Transparenz im Journalismus

The transparency that journalists and newsrooms can produce for their audience has long been regarded as a rather marginal criterion for journalistic quality. But new transparency models??due to the interactivity, immediacy, archiving capacity and the absent limitation of space in the internet??offer greater potentials than classical instruments in print and broadcasting. In comments, web videos, blogs, twitter feeds and social networks, journalists discuss with users and publicly account for editorial decisions. Transparency is fashionable in the digital public sphere; its evaluation, however, is not clear, but ambiguous and complex. This paper conceptualizes (self-)transparency and qualitatively classifies the available instruments in a three-dimensional matrix model. This is to facilitate the analysis of problematic areas and potential conflicts: Newsrooms demonstrating open self-reflection dismiss the ideal of ??objective journalism??. Yet, transparency is not only an ethical demand, but is also supposed to strengthen trust in journalistic products because it permits quality evaluations by the audience. An experiment shows, for the first time, that self-transparency has an effect on trust in some aspects but not as a basic principle. Analysing this interdependency, we have to distinguish between transparency of process and of product as well as between different media.     

Food futures to sustain Chinese cities

China's rapid urbanization makes its cities vulnerable to prolonged drought in the interior. Food needs of the cities will sometimes exceed China's carryover stocks. Moreover, its cities are likely to become so large that even the global reserves, as presently accumulated, are inadequate. A survey of the technological possibilities considers food supplies for a world population leveling somewhere between 10–15 billions, with China making up 9–18% of the total. Today's bioscience promises a number of nutritional substitutes two or three generations hence. Once the world overcomes population growth, successors to the strategies proposed in this article should make it possible to sustain Chinese cities at an increasingly high quality of life.     

Stopping the exodus of women in science

A new study reveals that U.S. companies face a troubling brain drain: Fifty-two percent of female scientists, engineers, and technologists abandon their chosen professions. If companies understand why women drop out, however, they can create targeted interventions and head off a talent shortage.

In the air again: frequent flyer relationship programmes and business travellers' quality of life

This research explores whether frequent flyer programmes somehow add to the quality of life of the frequent business traveller (defined in this study as business flyers who had flown round trip 26 or more times in the past 12 months). A questionnaire was mailed to subscribers of a newsletter for members of frequent air and hotel programmes. Results indicated that frequent flyer programmes contribute positively to frequent business travellers' lifestyles and to their quality of life, perhaps by countervailing some of the negative aspects of frequent business travel.

Teaching Business Ethics Through Strategically Integrated Micro-Insertions

This article identifies an integrated teaching strategy that was originally developed for engineers, the so-called ‘micro-insertion’ approach, as a practical and effective means to teach ethics at business schools. It is argued that instructors can incorporate not only generic or thematic learning objectives for students into this method (i.e., the intended content of what is being taught: in our case, an underlying ethical base for doing business), but also do so via a strategically integrated approach regarding the appropriate mix and timing of these micro-insertions. With this in mind, we propose a qualitative and example-based approach that endeavors to provide a versatile way for business teachers to incorporate ethics into their general business classes. We also present a conceptual and theoretical framework that underpins this method, and we further provide a set of specific examples and a practical table that show how business instructors might integrate ethics-oriented micro-insertions into their teaching.     

Leadership in your midst: tapping the hidden strengths of minority executives

All companies value leadership-some of them enough to invest dearly in cultivating it. But few management teams seem to value one engine of leadership development that is right under their noses, churning out the kind of talent they need most. It's the complicated, overburdened but very rich lives of their minority managers. Minority professionals-particularly women of color-are called upon inordinately to lend their skills and guidance to activities outside their jobs. Sylvia Ann Hewlett, who heads the Center for Work-Life Policy, and her coauthors, Carolyn Buck Luce of Ernst & Young and Cornel West of Princeton, present new research on the extent to which minority professionals take on community service and other responsibilities outside the workplace and more than their share of recruiting, mentoring, and committee work within the workplace. These invisible lives, argue the authors, can be a source of competitive strength if companies can learn to recognize and further cultivate the cultural capital they represent. But it's hard to convince minority professionals that their employer respects and values their off-hours responsibilities. A lack of trust keeps many people from revealing much about their personal lives. The authors outline four ways companies can leverage hidden skills: Develop a new level of awareness of minority professionals' invisible lives; appreciate the outsize burdens these professionals carry and try to lighten them; build trust by putting teeth into diversity goals; and, to finish the job of leadership development, help minorities reflect on their off-hours experiences, extract and generalize the lessons, and apply what's been learned in other settings.     

Identifying relevant and irrelevant variables in sparse factor models

This paper considers factor estimation from heterogeneous data, where some of the variables—the relevant ones—are informative for estimating the factors, and others—the irrelevant ones—are not. We estimate the factor model within a Bayesian framework, specifying a sparse prior distribution for the factor loadings. Based on identified posterior factor loading estimates, we provide alternative methods to identify relevant and irrelevant variables. Simulations show that both types of variables are identified quite accurately. Empirical estimates for a large multi‐country GDP dataset and a disaggregated inflation dataset for the USA show that a considerable share of variables is irrelevant for factor estimation.     

Rural women leaders

This research project was designed to study the determinants of leadership development in rural women. The first phase of the study involved individual interviews with women recognized as leaders within a rural community. Each of the 25 rural women leaders interviewed was raised on a farm or in a community with a population smaller than 2,000. The second phase of the study was administered via Survey Monkey to 133 women using a modified version of the Review of Personal Effectiveness with Locus of control (ROPELOC) instrument, which included the key domains of interest and was expanded to include additional questions focusing on unique challenges to leadership among women living in rural communities. The project used leadership‐related community groups as an entry point to identify women across rural Kansas for the survey. The results from these two methods identified six themes: lifelong learners, bias and discrimination, self‐efficacy and overcoming barriers, community influence and social capital, leadership mentors, and expression of leadership.
