Continuously measured 222Rn activity concentrations (daily means) in near surface air at Neumayer Station in the period 1995 through 2011

We report on continuously measured 222Rn activity concentrations in near-surface air at Neumayer Station in the period 1995-2011. This 17-year record showed no long-term trend and has overall mean ± standard deviation of (0.019 ± 0.012) Bq/m**3. A distinct and persistent seasonality could be distinguished with maximum values of (0.028 ± 0.013) Bq/m**3 from January to March and minimum values of (0.015 ± 0.009) Bq/m**3 from May to October. Elevated 222Rn activity concentrations were typically associated with air mass transport from the Antarctic Plateau. Our results do not support a relation between enhanced 222Rn activity concentrations at Neumayer and cyclonic activity or long-range transport from South America. The impact of oceanic 222Rn emissions could not be properly assessed but we tentatively identified regional sea ice extent (SIE) variability as a significant driver of the annual 222Rn cycle.

Utilizing ICT to prevent loneliness and social isolation of the elderly. A literature review

Ageing of the population is a worldwide phenomenon. Numerous ICT-based solutions have been developed for elderly care but mainly connected to the physiological and nursing aspects in services for the elderly. Social work is a profession that should pay attention to the comprehensive wellbeing and social needs of the elderly. Many people experience loneliness and depression in their old age, either as a result of living alone or due to a lack of close family ties and reduced connections with their culture of origin, which results in an inability to participate actively in community activities (Singh & Misra, 2009). Participation in society would enhance the quality of life. With the development of information technology, the use of technology in social work practice has risen dramatically. The aim of this literature review is to map out the state of the art of knowledge about the usage of ICT in elderly care and to figure out research-based knowledge about the usability of ICT for the prevention of loneliness and social isolation of elderly people. The data for the current research comes from the core collection of the Web of Science and the data searching was performed using Boolean? The searching resulted in 216 published English articles. After going through the topics and abstracts, 34 articles were selected for the data analysis that is based on a multi approach framework. The analysis of the research approach is categorized according to some aspects of using ICT by older adults from the adoption of ICT to the impact of usage, and the social services for them. This literature review focused on the function of communication by excluding the applications that mainly relate to physical nursing. The results show that the so-called ‘digital divide’ still exists, but the older adults have the willingness to learn and utilise ICT in daily life, especially for communication. The data shows that the usage of ICT can prevent the loneliness and social isolation of older adults, and they are eager for technical support in using ICT. The results of data analysis on theoretical frames and concepts show that this research field applies different theoretical frames from various scientific fields, while a social work approach is lacking. However, a synergic frame of applied theories will be suggested from the perspective of social work.

Migrant domestic workers, vulnerability and the law: immigration and employment laws in Cyprus and Spain

The intersection of gender, welfare and immigration regimes has been one of the main focus of a rich scholarship on paid domestic work in Europe. This article brings into the discussion the nexus of employment and immigration law regimes to reflect on the role of legal regulation in structuring and reducing the vulnerability of domestic workers. I analyse this nexus by looking at the cases of Cyprus and Spain, two states falling under the cluster of Southern Mediterranean welfare regimes, that share certain characteristics in terms of immigration regimes, but have substantially different employment law regulation models. The first part sketches the debate on the employment law regulation of domestic work. The second part starts by giving an overview of the immigration regimes of Cyprus and Spain in relation to migrant domestic workers and then proceeds to analyse the two countries’ models and substance of employment law regulation in domestic work. The comparison of these two divergent approaches informs the debate on how the legal regulation of domestic work should be best structured. In Spain there have been recent dynamic legislative changes in the employment law regulation of domestic work. The final part of the article traces these changes and reflects on why such processes have not taken place in Cyprus.

Risk Consumption: Children and Online Gaming. The Problem of “Responsible Gambling”

Online gambling is a popular activity among adolescents. However, there has been a notable increase in the number of young people who suffer or are on the verge of pathological gambling. We review the impact of online gambling on young people and discuss the desiderability of the concept of “gambling responsibly” in order to alert of their risks and effectively prevent access to minors. The main factors associated with pathological gambling are the age of start, the family environment, the infl uence of advertising, the consumption of stimulants, and the attitudes of the peer group. Both the government and the gaming industry itself should consider these factors and develop comprehensive plans that ensure a safe and controlled model game. In this context, advertising must take into account criteria of consumer protection knowing that even if they are not allowed, children can easily have access to online gambling. All agents involved, including public and social agents, must provide mechanisms for prevention and awareness of a problem that arouses little social consciousness and excessive carelessness.

I/Q imbalance in two-way AF relaying: Performance analysis and detection mode switch

This paper studies the impact of in-phase and quadrature-phase imbalance (IQI) in two-way amplify-and-forward (AF) relaying systems. In particular, the effective signal-to-interference-plus-noise ratio (SINR) is derived for each source node, considering four different linear detection schemes, namely, uncompensated (Uncomp) scheme, maximal-ratio-combining (MRC), zero-forcing (ZF) and minimum mean-square error (MMSE) based schemes. For each proposed scheme, the outage probability (OP) is investigated over independent, non-identically distributed Nakagami-m fading channels, and exact closed-form expressions are derived for the first three schemes. Based on the closed-form OP expressions, an adaptive detection mode switching scheme is designed for minimizing the OP of both sources. An important observation is that, regardless of the channel conditions and transmit powers, the ZF-based scheme should always be selected if the target SINR is larger than 3 (4.77dB), while the MRC-based scheme should be avoided if the target SINR is larger than 0.38 (-4.20dB).

Energy efficiency analysis of rank-1 Ricean fading MIMO channels

This paper studies the energy efficiency (EE) of a point-to-point rank-1 Ricean fading multiple-input-multiple-output (MIMO) channel. In particular, a tight lower bound and an asymptotic approximation for the EE of the considered MIMO system are presented, under the assumption that the channel is unknown at the transmitter and perfectly known at the receiver. Moreover, the effects of different system parameters, namely, transmit power, spectral efficiency (SE), and number of transmit and receive antennas, on the EE are analytically investigated. An important observation is that, in the high signal-to-noise ratio regime and with the other system parameters fixed, the optimal transmit power that maximizes the EE increases as the Ricean-K factor increases. On the contrary, the optimal SE and the optimal number of transmit antennas decrease as K increases.

I/Q imbalance in two-way AF relaying: Power allocation and performance analysis

We investigate the performance of dual-hop two-way amplify-and-forward (AF) relaying in the presence of inphase and quadrature-phase imbalance (IQI) at the relay node. In particular, the effective signal-to-interference-plus-noise ratio (SINR) at both sources is derived. These SINRs are used to design an instantaneous power allocation scheme, which maximizes the minimum SINR of the two sources under a total transmit power constraint. The solution to this optimization problem is analytically determined and used to evaluate the outage probability (OP) of the considered two-way AF relaying system. Both analytical and numerical results show that IQI can create fundamental performance limits on two-way relaying, which cannot be avoided by simply improving the channel conditions.

The Democratic Dynamics of Government Consultations. Speaking Freely and Listening Properly

There is a growing use of consultation and e-consultation procedures by governments. This chapter seeks to examine the role of consultation as part of a new technology of government. Consultation on policy development can reinvigorate democratic engage- ment but often it can silence views through a sort of participatory disempowerment; it can loosen the democratic anchorage of the public service within the state. The chapter develops a governmentality perspective interrogating what participation, democratic engagement and free speech mean in this context, and how ideas of publicness are constructed, managed and controlled. The focus is on the nature of consultation, its relationship to ideas of free speech and speaking freely, and its potential to empower subaltern counterpublics which can formulate oppositional interpretations and urge alternative conclusions. The aim is to develop an idea of the democratic adequacy of the consultation process and draw out a sense of how democratic engagement here can be structured – for good or ill.

Språkinlärning i en Ur och Skur praktik : En studie om platsens betydelse för språklärande

Denna uppsats har till syfte att öka kunskap om mellanrummet mellan platsens betydelse och motorikens inverkan på barns språkinlärning i en Ur och Skur verksamhet. Den valda metoden för att försöka få syn på detta mellanrum har varit observationer med fältanteckningar och ljudinspelningar. Sedan har materialet analyserats med hjälp av sociokulturellt perspektiv. Det resultat som framkommit ur mitt empiriska material är att barnens lekar har möjligheten att utvecklas åt många olika håll. Att vara utomhus leder till att de i mindre utsträckning är påverkade av normstyrda artefakter jämfört med en förskola som vistas till större delar inomhus. Dock finns det en social praktik som pedagogerna har skapat som gynnar barns språkinlärning. Strukturen och kulturen av att ställa frågor och ha möjligheten att ge ordentliga svar, i både lek och vardag. Ytterligare ett resultat som framkommit är att både barn och pedagoger är vana vid att använda sin omgivning för att utvidga sitt lärande så att även en skylt i tunnelbanan blev ett medierande redskap för språkinlärning och intresse. Slutsatsen blev att platsen och då främst skogen gav förutsättningarna till rörelse och fantasilek där barnen själva kunde utforska sina intressen. Samtidigt som pedagogerna gav möjligheterna till barnens lekar genom att visa att de tyckte de var viktiga och gav möjligheter för samtal genom bland annat frågelekar.

Large variations in the onset of rippling in concentric nanotubes.

We present a detailed experimental study of the onset of rippling in highly crystalline carbon nanotubes. Modeling has shown that there should be a material constant, called the critical length, describing the dependence of the critical strain on the nanotube outer radius. Surprisingly, we have found very large variations, by a factor of three, in the critical length. We attribute this to a supporting effect from the inner walls in multiwalled concentric nanotubes. We provide an analytical expression for the maximum deflection prior to rippling, which is an important design consideration in nanoelectromechanical systems utilizing nanotubes.

Intellectual Capital Disclosures: The effect of mandatory Integrated Reporting

Purpose – The purpose of this thesis is to investigate how mandatory obligation to follow the International <IR> Framework while producing the corporate reports influence the intellectual capital disclosures in the reports. Research design – The study uses a disclosure scoreboard to score a selected sample of annual reports depending on whether it disclose intellectual capital information or not. The sample consists of companies listed in South Africa were it is mandatory to follow the integrated reporting framework and companies listen in Sweden where it is not mandatory to produce an integrated report. Empirical results and conclusion – The results of this thesis indicates that the mandatory use of the International <IR> Framework have an impact on the amount of intellectual capital disclosures. Further it concludes that higher level of compliance with the framework further increases the intellectual capital disclosure. Contribution – This study has been an early step towards concluding whether the use of integrated reporting has any effect on the amount of intellectual capital information disclosed in companies’ annual report.

Projektmänniskan - Arbetsrehabiliteringens möte med den enskilde

Artikeln handlar om hur välfärdsorganisationer och deras tjänstemän kopplade till aktivitets- och sysselsättningsåtgärder agerar i mötet med den enskilde och vilka berättelser som skapas om individerna. Artikeln diskuterar hur projektdeltagaren omgärdas av en fortgående medikalisering och en social fragmentisering, där projektdeltagarens problematik reduceras och där individens egen röst tycks få ett begränsat utrymme.

Omvårdnadsinterventioners betydelse för strokedrabbade patienters autonomi och delaktighet. : - En litteraturstudie.

Introduktion: Stroke är en sjukdom som kan komma plötsligt och innebära svåra förändringar i det vardagliga livet till följd av funktionsnedsättningar fysiskt, psykiskt och socialt. Inte sällan har det konsekvenser för hur det går att klara av att hantera vardagen och arbetslivet. Genom adekvata omvårdnadsinterventioner kan sjuksköterskan genom sitt kunnande förbättra utfallet för patienter som drabbats av stroke, avseende hälsa och livskvalité. Omvårdnadens primära målsättning är att för den enskilde individen skapa förutsättningar för att denne ska bibehålla autonomi, oberoende och hälsa samt delaktighet. Syfte: Att identifiera omvårdnadsinterventioners betydelse för strokedrabbade patienters autonomi och delaktighet. Metod: Litteraturstudie baserad på Polit och Beck’s (2012) niostegsmodell. Databaser som använts för sökning efter vetenskaplig forskning rörande syftet är CINAHL och PubMed. Antalet artiklar som svarade mot syftet var 14. Resultat: Genom granskning av 14 artiklar skapades två huvudteman Effekter på det dagliga livet och Patientundervisning förstärker egenvårdsförmågan. Båda huvudtemana är av betydelse för strokepatienternas återhämtning fysisk, psykiskt och socialt. Slutsats: Sjuksköterskan har en viktig roll i vården av strokedrabbade patienter, både i den akuta fasen och i eftervården. Oberoende och självkänsla hos strokedrabbade patienter är nedsatt i relation till att de har en försämrad autonomi och möjlighet till delaktighet. Genom olika omvårdnadsinterventioner ökar deras autonomi och möjlighet till delaktighet.
