This paper identifies and examines the four stages of marketing's digitalization journey to date and the points of interest along the way. The metaphor of a journey provides a narrative through which to understand the complex changes that are occurring within the digitalization of marketing. The digital journey has no final destination yet, but it is possible to identify an origin and chart its route thus far. In reflecting on this journey, insights emerge, which pose ongoing challenges for businesses and for the marketing discipline. The digitalization of marketing provides new options for routes to markets, communication, brand building, relationship development, trialling pricing, product development, sourcing insights, as well as a platform for innovation. But, only if businesses embark on this journey, and then keep up with the pace once en route. The implications for business stemming from marketing's digital journey are detailed along with avenues for future research, to develop further understanding of digitalization. The theoretical contributions made by this paper include both a novel mapping of the complex trajectory of marketing's digitalization through a visualization and an articulation of the main four gaps in current research and practice knowledge within marketing. The gaps include the need for a strategic view, the issue of technical silos, the changing conceptions of time, and the tension between empowered consumers and their reliance on pre‐filtered information. This paper provides a critical appraisal of the digital journey so far, resulting in a distilled conceptualization and route map, which should help guide future researchers. 相似文献

Modeling Rabbit Responses to Single and Multiple Aerosol Exposures of Bacillus anthracis Spores 下载免费PDF全文

Survival models are developed to predict response and time‐to‐response for mortality in rabbits following exposures to single or multiple aerosol doses of Bacillus anthracis spores. Hazard function models were developed for a multiple‐dose data set to predict the probability of death through specifying functions of dose response and the time between exposure and the time‐to‐death (TTD). Among the models developed, the best‐fitting survival model (baseline model) is an exponential dose–response model with a Weibull TTD distribution. Alternative models assessed use different underlying dose–response functions and use the assumption that, in a multiple‐dose scenario, earlier doses affect the hazard functions of each subsequent dose. In addition, published mechanistic models are analyzed and compared with models developed in this article. None of the alternative models that were assessed provided a statistically significant improvement in fit over the baseline model. The general approach utilizes simple empirical data analysis to develop parsimonious models with limited reliance on mechanistic assumptions. The baseline model predicts TTDs consistent with reported results from three independent high‐dose rabbit data sets. More accurate survival models depend upon future development of dose–response data sets specifically designed to assess potential multiple‐dose effects on response and time‐to‐response. The process used in this article to develop the best‐fitting survival model for exposure of rabbits to multiple aerosol doses of B. anthracis spores should have broad applicability to other host–pathogen systems and dosing schedules because the empirical modeling approach is based upon pathogen‐specific empirically‐derived parameters. 相似文献

We estimate the country-level risk of extreme wildfires defined by burned area (BA) for Mediterranean Europe and carry out a cross-country comparison. To this end, we avail of the European Forest Fire Information System (EFFIS) geospatial data from 2006 to 2019 to perform an extreme value analysis. More specifically, we apply a point process characterization of wildfire extremes using maximum likelihood estimation. By modeling covariates, we also evaluate potential trends and correlations with commonly known factors that drive or affect wildfire occurrence, such as the Fire Weather Index as a proxy for meteorological conditions, population density, land cover type, and seasonality. We find that the highest risk of extreme wildfires is in Portugal (PT), followed by Greece (GR), Spain (ES), and Italy (IT) with a 10-year BA return level of 50'338 ha, 33'242 ha, 25'165 ha, and 8'966 ha, respectively. Coupling our results with existing estimates of the monetary impact of large wildfires suggests expected losses of 162–439 million € (PT), 81–219 million € (ES), 41–290 million € (GR), and 18–78 million € (IT) for such 10-year return period events.
SUMMARY
We model the risk of extreme wildfires for Italy, Greece, Portugal, and Spain in form of burned area return levels, compare them, and estimate expected losses. 相似文献664.

Management and psychology scholars are increasingly seeking to examine how organizational characteristics that contextualize leadership shape the occurrence, impact, and prevention of leader workplace aggression. However, a comprehensive review of this literature has not yet been conducted, so a systematic understanding is lacking regarding questions including: (1) when, why and how is such aggression more likely to occur; (2) how do contextual factors enable or constrain effects of these leader behaviors on employees; and (3) how can organizations proactively manage their internal dynamics to prevent or reduce such incidences? Drawing on Porter and McLaughlin's (2006) components of organizational context, I review existing leader aggression research that intersects with seven categories: (1) culture/climate; (2) goals/purposes; (3) people/composition; (4) processes; (5) state/condition; (6) structure; and (7) time. I then offer theoretical propositions for future work, which are grounded in the roles and responsibilities inherent to the nature of leadership and coupled with the changing nature of organizational life. As a result, I set the research agenda for the next decade of organizational context × leader workplace aggression studies. 相似文献

Using Berger and Luckmann's thesis (1966) on the social construction of reality as rationale, this research analyzes the death drawings of 946 university students enrolled in a Death and Dying course between 1985 and 2004 to investigate the basic constructs elicited by the word "death": dying, moment of death, after death, after life, and bereavement. Consistent with earlier research, gender, race, religion, and religiosity proved to be significant factors. As expected, personal experience with grief was strongly correlated with drawings focused on bereavement. In contrast to earlier studies, fear of death was not significantly related to a particular construct. Implications for research, education, and counseling are discussed. 相似文献

ABSTRACT This paper examines the efficacy of sexual violence prevention education (SVPE) in the USA and Australasia: areas, which have some of the worst rates for sexual violence prevalence, globally. Paradoxically, they are also at the forefront of innovations in sexual violence prevention, compared to some European countries where SVPE is virtually non-existent or at the embryonic stage, such as the UK. Drawing upon the Authors’ previous research on the delivery of SVPE in New Zealand secondary schools, and literature reviews into these innovations, the authors argue that social work education is ideally placed to develop SVPE, due to the ways that some of these innovations, coalesce with social work theory, critical andragogy, and social work values. These synergies have the potential for transnational application through the ways that they can inform SVPE in those countries where it is delivered by social workers in schools, and via the ways it can enhance the social work curriculum to improve post-qualifying practice in addressing sexual violence (SV). 相似文献

ABSTRACTApplying a feminist approach to research on ending violence against women and girls (VAWG) is critical because gender inequality is an underlying driver of VAWG, and feminist research aims to empower women and girls, as well as challenge prevailing inequalities through the research process itself. However, feminist research approaches have not historically been applied in the international development sector, although statistical evidence on what works to end VAWG is in high demand from governments and donors. In this article, we explore how researchers could practically reconcile an explicitly feminist undertaking, like ending VAWG, when accepted research practices within this field employ methods that are historically not informed by feminist praxis. We argue that quantitative research and feminist research approaches are not mutually exclusive, rather, they can (and do) overlap. Drawing on five decades of combined experience conducting quantitative studies on VAWG in low- and middle-income countries around the world, we highlight the challenges and opportunities for incorporating feminist research principles throughout the research process – from design, community engagement, data collection, analysis, dissemination, and policy influence. We draw on practical examples from research conducted in countries as diverse as Timor-Leste, Kiribati, and Sri Lanka, among others, illustrating that it is not only possible to apply feminist research principles to large-scale, quantitative survey research on VAWG, but that this should become a priority for good development practice. 相似文献

This paper presents findings from qualitative interviews with 24 young people (11–17 years) who have been referred to Children's Social Care Services in England. The paper explores young people's experiences of help seeking and their experiences of receiving help for maltreatment through statutory agencies. A central finding is the importance of relationships for young people when seeking and receiving help. It is through trusting relationships with professionals that young people are most likely to disclose maltreatment and/or engage with services. The paper concludes that young people's expectations and needs are not always met by the current safeguarding system and that the system needs to become more child‐centred if it is to address the concerns maltreated young people have consistently voiced through research. 相似文献

Abstract This paper establishes the key factors influencing functional solidarity—the material and emotional support mid‐life New Zealanders provide to an ageing parent or in‐law. Using the theoretical framework of intergenerational family solidarity, empirical analysis draws on the 1997 Transactions in the Mid‐Life Family survey of individuals aged 40–54. Results indicate that mature, adult children with no partner and living far from their parent are the least likely to provide emotional and in‐kind help and will be more hesitant to offer emotional support to in‐laws compared to their own parents. Adult children of Christian background, and possibly those who are homemakers and not employed, are more likely to provide in‐kind help, but those in rural areas are less likely. Surprisingly, ill health, a large household, being employed, and continuing to provide help to a young adult child who has left home do not necessarily hinder the respondent in helping an ageing parent. The argument that intergenerational relations are increasingly subject to compromise as mid‐lifers face unprecedented demands for support from other generations needs critical consideration. Further analysis should consider the cultural significance of intergenerational transactions, and how they may be influenced by the cognitive‐affective dimensions of intergenerational family solidarity. 相似文献

The business of keeping ‘Native eating houses’ has roots in the earliest days of the mining camp on the Witwatersrand and for the past century Native eating houses have constituted an important institution in the everyday lives and experience of the city's working classes. The task in this paper is to reconstruct the emergence, rise and recent demise of the Native eating house trade in Johannesburg. Issues of concern include the struggles surrounding early licensing and organization of eating houses; locational conflict over eating houses as noxious facilities; and, the progressive decline of the trade with the growth and strengthening of new competitive food sources for Black workers in Johannesburg. 相似文献
