A practical approach towards social impact measurement by the example of the tip me UG
No full textSocial start-ups often lack the resources and in-depth instruction to approach social impact measurement themselves. The development of a logic model builds the starting point of any methodical impact measurement activity. Therefore, this study investigates how social ventures can develop an organizational logic model towards their intended impact goal. The findings were based on qualitative, exploratory research using semi-structured interviews to build a framework. Secondly, a case study with the social venture tip me is presented to apply the framework.
The study developed a framework that builds upon an analysis phase, to assemble required logic model content, and a logic model development phase. The first part of analysis builds upon a holistic understanding of the venture´s business model to ensure a coverage of logic model assumptions. An adapted version of the Business Model Canvas, including the discussion of the venture´s desired outcomes, delivered valuable insights in the case study. The second part is a stakeholder analysis, aiming to cover the identification of actors influencing a venture´s operational model. For this purpose, a rich picture, created by employees of tip me and instructed by the author of this study, is valued as appropriate tool to visualize complexity and gain stakeholder insights. For the logic model development phase, backwards-mapping from a venture´s impact goal allows to find a logical path from long-term outcomes to current activities. Study findings link to past research by indicating that organizations with a focused operational strategy should evaluate if output measurement is rather sensible than outcome measurement for their impact measurement activities.As start-ups sociais geralmente carecem de recursos e instruções detalhadas para abordar a medição do impacto social. O desenvolvimento de um modelo lógico constrói o ponto de partida da atividade metódica de medição de impacto. Este estudo investiga como as empresas sociais podem desenvolver um modelo de lógica organizacional em direção ao objetivo de impacto. Os resultados baseiam-se em pesquisas qualitativas e exploratórias, utilizando entrevistas semiestruturadas. Em segundo lugar, é apresentado um estudo de caso com a empresa social tip me.
O estudo desenvolveu uma estrutura que se sustenta na fase de análise, para construir o conteúdo do modelo lógico necessário e uma fase de desenvolvimento do mesmo. A primeira parte da análise consiste no entendimento holístico do modelo de negócios, para garantir uma cobertura das premissas do modelo lógico. Uma versão adaptada do Business Model Canvas, incluindo a discussão dos resultados desejados da empresa, forneceu informações valiosas no estudo de caso. A segunda parte consiste na análise dos stakeholders, identificando os agentes que influenciam o modelo operacional da empresa. Para o visualizar recorreu-se a inputs dos colaboradores da tip me.
Para a fase de desenvolvimento do modelo lógico, é mostrado que o mapeamento inverso a partir da meta de impacto de uma empresa permite encontrar um caminho lógico entre resultados de longo prazo e as atividades atuais. Os resultados do estudo apontam para pesquisas anteriores, indicando que as organizações com uma estratégia operacional focada devem avaliar se a medição do output é mais prática do que a medição do resultado final

Goldman School of Dental Medicine, 2013 (Department of Restorative Sciences and Biomaterials)Includes bibliographic references: leaves 121-129.Objectives: To evaluate the mechanical and physical properties of new self-etching (SE) and conventional resin cements with different mixing and polymerization methods, and to evaluate the effect of glow discharge (GD) plasma surface treatment on bonding cements to Zirconia.
Materials and methods: The tested cements studied were, Biscem (Bisco), Ceramir C&B (Doxa), Embrace Wetbond (Pulpdent), G-CEM (GC), Ketac-Cem (3M ESPE), Maxcem (Kerr), Monocem (Shofu), Multilink Automix (Ivoclar), Multilink Sprint (Ivoclar), Panavia F2.0 (Kuraray), RelyX Unicem (3M ESPE), RelyX Unicem 2 (3M ESPE), RelyX Ultimate (3M ESPE). RelyX ARC (3M ESPE), a conventional resin cement served as a control. For compressive strength, 20 cylinder-shaped cement speciimens (4 mm diameter x 6 mm height) were made for autocure (n=10) and photocure (n=10). For flexural strength and elastic modulus, 20 bars measuring 2 mm h x 2 mm w x 25 mm l were made for autocure (n=10) and photocure (n=10). The freshly mixed cements were placed in Teflon molds in the specified dimensions. A Triad 2000 machine (Dentsply, York Division, USA) was used for polymerization for 1 minute on each side. For the film thickness (n=5), the mixed cement (0.1 gm) was placed between 2 pre-cleaned microscopic slides and then placed between 2 flat square glass plates of uniform thickness. After each manufacturer’s recommended mixing time had elapsed, a load of 15 kg was applied vertically to the plates for 10 minutes. An electronic gauge (Digimatic Micrometer, Mitutoyo MGF. Co.) was used for measurement to the nearest micron. For the separation force test, custom-made zirconia rings measuring 12.5±0.1 mm in outer diameter, 5.5[plus or minus]0.1 mm in height and 5.9[plus or minus]0.1 mm in inner diameter (n=200) were made. Cylindrical shaped titanium rods (n=200) were machined with a uniform diameter of 5.9[plus or minus]0.01 mm and a 12 mm height. Half the specimens received glow discharge treatment for 2 minutes using a high frequency voltage, Plastic chamber and a vacuum pump. Half of these specimens were additionally thermocycled for 1500 cycles in water baths held at 5 degrees C and 55 degrees C, with a dwell time in each bath of 30 seconds and a transfer time of 15 seconds. Specimens were stored in water at 37 degrees C for 24 hours prior to testing. Specimens were tested using an Instron universal testing machine (cross-head speed of 0.5 mm/min) for their respective test. The data were analyzed by using Student's t-test, 1-way ANOVA and linear regression analyses.
Results: Compressive strength: In the auto-mix group, the mean autocure compressive strength data ranged from 185 MPa (RelyX Unicem) to 309 MPa (Multilink Automix), while the mean for the photocure group data ranged from 194 MPa (Multilink Sprint) to 306 MPa (Multilink Automix). In the hand-mix group, the mean autocure compressive strength data ranged from 198 MPa (Biscem) to 253 MPa (Panavia F2.0), while the mean for the photocure group data ranged from 198 MPa (Biscem) to 261 MPa (RelyX ARC). Flexural strength: In the auto-mix group, the mean autocure flexural strength data ranged from 42 MPa Embrace Wetbond) to 101 MPa (Multilink Automix), while the mean for the photocure group data ranged from 75 MPa (Monocem) to 117 MPa (Multilink Automix). In the hand-mix group, the mean autocure flexural strength data ranged from 69 MPa (Biscem) to 104 MPa (RelyX ARC), while the mean for the photocure group data ranged from 80 MPa (Biscem) to 121 MPa (RelyX ARC). Elastic modulus: In the auto-mix group,the mean autocure elastic modulus data ranged from 0.9 GPa Embrace Wetbond) to 5.5 GPa (RelyX Unicem), while the mean for the photocure group data ranged from 2 GPa (Monocem) to 7.7 GPa (G-CEM). In the hand-mix group,the autocure mean elastic modulus data ranged from 3.6 GPa (Biscem) to 7.2 GPa (Panavia F2.0), while the mean for the photocure group data ranged from 6.3 GPa (Biscem) to 7.7 GPa (Panavia F2.0). Film thickness: The mean film thickeness of the resin cements ranged from 14[mu]m (Monocem) to 24 [mu]m (G-CEM). Separation force: In the no-glow discharge group,the mean separation force ranged from 211 N (Ketac-Cem) to 1423 N (RelyX Ultimate), while the glow discharge group mean ranged from 304 N (Ketac-Cem) to 1821 N (RelyX Ultimate). In the no-glow discharge with themocycling group the mean separation force ranged from 249 N (Ketac-Cem) to 1782 N (RelyX Ultimate), while the mean for the glow discharge with thermocycling group ranged from 301 N (Ketac-Cem) to 1729 N (RelyX Ultimate).
Conclusions: There was a large variance in mechanical properties among the self-etching resin cements tested p[less than] 0.01). Photocuring produced significantly higher mechanical properties when compared with autocuring ([less than] 0.01). Mixing method (hand-mix vs. auto-mix) had no significant effect on mechanical properties. There was a significant diffence in film thickness among the cements tested, but all were within ADA accepted limits. GIow discharge treatment of zirconia rings made a significant difference in separation force (p [less than] 0.01) for most cements tested. Thermocycling did not show any significant difference (p[greater than] 0.01) on the retention of zirconia to titanium rods. Regression analysis indicated that both cement type, and glow discharge treatment were statistically significant factors affecting mean separation force (p[less than] 0.01)
Modeling and Reasoning about Preference-Based Context-Aware Agents over Heterogeneous Knowledge Sources
No full text© 2017, The Author(s). This paper presents a conceptual framework and multi-agent model for context-aware decision support in dynamic smart environments based on heterogeneous knowledge sources. A Protégé plug-in for rules extraction from distributed ontologies has been developed, which allows us to model context-aware agents using the notion of multi-context systems. Extracted rules can be annotated to match the users’ needs and to develop a preference model to support their preferences so as to provide a user with a more personalized services. The use of the proposed framework is illustrated using a simple fact-based preference model developed from ontologies considering two different smart environment domains
Monetary Intelligence and Behavioral Economics: The Enron Effect-Love of Money, Corporate Ethical Values, Corruption Perceptions Index (CPI), and Dishonesty Across 31 Geopolitical Entities
No full textMonetary intelligence theory asserts that individuals apply their money attitude to frame critical concerns in the context and strategically select certain options to achieve financial goals and ultimate happiness. This study explores the dark side of monetary Intelligence and behavioral economics-dishonesty (corruption). Dishonesty, a risky prospect, involves cost-benefit analysis of self-interest. We frame good or bad barrels in the environmental context as a proxy of high or low probability of getting caught for dishonesty, respectively. We theorize: The magnitude and intensity of the relationship between love of money and dishonest prospect (dishonesty) may reveal how individuals frame dishonesty in the context of two levels of subjective norm-perceived corporate ethical values at the micro-level (CEV, Level 1) and Corruption Perceptions Index at the macro-level (CPI, Level 2), collected from multiple sources. Based on 6382 managers in 31 geopolitical entities across six continents, our cross-level three-way interaction effect illustrates: As expected, managers in good barrels (high CEV/high CPI), mixed barrels (low CEV/high CPI or high CEV/low CPI), and bad barrels (low CEV/low CPI) display low, medium, and high magnitude of dishonesty, respectively. With high CEV, the intensity is the same across cultures. With low CEV, the intensity of dishonesty is the highest in high CPI entities (risk seeking of high probability)-the Enron Effect, but the lowest in low CPI entities (risk aversion of low probability). CPI has a strong impact on the magnitude of dishonesty, whereas CEV has a strong impact on the intensity of dishonesty. We demonstrate dishonesty in light of monetary values and two frames of social norm, revealing critical implications to the field of behavioral economics and business ethics.Faculty Research and Creative Activity Committee of Middle Tennessee State UniversityThe senior author would like to thank Faculty Research and Creative Activity Committee of Middle Tennessee State University and all co-authors' respective institutions for financial support, late Fr.

Monetary Intelligence and Behavioral Economics Across 32 Cultures: Good Apples Enjoy Good Quality of Life in Good Barrels
No full textMonetary Intelligence theory asserts that individuals apply their money attitude to frame critical concerns in the context and strategically select certain options to achieve financial goals and ultimate happiness. This study explores the bright side of Monetary Intelligence and behavioral economics, frames money attitude in the context of pay and life satisfaction, and controls money at the macro-level (GDP per capita) and micro-level (Z income). We theorize: Managers with low love of money motive but high stewardship behavior will have high subjective well-being: pay satisfaction and quality of life. Data collected from 6586 managers in 32 cultures across six continents support our theory. Interestingly, GDP per capita is related to life satisfaction, but not to pay satisfaction. Individual income is related to both life and pay satisfaction. Neither GDP nor income is related to Happiness (money makes people happy). Our theoretical model across three GDP groups offers new discoveries: In high GDP (rich) entities, high income not only reduces aspirations-Rich, Motivator, and Power, but also promotes stewardship behavior-Budget, Give/Donate, and Contribute and appreciation of Achievement. After controlling income, we demonstrate the bright side of Monetary Intelligence: Low love of money motive but high stewardship behavior define Monetary Intelligence. Good apples enjoy good quality of life in good barrels. This notion adds another explanation to managers' low magnitude of dishonesty in entities with high Corruption Perceptions Index (CPI) (risk aversion for gains of high probability) . In low GDP (poor) entities, high income is related to poor Budgeting skills and escalated Happiness. These managers experience equal satisfaction with pay and life. We add a new vocabulary to the conversation of monetary intelligence, income, GDP, happiness, subjective well-being, good and bad apples and barrels, corruption, and behavioral ethics.Faculty Research and Creative Activity Committee of Middle Tennessee State UniversityWe would like to thank Editor-in-Chief Alex C.

Schleiermacher’in Psikolojik Yöntemi (Hermenötiği) ve Kur’ân’a Uygulanmasının İmkânı
No full textIn terms of understanding and interpreting a text, both the Christian world and the Islamic world have developed a discipline appropriate to the nature of the belief in their own books. Schleiermacher, one of the names that had a profound effect on modern hermeneutics, proposes two methods for understanding and interpreting the New Testament (Gospels): grammatical and psychological methods. In this study, it was investigated whether the psychological method (hermeneutics) of Schleiermacher, who is a Christian theologian, can be utilized in the Qur'anic exegesis ( tafsir) and interpretation (Ta'wil), and the similarities and intersections of this method with the sciences in the Qur'anic exegesis method have been attempted to be explained. In line with this goal, first of all, information about the understanding of the holy book in Christianity and Islam was given. Afterwards, the definitions of the intuitive and comparative method, psychological and technical task proposed by Schleiermacher in his psychological method were made and its contents were explained. In the last part, it has been evaluated whether the aforementioned methods would contribute to the interpretation of the Qur'an, and if a similar method has been formed as a science in the Islamic scientific tradition or in the method of tafsir, this was also stated. In addition, it has also been investigated whether the methods that cannot be used directly in the interpretation of the Qur'an can be applied to the authors of tafsir (mufassirun) and the tafsirs they have written, in other words, to the tafsir corpus. In Schleiermacher's psychological method (hermeneutics), the main target is the text writer, not the text. The final achievement in this method, in which the author is centered, is that it is not possible to make a correct text analysis with a reading independent of the author. In this method, Schleiermacher proposes to know not only the text, but also the author and the sociocultural environment in which he lives. According to him, the geography and conditions of the author have a great influence on the formation of the text. Schleiermacher acknowledges that the authors of the Gospels; Matthew, Mark, Luke and John, were influenced by the sociocultural environment and added new meanings to the text and made additions. Therefore, he presented a method by considering how to understand a book that is partly inspired by God and partly a human product. Here, Schleiermacher built his psychological method (hermeneutics) on this understanding of revelation. According to him, the Bible texts should be read and interpreted in the context of the life and psychology of their authors. Knowing the non-linguistic context ensures a correct understanding of the Gospels. On the other hand, Muslims' faith in the holy book is completely different from Christians. The Qur'an was protected from jinn and devils in bayt al-.izza and al-lawh al-Mahfooz and no creatures were allowed to interfere during the revelation process. The Prophet (pbuh) first memorized it himself, then had it memorized by the Companions, had the revelation scribes dictate it, and it has been preserved as it was revealed until today with collected and replicated. The Qur'an is a completely divine and heavenly book, different in nature from human speech, it is the word of God in wording and meaning, and the sole owner of the Qur'an is God. The biggest difference between the Qur'an and the Bible; The Qur'an is the word of God and the Bible is a religious text containing the interpretations of the clergy. Applying Schleiermacher's psychological method in hermeneutics to the Qur'an means considering the Bible and the Qur'an, which are different from each other in terms of formation and source, as equal. Because of this difference between the two texts, using the methods and principles related to the text writer in Schleiermacher's psychological method in the interpretation of the Qur'an causes a great inconsistency. Is it possible to apply some of the methods related to the text in Schleiermacher's method in question to the text of the Qur'an? When the studies related to the Islamic scientific tradition and especially the discipline of tafsir are examined, it will be seen that a much more systematic version of Schleiermacher's methods related to the text was applied to the text of the Qur'an centuries ago. Therefore, there is no need to resort to them. On the other hand, it seems possible to apply this method to mufassir and tafsirs. Because the mufassir is a human being, and his interpretation is a human-made work. According to Schleiermacher's psychological method, it is not correct to read any tafsir as pure text. Tafsir should be evaluated together with the psycho-social situation of the mufassir. With this method, it is possible to reveal the social, political and theological thoughts that the mufassir have been influenced in their interpretations. This helps to identify right and wrong views, subjective and sociocultural effects in tafsir
Perceptions of the ethicality of favors at work in Asia: An 11-society assessment
No full textWe explore macro-level factors that shape perceptions of the ethicality of favors in Asian workplaces using the subordinate influence ethics (SIE) measure. We also expand and use the crossvergence model to examine the cross-level relationship between socio-cultural (i.e., traditional/secular; survival/self-expression; in-group favoritism) and business ideology influences (i.e., human development level, control of corruption) on perceptions of favor-seeking at work. This study examines the perceptions of a total of 4,325 managers and professionals in a diverse set of 11 Asian societies: China, Hong Kong, India, Indonesia, Malaysia, Pakistan, Singapore, South Korea, Taiwan, Thailand, and Vietnam. Our investigation focuses on both the "softer" (image management) and "harder" (self-serving) sides of subordinate influence attempts to seek favors, as well as the degree of ethical differentiation across these societies. Key results based on hierarchical linear modeling (HLM) suggest that both the World Value Survey's socio-cultural values as well as in-group favoritism contribute to our understanding of influence behaviors in Asia. Likewise, level of human development and control of corruption also appear to be promising predictors of influence ethics. In sum, our results suggest that widening the scope of the crossvergence conceptualization of socio-cultural and business ideology influences engender a better understanding of differences in attitudes toward subordinate use of favoritism across Asian societies
