/view/1738 Sat, 01 Sep 2018 17:29:26 +0000 Creative Problem Posing Activity (CPPA): A New Approach for Evaluating Creative Thinking Abilities in Mathematics https://ijsrm.in/index.php/ijsrm/article/view/1670 <p>The purpose of this study is to analyze a new measurement method in the examination of the creative thinking abilities of prospective mathematics teachers. CPPA (Creative Problem Posing Activity) is a method that is revealed with the aim of measuring the creativity of teacher candidates in mathematical problem posing. CPPA has made it possible for the teacher candidates to measure creativity components of individual mathematical creativity (fluency, flexibility, originality) separately by establishing a new scoring scheme. With participating 305 mathematics teacher candidates, this research has revealed the relationship between CPPA performances and TTCT (Torrance Creative Thinking Test) performances of teacher candidates. The findings of the research show a statistically significant relationship between teacher candidates' scores on the Torrance Test of Creative Thinking (TTCT) and their scores on the CPPA.</p> Dr. Onder Koklu ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://ijsrm.in/index.php/ijsrm/article/view/1670 Wed, 19 Sep 2018 17:06:51 +0000 Information and Communication Technology (ICT) and International Terrorism: Boko Haram and Al Shabaab in Perspective https://ijsrm.in/index.php/ijsrm/article/view/1724 <p><em>This study examined the relationship between Information and Communication Technology (ICT) and international terrorism with regards to the activities of terrorist groups. This was premised on the fact that ICT has created a network with a truly global reach for advancement of terrorist activities. The internet technology makes it easy for an individual to communicate with relative ease and anonymity, quickly and effectively across borders to an almost limitless audience. This factor made ICT and their innovative tendencies of the social media like Whatsapp, Facebook, Instagram, Youtube, Twitter etc to serve as veritable tool and motivation for terrorist groups and their activities. Historical and descriptive methods were employed in this study hence data were drawn from relevant primary and secondary sources which included published and unpublished materials. The findings of the study revealed that increased availability of ICT and other innovative tendencies has made it easier for terrorist organizations to communicate, recruit, radicalize as well as mobilize individuals to plan and coordinate terrorist attacks. Based on the above findings, it was recommended among others that understanding terrorist recruitment through the social media was vital to counter-terrorism. Hence, understanding how and why an individual is radicalize and recruited into a terrorist organization is therefore an important part of addressing the fight against terrorism. Accordingly, there should be investment in scientific research and industrial development that are more resistant for terrorist use.</em></p> Dr. Uwak, U. Eyo, Egemuka, C.

Yield and Yield Components as Affected by Mulching at Teda, Centeral Gondar, Ethiopia https://ijsrm.in/index.php/ijsrm/article/view/1672 <p>Lettuce (<em>Lactuca sativa </em>L.<em>) </em>is one of the most popular salad crops and occupies the largest production area among salad crops in the world. However, production of lettuce can be limited due to lack of improved production techniques. Farmers in northwestern Ethiopia didn’t apply mulching for lettuce. A field study was conducted at Teda in 2018 to evaluate the effect of different mulching materials on yield and yield component of lettuce (<em>Lactuca sativa </em><em>L</em>.) under irrigation. Five mulching materials used as a treatment viz: white plastic, black plastic, teff straw, chickpea straw and control (without mulch). The treatments were laid out in Randomized Complete Block Design (RCBD) with four replications. Application of mulching increased leaf width, leaf number, plant height, biological yield, root volume, dry matter and plant height. The highest and lowest yield was recorded for black plastic mulch and no mulch, respectively. The study revealed that the black plastic is the best mulching material among the organic and inorganic once for the production of lettuce in the study area.</p> Tiru Tesfa, Derajew Asres, Hulushum Woreta ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://ijsrm.in/index.php/ijsrm/article/view/1672 Wed, 05 Sep 2018 13:46:56 +0000 Linguistic reflections of children’s transformation from Circadian to Newtonian time and the direction of time https://ijsrm.in/index.php/ijsrm/article/view/1752 <p>Both linguistically and conceptually, the acquisition of time by children is pretty late when the process is compared with the acquisition and usage of linguistic elements denoting objects, states, actions and situations. This study investigated how children transform their Circadian time to Bergsonian time and how they encode Newtonian time linguistically.</p> <p>The study was carried out by the researcher’s longitudinal observation of his three daughters from the ages 2 to 10. &nbsp;In order to verify the idiosyncratic temporal production of the three children, cross-sectional data were also collected using a day organization test.</p> <p>The results show that, (a) children between the ages of 3 and 4 live more in deictic time in that they refer to momentarily completed events such as a parent’s or sibling’s coming home or doing something which is worth mentioning from point of view of the child (“Baba geldi” ‘Daddy is home.’ or “düştü” ‘(it) fell’). (b) Children live in the Circadian time until the ages of 8-11 in that they conceive of and state time with reference to zeitgebers such as sleep-wake or day-night cycles. They also live simultaneously in Bergsonian time in that they refer to temporal units (e.g. days) with reference to the closest temporal unit (e.g. Dünden sonra” ‘The day dfter yesterday’ to mean the day before yesterday and “Yarından sonra” ‘The day after tomorrow’. (d) They begin to adopt Newtonian time with reference to certain successive events such as “Two days earlier” and then refine their conceptualization of Newtonian time by referring to hours (but not minutes). &nbsp;(e) Children are pretty ahead of Newtonian time in the construction of complex temporal relations linguistically.</p> Mehmet OZCAN ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://ijsrm.in/index.php/ijsrm/article/view/1752 Sat, 01 Sep 2018 17:41:03 +0000 Research for the Investigation of Consumer Attitudes towards Online Shopping in Niğde Province https://ijsrm.in/index.php/ijsrm/article/view/1756 <p>This research study is conducted to determine consumers’ reasons for not shopping online, to explicate their attitudes towards online purchasing behaviors, and to examine whether or not their attitudes towards online purchasing behavior differ in accordance with the descriptive characteristics of the consumers. The survey questionnaires, prepared in compliance with the aim, are conducted on 502 Niğde residents chosen by convenience sampling method. The data obtained from the survey questionnaires are analyzed via SPSS 22.0 computer software. According to the results of the study; the reasons that cause online shopping include price reduction, the economics of time and finding the best product, while the reasons of avoiding online shopping include refraining from giving out identity document and credit card information, and demanding physical product trial. Participants are determined to be such individuals within a certain age range (26-35 years) who have more positive attitudes towards online shopping rather than negative attitudes, have higher education and income levels. In the research study, it is also detected that gender, the location at which the Internet is connected, and the duration of time spent on the Internet are independent of attitudes towards online shopping.</p> Hatice Elanur Kaplan ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://ijsrm.in/index.php/ijsrm/article/view/1756 Wed, 05 Sep 2018 13:57:00 +0000 An investigation into Designing Smart city in Accordance with Designing for Children toward Child-Friendly Smart Cities https://ijsrm.in/index.php/ijsrm/article/view/1686 <p>The process of urban planning should be multi-dimensional and comprehensive meaning that it takes into consideration all groups of people especially less able ones. Children are one of these groups who should be taken into consideration more in urban planning and urban design. Planning to make cities smart is one of the new approaches in urban design. However, children are often largely ignored in these plans. The researchers of the present study tried to examine the position of children in smart city-related planning. To this end, the concepts of child-friendly cities are dealt with and studied so that its common indexes with the smart city would be extracted hoping that the position of children in smart cities would be considered more.

Practioners in the discipline may find inspiration from a number of leadership approaches in the literature that include transformational, intgrative, collabroative and entrepreneurial leadership,&nbsp;<em>inter alia</em>(Meijerink,<em> S.2011). </em>Another recent and interesting addition to leaadership&nbsp; literature is found in Complexity Leadership Theory(CLT) as developed by UHl-Bien, Marion and Bill McKelvey(@007). It is premised on on seeking understanding on how organisations respond to pressures in the modern knowledge era, in the contemporary and current work environment as well as in evolving circumstances. The model draws from complexity science, which is the " study of the behaviour of large collections of ....simple, interacting units endowed with the potential to evolve with time"(Coveney, 2003, p.1058 cited in Uhl-Bien et al 2007, p.299). In this respect the central tenet behind Complexity leadership theory is the use of the concept of&nbsp; complex adaptive systems(CAS) where issues of leadership , which is understood as the capacity to influence others, are seen as not as positions of authority but roles, are entangled between members of an organisation and "can be enacted within everyinteraction between members"(Lichenstein and Plowman 2009, p.618). In unpacking the conceptual framework behind CLT, there a reflection on the dynamic relationship between the&nbsp;<em>bureacratic, administrative functions of the organisations and the emergent, informal dynamics of complex adaptive systems(CAS).</em>The current state of water management, given the competing demands of the biosphere and the socio-sphere are amenable to be relooked at using the CLT lens. The concept of adaptive water management of water resources(Pahl-Wostl, 2006,p.49) is reviewed in realtion to CLT.</p> <p>Key words: complexity theory, complex adaptive systems, creativity, learning and adaptive water management</p> <p>&nbsp;</p> <p>&nbsp;</p> Myengwa Joshua Madida Nyoni ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://ijsrm.in/index.php/ijsrm/article/view/1779 Wed, 19 Sep 2018 17:11:54 +0000 A Design and Fabrication of Fish Feed Pelleting Machine. https://ijsrm.in/index.php/ijsrm/article/view/1758 <p><strong>Abstract.</strong></p> <p>Irrespective of the increasing effort of fish farmers to grow fish continuously and feed the nation with diet full of fish,, survey has pointed fish feed as one of the outstanding factors limiting the progress of the farmers as the high cost of the feeds scares poor farmer from active farming. This paper present to you a well-designed and locally fabricated electrically powered fish feed pelleting machine, driven by three electric gear motors of 3hp, 1.8hp and 0.7hp that drive the screw conveyor at the barrel, the hopper conveyor and the extrusion cutter respectively. The components of the machine were locally sourced and locally fabricated. The hopper, the screw conveyors, the barrel and the cutter are made of stainless steel to reduce contamination due to rust. The machine measures 183mm length, 38mm width and 115mm high.

Jute is a natural fiber popularly known as the golden fiber of Bangladesh. It is one of the cheapest and strongest natural fibers and is considered the fiber for the future. Polyester is a manufactured product which tends to be very resilient, quick drying, resistant to biological damage such as mold and mildew, easy to wash and able to hold forms well. Although polyester is often maligned as a textile, it has many useful applications. The following study is an experimental research on how blending of Polyester with Jute behaves a single yarn manufactured using jute yarn manufacturing machineries. Tossa Jute of B grade and Polyester of 1.4 Denier &amp; 32 mm staple length were chosen for the blending. The blending was performed at the 2<sup>nd</sup> Draw Frame stage of jute manufacturing system and blending ratio of jute and polyester fibers is 80:20. Count of Jute blended sliver and yarn after each stage was measured and recorded. The present work is concerned with the investigation of physical properties of manufactured jute blended yarns. Tests were conducted on blended yarn to find out Count, Twist per Inch (TPI), Strength, Quality Ratio Moisture Regain, Moisture Content, Hairiness, Percentage of Fibers in the final blended yarn etc.</p> Tanvir Mahady Dip, Prof. Dr. Hosne Ara Begum, Md.

In this investigation, the inherent stability and biochemical interaction of Naproxen and its related molecules have been studied. Density functional theory (DFT) with B3LYP/ 6-31G (d, p) has been employed to optimize the structures. Frontier molecular orbital features (HOMO-LUMO gap, hardness, softness), dipole moment, electrostatic potential and thermodynamic properties (electronic energy, enthalpy, Gibb’s free energy) of these optimized drugs are investigated. Molecular docking has been performed against prostaglandin H2 (PGH2) synthase protein 5F19 to search the binding affinity and mode(s) of all compounds. It is found that, all compounds are thermodynamically stable; some of them are chemically more reactive and show better binding affinity than the parent drug. ADMET calculations predict the improved pharmacokinetic properties of all compounds. Finally, this study can be helpful for the design of new analgesic, antipyretic drug.</p> Monir Uzzaman, Mohammed Jabedul Hoque ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://ijsrm.in/index.php/ijsrm/article/view/1789 Wed, 19 Sep 2018 17:04:42 +0000
