Tourism statistics and unobserved tourism: empirical evidences in Sicily

2013

Despite its strategic importance, accurately measuring visitor attendance has been a challenging and problematic exercise for tourism managers for decades. Consequently, the primary aim of tourism statistics of accurately quantify tourism flows has been only partially achieved; indeed at a lower territorial scale tourism statistics appear less precise and accurate. The aim of this paper is: to introduce the concept of unobserved tourism, by highlighting the main limits of official statistical systems (with a special focus on the European statistical system on tourism statistics; to formalize a theoretical model in which tourism nights and trips in a given destination are decomposed into obs…

A holistic perspective on the theoretical foundations for ICT4D research

2018

While many theories have guided research Information and Communication Technologies for Development (ICT4D), we are yet to construct a clear and coherent narrative that would help us answer the question of how ICT fosters development in underdeveloped communities. In this paper, we argue that one of the main reasons for this is that our holistic understanding of ICT4D is seldom grounded in theories to understand the core areas that define the field, namely, ICT, Development, and, ‘4’ which are the transformative processes that link the two. Through a brief literature review, we list theories that have informed ICT4D research in each of these areas. We present examples of theories, namely, C…

Emotional and behavioral difficulties in adolescence: Relationship with emotional well-being, affect, and academic performance

2018

Abstract The main purpose of this study was to examine difficulties in behavioral and emotional adjustment and their relationship to subjective well-being, positive and negative affect, and academic performance in a representative sample of nonclinical adolescents. The sample consisted of a total of 1,664 participants (M = 16.12 years, SD = 1.36, range 14-19 years), selected through stratified cluster sampling. The instruments used were the Strengths and Difficulties Questionnaire (SDQ), the Positive and Negative Affect Schedule for Children (PANAS-C), the Personal Wellbeing Index-School Children (PWI-SC), the ad hoc academic performance questionnaire, and the Oviedo Scale of Response Infre…

Browsing the information highway while driving: three in-vehicle touch screen scrolling methods and driver distraction

2012

Distraction effects of three alternative touch screen scrolling methods for searching music tracks on a mobile device were studied in a driving simulation experiment with 24 participants. Page-bypage scrolling methods with Buttons or Swipe that better facilitate resumption of visual search following interruptions were expected to lead to more consistent in-vehicle glance durations and thus, on less severe distraction effects than Kinetic scrolling. As predicted, Kinetic scrolling induced decreased visual sampling efficiency and increased visual load compared to Swipe, increased experienced workload compared to both Buttons and Swipe, as well as decreased lane keeping accuracy compared to ba…

Measuring Distraction at the Levels of Tactical and Strategic Control: The Limits of Capacity-Based Measures for Revealing Unsafe Visual Sampling Mod…

2011

The control theory of driving suggests that driver distraction can be analyzed as a breakdown of control at three levels. Common approach for analyzing distraction experimentally is to utilize capacity-based measures to assess distraction at the level of operational control. Three driving simulation experiments with 61 participants were organized to evaluate which kind of measures could be used to analyze drivers' tactical visual sampling models and the related effects of distraction while searching textual information on in-car display. The effects of two different text types were evaluated. The utilized capacity-based measures seemed to be insufficient for revealing participants' tactical…

Darba samaksa un ar to saistīto nodokļu analīze

2018

Ik gadu LR normatīvajos aktos veic izmaiņas. 2018. gadā paredzētas izmaiņas darba samaksas aprēķinos. Darba mērķis ir, pamatojoties uz normatīvo aktu un speciālās literatūras izpēti, noskaidrot, kuram šīs normatīvo aktu izmaiņas ir izdevīgas. Mērķa sasniegšanai noteikti uzdevumi: •Noskaidrot, kas ir darba samaksa un kādi nodokļi ar to saistīti; •Izpētīt 2017.gada normatīvos aktus un izanalizēt, kādas izmaiņas gaidāmas 2018. gadā saistībā ar darba samaksas aprēķināšanu; •Noskaidrot, ar kādām izmaiņām jārēķinās katrai iesaistītajai pusei 2018. gadā; •Izdarīt secinājumus par veiktajiem pētījumiem. Pētījuma veikšanā izmantoti LR normatīvie akti un uzņēmuma dokumenti. Pētījumā tiek izmantotas ma…

Passive sampling in monitoring of nonylphenol ethoxylates and nonylphenol in aquatic environments

2012

The present practices for determining the concentration levels of various pollutants are in many respects insufficient and for this reason, there is an urgent need especially to develop more cost-effective sampling methods. In this study, a novel passive sampling tool (the Chemcatcher®) for monitoring nonylphenol ethoxylates (NPEOs) and nonylphenol (NP) in aqueous media was tested. These environmentally harmful substances have been widely used in different household and industrial applications and they affect aquatic ecosystems, for example, by acting as endocrine disrupting compounds. The highest accumulation of NPEOs and NP in laboratory-scale tests was obtained when using an SDB-XC (stan…

Apcietinājuma termiņi kriminālprocesā

2016

Bakalaura darbā "Apcietinājuma termiņi kriminālprocesā" uzmanība vērsta uz apcietinājuma un apcietinājuma termiņu regulējumu Latvijas Republikas Kriminālprocesa likumā un ar to saistīto problemātiku praksē, kā arī meklēta atbilde uz pētījuma jautājumu, vai ir pieļaujami secināt, ka apcietinājuma termiņi ir nepamatoti gari vai nesamērīgi, vērtējot tos abstrakti (pat subjektīvi), neņemot vērā lietas sevišķos apstākļus. Bakalaura darba mērķis ir (a) izvērtēt tiesisko regulējumu, kas nosaka apcietinājuma pamatu un (b) apcietinājuma termiņus, (c) izvērtēt apcietinājuma termiņu teorētiskos un praktiskos aspektus un ar tiem saistīto problemātiku, kā arī (d) noskaidrot, kādi objektīvi kritēriji att…
