Terrorist Events

The frequency of terrorist events in Pakistan has increased considerably in the past several years. These events are frequent and not random, making it important to identify useful patterns in their occurrences to assist counterterrorism organizations. In this paper, we conducted such an analytical activity for the first time in Pakistan. We acquired data of terrorist events from reliable online sources and applied data preprocessing techniques followed by cluster analysis. Based on statistical correlation, we discovered clusters over the following combinations: (1) “Event of Terrorism—Target of Terrorism”; and (2) “Event of Terrorism—Method of Terrorism”. A more significant clustering is one which groups distinct combinations into separate clusters. We analyzed these clusters along three dimensions: (1) Annually for the time period 1988–2012; (2) for each Pakistani province; and (3) for different types of terrorist events. We also proposed a statistic for gauging the intensity of terrorism and analyzed it along the same three dimensions. Our results were extensive, but generally indicated significant Event–Target and Event–Method clusters, as well as increasing and decreasing trends in terrorism intensity. These can assist counterterrorism authorities in thwarting future attacks and arresting the responsible criminals.

Different Types

Purpose – The purpose of this paper is to identify different types of organizational innovativeness in Austrian hotels and analyze their connection to (innovation) success. In the face of growing international competition, innovation is becoming increasingly important for Austria’s hotel industry. A prerequisite for innovation is organizational innovativeness. Design/methodology/approach – This paper is based on a quantitative survey of 255 Austrian hotel businesses with a minimum of five employees. Innovativeness was measured by three dimensions (willingness, ability and possibility to innovate) and success by five dimensions (overall performance: financial, market and employee-related success; innovation success: product and process innovations). Findings were obtained by combining an exploratory factor analysis with a cluster analysis. Findings – Factor analysis reveals five factors determining organizational innovativeness: “cooperation as trigger for change”; “acceptance of change”; “resource based scope for change”; “pluralism as trigger for change”; and “loose coupling and error-tolerance”. The cluster analysis identifies four types of hotels regarding organizational innovativeness indicating differences regarding the success dimensions: “potential innovators hindered by scarce resources and unsupportive structures”, “well-resourced conservatives”, “potential innovators hindered by a haphazard approach” and “cautious idea hunters”. On the whole, results show that a balanced configuration of organizational innovativeness combined with a cautious approach is connected with greater (innovation) success. Research limitations/implications – Key-informant and survivor biases have to be considered as all items in the questionnaire were evaluated by self-assessment of the hotel management and only successful hotels (in the sense of survival) were analyzed. One important implication is that (innovation) success depends on the system that enables it; therefore, organizational innovativeness is a precondition of successful innovations. Nevertheless, there is little research on organizational innovativeness in the service sector so far. Practical implications – This paper supports tourism businesses in understanding the concept of organizational innovativeness and its relation to (innovation) success. SMEs, which dominate the Austrian hotel industry, tend to focus on the financial aspect of innovativeness and, in general, do not consider the range of factors that constitute an organization’s innovativeness (willingness, ability and possibility to innovate) and the various outcomes. Originality/value – By combining organizational innovativeness and (innovation) success, the paper applies an important element of innovation theory to the Austrian hotel industry. The characterization of different types of hotels regarding organizational innovativeness and success enables a (self-) assessment for hotel businesses and the deduction of customized implications.

AbstractBackground:China is ranked 42nd on the Global Terrorism Index (2019), a scoring system of terrorist activities. While China has a relatively low terrorism risk, events globally have wide-ranging repercussions for future attacks, putting first responders and emergency health workers at risk. This study aims to provide the epidemiological context for the past decade detailing the unique injury types responders are likely to encounter and to develop training programs utilizing these data.Methods:The Global Terrorism Database (GTD) was searched for all attacks in China between the years 2008-2018. Attacks met inclusion criteria if they fulfilled the terrorism-related criteria as set by the GTD’s Codebook. Ambiguous events, as defined by the GTD’s Codebook, were excluded. English language grey literature was searched to ensure no events meeting these criteria were missed. A focused search of online English language newspaper articles was also performed for any terrorist events between 2008-2018.Results:One-hundred and eight terrorist events occurred in the study time period. Of the 108 incidents, forty-seven (43.5%) involved Explosives/Bombs/Dynamite (E/B/D) only, with an average fatality count of 2.9 and injury count of 7.5 per event. Twenty-seven (25.0%) used bladed or blunt weapons in melees with an average fatality count of 9.7 and an injury count of 8.8 per event. Five (4.6%) involved incendiary weapons with an average fatality count of 2.4 and an injury count of 7.2 per event. Two used only chemical weapons (1.8%) with no recorded deaths and an injury count of 27.0 per event. Two events had unknown weapon types (1.8%) with one recorded death and no injury count. One event used a firearm (0.9%) and led to one death and no injuries. One event used a vehicle (0.9%), which also led to one death and no recorded injuries. Twenty-three attacks used a mix of weapons (21.2%) with an average fatality count of 17.1 and an injury count of 12.0 per event.Conclusions:One-hundred and eight terrorist attacks were recorded between 2008-2018 on Chinese soil using well-understood modalities. This resulted in a total of 809 recorded fatalities with 956 non-fatal injuries. The most commonly chosen methodology was E/B/D, followed by melees and the use of bladed weapons. Three events individually recorded a combined casualty toll of over 100 people.

AbstractThis paper critically evaluates how archaeologists define ‘grave goods’ in relation to the full spectrum of depositional contexts available to people in the past, including hoards, rivers and other ‘special’ deposits. Developing the argument that variations in artefact deposition over time and space can only be understood if different ‘types’ of find location are considered together holistically, we contend that it is also vital to look at the points where traditionally defined contexts of deposition become blurred into one another. In this paper, we investigate one particular such category – body-less object deposits at funerary sites – in later prehistoric Britain. This category of evidence has never previously been analysed collectively, let alone over the extended time period considered here. On the basis of a substantial body of evidence collected as part of a nationwide survey, we demonstrate that body-less object deposits were a significant component of funerary sites during later prehistory. Consequently, we go on to question whether human remains were actually always a necessary element of funerary deposits for prehistoric people, suggesting that the absence of human bone could be a positive attribute rather than simply a negative outcome of taphonomic processes. We also argue that modern, fixed depositional categories sometimes serve to mask a full understanding of the complex realities of past practice and ask whether it might be productive in some instances to move beyond interpretively confining terms such as ‘grave’, ‘hoard’ and ‘cenotaph’. Our research demonstrates that is it not only interesting in itself to scrutinize archaeological evidence that does not easily fit into traditional narratives, but that the process of doing so also sheds new light on the validity of our present-day categories, enabling deeper insights into how people in the past ordered their material and conceptual worlds. Whilst our main focus is later prehistoric Britain, the issues we consider are potentially relevant across all periods and regions.

Object. The purpose of this study was to evaluate the US neurosurgery workforce by reviewing journal recruitment advertisements published during the past 10 years. Methods. The number of available academic and private neurosurgical staff positions was determined based on recruitment advertisements in the Journal of Neurosurgery and Neurosurgery for the 10-year period from 1994 to 2003. Advertisements were evaluated for practice venue, subspecialization, and location. The numbers of active neurosurgeons and graduating residents also were reviewed. The number of advertised neurosurgical positions increased from 141.6 ± 38.2 per year from 1994 through 1998 to 282.4 ± 13.6 per year from 1999 through 2003 (mean ± standard deviation, p < 0.05). The mean number of academic positions increased from 50.6 ± 11.1 to 95 ± 17.5 (p <0.05), and the mean number of private positions rose from 91 ± 30.4 to 187.4 ± 6.8 (p <0.05). Subspecialty positions represented a mean of only 15.6 ± 5% per year during the first time period and 18.8 ± 3% per year in the second period (p = 0.22), and therefore the majority of positions advertised continued to be those for generalists. The number of practicing neurosurgeons declined after 1998, and by 2002 it was less than it had been in 1991. The numbers of incoming and matriculating residents during the study period were static. Conclusions. The number of recruitment advertisements for neurosurgeons during the last 5 years has increased significantly, concomitant with a severe decline in the number of active neurosurgeons and a static supply of residents.

AbstractThe influence of internal and external parasites on the health of Polish konik horses housed in different types of management strategies in Poland is discussed. This study includes consolidated data of different authors from the past 50 years, supplemented by results of more recent research. A total of 38 species of helminths (i.e., 37 Nematoda and one Cestoda) and five Diptera species were recorded from the horses. Protozoan parasites, Cryptosporidium spp. and Theileria equi, and the Rickettsiales, Anaplasma phagocytophilum, were observed for the first time in Poland.

In the past time, it was neglected that different types of the deformation have an important effect on the Load-Displacement (L-D) relationship in bolt slippage. In this paper, 3D finite element models with double bolt joints are established by the ANSYS finite element package and a series of bolt slippage tests are conducted. The large lateral deformation in the process of bolt slippage is put forward for the first time. Numerical and experimental results show that large lateral deformation makes the stiffness of bolt joint smaller.

Different Cell Types

Various types of intermediate-sized (10-nm) filaments have been found and described in many different cell types during the past few years. Despite the differences in the chemical composition among the different types of filaments, they all yield common structural features: they are usually up to several microns long and have a diameter of 7 to 10 nm; there is evidence that they are made of several 2 to 3.5 nm wide protofilaments which are helically wound around each other; the secondary structure of the polypeptides constituting the filaments is rich in ∞-helix. However a detailed description of their structural organization is lacking to date.

Research into the norm of internality ( Beauvois & Dubois, 1988 ) has shown that the expression of internal causal explanations is socially valued in social judgment. However, the value attributed to different types of internal explanations (e.g., efforts vs. traits) is far from homogeneous. This study used the Weiner (1979 ) tridimensional model to clarify the factors explaining the social utility attached to internal versus external explanations. Three dimensions were manipulated: locus of causality, controllability, and stability. Participants (N = 180 students) read the explanations expressed by appliants during a job interview. They then described the applicants on the French version of the revised causal dimension scale and rated their future professional success. Results indicated that internal-controllable explanations were the most valued. In addition, perceived internal and external control of explanations were significant predictors of judgments.

According to the latest forecasts, it will take 10 years for the world economy to get back to “decent shape”. Some more critical estimates suggest that the whole western world will have a “colossal mess” within the next 5–10 years. Regulators of some major countries significantly and over a short time‑period changed their forecasts for the worse which means that uncertainty in the outlook for the future persists. Indeed, the intensive anti‑crisis measures have reduced the severity of the past problems, however the problems themselves have not disappeared. Moreover, some of them have become more intense — the eurocrisis, excessive debts, global liquidity glut against the backdrop of its deficit in some of market segments. As was the case prior to the crisis, derivatives and high‑risk operations with “junk” bonds grow; budget problems — “fiscal cliff” in the US — and other problems worsen. All of the above forces the regulators to take unprecedented (in their scope and nature) steps. Will they be able to tackle the problems which emerge?

This paper discusses the need for nationally based analytical models of the medieval period. The use of cluster analysis as a method for classifying demesne farms, by the crops they grew and their livestock management, is explained. Successful implementation of cluster analysis requires both the existence of a large base sample, to permit isolation of specific groupings within the data, and access to considerable processing time. The paper concludes by demonstrating how discriminant analysis can provide an efficient and systematic way of classifying even a single manor within a national frame of reference.
