Comparison of Psychiatric Symptoms in Carcinoma of the Pancreas with Those in Some Other Intra-abdominal Neoplasms

Abstract: Study of 46 consecutive patients who had carcinoma of the pancreas revealed that 76 percent had psychiatric symptoms which appeared to be closely related to the presence of the neoplasm. Symptoms of depression, anxiety, and premonition of serious illness were characteristic. Since the psychiatric symptoms appeared before any other symptoms in nearly half of the patients, these symptoms should be regarded as an aid in the diagnosis of carcinoma of the pancreas.

A Theory of Development From the Late Teens Through the Twenties

Abstract: Emerging adulthood is proposed as a new conception of development for the period from the late teens through the twenties, with a focus on ages 18-25. A theoretical background is presented, Then evidence is provided to support the idea that emerging adulthood is a distinct period demographically, subjectively, and in terms of identity explorations. How emerging adulthood differs from adolescence and young adulthood is explained. Finally, a cultural context for the idea of emerging adulthood is outlined, and it is specified that emerging adulthood exists only in cultures that allow young people a prolonged period of independent role. exploration during the late teens and twenties.

Conservation of resources. A new attempt at conceptualizing stress.

Abstract: Major perspectives concerning stress are presented with the goal of clarifying the nature of what has proved to be a heuristic but vague construct. Current conceptualizations of stress are challenged as being too phenomenological and ambiguous, and consequently, not given to direct empirical testing. Indeed, it is argued that researchers have tended to avoid the problem of defining stress, choosing to study stress without reference to a clear framework. A new stress model called the model of conservation of resources is presented as an alternative. This resource-oriented model is based on the supposition that people strive to retain, project, and build resources and that what is threatening to them is the potential or actual loss of these valued resources. Implications of the model of conservation of resources for new research directions are discussed.

Romantic Love Conceptualized as an Attachment Process

Abstract: This article explores the possibility that romantic love is an attachment process--a biosocial process by which affectional bonds are formed between adult lovers, just as affectional bonds are formed earlier in life between human infants and their parents. Key components of attachment theory, developed by Bowlby, Ainsworth, and others to explain the development of affectional bonds in infancy, were translated into terms appropriate to adult romantic love. The translation centered on the three major styles of attachment in infancy--secure, avoidant, and anxious/ambivalent--and on the notion that continuity of relationship style is due in part to mental models (Bowlby's "inner working models") of self and social life. These models, and hence a person's attachment style, are seen as determined in part by childhood relationships with parents. Two questionnaire studies indicated that relative prevalence of the three attachment styles is roughly the same in adulthood as in infancy, the three kinds of adults differ predictably in the way they experience romantic love, and attachment style is related in theoretically meaningful ways to mental models of self and social relationships and to relationship experiences with parents. Implications for theories of romantic love are discussed, as are measurement problems and other issues related to future tests of the attachment perspective.

Self-discrepancy: a theory relating self and affect.

Abstract: This article presents a theory of how different types of discrepancies between self-state representations are related to different kinds of emotional vulnerabilities. One domain of the self (actual; ideal; ought) and one standpoint on the self (own; significant other) constitute each type of self-state representation. It is proposed that different types of self-discrepancies represent different types of negative psychological situations that are associated with different kinds of discomfort. Discrepancies between the actual/own self-state (i.e., the self-concept) and ideal self-states (i.e., representations of an individual's beliefs about his or her own or a sitmifieant other's hopes, wishes, or aspirations for the individual) signify the absence of positive outcomes, which is associated with dejection-related emotions (e.g., disappointment, dissatisfaction, sadness). In contrast, discrepancies between the actual/own self-state and ought self-states (i.e., representations of an individual's beliefs about his or her own or a significant other's beliefs about the individual's duties, responsibilities, or obligations) signify the presence of negative outcomes, which is associated with agitation-related emotions (e.g., fear, threat, restlessness). Differences in both the relative magnitude and the accessibility of individuals' available types of self-discrepancies are predicted to be related to differences in the kinds of discomfort people are likely to experience. Correlational and experimental evidence supports the predictions of the model. Differences between self-discrepancy theory and (a) other theories of incompatible self-beliefs and (b) actual self negativity (e.g., low self-esteem) are discussed.

Developing and Validating Trust Measures for e-Commerce: An Integrative Typology

Abstract: Evidence suggests that consumers often hesitate to transact with Web-based vendors because of uncertainty about vendor behavior or the perceived risk of having personal information stolen by hackers. Trust plays a central role in helping consumers overcome perceptions of risk and insecurity. Trust makes consumers comfortable sharing personal information, making purchases, and acting on Web vendor advice--behaviors essential to widespread adoption of e-commerce. Therefore, trust is critical to both researchers and practitioners. Prior research on e-commerce trust has used diverse, incomplete, and inconsistent definitions of trust, making it difficult to compare results across studies. This paper contributes by proposing and validating measures for a multidisciplinary, multidimensional model of trust in e-commerce. The model includes four high-level constructs--disposition to trust, institution-based trust, trusting beliefs, and trusting intentions--which are further delineated into 16 measurable, literature-grounded subconstructs. The psychometric properties of the measures are demonstrated through use of a hypothetical, legal advice Web site. The results show that trust is indeed a multidimensional concept. Proposed relationships among the trust constructs are tested (for internal nomological validity), as are relationships between the trust constructs and three other e-commerce constructs (for external nomological validity)--Web experience, personal innovativeness, and Web site quality. Suggestions for future research as well as implications for practice are discussed.
