How to Identify Journalists?Developing a Theoretical International Foundation for the Operationalisation of a National Comprehensive Survey of Journalists in Austria

A dozen years ago, journalists in several countries, the US, Germany, Switzerland, Austria and more, were precisely counted and socio-demographically analysed. Today there are no comparable current national surveys of journalism. For a recount of journalists nation-wide in Austria we now have to re-define whom we are searching for. Yet, a clear assignment of who is actually a journalist is not merely necessary for noble research purposes, but also for very pragmatic reasons: Being a legitimate journalist accords prestige and credibility, gives access to information, funding, legal rights, and more institutionalised privileges. We assume that it is the protracted discussion emphasising the boundaries of journalism which complicates the reflection about the core of journalism and the identification of journalists. Accordingly, we considered it necessary to first re-think the nature of journalism, closely linked to international research, and to formulate the research questions very generally, in order to develop a basis for a comprehensive survey 2019 in Austria: What is journalism? What defines a journalist today? How can journalists be identifiedand then recorded? Answers will, ideally, not only serve as a starting point for the new survey of Austrian journalists but will also provide a basis for discussion of journalism researchers in other countries. 

Ask and You Shall Receive? Gender Differences in Regrades in College

Using administrative data from a large public university, we show that male students are 18.6 percent more likely than female students to receive favorable grade changes made by instructors. Surveys of students and instructors reveal that regrade requests are prevalent and that male students are more likely to ask for regrades on the intensive margin. We corroborate the gender differences in regrade requests in an incentivized controlled experiment: we find that males have a higher willingness to pay to ask for regrades. Almost a third of the gender difference is due to gender differences in beliefs and the Big Five traits. (JEL D82, D91, I23, J16)
Cognition and CSR reactions to institutional pressures 1

Combining the principles of prospect theory with theoretical and case study evidence from Latin America, the current study sheds light on the role of managerial cognition in shaping firms’ localized vs. globalized CSR reactions towards institutional events perceived as legitimacy related losses or gains, for both MNC subsidiaries and local firms operating in developing countries. Particularly, the study proposes that MNCs react to perceptions of legitimacy losses with localized CSR and to perceptions of legitimacy gains with globalized CSR, whereas the reverse holds true for local developing country firms, acting in developing country contexts.
The Taxpayer Relief Act of 1997 and the U . S . Housing Boom ∗

In the period 1997-2007, the following developments took place in the U.S. residential housing market. First, house prices and mortgage volume increased strongly, but mortgage volume increased faster than house prices so that the loan-to-value ratio increased. Second, delinquency rates fell. We use a calibrated macro model to argue that the Taxpayer Relief Act of 1997, which eliminated taxes on capital gains from the sale of residential housing for most households, can account for a substantial part of these developments in the U.S. housing market. With higher after-tax gains from the purchase of housing, agents are less likely to default on their mortgages which increases both the demand and supply of credit for housing and hence helps us understand the simultaneous increase in the loan-to-value ratio and decline in mortgage default rates observed over the period 1997-2007.
The China Shock, Employment Protection, and European Jobs

The authors investigate the effects of Chinese import competition on transitions into and out of employment using comparable worker-level data for 14 European countries. Results indicate that, on average, Chinese imports are associated with an increased probability that employed workers become unemployed and with a reduction in worker flows from unemployment to employment. In countries with high levels of employment protection, incumbent workers are shielded against the risk of job loss due to Chinese competition, but unemployed workers’ prospects seem to be particularly negatively affected in these countries. The authors also provide evidence that the effects of increased Chinese imports differ by worker groups and the tasks performed on the job.
A revision of a traditional astronomy course through active learning

We report on the conversion of a general education sophomore-level astronomy course from traditional lecture-based methods to a more active-learning course. The course was reworked into an active-learning environment through the addition of concept-oriented group worksheets, hands-on experimental activities, and planetarium-based lessons. We reflect on the process of this transition and report on factors that led to the adoption of active learning, factors that supported the change, and barriers faced while implementing this change. We compare and contrast these findings with other case studies of instructional change and theories of adoption. In addition, student learning pre to post was measured with the TOAST and LPCI, and qualitative data was collected in the form of 35-minute semi-structured interviews with each student to investigate student learning, attitudes, and perceptions of the course as a whole.
In Vitro Control of Postharvest Spoilage Fungi Affecting Sweet Potato (Ipomoea batatas) In Ebonyi State, South-Eastern Nigeria

Postharvest fungal spoilage is one of the major constraints to sweet potato production in Ebonyi State. The study investigated the in vitro control of the postharvest spoilage fungi affecting sweet potato in Ebonyi State with single and combined extracts of Garcinia kola, Allium sativum, Zingiber officinale and Moringa oleifera via Food Poison/Radial Growth technique. Single extracts were evaluated at 50 and 100 mg/ml concentrations of each plant extract while in the assay of combined plant extract, only 100mg/ml of each plant extract was mixed to provide extract combinations at equal mixing ratio of 2 (1:1) extracts. Extracts of Zingiber officinale, Allium sativum, Moringer oleifera and Garcinia kola when used individually at a lower concentration (50mg/ml), significantly inhibited the mycelial growth of all the phytopathogens in vitro when compared to the control but gave less than 50% inhibition which ranged from 5.44 29.56%. At a higher extract concentration (100mg/ml), the inhibition obtained was significantly (P= 0.05) higher than those of the control and lower concentrations but were still less than 50% except for garlic extract effect on A. niger. However, the use of two plant extract combinations (100mg/ml concentration each) showed mainly additive and synergistic extract/pathogen interactions that resulted in increased inhibition (above 50%) across most of the pathogens, though with a few antagonistic interactions. Combinations of Allium sativum and Zingiber officinale and Allium sativum and Moringa oleifera proved the best treatment combinations with no antagonism and the broadest spectrum antifungal activity.
Early Surgery before 4 years of Age in Intermittent Exotropia

Purpose: We performed this study to evaluate the occurrence of consecutive esotropia after early surgery in the patients with intermittent exotropia less than 4 years of age. Methods: We analyzed the surgical results of 37 patients who underwent surgery before 4 years of age retrospectively. They were followed up at least more than 1 year after surgery. The orthophoria was defined as an exophoria of 0 to 12PD or an esophoria of 0 to 5PD after surgery. The consecutive esotropia was defined as an esodeviation lasting more than 3 months that needed surgical correction due to sensorial deterioration. Results: Preoperative angle of exodeviation at distance ranged from 20PD to 60PD (mean 35.19.2PD). Twenty-seven of 37 patients (75.7%) showed orthophoria after surgery in 1 year follow-up and 20 of 31 patients (64.5%) in 2 years follow-up. Five patients (13.5%) showed recurrence and 4 patients (10.8%) consecutive esotropia. Immediate postoperative overcorrection was 14.18. 7PD(0-30) in patients who were orthophoric after postoperative follow-up more than 2 years. The rate of consecutive esotropia was high in patients with an exo-angle of 30PD or more and a large amount of recession of lateral recti more than 7mm. Conclusions: This study revealed that consecutive esotropia after early surgery for intermittent exotropia less than 4 years of age was noted to the 10.8%.
Assessing and comparing the quality of wound healing with Vacuum-Assisted Closure and with conventional dressings using Wound Bed Score

BACKGROUND Delayed wound healing is a major health issue in today’s society, particularly in older population. Failure of the wound to heal causes social and financial burdens, in addition to the pain and suffering they have to undergo. ABBREVIATIONS SSG -Split Skin Grafting, VAC -Vacuum Assisted Closure, WBS -Wound Bed Score OBJECTIVES To assess and compare the quality of wound healing with Vacuum-Assisted Closure (VAC) and with conventional dressings using Wound Bed Score (WBS). MATERIALS AND METHODS It is a prospective observational study enrolling 80 patients, who were divided into two groups. First 40 patients were treated with conventional dressings, and the remaining patients treated with VAC dressings. Each patient was followed up for 30 days and assessed a total of 7 times with a time interval of 5 days. The quality of wound healing was assessed using WBS, which had 8 parameters. Healing edges, presence of slough, granulation tissue, amount of exudate, edema, peri-wound dermatitis, peri-wound fibrosis and pink/red wound bed were assessed in both the groups on Day0, Day5, Day10, Day15, Day20, Day25 and Day30, and were compared. RESULTS After analysing the granulation tissue present in the ulcers in both the groups, it was noted that at Day5, conventional group had very minimal or no granulation tissue-23(57.5%) whereas in VAC group, 26(65%) had almost half granulation tissue covered. Considering the edges of ulcers in both the groups it was noted that at Day15 and Day20, moderate healing was seen in 21(52.5%); 20(50%) subjects in conventional group and 23(57.5%) ; 22(55%)in VAC group respectively whereas at Day25 and Day30, moderate healing-17(42.5%) was seen in conventional group, but most of the subjects showed good healing in VAC group at both Day 25 20(50%) and Day3022(55%). 17(42.5%) patients in VAC group underwent definitive treatment during the study period, whereas, only 8(20%) patients in conventional dressings group underwent definitive treatment. CONCLUSIONS VAC Dressings are more efficient compared to conventional dressings, by considering the increase in granulation tissue, good healing edges and more number of people undergoing definitive treatment. -------------------------------------------------------------------------------------------------------------------------------------Date of Submission: 20-02-2019 Date of acceptance: 06-03-2019 -------------------------------------------------------------------------------------------------------------------------------------
TEACHERS’ PERCEPTIONS ON THE USE OF GAMES IN THE POLYTECHNIC TEACHING CURRICULUM

In recent years, the adoption of games in the field of education has become extensive and prevalent. Its multi benefits and advantages are vastly spoken for, evidenced from the researches and papers conducted by the educational academia. There is increased support from the Singapore Government, both infrastructure and monetary funding, to support the adoption of games in education and learning. Increasingly, local educational institutes are reviewing their course curriculums to examine how the adoption of games can complement their current teaching pedagogies and in doing so, add value to the students’ learning experience. However, it is observed that the adoption of games in the teaching curriculum is low with few success stories being shared or publicised. With this in mind, an investigation was conducted with two groups of teachers from Ngee Ann Polytechnic (NP) to find out the factors that would influence the adoption of games as a learning strategy. A quantitative research was undertaken through the use of survey to investigate the teachers’ perceptions on the adoption of games as a learning strategy and the accompanying factors that influence these perceptions. The resultant statistical and corelational analysis of the research yielded inferences on the perceptions of teachers that is consistent with researches conducted overseas. Teachers are found to be aware of the potential of using games in the teaching curriculum and know that they should adopt it as part of their learning strategy. The teachers also identified key barriers against them doing so, namely time for development and implementation, as well as the lack of knowledge and resources. The result of the research also hints that teachers with gaming experiences are generally more likely to adopt games in their teaching but as they gained more teaching experiences, the likelihood of them doing so gets less. With the analysed research data, this paper proposes an established approach for designing games and an outline for the implementation of games in the classroom. In doing so, it is with hope that more teachers will adopt the use of games in their teaching curriculum.
Netnography: Origins, Foundations, Evolution and Axiological and Methodological Developments and Trends

Netnography originated in ethnography and evolved following the advances in data transmission technology. The netnographic method is distinguished by its axiological orientation residing in recognition of online social experiences. The main method for data collection adopted by the netnographer is participant observation. One premise that must be observed is the necessary estrangement, which means that the researcher must be a layman as regards the object of study. In the field of administration, netnography emphasized the area of marketing and consumer behavior. The goal is to understand the consumer culture of online communities. One of its main challenges consists of how to conduct ethical research. The current article reviewed the available literature about the netnography method, bringing a brief explanation about its emergence and evolution, as well as its characteristics and application. The article also presents the advantages, challenges, and trends of this modern research method and also suggests topics for future research.
Governance and Financial Performance in Family Business Groups: The Case of Mexico

We analyze the performance of companies in large Mexican family-based groups. Performance is influenced by the social connections (family relations) between the managers of the related companies and the CEO of the parent firm. Our purpose is to understand the decision behind having and keeping family members as division managers by analyzing the relationships between social connections and performance of the divisions. We use data from 15 family-based business groups that own 44 companies which in turn are traded on the Mexican Stock Exchange (BVM) during the period 1996-2011. The 487 observations are used to test four hypotheses concerning performance of family-managed vs. outsider-managed divisions, as well as the generation of the family managers, tenure, company size and age, and several control variables. We also show that family-based groups and conglomerates outperform independent firms on the Mexican stock exchange. We find that divisions led by founders have superior performance to those led by outside managers, who in turn outperform other family members such as sons and grandsons. Founders tend to have the longest tenure in the firms, followed by family members by generation, and finally outsiders. Our results support the nepotism view of family business management, in which relatives are preferred over outside managers, despite generally worse performance by the family-managed divisions. v2: We analyze performance of companies in large Mexican family-based groups.

Stability and Stabilization of Nonlinear Input-Delay Descriptor Systems

This work presents sufficient conditions for stability analysis and fuzzy controller synthesis for nonlinear descriptor systems represented by TS fuzzy models subject to input delay. The adopted control strategy consists in the so-called Parallel Distributed Compensation (PDC) and uses state-feedback to achieve system stabilization in the sense of Lyapunov. The methodology starts from the proposition of new Lyapunov-Krasovskii functionals together with the addition of free-weighting matrices and the use of a different majorant for the integral terms to reduce the conservatism. The conditions are formulated in terms of Linear Matrices Inequalities (LMI) taking into consideration membership functions assynchronisms of the closed-loop system. The obtained conditions are applied to nonlinear descriptor systems presented in current literature, proving their effectiveness and applicability.
A Smart Travel Companion Application with Location Base Scheduling

In urban life style traveling inside and outside of the city takes a major role. Because cities have, high density of population and high density of vehicles, and this will lead to the problem of city traffic and scheduling. This problem will cause big interruptions to working class citizens and undergraduates like being late to work, missing appointments, and missing lectures. To solve this, past few year’s companies like Google introduced navigation systems with predicted traffic. Still people does not often use these resources to improve their lifestyle. With the help of the google Maps, “ROADIE” is focused on filling the gap between the user and the information through an intelligent voice assistant by learning and analyzing users’ habits and introducing the integration of Navigation with Location base scheduling. Users can schedule appointments considering traffic conditions and receive feedback through text or voice base about the reachability of the destination. Users can plan their day according to the travel schedule and increase the productivity. In addition, users can contribute by posting traffic updates that system will analyze and send to the community to optimize existing predictions. The research team believes that the proposed application will contribute to solve the scheduling and traffic problems that faced by urban working class citizen.
Directors from Related Industries and Management Forecast Properties: An International Study

Managers cite information uncertainty as a partial explanation for their reluctance to voluntarily issue forecasts. Using an international sample of firms, we investigate whether directors with experience in a firm’s customer or supply industry (directors from related industries (DRI)) reduce this information gap, and in turn, improve management forecast properties. The issue is timely as world-wide heightened concern over a variety of risks is putting a premium on DRIs. We find that firms with DRIs are more likely to issue forecasts. Moreover, if firms do issue forecasts, those firms with DRIs issue more frequent forecasts than those issued by other firms. We also find some evidence that firms issue more precise forecasts if they have DRIs. The positive effect of DRIs on forecast issuance and frequency is most pronounced for firms in high information uncertainty environments, as captured by low firm-level analysts’ following and low country-level stock market information production. Our results hold in both U.S. and non U.S. sample firms, even after controlling for numerous determinants of management forecast properties. Further, influential DRIs have a more positive effect on management forecast issuance and frequency. Finally, we provide evidence that the stock market recognizes the crucial role that DRIs play in management forecasting: absolute value of cumulative announcement return around each management forecast is greater for firms with DRIs. Overall, our results suggest that DRIs play an important beneficial, but understudied, role in corporate disclosures.
On the stability of a heated rotating-disk boundary layer in a temperature-dependent viscosity fluid

The paper presents a linear stability analysis of the temperature-dependent boundary-layer flow over a rotating disk. Gas- and liquid-type responses of the viscosity to temperature are considered, and the disk rotates in both a quiescent and an incident axial flow. Temperature-dependent-viscosity flows are typically found to be less stable than the temperature independent cases, with temperature dependences that produce high wall viscosities yielding the least stable flows. Conversely, increasing the incident axial flow strength produces greater flow stability. Transitional Reynolds numbers for these flows are then approximated through an eN-type analysis and are found to vary in approximate concordance with the critical Reynolds number. Examination of the component energy contributions shows that flow stability is affected exclusively through changes to the mean flow. The results are discussed in the context of chemical vapor deposition reactors.
