Barriers to Freedom of Contract in the Public Sector
Currently twenty-four states have "right-to-work" laws, which primarily restrict the rights of workers and employers in the private sector from entering into certain kinds of labor contracts. Federal labor law mandates that unions represent all workers at a workplace, whether they are dues-paying members of the union or not. Meanwhile, state "right-to-work" laws prohibit workers and employers from signing contracts that require all covered workers to contribute to the costs of representation regardless of whether or not the workers choose to join the union
Regulation of Public Sector Collective Bargaining in the States
While the unionization of most private-sector workers is governed by the National Labor Relations Act (NLRA), the legal scope of collective bargaining for state and local public-sector workers is the domain of states and, where states allow it, local authorities. This hodge-podge of state-and-local legal frameworks is complicated enough, but recent efforts in Wisconsin, Michigan, Ohio, and other states have left the legal rights of public-sector workers even less transparent.In this report, we review the legal rights and limitations on public-sector bargaining in the 50 states and the District of Columbia, as of January 2014. Given the legal complexities, we focus on three sets of workers who make up almost half of all unionized public-sector workers: teachers, police, and firefighters, with some observations, where possible, on other state-and-local workers. For each group of workers, we examine whether public-sector workers have the right to bargain collectively; whether that right includes the ability to bargain over wages; and whether public-sector workers have the right to strike
Synaptic Inhibition Influences the Temporal Coding Properties of Medial Superior Olivary Neurons. An in vitro Study
The medial superior olive (MSO) functions as a coincidence detector for interaural time and phase differences by integrating excitatory synaptic inputs. Recent studies demonstrating glycinergic projections to MSO neurons suggest that coincidence detection results from the temporal integration of both EPSPs and IPSPs. We examined the impact of synaptic inhibition on the temporal coding properties of gerbil MSO neurons in vitro with intracellular recordings and electrical stimulation. For low-level bilateral electric stimulation, the EPSPs summated to produce an action potential in 73% of MSO neurons if they occurred within 50–500 microseconds of one another. Synaptic inhibition became more prominent at higher stimulus amplitudes in 73% of MSO neurons, and could block an evoked action potential if the stimuli to each pathway were delivered within 250 microseconds of one another. The glycine receptor antagonist strychnine influenced the response to simulated interaural time differences. In the presence of strychnine, interstimulus delays that originally resulted in full action potential suppression were sufficient to evoke an action potential. For trains of stimuli, as stimulus intensity increased (spatial summation), or as stimulus repetition rate increased to 100–500 Hz (temporal summation), there was a decrease in the number of stimulus pulses that evoked an action potential. In the presence of strychnine, MSO neurons generated a greater percentage of action potentials to the stimulus trains. When stimulus trains were delivered bilaterally, MSO neurons fired a greater number of action potentials at specific interstimulus time differences, and were selectively inhibited at other time differences.(ABSTRACT TRUNCATED AT 250 WORDS)</jats:p
State Union Membership, 2012
On January 23, the Bureau of Labor Statistics (BLS) released its estimates for union membership in the United States in 2012. This issue brief focuses on the union membership numbers by state. In addition to presenting the BLS estimates for overall union membership in each state, we also provide our own breakdown of state union membership in the private and public sector
No-Vacation Nation Revisited
This report reviews the most recently available data from a range of national and international sources on statutory requirements for paid vacations and paid holidays in 21 rich countries (16 European countries, Australia, Canada, Japan, New Zealand, and the United States). In addition to our finding that the United States is the only country in the group that does not require employers to provide paid vacation time, we also note that several foreign countries offer additional time off for younger and older workers, shift workers, and those engaged in community service including jury duty. Five countries even mandate that employers pay vacationing workers a small premium above their standard pay in order to help with vacation-related expenses. Most other rich countries have also established legal rights to paid holidays over and above paid vacation days. We distinguish throughout the report between paid vacation -- or paid annual leave, terms we use interchangeably -- and paid holidays, which are organized around particular fixed dates in the calendar. Our analysis does not cover paid leave for other reasons such as sick leave, parental leave, or leave to care for sick relatives
A synaptic nidogen: developmental regulation and role of nidogen-2 at the neuromuscular junction
Background: The skeletal neuromuscular junction is a useful model for elucidating mechanisms that regulate synaptogenesis. Developmentally important intercellular interactions at the neuromuscular junction are mediated by the synaptic portion of a basal lamina that completely ensheaths each muscle fiber. Basal laminas in general are composed of four main types of glycosylated proteins: laminins, collagens IV, heparan sulfate proteoglycans and nidogens (entactins). The portion of the muscle fiber basal lamina that passes between the motor nerve terminal and postsynaptic membrane has been shown to bear distinct isoforms of the first three of these. For laminins and collagens IV, the proteins are deposited by the muscle; a synaptic proteoglycan, z-agrin, is deposited by the nerve. In each case, the synaptic isoform plays key roles in organizing the neuromuscular junction. Here, we analyze the fourth family, composed of nidogen-1 and -2.Results: In adult muscle, nidogen-1 is present throughout muscle fiber basal lamina, while nidogen- 2 is concentrated at synapses. Nidogen-2 is initially present throughout muscle basal lamina, but is lost from extrasynaptic regions during the first three postnatal weeks. Neuromuscular junctions in mutant mice lacking nidogen-2 appear normal at birth, but become topologically abnormal as they mature. Synaptic laminins, collagens IV and heparan sulfate proteoglycans persist in the absence of nidogen-2, suggesting the phenotype is not secondary to a general defect in the integrity of synaptic basal lamina. Further genetic studies suggest that synaptic localization of each of the four families of synaptic basal lamina components is independent of the other three.Conclusion: All four core components of the basal lamina have synaptically enriched isoforms. Together, they form a highly specialized synaptic cleft material. Individually, they play distinct roles in the formation, maturation and maintenance of the neuromuscular junction
North versus South : Perception of New Jersey Dialects
Previous studies have found marked differences among regional dialects amidst both large and small geographic locations. This study expands upon previous work on the perception of dialectical differences between Northern and Southern New Jersey. According to previous research, a major dialect boundary splits New Jersey into the two regions of Northern and Southern New Jersey. These two dialects have been found to be influenced by the New York City and Philadelphia dialects, respectively. In this study, a set of 28 talkers (14 male, 14 female) with an even amount from Northern and Southern New Jersey provided sentence-length speech samples which permitted comparisons of various dialect markers. Listeners were given a task where they were asked to identify if a talker was from Northern or Southern New Jersey based on the listener’s perception of the talker’s dialect. The task included two conditions (4 talkers vs. 12 talkers) and included Recognition, Test, and Generalization phases. Overall, listeners were able to identify dialect region for speech samples when provided with previous exposure to the dialect. Listeners made significantly more correct answers in the 4 talker condition than the 12 talker condition. It was also found that listeners’ scores improved as they progress through the first Recognition and Test phases of the identification task but decreased when performing the Generalization phase. These findings indicate that the subtle and variable differences in the dialect markers for Northern and Southern New Jersey are apprehended by listeners and can affect a listener’s judgment of a talker
Motor “Binding:” Do Functional Assemblies in Primary Motor Cortex Have a Role?
AbstractIn this issue of Neuron, Jackson and colleagues describe a functional correlate of neural synchrony related to movement control. Synchrony strength in cortico-motoneuronal output neurons in primary motor cortex depended upon similarity of these neurons' connectivity pattern with the spinal cord. These results could form the foundation for subsequent investigations of motor binding
