<p>In many earlier investigations a recall advantage of auditory lists spoken in a single voice has been found over recall of lists spoken in two alternating voices. One explanation proposed is an organization strategy which makes recall of alternating-voice lists so difficult. The strategy implies sorting same-voice words into same-voice groups at encoding. Based on this proposition, it was assumed that voice-by-voice recall would be better than recall in order of presentation, as then the recall instruction and the organization of items in memory would be in concordance. The present experiment tested and was unable to support this hypothesis. However, an intriguing interaction between recall instruction and the sex of the participants was found, indicating that males perform worse in the voice-by-voice recall instruction than in serial recall while females’ performance did not differ between the two recall instructions. Implications of these results are discussed.</p>

Den digitala utvecklingen får konsekvenser för arbetslivet och dess organisering. I studien undersöks genom fem semistrukturerade intervjuer hur fackligt aktiva orderplockare resonerar kring plocksystemet genom vilket de utför sitt jobb och hur de digitala systemen påverkar maktförhållanden på arbetsplatsen.   Respondenterna arbetar alla inom livsmedelsdistribution på arbetsplatser som arbetar med det digitala plocksystemet pick-by-voice (PbV). Med utgångspunkt i Edwards (1979) tre övergripande kontrollmekanismer styrning, utvärdering och disciplinering samt Kelloggs (2020) sex mekanismer genom vilka algoritmisk kontroll utövas, de så kallade 6R:en, undersöks hur den digitala utvecklingen påverkar möjligheten för arbetsmarknadens parter att utöva kontroll och göra motstånd i arbetsprocessen. Studien finner att PbV innebär att flera arbetsledande funktioner flyttas till det tekniska systemet. Detta innebär en starkare styrning av arbetet genom att systemet begränsar de anställdas handlingsutrymme och en mer omfattande utvärdering och disciplinering genom att varje arbetsmoment loggas på individnivå. Genom realtidsutvärdering sker disciplineringen dels genom självdisciplinering, dels genom belöning för de som rankas högt enligt måltalen och bestraffning för de som inte lever upp till förväntningarna. Här fungerar tillgång till helgarbete, fasta anställningar och rotation som motiverande instrument. Studien finner också att de bemanningsanställda disciplineras hårdare då de pressas genom otryggheten i anställningen. Genom det digitala systemet blir kontrollen främst algoritmisk. Samtidigt förefaller den direkta kontrollen samverka med den algoritmiska kontrollen i utdelandet av både belöningar och bestraffningar utifrån den digitala utvärderingen. Detta motverkar institutionaliserandet av makt i det tekniska systemet och skapar konfliktytor kring det digitala systemet.

Previous research has shown that the reactive paradigm is suitable for programming by voice, due to its frequent use of expressions used in common English. However, the software used in the previous research (Talon) does not support reactive programming. To our knowledge, no other programming-by-voice software has built-in support for RxJava. The main focus of this study is the development and testing of a vocal programming environment that recognizes RxJava operators and commands. This is done by writing custom scripts that form a RxJava-adapter for a software called Serenade. The purpose of the adapter is to determine to what degree customization can improve the programming-by-voice experience, in terms of reduced cognitive and vocal load. The testing process also reveals challenges related to programming-by-voice in reactive Java, as well as challenges related to creating custom voice commands for Serenade. The results indicate that Serenade is superior to Talon, requiring on average 45\% fewer words to produce the same code. When the default version of Serenade is compared to the custom version with custom voice commands, the improvement is 19\%. The study also concludes that there are many challenges facing speech recognition when used in a programming environment. The custom script feature in Serenade, while still having some limitations, is advanced and allows the user to create complex custom voice commands.

I industriföretag används managementverktyg för att utveckla och effektivisera verksamheten så att ledtider och slöseri reduceras i samtliga processer. Parker PMDE Trollhättan tillverkar hydraulikmaskiner. Sedan 90-talet har Parker bedrivit verksamhetsutveckling enligt management principer i Lean Production. Ett nästa steg i Parkers ständiga förbättringsarbete var att undersöka möjligheter att utveckla en materialsatsningsavdelning så att en person kan förse monteringen med material tillräckligt snabbt utan att extra resurser behöver tillsättas. I dagsläget råder det obalans gentemot takttider i monteringen och det tar längre tid för satsningen att plocka ihop fyra satser än vad det tar för monteringen att förbruka dessa satser.Målet med examensarbetet var att ta fram förbättringsförslag där en person får förutsättningar att plocka ihop material till montering av fyra hydraulikmaskiner på mindre än 16 minuter. Delmålen var att göra en kartläggning av tider och arbetsmoment vid satsningen. Avgränsningarna i projektet var att inte undersöka processer utanför satsningen. Examensarbetet utformades efter DMAIC-metodiken, som är en projektmodell för faktabaserad problemlösning och tydlig struktur. Metoderna som användes vid insamling av data var observationer och analys av videoinspelat material som utfördes i programvaran AviX Method. Videoinspelningarna kategoriserades som olika aktiviteter i satsningsprocessen där gång, plock, scannertid, förmontering och övrig tid var de största kategorierna. Arbetsmoment identifierades som var tidskrävande och ej tillförde värde i processen. Mätningarna låg till grund för generering av lösningsförslagen.Baserat på ovanstående resultat och med hjälp av brainstorming genererades lösningsförslag tillsammans med produktionstekniker och materialhanterare. De lösningsförslag som uppfyllde målet med projektet att plocka en 4-sats under 16 minuter var pick by voice, pick by light, ringscanner och flytt av kilpress. Pick by voice anses vara lösningen som företaget bör införa eftersom den reducerar plocktid, scannertid och är ett flexibelt system. Ytterligare två lösningsförslag togs fram som inte uppfyllde målet men uppfattas som värda för företaget att utreda vidare utifrån Lean Production och ergonomiska skäl. De lösningsförslagen som inte uppfyllde målen bestod av en förändring av plockrundan och införande av en magnetlyft. / In industries, the management tools of Lean Production are used to develop and streamline operations in a way to reduce waste and lead times in all processes. Parker PMDE in Trollhättan manufactures hydraulic machines. Since the 90´s, Parker has pursued business development under the management principles of Lean Production. One of the next steps in Parkers continuous improvement was to explore opportunities to develop a kitting department so that a worker could provide the assembly with the material quickly without surplus resources. In the current situation, there is an imbalance from the kitting station towards the tact times in the assembly station because it takes longer at the kitting station to pick materials for four hydraulic machines, than it takes for the assembly station to consume these kits of materials.The aim of the thesis was to develop suggestions for improvement where a worker could perform the kitting process in less than 16 minutes. The interim objectives were to do a survey of the times and activities within the kitting process. The boundaries of the project was not to examine processes outside the kitting station. The project was designed according to DMAIC methodology, which is a project model for fact-based problem solving and clear structure. The methods used in the data collection were observation and analysis of video footage applying the software called AviX Method. Video recordings were categorized as different activities in the kitting process such as transport, picking, scanner time, pre-assembly and uncategorized time. Activities that were time consuming and did not add value to the process were identified. These data measures were the basis for the solution proposals.Based on these results and using brainstorming, solution proposals were generated together with the engineers and material handlers. The solution proposals that met the objective of the project of picking a 4-set of materials in 16 minutes were: Pick by voice, Pick-by-light, Ring Scanner and Relocation of one pre-assembly operation. Pick by voice is considered to be the most appropriate solution for the company since it reduces picking times, scanning times and is a flexible system. Two more proposed solutions were developed that did not meet the objective of the project, but are considered worth investigating further based on Lean Production and ergonomic reasons. These proposed solutions consisted of changing the picking route and the installation of a magnetic lift.

Titel: Från periodisk inventering utan Pick By Voice till rullande inventering med Pick By Voice - En fallstudie på Företag X Bakgrund och problem: Företag X har valt att implementera plocktekniken Pick By Voice, samtidigt som företaget ser över möjligheten att implementera en rullande inventering i samband med detta. Frågor som uppstår är vad lagar och praxis säger för området samt hur en möjlig implementering av rullande inventering bör se ut. Syfte: Syftet med uppsatsen är att genom en kvalitativ studie undersöka behovet av en ny inventeringsmetod genom en förstudie och därefter utveckla en inventeringsprocess passande efter Företag X förutsättningar. Denna inventeringsprocess ska kunna användas i samspel med Pick By Voice. Vidare är också att uppmuntra andra företag inom likartad bransch att se över sin nuvarande inventeringsmetod och om de kan implementera en liknande förändring av rullande inventering med Pick By Voice. Metod: Denna studie är en kvalitativ fallstudie. Insamlingen av empiri har skett genom utförandet av semistrukturerade och ostrukturerade intervjuer med företag och revisionsbyråer. Slutsats: En nu 65 år gammal skattelag säger att företag måste inventera sina lager minst en gång om året. Som en otillräcklig beskrivning av hur detta ska göras, samtidigt som lagerhanteringssystemet får ny utveckling, har detta lagt större vikt vid nuvarande praxis. Detta är särskilt så när ett företag implementerar en rullande inventeringsmetod. Viktiga steg i implementeringsprocessen bekräftas vara avgörande för företag att uppfylla. Dels för att lyckas med implementeringen, men också för att säkerställa en tillfredsställande inventeringsprocess och undvika att både misstag i implementerings- och inventeringssprocessen uppstår. Att kombinera den rullande inventeringen med röstplocktekniken Pick By Voice anses även det vara betydande för att reducera ytterligare misstag som förekommer eller kan förekomma i inventeringsprocessen. Hur frekvent företag bör inventera grundar sig i; vilken typ av marknad företaget är verksamt på, andelen misstag som uppstår i inventeringsprocessen och om fler antal inventeringar kan bidra till fler besparingar för företaget. / Title: From periodic inventory without Pick By Voice to continuous inventory with Pick By Voice - A case study at Company X Background and problem: Company X has chosen to implement the Pick By Voice picking technology, while at the same time considering the possibility of implementing a continuous inventory in connection with this. Questions that arise are what the laws and practices say for this area and what a possible implementation of continuous inventory should look like. Purpose: The purpose of this thesis is to investigate the need for a new inventory method through a pilot study and then develop an inventory process suitable for Company X conditions. This inventory process should be used in interaction with Pick By Voice. Furthermore, other companies in similar industries are also encouraged to review their current inventory method and whether they can implement a similar change of continuous inventory with Pick By Voice. Method: This study is a qualitative case study. The collection of empirical data has been carried out through the conduct of semi structured and unstructured interviews with companies and accounting firms. Conclusion: A now 65 years old tax law says that companies need to count their inventory at least once a year. As there is an insufficient description of how this should be done, while also warehouse management system get new development, this has placed greater emphasis on current practice. This so, especially when a company is implementing a continuous inventory method with Pick By Voice. Important steps in the implementation process have been confirmed to be crucial to fulfil by the company. Especially in order to achieve a successful implementation of the process, ensure that the process fulfil its required satisfaction level and to avoid occurrence of mistakes in the implementation process as well as in the inventory process. The combination of continuous inventory and Pick By Voice is considered to be significant in the reduction of further mistakes that occur or can occur in the inventory process. The determination of the inventory frequency is dependent on; type of market that the company operates in, number of occurring mistakes in the inventory process and if an increase in number of inventory occasions can contribute to an increase in the savings.

Elections are one of the most fundamental activities of a democratic society. As is the case in any other aspect of life, developments in technology have resulted changes in the voting procedure from using the traditional paper-based voting to voting by use of electronic means, or e-voting. E-voting involves using different forms of electronic means like / voting machines, voting via the Internet, telephone, SMS and digital interactive television. This thesis concerns voting by telephone, or televoting, it starts by giving a brief overview and evaluation of various models and technologies that are implemented within such systems. The aspects of televoting that have been investigated are technologies that provide a voice interface to the voter and conduct the voting process, namely the Election Markup Language (EML), Automated Speech Recognition (ASR) and Text-to-Speech (TTS).
