Police work and new 'security devices' : a tale from the beat

Mobile technologies have brought about major changes in police equipment and police work. If a utopian narrative remains strongly linked to the adoption of new technologies, often formulated as 'magic bullets' to real occupational problems, there are important tensions between their 'imagined' outcomes and the (unexpected) effects that accompany their daily 'practical' use by police officers. This article offers an analysis of police officers' perceptions and interactions with security devices. In so doing, it develops a conceptual typology of strategies for coping with new technology inspired by Le Bourhis and Lascoumes: challenging, neutralizing and diverting. To that purpose, we adopt an ethnographic approach that focuses on the discourses, practices and actions of police officers in relation to three security devices: the mobile digital terminal, the mobile phone and the body camera. Based on a case study of a North American municipal police department, the article addresses how these technological devices are perceived and experienced by police officers on the beat.

Digital Audio Broadcasting: Technology and Prospects

The subject of the thesis was the digital audio broadcasting technology developed in the Eureka project 147. The research was based on the literature on the subject. At first, some reasons for the digitisation of broadcasting technology were given. Next, the channel multiplexing and channel coding methods employed by digital radio were discussed. The design of these methods is based on certain phenomena related to the propagation of radio-frequency signals, and these phenomena were also described. After that, audio and data transfer mechanisms as well as the structure of digital radio network were explained. Furthermore, digital audio and data services were considered. Finally, the digital radio was examined from marketing and administrative aspects. From a merely technical point of view, the digital radio technology offers several improvements in comparison with analogue technology. However, the digital radio has not become as widespread as it was perhaps originally expected during its development.

Implementation and Integration of New Baggage Logistic Centre at HelsinkiVantaa Airport

This thesis deals with improving international airport baggage supply chain management (SCM) by means of information technology and new baggage handling system. This study aims to focus on supply chain visibility in practice and to suggest different ways to improve the supply chain performance through information sharing. The objective is also to define how radio frequency identification (RFID) and enterprise resource planning (ERP) can make processes more transparent. In order to get full benefits from processes, effective business process management and monitoring as well as the key performance indicators must be defined, implemented and visualized through e.g. dashboard views for different roles. As an outcome of the research the need for the use of information technology systems and more advanced technologies, e.g. RFID in the supply chain management is evident. Sophisticated ERP is crucial in boosting SCM business processes and profitability. This would be beneficial for dynamic decision making as well in the airport and airline supply chain management. In the long term, economic aspects support the actions I have suggested in order to make production more flexible in reacting to quick changes.

La Salut als diaris digitals, una qüestió de salut digital: les notícies de salut en els diaris digitals en llengua catalana: exploració i assaig metodològic per a l'anàlisi descriptiva

En l’actual context de la societat de la informació, les noves tecnologies de la comunicació i, específicament, el fenomen d’Internet, adquireixen una importància rellevant en tots els sectors socials i fan replantejar la comunicació de masses. Les característiques que ofereixen els mitjans digitals (multimedialitat, hipertextualitat, interactivitat) comporten una nova forma d’estructurar i llegir la informació. Així, capçaleres i periodistes s’han d’actualitzar en la producció de la informació i en la seva transmissió, i l’usuari ha d’aprendre noves formes de lectura per adaptar-se al nou paradigma comunicacional. D’altra banda, la societat del benestar en què vivim reclama cada cop més als mitjans de comunicació generals i també específicament als digitals que parlin de temes de salut. Aquests mitjans esdevenen fonts principals d’aquest tipus d’informació, després del metge, per a la gestió autònoma de la pròpia salut. És a partir d’aquesta convergència de mitjans digitals, periodisme i salut, de la necessitat d’explorar la situació actual i del desig d’aportar coneixements per a la millora de la pràctica professional del periodisme, que es desenvolupa el treball que es presenta en aquesta memòria. El projecte que es presenta és una anàlisi restrospectiva i descriptiva de les notícies de salut que es produeixen durant un mes als diaris digitals que publiquen en llengua catalana: El Periódico de Catalunya, l’Avui, i LaMalla.net.

The relationship between a virtual leader’s communication practices and a virtual team’s performance

A lot of research has been carried out into virtual teams and virtual leadership, yet there is hardly any research available on the communication behaviour of virtual leaders within a real business context. This research assessed the communication practices of virtual leaders and analysed the relationship between these practices and the performance of virtual teams. The objective of this research was to examine the distinctions of virtual teams, to study the leader’s role in a virtual team and its performance, and to examine the leader’s communication practices within virtual teams. The research involves a case study in which interviews have been carried out within an international technology company headquartered in Finland. Qualitative research methods were applied in the research. Based on the results of the study it can be said that there is a strong relationship between a virtual leader’s communication practices and a virtual team member’s job satisfaction. Through their communication practices, activities and message contents, leaders can affect the job satisfaction of virtual team members. In virtual leadership the focus is not in virtual but in leadership. It does not matter if the context is virtual or face-to-face; similar communication practices are good in both cases. As the global economic crisis strongly affected the sales results of the between a leader’s communication practices and a virtual team’s objective performance cannot be made.

“THE PATIENT SURVIVED DESPITE THE TREATMENT”. A study of Finnish health policy and New Public Management. Case: The Government Resolution on the Health 2015 public health programme.

Internationally, Finland has been among the most respected countries during several decades in terms of public health. WHO has had the most significant influence on Finnish health policy and the relationship has traditionally been warm. However, the situation has slightly changed in the last 10-20 years. The objectives of Finnish national health policy have been to secure the best possible health for the population and to minimize disparities in health between different population groups. Nevertheless, although the state of public health and welfare has steadily improved, the socioeconomic disparities in health have increased. This qualitative case study will demonstrate why health is political and why health matters. It will also present some recommendations for research topics and administrative reforms. It will be argued that lack of political interest in health policy leads to absence of health policy visions and political commitment, which can be disastrous for public health. This study will investigate how Finnish health policy is defined and organised, and it will also shed light on Finnish health policy formation processes and actors. Health policy is understood as a broader societal construct covering the domains of different ministries, not just Ministry of Social Affairs and Health (MSAH). The influences of economic recession of the 1990s, state subsidy reform in 1993, globalisation and the European Union will be addressed, as well. There is not much earlier Finnish research done on health policy from political science viewpoint. Therefore, this study is interdisciplinary and combines political science with administrative science, contemporary history and health policy research with a hint of epidemiology. As a method, literature review, semi-structured interviews and policy analysi will be utilised. Institutionalism, policy transfer, and corporatism are understood as the theoretical framework. According to the study, there are two health policies in Finland: the official health policy and health policy generated by industry, media and various interest organisations. The complex relationships between the Government and municipalities, and on the other hand, the MSAH and National Institute for Health and Welfare (THL) seemed significant in terms of Finnish health policy coordination. The study also showed that the Investigated case, Health 2015, does not fulfil all necessary criteria for a successful public health programme. There were also several features both in Health 2015 and Finnish health policy, which can be interpreted in NPM framework and seen having NPM influences.

Sosiaalinen media markkinointiviestinnän välineenä presidentinvaalikampanjassa

Vuoden 2012 presidentinvaalit veivät sosiaalisen median käytön politiikassa aivan uudelle tasolle. Tässä tutkimuksessa kohteena onkin Vihreän Liiton ehdokkaan Pekka Haaviston vaalikampanja, joka painottui vahvasti sosiaalisen median ympäristöön. Empirian tarkoituksena on ymmärtää, miten sosiaalista mediaa hyödyntämällä Haavisto onnistuttiin nostamaan altavastaajan roolista toiseksi potentiaaliseksi presidenttiehdokkaaksi Sauli Niinistön kanssa. Empiirisen tutkimuksen tueksi käydään tutkimuksessa ensin läpi aihetta syvemmin valottavia teorioita ja aiemmin tehtyjä tutkimuksia markkinointiviestinnän, markkinointiviestintäkampanjan sekä sosiaalisen median alueilta.

Katsaus lisäävän valmistuksen (aka 3D-tulostus) mahdollisuuksiin ja kustannuksiin metallisten tuotteiden valmistuksessa: Case jauhepetitekniikka

Suurelle yleisölle lisäävä valmistustekniikka eli ns. 3D-tulostustekniikka näyttäytyy lehtien otsikoissa ja artikkeleissa esiin pulpahtavana ”muotiaiheena”, mutta sekä muovien 3D-tulostustekniikka että metallienkin vastaava valmistustekniikka on ollut olemassa maailmalla ja Suomessa 80-luvun puolivälistä alkaen. Yhdysvalloissa ja Saksassa tekniikkaa käytetään valmistavassa teollisuudessa toiminnallisten osien tuotannossa. Esimerkiksi lentokoneen suihkumoottorien osia ja lääketieteellisiä välineitä tehdään metallijauheesta lisäävän valmistuksen avulla. Itse asiassa eräs menetelmä metalliesineiden valmistamiseksi lasersäteen avulla keksittiin Suomessa ja sitä myös kehiteltiin täällä, mutta teollisuudenala lähti aikanaan nousuun Saksassa. Lisäävä valmistus on tällä hetkellä maailmanlaajuisesti eräs kiinnostavista tuotantotekniikoista, jonka uskotaan muuttavan monia asioita tuotteiden suunnittelussa, toiminnoissa ja valmistuksessa. Tämä tekniikka ei kiinnosta pelkästään valmistavaa teollisuutta, vaan tietotekniikan, lääketieteen, koruvalmistuksen ja muotoilun osaajat sekä uusien liiketoimintamallien kehittäjät ja logistiikka operaattorit ovat teknologiasta kiinnostuneita. Suomelle 3D-tulostustekniikka on suuri mahdollisuus, sillä maassamme on vahva teollinen tieto- ja viestintätekniikkaosaaminen sekä lisäksi olemme maassamme erikoistuneet varsin vaativien teollisiin laitteiden valmistukseen. Eräät suurimmista mahdollisuuksista tällä tekniikalla ovat toimitusketjuihin liittyvät muutokset. Uutta on, että pienetkin yritykset ja organisaatiot voivat soveltaa tätä tekniikkaa valmistuksessa ja jopa kehitellä täysin uusia tuotteita. On myös arvioitu, että lisäävän valmistuksen merkitys valmistustapoihin ja toimitusketjuihin voi olla suurempi kuin koskaan aikaisemmin minkään teknologisen uudistuksen kohdalla. Lisäävästä valmistuksesta usein puhutaankin kolmantena teollisena vallankumouksena juuri tämän takia. 3D-tulostuksen kustannuksia tarkasteltaessa on tärkeätä huomata että vain sulatetun jauheen määrä ratkaisee, ei käytettävän geometrian monimutkaisuus. Tämä erottaa perinteisen ja lisäävän valmistuksen toisistaan. Perinteisesti kappaleen keventäminen on maksanut ”ylimääräistä”, kun taas lisäävässä valmistuksessa kappaleen keveys on jopa kustannusta alentava tekijä. Valmistettavan kappaleen korkeus on yksi kriittisimpiä kustannuksiin vaikuttavia tekijöitä. Tämän vuoksi useamman kappaleen valmistus yhdellä kertaa parantaa kannattavuutta huomattavasti. Samalla kertaa voi ja itse asiassa kannattaakin valmistaa keskenään erilaisia kappaleita. Perinteiset valmistustavat sen sijaan ovat nykyajan vaatimuksille liian hitaita; ne joustavat huonosti, kun kyseessä on pienet, asiakaslähtöiset erät. Trendi on globaalisti kohden yksilöllisiä asiakaslähtöisiä tuotteita, jolloin myös valmistustekniikoiden on oltava joustavia pysyäkseen näiden vaatimusten perässä. Lisäävä valmistus sopii erityisesti hyvin piensarjatuotantoon. Suuremmissa valmistuserissä kuitenkin perinteiset tekniikat ovat kustannustehokkaampia.

Between Memory and Strategy: Media Discourse Analysis of an Industrial Shutdown

In 2006 UPM was able to gain a level of social legitimacy that allowed it to carry out one of the largest industrial restructuring programmes in Finnish industrial history, shut down major operations in Finland and still appear to be functioning in the interests of the nation as well as itself. This study considers and examines various contexts of this shutdown with the aim of demonstrating how profoundly mediated such organizational events are though they appear to be produced primarily through strategic company decisions. The study aims to examine the processes of mediation at two levels. At one level, through close analysis of press releases and newspaper reports in local and national newspapers, the study presents a discursive analysis of the Voikkaa case. The discursive analysis focuses on providing historical contexts for understanding why this organizational event was also an occasion for reimagining the past and future of the Finnish nation; spatial contexts for understanding the differing struggles over the meaning of the event nationally and regionally; and the temporal dynamics of the media reports. At another level, the study considers and refines methods for reading and analyzing mediation in organization studies. Bringing together recent research of media text–based legitimation studies, emerging research on organizational memory and organizational death and a Foucaultian analytics of power, this work suggests that organizational research needs to be less concerned with particular typologies and narratives of shutdowns, and more curious about the processes of mediation through which organizational events are imagined and remembered.

Production and partial characterization of lipase from Penicillium verrucosum obtained by submerged fermentation of conventional and industrial media

The growing interest in lipase production is related to the potential biotechnological applications that these enzymes present. Current studies on lipase production by submerged fermentation involve the use of agro-industrial residues aiming at increasing economic attractiveness. Based on these aspects, the objective of this work was to investigate lipase production by Penicillium verrucosum in submerged fermentation using a conventional medium based on peptone, yeast extract, NaCl and olive oil, and an industrial medium based on corn steep liquor, Prodex Lac (yeast hydrolysate), NaCl and olive oil, as well as to characterize the crude enzymatic extracts obtained. Kinetics of lipase production was evaluated and the highest enzymatic activities, of 3.15 and 2.22 U.mL-1, were observed when conventional and industrial media were used, respectively. The enzymatic extract showed optimal activity in the range from 30 to 40 °C and at pH 7.0. Although the industrial medium presents economical advantages over the conventional medium, the presence of agro-industrial residues rich in nitrogen and other important nutrients seemed to contribute to a reduction in lipase activity.

Conceptual Analysis of Web 2.0 Technology Use to Enhance Parent–School Relationships

Parent–school relationships contribute significantly to the quality of students’ education. The Internet, in turn, has started to influence individuals’ way social communication and most school boards in Ontario now use the Internet to communicate with parents, which helps build parent–school relationships. This project comprised a conceptual analysis of how the Internet enhances parent–school relationships to support Ontario school board administrators seeking to implement such technology. The study’s literature review identified the links between Web 2.0 technology, parent–school relationships, and effective parent engagement. A conceptual framework of the features of Web 2.0 tools that promote social interaction was developed and used to analyze websites of three Ontario school boards. The analysis revealed that school board websites used static features such as email, newsletters, and announcements for communication and did not provide access to parents for providing feedback through Web 2.0 features such as instant messaging. General recommendations were made so that school board administrators have the opportunity to implement changes in their school community with feasible modifications. Overall, Web 2.0-based technologies such as interactive communication tools and social media hold the most promise for enhancing parent–school relationships because they can help not only overcome barriers of time and distance, but also improve the parents’ desire to be engaged in children’s education experiences.

Some Studies and New Results on Multi Microprocessor Applications

One of the fastest expanding areas of computer exploitation is in embedded systems, whose prime function is not that of computing, but which nevertheless require information processing in order to carry out their prime function. Advances in hardware technology have made multi microprocessor systems a viable alternative to uniprocessor systems in many embedded application areas. This thesis reports the results of investigations carried out on multi microprocessors oriented towards embedded applications, with a view to enhancing throughput and reliability. An ideal controller for multiprocessor operation is developed which would smoothen sharing of routines and enable more powerful and efficient code I data interchange. Results of performance evaluation are appended.A typical application scenario is presented, which calls for classifying tasks based on characteristic features that were identified. The different classes are introduced along with a partitioned storage scheme. Theoretical analysis is also given. A review of schemes available for reducing disc access time is carried out and a new scheme presented. This is found to speed up data base transactions in embedded systems. The significance of software maintenance and adaptation in such applications is highlighted. A novel scheme of prov1d1ng a maintenance folio to system firmware is presented, alongwith experimental results. Processing reliability can be enhanced if facility exists to check if a particular instruction in a stream is appropriate. Likelihood of occurrence of a particular instruction would be more prudent if number of instructions in the set is less. A new organisation is derived to form the basement for further work. Some early results that would help steer the course of the work are presented.

A study of the information seeking bebavior of science and technology teachers and researchers of Cocbin University of Science and Technology and University of Kerala in the cbanged library environment

Information communication technology (IC T) has invariably brought about fundamental changes in the way in which libraries gather. preserve and disseminate information. The study was carried out with an aim to estimate and compare the information seeking behaviour (ISB) of the academics of two prominent universities of Kerala in the context of advancements achieved through ICT. The study was motivated by the fast changing scenario of libraries with the proliferation of many high tech products and services. The main purpose of the study was to identify the chief source of information of the academics, and also to examine academics preference upon the form and format of information source. The study also tries to estimate the adequacy of the resources and services currently provided by the libraries.The questionnaire was the central instrument for data collection. An almost census method was adopted for data collection engaging various methods and tools for eliciting data.The total population of the study was 957, out of which questionnaire was distributed to 859 academics. 646 academics responded to the survey, of which 564 of them were sound responses. Data was coded and analysed using Statistical Package for Social Sciences (SPSS) software and also with the help of Microsofl Excel package. Various statistical techniques were engaged to analyse data. A paradigm shift is evident by the fact that academies push themselves towards information in internet i.e. they prefer electronic source to traditional source and the very shift is coupled itself with e-seeking of information. The study reveals that ISB of the academics is influenced priman'ly by personal factors and comparative analysis shows that the ISB ofthc academics is similar in both universities. The productivity of the academics was tested to dig up any relation with respect to their ISB, and it is found that productivity of the academics is extensively related with their ISB. Study also reveals that the users ofthe library are satisfied with the services provided but not with the sources and in conjunction, study also recommends ways and means to improve the existing library system.

Movimientos sociales su construcción narrativa desde los nuevos medios: los Indignados bogotanos en Twitter

Se analiza la relación entre movimientos sociales y nuevos medios en Colombia, preguntando en particular por las posibilidades narrativas que tienen los movimientos sociales en el nuevo espacio comunicativo abierto por internet. Para ello, se lleva a cabo un estudio descriptivo del relato elaborado en la red social Twitter por activistas virtuales del movimiento de indignación surgido en Bogotá tras la destitución del alcalde mayor, Gustavo Petro, a finales de 2013. Se encontró que Twitter fue un espacio esencialmente de disputa. El relato del movimiento fue construido en permanente contrapunteo no solo con las informaciones de los medios de comunicación tradicionales y las intervenciones de los líderes políticos, sino también con expresiones ciudadanas rivales, que se movilizaron paralelamente en la misma red social en un ejercicio de contestación. Esta investigación emplea como marco analítico la “autocomunicación de masas” propuesta por Manuel Castells.

Dietary prebiotics: current status and new definition

In November 2008, a group of scientists met at the 6th Meeting of the International Scientific Association of Probiotics and Prebiotics (ISAPP) in London, Ontario, Canada, to discuss the functionality of prebiotics. As a result of this, it was concluded that the prebiotic field is currently dominated by gastrointestinal events. However, in the future, it may be the case that other mixed microbial ecosystems may be modulated by a prebiotic approach, such as the oral cavity, skin and the urogenital tract. Therefore, a decision was taken to build upon the current prebiotic status and define a niche for ‘dietary prebiotics’. This review is co-authored by the working group of ISAPP scientists and sets the background for defining a dietary prebiotic as ‘‘a selectively fermented ingredient that results in specific changes in the composition and/or activity of the gastrointestinal microbiota, thus conferring benefit(s) upon host health’’.
