Cognitive Attraction Theory and Moral Judgment

The present article deals with the processes that underpin moral judgment. In the specialized literature, some concepts are proven to be important mechanisms that build up the moral judgment. For instance, intuition, emotion, reasoning, moral rules, deontology and consequentialism. However, there is a lack of a comprehensive framework, which puts together those key concepts in a clear picture. The present article argues for a more comprehensive view under the light of the Cognitive Attraction Theory (CAT). The derived framework considers emotion as the main facilitator of moral judgment as it acts as the means of conceptual attraction between the different cognitive entities, including moral beliefs and rules. Based on this principle, we show how the moral judgment “evolves” from a moral intuition, sometimes endorsed by a reasoning fallacy, to an elaborated judgment that is a result of a conscious reasoning. With the help of a computer simulation performed with an artificial moral agent that incarnates a computational model of CAT, we show that moral judgment can be deontological or consequentialistic.

Who are People Willing to Date? Ethnic and Gender Patterns in Online Dating

The United States is a rapidly diversifying country with ethnic minorities comprising over a quarter of the US population. By the year 2050, over half of the United States will be ethnic minority, underscoring the importance of better understanding race relations and willingness to date intra- and inter-racially. Data from 2,123 online dating profiles were randomly collected from four racial groups (Asian, Black, Latino, and White). Results indicated that willingness to date intra-racially was generally high and that willingness to date inter-racially was lower and influenced by racial social status. Because men evidenced an overall high willingness to date inter-racially, women’s willingness to out-date provided a more accurate depiction of racial social status and exchange. Women of higher racial status groups were less willing than those from lower status groups to outdate. Results are explored and discussed in relation to different theories of interpersonal attraction and dating.

LGR5‐Positive Colon Cancer Stem Cells Interconvert with Drug‐Resistant LGR5‐Negative cells and are Capable of Tumor Reconstitution

The cancer stem cell (CSC) concept has been proposed as an attractive theory to explain cancer development, and CSCs themselves have been considered as targets for the development of diagnostics and therapeutics. However, many unanswered questions concerning the existence of slow cycling/quiescent, drug-resistant CSCs remain. Here we report the establishment of colon cancer CSC lines, interconversion of the CSCs between a proliferating and a drug-resistant state, and reconstitution of tumor hierarchy from the CSCs. Stable cell lines having CSC properties were established from human colon cancer after serial passages in NOD/Shi-scid, IL-2Rγ(null) (NOG) mice and subsequent adherent cell culture of these tumors. By generating specific antibodies against LGR5, we demonstrated that these cells expressed LGR5 and underwent self-renewal using symmetrical divisions. Upon exposure to irinotecan, the LGR5(+) cells transitioned into an LGR5(-) drug-resistant state. The LGR5(-) cells converted to an LGR5(+) state in the absence of the drug. DNA microarray analysis and immunohistochemistry demonstrated that HLA-DMA was specifically expressed in drug-resistant LGR5(-) cells, and epiregulin was expressed in both LGR5(+) and drug-resistant LGR5(-) cells. Both cells sustained tumor initiating activity in NOG mice, giving rise to a tumor tissue hierarchy. In addition, anti-epiregulin antibody was found to be efficacious in a metastatic model. Both LGR5(+) and LGR5(-) cells were detected in the tumor tissues of colon cancer patients. The results provide new biological insights into drug resistance of CSCs and new therapeutic options for cancer treatment.

The Way Ripe Tomatoes Look: An Argument Against Externalist Representationalism

Representationalist theories of the phenomenal character of conscious experience are attractive because they promise a simpler ‘naturalization’ of the mind. However, I argue that representationalists cannot endorse an otherwise attractive externalist theory of the representational contents of conscious experiences. The combination of representationalism and externalism conflicts with a true principle linking phenomenal character to perceptual indistinguishability.

Theory of polarization attraction in parametric amplifiers based on telecommunication fibers

We develop from first principles the coupled wave equations that describe polarization-sensitive parametric amplification based on four-wave mixing in standard (randomly birefringent) optical fibers. We show that in the small-signal case these equations can be solved analytically, and permit us to predict the gain experienced by the signal beam as well as its state of polarization (SOP) at the fiber output. We find that, independently of its initial value, the output SOP of a signal within the parametric gain bandwidth is solely determined by the pump SOP. We call this effect of pulling the polarization of the signal towards a reference SOP as polarization attraction, and such parametric amplifier as the FWM-polarizer. Our theory is valid beyond the zero polarization mode dispersion (PMD) limit, and it takes into account moderate deviations of the PMD from zero. In particular, our theory is capable of analytically predicting the rate of degradation of the efficiency of the parametric amplifier which is caused by the detrimental PMD effect.

Spectroscopic Investigation of the Effect of Salt on Binding of Tartrazine with Two Homologous Serum Albumins: Quantification by Use of the Debye–Hückel Limiting Law and Observation of Enthalpy–Entropy Compensation

Formation of ion pair between charged molecule and protein can lead to interesting biochemical phenomena. We report the evolution of thermodynamics of the binding of tartrazine, a negatively charged azo colorant, and serum albumins with salt. The dye binds predominantly electrostatically in low buffer strengths; however, on increasing salt concentration, affinity decreases considerably. The calculated thermodynamic parameters in high salt indicate manifestation of nonelectrostatic interactions, namely, van der Waals force and hydrogen bonding. Site-marker competitive binding studies and docking simulations indicate that the dye binds with HSA in the warfarin site and with BSA at the interface of warfarin and ibuprofen binding sites. The docked poses indicate nearby amino acid positive side chains, which are possibly responsible for electrostatic interaction. Using the Debye-Hückel interionic attraction theory for binding equilibria, it is shown that, for electrostatic binding the calculated free energy change increases linearly with square root of ionic strength. Also UV-vis, fluorescence, CD data indicate a decrease of interaction with salt concentration. This study quantitatively relates how ionic strength modulates the strength of the protein-ligand electrostatic interaction. The binding enthalpy and entropy have been found to compensate one another. The enthalpy-entropy compensation (EEC), general property of weak intermolecular interactions, has been discussed.

Application of Leiper's tourist attraction system to small-scale sport event tourism in Malaysia.

There is a lack of literature on sport tourists attending small-scale sport events and their travel behaviors in Malaysia. This lack of data makes it difficult for tourism authorities in to implement effective market segmentation and targeting. Thus it is necessary to conduct a study to explore the potential of small-scale sporting event as tourist attraction in Malaysia using Leiper’s (1990) tourist attraction system as framework. A study is conducted on participants and spectators attending a mountain bike race and motor cross events in Lake Kenyir Malaysia. Data were collected quantitatively from 400 subjects using the Leisure Motivation Scale developed by Ragheb and Beard (1983). Data were analyzed using descriptive statistics and logistic regression. Visitors to sport event at Lake Kenyir fall into three categories: (1) sport excursionist, (2) active sport tourist and (3) passive sport tourists and the majority of the respondents (81.75%) were sport tourists. The results indicate factors such as competence mastery and intellectual factors are significant variables which motivate people to seek active sport-oriented vacations. Passive sport tourists are motivated by social factors and the need to escape from over stimulating situations. This study confirmed the usefulness of Leiper’s tourist attraction theory in sport tourism.

Theory of lossless polarization attraction in telecommunication fibers: erratum

An erroneous procedure of averaging the components of the Stokes vector of a polarization scrambled beam over the Poincaré sphere introduced in our earlier paper [J. Opt. Soc. Am. B28, 100–108 (2011)] has been corrected.

Counterion condensation theory of attraction between like charges in the absence of multivalent counterions

There is abundant experimental evidence suggesting the existence of attractive interactions among identically charged polyelectrolytes in ordinary salt solutions. The presence of multivalent counterions is not required. We review the relevant literature in detail and conclude that it merits more attention than it has received. We discuss also some recent observations of a low ionic strength attraction of negatively charged DNA to the region of a negatively charged glass nanoslit where the floor of the nanoslit meets the walls, again in the absence of multivalent ions. On the theoretical side, it has become clear that purely electrostatic interactions require the presence of multivalent counterions if they are to generate like-charge attraction. Any theory of like-charge attraction in the absence of multivalent counterions must therefore contain a non-electrostatic component. We point out that counterion condensation theory, which has predicted like-charge polyelectrolyte attraction in an intermediate range of distances in ordinary 1:1 salt conditions, contains both electrostatic and non-electrostatic elements. The non-electrostatic component of the theory is the modeling constraint that the counterions fall into two explicit populations, condensed and uncondensed. As reviewed in the paper, this physically motivated constraint is supported by strong experimental evidence. We proceed to offer an explanation of the nanoslit observations by showing in an idealized model that the line of intersection of two intersecting planes is a virtual polyelectrolyte. Since we have previously developed a counterion condensation theory of attraction of two like-charged polyelectrolytes, our suggestion is that the DNA is attracted to the virtual polyelectrolytes that may be located in the nanoslit where floor meets walls. We present the detailed calculations needed to document this suggestion: an extension of previous theory to the case of polyelectrolytes with like but not identical charges; the demonstration of counterion condensation on a plane with bare charge density greater than an explicitly exhibited critical value; a calculation of the free energy of the plane; a calculation of the interaction of a line charge polyelectrolyte with a like-charged plane; and the detailed demonstration that the line of intersection of two planes is a virtual polyelectrolyte.

Heterotic E 6 GUTs and partition functions

The E 6 grand unified theory is an attractive candidate intermediate theory between the standard model and string theory. However, only one E 6 grand unified model with three generations and at least one adjoint Higgs field has been derived from string theory in the literature, and this model is phenomenologically unsatisfactory. Recently, in arXiv:1012.1690, we have constructed two new such E 6 grand unified models in heterotic asymmetric orbifolds. Although our new models themselves cannot resolve the unsatisfactory point in the previous model, our discovery raises hopes that one can construct many other such models in this framework and find better models. Here, by giving partition functions explicitly, we explain the details of our construction. Utilizing the lattice engineering technique and the diagonal embedding method, we can construct models systematically. We hope that these techniques and the details of our construction will lead to more phenomenologically desirable models.

Organization Personality Perceptions and Attraction: The role of social identity consciousness

The current study explores the theory of symbolic attraction. The theory suggests that social identity consciousness moderates the relationship between symbolic inferences between organizations and attraction to those organizations. The study explored the two dimensions of social identity consciousness (i.e., social adjustment concern and value expression concern) as moderators of the relationship between organization personality perceptions (i.e., boy scout, innovativeness, dominance, style, and thrift) and organization attraction. The results of the study suggest that value expression concern moderates the relationships between boy scout, innovativeness, style, and thrift perceptions and attraction such that the relationships between these variables are stronger among those high on value expression concern. There was no support for social adjustment concern as a moderator of these relationships.

An empirical examination of hiring decisions of experienced auditors in public accounting

PurposeThis study aims to examine the potential factors influencing the hiring decisions of experienced auditors in public accounting practices in Hong Kong.Design/methodology/approachMultinomial logistic regression is used to analyze the survey data, which is the first time such an approach has been used in the literature. A total of 337 interview rating forms are collected in actual employment interviews from two Big 4 firms. Graves and Powell's hiring model is adapted to this Hong Kong study. Interpersonal attraction theory is employed to assist in analyzing the results.FindingsThe results indicate that subjective qualifications have the highest explanatory power. Big 4 recruiters regard subjective qualifications as important considerations in the evaluation of experienced auditors. Interpersonal attraction is the second most important factor. These findings are consistent with the theory of interpersonal attraction. Perceived similarity and objective qualifications are also perceived as significant factors. Physical attractiveness, dress effect and gender are not found to be factors influencing the hiring decisions, in contrast to the findings of earlier literature in the USA.Originality/valueThese findings indicate that recruiters would look for attributes other than those primarily based on objective qualifications. Job relevant skills, knowledge and demonstrated initiatives are important. The accounting profession could conduct more training programs for auditors to improve and demonstrate their “soft skills” in the interview process so as to enhance their chances of employment, particularly during a recessionary environment.

Self-assembly of CuSO4 nanoparticles and bending multi-wall carbon nanotubes on few-layer graphene surfaces

When a colloidal suspension is allowed to wet a suitable substrate, various patterns emerge that can be varied from isolated island-like structures to fractal patterns. In this work we investigate the patterns arising from the interplay of colloidal copper sulfate suspensions containing carbon nanotubes with few-layer graphene substrates. The compositions of the thin film samples were investigated using X-ray photoelectron spectroscopy, surface topography and the nanostructure of the thin films were probed with atomic force microscope and transmission electron microscope respectively. The colloidal suspensions were characterized using contact angle and viscosity measurements. The colloidal suspensions when dip coated on few-layer graphene substrates exhibited fractal like morphology with the aggregation of copper sulfate crystallites to hexagonal platelets. This aggregation is explained invoking the depletion attraction theory. The various patterns observed experimentally were reproduced using a Monte Carlo simulation.

The role of other customer effect in corporate marketing

PurposeBy drawing on theories of social identity, attraction, social comparison and consumer identification, this research seeks to examine how consumers' perceptions of other customers of an organisation (the other customer effect) may have an influence on corporate image and consumer‐company identification. This study aims to test a model integrating these constructs in two contexts, i.e. products and services. It also seeks to investigate the attitudinal and behavioural consequences of a favourable corporate image in order to provide more insights to the argument that a corporate marketing approach helps to enhance marketing performance.Design/methodology/approachA survey of a convenience sample of 383 adult consumers is conducted. Structural Equation Modelling (SEM) is employed in order to test the proposed model. An alternative model is examined both in products and in services contexts.FindingsThe results indicate that perceptions about other customers influence customers' affective and behavioural reactions towards a company for both products and services. This finding suggests that corporate‐level marketing activities aiming to increase interaction among consumers lead to favourable corporate image and higher consumer‐company identification and hence desirable marketing outcomes. Furthermore, results show that for services the other customer effect is more prominent than for product offerings.Originality/valueThis study extends the concept of other customer effect to the context of corporate image and consumer‐company identification studies. It provides evidence that shifting towards corporate‐level marketing gives organisations another avenue for gaining a distinct position in the minds of consumers. Furthermore, by addressing both service and product contexts, it shows that other customer effect may exist beyond services studies.

MacCannell revisited in the World Heritage Kvarken Archipelago, Finland

Inspired by Dean MacCannell's Attraction theory, I will, in this paper, examine the possibilities of turning a coastal area, with no previous attempt of being a tourist destination, into a worldwide unique destination. Can a place without a history of ‘imaginaries’ become a successful image in a touristic sense? My case study is the World Heritage (WH) site Kvarken Archipelago on the West coast of Finland in the region of Ostrobothina. As the first WH in Finland based on natural uniqueness, designated in 2006, the Kvarken Archipelago is confronted with many challenges. The area is inhabited, a socio-economic locus for 2500 local inhabitants, where the WH status has been incorporated as an important asset of regional development during the last 4–5 years. My main research question is: Does the WH Kvarken Archipelago have the attributes of a tourist attraction?

Sociosexuality Predicts Women’s Preferences for Symmetry in Men’s Faces

Although men displaying cues of good physical condition possess traits that are desirable in a mate (e.g., good health), these men are also more likely to possess antisocial characteristics that are undesirable in a long-term partner (e.g., aggression and tendency to infidelity). How women resolve this trade-off between the costs and benefits associated with choosing a mate in good physical condition may lead to strategic variation in women's mate preferences. Because the costs of choosing a mate with antisocial personality characteristics are greater in long- than short-term relationships, women's sociosexuality (i.e., the extent to which they are interested in uncommitted sexual relationships) may predict individual differences in their mate preferences. Here we investigated variation in 99 heterosexual women's preferences for facial symmetry, a characteristic that is thought to be an important cue of physical condition. Symmetry preferences were assessed using pairs of symmetrized and original (i.e., relatively asymmetric) versions of 10 male and 10 female faces. Analyses showed that women's sociosexuality, and their sociosexual attitude in particular, predicted their preferences for symmetry in men's, but not women's, faces; women who reported being more interested in short-term, uncommitted relationships demonstrated stronger attraction to symmetric men. Our findings present new evidence for potentially adaptive variation in women's symmetry preferences that is consistent with trade-off theories of attraction.

Attractive quality for requirement assessment during the front‐end of innovation

PurposeThe purpose of this paper is to provide a new decision‐aided tool for selecting customer needs during the new product development process.Design/methodology/approachThe study started by examining the principles of attractive quality and its limits. The theory of attractive quality developed by Kano was used to conduct a requirement assessment and classification within four categories. The study also proposed a new method for needs analysis and, finally, an experiment with a case study was carried out for new self‐directed learning software.FindingsThis paper proposes a methodology involving the three following steps: identifying customers' needs, classifying and evaluating them, and comparing several concepts of new products. The paper proposes a matrix modeling that is based on the Kano model, which results in an analytical approach of the attractive quality theory. This enables the selection of innovative concepts and new ideas through the evaluation of their impact on needs satisfaction.Research limitations/implicationsFuture research is required in order to study the impact of the vocabulary used in the Kano questionnaire; misunderstanding these needs could lead to incorrect classification. Moreover, future work could consider other technical criteria for concept selection, including technical feasibility and cost constraints.Practical implicationsThe formality of the model (clear steps and matrix modeling) and its graphical aspect (decision made based on graphical mappings) makes it a simple decision tool. It can be used by design teams during the Front‐End phases and in activities coming upstream from the more formal and well‐structured New Product Development Process (NPDP).Originality/valueA major concern for companies during an innovation process is to discover users' needs. This paper presents an integrated method for customer environment analysis, needs identification, needs classification, and new concept selection. The most interesting concepts – those that yield satisfaction – will then continue through the innovation process.

Ovulation as a male mating prime: Subtle signs of women's fertility influence men's mating cognition and behavior.

Women's reproductive fertility peaks for a few days in the middle of their cycle around ovulation. Because conception is most likely to occur inside this brief fertile window, evolutionary theories suggest that men possess adaptations designed to maximize their reproductive success by mating with women during their peak period of fertility. In this article, we provide evidence from 3 studies that subtle cues of fertility prime mating motivation in men, thus facilitating psychological and behavioral processes associated with the pursuit of a sexual partner. In Study 1, men exposed to the scent of a woman near peak levels of fertility displayed increased accessibility to sexual concepts. Study 2 demonstrated that, among men who reported being sensitive to odors, scent cues of fertility triggered heightened perceptions of women's sexual arousal. Study 3 revealed that, in a face-to-face interaction, high levels of female fertility were associated with a greater tendency for men to make risky decisions and to behaviorally mimic a female partner. Hence, subtle cues of fertility led to a cascade of mating-related processes-from lower order cognition to overt behavior-that reflected heightened mating motivation. Implications for theories of goal pursuit, romantic attraction, and evolutionary psychology are discussed.

Love, Friendship, and Disaffection in Plato and Aristotle: Toward a Pragmatist Analysis of Interpersonal Relationships

Although much overlooked by social scientists, a considerable amount of the classical Greek literature (circa700-300BCE) revolves around human relationships and, in particular, the matters of friendship, love and disaffection. Providing some of the earliest sustained literature on people's relations with others, the poets Homer (circa 700BCE) and Hesiod (circa 700BCE) not only seem to have stimulated interest in these matters, but also have provided some more implicit, contextual reference points for people embarked on the comparative analysis of human relations. Still, some other Greek authors, most notably including Plato and Aristotle, addressed these topics in explicitly descriptive and pointedly analytical terms. Plato and Aristotle clearly were not of one mind in the ways they approached, or attempted to explain, human relations. Nevertheless, contemporary social scientists may benefit considerably from closer examinations of these sources. Thus, while acknowledging some structuralist theories of attraction (e.g., that similars or opposites attract), the material considered here focus more directly on the problematic, deliberative, enacted, and uneven features of human association. In these respects, Plato and Aristotle may be seen not only to lay the foundations for a pragmatist study of friendship, love, and disaffection, but also to provide some exceptionally valuable materials with which to examine affective relations in more generic, transhistorical terms.

Theory of lossless polarization attraction in telecommunication fibers

In this work, polarization attraction is meant to be the conservative nonlinear effect that transforms any arbitrary input state of polarization (SOP) of an intense optical signal beam fed to a nonlinear medium into approximately one and the same SOP at the output, provided that the medium is driven by a relatively stronger counterpropagating pump beam. Essentially, the combination of the nonlinear medium and the pump beam serves as a lossless polarizer for the signal beam. The degree of polarization of the outcoming signal beam can be close to 100% (90% in our present simulations). With an eye toward the development of such lossless polarizers for fiber optics applications, we theoretically study the polarization attraction effect in the optical fibers that are used in telecommunication links; i.e., randomly birefringent fibers. A generic model for the fiber-based lossless polarizers is derived, and a statistical scheme for the quantification of their performance is proposed.
