SummarySince Germany’s social assistance reform (“Hartz-IV-Reform”) in 2005 there has been a strong increase in the number of working poor and long-term unemployed. This development is often attributed to the remaining disincentives of the reformed social assistance to take up a low-paid full time job. Therefore, several proposals have been worked out to reduce these disincentives. In this paper we analyse an in-work benefit programme considered by the German government, which follows the proposal of Bofinger et al. (2006). We employ a microsimulation model for estimating labour supply as well as distributional and fiscal effects of this reform proposal.We provide “morning after effects”, i.e. fiscal effects without considering behavioural adjustments, and long run effects, which take into account the labour supply response following the introduction of the reform.We predict the labour supply responses by estimating a discrete choice model for different household types and find a moderate increase in labour supply (103,000 full-time equivalents) as well as overall low negative participation effects. The distributional analysis reveals an overall increase in poverty rates caused by lower earnings disregards as well as substantial deadweight losses, since a large part of the in-work benefit accrues to households who do not belong to the working poor in the status quo.

In the late sixties, women in the United States became sensitized to their second-class status and organized to raise their consciousness and change their conditions. At the same time women in academia began to organize within their disciplines to address the problems they faced there. Political science was no exception; in 1969, when women constituted 5 percent of the membership of the APSA and 8 percent of all political science faculty teaching in colleges and universities, the APSA Committee on the Status of Women in the Profession and the Women's Caucus for Political Science formed. Numerous reports have revealed a moderate increase in the presence of women in the profession in recent years. As Table 1 shows, the percentage of degrees in political science awarded to women has increased since 1970. By the academic year 1976–77 women constituted 11 percent of full-time faculty and 18 percent of part-time faculty. Twenty-three percent of the students entering Ph.D. programs in 1977 were women, a downturn of 3 percent from the previous year, although an overall rise from the previous decade.

The Cost

Abstract Income support for working low-income families (the ‘working poor’) is on top of the political agenda in Switzerland. The current social assistance system is considered inadequate to support working poor households. Several European countries have introduced in-work benefits in order to make work pay. Based on a structural labour supply model, this paper provides microsimulation results of the effects of introducing different schemes of in-work benefits. It turns out that adding a minimum hours requirement to the current social assistance system is the most cost-effective reform. Onethird of expected costs can be attributed to behavioural changes in labour supply.

This paper discusses the status and implications of the employment relations and working conditions experienced by digital platform workers; the analysis is based on a survey conducted in 2017 on 1 338 workers engaged in work-on-demand via apps (WODVA) from 25 platforms in Beijing, of whom 48.8 % are full-time WODVA workers or take WODVA as their primary job. The survey finds that nearly a half of the respondents engage in platform work due to a lack of employment opportunities in formal labor markets or their permanent jobs providing insufficient income. The respondents reveal substantial decent work deficits in representation, compensation, job stability, social protection, working time, and health and safety: 1) WODVA workers seldom have any voice in labor dispute settlements and have a very low rate of unionization; 2) about one third of the full-time WODVA workers cannot earn a living wage and 7.6 % of them earn less than the minimum wage level; 3) three quarters of the full-time WODVA workers have no labor contract with the platforms or other employers, nor access to employer-contributed social insurances; 4) overtime work and underemployment coexist among full-time respondents, with nearly 10 % working for fewer than 4 hours per day while nearly 10 % work for more than 11 hours per day; 5) a majority of respondents run a higher risk of occupational health or physical risks, without any protection provided by the platforms or employers. To promote decent work by digital platform workers, the State needs to establish a portable social security system extending to all workers, to facilitate association and collective actions of platform workers either by extending the outreach of traditional unions or fostering new forms of organizations, to leverage digital technology to facilitate platform workers’ organization and information sharing, and even to promote universal basic income and a workers’ cooperative of platforms in the long run.

In this article, the effect on the vibrational and thermal properties of gradually interconnected nanoinclusions embedded in an amorphous silicon matrix is studied using molecular dynamics simulations. The nanoinclusion arrangement ranges from an aligned sphere array to an interconnected mesh of nanowires. Wave-packet simulations scanning different polarizations and frequencies reveal that the interconnection of the nanoinclusions at constant volume fraction induces a strong increase of the mean free path of high frequency phonons, but does not affect the energy diffusivity. The mean free path and energy diffusivity are then used to estimate the thermal conductivity, showing an enhancement of the effective thermal conductivity due to the existence of crystalline structural interconnections. This enhancement is dominated by the ballistic transport of phonons. Equilibrium molecular dynamics simulations confirm the tendency, although less markedly. This leads to the observation that coherent energy propagation with a moderate increase of the thermal conductivity is possible. These findings could be useful for energy harvesting applications, thermal management or for mechanical information processing.

Abstract The working poor are not a clearly defined group. There are still people who work full-time, but have incomes bordering on poverty level. They tend to remain in work despite their low wages simply to avoid becoming unemployed and risk social exclusion. However, working in low-income jobs for long periods creates stress and gives rise to further problems. Stress affects sleep patterns and leads to problems associated with food intake and nutrition, and thus to disorders of the gastrointestinal system. Cardiovascular and neurological disorders may occur too. A lack of finances, and the stresses stemming from that are statistically significant and a strong predictor of a worse mental state. There is also a higher probability of psychosis occurring. All this affects the entire family, especially children. The inability to invest money and time in their development is another consequence.

In presenting my valedictory to this distinguished Association which has honored me by selecting me as its President, I should like to point out by way of introduction what has happened to this office, and therefore to me, during the past year. I have heard of one of my distinguished predecessors some twenty-five years ago who had little else to do as President of this Association than work all year on his presidential address. This was important work and I have no word of criticism of it. But the Association has changed, and today it leaves to the harried wearer of its presidential toga little time to reflect about the status of political science and his own impact, if any, upon it. An active Association life, now happily centered in our new Washington office, is enough to occupy the full time of your President, and universities as well as this Association might well take note. Therefore, in presenting my own reflections to you this evening in accordance with the custom of our Association, I do so without the benefit of the generous time and scholarly leisure which were the privileges of some of my distinguished predecessors.Nevertheless I do base my presidential address today upon my own active participation in the problems of government, as well as upon my scholarly experience. I have extracted it in part from the dynamics of pulsating political life. It has whatever authority I may possess after having been exposed these twenty-five years to the cross-fire of politics, domestic and foreign, as well as to the benign and corrective influences of eager students and charitable colleagues.

Gamma interferon (IFN-γ) expression plays a crucial role in the control of mammalian hepatitis B virus (HBV) infection. However, the role of duck INF-γ (DuIFN-γ) in the outcome of duck HBV (DHBV) infection, a reference model for hepadnavirus replication studies, has not yet been investigated. This work explored the dynamics of DuIFN-γ expression in liver and peripheral blood mononuclear cells (PBMCs) during resolution of DHBV infection in adolescent ducks in relation to serum and liver markers of virus replication, histological changes and humoral response induction. DHBV infection of 3-week-old ducks resulted in transient expression of intrahepatic preS protein (days 3–14) and mild histological changes. Low-level viraemia was detected only during the first 10 days of infection and was accompanied by early anti-preS antibody response induction. Importantly, a strong increase in intrahepatic DuIFN-γ RNA was detected by real-time RT-PCR at days 6–14, which coincided with a sharp decrease in both viral DNA and preS protein in the liver. Interestingly, liver DuIFN-γ expression remained augmented to the end of the follow-up period (day 66) and correlated with portal lymphocyte infiltration and persistence of trace quantities of intrahepatic DHBV DNA in animals that had apparently completely resolved the infection. Moreover, in infected ducks, a moderate increase was detected in the levels of DuIFN-γ in PBMCs (days 12–14), which coincided with the peak in liver DuIFN-γ RNA levels. These data reveal that increased DuIFN-γ expression in liver and PBMCs is concomitant with viral clearance, characterizing the resolution of infection, and provide new insights into the host–virus interactions that control DHBV infection.

Despite the positive developments in the sphere of ensuring the special needs of disabled children, a comprehensive socio-hygienic assessment of the conditions and lifestyles, as well as of their families, has not been carried out in the recent years. The purpose of the study is to identify, through a sociological survey, the problems that a disabled child encounters in his life, in order to further improve the provision of medical and social assistance to him. Materials and methods of research: 506 legal representatives of minors (aged 0–17 years) with the status of a disabled child were interviewed. Study design: single-center, non-randomized, uncontrolled. Results: the study of the living conditions of a disabled child in the family, the assessment by the parents of the state of his health, the problems arising during the registration of disability, in the provision of medical and rehabilitation assistance, and issues of medical and social support, made it possible to determine the position of this part of the child population in modern legal and medical and social conditions. The main problems were the large number of documents required for the registration of a disability, the long wait for the day of the examination, the remoteness of the location of the medical and social examination bureau, the shortage of specialist doctors, the problem with subsidized drugs, the lack of taking into account the individual needs of the child when carrying out rehabilitation programs, the need to contact different organizations and departments, lack of medical and social assistance, violation of rights in the provision of medical services to a disabled child. Conclusion: The acquired information is important for the further improvement of the provision of medical and social assistance to handicapped children and children with disabilities. The main task today is to develop mechanisms for fulfilling the declared rights and freedoms of persons with disabilities and the obligations undertaken by the state in relation to them. The principle of individualization of the provision of various benefits, depending on the condition of a disabled child, his needs, material security, remains relevant.

Protocol Architecture

LoRa Wide Area Networks (LoRaWAN) can provide a connectivity service to Internet of Things (IoT) for an extremely long run-time and with low power consumption. As the LoRaWAN is extensively applied to various IoT scenarios, LoRaWAN solutions face a flexibility issue in terms of inter-operating with various kinds of LoRa modem hardware and protocol scenarios. In this regard, we design a unified protocol architecture for LoRaWAN physical layer, which can flexibly correspond to various deployment and operational cases. The new protocol architecture includes a hardware abstraction sub-layer, which contains generalized handlers for configuring various kinds of the LoRa modem, and a physical procedure sub-layer that structurally models the physical layer procedures of the LoRaWAN based on Finite State Machine(FSM). We illustrate the flexibility of the new protocol architecture by implementing an extensive feature that enhances the packet reception ratio based on the status of preamble detection. For evaluating the new protocol architecture, we implement the LoRaWAN physical layer protocol on real-time embedded systems and conduct experiments. The experimental results show that the proposed protocol robustly transmits and receives packets and generates little amount of additional burden compared with the conventional open source protocol provided by SemTech.
