The question of ethical decision in marketing and ethics

Resumen: Mientras que el marketing está asociado con prácticas negativas que involucran la explotación y la deshonestidad, Anton Jamnik afirma la necesidad de crear una teoría ética para éste. El artículo intenta brindar, por un lado, un breve bosquejo de las principales corrientes de la literatura de la ética del marketing y, por otro, participar de su desarrollo. El autor analiza los desafíos éticos que sur girán en el futuro, provenientes de tres fuentes distintas: las innovaciones tecnológicas, la influencia de la competencia global y la expansión de las actividades de mercado en áreas no tradicionales. Esto requerirá el desarrollo de una ética normativa realista. Para concluir, explica que la ética del marketing debería analizar hasta qué punto ha sido exitosa a la hora de resolver los desafíos éticos del mundo actual.

Relating thermodynamics to information theory : the equality of free energy and mutual information

In this thesis we uncover a new relation which links thermodynamics and information theory. We consider time as a channel and the detailed state of a physical system as a message. As the system evolves with time, ever present noise insures that the "message" is corrupted. Thermodynamic free energy measures the approach of the system toward equilibrium. Information theoretical mutual information measures the loss of memory of initial state. We regard the free energy and the mutual information as operators which map probability distributions over state space to real numbers. In the limit of long times, we show how the free energy operator and the mutual information operator asymptotically attain a very simple relationship to one another. This relationship is founded on the common appearance of entropy in the two operators and on an identity between internal energy and conditional entropy. The use of conditional entropy is what distinguishes our approach from previous efforts to relate thermodynamics and information theory.

Etika finantzetan: ikertutako gaien analisia

Ondoren aurkezten den lana bi helburu nagusi ditu. Alde batetik, Etika Finantzarioak gaur egun duen egoera aztertzea, eta bestalde analizatzea egin diren ikerketak zertan zentratu diren. Horretarako, lan hau oinarrituko da 205 ISI artikuluetan, Leire San-José (UPV/EHU) irakasleak zuzendutako Delphi baten parte direnak. Beraz lan honen zati adierazgarriena bi bloke nagusitan bananduko da. Lehenengoan, artikuluetatik atera ahal diren datu guztiz teknikoak analizatuko dira, esate baterako: publikazio urtea, zein herrialdeetan idatzi diren, zein hizkuntzetan, etab; batez ere ondorengo galderei erantzuna eman ahal izateko: noiz ikertu da gehien? Zein herrialdeetan? Zein gaiei eman zaie garrantzia handiagoa?... Bigarren atalari dagokionez, Etika Finantzarioa osatzen duten gaien gehiengoei buruz egin diren ikerketen azalpen eta komentarioak jorratuko dira. Baina aurrekoaz aparte, mapa kontzeptual bat aurkeztuko da, gai honen azpi-gai eta kontzeptu klabe bilduz; eta horrela, modu argiago batean ikusi ahal izateko Etika Finantzarioa zertan datzan, zeintzuk diren bere barnean dauden gai garrantzitsuenak, eta zein faktore nagusiak dauden gai honetan. Azkenengoz, ondorio batzuk aurkeztuko dira, horien artean gai honek etorkizunean ikertzeko duen ibilbidea egongo delarik.

Identification of differential transcript profiles between mutual crossbred embryos of zebrafish (Danio rerio) and Chinese rare minnow (Gobiocypris rarus) by cDNA-AFLP

The crosstalk between naive nucleus and maternal factors deposited in egg cytoplasm before zygotic genome activation is crucial for early development. In this study, we utilized two laboratory fishes, zebrafish (Danio rerio) and Chinese rare minnow and Chinese rare minnow (Gobiocypris rarus), to obtain mutual crossbred embroys and examine the interaction between nucleus and egg cytoplasm from different species. Although these two types of crossbred embryos originated from common nuclei, various developmental capacities were gained due to different origins of the egg cytoplasm. Using cDNA amplified fragment length polymorphism (cDNA-AFLP), We Compared transcript profiles between the mutual crossbred embryos at two developmental stages (50%- and 90%-epiholy). Three thousand cDNA fragments were generated in four cDNA pools with 64 primer combinations. All differently displayed transcript-derived fragments (TDFs) were screened by (lot blot hybridization, and the selected sequences were further analyzed by semi-quantitative RT-PCR and quantitative real-time RT-PCR. Compared with ZR embryos, 12 genes were up-regulated and 12 were down-regulated in RZ embryos. The gene fragments were sequenced and subjected to BLASTN analysis. The sequences encoded various proteins which functioned at various levels of proliferation, growth, and development. One gene (ZR6), dramatically down-regulated in RZ embryos, was chosen for loss-of-function study; the knockdown of ZR6 gave rise to the phenotype resembling that of RZ embryos. (c) 2008 Elsevier Inc.

Mutual passivation of donors and isovalent nitrogen in GaAs

We study the mutual passivation of shallow donor and isovalent N in GaAs. We find that all the donor impurities, Si-Ga, Ge-Ga, S-As, and Se-As, bind to N in GaAsN, which has a large N-induced band-gap reduction relative to GaAs. For a group-IV impurity such as Si, the formation of the nearest-neighbor Si-Ga-N-As defect complex creates a deep donor level below the conduction band minimum (CBM). The coupling between this defect level with the CBM pushes the CBM upwards, thus restoring the GaAs band gap; the lowering of the defect level relative to the isolated Si-Ga shallow donor level is responsible for the increased electrical resistivity. Therefore, Si and N mutually passivate each other's electrical and optical activities in GaAs. For a group-VI shallow donor such as S, the binding between S-As and N-As does not form a direct bond; therefore, no mutual passivation exists in the GaAs(S+N) system.

Superconducting charge qubits: The roles of self and mutual inductances

We study the essential roles of self and mutual inductances in superconducting charge qubits and propose a scheme to couple charge qubits by means of mutual inductance. We also show that the Hamiltonians can be exactly formulated in compact forms in the spin-1/2 representation for both single- and double-qubit structures.

The phenomenon of mutual media in polypyrrole with electroactive ions

The dependence of the differential capacitance of polypyrrole doped with several typical dopants on potential is presented, which shows that the differential capacitance varies with the potential, the doped polypyrroles with electroactive ions give the largest capacitance near their formal potentials, which is attributed to the mutual media for electron transfer between polypyrrole and electroactive dopants. The existence of two conducting phases was observed in the complex capacitance plots. The electroactive anions act as an intra-conducting-phase medium for electron transfer, the electroactive cations act as an inter-conducting-phase medium for electron transfer. The mutual media between polypyrrole and redox dopants lead to the increase of the discharging time.
