Mortality rates of the Alpine Chamois : the influence of snow-meteorological factors

Especially for animals inhabiting alpine areas, winter environmental conditions can be limiting. Cold temperatures, hampered food availability and natural perils are just three of many potential threats that mountain ungulates face in winter. Understanding their sensitivity to climate variability is essential for game management. Here we focus on analyzing the influence of snow and weather conditions on the mortality pattern of Alpine chamois. Our mortality data are derived from a systematic assessment of 6,500 chamois that died of natural causes over the course of 13 years. We use population- and habitat-specific data on snow, climate and avalanche danger to identify the key environmental factors that essentially determine the spatio-temporal variations in chamois mortality. Initially, we show that most fatalities occurred in winter, with a peak around March, when typically snow depths were highest. Death causes related to poor general conditions were the major component of seasonal variations. As for the interannual variations in mortality, snow depth and avalanche risk best explained the occurrence of winters with increased numbers of fatalities. Finally, analyzing differences in mortality rates between populations, we identified sun-exposed winter habitats with little snow accumulation as favourable for alpine chamois

Four keys to Chilean culture : authoritarianism, legalism, fatalism and compadrazgo

Chilean culture is said to be part of a wider Hispanic American culture that shares many traits (see Godoy et al. 1986; Subercaseaux 1999; Valdivieso and which could be identified as an identity with a Latin American sense (see Rodríguez et al. 2001). In this sense, though it may seem as if any attempt to describe or analyse particular operating elements, processes, systems and structures were a useless task, the nature of identity makes it a multiple and symbolically contradictory phenomenon, with relevant contextual 'consequences' and particularities that help identify a collective imaginary that can be associated with what means to be Chilean. As such, the importance of meaning lies not on its production but rather on its reception; therefore, we aim to address some elements of the reception that we have identified as 'critical' or 'diagnostic'. By 'critical', we mean those elements, which absence would substantively modify what is collectively associated with Chilean culture and by 'diagnostic', we suggest the possibility they offer of exploring meaningful contextual traits. In order to contextualise our analysis, we will focus on three discursive levels, namely organisational/structural, cultural/ideological and identity. At the organisational/structural level, we will make reference to structure and aesthetics in the broader sense of social context as well as in public and private organisations; at cultural/ideological level, we will make reference to practices, rituals, values and behaviours; and at the identity level we will make reference to strategies individuals use to manage their social identities

HRM in Chile : the impact of organisational culture

Purpose: This paper provides insight on the influence of organisational culture on HRM practices in Chile by exploring shared meanings (basic assumptions and beliefs) and organisational models that can be identified from activities, dynamics, social relationships and behaviours. Design/methodology/approach: The paper is based on research conducted in Chile where a combination of self-completion questionnaires, semi-structured interviews and non-participant observation was carried out in a non-probabilistic sample of 46 organisations. Findings: Findings suggest that there is a shared definition of work characterised by five elements; namely, the existence of great work pressure exerted by managers; a sustained focus of upper levels on organisational efficiency as an isolated element that does not include HRM; the inexistence of worker autonomy and empowerment; the use of administrative jargon and understandings of loyalty, dedication, compliance and professionalism as desired qualities in workers. The paper argues that there are three distinct categories of cultural discourse in Chilean organisations: pessimistic/fatalistic, optimistic/maniac and pragmatic/bureaucratic. Research limitations/implications: Due to the type of sampling used, findings cannot be taken to represent the whole of Chilean organisations.Practical implications: Data presented in this paper helps to understand many of the behaviours observed in Chilean organisations, which provides HR policy-makers and practitioners with sounder foundations for designing organisational programs, policies and action plans. Originality/value: The paper presents new evidence to increase empirical body of work addressing the relationship between organisational culture and HRM in developing countries, particularly in Latin America

X-ray and Ultraviolet Properties of AGN in Nearby Dwarf Galaxies

We present new Chandra X-ray Observatory and Hubble Space Telescope observations of eight optically selected broad-line AGN candidates in nearby dwarf galaxies ($z<0.055$). Including archival Chandra observations of three additional sources, our sample contains all ten galaxies from Reines et al. (2013) with both broad H$\alpha$ emission and narrow-line AGN ratios (6 AGNs, 4 Composites), as well as one low-metallicity dwarf galaxy with broad H$\alpha$ and narrow-line ratios characteristic of star formation. All eleven galaxies are detected in X-rays. Nuclear X-ray luminosities range from $L_{0.5-7 \rm{keV}}\approx5\times10^{39}$ to $1\times10^{42}$ $\rm{erg}\rm{s^{-1}}$. In all cases except for the star forming galaxy, the nuclear X-ray luminosities are significantly higher than would be expected from X-ray binaries, providing strong confirmation that AGN and composite dwarf galaxies do indeed host actively accreting BHs. Using our estimated BH masses (which range from $\sim7\times10^{4}-1\times10^{6}~M_{\odot}$), we find inferred Eddington fractions ranging from $\sim0.1-50\%$, i.e. comparable to massive broad-line quasars at higher redshift. We use the HST imaging to determine the ratio of ultraviolet to X-ray emission for these AGN, finding that they appear to be less X-ray luminous with respect to their UV emission than more massive quasars (i.e. $\alpha_{\rm OX}$ values an average of 0.36 lower than expected based on the relation between $\alpha_{\rm OX}$ and $2500{\rm \AA}$ luminosity). Finally, we discuss our results in the context of different accretion models onto nuclear BHs.Comment: 15 pages, 15 figures, 4 tables. Submitted to Ap

Hubble Space Telescope Imaging of the Active Dwarf Galaxy RGG 118

RGG 118 (SDSS 1523+1145) is a nearby ($z=0.0243$), dwarf disk galaxy ($M_{\ast}\approx2\times10^{9} M_{\odot}$) found to host an active $\sim50,000$ solar mass black hole at its core (Baldassare et al. 2015). RGG 118 is one of a growing collective sample of dwarf galaxies known to contain active galactic nuclei -- a group which, until recently, contained only a handful of objects. Here, we report on new \textit{Hubble Space Telescope} Wide Field Camera 3 UVIS and IR imaging of RGG 118, with the main goal of analyzing its structure. Using 2-D parametric modeling, we find that the morphology of RGG 118 is best described by an outer spiral disk, inner component consistent with a pseudobulge, and central PSF. The luminosity of the PSF is consistent with the central point source being dominated by the AGN. We measure the luminosity and mass of the "pseudobulge" and confirm that the central black hole in RGG 118 is under-massive with respect to the $M_{BH}-M_{\rm bulge}$ and $M_{BH}-L_{\rm bulge}$ relations. This result is consistent with a picture in which black holes in disk-dominated galaxies grow primarily through secular processes.Comment: Accepted to Astrophysical Journal. 11 pages, 8 figure

What You Do in High School Matters: The Effects of High School GPA on Educational Attainment and Labor Market Earnings in Adulthood

Using abstracted grades and other data from Add Health, we investigate the effects of cumulative high school GPA on educational attainment and labor market earnings among a sample of young adults (ages 24-34). We estimate several models with an extensive list of control variables and high school fixed effects. Results consistently show that high school GPA is a positive and statistically significant predictor of educational attainment and earnings in adulthood. Moreover, the effects are large and economically important for each gender. Interesting and somewhat unexpected findings emerge for race. Various sensitivity tests support the stability of the core findings.High school grades; Educational attainment; Earnings; Panel data

I want to speak English like you : one woman\u27s experience teaching English to adults in Senegal

I went to Senegal, West Africa, in December 2004 because I wanted to teach English there. This was my second trip to Senegal. On my first trip one year earlier I went to practice African dance, and at that time several people asked me to teach them English. In response to their requests and my own sense of adventure, I created an English as a Foreign Language curriculum specifically designed for semi-literate Senegalese adults working in the tourist business. I spent one month in the village of Abene teaching adults and children, but specifically for this study I conducted interviews and intensive observations of two women and two men. As a result of this study I am currently building the Bolong International Library in Abene. This library will be a place where adults and children can learn English, practice literacy in French and their home languages, get help filling out official forms, and pick up donated school clothes and supplies. I am also working on recruiting adventurous teachers who want to participate in cultural exchange while teaching English in a beachside village in Africa

Reconsidering cultural entrepreneurship: hip hop music economy and social change in Senegal, francophone West Africa

The increasing interest in the cultural economy is part of an attempt to invent new industrial development strategies that comprises a capacity to transform locations. In policy-making, the cultural economy is commonly framed from an economic perspective that salutes the role of the cultural economy and the dynamics of entrepreneurship in processes of urban and regional developments. Moreover, explorations of cultural economy and entrepreneurship are mainly represented by studies of Europe and North America. This thesis departs from such a normative perspective, and critically examines the links between a situated music economy, its cultural entrepreneurs and social change in West Africa. The empirical investigation of West African hip hop musical practitioners is framed by the notion of “community of practice”. The situated practices of these cultural workers and their music production ecology are investigated – methodologically – from a grounded perspective in order to grasp the originality of their materiality and aesthetics. The empirical focus of this thesis research is Dakar, one Francophone West African urban locale, which is contrasted with the ‘test case’ site of Ouagadougou. The case study locations are ‘experientially situated’, and over seventy semi-structured interviews were conducted with a range of participants both directly and indirectly involved in the hip hop music economy. Underpinning this research is the starting point that using “community of practice” as a conceptual framework offers a theoretically informed empirical basis for situating cultural entrepreneurship in the context of the West African music economy. In response, this thesis introduces the transcultural dimension of Hip Hop to frame its radical culturalisation of the West African music economy. This is done by singling out the political, social and theoretical significance of how hip hop entrepreneurship has become a force to be reckoned within social change in Francophone West Africa: this is a significant contribution of the thesis
