The aim of this work is to create a guide for the selection and planning of an agri-photovoltaic mounting system. The mounting systems available on the market were analyzed and those that can be used in agri-photovoltaics were selected. Since there are many mounting systems on the market and there are hardly any technical differences between them, four systems were selected and described in this work. The systems are those that almost every manufacturer offers in a modified form. Three of the four systems are produced by the same manufacturer "ZIMMERMANN PV-Stahlbau GmbH & Co. KG", while the remaining system is produced by the manufacturer "Next2Sun GmbH". Through this collected knowledge about mounting systems, it was possible to create a questionnaire, which was then sent to farmers. The online questionnaire was sent via e-mail to the desired target group throughout Austria. It was sent to as many farmers as possible in order to obtain a large database. The data resulting from the questionnaire made it possible to create a guideline to support technicians in the planning of new Agri-PV systems.

Sustainability in sports tourism has increased in recent years. Sustainability is a particular focus for diving tourism. This paper analyses the meaning of sustainability to German speaking diving tourists to draw conclusions for the development of tourism strategies. Based on a literature review on the importance of sustainability in diving tourism, an empirical study was designed to understand the importance of the topic within the target group. A total of 174 German-speaking diving tourists were surveyed using an online-questionnaire. The subjects were clustered regarding their sustainable behavior. It could be shown that there is a correlation between age as well as gender and sustainable behavior. A conjoint measurement showed that for diving tourists, ecological aspects are more important than the prize of a diving trip. The gained insights can contribute to establish new and more sustainable offers in diving tourism and thus developing this area of sports tourism more sustainably overall.

Purpose Journals are the essential tools of researchers, especially academicians, to present their scientific findings. So, choosing the right journal helps not only science development but also their academic promotion. The purpose of this study is to examine the factors that Iranian medical researchers consider when selecting scholarly journals in which to submit their work. Design/methodology/approach A self-administered online questionnaire was emailed in May 2021, with 101 responses received. The sample included all the faculty members with the role of “lecturer” in Iranian medical universities and who have 1–5 articles in the Scopus database as early-career Iranian medical researchers. The questionnaire consisted of 36 items, divided into five sections: basic information, attitudes and beliefs, ways to choose a journal, problems and familiarity with the components of scientometrics/validity metrics related to journals. Findings The findings indicate that these researchers value the expertise of experienced researchers and professionals, like librarians, when selecting publication venues. They often use journal indexes to guide journal selection. They also consider factors like the length of typical peer review and the complexity of submission guidelines when making decisions. Research limitations/implications The study of one country, though detecting requirements of journal selection behavior, cannot be generalized to the entire region. Practical implications The current study has academic implications as far as decisions on journal selection are concerned. University policymakers in Iran may consider re-examining their emphasis on academicians’ promotion policies at Iranian universities of medical sciences. Originality/value These findings may support the work of early-career researchers and those individuals (e.g., librarians) that serve them, as well as publishers and editors of scholarly journals.

A Review of: Shenton, Andrew K. “The Information-Seeking Problems of English High Schoolers Responding to Academic Information Need.” Library Review 57.4 (2008): 276-88. Objective – To investigate the information-seeking behaviour of high school students looking to meet school-related information needs. Design – Online questionnaire. Setting – A comprehensive, publically-funded high school in north-east England. Subjects – Seventy-seven high school students between the ages of 13 and 18 who responded to an online questionnaire that was distributed to the 900-1000 students enrolled at the institution. Methods – An invitation to participate in an online questionnaire was sent to all students at the high school in October, 2006, via e-mail. The total number of invitations sent was not indicated, although it is noted that current enrolment at the school is approximately 900-1000 students across years 9 to 13. In the e-mail, students were provided with a link to a questionnaire posted on the school’s intranet. The questionnaire consisted of six multiple-choice and three open-ended questions. Qualitative data gathered through an open-ended question about problems encountered when seeking information for school was manually coded, and forms the focus of this article. Main Results – Seventy-seven online questionnaires were completed by students between 31 October and 27 November 2006, when analysis of the data began. Of the 77 respondents, only 35 provided data on problems encountered when seeking information for their assignments. Most of the respondents in this group were in years nine, ten and eleven (ages 13-16), with only two in year 12 (16-17) and four in year 13 (17-18). Over half (19/35) of respondents were female. Forty remaining respondents either stated that they experienced no problems in finding the information they needed for school or did not answer the relevant question on the questionnaire. Two participants indicated that they did not have the information they needed to complete their schoolwork because they did not look for it. Over 20 distinct information-seeking problems were identified through inductive analysis of the qualitative data provided by 35 participants. Difficulties encountered in the search for information largely fell into four major categories: problems determining an appropriate search strategy; barriers posed by limited school resources or Internet filtering software; “process frustrations” (280) stemming from the perceived inadequacies of search engines, poorly designed Web sites, and missing or broken Web links; and, “shortcomings in the retrieved information” (281) in terms of relevance and accuracy. In addition, a small number of students either indicated that they had difficulty applying the information they found to the problem that prompted the search, or were concerned about copyright restrictions on how they could use the information. All but two of the problems reported by students related to information-seeking on the Web. The Web was the most popular source of information for students, with 71 out of 77 respondents listing it as one of the sources or the only source they consulted for school. Conclusion – The results suggest a need for information literacy instruction among high school students, with a particular focus on effective use of the Web. The author suggests that some of the students’ frustrations may have been due to an “over-reliance” on Web resources, and could have been avoided if they were educated in the use of additional types of tools (286). This reliance on Web search engines proved problematic when Web filters impeded the students’ academic research. Some of the problems reported by students in 2006 in the search for academic information were similar to those recounted by students in 1999-2000 for the author’s earlier fieldwork in the same geographic area, including concerns about the accuracy or lack of detail of some Web sources, difficulties identifying effective search terms, and barriers posed by Internet filters. Additional research is needed to determine whether students experience the same difficulties when searching for information to meet personal needs and interests as they do when they are searching for information at the behest of a teacher.

ObjectivesDuring their lifetimes, a majority of musicians experience playing-related musculoskeletal disorders (PRMD). PRMD prevalence is tied to instrument choice, yet most studies examine heterogeneous groups of musicians, leaving some high-risk groups such as oboists understudied. This paper aims to (1) ascertain the prevalence and nature of PRMDs in oboists, (2) determine relevant risk factors, and (3) evaluate the efficacy of treatment methods in preventing and remedying injuries in oboe players.MethodsA 10-question online questionnaire on PRMDs and their treatments was completed by 223 oboists. PRMDs were compared across gender, weekly playing hours, career level, age, and years of playing experience.ResultsOf all respondents, 74.9% (167/223) reported having had at least one PRMD in their lifetime. A majority of these injuries (61.9% of all respondents) were of moderate to extreme severity (5 or higher on a scale of 1 to 10). Females (mean = 5.88) reported significantly more severe injuries than males. No significant effects of career level (i.e., professional vs. student vs. amateur), age, or years of playing experience were observed. We found significant non-linear relationships between weekly playing hours and PRMD prevalence and severity. Injuries were most commonly on the right side of the body, with the right thumb, wrist, hand, and forearm being most affected in frequency and severity. Of those injuries for which recovery information was provided, only 26.1% of injuries were “completely recovered.” The perceived effectiveness of a few treatments (physical therapy, rest, stretching, occupational therapy, massage) tended to be ranked more highly than others.ConclusionThe oboists in this study experienced high rates of PRMD, particularly in the right upper extremities. Females and those playing 7-9 and 16-18 h per week reported a significantly higher severity of injuries than other groups.

Companies’ ability to learn from projects is a source of competitive advantage in project-based industries. Learning from experiences in international markets is particularly important for global contractors so that the right bidding strategy can be developed, effective project governance systems can be established, and similar mistakes are not repeated. In this study, we assert that countries can be clustered according to their similarity so that experiences gained in these markets can be transferred and adapted to forthcoming projects. Thus, similarity factors to be used for clustering of countries can be identified, and a methodology can be developed to store, retrieve and reuse country-related information in international construction projects. In this paper, we report the factors identified for similarity assessment of countries to be used to facilitate learning from projects. As a result of literature review, interviews with experts and an online questionnaire administered to company professionals who have international construction experience, 12 factors have been identified for clustering of countries. As a result of ranking analysis; factors of “development level of and culture in the construction industry”, “political condition of the country” and “financial condition of the country” are obtained as the most important factors. The identified factors will be explained and how the clustering of countries can help companies to extract valuable information from previous experiences will be discussed.

The aim of this paper is to present research findings on prevalence and characteristics of cyberstalking in Serbia. A web-based questionnaire was used to collect data from a group of respondents who were recruited by snowball sampling via e-mail. A total of 237 respondents completed the online questionnaire. The aim of the first part of this paper is to determine the notion of cyberstalking as well as, to review research about the prevalence and the nature of stalking. The main results are the following: 39,6 % of respondents reported stalking; every fourth stalking victim is a victims of cyberstalking; mostly, cyberstalking victims were female and perpetrators were male. Victims were stalked by: persistent sending of unwanted e-mails and telephone calls, spreading rumors, abusive and negative comments and threats, encouraged other users to harass, threaten or insult, manipulating with victim's personal data, sending malicious programs and files, etc. In Serbia, cyberstalking is not criminalized yet and there are no organizations to whom victims may appeal and ask for help. We are hoping that this research will raise the awareness on cyberstalking and serve as a base for further research and legal reforms regarding cyberstalking victimization in Serbia.

Introduction: In many circumstances, especially in the Covid-19 period, it could be necessary to measure the QT interval repeatedly even daily. Hypothesis: The aim of the study was to evaluate the feasibility of remote measuring LI-LII and V2 leads with using a commercially available Apple Watch Series 4. Methods: The accuracy of the QTc calculation with the smartwatch compared to the standard ECG was tested using di!erent formulae. One hundred patients admitted to our CCU were studied. LI-LII and V2 tracings were obtained immediately after the recording of the standard 12-lead ECG. The LI was recorded with the smartwatch on the left wrist and the right index finger on the crown; LII was obtained with the watch on the left lower abdomen and the right index finger on the crown; V2 lead was recorded with a smartwatch in the fourth intercostal space left parasternal with the right index finger on the crown. All recorded 30” ECGs were digitally stored using the health application of an iPhone Series 10 in the pdf format. The advantage of saving the ECG in pdf format is that it can be sent also via e-mail. Results: There was an agreement between the QTLI, QT-LII, QT-V2 and QT mean intervals of smartphone electrocardiography tracings and standard electrocardiography using Spearman’s correlation coefficient of 0.881; 0.885; 0.801; 0.911 respectively [p<0.001]. The reliability of the mean QTc measurements was tested with Bland-Altman analysis using Bazett’s, Friedericia’s, and Framingham’s formulas between standard ECG and smartwatch(Figure). Conclusions: These data demonstrated the feasibility to measure the QTc in LI, LII and V2 leads with a smartwatch with results comparable to that performed with the standard ECG. These data could have an important clinical impact both for the widespread di!usion of smartwatches and for the monitoring of drug-induced QT interval prolongation, especially in the Covid-19 era.

If you had met Jon Postel in 1998, you might have been surprised to learn that you were in the presence of one of the Internet’s greatest living authorities. He had a rambling, ragged look, living in sandals and a large, unkempt beard. He lived like a modern-day Obi-Wan Kenobi, an academic hermit who favored solitary walks on the Southern California beach. When told once by a reporter that readers were interested in learning more about his personal life, he answered: “If we tell them, they won’t be interested anymore.” Yet this man was, and had been for as long as anyone could remember, the ultimate authority for assignment of the all-important Internet Protocol (IP) numbers that are the essential feature of Internet membership. Like the medallions assigned to New York City taxicabs, each globally unique number identifies a computer on the Net, determining who belongs and who doesn’t. “If the Net does have a God,” wrote the Economist in 1997, “he is probably Jon Postel.” Jon Postel was a quiet man who kept strong opinions and sometimes acted in surprising ways. The day of January 28, 1998, provided the best example. On that day Postel wrote an e-mail to the human operators of eight of the twelve “name servers” around the globe. Name servers are the critical computers that are ultimately responsible for making sure that when you type a name like google.com you reach the right address (123.23.83.0). On that day Postel asked the eight operators, all personally loyal to Postel, to recognize his computer as the “root,” or, in essence, the master computer for the whole Internet. The operators complied, pointing their servers to Postel’s computer instead of the authoritative root controlled by the United States government. The order made the operators nervous—Paul Vixie, one of the eight, quietly arranged to have someone look after his kids in case he was arrested. Postel was playing with fire. His act could have divided the Internet’s critical naming system into two gigantic networks, one headed by himself, the other headed by the United States. He engineered things so that the Internet continued to run smoothly. But had he wanted to during this critical time, he might have created chaos.

Purpose The purpose of this paper is to examine the continuing professional development (CPD) activities undertaken by special librarians in Jamaica, their motivation, the challenges faced and the areas of interest for professional development. Design/methodology/approach Special librarians working in Jamaica were surveyed using an online questionnaire which was disseminated via e-mail. Findings The study indicates that special librarians in Jamaica were engaged in both formal and informal CPD activities. They were motivated by factors such as keeping up to date with changes in librarianship and personal satisfaction. Challenges to participating in CPD include, lack of funding, time constraints and lack of worthwhile options. Areas of interest for CPD were mainly information technology-based. Research limitations/implications The study was limited to the contact lists of the special libraries section of the Library and Information Association of Jamaica (LIAJA) and the Government Library and Information Network of the Jamaica Library and Information Network (JAMLIN). Practical implications The results have implications for the planning and implementation of continuing professional activities for Jamaica’s special librarians. It also fills a gap in library literature regarding the continuing professional activities of special librarians. Originality/value The paper is one of few studies focusing on the CPD activities of special librarians undertaken in a developing country.

This chapter considers the theme of trespass in cyberspace. In order to prevent unauthorized use of their data several U.S. companies have hastily filed lawsuits alleging trespass to chattels. But some of this data usage, especially for metasites, is socially valuable. Nonetheless, the courts are generally sympathetic with these trespass claims even if this means that activities like spidering or e-mail are constrained in certain contexts. Legal scholars have criticized this trend because it creates a novel property right in factual data which is not eligible for copyright protection. These legal concerns are justified, but what should moralists be saying about this matter? We argue here that both eastern and western philosophies recognize the need to respect the common good of a community or common venture. This awareness should temper a company’s narrow focus on proprietary property rights. We attempt to define the Net’s common good (or commonly shared values) and make the case that Internet users have a prima facie duty to support that common good. Thus, prudent and morally responsible companies operating on the Net will seek to balance their property entitlements with this affirmative duty to support the Internet’s common good. There is no magic formula for achieving this precarious balance, but we offer some general criteria that will orient managers toward the right direction. Finally, we explain that a private settlement of trespass matters is clearly welfare-enhancing.
