Exact ferromagnetic ground state of pentagon chains

We model conducting pentagon chains with a multi-orbital Hubbard model and prove that well below half filling, exact ferromagnetic ground states appear. The rigorous method we use is based on the transformation of original hamiltonian into positive semidefinite form. This technique is independent of the spatial dimension and does not require integrability of the model. The obtained ferromagnetism is connected to dispersionless bands but in a much broader sense than flat-band ferromagnetism requires, where on every site a Hubbard term is present. In our case, only a small percentage of, even randomly distributed, sites are only interacting.     

“Chaotic soup of politics:” a Native American Indian mental health perspective

Through a grounded theory process, tribal politics emerged as a core theme from interviews with mental health providers (MHPs) and Native American Indian people experiencing persistent mental illness (PMI). Interviews were conducted over a four-year period with 13 Indian MHPs and administrators, and 18 persons experiencing PMI. Symbolic Interactionism was the informing framework. Findings indicate that reservation life promotes a high immersion in Eurocentric politics, which negatively affects the person with PMI in their maintenance of a healthy spirit balance. To be effective, MHPs need immersion in; the oneness of culture, spirituality, and politics of the community; knowledge of the tribal history; and communication with elders/spiritual leaders. This personal growth could facilitate provision of culturally responsive care needed for a client's navigation of intergovernmental regulations. MHPs should work for adequate funding policies of human service centers while supporting the establishment of indigenous governing practices through tribal sovereignty.     

Understanding coexistence of internal states in children and adults

We investigated the conceptualization of suffering and well-being states pertaining to physical and psychological domains by examining children's and adults’ acceptance of coexistence of two co-occurring internal states. Children and adults decided whether pairs of states may coexist, justified their answers, and reported whether they had personal experience of that. The pairs of states could involve same valence and different domain, different valence and different domain, and different valence and same domain. The results showed that acceptance, plausibility, complexity, and causality of justifications vary depending on age and/or type of state co-occurrence. The role of factors like cognitive processing, personal experience, and asymmetric organization of the constructs of valence and domain is discussed, in light of the applied relevance of the findings.     

Flat intentions – crazy dispositions?

Future-directed intentions, it is widely held, involve behavioral dispositions. But of what kind? Suppose you now intend to Φ at future time t. Are you thereby now disposed to Φ at t no matter what? If so, your intention disposes you to Φ even if around t you will come to believe that Φ-ing would be crazy. And would not that be a crazy intention to have? – Like considerations have led Luca Ferrero and others to believe that only intentions with strong internal conditions are capable of rationality. This paper explores in how far a broadly dispositional view of intention supports their claims. Its first point will come as a surprise: Intentions indeed involve dispositions toward follies in plenty. Natural objections against this bizarre-sounding claim are shown to fail, and standard counterfactual analyses of disposition locutions are shown to underpin it further. However, since the dispositions at issue are pro tanto dispositions, the consequences are not as odd as might be expected: When hedged by reasonable habits to reconsider one’s intentions, dispositions toward follies do not entail any actual crazy behavior. On balance, unconditional intention is therefore found rational after all. Dispositions toward crazy actions need not be crazy dispositions.     

The Traumatic Grief Inventory Self-Report Version (TGI-SR): Introduction and Preliminary Psychometric Evaluation

Persistent Complex Bereavement Disorder (PCBD) is a disorder of grief newly included in the “Emerging Measures and Models” section of the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013 American Psychiatric Association. (2013). Diagnostic and statistical manual of mental disorders (5th ed.). Washington, DC: Author. [Google Scholar]). Prolonged Grief Disorder (PGD) is a disorder with similar symptoms, likely to be included in the forthcoming 11th edition of the International Classification of Diseases (ICD-11; World Health Organization, 1992 World Health Organization. (1992). International classification of diseases and related health problems (10th revision). Geneva, Switzerland: World Health Organization. [Google Scholar]). We developed the Traumatic Grief Inventory Self-Report version (TGI-SR), an 18-item measure, for the assessment of symptoms of PCBD and PGD in clinical and research settings. This study was an initial attempt to evaluate psychometric properties of the TGI-SR. To this end, the measure was administered to 327 patients of a mental health institute specialized in the treatment of psychopathology associated with loss and trauma. We found evidence that items of the TGI-SR (all 18 items, as well as the selection of 17 items representing PCBD criteria, and 11 items representing PGD criteria) loaded on one dimension. The TGI-SR demonstrated strong internal consistency. Elevated scores on the TGI-SR were significantly correlated with elevated scores on indices of psychopathology and lower quality of life, attesting to the concurrent validity. Receiver operation characteristic (ROC) analyses of the TGI-SR total score against provisional diagnoses of PCBD and PGD yielded a high area under the curve index suggesting that the TGI-SR total score can be used as an indicator for probable diagnoses of both PCBD and PGD. Results of this study provide initial evidence that PCBD and PGD symptoms may be readily and reliably measured using the TGI-SR.     

Subjective distress associated with chronic stuttering

Stuttering is a chronic condition involving involuntary disruption to speech fluency. While elevated social anxiety has been found to be a risk factor for adults who have stuttered all their lives, it is unclear how stuttering influences other negative mood states such as interpersonal sensitivity and depressive mood. Consequently, controlled research was conducted that investigated negative affectivity across a number of domains in adults who stutter. Participants included 200 adults who have stuttered since childhood, with comparisons made to 200 non-stuttering controls of similar age and sex. The adults who stuttered were found to have significantly elevated levels of distress and negative mood states compared to the controls. As expected, significant differences were found for anxiety, however, significant and substantial differences were also found across a broad range of negative affect, including dimensions such as somatization, interpersonal sensitivity, depressive mood, hostility and paranoia. The implications of these findings for the better management of stuttering are discussed.Educational objectives: The reader will be able to describe: (a) the negative impact of a chronic disorder like stuttering on people who have stuttered all their life; (b) the factor structure of the SCL-90-R; (c) the negative affectivity construct, and (d) the difference between psychogenic theories of stuttering and neurological theories of stuttering.     

Within- and between individual variability of personality characteristics and physical exercise

Using two independent samples, the study investigated links of within- and between-individual variability in personality states in three personality domains—Neuroticism, Extraversion, and Conscientiousness—with physical activity. Activity was defined as self-reported quantity of exercising or walking/cycling. More physical activity was associated with people reporting higher levels of Extraversion and Conscientiousness than they usually did, with the associations clearly replicating across samples and generalizing to all items of these domains. This pattern tended to reflect associations at the level of between-individual differences. When the three domains simultaneously predicted activity, within-individual variance in Neuroticism also emerged as a positive predictor, whereas between-individual level associations waned. The findings are consistent with within-individual differences in personality ratings reflecting meaningful, context-relevant variability.     

Staying on track: Planned goal striving is protected from disruptive internal states

Past implementation intention research focused on shielding goal striving from disruptive internal states (e.g., being anxious) by forming if-then plans that link these very states to instrumental coping responses. In the present line of research, we investigated whether planning out goal striving by means of if-then plans specifying opportunities to initiate goal-directed responses also protects goal striving from the negative impact of disruptive internal states. Indeed, in the face of disruptive internal states, participants who had been asked to form implementation intentions that targeted opportunities for initiating goal-directed responses outperformed participants with a mere goal intention to do well on a focal task goal. Actually, implementation intention participants performed as well as control participants who were not burdened by disruptive internal states such as being in a certain mood (Study 1), ego-depleted (Study 2), or self-definitionally incomplete (Study 3). Results are discussed by pointing to the importance of hypo-egoic self-regulation.     

Antecedents and consequences of career decisional states in adolescence

This longitudinal study tested students in Grade 8 and again in Grade 10 on career (maturity, barriers, indecision, decision-making and self-efficacy), well-being (self-esteem, life satisfaction, and coping), and social (school achievement, paid work experience) variables. Students were allocated to decided or undecided conditions at T1, T2 and across T1-T2, based on self-reported global decidedness ratings. As predicted, the undecided students had poorer career, well-being, and social outcomes than the decided students at T1 and T2. The undecided group was also less likely to report having paid work experience at T1, and to be overrepresented by females at T2. Students who were undecided at T1 and T2 (i.e., continuously undecided) fared poorer than students who were decided at T1 and T2 (continuously decided) and students who changed decision status from T1 to T2 (i.e., developmentally undecided). Females were more likely to be continuously undecided, although continuously undecided males were more complacent and more likely to use maladaptive strategies than females. Implications of being temperamentally versus developmentally undecided are discussed.
