DTMOS-Based 0.4V Ultra Low-Voltage Low-Power VDTA Design and Its Application to EEG Data Processing

In this paper, an ultra low-voltage, ultra low-power voltage differencing transconductance amplifier (VDTA) is proposed. DTMOS (Dynamic Threshold Voltage MOS) transistors are employed in the design to effectively use the ultra low supply voltage. The proposed VDTA is composed of two operational transconductance amplifiers operating in the subthreshold region. Using TSMC 0.18µm process technology parameters with symmetric ±0.2V sup¬ply voltage, the total power consumption of the VDTA block is found as just 5.96 nW when the transconductances have 3.3 kHz, 3 dB bandwidth. The proposed VDTA circuit is then used in a fourth-order double-tuned band-pass filter for processing real EEG data measurements. The filter achieves close to 64 dB dynamic range at 2% THD with a total power consumption of 12.7 nW

Religion as source of moral energy for Turkish enterpreneurs

This article was presented at the 33rd Annual ISBE Conference in Lindon, 2010Turkey has a distinctive status within the Muslim world. It is a Muslim country with a greater than 95% Muslim population, and yet it is the only Muslim country that has inscribed the principle of secularism (laiklik) into its constitution. From the very beginning of the Republic, Turkish society has experienced polarization between the ‘Islamists’ and the ‘secularists’. As in every major religion, the Islamic faith prescribes ethical/moral values which shape the way of life at both the level of the individual and society. Unsurprisingly, it is possible to see Islamic moral principles also filtering through to regulate business life

Weeds of onion fields and effects of some herbicides on weeds in Cukurova region, Turkey

Weeds are one of the most important problems in onion (Allium cepa L.) production areas, since onion plants are poor competitors. This study was conducted in order to identify the weed species in onion fields in  Cukurova Region, establish the effects of some herbicides on weeds and the yield of onion in reducing the  existing phytotoxicity problem on onion plants between 2006 and 2007. A total of 105 weed species belonging  to 30 families were identified in fifty onion fields that were surveyed. Top five species were found as Medicago  polymorpha L., Convolvulus arvensis L., Avena sterilis L., Chenopodium album L. and Sinapis arvensis L. with 84, 74, 68, 66 and 66 frequencies (%), respectively. To determine the effects of herbicides on weeds and onion yield, the experiments were done in two different onion fields. Among the treatments, oxadiazon and   oxyfluorfen provided a better control than pendimethalin and tepraloxydim on weed coverage and density, but oxyfluorfen caused phytotoxicicity on onion even at reduced doses. Weed-free plots gave the highest yield  (16.2a kg/m2) and were followed by oxadiazon (11.9b kg/m2), oxyfluorfen (11.7b kg/m2), pendimethalin  (10.0c kg/m2), tepraloxydim (9.6c kg/m2) and weedy check (9.1c kg/m2). Results, in which weed-free check caused 76.3% increase in the onion yields when compared with weedy checks, show that weed control is very important for onion production.Key words: Weed, onion, oxadiazon, oxyfluorfen

An Analogy Explanation for the Evaluation of Entrepreneurial Opportunities

Entrepreneurs evaluate opportunities under conditions of uncertainty; they make judgments. In order to understand these evaluations, I develop an analogical model that represents an entrepreneurial opportunity in the mind of an individual. The model proposes that an opportunity is an analogical knowledge transfer from a source business domain to a target business domain. According to the model, the cognitive distance between the domains influences the opportunity evaluation. Additionally, the inspiration behind the analogy construction influences the opportunity evaluation. The empirical design employs a hypothetical scenario experiment and the results show that the two analogical properties matter for evaluation

The balanced scorecard application as a multi-dimensional performance evaluation model

Günümüzde küreselleşmenin sonucunda sosyal, ekonomik ve teknolojik gelişmeler ile birlikte rekabet ortamı hızla ve sürekli olarak değişmektedir. Bu hızlı değişim, kurumları güncel stratejilere sahip olmak ve bunları uygulamaya koymak zorunda bırakmaktadır. Birçok ülkede olduğu gibi Türkiye’de de bu değişimin farkında olan birçok kurum farklı ve kullanılabilir strateji arayışına girmişlerdir. Ülkemizde henüz yeni uygulanmaya başlayan stratejilerden birisi de dengeli başarı göstergesi’dir. Dengeli başarı göstergesi ile işletmeler fiziksel varlıkların yanında maddi varlığı olmayan değerlerinde ölçümünü yapabilmektedirler. Bu ölçümler finansal boyut, müşteri boyutu, içsel süreç boyutu, öğrenme ve gelişme boyutu olarak tanımlanan 4 boyut ile yapılmaktadır.As a result of the widespread globalization and social, technological and economic advances, competition settings have undergone swift and steady changes. This swift change compels establishments to have updated strategies and to put these strategies into effect. As in many countries, in Turkey as well, establishments aware of these changes have attempted to seek different and feasible strategies. One of the strategies that has recently begun to be implemented is balanced scorecard method. With the method of balanced scorecard method, establishments are able to perform measurements of material assets as well as non-material assets. These measurements are performed in 4 dimensions defined as financial perspective, customer perspective, internal process perspective, learning and growth perspective

Tamburlaine the Great: “The Scourge and Wrath of God”

AbstractThe relationship between religion and war appears to be a very complex one. Whether loved or abhorred they have always co-existed despite the fact that religion has continuously condemned acts of pillaging, destroying, or devastating. In essence, religion functions as a powerful force in fashioning the contours of all essential perceptions of war and peace; whereas, war mirrors and shapes human identity and purpose in a dreadful context of struggle where killing of ‘others’ is rendered not only urgent and legal, but also honorable. For the ancients, war was the means by which gods retained their divine order. It was declared against the enemy who had sinned against the gods, thereby making this ‘just war.’ Aristotle was among the first to comment on the theory of “just war,” for whom war was not an end in itself but a means to justifiable ends. His famous expression “war must be for the sake of peace” (Politics 1333b37) was influential on all those early modern English playwrights who were willing to translate the wars of religion fought between the Muslim Turks and the Christian Europeans to the English stage. Tamburlaine the Great Part I and II were the first plays Christopher Marlowe wrote for the Elizabethan audience with the purpose of playing up the popular sentiment of hatred against the Ottoman Turks, whose military victories in Europe had earned them the title of ‘the present Terror of the World.’ In this paper, I intend to argue that Marlowe's rhetorical style transforms his military hero, Tamburlaine, from a merciless tyrant, indulging in the unjust profiteering of plundering, ravaging and killing to satisfy his insatiable lust for dominion, into “the Scourge and Wrath of God,” a divine agent adorned with God-ordained madness, to mete out punishment to those who have sinned against the God

Determinants of Causal Ambiguity and Difficulty of Knowledge Transfer within the Firm

The knowledge-based view of the firm portrays knowledge assets as the basis of sustainable competitive advantage. However, leveraging the knowledge available to the firm is not straightforward. The transfer of best practices within the firm or the replication of a certain routine poses challenges for managers. Causal ambiguity of knowledge makes it difficult to transfer practices into other contexts within the firm. In this paper, a new framework is proposed that identifies four antecedents to causal ambiguity: complexity, tacitness, relevance to the existing knowledge base, and the locality of knowledge. The paper concludes with the implications of the framework
