The notion of leadership competencies is a much-debated issue. In this article, we propose that how the leader makes sense of his or her competencies is key to leadership practice. Specifically, we look at how leaders reconcile discrepancies between the self-perceived proficiency of various competencies and their corresponding importance. Empirically, we study leaders within the music domain – how choral conductors make sense of their competencies in the shaping of their professional practice. We investigated how choral leaders in Scandinavia ( N = 638) made sense of their competencies in the face of demands in their working situations. A mixed methodology was used, comprising a quantitative survey with qualitative comments and in-depth interviews with a selection of the respondents. The results show that when choral leaders shape their practice, they frequently face competency gaps that compel them to act or adjust their identity. The key to this sensemaking process is how they move competency elements they master to the foreground and wanting elements to the background. The concept of ‘sensemaking affordance’ is introduced to account for how various leader competency categories are negotiated to safeguard overall efficacy.

An essential component of youths’ successful development is learning to appropriately respond to emotions, including the ability to recognize, identify and describe one’s feelings. Emotional competence refers to one’s ability to express or release one’s inner feelings or emotions. Self-esteem reflects a person’s overall subjective emotional evaluation of his or her own worth. It is a judgment of oneself as well as an attitude toward the self. General well being refers to the harmonious functioning of the physical as well as psychological aspects of the personality, giving satisfaction to the self and benefit to the society. The present study focuses on the self esteem and general well being in adolescents with low vs high emotional competence. For this purpose, first of all emotional competence scale was administered on 260 adolescents within the age range of 15-18 years, to identify the low emotionally competent and high emotionally competent adolescents. After the sample selection of 152 subjects (76 low emotionally competent and 76 high emotionally competent) Rosenberg’s Self-esteem scale and General well being scale were administered. Results indicate that high emotionally competent adolescents have high self-esteem and better general well being than low emotionally competent adolescents.

The aim of this paper is to analyse the relationship between autobiography, pho-tography and autofiction in a selection of 20th century French autobiographies, such as Roland Barthes par Roland Barthes by Roland Barthes, L’Amant by Marguerite Duras, L´Image fantôme by Hervé Guibert. I will examine the complex relationship these auto-biographers maintain with the photographic portraits they choose to integrate or simply allude to in their autobiographies and show how the conflict between textual and visual images of the self reinforce the fine line between autobiography and autofiction.

La presente investigación tiene como objetivo describir, analizar y comparar la autoestima y las habilidades sociales de un grupo de jóvenes, entre 17 y 24 años de edad, consumidores de drogas que se encuentran realizando tratamiento en la comunidad terapéutica Aylén (Argentina). Es una investigación de tipo descriptiva comparativa, con un diseño de diferencias entre grupos (G1, grupo de admisión) y (G2, grupo de reinserción social). La muestra estuvo conformada por 54 sujetos (25 para grupo de admisión y 29 para el grupo de reinserción social). Los instrumentos utilizados fueron el inventario de Autoestima de Barksdale y la Escala de Habilidades sociales de Goldstein, las cuales fueron adaptadas y validadas para ser aplicadas a la población de estudio. Asimismo, a partir de los procedimientos de validación de estos instrumentos se propusieron para cada uno, nuevos agrupamientos de factores. Los resultados mostraron, bajos niveles de autoestima para ambos grupos y entre niveles bajos y normales de habilidades sociales en cada una de las categorías componentes y el total. Finalmente, no se confirmaron las hipótesis de diferencias significativas en los niveles de autoestima y los niveles de habilidades sociales entre los jóvenes en etapa de admisión y los jóvenes en etapa de reinserción social. AbstractThe objective of the present investigation is to analyze and compare the socials skills and the self-esteem of a group of juveniles between the ages of 17 and 24 years, drug addicts, both under medical treatment in a Community center in Argentina. This is a comparative-descriptive study, with the design of two groups: G1 for admission group and G2 for the reinsertion group. The sample was made of a group of 56 people, 25 for the admission group and 29 for the social reinsertion group. The instruments used were the Goldstein Social Skills Scale and the Self-Esteem Inventory from Barksdale, that were adapted for the use in such case. Also for the use of such instruments, new validation measures were implemented in the selection of the variables. The results showed low levels of self esteem for both groups and between low and normal levels of social skills in each category. Finally, no important differences were founded in the levels of self esteem between the admission group and the social reinsertion period for the juveniles.

Birth narratives have been found to provide women with the most accessible and often utilised means for giving voice to their exploration of meaning in their births. The stories women tell of their birth come out of their pre- and post-experience bodies, reproducing society through the sharing of cultural meanings. I recruited a selection of 20 birth stories from a popular ‘mums’ Internet forum in the United Kingdom. Using structural and thematic analyses, I set out to explore how women tell the story of their body in childbirth. This project has contributed evidence to the discussion of women’s experiences of subjectivity in the discursive landscape of birth, while uncovering previously unacknowledged sites of resistance. The linguistic restrictions, sustained by the neoliberal control mechanisms on society and the self, act to shape the reality, feelings, and expressions of birthing women. Naming these silencing strategies, as I have done through the findings of this project, and celebrating women’s discourse on birth, as the explosion of birth stories across the Internet are doing, offer bold moves to challenge the muting status quo of women in birth. Reclaiming women’s language for birth and working to create a new vocabulary encapsulating the experiences of birthing women will also present opportunities for the issue of birth and women’s experiences of it to occupy greater political space with a confident and decisive voice.

The theory of ‘temporary selection’ is concerned with the variation, for fixed x, of q[x–t]+t the observed rate of mortality at age x during the t+1th year after the issue of an assurance or annuity contract. The classical view is that—apart from chance variations—q[x–t]+t increases gradually with increasing t until the effects of selection have disappeared after which time q[xx–t]+t is a constant depending on x only.Various reasons have been suggested for the persistence of temporary selection in an observed series of values of q[xx–t]+t. The chief of these are:(1) The continuing effects of an initial selection on the part of the assurance company or by the annuitant (Morgan, 1834);(2) The gradual withdrawal from assurance of healthy lives (Higham, 1851); and(3) Secular improvements in medicals election or in the self-selection of annuitants (Karup, 1903).

We evaluate an experimental program in which the French public employment service anonymized résumés for firms that were hiring. Firms were free to participate or not; participating firms were then randomly assigned to receive either anonymous résumés or name-bearing ones. We find that participating firms become less likely to interview and hire minority candidates when receiving anonymous résumés. We show how these unexpected results can be explained by the self-selection of firms into the program and by the fact that anonymization prevents the attenuation of negative signals when the candidate belongs to a minority.

A Performance Seeking Control (PSC) can realize the operations advantageous enough to accomplish the economy, safety, engine life, and environmental issues by reducing the control margin to the extremity together with selection of the control variables so that various kinds of parameters will be minimized or maximized. This paper describes the results obtained from the simulation study concerning the PSC aiming at the efficiency enhancement, power improvement, and longer engine life of a two-spool regenerative gas turbine engine having two control variables. By constructing the dynamic simulation of the engine, steady-state characteristics and dynamic characteristics are derived; then, a PSC system is designed and evaluated. It is concluded that the PSC for the gas turbine of this type can be realized by the turbine inlet temperature control.

Ants build complex nest structures by reacting to simple, local stimuli. While underground nests result from the space generated by digging, some leaf- and grass-cutting ants also construct conspicuous aboveground turrets around nest openings. We investigated whether the selection of specific building materials occurs during turret construction in Acromyrmex fracticornis grass-cutting ants, and asked whether single building decisions at the beginning can modify the final turret architecture. To quantify workers' material selection, the original nest turret was removed and a choice between two artificial building materials, thin and thick sticks, was offered for rebuilding. Workers preferred thick sticks at the very beginning of turret construction, showed varying preferences thereafter, and changed to prefer thin sticks for the upper, final part of the turret, indicating that they selected different building materials over time to create a stable structure. The impact of a single building choice on turret architecture was evaluated by placing artificial beams that divided a colony's nest entrance at the beginning of turret rebuilding. Splitting the nest entrance led to the self-organized construction of turrets with branched galleries ending in multiple openings, showing that the spatial location of a single building material can strongly influence turret morphology.

How can we be aware of ourselves both as physical objects and as thinking, experiencing subjects? What role does the experience of the body play in generating our sense of self? What is the role of action and agency in the construction of the bodily self? These questions have been a rich subject of interdisciplinary debate among philosophers, neuroscientists, experimental psychologists, and cognitive scientists for several decades. José Luis Bermúdez been a significant contributor to these debates since the 1990’s, when he authored The Paradox of Self-Consciousness (MIT Press, 1998) and co-edited The Body and the Self (MIT Press, 1995) with Anthony Marcel and Naomi Eilan. The Bodily Self is a selection of essays all focused on different aspects of the role of the body in self-consciousness, prefaced by a substantial introduction outlining common themes across the essays. The essays have been published in a wide range of journals and edited volumes. Putting them together brings out a wide-ranging, thematically consistent perspective on a set of topics and problems that remain firmly of interest across the cognitive and behavioral sciences.
