Line management involvement in coaching: Help or hindrance? A content analysis study
Authors: Ogilvy Helen , Ellam-Dyson Vicky
Published: January 2023

Objectives:

This study investigated the involvement that line managers have when their direct reports are receiving coaching from either an internal or external coach; what line managers and coachees report hinders and facilitates line management involvement; and in what ways does line management involvement affect the outcome of coaching.

Design:

A cross-sectional design was used to explore coachees’ and line managers’ perceptions of line management involvement, as well as facilitators and barriers to their involvement. Content analysis was used to code the data.

Method:

18 coachees and 12 line managers participated in semi-structured interviews. Content analysis revealed that the involvement of line managers varied.

Results:

Factors reported to inhibit involvement included cognitions that it was a personal process, and management involvement was not necessary. Factors reported to facilitate involvement included managers’ beliefs that coaching was valuable and their understanding of how coaching worked within their organisations. Line management behaviours found to facilitate coaching comprised five clusters: supporting, collaborating, informing, management style and challenging. Behaviours found to hinder coaching comprised two clusters: restrictive and passive.

Conclusions:

This study provides a useful insight into factors that influence line management involvement, the type of management behaviours that facilitate and hinder coaching outcomes, and the consequences for transfer of learning.
An integrated model of goal-focused coaching: An evidence-based framework for teaching and practice
Authors: Grant Anthony M.
Published: January 2023

There is a considerable body of literature on goals and goal setting in the psychological literature, but little of this has found its way into the scholarly coaching literature. This article draws on the goal-setting literature from the behavioural sciences. It discusses a range of approaches to understanding the goal construct, presents a definition of goals relevant to coaching, and details a new and comprehensive model of goal-focused coaching that can be helpful both in teaching and in applied coaching practice. It also outlines new empirical research that highlights the vital role that coaches’ goal-focused coaching skills play in determining successful coaching outcomes. This preliminary research suggests that the use of a goal-focused coaching style is more effective than a ‘common factors’ or person-centred coaching style in facilitating goal attainment in coaching. It is argued that, by understanding the different types of goals and their relationship to the process of change, professional coaches can work more efficiently with their clients, helping them to achieve insight and behavioural change that enhances their workplace performance, their professional working lives and, most importantly, their personal well-being and sense of self.
Back to basics II: How the research on attachment and reflective-self function is relevant for coaches and consultants today
Authors: de Haan Erik
Published: January 2023

Purpose:

In this study the phenomenon of reflective-self function is explored in terms of its historical understanding – just as the phenomenon of transference was explored in terms of its historical understanding in an earlier instalment (De Haan, 2011). As will be shown, reflective-self function is not only demonstrably linked to secure attachment, it is increasingly held to be at the core of the process and outcome of helping conversations.

Design/Methodology:

This contribution offers a historical summary of the main breakthroughs in attachment research, showing how (in-)secure attachment can be measured reliably and how it can be linked to reflective-self function – the capacity to mentalise. This capacity is further elucidated with the help of three examples from executive coaching and team coaching.

Results:

t is shown how reflective-self function is related to secure attachment, and how mentalising can be used to co-create meaning, insight and understanding with clients.

Conclusions:

Mentalising, as understood by reflective-self function, is a helpful way into awareness, insight and empathetic understanding. Coaches would do well to foster this function within themselves and their clients.

Mindfulness-based coaching: Conceptualisation, supporting evidence and emerging applications
Authors: Virgili Mario
Published: January 2023

Purpose:

The present paper reviews the scholarly literature on mindfulness and coaching and explores the potential contributions to coaching psychology of empirically supported intervention approaches that are based on or incorporate mindfulness concepts or practices.

Method:

The main psychological mindfulness intervention approaches are described and their effects with non-clinical populations are reviewed. Evidence is then documented to suggest emerging applications of mindfulness interventions to coaching psychology.

Results:

The evidence reviewed suggests that mindfulness may enhance the well-being and effectiveness of coaches who have a personal practice of mindfulness; improves the well-being and psychological functioning of clients who are taught mindfulness skills; offers a rich repertoire of evidence-based techniques and strategies for facilitating change; and may contribute to theoretical base of coaching psychology, particularly with regards to understanding the process of individual change.

Conclusions:

This paper makes suggestions for coaching practitioners, discusses practical guidelines for integrating mindfulness into the practice of coaching, and makes recommendations for future research.
Dealing with the issue of student stress: Is mindfulness a solution?
Authors: Isham Aleksandra Eriksen
Published: January 2023

Many students experience high levels of stress which may adversely impact their health, life satisfaction, and academic performance. In the search for ways to reduce student stress, mindfulness has shown promising results. This article summarises findings on the effects of mindfulness-based interventions on student stress and related outcomes. It also highlights some issues that require further attention in order to advance our understanding of how mindfulness may benefit students experiencing stress.
Just how reliable is your internal reliability? An overview of Cronbach’s alpha (α)
Authors: Robertson Olly , Scott Evans Michael
Published: January 2023

Cronbach’s alpha (α) is the most widely used statistic denoting a scale’s internal reliability. Higher internal reliability is associated with greater confidence in the scale and the associated conclusions made from the results. Cronbach’s alpha is often used without consideration of the factors which may mediate coefficient statistics. The current report provides suggestions for future authors to improve their understanding of, inferences made from, and writing about Cronbach’s alpha.
How do Mature Students Returning to University Via Online Learning Experience the use of Time?
Authors: Pal Mia
Published: January 2023

Motivated by goals ranging from self-actualisation to career development, mature students (i.e. aged 21 or older) are confronted with an array of varying pressures and challenges during their return to university, many of which stem from time and the perception of its waning abundance. Whereas young undergraduate students may be more accustomed to pre-set schedules as they have freshly transitioned from school to university, mature students returning to university in the online environment are accompanied by additional of demands on their time, including work and family. As maturity and adult responsibilities are found to magnify temporal pressures, mature students’ experience of time in education may be distinctly different from that of the younger students. With a dearth of research addressing the experience of time and temporal attitudes in mature students, understanding the challenges encountered by these students may contribute positively to finding new modes of time management. Several directions for further research are discussed and implications of how mature students returning to university are affected by their use of time are outlined.
Transformative feminist leadership from inside the university
Authors: Clark Dessie Lee , Bauchspies Wenda K. , Nawyn Stephanie J.
Published: January 2023

As universities grapple with institutional change that tackles gendered and sexual violence, feminist academic leadership is crucial to effecting that change. We use as a case example the Center for Gender in Global Context (GenCen) at Michigan State University to explore the opportunities and limitations of feminist administrators leading campus movements challenging sexist, racist and heteronormative cultures at a university in crisis. We aim to contribute to the emerging literature on gendered organisations and feminist leadership to place it into dialogue with the everyday world of leadership and practices of an organisation committed to feminist principles and social justice.
The families in psychology project: Restructuring the field of psychology through inclusive leadership that recognises the importance of psychologists’ personal identities as parents
Authors: Grassetti Stevie N. , Pereira Lila , Wilhelmi Breanna
Published: January 2023

The identity of ‘mother’ is incompatible with the masculinist structure of academia and the professional identities of ‘psychology trainee’ or ‘academic psychologist’ as they are currently conceived. Supporting mothers as psychology trainees and early career psychologists in academia may aid in generating innovative solutions to problems in the field. Accordingly, the Families in Psychology Project (FIPP) was developed as a grassroots network to lead the field of psychology in supporting trainees and early career professionals to integrate personal and professional identities. This leadership is particularly needed at this time, when women are the majority of students matriculating from psychology graduate training programmes and when the demographic make-up of the psychological workforce is more diverse than ever before. The current commentary reviews literature to provide a rationale for why the FIPP is necessary, further describes the FIPP, and identifies specific ways by which the FIPP supports trainees and early career professionals who are parents.
Leaning in… by taking a stand, or the socio-historical preconditions for women’s leaderliness
Authors: Boisseau Tracey Jean
Published: January 2023

Beginning with a review of some widely-circulated studies of social barriers inhibiting women’s cultivation of the self-esteem and confidence upon which leadership depends, the heart of this essay intentionally resembles intergenerational storytelling. This self-conscious daughterly narrative draws attention to the intersectional factors, and puts into historical perspective, a working-class mother’s striving in the 1970s and 1980s to achieve authorised presence as a leader. A series of vignettes chronicling her standing up with and for others discloses a structural explanation for the transformation in women’s sense of self permitting a perceptible acceleration in the general emergence of women leaders in the US context during the last quarter of the twentieth century.
‘Feminazis’: A feminist poststructuralist discourse analysis into the mainstream media’s representations of feminist activism
Authors: Brannan Danielle
Published: January 2023

Using a feminist poststructuralist discourse analysis (FPDA) this research examines discourses surrounding feminist activists within mainstream Western online media articles. The mainstream media can be accused of portraying feminism and its goals negatively (Scharff 2009), often leading to negative consequences regarding identification with the feminist movement (Callaghan et al., 1999). To examine these discourses within mainstream media, 50 articles relating to the Women’s March on Washington were sampled from US and UK online newspaper sites. The findings of this research suggest that although there are both positive and negative discourses surrounding feminist activism within mainstream media, a large proportion were negative, including discourses of ‘feminism is fractured’, ‘hashtag activism’ and ‘What about the men?’ Discussions around intersectionality (including race), social media and men within feminism were seen within these overarching discourses and throughout the research the possible implications of these negative discourses surrounding feminist activists is discussed.
How do women make sense of their experiences with pornography? A thematic analysis
Authors: Lucey Catherine , Malson Helen
Published: January 2023

While pornography is increasingly widespread and accessible, women’s experiences with or views about it are seldom recognised or investigated. In this paper we explore how women make sense of their experiences with pornography. The analysis is based on data collected through qualitative questionnaires completed by 31 women. The data were analysed qualitatively using thematic analysis within a critical realist framework resulting in three key themes focusing on (1) contextualised experiences of porn, (2) female body norms and (3) gender power relations in porn. Our analysis illustrates some of the complexities in women’s experiences of and perspectives on porn and, we argue, indicates a need to view these experiences in the contexts of wider cultural ideologies of sex and gender.
Challenging the lack of BAME Authors in a Psychology Curriculum
Authors: Jankowski Glen , Sandle Rowan , Brown Merissa
Published: January 2023

Decolonising psychology curricula faces substantial anti-racist inertia and a history of ‘using data limitations as an excuse not to push ahead’ (NUS & Universities UK, 2019; p.35). We report on a targeted curriculum decolonisation project at a British university. We quantitatively coded the identifiable ‘race’, gender and nationality of the authors set as reading at the beginning (in 2015–16) and three-years after the project began (in 2019–20). Our analysis revealed no significant change in the dominance of Globally Northern (95 per cent), white (95 per cent) and male (57 per cent) authors over time. Indeed, there were more White, male authors named John than BAME-female and male authors, of any name, collectively. We call on organisational bodies to promote decolonisation as part of course re-accreditation converging with staff’s interest.
Team building interventions in sport: A meta-analysis
Authors: Martin Luc J. , Carron Albert V. , Burke Shauna M.
Published: January 2023

A meta-analysis of team building interventions in sport was completed. Seventeen studies containing 180 effect sizes were retrieved. The overall effect (Hedges g) was .427. Analyses of possible moderator variables showed the largest effect sizes were in interventions where: (a) non-experimental designs were used (g=.474); (b) the data were unpublished (g=.539); (c) goal setting only was used (g=.714); (d) the coach/manager directed the delivery (g=.446); and (e) the teams were at the university level (g=.482). Finally, team building had the greatest influence on cognitions (g=.799).
Self-determination theory and the darker side of athletic experience: The role of interpersonal control and need thwarting
Authors: Bartholomew Kimberley J. , Ntoumanis Nikos , Thøgersen-Ntoumani Cecilie
Published: January 2023

Although research guided by self-determination theory has explored the conditions (i.e. autonomy support) and psychological processes (i.e. need satisfaction) that foster healthy development and effective functioning in athletes, very little research has considered the potential role of interpersonal control and psychological need thwarting in the development of athlete ill-being. To address these limitations, two new questionnaire measures were developed: the Controlling Coach Behaviours Scale and the Psychological Need Thwarting Scale. Subsequent studies revealed that need satisfaction was predicted by autonomy-supportive behaviours whilst need thwarting was better predicted by coach control. In turn, athletes’ perceptions of need satisfaction predicted positive outcomes (i.e. vitality and positive affect) whereas need thwarting consistently better predicted maladaptive outcomes (i.e. disordered eating, burnout, depression, negative affect, physical symptoms, and perturbed physiological functioning). Such findings have important implications for the operationalisation and measurement of interpersonal styles and psychological needs both in sport and in other life domains.
Experience of working in an elite sports academy: A case study in professional cricket
Authors: Cotterill Stewart
Published: January 2023

Over the past 10 years there has been a significant increase in the number of sports adopting a more formalised, and increasingly well-funded, approach to talent development through professional sports clubs. As a result there are increasing opportunities for sport psychologists to work at this level. The purpose of this article is for the author to both share and reflect on experiences of providing sport psychology support in a professional cricket academy over a four-year period. In particular, the approaches adopted, and the effectiveness of the profiling techniques and tools used are explored. This article also seeks to explore the challenges that face a practitioner working in this developmental environment and the importance of developing good working relationships with other members of the support staff and coaching teams.
An existential approach to Authentic Leadership Development: A review of the existential coaching literature and its’ relationship to Authentic Leadership
Authors: Fusco Tony , O’Riordan Siobhain , Palmer Stephen
Published: January 2023

Authenticity is a key concept within Existential thought and practice, yet despite the growing interest in the field of Authentic Leadership, very little has been written that brings together these two fields. This review explores the existing work that does attempt to bridge these two areas, specifically considering how Existentialism might relate to the actual development of Authentic Leadership. It examines the tension behind the two opposing epistemologies of science’s rationalist approach to Leadership and Authenticity and philosophy’s phenomenological perspective. It argues the effectiveness of an existential approach to Authentic Leadership Development and proposes a phenomenological model of Authentic Leadership Coaching and illustrates how this might address the key existential issues pertinent to Authentic Leadership such as authenticity, values, meaning, purpose and finitude.
Increasing leaders’ self-concept-clarity in the authentic leadership coaching group
Authors: Fusco Tony , O’Riordan Siobhain , Palmer Stephen
Published: January 2023

Introduction:

It is suggested that authentic leaders can be distinguished by four self-related characteristics: ‘the salience of the leadership role in their self-concept, the level of self-concept clarity, the extent to which their goals are self-concordant, and the degree to which their behaviour is consistent with their self-concept’ (Shamir & Eilam, 2005, p.399). The aim of this research was to establish if and how authentic leadership group-coaching impacts a leader’s self-concept and self-concept clarity.

Design:

25 senior leaders participated in one of five authentic leadership coaching groups run over a two-year period. Each group met one day a month over three months to discuss how their past/present/future domains influence their leadership practice. The Self-Concept Clarity Scale (Campbell, Trapnell, Heine, Katz, Lavalle & Lehman, 1996) was administered at the beginning of day one and at the end of day three to see if there was any difference between pre-coaching and post-coaching scores.

Results:

Paired sample t-tests were conducted on the questionnaire data and results showed both statistical significance (p<.001) and a large Cohen effect size (d=1.01).

Conclusion:

This paper considers the relevance of the self-concept in the context of authentic leadership development and the results suggest that authentic leadership group-coaching works at a sufficiently deep level to increase participant’s self-concept-clarity. It examines how group-coaching can help individual’s achieve a greater clarity of their self-concept and proposes a combination of social psychology theories to explain why this group format may be so effective.
The impact of peer-to-peer coaching on self-esteem, test anxiety and perceived stress in adolescents
Authors: Warner Nicola , Budd Mary-Jane
Published: January 2023

Schools are increasingly using peer support programmes to support students. This study will explore the effectiveness of peer-to-peer coaching on increasing self-esteem and reducing test anxiety and perceived stress in sixth form students. Fifty-five participants took part in the study. IGROW, a variation of the GROW coaching model, was used to structure a coaching intervention for 27 students, with 28 students receiving no coaching intervention. There was a significant improvement in self-esteem post-intervention for males regardless of group. The coaching group significantly reduced in test anxiety. There was no significant impact of coaching on perceived stress. Further research may determine whether peer coaching may be a beneficial low-cost method to support students during stressful periods.
Achieving Equity in Graduation Rates and Other Indicators of Success for Indigenous Learners in Canada
Authors: Louie Dustin William , Prince Leona
Published: January 2023

This research project was designed to attend to inequity for Indigenous students, communities, and knowledges in a northern British Columbian district. The aims of the article are to share the systemic and individual transformation for Indigenous learners and their families based on the strengths and barriers they perceive in the system. Presented here are the results of extensive engagement with students, parents or guardians, teachers, administrators, and Indigenous communities that have led to novel practical approaches to governance, policy, programmatic design, and practice in a mainstream school district, resulting in improved school experiences for Indigenous learners. Through this research we illuminate the voices of Indigenous students and show how they guided the pursuit of equity in a Canadian school district. We examined the unconscious colonial agenda to understand how it emerges visibly and invisibly in a given context (Louie, 2020), while simultaneously creating distinct responses emerging from the teachings of Indigenous stakeholders and rights holders. Internal and external pressures on school districts often result in urgent demands for transformation, or at minimum, the urgent shift in perception of transformation (Daigle, 2019), but real and sustaining change cannot be rushed, borrowed, or created in isolation from the rest of the system.
Impact of School Climate on Teachers’ Workplace Organizational Deviant Behavior at High and Higher Secondary School Level
Authors: Ali Wahab , Ullah Hakim , Ayaz Muhammad
Published: January 2023

This study aimed to investigate the impact of school climate on teachers’ workplace organizational deviant behavior. The main objectives of the study were to analyze the impact of principal behavior, teachers’ behavior towards their colleagues, school safety and school resources on teachers’ workplace organizational deviant behavior. The study was descriptive in nature. The population of this study consisted of all the teachers of government high and higher secondary boys’ schools of district Nowshera, Peshawar and Mardan. Using simple random sampling technique, 367 teachers were selected as a sample size from both urban and rural areas of the three sampled districts. Self-designed structured questionnaires were used to collect data from teachers about school climate and organizational deviant behavior of teachers. Confirmatory factor analysis technique was used and all the 5 variables were correlated with one another. Using structural equation model by AMOs, 4 null hypotheses were tested and all the null hypotheses were rejected. Data analysis revealed that school climate had significant impact on teachers’ workplace organizational deviant behavior. In general, it was concluded that those schools where school climate was positive and improved, there teachers’ behavior was less deviant. On contrary, teachers’ behavior was more deviant in those schools where climate of the school was adverse and negative. Moreover, climate of urban schools was improved as compared to climates of rural schools and teachers’ behavior was less deviant in urban schools as compared to teachers’ behavior in rural schools. Less experienced teachers were less deviant as compared to more experienced teachers. It was recommended that school climate should be improved which would minimize organizational deviance of teachers.

Registro de algunas especies de áfidos (Hemiptera: Aphididae) en el Parque Nacional Laguna San Rafael
Authors: Ramirez Claudio C.
Published: January 2023

Neuquenaphis E. E. Blanchard, es un género endémico sudamericano de áfidos (Hemiptera, Aphididae, Neuquenaphidinae) que se hospeda casi exclusivamente sobre especies de árboles del genero Nothofagus (Nothofagaceae). La mayor parte de la información existente respecto de esta primitiva asociación proviene de estudios realizados en la zona centro-sur del país, en tanto existe escasa información concerniente a la zona austral. Con el propósito de actualizar el numero de registros de este grupo de áfidos, en el área del Parque Nacional Laguna San Rafael (PNLSR), Coyhaique, se estudiaron las especies de áfidos asociados al estrato boscoso dominado por Nothofagus nitida y Nothofagus betuloides. Se logro determinar la presencia de individuos de Neuquenaphis schlingeri Hille Ris Lambers y Neuquenaphis chilensis Essig hospedando sobre Nothofagus nitida. No se detectaron áfidos en Nothofagus betuloides. Se registro también a Neuquenaphis valdiviano Carrillo sobre Gunnera magallanica. Sobre otras especies de plantas vasculares se registraron otros géneros de áfidos, constituidos principalmente por especies introducidas. Estos registros se comparan con aquellos realizados para otras zonas del país.
Diversidad y abundancia de anfibios en el Parque Nacional Laguna San Rafael (XI Región, Chile)
Authors: Díaz- Páez Helen , Williams Clair , Griffiths Richard A.
Published: January 2023

La fauna de vertebrados de Chile, se encuentra afectada por graves problemas de conservación, donde, los anfibios con su alto grado de endemismo forman parte de los grupos más vulnerables. El estudio se llevo a cabo entre el 23 enero al 9 de febrero de 1999 y fue conducido en la orilla oriental, sur y occidental de La Laguna San Rafael. El tiempo usado en cada sitio fue de 4-6 días. Los tres sitios son Glaciar (orilla oriental), San Quintín (orilla del sur) y El Canal (orilla occidental). Se usaron cinco métodos de estudio: Encuentro visual (VES), Búsqueda de refugio, Trampa de caída (pitfall). Estudio auditivo, y Trampas de botella en ambos hábitats terrestres y acuáticos. En general, VES y búsqueda de refugio fueron los métodos de estudio más productivos. Se determino la presencia de seis especies de anfibios: Batrachyla aniartandica, B. taeniata, B. nibaldoi, Hylorina sylvatica, Eupsophus calcaratus y Bufo variegalus. Los ensambles y abundancias relativas variaron entre los sitios. El Canal es el sitio de mayor riqueza especifica, con un total de cinco especies encontradas. Las especies difirieron en su rango de distribución: B. aniartandica, B. taeniata y E. calcaratus presentaron amplia extension, con presencia en los tres sitios; B. nibaldoi se encontró en dos de los sitios, e H. sylvatica y B. variegalus estaban cada uno en un sitio solamente. Adicionalmente, se documenta la presencia de B. nibaldoi, especie recientemente descrita y que no había sido registrada previamente dentro del Parque Nacional Laguna San Rafael (PNLSR). Los anfibios presentaron diferencias en los hábitats seleccionados; B. taeniata y B. nibaldoi abundaron en hábitat de matorral; B. variegalus aparece asociado a las áreas de turberas; mientras que B. aniartandica y E. calcaratus habitan el bosque. Respecto a H. sylvatica, es impreciso dar antecedentes acerca de su preferencia de hábitat, dado la baja tasa de capturas. La captura de más de 300 individuos en nueve días de estudio, incluyendo el registro de una especie no conocida previamente en el parque, indica que el PNLSR es un importante hábitat de anfibios.

Interacción entre hombre y fauna extinguida en la transición Pleistoceno-Holoceno en Chile centro-sur: una revisión
Authors: Labarca E. Rafael , López M. Patricio , García P. Christian
Published: January 2023

La interacción entre fauna extinguida y el hombre durante la transición Pleistoceno-Holoceno en Chile centro-sur (latitudes 31 °S y 42°S), ha carecido de trabajos sistemáticos o programas de investigación, lo que se ve reflejado en la presencia de tan sólo cuatro sitos aislados de características muy disimiles entre si. El presente trabajo examina la literatura producida en tomo a estos sitios, aportando información de estudios recientes, reinterpretando en algunos casos la evidencia «clásica» a la luz de nuevas concepciones teóricas. Se observa que de todo el variado elenco faunistico que habitaba la región durante este momento, sólo un reducido número de especies fue efectivamente utilizada por los primeros pobladores de la región, al parecer de manera no intensiva, lo que no explica el gran número de especies que desaparecieron comenzado el Holoceno. Se plantea la necesidad de abordar la problemática de los primeros habitantes de la región de forma mucho más flexible, revalorando el papel de la recolección y la caza de fauna moderna, situando a la fauna extinguida sólo como una opción a considerar dentro de estrategias de subsistencia mayores, las que requieren ser investigadas.

Liolaemus frassinettii, nueva especie de lagartija para los Altos de Cantillana, Región Metropolitana (Reptilia: Sauria)
Authors: Núñez Herman
Published: January 2023

Se describe a Liolaemus frassinettii como nueva especie para la ciencia. Este reptil habita en la cordillera de la Costa, en la cima del cerro Cantillana. La especie está morfológicamente relacionada con Liolaemus valdesianus de la cordillera andina, restringido al valle del río Maipo; se puede adjudicar al grupo "elongatus" de distribución cisandina. Las propuestas de especiación en valles y montañas podrían explicar la existencia de esta especie relacionada a un grupo hasta ahora sólo conocido de ambientes andinos. Esta especie se diferencia de las demás pertenecientes al grupo "elongatus" por la presencia de grandes escamas infralabiales que la diferencian además de todas las especies del género, en Chile al menos.

En este estudio se evalúa el imposex en dos poblaciones de Acanthina monodon del sur de Chile sometidas a distintos niveles de actividad antropogénica. Una de las localidades fue escogida para evaluar específicamente el aumento o disminución de imposex considerando datos publicados previa-mente. En cada sitio se recolectaron 103 ejemplares cuantificándose tres índices de imposex: porcentaje de hembras con imposex, longitud relativa del pene (RPLI) y tamaño relativo del pene (RPSI). En Metri, donde la actividad humana es considerable, el 48,6% de las hembras examinadas presentó imposex mientras en isla Victoria, donde la intervención es escasa, ninguna de las hembras evidenció el fenó-meno. El porcentaje observado en Metri aumentó en más de ocho veces comparado con un estudio pre-vio de 1999. Los valores de RPLI y RPSI también fueron más altos. Los resultados sugieren un aumento en la concentración de contaminantes en el ambiente o en el tiempo de exposición de los moluscos a es-tos compuestos en esta localidad

Authors: Ferrú Marcos A. , Elgueta Mario
Published: January 2023

Se entrega una lista actualizada de las especies de coleópteros presentes en las regiones de Arica y Pari- nacota y de Tarapacá; para cada una de las especies se agrega su distribución geográfica conocida a nivel mundial y detallando para el caso de Chile, especialmente para las regiones antes señaladas, los registros de localidades por provincia y de acuerdo a la actual división administrativa del país. Para las regiones estudiadas se señala la presencia de 333 especies de coleópteros, pertenecientes a 32 familias; sólo seis familias (Carabidae, Coccinellidae, Curculionidae, Scarabaeidae, Staphylinidae y Tenebrionidae) contribuyen con más del 63% del total de especies registradas, siendo Tenebrionidae la que presenta mayor número (82 especies). Se registra por primera vez la presencia en Chile de representantes de los género Anchonoderus (Carabidae), Rolla (Staphylinidae) y Zonitis (Meloidae), además de Conode- rus amplicollis Gyllenhal (Elateridae), Xyletineurus bombycinus (Erichson) (Ptinidae) y Praocis peltata Erichson (Tenebrionidae).
Geosphaeropterus, nuevo género de Tropiphorini (Coleoptera: Curculionidae) de Chile, con descripción de tres nuevas especies
Authors: Elgueta Mario
Published: January 2023

Se describe un nuevo género y tres nuevas especies, propias de dunas costeras e interiores del norte de Chile; estas especies se relacionan con representantes de Strangaliodes, pero las diferencias en caracteres morfológicos externos e internos justifi can la separación de ellas en un nuevo género.

Durante más de medio siglo, Luis Peña y posteriormente su colaborador Alfredo Ugarte, reuni- eron toda la información conocida sobre mariposas en Chile para publicar la primera obra completa sobre estos insectos en el país (Peña y Ugarte, 1997). Su trabajo resume el conocimiento acumulado hasta el final del siglo XX. Desde entonces, los autores han realizado trabajos adicionales, resultando en la descripción de numerosas especies nuevas, así como también, el establecimiento de nuevos reg- istros de especies para Chile, especialmente en las familias Lycaenidae y Nymphalidae (Satyrinae). La lista de estas dos familias, aún no está completa, pues varias especies nuevas se publicarán pronto y aparecerían en la segunda parte de este documento. El presente trabajo comprende cuatro familias y se actualiza la lista de mariposas de Chile a través de: 1) la descripción de una nueva especie de Pieridae, 2) la descripción de una nueva subespecie de Nymphalidae (Heliconiinae), y 3) la adición de un total de 10 especies y dos subespecies.
La presente lista actualizada incluye la distribución regional (D) y por primera vez, el período de vuelo (FP) y el estado de conservación (C). Muchas especies de mariposas chilenas son de especial interés para la conservación. Varias ya habrían desaparecido en algunas localidades. El acelerado ritmo del desarrollo y la conversión y pérdida del hábitat, ponen en peligro a muchos de estos insectos. Los autores hacen un llamado a las autoridades para salvar las mariposas de Chile.

Excavaciones Arqueológicas en el Cuartel General del Cuerpo de Bomberos de Santiago, Chile

Se realizaron excavaciones en el patio del Cuartel General de Bomberos de Santiago con el objetivo de localizar restos arquitectónicos y artefactuales de la presencia inca en el sector de Plaza de Armas, de la ciudad de Santiago. Se encontró evidencia cerámica de ocupación Tawantinsuyu en distintos niveles, los que aparecieron mezclados con restos coloniales, situación que impidió determinar si correspondieron a restos prehispánicos, contemporáneos a los primeros conquistadores españoles o a ambos.

Con respecto a las ocupaciones coloniales, las excavaciones efectuadas entregaron material colonial coherente con la información documental registrada para los propietarios de las manzanas colindantes a la Plaza Mayor, a saber, gente de la clase alta de origen hispano, representada por mercaderes, militares de alto rango y autoridades (gobernadores). La presencia de restos de bienes de lujo, como porcelana china, mayólica, vidrio europeo, vestimentas de lujo (presencia de botones de bronce) y adornos apoyaron esta presunción. Los restos óseos indicaron que la carne consumida era mayoritariamente cabra, seguida por algunas aves de corral.

Durante los siglos posteriores, el sector siguió siendo utilizado por personas de la elite santiaguina, a juzgar por la elevada presencia de bienes de prestigio. Finalmente, los restos de un acueducto abovedado confirmaron que la propiedad estuvo inserta en las medidas sanitarias de mediados del siglo XIX.

The transforming mechanism of pumping units is a four-link articulated mechanism, made according to symmetrical and asymmetric kinematic schemes. With a symmetrical scheme, the center of rotation of the crank is on a straight line passing through the points corresponding to the extreme positions of the connecting rod and balancer articulation. All other cases correspond to the asymmetric scheme. Currently, in accordance with the existing methodology for designing a converting mechanism of a symmetrical circuit, the kinematic ratios r/k and r/l are used as initial data - the ratio of the crank radius to the length, respectively, of the rear arm of the balance bar and connecting rod. It is considered more preferable and practical to design a mechanism according to predetermined output parameters. As a result, we find that the overall dimensions of the converting mechanism of domestic pumping units of a symmetrical scheme (length by 45…60%, and height - 25…30%) are less than those of foreign pumping units of an asymmetric scheme. The developed technique allows to compare the technical and operational indicators of pumping units made according to various kinematic schemes. Keywords: connecting rod; balancer; cranks; traverse; radius; mechanism.

The region’s oil fields are located within the South Caspian oil and gas basin, on the territory of the Absheron Peninsula and the adjacent waters of the Caspian Sea. Here are more than 80 oil and gas fields. To this end, this article presents the geological structure of the South Caspian Depression, as well as the Absheron-Balkhan zone. The analysis of oil and gas content and modern seismicity of the Caspian Sea is carried out. Increasing recoverable oil reserves, reducing water cut, increasing or even stabilizing production at this stage is the number one task for the oil industry. It has been established that in recent years, the level of seismic activity of individual sections of the Caspian water area has increased, and the amount of seismic energy released in the Central Caspian has increased by several dozen times, it can be assumed that the change in oil production in many offshore fields in the northern part of the Absheron-Balkhan fold system is associated with strong (ml>3.0) earthquakes characterized by fault-shear type of movements. Keywords: Caspian sea; oil and gas deposits; earthquake source mechanisms.
