Second language processing: an analysis of theory, problems and possible solutions

Second Language Processing examines the problems facing learners in the second language classroom from the theoretical perspectives of Processing Instruction (structured input) and Enhanced Input. These two theories are brought to bear on a variety of processing problems, such as the difficulty of connecting second language grammatical forms encoding tense and mood as well as noun-adjective agreement with their meaning. Empirical studies examine a range of languages including Japanese, Italian and Spanish, through which the authors suggest practical solutions to these processing problems.

Adult personality inconsistency and problems with parents: uncovering the roots of the false self

Research has established that individuals who tend to vary their personality depending on who they are with, show a variety of signs of psychological maladjustment in comparison to those who do not; they show more negative affect (Baird, Le and Lucas, 2006), lower life satisfaction (Suh, 2002), lower self-esteem (Sheldon et al., 1997), lower role-satisfaction (Donahue et al., 1993), higher rates of depression (Lutz and Ross, 2003), more anxiety (Diehl, Hastings and Stanton, 2001) and poorer physical health (Cross, Gore and Morris, 2003). It has also been shown that personality variability is positively related to the experience of inauthenticity and falsity (Sheldon et al., 1997). Donahue, Roberts, Robins and John (1993) found that personality inconsistency of this type is related to tension within the family. Psychoanalytic theory has also linked the operation of an adult false self to experiences with parents, particularly in early life (Winnicott, 1960). It was hypothesized that personality variability and the adult experience of falsity in social situations would be related to an emotionally unstable relationship with parents. The method to test this comprised a questionnaire-based survey given to a non-clinical population. The final sample comprised 305, with 193 women and 112 men, aged from 19 to 55. The first questionnaire asked participants to rate personality traits, including emotional stability, in three social contexts - with parents, with friends and with work colleagues. The second part involved 3 questions; participants were asked to select in which of the aforementioned three social contexts they felt “most themselves”; in which they were “most authentic” and in which they “put on a front”. It was found, consistent with predictions, that an index of overall personality variability calculated from the personality questionnaire correlated strongly with emotional instability around parents (r = 0.46, p<0.001), while not correlating with emotional instability in either of the other two contexts measured. This suggests a specific link between a person’s relationship with their parents and their overall personality integration. Furthermore, it was found that participants who cited one of the three social contexts (parents, friends, work colleagues) as being one in which they were “more themselves” or “more authentic” had significantly higher ratings of emotional instability with parents than those participants who found that they were equally authentic across settings (F = 9.8, p<0.005). The results suggest a clear link between a person’s relationships with their parents and their adult personality integration. An explanation is that individuals who experience an anxious or ambiguous attachment with their parents in childhood may fear rejection or abandonment in later life, and so habitually adapt their personality to fit in to social contexts as adults, in order to be accepted by others and to minimize the possibility of social rejection. These individuals meanwhile retain an emotionally unstable relationship with their parents in adulthood. This interpretation is speculative but is open to empirical testing. Clinicians should be aware that attachment problems with parents may underlie poor personality integration in adulthood.

Application of regularization methods to damage detection in large scale plane frame structures using incomplete noisy modal data

This paper presents an approach for detecting local damage in large scale frame structures by utilizing regularization methods for ill-posed problems. A direct relationship between the change in stiffness caused by local damage and the measured modal data for the damaged structure is developed, based on the perturbation method for structural dynamic systems. Thus, the measured incomplete modal data can be directly adopted in damage identification without requiring model reduction techniques, and common regularization methods could be effectively employed to solve the developed equations. Damage indicators are appropriately chosen to reflect both the location and severity of local damage in individual components of frame structures such as in brace members and at beam-column joints. The Truncated Singular Value Decomposition solution incorporating the Generalized Cross Validation method is introduced to evaluate the damage indicators for the cases when realistic errors exist in modal data measurements. Results for a 16-story building model structure show that structural damage can be correctly identified at detailed level using only limited information on the measured noisy modal data for the damaged structure.

Problems of dynamic in mediterranean forests

The mediterranean forest ecosystems constitute a complex unit which is marked off the Northern and middle European ones by its climate, ecology and management.The ecosystems are related to a climate with estival droughtlasting from 1 to 6 months and the peculiar species which constitute them are generally not worth much.The anthropic pressure exerts especially by grazing and moreover they have been stricken by dramatic fires for many decades. Their large variety related to the bioclimatic and edaphic heterogeneity of the region can explain why the data concerning their functioning and dynamics are still fragmentary. Besides, their ecological and pedological characteristics make uneasy the use of schemes and patterns designed for middle european forests.
